Definitions

  • the invention relates to an automatic hosiery turning device that can be combined with a linking machine.
  • Such hosiery turning devices are already known, in which a rod or a rail is provided, onto which the tubular knitted fabric of a stocking which has already been closed by sewing at its tip is pulled up and at the same time, starting from the tip, turned with the aid of a pair of counter-rotating parallel rollers which are pressed elastically against the opposite sides of the rod (US-A 4 627 557).
  • an upper pair of rollers for turning is provided, under which a lower pair of rollers for pulling is arranged, the rollers of which are normally spaced apart or "open” so that a stocking can be inserted between them, which is attached to a gripper hangs, which is arranged above the turning rollers.

  • the rod is then moved further down while the take-off rollers "close” and in turn in such a direction that the stocking can be pulled down from the rod.
  • a serious disadvantage of this system is that the zone of contact between the rollers is limited to their generatrix, which lies in a horizontal plane that runs through the roller axes. As a result, the pressure that the rollers exert on the stocking must be relatively high.

Abstract

A working cycle of the stocking turning device begins when a stocking (44), the toe of which has been sewn on a looping machine (41), is taken to its discharge region (40) and is fed there in a centred position into a gripping device (26). Here there is a photocell (43) which delivers a pulse for the start of the cycle once the stocking has reached the exact position. The stocking is thereby taken by the gripping device (26) which is pushed by a carriage (33) travelling on longitudinal guides (34, 35) between two separable belts (7) while the stocking (44) suspended on the gripping device (26) projects between two also separable, endless belts (8) arranged beneath the upper pair of belts (7). The lower end of the stocking hangs beneath the two lower belts (8) in a space between two spread-apart combs (46). When the carriage (33) has reached the end position just described it actuates a magnetic sensor (38) via which the two lower belts (8) and the combs (46) are closed, while the gripping device (26) opens and is taken back via the carriage (33) into its initial position in the discharge region (40) of the looping machine (41). The stocking is held by the closed belts (8). The return of the gripping device (26) actuates another magnetic sensor (39) which causes the upper belts (7) to close and sets both belts (7, 8) rotating in such a direction that their immediately opposite strips go upwards. In addition, a guide rod (3) is abruptly moved downwards and a second photocell (58) fitted between the combs (46) and the lower belts (8) is activated. The guide rod (3) stops shortly above the height at which the second photocell (58) is located. As soon as the free edge of the leg of the turned stocking (44) no longer darkens the photocell (58), the latter spreads the two combs (46) apart and with a slight delay the upper belts (7) are opened, while the guide rod (3) is again retracted upwards and the direction of rotation of the lower belts (8) is reversed. After the turned stocking has been removed from the guide rod (3), the photocell (58) is free once again and causes the lower belts (8) to stop, whereby at the same time the belts of both pairs are opened so that a new turning cycle for the next stocking can begin.

Description

Die Erfindung betrifft ein automatisches Strumpfwendegerät, das mit einer Kettelmaschine kombiniert werden kann.The invention relates to an automatic hosiery turning device that can be combined with a linking machine.

Es sind bereits derartige Strumpfwendegeräte bekannt, bei denen ein Stab oder eine Schiene vorgesehen ist, auf die das schlauchförmige Gewirke eines durch Nähen an seiner Spitze bereits geschlossenen Strumpfes aufgezogen und gleichzeitig, ausgehend von der Spitze, mit Hilfe eines Paares gegenläufig rotierender, paralleler Rollen gewendet wird, die elastisch gegen die gegenüberliegenden Seiten des Stabes gedrückt werden (US-A 4 627 557).Such hosiery turning devices are already known, in which a rod or a rail is provided, onto which the tubular knitted fabric of a stocking which has already been closed by sewing at its tip is pulled up and at the same time, starting from the tip, turned with the aid of a pair of counter-rotating parallel rollers which are pressed elastically against the opposite sides of the rod (US-A 4 627 557).

Bei einer bekannten Bauart dieser Geräte ist ein oberes Rollenpaar zum Wenden vorgesehen, unter welchem ein unteres Rollenpaar zum Abziehen angeordnet ist, dessen Rollen normalerweise einen Abstand zueinander aufweisen oder "geöffnet" sind, damit zwischen diese ein Strumpf eingeführt werden kann, der an einer Greifzange hängt, die oberhalb der Wenderollen angeordnet ist. Auch der Stab befindet sich oberhalb dieser Rollen und bewegt sich abwärts, nachdem die Rollen "geschlossen" und in Drehung versetzt worden sind, so daß der Strumpf auf den Stab bis zu einem ersten Haltepunkt aufgezogen werden kann, welcher zwischen den beiden Rollenpaaren liegt. Danach wird der Stab weiter nach unten bewegt, während die Abzugsrollen "sich schließen" und in einer solchen Richtung drehen, daß der Strumpf nach unten von dem Stab abgezogen werden kann.In a known design of these devices, an upper pair of rollers for turning is provided, under which a lower pair of rollers for pulling is arranged, the rollers of which are normally spaced apart or "open" so that a stocking can be inserted between them, which is attached to a gripper hangs, which is arranged above the turning rollers. The wand is also above these rollers and moves downward after the rollers have been "closed" and rotated so that the stocking can be pulled onto the wand to a first stop which is between the two pairs of rollers. The rod is then moved further down while the take-off rollers "close" and in turn in such a direction that the stocking can be pulled down from the rod.

Ein schwerwiegender Nachteil dieses Systems besteht darin, daß die Berührungszone zwischen den Rollen auf deren Erzeugende begrenzt ist, die in einer horizontalen Ebene liegt, die durch die Rollenachsen verläuft. Das hat zur Folge, daß der Druck, den die Rollen auf den Strumpf ausüben, verhältnismäßig hoch sein muß. Damit ist die Gefahr verbunden, daß das Maschengewebe des Strumpfes beschädigt wird, insbesondere bei Strümpfen aus sehr dünnem Garn, bei bestickten Strümpfen, die links sehr lose Fäden haben, oder bei Frotteestrümpfen für Tennis oder Basket, d.h. aus einem sehr lose gewirkten Gewebe.A serious disadvantage of this system is that the zone of contact between the rollers is limited to their generatrix, which lies in a horizontal plane that runs through the roller axes. As a result, the pressure that the rollers exert on the stocking must be relatively high. This is associated with the risk that the mesh fabric of the stocking will be damaged, in particular with stockings made of very thin yarn, with embroidered stockings that have very loose threads on the left, or with terry stockings for tennis or basket, i.e. from a very loosely knitted fabric.

Ähnliches gilt für die Beschichtung der Rollen, insbesondere der Wenderollen. Die Beschichtungen unterliegen einem erheblichen Verschleiß, der um so rascher eintritt, je empfindlicher das Strumpfgewirke ist, da dieses einen größeren Klemmdruck erfordert.The same applies to the coating of the rollers, in particular the turning rollers. The coatings are subject to considerable wear and tear, the quicker the more sensitive the hosiery is, since this requires a higher clamping pressure.

Ein weiterer Nachteil besteht in der Schwierigkeit, den Stab in den "Sack" einzuführen, der von der Strumpfspitze gebildet wird. Das liegt daran, daß die Spitze leicht gegen eine der beiden Wenderollen abkippt, sobald sie von der Greiferzange freigegeben worden ist.Another disadvantage is the difficulty in inserting the stick into the "sack" formed by the toe of the stocking. This is because the tip tilts easily against one of the two turning rollers as soon as it has been released by the gripper tongs.

Weitere Nachteile sind darin zu sehen, daß aufgrund des Zwischenhaltes des Stabes der Wendezyklus verhältnismäßig lang ist und daß es praktisch unmöglich ist, sehr kurze Strümpfe zu wenden, beispielsweise Kinderstrümpfe mit einer Länge von 12 bis 15 Zentimeter oder weniger.Further disadvantages can be seen in the fact that, due to the intermediate stop of the rod, the turning cycle is relatively long and that it is practically impossible to turn very short stockings, for example children's stockings with a length of 12 to 15 centimeters or less.

Es sind ferner Strumpfwendegeräte bekannt, bei denen zwei vertikal übereinander angeordnete Paare von Bändern den Strumpf wenden, welche elastisch gegen die gegenüberliegenden Seiten eines Stabes wirken, der vertikal nicht beweglich ist. Die beiden unteren Bänder ziehen dabei den Strumpf ab, wozu sie an einer bestimmten Stelle des Zyklus ihre Drehrichtung umkehren und gegen das untere Ende des Stabes drücken (DE-A 34 13 689).Stocking turning devices are also known in which two pairs of bands arranged vertically one above the other turn the stocking and act elastically against the opposite sides of a rod which is not vertically movable. The two lower bands pull off the stocking, for which they reverse their direction of rotation at a certain point in the cycle and press against the lower end of the rod (DE-A 34 13 689).

Bei diesem System wird weder der Strumpf beschädigt noch ist ein rascher Verschleiß der Bänder zu verzeichnen, da die spezifische Anpressung zwischen dem Strumpfgewirke, das gewendet wird, dem Stab und den Bändern verhältnismäßig gering gehalten werden kann. Nachteilig bei diesem bekannten System ist jedoch die Tatsache, daß die Zuführung der Strümpfe zu den Wendeorganen problematisch ist, da diese verhältnismäßig kompliziert ausgebildet sein müssen.With this system, the stocking is not damaged, and there is no rapid wear on the bands, since the specific contact pressure between the knitted hosiery, the bar and the bands can be kept relatively low. A disadvantage of this known system, however, is the fact that the supply of the stockings to the turning organs is problematic since they have to be of a relatively complicated design.

Der Erfindung liegt die Aufgabe zugrunde, ein Strumpfwendegerät zur Verfügung zu stellen, das im Verbund mit einer Kettelmaschine automatisch arbeitet und die erwähnten Nachteile der bekannten Systeme vermeidet, wobei wirksame Maßnahmen vorgesehen sein sollen, um die richtige Lage des Strumpfes während des Wedevorganges auf dem Stab zu kontrollieren.The invention has for its object to provide a hosiery device that works automatically in conjunction with a warping machine and avoids the disadvantages of the known systems, effective measures should be provided to ensure the correct position of the stocking during the wedging process on the rod to control.

Gemäß der Erfindung wird diese Aufgabe durch das Kennzeichen des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing part of patent claim 1.

In vorteilhafter Weiterbildung der Erfindung ist die Bewegungsbahn des Greifers so vorgegeben, daß die Berührungszone zwischen den einander gegenüberliegenden Greifrändern der Backen des Greifers bezüglich der vertikalen Bewegungsebene des Wendestabes seitlich so versetzt ist, daß gegen das untere Ende des Wendestabes der Sack ausgerichtet ist, der auf der Seite der genähten Spitze des Strumpfes ausgebildet ist, welcher vom Greifer erfaßt ist, sobald sich dieser in der inneren Stellung zwischen den beiden oberen Bändern befindet.In an advantageous development of the invention, the movement path of the gripper is predetermined such that the contact zone between the opposing gripping edges of the jaws of the gripper is laterally offset with respect to the vertical plane of movement of the turning bar in such a way that the sack is aligned with the lower end of the turning bar the side of the sewn tip of the stocking is formed, which is gripped by the gripper as soon as it is in the inner position between the two upper bands.

Nach einem weiteren Merkmal der Erfindung ist der Greifer an einem Schlitten gehalten, der an Längsführungselementen verschiebbar gelagert ist, welche von dem Gehäuse in Richtung auf die Abgabezone der mit dem Strumpfwendegerät gekoppelten Kettelmaschine abstehen, wobei die Verschiebung des Schlittens auf den Längsführungselementen von einem Pneumatikzylinder gesteuert wird.According to a further feature of the invention, the gripper is held on a slide which is slidably mounted on longitudinal guide elements which protrude from the housing in the direction of the delivery zone of the linking machine coupled to the stocking turning device, the displacement of the slide on the longitudinal guide elements being controlled by a pneumatic cylinder becomes.

Es ist vorteilhaft, wenn der Greifer eine mit dem Schlitten verbundene, erste Backe sowie eine zweite Backe hat, die über einen Drehzapfen an der ersten Backe angelenkt ist, welcher parallel zu der vertikalen Verschiebeebene des Wendestabes verläuft, wenn sich der Greifer zwischen den beiden oberen Bändern befindet. Auch hier kann zur Bewegung der zweiten Backe relativ zur ersten Backe ein Pneumatikzylinder eingesetzt werden.It is advantageous if the gripper has a first jaw connected to the slide and a second jaw which is articulated on the first jaw via a pivot which runs parallel to the vertical displacement plane of the turning bar when the gripper is between the two upper ones Tapes. Here, too, a pneumatic cylinder can be used to move the second jaw relative to the first jaw.

Wenn das Strumpfwendegerät bei einer Kettelmaschine runder Bauart verwendet wird, ist die erste Backe des Greifers um eine vertikale Drehachse schwenkbar mit dem Schlitten so verbunden, daß sie zwischen einer im wesentlichen tangential zur Umfangslinie des Drehkranzes der Kettelmaschine verlaufenden Stellung und einer parallel zur vertikalen Verschiebeebene des Wendestabes verlaufenden Stellung schwenkbar ist. Die Drehung der ersten Backe relativ zu dem Schlitten wird dabei vorzugsweise von einem Pneumatikzylinder gesteuert.If the hosiery device is used in a round-type warping machine, the first jaw of the gripper is pivotally connected to the slide about a vertical axis of rotation so that it runs between a position which is essentially tangential to the circumferential line of the rotating ring of the warping machine and a position parallel to the vertical displacement plane of the Turning rod extending position is pivotable. The rotation of the first jaw relative to the slide is preferably controlled by a pneumatic cylinder.

Nach einem anderen Merkmal der Erfindung ist vorgesehen, daß die Stabilisierungseinrichtung ein Paar untereinander gleicher, geradlinig verlaufender Kämme hat, welche symmetrisch zu beiden Seiten der vertikalen Verschiebeebene des Wendestabes angeordnet und am oberen Ende von Tragarmen befestigt sind, die ebenfalls untereinander gleich ausgebildet und zu beiden Seiten der vertikalen Verschiebeebene liegen und zu dieser schräg nach unten verlaufen, wobei die unteren Enden an Drehachsen angebracht sind. Um die beiden Kämme relativ zu der vertikalen Arbeitsebene zu bewegen, werden die Tragarme von einem Pneumatikzylinder angetrieben.According to another feature of the invention it is provided that the stabilizing device has a pair of identical, rectilinear ridges which are arranged symmetrically on both sides of the vertical displacement plane of the turning bar and attached to the upper end of support arms which are also identical to one another and to both Sides of the vertical plane of displacement lie and run obliquely downwards to it, the lower ends being attached to axes of rotation. Around the two combs relative to the vertical working plane to move, the support arms are driven by a pneumatic cylinder.

Ein wesentliches Merkmal der Erfindung besteht darin, daß die Tragstrukturen für jedes Band jedes Bandpaares aus plattenoder quaderförmigen Lagerblöcken bestehen, die auf horizontalen Führungen verschiebbar gelagert und paarweise mit einem Pantographen-Hebelsystem verbunden sind, welches über Pneumatikzylinder derart antreibbar ist, daß die Lagerblöcke bei ihrer Verstellbewegung bezüglich der vertikalen Verschiebeebene des Wendestabes immer gleiche Abstände zu dieser Ebene haben. Dabei sind Mittel zum Einstellen des Mindestabstandes zwischen den Lagerblöcken vorgesehen, an denen die jeweiligen Bandpaare gelagert sind.An essential feature of the invention is that the support structures for each band of each pair of bands consist of plate or cuboid bearing blocks which are slidably mounted on horizontal guides and are connected in pairs to a pantograph lever system which can be driven via pneumatic cylinders in such a way that the bearing blocks are at their Adjustment movement with respect to the vertical displacement plane of the turning bar always have the same distances to this plane. Means are provided for setting the minimum distance between the bearing blocks on which the respective pairs of belts are mounted.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Patentansprüchen und aus der folgenden Beschreibung eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist.Further features and advantages of the invention emerge from the patent claims and from the following description of an exemplary embodiment which is illustrated in the drawing.

In allen Figuren sind einander entsprechende Bauteile mit denselben Bezugsziffern versehen.Corresponding components are provided with the same reference numbers in all the figures.

Wie sich vor allem aus den Figuren 1, 3 und 6 bis 10 ergibt, ist ein festes Gehäuse 1 vorgesehen, das zur Aufnahme und Lagerung der Wendeeinrichtung dient, deren Wendeorgane mit 2 bezeichnet sind.As can be seen above all from FIGS. 1, 3 and 6 to 10, a fixed housing 1 is provided which serves to accommodate and mount the turning device, the turning elements of which are designated by 2.

Die Wendeorgane 2 haben einen länglichen Wendestab 3, dessen freies Ende nach unten weist und der mittels einer kastenförmigen Führung 5 vor der Vorderwand 4 des Gehäuses 1 so gelagert ist, daß er zwischen einer oberen Endstellung (Figuren 1 und 6) einer unteren Endstellung (Figur 9) bewegt werden kann.The turning elements 2 have an elongated turning bar 3, the free end of which points downwards and which is mounted by means of a box-shaped guide 5 in front of the front wall 4 of the housing 1 in such a way that it moves between an upper end position (FIGS. 1 and 6) and a lower end position (FIG 9) can be moved.

Zur Längsverschiebung des Wendestabes 3 dient ein Pneumatikzylinder 6, der auf der kastenförmigen Führung 5 befestigt ist.A pneumatic cylinder 6, which is fastened on the box-shaped guide 5, serves for the longitudinal displacement of the turning bar 3.

Zur Gruppe der Wendeorgane 2 gehören zwei Paare endloser Bänder 7 und 8, die sich in vertikaler Richtung erstrecken, wobei das obere Paar mit 7 und das untere Paar mit 8 bezeichnet sind. Die ebenen Trume der Bänder laufen parallel zu der vertikalen Arbeitsebene, in der sich der Wendestab 3 bewegt. Zu beiden Seiten dieser Ebene sind die Bänder symmetrisch angeordnet und haben im "geöffneten" Zustand einen Abstand zu dieser Ebene, wenn das Gerät keine Funktion ausübt. Das obere Bandpaar 7 ist in einer solchen Höhe angeordnet, daß es zwischen seinen ebenen, einander gegenüberliegenden Trumen das untere Ende des Wendestabs 3 aufnimmt, wenn sich dieser in seiner obersten Stellung befindet.The group of turning elements 2 includes two pairs of endless belts 7 and 8, which extend in the vertical direction, the upper pair being designated 7 and the lower pair 8. The flat strands of the belts run parallel to the vertical working plane in which the turning bar 3 moves. The bands are arranged symmetrically on both sides of this level and are in the "open" state a distance from this level if the device is not performing any function. The upper pair of bands 7 is arranged at such a height that it receives the lower end of the turning bar 3 between its flat, opposite strands when it is in its uppermost position.

Die Bänder 7 und 8 sind vorzugsweise aus einem Elastomer-Kunststoff hergestellt, der mit in Längsrichtung verlaufenden, inneren Stahlfasern verstärkt ist. An ihrer Außenseite, die mit dem Strumpfgewebe in Berührung kommt, haben die Bänder V-förmige Quernuten, die sich über die gesamte Breite der Bänder erstrecken. Jedes Band 7 und 8 ist über zwei Rollen 9 und 10 geführt, die insbesondere in den Figuren 6 bis 10 gut zu erkennen sind und von denen eine Rolle angetrieben ist. Im Ausführungsbeispiel werden die oberen Rollen 9 für die oberen Bänder 7 sowie die unteren Rollen 8 für die unteren Bänder 10 angetrieben. Die Rollenpaare 9, 10, über welche die oberen Bänder 7 laufen, sind in je einem Lagerblock 11 bzw. 12 gelagert, der quaderoder plattenförmig ausgebildet ist. Die Lagerblöcke 11, 12 sind auf Querachsen 13 und 14 verschiebbar gelagert, die rechtwinklig zur vertikalen Arbeitsebene des Wendestabes 3 verlaufen, wobei die Lagerblöcke 11 und 12 von dieser Ebene gleiche Abstände haben und mittels eines Pneumatikzylinders 15 dieser Ebene gleichzeitig angenähert bzw. von dieser entfernt werden können. Der jeweils gewünschte Minimalabstand zwischen den beiden Lagerblöcken 11 und 12 und folglich auch zwischen den unmittelbar gegenüberliegenden Trumen der Bänder 7 kann über einen Stellknopf 16 mit Skalenring eingestellt werden. Hierzu wird auf Figur 4 hingewiesen, in der der Abstand zwischen dem oberen und dem unteren Bandpaar übermäßig groß eingezeichnet ist, um die Deutlichkeit der Darstellung zu erhöhen.The belts 7 and 8 are preferably made of an elastomer plastic which is reinforced with inner steel fibers running in the longitudinal direction. On the outside, which comes into contact with the hosiery fabric, the tapes have V-shaped transverse grooves which extend over the entire width of the tapes. Each belt 7 and 8 is guided over two rollers 9 and 10, which can be seen particularly well in FIGS. 6 to 10 and by which one roller is driven. In the exemplary embodiment, the upper rollers 9 for the upper belts 7 and the lower rollers 8 for the lower belts 10 are driven. The pairs of rollers 9, 10, over which the upper belts 7 run, are each mounted in a bearing block 11 or 12, which is cuboid or plate-shaped. The bearing blocks 11, 12 are slidably mounted on transverse axes 13 and 14 which run at right angles to the vertical working plane of the turning bar 3, the bearing blocks 11 and 12 being at the same distances from this plane and at the same time being approximated or removed from this plane by means of a pneumatic cylinder 15 can be. The respectively desired minimum distance between the two bearing blocks 11 and 12 and consequently also between the directly opposite strands of the belts 7 can be set using an adjusting knob 16 with a scale ring. For this purpose, reference is made to FIG. 4, in which the distance between the upper and the lower pair of bands is drawn in excessively large in order to increase the clarity of the representation.

Zum Antrieb der beiden oberen Rollen 9, über welche die beiden Bänder 7 geführt sind, dient ein Motor 17, welcher im oberen Teil des Gehäuses 1 untergebracht ist. Dieser treibt über Riemen 18, 19 und 20 sowie Zahnräder 21 und 22 die Rollen 9 an. Der entsprechende Antrieb für die Rollen 10, über welche die beiden unteren Bänder 8 laufen, ist in analoger Weise aufgebaut. Der einzige Unterschied besteht darin, daß die Anordnung spiegelsymmetrisch zu einer horizontalen Ebene ist. Aus diesen Gründen wird auf eine nochmalige Beschreibung verzichtet, wobei der Hinweis genügt, daß die entsprechenden Bauteile dieselben Bezugsziffern mit Hinzufügung eines hochgestellten Striches haben.A motor 17, which is accommodated in the upper part of the housing 1, serves to drive the two upper rollers 9, over which the two belts 7 are guided. This drives the rollers 9 via belts 18, 19 and 20 as well as gear wheels 21 and 22. The corresponding drive for the rollers 10, over which the two lower belts 8 run, is constructed in an analogous manner. The only difference is that the arrangement is mirror-symmetrical to a horizontal plane. For these reasons, a repeated description is omitted, whereby it is sufficient to note that the corresponding components have the same reference numbers with the addition of a prime.

Die Querachsen 13, 14 sowie 13', 14' sind im Gehäuse 1 über C-förmige Profilkörper 23, 24 bzw. 23', 24' fixiert. Um sicherzustellen, daß sich die Lagerblöcke 11 und 12 bzw. 11' und 12' unter dem Antrieb des jeweiligen Pneumatikzylinders 15 bzw. 15' im gleichen Maß einander annähern bzw. sich voneinander entfernen, ist jeweils ein Hebelsystem 25 bzw. 25' vorgesehen, das im wesentlichen als Parallelogrammlenker wirkt und mit den zugehörigen Lagerblöcken 11 und 12 bzw. 11' und 12' verbunden ist. Figur 4 zeigt das den oberen Lagerblöcken 11 und 12 zugeordnete Hebelsystem 25, das an einer festen Tragkonsole 25a angelenkt ist.The transverse axes 13, 14 and 13 ', 14' are fixed in the housing 1 via C-shaped profile bodies 23, 24 and 23 ', 24'. To ensure that the bearing blocks 11 and 12 or 11 'and 12' under the drive of the respective pneumatic cylinder 15 or 15 'approach or move away from each other to the same extent, a lever system 25 or 25' is provided, which essentially acts as a parallelogram link and is connected to the associated bearing blocks 11 and 12 or 11 'and 12'. FIG. 4 shows the lever system 25 assigned to the upper bearing blocks 11 and 12, which is articulated on a fixed support bracket 25a.

Der Stellknopf 16 hat eine nockenförmige Stirnfläche 16a mit Einkerbungen, in die ein Finger 24a einrasten kann, der am Profilkörper 24 befestigt ist, welcher seinerseits im Gehäuse 1 fest angebracht ist. Wenn der Stellknopf 16 im Uhrzeigersinn gemäß Pfeil 16b gedreht wird, kann die Querachse 14 gegen die Wirkung einer Feder 23a verstellt werden, die ihrerseits versucht, die Querachse 14 nach rechts zu verschieben (vgl. Figur 4). Diese Bewegung wird über eine Nutmutter 14 (in Figur 4 ist die Nutmutter 14'a für das untere System zum seitlichen Verschieben der Bänder 8 dargestellt) auf den Lagerblock 11 übertragen.The adjusting knob 16 has a cam-shaped end face 16a with notches into which a finger 24a can snap, which is attached to the profile body 24, which in turn is fixedly attached in the housing 1. If the adjusting knob 16 is turned clockwise according to arrow 16b, the transverse axis 14 can be adjusted against the action of a spring 23a, which in turn tries to shift the transverse axis 14 to the right (see FIG. 4). This movement is transmitted to the bearing block 11 via a lock nut 14 (the lock nut 14'a for the lower system for laterally displacing the belts 8 is shown in FIG. 4).

Die Übergabeeinrichtung zur Abnahme eines zu wendenden Strumpfes von der Kettelmaschine und zur Weiterleitung an die Wendeorgane ist insbesondere in den Figuren 1, 2, 3 und 11 gezeigt.The transfer device for removing a stocking to be turned from the linking machine and for forwarding it to the turning organs is shown in particular in FIGS. 1, 2, 3 and 11.

Diese Übergabeeinrichtung hat einen zangenförmigen Greifer 26 mit zwei Backen 27 und 28, die über einen Drehzapfen 29 schwenkbar zueinander gelagert sind. Der Drehzapfen 29 liegt in einer horizontalen Ebene und erstreckt sich in Längsrichtung des Greifers 26, so daß auch die einander gegenüberliegenden Greifränder 27' und 28' der Backen in einer horizontalen Ebene liegen.This transfer device has a pincer-shaped gripper 26 with two jaws 27 and 28 which are pivotally mounted to one another via a pivot pin 29. The pivot 29 lies in a horizontal plane and extends in the longitudinal direction of the gripper 26, so that the mutually opposite gripping edges 27 'and 28' of the jaws lie in a horizontal plane.

Der Greifer 26 wird normalerweise durch eine Feder 30 in seiner geschlossenen Stellung gehalten. Diese Feder 30 ist in einem Bereich oberhalb des Drehzapfens 29 zwischen die beiden Backen 27 und 28 eingesetzt. Unterhalb der beiden Backen 27 und 28 befindet sich ein Pneumatikzylinder 31, der zum Öffnen des Greifers 26 dient.The gripper 26 is normally held in its closed position by a spring 30. This spring 30 is inserted in an area above the pivot 29 between the two jaws 27 and 28. Below the two jaws 27 and 28 there is a pneumatic cylinder 31, which is used to open the gripper 26.

In der in den Figuren 1 bis 10 gezeigten Ausführungsform ist die Backe 27 des Greifers 26 fest an einem Tragarm 32 angebracht, der seitlich vom unteren Ende eines Schlittens 33 absteht. Der Schlitten 33 ist auf zwei horizontalen Längsführungselementen 34 und 35 verschiebbar gelagert, die parallel zu der vertikalen Arbeitsebene verlaufen, in der sich der Wendestab 3 bewegt. Die Längsführungselemente 34 und 35 sind in einer Konsole 36 angebracht, die seitlich von den Bandpaaren 7 und 8 an der Vorderwand 4 des Gehäuses 1 befestigt ist. Im Gehäuse 1 ist ein Pneumatikzylinder 37 untergebracht, der den Schlitten 33 auf den Längsführungselementen 34 und 35 so verschiebt, daß der Greifer 26 auf einer vorbestimmten, geradlinigen Bahn zwischen einer bezüglich der Wendeorgane 3, 7, 8 äußeren Stellung und einer inneren Stellung verschoben wird, in der er sich zwischen den oberen Bändern 7 befindet, wobei die einander gegenüberliegenden, zusammenwirkenden Greifränder 27' und 28' der beiden Backen 27 und 28 parallel zur vertikalen Arbeitsebene des Wendestabes 3 liegen. Die Teile sind so dimensioniert, daß in der zuletzt genannten Stellung der Greifrand 27' der am Tragarm 32 befestigten Backe 27 etwas über diese vertikale Arbeitsebene hinausragt, und zwar in eine von der Konsole 36 wegweisenden Richtung.In the embodiment shown in Figures 1 to 10, the jaw 27 of the gripper 26 is fixedly attached to a support arm 32 which projects laterally from the lower end of a carriage 33. The slide 33 is slidably mounted on two horizontal longitudinal guide elements 34 and 35 which run parallel to the vertical working plane in which the turning bar 3 moves. The longitudinal guide elements 34 and 35 are attached in a bracket 36, which is attached laterally by the pairs of bands 7 and 8 to the front wall 4 of the housing 1. In the housing 1, a pneumatic cylinder 37 is housed, which moves the slide 33 on the longitudinal guide elements 34 and 35 so that the gripper 26 is displaced on a predetermined, linear path between an outer position with respect to the turning elements 3, 7, 8 and an inner position , in which it is located between the upper bands 7, the mutually opposing, cooperating gripping edges 27 'and 28' of the two jaws 27 and 28 lying parallel to the vertical working plane of the turning bar 3. The parts are dimensioned such that, in the last-mentioned position, the gripping edge 27 'of the jaw 27 fastened to the support arm 32 projects somewhat beyond this vertical working plane, in a direction pointing away from the console 36.

Mit 38 und 39 sind Magnetsensoren bezeichnet, die aktiviert werden, wenn der Kolben des Pneumatikzylinders 37 und mit diesem der Schlitten 33 in der jeweiligen Endstellung sind, in der der Greifer 26 die zuvor genannte innere bzw. äußere Stellung einnimmt.38 and 39 denote magnetic sensors which are activated when the piston of the pneumatic cylinder 37 and with this the slide 33 are in the respective end position, in which the gripper 26 assumes the aforementioned inner and outer position.

Wenn sich der Greifer 26 in der äußeren Stellung befindet, steht er über der Abgabezone 40 der geradlinig ausgebildeten Kettelmaschine 41 (vgl. Figuren 1 und 3). Die Strümpfe mit den bereits angenähten Spitzen, die fertig beschnitten bzw. vernäht sind, werden in die Abgabezone 40 durch ein Transportband 42 gebracht, das mit einem Schlitten 42a zusammenarbeitet, der durch zwei nicht gezeigte Federn gegen das Transportband 42 gedrückt wird. Um den Schlitten 42a von dem Transportband 42 zu entfernen, ist ein Pneumatikzylinder 42b vorgesehen. Der Greifer 26 kommt geöffnet in dieser Position an, und der vom Transportband 42 in Richtung auf das Wendegerät zugeführte Strumpf bleibt stehen, sobald er bezüglich des Greifers 26 die richtige Stellung erreicht hat.When the gripper 26 is in the outer position, it stands above the delivery zone 40 of the straight-line chaining machine 41 (cf. FIGS. 1 and 3). The stockings with the already sewn tips, which are already trimmed or sewn, are brought into the delivery zone 40 by a conveyor belt 42, which works together with a carriage 42a, which is pressed against the conveyor belt 42 by two springs, not shown. In order to remove the carriage 42a from the conveyor belt 42, a pneumatic cylinder 42b is provided. The gripper 26 arrives open in this position, and the stocking fed by the conveyor belt 42 in the direction of the turning device stops as soon as it has reached the correct position with respect to the gripper 26.

Unter "richtiger Stellung" wird diejenige Lage verstanden, in der sichergestellt ist, daß nach dem Schließen des Greifers 26 und dessen Verschiebung in Richtung der "inneren Stellung" sich der in Figur 2 gezeigte Sack S, der in der Spitze des Strumpfes neben dem Nahtbereich gebildet ist und vom Greifer noch geschlossen gehalten wird, bezüglich des unteren Endes des Wendestabes 3 zentriert ist (die vertikale Längsmittelebene des Wendestabes 3 fällt mit der vertikalen Längsmittelebene der beiden Bandpaare 7 und 8 zusammen). Diese Bedingung muß erfüllt sein, um anschließend den Strumpf fehler- und störungsfrei wenden zu können."Correct position" means the position in which it is ensured that after closing the gripper 26 and moving it in the direction of the "inner position" there is the sack S shown in FIG. 2, which is in the top of the stocking next to the seam area is formed and is still held closed by the gripper, is centered with respect to the lower end of the turning bar 3 (the vertical longitudinal center plane of the turning bar 3 coincides with the vertical longitudinal center plane of the two pairs of belts 7 and 8). This condition must be met in order to be able to turn the stocking without any errors or faults.

Mit Hilfe der Photozelle 43, die in der Abgabezone 40 der Kettelmaschine 41 unter dem Schlitten 42a angebracht ist, wird diese "richtige Stellung" bestimmt. Die Photozelle 43 wird nämlich aktiviert, sobald sie vom Gewebe des Strumpfes 44 verdunkelt wird (vgl. Figuren 1 und 3). Um die Einrichtung an Strümpfe unterschiedlicher Größen anpassen zu können, ist die Photozelle 43 an einer Platte 45 angebracht, deren Stellung in Richtung der Verschiebung des Greifers 26 bezüglich der Abgabezone 40 der Kettelmaschine 41 eingestellt werden kann.This "correct position" is determined with the aid of the photocell 43, which is attached in the delivery zone 40 of the linking machine 41 under the carriage 42a. The photocell 43 is activated as soon as it is darkened by the fabric of the stocking 44 (see FIGS. 1 and 3). In order to be able to adapt the device to stockings of different sizes, the photocell 43 is attached to a plate 45, the position of which can be adjusted in the direction of the displacement of the gripper 26 with respect to the delivery zone 40 of the warping machine 41.

Vor der Vorderwand 4 des Gehäuses 1 befindet sich mit einem Abstand unterhalb der beiden unteren Bänder 7 eine Stabilisiereinrichtung, die die Aufgabe hat, die ausgerichtete Lage des Strumpfes während des Wendevorganges zu kontrollieren. Sie hat zwei Kämme 46, die untereinander gleich ausgebildet und symmetrisch zu beiden Seiten der vertikalen Arbeitsebene des Wendestabes 3 angeordnet sind. Sie erstrecken sich rechtwinklig zur Vorderwand 4 des Gehäuses 1 und sind am oberen Ende zweier Tragarme 47 befestigt, die ebenfalls untereinander gleich und zu der genannten, vertikalen Arbeitsebene symmetrisch angeordnet sind. Die beiden Tragarme 47 sind nach oben hin etwas gespreizt, und ihre unteren Enden sind um je eine Drehachse 48 schwenkbar gelagert, die rechtwinklig zur Vorderwand 4 verläuft. Um die Kämme 46 auf die genannte, vertikale Arbeitsebene hin zu bewegen, wird ein in Figur 5 gezeigter Pneumatikzylinder 49, 50 betätigt, der im Gehäuse 1 untergebracht ist und die beiden Tragarme 47 in der gewünschten Richtung um ihre jeweilige Drehachse 48 schwenkt.In front of the front wall 4 of the housing 1, at a distance below the two lower bands 7, there is a stabilizing device which has the task of checking the aligned position of the stocking during the turning process. It has two combs 46 which are identical to one another and are arranged symmetrically on both sides of the vertical working plane of the turning bar 3. They extend at right angles to the front wall 4 of the housing 1 and are fastened to the upper end of two support arms 47, which are likewise identical to one another and are arranged symmetrically with respect to the vertical working plane mentioned. The two support arms 47 are slightly spread upwards, and their lower ends are each pivotable about an axis of rotation 48 which extends at right angles to the front wall 4. In order to move the combs 46 towards the vertical working plane mentioned, a pneumatic cylinder 49, 50 shown in FIG. 5 is actuated, which is housed in the housing 1 and pivots the two support arms 47 about their respective axis of rotation 48 in the desired direction.

Der kleinste Abstand zwischen den beiden Kämmen 46 kann über eine Einrichtung eingestellt werden, die ähnlich aufgebaut ist wie diejenige, mit deren Hilfe der Minimalabstand zwischen den Bändern 7 und 8 eingestellt wird. Figur 5 zeigt, daß diese Einrichtung eine Stange 51 aufweist, an der ein Stellknopf 52 angebracht ist, der außerhalb des Gehäuses 1 liegt und stirnseitig als Nocken 53 mit Einkerbungen ausgebildet ist, in die ein Finger 54 einrasten kann, der am Gehäuse 1 befestigt ist. Eine Feder 55 drückt die Stange 51 in Richtung des linken Randes der Figur 5. Eine auf der Stange 51 befestigte Nutmutter 56 wirkt auf den rechten Tragarm 47 in dem Sinn ein, daß sie versucht, ihn vom linken Tragarm 47 zu entfernen. Auf diesen wird die Schwenkbewegung über Zahnsektoren 57 übertragen, die auf den Drehachsen 48 gelagert sind.The smallest distance between the two combs 46 can be set using a device which is constructed similarly to that with the aid of which the minimum distance between the bands 7 and 8 is set. Figure 5 shows that this device has a rod 51, on which an adjusting button 52 is attached, which is located outside the housing 1 and is formed on the end face as a cam 53 with notches in which a finger 54 can snap, which is attached to the housing 1. A spring 55 pushes the rod 51 towards the left edge of FIG. 5. A lock nut 56 attached to the rod 51 acts on the right arm 47 in the sense that it tries to remove it from the left arm 47. The pivoting movement is transmitted to these via toothed sectors 57, which are mounted on the axes of rotation 48.

Zwischen den Kämmen 46 und den beiden unteren Bändern 8 befindet sich eine weitere Photozelle 58, die auf einer Seite der vertikalen Längsmittelebene des Wendestabes 3 so angebracht ist, daß ihr horizontaler Lichtstrahl parallel zur Vorderwand 4 des Gehäuses 1 ausgerichtet ist.Between the combs 46 and the two lower bands 8 there is a further photocell 58 which is mounted on one side of the vertical longitudinal center plane of the turning bar 3 in such a way that its horizontal light beam is aligned parallel to the front wall 4 of the housing 1.

Schließlich ist das Strumpfwendegerät mit einer programmierbaren Steuereinheit 59 ausgerüstet, welche mit den Magnetsensoren 38 und 39, mit den Photozellen 43 und 58, mit den Motoren 17 und 17' sowie mit allen zuvor erläuterten Pneumatikzylindern verbunden ist. Mit Hilfe des Programms dieser Steuereinheit 59 können die Funktionen dieser Elemente koordiniert werden, um die Wendezyklen für die Strümpfe, die von der Kettelmaschine kommen, reibungslos durchführen zu können.Finally, the hosiery turning device is equipped with a programmable control unit 59 which is connected to the magnetic sensors 38 and 39, to the photocells 43 and 58, to the motors 17 and 17 'and to all the pneumatic cylinders explained above. With the help of the program of this control unit 59, the functions of these elements can be coordinated in order to be able to carry out the turning cycles for the stockings coming from the warping machine smoothly.

Nachstehend wird die Betriebsweise des Strumpfwendegerätes anhand der Figuren 6 bis 10 erläutert.The operation of the hosiery turning device is explained below with reference to FIGS. 6 to 10.

Bevor ein Wendezyklus beginnt, befindet sich das Strumpfwendegerät gemäß der Erfindung in der Stellung der Figur 1. Die Spitze bzw. das Fußende des Strumpfes 44, der durch das angenähnte Fußteil bereits geschlossen ist, wird zwischen die beiden Backen 27, 28 des Greifers 26 gebracht. Sobald das obere Ende des Strumpfes 44 seine zentrierte Stellung bezüglich der Breite der Backen des Greifers 46 erreicht hat, verdunkelt der Strumpf 44 die Photozelle 43, wodurch über die Steuereinheit 59 die folgenden Arbeitsgänge in der angegebenen Reihenfolge ablaufen: Schließen des Greifers 26, Entfernung des Schlittens 42a vom Transportband 42 und schließlich Verschiebung des Schlittens 33 mit dem Greifer 26 in Richtung auf die Wendeorgane 2. Die Verschiebung des Schlittens 33 ist beendet, sobald sich der Greifer 26 zwischen den beiden oberen Bändern 7 befindet, wobei der Strumpf 44 zwischen den beiden unteren Bändern 8 hängt und die Kämme 46 eine geöffnete Stellung einnehmen (vgl. Figur 6). Aufgrund der Tatsache, daß der Sack S, der neben der vom Greifer 26 erfaßten Spitze des Strumpfes 44 liegt, d.h. seitlich neben der vertikalen Arbeitsebene des Wendestabs 3, und aufgrund der zentrierten Stellung der Spitze bezüglich der Backen 27 und 28 befindet sich der Sack S genau unter dem unteren Ende des Wendestabes 3. Der Strumpf 44 verdunkelt die Photozelle 58, die in dieser Phase inaktiv ist.Before a turning cycle begins, the hosiery turning device according to the invention is in the position of FIG. 1. The tip or foot end of the stocking 44, which is already closed by the sewn-on foot part, is brought between the two jaws 27, 28 of the gripper 26 . As soon as the upper end of the stocking 44 has reached its centered position with respect to the width of the jaws of the gripper 46, the stocking 44 darkens the photocell 43, as a result of which the following operations take place via the control unit 59 in the specified sequence: closing the gripper 26, removing the Slide 42a from Conveyor belt 42 and finally displacement of the carriage 33 with the gripper 26 in the direction of the turning elements 2. The displacement of the carriage 33 is complete as soon as the gripper 26 is between the two upper belts 7, the stocking 44 between the two lower belts 8 hangs and the combs 46 assume an open position (see FIG. 6). Due to the fact that the sack S, which lies next to the tip of the stocking 44 gripped by the gripper 26, ie laterally next to the vertical working plane of the turning bar 3, and because of the centered position of the tip with respect to the jaws 27 and 28, the sack S is located just below the lower end of the turning bar 3. The stocking 44 darkens the photocell 58, which is inactive in this phase.

In dieser Stellung befindet sich der Kolben des Pneumatikzylinders 37 zur Verschiebung des Schlittens 33 dicht neben dem Magnetsensor 38, der dadurch aktiviert wird und einen Steuerbefehl an die Steuereinheit 59 leitet. Dadurch werden die beiden unteren Bänder 8 sowie die Kämme 46 der Stabilisierungseinrichtung "geschlossen", während sich der Greifer 26 öffnet und der Schlitten 33 in seine Ausgangsstellung zurückgefahren wird, in der der jetzt wieder geöffnete Greifer 26 die oben erläuterte, äußere Stellung einnimmt. In dieser Stellung ist der Greifer bereit, den nächsten Strumpf aufzunehmen, dessen Spitze auf der Kettelmaschine 41 zugenäht worden ist. Die nun erreichte Stellung der Wendeorgane (Wendestab 3, Bandpaar 7 und 8 sowie Kämme 46) ist in Figur 7 dargestellt. Durch die Rückführung des Schlittens 33 zur Kettelmaschine 41 hin gibt der Magnetsensor 39 einen Impuls an die Steuereinheit 59 ab, was zur Folge hat, daß die beiden oberen Bänder 7 "geschlossen" und sowohl die oberen Bänder 7 als auch die unteren Bänder 8 in einer solchen Drehrichtung angetrieben werden, daß ihre unmittelbar einander gegenüberliegenden Trume nach oben laufen. Durch den Steuerbefehl wird außerdem die Photozelle 58 aktiviert und der Wendestab 3 nach unten verschoben. Dabei wird der zwischen den Kämmen 46 gehaltene Strumpf nach oben und auf den Wendestab 3 geschoben, wobei er gemäß Figur 8 gewendet wird.In this position, the piston of the pneumatic cylinder 37 for displacing the slide 33 is located close to the magnetic sensor 38, which is thereby activated and forwards a control command to the control unit 59. As a result, the two lower bands 8 and the combs 46 of the stabilizing device are “closed” while the gripper 26 opens and the slide 33 is moved back to its starting position, in which the gripper 26, which is now open again, assumes the external position explained above. In this position, the gripper is ready to pick up the next stocking, the tip of which has been sewn onto the linking machine 41. The now reached position of the turning elements (turning bar 3, pair of bands 7 and 8 and combs 46) is shown in FIG. By returning the carriage 33 to the linking machine 41, the magnetic sensor 39 emits a pulse to the control unit 59, which has the consequence that the two upper belts 7 are "closed" and both the upper belts 7 and the lower belts 8 in one are driven in such a direction that their directly opposite dreams run upwards. The control command also activates the photocell 58 and moves the turning bar 3 downward. The stocking held between the combs 46 is pushed upwards and onto the turning bar 3, wherein it is turned according to Figure 8.

In dieser Phase sorgt die Stabilisierungseinrichtung mit den Kämmen 46 dafür, daß der Strumpf während seiner nach oben gerichteten Bewegung gespannt bleibt, so daß er gestreckt wird, falls er sich drehen oder abknicken würde, so daß auf diese Weise ein Verklemmen oder Verkanten des Wendestabes 3 im Hohlraum der Ferse oder im verdoppelten, elastischen, freien Rand des Beinteils des Strumpfes verhindert wird.In this phase, the stabilizing device with the combs 46 ensures that the stocking remains tensioned during its upward movement, so that it is stretched if it would twist or kink, so that the turning bar 3 is jammed or tilted is prevented in the cavity of the heel or in the doubled, elastic, free edge of the leg part of the stocking.

Wenn der Wendestab 3 seine in Figur 9 gezeigte, unterste Stellung erreicht hat, drehen sich die Bänder 7 und 8 weiter in Richtung der eingezeichneten Pfeile, so daß der Strumpf auf dem Wendestab 3 nach oben geschoben wird. Sobald jedoch der obere Rand des Beinteils des Strumpfes die Photozelle 58 nicht mehr verdunkelt, gibt diese an die Steuereinheit 59 einen Befehl ab, wodurch die folgenden Funktionen in Gang gesetzt werden.When the turning bar 3 has reached its lowest position shown in FIG. 9, the belts 7 and 8 continue to rotate in the direction of the arrows shown, so that the stocking on the turning bar 3 is pushed upwards. However, as soon as the upper edge of the leg part of the stocking no longer darkens the photocell 58, it issues a command to the control unit 59, whereby the following functions are started.

Nachdem die Kämme 46 geöffnet worden sind, wird mit einer geringen Verzögerung die Drehbewegung der oberen Bänder 7 angehalten, damit der obere Rand des Beinteils des Strumpfes über die oberen Bänder 7 hinausgeschoben wird. Durch den Steuerbefehl wird außerdem der Wendestab 3 nach oben bewegt, während die Drehrichtung der unteren Bänder 8 umgekehrt wird, um den Strumpf nach unten abzuziehen.After the combs 46 have been opened, the rotational movement of the upper bands 7 is stopped with a slight delay so that the upper edge of the leg part of the stocking is pushed over the upper bands 7. The control command also moves the turning bar 3 upwards, while the direction of rotation of the lower belts 8 is reversed in order to pull the stocking downwards.

Während der Strumpf vom Wendestab 3 abgezogen wird, der sich dabei nach oben bewegt, wird die Photozelle 58 erneut durch den sich nach unten bewegenden Strumpf 44 verdunkelt (vgl. Figur 10), ohne daß dadurch jedoch die unteren Bänder 8 angehalten werden, bis die Verdunklung der Photozelle 58 erneut unterbrochen wird.While the stocking is withdrawn from the turning bar 3, which moves upward, the photocell 58 is darkened again by the stocking 44 moving downward (see FIG. 10), without however the lower straps 8 being stopped until the Darkening of the photocell 58 is interrupted again.

Das hat zur Folge, daß die Bewegung der unteren Bänder 8 angehalten wird, wobei sich diese und die oberen Bänder 7 gleichzeitig in ihre geöffnete Stellung bewegen, so daß ein neuer Strumpf für den Beginn eines folgenden Wendezyklus eingeführt werden kann.As a result, the movement of the lower belts 8 is stopped, and these and the upper belts 7 move simultaneously into their open position, so that a new stocking can be introduced for the start of a subsequent turning cycle.

Es ist festzustellen, daß während der beschriebenen Arbeitsabläufe die Drehung der oberen Bänder 7 die unteren Bänder 8 dabei unterstützt, den Strumpf auf den Wendestab 3 aufzuziehen, und daß der nachfolgende Stillstand der Bänder 7 dazu dient, den doppelt gelegten Teil des Strumpfes zu halten, der sich über den beiden oberen Bändern 7 befindet, wodurch das Abziehen des fehlerfrei gewendeten Strumpfes erleichtert wird.It should be noted that during the workflows described, the rotation of the upper straps 7 assists the lower straps 8 in pulling the stocking onto the turning bar 3 and that the subsequent stoppage of the straps 7 serves to hold the doubled part of the stocking, which is located above the two upper straps 7, which makes it easier to pull off the stocking which has been turned without errors.

Die Vorteile des Strumpfwendegerätes gemäß der Erfindung sind aufgrund der besonderen Eigenschaften zahlreich und von besonderer, praktischer Bedeutung. Da der Durchmesser der Rollen, über welche die Bänder laufen, verhältnismäßig klein sein kann (z.B. 34 mm), steht der zwischen den unteren Bändern 8 eingeklemmte Strumpf nur wenig über den oberen Rand der Klemmzone hervor (in der Praxis etwa 22 mm), so daß keine Gefahr besteht, daß er sich zur Seite neigen kann, weshalb der nach unten vorrückende Wendestab 3 sicher in den Sack eintritt, der sich auf einer Seite der angenähten Spitze des Strumpfes befindet.The advantages of the hosiery turning device according to the invention are numerous due to the special properties and of particular practical importance. Since the diameter of the rolls over which the belts run can be relatively small (for example 34 mm), the stocking clamped between the lower belts 8 protrudes only slightly above the upper edge of the clamping zone (in practice about 22 mm), so that there is no danger that it can tilt to the side, which is why the downward turning turning rod 3 safely enters the sack, which is located on one side of the sewn-on top of the stocking.

Aufgrund der Tatsache, daß sich die Berührungszone zwischen den beiden Greifrändern 27', 28' der Backen des geschlossenen Greifers 26 auf einer Seite der vertikalen Arbeitsebene des Wendestabes 3 befindet (im allgemeinen 5 mm seitlich versetzt zu dieser Ebene), ist sichergestellt, daß der Wendestab 3 immer exakt in diesen Sack eintritt, auch dann, wenn das Wendegerät mit einer geradlinigen Kettelmaschine kombiniert ist, wobei dann der Sack von dem Bandförderer gehalten wird, bis der Greifer die genähte Spitze des Strumpfes erfaßt.Due to the fact that the contact zone between the two gripping edges 27 ', 28' of the jaws of the closed gripper 26 is on one side of the vertical working plane of the turning bar 3 (generally 5 mm laterally offset from this plane), it is ensured that the Turning bar 3 always enters this sack exactly, even if the turning device is combined with a straight-line chaining machine, the sack then being held by the belt conveyor until the gripper grasps the sewn tip of the stocking.

Durch den Einsatz von Bändern wird deren Schließkraft über eine große Fläche verteilt, so daß der auf den Strumpf ausgeübte Druck verhältnismäßig niedrig ist, was zur Folge hat, daß selbst sehr empfindliche, feine Strümpfe durch die Bänder nicht beschädigt werden können, welche ihrerseits eine vernachlässigbare Abnutzung erfahren.Through the use of tapes, the closing force is distributed over a large area, so that the pressure exerted on the stocking is relatively low, with the result that even very sensitive, fine stockings cannot be damaged by the tapes, which in turn can be neglected Experience wear.

Von besonderem Vorteil ist auch die Tatsache, daß die Bänder über die gesamte Breite verlaufende, V-förmige Querrillen haben, so daß auch Strümpfe mit sehr losen Maschen beim Wenden nicht beschädigt werden, da die durchlaufenden Quernuten die lose gewirkten Fäden weder erfassen noch ausziehen können.Another particular advantage is the fact that the tapes have V-shaped transverse grooves running across their entire width, so that stockings with very loose stitches are not damaged when turning, since the continuous transverse grooves can neither catch nor pull out the loosely knitted threads .

Die für einen Wendevorgang erforderliche Zeit ist verhältnismäßig kurz, weil der Wendestab 3 während seiner Bewegung zwischen der oberen und der unteren Endstellung nicht stehenbleibt. Dadurch, daß die unteren Bänder 8, die am Wendevorgang beteiligt sind, auch dazu dienen, den Strumpf nach unten abzuziehen und dazu ihre Drehrichtung umkehren, wird sichergestellt, daß keine Reibung auf den Strumpf einwirkt, was vor allem Beschädigungen von Frotteestrümpfen ausschließt.The time required for a turning process is relatively short because the turning bar 3 does not stop during its movement between the upper and lower end positions. The fact that the lower straps 8, which are involved in the turning process, also serve to pull the stocking down and to reverse their direction of rotation, ensures that no friction acts on the stocking, which above all prevents damage to terry socks.

Bei seiner Abwärtsbewegung hält der Wendestab 3 in einer solchen Stellung an, daß sich sein unteres Ende unterhalb der unteren Bänder 8 befindet. Das hat den Vorteil, daß die unteren Bänder 8 nicht auf den Bereich der genähten Spitze des Strumpfes einwirken, sondern lediglich auf den Fußbereich. In diesem ist nämlich die Richtung der Maschen entgegengesetzt zu derjenigen in der Spitze des Strumpfes, so daß im darunterliegenden Teil die Gefahr vermieden wird, daß die Maschen eines aus Frottee bestehenden Strumpfes aufgezogen werden.During its downward movement, the turning bar 3 stops in such a position that its lower end is below the lower bands 8. This has the advantage that the lower straps 8 do not act on the area of the sewn tip of the stocking, but only on the foot area. This is because the direction of the stitches is opposite to that in the top of the stocking, so that in the part underneath the risk of the stitches of a stocking consisting of terry stocking being avoided.

Von besonderem Vorteil ist es, daß beide Bänder jedes Paares angetrieben werden, weil dadurch jede relative Höhenverschiebung der Strumpfteile vermieden wird, die sich zu beiden Seiten des Wendestabes 3 befinden.It is particularly advantageous that both belts of each pair are driven because this avoids any relative height shift of the stocking parts which are located on both sides of the turning bar 3.

Die feste Verbindung zwischen den Kämmen 46 und ihren Tragarmen 47 gestattet es, den Strumpf immer gut gespannt und während des Wendevorganges exakt ausgerichtet zu halten, wobei die Gefahr vermieden wird, daß sich der Wendestab 3 in der Ferse oder im oberen Rand des Beinteils des Strumpfes verkantet oder verklemmt, wenn die Strümpfe doppelt elastisch sind bzw. der obere Rand doppelt ist. Gleichzeitig erleichtert der Antrieb der die Kämme tragenden Tragarme 47 mittels eines Pneumatikzylinders die Anpassung des Strumpfwendegerätes an Strümpfe unterschiedlicher Dicken.The firm connection between the combs 46 and their support arms 47 makes it possible to keep the stocking always taut and precisely aligned during the turning process, avoiding the risk of the turning bar 3 being in the heel or in the upper edge of the leg part of the stocking canted or jammed if the stockings are double elastic or the upper edge is double. At the same time, driving the support arms 47 carrying the combs by means of a pneumatic cylinder facilitates the adaptation of the hosiery turning device to stockings of different thicknesses.

Das Strumpfwendegerät gemäß der Erfindung kann auch zum Wenden von Kinderstrümpfen eingesetzt werden, sofern diese eine Länge haben, die von den Kämmen 46 gehalten werden kann. Das Gerät kann jedoch leicht an Strümpfe kleiner Größen bis zu einer Mindestlänge von 18 cm angepaßt werden. Hierzu genügt es nämlich, die Photozelle 58 abzunehmen und die Steuereinheit so zu programmieren, daß die Zeit für einen Wendevorgang fest vorgegeben wird, wozu der Abwärtshub des Wendestabes 3 entsprechend verringert und die Kämme 46 den unteren Bändern 8 angenähert werden.The stocking turning device according to the invention can also be used for turning children's stockings, provided that they have a length that can be held by the combs 46. However, the device can easily be adapted to stockings of small sizes up to a minimum length of 18 cm. To do this, it is sufficient to remove the photocell 58 and program the control unit so that the time for a turning process is fixed, for which purpose the downward stroke of the turning bar 3 is reduced accordingly and the combs 46 are brought closer to the lower bands 8.

Das Abziehen des bereits gewendeten Strumpfes nach unten wird dadurch begünstigt, daß die oberen Bänder 7, die sich zu Beginn des Zyklus in derselben Richtung drehen wie die unteren Bänder 8, während der Abzugsphase angehalten werden und dadurch die Abwärtsbewegung des Strumpfes leicht bremsen.The pulling down of the stocking which has already been turned over is promoted by the fact that the upper belts 7, which rotate in the same direction as the lower belts 8 at the beginning of the cycle, are stopped during the pulling-off phase and thereby slightly brake the downward movement of the stocking.

Die oberen Bänder 7 und die unteren Bänder 8 werden simultan in Richtung auf die vertikale Arbeitsebene des Wendestabes 3 bewegt und von dieser Ebene zurückgezogen, wofür jedes Bandpaar mit einem Pneumatikzylinder verbunden ist. Mit dieser Maßnahme kann der Mindestabstand der Bänder von der genannten Ebene leicht und sehr genau eingestellt werden, so daß das Strumpfwendegerät einfach und exakt an die Behandlung von Strümpfen unterschiedlicher Dicken angepaßt werden kann, ohne daß hierzu besonders ausgebildetes Personal erforderlich ist. Der für diese Einstellung erforderliche Arbeitsvorgang ist so einfach, daß er von jeder Bedienungsperson ausgeführt werden kann, die an der Kettelmaschine und dem Strumpfwendegerät tätig ist. Es genügt nämlich, für jedes Bandpaar lediglich den entsprechenden Stellknopf zu verdrehen, der mit Skaleneinteilung versehen und leicht zugänglich ist. Auf diese Weise kann der kleinste Abstand der Bänder von der vertikalen Arbeitsebene des Wendestabes 3 mikrometergenau eingestellt werden.The upper belts 7 and the lower belts 8 are simultaneously moved in the direction of the vertical working plane of the turning bar 3 and withdrawn from this plane, for which each pair of belts is connected to a pneumatic cylinder. With this measure, the minimum distance of the bands from the above-mentioned level can be adjusted easily and very precisely, so that the hosiery turning device can be easily and precisely adapted to the treatment of stockings of different thicknesses without the need for specially trained personnel. The procedure required for this adjustment is so simple that it can be carried out by any operator who works on the linking machine and the hosiery turning device. It is sufficient to simply turn the corresponding knob for each pair of bands, which is graduated and easily accessible. In this way, the smallest distance between the belts and the vertical working plane of the turning bar 3 can be set with micrometer precision.

Das Strumpfwendegerät mit den erläuterten Merkmalen und Vorteilen ist äußerst zuverlässig, sehr anpassungsfähig und einfach im Betrieb, so daß selbst nicht besonders geschultes Personal eingesetzt werden kann.The hosiery turning device with the explained features and advantages is extremely reliable, very adaptable and easy to operate, so that even not particularly trained personnel can be used.

Selbstverständlich können Einzelheiten der Erfindung im Rahmen des Erfindungsgedankens abgeändert werden.Of course, details of the invention can be modified within the scope of the inventive concept.

Wenn das Strumpfwendegerät beispielsweise mit einer Kettelmaschine 41' runder Bauart kombiniert wird (vgl. Figur 11), ist die Backe 27' des Greifers 26' nicht starr am Tragarm 32 des Schlittens 33 befestigt, sondern um eine vertikale Drehachse 60 schwenkbar. Bevor sich der Greifer 26' in Richtung der Wendeorgane bewegt, wird er von einem Pneumatikzylinder 61 aus einer in Figur 11 gestrichelt eingezeichneten Stellung, in der er den Strumpf von den Nadeln 62 des Drehkranzes der Kettelmaschine 41' übernimmt, in eine Stellung gedreht, die im wesentlichen parallel zur vertikalen Arbeitsebene des Wendestabes 3 verläuft und in Figur 11 mit durchgehenden Linien eingezeichnet ist.If the hosiery turning device is combined, for example, with a round construction machine 41 '(see FIG. 11), the jaw 27' of the gripper 26 'is not rigidly attached to the support arm 32 of the slide 33, but rather can be pivoted about a vertical axis of rotation 60. Before the gripper 26 'moves in the direction of the turning elements, it is rotated into a position by a pneumatic cylinder 61 from a position shown in dashed lines in FIG. 11, in which it takes over the stocking from the needles 62 of the rotating ring of the linking machine 41' runs essentially parallel to the vertical working plane of the turning bar 3 and is shown in Figure 11 with solid lines.

Die den Strumpf erfassenden Greifränder der beiden Backen 27' und 28' sind in diesem Fall gekrümmt ausgebildet, wobei die Krümmung an die Kreisbogenform des Drehkranzes der Nadeln 62 angepaßt ist. In gleicher Weise ist auch die Platte 45, welche die Photozelle 43 trägt, gekrümmt (in Figur 11 nicht dargestellt), so daß die Anpassung der Stellung der Photozelle 43 an die Strumpfbreite dadurch erfolgt, daß die Platte 45 mit der Photozelle in Umfangsrichtung des Drehkranzes 62 verstellt wird.In this case, the gripping edges of the two jaws 27 'and 28' which grip the stocking are curved, the curvature being adapted to the circular arc shape of the rotating ring of the needles 62. In the same way, the plate 45, which carries the photocell 43, is curved (not shown in FIG. 11), so that the position of the photocell 43 is adjusted to the stocking width by the plate 45 with the photocell in the circumferential direction of the turntable 62 is adjusted.

Wie bereits erwähnt, kann eine weitere Abänderung darin bestehen, daß die Photozelle 58 weggelassen wird, die im Raum zwischen den Kämmen 46 und den unteren Bändern 8 vorgesehen ist. Dies ist dann vorteilhaft, wenn kleine Strümpfe gewendet werden sollen, und ist dann möglich, wenn die Steuereinheit 59 so programmiert wird, daß die Zykluszeit für einen Wendevorgang fest vorgegeben wird.As already mentioned, a further modification can be that the photocell 58, which is provided in the space between the combs 46 and the lower bands 8, is omitted. This is advantageous if small stockings are to be turned over, and is possible if the control unit 59 is programmed in such a way that the cycle time for a turning process is fixed.

Eine weitere Variante kann darin bestehen, daß der Pneumatikzylinder 6, der für den Antrieb des Wendestabes 3 vorgesehen ist, mit Magnetsensoren 63, 64 und 65 ausgerüstet ist (vgl. Figur 1), welche der Steuereinheit 59 melden, wenn der Wendestab 3 seine oberste, seine unterste und eine mittlere Stellung erreicht hat.Another variant can be that the pneumatic cylinder 6, which is provided for driving the turning bar 3, is equipped with magnetic sensors 63, 64 and 65 (see FIG. 1), which report to the control unit 59 when the turning bar 3 is its uppermost , has reached its lowest and middle position.

In entsprechender Weise kann auch der den Schlitten 33 steuernde Pneumatikzylinder 37 einen mittleren Magnetsensor 66 aufweisen.In a corresponding manner, the pneumatic cylinder 37 controlling the slide 33 can also have a central magnetic sensor 66.

Die jeweils im mittleren Bereich vorgesehenen Magnetsensoren 65 und 66 haben den Vorteil, daß sie über die Steuereinheit 59 bestimmte Funktionen in Gang setzen, bevor der Greifer 26 und/oder der Wendestab 3 die jeweilige Endstellung erreicht hat.The magnetic sensors 65 and 66 provided in the middle area each have the advantage that they initiate certain functions via the control unit 59 before the gripper 26 and / or the turning bar 3 has reached the respective end position.
