Description

The present invention is concerned with delivery devices for the controlled feeding of elongate media, uses of such delivery devices and embroidery machines with such delivery devices. By way of example, the medium can be a thread, wire or ribbon-shaped medium, in particular a soutache medium, such as a soutache thread, which is to be fed to an embroidery machine.

In order to be able to feed such media to an embroidery machine, they are usually wound up wound on spools, which are non-rotatably attached to rotatably mounted spindles. From there, the medium is pulled down. It must be ensured that the medium is supplied with as constant a thread tension as possible. This is especially challenging when the media needs to be fed at variable speed due to the individual embroidery pattern.

One from the EP 1 764 435 A1 Known system includes a passive cord brake, by which the medium is held stretched when piecing. The cord brake may have a number of pins about which the cord can be guided. The braking effect on the cord and thus the cord tension is greater, the more pins the cord is wound. There is the disadvantage that too much delivered material (eg by movement of a soutache wheel or a gate) is not retracted, so that in the short term an uncontrolled situation may arise.

Another known system includes a shaft (so-called soutache wave) with its own drive. Between the shaft and an attached counterpart, the medium is guided / clamped. Through the drive shaft, the delivery or retraction of the Medium are actively controlled. Practically, however, arise in this solution several problems: The clamping between the drive shaft and counterpart is difficult for various media to regulate. For example, while at one point the medium can easily slip through the clamp, there may be a tight clamp elsewhere. Furthermore, the counterpart of the operator must be placed on each embroidery point (of which there can be up to 200 pieces in standard embroidery machines), which is often forgotten in production. Furthermore, during operation, it is possible to temporarily work alternately only in the 2-thread system and then again in the 3-thread system. If the 3-thread system is installed, but only the 2-thread system is working, clamping and vibration of the machine will cause excessive stress on the medium in the clamp and in some cases damage it to such an extent that it can no longer be used.

Other embroidery machines (multi-head embroidery machines) also supply systems are known which regulate the media supply via an individual drive and electronic feedback. However, this is not practical for a Schiffli embroidery machine because it is very costly with up to 200 embroidery sites, with an increased space requirement and u.a. is not flexible.

From the EP 1 462 405 A1 is a hysteresis thread brake for adjusting a uniform yarn tension on Kordierspindeln known. In this case, an existing of a ferromagnetic material hysteresis body, which is driven by a thread to be braked, moved relative to a magnet, which can be achieved an adjustable braking effect. However, since the hysteresis body is driven by the thread, for example, no active retraction of the thread is possible.

The DE 30 08 735 C2 discloses a yarn brake for adjusting the yarn tension for multi-needle embroidery machines. This thread brake has two brake discs, which are pressed against each other by a spring and between which runs the fade to be braked. However, pinching the thread may cause it to be damaged. In addition, with this thread brake no active retraction of the thread is possible.

Also with the in DE 27 58 334 C2 For example, no active retraction of the thread is possible.

In EP 0 634 512 A1 an embroidery machine with a thread brake device is disclosed which has a plurality of yarn brake rollers and a yarn brake shaft coupled thereto, which can be braked or driven centrally. However, the braking effect can not be set separately for each embroidery site.

Overall, there is no satisfactory solution to supply elongated media controlled, especially for the three-thread system (soutache) of Schiffli embroidery machines.

It is an object of the present invention to overcome the disadvantages of the solutions known from the prior art. In particular, a cost-effective, flexible and easy-to-use supply of elongated media for the 3-thread system (soutache) on an embroidery machine, in particular a Schiffli embroidery machine, are provided. The medium should be supplied in a controlled manner and provided with sufficient tension to avoid sticking and / or laying errors as far as possible. The tension should be finely adjustable to deliver both robust and fragile media, such as electrically conductive filaments. The feed should preferably be purely mechanical, ie without individual electronic drive or control. Ideally, an existing drive of the embroidery machine should be used.

These and other objects are achieved in a first aspect of the invention by a feeding device for the controlled feeding of an elongate medium to an embroidery machine. The elongated medium may be, for example thread, wire or ribbon, in particular a soutache medium such as a soutache thread. Such a medium may in some applications also have a plurality of sequins to be embroidered. The embroidery machine can be, for example, a Schiffli embroidery machine. The feeder includes a drive member, a rotatable relative to the drive member spindle for rotatably receiving a coil with the medium wound thereon and torque transmitting means for transmitting a torque between the spindle and the drive member. The medium can be unwound from the spool against this torque.

The drive member, as will be explained in more detail below, can be driven by an external drive which is not part of the feeder. Alternatively, it is also conceivable that the drive member of the feeder itself contains a motor.

Thus, according to the invention torques between the spindle and the drive member can be transmitted. If, for example, the drive member is driven counter to an unwinding direction of the medium, a corresponding torque is transmitted to the spindle and thus to the non-rotatably connected coil by means of the torque transmission means. In this way, the medium can be tensioned against the unwinding, whereby the tension of the medium can be precisely adjusted. Unwinding of the medium takes place when the torque transmittable by the torque transmission means is exceeded. If the force with which the medium is pulled in the direction of the embroidery machine decreases, the torque transmitted by the torque-transmitting means causes the tension of the medium to be maintained.

This results in a controlled supply of the medium with controlled voltage, whereby sticking or laying errors can be reduced or even completely prevented. In addition, can be dispensed with by the inventive feeding device to electronic drives and controls.

Preferably, the torque transmission means are designed as mechanically acting torque transmission means. Such a design is structurally particularly easy to implement. However, it is also conceivable and within the scope of the invention that the torque transmission means act electromechanically or magnetically. For example, the torque between the spindle and the drive member can be transmitted similarly to hysteresis brakes known per se.

Mechanically acting torque-transmitting means may include a first torque-transmitting surface disposed on the drive member and a second torque-transmitting surface disposed on the spindle, which are braced or braced against each other with an axial force. Due to the axial force arise between the torque transmission surfaces frictional forces, which allow a transmission of torque.

Preferably, the axial force is adjustable to adjust the torque transmitted between the spindle and the drive member. In this way, the supply of the medium can be adjusted individually. This is particularly advantageous when several feeding devices according to the invention supply respective media to an embroidery machine, since the axial force can then be adjusted separately for each feeding device, even if all feeding devices are driven by one and the same driving device. However, it is also conceivable and within the scope of the invention that the axial force is fixed.

In some embodiments, it may be useful if the torque transmitting means are adjustable so that in at least one setting of the torque transmitting means, the drive member is rigidly connected to the spindle. Alternatively or additionally, the torque transmission means may also be designed such that in at least one setting of the torque transmission means, the drive member is freely connected to the spindle, so that drive member and spindle are decoupled from each other.

It is advantageous if the drive member has a first limiting element facing the spindle and the spindle has a second limiting element facing the drive element, the first and the second limiting element enclosing a spatial region at least partially, preferably completely, in which the torque transmission surfaces are arranged. In this way, the torque transmission surfaces can be protected from external influences, such as dirt, which could affect the operation.

For example, one of the limiting elements may be formed as a half-shell and the other limiting element also as a half-shell or as a flange. The drive member preferably has a first half shell facing the spindle, and the spindle has a second half shell facing the drive member, the first half shell and the second half shell enclosing the spatial region at least partially, preferably completely, in which the torque transmission surfaces are arranged.

Conveniently, the first torque transmitting surface is resiliently supported on the drive member. Alternatively or additionally, the second torque transmission surface may be resiliently supported on the spindle. By such a resilient support adjustability of the axial force and thus the torque transmitted between the drive member and spindle can be achieved.

With further advantage, the first torque-transmitting surface is formed on a first torque-transmitting body, and this first torque-transmitting body has at least one, preferably at least two, axially on one side opposite the first torque-transmitting surface

Direction extending receiving sleeves in which a spring is at least partially added to the resilient support. The torque transmission body may for example consist of a plastic such as polyamide or of a metal. The receiving sleeve can serve the axial guidance of the spring. If at least two such receiving sleeves are provided with respective spring, vibrations between the drive member and spindle can be suppressed more effectively. Preferably, several springs are arranged uniformly in the circumferential direction for this purpose.

The drive member preferably contains at least one, preferably at least two, receiving openings in which the receiving sleeve (s) and the spring (s) are / are at least partially accommodated. Such receiving openings allow a further improved leadership of the springs.

It is also expedient if the feed device has a holder for attaching the feed device to the embroidery machine, in particular detachably, in particular on a static part of the embroidery machine, wherein the drive element and the spindle are rotatably held on the holder. Such a holder facilitates the mounting of the feeding device on an embroidery machine. If the holder can be detachably fastened, then the feeding device can be removed or repositioned as required.

With further advantage, the drive member and the spindle are arranged on a common bearing shaft, which is firmly connected to the holder or firmly connected. Such training is structurally particularly simple.

With further preference, clamping means, at least a first bearing shaft thread and an adjusting element, in particular an adjusting screw, are arranged on the bearing shaft. The clamping means serve to generate an axial force on the spindle in the direction of the drive member. The bearing shaft thread is engaged with a mating thread of the bracket. The adjustment member also has a thread which engages a bearing shaft thread, which may be the first bearing shaft thread or a separate second bearing shaft thread. The arrangement of the clamping means, the bearing shaft thread and the adjusting element on the bearing shaft is such that the axial position of the bearing shaft relative to the holder and thereby the axial force by turning the adjusting element are adjustable. As has already been explained above, by adjusting the axial force between the drive member and the spindle, in particular between their torque transmission surfaces, the torque transmitted between the spindle and the drive member can be adjusted.

It is also advantageous if a locking element with a thread, in particular a lock nut, is arranged on the bearing shaft, which is in engagement with a bearing shaft thread, in particular a bearing shaft thread as described above. As a result, the axial position of the bearing shaft relative to the holder can be determined. In this way, therefore, the axial force between the drive member and spindle can be determined, and the axial force can only be changed by loosening the locking element again. The explained use of threads is structurally quite simple.

Advantageously, the drive member can be brought into operative connection with a drive device of the embroidery machine in order to drive the drive member. In many cases, it is then possible to resort to a drive device which is present anyway on the embroidery machine, for example to a soutache shaft of the embroidery machine.

For this purpose, the drive member may be disc-shaped and be provided on the outer circumference with an annular frictional engagement element, for example with an O-ring. For example, the drive member can be driven by contact of the frictional engagement element with a soutache shaft. Even if several of the feed devices according to the invention are driven by a common soutache shaft, the axial forces and thus the transmitted torques for each feed device can be adjusted separately by the adjustment elements described above.

A particularly simple releasable connection between the holder and embroidery machine can be achieved in that the holder is designed for snap connection with the embroidery machine.

Furthermore, the supply device may include a protective hood which is designed and arranged to cover a coil accommodated by the spindle. As a result, the wound on the coil medium can be protected from damage.

Another aspect of the invention relates to a use of at least one feeding device as described above for the controlled feeding of an elongate medium to an embroidery machine. As already explained, the elongated medium can be, for example, thread, wire or ribbon. In particular, it may be a soutache medium such as a soutache thread. The embroidery machine can be designed as a Schiffli embroidery machine. Through this use of the feeding device for feeding the medium to the embroidery machine, the advantages already described in detail above can be achieved. For many applications, it is furthermore advantageous if a plurality of feed devices according to the invention are used on one and the same embroidery machine.

For example, a soutache shaft of the embroidery machine may be used as a drive device to drive the drive member of the feeder. If there are several feed devices, the transmitted torque can be set separately for each.

For the reasons mentioned above, it is advantageous if the spindle of the feed device at least temporarily rotates counter to an unwinding direction of a medium. In certain applications, however, it may well be reasonable, and it is within the scope of the invention, when the spindle of the feeder rotates at least partially in the unwinding of the medium.

A third aspect of the invention relates to an embroidery machine, in particular a Schiffli embroidery machine, which contains at least one inventive feeding device as explained above.

The in the FIGS. 1 to 3 The first feeding device 10 according to the present invention includes a holder 11 having a clamp 33 for releasably fixing the feeding device 10 to an embroidering machine and a connecting portion 36, a driving member 12 rotatably supported on the connecting portion 36 of the holder 11, and a spindle 13 rotatably held on the connecting portion 36 of the holder 11 With the aid of the clamp 33, which is held by means of a screw 34 and a washer 35 on the connecting portion 36, the holder 11 and thus the feeder 10 can be mounted on a static part of an embroidery machine as a whole, by a snap connection. The drive member 12 is disc-shaped and provided on the outer circumference with an O-ring 32 which forms an annular frictional engagement element.

As is clear from the Figures 2 and 3 results, the drive member 12 and the spindle 13 are arranged on a common bearing shaft 23. On the bearing shaft 23, a bearing shaft thread 25 is formed, which is in engagement with a mating thread 26 of the connecting portion 36 of the holder 11. This connection is secured by a lock screw 42. In this way, the spindle 13 is rotatable relative to the drive member 12. The spindle 13 is designed for non-rotatably receiving a coil, not shown here, with the medium wound thereon. To hold a spool, the spindle 13 has an O-ring 43.

The drive member 12 has a spindle 13 facing the first half-shell 16. On the spindle 13, a drive member 12 facing flange 37 is formed. The first half shell 16 and the flange 37 partially enclose a space area 18. In order to counteract the penetration of external contaminants even better, the space portion 18, in contrast to the representation in the FIGS. 1 and 2 also be completely enclosed by the first half-shell 16 and the flange 37. In this space area 18, a spring 21 and a washer 38, which enclose an axial portion of the bearing shaft 23 concentrically, and an axial extension 47 formed on the flange 47 of the spindle 13 are arranged. The spring 21 and the washer 38 are supported in the axial direction between the drive member 12 and the extension 47 of the spindle 13. The projection 47 facing side of the washer 38 forms a first torque transmitting surface 14, and the washer 38 facing end face of the extension 47 forms a second torque transmitting surface 15. The torque transmitting surfaces are used for the mechanical transmission of torque between the spindle 13 and the drive member 12. Die erste Torque transmission surface 14 is resiliently supported by the spring 21 on the drive member 12.

At the end remote from the drive member 12, the bearing shaft 23 has an internal thread 39. By a washer 41, a screw 40 is inserted into this internal thread 39. In this way, the spindle 13 is tensioned against the force of the spring 21 in the direction of the drive member 12. This creates an axial force between the two torque transmitting surfaces 14, 15. The screw 40 and the washer 41 thus form clamping means for generating an axial force on the spindle 13 in the direction of the drive member 12. By choosing the thickness of the spring 21 between the extension 47 Washer 38 and / or by the Providing a plurality of such washers 38, the axial force can be adjusted.

In the FIGS. 4 to 6 a second inventive feeding device 110 is shown. This also includes a holder 111 with a clamp 133 and a connecting portion 136, a drive member 112 with an O-ring 132 disposed on the outer circumference and a spindle 113 for rotatably receiving a coil. The clamp 133 is also held at this connecting device 110 by means of a screw 134 on the connecting portion 136. In contrast to the first embodiment, however, the screw 134 is here arranged centrally with respect to the clamp 133 and extends in a longitudinal direction of the connecting portion 136, ie perpendicular to the common axis of rotation of the drive member 112 and the spindle 113th

The drive member 112 has a spindle 113 facing the first half-shell 116, and the spindle 113 has a drive member 112 facing the second half-shell 117. Between the first half-shell 116 and the second half-shell 117, a space region 118 is partially enclosed, in which a first torque-transmitting body 119 is arranged. The torque transmission body 119 may for example consist of a plastic such as polyamide or a metal. In order to counteract the penetration of external contaminants even better, in this embodiment, the space area 118 in contrast to the representation in the FIGS. 4 and 5 be completely enclosed by the half-shells 116 and 117. On its side facing the second half-shell 117, the torque-transmitting body 119 includes a first torque-transmitting surface 114. The second half-shell 117 includes a second torque-transmitting surface 115 on its side facing the drive member 112. A washer 146 is optionally disposed between the torque-transmitting surfaces 114, 115. Is a such washer 146, the torque transmitting surfaces 114, 115 are formed by surfaces of the torque transmitting body 119 and washer 146 and / or surfaces of the washer 146 and the second half shell 117. The two torque transmission surfaces 114, 115 are braced against each other with an axial force, so that a torque between the drive member 112 and the spindle 113 can be transmitted, which will be explained in more detail below.

At its end facing away from the drive member 112, the bearing shaft 132 includes an internal thread 139 into which a screw 140 guided by a washer 141 is inserted. As a result, the said axial force can be generated. Further, a first bearing shaft thread 125 is formed on the bearing shaft 123, which is engaged with a counter-thread 126 formed in the connecting portion 136. Furthermore, an adjusting screw 127 is provided with a thread 128 which is in engagement with a second bearing shaft thread 144. The second bearing shaft thread 144 has a smaller diameter than the first bearing shaft thread 125. By this arrangement, the axial position of the bearing shaft 123 relative to the bracket 111 and thereby said axial force by turning the adjusting screw 127 is adjustable.

On the bearing shaft 123, a locking element formed as a lock nut 129 is further arranged with a thread 130 which is in engagement with the first bearing shaft thread 125. Between lock nut 129 and connecting portion 136, a washer 145 is arranged. As a result, the axial position of the bearing shaft 123 relative to the holder 111 can be determined, whereby the axial force can be determined.

The first torque-transmitting body 119 has, on a side opposite the first torque-transmitting surface 114, two receiving sleeves extending in the axial direction 120, in which in each case a spring 121 is partially received for resilient support. The drive member 112 includes correspondingly two receiving openings 122, in each of which one of the receiving sleeves 120 and one of the springs 121 are partially received. As a result, an improved suspension is achieved.

In FIG. 7 schematically a part of a Schiffli embroidery machine 180 is shown. This includes a per se known rotatable soutache shaft 181 and attached thereto second inventive feeding device 110 according to Figures 4 to 6. This is fixed by means of its holder 111 to a static part 182 of the embroidery machine 180, in such a way that the drive member 112 of the feeder 110 is in contact with and can be driven by the soutache shaft 181. On the spindle 113, a spool 161 with it wound on soutache thread 160 is rotatably mounted.

In operation of the embroidery machine 180, the soutache shaft 181 drives the drive member 112 of the feeder 110. As an alternative to the Soutache shaft 181, the drive member 112 could also be driven by another drive. By means of the torque transmission surfaces 114, 115, a torque is transmitted from the drive member 112 to the spindle 113 and thus to the coil 161. The transmission of the torque to the spindle 113 is at least temporarily counter to an unwinding A of the Soutache thread 160. Contrary to this torque, the soutache thread 160 is unwound from the spool 161. Controlled conveying of the soutache thread 160 is also possible by reversing the direction of rotation, as it were a continuous alternation within an embroidery pattern.

By controlling the embroidery machine 180, the rotational speed of the soutache shaft 181 and thus the rotational speed of the spindle 161 can be precisely adjusted to a desired embroidery pattern. As explained in detail above, can Alternatively or additionally, the torque between the drive member 112 and spindle 113 can be adjusted by adjusting the axial force acting therebetween.

Overall, the soutache thread 160 can be controlled and precisely fed to the embroidery machine 180 due to the construction according to the invention. The feeders 10, 110 are small, handy, and are easy to assemble and disassemble. They can be easily disassembled when not in use, and do not hinder the operation of the embroidery machine 180 in normal operation.
