Description

The invention relates to a magazine device for labels or the like in labeling machines, with a main magazine supplying the labels by means of a feed device to a removal point, an associated receptacle for an aligned, exchangeable change magazine, which has an entry opening on one long side for a filled change magazine and on another side has an outlet opening for an empty interchangeable magazine, a storage conveyor track accommodating a plurality of interchangeable magazines adjoining the inlet opening.

A magazine device of the type just mentioned is known from DE-OS 21 53 169. The interchangeable magazines have a rectangular cross section and are fed to the receptacle transversely to their longitudinal extent in the horizontal direction. When emptying, they are aligned with the main magazine. They are then removed from the device through the outlet opening on the longitudinal side opposite the inlet opening. Measures to fix the change magazine in the holder are not specified. The same applies to the automation of the exchange process.

Furthermore, a magazine device is already known in which the main magazine made up of container rails is considerably shorter than the trough-shaped receptacle or a trough-like change magazine inserted into it (DE-OS 23 03 547). The change magazine takes over the guidance of the labels in the area of the receptacle until they pass through

the feed device formed from two slides has been gradually transferred into the main magazine. The exchange magazine must therefore remain in the holder until it is completely emptied. This known magazine device is barely longer than a conventional label container and is extremely compact, so that multiple arrangements in labeling machines for multiple labeling of bottles are no problem. The known magazine device also enables a noticeable relief for the operator, since he can refill several thousand labels at once with a single operation. In addition, the division of the magazine device into a main magazine which is firmly connected to the labeling machine and which takes over the very important guidance of the labels shortly before the removal, and an exchangeable magazine which takes over the less important guidance of the labels in the rear region of the magazine device enables the use of the most varied of changing magazines to those that serve as packaging or transport containers between the label manufacturer and the label consumer.

It is unfavorable, however, that due to the rigid design of the lateral stops or holders for an interchangeable magazine in the receptacle, a filled interchangeable magazine is inserted into the receptacle essentially from above and / or from behind and an empty interchangeable magazine essentially upwards and / or after must be removed from the back of the holder In particular, threading a full interchangeable magazine can cause certain difficulties for the operator due to its considerable weight, especially where it is not facilitated by any special aids. This type of threading and removing the change magazines also prevents further simplification or automation of an exchange process.

On the other hand, a magazine device for labels with a main magazine firmly connected to a labeling machine and an interchangeable magazine of approximately the same length is already known, in which the recording is formed by a turntable arranged behind the main magazine (DE-OS 21 45 508). The turntable is equipped on its circumference with a large number of interchangeable magazines, which can also serve as transport containers, and after the emptying of the interchangeable magazine aligned with the main magazine, is rotated by an angular step by the feed device designed as a slide, so that a filled interchangeable magazine behind it Main magazine comes to rest. In this way, the operator of the labeling machine can be relieved and the exchange process can be largely automated.

A disadvantage of this known magazine device, however, is the enormous design effort and space required for the turntable and its drive and control, which also complicates a multiple arrangement in the context of multiple labeling of bottles or the like. This device has therefore not found its way into practice. In this context, it is important that a storage device for holding several filled change magazines does not significantly shorten the total time for adding the labels by the operator, since each individual change magazine is still filled with labels or, if used as a transport container, removed from the outer packaging and must be freed of any transport locks before it can be used in the storage device or the turntable. Rather, the time between two filling processes on the storage device, ie the buffer time in which the operator can carry out various other work, is decisively extended. It is obvious that the label processing companies are not willing to use relatively high investment costs for this increase in the buffer time alone.

The invention has for its object to relieve the operator significantly in a magazine device of the type mentioned with simple means and while largely maintaining the compact design and to create the possibility of automating the exchange process for a removable magazine.

This object is achieved by the features specified in the characterizing part of claim 1.

In the case of a magazine device according to the invention, a larger number of filled change magazines can be kept on standby on the storage conveyor track, the filled operator being able to put on filled change magazines at any time. If the exchange of an empty change magazine is required, a filled change magazine is inserted into the entry opening from the side and at the same time the empty change magazine is ejected through the exit opening on the opposite side, preferably through direct contact with the subsequent filled change magazine. The rigid stop acting on the labels or the retractable stop acting on the exchangeable magazine ensures that the new exchangeable magazine assumes its correct lateral position in which it is aligned with the main magazine. On the other hand, the ejection of the empty change magazine is not hindered by the special design of these attacks. The exchange process can therefore be carried out extremely quickly and easily both manually and automatically. The length of the magazine device is not increased by the storage conveyor track and the increase in width also remains within limits with a sufficient capacity of 6 to 10 filled change magazines. In addition, no special transport device is required for the ejected empty interchangeable magazine; the ejection can instead take place directly into a collecting container or the like. The magazine device thus remains free of larger attachments on the side of the outlet opening and is easily accessible here.

In order to reduce the footprint of the magazine device without sacrificing storage capacity and at the same time to simplify the function, it is provided in an advantageous development of the invention that the storage conveyor track is oriented vertically. In this embodiment, it can be provided that the storage conveyor track has an essentially vertically arranged storage shaft, within which the interchangeable containers are stacked one above the other with their longitudinal extent aligned. The required footprint of the storage shaft is hardly larger than that of an exchangeable magazine. Nevertheless, almost any capacity can be achieved by appropriately dimensioning the height of the storage shaft. There is generally sufficient space available upwards on labeling machines; underlying facilities of the labeling machine are not impaired in their accessibility by the memory. In addition, the advance of the change magazines in the storage shaft from the inlet opening to the outlet opening is effected solely by their own weight, so that no special transport devices with a long stroke are required for this purpose. The design effort and thus the investment costs for the storage shaft are very low. In addition, a fully automatic mode of operation can be accomplished with simple means. The memory can be used in magazine devices of various types, regardless of how the changeable magazines are inserted into the receptacle, how they are fixed in the receptacle and how the empty changeable magazines are removed from the receptacle. It also doesn't matter whether the Maga tinning device is operated manually or works more or less automatically. In any case, the vertical storage shaft with the interchangeable magazines stacked on top of one another enables an enormous stock of labels directly inside the magazine device.

In the embodiment of the invention described below, the focus is also on reducing the space requirement, ensuring safe operation and, at the same time, minimizing the control processes when taking in a filled change magazine, emptying it or ejecting the empty change magazine.

This advantageous development is characterized in that the outlet opening for empty interchangeable magazines is arranged on the rear end of the receptacle facing away from the removal point, and in that a feed device acting against the feed direction for the labels is provided for an interchangeable magazine seated in the receptacle.

The invention also includes a method for exchanging the change magazines. With him, an empty change magazine is not ejected in the same direction as the insertion of a full change magazine, but there is an approximately right-angled change in the direction of movement. Space is therefore only required on one long side of the receptacle for feeding the full change magazines; the opposite side remains free. There are no space problems in the rear area of the recording, where the empty change magazines are now being ejected. That area lies generally outside the table top of a conventional labeling machine and is farthest from the labeling point. The empty change magazines can therefore be easily collected at this point. In addition, an optimal lateral fixation of the change magazines is now possible on the free longitudinal side of the receptacle, which has no influence on the course of the ejection movement.

Advantageous developments of the method according to the invention are specified in claims 64 to 71. Particularly noteworthy are the method steps according to claims 68 to 70. These have the effect that the ejection of an empty change magazine does not require any additional time and can be easily coupled with the movement of the label pusher. The method steps in claim 71 are also extremely advantageous. They ensure an optimal fixation of the full change magazine during the removal of the labels at the fixed stop as well as a precisely defined ejection movement of the empty change magazine through the guide channel, as it is formed by the fixed stop on the one hand and the subsequent full change magazine on the other.

The magazine device according to FIGS. 1 to 5 is integrated in a bottle labeling machine, not shown, in which the labels 48 are removed from a stationary stack by glued pallets 47 will. It has a main magazine 16 constructed from a frame 49 and a plurality of container rails 50, which feeds the labels 48 exactly to the removal point. Two bottom-side container rails 50 and lower, lateral container rails 50 are extended away from the removal point with respect to the others, as a result of which an engagement space for the two label slides 32 and 33 is formed. The rear end faces 31 of the elongated container rails 50, which are further away from the removal point, also serve as a stop for an interchangeable magazine 3 and define its front end position in a receptacle 1 that is firmly connected to the main magazine 16. This receptacle 1 is directly connected to the rear end of the Main magazine 16 and has a horizontal base plate 11.

On the left longitudinal side of the receptacle 1, as seen in the feed direction of the labels 48, an inlet opening 2 for filled exchangeable magazines 3 which is unlimited at the top is formed. On the other hand, on this side of the receptacle 1 there are no lateral fixing elements for an exchangeable magazine 3. On the opposite right longitudinal side of the receptacle 1, an outlet opening 7 for empty change magazines 3, which is limited in height by a guide rail 14, is formed. Inlet opening 2 and outlet opening 7 lie diametrically opposite one another and are somewhat longer than an exchangeable magazine 3. For exact lateral determination of the exchangeable magazine 3 in its emptying position aligned with the main magazine 16, two cams 13 are provided in the area of the outlet opening 7, which engage laterally on the exchangeable magazine 3 and are retractable under the bottom of the receptacle 1 by means of an actuator 15. In addition, the emptying position of the interchangeable magazine 3 is limited by the guide rail 14, which extends over the entire length of the receptacle 1 and on the labels 35 stacked in the interchangeable magazine 3

48 attacks. This guide rail 14 is shown in dash-dot lines in FIGS. 3 and 5. The fixation by the guide rail 14 is only effective as long as there are labels in the exchangeable magazine 3. It is not possible with all forms of labels and change magazines. On the other hand, it makes it possible to dispense with movable cams 13 or the like in certain cases.

The change magazines 3 serve as transport containers in the present case and are made of cardboard. They are trough-shaped and provided on one end with a wall which has a cutout 51 for a label pusher 33. The other end face is open and provided with side tabs 52 and a lower tab 46. The tabs 46 and 52 serve to better hold the labels in the interchangeable magazine both during transport and during insertion into the receptacle 1 of the magazine device. When the labels are pushed out by the label pusher 33, the tabs 46 and 52 open automatically, the lower tab 46 laying on the lower container rails 50 and thus ensuring a trouble-free transition of the labels from the exchangeable magazine 3 into the main magazine 16. The stops 31 engage in the front area of the interchangeable magazine 3 that is free of tabs. This interchangeable magazine 3 is already filled with labels by the label manufacturer, with additional protection, e.g. is provided in the form of a shrink film. This shrink film is removed before insertion into the magazine device.

The magazine device has two independent label slides 32 and 33, both of which can be moved in the feed direction. One of them, the so-called main slide 33, covers the entire area from the main magazine 16 to the rear end of an exchangeable magazine 3. It is slidably mounted on a rod 53 arranged above the receptacle 1, which on the one hand on the frame 49 and on the other hand on a bearing block 54 attached is, which in turn sits at the rear end of the receptacle 1. A spring roller 36 is mounted on the bearing block 54, on which a first rope is fastened and wound up. This rope leads via a deflection roller (55) mounted on the frame ₄₉ to the main slide 33 and is fastened there. The spring roller 36 thus causes the normal _E label feed in a conventional manner. A cable drum 35, which is connected to a drive motor 56, is also mounted on the bearing block 54. The rope wound or fastened on this rope drum 35 is also fastened directly to the main slide 33 at the other end. With the cable drum 35 and the drive motor 56, the label pusher (33) can thus be moved against the force of the spring drum 36 in a direction opposite to the feed direction back to its rear end position.

The other label pusher 32, the so-called auxiliary pusher, only covers the rear part of the main magazine 16. Its two wings, which engage the labels next to the main pusher 33, are pivotally mounted on a carriage 57 transversely to the feed direction. The carriage 57 is guided in channel-shaped profiles on the underside of the main magazine 16 by means of four wheels 58 exactly in the feed direction. It is attacked by a double-acting compressed air cylinder 34, through which the auxiliary slide 32 can be driven either in or against the feed direction. Another double-acting pneumatic cylinder 37 is inserted between the counter arms of its two wings, by means of which the auxiliary slide 32 can be brought into or out of engagement with the labels 48 in the main magazine 16.

The outlet opening 7 of the receptacle 1 is followed by a simple collecting device 18 for the ejected empty change magazines 3, consisting of a short, downward slideway with a holding bracket. This collecting device 18 forms, together with the other elements of the magazine device described so far, such as main magazine 16, receptacle 1, main slide 33, auxiliary slide 32, etc., a coherent structural unit. This unit is height adjustable by means of two cross members 60 on two vertical columns 61 of the labeling machine stuck. The columns 61 are in turn part of a label trolley (not shown) which, in order to control the label removal from the removal position in which the pallets 47 remove the foremost label 48 from the main magazine 16, can be moved into a neutral position slightly removed from the orbit of the pallets 47.

At the inlet opening 2 of the receptacle 1 is followed by a slideway 8 which is perpendicular to the direction of advance of the labels 48 and has a horizontal slide plate 19 with two parallel lateral guide plates 42. The slideway 8 can accommodate a plurality of interchangeable magazines 3 lying parallel to the feed direction with mutual contact. The guide plates 42 ensure an exact alignment of the change magazines 3 and also prevent the labels 48 from falling out or being damaged on their end faces. The sliding plate 19 lies in one plane with the sliding surface-like bottom of the receptacle 1, so that the change magazines 3 can pass from the slideway 8 into the receptacle 1 without hindrance. Furthermore, the guide plate 42, which is closer to the removal point, is aligned with the stops 31 of the receptacle 1 for the front end face of an exchangeable magazine 3, so that no disabilities can occur at this point either. At the end facing away from the inlet opening 2, the trough-shaped slideway 8 is completely open in order not to hinder the insertion of the filled - change magazines 3. These can thus be inserted into the slideway 8 from above and / or behind. The latter is particularly important when several magazine devices are arranged one above the other, for example when breast and torso labels are applied to bottles at the same time. In order to make loading easier, the slideways 8 can be formed in the same way as also differently designed storage devices derbahnen be provided on opposite sides of the receptacle 1. In addition, the receptacle 1 can have an additional guide bar 62 for the interchangeable magazines 3 at the rear area, which counteracts tilting and ensures that the interchangeable magazine 3 "hits" the outlet opening 7 when it is ejected.

The slideway 8 also has two sliders 27 which are movable in their longitudinal direction and which are mounted in a rotationally fixed but displaceable manner on a rod 63 arranged laterally to the guide plates 42. The rods 63 in turn are rotatably mounted and are each connected to a rotary piston engine 29. This allows them to be swiveled by approx. 90% and fixed in the two end positions. The slides 27 are designed such that they engage in the one angular position of the rods 63 over the guide plates 42 into the interior of the slideway 8 and rest against the rear of the change magazines 3. In the other end position (indicated by dash-dotted lines in FIG. 2), they are completely withdrawn from the interior of the slideway 8 or lie completely outside the path of movement of the change magazines 3 and the labels 48 contained therein. A rope is attached to each slider 27, which closes a deflecting roller 64 mounted on the end of the rod 63 adjacent to the receptacle 1 and from there runs back to a cable drum 65 where it is fastened. The two cable drums 65 are fastened on a common shaft 66 which is rotatably mounted at the rear, open end of the slideway 8 and is connected to a motor 26. The two slides 27 can thus be synchronized by the motor 26 in the direction of replenishment, i.e. towards the recording 1, are driven. The movement against the direction of replenishment takes place with the aid of spring elements 67.

The slides 27 are designed in such a way that in one end position they protrude slightly into the receptacle 1 or entry opening 2, so that the last of the change magazines 3 stored on the slide track 2 is reliably completely completely until it hits the cams 13 in the receptacle 1 can be introduced.

The above-described slideway 8 is cut off from the receptacle 1 by a narrow parting line and, independently of this, rigidly fastened on a column 68 ==. It therefore does not take part in the short longitudinal movement of the main magazine 16 with the receptacle 1 for controlling the label removal. If the label removal is controlled in a different way, e.g. by engaging in the path of movement of the pallets 47, the parting line can of course be omitted and the slideway 8 can be firmly connected to the receptacle 1.

In the rear end region of the main magazine 16, a sensor 38, for example in the form of a reflective light barrier, is attached to the presence of labels 48. As soon as the sensor 38 no longer registers labels 48, it emits a signal. This indicates that the interchangeable magazine 3 inserted in the receptacle 1 has been completely emptied and the rear end of the stack of labels has reached the rear end of the main magazine 16. The signal can be used, for example, to activate an alarm device. to alert the operator in the case of manual replacement. Further, in the rear region of the holder 1 1 is mounted, a limit switch 39 which provides a signal when the Hau ^p tschieber 33, as shown in Fig. Occupies its rear end position. This end position has a certain distance from the rear end face of an inserted magazine 3, so that the exchange of this magazine 3 is not hindered by the main slide 33. Another limit switch 40 fastened in the rear area of the receptacle 1 responds when an interchangeable magazine 3 assumes its removal position defined by the cams 13. Finally, a control member 41 is attached to the slide 8, which responds to the presence of filled change magazines 3 on the slide 8. The control element 41 is formed, for example, by a light barrier aligned obliquely above the sliding plate 19.

The sensor 38, the two limit switches 39, 40 and the control member 41 are connected to a control device 69 (FIG. 15) which, in the manner described below, automatically carries out the exchange of a change magazine 3 without interrupting the label feed and thus the label removal. This process is initiated by a signal from the sensor 38 after the exchange magazine 3 has been emptied. First, the two wings of the auxiliary slide 32 are then pivoted into the movement path of the labels 48 by the pneumatic cylinder 37 from the neutral position indicated by dash-dotted lines in FIG. 4 the auxiliary slide 32 is moved by the pneumatic cylinder 34 from its rear end position at the end of the main magazine 16 in the feed direction until it hits the back of the stack of labels (see FIG. 1). The auxiliary slide 32 now takes over the label feed, driven by the pneumatic cylinder 34. The main slide 33 is then pulled back into its rear end position (see FIG. 1) with the aid of the motor 56 against the force of the spring roller 36. The execution of this process is confirmed by the limit switch 39. Thereupon, the cams 13 are simultaneously briefly lowered by the actuating members 15, for example pneumatic cylinders, and the slides 27 are set in motion by the motor 26 in the replenishment direction. As a result, the filled interchangeable magazine 3 in front of the inlet opening 2 is pushed through the inlet opening into the receptacle 1, at the same time pushing the empty interchangeable magazine 3 out of the receptacle 1 through the outlet opening 7. There is therefore no separate drive for the empty change magazine. The cams 13 are raised again before the empty change magazine 3 has been completely ejected. This may be raised briefly, but this does not have a disruptive effect, on the contrary, it speeds up the ejection of the empty exchange magazine. It is important that the cams 13 protrude again into the outlet opening 7 before the filled change magazine 3 arrives, since they stop the movement of the filled change magazine 3 in the direction of replenishment and ensure the exact fixation of the change magazine 3 in the receptacle 1 in its removal position. The engine 26 is then switched off. This is preferably designed as a pneumatic motor, so that even a long standstill under pressure is not harmful. The fixation of the newly used change magazine 3 on the side of the Entry opening 2 occurs solely by its own weight or by the blocking action of the other change magazines 3 located on the slide 8, with which it is in contact. The main slide 33 is now brought to the rear of the new stack of labels in the exchangeable magazine 3 by the motor 56 reversing under the action of the spring roller 36. He now takes over the label feed again. Thereupon, the auxiliary slide 32 is moved laterally out of the path of movement of the labels with the aid of the pneumatic cylinders 37 and 34 and then moved back into its starting position. The exchange process is now complete. Intervention by the operator is not necessary here. It should also be mentioned that the labels on the front end of the change magazine 3, which has served as a transport container on the way from the label manufacturer to the label consumer, are secured against falling out by the tabs 46 and 52 during insertion into the receptacle 1. These tabs are only opened when the labels are led out of the changing magazine 3 by the main slide 33 and connected to the auxiliary slide 32 or, after its removal, to the remaining stack of labels in the main magazine 16. The interchangeable magazine 3 cannot participate in this longitudinal movement, since its front end edge bears against the stops 31 on the lateral container rails 50. The folded-down lower flap 46 then lies on the two lower container rails 50 and thus enables the labels to transition from the exchangeable magazine 3 into the main magazine 16 in a trouble-free manner.

The control element 41 can serve to alert the operator to the emptying of the slide 8 with the aid of an alarm device. It can also serve to partially automate the reloading of the slideway 8, by causing the slides 27 from their normal working position, in which they engage a change magazine 3, into the position shown in FIG. 2 after each replacement of a change magazine 3 Neutral position indicated by dash-dotted lines is pivoted out, returned in this position to its rearward end position, pivoted back into its normal working position and then moved again in the feed direction until it strikes an exchangeable magazine 3. The operator therefore only has to fill a sufficient number Place change magazines 3 individually or together on the slide plate 19 at any time, regardless of the position of the slide 27. At the given time, the newly set up change magazines 3 are automatically included in the replenishment of the change magazine 3 when the slide 27 is returned as described above.

The magazine device according to FIGS. 6, 7 and 9 differs from that according to FIGS. 1 to 5 in the design of the slideway 8 'and the exchangeable magazine 4. The slideway 8' here has a frame 70 with a U-shaped cross section, which carries a plurality of lateral and lower slide rails 43. The interchangeable magazines 4 made of sheet metal with a U-shaped cross section are open on both end faces and are provided on the side walls with projections 44 which engage between the side slide rails 43. In addition, protruding tabs 45 are provided on the bottom, which protrude under the lateral slide rails 43. In this way, the labels 48 are optimally guided in the interchangeable magazines 4 on their end faces and secured against falling out. The change magazines 4 do not serve as transport containers, but are only filled by the label consumer, e.g. with a correspondingly long label stick held together by an adhesive strip. The lower tab 45 on the side of the main magazine 16 is bent slightly upwards so that it can rest on the two lower container rails 50 when it is inserted into the receptacle 1. The change magazines 4 are in turn fixed in the longitudinal direction by the stops 31 on the two lateral container rails 50.

The two slides 28 of the magazine device according to FIGS. 6 and 7 are designed like ratchet pawls and are pressed downwards by springs 30 into their working position, in which they engage with their vertical end face pointing in the direction of the axis of thrust at the upper edge of the interchangeable magazine 4. When moving against the direction of replenishment, the slides 28 are automatically raised by their inclined sliding surface against the force of the springs 30, so that they cannot exert any force on the change magazines 4. A special control for the working or neutral position of the slide, as is done in the magazine device according to FIGS. 1 to 5 by means of the motors 29, is thus not mandatory. The two slides 28 are each slidably mounted on two parallel guide rods 71 on the side of the slide 8 '. Their lower ends are fastened to endless toothed belts 72, the rear deflection wheels of which are fastened on a shaft 66 which is driven by the motor 26. The front deflection wheels in the area of the main magazine 16 or the receptacle 1 are freely rotatable. The motor 26 allows the two slides 28 to be driven exactly synchronously both in and against the direction of replenishment.

In the magazine device according to FIGS. 1 to 5, change magazines 5 according to FIG. 10 can also be used for breast labels without major changes. It is only necessary to adapt the cross section of the main magazine 16 and the label slides 32 and 33 to the shape of the labels. The interchangeable magazines 5 consist of cardboard blanks, the ends of which are inserted into one another in the middle of the base area after folding. On the two end faces, tabs 46 are provided for holding the labels during transport and when inserting them into the receptacle 1.

11, the slide plate 20 of the slide 9 is inclined by an angle of approximately 20 and the bottom of the receptacle 1 'by an angle of 45 with respect to the horizontal. It is thereby achieved that the interchangeable magazines 6 with the labels 48 in the form of square film blanks for the filming of bottle necks are moved in the feed direction by the slope drive and are inserted into the receptacle 1 'when the cams 13 are withdrawn from the outlet opening 7. In addition, it is achieved that the labels 48 rotated in the horizontal normal position of an interchangeable magazine 6 by 45 relative to their processing position are automatically tilted into the appropriate processing position when inserted into the receptacle 1 '. The interchangeable magazines 6 are here equipped with side walls of different lengths and capture the labels 48 over part of their height. It is therefore again possible to fix the change magazines 6 or labels 48 in the receptacle 1 'by means of a rigid guide rail 14.

In the magazine device according to FIG. 12, the storage conveyor track 10 a horizontal lifting table 21, which can be moved up and down by a cylinder 73 and held at any height. In this way it is possible to insert a pallet 74 with several layers of filled change magazines 3 into the storage conveyor track 10, which are separated from one another by horizontal intermediate layers 75 made of cardboard. These intermediate layers 75 form a slideway, so to speak, when the change magazines 3 of the top layer in each case are moved in the direction of replenishment or are inserted into the receptacle 1. The replenishment movement is effected, for example, by slides 27, not shown, corresponding to FIGS. 1 and 2. The cylinder 73 is controlled by a limit switch 76 which scans the top layer of interchangeable magazines 3 in such a way that the top intermediate layer 75 lies with the receptacle 1 in a common plane. In addition, in this embodiment, the guide rail 14, which laterally engages the labels 48 in the receptacle 1, is mounted so that it can move laterally and cooperates with a limit switch 17. If there are no labels 48 in the receptacle 1, the guide rail 14 projects somewhat into the receptacle 1 under the influence of its own weight or a spring element (not shown). If a filled interchangeable magazine 3 is inserted into the receptacle 1, the guide rail 14 recedes into the end position indicated by dash-dotted lines, in which the interchangeable magazine 3 is aligned with the main magazine 16. In this position, the limit switch 17 emits a signal. It thus has the same effect as the limit switch 40 in FIG. 1 and can be connected to a control device 69.

In the magazine device according to FIG. 13, the storage conveyor track 11 has two endless belts 23 arranged parallel in the direction of replenishment, which run over deflection rollers 22. The forming belt 23 immediately before recording 1, so that it can be moved to control the label take together with the Hau ^p tmagazin 16 in the longitudinal direction. The deflection rollers 22 can all be freely rotatable. In this case, additional slides 27 or the like are required for the transport of the filled change magazines 3, the belts 23 ensuring a low feed force. However, the belts 23 can also be driven directly by the motor 26, for example by being connected to the rear deflection rollers 22 in a rotationally fixed manner. In this case, the replenishment of the change magazines 3 is accomplished directly by the belts 23 leap. The outer surface of the belt 23 can be made smooth and low-friction. In this case, exact control of the motor 26 is not necessary since the belts 23 can slip under the change magazines 3. However, it is also possible to equip the outside of the belts with drivers 77 indicated by dash-dotted lines in FIG. In this case, exact control of the motor 26 is necessary or a slip clutch is switched on between the motor and the deflection rollers 22.

In the magazine arrangement according to Fig. 14, the S ^p Eicher conveyor track a walking beam conveyor 12 with two fixed, arranged in supply direction parallel support rails 78 and two movable, arranged in supply direction parallel walking beams 25. The support rails 78 lie in one plane with the receptacle 1 and slide the filled change magazines 3 on. The lifting beams equipped with drivers 24 can be raised and lowered by means of two pneumatic cylinders 79 and can be moved back and forth by means of a further pneumatic cylinder 80 in and against the feed direction. If a replenishment of a change magazine 3 is required, the lifting beams 25 are moved from the rest position shown in FIG. 14 exactly by the width of a change magazine 3 in the direction of replenishment, a new change magazine 3 being inserted into the receptacle 1 and at the same time an empty change magazine 3 through the Exit opening 7 is ejected through. Then the walking beams 25 are lowered below the transport plane, pushed back into their rear end position and raised again to their starting position. The control of the walking beam movement takes place, for example, by means of adjustable limit switches and can thus be set to different widths of interchangeable magazines 3, regardless of the distance between the drivers 24. In order to be able to carry out the above-described movement, the walking beams 25 are guided in a longitudinally movable manner on the pneumatic cylinders 79 by means of rollers 81, while between the pneumatic cylinders 80 and the walking beams a link guide 82 which enables the walking beams 25 to move vertically is switched on.

• a) Die Wechselmagazine bestehen z.B. aus Pappe oder Kunststoffolie, sind als Transportbehälter ausgeliefert und werden bereits beim Etikettenhersteller mit Etiketten gefüllt. In diesem Falle ist die Gesamtzeit für das Nachladen von Etiketten sehr kurz, da die Bedienungsperson lediglich die vorgefüllten Wechselmagazine einer Umverpackung, z.B. einem Karton, entnehmen und unmittelbar auf die Speicherförderbahn aufsetzen muß.
• b) Die Wechselmagazine bestehen z. B. aus Blech und" werden erst beim Etikettenverbraucher mit den in normaler Verpackung angelieferten Etiketten gefüllt. In diesem Falle ist keine Anpassung der Etiketten-Transportverpackung erforderlich und diese kann äußerst billig ausgeführt sein.

Basically, two different operating modes are possible with the magazine devices described above:

• a) The interchangeable magazines consist, for example, of cardboard or plastic film, are delivered as transport containers and are already used for labeling manufacturer filled with labels. In this case, the total time for reloading labels is very short, since the operator only has to remove the prefilled change magazines from an outer packaging, for example a cardboard box, and place them directly on the storage conveyor track.
• b) The change magazines exist z. B. from sheet metal and "are only filled at the label consumer with the labels delivered in normal packaging. In this case, no adaptation of the label transport packaging is required and this can be carried out extremely cheaply.

In case a) it is possible that the change magazines have different lengths, depending on the type of label. The operator then has to make sure that the change magazines in the storage conveyor track rest as far as possible with their removal-side end face on the corresponding lateral guide wall 42. The rear guide wall 42 can also be arranged so as to be adjustable transversely to the direction of replenishment, possibly together with the associated slide 27 and its drive and guidance.

In case b), it is expedient that the length of the supplied label bars corresponds to the length of an interchangeable magazine in order to optimally utilize its capacity and to facilitate the filling of the interchangeable magazines. In this case, the labels are preferably held together during transport by an adhesive strip or a shrink film wrapping. A correspondingly designed interchangeable magazine 4 'is shown in FIG. 16. This interchangeable magazine 4' is relatively low, so that an adhesive strip 83 holding the labels 48 together during transport is quickly and easily removed by the operator after inserting a label bar into the interchangeable magazine 4 ' can. To adapt to label bars of different lengths, the interchangeable magazine 4 'can be provided, for example, with an adjustable rear end wall or an interchangeable insert. Another possibility is to attach at least one of the lateral guide rails 43 of the slide 8 'to the frame 70 so that it can be adjusted transversely to the direction of replenishment. The 1 simplest method to compensate for label rods of different lengths, however, is that the operator fills up the remaining space at the rear end of a label rod inserted into a change magazine 4 'by means of loose labels provided for this purpose.

For the sake of clarity, the direction of advance of the labels 48 is indicated by an arrow 59 and the direction of advance of the change magazines 3 to 6 by an arrow 84 in the drawings. The invention is of course not limited to the above-described designs of magazine devices. So z. B. the cams 13 may also be arranged in a fixed manner and instead engage the actuating members 15 on the bottom of the interchangeable magazines 3 in such a way that they are raised somewhat during ejection and can thus slide over the cams 13. A lateral fixation for the exchangeable magazine in the receptacle 1 can also be provided in the area of the inlet opening 2, e.g. in the form of a step-like heel, so that the interchangeable magazines 3 sink to a somewhat lower level when inserted into the receptacle 1. A pawl-like design of the stops is also possible.

Further exemplary embodiments of the invention are described below. Only the special features of the further training are dealt with in detail, otherwise reference is made to the above description. The same reference numerals are used for identical or similar parts.

To the side of the receptacle 1, namely on the side of the inlet opening 2, a vertical storage shaft 85 is arranged, which essentially consists of a rectangular base plate 94 and four parallel angle rails 95 attached to it. The bottom plate 94 lies in a horizontal plane with the base plate 11 of the receptacle 1 and forms, together with this, a slideway for the change magazines during the transverse transport from the storage shaft 85 into the receptacle 1. The distance between the four angle rails 95 is such that this one between they are exactly in the normal horizontal position of use on the one hand, and on the other hand enable the change magazine to sink slightly under the influence of gravity. The length of the four angular rails 95 is dimensioned, for example, such that the storage shaft 85 holds a total of six interchangeable magazines that are directly stacked on top of one another. In addition, the storage shaft 85 is aligned in the longitudinal direction in such a way that the interchangeable magazines located in it are exactly parallel to the direction of advance of the labels in the receptacle 1.

An inlet opening 86 is formed on the upper end face of the storage shaft 85, through which the storage shaft 85 is refilled with horizontal change magazines. An opening 87 is provided in the lower end region of the storage shaft 85 on the long side pointing towards the inlet opening 2 of the receptacle 1, through which the lowermost magazine on the base plate 94 can be moved out of the storage shaft 85 parallel to itself. The opening 87 is essentially formed by the leg of the two corresponding angle rails 95 pointing towards the receptacle 1 in the lower one Area has been removed. In order to facilitate the insertion of an interchangeable magazine into the storage shaft 85 in the vertical direction, the upper free ends of the angle rails 95 are widened somewhat.

On the underside of the base plate 94 of the storage shaft 85, a horizontal pneumatic cylinder 96 is fastened transversely to the feed direction of the labels, the piston rod of which protrudes on the side facing away from the receptacle 1. A block-like or beam-like slide 90 is attached to the piston rod, the flat, horizontal underside of which is slightly higher than the base plate 94 or can slide over it. On the front of the slide 90 pointing towards the receptacle 1, the actual, perpendicular abutting surface 92 is formed, which runs parallel to the direction of replenishment of the labels. A horizontal blocking surface 91 is formed on the upper side of the slide 90, which lies slightly lower than the upper side of the lowest interchangeable magazine in the storage shaft 85. An inclined control surface 92 is also formed between the abutting surface 92 and the blocking surface 91. In addition, the slide 89 is dimensioned such that it can penetrate between the angle rails 95 into the interior of the storage shaft 85.

Normally, the slide 90 in its rest position shown in solid lines in FIG. 17 lies completely outside the storage shaft 85. If an exchange of the exchangeable magazine 3 seated in the receptacle 1 is required, the slide 90 is activated by correspondingly actuating the pneumatic cylinder 96 in the direction of the arrow Recording 1 moved. In doing so, he pushes the bottom change magazine with his abutment surface 92 gradually through the opening 87, the next change taking place magazine is initially supported only on the replacement magazine that has just been moved until the support surface 91 of the slide 90 also dips into the storage shaft 85. The movement of the slide 90 continues until the lowermost changeable magazine has been completely led out of the storage shaft 85 and has been completely inserted into the receptacle 1 via the base plate 24 and base plate 11 acting as a slideway, ie until the labels on the guide rail 14 stop At the same time, the empty interchangeable magazine 3 is ejected through the opening 14. At the end of its lifting movement, the slide 90 assumes the position shown in broken lines in FIG. 17. The following change magazines in the storage shaft 85 are prevented from sinking solely by the blocking surface 91 of the slide 90. The slide 90 is now moved back into its rest position by the pneumatic cylinder 96, the downward movement of the subsequent exchangeable magazine beginning after the blocking surface 91 has emerged from the storage shaft 85, braked by the control surface 92. The replenishment movement of the changing magazines in the storage shaft 85 thus takes place solely through Gravity. In the range of movement of the slide 90, the base plate 94 is provided with a corresponding recess.

The changeable magazine, which is aligned with the main magazine, is fixed by the guide rail 14 since the labels lie there. If the interchangeable magazine 3 is completely emptied, the indirect fixation that is no longer required is automatically eliminated. The empty interchangeable magazine can be ejected from the receptacle 1 unhindered through the guide rail 14.

The magazine device according to FIGS. 18 to 22 is integrated in a bottle labeling machine of a conventional type, not shown, in which the labels 48 are removed from a stationary stack by glued pallets 47. It has a main magazine 16 constructed from a frame 49 and a plurality of container rails 50, which feeds the labels 48 exactly to the removal point. The two bottom-side container rails 50 are extended away from the removal point relative to the others, as a result of which engagement space for the two label slides 33 and 32 is formed. The rear, i.e. End faces of the extended lower container rails 50 pointing away from the removal side also serve as a stop for an interchangeable magazine 3 and define its front end position in a receptacle 1 which is firmly connected to the main magazine 16.

The receptacle 1 directly adjoins the rear end of the main magazine 16 and has a horizontal, plate-like base area. On the left longitudinal side of the receptacle 1, as seen in the feed direction of the labels 48, an inlet opening 2 for filled exchangeable magazines 3 which is unlimited at the top is formed. On the opposite right longitudinal side of the receptacle 1, a lateral stop 14 is provided for the interchangeable magazines 3, which is formed by an upwardly bent leg of the horizontal base surface. Through this over the entire length of an interchangeable magazine 3rd effective stop 14, which acts directly on the side wall of an interchangeable magazine, this is exactly fixed in the lateral direction, such that it is aligned with the main magazine 16. The inlet opening 2 is somewhat longer than the interchangeable magazine 3. This is trough-shaped and has a completely open front end from which the labels ⁴⁸ can emerge in the direction of advance. The other, rear end is partially closed, but with a through opening for the Label slide 33 provided. Each change magazine 3 consists made of sheet metal and is filled with new labels directly on the labeling machine. In order to prevent the interchangeable magazine 3 inserted into the receptacle 1 from slipping away from the stop 14, two permanent magnets 98 are attached to the stop 14 and pull the metallic interchangeable magazines 3 against the stop 14. The interchangeable magazines 3 can also be held on the stop 14 by the following filled interchangeable magazines 3 in the storage device described below. At the rear end of the receptacle 1, which is distant from the removal point, there is an outlet opening 7 for the empty change magazines 3 which is unlimited at the top and which is somewhat wider than a change magazine 3.

The magazine device has two independent label slides 33 and 32, both of which can be moved in the feed direction. One of them, the so-called main slide 33, covers the entire area from the main magazine 16 to the rear end of the receptacle 1 or an interchangeable magazine 3 located therein. It is slidably mounted on a rod 53 arranged on the side of the receptacle 1, which is fastened on the one hand to the frame 49 and on the other hand to a bearing block 54 which in turn is seated at the rear end of the receptacle 1. A first spring roller 36 is mounted in the bearing block 54, on which a first rope 107 is fastened and wound up. This rope 107 leads via a deflection roller 55 mounted on the frame 49 to the main slide 33 and is fastened there. The spring roller 36 thus effects the normal label advance in the direction of the arrow 59 in a conventional manner. A cable drum 35, which is connected to a drive motor 56, is also mounted on the bearing block 54. The second rope 108 wound and fastened on this rope drum 35 is fastened directly to the main slide 33 at the other end. By means of the cable drum 35 and the drive motor 56, the label pusher 33 can thus be moved back to its rearward end position, against the force of the spring drum 36, in a direction opposite to the feed direction, indicated by the arrow 109, in which it completely clears the inlet opening 2. The anti-rotation lock of the main slide 33. is done by a roller mounted on it, which runs on the upper edge of the stop 14.

The other label pusher 32, the so-called auxiliary pusher, only sweeps the rear part of the main magazine 16 in the region of the extended lower container rails 5n. Both of its hook-like wings, which act laterally on the labels 48, next to the main pusher 33, are perpendicular to a slide 105 Swiveling axes of rotation. The slide 105 is movably guided parallel to the feed direction by means of two slide strips 110 on the main magazine 16. It has a backdrop-like opening on its underside, into which a stop bar 104 engages. This is fastened to a flat slide 103 which is movably arranged between the bottom of the main magazine 16 and the slide 105 and to which two swivel levers 106 are also articulated. The two pivot levers 106 are connected in a rotationally fixed manner to the hook-like wings of the auxiliary slide 32 and control their pivoting into the working position in which they engage on the back of the stack of labels located in the main magazine 16 (FIG. 21), or in the neutral position in which they are withdrawn from the path of the labels 48 (Fig. 22). The piston rod of a compressed air cylinder 100 attached to the underside of the receptacle 1 engages the flat slide 103. If this is under pressure, it pulls the slide 105 into the rear end position against a stop, not shown, via the stop bar 104. The wings of the auxiliary slide 32 are held in their neutral position via the swivel lever 106 (FIG. 22). If the compressed air cylinder 100 is vented, the flat slide 103 is pulled in the feed direction by a third rope 101 (arrow 59). The cable 101 runs back over a deflection roller 102 on the underside of the frame 49 to a third spring roller 111 on the underside of the receptacle 1 in the rear end region. At the beginning of the movement in the feed direction of the flat slide 103, the two wings of the auxiliary slide 32 are first pivoted into their working position via the pivot lever 106. Only then does the stop bar 104 hit the front boundary of the link in the slide 105 and attempts to move it in the feed direction (FIG. 21). A separate drive element for the movement of the flaps or wings of the auxiliary slide 32 is therefore not necessary. The sequence of movements is correspondingly reversed when the flat slide _{103 is driven} by the pressure medium cylinder 100 against the feed direction in the direction of the arrow 109. First, the two wings are pivoted into their neutral position and then the slide 105 is moved.

At the outlet opening 7 of the receptacle 1 there is a lower-lying collecting device 18 for the ejected empty change magazines 3 in the form of a container. So that the change magazines 3 do not immediately tip down during the ejection, the receptacle 1 is extended beyond the outlet opening 7 in the form of a guide 99. This is recessed in the bottom area in such a way that an exchangeable magazine 3 tilts sideways downward into the collecting device 99 after the holder 1 has left the holder 1 or shortly before.

The elements of the magazine device described so far, such as main magazine 16, receptacle 1, main slide 33, auxiliary slide 32, etc., form a coherent structural unit. This structural unit is clamped in height-adjustable manner on two vertical columns 61 of the labeling machine by means of two cross members 60. The columns 61 are in turn part of a label trolley, not shown, which, in order to control the label removal from the removal position, in which the glue pallets 47 remove the foremost label 48 from the main magazine 16, can be moved into a neutral position slightly removed from the orbit of the pallets 47.

At the inlet opening 2 of the receptacle 1 there is a memory 112 for several filled change magazines 3. This has a storage conveyor track with a horizontal slideway 8, the parallel guides 42 for the two Has end faces of the change magazines or the labels located therein. The slideway 8 lies in one plane with the horizontal base of the receptacle 1 and merges smoothly into it. The filled change magazines 3 can therefore be transferred from the memory 112 into the receptacle 1 without hindrance in the direction of the arrow 84. The insertion movement is inevitably ended by the impact of an interchangeable magazine 3 on the stop 14. On the front side facing away from the inlet opening 2 and upwards, the store 112 is completely open in order to enable the filled change magazines 3 to be inserted easily.

The memory 112 also has two slides 27 for the interchangeable magazines 3 in the form of resilient pawls, which are mounted on both sides of the slide 8 on two parallel, horizontal rods 6 _{3 so as to be} displaceable and rotationally fixed. The slides 27 are pressed into their working position by springs, in which they protrude into the movement path of the change magazines 3 on the slideway 8 and can engage on the side surface of the last change magazine. When moving against the direction of replenishment, the slides 27 are automatically pushed out of the path of movement of the change magazines 3 if there are further filled change magazines 3 behind them. A special movement control for the slide 27 is therefore not necessary. The two sliders 27 are driven in the direction of replenishment (arrow 84) and in the opposite direction by a motor 26. This drives two toothed belts 113, which run underneath the respective rod 63 and are fastened to the slides 27 and their bearing blocks. The motor 26 is designed as a brake motor so that an automatic retraction of the change magazines 3 on the slide 8 against the direction of replenishment cannot occur. The two toothed belts 113 are endless and each run around a loose deflection roller, arranged in the area of the inlet opening 2, and via a drive roller driven by the motor 26, arranged in the rear end area of the slideway 8.

The slideway 8 of the memory 112 is separated from the receptacle 1 or its horizontal base surface by a narrow parting line and fastened on its own holding column 68. It therefore does not take part in the short longitudinal movement of the main magazine 16 with the receptacle 1 for controlling the label removal. Control of label removal takes place on. another way, for example by an intervention in the path of movement of the glue pallets 47, the parting line can of course be omitted and the slideway 8 can merge seamlessly into the receptacle ₁ .

On the rear side of the plate-shaped main slide 33 facing away from the labels 48, a lever-like, essentially vertically directed driver 97 is pivotally mounted at its upper end about a horizontal axis. The driver 97 hangs down under the influence of its own weight. If the main slide 33 is located inside an exchangeable magazine 3 (FIG. 18), the driver 97, with its bevelled lower end face, grinds against the bottom of the exchangeable magazine 3, whereby it is slightly raised. If the main slide 33 completely emerges from the interchangeable magazine 3, the driver 97 falls completely downwards, since the interchangeable magazine 3 is guided slightly higher in the receptacle 1 by two rails 114 (FIGS. 19 and 20). If the main slide 33 now moves in the direction of the arrow 109 against the feed direction, the driver 97 engages directly on the front end edge of the interchangeable magazine 3 and pushes it completely out of the receptacle 1 through the outlet opening 7 against the feed direction. The ejected interchangeable magazine 3 initially moves exclusively in its longitudinal direction until, due to the special design of the guide 99, it tilts to the side and downwards. If the main slide 33 with the driver 97 is then moved again in the feed direction (arrow 59), it passes through the rear end face of the new, provided with a corresponding recess. filled change magazine 3, the driver 97 is automatically raised accordingly by the lower limit of this recess so that it slips over it.

The motor 56, the pressure medium cylinder 100 and the motor 26 are controlled automatically by a control device (not shown) in the sense of a continuous replenishment of the labels 48. A total of four non-contact limit switches 115 to 118 are connected to this control device. The first limit switch 115 gives a signal when the main slide 33 has completely moved out of the change magazine 3 in the receptacle 1 and this change magazine is thus completely empty. The second limit switch 116 indicates that the main slide 33 has reached its rear end position in which it completely clears the entry opening 2. The third limit switch 117 emits a signal when a change magazine 3 is exactly seated in the receptacle 1 in the removal position aligned with the main magazine 16. Finally, the fourth limit switch 118 responds when the two slides 27 move their front, i.e. have reached the end position lying near the inlet opening 2 and the store 112 is thus completely empty.

Due to the special design of the control device, the following procedure results for exchanging an interchangeable magazine 3: In the normal operating state, the interchangeable magazine 3 seated in the receptacle 1, which is supported by the stop rail 14 in cooperation with the magnets 98 and / or its own weight and / or the blocking effect is fixed by the _' next full replacement magazine 3 on the slide 8 and / or the braking action of the slide 27 in connection with the brake motor 26, gradually emptied by the main slide 33 in accordance with the removal of the labels by the glue pallets 47 (FIG. 18). Here, the slightly raised driver 97 on the back of the slide 33 ineffectively slides over the bottom surface of the exchangeable magazine 3. Only when the If the main slide 33 has completely emerged from the exchangeable magazine 3 and is therefore empty, the driver 97 falls down a little and engages on the front end edge of the exchangeable magazine 3 (FIG. 20). Triggered by the limit switch 115, the compressed air cylinder 100, which is normally under pressure, is now vented. As a result, the third spring roller 111 takes effect and pulls the flat slide 103 in the direction of arrow 59 via the cable 101. As a result, the two wings of the auxiliary slide 32 are first pivoted into their working position (FIG. 21) and then the auxiliary slide 32 is moved in the feed direction until it bears against the rear of the stack of labels located in the main magazine 16 (FIG. 19). The auxiliary slide 32 now takes over the normal label feed. Thereupon, the motor 56 is actuated and pulls the main slide 33 against the feed direction in the direction of arrow 109 back into its rear end position up to the stop on the bearing block 54 via the cable 108. The empty change magazine 3 is thereby moved along by the driver 97 acting on its front end face Stop bar 14 pushed through the outlet opening 7 (Fig. 19). This extension movement takes place transversely to the holding force of the permanent magnets 98 and is hardly affected by them. Rather, the permanent magnets 98 ensure that the empty interchangeable magazine 3 "hits" the outlet opening 7 exactly, or does not collide against one of the lateral boundaries 42 of the memory. At the end of the extension movement by the slide 33, the empty interchangeable magazine 3 tilts sideways and downward from the guide 99 and falls into the collecting container _18. Now, triggered by the limit switch 116, the motor 26 is actuated and moves the two slides 27 in Direction of arrow 84. The foremost full interchangeable magazine 3 is completely pushed into the receptacle 1 away from the slideway 8 until it hits the stop rail 14. This insertion movement thus takes place transversely to the feed movement (arrow 59), while the ejection movement for the empty change magazine is exactly opposite to the feed direction he follows. As soon as the full change magazine 3 has reached its removal position in the receptacle 1, this is reported by the limit switch 117. Now the motor 26 is switched off; its braking effect contributes to the fixation of the change magazine 3 in the receptacle. Furthermore, by switching off the motor 56, the main slide 33 is moved in the feed direction by the first spring roller 36 until it rests on the back of the new label stack and now takes over the normal label feed again. Finally, the air cylinder 100 is pressurized. Thereby, over the flat slide 103 · and the lever 106die two flaps of the auxiliary slider 32außer engagement with the labels placed and thereafter the stop bar 10 ₄ and ₁₀₅ moves the carriage back to its rearward stand-by position.

If the memory 112 is completely empty, this is reported by the limit switch 118. This gives a signal to the operator. At the same time, by switching the motor 26, the two slides 27 can be moved into their rearward end position, which is distant from the inlet opening 2, in order to make it easier for the operator to insert the new, filled change magazines 3.

The magazine device is no higher than a normal label container. It is therefore easily possible to arrange several corresponding magazine devices closely one above the other, as is necessary in the case of multiple equipping of bottles, for example with body labels and breast labels. It is expedient to arrange one storage device on the left side and the other storage device on the right side of the respective receptacle. In this case, both stores are very easily accessible from above, while the empty change magazines of both magazine devices can be ejected undisturbed to the rear.
