Description

The invention relates to a strapping device with a packing table which has a surface for positioning a package to be strapped with a frame which surrounds the packing table and which is used to guide a strapping band around the packing table and around the package arranged on it with a positioning device for edge protection means which is used for this purpose is designed to arrange the edge protection means on the package, with a magazine which is designed to receive a plurality of edge protection means and with a conveyor element for edge protection means, which is movable relative to the magazine from a rest position to a discharge position, to an edge protection means from the magazine to the positioning device for edge protection products to be conveyed out.

Such strapping devices are well known from the prior art. With their help, several individual goods are combined into a larger container, so that transport is made easier. It is common to stack several wooden panels on a load carrier, for example a pallet, and then to strap them with a plastic or metal strap so that the wooden panels are securely held together.

The procedure is similar if, for example, several goods packed in individual packaging are put together on a pallet to form a container.

In addition to strapping individual goods in order to put them together to form a transport container, outer packaging is also strapped in order to reliably protect it against accidental opening.

Such cardboard boxes to be closed separately or individual goods to be combined into a bundle are referred to in their entirety as a package within the meaning of the invention. As a package from the EP 2778075 A is a generic Strapping device of the applicant became known. This includes a packing table with several rotatably mounted rollers. At least two vertical supports are arranged to the side of the package, on which a pressure plate aligned parallel to the packing table can be moved vertically. A strapping frame is formed along the pressing plate, the vertical supports and the package, into which the strapping is inserted and guided around the package.

Now the package to be strapped, for example a pallet on which several cardboard boxes are stacked, is placed on the rollers of the packing table and moved in the direction of the strapping frame or press plate. When the package has reached its strapping position, the strap is shot into the strapping frame and stretched around the package.

The aforementioned EP 2778075 A further discloses that the package edges can be protected against damage by means of an edge protection means to be arranged before the strapping process. For this purpose, there is at least one magazine on the press plate in which edge protection means can be kept. A rigid link chain serves as a conveyor unit for a conveyor organ. The conveying organ takes on edge protection means in order to convey them out. From a rest position of the rigid back chain below the magazine, it is moved in the direction of a discharge position. Here it conveys an edge protection agent and transfers it to a positioning device. This is arranged on the press plate and brings the edge protection agent to the edge of the package.

In a particularly advantageous manner, a compactly constructed conveying unit can be created by means of the rigid-backed chain. For this purpose, the rigid-back chain is deflected in the area of the magazine from an essentially horizontal discharge arrangement into a vertical orientation. In this way, the horizontal installation space otherwise required for the forward and backward movement becomes free.

This basically advantageous construction is seen as in need of improvement, because with the back-stiff chain comparatively large masses have to be moved. This results in the need for relatively solidly built, these Mass holding magazine racks. Furthermore, comparatively high demands are made on the drive motors for such rigid back chains, since the masses to be moved trigger high load peaks when starting and ending the discharge or retraction movement. In addition, analyzes have shown that load peaks also occur in the area of the drive when the individual chain links are deflected. Such load peaks reduce the service life of the drive motors used.

The object of the invention is therefore to equip a generic strapping device with a compactly constructed conveyor unit for edge protection means.

The object is achieved by a strapping device with the features of claim 1, in particular with its characterizing features, according to which the conveyor member for edge protection means is attached to a rail, in particular a telescopic rail, which is designed to be extended relative to the magazine in order to the conveyor member for edge protection means to move from the rest position to the discharge position and to enable the conveyor element for edge protection means to convey an edge protection means to the positioning device for edge protection means and the rail, in particular the telescopic rail, is designed to be moved back relative to the magazine in order to move the conveyor element for edge protection means from the discharge position to move to the rest position.

If the conveyor element for edge protection means is attached to a telescopic rail, the installation space available in the horizontal direction can initially continue to be kept small. It is also compared with EP 2778075 A the vertical installation space required for the retraction and extension of the rigid back chain is free.

Telescopic rails can be constructed more easily with the same stability, so that the masses to be moved are lower. As a result, the magazine racks can be constructed statically more simply. This enables a cost reduction in magazine production to be achieved.

If the masses to be moved are reduced, the outfeed and retraction movement of the conveyor unit for edge protection means can be the same Accelerate drive power. Alternatively, the drive power can be reduced with the same movement speed. A correspondingly smaller drive is more cost-effective.

It is provided that the length of the rail corresponds approximately to the length of the magazine, measured in the direction of movement when the rail is extended and retracted. In a particularly preferred embodiment it is provided that the strapping device has a second rail, in particular a second telescopic rail, which is connected to the rail and is set up to extend and retract the conveyor unit for edge protection means.

Another major advantage of using telescopic rails is that they are nested in one another when they are retracted and therefore only take up a small amount of space in the direction of movement. In this way, even when only the space below the magazine is used, a greater distance between the rest position and the discharge position can be bridged by using one or more interconnected telescopic rails, without increasing the horizontal installation space measured in the direction of movement of the conveyor element.

It is provided that the strapping device comprises a drive which is connected to the rail and is designed to extend and retract the rail, in particular when the rail is moved by a belt, in particular a drive belt of a belt drive.

By using a belt drive to move the telescopic rails or the conveyor element, it is possible to provide a reliable and precisely controllable drive in a simple manner.

It is conceivable that the rail and the second rail are extended and retracted simultaneously.

Alternatively, it is conceivable that the rail and the second rail are extended and retracted sequentially.

Furthermore, it is provided that the magazine is designed to hold the edge protection means stacked on top of one another.

In such an embodiment, it is then advantageously possible for the conveying element for edge protection means to be arranged below the magazine in the direction of gravity.

It is also provided that the conveyor member for edge protection means comprises a receiving surface for edge protection means and a separating web which is arranged in the outfeed direction at the rear end of the receiving surface of the conveyor member for edge protection means in order to remove an edge protection means from the magazine.

The height of the separating web roughly corresponds to the thickness of an edge protection means and ensures that only one edge protection means is removed from the magazine during the conveying movement. The rear side of the separating web facing away from the receptacle can be designed in a wedge shape. This ensures that when the conveyor organ moves back, the separating web passes under the lowest edge protection means in the magazine.

Particularly preferred is an embodiment in which a pair of rails, in particular a telescopic rail pair, is used instead of a single rail and a second pair of rails, in particular a telescopic rail pair, is used instead of the second rail, the rails of the respective rail pair being moved simultaneously in the same direction.

By using a pair of telescopic rails instead of a single telescopic rail, the stability and load-bearing capacity can be increased significantly.

It is also provided that the belt is guided circumferentially around a first wheel and a second wheel, the drive being connected to the first wheel or the second wheel, in particular when the second rail is moved by a second belt, in particular a drive belt, provided is that the second belt is indirectly connected to the drive.

The coupling between the drive, the first drive belt and the second drive belt, as shown above, makes it possible to extend or retract two or more telescopic rails with just one motor.

Specifically, it is provided for this that the second belt is guided circumferentially around a third wheel and a fourth wheel, the second belt being coupled to a stationary component of the strapping device, in particular to an immovable component of the magazine, and the third wheel and the fourth wheel being coupled to it the rail are arranged so that the third and fourth wheels are moved with the rail.

Provision is also made for a control which is designed to move the drive for moving the conveyor element for edge protection means from the rest position to the discharge position in order to enable edge protection means to be conveyed out by the conveyor element for edge protection means to the positioning device for edge protection means. It is particularly advantageous if the control is designed to move the positioning device for edge protection means from an initial position to the discharge position in order to receive an edge protection means.

It is also provided that the control is designed to move the conveyor element for edge protection means into the rest position after the edge protection means has been conveyed to the positioning device for edge protection means.

It is conceivable that the control is designed to move the positioning unit for edge protection means into a positioning position in order to position the edge protection means on the edge of a package, in particular if the control is set up to move the positioning device for edge protection means back into its starting position after the edge protection means is positioned on the edge of the package.
Finally, it is provided that the control is designed to control the drive for extending and retracting the rail.

• Moving the conveyor element for edge protection means into the rest position.

The method also provides for the edge protection means to be delivered to the conveyor element for edge protection means in the rest position of the conveyor organ for edge protectors.

Furthermore, the method can also include that the edge protection means is delivered to the conveyor element for edge protection means by the action of gravity.

In the figures, a strapping device according to the invention is provided overall with the reference number 10.

Figure 1 shows the strapping device 10 in its entirety. It comprises a packing table 11, on the sides of which there are two vertical supports 12. A pressing plate 13 is arranged on the vertical supports 12 so that it can be moved vertically.

To the side of the packing table 11 there is also a protective housing 14 in which a so-called bayonet is seated. This can be inserted above the packing table 11 between the runners of a load carrier, for example a pallet. A tape unwinding unit 15, from which a strapping tape is pulled off, is arranged on the protective housing 14.

The packing table 11 has a large number of rollers 16 which are rotatably mounted and on which a package 17 can be guided through the strapping device 10.

An in Figure 1 The strapping channel (not shown) extends along the vertical supports and the pressure plate as well as in the packing table 11. As an alternative to the frame section which is arranged in the packing table 11, the bayonet already mentioned, not shown in detail, can be inserted. In order to strap the package 17, the strap is pulled off the tape unwinding unit 15 and guided around the package 17 along the strapping frame.

How out Figure 1 As can be seen, the press plate 13 carries two magazines 18. These hold edge protection means 19 in front of them. These are conveyed out of the magazines 18 and fed to a positioning unit arranged below the press plate 13. The positioning unit moves the edge protection means 19 to the package edge in order to arrange it there between the package 17 and the strapping material and thus protect the package 17 from damage by the strapping material.

In the Figures 2 to 5 the magazine 18 with its magazine frame 24 is shown in various external views and will now be described in detail below.

Figure 2 shows the magazine provided overall with the reference number 18 in a view of the front facing the press plate. Here the magazine 18 initially has Via a mounting plate 20 which is provided with a large number of bores 21 and which is used to fix the magazine 18 on the press plate.

In addition, the mounting plate 20 has a passage opening 22. This is designed such that a delivery unit can pass through in order to move an edge protection means 19 to a positioning device below the press plate.

Overall, the magazine has four receiving supports 23 with a right-angled cross-section, of which in Figure 2 the receiving supports 23 near the press plate are shown. As will be described in more detail below, these receiving supports 23 form a receiving space 27 for edge protection means 19. The passage opening 22 also allows a view into the magazine frame, which is provided overall with the reference number 24, within which a telescopic rail arrangement 25, to be described in detail later, is located.

The receiving supports 23 are provided with outwardly projecting guide lips 26 at their upper, exposed ends. These serve for the simplified insertion of edge protection means 19, in particular edge protection means 19 resting on top of one another in stacks.

Figure 3 shows the magazine 19 with its magazine rack 24 in side view. In addition to the front receiving supports 23, the rear receiving supports 23, that is to say the receiving supports 23 facing away from the press plate, are also shown here. How to Figure 2 described, the pressing plates facing away from the receiving supports 23 also have guide lips 26, which serve to simplify the insertion of edge protection means 19, in particular edge protection means 19 placed on top of one another in a stack. From the side view it is also clear that a storage space 27 for edge protection means 19 is formed between the receiving supports 23.

The mounting plate 20 close to the press plate can also be seen, as well as frame walls 28 extending from the mounting plate 20 to the rear, that is to say remote from the press plate, which are provided with a rear wall 29 at their ends remote from the press plate. The frame walls 28 form in their end region remote from the press plate one behind the Drive space 30 located at the rear receiving supports 23, in which a drive (not shown in more detail but described in more detail below) for conveying edge protection means 19 can be arranged.

Figure 4 shows a view from above of the magazine 19. In addition to the Figure 2 and 3 Components already described in detail, the conveyor member 31 is shown here in the form of a receiving plate 32 for edge protection means 19 in its rest position. This is located in the area of the storage space 27 for edge protection means.

The representation in Figure 5 corresponds essentially to the illustration according to Figure 4 . However, in Figure 5 the illustration of the conveyor member 31 is omitted, so that now a view of the already in Figure 2 mentioned telescopic rail assembly 25 is possible. The structure of the telescopic rail assembly 25 is now first based on Figure 13 , a sectional view according to section line BB in Figure 10 explained. The position corresponds to the section line BB in Figure 10 the location of the ZZ line in Figure 5 . The sectional view in Figure 13 however, does not show various parts of the magazine rack 24 of the magazine 19.

Figure 13 shows first an outer pair of telescopic rails 40, which is formed by the first telescopic rails 40A and 40B. Each first telescopic rail consists of an outer guide rail 41A / 41B, in each of which an inner guide rail 42A / 42B is arranged so that it can move longitudinally. In an intermediate space 43 between the outer guide rails 41A / 41B and the inner guide rails 42A / 42B, bearing means, for example balls, are arranged, which are not shown here. These serve to minimize friction when the inner guide rail 42A / 42B is pulled out of the outer guide rail 41A / 41B.

The outer pair of telescopic rails 40 is fastened to a respective holding plate 34A / 34B via its outer guide rails 41A / 41B and is mounted in a stationary manner with regard to the magazine frame 24. In the exemplary embodiment, screw connections 44 are used for this. The inner guide rails 42A / 42B, on the other hand, are connected to one another via a mounting plate 45 which is attached to mounting brackets ₄ 6A / ₄ 6B. Due to this connection move the telescopic rails 40A and 40B, more precisely their inner guide rails 42A / 42B at a Extension movement or retraction movement basically simultaneously and in the same direction.

The telescopic rail arrangement 25 furthermore comprises an inner telescopic rail pair 50. This comprises second telescopic rails 50A and 50B, which in turn each comprise an outer guide rail 51A and 51B and an inner guide rail 52A and 52B. Here, too, the inner guide rails 52A / 52B are guided in the outer guide rails 51A / 51B. In an in Figure 13 In the visible intermediate space 53, there are again bearing means, in particular balls, in order to minimize the friction when the inner guide rails 52A / 52B are pulled out of the outer guide rails 51A / 51B. These friction-minimizing bearing means are not shown.

The outer guide rails 51A and 51B are attached to the mounting brackets 46A and 46B of the outer telescopic rails 40A and 40B. They thus move simultaneously and in the same direction with the inner guide rails 42A and 42B of the outer telescopic rails 40A and 40B. Since the inner guide rails 52A and 52B of the second pair of telescopic rails 50 are mounted in the corresponding outer guide rails 41A and 41B, the inner guide rails 52A and 52B also follow the movement of the inner guide rails 42A and 42B of the outer pair of telescopic rails 40.

The inner guide rails 52A and 52B are connected to one another via a mounting bridge 54, so that an extension or retraction movement of the inner guide rails 52A and 52B takes place simultaneously and in the same direction.

Figure 13 also shows a mounting base 33 which does not belong to the telescopic rail arrangement 25 in the narrower sense. This fastening base 33 is also arranged in a stationary manner on the magazine frame 24. It is used to fasten a drive, in particular a motor, a servomotor being the preferred type of drive. In addition, the fastening base 33 carries a first belt wheel 60. This is in operative connection with the servomotor and is driven in rotation by the latter. A first drive belt 61 is placed around the first belt wheel 60 and becomes a second belt wheel (not visible here) 62 led. A first belt clamp 63, formed by a first clamping jaw 64 and a second clamping jaw 65, engages around the first drive belt 61 and is captively attached to it. As a result, the first belt clamp 63 follows every movement of the first drive belt 61.

The first belt clamp 63 is connected to the mounting plate 45 and thus to the first telescopic rails 40A and 40B of the outer pair of telescopic rails 40 via the mounting brackets 46A and 46B. More precisely, there is the coupling to the inner guide rails 42A and 42B of the first telescopic rail pair 40.

There is also a connection to the outer guide rails 51A and 51B of the second telescopic rail pair 50 via the mounting plate 45 and the mounting brackets 46A and 46B.

If the aforementioned servomotor now drives the first belt wheel 60 in rotation, the first drive belt 61 is set in motion. Due to the coupling via the mounting plate 45 and mounting brackets 46A and 46B, its movement is followed by the inner guide rails 42A and 42B of the outer telescopic rail pair 40 and the outer guide rails 51A and 51B of the inner telescopic rail pair 50. In this way, the guide rails 42A and 42B and 51A and 51B can be extended or retracted.

The mounting plate 45 carries a third belt wheel 70 which is rotatably mounted on a wheel axle 76. A second drive belt 71, which is guided to a fourth belt wheel 72, not shown here, is placed around the third belt wheel.

A second belt clamp 73, consisting of a third clamping jaw 74 and a fourth clamping jaw 75, is fixed to the second drive belt 71 and therefore implements its movement.

The second strap clamp 73 is attached to the mounting bracket 54. The mounting bridge 54 itself is attached to the inner guide rails 52A and 52B of the inner telescopic rail pair 50. As a result, the inner guide rails 52A and 52B follow each movement of the second drive belt 71 and can thus be extended or retracted. In addition, the assembly bridge 54 serves to fasten the conveyor element 31, which is designed as a receiving plate 32.

Figure 6 shows a longitudinal section through the magazine 19 along the section line AA in Figure 4 . An enlarged view of the segment X shows Figure 7 . A plan view of the telescopic rail arrangement 25 arranged in the magazine rack 24 is shown Figure 10 . The further structure of the telescopic rail assembly 25 is now based on Figures 7 and 10 shown. For a better classification, it should be pointed out once again that the representation of the Figure 13 a sectional view according to section line BB in Figure 10 and the position of the section line BB in the plane ZZ in Figure 7 can be found.

As from the Figures 7 and 10 As can be seen, the first drive belt 61 is guided circumferentially around the first belt wheel 60 and the second belt wheel 62. A drive of the first belt wheel 60 thus leads to an endlessly revolving movement of the first drive belt 61. The second belt wheel 62, just like the first belt wheel 60, is fixed in a stationary manner on the magazine frame 24. As Figure 7 shows, it is attached to a floor panel 80 of the magazine rack 24 by means of a wheel axle 66.

However, the first belt clamp 63, which is coupled to the mounting plate 45, prevents a completely circumferential movement of the first drive belt 61. As a result, a drive of the first belt pulley 60 leads to an extension movement of the inner guide rails 42A and 42B of the outer telescopic rail pair 40 (in the Figures 7 and 10 not designated) when the first pulley 60 based on the representation of the Figure 10 is moved counterclockwise. Due to the coupling of the mounting plate 45 with the outer guide rails 51A and 51B, which is also present, the inner telescopic rail pair 50 is also moved in the extension direction.

The second drive belt 71 is guided circumferentially around the third belt wheel 70 and the fourth belt wheel 72.

The fourth belt wheel 72 is fastened on a belt wheel carrier 77. The belt pulley carrier 77 is held by the inner guide rails 42A and 42B of the outer telescopic rail pair 40 and is fixedly attached to them.

Thus, both the third belt pulley 70 and the fourth belt pulley 72 are connected to the inner guide rails 42A and 42B in a movement-coupled manner and are also moved in the extension direction S when the outer telescopic rail pair 40 is pushed out.

A third belt clamp 78 is decisive for the extension movement of the inner guide rails 52A and 52B of the inner telescopic rail pair 50. This third belt clamp 78 is identical in structure to the first or second belt clamp 63/73 and is firmly connected to the second drive belt 71. The third belt clamp 78 is fixedly attached to the magazine frame 24. The third belt clamp 78 therefore does not follow the return movement R in the opposite direction during an extension movement S or during an extension movement S. This can be seen in the ones showing the pull-out movement Figures 10 to 12 in that the distance L between the end of the holding plate 34a near the press plate and the third belt clamp 78 has a constant length L.

The telescopic rail arrangement 25 shown in the figures and just explained in detail in terms of structure and function is used to extend the conveyor element 31 from a rest position and to move it in a discharge position (push-out direction S) and then to move it back from the discharge position to the rest position (return movement R). This movement of the telescopic rail assembly 25 is now based on the Figures 10 to 12 explained. It shows Figure 10 the telescopic rail arrangement 25 in the rest position of the conveyor organ, Figure 11 shows the beginning movement in the extension direction S to reach the discharge position, Figure 12 shows the telescopic rail arrangement 25 in the delivery position of the conveyor member 31.

In order to induce a movement of the telescopic rail arrangement 25 in the extension direction S, the drive (not shown) moves the first belt wheel 60 counterclockwise. The first drive belt 61, which is guided in the first belt wheel 60 and second belt wheel 62, also moves counterclockwise. In doing so, it forces the first belt clamp 63 to move in the extension direction S. The inner guide rails 42A and 42B of the outer telescopic rail pair 40 coupled to the first belt clamp 63, as well as the outer guide rails 51A and 51B of the inner, second telescopic rail pair 50, are also conveyed in the direction of extension S.

The inner guide rails 42A and 42B carry the third belt wheel 70 on the mounting plate 45 remote from the press plate and the fourth belt wheel 72 on the belt wheel carrier 77 close to the press plate. The third belt wheel 70 and fourth belt wheel 72 are together with the inner guide rails 42A and 42B of the first telescopic rail pair 40 in Extension direction S moves. This leads to a displacement of the second drive belt 7, which is guided circumferentially around the third belt wheel 70 and the fourth belt wheel 72, based on its in FIG Figure 10 shown original position. Since the second drive belt 71 is arranged on one side with the third belt clamp 78 in a stationary manner on the magazine frame 24, the relative displacement of the second drive belt 71 leads to a rolling movement around the third belt wheel 70 - here clockwise - the fourth belt wheel 72. The assembly bridge 54 and the with the assembly 54 coupled, inner guide rails 52A and 52B of the second inner, telescopic rail pair is moved in the extension direction S. The second drive belt 71 is consequently not set in motion directly, but only indirectly by the drive.

The movement coupling between the inner pair of telescopic rails 50 and the outer pair of telescopic rails 40 can be used in an analogous manner in order to couple a third pair of telescopic rails (not shown here) to the second pair of telescopic rails 50. In this way, an even further distance between the rest position and the discharge position could be bridged without the length of the telescopic rail arrangement 25 measured in the direction of movement S / R increasing.

Based on Figures 6 to 9 The movement of the conveyor member 31 from a rest position to a discharge position by means of the telescopic rail arrangement 25 will now be described. Figure 6 shows the rest position of the conveyor member 31 in the area of the storage space 27 of the magazine 18. The conveyor member is in this rest position 31 underneath a stack of edge protection means 19, not shown here, the lowermost edge protection means of the storage stack resting on the conveyor element 31.

In Figure 9 the conveyor element 31 assumes its discharge position, that is to say it has covered its maximum path of movement in the discharge direction or push-out direction S.

Figure 8 shows an intermediate position of the conveyor element 31 on its way in the direction of extension S between the rest position ( Figure 6 ) and outfeed position ( Figure 9 ).

In order to induce the extension movement in the extension direction S of the conveyor member 31, the drive, in particular the servomotor (not shown), is put into operation and the first belt wheel 60 is closed in the manner described above Figures 10 to 12 moved counterclockwise. As a result, the telescopic rail pairs 40 and 50 experience their extension movement in the extension direction S. The conveying member 31, which is movement-coupled to the second, inner telescopic rail pair 50 via the mounting bridge 54, follows this movement. It is moved from its rest position below the storage space 27 of the magazine 18 in the direction of extension S in the direction of the press plate and in the direction of the positioning device arranged there ( Figure 8 ) until it has reached its delivery position ( Figure 9 ). The conveyor member 31 transports a into the Figures 6 , 8th and 9 Edge protection agent, not shown, from the storage space 27 of the magazine 18 and brings it to the delivery position ( Figure 9 ) to transfer it to the positioning device (not shown). After the edge protection means 19 has been taken over by the positioning device, the servomotor is activated again, its direction of rotation being reversed. As a result, it now drives the first pulley 60 in a clockwise direction. As a result, the extended telescopic rails 42A, 42B, 50A, 50B, 51A, 51B are brought back into the rest position in the return direction R. Since the conveyor element 31 dips under the lowermost edge protection means 19 within the storage space 27 (edge protection means not shown) in order to convey this lowermost edge protection means 19 in the outfeed direction S when there is a renewed discharge movement.

The conveyor 31 is in the Figures 14 to 16 shown in different views. Figure 14 shows a plan view of the conveyor member 31 designed as a receiving plate 32.

It has a receiving surface 81 facing the storage space 27 or the edge protection means 19 arranged there and has a separating web 82 arranged at the end of the receiving surface facing away from the press plate to keep. In this respect, the cutout 83 can also be referred to as tool engagement. Opposite the cutout 83, the receiving surface 81 has a stop web 84. The edge protection means 19 rests against this with a longitudinal edge.

When the conveyor element 31 is in the discharge position, the positioning device moves towards the conveyor element 31 from a side facing away from the stop web 84. The gripping tool of the positioning device grips a region of the edge protection means that is exposed due to the cutout 83. The stop web 84 prevents the edge protection means 19 from being pushed down from the receiving surface 81 by the gripping tool of the positioning device.

In this context, be on Figure 16 referenced, which is a sectional view according to section line DD in Figure 14 shows and from which the stop web 84 delimiting the receiving surface 81 can be seen.

The structure and function of the separating web 82 can best be seen from Figure 15 explained. This is a longitudinal section of the conveyor element 31 according to section line CC in FIG Figure 14 . The separating web 32 initially has a to the receiving surface 81 or the resting there, in Figure 15 Not shown edge protection means pointing conveyor edge 85. The height of the conveyor edge 85 corresponds approximately to the thickness of an edge protection means 19 and engages on an edge of the edge protection means 19 to take it along in the outfeed direction S when the conveyor member 31 is moved into the outfeed position.

The rear side of the separating web 82 facing away from the press plate and pointing in the return direction R slopes down in a wedge shape, so that the inclined surface 86 resulting from this points upwards, i.e. in the direction of the edge protection means arranged in a stack in the storage space 27. With a retraction movement in the retraction direction R des The wedge-shaped design of the stop web 84 ensures that the conveyor element 31 is moved under the lowest edge protection means 19 located in the storage space 27 of the magazine 18, so that this bottom edge protection means 19 comes to rest on the receiving surface 81 when the conveyor element 31 is in the rest position .

As the description of the exemplary embodiment of the invention shows, the telescopic rails 40/50 make it possible to create a compact conveyor unit which moves the conveyor element 31 from a rest position to a discharge position and back again. The longer the distance to be overcome between the rest position and the discharge position, the more telescopic rails 40/50 are to be used. The exemplary embodiment shows impressively how these can be arranged, coupled to one another, below the storage space 27 within the magazine rack 24, without having to use an installation space that exceeds the base area of the magazine 18.

In addition to the minimization of installation space, another essential advantage is that the use of telescopic rails 40/50 considerably minimizes the masses to be moved and, as a result, the magazine 18 can be constructed more easily.

Finally, the use of telescopic rails makes it possible to use a drive that is new in this field of application, namely a belt drive. In combination with the small masses, this makes it possible to accelerate the outfeed and retraction movement and thus to carry out more strapping in a defined period of time.

The invention also proposes using a motor, in particular a servomotor, as the drive. The main advantage of the servomotor is that its sensors detect the rotational position of the motor shaft and thus precise control of the drive is possible. In addition, certain operating and wear states of the telescopic rail arrangement 25 can be recorded via the control electronics of the servomotor. For example, load peaks, which can be detected via voltage peaks or peaks in the current intensity, indicate briefly increased resistance to movement when the telescopic rails 40/50 are extended or retracted. These can wear bearings, drive belts 61/71 or Show belt pulleys 60/62/70/72. In connection with suitable communication modules, such measured values can be transmitted to a point responsible for maintenance. This can then replace defective parts in good time before machine failures as part of regular machine maintenance or preventive machine maintenance, so that a machine downtime and thus a failure is avoided.
