The present invention relates to a method of delivery, provision,

Handling and / or replacement of rolls with flat and / or foil material wound thereon and used as packaging material for packaging piece goods, containers or similar article assemblies within a packaging machine with the features of independent method claim 1. The invention also relates to a device for feeding, providing and / or handling and / or replacement of rolls with flat and / or sheet material wound thereon and used as packaging material for packaging piece goods, containers or similar article compositions

Characteristics of the independent claim 10. In a grouping and compilation of articles to containers, eg. Beverage containers o. The like., These are often held together in practice by shrink film to slipping or loosening from the compilation during further handling or to prevent during transport. For example, containers comprising four, six or more containers are known from the prior art. Such containers form a very common variant of sales units for beverage containers or bottles made of PET plastic. In order to achieve a high throughput in packaging and / or in a subsequent palletizing, the fastest possible compilation of such containers without interruption is individual

Process steps desirable. In order to make the packaging material or the shrink film for partial or complete wrapping container available, devices and methods are already known, which unwind the material of a roll or multiple roles to carry within a packaging machine and thus the individual containers or the respective Cover the packaging material with articles intended to form the respective container. The unwinding of the packaging material from the roll is usually done by machine and can be done in a continuous process. Devices are known in which the packaging material is withdrawn via rollers from the rotating roll. Is a roll settled and stock up If the packaging material of the roll is exhausted, an exchange of the respective roll or a replacement by a new roll must take place. However, with such a

Reel change an undesirable interruption of the process of putting together and packaging of containers connected. A method and a device by means of which new rolls can be delivered and used rolls can be exchanged within a packaging machine are known, for example, from DE 40 40 545 A1. This known device has a plurality of supply rolls with strip material, which are arranged side by side. The core of the rollers is placed in each case on a common pin. A beginning of the

Strip material is previously connected to a roller, which pulls the strip material from the respective roll and leads away from the device in the downward direction. In order to operate this known device and to unwind the material from the roll, the role must be placed with its core in conformity with the direction of rotation on the pin. The strip material or the first layer of the strip material must descend from above in the direction of the rolls. If the roller with opposite direction of rotation placed on the pin, so could

Strip material is difficult or impossible to be removed from the roll, which would complicate the process. Depending on the direction of rotation of the attached new roles in these known devices, a manual reacting and rotationally compliant re-placement is indispensable to ensure trouble-free operation can.

Devices for automatically feeding material wound on rolls and for replacing worn rolls in processing or

Packaging machines are also known in different embodiments, so for example. By devices for feeding and changing coils with strip material in a processing machine according to DE 32 02 647 A1 or DE 41 42 256 A1.

DE 34 25 734 A1 discloses an automated system for the supply of packaging material on production and / or packaging lines. The system comprises a magazine for the packaging material and a carriage equipped with an articulated arm for gripping the packaging material and feeding it to the processing machines located on the processing lines. The trolley with the articulated arm travels along routes that are determined by a computer connected to the processing machines. A device for supplying packaging machines with consumable or packaging material is also known from EP 1 273 541 B1. The wound as reels of material webs are delivered on pallets and distributed to several manufacturing and packaging machines, the pallets first by means of

Pallet conveyors are brought into interim storage, while individual reels are removed by separate Bobinenförderer and transported to a machine to be supplied.

DE 10 2006 017 379 A1 discloses a device for handling reels of packaging material. The device comprises a reel storage with a portal in which the reels are held on pallets. A gantry robot with

Knickarm handed Bobinen as needed to au outside the portal arranged

Reeling systems. Of these, the webs are transported to opposite sides in the direction parallel to the longitudinal extent of the portal to the consumption machines. As a rule, the known handling methods and devices require exact positioning and feeding of new reels or reels with packaging material wound thereon. If this exact positioning can not be guaranteed, the smooth replacement of worn-out rollers is endangered, as a result of which the functionality of the packaging machine is no longer sufficient

In the following, some aspects, peculiarities and details of the method according to the invention and of the device according to the invention will be described again

summarized. Thus, the invention relates to a method for handling wound on rolls and as packaging material of piece goods, containers or similar article compositions serving flat and / or sheet material. The flat and / or sheet material may be formed as a shrink film or as a conventional plastic film. The rollers may have a core whose geometric shape corresponds to a hollow cylinder and which may consist at least partially of cellulose-containing material. Advantageously, the respective new role hereby on a pin corresponding to the core of the

Packaging machine are placed and when removing or removal

Rotate the packaging material from the roll, rotating it on the spigot. As part of the process at least partially unwound and / or exhausted rolls are removed from at least one installation position of a packaging machine and then each used a new role with flat and / or sheet material in the respective installation position. In preferred embodiments, at least two different mounting positions may be provided. Each of the at least two mounting positions can, as previously mentioned, have a pin on which the new roller is placed and on which the respective roller rotates to unwind its respective flat and / or sheet material. In particular, the rollers can be fixed in a clamping manner on the journal of their respective installation position. The pin can be driven in rotation and transmit torque to the respective seated roller so that the roller is moved in rotation about its pin to unwind its flat and / or sheet material. Each pin can be assigned a drive over which the respective pin is rotated. The drives can be closer with one below described control unit are in communication or be controlled via a control unit described in more detail below for rotating the pin. Before removing a roll with at least partially unwound and / or used up packaging material from their respective installation position, the clamping

Connection between the pin and the roller can be solved so that the role is then no longer firmly connected to the pin and can be removed from the pin. The rotating movement of the pin can be interrupted until a new roll is placed on the pin or inserted into the corresponding installation position. After each insertion of a new role in their respective

Installation position is usually deducted an out- lying position of the respective new role in the vicinity or in the region of its free end and connected to form a continuous web of material with a portion of a guided in the packaging machine web of another role.

The outboard ply of the respective inserted new roll may, after insertion with a suitable gripping element, e.g. be withdrawn by means of a pneumatic suction, mechanical clamping and / or electrostatically adhesive working gripping and / or handling device, which moves back and forth between the at least two mounting positions. Thus, the gripping member can alternately deduct from the at least two mounting positions outsides lying layers of new roles. In practice, embodiments have proven in which the gripping element temporarily fixes the respective outer layer of a new roll on vacuum. Further, a welding rod may be provided, which is moved in the downward direction and in this case the outer layer of the respective new roll welded to the guided in the packaging machine material web. About the gripping element, the respective outer layer can be moved into a working area of the welding rod. The temperature-controlled welding rod can thus the outer-lying position of each new role clamped against the in the

Moving packaging machine guided material web. In particular, embodiments have proven in which the welding rod for this purpose is moved vertically up and down and welded in a vertical lowering movement, the respective outer lying position of a new role with a guided in the packaging machine web.

Normally, during the insertion of a new roll and during the joining, the flat and / or sheet material of the further roll is not yet completely unwound. Advantageously, the new role in conceivable embodiments Accordingly, while from the other role in the

Packaging machine still continuous flat and / or sheet material is handled. Flat and / or film material can be unwound from a further roll of the packaging machine even when removing an at least approximately completely unwound and / or used up roll from the packaging machine It is conceivable that flat and / or sheet material of at least one in the packaging machine positioned roll is unwound. Also, it may be that at the time of joining the flat and / or

Foil material of a new roll with already in the packaging machine guided or recorded flat and / or sheet material no flat and / or sheet material of recorded in the at least two mounting positions roles is handled.

In the method described with the present invention, at least approximately unwound and / or applied rollers are detected by sensors and replaced by new roles with flat and / or sheet material by means of the previously described gripping and / or handling device. A sensory recognition, for example, with the aid of optical detectors or an optical

Detection system take place, which can be arranged in the region of at least one mounting position. The optical detection system or the optical detector and the gripping and / or handling device can be connected to the control unit, which also controls the movements of the gripping and / or handling device or of the multi-axis robot.

In addition, during or before the onset of the new roll, its direction of rotation and / or orientation in conformity with the direction of rotation can be detected and / or checked. In practice, in particular embodiments have proven in which the determination and / or checking the direction of rotation and / or direction of rotation conforming orientation by means of optical detection. However, the invention is not limited to such embodiments, so that, for example, haptic and / or other mechanisms may be provided to check the direction of rotation and / or direction of rotation conforming orientation of the respective new role. Is the detected direction of rotation and / or direction of rotation compliant orientation suitable or

If this corresponds to a predetermined desired orientation and / or desired direction of rotation, then the respective new roller can be inserted into its assigned installation position or remain in its respective assigned installation position. Will be wrong

Direction of rotation and / or found a wrong direction of rotation compliant positioning, so an alignment correction of the respective new role made or a Another new roller with suitable direction of rotation and / or orientation suitable for insertion selected and used in the respective installation position. This can be inventively using the above described

Clipboard done, which is located in the vicinity of the gripping and / or handling device or at least within their range of motion.

So it may be that a direction of rotation and / or directionally compliant

Positioning a new role is checked. If an incorrect direction of rotation and / or a wrong direction of rotation compliant positioning has been determined, then the respective new roll before insertion into the packaging machine on the

Laying placed clipboard, separated from the gripping and / or handling device and oriented towards the direction or oriented with a suitable direction of rotation or aligned resumed and then be used in their respective installation position. The direction of rotation conforming orientation or the orientation with the appropriate direction of rotation and the insertion of the role in their respective mounting position can then be done before connecting or welding their outer layer with the remaining material in the packaging machine web.

The schematic perspective view of Fig. 1 shows a first

Embodiment variant of a device according to the invention 10. In addition, Fig. 1 also illustrates a conceivable implementation of an embodiment of the inventive method described above.

The device 10 is used to handle flat packaging material such as shrink film or packaging films, which is wound on large, due to their weight usually not manually manageable rollers 12. Schematically indicated in Fig. 1 is a part of a packaging machine 14, which has a

to be described in more detail below gripping and / or handling device 16 new rollers 12 are supplied. The gripping and / or handling device 16 embodied as a stationary arranged multi-axis robot 18 in the exemplary embodiment shown uses the respective new rolls 12 to be supplied to the packaging machine 14 in two different installation positions EB1 and EB2, which are only partially recognizable in FIG. 1 and in the detailed view of Fig. 4 are exemplified.

The clipboard 60 which forms an important part of the invention and serves to align the new rollers 12 to be used in the packaging machine 14 in the direction of rotation, is not shown in the illustration of FIG. 1, but only in the illustration of FIG FIGS. 4 to 6 with FIGS. 1 and 2 show, by means of the gripping and / or handling device 16 or with the aid of the multi-axis or handling robot 18, individual new rollers 12 in one of the two installation positions EB1 and EB2, while in FIG the further installation position EB2 or EB1 is still a spent or partially used role 20, of which even during the onset of each new roll 12 is still a material web located thereon 22 is unwound, which is processed in the packaging machine 14 as packaging material. During the further Abwickeins the

Material web 22 of the nearly applied roller 20 is a compound or Welding of the outer layer 24 (see Fig. 6) of the new roll 12 with the web 22, whereby the device 10 can run in a continuous operation, without the packaging process would have to be interrupted for replacing an applied roll 20 against a new roll 12 , The new rolls 12 are each composed of the wound-up flat packaging material 22 or of the packaging or shrink film and a core 26 on which the packaging material 22 or the shrink film is wound up. To receive a new roll 12 from one in FIG. 1

indicated horizontal conveyor 28 dives the handling device 16 and the handling robot 18 via a movable end of his movable arm 30 movably arranged holding mandrel 32 frontally into a core 26 of a new roll 12 a. An arm section 34 of the handling device 16 or of the handling robot 18 can for this purpose be rotated about an axis of rotation 36, as shown by way of example in FIG. 7A. After immersing the retaining mandrel 32 in the core 26 of the

Cross-sectional diameter of the retaining mandrel 32 is increased, so that the new roller 12, as shown in Fig. 7B, is fixed to the retaining mandrel 32 by clamping. The core 26 is

hollow cylindrical, the shape of the retaining mandrel 32 corresponding thereto, so that the retaining mandrel 32 for clamping fixation of the new roll 12 via its

Outer circumference with an inner circumferential surface of the core 26 is in communication. About the horizontal conveyor 28 of the gripping and / or

Handling device 16 and the handling robot 18 new rolls 12 are provided in an uninterrupted sequence, so that when removing a new roll 12 from the horizontal conveyor 28 another new role 12 in the direction of the handling device 16 is moved or in the direction of gripping and / or handling device 16 moves. The horizontal conveyor 28 can be clocked as needed in the desired manner or continuously with constant

Speed operated. Their operation is dictated by a control unit 38, which is only schematically indicated here and which not only controls the

Horizontal conveyor 28 controls in its conveying speed and / or timing, but also the handling robot 18 in its movements. The control unit 38 processes the signals 40 of at least one room monitoring device 42, which may be formed in particular by an optical detection device or a camera 44, possibly also by a plurality of cameras 44, which detect at least the movement space 46 of the multi-axis robot 18 and its movements, including the exact movements of the boom 30 with the pivotally mounted thereto Holding mandrel 32 with respect to each to be detected new role 12 are meant. The movement space 46, which can be detected optically by means of the space monitoring device 42 formed by the camera 44, is indicated in the representation of FIG. 1 for better illustration by a fan beam with the broken lines. In Fig. 1 can be seen further in the region of the horizontal conveyor

28 positioned manipulator 48 which is operated by a user 50 and over which new rolls 12 can be placed standing on the horizontal conveyor 28. The new rollers 12 can, for example, be delivered standing on a pallet 52, from which they are received by the user 50 by means of the manipulator 48 that can be controlled by him in his movements and by means of a manipulator 48 located there

Holding mandrel 54 can place on the horizontal conveyor 28. A working area of the manipulator 48 therefore extends over the pallet 52 as well as over one

Section of the horizontal conveyor 28. However, this control and Zufördervariante shown represents only one example of many alternatives. Also possible are continuous Zufördervarianten that require no manual handling, as described with reference to FIG. 1. In a not ordered in this way feed, it makes sense in the movement space 46 of the gripping and

Handling device 16 to provide a clipboard for the new rollers 12 to non-directional detection by the retaining mandrel 32 of the

Handling robot 18 to be able to put the rollers 12 there, the retaining mandrel 32 to pull out of the core 26 and to detect the role 12 at its other end again to use them in the required direction of rotation for the mounting positions EB1 or EB2 in the packaging machine 14 , Such a clipboard, its function and its interaction with the gripping and / or handling device 16 and with the room monitoring device 42 are exemplary based on

Embodiment of Fig. 2 explained in more detail. In the variant of the device 10 shown in FIG. 1, this clipboard 60 is not drawn, but nevertheless an important component of the device 10.

Fig. 1 also shows an open-topped container 56, located in the

Work area 46 of the gripping and / or handling device 16 is located. If the supply of packaging material or shrink film of a roller 12 or 20 placed in the packaging machine 14 is exhausted, by means of the handling robot 18 the core 26 of cellulose, plastic, wood or cardboard is taken out of the packaging machine 14 and empty Container 56 stored. Only after removal of the core 26, a new roller 12 in the respective installation position EB1 or EB2 of the packaging machine 14 are used, so that the gripping and / or handling device 16 and the handling robot 18 first removes the core 26 and temporally subsequent thereto uses a new roll 12 in the respective installation position EB1 and EB2. As already mentioned, the horizontal conveyor 28, the gripping and / or

Handling device 16 or the multi-axis robot 18 and the packaging machine 14 in conjunction with the control unit 38. The same applies to the clipboard 60 (see Fig. 2). This control unit 38 can in particular specify the clocked operation of the horizontal conveyor 28, initiate insertion and removal of rollers 12 and 20 by the handling device 16 from the two installation positions EB1 and EB2. In addition, it can, as described in more detail below, a unwinding of packaging material or shrink film of the rollers 12 used in the packaging machine 14 control. Substantially in the context of the present

Invention is also that the room monitoring device 42 in

Cooperation with the control unit 38, a movement control of

Horizontal conveyor 28 and in particular the gripping and / or

Handling device 16 enable the fault-tolerant positioning and feeding of the new rollers 12 and their handling, since the exact detection of each new roll 12 by the retaining mandrel 32 of the handling robot 18 by means of at least one camera 44 can be effectively supported and controlled, so that the exact positioning of the rollers 12 on the horizontal conveyor 28 loses importance and can be compensated by the correspondingly tracked motion control of the handling robot 18 within its movement space 46. The indicated in Fig. 1 positioning of the camera 44 is merely exemplary understood. Likewise, a camera 44 or several cameras 44 may be positioned at other locations, for example also in the area of the packaging machine 14, in the area of the handling robot 18 or possibly even on its pivot arm 30, provided that the movement space 46 is covered in the required manner and can be detected.

The control unit 38 can also have a display device 58 or a display via which / information about the direction of rotation or

Direction of rotation conforming orientation of new rollers 12 and / or other control or movement parameters of the multi-axis robot 18 and / or the horizontal conveyor 28 can be visualized for the user 50. The direction of rotation or rotational direction-conforming orientation of the new rollers 12 is preferably determined and / or checked by the camera 44 or possibly also by a further camera, as described below by way of example with reference to FIGS. 4 to 6, with the control unit 38 in FIG Connection is or stand. Since the gripping and / or

Handling device 16 can remove the respective core 26 of an empty roll 20 from the packaging machine 14 and with the help of the camera 44 and the other cameras new roles 12 with matching direction of rotation or with

Direction of rotation conforming orientation in the packaging machine 14selb used, the device 10 can be operated fully automated at least from the beginning of receiving new rolls 12 of the horizontal conveyor 28.

The schematic perspective view of Fig. 2 illustrates a second

Embodiment of the device 10 according to the invention as well as a meaningful

Implementation of an embodiment of the inventive method. The

Packaging machine 14 does not differ significantly from the previous one

variant described in FIG. 1. Again, the device 10 in turn serves the handling of flat packaging material such as. Shrink film or

Packaging films, the packaging machine 14 according to the

consumption-related replenishment requirements are made available individually on rollers 12 by means of the gripping and / or handling device 16 embodied as a multi-axis robot 18. As in the first variant of FIG. 1 sets the gripping and / or

Handling device 16, the new rollers 12 to be supplied in each case to the packaging machine 14 into two different installation positions EB1 and EB2, which are explained in more detail with reference to the detailed views of FIGS. 4 to 6. The second variant of the device 10 shown in FIG. 2 dispenses with one

Horizontal conveyor, but gets the new rollers 12 each supplied to pallets 52, wherein on each pallet 52 four vertically arranged rollers 12 are each received individually by the handling robot 18 and in the

Packaging machine 14 are used. To accommodate a new roll 12 from one of the in-range, i. within the movement space 46 of the gripping and / or

Handling device 16 or the multi-axis robot 18 standing pallets 52 dives the handling device 16 and the handling robot 18 on the end of his movable boom 30 movably arranged holding mandrel 32 frontally into a core 26 of a new roll 12, as already described with reference to FIG was explained. An arm portion 34 of the handling device 16 and the For this purpose, handling robot 18 can be rotated about an axis of rotation 36, as shown by way of example in FIG. 7A. After immersing the retaining mandrel 32 in the core 26, the cross-sectional diameter of the retaining mandrel 32 is increased, so that the new roller 12, as shown in Fig. 7B, is fixed to the retaining mandrel 32 by clamping. The core 26 is hollow cylindrical, the shape of the retaining mandrel 32 thereto

Corresponding, so that the holding mandrel 32 for clamping fixation of the new roller 12 via its Au ßenumfang with an inner circumferential surface of the core 26 is in communication.

About the regularly supplied in the movement space 46 pallets 52, each with four new rollers 12 of the gripping and / or handling device 16 and the handling robot 18 new rolls 12 are provided in an uninterrupted sequence available, so that upon removal of all new rolls 12 of a the pallets 52 this empty pallet 52 can be exchanged for a new pallet 52 with another four rollers 12, which in turn in the movement space 46 of the gripping and / or

Handling device is to place. This delivery can take place by means of suitable industrial trucks, for example by means of so-called FTS (driverless transport systems), which are formed by self-propelled, remotely controlled and / or own sensor systems for steering transport vehicles, for example. Each a pallet 52 with rollers 12 placed in it can move the movement space 46. These

Transport systems or FTS can be operated clocked as desired in the desired manner. Their operation is preferably predetermined by the schematically indicated control unit 38, which not only controls the FTS (not shown here) in its conveying speed and / or timing, but also controls the handling robot 18 in its movements to replace the rollers 12 in the packaging machine 14. The control unit 38 also processes the signals 40 of at least one room monitoring device 42, which may also be formed in the variant of FIG. 2, in particular by an optical detection device or a camera 44, possibly also by a plurality of cameras 44, at least the movement space 46 of

Multi-axis robot 18 and detect its movements, which also the exact

Movements of the cantilever arm 30 with the pivoting mandrel 32 pivotally mounted thereto are meant with respect to each new roller 12 to be detected. The movement space 46, which can be detected optically by means of the space monitoring device 42 formed by the camera 44, is indicated in the representation of FIG. 1 by an ellipse with interrupted ruling. Because of the sufficiently dimensioned movement space 46, not only the horizontal conveyor can be dispensed with in the variant of the device according to FIG. 2, but also the manipulator interacting therewith, via which new rollers 12 can be placed standing on the horizontal conveyor (cf. FIG. 1 ). In contrast, in Fig. 2 in the movement space 46 of the gripping and handling device 16 and in the immediate vicinity of a clipboard 60 for the new rollers 12 can be seen, which serves in the normally unclassified on the pallets 52 direction of rotation of the rollers 12, the indispensable

Directionally correct positioning of each roller 12 when inserted into the

To ensure packaging machine 14. In practice, the retaining mandrel 32 of the handling robot 18 detects each individual roller 12, which stands on the pallet 52, without the direction of rotation already being checked. By suitable optical control or by detection in any other way (eg inductively, by means of transponders or the like) is checked during the movement of the cantilever arm 30 with the carried on the retaining mandrel 32 roller 12 in the direction of the packaging machine 14, whether the roller 12 there and directly can be positioned without repositioning or if the roller 12 may have the wrong direction of rotation. If this is the case, the roller 12 by a corresponding movement control of the handling robot 18 on the

Clipboard 60 are stored, after which the retaining mandrel 32 is pulled out of the core 26 of the stored roll 12 to detect the role 12 at its other end again to then in each required direction of rotation for the mounting positions EB1 or EB2 in the packaging machine 14th to be able to use. The design of the clipboard 60, their exact function and their interaction with the gripping and / or handling device 16 and with the

Room monitoring device 42 are explained in more detail by way of example with reference to the embodiment of FIG. 2 and the detailed views of FIG. 3.

The standing in Fig. 2 within the movement space 46 user 50 usually holds there only for maintenance purposes, but not during operation of the gripping and / or handling device, which possibly also by the

Room monitoring device 42 can be controlled.

Also in Fig. 2, the open-topped container 56 can be seen, located in the

Work area 46 of the gripping and / or handling device 16 is located. Is the supply of packaging material or shrink film of a placed in the packaging machine 14 rolls 12 and 20 exhausted, by means of handling robot 18 of existing cellulose, plastic, wood or cardboard core 26 of an empty roll 20 from the Packing machine 14 removed and stored in the container 56. Only after removal of the core 26, a new roll 12 can be used in the respective installation position EB1 or EB2 of the packaging machine 14, so that the gripping and / or handling device 16 and the handling robot 18 first removes the core 26 and temporally following a insert new roller 12 in the respective installation position EB1 or EB2.

As already mentioned, the gripping and / or handling device 16 or the multi-axis robot 18, the controllable clipboard 60 for the rollers 12 and the packaging machine 14 are in communication with the control unit 38, which can be supplied to the FTS, which is optionally not shown here of the pallets 52 can control. The control unit 38 can thus specify in particular the timed operation of the FTS, insertion and removal of rollers 12 and 20 by the

Handling device 16 from the two installation positions EB1 and EB2 initiate, and if necessary to use the clipboard 60 to ensure the correct direction of rotation of a new roll 12 to be used. In addition, it can, as described in more detail below, a unwinding of packaging material or shrink film of the rollers 12 used in the packaging machine 14 control. Substantially in the context of the present invention, for example, that the room monitoring device 42 in cooperation with the control unit 38, a movement control of the gripping and / or handling device 16 under need of inclusion

Clipboard 60 allows creating a fault-tolerant positioning and

Delivery of the new rollers 12 on the not exactly positioned pallets 52 and the handling of the recorded rollers 12 is made possible because the exact detection of each new roll 12 by the retaining mandrel 32 of the handling robot 18 with the help of at least one camera 44 can be effectively supported and controlled , so that the exact positioning of the rollers 12 on the pallets 52 or the pallets 52 even on the ground in the area of the movement space 46 loses importance and can be compensated for by the appropriately tracked motion control of the handling robot 18 within its movement space 46. The indicated in Fig. 2 positioning of the camera 44 is merely exemplary understood. Likewise, a camera 44 or several cameras 44 may be positioned at further locations, for example also in the area of the packaging machine 14, in the area of the handling robot 18 or optionally also on its pivot arm 30, provided that the movement space 46 is covered in the required manner and can be detected. The camera 44 or the room monitoring device 42 then serves its purpose fulfill in an optimal manner, if they can cover the movement space 46 largely completely and if they are the movements of the gripping and / or

Handling device 16, its retaining mandrel 32 and the various target positions of the retaining mandrel 32 during recording and positioning of the rollers 12 can accurately detect and track. To ensure this reliably, it may be useful if the rollers 12, but at least the retaining mandrel 32, optionally also the pivot arm 30 of the handling robot 18 are provided with suitable reference marks that can be formed, for example, by visually uniquely recognizable in space marks, so that they can serve the camera system 44 as clearly recognizable and spatially assignable markings.

Direction of rotation conforming orientation new roles 12 and / or other control or movement parameters of the multi-axis robot 18 and / or the FTS for the user 50 can be visualized. The direction of rotation or rotational direction-conforming orientation of the new rollers 12 is preferably determined and / or checked by the camera 44 or possibly also by a further camera, as described below by way of example with reference to FIGS. 4 to 6, with the control unit 38 in FIG Connection is or stand. Since the gripping and / or handling device 16 can remove the respective core 26 of an empty roll 20 from the packaging machine 14 and with the help of the camera 44 and the other cameras new roles 12 with matching direction of rotation or with direction of rotation in the orientation

Packaging machine 14 uses independent, the device 10, at least from the beginning of receiving new rolls 12 of the respective pallet 52nd

be operated largely automated.

With reference to Figures 1 and 2 is added at this point that the gripping and / or handling device 16 shown or the latter forming this

Handling robot 18 could optionally be present in double or triple version, provided that the movement spaces 46 of the two or more

Handling robot 18 are matched to one another in a way that there can be no collisions. Since, however, a longer uninterrupted operation is normally ensured due to the web lengths on the rollers 12, the rollers 12 do not have to be replaced so frequently that the use of two or more handling robots 18 would be necessary for this purpose. However, a useful embodiment variant can provide that a gripping and / or handling device 16 or a single handling robot 18 can supply two packaging lines or two packaging machines 14, wherein the movement space 46 is expediently located between the two packaging machines 14 arranged approximately parallel to one another that also the feed area for new rolls 12 with the horizontal conveyor 28 (see Fig. 1) and the

Pallet delivery (see Fig. 2) between the two packaging machines 14 and in the vicinity of the handling robot 18 and within its movement space 46 is located. In this case, the handling robot 18 can alternately supply the two normally operating packaging machines 14 with new rolls 12 and, if necessary, transfer the used rolls 20 into a common container 56 for subsequent or cyclical disposal. If the movement space 46 can not be monitored with a single camera 44 because it is partially shaded, for example, several cameras 44 may be present for monitoring the space.

FIG. 3 shows a total of seven schematic views of the clipboard 60, as used in both variants of the device 10 according to FIG. 1 and FIG. 2, when the direction of rotation of the roller 12 does not occur after being picked up by the holding mandrel 32 of the handling robot 18 for the intended installation position in the

Packaging machine 14 is right. In this case, the handling robot 18 sets the roller 12 onto the prism-like (see Figures 3A to 3C) upper support surface 62 of the arranged in the movement space 46 clipboard 60 by appropriate pivoting movement of its multi-axially movable arm 30, pulls the retaining pin 32 from the roller core 26 and leads him on the opposite end of the roll 12 back into the roll core 26 a. After fixing the roller 12 on the retaining mandrel 32 of this can take up the roller 12 by corresponding movement of the boom 30 and insert it into the intended installation position of the packaging machine 14.

The first variant of the clipboard 60 shown in FIGS. 3A to 3C with the prism-like upper bearing surface 62 ensures the exact central positioning of the roller 12 during depositing and prevents its lateral rolling or twisting. Optionally, the upper support surface 62 may also be formed as shown in FIG. 3D by a plurality of parallel rollers 94 which are arranged in a row, that the juxtaposed inner rollers 94 are lower than the higher two externa ßeren rollers 94. This arrangement the rollers 94 allows the exact Storage of a new roll 12, which can be stored there by means of the handling robot 18 (see Fig. 3E). At least one of these rollers 94, which are rotatably mounted in vertical frame plates 96 front side, may be provided with a drive to rotate the roller 12 by a defined angular amount about its longitudinal axis, for example. To bring a web edge in a desired position, the favorable for the removal of this material web edge after insertion of the role in the right one

Installation position in the packaging machine 14 is. These drives can in particular be formed by the illustrated rollers 94 according to FIGS. 3D to 3G, which are integrated in the support surface 62 or which form this support surface 62. However, the optional drives are not shown in detail in the illustrations of FIGS. 3A to 3C, but only in the illustrations of FIGS. 3D to 3G.

As is the perspective views of Figures 3A, 3D, 3E and 3F, the

Front views of Figures 3B and 3G as well as the top view of FIG. 3C reveals the clipboard 60 is formed as a bearing block 64, which may optionally be anchored fixedly on the ground in the region of the movement space 46. However, embodiments are also possible with movable bearing block 64, which can be rotated, for example, about a vertical central axis 66 (see Fig. 3C) to adjust the direction of rotation of the roller 12 in the desired manner or to the roller 12 in the desired manner for the recovery by the retaining pin 32 of the

Positioning robot 18 to position.

Moreover, the clipboard 60 or the bearing block 64 can be assigned suitable optical detection means, such as a camera or the like, which is preferably coupled to the control unit 38 (see Fig. 2), so that the exact positioning of one on the support surface 62 located roller 12 whose orientation and the sense of rotation or angle of rotation can be checked and recorded to the

Handling robot 18 and / or the optional drives, turning mechanisms, etc. of the clipboard 60 to control.

A further option may provide that the clipboard 60 as a whole is movable, for example, if it is also designed as a so-called. FTS (driverless transport system). Preferably, it can in this variant in their movements and

Rotations within the movement space 46 are also controlled by the control unit 38, typically in reasonable coordination with the handling robot 18, which may be useful in particular to speed up the change processes of the rollers 12. FIGS. 3A to 3G also show clamping jaws 68 which can press on both sides on the end faces of a roller 12 placed on the support surface 62, provided that they are delivered there to both end faces of the roller 12. In this way, after lateral delivery of the jaws 68, the roller 12 are held in position until the retainer mandrel 32 has been retracted to re-take the roller 12 in the roller core 26 and fixed there, so that the roller 12 in the

Installation position in the packaging machine 14 can be transported. The delivery drive and mechanism 98 for the jaws 68 deliverable or revealable in the direction of longitudinal extension of the rollers 94 can be seen in FIGS. 3D and 3E and is located underneath the rollers 94 and abuts on both sides

Bound frame plates 96, which form the bearing part of the bearing block 64 in this embodiment variant.

The schematic perspective view of Fig. 3E illustrates the process of depositing a new roll 12 on the rotatable and drivable rollers 94, which form the trough-shaped upper bearing surface 62 of the bearing block 64. The roll 12 is deposited by means of the handling robot 18 on the clipboard 60, after which the retaining mandrel 32 is pulled out of the roll core 26 at the end of the gripping arm 34, the roll 12 is rotated in the desired manner by means of the rollers 94 and / or by means of the deliverable clamping jaws 68 in the axial direction Direction on the support surface 62 can be positioned.

The schematic perspective view of Fig. 3F and the schematic

Front view of Fig. 3G illustrate a further embodiment of the

Clipboard 60, in which instead of the two parallel frame plates 96 (see Figures 3D and 3E), a closed housing 100 for receiving and supporting the rollers 94 and the adjustable jaws 68 together with their ZuStellantrieb and / or

Delivery mechanism 98 is provided. The remaining construction of the clipboard 60 according to FIGS. 3F and 3G largely corresponds to the variant according to FIGS. 3D and 3E.

The schematic perspective view of Fig. 4 illustrates the previously mentioned mounting positions EB1 and EB2 for the rollers 12, which in the

Packaging machine 14 according to the variants according to FIG. 1 and / or Fig. 2 are defined. Each of the mounting positions EB1 and EB2 is defined by its own rotatable mandrel 70. On each of these two horizontally oriented

The mandrels 70 are each a new role 12 attached by means of the gripping and / or handling device (see Figures 1 and 2) and by means of magnification of the Diameter of the mandrels 70 fixed by clamping the roller core 26 on the respective mandrel 70 by clamping. The Fig. 4 also leaves a

Welding bar 72, which for connecting an outer layer 24 (see Fig. 5, Fig. 6) of the inserted into the respective mounting position EB1 and EB2 new roller 12 (see Fig. 5) with the remaining material in the packaging machine 14 material web 22 is provided and this is lowered vertically. After joining the outer layer 24 (see Fig. 5) with the material web 22 remaining in the packaging machine 14, the tempered welding bar 72 is lifted vertically and brought into the position shown in FIG. In the illustration of FIG. 4, in the first installation position EB1, a virtually worn-out roller 20 rests on the receiving mandrel 70 of the first installation position EB1 and is moved in rotation by the mandrel 70 or by the removal of the material web 22. In this case, the packaging material or the shrink film of the seated on the mandrel 70 of the first installation position EB1 roller 20 is unwound. In the second

In the installation position EB2, a used-up roller 20 has already been completely unwound and the core 26 (see Figures 1 and 2) removed via the handling device 16, so that the second mounting position EB2 and the receiving mandrel 70 of the second

Installation position EB2 ready for receiving a new roll 12 with packaging material. Each of the mounting positions EB1 and EB2 may be associated with a separate sensor system or camera 74, by means of which at least approximately fully developed and / or used-up rollers 20 can be optically detected. If a roll 20 is at least approximately completely processed and / or used up, the respective camera 74 sends information about the respective at least approximately completely processed and / or used roll 20 to the control unit 38. The previously mentioned control unit 38 controls on the basis of numerous data so also the cameras 74 within the

Packaging machine 14, the gripping and / or handling device 18 and the handling robot 18 (see Figures 1 and 2) for removing the respective at least approximately completely unwound and / or applied roller 20 or for removing the core 26 of the respective at least approximately completely

unwound and / or used-up roll 20. Thus, the at least approximately completely settled and / or exhausted role 20 from their respective

Installation position EB1 or EB2 can be removed, a previously formed between the respective roller 20 and the mandrel 70 clamping end Connection solved. This is typically done by reducing the cross-sectional diameter of the respective mandrel 70, whereby the

Pull off core core 26. The release of the clamping connection or the

Reduction of the cross-sectional diameter of the receiving mandrels 70 is further specified by the control unit 38.

To remove the at least approximately completely unwound and / or depleted roller 20 from its respective installation position EB1 or EB2, the gripping and / or handling device 16 dives into the core 26 of the at least approximately completely unwound via its retaining mandrel 32 (see FIG and or

spent roll 20 a. By enlarging the cross-sectional diameter of the receiving mandrel 70, the respective at least approximately completely unwound and / or spent roll 20 is then fixed to the retaining mandrel 32 of the handling device 16. An increase in the cross-sectional diameter of the retaining mandrel 32 for clamping the roller 20 and the roller core 26 is also on the

Control unit 38 predetermined. After fixing the at least approximately completely unwound and / or applied roll 20 on the retaining mandrel 32, the at least approximately completely unwound and / or depleted roll 20 by means of gripping and / or handling device 16 and under specification by the

Control unit 38 in the direction of the container 56 (see Figures 1 and 2) moves and stored there by reducing the cross-sectional diameter of the retaining mandrel 32.

After depositing the at least approximately completely unwound and / or applied roll 20 or the core 26 in the container 56 (see Figures 1 and 2), the gripping and / or handling device 16 via the control unit 38 for

Insertion of a new roll 12 in the respective installation position EB1 or EB2 within the packaging machine 14 driven. Previously, a check of the direction of rotation or direction of rotation conforming orientation of the respective new roll 12 - preferably with the aid of the clipboard 60 and the bearing block 64 (see Fig. 3), as previously described - take place. The device 10 can be operated in this way automated. It should be mentioned at this point that the exemplary embodiment according to FIG. 4 is to be understood merely as an example, so that further embodiments can be envisaged in which two mounting positions EB1 and EB2 only one camera 74 is assigned whose detection range is determined by the two mounting positions EB1 and EB1 EB2 extends. It is also possible, via the cameras 74, to check a direction of rotation or directions of rotation of new rollers 12 inserted into the installation positions EB1 and EB2. Became a wrong one Direction of rotation or direction of rotation conforming orientation of new rollers 12 detected in one of the two installation positions EB1 and EB2, so can be caused via the control unit 38, an alignment correction of the respective new roll 12 via the gripping and / or handling device 16. This can then remove the respective new roller 12 from its respective installation position EB1 or EB2, to which

Store the roll 12 with the appropriate direction of rotation and / or orientation in conformity with the direction of rotation and then re-insert it into its respective installation position EB1 or EB2 with the appropriate direction of rotation and / or direction of orientation. The further schematic perspective view of FIG. 5 shows the

Installation positions EB1 and EB2 corresponding to FIG. 4 with inserted new roller 12 for the second mounting position EB2. 4, a new roller 12 has been pushed onto the receiving mandrel 70 of the second installation position EB2 by means of the gripping and / or handling device 16 (compare FIGS. 1 and 2) in the representation of FIG. Furthermore, packaging material 22 or shrink film of the nearly used or developed and therefore soon to be removed role 20 of the first

Installation position EB1 unwound, so that the packaging machine 14 (see Figures 1 and 2) can be operated even when replacing the roller 20 from the first installation position by switching to the new roll 12 of the second mounting position EB2. If a new roll 12 is then subsequently inserted into the first installation position EB1, then packaging material 22 or shrink film can be unwound from the roll 12 of the second installation position EB2, whereby the required continuous and uninterrupted operation of the packaging machine 14 can be ensured.

The new roller 12 of the second mounting position EB2 of FIG. 5 may preferably have an optically detectable adhesive mark 76, which may be formed in particular by a reflective or inductive or otherwise detectable adhesive mark 76, which on the outer layer 24 of the new roll 12 in the area free end is applied. The second mounting position EB2 associated camera 74 is now able to check by means of the adhesive mark 76, whether the new roll 12 with the appropriate direction of rotation or with direction of rotation conforming orientation on the

Take-up mandrel 70 has been postponed. A synopsis of Figures 5 and 6 can illustrate that with new role 12 of the second mounting position EB2 the externa ßere layer 24 is guided from above over the roller 12 and dives downwards. If the roller 12 with the wrong direction of rotation or incorrect direction of rotation conforming orientation placed on the arbor 70 of the second mounting position EB2, the externa ßere would Position 24 pointing away from the roll 12 in the direction downwards and would be difficult or impossible for this reason. In addition, this might possibly disrupt the rolling behavior within the packaging machine 14 or the course of the material web. An alignment below the welding bar 72 would thus not be possible. Positioning new rollers 12 in conformity with the direction of rotation or inserting new rollers 12 into the respective installation position EB1 or EB2 with a suitable direction of rotation is therefore essential in order to ensure trouble-free operation of the device 10 or the packaging machine 14 in the subsequent material conveyance of the material webs 22 can. If the adhesive marker 76 could be detected by means of the respective camera 74, then the receiving mandrel 70 is moved in rotation until the adhesive marker 76 points in the direction of the opposite installation position EB1 or EB2. Only after this alignment of the adhesive marking 76 can a merely shown in Fig. 6 schematically gripping bar 78 in the packaging machine 14 between the mounting positions EB1 and EB2 and the welding bar 72 movable gripping and / or handling device (not shown), the outer layer 24 of the new Role 12 grip and below the

Position the welding bar 72. This gripping bar 78 can, for example, by means of vacuum suction and grip the externa ßere layer 24 of the roller 12.

However, it should be noted that embodiments are also conceivable in which the new rollers 12 have no such reflective adhesive mark 76 (corresponding to FIG. 5) and in which the cameras 74 have an outer layer 24 of new rollers 12 or the free end regions of FIG recognize new roles 12 without additional visual markings of the new roles 12. Preferably, however, the optically detectable adhesive markings 76 have a coding, which is not explained here in further detail, which can be recognized by the cameras 74. These

Coding may preferably in addition to the localization of the end portion of the externa ßeren layer 24 and the direction of rotation of the roll 12 clearly identify, so that the

Adhesive marking 76 already in the handling of the new roll 12 to be used with the handling robot 18 to determine the direction of rotation and the right one

Positioning of the end region of the outer layer 24 can be used, if necessary with the additional inclusion of the clipboard 60. In this case, the adhesive marking 76 can preferably be detected by the room monitoring devices 42 or the camera 44 and the information content evaluated and made available to the control unit 38. to control the handling robot 18 and / or the clipboard 60 in the required manner. The installation positions EB1 and EB2 of FIGS. 4 and 5 with the outer layer 24 removed from the new roller 12 inserted into the second installation position EB2 show the schematic perspective view of FIG. 6. It can once again be clearly seen that the outer layer 24 of FIG In the second installation position EB2 positioned roller 12 coming from above descends in the downward direction, while the outer layer or material web 22 of the roll used in the first installation position EB1 20 is coming from below. Both rollers 12 and 20 rotate on their respective associated mandrels 70 with the same direction of rotation, here counterclockwise. A direction of rotation compliant insertion of the new rollers 12 is necessary to a trouble-free and functioning operation of the device 10 and

Packaging machine 14 (see Figures 1 and 2) to be able to guarantee.

Thus, both the possibility of detecting a direction of rotation or rotational direction-conforming orientation within the packaging machine 14 via the cameras 74 and of recognizing rollers 20 which are at least approximately completely unwound and / or applied via the cameras 74 are possible. Information about

Direction of rotation or direction of rotation conforming orientation of new roles 12 and

Information about at least approximately completely processed and / or used up rollers 20 are passed from the cameras 74 to the control unit 38, which can specify an alignment correction of new rollers 12 and a replacement of at least approximately unwound and / or used up rollers 20 by new rollers 12. This can in particular be done in a manner as already described with reference to FIGS. 2 and 3 with the optional inclusion of the

Direction of rotation correction usable clipboard 60 has been explained. In order to determine the correct direction of rotation, it makes sense, however, primarily to use the camera 44 and only subordinated to the cameras 74, to then check again after inserting the roller 12 in the packaging machine 14, the correct direction of rotation.

The schematic representations of FIGS. 7A and 7B show a part of the handling robot 18 which forms the gripping and / or handling device 16 for handling the rollers 12 in the device 10. The gripper arm or the

Arm portion 34 of the handling robot 18 is pivotable about the horizontally oriented axis 36, so that the retaining mandrel 32 of the handling robot 18 can be aligned for immersion in the core 26 of the respective new roll 12 with vertical orientation of its longitudinal axis. Was the respective new role 12 by means of

Handling robot 18 and detected by means of the retaining mandrel 32, the new roller 12 can be rotated by a new pivotal movement of the gripping arm 34 about the axis 36 and in time to their respective assigned installation position EB1 or EB2 (see.

FIGS. 4 to 6).

In addition, Figures 7A and 7B show an optional additional camera 80. This optional camera 80 is fixedly coupled to the gripping arm 34 mechanically so that it is guided with the gripper arm 34 moving therewith. If the gripper arm 34 is pivoted about the axis 36, so by means of the camera 80 a

Direction of rotation or direction of rotation compliant orientation of one or more new roles 12 are determined. In order to enable a corresponding evaluation and motion control for the gripping and / or handling device 16, the camera 80 is connected to the control unit 38, which receives a new roll 12, which has a suitable direction of rotation or rotational direction-conforming orientation, by means of the handling device 16 controls from the pallet 52.

Furthermore, Fig. 7B shows the gripping and / or handling device 16 after receiving a new roll 12 with direction of rotation-conforming orientation of a pallet 52 (see Fig. 7A). As can be seen in FIG. 7B, the gripper arm 34 was moved from the position of FIG. 7A about the axis 36, which in FIG

Image plane runs, pivoted. The new role 12 now has at least one

approximately horizontal orientation and can be assigned to their respective

Installation position EB1 and EB2 are used in the packaging machine 14. A removal of the at least approximately completed and / or

used-up roller 20 from the respective installation position EB1 or EB2 also takes place with a horizontal orientation. To remove the at least approximately completely unwound and / or depleted roll 20 from their respective installation position EB1 or EB2 dives the holding mandrel 32 of the handling robot 32 in the core 26 of at least approximately completely unwound and / or depleted role 20, resulting in different tools can be supported, which are explained below with reference to Figures 9 and 10 in more detail. By enlargement of the

Cross-sectional diameter of the retaining mandrel 32, the respective at least

Approximately completely unwound and / or used up roller 20 fixed to the retaining mandrel 32 of the handling robot 18. An enlargement of the

Cross-sectional diameter of the retaining mandrel 32 is specified via the control unit 38.

The schematic perspective view of FIG. 7C illustrates the process of depositing a holding mandrel 32 of the extension arm 34 of the handling robot 18 held new roll 12 on the rotatable and drivable rollers 94, which form the trough-shaped upper support surface 62 of the bearing block 64 of the clipboard 60. The roll 12 is deposited by means of the handling robot 18 on the clipboard 60, after which the retaining mandrel 32 is pulled out of the roll core 26 at the end of the gripping arm 34, the roll 12 is rotated in the desired manner by means of the rollers 94 and / or by means of the deliverable clamping jaws 68 in the axial direction Direction on the

Support surface 62 can be positioned in order to then resume them in the appropriate direction of rotation with the retaining mandrel 32 to use them finally in the packaging machine 14. The clipboard is also in this embodiment of FIG. 7C in turn equipped with a closed housing 100 for receiving and supporting the rollers 94 and the adjustable jaws 68 together with their ZuStellantrieb and / or feed mechanism 98 (see, see Figures 3F and 3G).

The two schematic perspective views of Figures 8A and 8B

illustrate the positioning process of a new roll 12 in one of the intended installation positions EB1 or EB2 in the packaging machine 14 (see Figures 4 to 6). Thus, Fig. 8A already shows a short distance to one

Take-up mandrel 70 in the packaging machine 14 new role 12 with

Packaging material previously separated from the retaining mandrel 32 of the handling robot 18. The retaining pin 32 was then provided with a stamping attachment 82, which was temporarily fixed to the retaining mandrel 32 of the handling robot 18 for the purpose of pushing the roller 12 onto the receiving mandrel 70 against an axial stop 84. This pushing operation, with which the stamp attachment 82 presses against the end face of the roller 12 until it is pushed against the axial stop 84 and thus into its intended installation position EB1 or EB2, is illustrated in FIG. 8B. After this

Reaching the installation position EB1 or EB2, the handling robot 18 can be released again from the roller 12 and fed to new tasks.

The lowering of a spent or almost used up roll 20 from the take-up mandrel 70 and the takeover by the holding mandrel 32 of the handling robot 18, on the other hand, is facilitated by means of a displaceable axial stop 84 and by means of a displaceable mounting of the rotatable take-up mandrel 70, as illustrated in FIGS. 9A to 9D.

The two schematic perspective views of Figures 9A and 9B

illustrate the different operating states of one in the intended Installation position EB1 or EB2 in the packaging machine 14 (see Figures 4 to 6) on the take-up mandrel 70 located roller 12 (Fig. 9A) and a remote therefrom (Fig. 9B). While the roll 12 in the illustration of FIG. 9A is ready to roll off in the intended installation position EB1 or EB2, it was pushed down from the take-up mandrel 70 in the illustration of FIG. 9B by displacing the axial stop 84 and, for example, from the handling robot 18 taken over (not shown). The displaceable axial stop 84 is located on a parallel to the

Longitudinal direction of the receiving mandrel 70 movable base 86 which is held in two parallel longitudinal guides 88 and movable. When located on the mandrel 70 roller 12 is held in the longitudinal guides 88 and horizontally displaceable base 86 with the axial stop 84 naturally close to a base 90 (FIG. 9A), the storage and a drive 92 for the rotationally driven Receiving mandrel 70 forms.

As the two schematic side views of FIGS. 9C and 9D illustrate, the entire pedestal 90, together with its drive 92 and the rotatably driven receiving mandrel 70, can also be designed to be displaceable along the two parallel horizontal guides 88, which is particularly advantageous for the equipping of the

Take up mandrel 70 with a new roll 12 and the removal of a used roll by the handling robot can facilitate. FIG. 9C shows a roller 12 positioned on the mandrel 70

Socket 90 with the drive 92 is in this case at a right stop, in which the roll 12 is ready for unwinding in the packaging machine 14. The axial stop 84 has moved with its base 86 against the base 90, so that it is in no touching contact with the roller 12. 9D also shows the roll 12 positioned on the mandrel 70. The base 90 with the drive 92 is displaced to the left here, as is the axial stop 84, which abuts with its base 86 on the base 90 and thus likewise moved to the left is. The rotatably mounted on the base 70 receiving arbor 70 together with the roller 12 thereon is here moved out of the installation position EB1 or EB2 a piece, so that the roller 12 is in any position that is suitable for unwinding, but in a sampling or placement position at which it can be easily taken over by the handling robot 18 or transferred to the packaging machine 14. In particular, the position shown in FIG. 9D may form the home position for pushing down the roller 12 from the mandrel 70 when the pedestal 90 with the mandrel 70 is moved to the right to the original operative position (corresponding to FIG. 9C) while the base 86 with the axial stop 84 in place (corresponding to Fig. 9D) remains. The mandrel 70 moves out of the roller core 26, while the axial stop 84 bears against the end face of the roller 12 and holds it in place. As a result, the retaining mandrel 32 of the handling robot 18 can be pushed into the released core 26 and the roll 12 finally take over from the mandrel 70 and pull off.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.
