Description

 Packaging machines and processes for the supply, provision and replacement of rolls

 Packing material

The present invention relates to a packaging machine for packaging at least partially enveloping products such as piece goods, containers or the like article compositions with withdrawn from rolls flat and / or sheet material having the features of independent claim 1. The invention also relates to a method for conveying, providing and / or handling and / or replacement of rolls having flat and / or sheet material wound thereon and having the characteristics of the independent one as packaging material for packaging piece goods, containers or similar article compositions

Process claim 6.

In a grouping and compilation of articles to containers, eg. Of beverage containers o. The like., These are often held together in practice by shrink film to prevent slipping or loosening of the compilation during further handling or 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 carried out by machine and in a continuous process. There are

 Devices are known in which the packaging material is withdrawn via rollers from the rotating roll. Is a roll settled and stock up

Packaging material of the role is exhausted, so must be an exchange of the respective role or a replacement by a new role. 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 articulated arm transfers bobbins 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. In such packaging machines are at irregular intervals

To carry out product changes in which the dimensions of the packaged goods may vary, so that the unwinding from the rolls and serving as packaging material flat or foil material can no longer be used, but against a flat or sheet material of different width, different strength and / or with other printing. It makes sense to do this by replacing one of the rolls with packaging material, but this is associated with several disadvantages. On the one hand, this role swap usually has to be done manually

be carried out when the respective product change is pending. In addition, the rolls removed from the packaging machine are usually not yet used up, so that a product change is not only accompanied by a slowing down of the packaging process, but can also be associated with a considerable waste of material.

For this reason, an object of the present invention is seen in a packaging machine and a method with a high degree of automation in the handling of rolled on flat and / or sheet material for

To make available. The available flat and / or sheet material should be largely utilized and waste avoided. This object of the invention is achieved with the objects of the independent

Claims reached. Features of advantageous developments of the invention will become apparent from the dependent claims. In order to achieve that objective, the

Invention a packaging machine for packaging at least partially to be wrapped products such as general cargo, containers or the like

 Article compositions with withdrawn from rolls flat and / or sheet material before. The packaging machine has at least one installation position and, in preferred embodiments, at least two different installation positions for the rollers. In the installation positions flat and / or sheet material can be unwound and provided for packaging the at least partially to be wrapped products. In addition, the packaging machine is provided with means for removal of

used and / or partially used roles from the respective or at least one installation position and / or for the insertion of new roles for replacement against used or partially used roles in the least one or in the respective installation position equipped. In addition, the packaging machine is associated with at least one temporary storage station for temporary storage of partially used rolls and their provision for reuse in the packaging machine. The intermediate storage station can thus be located within a working area of the device for the removal of used and / or partially spent rolls from the respective or at least one installation position. With the help of this the

Packing machine associated intermediate storage station can not be used up, but due to a product change temporarily no longer usable rolls of packaging material removed from operation, but kept ready for reuse at a later date. These

Intermediate storage station is suitable for fully automated operation, so that no manual intervention or roll change are required. The flat or

Film material can thus be adapted in each case to the products to be packaged or piece goods without unused rolls disposed of with packaging material and thus large amounts of packaging material must be wasted. The packaging machine is preferably a welding station for connecting a material web of a roll newly inserted into the respective installation position with a material web located in the packaging machine and a buffer for receiving a part of a taken during the welding process

Material web section associated with the role to be taken. The cache for the not suitable for the new products and therefore no longer needed Material web portion can accommodate parts of the material web, which still come from the removed role, and due to the for connecting the

Material web sections of the new roll with the material web still in the machine must be removed from the packaging process. This buffer can be arranged, for example spatially in an area above the at least two mounting positions. However, the buffer can also be spatially within the packaging machine in an area in the vicinity of a film wrapping module or on the way before the installation position for

Film wrapping module be arranged. The invention provides that at least a part of the conveyed back

 Material web section is conveyed to the cache and stored there. This temporary storage device can be emptied cyclically, for example, whereby the cyclical removal or emptying can take place, for example, by means of a handling device such as a robot or the like. Normally, preparing for a

Product change the web withdrawn during or before a separation process against the conveying direction for packaging and / or transported into the buffer. After retraction and / or separation of the web from the roll to be removed then a new web of the new

used roller are retightened in the conveying direction. A further advantageous embodiment of the invention

 Packaging machine can provide that this is a data storage for the detection, storage and availability of relevant data on the consumption state and / or the remaining length of the web still on the roll one of the

Packing machine removed and for re-insertion

cached role is assigned. With the aid of such a data memory, it is possible to associate stored relevant data with the roll taken out of the machine and placed in intermediate storage in order to have this data immediately available for the further packaging process if the previously removed roll can be used again in the event of a new product change. Furthermore, it is advantageous if the packaging machine a gripping and / or

Handling device, in particular at least one placed on the packaging machine handling robot for removing the partially used and

intermediately stored rollers from the at least one installation position, for Re-inserting these intermediate rollers and / or for the insertion of new roles in the at least one mounting position of the packaging machine is assigned, as a fully automatic operation is much easier.

The handling device or the multi-axis robot has suitable gripping and / or holding means, which may be formed by a holding mandrel, for example, which dips the front side into the trained as a hollow body new roles, increases its maximum cross-sectional diameter or its cross-sectional area increases and hereby the respective new roller clamped to the

Fixed handling device or the multi-axis robot. Optionally, the gripping and / or handling device can be formed by a driverless and / or remote-controlled transport system (so-called FTS with at least one self-propelled shuttle), which picks up new rolls from the defined feed and places them in the packaging machine.

In order to achieve the above-mentioned object, the invention further proposes a method for conveying, providing and / or handling and / or replacing reels with products wound thereon and as packaging material for packaging at least partially enveloping products such as piece goods, containers or similar article compositions serving flat and / or sheet material, wherein in a product change in a packaging machine partially unwound and / or used up role of at least one

Installation position is removed within the packaging machine and stored for further and / or reuse, while adapted to the new product new roll with flat and / or foil material is inserted into the respective at least one mounting position and welded to a material web located in the packaging machine , The method provides that at least a partial section of the material web located in the packaging machine is pulled back against the conveying direction for the packaging and removed from the conveying region of the packaging machine. In addition, a preferred option of the method provides that at least a part of the conveyed-back material web section is conveyed into a buffer store and stored there. This buffer can preferably be emptied cyclically or as needed, wherein the cyclic or as needed removal by means of suitable handling devices such as robots o. The like. Can be done. In particular, the buffer may be arranged spatially in an area above the at least one installation position, whereby he in the immediate vicinity of at least one installation position for the roles with

Packing material arranged and optimally placed for receiving short material web sections that are no longer needed in a product change.

To prepare for a product change, the material web, which is no longer suitable for the new product or does not optimally match the new product, may be contrary to the normal conveying direction before being separated, as is the case for packaging

is provided, withdrawn and / or transported to the cache. After retracting and / or separating the material web from the roll to be removed, a defined length of the new material web can then be drawn from the newly inserted roll in the conveying direction so that the packaging process of the new products is continued with the respectively provided flat or film material can.

In a variant of the method according to the invention, the rolls, which are only partially consumed and removed from the packaging machine, are stored temporarily and / or kept ready for renewed insertion into the packaging machine. This variant allows for temporary storage and reuse of the rolls at a later time by delivering them to a clipboard location, where they can be taken up again at any later time and inserted into the packaging machine. In addition, it may be advantageous if relevant data taken from the packaging machine and for a new insertion

cached roles are recorded, in particular data for

Consumption state and / or the remaining length of the still on the role

Web. These relevant data of the rolls can be used to advantage in order to make them available to the packaging machine after the reinsertion of the roll, so that an exact time of a necessary exchange for a new roll can be determined.

A reel change usually takes place in such a way that after each insertion of a new roll, an outer layer of this new roll is drawn off near or in the region of its free end and to form a continuous material web with a section of a web guided in the packaging web of another roll connected, in particular welded or glued. Since the new roll must be connected to a packaging material section already in the machine during a product change that is to be prepared with new piece goods dimensions and / or modified printings of the packaging material, this is part of the Machine located packaging material, however, is not suitable for further use, this relatively short section must be disposed of, in particular

cached and, if necessary, at a later date from the

Packaging machine can be removed. New roles become the

Packaging machine normally in defined feed, e.g. by means of pallets, shelving systems, AGVs (i.e., driverless transport systems) or the like, and inserted there by means of at least one gripping and / or handling device into the respective installation position, after previously having taken out a used or partly used and later reusable roll. The rollers are preferably picked up independently of the orderly feed by means of handling and gripping devices and inserted into the packaging machine.

The aforementioned gripping and / or handling device can be formed, for example, by a multi-axis robot, which picks up new rolls from the defined feed and places them in the packaging machine. In addition, the handling device or the multi-axis robot can have a holding mandrel, which dips into the front side in the form of a hollow body respective new roles, its maximum

Enlarged cross-sectional diameter and hereby fixed the respective new role by clamping the handling device or the multi-axis robot. Optionally, in the method according to the invention, the gripping and / or handling device can also be formed by a driverless and / or remote-controlled transport system (FTS, at least one self-propelled shuttle) which picks up new rolls from the defined feed and places them in the packaging machine. This FTS or the shuttle of the AGV may, for example, have a gripper arm or the like for receiving and handling the rollers, with which it picks up the roller, places it on a transport support, after which it travels together with the roller to the packaging machine and uses the roller there ,

New rollers can be moved, for example, via a horizontal conveyor into the area of the handling device and removed directly from the horizontal conveyor by means of the handling device. Also possible is a

Delivery of new rolls on pallets, so that, for example, four standing rolls are arranged on a pallet, which by means of a suitable delivery in the

Movement of the gripping and / or handling device are brought to be picked up by this and used in the packaging machine, possibly including the clipboard, as described above as an option. In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail.

Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments merely represent examples of how the packaging machine according to the invention and the method according to the invention can be designed and do not represent a conclusive limitation.

The schematic perspective view of Fig. 1 shows a variant of an inventive device 10 for handling rollers 12 in their

Insertion and / or removal from a packaging machine 14. 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, a part of the packaging machine 14, which are supplied via a new to be described in more detail below gripping and / or handling device 16 12 new rollers. In addition, the gripping and / or

Handling device 16 for the removal of used or partially used rolls 20 from the packaging machine 14. The trained in the embodiment shown as a stationary arranged multi-axis robot 18 gripping and / or

Handling device 16 sets each of the packaging machine 14th

to be supplied new rollers 12 in two different mounting positions EB1 and EB2, which are only partially recognizable in Fig. 1 and are exemplified in the detail view of FIG. 2.

As a synopsis of Figures 2 to 4 with Fig. 1, are by means of the gripping and / or handling device 16 or with the help of Mehrachs- or

Handling robot 18 single new roles 12 used in one of the two installation positions EB1 and EB2, while in the other installation position EB2 or EB1 is still a spent or partially used role 20, of which still during the insertion of each new roll 12 continues a On it located web 22 is unwound, in the packaging machine 14 as

Packaging material is processed. During the further Abwickeins the

Material web 22 of the almost applied or even partially used-up roll 20 takes place a connection or Verschwei ßung the outer layer 24 (see Fig .. 4) of the new roll 12 with the web 22, whereby the device 10 can run in a continuous operation without the packaging process for

Replacing an applied roll 20 with a new roll 12 would have to be interrupted. 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 of the pallets 52 indicated in FIG. 1, or alternatively from one not shown

Horizontal conveyor dips the handling device 16 and the

Handling robot 18 on one end on its movable arm 30 movably arranged holding mandrel 32 frontally into a core 26 of a new roll 12 a. An arm portion 34 of the handling device 16 or of the handling robot 18 can for this purpose be moved in rotation about a rotation axis. After immersing the retaining mandrel 32 in the core 26, the cross-sectional diameter of the retaining mandrel 32nd increases, so that the new roller 12 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 is for clamping fixing the new roller 12 via its outer periphery with an inner circumferential surface of the core 26 in conjunction. By means of the pallets 52 supplied regularly to the vicinity of the gripping and / or handling device 16 or the handling robot 18, new rolls 12 can be made available in an uninterrupted sequence. Optionally, the pallets 52 can be delivered in coordination with the signals of a 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, at least the

 Motion space of the multi-axis robot 18 and detect its movements, which also means the exact movements of the boom 30 with the pivotally mounted thereto retaining mandrel 32 with respect to each to be detected new role 12.

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

Work area 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 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. On each of the pallets 52 shown are each four vertically arranged

Rollers 12, which are each picked up individually by the handling robot 18 and inserted into the packaging machine 14. To accommodate a new roll 12 of one of the range within, ie within the range of movement of the gripping and / or handling device 16 and the multi-axis robot 18 standing pallets 52 dives the handling device 16 and the handling robot 18 via the end of his movable boom 30 movable arranged holding mandrel 32 frontally into a core 26 of a new roll 12 a. About the regularly supplied in the exercise room pallets 52, each with four new rollers 12 of the gripping and / or handling device 16 and the handling robot 18 new roles 12 in continuous sequence provided so that upon removal of all new rolls 12 of one of the pallets 52, this empty pallet 52 can be exchanged for a new pallet 52 with another four rolls 12, which in turn move into the movement space of the gripping and / or handling device place is. 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 room. These transport systems or FTS can be operated clocked as desired in the desired manner.

In order to keep different packaging materials available in the case of a product change required in the packaging machine 14, it is also possible to remove rollers 21 that are not completely exhausted but also only partially used up. In order to keep these partly unwound rolls 21 available for later use in the packaging machine 14 in the event of a new product change, in the variant of the device 10 shown in FIG. 1, the movement device of the gripping and handling device 16 and in its

a clipboard 60 is provided for the partially unwound rolls 21, which serves essentially to remove the removed rolls 21 not to be mixed with the new rolls 12, but which are still usable, for their reuse within the reach of the gripping and / or or

Handling device 16 to keep available.

In this connection, it is advantageous if relevant data of the rolls 21 removed from the packaging machine 14 and deposited on the clipboard 60 for renewed insertion are recorded, in particular data on the consumption state and / or the remaining length of the material web still on the respective roll 21 22. These relevant data of the rollers 21 can be advantageously used to make them available to the packaging machine 14 after the reinsertion of the roller 21, so that an exact time of a necessary

Exchange for a new roll 12 can be determined

The standing in Fig. 1 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. The schematic perspective view of Fig. 2 illustrates the previously mentioned mounting positions EB1 and EB2 for the rollers 12, which in the

Packaging machine 14 are defined according to the variant according to FIG. 1. Each of the mounting positions EB1 and EB2 is defined by its own rotatable

Take-up mandrel 70. A new roll 12 is attached to each of these two horizontally oriented receiving mandrels 70 by means of the gripping and / or handling device (see Fig. 1) and by enlarging the diameter of the receiving mandrels 70 by clamping the roll core 26 to the respective receiving mandrel 70 clamped fixed. 2 also shows a welding bar 72, which is used to connect an outer layer 24 (see FIGS. 3, 4) of the new roll 12 (see FIG. 3) inserted into the respective installation position EB1 or EB2 the remaining in the packaging machine 14 material web 22 is provided and this is lowered vertically. After joining the outer layer 24 (see Fig. 3) 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. 2, 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 installed position EB2, a worn-out roll 20 has already been completely unwound and the core 26 (see Fig. 1) removed via the handling device 16, so that the second installation position EB2 or the receiving mandrel 70 of the second installation position EB2 for receiving a new roll 12 with packaging material ready. Each of the installation positions EB1 and EB2 can be associated with a separate sensor system or camera 74, by means of which at least approximately completely unwound and / or used up rollers 20 as well as partially unwound rollers 21 (cf., FIG. If a roll 20 is at least approximately completely unwound and / or used up or if a product change is due and therefore a partially unwound roll 21 is to be removed, the respective camera 74 sends information about the respective at least partially completed and / or used up rolls 20 and 21 respectively to one

Control unit 38. On the basis of numerous data, including the cameras 74 within the packaging machine 14, this control unit 38 controls the gripping and / or handling device 18 or the handling robot 18 (see FIG Removal of the respective at least partially unwound and / or applied roll 20, 21 or for removal of the core 26 of the respective roll 20 and 21, respectively. So that the roller 20 or 21 can be removed from their respective installation position EB1 or EB2, a previously between the respective roller 20, 21 and the

Receiving mandrel 70 trained clamped connection solved. this happens

typically by reducing the cross-sectional diameter of the respective

Take-up mandrel 70, which can be the roll core 26 pull off. 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 partially completed and / or used up

Roller 20 or 21 from their respective installation position EB1 or EB2 dips the gripping and / or handling device 16 via its retaining mandrel 32 into the core 26 of the roller 20 or 21 to be removed. By enlarging the cross-sectional diameter of the receiving mandrel 70, the respective roller 20, 21 is then fixed to the holding mandrel 32 of the handling device 16. An enlargement of the cross-sectional diameter of the retaining mandrel 32 for clamping the roller 20 or 21 or of the roller core 26 is likewise predetermined via the control unit 38. After fixing the roller 20 or 21 on the retaining mandrel 32, the roller 20 or 21 by means of gripping and / or

Handling device 16 and under specification by the control unit 38 in the direction of the container 56 or the clipboard 60 (see Fig. 1) moves and stored there by reducing the cross-sectional diameter of the retaining mandrel 32.

After the removed roll 20 or the core 26 in the container 56 or the partially unwound roll 21 on the clipboard 60, the gripping and / or handling device 16 via the control unit 38 for inserting a new roll 12 in the respective installation position EB1 or EB2 within the

 Packaging machine 14 driven. The device 10 can be operated in this way together with the packaging machine 14 automated.

The further schematic perspective view of Fig. 3 shows the

Installation positions EB1 and EB2 corresponding to FIG. 2 with inserted new roller 12 for the second mounting position EB2. 2, a new roller 12 has been pushed onto the receiving mandrel 70 of the second installation position EB2 in the representation of FIG. 3 by means of the gripping and / or handling device 16 (see FIG. Furthermore, packaging material 22 or shrink film of the almost used or unwound and therefore soon to be removed role 20 of the first mounting position EB1 unwound, so that the packaging machine 14 (see Fig. 1) 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 inserted into the first installation position EB1, then it is still possible

Packaging material 22 or shrink film are unwound from the roll 12 of the second mounting position EB2, whereby the required continuous and uninterrupted operation of the packaging machine 14 can be ensured.

The installation positions EB1 and EB2 of Figures 2 and 3 with deducted externa ßer layer 24 of the inserted into the second mounting position EB2 new roller 12 shows the schematic perspective view of Fig. 4. For putting in there is a not completely unwound roller 21 in the first mounting position EB1 to be recognized, which is removed because of a product change from the packaging machine 14 and replaced by a new roll 12. Both rollers 12 and 21 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

To ensure packaging machine 14.

Fig. 4 also indicates a buffer 76, which is required for receiving a web portion 78, which comes after a product change from the to be taken, not yet needed, but not yet unwound roll 21, but not for the new product to be packaged suitable is. In this latch 76, which can be arranged in particular in the packaging machine 14 above the mounting positions EB1 and EB2, these can be shorter

Rail sections 78 are transported to be able to dispose of them later. To prepare for a product change, the material web 22, which is no longer suitable for the new product or does not optimally fit the new product, may be withdrawn and / or transported into the intermediate storage 76 before a separation process contrary to the normal conveying direction as provided for packaging become. After retracting and / or separating the material web 78 from the to

Removing roller 21 can then be followed by a defined length of the new material web 22 of the newly used roll 12 in the conveying direction, so that the packaging process of the new products can be continued with the respective intended flat or sheet material. Finally, the schematic view of FIG. 5 is intended to illustrate exemplary positioning of the buffer 76 for the film residues to be removed. For example, as already mentioned, the buffer 76 can be arranged spatially in an area above the at least two installation positions EB1 and EB2 (see FIG. 4). However, the latch 76 can according to FIG. 5 within the

 Packaging machine 14 also spatially in an area near a

Film wrapping module 80 or on the way before the installation position for
