The present invention relates to an apparatus and a method for providing roll-wound packaging material for articles such as beverage containers or the like.

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 of individual process steps is desirable.

In order to provide the packaging material or the shrink film for the partial or complete wrapping of containers, devices and methods are already known, which unwind the material from a roll or multiple roles, convey within a packaging machine and thus the individual container or the respective articles, which are to form the respective container, wrap with the packaging material. The unwinding of the packaging material from the roll is usually carried out by machine. Devices are known in which the packaging material is withdrawn via rollers from the rotating roll. If a roll is unwound and the stock of packaging material of the roll is exhausted, an exchange of the respective roll or a replacement by a new roll must take place.

A method and a device by means of which new rolls delivered and used rolls can be changed within a packaging machine are, for example, from the DE 40 40 545 A1 known. 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.

Devices for automatically feeding material wound on rolls and exchanging for used rolls in processing or packaging machines are also known in different embodiments, so for example by means for feeding and changing coils with strip material in a processing machine according to DE 32 02 647 A1 , according to DE 41 42 256 A1 , according to DE 101 09 446 A1 or according to DE 693 25 069 T2 ,

The DE 34 25 734 A1 discloses an automated system for feeding 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 consumables or packaging material is also from the EP 1 273 541 B1 known. The wound as reels of material webs are delivered to pallets and distributed to several manufacturing and packaging machines, the pallets are first transported by pallet conveyor in temporary storage, while individual reels are removed by separate reel bobbin and transported to a machine to be supplied.

The 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 winding units arranged outside the portal. 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 the devices known from the prior art, problems may arise in practice in particular when it is desired or intended to set up rolls for unwinding their material automatically on a working mandrel of a packaging machine.

It is conceivable here that the specific relative position is selected and / or predetermined taking into account a longitudinal extension of a roll to be placed on the working mandrel from a plurality of relative positions. The stop may have an opening or a receptacle for the retaining pin, through which the retaining pin is guided when placing the stop on the retaining pin. In particular, the stop can be placed with little play on the retaining pin. A cross section of the retaining pin can taper in the direction of its free end, whereby a placement of the stop on the retaining pin is facilitated.

It is also conceivable that the stop is fixed via at least one screw on the retaining pin in the specific relative position.

It is also conceivable that temporally after immersion of the retaining mandrel in the core of the roll at least one clamping element of the retaining mandrel widens the cross-sectional diameter of the retaining mandrel or the retaining mandrel in cross-section increases, resulting in the role kraftbeaufschlagt is fixed to the retaining mandrel and wherein the at least one clamping element in a recess of the stop dips. Also, several or at least two clamping elements may be provided, which is for expanding the Cross-sectional diameter move radially away in the direction of the retaining pin or which extend the cross-sectional diameter by a respective radial movement. The plurality or at least two clamping elements can in this case dip into a respective associated recess of the stop. As previously mentioned, the stop may have an opening through which the retaining pin is guided. The plurality or at least two recesses may be formed radially in the region of the opening in the stop.

Further, it may be that the stop comes into surface contact with its front side by approximately 360 ° along a winding course of the wound on the roll packaging material. Such embodiments have proven effective in minimizing the risk of damage to the packaging material wound on the roll upon contact with the stop.

In preferred embodiments, it may also be provided that the stop limits the immersion of the retaining mandrel into the core such that the retaining mandrel is immersed in the core by at most three quarters along the amount of the longitudinal extent of the core.

The invention also relates to a device for providing packaging material wound on rolls for articles such as beverage containers or the like. Features which have already been described above for various embodiments of the method can also be provided in various embodiments of the device according to the invention and are therefore not mentioned redundantly.

In preferred embodiments, the packaging machine may comprise two working mandrels, each adapted to receive a roll and unwind the packaging material wound on the respective roll. As a result, rolls can alternately be placed on the two working mandrels and unwound from the rolls of respective packaging material. Such embodiments have proven to be able to provide packaging material for articles without interruption via the packaging machine.

Furthermore, the device comprises a handling device with a retaining pin, which can dive for receiving a respective role in a core of the respective role and attach the role on the working mandrel.

In addition, the device comprises a control device, which is in communication with the handling device. The control device can be designed as a computer-aided system.

It is provided that the handling device comprises a stop for the end face of the respective roll to be received, which stop limits the immersion of the retaining pin in the core along its longitudinal extent. Accordingly, the stop can limit the immersion of the retaining mandrel into the core along its longitudinal extension such that a free space for attaching the core to the working mandrel remains in the core.

In preferred embodiments, the stop may be formed as a removable part of the handling device. It is conceivable here that the stop is fixed via at least one fixation removably attached to the handling device.

It is also conceivable that the stop in several different relative positions relative to the retaining mandrel on the handling device can be fixed, which are matched to different relative positions on roles with different lengths or longitudinal extents or with different amounts of their lengths or longitudinal extents. In particular, the different relative positions can be matched to the rollers with different lengths or longitudinal extent such that after immersion of the retaining mandrel in the core remains a free space in the core over which the respective role or the respective core can be plugged onto the working mandrel of the packaging machine.

It may also be that the stop is seated on the retaining mandrel and is displaceable in the specific relative position on the retaining mandrel. Possibly. In this way, the stop can be brought into the specific relative position provided for a respective roll with a defined longitudinal extension in a simple way.

Furthermore, the stop can be designed in terms of its geometry as a cylinder and in particular as a circular cylinder. A plane end face of the stop, which is designed as a cylinder and in particular as a circular cylinder with regard to its geometry, can be designed as a contact surface with which a front side of the role in their receipt device on the retaining pin in plant.

It may be advantageous for the recess to be coaxial with the stop in the stop formed in terms of its geometry as a cylinder and in particular as a circular cylinder. Optionally, however, the recess may also be introduced concentrically into the stop formed in terms of its geometry as a cylinder and in particular as a circular cylinder.

4 shows a schematic detail view of individual components of the handling device 1 with clarification of other aspects.

For the same or equivalent elements of the invention are in the 1 to 4 usually the same reference numerals used. 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 are merely examples of how the invention may be configured and are not an exhaustive limitation.

The schematic perspective view of 1 illustrates a first embodiment of a device according to the invention 10 for providing on rolls 12 wrapped thermoplastic packaging material. The device 10 includes a packaging machine 14 with two working mandrels, of which a working mandrel by reference with numeral 11 can be seen. The in 1 unrecognizable, however existing further working mandrel is by a in the packaging machine 14 arranged roll 12 covered. On each of the two working mandrels 11 was previously a role 12 by means of a multi-axis robot 18 trained handling device 16 placed. The handling device 16 can work on each of the working thorns 11 a role 12 Place with flat packaging material. Is a supply of packaging material one in the packaging machine 14 role 12 exhausted or at least approximately exhausted, so the handling device 16 the used roll or a core 26 the spent roll from the packaging machine 14 remove.

In the 1 shown device 10 gets the roles 12 each on pallets 52 Delivered, taking on each pallet 52 four upright rollers 12 stand, each individually from the handling device 16 taken and into the packaging machine 14 be used. To pick up a roll 12 from within reach, ie within a range of movement of the handling device 16 or the multi-axis robot 18 standing pallets 52 the handling device emerges 16 or the multi-axis robot 18 over the end of his movable boom 30 arranged retaining pin 32 inside a core 26 a role 12 one. The boom arm 30 and a working arm 34 the handling device 16 can be pivoted relative to each other. Previous is a position of the roll core 26 by means of one in the area of the retaining pin 32 at the handling device 16 attached camera system 41 (see. 4 ) detected.

To the respective role 12 specifically on the working mandrel 11 to be able to touch, before movement of the role 12 over the handling device 16 in the direction of the working mandrel 11 a Longitudinal extension of the roll 12 determined or determined. Since all of the in 1 illustrated roles 12 With respect to their geometry or dimensioning identical or approximately identical, it may be sufficient in practice, if the longitudinal extent of only one roll 12 is determined and determined for a sequential placement of all of the roles 12 on the working thorn 11 this determined longitudinal extent is taken into account.

Own the roles 12 different geometries or dimensions, can for the roles 12 each determined their longitudinal extent or determined with different geometries or dimensions. Also, for example, may be provided formed of plastic pattern, which with the rollers 12 in terms of their geometry and dimensioning and based on which pattern the longitudinal extent of the rollers 12 with the help of the handling device 16 is determined or determined.

The determination or determination of the respective length or longitudinal extension of the rollers 12 can be done, for example, by the rollers 12 from the handling device 16 or the multi-axis robot 18 be scanned. It is also conceivable that information on the longitudinal extent of the roles 12 a control device 38 are given, which taking into account the information, the handling device 16 to take on a respective role 12 and attaching the respective role 12 on the respective working mandrel 11 the packaging machine 14 controls.

As it is in the 2 to 4 can be seen, has the handling device 16 or the multi-axis robot 18 a stop 40 for a front side of a counter-role 12 , When dipping the retaining pin 32 in the core 26 a role to be taken 12 the stop occurs 40 , as in 2 to recognize, with a front side of the role 12 in surface contact. The presentation of the 3 can show that the attack 40 the immersion of the retaining pin 32 along the longitudinal extent of the core 26 limited. Thus, a free space remains at the core 26 which is for attaching the core 26 on the working thorn 11 the packaging machine 14 serves. The stop 40 therefore limits the immersion of the retaining pin 32 in the core 26 the packaging machine 14 such that the retaining pin 32 and the working thorn 11 when attaching the role 12 or the core 26 the role 12 on the working thorn 11 do not come into surface contact with each other (see. 3 ).

To the immersion of the retaining mandrel 32 along the longitudinal extent of the core 26 to limit, becomes the stop 40 before dipping the retaining pin 32 in the core 26 on the retaining pin 32 put on and then in a specific relative position relative to the retaining pin 32 pushed. The determined relative position is taking into account a longitudinal extent of a counter-taking and on the working mandrel 11 to be staked roll 12 selected. The particular relative position is in this case designed such that the retaining pin 32 at most three quarters along the amount of the longitudinal extent of the core 26 in the core 26 can dive. The stop 40 then enters with a front side of the roll 12 in surface contact. As 3 can show, in the remaining free space of the core 26 the working thorn 11 be plugged.

After setting the stop 40 in the specific relative position relative to the retaining pin 32 can the handling device 16 thus a respective role 12 with a movement adapted to the determined and / or determined longitudinal extension movement on the mandrel 11 the packaging machine 14 put on. This is the working arm 34 ( 1 ) of the handling device 16 or the multi-axis robot 18 for immersion in the roll core 26 moved in rotation about a rotation axis. After immersing the retaining pin 32 in the roll core 26 becomes the cross-sectional diameter or the cross-sectional area of the retaining pin 32 enlarged, so the role 12 on the retaining pin 32 is clamped fixed. The core 26 is formed hollow cylindrical, the shape of the retaining pin 32 Corresponding thereto, so that the retaining pin 32 for the clamping fixation of the roll 12 over its outer periphery with an inner circumferential surface of the core 26 communicates.

To the role 12 after acceptance of the retaining pin 32 on the working thorn 11 to be able to put on, is the boom 30 panned and the roll 12 along with the retaining pin 32 in the direction of the working mandrel 11 emotional. Next is the retaining pin 32 opposite the working mandrel 11 aligned and maintaining the alignment in the direction of the working mandrel 11 moved until the working thorn 11 in the role 12 or the core 26 the role 12 submerged in sections. Since still the retaining pin 32 in the role 12 or the core 26 the role 12 can, the role can 12 or the core 26 initially not completely on the working mandrel 11 be deferred. The determined longitudinal extent of the role 12 will when putting the role 12 on the working thorn 11 therefore considered, so that the retaining pin 32 not with the working thorn 11 comes into contact. The role 12 is therefore adapted to the determined or determined longitudinal extent movement on the working mandrel with a 11 the packaging machine 14 put on, so that still in the role 12 or in the roll core 26 dipped holding pin 32 the handling device 16 not with that working Dorn 11 collides or not with the working mandrel 11 comes into surface contact. The stop 40 limits immersion of the retaining pin 32 in the core 26 along its longitudinal extent.

After the role 12 on the working thorn 11 as described above, the retaining pin can 32 from the roll core 26 be pulled off or pulled out. Following this is the role 12 along the longitudinal extension of the working mandrel 11 pushed until the working thorn 11 completely through the roll core 26 passes. This can be done manually in particular. In preferred embodiments, the handling device slides 16 or the multi-axis robot 18 the role 12 along the longitudinal extent of the working mandrel 11 until the full penetration of the working mandrel 11 through the roll core 26 , To the sheet-like thermoplastic packaging material from the on the working mandrel 11 mounted roll 12 Unwrap, which is on the working mandrel 11 attached role 12 by increasing the cross-sectional diameter of the working mandrel 11 clamping or rotationally fixed on the working mandrel 11 set. Subsequently, the working mandrel 11 rotating, wherein sheet-like thermoplastic packaging material of the clamping on the working mandrel 11 fixed role 12 unwound and provided for the packaging of beverage containers.

About the regular in the movement space of the handling device 16 supplied pallets 52 each with four new roles 12 can the handling device 16 or the multi-axis robot 18 for a substantially uninterrupted packaging operation always new roles 12 be made available in an uninterrupted sequence so that when removing all roles 12 from one of the pallets 52 this empty palette 52 against a new palette 52 with another four roles 12 can be exchanged, in turn, in the movement space of the handling device 16 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 one pallet 52 with roles placed on it 12 in the movement space of the handling device 16 can carry.

These transport systems or FTS can be operated clocked as desired in the desired manner. Their operation is preferably predetermined by the control device 38 ,

Next is a shelf 60 for the roles 12 provided, which serves when on the pallets 52 normally undefined direction of rotation of the rollers 12 the indispensable direction of rotation positioning of each roller 12 when inserting into the packaging machine 14 or when placing on the working mandrel 11 to be able to guarantee. In practice, the retaining pin captures 32 the handling device 16 every single role 12 that on the pallet 52 stands without the direction of rotation being checked. By appropriate optical control or by detection in other ways (eg inductive, by means of transponder or similar) is during the movement of the cantilever arm 30 with the on the holding pin 32 promoted role 12 in the direction of the packaging machine 14 Check if the role 12 there can be positioned directly and without repositioning or whether the role 12 possibly has a wrong direction of rotation. If so, the role may be 12 by a corresponding movement control of the handling device 16 on the shelf 60 are dropped, after which the retaining pin 32 from the core 26 the discarded roll 12 is pulled out to the role 12 at their other end to capture again, in order then in each required direction of rotation on the working mandrel 11 the packaging machine 14 to be able to put on. The stop 40 in each case limits the immersion of the retaining pin 32 in the core 26 the role 12 along its longitudinal extent.

The in 1 within the movement space of the handling device 16 standing users 50 Usually there is only for maintenance purposes, but not during operation of the handling device 16 ,

Next is in 1 an open-topped container 56 recognizable, located in the working area of the handling device 16 located. Is the supply of packaging material or shrink film one in the packaging machine 14 placed roles 12 exhausted, by means of the multi-axis robot 18 the core made of cellulose, plastic, wood or cardboard 26 an empty role 12 from the packaging machine 14 taken and in the container 56 stored. Only after removal of the core 26 can a new role 12 on the respective working mandrel 11 the packaging machine 14 be placed so that the handling device 16 or the multi-axis robot 18 first the core 26 from the respective working mandrel 11 takes out and chronologically following a new role 12 on the respective working mandrel 11 touches down.

As already mentioned, stand the handling device 16 or the multi-axis robot 18 and the packaging machine 14 in connection with the control device 38 , which also optionally not shown here FTS for delivering the pallets 52 can control. The control device 38 Thus, in particular, it is possible to specify the timed operation of the AGVs, insertion and removal of roles 12 through the handling device 16 from respective working mandrel 11 initiate, and if necessary, the filing 60 to ensure the correct direction of rotation of a new roll to be used 12 to use.

The control device 38 can also have a display device 58 or have a display about the / the information on the operational role parameters, the direction of rotation or direction of rotation conforming orientation of 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.

With reference to 1 It should be added at this point that the handling device shown 16 or the forming this multi-axis robot 18 optionally in double or triple version may be present, provided that the movement spaces of the two or more multi-axis robot 18 are coordinated in a way that there can be no collisions. Each of these handling devices 16 or multi-axis robot 18 can make a stop 40 own, which is the immersion of the respective retaining mandrel 32 along the longitudinal extent of the core 26 the respective counteracting role 12 limited. Because of the web lengths on the rollers 12 However, normally a longer uninterrupted operation is guaranteed, the roles must 12 not so often replaced, that this requires the use of two or more multi-axis robots 18 would be necessary.

However, a useful embodiment variant can provide that a handling device 16 or a single multi-axis robot 18 two packaging lines or two packaging machines 14 can provide, with the movement space usefully between the two approximately parallel packing machines 14 is located, so that also the feed area for new roles 12 between the two packaging machines 14 and near the multi-axis robot 18 or his movement space is located. In this case, the handling device 16 mutually the two in regular operation packaging machines 14 each with roles 12 supply and the used roles if necessary into a common container 56 for subsequent or cyclical disposal.

The schematic detail view of 4 also shows individual components of the handling device 16 out 1 , where further aspects are clarified in more detail. Shown again is to accept a role 12 provided retaining pin 32 , which tapers towards its free end.

The retaining pin 12 includes several clamping elements 43 , in the 4 an approximately uninterrupted circular cross-section of the retaining mandrel 32 do not protrude in the radial direction. After the retaining pin 32 in the core 26 a role 12 was immersed, the clamping elements 43 to increase the cross-sectional diameter of the retaining mandrel 32 guided radially outward. The clamping elements 43 occur here with an inner circumferential surface of the core 26 in conditioning and put the core 26 or the role 12 Stressed on the retaining pin 32 firmly.

In addition, the clarifies 4 that the stop 40 for each of the clamping elements 43 a recess 42 possesses, in which the clamping elements 43 when increasing the cross-sectional diameter of the retaining pin 32 enter. Each of the recesses 42 extends completely along the entire parallel to the longitudinal axis of the retaining pin 32 oriented longitudinal extension of the stop 40 ,

Also is in 4 a camera system 41 to recognize which in the area of the holding mandrel 32 at the handling device 16 is positioned and thus on the handling device 16 or in connection with this can be moved or positioned. The control device 38 (see. 1 ) stands with the camera system 41 Can connect via the camera system 41 the respective position of a nucleus 26 one over the retaining pin 32 role to be taken 12 and thus the retaining thorn 32 in the core 26 a respective counteracting role 12 plunge.

The invention has been described with reference to the in the schematic representations of 1 to 4 illustrated preferred embodiment described. This, however, by no means precludes the person skilled in the art from making modifications or changes to the invention without thereby abandoning the scope of protection of the following claims.
