Description

The present invention relates to a method for conveying, providing and / or largely uninterrupted 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 assemblies within a packaging machine. The invention also relates to a packaging machine for packaging piece goods, containers or similar article compositions with flat and / or sheet material.

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 known, which unwind the material from a roll or from several roles, convey 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 respective roll is usually carried out by machine and in a continuous process. Devices are known in which the packaging material is withdrawn via rollers from the rotating roll.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. However, with such a roll change an undesirable interruption of the process of compilation and packaging of packages is connected.

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. 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 role with opposite direction of rotation placed on the pin, the strip material could not or only with difficulty be removed from the roll, resulting in complications in the settlement. 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 exchanging for used rolls in processing or packaging machines are also known in different embodiments, for example. By devices for feeding and changing coils with strip material in a processing machine according to DE 32 02 647 A1 or according to DE 41 42 256 A1 ,

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 spent by means of pallet conveyors in temporary storage, while individual reels are removed by separate Bobinenförderer 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 facility includes a Bobinenlager with a portal in which the bobbins 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.

From the DE 693 12 516 T2 In addition, there is disclosed an automatic scanning system with a robot used for exchanging rolls of wrapping material thereon. The robot has a controlled articulated arm with a gripping member for picking up objects such as rollers. The gripping member is equipped with an optical image acquisition device that supplies point matrices to a control unit, which calculates therefrom coordinates of the detected object or the role.

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 rolls is endangered, as a result of which the functionality of the packaging machine can no longer be guaranteed. In addition, the known systems for continuous operation require several film rolls, which can be changed between, while a respective used role is removed from the system and replaced by a new role.

On the other hand, the primary objects of the present invention are to provide a packaging machine and a method of operating it with a high degree of automation for handling flat and / or sheet material wound on reels, wherein only one installation position for a reel with wound thereon Flat and / or sheet material is available inside or outside the packaging machine. Nevertheless, even when using only such an installation position, a largely uninterrupted packaging operation should be made possible, largely dispensing with manual or manually supported roll changes.

These objects of the invention are achieved with the objects of the independent claims. Features of advantageous developments of the invention will become apparent from the dependent claims.

To achieve the stated objectives, the invention proposes, on the one hand, a method for conveying, providing and / or largely uninterrupted handling and / or replacement of rolls with flat and / or wound-up packaging materials used as packaging material for packaging piece goods, containers or similar article compositions Foil material with the features of the independent method claim. In the method, a defined length or a defined portion of the flat and / or sheet material of an approximately unwound and / or used up role before their exchange for maintaining an approximately continuous packaging operation in a buffer of a packaging machine promoted and temporarily stored there to be for the subsequent roll change to be available and to be able to maintain a continuous or quasi-continuous packaging operation even during the roll change. For this purpose, the mentioned portion of the flat and / or sheet material is conveyed into the buffer before the approximately unwound and / or used roll is removed from its installation position from the packaging machine or in the area or in the vicinity of the packaging machine and by a new roll is replaced with flat and / or foil material. During this reel change, the packaging operation can be maintained unchanged by removing the flat and / or foil material section located in the intermediate storage from there, while at the same time the flat and / or foil material of the reel inserted into the installation position in or in the area of the packaging machine connected from the buffer and continuously conveyed into the packaging machine flat and / or foil material portion connected, in particular transversely welded to its conveying direction. Through this connection or welding of the section located in the buffer with the beginning of the film of the newly used role of the desired continuous packaging operation is possible.

The supply rolls of flat and / or film material newly used or respectively made available to the packaging machine for replacement of respectively used up used rolls are respectively provided to the packaging machine in a defined feed and inserted into the installation position after the at least partly used roll has been removed there before , wherein the continuous packaging operation is maintained by at least partial consumption of the previously promoted in the buffer memory flat and / or sheet material. With the term of the defined feed different promotion variants can be meant. Thus, for example, the defined feeder may comprise a horizontal conveyor belt with new supply rolls conveyed thereon to the packaging machine, which are received, for example, by means of a gripping and / or handling device such as a multi-axis robot, and in the installed position can be brought. However, the defined feed can optionally also be formed by so-called FTS driverless transport systems, which bring each individual new supply roll with a remote-controlled self-propelled shuttle to the packaging machine and there with the help of an in-house handling gripper or with the help of available there gripping and /. or handling system or robots in the installed position in or on the packaging machine.

In a variant of the method according to the invention, the severing or separation of the flat and / or sheet material of the approximately unwound and / or spent roll from the continuously fed into the packaging machine flat and / or sheet material as well as the compound of the unwound from the newly used role Flat and / or sheet material with the continuously conveyed into the packaging machine flat and / or sheet material made largely automated. In this case, the individual, successive sequences are preferably centrally controlled, possibly supported by suitable image processing systems with which the gripping and / or handling devices can be controlled. In this way, both the removal of an approximately unwound and / or used up role from its installation position in the packaging machine as well as the insertion of a new role in this installation position can be largely automated. The removal of used rolls from the installation position and the insertion of new rolls in the installation position can preferably be carried out by means of at least one controllable gripping and / or handling device whose range covers a definable range of motion. This gripping and / or handling device can be formed, for example, by a multi-axis robot or by FTS or a combination of these elements.

In the method, it may be provided that the cutting through of the flat and / or sheet material and / or its welding by the gripping and / or handling device or by the appropriately equipped multi-axis robot is performed.

In order to achieve the above-mentioned objects, the invention further proposes a packaging machine for packaging piece goods, containers or similar article assemblies with flat and / or sheet material, which is provided with at least one device for feeding, providing and / or largely uninterrupted handling and / or replacement of rolls with packaging material wound thereon for packaging the piece goods, containers or article assemblies is equipped. The device is associated with at least one replaceable roll of packaging material which is in an operating condition in an installed position in or in the region of the packaging machine, wherein the installation position of the roll also a buffer for receiving a defined length of the flat and / or sheet material of approximately unwound and / or used up for reuse after insertion of a new roll is assigned to the installation position. This the installation position of the role functionally and preferably also spatially associated cache is used to maintain an approximately continuous packaging operation and can for this purpose, the mentioned defined length of the flat and / or sheet material of approximately unwound and / or used up role at least temporarily record this recorded Flat and / or sheet material during a replacement process of the used roll against a new role again, so that thereby the packaging operation can continue without interruption. To make this possible, the device for conveying, providing and / or largely uninterrupted handling and / or replacement of the rolls to maintain a continuous packaging operation in an exchange of roles by removing the intermediate storage in the flat and / or foil material section is prepared and set up. The at least temporarily located in the buffer length of flat and / or sheet material must be sufficient at least for a period of packaging operation, for the replacement of a used roll and the onset of a new supply roll and for the subsequent joining of the film or flat web sections, in particular for their Welding is needed.

The device for conveying, providing and / or largely uninterrupted handling and / or replacement of the rollers for maintaining the continuous packaging operation may preferably be equipped with a welding unit, the connection and welding of the flat and / or sheet material of a new in the installed position used in or in the field of packaging machine role with the removed from the buffer and continuously fed into the packaging machine flat and / or foil material section transverse to its conveying direction. Both the role change, the intended use of the buffer and the welding process can preferably be automated, so that even with only one role in the installation position of the packaging machine, a continuous packaging operation over a very long period can be maintained. At least the device for feeding, providing and / or for largely uninterrupted handling and / or replacement of the rolls can be operated automatically to maintain the continuous packaging operation.

The installation position for the rolls with flat and / or foil material wound thereon may optionally be inside the packaging machine or outside and immediately next to the packaging machine. In an installation position outside the packaging machine accessibility for removal of used rolls and for the insertion of new supply rolls is improved, while the flawless Flachbahn- or film guide may require more design effort.

The packaging machine according to the invention may be associated with at least one controllable gripping and / or handling device for removing used rolls from the installation position and for inserting new rolls into the installation position, the range of which covers a definable movement space. This controllable gripping and / or handling device can also be equipped with means for severing the flat and / or sheet material and / or its welding. As such gripping and / or handling device can be used in particular a multi-axis robot or a system of FTS, as has already been described above.

The movements of the gripping and / or handling devices or the handling robot and / or the driverless transport system (FTS) can usefully be detected and / or controlled by means of suitable optical sensor devices and / or room monitoring devices. Depending on the detected spatial, motion and / or sensor data, at least the movements of the gripping and / or handling device can thus be controlled in the area of the defined supply and / or provision for the rollers or in their respective movement space. In addition, it can be provided that the aforementioned room monitoring devices are formed by at least one optical detection device, in particular a camera, which detects at least the movement space of the gripping and / or handling device and images this movement space and the movements of the gripping and / or handling device taking place therein Output signals. Here, the at least one optical detection device or the camera, for example, the gripping and / or handling device assigned or mounted there, so that it is capable of the movements of the gripping and / or handling device and the direction of rotation compliant orientation of each new role before or during their insertion to check. Optionally, however, the camera can also cover the movement space by being fixedly mounted in the room or on the packaging machine; Additional or multiple cameras on the gripping and / or handling device are possible. In general, a plurality of cameras or optical detection devices can be used whose output signals are superimposed and can be used for exact location determination of all moving parts, handling systems and / or rolls of packaging material. The same applies to the removal of used rolls and for the use of welding equipment, which are necessary for connecting the material web sections; These elements can also be controlled by means of the optical detection devices.

In the method, the gripping and / or handling device can be formed, in particular, by a multi-axis robot which picks up new rolls from the defined feed and places them in the installed position and / or the packaging machine and also removes used rolls therefrom. As mentioned, the handling robot may optionally be associated with a separate camera, which may, for example, be mounted on its movable arm so that it can detect all movements in the room as well as the rollers to be positioned and positioned in the packaging machine. The handling device or the multi-axis robot preferably has suitable gripping or holding elements in order to be able to receive the rollers. Thus, the handling device or the multi-axis robot, for example, have a retaining mandrel which dips into the front side designed as a hollow body new role, increases its maximum cross-sectional diameter and thereby 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 , Optionally, the shuttle can be assigned its own camera to control its movements in the room.

The invention may further provide that the packaging machine itself or their Installation position for the interchangeable rolls with packaging material to be optically monitored. In this case, additional optical monitoring devices or cameras can be provided in the packaging machine, in particular in the region of the roles to be replaced or in the region of the installation position.

In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail. The proportions of the individual elements to one another in the figures do not always correspond to the actual size ratios, since some shapes are simplified and other shapes are shown enlarged in relation to other elements for better illustration.

1 shows in four schematic diagrams successive process steps in the automated replacement of rolls with packaging material wound thereon within a packaging machine.

2 shows in four schematic perspective views different handling steps when replacing the roles using a handling robot.

3 shows a schematic view of an installation position of a roll with wrapping thereon packaging material outside the packaging machine.

For identical or equivalent elements of the invention, identical reference numerals are 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 device or method of the invention may be configured and are not an exhaustive limitation.

The four schematic diagrams of the 1 should be several consecutive process steps in the automated replacement of roles 10 with wrapping material wrapped on it 12 within a packaging machine 14 clarify. The process steps shown are part of a method according to the invention for the delivery, provision and / or largely uninterrupted handling and / or replacement of rolls 10 with it wound up and as packaging material 12 for the packaging of piece goods, containers or the like article compositions serving flat and / or sheet material 16 that as packaging material 12 serves. The role 10 is in a defined installation position 18 inside or outside the packaging machine 14 (See also 3 ). The figure at the top left, shown as the first process step S1, shows a largely unused role 10 who are in their installation position 18 in the packaging machine 14 or in the area of the packaging machine 14 located. The role 10 is rotatably mounted about a horizontal axis, so that their packaging material 12 or the wound flat and / or sheet material 16 in the direction of the arrow in a packaging line 20 for packaging the general cargo, containers, article compilations, etc. can be promoted. One in close proximity to the installation position 18 located cache 22 for receiving a defined length of the packaging material 12 becomes in normal operation when unwinding the largely unused role 10 not needed yet.

The figure at the bottom left, shown as the second process step S2, shows one in the same installation position 18 and already almost completed role 24 , whose to the packaging line 20 promoted packaging material 12 through the cache 22 is directed where a defined length of the packaging material 12 or a defined section 26 of the flat and / or sheet material 16 the approximately unwound and / or used up roll 24 before being exchanged, it is conveyed to maintain an approximately continuous packaging operation where it is temporarily stored in order to be available for the subsequent roll change and to be able to maintain a continuous or quasi-continuous packaging operation even during the roll change. Like this the process step S2 of the 1 clarifies, becomes the mentioned section 26 of the flat and / or sheet material 16 in the cache 22 transported and folded there, for example, several times, before the almost unwound and / or used up role 24 in the next process step S3 (picture below right) from its installation position 18 from the packaging machine 14 or in the area or in the vicinity of the packaging machine 14 taken and by a new role 10 with flat and / or foil material 16 is replaced. During this roll change, the packaging operation can be maintained unchanged by the in the buffer 22 flat and / or foil material section 26 is removed from there, while at the same time the flat and / or sheet material 16 the new in the installation position in or in the field of packaging machine 14 used role 10 with the one from the cache 22 taken and continuously in the packaging line 20 subsidized flat and / or foil material section 16 connected, in particular transversely welded to its conveying direction (not shown).

The figure at the bottom right with the process step S3 illustrates the removal of the approximately worn role 24 After the rest of it wound on flat and / or sheet material 16 from that to the cache 22 promoted section 26 was separated. There is also the onset of a new role 10 in the installation position 18 clarified, then with the section 26 from the cache 22 while at the same time the packaging operation is maintained largely undisturbed by the section 26 without interruption in the packaging line 20 is encouraged. This one from the cache 22 promoted section 26 must then with the flat and / or foil material 16 the new role 10 connected, in particular welded, which is only indicated in the fourth process step S4 (right figure above). Through this connection or welding of the in the buffer 22 located section 26 with the beginning of the film of the newly used role 10 the desired continuous packaging operation is realized.

The replacement of each used up roles 24 newly used or the packaging machine 14 respectively provided supply rolls 10 with flat and / or foil material 16 can the packaging machine 14 each provided in a defined feed and there in the installation position 18 be used after there before the at least partially used role 24 was taken, the continuous packaging operation by at least partially exhausting the previously in the buffer 22 subsidized flat and / or sheet material 16 is maintained, as shown by the representations of 1 is illustrated. The term defined here of the defined feed can include different conveying variants, such as a horizontal conveyor belt with it to the packaging machine 14 transported new supply rolls 10 , for example, taken by means of a gripping and / or handling device such as a multi-axis robot and in the installation position 18 can be brought. However, the defined feed can optionally also be formed by driverless transport systems (so-called FTS), which are each individual new supply roll 10 with a remote-controlled self-propelled shuttle to the packaging machine 14 bring up and there with the help of an in-house handling gripper or with the help of there available gripping and / or handling system or robot in the installation position 18 in or on the packaging machine 14 deploy.

The 2A to 2D show in each case by means of schematic perspective views different handling steps when replacing the rollers 10 . 24 using a handling robot 28 , Such handling robots 28 are known as multi-axis robots in different variants. The 2A illustrates the image of standing on pallets 30 to the packaging machine 14 promoted new roles 10 with flat packaging material wound thereon 12 , which by means of a pivoting arm 32 of the handling robot 28 taken and in the installation position 18 the packaging machine 14 can be used. For this purpose, the swivel arm dives 32 of the handling robot 28 with a holding pin 34 from above in a vertical direction into a central hollow core 36 the role to be included 10 and clamps this hollow core 36 according to the role 2 B take up and towards the installation position 18 to be able to move. The swivel arm 32 of the handling robot 28 This can typically be moved with multiple degrees of freedom to the role 10 to position accurately.

Having a spent or almost used up role 24 from the installation position 18 the packaging machine 14 The new role can be taken 10 by means of the handling robot 28 in the same installation position 18 be used, as indicated by the 2C and 2D exemplified clarifies. In the field of installation position 18 is typically a horizontally rotating mandrel 38 for clamping reception and positioning of the hollow core 36 the respective role 10 available, with an electric drive motor 40 and possibly with Längsverstelleinrichtungen 42 can be equipped. The longitudinal adjustment devices 42 serve for horizontal displacement of the mandrel 38 to facilitate the insertion and removal of rolls 10 . 24 and / or for their exact alignment in the installation position 18 so that's off the roll 10 withdrawn flat and / or sheet material 16 in exact alignment with the packaging line 20 (see. 1 ) can be brought. Having a new role 10 on the mandrel 38 If necessary, it can be fixed by means of a holding mandrel 34 of the handling robot 28 attached stamping attachment 44 continue in the axial direction on the mandrel 38 be pushed until a desired target position is reached.

The handling of the stamp attachment 44 on the swivel arm 32 of the handling robot 28 is in 2D exemplified. With the help of the stamp attachment 44 can the new role 10 in the direction of the arrow against an axial stop 46 be pushed into the desired end position. This axial stop 46 may possibly also with the Längsverstelleinrichtungen 42 be coupled so that he has a variable axial stop 46 can form.

Optionally, the transection of the flat and / or sheet material 16 the approximately unwound and / or used up roll 24 from that continuously into the packaging machine 14 subsidized flat and / or sheet material 16 as well as the compound of the newly used role 10 unwound flat and / or sheet material 16 with the continuous in the packaging machine 14 subsidized flat and / or sheet material 16 largely automated. The individual, successive processes are preferably controlled centrally here, possibly supported by suitable image processing systems with which the handling robot 28 can be controlled. The handling robot 28 may have suitable interchangeable tools to both the separation and the welding of the webs of the flat and / or sheet material 16 autonomous in connection with the role change. In this way, both the removal of an approximately unwound and / or used up role 24 from their installation position 18 in the packaging machine 14 as well as the insertion of a new role 10 in this installation position 18 largely automated. The removal of used rolls 24 from the installation position 18 and / or the insertion of new roles 10 in the installation position 18 can, for example, by the in 2 shown multi-axis or handling robot 28 or by FTS or a combination of these elements.

As the schematic plan view of 3 clarifies, the installation position 18 for the roles 10 respectively. 24 with wrapping material wrapped on it 12 in the form of the flat and / or sheet material 16 optionally also outside the packaging machine 14 so that the flat and / or sheet material 16 from outside into the packaging machine 14 and in the packaging line 20 is encouraged. The mandrel 38 can be in different positions, so for example. With its longitudinal axis parallel to the conveying direction of the flat and / or sheet material 16 in the packaging line 20 so that the flat and / or sheet material 16 must be deflected by 90 °.

The in the 2A to 2D Not shown cache 22 may possibly also outside the packaging machine 14 as shown schematically in the 3 is indicated.

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.
