Description

Apparatus and method for packaging piece goods and in particular containers

description

The present invention relates to an apparatus and a method for packaging piece goods and in particular containers. From the prior art it has long been known that containers are bundled into groups of containers, for example so-called six-packs. For this purpose, different approaches are known. In a procedure known from the prior art, these containers are packaged in a film and then shrunk again, for example, in a shrink tunnel to the containers.

Recently, it has also become known to wrap such container groups by means of a stretchable film (also referred to below as stretch film). For this purpose, the containers are placed in a winding device and wrapped there by means of a stretchable film. This stretchable film is usually unwound from rolls. When emptying such a roll, a new roll of plastic sheeting must be placed in order to continue the process. Thus fall in the prior art change times, during which the machine is stationary.

The present invention is therefore based on the object to provide an apparatus and a method available in which such change times can be reduced. In particular, in this way the total working efficiency of such devices should be increased. These objects are achieved by the objects of the invention achieved independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.

A device according to the invention for the packaging of piece goods compilations has a transport device which transports a multiplicity of piece goods in a predetermined transport direction. Furthermore, the device has a first winding device, which is suitable and intended to wrap the piece goods with a film element, wherein this first wrapping device has a dispensing unit with a dispensing element circulating around the goods and wherein the piece goods can be fed to the first wrapping device, to be wrapped with the film element.

According to the invention, the device has a further wrapping device, which is suitable and intended to wrap the piece goods with a film element, whereby this further wrapping device has a dispensing unit with a dispensing element circulating around the piece goods and wherein the piece goods can be fed to the further wrapping device, to be wrapped with the film element and wherein in a working operation of the device optionally the first wrapping device and the further wrapping device are used to wrap the cargo.

It is therefore proposed that a further wrapping device is available, which can be used in particular if the first wrapping device is not active. This may be the case, for example, during repair measures, but in particular also when the first wrapping device has to be equipped, for example, with a film roll. Conversely, the first wrapping device may also be in operation while the other wrapping device is resting and being fitted with a new film roll, for example.

This dispensing element may, for example, have a carrier on which a film roll can be rotatably arranged. In addition, this dispensing element can also have deflection rollers or the like, or else a dispensing edge, from which the film element can be attached to the containers in a defined manner. It would be possible that a feed angle, under which the donation element attaches the film element to the containers, is variable. In principle, a simultaneous operation of these two Umwickelungseinrichtungen would be conceivable. It is further proposed that the further Umwickelungseinnchtung and the first Umwickelungseinnchtung are designed such that also optionally during operation, one of the two Umwickelungseinrichtungen can rest. While one wrapping device works in operation, so the other wrapping device can be repackaged. Preferably, the two wrapping devices are of similar construction. In this way, an automated assembly of the wrapping devices can be facilitated.

It would be conceivable that each of these Umwickelungseinrichtungen has two dispensing units, which may for example be arranged opposite each other. In this way, if necessary, retrofitting operations could be made even faster.

In a further advantageous embodiment, at least one wrapping device has a rigid carrier. This rigid carrier may be a carrier on which the piece goods or the piece goods flow is transported and in particular is pushed. Advantageously, this particular rigid support is also wrapped by the film element. Subsequently, the piece goods or containers that are already wrapped, be pushed back from this carrier. The film element will then be applied to one side of the containers, for example to a bottom of the containers. This carrier preferably extends in the transport direction of the piece goods or containers and in particular this carrier extends at least partially through at least one wrapping device.

The piece goods to be wrapped are, as mentioned above, in particular containers, these containers again being able to be, for example, plastic bottles, glass bottles, cans, pouches or the like. In a further advantageous embodiment, the Umwickelungseinnchtung also on side guide elements, which are also preferably wrapped with. After wrapping the container compositions can also be deducted from these side guide elements. Advantageously, these side guide elements, which may be designed, for example, bar-shaped, extend in the transport direction of the piece goods. Furthermore, it would also be conceivable that such lateral guide elements extend, for example, continuously both through the first wrapping device and through the further wrapping device. In this case, two such side guide elements could preferably be present, which limit the article flow laterally. It is again pointed out that in normal operation, preferably only one of these two Umwickelungseinrichtun- works or wrapped the piece goods compilation.

In a further advantageous embodiment, the device has a cutting or separating unit, which is suitable and intended to cut through the film element at predetermined areas. In this way, the initially endless wrapped piece goods can be portioned, about each pack with four, six or eight containers are separated. Advantageously, this separating element is designed such that it separates at defined locations, in particular between two containers, the piece goods compilations.

For this purpose, it would be possible for the cutting element to move with the piece goods compilation. In particular, while a movement of the cutting element in the transport direction of the piece goods compilations is at least temporarily synchronized with a movement of this Stückgutzzusammenstellung, so that in this way, even with continuous operation, a straight cut is possible. However, a clocked operation would also be conceivable, through which the piece goods assembly rests, while the cutting element performs a corresponding cut of the film element. In an advantageous embodiment, the separating element moves along a sawtooth-shaped movement path. It is conceivable that the separating element is initially moved synchronously with the Stückgutzzusammenstellung and quickly moved back to a starting position after a successful cut. The wrapping device advantageously wraps around the piece goods compilation in a direction running around the transport direction of the piece goods compilation. In a further advantageous embodiment, the transport direction is a straight-line transport direction. In particular, it is a horizontal transport direction. Advantageously, the wrapping device wraps around the containers or the stream of articles helically and / or spirally and in particular in a direction of rotation around the transport direction of the piece goods around. However, it is conceivable that the Umwicklungsrichtung is employed obliquely to the transport direction. In a further advantageous embodiment, the transport device has at least one conveyor belt or a transport chain. In a further advantageous embodiment, the transport device may have a plurality of transport units, which transport the piece goods in sections. Thus, for example, a first transport unit can feed the piece goods to a first wrapping device, a further transport unit can transport the piece goods from the first wrapping device to a second or further wrapping device, and a further transport device can transport the already wrapped piece goods to a separating unit or cutting unit. Preferably, the transport speeds of these transport units are at least partially synchronized with each other and / or adapted to each other.

Advantageously, the at least one separating element is arranged downstream with respect to both winding devices.

In a further advantageous embodiment, the device has a sensor device, which comprises an occupation state of the film element within at least one wrapping device. In this way, for example, the state of motion of a film roll can be detected. For example, once this film roll reaches a certain limit occupancy state, the user can be notified of an imminent change of the film roll. It would also be conceivable that - as soon as a certain occupation state of a film roll is reached - another wrapping device, for example the further wrapping device, starts to operate. In this way, a seamless transition during operation could be possible, and after the change can be converted in turn to the first wrapping device. It would also be possible for a film roll to empty initially (automatically) to another wrapping device.

By way of example, the sensor device may be a non-contact sensor device which detects an occupation state of the film rolls. It could also be, for example, a weight detection device, which For example, a weight of the film roll and thus indirectly detects a filling state. In addition, markings may be affixed to the film element itself, which indicate, for example, an early end of a film roll. These markings can be read in particular optically.

In a further advantageous embodiment, at least one dispensing unit has a receiving device for in particular rotatable receiving a film roll. Thus, for example, the dispensing unit may have at least one roller carrier on which, for example, a film roll can be pushed. In operation, this film roll can rotate and thus unwind the film element.

In a further advantageous embodiment, this receiving device is accessible to at least one dispensing unit in a running operation of the device in order to exchange a film roll for another film roll. It is possible that this receiving device is driven for a role change in a certain position in which a change is easily possible by the user. For example, a housing of the system may have a lateral opening. To change, a roller carrier can be brought to this opening to arrange a new film roll. This can preferably be done automatically and in particular also in a running operation.

In a further advantageous embodiment, the device has a changing device which allows at least partially automated changing of film carriers for equipping the Umwickelungseinnchtungen. In addition to the term film carrier, the term film roll is also used below, wherein it is pointed out that the carrier generally does not necessarily have to be a roller.

In this embodiment, therefore, it is proposed that a changing device and in particular an alternating robot are present, which allow a replacement of particular film rolls. In this way, a change process - especially during operation - at least semi-automatic, preferably also be carried out fully automatically. This changing device preferably has a gripping device arranged on a movement device for gripping and / or moving the film carrier or film rolls. In particular, this movement device can be a robot which allows a substantially free movement in the space of film carriers. light. This movement device can have a plurality of articulated arms connected to each other, which allow in this way a pivoting about several axes. Advantageously, the gripping device of the movement device can be pivoted about at least 2 and more preferably about at least 3 axes. Advantageously, these axes are perpendicular to each other. Furthermore, the changing device itself may have a particular stationary carrier, which is placed in the region of the device.

The gripping device can be a gripping device which makes it possible to grasp film rolls from the inside. These film rolls usually have in their interior a tubular cavity in which the gripping device can engage. In a further advantageous embodiment, this gripping device has a detection device which can detect the presence of a label roll on the gripping device and / or can identify a film roll.

Advantageously, this detection device can also be suitable and intended to detect parameters of the film, such as a material condition and the like. In addition, this detection device can also ensure that the film roll is sitting on the gripping device in conformity with the law of rotation in order to be used in the device or the wrapping device in accordance with the terms of rotation.

In a further advantageous embodiment, the device also has a holding device for temporarily holding and / or carrying film rolls. It is possible that such film rolls are stored by a robot device or a user on this support device. A detection device can recognize the data of the film element in this state and, for example, also check a rotational direction-compliant alignment. Subsequently, the film roll can be used with the changing device in the machine.

For example, it is possible for a robot to pick up the film rolls and place them on the carrier for inspection. It is also conceivable that the rollers are used directly in the machine or on a further storage device, such as a pallet, stored intermediately. In a further advantageous embodiment, the gripping device has an expansion element which can be expanded, in particular, in the interior of a film roll so as to grip the film roll. In another Advantageous embodiment, the device also has a receptacle for spent film rolls.

It is also possible that a film of another film carrier directly adjoins the film of an empty-running film carrier.

In a further advantageous embodiment, a further Umwickelungseinnchtung in the transport device follows directly on the first Umwickelungseinnchtung. Thus, for example, it is possible for the containers to be wrapped optionally by the first wrapping device or the further wrapping device, and by the same transport device, in particular a push transport device, by both, i. both the first and the further Umwickelungseinnchtung be transported.

In this case, it would preferably be possible for the first and the further wrapping device to lie directly against one another, for example in such a way that any elements such as drives are so aided that in this way a distance between the two wrapping devices is not increased.

It would also be possible that the dispensing unit of the first Umwickelungseinnchtung and the dispensing unit of the further Umwickelungseinnchtung relative to the transport path of the containers face each other. In this way, the formation of imbalances can be counteracted.

In a further advantageous embodiment, at least one wrapping device has an annular carrier on which the dispensing unit is arranged. Advantageously, this annular support is rotatably mounted. Advantageously, this annular support is rotatably mounted with respect to a constant axis of rotation. In this case, this support is preferably rotatable relative to a rotation axis which runs parallel to the transport direction of the piece goods. However, it would also be conceivable that an axis of rotation of this carrier runs obliquely to the transport direction of the piece goods. Advantageously, the device has a drive device which drives this rotatable carrier. In this case, this drive can preferably take place via contact with an outer circumference of this annular carrier. For example, the annular carrier can be loaded on a plurality of wheels. be gert, wherein at least one of these wheels is driven by the drive means.

In a further advantageous embodiment, the transport device has a push-ahead device, which pushes the piece goods in a working operation of at least one of the wrapping devices. Thus, it is possible that the transport device pushes the piece goods compilations on the above-mentioned rigid support and there is a continuous wrapping. Advantageously, a combination of this feed movement of the piece goods compilations and the wrapping results in a total of spiral wrapping of the piece goods.

In a further advantageous embodiment, the device has a second Umwickelungseinnchtung, which is operable in a working operation of the device at least temporarily simultaneously with the first Umwickelungseinnchtung. Thus, for example, the piece goods assemblies can be wrapped during operation of two, in particular in the transport direction of the piece goods compilations successive Umwickelungseinrichtungen. As a result, the further wrapping device is preferably also provided here, which is to be put into operation instead of the at least first or the second wrapping devices, in particular during a changeover operation. It is conceivable that the device has only one further Umwickelungseinnchtung and the film carrier are preferably equipped such that not simultaneously the film carrier of the first and the second Umwickelungseinnchtung be empty. In this way, the further Umwickelungseinnchtung depending on the occupancy state of the film rolls, the first or the second Umwickelungseinnchtung during operation replace.

In a further advantageous embodiment, the second Umwickelungseinnchtung is formed such that the parcels are wrapped in opposite directions by the first Umwickelungseinnchtung and by the second Umwickelungseinnchtung. In this way, the production of a cross winding is possible. Advantageously, both the first and the second Umwickelungseignchtung the film elements are wound spirally, but here the respective film elements are wound crosswise with respect to each other by the two Umwickelungseinrichtungen. In this way, a higher stability of the resulting product can be achieved. At least one wrapping device is advantageously suitable and determines that the dispensing unit is guided in two opposite wrapping devices around the piece goods compartments. For example, it is possible for the first wrapping device to wrap the piece goods compilations in a first circulating direction and for the second wrapping device to wrap the piece goods compilations in a second (in particular opposite) circulating direction. Depending on which of the first or second wrapping devices has to be refilled, the further wrapping device can be operated in the corresponding opposite direction of circulation.

However, it would also be conceivable that both a first and a second wrapping device, which are suitable and intended to run simultaneously in operation, in each case a further Umwickelungseinrichtung is assigned, which take over their work especially when emptying the film carrier.

In a further advantageous embodiment, the device has a drive device for generating the circulating movement of both the dispensing unit of the first wrapping device and the dispensing unit of the second wrapping device. This means that both the rotational movement of the dispensing unit of the first reeling device and the rotational movement of the dispensing unit of the second reeling device are driven by the same drive. It is conceivable that when changing the film carrier one of the two Umwickelungseinrichtungen is decoupled so as to be able to replace the film carrier in a dormant state. Advantageously, the drive device for driving the wrapping devices is an electric motor.

As mentioned above, advantageously at least one of the wrapping devices is movable in both directions of rotation. For this purpose, it may be necessary or advantageous if not only the direction of rotation is changed, but also, for example, the position of a dispensing unit with respect to the product flow. Preferably, two different positions are conceivable which are each optimized for a Umwickelungsrichtung. Advantageously, the first and the further wrapping device are temporarily synchronized in their movement with each other. Preferably, however, this synchronization can be canceled in particular for carrying out a change operation. In a further preferred embodiment, the device has a gear drive for driving the Umwickelungseinnchtungen or the dispensing units. Furthermore, it would also be possible that at least one of the Umwickelungseinnchtungen along the transport directions of the containers is displaced. Thus, for example, to change the label carrier, the entire wrapping device could be disengaged from a drive device so as to be able to replace the film rolls in a stationary state.

The present invention is further directed to a method for packaging pieces of goods, wherein a transport device transports a plurality of piece goods in a predetermined transport direction and wherein a first wrapping device, the piece goods wrapped with a film element, said first Umwicke- lungseinrichtung a dispensing unit with a to the Has piece goods encircling dispensing element, wherein the piece goods are supplied to the first wrapping device to be wrapped with the film element.

According to the invention, the device has a further wrapping device, which also temporarily wraps the piece goods with a film element, said further wrapping device comprises a dispensing unit with a dispensing element circulating around the piece goods and wherein the piece goods are fed to the first wrapping device to be wrapped with the film element and wherein in a working operation of the apparatus optionally the first wrapping means and the further wrapping means are used to wrap the piece goods.

Advantageously, a wrapping device is at least temporarily operated, while the other rests. In particular, a wrapping device is operated at least temporarily, while in the other wrapping device film elements and in particular a roll with film elements are replaced.

In a further preferred method, the piece goods are wrapped by at least two Umwickelungseinnchtungen. In particular, the wrapping with these two Umwickelungseinnchtungen takes place at the same time. This will be in a working operation to the Product flow or applied to the containers two film elements. Advantageously, these foil elements are applied in opposite directions by the two Umwickelungseinnchtungen. In this case, from the first Umwickelungseinnchtung the film element, for example, be applied in a clockwise rotation and by a second Umwickelungseinnchtung counterclockwise.

Advantageously, the film elements of the Umwickelungseinnchtungen helical or helically applied to the product stream or the containers.

In a further preferred method, a change of film element carriers from the respective Umwickelungseinnchtungen is at least partially automated by means of a changing device. Thus, it is possible that a changing device, such as an interchangeable robot, removes empty rolls from the Umwickelungseinnchtung and feeding fully occupied roles. Advantageously, these film rolls are used with a certain sense of rotation in the respective Umwickelungseinnchtungen.

Further advantages and embodiments will be apparent from the attached drawings:

Fig. 1 1 is an overall view of a device with a changing device.

FIG. 1 shows a schematic representation of a section of a packaging machine or a device 50 according to the patent. In this case, containers 1 are supplied as articles or unit streams S. The reference numeral 3 denotes a transport device which transports the containers or piece goods along the transport device T. The transport device is preferably composed of several transport units, which can also be arranged between the individual Umwickelungseinnchtungen 2 and 6 and thereafter. In the apparatus shown in Figure 1, the articles are supplied as a two-lane inlet by means of the first conveyor. This feeder can be, for example, a conveyor belt, a mat chain conveyor or the like.

The reference numeral 2 denotes a first Umwickelungseinnchtung, which serves the containers with at least one layer of a stretchable film, a so-called

Stretch film to wrap. In this case, this film element is preferably wound helically in a manner known per se to the here in pairs conveyed side by side articles or containers, with a sufficient tension of the film element for the fixed mechanical cohesion of the article or Stückgutstroms provides.

In order to ensure a trouble-free transport of the article or Stückgutstroms in the first Umwickelungseinnchtung 2, for example, circumferential feed belts (not shown) can laterally attack the article or cargo flow S, passing through the containers promote the first Umwickelungseinnchtung 2, while the containers 1 are wrapped simultaneously.

In the first wrapping means 2, for example, the containers can slide on a lower sliding plate (not shown), which is also wrapped.

The reference numeral 60 refers to a first feed module downstream of the first wrapping device, which serves for the further transport of the article or piece goods stream already wrapped with at least one layer of stretch film (typically by means of upper and lower feed belts or feed belts). These feed belts or feed belts can circulate endlessly over the length of the first feed module on the upper and lower sides of the article or Stückgutstroms and ensure its further transport to a second Umwickelungseinnchtung 6. In the second wrapping device 6, the article or piece goods stream can also be helically applied to a second layer of film elements, which preferably takes place at a different winding angle than in the first wrapping device 2 and / or in an opposite winding direction (i.e., direction of circulation). The reference numeral 61 refers to a further feed module and serves for a further transport of the now wrapped with multiple layers of stretch film article or Stückgutstroms. Again, upper and lower feed belts or feed belts can be used in turn, which rotate over the length of the second feed module 61 preferably endlessly on the upper and lower sides of the article or Stückgutstroms and cause its further transport. By this transport, a multi-layer helically wrapped with film elements and initially endless moving in the conveying direction film packaging is formed with containers 1 packed therein, wherein then the planes perpendicular to the longitudinal axis and the conveyor can optionally be provided with perforations and / or packaging between successive containers or pairs of containers or groups of several transported containers is severed. Accordingly, the reference numerals 62 and 64 refer to cutting units or separation units, which serve to separate the film elements. These two can

Cutting units 62, 64 redundant to effect higher throughput speeds. The reference numeral 66 denotes a discharge device which removes the resulting container 1. Figure 2 shows a side view of a corresponding device for wrapping containers. Here again the containers 1 are shown as well as the sliding plate or the carrier 32, on which the plastic containers 1 are pushed. The reference numeral 34 denotes side guide elements, which serve for the lateral guidance of the containers or the Stückgutzzusammenstellungen.

The reference numerals 63 and 65 designate transport devices which pull out the already wrapped containers from the first wrapping means 2 here. The reference numeral 72 roughly indicates schematically a cutting or separating element which cuts the film element. This moves in a vertical direction P1.

The reference numeral 6 again indicates the second Umwickelungseinnchtung, in which case again already bundled containers can be wrapped. The reference numerals 76 and 78 designate two further transport devices, which in turn are intended for pulling out the container from the second Umwickelungseinnchtung 6. The reference numeral 79 denotes a second cutting element, which also serves to cut the film element.

The reference numeral 82 denotes a transport unit for transporting the individual now already cut containers.

FIG. 3 shows a further illustration of a wrapping device according to the invention. Here, in addition to the two first and second Umwickelungseinnchtungen 2 and 6, in each case a further Umwickelungseinnchtung 4 and 8 shown. These two other Umwickelungseinnchtungen 4 and 8 serve to be able to continue operation, for example, in a role change of the first and second Umwickelungseignchtungen. In Figure 3, two possible approaches are shown. In the procedure shown in the left part of the figure transport means 63 and 65 are again provided between the first wrapping means 2 and the further wrapping means 4, which further transport the containers. Also, both the first and the further Umwickelungseinrichtung a sliding plate (carrier) 32 and side guide elements 34. The further wrapping device 4 can optionally be used here for the first wrapping device 2. In the case of the second and further wrapping fabrics 6 and 8 shown on the right, they are arranged directly adjacent to one another. Also here is a continuous sliding plate (carrier) 32, which may however also be designed as a delivery device, is provided. In operation, one of the two wrapping devices 6 and 8 will preferably rest, while the second wrapping will apply.

The reference numerals 63 and 65 in turn designate a conveyor unit which pulls the containers out of the wrapping means 6 and 8.

In turn, separating elements are provided, which serve for separating the container or the film elements surrounding this. In the embodiment shown in Figure 4 again first and second Umwickelungseinnchtungen 2 and 6 and each associated therewith further Umwickelungseinnchtungen 4 and 8 are provided. In these illustrations too, the first wrapping device 2 and the further wrapping device 4, on the one hand, and the second wrapping device 6 and the further wrapping device 8, are arranged together or directly one behind the other.

In a further embodiment, not shown, it would also be possible for a first wrapping device 2 and a second wrapping device 6 as well as a further wrapping device 4 to be provided. In this case, this further wrapping device 4 could be arranged in the transport direction T between the first wrapping device 2 and the second wrapping device 6. Depending on the idling of the roller, this further wrapping device could optionally take over the operation of the first wrapping device 2 or the second wrapping device 6. FIG. 5 shows a further schematic representation of a device according to the invention. In this device, three Umwickelungseinnchtungen 2, 4, 6 are shown here. In addition, however, could be followed by other Umwickelungseinnchtungen especially on the right side. Between these individual Umwickelungseinnchtungen each transport or conveyors 63, 65 are shown. This may in particular Feed devices act which pull out the containers, for example, from the Umwicke- means 2, 4. The reference numeral 15 denotes a film roll. The wrapping device 4 can be used here if film rolls have to be exchanged in the first wrapping device 2 or the second wrapping device 6. For this purpose, at least the further wrapping device 4 is suitable and intended to be operated in different Umlaufrichten.

FIG. 6 shows a roughly schematic representation of a wrapping device. This has a designated in its entirety by 25 annular support which is rotatable here along the arrow P2 in the corresponding direction of rotation. On this carrier a roughly schematically and drawn only in its entirety dispensing unit 30 is arranged. This has a dispensing element or a receiving device 31, on which, for example, a roll 15, which is shown only schematically, is arranged with a film element 12 which can be unrolled therefrom. Again, the carrier 32 is shown, which is mitumwickelt and the side guide elements 34. After wrapping - as mentioned above - the piece goods compilation 10 of the carrier 32 and the side guide elements 34 deducted. The reference numerals 92 and 94 designate wheels which serve to support the revolving carrier 25. In this case, one of these wheels can also be driven.

As mentioned, it is preferably also possible that the carrier 25 can be moved in two different directions of rotation. It is also preferably possible that the carrier roll can be arranged with the film element in two ways on the left or right side of its rotatable support 31 to control the Umwickelungsrichtung accordingly.

Advantageously, a rotational speed of the carrier 25 is synchronized with the feed rate of the piece goods compartments 10.

FIG. 7 schematically shows a changing device 100 for changing film rolls 15. This changing device 100 has a gripping device 102, which can grip the film roll 15 for alternating operation. Advantageously, this gripping device 102 has an inner gripper, which can be pushed into an opening 15 (see FIG. The- se gripping device is arranged on a pivotable arm 108. This pivotable arm 108 is in turn arranged via a joint 106 on a further, likewise pivotable arm 104. The reference numeral 1 10 denotes a main carrier of the changing device. By means of the multiplicity of joints shown here, a pivoting of the gripping device about a plurality of axes, here in particular about at least three axes which are in particular mutually perpendicular, is conceivable in particular. In this way, the film roll 15 can be arbitrarily positioned in a certain work area.

The reference numeral 120 denotes a detection means which can detect, for example, data of the film roll 15, such as a sheet material or a coating state or the like.

FIG. 8 shows a detailed representation of a change device 100. Here, again, the arm 108 can be seen, on which the gripping device 102 is arranged. As a result of the degrees of freedom of movement, the film rolls 15 can be gripped in their openings 15 and thus be lifted, for example, by a pallet.

FIG. 9 shows an illustration of a film roll 15 arranged on a carrier 140. This film roll here has a marking 128, which indicates a unwinding direction. In addition, further markings 127, 129 can be provided, which enable an optical detection device to have a precise alignment of the film roll. The reference numeral 126 schematically (not shown in more detail) another marker from which, for example, properties of the label roll, such as a material can be read. This could be, for example, a barcode, a QR code or the like. Reference numerals 122 designate side guide elements, which can for example also be adapted to a width of the film roll 15.

FIGS. 10a to 10c show further illustrations of the film roll 15 arranged on the carrier 140. Here, too, the side guides 122 are recognizable. The reference numeral 142 denotes an upper edge of the carrier, which ultimately limits the receptacle for receiving the label roll.

Figure 1 1 shows a further overall view of a device according to the invention with a change device 100. In this case, a user B can change this semi-automatically or make manually, but ultimately advantageously serves the changing device 100 to accommodate the individual film rolls 15 and the entire device 1 supply.
