Description

• einer Transporteinheit zum Transportieren des Verpackungsverbunds in eine Transportrichtung und
• einer den Verpackungsverbund mit dem Zuschnitt in Transportrichtung derart umhüllenden Umhüllungseinheit, dass ein vorderes Ende und ein hinteres Ende des Zuschnitts an der Transporteinheit anliegend überlappend angeordnet sind, wobei

• a transport unit for transporting the packaging composite in a transport direction and
• a wrapping unit which envelops the packaging composite with the blank in the transport direction in such a way that a front end and a rear end of the blank are arranged in an overlapping manner adjacent to the transport unit, wherein

the transport unit has a wrapping tape arranged in the area of the overlap unit for transporting the packaging composite along a transport level from a wrapping tape inlet to a wrapping tape outlet.

The invention further relates to a method for checking and/or treating a blank enveloping a packaging composite by means of a functional unit using a device of the type mentioned above.

Devices and methods for packaging groups of individual packages combined to form a packaging composite, such as beverage cans, bottles, cartons or the like, into a blank made of a shrinkable film material are from the prior art, for example DE 10 2008 052 633 A1 , already known in various designs. A defined number of individual packs are grouped in a predetermined manner and then wrapped in a film blank in a transport direction to form a film overlap. To form a film wrap that is closed on all sides, folding tabs protruding from the packaging composite on both sides are then placed laterally on the packaging composite using a folding unit. By subsequently shrinking the film, a container designed as a stable packaging unit is created, in which the individual packs are fixed relative to one another.

In the present case, liquid containers are to be understood as meaning the known primary packaging for drinks and liquid foods, such as in particular bottles, cans, cups and bag packaging (pouch) or cubic cardboard packaging with or without a spout. These liquid containers can be made of one or more known materials, such as glass, plastic, metal or cardboard.

The packaging composite is transported through the wrapping unit using a wrapping belt that forms a transport level. To wrap the packaging composite with the blank, the front end of the blank is arranged in the area between the packaging composite and the wrapping tape, whereby the front end of the blank is fixed on the wrapping tape via the packaging composite. In the wrapping unit, the rear end of the blank is subsequently folded around the packaging composite in a circumferential direction corresponding to the transport direction, the rear end being guided through a transport plane determined by an upper side of the wrapping belt in the area between the wrapping belt and a transport belt that follows in the transport direction. The rear end is then placed in the transport plane, overlapping the front end on the underside of the packaging composite in relation to the position of use.

Unless otherwise described, the term conveyor belt in this case is understood to mean any conveyor or a plurality of conveyors arranged in or transversely to the transport direction, which is suitable for the group of individual packs with or without an underlying carrier element, such as a tray, a cardboard blank or the like, to promote in the transport direction.

The use of plastic packaging is increasingly viewed critically from an ecological perspective. This applies in particular to the use of such film packaging, which, as is often the case with the containers produced using the generic devices and methods, cannot be reused. After that, as a rule, it doesn't make any sense If the plastic film used is recycled, its use for the production of containers is considered to be particularly disadvantageous from an environmental point of view.

The EP 1 227 040 A1 shows a machine for packaging stacks of sheets, with a feed unit for feeding the stack along a given path, a supply unit for feeding sheets of packaging material and for arranging a sheet of packaging material along the path of the stack, and a folding spindle along the Path is arranged to fold the sheet of packaging material into a U around the stack. Each stack is defined by sheets stacked to form a rectangular base prism of a given height and includes two base surfaces defined by corresponding end sheets, two side surfaces perpendicular to the base surfaces, and two end surfaces. The feed unit includes a first conveyor for pushing the stack on the folding spindle in a feed direction parallel to the base surfaces and the feed unit includes a conveyor for holding the sheet of packaging material transversely to the feed direction on the folding spindle.

When using packaging material blanks made of environmentally friendly, but non-shrinkable materials to produce containers, the problem is that in order to produce a container designed as a stable packaging unit, a tight contact of the blank on the packaging composite, which is essential for this and can be achieved with a suitable wrapping unit, is required by a reliable fixation of the packaging rear end must be secured to the front end. For this purpose, for example, functional units designed as adhesive units can be used, which apply an adhesive to an outside of the blank in the contact area with the rear end. Due to the arrangement of the front end in the area between the packaging composite and the wrapping tape, however, due to the flat design of the wrapping tape, there is only a narrow area between the end of the wrapping tape and the beginning of a removal belt adjoining the wrapping tape for applying the adhesive to the blank The area of its front end is available before it is covered with the rear end. An application of adhesive in the area between the wrapping tape and The removal belt therefore has the risk that the adhesive is not sufficiently arranged on the blank, so that the rear end is not sufficiently fixed to the front end.

Proceeding from this, the object of the invention is to enable a reliable application of adhesive to a blank arranged in the area between a wrapping band and a packaging composite.

The invention solves the problem by a device with the features of claim 1 and a method with the features of claim 9. Advantageous developments of the device are specified in the dependent claims 2 to 8. Advantageous developments of the method are specified in the dependent claims 10 to 12. The features or combinations of features contained in the claims are declared to be part of the description.

What is characteristic of the device according to the invention is that the wrapping tape has a plurality of individual tapes running in the transport direction, arranged parallel to one another and at a distance from one another to create free space, the wrapping tape having a first group of individual tapes designed as solid tapes extending from the wrapping tape inlet to the wrapping tape outlet and a second group from the wrapping tape inlet to an end region forming a free space in front of the wrapping tape inlet, has individual tapes designed as partial tapes, and in each case a partial tape is arranged adjacent to a full tape.

Basically, the wrapping tape extends from a wrapping tape inlet, where it takes over a packaging composite of grouped individual packs to be wrapped, to a wrapping tape outlet, at which the packaging composite, which has at least largely been wrapped into the blank, is transported away from the wrapping unit. According to the invention it is provided that the wrapping tape is not formed from a single tape body, but rather has at least two types of individual tapes which have different lengths. The individual tapes designed as solid tapes extend from the wrapping tape inlet up to the wrapping tape outlet. In contrast, the individual belts designed as partial belts also extend from the wrapping tape inlet only to an area in front of the wrapping tape outlet, ie the partial tapes end - viewed in the transport direction - at a distance in front of the wrapping tape outlet. As a result of the alternating arrangement of partial belts and full belts transversely to the transport direction, the wrapping tape has a section in an end region facing the wrapping tape outlet over which only the full tapes extend. As a result, sufficiently large free spaces are provided in this area between the solid belts, while maintaining a sufficient transport effect compared to the packaging composite, via which suitable functional units can come into effective connection with the blank. For example, the free spaces enable the convenient application of adhesive by means of a functional unit designed as an adhesive unit through the wrapping tape onto the blank that is in contact with the wrapping tape. The adhesive application can thus be carried out in a way that ensures particularly reliably that a rear end placed next to the front end of the blank is reliably fixed, so that a tight arrangement of the blank that can be generated by the wrapping unit is maintained on the packaging composite.

The packaging material from which the blank is formed can be, for example, a paper material. In other words, the blank may consist of a paper material.

The dimension of the end region of the wrapping tape resulting from the different lengths of partial tapes and full tapes, in which a transport effect is only achieved via the full tapes, is fundamentally freely selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the partial bands are 10% to 50%, preferably 20% to 40%, particularly preferably 25% to 35%, shorter than the full bands. This embodiment of the invention provides a sufficiently long end region of the wrapping tape - viewed in the transport direction - in which the free spaces are determined by the distance between the solid tapes and through which adhesive can be reliably applied to the blank can be done, which is suitable for ensuring reliable fixation of a rear end of the blank placed on the front end.

The arrangement of a functional unit, for example an adhesive unit for applying adhesive to the blank or other functional units that interact with the blank, can in principle take place at any point in the end region, provided that the desired interaction with the blank is achieved. According to an advantageous development of the invention, however, a functional space is provided to accommodate a functional unit, which is spanned below at least one working strand of the full belts and between the rear end or rear deflection of at least one of the partial belts in the transport direction and the rear end of at least one of the full belts. Preferably, the functional space extends over an area between a rear deflection in the transport direction of at least one partial belt and the removal belt, in particular between a working strand and an empty strand of the full belts, and transversely to the transport direction.

The arrangement of a functional unit in a free space delimited according to this development of the invention ensures a particularly reliable interaction of the functional unit with the blank due to the spatial proximity to the blank. Incorrect interaction between the functional unit and the cut can therefore be avoided particularly reliably.

This applies in particular to the arrangement of the functional unit in an area delimited by the empty strand and working strand of the solid belts, with the functional unit then - based on the position of use - being arranged below the solid belts moving in the transport direction and above the solid belts moving against the transport direction in the immediate vicinity of the blank, where they can interact particularly reliably with the blank via the free spaces.

The design of the functional unit that can be arranged in the free space and interacted with the blank is freely selectable. According to a further embodiment of the invention, however, it is provided that by means of at least one Functional unit in the functional space at least one end of the blank can be detected by sensors and / or monitored and / or treated, in particular an adhesive can be applied.

The possibility of arranging one or more functional units offers a particularly reliable interaction of the individual functional units with the blank. For example, the blank can be detected particularly error-free via a suitable functional unit designed as a sensor unit. An adhesive activation or an adhesive application can be effected particularly precisely by a functional unit designed as an adhesive unit, with the adhesive unit acting on the blank in a corresponding manner during an adhesive activation. The sensor units enable tactile or non-contact position detection of the blank on the wrapping tape.

The arrangement of the adhesive unit for applying an adhesive to the underside of the packaging composite can basically be done in any way compared to the wrapping tape. According to a particularly advantageous embodiment of the invention, however, it is provided that the functional unit designed as an adhesive unit for applying adhesive to the underside of the packaging composite is arranged in the area of the free spaces. An arrangement in the area of the free spaces, for example in such a way that the adhesive unit is arranged within the surrounding solid belts, enables a particularly precise application of the adhesive to the blank. For this purpose, the adhesive unit can have suitable nozzles which ensure a predetermined application of adhesive in the areas of the blank intended for this purpose.

According to a further embodiment of the invention, it is provided that the wrapping tape has a protective plate that shields the partial tapes from the adhesive unit in the area of a tape deflection of the partial tapes facing the wrapping tape outlet. According to this embodiment of the invention, a protective plate is arranged between the belt deflection of the shorter partial belts, which protects the partial belts, in particular the deflection area, from loading with an adhesive resulting, for example, from a spray mist. One Contamination of the outer sides of the partial belts that are in contact with the packaging composites with adhesive is thus effectively prevented.

In order to increase the safety of the adhesive application to the blank, according to a further embodiment of the invention, a functional unit designed as a sensor unit for detecting the packaging composite is provided in a working area of the adhesive unit. The sensor unit can reliably detect the arrangement of the packaging bundle in the end region of the wrapping tape, in which an adhesive is applied to the blank, for example at points or distributed in a predetermined manner, using the adhesive unit. The sensor unit thus additionally increases the reliability of the adhesive application to the blank in an area provided for this purpose.

According to a further embodiment of the invention, it is further provided that the transport unit has a removal belt that adjoins the wrapping belt in the transport direction, the wrapping belt having such a higher belt speed, in particular 1.25 to 2 times higher belt speed, than the removal belt that the rear end of the blank is pretensioned towards the front end of the blank when the packaging composite moves from the wrapping belt to the transport belt.

According to this development of the invention it is provided that the removal belt and the wrapping belt have a belt speed that differs from one another, with the removal belt arranged behind the wrapping belt in the transport direction having a lower belt speed. During transport through the wrapping unit in the transport direction, the packaging composite is temporarily in engagement with both the removal belt and the wrapping belt. During this transfer of the packaging composite from the wrapping belt to the transport belt, the rear end of the blank is guided under the front end of the blank. Due to the slower belt speed of the removal belt compared to the wrapping belt, the blank, for example a paper blank, is placed under tension and tightened, with a folded rear end of the paper blank towards the front end is drawn. Overall, this ensures that the paper blank rests tightly against the packaging composite in a circumferential direction of the packaging composite that corresponds to the transport direction. This makes it particularly convenient to produce a container designed as a stable packaging unit using a packaging blank made from paper material, which is a significantly more environmentally friendly packaging material than plastic materials.

The method according to the invention for monitoring and/or treating a blank enveloping a packaging composite by means of a functional unit using a device according to the invention or a further development described above is characterized in that the functional unit is located in an end region on a side of the wrapping tape facing away from the blank, in particular in a functional space between a working strand and an empty strand of the solid belts, and comes into operative connection with the blank through the free space formed between the solid belts.

The arrangement of the functional unit in the manner provided for in the method according to the invention enables a particularly error-free interaction of the respective functional unit with the blank due to its arrangement in the immediate vicinity of the blank to be processed, treated or monitored. If the functional unit is designed as a sensor unit for detecting the blank in the end region of the wrapping tape, the detection can be carried out particularly reliably through the free spaces in a tactile or non-contact manner, for example using suitable optical sensors. The free spaces also allow an adhesive unit to reliably activate, for example, an adhesive already arranged on the blank or to apply an adhesive to the blank in a precisely predetermined manner using suitable nozzles. The method according to the invention thus enables particularly reliable processing, monitoring and/or treatment of the blank by the functional unit provided for the respective process.

Particularly advantageously, it is provided that the functional unit detects the blank using sensors, monitors it optically and/or treats it, in particular applies an adhesive to the blank. Functional units that are designed to carry out several processes, but also individual functional units that are arranged in a suitable manner adjacent to one another in the functional space can be used.

According to a particularly advantageous embodiment of the invention, it is further provided that the functional unit is adjusted relative to the blank. An adjustment of the functional unit relative to the blank within the free space enables an exact alignment of the functional unit relative to the blank, so that the respective work processes to be carried out by the blank can be carried out particularly reliably.

It is particularly advantageous if one of the functional units acts as a sensor and is, for example, a laser position sensor or a camera which detects and monitors the relative position between one or more individual packs and one or more sides of the blank. Alternatively, the adhesive applied to the blank can also be applied together with the individual packs or one or more sides of the blank. The data obtained in this way can then be used advantageously for control purposes, such as the alignment and orientation of the blank or also for the discharge, for example discharge quantity, of the adhesive. If a hot or melt adhesive is applied, one of the functional units can advantageously be a thermal imaging camera. On the one hand, the presence of the adhesive, the actual temperature and the surface expansion and thus the amount of adhesive can be monitored and subsequently controlled.

The central control and regulation units are not described further, but are useful to provide.

Figure 1 shows in a perspective view and Figure 1 in a side view a wrapping unit 6 of a device 1 for the production of containers from individual packs.

For transporting a packaging composite 2 made up of individual packs grouped together via a conveyor belt 14, the wrapping unit 6 has a wrapping belt 12, which transports the packaging composite 2 from a wrapping belt inlet 26 of the wrapping belt 12 adjacent to the conveyor belt 14 to a wrapping tape outlet 27 following in the transport direction 7 , at which the wrapping belt 12 is transferred to a subsequent removal belt 13. Within the wrapping unit 6, the packaging composite 2 is wrapped into a blank 3 formed from a paper material. The Packaging composite 2 stands on a front end 5 of the blank 3 resting on the wrapping tape 12.

During the transport of the packaging composite 2 from the wrapping tape inlet 26 to the wrapping tape outlet 27 adjacent to the transport belt 13, the blank 3 is wrapped around the packaging composite 2 with its rear end 4 in the transport direction 7. For this purpose, the wrapping unit 6 has a guide rod 9 that can be brought into engagement with the blank 3 and is guided around the wrapping tape 12 on guide rails 8 arranged laterally adjacent to the wrapping tape 12.

On the movement path of the guide rod 9, it guides the blank 3 with its rear end 4 through a passage opening 17 in the area between the wrapping belt 12 and the removal belt 13 into an area below a transport plane 11 formed by the top of the wrapping belt 12, where the rear end 4 is placed on an underside of the packaging composite 2 at the front end 5 (cf. Figures 3a to 3c ).

The wrapping belt 12 of the transport unit 10, which has the conveyor belt 14, the removal belt 13 and the wrapping belt 12, is formed from several full belts 21 and partial belts 22 arranged parallel to one another and rotating in the transport direction, which are arranged alternately parallel to one another. The partial belts 22 have a shorter length than the full belts 21 which extend to the wrapping tape outlet 27, whereby the wrapping tape 12 causes the packaging composite 2 to be transported solely via the solid tapes 21 in an end region 28. In the end region 28, the wrapping band 12 thus has free spaces 24 formed between the solid bands 21.

In the end region 28 of the wrapping tape 12, a functional unit designed as an adhesive unit 18 is also arranged on the side of the solid tapes 21 facing away from the packaging composite 2 in a functional space 29 delimited by a working strand and a slack strand of the solid ribbons 21, by means of which an adhesive is applied in the area of the free spaces 24. For example, a glue is applied to the front end 5 of the blank 3.

The functional space 29 is indicated by a dashed line in some of the figures. For this purpose, the adhesive unit 18 has nozzles aligned in the direction of the packaging composite 2 in the area of the free spaces 24. Via this, an adhesive conveyed from a tank 20 via a pump 19 is applied to the underside of the packaging composite 2. When the packaging composite 2 is transported further from the wrapping unit 6, the packaging composite 2 is transferred from the wrapping belt 12 to a downstream conveyor belt 13. The rear end 4 is fixed to the front end 5 of the blank 3 in the area of the adhesive applied to the front end 5 .

A functional unit directed through the free spaces 24 and designed as a sensor unit 15 serves to detect the packaging composite 2 in the end region 28 of the wrapping tape 12, in which an adhesive can then be reliably applied to the blank 3 in the region of the front end 5 via the adhesive unit 18 (cf . Figure 4 ). To protect the partial belts 22 from an application of adhesive due to an adhesive mist and to protect a belt drive 23, a protective plate 25 is used, which in particular protects the top side of the partial belts 22 that can be brought into contact with the packaging composite 2 from an unwanted application of adhesive. The adhesive unit 18 and the movement of the wrapping belt 12 and the removal belt 13 are controlled via a controller 16 (cf. Figure 5 ).
