Description

Device and method for wrapping groups of containers

The invention relates to a method and a device for producing a container covered with a web material as outer packaging according to the

Preambles of claims 1 and 9.

The production of containers from containers with an outer packaging, which fixes the containers in a fixed position relative to one another, is well known. A group of containers, for example from at least four sides, is covered with a web material, such as a paper web or a shrink film. In the case of a shrink film, the film is then shrunk so that the containers are held firmly together by the web material. During the shrinking process, additional film overlaps are placed on the front of the container, creating a shrinking eye. This can lead to wrinkling in the area of the end faces, which the end customer calls

Lack of quality is interpreted. The shrinking process also frequently causes the problem that the film cuts on the front and back of the container, i. H. on the main surfaces, also distort or crease. Especially when using printed foils, the printed motifs are often illegible.

Similarly, when wrapping and folding a textile and / or paper web, tensioning and tensioning of the web material is required, whereby the problem often arises that the web material on the front and back of the container, ie on the main surfaces, is also distorted, folds occur or are desired Supplements of pictures or samples of adjacent partial areas are lost. Especially when using printed web materials, the printed motifs are often distorted or illegible. The invention is therefore based on the object of providing a method and a device which enable an improvement in the packaging appearance, in particular in the case of a maximally closed shrinking eye or a folding package, a distortion-free motif on a container and a minimization of the formation of folds in the region of the end faces of the container .

The object is achieved by a device with the features of claim 1 and a method with the features of claim 9. Advantageous

Further developments of the invention are specified in the dependent claims.

According to the invention, the device for locating one with a

The material of the wrapped container has at least one container transport device which transports the container through a folding and / or wrapping device, the folding and / or wrapping device passing an enveloping element above and below the at least one container transport device

Recording the web cut and for wrapping the container with the

Includes web cutting, and for transporting the web material and the

A material transport device with a first transport path is provided, which extends from a dispenser for the web material to a designated contact area of the folding and / or wrapping element with a material blank and with a subsequent second one

Transport route is provided, which connects to the first transport route and extends to the end of the bundle transport device, and a cutting station designed for cutting a web material to form the web blank with a transport device arranged upstream thereof for transporting and feeding web cuts onto and above one of the

Container transport device formed transport plane, wherein an adhesive application device is arranged in the region of the transport route, which for

Application of adhesive is formed on the inside of the web blank and in the area of the longitudinal side edges of the film blank. Alternatively, especially in the case of web cuts from a paper and / or cardboard material, the

Web cuts also stacked and already cut to size on one Template unit are provided, from where they are individually directed to the transport device via a detection and overtravel unit.

The core of the device is an adhesive application device that can be easily integrated into an existing folding and / or wrapping device.

Surprisingly, this is achieved by means of an adhesive application device which applies the adhesive to the web material or the web blank and not to the container. This makes it possible to arrange the adhesive application device, which uses the space of the folding and / or wrapping device particularly effectively.

The adhesive is applied by the adhesive device in such a way that the web cut on the end faces of the package to be wrapped with the

Containers of the container, in particular the corner containers is glued. In this way, the web blank is fixed before the shrinking process, which at least largely prevents distortion of the web blank and thus, for example, also distortion of a motif printed on the web blank. The fact that the glued sheet blank is drawn significantly less towards the front and back of the container during the shrinking process also creates a particularly small shrink hole with low film consumption and there is a significantly smaller amount of wrinkles during the sheet blanking. The film of the sheet blank is designed as a shrink film. After wrapping, the container is transferred from the container transport device to a laxative

Guided transport device and transported to a device for shrinking the web blank.

The discharge transport device, the container transport device and also a transport device feeding a container onto the container transport device are, for example, designed as conventional conveyor belts from the area of the beverage industry, whereas the film transport device can, for example, comprise vacuum tables. Containers in the sense of the invention are, for example, bottles, cans, tubes, each made of metal, glass and / or plastic, in particular PET bottles, but also other packaging materials, in particular those which are suitable for filling liquid or viscous products. In particular, beverage containers among the

Containers are understood. A bundle is made up of a group of

summarized containers formed. The containers of the package are arranged in nesting or non-nesting position. In connection with the invention, the term container can be understood to mean not only a group of containers in which the containers are already connected to one another, but also a group of containers whose containers are assembled but not yet connected to one another and which are only intended to be connected to one another by the film wrap.

In the case of a film wrapping, the folding and / or wrapping device comprises a wrapping element that comes from the first transport route

Picks up the film blank, slides along the outside of the film blank and overhauls the container during transport on the container transport device, whereby the inside of the film blank is placed against the container. Before the film blank is picked up by the wrapping element, the film blank coming from the transport device can be placed with a front edge on the container transport device and the container placed on the inside of the film blank in the area of the front edge.

To fold the film blank around the container, the wrapping element appears after the container group has been set up on the front edge from below the container transport device, lies on the outside of the film blank, guides the film blank around the container and dips back under the at the end of the container transport device Container transport device. With the end of the wrapping, the container can be on the front edge of the

Foil blank opposite flinter edge of the foil blank can be set up. After the impact, it is transported on to a

Shrinking device, for example a shrink tunnel. The container is therefore face up on the

Container transport device transported, while the wrapping of the bundle starts from the rear around the bundle. The enveloping element can be designed, for example, as a circumferential rod element.

Cutting stations are also known. On them, for example, a

Roll material of the shrink film is unrolled and cut into film blanks. The film cuts of the film are on the transport device, which - as already mentioned - can include a vacuum table, for example

Transport level of the container transport device transported. There, a front edge of the film blank is picked up by the wrapping element.

The front edge is that when transported on the film transport device in

Direction of conveyance arranged in the front edge, while the flinter edge that of

Leading edge is opposite edge of the film blank. The leading edge and trailing edge are aligned transversely in the conveying direction. The longitudinal side edges are the lateral longitudinal edges aligned in the conveying direction, i.e. the side edges extending from the front edge to the rear edge. Among the

In the context of the invention, longitudinal side edges are understood in particular to mean an area of the film blank that extends from the actual outer edge of the film (of the film blank) by, for example, several cm inwards to the opposite side edge and, in the wrapped state, lies against the front side of the container. The end face of the container is the side surface of the container on which the shrink hole is created. The film blank is glued to the containers of the container in the region of the end faces of the container, ie in the region of the open longitudinal side edges of the folded film blank. The gluing takes place in particular with the corner containers of the container. Wrapped longitudinal edges of the film preferably do not abut or overlap, so that the packs are film-free at least in some areas on the front side and the shrink hole is formed. In the event that the web material is a paper or cardboard blank, the aforementioned is used analogously, but in particular none

Shrink tunnel is required.

Furthermore, it may not be necessary for wrapping to take place in which the front of the container is transported on the container transport device while the container is being knocked in starting from the container

Back around the container, made by a circumferential rod element. In this case, other folding tools and folding processes for paper and / or cardboard blanks known in the prior art are used.

However, it can be advantageous for the folding and wrapping device to comprise suitable tension and / or tensioning elements in order to secure one over a

Container group, to tighten or stretch a container group or paper or cardboard blank placed on a container group at least in one spatial direction, ideally in two spatial directions, once or several times.

Adhesives or adhesives in the sense of the invention can be any materials or masses with which an adhesive connection can be produced between the film and the containers of the container or between two sections of the film. In particular, the adhesives or adhesives are formed from the group of hard-working or hot-melt adhesives.

The conveying direction is the direction of transport of the web material or

Web cutting, starting from the dispenser unit to the container completely encased in a web blank.

The transport level can be understood to mean the level formed by the container transport device, in which the container is transported by the container transport device. The containers can be transported on the

Container transport device, for example a container transport table, one

Conveyor belt or the like, get up. The contact area is the area along the conveyor path in which the folding and / or wrapping element comes into contact with the web blank.

According to a further development of the invention, the first transport route comprises a partial route section which extends in the conveying direction from the cutting station to the end of the transport route, in the region of the partial route section, in particular below the transport plane of the containers, the

Adhesive application device is arranged.

The first section section therefore also includes in particular the first

Transport device for feeding the film blanks onto the transport plane formed on and above the container transport device.

The adhesive application device is particularly preferably arranged in the region of the first transport device. This can in particular be a part of the first section section and thus be arranged in the vertical direction below the transport plane of the containers. The adhesive is applied particularly easily to the inside and the long side edges of the web blank. It should be noted that depending on the transport route length of the first

Partial section, the adhesive can also be applied to the inside of the (not yet cut) web material (foil, paper, cardboard, ...) if, for example, the web material has already been unrolled from a dispenser roll with a first section, but the Separating cut to produce the web cut has not yet been made. In this respect, the application of the adhesive to the web section can also be understood to mean an application to the web material that has not yet been cut, but shortly thereafter.

The adhesive is applied to the web blank in the area of

Material transport device. According to a development of the invention, it is provided that the device for applying the adhesive is designed in the end region of the first transport device and before the web cut is fed onto the container transport device. The last third of the first is in particular below the end region of the first transport device Transport device, for example a vacuum table, or the transition region between the end of the first transport device and the

Container transport device understood. This ensures that the adhesive is only applied to the web material or the web blank shortly before the container is wrapped, thereby preventing, for example, incorrect sticking.

Ideally, the adhesive application device is for the application of

Suitable adhesives that belong to the group of hot or hot melt adhesives. The application is carried out contactlessly using application nozzles or spray heads. As a rule, one application nozzle or one spray head is provided for each application site, so that they do not have to be moved or swiveled while the system is running. An application nozzle or a spray head can be applied to the conveyed

Apply web material or a web blank, in a row at certain points or in lines, an adhesive.

The application nozzles or spray heads are associated with known ones

Storage tanks, heaters, pumps, etc. are connected and are fed by these.

According to a development of the invention, at least one adhesive head of the adhesive application device is movable transversely to the conveying direction of the web blank. The adhesive head can thus be moved between the longitudinal side edges of the web blank, so that by means of an adhesive head on both

Longitudinal edge areas of adhesive can be applied. Also, by means of the movable adhesive head, adhesive can be applied to areas of the

Web cut between the longitudinal side edges are applied, so that, for example, additional gluing of the web cut to one another or the web cut to the containers of the container can be achieved. In order to increase the throughput speeds of the device, for example, the adhesive application device particularly preferably has at least two

Glue heads on opposite sides of the first

Transport device are arranged. As a result, the adhesive can be applied to both longitudinal side edges of the web blank without any

time-consuming movement of the adhesive head must be done. The time required to move the adhesive heads back and forth is eliminated.

In addition, however, both adhesive heads can also be movably supported transversely to the direction of transport, as a result of which adhesive can be applied particularly quickly to areas of the web blank lying outside the longitudinal side edges. Of course, other adhesive heads, for example a third or fourth adhesive head, can also be arranged.

In order to make optimal use of the installation space of the device, the

Cutting station in the vertical direction below the transport plane of the container (container transport device, feed transport device) be arranged so that the web cut for wrapping the container coming from below on the

Container transport device is guided. In order to be able to make optimal use of the installation space of the device and, in particular, not to hinder the transport path of the containers on the respective transport device, it can be provided, as already stated, that the adhesive application device is arranged in the vertical direction below the container transport device.

Just like the cutting station, the adhesive application device can also be offset in the horizontal direction from the container transport device and, for example, directly under a feed transport device that places the container on the

Container transport device passes, be arranged. In order to ensure a particularly exact positioning of the longitudinal side edges of the web blank provided with the adhesive on the end faces of the container, according to a further development of the invention it is provided that a pressing element (scraping element) is arranged which has a material protrusion with the longitudinal side edges after the wrapping on the end faces of the container moves. The pressure element exerts pressure against the

Material protrusions present on the end face area and thus also against the longitudinal side edges of the web blank provided with the adhesive, whereby the material protrusions move around the corner containers of the container and the protruding material protrusions of the web blank are pressed against the front side of the bundle. The fact that the adhesive on the

Long side edges with the containers of the container, in particular the

Comes into contact with corner containers, the sheet blank, for example the

Foil cutting with the containers. The pressing element can also be used

Be rubbing element. For example, rollers or brushes on which the container is provided are provided as the pressing or brushing element

is led past. In addition to a passive bypassing, an undertaking can also be understood as an active guiding of the container to the pressing element or the pressing element to the container. Of course, several pressure elements or on both sides of the container

Pressure elements can be arranged.

The object is further achieved by a method for producing a container wrapped with a sheet blank, comprising the steps of: transporting the sheet blank on a first transport device of a film transport device from a cutting station to a transport level formed on and above the container transport device, enveloping a container transported on the container transport device, wherein the web blank is gripped by a wrapping element and is moved around the container during transport, wherein during the transport of the web blank in the region of the first transport device onto the web blank in the region of the inner surface and in the region of the

An adhesive is applied along the longitudinal edges of the web blank and the Longitudinal edges of the sheet blank are glued to the end faces of the container after wrapping.

The application of the adhesive to the sheet blank instead of to the containers enables a particularly space-saving arrangement of one

Adhesive application device. The adhesive application device can in particular be integrated into the existing installation space of the folding and / or wrapping device. The glue also fixes the open ends of the web blank to the front of the container in front of the

Shrinking process achieved by which distortion of the web cut on the front and back is avoided by the shrinkage. This can prevent the motif from being distorted, particularly in the case of the web blanks which are used with particular preference and printed with a motif. In addition, the bonding causes the formation of a largely closed shrinking eye with the smallest possible amount of film, in which wrinkling is largely avoided.

In order to apply and glue the film protrusion in the wrapped container particularly precisely to the end faces of the container, it is provided according to a further development of the invention that a pressing element moves a film protrusion in the wrapped container with the longitudinal side edges to the end faces of the container. The film protrusion is applied around the corner containers of the container to the front sides of the container and the adhesive applied to the longitudinal side edges is glued to the containers, in particular the corner containers of the container.

As already mentioned, the web blank used is printed with particular preference, for example with a motif from a manufacturer. Due to the improvement in the shrinkage pattern due to the gluing of the sheet blank before shrinking, the containers can be produced particularly preferably as containers free of banderoles. This means that there is no longer any need for a banderole with a corresponding motif to be arranged under the film, since this is printed on the web blank. To keep the effort of applying the adhesive as low as possible, and

To avoid incorrect adhesive bonds due to excessively large adhesive sections, it is provided according to a development of the invention that the adhesive as

Glue centers are applied. This means that the web cut is only glued to the containers at certain points and not in the form of, for example, strips of adhesive or large-area gluing. This enables particularly good control of the shrinking behavior of the web blank during the shrinking process.

It is particularly preferred to apply at least one individual adhesive center per front and back of the pack on each longitudinal side edge of the web blank. Especially with transparent web cuts that may

are unprinted or only have a small motif print is sufficient

Center of adhesive on each longitudinal side edge on each front and back to prevent a larger, disturbing distortion of the web cut in the area of the front and back of the container.

According to a development of the invention, however, it is provided that at least two adhesive centers are applied to each longitudinal side edge of the web blank, spaced apart from each other on the front and back. That is, the adhesive centers are applied at a distance from one another in the direction of the longitudinal side edges. The distance between two adhesive center points on a longitudinal side edge can correspond, for example, at least to the height (in the vertical direction) of the motif print, as a result of which a particularly good pre-fixing of the printed surface section of the web blank is achieved.

In addition, further sections of the web blank can be provided with an adhesive for gluing the web blank on the end faces of the container. According to a further development of the invention it is provided that in the area of the front edge of the web blank and / or the rear edge of the web blank an adhesive is applied in order to cut the web blank with the container bottom of the container or around the front and rear edge of the

To glue the web cut together. Here too, the adhesive is preferably applied as an adhesive point. It should also be noted that in addition to particularly good control of the shrinking process by applying the adhesive as the point of adhesive, it can also be ensured that the consumer can easily open the film packaging.

According to a further development of the method, a sprayable and / or flowable adhesive is used, in particular an adhesive from the group of hard-working or hot-melt adhesives. In addition to gluing the sheet blank, this will

in particular, the opening of the container, that is, the release of the sheet blank from the containers by the consumer is further simplified.

For the particularly simple and easy implementation of the inventive method, a device described above is also particularly preferably used.

Although some aspects have been described in connection with a device, it is understood that these aspects also represent a description of the corresponding method, so that a component of the device can also be used as a corresponding method step or as a feature of a

Process step is to be understood. Similarly, aspects that are in the

Figure 1 shows schematically a device 1 for wrapping a container 2 from containers 3 (see Figure 2) with a film blank 15, here a shrink film, on which motifs 28 are printed.

The device comprises a folding and / or wrapping device 5 with a container transport device 6 and a bar element

Wrapping element 7, which moves on a path 8 around the container transport device 6 and the container 2 transported on it. Furthermore, container 2 is also to be understood as a group of containers which is only to be combined to form a container 2 with the film blank 15.

The device 1 further comprises a feed transport device 9 for feeding a pack 2 onto the pack transport device 6 and one

Discharge transport device 11 for receiving the container 2 wrapped in the film blank 15 and for further transport in a shrinking device (not shown here). The running direction LR of the container 2 is shown with an arrow. The container 2 is transported with the front 22 ahead. Part of the device 1 is also a film transport device with a first transport path T1, which leads from a film dispenser unit (not shown here) to a transport plane TE that runs from the

Container transport device 6 is formed. A second transport route T2 connects to the first transport route T1 and extends to the end of the container transport device 6.

Arranged in the vertical direction below the transport plane TE are a cutting station 12, into which the film 4 coming from the dispenser unit is inserted and in which it is cut into film cuts 15, and a first section section T1.1 of the first transport section TE. The first section section T1.1 extends from the film cutting device 12 in the conveying direction LRF of the film blank 15 in the direction of the transport plane TE. part of

Section T1.1 is a first transport device 13, which is accordingly upstream, i.e. in the conveying direction of the film blank, connects to the cutting station 12 and leads to the transport plane TE.

The cutting station 12 with the first transport device 13 and the adhesive application device 14 is offset in the horizontal direction F1 (represented by an arrow) to the container transport device 6, directly below the

Feed transport device 9 arranged.

The application of the adhesive 17 to the longitudinal side edges 29 (see FIG. 4) of the film blank 15 takes place by means of the adhesive application device 14. This has two adhesive heads (not shown here), each of which is in this way

are arranged such that it applies adhesive centers 19 spaced apart from one another on the inside 18 of the film blank 15 and here on the longitudinal side edges 29. The adhesive points 19 are applied in the end region 20 of the first transport device 13. Alternatively, for example, only one can also be used

Adhesive head (not shown here) may be arranged, for example, transversely to

Direction of delivery LRF is movable. Of course, the two adhesive heads can be arranged transversely to the conveying direction. Also, more than two adhesive heads, which are also movable or immovable, can be provided.

For wrapping the container 2, a cutting station 12 is used

Foil blank 15 produced and received by the first transport device 13, which is designed here as a vacuum table, to the container transport device 6, i.e. transported here to the transport plane TE formed by the container transport device. During transport, the film blank 15 on the

Adhesive application device 14 passed. The adhesive heads in the end region 20 of the first transport device 13 carry adhesive, here as

Adhesive centers 19, on the longitudinal side edges 29 of the film blank 15. A sprayable and / or flowable material can be used as the adhesive, in particular a hot melt or hot melt adhesive can be applied.

A container 2 brought up by the feed transport device 9 is arranged on a front edge 16 of the film blank 15. For wrapping the container 2, the wrapping element 7 designed as a rod element is immersed from below (in

Vertical direction) of the container transport device 6 between the

Container transport device 6 and the feed transport device 9 and takes the film blank 15 with it. It lies on an outer side 21. The

Envelope element 7 has a significantly higher speed than that

Container transport device 6 so that it is on the outside 21 of the

Foil cut 15 slides along and beats it around the container 2. At the end of the container transport device 6, the wrapping element 7 is immersed again vertically downward between the container transport device 6 and the discharge transport device 11, ie also below the transport plane TE. The container 2 moves onto the rear edge 30 of the film blank 15. The front 22, the rear 23 and the top and bottom 24, 25 are thus covered by the film blank 15 from the container 2. The container 2 is thus encased on four sides and has a film overhang (not shown here) over the end faces 26, on which the adhesive centers 19 are arranged. The film protrusion is then pressed onto the end faces 26 of the container 2 by a pressure element (not shown here) or a painting element (not shown here), so that the adhesive center points 19 on the end faces 26 of the container 2, ie on the corner containers 3a of the container 2 , be glued. The film 4 is then shrunk in one

Shrinking device.

Figure 2a and Figure 2b show a container 2 with individual containers 3, which is wrapped or wrapped with a film blank 15 according to the prior art. The film blank 15 has already shrunk, so that a shrinking eye 27 has formed on the end face 26. A motif 28 applied to the front 22 is shown distorted due to the shrinking process of the film material.

FIG. 3a schematically shows a first embodiment of a container 2 produced by the method and on the device with a glued film blank 15 made of shrink film in an end view. They are clearly recognizable

Adhesive centers 19 which glue the longitudinal side edges 29 to the containers 3 (here corner container 3a of the container 2) on the end faces 26 of the container 2. The adhesive points 19 were applied at a distance from one another, so that two adhesive points 19 which are arranged at a distance from one another are arranged on the respective longitudinal side edge 29 facing the front side and towards the rear side and fix the film blank 15 on the end face 26.

FIG. 3b shows the container 2 from FIG. 3a in a front view. For a better understanding of the effect of the adhesive points 19, the adhesive points 19 are also shown. However, these are located on the end face 26 of the container 2. The motif 28 points because of the glue on the end faces 26

Foil cut 15 no more distortion. FIG. 3c also schematically shows an alternative in a front view

Embodiment of the container 2, in which the film blank 15 is bonded to the front side 22 as well as to the rear side 23 on each longitudinal side edge 29 with only one adhesive point 19 on the end face 26. Here, too, the adhesive center points 19 are only for better understanding in the present

Drawn front view, but they are on the end face 26.

FIG. 4 shows schematically in a view a developed film cut 15 of a shrink film for wrapping a container 2 with marked areas for the adhesive centers 19, motifs 28 and the later position of the container 3 in the film cut 15.

The film blank 15 has two motifs 28 which are positioned in the wrapped state on the front 22 and the back 23 of the container 2. Adhesive centers 19 are placed on the two longitudinal side edges 29. There are two adhesive centers 19 for each motif 28 for each longitudinal side edge 29

intended.

The four points of adhesive 19 around a motif 28 are arranged at a uniform distance from the motif 28, which also prevents slight distortions of the motif 28.

To glue the front edge 16 of the film blank 15 to the bottom of the container 2 or the bottoms of the containers 3, two adhesive centers 19 are provided in the area of the front edge 16. Alternatively, for example, adhesive center points 19 can also be provided on the flinter edge 30 opposite the front edge 16 in order to glue the rear edge 30 to the front edge 16. The figures and the explanations above primarily show and describe the device and the method for gluing web blanks made of film (plastic, shrink film). However, it goes without saying that, alternatively, foldable paper and / or cardboard materials can also be provided, in which case a device which is largely identical in location and construction to the adhesive application device 14 can be provided for the adhesive application. The folding and / or wrapping device 5 and the elements located downstream are to be provided in an analogous manner, but for the wrapping of containers 4 with the foldable paper and / or

Carton blanks to be adapted in a known manner by a specialist.

As already mentioned, the adhesive application device 14 is ideally suited for the application of adhesives which belong to the group of diligent or

Belong to hot melt adhesive. In an embodiment, not shown, at least two adhesive heads are provided, which are arranged on opposite sides of the first transport device 13. Associated device for applying a diluent or hot melt adhesive, such as a storage container,

Meat equipment, pumps, etc. are not shown here.
