Description

The present invention relates to a method and an apparatus for forming Stückgutzzusammenstellungen, in particular container assemblies and in particular of wrapped Stückgutzzusammenstellungen. Such methods and devices have been known for a long time from the prior art.

Thus, for example, it is known that assemblies of containers, for example, containers supplied in two rows are provided with a film and this film is then shrunk to these containers. In order to achieve this, so-called shrink tunnels are provided in the prior art, through which the containers are transported. In addition, however, in the prior art, methods and devices have recently become known in which such container compositions are wrapped with a stretchable film.

So far, for example, methods for producing two-row winding packages are known, wherein a double-row bottle stream is wrapped with a film, in particular a so-called stretch film and then separated by means of a cutting device containers. A disadvantage of this approach is that usually only two-tier containers can be produced and multi-row containers are not produced, especially since the middle containers are not held by the stretch film and can slip out of the container, for example, can slide down.

In addition, the containers produced in this way are open at the sides. A completely closed container is usually not produced in this way. Advantageously, in the methods and packaging systems known in the prior art for producing such film packages, the endlessly conveyed film packages, in particular at defined locations, are severed, which can be done for example by means of a cutting device which is carried out between successive container pairs, in particular vertically through the film packages. so that each one container with four, six or eight containers is separated, which retains the desired mechanical stability in spite of the partially open end faces in two-row containers.

The present invention is therefore based on the object to provide a way with which also multi-row containers or generally larger containers can be produced. In addition, a possibility should preferably be created to produce an at least substantially and preferably completely enclosed container. It should be noted, however, that it may not be necessary to achieve both of the stated objects by the same embodiment of the invention. The solutions specified in the independent claims realize the tasks described herein.

In a method according to the invention for packaging piece goods compilations, a plurality of piece goods, in particular similar piece goods and in particular containers, are fed by means of a transport device along a predetermined transport direction. Furthermore, this plurality of piece goods is packed and / or summarized by means of a first Umwicklungselements, wherein the first development element at least partially surrounds the plurality of piece goods. Further, the plurality of packages packed with the first wrapping member are packaged with a second wrapping member, and for this, the plurality of packages packed with the first wrapping member are wrapped by a wrapping means with a wrapping member in the form of a stretchable film member, preferably wrapping around one by the transporting direction defined longitudinal axis takes place.

Packing of the piece goods compilation is understood in particular to mean that the individual packaged goods of this piece compilation are at least temporarily held together by this wrapping element.

According to the invention, the plurality of piece goods packed with the first wrapping element are fed at least one further piece goods and the assembly of the plurality of pieces packed with the first wrapping element and the at least one further piece goods is wrapped with the second wrapping element.

Advantageously, the first wrapping element is also a film element and in particular a stretchable film element. However, it would also be conceivable that the first wrapping element is a band-like wrapping element which is placed around the piece goods compilation or arranged thereon. The first wrapping element may also be a shrink film, which has been shrunk onto the containers or the piece goods in particular. In general, the wrapping elements are preferably preferably elongated, in particular ribbon-like, wrapping elements, which extend in particular in a longitudinal direction and adjacent thereto, but to a substantial extent in a transverse direction perpendicular thereto. Preferably lie these wrapping elements in a rolled-up form and can be unwound, for example, from a carrier roll. The wrapping elements are preferably elements produced from a plastic or from a paper-containing material.

It is therefore proposed in this embodiment that initially provided with a Umwicklungselement piece goods compilation is provided, this then further piece goods are supplied and then the compilation are in turn surrounded by a Umwicklungselement in the form of a film element. Advantageously, it is at the surrounded with the first Umwicklungselement piece goods compilation is a two-row container. However, it would also be conceivable that this piece goods compilation is already a three- or multi-row container. It could also be a single-row container.

In addition, it would also be possible for two or more piece goods compilations, already combined in each case with a first wrapping element, to be surrounded by the second wrapping element and thus assembled into a large pack.

Thus, the invention describes a possibility, as described above, first to produce a double-row container, for example, and to produce a stable, multi-row container by adding, for example, single-row bottle flows and repeated packaging and in particular repeated winding. In this case, as explained in more detail below, the possibility of the shrinkage package or container produced by a winding process by a predetermined angle, for example 90 °, are rotated and again with a film, such as a wrapping film wrapped, so as to produce a fully enclosed container ,

Thus, in a further inventive method for packaging Stückgutzzusammenstellungen also a plurality of cargo and in particular containers by means of a transport device along a predetermined transport direction supplied and this plurality of cargo is packed by means of a first Umwicklungselements, wherein the first Umwicklungselement surrounds the plurality of cargo at least partially and wherein the plurality of articles packed with the first wrapping element is packaged with a second wrapping element and for this purpose the wrapping device wrapped with the first wrapping element is wrapped with the stretchable film element by a wrapping device, this wrapping preferably taking place around a longitudinal axis defined by the transporting direction ,

Advantageously, the first wrapping element and the second wrapping element, which is a film element, are attached to the articles in such a way that the goods are completely enclosed by the entirety of the first film element and the second film element. This is to be understood that this inclusion is not necessarily always done by both Umwicklungselemente, but also consider either one or the other film element together considered complete all areas of the piece goods compilation. Advantageously, here too the first wrapping element may be a stretchable film or a stretch film, but it would also be possible to shrink a film, as explained above.

Advantageously, the piece goods are lying against each other or transported touching. Even with the compilation thus formed touch at least two cargo. Preferably, several piece goods each touch with their peripheral wall.

Another object of the invention is to improve the stability of such Stückgutzzusammenstellungen. Accordingly, it is proposed in a further method according to the invention for the packaging of piece goods compilations that a plurality of piece goods and in particular containers is at least partially connected to each other by means of a first connecting means, for which purpose at least two of these piece goods are fastened directly to each other.

According to the invention, this plurality of piece goods, which are at least partially connected by the connecting means, are packaged with a second connecting means in the form of a second wrapping element and for this purpose the plurality of piece goods connected by a first connecting means are transported by means of a transport device to a packaging device and conveyed through this packing device to the packaging device wrapped and / or surrounded second Umwickelungselement.

In this variant of the invention it is proposed that initially a piece goods compilation is made available in which at least two containers and preferably a plurality of containers are each connected to each other by the connecting means. In order to increase the stability of this piece goods compilation, this piece goods compilation is still with another Umwickelungs- or Enclosed element and in particular a plastic element in particular a film element surrounded.

A connection of the containers with each other is here understood in particular that not a plurality of containers is connected to each other by a common element, such as an enveloping band, but in each case a container is directly connected to another container. For example, a container can be positively connected to another element. In this case, in particular a wall of a container can be attached to a wall of another container.

Advantageously, the second wrapping element is a stretchable film element, as described above. However, instead of a stretchable film element, a wrapping tape or even a shrink film could be used.

In a further advantageous method, this wrapping with the second wrapping element takes place around a longitudinal axis defined by a transport direction. In this case, the transport direction is again the transport direction in which the containers are supplied to the above-mentioned packaging device and / or in which the containers are passed through this packaging device. The above-described aspects as well as the aspects to be described below can also be applied correspondingly to this method.

In a further advantageous embodiment, the connecting means is a flowable connecting means and in particular an adhesive. In this case, a cold adhesive or a hot (hot melt) adhesive can be used. Furthermore, it could be an acrylate adhesive. It would also be conceivable that splices are arranged on the containers at certain areas. For example, adhesive dots could be arranged on the outer surfaces of the containers. In addition, the containers could also be welded together. Advantageously, this adhesive is applied to an outer surface of the containers.

It would also be possible that the adhesive is applied to an outer wall of already filled containers. In a further advantageous embodiment, a plurality of containers and preferably also all containers are connected to one another by means of the connection means.

In a further preferred method, the connecting means holds at least two of the piece goods of the piece goods combination directly together. Advantageously, the packaging means holds together at least three of the piece goods of the piece goods compilation. It is possible that each piece goods and in particular each container connected to at least two other containers and in particular is directly connected. In addition, it would also be conceivable that some of the containers are connected to more than two other containers or generally general cargo. Advantageously, at least one, preferably several and particularly preferably each piece goods are directly connected to its nearest neighbor.

In a further preferred method, the connecting means holds together at least two piece goods disposed externally with respect to the piece goods compilation. This embodiment is based on the idea that in a wrapped piece goods compilation often the outer containers are particularly at risk of falling out.

If in this case external containers are connected to each other or to internal containers by a connecting means such as an adhesive, an all too easy falling out of these containers can be prevented. Advantageously, at least the cargo of an outer row of this piece goods compilation are connected to each other or with inner rows by the connecting means.

Advantageously, each of the pieces of goods arranged on the outside with regard to the piece goods compilation is connected by means of the connecting means to at least one further piece goods.

Advantageously, each piece goods is connected to at least two further piece goods by the connecting means. For example, it would also be possible for the piece goods to be present in several rows and for the individual piece goods to be connected to one another in each row by the connecting means.

In a further preferred method, a handle element is arranged on the piece goods compilation. In this case, it is preferably possible for a grip element to be arranged on the already wrapped piece goods assembly, in particular this grip element being arranged on a film element, for example adhered thereto. However, it would also be possible for the gripping element to be fastened directly to the piece goods and for this gripping element to be wrapped at least partially by the wrapping element. In this way, it may be possible that the film element is first removed when opening and then the handle element is accessible. However, it would also be possible for the grip element to be secured to an area of the Piece piece assembly is attached, where there is no Umwickelungselement, for example, on a plane which is perpendicular to the transport direction and the Umwickelungsrichtung.

The fact that the wrapping device is already supplied here an assembly of at least partially glued piece goods, it is advantageously possible to dispense with the otherwise to be wrapped with side guide devices, since the containers are already held together.

Likewise, it would also be possible by using an already at least partially bonded Stückgutzusammenstellung on the stationary support on which the piece goods compilation is postponed, in order to be then wrapped together with this, to dispense. Instead, it would be conceivable to push the already at least partially bonded Stückgutzusammenstellung over a gap and introduce the wrap in this gap.

By using a second wrapping, it is also possible in these embodiments to reduce the adhesive application weights and thus the amounts of adhesive compared with methods known from the prior art. Thus, it would be possible that the containers are already held together so well with a smaller amount of adhesive and / or a smaller number of adhesive dots that together with the outer wrapping a stable package comes about. In addition, the bond between the containers can also be used only to obtain a more stable intermediate product, which can be handled better in the further processing.

Advantageously, the film element is a plastic film and in particular a stretchable plastic film. This plastic film particularly preferably has a thickness which is between 3 μm and 50 μm, preferably between 5 μm and 30 μm, particularly preferably between 8 μm and 14 μm, and particularly preferably between 8 μm and 12 μm. The film element is preferably a transparent film element

Preferably, the film element is at least once completely circumferentially mounted on the Stückgutzzusammenstellung. In addition, however, it would also be conceivable that the piece goods compilation is wrapped several times with the film element.

In a further advantageous embodiment, the conveying direction is rectilinear. The piece goods may in particular be plastic bottles or glass bottles. However, it would also be conceivable to use it on other containers, such as cans or so-called pouches.

In a further advantageous embodiment, the first wrapping element and / or the second wrapping element can be arranged such that it spirally wound around the compilation.

Furthermore, it would also be conceivable within the scope of the invention to group, for example shrinkage thread or smaller winding packages and / or to stack and to wrap again. In this case, this inventive method could also be used as a substitute for so-called shrink-to-shrink method, in which the grouped and / or stacked containers are wrapped with shrink film and shrunk. Such a shrink-to-shrink process entails the risk that the film of the smaller container is glued or welded to the "collecting foil". In addition, the winding method described here is energetically favorable.

Overall, the invention allows a more energetically favorable approach and also a reduction in packaging material. In particular, a solution for unprinted low-cost containers and transport packaging can thus be created.

In a further advantageous variant of the method, a position of the piece goods being provided with the first film element or the first wrapping element is changed relative to the transport direction before the film element or the second wrapping element is attached. Advantageously, the Stückgutzzusammenstellung, in particular with respect to the transport device, rotated. Advantageously, a rotation takes place about a defined angle, for example by 90 °. Particularly preferred is a rotation with respect to an axis of rotation, which is perpendicular to the transport device and / or a transport plane in which the piece goods are transported, is.

In this way, an opening can be covered by the second Umwicklungselement, which has remained in the first winding operation with the first packaging device.

For this purpose, it would be possible, for example, that the device has a gripping device, which engages the Stückgutzzusammenstellung and rotates at a defined angle. However, such shifting and in particular turning can also take place, in order to then in a rotated position in a particularly convenient manner to add more containers to the lot configuration.

In a further advantageous method, the plurality of piece goods packed with the first wrapping element and / or the plurality of piece goods at least partially connected to the connecting element are supplied with at least two further piece goods. Thus, for example by the first wrapping element a piece goods compilation of six containers may be created and these six containers, for example, two or three more containers can be added. However, it would also be possible to add a second piece set to the first piece set. Thus, it would be possible, for example, that two piece goods compilations are formed by means of the first wrapping element, these are then brought together and surrounded by the second wrapping element and in particular the film element.

Also, combinations of the methods described herein are conceivable. Thus, for example, a piece goods compilation could initially be produced by at least partially bonding individual piece goods, these are then wrapped with a film element and this piece set compilation then at least one more piece goods are added and then the entire compilation are wrapped again. It would also be possible first to produce a piece goods compilation connected at least partially to one another by an adhesive, to add these further piece goods (in particular loosely) and then to wrap the resulting compilation.

Preferably, these are similar piece goods, such as containers that are filled with the same drink. However, it would also be possible that they are different piece goods, such as containers, which are filled with different drinks. Also, it could be piece goods of different types, such as in the case in which a group of containers are still a promotional item, such as a beverage glass or a bottle opener added.

In general, in this procedure further piece goods are supplied to the compilation, for example fed laterally. Advantageously, a supply of the other containers takes place on exactly one side wall of the first compilation. However, it would also be possible for containers to be added to the piece-goods compilation both on one and on a second (in particular opposite) side. In addition, it would be possible that this process is repeated and, for example, the piece goods compilation two containers are supplied, these are then wrapped with the film element and the resulting structure further piece goods are added.

In a further preferred method, at least two additional piece goods are aligned parallel to one another and / or the at least two further piece goods are also aligned parallel to the plurality of piece goods. It is thus possible, for example, for a large number of containers to be combined in the first piece-goods set and for each of them to be conveyed upright on a conveyor belt. This compilation can be added, for example, two other containers also standing and thus aligned in parallel.

In a further advantageous embodiment, the plurality of piece goods packed with the first wrapping element, to which another piece goods have already been added, are transported on a carrier in such a way that the at least one piece goods are in contact with the plurality of goods. Thus, it is possible, for example, that the first batch of goods is wrapped in a film and then, as it were outside the film, the other piece goods, in particular containers, are added. Advantageously, that carrier on which piece goods are wrapped is a stationary carrier. Advantageously, this carrier is wrapped by a wrapping device and then the Stückgutzzusammenstellung is pulled down or pushed down by this carrier.

In addition, side guide elements can be provided, which can also be wrapped with and from which then the Stückgutzzusammenstellung is pulled down.

In a further advantageous method, the plurality of piece goods packed with the first wrapping element and / or the plurality of piece goods, which are at least partially connected or packaged with the connecting element, are pushed onto the (in particular stationary) carrier in the transport direction. In this case, more containers can be added, for example in the transport direction behind or before the first piece set compilation, but also laterally or above. This will be explained in more detail with reference to the figures.

In another preferred method, at least a portion of the piece-goods assembly wrapped with the second wrapping element is wrapped by a further portion of that wrapped with the second wrapping element Piece lot assortment isolated. This means that in this case a piece goods compilation, in particular a continuously further transported piece goods compilation is formed with a plurality of piece goods, and these are subsequently separated again. Thus, for example, the wrapping films can be subsequently cut again and thus the piece goods compilations can be separated into any desired units. In this separation, for example, a guillotinenartiges separating element, such as knives are used, which moves in a direction perpendicular to the transport direction down direction and thus cuts at least one of the two Umwicklungselemente and in particular the film element. Preferably, this separating element is at least temporarily moved with the piece goods. In this case, this movement of the separating element can be synchronized to the movement of the piece goods.

In a further advantageous method, a plurality of piece goods is positioned such that the second film element substantially completely discharges an opening of the first wrapping element attached to the piece goods. In this case, a total of a Stückgutzzusammenstellung can be formed, which has no direct opening to the environment more. In this case, it is possible to counteract a later fouling of these piece goods compilations.

Advantageously, for example, the second wrapping element or film element can be wound transversely to the transport direction around the piece goods. Here, different transaction types are conceivable. Thus, the first batch of pieces can be a shrink pack, which is rotated, so that the openings or eyes which are systematically produced in this case are also covered.

The present invention is further directed to a piece item set comprising a plurality of parcels, wherein the parcels are at least partially in particular containers which are at least partially surrounded by a first Umwicklungselement and which are at least partially surrounded by a second Umwicklungselement, wherein at least the second Umwicklungselement is designed as a stretchable plastic film and wherein the first Umwicklungselement and the second Umwicklungselement at least partially abut each other and wherein the first Umwicklungselement abuts on at least one of the piece goods directly.

According to the invention, at least one section of the first wrapping element extends at least in sections between two piece goods and preferably separates them from one another.

In this embodiment, therefore, the first wrapping element is first applied to a first plurality of piece goods and holds them. Subsequently, further containers are added and the entirety is in turn surrounded by the second wrapping element, that is to say the film element. In this way, at least a portion of the first wrapping element is located between one of the originally wrapped containers and one of the newly added containers. Advantageously, this section of the first wrapping element forms a line and / or plane, in particular between the original piece goods and the newly added piece goods.

The present invention is further directed to a piece goods assembly comprising a plurality of piece goods and in particular containers, which are at least partially surrounded by a first Umwicklungselement and which are at least partially surrounded by a second Umwicklungselement, wherein at least the second Umwicklungselement is designed as a stretchable plastic film and wherein the first Umwicklungselement and the second Umwicklungselement abut at least partially against each other and wherein the first Umwicklungselement abuts on at least one of the piece goods directly.

According to the invention, a first geometric line extending in a radial direction of at least one first piece passes through both film elements and at least one second line extending in a radial direction of at least one second piece of goods of this piece composition only passes through a film element and / or the first wrapping element and the second wrapping element it is a film element are attached to the cargo such that the cargo is completely enclosed by the entirety of the first film element and the second film element.

Additionally or alternatively, it would also be conceivable that each geometric line always penetrates at least two Umwicklungselemente. In this embodiment, it would be possible, for example, that two piece goods compilations formed by a first wrapping element are in turn combined and surrounded by a film element. It is also possible here again that the second film element covers an opening and in this case the geometric line penetrates only one Umwicklungselement and in particular film element. In addition, it is also possible that sections of the Umwicklungselemente superimposed, so that both penetrated become. If, as mentioned, the first containers further containers are supplied, is located on these other containers only the second Umwicklungselement.

The present invention is further directed to a Stückgutzzusammenstellung with a variety of cargo and in particular containers, which are at least partially connected by means of a first connecting element (in particular with each other), said first connecting element is an adhesive, which holds together at least two piece goods this Stückgutzzusammenstellung.

According to the Stückgutzzusammenstellung is at least partially surrounded by a second Umwickelungselement and wrapped in particular. At least in part, it is understood here that the piece goods compilation does not necessarily have to be completely enveloped by the wrapping element.

It is therefore also proposed here that initially a piece goods compilation is held together with a first connecting element, in particular an adhesive, and this combination is additionally wrapped by another Umwickelungselement and in particular a film-like wrapping element. As mentioned above, it is advantageous to connect a plurality of containers or piece goods of this piece item assembly to the connecting element, in particular, and to connect them directly in particular to the connecting element.

At least in the case of the second wrapping element, it is advantageous here again to be a stretchable plastic film. In addition, however, could - as mentioned above - as Umwickelungselement also a band can be used. Advantageously, no portion of the film element in contact with the connecting means. Advantageously, the connecting means is formed only on such contact surfaces, in which contact two piece goods and in particular containers this piece goods compilation. This is in particular a basic body of the containers. Advantageously, the containers are similar containers in terms of their geometry.

Alternatively, it would also be conceivable that at least two containers are arranged one above the other in their longitudinal directions. Also in this case, the outer walls of the respective wraps can partially lie against each other.

Advantageously, the first plurality of piece goods is a double row supplied variety of piece goods. Advantageously, the entire piece goods compilation with respect to the cargo has at least one axis of symmetry.

In a further advantageous embodiment, at least one Umwicklungselement is multi-layered on at least one piece goods. Thus, it would be possible that at least one piece of goods or a piece goods compilation was wrapped several times, for example at least twice.

The present invention is further directed to a device for producing a piece-piece assembly. This device has a transport device which transports a plurality of piece goods in a predetermined transport direction. Furthermore, the device has a first packaging device, which affixes a first wrapping element to the plurality of piece goods in such a way that this first wrapping element at least partially surrounds the plurality of piece goods. Furthermore, the device has a second packaging device, which is arranged downstream of the first packaging device, in particular in the transport direction of the piece goods, and which attaches a second wrapping element in the form of a film element to the plurality of piece goods provided with the first wrapping element.

In this case, this second packaging device is suitable and determined to wrap the provided with the first film element plurality of cargo with the second film element.

According to the invention, the device has an adjustment device arranged in the transport direction between the first packaging device and the second packaging device, which device adds at least one further piece goods to the plurality of piece goods provided with the first film element. In this embodiment, in turn, it is proposed on the device side that additional containers are added between the two packaging devices of the compilation. These further containers are preferably wrapped only by the second Umwicklungselement, but not of the first Umwicklungselement.

The present invention is further directed to a device for producing a piece goods compilation, which has a transport device which transports a plurality of piece goods in a predetermined transport direction. Furthermore, the device has a first packaging device, which affixes a first wrapping element to the plurality of piece goods in such a way that this first wrapping element at least partially surrounds the plurality of piece goods. Furthermore, a second Packaging device is provided which attaches to the provided with the first Umwicklungselement variety of cargo a second Umwicklungselement in the form of a film element, said second packaging means is adapted and intended to wrap the provided with the first Umwicklungselement plurality of cargo with the second Umwicklungselement.

According to the invention, the device has an adjustment device arranged in the transport direction between the first packaging device and the second packaging device, which changes a geometric position of the first plurality of piece goods with respect to the transport device. Advantageously, this may in turn be a rotating device which rotates the piece goods compilation relative to the transport direction and in particular rotates about an axis which is perpendicular to the transport direction.

In addition, it would also be conceivable for the second packaging device to be oriented differently than the first packaging device, so that holes or opened points, which arise during the wrapping with the first wrapping element, can be closed.

The present invention is further directed to a device for producing a piece goods compilation, which has a transport device which transports a plurality of piece goods in a predetermined transport direction. Furthermore, the device has a first packaging device, which secures at least two of these packaged goods by means of a connecting element to each other. Furthermore, the device has a second packaging device, which attaches to the at least partially connected by the connecting element Stückgutzusammenstellung a second, in particular as a film element and / or belt-like Umwickelungselement, said second packaging device is preferably suitable and determined by the connecting element at least partially wrapped plurality of cargo with the second Umwickelungselement to wrap around and / or to surround.

It is thus also proposed on the device side, that initially a piece goods compilation is produced with at least one, advantageously a plurality of containers attached to each other and this is then further processed and in particular is wrapped with the other wrapping element. Advantageously, the container assembly is formed in the manner described above, i. that each outer container of this piece goods compilation is connected to at least two other containers. In this case, it is possible that the first packaging device initially attaches an adhesive to a region of the outer wall of the containers and then supplies further containers at these positions, so that, as a result, at least two containers stick together.

In a further advantageous embodiment, the device has a carrier for supporting the piece goods (in particular during a wrapping with the first wrapping element), and a removal device which removes the plurality of piece goods provided with the second wrapping element from this carrier, wherein the removal device in the Transport direction of the cargo is arranged before or after the packaging device. This removal device may, for example, be a traction unit, which optionally laterally engages a piece goods compilation and withdraws it from the said carrier. Advantageously, the said carrier is also co-wound with at least the second wrapping element. Preferably, this carrier may be formed as a sliding surface, against which the cargo can slide with a low coefficient of friction.

In a further advantageous embodiment, the transport device conveys the piece goods compilation to at least one of the two packaging devices such that at least one piece of the piece goods compilation is pushed by another piece goods of the piece goods compilation to this packaging device (and in particular pushed onto and / or opposite the carrier). This means that, for example, the foremost containers of the piece goods compilation are pushed by the subsequent ones. In particular, these said piece goods, for example containers, lie directly against one another.

Preferably, the transport device for transporting the containers may have a plurality of transport units, which transport the containers in sections, in particular in the transport direction. For example, these individual transport units can transport the containers from the first packaging device to the second packaging device.

In a further advantageous embodiment, these transport units are synchronized with one another, and at least partially convey the containers at the same transport speed.

In a further advantageous embodiment, the adjustment device has a Feeding device, which promotes the provided with the first Umwicklungselement piece goods compilation at least one more piece goods. This promotion, as mentioned above, can be perpendicular to the transport direction or obliquely or parallel to the transport direction.

The inventions described here or the inventive aspects described here are each based on the common concept that the piece goods compilation is packaged with two packaging means. In particular, at least in the outer packaging means is a stretchable film, with which the Stückgutzzusammenstellung is wrapped.

1 schematically shows a device 50 for producing a piece goods compilation 1 and more precisely a schematic plan view of a packaging machine or a section of a packaging machine. The packaging machine is used here for packaging beverage containers 10 , These are along the transport direction T as article or Stückgutstrom, here in a two-lane inlet, by means of a first horizontal conveyor 21 who are part of a total here 2 designated transport device is supplied. In this horizontal conveyor 21 it may be, for example, a conveyor belt, a mat chain conveyor or the like.

The reference number 52 denotes a first packaging means in the form of a wrapping means, ie a winding module, in which the containers are wrapped with at least one layer of a stretch web foil, a so-called stretch film. In this case, this first packaging device 52 have a circumferential role or a rotating film dispenser, which rotates here in a circular path perpendicular to the plane of the figure around the containers. Unlike in the 1 However, the two rows of containers are shown 10 also brought together, so that they are ultimately supported adjacent to each other and wrapped.

The stretch film is in a conventional manner helically around the pairs side by side conveyed article or beverage containers 10 wound, wherein preferably provides sufficient tension of the film for the firm mechanical cohesion of the article or piece stream.

For the trouble-free transport of the article or piece stream in the first packaging device 52 To ensure, for example, circumferential feed belts (not shown) laterally attack the article or cargo flow, which the containers 10 through the first packaging device 52 promotes while the containers 10 be wrapped at the same time. It is conceivable that an operating speed of the first packaging device and / or the second packaging device is synchronized with a transport speed of the piece goods at least temporarily and preferably constantly.

In the first winding module 52 The containers are usually slide on a lower support or a sliding plate, which is also wrapped. In the further course of delivery, however, the already wrapped article or Stückgutstrom is drawn over the slide plate, wherein the stretch film applies after leaving this slide plate due to their bias to the bottom of the containers.

The reference number 61 indicates a first feed module, which causes the further transport of here now already wrapped with a layer of film element article and Stückgutstroms. This feed unit may have, for example, upper and under feed belts or feed belts, which preferably over the length of this first feed module 61 attack endlessly on the upper and lower sides of the article or piece goods flow and thus ensure further transport. Again, lateral guides can be provided again, which support the left and right the article or Stückgutstrom and lead laterally.

The reference number 60 Characterized roughly schematically a matching device, which is designed here as a feeder, which adds further piece goods to the already bundled with the first Umwicklungselement piece goods compilation. This feeder can have a transport device which feeds these further products laterally. It is conceivable that a conveying speed of this further feeding device with a transport speed of the transport device, which the containers through the packaging devices 52 . 54 promotes, is synchronized.

In this way, defined piece goods can be added to each of the packaged goods wrapped with the first wrapping element. In a further advantageous embodiment, this adjustment device 60 also have a delivery device (not shown), which bring the other piece goods so close to the wrapped with the first Umwicklungselement piece goods that they contact these and / or the first Umwicklungselement. In this way, can be wrapped again by the subsequent second packaging device very tight-fitting Stückgutzzusammenstellungen.

In addition, an adaptation device (not shown) may also be provided for this region, which rotates the piece goods compilations, for example by a defined angle of 90 ° with respect to an axis which is perpendicular to the plane of the figure.

The reference number 54 denotes a second packaging device, again in the form of a wrapping device, ie a wrapping mode, which in turn winds a second layer of stretch film in a helical manner around the article or piece goods stream. Advantageous here is a winding angle relative to the winding angle of the first wrapping station 52 changed.

The reference number 62 denotes a second feed module, which causes the further transport of the now bundled with several layers of stretch film unit load. For this purpose, in turn, upper and lower feed belts or feed belts may be provided, which preferably over the length of the second feed module 62 circulating endlessly on the upper and lower sides of the article or Stückgutstroms and for its further transport to the subsequent second horizontal conveyor 73 to care. In the area of this conveyor 73 and 75 cutting elements can be provided which cut the winding film. These cutting elements can move along with the containers at least during a cutting process.

The reference number 66 indicates a Abtransporteinrichtung which the now cut containers or piece goods compilations 1 removed.

1a shows a side view of an apparatus for producing such Stückgutzzusammenstellungen. Again, you can see the transport again 2 , which containers 10 initially on a stationary carrier plate 32 pushes. This means that the containers by pressure on the carrier 32 be pushed. The reference number 34 characterizes lateral guide elements, which cause the containers 10 be wrapped tightly together. In the first packaging device 52 become the containers 10 wrapped so, including the support plate 32 and the side guide element 34 to be wrapped up with.

The reference number 36 indicates further transport facilities, which now transport wrapped containers, that is in 1a to the right. In this way, the Stückgutzzusammenstellungen are also back from the carrier 32 and also from the side guide elements 34 deducted.

The reference number 68 indicates a first cutting element, which cuts off each Stückgutzzusammenstellungen. This can, as shown by the arrow P1, be arranged guillotinenartig in a vertical direction. The piece goods compilations produced in this way are converted into a further wrapping device 54 transported and can also be wrapped there again with a stretch film. The reference numerals 72 and 74 here identify transport facilities, which ensure a feed of the piece goods. Between the first winding module and the second winding module, the Stückgutzzusammenstellungen, as mentioned above, are rotated, but in 1a about an axis of rotation, which runs in the plane of the figure.

The reference number 68 indicates a further cutting element, which in turn serves to cut off the stretch film. About a conveyor belt 82 The pieces of goods thus completed can be transported away.

2 shows a rough schematic representation to illustrate the production of Stückgutzzusammenstellungen. Ultimately, it is possible, as explained in more detail below, a variety of containers 10 first tie together into a group and then with a wrapping element 12 , as here to wrap a film. In the following steps, the processing is from a single container 10 to a container bundle, which takes place through several wraps shown.

3 explains a general manufacturing process. In this case, initially a plurality of containers, already from a first Umwicklungselement 12 are surrounded, supplied. The reference number 13 indicates an opening that can occur, for example, during a shrinking process. This first compilation of containers 10 will be two more containers 10 (second partial picture in 3 ) added. With the second wrapping device (not shown) becomes a film element 14 attached to this compilation of the first piece set and the two other containers. This film contracts so that (right part of the picture) a container of six containers is created in the end. This is now a completely wrapped container.

In this case, the film element lies directly on some of the containers 12 (and on this also the film element 14 ), here on the containers on the left side and on some of the containers only the film element 14 , here at the containers on the right side. In some areas, eg here at the middle containers are both film elements.

4 indicates a first step for a corresponding manufacturing process. Here, four containers or general containers are juxtaposed as an example and wrapped by a first wrapping element, here also a stretch film. Such a wrapped or shrunk container is, as shown in the next drawing, produced, here systematically a film eye 13 arises, as shown in the right part of the picture.

This container can now, as in 5 shown, further processed. As in the 5 shown representation are brought to the container shown in the left part of the figure below two more containers and the entire compilation is, as shown in the second field from the right, wrapped again. The stretch film in turn lays down (see right drawing) so that a completely wrapped container with six containers is formed.

In 5a another process is illustrated. Here are the in 5 (right-hand part) shown container two more containers and this compilation is wrapped again. Thus arises (see right partial picture of 5a ) in the result a container of eight containers, which, however, was wrapped here by three foil elements. You can also see the section here 12a the first Umwicklungselements, here film element which extends between containers. The in 5a The process shown could still be continued and, in particular, successively more general cargo could be added to an already existing batch of goods. Accordingly, the reference numeral refers 15 to another film element, which in addition to the film elements 12 and 14 wrapped the piece goods assortment.

The reference L1 denotes a geometric radial line which starts from one of the containers and penetrates both wrapping elements. The reference character L2 designates a further geometric radial line, which starts from a further one of the containers and which penetrates only one of the two wrapping elements.

6 shows a similar representation as 5 , with the difference, however, that here two containers are added above the compilation of the four containers and wrapped in total. According also shows 6a a similar representation as 5a , whereby also here more containers are added above.

At the in 7 In the situation shown above, two bottles are added both above and below the container shown in the left-hand part of the picture, and the entire container is wrapped again. The right-hand representation shows a container which is composed of two film elements, namely an inner film element 12 which surrounds four containers and an outer film element 14 , which surrounds all containers.

7a shows a representation in which the in 7 resulting piece goods compilation both above and below (ie from two sides ago) further general cargo be added. This entire compilation is again wrapped with a foil element and so creates a large container with here total 12 Containers. It is thus proposed that the process according to the invention of adding containers to an already wrapped piece goods compilation can also be repeated several times.

7b shows a further illustration of a method according to the invention. Here, first two shrunken containers are moved together and these two shrunken containers are then wrapped with a foil. In this way, a container which contains two shrinkage packages, which are each surrounded by the second film element as a wrapping film, is produced (compare right-hand part of the drawing).

7c shows a similar representation as 7b However, four such Shrinkage bundles are wound together and in this way (lower part of the figure), a wrapped container of four shrinkage packages is formed.

8th illustrates another compilation, wherein the number of containers here can be at least two pieces or more. The above-mentioned containers are, as mentioned above, by wrapping with foil to large packages.

9 illustrates another collection of containers, here two shrinkage packages are superimposed and also wrapped again with a film.

10 shows that even an arrangement of several shrinkage packages can be combined on top of each other with a lateral arrangement, so that the in 10 shown large container arises.

The 11 to 23 illustrate the production of containers without openings or eyes. 11 illustrates this in principle how individual containers 10 can be put together to open-closed container containers. It is initially possible, as in 12 shown to produce a container having an opening or a foil eye. This container can then be rotated in front of the second wrapping unit, about 90 °, and then wrapped again. Through this second wrapping is also the film eye 13 closed, so that the container is completely closed, as in the right part of 12a shown.

In 13 The production of such a container is also illustrated. Again, containers are placed next to each other and taken for example in the second field with foil. In the third upper part of the picture, this results in a shrunken or wound container with a foil eye 13 , This container is now, as shown in the next figure, rotated by 90 °, and wrapped again. Finally (see the last drawing) a wrapped container is created, which is completely closed.

14 shows a combination of the methods presented so far. The starting point here again is a wrapped container containing six containers and two foil elements 12 . 14 , This is rotated by 90 ° and wrapped again with a film. Again, a container of six containers, but which is completely closed. This manufacturing process can be used for any type of wrapped containers application.

15 indicates another possible manufacturing process. Again, a wrapped container is again generated and then a winding film is wound transversely to the machine direction. Here, too, arises (last field of 15 ) a wrapped container, which is completely closed.

16 shows a further illustration of a procedure described. Again, the starting point is again a wrapped container, which is also wrapped here again with a winding film transverse to the machine direction. Also in this case, again a wrapped container, which is completely closed. This manufacturing process can be used for any type of wrapped containers.

At the in 17 shown embodiment, two shrunken container or wound containers are initially provided and juxtaposed. Then they are wrapped in foil, as shown in the last upper part of the picture. This results in a wrapped container (lower part figure left), which is again rotated by 90 ° (second lower subpicture of 17 ) and wrapped with a second film. Again, this creates a wrapped container, which is completely closed and which may have two shrink-wrapped or wrapped inside, for example.

18 resembles the in 17 shown illustration, but here there is no rotation of the container by 90 °, but a second winding transverse to the machine direction. As a result, a wrapped container is formed here, which is completely closed.

19 again illustrates the manufacture of containers which are completely enclosed.

At the in 20 shown or more shrunken or wound containers stacked on top of each other and in turn wrapped with a film. Again, there is again a wrapped container, which, however, has a foil eye. These containers will, as in 21 shown rotated by 90 ° and wrapped again with foil, so that the result is a wrapped container, which is completely closed.

The 22a and 22b illustrate in a similar manner, in turn, the production of a wound container, in which case again no rotation of the container is made, but the second winding film is again applied transversely to the machine direction. Again, it should be noted that the shrunken container is first supplied in such a way that, for example, a film eye is forward and so can be wrapped by the second wrapping film.

23 Finally, illustrates the production of large containers from a plurality of superimposed containers.

24 shows a further embodiment of a piece goods compilation. This has here 6 containers, each with each other by means of connecting means 42 are connected. These connecting means may in particular be adhesions. During production, splices can be selectively applied to the peripheral walls of individual containers, and additional containers can be applied to them 10 be glued. In this way, the containers are not packaged by a surrounding Umwicklungselement here, but each held in pairs in particular. In this way it is already possible to achieve a relatively stable composition. Strictly speaking, this is a variety of connecting means, which preferably hold the containers together in pairs

At the in 25a As shown, this piece goods compilation is now of the second wrapping element 14 wrapped. It should be noted that these representations are with the wrapping element 14 strictly speaking, this is the only wrapping element. However, the concept of the second wrapping element has been retained for the benefit of consistent terminology. This wrapping element 14 surrounds the piece goods collection position here with respect to an axis that runs horizontally. The transport direction along which the piece goods are transported also runs horizontally here. Through the wrapping element 14 Nevertheless, a higher stability of the wrapped piece goods compilation can be achieved.

25b shows a further illustration of a Stückgutzzusammenstellung. It can be seen here that a connecting element (arrow P2) between the two middle containers was dispensed with. This is possible while maintaining sufficient stability, as this stability still by the surrounding Umwicklungselement 14 is reached.

At the in 25c shown representation has been dispensed with multiple splices or fasteners. More precisely, here the upper row of piece goods is not glued to the lower row of piece goods. Again, this is still acceptable because of the additional wrap around the desired stability. At the In 25d Finally, no connection points or connecting elements were mounted between each laterally adjacent container pairs.

It can be seen that in addition to the embodiments shown, other combinations are possible. Also several containers could be put together as shown. In addition, could also in the 25a -D shown piece goods compilations still more containers are added and such a compilation are wrapped again.

In addition, could also in 25a -D shown piece goods compilations are wrapped again with a further wrapping device, so as to again obtain completely closed Stückgutzzusammenstellungen. In addition to the in the 25a -D shown piece goods compilations also handle elements are attached.
