EP3166779B1 - Stack formed of bags - Google Patents

Description

The invention relates to a method for producing at least one stack formed from bags according to claim 1, a stack formed from bags according to claim 7,

It is known to produce bags, in particular plastic bags (such as waste bags, freezer bags or the like), and to wind them up coherently on a roll. A predetermined number of such bags are then on a roll. A user then separates the bags one after the other as required so that they can be used for their intended purpose. This separation occurs, for example, in that the bags that were previously connected to one another on the roll via a perforation or welding are torn off by the user along this perforation.

From the DE 82 05 209 U1 a dispenser for plastic film bags from the roll is known, which consists of a tubular film, preferably provided with folds on its two long sides, which has transverse tear-off perforations with at least a partial average and in the vicinity of the same, in the pull-off direction in front of these, also transverse welded bags - Has bottom seams, the dispenser having the shape of an approximately cylindrical sleeve with a removal slot for the tubular film running in its longitudinal direction, with the edge of the removal slot overflowing from the tubular film when it is pulled out of the sleeve in the area of each partial cut in the tear-off perforation of the tubular film is one that protrudes beyond this edge in the circumferential direction of the sleeve, that is, protrudes into the removal slot or almost completely bridging tongue is provided which is approximately rectangular in its basic shape, the width of which in the longitudinal direction of the sleeve is equal to or only slightly smaller than the width of the associated partial average in the tear-off perforation of the tubular film.

This way of producing and providing bags has proven successful. However, there is the disadvantage that, on the one hand, the user perceives it as an undesirable process to have to separate the bags connected to one another via the perforation for the respective purpose. In addition, from a logistical point of view, the shape of a roll represents disadvantages. With the roll, the available packaging space cannot be optimally utilized either in storage or in presentation for sale. In addition, it is very time-consuming to provide such a roll with information about the type and nature of the bags that are on the roll.

DE 25 51 569 A1 relates to a method for producing stacks of folded bags from a tubular or semi-tubular web which is provided with transverse welds to form the bags and from which the subsequently stacked bags are separated. D1 thus discloses the preamble of claim 1.

The invention is therefore based on the object of providing a method for producing at least one stack formed from bags, a stack formed from bags.

This task is solved by the independent patent claims.

1. a) Zuführung von schlauchförmigen oder halbschlauchförmigen Material zur Ausbildung einer unteren Materiallage und einer oberen Materiallage,
2. b) Einbringen mindestens einer Schweißnaht zur Verbindung der unteren Materiallage und der oberen Materiallage zur Bildung einzelner, jedoch noch zusammenhängender Beutel,
3. c) Einbringen einer Formatierungsfaltung in die aus noch zusammenhängenden Beuteln gebildete Lagenbahn,
4. d) Separation der in der formatierten Lagenbahn zusammenhängenden Beutel zu einzelnen Beutel, wobei diese Beutel weiterhin die Formatierungsfaltung aufweisen,
5. e) Bildung eines Stapels aus einzelnen Beuteln,
6. f) Einbringen mindestens einer Faltung in den Stapel.

According to the invention, a method for producing at least one stack formed from bags is provided, comprising the following steps:

1. a) feeding tubular or semi-tubular material to form a lower material layer and an upper material layer,
2. b) introducing at least one weld seam to connect the lower material layer and the upper material layer to form individual but still coherent bags,
3. c) introducing a formatting fold into the layer web formed from still connected bags,
4. d) separating the bags connected in the formatted layer web into individual bags, these bags continuing to have the formatting fold,
5. e) forming a stack of individual bags,
6. f) introducing at least one fold into the stack.

The method listed above enables the continuous production of individual bags to form at least one folded stack that has an angular geometry (for example cuboid shape). These stacks are suitable for inclusion in a container, for example a dispenser box. For this purpose, the container also has an angular geometry, which in the interior area approximately corresponds to the geometry of the at least one stack to be accommodated there. The user can remove each bag individually from the stack with little effort. The bags can also no longer be damaged or even destroyed when separated by the user. Each bag is made available to the user in consistent quality. The combination of the formatting fold of the respective bag with the folding of the stack ensures that after a bag has been removed from the stack, another bag is always made available for removal from the stack and a compact stack is realized that optimally uses the space within the container exploited. Due to the angular geometry, containers such as dispenser boxes can be stored very well (by making optimal use of the available storage space) and presented attractively for sale (since, compared to rolls, large areas of the angular container are available for information for consumers and/or product information) . When a bag is removed, the user can also be provided with closures to securely close the bags. A continuous process is therefore provided from the production of the bags to the formation of stacks. Packaging, i.e. collecting individual bags to form an overall package or stack, takes place for a variable but defined number of bags. The layered web is formed from at least two layers of material.

The process can be carried out continuously if, for example, web-shaped, semi-tubular or tubular material is continuously produced by extrusion. The process can be carried out batchwise or discontinuously if the web, semi-tubular or tubular material is made available, for example, on rolls. It is also conceivable to combine the materials supplied on rolls with the material of the next roll before one roll is used up in order to obtain a quasi-continuous process. Batch processes are processes that are processed as a 'batch', i.e. strictly one after the other. Therefore, batch processes are also known as batch processing. In terms of the process, material on rolls is fed into the process one after the other. The batch process or batch process or set operation is a discontinuous production process. A limited amount of material, for example a roll, is fed into the process as a whole and removed from it as a whole after the production process has been completed, in this process, for example, as a stack formed from bags.

A fold can be hard in the sense of a fold or with a curve. Any configuration of folding between these extremes is also possible. A fold is created in the process by means that cause the direction of the material to reverse. At least one fold, for example to form a material tube or material half-tube, can also have been introduced into the material before the process.

Semi-tubular material refers to material that has undergone a reversal of direction to form a lower and an upper layer of material. This reversal of direction can also be viewed as a folding. Semi-tubular material can be fed to the process or produced in situ from web-shaped material in the process. Semi-tubular material can also be made by forming a cohesive seam in the longitudinal direction from two layers of web-shaped material before being fed to the method according to the invention or during the implementation of the The method according to the invention can be generated. The cohesive seam is created, for example, by gluing or welding.

Tubular material is material that is self-contained and is produced, for example, by extrusion or has a longitudinal connection point. This connection point can be made cohesively, for example by gluing or welding. If tubular material is exposed to pressure between two flat surfaces, a lower layer of material and an upper layer of material are formed. In the transition area between these two material layers, the material undergoes a reversal of direction, which can also be seen as a fold.

Furthermore, it is provided according to the invention that the stack is provided with a safety device to prevent the stack from accidentally falling apart. This securing can be done, for example, by a flexible, flexible element such as a wire, a band or the like. Securing can also be done by surrounding the stack with shrink wrap. Alternatively, securing can be done by wrapping the stack with paper, for example in the form of a band. Safety measures such as adding more mass to the stack are also covered by the idea of safety. To secure the individual bags of a stack, the individual bags of a stack can also be provided with adhesive points in order to attach the individual bags of the stack to one another, whereby this security should be designed to be easily overcome for use of the individual bags. The security can also secure the transport of the stacks, for example from the production of the stacks to the packaging of the stacks. This ensures that the arrangement of the bags within the stack does not change during transport. The stacks provided with security can also be stored in order to receive outer packaging later or to leave the storage location without further packaging measures. The stacks provided with the security described above can be supplied for storage or transport as well as for sale, although it is alternatively also conceivable to supply the stacks provided with the security in this way to the container. However, it should be taken into account that the backup may have to be removed if individual bags are to be removed from the container and thus from the stack.

Furthermore, according to the invention it is provided that the stack is transferred to a dispenser box. The previously listed process allows for the continuous manufacture of individual bags and the collection of bags to form a stack for inclusion in a dispenser box. The formatting folding of the individual bags and the subsequent folding, for example carried out as a Z-fold or U-fold, to form the stack makes it possible to remove each individual bag from the removal opening of the dispenser box. The user can remove each bag individually from the dispenser box with little effort. The bags can also no longer be damaged or even destroyed when separated by the user. Each bag is made available to the user in consistent quality. The combination of the formatting fold with a further fold, for example the Z or U fold, advantageously ensures that after a bag has been removed, another bag is always made available for removal. This occurs from the first to the last removal of bags from the dispenser box. When a bag is removed, the user can also be provided with closures to securely close the bags. A continuous process is provided from the production of the bags to their packaging in dispenser boxes. The stacks that have been secured can also be transferred to a dispenser box. This makes the stacks easier to handle and prevents the stacks from falling apart before they get into the dispenser box. The security can then be removed immediately after the stacks have been transferred to the dispenser box or can be removed the first time the user accesses the contents of the dispenser box. This ensures that the stacks do not change shape during transport.

Furthermore, according to the invention it is provided that the weld seam is carried out with exact repeatability based on markings. The precise execution of at least one weld seam enables bags with identical or almost identical dimensions. The user thus receives bags of the same volume. The markings, for example one marking or several markings per bag, can also help the user to always achieve the same fill levels in the bags. If the material fed into the process has regular imprints, it is ensured that each bag is provided with the appropriate imprint.

Furthermore, it is provided according to the invention that the at least one fold introduced into the stack is carried out as a Z-fold, a W-fold, an accordion-like fold or a U-fold. The at least one fold of the stack, which already has a formatting fold for each bag, is characterized by a change in direction of the entire bag forming the stack. For example, a U-fold results in one such change in direction and a Z-fold results in two such changes in direction. More than two changes of direction (folds) are also conceivable, for example a W-fold or an accordion-shaped sequence of folds. This makes it possible to adapt the stack individually to the format of the dispenser box and thus increase the packing density. A dispenser box can also hold one or more stacks folded in this way. These stacks can, for example, be aligned parallel to one another, transversely to one another or alternatively parallel and transversely to one another. The formation of various angles between the individual stacks is also conceivable.

Furthermore, it is provided according to the invention that the formatting fold is introduced into the layer web in such a way that the width of the layer web after the formatting fold has been introduced corresponds at least to the inner dimension of an edge length of the dispenser box. This means that a measurement of the dispenser box is transferred to the bag as part of the process. This ensures that the stack formed from these bags can be inserted into the dispenser box. The size can be varied according to the dispenser box used.

According to the invention, a bag is provided having a lower material layer and an upper material layer connected by at least one weld seam, the bag having at least one opening arranged at right angles or almost at right angles to the at least one weld seam. If the bags are arranged at right angles or almost at right angles to the weld seam and have at least one opening, this opening is opposite a fold.

According to the invention, a bag is provided which has a lower material layer and an upper material layer, connected by at least one weld seam, the bag having at least one fold arranged at right angles or almost at right angles to the at least one weld seam. The at least one fold arranged at right angles or almost at right angles to the weld seam can be opposite another fold or an opening. If there is an opening opposite the at least one fold, the web of material fed to the process consists of a half-tube. If the at least one fold is opposite another fold, the web of material fed to the process consists of a tube.

Furthermore, it is provided according to the invention that the at least one weld seam forms a bottom seam or a side seam of the separated bag. If the weld seam forms a bottom seam, the web was fed into the process as a hose. If the web of material is supplied as a half-tube, the at least one weld seam forms a side seam of the later bag.

Furthermore, it is provided according to the invention that, if the at least one weld seam forms a bottom seam of the bag, an opening is formed opposite it. In this case, the web was fed into the process as a tube. A separating cut or a separating weld is carried out opposite the weld seam, which runs transversely to the processing direction of the material web, at a distance corresponding to an edge length of the bag, so that the bag resulting from a tubular web of material has only one weld seam. However, he has two Folds made at right angles or almost at right angles to this weld seam. This design enables the production of a bag with just one weld.

Furthermore, according to the invention it is provided that the bag is formed as a bottom seam bag with a weld seam. To form a bottom seam bag, the web is fed into the process as a hose. Just one weld seam is enough to create a bag that is closed on three sides. An opening is provided for filling the bag. After the bag has been filled, it can be closed materially, for example by welding. A rubber band or a clip is also conceivable.

Alternatively, the invention provides that the bag is formed as a side seam bag with two weld seams. Here, a half-tube is fed into the process as a web of material. The bag, which is closed on three sides after going through the process, has a bottom created by folding and two weld seams arranged at right angles or almost at right angles to the bottom as sides. An opening that has already been created by folding the web into a half-tube remains. The bag, designed as a side seam bag, can be filled through this opening. After the bag has been filled, this bag can also be closed materially, for example by welding. A rubber band or a clip is also conceivable.

Furthermore, it is provided according to the invention that the bag has at least one marking for precise processing. These recurring markings enable work steps to be carried out at always the same intervals, carried out in the direction of travel of the web. For example, this ensures that prints, especially advertising prints, are always positioned the same way in relation to the individual bag. This means that printing can already be carried out on the continuous web of material. All bags separated later have an identical appearance. These markings can help the user to create equal filling levels of goods in several bags of the same type. For example, the markings are provided with volume information.

According to the invention, a stack formed from bags is provided, having at least one weld seam and at least one fold, this stack being produced using a method according to the steps described above. This stack is designed to be placed in a dispenser box in order to remove bags individually from it. This provides a high level of comfort for the user, as he can always remove the individual bags from the dispenser box with the same little or almost the same amount of effort. In terms of feel, removing the bags is a positive experience for the user, as they do not have to use any force to separate the bags.

According to the invention, it is intended to accommodate a stack according to claim 7 in a donation box.

The dispenser box is angular in shape, for example cuboid, but also pyramid-shaped or the like, so that it can be easily stacked. Their surfaces can also be printed easily and representatively. For example, printed brands, logos, product information, warnings, price tags, advertising information and the like are better displayed.

The dispenser box can have at least one removal opening, which can be closed until a bag is removed for the first time. For example, a perforation can be provided to remove the closure element, with the course of the perforation reflecting the later size and shape of the removal opening. A separate closure element can also be provided, which closes the removal opening until a bag is removed for the first time. Measures such as seals can be provided here, which ensure that the guaranteed number of bags per packaging unit is available to the user after purchasing the dispenser box with folded bags.

The dispenser box is preferably filled with at least one stack consisting of a defined number of bags. These bags have a formatting fold and, for example, a Z-fold or a U-fold. After both folding processes have been carried out, the stacks of bags are almost the same size as the inside dimensions of the dispenser box. This ensures, on the one hand, that the volume of the dispenser box is almost exhausted and, on the other hand, that the individual bags can be easily removed. The bags are removed piece by piece from the outside to the inside. The user can remove each bag individually, regardless of how the stack is folded. The dispenser box can, for example, be made of cardboard, metal, plastic or composite materials.

For easy removal, in particular the bag facing the removal opening can be fixed to the closure element for the removal opening. This fixation is preferably designed so that the bag can be easily detached from the closure element after removal so that it can be put to use. To fix the bag on the side of the closure element facing the bag in the closed state, for example, an adhesive point can be provided. It is also conceivable to link the individual bags in the stack using, for example, adhesive dots, so that the bag following the removed bag is always kept in or near the removal opening. If several stacks have been placed in a dispenser box, a connection between the stacks is also conceivable so that the bags forming the respective stack can be easily removed.

An auxiliary element such as an adhesive strip can also be attached to the bag of a stack intended for the first removal in order to form a type of handle. This auxiliary element makes it easier for the user to remove the first bag. Additional bags can also be provided with auxiliary elements to make it easier to remove them from the dispenser box. The at least one removal opening can also be provided on the underside of the dispenser box so that gravity supports the removal of the individual bags. For this purpose, the dispenser box is preferably arranged elevated so that the user has easy access to the removal opening arranged on the underside. In support of the Due to the effect caused by gravity, a mass piece can also be provided, which is arranged above the stack or the bags in the dispenser box. A curved, spring-like element can also be provided opposite the removal opening in the dispenser box, which exerts pressure on the stack or the bags in the direction of the removal opening. This ensures that the bag intended for the next removal is always arranged in the area of the removal opening.

The bag can be made of various materials, for example plastic films. The use of thin metal foils is also conceivable. Web-shaped, semi-tubular, or tubular knitted fabrics, nonwovens or the like can be used in the process. Ultimately, all web-shaped, semi-tubular, or tubular materials that can be cohesively connected can be used and are suitable for forming bags. Stacks can then be created from these bags for placement in dispenser boxes, for example.

It is envisaged that any design of bags, in particular plastic bags, will initially be made available in an endless web. This endless web is then folded at least once symmetrically to the longitudinal axis or asymmetrically to the endless web provided, so that partial areas, possibly complete regions of the endless bag web then overlap or even lie on top of each other.

In a subsequent step, the individual bags that had previously been connected to one another are separated from each other at predetermined points from the folded endless web. This can be done in a manner known per se by a cutting process or processes with the same effect. These individual bags folded in this way and separated from the endless web are placed on top of each other to form a package or folded further. This is done in a specified number of pieces. The number of pieces depends in particular on the volume of the dispenser box in which the folded and stacked bags are to be placed. At this point it is conceivable to fold each individual bag parallel, crosswise or at least once again in order to achieve this The format of the then folded bag must be adapted to the receiving space of the dispenser box.

A dispenser box is then made available in which a stack of folded bags in a specified number is placed in the dispenser box. This can then be delivered and put to use.

The at least one fold before the individual bags are separated from the endless web is carried out in such a way that a predetermined number of bags are available in a stack after the separation. If this stack is placed in the dispenser box, it is possible to remove individual bags from this dispenser box. An additional separation of these bags when removing them from the dispenser box is advantageously eliminated.

In addition to the at least one fold before separation, it is conceivable to fold the individual separated bag at least once again and/or to fold the bags of a certain number placed on the stack at least once again. These further folds have the advantage that the dimensions of the respective bag (length, width) are changed again, in particular reduced, and thus not only the storage space of the dispenser box can be better utilized, but also the format of the stack of folded bags can match the format of the Dispenser box can be customized.

As a rule, the bags have a format with a square (long side = wide side) or rectangular dimension. Accordingly, it is also an advantage if the dispenser box has square or rectangular dimensions. However, it can also be considered that the dispenser box has a triangular format, for example, and the bag separated from the endless web is folded at least once in such a way that it assumes the corresponding triangular shape of the dispenser box for storage in the dispenser box in a stack.

It is important that the bags are folded so that they can be individually stacked and placed in the square-shaped dispenser box. The square format of the dispenser box has the main advantage that the available space is optimally used during transport and later offering (e.g. on the shelf in the supermarket). Such a square dispenser box also offers the significant advantage that it can easily be provided with product information in a manner known per se.

An exemplary embodiment of the invention is explained in more detail below with reference to the accompanying figures.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the device and other elements selected in the respective figures. These terms are not to be understood as restrictive, i.e. these references can change due to different positions and/or mirror-symmetrical designs or the like.

The same elements are given the same reference numbers in all figures and the following description.

It is envisaged that any design of bags 1, in particular foil bags, will initially be made available in an endless web of goods. This endless web of goods is then folded at least once symmetrically to the longitudinal axis or asymmetrically to the endless web of goods provided, so that partial areas, possibly complete areas, of the endless bag web overlap or even lie on top of each other.

The Figures 1A and 1B show two connected bags 1, formed from a half-tube with a lower material layer 2 and an upper material layer 3. At the point of separation between the two bags 1 there is at least one weld seam 4 for connecting the material layers 2, 3. One at right angles or almost at right angles to the Weld seam 4 arranged side of the bag 1 is formed by a fold 5. The side of the bag 1 opposite the fold 5 has an opening 6. Markings 7 are placed at regular intervals near the side of the bag with the opening 6. These markings are used to process the bags 1 with repeat accuracy. These markings 7 make it possible, for example, to place the weld seam 4 with repeat accuracy. If, for example, prints, in particular advertising prints, are attached to the bags 1, they can always be precisely positioned for the individual bag 1 by welding.

The Figure 1B shows schematically a section through a bag according to Figure 1A outside the weld seam 4 and parallel to the weld seam 4. The opening 6, which is opposite the fold 5, can be clearly seen. The fold 5 is to be seen as a reversal of direction for the material forming the bag 1. It can be hard in the sense of a fold and with a curve.

Different from the Figures 1A and 1B show the Figures 2A and 2B two connected bags 1, formed from a tube with a lower material layer 2 and an upper material layer 3. There is a fold 5 opposite each other at right angles or almost at right angles to the weld seam 4.

The Figure 2B shows schematically a section through a bag according to Figure 2A outside the weld seam 4 and parallel to the weld seam 4. It can be clearly seen that two folds 5 lie opposite each other.

The Figures 3A, 3B , 4A and 4B show a formatting fold 8 in the web of connected bags 1. The Figures 3A and 3B show coherent bags 1 with an opening 6 according to Figures 1A and 1B . The Figure 3B shows schematically a sectional view according to Figure 3A in the area outside the weld seam 4, but parallel to the weld seam 4. The opening 6 can be clearly seen.

The Figures 4A and 4B show connected bags 1 according to Figures 2A and 2B . The Figure 4B shows schematically a sectional view according to Figure 4A in the area outside the weld seam 4, but parallel to the weld seam 4. Two opposite folds 5, before the formatting fold 8 is introduced, can be clearly seen.

The Figure 5 shows a separated bag 1, which has a fold 5 and an opening 6 according to Figures 1A, 1B , 3A and 3B or two folds 5 according to Figures 2A, 2B , 4a and 4B can have.

The bags 1 are separated from the web of material, for example by cutting or separation welding. For bags 1 according to Figures 1A, 1B , 3A and 3B An opening can be provided opposite a weld seam 4.

The Figure 6 shows a package formation by collecting individual bags 1 to form a stack 9. This stack 9 is continuously formed from individual bags 1.

The Figure 7A shows a top view of a stack 9 according to Figure 6 .

The Figures 7B and 7C show variants for further folding a stack 9.

The Figure 7B shows a Z-fold 10 and the Figure 7C shows a U-fold 11. The stacks 9 of bags 1 designed as a Z-fold 10 or as a U-fold 11 are placed in a dispenser box 12 according to Figure 8 transferred. The bags 1 can easily be removed individually from this dispenser box 12 through the at least one removal opening 13. Due to the folding, in particular U-folding 11 or Z-folding 10, a bag 1 is always within reach for the user in the area of at least one removal opening 13. When a bag 1 is removed, this bag 1 slides on at least one remaining in the dispenser box Bag 1.
