DESCRIPTION

Procedure and device for manufacturing one-piece flat scraps, made of a folding material, in particular wrapping paper

The invention relates to a method for manufacturing flat, one-piece cutouts, made of a folding material, in particular gift wrap, foils or the like, for wrapping packages, in particular for packaging different cube or square shaped objects. The invention also relates to a device for executing the method.

When buying gifts, for example cosmetics, jewelry or books, the customer often requests that the purchased gifts be additionally wrapped in gift wrap at the corresponding store's checkout. Fulfilling this request involves relatively time-consuming operations, because it is not only necessary to cut the wrapping paper, for example from an unwinder, according to the dimensions of the gifts, but also to perform a series of folding operations to wrap the gifts. On public holidays in particular, for example Christmas, Easter or Pentecost, long waiting lines are formed in front of the cashiers of the corresponding shops, because the cashier also takes care, in addition to charging, to wrap the objects bought in wrapping paper.

Since different gifts often also have different dimensions, it is generally not possible for reasons of space to keep a quantity of prepared wrapping paper cutouts in the box or in a central packing area to facilitate the wrapping operation.

From document US2013 / 0000252A1 a method is known, in which the object to be packaged is optically measured and then a corresponding package is created.

Document WO97 / 24262A2 describes an automatic packaging device for boxes.

From document US2017 / 0210500A1 an automatic packaging system is also known. Document US2004 / 060264A1 discloses a device or a method for manufacturing one-piece flat cutouts for wrapping packages, the dimensions of the objects to be packaged being automatically previously determined and then a corresponding cutout is created by means of a cutting device computer controlled.

The object of the invention is to provide a method that makes it possible to essentially reduce the time required to wrap objects to be packed with foldable material. The invention also provides a device for executing this process and a cutout manufactured according to this process.

According to the invention, the object is achieved with respect to the method by the features of claims 1 or 2 and with respect to the device by the features of claims 6 or 7. The sub-claims disclose other particularly preferred configurations of the invention.

If the corresponding objects must preferably be packed manually, for example for reasons of space (as is generally the case, for example, in a shop box), the invention essentially proposes (claim 1) to determine first from the dimensions of different objects to be packed possibly the dimensions (edge contours) of corresponding cutouts that enable a simplification of the packing process. The dimensions of these cutouts are then stored as digital data in an electronic memory. After selecting a specific object to be packed, the folding material (wrapping paper), stored in roll form, is automatically unwound from an unwinder by means of an extraction device and the digital data, assigned to the cut-out of this object, is transmitted to a computer controlled cutting device that then creates a corresponding cutout. With this cut-out, the corresponding gift is then packed manually (or, if necessary, automatically).

If the gifts are to be packed in the box area, it is advantageous if the digital data corresponding to the dimensions of the different cutouts is stored in a memory of the box (electronic). In this case, the checkout staff only need to enter a predefined code for the object to be packed in the box or press a button and the cutout, assigned to the object to be packed, is automatically created by the cutting device.

For the entry of the code, which characterizes the object to be packed, for example, a scanner can be used that scans a bar code located on the object to be packed and characteristic of the dimensions of the object to be packed.

However, it may also be provided that the digital data, corresponding to the dimensions of the cutout, is stored in a memory chip integrated in the object to be packed, so that this memory chip is read by a box reader or a reader of the device to manufacture the respective cutout.

The cutting device is preferably a laser cutting device. This may comprise, for example, two lasers displaceable transversely to the transport direction of the foldable material, each laser generating a laser beam that cuts one of the opposite lateral edge areas of the foldable material in correspondence with the predefined contour.

However, it can also be provided that only one laser is provided, the corresponding laser beam being divided by a splitter into two laser beams which are then used respectively to cut the edge areas of the foldable material.

As cut-outs for wrapping cube- or square-shaped containers, it has been advantageous for the front surfaces, as well as the upper and lower surfaces of the respective object to be packaged, correspond to surfaces of essentially equal size of the cut-out, which are axially joined one to the other. another in the direction of wrapping, and that essentially triangular surface sections are laterally attached to each of these surfaces which have been selected in such a way that after the object is packed they jointly cover the side surfaces of this packaging. This type of cut-outs enables particularly fast packaging of containers.

To essentially simplify the packaging process, the cutout should have a tab-shaped surface section provided with a layer of adhesive, which at the beginning of the packaging process is attached to a first surface (for example, the first front surface) of the object to be packed and to which the other surfaces of the cutout are then attached during the wrapping process and which is covered with the remaining surface of the cutout at the end of the wrapping process.

The marginal lines of the triangular surface sections can also have, for example, an outwardly curved (convex) contour.

If there is enough space to pack the corresponding objects (for example, when the objects are packed in a dispatch center), it has been advantageous not to analyze the dimensions of the possible objects to be packed beforehand or to store their cut-out data in order to use them later. to pack a specific object to be packed, but to determine online the dimensions of the specific object to be packed and to determine directly with the help of these data the desired data for the computer-controlled cutting device.

If the packaging process is carried out automatically with the help of a robot, this robot can preferably also be used to determine the dimensions of the object online. In this case, the dimensions of the object can be determined with the aid of an optical apparatus, the object to be packed and the optical apparatus being positioned relative to each other with the aid of the robot.

A variant of the invention consists in that the foldable material is provided with a plurality of perforations and the foldable material is placed on a support surface with a plurality of air suction holes and the object to be packed in each case is placed on the Collapsible material and the object to be packed is secured in position on the collapsible material by suction of air through the air suction holes. This facilitates the packaging process, whether done manually or mechanically.

Other details and advantages of the invention are derived from the following embodiment examples explained by means of the figures. They show:

Fig. 1 the block diagram of a device for executing the method, according to the invention, for manufacturing a gift wrap cutout; and

FIG. 2 is a perspective view of an object to be packed when the object is manually wrapped with the cut-out according to the invention.

In figure 1, a device for manufacturing one-piece flat cutouts 2, made of wrapping paper, for wrapping packaging is identified with the number 1. For a better understanding, a plan view of cutout 2 was represented here.

Device 1 is assigned an apparatus 3 for automatically determining the dimensions of possible objects 4 to be packed later. This comprises, for example, two cameras 5, the signals of which are transmitted to a computer 7 by means of an analog-digital converter 6. The computer 7 determines the dimensions of the cut-outs 2 of the corresponding wrapping packages, for example, with the aid of a image recognition software, starting from the dimensions of the different objects 4 to be packed and then storing them as digital data in an electronic memory 8, for example, of the computer 7 of an electronic box.

The computer 7 interacts with an extraction device 9 of an unwinder 10, in which there is a roll of wrapping paper 11, and with a laser cutting device 12 connected downstream of the extraction devices 9. The computer 7 is also connected to a keyboard 13 (eg a box keyboard) and a scanner optical 14.

If a customer wants, for example, to wrap a specific object 15 in gift wrap (in the case shown, it is, for example, a square gift box with two front surfaces 16, 17, an upper surface 18, a lower surface 19, as well as two side surfaces 20, 21), communicates this to the cashier who then enters a code corresponding to this object 15 via the keyboard 13 or scans a barcode 12 printed on the object 15.

The computer 7 automatically controls the extraction device 9 so that the wrapping paper 11 is removed from the unwinder 10 and passes through the laser cutting device 12. According to the digital data stored in the memory 8 a cutout is then created 2 showing the predefined edge outline for the corresponding object 15.

To this end, the laser cutting device 12 may comprise two lasers (not shown) which are displaceably arranged transversely to the direction of transport 100 of the cutout 2 in such a way that each laser cuts an opposite lateral edge region 23 , 24 of the folding material in correspondence with the predefined contour.

As can be seen in figure 1, cutout 2 has four surfaces 25-28 that correspond to the dimensions of the front surfaces 16, 17, as well as the upper and lower surfaces 18, 19 of the object to be packed 15. The front surfaces 16, 17 of the object 15 to be packaged here correspond to the surfaces 26, 28 of the cutout 2 and the upper and lower surfaces 18, 19 of the object 15 to be packed correspond to the surfaces 27, 25 of the cut-out 2.

The side surfaces 20, 21 of the object 15 to be packaged are instead covered by the marginal triangular surface sections 29-39 and 33-36, each side surface 20, 21 being covered by four triangular surface sections 29-32 and 33-36 corresponding size.

The cutout 2 is also provided at one end 37 with a flange-shaped surface section 38 which has an adhesive layer 39 in a partial area.

To wrap the object 15 in the gift wrap cutout 2 (see also figure 2), the checkout staff places the object 15 to be packaged on the cutout 2 in such a way that the lower edge 40 of the first front surface 16 of the object 15 is located on a reference line 41 which is formed by the transition between the flange-shaped surface section 38 and the surface 25. Next, the flange-shaped surface section 38 is folded up and fixed with the front surface 16 of the object 15 by the adhesive layer 39.

The wrapping process is then finished, that is, the cutout 2 is placed around the object 15, so that the surface 26 rests on the second front surface 17 of the object, the surface 17 rests on the upper surface 18 of the object 15 and the surface 28 rests on the first front surface 16 (on the flange-shaped surface section 38) of the object to be packaged 15. Then, the cutout 2 placed around the object 15 to be packaged is fixed, for example, by means of a tape tesafilm adhesive in tab surface section 38.

At the end of the wrapping process, the triangular surface sections are folded up on both sides of the object to be packed, so that they completely cover the side surfaces of the object to be packed, and are subsequently fixed in each case also by means of an adhesive tape. tesafilm.

The invention is of course not limited to the exemplary embodiment described above.

Thus, for example, at the beginning of the wrapping process, the tab-shaped surface section can also be fixed on another surface of the object 15 (for example, on the other surface 18), so that the last surface 28 of the cutout 2 rests on this surface when the wrapping process is complete.

The triangular surface sections 29-32 and 33-36 may also have, for example, an outwardly directed curvature.

Likewise, the digital data, corresponding to the dimensions of the cutout 2, can be stored in a memory chip attached to the object to be packed 15, so that the computer 7 extracts the data required to manufacture the respective cutout 2 of this memory chip and a corresponding barcode can be removed on the objects to be packed.

Although the method according to the invention has proven to be particularly advantageous for the packaging of cube and square-shaped objects, which may also be external packaging, if necessary, it is not limited to this type of packaging. Thus, for example, with the method according to the invention it is also possible to produce cutouts for other angular objects to be packaged. It will only be necessary to previously determine the corresponding trim due to the dimensions of the objects to be packed and store the corresponding data in a memory, which the computer then has access to if necessary.

In order to further simplify the packaging process for the checkout staff, the computer controlled cutting device 12 may also comprise a printer that prints corresponding fold lines on the cutout (indicated by dashed lines in Figures 1 and 2).

This type of computer-controlled printer 7 can also be used to first print, before the cutting process, cut lines on the folding material 11. These cut lines are then scanned by a scanning device and the scanning signals They are used to control cutting tools.

If there is enough space to pack the corresponding objects 15, the dimensions of the particular object 15 to be packed can also be determined online, for example with the aid of a robot-supported optical device. In this case, the apparatus 3, schematically represented in figure 1, serves to determine the dimensions of the object 15 to be packed concretely, so that it is possible to eliminate the scanner 14 and a code of the object 15 to be packed, etc.
