Abstract

A method of producing a packaging container, in particular for providing a box with a binding comprising a thread-like or strip-like auxiliary packaging component, such as a band or the like, and for decorating the packaging container with a bow. In order to make the method more flexible, in particular in order to allow partial automation, according to the invention, first of all a carrier is prefabricated with the auxiliary packaging component, and then the auxiliary packaging mechanism is transferred from the carrier to the packaging apparatus.

Description

The present invention relates to a packaging method for a packaging container, in particular for Equipping a box with a lacing from one filament or strip-shaped packaging aids, such as a cord, ribbon or the like, and to decorate the Packaging container with a loop. Furthermore concerns the invention the technical means for carrying out a such procedure.

In addition to the function of protecting the packaged goods from Loss of quality and simplification of storage and Transport also enables packaging to be factory-made Equipment of the packaged product and offers possibilities for advertising design. One of those ways is not a packaging container to be provided only with a lacing, but also with to decorate a loop. In particular it has one attractive packaging meaning for goods that often are intended as gifts, such as chocolate or chocolates. The latter are mostly packed in boxes that can have different shapes, in the simplest and widespread cases, however, cuboid are trained. When packing, if it is Food or luxury food is, not metallic Tools such as brackets or the like can be used.

While producing straps for example cuboid packaging containers automatic and semi-automatic Strapping machines are known, by means of which Tapes, wires, cords, etc. with seals, clamps, twists, Knots and / or bonds as closures is to tie an automation loop more difficult to access. The ends of a thread or strip-shaped packaging aids, such as one Cord, ribbon or the like. To decorate a Packaging container with a loop in loops and are intertwined in a certain way. Here is a perfect shape of the loop for one attractive packaging essential. In the book "Gifts lovingly packaged ", Remseck near Stuttgart, 1997 For example, on pages 92-115 individual work steps comprehensive instructions for various Laying ribbons and tying loops specified. Such packaging is usually done - too in the production of packaging in large quantities - manually and is associated with a considerable amount of work. The thread-like or strip-shaped packaging aid is used for example in the operation of a piece goods cut, laced and tied into bows. With a high production throughput, a large workforce is required be tasked with this work.

The present invention is therefore based on the object with high quality of the assembled packaging container to make a process of the type mentioned in the introduction more flexible, thereby a cost advantage in manufacturing to achieve and / or the method the possibility to open a partial automation. Another job the invention is the technical means for To carry out such a procedure.

This task is accomplished by a manufacturing process of solved the type mentioned, in which a prefabrication a carrier with the packaging aid and then the packaging aid from the carrier is transferred to the packaging container. to In addition, an object according to the invention will also be achieved Carrier, a pre-assembly device according to the invention and a prefabricated according to the invention Unit specified.

The idea behind the technical solution according to the invention is based on the desired flexibility through a division the assembly process into individual sub-processes to achieve that advantageously in space and time can be carried out separately. It is the last sub-process, the transfer of the strapping with the loop from the carrier to the packaging container, one Automation more accessible than the entire assembly process.

In this way, the pre-assembled according to the invention is created Unit for the packaging container that comes from the Carrier and the thread or strip-shaped packaging aid exists, the latter after the first Sub-process of assembly with training Lacing and looped on the carrier is attached. Such a prefabricated unit can be easily transported and later Further processing can be magazine.

In the method according to the invention, one can be elastic stretchable thread or strip-shaped packaging aid be used and to transfer this packaging aid from the carrier to the packaging container can the carrier with the by the pre-assembly formed, provided with the loop, from the thread or strip-shaped packaging aids Lacing on the top or bottom of the packaging container be placed with the packaging container at least partially between the lacing and the carrier is then stripped of the strapping from the carrier and is completely slipped on the packaging container, and finally the strap from the lacing and from the Packaging container is removed.

The pre-assembly of the carrier can either only using the carrier or with the help of an additional made according to the invention become. With the use of a finishing device arise, especially when a disposable carrier is used, further material-economic advantages.

Suitable for carrying out the method according to the invention preferably a carrier, which in particular consists of a flexible material is built and one of the packaging container has adapted flat basic shape, wherein a height dimension of the carrier is smaller than a height dimension of the packaging container and preferably also compared to a height dimension of the pre-assembly device if one is to be used. Preferably, the height dimension of the carrier can only be one Fraction of the height dimension of the packaging container be. At least one flat basic dimension of the carrier, like length or width, should be about each a corresponding flat basic dimension, such as length or Width of the packaging container plus at least each each of the height dimensions of the packaging container result.

To carry out the method according to the invention, using Advantage of using a pre-assembly device which in particular is a structure made of a rigid material and a flat basic shape adapted to the packaging container having a height dimension of the pre-assembly device smaller than a height dimension of the packaging container is, and the flat basic dimensions, such as Length and width, each roughly from a corresponding one flat basic dimensions, such as length and width, of the packaging container plus at least the height dimension of the packaging container. The height dimension the pre-assembly device can advantageously larger than the height dimension of the carrier his.

Preferably, such a carrier and such Pre-assembly device are used, which in their respective flat shape in a partial area are congruent to each other.

To carry out the method according to the invention, the further an assembly device according to the invention are used, the holding device for a Packaging container and for a pre-assembled unit has and several movable grippers for detecting the Has strapping.

1 shows an example of a packaging container 1 an almost completely assembled in accordance with the invention essentially rectangular box with a length L, a width B and a height H. The box consists of a bottom part 2, on which a cover part 3 is placed, and is surrounded by a banderole 4 made of cellophane. The Packaging container 1 is with a strapping 5 through thread or strip-shaped packaging aid 6 and carries a bow 7 for decoration. In the present The case is the packaging aid 6 a cord. The strapping 5 has the shape of a cross weave on. But it could also be in the form of a diagonal or a triangular bond.

The loop 7 is made of the packaging aid used for strapping 6 bound. Loop 7 can be used as one or multiple bow, jewelry bow or bow knot be executed. In the exemplary embodiment the loop 7 at a distance X from an end face 8 of the box, which is about 30 to 40 percent of the Length L of the box results. Such a position X the Loop 7 corresponds to the so-called "golden ratio" and is aesthetically appealing in a special way.

According to the invention, one is made up in this way Packaging container manufactured in that a first Pre-assembly of a carrier 9, as exemplified in Fig. 2 is shown as a single part, with the packaging aid 6 and then the packaging aid 6 from the carrier 9 onto the packaging container 1 is transmitted.

For transferring the packaging aid 6 from the carrier 9 on the packaging container 1, the carrier 9 with the formed by the pre-assembly, with the loop 7 provided from the thread or strip-shaped packaging aids 6 existing strapping 5 for example top, as shown in Fig. 1, or also underneath, are placed on the packaging container 1, the packaging container 1 at least partially between the strapping 5 and the carrier 9 is then guided strapping 5 stripped from carrier 9 and the packaging container 1 is completely slipped on, and finally the carrier 9 from the strapping 5 and from Packaging container 1 is removed. That last step must still be carried out with the carrier 9 shown in Fig. 1 be a completely assembled according to the invention Obtain packaging container 1.

As already mentioned, the pre-assembly of the Carrier 9 either using the carrier 9 or with the help of an additional pre-assembly device 10 can be made as an example is shown as an individual part in Fig. 3. In this case is used for pre-assembly of the carrier 9 Packaging aids 6 in the same way as that of the for example shown in Fig. 1, for the packaging container 1 provided strapping 5 around the pre-assembly device 10 laced, with the bow 7 provided and then transferred from there to the carrier 9.

To transfer the packaging aid 6 from the Pre-assembly device 10 on the carrier 9 can Carrier 9 on the top or bottom of the pre-assembly device 10 can be placed. The carrier 9 at least partially between the strapping 5 and the Pre-assembly device 10 performed, then the strapping 5 stripped from the pre-assembly device 10 and the carrier 9 completely slipped on and attached to it. Finally, the pre-assembly device 10 removed from the strapping 5 and from the carrier 9.

It is useful for a good hold on the carrier 9 the thread-like or strip-shaped packaging aid 6 under tension on the carrier 9 or already on the Apply pre-assembly device 10. Therefore, a elastically stretchable thread or strip-shaped packaging aid 6 used. The elasticity of the packaging aid 6 also allows the packaging container without difficulty between the straps 5 and to guide the carrier 9. If the carrier 9 from the already slipped on the packaging container 1, by the bias slightly stretched strapping 5 and from Packaging container 1 is removed, the packaging aid 6 contract again elastically and one sufficiently tight strapping 5 around the packaging container 1 form.

If one starts from a box as packaging container 1, as described above and shown in FIG. 1, a preferably recommended percentage stretchability of the packaging aid 6 can be estimated: assuming that a loop 7 is provided when the finished one is transferred If the strapping 5 is pulled from the carrier 9 onto the packaging container 1, the strapping 5 is pulled over a corner 11 of the packaging container, a packaging aid 6 should be used which has at least approximately a percentage extensibility by an amount F which increases F = ( Z Y -1) * 100% results. The size Z stands for an extended length of the packaging aid 6 and results in Z = (0.25 B 2 + L 2 ) 0.5 + [0.25 B 2 + ( L - X ) 2 ] 0.5 + H

The size Y stands for an unstretched length of the packaging aid 6 and results in Y = 2 L - X + H , (For a somewhat rougher estimate of this extensibility, the summand H in the above second and third equations can also be neglected.)

2 shows a top view of a carrier 9 according to the invention for carrying out a method according to the invention. The carrier 9 is preferably made of a flexible material and has a flat basic shape adapted to the packaging container 1. Its height dimension (thickness D _T - FIG. 1) is small compared to a height dimension (height H) of the packaging container 1. If, as in the exemplary embodiment shown here, a pre-assembly device 10 is to be used, the thickness D _{T of} the carrier 9 should preferably also be small compared to a corresponding height dimension of the pre-assembly device 10. This height dimension of the pre-assembly device 10 is preferably the thickness (not shown in the drawing) of the pre-assembly device 10 shown in FIG. 3 and is referred to below as D _VK . At least one flat basic dimension (length L _T , width B _T ) of the carrier 9 should each result approximately from a corresponding flat basic dimension (length L, width B) of the packaging container 1 plus at least in each case the height dimension (height H) of the packaging container 1.

If no pre-assembly device 10 is used, both flat basic dimensions (length L _T and width B _T ) of the carrier 9 should each be approximately from a corresponding flat basic dimension (length L, width B) of the packaging container 1 plus at least in each case the height dimension (height H). of the packaging container 1 result. This means that when using a prefabrication device 10, the carrier 9 can be made shorter in one of its flat basic dimensions (in the example described - in its length L _T ) in a material-saving manner. The carrier 9 described is characterized by a flat basic dimension, namely its largest flat basic dimension (length L _T ), which is approximately one third smaller than the corresponding flat basic dimension (length L, L _VK ; width B, B _VK ) the packaging container 1 (Fig. 1) and the pre-assembly device 10 (Fig. 3).

In order to apply the elastically stretchable thread-like or strip-shaped packaging aid 6 to the carrier 9 under pre-tension, but then in an almost untensioned or hardly tensioned state on the packaging container 1, it is expedient if at least one flat basic dimension (length L _T and / or width B _T ) is increased by the intended amount of stretching of the elastically stretchable filament or strip-shaped packaging aid 6 compared to the values given above. If no pre-assembly device 10 is used, both flat basic dimensions (length L _T and width B _T ) should be increased by the intended amount of stretching of the elastically stretchable filament or strip-shaped packaging aid 6 compared to the values given above. In this case, the carrier 9 could be constructed approximately in the same way as the pre-assembly device 10 described below.

The carrier 9 according to the invention has an end face 12 a groove-like recess 13 for at least partially Inclusion of the packaging aid 6. The recess 13 is preferably as one with a tapered Slotted round hole formed. Also on the two long sides 14, 15 of the carrier 9 is one groove-like recess 16, 17 provided. One of those cutouts 17 is also conical as one with one tapered slot formed round hole; the other recess 16 has the contour of a semicircular Area. The groove-like recesses 13, 16, 17 are for Inclusion of the thread or strip-shaped packaging aid 6 determines that in each case with a Slotted round holes provide a particularly good hold place.

Furthermore, on the two long sides 14, 15 of the carrier 9 open obliquely in the direction of an end face 12 Recesses 18, 19 are provided. These recesses 18, 19 are also to take the thread or strip-shaped Packaging aids 6 determined, but allow particularly easy stripping of the same in the direction of the Front side 12 of the carrier 9 towards which it is opened are.

The two long sides 14, 15 preferably run outwards from their recesses 18, 19 in the direction of an end face 12 towards each other. Through this one-sided tapering The shape of the carrier 9 also becomes light Stripping the from the thread or strip-shaped packaging aid 6 formed strapping 5 in the direction of supports the end face 12 of the carrier 9.

Due to this convergence of the longitudinal sides 14, 15 of the carrier 9 starting from the recesses 18, 19, the recesses 18, 19 have an essentially obtuse-angled contour and thus form contact or abutting edges for the packaging aid 6 over the height H _{T of} the carrier 9.

The carrier 9 can advantageously be made of cardboard or cardboard, preferably solid cardboard with a height dimension (thickness D _T ) of approximately 0.3 to 0.7 mm. Manufacturing from plastic is also possible. The use of such materials also offers the possibility of reuse and simple recycling.

3 shows a plan view of a pre-assembly device 10 according to the invention for carrying out a method according to the invention. In contrast to the carrier 9, the pre-assembly device 10 is constructed in particular from a rigid material. Like the carrier 9, the pre-assembly device 10 also has a flat basic shape adapted to the packaging container 1, a height dimension (thickness D _VK ) being small compared to a height dimension (height H) of the packaging container 1. The flat basic dimensions (length L _VK , width B _VK ) each result approximately from a corresponding flat basic dimension (length L, width L) of the packaging container 1 plus at least in each case the height dimension (height H) of the packaging container 1.

For the same reasons as explained above for the carrier 9, it can also be expedient in the case of pre-assembly device 10 if at least one flat basic dimension (length L _VK , width L _VK ) is enlarged by an amount of stretching of the elastically stretchable thread-like or strip-shaped packaging aid 6.

The pre-assembly device 10 has on both of them End faces 20, 21 each have a groove-like, preferably in Form a V notched recess 22, 23. This groove-like Recesses 22, 23 are for receiving the thread or strip-shaped packaging aid 6 determines that on the one hand, a good hold in the V-shaped notches finds, on the other hand, however, for transfer to the carrier 9 also easily removed from the cutouts 22, 23 can be. When tying up the pre-assembly device 10 is also through the groove-like recesses 22, 23 centering of the packaging aid 6 is guaranteed.

Furthermore, as with the carrier 9 are on the two Long sides 24, 25 of the pre-assembly device 10 opened obliquely in the direction of an end face 20 Recesses 26, 27 are provided. These recesses 26, 27 perform the same function as the recesses 18, 19 on the carrier 9.

In an analogous manner to the carrier 9 and with the same as described for carrier 9 (simplification the stripping of the strapping 5) also run the two Long sides 24, 25 preferably starting from their recesses 26, 27 in the direction of an end face 20 towards each other.

Here, too, due to this convergence of the longitudinal sides 24, 25 of the pre-assembly device 10, the recesses 26, 27 have an essentially obtuse-angled contour and form contact or abutting edges for the packaging aid 6 over the height H _{VK of} the pre-assembly device 10.

From all this it can be seen that the carrier 9 and the pre-assembly device 10 preferably one level each Have shape that is essentially in a partial area (apart from the shape of the recesses 13 or 22) are congruent to each other. The congruent part each comprises at least one end face 12 or 20th and the area of the long sides to be converged 14 or 24 and 15 or 25 including the recesses 18 or 26 and 19 or 27. Because of this congruence is the transfer of the strapping 5 from the pre-assembly 10 on the carrier 9 in particular Way favors.

As illustrated in FIG. 3, an inclined side 28 is also provided on the pre-assembly device 10, which runs from an end face 21 to a longitudinal side 24 in the left half of the pre-assembly device in the drawing. The end face 21 in this half preferably has a distance A _VK to the other end face 20 in the region from its edge 29 with the inclined side 28 to the groove-like recess 23 therein, which is approximately half the depth of the recess 23 with respect to the total length L. _{VK of} the pre-assembly device 10 is shortened. As a result of this configuration, the strapping 5 formed on the pre-assembly device 10 can be stripped off the pre-assembly device 10 in a few simple steps and without overstretching the packaging aid 6 for transfer to the carrier 9. For this purpose, it can easily be taken out of the groove-like recess 23, over the shorter spaced part of the end face 21 to its edge 29 with the inclined surface 28 and then over the inclined surface 28 itself.

If boxes with a height of about 30 mm are to be assembled as packaging containers, the pre-assembly device 10 can advantageously be made of a plastic with a height dimension (thickness D _VK ), preferably in the range of about 3 to 7 mm. If a preferably transparent plastic, such as PMMA or POM, is used as the plastic, this additionally improves the recognizability of the respective position of the packaging aid 6 on the front and back of the pre-assembly device 10.

4 and 5 show an inventive and front Prefabricated unit 30 for a packaging container 1 as after a transfer of a strapping 5 including loop 7 from a pre-assembly device 10 on a carrier 9 is formed. The Prefabricated unit 30 consists of the carrier 9 and the thread-like or strip-shaped packaging aid 6 (Cord). The packaging aid 6 is under training the strapping 5 and provided with the loop 7 on the Carrier 9 attached.

The strapping 5 was carried out on the pre-assembly device 10 in the same way as later provided for the packaging container 1 in the form of a cross weave, provided with the loop 7 and then transferred to the carrier 9 in the manner described. On one end face 20 or 12, the part of the strapping 5 running along the length L _{VK of} the pre-assembly device 10 was transferred from the recess 22 of the pre-assembly device 10 into the recess 13 of the carrier 9. The part running along the width B _{VK of} the pre-assembly device 10 Part of the strapping 5 was transferred from the recesses 26, 27 of the pre-assembly device 10 into the respectively congruent recesses 18, 19 and is held on the pre-assembled unit 30 between these recesses 18, 19 under a slight prestress.

As already mentioned, the length L _{T of} the carrier 9 is at least about a third smaller than the length L _{VK of} the pre-assembly device 10. The part of the strapping 5 running through the cutout 23 on the lower end face 21 of the pre-assembly device in FIG. 3 along the length L _{VK of} the pre-assembly device 10 can therefore not be brought into a corresponding cutout in the carrier 9. Instead, a section of this part, after it has been stripped off by the pre-assembly device 10, is shifted laterally (on the left in FIG. 4) along the longitudinal side 14 of the carrier 9 and is guided through the recess 16 with the semicircular contour located there. On the other hand, a second section of this part is placed in a loop 31, which is hooked into the recess 17 (on the right-hand side in FIG. 4) of the longitudinal side 15 of the carrier 9. This results in the guidance of the cord shown in FIG. 4 on the front of the carrier 9. To transfer the strapping 5 from the carrier 9 to the packaging container 1, the loop 31 can be removed from the recess 17 in a simple manner.

Fig. 5 illustrates the course of the strapping on the back of the carrier 9. The strapping 5 formed from the thread-like or strip-shaped packaging aid 6 (cord) is also on the back of the carrier with a slight bias across the width B _{T of} the carrier 9 between the two recesses 18, 19 held. The part of the cross binding of the cord that later runs on the packaging container 1 along its length L instead runs obliquely over the back of the carrier - starting in the recess 13 at the end face 12 (in FIG. 5) and ending in the groove 16 with the semicircular contour the (in FIG. 5 right) long side 14 of the carrier 9.

To ensure easier portability of the Strapping 5 are the later on the packaging container 1 along its length L and later along its length Wide B-running part of the cross weave on the back of the carrier 9 at their crossing point 32 with each other looped.

It is also - also as a section of the later on the packaging container 1 along its length L. Part of the cross tie of the cord - on the other (in Fig. 5 left) longitudinal side 15 of the carrier 9 in the there located recess 17 hanging loop 31 of the strapping 5 to see.

4 and 5 show the course of the packaging aid 6 on the pre-assembled unit 30 advantageously chosen such that one side, namely the Front side, the carrier 9 free of the strapping 5th remains. This free end can be used for assembly the packaging container 1 easily between the Constriction 5 and the carrier 9 are performed.

Starting from this pre-assembled unit 30, the easily transported, temporarily stored and arbitrarily can be stored for a long time, it is in a few easy steps possible the final assembly of a packaging container 1, but it is also possible for this purpose an assembly device according to the invention 100 use, their structure and mode of operation is shown below. It becomes exemplary Reference to the one described above prefabricated unit 30, although an inventive The assembly device 100 is also designed in this way can be that pre-assembled units with other Shape or with a different course and a different Attachment of the strapping 5 used on the carrier 9 can be.

The basic structure of the assembly device according to the invention 100 illustrates Fig. 6. As the most important function The assembly device has parts on the one hand a holding device 101 for the packaging container 1 and for a pre-assembled unit 30 and on the other several movable grippers 102 for gripping and Tighten the strapping 5. The pre-assembled Unit 30 consists - as an example in Fig. 4 and 5 shown - from a carrier 9 and from one with a Loop 7 provided, from a thread or strip-shaped Packaging aids 6 formed strapping 5.

The holding device 101 consists of an upper holding plate 103 and a lower holding plate 104. Both plates 103 and 104 are arranged essentially horizontally one above the other, their mutual distance being adjustable. For this purpose, the upper holding plate 103 is fastened to an essentially vertical linear guide 105 (direction of movement according to arrow R1). Both holding plates 103, 104 can be rotated or pivoted together in their plane of extension by means of a rotary drive 106 (direction of movement according to arrow R2). Between the holding plates 103, 104, the packaging container 1 or the prefabricated unit 30 can be held (clamped), whereby the mutual distance between the holding plates 103, 104 can be adjusted to adapt to the height H of the packaging container 1 or to the Thickness D _{T of} the carrier 9 can take place.

So that when the pre-assembled unit 30 in the Holding device 101 is held, enough space available for the tying 5 and for the loop 7 stands, can preferably face each other Sides of plates 103, 104 channels respectively one Recess can be provided that the course of the tying 5 or the position of the loop 7 on the pre-assembled Unit 30 correspond. For the same purpose, the Carrier 9 where in the pre-assembled unit 30 Loop 7 comes to rest, have an opening.

The number of movable grippers 102 for detecting the Constriction 5 can be different if necessary. In the execution shown are for detecting the cross-tie seven grippers 102 are provided, namely a first gripper module 107 of three grippers 102 in the area of the upper holding plate 103, a second gripper module 108 of three grippers 102 in the area of the lower holding plate 104 and a third gripper module 109 from a gripper 102 in one Area outside the holding plates 103, 104. The grippers 102 of the first module 107 and the second module 108 the course of the strapping 5 on the pre-assembled Unit 30 positioned accordingly. They take action Holding plates 103, 104 from above and below and are common movable with the holding plates 103, 104. You can next their possibility of carrying out the gripping movement a maximum of two degrees of freedom of movement - one degree of freedom for a translatory movement R1 (caused by the linear guide 105) and a degree of freedom for the rotary motion R2 (caused by the rotary drive 106). For setting the distance between the Plates 103, 104, it is sufficient if only one Holding plate (e.g. the upper holding plate 103 as shown including the gripper 102) is adjustable in height is, so that in this case the number of Degrees of freedom in the lower gripper module 108 reduced by 1.

The gripper 102 of the third gripper module 109 is of this type agile that in addition to its possible gripping movement Infeed movement to that positioned in the holding device 101 pre-assembled unit 30 and a rotary movement run around a substantially horizontal axis can. He has three degrees of freedom of movement, for translational movements in two directions (effected on the one hand by an essentially horizontal Linear guide 110 - direction of movement according to arrow R3 - and on the other hand by an essentially vertical linear guide 111 - Direction of movement according to arrow R4) and for rotary motion (caused by a rotary drive 112 - Direction of movement according to arrow R5).

To attach the above-described items of the invention Assembly device serves - as Fig. 6 shows - a frame 113.

7 to 10 illustrate the operation of the invention Packeting.

The essence of the packaging basically exists in that to transfer the packaging aid 6 from the carrier 9 a pre-assembled on the packaging container 1 Unit 30, which consists of the carrier 9 and provided with the loop 7, from the thread or strip-shaped Packaging aids 6 formed strapping 5 consists of the assembly device 100 and is fixed in the holding device 101, the strapping 5 first by the movable grippers 102 detected and then by the height H of the packaging container 1 is lifted from the carrier 9. The carrier 9 is then removed, and the packaging container 1 is between those of the grippers 102 grasped and lifted (pulled apart) Tie 5 brought. Then the strapping 5 on the packaging container 1 in the correct position positioned and finally the strapping 5 from the Grippers 102 released so that the packaged packaging container 1 from the assembly device 100 can be removed.

7 shows a first work step. First will the pre-assembled unit 30 (Fig. 4) on the lower Holding plate 103 positioned. 4 with the reference symbol 12 designated end face of the carrier 9 comes corresponding to the pictorial representation in Fig. 7 on the Side of the frame 113 to lie; the in Fig. 7 with the Reference numeral 33 designates the opposite end face protrudes between the two holding plates 103, 104 out.

Then move the vertical linear guide 105 the upper holding plate 103 towards the lower Lower holding plate 104 (arrow C) until both plates 103, 104 lie one on top of the other and thus the carrier 9 fix. During this linear movement, the grippers 102 of the first and second gripper modules 107, 108 opened, then in the next step, the strapping 5 to the intended positions from above and below can.

This happened in the working phase shown in FIG. 8. Since the strapping 5 is still attached to the carrier 9 is and therefore no opening for receiving the packaging container 1 forms with the help of the two linear guides 110, 111 for the gripper 102 of the third gripper module 109 moved to a position of the strapping 5, which is approximately in the center of the support 9 is located (according to FIG. 4 in the section between the two lateral recesses 16 and 17). At the same time, the gripper 102 of the third gripper module 109 opened.

The fastening aid 6 (the cord) is now on seven points are gripped by all the grippers 102 at the same time. Then the upper holding plate 103 is about the Height H of the packaging container 1 moved up and so the strapping 5 pulled apart. Moved at the same time the gripper 102 of the third module 109 to the side and is rotated approximately 90 ° by the rotary drive 112. So that the strapping 5 is opened such that the packaging container 1 can be carried in like this Fig. 9 shows. Before this happens, the carrier 9 away.

After positioning the packaging container 1 between the two plates 103, 104 this is already (in the Seen from above) on three sides (e.g. on one end face 8 and on both long sides) of the strapping 5 surround. Are now effected by the rotary drive 106 the lower and the upper holding plate 103, 104 with the between them lying packaging container 1 rotated so that that held by the gripper 102 of the third module 109 Section of the fastening aid 6 over the last from the tie 5 not yet drawn side becomes.

To remove the assembled packaging container 1 and to assemble a new packaging container 1 repeat the steps described above allow to open up in a final step of the assembly device 100 according to the invention Grippers 102 and move to their home position.

The invention is not based on the described embodiment limited, but also includes all in the sense of Versions with equivalent effects. For example can the packaging container 1 in its flat contour instead of rectangular also triangular, hexagonal, octagonal or be round. As mentioned before, too possible to use another type of strapping 5, e.g. a Diagonal or triangular binding, without the Is left within the scope of the invention.

The shape of the corresponding carrier 9, the pre-assembly device 10 including the location of any therein provided recesses and recesses and the number and position of the grippers 102 of the assembly device 100 is then appropriate in these cases the shape of the packaging container and / or the type to adapt the strapping 5.

The loop 7 does not necessarily have to come from the packaging aid 6, but can also be added later applied to or on the packaging aid 6 be attached. If there is no cord for the strapping 5 to be used, those provided on the carrier 9 can be used Recesses 13, 16, 17 advantageously to the shape and Strength of the corresponding packaging aid 6 adjusted become.

Around the one held by the gripper 102 of the third module 109 Section of the fastening aid 6 over the last pull the side not yet surrounded by the cord 5, do not necessarily have the lower and upper holding plate 103, 104 with the packaging container lying between them 1, but it could also be the Gripper 102 of the third gripper module 109 rotated or be pivoted. The rotary drive could then correspondingly 106 for the plates 103, 104 are omitted. It should but then the gripper 102 essentially one vertical axis rotating rotation drive provided become. However, the variant described above is preferred because they are characterized by a higher stability of movement distinguished and thus a consistently high quality of Assembling ensures what is generally through the Assembling device 100 guaranteed shall be.

To implement those not described in detail above Feeding and removal of the packaging container 1 and the Feeding of the pre-assembled unit 30 and removal of the carrier 9 can in the assembly device according to the invention 100 different technical solutions for Application come. For example, to remove the Packaging container 1, a pneumatic suction cup is provided his. The supply of the pre-assembled unit 30 and of the packaging container 1 and the removal of the carrier 9 can advantageously each correspondingly via gripper arms Feeding and removal devices take place. It is favorable in terms of production technology if several assembly devices 100 are provided, which described Carry out work steps in intervals and thus alternately from each of the gripper arms of the feed and Removal devices can be operated.
