Abstract

The carrying handle (3) is fixed flat and immovable at its two ends to the outside of the container wall (4,5) by wider reinforcement tabs (10). In the initial state (8) the carrying handle is folded Z-shaped near at least one of the two reinforcement tabs. The Z-shaped fold can have at least one folded edge directed at right angles to the longitudinal extension of the handle. When making the container a strip of material the length of the handle is provided with the wider tabs at the ends and also with the z-shaped fold. This prefab. handle is then fixed flat against the wall of the unfilled or previously filled container. This is achieved in a packing machine where the handles are transferred by suitable supply devices. USE/ADVANTAGE - The containers can be readily stacked without protruding handles. The containers and handles can be made of recyclable materials.

Description

The invention relates to a packaging container for liquid packaged, powdery or lumpy packaged goods with one end mutually opposite wall or order cover parts attached bow-shaped handle made of egg a flat, flexible material that comes from an exit state in which it is flat on the packaging container lying close to the outside, in one of them protruding use condition designed to be transferable is. In addition, the invention relates to a Ver drive to manufacture such a packaging ratio and a device for carrying out this procedure.  

For example, for packaging washing powder it is known to have a rectangular fold in cross section box to use, if necessary with provided with a reinforcement insert and in the filled state is tightly closed. To Er Ease of handling by the buyer is on the folding box be a bow-shaped handle consolidates, which is usually from a flat art strips of material material, which ends by means of two metal rivets on opposite Box walls is anchored. In his ge This bow-shaped stretcher is in the state of use reached at a distance above the top wall of the ge filled carton so that it easily from the User can be taken.

Such filled packaging from the manufacturer containers regularly in large packs, e.g. on pallets, close together and one above the other Delivered stacked. Because a protruding handle like handle for proper stacking a predetermined number of these packaging containers would be annoying, it is known in practice the handle when attaching first in one Arrange initial state in which it lies flat close to the top or side walls of the ver packaging container, for example the fold mentioned box, is laid out so that he the Outline of the packaging container only insignificant changed. At about from DE-PSen 37 28 597, 38 01 791, 38 44 483 or DE-OSen 36 24 888, 36 24 889, 36 24 890 and 36 24 891 known Aus for this purpose, the handle is the handle provided with an elongated hole at each end,  which the metal rivet engages and which allows the handle around the common axis of the two ge to pivot opposite metal rivets as well to move it laterally compared to this. Also featured on the walls of the packaging container bags made of plastic material Similar guides have already been provided in which the end regions of the carry handle included therein are longitudinally displaceable. The first time The handle is used by the user its close to the packaging container Starting position transferred to the use position, in which he then until the packaged goods are used up remains.

The use of such metal rivets for attachment the handle is for what is required today Recycling of packaging, often made of cardboard undesirable; on the other hand, such metal rivets only attached when the packaging is empty be because they're either from the inside set or at least when riveting on the Inside of the packaging container by means of counterholders have to be supported. Also the need relatively strong strips of plastic material to use, which guarantee that that when used on the metal rivets not tear out formed bearing points, stands the Against easy recycling.

The object of the invention is therefore to be a manufacturer packaging equipped on one side with a handle relationship, as well as a method and an apparatus  to create it that is there characterized by that the attachment of the stretcher handles no significant increase in price of the container entails niss, the handle itself one convenient handling and good stacking options for ensures the filled packaging container, and and finally the packaging's recyclability through the handle and its type delivery is not impaired.

To solve this problem, the above is Packaging container according to the invention thereby characterized records that the handle in the area of his the ends together with one assigned to it Reinforcement tab of greater width on the outside ordered wall or wrapping part flat lying and immovably fixed, and that in that Initial state of the carry handle nearby at least one of the two reinforcement tabs folded in a Z-shape is.

The reinforcement tab ensures a secure Ver anchor the handle to the packaging container, so that even with heavy packaged goods your tearing of the Carrying handle is excluded. The manufacturer provided Z-shaped fold shortens the length of the Handle so far that it is in the initial state close to the top wall or on the side of the Packaging container is kept. Will the stretcher gripped when used for the first time, so the Z-shaped fold opens automatically, with what the handle is the one required for transport Length without additional measures, such as elongated holes or the like, would be required.  

The Z-shaped fold can be at least one in substantially perpendicular to the longitudinal direction of the handle s have aligned folding edge. In this way it is possible to arrange the kind to meet that in the initial state of the stretcher gripped tightly over the top of the ver packing container is kept taut. Should in the initial state, the handle on the side of the Packaging container should be kept tight - while in transport or use condition above the top side of the packaging container runs - so it is appropriate that the Z-shaped Fold at least one obliquely to the longitudinal Extension of the handle aligned folding edge having. By appropriate choice and combination of folding edges oriented at right and oblique angles can in itself each for the respective form and shape convenient location of the packaging Handle in the initial state as well as in the subsequent state of use can be achieved. The length of the folds of the Z-shaped fold as well where appropriate the number of folds allow one for practically every packaging container Wall-free tight contact of the handle on the container nis outside in the initial state and a handle Favorable bow-like shape for use to achieve condition.

The reinforcement tab is advantageous to each End area of the handle designed to cover, which is why they have the end of the handle taking groove-like depression can have is designed in the form of an embossing, for example.  

In principle, it is also conceivable to use the reinforcement tab on the actual handle cut the forming material strips at the ends and that between the two end reinforcements flap remaining side parts of the strip to turn inside so that there is a three or more layered structure of the handle results.

Conveniently, the handle is at its end areas together with the reinforcement tabs on the assigned wall or wrapping part glued. Depending on the type of packaging and of the material from which it is made the attachment in another way, for example if necessary, additional brackets or ver weld, happen.

Especially for packaging containers made from Cardboard or paper, it is with respect on the recyclability of great advantage if the handle and / or the reinforcement tab Cardboard or folded paper. For example in at least partially made of plastic Packaging containers can also be desirable be when the handle and / or the reinforcement strap made of appropriate plastic are.

The handle and / or the reinforcement tab may include reinforcement; you can also be built up in layers, as it is it is conceivable that the handle and / or the Reinforcement tab made of a textile product, e.g. a tissue.  

To ensure that when palletizing or when the handling of the filled packaging container before delivery to the consumer of the stretcher did not accidentally reach out of the tight fit releases the initial state and thus the handling handicapped, it is often beneficial when out current state Folds the Z-fold of the handle to each other and / or to the reinforcement tab are attached separably, for example by a Glue point can happen. The first time it is used this connection torn open so that the Z-shaped Folding dissolved and the handle in its bracket formal use position can be transferred.

The type of packaging itself is not one Subject to restrictions. It can be a box or a cardboard or plastic drum - if necessary also coated with it, but the idea of the invention can also be based on Ver apply packaging containers through a the pack good, at least partially enclosing flexible covering are formed. An example of this is in kraft paper Packaged goods in which the handle is on the kraft wrapper is attached.

Attaching the described handle to one Packaging container and thus its final manufacture In individual cases, positions can generally be done by hand respectively; for commercial use, however, are full automatable manufacturing processes required. In such a method according to further Er proceeded in such a way that first one of the Corresponding strip-like length of the handle  Piece of material at both ends with a reinforcement tab of greater width as well provided at least with a Z-shaped fold becomes; the pre-assembled handle becomes along with its reinforcing tabs tight-fitting to produce the initial state on the assigned wall or envelope parts of the packaging container outside at the end immobile Lich attached. The attachment of this prefabricated handle on the assigned wall or wrapping parts can be on the previously filled Container done because of attaching the stretcher handles no intervention in the interior of the container required is. This usually allows that very much high working speed of packing and filling machines without any subsequent hindrance by attaching the handle. From depending on the type of the packaged goods and the existing ones Filling machines it can also be an advantage if the pre-assembled handle on the supplied arranged wall or cladding parts of the flat lying unfilled packaging container be is consolidated. It is useful for both alternatives moderate if the folds of the Z-fold before attaching on the wall or wrapping parts of the packaging to each other or to the respective ver Strengthening tab can be attached so that it is separable this manufacturing step is still part of the pre assembly of the handle is.

For the fully automatic implementation of this procedure can finally use a device which is characterized according to the invention in that  a pre-assembly station for handles in which means for providing the Handles according to cut material strips, for attaching reinforcement tabs at the end areas of these strips of material, as well for folding Z-shaped predetermined portions thereof Strips of material are provided that this precon assembly station via a pre-assembly Transport device that carries the handles is connected to a handle attachment station, of these in cycles with packaging containers or parts of these supply means are assigned to the handle attachment station the supplied containers or their parts individually has receiving mounting elements, the receiving and pressing means for the pre-assembled stretcher handles are assigned, and that they are the precon Assembled handles on the receiving and pressing contains transfer device which transfers the medium.

To ensure an exact positioning of the ends reach the associated handle Reinforcement tabs on the assigned wall parts of the packaging container, it is expedient that the receiving and pressing means Have needle boards on which the prefabricated ned handles in the area of their reinforcement tabs are positively receivable. Such exact positioning of the reinforcement flaps on the outer wall of the packaging containers is especially with regard to a existing printing is desired. Of course Lich the reinforcement tabs themselves can  in turn as part of the pre-assembly of the Carrying handles with a print or a be special design (e.g. oval or circle shaped) if equipped with a back view of the shape and shape of the packaging container nisses appears necessary.

The holding elements for the packaging containers or their parts and the recording and pressing elements can be advantageously used on a cycle basis movable conveyor can be arranged so that results in a work street that adjoins a Connect filling or packing station, or that too can be connected upstream of a filling etc. station, just like this the respective operating conditions pretend.

The mentioned needle boards can finally be used movable pressure members can be arranged, the between a recording position for the precon assembled handles and a pressure position are pivotally mounted.

The new device can be used to attach the stretcher handles on filled packaging containers, e.g. filled and closed folding boxes, or on flat folded empty packaging containers nits, e.g. flat-lying folding box blanks, be set up.

In Figs. 1, 2, a packaging container in Ge is Stalt only one is schematically with their outlines anschaulichten ver, approximately cuboidal folding box 1 illustrated, the reinforcement insert a not visible Ver may contain and, for example, with a powdered packaged goods, such as washing powder, filled . The folding box was erected in a known manner from a blank 2 shown in FIG. 5 lying flat, filled in a filling station and then closed. It is provided with a bow-shaped handle 3 , which consists essentially of a narrow strip of material, which is attached at its two ends to opposite walls 4, 5 . Cardboard or paper (single or multi-layer), with or without reinforcement insert, is particularly suitable as the material for the handle 3 , but the handle 3 can also be made of another flexible material, for example a textile product, such as a fabric or a plastic film (a - or multi-layer) exist. As in the. Fig. 1, 2 indicated by dashed lines at 6 , it runs in the state of use like a handle at a distance above the top wall 7 , so that it can be easily gripped by the user.

To the filled cartons 1 to and piled on each other without obstruction by the protruding handle 3, and without the risk of damage thereto side by side, as for example, is required for pallet transport, the support is attached handle 3 manufacturer side to the folding box 1 in an initial state , as shown in FIGS. 1, 2 with solid lines at 8 a and 8 b. In this initial state, the handle is tightly tightened on the outside of the folding box 1 , so that it practically does not change the outline. In the embodiment of Figure 1, the handle is in the initial state 8 a to the top wall 7 and the two side walls 4, 5 nestles; in the embodiment of FIG. 2, the arrangement is such that in the initial state 8 b of the handle 3 below the top wall to the side walls 4 , 9 , 5 is kept tight.

On the walls 4 , 5 of the folding box 1 , the end regions of the carrying handle 3 are largely glued together with an associated reinforcing tab 10 , the shape of which can be seen in particular in FIGS . 3, 4, in both embodiments. The approximately rectangular reinforcement tab 10 is preferably made of cardboard; it has a greater width than the handle 3 and is provided with a transverse, continuous, groove-like depression in the form of an indentation 11 , in which the end region 12 of the handle 3 is received.

The end region 12 is glued to the wall 4 or 5 of the folding box 1 as well as to the respective reinforcing flap 10 , which, as already mentioned, is glued to the wall 4 and 5, respectively. From similar considerations, it would also be conceivable to turn the end region 12 of the handle 3 into a U-shape and glue it with its free end to the reinforcing tab 10 , so that there is an additional positive connection between the carrying handle 3 and the reinforcing tab 10 .

In the vicinity of the reinforcing tab 10 , the handle 3 is seen in the initial state 8 a or 8 b with a Z-shaped fold 13 a or 13 b, through which the length of the handle and (in the embodiment according to FIG. 2) whose orientation with respect to the attachment points are set so that the handle fits snugly against the outside of the folding box.

In the embodiment according to Fig. 1, the Z-shaped ge folding two perpendicular to the longitudinal extension of the handle 3 , spaced folding edges 14 whose spacing is selected so that the required shortening of the length of the handle 3 results , whose basic orientation in the position of use 6 and in the starting position 8 a is the same.

In the embodiment according to FIG. 4, the Z-shaped fold 13 b only has a fold edge 14 running at right angles to the longitudinal extension of the carrying handle 3 , while a second fold edge 15 is oriented at an oblique angle (at an angle of 45 °) to this longitudinal extension. This arrangement of the folded edges 14 , 15 results in a right-angled deflection of the handle 3 at a short distance above the reinforcing tabs 10 , as is required for the initial state 8 b shown in FIG. 2.

In both embodiments, the Z-shaped fold 13 a, 13 b is temporarily fixed by the manufacturer by means of adhesive points 16 between the individual folds and the reinforcement tab 10 . When used for the first time, these adhesive spots are torn open so that the carrying handle 3 can unfold and change to the use state 6 .

The described handle 3 together with its reinforcing tabs 10 , depending on the circumstances of the respective application, either to a filled and possibly closed packaging container, such as the folding box 1 of FIGS. 1, 2, or to a flat-lying packaging container, such as the Folding box blank 2 of FIG. 5 are attached.

A fully automatic device set up for this purpose is explained in the following in two exemplary embodiments with reference to FIGS. 6 to 15:

In the first embodiment ( FIGS. 6 to 9), the handles 3 are attached to previously filled and closed folding boxes 1 according to FIGS. 1, 2, while in the embodiment according to FIGS. 10 to 14 the attachment of the handles 3 to the flat-lying ones Folding box blanks 5 ( Fig. 3). However, both embodiments work according to the same method.

In this case, for each folding box 1 or each folding box blank 2 , a handle 3 corresponding to the length of the carrying handle is provided in the form of a strip-shaped piece of material. This piece of material is connected at its two end regions 12 each with a reinforcing tab 10 of greater width; it is also provided with two Z-shaped folds 13 a and 13 b. The pre-assembled handle 3 is then fixed together with its reinforcing tabs 10 to produce the initial state 8 a or 8 b tightly attached to the associated wall parts ( 4 , 5 ) of the folding box 1 or the blank 2 on the outside (glued).

In Figs. 6 to 9 only schematically illustrated with its essential elements has Before direction a Vorkonfektionierungsstation I for the handles 3 and a Tragegriffanbring station on II, the transporting by the vorkonfektionier th handles 3 transfer means are connected together at 17 (Fig. 6, 7).

The pre-assembly station I is laterally fed strip-shaped material for the handles 3 (for example cardboard) drawn off from a roll 18 . The direction of conveyance is indicated by an arrow 19 . From this material are cut to length by a cut-off device 20 of the length of a carrying handle 3 ent speaking sections 21 which lie on a chain conveyor 23 working at right angles thereto, which the cut pieces of material at equal mutual intervals in the direction of an arrow 22 ( FIG. 6) transported. On the at the spaced-apart transport chains 24 of the chain conveyor 23 , grippers 25 are provided in pairs for this purpose at corresponding intervals ( FIG. 7), which grip the strip-shaped pieces of material 21 and keep them aligned exactly parallel to one another, through them subsequent processing points to be transported. The grippers 25 are cam-controlled and set up to release the gripped pieces of material at a specific point on the transport path in the area of the transfer or transfer device at 17 .

At a first work station, embossing devices 26 are provided which provide the material pieces 21 gripped by the grippers 25 with the embossing lines corresponding to the folding edges 13 .

In a next job, from two magazines indicated at 27 ( Fig. 6, 7) the unembossed, cardboard reinforcing tabs 10 are individually fed, which are then embossed and provided with glue at 28 in the direction of the arrow ( Fig. 6) with a lifting rake led to the respective piece of material 21 and then placed on the end and pressed onto it so that a secure adhesive connection is produced.

The piece of material 21 thus glued to the two reinforcing tabs 10 is then transported through by folding elements indicated at 29 in FIG. 6, in which the Z-fold 13 a is produced.

In a glue station 30 which is then passed through, the glue points 16 ( FIG. 3) (or glue strips) are applied, whereupon at 31 the folds of the Z-fold are pressed into a flat state by being held at 16 by the gluing. At the work place 32 , the handle 3 is finally prefabricated.

In the subsequent handle attachment station II, a second chain conveyor 33 is arranged, the transport direction of which is the same as the transport direction 22 of the first chain conveyor 23 is indicated by an arrow 34 and which is mounted together with the first chain conveyor 23 in a frame 35 . The second chain conveyor 33 , as can be seen in particular from FIG. 8, also has two transport chains 36 , which are guided parallel to one another at a distance, on which, at regular intervals, a pair of mutually associated holding elements 37 are arranged, which are essentially L-shaped and corresponding to the width of a folding box 1 are spaced apart. The horizontally guided endless transport chains 34 are guided around deflection sprockets 38 , of which a pair of wheels is cyclically driven by a drive motor 40 via a gear 39 , as can be seen in FIG. 8.

Between each pair of holding elements 37 , two swivel levers 41 are provided on each of the two transport chains 36, each of which is pivotally mounted about a swivel axis 42 pointing in the longitudinal direction ( FIG. 9) and form parts of receiving and pressing means. Each of the pivot lever 41 carries in the region of its end a needle plate 43 , which - as can be seen from Fig. 9 - consists essentially of a flat plate 44 , on which, protruding beyond the receiving surface 45 , pointed nails or needles 46 are anchored, whose axial length is dimensioned such that it is less than the thickness of a reinforcing tab 10 and optionally the end portion 12 of the handle 3 . On the other hand, each pivot lever 41 is provided with an actuating roller 47 , which is mounted freely running on a corresponding bearing part 48 , the axis of which includes a predetermined angle, for example of 90 °, with the needle plate 43 .

At right angles to the second conveyor 33 , a feed conveyor 50 is provided ( FIG. 6), which in the conveying direction indicated by an arrow 51 indicates the filled folding boxes 1 in a row butting against each other in the handle-mounting station II. At the discharge-side end of the feed conveyor belt 50 there is a lifting ram 53 , which makes it possible to lift the pushed-on folding box 1 , which is located at the front of the feed conveyor belt 50 , into the vicinity of the lower run of the conveyor chains 36 of the second chain conveyor 33 , as indicated by a double arrow 54 is.

In the conveying direction 34 of the second chain conveyor 33 , a first stationary runway section 55 is arranged next to the lifting ram 53 , to which a movable second runway section 56 is connected in the conveying direction 34 , which is moved by a lifting device 57 from the level of the first section 55 to the level of a third runway section 58 can be raised. At the third roller conveyor section 58 there is finally an output conveyor track 59 on which the finished folding boxes 1 are transported away.

The described device works as follows:

The carrying brackets 3 pre-assembled in the manner already explained are placed by the first chain conveyor 23 at 17 with their reinforcing straps 10 individually on two punches 60 ( FIG. 9), which are arranged in spatial association with the second chain conveyor 33 in such a way that they are separated by two Paired needle plates 43 of the second chain conveyor 33 can be added and carried.

As can be seen from Fig. 8, the two pivot levers on the upper run of the second chain conveyor 33 are held in such a position that their plates 43 lying on a common transverse line point upwards and outwards. In the course of the cyclical conveying movement of the second chain conveyor 33 comes each pair of their on accordingly speaking webs not shown run the actuating rollers 47 needle plates 43 held in this position exactly aligned to stand above the stamp 60 . By a small relative movement of the stamp 60 with respect to the facing, the position shown in FIG. 9 taking two needle plates 43 , the pre-assembled stretcher handle 3 is impaled with its two reinforcement pockets 10 on the needles 46 of the two needle plates 43 and thus safely taken over.

Synchronized with acquisition of a carrying handle 3 of the lifting cylinder has a zoom out on the feed conveyor 50 folding box 1 so far raised 53 that it is inserted between an aligned on them retaining element pair 37, without, however, so far the now downward, the prefabricated handle 3 carrying To reach needle boards 43 ( Fig. 7, left position of the folding box 1 ).

In the next cycle step of the second chain conveyor 33 , the two holding elements 37 take the folding box 1 with them and move them from the lifting ram 53 to the first runway section 55 , which is at the same height and on which it then comes to a gluing station 600 ( FIG. 7) of the two opposite the side walls 4, 5 of the folding box 1 ( Fig. 1) for the subsequent attachment of the reinforcing tabs 10 and the handle end portions 12 required glue applied. During this transport movement, the actuating rollers 47 of the two associated needle plates 43 are moved into two laterally fixed pivoting switches 61 , which increasingly pivot the two pivoting levers 41 downward about their longitudinal parallel pivot axes 42 in the course of the further transport movement, as shown in FIG. 8 by arrows 63 is indicated. By appropriate design of the swivel switch 61 it is achieved that the two needle plates 43 are in the substantially vertically aligned position of FIG. 8 when the folding box 1 from the holding elements 37 on the second Rollbahnab section 56 ( Fig. 7) is transported. And it has arrived there, is triggered with the second Kettenför which 33 synchronized lifting device 57, which presses the folding box 1 upwards against a stationary pressure plate 64, with the result that the carrying handle 43 the ends held by the two needle plates 43 accurately U- folded in a shape and tight to the top wall 7 and the two side walls 4, 5 of the folding box ( Fig. 1) is applied.

By two stamps 65 , the z. B. are similar to the stamps 92 of FIG. 13, the handle ends with the reinforcing tabs 10 are stripped from the needle plates 43 and pressed directly onto the side walls 4 , 5 of the folding box 1 .

In the further course of the conveying movement, the pivot lever 41 are guided over the pivot switches 61 back up to the starting position in FIG. 8 (upper strand of the trans port chains 36 ). In a next station - while the chain conveyor 33 is stopped according to the cycle - the stretcher gripping the stretcher with the reinforcing tabs 10 is pressed against the folding box 1 again by appropriately designed further punches 65 in order to increase the safety of the adhesive connection that it produces. This additional station can also be omitted if necessary.

The finished folding box, which now has the status according to FIG. 1, is placed on the output conveyor track 59 and transported away from it.

The second embodiment shown in FIGS. 10 to 15, the handles for attaching the pre-assembled stretcher to the flat-lying folding box blanks 2 of FIG. 5, is constructed in principle similar to the above-described first embodiment according to FIGS. 6 to 9. The same parts are therefore provided with the same reference numerals and are not explained again.

In the pre-assembly station I for the straps 3 are cut from the drum 18 in the direction 19 strip-shaped Kartonma material by the cutting device 20 the length of individual handle 3 corresponding pieces of material 21 , which in turn placed on the first chain conveyor 23 and of its grippers 25 are cyclically transported at predetermined intervals in the transport direction 22 . The straight pieces of material 21 are first carried out through the two folding switches 29 a, in which they are converted into an approximately U-shaped shape in successive steps to produce the Z-fold 13 b according to FIG. 4. Embossing lines corresponding to the folded edges 14 , 15 ( FIG. 4) were previously pressed in by embossing devices 26 .

The thus pre-folded pieces of material 21 are introduced after passing through the folding switches 29 a in a station 70 , in which the reinforcing tabs 10 are applied to the end regions 12 of the pieces of material 21 . As can be seen in particular from FIG. 11, in this station 70 a circular table 71 which can be stepped cyclically about a horizontal axis of rotation is arranged, which on its circumference at an angular distance from the individual work stations has arranged holding means for individual reinforcing tabs 10 . On this, for example, pneumatically working holding means from the magazine 27 in a first work station each a reinforcing tab 10 is given, which is provided in the next work station at 72 by a stamp with the groove-like Ver recess 11 ( Fig. 4), whereupon it in the subsequent work station is seen by the gluing device 28 with a glue application ver.

The so finished embossed and glued reinforcing tab 10 is then pressed at 73 onto the two correspondingly supported end areas of the tactically advanced and correctly held pre-folded handle 3 , which is finally transferred to the transfer point 17 in the further course of the clock movements of the first chain conveyor 23 , where the prefabricated handle 3 is passed to the second chain conveyor 33 .

The also in cycles and synchronized with the first chain conveyor 23 working second chain conveyor 33 is arranged horizontally ( Fig. 11). The upright folding box blanks 2 are fed individually upright to him in an orientation parallel to the conveying direction 34 . The Faltschachtelzu sections are removed to from one of the supply conveyor 50 a advanced stack 74 by means of a the folding box blanks 2 51 (10 Fig.) Individually in the direction of arrow suction removal device 75 and in a by arrows 76 (Fig. 12) indicated movement to the Lifting ram 53 ( Fig. 11) applied, by which they are held by the suction cups 75 a of the pneumatic removal device 75 - in the direction of the arrows 54 upwards towards the lower run of the second chain conveyor 33 . The second chain conveyor 33 in turn has correspondingly designed holding elements 37 a, of which only one is indicated in Fig. 11 for each folding box blank 2 , and which are designed such that they act on the one hand as a driver and on the other hand the upright folding box blank 2 is attached backs up between them.

The holding elements 37 a are again receiving and pressing means for the pre-assembled carrying handles 3 assigned. This receiving and pressing medium have, as can be seen in particular from FIGS . 13 to 15, here also two pivot levers 41 a, b, which are connected to corresponding, with the two conveyor chains 36 of the second chain conveyor 33 connected bearing parts 76 in the longitudinal direction of the chain conveyor facing pivot axes 42 are pivotally mounted. The two pivot levers 41 a, b have a different length. They both carry at their free ends a needle plate 43 with pointed nails or needles 46 and an associated plate 44 , on its opposite side on the swivel arm 41 a an abutment element 77 is welded. Each of the swivel arms 41 a, b is provided with an actuating roller 47 , the associated bearing element of which is designated 48 a or 48 b. By appropriate design of the guide roller interacting with the loading roller 47 , each pivot lever 41 a, b can be pivoted by approximately 90 °, as is illustrated in FIG. 14 by means of the two indicated positions of the operating roller 47 , of which the upper, only partially indicated position 47 'corresponds to the horizontal orientation of the pivot lever 41 a, as can be seen from Fig. 13. It is determined by a stop 400 .

The plate 44 of the needle plate 43 is, as shown in FIG. 15, formed arm-like in such a way that it lies with a part next to the pivot lever and with its three needles 46 securely grips the reinforcing tab 10 and the carrying end.

At the other end, the pivot lever 41 a or b is rotatably mounted on a pin 79 ( FIG. 15) containing the pivot axis 42 via roller bearings 80 . It is under the action of a spring 81 placed on the bolt, which strives to keep the pivot lever 41 a or b in the horizontal orientation shown in Fig. 13 above. The bolt 79 is in turn received in a bearing block 82 ; a threaded pin 83 allows attachment to the respective bearing part 760 of FIG. 13.

As already mentioned, the function is basically similar to the embodiment according to FIGS. 6 to 9:

During its cycle movement, the second chain conveyor 33 brings the paired swivel levers with downward-pointing needle sinkers 43 - as indicated in FIG. 13 above - in pairs one after the other to the transfer point 17 ( FIG. 11). Here come the two needle plates 43 of the springs 81 ( Fig. 15) horizontally aligned pivot lever 41 a, b on the two supports 60 on lying reinforcement tabs 10 of the first chain conveyor 23 each brought up to the ready-made handle 3 . Two contact stamps 89 ( FIG. 13) of the transfer device 17 arranged at this point are actuated; they press the needles 46 of the needle plates 43 into the material of the underlying reinforcement tabs 10 over the abutment, so that they are firmly adhered to who when the pressure pistons 89 return to their rest position. The pre-assembled carrying handle 3 hanging on the two needle plates 43 is now transported further in accordance with the cycle. In the next station, a folding box blank 2 , aligned in the conveying direction to the right, is fed to the respective holding elements 37 a in the manner already explained ( FIG. 11, left folding box blank 2 ). The folding box blank 2 , which is initially still at a distance from the horizontal pivot levers 41 a, b, is taken along by the holding elements 37 a and placed on a support plate 91 of the lifting device 57 corresponding to the runway section 56 of FIG. 7 after it had previously passed the glue station 600 . At the same time, the actuating rollers 47 of the two pivot levers 41 a, b are retracted into the pivot switches 61 , with which they are pivoted increasingly downwards until they have finally reached the vertical position indicated by dashed lines in FIG. 13 for the longer pivot lever 41 a. During this pivoting movement of the pivot lever 41 a, b, the handle 3 held by the Nadelpla 43 is folded U-shaped over the adjacent edge of the folding box blank 2 . The lifting device 5 pushes the folding box blank upwards so that the handle 3 is snugly cut to the opposite sides of the folding box 2 . This edge is designated 92 in FIG. 5. Because of the design of the folding box blank 2 , the two reinforcement tabs 10 must be attached at different distances from the edge 92 . This is achieved by the different length of the two pivot levers 41 a, b.

And the two pivoting levers 41 a, b with the Nadelpla routines 43 in its vertical position has passed and the folding box blank 2 has been fully depressed by-shaped top of the U carrying handle 3, of the folding box blank 2 are two sides angeord designated, opposing pressing devices 92 for Effect, for example, a lever mechanism 93 ( Fig. 13) are mechanically driven clockwise and were moved from a lower rest position to their upper working position, such that they could not hinder the movement of the pivot lever 41 a, b. You press the reinforcing tabs 10 of the counter-bearings 77, 94 on the other side according to supported Faltschachtelzu-section 2, and streak the carrying handle with the United reinforcing tabs 10 of the back contrasting needle sinkers from 43rd

The pressing device 92 has a fork-shaped fitting 78 which is arranged on a longitudinally displaceable stamp and which engages or engages around the needle plate 43 (see FIG. 15) and is supported directly on the reinforcing strap and the handle end.

And the adhesive has set, which is now more finished folding box blank 2 is brought to the carrying conveyor 59 from a, on which the bearing their carrying handles 3 folding carton blanks 2 are stored in an imbricated manner one above the other (Fig. 10). When moving to the discharge conveyor 59 a, the actuating rollers 47 of the pivot levers 41 a, b emerge from the pivot switches 61 , so that the springs 81 can position them again in the horizontal position ( FIG. 13 above).

In the initial state shown in FIG. 1, in which the handle 3 is held tightly against the top wall 7 of the folding box 1 , the handle can simultaneously act as a closure element for the box. This means that gluing to this closure side is no longer necessary in every case.
