EP0356654B1 - Device for supplying (package) blanks to a packaging machine - Google Patents

Description

The invention relates to a device for feeding stacks of pack blanks to a blank magazine of a packaging machine, in particular for producing hinged boxes for cigarettes, the stacks being able to be fed to an emptying station in open containers.

For the production of certain packs, for example folding boxes (hinge-lid packs) for cigarettes, it is necessary or customary to provide the packaging machine with blanks produced in another way as a stack of blanks. These blanks are usually made by punching in a paper mill. The packaging machine comes with one (or more) blank magazine equipped into which the cut stacks are fed. The individual blanks for folding the packs are removed from the underside of the blank magazine.

The increasing performance of packaging machines is causing problems with the proper supply of packaging material. This applies above all to the cut stacks, which are difficult to handle. So far, these have mainly been handled manually, namely entered in batches in the blank magazine.

From EP-A-0 258 597 it is known to feed blanks on a container-like stacking pallet to a packaging machine. The pallet itself must be loaded and can be moved close to the floor.

The invention is based on the object of proposing a device by means of which the handling of the blanks or stack of blanks in the area of the packaging machine is facilitated and becomes more efficient with the extensive exclusion of manual use.

To achieve this object, the device according to the invention is characterized by an overhead conveyor for feeding the containers designed as cassettes filled with stacks of blanks, a first vertical conveyor for taking over the full cassettes from the overhead conveyor, and a cassette conveyor for taking over the full cassettes from the first vertical conveyor in the area of a feed station and for further conveyance to the emptying station for the removal of stacks of blanks from the cassettes and for transfer to the blank magazine, and by a second vertical conveyor for the acceptance of empty cassettes from the cassette conveyor in the area of a removal station and for feeding the cassettes to the overhead conveyor.

Manual use is not necessary with the new conveyor. The cassettes are loaded centrally, preferably at the place where the blanks are produced. The cassettes are in a sealed position on the cassette conveyor, so that the former at the same time forms a receivable memory due to the length.

The cassette conveyor is preferably arranged on the back of the packaging machine, approximately parallel to the longitudinal center plane of the same. In the area of the emptying station, the stacks of blanks are successively removed from the cassettes by an upward movement.

The path of movement of the blank stacks is in a level above the packaging machine transversely to this or transversely to the cassette conveyor to the front or to the front area of the packaging machine. Here, the blank stacks are preferably transferred to two blank magazines as required.

The emptied cassettes are transported on the cassette conveyor beyond the emptying station and either loaded on pallets or returned to the circulation conveyor circuit.

The cassettes are expediently designed such that a plurality of emptied cassettes can be nested inside one another in a space-saving manner, so that the space requirement is small when transported back to a filling station.

Further features of the invention relate to the design and arrangement of the cassette conveyor as well as conveying elements connected to it for the transport of the blank stacks up to the blank magazines. Furthermore, the invention is concerned with the mechanized feeding of the cassettes to the cassette conveyor and with the removal of the empty cartridges.

The exemplary embodiment shown is concerned with the handling, in particular the transport, of (pack) blanks 20 in the area of a packaging machine 21. The blanks 20 shown are used for producing hinged boxes (hinge-lid packs) for cigarettes.

The blanks are produced outside the packaging machine 21, in particular in a paper mill, and stacked, namely delivered as a blank stack 22. The object is to feed blanks 20 or blanks 22 of blanks to the packaging machine 21 to a sufficient extent. In the exemplary embodiment shown, the packaging machine 21 is equipped with two such blank magazines 23, 24. These are designed as an upright or slightly inclined shaft with a U-shaped cross section. On the underside, the blanks 20 are removed from the blank magazines 23, 24 by a removal member, in the present case by a dispenser 25 of a generally known type. The blanks 20 or blank stack 22 are fed to the blank magazines 23, 24 from above.

The core of the device for conveying and handling the blank stacks 22 are containers, namely cassettes 26. In each of these, a plurality of blank stacks 22 are accommodated side by side. In the present case, the cassettes 26 consist of a bottom wall 27, on which the cut stacks 22 rest, and of upright walls or wall elements. These are webs 28 connected to the bottom wall 27. These are arranged on the bottom wall 27 in such a way that several, namely in the present case four chambers 29 are formed side by side. The chambers 29 are separated from one another by webs 28. There is a blank stack 22 in each chamber 29.

The cassette 26 is open at the top, and consequently also the chambers 29.

The bottom wall 27 is provided with rectangular openings 30. On the one hand, these allow nested stacking of several empty cassettes 26 for space-saving removal thereof. On the other hand, the openings 30 are formed and arranged approximately in the central plane of the chambers 29 so that lifting elements can pass through the bottom wall 27 from below in order to lift the stack of blanks 22 out of the chambers 29. The openings 30 are rectangular in cross section.

The cassettes 26 are filled with the cut stacks 22 at a suitable point, in particular in the paper mill, and then fed to the packaging machine 21. This is assigned a cassette conveyor 31 on which the cassettes are placed. The cassette conveyor 31 is designed as a belt conveyor with, in the present case, two conveyor belts 32, 33 arranged at a distance from one another (e.g. FIG. 6). The cassettes 26 stand with their edge regions on the conveyor belts 32, 33, so that the openings 30 arranged at a distance from the edge of the bottom wall 27 are exposed.

The cassette conveyor 31 runs as an elongated conveying member on the back of the packaging machine 21 directly next to it and approximately parallel to the (imaginary) longitudinal center plane thereof. At one end of the cassette conveyor 31, a loading station 34 is formed for placing the individual cassettes 26. At the opposite end there is a removal station 35 for empty cassettes 26. In an area facing this removal station 35, an emptying station 36 is formed, in which the stack of blanks 22 can be removed from the cassette 26 one after the other. The area from the loading station 34 to the emptying station 36 forms a memory for Cassettes 26 and blank stack 22 with considerable capacity.

The (filled) cassettes can be fed to the loading station 34 on pallets or other carriers and can be placed on the cassette conveyor 31 by hand. However, the solution shown in FIGS. 2 and 3 with automatic transport of the cassettes 26 is more advantageous. A circulating conveyor is installed above the packaging machine 21, in particular on a building ceiling. This consists of suspended rails 37 and roller carriages 38 which can be moved on the rails 37. Each roller carriage 38 is equipped with a material carrier 39 which is suitable for receiving a cassette 26 in each case. This "overhead" conveyor system is preferably designed analogously to the conveyor system of DE-A-3827917 patent application (published on December 21, 1989).

In the area of the packaging machine, vertical conveyors 40, 41 are each arranged in the area of the loading station 34 and the removal station 35. These are designed analogously to the vertical conveyors of DE-A-3827917 mentioned. Cassette holders 43, 44 can be moved up and down on an upright support column 42. Each cassette holder 43, 44 is designed so that a cassette 26 on horizontal support members, e.g. Support rods, recording takes place and can be promoted next to the support column 42 downwards or upwards. The relative position of the vertical conveyors 40, 41 to the roller carriages 38 and their material carriers 39 on the one hand and to the cassette conveyor 31 on the other hand is selected such that the transfer of the cassettes 26 from one conveyor to the other takes place automatically by relative movement, specifically in the patent application DE -A-3827917 described manner.

Filled cassettes 26 are accordingly automatically placed on the cassette conveyor 31 in the area of the feed station 34. while emptied cassettes 26 are also automatically taken over in the removal station 35 by the cassette holder 44 and are conveyed upwards for being carried along by a roller carriage 38 or by the material carrier 39.

The blank stacks 22 removed from the cassettes 26 in the emptying station 36 are first conveyed upward, moved in a plane above the packaging machine 21 transversely to the latter or transversely to the cassette conveyor 31 and finally fed to the blank magazines 23, 24 by sideways movement (FIG. 8th).

For emptying the cassettes 26, they are positioned exactly in the emptying station 36 with respect to a stack lifter 45. For this purpose, stops 46 are formed on the underside of the bottom wall 27 of the cassette 26, which stop against a positioning stop 47 that can be inserted into the path of movement of the cassette 26 to run. In the embodiment shown, the stops 46 are formed as a rear boundary of molded-in depressions 48 in the bottom wall 27. To determine the exact position of the cassette 26, a plurality of, namely four positioning stops 47 are arranged on a stop wheel 49 which is driven to rotate in cycles. The cassette 26 is aligned in such a way that one chamber 29 is centered on the stack lifter 45. After a stack of blanks 22 has been lifted out, the cassette 26 is transported further by one cycle until a subsequent positioning stop 47 bears against the subsequent stop 46 of the cassette 26 when the stop wheel 49 is rotated through a corresponding quarter.

The stack lifter 45 here consists of two plungers 50 which can be moved up and down together. In the starting position (FIGS. 5, 6), these are located below the cassette 26 or below a conveying run of the cassette conveyor 31 and between the two conveyor belts 32, 33 (Fig. 6).

The plungers 50 are aligned with the cassette 26 such that they can pass through two openings 30 in the bottom wall 27 of the cassette 26, in the middle of a chamber 29. The plungers 50 have a cross section which is matched to the opening 30. By moving the plunger 50 upward, the blank stack 22 is grasped on the underside and lifted out of the cassette 26 via the open top thereof.

The plungers 50 only perform a limited stroke movement, namely up to a position of the blank stack 22 above the cassette 26 (FIG. 7). In this position, the blank stack 22 is taken over by a high conveyor 53 and moved further upwards.

In the present exemplary embodiment, the plungers 50 are attached to a common plunger carrier 51, which in turn can be moved up and down on an upright guide column 52 connected to the packaging machine 21.

In the present case, the high conveyor 53 consists of pivotable pawls 54, each of which has lugs 55 on the long sides under the blank stack 22. The pawls 54 acting on both sides of the blank stack 22 are moved upwards together. In the present case, for this purpose, each pawl is attached to a sliding sleeve 56, which by means of organs not shown, e.g. Pressure cylinder, up and down along an upright guide rod 57 is movable. During the upward movement, the blank stack 22 is carried up to a transverse conveyor plane 58.

The upright blank stacks 22 become the front in the transverse conveyor plane 58 above the packaging machine 21 or conveyed to a front area thereof, specifically by a cross conveyor 59.

The cross conveyor 59 here consists of a horizontal slideway 60, on which the stack of blanks 22 stand and are shifted in cycles. For the conveyor drive of the blank stacks 22, the cross conveyor 59 is designed as a clock conveyor with a plurality of drivers which each engage and move on the rear side of the blank stack 22. These are designed here as upright driver rods 61. The height of the same is adapted to the height of the blank stacks 22, so that they are covered over the entire height.

All driver rods 61 of the cross conveyor 59 are actuated simultaneously by a common drive. This consists of a common push rod 62 which is arranged next to the movement path of the blank stacks 22. This is driven back and forth, in each case by one conveying cycle, namely from the rear starting position drawn out in FIG. 8 to the front end position shown in broken lines. During this conveying movement, the entraining rods 61 are moved into the entraining position, approximately centrally at the rear of a blank stack 22. In the present exemplary embodiment, four blank stacks 22 are gripped by the cross conveyor 59 and moved on by one cycle. Each time, a stack of blanks 22 fed by the high conveyor 53 is also detected and conveyed onto the slideway 60. For the return movement of the cross conveyor 59 into the starting position (solid lines in FIG. 8), the driver rods 61 are previously withdrawn from the position on the rear of the blank stack 22 and pivoted into a lateral position next to the path of movement of the blank stack 22.

For this purpose, the driving rods 61 are on a swivel arm 63 is mounted above the plane of movement of the blank stack 22. The swivel arm 63 is in turn connected to an upright rotating rod 64 which is rotatably attached to the push rod 62. The pivot rods 64 are pivoted together, in each case via a pivot bracket 65, which is arranged at the lower end of the pivot rod 64, below the push rod 64. This in turn is located in a plane below the slideway 60. The pivot tabs 65 can be actuated in a suitable manner be, for example by pressure cylinder.

The driver rods 61, which are only supported at the upper end, namely connected to the swivel arm 63, can be extended down to below the transverse conveying plane 58 so that the blank stack 22 is reliably grasped over the entire height. For this reason, the slideway 60 is provided with a longitudinal slot 66 in which the lower ends of the driving rods 61 run during the conveying cycle. In the slideway 60, arc slots adjoining the longitudinal slot 66 are formed, which enable the driving rods 61 to exit from the longitudinal slot 66 when the driving rods 61 are pivoted into the position for the return movement of the push rod 62. The arch slots are not shown here for reasons of clarity.

The cross conveyor 59 transports the blank stacks 22 in cycles to a cross distributor 67. This has the task of transporting the batches of blanks 22 fed cyclically in the direction transverse to the cross conveyor 59 into a position in front of one or the other blank magazine 23, 24 and then handed over to the relevant blank magazine 23 or 24. The blank magazines 23, 24 are arranged above a plate-shaped folding turret 68 which rotates about a vertical axis in the present exemplary embodiment. The blank magazines 23, 24 are open on both sides of the cross conveyor 59 Side facing the front of the packaging machine 21. The blank magazines 23, 24 are U-shaped in cross section with side walls 69 and an end wall 70. The blank magazines 23, 24 are open at the top. On the underside is the already mentioned dispenser 25 as a removal member for the blanks 20. The blank magazines 23, 24 are arranged at a slight incline.

The cross distributor 67 contains a stacking pocket 71. In an approximately central position aligned with the cross conveyor 59, a stack of blanks 22 is conveyed into this at each conveying cycle of the cross conveyor 59. For this purpose, the stacking pocket 71 is open on the side facing the cross conveyor 59.

The blank stacks 22 are located in the stacking pocket 71 on a support base 72. In the exemplary embodiment shown (FIG. 9), the support base 72 is designed as a relatively narrow web which extends in the middle of the stacking pocket 71. There is an upright rear wall 73 on the support base 72, which is also designed as a relatively narrow structure (FIG. 9). Furthermore, the stacking pocket 71 is equipped with pocket side walls 74 on both sides of the blank stack 22.

The stacking pocket 71 as a supporting element for a blank stack 22 is mounted on a transverse guide 75. This consists essentially of a support rod 76 on which the stacking pocket 71 is slidably mounted with a rotary guide 77. By moving the rotary guide 77 on the support rod 76, the stacking pocket 71 can alternatively be moved in front of the end of the cross conveyor 59 or in front of one of the blank magazines 23, 24.

The stacking pocket 71 or a support unit consisting of the support base 72 and rear wall 73 can also be moved in the direction parallel to the cross conveyor 59.

This further movement of part of the stacking pocket 71 serves to feed a stack of blanks 22 to the blank magazine 23, 24. For this purpose, the rear wall 73 connected to the base 72 is displaceably mounted on a longitudinal guide via a bearing sleeve 78, namely on a longitudinal rod 79. This is (approximately) parallel to the cross conveyor 59. The longitudinal rod 79 is held by a support frame, namely by a support bracket 80.

To transfer a stack of blanks 22 to a blank magazine 23, 24, the stacking pocket 71 or its support base 72 with rear wall 73 is displaced in the direction of the blank magazine 23, 24 oriented toward the open side thereof, that is to say parallel to the cross conveyor 59. The pocket side walls 74 connected in the present case to the carrying guide 77 remain in the starting position.

The blank stack 22 is moved - with the support base 72 - into the magazine 23, 24. To transfer the stack of blanks 22, the base 72 - with the rear wall 73 - is tilted into an inclined position (solid lines in FIGS. 10 and 11). In this position, the blank stack 22 is aligned with the inclined position of the blank magazine 23, 24. By pulling back the support base 72 in the inclined position, the blank stack 22 is transferred to the blank magazine 23, 24, namely to a remaining stack 81 in the magazine 23, 24. The new blank stack 22 is therefore only transferred after the blank has been emptied -Magazin 23, 24 except for the remaining stack 81, which ends below the tray 72. The blank stack 22 which is released by pulling back the support base 72 overcomes a small drop height until it rests on the remaining stack 81. The stacking pocket 71 is then moved back into the upright position and moved in front of the cross conveyor 59 for receiving a further blank stack 22.

To carry out the described tilting movement of the blank stack 22 in the blank magazine 23, 24, the stack pocket 71 is mounted on a tiltable support frame 82. This consists of lateral, upright support legs 83. Their upper ends are connected to one another by the transverse support rod 76. The lower ends of the support legs 83 are pivotally mounted via a bend 84, namely via a pivot bearing 85 connected to the machine frame of the packaging machine 21.

The entire support frame described can therefore be tilted about the pivot bearing 85, specifically after the introduction of a blank stack 22 together with the support base 72 into a blank magazine 23, 24. The tilting movement here is approximately 10 °.

The support bracket 80 as a support member for the stacking pocket 71 is supported on the support frame 82 so that despite the displaceability of the support guide 77 on the support rod 76, the support bracket 80 acts as a cantilever arm. For this purpose, a cantilever arm 88 is connected laterally to the support frame 82, namely to the support legs 83. These act as rigid supporting elements. The free ends of the cantilever arms 88 are connected to one another by a transverse support rail 89. In this, the support bracket 80 is slidably supported, in the present case by a support roller 90, which is connected via an extension 91 to the top of the support bracket 80. The support bracket 80 can thus be moved with the stacking pocket 71 by moving the support guide 77 on the support rod 76 without twisting transversely to the cross conveyor 59.

The parts of the stacking pocket 71, namely the support base 72 and the rear wall 73, which are displaceably mounted with the bearing sleeve 78 on the longitudinal rod 79, are secured against rotational movements about the longitudinal axis of the longitudinal rod 79. In the embodiment shown (Fig. 9), a support leg 86 is attached to the side of the bearing sleeve 78, which with the free end runs in a guide 87. This is connected to the support guide 77 and extends in the direction of movement of the bearing sleeve 78. The end of the support leg 86 can be supported in the groove of the guide 87 with a roller (not shown).

By means of the cross distributor 67, the blank stack 22 received in a central position of the stacking pocket 71 is moved as required by transverse displacement of the stacking pocket 71 on the support rod 76 in one direction or one direction or the other according to the requirement of one or the other blank magazine 23, 24 and handed over to it in the manner described. The movement steps of the stacking pocket 71 are matched to the conveying cycle of the cross conveyor 79, in such a way that the emptied stacking pocket 71 is kept ready for the reception of a blank stack 22 in the extension of the cross conveyor 59.
