Abstract

In order to increase the capacity of a drying turret (13) for cigarette packs (10), units made up of a plurality of pockets (14, 15), which are moved alternately into a charging position and an emptying position, are arranged on the circumference. This increases the residence time of the packs (10) in the drying turret (13) in accordance with the number of pockets (14, 15) per unit.

Description

  The present invention is preferably a conveyor for the movement of packs (in the shape of a rectangular parallelepiped) with a plurality of pockets for storing a plurality of packs arranged in close proximity and perpendicular to the direction of movement. In particular, it relates to a dry turret for cigarette packs. In this case, in the loading area, the pack can be loaded into the pocket by axially parallel movement, and at the same time, on the opposite side, the pack can be loaded from this pocket.

  A preferred field of application of the present invention is the drying turret as a unit of cigarette pack equipment. The pack comprises folding tabs connected to each other by an adhesive following the folding process. The bonded area of the pack requires a dwell time in order for the adhesive to be sufficiently stiff or rigid. And the shape of the pack is fixed to the rectangular parallelepiped shape during the staying time. For this purpose, a dry turret is used.

  It is known to use dry turrets in various ways for cigarette packs. The drying turret according to DE 4300149 is continuously rotatable. The pockets arranged within the range and oriented parallel to the axis are arranged for storing three packs each. At the end, the pack is loaded into the pocket and simultaneously pushing the facing pack.

  For higher power packing machines, the cigarette pack dwell time is not sufficient with a conventional drying turret to ensure a stable folding tab adhesive bond. It is not taken into account that such an increase in the size of the drying turret occurs from the bottom surface.

German Patent Application No. 4300149

  The object of the present invention is therefore to significantly improve the production capacity of cigarette packs, in particular dry turrets, without increasing the dimensions and maintaining the normal manufacturing process.

  To solve the problem, a conveyor or drying turret according to the invention is arranged on the conveyor, in particular in the area of the drying turret, in which a unit with at least two pockets which can be moved, in particular rotatable, is arranged. The at least two pockets reach an outward loading or unloading position by either moving or rotating the unit.

  In particular, a conveyor composed of a drying turret includes a unit composed of two or more pockets. The two or more pockets are pocket support portions, and by rotation of the unit, the pockets of the unit are directed outwardly or one after another toward a relatively continuously rotating drying turret. And / or directed to an unloading position. Without increasing the size of the drying turret, the production capacity increases corresponding to the number of pockets per unit. The pack is configured into a provided pocket during multiple rotations of the drying turret. At this time, supply and removal from the pocket of the pack are performed by a conventional method.

  The rotation of the unit at about 180 ° (in the case of two pockets per unit) or 120 ° (in the case of three pockets per unit) is either by a fixed adjusting device, in particular by a cam mechanism. The rotation of the drying turret is also performed in a predetermined rotation area.

  Further details of the invention relate in particular to the shape of the drying turret and the transmission mechanism. Embodiments of the invention will be described in more detail later on the basis of the drawings.

A portion of a cigarette pack device is shown in a schematic side view. As a detail of the pack device of FIG. 1, a partial region of the drying turret is shown in an enlarged view. The vertical section of the pocket or the area of the pocket unit according to section III-III in FIG. 2 is again shown in an enlarged view. Fig. 4 shows a cross section of the pocket or the pocket unit adjusting device corresponding to the cross section IV-IV in Fig. 3. FIG. 5 shows a cross section taken axially with respect to FIG. 4 in the adjusting device region along the section VV in FIG. Fig. 5 shows a cross section by a pocket unit corresponding to a cross section VI-VI in Fig. 3 or an axial cross section. FIG. 7 shows a view corresponding to FIG. 6 for another embodiment of a pocket unit. The details of the actuating device, the roller star, are shown in the drawing. 9 shows details in the cross section of FIG.

  The drawings are useful for understanding the operation and processing of the rectangular parallelepiped pack 10, ie, cigarette pack. Specifically, the pack 10 becomes a problem when implemented as a soft container. The pack 10 is made in the area of the folding turret 11 and is then taken over by an intermediate conveyor, i.e. a transfer turret 12, which transfers the pack 10 into a further turret, i.e. a drying turret 13. Hand over to harden the adhesive bond. This is configured in a special way.

  In particular, the drying turret 13 has a problem that it accepts a larger number of packs 10 for a longer period of stay, stabilizes the shape of the rectangular parallelepiped shape of the pack 10, and hardens or dries it during the period of adhesive bonding. is there. The drying turret 13 is provided with a number of pockets 14, 15, 16 around the drying turret for this purpose. The pockets 14-16 are configured beside the rotational direction of the drying turret and parallel to the axis. The pockets 14-16 correspond to the size of the pack 10, that is, correspond to the bottom wall 17 or the top wall 18 and are configured in a sleeve shape having a rectangular cross section. In the pockets 14-16, a dense row of packs 10 is formed or held, in which case the packs 10 are in direct contact with each other, i.e. the bottom wall 17 and the top wall 18 are connected. I have. The packs 10 are individually loaded into the pockets 14-16 through the load openings 19. This action pushes the pack row of pockets 14-16 as a whole, so that at the same time, with the discharge opening 20 on the opposite side, the pack 10 is removed from the corresponding pocket 14-16, in particular an external film pack. In order to obtain, the pack device is discharged and movable.

  The drying turret 13 passes through several devices during continuous rotational movement. In the area of the delivery device 21, the pack 10 is placed from the transfer turret 12 into the load opening 19 of the adjacent pocket 14-16. In addition, a support device, that is, a support plate 22 that is aligned with the load opening 19 is provided. The delivery of the turret 12 is performed in the subsequent turret 13, which is the method described in German Patent Application Publication No. 4300169.

  The pack 10 placed on the support plate 22 is loaded into the pockets 14-16 by the pusher 23 during the continuous rotation of the drying turret 13. Any pocket 14-16 positioned in the outer region of the drying turret 13 comprises a pusher 23 that rotates with the drying turret 13 and is operable by an operating rod 24, ie the pocket 14 Operable in the -16 direction and back to the exit position. The support plate 22 is divided in the center for passage of a pusher 23 arranged in the center for the support plate 22 or the load opening 19 or a bridge coupled to the operating rod 24, or , Slits are provided.

  Opposite, i.e., in the region of the discharge opening 20, a pack that discharges from the pocket 14-16 is placed on the stage 25. Here, the complete pack 10 with regard to adhesive bonding is taken out and transported to the moving path 26 (in particular defective packs) or delivered to the removal conveyor 27.

  When the pack 10 is loaded in the pockets 14, 15, 16, a band seal (taxed or stamped) is attached in the region of the top wall 18. This is prepared by the banding 28 being placed in a U shape around the top wall 18 when loading in the pockets 14, 15, 16 in front of the load opening.

  The pack 10 remains in the pocket 14-16 for several revolutions of the drying turret 11 depending on the axial dimension of the pocket 14-16. In order to increase the staying time of the pack 10 in the pocket 14-16, in particular, without changing the dimensions, the pocket 14-16 is arranged in the drying turret in a special way. Several pockets 14-16 are made up of units, which alternately have one, another or third pockets 14, 15, 16 leading to the loading position, ie the folding turret 11 It is configured to be located in the outer region. The pockets 14, 15, 16 belonging to one unit are arranged on a common support. This is arranged to be operable, i.e. rotatable in the outer region of the drying turret 13. This comprises support members 30, 31 in the axial direction and a rotary bearing for the rotatable bearing of the support 29 is provided at the end opposite to each other. The support member 31 disposed in the discharge opening 20 is formed of a mold body, and the support body 29 includes a journal 32 and is rotatably supported. Opposite the support 29 is provided with an operating rod or operating shaft 33. The operation shaft 33 is rotatably supported by the support member 30 and can be rotated and operated by an operation mechanism. In this case, the unit composed of the support 29 and the pockets 14, 15, 16 rotates in the same manner corresponding to the drying turret 13.

  The pocket unit can be variously configured. The first embodiment consists of two pockets 14, 15 which are connected to a common support 29, opposite to each other. The support 29, or (imagine) the axis of rotation, is arranged identically in the center between the pockets 14 and 15. The rotation of the unit or of the support is such that the pocket 15 located axially inside according to FIG. 6 has moved exactly to the position of the pocket 14, ie to the outer region of the drying turret. The support 29 with the pockets 14, 15 is then rotated by a difference of 180 °. In particular, after any rotation of the folding turret 11, a position exchange of the pockets 14, 15 is performed, so that they are alternately loaded and the pack 10 is unloaded.

  The pocket unit has more second pockets. In the case of the embodiment according to FIG. 7, three pockets 14, 15, 16 having the same angular spacing are provided on a common support 29. With individual support rotations of approximately 120 °, the pockets 14, 15, 16 in turn reach the axially outer loading position. In the case of the example of FIG. 6, the capacity of the drying turret is doubled, and in the case of FIG. 7, it is three times that of the embodiment with one conventional pocket.

  The pocket unit or support 29 is rotated once at about 120 ° or about 180 ° by the transmission mechanism during the rotation of the drying turret. The transmission mechanism is fixed and arranged in the upper region of the drying turret 13 rotating on an upright plane (FIG. 4). Any pocket unit or support 29 is provided with a rotating operation period, and the operation period acts on the operation shaft 33. In the case of the present embodiment, the operation transmission mechanism is constituted by a cam mechanism. The operating mechanism is a rotating body or a roller star 34, and the roller star 34 is closed over a wide range, and the sleeve-shaped housing 35 rotates in accordance with the rotation of the drying turret 13. At that time, during the entire rotation of the drying turret 13, a half rotation or a partial rotation is transmitted to the pocket unit.

  The roller star 34 is provided with operating means, that is, rollers 36, 37, 38, 39, 56, 57. In this case, two roller pairs are important. The roller pairs are arranged on different planes of the roller star 34 and are provided with cam tracks. The rotor star 34 or support for the roller is arranged in the center of the pocket unit, i.e. is connected to the roller at the end of the operating shaft 33.

  The roller star 34 or this support consists of two support disks 58, 59 which are spaced apart from one another. The support disks 58 and 59 face each other in the axial direction, form an intermediate space 60, and are fixed and coupled to each other via a central shaft portion 61. Intermediate rollers 36, 37 are arranged in the region of the intermediate space 60 and here both are connected to a support disk, ie a support disk 58 arranged away from the pocket. Further rollers, one 38, 39 and the other 56, 57, are rotatably bearing on the opposite sides of the support disks 58, 59, and with respect to the rollers 36, 37. It is shifted by about 90 °.

  The rollers 36-30 and 56, 57 travel on the cam track and travel in pairs. The cam track is a portion of the housing 35 that is configured correspondingly and advances around. The rollers 38 and 39 on the outer side are arranged on the first cam track, that is, on the outer cam 41. Opposing rollers 56, 57 travel on the second cam track, ie, the inner track 42. Mainly, the circular cam tracks 41 and 42 have the same diameter and exist on a common circular plane. A third cam track on which the rollers 36 and 37 are arranged, that is, the intermediate cam 43 is arranged in a space between the cam tracks 41 and 42 and has a smaller circular diameter.

  The rollers are arranged on the roller star 34 in a special relative position in order to be effective in the area of the rotating device or in the rotation area of the pocket unit (FIG. 4). The rollers 36 and 37 are disposed on the opposite sides of the roller star, and on the lateral side of the common center. On the one hand, the rollers 38 and 39 and on the other hand 56 and 57 are similarly arranged on the opposite sides, but on the shifted side. As is apparent from FIG. 8, the roller 38 that is forward in the rotational direction of the roller pair 38, 39 is in contact with the outer cam 41 that is configured, while the opposite roller 39 is lifted from the outer cam 41. At the opposite relative position, the roller 56 forward in the direction of movement is lifted from the arranged inner track 42, while the rear roll 57 is in contact with this inner track 42.

  In order to carry out the rotational movement of the support 29, the cam mechanism has a characteristic shape in the rotating device region. Both the outer cam 41 and the inner cam 42 are provided with a recess 44, that is, a recess that is recessed radially inward and rounded. In the same place, the cam track 43 is provided with a hill 45, that is, a bulge facing outward in the axial direction. The hill 45 is provided with a flat portion 62 on the outside, and the flat portion 62 prevents the shaft portion 61 of the roller star 34 from being stranded on the hill 45 on the same surface. In the case of the roller 38 in front of the rotational movement, the recess 44 is first entered. At the same time, the roller 37 rides on the hill 45. Thereby, the rotation of the unit occurs counterclockwise (FIG. 4). The function of the cam mechanism is such that half rotation occurs when the roller 38 reaches the deepest location of the recess 44. In the case of continuous rotational movement, the roll 38 reaches the outer cam 41 for this device and is forward in the direction of rotation of the drying turret 13. Further, the roller 36 maintains contact with the cam track 43 after overcoming the height 45, and at the same time, the roller 37 is lifted from the cam track 43. Furthermore, changes occur with respect to the roller pairs 38, 39 and 56, 57. One roller 39, 56 is in contact with the arranged cam tracks 41, 42. With the rollers arranged in this pair, a very stable position of the pocket unit occurs during the rotation, and likewise a precise rotational movement occurs in the area of the rotating part.

  A further feature is the delivery of the pack 10 in the drying turret 13. A solution similar to the solution according to DE 43 00 169 is that at the starting face of the pocket 14-16, there is a storage area for the pack 10, ie adjacent to the load opening 19 and operable. The support is effective and has been described until it is taken over from the transfer turret 12 and loaded into the pocket 14-16. This support is a grip arm 46 effective on the two sides of the pack 10. Some of the grip arms arranged side by side are attached to a common arm holder 47, and the arm holder 47 is rotatably supported. This rotational movement is transmitted from the operation rod 48, and this operation rod 48 is arranged adjacent to the operation shaft 33. The rotation operation of the operation rod 48 and the rotation operation of the grip arm 46 are caused by a transmission device, and the transmission device is configured as a cam mechanism. The detection rollers 49 and 50 travel on a cam track, that is, the inner track 51, and they form a continuous circle around the casing 35. As is apparent from FIG. 5, the detection rollers 49 and 50 on which the operation rods 48 for the respective arm holders 47 are arranged are pressed against the cam track or the internal track 51 by a spring 52. This trajectory is formed through the detection rollers 49 and 50 so that a turning operation for opening and closing the grip arm 46 or for grasping and releasing the pack 10 acts. Each of the detection rollers 49 and 50 is coupled to the operation rod 48 via a turning arm 53.

  The configuration of the folding turret 11 is adapted to the operable pockets 14, 15, 16 or pocket unit. The support members 30, 31 are provided with an inner wall 54 which advances in the circumferential direction in a recess which moves to the periphery, for the reception of pocket units which are bearing against each other at a slight distance. For sufficient support and operation of the operating shaft 33, this is used in addition to the support member 30 with further spaced support walls 55. The support wall 55 and the housing 35 are connected.

The power of the pocket unit is also implemented in a further way. Therefore, every pocket unit has its own power, for example, a servo motor.
