Definitions

  • the invention relates to a device for supplying packaging machines or the like, with packaging material which is made available as material webs wound in bobbins, wherein the bobbins can be removed one after the other and fed to a working spigot from a bobbin storage device, and the bobbin storage device above the working spigot, is arranged above the packaging machine in particular.
  • the supply of packaging machines and other comparable consumption devices for wound, web-shaped material is a particular problem of packaging technology. Due to the highly developed performance of the packaging machines, the consumption of packaging material is considerable.
  • the wound bobbins made of tin foil, paper and plastic film have a considerable weight due to the dimensions. This makes manual handling more difficult. The development is therefore towards maintaining a sufficient supply of packaging material in the field of packaging machines and also ensure the handling of the bobbins with the least manual effort.
  • a known device In a known device (EP-A-296 356) two working pins are arranged on a common, pivotable support arm. One of the working pins is in the working position when the material web is running, while the other can be supplied with a new bobbin in a loading station. The support arm can be swiveled through 180 ° in order to move the work pin between the working position and the loading position.
  • the bobbins are removed one after the other from an upper bobbin store and fed to the working spigot by a conveyor spigot. The transfer takes place with the axial alignment of the working pin and conveyor pin.
  • This known device does not yet lead to maximum performance in supplying the processing stations of a packaging machine with wrapped packaging material.
  • the invention is therefore based on the object of proposing a device for supplying packaging machines with web-shaped, wrapped packaging material, with which the packaging material can be fed with high output and without manual use of the point of consumption, in particular the working pin.
  • the bobbins can be conveyed from the upper store to a consumption station arranged in the lower region of the packaging machine.This conveying can take place particularly quickly since the intermediate conveyor can remove bobbins from the store while the vertical conveyor is still in the conveying movement .
  • the invention is particularly advantageous when processing different bobbins, namely with different packaging material, such as tin foil bobbins, paper bobbins and bobbins with plastic films.
  • Several, in particular two bobbin stores are arranged next to one another in the area of an upper level.
  • a vertical conveyor common to all bobbins or bobbin stores transports the bobbins called up to one of several consumption stations. These each consist of working pins to hold one bobbin each.
  • the work stations are arranged one below the other so that they can be reached directly from the vertical conveyor.
  • the bobbins are fed to the vertical conveyor by a conveyor pin, which takes the retrieved bobbin from the appropriate bobbin storage and feeds it to the vertical conveyor with axial displacement.
  • the conveyor pin can also be moved in the transverse direction, specifically by means of a support arm which is pivotably mounted between the bobbin stores.
  • the bobbins are fed by an overhead conveyor. This runs at a distance above the packaging machines along a mounting rail through the building with the packaging machines.
  • a bobbin conveyor is assigned to each bobbin store to take the bobbins from the overhead conveyor and to transport them until they are stored in the bobbin store.
  • the bobbin rest or a bobbin sleeve can be pulled off the working spigot by hand.
  • the bobbin sleeve can also be pushed off the working pin automatically.
  • a lateral limitation of the bobbin, namely a bobbin disk is axially displaceable with the entrainment and stripping of the bobbin core from the working pin.
  • the present embodiment relates to the manufacture of cigarette packs, e.g. of soft packs or hinge-lid packs.
  • a packaging machine 10 of a suitable, known type is used for this. Due to the design of the packaging to be produced, two different packaging materials are processed, which are available as a continuous material web and are separated from the blanks for the production of the packaging.
  • an upper material web can consist of tinfoil (tinfoil web 11), while a lower material web can consist of paper (paper web 12).
  • the packaging material is delivered in a wound form as a bobbin and made available. The material webs are pulled off the bobbins. According to the present example, tin foil bobbins 13 and paper bobbins 14 are therefore available for processing.
  • the reels 13 and 14 are conveyed from a central loading station to the individual consumption locations (packaging machines 10) by an overhead conveyor 15.
  • the overhead conveyor 15 consists of a in the packaging system encircling support rail 16, which is attached, for example, to a building ceiling or to a higher support frame.
  • Roller carriages 17 are movably supported on the mounting rail 16. These are driven by a motor 18 and moved along the mounting rail 16.
  • a bobbin 13, 14 is located on the bars 21.
  • the overhead conveyor 15 and especially the roller carriage 17 and / or the bobbin support 19 are designed in the manner described and shown in EP-A-347 586.
  • the bobbins 12, 13 are transferred to a transfer station 22 in the area of a packaging machine 10.
  • two bobbin stores 23, 24 are set up on the upper side of the packaging machine 10.
  • One bobbin store 23 - in the present case at the edge of the packaging machine 10 - serves to hold a supply of paper bobbins 14.
  • the adjacent bobbin store 24 is assigned to a store of tinfoil bobbins 13.
  • the bobbin stores 23, 24 essentially consist of two supporting rods 25, 26. These are driven in rotation and slightly diverging in the conveying direction of the bobbins. Essentially, the bobbin stores 23, 24 are designed in accordance with EP-A-296 356, but with the proviso that the two support rods 25, 26 are offset with respect to one another in height.
  • the bobbins 13, 14 rest with the circumferential surface on the support rods 25, 26. The ends of which are rotatably supported in an upright machine cheek 27.
  • a separate bobbin lift 28, 29 is assigned to each bobbin store 23, 24. This consists of two upright guide rods 30, 31 on which a bobbin holder 32 with a slide 33 and transversely projecting support pins 34, 35 is movably mounted.
  • the bobbin receptacle 32 of the bobbin lift 28, 29 designed in this way corresponds, on the one hand, to the bobbin support 19 and, on the other hand, to the associated bobbin holder 23, 24.
  • the support pins 34, 35 each serve to support a bobbin 13, 14 on its peripheral surface.
  • the support pins 34 can be moved past the bars 21 of the bobbin support 19 in the upward direction, so that the bobbin 13, 14 can be lifted off the bars 21 and taken over.
  • the empty bobbin carrier 19 can now be moved on.
  • the bobbin receptacle 32 is moved downwards with the bobbin 13, 14 into the region of the bobbin store 23 or 24.
  • the support pins 34, 35 are moved downwards so far that the bobbin 13, 14 in question is removed from the support rods 25, 26 can be included.
  • the bobbin is then moved in the axial direction in the region of the bobbin store 23, 24 (from left to right in FIG. 3). As a result, the bobbin holder 32 is released again and can be moved upwards to accommodate a subsequent bobbin.
  • the support pins 34, 35 of the bobbin receptacle 32 are at a significantly smaller distance from one another than the support rods 25, 26 of the bobbin store 23, 24, so that the relative movement described for transferring the bobbins 13, 14 can take place.
  • the bobbin stores 23, 24 are arranged transversely on the top of the machine frame of the packaging machine 10, specifically projecting beyond the machine frame (FIG. 3). As a result, a removal side of the bobbin stores 23, 24 is essentially above processing units for the bobbins 13, 14.
  • the processing units each consist of two freely projecting working pins 36, 37 and 38, 39.
  • Two working pins 36, 37 are arranged at the ends of a swivel arm 40, 41. This serves as a funding body and carrier for the working pin 36, 37; 38, 39 to move them from a receiving position (on the left in FIGS. 1 and 2) into a working position (on the right in FIGS. 1 and 2). In the working position, the material web, namely tinfoil web 11 and paper web 12, is pulled off the respective bobbin 13, 14.
  • One swivel arm 40, 41 with working pin 36, 37 or 38, 39 and further units are referred to as bobbin units 42, 43.
  • a track connector 44, 45 is assigned to each bobbin unit 42, 43. These are automatic or semi-automatic devices for connecting the running material web to the start of the new material web.
  • the track connectors 44, 45 can be configured as in EP-A-179 243.
  • the swivel arms 40, 41 are rotatable about a central bearing 46, 47. With the swivel arms 40, 41 and the working pins 36..39 attached to them, deflection rollers 48 can be moved, which are attached to the ends of holding arms 49 directed transversely to the swivel arms 40, 41. The deflection rollers 48 serve to guide the material webs.
  • the bobbin units 42, 43 are arranged one above the other in the present case.
  • a common bobbin conveyor 50 serves to supply the bobbin units 42, 43 with bobbins 13, 14, which picks up the bobbins 13, 14 in an upper position and feeds them to one or the other bobbin unit 42, 43 by downward movement.
  • the bobbin conveyor 50 is intended for the (downward) transport of bobbins 13, 14 of both bobbin stores 23, 24.
  • the bobbin conveyor 50 is arranged in the center in the area or below the bobbin store 23, but offset in the axial direction (FIG. 3).
  • the bobbins 13, 14 are removed from the two bobbin stores 23, 24 by a transfer conveyor and fed to the bobbin conveyor 50. It is a conveyor pin 51 which - like the working pin 36..39 - enters a central opening 52 of the bobbins 13, 14.
  • the conveyor pin 51 is movable axially and transversely. By inserting into the central opening 52 of a bobbin 13, 14 located in the front of the bobbin store 23 or 24, the bobbin 13, 14 is received.
  • the conveyor pin 51 is raised with the bobbin 13, 14 so that it comes out of the bobbin store 23, 24.
  • the axial movement now takes place down to the level of the bobbin conveyor 50 or a carrying device 53 thereof.
  • the bobbin is taken from the bobbin storage 23 immediately adjacent to the bobbin conveyor 50, no cross-conveying is required. Rather, the bobbin can be placed directly on the carrying device 53 after carrying out the described conveying movement. If, on the other hand, a tinfoil bobbin 13 is to be removed from the bobbin store 24, the bobbin is moved transversely and axially after the upward movement and axial displacement up to the carrying device 53.
  • the conveyor pin 51 is attached to a transport arm 54 in the present example. This is mounted as a one-armed lever in the middle between the bobbin stores 23, 24.
  • the transport arm 54 with the conveyor pin 51 at the free end can be pivoted through 180 ° to receive a tin foil bobbin from the bobbin store 24 and to transfer it to the carrying device 53.
  • the transport arm 54 is rotatably (pivotally) and axially displaceably mounted in a bearing 55.
  • the axial movement of the transport arm 54 or a shaft 56 of the same is carried out by a suitable linear drive, e.g. by a rotatable spindle 57, which is mounted here below the shaft 56 and to which the transport arm 54 is connected via a spindle nut 58.
  • the upright bobbin conveyor 50 consists of a fixed, square column 59.
  • the carrying device 53 can be moved up and down on this by means of a guide 60.
  • Two support arms 61, 62 which are spaced apart from one another are arranged on the guide. These protrude from the guide 60 on one side, specifically on the side facing the bobbin stores 23, 24.
  • One bobbin 13, 14 can be placed with the peripheral surface on the support arms 61, 62 by the conveyor pin 51.
  • the column 59 ends below the range of movement of the conveyor pin 51 (horizontal position of the transport arm 54). By further axial displacement of the conveyor pin 51, this is removed from the center opening 52 of the bobbin.
  • the bobbin placed on the supporting arms 61, 62 is conveyed downwards by the carrying device 53, alternatively to the upper or lower bobbin unit 42, 43.
  • the transfer to one of the working pins 36..39 takes place directly by moving the relevant bobbin in the axial direction the working spigot 36..39.
  • the arrangement is therefore such that the working pins 36..39 in the receiving position (on the left in FIGS. 1 and 2) are exactly centered on the carrying device 53 and thus on the center opening 52 of the bobbin.
  • the working pins 36..39 are in the receiving position immediately adjacent to the carrying device 53 and thus to the supplied bobbin 13, 14. A slight axial displacement is necessary for the transfer (FIG. 4).
  • a bobbin 13, 14 is transferred from the carrying device 53 to a working pin 36..39 by a slide member.
  • a slide 63 is attached to the carrying device 53, specifically aligned with the position of the bobbin 13, 14.
  • the slide 63 contains a relatively large-area slide plate 64 which is moved against the free side of the bobbin 13, 14. This is thereby removed from the support arms 61, 62 and pushed onto the working pins 36..39.
  • the slide plate 64 is shaped in a special way (in particular FIG. 2).
  • the slide plate 64 comes into contact with the bobbin 13, 14 above all in the lower region thereof, so that tilting or tilting of the same when being pushed off is avoided.
  • the slide plate 64 has a recess 65, through which the slide plate 64 can be extended to a little above the central plane of the bobbin 13, 14.
  • the recess 65 permits the entry of the conveyor pin 51 when a bobbin is fed.
  • the slide 63 is actuated by two cylinders 66, 67 arranged at a distance from one another. These are attached to opposite sides of the guide 60.
  • the two cylinders 66, 67 are each connected to the slide plate 64 via a piston rod 68.
  • the bobbin 13, 14 or the bobbin sleeve 69 sits on a central pin 70 of the working pin 36..39.
  • the central pin 70 is mounted so that it cannot rotate in the axial direction.
  • the central pin 70 is rotatably mounted in a hollow pin 71.
  • the hollow pin 71 in turn is connected to a machine part or to the swivel arm 40, 41.
  • a disk 74 is the stripping element.
  • This correspondingly dimensioned disk 74 also serves as a system for the bobbin 13/14 during the removal of the material web.
  • the disk 74 can be displaced in the axial direction on the central pin 70, specifically from the starting position according to FIG. 6 to the free end of the central pin 70.
  • FIG. 7 shows a stripping position.
  • an actuating element for axial displacement is attached to the disk 74. It is an actuating cylinder 75 which surrounds the central pin 70. The free end of the actuating cylinder 75 is provided with a cross-sectional widening or an inward bend 76. This acts as an annular piston in a cylinder chamber 77 of the central pin 70.
  • the cylinder chamber 77 extends in the region of the collar 73 within the cross section of the central pin 70.
  • the cylinder chamber 77 is preferably annular in cross section, that is to say cylindrical.
  • the actuating cylinder 75 emerges from the cylinder chamber 77 as a thrust member.
  • the cylinder chamber 74 can be supplied with a pressure medium, in particular compressed air.
  • a main line 78 leads into an annular collecting chamber 79 in the hollow pin 71.
  • a plurality of channels 80 arranged along the circumference enter the cylinder chamber 77 from the collecting chamber 79.
  • the cylinder chamber 77 is supplied with compressed air via these channels 80 in such a way that the actuating cylinder 75 is moved in the axial direction by pressurizing the bend 76 from the initial position according to FIG. 6 to the free end of the central pin 70.
  • the bobbin case 69 is pushed off the central pin 70.
  • the cylinder chamber 77 is vented so that it can be moved by hand or when a new bobbin 13, 14 is pushed on automatically.

  • the clamping jaws 81 are also actuated by pressure medium, in particular with compressed air. Compressed air is conveyed into a ring line 83 at the end of the central pin 70 via a central line 82 in the swivel arm 40, 41. Pressure lines 84, 85 and 86 lead from the ring line 83 to pressure chambers 87, in which the clamping jaws 81 are mounted. To actuate the same, the pressure chambers 87 are pressurized with compressed air. As a result, the clamping jaws 81 are moved radially outward against the inside of the bobbin sleeve 89. The pressure chambers 87 are vented to strip them off and push on a new bobbin. so that the jaws 81 can be moved inwards.
  • pressure medium in particular with compressed air. Compressed air is conveyed into a ring line 83 at the end of the central pin 70 via a central line 82 in the swivel arm 40, 41.
