Definitions

  • the invention relates to a method for changing bobbins according to the preamble of claim 1 and a device for feeding material webs according to the preamble of claim 3.
  • the object of the present invention is to improve the method mentioned at the outset and a corresponding device in such a way that a connection of the front end of a connecting track to the outlet end of a running track is ensured without overlap, without the working speed of the packaging machine being reduced.
  • the device shown is part of a packaging machine, in particular for the production of hinged boxes, or is assigned to the latter.
  • the packaging machine or a punching unit for the production of (collar) blanks is continuously supplied with a material web of thin cardboard or the like as a runway 10 at high conveying speed.
  • This runway 10 is drawn off from a first reel 11, which in the present case is almost used up.
  • a new bobbin 12 or its connecting web 13 is introduced into the conveying flow and fed to the packaging machine.
  • a bobbin exchange can then take place in the area of the first bobbin 11, essentially only a cylindrical (cardboard) core 14 having to be pulled off a pivot pin 15 of a support device for the bobbins 11 and 12, which is not shown in detail.
  • the "active" run-off track 10 is conveyed by pull rollers, namely pulled off the bobbin 11.
  • a pair of main pulling rollers 16, 17 is arranged towards the packaging machine and is arranged at the outlet end of a conveyor track 18 for the material webs, which in the present case rises obliquely.
  • two pairs of pulling and pushing rollers 19 and 20, each for one of the material tracks 10, 13, are arranged.
  • these pairs of pulling rollers each consist of a fixed pulling and pushing roller 19 or 20 in close proximity to one another and a movable, smaller counter-roller 21 which alternatively is delivered to one or the other pulling and pushing roller 19, 20 and on its circumference or on one of the material webs 10, 13 is pressed.
  • the train and push rollers 19, 20 with counter roller 21 are arranged on the introduction side of the conveyor track 18, the counter roller 21 always being movable between the material tracks 10, 13.
  • the two pulling and pushing rollers 19, 20 are each assigned a deflection roller 22 and 23 for the material web 10, 13 in front in the conveying direction. These deflecting rollers 22, 23 ensure that the material webs 10, 13 are each at a certain angle to the train. and push rollers 19, 20 are guided.
  • the conveyor track 18 is defined in a region facing the main drawing rollers 16, 17 by fixed lateral or upper and lower guide walls 24, 25. These are arranged converging in the direction of the main drawing rollers 16, 17.
  • the guide walls 24, 25 end immediately adjacent to the circumference of the main drawing rollers 16, 17, in part adapting to the arcuate course of the runway 10.
  • the conveying path 18 is delimited on the outside by outer walls 26, 27, which are also arranged to converge slightly in the conveying direction and each have suction bores 28 on the inside. These are connected to a vacuum source, not shown in detail, and are controlled so that a front end 29 of the connecting track 13 is fixed in a standby position by the suction bores 28 on the associated outer wall 26 and 27, respectively.
  • a middle piece 30 is arranged between the outer walls 26 and 27 and the two material webs 10, 13 and limits a relatively narrow guide gap for the material webs 10, 13 with respect to the outer walls 26, 27.
  • the central piece 30 On the entry side of the conveyor track 18, the central piece 30 is followed by guide walls 31 and 32 assigned to the material tracks 10, 13, which extend as far as the deflection rollers 22 and 23 and serve to guide the material tracks 10, 13 in this area.
  • the aforementioned guide walls 31, 32 are provided with recesses for the passage of the counter roller 21.
  • a cutting device 33 is arranged. This has the task of separating an end piece of the runway 10 from the latter when the bobbin 11 in question has been used up.
  • the cutting device 33 is controlled by control elements, in the present case by optical sensors 34, 35, which in each case monitor the end of the runway 10 at corresponding points, namely directly adjacent to the deflecting rollers 22, 23.
  • the end piece of the run-off track 10 separated by the cutting device 33 is accordingly relatively short.
  • the connecting path 13 to be inserted into the conveying flow in the correct position lies with its front ends 29 in the ready position during the conveyance of the runway 10 in the conveying path 18, namely at a stop 36.
  • the stop 36 becomes out of the blocking position moved out for the connecting web 13 and at the same time driven in the conveying direction by the associated pulling and pushing roller 20 in connection with the counter roller 21.
  • the movement of the individual organs is coordinated with one another in such a way that the front end 29 of the connecting track 13 follows the running end of the drain track 10 directly, namely with a very small distance. As soon as the front end 29 has reached the main drawing rollers 16, 17, the conveyance is taken over by them.
  • the pulling and pushing rollers 19, 20 and the counter roller 21 are mounted on a common, approximately T-shaped roller carrier 37, the counter roller 21 indirectly via a (two-armed) actuating lever 38.
  • This is connected to the roller carrier 37 via a rotary bearing 39.
  • an actuating element acts on the actuating lever 38, in the present case a pressure medium cylinder 40 which can be acted upon with pressure medium in both directions of movement of a piston rod 41.
  • the counter-roller 21 is fed to one or the other pulling and pushing roller 19, 20 by pivoting movements of the actuating lever 38.
  • the cutting device 33 is designed as a rotary cutter.
  • a cylindrical cutting knife 46 is rotatably mounted in a cylindrical knife housing 45.
  • a reciprocating rotary movement along a limited angle of rotation takes place via the link 43.
  • the cutting knife 46 is designed or the through slot 47 is dimensioned on the input side in such a way that a peripheral region of the cutting knife 46 serves as a stop for the front end 29 of the connecting track 13 which is in the standby position.
  • the through-slot 47 is formed in the entry area in such a way that in the end positions of the cutting knife 46 a circumferential area adjoining the cutting edge 48 or 49 acts as a stop 36.
  • the front end 29 of the connecting track 13 is practically in the cutting plane.
  • the relative position of the through slot 47 with respect to the exit recess 54 is selected so that the respective continuous runway 10 can be freely conveyed through the knife housing 45 without hindrance.
  • the main pulling rollers 16, 17 and the pulling and pushing rollers 19, 20 are in geared connection with one another.
  • the (larger) main drawing roller 17 is continuously driven by a motor, not shown in the drawings.
  • a toothed belt wheel 56 of the main pulling roller 17 is connected to a corresponding toothed belt wheel 57 of the pulling and pushing roller 20. This in turn is in drive connection with the pulling and pushing roller 19.
  • the dimensions of the toothed belt wheels 56 and 57 and the diameter of the main pulling roller 17 and the pulling and pushing roller 20 are selected so that the pulling and pushing rollers 19, 20 are driven at a slightly lower speed than the main pulling roller 17.
  • the diameter of the pulling and pushing rollers 19, 20 is 0.6 mm smaller than that of the main pulling roller 17. This ensures that the material web 10, 13 is always transported in the region of the conveyor path 18 under slight tension, in any case without creases. A slippage of the material web 10, 13 or an overvoltage is avoided in that the main pulling roller 17 or the toothed belt wheel 56 associated therewith is equipped with a freewheel 58 acting in the corresponding direction.
  • the slightly higher speed of the main traction rollers 16, 17 only comes into effect during the short moment after an end piece of the run-off track 10 has been severed, so that it is transported slightly faster than the front end 29 of the subsequent connecting track 13.
  • the main pull rollers 16 and 17 and the pull and push rollers 19 and 20 rotate continuously.
  • the conveying effect for the material web in the area of the pulling and pushing rollers 19, 20 is effected exclusively by the abutment of the counter roller 21.
