Definitions

  • the invention relates to a device for producing scale belt rolls from flat, flexible objects, which are shingled one above the other on a conveyor belt, according to the preamble of patent claim 1.
  • the object of the invention is therefore to improve a device according to the preamble of claim 1 in such a way that the replacement of the respectively wound scale tape roll with a winding core can be accomplished simply and quickly, essentially without interrupting operation.
  • the swivel arms can be moved back and forth simply and quickly in such a way that one pin is in the winding position while the other is outside the belt conveyor, so that the finished wound scale roll is removed and a new winding core is attached can.
  • the device according to the invention can therefore significantly increase the degree of utilization of the machines and thus improve their performance.
  • the exchange of the finished wound scale roll for a new winding core is very simplified in that it can be carried out in addition to the conveyor belt driving the scale roll during its winding.
  • a device for unwinding rolls of paper or other sheet-like material in which the roll is held between pivotable arms which are provided with mutually aligned, mutually facing pins which hold the roll on both sides from this intervene in their winding core.
  • the pivotable arms are neither axially displaceable on the axles supporting them, nor are they intended to accommodate two rollers.
  • a particular problem with the removal of the fully wound scale tape roll is the temporary fixing of the holding tapes until the separation of their supply rolls and the fastening of their ends to the finished wound scale tape roll itself.
  • the swivel arms are attached to a radial support which carries clamping jaws which can be lowered on the circumference of the respective scale belt roll in the region of its holding bands and can be pressed on to fix them.
  • clamping jaws are actuated when the holding tapes have been wrapped once or twice around the scale tape roll after the scale tape roll has been finished. They are released again for the purpose of replacing the scale tape roll when the retaining tapes are separated from their supply rolls and knotted with themselves on the scale tape roll or fastened in some other way.
  • the flat workpieces or sacks to be wound are fed in the form shown in FIG. 1 in a scale formation on a conveyor belt of the winding device. Since the scale spacing of the incoming workpieces may differ, a device for equalizing the scale spacing is provided so that a uniformly wound scale tape roll can be formed. This device has a pressure roller 25. On the opposite side, ie below the scale, there is a sensor 26 which scans the workpiece ends, the pulses of which are passed on to an electrical intermediate circuit 27.
  • the scale After being scanned by the sensor 26, the scale is thrown onto an endless conveyor belt 28 which is formed from individual belts and runs over the rollers 29 to 34 which are rotatably mounted in a pivotable frame 35.
  • the drive roller 36 is also attached to the frame 35, via which the strands are returned to the rollers 29.
  • the frame 35 is pivotally mounted about the axis of the rollers 31 and is supported, for example, under the supply roller 37 to be wound by pneumatic cylinders 38, which have the task of tracking the frame 35 of the supply roller 37 in order to avoid out-of-roundness of the supply roller 37 which occurs during winding can compensate.
  • a supply shaft 39 is provided on floor-mounted storage, from which retaining straps 40 are pulled, which are wound up in layers in a known manner with the workpieces on the supply roll 37.
  • the axis of the drive roller 36 is equipped with a rotary pulse generator 41, the pulses of which are input to a counter 42.
  • the counter 42 and the drive motor, not shown, of the drive roller 36 are with the Zwi circuit 27 electrically connected.
  • the counter 42 can be set to a predetermined number and is switched so that the drive motor is stopped after reaching this number.
  • the predetermined number is chosen somewhat larger than the intended scale band.
  • the sensor 42 is reset to zero when a workpiece end passes by the sensor 26. If there is no workpiece, so that the counter 42 reaches the predetermined number, the conveyor belt 28 is stopped and it only starts to run again after the next workpiece has run through. Therefore, approximately the same scale distance is achieved on the conveyor belt 28.
  • the core 45 of the supply roll 37 is held by a pin 46 which is fastened in the free end of a lever 47.
  • the other end of the lever 47 is rotatably mounted on a bush 48 together with a second lever arm 49.
  • the lever arm 49 carries a pin 50 corresponding to the pin 46 at its free end, but which extends in the opposite direction.
  • Pressure medium cylinders 51, 52 are articulated to the lever arms 47 and 49, with which they or the supply roll 37 can be lowered onto the conveyor belt 28 and raised from there.
  • the bushing 48 is smoothly and longitudinally displaceably mounted on an axis 53 which is fastened in a stand 54 arranged on both sides next to the conveyor belt 28.
  • a guide part 55 is connected to the bushing 48 by a web 56.
  • a roller 57 is loosely rotatably mounted on the guide part 55 and runs in a U-iron 58 which connects the two stands 54.
  • the free ends of the pressure medium cylinders 51, 52 are articulated on the guide part 56.
  • the bushing 48 can now be moved with the levers 47, 49, so that the pin 46 is above the conveyor belt 28 and the pin 50 is outside the winding area. While a new supply roll 37 is being wound on the pin 46, the finished supply roll can be removed from the pin 50 and a new core 45 can be prepared. After completion of the supply roll 37 on the pin 46, it is lifted off the conveyor belt 28 by means of the pressure medium cylinder 51 and the bush 48 is shifted into its other extreme position, and the supply roll 37 is lowered on the hall floor and pulled off the
  • the pressure medium cylinders 51, 52 connecting the levers 47, 49 to the sled-shaped guide part 55 are hydraulic piston-cylinder units, while the conveyor belts running over the frame-shaped frame 35 pass through a pneumatic cylinder 38 to the winding core or the forming scale roll 37 can be pressed.
  • the pneumatic cylinder 38 has a stroke of approximately 100 mm and is held in its central position by the fact that the hydraulic cylinders 51, 52 raise the levers 47, 49 in accordance with the winding progress.
  • the hydraulic cylinders 51, 52 can be actuated in that the pneumatic cylinder is provided with a limit switch.
  • the pneumatic cylinder 38 has good resilient properties, so that it is able to compensate for out-of-roundness of the scale roller 37 that is being formed.
  • the retaining straps 40 are wound around the roller 37 for about two more turns.
  • the press device 60 is then switched on and this holds the belts 40 in place when the roll is lifted off the press belts or the scale belt 33, 28.
  • the wristbands are only fixed manually when the empty roll is in the take-up station.
  • the pressing device 60 is mounted on an arm 61 which is firmly connected to the lever 47.
  • a cross member 62 is fastened to the arm 61 and a pressure cylinder 63 is articulated to the free end thereof.
  • the piston rod of the pressure cylinder 63 is articulated on a lever 64.
  • One end of the lever 64 is articulated to a bracket 65.
  • a cross member 66 is articulated in a rocker-like manner, to which pressure pieces 67 are articulated, which can press onto the holding tapes 50 wound around the supply roll 37 when the pressure cylinder 63 is actuated.
  • the bracket 65 encompasses half of the arm 61. At the same height on the arm 61 there is a second bracket 68 which is symmetrical to the bracket 65 and which is connected to the bracket 65 by screws 69 and clamped together with it on the arm 61.
  • a correspondingly designed second pressing device 60 is arranged on the arm 49. However, this is not shown in FIG. 2.
