Definitions

  • the invention relates to a device for unwinding a web of material from a roll with two support arms which are mounted so that they can be swiveled up at a distance from one another transversely to the web and which have means for receiving and rotatably holding the roll.
  • Devices of this type are used in particular for unrolling paper webs in the paper processing industry.
  • the paper roll to be unwound is suspended between the support arms and raised for unwinding.
  • two clamping heads rotatably fastened to the support arms are inserted into the two lateral openings of the winding tube.
  • Such unwinding devices are described for example in DE-GM 85 11 986 and in DE-OS 29 51 336.
  • a new roll for changing rolls is fed on underfloor conveyors which convey the roll into the receiving area of the clamping heads, which can be moved apart and down to receive a roll. If there are several unwinds arranged one behind the other in the web running direction, it is advantageous for a quick roll change to feed the new rolls from the side, transversely to the web running direction. In devices with support arms attached in side stands, space must be left between the unwinding stations because the stands stand in the way of a side loading, and an additional conveying in the direction of web travel is required, which brings the roll into the receiving position of the clamping heads.
  • the supporting beams suspended in a frame in the generic device according to DE-GM 85 11 986 can be swiveled up on the loading side for insertion of a new roll.
  • the support beams swivel into a vertical position to accommodate a new roll, then the roll is raised by shortening the support arms.
  • a disadvantage of this device is that all forces are transmitted by horizontal supports of the frame, which must therefore be made very difficult for reasons of stability.
  • the invention has for its object to provide a generic device that is structurally simple and space-saving.
  • the lifting of the roll into the unwinding position can be accomplished by a pivoting movement, so that an expensive vertical guide is unnecessary.
  • the roll receiving devices can be moved at the ends of the support arms in a horizontal direction, so that the new roll does not have to be positioned transversely to its axis when changing rolls.
  • the support arms can be set approximately vertically in the unwinding position and the torques acting on the swivel axes can be significantly reduced. In the event of a subsequent axial correction of the unwinding position, the elements which prevent the support arms from pivoting are thus subjected to considerably less stress.
  • the device according to the invention described in Figures 1 and 2 is supported on two horizontal base plates 1, 2, which are arranged at a distance greater than the maximum roll width from each other, horizontally movable transversely to the axis of the roll 3 to be unwound, in Figure 2 from left to right and vice versa.
  • the shaft 8 has free-running rollers 10, 11 at both ends, with which it can be moved back and forth on the base plates 1, 2.
  • the bearings 12 of the shaft 8 in the rollers 10, 11 are also the pivot bearings for the pivoting movement of the support arms 4, 5.
  • the drive for this movement is located on one side (on the right in FIG. 1) on the base plate 2.
  • a piston-cylinder unit 13 which is fastened on the one hand to the base plate 2 and on the other hand to a mobile carriage.
  • the carriage is constructed from two parallel side parts 14, 15, through which the shaft 8 is guided at one end parallel to the axis of the roller 3 and freely rotatable, so that the carriage is supported on the shaft 8.
  • the other end of the carriage is supported on a roller 16 which sits on a shaft 17 between the two side parts 14, 15 and runs between a guide rail 18 and the base plate 2.
  • an electric motor with a chain can also be used as the drive.
  • a synchronizing device contains a synchronizing device.
  • This consists of a synchronous shaft 19 extending across the working width, which is rotatably mounted on the drive side in the side part 14 and on the other side in a connecting plate 20 suspended at the end of the shaft 8.
  • Pinions 21, 22 are fastened on both ends of the synchronous shaft 19 and each run in a toothed rack 23, 24 connected to the respective base plate 1, 2.
  • a wheel 25 is fastened, which runs in a guide rail 26 with a U-shaped cross section in order to ensure the engagement of the pinion 21 in the rack 23 at all times.
  • drive sticks or chains can also be used.
  • a pivot lever 27 is fastened on the shaft 8 in the area between the two side parts 14, 15 and secured against rotation with a feather key 28.
  • a spindle nut 29 is rotatably mounted in a fork about an axis parallel to the shaft 8.
  • a threaded spindle 30 is guided through the spindle nut 29 and is driven by a geared motor 31 which is rotatably fastened to the side parts 14, 15 above the roller 16.
  • the lever 27 With the geared motor 31, the lever 27 can thus be pivoted, as a result of which the shaft 8 is rotated and the support arms 4, 5 fastened on it are also pivoted.
  • a gear motor 31 instead of the spindle mechanism 29, 30 with a gear motor 31, it is also possible to use a hydraulic piston-cylinder unit.
  • the distance between the clamping heads 6, 7 from one another can be adjusted to accommodate a new roll 3 and to adapt to different roll widths.
  • a spindle nut 32, 33 is fastened in each support arm 4, 5, through which a threaded spindle 34, 35 leads parallel to the shaft 8 to the outside.
  • the threaded spindle 34 of the support arm 4 is mounted on the outside in a lever 36 fastened on the shaft 8, to which a geared motor 37 is fastened as a drive.
  • the threaded spindle 35 of the support arm 5 is mounted on the outside in the pivot lever 27 and is driven by a geared motor 38 fastened thereon.
  • Fig. 3 shows the unwinding device in the unwinding position.
  • the paper roll 3 is clamped on its winding sleeve between the clamping heads 6, 7 and is held freely in the raised position by the support arms 4, 5.
  • the axis of rotation of the roller 3 is not exactly vertically above the shaft 8, but in a horizontal position b, which is offset somewhat in the direction of the swivel drive 31.
  • the shaft 8 is at a minimal distance from an underfloor conveyor 39 which extends transversely to the web.
  • the paper web 40 is drawn off from the roll 3 approximately horizontally in the direction of the arrow shown.
  • FIGS. 4-6 The loading with a new roll 3 is shown in Figures 4-6.
  • the device moves away from the underfloor conveyor 39 - to the right in FIGS. 4-6 and thus creates space for the feed of a new full roll 3 by the conveyor 39.
  • the axis of rotation of the clamping heads 6, 7 is located now in position c.
  • the new roller 3 is fed in the axial direction from the side opposite the lifting drive 29 - 31.
  • the threaded spindle 30 does not interfere, since it is arranged outside the working width on the drive side (FIG. 4).
  • the clamping heads 6, 7 are moved apart a distance larger than the roll width and the empty winding tube is removed. This can be done while the new roll 3 is being fed into the take-up position. Since the device is freely accessible on the side opposite the roll feed (right in FIG. 4), the empty winding tube can be removed on this side.
  • the underfloor conveyor 39 guides the roller only in one direction transverse to the web 40 into the receiving position. It is not necessary to transport the roll transversely to this direction.
  • clamping heads 6, 7 After the clamping heads 6, 7 have reached their position coaxially to the roll axis, they are moved into the winding tube by moving the support arms 4, 5 together and thus clamp the roll 3. Subsequently, the clamped roller 3 is raised into the vertical unwinding position by pivoting the support arms 4, 5 and brought into the horizontal unwinding position b by moving the device in the horizontal direction. The unwinding device with the roller clamped is then again in the position shown in FIG. 3.
  • FIGS. 7 and 8 show the principle of another embodiment of the invention, in which the horizontal movement of the pivot bearings 41 is not effected by moving the entire rolling device, but with a double-link suspension of the support arms.
  • the device shown there has fixed stands 42 on both sides transverse to the paper web, on each of which a lever 43 is articulated. At the ends of the levers 43 which are not articulated on the stand 42, a support arm 44 is fastened so as to be pivotable upward via a shaft. By means of drives, not shown, the levers 43 on the stands 42 can be pivoted independently of one another about the articulation axis 45 and the support arms 44 on the levers 43 in the pivot bearing 41.
  • the horizontal movement of the pivot bearings 41 in the direction of the underfloor conveyor 39 for positioning the clamping heads in the horizontal receiving position a is effected by pivoting the levers 43 (FIG. 8).
  • the vertical positioning of the clamping heads along the line a takes place through the vertical components of the two pivoting movements.
  • the lifting of the roll 3 and its movement into the horizontal unwinding position b -Figur7- is also carried out by the combination of the pivoting movement of the support arms 44 and the pivoting movement of the lever 43.
  • the pivot bearings 41 of the support arms 45 do not move exactly horizontally, but on an arc with a horizontal component.
