Definitions

  • the invention relates to a rolling device for winding rolls, in particular made of paper or cardboard, according to the preamble of claim 1.
  • Devices of this type in which the winding roll is clamped axlelessly between the clamping heads during unwinding and is held by these, are used for unwinding paper or cardboard webs before subsequent processing machines, e.g. B. a cross cutting machine.
  • the clamping heads can be moved towards and away from each other in the direction of their axis of rotation for loading with a new winding roll, for unloading the rest of the roll and for adjusting to different roll widths. Depending on the diameter of a full winding roll, these are raised to the unwinding position.
  • a roll-off device in which the clamping heads for lifting the full winding rolls can be moved vertically by means of a lifting drive.
  • they are attached to support arms that are used to clamp the Winding roll are arranged displaceably on a horizontal bar, the bar being guided vertically displaceably by a lifting height by means of a lifting drive.
  • the support arms extend in and against the web running direction as cantilever arms away from the beams mounted in the side supports. Large torques therefore occur with heavy winding rolls.
  • the frame of the rolling device must therefore be made very solid to accommodate the torques, and the guidance of the vertical movement of the support arms must be designed to be complex.
  • US-A 2,346,948 describes a unwinding device according to the preamble of claim 1 with a piston-cylinder unit which presses to lift the winding rollers and is arranged laterally next to one of the supports transversely to the web running direction.
  • a brake is arranged on one side on the inner side of the bearing housing of the clamping head.
  • the invention has for its object to improve a generic unwinding device with a compact design so that it is suitable for unwinding heavy winding rolls.
  • a pulling piston-cylinder unit as a lifting drive can be implemented in a structurally simple manner and is capable of applying the necessary forces when lifting heavy winding rolls. In addition, a space-saving vertical arrangement is made possible.
  • the unwinding device can be built very compactly and is therefore particularly suitable for arranging several unrolling devices one behind the other. With such arrangements, there is limited space, which requires small dimensions of the individual unwinding devices both in the web running direction and in height and width.
  • the unwinding device according to the invention requires less space in height and web running direction than the maximum diameter of a winding roll to be unwound. Foundation pits are not required.
  • Claims 4 and 5 contain advantageous embodiments of a drive for the transverse adjustment of the stand, the drive being particularly space-saving by means of an immovable chain attached to the floor with a motor attached to the respective stand.
  • the unwinding device has two stands 1, 2 which are constructed in mirror symmetry and are arranged at a distance from one another. They are on two parallel rails 3, 4 fastened to the floor, with a T-shaped cross section towards and towards each other stored movably away from each other.
  • Each stand 1, 2 is made up of two vertical supports 5, 6 with a U-shaped cross section, which are fastened to a base plate 7 and are connected at their upper end to a crossbar 8.
  • Guides 9, 10 fastened to the underside of the base plate 7 engage around the rails 3, 4.
  • Side parts 11, 12 fastened to the outside of the supports 5, 6 each support them on the base plate 7 transversely to the web running direction.
  • An electric or hydraulic motor 13 which is attached to the base plate 7, serves as the drive for the transverse adjustment of the stands 1, 2.
  • the motor 13 drives a pinion 14 which is partially wrapped in an immovable chain 15 which extends between the rails 3, 4 in the direction of web travel and is fastened to the floor at both ends.
  • the two supports 5, 6 open on the sides facing each other form a vertical guide for a bearing housing 16 arranged between them.
  • the bearing housing 16 has lateral rollers 17 with axes running in the direction of web travel, which are in the U-profile of the supports 5, 6 according to Art a backdrop guide are fitted.
  • the guide function of the preferred rollers 17 can also take over lateral sliding blocks.
  • a horizontal clamping head 18 is rotatably mounted centrally on the inside of each bearing housing 16 and is connected to a shaft 19 which extends outwards through the bearing housing 16. At least on one, preferably on both stands 1, 2, the shaft 19 is connected to a brake 20 which is fastened to the outside of the bearing housing 16.
  • the bearing housing 16 with clamping head 18 and brake 20 in the lower unloading position for a roller rest is shown in dashed lines.
  • the bearing housing 16 with the clamping head 18 and the brake 20 can be lifted from the lower roll receiving and unloading position to the upper unwinding position by means of a lifting drive which acts symmetrically on the vertical plane 29 through the axis of rotation 22 of the clamping heads 18 on the bearing housing 16.
  • the linear actuator is shown in more detail in FIG. 2:
  • the cylinder 23 of a hydraulic piston-cylinder unit is fastened vertically to a side part 12.
  • the length of the cylinder 23 is approximately half the height of the support 6, so that the piston rod 24 extends in the extended position into the area of the crossbar 8.
  • a free-running gear 25 is fastened, which is suspended in a pull chain 26 guided in the crossbar 8.
  • the pull chain 26 is attached at one end to the crossbar 8, with the other end to the bearing housing 16 perpendicularly above the axis of rotation 22. It is guided by two guide wheels 27, 28 fastened to the crossbar 8, the gear wheel 25 fastened to the piston rod 24 being located between the start of the chain and the first guide wheel 27, and the second guide wheel 27 deflecting the chain 26 vertically downward.
  • This arrangement in the manner of an inverted block and tackle, causes a 2/1 ratio of the movement of the piston rod 24 to the bearing housing 16. This enables the movement of the bearing housing 16 from the floor to the unwinding position below the crossmember 8 with the space-saving arrangement of the piston-cylinder Unit 23, 24 vertically next to the support 6, in which the piston rod 24 can only carry out half the required stroke of the bearing housing 16.
  • the unwinding device is thus capable of lifting a full winding roll 21 transported by an industrial conveyor itself into the unwinding position. Separate lifting devices such as lifting tables, cranes etc. are not required.
  • the dimensions of the unwinding device both in the web running direction and in height are small; no foundation pits are required. The small dimensions make it possible to arrange several unrolling devices one behind the other in order to lay several webs one above the other in the subsequent processing machine, e.g. B. a cross cutting machine. Then there is limited space, since the individual unrolling devices are integrated in a frame, the stands of which are arranged between the unrolling devices. Above the unrolling devices are longitudinal members of the scaffold, in which guide rollers and, if necessary, splice devices for a roll change are fastened.
  • the full winding rolls 21 are preferably fed to the unwinding devices by a floor conveyor running centrally in the web running direction, in particular a chain conveyor, in the web running direction; lateral feed across the web direction is also possible.
  • the stands 1, 2 are so far apart that a winding roller 21 can be moved between the clamping heads 18.
  • the clamping heads 18 move from both sides into the sleeve of the winding roller 21, then the piston-cylinder unit 23, 24 lifts the bearing housing 16 with the suspended winding roller 21 into the upper unwinding position. After unwinding, the remainder of the roll is lowered accordingly and transferred to the floor conveyor by moving the stands 1, 2 apart.
