Definitions

  • the invention relates to a loading device for a film roll rotary bearing with two rotary bearings, one of which is arranged above the other.
  • the invention is based on the object of providing a loading device for film roll rotary bearings with two rotary bearings, one of which is arranged above the other, by means of which the loading of both bearings is simplified.
  • both pivot bearings should be able to be loaded with the same device.
  • the device should also be able to be operated by inexperienced forces. In particular, damage to the pivot bearings should be avoided by inserting the heavy rollers.
  • a pair of loading arms is pivotally mounted on the lower roller pivot bearing, the length of which is at least equal to the distance between the two roller pivot bearings, the free end of each loading arm carries a pawl and one or two hydraulically pivotable intermediate levers are provided are whose free ends are articulated and slidably connected to the loading arm (s).
  • This loading device makes it possible to insert film rolls with the same device belonging to the roll bearing into the two rotary bearings. The film roll will lock when open pawls rolled onto the ends of the two loading arms and then held at the loading arm ends by closing the pawls.
  • the loading arms are raised horizontally or with the ends holding the roller slightly above the lower pivot bearing, so that there is a slight slope to it.
  • the film roll can be rolled over the loading arms into the lower roll pivot bearing.
  • the loading arms are hydraulically swiveled up using the intermediate lever until the shaft of the film roll is above the upper film roll bearing.
  • the two shaft ends of the film roll are expediently on an inclined plane on which the shaft with the film roll can roll into the upper roller bearing.
  • the pawls are then opened so that the roller rolls into the pivot bearing. Conversely, the empty rollers can be removed from the pivot bearing.
  • the intermediate lever or levers can be pivoted by a pivotably mounted hydraulic piston / cylinder unit.
  • the intermediate lever (s) are preferably designed with one arm and engage the piston rod of the piston / cylinder unit in the central region of the intermediate lever (s).
  • the end of the intermediate lever facing away from the loading arms is pivotably attached to the machine frame.
  • the cylinder of the piston / cylinder unit is also pivotally attached to the machine frame, so that the unit can also pivot when the loading arms are pivoted upwards.
  • the free ends of the intermediate levers are expediently guided in elongated holes which are formed in the loading arms. This ensures that the point of engagement of the intermediate lever on the loading arms can move during the pivoting movement of the loading arms.
  • the pawls at the ends of the loading arms can expediently be actuated by hydraulic piston / cylinder units.
  • the operator can therefore release the pawls by hydraulic control means when the loading arms are pivoted into the roll-in position to the lower or upper roller pivot bearing.
  • the upper roller pivot bearing is generally laterally offset from the lower roller pivot bearing.
  • the figure shows a two-story roller bearing with hydraulic insertion device for both bearings.
  • the lower film roller bearing is designated by the reference number 2 and the upper film roller bearing by the reference number 3. Both bearings are firmly attached to the machine frame.
  • Two parallel loading arms 4 are pivotable about the lower film roller bearing 2, of which only the front arm is visible in the figure and the length of which is somewhat greater than the distance between the bearings 2 and 3.
  • a pawl 5 is pivotally attached, which can be opened and closed by a hydraulic piston / cylinder unit 10.
  • the pivoting of the loading arms 4 is effected hydraulically by a correspondingly dimensioned hydraulic piston / cylinder unit 8, which is pivoted at 11 on the machine frame depends.
  • the piston rod 8a of the unit 8 engages in the central region of an intermediate lever 6 and, when the piston rod 8a is pulled in, causes this one-armed lever 6 to pivot about its articulation point 12 on the machine frame.
  • the pivotable end 7 of the intermediate lever 6, which, like the loading arm 4, is provided in pairs, engages with pins in an elongated hole 9 formed in the loading arm 4.
  • the film roll 1 (weight, for example 1200 kg) is rolled onto the ends of the loading arms 4, for example by hand, with the pawls open. After closing the pawls, the loading arms 4 are then lifted into the horizontal by retracting the piston rod 8a of the piston / cylinder unit 8, so that the roller 1 can be rolled into the lower roller pivot bearing 2 by hand. (Film roll 1a). To insert the film roll 1b into the roll bearing 3, the loading arms 4 are pivoted down again into the position shown in the figure. The film roll is rolled up on the ends of the loading arms 4 with the pawls 5 open.
  • the pawls 5 are closed as shown, and the loading arms 4 are pivoted up with the thus secured film roll by pulling in the piston rod 8a of the hydraulic unit 8 until the shaft of the film roll 1b is on the inclined surface 3a of the roller bearing 3.
  • the pawls 5 are opened hydraulically, so that the roll of the drawer poor 4 is released and can roll over the surfaces 3a in the upper roller bearing 3.
  • the device according to the invention makes it possible to load both roller bearings 2 and 3 without an external lifting device.
  • the device according to the invention is suitable for manufacturing processes in which foils made of plastic, paper, light metal and the like are unrolled as a web from rolls and continuously processed, e.g. in the lamination of web material, wallpaper production, plastic or paper bag production and similar processes.
