Definitions

  • the invention relates to a calender with a Stand that is inclined in the longitudinal direction to the horizontal runs, and a roll stack, the rolls on Stands are held, as well as a transport device for installing and removing the rollers.
  • Such a calender is known from US 3 154 008.
  • the stack of rollers is on the top of the sloping stand.
  • the roller When changing the roller, the roller must hung on a crane, approximately vertically from the stacking level pulled out and then shifted horizontally until they are on a vacant space next to the calender can be lowered. Because of the risk of commuting the roller must be very careful when transporting the roller and therefore take place slowly.
  • This type of placement of the roll stack on the inclined stand is in the have been retained recently, such as the unpublished DE 198 32 066 shows.
  • the invention has for its object a calender of the type described in the introduction, in which the roll change is simplified.
  • This object is achieved in that the stack of rollers on the underside of the inclined stand is arranged and that the transport device a roller trolley that is horizontal in the longitudinal direction is movable under the roll stack, and a roll lifting device, which each have a roller when installed from Brings the roller cart into the associated stacking position and when removing from the associated stacking position puts down the roller cart.
  • rollers are used to change the rollers, after being moved out of the stack are, by means of the roller lifting device on the roller trolley lowered.
  • the horizontal transport takes place then by moving the roller cart on the floor, whereby there is no fear of the roller swinging.
  • the same advantages also apply when installing a Roller.
  • roller carrier on rails is movable. This facilitates horizontal transport.
  • the roller lift device has a crane. Because the crane ropes essentially take over only a vertical transport exists no risk of commuting.
  • the position of the rollers on the stand is expedient fixable with locking devices. This ensures that the transport of the roller to be changed is not disturbed by the other rollers.
  • the fixation can be on the stand or on other parts fixed roller.
  • Another preferred option is that the locking devices by hydraulic clamping devices) are formed.
  • the hydraulic tensioners are easy to operate and need no difficult manual operations like loosening the bearing screw.
  • the invention is based on one in the Drawing schematically illustrated embodiment of a calender according to the invention explained in more detail.
  • the calender shown has a stand 1, which is at an angle of about 45 ° to the horizontal extends and below on a fixed base 2 rests.
  • the upper end is over side members 3 with supports 4 connected.
  • a roll lifting device 13 is designed as a crane with crane cables 14 and horizontally movable on the side members 3.
  • a roller carrier 15 is laid on the ground Rails 16 horizontally movable in the longitudinal direction, such as this is indicated by the double arrow 17.
  • a lifting table 18 can be moved on the same rails 16, which has a height-adjustable work platform 19 wearing.
  • the lower roller 6 is by a hydraulic tensioning device 20 fixable on stand 1.
  • the top roller 7 is by a hydraulic clamping device 21 on the stand 1 fixable.
  • the center rollers 8 are dashed like this is indicated, carried by levers 22 which around Pivots 23 are pivotable in the stand and with one Stop 24 can cooperate with their location fixed a lowering of the rollers.
  • the roller carrier 15 is in a position in which the lower roller 6 is removed can.
  • the roller is lifted off the crane hook the roller lift device 13 detected and in the Lower position A1 shown in dashed lines lowered.
  • the roller carrier 15 becomes together with the roller brought into position A2, where the removal to a Service point can take place.
  • the roller trolley 15 also has a rest position A3, in which he has a allows free movement of the work platform 19.
  • the steps are to install a new roller perform in reverse order. Should one of the rollers located above the lower roller 6 the roller nips in the usual way open.
  • the crane hooks of the roller lift device 13 grasp the roller to be changed, lower it slightly depending on what these are on the circumference of the ones below Roll rolls until it is freely lowered can be.
  • a guide roller 11 has to be removed, this can be done with the help of the lifting table 18.
  • This is usually in a parking position B1, but can be done by horizontal and vertical Raise the work platform 19 to the working position B2 brought where it can accommodate the guide roller.
  • the guide roller 11, shown as 11 ' in one be carried by the support 4 frame 25.
  • Another working platform can be located above the roll stack 5 located along an oblique guide is movable.
  • the frame 25 can also be used as a reserve roller frame be used.
