Description

  • The invention relates to a cutting device of on a roll winded web, as a paper web, which device has a frame on which the roll can be placed horizontally, the frame comprising the support reels of the roll, which can be reeled in order to unwind the roll, and further a cutter assembly, as a disc, by means of which it is possible to make in the side of the roll at least an incision in horizontal direction. The cutting device is, for instance, used to break up a paper roll, which has been noted to be scrap, whereby the paper material is returned to the pulp process of paper manufacture.
  • Previously known, as devices intended for destroying of a paper roll, are cutting and unrolling tables, onto to which the paper roll is lifted by means of a separate crane. In known solutions space is needed above the table if an overhead crane is used and on the sides of the device, if loading by forklift truck is used for lifting the roll to the device. In known solutions the framework of the device needs space even in all lateral directions. In these as cutting device in the direction of the roll axle a guillotine type cutter, a movable knife or disk cutter is used. Usually in these only an one roll destroying at a time is possible. When the roll is in its ends supported from the axle centre so that it can be reeled, then it is possible to take only one roll to be handled in the device. A Guillotine type cutting flattens the roll by each cutting stroke and the inside bushing of roll also gets damaged unfit for use.
  • WO 93/17946 discloses a mobile load carrier for taking roll up and transporting it beside the cutting machine. The roll can rotate on the load carrier during cutting. The load carrier as fork lift and cutting machine are separate devices.
  • WO 00/62981 discloses an apparatus for emptying reels, as broken paper rolls. A knife is assembled to cut over the roll only in the longitudinal direction forming a layer of paper sheets on a pallet when the roll stays unrotatable.
  • Patent publication US 4,864,906 discloses a machine having a horizontal core-receiving mandrel and a carriage which moves horizontally back and forth above, and aligned, with the mandrel. A freely rotatable cutting wheel is mounted only horizontally moveable on the carriage and is forced downwardly onto paper layers for removing them from a core. The paper roll is unrotatable during the cutting.
  • In order to eliminate the above presented disadvantages a new cutting device according to claim 1 of a reeled up web is developed, by means of which the loading of rolls and simultaneous loading of several rolls into the device and also simultaneous destroying of several rolls are substantially improved.
  • The advantage of the cutting device according to the invention is the small space requirement, since the device itself comprises equipment means for lifting the roll from a wanted direction onto the delivery reels. By means of the loading equipment many rolls one after another can be simultaneously loaded on the reels from a wanted direction. By means of the loading equipment several rolls in a row can be loaded simultaneously onto the reels even if they among themselves would have a different diameter. By means of the tilting joint in the device, the delivery of the bushing left over by roll destroying is done easily. If the frame of the device is furnished with a rotary table the delivery directions of the bushings and the loading directions of the rolls can be selected. Thanks to the rotary function of the cutting device it is also possible to cut off the rolls.
  • In the following the invention is closer described with reference to the enclosed drawing, where
    • Figure 1 shows loading of a roll to the device.
    • Figure 2 shows different roll diameters and the rotary function of the cutting device.
    • Figure 3 shows the tilting of the device.
    • Figure 4 shows the tilting of the device in cutting and loading direction.
    • Figure 5 shows the device from above.
    • Figure 6 shows the cutting device.
    • Figure 7 shows conveying of the layer removed by the device into the refuse chute.
    • Figure 8 shows the rotary table included in the frame.
  • Figure 1 shows frame 1 furnished with wheels 2, resting on which there is the device body 3, which can be tilted and to which, by means of a tilting joint, as supporting elements reels of roll 8 are fixed. By means of the joint as loading equipment plane 9 is fixed to frame 3 and as its extension a plate 10. Plane 9 is turned round for instance by means of a cylinder (not shown), in the same way body 3 around the tilting joint in order to carry out loading. In the frame also a cutting device is fixed upon arms 12. In the ends of arms 12 there is a cross beam 6, where cutting disc 11 is movable. In connection with cutting disc 11 there is a pusher 7, which pusher presses rolls (8',8") of small diameters, which stay put when they are being cut.
  • Figure 2 shows the roll diameter being reduced to size 8' and 8". Arms 12 turn, controlled by the control system, for instance correspondingly by means of hydraulic cylinders. The cutting edge remains in proper position regardless of the roll diameter. Figures 3 and 4 show tilts of frame 3 and the refuse chute 14, into which the paper removed from the roll is conveyed. Figure 3 shows the third support roller 4, which is moved between two outermost solid rollers 4, when the roll diameter was reduced under a certain limit. Figure 4 shows a solution, where there are two rollers 4, the position of which is changed closer to one another, while the roll diameter is reducing.
  • Figure 5 shows the cutting device from above and refuse chute 14 in front of it. Then it is possible to load in the device even several rolls one after another by means of plane 9 and plate 10, when plate 10 is letdown to the floor. There are two support rollers and in the end of arms 12 a cross beam 6 is fixed, to which the cutting device is attached.
  • Figure 6 shows rotating cutting disc 11, where the fastening of cutting disc is made into piece 15 by means of turning gear 16. Thus by means of the device it is possible to make the needed horizontal incision, for instance 20 mm deep in the roll surface by transporting the cutting device controlled by cross beam 6. When the cutting device is turned 90° upward, it is possible by means of it to cut, for instance correspondingly, a deep cutting off incision in the roll surface, while reeling the roll. By means of cutting off the roll it is possible to remove by each horizontal incision narrower parallel strips to be conveyed into the refuse chute. At first, the cutting off must always be carried out before each horizontal cutting. The roll is thus destroyed as 20 mm thick layers from the surface of one roll cycle.
  • Figure 7 is a closer presentation of destroying by cutting off the roll surface in layers. Each layer 13 is conveyed to refuse chute 14 in reeling the roll clockwise by means of reels 4, when the horizontal cutting has been carried out. Rolling of roll 8 is always stopped for horizontal cutting. If there are several rolls with different diameters on the reels, the device cuts at first the biggest ones and when their diameter corresponds to the diameter of smaller ones, destroying them continues simultaneously.
  • If inside the roll there is a bushing, as most often is the case, horizontal cutting must be stopped so that the bushing does not get damaged. The last layers remaining on the bushing are conveyed into refuse chute in unwinding the tail-end of the roll. For this there is in the rotary gear of rollers 4 a quick-rolling speed in order to convey the tail end of roll quickly into refuse chute 14.
  • Figure 8 shows a frame solution, which is attached to the floor by bolts. The frame has a rotary table 17, thanks to which the loading direction of rolls can be selected and correspondingly also the delivery direction of the bushings. The bushings are most suitably delivered in different directions from where the loading takes place.
  • The device can be automated in furnishing it with a control system, which on arrival of the roll to plate 10 begins automatically by means of loading equipment to convey the roll onto rollers 4 and then to destroy the roll in the above described manner. In order to accomplish automated operation, the device measures the diameter, so that the device is able to determine the need of motion of arms 12.
