Definitions

  • the present invention relates to improvements in or relating to a method of and an apparatus for continuously producing small dispensing rolls of thin strips of sheeting, such as paper, film of synthetic resin, wafer, aluminum foil or the like, each roll including a required amount of such thin sheet wound on a core.
  • Rolls of tissue paper may be given as a typical example of a small sheet roll produced by this invention.
  • One method that has hitherto been utilized in producing rolls of tissue paper consists of passing through the core on which the paper is wound a spindle which is of sufficient length to project from said core at both ends. In operation, the end portions of the spindle projecting from the cylindrical member are then rotated so as to wind paper on the outer surface of the core.
  • This method makes it necessary to insert the spindle into the core prior to setting the core on the winder and to remove the spindle from the core wound with paper prior to placing the wound core on a slitter for cutting it into individual rolls of tissue paperv
  • Another method is known wherein a number of rollers are provided between two discs about the periphery thereof. The rollers are rotated and paper is wound on the outer surface of a core supplied between said rollers. It was, however, difficult to wind paper at a high speed by this method.
  • the main object of the present invention is to provide a method of and an apparatus for continuously and automatically manufacturing rolls of a desired length of sheet material by winding the sheet material on a core at a high speed.
  • FIG. 1 is a schematic side view of an apparatus embodying this invention, with certain parts being shown in section;
  • FIG. 2 is a front view of the cylinder drum as seen from one side of the disc;
  • FIG. 3 is a plan view, with certain parts being shown in section, of the cylinder drum, showing the arrangement of the conveyor and nozzles for spraying a bonding agent;
  • FIG. 4 is a schematic side view showing in detail the zone including a standby and first winding position and a second winding position immediately after the sheet has been cut transversely.
  • main shaft 7 suitably supported horizontally has discs 8 mounted centrally thereon.
  • six shafts 9 are supported parallel to the length of main shaft 7 by and between the discs 8.
  • the positions on discs 8 at which shafts 9 are supported lie on a circle which has a common center with discs 8.
  • Rollers 10, all of equal diameter, are supported one on each shaft 9.
  • six compartments I, II, III, IV, V and VI are formed radially at regular intervals by the surfaces of adjacent rollers 10 and the inner walls of discs 8.
  • helical gear 1 1 which is rotatable relative to main shaft 7 (FIG. 3).
  • Said helical gear 11 is formed integrally with a sprocket 12 which engages a chain so as to constantly rotate the helical gear independently of main shaft 7.
  • a helical gear 13 which engages said helical gear 11 so that all rollers 10 mounted on the shafts 9 are continuously rotated by helical gear 11 in a counterclockwise direction at velocities indential with each other and with the velocity of sheet supply.
  • compartments I, II, III, IV, V and VI the walls lying parallel to axis of the cylindrical space are formed by the rotating rollers 10.
  • a pulley 14 is secured to the end of the main shaft 7 and a belt engages said pulley 14 so as to rotate the main shaft 7 in a clockwise direction.
  • An indexing wheel 15 is secured to the end of the main shaft 7 between said helical gear 11 and said pulley 14, said wheel 15 being formed with six notches 15 on its outer circumference for receiving therein an electromagnetically operated stopper 16 so as to control rotation of the main shaft 7 and cause the same to make onesixteenth of a complete revolution each time it is rotated.
  • passage 22 The forward end of passage 22 is at the core supply position 18 in which is mounted member 24 operated by a hydraulic drive 23 which member normally keeps the forward end of passage 22 closed so as to prevent cores 19 from falling from passage 22. It should be noted that continuous operation of conveyor 21 for delivering cores 19 in passage 22 to core supply position 18 causes all the cores in the passage to rotate on their own axes, and this rotation of the cores in the passage is transmitted to cores 19 in bin 20, thereby facilitating movement of the cores successively from the bin to passage 22.
  • member 24 Upon actuation by drive 23, member 24 first moves downwardly from its rest position to a lower operative position in which it opens the forward end of passage 22 and places one of the cores 19 on member 24. Member 24 having a core 19 resting thereon moves upwardly to deliver core 19 to compartment IV now in core supply position 18 and stops in an upper rest position. When member 24 stops in said rest position, the
  • first pressing device 26 consisting of press roller 37, actuator 39 and arm 38 having said press roller 37 at one end and said actuator 39 at the other end thereof.
  • Press roller I 37 is forcibly rotated by means of a motor (not shown) at the speed identical with the sheet supply speed. Said roller presses the core positioned in first winding position 6 against the outer peripheries of two rollers so as to bring it into frictional contact with said rollers, thus ensuring the rotation of the core in the sheet winding direction.
  • a second pressing device 27 is provided at second winding position 17. Said device 27 presses core 19 against two rollers 10.
  • the second pressing device consists of endless belt 29 stretched on a plurality of pulleys 28. Said belt is forcibly rotated at a speed identical with the sheet supply speed or at a slightly higher speed.
  • Sheet 1 is drawn out of sheet roll 2 by means of feed rollers 3.
  • sheet 1 is tissue paper or the like, it is given perforated lines at regular intervals by means of perforator 5 so that it can be easily torn.
  • Sheet 1 is then fed between counter rollers 4 to first winding position 6, where said sheet is wound on a rotating core 19.
  • the length of the sheet to be wound on a core in first winding position 6 is detected by means of counter 30 which is driven by counter rollers 4.
  • drive 23 is actuated by means of controller 35 which operates cooperatively with said counter 30 so that member 24 permits a core to be fed to the compartment in core supply position 18.
  • the clutch (not shown) at the power side engages to rotate main shaft 7 clockwise.
  • Main shaft 7 is rotated at a low speed.
  • the sheet roll is released from press roller 37 of the first pressing device while the core is being moved.
  • the sheet roll is contacted at three points by two rollers 10 and press roller 37.
  • the sheet roll is released from press roller 37 and is contacted at only two points by rollers 10.
  • the sheet roll then enters the second winding position where it is again contacted at three points by the second pressing device and two rollers 10, and sheet is again wound thereon.
  • the sheet roll is released from the pressing devices when it is moved from the first winding position to the second winding position. Consequently, the shortage of the length of the sheet caused by the movement of the sheet roll is made up for by slipping of the sheet roll on rollers 10, thus preventing breakage of the sheet.
  • the fully wound core in the second winding position is dropped onto carry-out conveyor 36 to be moved out of the apparatus.
  • counter 30 driven by detection roller 4 causes hydraulic actuator 31 to actuate so that the sheet is cut by means of knife 32 connected to said actuator.
  • the cutting position should be preferably at a point between the first winding position 6 and the second winding position 17; especially a point immediately behind the first winding position is preferable.
  • winding is begun on a new core being rotated by the rollers 10 and the first pressing device in the first winding position. If the sheet is of strong quality, the cut end thereof will not be easily wound round the core positioned in the first winding position.
  • counter 30 actuating the knife 32 gives a command to a nozzle provided at the first winding position to spray water or a bonding agent onto the core positioned in said winding position, or gives a command for blowing air by means of nozzle 34 against said core from the direction of the second winding position 17, thus facilitating winding of the cut end of the sheet around the core.
  • revolution counter 35 can be replaced by a timer, by means of which the cylinder drum can be rotated a given time after the start of winding on the core in the compartment in the stand-by and first winding position or after the actuation of revolution counter 30 but before the time when the winding of a required amount of sheet on the core is finished.
  • a first pressing device is separated from a second pressing device by a fixed distance and the sheet is supplied from the outside of the core. Consequently, it is possible to start winding on a new core waiting in the first winding position as soon as winding in the second position is finished.
  • the sheet roll on which the required amount of sheet has been wound slips as a result of its being in contact with rollers at only two points, thus preventing breakage of the sheet and facilitating the production of sheet rolls at a high speed.
  • a rotary drum having at least three peripherally disposed and regularly spaced core receiving compartments each constituted by a pair of rotating rollers for frictionally rotating a core;
