Definitions

  • the present invention relates to a winding machine, and more particularly to a winding machine for winding a web material around a core tube to producing a wound roll thereof.
  • Winding machine is commonly used in the pulp and paper industry and textile industry for producing smaller diameter logs or rolls of web material from large diameter parent rolls.
  • winding machines are used in the paper converting industry to produce rolls of toilet paper, kitchen towel and the like.
  • a conventional winding machine is provided with a presser which has a surface with high coefficient of friction and which exerts a pressure to impede the forward movement of the web material. This results to the tearing off of the web material.
  • a severing means having sharp, saw-toothed blades is used to sever the web material.
  • U.S. Patent No. 5,979,818 discloses a rewinding machine for the formation of logs of web materials.
  • the closess prior art is considered to be represented by the device disclosed in WO01/64563A .
  • a material-severing device is provided for severing the web material when the winding of web material is completed.
  • Either the presser or severing means has to work with a stroke and timing control device, such as an automatic timing control roller, an automatic timing control cam or linkage assembly, etc.
  • the presser is driven to act on the web material at a predetermined severing timing by the stroke and timing control device, such as at pressing timing or clipping timing.
  • a stroke and timing control device such as an automatic timing control roller, an automatic timing control cam or linkage assembly, etc.
  • a primary object of the present invention is to provide a web material winding device which is able to tear a web material by arranging a transporting passage.
  • the transporting passage has a dimension that is slightly smaller than the diameter of the core tube.
  • the new core tube conveying on the transporting passage presses on the web material, generating an interference to the speed of the web material and causing the tearing of the web material. No presser or severing means is needed for severing the web material.
  • Another object of the present invention is to provide a winding machine that tears the web material to complete a roll whenever a new core tube is delivered to the transporting passage. No timing control device is needed for controlling the tearing of the web material.
  • the present invention provides a web material winding machine as defined in the claims that follow.
  • the winding machine comprises a core tube storage tank, a guiding unit, a transmission means, a web material feeding assembly, a gripping assembly and a second gluing mechanism.
  • a core tube is glued with initial glue and conveyed from the guiding unit to the transmission means. Meanwhile, the web material is fed by the web material feeding assembly to the transmission means at a normal speed.
  • the transmission means pushes the core tube to move through a transporting passage to the gripping assembly and the web material is stuck to the core tube.
  • the web material winds around the core tube at the winding region.
  • a new core tube is conveyed to the transporting passage and interferes the speed of web material, causing the web material to tear along the perforation line.
  • a tail glue is applied to the completed core tube by the second gluing mechanism and a roll is produced.
  • FIG. 1 is the schematic view of a web material winding machine constructed in accordance with a preferred embodiment of the present invention.
  • a web material winding machine 100 is adapted to wind a web material 200 to a core tube 300.
  • the winding machine 100 includes a core tube storage tank 1, a guiding unit 2, a transmission means 3, a web material feeding assembly 4, a gripping assembly 5 and a second gluing mechanism 6.

  • the gripping end 512 is pivoted at the fixed end 511, such that the gripping end 512 is movable along a second oscillating orbit II as shown in Fig. 3 .
  • the gripping roller 52 is mounted to the gripping end 512 and is adjacent to the first roller 321 and above the third roller 323 for gripping the working core tube 300a.
  • a winding region 53 is defined among the first roller 321, the third roller 323 and the gripping roller 52.
  • FIG. 2 is an exploded perspective view showing a second gluing mechanism of the web material winding machine of Fig. 1 .
  • the second gluing mechanism 6 is arranged adjacent to the third roller 323 and tilts downward.
  • the second gluing mechanism 6 includes a cover plate 61, an injector 62, a glue supply 63 and a casing 64.
  • the cover plate 61, the injector 62 and glue supply 63 are aligned with each other and are piled together from top to bottom in sequence.
  • the casing 64 is fastened to the plate 61 by screws for accommodation and protection of the injector 62 and glue supply 63 therebetween.
  • the cover plate 61 is perforated with a plurality of apertures 611.
  • the injector 62 is provided with a support base 621 and a plurality of injecting needles 622. Each of the injecting needles 622 aligns with an aperture 611 located above.
  • the glue supply 63 comprises a support base 631, a plurality of tubes 632 and a plurality of ducts 633.
  • the tubes 632 are supported on the support base 631.
  • Each of the tubes 632 is connected with a duct 633 which is aligned with an injecting needle 622 above the glue supply 63.
  • the tubes 632 contain glue and supply the glue through the ducts 633 to the injecting needles 622.
  • FIG. 3 is a schematic view showing the delivery of core tubes to the guiding unit of the web material winding machine of Fig. 1 .
  • the core tubes 300 are delivered one by one from the core tube storage tank 1 through the guiding passage 21 to the platform of the pushing mechanism 23.
  • the first gluing mechanism 22 of the guiding unit 2 applies initial glue to the core tube 300.
  • Fig. 4 is a schematic view showing that the core tube is conveyed to the transmission means 3 of the web material winding machine.
  • the glued core tube 300 is pushed forward by the retractable arm of the pushing mechanism 23 along the platform to the transmission means 3.
  • the web material 200 is conveyed through the web material feeding assembly 4 to the roller assembly 32.
  • the blades 421 of the perforation roller 42 works with the counter blade 411 of the counter roller 41, producing a line of perforations across the web material 200.
  • Fig. 5 is a schematic view showing that the core tube is conveyed to the transporting passage of the transmission means.
  • the feeding arm 31 oscillates around the fixed end 311, and accordingly, the pushing end 312 moves along the first oscillating orbit I. It can be seen from Fig. 5 that the pushing roller 313 pushes the core tube 300 to displace into the transporting passage 34.
  • the transporting passage 34 has a width slightly smaller than the diameter of the core tube 300. Therefore, when the core tube 300a is conveyed along the transporting passage 34, the core tube 300a is squeezed to oval shape.
  • Fig. 7 is a schematic view showing that the working core tube 300a reaches the winding region 53 of the gripping assembly 5 and is gripped by the gripping arm 51. At the same time, the feeding arm 31 swings back to its original position.
  • the working core tube 300a is driven to rotate to wind the web material 200 at the winding region 53.
  • the first gluing mechanism 22 applies initial glue to a new core tube 300.

  • the control means may be any conventional control device that can be preset with various operation parameters, e.g. the timing of release of core tube from the guiding unit 2.
  • Fig. 9 is a schematic view showing the new core tube 300 is conveyed to the transmission means 3.
  • the glued new core tube 300 is pushed forward by the arm of the pushing mechanism 23 along the platform to the transmission means 3.
  • the working core tube 300a at the winding region 53 keeps on winding at the normal speed.
  • Fig. 10 is similar to Fig. 3 .
  • the new core tube 300 is pushed to enter the transporting passage 34 by the feeding arm 31. Once entering the passage 34, the core tube 300 contacts the web material 200 and sticks the web material 200 by the initial glue, forming a new working core tube 300a.
  • Fig. 11 a schematic view showing the new core tube presses on the web material feeding to the winding core tube.
  • the new core tube 300a moves through the transporting passage 34 and is squeezed to become oval shape.
  • the new core tube 300a presses on the web material 200, and therefore, the new core tube 300a interferes the movement of the web material 200. This interference action slows down the feeding speed of the web material 200 or even stops the feeding of the web material 200 to the working core tube 300a.
  • the working core tube 300a at the winding region 53 keeps rotation at its normal speed.
  • Fig. 12 is a schematic view showing the tearing of the web material.
  • the pulling force causes the web material 200 to tear along the perforation line.
  • the winding of the working core tube 300a is completed and a roll 400 is produced.
  • Fig. 13 shows that the roll 400 leaves the winding region 53 and the new core tube 300a is conveyed to the winding region 53.
  • the second gluing mechanism 6 tilts downward, the roll 400 leaves the winding region 53 and rolls across the cover plate 61 of the second gluing mechanism 6.
  • the second gluing mechanism 6 injects tail glue through the apertures 611 to the web material 200 of the roll 400.
  • the web material 200 is adhered by the tail glue to the roll 400.
  • the processing to the roll 400 is accomplished.
  • the injection of the final glue by the second gluing mechanism is also controlled by the control means. Meanwhile, the new working core tube 300a is conveyed to the winding region 53.
  • the control means drives the injector 62 and the glue supply 63 to lift up such that the injecting needles 622 reaches the apertures 611 and are close to the roll 400, and injecting needles 622 inject tail glue to the roll 400.
  • the injector 62 and the glue supply 63 returns to its original position.
  • the upward and downward movement of the injector 62 and the glue supply 63 are achieved by a retractable lifting device.
  • the lifting device may comprise spiral pins, springs or other effective elements.
  • the tearing of web material is achieved by the interference of the new core tube to the working core tube.
  • the winding machine tears the web material whenever a new core tube is delivered to the transporting passage.
