Definitions

  • An automatic web taking-up device has 11 core disposed at one side of the travelling web for taking up [2%] the web a press roller disposed oppositely to the core i 56 R 56 6 at the other side of the web, and a travelling cutter 0 can disposed in series with the press roller at the side where the web is fed into the nip between the input [56] ggfi g gz press roller for cuttingthe web.
  • a compressed air injection tube 11 was disposed at the right side of the sawtooth cutter 10 so as to eject the air from the injection tube 11 in such a manner that the end of the web 12 cut by the sawtooth cutter 10 may wind on the new core 13.
  • the travelling web 12 is cut by the sawtooth cutter l0 rocking around the fulcrum 16.
  • the air is ejected from the injection tube 11 simultaneously with the cutting.
  • the press roller 14 disposed over the new core is rocked around the fulcrum 15 immediately before cutting so as to press against the new core 13.
  • the end of the cut web 12 is wound around the'new core 13 in accordance with the movement of the airinjection tube 11.
  • the new core 13 Since the new core 13 is so rotated as to have the tangential speed in the same direction as the advancing direction of the web 12 immediately before the .web is cut, it functions that the end of the web 12 tends to wind around the new core 13.
  • the compressed air injection tube 11 will be disposed at the right side of the sawtooth cutter 10 after rocking around the fulcrum. 16 and is directed toward the nip A between the press roll 14 and the new core 13. Therefore, the cut web 12 is depressed by the air jet stream ejected from the compressed air injection tube 11 into the nip portion A.
  • the cut web 12 since the web 12 before being cut is travelling, the cut web 12 is not stopped, and the end ofthe cut web l2,is so rotated that the web 12 is nipped by the new core 13 and the press roll 14.
  • the new core 13 has a tangential speed in the same direction as the advancing direction of the web 12 by the. rotation of the shaft l8 and the endof the cut web 12 sometimes passes the nip portion A between the press roll 17 and the new core 13 with the result that the jet stream ejected fromthe compressed air injection-tube 11 impinges upon the web at a point spaced from the endof the cut web 12 whereby it is wound as shown in FIG. 9.
  • the web 12 is folded into the nip A with the result that the end is wound up in the folded condition as shown in FIG. 10, so that the winding becomes irregular. If the winding becomes irregular when there is a photosensitive emulsion layer on the web. it causes a pressure fog. Since the travelling web is shock cut by the sawtooth cutter, the cut end portion is in sawtooth form. Also. this causes the production of wrinkles.
  • the conventional taking-up device having the sawtooth cutter and the compressed air injection tube, even if the paper or thin plastic film becomes folded or wrinkled'at the initial period of the transfer, the folded or wrinkled portion is very small with respect to the overall length and can be ignored.
  • the loss of flatness of the film is a great disadvantage.
  • the conventional device for conducting the method since the conventional device for conducting the method has many disadvantages, it is impossible to automatically transfer the web without stoppage of the web which is not preferable. Due to the irregularity of the surface of the core and to prevent scratches and defects in photographic film the web must be temporarily stopped to wind up the web on the core manually. For this reason, in order to prevent the device from temporarily stopping while the web is transferred, an accumulator for the web is sometimes provided immediately before the taking-up device.
  • This invention contemplates the elimination of the aforementioned disadvantages of the conventional taking-up device, and has as an object to provide a novel web taking-up device which transfers the travelling web from a filled core to new core without stopping it, subsequent to cleanly cutting the web, wrinkling or folding at the end of the cut web.
  • -It is another object of this invention to provide a novel automatic web taking-up device which reliably transfers the travelling web without stopping the web with a simple mechanism.
  • an automatic web taking-up device which has a core disposed at one side of the travelling web for taking up the web, a press roll disposed oppositely to the core on the other side of the web, and a travelling cutter disposed adjacent to the press roll at the side where the web is fed into the nip between the roller and the core for cutting the web.
  • FIG. 1 is a side view of the automatic web taking-up device in the state where the web is wound up according to this invention
  • FIG. 2 is a side view of the automatic web taking-up device in the state immediately before the web is transferred from the filled core to a new core by the automatic web taking-up device of this invention
  • FIG. 3 is a side view of the automatic web taking-up device of this invention in the state where the web is started to be transferred from the filled core to the new core.
  • FIG. 4 is a plan view in the direction shown a-a in FIG. 3;
  • FIG. 5 is a detailed partial perspective view of the web cutter which is an essential part of the automatic web taking-up device of this invention.
  • FIGS. 6 to 9 are side views of a prior art cutting and winding device using a sawtooth cutter, wherein FIG. 6 is a side view of the state of cutting and winding, FIG.
  • FIG. 8 is a schematic view of the winding and FIG. 9 is an explanatory view of the state of winding;
  • FIG. is a side sectional view of the state of the web wound on the roll as a result of the method using the device of FIGS. 6-9.
  • FIGS. 1 and 5 show one embodiment of the automatic web taking-up device.
  • Reference numeral 1 illustrates a core taking up a web
  • 2 is a new core mounted to a turret type web taking-up device
  • 3 is a cutter support arm in the state when the web is taken up by the core 1
  • 8 is a sideadhesive tape adhered to one end of the core 2 in this state.
  • the turret 9 is rotated at the time when a predetermined length of web is taken up on the core 1 and at the same time the cutting and winding device on arm 3 approaches the core 2 so that it becomes ready for cutting and winding as shown in FIG. 2.
  • scratches are great defects in the quality of material such as photographic film, it is a great advantage that in the ready state the web does not contact the core or press roller.
  • the press roller 4 presses the web 12 onto the core 2 after a cutting and winding" signal is given and at the same time the cutter 6 travels along the guide rail 5 immediately upstream thereof as shown in FIGS. 3 and 4 so that the web is severed.
  • the end of the cut web is introduced to the nip portion between the core and the press roller along the guide plate 7 where the end of the web is adhered to the double sided adhesive tape 8 by the nip pressure, and as shown in FIG. 4, the web is adhered onto the core. That is, the cutting and winding operations are conducted in parallel in sequence to each other from one side of the web to the other side with the result that the cutting operation across the width of the web is conducted without stopping the travelling web.
  • a sharp edge cutter is preferred so as notto produce ratio of the feeding speed and the cutter speed.
  • the function required for the double sided adhesive tape prepared previously on the core is to adhere the end of the web to the core. Accordingly, the adhesive tape is not necessary to wind the web around all the periphery of the core end, but may be small piece 8 as shown in FIG. 3. In this case, it is necessary to adjust the timing of the cutter travel so as to coincide with the adhesive tape at the nip portion between the core and the press roller at the edge of the web.
  • the automatic web taking-up device of the turret type since the automatic web taking-up device of the turret type is provided with the cutting and winding device of the present invention, it may clearly take up the web without folds and wrinkles without stopping the travelling web and without any scratches on the web. Thus it is possible to transfer the web from a filled core to new core with the present simple mechanism with safety;
  • An automatic web taking-up device comprising a core, means for mounting said core adjacent one side of a travelling web for taking up the web, pivoted support means disposed adjacent the opposite side of said web, a press roller mounted on said pivoted support means, means for moving said support means to press said web between said press roller and said core, travelling cutter means pivotally mounted on a reciprocable member on said pivoted support means adjacent to said press roller for movement transversely of said web on the upstream side of said roller relative to the direction of travel of said web between said core and said roller and adhesive means secured to said core for securing the leading edge of a cut web to said core for taking up the web.
  • An automatic web-taking-up device as set forth in claim 1 wherein said adhesive means is comprised of a double sided adhesive coated patch disposed adjacent the end of said core from which said traveling cutter means begins its traversing movement.
