Description

  The present invention relates to a roll product manufacturing apparatus that winds a film product to manufacture a roll product, and as an example, relates to a roll product manufacturing apparatus that manufactures a roll product of an optical film product.

  The roll product manufacturing apparatus is a device for manufacturing a roll product by winding a sheet-like film product, and as an example, winding an optical film product used for a large liquid crystal television, a liquid crystal display monitor, etc. Create a roll.

  For the production of a roll product, a winder equipped with a winding core having an adhesive property for winding a film product is used. In general, a twin-screw turret winder provided with a winding core that is reversed around a central axis at a winding position and a standby position is used. As shown in FIG. 8, when the film product F is wound around the core M at a winding position X for a predetermined length to form a roll, the core M is reversed to the standby position Y as shown in FIG. Then, the core M2 at the standby position Y is reversed to the winding position X. And simultaneously with the cutter K cut | disconnecting the film product F, the cut end part of the film product F is adhere | attached on the core M2, and a roll thing is newly manufactured. For example, it is disclosed in Patent Document 1 below.

  When the film product is wound by the winder, the films may come into contact with each other and the film surface may be damaged. Especially in the case of optical films, the product value is greatly reduced if the film product is damaged. Therefore, when winding, another sheet is inserted between the film products, and a film protection product that protects the film surface is inserted. Winding is performed.

In a twin-screw turret winder, when two film products and film protection products are wound at the same time, the adhesive core and the film product are first bonded, the core is rotated, and the film product is wound. In addition, a film protection product is inserted between the film products and wound up.

  In the operation of the winder according to the method, after the winding at the winding position is completed, the film protection product is first cut and removed from the core before the new core is reversed and switched. Then, the core is inverted, and then the cut end of the film product is bonded to a new core while cutting the film product with a cutter. Then, the film protection product is inserted again between the film products, and winding is started.

  In the winding method as described above, each time a roll product is formed, the film protection product must be extracted and inserted between the film products through the film protection product again between the winders. Therefore, it takes time and labor, which is inefficient and affects the operating rate of the roll manufacturing apparatus.

  Accordingly, an object of the present invention is to solve such problems and improve the operating rate of the roll manufacturing apparatus.

In order to achieve the above-described object, a film product is provided by providing a winding core having adhesiveness that is reversed about a central axis at a winding position and a standby position, and rotating the winding core around a horizontal axis at the winding position.

In the roll manufacturing apparatus, a film protection product unwinder 2 is installed in front of the winder 1, and an adhesive material bonding device 3 is installed above the winder 1.

  The winder 1 includes a central shaft 9 supported by a machine casing 8, an arm 10 that rotates around the central shaft 9, a pair of left and right chuck devices 11 at both ends of the arm 10, and the arm 10. The biaxial turret winder is provided with guide rollers 12 that are rotatable on the upper and lower sides. The arm 10 can move the position of the chuck device 11 to a winding position X for winding a film product and a standby position Y by rotating about the central axis 9. The chuck device 11 can hold the core M having adhesiveness and rotate with respect to the arm 10.

  The film protection product unwinder 2 unwinds the film protection product MF by rotating the shaft 13 around a rotatable shaft 13 that holds the film protection product MF. The film protection product MF travels from above the winder 1 to the core M at the winding position X from behind the winder 1.

  As shown in FIGS. 2 and 3, the pressure-sensitive adhesive bonding apparatus 3 includes a rotating shaft 14 that rotates about a horizontal axis, and a guide rail 15 that extends along the rotating shaft 14 above the rotating shaft. The suction bar 16 is movable along the guide rail 15 and has a plurality of opening diameters on the surface, and can be connected to the suction bar 16 via a tube. A suction device 17 for sucking air into the suction bar 16 is provided. The suction bar 16 can rotate around the rotating shaft 14. The suction bar 16 is pulled out along the guide rail 15, a double-sided adhesive tape T that is an adhesive is placed on the surface of the suction bar 16, and the double-sided adhesive tape T is sucked by a suction device 17 and remains in that state. The suction bar 16 is returned to the original position along the guide rail 15. And the said double-sided adhesive tape T is affixed on the surface of the film protection product MF which passes the downward direction of the adhesion bonding apparatus 3 by rotating the adsorption | suction bar 16 centering | focusing on the said rotating shaft 14. FIG. At this time, when the suction bar 16 rotates and reaches the lower side, the suction device 17 stops the suction and peels the double-sided adhesive tape T from the suction bar 16. In addition, the suction device 17 easily peels the double-sided adhesive tape T by sending air from the opening diameter of the suction bar 16 in reverse.

  The film protection product MF delivered from the film protection product unwinding machine 2 passes through the guide rollers G2, G3, G4 from the guide roller G1 provided on the upper part of the film protection product unwinding machine 2, and the adhesive The double-sided adhesive tape T sent from the object bonding apparatus 3 is bonded when passing through the upper part of the guide roller G5. Further, the film protection product MF is guided by the guide rollers G6 and G7, is wound around the near roller 5 and contacts the winding core M located at the winding position X. When the film protection product MF comes into contact with the near roller 5, both films are bonded via the optical film product F sent from below and the double-sided adhesive tape T, and are integrated into the core M. Sent.

  Here, operation | movement of the said roll thing manufacturing apparatus is demonstrated. As shown in FIG. 4, the optical film product F adhered to the film protection product MF via the double-sided adhesive tape T is wound around the near roller 5 on the adhesive core M located at the winding position X. Sent. When the chuck device 11 rotates the winding core M, two sheets of the optical film product F and the film protection product MF are simultaneously wound. At the time of winding, the near roller 5 moves through the shaft 4 and the winding operation is performed while adjusting the position with the film wound around the core M.

  Next, as shown in FIG. 5, when the film is wound around the core M to form a roll, the chuck device 11 is reversed via the central shaft 9. The winding core M rotates counterclockwise to the standby position Y, and the winding core M2 at the standby position Y rotates to the winding position X. During this reversal, the film abuts on the guide roller 12, and the film is kept stretched so as not to cause wrinkles.

  Further, as shown in FIG. 6, when the adhesive core M <b> 2 is newly fed to the winding position X, the pressing roller 7 positioned at the upper portion of the winding machine 1 is moved via the shaft 6 to the timepiece. Rotate around to hold the film from above. Further, along with the operation of the pressing roller 7, the cutter K rotates to the lower part of the film via the shaft 18. Then, as shown in FIG. 7, the cylinder 19 is operated to raise the tip 21 via the shaft 20. The tip 21 is provided with a blade 22 that cuts the film along a horizontal axis and a receiving bar 23 that comes into contact with the film. As shown in FIG. 8, the tip 21 rises and the blade 22 simultaneously cuts the film protection product MF and the optical system film product F. The part to be cut is a part of the double-sided pressure-sensitive adhesive tape T attached by the pressure-sensitive adhesive bonding apparatus 3. The thickness of the part is read by the sensor 24, the cutting part is judged and the cutting part is specified.

  At the cutting end of the roll on the standby position Y side, the chuck device 11 at the standby position Y rotates to wind up the end. Further, the film protection product MF and the optical film product F are integrally bonded to the cut end portion of the film on the winding position X side through the double-sided adhesive tape T. Then, the end portion is brought into contact with the core M <b> 2 at the winding position X by the receiving bar 23 of the rising end portion 21. Then, the cutter K and the pressing roller 7 are returned to their original positions, and the film protection product MF and the optical system film product F are separated by rotating the winding core M2 by the chuck device 11 at the winding position X. Sheets can be taken up simultaneously. By continuing this operation, continuous winding is possible. Further, the completed roll at the standby position Y is removed from the chuck device 11 and a new core having adhesiveness is attached. A roll can be manufactured by this operation.

  As described above, the double-sided pressure-sensitive adhesive tape T is adhered to a part of the film protection product MF, and the film protection product MF and a part of the optical film product F are adhered via the tape T. Sheets can be wound around the core at the same time. And since two sheets can be taken up simultaneously, after winding only an optical system film product around a core first like before, film protection product MF is inserted between optical system film products later. No need to wind up. By doing so, the operation rate of roll manufacture can be improved. And since the location which adheres the double-sided adhesive tape T was made into a part, since the location where an adhesive thing adheres to an optical system film product was reduced as much as possible, the fall of the commercial value of a roll thing can also be prevented.

  Further, the cut end portion of the film cut by the cutter K is an end portion in which the two films are integrated, and the end portion is wound around the core M2 which has been newly inverted, thereby continuously winding the film. It becomes possible to improve the operating rate of roll manufacturing.

  Furthermore, by providing the pressure-sensitive adhesive bonding apparatus 3 so as to move forward and backward along the guide rail 15, an operator can install the pressure-sensitive adhesive on the pressure-sensitive adhesive bonding apparatus 3. The bonding apparatus 3 can be provided by being pulled out from the guide rail 15. By doing so, the operator can be provided with the adhesive without taking an unreasonable posture such as bending the waist forcibly, and the operator's fatigue can be suppressed.

  Moreover, by using the double-sided pressure-sensitive adhesive tape T as the pressure-sensitive adhesive, it is possible to reduce the bonding location between the adhered film protection product and the optical film product. By doing so, the unevenness | corrugation of the surface can be made small in the case of winding, and the probability that a wrinkle will generate | occur | produce in a roll thing by this unevenness | corrugation can be suppressed.

  The adhesion location where the film protection product MF and the optical film product F are adhered is determined by the sensor 24. If the adhesion location can be determined, the core M after the double-sided tape T is adhered is used. The number of rotations may be counted to search for the location, and the location may be cut with a cutter K.
