Description

  The present invention relates to a double-sided tape in an apparatus in which a series of long thin films wound in a roll shape are crimped to a shaft prepared separately with a double-sided tape and wound at a constant length to cut. With regard to the pressure bonding method to the shaft and the film fixed winding method to the shaft, by adding unique ideas based on new ideas, various problems related to pressure bonding of double-sided tape that have been unavoidable with a certain probability until now, It is intended to eliminate the problems related to the vertical wrinkles at the time of the tape winding and the slow inclination of the film winding mountain in the left-right direction.

At present, there is an apparatus of Patent Document 1 in which a long thin film is cut into a certain length and its starting point is pressure-bonded with a double-sided tape and is wound around a shaft. At this time, the double-sided tape is cut in advance along the length of the shaft together with the release paper, and after pressing it onto the shaft, the release paper is peeled off, the film starting point is pressed against it again, and then the shaft is simply rotated. This is a method of winding a film. In addition to this device, as a measure to prevent wrinkling when a film is wound on a shaft at a fixed length, Patent Document 2 in which a fixed-length winding is performed while directly pressing a roller having a slightly thicker central portion than both ends against the shaft. There is. In addition, I am not aware of non-patent literature related to this.

  In a series of operations in which roll-shaped thin films of thousands to tens of thousands of meters delivered from a material manufacturer are wound around shafts while being cut to a certain length, the existing Patent Document 1 With regard to the following two points in equipment, measures to solve it are insufficient or no measures are taken, and since it is an automatic machine for mass production, prevention of the following problems is unavoidable artificially, A certain percentage of defective products inevitably occur. The first problem is that the double-sided tape is cut to a certain length together with the release paper, and the release paper is peeled off after being crimped to the shaft. The problem of partial folding occurs. Secondly, increasing the film winding speed increases the torque of the shaft, increases the tension applied to the film, and tends to cause vertical wrinkles on the film. It is that you are. In addition, as in Patent Document 2, which is different from this, a method in which a roller having a thicker central portion than both ends is directly pressed against the shaft while applying pressure is applied to the shaft itself depending on the material and diameter of the shaft. The rigidity is different. Therefore, in order to guarantee the effect of this method, it is necessary to prepare / replace a dedicated roller whose curve is changed each time according to the material and diameter of the shaft, which is inferior in versatility. In addition to the above problems, when the film is wound around the shaft, there is a problem that the film winding thickness increases and the film winding peak may gradually tilt in the left-right direction of the shaft.

In order to solve this problem, the present invention relates to an adhesive sheet portion of a double-sided tape and a release paper in advance when a double-sided tape for fixing the starting point of the film is pressure-bonded to the shaft when a film is wound around a shaft. And cut only the adhesive sheet part to a certain length and then affix it to the shaft. In conjunction with this, the used release paper is taken up in a continuous manner without being cut. First, the sizing cut of the pressure-sensitive adhesive sheet portion is performed on a platform to which a silicon plate is attached using the property that the pressure-sensitive adhesive sheet portion does not adhere firmly. Next, the pressure-bonding operation of the pressure-sensitive adhesive sheet portion to the shaft is performed by a control block that is arranged on the platform and interlocks vertically and backward. A number of small holes are made in the bottom of this control block with a silicon plate attached, and the use of air intake / exhaust from there makes it possible to regulate the position of the adhesive sheet that has been cut in size, to maintain the shape, to move to the shaft. Perform transfer.

Also , when winding a thin film around the shaft, rotate it while holding both ends of the shaft, and when wrapping the film around the shaft, air is concentrated and vertically directed toward the center of the shaft in the longitudinal direction. Adopt a spraying method. The air jetted toward the center of the shaft flows separately in the left-right direction while pressing the film against the shaft. By using this air flow force, the generation of wrinkles is suppressed and corrected, and the film is wound.

In addition , when winding a thin film around a shaft, the end of the shaft can be moved back and forth without interrupting winding when rotating the film while holding both ends of the shaft and winding the film around the shaft. adopt. As soon as the surveillance camera recognizes that the peak of the film that increases in thickness on the shaft as the shaft rotates begins to gradually tilt in either the left or right direction of the shaft, the center of the shaft in the longitudinal direction is the center. While maintaining, the slow tilt is suppressed by slightly moving the both ends of the shaft back and forth with respect to the film supply direction, and the film is wound.

  The method of separating the adhesive tape part and release paper before pressing the double-sided tape on the shaft winds up the used release paper in a continuous manner, thus completely eliminating the problem of shaft release paper removal failure. Eliminate. In addition, the problem of overlapping of the adhesive tape part and the end part of the adhesive tape that occurs when the release paper is removed is solved. In addition, when a thin film is wound around a shaft, the problem of vertical warp occurrence of the film is corrected and suppressed by a system in which air is intensively injected toward the center of the shaft. As a result, it is possible to increase the shaft rotation torque for film regular winding, and as a result, it is possible to increase the winding speed to about twice the speed of existing equipment. Furthermore, the use of air jets creates a synergistic effect of suppressing the entry of cotton dust and fine impurities. In addition, when winding a thin film around a shaft, it is possible to wind the film by using a method in which both ends of the shaft are slightly moved back and forth with respect to the film supply direction around the center in the length direction of the shaft as the shaft rotates. The problem of slow tilting of the mountain in the left-right direction is corrected and suppressed, and it is greatly eliminated.

The following are examples of the present invention up to a fixed size cut of the pressure-sensitive adhesive sheet. The double-sided tape roll 2 set on the double-sided tape supply board 1 is separated into the adhesive sheet 4 and the release paper 5 after passing through the relay pulley A 3 in advance. The release paper Yuku taken automatically around the winding Toban 7 via the relay pulley B 6. In conjunction with this, is sucked by suction from the intake pores A9 on platform A 8, the adhesive sheet was waiting state is, the intake of the intake and exhaust pores A is in synchronization with the change in the exhaust, the control block A rises away from the platform a is pulled to the control block B 14 with is sucked by the intake from the intake pores B13 of the bottom surface of 12. Then, the control block B Slide the drawing back direction by rails A15, pull an adhesive sheet on the platform B 10 over. (State in FIG. 1) Next, the control block A is lowered until it hits the platform B, and intake of the intake and exhaust holes B is stopped. Synchronously with this, the pulley A is lowered, and intake is started from the intake / exhaust hole A of the platform A, and the adhesive sheet is in a straight line on the platforms A and B. Next, the cutter 11 is raised and cut from the gap between the platforms A and B, and the fixed-size cutting of the adhesive sheet is completed. (See Figure 1)

The following are examples of the present invention up to the completion of the shaft crimping of the fixed-size cut adhesive sheet. The platform B, to which the prepared adhesive sheet 16 that has been cut to a fixed size is attached, slides on the rail B17 from the left to the right in the drawing. In synchronization with this, the control block C 19 and the control block D 20 slide on the rail C 21 from the right to the left of the drawing to the position just above the platform B. (State in FIG. 2) Next, the shaft 18 previously held in the control block C is pushed down until it hits the platform B. Then, the shaft is slightly rolled to the left and right on the prepared adhesive sheet, and the crimping of the prepared adhesive sheet to the shaft is completed. (See Figure 2)

The following are examples of the present invention up to the crimping of the prepared shaft 23 on which the double-sided tape has been crimped and the leading end of the original roll of film 22. This is a basic structure in which a control stage A 25 and a control stage B 28 that move up and down are arranged on a base board 24 , and a cutter 31 is arranged in a central gap. The tip of the thin film supplied from the long original roll is sucked and stayed on the control stage A by the intake air from the intake / exhaust hole C27. From there, the prepared shaft that has undergone double-sided tape pressing is supplied in parallel from the upper right side of the drawing to the left side, and is stopped above the urethane rubber sheet 26 at the right end of the control stage A. Then, it is lowered and rolled slightly to the left and right while pressing against the urethane rubber sheet, and the double-sided tape on the shaft and the tip of the film are pressed. (See Figure 3)

The following are examples of the present invention up to the completion of standard winding by winding a film around a shaft that has been crimped to the film tip. The control stage A 25 is lowered to the level of the control stage B 28 in a state where the prepared shaft 23 that has undergone the film front end pressure bonding is held from the left and right. Then, the prepared shaft is slid from the left to the right in the drawing right above the injection hole 30 and then lowered to a level lower than that of the guide roller 32 . Then, while the air is vigorously jetted vertically from the injection hole toward the central portion of the prepared shaft just above, the prepared shaft is rotated at a high speed to wind the film, and a constant winding is performed until the film becomes a certain length. (See Figure 4)

The following is an example of the invention of the present application from the preparation of the next prepared shaft 32 to the cutting of the film 22 after the regular winding has been completed until the work is completed. When the film of a certain length has been wound, the control stage A 25 is raised again to the highest level of the guide roller 29 . Next, the next-prepared shaft is slid from the upper right side of the drawing to the left and supplied. Stop and stay as it is just above the exhaust port C27. Air is sucked in from the exhaust port C, the film is firmly fixed, the cutter 31 is lifted in a state without slack, the film is cut (the state shown in FIG. 5), and the rear end of the film is continued while air is being injected from the injection holes 30. Finish winding neatly. Finally slide the next prepared shaft in the stay until the urethane rubber sheet 26 over to complete the work of a series. This series of work is defined as one cycle, and the same work is repeated. (See Figure 5)

The following are examples according to the present invention . Axis A34 The control block E 33 which faces to sandwich the base plate 24, the control block F 35 incorporates Axis B36, when fixed-length winding of the film 22 to the prepared shaft 23, - the axis A It is a basic structure in which the film is wound by rotating it with a motor while holding the left and right sides of the prepared shaft in B. At this time, a monitoring camera 37 set in the center of the control block E / F, in the upper right of the drawing, monitors the gradual tilting of the mountain of the film being wound. When it is sensed that slow tilting has started in either the left or right direction, an electric signal is immediately sent, and the left and right axes A and B are synchronously moved back and forth in synchronism with the prepared shaft. A fixed position is always maintained with the central part in the length direction of the prepared shaft as the central axis. If the left end of the film is recognized as being tilted to the left, the left end of the shaft comes forward, and at the same time, the right end is retracted backward. At the same time, the left end is moved backward by the same size, thereby suppressing the gradual inclination of the film winding crest. (See Figure 6)
