Description

  The present invention relates to a splicer device, and more particularly to a splicer device having a structure suitable for repeatedly executing operations for joining continuous sheets into a continuous material in a very short time.

  In general, a splicer device is a continuous material obtained by repeatedly joining ends of a sheet or roll-shaped resin sheet or paper with an adhesive tape or the like. In addition to a joining unit that repeats the joining operation of sheet-fed sheets, etc., a transport unit that feeds or sends sheet-fed sheets to the vicinity of the joining unit, and a winding unit that winds the joined sheets into a roll. Many of them have units.

  By the way, since the splicer device that joins the sheets together repeats the joining operation many times, it is a problem to realize a device that does not cause defects in the joining portion by increasing the speed of the joining operation. It has become. For example, in the splicer device disclosed in Japanese Patent Application Laid-Open No. 2007-194407, even if the leading edge of the rear sheet is sagging, the sagging portion is sandwiched between the laminating table and the movable table and becomes defective. In order to prevent this, a structure is provided in which a lifting member is provided to lift and hold the suspended portion to the tape application height position.

  However, in this structure, the tape applicator that stores the reel of adhesive tape is gradually advanced along the boundary between the two sheets, and at the same time, the adhesive tape wound around the reel of the tape applicator is suppressed by a roller in sequence. Since it is fed out, it is difficult to increase the feeding speed of the adhesive tape. That is, if the adhesive tape is to be fed out at a high speed, the roller may slip on the surface of the adhesive tape and the adhesive tape may not be pulled out. Alternatively, the tape may tear irregularly when the adhesive tape is cut. In addition, when the operation of the joining unit is speeded up, the peripheral part must naturally support the speeding up. However, this publication does not disclose a structure corresponding to the speeding up. .

  In addition, when sticking adhesive tape on both the upper surface side and the lower surface side of a single sheet, first a web is formed by a splicer device that joins the single sheets, and the roll around which the web is wound is put on another splicer device. It is necessary to set and stick an adhesive tape on the opposite surface with another splicer device. Accordingly, if the adhesive tape is applied to the upper surface side and the lower surface side of the sheet, the throughput is remarkably deteriorated, but the above-mentioned splicer device cannot improve the throughput when it is applied to both surfaces.

In this state, when the tape holding panel 61 moves along the boundary between the two sheets, the adhering roller 76 rolls on the surface of the adhesive tape 80 and the two sheets. The adhesive tape 80 is pasted so as to straddle two sheets by this rolling.

  The cutter 77 is positioned between the tape guide 68 and the tape holding protrusion 67 in accordance with the control of the control unit 17 after the adhesive roller 76 has adhered the adhesive tape 80 to the surface of the two sheets. The adhesive tape 80 is lowered and cut. Further, the vicinity of the lower end of the cutter 77 is a cutting blade protruding in a substantially V shape as shown in FIG. 9 described later. By using the cutting blade with the center projecting in this way, when the cutter 77 is lowered, it starts to come into contact and cut from the vicinity of the longitudinal center line of the adhesive tape 80, and the cut extends simultaneously toward the left and right edges. Will be. Therefore, there is an advantage that the time required for cutting the adhesive tape 80 is shorter than a cutting blade that cuts from one of the left and right edges for the first time toward the other edge. Furthermore, if the adhesive tape to which tension is applied is cut from one of the left and right edges, the cut may run obliquely due to the tension, or the end may become irregular, but this is not the case with the cutter 77 of this embodiment. There is also an advantage that such cutting failure can be prevented. As a result, it is also possible to prevent the tape sticking failure due to the cutting failure. The shape of the cutting blade is particularly preferably substantially V-shaped, but is also preferably substantially U-shaped, for example, and may be a shape combining V and U.

  The tape press 78 has a function of facilitating cutting by pressing the adhesive tape 80 from above when the cutter 77 cuts the adhesive tape 80. Furthermore, it has a function of pressing the adhesive tape 80 against the tape holding protrusion 67 so that the tape holding protrusion 67 holds the adhesive tape 80. In other words, the tape presser 78 is disposed between the cutter 77 and the guide roller 63 c and descends together with the cutter 77 in accordance with the control of the control unit 17. Further, a protrusion is provided at the tip of the tape retainer 78, and when the tape retainer 78 is lowered, the protrusion comes into contact with the tape holding protrusion 67. Since this protrusion is attached to the upper component through a helical spring, when this protrusion abuts against the adhesive tape 80, the helical spring prevents the adhesive tape 80 from being damaged by absorbing the impact. To do. The chuck 70 and the tape adsorbing cylinder 75 are provided independently from the tape holding panel 61, and are not moved by the moving rail 69 unlike those provided integrally with the tape holding panel 61.

  The chuck 70 has a function of grasping and pulling out the vicinity of the end of the adhesive tape 80 attached to the tape holding protrusion 67 with the claw 71. That is, the chuck 70 has an intermediate portion of these claw pieces rotatably supported by the support shaft 74d so that the tip portion of the upper claw piece 71a and the tip portion of the lower claw piece 71b can sandwich the adhesive tape 80. Yes. Moreover, the front-end | tip part of these nail | claw pieces is formed so that it may mutually oppose so that the force pinched | interposed when pinching the adhesive tape 80 may be fully exhibited. Furthermore, the base end sides of these claw pieces are respectively supported rotatably on the support shaft 74b and the support shaft 74c without intersecting. Further, the distal end side of the link 73a and the distal end side of the link 73b are connected via the support shaft 74b and the support shaft 74c. In addition, the base end side of the link 73a and the base end side of the link 73b are rotatably supported by the support shaft 74a. The support shaft 74a is connected to the end of the air cylinder 72. When the air cylinder 72 is contracted, the support shaft 74a is pulled toward the air cylinder 72, so that the links 73a and 73b are also pulled toward the air cylinder 72. Then, since both the support shaft 74b and the support shaft 74c move so as to approach each other, the proximal end portion of the upper claw piece 71a and the proximal end portion of the lower claw piece 71b come close to each other, and the distal end portions that are opposite end portions Leave. When the air cylinder 72 extends, these mechanisms move in opposite directions, so that the tip of the upper claw piece 71a and the tip of the lower claw piece 71b move so as to come into pressure contact with each other. Thus, since the adhesive tape 80 is strongly clamped by the link mechanism, there is an advantage that the force for holding the adhesive tape 80 is stronger than a structure in which the adhesive tape 80 is clamped by, for example, a solenoid. The claw 71 and the air cylinder 72 also have a function of moving to the tape holding panel 61 side with a short distance by a servo motor (not shown).

  Further, a slit 71c is formed at the center of the lower claw piece 71b so as to cut from the tip. The slit 71c is formed in consideration of the length and thickness of the tape holding projection 67 so that the tape holding projection 67 can pass therethrough. Therefore, when the chuck 70 and the tape holding projection 67 approach each other and the tip of the upper claw piece 71a and the tip of the lower claw piece 71b try to sandwich the end of the adhesive tape 80, the tape holding projection 67 is Since the slit 71c of the lower claw piece 71b is passed, the upper claw piece 71a and the lower claw piece 71b do not sandwich the tape holding projection 67. In this embodiment, since the tape holding projection 67 is disposed at a position where it interferes with the lower claw piece 71b, the slit 71c is formed in the lower claw piece 71b. However, the tape holding projection 67 is formed on the upper claw piece 71a. When it is provided at the position where it interferes, a slit is formed in the upper claw piece 71a. Further, when the tape holding protrusion 67 is provided at a position where there is a possibility of interfering with both, slits are formed in both the claw pieces.

  The tape suction cylinder 75 holds the adhesive tape 80 pulled out by the chuck 70. The tape adsorbing cylinder 75 is provided integrally with the tape holding panel 61, and is provided so that it can be moved up and down by an air cylinder not shown in FIG. Further, it is connected to the above-described vacuum pump via a pipe line (not shown), and descends to the pulled-out adhesive tape 80 under the control of the control unit 17, and the adhesive tape 80 has no adhesive. Adsorb the surface. Further, the adhesive tape 80 is lowered until it comes into contact with the surface of the single wafer sheet while adsorbing the adhesive tape 80, and has a function of pressing the adhesive tape 80 against the single sheet. When the tape adsorbing cylinder 75 holds the adhesive tape 80, the chuck 70 is returned to the original position. Therefore, when the sticking roller 76 is sticking the adhesive tape 80, the end of the adhesive tape 80 is held by the tape suction cylinder 75.

  The sticking positioning handle 82 is for adjusting the sticking range of the adhesive tape 80. In the upper tape adhering unit 60 of this embodiment, the tape holding panel 61 moves greatly so as to cross the sheet, and the moving range of the adhering roller 76 provided integrally with the tape holding panel 61 is increased. On the contrary, the movement range of the chuck 70 is made small, but the configuration of the upper tape attaching unit 60 is not limited to this. For example, the tape holding panel 61 is provided with a reel holder 62, guide rollers 63a, 63b and 63c, an end guide roller 66, a tape stopper 64, a stopper receiver 65, a tape holding projection 67, a cutter 77 and a tape press 78. The chuck 70 may be moved greatly so as to cross the sheet. The tape suction cylinder 75 is provided on the tape holding panel 61. In this case, after the chuck 70 pulls out the adhesive tape 80 largely, the tape adsorbing cylinder 75 holds the adhesive tape 80 at a position close to the cutter 77, and after the cutter 77 cuts the adhesive tape 80, the attachment is provided independently. The attaching roller 76 moves toward the chuck 70. Further, both the tape holding panel 61 and the chuck 70 may be moved greatly so as to cross the sheet. In addition, the tape holding panel 61 may be provided with only a function related to the tape holding, and the tape suction cylinder 75, the attaching roller 76, the cutter 77, and the tape presser 78 may be provided on another movable panel. After all, the tape holding panel 61 and the chuck 70 can be relatively separated from each other, and the adhesive tape can be cut and the adhesive tape can be applied as described above. You may modify | change in the range which does not impair.

  Further, the sheet presser 83, the lower tape attaching unit 86, and the sheet feeder 90 will be described.

  The sheet presser 83 prevents the adhesive tape application position from shifting when the upper tape application unit 60 joins the sheets. That is, the sheet presser 83 is provided at a portion where the rearmost end portion of the joined sheets, that is, the vicinity of the rear end portion of the sheet closest to the top plate 41, can be pressed from above by the presser frames 83a and 83b. The positions of the holding frames 83a and 83b can be set to a predetermined position by the sheet pressing positioning handle 84, and the set position can be fixed by the handle stopper 85. Further, a sheet rear end sensor 87 is provided in the vicinity of the sheet presser 83. The sheet rear end sensor 87 detects the rear end portion of the sheet fed from the top plate 41 toward the lower tape attaching unit 86 after completing the joining, and notifies the control unit 17 of the detected result. The control unit 17 calculates the sheet length as a positioning amount for determining the conveyance stop timing based on the detection result of the sheet trailing edge sensor 87, and controls a servo motor (not shown) to The rear end portion of the sheet is accurately stopped at a predetermined position. Therefore, even if there is a variation in the length of each sheet, the positioning amount is calculated based on the detection result of the sheet trailing edge sensor 87, so that there is an advantage that it is not affected by this variation. In place of the sheet rear end sensor 87, a sensor for detecting the front end portion of the single sheet or a sensor for continuously detecting both the front end portion and the rear end portion of the single sheet are provided. The positioning amount may be calculated from the detection result. Further, the position of the guide pin 46c when the guide pin 46c is brought into contact with the rear end portion of the sheet may be detected, and the positioning amount may be calculated from the detection result. In addition, if the length of the sheet is accurately grasped and an operation corresponding to this can be performed, the method for calculating the length of the sheet may be changed as appropriate.

  The lower tape attaching unit 86 has a function of attaching an adhesive tape to the lower surface end portion of the joined sheets. The lower tape attaching unit 86 has the same configuration as the upper tape attaching unit 60 except that the lower tape attaching unit 86 is provided downward with respect to the support table 88. Further, the position of the lower tape attaching unit 86 can be set by the attaching positioning handle 89. Further, the upper tape attaching unit 60 and the lower tape attaching unit 86 simultaneously apply an adhesive tape. That is, among the two sheets on which the upper tape attaching unit 60 is attaching the upper end, the lower tape attaching unit 86 side sheet is simultaneously attached to the lower end. As described above, by applying the upper and lower adhesive tapes synchronously at a position shifted by one pitch, the sheet can be sent out at the same time, and the throughput can be improved. In this embodiment, these tape affixing units have the same configuration, but they may be configured differently as long as the adhesive tape can be affixed to the sheet as described above.

  The sheet feeder 90 sends out a web having adhesive tapes pasted on both upper and lower ends to the outside of the splicer device 10. That is, the sheet feeder 90 is provided with two rollers that are in contact with each other and are rotatable.

  As described above, the single sheets stacked on the magazine base 21 in FIG. 6 are lifted up as shown in the magazine base 22. Then, it is adsorbed by the adsorbing pad 32a or the like, and further moved onto the top plate 41 of the slide table 40 by the elevating air cylinder 34 and the electric cylinder 35, and the state shown in the sheet 16 of FIG. Next, the guide pins 46a, 46b, 46c and 46d push the sheet 16 to the front end side, the guide pins 48a and 48b and the guide pins 48c and 48d operate so as to sandwich the sheet 16 lightly, The sheet 16 is moved to the position shown in FIG. Then, as shown in FIG. 11 (c), the sheet stopper 44 is lowered, and as shown in FIG. 11 (d), the top plate 41 and the like slide toward the support table 79, and the sheet on the support table 79 is displayed. The rear end portion of the leaf sheet 18 and the front end portion of the sheet 16 on the top plate 41 are brought into contact with each other. Next, as shown in FIG. 11 (e), the pressing frames 83 a and 83 b are lowered to press the vicinity of the rear end portion of the sheet 18. Further, in this state, the boundary between the sheet 16 and the sheet 18 is located below the upper tape attaching unit 60, and when viewed from the rear end side of the sheet 16, FIG. The state shown in a) is obtained.

  Subsequently, as shown in FIG. 1B, the chuck 70 is advanced toward the tape holding panel 61. Next, as shown in FIG. 1C, the vicinity of the end portion of the adhesive tape 80 is clamped by the claw 71. Furthermore, as shown in FIG. 2D, the adhesive tape 80 is pulled out to the left side when the chuck 70 returns. Then, as shown in FIG. 2E, the tape adsorbing cylinder 75 is lowered to a position where it comes into contact with the pulled-out adhesive tape 80, and the vicinity of the end of the adhesive tape 80 is adsorbed. Next, as shown in FIG. 2 (f), the claw 71 is opened and the adhesive tape 80 is held only by the tape suction cylinder 75. Subsequently, the tape holding panel 61 is moved to the left by the length sandwiched by the claws 71, and the adhesive tape 80 adsorbed by the tape adsorbing cylinder 75 is shifted to the left. As a result, the tape adsorbing cylinder 75 reliably holds the end of the adhesive tape 80, so that there is no portion that hangs down without being held.

  Further, as shown in FIG. 3 (g), the tape adsorbing cylinder 75 is lowered to a position where it abuts against the sheet 16 and 18, and the end of the adhesive tape 80 is pressed against the sheets 16 and 18, thereby Affix to the sheet. Next, as shown in FIG. 3 (h), the sticking roller 76 is lowered to a position where it abuts against the sheet 16 and 18. Further, as shown in FIG. 3 (i), by moving the tape holding panel 61 to the left side, the affixing roller 76 rolls on the adhesive tape 80 and the sheet 16 and 18, and the adhesive tape 80 Is pasted on the sheet 16 and 18. The pasting roller 76 rolls to a position close to the left end of the sheet 16 and 18, but is stopped before the end.

  Here, the control unit 17 waits for about 0.2 seconds. Immediately thereafter, as shown in FIG. 4 (j), the tape stopper 64 is operated so that the adhesive tape 80 is not loosened. By setting the waiting time, the adhesive tape 80 to which tension is applied by the rolling of the sticking roller 76 is reduced to the original length. Thereafter, the cutter 77 is lowered and the adhesive tape 80 is cut. Further, as shown in FIG. 4 (k), after the cutter 77 is raised, the tape holding panel 61 is moved to the left side. If it does so, as shown in FIG.4 (l), the cut | disconnected adhesive tape 80 will be affixed on the sheet | seats 16 and 18 neatly to the edge part. Next, as shown in FIG. 5M, the holding of the adhesive tape 80 by the tape suction cylinder 75 is released, and the tape suction cylinder 75 is raised. Then, when the tape holding panel 61 is moved to the right side, as shown in FIG. 5 (n), the upper tape attaching unit 60 returns to the state before starting the attaching. At this time, the joined sheet 16 and sheet 18 are sent to the sheet feeder 90 side in FIG. 9 by the length in the longitudinal direction. And the operation | movement which affixes a new sheet | seat sheet on the rear-end part of the sheet | seat sheet 16, and newly affixes the adhesive tape 80 is started. At the same time, the lower tape attaching unit 86 in FIG. 9 also attaches the adhesive tape to the lower end portions of the sheet 16 and the sheet 18. When these pasting operations are finished, the sheet 16 and 18 are further fed out of the splicer device 10 by the sheet feeder 90 as an integral web.

  As described above, in the splicer device 10 according to this embodiment, the chuck 70 first holds the adhesive tape 80, the tape suction cylinder 75 sucks the adhesive tape 80, and the chuck 70 holds the adhesive tape 80. The tape adsorption cylinder 75 is switched to the tape adsorption cylinder 75 and the tape adsorption cylinder 75 affixes the end of the adhesive tape 80 to the sheet 16 and 18, so that the adhesion failure of the adhesive tape end can be greatly reduced. Further, with the tape adsorbing cylinder 75 holding the end of the adhesive tape 80, the tape holding panel 61 is moved to the left, and the affixing roller 76 rolls on the adhesive tape 80 and the sheet 16 and 18. That is, since the adhesive tape is pulled out and pasted separately, even if the movement of the tape holding panel 61 is increased, the adhesive tape 80 is not missed. Further, the pasting roller 76 is stopped before the left end of the sheet 16 and 18, and the remaining portion is pasted after the adhesive tape 80 is cut. Furthermore, since the adhesive tape 80 is cut by the cutter 77 after a waiting time of about 0.2 seconds, there is no occurrence of poor attachment due to the adhesive tape 80 shrinking after cutting. In addition, since the adhesive tape 80 is cut after the tape stopper 64 does not sag, the adhesive tape 80 can be cut cleanly, resulting in poor attachment due to the cut portion running diagonally. Absent. After all, since various measures are taken so as not to cause a sticking failure, various problems that occur with an increase in the speed of the sticking operation are solved. Further, since the upper tape attaching unit 60 and the lower tape attaching unit 86 are operated simultaneously, the process of attaching the adhesive tape to the upper and lower surfaces of the sheet can be completed in a considerably shorter time than the conventional apparatus. it can.

  The present invention is not limited to the above-described content, and includes a touch panel, an elevator, a sheet supply / transfer unit, a slide table, an upper tape attaching unit, a lower tape attaching unit, presence or absence of a sheet feeder, Various modifications can be made to the detailed shape and the like without departing from the scope described in each claim.
