(Overall Operation of the First Embodiment) Next, the overall operation procedure of the F-mol tape application machine shown in FIGS. 1 and 2 will be described.

(1) An extruder (not shown) supplies the F-mol W to the F-mol receiving plate 12 of the adherend supplying device 11, and the F-mol W is moved to a position facing the F-mol extruding plate 16 by the engineering plastic conveyor 13. .

(2) When a tape receiving signal is transmitted from a tape sticking device 53, which will be described later, the F-mol extruding plate 16 is operated to send the F-mols W one by one to the right by about 20 cm, thereby expanding the F-mols. Open F-Mall receiving end
It is transported to the right by feed rolls 20, 22, and 24 with a passage confirmation photo sensor through the F-mole guide plate 18 having the 17 and is inserted into the tape guide body 81, and is provided several cm before the F-mole intermediate stopper 86. It stops once it is detected by the photo sensor.

(3) The F-mole intermediate stopper 86 located below the F-mole transport surface protrudes upward from the transport surface.

(4) Upon detecting the stopper protrusion signal, the motor 19 of the feed rolls 20, 22, 24 rotates again, and
The motor 19 stops when the end of the motor abuts against the F-Mole intermediate stopper 86.

(5) The leading end of the double-sided tape is set at the leading end of the F-mol by the tape setting device 52. In other words, this tape setting operation is performed as follows. When the tape core pressing plate 49 advances and holds the rolled tape after the 180 ° rotation operation of the tape replacement rotary table 44 is completed, the advance operation is confirmed and FIG. The lower slider 57 is moved leftward by the air cylinder 56, and the upper slider 65 is further moved leftward by the air cylinder 64 as shown in FIG.
As shown in (B), the lower holding member 72 of the air chuck 66 is provided.
Is elastically pressed against the peripheral surface of the roll-shaped tape T with a constant air pressure.

In this case, the edge scraper 74 of the lower holding member 72 is in contact with the peripheral surface of the tape, so that the tape is easy to be cut, and the tape of the edge scraper 74 is pressed at a constant weak pressure regardless of the size and unevenness of the tape T. In order to make contact with the tape T, constant pressure pressing is performed by a small air cylinder 64 to prevent the tape T from being cut.

The tape T shown in FIG.
Is first rotated in a counterclockwise direction (tape winding direction) to check the colored sandwiched paper b at the leading end of the tape with the photo sensor 78, and then the rotation of the motor 46 is reversed to rotate the rolled tape T in FIG. By rotating in the clockwise direction (tape unraveling direction) as shown in (B), the sandwiched paper b at the leading end of the tape is separated from the tape peripheral surface below the tape by the etch scraper 74, and the upper and lower sandwiched members 71, 72 are separated. The guide is inserted between the tape holding surfaces 71a and 72a.

When the photo paper 76 confirms the sandwiched paper b at the leading end of the tape, the motor 46 is stopped and the air chuck 66 is operated to hold the sandwiched paper b by the upper and lower sandwiching bodies 71 and 72.

By moving the upper slider 65 to the right in FIG. 5, the air chuck 66 is separated from the roll-shaped tape surface, and by further operating the lower slider 57 to the right, the air chuck 66 is moved to the right. After returning to the initial position shown in FIG. 3, the tip end of the tape held by the air chuck 66 is pulled out to the right from the suction cup 91 at the retracted position.

After confirming the return, the air chuck 66 is lowered by the air cylinder 60, and the held tape is fitted into the tape guide groove 82 of the tape sticking device 53.

(6) The tape floating prevention plate 88 is lowered to suppress the floating of the tape, and the suction cup 91 is advanced above the tape and then lowered, and the tape in the tape guide groove 82 is moved to the tape as described above. Lightly press against the cutting receiver 85. At this time, the sandwiched paper b at the leading end of the tape protrudes from the tape guide 81.

(7) Air chuck of tape setting device 52
By opening and raising the 66, the air chuck 66 is separated from the leading end of the tape that is first drawn from the roll-shaped tape.

(8) After confirming the rise, only the leading end pulled out from each roll-shaped tape is subjected to a tape cutting device.
The air scissors 95 are advanced and stopped when the tape position is reached, and the tape scissors 95 cut off the tape tip protruding forward from the suction cup 91 together with the sandwiched paper b. Simultaneously with this cutting, the tape unnecessary for the leading end after the tape cutting is collected in a front storage box by air pressure ejected from a tape chip discharge blower (not shown).

(9) The double-sided tape is vacuum-adsorbed by the suction cup 91 and moved upward. In this case, suction may be detected when vacuum pressure is applied to the suction cup 91 and the negative pressure rises, and the suction pressure may be increased after the suction signal is output.

(10) The tape cutting receiver 85 between the tape and the F-mol becomes an obstacle to stick the double-sided tape T5 to the F-mol W. Therefore, the tape cutting receiver 85 is moved and retracted to the left. In addition, at the time of start, the F-mol W is set by the operation of (4) at this time.

(11) The suction cup 91 is lowered, and the front end of the double-sided tape on which the suction cup 91 has been vacuum-adsorbed is pressure-bonded onto the front end of Fmall W.

(12) The suction force of the suction cup 91 is released by turning off the vacuum pressure, and the suction cup 91 is lifted away from the tape.
The tape receiving shaft 48 on the rotary table 44 is rotated by the motor 46 one or two times in the tape loosening direction (clockwise). By this rotation, the tape T5 is slackened, so that a force for pulling the leading end of the tape affixed on the F-mol W to the left at the start of the F-mol transfer is not generated, thereby preventing the tape from peeling.

(13) The F-mole intermediate stopper 86 is moved down from the F-mole transport surface, and
2 and 24 are started, F-mole W is moved rightward and sent to the pressure bonding roll unit 101a, and the pressure bonding roll unit 101a,
The two-sided tape T is transferred between the upper and lower rubber rolls 103b and 101c while pressing the double-sided tape T against the F-mol W.

(14) When about 10% of the length of the F-Mole is left, the pressing roll units 101a, 101b, and 101c are stopped, and the tip of the F-Mole is locked by the stopper 111 to stop the transfer. At this time, about 10% of the length of the F-mol is in a state where the tape is not pressed.

(15) The tape cutting receiver 85 is moved rightward to be inserted between the unpressed tape and the F-Mold, and the suction cup 91 is lowered to lightly press the tape against the tape cutting receiver 85. This keeps the tape from moving when the tape is cut.

(16) The air scissors 95 of the tape cutting device 94 are advanced and stopped when the tape position is reached, and the end of the tape T is cut by the air scissors 95 so as to match the end of the length of the F molding W.

(17) The stopper 111 is moved down to the lower side of the F-Mold conveyance surface, and the F-Mole W is pressed to the pressure roll unit 101.
Discharge to the right with the force of a, 101b, 101c. At this time, the tape non-pressed portion is also completely pressed.

(18) From the second time onward, the above operations are performed except for the steps (5) to (8) related to the pulling-out operation and the cutting-off operation of the leading end of the tape by the air chuck 66 of the tape setting device 52. Is repeated.

(19) Finally, when one roll of the tape is completed, the suction cup 91 is raised and then retracted, and at the same time, the tape presser 88 is also raised, and the air chuck 66 of the tape setting device 52 is raised.
So that it does not hit the suction cup 91 or the like. The tape core pressing member 49 advances in the tape direction and presses the tape core. After rotating the tape receiving shaft 48 in the counterclockwise direction to wind up the remaining length of the tape (hanging portion), the tape core pressing member 49 is retracted. The rotating plate 45 of the rotating table 44 is rotated by 180 °, and the used remaining tape core is discharged by the tape core extruding plate 50. At the same time, the tape core pressing body 49 moves forward on the new tape side to hold the new tape. I do. Tape setting device
The 52 air chuck 66 moves to the left and grips the leading end of the new tape.

[0098]

According to the first aspect of the present invention, since the adherend and the adhesive tape adhered to the tip thereof are transported while being pressed by the pressure roll device, the entire length of the adhesive tape is applied to the adherend. Can be applied so that the tape surface becomes smooth. In addition, on the long adherend sequentially supplied from the adherend supply device, since the leading end of the adhesive tape supplied from the tape supply device is suctioned and adhered by the tape application device, the tape is used. It does not bend and protrude from the adherend. Furthermore, all the steps relating to the tape application can be automated by the above-mentioned devices and the tape cutting device, and the efficiency can be dramatically improved as compared with the conventional manual tape application work.

According to the second aspect of the present invention, a clamped paper having a color tone different from that of the release paper is attached to the first end of the roll-shaped tape, and the clamped paper is detected by the tape setting device by the photosensor. Since the operation is performed, the leading end of the tape can be securely clamped to reliably take out the first tape. Further, since the sandwiched paper is attached to the tip of the adhesive tape, and the tape setting device grips the sandwiched paper at the tip without clamping the adhesive tape, it is possible to prevent the adhesive tape from sticking to the tape setting device. . Furthermore, the tip of the adhesive tape separated from the peripheral surface of the roll-shaped tape by the sandwiched paper can be easily inserted into the tape setting device. Since the tape setting device can automatically set the leading end of the tape to the tape application device in this manner, the burden and fatigue required for the operator to set the tape can be drastically reduced.

According to the third aspect of the present invention, since a horizontal tape stocker for accommodating a large number of roll-shaped pressure-sensitive adhesive tapes arranged in a cylindrical shape in the horizontal direction is used, even if the number of roll-shaped pressure-sensitive adhesive tapes increases. A load is not applied between the roll-shaped pressure-sensitive adhesive tapes, so that adhesion between the tape side surfaces (pressure-adhesive exuding surface) can be prevented.
