Also, the first spring 23 and the clamp plate 19 are allowed to move only in the horizontal direction, and the claws 20 supporting the auxiliary tape 5 in a pair and the claws 20 elastically move in a direction such that the claws 20 come close to each other. Second spring 21 that is biased by force
And an engaging roller 22 provided on the claw 20 for moving the claws 20 in a direction in which they are separated from each other when the wedge plate 16 is fitted. The clamp means 12 is equipped with auxiliary adjusting means 25. This auxiliary adjustment means 25
Is for adjusting the interval between the claws 20 by expanding or narrowing the claws 20 supporting the auxiliary tapes 5 according to the length of the auxiliary tapes 5 to be used. Slide the clamp plate 19 to the left and right to widen or narrow the clamp plate 19 to which the claw 20 is attached. The threaded rod 27 is screwed to the guide plate 18 and has left and right reverse threads respectively. It consists of In this embodiment, the pressing means 13 presses the auxiliary tape 5 mounted on the main tape 4 from above during the third lowering operation so that the heater 7 heat-welds both tapes together. It is composed of a press plate 24 which is attached to the tip side of and is usually supported by the elastic force of the first spring 23. A heater similar to that on the workbench 6 side may be internally provided on the press plate 24 side.

The moving unit 2 follows the movement of the tape 4 to move the main body 1 with a predetermined stroke width, and an air cylinder 30 that operates at a predetermined timing is used.
The air cylinder 30 is attached to the rail 10 side so as to connect the base 11 side and the rail 10 side, and at least the first lowering operation or the third moving mechanism 3 side.
During the lowering operation, a predetermined pressure does not act on the main body 1 side, and after the auxiliary tape 5 is welded, the clamp plate 15 separates from the main tape 4 or operates at the same time or thereafter to move the main body 1 to the main tape 4 side. It pushes in the direction opposite to the flow and returns to the original initial position.

The drive mechanism 3 is a clamp means 12 of the main body 1 in the initial position.
The auxiliary tape 5 sequentially delivered from the delivery mechanism 6 at a predetermined timing while performing the first lowering operation to the pressing means 13 at a predetermined timing or the third lowering operation.
Is mounted on the main tape 4 side while the main tape is running, and welding is performed while pressure contacting.

That is, the drive mechanism 3 is the first spring described above.
23, the second spring 21, and the third spring 28 have three types of elastic force, and the press rod 14 attached to the base 11 side.
The clamp means 12 and the press means 13 are driven by a delicate balance with the pressure of the air cylinder 31 that pushes the. The press rod 14 is provided with flanges 14a and 14b at predetermined positions on the upper side and the intermediate part side, and the first spring is pressed between the flanges 14a and 14b while pressing the base plate 15 from above. 23 are intervening. The elastic forces F ₁ to F _{3 of the first to} third springs and the pressure F ₄ of the air cylinder 31 are set to have the following relationship.

F ₄ ＞ F ₁ ＞ 4 ・ F ₂ ＞ 4 ・ F ₃ However, there is one first spring 23 in the main body 1,
It is assumed that the same second spring 21 and third spring 28 are arranged at four places.

Next, the operation of the continuous sticking device according to the present invention will be described. It is assumed here that the operation starts from the position where the main body 1 is installed at the initial position in advance as shown in FIG. 2 or is returned to the initial position by the air cylinder 30 of the moving means 2.

(1) First, the auxiliary tape 5 is fed out from the side of a predetermined feeding means and placed on the claw 20 at a predetermined position.

(2) Next, the first lowering operation starts, and the air cylinder 31 operates as shown in FIG. Therefore, the press rod 14 is pushed downward, and the threaded rod 27 supported by the press rod 14 from above is pushed down against the elastic force of the third spring 28 acting via the arm 29. In this way, the press plate 24 side and the clamp plate 19 side descend to a predetermined position, and the clamp plate 19 abuts on the tape 4. Until this time, the wedge plate 16 taper
The portion 16a has not yet been fitted into the engagement roller 22.

(3) Next, the second lowering operation is started, and the air cylinder 31 continues to operate as shown in FIG. Then,
The elastic force of the third spring 23 causes the wedge plate 16 via the base plate 15.
The wedge plate 16 is pressed downward, and as a result,
The taper 16a is engaged with the engagement roller 22 and the guide plate 1 in a state where the pawl 20 is spread out against the elastic force of the spring 21.
I will fit in between 8 and. Therefore, the auxiliary tape 15 supported by the claw 20 is disengaged from the claw 20 and the main tape 4 below.
Mounted on.

(4) At that time, the third lowering operation is started so as to partially overlap with the second lowering operation in time, and as shown in FIG. 6, the air cylinder 31 is further operated to press to a predetermined position. When the rod 14 is pushed down, the descending motion stops. That is, since the elastic force of the first spring 23 acts on the base plate 15 until it is locked to the upper surface of the guide plate 18, the elastic force acts on the wedge plate 16 and reaches the predetermined position.
Is spread. And the base plate 15, wedge plate 16, claws
In this state, the press rod 14 is pressed against the elastic force of the first spring 23 by the pressure of the air cylinder 31, and the press plate 24 presses the auxiliary tape 5 mounted on the tape 4 from above. Press. Here, the pressing operation of the auxiliary tape 5 of the press plate 24 is almost the same time as when the auxiliary tape 5 is disengaged from the previous claw 20, but when the auxiliary tape 5 is disengaged from the claw 20 and the auxiliary supported by the claw 20 is supported. The time may be set so that the tape 5 is pushed out at the same time.

(5) In this way, while the auxiliary tape 5 mounted on the main tape 4 is pressed by the press plate 24 from above, an electric current is applied to the heater 7, and both tapes 4 and 5 are heat-welded. To be done. Since the series of operations from 1 to 5 described above are performed together with the running operation of the tape 4, the clamp plate 19 starts contacting with the tape 4, that is, the predetermined lowering operation. That clamp plate from the time
19 and the press plate 24 are on the tape 4 and the auxiliary tape 5.
The main body 1 follows the tape 4 and moves in the same direction at the same speed during the time from the top to the time of separation.

(6) Finally, if the auxiliary tape 5 is completely welded to the tape 4, the elastic force of the first spring 23 and the second spring 28 acts due to the operation of drawing air from the air cylinder 31. All the members that have descended up to the predetermined state are lifted to a predetermined state, and the work of the third spring 21 narrows the claw 20 to the original state.

(7) At the same time, the air cylinder 30 acts to push the main body 1 back to the initial position.

As described above, one cycle is completed, and the auxiliary tape 5 is welded at predetermined intervals on the main tape 4 running while repeating the same operation.

〔effect〕

As described above, in the continuous sticking device according to the present invention, the clamping means and the pressing means provided on the main body side in the initial position are sequentially driven by the driving mechanism, that is, the third lowering operation is performed by the first lowering operation. The clamp means and the press means descend against the elastic force of the spring 28, and the clamp plate on the side of the clamp means contacts the elongated object. Then, the elastic force is applied in the direction of narrowing the claw by the second descending operation, the elastic force of the second spring is pushed against the elastic force of the second spring, and the claw supported by the claw is removed. Mount on a scale. Furthermore, the action of the elastic force of the first spring is interrupted by the third lowering motion that starts at approximately the same time, and the pressure of the air silling causes the pressure-sensitive adhesive to be adhered to the long object side while adhering both of them. Configured, and these first through third
While the clamp plate and press plate of the descending motion are in contact with the long object or the adhered object, the main body side where they are attached should perform the predetermined work while following the long object in the same direction at the same speed. In this way, since the sticking work of the sticking object can be performed without stopping the traveling operation of the long object, the work efficiency is dramatically improved.

Moreover, according to the continuous sticking device of the present invention, most of the returning operation to the predetermined position after the work is configured to be performed by using the elastic force of the inexpensive spring, which makes it easy. With such a configuration, quick operation can be performed, manufacturing cost can be reduced, and running cost can be reduced, which is extremely effective in practice.
