And the winding side of the taping tape B on the take-up reel C (that is, the taping tape B transferred in the reel core C ′ direction of the take-up reel C is the reel core C ′).
Outside of the side that comes into contact with the take-up reel C (in FIG. 1)
(Above) of the adhesive tape sticking device D.

The taping tape B is continuously taped at a constant speed in the preceding step E, and then passes through a loop through a pinch roller 1, a cutter 2, a detector 3, and a variable guide 4 of a drive system arranged on a base. , The take-up reel C is transferred. The detection unit 3 detects a certain amount of the taping tape B, sends a signal to the pinch roller 1 and the cutter 2, stops the driving of the pinch roller 1 and operates the cutter 2 to cut the taping tape B. ing.

One end side of the cut taping tape B becomes a rear end portion of the taping tape B wound on the take-up reel C, and the other end side cut is nipped by the pinch roller 1. During this time, the taping tape B transferred from the previous step E stays in a loop between the previous step E and the pinch roller 1. The variable guide 4 has a support shaft 5 on the base end side.
With the fulcrum as a fulcrum, the tape is movable up and down in association with the number of windings of the taping tape B, and while the taping tape B is being wound, its tip always leaves a slight gap with the winding peripheral surface.

The take-up reel C is rotatable clockwise by a drive motor (not shown). This take-up reel C is
Any material made of plastic or paper may be used, and a tape having a reel width slightly larger than the width of the taping tape B is used.

It consists of 10 and.

The arm G is movable up and down with an appropriate drive mechanism with its base end as a fulcrum. A folding-back portion 11 for peeling the adhesive tape 6 from the winding tape 8 is formed as a sticking portion at the tip of the arm G, and a pressing member made of an elastic material such as sponge is further provided in front of the folding-back portion 11. roller
12 is rotatably attached from the folded-back portion 11 via a support rod. The pressing roller 12 is attached so that the lower end position of the outer periphery thereof is slightly lower than the level of the folding portion 11. Then, as shown in FIG. 2, when the pressing roller 12 is brought into contact with the reel core C'and the pressing roller 12 is rotated by the rotation of the take-up reel C, the folded-back portion is formed.
The adhesive tape 6 that is peeled off at 11 and transferred is a pressing roller.
It is sandwiched between 12 and the reel core C ', and is pressed by the reel core C'.

It should be noted that the arm body G is always provided with the arm body G on the reel core C'side (the lower side is shown in FIG. 1) by a spring or the like (not shown).
I am trying to urge me. Further, the arm G is formed to have a width dimension to be inserted between the reel side plates of the take-up reel C, and is formed to have a length such that the pressing roller 12 reaches the reel core C '.

Next, the operation of the winding device A for the band-shaped connected body configured as described above will be described together with the manner of attaching the adhesive tape 6.

At the beginning of winding the taping tape B, when the taping tape B continuously transferred from the previous step E passes through the variable guide 4 and approaches the reel core C ′ of the take-up reel C, the adhesive tape is attached. The dressing device D operates.

That is, when the detection unit 3 senses the transfer of the leading end of the taping tape B, the arm G moves downward, and at the same time, the adhesive tape supply mechanism F also operates, and the arm G is inserted between the reel side plates of the take-up reel C. Then, as shown in FIG. 2, when the pressing roller 12 comes into contact with the reel core C ', it is driven to rotate by the rotation of the take-up reel which has started to rotate. At the same time, at the folded-back portion 11 of the arm G, the adhesive tape 6 begins to peel off from the winding tape 8 being transferred, and further peels off as the tape mount 7 is wound up,
One end of the adhesive tape 6 is attached to the pressing roller 12 and the reel core C '. On the other hand, the front end of the taping tape B transferred to the take-up reel C moves at substantially the same level as the peripheral surface top part of the reel core C'on the winding side of the take-up reel, and circles with the peripheral surface of the reel core C '. Contact tangentially.

As the taping tape B is transferred, as shown in FIG. 2, the tip of the taping tape B is provided between the adhesive surface of the adhesive tape 6 partially attached to the winding tape 8 at the folding portion 11 and the reel core C ′. As the parts move and further advance, they are sandwiched between the pressing roller 12 and the reel core C ′, the remaining part of the adhesive tape 6 is adhered to the taping tape B, and the tip part thereof is pressed by the pressing roller 12. It is pressed between the reel core C ′ and the reel core C ′ to fix the tip of the taping tape B (this state is shown by an imaginary line in FIG. 2).

After the attaching process at the beginning of winding is completed, the transport of the winding tape 8 is stopped and the arm G is moved upward to take up the take-up reel C.
Remove it from the stand and let it stand by.

At the end of winding the taping tape B, the detection unit 3
Detects the predetermined number of windings and cuts the taping tape B, the adhesive tape sticking device D operates again. As shown in FIG. 3, the arm G moves downward, the pressing roller 12 comes into contact with the winding peripheral surface which has already been wound around the winding reel C, and is driven to rotate. Further, the adhesive tape supply mechanism F also operates, and the adhesive tape 6 starts to be peeled off at the folded portion 11, and as the tape mount 7 is wound up, one end of the adhesive tape 6 is pressed by the pressing roller 12.
And is pressed while being sandwiched between the rear ends of the taping tape B, and a part of the tape is attached to the rear end of the taping tape B. As the take-up reel C rotates, the remaining portion of the adhesive tape 6 is attached to the take-up peripheral surface of the taping tape B, and the pressing roller 12
And the rear end of the taping tape B is fixed.

After finishing the sticking process at the end of winding, the transport of the winding tape 8 is stopped and the arm G is moved upward to be removed from the take-up reel C, and a winding start sticking process of a new take-up reel is performed. Waiting until This completes the series of winding steps of the taping tape B.

It should be noted that the rotation speed of the take-up reel, the transfer speed of the taping tape, and the transfer speed of the adhesive tape in the above embodiment are preferably synchronized by an appropriate means. Further, it goes without saying that the present invention may be used only at the start of winding or only at the end of winding of the band-shaped connecting body.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

Since the end of the winding start and / or the end of the winding of the band-shaped connecting body can be automatically adhered with the adhesive tape, there is no need for manual work, and the work time can be shortened, the work amount can be reduced, the cost can be reduced, etc. Winding work is improved.

As described above, it is possible to automate the winding of the belt-shaped connecting body itself and achieve complete automation of the series of winding devices.

The adhesive tape feeding mechanism uses the folded-back portion of the arm body tip to remove the adhesive tape from the tape mount and feed it straight out in the tangential direction of the reel core and the winding peripheral surface. Make sure to attach the end. Therefore, a cutter facility for the adhesive tape is not required and the take-up reel can be attached without temporarily stopping the rotation of the take-up reel, thereby eliminating time loss and enabling quick reel exchange work.
