Abstract

PURPOSE:To reduce residual stress of a tape and to reduce the occurrence of exfoliation of the tape, by a method wherein, in a device which winds an adhesive tape for protection and insulating around the outer peripheral surface of a coil such as reels, the tape is unreeled approximately in the direction of a tangent from a tape reel. CONSTITUTION:Winding of a tape 1 around the outer peripheral surface of a coil 12 is such that after the free end of the tape 1 is clamped by a clamp 14, a moving roller 5 is moved from an imaginary line position to a solid line position to draw the tape 1 in the direction of a tangent from a tape reel 2. In this case, by bringing a one-way rotating roller 6 into contact with the adhesive surface side of the tape 1, the free end part of the tape 1 is prevented from displacement. After the tape is drawn out, the moving roller 5 is moved backward to the imaginary line position, the clamp 14 is moved forward to the left togetherwith a forced press roller 15, the free end of the tape 1 is released, and the free end of the tape 1 is pressed against the outer peripheral surface of the coil 12 by the forced press roller 15 for adhesion thereto. Thereafter, with the coil 12 turned, the drawn-out tape 1 is wound around the outer peripheral surface of the coil 12, and after winding is completed, the free end of the tape 1 is cut in a V-shape by a cutter 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape winding device for winding an adhesive tape for protecting and insulating a coil around the outer peripheral surface of a coil in a relay, an electronic buzzer, or the like.

Conventionally, the tape was wound around the outer circumferential surface of the coil by attaching the free end of the tape to the coil and then letting the coil rotate on its own axis to unwind the tape from the chip reel. The tension required to pull out the coil was applied directly to the tape wrapped around the coil. However, this tension was so large that residual stress remained in the tape wrapped around the coil, causing the tape to peel off over time, causing the tape to peel off over time. In addition, in the past, after wrapping tape around a coil, the tape was cut with a cutter that had a saw-blade shape or a straight line. Both ends were easy to separate from the coil. Furthermore, in the past, in order to attach the free end of the tape pulled out from the tape reel to the coil, the free end of the tape was placed on an elastic body narrower than the coil bobbin, and a vacuum suction was applied to the elastic body. A cat hole (7ils) is provided, and the free end of the tape is attached to an elastic body using vacuum suction to position it, and the elastic body is pressed against the coil to attach the free end of the tape to the coil. Once the tape was cut, the tape that had fallen naturally was attached to the elastic body again using vacuum suction, but in this case, the width of the elastic body was narrower than the width of the coil bobbin, so the tape was attached to the elastic body using fucoid. The disadvantages are that it is difficult to form a straight line, the position of the piece tends to shift when it falls naturally after cutting the piece, and the tape tends to meander.
Tapes with weak contact strength have the disadvantage that the free end is not easily attached to the coil, and the coil tends to spin idly when the coil rotates on its own axis.

This product was developed in consideration of these points, and its first purpose is to provide a tape winding device in which the coil of the wound tape is unlikely to come off. The second objective is to create a tape wrapping system that will ensure that the tape is stuck to the coil without causing the tape to wind in a meandering manner or causing the coil to spin idly. It is on offer.

The present invention will be described below. The present invention includes a pull-out means for pulling out a tape from a cheese reel in a substantially tangential direction thereof, and a pressure-adhering method for adhering the tape pulled out by the pull-out means to the outer circumferential surface of a rotating coil. a cutting means for cutting the tape into a V-shape with a concave center at its free end; and a clamp for clamping the free end of the tape and attaching the tip to the coil together with the suppressing means. The above object has been achieved by each of these configurations, and will be described in detail below based on the illustrated embodiments. In the figure, [11 is tape, (

A movable D-rail (5) serving as a pull-out means is located below this hinge lever (2) and is housed in the board f31. This movable roller (5) is driven to move in left and right horizontal directions. A rotary roller (6) is disposed below the movable roller (5) and is in contact with the sticky side of the tape (+). Substrate (3
) The rotating roller (6) attached to K is designed to be able to rotate only in one direction π and not in the opposite direction, and since the adhesive side of the tape (1) is in contact with it, the contact area is small. A plurality of grooves (7) are formed on the outer circumferential surface of -! Coated with fluorinated ethylene resin. Further below the rotating roller (6) is the substrate +31.

The guide rest (9) has a kite groove (lO) on the side surface for kiting the tape (l), and is rotatably supported at the bottom of the fucoid plate (101) and connects with the bottom of the guide groove (lO). A rotating pin (Il) that forms a passage gap of +1 tape is installed between them.

When winding the chain (1) around the outer peripheral surface of the coil (12), the free end (1) of the chain (1) shown in the figure must be

Next, by moving the board (3) upward, the chip (1) is pulled out a little from the tape reel (2), and then the movable roller (5) is pulled out from the tape reel (2).
) from the position shown by the imaginary line in the figure to the position shown by the solid line, the tape (1) is pulled out from the tape reel (2) in a substantially tangential direction. Here, when pulling out Chi-5 (+), the reason why the Chi-5 (+) is pulled out in a substantially tangential direction is because the angle β between the Chi-5 reel (2) and the pulled-out tape (+) as shown in Figure 2 is large. This is because the more the cheese (1) is pulled out in the 1 direction, the easier it is to curl. Also, at this time, the rotating roller (6), which rotates only in one direction, comes into contact with the adhesive side of the chip, causing the chi':5+
This prevents the free end of the ++ from shifting. When the chi "j" (1) is pulled out in this way, the movable roller (6)

The amount pulled out from 2) is wound around the outer circumferential surface of the coil (12) while being guided by the coil (9).In this way, when the winding of the coil (1) is completed, , the cutter (13) moved forward to the left in the figure, moving the tip (+) under tension between the rotary pin (11) and the seventh coil (02).
) cuts, cutter 03! After the coil (1
2j is driven to rotate at an angle, and the winding end of the tape (1) is pressed against the outer peripheral surface of the coil (1). The work is completed when the roller (15) retreats.Then, the end of the tape (1) I''i wound around the coil (12j) is the cutter (!3).
It has a V-shape with a convex center due to the shape of the tape (
1) Each angle α at both ends of the end of the winding is large,
For this reason, the floating from the coil (1) at both ends is small,
After being peeled off, the free end of Q (11) is guided by the rotating pin (llj) and the work begins It maintains the same 1rt as before.

As mentioned above, in the specific source IIIEI, since the tape once pulled out from the tape reel can be applied to the coil, the tension when applying the tip to the coil is small, and the residual h'I stress is also low. Because of its small size, the end of the tape once wound around the coil does not come loose from the coil, and since the tape is pulled out from the tape reel in a substantially tangential direction to the tape reel, there is no chance of the end of the tape coming off the coil. The residual stress is very small, and there is no floating or peeling.In addition, due to the shape of the end of the winding of the tape on the coil, the shape of the cutting means that cuts the tape causes little floating on both ends, and from this point of view, This will eliminate any peeling. In addition to the above-mentioned effects, the combined light I8!1EIK eliminates the possibility of meandering of the tape during winding because the chain is kited, and the free end of the tape is clamped by the clamp. In order to be able to stick it to the coil, the free end of the tape and the suppressing means ♂ can be firmly attached to the coil without causing any meandering of the tape even when starting winding.
The coil does not idle, and the tape can be wound reliably.
