JPH061543A - Take-up roller for top tape - Google Patents

Abstract

PURPOSE:To simplify the top tape winding work of a top tape winding roller taking up the top tape of taping parts. CONSTITUTION:The device is made up of a roller A2, and of a freely separable roller B3 wherein a cylindrical and elastic spacer 8 in a wave shape is provided for the outer circumference of the winding barrel section 7 of the roller A2. When a top tape 6 is extracted after the top tape 6 has been taken up, the top tape 6 can be extracted at once from a top tape take-up roller 1 with ease, because the winding pressure of the top tape 6 is decreased with the outer wheel of the top tape 6 pressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top tape winding roller for collecting a top tape of a taped electronic component or mechanical component.

[0002]

2. Description of the Related Art A conventional roller for winding a top tape of a taping component has a structure as shown in FIGS. 6 and 7, for example.

That is, after the top tape 6 is peeled from the taping component (not shown), the top tape 6 is removed.
The top tape winding roller 61 for winding the
A roller A62 having the same width as the top tape 6 and having a flange A64 for guiding one side of the top tape 6, and a roller B65 having a flange B65 for guiding the other side of the top tape 6. The roller A62 and the roller B63 can be integrated or separated by a connecting means (not shown). Further, the end of the top tape 6 and the winding body of the top tape take-up roller 61 are connected by the adhesive tape 66 as shown in FIG. 6, or the winding body of the roller A72 as shown in FIG. The connection is made using the groove 72a provided in the.

[0004]

However, the above conventional techniques have the following problems. That is, when the top tape 6 is wound up and the top tape take-up diameter reaches the take-up limit where the diameter is larger than the diameter of the flange A64 that serves as the top tape take-up guide, the top tape take-up roller A6 is reached.
When trying to restore 1 to the initial state again, due to the winding pressure of the top tape 6, the top tape 6 cannot be pulled out from the top tape winding roller 61 at a time, and the top tape 6 is gradually pulled from the tip thereof. I had to solve it.

Therefore, it has been necessary to spend a lot of time for the wasteful work of pulling out the top tape 6 from the top tape winding roller 61. The present invention has been made in consideration of the above conventional problems, and an object of the present invention is to provide a top tape winding roller that can easily wind a top tape.

[0006]

In order to achieve the above object, the present invention comprises a pair of separable roller portions having guide portions for guiding both sides of the top tape, and a winding cylinder of the pair of roller portions. A cushioning material is applied to the outside of the part.

[0007]

In the above structure, when the wound top tape is removed, the cushioning material contracts by pressing the outer ring of the top tape to reduce the winding pressure of the top tape,
The top tape can be pulled out from the top tape winding roller at one time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. As shown in FIG. 1, the top tape winding roller 1 includes a roller A2 having a flange A4 for guiding one side of the top tape 6 and a roller B3 having a flange B5 for guiding the other side of the top tape 6. Is configured next to.

The winding body portion 7 of the top tape winding roller 1
A removable and elastic wave-shaped spacer 8 is arranged on the outer side of. On the inner diameter side of the spacer 8, there is provided a protrusion 8a that fits into a slit 7a provided in the winding body portion 7 of the top tape winding roller 1.

As shown in FIG. 1, the tip of the top tape 6 is attached to the spacer 8 of the top tape take-up roller 1 with the adhesive tape 9, and the top tape take-up roller 1 is rotated in the direction of the arrow shown in FIG. It is wound up.

Next, the top tape winding roller 1 of the present invention.
An example of the component supply device 41 will be described with reference to FIG. The top tape take-up roller 1 is attached to the plate 42 of the component supply device 41 via a shaft (not shown) and a bearing (not shown), and the component supply tape 51 is fed by the feed wheel 43 at an equal pitch. The top tape take-up roller 1 rotates in the direction of the arrow in the figure via the lever A44, the link 45, and the lever B46 in synchronization, and the top tape 6 peeled from the top tape peeling portion 47a of the tape pressing guide 47 becomes the guide roller 48. It is guided and wound onto the top tape winding roller 1.

When the top tape 6 is wound up to the top tape take-up limit, the roller A2 constituting the top tape take-up roller 1 is arranged so that the top tape take-up roller 1 can take up the top tape 6 again. Laura B3
Separate from.

The top tape 6 is wound up to the winding limit on the separated roller A2, and the spacer 8 which is a cushioning material between the top tape 6 and the roller A2 is pressed by strongly pressing the outer ring of the top tape 6. Elastically deforms and the top tape 6 is easily removed.

Next, a second embodiment of the present invention will be described with reference to the drawings. The top tape winding roller 11 is a roller A having a flange A14 that guides one side of the top tape 6.
12 and a flange B for guiding the other side of the top tape 6
A pair of rollers B13 provided with 15 are arranged, and a semi-cylindrical and removable air-matt spacer 18 is arranged outside the winding body portion 17 of the top tape winding roller 11. Can be attached to the component supply device 41 having the same configuration as that of the first embodiment. Then, it is fixed to the spacer 18 by the groove adhesive tape 19 of the top tape 6.

In this structure, the collection roller A12 and the roller B13 when the top tape 6 reaches the winding limit.
Then, the spacer 18 between the top tape 6 and the roller A12 is pierced with a needle-shaped rod or the like, so that the winding pressure of the top tape 6 is reduced and the top tape 6 can be pulled out at once.

FIG. 3 shows a third embodiment of the present invention, which has a semi-cylindrical and air mat-shaped spacer 28 provided with an air nipple 28a. Since the other configurations are the same as those of the second embodiment, the description thereof will be omitted. By removing the air that has been injected into the spacer 28, this allows the spacer 28 to be reused while facilitating the removal of the top tape 6 at a time.

FIG. 4 shows a fourth embodiment of the present invention, in which the winding body 3 is provided around the winding body 37 of the roller A32.
A plunger 33 that is movable in the radial direction of 7 is provided.

When this is integrated with the roller B (not shown), a top tape (not shown) is usually wound up, and when the roller A32 is separated from the roller B (not shown). The plunger 33 is retracted into the winding body portion 37 of the roller A32, the winding pressure of the top tape (not shown) is reduced, and the top tape (not shown) is easily removed at a time.

[0019]

As is apparent from the description of the above embodiment, the present invention provides a top tape take-up roller for winding a top tape covering a taping component, and a winding body for the top tape. The top tape is wound up to the winding limit because it has a guide part that guides both sides and the part that has one guide part is separable and a cushioning material is applied to the outside of the winding body part. After returning to the initial state after being damaged, it is possible to compress the cushioning material and pull out the top tape at a time, and it is possible to eliminate unnecessary work time.
