Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a taping component roll in which a taped component is wound around a reel.

[Prior Art] A roll of this type will be described with reference to FIGS. 1 to 3. Electronic components 1, 1 ... Lead wire 2, 2
... are fixed by sandwiching both ends thereof, and the electronic components 1, 1 ... Are fixed at a constant interval so as to straddle these tapes 3, 3.

An isolation sheet 6 is laid under the tapes 3, 3 and the electronic components 1, 1, ... And the ends of the tapes 3, 3 and isolation sheet 6 can be attached to a cylindrical reel core 4. Then, with the separation sheet 6 side facing downward, the tapes 3 and 3 and the separation sheet 6 are continuously wound around the reel core 4 in multiple layers.

[Problems to be solved by the invention]

In this type of taping component roll, a step having a height corresponding to the diameter of the electronic component 1 is formed between the first roll and the second roll, so that there is a gap between the first roll of the second roll and the preceding roll. Therefore, the curvatures of the tapes 3 on both sides are discontinuously different. Therefore, if a shock or the like is applied to the reel 7, it will be 2
The tapes 3, 3 supporting both ends of the lead wire 2 of the electronic component 1 of several pieces from the beginning of the winding are pushed downward so as to follow the tapes 3, 3 of the first winding having a large curvature. The lead wire 2 is bent like the right lead wire 2 shown in FIG.

At the portion where the second to third rolls or the third to fourth rolls are made, the influence of such a step is somewhat mitigated, but the same bending is also caused.

The present invention has been made to solve the above problems in the conventional taping component roll, and an object thereof is to provide a taping component roll in which the lead wire is not easily bent due to the impact of the reel or the like.

[Means for solving problems]

The structure of the present invention will be described with reference to the reference numerals of FIGS. 1 and 2, and the lead wires 12 of the electronic components 11, 11 ...
When multiple windings of the taping component 10 in which both ends of 12 ... Are fixed to the pair of tapes 13 and 13 at a substantially constant interval on the reel core 14 having a cylindrical shape, the taping component 10 on the peripheral surface of the reel core 14 A cushioning sheet 15 having elasticity and having substantially the same thickness as that of the component 11 is attached to a portion before the start of winding. Then, the taping component 10 in the front portion from the first to the second roll is placed on the buffer sheet 15 and wound.

[Action]

With the taping component roll according to the present invention, no step can be formed at the winding start portion of the taping component 10, and a step can be formed at the edge portion of the cushioning sheet 15 in front of it. However, since the cushioning sheet 15 has elasticity, when a force is applied to the tapes 13, 13 and the electronic components 11, 11, ..., For example, as shown in FIG. 2, the electronic components 11, 11 ... It absorbs this external force by sinking inside. This prevents the lead wires 12, 12 ... from being bent due to the step.

〔Example〕

Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The reel 17 is constructed by installing a cylindrical reel core 14 at the center of two disk-shaped side plates 18, 18. Also, electronic parts
11,11 ... are tapes 13 and 13 consisting of two upper and lower adhesive sheets
The tape is taped so that both ends of the lead wires 12, 12 ...

An isolation sheet 16 made of long paper or the like is attached below the taping component 10, and the tapes 13, 13 and the ends of the isolation sheet 16 are attached to the reel core 14, with the isolation sheet 16 side facing down. Then, wind around the reel core 14. In this case, before the first electronic component 11 of the taping component 10,
The buffer sheet 15 is attached in advance, and the taping component 10 in the front portion before the second roll is placed and wound on this.

The width of the cushioning sheet 15 is the same as or slightly wider than the width of the taping component 10. Also, the length is
It is recommended that the number of taped electronic components 11, 11, ...

The material of the buffer sheet 15 is preferably light and highly elastic. For example, a foamed resin sheet such as polyurethane foam may be attached to the peripheral surface of the reel core 14 with an adhesive material or a double-sided adhesive sheet.

In addition, the taping component roll according to the present invention was actually made by using the cushioning sheet 15 made of foamed polyurethane, and the impact test was performed on the roll.
No bend was recognized. On the other hand, in the conventional taping component roll, in a similar impact test, the lead wires of the five electronic components 11, 11, ... Are recognized to have a certain degree of bending.

[Effect of device]

As described above, according to the present invention, the step from the first roll of the taped electronic components 11, 11 ... to the second roll is substantially up to the edge of the buffer sheet 15 in front of it. Since the buffer sheet 15 absorbs the force applied to the lead wires 12, 12 ... At the same step, the lead wires 12, 12 ... Do not bend due to the step.
