Abstract

PURPOSE:To prevent generation of a step, and to wind a taping component concentrically at different curvature smoothly at a winding core by forming a recess for mounting an embossed part of the component from the midway of a groove formed on the core toward the peripheral side of the core. CONSTITUTION:When the starting end 20 of a taping component 2 is inserted into the groove 40 of a winding core 4 and a reel for the component is rotated, the component 2 is operated with tension upon rotating and intruded. The emboss 22 continued to the starting end 20 of the component 2 is mounted at the recess 46 of the core 4, and formed to the periphery of the core 4 along the curved surface 46 of the recess 46 and an oblique surface 464. As a result, the component 2 is wound in an ideally winding state on the core 4. That is, since the emboss 22 is introduced into the recess 46, a step D due to the emboss 22 like in prior art is suppressed, and a naturally and ideally winding state in which radius of curvature is gradually increased upon winding is obtained.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a reel for taping parts, which is used for storing, transporting, etc. the taping parts by winding them around the reel.

[Conventional technology]

Conventionally, as shown in FIG. 4, for example, a reel for taping parts has a winding core part 4 formed in the center thereof around which the taping part 2 is wound, and a winding core part 4 on both sides of the winding core part 4. Flanges 61, 62 are attached for holding the side parts of the spirally wound taping part 2. As shown in FIG. 5, the winding core 4 has a groove 4 for hooking the starting end 20 of the taping component 2.
0 is formed, and the starting end 20 of the taping component 2 to be wound around the rotating taping component reel.
It is to bring them together and involve them.

[Problem to be solved by the invention]

By the way, in the taping component 2, embossments 22 are formed at regular intervals on a tape 21 made of synthetic resin by molding, and the component 10 is stored in a storage section 23 formed inside the embossment 22. 23 is tape 2
1 is closed by tape 24 attached to it. Such a taping part 2 can be freely curved because the tape 21.24 is flexible and the area between the embossments 22 is a flat part of the tape 21.24. , it can be spirally wound around the winding core 4 of the reel for taping parts. However, when such a taping component 2 is wound around the winding core 4, the embossing 22 on the starting end 20 side is continuously wound around the circumferential surface of the winding core 4, and the fifth
As shown in the figure, a step is created depending on the height of the embossing 22. This step causes the radius of curvature from the center of the winding core 4 to be partially biased due to the overlapping of the taping parts 2 to be wound, resulting in an irregular spiral. The amount of winding of the taping component 2 on the taping component reel is proportional to the size of the flanges 61 and 62, but if the winding state of the taping component 2 becomes distorted, the winding amount of the taping component 2 on the reel for taping components is proportional to the size of the flange 61, 62, but if the winding state of the taping component 2 becomes distorted, the winding amount of the taping component 2 is Since the taping component 2 is exposed from the edges of the flanges 61 and 62 at the stepped portion, it becomes difficult to wind the taping component 2, and the efficiency of storing the component 10 decreases. For example, 30cm
Since the length of the taping part 2 wound around the outer periphery of the flanges 61 and 62 is approximately 90 cm, if the number of embossing parts 22 in that 90 cm section is about 100, one taping part reel will have 100 embossing parts. The number of items stored will decrease. If the diameter of the flanges 61 and 62 were increased by that amount in order to secure the storage capacity, the taping parts reel would become larger, which would affect the box and installation area for storing the taping parts reel. This is inconvenient because it also becomes Moreover, the fact that the wound state of the wound taping component 2 is distorted also reduces the quality of the product. When unwinding the taping component 2 wound on such a step from the taping component reel, the unwinding torque will be different with respect to the center.
There are inconveniences such as the unwinding speed changing and parts supply becoming unstable. Therefore, this invention prevents the occurrence of such a step,
The purpose of the present invention is to provide a reel for taping parts that allows the taping parts to be wound concentrically around a winding core part with gently varying curvatures.

[Means to solve the problem]

That is, in the reel for taping parts of the present invention, flanges (61, 62) for holding the taping part wound around the core part are attached to both sides of the core part (4) around which the taping part (2) is wound. In the reel for taping parts, a groove part (40) is formed in the core part to hook the starting end part (20) of the taping part, and the groove part (40) for hooking the starting end part (20) of the taping part is formed in the core part. A recess (
46, 46A, 46B).

[For production]

According to the reel for taping parts of the present invention, when the starting end of the taping part is hooked into the groove formed in the core, the embossment connected to the starting end extends from the middle of the groove to the circumferential surface of the core. It is installed in a recess formed in the area leading to the base. As a result, the concave portion is compensated for by the embossing, and the winding core takes on a circular shape due to the embossing, so the taping part forms an ideal spiral shape without creating a step D (Fig. 5). It is wrapped around the top of the body.

【Example】

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. FIG. 1 shows an embodiment of a reel for taping parts according to the present invention. The winding core 4 on which the taping component 2 is to be wound is formed into a disk shape from a foamable synthetic resin such as expanded polystyrene, and on both sides of the winding core 4 there are circular holes for holding the wound taping component 2. flanges 61 and 62 are fixed concentrically. A support hole 42 for attachment to a support shaft is formed in the center of the winding core 4 and flanges 61, 62. 44 is a kerf. A taping part 2 to be wound is attached to the winding core 4.
A groove 40 for hooking the starting end 20 of the tape 21, 24 is formed, and as shown in FIG. A recess 46 into which the embossing 22 is inserted is formed. These four parts 46 prevent the protrusion of the embossing 22 connected to the starting end 20 of the taping component 2 and gently direct the taping component 2 toward the circumferential surface of the winding core 4.
It is deep enough to install the side embossing 22 inside,
The shape gradually approaches the circumferential surface of the winding core 4. This recess 4
The cross-sectional shape of No. 6 is, for example, a curved surface 462 with a small radius of curvature on the inner wall portion of the groove portion 40, and a portion extending from this curved surface 462 to the circumferential surface of the winding core portion 4 is set as a gently sloped surface 464. Note that the curved surface 462 may be a tapered surface, and the inclined surface 464 may be a gently curved surface continuous to the curved surface 462. With this configuration, when the starting end 20 of the taping component 2 is inserted into the groove 40 of the winding core 4 and the taping component reel is rotated, the taping component 2
is pulled in by tension. The embossment 22 continuous to the starting end 20 of the taping component 2 is located in the recess 46 of the winding core 4.
That is, it extends along the curved surface 462 and inclined surface 464 of the recess 46 to the peripheral surface of the winding core 4 . As a result, the taping component 2 is wound onto the core 4 in an ideal spiral state. In the taping component 2 wound around the core 4 having the recess 46, the emboss 22 enters into the recess 46, so the occurrence of a level difference due to the emboss 22 as in the conventional case is suppressed, and as the taping part 2 is wound up, A natural and ideal spiral state is created in which the radius of curvature gradually increases. Therefore, the ideal winding amount determined by the diameters of the flanges 61 and 62 can be wound on the winding core 4, and in addition to increasing the winding amount, the recess 46 is also slightly embossed 22. Since the taping parts 2 are installed, the number of taping parts 2 wound around one taping parts reel increases, and the storage efficiency of parts 10 is improved. In other words, if the amount of winding is the same as before,
Since the diameters of the flanges 61 and 62 can be made smaller, the reel for taping parts can also be made smaller. Since the wound taping part 2 has a natural spiral shape without partially protruding, the quality of the product can be improved. Next, FIG. 3 shows another embodiment of the reel for taping parts of the present invention. In the embodiment described above, the recess 46 was formed on one wall side of the groove 40, but in this embodiment, recesses 46A and 46B are formed at the front and rear sides of the groove 40. Each of the recesses 46A, 46B is formed with a curved surface 462 and an inclined surface 464 as in the previous embodiment. In this way, the starting end 2 is placed in either the recess 46A or the recess 46B in accordance with the winding direction of the taping component 2.
Since the emboss 22 on the 0 side can be placed, the occurrence of a step D (FIG. 5) due to the emboss 22 can be suppressed, and the taping component 2 is wound onto the winding core 4 in an ideal spiral state. In addition, in the example, the case where the emboss is placed on the winding core side is explained, but it can also be applied to the case where the emboss is placed on the outside and the emboss is stored in the recess. This will allow you to create an ideal spiral shape.

【Effect of the invention】

As explained above, according to the present invention, since the recessed portion in which the embossed part of the taping component is installed is formed from the midway part of the groove formed in the winding core toward the circumferential surface of the winding core, the winding The emboss of the first taping part is placed in the recess, and the taping part wound on the winding core is wound in an ideal spiral shape without creating a step, which improves the winding efficiency. Furthermore, it is possible to prevent changes in the rewinding speed and stabilize the supply of parts.
