Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a member for fixing a side plate of a reel for winding a film or tape to a predetermined width, and particularly for storing and transporting and storing various small electronic parts, etc. Regarding members.

[0002]

[Prior art]

 Conventionally, carrier tapes are generally transported and stored in an outer case in which a carrier tape containing electronic components is wound on a reel made of paper or synthetic resin.

[0003]

[Problems to be solved by the device]

 The conventional paper or synthetic resin reels described above tend to warp or break inside or outside the reel side plates due to changes in temperature and humidity, which makes it difficult to pull the carrier tape from the reel smoothly. Furthermore, there was a problem of causing deformation of the carrier tape. In addition, the side plate of the reel is pushed inward by external pressure generated during transportation and the width of the reel is narrowed, which causes the same problem as described above.

The present invention solves the above-mentioned problems of the related art, prevents the carrier tape from being deformed, and prevents the reel side plate from warping because the reel can be pulled out constantly and smoothly. It is an object of the present invention to provide a reel side plate fixing member capable of holding a predetermined width of the reel side plate.

[0005]

[Means for Solving the Problems]

 The reel side plate fixing member of the present invention has a structure in which a pair of holding portions having a U-shaped cross section are integrally formed in the same direction at both ends of a back plate having a predetermined width.

The sandwiching section is formed in a U-shape in cross section by the overhanging plate sections facing each other. The width of the opening between the facing plate portions of the sandwiching portion is formed to be slightly wider than the thickness of the reel side plate so that the reel side plate to be applied can be easily received. Further, a protrusion is formed on the inner side surface of the overhanging plate portion, and the reel side plate pushed from the opening is sandwiched between the overhanging plate portions by this protrusion.

The protrusion is integrally formed on one or both of the inner side surfaces of the facing plate portion facing each other. The projection may have any curved shape as long as it can hold the side plate of the reel with the holding section. For example, a plurality of partially spherical projections may be formed at intervals. Alternatively, it may be formed as a ridge having a semi-cylindrical shape. It is advisable to form such protrusions such that the closest distance between the protruding plate portion and the overhang plate portion facing each other is slightly smaller than the thickness of the reel side plate.

Further, the overhanging length of the overhanging plate from the back plate should be formed so that the reel side plate inserted into the holding part does not easily come off the holding part, and it depends on the size and thickness of the reel. Although it is different, it is usually formed to be 5 mm to 10 mm. If the thickness is 5 mm or less, the fixing member easily comes off from the reel side plate, and if it is 10 mm or more, the storage space for the carrier tape is reduced, which is inconvenient.

Further, the opposing left and right overhanging plates may be extended to the same length, but if either the left and right overhanging plates are extended, it is practical because the fixing member can be easily inserted into the reel side plate. . Further, the back plate is preferably formed in an arcuate curved plate corresponding to the outer periphery of the side plate of the reel, and further, the back plate needs to have a rigidity that maintains a predetermined width substantially equal to the reel width.

The reel side plate fixing member of the present invention is not particularly limited as long as it is a material having rigidity that maintains a predetermined width, but a thermoplastic resin is advantageously used. Examples of such a material include vinyl chloride resin, polystyrene, polycarbonate, ABS, and acrylic resin. A particularly preferred material is polystyrene. Further, the fixing member of the present invention can be manufactured by injection molding or compression molding of these materials using a predetermined mold.

The reel side plate fixing member of the present invention can be easily attached to the reel by applying the pinching portions of the fixing members to the outer peripheral edges of the reel side plates facing each other and pushing the back plate toward the reel side. You can Further, the reel side plate fixing member of the present invention is usually used by being attached to the outer peripheral edge of the side plate of the reel at 2 to 4 places at equal intervals.

Hereinafter, the reel side plate fixing member of the present invention will be described with reference to the drawings. FIG. 1A is a front view for explaining a state in which a reel side plate fixing member according to an example of the present invention is attached to a reel side plate, and FIG. 1B is a side view thereof. 2 and 3 (a) are front views for explaining a state in which a reel side plate fixing member of another example of the present invention is attached to the reel side plate, and FIGS. 2 (b) and 3 (b) show the same. It is each side view.

In the reel side plate fixing member 1 of the present invention shown in FIG. 1, holding portions 3 and 3 having a U-shaped cross section for receiving the outer peripheral edge of the reel side plate 2 are integrally formed at both ends of the back plate 4. The opposing overhanging plate portions 5 and 6 that are formed to form the sandwiching portion 3 having a U-shaped cross section have a long outer side plate portion 6, and a half for holding the reel side plate 2 in the center of the inner side surface thereof. The protrusions 7 having a spherical shape are integrally formed at two places with a gap.

In the reel side plate fixing member 1 shown in FIG. 2, the inner side plate portion 5 of the opposed overhanging plate portions 5 and 6 forming the holding portions 3 and 3 is formed long, and the reel is provided at the center of the inner side surface thereof. The projecting portion 8 of the chamfered ridge that holds the side plate 2 is integrally formed.

In the reel side plate fixing member 1 shown in FIG. 3, the inner side plate portion 5 and the outer side plate portion 6 of the opposed projecting plate portions 5 and 6 forming the holding portions 3 and 3 are formed to have the same length, and the outer side plate Semicircular spherical projections 9 for sandwiching the reel side plate 2 are integrally formed at three locations at the end edge of the section 6 with a space therebetween.

[0016]
