Abstract

(57) [Abstract] [Purpose] To provide a reel for a carrier tape, which can be lightened or can be freely changed in strength, can be easily manufactured in composition, and has good workability. [Structure] A side plate 1 provided with a radius 7 on an inner surface of an outer peripheral edge has a shaft end 3 with which a half is formed. The half halves A and A of the same type, which are opposed to each other, are made of a foamable synthetic resin material. Then, the half-divided bodies A, A are joined at the engaging end surface 4 by fitting the concave and convex portions 5, 6. [Effect] The weight can be reduced or the strength can be freely changed, and heat resistance, conductivity, oil resistance, etc. can be freely supported. Further, the composition is easy and the workability can be improved. Furthermore, since the inner surfaces of the outer peripheral edges of both side plates are rounded, it is very easy to wind the tape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reel for carrier tape which can be lightened or can be freely changed in strength, and whose composition can be easily manufactured.

[0002]

[Prior art]

 Conventionally, as a take-up reel of a tape for packaging components, which is configured to continuously store and package components such as IC and LSI at regular intervals, for example, a half plate of the same type having a side plate, a projecting surface, an axial hole, etc. Parts made by vacuum-molding a body with a thin plastic sheet, and joining the halves by means of projections and depressions that can be fitted to each other on the projecting surface. No. 85557) is known.

[0003]

[Problems to be solved by the device]

 However, since the above conventional reel is made of a thin plastic sheet, it has problems in terms of strength and deformation and deflection despite its weight, and the joining of the half halves is due to the concavo-convex fitting of each other. Workability in composition production was poor.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and is configured as follows.

That is, in the reel for carrier tape of the present invention, side surfaces having rounded inner surfaces of the outer peripheral edge are provided with concavo-convex portions of taper outer circumferences which can be fitted to each other on the engaging end surface of the half winding core having an integral shaft hole. It is characterized in that the half halves of the same type, which are opposed to each other, are made of a foamable synthetic resin material, and the half halves are joined at the engaging end faces by fitting concave and convex portions. Next, the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[0006]

[First Embodiment] First, in A and A, side plates 1 having rounded edges 7 on the inner surface have a shaft hole 3 integrated with one another. Interlocking end faces 4 of a half winding core 2 can be fitted with tapered outer peripheries 5a and 6a respectively. The same halves are formed by pairing different concave-convex portions 5 and 6, and the halves A and A are made of, for example, a foamable synthetic resin material which is a bead-molded product of foamed polystyrene. The concave portions 5 and the convex portions 6 have a truncated pyramid shape with tapered outer circumferences 5a and 6a so as to facilitate mutual fitting. The halves A, A are joined at the engaging end faces 4, 4 by fitting and bonding the uneven portions 5, 6. In FIG. 4, 8 is an adhesive.

[0007]

[Effect of device]

 As described above, in the carrier tape reel of the present invention, since the half body is composed of the expandable synthetic resin material, which is a foamed bead molded product, it is possible to expand the foamed beads by using the foamed beads in the same mold. By changing the magnification, the weight can be reduced or the strength can be freely changed, and by changing the characteristics of the raw material of the expanded beads, it is possible to freely cope with heat resistance, electrical conductivity, oil resistance, etc. Further, since the outer circumferences of the mutually fitting concavo-convex portions which are opposed to each other in the same type of half body are tapered outer circumferences, the composition is easy and the workability can be improved. Furthermore, since the inner surfaces of the outer edges of both side plates are rounded, there is an advantage that it is very easy to wind the tape.
