[Industrial applications]

 INDUSTRIAL APPLICABILITY In the electronic component processing industry, the present invention is an electronic component used for winding, storing, and transferring between manufacturing processes of electronic components such as metal band plate forming products, resistors, capacitors, etc., which are used as electronic components, and transportation between processes. The present invention relates to a winding reel.

[0002]

[Prior art]

 In the electronic parts industry, many electronic parts such as connectors and terminals are molded from various metal strips.The above electronic parts are produced by using a molding machine in which a feeding device and a winding device are arranged before and after a press machine. It is continuously press-formed from various long metal strips. In addition, electronic parts such as resistors and capacitors are also in continuous production.

The metal strip plate processed and formed by the press machine as described above is wound on a reel on the winding device side and used for storage or transportation. In addition, reels were used between processes and during transportation for continuous production of electronic parts such as resistors and capacitors. The conventional reel used in the electronic component industry is constructed by integrally assembling two flat side discs and an inner ring for a cylinder body that is concentrically arranged between the side discs. Was there.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional reel, since the side disk and the inner ring for the case cylinder are integrally fixed, it is necessary to prepare a reel having an inner ring according to each product width. However, there is a problem in that it is expensive to manufacture and store the reels. Also, due to long-term use and winding of heavy objects, the side discs will be deformed and smooth winding will not be possible, and the reel must be discarded or the reel parts must be replaced. However, there is a problem that the work becomes complicated and the cost becomes high.

The present invention has been made in order to solve the problems of the above-mentioned conventional techniques, and its purpose is to allow the reel width to be adjusted. It is possible to handle products of various widths with different types of reels, and by finely adjusting the reel winding width, it is easy to correct variations in winding width due to deformation of the side disc. It aims to provide a reel for winding electronic components that can be carried out.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the reel for winding electronic parts according to the present invention divides an inner ring for a roll cylinder disposed between side discs into two parts, and one of the outer periphery of the inner ring disposed on one side disc. A male screw is processed by leaving the winding part on the side disc side on the part, and a female screw that is screwed with the male screw is processed on a part of the inner circumference of the inner ring arranged on the other side disc. By screwing the male and female screws together, the distance between the two side disks can be adjusted, and both side disks are arranged in parallel. In addition, the spacer is fixed to the inner side of the inner ring provided on one side disc in the radial direction, and the other side disc is fixed to the spacer with an adjusting screw, so that the two side discs are fixed. Then, a reel for winding up electronic components with a constant winding width is constructed.

[0007]

[Action]

 By using the reel for winding up electronic components having the above-mentioned structure, the winding width of the reel can be freely expanded or reduced by removing the adjusting screw and rotating the two side plates with respect to each other. Further, after determining the reel width, the two side disks are fixed by adjusting screws to obtain a reel whose reel width does not change during use.

[0008]

【Example】

 An embodiment of an electronic component winding reel according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1, 2 and 3, the electronic component take-up reel 1 has two side discs 2 and 3 and one of the two side discs 2 and 3. It is composed of inner rings 4 and 5 which are individually arranged, and a spacer 6 which is arranged on either one of the two side circular plates 2 and 3.

A male screw 8 is machined on a part of the outer periphery of the inner ring 4 on the side of the side disc 2 except for the winding portion 7, and is fixed to the side disc 2 by a fixing screw 9.

The inner ring 5 is formed with a female screw 10 which is screwed onto the male screw 8 on a part of the inner periphery thereof, and a winding portion 11 on the outer peripheral surface of the side disc 3 is wound on the inner ring 4. It is fixed by a fixing screw 9 so as to be flush with the catch 7.

Further, the spacer 6 is composed of a substantially cylindrical body having a female screw 12 penetrating substantially in the center thereof, and is formed on the side circular plate 3 inward of the inner ring 5 provided on the side circular plate 3 in the radial direction. It is fixed with a fixing screw 9.

Reference numeral 13 in the drawing denotes a bearing having a bearing hole 14 in the center, which is fixed to the side disc 2 and the side disc 3 by fixing screws 9, respectively. The bearing 13 is formed in two, and is configured to have the smallest reel width in a state of being in contact with each other, but it is also possible to have an integral structure and fix it to one of the side discs. Further, the bearing 13 can be omitted by directly forming bearing holes in the side discs 2 and 3.

After the inner ring 4 and the inner ring 5 provided on the side disc 2 and the side disc 3 configured as described above are screwed to each other and the reel width is set to a predetermined value, the adjusting screw 15 is attached to the spacer 6 It is fixed by being screwed onto.

When the inner race 4 and the inner race 5 are screwed together as described above, the winding section 7 and the winding section 11 form a winding cylinder.

In the above embodiment, the pitch of the screws formed on the inner races 4 and 5 is 4 mm, and the winding width is expanded by 1 mm each time the side disc 3 rotates 90 degrees with respect to the side disc 2. In addition, the winding width is minimized when the male screw 8 and the female screw 10 are completely screwed, and the winding width is enlarged when the screw is loosened. By arbitrarily setting the pitch of the screw, it is possible to set the winding width distance for the rotation of the screw.

The side circular plates 2 and 3 are formed of aluminum alloy circular plates having a plate thickness of 3 to 5 mm, and a plurality of window holes 16 and a plurality of driving holes 17 can be provided if necessary. The inner rings 4 and 5 were formed by cutting an aluminum alloy extruded circular pipe into a predetermined width and then machining the male and female threads 8 and 10, respectively.

Although the side discs and the inner ring are formed by using an aluminum alloy as described above, a metal such as a steel plate or a steel pipe, or a thermoplastic resin typified by polypropylene, a fiber reinforced thermoplastic resin, or an unsaturated metal is used. It may be formed using a thermosetting resin typified by polyester or FRP in which the resin is reinforced with fibers, or further, cardboard, a plywood board or the like. The spacer can also be formed using the same material as above.

Further, although the bearing is machined from a steel pipe and is galvanized, an aluminum alloy can also be used.

【The invention's effect】

 Since the present invention is configured as described above, the winding width of the reel can be adjusted according to the width of the product, and it is not necessary to prepare a reel for each product having a different width as in the conventional case, and one reel can be used. It can be used for products of various widths. Therefore, the number of reels held can be significantly reduced, and the cost of manufacturing and storing the reels can be significantly reduced. Further, since the winding width can be finely adjusted, the product can be wound up smoothly and has practical effects that are economical and excellent in productivity.
