[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for winding a carrier tape for carrying electronic parts (hereinafter referred to as a carrier tape).

[0002]

2. Description of the Related Art Conventionally, a carrier tape has been wound around a reel in a single row. Therefore, the outer shape of the reel has been enlarged to meet the demand for long winding.

[0003]

When reels are wound up in a long length in a single row, there is a drawback in that the outer shape of the reel becomes too large, which makes handling and transportation difficult.

[0004]

According to the present invention, the above problems are solved. That is, according to the present invention, a carrier tape having an embossed portion molded from a thermoplastic synthetic resin sheet has a constant core tension of 100 to 800 g and a core diameter of 200.
The reel is made of foamed resin and has a width of 1 mm or more and less than 300 mm.
A gist of a carrier tape winding device for electronic component transportation is characterized in that the carrier tape is traversed when it is swung in a direction and reaches one side plate of a reel.

The device of the present invention will be described below with reference to the drawings. As shown in FIG. 4, the carrier tape 1 handled by the device of the present invention is provided with an embossed portion 1b for storage which is continuous with the flange portion surface 1a.

The winding device of the present invention has the structure shown in FIG. 1, and the carrier tape 1 molded by a molding machine (not shown) has a drive roll 2a, a step roll 3, a drive roll 2b, and a cutting mechanism 4. After that, it is taken up by the take-up reel 5. In this apparatus, as shown in FIGS. 1, 2, and 3, the tension applied to the carrier tape 1 is freely adjusted by setting the weight 6, and the winding roll 7 is passed through the step roll 3.
The carrier tape 1 is fixed to one end of the reel 5 set to, and the carrier tape 1 is wound while the reel 5 touches the left and right.

FIG. 2 shows the structure of the step roll 3.
In order to keep the tension applied to the carrier tape 1 constant, the weight 6
The fluctuation of the chain 8 connecting the step roll 3 and the step roll 3 is detected by the potentiometer 9, and when the fluctuation is large, the winding speed is slowed down, and when the fluctuation is small, the winding speed is increased. The taking speed is controlled so that the weight 6 and the step roll 3 are always balanced and stable. The reel 5 used here has a medium core diameter.
Is preferably 200 mm or more and less than 300 mm
Good If it is less than 200 mm, the carrier tape 1 has a winding tendency.
It is easy to wear, and if it is 300 mm or more, it is larger than the outer diameter of the side plate.
It becomes difficult to wind it around the carrier tape 1. Lee
The side plate of the le has an outer diameter of 300 to 700 mm and a winding width of 100 to 3
It is preferable to use a foamed resin with a light weight of 00 mm and good dimensional accuracy.
Good

Further, the carrier tape 1 is 100-800.
In order to prevent the embossed portion 1b from fitting into the embossed portion 1b of the already wound carrier tape 1 while keeping it at a constant tension within the range of g, the flange portion 1a of the carrier tape 1 is rolled up within 1 mm and wound up. It is required to go. As a result, the embossed portion 1b of the carrier tape 1 is not deformed and is stably wound to the end. Further, since the tension is constant until the end, the carrier tape 1 is prevented from collapsing in the outer peripheral portion of the reel. Re winding collapse occurs when less than 100 g, 80
If it exceeds 0 g, the embossed part will be crushed.

FIG. 3 is a cross-sectional view of the winding portion. A cam groove 10 corresponding to the swing width of the carrier tape 1 is cut in a scroll cam shape on the winding shaft 7, and the winding motor 11 has a winding groove. In synchronization with the rotation, the winding shaft is guided by the claw 12 and moves in accordance with the cam groove 10, so that the winding tape is shaken in one direction at a constant width, and the predetermined position, that is, the carrier tape 1 is placed on one side plate 13 of the reel 5. When it comes, it repeats the action of being swung in the opposite direction by a constant width. Winding shaft 7
Since the reel 5 fixed to the same operates as the winding shaft, the carrier tape 1 is stably traversed.

[0010]

[Example] Reel core diameter 220 mm, winding width 150 m
m, using expanded polystyrene resin reel outer diameter 570mm of the side plate, it was possible to wind the 48000 amino embossments 12mm wide, the carrier tape embossed depth 5.7mm in traverse winding.

[0011]

According to the present invention, since the carrier tape can be stably wound around the reel in a traverse manner, long length winding is possible, the number of times of reel replacement during manufacturing and taping is reduced, and labor is saved. Furthermore, the reel (packaging) cost and the logistics cost of the carrier tape can be reduced.
