JPH04160710A - Method of correcting warp of lead wire - Google Patents

Abstract

PURPOSE:To correct a warp, which is generated by winding of a lead wire around one of outlet side contact reels, and the residual warp of a last stage mutually by turning a base plate for adjustment at narrow width around of a contact point within the surface. CONSTITUTION:Multiple reels 2 are located into two lines alternatively on a reel base plate 1, and outlet side reels (a), (b) are made to contact to the reel line at right angle and this contact point is showed with (p), and a lead wire 3 is pinched at the point (p) freely to pass through, and the while base plate 1 can be turned normally and reversely around of the point (p). An angle of turn of the base plate 1 is adjusted by a turn adjusting hole 4 provided in the inlet side of the base plate 1 and an adjusting screw 5 engaged with this adjusting hole. About arrangement of the reels 2, bite of the reels 2 is made large at the inlet side, and bite is reduced gradually as the reels 2 come close to the outlet to reduce a quantity of warp repeated by the lead wire passing through the reel line. The warp generated by winding of the lead wire around the reels 2 and the residual warp of a last stage are thereby corrected mutually to facilitate the adjustment.

Description

DETAILED DESCRIPTION OF THE INVENTION (Objective) The object of the present invention is to pass the lead wire unwound from one reel through reels arranged alternately to remove curls.

Conventionally, straightening the winding line required delicate adjustments based on experience, and adjustments were made such as increasing the number of rollers arranged alternately and reducing the rate of decrease in the winding angle, but these took up space. There were disadvantages such as increased cost.

(Structure) Next, the present invention will be explained in detail based on the drawings. FIG. 1 shows the basic form of the present invention. Reel board (1
), a plurality of reels (2) are arranged in two different rows, and reels a and b on the exit side are brought into contact with the reel row at a right angle, with the contact point being P, and the lead wire (3 ) is sandwiched so that it can pass freely, and the board (], ) is centered at two points.
is configured so that it can perform reciprocating rotation. The rotation angle of the board (1) is the same as the winding angle of the lead wire of reel a or reel b, and this rotation angle is the rotation angle provided on the inlet side of the board! g
li! Hole (4) and adjustment screw (5) fitted into the adjustment hole
adjusted by. The arrangement of the reels (2) increases the bite on the inlet side, and decreases the bite as it approaches the exit to gradually reduce the amount of repeated warping of the lead wire passing through the reel row. Figure 2 shows an application of the present invention. By assembling two substrates at right angles, the lead wires are straightened by correcting warpage in the vertical and horizontal directions.

(Effect) Reels a and b sandwiching the lead wire at point p
Each wrapping angle of a increases with the small reciprocating rotation of the board.

b Compensating for the warpage caused by winding on one of the reels and the residual warpage in the previous stage, and detecting the warpage at the exit to cope with changes in warpage due to variations in lead wire material and winding diameter. This can be achieved by automating the rotation adjustment.

Claims (1)

[Claims] In a warp correction method in which reels are arranged in two alternating rows on a board and lead wires are made to meander, a set of two reels are brought into contact with the rows at right angles to the exit, and the board is moved in-plane with the contact point as the center. A lead wire warp correction method that corrects and straightens the warp caused by winding around one side of the exit side contact reel and the residual warp in the previous stage by adjusting the lead wire by small rotation.
