Abstract

PURPOSE:To prevent any stress from occurring in a sheet, by installing a driving roll, coming into contact with one side of the sheet, and a sheet guide device, coming into contact with the other side of the sheet, in the upper part of the roll, while interposing each clearance in the said guide device and in a contact part between the roll and the sheet, and forming a curved shifting part of the said sheet there. CONSTITUTION:A sheet 4 is released out of a sheet coil 4' of an uncoiler 1, making the backside contact (6') with a sheet guide device 6, and when a surface of the said sheet 4 and the surface of the sheet 4 is made contact (5') with a driving roll 5 at the lower part, a clearance (t) is interposed between both these contact parts 5' and 6' so that the said sheet 4 is curved in a almost S-shaped form. Therefore, when the driving roll 5 is rotated, the sheet 4 is able to go down to a loop 8 without being slipped at these contact parts 5' and 6; between the said roll 5 and the guide device 6, and further it is subjected to a slitter 3. At a curved shifting part, adapting to rotation of the driving roll 5, the sheet 4 is shifted to the lower part by contact resistance between the sheet 4 and these contact parts 5' and 6' so that no tractive force is subjected to the said sheet 4, and there is no doubt that the uncoiler 1 is being controlled for its speed.

い欠陥があった。``Prior art'' When returning the thin plate for IO lead frames wound on the uncoiler to the slitter line, the unwound thin plate is conventionally held and pulled by pinch rolls P as shown in FIG. A speed detector (PQ) measures the speed of the thin thin plate being wound up.
etc.), the circumferential speed of the pinch roll P is controlled [
1! It was something to do. Therefore, tension is applied to the thin plate for the IO lead frame wound around the uncoiler, and the tension is latent in the thin plate as internal stress. Therefore, when the thin plate is sheared into small NM plates by the slitter in the next process, the release of the internal stress causes edge deformation and warping of the thin plate. When an attempt was made to separate the thin plate from the thin plate coil being wound by moving the thin plate by controlling the speed, there was a defect in that the thin plate remained tightly wound around the coil in a vacuum state, making it difficult to unravel.

Since #1t is bent, the same 4-piece board is curved almost in an S shape. Therefore, when the driving roll 5 is rotated, the four thin sheets can be lowered into the same roll 5 and into the thin sheet hanging portion (loop) 8 without the above-mentioned plan, and are further applied to the slitter 3.

8.8 is provided. The uncoiler 13t coiler 2 is rotated in accordance with the circumferential speed of the thin plate filler 4.4 which is being wound up, and its rotation is controlled by a voltage speed control device. The speed is detected by a speed detection device 9 (pulse generator or PG) in contact with the thin plate 4 wound around the coil 4, and voltage speed control of the uncoiler 1, the recoiler 2, and the slitter 3 is performed based on the detection signal. An Fi thin plate coil 4 is wound around an uncoiler 1, the thin plate 4 is uncoiled, and the coil 4 is unwound in the direction of arrow a. 5.6.

成して本差支えない。As shown in FIG. 1, the surface contact portion 5.6 forms a curved transition portion 7 of the thin plate 4 with a space t interposed therebetween. The speed of the drive roll 5 is also controlled by the signal from the PG9, and the circumferential speed of the winding thin plate fill 4 of the uncoiler 1], OO
m/lJ+ is set to about 7101 m/min. The four-piece hanging part 8 of the thin plate that has passed through the curved transition part 7 is hung on the slitter 3, and is sheared into a plurality of narrow thin plates 4 by the slitter 3, transported in the direction of the arrow, and guided by the curved transition part 7 as described above. Therefore, no traction force or pressing force is applied to the thin plates 4 before and after the slitter 3.
