Description

  The present invention relates to a side trimmer device that cuts and removes both edges along the longitudinal direction of a stripper or the like that divides a strip material such as a rolled steel plate into multiple predetermined widths while transferring the strip material. .

  When a strip material such as a rolled steel plate is divided into multiple strips in the width direction, a pair of arbors with disc-shaped slitter blades attached at a predetermined interval are arranged in parallel vertically across the pass line of the strip material. The slitter which cuts the strip plate material to be cut with the upper and lower slitter blades is used. In this slitter, trimming is performed in order to cut and remove defective portions at both ends. In the strip trimmer device, disc-shaped slitter blades are arranged vertically opposite to each other with a pass line of the strip plate interposed therebetween. As shown in FIGS. 6 and 7, the arbors 51 and 52 include arbor shafts 53 and 54, disc-shaped slitter blades 55 and 56 fitted around the arbor shafts 53 and 54, and the slitter blades 55, Annular spacers 57 and 58 that hold 56 at predetermined intervals, elastic rings 59 and 60 that surround the peripheral surfaces of the annular spacers 57 and 58, and a fixing member 61 that presses and fixes these elements. .

  The axial positions of the upper and lower slitter blades 55 and 56 are adjusted by increasing or decreasing the number of annular spacers 57 and 58 of the arbor shafts 53 and 54 in accordance with a set value such as the plate width of the strip plate material S. . In addition, the distance between the axes of the arbor shafts 53 and 54 is adjusted such that the circumferential surfaces of the pair of slitter blades 55 and 56 are horizontal surfaces having substantially the same height. The speeds of the arbors 51 and 52 are controlled so as to synchronize with the passing speed of the band plate material S by rotation driving devices (not shown) connected to the arbor shafts 53 and 54, respectively.

  Here, as shown in FIG. 8, in the conventional side trimmer device, a holder ring 64 is fitted to the arbor shaft 54 in the vicinity of the lower slitter blade 56. The holder ring 64 is a laminated layer composed of an annular outer layer member 65 and an inner layer member 67, and an elastic layer 66 in which an elastic body made of urethane rubber or the like is fitted between the outer layer member 65 and the inner layer member 67. In the state where the band plate material S does not pass through the body, it forms a horizontal surface having the same height as the lower slitter blade 56, but when the band plate material S is introduced, the edge SE of the band plate material S is: It is sandwiched between the slitter blades 55 and 56 at the end, and is pushed down by the upper slitter blade 55 and cut. At this time, the pressing force of the upper slitter blade 55 is applied to the outer layer member 65, the elastic layer 66 is compressed and deformed, and the thickness of the cutting waste 62 is slightly flattened by the pressing action of the upper slitter blade 55 and the holder ring 64. To do. Accordingly, the trim margin can be greatly reduced, and deformations such as twisting and warping of the cutting waste 62 are reduced and relaxed, and the quality of the product strip material S is stabilized.

The strip-shaped cutting waste 62 generated in this way is guided by a guide member (not shown) and wound around a scrap winder 63 as shown in FIG. Conventionally, when the slitter operation is started, the operator grasps the cutting waste 62 by hand and winds it on the scrap winder 63, and then the scrap winder 63 is driven to rotate in synchronization with the speed of the strip material S to wind up the cutting waste 62. It was.
