サイドトリミング装置を使用した走間巾変え要領
を片側のトリマについて示した平面図である。BACKGROUND TECHNOLOGY In general, in equipment for surface treatment of strips such as pickling lines, when performing side trimming of different width materials in which strips of different width dimensions are successively joined as shown in Fig. 3, when the line is operated A means for trimming in response to changes in board width without stopping, ie, a method for changing the running width, has been developed, and an example thereof will be explained with reference to FIGS. 3 and 4. This figure is based on the patent application proposed by the applicant earlier.
58-119308 (Japanese Unexamined Patent Application Publication No. 60-9613) is a plan view showing the procedure for changing the running width using the side trimming device for one side of the trimmer.

ツプの歩留向上を計らんとするものである。 The gist of this device is that in a rotary (turret type) side trimmer 3 equipped with a pair of upper and lower rotating disc type cutter knives 1, 1' and another pair of spare cutters 101, 101', these two pairs of cutter knives With the center of symmetry 0 as the center axis of rotation,
Such a knife and knife shaft 2, 2', 102, 1
02' horizontally around the turning center 0, and horizontally moved in the width direction VX to perform continuous cutting while changing the running width. The aim is to make it possible to perform both processes using the same mechanism, thereby improving the operating rate of the equipment and the yield of strips.

ができる。 To explain the procedure for changing the width below, the joining part 12 of the strips 10 and 11 of the preceding and succeeding coils is connected to the leading strip 1 before reaching the cutter knives 1 and 1'.
Along a smooth arbitrary curve 15 touching each of an arbitrary position a1 on the cutting line 13 of 0 and an arbitrary position ao on the cutting line 14 of the subsequent strip 11, and always along the upper and lower cutter knife axes 2a, 2a The cutter knife 1 moves as a 1 , a 2 ...a o so that ' is almost perpendicular to the tangent to the curve 15 at each cutting point.
1' and the knife shafts 2, 2' are rotated around the rotation center 0 and moved horizontally in the width direction of the plate while continuous cutting is performed. In this case, the horizontal rotation speed W and horizontal movement speed VX of the cutter knives 1, 1' are appropriately controlled relative to the line speed VY . That is, the width of the running time can be changed and the cutting knives 1, 1' of the side trimmer can be changed by the rotation drive device 5 and the horizontal movement device 8, which are capable of horizontally rotating the cutting knives 1, 1' and the knife shafts 2, 2' around the axis 0. Axis line 2a,
Smooth trimming can be achieved by controlling the rotation angle and horizontal movement speed so that 2a' is approximately perpendicular to the tangent to the running cutting curve 15 at the cutting point.

止時間が問題となつている。Problems to be Solved by the Invention When the knife is changed due to wear of the cutter knife during trimming with such a trimmer, the strip is usually cut at the side-clipped position (see Figure 4) or at the side-clipped position (see Figure 5). As shown, after the line is stopped at the width changing position where the strip changes from the wide material 10 to the narrow material 11, the trimmer body 3 is horizontally rotated 180 degrees and replaced with spare knives 101, 101'. Therefore, a side clipping operation is required for changing the blade, and the line down time for this operation becomes a problem.

ある場合は問題ないが、遠い位置にある場合に

とになり、この間、トリミング性能低下により生
産能率を阻害する要因となる等の問題がある。 In addition, changing the blade at the width changing position as shown in Figure 5 is not a problem if the position is upstream near the side trimmer, but if it is far away, it will take longer to start changing the blade. During this time, there are problems such as deterioration of trimming performance, which becomes a factor that inhibits production efficiency.

制御する。Embodiment In FIGS. 1 and 2, members that are the same or similar to those of the conventional apparatus shown in FIGS. 3 to 5 are given the same reference numerals as those of the conventional apparatus, and detailed explanations thereof will be omitted. The trimmer shown in Figure 1 was originally proposed by the applicant in a patent application.
It has the same structure as the turret type side trimmer shown in the specification of No. 58-119308, and while trimming the strip 10 along an arbitrary set cutting line 13, at an arbitrary cutting position a1 , for example, the cutter knife 1,
When the knives 1, 1' are removed from the strip 10 for reasons such as replacement of the cutter knives 1', the line speed V Y is decelerated appropriately, and the horizontal rotation of the cutter knives 1, 1' is made in accordance with the line speed. The scrap 10a is stripped by continuing cutting along an arbitrary set curve 13a, such as the shaded area in FIG. 1, by appropriately controlling the direction and speed W and the direction of horizontal movement and speed VX . It can be easily removed by cutting it off from the 10 ends. In this case, the line speed V Y is controlled so that the line stops near the point where the cutter knives 1, 1' almost complete cutting off the scrap 10a (point a2 in FIG. 1).

ればトリミングが再開できる。 Therefore, the knife can be replaced easily by horizontally rotating the trimmer body 3 by 180 degrees with respect to the original cutting position a1 , without causing the knife pairs 1, 1', 101, 101' to interfere with the strip 10. The cutting line can be accurately set on the set cutting line, and trimming can be resumed by starting the trimmer and line according to known procedures.

可能である。 FIG. 2 is a slightly exaggerated illustration of the state in which the cutter knife is replaced when the scrap is cut along the cutting curve 13a in FIG. Because of this, at the cutting start point a 1 ', the blade surfaces of the knives 101, 101' cross the edge of the strip 10 by an angle α, making it possible to start cutting smoothly.

一層の省力化を図ることができる。Effects of the Invention As is clear from the above explanation, by using the present invention, the knife of the turret type side trimmer can be replaced without the need for side clipping each time, and at any stripping position during line operation. This can be done extremely easily and quickly by simply stopping the line, so compared to the conventional turret type side trimmer, the line stoppage time due to blade changing work is significantly shortened, and further labor savings are achieved. I can do it.
