Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail. In addition, even if shown in the other drawings for the same component having the same function as the conventional component is given the same reference numerals to reduce and omit the description.

Figure 4 is a perspective view showing a knife soft roll device of the side trimmer according to the present invention, Figure 5 is a perspective view showing the operating state of the knife soft roll and hold down roll device of the side trimmer according to the present invention.

The pass of the hold down roll 22 which is installed in front of the side trimming equipment which trims both sides of the strip 60 which proceeds in one direction to the order of demand, and adjusts the anti-shake and the pass line of the strip 60 during the trimming operation. In order to finely adjust the line level finely, the motor 30 with the pulse generator 31 is fixedly installed at an appropriate position, and the coupling 32 and the ball screw 34 are connected to one side of the motor 30. To rotate by driving of the motor 30, the feed stopper 38 is fitted in the center of the ball screw 34, the nut member 36 on one side of the feed stopper 38 to the LS guide 33 Is fitted.

Both sides of the ball skew 34 are installed while the fixing plate 35 is fixed to the LM guide 33. One side of the transfer stopper 38 is touched by the plate 26 connected to the cylinder 21, the hold down roll 22 is fixed to the roll fixing plate 27 is installed up and down in accordance with the operation of the cylinder 21 Then, the up and down sensing proximity sensors 24 and 25 are touched, and the pass line is adjusted according to the level of the transfer stopper 38. The pass line is adjusted by the control of the control panel and driven by the motor 30, and the level thereof is controlled by the pulse generator 31.

As shown in FIG. 5, the L guide 55 is fixedly installed at an appropriate position of the lower trimmer main body of the side trimmer knife 10, and the lower fixing plate 54 is fixed to the upper part of the lower L guide 55 and the upper part is fixed to the upper part. The plate 54 faces each other and is fixedly installed symmetrically. The ball screw 58 is connected to and installed at the vertical center portion of the fixing plates 54 and 54, and both guide bars 59 and 59 are connected to each other with the frame 57 installed horizontally.

A motor 51 having a coupling 53 and a pulse generator 52 attached to the lower end of the ball screw 58 is connected to the ball screw 58 by driving the motor 51 by a separate control device. Is rotated, and the frame 57 fitted to the ball screw 58 is operated up and down.

The nut member 56 is fitted to the LM guide 55 at the L guide 55 side of the frame 57, and on the opposite side thereof, a pin 49 is connected to the rotary shaft 41, and the upper shaft 57 is rotated. On the 41 side, the stopper 48 with the electromagnet 50 attached thereto is fixed to fix the rotating shaft 41 by the operation of the electromagnet 50, and the cylinder 61 is fixed to the bottom of the frame 57 to rotate the rotating shaft. (41) Connect the rod (62) attached to the lower end to the cylinder (61) rod.

In addition, the proximity sensor 47 is installed at the proper position of the home position of the rotating shaft 41 to detect the home position, and the knife soft roll 40 is close to the lower knife 10 at the upper end of the rotating shaft 41. Fixing block 44 is bolted 45 to secure shaft 46 of knife soft roll 40 so that the level is similar. Inside the shaft 46 side of the soft roll 40 is a bearing is built is designed to rotate as an idle roll.

The optical sensor 42 is fixed by the sensor fixing plate 43 at a proper position opposite the knife soft roll 40 of the rotating shaft 41 to automatically measure the level of the strip 60 and then the motor by a separate controller. 51 is designed and manufactured to maintain the knife soft roll 40 level by driving.

Referring to the operation of the present invention of the configuration as described above are as follows.

As shown in FIG. 5, it is installed in front of a power cut type side trimmer facility to impart proper tension to both sides of the strip 60 to prevent hunting and pass lines of the strip 60. The hold down roll 22, which is a facility for smooth trimming by adjusting the pressure, is down by the cylinder 21 by a separate control device during trimming, and is touched by the down sensing proximity sensor 25 while the idle ( idle) to rotate.

At this time, if the pass line is inadequate, various defects such as a bad trimming and a bend mark due to the hold down roll 22 edge are generated. Therefore, the motor 30 is driven by a separate control device to drive the coupling 32 and the ball. Powered to the screw 34, the conveying stopper 38, which is connected to the LM guide 33 and fitted to the ball screw 34, touches the plate 26 fixed to the hold down roll 22 to hold the roll down roll ( When 22) is set to an appropriate level, the pulse generator 31 senses the level and the level is displayed on a panel not shown in the figure.

After the trimming operation, the hold down roll 22 is up and waits for the next operation while touching the up detection proximity sensor 24.

The back trim ring 14 is attached to the side trimmer knife 10 on the side, causing excessive knife replacement time and having a back light ring 14 according to the knife 10. (10) By installing the soft roll 40 to replace the back light ring 14 on the side of the LM guide by the rotation of the coupling 53 and the ball screw 58 by the drive of the motor 51 during the trimming operation It is connected to the nut member 56 by 55.

When the frame 57 connected to the ball screw 58 and the plurality of guide bars 59 moves up and down the rotary shaft 41 on which the soft roll 40 and the optical sensor 42 are mounted, the optical sensor 42 is provided. And the pulse generator 52 automatically check the level of the lower strip 60, and the level is displayed on a panel not shown in the figure to adjust the level of the hold down roll 22 and the soft roll 40. Fit.

In addition, in the trimming operation, the rotation shaft 41 is fixed to the home position by adsorbing and fixing the rotation shaft 41 by the operation of the electromagnet 50 when the soft roll 40 device arrives at the home position position by advancing the cylinder 61. When the sensing proximity sensor 47 is touched, the above operations are automatically performed. When the knife 10 is replaced, the electromagnet 50 is turned off to reverse the cylinder 61 to move the rotating shaft 41. Replace the knife 10 in a state where the soft roll 40 and the like fall outward.

After replacing the knife 10, the cylinder 61 is moved forward to fix the rotating shaft 41 by the electromagnet 50, and the home position detection sensor 47 is touched to wait for the next operation.

As described above, according to the present invention, by installing a soft roll that can automatically adjust the pass line during trimming, cost reduction and knife replacement time can be greatly improved, thereby improving work efficiency.
