An operation description of the strip unit 100 having the above configuration will be described with reference to FIG. 2.

First, since the stainless steel sheet wound in the form of a coil is a heavy body, it cannot be transported by human force. As shown in FIG. 2B, the third piston rod 122 is advanced by the third cylinder 123. When the transfer table 121 is located at the other end of the guide bar 119, the strip coil is placed on the seating roller 124 of the lifting platform 125 using a forklift truck or a crane.

At this time, even if the strip coil is not raised to the mounting roller 124, the at least one of the one side and the other side is rotated so that the strip coil can be placed in the position as shown in Figure 2a.

In addition, since the thickness of the strip coil may vary depending on the number of turns of the strip coil, the fourth cylinder (as shown in FIG. 2A) so that the center circle (bobbin: not shown) of the strip coil coincides with the pressing plate 115. The fourth piston rod 126 is raised and lowered by 127, and the third piston rod 122 is moved backward by the third cylinder 123 so that the center circle of the strip coil is pressed onto the first shaft 101. To be inserted).

Accordingly, when the strip coil is inserted into the pressing plate 115 by the transfer of the transfer table 121, the second piston rod 106 is advanced as shown in FIG. 2C by the operation of the second cylinder 107. The transfer pipe 108 coupled to the connection part 109 slides along the outer diameter surface of the first shaft 101 and is transferred toward the other side. In this case, the first bracket 111 and the second bracket 114 are moved. Is coupled to the guide pin 112 and as shown, the first guide hole 113 of the second bracket 114 is formed obliquely so that the first guide hole 113 is the guide pin 112. Therefore, as shown in FIG.

Here, the guide disc 117 is maintained in a fixed state in the first shaft 101, and a pair of first guides to the front and back of the guide line 116 of the guide disc 117 Since the roller 118 is fixed by the fixing piece 135 at one end of the pressing plate 115 as shown in FIGS. 2A, 2C, and 2D, the pressing plate 115 has a second bracket 114. At the same time as the lifting and lowering of), as shown in FIG. 2C, the first guide roller 118 of the guideline 116 is raised and lowered.

Therefore, the plurality of pressing plates 115 coupled to the transfer pipe 108 are expanded simultaneously with the advancement of the second piston rod 106 to compress the center circle (bobbin) or the inner diameter surface of the strip coil to the first shaft ( 101) to allow the strip coil to be fixed.

In addition, as the first motor 103 is driven, the first shaft 101 is rotated by the first driving gear 104 and the second interlocking gear, and the guide disc is formed on the first shaft 101. As the first guide roller 118 is rotated while the 117 rotates in a state in which the first guide roller 118 is coupled to the guide line 116, the pressing plate 115 and the feed pipe 108 rotate, and the connection portion (B) is rotated by the feed pipe 108. 109 is rotated.

At this time, since the second piston rod 106 is externally wound from the connecting portion 109 to the radial bearing 131, the rotational force of the first motor 103 affects only the connecting portion 109 and the second piston rod 106. Since it does not affect the second piston rod 106 will be able to maintain a fixed state.

In this case, as shown in FIG. 2C, the other side of the pressing plate 115 protrudes the stopper 136 having a predetermined size, thereby preventing the possibility of the strip coil fixed to the pressing plate 115 slipping as it rotates. It is desirable to.

The upper cutter 301 is lowered together with the upper transfer body 310 to cut the strip as the seventh piston rod 303 moves forward and the seventh cylinder 304 descends.

Here, a micro sensor (not shown) is installed at one end of the second base 201 to measure the length of the strip introduced into the first and second calibration rollers 202 and 203 of the calibration unit 200. In addition, the value measured by the microsensor is sent to a controller (not shown) to control the reciprocation of the seventh cylinder 304, so that the cutting operation of the strip according to the lowering of the upper cutter 301 is performed. .
