FIG. 1 shows a typical example of a conventional separator cutting device. In the figure, 1 is a fixed base on which the lower blade 2 is fixed, and 3 is a rectangular frame-shaped movable member on which the upper blade 4 is fixed at the tip. It is movably attached and reciprocated back and forth by an actuator 6. 7 is a separator, which is adapted to be unwound from a reel, and includes a separator drawer member (not shown).
The movable member 3 rises from below the lower blade 2 and pinches the tip of the separator 7, and then pulls out the separator downward along the lower blade 2. At this time, the movable member 3 retreats and is moved by the upper blade 2 and the lower blade 4. The separator is then cut to a certain size.

In addition, in the method of cutting with two blades, in order to reduce the cutting resistance, it is usually necessary to give one blade an inclination (shear angle) as a scissor so that the two blades do not intersect at the same time across the entire width. Therefore, the cut surface becomes oblique. For this reason, when the separator is folded in half and sealed on both sides to form a bag-like bag, problems arise such as the opening edges not matching up. Further, the length of the separator is determined by the length of the drawer by the drawer member, but there is also a drawback that the length of the separator is not constant because the separator may stretch or sag in relation to the drawing out of the separator.

Structure of the Invention The separator cutting device of the present invention includes a pair of feed rollers that sandwich a long strip-shaped separator and feed it in the longitudinal direction, and a pair of feed rollers that sandwich the separator fed by the feed roller and cut it into a fixed size. one of the cutting rollers is provided with a serrated cutting blade protruding from its circumferential surface and a separator pressing member that can protrude and retract on both sides thereof, and the other of the cutting rollers is provided with the cutting blade. A receiving recess is formed by pressing pieces arranged on both the left and right sides of the recess.

In the device of the present invention, both the feed roller and the cutting roller rotate in one direction, so it is easier to increase the speed compared to conventional intermittent drive type devices. Since it is possible to eliminate this, it is possible to always obtain a separator of a constant length. In particular, one of the cutting rollers has a recess on both sides of the cutting blade, and a separator pressing member that is biased by a spring so as to protrude to almost the same position as the cutting edge of the cutting blade, and that can retreat to the circumferential surface of the roller. If the other cutting roller is provided with a piece that presses the separator pressing member through the separator,
Since the separator is pressed against the serrated cutting blade while the left and right sides of the cut portion are restrained, the cutting quality is good, and a separator of a fixed size can be obtained without any problem even during high-speed operation.
Here, it is preferable that at least one of the pressing member and the pressing piece is made of a member having a large coefficient of friction in view of cutting the separator to a certain size.

First, the separator 10 that has been unwound from the reel with a margin is sandwiched between the feed rollers 11 and 13, and is fed to the cutting roller at a speed that corresponds to the circumferential speed of the rollers. The cutting rollers 16 and 22 rotate at the same circumferential speed as the feed roller, and the separator 10 sandwiched between the rollers 16 and 22 is first folded by the ridges 21 and the recesses 25 as shown in FIG. (See Figure 5). Then roller 16,
After half a rotation of the roller 16, as shown in FIG. Next, when the pressing member 20 and the pressing piece 24 of the roller 22 come to corresponding positions, the pressing member 20 gradually retreats, but its spring pressure firmly presses the separator against the pressing piece 24. Further, as the roller rotates, the pressing member 20' located at the same position as the cutting edge of the cutting blade 17 is also pressed by the pressing piece 24' and retreats sequentially, and the cutting blade 17 is exposed and the cutting edge is bites into the separator 10. When the roller further rotates and comes to the position shown in FIG.
Since the cutting blade 17 is pressed against the cutting blade 17 while being held between the pressing pieces 24 and 24', it is instantly cut. FIG. 4 shows the state after the separator has been cut, and the pressing members 20, 20' have returned to their original states by their spring pressure. The separator thus cut to a predetermined length is creased by the ridges 21 and recesses 25 of the cutting roller before cutting, and then folded into two in the next step.
It can be assembled into a bag by folding it in half and sealing both edges.

In the present invention, since a serrated cutting blade is used, the cutting edge is triangular and sharp, and the cutting resistance is small because the cutting force is pressed and cut by the cutting edge, and the pressure contact force between the rollers 16 and 22 is not increased so much. Can be cut. In this case, it is desirable that the separator be firmly pressed before and after the cut portion.
