And a light receiving portion 5B for receiving the light. Accordingly, if the light receiving unit 5B cannot receive the light emitted from the light emitting unit 5A when it strikes the sheet F, the control device U determines that the sheet F is being detected, and the light from the light emitting unit 5A When the irradiated light is received by the light receiving unit 5B without hitting the sheet F, the control device U determines that the sheet F is not detected.

  Alignment of the edges in the width direction of the sheet F by the cross guider device 106 having the above configuration will be described. First, the left and right lower sandwiching rollers 7 and 7 are moved downward and separated from the left and right upper sandwiching rollers 6 and 6 by a manual force (or electric force by an actuator). The width direction end of the sheet F fed in this state is inserted between the upper and lower sandwiching rollers 6 and 7, and then the left and right lower sandwiching rollers 7 and 7 are returned to their original positions, whereby the sheet F is disposed in the width direction. The both ends are clamped by the left and right clamping rollers 6 and 7, and the sheet F is set to be wound around the winding unit 104, and the production of the sheet F is started.

  The cylindrical resin foam 101 cooled by the cooling mandrel 103 is sent to the downstream side in the feed direction and immediately cut by the cutting portion 111 at one lower portion in the circumferential direction. Then, the cut resin foam 101 is developed into a sheet F by the developing roll 105 while being continuously sent to the lower side in the feeding direction, so that the developed sheet F is further developed by the cross guider device 106. At the same time, the edges in the width direction of the sheet F are aligned. The aligned sheets F are conveyed to the downstream side in the feeding direction and are sequentially wound around the winding unit 104.

  Since both ends in the width direction of the resin foam 101 cut at one place by the cutting portion 111 are sandwiched between the left and right sandwiching rollers 6 and 7, the resin foam 101 is prevented from shaking unexpectedly. be able to. Therefore, the cutting position of the resin foam 101 can be stabilized (matched) at a predetermined position, and the resin foam 101 can be wound in a state in which the side edges in the width direction are aligned with the winding portion. Moreover, the width direction edge of the resin foam 101 can be well wound around the winding portion 104 on the rear side of the sandwiching rollers 6 and 7 (downstream in the feed direction of the resin foam 101).

  Further, the positions of both ends of the sent resin foam 101 are detected by the left and right sensors 5, 5, and based on the detection signal, one of the sandwiching rollers 6, 7 is rotated to one of the sandwiching rollers 6. , 7 can be changed to increase or decrease the tensile force in the width direction of the resin foam 101 by one of the sandwiching rollers 6, 7. Therefore, it is possible to accurately correct the positional deviation in the width direction of the side edge in the width direction of the resin foam 101.

  Specifically, as shown by the solid line in FIG. 2, when the sheet F is sent out, both the left and right sensors 5 and 5 are in a state of detecting the sheet F satisfactorily. Therefore, as shown by the solid line in FIG. 2, both the left and right nip rollers 6 and 7 (the lower nip roller 7 is not visible because it is wrapped vertically with the upper nip roller 6). The sheet F is guided in a state parallel to the width direction of F.

  In addition, when the sheet F is sent out as shown by a one-dot chain line in FIG. 2, the right sensor 5 detects the sheet F and the left sensor 5 does not detect the sheet F. . Then, the control device U determines that the sheet F has been displaced to the right side, and as shown by the solid line in FIG. 2 (shown on the left side by a one-dot chain line) and the solid line in FIG. The sandwiching roller 7 is not visible because it is wrapped up with the upper sandwiching roller 6 in the vertical direction (inside the sheet width direction), and is inclined to the downstream side in the sheet feeding direction (right sandwiching roller 6, 7 is left in a posture parallel to the width direction of the sheet F). As a result, the tensile force that pulls the sheet F of the left nip rollers 6 and 7 outward in the width direction becomes strong, and the sheet F can be forcibly moved to the left side, and the width direction edge of the sheet F can be accurately positioned. Can be aligned.

  In contrast to the above, when the sheet F is sent out as indicated by the broken line in FIG. 2, the left sensor 5 detects the sheet F and the right sensor 5 does not detect the sheet F. It becomes. Then, the control device U determines that the sheet F is displaced to the left side, and as shown by the broken line on the right side of FIG. 2, the right side holding rollers 6 and 7 (the lower side holding roller 7 is the upper side holding roller 6). (Not seen) because the inner side in the sheet width direction is inclined toward the downstream side in the sheet F length direction (the left sandwiching rollers 6 and 7 are arranged in the width direction of the sheet F). Leave it in a parallel position). As a result, the tensile force that pulls the sheet F of the right nip rollers 6 and 7 outward in the width direction becomes strong, and the sheet F can be forcibly moved to the right side, and the width direction edge of the sheet F can be accurately positioned. Can be aligned.

  Note that the installation angle range of the sandwiching rollers 6 and 7 may be configured to gradually correct the misaligned sheet F, for example, by setting it to about 4.6 to 5.8 degrees. It can also be carried out by setting an installation angle range exceeding 10 degrees. As the installation angle of the sandwiching rollers 6 and 7 is increased, the tensile force in the width direction of the sheet F by the sandwiching rollers 6 and 7 can be increased.

  The sheet foreign matter removing apparatus according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

  In the above embodiment, the photoelectric sensor is used as the detecting means for detecting the position in the width direction of the resin foam. However, in addition to a non-contact sensor such as an ultrasonic sensor, a contact sensor such as a limit sensor is used. A sensor may be used.

  In the above embodiment, the detection means for detecting the position in the width direction of the resin foam is arranged on both sides in the width direction of the resin foam. However, the detection means is arranged only on one side in the width direction of the resin foam. The position of the width direction edge of a foam may be detected, and the width direction position of a resin foam may be grasped | ascertained from the position detection information.

  Moreover, in the said embodiment, although it was the structure which restrict | limits the installation angle of the clamping rollers 6 and 7 using the angle limitation means 22 comprised from a mechanical mechanism, by restrict | limiting the expansion-contraction area | region of a cylinder by software. The structure which restrict | limits the installation angle of the clamping rollers 6 and 7 may be sufficient.

  Further, in the above-described embodiment, when the sheet F is displaced, only the installation angle of one of the left and right sandwiching rollers 6 and 7 is adjusted, and only one end side of the sheet F is pulled. However, a configuration in which both ends of the sheet F are pulled by adjusting the installation angles of both the right and left sandwiching rollers 6 and 7 may be adopted.

  In the above-described embodiment, the sandwiching rollers 6 and 7 are configured to be movable by a manual operation force in the width direction of the sheet F according to the width of the sheet F, but the sheet according to the width of the sheet F using an electric force. The sandwiching rollers 6 and 7 may be automatically moved in the width direction of F. In the case of a dedicated sheet manufacturing apparatus in which the width of the sheet F is determined to be a predetermined width, the sandwiching rollers 6 , 7 may be configured to be immovable.

  In the above-described embodiment, the rotation start position is a state in which both the left and right sandwiching rollers 6 and 7 are in a posture parallel to the width direction of the sheet F. The tilted position (position in the shape of a letter C) located on the downstream side in the sheet length direction may be set as the rotation start position, and what is the attitude at the rotation start position of the left and right clamping rollers 6 and 7 May be set.
