Abstract

PURPOSE:To permit situation correction with a simple apparatus by correcting the situation by attaching a conveyed article onto a situation correcting member which possesses springiness during the time when the conveyed article is transported by the transportation force applied onto the near center of the conveyed article and then carrying-out the conveyed article by pressing and opening said situtation correcting member. CONSTITUTION:A pair of upper and lower rollers 3 and 4 are rotatably installed in close to a hole 2a formed at the near center, having a guide plate 2 which forms a transport passage for a conveyed article 1 interposed, and the upper- roller 4 is installed in upwardly movable ways against a compression spring so that the interval between the lower roller 3 is varied. A situation correcting member 7 which possesses a proper springiness is arranged at the symmetrical position on the both sides of the rollers 3 and 4, on the downstream side of these rollers 3 and 4, and the upper edge part is fixed onto the apparatus body, and the lower edge part is inserted into the hole 2b formed on the guide plate 2. The tilt is corrected by attaching the conveyed article 1 transported by the upper and the lower rollers 3 and 4 onto the both situtation correcting member 7 and then carried-out by transportation rollers 8 and 9.

修正される方向に向く。Now, when the transport rollers 3 and 4 and the delivery rollers 8 and 9 are rotated in the directions of the arrows by a drive source (not shown), the transport rollers 3 and 9 are rotated so that the transport force is applied to the central part.
The conveyance object 1 sent between the two conveyor rollers is conveyed in the direction of the arrow by the pair of conveyance rollers. At this time, if the conveyed object 1 is traveling obliquely as shown by the solid line in FIG. 2, the right side of the front end of the conveyed object 1 first comes into contact with the attitude correction member 7. The posture correction member 7 has appropriate rigidity and applies a force to the conveyed object 1 to prevent its progress. Therefore, the conveyed object 1 receives a couple force from the posture correction member 7 and the conveying rollers 3 and 4, and rotates in the direction of the arrow in FIG. 2 using the contact portion as a fulcrum. At this time, the force applied by the posture correction member 7 is the force necessary to rotate the conveyed object 1 described above, and the force is small. Thereafter, the conveyed object I rotates while being prevented from moving straight by the attitude correction member 7, so that it faces in the direction in which the inclination is corrected.

すものである。The conveyed object 1 is normally conveyed without being skewed after the skew correction or from the beginning, and the front end both sides are the left and right attitude correction members 7.
After contacting the object 7, the object 1 cannot rotate, and all the transfer force applied to the object 1 becomes the advancing force of the object 1, and the object 1 advances while pushing the attitude correction members 7 apart as shown by the chain line. do. Then, the pushed open posture correction members 7, 7 guide the conveyed object 1 and properly transfer it between the delivery rollers 8, 9.

It has such rigidity that it can be bent by the feeding force received from 3 and 4) and the conveyed object l can pass through it.

are also transported in the same direction. At this time, if the conveyed object 1' is placed on the conveyor belt I in an oblique manner as shown by the solid line in FIG. Thereafter, due to the conveying force applied to the center width by the protrusion 11a, the hook is placed on the conveyor belt 11, which has a sufficiently small coefficient of friction, with the front left side in a posture as shown by the chain line in FIG. The skew is corrected by rotating until it comes into contact with the correction member 12.
