Therefore, in some cases, the mounting hole for mounting other articles may be used. There is a problem that it is necessary to change the positions of the holes, which is troublesome and increases the manufacturing cost. Although it is conceivable that the bolt hole provided on the stopper plate material 104 side is a long hole, the longitudinal direction thereof coincides with the load direction acting on the stopper plate material 104 when the article is stopped. At the same time, the mounting position of the stopper plate 104 is shifted.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a transport device that can reliably stop an article at a predetermined position without spending extra cost.

It is composed of a stopper plate material to be supported, and the L-shaped bracket and the stopper plate material are connected with bolts and nuts.
In addition, the bolt holes formed in the horizontal portion of each L-shaped bracket and the stopper plate material are formed as long holes, and the longitudinal directions thereof are inclined in directions opposite to each other with respect to the conveying direction of the article.

  In addition, the transport device according to claim 2 is a mounting hole formed in the side plate in advance for mounting the transport roller to attach the L-shaped bracket in the transport device according to claim 1 to the side plate. Is used.

  According to the configuration of the first aspect, the bolt holes provided in the stopper plate member and the L-shaped bracket for mounting the stopper plate are elongated holes, and the longitudinal directions of the bolt holes are opposite to the conveying direction of the article. Since the position of the stopper plate material can be adjusted in the conveyance direction, when the article collides with the stopper plate material, the connecting bolts are inserted into the bolt holes inclined in different directions. Therefore, the bolt is in a state of being supported by the triangular groove from the front and rear in the conveying direction, and thus the stopper plate can be reliably positioned while being a long hole.

  Further, according to the configuration of the second aspect, since the L-shaped bracket is mounted using the mounting hole for mounting the transport roller, it is separately mounted on the side plate material side for the positioning member. Since it is not necessary to form a hole, an increase in cost can be suppressed.
