An edge portion 15 is formed on the upper surface. 7 to FIG. 9, the portions other than the reference numerals described above and the same reference numerals as those in FIG. 3 to FIG. 5 have the same configurations as those in FIG.

Hereinafter, the operation of the plate material conveying apparatus will be described.
In FIG. 1, a plate material W is conveyed to the plate material conveyance device 1 of the present invention by a plate material supply device 7 shown on the right side. The plate material W slides down along the chute 8 and is temporarily accommodated in a trough formed between the chute 8 and the guide plate 9 of the plate material conveying device 1.

  The feed bar 4 circulates integrally with the feed chain 3, and the feed bar 4 that circulates contacts the plate member W accommodated in the valley from below. Then, as shown in FIG. 2, the feed bar 4 conveys upward along the guide plate 9 while supporting the rear end surface of the plate material W in the conveyance direction. Thus, the plate material W is conveyed one by one by the feed bar 4.

  However, as shown in FIG. 10 (a), there are cases where two plate members W, W are stacked between two feed bars 4a, 4b adjacent to each other in the front-rear direction in the transport direction. Of these stacked plate members W, W, the upper plate member W is supported in contact with the kicking member 10 attached to the front feed bar 4a.

  While the forward feed bar 4a passes through the first inclined transport surface A1, the plate members W and W are transported in a stacked state. However, as shown in FIG. 10 (b), immediately after the front feed bar 4a passes through the bent portion C, the rear end of the kicking member 10 of the front feed bar 4a is located with respect to the first inclined transport surface A1. Swings in the direction of separation. Due to the swinging of the kicking member 10 of the front feed bar 4a, the plate member W leaning on the kicking member 10 is kicked away in a direction away from the first inclined transport surface A1, and falls downward. . Thereby, one plate material W remains on the rear feed bar 4b. Thus, according to the structure of this invention, the board | plate material W piled up unnecessarily can be dropped and removed, and the board | plate material W can be conveyed one by one reliably. Further, the plate material W that has been kicked and dropped is then supported and conveyed by another feed bar 4.

  Although not shown in the drawing, even when three plate members W are stacked on the rear feed bar 4b, two plate members W are dropped from the top of the stacked plate members W by the same action as described above. It is possible to leave only one plate material W on the rear feed bar 4b.

  In addition, as shown in FIG. 11, in the case of another embodiment of the present invention, the plate members W, W stacked on the rear feed bar 4b by the kicking member 10 of the front feed bar 4a are also similar to the above. Among them, the upper plate material W can be kicked out and dropped. In this embodiment, since the kick member 10 has the inclined portion 14, the plate material W can be kicked to a position further away from the guide plate 9 (conveying surface). Further, when kicking out the plate material W, the rear end portion 16 of the inclined portion 14 is in sliding contact with the plate material W. However, since the rear end portion 16 is formed in a convex arc shape, there is no possibility of damaging the plate material W.

  Further, as shown in FIG. 12A, when the plate material W is conveyed to a position near the upper end of the second inclined conveyance path A2, the plate material W may fall forward (horizontal conveyance surface B side). At this time, the rear end portion of the plate material W is separated from the front end portion of the feed bar 4, and a gap S is formed between the guide plate 9. When the feed bar 4 intervenes in the gap S, the feed bar 4 is conveyed under the rear end of the plate member W as shown in FIG. This may hinder smooth and accurate conveyance of the plate material W. Further, depending on how the respective inclination angles of the first inclined conveyance path A1 and the second inclined conveyance path A2 are set, in the bent portion C between the first inclined conveyance path A1 and the second inclined conveyance path A2, the above and A similar feed bar sinking phenomenon may occur.

  Therefore, as in the other embodiments described above, it is possible to solve the above problem by inclining the front end surface of the feed bar 4 to form the acute edge portion 15. That is, as shown in FIG. 13A, the rear end surface of the plate material W can be locked by the edge portion 15. Thereby, it is possible to suppress the rear end portion of the plate material W from being separated from the front end portion of the feed bar 4, and it is possible to prevent the feed bar 4 from entering the plate material W. 13B, when the thickness of the plate material W is set to be thinner than the thickness of the feed bar 4, the rear end portion of the plate material W is attached to the inclined front end surface of the feed bar 4. It is possible to enter and lock.
