Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the longitudinal direction of the sticking plate 1 by suctioning the sticking plate 1 to the lower surface with a suction chamber 3 above the lower conveyor 2 which conveys the sticking plate 1 in the transverse direction (arrow A). An upper conveyor 4 for conveying in the direction (arrow B) is provided, and a table lifter 5 is arranged below the upper conveyor 4 for pushing up the plate 1 conveyed by the lower conveyor 2 and causing it to be sucked by the upper conveyor 4. In the device for changing the conveyance direction of a plate, at least one of the suction chamber 3 and the table lifter 5 is divided into a plurality of parts in the longitudinal direction (arrow B) of the plate 1, and each divided portion 5a, 5b, 5c, . . . are controlled independently, and the attached plate 1 is adjusted to the front end 1 in the longitudinal direction (arrow B).
This relates to a device for changing the conveyance direction of a peg board, which is characterized in that the ply plate is suctioned by an upper conveyor 4 sequentially from a to the rear end 1b, and its purpose is to prevent wrinkles from forming on the ply board when changing the conveyance direction. It is an object of the present invention to provide a device for changing the conveyance direction of a plate with no problem.

Conventionally, this type of plate conveyance direction changing device is as shown in FIG. By being pushed upward by table lifters 5a', 5b', and 5c' disposed below the upper conveyor 4, it is sucked by the suction chamber 3 of the upper conveyor 4 and conveyed in the longitudinal direction (arrow B). Ta. In this case, table lifter 5
a', 5b', and 5c' are designed to move up and down synchronously, and the attached plate 1 is raised while being held in a substantially horizontal state, and the suction chamber 3 of the upper conveyor 4, which is always in a suction state, It was supposed to suck the plate 1. However, in such a conventional example, when the entire plate 1 is suctioned by the suction chamber 3 at the same time, it appears that the plate 1 is sucked onto the upper conveyor 4 without wrinkles; In reality, there is some difference between the table lifter rising speed and the pinning board rising speed, that is, the pinning board suction speed, so the pinning board becomes free in the process of being transferred from the lower conveyor 2 to the upper conveyor 4. The disadvantage is that the plate 1 tends to wrinkle as each part of the plate 1 gets used to being sucked into the upper conveyor 4 in an unchanging manner. For example, when the front and rear end portions are suctioned and then the central portion is suctioned, wrinkles occur. The present invention has been made in view of the above drawbacks.

Examples will be described below using figures. Second
The figure shows one embodiment of the present invention, where 2 is a lower conveyor, and a suction chamber 6 sucks the plate 1 onto the upper surface of a flat belt 7 and conveys it in the transverse direction (arrow A). Reference numeral 4 denotes an upper conveyor disposed above the lower conveyor 1, and the attached plate 1 is sucked onto the lower surface of the flat belt 8 by a suction chamber 3 and conveyed in the longitudinal direction (arrow B). 9 is a conveyance roller. Reference numeral 5 designates a table lifter which pushes up the plate 1 conveyed by the lower conveyor 2 and causes it to be sucked by the upper conveyor 4, and is disposed below the upper conveyor 4.
This table lifter 5 is divided into a plurality of pieces in the longitudinal direction (arrow B) of the mounting plate 1. Each division 5a
~5i are designed to be controlled independently, and are driven in the order of 5a, 5b, 5c,...
As shown in Fig. 2c, the plate 1 is successively pushed upward in the longitudinal direction (arrow B) from the front end 1a to the rear end 1b, and is suctioned by the suction chamber 3 of the upper conveyor 4. The plate 1 is sequentially delivered to the upper conveyor 4 from the front end 1a to the rear end 1b in the longitudinal direction (arrow B), so that the plate 1 is not wrinkled.

FIG. 3 shows another embodiment in which the suction chamber 3 is divided into a plurality of parts in the longitudinal direction of the mounting plate 1, and each divided part 3a to 3f is provided with a suction control valve that is driven independently. are provided, and the suction operation is performed in the order of 3a, 3b, 3c, . It is designed to attract 4.
In the figure, 3g is a constant suction portion, and table lifters 5a', 5b', and 5c' move up and down synchronously as in the conventional example.

FIG. 4 shows still another embodiment, in which the suction chamber 3 and the table lifter 5 are each divided into a plurality of parts, and each divided part 3a to 3f, 5a to 5i is
are controlled independently, and the table lifter 5 operates in the same manner as the embodiment shown in FIG.
The suction chamber 3 operates in the same manner as the embodiment shown in FIG. 3, and is designed to more reliably suck the plate 1 toward the upper conveyor 4 from the front end 1a toward the rear end 1b.

The present invention is configured as described above, in which at least one of the suction chamber and the table lifter is divided into a plurality of parts in the longitudinal direction of the mounting plate, each divided part is controlled independently, and the mounting plate is controlled in the longitudinal direction. Since the upper conveyor sequentially suctions from the front end to the rear end, when the conveyance direction is changed, each part of the perforation board is suctioned by the upper conveyor in sequence, unlike in the conventional example, thereby preventing wrinkles on the perforation board. It has the advantage of not having to stop by.
