It is done by rotating 5, 30 all at once,
In any case, the movable rails 4, 12, and 26 are moved from their current positions to the fixed rails 2, 10, and 23 by a predetermined amount and then moved to a predetermined position, and then moved to an initial position (a position where a printed circuit board having a minimum width can be conveyed). : Refer to FIG. 2), and then control is performed to spread to the set position. Therefore, even if there is a printed circuit board left on the conveyor belt when the movable rail is set, the printed circuit board will drop under its own weight when the movable rail expands. There is nothing to do. The conveyors D and E operate in the same manner, and their movable rails are set so as to be aligned with the movable rails 4, 12, and 26.

Thus, when the printed circuit board P is stopped at the inspection position,
The optical sensor 18 senses it, and the output signal urges the electromagnetic plunger 20 to actuate the air cylinder 22 so that both side edges of the printed circuit board P are pressed against the rails 10 and 12 by the pressing plate 19, and the air mat is formed. Two
Reference numeral 1 uniformly presses the printed circuit board P upward so that the printed circuit board P can be kept stationary.

When the inspection is completed, based on the completion signal, the air cylinder 17 operates, the stopper 16 is pulled down to the outside of the conveyance path, the bias of the electromagnetic plunger 20 is released, and the pressing plate 19 is lowered to the chain line position, and the air cylinder 22 works again to release the pressure on the air mat 21. Then, the conveyor belt 1 which is activated again
1 and 13, the inspected printed circuit board P is sent to the sorting and collecting section C via the conveyor E.

れる。On the other hand, based on the end signal, the air cylinder 9 operates and the stopper 8 is pulled down to the outside of the conveying path, and at the same time, the belt conveyors 3 and 5 are activated.
The printed circuit board P, which has been placed in the standby state in the loading section B, is sent to the inspection position by the conveyor D and the belt conveyors 11 and 13 of the inspection section A which are not shown in FIG. Then, the appearance inspection is performed in the same manner as described above, and after the inspection, it is sent to the sorting and collecting department C.

繰り返される。The air cylinder 9 is switched to the operating state after receiving a signal from the sensor 18 emitted when the printed circuit board P sent in as described above reaches the inspection position, and the air cylinder 17 is operated as described above. After the inspection end signal is received, the operating state is switched, and the stoppers 8 and 16 are made to project again into the conveyance path. As a result, in the carrying-in department B, the printed circuit board P sent next is stopped, and in the inspection department A, the printed circuit board P sent in is stopped at the inspection position. After that, this operation is repeated.

ても良いことは云うまでもない。The printed circuit board P sent to the sorting / collecting section C as described above is based on the signal generated when the inspection section A determines that the printed circuit board P is defective at the initial stage of transportation, and the electromagnetic plunger 28 is then sent. Is momentarily urged, the movable rail 26 is moved in the direction of the arrow in FIG. 2, and the interval between the conveyor belts 23 and 27 is momentarily widened. Therefore, the printed circuit board P falls by its own weight and is collected. On the other hand, when the inspection department A determines that the product is a good product, when the printed circuit board P reaches the final position of the sorting and collecting department C, the interval between the conveyor belts 23 and 27 is momentarily widened,
It falls and is collected by a non-defective stocker. As is clear from this description, the good product and the defective product may be collected separately at different positions of the transport path, and the good product is collected in the initial stage of the transport and the defective product is collected in the latter stage of the transport. It goes without saying that you can do this.
