The belt conveyor (2) at the upper part of the underframe (8)
A guide fence (24), which is substantially equal in length and parallel to the belt conveyor (22), is provided on the horizontal portion (23a) of both mounting plates (23) bent in a lateral L-shape laid on both outer sides of 2). There are provided two pairs of photoelectric sensors (25) which form a left and right pair for detecting an object to be transported at both ends thereof.

At the front and rear ends of a vertical portion (23b) of both mounting plates (23), the bases of a pair of left and right rotating plates (26) are pivotally supported. The end is an angle-shaped engagement plate (27)
Play piece connected with the base piece (27a)
An engagement groove (28) is cut out from the edge near both ends of (27b), and a crossover roller (29) is arranged between the free ends of the two rotating plates (26) in line with the engagement plate (27). ) Is pivoted.

As shown in FIGS. 3 and 4, the end surfaces of the roller conveyor (31) for transporting the container (30) accommodating a large number of members correspond to the engagement grooves (28) of the engagement plate (27). An engagement protrusion (32) is protruded at the location, and an annular groove (32a) with which the engagement groove (28) can be engaged from above is cut out of the engagement protrusion (32).

The front and rear rotating plates (26) are linked by a link (33) so that both engaging plates (27) and both transfer rollers (29) are connected.
