The stopper member 26 ′ contacts the conveyance object W carried in along the carry-in direction p ′ from each shooter unit 50 and positions it in the carry-in direction P ′. Further, the transfer means 12 ′ is in a predetermined direction so as to be able to abut on the rear side surfaces in the transfer direction q ′ of the conveyance object W placed on the support portions 10a ′ and 10b ′. The protruding contact members 31a ′ and 31b ′ and a moving mechanism 33 ′ that moves the contact members 31a ′ and 31b ′ along the transfer direction q ′ are provided. The contact members 31a 'and 31b' are suspended so that their tips protrude downward. Each pair of contact members 31a ′ and 31b ′ moves by a predetermined stroke along the transfer direction q ′, so that the transport object W on the support portion 10a ′ located on the transport conveyor unit 6 side becomes a pair. While being pressed by the contact member 31a ′ and transferred onto the transport conveyor unit 6, the transport object W on the support portion 10b ′ located on the side away from the transport conveyor unit 6 is transferred to the pair of contact members 31b. It is pushed and transferred onto the support part 10a 'located on the side of the conveyor section 6. Then, after a predetermined amount of the transport object W transferred onto the transport conveyor unit 6 is unloaded, the contact members 31a ′ and 31b ′ are further moved by a predetermined stroke along the transfer direction q ′. The transport object W transferred onto the support portion 10a ′ located on the transport conveyor section 6 side in the previous stroke is pushed onto the transport conveyor section 6 by being pushed by the contact member 31b ′. . That is, the conveyance object W respectively supported by the plurality of support units 10a ', 10b', ... is sequentially transferred to the single conveyance conveyor unit 6 and is carried out.
