Title:
TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/276993
Kind Code:
A1
Abstract:
The present invention provides a transfer device with which, even if an object to be conveyed is heavy, it is possible to transfer the same in a stable manner. The present invention comprises: a main conveyor having a main-conveyance path and a main-conveyance cam follower; an auxiliary conveyor having an auxiliary-conveyance path and an auxiliary-conveyance cam follower; and a lifting mechanism. The main-conveyance path and the auxiliary-conveyance path overlap partially or entirely in plan view. The lifting mechanism comprises a first horizontal movement member having a first linear-motion cam, a second horizontal movement member having a second linear-motion cam, and a drive source. By operating the drive source, it is possible to perform a position change operation in which the main-conveyance cam follower travels on the first linear-motion cam, the auxiliary-conveyance cam follower travels on the second linear-motion cam, and one of the main-conveyance path and the auxiliary-conveyance path rises, with the other dropping down. Rotary shafts of the main-conveyance cam follower and the auxiliary-conveyance cam follower are configured so as to have a portion of overlap with the auxiliary-conveyance cam follower on a projected plane in the vertical direction during the position change operation.
