JP 2001-320959 A [Patent Document 2]
For example, regarding handling at the time of sorting flower buds, it is necessary to leave a space between floret stalk bundles to avoid contact, and thus lay the stalk bundles as in Patent Document 1. There is an example of handling in a horizontal position, but the structure is complicated and a dedicated transfer machine and a large space are inevitable. On the other hand, a stacker type warehouse system can be applied when a stem bundle is inserted into a bucket and handled in a vertical posture. The stacker type warehouse system is composed of a transfer device for storage and storage and a storage shelf, and can store / unload storage objects between the storage port and the storage shelf by a reciprocating operation of the transfer device. However, since the stacker type warehouse handles the objects to be stored individually via the transfer machine, it takes a round-trip time for the transfer machine for each loading / unloading operation, and one handling of the load ends. In the meantime, since other cargo handling cannot be performed, it is not suitable for high-speed large-volume storage / removal processing. In order to increase the speed, it is necessary to increase the moving speed, and it is not particularly suitable for a soft material such as a bridegroom.
Patent Document 2 is an example of a storehouse device, in which a store object is temporarily retained on a conveyor, thereby enabling continuous store with a space in front and back.
