PURPOSE: To efficiently perform the storage work and the pick-up work of a canister bagged in a tea factory, by driving the loop of an endless chain, mounting many canister-loading buckets in a predetermined pitch, to be intermittently moved and stopped.

CONSTITUTION: Two rows of endless chains 5, being tensely provided between a set of left and right and upper and bottom sprockets 2 secured to many axes 1, turnably support buckets 10. A reduction motor 20, actuating a set of the axies 1 serving as a vertical axis 1', normally and reversely rotates or stops a loop A of the chain 5. The motor 20 is stopped by engaging an engaging piece 14 of the bucket 10 with a limit switch 30, and a supply device 32 intermittently drops a canister one by one to be supplied to the bucket 10 stopped in a stop position. The device 32, confirming the canister for whether or not it exists on the bucket 10 by a sensor 34, prevents the next canister from being supplied if the canister is loaded. The bucket 10, being inverted by engaging an inverting lever 41 in a pick-up device 40 with a guide roller 15 of the bucket 10, drops down the loaded canister.
