A lifter 18 is provided at the right end of the accumulation conveyor 12.
Is provided, and a lifter 19 is provided at the right end of the accumulation conveyor 13.
The traverser conveyor 15 is arranged so as to straddle these lifters 18 and 19.

The empty cans are packed together with the pallets and placed on the entrance roller conveyor 10 by a forklift, where the strings and covers are removed manually.

Thereafter, by driving the inlet roller conveyor 10, a pallet carrying a load formed by stacking empty cans in multiple stages is conveyed onto the accumulator 11, and by driving the accumulator 11, its pallet ends, That is, when the left end is reached, the accumulation conveyor 11
Stops.

Next, after raising the lifters 16 and 17,
The pallet is lifted from the lifter 16 by the traverser conveyor 14 by driving the traverser conveyor 14.
17 is transported on.

Next, when the traverser conveyor 14 is stopped and the lifters 16 and 17 are lowered, the pallet rides on the left end of the accumulation conveyor 12. Therefore, the accumulator
When 12 is driven, the pallet is conveyed by the accumulation conveyor 12, and when it reaches the end of its travel, that is, the right end,
The accumulation conveyor 12 stops.

Next, after raising the lifters 18 and 19,
The pallet is lifted from the lifter 18 by the traverser conveyor 15 by driving the traverser conveyor 15.
19 is transported.

Next, when the traverser conveyor 15 is stopped and the lifters 18 and 19 are lowered, the pallet rides on the right end of the accumulation conveyor 13. Then, when the accumulator 13 is driven, the pallet is stored in the accumulator 13
When it reaches the end of its travel, that is, the left end, it enters inside the depalletizer 20, and the accumulation conveyor 13 stops.
