(52) is lowered to raise and then lift the lifting pallet 30, the transfer clamp 52 by the operation of the transverse cylinder 54 of the upper carrier 50 is the carrier frame (10a) Pallet spacer 32 of the lifting pallet 30 first transported while the transfer clamp 52 is lowered by the operation of the transfer clamp lifting cylinder 51 in the state moved to the highest position of the downward passage along the ), The lifting pallet 30 is put down and returned to the original home position. By repeating the same operation of the upper carrier 50, the subsequent lifting pallets 30 are continuously stacked in the downward passage, and gradually transferred downward one by one.

When any lifting pallet 30 moved above the downward passage reaches the lowest point of the downward passage, the stacking clamping device 39 operates to release the gripping state, thereby causing the lifting pallet 30 to be released. Dropping (falling) rests on the pallet lifting platform 37 of the pallet lifting cylinder 35 provided on the pull-out chain conveyor 62, and the lifting pallet 30 is attached to the gripping and transporting unit 80. As a result of being moved onto the supply / conveyor conveyor 70, all cooling transfer flows of the product 1 are completed.

Therefore, in the present invention, the product 1 is provided with the lifting pallet 30 together with the structure and the upper carrier 50 in which the stepwise operation is performed vertically and horizontally so that there is no risk of product fall accident. A more stable system can be realized.

According to the product cooling transfer device of the present invention as described above, the existing equipment structure to apply the chain and sprocket that the risk of falling of the product in the transfer existing, as well as to remove only the conventional target of conveying the product to be cooled The structure is improved so that pallets loaded with unit products can be moved up and down together with the product in a continuous stacking system, and ascending and transverse movements are carried out by assembly devices such as multiple cylinders and transfer clamps at the upper and lower turning points. By implementing an automated system that adopts the structure of the upper carrier that holds and transports the product, it is possible to prevent the gradual deviation of the loading position of the product, which may occur during the repeated loading and transportation of the product, as in the conventional case. Accurate and stable product transport performance and high cooling efficiency This can be exerted, and thus there is an effect that the productivity can be remarkably improved.
