On the other hand, the above-mentioned device body 3 is provided between the furnace 1 and the storage 4, and faces both the charging port 2 of the furnace 1 and the outlet 6 of the storage 4. Is provided outside the take-out port 6 and is provided with a conveyor 20 that is continuous with the carry-out conveyor 15 and a conveyor 21 that is provided between the conveyor 20 and the furnace 1 and is continuous with the conveyor 20. Has been.

Further, adjacent to the conveyor 20, a tray t having a size capable of mounting a plurality of (two in the illustrated example) works w ...
Tray storage unit 22 for storing a large number of stacks vertically
In the tray storage portion 22, a pusher (first pusher) 23 for supporting the stacked trays t ... From below and sequentially pushing up the trays t.

Also, adjacent to the tray storage section 22, the tray storage section 22
The trays t stacked at the top of the inside of the tray 20 are provided with pushers 24 for pushing them forward (on the side of the conveyor 20) and placing them on the conveyor 20. A pusher (second pusher) 25 for pushing out the tray t placed on the front side (furnace 1 side) is provided.

Explaining how to use the charging device having the above-described configuration, first, the works w are loaded one by one into the storage 4 from the carry-in port 5, and the works w are transported to a desired position on the rack 7 by the transport device 9. By going, a large number of works w are stored.

Then, the stored work w is sent to the apparatus main body 3,
The apparatus main body 3 is used to load the furnace 1. First, the pusher 23 provided in the tray housing 22 is operated to stack a large number of trays t.
The position of the uppermost tray t is matched with the height of the conveyor 20, and the uppermost tray t is pushed out by the pusher 24 and placed on the conveyor 20. Then, the work w stored in the desired position of the rack 7 is transferred onto the conveyor 15 by the transfer device 9, the pusher 16 is operated to push out the work w, and the tray t already placed on the conveyor 20 is transferred. Put it on top. After sending the uppermost tray t from the tray storage section 22 onto the conveyor 20,
