Japanese Patent No. 42227850

  However, in the above prior art, the transport surface of the oven-connected conveyor is set higher than the floor surface, whereas the top plate mounting shelf at the bottom of the top rack is intended to increase the loading capacity. Since it is set at a position close to the floor surface, it is necessary to place the top plate mounting shelf at the bottom of the top plate rack above the conveying surface of the oven connection conveyor in the rack unloader. There were problems that had to be solved, such as the need to move the rack.

  In view of the problem of requiring a means for moving the top rack above the floor surface based on the above-described conventional technology, the present invention has a pair of an entrance on the rear surface, an exit on the front surface, and opposed to each other. A rack unloader provided at the same distance as the vertical spacing of the top plate mounting shelf in the top rack, and a rear surface side of the rack unloader. A pusher that pushes the top plate accommodated in the top rack into the rack unloader, and a conveyor that is disposed on the front surface of the rack unloader and carries the top plate transferred to the rack unloader. The number of support pieces in the vertical vertical section of the lifting conveyor is set so that there are more than the number of top plates to be transferred above the transport surface of the carry-out conveyor. It is installed in a hanging state outside the front surface of the machine, and can be swung up and down around the upper end, and can be horizontally placed between a pair of lifting conveyors in an upwardly swung state. After the plates are transferred, the rack unloader lifts all the top plates up to the top of the carry-out conveyor without disturbing the carry-out conveyor, and then swings the carry-out conveyor upward to bring the top plate in the carry-in state. The above problem is solved by making it possible to cope with the lowest level of the top plate mounting shelf in the plate rack at a position lower than the transport surface of the carry-out conveyor and the oven connection conveyor.

In short, the present invention has a pair of elevating conveyors having an inlet on the rear surface, an outlet on the front surface and opposedly arranged inside, and a plurality of support pieces are mounted on each elevating conveyor, A rack unloader provided at the same interval as the vertical interval of the shelf, a pusher that is disposed on the rear side of the rack unloader and pushes the top plate accommodated in the top rack into the rack unloader, and the rack unloader Since it has a conveyor that is disposed on the front surface and carries the top plate transferred to the rack unloader, if the top plate rack is arranged at a predetermined position between the rack unloader and the pusher, The top plate accommodated in the top plate rack can be transferred to the rack unloader by the pusher, and if the top plate is lowered by the rack unloader, the top plate is placed on the carry-out conveyor. Since it is possible transfer to be carried out one by one, can be a top plate of the housing conditions in the top plate rack regardless of the operator automatically give away one by one send out to the next step.
In general, the lowermost level of the top plate mounting shelf in the top table rack in the carry-in state is lower than the transport surface of the carry-out conveyor and the oven connection conveyor, but the number of support pieces in the opposed vertical part of the lift conveyor Is set so that there are more than the number of top plates to be transferred above the transport surface of the carry-out conveyor. Even when transferred to the rack unloader, all the top plates can be raised above the transport surface of the carry-out conveyor by the rack unloader, and the carry-out conveyor is installed in a hanging state outside the front surface of the rack unloader. Since it can swing up and down around the upper end and can be placed horizontally between a pair of lifting conveyors in an upward swinging state, it can be carried out after the top plate is lifted by a rack unloader. If caused to upwardly swing the Nbeya, since discharge conveyor during rising process does not interfere, it is possible to dispense with means for moving the top board rack above the floor surface.

  The top rack is divided into a plurality of inner rows in the longitudinal direction to form a plurality of storage rows, a top plate mounting shelf is formed in each storage row, and between the rack unloader and the pusher, A top plate rack feeding device is provided. The top plate rack feeding device includes a loading / unloading port provided on both sides, a movable body provided in a reciprocating manner at an upper portion, and a top rack provided at a lower portion of the movable body.
