The carry-out device 5 has the same structure as the carry-in devices 4A and 4B, and has a movable base that supports the movable conveyor 15, a base that supports the movable base, and a movable conveyor 15 that is vertically driven with respect to the movable base. The up-and-down driving means and the horizontal driving means for driving the movable table in the horizontal direction with respect to the base are the movable table 1 for supporting the movable conveyor 13 of the carry-in devices 4A and 4B.
7, a base 16 that supports the movable base 17, a vertical drive unit 23 that drives the movable conveyor 13 in the vertical direction with respect to the movable base 17, and a horizontal drive that drives the movable base 17 in the horizontal direction with respect to the base 16. Since it is the same as the driving means 24, illustration and description thereof will be omitted. Of course, this carry-out device 5
Also, like the carry-in devices 4A and 4B, the carriages 7 can be omitted by disposing them for each of the storage conveyor units 1A and 1B.

A sorting conveyor 8 for loading, a loading device 4A,
The fixed conveyor 12 and the movable conveyor 13 of 4B, the movable conveyor 15 and the fixed conveyor 14 of the unloading device 5, and the merging conveyor 11 for unloading can be configured by a belt conveyor or a roller conveyor driven by a motor. Further, although the gravity roller conveyor is used as the storage conveyor of the storage conveyor units 1A and 1B, the entire length is not composed only of the gravity roller conveyor, but a part thereof, for example, a certain area on the carry-in end side is driven by a motor. It is also possible to use a roller conveyor, a belt conveyor, or the like, which is configured so that the load W to be carried in is forcibly accelerated and fed downward to the slope.

The load W carried by the loading sorting conveyor 8 is controlled by the sorting means 9 to bring in the loading device 4A.
Alternatively, it is sent to the fixed conveyor 12 of 4B. The load W is sent from the fixed conveyor 12 to the carry-in end of the movable conveyor 13, and by this movable conveyor 13, one gravity of the gravity roller conveyor 2 of the storage conveyor unit 1A or 1B to which the carry-out end of the movable conveyor 13 is connected. The load W is sent to the carry-in end (upper end of the slope) of the roller conveyor 2. On the gravity roller conveyor 2, the load W slides downward due to gravity, and stops by coming into contact with the stopper 3 at the carry-out end or the rear end of the line of the load W received by the stopper 3.

When one gravity roller conveyor 2 is filled with the load W as described above, the carry-in devices 4A, 4
As described above, the movable conveyor 13 of B can be changed in angle vertically and horizontally, and can be connected to the carry-in end of another gravity roller conveyor 2 which is empty or not full to change the carry-in destination of the load W.

When unloading the load W stored in the storage conveyor unit 1A or 1B, the carriage 7 is stopped so that the unloading device 5 is connected to the storage conveyor unit 1A or 1B, and the unloading device 5 is stopped. Movable conveyor 15
As described above, the angle is changed up, down, left, and right to connect to the carry-out end of the gravity roller conveyor 2 to be carried out, and the stopper 3 is opened to move the load W on the gravity roller conveyor 2 from the top. It is slidably transferred onto the conveyor 15. The load W transferred onto the movable conveyor 15
Is carried out onto the carrying-out merging conveyor 11 via the movable conveyor 15 and the fixed conveyor 14, and is carried to the target location by the merging conveyor 11. When one gravity roller conveyor 2 is emptied, the movable conveyor 15 is angled again vertically and horizontally as described above, and the load W
The load W can be continuously carried out by connecting to another gravity roller conveyor 2 in which is stored.

It should be noted that only one of the carry-in devices 4A, 4B and the carry-out device 5 uses a movable conveyor whose angle can be changed vertically and horizontally, and the other device is a movable conveyor which can only horizontally swing. The sorting conveyor 8 for loading or the merging conveyor 11 for unloading connected to each is arranged for each gravity roller conveyor 2 of each stage, or a movable conveyor capable of only vertical swing and a sorting conveyor 8 for loading connected thereto It is also possible to arrange the carry-out merging conveyor 11 for each row of gravity roller conveyors 2.

Further, in the apparatus of the present invention, the movable conveyors 13 and 15 can basically swing up and down, and can be selectively connected to a plurality of upper and lower storage conveyors, that is, the gravity roller conveyor 2. When the storage conveyors (gravity roller conveyors 2) are arranged in a plurality of upper and lower stages in a plurality of rows in each stage, the movable conveyors 13 and 15 are arranged in each row or the unloading device is provided. In this case, the movable conveyor 15 is configured to be movable laterally along the parallel direction of the storage conveyor (gravity roller conveyor 2) so that it can be selectively connected to the storage conveyor of any row. Good. Specifically, in the carry-out device 5 shown in FIG.
Is installed on the dolly 7, and the conveyor unit 1 for each storage 1 is moved by the lateral movement of the dolly 7 and the vertical swing of the movable conveyor 15.
The movable conveyors 15 can be connected to the storage conveyors (gravity roller conveyors 2) of arbitrary rows in A and 1B.

[0023]

According to the carrying-in or carrying-out apparatus of the present invention which can be carried out as described above, the angles can be changed vertically with respect to the storage conveyors (2) arranged in a plurality of upper and lower stages. One movable conveyor (13,15) connected to it allows the load to be loaded into or unloaded from any one of the storage conveyors of each tier. Therefore, it is only necessary to connect the load conveyor line or the load conveyor line to the movable conveyor in contrast to the upper and lower storage conveyors. It is not necessary to do so, and it is possible to significantly reduce the cost of the entire equipment.

According to the second aspect of the present invention, in the case where the storage conveyors are arranged in a plurality of rows in a plurality of upper and lower rows, one movable conveyor that can be vertically swung is moved laterally to make it arbitrary. Since a movable conveyor can be connected to the storage conveyor at any stage of the row, a significant cost reduction is achieved compared to the case where the movable conveyor must be provided for each row storage conveyor. be able to.

According to the structure of claim 3, 1
Even if two movable conveyors do not move horizontally in parallel to the storage conveyors, one movable conveyor can be selectively connected to the storage conveyors in each row and multiple rows at least in the upper and lower stages, further reducing the cost. Can be achieved. Further, according to the configuration of claim 4, when the storage conveyors (2) are arranged in three stages, the maximum inclination angle of the movable conveyors (13, 15) becomes small, and the storage conveyors of each stage are reduced. It is possible to reliably carry in or carry out without slipping the load.

Further, when the up-and-down driving means (23) when the storage conveyors (2) are arranged in the upper and lower three stages as described above is constructed according to the fifth aspect, it is movable while using the cylinder unit. The conveyors (13, 15) can be reliably positioned in the upper and lower three positions, and control can be performed easily and easily.
Further, by configuring the horizontal driving means (24) according to the sixth aspect when the storage conveyors (2) are arranged in three horizontal rows, the movable conveyors (13, 15) can be moved while using the cylinder unit. Positioning can be reliably performed in three horizontal positions, and control can be performed easily and easily.
