Abstract

PURPOSE:To enable the title device to be moved up and down vertically with a small driving capacity by arranging middle and upper frames which can move sidewise freely and make interlocking motion with each other on the lower frame, which can move up and down freely, in a lift for shelf loading and further a receiving member which can move up and down vertically and freely on the upper frame and also providing drive means for each movement, in the device in the title for long goods. CONSTITUTION:The lower frame 3 of a lift for shelf loading is moved up and down to a prescribed shelf position by wire ropes 27, 28. When a drive device 4 for sideways movement is rotated normally, a middle frame 5 is moved sidewise toward the inside of shelf and an upper frame 6 is moved sidewise in the same direction being interlocked thereto by a twice moving amount as much as that of the middle frame 5. When the rotation is reversed, it is moved sidewise reversely. When a drive device 8 for moving a cam member sidewise is rotated normally/reversely, a load receiving member 7 is moved up and down vertically by the cooperative work of cam members 9 and cam grooves 10. Therefore, the device can be moved up and down vertically by means of a drive device with a small capacity by the combination of these operations.

As disclosed in Publication No. 65806, a rail and a cargo receiving part are provided on a shelf installed on at least one side of a fixed frame having a rail, and a traveling body that moves forward and backward on the rail of the fixed frame and shelf, A load-receiving elevating body that is raised and lowered by the rotation of a large number of links is provided, a traveling drive device that moves the traveling body largely forward and backward in at least one side is fixed to the fixed frame, and the elevating drive device moves the many links. A shelving transfer device configured to rotate is known.

[Problem to be solved by the invention]

However, in the case of the conventional shelving transfer device, the cargo receiving elevating body is moved up and down in an arc shape by the rotation of the link, so that the cargo can be loaded onto the cargo receiving elevating body! When the loaded baggage is moved up and down by the rotation of the link, the baggage moves up and down while being deviated in the lateral direction, making it difficult to accurately lower the baggage to a predetermined position within the shelf.

In addition, when moving the load receiving lifting body up and down by rotating the link, the inclination angle of the link changes, and when the inclination angle of the link is small, a large drive torque is required. The problem is that you need it.

The object of the present invention is to provide a shelf loading transfer device that can vertically lift and lower long items to be transferred using a small-capacity lifting drive device. .
