Next, to explain the shipping method, the container 4 to be shipped
While driving the carousel 2 so as not to call the tray of the carousel 2 loaded with 0 to the loading/unloading position adjacent to the container transfer device 1, the lifting platform 4 of the container transfer device 1 is moved along the imaginary line in FIG. The drive motor 7 rotates the chain 5 and moves it up and down until the hook 24 of the pull-in and push-out tool 17 faces the end surface 41 at a position below the locked 842 of the container 40 to be delivered. At this time, the turntable 8 is oriented so that the stopper 142 comes into contact with one side 4a of the lifting platform 4, as shown in FIG. It matches the container transfer direction at the shipping position. The container pulling and pushing tool 17 faces the container loading/unloading position.

In this state, the movable base 15 is moved by the motor 19 to the check 2.
25 is rotated and moved along the guide rail 16 to the forward limit position. Before the movable base 15 reaches the forward limit position, the retraction and push-out shell 17 is moved as shown by the imaginary line in FIG. Both pushers 25a, 25b abut against the end surface 41 of the container 40 below the locked portion 42, and only the movable platform 15 moves to the forward limit position while compressing the recompression coil springs 31a, 31b. Next, when the lifting platform 4 is raised to the loading/unloading level shown by the solid line in FIG. 42 from below. Thereafter, by rotating the chino 25 in the reverse direction and moving the movable base 15 backward, the hook 24 of the pull-in/push-out tool 17 and both swivels are removed, as shown in FIG.
25a, 25b protrude to the protrusion limit position, the tip upwardly protruding portion 24a of the hook 24 engages with the inner surface of the locked portion 42, and the container 4 on the tray of the rotating shelf 2 is
0 onto the container supporting guide rail 54 of the turntable 8 located at a slightly higher level.

At this time, the container 40 is guided by a pair of left and right side guide rails 65.

When the movable base 15 reaches the backward limit position shown in FIG.
The container 40 has been pulled in to a substantially central position on the turntable δ, and in this state, the turntable 8 is rotated by the motor 11, and the chino 16 is rotated to rotate the vertical axis 100.
The stopper 14b is rotated 180 degrees around the lifting platform 4.
It is stopped in a state where it comes into contact with the other side surface 4b. On the other hand, the first
As shown by the imaginary line in the figure, a container transport vehicle 46 is placed on standby on the opposite side of the container transfer device 1 from the side where the rotating shelf 2 is located, so that the lifting platform 4 is driven up and down by the chino 5. , the turntable 8 of the container transfer device 1 is mounted on the container support stand 44 of the container carrier 46.
are arranged in parallel at approximately the same level. After this, the movable base 15 at the backward limit position is moved forward again by the chino 25, and the pusher 2 of the pull-in and push-out tool 17 moves forward together.
Container 40 on turntable 8 by 5a and 25b
is pushed out to the side opposite to the side where the rotating shelf 2 is located, and transferred from the turntable 8''2 onto the container support stand 44 of the container carrier 45. At this time, the buttons 25a, 25
b and the hook 24 are connected to the spring 5 with respect to the support member 27.
The container 40 is pushed out while the container 40 is moved to the backward limit position against the forces 1a and 51b.

The container unloading work is completed with the above steps, but conversely, when loading the containers 40 on the container carrier 46''- into the carousel 2, the container transfer device 1 is used in the reverse procedure of the unloading work described in 1. Just shift it. Further, the rotation angle of the turntable 8 may be set according to the standby position of the container 1 transporting cart 46, and is not limited to 180° as in the embodiment. Furthermore, a conveyor for transporting containers can be used instead of the container I transporting trolley 45.

The container transfer device of the present invention can be implemented and used as in the above embodiment, and includes a turntable that can be raised and lowered.
Second, a movable body capable of reciprocating in the diametrical direction is provided, a container pulling and pushing tool is provided on the movable body, and a container guiding means (implemented) for guiding the container drawn onto the turntable by the container pulling and pushing tool is provided. In the example, since a container supporting guide rail 34 and a side guide rail 55 are provided on the turntable, the conventional transfer device of this type, that is, the pulling and pushing tool is connected to the container pulling and pushing path. The structure is extremely simple and can be implemented at low cost compared to a device that can be moved downward or a device that is provided with a conveyor for conveying a container separately from the pull-in/push tool. In addition, the container that has been pulled in can be pushed out in any direction by the rotation of the turntable by using the pulling and pushing tool used for pulling it in, and as in the embodiment, the container can be pushed out in any direction between the rotating shelf and the transport vehicle. It can be conveniently used as a transfer device.

In particular, as shown in the embodiment, the Mi+ drawing/pushing tool is connected to a retractable hook provided at the end of the container that can be freely engaged with and detached from the engaged part, and in a state that protrudes beyond the hook. It consists of a button shear that comes into contact with the end surface of the container beside the stop, and the hook and the button 2 shear are supported so as to be movable back and forth within a certain range with respect to the movable body, and are attached so as to project forward. When a spring is provided to bias the container, for example, even if there is variation in the position of the container supported on the rotating shelf side in the front and back direction, as in the example,
Alternatively, even if the end surface of the container is inclined as shown in FIG. 7, the hook can be reliably engaged with the locked portion of the container.
