Description

DETAILED DESCRIPTION OF THE INVENTION A conventionally known multi-level container loading device has a first
As shown on the drawing plane, multiple rows of containers are stacked in a container hold and are stored in parallel on the same plane at the height of the boundary between the upper and lower stages. Container 01,0
The four corners of the bottom surface of 1, 01... are placed and supported on the protruding arms of a T-shaped corner support metal fitting 03 in an extended position.

The corner support hardware 03 is pivotally supported at its center by a shaft 03' on a hold structural member so as to be rotatable between an extended position and a retracted position in a horizontal plane, and a control arm 04 is provided in a protruding manner. The tip of the arm 04 is latched to a wire loop W wrapped around the inner periphery of the container hold. 017 is a fluid cylinder interposed in the wire loop W for moving the wire loop W in clockwise and counterclockwise directions.

Therefore, if the fluid cylinder 017 is driven to move the wire loop W in the direction of the arrow, each corner support hardware 03 will rotate counterclockwise, and the protruding arm of each corner support hardware 03 will touch the bottom plate of the container 01. It is designed so that it can be rotated out of the four corner positions and into the storage position. Therefore, the container 01 below the loading device can be lifted upward, and the container 01 above the loading device can be lifted downward.

However, in such a loading device, when even one container 01 among the parallel container hold frame structures is in a stowed state, the corner support hardware 03 that supports that container 01 is locked. As a result, all of the other corner support metal fittings 03 are also unrotatable, so there is a drawback that lower multi-tiered containers in other hold frame structures cannot be lifted or unloaded.

The present invention was proposed in view of the above circumstances, and it is possible to safely and reliably lift and unload lower containers in other hold frame structures even when upper containers are loaded in some hold frame structures. The purpose of the present invention is to provide a container loading device for multi-tiered stacking, which has a simple structure and is inexpensive, and which can hold containers at one end so that the free end can rotate between an extended position and a storage position. A plurality of sets of corner support hardware on the same plane, each consisting of a set of four pieces, are pivoted to the four corner positions of the frame structure, and each center part is pivoted to the steel wall side of the hold, and both ends are opposed to each other via links. a plurality of corner support hardware turning levers pivotally connected to control arms projecting from each of the corner support hardware; a plurality of balancing levers each having one end pivotally connected to one end of the corner support hardware turning lever; It is characterized by comprising a plurality of links that pivotally connect the center portion of each balancing lever to the other end of the adjacent balancing lever, and a fluid cylinder that provides a stroke to the plurality of links.

An embodiment of the present invention will be explained with reference to the drawings.

Next, as shown in the enlarged views of FIGS. 4 and 5, the corner support hardware 3 moves from the storage position shown by the chain line to the extended position shown by the solid line without being obstructed by the cell guide 2.
The hatched part a of the cell guide 2 has been cut out so that it can be rotated by 45 degrees, and on the corner support hardware 3 at the extended position shown by the solid line,
When the four corners of the bottom of the container 1 are placed and supported, the corner support hardware 3 is provided with a hatching that abuts against the container 1 as a means to prevent the corner support hardware 3 from rotating to the storage position shown by the chain line. The chamfering is done so that part F is lower than other parts by h.

In such a device, when the link 16 is moved in the direction of the left arrow by the fluid cylinder 17 as shown in FIG. 6, the L-shaped lever 14, the link 12,
Since the links 10 and 11 each move in the direction of the arrow, each corner support metal fitting 3 can rotate to the extended position as shown by the arrow, and can stop when it hits the stopper 6.

In this way, after all the corner supporting hardware 3 are simultaneously linked and rotated to the overhanging position, the container 1b is moved along the cell guide 2 by a crane (not shown) into the holding frame structure, as shown by the chain line. The four corners of the bottom surface can be placed and supported on four corner support hardware 3.

At this time, as shown in FIGS. 4 and 5, the bottom corner of the container is seated against the contact surface F recessed in the corresponding corner support metal fitting 3, so that in the unlikely event that the container is inadvertently Even if the cylinder 17 is operated, the corner support hardware 3 is locked by its vertical surface f hitting the vertical surface of the container 1b placed and supported, so it will not rotate to the storage position (dashed line). Therefore, there is no risk of an accident of the upper stacked container 1b falling.

In addition, in order to rotate the corner support hardware 3 from the extended position to the retracted position, as shown in FIG. 7, operate the fluid cylinder 17 and move the links 16, 16 to the right as shown by the arrow. do.

Then, L-shaped lever 14, link 12, balancing lever 8, turning lever 7, link 1
0, 11, 13, the control arms 4 move in the directions of the arrows, and the corner support hardware 3 rotates to the retracted position shown by the solid line.

At that time, as shown by the chain line, the lower stacked container 1b
Assuming that there is a corner support hardware 3 on which is placed and supported, the corner support hardware 3 is locked in the extended position by contacting the container 1b with the abutment surface f, as described above with reference to FIG. It cannot be rotated to the storage position. Therefore, the turning lever 7, which is connected to these four locked corner supports 3 by links 10, 11,
The position of 7 also remains unchanged.

As a result, link 13, as shown by the arrow,
When moved, the balancing lever 8 moves to the pivot point 10'
By rotating clockwise around the , and moving the next link 13 in the direction of the arrow, all the corner support hardware 3 on which the container is not loaded are moved from the extended position via the balancing lever 8, links 13, 13, etc. It can be brought to the storage position.

In this way, the link 13 moves the adjacent link 13 through the rotation of the balancing lever 8, thereby moving the link 13 to the next adjacent link 1 regardless of the presence or absence of the corner support member 3 that supports the container.
I can convey movement to 3.

As described through the embodiments described above, according to the present invention, a balancing lever is pivotally connected to one end of the turning lever that moves each corner support hardware to the extended position and the retracted position, respectively, and the adjacent By applying push and pull forces to the balancing lever in conjunction with each other, even if there is a hold frame structure with containers stacked on the upper level, it is possible to freely lift and unload containers in other hold frame structures. The present invention is industrially extremely useful because it provides this kind of multi-tiered container loading device that is safe, reliable, simple in structure, and inexpensive.
