Description

[Detailed explanation of the idea] The present invention relates to an apparatus for automatically stacking members in sequence.

For example, when a press factory presses members such as plates into a predetermined shape one after another, stacks them one after another, and transports them to an assembly factory for the next process, conventionally the pressed members are hung one after another on the frame of a loading pallet. However, in this case, inclusions are manually placed between each member and the members are stacked one after another.

In this way, manual stacking work in which inclusions are inserted requires a considerable amount of time when loading or unloading members, is inefficient, and may be dangerous in some cases.

The present invention was developed in view of the above, and uses the weight of the plate-like members to maintain the vertical positional relationship and pivot them to multiple supporting columns facing each other so that the members can be stacked automatically. To provide a component stacking device in which a lower supporting claw of a supported supporting claw is rotated, thereby operating an upper supporting claw, and the upper supporting claw can receive the next member. It is.

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

Reference numerals 1 denote pillars fixed perpendicularly to the four corners of the base 2, and the pillars 1 are opposed to each other along the outer shape of the pressed plate member 3, which is the member to be placed. It is located.

The column 1 has a U-shaped cross section, and a plurality of horizontal pins 4 are attached to the inner side of the column so as to be rotatable in the vertical direction at predetermined intervals, passing through the left and right side plates, and each pin 4 has a support claw 5. Each is fixedly attached approximately at the center.

Therefore, the support claw 5 is set so that the foot part 7 is slightly heavier than the head part 6, and in an unloaded state, it is slightly inclined toward the inner side 8 of the opposing support column with the pin 4 as the axis, as shown in FIG. and
The shape of the tip of the head 6 that receives the plate-like member 3 is made to match the outer peripheral shape of the plate-like member 3.

In this embodiment, since the outer edge shape of the plate-like member 3 is formed into a cross-sectional shape, the head tip shape is formed into a stepped notch 9 in accordance with this.

Next, the operation of the support claw will be explained.

First, the case of stacking the pressed plate-like members 3 will be explained in the third section.
The diagram will be explained.

The figure shows three support claws, the lowest support claw 5a is in a state where it has finished supporting the plate-like member 3, and the upper support claw 5b is in a standby state waiting for the plate-like member to be carried. The uppermost support claw 5c is in an unloaded state.

In the state where the support claws 5a support the plate-like member 3, the support claws 5a
The foot portion 7 of the support claw 5b is engaged with the foot portion 7 of the support claw 5b, and the tip of the head 6 of the support claw 5b is extended from the support 1 and is in a waiting state.

Next, the fed plate member 3 descends and its outer edge abuts the stepped notch 9 of the support claw 5b and presses down the head 6, causing the claw 5
In b, the head 6 is rotated to a substantially horizontal position as shown by the broken line.

As the support claw 5b rotates, its foot portion 7 collides with the bottom of the foot portion 7 of the support claw 5c one step above, causing the support claw 5c to rotate to the standby state shown by the broken line.

Further, the fed plate-like member is supported by the support claws 5c as described above.

Thereafter, the stacks are stacked from the bottom to the top in the same manner.

The plate-like member 3 is supported by support claws 5 extending from four sides, the outer edge of which has a cross-sectional shape of an L-shaped cross section, while the tip of the head of the support claw 5 has a stepped portion corresponding to this shape. Therefore, the weight of the plate-like member 3 can be well supported by the stepped portions of the support claws, and the four support claws can be stopped while supporting the weight of the plate-like member.

As a means for restricting further rotation of the support claw 5 while supporting the plate-shaped member, the shape of the end of the support claw 5 may be matched to the shape of the outer edge of the plate-shaped member as described above. For example, the over-rotation of the pin 4 to which the pawl is attached may be prevented by a stopper, or the pawl may be directly placed against the stopper.

Next, the case of taking out the stacked plate-like members will be explained with reference to FIG. 4. In the figure, the supporting claw 5c' is in a state where the plate-like member has already been taken out, and the foot portions of the supporting claw 5c' and the lower supporting claw 5b' are mutually disposed. engaged.

When the plate member 3 supported by the support claw 5b' is taken out upward, the claw rotates counterclockwise in the figure to the state shown by the broken line due to its own weight, and at the same time, the support claw 5c' moves to the state shown by the broken line. It is returned to the loaded state and the plate member is easily removed.

In this way, the plate-like members are sequentially taken out downward.

As explained above, the present invention is configured so that the supporting claws are operated by using the weight of the member and the gravity of the supporting claws.
The structure is extremely simple, and parts can be separated and stacked automatically without intervening objects as in the conventional method, making loading and unloading operations easy and quick, and is highly safe.

Claims (1)

[Scope of utility model registration request] A plurality of columns are vertically erected facing each other, and the center is pivotally supported by a pin attached horizontally to each of the columns, and the pin is attached to the top of the column rather than the head on which the member to be placed is placed. It consists of a plurality of supporting claws arranged vertically at required intervals, with the legs on the opposite side of the center being slightly heavier and tilted, and a restraining means for regulating the amount of rotation of the supporting claws, and the upper and lower positions The head of the lower supporting claw in the relationship is rotated to a nearly horizontal position by the weight of the member to be placed, and the foot of the lower claw collides with the foot of the upper claw, causing the upper claw to collide with the foot of the upper claw. A member stacking device characterized in that the supporting claws are rotated so that the head of the upper supporting claw can support the next member to be placed.
