BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work storage shelf, and more particularly to a work storage shelf for stacking and placing a plurality of works conveyed by an automatic carry-in / out device or the like.

[0002]

2. Description of the Related Art Generally, in an automatic loading / unloading device, a work such as woodwork parts such as furniture is supplied to a predetermined woodworking machine or the like, and a work which has been processed by the woodworking machine or the like is carried out. When carrying in and out such a work, the work is stored and mounted at a predetermined position.

[0003] Conventionally, such works have been simply stacked and placed. However, if the upper and lower surfaces of the work are formed in a flat plate shape, there is no problem even if only the means for stacking and mounting is used. For example, as shown in FIG.
If the work 1 having a curved upper surface is stacked and placed in a plurality of stages, the work 1 may lose its balance and collapse when it is stored or taken out, resulting in damage to the work 1. Work 1 that collapsed
However, there is a problem that the worker is injured when hit by the worker, which is dangerous.

Therefore, conventionally, as shown in FIG.
When the works 1 are stacked and mounted, a mounting jig 2 having, for example, a U-shaped cross section is interposed between the works 1. That is, the mounting jig 2 is installed above the work 1 so as to straddle the work 1, and the next work 1 is mounted on the upper surface of the mounting jig 2. The mounting jig 2 of the next stage is mounted on the upper surface of the jig 2, and this is sequentially repeated so that a plurality of works 1 are stacked and mounted.

[0005]

However, in the above-mentioned conventional work storing means, one mounting jig 2 is separately required for each work 1, and the mounting jig 2 is mounted every time the work 1 is mounted. Since the work jig 2 must be placed, the work of placing the work 1 is extremely troublesome, and there is a problem that automation of the work of loading the work 1 cannot be properly handled. In addition, when the work 1 is not mounted, the mounting jig 2 is not required, so that a storage space for the mounting jig 2 is required, and the work space is wasted. ing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned point, and it is possible to easily stack and place works without using a separate jig or the like, and to appropriately cope with automation of a loading operation. It is an object of the present invention to provide a work storage shelf that can be used.

[0007]

In order to achieve the above object, a work storage shelf according to the present invention is a work storage shelf for stacking a plurality of works conveyed by an automatic loading / unloading device or the like. A pair of side plates having recesses formed on opposing surfaces are erected on both sides of the base, and the recesses of each side plate are rotatable around a rotation axis and housed inside the recess by an urging spring. A plurality of stopper levers urged in the direction to be arranged are arranged vertically close to each other in parallel, and a mounting piece having a flat upper surface is formed at an inner end of the stopper lever. At the same time, on the outer end of the stopper lever, the lower surface side is the surface to be pushed up, and the upper end portion pushes up the surface to be pushed up of the upper stopper lever to push the stopper lever against the urging force of the urging spring. Push-up part that is a push-up part that rotates slightly It is characterized in that the formation of the.

[0008]

According to the present invention, by lowering the work from between the side plates, both ends of the work are brought into contact with the mounting surface of the lowermost stopper lever. Then, the stopper lever is rotated against the urging force of the urging spring, and the work is mounted on the mounting surface of the stopper lever. On the other hand, by the rotation of the lowermost stopper lever, the push-up portion of the stopper lever is moved by two.
The push-up surface of the step is pushed up, whereby
The stopper lever of the step is rotated against the urging force of the urging spring, and a part of the mounting piece is projected from the concave portion. In this manner, the work is sequentially moved from the stopper lever of the lower step. By mounting on the mounting surface, the mounting piece of the stopper lever on the next upper stage of the stopper lever on which the work is mounted will protrude from the concave portion. They can be stacked one after another and stored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIGS. 1 and 2 show an embodiment of a work storage shelf according to the present invention. A pair of side plates 4 and 4 are provided upright on both sides of a flat base 3. A concave portion 5 extending in the up-down direction is formed on the surface of each side plate 4 facing each other. Also, a plurality of stopper levers 6, 6... Are arranged vertically adjacently in the recess 5 of each side plate 4, and the stopper levers 6 of each side plate 4 are opposed to each other. It has been done. Each of the stopper levers 6 is rotatable up and down around a substantially horizontal rotation shaft 7.
Is the side plate 4 in the state of being turned rightmost in FIG.
Is accommodated inside the concave portion 5 of FIG.

A mounting piece 8 is formed at the inner end of the stopper lever 6, and the upper surface of the mounting piece 8 is a flat mounting surface 9. A push-up piece 10 is formed at the outer end of the stopper lever 6, and the lower surface of the push-up piece 10 serves as a surface to be pushed-up 11. The upper portion is a push-up portion 12 that pushes up the pushed-up surface 11 of the upper stopper lever 6 to slightly rotate the stopper lever 6. Further, an urging spring 1 is provided around the rotation shaft 7.
One end of the biasing spring 13 is connected to a holding pin 14 attached to the side surface of the recess 5, and the other end of the biasing spring 13 is connected to the stopper lever 6. It is connected to the. Thus, the stopper lever 6 is always biased in a direction in which the stopper lever 6 is housed inside the recess 5.

The lowermost stopper lever 6 is held on the inner surface of the concave portion 5 corresponding to the lowermost stopper lever 6 at a position where a part of the mounting piece 8 projects from the concave portion 5. Are formed.

Further, on the lower surface side of the base 3, wheels 1
6 are attached.

Next, the operation of this embodiment will be described.

In this embodiment, the workpiece 1 conveyed from a predetermined processing apparatus by a loading / unloading device (not shown) is lowered from above between the side plates 4 so that the lowermost stopper lever is moved by stopper pins 15. Since a part of the mounting piece 8 protrudes from the concave portion 5, both ends of the work 1 abut against the mounting surface 9 of the lowermost stopper lever 6, and when the work 1 is further lowered, the work 1 Due to its own weight, the stopper lever 6 is rotated leftward in FIG. 2 against the urging force of the urging spring 13, and the work 1 is mounted on the mounting surface 9 of the stopper lever 6.

On the other hand, the rotation of the lowermost stopper lever 6 causes the push-up portion 12 of the stopper lever 6 to push up the second-stage pushed-up surface 11 to thereby raise the second-stage pushed-up surface 11. The stopper lever 6 is rotated against the urging force of the urging spring 13, and a part of the mounting piece 8 projects from the recess 5.

Then, by lowering the next work 1 between the side plates 4, both ends of the work 1 are brought into contact with the mounting surface 9 of the second-stage stopper lever 6, and the stopper of the work 1 is moved by its own weight. When the lever 6 is further rotated, the work 1 is moved to 2
It is mounted on the mounting surface 9 of the stopper lever 6 of the step. In this case, similarly to the above operation, the second-stage stopper lever 6
The push-up portion 12 pushes up the pushed-up surface 11 of the third-stage stopper lever 6 and rotates the third-stage stopper lever 6 so that a portion of the mounting piece 8 projects. .

As described above, the work 1 is sequentially placed on the mounting surface 9 from the lower stopper lever 6 so that the mounting piece of the stopper lever 6 on the next upper stage of the stopper lever 6 on which the work 1 is mounted is placed. Since the projections 8 protrude from the recesses 5, the workpieces 1 can be sequentially stacked and stored only by lowering the workpieces 1 from above.

When the work 1 is taken out of the storage shelf in which the work 1 is stored in this manner, the work 1 is sequentially taken upward from the work 1 placed on the placement surface 9 of the stopper lever 6 at the uppermost stage. The stopper lever 6 from which the work 1 has been taken out is pushed up by its urging force of the urging spring
Is rotated until it comes into contact with the push-up portion 12 of the lower stopper lever 6. Then, by taking out the next lower work 1, the stopper lever 6 rotates, and accordingly, the push-up portion 12 holding the upper stopper lever 6 is rotated downward. The upper stopper lever 6 is completely retracted inside the recess 5 and does not hinder the removal of the work 1.

Therefore, in this embodiment, the side plate 4
By simply inserting the work 1 from above, the work 1 can be securely held by the stopper lever 6, and further, with the work 1 placed on the stopper lever 6,
Since the mounting piece 8 of the stopper lever 6 at the next upper stage projects from the recess 5, the workpieces 1 can be sequentially mounted on the stopper lever 6 without providing a special lever rotating mechanism. As a result, it is possible to appropriately cope with the automation of the laminating operation, and it is not necessary to use a jig or the like, so that the working space can be saved.

The present invention is not limited to the above embodiment, but can be variously modified as needed.

[0022]

[Effect of the Invention] As described above, the work storage shelf according to the present invention requires only inserting a work from above between the side plates.
The work piece can be securely held by the stopper lever, and when the work piece is placed on the stopper lever, the mounting piece of the next upper stopper lever will protrude from the recess, so that a special lever rotation The work can be sequentially placed on the stopper lever without providing a mechanism.
