Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention is for accumulating products such as turret punch presses and quadrangular plate-like works cut by a shearing machine. The present invention relates to an integrated device capable of aligning formed works.

(Prior Art) When a plurality of works are loaded on a work table of a work stacking apparatus, the conventional piler and unloader push the works one by one with a pusher to align the works when stacking the works.

(Problems to be Solved by the Invention) By the way, when the conventional work stacking apparatus does not have a lifter, it is very difficult to automatically stack the works in good alignment. Further, when the workpieces are accumulated by an unloader such as a turret punch press, a deviation of several millimeters is inevitably generated, which causes a problem that the workpieces are not aligned properly.

[Structure of the Invention] (Means for Solving the Problems) In view of the above-mentioned conventional problems, the present invention relates to a work table oscillatably supported on a base through an elastic device. A vibration motor for imparting vibration is mounted on the work table, and each corner of the work is horizontally placed on an X-shaped guide bar arranged above the rectangular plate-like work accumulated on the work table. A work clamp having an L-shape that can be pressed from one direction is installed, and one corner of the pair of work clamps facing each other by pressing each corner of the work from the horizontal direction is appropriately used. It is urged so that it can move in any direction.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Referring to FIG. 1, the work stacking device 1 is placed on the rear side of a turret punch press, a shearing machine, or the like, for example, and is a product in which a hole is formed in the work W or a square work W that has been cut. (Hereinafter, collectively referred to as a work).

An air spring 5 as an elastic device is provided on the base 3 of the work stacking device 1. A work table 7 is placed on the air spring 5. A plurality of vibration motors 11 are attached to the lower portion of the work table 7 via brackets 9.

On both sides of the work table 7, there are mounted skids 13 extending in a direction orthogonal to the paper surface in FIG.

In such a state, a plurality of works W cut and processed by, for example, a shearing machine are sequentially stacked on the skid 13 as shown in FIG. The work guide device 15 is detachably placed on the upper surface of the loaded works W.

As shown in FIGS. 1 and 2, the work guide device 15 is provided with an L-shaped work holder 17 that holds a corner portion of the work W.

As shown in FIG. 2, each work holder 17 is attached to X-shaped guide bars 21A and 21B. Guide bar 21 above
Of the pair of work clamps 17 that are attached to A and 21B and face each other, one work clamp 17 is a guide bar with a pin 25, etc.
It is fixed to one end of 21A, 21B. Other work clamp 17
Is movably supported by the guide bars 21A and 21B, and an elastic member 23 such as a spring is connected to the other work pressing member 17 to urge the other work pressing member 17 side.

With the above configuration, a plurality of works W are sequentially loaded on the skid 13 on the work table 7. The plurality of works W in this state are non-uniform.

Next, the work guide device 15 is placed on the accumulated work W, and the corners of the work W are pressed by the respective work pressers 17, and the other work presser 17 by the action of the elastic member 23.
Hold in a biased state. Then, the air spring 5 as an elastic device is operated to float the work table 7, and the vibration motor 11 is driven to apply vibration to the entire plurality of works W stacked on the skid 13. When the entire accumulated works W are vibrated by the vibration of the work table, the accumulated works W become relatively easy to move horizontally relative to each other, and the work holder 17 is urged by the elastic member 23. As a result, the corners of the accumulated works W are aligned.

The present invention is not limited to the above-mentioned embodiment,
It can be implemented in other modes by making appropriate changes. For example, in this embodiment, the elastic member
Instead of 23, the work clamp 17 may be pushed with an air cylinder or the like.

[Effects of the Invention] As will be understood from the above description of the embodiment, in short, the present invention is based on the work table 7 oscillatably supported on the base 3 through the elastic device 5, and the work table 7 is attached to the work table 7. An X-shaped guide bar 21A, 2 is provided which is provided with a vibration motor for imparting vibration and which is arranged above the rectangular plate-shaped works W accumulated on the work table 7.
1B is provided with an L-shaped work retainer 17 that presses each corner of the work W from the horizontal direction, and a pair of work retainers that face each other by pressing each corner of the work W from the horizontal direction. One of the 17 work clamps 17 is appropriately urged so as to be movable in the direction of the other work clamp 17.

As is apparent from the above configuration, in the present invention, the vibration motor 11 is mounted on the work table 7 and vibrates the work table 7 itself for accumulating the works W. Then, in order to align the works W accumulated on the work table 7, L-shaped works for pressing the corners of the works W from the horizontal direction on the X-shaped guide bars 21A and 21B arranged above the works W. A presser foot 17 is provided, and one of the pair of work piece pressers 17 facing each other is biased so as to be movable in the other direction.

Therefore, according to the present invention, when the vibration motor 11 is driven to vibrate the work table 7, the vibration of the work table 7 is given to the accumulated work W and the whole work W vibrates, so that the accumulated work W is mutually vibrated. This makes it easier to move horizontally relative to. As described above, the works W are in a state where they can easily move relative to each other, and the corner portions of the works W are horizontally pressed and urged by the L-shaped work holder 17, so that the respective parts of the accumulated works W are aligned. It is a thing.

That is, according to the present invention, by vibrating the work table 7, the entire work W accumulated is simultaneously vibrated.
In addition, the structure in which one of the work pressing members 17 is movable and biased by pressing allows the stacked work W as a whole to be aligned at the same time.
