TECHNICAL FIELD This invention relates to a device for arranging small workpieces in a two-dimensional manner without overlapping them.

0002

2. Description of the Related Art Generally, a plurality of workpieces W, such as small ceramic parts, are fired at the same time, and there is a problem in that the workpieces W stick together. Therefore,
These works W are arranged in a plane without overlapping and laid out in a firing box (this kind of laying down is hereinafter referred to as flat laying), and fired thereon to prevent the works W from sticking to each other. However, firing boxes are generally heavy;
It is difficult to pack the work W directly flat on the firing box.

[0003] Conventionally, therefore, a jig made of a stainless steel plate or a resin plate with a smooth upper surface is prepared, a plurality of workpieces W are scattered on the jig, and the workpieces W are shaken manually. They packed them flat, then turned them over with the jig and transferred them to firing boxes.

[Problems to be Solved by the Invention] By the way, in such a conventional flat packing method, the workpieces W scattered on the jig are
In order to flatten the material, the worker must shake the jig many times, front and back, left and right, as well as up and down, which takes time and effort. Moreover, it is difficult to completely flatten all the workpieces W by just shaking, and it is necessary to pinch and replace the remaining workpieces W with tweezers or the like in an overlapping state until the end.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a small work aligning device that has a simple structure and can reliably align workpieces in a short time. There is.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention is an apparatus for arranging a large number of small workpieces in a plane without overlapping them, the upper surface being a smooth surface, and the upper surface A work jig with a gently uneven shape,
A workpiece alignment device was constructed by including a swinging mechanism that swings this workpiece jig in the horizontal direction.

[0007]

[Operation] According to the above configuration, when a plurality of small workpieces are scattered on the upper surface of the workpiece jig and the workpiece jig is swung horizontally by the swinging mechanism, the workpieces are smoothed by the centrifugal force of the swinging. Slide on the top surface of the jig. however,
Only the lowest layer of the overlapping workpieces comes into contact with the top of the uneven shape formed on the top surface of the jig, and its movement is weakened by friction therebetween. As a result, the overlapping upper workpiece will pop out from above the lowest layer workpiece. This action is repeated during rocking to eliminate overlapping of the workpieces.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on embodiments shown in the drawings. FIG. 1 is an external perspective view of the small work aligning device of this embodiment. This small work alignment device 1 includes a work jig 2 and a swing mechanism 3. The work jig 2 has a flat plate 5 made of corrugated cardboard attached to the upper surface of a base plate 4, and a cushion member 6 made of urethane foam is attached to the peripheral edge of the flat plate surface 5a. Also,
The surface 5a of the flat plate 5 is smooth and, as shown in the enlarged view of the main part in FIG. 3, is wavy because it is made of corrugated cardboard. In other words, the surface 5a has a gently wavy uneven shape, and the tops 7 of the surface 5a are regularly continuous.

The swing mechanism 3 is provided on the back side of the base plate 4, as shown in FIG. The swing mechanism 3 consists of an electric motor 8 and an eccentric shaft 9.
The eccentric shaft 9a is connected to the back surface of the base plate 4. Further, the electric motor 8 and the eccentric shaft 9 are interlocked and connected by a pulley 10 and a belt 11.

Next, the flat packing operation of small workpieces W (in this embodiment, small ceramic parts) by the alignment device 1 having the above configuration will be explained.

First, a large number of works W are scattered at the center of the flat plate surface 5a of the work jig 2, and then the swing mechanism 3 is driven to swing the work jig 2. That is, the electric motor 8 is driven, and its rotational drive is transmitted through the pulley 10 and the belt 11.
is transmitted to the eccentric shaft 9 through the eccentric shaft 9a, and the work jig 2 is oscillated in the horizontal direction by eccentric rotation of the eccentric shaft 9a.

Then, the works W scattered on the flat surface 5a slide on the flat surface 5a due to the centrifugal force of the swing. However, the workpieces W, which are scattered and overlapped,
In W, . . . , when the lowermost workpiece W moves on the upper surface 5a by sliding, it comes into contact with the uneven top portion 7 and its movement is weakened by friction with the top portion 7. On the other hand, the movement of the work W at the top of the overlap is not weakened, and there is a difference in movement between the work W at the bottom layer and the work W at the upper side. Therefore, the upper workpiece W jumps out from the lowermost workpiece W, eliminating the overlap. (See FIG. 4) Since this operation is repeated during the swinging, the overlap of the workpieces W is surely eliminated in a short time and the workpieces W are packed flat on the flat surface 5a.

Note that even if the workpiece W reaches the end of the workpiece jig 2 as flat packing progresses, the cushion member 6 attached to the peripheral edge of the flat plate 5 prevents the workpiece W from jumping out of the jig 2. will not fall from the work jig 2.

When the flat packing of the workpieces W is completed, the workpiece jig 2 is separated from the swing mechanism 3 and turned over on a firing box (not shown), and the workpiece is transferred to the firing box.

Incidentally, in the above embodiment, a flat plate made of a cut ball board was used as the work jig 2 having a gently uneven shape, but it goes without saying that the present invention is not limited to this.

[0016]

As described above, according to the small workpiece aligning device of the present invention, small workpieces can be aligned in a plane reliably and in a short time. Further, this device has a simple structure in which a gentle unevenness is formed on the surface of a jig for storing a workpiece, and the jig is horizontally swung, so it can be easily implemented.
