[Example] Hereinafter, an example of the present invention will be described with reference to illustrated examples.

FIG. 1 is a schematic view showing one embodiment of the present invention, and FIG.
5 to 5 are schematic diagrams used to explain the operation of the present invention.

In FIG. 1, in a work aligning apparatus according to the present invention, a frame 40 for positioning an aligning pallet 30 is fixed on a vibration table 20 provided on a base 10.

A work supply device 50 is provided above the frame 40, and a work collection device 60 is provided below one side of the frame 40. Above the work collecting device 60, a moving device 70 for the alignment pallet 30 is provided.

Here, although a detailed description is omitted, the base 10 is internally provided with a vibration generating device for vibrating the vibration table 20 and a tilting device for tilting the vibration table 20. Further, here, as the vibration generating device, for example, a rotating body that performs eccentric rotation can be used.

The alignment pallet 30 has alignment holes (not shown) that match the shape of the work in order to align and hold the work on its upper surface.
Are formed by drilling many.

Further, the frame body 40 is for positioning the alignment pallet 30 inside, and is provided so as to be higher than the alignment pallet 30 and is opened and closed by an opening and closing device 80 provided on the collection device 60 side. It is formed by providing a freely openable and closable part 41.

The vibration table 20 is provided with a negative pressure suction device 90 for fixing the alignment pallet 30 to the vibration table 20 by negative pressure suction. The negative pressure suction device 90 is connected to an external negative pressure generating source. Connected to 91.

Next, the operation of the work aligning apparatus according to the present invention, that is, the work aligning method will be described.

First, the alignment pallet 30 is positioned on the moving device 70. The positioning of the alignment pallet 30 on the moving device 70 in this manner can be performed manually, but a transfer device for transferring the alignment pallet 30 in a direction penetrating the drawing is provided in the moving device 70 in FIG. Provision can also be made to automate positioning of the alignment pallet 30 on the moving device 70.

Next, the opening / closing part 41 of the frame body 40 is opened by operating the opening / closing device 80 of the frame body 40.

Thereafter, the alignment pallet 30 is positioned inside the frame 40 using the moving device 70 from the opened opening / closing section 41 (see FIG. 2).

After the aligning pallet 30 is positioned inside the frame 40 by the moving device 70, the aligning pallet 30 is fixed to the vibration table 20 by negative pressure suction using a negative pressure generating device.

Next, the opening / closing device 80 is operated to close the opening / closing portion 41 of the frame body 40.

Thereafter, a large number of works are supplied from the work supply device 50 onto the alignment pallet 30 inside the frame 40.

After the work can be aligned in this way, the vibration table 20 is tilted while vibrating the vibration table 20 for a necessary time to align the work in the alignment hole of the alignment pallet 30 (third).
See figure).

In this way, the vibration table 20 is tilted and vibrated for the required time, and after the workpieces are aligned in the alignment holes, the alignment pallet 30 is tilted so that the opening / closing part 41 is located below, and the vibration and tilting are stopped.

Vibration table 20 after the workpieces are aligned in the alignment holes
After the operation for stopping the vibration and the inclination of the frame 40, the opening / closing section 41 of the frame body 40 is opened by the opening / closing device 80.

After the opening / closing section 41 of the frame body 40 is opened, the vibration table 20 is vibrated again. Then, since the vibration table 20 is inclined, the alignment pallet 30 fixed to the vibration table 20
Above, the work that has not entered the alignment hole slides down along the slope, and eventually falls into the work collection device 60 (see FIG. 4).

With the opening / closing part 41 of the frame body 40 opened in this way,
Even if vibration is applied while the vibration table 20 is tilted,
Alignment pallet 30 is vibrated by vacuum suction device 90
The alignment pallet 30 does not fall off the vibration table 20 because it is fixed by suction to the table 20.

After that, the vibration table 20 to which the alignment pallet 30 is fixed by suction is brought into a horizontal state, and then the operation of the negative pressure suction device 90 is stopped.

Thereafter, the alignment pallet 30 on the vibration table 20 is taken out of the frame 40 by operating the moving device 70 (see FIG. 5).

By this series of operations, the work of fixing the frame body 40 to the alignment pallet 30 is performed.
Work to fix on the pallet 20, work to supply many works on the pallet 30, work to remove the pallet 30 with the frame 40 fixed from the vibration table 20, work to remove the frame 40 from the pallet 30, pallet The operation of removing the work remaining on the pallet 30 from the alignment pallet 30 has been fully automated.

Although a detailed description is omitted, if a return device for automatically transferring the work collected by the work collecting device 60 to the work supply device 50 is provided, a large number of works are arranged on the alignment pallet 30 from the supply device 50. Even if a large number of works remain on the alignment pallet 30 after the completion of the alignment, the next supply can be automatically performed from the collection, so that further automation can be achieved.

Also, the fixing of the alignment pallet 30 to the vibration table 20 has been described as suction fixing by the negative pressure suction device 90, but vibration is applied while the opening / closing part 41 of the frame 40 is opened and the vibration table 20 is inclined. However, as long as the alignment pallet 30 does not fall off the vibration table 20, other fixing means, for example, means for attracting magnetic force, fixing by pressing, or the like can be used.

Also, at this time, a supporting member that does not drop the alignment pallet 30 from the vibration table 20 even when vibration is applied while the opening / closing portion 41 of the frame body 40 is opened and the vibration table 20 is inclined is moved to the vibration table. By providing it on the opening / closing part 41 side of 20, the fixing means can be omitted. However, in this case, it is necessary to perform a movement that straddles the support member when supplying and collecting the alignment pallets 30 by the moving device 70.

Furthermore, after the workpieces are aligned in the alignment holes, the alignment pallet 30 is tilted so that the opening / closing part 41 is located below, and the vibration and tilting are stopped.However, only the vibration is performed with the tilted state. The work is collected by opening the opening / closing section 41 with the opening / closing device 80 continuously.
It can be formed so as to be recovered in 60.

[Effects of the Invention] As described above, the present invention makes it possible to automate work that has conventionally been performed by various manual works, thereby increasing the efficiency of work alignment on an alignment pallet and improving the efficiency of work alignment. This is for speeding up.
