Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a transfer table used for transferring articles underwater using an electromagnetic feeder.

It is well known that electromagnetic feeders are used to transport goods in the air, and that they function satisfactorily.

However, if you use an electromagnetic feeder to transport thin and light items, such as ceramic elements for capacitors, by ultrasonic cleaning, the ceramic elements to be processed must be transported underwater, which requires air Items cannot be transferred as smoothly as inside.

As a result of experiments, the inventor of the present invention confirmed this fact, and improved the structure of the transfer table so that it can reliably transfer especially thin and light items by using an electromagnetic feeder, which is extremely convenient for transferring items, and achieved good results. Obtained.

Fig. 1 is an outline of the electromagnetic feeder used underwater, and Fig. 2 is a plan view showing the structure of the transfer table according to the present invention.
FIG. 3 is a perspective view including the transfer table.

In Fig. 1, 1 is a drive electromagnetic coil, 2 is a housing, 3 is a transfer table, 4 is a water surface, and 5 is an aperture with a group of small holes (see Fig. 3). This arrangement is designed to irradiate ultrasonic waves from a vibrator (not shown) into the housing 2.

When the electromagnetic coil 1 is energized and driven, the housing 2 vibrates,
When placed on the transfer table 3, transverse vibration (arrow A) and longitudinal vibration (arrow B) occur.

In this case, since the transfer table in a normal electromagnetic feeder is a flat plate without any processing on its surface, when the structure vibrates, vibration pressure is applied to the product through the water. Because the environment is different from that in the air, even if the transfer table vibrates, the items on it only move up and down with the water and are not transferred.

Therefore, as shown in FIGS. 2 and 3, by providing a large number of holes 7 distributed over the entire surface of the transfer table and smaller than the size of the item 6 to be transferred, water will pass through the holes 7 and the feeder When the casing 2 vibrates, the product is transferred by the lateral vibration shown at A.According to experiments, a ceramic element for a capacitor with a thickness of 0.3 mm and a diameter of 6 mm can be transferred in 10 seconds for a 600 mm diameter. I was able to transfer it.

As described above, the present invention is a simple procedure of providing a suitable group of holes on the transfer table of a conventional electromagnetic feeder, and can fully demonstrate the function of the electromagnetic feeder even underwater, especially for thin and light items. The effect is large.

Also, although this explanation has been given in the case of water, it goes without saying that the same effect can be achieved in other liquids as well.
