DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for engraving a case for an electrolytic capacitor, and more particularly to an apparatus for engraving characters, numerals, etc., on the outer surface of the case, such as the rating, specification, and serial number of the electrolytic capacitor. is there.

[0002]

2. Description of the Related Art Conventionally, in the manufacturing process of electrolytic capacitors and the like, a device for engraving letters, numbers, etc. on the outer surface of a case has been used to clearly indicate the rating, specifications, serial number, etc. of the electrolytic capacitor. Have been.

[0003] As this type of marking device, generally, a support rod is inserted into a capacitor case from the head side to hold the case, and the support rod is pressed against the bottom surface of the case to support the case. There is known an apparatus having an engraving bar for engraving a required character or the like on the bottom surface. In the case of wear, etc., it is difficult to replace it, and the pressing force of the marking bar is too strong to move the support bar, destabilizing the capacitor case at the time of marking, and obtaining a favorable marking. There are difficulties such as not.

[0004] From such a viewpoint, conventionally, for example, a bell crank is used as a connecting means for driving an engraved bar, and when this bell crank is connected to a support bar, the tip of one lever of the bell crank is formed in a spherical shape. By inserting this into a connecting hole formed in the connecting member of each of the rods, a marking device for a capacitor case capable of removing each of the bars just by removing the bolt of the connecting member. Has been proposed (Jun 51-50)
No. 995).

That is, in the marking device according to the above proposal, the lever connected to the piston rod of one bell crank connected to the support rod is connected to the piston rod of the other bell crank connected to the marking rod. By making the lever longer than the lever to be operated, even if the piston rods are operated with the same driving force, the force applied to the support bar becomes larger than the force applied to the engraved bar, so that the engraving operation is stably performed. It can be done.

[0006]

However, the above-mentioned conventional marking system reciprocates or swings a case or a marking means (marking bar) side, and a sliding portion or a pressing force for this movement. And the installation space for this must be set sufficiently.

It is characterized by being configured to rotate.

In this case, the rotating body of the case engraving / transporting means has a case storing / holding portion formed at an outer peripheral portion thereof at 90 ° intervals, and a case supplying means is provided above to drop the electrolytic capacitor case by its own weight. During the intermittent rotation operation at an interval of 90 ° in the counterclockwise direction, the case is contacted with the engraving printing wheel of the engraving means to perform engraving, and the engraving is performed by providing a discharging means below. The case can be configured to drop and discharge by its own weight.
