Abstract

PURPOSE:To ensure the stamping of a lot number on the ear of an anode, by a method wherein a spherical part is formed on one of a stamping part and a pressing part, a spherical seat slidably engageable with the spherical part is provided on the other part, and the stamping part is connected to the pressing part rotatably about the center of the spherical part. CONSTITUTION:When an anode 1 transported within a cooling tank 10 reaches a stamping position, support parts 14, 14 are raised to hold and lift an ear part 2 of the anode 1. The anode 1 is pushed leftward by an arm 18, whereby the ear part 2 is located at the stamping position. The actuation of a cylinder 23 causes a travel part 24 of a pressing part 21 to move, whereby an abutting board 45 abuts against the upper surface of the ear part 2 with an inclination along its gradient to abut thereagainst in parallel with the upper surface. The further movement of the travel part 24 engages a spherical part 30 formed on the tip end of a pressing shaft 27 with a spherical seat 37 of a stamping holder 34, rotates the stamping holder 34 about the center of the spherical part 30, and consequently causes a printing part 36 to abut on the upper surface of the ear part 2 in parallel. The printing part 36 gives an impacts on the upper surface of a plate 24a with a cylinder shaft 50a, thereby stamping a lot number on the upper surface of the ear part 2 of the anode 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a stamping mechanism in an anode numbering device for stamping loft numbers and the like on cast anodes.

``Prior art'' Generally, anodes cast into plate shapes used in copper electrolytic refining are produced in refining batches in order to control the entry of impurities into the electrolytic tank and the actual yield of Au and Ag. Lot management is carried out separately for each type.

Conventionally, in order to perform this kind of lot management, as shown in Fig. 3, the lot number was written directly on the upper surface of the ear part 2 of the anode l with paint, or the lot number was written on the end surface of the anode l with several types of paint. This has been done by painting with a combination of colors or changing the location of the anode for each lot, but this has had the following drawbacks.

That is, when writing with paint, numbers are difficult to read because the upper surface of the ear portion 2 of the anode 1 is narrow. ■Also, in the case of color combinations, the colors may fade, and as the number of lots increases, the combinations become more sloppy, making it difficult to immediately judge the lot. ■Furthermore, if you change the anode storage location for each lot, you will need a large number of storage locations.
(If anode 1 from a different lot is mixed in,
I just can't tell the difference. In addition, in the case of ■ and ■, both were done by hand, so it took a lot of time to enter the lot.

"Problems to be Solved by the Invention" Therefore, as a method to solve the above-mentioned drawbacks, it is conceivable to manually stamp the lot number on the upper surface of the ear part 2 of the anode l using a punch, etc., but in this case, However, there are disadvantages in that it requires manpower and is likely to cause stamping errors. In order to solve this drawback, it is necessary to develop a device that automatically stamps the lot number on the upper surface of the ear portion 2 of the anode L.
Because the slope of the top surface differs slightly depending on the mold,
There is a need to develop an engraving mechanism that reliably engraves lot numbers on the upper surfaces of these different slopes.

"Purpose of the Invention" This invention was made in view of the above circumstances, and an object thereof is to provide a stamping mechanism for an anode numbering device that can easily and reliably stamp a lot number on the ear portion of an anode. It is closed.

"Means for Solving the Problems" The stamping mechanism in the anode numbering device of the present invention includes a stamping part and a pressing part that presses the stamping part against the ear part of the anode and is struck by a striking part. A spherical part is formed, and a spherical seat is formed on the other side to slidably engage with the spherical part, and the stamped part is connected to the pressing part so as to be swingable around the center of the spherical part. It is a feature.

"Operation" In the stamping mechanism of the anode numbering device of the present invention, when pressing the stamping part against the upper surface of the ear part of the anode, the pressing part and the stamping part are pressed against each other according to the slope of the upper surface of the ear part. The spherical part formed on one side and the spherical seat formed on the other slide, and the engraved part swings around the center of the spherical part, so that the engraved part abuts parallel to the upper surface of the ear part. Furthermore, when stamping the lot number on the upper surface of the ear part, the pressing part is struck by the striking part, and this impact is transmitted to the stamping part via the spherical part and the spherical seat, and the stamping part causes the anode to be stamped. Stamp the lot number on the top of the ear.
