Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a punching device in an automatic marking device.

Traditionally, steel mills have produced steel products of different qualities (ingots, blooms, billets, wire rods, bars, etc.) for various uses.
H-shaped steel, coil material, plate material, and various other shapes) are produced in large numbers.

Among these, there are many that have the same shape but different quality.

In such cases, products of different quality often mix with each other, causing serious trouble in subsequent processes.

The most effective means to prevent this is to record necessary characters, symbols, etc. (for example, Rondo number, material, unit weight, and various other data) during or immediately after steel production for the purpose of subsequent identification. A method of marking (display) is used.

This method uses a stencil method in which a stencil material made of paper, metal foil, etc. is punched out with the marking content, and a stencil is placed on the material to be marked, and paint is sprayed from above.

In the punching device of an automatic marking device using this stencil method, punch pins are arranged in a row at equal intervals in a direction perpendicular to the direction of movement of the stencil material, and the stencil is created by punching the stencil material with the punch pins. There is.

However, with this perforation device, if the marking contents, such as characters, symbols, etc., are formed by, for example, five equally spaced rows of points perpendicular to the advancing direction of the stencil material, the stencil material can be removed in one go. One character of the stencil is formed by transporting the stencil by the distance between the rows and simultaneously punching one row with a punch pin five times.

Therefore, the signal to activate the punch pin is output five times for one character, symbol, etc. of the marking content, and this signal becomes a complete signal each time, so the leg restraint device outputs the output signal to the punch pin. However, it has a complicated structure and is expensive, making it unsuitable for use as a punching device with markings of about 10 digits.

The present invention has been made in view of the above-mentioned drawbacks of the conventional art, and includes a plurality of punch pins for punching holes in the stencil material, which are arranged in rows at equal intervals in a direction parallel to the direction in which the stencil material travels and in a direction perpendicular thereto. There are two punch groups whose punch pin arrangements are different and which form a regular lattice arrangement when superimposed, and a simple method for alternately operating the predetermined punch pins of these two punch groups and the conveying means for the stencil material. A control device is provided, and according to the signal from this control device, one character, symbol, etc. of the marking content is formed by punching twice with the punch pins of two punch groups. It is an object of the present invention to provide a punching device for an automatic marking device that can be easily manufactured and has an inexpensive control device.

There are two punch groups that form a regular lattice arrangement when superimposed, and one character or symbol of the marking content is formed as a dotted character by punching the punch group twice with the punch pin, so that the marking content is 10. Even for girders, stencils can be easily created.

In addition, since one character or symbol of the marking content can be punched out twice using the punch pins of two punch groups as described above, the control outputs a signal that alternately operates the punch pins and the stencil material conveying means. This device has great industrial value because it can simplify the structure of the device and reduce its price.
