Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mark head mechanism, and more particularly, to a technique effective when applied to a rubber stamp transfer type mark head mechanism used in, for example, a direct mark machine.

[0002]

2. Description of the Related Art Conventionally, as a mark head mechanism of this type, there is, for example, one shown below.

That is, the mark head mechanism is a rubber stamp transfer system, and has a fixing structure in which the rubber stamp is directly attached to the head portion.

[0004]

However, in the above-described mark head mechanism, since the rubber stamp is fixed directly on the head portion, the stamp height of the rubber stamp is constant and cannot be followed. Therefore, there is a problem that only a product having a stable surface can be imprinted, and it is difficult to imprint a mark clearly on a product having an unstable surface.

Further, a product having an unstable surface must be manually stamped, which causes a problem that the mark yield is reduced.

An object of the present invention is to provide a mark head mechanism capable of automating the marking and clarifying the marking of a product having an unstable surface.

Another object of the present invention is to provide a mark head mechanism capable of extending the life of the stamp by buffering the impact generated between the stamp and the product during marking.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0009]

Among the inventions disclosed in the present application, a brief description will be given to the outline of typical ones.
It is as follows.

That is, the mark head mechanism of the present invention is
A head portion having a storage hole, a buffer member accommodated in the storage hole of the head portion, an elastically deformable plate provided in the head portion and biased in the imprinting direction by the buffer member, and the plate. The structure is provided with a mark head mechanism section including a stamp to be attached.

In this case, it is possible to adopt a structure in which a plurality of the mark head mechanism parts are arranged in parallel in the surface direction.

[0012]

According to the mark head mechanism of the present invention, a head portion having a housing hole, a buffer member housed in the housing hole of the head portion, and a head member provided in the head portion and attached in the imprinting direction by the buffer member. An elastically deformable plate that is biased,
Since the structure is provided with a mark head mechanism section composed of a stamp attached to this plate, the stamp can be made to follow the variation in the height direction of the product, the inclination due to the deviation of the parallelism, or the curved surface. .

Therefore, it is possible to improve the mark yield by automating the marking of a product whose surface is unstable and clarifying the mark.

Further, the shock generated between the product and the stamp at the time of marking can be buffered by the buffer member, and the life of the stamp can be extended.

Further, the cost can be reduced by the simple structure.

Further, by adopting a structure in which a plurality of the mark head mechanism portions are arranged side by side, a plurality of marks can be imprinted at the same time, and the marking performance can be improved.

First Embodiment FIG. 1 is a perspective view showing a mark head mechanism according to a first embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG.

The mark head mechanism in the first embodiment is applied to a case where only one mark head mechanism section 1 of the rubber stamp transfer system is provided, and has a head section 2. A rectangular storage hole 3 is formed in the head portion 2. A buffer member 4 is housed in the housing hole 3, and the buffer member 4 is made of, for example, rubber, urethane or a spring.
It projects from the opening of the storage hole 3.

A plate 5 is screwed onto the head portion 2 via screws 6, and the plate 5 is, for example, about 0.1 to 0.5 mm.
The elastically deformable strip plate having a thickness of 5 mm is configured to be biased in the imprint direction by the buffer member 4 protruding from the opening of the storage hole 3. A stamp 7 such as a rubber stamp is attached to the center of the plate 5 with an adhesive.

Next, the operation of the first embodiment will be described.

When a product having an unstable surface is marked by using the mark head mechanism having the above-described structure, the plate 5 is elastically deformed by the cushioning member 4 when the stamp 7 is made to face the product. Since the structure is possible, the mark 7 is imprinted by following the surface of the product 7 in the height direction of the product, the inclination due to the deviation of the parallelism, or the curved state.

Therefore, it is possible to improve the mark yield by automating the marking of a product whose surface is unstable and clarifying the mark.

Further, the shock generated between the product and the stamp 7 at the time of marking can be buffered by the buffer member 4 to extend the life.

Further, the cost can be reduced by the simple structure.

[0025]

Second Embodiment FIG. 3 is a perspective view showing a mark head mechanism according to a second embodiment of the present invention.

The mark head mechanism according to the second embodiment has substantially the same structure as that of the first embodiment, but is different in that it is applied when two mark head mechanism parts 1 are arranged side by side.

More specifically, two cushioning members 4 are accommodated in the accommodating hole 3 formed in the head portion 2, and two plates 5 biased by the cushioning members 4 are screwed in parallel with each other. A seal 7 is attached to each of them.

Regarding the operation and effect of the second embodiment, in addition to the operation and effect of the first embodiment, two marks can be imprinted at the same time, and the marking performance can be improved.

Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the embodiments and various modifications can be made without departing from the scope of the invention. Needless to say.

For example, in the second embodiment, a case has been described in which two mark head mechanism units are arranged side by side in the plane direction, but the present invention is not limited to this, and a plurality of mark head mechanism units such as three or four are arranged in parallel. It can also be installed.

[0031]

The effects obtained by the typical ones of the inventions disclosed in the present application will be briefly described as follows.
It is as follows.

(1) A head portion having a storage hole, a buffer member accommodated in the storage hole of the head portion, and an elastically deformable member provided on the head portion and biased in the imprint direction by the buffer member. Since the structure is equipped with a mark head mechanism that consists of a flat plate and a stamp that is affixed to this plate, the stamp can follow the surface of a product that is uneven in the height direction, tilts due to deviation of parallelism, or curved. Can be made.

(2) Due to the effect of the above (1), it is possible to improve the mark yield by automating the marking of a product whose surface is unstable and clarifying the mark.

(3) The shock generated between the product and the stamp at the time of marking is cushioned by the cushioning member, and the life of the stamp can be extended.

(4). The cost can be reduced by the simple structure.

(5) In the case of (1) above, a plurality of marks can be imprinted at the same time by using a structure in which a plurality of mark head mechanism parts are arranged in parallel in the surface direction, and the marking performance can be improved.
