Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a stamp pad used in an automatic marking device for insulators.

(Prior Art) Conventionally, in the glazing process of insulators, the company name and stamp are stamped on a plate material 42 made of copper, as shown in Fig. 8.
A stamp pad 41 having recesses 43 for year, month, etc. is used. To mark the surface of a product such as an insulator using this stamp pad 41, as shown in FIG.
(colored mark material) is removed from the recess 4 using a scraper 44.
3, and stamp pad 4 as shown in FIG.
1. After applying a pad 45 made of silicone rubber or the like from above to adhere the Goss G in the recess 43, the pad 45 is applied to the surface of the product such as an insulator to transfer the Goss G to the product surface and mark the mark. I was wearing it.

Furthermore, there has conventionally been a method of making marks using an endless stamp pad 46 made of endless cloth, as shown in FIG. This is done by transporting the endless stamp pad 46 made of cloth by a drive device to make the Goss G in the Goss storage tank 47 adhere to it, and smoothing the Goss G deposited on the stamp pad 46 to a constant thickness with a scraper 44 to create an endless stamp. stand 4
A stamp 48 on which the company name, year, month, etc. are engraved from above is attached to the product 6, and Goss G is adhered thereto, and then this stamp 48 is applied to the surface of the product such as an insulator to make a mark.

(Problem to be solved by the invention) However, in the former case, if the part of the stamp pad 41 other than the recess 43 and the pad 45 are scratched,
Goss G remains in these scratches, and when stamping the product, extra Goss G is deposited and creates an unnecessary pattern, lowering the value of the product, making it difficult to manage the stamp pad 41, and making it difficult to manage the stamp pad 41. stamp pad 4
There was a problem in that it was necessary to prepare a large number of stamp pads in order to replace the stamp pads 1 and 1, resulting in high costs.

In addition, in the latter case, because the Goss G is attached to the endless stamp pad 46 made of cloth,
Goss G dries quickly and it is difficult to make Goss G uniform in thickness. Therefore, marks on the product surface tend to be dark and dark, and the amount of Goss G used is large, resulting in high costs. .

In addition, Goss G and endless stamp pad 46
The problem was that it was difficult to manage.

Structure of the Invention (Means for Solving the Problems) In order to solve the problems of the conventional stamp pad, the present invention has a stamp board that is larger than the bottom surface of the stamp of the insulator mark and has a substantially uniform shape on the plate material. A structure is adopted in which a deep goss storage hole is provided.

(Function) Since the present invention adopts the above-mentioned means, when stamping the insulator mark, a fixed amount of goss with an almost uniform thickness is attached to the stamp, and this goss is transferred to the surface of the product such as the insulator, so that it is clear and A mark of uniform density is placed on the product surface.

In addition, this stamp pad does not need to be replaced every month, so it has a long service life, and any stamp with a smaller bottom than the Goss reservoir hole can be replaced, and marking work on insulators is inexpensive. It will be held on.

The depth H1 of the dirt storage hole 37 is preferably in the range of 0.04 to 0.12 mm, preferably 0.05 to 0.09 mm. In this embodiment, the depth is 0.07 mm. If the depth H1 of this goss reservoir hole 37, that is, the thickness of the goss G adhered by the stamp 32, is less than 0.04 mm, the color development after firing will be poor, and if it is more than 0.12 mm, the thickness of the goss G adhered by the stamp 32 will be less than necessary. Goss G is attached, and the mark bleeds when stamped on the product, and the company name, year, and
The clarity of marks such as the moon is low, reducing the value of the product.

Next, the operation of the stamp pad 9 configured as described above will be explained.

First, as shown in Figure 6a, both scrapers 1
Supply Goss G on the stamp pad 9 between 6 and 17,
The cylinder 13 shown in FIG. 2 is operated to move the piston rod 14 backward, the support shaft 12 is rotated counterclockwise to move the scraper 16 downward, and the scraper 17 is moved to an upper position away from the stamp pad 9. let At this time, the scraping piece 16a is pressed against the stamp pad 9.

On the other hand, when the cylinder 24 shown in FIG. 4 is operated to move the piston rod 25 backward, the rotating plate 22
is rotated to the lower position as shown in FIG.
As shown in FIG. 1A, the stamps 32 are held in the stopper state of the corresponding stamp pad 9 at a predetermined interval in the goss reservoir hole 37.

When the cylinder 6 shown in FIG. 2 is operated to move the piston rod 7 backward and the stamp pad 9 is horizontally moved in the direction of the arrow P as shown in FIG. Hole 3

Next, the piston rod 14 is advanced, the support shaft 12 is rotated clockwise as shown in FIG. 6c, and the scraper 17 is moved downward to remove the sliding piece 17a.
is pressed against the stamp pad 9. Then, the piston rod 7 is moved forward to set the stamp pad 9 as shown in FIG. 6c.
When horizontally moved in the direction of the arrow Q, the excess goss G protruding from the goss reservoir hole 37 is removed from the sliding piece 1.
7a, and a certain thickness of goss G is left in the goss collecting hole 37.

When the cylinders 27 and 30 shown in FIG. 5 are actuated to move the piston rods 28 and 31 forward, the stamp 9 is moved downward, and the rubber stamp part 35 is inserted into the goss G in the goss reservoir hole 37 as shown in FIG. 6d. be contacted. At this time, the rubber stamp portion 35 is temporarily inserted into the dirt storage hole 37.
The bottom surface of the goss G comes into contact with the surface of the goss G due to the cushioning effect of the cushion material 34.

Next, when the piston rods 28 and 31 are retracted and the stamp 32 is moved upward as shown in FIG. 6e, the rubber stamp portion 35 has a uniform thickness (equal to the depth H1 shown in FIG. 1). Goth G is attached.
Here, the piston rod 25 is advanced to rotate the rotating plate 22 to the upper position, and the stamp 9 is rotated to the horizontal position as shown by the two-dot chain line in FIG. 6e.

In this state, when the piston rods 28, 31 are moved forward and the stamp 32 is brought into contact with the surface of a product such as an insulator, the Goss G is transferred to the surface of the product and a mark with a clear and uniform density is formed. At this time, the support shaft 12 is rotated counterclockwise to move the scraper 16 downward, and after the stamp 32 has moved upward, the stamp stand 9 is moved horizontally in the direction of the arrow P, and in the same manner as described above, the dirt storage hole is removed. 37 is filled with Goss G.

Now, in this embodiment, the goss collecting hole 37 which is larger than the bottom surface of the stamp 32 of the insulator mark and has a uniform depth H1 is provided in the plate material 36 made of copper, so that the goss G having a uniform thickness is formed. Since this Goss G is attached to the stamp 32 and transferred to the surface of a product such as an insulator, a clear mark with uniform density is provided on the product surface.

In addition, the stamp pad 9 does not need to be replaced every time the mark changes, so it has a long service life.
Since the protective layer 38 made of chrome plating is provided on the surface of the stamp pad 6, it is highly durable and easy to manage.Even if the surface of the stamp pad 9 is damaged, the stamp 3
No excess Goss G will be attached to the product, and the marks made on the product surface will be accurate.

Furthermore, if the stamp has a smaller bottom than the Goss reservoir hole 37, it can be replaced, and marking work on the insulator can be done at low cost.

Note that the present invention is not limited to the above-mentioned embodiment, and may be implemented by forming the goss reservoir hole 37 at a depth of H2 at the middle part and at a depth of H3 at both ends, as shown in FIG. good. The relationship between depth H2 and depth H3 is 0.12
mm＞H2＞H3＞0.04mm.

Further, in the embodiment described above, the dirt storage hole 37 was formed by the corrosive action of acid, but it may also be formed by mechanical digging.

Further, the material of the plate material 36 may be made of stainless steel or hard plastic, for example, instead of copper. Further, the protective layer 38 may be omitted.

Effects of the invention As detailed above, the present invention provides a plate material with a goss storage hole that is larger than the bottom of the stamp of the insulator mark and has a substantially uniform depth, so that the stamp has a substantially uniform thickness. As a result, the surface of products such as insulators can be clearly and
Marks with uniform density can be stamped. Further, this stamp pad does not need to be replaced every time the mark changes, has a long service life, is easy to handle, and can be easily managed. Furthermore, if the stamp has a smaller bottom surface than the Goss reservoir hole, it can be replaced and used, and it is of high practical value because marking work can be done at low cost.
