Description

[Detailed explanation of the invention] Conventionally, postmarks on revenue stamps etc. attached to various application forms, etc. have been manually rolled over the surface of the stamp using a postmarker that combines a gear and a rubber spacing wheel. However, in the case of high-quality paper weighing 100 kg or more, it requires a great deal of force, which is physically tiring and inefficient, resulting in defects such as unclear printing on the rubber spacing wheel. there were.

The present invention makes this automatic and electric, and easily inserts the paper between the postmark roller, which is a combination of gears and rubber rollers, and the pressure roller, which has a groove at the position corresponding to the gear of the postmark roller. It scratches the surface of the stamp and prints clearly using the rubber spacing wheel.

In addition, the location of the butterfly on this type of stamp varies depending on the format, and the butterfly is often placed on the back of the paper, so in the present invention, a postmark position setting mechanism and a speed-feeding mechanism are provided. The purpose is to save labor and improve the efficiency of the postmarking work by allowing the user to freely select the desired postmark, postmarking both the front and back sides as necessary, and speeding up the paper feed after postmarking.

The explanation will be given below according to the figures.

(1) An outline will be explained according to FIG. 1 (layout diagram of each part), FIG. 2 (connection diagram), and FIG. 3 (detailed diagram of the cam).

The paper feed roller 1, the pressure roller 12, 21, and the continuous feed reroller 13 are constantly rotated via a drive chain 29 using a drive motor 30 as a power source.

The paper inserted by the paper feed roller 1 is detected by a paper leading edge detector 2 (a photoelectric type, a microswitch type, etc. are used, but an example of a rechargeable type is shown in FIG. 2).

), the timing solenoid coil 3 operates, and the timing cam 5 and camshaft 6, which had been stationary due to the timing clutch 4, begin to rotate.

When the paper reaches the position where the paper should be postmarked by the paper feed roller 1, the front switch 8 is turned on only during a preset period by the front cam 7 semi-fixed on the camshaft 6, and the front solenoid is turned on. The coil 9 is energized, and the front postmark roller 10 is fed with ink by the front ink roller 11 while strongly pressing the paper between the front pressure rollers 12 and postmarking the paper, while the paper is sent to the continuous feed reroller 13.

If you want to perform a back postmark at the same time as the back postmark, set the back postmark instruction switch 14 to "close", and the relay 1 for back postmarking will be activated.
5 operates, and the back solenoid coil 16 is self-maintained in a state where it can be energized.

Thereafter, as in the above description, the back solenoid coil 16 is energized by the back cam 17 and the back switch 18.
The back side is postmarked by the back side postmark roller 19, the back ink roller 20, and the back pressure roller 21.

After the back postmark is completed, when the back postmark release switch 23 is turned off as the pin 22 attached to the timing cam 5 rotates, the self-holding of the back postmark relay 15 is released.

(2) Rapid feeding of the paper after the postmark is completed will be explained.

Even if the leading edge of the paper reaches the fast feed roller 13, if it is still being postmarked, the rotation speed of the continuous feed reroller 13 is reduced by the fast feed slip clutch 24, and at the same time when the postmarking is completed, the rotation of the continuous feed reroller 25 is stopped. It is released outside the vessel at a speed corresponding to the ratio.

In addition, if there is still paper on the paper feed roller 1 even though the postmark has been completed, the paper feed roller idling section 26
Accordingly, the paper feed roller 1 rotates idly according to the speed of the paper, thereby preventing damage to the paper.

(3) Setting the position of the postmark will be explained.

To set the left and right position of the postmark, use the postmark roller 10.19,
This is done by moving the ink roller 11.20 and the pressure roller 12.21 from side to side.

Setting the front and rear positions of the postmark and the length of the postmark surface will be explained with reference to FIG.

The front and back positions of the postmark location are set by rotating the front cam 7 and back cam 17 semi-fixed on the cam shaft 6 and changing the angle with the timing cam 5.

The length of the postmark surface can be determined by rotating the adjustment cam 27, which is semi-fixed with an adjustment bolt, in accordance with the front cam 7.
This is done by changing the length of.

The same applies to the back cam 17.

(4) Explain the case of using a dedicated postmarker in a certain format.

When using a dedicated postmarker in a certain format, paper leading edge detector 2
The paper feed roller 1 can be omitted by appropriately arranging the positional relationship of the front postmark roller 10, the back postmark roller 19, and the continuous feed reroller 13.

When the paper leading edge detector 2 detects that the paper has been inserted into the position to be postmarked, the timing cam 5 immediately starts rotating as described above, and at the same time, the front side cam 7 and the front side switch 8 turn on the front side solenoid coil. 9 is energized, the paper is sent to the continuous feed reroller 13 while being postmarked by the front postmark roller 10, and is discharged from the device as soon as the postmark is completed.

The same applies to the back postmark.

As explained above, with this invention, by creating a dynamic eraser with a postmark mechanism, a postmark position setting mechanism, and a fast-feeding mechanism, it is possible to significantly improve the postmarking work that was previously done manually, and to The postmarking process can be done efficiently, clearly, and reliably.
