DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic printing apparatus.

[0002]

2. Description of the Related Art Conventionally, as an automatic printing apparatus, for example,
(1) JP-B-2-30871, (2) JP-A-3-
JP-A-86578 and (3) JP-A-6-227109.

[0003] However, the invention of the above (1) has a drawback that the operation of the gripper for moving up and down is not easy because the operation is a sliding type in the horizontal direction. Is a stamping device linked to the rotation axis of the motor,
I am worried about the certainty of the imprinting.
An apparatus consisting of a complicated mechanism having a control circuit is expensive.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the drawbacks of the conventional apparatus, and to provide a simple structure capable of always performing a smooth and accurate printing operation regardless of the thickness of an object to be stamped. It is an object of the present invention to provide an imprinting apparatus.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a vertical elongated hole is formed in a rear plate portion of a stamper support plate mounted on a stamper mounting base installed on the upper inside of a frame plate erected on both right and left sides of a base. And an actuating plate connected to the stamper support plate by interposing an elastic machine on the front side of the stamper support plate.
A long hole is provided, and an operating shaft provided at an upper end portion of a link provided on a rear side portion of the stamper support plate is inserted through both the long holes,
A connecting rod provided on the rear side of the lower end of the link is pivotally connected to the upper end of the crank, and the rotating shaft of the motor is connected to the lower end of the crank. The rotation of the motor rotating shaft causes the operating shaft to move up and down. In this case, the object is stamped.

[0006]

FIG. 5 shows a non-use state of the apparatus according to the present invention. In this stationary state, both the crank and the link are still in a vertical state. The operating shaft inserted between the vertical elongated hole provided in the above and the `` ku ''-shaped elongated hole provided in the operating plate on the front side is located at the upper limit in any of the elongated holes, and The initial position of the operating shaft is immovable due to an elastic force of an elastic machine interposed between the operating plate and the stamper support plate.

In order to use this apparatus, a desired stamp is prepared on the stamping surface of the stamper, and after the stamper is mounted on the stamper mount, the power switch is turned on and the motor is driven. Then, as shown in FIG. 6, the crank rotates clockwise by the rotation of the motor shaft. In this crank, the lower end of the link is pulled down in the same direction via a connecting rod pivotally supported at the upper end, so that the lower end of the link rotates clockwise and is transmitted to the operating shaft. However, in this first stage, the operating shaft is still fixed at the upper limit of the two long holes, and is also elastically biased by the elastic machine,
In this state, the stamper support plate and the operation plate start moving downward with the support shafts on both sides as guides.

Further, when the crank rotates and is positioned in the horizontal direction, the connecting rod pulls down the link in the same direction, but the operating shaft is still in a fixed state sandwiched between the upper ends of the long holes. However, in this state, the stamper support plate and the operating plate move further downward with the support shafts on both sides as guides, and the stamper comes into contact with the printing material on the base top plate.
(See Fig. 7)

When the crank further rotates, the stamper is in contact with the material to be imprinted, so that the stamper support plate and the operating plate cannot move downward, and the operating shaft is located at the upper bent portion of the "く" -shaped slot of the operating plate. The actuator moves downward while rotating the operation plate in the clockwise direction. At this time, since the operation plate rotates against the elastic bias by the elastic machine, a pressing force is applied to the rotation fulcrum of the operation plate. (See Fig. 8)

[0010] By forcibly transmitting the pressing force to the stamper, the stamper in contact with the object to be printed is pressurized and stamped.

When the operating shaft reaches the lower limit of the upper bent hole of the "ku" -shaped slot, that is, when the lower hole of the "ku" -shaped slot matches the vertical slot of the stamper support plate, the operation is started. The rotation of the plate stops, and the pressing force is released.

After a half rotation of the motor shaft, the crank also makes the next rotation by the next half rotation of the motor shaft, so that the operating shaft on the link again has the upper limit of the bent portion of the "K" -shaped long hole. To return to the original stationary state (FIG. 5).

FIGS. 9 to 11 show the printing effect for a relatively thick printing object.

The stamper comes into contact with the object to be imprinted, and the rotation of the operating plate starts, and a pressing force acts on the stamper to impress the object to be pressed. After that, the operating shaft reaches the lower limit of the bent hole of the く -shaped elongated hole of the operating plate, and the lower hole and the vertical elongated hole of the stamper support plate are aligned vertically, Is canceled. (See Fig. 9)

With further rotation of the motor shaft, the working shaft moves down the slots. At that time, since the pressing force has been released, no pressing force is applied to the stamper, and the operating shaft only moves downward. (See Fig. 10)

When the motor shaft has rotated half a turn, the operating shaft has reached the lower limit of the vertical portion of the two long holes. However, since the motor shaft is immediately rotated in the latter half, the operating shaft is perpendicular to the two long holes. Try to return above the part. (See Fig. 11)
