Description

[Detailed explanation of the invention] A. Industrial application field This invention automatically applies ink to the entire surface of the inkstone grinding surface by adding constant slow-speed left and right reciprocating motion to the back-and-forth linear movement as if using a handrail, depending on the inkstone used. This invention relates to an ink-driven automatic inking machine that allows for even and even sliding movement.

B. Conventional technology Conventionally, this type of equipment consists of an ink drive mechanism that only moves the ink back and forth linearly in one direction, and an inkstone drive mechanism that only moves the inkstone back and forth at very low speed. An automatic inking machine has been proposed in which the inkstone is moved horizontally and reciprocally at a very low speed against the inkstone that moves in a straight line back and forth, so that the inkstone can be evenly moved over the inkstone grinding surface. It consists of two drive mechanisms, a drive and an inkstone drive, and
This had the disadvantage that the structure was complicated, coupled with the fact that it had to drive a heavy inkstone.

C. Problems to be solved by the invention The problems to be solved by the invention are to simplify the two drive mechanisms as described above into one drive mechanism,
Furthermore, we have simplified the configuration by making it possible to slide ink, which is much lighter than an inkstone, evenly over the entire surface of the inkstone grinding surface, and created an ink-driven automatic ink inking machine that does not wear unevenly on the inkstone surface. That's what you're trying to get.

D. Means for Solving the Problems The present invention, as a means for solving the above problems, includes a fixed screw holder, a screw screw rotatably screwed into the screw holder, and a terminal end attached to one end of the screw rod. A fixed crank, a lever whose distal end is rotatably connected to a connecting part arranged stepwise along the length of the distal end of the crank, and an ink holder provided at the distal end of the lever; a drive device that rotates the screw rod in conjunction with the other end of the screw rod; a transport frame on which the drive device is mounted and transports the screw rod integrally with the movement of the screw rod;
It is composed of a changeover switch provided at both end positions for reversing the direction of movement of the screw rod, and at least one of the changeover switches so that it can be slid and fixed in a stepless or stepwise manner parallel to the direction of movement of the screw rod. .

E action Next, the operation of the present invention will be explained.

First, prior to use, the end of the lever can be freely rotated to the required connection part that is provided in stages along the length of the crank according to the length of the inkstone abrasive surface in accordance with the inkstone standard. Also, set the distance between the two changeover switches to the required position according to the width of the inkstone surface, attach ink to the ink holder at the tip of the lever, and place the ink on the inkstone surface. place

Next, turn on the power and operate the drive device. The screw rod rotates in one direction by the operation of the drive device, and in accordance with the rotation, the tip of the crank whose end is fixed to the screw rod performs a circular motion, and a lever rotatably connected to the tip of the crank rotates. The ink attached to the tip makes reciprocating motion along the length of the inkstone stone surface, and the screw rod is rotated one pitch at a time under the action of the fixed screw holder into which it is screwed. By moving straight in one direction, the black ink is gradually moved along the width direction of the inkstone grinding surface.

That is, one rotation of the screw rod causes the ink to reciprocate once in the length direction on the inkstone grinding surface and also to move one pitch in the width direction. Continuing its movement, when the ink reaches one end of the inkstone grinding surface, it comes into contact with one of the selector switches at that position, and the rotation direction of the drive device is reversed, causing the ink to reciprocate in the length direction on the inkstone grinding surface. While moving, it moves in the width direction toward the other end opposite to the above, and when it reaches the other end, it comes into contact with the other changeover switch at that position, and the rotational direction of the drive device is reversed again.

By continuing the above operation, it is possible to automatically move the black ink evenly over the entire surface of the inkstone stone, and the above operation stops when the power is turned off.

F. Example Hereinafter, an example of the present invention will be described with reference to the drawings.

A rail body 2 arranged in the longitudinal direction of the center of the board 1
A transport platform 3 is provided which can freely slide along the rail body 2, an overpass 4 is erected at an intermediate position of the rail body 2, and a screw rod receiver 7 with a screw hole 6 drilled therein is fixed to the lower surface of the bridge section 5. . A screw rod 8 having a screw cut on its surface is rotatably screwed into the screw rod receiver 7, and a shaft bearing body 9, which is rotatably fixed at both ends thereof, is mounted and fixed on the transport frame 3. A distal end of a crank 10 is fixed to one end of the threaded rod 8 protruding from the shaft bearing 9, and a plurality of connecting holes 11 are formed at required intervals along the length of the distal end of the crank 10. The distal end of the lever 12 is rotatably connected to a required connecting portion formed by drilling, and the ink holder 1 is attached to the distal end of the lever 12.
3 is provided.

At the other end of the screw rod 8 is a drive device 16 consisting of a motor 14 and a speed reducer 15 for rotating the screw rod 8.
The drive device 16 is mounted on the transport frame 3.

At a predetermined position near the side of the transport frame 3 in the moving direction, a screw rod 8 is installed to change the rotational direction of the drive device 16.
Switches 17 and 18 are disposed at both end positions where the direction of movement is reversed, and at least one of the switches 17 is set in a stepless or stepwise manner parallel to the direction of movement of the screw rod 8, that is, the direction of movement of the transport frame 3. It is configured to be slidable and fixed, and an engaging element 19 is attached to a predetermined position of the conveyance frame 3 so as to abut and engage with the levers of the changeover switches 17 and 18 when the engaging element 19 is moved. A door 21 can be opened on the side surface, and a lever 12 can be extended from the door opening, and a handle 22 is provided on the upper surface of the top plate of the box so that it can be carried. A is ink, and b is an inkstone. Note that electrical wiring and electrical parts are omitted.

Effects of the invention As is clear from the above explanation, the present invention fixes a heavy inkstone, moves much lighter ink ink to the inkstone grinding surface along its length, and moves it across its width. By reciprocating at a constant slow speed in the direction, the ink is able to slide evenly over the entire surface of the inkstone stone.
It is a rational device that has a simplified configuration and does not cause uneven wear on the inkstone surface.
