Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of the Invention The present invention relates to a printing method in which a printing ring of a character ring having a large number of printing characters at predetermined intervals is printed on printing paper via an ink ribbon by operating a solenoid. It relates to a printer for printing.

(B) Conventional technology Conventionally, as shown in FIGS. 11 (a) and 11 (b), printing is mainly performed via a swinging rod e which swings a plunger b of a solenoid a between a stopper c and d. By transmitting a spring g to the hammer holder f with tension to a print hammer h slidably mounted thereon, one of the print characters 1 (1... 1n) of the character ring k is transferred via the ink ribbon i and the print paper j. A technique of hitting and printing, and a technique of providing a buffer at one end of a plunger of a solenoid and providing the plunger directly as a printing hammer (not shown) for printing are generally known.

(C) Problems to be Solved by the Invention According to the conventional technique shown in FIG. 11, in addition to the solenoid a, stoppers c and d, a swinging rod e and a spring g
Since a hammer holder f equipped with a hammer and a printing hammer h are required, not only the number of components is large but also the size of the entire apparatus becomes large. In addition, in the technology of providing the plunger of the solenoid as a direct printing hammer for printing, not only is it necessary to process the rust prevention of the plunger, but also to obtain high quality printed matter, when the buffer is worn out. There has been no disclosure of specific techniques relating to replacement of the plunger with respect to the solenoid main body by a simple operation, and adjustment of the position of the solenoid in the front-rear and vertical / lateral directions. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the drawbacks and inconveniences of the prior art and to provide a specific technique for exchanging a plunger for obtaining a high-quality printed matter and adjusting the position of a solenoid. And

(D) Means for Solving the Problems In order to solve the above-mentioned problems in the prior art, the present invention has a printing buffer fixed to one edge of a main body made of stainless steel, and another end. A cylindrical body made of an iron material is integrally fitted to the outer periphery of the solenoid frame to form a plunger for the solenoid, and the front and rear of the solenoid frame provided between the solenoid frame mounted on the mounting bracket and the machine base. And a means for adjusting the position in the vertical and horizontal directions, and a rocking body having a magnetized magnetic shock absorber engaged with the other end of the cylindrical body of the plunger, swingably swinging around the mounting bracket, and Means for solving the problem is to provide means for temporarily stopping the rocking body at an engagement position between the other end edge and the magnetic buffer.

(E) Action When the solenoid provided with the plunger is excited for printing, the plunger is acted on by the action of the cylinder made of iron material, the magnetic force between the other end and the magnetic buffer, the plunger and the solenoid frame. It is slid toward the print type of the print ring against the tension of the spring provided between the guide tube provided on the body and the print buffer provided at one end thereof. Through the ink ribbon and printing paper,
Printing is performed on the printing paper by hitting the printing type of the printing ring. When the excitation of the solenoid for printing is released, the plunger is moved back by the tension of the spring, and the other edge is buffer-adsorbed by the magnetism buffer, and is restored and stopped. Next, the temporary stopping means of the rocking body provided with the magnetic buffer is released, and the rocking body is rocked in the direction of disengaging from the other end of the plunger cylinder. The plunger slides slightly with the magnetized buffer in the direction of removal from the solenoid and stops at a position that is easy to remove by hand. The solenoid and thus the plunger are fixed at the adjusted position by operating the position adjusting means in the front-rear direction and in the vertical and horizontal directions.

Therefore, after slightly unscrewing the seat screws 23 'and 23',
After the supporting bracket 11 is swung around the screws 24, 24, the seat screws 23 ', 23' are tightened so that the vertical position of the solenoid frame 2 (therefore, the solenoid 1) with respect to the mounting bracket 10 is elongated. It can be adjusted by 16 minutes. As described above, the mounting bracket 10 provided with the solenoid frame 2 (accordingly, the solenoid 1) is inserted into the long holes 13 and 13 ', respectively, and inserted into the long holes 1 and 13'.
The seat screws 26, 26 'having a diameter smaller than the sizes of 3, 13' are screwed into the screws 28, 28 'drilled in the machine base 27, respectively, and provided on the machine base 27. Therefore, by slightly unscrewing each of the seat screws 26, 26 'and then moving the mounting bracket 10, the seat screws 26, 26' are tightened.
For the machine base 27, the mounting bracket 10 (accordingly, the solenoid 1)

In this position, one side surface 35 of the magnetic magnet buffer 35 of the rocking body 29 is engaged with the other end 8 of the cylindrical body 8 of the plunger 6. Further, the stop rod 42 is slid against the tension of the spring 43 by the knob 41, and the protrusion 38 is disengaged from the stop hole 46, so that the rocking body 29 is magnetized. When swinging together with 35 in the direction indicated by the arrow in FIG. 2, the swinging body 39 swings while sliding the plunger 6 by the magnetic force of the magnetic buffer 35, so that the plunger 6 can be easily pulled out of the solenoid 1 by finger. It can be located in any position. (Figs. 7 and 8 show the state between them.

In the drawings, reference numerals 47 and 48 denote snaps and grooves for attaching the flange 40, and reference numeral 49 denotes a screw for attaching the knob 41.

(G) Effect of the Invention As described above, since the main body of the plunger of the present invention is formed of stainless steel, it does not need to be rust-proofed at all, unlike a conventional one, and can not only endure long-term use,
The plunger can be operated without any trouble as a printing hammer by excitation of the solenoid by the cylindrical body made of iron material fitted to the outer periphery of the other end, and the wear of the printing buffer provided at one edge of the plunger Occasionally, the gap between the shock absorber and the character ring is so small that it is difficult to replace the shock absorber, and even in the case of exchanging each plunger, the rocking body equipped with the magnetic shock absorber is swung from its parking position. Not only is it easy to pull the plunger out of the solenoid body by hand, but it is also convenient, and the impact when the plunger is returned after printing is magnetized. In addition to being able to prevent vibration and generation of impulses by being buffered by the abutment with the buffer, the overall size can be made smaller than that of the conventional one. With simple and easy operation, the position of the solenoid (accordingly, plunger) in the front-rear and vertical / horizontal directions can be reliably adjusted with respect to the machine base (according to the character ring), and in order to obtain high-quality printed matter. The effects of the present invention, such as being extremely effective, are enormous.
