Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing machine that is capable of printing by type and at the same time encoding and recording by punching.

Conventionally, this type of printing machine has been a punch typewriter, but this type simply has a type drum and a punch mechanism coexisting and linked, so the structure tends to be large and complicated, and it is difficult to print using type. There were no cases in which the copy and perforation were obtained in different locations or as separate pieces, and the perforation record was obtained in the same location as the printed part.

However, as the automatic processing of information progresses, there has become a need for a device that can simultaneously print letters on various automatically processed cards, receipts, labels, etc. and simultaneously obtain corresponding perforation records at the same location.

The present invention has been developed in view of the above.

This will be explained along with an example shown in the drawings.

This embodiment is of a type drum type in which a plurality of unit type rings are superimposed, and as shown in FIG.

The type drum 1 is composed of a large number of type rings 5 stacked together as a unit, and each type ring 5 can be freely rotated independently by a conventional type setting mechanism (not shown).

Further, in this embodiment, the lower surface of the type drum serves as a predetermined arrangement location of type, that is, a printing position.

Each type ring 5 has an equidecagonal shape as shown in FIG. Type 7 for
Punch needles 8 are arranged in a coded arrangement corresponding to the printed character content (here, "3").

The encoding method is free, but here we will take the simplest number as an example and encode it in binary, 1 by I is made up of 4 bits and arranged vertically, and the bit value "1" is It is decided to drill a hole (Fig. 5).

Note that the tip of the punch 21 dollar 8 protrudes sufficiently from the upper surface of the type 7, and is made of steel.

The type ring 5 is also the same polygon but has a slightly smaller diameter.
It has a groove 9 one step lower than the side surface 6 on one side.

The secondary hammer 2 is located directly below the printing position on the type drum 1 with a gap through which the material to be printed can pass, and its upper surface is flush with the material guide plate 10.

In this embodiment, the secondary hammer 2 corresponds to each type ring 5 of the type drum 1, and has a structure in which secondary hammer elements 11, which can move up and down independently, are housed in a line in a frame 12 ( (Figs. 1 and 2) As shown in Fig. 6, the secondary hammer element 11 is
It is a rectangular steel body whose length and width are equal to each side 6 of the type ring 5, and the upper surface, that is, the surface facing the type ring 5, has a type striking surface 13 and a number (equal to the bit structure of the byte in encoding) ( Here, four holes 14 are provided in the same manner as the punch needles on the side surface of the type ring 5.

Further, a spring 15 whose both ends are engaged with the frame body 12 and has a downward biasing force is engaged with the side surface, and a guide protrusion 15 is engaged with the front and rear surfaces.
6 is provided protrudingly.

The frame body 12 allows the secondary hammer element 11 to move up and down freely within the frame body via the guide protrusion 16, and is always positioned downward by the spring 15 when no load is applied. It is held by the lower locking part so that the upper surface of the material guide plate 10 is flush with the material guide plate 10.

The hammer 3 is located on the lower surface of the secondary hammer 2 at a distance from the secondary hammer 2 during normal operation, and is supported by a pivot shaft 17 in the middle, and the other end is connected to a normal hammer drive mechanism such as a cam 18.

In the embodiment, the upper part of the hammer is divided into comb-teeth shapes so as to correspond to the respective secondary hammer elements, but this is not necessarily necessary unless printing is performed selectively on the type ring 5.

However, it is necessary to design this hammer 3 with some degree of precision so that there is no left-right vibration at the pivot joint.

As shown in FIG. It consists of a regulating plate 20, and the regulating plate 20 is connected to each type ring 5.
One sheet can move toward and away from the groove 9 in correspondence with the other.

The frame 19 has a link 22 extending from a pivoted shaft 21.
An elastic rod 23 is pivotally attached to the center of the link 22, and one end thereof is connected by a link 25 to a portion of the arm 24 of the hammer 3 closer to the recam 18 than the pivot 17.

That is, when the hammer 3 moves upward, the ring position regulating frame 4 moves downward, and the regulating plate 20 moves into the groove 9 of each type ring 5.
engage with.

At this time, the pivot position of the elastic rod 23 with respect to the link 22 and the fixed position of the link 25 with respect to the arm 24 are adjusted so that the regulating plate 20 reaches the groove 9 earlier than the hammer 3 hitting the secondary hammer 2. Keep it.

Reference numeral 26 in Figure 2 is a pressing spring with a weak biasing force whose upper end is fixed to the machine body side, and when pressed from below, its tip can move upwards from the side surface 6 of the type ring 5 at the printing position. has been done.

27 is a supply roll for the material to be printed, and 28 is a take-up roll thereof.

With the above structure, each type ring 5 is now arbitrarily rotated to set the required number of digits at the printing position, and then the cam 18 is rotated, and the hammer 3 moves upward. A secondary hammer 2 is fired toward the type drum 1.

The secondary hammer 2 presses the material to be printed between it and the type drum 1 against the side surface 6 at the printing position, the type striking surface 13 and the type 7 perform printing, and the hole 14 and the punch 21 dollar 8 performs perforation.

Therefore, since the type and punch 21 positions on each side 6 of the type ring 5 are associated with each other by encoding, the material to be printed can simultaneously obtain the necessary print and its corresponding perforation record at the same location. It will be done.

At this time, in the embodiment, the ring position regulating frame 4 moves down before the impact of the hammer 3 to press down and fix the groove 9 of the type ring 5, and the secondary hammer element 11 is also framed by the front and rear protrusions 16. Since the punch needle 8 is guided by the body 12 and its position is regulated, alignment between the punch needle 8 and the hole 14 is maintained.

Any further pressing force on the regulating plate 20 which reaches the groove 9 first and stops moving is absorbed by the deflection of the elastic rod 23.

On the contrary, it can be said that the elasticity of the bent elastic rod 23 strongly prevents the movement of each type ring.

Since the lower part of the regulating plate 20 has a concave polygonal shape corresponding to the polygonal shape, if this part is strongly pressed against the groove 9, it is possible to correct some positional deviation in the rotational direction of the type ring 5.

When printing and punching are completed, the hammer 3 descends, and the secondary hammer 2 also descends, completing the cycle.

In reality, the printing material may remain stuck in the punch 21 dollar 8, but in this embodiment, the pressing spring 26 solves this problem.

That is, the pressing spring 26 is pushed upward with the upward movement of the secondary hammer 2, and at this time, it is kept out of the way of printing and perforation, and when the secondary hammer 2 leaves the type drum 1, the type drum along with the printing material until then is pushed up. The pressing spring 26 which had been pressed at the position 1 rebounds to its original position, and at this time the printing material is pulled out from the punch needle 8.

Due to the above structure and operation, printing and perforation records can be obtained simultaneously at the same location, although the structure is relatively simple.

By adopting a secondary hammer, the alignment between the punch 21 on the type drum and the hole on the hammer is very good.The conventional type ring structure makes it easy to set the required type. The structural part is also not bulky, so it has advantages and characteristics such as being particularly suitable for small registers and printing machines.
