The paper thus stamped is fed between a paper-discharging roller 50 and a driven roller 51, and is discharged into a paper-discharging tray 54.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an automatic numbering device for automatically numbering serial numbers of inspection sheets, unpacking check sheets, etc. in machines, for example.

The numbering process of stamping the serial number of Warabi' θ1 rights still remains in its old form even as the industry is being streamlined and simplified.

In conventional numbering work, a small numbering device is placed on top of a stack of papers, the worker presses the rod or lever of the numbering device by hand to make the mark, and then the stamped paper is ejected and placed on the next one. I was repeatedly stamping the next number on a piece of paper.

There are hydraulic press type or electric type numbering devices that do not require force for engraving, but even if such numbering devices are used, at least the feeding and removal of paper must be done manually. However, it required a lot of time and effort, and was inefficient.

Furthermore, since the work was carried out manually, it was difficult to engrave at a fixed position, the engraving position varied, and if there was an engraving frame, it was easy to protrude from the engraving frame.

Purpose This invention has been made in view of the above points, and an object of the present invention is to make it possible to efficiently and accurately write serial numbers at predetermined positions on paper.

hunting - armor The configuration of this invention will be explained below based on one embodiment.

1 to 4 show an example of an automatic numbering device according to the present invention.

- As shown in FIG. 1, the automatic numbering device according to the present invention includes a paper feed mechanism M1. Stamp stand.

It is composed of a stamp section S, a stamp section guiding and positioning mechanism M2+a stamp section driving mechanism Mfl+, a paper ejecting mechanism M4, and the like.

The paper feed mechanism M1 is a mechanism that feeds out the paper 2 set in the cassette 1 one by one to be stamped with a serial number, and in this example, it uses a fully automatic reverse roll mechanism that is also used in copying machines. Then, the front end of the paper 2 is pushed up by the lift arm 3 inserted into the opening 1a of the cassette 1 from below, and the upper surface of the top paper is pressed against the feed roller 4.

The feed rollers 4 and 5 have rotating shafts connected to each other by a connecting member 6 and are interlocked, and when a start switch (not shown) is pressed, the feed rollers 4 and 5 are rotated in the paper feeding direction (indicated by the arrow) by a main motor 8 via a chain 7. .

Then, the paper sent out from the cassette 1 by the feed roller 4 is transferred to the feed roller 5 and the 2 provided below it.
It is conveyed by being pinched by a reverse roller 9 for preventing sheet feeding.

The reverse roller 9 has a smaller coefficient of friction with the paper than the feed roller 5, and is rotated in the opposite direction to the arrow, but when the paper is fed out one by one,
As the feed roller 5 rotates, it rotates in the direction of the arrow,
When two sheets of paper are fed out in a stack, the frictional force between the lower paper and the reverse roller 9 becomes greater than the frictional force between the sheets, so the torque limiter reverses the rotation and moves the lower paper to the cassette 1. Push it back inside.

The stamp stand is a stand with a rubber mat on which the paper sent out by the paper feed mechanism M1 is placed substantially horizontally, and
A detector 15 such as a photoelectric sensor is installed near the right end in the figure. When the leading edge of the paper is detected by this detector 15, the main motor 8 is stopped in response to the signal, and the paper is fed by the paper feeding mechanism M1. Stop sending.

As shown in FIG. 2, the stamp section S has a structure similar to that of a conventional manual numbering device, and has a plurality of drum-shaped parts in a downward U-shaped outer frame 10 for stamping serial numbers. Number mark 11. It is equipped with a sequential feeding mechanism and an ink replenishing device (not shown) for the numerical marks 11, and an operating shaft 12 (see FIGS. 3 and 4) protrudes through the "-" surface of the outer frame 10.
A backing plate 13 with a printed $13a is fixedly attached to the lower end.

On the other hand, an air cylinder 20 of a stamp part drive mechanism M3 that drives this stamp part S is fixed to the upper part of a downward U-shaped support member 21 with a nut 22, and a piston rod 20a of this air cylinder 20 is supported. A threaded portion 20b extending inwardly of the member 21 and formed at its tip is screwed into the upper end of the slide block 23 whose upper portion is slidably fitted into the support member 21, and Fixed.

The slide block 23 is the third. As shown in FIG. 4, the upper end of the operating shaft 12 protruding from the outer frame 10 of the stamp part S is fitted and fixed with a set screw 25, and the hollow part 23
The spring 26 fitted into the outer frame 10 of the stamp part S
It is engaged between the upper surface 10a and the operating interval δ.

The stamp section guide positioning mechanism M2 is for moving the stamp section S to any position on the stamp stand so that it can be placed in the same room as the stamp section, and for determining the stamping position of the serial number.

In other words, the longitudinal direction of the stamp holder, which is the paper feeding direction (
A pair of L-shaped guide rails with approximately the same length as the stamp stand are installed at a predetermined height position inside the side plates 30 and 30 of this device, which are provided along the "X direction" (hereinafter referred to as the "X direction"). 31. 31 is fixed horizontally, and on this guide rail 31,
A slide frame 40 having a rectangular shape extending in the width direction of the stamp stand (hereinafter referred to as "Y direction") is placed between the side plates 30.degree. 30 so as to be slidable in the X direction.

A guide groove 30a is formed on one side of the side plate 30 slightly above the guide rail 31 and runs along approximately the entire length of the guide rail.As shown in FIG. A thumbscrew 32 is fitted into the groove 30a and screwed into a screw 40a formed on one short side of the slide frame 40.

Therefore, by loosening the wing screw 32, the slide frame 40 can be
The slide frame 40 can be fixed at the dog position by tightening the thumbscrew 32.

On the other hand, guide step portions 40bl and 40b extending in the Y direction are formed inside both long sides of the slide frame 40, and the lower end surface of the support member 21 is placed thereon. A slide block 23 is fitted and supported so as to be slidable in the Y direction.

Also on one long side of this slide frame 40 is a guide stepped portion 40b.
A guide groove 40C is formed on the upper side along the guide step 40b, and as shown in FIG.

It is screwed into a screw hole 21a formed in the lower part of the support member 21.

Therefore, by loosening the thumbscrew 41, the support member 21 can be moved together with the stamp portion S and the like supported thereby in the Y direction perpendicular to the X direction, and by tightening the thumbscrew 41, it can be fixed at that position.

The paper ejecting mechanism M4 is a mechanism that sends out the paper stamped by the stamp section S from above the stamp holder, and as shown in FIG. The paper discharging roller 50 is disposed opposite to the main motor 8 and is driven in the direction of the arrow by the main motor 8 via a chain 52.

The paper fed out while being held between the paper ejection roller 50 and the driven roller 51 is guided by an up-down reversing guide plate 53, is turned upside down, and is stacked one on top of the other in a paper ejection tray 54 inserted into the main body. It will be discharged.

Next, a numbering operation performed by the automatic numbering device having such a configuration will be explained.

First, set the paper 2 to be serially numbered in the cassette 1 with the side to be stamped facing upward.

Then, the thumbscrew 32 of the stamp part guide positioning mechanism M2
, 41, slide the slide frame 40 in the X direction and the support member 21 in the Y direction, position the stamp part S above the position on the stamp base where you want to engrave the serial number, and then tighten the thumbscrews 32 and 41. Tighten to fix the position of the stamp part S in the X and Y directions. - Thereafter, when a start button (not shown) is pressed, the main motor 8 is started, and the paper feeding mechanism M1 described above feeds the uppermost paper 2 from the cassette 1 onto the stamp stand, and the detector 15 detects the paper. When the leading edge is detected, paper feeding is stopped.

The paper ejecting mechanism M4 also operates in conjunction with the paper feeding mechanism M1, but when the first sheet is fed, there is no stamped paper on the stamp base, so the paper is not ejected.

In this way, after the paper 2 is fed to a predetermined position, the air cylinder 20 is operated, the piston rod 20a is extended, and the slide block 26 is integrated with the stamp part S into the first
It is lowered from the state shown by the solid line in the figure to the state shown in Figs. 2 to 4, and the contact plate 13 of the stamp part S comes into contact with the paper on the stamp holder and presses the paper (shown by the imaginary line in Fig. 1). . When the piston rod 20a further extends from this state, the slide block 26 is further lowered together with the operating shaft 12 by a stroke corresponding to the distance δ shown in FIG.

As a result, the number mark 11 shown in FIG. Engraved with consecutive numbers protruding from the top.

When stamping is completed, the piston rod 20a of the air cylinder 20 moves back, and the slide block 23 moves to the stamp section S.

At that time, the main motor 8 is operated again to feed the feed rollers 4 and 5 of the paper feed mechanism M1 and the paper discharge roller 5 of the paper discharge mechanism M4.
0 in the paper feed direction.

As a result, the engraved paper is fed between the paper ejection roller 50 and the driven roller 51 by the feed roller 5, and is sent out by the paper ejection roller 50 to the vertical reversal guide plate 5.
3, the sheet is turned over and discharged into the paper discharge tray 54.

At this time, the feed rollers 5 and 6 rotate simultaneously to feed the primary paper from the cassette 1 onto the stamp stand, and when the leading edge of the paper is detected by the detector 15, it stops.

Thereafter, the same operation as described above is repeated, and the papers in the cassette 1 are sequentially stamped with serial numbers from the top, and are held upside down in the paper discharge tray 54 in numerical order from the bottom.

Incidentally, according to this embodiment, it is possible to automatically number about 120 sheets per minute. Moreover,
The position of the engraving remains constant, and even if the engraving location on the paper is removed from the frame, it will not protrude from the frame.

Also, according to this embodiment, by loosening the setscrew 25 shown in FIG.
3 and can be used by replacing it with various stamp parts that differ in number size, font type, two-digit number, ink color, etc.

Note that both side plates 30. of the stamp part guide and positioning mechanism M2.
30 and the slide frame 40 have guide grooves 3 on both long sides.
If the slide frame 40 and the support member 21 are fixed by thumbscrews from both sides by forming the stamp parts 0a and 40a, the positioning and holding of the stamp part will be more reliable.

Furthermore, the stamp portion drive mechanism M3 is not limited to an air cylinder, but may also be a hydraulic cylinder, an electromagnetic actuator, or the like.

Furthermore, the vertical reversal guide plate 53 may be omitted, and the engraved paper sent out by the paper ejection roller 50 and the driven roller 51 may be ejected as is into the paper ejection tray. Furthermore, by using the automatic numbering device according to the present invention, the efficiency of numbering work in which serial numbers are stamped on a large number of sheets of paper can be greatly improved.

Moreover, the marking position can be set arbitrarily, and the marking can be accurately placed at a predetermined position, and the marking will not protrude from the designated frame.
