Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a device for removing base paper attached to a printing plate of a mimeograph machine.

Mimeograph paper is attached to a plate made of a cylindrical body with many small holes formed in a metal plate, etc. wrapped around a cloth screen, etc., and ink is supplied from inside the plate and leached out from the plate-making perforations of the base paper. In so-called mimeograph machines, which print on paper fed between a printing plate and a press roller that presses it onto the printing plate, it is necessary to remove the printed base paper from the printing plate. This is the most troublesome work as it is easy to get dirty with hand ink.

In recent years, this removal work has been automated, and ilS! There is a tendency to be equipped with a base paper removal device that automatically strips the base paper from the plate and throws it into a waste box without touching the base paper.

This device generally uses a claw-like member to lift the front edge of the Ig paper, guide it to a meshing part with a row of vertically opposed feed gears, and feed it into the device by holding it in its mouth. It is generally worn on the body and fed with the ink-covered side facing downward.

However, after printing is finished, the ink is in the form of a thin film that is easily torn and whose durability has deteriorated by σ7. Either the scale comes into contact with the guide plate and gets stuck or torn and does not reach the disposal box, or the scale gets stuck due to interference from the paper that is fed in later, and this causes a thin film to get caught on the teeth of the feed gear and prevent it from rotating. The situational force ζ that can be found from outside arises.

In order to remove all of this, you have to reverse the trap as appropriate and carefully pull it out by hand, so you end up with the opposite result, as if it were designed to keep your hands clean.

In addition, even if the Ryowa is successfully peeled off and sent into the crack, it is difficult to send it to the disposal box due to the stickiness caused by the ink and the fact that it gets caught due to the slanted edge of the base paper fed across its width. If the item is not sent to the waste bin as expected,
This also means that the device is virtually ineffective.

In addition, in the past, the removed raw material was wrapped up in a group and discarded each time, or once this device was installed, it was used for the time being.
The removed base paper will be stored in the disposal box, and it is considered that there may be cases where it is undesirable to use test bushings, management materials, etc. in order to leak confidential information.

The present invention aims to eliminate such drawbacks and provide a reliable base paper removal device, and the gist thereof is that a shredding cutter 50 is disposed in one passage.

The raw paper led to the device head 67 comes into contact with the overlapping portion of the double-legged cutter 50, and is fed into the inside of the device by the rotation thereof, and at the same time is continuously cut into the double-legged cutter 50.

In the present invention, as described above, the base paper to be removed is sequentially shredded, so that the base paper does not fold up due to feeding and exhibit a dense and strong string shape in the direction perpendicular to the feeding direction. The scale should not get entangled with the rotating parts or obstruct the passage of the paper being sent later, or the shredded paper should have appropriate undulations and twists, and should not be fed flatly. In this way, the surface to which the ink is largely applied does not stick to the guide plate or other parts of the device.

Furthermore, since the raw paper is sent out from the narrow 1st corner by the shredding cutters arranged in a row, the ejection force is very strong, and the conveyance and stuffing from the #I shredding cutter to the waste box 61 can be carried out reliably. In addition, since the IQ paper edges 1-1, etc., which are rigid in the direction perpendicular to the feeding direction, are shredded, there is no need to worry about them getting caught in the width direction during conveyance, thereby reducing equipment trouble. You can use the device with peace of mind because you won't have to get your hands dirty or have to worry about restoring the data. In addition, the transportation within the packaging and the packing into the disposal box are extremely reliable, and the removed originals are discarded in small pieces, which is convenient for the machine, all of the above-mentioned drawbacks are overcome. I can do something.

To explain the first embodiment shown in FIG. 1 and FIG.
The base paper selvedge holes 1-2 arranged in rows are inserted into the base paper 1 and the stopper bottle 2, and the base paper is fixedly wound.

In other words, the end edge of the ear portion 1-1 rests on bellows 4 appropriately arranged in the direction of the outer circumferential generatrix of the printing plate 2, and is held slightly raised from the outer peripheral surface of the printing cylinder.

Paper 5, & scissor roller 6, synchronous roller 7-1.7-
The paper is fed by the press roller 8, printed by the press roller 8, and discharged to the right in FIG.

The rotation of the electric motor 9 is appropriately decelerated and transmitted to the intermediate vehicle 11 which is idled around the intermediate shaft 1U.

The intermediate wheels 11 are constantly engaged with the plate body reduction 12, and the plate body 2
Rotate.

On the shaft of the middle Nt shaft 1 [), there are a middle nJj gear 11, a clutch mechanism 16, and an intermediate shaft locket 14 made of iron.
Turn on and off the clutch machine *) 13 by electrical or mechanical means,
If the rotation transmission from the internal gear 11 to the intermediate shaft sprocket 14 is reduced by 1 liter.

From the ladle No. 5U onward, which will be explained next, all base paper removal devices are provided.

A sprocket 56 is fixed to the upper blade shaft 52-1 of the shredding cutter, and is connected by an intermediate shaft sprocket 14 and a roller chain 15 to completely transmit rotation.

Gears 54 are provided on the upper blade shaft 52-1 and the lower blade shaft 52-2, respectively.
-1.54-2 is fixed and meshed, and the rotation of the upper blade shaft 52-1 is completely reversed and transmitted to the lower blade shaft 50-1.50-1
... is the upper blade of the fine H cutter, 50-2.5 [J-2.
... are the lower blades of the shredding cutter, and the upper blade shaft 52-1 respectively
The gears 54-1.5 are arranged in rows on the lower blade shaft 52-2, and alternately form minute gaps on the sides at the outer periphery or form overlapping parts in a state of light contact.
4-2, it is driven to move to the left in FIG. 2 at the overlapping portion.

55 is a release claw for the base paper, and when the solenoid 56 is energized and pulled downward, the bell crank 57 rotates to the left, and the connecting bin 5
8, the peeling claws 55 are moved to the right and arranged in a row on the peeling claw body 59.
Close to the full version. 60-1.6G-2 is a guide plate that smoothes the feeding of the base paper 1 and prevents the blades of the two-legged cutter 50 from clogging, and the portion of the shredding cutter 50 is a punched window that just fits through.

Reference numeral 61 denotes a waste box that stores the removed yAa'' that has completely passed through the thin 111 JI cutter 50 and been discharged, and the side facing the shredder 50 is open.

Since the present invention is configured as described above, when the printing is finished and all of the base paper is to be removed, when the base m removal command button (not shown) is pressed, the plate is removed as shown in FIG. rotates slowly to the left, and at the same time, the clutch mechanism 16 is connected and the upper blade shaft 52-1 rotates to the right. Plate peripheral speed and thinness
! The circumferential speed of the I-cutter overlapping section is approximately the same, or may be slightly deviated due to the peeling of the base paper from the printing plate.

When the plate 2 comes to a predetermined position, this is sensed and the solenoid 56 is energized to attract it, and the bell crank 5
7. Move the peeling claw 55 to the right through the connecting bottle 58 and the peeling claw body 59. The peeling claw 55 enters into the gap B of the base paper edge portion 1-1 which is slightly raised from the outer periphery of the plate 2 by the bellows 4, and removes the base paper edge hole 1-2 from the base paper fixing pin 6.

The raw paper edge portion 1-1 rides on the upper surface of the peeling claw 55, reaches the engagement point of the shredding cutter 50, is bitten and moves to the left, and is successively thinned from the edge portion and discharged.

The peeling claw 55 is pulled to the left in FIG. 2 at an appropriate time after the raw paper edge portion 1-1 reaches the engagement portion of the shredding cutter.

When the original paper is completely stretched to the end and pushed into the waste box by the pushing force of the shredding cutter, the clutch mechanism 16 is depressed and the shredding cutter 50 stops rotating.

Subsequently, plate 2 also stops at a fixed position.

The effects of this embodiment are as described above.

Furthermore, a second embodiment shown in FIGS. 6 and 4 will be described.

The second embodiment corresponds to the case where, in the first embodiment, a pair of upper and lower feed gears are inserted coaxially with the upper and lower blades of the fine H cutters arranged in a row, and mesh with each other. Blade axis 5
The configuration is completely the same as that of the first embodiment except for the parts coaxially assembled to the lower blade shaft 52-1 and the lower blade shaft 52-2.

Gears 54-1, 54-. fixed to the upper blade shaft 52-1 and the lower blade shaft 52-2, respectively. 2 are meshed with each other, and the gears 54
-1.54-2 are the upper blade shaft 52-1 and the lower blade shaft 52, respectively.
-2, they mesh with each other, rotate in opposite directions, and move to the left in FIG. 6 at the meshing portion.

The upper blade shaft 52-1 has upper blades 5o-1, 5o-1, . . . and feed drive gears 51-1, 51-1, . . . arranged in a row, and the lower blade shaft 52-2 has lower blades. Blade 5o-2, 50-2...
The feed driven gear 51-2 is fixedly arranged in a row, and the feed driven gear 51-2 is set so as to be rotatable. The overlapping meshing state of the upper and lower blades is the same as in the first embodiment, and the feed driven gear 51-2 is the same as the feed drive gear 51-2.
1 and rotates as a result.

In the case of the second embodiment, since a feed gear is additionally provided compared to the first embodiment, there is a great advantage in that the front edge of the paper edge portion 1-1 that reaches the entrance of the paper removal device is gripped first. .

Of course, the blades of the Hosono 1 cutter are lined up on both sides of the feed gear, so the base paper 1 that is held in its mouth is immediately shredded, the base paper is folded by the feed, and becomes dense and strong in the direction perpendicular to the feed direction. Since it does not form a string-like shape, there is no need to worry about it getting caught on the tips of the teeth, unlike conventional devices that only have a feed gear.

In the second case of this embodiment, the same effects as those described in ITJ are exhibited.Furthermore, a sixth embodiment shown in FIGS. 5 and 6 will be described.

The sixth embodiment is a case in which a feed gear is provided on the entrance side of the nameplate of the first embodiment.

Fine-1 cutter upper blade shaft 52-1 feed drive gear shaft 62-
Ml-1 has sprockets 56 and 66 fixed thereon, and is connected and driven by an intermediate shaft sprocket 14 and a roller chain 15.

Several feed drive wheels 51-1 are fixed to the feed drive gear shaft 62-1 at appropriate intervals and rotate integrally. Both feed driven wheels 51-2 are freely rotatably supported on the feed driven gear shaft 62-2, and mesh with the feed drive gear 51-1 to rotate as a result.

The feed gear meshing portion moves to the left in FIG. 6, and its speed is approximately the same as the 8th speed of the printing plate.

In FIGS. 5 and 6, the conveyor belt 64 and the blower 65 operate simultaneously with the operation of the removing device.

The conveyor belt moves toward a separately installed waste box (not shown), and the blower blows air over the conveyor belt in the direction of the waste box. Reference numeral 66 denotes a paper piece input port, which has a shape that guides input paper pieces to the meshing portion of the feeding wheel 51.

Other configurations and operations are similar to those of the first embodiment.

The base paper edge portion 1-1 that has reached the entrance of the apparatus is caught by the feed gear 51 and continues into the apparatus.

Next, the base paper edge portion 1-1 reaches the thin cutter 50, but the two shafts are close together so that the paper edge portion is bitten by the cutter. Because they are arranged, small items can be smoothly delivered and received.

The gonorrhea part is also fed in and shredded, but since both the feed gear and the fine FD+ cutter are designed to have almost the same circumferential speed at the meshing part, it will be supported by this movement and will not crumble. Not thin [! , being drawn towards the cutter. Therefore, it will not get caught on the tips of the teeth of the feed gear 51 or get in the way of the paper that is fed later.

The raw material that has passed all the way through the shredding cutter 50 and has been shredded is twisted appropriately and no longer has a flat shape that will stick to the device, so it has the property of being able to fly just by blowing it gently. In this embodiment, a conveyance belt 64 and a blower 65 are used to convey the waste to a waste box installed at a distance from the apparatus.

It goes without saying that it is not always necessary to use the conveyor belt and the blower at the same time. In addition, since this machine has both legs and one function, if a paper piece input port 66 is provided and the paper piece is shaped to lead to a part of the shredding cutter, it is possible to input paper that has failed in printing and shredding it. You can measure the slow bottom.

This embodiment has the advantage that the initial biting of the #Naneru paper introduced into the apparatus entrance is performed more forcefully than the second embodiment.

The effect is the same as above.

Here, the first to sixth embodiments have been described using cylindrical plates, but the present invention can also be applied to a known double-barrel rotary copying machine with exactly the same device configuration.

Furthermore, even if the printing plate is flat, the same effect can be obtained by guiding the edge of the base paper to the inlet of the device and operating it.

In the embodiment, the removing device is driven by a sprocket and a roller chain, but it goes without saying that the removing device can be similarly driven by a gear train or the like.
