Description

[Detailed description of the invention] (Technical field) This invention is based on a plate discharging device of a mimeograph printing machine, more specifically, a pair of plate discharging rollers arranged around the outer periphery of the printing drum. This relates to a device that grips and discharges to the outside.

(Prior Art) For example, in a rotary mimeograph printing machine, the work of manually peeling off used base paper from the printing drum has the disadvantage that hands and clothes are inevitably stained because the base paper is covered with ink. In order to eliminate this problem, a plate disposal box is installed on a special table below the printing machine, and the base paper peeled from the printing drum is held between a pair of plate discharge rollers and ejected, and then disposed of into the plate disposal box. has been proposed. However, the above-mentioned plate discharge box system has the disadvantage that when the paper discharge path between the plate discharge roller and the plate discharge box becomes long, it is extremely difficult to discharge the paper from the plate discharge roller to the plate discharge box without any trouble. .

(Purpose) This invention eliminates the drawbacks of the conventional methods described above, and makes it possible to securely store the used base paper peeled off from the printing drum in a bag without causing any trouble after being discharged from the plate discharge roller. The purpose of the present invention is to provide a plate discharging device that is easy to dispose of.

(Structure) In order to achieve the above object, this invention accommodates the mimeograph paper discharged by the discharge roller, and is made of a flexible material that does not allow ink to pass through and comes into close contact with the base paper, and is made of a flexible material. a bag-shaped container having an engaging portion that can be engaged with each other; and an outlet of the plate discharge roller, one end of which is disposed close to the outer circumferential surface of the roller, and the container is opened. and a pair of plate-like bodies provided with an engaging portion that can be removably engaged with the engaging portion in the state.

Hereinafter, a concrete explanation will be given based on one embodiment of this invention.

1 and 2 show a first embodiment. In the drawings, 1 is a printing drum, and a pair of discharge rollers 5 and 6 are arranged around the outer periphery of the drum 1 so as to be rotatable in the direction of the arrow. The plate discharge rollers 5 and 6 each include a plurality of roller bodies 5a to 5d and 6a to 6d fixed at predetermined intervals on rotating shafts 7 and 8, respectively. Rotating shaft 8
is a peeling claw 9 that peels off the base paper M from the printing drum 1.
is pivoted. In front of the paper exit of the discharge rollers 5, 6, there is a pair of guide plates 10, 1 for guiding the paper that is pinched and discharged by the rollers 5, 6.
1 are arranged vertically at a predetermined interval between the rotating shafts 7 and 8. At one end of the guide plates 10 and 11, notch holes 13 and 14 are formed to have a size in which the roller bodies 5a to 5d and 6a to 6d are partially fitted. Reference numeral 16 denotes a vinyl bag body having an opening 17 at one end and containing used base paper, and a locking tool 18 is attached to the inner surface of the opening 17 of this bag body 16 so as to face each other so as to be engageable. ing. Guide plates 10, 11
A locking tool 19 similar to that described above is also provided on the outward facing surface of the other end.
are correspondingly attached to the locking device 19, and the locking device 1 is attached to the locking device 19.
Opening 1 of bag body 16 by engaging 8
7 can be detachably attached to the guide plates 10 and 11. Incidentally, as the fastener, magic tape (registered trademark), double-sided tape, a hook (button), or the like may be used. 21 is a support stand that supports the bag body 16.

In the above configuration, the plate discharge rollers 5 and 6 are rotated in the direction of the arrow by a driving member (not shown), and the peeling claw 9 is swung by an operating member (not shown) so that its tip approaches the outer peripheral surface of the printing drum 1. first
As shown in the figure. As described above, the base paper M on the outer peripheral surface of the printing drum 1 is peeled off by the peeling claw 9,
The leading end of the plate is held between the discharge rollers 5 and 6 and discharged. The original paper discharged from the plate discharge rollers 5 and 6 is guided by guide plates 10 and 11, and then stored in a bag body 16. At this time, even if the discharged base paper tries to wrap around the discharge rollers 5 and 6,
The guide plates 10 and 11 reliably prevent the winding. By repeating the above operations, when a large number of used base papers are stored in the bag body 16, the locking tool 18 attached to the opening 17 of the bag body 16 is fixed to the locking device attached to the guide plates 10, 11. Ingredients 19
The bag body 16 is removed from the bag body 16, and the locking tools 18 of the opening 17 of the bag body 16 are engaged with each other to close the opening 17, and then thrown away. Then, a new similar bag body is separately attached to the guide plates 10 and 11. Therefore, there is no need to get your hands or clothes dirty with used ink-covered base paper.

3 and 4 show a second embodiment. Since this embodiment is similar to the first embodiment in many parts, similar parts are indicated by the same reference numerals plus 10, and detailed explanation thereof will be omitted. In this embodiment, the plate discharge roller 16 can swing around the rotational axis of the plate discharge roller 15 between a solid line position where it contacts the outer peripheral surface of the printing drum 1 and a chain line position which is further away from the solid line position, using an operating member such as a solenoid (not shown). It's summery. 20 and 21 are connected to the rollers 15 and 1 via arms provided at the ends of both rollers 15 and 16, for example.
A pair of guide plates that can be pivoted as the roller 16 swings by the actuating member without changing the corresponding position with respect to the guide plate 6. A transport space 25 is formed in which the distance between the guide plate 21 and the guide plate 21 is gradually narrowed toward the front end on the bag body side. Transport space 25
The interval between the front end outlets is such that the base paper discharged by the guide plates 20 and 21 can be compressed, and although it is temporarily stopped at this narrow front end exit, it can be pushed out from the outlet by the next discharged base paper. It can be set to any size.

In the above configuration, the plate discharge roller 16 is swung toward the printing drum 11 by the actuating member so as to come into contact with the outer circumferential surface of the printing drum 11, and is rotated in the direction of the arrow by the not-illustrated driving member to achieve the state shown in FIG. 3. At this time, the guide plates 20 and 21 similarly swing. Due to the above, the base paper M on the outer peripheral surface of the printing drum 11
is rolled up from its tip by the plate discharge roller 16 rotating in the opposite direction to the drum 11, and is sandwiched between the plate discharge roller 15 and the plate discharge roller 15. After nipping the base paper, the roller 16 swings in a direction away from the printing drum 11, resulting in the state shown in FIG. 4. The base paper that is pinched and discharged by the discharge rollers 15 and 16 is guided by guide plates 20 and 21, and then
Although accommodated in the bag body 26, the guide plate 20,
When passing through the conveyance space 25 formed by 21,
The leading edge of the base paper hits the front end of the guide plate 20 and is bent, then changes direction and hits the front end of the guide plate 21 and is bent, and by repeating this bending, it becomes a compressed mass M'. and stops near its front end exit.

The lump M' of base paper that has stopped near the front end exit of the guide plates 20, 21 is removed when the subsequent base paper to be discharged when storing used base paper is conveyed while being compressed into a lump in the same manner as described above. , and is extruded by the pressing force of the base paper and housed in the bag body 26. In this way, the used base paper is transferred to the guide plate 2.
Since the raw paper is once compressed to a mass between 0.0 and 21 and then extruded by the subsequent base paper and stored in the bag, the efficiency of storing the base paper in the bag 26 is increased. Other operations are similar to those in the first embodiment, so their explanation will be omitted to avoid duplication.

(Effects) After the used base paper peeled off from the drum is discharged from the plate discharge roller, it can be reliably stored in a bag-shaped container attached to the guide plate. Moreover, once the container has contained a certain amount, the container can be transferred to the guide plate. It can be removed from the container, disposed of, and easily replaced with a new container. In addition, there is no risk of getting your hands or clothes dirty with ink, etc. during the above-mentioned work, and you can dispose of used base paper and replace it extremely efficiently. It has excellent effects such as being easy to use.
