Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an original processing apparatus for compressing and disposing of a sheet-like original. For example, the present invention can be used to compress and process used stencil paper discharged from a stencil printing machine.

[Prior Art] FIG. 12 is a perspective view showing a stencil paper discharge device installed in a stencil printing apparatus. In the figure, numeral 1 indicates a stencil paper storage box, and the stencil paper storage box 1 has a stencil paper intake port 2 on the front side and a stencil paper discharge port 3 on the -side surface.

At the stencil paper intake port 2 of the stencil paper storage box 1, a drive shaft 5 carrying several gears 4 and a rubber roller 6 are provided, respectively, in parallel to the axis of the plate cylinder (not shown). The rubber roller 6 is engaged with the rubber roller 6, and the drive@5 is rotated counterclockwise in the figure by an electric motor (not shown), thereby moving the used stencil sheet S removed from the plate cylinder. It is designed to be carried into a stencil paper storage box 1.

A pair of metal rollers 7 and a rubber roller 8 are provided at the stencil paper discharge port 3 of the stencil paper storage box l, each extending in a direction perpendicular to the axis of the plate cylinder. The metal roller 7 and the rubber roller 8 are engaged with each other to discharge the stencil paper stored in the stencil paper storage box 1 out of the storage box.

At the bottom of the stencil paper storage box 1, a plurality of metal driven feed rollers 10 are arranged at small intervals from each other so as to be parallel to the metal roller rough and the rubber roller 8. Each driven feed roller 10 is rotatably provided around an axis by each shaft 11 .

A driving feed roller 14 is provided on the upper part (ceiling part) of the stencil paper storage box 1 so as to be rotatable around the axis by a shaft 13 parallel to the shaft 11, and is rotated clockwise in the figure by an electric motor (not shown). It is designed to be rotationally driven in the direction.

The drive feed roller 14 has a semi-cylindrical shape with approximately half of its circumference removed, that is, a semicylindrical shape. The remaining peripheral surface of the semi-cylindrical portion is made of an elastic member 15 that has elasticity like a sponge or foamed synthetic resin and has a high surface friction coefficient. In the conventional example shown in FIG. 1, this driving feed roller 14 is divided into two parts in the axial direction, and has a gap 16 in the central part in the axial direction. Two openings 17 are provided in the ceiling wall of the stencil paper storage box 1 to receive the driven feed rollers 14, respectively. A bridge 18 is provided between the two openings 17 and 17 by the ceiling wall left between the two openings 17 and 17 to prevent the stencil paper from wrapping around the circumferential surface of the drive feed roller 14. It has become.

When the drive feed roller 14 is in a rotational position where the side from which the peripheral portion has been removed faces the driven feed roller 10, the drive feed roller 14 has a gap between it and the driven feed roller 10 in the stencil paper storage box 1 to receive the stencil paper. ing. On the other hand, as shown in the figure, when the remaining peripheral portion, that is, the elastic member 15 is in the rotational position facing the driven feed roller 10, the elastic member 15 presses into engagement with the driven feed roller 10. It has become.

A disposal box 19 extending downward from the tray is connected and communicated with the stencil paper discharge D3.

In the above configuration, the stencil paper S removed from the printing plate (not shown) is carried into the stencil paper storage box 1 by the gear 4 and the rubber roller 6. The stencil paper S carried into the stencil paper storage box 1 is stored in the storage box 1 after being folded into a waveform in the vertical direction, as its movement is restricted by the wall surface of the storage box. At this time, the driving feed roller 14 is moved to the driven feed roller 14 on the removed side of its circumferential portion. 0 and creates a gap between the driven feed roller 10 and the stencil paper S to receive the stencil paper S, so that the stencil paper S is carried into the stencil paper storage box 1 without being obstructed by the drive feed roller 14, - section is inserted between the driven feed roller 10 and the driving feed roller 14.

When all of the stencil sheets S are carried into the stencil sheet storage box 1, the driving feed roller 14 is driven to rotate clockwise in the figure. As a result, the elastic member 1 of the driving feed roller 14
5 rotates while being pressed by the driven feed roller 1°.

The stencil paper S between the driven feed roller 10 and the driving feed roller 14 is compressed and becomes a superposed state, and while being folded in the vertical direction, due to PJp5 resistance with the elastic member 15, the stencil paper S is moved inside the stencil paper storage box 1 to the stencil paper discharge port. It is transported towards 3.

The stencil paper S, which has been compressed and folded in a polymerized state, becomes relatively hard due to the folding and polymerization, is sandwiched between the metal roller 7 and the rubber roller 8, and is discharged from the stencil paper discharge 03 into the disposal box 19. .

[Problems to be Solved by the Invention] Although the stencil discharged by the official is folded into the disposal box 19 by the stencil discharge device described above, it is quite bulky. Therefore, it is not possible to store a large amount of waste plates simply by dropping them into the waste box 19. There was a problem that 9 became full quickly.

[Means for Solving the Problems] The original plate processing device of the present invention includes a storage body into which the deodorized original plate is put, and is provided in the storage body so as to be movable up and down, and the area of the pressing part is small when ascending and is small when descending. It is characterized by comprising a pressing body for the original which becomes larger, and means for moving the pressing body up and down.

Further, the original plate processing apparatus may be provided with a pressure detection means for detecting the compression pressure of the original plate by the pressing body.

[Operation] The original plate placed in the storage body is compressed within the storage body by the pressing body lowered by the elevating means. Since the area of the pressing part of the pressing body during descent is large, the above-mentioned compression effect is reliable. When the pressing body rises after compression, the area of the pressing portion of the pressing body becomes small, so that it does not obstruct the conveyance of used originals that are sent one after another. Further, if pressure detection means is provided to detect the compression pressure of the original by the pressing body, the original can be appropriately compressed by lowering the pressing body.

[Example] A first example of the present invention will be described with reference to FIGS. 1 to 6.

The original processing device of this embodiment is a device provided in a 5-stencil printing device, and is used to compress and compactly store used stencil paper discharged from the discharge device of the stencil printing device.

Note that the duct 22. A vertical slit 28 is provided on one side of the plate discharge box 24 and the paper box 27.

Next, inside the duct 22 and the plate discharge box 24, a pressing body 29 is provided so as to be movable up and down. The pressing body 29, which presses the discharged plates placed in the paper box 27, has an opening/closing plate 30 as a pressing part in which an elevating plate 31 and a swinging plate 32, which are almost identical in shape, are hinged together. The opening/closing plate 30 has a square shape that matches the inner shape of the duct 22 and the paper 'A27. A motor 33 is provided on the second surface of the elevating plate 31, and a disc 34 is attached to the drive shaft of the motor 33. Further, a bracket 35 is provided on the upper surface of the swing plate 32. The side portion of the disc 34 and the bracket 35 are interlocked and connected by a link 36 of a bottle connection. That is, the swing plate 32 is configured to swing in the E direction from the horizontal position shown in FIG. 1 by driving the motor 33. In addition, 37 in the figure is the duct 2
This is a sponge that serves as a member that adheres to the inner surface of the paper box 27. Further, as shown in FIGS. 1 and 5(a), pressure sensors 38 are provided at the four corners of the opening/closing plate 30.
It is possible to detect the pressure when compressing the discharged plate. As shown in FIG. 5(b), instead of the pressure sensor 38, a spring bamboo material 39 is provided on the back side of the opening/closing plate 30, and the pressure switch 40 provided on the front side of the opening/closing plate 30 is operated by this spring bamboo material 39. It is also possible to do so. and,
Said duct 22.・The opening/closing plate 30
The elevating plate 31 is connected to elevating means 50, which will be described next.

The elevating and lowering means 50 includes an elevating body 51 connected to the opening/closing plate 30 and a guide case 52 that guides the elevating body 51 up and down. First, as shown in FIGS. 1 to 3, a guide case 52 is provided on the side of the duct 22 where the slit 28 is formed, and is secured to the main body 2o of the stencil printing apparatus. Guide slits 53 and 54 are provided on the curved plate 52a and the rear plate 52b of the +' case 52, respectively. 54 B41+
, = are provided with guide slits 53 and 54, and a rack 55 is provided in the ) row. Next, an elevating body 51 is provided inside the guide case 52. Two hair ring members 56 are provided on each side of the y-lowering body 51,
This bearing member 56 is
3.54 is rotatably engaged. And the ascending kidney body 51
A motor 57 is installed at G-J, and a pinion 58 provided on the drive shaft of the motor 57 meshes with the rack 55. That is, by driving the motor 57, the elevating body 5
1 is configured to be guided by guide slits 53 and 54 of a guide case 52 so that it can freely move up and down.

Next, position detection switches US, MS, and DS for detecting the position of the elevating body 51 are provided in the guide case 520F section and the lower part shown in FIG. 2, and in the middle therebetween. Each of these switches US, MS.

Signals from the pressure sensor 38 provided on the DS and the opening/closing plate 30 are manually input to the first control stage (not shown), and the device is controlled based on this information and operation commands from the outside. It has become so. Particularly, in this embodiment, when the pressure sensor 38 detects a predetermined pressure when the pressing body 29 is lowered, the lowering of the pressing body 29 is stopped, and the pressing body 29 is moved to a standby position above the duct 22. It is designed to be raised to a position where the detection switch US detects it. Further, when the pressure sensor 38 detects a predetermined pressure when the pressing body 29 is lowered, the pressure is lowered than the signal from the position detection switch MS provided in the middle, the pressure body 29 is similarly turned upward and the inside of the paper box 27 is It is designed to display on the operation panel, etc., when the plate is full due to discharge. Further, the position detection switch DS provided in the first part detects the lower limit when the number of discharge plates is low, and even if there is no detection by the pressure sensor 38, the pressing body 29 can be moved upward by the detection by this switch DS. It will be done. No. 13 from the position detection switch MS provided in the middle is ignored when the pressing body 29 is raised, and is inputted before the signal from the pressure sensor 38 when the pressing body 29 is lowered. Controlled to transition to normal operation. These position detection switches US, MS, DS and the pressure sensor 38 define a standby/conveyance zone Z1 between the switches US and MS, and a compressed accommodation zone Z2 between the switches MS and DS.

Next, the operation of the configuration 1- below will be explained.

The push RF body 29 is set at a standby position in the upper part of the duct 22. When used stencil paper (U# plate) is fed into the duct from the feed roller 21, the elevating body 51 starts to descend by the drive of the motor 57, and the pressing body 29 connected to the elevating body 51 also moves into the duct 22. Begins to descend inside. At this time, the swing plate 32 is set in the same plane as the L1 & plate 31. That is, the area of the opening/closing plate 30 is maximized, and the entire surface of the opening/closing plate 30 reliably compresses the waste plate and pushes it into the -F direction within the paper box 27.

When compression is performed at a predetermined appropriate pressure and the surface pressure sensor 38 detects the predetermined pressure, the elevating body 5
1 changes from descending to ascending, and sets the pressing body 29 to the standby position again. In addition, in the pressing body 29 which is rising,
The motor 33 is driven to lift the swing plate 32 of the opening/closing plate 30 in the L direction, thereby reducing the area of the opening/closing plate 30. Therefore, even if discharged plates are continuously thrown into the duct 22 from the feed roller 21, they will not be prevented from falling into the paper box 27 of the discharged plate box 24. Therefore, regardless of whether or not the pressing body 29 is in the plate disposal box 24 below the duct 22, the stencil printing apparatus can be operated continuously to discharge plates one after another.

When the paper 's27 is completely exhausted by discharge, a detection signal of a predetermined pressure by the pressure sensor 38 and a position signal indicating that the opening/closing plate 30 is at the upper limit position of the compression accommodation section Z2 are manually input to the control means, and both By ANDing the signals, it is detected that the paper box 27 is full and displayed on the operation panel or the like.

As shown in FIG. 6, the plate discharge box 2 is magnetically attached to the main body 20.
4 to one side and tilt it, the paper box 2 inside the plate disposal box 24 will be removed.
7 is carried by the bottom plate 26 and protrudes outside from the upper end of the opening of the plate discharge box 24. That is, the upper end of the paper box 27 is inclined toward the operator and protrudes upward, making it easier to take out the paper box.

The paper box 27 filled with discharged plates can be removed and thrown away.

In the first embodiment described above, the elevating body 51 having the motor 57 moves up and down, thereby driving the opening/closing plate 30 up and down. A single stage of elevating and lowering, such as an elevator, in which the opening/closing plate 30 is lowered by -L may be used. Further, the opening/closing plate 30 of this embodiment has a configuration in which the swing plate 32 rotates about a hinge with respect to the fifth elevation plate 31. However, the configuration in which the area of the plate-shaped pressing portion is changed is not limited to the above. For example, a sliding type opening/closing plate provided with a sliding plate that moves linearly with respect to the elevating plate 31 may be used as the pressing part of the pressing body, or the opening/closing plate 30 may be used as a single plate and rotated as a whole. . Further, instead of using the pressure sensor 38, a method of detecting a change in the current value of the motor 57 may be used.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. Here, the main parts, the elevating means and the pressing body, will be explained. The other parts can have almost the same configuration as the first embodiment.

The elevating and lowering means 60 provided in the original processing apparatus of this embodiment includes a drive shaft 61 that is rotationally driven by a drive source (not shown).
and a lift I11 member 63 provided to the drive shaft 61 via a slip clutch 62. Next, a pressing body 65 is provided on the elevating member 63 via a hollow connecting rod 64 . First, the connecting rod 64 is provided with a cylindrical base 66 whose bottom surface is open. A flexible member 4467 is suspended by a wire 69 via a pulley 68 inside the base 66 . This flexible member 67 is provided with four rods 70 so as to form the ridgeline of a quadrangular pyramid, the meshure 1 is stretched on the rods 70, and the sponge 7 is attached to the lower periphery of the rods 70.
2 is provided to form a warrant pressing portion 73. The wire 69 suspending the flexible member 67 of the pressing portion 73 is wound around the slip clutch 62 via the connecting rod 64.

In the configuration north of this point, the drive shaft 61 rotates and the elevating member 6
3 and the pressing part 73 of the pressing body 65 descend, the wire 69 is not caught in the slip clutch 62 and the suppressing part 7
3 opens into a square bell shape. On the contrary, the elevating member 63 and the pressing part 7
3 rises, the wire 69 is connected to the slip clutch 6.
2 and the flexible member 67 enters into the F direction within the base portion 66.

As a result, each bar 70 contacts the lower edge of the opening of the base 66 and is narrowed. In this way, when descending to compress the discharged master, the pressing portion 73 expands and the area increases, and when it ascends, the area decreases, so that the conveyance of the discharged master is not obstructed.

Next, a third embodiment of the present invention will be described with reference to FIGS. 9 to 11. Here, the main parts, the elevating means and the pressing body, will be explained. The other parts of the second embodiment can have almost the same configuration as the first embodiment.

Although not shown in the UA, the elevating means of this embodiment is an air cylinder provided on the F side of the cylindrical storage body 80. At the tip of the air cylinder rod, there is a telescoping multi-stage cylinder 81.
An airbag 82 as a pressing body is provided via the airbag 82 . This air bag 82 communicates with an air cylinder via the multistage cylinder 81 and the rod, and is supplied with air. Further, a weight 83 is provided at the inner bottom of the airbag 82, and a sponge 84 is provided at the outer periphery.

In the above configuration, when air is forced in to compress the discharged plate, as shown in FIG. 11, the air bag 82 expands laterally due to the introduction of air and becomes a rotating solid state, and the area of the pressing part expands. At the same time, the cylinder 81 is sequentially extended downward by air pressure. Further, when suction is applied, the airbag 82 returns to its longitudinally elongated shape as shown in FIG. 10, and at the same time the area of the pressing portion is reduced, the air inside the cylinder 81 is also sucked and contracted. This embodiment also provides the same effects as those of the embodiments described above. In this embodiment, the pressing body was deformed by introducing air, but liquid may also be used.

[Effects of the Invention] According to the original plate processing device of the present invention, the area of the pressing part increases when descending to compress the original, and decreases when ascending, thereby hindering the conveyance of used originals that are sent one after another. It can be reliably compressed and stored in a container without any damage. As a result, a large amount of glue plates can be continuously stored without any transport errors, which has the effect of significantly shortening the continuous use time of the printing press.
