It is a thing.

[0002]

2. Description of the Related Art Generally, a rotary type stencil printing machine is provided with a cylindrical plate cylinder and an ink supply means is provided inside the plate cylinder. Further, the stencil sheet can be wound around the outer peripheral surface of the plate cylinder formed of the ink permeable material. Then, the plate cylinder is rotated, and the printing paper is sandwiched between the printing roller and the press roller and conveyed, whereby printing is performed on the paper.

The base paper wound around the plate cylinder is discarded as a discharged plate after use. As this discharged plate collecting device, a device shown in Japanese Patent No. 2866146 has been proposed.

When the compression plate reaches the lower limit, a downward pulling force is applied to the compression plate.

Further, when the plate discharge is discharged into the plate discharge box,
The compression plate in the ascending limit is moved downward so that it is pulled by the cord body by the arm that moves downward, and the discharged plate stored in the plate discharge box is compressed. At this time, the cord body exerts a downward pulling force on the compression plate even when the compression plate reaches the lower limit. After the compression, the compression plate is moved upward with the receiving member supported and supported by the arm that moves upward, and then moved to the original upper limit. In this way, the second and subsequent plates are sequentially compressed and stored.

As shown in FIG. 1, a plate discharge transfer mechanism 50 is provided so as to be located between the plate discharge container 22 and the plate cylinder 12. The plate discharge transfer mechanism 50 includes a drive shaft 5 and a driven shaft 5.
Drive and driven pulleys 53,5 mounted on 1,52
4 and belts 57 and 58 mounted on driving and driven pulleys 53 'and 54' supported by support shafts 55 and 56.

As shown in FIG. 1, a detected element 63 is attached to the outer peripheral surface of the rotary support shaft 30. A first detector S1 is attached to a predetermined position of the support frame 21 via a bracket 61 so as to correspond to the detected element 63. The first detector S1 is a drive arm 4
Two rotational positions of 7, that is, a position corresponding to the lower limit or the upper limit of the cover plate 24 is detected. By inputting the detection signal of the first detector S1 to the control device C, the operating mechanism K2
ON / OFF control of. As shown in FIG. 2, a detection target 36 is provided at the base end portion of the tilt lever 29, and a second detector S2 is provided at a predetermined position on the outer surface of the side plate 21a corresponding to the detection target 36. It is installed. The second detector S2 detects two rotational positions of the tilt lever 29, that is, the actual lower limit or upper limit of the cover plate 24.

As shown in FIG. 2, the motor 41 is on / off controlled by an operation signal from the controller C. Further, the control device C is provided with a computer so as to control various operations of the stencil printing apparatus 11, and controls various operations described below.

Next, the operation of the plate discharge collecting apparatus configured as described above will be described. 1 and 2 show a state in which the cover plate 24 is held at the lower limit. When the stencil sheet 13 wound around the outer peripheral surface of the plate cylinder 12 has been used up, based on a start signal output from the controller C when the operator's instruction or the printing work of the preset number of prints is completed. The plate discharge collection work is started. That is, the motor 41 is driven based on the start signal from the control device C, and the cover plate 24 is lifted up and moved to the upper limit. Further, the locked state of the plate discharge 13a by the locking device 14 is released.
Next, the plate cylinder 12 is rotated counterclockwise in FIG. 1, and the pair of upper and lower belts 5 of the plate discharge transfer mechanism 50 is rotated.
The leading edge of the plate discharge 13a is inserted between 7, 58. Therefore, the plate discharge 13a is transferred to the plate discharge container 2 by the plate transfer mechanism 50.
2 and is accommodated in the bottom of the plate discharge container 22.

When the recovery operation of the first plate discharge 13a is completed, an end signal is output from the controller C, the motor 41 of the elevating mechanism 25 is rotationally driven in the reverse direction, and the cover plate 24 is moved from the ascending end to the descending end. And the discharge plate 13a is compressed by the cover plate 24. The lid plate 24 is held at this lower limit.

FIG. 4 shows one plate 13a in the plate discharge container 22.
Is accommodated and the lid plate 24 is lowered to the intermediate height 1. FIG. 5 shows the state of the lifting mechanism 25 in FIG.
When the collecting operation of the plate discharge 13a described above is similarly repeated a plurality of times, the plate discharge container 13a in the plate discharge container 22 becomes full. Then, as shown in FIG. 6, the compression reaction force received from the discharge plate 13a in a state where the cover plate 24 is lowered to the intermediate height position is larger than that in the state in which the discharge plate 13a is small as shown in FIG. Therefore, the operation of the tilt lever 29 and the cover plate 24 is delayed compared to the operation of the drive arm 47 of the elevating mechanism 25. More specifically, the rotation of the drive arm 47 by the actuating mechanism K2 is performed at a predetermined speed, the number of the discharged plates 13a accommodated in the plate discharge container 22 increases, and the reaction force when the cover plate 24 compresses the discharged plates 13a. Becomes larger, the compression reaction force becomes larger than the biasing force of the spring 32, and the tilt lever 29
The rotation speed of is lower than the rotation speed of the drive arm 47.

When the delay time of the above operation is measured by the detection signals from the first detector S1 and the second detector S2 and the control device C, it is detected that the discharge plate 13a is full as follows. It That is, FIG. 9 shows the drive arm 47, the cover plate 24, and the first detector S in each plate discharge collecting operation.
The operation of the first and second detectors S2 is shown. The time tu until the drive arm 47 and the cover plate 24 are in the lower limit and moved from there to the upper limit is the same each time. The time required for each drive arm 47 to move from the position corresponding to the rising limit of the cover plate 24 to the position corresponding to the lower limit thereof is the motor 41.
Since the rotation speed of the first detector S is controlled to be constant, the first detector S
1 is detected as the same time tc.

On the other hand, the time detected by the second detector S2, that is, the time t1 to tn from the time when the cover plate 24 is moved from the ascending limit to the descending limit is gradually increased as the number of discharged plates 13a increases. become longer. Then, these delay times t1
When -tc, t2-tc, t3-tc, and tn-tc reach a preset set time ts, it is determined that the plate discharge 13a in the plate discharge container 22 is full, and the controller C detects a full detection signal. Is output and the indicator lamp is turned on and the buzzer is activated.

The motor 41 of the elevating mechanism 25 is driven based on this full detection signal, and the cover plate 24 is stopped and moved to the upper limit shown in FIGS. As a result, the plate discharge container 22 is removed from the support frame 21 by the operator, and a predetermined number of the plate discharge plates 13 a accommodated in the plate discharge container 22 are discarded.

Next, the effects of the plate discharge collecting apparatus of the above embodiment will be described together with the configuration. (1) In the above-described embodiment, the cover plate 24 for opening and closing the plate discharge container 22 is opened upward only during the collecting operation of the plate discharge container 13a to the plate discharge container 22, and the cover plate 24 is always at a predetermined height at which the plate discharge plate 13a can be compressed. It is configured to be held in a position (for example, the lower limit). Therefore, the plate discharge 13a collected in the plate discharge container 22
Can be held in a compressed state, and troubles during the recovery work of the discharged plate due to the upward swelling of the discharged plate 13a can be prevented. Further, the plate discharge container 22 of the plate discharge 13a
It is possible to store up to the set number of sheets for
It is possible to eliminate unevenness in the number of discharged plates.

(2) In the above embodiment, the first detector S1
And when the delay time (tn-tc) detected by the second detector S2 and the control device C reaches a preset set time (ts), the discharge plate 13a in the plate discharge container 22 becomes full. I decided to inform it. For this reason, it is possible to reliably detect that the specified number of plate discharges 13a are full when the plate is accommodated.

(3) In the above embodiment, the rotation support shaft 30.
The lid plate 24 is moved up and down by the tilting lever 29 via the up-and-down support member 26 and the connecting piece 27.
Further, the drive arm 47 is rotatably supported around the rotation support shaft 30, and the tilt lever 29 and the drive arm 47 are linked by the spring 32. Therefore, the compression operation of the plate discharge 13a by the cover plate 24 can be smoothly performed. (Modification) The above embodiment may be modified and embodied as follows.

The first detector S1 and the second detector S2
The function of may be set as shown in FIG. The time tu from when the drive arm 47 is in the lower limit to when it is moved to the upper limit is the same time each time as the time described in FIG. The time until each drive arm 47 is moved from the position corresponding to the rising limit of the lid plate 24 to the position corresponding to the lowering limit is the same time tc by the first detector S1 as the time described in FIG. To be detected.

On the other hand, the second detector S2 has a tilt lever 29.
In order not to detect the lower limit and the upper limit of the (cover plate 24),
Moreover, it is set so as to detect a predetermined intermediate position of the tilt lever 29 (cover plate 24). That is, while the drive arm 47 is moved from the lower limit to the upper limit, the second detector S2 detects the intermediate predetermined position of the tilt lever 29.
Further, the second predetermined detector S2 again detects the predetermined intermediate position of the tilting lever 29 until the drive arm 47 is moved from the ascending limit to the descending limit. And the drive arm 47
The time tf1 to tfn from the start of descending from the ascending limit to the detection of the intermediate predetermined position of the tilting lever 29 by the second detector S2 becomes gradually longer as the number of discharged plates 13a increases. When the time tfn reaches a preset time ts', the plate discharge 13a in the plate discharge container 22 is discharged.
Is determined to be full, the control device C outputs a full detection signal, and the display lamp is turned on and the buzzer is operated.

In the above-described embodiment, the plate discharge container 22 is configured to be separable from the support frame 21 by itself, but it is embodied in a plate discharge collecting device having a structure in which the lid plate 24 and the lifting mechanism 25 are attached to the plate discharge container 22.
