Description

  The present invention relates to a cylinder cleaning apparatus that cleans the surface of a printing press cylinder such as a blanket cylinder of an offset printing press, and more particularly to a cleaning cloth winding structure necessary for cylinder cleaning.

Conventionally, as a cylinder cleaning device that cleans blanket cylinders, impression cylinders, etc., a cleaning cloth made of non-woven fabric is allowed to run in contact with the cylinder surface at the pressing part that can be brought into contact with and separated from the cylinder surface. There is known an apparatus that wipes and removes surface dirt by making use of the nip pressure of the pressing portion and the rotation of the cylinder by moving the cylinder in contact with the cylinder surface.

In this type of cylinder cleaning apparatus, a rubber sheet formed in a semi-cylindrical shape is used to uniformly press the cleaning cloth along the cylinder length direction of the target cylinder. A pressure pad for expanding a seat is known, and the pressure pad is fixed to a pad mounting plate along the cylinder body length direction.
However, if the pressure pad has a uniform thickness, there is a problem in that the pressing portion hits the gap of the rotating cylinder and receives an impact, generating an impact sound and vibration. In order to solve this problem, a pressure pad was developed that did not make the thickness of the entire pressure pad, which is a pressing member, uniform, but reduced the thickness of the central part, which is in contact with the cylinder, and increased the thickness of the base part. (Patent Document 1, Patent Document 2).

A pressure pad with a thin base and a thick base that does not equalize the thickness of the entire rubber sheet, which is a pressing member, makes the center receive the impact received from the rotating cylinder. It has an excellent performance of reducing impact sound and vibration by absorbing at the thin part of the part and applying a pressing force at the thick part of the base with increased rigidity.
However, as the cylinder rotates, the base of the pressure pad is pulled in the direction of rotation of the cylinder, and is partially lifted from the pad mounting plate that has been fitted. May be.

  Furthermore, as in Patent Document 1, when a flat rubber plate having both sides thicker and thinner at the center is curved into a horseshoe shape and used as a pressure pad, both ends of the pressure pad are warped upward to form a saddle shape. As a result, the warping of both ends comes into contact with the cylinder surface first, forming a gap without being able to contact the center portion of the pressure pad, and the cylinder surface cannot be pressed uniformly, resulting in unwiping on the cylinder surface. There is a problem.

Such a cylinder cleaning apparatus is provided with a winding roll having a sizing mechanism that is set so as to wind up a cleaning cloth having wiped off the dirt on the cylinder surface with a certain length. In order to wind up a certain length each time, a detection roller for detecting the diameter of the cleaning cloth is pressed against the surface of one end of the winding roll.
However, the other end of the take-up roll has no pressing member and is a free end, so that one end of the take-up roll is wrinkled. As a result, the back surface cannot be used as a cleaning cloth.

  Also, bearings for mounting the cleaning cloth supply roll and the cleaning cloth take-up roll on the cylinder cleaning device are provided on the left and right plates of the cylinder device. In order to mount the roll shaft on this bearing, the holder cover must be moved against the force of the biased spring to expose the notch where the shaft is to be inserted. There is a problem.

  In addition, a so-called wet cloth impregnated with a cleaning liquid is used as a cleaning cloth for cleaning dirt on the cylinder surface, but the impregnated cleaning liquid remains on the cylinder surface, and in order to repel the printing ink to be started next, the cylinder surface Has to be wiped off with a cloth, and there is a problem that the cleaning cost is high because the cleaning cloth uses petroleum materials.

First, an embodiment of a cylinder cleaning device having a cleaning cloth winding structure of the present invention will be described with reference to the accompanying drawings.
A cylinder cleaning device 1 shown in FIGS. 1 to 3 is disposed to face a blanket cylinder 2 to be cleaned. The cylinder cleaning device 1 is detachable and a pair of plates 3 to which a roll of cleaning cloth is attached, 3 and the frames 4 and 4 fixed to the frame of the printing press outside the plate 3 constitute a framework, and one frame 4 is provided with an air cylinder 5 as a pressing means source.
The cylinder cleaning device 1 is rotated about the rotating shaft 6 by the air cylinder 5 and serves to bring the blanket cylinder 2 into contact and separation.

  The pressing portion is provided opposite to the blanket cylinder 2, and as shown in FIG. 3, a pad mounting plate 9 to which a pressure pad 8 as a pressing member is mounted, and a cleaning cloth 13 to guide both ends of the pad mounting plate 9. The guide portions 10a and 10b.

A cleaning cloth supply roll 11 and a cleaning cloth take-up roll 12 are arranged behind the pad mounting plate 9 on the plate 3, and the cleaning cloth 13 is fed out from the cleaning cloth supply roll 11, and pressure is applied from the guide portion 10 a in the drawing. It is wound up by a cleaning cloth winding roll 12 on the rear side through a pad 8 and a guide portion 10b and a cleaning cloth guide roller 14.
The cleaning cloth 13 is wound up by braking the cleaning cloth supply roll 11 to drive the cleaning cloth winding roll 12 intermittently. For this purpose, a fixed dimension feeding mechanism described later is provided. Yes.

Next, the effect | action by the said structure is demonstrated.
The cylinder cleaning device 1 is rotated by the operation of the air cylinder 5 around the rotating shaft 6, moves forward by a predetermined amount toward the blanket cylinder 2, and is supplied from the cleaning cloth supply roll 11 via the pressure pad 8. The cleaning cloth 13 is brought into contact with the blanket cylinder 2 with a predetermined pressing force for wiping and cleaning, and a fixed amount of the cleaning cloth 13 is passed through the cleaning cloth guide roller 14 to the cloth take-up roll 12 by a sizing feeding device (not shown). It is wound up.
After wiping and cleaning, the cylinder cleaning device 1 is moved backward by the operation of the air cylinder 5 and separated from the blanket cylinder 2 to complete the cleaning. Wiping cleaning is performed by repeating this.

  As shown in FIG. 3, the pressure pad 8 at the time of wiping and cleaning increases in thickness as it goes below the base portion 15, so that the pressure pad 8 becomes rigid against an external pressure, and the protruding portion of the locking portion 17. 19 is engaged with the groove 22 of the pad pressing bar 20, and the inwardly inclined side surface 203 of the upper portion 21 strongly presses the base 15 against the side wall of the recess 25, so that the base 15 of the pressure pad 8 accompanying the rotation of the blanket cylinder 2 is obtained. Does not move, and only the central portion 16 is deformed to move up and down as the blanket cylinder 2 rotates.

  Even if a force or impact caused by the rotation of the cylinder is applied to the central portion 16 of the pressure pad 6 due to unevenness caused by the clamping mechanism of the blanket cylinder 2, the base portion is increased in rigidity and fixed to the pad mounting plate 9 as described above. 15 is stable because it is not lifted with rotation, and the central portion 16 simply moves up and down as the blanket cylinder 2 moves, and does not cause undulation in the length direction of the blanket cylinder 2. In addition, the position of the central portion 16 in contact with the cleaning cloth 13 can be stabilized, and the wiping and cleaning performance can be improved by making the nip pressure and the nip width constant.

Hereinafter, a first embodiment of a cleaning cloth winding structure of a cylinder cleaning device according to the present invention will be described.
In the cylinder cleaning apparatus 1 shown in FIG. 1, a mechanism for winding the cleaning cloth 13 that wipes the surface of the blanket cylinder 2 as a cylinder is provided. That is, as shown in FIG. 4, the frame 4 fixed to the frame of the printing press includes a rotary shaft 6 having one end inserted into a holder portion 80 fixed to one side of the frame 4, and the rotary shaft. An air cylinder 5 that swings the cylinder cleaning device 1 around 6 is fixed via a fixing bracket.

  As shown in FIG. 1, a notch is cut in one corner of the frame 4 to provide a stepped portion, and a contact portion 81 is formed on one side of the stepped portion. Further, as clearly shown in FIG. 4, a pair of left and right plates 3, 3 serving as a swinging skeleton of the cylinder cleaning device 1 are installed inside the frames 4, 4 at the other end of the rotating shaft 6. . FIG. 4 shows only the left side of the pair of left and right frames 4 and 4 and the plates 3 and 3.

  A lever (not shown) connected to the plate 3 via a pin 83 is fixed to the tip of the cylinder rod 82 attached to the air cylinder 5.

  The plate 3 has a substantially rectangular flat plate shape, and one side (right side in FIG. 4) of the plate 3 has a cleaning cloth supply roll 11, a cleaning cloth take-up roll 12, and a pressure pad 8 facing the blanket cylinder 2. The other side of the plate 3 is divided into an operation side which is a fixed-size winding mechanism side to which a rotating shaft 6 and a pin 83 are attached and which will be described later.

  On the cleaning work side of the one surface of the plate 3, a cleaning cloth supply roll 11 around which a clean cleaning cloth 13 is wound, and a cleaning cloth take-up winding up the dirty cleaning cloth 13 after the surface of the blanket cylinder 2 is wiped off. A roll 12, a mounting plate 9 on which a pressure pad 8 that presses the cleaning cloth 13 against the surface of the blanket cylinder 2 is fixed, and a diameter detection lever portion 84 that measures the diameter of the wound cleaning cloth 13 are disposed. ing.

  The diameter detection lever portion 84 for measuring the diameter of the cleaning cloth 13 wound up by the cleaning cloth winding roll 12 is fixed to one cleaning work side of the support shaft 85 fitted in the hole formed in the plate 3. An L-shaped arm 86, a rotatable detection roller 87 that contacts the surface of the wound cleaning cloth 13 provided at the tip of the L-shaped arm 86, and the other operating side of the support shaft 85 are fixed to the other operation side. A positioning stopper 88 having a pentagonal shape is provided, and a cylindrical rod 89 erected at the tip of the positioning stopper 88.

  The shaft 12 a of the cleaning cloth take-up roll 12 is fitted with a one-way clutch 90 fitted in a hole formed in the plate 3, and arranged on the operation side of the one-way clutch 90 in parallel with the frame 4. A winding plate 91 is fixed. Further, a coil spring 92 that constantly urges the winding plate 91 counterclockwise in FIG. 1 is provided outside the one-way clutch 90 between the winding plate 91 and the plate 3.

  The winding plate 91 has a substantially rectangular shape as shown in FIG. 6, and a winding lever 94 having a rotatable roller 93 at the tip on the surface on the frame 4 side at the outer one end of the winding plate 91. Is formed, and a U-shaped groove 95 (see FIG. 5) into which the rod 89 erected on the positioning stopper 88 is inserted is defined at the other end of the winding plate 91 to form a U-shaped groove. One notch piece 95 forms a cam portion 96.

  The take-up lever 94 and the roller 93 have such a length that they are in contact with a contact portion 81 provided on the frame 4 when the take-up plate 91 rotates, and the contact portion 81 rotates. The winding lever 94 is received and the rotation of the winding plate 91 is restricted.

  The rod 89 of the diameter detecting lever portion 84 is inserted into the U-shaped groove 95 and comes into contact with the cam portion 96, and the cam portion 96 is elastically applied by the coil spring 92 that urges the winding plate 91 counterclockwise. The rod 89 is pressed in the counterclockwise direction, and this pressing force presses the detection roller 87 of the diameter detection lever portion 84 on the cleaning work side against the surface of the cleaning cloth 13. The rod 89 is released from the U-shaped groove 95 during the operation of winding the cleaning cloth 13 and does not come into contact with the cam portion 96.

  The distance between the roller 93 of the winding lever 94 and the contact portion 81 of the frame 4 when the blanket cylinder 2 is being cleaned is set shorter than the moving distance of the cylinder rod 82.

The operation of the cylinder cleaning device 1 configured as described above will be described.
After the cleaning of the surface of the blanket cylinder 2 in the cleaning cloth pressure contact state of FIG. 1, when the air cylinder 5 is operated and the cylinder rod 82 is moved downward in FIG. Rotating clockwise, the pressure pad 8 releases the pressure contact of the cleaning cloth 13 to the blanket cylinder 2 (FIG. 2).

  By the counterclockwise rotation of the plate 3 about the rotation shaft 6, the winding plate 91 attached to the plate 3 via the one-way clutch 90 is also rotated counterclockwise, and the roller 93 of the winding lever 94 is rotated. The distance of the gap between the frame 4 and the contact portion 81 of the frame 4 is gradually reduced. After a predetermined amount of rotation, the roller 93 of the winding lever 94 erected on the winding plate 91 comes into contact with the surface of the contact portion 81 of the frame 4, and the winding lever 94 further rotates counterclockwise. To stop.

By further rotating the plate 3 counterclockwise by the operation of the cylinder rod 82, the surface of the blanket cylinder 2 is wiped off and the winding of the dirty cleaning cloth 13 onto the winding roll 12 is started. The winding plate 91 that has been rotated in the clockwise direction starts to rotate clockwise from the roller 93 of the winding lever 94 against the force of the coil spring 92, and from the contact portion 81 of the frame 4. Forcibly sinks downward.
2, the rod 89 of the diameter detection lever portion 84 that has been in contact with the cam portion 96 inserted into the U-shaped groove 95 is released from the U-shaped groove 95. .

As a result, the detection roller 87 at the tip of the L-shaped arm 86 connected to the rod 89 spaced apart from the cam portion 96 via the support shaft 85 temporarily receives the elastic force of the coil spring 92 via the cam portion 96. It is released and stays in the open position only by its own weight and leaves the surface of the cleaning cloth 13.
The cleaning cloth 13 that is not pressed by the detection roller 87 is wound up with equal force on the winding surface of the blanket cylinder 2 in the body length direction, to the end of the cleaning cloth by the partial contact of the detection roller 87 as in the prior art. Do not cause the traps. The amount of movement of the winding plate 91 that sinks from the abutting portion 81 of the frame 4 is the fixed feed amount of the cleaning cloth 13.

  The air cylinder 5 is actuated from the state of FIG. 2, and the cylinder rod 82 starts to move upward in FIG. Accordingly, the plate 3 rotates clockwise about the rotation shaft 6. The winding plate 91 sunk below the contact portion 81 of the frame 4 becomes parallel to the contact portion 81 of the frame 4 by the urging force of the coil spring 92 while rotating counterclockwise, and gradually winds. The roller 93 of the taking lever 94 is moved away from the contact portion 81 of the frame 4 of the air cylinder 5. At this time, since the one-way clutch 90 is disposed on the cleaning cloth winding roll 12, the wound cleaning cloth 13 is not fed back.

  When the roller 93 of the winding lever 94 moves away from the contact portion 81, the rod 89 of the diameter detection lever portion 84 that has become free during the fixed-size winding operation causes the U-shaped groove 95 of the winding plate 91. It is reinserted in and comes into contact with the cam portion 96. The rod 89 pressed by the cam portion 96 and applied with the urging force of the coil spring 92 brings the detection roller 87 into contact with the surface of the cleaning cloth 13 of the cleaning cloth winding roll 12 via the L-shaped arm 86 again. Set to the washable state shown in.

  Thus, since the coil spring 92 contracted on the outer surface of the one-way clutch 90 gives an elastic force to contact the cleaning cloth 13 to the diameter detection lever portion 84 via the winding plate 91, the detection lever that has been conventionally required is provided. A spring can be dispensed with in the portion 84.

  Next, as a second embodiment, a cylinder cleaning apparatus 1 using a linear motion method will be described. In addition, about the same site | part as the said 1st Embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

6 to 8 show a second embodiment.
A cylinder cleaning apparatus 1 shown in FIG. 6 is disposed horizontally facing a blanket cylinder 2 pivoted on a frame of a printing machine main body (not shown), and is supported by a column (not shown) on the frame of the printing machine main body. The frame 4 is fixed.

  The frame 4 has a rectangular flat plate shape. For example, an air cylinder 5 that moves to the left and right in parallel with the ground is fixed to one side of the frame 4 via a fixing bracket, and a pair of left and right plates 3 are horizontally mounted on the inner surface of the frame 4. It is supported to move freely.

  A groove 97 having a substantially rectangular recess cut therein is provided inside one corner surface of the frame 4, and a contact portion 98 is formed on one side of the groove 97 opposite to the blanket cylinder 2. . Instead of cutting the groove 97, another member in which the shape of the groove 97 is formed in advance may be attached to the frame 4.

The air cylinder 5 is fixed below the frame 4 in parallel with the ground, and is connected to the plate 3 via a pin 84 attached to the tip of the cylinder rod 83.
By the operation of the cylinder rod 83, the plate 3 moves in the left-right direction in the drawing.

  On the winding plate 91 fixed to the one-way clutch 90 fitted to the shaft 12 a of the cleaning cloth winding roll 12, a winding lever 94 having a rotatable roller 93 is erected, and the other end of the winding plate 91. Further, a U-shaped groove 95 into which the rod 89 of the diameter detection lever portion 84 is inserted is defined, and one notch piece of the U-shaped groove 95 serves as a cam portion 96.

The roller 93 of the winding lever 94 faces into the groove 97 of the frame 4, and the contact portion 98 formed in the groove 97 and the roller 93 abut.
A coil spring 92 that constantly urges the winding plate 91 counterclockwise in FIG. 6 is provided outside the one-way clutch 90 between the winding plate 91 and the plate 3.

  The diameter detection lever portion 84 is the same as the first embodiment in that the diameter detection lever portion 84 includes a rod 89, an L-shaped arm 86, and a detection roller 87 that detects the winding diameter of the cleaning cloth 13.

  In the cleaning cloth pressure contact state of FIG. 6, the coil plate 92 urging the winding plate 91 counterclockwise in FIG. 6 is pushed counterclockwise by the cam portion 96 that also contacts the rod 87 of the diameter detection lever portion 84. Thus, the detection roller 87 of the diameter detection lever portion 84 presses the surface of the cleaning cloth 13 and detects the wound diameter.

  When winding the cleaning cloth 13 around the cleaning cloth winding roll 12, when the air cylinder 5 is operated to extend the cylinder rod 82 to the left side in the figure, the plate 3 moves to the left as shown in FIG. The cleaning cloth 13 is moved away from the body 2.

  Then, the roller 93 of the winding lever 94 comes into contact with a contact portion 98 formed in the groove 97. The winding plate 91 starts to rotate clockwise from the counterclockwise direction against the elastic force of the coil spring 92 with the roller 93 as a fulcrum, and the rod 89 that is in contact with the cam portion 96 of the U-shaped groove 95 The character-shaped groove 95 is released.

  As a result, the detection roller 87 at the tip of the L-shaped arm 86 that is temporarily released from the elastic force of the coil spring 92 and hangs down by its own weight is separated from the surface of the cleaning cloth 13.

  The cleaning cloth 13 that is not pressed by the detection roller 87 is wound with a uniform force on the winding surface of the blanket cylinder 702 in the cylinder length direction. It does not cause the trap to.

  It should be noted that the illustrated embodiment is merely an example, and is not a description to limit the technical scope of the present invention.
