2. Description of the Related Art The surface of a cylinder or the like is required to be clean enough not to deteriorate the quality of objects handled by the apparatus. For example, in the case of a blanket cylinder of a printing machine, when printing is continued for a certain period of time, ink remains on the blanket and accumulates on the blanket, resulting in stains. Therefore, a cylinder cleaning device for cleaning the surface of the blanket has been developed. In a typical cylinder cleaning device, the shafts of the cloth supply roll and the cloth winding roll are rotatably supported by a pair of side plates in parallel with the cylinder axis center line. Both ends of a belt-shaped cleaning cloth are wound around these shafts, and a predetermined tension is applied thereto. On the back side of the cleaning cloth located between the cloth supply roll and the cloth winding roll, there is provided a cloth pressure bonding device such as a pad or a pressure roller for pressing the cleaning cloth at the time of cleaning against the outer surface of the cylinder.

In the cylinder cleaning device constructed as described above, the cloth take-up roll shaft is continuously or intermittently driven to rotate at a predetermined speed by a driving device, and at the same time, a cloth pressing device such as a pressure pad is operated to clean the cleaning cloth. It is pressed against the outer surface of the cylinder and wipes off the deposits. The motor used to drive the core of the conventional cloth take-up roll is a positive rotation constant speed motor with a speed reducer, or the linear actuator such as an air cylinder is used to reciprocate the lever,
The ratchet mechanism is used to drive the core instead of rotating it. For rewinding the cloth after the cleaning, for example, Japanese Patent Publication No. 56-
As disclosed in 32069, the fabric supply roll was manually rotated to reverse and rewind.

A cylinder cleaning device provided with a mechanism for automatically rewinding the cloth has been proposed. This type of cylinder cleaning device is equipped with a drive device such as a motor for reversing the cloth supply roll. When the cleaning is completed, the drive device is operated to rewind the cleaning cloth. A cylinder cleaning device having such an automatic cloth rewinding mechanism is disclosed, for example, in Japanese Patent Publication No. 4-64.
No. 509 and JP-A-1-122437.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of the essential parts of the first embodiment of the present invention. FIG. 2 shows the first system configuration of the present invention. The cleaning unit 1 is rotatably supported by a support shaft 2 with respect to the main body frame 3. The cleaning unit 1 is configured so that it can be pressed against or separated from the outer surface of a cylinder 4 such as a blanket cylinder by rotating about a support shaft 2 by using a driving means such as an air actuator (not shown). There is. An appropriate number of stays 7 are fixed between the side plates 5 and 6 forming the cleaning unit 1, and a cloth supply roll 9 for supplying a cleaning cloth 8 and the cleaning cloth 8 are provided.
A cloth take-up roll 10 for taking up the cloth is installed, and a cloth pressure bonding device 11 for pressing the cleaning cloth 8 delivered from the cloth supply roll 9 against the outer surface of the cylinder 4 is provided in the middle thereof. Further, the cloth supply roll 9 side is equipped with a cloth rewinding device 20 for rewinding the used cleaning cloth to the cloth supply roll 9 after the cleaning operation and a cloth rewinding amount adjusting device 30 for adjusting the rewinding amount of the used cleaning cloth. The cloth take-up roll 10 side is provided with a drive device 40 for continuously or intermittently winding the cleaning cloth 8 during the cleaning operation, that is, for drawing the cleaning cloth from the cloth supply roll 9.

Here, the cloth pressure bonding apparatus 11 of this embodiment is a pressure pad made of a solid member made of an elastic material such as rubber or synthetic resin, and a pressure member made of an expansion member for supplying air to expand the inside. It is configured to include a cloth pressing member such as a pad and a pressure contact roller, and to operate them to press the cleaning cloth against the outer peripheral surface of the cylinder to separate it. The cloth rewinding device 20 includes a winding spring 21 that generates a return torque for rewinding a used cleaning cloth of an arbitrary length, a winding spring accumulation wheel 22 that accumulates the winding spring 21, and a winding spring winding wheel that winds the winding spring 21. Equipped with 23. The coil spring accumulation wheel 22 is arranged on one side frame 5 of the cleaning unit, and the coil spring winding wheel 23 is arranged on the shaft of the cloth supply roll 9. The coil spring 21 is wound around a coil spring accumulation wheel 22 as shown in FIG. 3, and the tip of the coil spring 21 is locked by a coil spring winding wheel 23.

The operation of the cloth rewinding device 20 will be described. In the cloth supplying operation at the time of cleaning, as shown in FIG. 3A, as the cloth supplying roll 9 rotates, the winding spring accumulating wheel 22 moves in the direction of arrow a. The pulled-out winding spring 21 is wound around the winding spring winding wheel 23 to store energy required for the reverse rotation of the cloth supply roll 23. In the cloth rewinding operation after cleaning, when the clutch 46 is operated to disconnect the drive device of the cloth take-up roll to set the cloth take-up roll in the free state, the winding spring 21 returns in the direction of arrow b shown in FIG. 3-2. The return torque of the coil spring acts on the cloth supply roll 9, reverses the cloth supply roll 9, and rewinds the cleaning cloth that has been pulled out and used. At this time, by operating the cloth rewinding amount adjusting device 30, the rewinding length, that is, the rewinding amount can be adjusted.

The winding spring winding wheel 23 is arranged on the shaft of the cloth supply roll 9, and the restoring force of the winding spring to the winding spring accumulation wheel 22 is directly applied to the shaft of the cloth supply roll. It is not limited to this. In short, the winding spring 21 is wound up with the rotation of the cloth supply roll,
Any structure may be used as long as this accumulated energy acts on the reverse rotation of the cloth supply roll. For example, the winding spring winding wheel 23 is arranged on the side frame 5, and a mechanism for mechanically connecting the shaft of this wheel and the shaft of the cloth supply roll 9 is provided to indirectly drive the shaft of the cloth supply roll with a reverse driving force. It is also possible to adopt a structure that causes

The cloth rewinding amount adjusting device 30 is disposed on the other side frame 6 of the cleaning unit, and is a ratchet wheel 31 mounted on the shaft of the cloth supply roll 9.
The side frame 6 includes a ratchet pawl 32 that is rotatably supported by the ratchet wheel 31 and is locked to the ratchet wheel 31. An actuator 33 that locks the ratchet pawl 32 on the ratchet wheel 31 and unlocks the ratchet wheel 31. There is. As shown in FIG. 4, the ratchet pawl 32 is normally biased by a spring 34 in a direction to engage with the ratchet wheel 31, and is rotated by the operation of the actuator 33 against the biasing force of the spring 34. The lock is released. Reference numeral 35 is a spring receiver fixed to the side frame 6. Here, the ratchet wheel 31, the ratchet pawl 32, and the spring 34 constitute a mechanism for stopping the rewinding of the cloth to the cloth supply roll. Further, the actuator 33 constitutes an operating means for operating the cloth rewinding stop mechanism to start / stop the cloth rewinding.

The operation of this cloth rewinding amount adjusting device 30 is shown in FIG.
Will be described with reference to. When the cleaning operation is not performed, the ratchet pawl 32 is locked to the ratchet wheel 31 by the spring 34, as shown in FIG. 4 (1). When the cleaning operation is started and the cleaning cloth 8 is pulled out from the cloth supply roll 9 in the direction of arrow c, the ratchet wheel 31 is also driven by the rotation of the shaft of the cloth supply roll 31 as shown by arrow d in FIG. 4B. Rotate in the direction. At this time,
The ratchet pawl 32 operates so as to ride over the teeth of the ratchet wheel, and thus is not locked. During this time, the winding spring 21 is wound around the winding spring winding wheel 23.

When the cleaning operation is completed, the actuator 3
3, the shaft 33a pushes the end of the ratchet pawl 32 in the direction of arrow e. Then, the engagement between the ratchet pawl 32 and the ratchet wheel 31 is released, and the ratchet wheel 31 rotates in the direction of arrow f together with the cloth supply roll 9 by the winding spring 21. That is, when the coil spring 21 wound by the coil spring winding wheel returns to the coil spring accumulation wheel 22, the cloth supply roll 9 is reversed to rewind the used cleaning cloth in the arrow g direction.

In this embodiment, the cloth rewinding amount adjusting device is arranged on the cloth supply roll side, but it may be arranged on the cloth winding roll side. The cloth rewinding amount adjusting device may be a mechanism that stops the rotation of the shaft of either the cloth supply roll or the cloth take-up roll when the rewinding of the cleaning cloth reaches an arbitrary length. For example, a configuration may be adopted in which a brake device is provided on the shaft of any one of the rolls and the brake device is activated after a predetermined time has elapsed from the start of rewinding the cleaning cloth.
In this case, since the brake device starts / stops the cloth rewinding, it has a function of the cloth rewinding operation means.

Next, the cloth feed control including the cloth rewinding amount adjustment will be described. FIG. 5 shows the system configuration of the cloth feed control device. This system is provided with a cloth length detection sensor 51 for detecting the running amount of the cleaning cloth and a cloth contamination degree detection sensor 52 for detecting the degree of dirt of the cleaning cloth in order to control the supply amount or the rewinding amount of the cleaning cloth 8. ing. At the time of cleaning, the control board 50 issues a drive signal for winding the cloth to the drive device 40 of the cloth winding roll to drive the cloth winding roll to rotate continuously or intermittently to pull out the cleaning cloth from the cloth supply roll.
The cloth supply amount at this time is controlled by the measured value and the set value obtained based on the signal from the cloth length detection sensor 51.

At the end of cleaning, a stop signal is sent to the drive unit 40, and at the same time, the actuator 33 is operated to release the locking between the ratchet pawl 32 and the ratchet wheel 31. Then, the restoring force of the coil spring acts on the shaft of the cloth supply roll, and the cloth supply roll is reversed. When the rewinding of the used cleaning cloth is started, the control panel 50 causes the cloth length detecting sensor 51 to
And a detection signal from the cloth dirtiness detection sensor 52, and a cleaning cloth that can be used for the next cleaning, that is, a cleaning cloth having a small dirtiness due to the signal processing of the cloth dirtiness detection sensor is rewound for a predetermined length, the actuator. 33 is operated, the ratchet claw is locked to the ratchet wheel, and the rotation of the cloth supply roll is stopped.

As the cloth length detecting sensor 51, a yarl meter for detecting the length of the cleaning cloth or an optical sensor for optically reading the marker by attaching markers at fixed intervals to the cleaning cloth is used. Particularly, in the case of an optical sensor, the control board 50 counts the signal from the sensor 51 and calculates the cloth rewinding amount based on this count value. Here, the control for rewinding the wash cloth of a usable length by detecting the dirt degree of the wash cloth is described, but the cloth rewind amount is set in advance without using the cloth dirt degree detection sensor 52, Of course, it is also possible to control so that the cloth rewinding is performed by the signal processing of only the cloth length detecting sensor.

Next, a second embodiment of the present invention will be described. In this embodiment, a pressure roller is used as the cloth pressing member in the cloth pressure bonding apparatus, and the pressure roller and the cloth winding roll are driven. In particular, the rewinding amount adjustment of the used cleaning cloth after the completion of washing is characterized by performing the reverse drive control of the pressure contact roller without using the cloth rewinding amount adjusting device 30 of the first embodiment. FIG. 6 shows a main configuration of a cylinder cleaning device according to a second embodiment of the present invention. Figure 7 shows the cleaning unit A
The structure of a -A cross section is shown. The same members as those of the cleaning unit shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The drive unit 40 uses a motor 41 as a drive source, and a pulley 42 is attached to the motor shaft. The pulley 12 is attached to the shaft of the pressure roller 110,
A pulley 13 is attached to the shaft of the cloth winding roll 10 via a slip mechanism. These pulleys 1
A transmission belt 43 is stretched between the pulleys 2, 13 and the pulley 42 of the motor. The pressure roller 110 and the cloth winding roll 10 are reversibly rotated by the drive device 40.

As shown in FIG. 8, a motor mounting base 3b is fixed to a hole 3a formed in the side frame 3, and a motor 41 is mounted on the motor mounting base 3b. The rotation of the motor 41 is transmitted to the pulley 42 after being decelerated via the gear transmission as required. Note that 44
Is a belt tension pulley, which is supported by a lever 45 rotatably attached to the side frame 3 and pushes the belt tension pulley 44 in the belt direction by a biasing means such as a spring (not shown) to tension the belt 43. It is properly maintained. Further, between the machine frame 3 and the side frame 5 of the cleaning unit 1, a cloth rewinding device 20 having the same configuration as that of the above embodiment is installed.

The control panel controls the drive unit 40 to control the feeding of the cleaning cloth 8. The control panel controls the rotation speed and rotation direction of the pressure roller and the rotation of the motor for intermittently or continuously performing its operation. Control number, reversible, drive stop, etc. The reverse rotation operation of the pressure contact roller is programmed in advance according to the system specifications, and is set so that an arbitrary length usable in the next cleaning operation is rewound. This rewinding amount can be set arbitrarily. The pressure roller 1
A spray bar 18 for supplying a cleaning liquid to the cleaning cloth 8 is disposed on the upstream side of 1.

According to the above construction, during cleaning, the pressing roller 110 is continuously or intermittently rotated to pull out the cleaning cloth 8 from the cloth supply roll 9 and clean the outer surface of the cylinder 4. At this time, the peripheral speed of the press roller 110 is constant, but the peripheral speed of the cloth winding roll changes depending on the cloth winding amount. The difference in peripheral speed is compensated by a slip mechanism provided on the cloth winding roller side. That is, when the cloth winding amount is small and the diameter of the cloth winding roll is small, the peripheral speed of the cloth winding roller is higher than that of the pressure contact roller, but due to the friction between the pressure contact roller and the cleaning cloth, Power transmission to the shaft of the roll is suppressed by the slip mechanism. That is, a slip occurs between the pulley 13 and the shaft, and the cloth take-up roll rotates following the pull-out of the pressure roller.

A cleaning liquid is sprayed from the spray bar 18 onto the cleaning cloth 8. In this state, the cylinder 4 is rotated, and the adhering matter attached to the outer surface thereof is wiped off with the cleaning cloth 8. In this case, the pressing force of the pressure contact roller 11 can be adjusted by drive control of an air actuator or the like. On the other hand, when the pressure contact roller is driven in reverse after the cleaning is completed, the used cleaning cloth rewound by the pressure contact roller is rewound onto the cloth supply roll. At this time, the reverse rotation of the cloth take-up roll is performed in the same manner by the above-mentioned slip mechanism. When the cleaning cloth of a predetermined length is rewound, the pressing roller is stopped. After that, it is in a standby state for the next cleaning operation.

Next, a third embodiment of the present invention will be described. The present embodiment is characterized in that a cloth winding roll is movably supported on a side frame, the cloth winding roll is brought into contact with a pressure contact roller by an urging means, and is driven to rotate as the pressure contact roller rotates. Is. FIG. 9 shows the third aspect of the present invention.
2 shows a configuration of a main part of the cylinder cleaning device of the embodiment. FIG.
Shows the configuration of the D-D cross section of the cleaning unit. FIG. 11 shows a support structure for the cloth take-up roll. FIG. 12 shows the configuration of the cleaning unit viewed from the side. The same members as those of the cleaning unit shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The cloth winding roll 10 is rotatably supported by a slide block 15 slidably mounted on rectangular windows 14 formed on the side plates 5 and 6. Further, the slide block 15 is biased toward the pressure contact roller 11 side by a biasing means such as a spring 16.
Therefore, the cloth take-up roll 10 is always in contact with the press roller 11
In order to wind up the used cleaning cloth 8 or to re-use a part of the used cleaning cloth that has been wound up by being rotated by the rotation of the pressure contact roller 11, And unwind it. During the cleaning operation, the cleaning progresses and the winding amount increases, so that the cloth winding roll 10
As the outer diameter increases, the slide block 15 resists the urging force of the spring 16 and moves to the right in the figure to maintain the contact state. On the other hand, after the washing is completed, the used cleaning cloth is unwound from the cloth take-up roll by the reverse rotation of the pressure contact roller, and the diameter of the roll decreases, and the slide block is pushed by the spring to the left in the figure. Moving.

When using the cylinder cleaning apparatus of the above embodiment, the cleaning cloth 8 is transferred from the cloth supply roll 9 to the pressure roller 1.
1 is set on the cloth take-up roll 10 and the cleaning unit 1 is rotated about the support shaft 2 by a driving means such as an air actuator (not shown) so that the surface of the cleaning cloth 8 in the pressure contact roller 11 portion is moved to the cylinder 4 Abut the outer surface of the. Then, in the cleaning operation, when the cleaning cloth 8 is fed by a predetermined amount, the pressing roller 11 is driven and rotated by a predetermined angle to advance the cleaning cloth 8 by a predetermined amount and send a new cleaning surface to the cleaning unit. . In this case, the pressure roller 11 may be kept in pressure contact with the cylinder 4 or may be in a separated state. As described above, since the cloth take-up roll 10 is in contact with the pressure contact roller 11 by the urging force of the spring 16, the fed cleaning cloth 8 is automatically taken up by the cloth take-up roll 10 by its frictional force. As the cleaning operation progresses and the winding amount of the cleaning cloth 8 increases and the outer diameter of the winding roll 10 increases, as described above, the slide block 15 resists the urging force of the spring 16 and, as shown in FIG. By moving to the right as shown, the increase in the winding amount is absorbed while maintaining the contact state.

At the time of the cleaning, the coil spring 21 is wound around the coil spring winding wheel 23 by pulling out the cleaning cloth 33 from the cloth supply roll 9, and energy for rewinding the cloth is accumulated. As a result, the cleaning cloth 33 is pulled by the spring force of the winding spring 21 between the cloth supply roll 9 and the cloth winding roll 10 via the pressure contact roller 11. After the cleaning is completed, the pressure roller 11 is rotated in the reverse direction so that the cloth winding roll 10
When is rotated in the opposite direction to the winding direction, the used cleaning cloth wound up is rewound to the cloth supply roller 9 side. The cleaning cloth sent back by this operation is rewound on the cloth supply roll by the reverse rotation of the cloth supply roll itself due to the returning operation of the winding spring 21. The feeding operation of the cleaning cloth 8 in the cleaning device is
Since the rotation is performed by controlling the rotation of the pressure roller 11 whose outer diameter is always constant, it is possible to easily obtain a precise and accurate feeding operation without using a complicated fixed-size feeding mechanism. Further, the winding or unwinding operation of the cloth winding roll 10 is performed by bringing the cloth winding roll 10 into contact with the pressure contact roller 11 by the biasing means such as the spring 16 and utilizing the rotational force of the pressure contact roller 11. , The configuration is extremely simple.

In the above description of the embodiment, an example in which the cloth winding roll 10 is brought into contact with the pressure contact roller 11 is shown. However, a cleaning cloth is pressed against the outer surface of the cylinder between the cloth supply roll and the cloth winding roll. If a pressure contact roller is provided and the cleaning roller is driven to feed the cleaning cloth, it is possible to obtain the effect of eliminating the need for a complicated control mechanism for constant size feeding as in the prior art. Needless to say. Also,
In the description of the above embodiment, the cleaning unit 1 is attached to the support shaft 2
The case where the present invention is applied to a so-called swing type in which the pressure contact roller 11 is pressed against the outer surface of the cylinder 4 or separated from the outer surface of the cylinder 4 by rotating the cleaning unit 1 is moved back and forth. The present invention can also be applied to a reciprocating type in which pressure contact and separation are performed by. Further, the rotation direction of the cylinder 4 during the cleaning operation may be either, and when the moving directions of the pressure contact surface of the pressure contact roller 11 and the cylinder 4 are set to coincide with each other, the pressure contact surface based on the difference between the peripheral speeds of the both. The relative movement of the two will result in a cleaning action. Further, although the power transmission system of the pressure contact roller is constituted by a pulley and a belt, a gear mechanism can be used.

[0031]

As described above, according to the present invention, the reverse driving force of the cloth supply roll necessary for rewinding the used cleaning cloth is applied to the winding spring by utilizing the rotation of the cloth supply roll during cleaning. Since the configuration is such that the fabric is rewound, the fabric rewinding mechanism is simplified and the device can be downsized.
