Definitions
- the invention relates to a device and a method for cleaning a cylinder or a roller of a printing press with a cleaning agent web, a first supply roll for unwinding the cleaning agent web and a second supply roll for winding up the cleaning agent web being provided for the cleaning agent web, a winding device for feeding the section by section Detergent web is rotatably drivable with a drive device, a measuring device is provided which detects the radius of at least one supply roll and an adjusting device is provided, with which the amount of a respective rotary movement of the winding device can be changed as a function of the detected radius of the supply roll.
- Such cleaning devices are used on printing presses in order to remove excess operating materials, for example excess printing ink, from a cylinder or a roller.
- the terms cylinder and roller should therefore be used as synonyms below.
- Such a cleaning device with two spindles is known from DE 43 06 676 AI, with the supply roll with the clean detergent web being stored on one spindle and the waste roll with the used detergent web on the other spindle.
- Electric motors are provided for driving the spindles, so that the cleaning agent web can be conveyed in sections according to a control program and finally rewound after the supply roll has been completely used up.
- a cleaning device is also known from US Pat. No. 5,275,104, in which the waste roll is driven step by step and in continuous operation by an electric motor, while the cleaning track is pressed pneumatically against a cylinder to be cleaned by a roller.
- a disadvantage of these known devices is that the feed of the cleaning agent web changes depending on the radius of the waste roll. As a result, in the case of a waste roll with a large radius, with each section-wise advance of the cleaning agent web, more cleaning agent web is conveyed on than is necessary for cleaning the roller or the cylinder. This unnecessary consumption of detergent web leads to relatively high operating costs.
- the invention has for its object to provide a device and a method for cleaning a cylinder or a roller of a printing press, the consumption of cleaning agent web as low as possible is held.
- the object is achieved according to the invention by a device of the type mentioned at the outset, in which the cleaning agent web can be pressed against the circumference of the cylinder or the roller by means of a pressing device, the pressing device also being adjustable between an employed working position and a parked rest position by means of the drive device.
- a method is carried out in which the detergent web is unwound from a first supply roll and wound on a second supply roll in cycles, the detergent web being transported by an approximately constant length per work cycle, the detergent web per work cycle in each case between one on the cylinder or the roller employed working position and a parked rest position, and the respective further transport takes place only in the turning movement or only in the parking movement in only one direction of rotation.
- the teaching according to the invention is based on the basic idea that the radius of a roll, in particular a waste roll, is recorded, so that the winding device for winding up the waste roll is then only rotated to such an extent that the required length of the cleaning agent web is wound onto the circumference of the waste roll. In each cleaning operation, only this run length is used and replaced by a fresh length for the next operation. As a result, this means that the rotational movement of the winding device can be changed with each section-wise feed of the cleaning agent web depending on the radius of the waste roll. If the radius of the waste roll is small, the winding device must have a relatively large one Angle of rotation are conveyed further to ensure the necessary feed of the cleaning agent web. With a large radius of the waste roll, on the other hand, only a relatively small rotary movement of the winding device is required to ensure the corresponding advance of the detergent web.
- the amount of the rotary movement of the winding device is changed during the section feed of the cleaning agent web in such a way that the length of the feed section remains approximately constant regardless of the radius of the waste roll. This measure ensures that in each case a feed section with a constant length is conveyed further, the length of the feed section being selected so that a sufficient cleaning effect is achieved.
- the cleaning agent web is pressed against the circumference of the cylinder or the roller by means of a pressure-type doctor device. This measure greatly increases the cleaning effect that can be achieved with the cleaning agent web and reduces consumption.
- the pressing device should be adjustable between an employed work position and a parked rest position. This measure ensures that the cylinder or the roller is not permanently cleaned, but is only cleaned when the pressing device is adjusted to the working position employed.
- the drive device is used for adjustment the pressing device
- the winding device of the waste roll can be driven indirectly or directly rotatably.
- both the winding device of the waste roll and the pressing device are driven with only one drive device, for example a pneumatic or hydraulic actuating cylinder.
- a freewheel device can be provided between the drive device for simultaneously driving the winding device and the pressing device and the winding device of the waste roll.
- the actuating movement of the drive device is transmitted to the winding device only in one direction. In the other direction, the freewheel runs freely, so that the winding device is driven in only one direction.
- Particularly simple cleaning devices can be implemented using mechanical lever mechanisms. To ensure the function, it is necessary that the effective lever length of the lever mechanism can be changed depending on the radius of the waste roll. In other words, this means that the required change in the drive rotation angle is ensured by changing the effective lever length of the lever mechanism.
- the adjustment of the effective lever length of the lever mechanism can be carried out, for example, by an adjusting lever, at one end of which a roller is rotatably mounted, and the roller comes to rest on the circumference of the waste roller. By changing the radius of the waste roll, this position lever is then changed in its position, whereby by the Changing the position of the control lever affects the effective lever length of the lever mechanism.
- FIG. 2 the cleaning device according to FIG. 1 in a second process state
- the device 01 shown in FIG. 1, e.g. B. a cleaning device 01 is used to clean a fixed in an inking roller 02.
- a cleaning agent web 03 for example a web of cleaning paper or a cleaning cloth
- a winding device 06 for example a drive spindle 06
- the supply roll 04 has just been changed and the waste roll 07 thus has its minimum radius, which essentially corresponds to the radius of the winding device 06.
- a pressure device 08 which is designed in the manner of a pressure doctor blade 08.
- the pressing device 08 is firmly connected to an adjusting lever 09, which can be pivoted about an axis of rotation 12 by means of a drive device 11, which is designed in the manner of a pneumatic drive cylinder 11.
- the pressing device 08 can be set against the inking roller 02 by pivoting the adjusting lever 09.
- the drive device 11 acts on the winding device 06 via the setting levers 13, 14 and 16, which together form a lever mechanism.
- one end of the setting lever 16 includes the winding device 06 with a freewheel device 15.
- a spring element 18, in particular a tension spring 18, is provided between the control lever 09 and the connecting axis between the control levers 13 and 14 in order to be able to ensure that the lever mechanism from the control levers 13, 14 and 16 can rest at any time without play.
- the diameter of the waste roller 07 is detected with a roller 19 which is rotatably mounted at the end of an actuating lever 21.
- the other end of the control lever 21 is connected to the connecting axis between the control levers 13 and 14.
- the adjusting lever 21 moves downward or upward, thereby changing the effective lever length of the lever mechanism formed from the adjusting levers 13, 14 and 16.
- the device 01 is shown in the subsequent process step after the actuating rod 17 has been extended.
- the cleaning agent web 03 was wound a little way onto the waste roll 07 and thus conveyed further.
- the pressing device 08 was turned against the inking roller 02 by pivoting the setting lever 09 clockwise.
- the position of the actuating lever 16 in the process state according to FIG. 2 is indicated by dashed lines in FIG. 1. It can be seen that, due to the relatively large effective lever length of the lever mechanism, the adjusting lever 16 is pivoted through a relatively large angle when the adjusting rod 17 is extended. The feed length when conveying the cleaning agent web 03, which results from the radius of the waste roller 07 and the pivoting angle of the actuating lever 16, is thereby maintained to a sufficiently high degree despite the relatively small radius of the waste roller 07.
- FIG. 3 shows the device 01 in a process state in which the supply roll 04 is almost complete is exhausted and the waste roll 07 has a correspondingly large radius.
- the actuating rod 17 is retracted and thus the pressing device 08 is switched off by the inking roller 02.
