Definitions

the invention relates to a device for cleaning cylinders in printing presses with a cleaning device which can be turned on and off the cylinder.
a device of this type is known from DE 36 14 542 A1.
This cleaning device is used to clean a plurality of cylinders within a rotary printing press, in that it can be moved in succession to a plurality of cylinders in different printing presses by means of a transport device.
the transport device can be moved along the printing press by means of conveying means in a guide system.
the conveying means are in engagement with a drive unit. It is disadvantageous here that the necessary means are very complex and the time required for moving the cleaning device from one printing unit to the next printing unit is high.
Another printing press cylinder washing device is known from EP 0 591 634 A1.
This device can be extended and retracted axially parallel to a cylinder in an opening in a machine frame.
the washing device itself is accommodated in a suspension device having linear guides.
the suspension device has end connections for coupling or decoupling supply lines in such a way that a connection is automatically generated when the washing device is inserted.
the suspension device with washing device is pivoted onto or off the cylinder to be cleaned by means of a compressed air cylinder and coupling gear.
the compressed air cylinders and the suspension device are arranged in the opening and thus considerably restrict the space for service work.
the linear guides and the coupling gear represent a complex solution.
the object of the invention is to provide a device for cleaning cylinders, which can be installed and removed in a printing press with little effort, without constantly restricting the space for service work.
the positioned cleaning device can be pushed in laterally on an industrial conveyor to a cylinder to be cleaned through the opening of a printing press and can be moved out on the industrial conveyor.
the flow conveyor can be moved so that only one floor conveyor is required for all cleaning devices within a printing press.
Transverse guides are preferably arranged in an opening on the machine frame (running parallel to the axis of the cylinder), into which the industrial truck with cleaning device can be pushed into and out of an "insertion position". From the "insertion position", the cleaning device leaving the industrial truck is moved longitudinally by means of a first actuating device via longitudinal guides into a "standby position" to the cylinder to be cleaned, i.e. in the direction of sheet travel or against the sheet travel direction. By means of a second actuating device, the cleaning device is then put into the “working position” or put back into the “ready position”.
the solution according to the invention is particularly suitable for cleaning cylinders, for example impression cylinders in printing machines. These impression cylinders are difficult to access due to their geometrical arrangement within the printing press. If the solution according to the invention is used in a sheet-fed printing press of a higher format class, the cleaning device has a relatively high mass. Such a device can be installed or removed manually only with great effort.
washing rollers for example washing brushes with a squeegee or a washing machine with a pressure element
Washing rollers or the washing cloth spindles are mounted in the side walls arranged on the end face and are surrounded by a housing, which is preferably open on one side.
nozzles for detergent and / or water in the housing are assigned to the washing rollers or the wash cloth.
a roller drive for. B. an electric motor, arranged on the housing so that a complete cleaning unit is available as an assembly (including the connections for water, detergent and energy).
a printing unit of a sheet-fed offset printing press essentially consists of a printing cylinder 1 which acts as an impression cylinder and which is operatively connected in a known manner to an adjacent blanket cylinder 3 and a plate cylinder 4 assigned to the blanket cylinder 3.
a transfer drum 5 is arranged upstream of the printing cylinder 1 in the direction of sheet travel and a further transfer drum 6 is arranged downstream.
a cleaning device 2 is to be arranged, which can be placed on and off the printing cylinder 1.
the printing unit each has a laterally arranged machine frame 7, in which there is an opening.
This opening serves in a known manner as a "man hole” for service work.
Cross guides 9 running parallel to the cylinder 1 are arranged on the machine frame 7 within the opening.
a floor conveyor 8 essentially formed from a base frame with brackets accommodates the cleaning device 2.
the industrial conveyor 8 has a plurality of steering rollers 18 which are used for moving between the printing units.
9 centering rollers 17 are rotatably arranged on the industrial conveyor 8 parallel to the transverse guides.
the industrial conveyor 8 can also be movable on an air cushion or by means of guide devices arranged, for example, in the floor area.
An actuating device 12 is arranged on the side of each machine frame 7 below the cylinder 1. It consists essentially of a working cylinder 13 with a piston rod, which is received in a pivot joint 14. A lever 15 is also accommodated in the swivel joint 14 and has a cam roller 16 which is in contact with a longitudinal guide 11 fixed to the frame. Each lever 15 has centerings 20, to which centering means 21 arranged on the cleaning device 2 are assigned in the correct position.
the cleaning device 2 furthermore has connections for detergent, water and energy, which are automatically coupled with corresponding counterparts at the latest in the “ready position” assigned to the cylinder 1 to be cleaned. The cleaning device is thus connected to all the supply lines required.
the mode of operation is as follows: the cleaning device 2 is positioned on the industrial conveyor 8.
the industrial conveyor 8 provided with steering rollers 18 is moved from one side into an opening in the machine frame 7 of the printing press into a "insertion position 10".
the centering rollers 17 which are arranged on the industrial conveyor 8 and which engage with the transverse guides 9 fixed to the frame serve for this purpose.
the transverse guides 9 are preferably provided on the open side with a bevel so that the industrial conveyor 8 can be accommodated in the transverse guides 9 with little effort on the end face.
the housing of the cleaning device 2 is brought closer to the levers 15 of the first actuating device 12.
the levers 15 have centerings which form-fit with the centering means 21 on the housing of the cleaning device 2. If a coupling has taken place between the centerings 20 and the centering means 21, the insertion position 10 has been reached.
the first actuating device 12 now moves the cleaning device 2 along the longitudinal guides 11 by means of the lever 15 and the working cylinder 13.
Each cam roller 16 runs on the longitudinal guide 11.
the law of motion of the longitudinal guide 11 and lever 15 with cam roller 16 is designed such that the cleaning device 2 from the insertion position 10 (and thus also) out of the industrial conveyor 8 during the longitudinal displacement is lifted out. This clears the floor conveyor 8.
the industrial conveyor 8 can, for example, be removed from the printing press, accommodate a further cleaning device 2 and thus feed a further printing unit.
the actuating device 12 is activated until the cleaning device 2 has reached a standby position 19. That is, the working cylinders 13 move to a predetermined position (standby position 19) and move the levers 15 with the cleaning device 2 via the longitudinal guides 11.
the cleaning device 2 is held in the standby position 19 by the actuating device 12. In this position 19, the cleaning device 2 is automatically connected to the connections for water, detergent and energy. If the cleaning device 2 is to clean the printing cylinder, the second actuating device 23 is activated. The working cylinder 22 lifts the cleaning device 2 via the cross member 24 around the swivel joint 14 until the cleaning device 2 rests on the pressure cylinder 1. So that the job is done, the pressure cylinder 1 can be washed in a known manner. If the cleaning device 2 is to be switched off, the rod of the working cylinder 22 is retracted and the cleaning device 2 is thus lowered into the standby position 19.
the cleaning device 2 If the cleaning device 2 is to be replaced, for example for service purposes, it is moved back from the standby position 19 into the insertion position 10 via the longitudinal guides 11 and placed on a provided floor conveyor 8.
the industrial truck 8 can then be laterally moved out of the opening in the machine frame 7 again.
the same cleaning device can also be moved to another printing unit by means of industrial conveyors 8.
the first actuating device 12 shown can alternatively also be formed by a drive motor which moves the cleaning device 2 from the insertion position 10 into the ready position 19 by means of longitudinal guides 11 by means of a cable pull.
