Description

The invention relates to a work for a sheet processing machine, which is formed for example by a printing unit and which comprises a main drive arrangement for driving a plurality of rotatable rollers and / or cylinders according to the preamble of claim 1.

A sheet processing machine usually has a main drive for driving at least the sheet transport serving cylinders or rollers using a gear train on. In addition, individual drives are used for directly driving individual cylinders, so that these cylinders can be driven independently of the main drive. Thus, it is known to drive the cylinders of a printing unit, an inking unit and a dampening unit with one or more independent of the main drive individual drives.

A printing unit is a part of the sheet processing machine in which the printing of a printing material or a substrate between a forme cylinder and a transfer cylinder takes place. Printing ink is applied in an inking unit via a clocked ink lifter by a Farbduktor first on a first Verreibwalze, the so-called distributor roller and from this further on a plurality of successively arranged transfer rollers, the so-called complaint rollers passed. These transfer the ink to a lower inking roller. A dampening unit moistens the part of the forme cylinder that is not coated with ink to produce a uniform print result without blurring.

The ink lifter, called a lifter for short, is a roller in the inking unit of the printing unit, which forwards the ink from a ink ductor to a first inking roller, in short called the ink driver. The inkwheel alternately contacts the ink fountain roller and the ink fountain roller, which is realized by a cam mechanism with a driven lift cam. The rotary drive of the color lifter takes place via friction, the alternating contact with the ink fountain roller and the ink fountain roller.

The DE 40 12 292A1 shows a lift drive, as it is used in the inking unit of an offset printing press. On a rotating drive curve a Maltese cross is coaxially mounted frontally, which is only once indexed during a full revolution of a drive shaft.

The DE 42 31 260 C2 discloses a central rotary drive for simultaneously driving a plurality of ink-transporting rollers, in particular a plurality of inking rollers. The inking rollers stand with their each recorded on a pin gear with a driven side of a drive wheel central drive in drive connection. The color lifter is frictionally rotated by alternating contact with a color ductor and one of the inking rollers. The disadvantage is that transmit different peripheral speeds of the ink fountain roller and the ink roller during the printing on the color lifter. In this case, the inking roller has a higher peripheral speed than the ink fountain roller, which during the printing leads to the fact that the ink lifter is decelerated at the ductor and accelerated at the inking roller. The acceleration of the color lifter takes place in a very short time. This results in a short high drive power of the main drive. This causes a moment peak with a detrimental effect on print quality. The occurrence of the torque peak by accelerating contacting the ink lifter with the ink fountain roller is also referred to as a lifter.

The invention has for its object to provide a work for a sheet processing machine. The object is achieved by the features of claim 1.

The plant is intended for a sheet-fed machine so that it forms part of the sheet-processing machine. The work is preferably formed by a printing unit of the sheet processing machine. The sheet processing machine is preferably a printing press, in particular for offset printing. The factory includes several rotatable rollers and / or rotatable cylinders. At least several of the rotatable rollers and / or cylinders are drivable. At least several of the rotatable rollers and / or cylinders contact each other in pairs. The drive of several of the rotatable rollers and / or cylinders can be realized via a main drive arrangement. The main drive arrangement preferably comprises a main drive, which is formed by at least one motor. The at least one engine of the main drive assembly preferably comprises an electric motor, a pneumatic motor and / or a hydraulic motor. The main drive assembly preferably further includes torque transmitting connections for transmitting torque from the main drive to the rotatable rollers and / or cylinders.

The factory includes at least one further drive in addition to the main drive arrangement. The further drive or other drives are by a Farbreiberwalzenantrieb for driving a first rotatable inking roller of the factory and / or by a Farbheberkurvenscheibenantrieb to drive a Farbheberkurvenscheibe and / or by an eccentric bearing drive for driving a cam plate of an eccentric bearing one of the first ink roller directly downstream roller formed. The plant can thus comprise one, two or three of said further drives. The further drive or the further drives are independent of the main drive arrangement.

The ink fountain roller drive is used for direct drive of the first rotatable ink roller and is independent of the main drive assembly. The first inking roller, which may also be referred to as a first ink driver for short, is formed by a rotatable roller and forms a component of the work. The factory may include additional inking rollers in addition to the first inking roller, but it may also be the sole inking roller of the factory.

A particular advantage of the ink fountain roller drive is that the first ink roller can be operated with an adapted peripheral speed, so that the lifter stroke is minimized.

The further drive or the further drives preferably each comprise at least one motor and optionally gear elements. The at least one motor of the further drive preferably comprises an electric motor, a pneumatic motor and / or a hydraulic motor. The further drive or the further drives particularly preferably each comprise exactly one motor.

A first preferred embodiment of the plant comprises exactly one of said further drives, which is designed in addition to the drive of the first rotatable inking roller, for driving the Farbheberkurvenscheibe and / or for driving the roller cam of the eccentric bearing. Thus, the exactly one further drive is preferably designed for at least two of the mentioned drive functions. It is particularly preferred that exactly one further drive be the ink roller drive, which is additionally designed to drive at least the roller cam of the eccentric bearing.

A second preferred embodiment of the plant comprises exactly two of said further drives, wherein one of the two further drives is complementary to the drive of the first rotatable inking roller, for driving the Farbheberkurvenscheibe and / or for driving the roller cam of the eccentric bearing is formed. The two drives are preferably formed by the ink fountain roller drive and the eccentric bearing drive.

A third preferred embodiment of the plant comprises exactly three of said further drives.

In the described embodiments with several of the other drives, the plant preferably further comprises an electronic control for controlling the at least two further drives. The electronic control ensures that the first inking roller, the ink lifting cam and the roller cam rotate at an adjusted speed and phase according to the functional sequence in the factory. If the plant includes only one of the further drives, the adjusted rotational speed and phase are ensured by torque transmitting connections between the further drive and the first inking roller, the Farbheberkurvenscheibe and the Walzenkurvenscheibe.

The further drive or the further drives are preferably designed in each case as a single drive. The drivable by the ink fountain roller drive first inking roller is thus exclusively driven by the Farbreiberwalzenantrieb or drivable by the Farbheberkurvenscheibenantrieb Farbheberkurvenscheibe is thus driven exclusively by the Farbheberkurvenscheibenantrieb or driven by the Exzenterlagerantrieb roller cam is thus exclusively driven by the Exzenterlagerantrieb.

The drivable by the ink fountain roller drive first inking roller is preferably not directly driven by the main drive assembly, but at most only indirectly by friction on the directly driven by the main drive assembly rollers. The Farbheberkurvenscheibenantrieb drivable Farbheberkurvenscheibe is preferably not directly driven by the main drive assembly, but at best only indirectly by friction on the directly driven by the main drive assembly rollers. The driven by the eccentric bearing roller cam plate is preferably not directly driven by the main drive assembly, but at best only indirectly by friction on the directly driven by the main drive assembly rollers.

The ink fountain roller drive is preferably arranged coaxially with the first inking roller to ensure the immediate drive of the first inking roller by the ink fountain roller drive. The Farbheberkurvescheibenantrieb is preferably coaxial with the Colourlift cam disc arranged to provide immediate drive of the color lifter cam by the color lifter cam drive. The eccentric bearing drive is preferably arranged coaxially to the roll cam to ensure the direct drive of the roll cam by the eccentric bearing drive.

The work preferably includes a color lifter. The ink lifter is designed for contacting the ink fountain roller drive drivable by the first inking roller to allow immediate color transport from the ink lifter to the drivable by the ink fountain roller drive first inking roller.

Preferred embodiments of the work include further of the inking rollers, which are not directly or indirectly driven directly by the further drive, but in particular by the main drive assembly. Preferably, only that of the inking rollers by the further drive, in particular by the ink fountain roller drive, can be driven directly, which is designed for contacting the ink lifter and is arranged immediately following the color transfer lifter. This inking roller is the first inking roller.

Alternatively preferred embodiments of the work include further of the inking rollers, which are also driven by the further drive, in particular by the ink fountain roller drive. Apart from that, further of the rollers or cylinders of the movement can also be driven by the further drive or by the ink-roller drive.

In preferred embodiments of the factory, the drive of the Farbheberkurvenscheibe, for pivoting or clocking the color lifter. The Farbheberkurvenscheibe converts the rotational kinematics of the further drive in a translationally non-uniform clocked movement of the ink lifter.

In the first preferred embodiment described above and in the second preferred embodiment described above, in which one of the further drives is complementary to the drive of the first rotatable inking roller, driving the Farbheberkurvenscheibe and / or driving the roller cam of the eccentric bearing, the plant preferably comprises a torque-transmitting connection for transmitting a torque from the further drive to the first rotatable inking roller, to the Farbheberkurvenscheibe or on the Walzenkurvenscheibe. This torque-transmitting connection is preferably formed by a belt transmission, which is preferably designed as a toothed belt transmission. A belt of the belt drive or a toothed belt of the toothed belt drive spans the axis of the inking roller, the axis of the Farbheberkurvenscheibe and the axis of the Walzenkurvenscheibe or at least two of said axes.

In alternative preferred embodiments, in addition to the main drive assembly and the ink fountain roller drive the Farbheberkurvenscheibenantrieb continues to drive the Farbheberkurvenscheibe available, which can be used as an alternative to Farbreiberwalzenantrieb.

In modified embodiments, the further drive, for example, the Farbheberkurvenscheibenantrieb for driving further of the rotatable rollers and / or cylinders of the factory is formed.

The roller immediately following the first inking roller is designed to contact the first inking roller. The roller immediately following the first inking roller is preferably formed by a loading roller or by a transfer roller.

The first inking roller immediately downstream roller is preferably mounted in the eccentric bearing, by which a rotational axis of the first inking roller immediately downstream roller between a set position and a parking position is displaceable. In the parking position, a functional gap is formed between the first inking roller and the roller immediately following the first inking roller, whereas in the setting position the first inking roller and the roller immediately following the first inking roller are arranged in contact. The functional gap is preferably less than 0.5 mm; more preferably less than 0.1 mm. The function gap is greater than zero because it is a gap. The functional gap is preferably greater than 0.01 mm. The parking position is preferably selected in the time phases when the ink lifter contacts the first inking roller, so that a transfer of the lifter stroke is largely prevented. The alternating deflection into the setting position and in the parking position preferably takes place synchronously with the clock of the color lifter.

An alternative preferred embodiment of the work comprises a linear actuator, by which the eccentric bearing of the first inking roller immediately downstream roller between the setting position and the parking position is deflected. However, the eccentric bearing of the roller immediately following the first inking roller is particularly preferably deflectable by the roller cam between the setting position and the parking position, wherein the roller cam can be driven by one of the further drives. For this purpose, the plant preferably includes one Torque transmitting connection for transmitting a torque from the further drive on the roller cam. This torque-transmitting connection is preferably formed by the belt transmission or toothed belt transmission described above. The belt of the belt drive or the toothed belt of the toothed belt drive thus spans the axis of the inking roller, the axis of the Farbheberkurvenscheibe and the axis of the roller cam. In an alternative preferred embodiment, the roller cam is driven by the Farbheberkurvenscheibenantrieb so that the Farbheberkurvenscheibenantrieb the eccentric bearing of the first inking roller immediately downstream roller between the set position and the parking position can deflect.

The first inking roller and the roller immediately downstream of the first inking roller are preferably driven at a same peripheral speed, which can be reliably ensured by the inventive presence of the main drive assembly and the further drive.

In an alternative preferred embodiment, the first inking roller is mounted in an eccentric bearing, by which a rotational axis of the first inking roller between the above-described setting position and the above-described parking position is displaceable.

In a further preferred embodiment, the ink fountain roller drive is designed so that further of the rotatable rollers and / or cylinders of the factory are alternatively drivable by the ink fountain roller drive.
