Definitions

  • the invention relates to a drive coupling for connecting a drive shaft with an interchangeable cylinder of a printing press.
  • Robots are known with which the mostly relatively heavy cylinders can be lifted out of their bearings in the machine frame after the corresponding bearing caps have been opened or removed. If the cylinder is driven by meshing gears, so the meshing is automatically canceled when the cylinder is lifted out of its bearings. Lately, however, have been increasing Drive systems are used in which the cylinders and rollers are one Printing press does not have gear transmission synchronized with the help of a single one Drive motor are driven, but a separate one for each cylinder Drive motor is provided, which is directly on a coaxial with the relevant cylinder connected drive shaft sits.
  • Document US-A-4 645 373 discloses a drive clutch with a clamping piece arranged on the drive shaft, the one has a radially opening recess in the end of the cylinder arranged locking part can be guided in a form-fitting manner.
  • the object of the invention is to provide a drive clutch, on the one hand a precise direct drive of the cylinder and on the other hand a simple one Exchange of the cylinder permitted.
  • a locking part is provided and that in or on the drive shaft a clamping piece is arranged, which has a radially opening recess has, in which the locking part is positively insertable, and that Clamping piece is axially retractable to the cylinder with the help of the locking part pull against one end of the drive shaft.
  • the cylinder is closed using the Clamping piece axially clamped against the end of the drive shaft, so that a positive or preferably predominantly non-positive connection is created between the drive shaft and the cylinder.
  • the clamping piece With a change of cylinders the clamping piece is extended into a release position, in which exit the locking part radially from the recess of the clamping piece can.
  • the cylinder can thus be very easily removed from the drive shaft be uncoupled by using the robot radially in the direction is moved in which the recess of the clamping piece opens.
  • the new cylinder can then perform this sequence of movements with its Bolt part inserted into the clamping piece and then by pulling back the Clamping piece can be clamped again against the end of the drive shaft, so that the drive connection is restored.
  • the drive clutch according to the invention is particularly for printing presses provided in which the drive coaxially with the cylinder connected drive shaft takes place, the storage of the cylinder in the machine frame but is done directly on the cylinder. Because in this case the bearings are one have a relatively large diameter, the drive coupling, which is natural must have a certain minimum diameter, immediately connect to the bearing of the cylinder or even something in that engage the front end of the cylinder, so that a very small Construction is achieved. Furthermore, it proves advantageous that the Cylinder axially clamped to the drive shaft by the drive coupling becomes. The coupling therefore behaves in the axial direction and in the direction of rotation stiff, so that a precise adjustment of the side register and the longitudinal register is made possible.
  • the clutch can do something to be compliant.
  • This has the advantage that the axis of rotation of the cylinder is precise is defined by the storage in the machine frame and a minor. eccentricity of the drive shaft due to mounting inaccuracies can be compensated, as in the European patent application 98 121 059 of the applicant.
  • the mutually facing ends of the cylinder and the drive shaft preferably form together a friction clutch, which in a particularly preferred Embodiment with a positively engaging coupling, in particular a one-tooth clutch is combined.
  • a friction clutch which in a particularly preferred Embodiment with a positively engaging coupling, in particular a one-tooth clutch is combined.
  • the Single-tooth clutch to the cylinder in a defined angular position with respect to the drive shaft to keep the setting of the longitudinal register with the help of one arranged on the drive shaft or directly on the motor Angle sensor can take place The transmission of the drive torque. However, this is mainly done through the friction clutch.
  • the clamping piece is preferably elastically biased into the clamping position and with the help of an actuating rod running axially through the hollow drive shaft movable into the release position. If the drive shaft is coaxial with is connected to the motor shaft or is formed in one piece with it, the actuating rod can extend through the entire motor and possibly also extend the angle sensor. Then to release the clutch the free end of the operating rod by a pneumatic or hydraulic actuated plunger are applied to the rotation of the drive shaft does not need to participate.
  • Figure 1 is one end of a cylinder 10, for example a printing cylinder or an application roller of a printing press, which is shown with the help the drive clutch shown in Figure 3 coupled to a drive shaft 12 shall be.
  • An end section of the cylinder shown in section in FIG. 1 10 forms a bearing surface 14 and serves to store the relevant one End of the cylinder 10 in a bearing 16 ( Figure 3), which is not in one shown frame of the printing press is arranged.
  • Friction ring 18 arranged at a point on its circumference by a projecting Clutch tooth 20 is interrupted.
  • a cylindrical extension projecting coaxially from the end of the cylinder 10 22 carries at the free end a locking part 24 which, as can be seen in FIG is in the shape of a circular disc.
  • the drive shaft 12 shown in FIG. 3 carries on its bearing 16 facing End a friction ring 26 which, when the cylinder 10 is coupled, forms a friction clutch together with the friction ring 18 of the cylinder.
  • the friction ring 26 is interrupted at one point on its circumference by a notch 28, in which the clutch tooth 20 can engage with a perfect fit, so in the engaged state, the angular position of the cylinder 10 precisely with respect is fixed to the angular position of the drive shaft 12.
  • the drive shaft 12 is designed as a hollow shaft and is axially by one continuous operating rod 30 penetrates.
  • a clamping piece 32 is attached, which is by means of the actuating rod 30 is axially displaceable in an end section of the drive shaft 12.
  • the clamping piece 32 has a U-shaped recess 38 in cross section, which is opens radially in the direction of the notch 28, upwards in FIGS. 3 and 4.
  • the Recess 38 is at the free end of the clamping piece through an end wall 40 limited, in which also a U-shaped opening upwards Slot 42 is formed.
  • the actuating rod 30 has on its opposite the clamping piece 32 End a plate 44 and is left by a spring 46 in Figure 3 biased so that it has a tendency to the clamping piece 32 in the Retract interior of drive shaft 12.
  • the plate 44 is actuated pneumatically or hydraulically Tappet 48 held in position against the force of spring 46 in which protrudes the clamping piece 32 from the open end of the drive shaft 12. If in this state the cylinder 10 using a not shown Robot is inserted into the bearing 16 from above, the locking member 24 enters the recess 38, and the extension 22 lies in the slot 42 of the End wall 40.
  • the state is shown in FIG. 5.
  • the plunger 48 is then withdrawn so that the spring 46 relaxed and the operating rod 30 and the clamping piece 32 to the left shifts.
  • the locking part 24 of the end wall 40 of the clamping piece 40 is detected, and the cylinder 10 is axially in the bearing 10 against the End of the drive shaft 12 pulled so that the friction rings 26 and 28 firmly together brought into frictional contact, as shown in Figure 6.
  • the Coupling tooth 20 enters the corresponding notch 28.
  • a connection is rigid in the axial direction and in the circumferential direction created between the drive shaft 12 and the cylinder 10.
  • the drive shaft 12 of which in the drawing only the respective end sections are shown, can also be the rotor of a drive motor, not shown form so that the drive shaft 12 and also the actuating rod 30 axially pass through the housing of this drive motor.
  • a mechanism can also be on the drive shaft 12 attack to adjust the side register, and into the engine can an angle sensor for measuring the angular position of the cylinder 10 for adjustment of the longitudinal register. All adjustment movements for adjustment of the longitudinal and side register are by the invention Transfer the drive clutch to the cylinder 10 without play.
  • the bearing 16 is closed with the aid of a bearing cover 50.
  • the axis of rotation of the cylinder 10 is then precise through the frame fixed Camp 16 defined. If it is due to dimensional tolerances in the manufacture or mounting the motor housing to a slight eccentricity between the drive shaft 12 and the cylinder 10 comes, this eccentricity be compensated for in that the friction rings 26 and 18 radially somewhat work against each other.
  • the clutch tooth 20 also only engages in the circumferential direction free of play, but in the radial direction with play in the corresponding notch the drive shaft. In this way the transmission of radial forces and / or bending moments on the cylinder 10 prevented.
  • the bearing cap 50 opened or removed, and the operating rod 30 is by means of Ram 48 moved back to the release position.
  • the front wall can 40 of the clamping piece 32 engage on the end face of the cylinder 10 and move the cylinder to an axial position in which the locking member 24th is outside the drive shaft 12 so that the cylinder 10 with the help a robot can lift up out of the bearing 16.
