Abstract

The invention relates to the attachment of a rotary encoder to the drive shaft of a driven by a single drive cylinder of a rotary printing machine, wherein the rotary encoder is provided with a radial support on the frame of the rotary printing machine and having a rotor which is rotatably mounted in the housing of the rotary encoder and as one on the drive shaft the cylinder plug-on and clampable hollow shaft is formed. DOLLAR A The invention is therefore based on the object, while avoiding an elastic and thus vibration-free suspension to develop a mounting for a rotary encoder, which allows a substantial movement of the rotary encoder in the axial and radial directions, without significantly affecting the measurement results. DOLLAR A According to the invention the object is achieved in that the radial support is designed as a support lever (32) which is rigidly connected to the encoder housing (31), and the cylinder (1) facing inner edge (82) of the hollow shaft of the rotor ( 8) is associated with a conical intermediate piece (22) of the drive shaft (2).

Description

  • The The invention relates to the attachment of a rotary encoder to the drive shaft a single-drive driven cylinder of a rotary printing machine, wherein the rotary encoder with a radial support on the frame of the rotary printing machine is equipped and has a rotor which is in the housing of the Rotary encoder rotatably mounted and as a on the drive shaft of the Cylinder slip-on and clampable hollow shaft is formed.
  • such Encoders are for it determines the angular position of the drive shaft of the cylinder for Frame of the rotary printing machine to capture. This serves the single drive of the cylinder with the main drive of the machine to synchronize or to control the individual drive independently of the main drive. The rotary encoder has a housing mounted on the frame of the rotary printing press. Within of the encoder housing is designed as a hollow shaft trained rotor, with the Drive shaft of the cylinder is connectable. The rotor is with measuring disks connected, carry the angle information and scanned during the measurement process become. To axial and radial deviation between the rotor and to receive the drive shaft, the housing of the Rotary encoder floating on the frame of the rotary printing press.
  • One of these encoders will be in the DE 199 04 471 A1 described. The encoder housing is attached here with an elastic holder on the housing of the rotary printing machine. Centrally located in the encoder housing is a torsion-resistant stator, which is associated with a designed as a hollow shaft rotor. The rotary encoder is plugged with its hollow shaft on the drive shaft and clamped by a clamping device.
  • The Actuating movements of the cylinder are compensated by the elastic suspension, However, there are measurement inaccuracies.
  • From the EP 0 682 229 B1 a rotary encoder is described, which also has an elastic suspension on the frame of the machine. The clamping device for the hollow shaft of the rotary encoder is here a clamping cone, which is plugged onto the drive shaft and is pulled axially by a screw into the hollow shaft. Through the conical portion of the clamping cone, which corresponds to an inner cone of the hollow shaft, the hollow shaft is clamped on the drive shaft. Also in this solution, the elastic suspension affects the measurement considerably.
  • Of the Invention is therefore based on the object, while avoiding a elastic and thus vibration-free suspension attachment for one To develop rotary encoders, which requires a large amount of movement of the rotary encoder in the axial and radial directions, without the measurement results significantly to impair.
  • According to the invention Task by attaching the encoder with the features of 1st claim solved.
  • The Invention has the advantage that the assembly required Play between the hollow shaft and the drive shaft of the cylinder completely eliminated becomes. This is due to the centering of the drive shaft in the hollow shaft of the rotary encoder.
  • The Invention is intended to an embodiment be explained in more detail. The accompanying drawings have the following meaning:
  • 1 Schematic representation of the rotary encoder in mounted condition
  • 2 Top view 1 , Looking towards the cylinder
  • Like from the 1 and 2 can be seen, the encoder 3 on the drive shaft 2 a cylinder 1 attached to a rotary printing machine. The drive shaft 2 is in this version of one piece and consists of a wave approach 21 , a conical intermediate piece 22 and a main part 23 ,
  • In another, not shown embodiment, the conical intermediate piece 22 a separate part, indicating the drive shaft 2 is plugged.
  • The encoder 3 itself consists of a transmitter housing 31 that with a support lever 32 is firmly connected. The support lever 32 rests against one on the frame 5 the rotary printing machine arranged stop 4 off and secures the position of the encoder 3 , That is, turning the rotary encoder 3 around the drive shaft 2 of the cylinder 1 is thereby prevented. To secure the system of the support lever 32 at the stop 4 is a spring 6 (see also 2 ) intended.
  • In the encoder housing 31 is torsion-resistant to this one stator 7 arranged. Inside the stator 7 is rotatable via a shaft bearing 9 a rotor 8th stored. The rotor 8th is designed as a hollow shaft. The inner diameter a of the rotor 8th is larger than the outer diameter b of the main part 23 the drive shaft 2 , This creates a clearance fit, the easy insertion of the rotor 8th of the rotary encoder 3 allows.
  • On the cylinder 1 more distant tail 81 of the rotor 8th the wall thickness of the hollow shaft is thin-walled and allows a deformation. This area is rotatable in the stator 7 mounted clamping ring 10 associated, the three regularly offset over the circumference eccentric cam 11 wearing.
  • The inner edge 82 of the cylinder 1 facing the end of the rotor 8th corresponds with the conical intermediate piece 22 the drive shaft 2 , This inner edge 82 can also be designed as an inner cone.
  • For the operation of the device according to the invention:
    When attaching the encoder 3 on the drive shaft 2 this will go so far towards the cylinder 1 pushed until the inner edge 82 or possibly the inner cone, the conical intermediate piece 22 touched. This is the rotor 8th Centered at its cylinder-near end.
  • Thereafter, the system of the support lever 32 at the stop 4 ensured and in particular the spring 6 attached.
  • Now the eccentric socks 11 twisted and act on the tail 81 one, so that this is the cylinder-distal end of the main part 23 jammed. This clamping is due to the arrangement of the three eccentric cam 11 at the same angle to each other also centric. Further details on the design and operation are unnecessary at this point, since such clamps are part of mass-produced encoders and therefore considered to be generally known.
  • The Measurement can now take place.
