Abstract
A method of controlling the travel speed of a unit in a machine for processing printing materials, including monitoring the travel speed by a first measuring device, includes additionally monitoring the travel speed by a second measuring device belonging to the machine; a control device for performing the method; and a machine for processing printing materials having the control device.
Claims14
A method of controlling the travel speed of a unit in a machine for processing printing materials, which comprises:
- monitoring the travel speed by a first measuring device;
- and
- additionally monitoring the travel speed by a second measuring device belonging to the machine.
A device for controlling the travel speed of a unit in a machine for processing printing materials, the unit having end positions, the device comprising:
- a travel path having a length limited by the end positions of the unit;
- a motor for driving the unit along said travel path, said motor being activatable as a function of instantaneous travel positions of the unit;
- and
- a relative rotary encoder for registering the instantaneous travel positions, said relative rotary encoder having a rotor with a circumferential range of 360°, said circumferential range being a measuring representation of only a portion of said length.
A machine for processing printing materials, comprising:
- a unit having end positions;
- a device for controlling a travel speed of said unit, said device defining a travel path having a length limited by the end positions, said device having a motor for driving said unit along said travel path, said motor being activatable as a function of instantaneous travel positions of said unit;
- and
- a rotary encoder for registering said instantaneous travel positions, said rotary encoder being constructed as a relative rotary encoder, said relative rotary encoder having a rotor with a circumferential range of 360°, said circumferential range being a measuring representation of only a portion of said length.
A device for controlling the travel speed of a unit in a machine for processing printing materials, the device comprising:
- a motor for driving the unit, the motor being activatable as a function of instantaneous travel positions of the unit;
- and
- a relative rotary encoder for registering the instantaneous travel positions, said relative rotary encoder having a rotor to be connected to the unit so that, while the unit moves from one end position to an opposite end position of the unit, said rotor executes a plurality of complete revolutions.
