Abstract

A drive system for driving a belt is presented. The system comprises a frame, a driving shaft connected to a motor, a controller, a driven shaft, two pulleys connected to the driven and driving shafts, and a belt. The frame supports the driving and driven shafts to mount the belt on the pulleys. A signal element is mounted on and drives with the belt. At least two detection elements are mounted on the frame so that when the signal element passes the detection elements, a signal is generated as the belt moves. The detector elements are connected to a controller which controls the motor so that when the system starts, the belt moves until the signal element generates a signal in a first detector element to fix a zero point of the belt movement. The signal of the second detector element checks the zero point during normal drive operation.

Dependent claims

A belt drive system for driving a belt, the belt drive system comprising:

a frame;
a driving shaft connected to a motor;
a controller;
a driven shaft;
two pulleys connected to the driven shaft and driving shaft respectively;
a belt, wherein the frame supports the driving shaft and driven shaft so that the belt is mounted on the pulleys;
a signal element mounted on the belt so that the signal element drives with the belt;
and
at least two detection elements mounted at the frame so that when the signal element passes by the detection elements, a signal is generated by the passing by of the signal element, wherein the detector elements are connected to the controller, wherein the controller is configured to control the motor so that in a starting operation of the belt drive system, the belt moves until the signal element generates a signal in a first detector element of the at least two detector elements to fix a zero point in space of the belt movement, wherein the controller is configured to receive and use the signal of the second detector element to check the zero point in space during normal operation of the belt drive system.
