What Is a Cam Positioner?
A cam positioner is a machine that electrically realizes the function of a mechanical cam.
A cam is a mechanical element that has a structure to change the direction of motion, for example, from rotary motion to linear motion.
Mechanical cams used in manufacturing plants, for example, have a physical structure that causes a specific action in response to the angle of rotation.
On the other hand, a cam positioner is an electronic device that receives input from a resolver, absolute encoder, or other devices that detect the angle of rotation and outputs a set signal.
Uses of Cam Positioners
Cam positioners are mainly applied to the control of industrial machinery.
Cam positioners has multiple cam banks, and the ON/OFF signal for cam output is programmed for each angle. By turning on the operating signal of the cam positioners, it outputs signals according to the programmed signals in response to the input signals from the angle detector.
In manufacturing plants, this system is used to control equipment with different functions depending on the angle on a line that involves rotation. For example, they are used to automate operations that involve multiple processes, such as pouch filling and packaging machines.
Principle of Cam Positioners
Cam positioners were created as a device to replace mechanical cams. It is necessary to realize multiple controls using the rotation angle, which is the physical state of the target device, as an input signal. For this purpose, the cam positioners consists of two lines of inputs and multi-channel output.
One of the inputs is a control signal for starting the cam positioners and specifying the origin. The other is a signal from the detector that detects the rotation angle.
The detector, a resolver, consists of two orthogonal fixed windings and a rotating winding. The fixed windings carry currents of different phases, and the angle of rotation is calculated by examining the phase of the voltage in the rotating windings induced by the currents.
Another detector, the absolute encoder, uses a light-receiving sensor and a magnetic sensor to detect the angle of rotation of the drive. The two input signals are processed by the cam positioners and output to a channel for each cam bank where the ON/OFF program is recorded. The output signals are input to the output monitor and the control unit of each device.
