Abstract
The present invention discloses an automated rock saw having a saw motor load sensor to control the speed of the conveyor bringing the rock to the saw blade. As the saw motor works harder to cut a given rock, the controller automatically slows the conveyor belts, reducing the load on the saw blade. If the saw blade is easily cutting a given rock and not working at optimum speed, the conveyor will be sped up, increasing production. Also provided in an alternate embodiment is a horizontal blade that can be moved into place to cut the “bottom” of a corner piece, then the standard, vertical blade cuts the other side of the corner.
Claims10
An automatic rock saw comprising:
- a frame;
- a blade operatively attached to the frame;
- a blade motor mounted on the frame and operatively attached to the blade to power the blade;
- a conveyor having rollers and a conveyor belt to convey material to be cut to the blade, said conveyor mounted on the frame such that the conveyor belt is substantially perpendicular to the blade;
- a conveyor motor mounted on the frame and operatively attached to the conveyor to power the conveyor;
- a sensor attached to the blade motor to electronically detect load on the blade motor;
- and
- a controller to control the speed of the conveyor motor based on an inverse relation to the load on the blade motor, the controller being electronically connected to the sensor.
An automatic rock saw comprising:
- a frame;
- a circular blade means attached to the frame functioning to cut a desired material;
- a blade motor mounted on the frame and operatively attached to the blade to power the circular blade means;
- a conveyor means substantially perpendicular to the circular blade means functioning to convey material to be cut to the circular blade means mounted on the frame;
- a conveyor motor mounted on the frame and operatively attached to the conveyor means to power the conveyor means;
- a sensor means attached to the blade motor to electronically detect load on the blade motor;
- a controller means electronically connected to the sensor means to control the speed of the conveyor motor and functioning to vary the speed of the conveyor motor based on the load on the blade motor.
