SYSTEMS AND METHODS FOR SENSOR CONTROLLED REACH CARRIAGE |
摘要 |
Automated systems and methods control the velocity of the extension arm of a reach carriage. In particular, the extension arm is allowed to operate at full velocity when it is not approaching its extension or retraction limits. At the limits, the extension arm is gradually slowed to a stop. A sensing apparatus includes a sensor and a marker that moves with the movement of the extension arm. The marker moves into and out of the sensor's range, causing the sensor to generate a position signal. If the extension arm is nearing its limit, the marker is outside the sensor range. A control unit detects changes in the position signal and slows the extension arm accordingly. The control unit may apply a deceleration profile to cushion the extension arm at its limits. |
