Automatic assembly machine feeder for transmitting elements stored in element conveyor belt to pick-up position, has estimating unit estimates signal of sensor device, where estimating unit clearly identifies needle wheel tooth

摘要

The feeder has a needle wheel tooth (Z1) comprising an identifiable width and/or an identifiable height. Gaps are formed between a needle wheel tooth (Z) and the needle wheel tooth (Z1) with an identifiable depth. A driver (AT) i.e. stepper motor, drives a needle wheel (S) to move, and a sensor device (SE) i.e. fork-shaped photoelectric grid, scans the needle wheel teeth. An estimating unit (AW) estimates a signal of the sensor device, where estimating unit clearly identifies the needle wheel tooth (Z1) and the sensor device generates signals. An independent claim is also included for a method for locating elements on a pick-up position in a feeder.
