Abstract: A tracking apparatus which can ensure good-accuracy coincidence between a conveyed material and a tracked position thereof, even when slip occurs in the conveyed material moving across conveyance tables. A sensor is located at a boundary position of a conveyance table, of conveyance tables arranged adjacent to each other, to detect the presence or absence of a conveyed material. Head and tail end tracking data of the conveyed material is generated, and positions of head and tail ends are calculated using conveyance speed of a selected conveyance table as a speed standard. Then, occurrence or nonoccurrence of slip of the conveyed material is determined from the detection signal of the sensor and the positions of head and tail ends. When slip has occurred, head and tail end tracking data generation is stopped. Head and tail end tracking data generation is restarted considering a time delay due to removal of chattering from the detection signal.

The first and second communicating ports are respectively mounted inside openings on the opposite sides of the casing, so a wire is connected between the first and second communicating ports on opposite sides of the adjacent two drive roller controllers. Therefore, the wire is not easily protruded outside the accumulating conveyor unit, so the connection of wire and the drive roller controller is not easily disconnected.

Abstract: A drive controller for controlling movement of a plurality of packages by an accumulation conveyor.

Blockage of the sensor in an upstream zone before the sensor in a downstream zone indicates an oversized package that extends longer than a zone length of the downstream zone and into the upstream zone. The drive controller is configured to drive the downstream zone and upstream zone simultaneously when detecting the oversized package.
