Abstract
A shoe sorter is described. The shoe sorter can include a switch plate that supports movement of a shoe pin of a pusher shoe, a finger, and an actuation arm. In some examples, the finger can be configured to be moved in a first direction in response to a portion of the shoe pin contacting a portion of the finger. The actuation arm can be pivotably engaged to the finger so that a movement of the finger in the first direction can cause a movement of the actuation arm in a second direction. In this regard, the actuation arm in the second direction can cause a change in a signal outputted by the photoelectric sensor coupled to the shoe sorter. This change in the signal can be used by a processor to determine that the shoe pin is misaligned.
