System for inventory management
The present invention relates to a system for detecting and communicating the position of a pusher assembly on a shelf. In an embodiment, a system includes a control module, a pusher assembly, and a laser scanner. The laser scanner is configured to transmit a swept beam to a mirrored reflective surface located behind the pusher assembly. The control module analyzes the laser beam at the laser scanner to detect the position of the pusher assembly on the shelf. In another embodiment, a system includes a control module, a pusher assembly, and an infrared transceiver that sends and receives infrared signals. The transceiver may be located behind the pusher assembly. The control module analyzes the infrared signals to determine the position of the pusher assembly on the shelf.
1. A system for detecting and communicating the position of a pusher on a shelf comprising:
a divider wall,
a pusher,
a floor configured to receive product,
a sensing device mounted to one of the divider wall or the floor; and
a processor being configured to receive information regarding the interaction between the pusher and the sensing device, to determine the approximate number of products on the shelf based on the interaction between the pusher and the sensing device, and to determine the movement of the pusher and a rate of change in a product level; and
wherein the processor is configured to provide notification when a deviation in the typical movement of the pusher and the rate of change of the product level has occurred.
2. The system of claim 1 further comprising placing a plurality of sensing devices on either the divider wall or the floor.
3. The system of claim 1 wherein the processor is configured to determine the approximate distance between the pusher and a front of the shelf.
4. The system of claim 2 wherein when the products are placed over the plurality of sensing devices, the plurality of sensing devices are closed and as products are removed and as the pusher travels in a forward direction, the plurality of sensing devices are released and opened.
5. The system of claim 2 wherein a controller determines which sensing devices are open or closed.
6. A method for approximating the amount of products on a shelf having a pusher comprising:
placing a sensing device on a surface below the pusher, above the pusher, or adjacent to a side of a pusher;
sending information regarding an interaction between the pusher and the sensing device to a processor; and
determining the approximate position of the pusher in relation to a front of the shelf based on the interaction of the pusher and the sensing device; and
wherein the processor is configured to determine the movement of the pusher and a rate of change in a product level and to provide notification when a deviation in the typical movement of the pusher and the rate of change of the amount of products has occurred.
7. The method of claim 6 further comprising placing a plurality of sensing devices along and adjacent to a traveling path of the pusher.
8. The method of claim 6 further comprising determining the approximate number of products that are on the shelf.
9. The method of claim 7 wherein when the products are placed over the sensing devices, the sensing devices are closed and as products are removed and as the pusher travels in a forward direction, the sensing devices are released and opened.
10. The method of claim 7 wherein a controller determines which sensing devices are open or closed.
