Embodiment Construction

[0048] figure 1 A typical multi-shelf refrigerated beverage merchandising unit (RBMU) 1 is shown, comprising a light source 2 positioned at the front of the unit to illuminate a stack of four shelves 3 . Four photosensitive elements 5 are fixed to the rear wall 4 of the unit, with each sensor being located at an intermediate height between one shelf and the shelf above. Four sensor covers 6 are connected to the rear wall 4 over each sensor 5 such that each cover 6 provides a cover over each sensor 5 .

[0049] figure 2 The arrangement of sensors 5 and associated shrouds 6 on a fully stocked shelf 3 in RBMU1 is shown. Rack 3 is a slatted rack comprising a plurality of parallel bars running horizontally from the front of RBMU 1 to rear wall 4 . The shelf 3 is fully stocked with beverage cans 7 .

[0050] Light source 2 is located at the right front corner of RBMU1 and sensor 5 is located at the opposite corner. A shroud 6 , shown in outline and having a quarter circle, is ...

Abstract

Disclosed is a sensor shield (6, 6a, 6b) for use in a multi-shelf merchandise display unit (1) including a plurality of sensors (5, 5a, 5b) mounted on a wall (4) of the unit (1) and opposite a source of illumination (2), in which each sensor (5, 5a, 5b) corresponds to a single shelf (3, 3a, 3b) and in which the shelves (3, 3a, 3b) are at least semi-porous to the illumination. The shield (6, 6a, 6b) comprises i) a plate having a length that is sufficient substantially to reduce or prevent incident illumination from the shelf (3, 3a, 3b) above reaching the sensor (5, 5a, 5b); and ii) means (26) n to attach the plate to casing of or around the sensor (5, 5a, 5b) or the wall (4) of the unit (1). The plate is opaque to the illumination detected by the sensor (5, 5a, 5b). Also disclosed is a method to reduce the interference of light in a multi-shelf merchandise display unit (1) from shelves (3, 3a, 3b) above a shelf (3, 3a, 3b) on which stock levels are being measured and a method for monitoring stock levels in a retail display cabinet by measuring light entering the retail display cabinet.

Description

technical field [0001] The present invention relates to the implementation of accurate stock level predictions in automated goods display cabinets, such as cold beverage cabinets. Background technique [0002] Glass-fronted cargo units are used throughout the world and typically include multiple horizontal or sloped shelves that store and display items for sale. Typically, such cabinets or units are used to store and dispense items at the point of sale by sales clerks or other store employees, either as part of a vending machine or as part of a point of sale display rack directly accessible to consumers. The cabinet or unit includes the display and presentation of virtually any type of product typically presented to consumers in cases, boxes, wrappers, bags, etc. storage. [0003] Glass-fronted cargo cabinets and units are used in stores, such as convenience stores, to store and dispense merchandise for sale, providing consumers with self-service options or storage and dis...
