Description

Refrigerated Sales Furniture
The invention relates to a refrigerated sales furniture, in particular to a refrigerated sales furniture comprising at least one identification device, which is configured for identifying products while they are put into and/or taken out of the refrigerated sales furniture.
Refrigerated sales furnitures such as refrigerated sales cabinets and refrigerated sales islands provide the bridge between retailers and consumers.
It therefore is desirable to provide specific information about the products stored within those furnitures. Even scanning and registering the products, which are sold, at the cashier devices, cannot provide detailed and reliable information about the current stock, as scanning the products at the cashier devices does not provide specified real time information for each furniture.
It therefore would be beneficial to provide an improved refrigerated sales furniture, which allows to keep track of its contents, i.e. of products put into and taken out of the furniture, in real-time.
According to an embodiment of the invention, a refrigerated sales furniture comprises a furniture body providing a refrigerated sales space for storing products to be presented therein; at least one access area providing access to the refrigerated sales space; and at least one identification device, which is arranged and configured for identifying products passing through said at least one access area.
According to an embodiment of the invention, a method of operating a refrigerated sales furniture is provided. The refrigerated sales furniture comprises a furniture body providing a refrigerated sales space for storing products to be presented therein; and at least one access area providing access to the refrigerated sales space. The method comprises the step of identifying products passing through the at least one access area. A refrigerated sales furniture and a method of operating a refrigerated sales furniture according to exemplary embodiments of the invention allow to reliably keep track of the contents of the refrigerated sales furniture by identifying all products, which are put into and taken out of the refrigerated sales furniture, in real-time.
The information provided by a refrigerated sales furniture comprising at least one identification device according to an exemplary embodiment of the invention may be used for generating statistics of movements and stocks of individual products for each furniture.
Exemplary embodiments will be described with reference to the enclosed figures:
Figure 1 shows a schematic perspective view of a refrigerated sales furniture according to an exemplary embodiment of the invention.
Figure 2 shows a schematic perspective view of a compartment of a refrigerated sales furniture according to an exemplary embodiment of the invention.
Figure 3 shows an enlarged view of a product reader bar, as it is shown at the front edge of the upper shelf of Figure 2.
Figure 1 shows a schematic perspective view of a refrigerated sales furniture 2 according to an exemplary embodiment of the invention.
In Figures 1 to 3 a refrigerated sales cabinet is shown as an example of a refrigerated sales furniture 2. The refrigerated sales furniture 2 typically comprises a plurality of refrigerated sales spaces 5a-5e, which are configured for storing products 20 to be presented therein. An access area 3 providing access to the refrigerated sales spaces 5a-5e is formed by the upright front portion located in front of the refrigerated sales spaces 5a-5e of the refrigerated sales furniture 2. A plurality of shelves or racks, which are not shown in Figure 1 , may be provided within the refrigerated sales spaces 5a-5e for accommodating and supporting the products 20 to be stored.
The skilled person, however, will easily understand that the invention may be applied to other types of refrigerated sales furnitures 2 as well, for example to refrigerated sales islands or refrigerated sales chests, in which the products 20 to be presented therein are stored on a bottom portion thereof and in which the access area providing access to the refrigerated sales space is formed by the upper horizontal portion of the refrigerated sales island or chest, which is located above the refrigerated sales space.
The refrigerated sales furniture 2 shown in Figure 1 has a furniture body and comprises a plurality of compartments 4a-4e positioned adjacent to each other. Each of the plurality of compartments 4a-4e defines at least one refrigerated sales space 5a-5e. The refrigerated sales spaces 5a-5e may be equipped with a plurality of shelves or racks 10a, 10b, which are not shown in Figure 1. The shelves 10a, 10b may be arranged on top of each other in the refrigerated sales space 5a-5e for receiving and supporting products 20, which are to be stored within the refrigerated sales furniture 2.

The cap 14 protects the at least one camera 6a, 6b, 6c, RFID readers 6d, 6e, 6f and/or the at least on illumination device 7 from adverse effects, in particular from being hit and damaged by products 20 placed into or taken out of the refrigerated sales furniture 2.
A number of optional features are set out in the following. These features may be realized in particular embodiments, alone or in combination with any of the other features.
In an embodiment, the at least one identification device comprises at least one camera, which is configured for capturing pictures of products passing the at least one access area, and at least one identification unit, which is configured for identifying the products passing through the at least one access area from the pictures captured by the at least one camera, based on the optical properties of said products. Said optical properties in particular may include the size/volume, the shape, and/or the color of the product or its packing, respectively. This allows to identify each product by its inherent properties. In consequence, there is no need to add additional markers such as barcodes, QR-codes etc. to the product. When using such optical properties for identifying the products passing through the at least one access area, appropriate image processing techniques and appropriate comparison techniques of such processed images with reference images stored for each product in one or more appropriate data bases may be used.
In an embodiment, the identification device is configured for identifying the products based on an optical code provided on the respective product. The code may be a usual barcode (e.g. one of the EAN, UPC, IAN and JAN codes), which already is provided on almost every product intended for sale. The code also may be an additional/new code, in particular a two-dimensional code, e.g. a QR-code, which is configured to be identified faster, more easily and/or more reliably than a barcode. An optical code allows a very reliable and unique identification of the products.
When using such optical code provided on the respective product for identifying the products passing through the at least one access area, the captured codes may be associated to reference codes stored for each product in one or more appropriate data bases.
The identification of an optical code attached to the product also may be used for confirming a previous identification, which has been made based on the size/volume, the shape and/or the color of the product or its packing. The optical code may be printed directly onto the product or its packing. Alternatively, the optical code may be printed on a label, which is attached to the product or its packing.
In an embodiment, the identification device is configured as a barcode reader which is configured for identifying the products based on a barcode, which is attached to each of the products.
In an embodiment, the identification device is configured as a QR-code reader for identifying the products based on a QR-code, which is attached to each of the products. In an embodiment, the identification device is further configured for identifying additional information provided by the identified product or its packing. Said additional information in particular may include the production date and/or the best before date of the respective product. Identifying and keeping track of such information allows to optimize the stock-keeping even further. In particular, products may be taken out of the refrigerated sales furniture just before or at the best before date or after the best before date has passed and new products replacing said products may be ordered automatically or manually in due time.
In an embodiment, the cameras and the identification unit are configured for detecting whether the doors are completely closed. This allows the identification unit, the tracking unit or a special door monitoring unit to issue an alarm signal in case at least one of the doors is not completely closed for more than a predetermined period of time and helps to avoid that energy is wasted by operating the refrigerated sales furniture with the doors not being completely closed for a substantial period of time.
In an embodiment, the refrigerated sales furniture comprises at least one illumination device, which is configured for illuminating the products passing through the at least one access area. By illuminating the products passing through the at least one access area the reliability of identifying products passing through the at least one access area based on their optical properties may be considerably enhanced. The illumination device in particular may provide white light comprising all colors of the spectrum in order to facilitate the identification of the products based on their respective color(s). Optionally, the illumination device may provide IR-light and/or UV-light, which may be reflected by corresponding reflectors attached to at least some of the products.
In an embodiment, the at least one identification device comprises at least one RFID reader and at least one identification unit, which is connected with the at least one RFID reader. In such an embodiment the products may be uniquely identified by means of RFID tags which are attached to the respective product. RFID tags allow a reliable and unique identification of the products.
In an embodiment, the at least one access area is an open access area providing free access to the refrigerated sales space. An open access area is very convenient for the costumers, as it does not require the costumers to open doors or flaps for accessing the products stored within the refrigerated sales space of the furniture.
In an embodiment, the refrigerated sales furniture comprises at least one door or flap, which allows for closing the access area. Providing a door or flap closing the access area reduces the energy needed for operating the refrigerated sales furniture, i.e. for cooling the refrigerated sales space, as warm air is prevented from entering into the refrigerated sales space and refrigerated air is prevented from flowing out of the refrigerated sales space when the at least one door or flap is closed. The at least one door or flap may be at least partially transparent for allowing customers to look into the refrigerated sales space without opening the at least one door or flap.
In an embodiment, the at least one identification device is configured to be activated when the at least one flap or door is opened, and to be deactivated when the at least one flap or door is closed. In such an embodiment, the at least one identification device is active only when the at least one door or flap has been opened for allowing products to be put into or taken out of the refrigerated sales space. As the at least one identification device is deactivated, when the at least one door or flap is closed, the amount of energy consumed by the at least one identification device is reduced. Additionally, the risk of a false identification of products is minimized as well.
In an embodiment, the refrigerated sales space comprises at least one shelf or rack which is configured for receiving and supporting products to be stored. At least one camera and/or at least one RFID reader may be mounted to said at least one shelf. Installing at least one camera and/or at least one RFID reader at a shelf provided within the refrigerated sales space allows to identify the products put onto and taken from said shelf or an adjacent shelf, which is arranged above or below the shelf the camera and/or the RFID reader is attached to. Such a configuration in particular allows to identify products based on the shelf they are taken from. It further allows to provide more detailed product movement and product stock statistics, which in particular may include information related to the location of the products within the furniture.
In an embodiment, the refrigerated sales space is provided with a plurality of regions which are cooled to different temperatures, e.g. cooling temperatures above 0 °C and freezing temperatures below 0 °C, in particular below -10 °C. In this configuration, providing an identification device at every shelf allows to verify whether each product is placed on a shelf in the correct temperature region.
In an embodiment, the refrigerated sales furniture is configured for determining the region or the shelf in/on which the product is placed, e.g. by determining the portion of the access area through which the product is passed.
In an embodiment, the refrigerated sales furniture is configured for triggering an alarm when a product is placed into a wrong temperature region or onto a wrong shelf within the refrigerated sales space. This helps to avoid products from being spoiled or damaged by being placed into a wrong area of the refrigerated sales space, in particular into an area, in which the temperatures are too high or too low for the respective product.
In an embodiment, at least one camera and/or at least one RFID reader is installed above at least one shelf and/or at least one camera and/or at least one RFID reader is installed at an edge of said shelf. Installing at least one camera and/or at least one RFID reader above and/or at the edge of the shelf allows the at least one identification device to reliably identify a product, which is put into and/or taken out of the refrigerated sales space.
In an embodiment, the at least one camera and/or at least one RFID reader is installed at a front portion of a shelf and being configured to identify products which are placed onto and/or are taken from said self. In such an embodiment the detection area of the at least one camera and/or at least one RFID reader is facing basically upwards. This provides a very compact configuration, which allows to reliably identify a product, which is put onto and/or taken from such a shelf.
In order to allow the identification device to identify each product based on its inherent properties, pictures of all products, which are intended to be placed into the refrigerated sales furniture, may be stored in a storage device of the identification device. The identification device then may be configured for comparing current pictures of a product, which are provided by at least one of the cameras, with the previously stored pictures. The identification device in particular may be provided with a self-learning functionality, which allows adding additional pictures of new and/or previously known products to the previously stored pictures. In an embodiment, the refrigerated sales furniture is configured for controlling the refrigeration based on the identified products, which have been put into the refrigerated sales space. This allows to operate the refrigerated sales furniture with high efficiency, as the actual (refrigerated) temperature is adjusted to the actual needs of the products stored within the refrigerated sales space. This securely avoids the products from being spoiled as a result from being stored at wrong, in particular too high, temperatures. It further avoids the refrigerated sales furniture from consuming too much energy by providing lower temperatures than needed for storing the respective products.
In an embodiment, the refrigerated sales furniture is configured for generating an order for new products based on the products which have been identified as having been taken out of the refrigerated sales space. Thus, new products for refilling the refrigerated sales furniture may be ordered automatically before the refrigerated sales furniture is completely empty. As a result, stock-keeping is facilitated, as it is not necessary to manually check the amount or number of products, which are still present within the refrigerated sales furniture, and to order new products as soon as the number or amount of products, which are still present within the refrigerated sales furniture, has reached a certain lower limit.
In summary, the stock-keeping of refrigerated products may be considerably facilitated by employing a refrigerated sales furniture and/or a method of operating such a refrigerated sales furniture according to exemplary embodiments of the invention.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition many modifications may be made to adopt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention include all embodiments falling within the scope of the claims.
