Definitions

• This invention relates to labelling systems, and particularly, but not exclusively, to labelling systems for labelling goods carried on shelves or in elongate cabinets, for example in shops and supermarkets.
• labels carrying information such as unit price or price per unit weight, country of origin, etc, permanently printed thereon have been disposed on the front edge of a shelf or cabinet carrying the goods.
• Such labels have conventionally been in the form of flexible rectangular plastic elements held in place by engagement of upper and lower edges in respective elongate channels formed in an elongate extruded mounting strip fixed to the front edge of the shelf or cabinet.
• larger labels, carrying more information about the goods presented on the shelf or in the cabinet may be carried on individual label holders clipped or otherwise removably secured to the shelf or cabinet edge.
• each electronic label which are attachable to the front shelf edge, include an electronic display, such as an LCD panel, and receive price information to be displayed from a central computer control, which also sends the price information to the point of sale.
• Electronic communication between the price label and the central computer control may be by hard-wiring or by two-way radio link.
• each electronic label is uniquely coded and incorporates its own control electronics for controlling the label display, and for communicating bar-code and price information to and from the central computer control.
• Each individual label is ountable on an elongate track attached to the shelf front edge, and is releasably iockable thereto.
• the track incorporates elongate power lines and data bus bars, and each label has a contact shoe with contacts which engage these lines.
• this known electronic labelling system has certain disadvantages. Firstly, as with the conventional printed labelling system, alteration of the arrangement of the goods on the shelf will necessarily involve a somewhat cumbersome procedure of unlocking and removing the relevant labels and replacing them in their new positions before reprogramming them either from the central computer control or by way of an infrared link from a hand-held control device used at the position of the shelf.
• the system when assembled, presents an overall appearance which is visually markedly different from the conventional printed label system in which the continuous extrusion mounting the printed labels at their appropriate positions presents a smooth, continuous and visually pleasing appearance.
• the above-mentioned known electronic shelf labelling system when assembled, will give a broken and interrupted appearance, particularly as the individual labels are significantly wider than the track width, and project somewhat forwardly of the track.
• the present invention aims to alleviate these disadvantages inherent in the known shelf labelling systems. Accordingly, in a first aspect the present invention provides an elongate electronic labelling device for use in an electronic labelling system, the device including a visually continuous elongate display panel or screen which is operable to present separate data displays constituting respective labels at longitudinally spaced regions thereof.
• the labelling device is preferably adapted to be attached to the front edge of a display shelf unit, and to extend from one end to the other thereof.
• the device preferably comprises an elongate mounting member extruded from a suitable material, and having a cross- sectional profile enabling it to hold the elongate strip-like display panel securely in place, and to accommodate behind said panel the necessary electronic display and communication control circuitry.
• the elongate display panel may comprise either a single strip-like display panel, eg. an LCD or other suitable display device, or may comprise a plurality of strip-like display panels mounted end-to-end in the holder to effectively form a continuous display.
• the panel, or row of panels may be covered by a single, continuous transparent cover strip.
• the holder may be adapted to replace the existing conventional form of printed label holder, or may alternatively be adapted to be secured onto the front of such an existing holder.
• an electronic labelling system for use in providing product information relating to products disposed on shelves comprising an elongate labelling device, the device including a visually continuous elongate display panel or screen which is operable to present separate data displays constituting respective labels at longitudinally spaced regions thereof.
• the labelling system also includes a central processor unit for providing product information for inclusion in the data displays constituting the labels and a bar code reader.
• the bar code reader can be used to input product information into the central processor unit and/or to provide information relating to the location of a product.
• a method of providing product information on products displayed on respective regions of a shelf comprising the steps: providing an electronic labelling device including a visually continuous elongate display panel or screen which is operable to present separate data displays constituting respective labels at longitudinally spaced regions thereof on product display shelves; and designating the locations of products and providing signals for the generation of labels on the elongate display panel or screen at regions corresponding to the locations of the products.

• an electronic labelling device includes an elongate strip-like display device 1 secured to the front edge of a horizontal display shelf 2 of a display shelving system, such as a display "gondola" in a supermarket (i.e. a ticket edge display) , or could be a free standing device that is positioned toward the front of the shelf.
• the display device 1 comprises an elongate holder 3 extruded from a suitable material, eg. plastics, and having top and bottom edge flanges 4 and 5 and end pieces 6 closing off the ends of the holder.
• a suitable material eg. plastics
• held within the holder 3 is an elongate continuous display panel 7 extending the entire length of the holder, and therefore of the shelf 2.
• This display panel 7 may comprise a single elongate continuous LCD strip panel or other suitable display device, or may comprise a number of LCD strip panels disposed end-to- end in the holder. In both cases, the display is capable of alphanumeric, and possibly also pictorial display along its entire length.
• the display panel or panels have a characteristic of being visible in an environment with overhead lights even if the plane of the display is displaced from the vertical.
• the display panels are designed to be demountable from the shelf or shelves to which they are attached for replacement or servicing.
• Fig. 3 illustrates an arrangement in which the display device is adapted to be secured to an existing conventional strip label holder 10 fixed to the front edge of the shelf 2.
• a holder 10 is formed along its upper and lower edges with elongate continuous recesses 11 which would normally hold the plastic label edges.
• the LCD or other displays can be replaced by non-display inserts to maintain the cosmetic appearance of the shelf, or manually produced labels when it is appropriate.
• Non-display and manual display inserts can, however, also be used in conjunction with other configurations of holder.
• the extrusion forming the holder 3 in this embodiment is formed on its back with projections 12 which fit securely into the recesses 11.
• the top edge 14 of the extrusion 3 lies substantially flush with the top of the holder 10, and thus presents no unsightly projections.
• the cross- sectional profile of the extrusions 3 is such as to hold the display panel 7 at generally the same upward-facing orientation as the conventional labels which would be held in the holder 10.
• This profile also includes a rear projection 15 accommodated in the space within the existing holder 10.
• This projection 15 accommodates a circuit board or boards 16 carrying the necessary IC processor chips 17 and other circuit components required for the control of the display on the LCD display panel 7, and for controlling communication with a remote central computer control (not shown) .
• Such communication may be either by way of hard wiring or by radio link.
• a data bus bar 18 may also be accommodated within the holder 3. Power will be supplied to the electronics distributed along the length of the holder from a suitable power source, eg. one or more replaceable DC power cells fitted into the holder 3, and a DC supply bus bar may also be provided in the profile 3, running the whole length of the device.
• a suitable power source eg. one or more replaceable DC power cells fitted into the holder 3
• a DC supply bus bar may also be provided in the profile 3, running the whole length of the device.
• Fig.4 illustrates a differently profiled extrusion to be used for the holder 3; in this case, the holder 3 replaces the conventional label holder, and to that end includes a flat rear wall 20 for engaging the front edge wall 21 of the shelf 2.
• the profile is adapted to mount the LCD display 7 so as to face obliquely upwardly relative to the horizontal plane of the shelf.
• the profile of the extrusion is designed so as to accommodate the necessary IC processor chips, strip circuit boards, power lines and data bus bars.
• Fig. 5 is a schematic representation of a remote system used to control display on the display panel 7 composed of a plurality of LCD display panels.
• the system includes a display control computer 30, a plurality of display controllers 32 that include the circuit board or boards 16 carrying IC processor chips 17 illustrated in Fig. 3, and a transmitter 34 for transmitting signals to the display controllers 32.
• the display control computer 30, includes display assembly software 31 that enables displays to be composed off line, and information and graphics to be drawn from a number of sources, and a 'live' transmission area 33 that controls the transmission of signals carrying information about the image for display on the display panel to the display controllers 32.
• Each display controller 32 controls the display of an area of the LCD display panel 7.
• the display control computer 30 can be an industry standard personal computer operating under a normal proprietary operating system.
• the display control computer 30 is in communication with the store's own 'back of house computer' 36 via its serial pert.
• the back of house computer 36 contains a master product file and pricing information for products in the store. As this pricing information is used to update the pricing data held at automatic scanning check-outs, by also using this information to update the information held by the LCD display panel 7, discrepancies between the information displayed on the shelves and the prices charged at the check-outs can be minimised.
• Each display controller 32 has an unique address and is designed to identify and receive signals transmitted by the transmitter 34 from the display controller 30.
• the signals identified and received by individual display controllers 32 contain information for controlling the display at areas of the LCD display panel allotted to that particular display controller 32.
• the areas of the LCD display panel 7 allotted to a particular display controller 32 can be an area or the entire length of a single strip-like LCD display panel located along the front of a shelf unit or one or more of a plurality of strip-like LCD display panels arranged end-to-end in a holder.
• the contents of the memory are then used to control the instant display on the area of the LCD display panel 7 allocated to that particular display controller 32.
• the display controller 32 is provided with a hard wired low voltage d.c. supply that provides the power source for the allocated area of the LCD display 32.
• An on-board battery power supply is also provided for instances of power failure.
• Other suitable d.c. power supplies could, however, be utilised instead.
• An operator creates a display at a desired location on the strip-like display device 7 of Figures 1 and 2, using graphics composition software held by the display control computer 30.
• the operator decides upon a shelf region for a particular product and on where in that shelf region it is desirable to provide the price information for that product.
• the operator then inputs the shelf address for the desired display region using a shelf address code which is recognised by the display controller 32 controlling the display at the desired shelf location and the product code for the product. If a number of products are to be displayed each of the product codes must be entered along with an indication of the spacing of the displays along the shelf so that the labels are displayed at the desired locations.
• the product code for each product to be displayed at a particular shelf location recognisable by the back of house computer 36, is included in the display to enable up-to-date product price information to be provided.
• the operator can draw from graphics blocks 41 held, for example, on floppy disks for insertion into the display control computer to enhance the label-type display.
• the operator can manipulate the information desired for inclusion on the display to change the size and font of display characters.
• the system may also include prompts to the operator to include graphic blocks imported from outside the system typically on a diskette.
• the system can also provide a graphic composition facility 38 to enable the operator to formulate entirely new graphics blocks.
• the process of creating can be achieved interactively on the screen with standard displays being achieved very quickly.
• a desired display format or ticket edge is stored as a complete graphics block under a reference number.
• the completed block is moved into the 'live' area 33 of the display control computer 30.
• Transmission is by secure radio transmission.
• the system will periodically refresh the shelf display by constantly transmitting the 'live' file of completed blocks in sequence.
• a new graphics block i.e. one that differs from the currently transmitted block, is loaded into the 'live' area 33 it will automatically be transmitted next in the transmission sequence.
• the display device will also incorporate elements necessary to establish communication between the processor electronics and a hand-held controller 42 used at the shelf position for the input of various information necessary to establish the alphanumeric information and/or graphics to be displayed. Commands issued by the hand-held controller 42 may also determine the exact position along the display at which the desired information is to be displayed.
• the hand-held controller may, for example, incorporate a bar-code reader 44 so that in setting up the shelf display, data defining the bar-code read from the product itself can be fed into and stored in the processor electronics of the display device as well as being transmitted to the central computer control. This facility will enable a manual cross-check to be made whenever desired between the stored bar-code and the bar-code read from the product displayed at the position on the shelf corresponding to the label constituted by a data display.
• a label can be repeated along the corresponding length of the display device, or additional information or promotional wording and/or graphics could be displayed alongside or between the labels.
