FR2765017A1 - Electronic labelling system for display of prices on supermarket shelves - Google Patents

Abstract

The electronic labelling system allows electronic labels to be fitted to the edges of shelves in a large store. The system uses a rail (1) made of insulating plastic material comprising a base and upper and lower projecting edges. The label consists of a unit (20) which fits into the rail such that it is supported between the upper and lower projecting edges. The label is held in place by two projecting pegs - one at the bottom engaging a slot in the lower edge of the rail, and one at the top engaging a similar slot in the upper edge of the rail. The upper projecting peg is mounted on a block which can move within the label so that it can project or be withdrawn. A spring (28) biased the peg to the projecting position so that it locks the label in place. A magnetic device is used to displace the block and withdraw the peg, thus allowing the label to be removed from the rail.

As a result, it is possible to move easily, which can interfere with the accuracy of the data.

the display on the gondola.

  An object of the invention is to provide an electronic tag display system in which the tags are snap-fitted at the desired location and are not likely to be moved. Another object of the invention is to propose an electronic tag display system in which the tags are capable of being extracted by a

  very simple way to implement.

  The subject of the invention is an electronic labeling system comprising a label support rail, at least one electronic display label and a label supply means, characterized in that - the support rail of the label label has a U-shaped profile with a bottom, an upper wing and a lower wing, each of the two wings having in its central zone a longitudinal groove; and the electronic tag comprises at its lower part a longitudinal rib intended to be inserted in the groove of the lower wing of the rail, and at its upper part at least one pin intended for

  snap into the groove of the top wing of the rail.

  According to other features: - the longitudinal groove e of the upper flange of the rail has at regular intervals blind holes for receiving the pin to immobilize the label in the locking position; - The longitudinal groove of the upper flange of the rail has a longitudinal sawtooth profile, the space between two teeth being capable of receiving the pin to immobilize the tag; - The electronic display label comprises at least one housing in which is disposed a ferromagnetic core carrying the pin and subjected to the action of a spring; the ferromagnetic core carries at the base of the pion a shock absorber; a means for extracting the label is provided, comprising a magnetic circuit capable of attracting the ferromagnetic core by compressing the spring in order to ensure the removal of the pin and the release of the tag; after the release of the label, the extraction means attracts the label and ensures its extraction from the rail, and the removal of the extraction means causes the withdrawal of the label; - The extraction means is constituted by a housing containing the magnetic circuit and having at least one support arm on the rail; the housing has two arms capable of being placed on either side of the rail, the magnetic circuit then being automatically in the correct position to attract the ferromagnetic core and to ensure the removal of the

  pawn and the release of the label.

  Other features emerge from the

  following description made with reference to the drawings

  in which: - Figure 1 is a schematic cross-sectional view of an embodiment of an insulating rail for electronic labeling system according to the invention; FIG. 2 is a schematic cross-sectional view of an embodiment of an electronic display tag adaptable to the rail of FIG. 1; FIG. 3 is a diagrammatic cross-sectional view of the rail of FIG. 1 provided with the label of FIG. 2, during the presentation of the extraction means;

of the label.

  In Figure 1, there is shown a rail 1 of insulating plastic material. This rail 1 has a U-shaped profile with an airfoil. It is also suitable for use in the production of gasoline. It is also suitable for use in the United States, and is also suitable for use in air handling. * uew aqe suep aquasqad ainajju eq ulsef6ew ilaluao inoqeutpao, the oo-ua-ua ua awaw-rn ['nossoodolaw a, p olquoo ai snos oeÄ [aldwaxa aeid' sapinbt [xrln3sljo e; qre4; olep ueID9 a WIOA assIel l auaJedsueaA qsa zz 4UUAe aOe-eq z ganuaidns aDej and the úZ ainaagjuT oe3 PL [ZZ queAe; gej and 'lg oaxite aoDe el eldos [aaÀn6! fj and ans sajq [stA s yo-j aa-enb salt What is the key to success? - What is the key to success? - What is the key to success? - What is the key to success? - What is the best way to do this? , -ae * anbTioua, p uaAow a aed qued [eDTqaA oz ueId al suep adnoo ua agluasgada- qsa oz anbiruoaoDo [9 aBeqoTjjfe, paaonbTqg, ['z ainfirj eL years -Aoddns uos ans Ii a np uoTqextj ap suaaow sal aa6ol arnod ajduiaxa aed alqesTIT4n '91 WEDNESDAYS WELCOME TO THE LAUNCH OF THE ALLEGHTS OF THE QUEBEC STATE OF THE WORLD. what do you say?

  This approach is frontal with respect to the rail and the label. The extraction means 43 of the label essentially comprises a plastic housing 44 and a magnetic circuit consisting of a magnet 45 and a ferromagnetic armature 46. The housing 44 is in the form of a rectangular parallelepiped provided with two arms 47 and 48 flanking the rail 1 and may bear on the support 49 of the rail 1. When the arms 47 and 48 are abutting on the support of the rail 1, and the housing 44 is in front of the label , the magnetic circuit has an air gap substantially opposite the bottom of the ferromagnetic core 29. The core 29 is then attracted downwards, and it moves by compressing the spring 28, so that the pin 30, which follows the displacement of the core 29, out of the blind hole 33 in which it was in the locking position, and the groove 12, thus releasing the label 20 which is applied to the housing 44 and follows the removal movement of the housing 44. The label 20 is then se manually trimmed housing 44, and the core 29 is then pushed by the spring 28, the pin 30 taking up its projecting position outside the casing 25 of

the label 20.

  The housing 44 may have only one arm, 47 or 48, and in this case it is put in the correct position by simultaneous support on the support 49 of the rail 1 and on the rail 1 itself, for example by lateral support against a wing,

3 or 4 respectively, of the rail 1.

  The provision of at least one arm 47, 48 on the housing 44 ensures the automatic setting in the correct position of the magnetic circuit 45-46 relative to the magnetic core 29 for unlocking the label. Then, the core 29 is attracted by the magnetic circuit 45-46 and it drives the label against the housing 44 which plays the role

  of a label gripping member.

  The invention has been described in the case of an embodiment which is not limiting. In particular, the power supply means of the power tag as information is not described and can be a wired link, a radio link or a link

capacitive or inductive.

  Furthermore, the longitudinal groove 12 of the upper flange 3 of the rail 1. may be provided with through holes, or its longitudinal profile may be sawtooth, the space between two teeth being susceptible

  to receive the pawn to immobilize the label.
