Definitions

  • the present invention relates to a method and an installation for encouraging the return of trolleys in a supermarket.
  • the method according to the invention in addition to its effectiveness against fraud, allows the user who has inadvertently engaged his trolley in the receiving area, to remove it without difficulty, which could not be obtained with known installations, in which the beginning of the engagement of the trolley in the reception area resulted in its blocking and the impossibility of its removal.
  • the first identification being carried out
  • the first and the second identifications are carried out by optical detection of determined geometrical characteristics of the carriage being restored.
  • the identification of the carriage is carried out by a measurement carried out on the latter, during the relative movement of the carriage and of an appropriate identification assembly.
  • the first and second identifications are carried out by counting a number of vertical or substantially vertical bars of the carriage.
  • the counting of the bars is carried out only on one side of the carriage, which avoids identification errors in the case where the carriage is incorrectly inserted.
  • the invention also relates to an installation for implementing the above process for the return of carts or the like in a closed reception area, with access controlled by a retractable and possibly lockable barrier.
  • This installation comprises at least a first trolley recognition equipment, located upstream of a device access control or barrier, a second equipment for recognizing the trolley, located between the first i-dantification equipment and the access control device, possibly a lock for immobilizing the access control device in position d 'prohibition of access (lock whose opening is controlled by the first recognition equipment), a device control system, in particular of the barrier or gate allowing the latter to be retracted only downstream and its recall in the initial position prohibiting access, a member sensitive to the closed position of the barrier and a set of controls for the correct sequential flow of operations controlling the distributor of the means of proof.
  • the first and second recognition equipment respectively comprise an infrared ray device whose transmitter and receiver are arranged on either side of the access 2 to the reception area , so that, in the case of an openwork carriage, this carriage is recognized by ur, counting of the bars constituting one of the lateral flanks of the chaciot.
  • the transmitter and the receiver of each infrared ray equipment are offset in height one relative to the other so that the emitted ray is inclined relative to the horizontal reference plane on which moves the cart to the receiving area, one of the cell elements being located higher than the top edge on one side of the cart, while the other cell element is located lower than the top edge on the side of the carriage.
  • the invention provides, to take into account only the bars of the carriage on one side thereof, that the top element of the infrared ray device is located higher than the edge of the larger carriage, while the bottom element of said device is below the edge of the minimum carriage.
  • the transmitter and the receiver of each device are mounted in an adjustable manner in height on a support. substantially vertical to allow their adaptation according to the types of carriages to be checked.
  • a pair of infrared cell devices is associated with a group for counting the signals emitted by the receiving cells, this arrangement avoiding fraud consisting for example in moving the trolley according to successive back and forth movements in front of the cells suitable for operating the opening of the door to the reception area.
  • a trolley receiving area has an access corridor to which are connected on either side of the tubular elements forming part of an enclosure limiting said area.
  • the area or airlock for access to the reception area is limited by two lateral boxes 5 and 6 parallel to each other and connected to their upper rear parts by a transverse box 7, the assembly having, in horizontal projection, the form d 'a U.
  • the boxes 5 and 6 as well as the box 7, of generally parallelepiped shape can be made in any suitable manner, in particular from folded sheet steel, or include a metal framework like that which is represented in FIG. 2 , covered with a covering hiding and protecting the internal organs.
  • the assembly is fixed to the ground by lower fixing gussets 9.
  • a bowl 11 placed at the outlet of a chute and intended to receive a ticket issued by the machine after the user has introduced his cart into the reception area.
  • the chute is attached to a ticket distributor 12 comprising conventionally a drive motor which advances step by step a roll of paper pre-glued, a tin guillo- p cutting the paper to release a ticket for each operation, the ticket then being evacuated by the chute towards the user.
  • This ticket dispenser 12 which is not shown in detail because it is well known, is fixed inside the box 6, in a place inaccessible to the user, on a plate 13 bolted to the frame and intended also to receive electronic components used for the operation of the installation and which have been referenced SC.
  • the airlock to the reception area is normally closed by two gates 14 pivotally mounted by their outer edge around vertical axes which can open, from their closed position where their internal edges are joined, only downstream, as shown by the arrows F 1 , F 2 °
  • a control mechanism contained in one of the boxes 5 or 6.
  • each gate is constituted by a bent U-shaped tube fixed on a vertical shaft 15 rotatably supported in bearings 16 1 , 16 2 mounted on supports 17 1 , 17 2 fixed to the frame of the box 6 or 5.
  • a return spring 18 At the upper end of the shaft 15 is hooked a return spring 18 whose other end 19 is in abutment against a fixed part of the frame. This spring automatically returns the gate, when it has been opened, to the closed position shown in FIG. 2.
  • a damping device which is wedged on the shaft 15 and simply constituted ( Figures 5 and 6) by a disc 21 of flexible material , such as rubber, sandwiched between a sleeve 22 fixed by a screw shown diagrammatically at 24 on the shaft 15 and an upper disc 23, the discs 23 and the sleeve 22 being secured by screws.
  • the outer edge of the rubber disc 21 is in constant abutment against an edge 25 of a small cubic block 26 of the fixed frame, so that these two elements rub against each other when the gate closes, the shaft 15 then turning in the direction of the arrow f 2 ( Figure 6).
  • the gate 14 can be kept in the closed position by means of a lock device which is shown in detail in FIG. 4.
  • a part 27 On the lower end of the shaft 15 is wedged a part 27, in the form of a sector. , pierced with holes 28.
  • This part 27 is located under a support 29a fixed to the frame 30 of the box and carrying an electromagnet 29 whose movable core 31 is slidably engaged inside a hole in the support 29a and is capable of projecting downwards by penetrating into one of the holes 28 of the part 27 secured to the shaft 15.
  • a stop 31a, located under the part 27, makes it possible to limit the stroke of the core 31.
  • Boxes 5 and 6 are also provided on the framework fixed switches 32 which are actuated by the gates when they pivot and which act as detectors for the presence of the gates.
  • the opposite faces 33 and 33 'of the two boxes 5 and 6 have openings, respectively 35.36, 35', 36 '( Figure 1) each closed by a plexiglass panel (methyl methacrylate), letting pass the infrared rays , thus concealing the interior of the boxes from users. Behind these panels are housed transmitters and receivers that are part of infrared ray devices.
  • Each device comprises a transmitter 37 and a receiver 38, respectively 37 1 and 38 1 (FIG. 2) behind the openings 35 and 35 ', and 37 2 and 38 2 behind the openings 36 and 36'.
  • Each transmitter and each receiver are mounted to slide on a vertical column, respectively 39, 39 ', disposed between .supports 40, 41 fixed to the fixed frame of the installation. This arrangement makes it possible to adjust the height of each transmitter and each receiver.
  • each transmitter and each receiver are also adjustable by rotation about a horizontal axis A parallel to the mean longitudinal plane of the installation. This double possibility of adjusting the position of the transmitter and receiver allows, on the one hand, an adaptation of the installation to different trolley sizes, as seen with reference to FIG. 3, and, on the other hand part, to make a determination of the nature of the carriage only on one side thereof.
  • FIG. 3 there is shown in solid lines the carriage of smaller size and in broken lines the carriage of maximum size.
  • the carriage C (FIG. 7) has sides or sides formed by vertical or substantially vertical bars B.
  • the transmitter 37 1 is placed at a higher level of the distance H l than the upper edge of the maximum gauge carriage and the receiver 38 1 is placed at a lower level of the distance from H 2 than that of the upper edge of the smaller trolley.
  • the spokes emitted by the emitter tor 37 1 to the receiver 38 1 meet only one side of a carriage C whose gauge is between the maximum gauge carriage and the minimum gauge carriage.
  • the indicator V 1 (green) is on for the entire duration of the cycle and does not go out accordingly until the ticket is issued.
  • V 2 indicator When the V 2 indicator is red, this is a sign of the installation's out-of-service condition. - When the V 3 indicator is red, this indicates the need to refill the machine with a paper roll. to tickets.
  • a fourth indicator can also be provided which, when it is red, signals that the reception area can no longer receive a new carriage.
  • the gates 14, previously locked in the closed position are unlocked by the excitation electromagnets 29 of the locks; the cores 31 are attracted and thus release the part 2 ⁇ integral with the shaft 15.
  • the unlocking of the gates is controlled by the association of the two detection systems, this is ie 37 1 , 38 1 on the one hand, and 37 2 , 38 2 on the other.
  • the gates being unlocked it suffices that the user continues to advance his carriage to push the gates downstream of the installation and thus open them.
  • the switches 32 for controlling the presence of the gates in the closed position then change state and allow the validation of the second transceiver device 37 2 , 38 2 which begins counting the vertical bars B of the carriage.
  • the number of bars counted by the second device reaches a predetermined value, recorded beforehand in the installation and corresponding to the second identification of the cart, the user just has to keep moving the cart forward so that it escapes completely to the gates and that they can return to the closed position under the effect of the return springs 18.
