Description:
TECHNICAL FIELD  
       [0001]     The present invention concerns a device for automatic dispensing of single disposable tickets and particularly concerns a device for customizing and dispensing contactless smart tickets.  
       BACKGROUND  
       [0002]     Machines for dispensing disposable tickets, such as paper tickets, usually store the tickets in the form of rolls or as fanfold paper. According to these two methods of storage, the tickets are stuck together in the form of strips. This system has the advantage of being able to dispense continuously but occupies a lot of space. A guillotine cutter cuts the ticket on request just before it is dispensed. Unfortunately, this type of dispensing machine is not entirely suitable for disposable contactless smart tickets called “contactless tickets”. Actually, the production efficiency of contactless tickets is less than that of ordinary disposable tickets considering their technology that requires more precision. The method of storing tickets in continuous rolls does not allow for the removal of defective tickets during production and thus all defective tickets, about 5% of the lot, are retained. With every ticket being checked prior to it being issued to the client and every defective ticket being directed to a waste storage location, the large proportion of defective tickets increases the mean delivery time of a ticket to the client. Furthermore, the storage of tickets in continuous rolls and the large proportion of defective tickets requires a significant volume within the dispensing machine.  
         [0003]     In order to reduce the number of defective tickets, one solution consists in discarding them before they are inserted into the dispensing machine. This solution therefore requires the storage of tickets in the form of stacks in the dispenser and it also helps overcome space problems. This type of dispenser exists for dispensing plastic cards or “polyester” tickets whose physical characteristics, such as the elasticity, are similar to that of plastic. The polyester cards or tickets are stored one by one in stacks and are unstacked as they are dispensed. Certain systems operate by pushing the card with a blade that presses on the thickness of the card to unstack the cards. Other systems bend and pinch the card by using the stiff and elastic properties of the card. Apart from the fact that these dispensing systems where the cards are stored in stacks save a significant amount of space compared with a roller dispensing system, they also allow tickets to be reused, i.e. the re-dispensing of tickets already distributed once, which is impossible when the tickets are stored in rolls or as fanfold paper.  
         [0004]     Unfortunately, these methods for unstacking single tickets are not suitable for disposable contactless smart paper tickets. Actually, this type of ticket has very specific physical characteristics compared with ordinary disposable tickets. Its surface is not flat but is raised where the chip is located. Furthermore, unlike the plastic card, the ticket is not elastic enough to fully recover its initial configuration when the pressure exerted on the ticket is released. Finally, such a ticket may be crinkled along its axes. There are therefore no dispensing devices suitable for contactless smart tickets and thus, in addition, there do not exist any automatic dispensing devices for contactless smart tickets. As a result, dispensing as well as customizing contactless smart tickets currently requires manual intervention.  
       SUMMARY OF THE INVENTION  
       [0005]     This is why the object of the invention is to create a compact device for automatic dispensing of smart contactless paper tickets.  
         [0006]     Another object of the invention is to create a device for dispensing single contactless smart paper tickets capable of programming and marking every ticket in order to customize it according to request.  
         [0007]     The object of the invention is thus a device for customizing and automatically dispensing single smart contactless tickets provided with means to check the reliability of tickets and means to customize the tickets and including a storage location for tickets in the form of a vertical stack. According to the main characteristic of the invention, the dispensing device includes a suction cup provided with means to control its vacuum and integral with a movable arm moving along a vertical path, the suction cup enabling the unstacking and removal of a ticket from the storage location and carrying it until it rests on a drive system, and an external antenna adapted to check the reliability of the ticket initially at the time of unstacking.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0016]     According to the diagrammatic view of  FIG. 1 , the dispensing machine consists of at least one removable cassette  10  containing about 500 contactless smart tickets  12  stacked and compressed vertically with a weight  14 . The contactless smart tickets include an antenna and a unit or a chip connected to the antenna. The stack of tickets rests on the two edges or bosses  16  of the cassette  10 . Between the bosses  16 , a flapper opening allows the tickets to pass through. The dispensing machine includes a carriage consisting of a movable arm  31  moving along a vertical path on which a suction cup  20  is fixed. A table, not shown in the figure, on which an antenna is engraved, has an opening at its center adapted for the suction cup  20  to pass through. Two parallel smooth belts  40  supported and driven each by two pulleys  42 , which are themselves driven by a motor, are placed parallel to the edges of the table so as to enclose the table. The antenna  24  is placed at the periphery of the table so as to enclose the opening located at its center. According to a variant, the antenna is fixed to the movable arm  31  and the opening in the table allows the suction cup  20  and the antenna  24  to pass through. The antenna  24  is connected to at least one microprocessor not shown in the figures and equipped with a memory. The two belts constitute driving means for the tickets and are placed under the stack of tickets parallel to the plane of the tickets. Two rollers  44  press on the recesses of the parallel belts  40  just next to the pulleys  42 . The arm  31  is set in motion by a lifting/lowering mechanism made up mainly of a plate  32 , a column  33  attached to the plate, a motor assembly  36 , a crankshaft  35  and a connecting rod  34 . The arm  31  is guided along its vertical path by the column  33  and set in motion by the motor, crankshaft and connecting rod assembly. The suction cup  20  moves in the direction perpendicular to the plane of the tickets so that its grasping plane is in the plane of the tickets. The suction cup  20  preferably moves along an axis perpendicular to the ticket passing through the center of the ticket or passing through the ticket&#39;s center of gravity. The suction cup  20  is of the release suction cup type and has means to control its vacuum such as, preferably, a valve  26  kept closed by a spring  28 .  
         [0017]     The stages of operation of the dispensing machine are diagrammatically shown in  FIGS. 2 through 5 . Tickets are unstacked one by one on request from the client who formulates his/her request via a communicating interface with the dispensing machine&#39;s microprocessor. According to  FIG. 2 , the suction cup  20  and the arm  31  are set in motion and when the suction cup comes in contact with the first ticket  13 , it compresses itself while letting the air escape from the side of the suction cup as it cannot be removed by the internal valve  26  that is closed. While the crankshaft  35  passes the top dead center and the motor  36  continues to rotate, the suction cup tends to decompress itself and thus creates a vacuum, which drags the ticket  13  downwards. The ticket  13  first held by the bosses  16  of the cassette loses its shape, as shown in  FIG. 3  and ends up coming out of the cassette. The suction cup  20  on which the ticket  13  is held and the arm continue their downward movement until the spring  28  is compressed on the stop  38  of the plate  32  as shown in  FIG. 4 . When the spring  28  is compressed, the valve is driven upwards and lets the air into the suction cup as it opens up thereby releasing the vacuum from it which in turn releases the ticket.  
         [0018]     According to  FIG. 5 , which represents a diagrammatic section according to a plane perpendicular to the sectional planes of FIGS.  1  to  4 , the belts  40  are parallel and located around the table  30  so that they are supported. The table  30  consists of a groove  39  in which the ticket rests when it is driven by the suction cup  20 . The groove  39  helps cope with unevenness of tickets and ensure they will always rest on the belts  40 . Once released from the suction cup, the ticket  13  then rests on the two parallel belts  40 . The operation that consists in taking the ticket  12  from the stack and bringing it up to the driving device constitutes unstacking of the ticket.  
         [0019]     With reference to  FIG. 6 , the ticket is then subjected to an initial check by the antenna  24 , located around the suction cup  20  in order to determine whether the ticket is able to communicate with an external antenna and therefore determine the reliability of the ticket. The checking operation is possible thanks to a communication protocol programmed in the microprocessor, which manages the communication and data exchange between the disposable contactless smart ticket and the antenna. If the ticket communicates, the microprocessor transmits a message to the motor driving the pulleys, which then rotate in a direction that makes the belts  40  rotate according to a movement that feeds the ticket into a printer  50 . The free rollers  44  press on the belts  40  to lay the ticket flat and ensure that it is fed. The printer in turn drives the ticket and marks it with graphical information in order to customize or number it. The speed differential between the belts and the printer, if any, is compensated by the sliding of the ticket on the smooth belts. The ticket is printed by a standard thermal printer.  
         [0020]     Once the ticket is printed, it is put back by the printer on the belts  40 . The ticket is then re-checked by the antenna, then electronically programmed by the antenna that receives its instructions from the microprocessor to complete the customization. For this, digital data is transmitted by the antenna  24  and the ticket&#39;s antenna to the chip of the ticket by means of the communication protocol. The digital data transmitted is adapted to the type of use of the ticket and possibly the user&#39;s request via the communicating interface connected to the microprocessor. For example, there may be a certain quantity of time units for a parking ticket that determine its validity period. The checking and programming times are very short, in the order of a few tenths of a second. Once the ticket is programmed, it is validated so that it may be distributed to the client. The antenna then transmits to the microprocessor a motor control message for driving the pulleys, which then rotate in a direction that makes the belts  40  rotate with a movement that takes the ticket towards the dispensing outlet located on the side opposite the printer as shown in  FIG. 7 .  
         [0021]     During checks that are carried out at the time of unstacking and at the time of programming, if a communication error is detected, the antenna transmits the information to the microprocessor so that the printer ejects the ticket to a tray located downstream of the printer where all rejected tickets are automatically stored. This arrangement helps do away with a switch system and improves the compactness of the product.  
         [0022]     As shown in FIGS.  1  to  7 , the plate  32  is guided during travel by two pins  37  with the help of a mechanism not shown in the figure for an embodiment with two ticket cassettes. This non limiting characteristic of the invention enables the carriage to be moved horizontally and positioned in front of another cassette when the first cassette is empty or otherwise unavailable. However, according to a variant of the embodiment of the invention, the ticket-dispensing machine is equipped with two cassettes and two identical carriages as described previously, each carriage being stationary and designed to extract the tickets from one of the two cassettes. Preferably but not necessarily, the cassettes of this invention are secure and reusable. They are refilled in a secure workshop. At the time of their closure they are set to allow only one insertion into the ticket-dispensing machine. A lead seal, or any other equivalent method, ensures that the cassette is not opened during its duty cycle outside the secure workshop. The cassettes will be locked when they are being transported, making it difficult to extract the tickets without visible damage. When it is inserted into the ticket-dispensing machine, the cassette will be unlocked and its flapper will open enabling the tickets to be dispensed. Then, when the cassette is removed from the dispensing machine, its flapper will be locked again but will be disarmed, preventing it from being reopened and therefore reinserted into the ticket dispensing machine. In this way, it is not possible to reinsert a cassette that is empty, half-full or removed for unavailability.  
         [0023]     According to an embodiment with two cassettes, the ticket dispensing machine uses all tickets from the first cassette and when the latter is empty the dispensing automatically switches over to the second cassette. A light indication informs the maintenance personnel of the condition of the cassettes: in operation, empty or faulty.  
         [0024]     The ticket-dispensing machine according to the invention has the advantage of being able to adapt themselves to various client interface systems commercially available. Furthermore, the communication protocol programmed in the microprocessor is capable of communicating through a computer, a network, a modem or even in a standalone manner.  
         [0025]     The ticket-dispensing machine according to the invention has the advantage of being small in size, in the order of 400 mm×200 mm×150 mm. Thus, it can easily be integrated with ordinary disposable ticket dispensing machines without major modifications to these or can even be placed on a desk.  
         [0026]     In addition, the invention can be adapted to tickets of different shapes and materials, with chips of various sizes without having to be modified. The invention may be applied particularly to “tag” type tickets and/or “RFID” (Radio Frequency Identification) tickets.  
         [0027]     Thanks to the single dispensing mode of the invention, tickets that are already used may be reinserted into the cassette so that they can be reprogrammed and re-dispensed even if they are crumpled or have folds.
