Definitions

  • the invention relates to an apparatus for withdrawal of rigid or non-rigid container of products liquids or solids whose identification is ensured by the recognition of a specific marking of this container recorded.
  • French Patent No. 2,580,418 mentions the use a device for detecting the presence of a marking on a goblet to identify it and restore a value. This patent, which was also abandoned, does not offer any embodiment of this detection device.
  • WO 93/03461 describes a control device of identification signs for cups. This picks up and uses a light barrier to evaluate a light thoughtful characteristic of identification signs.
  • the reading device placed too close to the cup to be identified provides insufficient results reliable.
  • the light barrier thus arranged is very easily soiled.
  • French Patent No. 2,645,305 describes a system of recognition by optoelectronic means.
  • French Patent No. 2,631,477 describes a system of recognition of the cup by depression.
  • US Patent 4,316,533 describes a device for recovery of empty containers leading to delivery of a counter value.
  • the marked containers are identified by reading this mark using a program ultraviolet which, when it meets the mark, gives birth of a fluorescent emission.
  • US Patent 4,248,334 describes a recycling device in which a reader identifies the reflection of a ray laser by a marking made on the container.
  • US Patent 4,248,389 describes a sorting device for various types of container. Identifying these types of container is provided by an optical reader (whose technical characteristics are not developed in this document).
  • the inventions already made have a limited reliability as their systems identifying the type or origin of the container take into account neither the stain or deterioration partial marking or reading cells, nor the reading on the overlay of the container marking.
  • An object of the present invention is an apparatus for withdrawal of a container whose reliability identification is significantly increased by redundancy reading the marking.
  • Another object of the present invention is an apparatus of disconnection of a container capable of ensuring a reading fine enough to read with great precision a relatively complex marking and therefore hardly falsifiable.
  • Another object of the present invention is an apparatus of disconnection of a container presenting a device for security allowing the delivery of the deposit only after the container has fallen into a specific receptacle, thus avoiding multiple restitution of instructions for the same container.
  • the invention relates to a device for deconsigning a whether or not rigidly containing liquid or solid products.
  • the invention can be used for any type of object likely to bear a mark which can be read by the device described below.
  • Graphic or screen printing is carried out on the container with a conductive or non-conductive food ink by a known method.
  • Improvement of the device for identifying the marking according to the invention consists of redundancy of reading this marking.
  • the deconsignation device of at least two reading can, for example, be implemented by providing the deconsignation device of at least two reading.
  • the plurality of these sites makes it possible to avoid reading errors, and therefore non-restitution of instructions for normally returnable products, caused by soiling, soiling, deterioration partial, etc. identification marking or reading device.
  • the signals corresponding to the reading the marking are then processed by a function logical, for example "or" inclusive.
  • the recognition of marking by a single reading site therefore involves the return of the deposit.
  • the second site, and possibly the following ones, therefore constitute sort of the compliance verification sites the marking.
  • the container to be identified which can carry soiling, soiling, etc. is sufficiently far away elements ensuring reading to avoid any contamination or deterioration of these.
  • the improvement of the reading device marking according to the invention also consists of the use of at least two cells emitting light beams and two photoelectric sensors, arranged in pairs, by reconnaissance site.
  • the number of these cell / sensor pairs varies according to the complexity of the marking to be identified. Complex marking, and therefore difficult to falsify could be recognized by the combination of multiple pairs cell / sensor.
  • these cells When a container is placed in position of identification, these cells emit beams bright such as white light, laser beams, ultraviolet, infrared, etc. whose reflection varies in depending on the area encountered of said container. Indeed, a marked area does not reflect these beams as a unmarked area.
  • the reflected beams are then received by photoelectric sensors that analyze digitally these signals, achieve a combination which is then compared to a reference combination stored at using a card that can contain a microprocessor by a known process.
  • the instruction to return the deposit is then given if the marking has been recognized.
  • Figure 1 shows a built-in part (4) of the general device of the disconnection device according to the invention. It particularly shows the introduction of the container (1) in the chute (9) shown in the figure 3. Introductory (2) and recovery (3) lamps indicate the evolution of the identification process of the containing (1) preceding the issue or not in the coin receptacle (7) for coins corresponding to the value of the deposit.
  • Figure 2 shows the progress of the container and parts in the voucher according to the invention.
  • the container (1) is introduced into the introduction chute, slides between two jaws, located in the reading airlock, which immobilize it so precise with respect to a plurality of pairs cell / sensor arranged in two sites (only the site (10A) is shown) to ensure reliable identification of the marking.
  • the combination of cell / sensor pairs (11a), (11b) and (11c) identifies the presence of a type of container other than that intended for the device by detecting the time path of the container.
  • the cell / sensor pairs (11b) and (11c) are used to check the path, represented by the arrow (8), in the common sense of the container.
  • the end of passage signal container (1) is received by the corresponding sensor, usually the closest to the container receptacle used, the deposit is returned.
  • the parts stored in the storage rotor (5) are released in the lowering of the parts (6) and fall into the receptacle (7).
  • Figures 4, 5 and 6 particularly represent a example of positioning of the recognition device (10) marking of the container (1), of the recognition of conformity of the type of container formed by the pairs (11a), (11b) and (11c) and of the control of the correct progress of the container (11b) and (11c).
  • the cell / sensor pairs (10) of the device identification marking are arranged in two sites (10A) and (10B). Open windows in the airlock wall read (12) allow them to send to the container (1) and to receive light beams from it.
  • Each cell / sensor pair of each reading site (10A) or (10B) is arranged so that the transmitting cell is placed on the same site as the sensor assigned to it associated, thus being able to capture the reflected beam.
  • the emitting cells are diametrically opposed to the sensors associated with them.
  • Figure 6 shows, in addition, the device allowing the immobilization of the container (1) by jaws (15).
  • a spring (14) keeps them at rest for retain the container (1) and allows them to be separated by actuation of a cam (13) driven by a motor according to a known method for releasing said container.
  • the invention will be better understood by reading a preferred embodiment example applied to a device for the withdrawal of a container (1), in particular from cups issued by vending machines for drinks hot or cold, by identifying a marking determined made on this container.
  • the determined design allowing reliable identification of the cup is performed by graphic or serigraphic marking of the container with a conductive or non-conductive food ink according to a process known.
  • the cup (1) introduced into the device is first placed in a predetermined position in front of the reading of the marking. To do this, it is introduced in the device by the chute (9) in the vertical direction, its opening up. Going down into the device there passes between two jaws (15) which constitute a means known immobilization of such containers.
  • the cup is thus always immobilized at the same place in the same position in the reading airlock (12).
  • a reading device comprising at least two sites (10A) and (10B) for reading each consisting of a plurality of cell / sensor pairs (10) as described previously. These pairs are fixedly arranged at specific points around the cup and at a distance of this between 3 and 7 mm. These sites allowing the read redundancy are mobile or fixed and usually arranged so as to touch the wall of the airlock.
  • the marking of the cup (1) constituting a series of clear codes and dark codes and each emitting cell a light beam directed on a determined area of the cup, the reflection of this beam is different depending whether it meets a dark area or a light area (area marked or unmarked area) of the cup. Reading this reflection is done remotely by the photoelectric sensor associated with each cell. For example, a light area returns a logic level zero, a dark area returns a logic level 1.
  • the information thus received and interpreted digitally by sensors provide a combination.
  • this combination is then compared to a reference combination previously stored for a marking determined according to a known process.
  • a variant of this preferred embodiment has a container type control system introduced into the device.
  • This system consists of the three cell / sensor pairs (11a), (11b) and (11c) capable of detecting the time path of the container.
  • a non-conforming container is not immobilized by jaws (15) and falls directly into the receptacle of used containers. Its non-compliance is signaled by the rapidity of this fall, the deposit is not returned.
  • a container of the type provided by the disallowed is immobilized by the jaws. His marking must then be identified so that the deposit is returned.
  • a preferred embodiment of a according to the invention has a device for reading of marking of the container made up of two sites of diametrically opposed reading (10A) and (10B) in the airlock reading (12), each comprising three cell / sensor pairs (10) these being located at a distance of between 3 and 7 mm from the container put in place for identification.
  • An alternative embodiment of the invention has infrared emitting cells and their sensors associated photoelectric.
  • Another variant embodiment of the invention also has a safety device which does not allow issuing the deposit for the returnable container (1) and identified that after falling into a receptacle of recovery.
  • this safety device prevents the return of a deposit if the container travels in the opposite direction to that leading to this receptacle.
  • This system consists of at least two pairs light beam emitting cell / sensor photoelectric (11b) and (11c), the former being able also, depending on its positioning in relation to the container immobilized, serve as presence detection device of a container.
  • pairs are arranged at different levels of the path followed by the container. This arrangement allows check the direction of passage of the cup.
  • Each cell is diametrically opposite the sensor associated with it and is flush with the wall of the guide duct the container to the recovery receptacle.
  • the cell constantly emits a light beam received by the sensor.
  • the signal for the passage of the cup is given by the interruption of the reception of this beam by this sensor.
  • the return of the deposit is only granted after the end of the beam reception interruption illuminated by the sensor (11c) closest to the receptacle recovery.
  • the efficiency of the safety device is increased by its ability to detect the path of the container recovery receptacle to the introduction chute (9).
