Definitions

  • the invention relates to a machine for sorting objects, for example glass, plastic or other similar material.
  • this type of machine comprises at least one sensor capable of recognizing said objects to be sorted, said sensor delivering, during the identification phase of said object, object start and end signals, when this object passes in front of the sensor.
  • the present invention therefore relates to an object sorting machine and more specifically relates to ways to properly scroll through objects to sort in a restricted area in front of said sensor.
  • the purpose of the system is to carry out the sorting of objects and for example here the sorting of plastic bottles appearing in the normal appearance of bottles but also in the form of clusters, or shredded bottles of conformation imprecise, heterogeneous in color and nature.
  • the sorting criterion depends on the sensor used chosen according to the properties of the objects to be identified (nature, color, conformation, chemical composition, physical properties).
  • Patent WO 92 / 07.232 describes a rectilinear mat for separating objects.
  • US Patent 3,900,107 describes a simple tank containing at its bottom a substantially horizontal disc requiring the use of various means to elevate the objects to be sorted from the disc to a separation mat objects.
  • WO 92 / 03.551 also describes a bottom tank in the shape of a disc relatively little tilted.
  • an object separation device consists of 5 sub-assemblies functional (reference numbers refer to figure 1 non-limiting of the invention.) which is described here for better understanding of the invention, the invention itself being only the means (centrifugal bowl) which allows the discharge of objects and send them one by one to the sensor.
  • This device includes:
  • the hopper is filled by means of handling (example a bucket loader).
  • an extraction conveyor regulates the flow of material sorting.
  • the screen is intended to evacuate the fragments as well as reduced-size objects not acceptable to the sorter.
  • At least one elevator (for example belt) (4)
  • At least one centrifugal bowl aligner separator (see Figure 2)
  • the cone is inscribed in the tank; his diameter is substantially equal to that of the tank at the operating clearance near.
  • the cone In its rotational movement the cone drives objects around it. Arrived at the "high" point of cone, the generator of it is at the level of the horizontal peripheral track. Objects are plated against the shore by the action of centrifugal force and reach a first track (3). The width of the track is such that only one object can be there. Each object is thus isolated on its track.
  • track sorting or firing track
  • At least one sorting track (8) substantially horizontal and tangent to said first track, therefore concentric with the tank (2) from which it is separated by said crown. (figure 2).
  • the sorting track is independently driven. Its rotation speed, greater than or equal to that of the tank increases the interval between Items.
  • the device according to the invention can be supplemented, for example, as follows:
  • the trajectory described by the sorting track is preferably divided into angular sectors.
  • a sector generally, the first sector, located immediately after the break in the shore, is reserved for the identification of the object.
  • the mesh structure of the mat allows positioning of the sensor (7) on either side of the object to be identified. Most of the other sectors are used to collect identified and separate objects. The number of the following sectors depends on the selectivity that one wishes to bring to the objects.
  • Each sector corresponds to a type of object to be sorted.
  • a sector for example the last, is a scrap zone for badly identified or unidentified objects or can be used for any other particular recovery of objects not selected in the other sectors.
  • the position of the sensor (7) on Figure 2 is not limiting.
  • An ejection system (10) (for example by forced air) is located under the carpet sorting at the level of each sector. Objects once ejected are guided to a specific silo.
  • the purity level of the batches constituted is generally greater than 98%.
  • the rates of sorted bottles can reach 18,000 bottles per hour.
  • the lots sorted by material are sent to different centers specialized recycling.
  • the sorting machine incorporates the sensor which allows to recognize the different materials.
  • the sensor used is for example, a near spectrometer infrared (NIR) with factorial filters from BUHLER.
  • NIR near spectrometer infrared
  • Bottles or other objects to be identified are illuminated with a source of light (for example with halogen lamps) and measured without contact physical with the sensor.
  • a source of light for example with halogen lamps
  • the ejection of bottles or other objects is done by air push compressed.
  • the blow guns used deliver a precise directional jet and measurable.
  • the entire installation is generally controlled by a PLC which mainly ensures the regulation of the bottle flow, the dialogue with the sensor as well as the control of the ejectors.
  • the sorter assigns the identified object to the specific silo.
  • the sorting track is equipped an angular position sensor.
  • the relative angular position of each receiving silo in relation to the reference position of the sensor identification is measured beforehand and then configured at the automaton.
  • the sensor delivers the signals to the PLC. start and end of object. These signals are synchronized by the PLC to information delivered by the angular position sensor in order to measure the length of the object. The precision of this synchronization allows also to delimit areas of the object to be ignored or treated particularly (bottle cap, label, ink, barcode, painting etc ). Knowing this length makes it possible to determine the optimum point of impact of the shot.
  • This device also comprises at least a second track called sorting track (8) concentric with the tank (2) and located at the periphery of said first previous track, substantially horizontal and tangent to said first track, of which it is separated by said crown, this sorting track being driven independently.
  • the device according to the invention applies to the separation of objects of size, shapes, colors, and variable masses.
  • the objects to be sorted are by example of glass or plastic bottles.
  • the device is particularly suitable for sorting bottles broken, shredded or crushed plastics (provided they are not not welded or glued, entangled together by procedures overwriting).
  • the device is also suitable for sorting packaging plastics of all kinds, e.g. laundry packaging, products cleaning products, food products (oil containers), products for cars, gardening products, fertilizers or all types of packaging similar. We can sort mixtures of all the objects mentioned above.
