Definitions

  • the present patent application relates to a new doser to be used in color-based, grain sorting electronic machines, for the most varied granular products.
  • the doser will be manufactured by electromechanical industries and used by the agro industrial sector and other grain sectors.
  • color-based, grain sorting electronic machines mainly granular products such as rice, coffee, lentils, maize, wheat, oat, soybean and a variable range of several particle and granular products, are traditionally known for consisting of a base, five operational phases, that is, feeding hopper, electromagnetic vibrator with vibratory chute (doser), conveyor chute, electronic optical reading sensors and ejecting valve.
  • feeding hopper electromagnetic vibrator with vibratory chute (doser)
  • doser electromagnetic vibrator with vibratory chute
  • conveyor chute electronic optical reading sensors and ejecting valve.
  • the hopper is used to store the grains that will be used in the machine for the beginning of the electronic selection process of grains, which are conveyed by electromagnetic vibrators with vibratory chutes, subsequently conveyed by an inclined chute, thus causing a free fall of the grains that will be inspected when they pass through a specific internal point; such point is equidistant between two electronic optical systems, a reading sensor and a complex electronic system where the colors of the grains will be analyzed.
  • the machine After the grains are analyzed, the machine will automatically decide which kind of grains it will reject. This adjustment is made by the machine operator who uses electro-pneumatic ejecting valves so that the machine can eject from the grain flow track those grains considered defective due to their color, a factor determined by the previous machine adjustment.
  • the color-based, grain sorting electronic machines that use conveyor belts have more limited features, because when the grains pass through the electronic optical reading sensor for inspection it is not possible to raise their speed for production increase, because if the belt speed is changed, the grains to be inspected move out of the track of the sensor reading center, thus jeopardizing the entire analysis system of the machine.
  • This kind of machines is also limited for other applications, because they can only increase their production by means of electromagnetic vibrators with vibratory chutes, whereas the speed of the conveyor belts must be steady and can not have variations.
  • the conveyor chutes are fastened in such an angle that they take advantage of the gravity force to accelerate and increase the speed of the grains passing through the reading sensor of the machine. Nevertheless, until today, the machine production doses are stili being made by means of electromagnetic vibrators with vibratory chutes.
  • the electromagnetic vibrator with vibratory chutes has a limitation as to the operation and production dosing of the machine.
  • a pulsed electronic circuit that feeds the vibrator coil
  • a pulsed magnetic field that moves the vibratory chute, horizontally, forward and backward is also created.
  • the machine production dosing is made through the movement of the vibratory chutes.
  • the pulse frequency of the vibratory chute the machine dose increases or decreases, that is, determined by the operator, the production increases or decreases according to the defect percentage, the colors contained in the product or by the machine limitation.
  • Another inventive point is the motorized feeding belt used as a doser and feeder of the machine production flow, instead of the current pulsing electro-magnetic vibrators.
  • Figure 1 general side view of the doser, with enlarged details for a better visualization, and arrows indicating the track of the grains from the entrance through the optical sensor selection at the machine's exit.
  • Figure 2 general front view of the doser, with enlarged details for a better visualization of the alignment and the track of the grains on the chute, represented by solid lines and indicative arrows.
  • the model hereof is characterized by a dosing machine (1), made of a hopper (2) to store the grains to be selected, a motor (3) that drives the feeding belt (4), which in turn directs and leads the grains toward the feeder & conveyor chute (5), which leads the grains to the exit (6); such machine is provided with a set of electronic reading optical sensors (8), a reading camera (10) that selects the grains by their color, activating the ejecting air valve (7) with discharge nozzle (9), to select and separate the grains, as previous configuration.
  • the conveyor chute (5) receives and conveys the grains in an aligned way up to their release at the exit (6) so that the sets of electronic reading optical sensors (8) can accomplish the reading procedures.
  • the motorized feeding belt (4) is used to dose and feed the machine production flow (1) and it transfers the grains from the hopper (2) to a conveyor chute (5) that receives the granular products, that is, the grains (detail of figure 2 ), aligning and conveying them, up to their release at the exit (6) so that the sets of electronic reading optical sensors (8) of the selecting machine (1) can accomplish the reading procedures.
  • the machine (1) production is controlled by increasing or decreasing the motorized feeding belt (4) speed, and not by increasing the pulses of the electro-magnetic vibrators (not illustrated).
  • Dosing and feeding the machine (1) by a feeding belt (4) is carried out linearly and does not cause aggregations of grains on the conveyor chutes (5); such aggregations can interfere and directly damage the electronic optical sensors (8) reading of the reading sensor (10) of the machine (1).
