Description

  This utility model relates to a novel flow rate regulator used in an electronic sorter that sorts granular materials according to the color of the granular materials for various granular products. The flow regulator is manufactured by the electronics industry and is used in agriculture-related industries and other granular industries.

  Traditionally, an electronic sorter that sorts granular objects, especially grains such as rice, coffee, green peas, lentils, corn, wheat, oats, soybeans, and other granular products by color, basically has five stages: the feed hopper. It is known to be constituted by an electromagnetic vibrator (flow rate controller) with a vibration chute, a conveyance chute, an optical reading electronic camera, and an ejector valve.

  The hopper is used to store the granules to be put into the machine for the start of the electronic sorting process of the granules, which are supplied by an electromagnetic vibrator with a vibrating chute and then via an inclined conveying chute Fall. When passing a fixed equidistant position between the two optical reading electronics of the reading camera, the complex electronic device analyzes the color of the granulate.

  After analysis of the granulate, the machine automatically determines which granulate is repelled. This adjustment is performed by the machine operator, and the machine removes what is defective by color from the flow of particulates by means of an electronic pneumatic ejector valve based on the machine settings.

  Conventionally, this type of machine is basically composed of a feeding hopper, an electromagnetic vibrator with a vibrating chute, a belt conveyor, an optical reading electronic camera, and an ejector valve.

  Also different from conventional machines are the transport of granules in the machine and modern electronic systems.

  Conventionally, these machines are equipped with an electromagnetic vibrator with a vibrating chute for supplying granular materials and adjusting the flow rate, but granular materials were previously transported by a belt conveyor, but now they are transported by a conveying chute. Done. In addition to being a modern technology compared to current machines that use transport chutes, electronic color sorters use a belt to transport granular materials for sorting, as well as optical reading. The speed of the granular material passing through the center of the electronic camera is also different.

  Electronic particle sorters by color using a belt conveyor have a limited range. This is because when the granular material passes through the optical reading electronic camera, the speed of the belt conveyor cannot be increased to increase the production amount. This is because if the speed of the belt conveyor is changed, the target granular material will be disengaged from the reading center of the camera, causing a problem in the entire analysis system of the machine. This type of machine is also limited in scope in other applications. This is because the production volume can only be increased by an electromagnetic vibrator with a vibrating chute, the speed of the belt conveyor must be constant and there must be no fluctuations.

  The electronic particle sorter by color using a transport chute has increased the speed of the granulate through the optical reading electronic camera.

  By replacing the belt conveyor with a transport chute, the speed of the granular material increases and the productivity of the machine increases.

  The conveying chute is fixed in an inclined manner using an attractive force so that the speed increases when the granular material passes through the reading camera of the machine. Nevertheless, the machine output is still controlled by an electromagnetic vibrator with a vibration chute.

  The electromagnetic vibrator with the vibration chute has a limited range of functions and production volume adjustment. A pulsed magnetic circuit, which supplies power to the vibrator coil, also creates a pulsed magnetic field that moves the vibratory chute of the vibrator back and forth in the horizontal direction. The production of the machine is adjusted by the movement of the vibration chute. The supply amount increases or decreases depending on the pulse frequency of the vibration chute. That is, according to the driver's setting, the production volume increases or decreases according to the ratio of defective products identified by color in the product or according to the capacity limit of the machine.

  Various improvements have been made in pulse adjustment with this type of vibration chute, but the horizontal movement is used to supply the electronic granular material sorter of the pulse adjustment system, and a product chute (small lot) is conveyed to the chute. It is made at the initial stage of conveyance by and released for reading by the optical electronic device of the reading camera. These lumps make it difficult to read by the camera's optical electronics at certain levels of production, thus limiting the precision of production and machine sorting and increasing the amount of waste, i.e. the proportion of granules that the machine repels. .

  In order to solve the above-mentioned problem and to provide a more practical and high-performance supply amount regulator, the inventor has intensively studied, and in the supply of the electronic granule sorter, a product that is pulse-vibrated with a vibrator. We have arrived at the present invention aimed at preventing the formation of lumps and have developed a new supply regulator.

  Another novelty of the present invention resides in the use of a motor-driven supply belt conveyor used as a supply device and supply amount regulator in the machine production flow instead of the conventional pulse electromagnetic vibrator.

  The device according to the present invention can be better understood from the detailed description in the attached drawings, and can be understood more easily in combination with the following symbols.

  As described above, the present invention has a hopper (2) for storing granular materials to be sorted and a conveyance / supply chute (5) for conveying the granular materials to an outlet (6) with an optical electronic sensor (8) for reading. ) By a motor (3) that drives the conveyor belt conveyor (4) that transports the granular material to the) and a reading camera that operates the ejector air valve (7) with the firing nozzle (9) for sorting by sorting the granular material by color It is characterized by being configured.

  The transport chute (5) receives the granular material and transports it in an aligned state until it is discharged from the outlet (6), where reading is performed by a set of reading electro-optical sensors (8).

  The motor-driven supply belt conveyor (4) is used as a supply control and a supply machine for the production flow of the machine (1), and the granular material of the hopper (2) is transferred to the conveyance chute (5), and the conveyance chute is granular. The body is received (enlarged part in Fig. 2), aligned, transported to the outlet (6), and read by the reading optical electronic sensor (8) set of the sorter (1).

  Due to the electronic system with the supply belt conveyor (4), the production volume of the machine (1) is controlled not by increasing the frequency of the pulses of the electromagnetic vibrator (not shown) but by increasing or decreasing the speed of the motorized supply belt conveyor (4). The

  Supply of the machine (1) by the supply belt conveyor (4) and adjustment of the supply amount are performed linearly, and a lump of granular material is formed on the conveyance chute, and the optical electronic sensor of the reading camera (10) of the machine (1) There is no direct interference with reading by (8) and no loss.

The whole side view of the supply amount regulator which is partially enlarged and indicated by a dotted line and an arrow in order to show details of the alignment state and the stroke of the granular material in the chute.
