Description

[Detailed description of the invention] The present invention relates to an improvement in a gutter fixing device for a color sorter.

The gutter body fixing structure of the downflow gutter in a color sorter is simplified as much as possible, and the shaft body to which an arbitrary number of gutter is fixed is moved up and down to continuously clean and repair multiple photoelectric sorting chambers. The purpose is to develop and provide a device that is easy to implement, maintains good sorting accuracy, and downsizes the entire device.

To explain the present invention with reference to an embodiment, a vibrating grain feeder 3 with a vibrating device 2 is installed on the upper part of a sorter frame 1, a feed hopper 4 is provided on the supply side, and the cross section is approximately cut on the discharge side. The V-shaped downflow gutter 5 is connected and fixed to the gutter body mounting bracket 6, and the lower end of the downflow gutter 5 is connected to the upper part provided in the formwork 8 of the photoelectric sorting chamber 7 in which the photoelectric device and the injection device are installed. The light source 10 and the light-receiving element 11 are fitted into the insertion opening of the lid body 9 and fixed, and the light source 10 and the light receiving element 11
A photoelectric device consisting of a photoelectric device is installed facing each other, and an injection nozzle 12 of an injection device is provided in the vicinity thereof and each is fixed to the inner circumferential wall surface of the formwork 8. Also, a grain collecting cylinder 13 is provided on an extension of the trajectory A to form a mold. It is fixed to the bottom wall of the frame 8, and an outlet 14 for discharging the different color particles is provided on the negative side of the bottom wall.

The gutter body mounting bracket 6 integrally connects an upper fitting portion into which the gutter body is fitted and fixed by the stopper 15 and a lower fitting portion which locks the gutter end through a shaft body. The upper fulcrum 16 and the lower fulcrum 17 are pivoted and fixed to both upper and lower shaft bodies 18 and 19, which are horizontally suspended between both side frames of the machine frame 1. are connected to the upper fulcrum 22 and lower fulcrum 23 of the fixed base 21 mounted on the side wall plate 20 of the side wall plate 20 by connecting rods 24, respectively, and each of the downflow troughs 5... is connected to the shaft 18 or the connecting rod 24. An actuating device 25 is connected to the actuating device 25 for vertically moving the actuating device 25, and the driving portion of the actuating device 25 is connected and fixed to a stopper 26 fixed to the wall of the machine frame 1.

Figure 3 shows each gutter body mounting bracket 6 of each of the above-mentioned downflow gutter 5...
An example is shown in which an actuating device 25 is provided at one end of both shaft bodies 18 and 19 which are arranged in parallel and pivotally connected, and a similar actuating device 25 is provided at the other end of both shaft bodies 18 and 19. Number of drains 5
It is formed so that it can move up and down together.

Furthermore, the actuating device 25 in FIG. The gutter body mounting bracket 6 is formed to move up and down by being connected to the connecting rods 24 of 3
At the same time, the electric motor 32 of the gear 31 is fixed to the side wall of the fixed base 21, and the connecting rods 24, 24 are formed so as to rotate up and down by the rotation of the worm gear 31.
The illustrated actuating device 25 is a screw shaft 34 driven by an electric motor 33.
is inserted into the screw fitting 35 pivotally connected to the connecting rod 24, and
The electric motor 33 is fixed to a fastener 26 fixed to the machine frame 1, and the gutter body mounting bracket 6 is configured to move up and down by rotation of the screw shaft 34.

With the above-mentioned configuration, the particles mixed with different colored paddy in the raw material flowing down from the supply hopper 4 to the vibrating grain feeding trough 3 flow down into the lower flow trough 5 by the vibration action of the vibrating grain feeding trough 3, and are transferred to the photoelectric sorting chamber 7. The liquid flows out in a flight shape along a predetermined flow trajectory A.

In the sorting chamber T, the light-receiving element 11 receives the reflected light beam of the different-color particles and issues a signal, and the detection signal activates the injection nozzle 12 to emit a jet at the appropriate time. The particles depart from the flow trajectory A, and the detached particles flow down from the discharge port 14 and are removed, and the particles depart from the flow trajectory A.
The sorted particles flowing out along with the grain collecting cylinder 13 are directly removed from the machine and sent to the next process.

In the above-mentioned sorting process, in the photoelectric sorting chamber 7, scattered dust from particles generated by the blast action adheres to each transparent wall surface of the light source 10 and the light receiving element 11, and the amount of light emitted from the light source 10 decreases. If the detection sensitivity of the light-receiving element 11 is affected, causing a malfunction in its detection and sorting action, or if the machine inside the chamber 7 breaks down, the upper lid 9 of the photoelectric sorting chamber 7 is removed and the transparent wall surface is removed. It is necessary to clean the machine or replace or repair the malfunctioning machine part.

As shown in FIG. 6, a conventional gutter body fixing device for a downstream gutter has a rotating frame 36 pivoted to rotate in a semicircular arc shape to a ladder-shaped main body made of a combination of prismatic members. This is because the structure is such that an angle adjustment board 31 having a long hole in two force directions and a plurality of bolds is fixed, and a support gutter body part 39 having a V-shaped cross section into which the downflow gutter 38 can be fitted is attached to the adjustment board 37. When attaching or detaching the upper lid 40 of the photoelectric sorting chamber or attaching or detaching the downflow gutter 38, the rotating frame 36 must be rotated to the position shown by the two-dot chain line in the figure. Gutter body fixing part 36, 37, 3
8 and 39 has expanded, making it necessary to increase the size of the main body structure that houses them, and the angle adjustment board 37 and support gutter body formed separately from the rotating frame 36. Since the sections 39 are combined with each other, the assembly of the device becomes complicated, and the positioning of the downflow gutter 38 with respect to the flow trajectory A is complicated. This method has drawbacks such as making it difficult to automate the mechanism used to do so.

Accordingly, the gutter body fixing device of the present invention has a structure in which each actuating device 25.
25, the gutter body mounting brackets 6 of each downflow gutter 5 are moved up and down together via both shaft bodies 18, 19, so that each lid of a plurality of photoelectric sorting chambers 7 can be moved up and down together. By sequentially attaching and detaching the body 9, cleaning and repair thereof can be easily and continuously performed, and the sorting accuracy can be improved.

In addition, since each downflow gutter moves with its gutter end fixed, the positioning of the flow path A is accurate and easy, and the entire mechanism is lightweight, so a large number of downflow gutter can be moved up and down with a simple actuation device. Moreover, the structure is simplified, the overall size of the device is reduced, and the manufacturing cost is reduced.
