Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color sorter for eliminating defective products from rice grains and other raw materials to be sorted. Conventional color sorters include, for example, those shown in FIGS. ◎ That is, this color sorter 1 mainly consists of an inlet hopper 3 into which raw materials to be sorted (hereinafter simply referred to as raw materials) 2 are input, an electric tl&yida [conveyor] 4 that adjusts and averages the flow rate, and a raw material O alignment.・O first chute 5 for falling
02 pump house 116, which is composed of multiple parts, such as I) pump house section 6 for inspection and sorting, and second shade 7 for removing mourning items.
0 inside the lamp house part 6 is covered with white color,
A pump 8, an optical detector 9, an ejector 10 as a high-speed air gun, a background 11 for reference color judgment for defective product judgment, etc. are provided. 12 is left unused. In the conventional O color sorter 1 like this, the raw material is first fed into the 2Fi inlet hopper 6, and then the electromagnetic feeder 4 feeds it at a predetermined speed. 1 chute 5. The raw material 2 slides down along the sliding part 5aK of the first shoe) 50, gradually accelerates, aligns itself and falls, and freely falls from the lower end 5b of the first shoe) 50, passing between the photosenner 9 and the background 11. It passes through and proceeds in the direction of the second chute 7.In the lamp house section 6, the lamp 8 reveals the raw materials 2, that is, the raw materials 2 aligned and falling (by the lower end 5), and the raw materials 20 are seen from both sides of the front and back. The photo sensor t9 senses the reflected light, and the electronic circuit in the controller 12 compares it with the reference color of the background 110 to determine whether the raw material 20jIL is present or not. The ejector 10 blows compressed air to the particles 2 in the raw material 2 that are determined to be defective as a result of the judgment O, and the O particles 2a are determined to be defective.
The granules 2b, which are determined to be waste products, are blown away from the alignment and falling flow of the raw materials 2 and taken out from the unnecessary product outlet 16. On the other hand, the granules 2b, which are determined to be obsolete products, pass through the 100 m direction of the SOTT ejector and are sent to the second Kuwait 71ell. Therefore, the raw materials 2 must be aligned and fall in order for the color sorter 1 to detect Kofu Arashi products. →, Even if we adopt the falling part 5aKIl 0 gutter shape 0 cut-out carved shape, the moisture content of raw material 2 1,
Due to the presence of deposits [e.g. machine]), when condensation occurs in the above part 5aK, the raw material 2#i polymerizes on the above part 5 haze), #
611. At times like this, line up and
There was a problem that the falling #l was too low to form and the sorting efficiency was divided accordingly. By placing a linear object in the area where the raw material slides down, it is possible to always maintain accurate alignment from the bottom of the chute.
This aims to solve the conventional O problem by making it possible to obtain a falling flow.

The details of ζO development will be explained below with reference to FIGS. 4 to 7. In the following, parts that are the same or similar to the conventional ones will be designated by the same reference numerals and will be referred to as 10 to omit redundant explanation.

Figures 4 to 6 show examples of this invention. Chute [1st shell 150 raw materials 0 slips] Falling part 5
In aK, a plurality of linear bodies 15 are arranged in parallel in the longitudinal direction [in the direction of the arrow in FIG. , piano wrap, wire, etc. can be used, and El-F16.1
7.18 fCWj@stLru vx-') 16.
If either 17%18 is the drive row 2, the linear body 15
can be made into a "moving linear body" whose speed can be freely adjusted.

Also, by changing the position of the row) 16.17, the linear body 15
The zero angle (#) can be adjusted freely. Furthermore, when the linear bodies 15 are defined as "moving linear bodies", the moving direction can be in the direction of arrow B or in the direction of arrow B. The distance (d) between the linear bodies 15 is , the %O is appropriately selected so that the islands are aligned according to the size of the raw material 2, and the %O does not fall below the island.

Next, to explain the action, the raw material 2 fed from the electromagnetic feeder 4 to the chute 5 is
When it slides down on the linear body 15, the photosenner 9 is exposed to a collision distance (a plurality of them are stretched in parallel and are naturally aligned by the round linear body 15, and the lower end 5- of the pseudo 50). and the background 11, and fall freely as an aligned/falling flow. Adjustment of linear body 150 angle (θ), speed adjustment, moving direction [arrow direction or qB direction] Ow change.
Before selection etc., the raw material 2 is placed on the linear body 15 and the efficiency true (
For example, if the linear body 15 is moved in the direction of arrow B, the raw materials 2 will be more accurately aligned at a slow falling speed, and the sorting 1 It is possible to perform accurate sorting by seismic motion.Also, by adjusting the speed, alignment can be easily performed by adjusting the speed. 1 thing to do
10 Figure 7 (a), (showing examples of rumors and other Oigon examples) When the whole 50 is formed of the linear body 15 [marked in Figure 7] and a part When formed from the linear body 15 (117
Figure (b)] is shown, and the disconnection of v:L-)5**
The shape is approximately triangular gutter-shaped.In this way, it is possible to adopt various shapes to combine the linear body 15t with the chute 5.In addition, other configurations and functions will be discussed with the company. Since this embodiment is substantially the same as the previous embodiment, repeated explanation will be omitted. Furthermore, in the above description, the case where the linear body 15 is movable has been explained, but of course the mechanical body 15 may be in a stationary state. The chute that aligns and drops the raw materials to be sorted is formed by a plurality of linear bodies stretched in parallel in the longitudinal direction, so that the part where the raw materials to be sorted slide down is formed by a plurality of linear bodies stretched in parallel in the longitudinal direction, so that moisture and deposits on the raw materials to be sorted are removed. It is possible to ensure the alignment of the raw materials to be sorted without being affected by
Since the alignment and falling flow from the lower end of the chute is extremely accurate, the sorting efficiency can be improved.Also, if the linear body is a moving linear body whose angle and speed can be adjusted freely, the above-mentioned results can be achieved. It has many effects such as being able to more efficiently arrange the raw materials to be sorted.
