本考案は穀類、豆類又は樹脂ペレツトといつた
粒状物中に混入する異色粒子を受光素子によつて
検出するとともに、エジエクターにより除去する
粒状物色彩選別機に係り、特に、粒状物色彩選別
機の供給樋に関する。[Detailed description of the invention] [Industrial application field] The present invention detects different colored particles mixed in granular materials such as grains, beans or resin pellets using a light receiving element, and removes the granular materials using an ejector. The present invention relates to a color sorter, and particularly to a supply gutter of a granular color sorter.
この種の粒状物色彩選別機は、原料の粒状物
が、傾斜して設けた供給樋（シユート）を高速度

のである。
In this type of granular color sorter, the raw material granules slide down a slanted supply gutter (chute) at high speed, and fall through a photoelectric sorting unit installed on an extension of the feed gutter. Different color particles and standard color particles are distinguished, and the different color particles are removed by an ejector.
ところで、供給樋から光電選別部に連続的に供
給される粒状物の束状の流れ（以下「流束」とい
う）は、小さいほど選別精度が高く、大き過ぎる
場合は、流束の中心部の粒状物き光源からの照明

そのため、前記流束の大きさはおのずから制限さ

精度で選別・除去する場合は一つの供給樋（１流

成するのが普通であり、したがつて、毎時4000Kg
の白米を選別するためには、１台に20〜30チヤン
ネルを装備した色彩選別機が設けられる。 By the way, the smaller the bundle-like flow of particulate matter (hereinafter referred to as "flux") that is continuously supplied from the supply gutter to the photoelectric sorting section, the higher the sorting accuracy is. Illumination from a light source with particles cannot be received, leading to detection errors by the light receiving element.
Therefore, the size of the above-mentioned flux is naturally limited, and for example, in the case of sorting and removing different colored particles mixed in polished rice with the desired precision, it is approximately 200 kg/H per feed gutter (one flux supply path). is said to be the maximum limit. In addition, it is common to provide a light receiving element and an ejector for one supply gutter to form a channel, and therefore the flow rate is 4000 kg per hour.
In order to sort white rice, one color sorting machine is equipped with 20 to 30 channels.

選別精度が低下する。そこで、ひん繁に供給樋を
点検し、付着物を取り除く必要がある。 Furthermore, what is important for highly accurate sorting with this type of color sorter is that the particulate matter (flux) that is supplied from the supply hopper to the supply gutter is dispersed, that is, it is not scattered or transferred. The purpose is to let the material slide to the photoelectric sorting section in an orderly manner without having to feed it while moving. Therefore, if bran or other substances adhere to the supply gutter, the flow rate of the flux will decrease, causing the timing of the ejector to shift and removing standard color particles, or disrupting the flow trajectory and removing different color particles. Due to the inability to detect different colored particles, it may not be possible to remove different colored particles, resulting in a decrease in sorting accuracy. Therefore, it is necessary to frequently inspect the supply gutter and remove any deposits.

The width of the gutter body fixing frame 61 is increased. in this case,
The gap G between the back surface 62 of the gutter body fixing frame 61 and the attachment/detachment locking fitting 63 is important for attaching/detaching the gutter body fixing frame 61. For example, the surface roughness of the gutter body fixing frame 61 or the attachment/detachment fittings 63, 63 may make attachment/detachment difficult, and if there are uneven parts, curved distortion, etc., insertion/insertion becomes impossible. Alternatively, the sorting accuracy may be reduced because it cannot be secured to the normal position. In addition, if the above-mentioned phenomenon is anticipated and the gap G between the back surface 62 of the gutter body fixing frame 61 and the attachment/detachment fitting 63 is formed in a loose fit shape, the gutter body fixing frame 61 can be Due to irregularities or distortions existing on either the back surface 62 or the attachment/detachment fitting 63,
The gutter body fixing frame 61 was attached in an inclined state when it should have been attached horizontally on the left and right, which disturbed the normal flow trajectory of the particulate matter and caused poor sorting accuracy.

れる。 The different-colored particles thus discharged into the different-colored particle discharge gutter 18 may be taken out of the machine from the outlet 20, but normally, along with the different-colored particles, a certain amount of standard-colored particles are also removed from the flow trajectory A by the ejector 16. This requires re-selection. In this case, by operating the switching valve 19 of the switching unit 22, the unique particles are transferred to the secondary supply hopper 28 by the lifting machine 21.
The standard color particles and the different color particles are re-sorted into standard color particles and different color particles by the same sorting action as in the above-mentioned primary sorting section 26, and the standard color particles are discharged from the non-defective product outlet 23 and the different color particles are discharged from the defective product outlet 25. Each is ejected from the aircraft.

In order to prevent this from causing failure in the detection of particles of a different color, the surfaces of the transparent wall plates 10 and 14 are cleaned and removed by a cleaning device 15 under the control of a timer or the like. Further, particulate matter scattered from the vibrating supply gutter 3 and the like falls onto the downstream guide plate 34 and flows out into the different-color particle discharge gutter 18.

のではない。 During the above-mentioned sorting action (see Figures 3 and 5), dust etc. adhering to the granules are removed from the supply gutter 36.
If the particles adhere to the surface of the supply gutter 36, it will inhibit the flow of the particles down the supply gutter 36 surface. As mentioned above, if there is something stuck to the supply gutter 36, the falling speed or trajectory of the granules will be disturbed and the sorting accuracy will be degraded. To prevent dust from adhering to the supply gutter 36 due to dew condensation, the heater 4
Although it is preferable to take measures to prevent adhesion by heating the supply gutter 36 using the method 7, although it has the effect of reducing the number of manual cleaning and removal operations, it cannot completely prevent adhesion.

That is, it is the protrusion 4 of the supply gutter 36 that comes into contact with the supply gutter holder 32.
2 and 42, and the bonding area of this adhesive portion 43 to the supply gutter holder 32 is very small, and the frictional resistance when attaching and detaching the supply gutter 36 is small, making it easy to attach and detach. It becomes easier. In addition, since only the lower ends of the protrusions 42, 42 on both sides of the supply gutter 36 are bonded, there is no possibility of installation failure due to surface roughness or distortion of the supply gutter holder 32, and the locking metal fittings 44 into a locking hole 45 provided in the supply gutter mounting base 32 or detached therefrom, the supply gutter 36 can be attached and detached accurately and easily.

場合もある。 Note that the shape of the groove of the supply gutter formed in multiple channels is not limited to the one shown in the diagram, but can be replaced by selecting a flat-bottomed shape or a V-shaped shape as appropriate depending on the normality of the granules, and the number of channels can also be changed to any number. What is formed is a matter of course. Furthermore, as shown in FIG. 3, if the supply gutter is integrally molded from aluminum, resin, etc., mass production can be facilitated, and the machining accuracy is more precise, which improves the sorting accuracy. Furthermore, after the surface layer of the supply gutter is alumite-treated, a fluororesin may be applied to strengthen the prevention of deposits.

As explained above, according to the present invention, the supply gutter is integrated to reduce the construction cost, and the bottom of the feed gutter formed in multiple channels is prevented from coming into contact with the supply gutter mounting base. Since it is formed so that only the lower end of the protruding part with both sides protruding beyond the bottom of the supply gutter is attached to the supply part mounting base,
When attaching and detaching the supply gutter, the sliding friction resistance between the supply gutter and the supply gutter mounting base is reduced to facilitate attachment and detachment, and since it is not affected by the surface roughness or distortion of the supply gutter mounting base, Even if the supply gutter has multiple wide channels, each time it is installed, it can be installed accurately in the correct position without distortion or twisting, and the accuracy of sorting granular materials can be ensured normally, and furthermore, the operation can be stopped for attachment and detachment of the supply gutter. It has the effect of reducing time.
