Abstract

PROBLEM TO BE SOLVED: To enable on easy adjustment of space between a color detecting unit and an object to be detected by freely elevating and lowering the lower end side of a feeding mechanism. SOLUTION: In an inclined chute 1 which is a feeding mechanism with a large number of V-shaped chute grooves, an object to be detected W is supplied for each chute groove from a supplying device 4 and dropped along a drop track R. Color detecting units 21 are installed in parallel below the drop track R each in correspondence with the chute groove of the inclined chute 1 in a location at an appropriate distance from the tip of the inclined chute 1. Each of them independently operates and informs a high-speed solenoid valve 32 corresponding to a sorting unit 3 from an amplifier unit 21 of the detection of an object to be detected W different from a regular color and tone. Then an air injecting nozzle 31 connected to the high-speed solenoid valve 32 sprays air to the different object to be detected W off the drop orbit R to separate it from others. At this time, as an eccentric cam 6 freely elevates and lowers the lower end part of the inclined chute 1 supported by a pivot 8, it is possible to adjust the inclined chute 1 to a desired height.

2. Description of the Related Art A color sorting apparatus is used for detecting an object (work).
The light is applied to the surface of the object, and the reflected light is detected to identify the color and color tone of that location for each detected object, discriminate and sort the objects, and the main part is the feed mechanism of the detected object And a color detecting unit comprising a light irradiating element for irradiating light to the surface of the detected object and a color detecting element for detecting the color, color tone, shading, etc. of the reflected light, and the color and color tone detection from the color detecting unit And a sorting unit that receives the output and determines or sorts the object. In contrast to the conventional color selection device, in which the color detection unit is fixed in place on the transfer conveyor and detects the color of the upper surface or side surface while transferring the detected object. In recent years, an object to be detected is sequentially fed by a feed mechanism such as a belt conveyor or an inclined chute, and is ejected from the tip of the feed mechanism, and a color detection unit is attached to a lower side of a fall trajectory of the feed mechanism. A method of detecting a color or the like of a lower surface of a detection object falling through a tip has been attempted (for example, Japanese Patent Application No. 8-355142). This new color sorting device can keep the distance between the surface to be detected of the detected object and the color detection unit constant irrespective of the variation of the size and shape of the detected object. Since the color detection element is formed of glass fiber, the color detection unit is significantly reduced in size, and can be brought close to the detected part within several mm.

The color detection unit is:
The smaller the distance between the detected object and the detection surface, the narrower the detection range becomes, and the higher the detection accuracy becomes. As a result, it becomes possible to select and send a small detected object by narrowing the distance between the objects. However, if the interval is too small and the detection range of the color detection unit becomes smaller than the range of the detection surface of the detection object, a detection error may occur. Therefore, the distance between the color detection unit and the detection surface of the detection object is determined according to the size and shape of the detection object.
It is desired that the setting be made as narrow as possible without causing a detection error. However, in the conventional color selection device, since a feed mechanism such as an inclined chute is fixed to the body, in order to adjust the distance between the color detection unit and the detection surface of the detection object, the fall trajectory of the detection object is required. On the other hand, it is necessary to adjust the position of the color detection unit. However, this adjustment operation is extremely difficult,
In actual work, at the expense of detection accuracy and work efficiency, the distance between the color detection unit and the detected object is set wide in advance, and it is constant even if the size and shape of the detected object are different. I had to work under the conditions described above. SUMMARY OF THE INVENTION It is an object of the present invention to provide a color selection device capable of easily adjusting a distance between a color detection unit and a surface to be detected of a detected object.

FIG. 1 shows a tilted chute 1 with an eccentric cam 6.
This shows an example in which the lower end of the tilting chute is raised and lowered. A supporting shaft 61 is provided below the lower end of the tilting chute 1, and the eccentric cam 6 is attached to this. The lower end is supported by the eccentric cam 6. Although not shown, a reciprocating rotation mechanism such as a crank system or a ratchet system is attached to the support shaft 61 so that the support shaft 61, in other words, the eccentric cam 6 can be rotated in the left-right direction. Thus, the lower end of the inclined chute 1 can be adjusted to a desired height. In the drawing, a coil spring 7 is contracted between the inclined chute 1 and an appropriate position of the machine so that the inclined chute 1 is always pressed against the eccentric cam 6 with a constant force.
