Detailed ways

An embodiment of the dry food sorting device of the present invention and a dry food sorting line equipped with the sorting device will be described below with reference to the accompanying drawings. In addition, below, let the left side in FIG. 1 be a front side, and let the right side in FIG. 1 be a rear side.

As shown in FIG. 1 , the dry food sorting line 200 includes a dry food sorting device 1 and an image inspection device 100 . First, the dry food sorting device 1 will be described.

The dry food sorting device 1 has an inclined conveying part 6 arranged obliquely on a sorting machine table (not shown). The upstream part (front part) of the inclined conveyance part 6 is vibrating and capable of conveying, and the downstream part (rear part) of the inclined conveyance part 6 is constituted by inclined plates. Examples of the upstream portion (front portion) of the inclined conveying unit 6 include a vibrating conveyor belt, a vibrating conveying device, a vibrating sorting device, and the like. The two sides of the inclined conveying part 6 are additionally provided with shrouds (not shown), and the upper upstream side (upper front side) is equipped with a quantitative supply device (not shown) for processed products, so that the processed products From the upstream side (front side) to the downstream side (rear side). A gap 2 for blowing out air for sorting is formed on the downstream side of the inclined conveyance unit 6 . The downstream side of the gap 2 is provided with a baffle plate 3 whose position in the vertical direction can be adjusted. In addition, the processed products are dried fish, dried whitebait, dried vegetables, dried kelp and other dried foods mixed with foreign matter. Hereinafter, among the foreign substances, those whose specific gravity is higher than that of the dry food are called heavy foreign substances, and those whose specific gravity is lower than the dry food are called light foreign substances.

An air supply fan 15 is installed below the inclined conveying part 6, and the air volume can be increased or decreased by inverter control. On the outlet of the air supply fan 15, a blowing nozzle 16 is installed toward the direction of the gap 2.

In addition, a heavy foreign matter guide passage H is formed below the gap 2 to receive and guide downward heavy foreign matter that is hardly blown up by the wind of the air supply fan 15 but falls down. In addition, in the rear-downward direction between the upper end of the baffle plate 3 and the lower end of the rectifying rear plate (described in detail later) 9 , a product guide channel M for receiving dry food and guiding it downward is formed. In addition, between the upper end of the baffle plate 3 and the lower end of the rectified rear plate 9 is a position where dry food is blown by the wind from the air supply fan 15 .

A suction cover 10 is attached to the rear upper part of the inclined conveyance part 6 . The suction hood 10 includes: a front panel 7 , a side panel 4 , a rear panel 8 and a rectifying rear panel 9 . The lower part of the front panel 7 (also referred to as rectification wall) expands to the outside of the suction hood 10 to rectify the wind from the air supply fan 15 . Moreover, the rectification rear board 9 which rectifies the wind from the air supply fan 15 is attached to the lower end of the rear board 8. As shown in FIG. The upper end of the rectifying rear panel 9 is rotatably arranged on the rear panel 8 by using a hinge 11 , and its angle relative to the rear panel 8 can be adjusted by using an adjusting member 12 . The adjustment piece 12 is screwed into the threaded hole of the ear part 17 where the side plate 4 is installed. That is, the straightening rear plate 9 adjusts the angle through the adjusting member 12 to properly rectify the wind from the air supply fan 15 . As described above, since the inside of the suction hood 10 is a space for rectifying the wind from the air supply fan 15, it is also called a guide rectification space.

In addition, a horizontal pipe (an example of a side guide portion) 14 is disposed on the upper portion of the suction hood 10 . As shown in FIG. 2 , one opening of the horizontal pipe 14 is closed, and the other opening is connected to a cyclone cleaner 20 via a bellows pipe 13 . As shown in FIGS. 4 and 5 , the horizontal pipe 14 has a suction port 18 formed on a circumferential surface to send wind from the suction cover 10 . The suction port 18 is set such that the area on the side of the other opening (the side connected to the bellows 13 ) is small, and the area on the side of the one opening is large. That is, the wind speed on the side of the other opening of the suction port 18 is greater than the wind speed on the side of the one opening. Therefore, the suction port 18 sucks in more light foreign matter carried by the wind on the side connected to the bellows 13 (shown as the "high-speed suction" side in FIG. 5 ). Therefore, the horizontal pipe 14 moves the light foreign matter horizontally toward the bellows side while deflecting the light foreign matter to the side of the bellows.

As shown in FIG. 2 , the cyclone vacuum cleaner 20 is connected with an exhaust pipe 21 for exhausting at the upper part, and a light foreign object storage box L is provided at the lower part for receiving and storing the light foreign objects collected by the cyclone principle.

The image inspection device 100 will be described below.

As shown in FIGS. 1 and 3 , the image inspection device 100 includes: a conveyor belt 101 that receives the dry food taken out from the product guide channel M and conveys it to the downstream side; and an image inspection unit 102 that photographs and inspects the conveyor belt. 101 conveyed dry food.

The operation of the dry food sorting line 200 will be described below.

As shown in FIGS. 1 and 3 , the product to be processed is discharged from the quantitative supply device to the upper upstream side (front side) of the inclined conveying unit 6 , and is conveyed downward on the inclined conveying unit 6 . At this time, by vibrating the processed products at the front portion of the inclined conveyance unit 6, only processed products of an appropriate size can be sorted. Then, after the processed product of an appropriate size reaches the gap 2, it receives the air (wind) blown by the air supply fan 15 from below.

The heavy foreign matter mixed in the product to be processed will not float even if it is blown by the wind, and will not go over the baffle plate 3, but will fall from the gap 2 as it is, and will be guided to the heavy foreign matter after passing between the blowing nozzle 16 and the baffle plate 3 Guide passage H, and be taken out to dry food sorting device 1 outside. In addition, the route of the heavy foreign matter is represented by the vector hf in FIG. 1 .

In addition, among the dry food and light foreign matter passing through the gap 2, the dry food falls under the influence of gravity near the baffle plate 3, is guided to the product guide channel M, and is taken out of the dry food sorting device 1. In addition, the path of the dried food is represented by the vector mf in FIG. 1 .

In addition, the light foreign matter is lifted by the rectified wind sucked into the hood 10 . Then, the light foreign matter is sucked into the horizontal pipe 14 from the suction port 18 by the wind, and then sent to the cyclone type vacuum cleaner 20 through the bellows pipe 13 . In addition, the path of the light foreign matter is represented by the vector lf in FIG. 1 , FIG. 2 and FIG. 4 .

The wind speed in the suction port 18 of the horizontal pipe 14 increases closer to the side connected to the bellows pipe 13 . Therefore, the amount of light foreign matter sucked into the suction port 18 increases on the side connected to the bellows 13 and decreases on the opposite side.

In addition, the cyclone cleaner 20 stores the light foreign matter in the light foreign matter storage box L by using the principle of the cyclone, and exhausts it from the exhaust pipe 21 .

On the other hand, as shown in FIG. 3 , the dried food taken out of the dry food sorting apparatus 1 falls onto the conveyor belt 101 . Thereafter, the dried food is imaged and inspected by the image inspection unit 102 while being transported on the conveyor belt 101 .

In this way, according to the dry food sorting device 1 and the dry food sorting line 200 equipped with the dry food sorting device 1, since the rectified wind is used to sort the dry food according to the specific gravity, it is not necessary to use vibration and high-speed The airflow impinges on the dry food, which not only prevents damage to the dry food, but also reduces vibration and noise.

In addition, since the wind from the fan 15 is rectified and the wind pressure is effectively used, a large-scale fan capable of blowing high-speed airflow and blowing dry food to a remote space is not required, and the occupied installation area can be reduced.

Moreover, by adjusting the position of the rectifying rear plate 9 with the adjustment member 12, the wind in the suction cover 10 can be rectified into a wind suitable for drying food, so not only can sorting dry foods with various specific gravity, but also can reduce the risk of foreign matter. Remove precision.

Furthermore, since the horizontal pipe 14 deflects the light foreign matter to the suction bellows 13 side, and the light foreign matter moves in the horizontal direction to the bellows 13 side, the amount of light foreign matter dropped during a power failure can be reduced.

In addition, by vibrating and sorting the products to be processed at the front portion of the inclined conveyance unit 6, the products to be processed of an appropriate size can be sorted, so the foreign matter removal accuracy can be further improved.

In addition, according to the dry food sorting line 200, since the dry food sorted by the dry food sorting device 1 is further inspected by the image inspection device, the foreign matter removal accuracy can be further improved.
