Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a dry small fish sorting machine that sorts dried small fish according to size.

Conventional technology Traditionally, the work of sorting dried small fish by size was
In addition to manual methods, a sorting machine is used that vibrates a flat net to cause dried small fish to fall through the mesh of the net and sort them out.

Problems to be Solved by the Invention However, the sorting machine using the above flat net has the following problems.

That is, a. Dried small fish have many variations in shape, so the accuracy of size selection is poor.

b Depending on the time of use, the net becomes clogged with dried small fish, and the sorting operation must be stopped to remove it, which significantly reduces the efficiency of the sorting operation.

c) Forcible vibrations are applied to weak dried small fish, which damages the dried small fish and reduces its commercial value.

d The vibration and noise associated with the sorting work is very loud.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a dry small fish sorter that can sort out irregularly curved dried small fish with high precision.

Means for Solving the Problems In order to solve the above-mentioned problems, the first means of the dry small fish sorting machine of the present invention is to have a cylindrical sorting rotor arranged laterally so as to be freely rotatable around its axis. death,
A plurality of spokes are arranged along the axial direction of the body of the sorting rotor at regular intervals in the circumferential direction.

In addition to the first means, the second means includes providing a sorting rotor with a plurality of sorting chambers with different spoke intervals, and arranging the sorting chambers so that the spoke intervals gradually increase. An inlet for dry small fish is provided at the end of the sorting chamber where the distance is the smallest, and a spiral feeding plate is provided on the inner circumferential surface of the spokes of the sorting rotor to send the dried small fish from the sorting chamber where the spokes are narrowly spaced to the wider sorting chamber. It is something.

Furthermore, the third means includes, in addition to the first means,
A vibrating ring having a diameter larger than the body is rotatably fitted onto the body of the sorting rotor, and a weight is provided at an arbitrary location on the vibrating ring.

Effect According to the first configuration, by putting dried small fish into the rotating sorting rotor, dried small fish smaller than the spacing between the spokes can be sorted out by falling from between the spokes, and dried small fish that are not dropped can be sorted out from between the spokes. is only agitated by the sorting rotor and is not subject to strong vibrations like conventional methods, making it less likely to be damaged. In addition, dried small fish that are clogged between the spokes tend to fall when rotated to the top, so clogging occurs very rarely.

Furthermore, when the sorting rotor rotates, the vibration ring is rotated due to the frictional force between the spokes and the vibration ring, and the lowest weight is lifted. When the weight rises to a predetermined position, a gap is created between the spokes and the top of the vibrating ring, and when the weight of the weight overcomes the frictional force, the vibrating ring reverses and returns to its original position. During this reversal, the vibrating ring hits the spokes at the top, giving them subtle vibrations and causing the dried small fish caught between the spokes to fall downward. Therefore, dried small fish clogging between the spokes can be efficiently removed, and unlike flat nets, strong vibrations are not applied and the dried small fish are not damaged. Also, no intense noise is generated.

In addition, according to the second configuration, a plurality of sorting chambers are arranged in parallel, and the feed plate is configured to feed the sorting chambers in order from the one with the smallest spoke interval, so that the dried small fish can be sorted into multiple types at once. can do.

The arrangement pitch of the spokes 5 is set to become larger toward the D side. And the 1st to 4th sorting rooms 4
A plurality of spiral feeding plates 9 are disposed on the inner circumferential surface of the spokes 5 of A to 4D, and both ends thereof are connected and fixed to the guide tubes 7 on both sides of the first sorting chamber 4A and the fourth sorting chamber 4D. 9 to drive the sorting rotor 1.
By rotating in the direction of arrow A, the dried small fish supplied from the dry small fish input port 8 are sequentially sent from the first sorting chamber 4A where the spokes 5 are disposed at a smaller pitch to the fourth sorting chamber 4D, which is larger. The structure is such that the small dried small fish are dropped from between the spokes 5 in order to be sorted. Reference numeral 21 denotes a discharge tube provided on the guide tube 7 on the opposite side of the input port 8 and having a discharge port.

Furthermore, on the inside of the support rod 6 at the outer periphery of the spokes 5 of each sorting chamber 4A to 4D, two vibration rings 10 having a slightly larger diameter than the outer periphery of the spoke 5 are rotatably attached to each of the sorting chambers 4A to 4D. It is fitted externally. The movement of these vibration rings 10 in the axial direction is regulated by a guide 11 provided on the support rod 6, and a weight 10a is attached to one location of the vibration ring 10 to rotate together with the spokes 5. is prevented.

The sorting rotor 1 has each rotor flange 3
is attached to the sorting machine stand 2 through rollers at two places on the bottom side.
One is an idling roller (not shown) and the other is a drive roller 12, and the drive roller 12 is attached to a drive shaft 13. A passive pulley 14 attached to one end of the drive shaft 13 is interlocked and connected via a V-belt 17 to a drive pulley 16 which is rotationally driven by a rotor drive motor 15 whose rotation speed can be adjusted by an inverter system. The sorting rotor 1 can be rotationally driven in the direction of arrow A by the drive motor 15 via the drive roller 12 .

Further, on the outer periphery of the support rod 6 between the rotor flanges 3, each sorting chamber 4 is fixed to the sorting machine stand 2.
A cylindrical casing cover 18 covering A to 4D is provided, and an outlet duct 19 for discharging the selected and dried small fish is opened at the bottom of each casing cover 18. Further, below the exit duct 19, conveyor devices 20 for carrying out the sorted and dried small fish are arranged.

Next, the sorting operation will be explained with reference to FIGS. 2 to 4.

When dried small fish that have undergone pretreatment such as dust removal are supplied to the input port 8, the rotor drive motor 15 is activated, the drive roller 12 is rotated, and the sorting rotor 1 is rotated in the direction of arrow A.

The dried small fish put into the first sorting room 4A are
As shown in the figure, the spokes 5 are sequentially sent from the second sorting chamber 4B to the third sorting chamber 4C and the fourth sorting chamber 4D by the feed plate 9 while jumping on the inner peripheral side, and are sent to each of the sorting chambers 4A to 4D. Dried small fish are dropped from between the five spokes of the machine and sorted.

At this time, the dried small fish sandwiched between the feed plate 9 and the spokes 5 is lifted upward along the rotational direction while riding on the feed plate 9, as shown in FIG. 2A. As shown in Figure 3B, it falls from the feed plate 9 before reaching the top. Then, the fallen dried small fish jumps on the spokes 5 as shown in FIG. be done.

Dried small fish larger than the spacing between the spokes 5 are sent to the next sorting chambers 4B to 4D by the action of the feed plate 9 while repeating the same operation, and the dried small fish are sorted according to the set dimensions in the second sorting chamber 4B and beyond. be exposed. Fourth
Large dried small fish that have not fallen in the sorting chamber 4D are discharged from the discharge port of the discharge tube 21.

By the way, the dried small fish, especially chirimenjiyako, etc., have a complicated curved shape, and there is a big problem that they get caught between the spokes 5 and cause clogging. To prevent this, this sorter uses a vibrating ring. 10 is adopted.

That is, since this vibration ring 10 is provided with a weight 10a at one location, statically the fourth
As shown in FIG. D, the weight 10a is at the lowest point, and the side of the vibration ring 10 opposite to the weight 10a is in contact with the top of the outer peripheral surface of the spoke 5. When the sorting rotor 1 starts rotating in the direction of arrow A,
As shown in the figure, friction occurs between the vibration ring 10 and the spokes 5 at the top contact surface, causing the vibration ring
starts rotating in the same direction of arrow A as the sorting rotor 1 and is rotated by a predetermined amount. At that time, the vibrating ring 10 is separated from the top of the outer periphery of the spoke 5, and when the weight of the weight 10a acts larger than the frictional force between the vibrating ring 10 and the spokes 5, the fourth
As shown in FIG.
The weight 10a slides on the top and moves to the lowest point.
At this time, the vibration ring 10 hits the spokes 5 at the top, giving the spokes 5 subtle vibrations. Due to this vibration, the dried small fish caught between the spokes 5 are released, dropped, and returned to the sorting flow. In this way, the vibrating ring 10 applies subtle vibrations to the top where clogged dried small fish are extremely likely to fall, making it possible to eliminate the clogging without damaging the dried small fish, and making a large impact noise. I don't even give out.

Effects of the invention As described above, according to the first configuration of the invention, by putting dried small fish into the rotating sorting rotor, dried small fish smaller than the spacing between the spokes can be sorted by falling from between the spokes. Dried small fish that are not dropped are only agitated by the sorting rotor, so they are not subject to intense vibrations and are less likely to be damaged. In addition, dried small fish that are clogged between the spokes tend to fall when rotated to the top, so clogging occurs very rarely.

Furthermore, when the sorting rotor rotates, the vibration ring is rotated due to the frictional force between the spokes and the vibration ring, and the lowest weight is lifted. When the weight rises to a predetermined position, a gap is created between the spokes and the top of the vibrating ring, and when the weight of the weight overcomes the frictional force, the vibrating ring reverses and returns to its original position. During this reversal, the vibrating ring hits the spokes at the top, giving them subtle vibrations and causing the dried small fish caught between the spokes to fall downward. Therefore, dried small fish clogging between the spokes can be efficiently removed, and unlike flat nets, strong vibrations are not applied and the dried small fish are not damaged. Also, no intense noise is generated.

In addition, according to the second configuration, a plurality of sorting chambers are arranged in parallel, and the feed plate is configured to send the sorting chambers in order from the one with the smallest spoke interval, so that the dried small fish can be sorted into multiple types at once. can do.
