Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to a sorting apparatus for removing minor fish such as banded fish and stingfish that are mixed in Shirasu fish during the production of dried Shirasu. The present invention relates to an improvement of a carrier device.

[0002]

2. Description of the Related Art Shirasu dried, which is generally a kind of dried sardines, is a food prepared by boiling Shirasu fish, drying it in the sun, and slightly drying it. Originally, the material for dried shirasu is shirasu fish, but depending on the fishing ground, shirasu fish is used to catch shirasu fish.
In addition, large fish, such as sardine fish, which is larger than shirasu fish, may be mixed in as miscellaneous fish, and in particular, the mixing of banded fish makes the dried shirasu taste watery and deteriorates its quality. Therefore, generally, immediately after landing, it is visually selected and eliminated. In addition, in order to improve the efficiency of selection, since the small fish have a property of bending when boiled, the white fish is boiled with mixed fish to make a white fish material, and then the wire is arranged in the shape of a sludge. It was proposed by the applicant to pass through and hook the wire to remove small fish. (For example, Japanese Patent Application No. 7-246
No. 94).

[0003]

In order to remove the small fish caught on the wire, the rotating brush is moved along the wire to remove the small fish, but it is not always complete. Cannot be removed,
Occasionally, there was a problem that the product dropped on dried whitebait.

[0004]

In order to solve the above problems, the present invention comprises at least a small fish removing conveyor arranged on the upper side and a product carrying conveyor arranged on the lower side, and the small fish removing conveyors are arranged in parallel. It has a conveyor belt wound between rollers, and the conveyor belt can rotate between the endless links arranged on both sides, the small fish removing plate having a plurality of thin rods juxtaposed to them. And a blocking member for blocking the small fish removing plate from rotating inward.

Specifically, the small fish removing plate is supported by a connecting shaft bridged between endless links arranged on both sides. Further, the blocking member is formed of a part of the endless link, or a support shaft bridged between the endless links arranged on both sides. Further, a rotary brush for scraping off the small fish is provided at the end of the small fish removing conveyor.

[0006]

The small fish removing conveyor arranged on the upper side is composed of a small fish removing plate whose upper surface of the conveyor belt is prevented from rotating by the blocking member. In this state, when the Shirasu fish material that is the fish to be selected is sowed on the small fish removing plate,
The small fish mixed in there caught on a thin bar and stopped,
Silas fish pass between them and fall onto the product conveyor below. The small fish caught on the thin rods are carried to the downstream end of the conveyor, where they fall downward when the small fish removing plate reverses. When the conveyor belt reaches the bottom,
The small fish removing plate rotates about the connecting shaft, and hangs down with the free end of the thin rod facing down. As a result, the small fish caught on the bar fall along the bar and come off from the small fish removing plate.
The rotating brush also helps this movement of small fish.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, reference numeral 10 is a sorting device such as dried sardines according to the present invention. The sorting apparatus 10 is supported by the frame 11, and has a small fish removing conveyor 25 arranged on the upper side and a product carrying conveyor 40 arranged on the lower side. Reference numeral 12 denotes a wheel, which is attached to the lower surface of the frame 11 so that it can be moved easily. Reference numeral 14 is a loading conveyor which is disposed on the side of the sorting apparatus 10 and which feeds the Shirasu fish material F to the small fish removing conveyor 25.

The loading conveyor 14 has a chassis 16 supported by wheels 15, and a belt frame 17 supported by the chassis 16. A lower roller 18 is supported on the lower end of the belt frame 17, and an upper roller 19 is supported on the upper end thereof, and a conveyor belt 21 made of a wire net or a resin net is wound between them. Reference numerals 19a and 19a denote idle rollers, one pair of which is provided on the forward side of the conveyor belt 21 and one pair of which is provided on the backward side thereof, which are used to bend the upper end portion in the horizontal direction. 23 is an air nozzle,
It is arranged across the conveyor belt 21 between the upper roller 19 and the idle roller 19a. The arrow shown in the air nozzle shows the air blowing direction, and the arrow shown in the feeding conveyor 14 shows the traveling direction of the conveyor belt 21.

Thus, when the feeding conveyor 14 is operated and the shirasu fish material F is placed on the conveyor belt 21, the shirasu fish material F is transferred upward by the belt 21, and a part of the shirasu fish material F is transferred to the air nozzle 23. The air blown off from the small fish removes it onto the small fish removing conveyor 25, or the remainder is conveyed by the conveyor belt 21 onto the small fish removing conveyor 25. Reference numeral 24 is a guide net provided over the small fish removing conveyer 25 so as to guide the Shirasu fish material F blown off by the air nozzle 23 so as not to fall outside the small fish removing conveyer 25.

The small fish removing conveyor 25 has an inclined frame 26, one end of which is the frame 11.
Is rotatably supported by a bolt Bt1 on the upper end of the vertical rod 22 and the other end is attached by bolts Bt2, Bt3 via a vertical rod 22, and the inclination of the vertical rod 22 through which the Bt3 is inserted is selected. You can adjust the angle. as a result,
The size of the vertical projection mesh of the small fish removing plate 32, which will be described later, can be adjusted. An upper roller 27 is rotatably supported at an upper end portion and a lower roller 28 is rotatably supported at a lower end portion of the inclined frame 26, and a conveyor belt 29 is wound between them. Reference numeral 30 denotes a rotating brush, which is juxtaposed adjacent to the lower roller 28 for removing small fish. Reference numeral 38 is a receiving box for receiving small fish.

Conveyor belt 2 of the small fish removing conveyor 25
As shown in FIGS. 2 and 3, the reference numeral 9 includes an endless chain 31 arranged on both sides of the inclined frame 26, and a fish removing plate 32 supported between the endless chains 31, 31. In the endless chain 31, links 31a are connected by pins 31b, and a chain roller 31c is supported between them. Also, the pin 3
Every other one 1b is a long one that connects between the endless chains 31, 31 on both sides, one of which is a spindle 33 that rotatably supports the small fish removing plate 32, and the other one. One is configured as a blocking member 34 that supports the small fish removing plate 32 so as not to rotate around the support shaft 33. In other words, the support shaft 33 and the blocking member 34 are supported by the link 31a of the endless chain 31. Reference numeral 26a denotes a triangular protrusion projectingly provided on the upper surface of the inclined frame 26, which gently rises at an angle of about 30 ° with respect to the traveling direction of the conveyor belt 29, and its end is substantially a right angle. Thus, when the conveyor belt 29 advances, the chain roller 31c ascends and descends on the protrusions 35, which causes the conveyor belt 29 to vibrate up and down, shaking and dropping the white fish caught on the small fish removing plate 32. .

The small fish removing plate 32 is a cylindrical base cylinder 32a rotatably fitted and supported on the connecting shaft 33, and the base cylinder 3 thereof.
It is composed of a plurality of thin rods 32b, 32b protruding from 2a in a predetermined direction. In this embodiment, the rod 32b is made of stainless steel having a diameter of 2 mm and is welded to the base cylinder 32a with a gap of about 30 mm, which is slightly wider than the selected white fish. The length of the rod member 32b is the same as that of the base cylinder 32a of the small fish removing plate 32 whose tip ends adjoin.
The length is set to reach the vicinity of. Thus, the small fish removing plate 32 is rotatably supported on the connecting shaft 33, and is supported by the blocking member 34 so as not to hang downward at the free end of the bar 32b when the conveyor belt 29 is on the upper side. It Further, when the conveyor belt 29 reaches the lower side, as shown in FIG. 1, the portion of the bar 32b hangs downward due to gravity. The blocking member 34 does not necessarily have to be provided on both sides of the endless chains 31, 31 as in this embodiment.
It is not necessary to form a rod shape for connecting the two, but the outer rod member 3
Lightly bend 2b outward and directly connect the endless chain 3

It should be noted that the small fish removing plate 32 is not limited to the above-described sludge structure due to the configuration of the present invention, and may of course have a mesh structure in which the rods 32 are provided vertically and horizontally as shown in FIG. The former is slightly inferior in the removal performance of small fish ", it is easy to remove the small fish, and the latter is slightly inferior in the removal of small fish" and is excellent in the removal performance of small fish.

The product transfer conveyor 40 is located below the small fish removal conveyor 25 and is attached to the frame 11. That is, the second tilt frame 41 attached to the frame 11 in parallel with the tilt frame 26.
And an upper roller 42, a lower roller 43 supported on the upper end portion thereof, and a second conveyor belt 44 wound between them, but the conveyor itself has no significant feature. Reference numeral 45 is a product receiving box provided below the upper roller 42. Thus, the product conveyor 40 is sprayed by the air nozzles 23 onto the small fish removing plate 32, receives the shirasu dried S that passes through and drops upward, and transfers it to the product receiving box 45 as indicated by the arrow. Let

As described above, according to this embodiment, the Shirasu fish material F is scattered and seeded on the small fish removing conveyor 25 by the air nozzle 23 from the feeding conveyor 14 over a relatively wide range. Since the product of the Shirasu fish material F, the Shirasu fish that is a product, is relatively thin and straight, it passes between the rod members 32b that form the small fish removing plate 32 and the product conveyor 4 below.
0, and is transported to and collected in the product receiving box 45. On the other hand, the small fish contained in the Shirasu fish material F are
It has a round and round shape when boiled, and because it is thicker than the white fish, it catches on the rod 32b or between two adjacent rods 32b.
Stop on top of two.

Small fish removing plate 3 forming a small fish removing conveyor 25
When 2 moves downward, when passing the side of the lower roller 28 in the vicinity of its lower end, the small fish rubbed by the rotating brush 30 and carried by the small fish removing plate 32 are scraped off. Further, when the small fish removing plate 32 passes through the lower roller 28, the rod 32b of the small fish removing plate 32 hangs downward due to gravity. Therefore, even if there is a small fish caught on the bar 32b, it will slide down into the lower receiving box 38.

[0016]

As described above, according to the present invention, the small fish removed from the Shirasu fish material F by the small fish removing plate 32 are hung down vertically as the conveyor belt 29 advances. Since it falls by its own weight and separates from the small fish removing conveyor 25, small fish can be easily removed from the small fish removing plate 32.
