Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is for the purpose of boiling small fish,
The present invention relates to a sorting device such as dried sardines that is lightly dried, and particularly to a sorting device used to remove relatively large fish that are mixed in dried shirasu or other dried sardines.

[0002]

2. Description of the Related Art In general, so-called "niboshi," which is produced by boiling and drying small fish such as white-faced shirasu fish, and drying them, the shirasu fish, which is the material itself, has large and small variations. Small fish such as small crab and small shrimp, which are smaller than the body of the white fish, and small fish such as young horse mackerel and young sea bream (hereinafter simply referred to as small fish) are mixed. Since such miscellaneous fish mix lowers the quality of dried sardines as a product, conventionally, the dried sardines were placed on a sieve used as a screening net, which was then vibrated in the direction along the net surface for sifting. It was In other words, while moving the dried sardines left and right on the sorting net, the large dried fish are left to drop the dried sardine that is the product, or conversely, the dried sardine that is the product is left and the fish bodies and scales that have collapsed are removed. Work was being done.

Further, the size of the mesh of the sorting net used therein is about 1.5 to 2 times as long as the length of the dried sardines extracted as a product, in order to prevent large miscellaneous fish from passing through, and the size of the net is relatively fine. I was using a net. Therefore, the screening nets were often clogged, but conversely, if the nets were made larger than this, the inclusion of small fish naturally increased.

[0004]

However, according to the above-mentioned screening method using a sieve, the vibration of the screening net causes the screening net and the fish bodies to rub against each other violently, resulting in scratches or damage to the fish bodies. There was a problem that the quality of the dried sardines was deteriorated because the shape was lost.

Further, as a result of research, the inventors of the present invention have given a comparatively coarse mesh of about half of the average fish length of dried sardines, which is a product, by applying a gentle vibration to the screening net in a direction perpendicular to the mesh surface. I have found that even if you use a sorting net, small fish will not fall through it and will be transported, but on the other hand, if you use such a large sorting net, if the net is loose, it will stay on the net. There was a problem that relatively large fish that should have passed through the mesh, or conversely, the sardines that should be the product were handled as miscellaneous fish due to the jammed fish.

[0006]

In order to solve the above-mentioned problems, the present invention is provided with a strained sorting net which is inclined, and a vibrating means which gently vibrates the sorting net vertically. . In addition, a sorting net is provided between the two rollers in a tensioned manner, and the sorting net is provided while being inclined,
The sorting net is gently vibrated in the vertical direction by vibrating means. Specifically, the two rollers are supported by a support frame, and the support frame adjusts the axial distance between the two rollers. A tensioning device is provided, and the size of the mesh of the selection net is set to 1/3 to 1/2 of the size of small fish to be removed.

[0007]

The boiled and semi-dried dried sardines are transported on the sorting net by the transport means. The dried sardines are supplied in the form of a nodule on the sorting net, but they are gently shaken by the vibrating means to float slightly on the sorting net, and the sorting net moves in the meantime, so the dried sardines are mutually fished. It moves downwards along the inclination of the screening net without rubbing. At this time, when about half of the fish body enters the mesh, the dried sardines having the desired size fall from the mesh by their own weight, and small fish having a size larger than that are transported and eliminated.

[0008]

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. The sorting device 10 includes a frame 11 and upper and lower sorting nets 12a and 1a.
It supports a sorting net 12 composed of 2b and a chute 13. The upper and lower selection nets 12a and 12b have a substantially square mesh formed by the steel wire W and are supported in a tensioned state so as not to be loosened. Reference numeral 14 is a belt conveyor that conveys the dried sardines onto the sorting apparatus 10.

The sizes of the meshes of the upper and lower sorting networks 12a and 12b are set as follows. That is, as shown in FIG. 4, the upper selection net 12a is set to about 1/3 to 2/3 of the average fish length which is preferable for dried sardines.
As a result, the large small fish F are transported without passing through the mesh P, as shown in FIG. As shown in (b) of the figure, when the half-body of the fish enters the mesh P, the dried sardines f of the average size of the product rotate by its own weight and pass through the mesh to the top of the sorting net 12b below. To fall.

The mesh P of the lower sorting net 12b is as fine as the conventional sorting net, and is set to about 1/4 to 1/7 of the average fish length which is preferable as a product. As a result, the collapsed fish body, fish scales, etc. in the previous boil-up process pass through this and fall onto the chute 13 and are removed. The chute 13 is provided to receive scrap fish and debris that have passed through the lower sorting net 12b, and is formed into a gutter shape by welding a thin steel plate. Reference numerals 12c and 12c denote receiving boxes attached to the lower ends of the sorting nets 12 and the chutes 13, respectively, for receiving dried sardines and scraps produced from the dried sardines.

The frame 11 is supported on a support plate 15 via a vibration exciter 16, and is vibrated vertically upwardly and gently by the vibration exciter 16. The degree of gentle vibration is such that the fish body is lifted from the sorting net by about 1 to 2 mm at a cycle of about 60 to 80 times per minute.
If the vibrating force is too strong, large fish tend to pass through the screening net easily. If the vibration cycle is too slow, the efficiency will decrease, and if it is too fast, the contamination rate of large fish will increase and the quality will tend to deteriorate.

2 and 3 show another embodiment in which the operating principle of the above-described embodiment is used as it is to save labor. In this embodiment, the selection device 10 for sardines has a frame 11. The frame 11 differs from the previous embodiment in the vibrator 16
It is directly supported by the support plate 15 without going through. The frame 11 supports two fixed rollers 21 and 22 and one tensioner roller 23. The tensioner roller 23 can be moved in the direction indicated by the arrow in the figure by a well-known tensioning means, whereby the endless sorting net 1 described later is provided.
It is configured so that 2 can be tensioned or relaxed.

In this embodiment, the sorting net 12 is in the form of an endless belt, and the three rollers 21,
It is wound between 22 and 23. One side of the sorting net 12 is arranged at an angle of about 45 °. This sorting net 1
2 is appropriately tensioned by a tensioning means (not shown), and is driven by being switched upward or downward by an electric motor (not shown). Reference numeral 24 denotes a feeding conveyor arranged above the sorting net 12, and the boiled and semi-dried dried sardines are conveyed and continuously supplied onto the sorting net 12.

In this embodiment, the vibrator 16 is provided below the inclined surface of the screening net. That is, the vibrating portion 16a formed in the frame shape is replaced with the driving portion 16 composed of an electromagnetic device.
It is configured to vibrate in the plane direction by b. The drive portion 16b is a commercially available electromagnetic vibration unit itself, and the vibration portion is separately manufactured and attached to the electromagnetic vibration unit afterwards. 17 is a device for removing
When there is dried sardines or scraps adhering to the sorting net 12, the scraps are scraped off, and is composed of a small shaker having the same structure as the shaker.

25 is a sorting device 10 for the dried sardines that have been sorted.
It is a carry-out conveyor for taking out from. The carry-out conveyor 25 is composed of a commercially available belt conveyor, is arranged inside the sorting net 12, and is provided in a direction traversing the net. A hopper 26 is composed of two stainless steel plates arranged on both sides of the carry-out conveyor 25. The hopper 26 receives the product dried from the sorting net 12 above and guides it onto the conveyor belt.

Since the second embodiment is constructed as described above, when the sorting apparatus 10 is operated, the loading conveyor 24, the unloading conveyor 25, and the belt-shaped sorting net 1 are provided.
2 begins to transport dried sardines. At the same time, vibration is applied to the sorting net 12 by the vibrator 16 in the direction perpendicular to the plane.

When the sorting net 12 is vibrated and bulges outward, the dried sardines placed on it are slightly raised. Since the sorting net moves slightly while the fish body floats, the size of the fish caught on the sorting net that is of the desired size is supported when the position supported by the wire forming the sorting net changes slightly. As a result of the change in position
The weight supported by the wire is no longer balanced,
It rotates, passes through the mesh P, and falls downward.

The dried sardines that have dropped down are carried out by the conveyor 25.
And is conveyed to the receiving box 12c. In addition, relatively large fish remaining on the sorting net 12 gradually move downward due to their own weight,
Similarly, it falls into another receiving box 12c. When the endless sorting net 12 rotates clockwise in FIG. 2, the other receiving box 12c is provided on the tensioner roller 23 side.

[0019]

As described above, according to the present invention, when the fish are sorted, the sorting net is moved with the fish floating, so that the sorting net can be moved along the mesh surface like a conventional sorter such as a sieve. Since the fish bodies do not rub against each other when the sorting net vibrates like the one that vibrates in the direction, there is an effect that the fish bodies are less damaged and efficient sorting is possible.
