Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for sorting caught fish by size, and in particular, it uses dynamic friction to sort fish into sardines, whitebait, sand eel, and shrimp for boiling. This invention relates to a rotary fish sorting device that sorts small fish such as saury, horse mackerel, and mackerel by size.

[Prior Art] Fish caught with nets include a mixture of large and small fish. Whether this fish is used for fresh fish or for processing, large added value can be generated by sorting it according to a certain size.

However, at present, there is no practical equipment for efficiently sorting fish by size, and the reality is that fish are almost always sorted manually. Therefore, this sorting process requires considerable effort, time, and effort, and this process has the drawback of significantly reducing freshness.

By the way, as a fish body sorting device, a device has been proposed in which endless belts are arranged in a grid pattern and fish bodies are sorted into large and small sizes between the belts (Japanese Utility Model Publication No. 78698/1983). Also,
A device has also been proposed in which an endless belt is moved between grids and fruits are sorted between the grid and the belt (Special Publication No. 1973-
Publication No. 35093).

Furthermore, a device has also been developed in which a plurality of rollers rotating around a shaft are arranged so that the distance between them becomes wider in the direction of fish movement, and unsorted fish are fed onto the rollers (
Japanese Patent Publication No. 41-15919 and Japanese Patent Publication No. 53-22
Publication No. 097).

[Conventional problems] However, in a sorting device using a belt, the heddle does not have the effect of aligning elongated fish bodies in the transport direction, and the fish bodies fed across the belt are aligned parallel to the heddle and sorted by size. There was a drawback that I couldn't do it.

The total length of fish bodies is many times longer than their thickness (t'^), and unless they are lined up parallel to the belt, they cannot be sorted into sizes without error.

In a sorting device where the fed fish cannot be aligned parallel to the belt, the fish fed across the belt may remain on the belt and be transferred to the delivery side without being sorted, passing between the belts and falling into sorting. Not done.

Therefore, in a size sorting device for elongated objects such as fish bodies, it is particularly important to align the fish bodies parallel to the belt.

A sorting device with multiple rollers connected in parallel has the effect of aligning fish lengthwise with rotating rollers. However, this sorting device requires a drive mechanism to rotate all the rollers arranged in a grid.
Since this drive mechanism cannot be made small and simple, it is difficult to narrow the distance between the roller axes, and furthermore, the roller drive mechanism has the disadvantage of being complicated. For this reason, there was a drawback that the entire device became large. In particular, in a device for sorting small fish such as sardines, whitebait, and horse mackerel, the spacing between the sorting members becomes narrower, but if the distance between the axes of the sorting members is narrowed, they cannot be driven, so it is extremely difficult to downsize the whole device. Ta.

Furthermore, in a sorting device in which the size of fish to be sorted can be adjusted, the distance between the rollers is adjusted during use, but the driving mechanism for the rollers whose distance is changed becomes significantly complicated.

The present invention was developed to eliminate these drawbacks of conventional sorting devices and to provide even more superior features.An important object of the present invention is that the sorting member can be driven by a simple driving means, and the entire To provide a rotary sorting device whose shape can be reduced.

Another important object of the present invention is to provide a sorting device that can be driven by a simple drive mechanism when adjusting the gap between the sorting members.

[Means for Solving Conventional Problems] A rotary fish sorting device includes a plurality of sorting members, a means for driving the sorting members, and a supply means for supplying non-sorted fish to the sorting members.

The sorting members are arranged obliquely downward in the direction of fish movement, and are formed in an elongated shape with a circular cross section, and are parallel to each other or are arranged at intervals that gradually become wider in the direction of movement of fish. They are arranged and attached to the base.

The driving means rotates the sorting member about its axis so that the sorting member can efficiently sort fish under dynamic friction conditions. This drive means includes a pulley fixed to the sorting member, a drive roll disposed close to the pulley and extending in a direction perpendicular to the sorting member so as to be rotatable, and the drive roll and the drive roll. A pulley and a flexible belt hung on the pulley. Rotation of the drive roll is transmitted to the sorting member via a flexible belt and a pulley.

The supply means supplies non-sorted fish to the upper part of the obliquely arranged sorting member.

[Operations and Effects] In the rotary fish sorting device of the present invention, a plurality of sorting members each having a circular cross-sectional shape and arranged downwardly are arranged parallel to each other or in such a manner that the intervals become wider in the direction of movement of the fish. The sorting member is rotated about the axis of the sorting member by a driving member. For this reason, the fish fed onto the sorting member are subjected to an alignment force in the direction perpendicular to the sorting member while sliding down due to the lateral movement of the surface of the sorting member, and this lateral force causes the fish bodies to be aligned with the sorting member. aligned in parallel.

The reason why the fish are aligned by the horizontal reciprocating movement of the upper surface of the sorting member is that fish that are moved laterally by the sorting member do not contact the sorting member uniformly over the entire surface, and the contact state varies locally, and the fish's head Because the weight is different between the fish's tail and the fish's part, the force to turn the fish sideways is different. Some parts are aligned by receiving a weak lateral force. Therefore, as the fish bodies are fed to the sorting member without direction, as they are moved along the sorting member, they are aligned in the direction that is easiest to pass between the sorting members, and moreover, are ideal for sorting. Fall down and be sorted by size. Therefore, it is possible to reduce the number of small fish bodies that can pass between the sorting members when aligned and are sent out between the sorting members without falling while crossing the sorting members, regardless of the fish supply status. This simplifies the supply of fish and allows the fish to be accurately sorted into sizes.

Furthermore, a noteworthy feature of the present invention is that the means for driving the rotating rollers is simple and the entire apparatus can be made extremely compact. In particular, it is possible to realize the feature that the sorting device for small fish such as mackerel and horse mackerel can be significantly downsized.

This feature is achieved through a unique configuration in which a drive roll is placed near the pulley of the sorting member and intersects with the sorting member, and the rotation of this drive roll is transmitted to the sorting member via a flexible belt. be done.

That is, the drive means with this structure can drive a large number of sorting members with a single drive roll, and does not require a large number of drive pulleys or drive gears to drive each sorting member separately.
Sorting members arranged in close proximity can be driven. For this reason, the small fish sorting device has thin pulleys placed close together, making it possible to put into practical use a compact device with a large sorting ability.

Furthermore, since the drive roll and the pulley of the sorting member are connected by a flexible belt, the structure of the drive means is extremely simple.
Moreover, high accuracy is not required in the relative position of the drive roll and pulley, and the drive means can be significantly simplified.

Furthermore, the sorting device of the present invention adjusts the gap between the sorting members to perform sorting suitable for each of small fish and large fish, that is, when increasing the gap between the sorting members when sorting large fish, Even if the relative positional relationship between the drive roll and the sorting member pulley changes, there is no need for any adjustment operations; the belt automatically slips and is automatically adjusted to the optimal position, that is, the shortest position. be. Therefore, it is easy to use without requiring the trouble of rehanging the belt every time the gap between the sorting members is adjusted.

[Preferred embodiment] Embodiments of the present invention will be described below based on the drawings.

The fish sorting device shown in FIG. 1 is installed obliquely downward in the direction of fish transfer (towards the right in FIG. 1) so that the supplied fish are transferred while sliding down. is formed into an elongated rod shape, and as shown in FIGS. 2 and 4, a plurality of sorting members 1 are arranged in parallel or substantially parallel, and a driving means for rotating the sorting members 1; A supply means 2 for supplying non-sorted fish along with water is provided at one end of the upper part of the sorting member 1.

As shown in FIGS. 3 and 4, the sorting member l is rotatably attached to the base 5 through bearings 3.4 at both ends, and is made of, for example, SUS with a polished surface. It is a thin-walled vibrator.

The smaller the outer diameter of the sorting member l, the greater the throughput per area of the sorting device. However, if it is long and thin, it will bend. Therefore, in the case of small fish such as sardines, for example, the outer diameter is 2.
It is formed with a total length of 0mn+φ and a total length of about 2m.

A pulley 6 is fixed to one end of the sorting member l, as shown in FIGS. 4 to 7, so that the sorting member l can be rotated.
A drive roll 7 is supported near each pulley 6, perpendicular to the sorting member 1 and parallel to the plane containing the sorting member, and a flexible lobe 8 such as a polyurethane rope is attached to the drive roll 7 and each pulley 6. The sorting members 1 are rotated in the same direction by the drive roll 7. In this case, Figures 6 and 7
As shown in the figure, the flexible lobe 8
This can prevent slippage between the pulley 6 and the pulley 6.

In addition, as shown in FIG. 8, in the case where flexible lobes 8 are hung on a cylindrical drive roll 7, the tension of each flexible row 18 is automatically adjusted as the drive roll 7 rotates. Therefore, the length of each flexible lobe 8 can be easily adjusted, and slippage can be reduced.

By the way, in the fish sorting device of the present invention, the fish are sorted by size by falling from between the sorting members 1 while sliding them down, but if the sorting part t1 is completely parallel, the sorting members 1 In the meantime, a fish whose thickness is almost equal to the separation between the sorting members may become stuck in the cheek, that is, hanged, and cannot fall. In order to avoid this, as shown in Figure 2, the intervals between the sorting members 10 are made somewhat wider in the direction of movement of the fish, and the fish whose cheeks are stung are moved in the direction of movement, gradually increasing the interval between them. It is only necessary to drop it from the sorting member 1 where the area becomes wider.

In FIG. 9, an alignment arm 21 made of flexible rubber or the like that rotates in a plane parallel to the sorting member 1 is arranged above the sorting member 1, and the fish are placed in the sorting member 1 with this alignment arm 21. This prevents fish arranged in parallel and smaller than the interval between the sorting members, that is, fish that would have to fall between the sorting members l, from passing through without falling from the sorting members, and also prevents fish with cheeks stuck. Also let it fall.

As shown in FIGS. 1 and 10, the sorting unit 22
When connecting the sorting members in multiple stages, the upper stage has the sorting members with wider intervals, the lower stage has the sorting members with narrower intervals, and the sorting members 1 are arranged between each sorting unit 22. Inner chute 23 with a downward slope to catch and catch falling fish
It is preferable to arrange this and use this inner chute 23 to supply the fish falling from the upper stage to the sorting unit 22 on the lower stage.

This is because, according to this structure, the interval between the uppermost sorting members l can be maximized, so the uppermost sorting unit 2
2 can have the maximum processing capacity, and the unsorted fish whose quantity is reduced by sorting large fish here can be sorted by the lower sorting unit with small sorting capacity, so the upper sorting unit 22 The widths, ie, the total areas, of the lower sorting unit 22 and the lower sorting unit 22 can be made almost equal.

The inner chute 23 shown in FIG. 11 is connected to a trap-like water reservoir 27 at the end, and the fish that have slipped along the inner chute 23 once fall into this water reservoir 27 and are then sent to the lower sorting unit along with water. Supplied. This structure has the effect of reducing damage to fish.

In FIG. 12, fish that have slipped down into the inner chute 23 are transferred to a desired location using a transfer pipe 31 using water as a transport medium. The inner chute 23 is provided with a receiving chamber for fish and water at the lower part, and a water supply port 28 is opened on one side of the receiving chamber for supplying water here and allowing the fish to flow out.
The discharge side of the return water pump 29 is connected, and an outflow port through which fish and water flow out is opened opposite the water supply port 28, and a transfer pipe 31 is connected to this outflow port.

The suction side of the water pump 29 is connected to the drain port of the separator 30 and supplies the water separated by the separator to the water supply port 28 of the inner chute 23 again.

A transfer pipe 31 is communicated with the separator 30.
The water and fish transferred in step 1 are separated by a separator 30.

The supply means 2 shown in FIG. 1 includes a reservoir tank 24 in which fish are stored together with water, and a fish pump 25 that sucks the fish in the reservoir tank 24 together with water and transfers them to the upper part of the sorting member 1. Equipped with.

As shown in Fig. 1, the water supplied together with the fish flows down from the sorting member l to the inner chute 23, is again supplied to the sorting member l, flows down to the lower inner chute 23, and finally , the fish and water are separated by a separator 26.
