Description

The present invention relates to an apparatus for collecting food parts of giant jellyfish that are edible, such as Echizen jellyfish.

Conventionally, damage caused by jellyfish of a relatively small size (with an umbrella diameter of about 15 centimeters) such as water jellyfish in the sea near Japan, for example, jellyfish generated in large quantities near water intakes in facilities such as power plants Many developments and proposals have been made regarding methods and devices for preventing damages such as the situation where machinery must be stopped after entering the factory. For example, there are many disclosures in patent publications, patent publications, and the like under the names of jellyfish exclusion devices, intrusion prevention devices, removal devices, and processing devices.
Published Patent Publication, JP2001-140245, Jellyfish Recovery Device Published Patent Publication, JP-A-2002-138446, Jellyfish Collection and Reuse Method Published patent publication, JP-A-2004-122118, jellyfish processing apparatus and jellyfish processing method

  However, in recent years, large numbers of giant jellyfish, such as Echizen jellyfish, have been generated and have entered large amounts in stationary nets and bottom nets, blocking the meshes, making them unusable or impossible to lift, or damaging fish that have been caught, This has caused serious damage to the fishery by significantly reducing the freshness of the fishery. It is difficult to apply the methods and devices disclosed in the publications to the fishery damage caused by such giant jellyfish. In addition, no effective method or device has been developed so far to relieve and resolve the damage to the fishery caused by giant jellyfish. An effective solution to this problem and the rapid development of equipment are awaited.

  On the other hand, Echizen jellyfish, bizen jellyfish, and the like have been used effectively as food materials. However, since an effective method and apparatus for efficiently capturing giant jellyfish such as Echizen jellyfish for food use has not been developed, the amount of giant jellyfish used effectively has been small. For example, as a conventional method of catching giant jellyfish, for example, two to three people are boarded on a 5 ton boat and scooped with a tamo net with a diameter of about 1 m, or 15 to 20 nets with a height of 5 to 8 m and a width of about 40 m. The hanged net method was used, where the jellyfish were caught at a right angle to the tide and caught over the net.

  As described above, in the conventional method of capturing a giant jellyfish, the captured giant jellyfish has to be transported to the port as it is to be landed and processed. However, many giant jellyfish have a diameter of 1 to 2 m and a weight of 150 kg or more, and landing work and other processing work have been difficult. Furthermore, the non-food parts other than the umbrella are easily rotted, and there are toxic parts such as tentacles, making it difficult to secure a disposal place and a disposal process.

The present applicant has made an invention that solves the above problems and has applied for a patent (Patent Document 4). However, in the above-mentioned invention, in order to capture the giant jellyfish, first, the giant jellyfish swimming in the sea is brought to the surface of the sea, and the giant jellyfish that has emerged is captured. The giant jellyfish levitation means consists of a gathering net for gathering the giant jellyfish at an appropriate location and a bubble release pipe for levitating the giant jellyfish swimming in the sea, and the gathering net is forward from the front end of the hull frame. It is composed of two vertically sloping nets that open toward. The lower position of the net is preferably several meters (for example, 2 to 5 meters), and the length of each net is preferably several meters. Further, the depth position of the bubble discharge pipe is preferably the same as the lower position (depth) of the net, or preferably 0 to 1 meter deeper from the lower position.

The giant jellyfish capturing means is composed of an adsorption device, and the adsorption surface of the adsorption device is configured to be movable in the front-rear direction, the left-right direction, and the up-down direction so that the surface of the giant jellyfish umbrella can be adsorbed. ing. The movement in the front-rear direction is carried by the slider sliding on the guide rail, and the support shaft of the suction device is held by the slider so that it can rotate and move up and down. It is configured to be possible.
Japanese Patent Application No. 2006-183811

The above-mentioned invention of the application described above is intended for capturing giant jellyfish swimming within a depth of several meters from the sea surface. However, giant jellyfish such as Echizen jellyfish are swimming at such depths for a period of time during the day, and other times are usually swimming at a depth of 10 to 30 m. There is a problem that the number of giant jellyfish that can be captured is limited to a small number. In addition, bubbles are released from pipes in the sea in order to make giant jellyfish float, but since seawater flows at a fairly high speed, a large amount of bubbles must be released, which is a low efficiency as a means of ascent. Is a challenge. Furthermore, even if a giant jellyfish is levitated, there is a problem that the position where it rises cannot be controlled, and when the suction device is operated manually, it is difficult to operate and it is difficult to catch the giant jellyfish umbrella well. . In recent years, the use of giant jellyfish such as Echizen jellyfish as food, use as pharmaceuticals and cosmetics, and other fields has been studied, and a large amount of demand is expected to occur in the near future.

FIG. 7 shows an embodiment of a separating and cutting apparatus using a rotary blade. (A) is a plan view and (B) is a side view. Two driven gears 40a and 40b are provided with rotary blades 41a and 41b eccentrically, respectively. The rotary blades 41a and 41b rotate in directions opposite to each other, and a part thereof overlaps as shown by the circle of the locus of the maximum radius of each blade. The gear 40a meshes directly with the drive gear 42, the gear 40b meshes with the drive gear 42 via the idle gear 43, and the driven gears 40a and 40b have the same rotational speed, but the rotational direction is reversed. Yes. Thereby, the giant jellyfish 10 is cut at the position of the dotted line in the figure, and the food part 10a and the non-food part 10b are separated.

FIG. 8 shows an embodiment of an apparatus for separating and cutting by reciprocating the blade. One end of the cutting blade 45 reciprocates by the slider mechanism 46, and the other end reciprocates up and down while swinging left and right by the link mechanism 47. When moving upward, the cutting blade 45 approaches the giant jellyfish 10 as indicated by the dotted line in the figure, and when moving downward, the cutting blade 45 is further away from the giant jellyfish 10 as indicated by the solid line in the figure. . Therefore, when moving upward, it cuts well. The present invention may use the cutting device shown in FIG. 7 or the cutting device shown in FIG.

Hereinafter, a method for capturing and fixing the giant jellyfish 10 using the three-dimensional moving means 16 and the capturing device 13 and a method (procedure) for cutting will be described. First, the center position of the umbrella of the giant jellyfish is obtained from a photographed image of the giant jellyfish 10 that has floated near the sea surface by the camera 25 provided in the capturing device 13 by an arithmetic unit (not shown). Next, a direction and a distance from the position of the camera 25 to the center position of the umbrella are calculated, and control signals for the motors M1 and M2 are obtained based on the calculated values to drive the motors M1 and M2. When the camera 25 comes right above the center of the umbrella of the giant jellyfish 10, the valve 28a (see FIG. 5) is opened and the capturing device 13 is lowered. When a giant jellyfish is adsorbed on the adsorption capturing unit 21, the suction pressure is rapidly reduced. Immediately after this, when the valve 28b is opened, the giant jellyfish 10 is adsorbed and fixed to the capture device 13 with the umbrella opened. In the state of being adsorbed and fixed, the cutting device 17 cuts and separates the food part 10a and the non-food part 10b. The food part 10a is carried to the opening while being adsorbed, and the adsorbing state is released on the opening and stored in the storage case 18.
