TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an activity device for utilizing fish selected while alive.
[0002]
[Prior art]
FIG. 10 is a diagram schematically illustrating a conventional sorting and activating operation when shipping fish of cultured fish. As shown in this figure, a hopper stand 2, a sorting work table 3, and an activity work table 4 are installed in a row on a fishing boat in order to perform the sorting and active work. The fishing boat stops next to the fish farming cage for the fish to be shipped, and picks up live fish 1 such as yellowtail and amberjack with a large net 5 from the fishing boat and puts it alive on the hopper table. For example, 6 to 7 workers surround the sorting work table and the active work table. The fish 1 is manually sent from the hopper table 2 to the sorting work table 3 one by one, and the weight of the fish is placed on the sorting work table. (Fish weight) is empirically determined by visual inspection, and fish smaller than the prescribed fish weight are returned to the living skull and only large fish are transferred to the work bench.
The active work table 4 “lives” the fish 1 transferred from the sorting work table 3. This activity allows the fish to be kept fresh. Utilized fish are stored in ice tanks provided on fishing boats and returned to fishing ports for shipment. Since the fishing boat is not so large, sorting and utilization work is often performed on the hopper.
[0003]
[Problems to be solved by the invention]
In the conventional utilization work described above, since all the work is performed manually, there are the following problems.
(1) The work is on a rocking fishing boat, so it is hard work. In particular, since the work needs to be completed in a short time, the work is performed at a rapid pitch, which is not only severe but also easily injured.
(2) For example, the operation time of the active operation requires about 5 seconds per one even for a skilled worker. Therefore, a large number of workers are required, and in order to perform a required processing speed of about 1 second / animal, five or more persons are required even for active work alone. In addition, when the worker is immature, it takes more time, and more mistakes and injuries occur.
[0004]
To solve the above-mentioned problem, for example, Japanese Patent Application Laid-Open No. 8-38030 has already been disclosed.
Japanese Patent Application Laid-Open No. 8-38030 discloses a “fish sting machine”, as schematically shown in FIG. 11, a sorting table 2 on which fish is placed, a downwardly inclined delivery gutter 5, a fish detection sensor (not shown), a movable It is provided with holding plates 6a and 6b, a blade 7 and a discharge shutter 8, detects the nose of the fish thrown into the delivery gutter 5 by a fish detection sensor, and holds down the body of the fish by the movable holding plates 6a and 6b. The head is pierced, and the fish is discharged to another adjacent discharge gutter by the discharge shutter 8.
[0005]
However, this fish sting machine had the following problems.
(1) If the adult fish before the activity is good, the adult fish supplied on the sending gutter 5 will lie down and jump and jump, and the fish cannot be stopped at a predetermined position. The fish heads backward, and the head of the fish may become vertical or bent greatly. In this case, once the nose tip of the fish is detected by the sensor, the desired position of the fish cannot be pierced by the blade 8 and the optimum “activity” for keeping the fish fresh cannot be performed.
(2) If the inclination angle of the discharge gutter 5 is made steep (for example, about 25 degrees) so that the fish does not move backward even if the life is good, the whole weight of the fish acts on the nose of the fish after activation, and the nose becomes Even if the catch shutter is caught by the fish detection sensor and the discharge shutter 8 is opened, lateral displacement to another adjacent delivery gutter cannot be performed smoothly. For this reason, it takes time to pay out fish after utilization.
[0006]
The present invention has been made to solve the above problems. That is, the object of the present invention is to (1) use the selected live fish in a short period of time, and (2) return the fish due to bouncing or the like, even if the fish is good or flat. And an accurate positioning without any bending of the head, so that the optimum “activity” can always be achieved, and (3) an activity device that can transfer the activated fish to the next process in a short time.
