Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fishing line feeding device such as a squid fishing machine.

[0002]

2. Description of the Related Art In a fishing boat such as a squid fishing boat, a plurality of fishing machines are mounted on each of a port side and a starboard side, and a fishing line is wound around a line feeding drum of each fishing machine. The fishing line has a weight attached to the tip, a pseudo bait attached at a predetermined pitch from the tip, and the fishing line is lowered and wound up by rotation of the drum and fed out.

[0003]

However, in the operation using a plurality of fishing machines, (a) the fishing lines adjacent to each other are prevented from becoming entangled with each other under the influence of the tide, and In order to keep the squid in the vicinity of the fishing boat for a long time, it is necessary to keep several fishing lines in the fish school area at the set depth to maximize the fishing result. these
In order to realize (a) and (b), a constant step (step interval) is always provided between the tips of the fishing lines fed from the adjacent fishing machines, and the above-mentioned distance is set between the sea surface and the set water depth. It is necessary to perform a fishing line feeding operation (step operation) in which a fishing line having a certain level difference is always present.

[0004] However, even if the step of the fishing line fed from the adjacent fishing machine is determined according to the set water depth, and the fishing line is started to be fed from each fishing machine based on this, even during the subsequent operation, There are the following problems.

The step pattern formed by the fishing lines fed from a plurality of fishing machines is set as a plurality of patterns which determine whether or not the fishing lines are at the same level at each of a plurality of positions spaced along the side of the fishing boat. (Fig. 3). This step pattern may be changed from one pattern to another pattern according to the wishes of the boatman during operation, but this setting change can significantly increase the feeding speed of many fishing machines by manual operation of the boatman. This is a correction and is very complicated.

[0006] When the set water depth corresponding to the fish school area is changed based on the detection result of the fish school detector, if the stepping operation of each fishing machine is set to the same level as before, the fishing school area can be moved at a constant feeding cycle of each fishing machine. This results in a time zone in which no line is present, resulting in squid scattering. For this reason, when the set water depth is changed, it is desired to immediately update the step interval of the step operation.

[0007] The feeding speed of each fishing machine is liable to fluctuate, for example, the fishing line of a certain fishing machine is caught by a large number of squids, and the fishing speed of the fishing line decreases due to an increase in load. It is easy for a step to be disturbed between fishing lines of an adjacent fishing machine.

An object of the present invention is to automatically set a step between fishing lines fed from a plurality of fishing machines to a desired value.

[0009]

According to the first aspect of the present invention, when a fishing line is fed from each of a plurality of fishing machines mounted on a fishing boat, the tip of a fishing line fed from an adjacent fishing machine. In a fishing line dispensing apparatus for providing a step between portions, a plurality of step modes in which the step patterns formed by the tips of the fishing lines fed from the plurality of fishing machines are specified are stored in advance, and the fishing machine mounted on the fishing boat is provided. The number of adjacent fishing machines required for each fishing machine to form the step mode from each other from the set water depth that is the maximum lowering depth of the fishing line and an arbitrary step mode selected from a plurality of step modes Calculating the optimum level difference between the fishing lines fed from the fishing line, and controlling each fishing machine to control the fishing line feeding speed of each fishing machine so as to form the optimum level difference.

[0010] According to a second aspect of the present invention, in the first aspect of the present invention, the control device detects the feeding of the fishing line of each fishing machine, and the step between the fishing lines fed from the adjacent fishing machines. Is monitored, and when an error occurs between the step and the optimum step, the line feeding speed of each fishing machine is automatically corrected, and the step error can be corrected.

[0011]

According to the first aspect of the present invention, the following operations are provided. When a desired step mode is selected from the plurality of step modes, the control device calculates an optimum step in the step mode, and automatically controls each fishing machine to form the optimum step. Therefore, even if the step mode is changed during the operation, the step between the fishing lines fed from the plurality of fishing machines can be automatically changed to the optimum step without concern for the line entanglement.

According to the detection result of the fish finder, the set water depth corresponding to the fish school area is, for example, as shown in FIG.
When the water depth is changed from the set water depth to the set water depth 2, the control device calculates an optimum height difference based on the set water depth, and automatically controls each fishing machine to form the optimum height difference. Therefore, the step between the fishing lines fed from a plurality of fishing machines is promptly corrected to the optimum step corresponding to the change in the set water depth, and the line is always present in the new fish school area corresponding to the new set water depth 2. You can maximize the catch.

According to the present invention, the following effects are obtained. The control device monitors a level difference between the fishing lines fed from the adjacent fishing machines, and when an error is generated in the level difference from the optimum level, the fishing line feeding speed of each fishing machine is automatically corrected, and the level error is corrected. Can be modified. Therefore, it is possible to quickly repair the disorder of the step generated between the adjacent fishing machines during operation.

Hereinafter, a step operation procedure of each fishing machine 12 by the centralized control panel 21 and each control panel 22 in the fishing line feeding device 20 will be described. (1) In the fishing line dispensing device 20, a plurality of step modes M1 to M4 (FIG. 3) in which the step patterns formed by the tips of the fishing line 16 fed from each fishing machine 12 are mutually specified are prepared in advance. . The step modes M1 to M4 are input to the control unit 21A from the setting panel 21B of the centralized control panel 21 and are stored in the control unit 21A in advance. Step mode M1
(FIG. 3A) shows that the initial state of the step pattern in the boat length direction (when the fishing line 16 of the fishing machine 12 on the bow side is in the longest feeding state) is linear, and the step coefficient P = 1. . In the step mode M2 (FIG. 3B), the initial state of the step pattern is two linear, and the step coefficient P = 2. In the step mode M3 (FIG. 3C), the initial state of the step pattern is 3

The calculation is performed again and the setting is changed.

(3) The above calculation result of the central control panel 21
The optimum step h of (2) is transferred to the control panel 22 of all the fishing machines 12. The control panel 22 of each fishing machine 12 controls the motor 13 of the fishing machine 12 so that the fishing machine 12 forms its optimum step h with another fishing machine 12 adjacent thereto. The feeding speed of the fishing line 16 is controlled. In the control panel 22 of each fishing machine 12, the amount of fishing line dispensed by the fishing machine 12 is detected by a rotation detecting device (for example, a pulse generator) 17 of the drum 15, and the detection result is transferred to the centralized control panel 21.

In the fishing line dispensing device 20, the above (1)
According to (4), a step operation for giving the optimum step h to the fishing line 16 fed from each fishing machine 12 is performed, and this step operation is repeated as shown in FIGS. 5 (A) to 5 (C). Then, the central control panel 21 monitors the current feeding position (depth position) of the fishing line, which changes moment by moment, of each fishing machine 12, and controls each fishing line so as to maintain the optimum level h between the fishing lines of each fishing machine 12. To control the machine 12.

Incidentally, in the fishing line feeding device 20,
The input of the control data required for the calculation of the optimal step h in (2) may be performed on the setting panel 22B of the control panel 22 of each fishing machine 12 without using the setting panel 21B of the centralized control panel 21. At this time, the control panel 2 of each fishing machine 12
The control data input to the second setting panel 22B is transferred to the central control panel 21 and subjected to arithmetic processing as described in (2) above. According to this, it is possible to change the set water depth during the operation and change the selection of the step mode even at a position remote from the central control panel 21 in the wide hull 11.
