Problems solved by technology

This way, the time it takes to sink the sinker to the intended depth becomes an issue
[0010] In addition, in order to change from fixed speed to fixed speed in two stages, there is a problem that it is impossible to finely control the speed change corresponding to the sinker sinking by its own weight.
[0011] Furthermore, in the above-mentioned control method, the numerical values ​​such as the rotating speed V3, V4 and water depth L5 of the drive motor actually use the results set by the intuition and experience of the fisherman. Cause problems such as fishing line prolapse

Embodiment 1

[0141] The settlement test of the sinker is carried out according to the following method.

[0142] The pendant used is cast iron RDM (mass 1125g, volume 155.9cm 3 , Density 7.2g / cm 3 ). The sinker is installed at the front end of the fishing line. The connecting hook for the hook extends over a range of 40m at the tip of the fishing line.

[0143] The speed change of the pendant when it sinks by its own weight is as follows: Figure 9 As shown, the payout length of the fishing line between 0 and 15m is equivalent to the speed increase area X, and the speed of the sinker can reach up to 3.3m / s. Then, when the pay-out length of the fishing line is between 15 and 40m, the speed of the weight decreases from 3.3m / s to 2.4m / s. Finally, between 40 and 100m, it is equivalent to a certain speed zone Z where the speed of the weight converges to a roughly constant value, and the speed of the weight is basically stable at 2.4m / s.

[0144] According to the above results, the Figur...

Embodiment 2

[0147] As Embodiment 2, the weight is controlled according to a control method including speed-up processing. Pendant adopts the same as embodiment 1. After the sinker is thrown into the seawater, the rotational speed of the driving motor is increased, and it is linearly increased to 3.1m / s (=140rpm) at the water depth L0. Then keep 3.1m / s from water depth L0 to water depth L1. Then reduce the speed of the drive motor from 3.1m / s to 2.4m / s (=110rpm) from the water depth L1 to L2, and set the speed of the drive motor to 2.4m / s from the water depth L2 to the water depth L3 . In addition, the water depth L0 is set to 12m in the speed increase area, the water depth L1 is set to 25m after reaching the speed decrease area, and the water depth L2 is set to the hook installation length of 40m.

[0148] Figure 11 It shows the result of controlling the settlement of the sinker according to the above-mentioned control method. Figure 11The command speed given to the drive motor in ...

Abstract

A method and a device for controlling a weight capable of rapidly lowering the weight without producing problems with line slack and others. In the method of controlling the lowering speed of the weight when the weight attached to a fishline is lowered from a sea level to a specified depth, the weight comprises a deceleration means for decelerating the lowering speed of the weight according to the reduction in speed when the weight is positioned at a depth corresponding to a speed reducing area when a change in the speed of the weight when the weight is lowered by its own weight is classifiedinto a speed increasing area where the weight is thrown into the sea level, accelerated, and reaches the maximum speed, the speed reducing area where the speed of the weight is changed to be reduced after the speed increasing area, and a constant speed area where the speed of the weight is converged to an approximately specified value after the speed reducing area.

Description

[0001] technology proximity [0002] The present invention relates to a control method and a device for a sinker, and more specifically, relates to a control method and a control device for a sinker used for squid fishing to sink a sinker. Background technique [0003] When catching squid, the fishing money with pendant attached to the front end of the connecting hook is wound on the drum, and the main body of the squid fishing machine is rolled down and rolled up along the drum to catch squid. The number of cycles of reeling and reeling of the squid fishing machine has a great impact on the catch. Simply put, the more cycles, the higher the probability of squid taking the bait. Therefore, fishery personnel hope to increase the number of cycles even if only one operation is performed. Generally speaking, each squid fishing machine performs about 200 to 300 cycles a day. [0004] A driving motor is provided in the control device of the pendant, and a pair of rotating drums are...
