Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic squid fishing device that is capable of centrally controlling a plurality of automatic squid fishing machines that automatically carry out squid fishing operations using an electric hoist.

Modern automatic squid fishing equipment installed on fishing boats consists of multiple automatic squid fishing machines placed along the sides at predetermined intervals. Each automatic squid fishing machine has a winding drum attached to a rotating shaft and an electric motor for rotating the winding drum in the winding direction and the winding down direction at a predetermined speed, and has nine winding drums. It is designed to catch fish by manipulating a set fishing line.

The control modes of this automatic squid fishing machine include a simultaneous mode in which all fishing lines are hoisted and lowered at the same timing, and a sequential mode in which the timing of hoisting and lowering is different for each machine. , and are selected by commands from the central control unit according to operating conditions such as the speed of tidal currents.

In addition, during the process of pulling up the fishing line, there is a ``shakuri movement'' that is unique to squid fishing, in which the fishing line is pulled up an appropriate length, stopped at that position for a short period of time, and then pulled up again an appropriate length. be exposed. Selection of these control modes and jerking operations is performed in response to commands from a central control section provided on the bridge or the like.

However, in conventional automatic squid fishing equipment, operating conditions such as fishing line winding and lowering speeds, water depth, and shackle operation mode are individually set for each automatic squid fishing machine and specified according to commands from a central control unit. configured to perform an action. Therefore, when changing from simultaneous mode to sequential mode or vice versa, or when it becomes necessary to change the shakuri operation mode, the settings of all automatic squid fishing machines must be changed individually, and the operating conditions must be changed. It is difficult to respond to frequent or rapid changes in

This invention was made in order to eliminate the drawbacks of automatic squid fishing devices as described above, and it is possible to control all the operation modes of each automatic squid fishing device by commands from a central control unit, and also to To provide an automatic squid fishing device capable of accurately responding to all operating conditions by dividing the device into a plurality of groups and configuring each group to be given an arbitrary operation mode.

These keys 63-1 to 63-5 can be pressed after pressing key 57c during the above-mentioned jerk movement operation.
Can also be used to specify any group or total loss.

The simultaneous mode will now be explained.

While all the automatic squid fishing machines 2-1 to 2-16 are waiting at a water depth of Om, the central control unit 4 simultaneously commands all the automatic squid fishing machines 2-1 to 2-16 to lower the line. give. As a result, each automatic squid fishing machine 2-l to 2-16
The winding is carried out at a preset speed at a predetermined water depth, and then the winding is carried out.
30 rotations are sequentially transmitted to the central control unit 4 via the cable 5. The centralized control unit 4 controls each automatic squid fishing machine 2-1 to 2-2.
From the data on the winding drum rotation speed sent from the winding drum 23, it is detected that winding is delayed, and the rotational speed of the winding drum 23 is adjusted to the delayed automatic squid fishing machine until the delay is recovered. Send a command to speed up. As a result, all the automatic squid fishing machines 2-1 to 2-16 wind up at the same speed, and all the fishing lines are wound up at the same time to the water depth am. This means maximizing the benefits of the simultaneous mode, which aims to prevent line entanglement due to different fishing line depths during winding.
Furthermore, since all the fishing lines are wound up at the same time to the water depth Om, it is possible to immediately start lowering the next fishing line, eliminating the need for waiting time until the last fishing line is wound up at the water depth Omt.

In order to obtain this operation, the centralized control unit 4 sends a signal indicating the rotation direction and rotation speed of each winding drum 23 from the time when the lowering command is issued to each automatic squid fishing machine 2-1 to 2-16. Based on this input signal, a signal necessary to increase the rotational speed of the winding drum is sent to the automatic squid fishing machine whose lowering and winding are delayed.

Next, the order of general squid fishing work will be explained with reference to FIG. FIG. 4(a) shows a state in which the weight 11 is directly below the water surface, and this state corresponds to the water depth Om. Next, when the winding drum 3 is rotated in the downward direction, the fishing line 12 is lowered and the weight 11 is lowered as shown in FIG. The take-up drum 3 stops (FIG. 4(C)). After stopping for a short time (for example, 1.5 seconds) in this state, reeling is started, but during the reeling section from the lower limit of water depth to the predetermined reeling depth, the reeling action intermittently winds up the fishing line to encourage squid to bite. After reaching the prohibited depth, it is hoisted at a constant speed (Fig. 4 (d)), and then hoisted at a constant speed to the water depth Om (Fig. 4 (e)). Wait for the next lowering command. The fishing operation is carried out by repeating this operation, and in the brake fishing device of the present invention, this series of operations is carried out according to instructions from a microcomputer.

Further, the jerking operation in the jerking section may be performed according to a jerking operation mode preset in the memory of the central control unit 4, or according to the jerking operation mode individually set for each automatic squid fishing machine. According to this invention, in either case,
It is possible to call up the automatic squid fishing machine with the best fishing results using the centralized control unit 4, and transfer the jerking operation mode adopted in this automatic squid fishing machine to any other or all automatic squid fishing machines. be. Movement of this jerk operation mode can be performed for any one machine or for a total loss by operating the "shake move" key 57 as described above, or for any group selected with the keys 63-1 to 63-4. It can be done instantly.

In this state, if the "single" key 51 is pressed, the total loss performs a predetermined squid fishing operation independently of other machines based on the data set for each machine. Further, if the "simultaneous" key 52 is pressed, each automatic squid fishing machine 2-1 to 2-16 operates in the above-mentioned simultaneous mode for squid fishing for each group specified by the switches 62-1 to 62-16. I do.

In the above embodiment, four pushbutton switches were used as means for specifying the group of each automatic squid fishing machine, but for example, the key 61a corresponding to the number of each automatic squid fishing machine
It is also possible to perform the same operation by pressing one of the keys 63-1 to 63-4 after pressing , and then specifying the group and reading the specified symbol.

As described above, according to the present invention, all the operation modes of a plurality of automatic squid fishing machines can be centrally controlled by commands from the central control unit, and each automatic squid fishing machine can be assigned to one of a plurality of groups. In the simultaneous mode, each group is configured to operate at the same time, so it is possible to operate in the optimal configuration depending on the fishing ground conditions, and it is expected to improve efficiency and increase fishing results.
