Description

[Detailed Description of the Invention] The present invention relates to an automatic control circuit for a fishing machine that discharges a predetermined amount of fishing line, performs a groping operation, and automatically winds up the fishing line by sensing the fishing signal.

Recently, modernization and labor-saving efforts have been made in the fishing industry due to the shortage of manpower, and along with this, electric fishing machines are being introduced. By the way, among conventional fishing machines, there are those in which the drum around which the fishing line is wound is simply driven by a motor, and those in which the fishing line can be discharged in an amount commensurate with the water depth or to the depth of the fish school layer. In this case, each time the fishing line is released, it is necessary to determine the release amount commensurate with the water depth or the depth of the fish school layer. The reality is that the fishing rod has to be started and moved by operation, and furthermore, when a fish signal is detected, a switch is operated to drive the motor, thereby reeling in the fishing line, so there is no labor saving. However, it cannot be said that it can promote the development of human resources, and as a result, it has had various problems such as relying on human labor.

The present invention was developed in view of the above circumstances, and includes a transmitter that emits a signal according to the rotation of a line winding drum driven by a motor, and an addition/subtraction system that counts the amount of fishing line released and wound up based on the signal. A memory for appropriately storing this counted value is connected to the counter, and a line remaining setting switch for setting the upper limit of winding and a groping width setting switch for moving the fishing line up and down during fishing are connected to the addition/subtraction counter and memory. A comparator is connected so that the stored value and each set value can be compared with the counted value, and a motor control circuit is connected to the comparator so that the motor is rotated forward, reversed, or stopped when the comparison values match. A fish line microswitch is connected to this motor control circuit in order to operate when a fish line is detected and control the rotation of the motor in the winding direction, thereby releasing a predetermined amount of fishing line and then performing a groping operation. It is an object of the present invention to provide an automatic control circuit for a fishing machine that can automate the process from detecting the presence of a fish to reeling it in.

An embodiment of an automatic control circuit for a fishing machine according to the present invention will be described below.

As shown in FIG. 1, the bobbin winding drum 1 is rotatably driven by a motor M via a transmission mechanism 2 such as a belt. A rotating plate 3 with a part cut out is provided on the rotating shaft of this drum 1.
In this case, a depth detection roller may be provided that rotates when the fishing line wound around the drum 1 is released and wound up, and the rotating plate 3 may be attached to the rotating shaft of this roller. This rotary plate 3 has a rotation speed of the drum,
In other words, it rotates forward according to the amount of fishing line released and the amount of winding up.
Again, the situation is reversed. Transmitters 4 and 5 are provided near the rotary plate 3 and are perpendicular to the plate surface, and the oscillation frequency of the transmitters 4 and 5 is determined by the notch 3a as the rotary plate 3 rotates. A detection element such as a photointerrupter is used for this purpose, but the present invention is not limited to this, and it is also possible to use various detection elements.
An addition/subtraction counter 6 is connected to the transmitters 4, 5;
Addition or subtraction is performed based on the signal time difference between the pulses emitted by the transmitter.When the motor M rotates in the forward direction when releasing the fishing line, the transmitter 4 emits a pulse earlier than the transmitter 5, so addition is performed, and conversely, the transmitter 5 Since it emits a pulse earlier than the oscillator 4, subtraction is performed. The addition/subtraction counter 6 is configured to convert into a numerical value in units of 1 meter depending on the circumference of the drum, etc. For example, if the circumference of the drum, etc. is 1/2 meter, the addition/subtraction counter 6 is configured to convert into a numerical value in units of 1 meter. If it is 1/3 meter, use a ternary conversion counter. The counted value of this counter 6 is readably introduced into a display 7, and when a memory switch 8 is closed, it is supplied to a memory 9 for storage and is also sent to a comparator 10. This comparator 10 includes a line remaining setting switch 11 that sets the upper limit for winding up so that the so-called hook portion on which the fishing hook is attached does not get caught in the drum 1, and a so-called search width for moving the hook up and down during fishing. A search width setting switch 12 is connected, and the value stored in the memory 9 is sent to this comparator 10. This comparator 10 compares the counted value of the addition/subtraction counter 6 with the stored value of the memory 9, the set value of the thread stiffness setting switch 11, and the set value of the searching width setting switch 12, and when they match, It emits a match signal. The motor control circuit 13, which controls a motor forward/reverse rotation stop operation circuit (to be described later) through this coincident rotation, includes a manual switch 14 for manually winding up, discharging, and stopping the fishing line, and an auto switch 15 for automating these fishing line operations. At the same time, a fish signal microswitch 16 which senses a fish signal and performs a closing operation is also connected.

On the other hand, the motor M is a so-called universal motor equipped with a field coil, and its drive is controlled by a forward/reverse rotation stop operation circuit 17. This forward/reverse rotation stop operation circuit 17 has a pair of contacts 19, 20 for switching the direction of energization by the battery 18 in order to discharge and wind up the fishing line, that is, to cause the motor M to rotate in the forward and reverse directions.
It is configured to be switched by a relay (not shown) which is energized by a coincidence signal issued from 3. Furthermore, a stop contact 21 is inserted in series with the battery 18, and similarly to the above, this stop contact 21 is opened and closed by a relay (not shown) that is energized by a coincidence signal issued from the motor control circuit 13. do. Further, a plurality of, for example, two variable resistors X and Y connected in parallel to each other are connected in series to the field coil 22, and these variable resistors X and Y are arbitrarily switched by a changeover switch 23. It's becoming possible. This changeover switch 23 is operated manually.

After storing the amount of fishing line released in advance in the memory 9, the drum 1 around which the fishing line is wound is automatically driven. 15 is opened, the manual switch 14 is switched to the release position to rotate the motor M in the forward rotation direction, thereby releasing the fishing line to the optimum depth as shown in FIG. The switch 14 is switched to the stop position to stop driving the motor M. When the fishing line is released, the transmitters 4 and 5 emit signals corresponding to the rotation of the drum 1 and are added to the counter 6, but since the signal phase of the transmitter 4 is ahead of that of the transmitter 5, an addition operation is not performed. Then, the addition pulses as shown in FIG. 3 are counted. Furthermore, the memory switch 8 is closed and this count value is stored in the memory 9.
On the other hand, when fishing, as shown in FIG. 3, the search width setting switch 12 is set to a predetermined width position in order to perform a so-called search operation in which the fishing line is moved up and down by a predetermined width, and the length of the fishing line is set at a predetermined width position. When the auto switch 15 is closed after setting the thread remaining setting switch 11 to a desired position to define the upper limit, the groping operation is performed according to the set width as shown in FIG. In this case, as shown in FIG. 3, the counter 6 emits subtraction pulses and addition pulses corresponding to the searching operation, counts them, sends this counted value to the comparator 10, and controls the searching width setting switch 12. When the set value and the count value match, the comparator 10
A coincidence signal from the contact point 19 is applied to the motor control circuit 13, which causes the contact point 19,
20 and sequentially repeat forward and reverse rotation of the motor M. During this searching operation, the lower limit point is set by the stored value in the memory 9, and when the lower limit point is reached, the winding operation is performed. At this time, when a fish signal is detected, the fish signal micro switch 16 closes, and the motor control circuit 13 then connects the contact 19,
20 to reverse the motor M and wind up the fishing line. This winding is performed using the thread remaining setting switch 11.
In other words, the drive of the motor M is stopped at a set length position from the tip of the fishing line depending on the length of the fishing line.
A comparator 10 compares the subtracted value from the remaining yarn setting switch 11 with the setting value of the yarn remaining setting switch 11, and when they match, the motor control circuit 13 opens the stop contact 21. At the time of the next fishing trip, since the depth has been set in advance, the above operation can be repeated by simply opening and closing the auto switch 15. Further, to change the speed of discharging and winding up the fishing line, the changeover switch 23 may be operated manually.

As described above, according to the present invention, once the amount of fishing line released is stored in the memory, not only the searching operation but also the winding up of the fishing line when detecting the fish can be automatically performed, and furthermore, during subsequent fishing. It is also possible to fish continuously without having to set the amount of fishing line discharged again, and it is easy to change the amount of fishing line discharged, which is an excellent effect of labor saving and modernization. It is something that demonstrates the.
