Description

[Detailed Description of the Invention] The present invention relates to a depth setting circuit for a fishing machine that is set to release a fishing line to a required depth.

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, in conventional fishing machines, the motor is driven to rotate the line winding drum in the forward and reverse directions simply by operating a switch.
Furthermore, as shown in Japanese Patent Application Laid-Open No. 121094/1983, there is a known device equipped with a digital setting device that can be set to release the fishing line to an optimum depth. However, the former method requires manual switch operation when discharging and reeling in, which is time-consuming and does not offer any labor savings. Determining the amount to be released relies on intuition, but this was the reality. In particular, in the latter case, if you set the release amount learned by intuition on the digital setting device, you can automatically release the fishing line to the required depth from now on, but the release amount that should be set on the digital setting device Knowing this has relied on intuition, which requires skill and has not led to anything that can promote modernization, and it is not easy to deal with situations where the position of fish stocks changes over time, such as with migratory fish. It had various problems such as.

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 that is rotationally driven by a motor, and counts the amount of fishing line released and the amount of winding based on the signal. A memory is connected to the addition/subtraction counter to store the required amount of fishing line to be released based on the counted value, and the addition/subtraction counter and the memory include:
The stored value is compared with the count value based on the rotation of the line winding drum, and when the comparison values match, a comparator is connected to provide a motor reversal signal to the motor control circuit, thereby adjusting the fishing line to the optimum depth. By storing the released amount in memory, the amount of fishing line released can be set without relying on intuition, making it easy for even inexperienced users to handle, as well as setting the depth of the fishing machine that can respond to the constantly changing fish school layer. The purpose is to provide a circuit.

An embodiment of a depth setting circuit for a fishing machine according to the present invention will be described below with reference to the drawings. As shown in FIG. 1, the bobbin winding drum 1 is rotatably driven by a motor via a transmission mechanism 2 such as a belt. A rotary plate 3 with a partially cut out part is attached to the rotating shaft of the drum 1. In this case, a depth detection roller is provided which rotates when the fishing line wound around the drum 1 is released and wound up. The rotating plate 3 is controlled by the rollers to control the number of rotations of the drum,
In other words, it rotates forward according to the amount of fishing line released and the amount of winding up.
Also, it is configured to be reversed. Transmitters 4 and 5 are provided near the rotary plate 3 so as to be orthogonal to the plate surface, and the number of signals is determined by the cutout 3a of the rotary plate 3 as the transmitters 4 and 5 rotate. Although a detection element such as a photointerrupter is used as described above, the present invention is not limited to this, and various other detection elements can also be used. Further, an addition/subtraction counter 6 is connected to the transmitters 4, 5;
Addition or subtraction is performed depending on the oscillation time difference between the pulses emitted from the transmitter 5. When the motor M rotates in the normal direction when releasing the fishing line, the transmitter 4 emits a pulse whose phase is more advanced than the transmitter 5, so the addition operation is performed.
Conversely, when the oscillator 5 oscillates a pulse whose phase is more advanced than that of the oscillator 4, a subtraction operation is performed. Further, the addition/subtraction counter 6 is configured to convert into a numerical value in units of 1 meter in consideration of 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 counter. The counted value of this counter 6 is readably introduced into a display 7, and is supplied to a memory 9 for storage by closing a memory switch 8, and is also sent to a comparator 10. The comparator 10 compares the counted value with the stored value and issues a motor reversal signal when the values match.The motor control circuit receives this motor reversal signal and causes the motor M to be reversed by the motor forward/reverse stop circuit 17. , that is, it is controlled to rotate in the winding direction of the fishing line. A manual switch 14 is connected to the motor control circuit 13 in order to manually rotate the motor M in the normal direction, and to reverse and stop the motor M, as well as an auto switch that opens and closes the motor M to automatically drive the motor M based on the counted value, stored value, etc. Connect 15.

On the other hand, the motor M has a field coil 22.
The drive is controlled by a forward/reverse rotation stop circuit 17 using a so-called universal motor equipped with a motor. It has contacts 19, 20 and a stop contact 21 for driving and stopping the motor M. These contacts 19, 20, 21 are configured to be switched by a relay (not shown) energized by a drive signal issued from the motor control circuit. In addition, the field coil 22
In this example, a plurality of, for example, two variable resistors X and Y connected in parallel are connected in series, and these variable resistors X and Y are manually operated by a changeover switch 2.
3, which can be switched at will, and is configured so that the winding and discharging speeds of the fishing line can be changed as appropriate.

Therefore, in order to store the amount of released fishing line in the memory 9, first, with the auto switch 15 opened, switch the manual switch 14 to the release position and drive the motor M in the forward rotation direction. After the fishing line is released to the optimum depth as shown in FIG. 2, the manual switch 14 is switched to the stop position to stop the motor M from driving. When the fishing line is released, the transmitters 4 and 5 emit signals corresponding to the rotation of the drum 1, which are added to the counter 6, but since the transmission phase of the transmitter 4 is ahead of the transmitter 5, an addition operation is performed. Then, add pulses as shown in FIG. 3 are counted. Next, if the memory switch 8 is closed and this count value is stored in the memory 9, the comparator 10 can calculate the value of the addition/subtraction counter 6 as the fishing line is released without having to set a new depth. The value stored in the memory 9 is compared with the value stored in the memory 9, and when they match, the motor control circuit 13 controls the motor M to be reversed via the motor forward/reverse rotation stop circuit 17.

In this embodiment, when a fish signal is detected in the motor control circuit 13, the fish signal micro switch 16 is connected to close the motor control circuit 13 in order to reverse the motor M, that is, to wind up the fishing line, and also to send a fish signal to the comparator 10. A line remaining setting switch 11 is connected which can detect and arbitrarily set the upper limit point of winding according to the length of the fishing line so that the so-called starting part is not wound into the drum 1 when the fishing line is wound up. This set value is compared with the count value of the addition/subtraction counter 6 by a comparator 10, and the winding operation is stopped. Furthermore, when fishing, the comparator 10
As shown in FIG. 2, a search width setting switch 12 is connected to perform a so-called search operation in which the fishing line is moved up and down by a predetermined width. The winding operation is performed when the lower limit point is reached. In such an operation, the comparator 10 compares the count value of the addition/subtraction counter 6 with the value stored in the memory 9, and moves the fishing line up and down by a predetermined width. With such a configuration, it is possible to fully automatically perform the fishing line release, groping operation, and winding operation when a fish signal is detected.

As described above, according to the depth setting circuit of the fishing machine according to the present invention, if the fishing line is released in advance to the depth of the water or to the fish school layer and this release amount is stored in the memory, a new one can be set at the time of subsequent fishing. There is no need to measure the amount of fishing line released, and fishing can be performed continuously.Furthermore, the amount of fishing line released, that is, the depth, can be easily set, and the depth can be changed at will in response to changes in water depth or fish school layer. It is suitable for fully automating fishing machines, and has great effects such as promoting labor saving in the fishing industry.
