Description

Description: TECHNICAL FIELD The present invention relates to an electric reel having a winding speed adjusting function.

(Prior Art) There is known an electric reel that winds a fishing line being fed onto a spool that is rotated by the rotational force of a motor. Some recent electric reels incorporate a microprocessor for control and can keep the winding speed of the fishing line constant. In these electric reels, the winding speed of the fishing line is always detected. When fish is caught, a load is applied to the motor, and when the winding speed of the fishing line decreases, the microprocessor increases the rotation speed of the motor to increase the fishing line speed. The winding speed is accelerated to a predetermined set winding speed to keep the winding speed constant.

(Problems to be Solved by the Invention) However, the above-mentioned conventional electric reels that wind at a constant speed have the following problems.

In the conventional electric reel, the winding speed is controlled to be constant by referring only to the winding speed of the fishing line. In such a configuration, for example, the slippage occurs due to a failure of a spring or the like that applies a pressing force to a contact roller that presses the fishing line wound on the spool in a detecting unit that detects a winding speed of the fishing line. An error may occur in the value, and the microprocessor may determine that the winding speed is lower than the set winding speed even though the winding is actually performed at the set winding speed. If the microprocessor makes such an erroneous determination, the microprocessor controls to increase the rotation speed of the motor, and may actually wind the fishing line at a speed higher than the set winding speed. In addition, if the fishing line is wound at a speed higher than the set winding speed, there is a problem that the hook will come off when the hooked fish is a fish whose mouth is weaker than a fish body.

Accordingly, the present invention provides an electric reel with a winding speed adjusting function capable of preventing a malfunction of an adjusting function for adjusting the winding speed of a fishing line when a fish is hooked and the winding speed of the fishing line is reduced. With the goal.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, a motor for rotating a spool for winding a fishing line, a motor adjusting unit for adjusting a rotation speed of the motor, a winding speed detecting unit for detecting a winding speed of the fishing line, and the motor Load detecting means for detecting the magnitude of the load, a first memory for storing a preset winding speed of the fishing line, and a magnitude of the motor load detected at the start of winding. Second to remember
And the current winding speed of the fishing line detected by the winding speed detecting means is compared with the set winding speed stored in the first memory, and the current winding speed is lower. In this case, the magnitude of the current load of the motor detected by the load detection means is compared with the magnitude of the load of the motor detected at the start of winding stored in the second memory, and the magnitude of the current load is determined. The problem is solved by providing a control means for increasing the rotation speed of the motor via the motor adjusting means to make the winding speed of the fishing line closer to the set winding speed when the value is larger.

(Action) The action will be described.

If the current fishing line winding speed is lower than the set winding speed and the current motor load is larger than the motor load detected at the start of winding, the fish is hooked after the winding starts. It can be determined that the load has increased. Therefore, even if the rotation speed of the motor is increased and the winding speed of the fishing line approaches the set winding speed, the actual winding speed can be kept from exceeding the set winding speed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view of the electric reel of the present embodiment, and FIG. 2 is a block diagram of a control circuit.

 First, the configuration will be described.

In FIG. 1, reference numeral 10 denotes an electric reel,

Can be brought into contact with the outer periphery of the spool 12 on which is wound.
To ensure that the contact roller 18 is brought into contact with the outer periphery of the spool 12, the end of the contact roller 18 side is constantly urged toward the spool 12 by urging means (for example, a spring) not shown. The contact roller 18 is provided rotatably about a shaft 20, and a bevel gear 22 is disposed on one end surface so as to be integrally rotatable.

Reference numeral 30 denotes a rotating unit, which is arranged rotatably about a shaft 32 connected to the main body. The shaft 32 penetrates the outer wall of the tubular body 17 and reaches the inside of the tubular body 17. A magnet 34 is fixed near the periphery of one end face of the rotating unit 30. In addition, a bevel gear 28 is provided on the other end surface of the rotating unit 30 so as to be integrally rotatable. The bevel gear 28 and the contact roller 18
The gear of the bevel gear 22 disposed on the end face of the gear is 1: 1. The bevel gears 22 and 28 are fixed to both ends of a shaft 36 rotatably disposed inside the cylindrical body 17.
They are connected via 4, 26. Since the gear ratio between the bevel gears 24 and 26 is also 1: 1, the contact roller 18 and the rotating unit 30 can rotate at the same rotation speed.

Reference numeral 38 denotes a fixed portion, which is provided on the main body so as to face the end surface of the rotating portion 30 where the magnet 34 is arranged. Two Hall elements H1 and H2 are fixed to the fixing unit 38, and are connected to a control circuit described later. The arrangement of the Hall elements H1 and H2 is arranged so as to be asymmetrical with respect to the rotation center of the rotating unit 30 opposed thereto. The outputs of the Hall elements H1 and H2 become "0" when the magnet 34 approaches, and "1" when the magnet 34 separates (the reverse is also possible). The contact roller 18 and the Hall element
A winding speed detecting means 16 for detecting the winding speed of the fishing line 14 with H1, H2, etc. is constituted.

Reference numeral 40 denotes a control circuit, which is arranged in the main body and has a Hall element H
1. A circuit module including a microprocessor that processes an output signal from H2.

Reference numeral 42 denotes a display unit, which can display characters on an LCD. The display unit 42 displays the amount of reeling out of the fishing line 14, the amount of winding up, and the like.

Reference numeral 44 denotes an input key.
These keys are used to input a set take-up speed and the like to the microprocessor of the control circuit 40.

Next, the control circuit 40 will be described with reference to the block diagram of FIG.

Reference numeral 52 denotes a microprocessor as a control unit, and a ROM (R
The operation of the electric reel 10 is controlled according to an operating system and a control program stored in an ead only memory (54).

Reference numeral 56 denotes a duty ratio (DUTY) control circuit serving as a motor adjusting unit. The motor 58 is a circuit that controls the duty ratio of the applied pulse to adjust the rotation speed of the motor 58.

Reference numeral 60 denotes a motor current detection circuit serving as a load detection means,
The magnitude of the load applied to the motor 58 is detected as a motor current value flowing through the motor 58.

Reference numeral 62 denotes a random access memory (RAM), which includes a first memory 64, a second memory 66, a third memory 68, and a fourth memory 70. In the first memory 64, the set winding speed Vset input by the user from the input key 44 in advance is stored.
The second memory 66 stores the motor current value i ₀ at the time when the spool 12 starts winding the fishing line 14. In the third memory 68, the current winding speed V of the fishing line 14 is stored. The fourth motor 70 stores the current motor current value i.

The signals from the Hall elements H1 and H2 are sent to the microprocessor 52. Microprocessor 52 is a Hall element
The signals from H1 and H2 are processed according to the control program, displayed on the display unit 42, and the rotation speed and the rotation direction of the motor 58 for rotating the spool 12 are controlled.

Here, detection of the winding speed of the fishing line 14 by the winding speed detecting means 16 will be described.

In FIG. 1, when the spool 12 rotates in the direction in which the fishing line 14 is fed, the urging means (not shown) presses the contact roller 18 protruding from the cylindrical body 17 against the outer periphery of the spool 12, so that the rotation of the spool 12 The contact roller 18 also rotates according to the rotation.
The rotation of the contact roller 18 is transmitted to the rotating unit 30 via the bevel gears 22, 24, 26, and 28.
Rotates at the same rotational speed as the contact roller 18. Then, the magnet 34 of the rotating unit 30 causes the Hall element H
1. Pass over H2. At this time, the wall of the cylindrical body 17 is interposed between the magnet 34 and the Hall elements H1 and H2, but since the wall is formed of a non-magnetic material, it does not block the magnetic lines of force of the magnet 34 and the Hall elements H1 and H2 The output changes each time the magnet 34 passes. At positions where the magnet 34 is separated from the Hall elements H1 and H2, the outputs of the Hall elements H1 and H2 are H1 = "1" and H2 = "1". When the magnet 34 first passes through the Hall element H1, the output becomes
H1 = "0" and H2 = "1". In addition, magnet 34 is a Hall element
When passing through H1 and approaching the Hall element H2, the output becomes H1 =
“0”, H2 = “0”. Output from H1 = "0", H2 = "1"
When H1 = "0" and H2 = "0", a phase difference occurs between the outputs of the Hall elements H1 and H2. When the magnet 34 further approaches and passes through the Hall element H2, the output becomes H1 = "1", H2 = "0",
When the magnet 34 moves away from the Hall element H2, the output again becomes H1 =
"1", H2 = "1", and this state continues. The number of rotations of the contact roller 18 is obtained by counting the number of the series of cycles. Further, since the length of the outer circumference of the contact roller 18 is measured in advance and stored in the ROM 54, the amount of the fishing line 14 to be paid out is determined by the microprocessor 52 every time the contact roller 18 rotates once. Can be obtained by adding only the length of. To rewind the fishing line 14, use the input key 44
, A winding command is input to the microprocessor 52, the motor 58 is rotated, and the spool 12 is rotated in the winding direction. At this time, in order to obtain the winding speed V of the fishing line 14, the winding amount per unit time determined by the clock of the microprocessor 52 can be obtained. . The winding amount may be obtained from the product of the number of rotations of the contact roller 18 and the outer circumference of the contact roller 18 in the same manner as the feeding amount. To detect the start of winding of the fishing line 14, the rotation direction of the spool 12 may be detected. The output patterns of the hall elements H1 and H2 when the fishing line 14 is extended are as shown in Table 1.

The microprocessor 52 is configured to output one of the outputs of the Hall elements H1 and H2.
In the cycle, H1 = "0", H2 = "1" → H1 = "0", H2
= “0” → H1 = “1”, H2 = “0” when spool 12
Is determined to be the feeding direction of the fishing line 14. On the other hand, when the spool 12 winds the fishing line 14, the output patterns of the hall elements H1 and H2 are as shown in Table 2.

That is, the outputs of the Hall elements H1 and H2 are H = “1”, H2 = “0” → H1 = “0”, H2 = “0” → H1 = “0” in one cycle,
H2 = "1" and Table 1 have the opposite output pattern. Accordingly, the microprocessor 52 determines that the rotation of the spool 12 is in the winding direction. In order to determine the start of winding by giving a change to the output pattern of the Hall elements H1 and H2, the arrangement of the Hall elements H1 and H2 needs to be asymmetrical with respect to the rotation center of the rotating unit 30. is there. If the Hall elements H1 and H2 are arranged at symmetrical positions with respect to the rotation center of the rotating unit 30, the output pattern becomes the same between the winding and the feeding of the fishing line 14, and it becomes impossible to distinguish them.

Next, the winding speed adjusting function of the electric reel 10 will be described with reference to FIG. 3 (control flowchart of the microprocessor 52).

Power is supplied to the electric reel 10, and a control program is loaded from the ROM 54 to the microprocessor 52 (step 100). Subsequently, each memory 64, 66, 68, 70,.
Is cleared to zero (step 102).

The user can set the winding speed Ve of the fishing line 14 via the input key 44.
Input st (step 104). The set winding speed Vest may be appropriately selected by the user according to the fishing conditions of the fish to be caught. The inputted set winding speed Vest is stored in the first memory 64.
To memorize.

When the set winding speed Vest is set, the user starts fishing. The microprocessor 52 always detects whether the winding of the fishing line 14 has been started (step 106), and repeats the step 106 until it is determined that the winding has started. When the fish is hooked and the user starts the winding of the fishing line 14 by rotating the motor 58, the microprocessor 52 determines in step 106 that winding has started, and the load on the motor 58 at the time of starting winding, that is, the motor current value i _0. Is detected via the motor current detection circuit 60 and stored in the second memory 66 (step 10).
8). At this point, the motor 58 is in a state where no load is applied due to the fact that the fish is hooked. The microprocessor 60 detects the winding speed V of the fishing line 14 via the winding speed detecting means 16 and stores the value in the third memory 68 (step 110). At this time, since the load caused by the fish is hardly applied to the motor 58, the current winding speed V is equal to the set winding speed Vest. Therefore, in step 112, the load of the fish
Until step 8, the state of V = Vest continues, and the microprocessor 52 repeats the control of steps 110 and 112. When the fish is fully pulled, the magnitude of the load applied to the motor 58 increases, and the winding speed V of the fishing line 14 decreases, and Vest> V. Then, the microprocessor 52 shifts the control from step 112 to step 114, detects the current motor current value i via the motor current detection circuit 60, and stores it in the fourth memory 70 (step 114). Then, the motor current value i ₀ at the start of winding of the second memory 66 is compared with the current motor current value i of the fourth memory 70 (step 116). Where i ₀ = i
Then, even if the winding speed V decreases, the magnitude of the load applied to the motor 58 does not change.
Step 52 determines that the duty ratio for controlling the motor 58 does not change without determining that the winding speed V has decreased due to the fish
And the control of 116 is repeated. However, when fish is applied, the load on the motor 58 naturally increases, so that the motor current i increases. Accordingly, since i ₀ <i in step 106, the microprocessor 52 sets the winding speed V to the set winding speed.
In order to approach Vest, the duty ratio control circuit 56 is instructed to increase the duty ratio by a predetermined amount (step 11).
8). As a result, the rotation speed of the motor 58 increases and the fishing line 14
Is increased. Then, the microprocessor 52 detects the current winding speed V and stores it in the third memory 68 (step 120), and checks whether the set winding speed Vest has been reached (step 122). If the set winding speed Vest has not been reached, the process returns to step 118, and the duty ratio is further increased to increase the winding speed V. If it is determined in step 122 that the winding speed V has reached the set winding speed Vest, the process returns to step 110 to prepare for the next winding speed adjustment.

As described above, various preferred embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. is there.

(Effect of the Invention) When the electric reel with the winding adjustment function according to the present invention is used,
Even if the winding speed of the fishing line decreases due to malfunction or delay of the winding speed detecting means, the winding speed does not increase unless fish is applied and the motor load increases. As a result, it is possible to prevent troubles such as an unnecessary increase in the winding speed due to the error in the detected value and a detachment of the hook of the fishing fish due to the unnecessary increase in the winding speed. In addition, since an abnormal increase in the rotational speed of the motor due to the supply of the overcurrent can be prevented, the motor can be protected.
