Description

  The present invention provides an operation for automatically returning to a fishing point (hereinafter referred to as a tide stand) even when the fishing boat is swept by a sea current or wind when performing point fishing on a small vessel such as a fishing boat of about 2 to 5 tons. This relates to a shift / tidal device for a small vessel that can perform the tidal operation and the shift operation of the engine clutch remotely (remote control). Note that point fishing refers to fishing while repeating the operation of returning to the original fishing point when the small vessel is not stopped by an anchor and is washed away from the fishing point by a tide for a certain period of time.

  For example, as shown in FIG. 7, the conventional general tide device includes a changeover switch 51 for switching from a normal remote control operation (shift operation) to a tide operation. After switching to the tidal mode, a neutral timer 52 for adjusting the time during which the operator keeps the engine clutch 22 in a neutral state, and a forward time for returning the ship that has flowed during this neutral state to the original point (or The tidal device 50 is provided with a forward timer (reverse timer) 53 for adjusting the reverse time). In other words, in a small vessel equipped with the tidal device 50, if the operator sets the neutral time and the forward time between 1 to 30 seconds, the engine clutch 22 is in the neutral state for the neutral set time. The small ship rides on the tide and flows in the stern direction (or the bow direction), while the small ship switches to the forward state (or reverse state) and moves at a slow speed (about the idling speed of the engine 20) for the set time. Since the operation of moving forward (or moving backward) and returning to the original fishing point is automatically repeated, the operator can be freed from the maneuvering operation and can concentrate on fishing. Reference numeral 41 in FIG. 7 is a portable transmitter, reference numeral 42 in FIG. 7 and FIG. 8 described later is an actuator unit, 26 is a mechanical control head, 27 is a shift lever, 20 is an engine, 21 is a throttle, 22 Is an engine clutch, 23 is a shift, and 24 and 25 are push-pull cables.

  However, in a small vessel not equipped with such a tidal device, the operator operates the shift lever 27 of the control head 26 to switch the engine clutch 22 to the neutral state as shown in FIG. Since it is necessary to repeat the boat maneuvering operation of operating the shift lever 27 again to advance to the original point at a slow speed, not only can not only concentrate on fishing, but also cannot leave the maneuvering position near the control head 26.

  As a prior art related to this type of device, a wireless control of a ship equipped with an accelerator lever for adjusting the engine speed, a forward / reverse switching clutch lever for switching forward and backward, and steering for steering A device that transmits a command signal for an accelerator lever, a forward / reverse switching clutch lever, and steering, receives a command signal transmitted from the wireless transmitter, and outputs a signal corresponding to the command signal Receiver, a control panel that outputs a control signal based on a signal output from the receiver, and a lever power unit that drives an accelerator lever and a forward / reverse switching clutch lever based on the control signal output from the control panel And a steering power unit for driving the steering based on a control signal output from the control panel. Is (e.g., see Patent Document 1).

As other prior arts, a portable housing that can be gripped by a ship operator, a control lever that is provided in the housing and can be rotated in the front-rear direction, and the control lever that is built in the housing is rotated forward. An engine control displacement sensor that sends an engine forward control signal and sends an engine reverse control signal when the control lever is rotated rearward, and a lock capable of holding the control lever in a neutral position A remote control device for a small ship provided with a mechanism has been proposed (see, for example, Patent Document 2).
JP 2000-6891 A JP 2002-137795 A

However, the conventional general tidal device described above has room for improvement in the following points. That is,
1) It is necessary for the operator to set both the neutral time and the forward time (or reverse time), and it takes time to operate and skill is required to make the tide function work properly.

  2) The tidal device is provided separately from the remote control (for example, portable transmitter) that remotely controls the shift (neutral and forward / reverse operation of the engine clutch), throttle (engine speed control) and rudder (steering). Therefore, the operator has to operate two devices, and the operation becomes complicated.

  3) Even when the remote control dial type knob is in the neutral position, in the remote control mode, the electromagnetic clutch in the actuator unit is ON, so the control head is connected to the actuator unit. The remote control shift could not be operated manually. For this reason, in order to manually operate the shift of the control head, it is necessary to either turn off the power of the actuator unit or switch the mode.

  4) Conventionally, an electric control head has been implemented in which the potentiometer (position sensor) reads the position of the control head shift and electrically operates the engine throttle and engine clutch. In the case of a device that does not have a mechanical control head, in other words, it cannot be manually operated when trouble occurs.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described points. In a tidal device including a control head for mechanically operating an engine throttle and an engine clutch via a push-pull cable by a shift operation, one dial is provided. By simply rotating the (knob) and changing the rotation angle from the reference position, you can set the neutral time and forward (or reverse) time for tidal operations at the same time, and set the common dial (knob) to the neutral position. The aim is to provide a small vessel shift and tidal device that can be operated manually by simply shifting the control head.

In order to solve the above problems, a shift / tidal device for a small vessel according to the present invention includes: a) neutralizing a clutch of an engine through a push-pull cable type control head having a throttle lever for manual operation and a shift lever. A shift / tidal device for a small vessel that is remotely operated in a state, a forward state, and a reverse state, and b) a motor that generates a driving force for switching the position of the shift lever, and a push-pull cable for driving the motor. An actuator unit including an electromagnetic clutch for transmitting to or canceling the transmission via the shift lever is provided, a portable transmitter as an electric remote controller is connected to the actuator unit, and the shift lever of the control head is connected to the push-pull cable. Through c) the position of the port tab The transmitter is provided with a dial-type knob that can be rotated clockwise and counterclockwise from the neutral position, and d) the knob from the neutral position to one side within a maximum rotation angle (for example, 150 °). When the knob is rotated to the rotation position, it moves forward, and when the knob is rotated from the neutral position to the other position within the range of the maximum rotation angle (for example, 150 °), it moves backward.
e) When the knob is rotated in both directions from the neutral position within a range narrower than the maximum rotation angle, forward tide and reverse tide are performed respectively, and both forward tide and reverse tide are at the rotation angle of the knob. The forward time, reverse time and neutral time are divided into multiple stages.The forward time, reverse time and neutral time are set in advance for each stage, and the engine speed is idling for both forward and reverse tides. While rotating at a very low speed, the screw rotation is stopped during the neutral time.

  According to the shift / tidal device for a small vessel having the above-described configuration, the forward tide and the reverse tide are automatically adjusted together with the forward / reverse movement of the small vessel simply by rotating one knob and determining the position of the knob. It is easy to operate, and even if the flow of the tide changes, it can respond by changing the position of the knob, and you can concentrate on fishing away from the boat maneuvering position.

  The neutral time in the tidal operation can be set in advance for each stage at the position of the knob corresponding to the forward time or the reverse time, and the neutral time is set to another two switches. ON / OFF is the same as the advance time · 75% · 125% · 150%, while the reverse time is set to another one switch ON / OFF is the same as the advance time -It can be set in two ways of 150%.

  In this way, the neutral time, forward time and reverse time can be selected by turning the switch on and off in consideration of the tide flow and wind strength at the fishing point, so the time setting can be set compared to conventional devices. It is easy and can be set in a short time.

  According to a third aspect of the present invention, the electromagnetic clutch in the actuator unit can be turned off and the shift lever of the control head can be manually operated with the knob rotated to the neutral position.

  In this way, even if the motor in the actuator unit breaks down, the ship can be operated with the engine clutch engaged and disengaged by manually operating the shift lever of the control head.

  Since the shift / tide device according to the present invention has the above-described configuration, it has the following excellent effects.

  ・ Basically, a mechanical control head (remote control stand) that manually turns on and off the engine clutch and controls the engine throttle (accelerator) is used to perform shift and tidal operations. Sometimes manual operation is possible, so safety is high.

  -In effect, the engine clutch can be turned on and off and the timer adjusted at the rotational position of one dial type knob, so the remote control device can be downsized, and the time spent by the tide and the time returned by the propulsive force can be reduced. Tidal operation controlled by a timer is easy and can be set in a short time.

  -Manual operation can be enabled simply by rotating the knob to the neutral position.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a shift / tidal device for a small vessel according to the present invention will be described below with reference to the drawings.

  FIG. 1A is an explanatory diagram showing an entire layout including a tidal device for a small vessel according to an embodiment of the present invention, and FIG. 1B is used for the tidal device of FIG. FIG. 2 is a flowchart showing an operation procedure of the tidal device of the present invention.

  As shown in FIG. 1, the shift / tidal device 1 of the present embodiment includes a throttle 21 that controls the governor of the engine 20 to adjust the rotational speed, and a shift 23 that switches the engine clutch 22 from the neutral state to forward or reverse. Are attached to a small vessel (not shown) that is already equipped with a mechanical control head 26 that can be manually operated via push-pull cables 24 and 25, respectively. Of course, when the mechanical control head 26 is equipped, the shift / tide device 1 can be attached.

  The shift / tide device 1 includes an actuator unit 2 and a wired portable transmitter 3 as an electric remotor controller connected to the unit 2 via an electric wire 4. A motor M, an electromagnetic (excitation) clutch C, a lever L, and a control panel 11 are provided in the actuator unit 2, and a lever L that moves in a specific direction via the electromagnetic clutch C by the rotation of the motor M is provided by a push-pull cable 5. The control head 26 is connected to a rotation operation portion (not shown) of the shift lever 27 of the control head 26. As shown in FIG. 1B, the portable transmitter 3 includes a dial type knob 31 that can be rotated clockwise and counterclockwise from a neutral position. The knob 31 can rotate in both directions at a maximum of 150 °. The position rotated 150 ° clockwise is forward (continuous), and the position rotated 150 ° counterclockwise is backward (continuous). Also, the range from 25 ° to 108 ° in both directions from the neutral position is the forward tide and reverse tide, respectively, and the forward tide and reverse tide both advance or reverse time and neutral time is 1-7 steps It is divided into. Regarding the advance time, the first stage is set to 1 second, the seventh stage is set to 30 seconds, and the second to sixth stages are set to 5 seconds, 10 seconds, 15 seconds, 20 seconds, and 25 seconds. Reference numeral 28 in FIG. 1A denotes a throttle lever for manually operating the throttle 21. The setting of the time is an example and is not limited. The above (continuous) means that the forward-neutral or reverse-neutral state is not repeated by setting the tidal time, but always forward or reverse, and the following is the same.

  Further, the rotational speed of the engine 20 travels at a very low speed close to idling in both forward and backward travel.

  Further, the neutral time is set in advance for each step at the position of the knob 31 corresponding to the forward time or the reverse time, but the same as the forward time when the two dip switches (not shown) are turned ON / OFF. It can be set in four ways:%, 125%, and 150%. The reverse time can be set in two ways, the same as or 150% of the forward time, by turning on / off another dip switch. In addition, the specific numerical value described here is an example to the last, Comprising: It is not limited.

  Here, an example of the procedure of the shift / tidal operation by the shift / tidal device 1 according to the present embodiment will be described. The ship operator (user) moves the knob 31 of the portable transmitter 3 back and forth or sets the tide. When the shift / tidal operation is started as shown in FIG. 2 in a state rotated to a desired position within the range (Step 100), the position of the knob 31 of the portable transmitter 3 becomes the control panel in the actuator unit 2. 11 is read into the central processing unit (CPU) 11 (Step 101). Then, the position of the knob 31 is detected by the CPU (Step 102). In this example, since the voltage changes at the rotation position of the knob 31, the CPU detects the position of the knob 31 by the change in voltage.

  If in the neutral position, a command signal for neutralizing the shift lever 27 of the control head 26 is transmitted (Step 103), and when received by the control panel 11, the electromagnetic clutch C in the actuator unit 2 is switched off ( Step 104), a series of operations ends (Step 120).

  If the position is the forward side, the CPU detects whether the position of the knob 31 is maximum (Step 106). If Yes, a command signal to advance (continuous) is transmitted (Step 107), and the electromagnetic clutch C in the actuator unit 2 is switched ON (Step 108). If No, the forward time and the neutral time are respectively calculated based on the rotation angle of the knob 31 (based on the neutral position) (Step 109), and the engine clutch 22 is operated until the forward time elapses and the neutral time elapses. A command signal for neutralization is transmitted (Step 110), and the electromagnetic clutch C in the actuator unit 2 is switched ON (Step 108).

  If it is the reverse side, the CPU detects whether the position of the knob 31 is maximum (Step 111). If Yes, a command signal for reverse (continuous) transmission is transmitted (Step 112), and the electromagnetic clutch C in the actuator unit 2 is switched ON (Step 108). If No, the reverse time and the neutral time are calculated based on the rotation angle of the knob 31 (based on the neutral position) (Step 113). For example, from a state where a small boat is stopped at a fishing point (not fixed with an anchor) The engine clutch 22 is switched to the neutral state until the neutral time elapses, and a command signal is issued to reverse the engine until the reverse time elapses (Step 114), and the electromagnetic clutch C in the actuator unit 2 is switched ON (Step 108). ).

  Subsequently, the position of the lever L in the actuator unit 2 is read into the CPU, which is fed back as an FB value (Step 115), and the command value and the FB value are compared (Step 116). If the command value (for example, the voltage value generated at the reverse position) is smaller than the FB value (for example, the voltage value generated at the neutral position), the motor M reverses (Step 117), and the engine clutch switches to the reverse direction for the reverse time. As a result, the series of work is completed (Step 120). If the command value (for example, the voltage value generated at the neutral position) is the same as the FB value (for example, the voltage value generated at the neutral position), the motor M continues to be stopped (Step 118), and the series of operations is completed. (Step120). If the command value (for example, the voltage value generated at the forward position) is larger than the FB value (for example, the voltage value generated at the neutral position), the motor M rotates forward (Step 119), and the engine clutch 22 switches to forward for the forward time. The series of work is completed (Step 120). In this example, the command value and the FB value are compared with the voltage value. The engine speed during forward / reverse travel is arbitrarily adjusted by the operator using the throttle lever 28.

  While the knob 31 is located within the range of the tidal operation, the above series of operations (Step 100 to Step 120) are repeatedly performed.

  As described above, when the knob 31 of the portable transmitter 3 is in the neutral position, the electromagnetic clutch C in the actuator unit 2 is turned off, and the shift 27 of the control head 26 can be manually operated. It is explanation about.

  FIG. 3 (a) is an explanatory view showing the entire layout provided with a shift / tidal device for a small vessel according to another embodiment of the present invention, and FIG. 3 (b) is an illustration of the tide device of FIG. 3 (a). FIG. 4 is a flowchart showing an operation procedure of a shift / tidal device according to another embodiment of the present invention. FIG. 4 is a flowchart of a type in which the electromagnetic clutch C is in the ON state, that is, does not switch to OFF even when the knob 31 is in the neutral position. In the case of this embodiment, as shown in FIG. 3A, a power switch 15 is interposed in the middle of a power cable 14 that supplies power to the actuator unit 2. The portable transmitter 3 is the same as that of the above embodiment except that the neutral position of the dial type knob 31 is changed to a position just above and the number of notch positions is changed from 5 to 3 as shown in FIG. To do.

  In the shift / tide device 1 ′ according to the present embodiment, even when the knob 31 of the portable transmitter 3 ′ is switched to the neutral position, the electromagnetic clutch C (see FIG. 1) in the actuator unit 2 ′ is kept in an excited state. Therefore, the electromagnetic clutch C is a remote control mode type that does not turn off. Instead, a power switch 15 is provided, and the actuator unit 2 'is turned off by the power switch 15 to cancel the actuator mode, thereby enabling manual operation of the shift lever 27 of the control head 26. In the case of the present embodiment, an emergency situation is to be avoided by rotating the knob 31 to the forward or reverse position.

  Here, the shift / tide operation operation procedure according to the present embodiment will be described. The operator (user) rotates the knob 31 of the portable transmitter 3 ′ to a desired position within a range where the forward / backward movement or the tide is performed. When the tidal operation is started as shown in FIG. 4 (Step 200), the position of the knob 31 of the portable transmitter 3 ′ is the central processing unit of the control panel 11 (see FIG. 1) in the actuator unit 2 ′. (Step 201). Then, the position of the knob 31 is detected by the CPU (Step 202).

  If in the neutral position, a command signal for neutralizing the shift lever 27 of the control head 26 is transmitted (Step 203), but the electromagnetic clutch C in the actuator unit 2 is kept in the ON state.

  If the position is the forward side, the CPU detects whether the position of the knob 31 is maximum (Step 204). If Yes, a command signal for moving forward is transmitted (Step 205). If No, the forward time and the neutral time are respectively calculated based on the rotation angle of the knob 31 (referenced to the neutral position) (Step 206). The forward time is advanced until the forward time elapses, and the engine clutch 22 is operated until the neutral time elapses. A command signal for neutralization is transmitted (Step 207). Also in this example, since the voltage value changes at the position of the knob 31, it is detected by the voltage difference. For example, a voltage of 2.5 v is generated at the neutral position, 5 v is generated at the forward maximum rotation position, and 0 v is generated at the reverse maximum position.

  If it is the reverse side, the CPU detects whether the position of the knob 31 is maximum (Step 208). If Yes, a command signal for reverse travel is transmitted (Step 209). If No, the reverse time and neutral time are calculated by the rotation angle of the knob 31 (based on the neutral position) (Step 210), for example, from a state where a small boat is stopped at a fishing point (not fixed with an anchor) The engine clutch 22 is set to the neutral state until the neutral time elapses, and a command signal is transmitted to the effect that the vehicle will reverse until the reverse time elapses (Step 211).

  Subsequently, the position of the lever L in the actuator unit 2 'is read by the CPU, and this is fed back as an FB value (Step 212), and the command value and the FB value are compared (Step 213). If the command value (for example, the voltage value generated at the reverse position) is smaller than the FB value (for example, the voltage value generated at the neutral position), the motor M reverses (Step 214), and the engine clutch 22 is switched backward for the reverse time. Instead, the vehicle moves backward, and the series of operations ends (Step 217). If the command value (for example, the voltage value generated at the neutral position) is the same as the FB value (for example, the voltage value generated at the neutral position), the motor M continues to be stopped (Step 215), and the series of operations ends. (Step217). If the command value (for example, the voltage value generated at the forward position) is larger than the FB value (for example, the voltage value generated at the neutral position), the motor M rotates forward (Step 216), and the engine clutch 22 is switched to the forward direction for the forward time. Then, the series of operations is completed (Step 217).

  While the knob 31 is positioned within the range where tide is performed, the above series of operations (Step 200 to Step 217) are repeatedly performed.

  FIG. 5 (a) is an explanatory view showing the entire layout of a small vessel shift / tidal device according to still another embodiment of the present invention, and FIG. 5 (b) is a shift / tidal device / throttle / steering device. FIG. 6 is a flowchart showing an operation procedure of the shift / tidal and throttle of FIG. 5 (b).

  In the case of the present embodiment, as shown in FIG. 5, in addition to the control panel 12 in the actuator unit 2 ″, two sets of motor M, electromagnetic clutch C, and operation for the shift lever 27 and the throttle lever 28, A lever L is provided, one of which is connected to the rotation operation portion of the shift lever 27 via the push-pull cable 5, and the other is connected to the rotation operation portion of the throttle lever 28 via the push-pull cable 6. As shown in Fig. 5 (b), "" includes a dial type knob 31 for the shift / tidal device 1 ", and a throttle operation knob 32 and a steering knob 33 for the engine 20 in a series of lengths. The control panel 12 stores a program for shift / tidal and throttle for the CPU, and a steering knob 33 for the portable transmitter 3. Although provided for steering operation actuator unit is not provided, the steering hydraulic cylinder installed in the stern by the rotation angle of the steering knob 33 (not shown) is operated directly.

  As for the tidal device 1 ″, when the knob 31 is switched to the neutral position as shown in the following operation procedure, the neutral lever is manually operated and the shift lever 27 can be manually operated (Step 101 to Step 120). Any one of the neutral remote control mode types (Step 200 to Step 217) in which the electromagnetic clutch C in the actuator unit 2 ″ is not turned off is selected.

  Next, the procedure of the tide operation according to the present embodiment will be described. The ship operator (user) rotated the knob 31 of the portable transmitter 3 ″ to a desired position within a range where the forward / backward movement or the tide is performed. 6 and after the throttle knob 32 is rotated to a desired position and the operation is started as shown in FIG. 6 (Step 300), it is selected from the flowchart shown in FIG. 2 or FIG. A series of operations (Step 101 to Step 120 or Step 200 to Step 217) related to shift / tidal control according to one operation procedure is performed.

  Subsequently, the position of the throttle operation knob 32 of the portable transmitter 3 ″ is read into the central processing unit (CPU) of the control panel 12 in the actuator unit 2 ″ (Step 301). Then, the CPU calculates a command value (engine speed) of the throttle 21 from the position of the knob 32 (Step 302).

  The position of the throttle operating lever L2 in the actuator unit 2 ″ is read by the CPU and fed back as a throttle FB value (Step 303), and the command value and the FB value are compared (Step 304). If the range) is smaller than the FB value (for example, medium speed rotation range), the motor M2 is reversely rotated (Step 305), the rotational speed of the engine 20 is lowered to the low speed rotation range, and the series of operations is completed (Step 308). If the command value (for example, medium speed rotation region) is the same as the FB value (for example, medium speed rotation region), the motor M2 continues to be stopped (Step 306), and the engine speed is maintained in the medium speed rotation region. When the command value (for example, high speed rotation range) is larger than the FB value (for example, medium speed rotation range), the motor M2 rotates forward (Step 307) and the engine speed is reached. Increased to high speed Is a series of operations are completed (STEP 308). The electromagnetic clutch C2 is maintained to ON.

  While the knob 31 and the knob 32 are maintained at the same rotation angle, the above series of operations (Step 300 to Step 308) are repeatedly performed. Further, in the shift / tide device 1 ″ according to the present embodiment, the throttle 21 of the engine 20 can be remotely operated by the knob 32, so that not only the navigation speed of the small vessel in the forward or reverse state by the knob 31 but also the forward tide. It goes without saying that the speed of navigation during standing and reverse tide can be controlled arbitrarily.

  Although three embodiments of the shift / tidal device of the present invention have been described above, they can be implemented as follows.

  The neutral time and forward or reverse time in forward tide and reverse tide are divided into 7 stages, but can be divided into, for example, 3 to 10 stages.

  The neutral time is changed by turning on / off the dip switch corresponding to the forward time or the reverse time, but may be changed by, for example, a dial type knob or a notch switch.
