Description

Technology Field

[0001] The present invention relates to a line winding device, a fishing reel, and a winch capable of detecting tension with high precision, including a stop attempt. Background Technology

[0002] In line winding devices such as fishing reels, the tension of the line is detected to detect whether line slack occurs, thereby preventing line entanglement in advance, or to detect whether there is a fish, thereby enabling efficient fishing. Various methods have been proposed as methods for detecting line tension.

[0003] For example, Patent Document 1 discloses a rod body that is a cylindrical rod body used for fishing, comprising a cylindrical main body formed by firing a prepreg material in which a synthetic resin is impregnated into carbon fiber, an axially elongated piezoelectric element band disposed on the circumferential surface of the main body, a bottom plug detachably mounted on the rod handle side end of the main body, and a boosting means for boosting an input voltage from the piezoelectric element band disposed on the bottom plug, wherein a first electrode layer, an insulating layer, a light-emitting layer, a second electrode layer, and a surface layer are laminated sequentially from the circumferential surface of the main body, and a voltage from the boosting means is applied between the first electrode layer and the second electrode layer.

[0004] In addition, Patent Document 2 discloses a fishing sensor equipped with a detection unit that detects vibrations applied to a fishing line due to a fish bite, and means for converting the signal into an electrical signal, processing it, inputting it into a signal processing circuit, and converting the analog change of the processed signal into another type of sound or light.

[0005] In addition, Patent Document 3 discloses a fishing reel comprising a rotating body for winding a fishing line, a bearing part that allows displacement of the rotating body corresponding to the tension acting on the fishing line from the rotating body, a sensor that measures the tension acting on the fishing line based on the displacement of the rotating body, and a notification device that outputs the measurement result from the sensor, wherein each of the notification device and the sensor is housed in a single waterproof case.

[0007] However, in the rod body according to Patent Document 1, the rod body is used as a detection target to detect bending or vibration of the rod body, but there was a problem in that detection was only possible when the rod body was in a specific position, such as when the rod body and the fishing line were in a straight line and detection was not possible.

[0008] In addition, the fishing sensor according to Patent Document 2 detects a fishing line and, by providing a guide such as a pulley, bends the fishing line to detect the force applied externally by tension at the bending point, but since it is necessary to bend the line trajectory to detect tension, there is a problem that it can become a resistance when attempting to reel in the fishing line at high speed, such as during casting, and it is also difficult to miniaturize the entire tackle.

[0009] In addition, in the fishing reel according to Patent Document 3, since the rotating body can be displaced by external forces other than tension, there was a problem that it is practically difficult to detect the accurate tension from the displacement of the rotating body.

[0010] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a line winding device having a tension detection unit that can be embedded within a reel and also be miniaturized, and capable of measuring with high precision even when stationary without the need to bend the line trajectory.

Brief explanation of the drawing

[0022] FIG. 1 is a drawing illustrating an exploded perspective view of a string winding device according to one embodiment of the present invention. FIG. 2 is a drawing illustrating an exploded perspective view of a rope winding device according to one embodiment of the present invention. FIG. 3 is a drawing illustrating a cross-sectional view of a rope winding device according to one embodiment of the present invention. Specific details for implementing the invention

[0023] Hereinafter, embodiments of the rope winding device according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are given the same reference numerals throughout the entire drawing. It should be noted that, for the convenience of explanation, each drawing may not necessarily be depicted at an accurate scale.

[0024] First, with reference to FIGS. 1 to 3, the configuration of a string winding device (100) according to one embodiment of the present invention will be described. Also, for the sake of brevity, the following description will only cover the location of the tension detection mechanism, and the description of locations similar to those of a conventional string winding device will be omitted. First, FIGS. 1 and 2 show an exploded perspective view of the string winding device (100), and FIG. 3 shows a cross-sectional view taken from a cross-section passing through the central axis of the string winding device (100).

[0025] As illustrated in these drawings, a line winding device (100) according to one embodiment of the present invention comprises a spool (1), a support shaft portion (also called a support shaft, but hereinafter referred to as the support shaft portion) (2), a rotation regulating portion (3), a restoration portion (restoration means) (4), a straight member (5), a detection portion (detection means) (6), and a detection portion (detection means) (7). The spool (1) is formed in a cylindrical shape and is configured to enable winding a fishing line by its outer circumference. In addition, in the following description, the central axis direction of the spool (1) is defined as the axial direction, and the rotation direction is defined as the rotation direction.

[0026] The support shaft portion (2) is formed in a roughly cylindrical shape and rotatably supports the spool (1) by means of a bearing (21). Additionally, it is rotatably supported by means of a bearing (22) with respect to the main body portion of a line winding device (100) not shown, and can be rotated by operating a known operating means not shown likewise. By this operation, the line can be wound onto the spool (1). The operating means can be realized by a combination of a device that can rotate the support shaft portion (2) and receives user operation, such as a handle or lever, and a power transmission means such as a gear, belt, or shaft. If necessary, a power source such as a motor or engine may be used. Additionally, it may be equipped with a drag device (torque limiter) that limits the transmitted power, or a clutch device that switches whether or not power is transmitted. Furthermore, a reverse prevention mechanism such as a one-way clutch or a ratchet may be provided in a part of the operating means to prevent the spool (1) from inadvertently rotating in reverse.

[0027] Additionally, the rotation regulating part (3) is fixed to the support shaft part (2) and regulates the amount of angular movement of the spool (1) relative to the support shaft part (2) within a predetermined range. In one embodiment of the present invention, a dowel (31) provided in the rotation regulating part is configured to strike both ends of the gap (11) provided in the spool (1). By doing so, the spool (1) is configured to rotate at an angle ranging from 0° to 60° relative to the support shaft (2). Subsequently, this angle is defined as θ.

[0028] The restoring member (restoring means) (4) can generate a predetermined restoring force on the spool (1). In one embodiment of the present invention, it may be configured by a spring member (e.g., a torsion spring), with one end in contact with the rotation regulating member (31) and the other end in contact with the spool (1). Accordingly, when the torque T acting on the spool (1) is less than or equal to a predetermined value, the spring is compressed so that θ = 0°. And, as the torque increases, the angle θ is configured to increase. In one embodiment of the present invention, by making the central axis of the torsion spring approximately coaxial with the central axis of the spool (1), the amount of increase in torque T and the amount of displacement of angle θ are proportional, and when the value of torque T is greater than or equal to a predetermined value, the rotation regulating member and one end of the air gap of the spool come into contact, so that the angle θ = 60°. As for the restoring member (restoring means), other methods of generating a restoring force may be used, such as using magnetic force generated by a permanent magnet, in addition to the elastic spring as described above.

[0029] The straight member (5) is configured in a roughly cylindrical shape and is supported so as to be able to move straight in the axial direction with respect to the support shaft (2). By receiving a rotational transmission force from the spool (1) through the rotational transmission part (51), it moves in the rotational direction together with the spool (1) by an angle θ with respect to the support shaft (2). A cam groove (52) formed in a spiral shape is provided on the side portion of the straight member (5), thereby forming a cam mechanism as a conversion mechanism (10) together with a follower pin (23) fixed to the support shaft (2). By this cam mechanism, the straight member (5) also moves in the axial direction according to rotational movement. That is, the amount of displacement θ in the rotational direction of the spool (1) is configured to be converted into the amount of movement X in the axial direction of the straight member (5), and in one embodiment of the present invention, it is configured to move 2 mm in the axial direction when the angle θ moves by 60°.

[0030] In addition, the conversion mechanism in one embodiment of the present invention is not limited to the above configuration, and the same effect can be realized in other configurations. For example, a screw mechanism, that is, a female screw portion and a male screw portion are provided in the spool (1) and the straight-line mechanism (5), respectively, and screw-coupled, and the straight-line member (5) is supported so as to move straight with respect to the support shaft (2), so that the rotational motion of the spool (1) can be converted into the axial straight-line motion of the straight-line member (5) by the screw mechanism. In addition, the conversion mechanism in one embodiment of the present invention may be a mechanism other than a cam mechanism or a screw mechanism.

[0031] The detection unit (detection means) (6) is fixed to the straight member (5) and enables axial movement to be detected by the detection means (7) disposed on the reel body. In one embodiment of the present invention, the detection unit (detection means) (6) is a permanent magnet, and the detection unit (detection means) (7) is a known magnetic sensor such as a Hall element. The magnetization characteristics, etc., can be configured to be adjusted so that the voltage value of the detection unit (detection means) increases in proportion to the amount of axial movement of the detection unit (detection means) (6).

[0032] In addition, the detection part (detection means) (6) has a characteristic of being symmetric in the rotational direction. In one embodiment of the present invention, it is formed in a cylindrical shape and magnetized without non-uniformity in the rotational direction. By doing so, even when the detection means rotates, the output from the detection means can be configured so that there is no change in the axial movement amount.

[0033] In addition, the combination of the detection unit (6) and the detection unit (7) is not limited to the magnetic type as described above. Conventionally known displacement detection methods may be used, such as an optical detection method in which a photo sensor, for example, a PSD, is used as the detection unit and a light-blocking plate or a reflector is used as the detection unit, or an ultrasonic detection method in which an ultrasonic receiver and an ultrasonic transmitter are used as the detection unit and a sound wave reflector is used as the detection unit.

[0034] The combination of the detection part (6) and the detection part (7) is better if it can detect the axial displacement of the detection part without contact. By doing so, the occurrence of sliding resistance when the support shaft part (2) is rotated can be avoided.

[0035] A line winding device (100) according to one embodiment of the present invention is configured to have a spool (1) capable of winding a fishing line, an operating unit that performs a line winding operation on the spool (1), a support shaft unit (2) that rotatably supports the spool (1), a restoring force generating unit (restoring unit) (4) that generates a restoring force between the support shaft unit (2) and the spool (1), a regulating unit (rotation regulating unit) (3) that regulates the amount of rotational movement of the spool (1), and a detection unit (7) that detects the amount of rotational movement of the spool (1).

[0036] By means of a string winding device (100) according to one embodiment of the present invention, it is possible to provide a string winding device having a tension detection unit that can be embedded in a reel and also be miniaturized, and can measure with high precision even when stopped without needing to bend the string trajectory.

[0037] A line winding device (100) according to one embodiment of the present invention is configured to have a fishing line diameter detection unit that detects the diameter of a fishing line wound on a spool (1), and a tension calculation unit that calculates tension from the diameter of the fishing line and the amount of rotational movement of the spool.

[0039] By means of a string winding device (100) according to one embodiment of the present invention, it is possible to provide a string winding device having a tension detection unit that can be embedded in a reel and also be miniaturized, and can measure with high precision even when stopped without needing to bend the string trajectory.

[0040] In a rope winding device (100) according to one embodiment of the present invention, the restoring force generating part (restoring part) (4) is a spring member.

[0041] In a string winding device (100) according to one embodiment of the present invention, the conversion mechanism (10) is a cam mechanism (cam structure) or a screw mechanism (screw structure).

[0042] In a rope winding device (100) according to one embodiment of the present invention, the detection unit (7) is a non-contact position detection means and is composed of a light-emitting unit that emits light to the detection unit (6) and a light-receiving unit that receives light from the light-emitting unit.

[0043] In a string winding device (100) according to one embodiment of the present invention, a permanent magnet is provided in the detection unit (6), and the detection unit (7) is a non-contact position detection means and is a magnetic detection unit that detects the magnetism of the permanent magnet provided in the detection unit (6).

[0044] A string winding device (100) according to one embodiment of the present invention is provided with a sound wave reflector in the detection unit (6), and the detection unit (7) is a non-contact position detection means and is a sound wave detection unit that detects sound waves from the sound wave reflector provided in the detection unit (6).

[0045] A line winding device according to one embodiment of the present invention is a fishing reel. In addition, a line winding device according to one embodiment of the present invention is a winch. Here, the line winding device according to one embodiment of the present invention is not limited to a fishing reel or a winch.

[0046] Next, a method for detecting tension acting on a line by the line winding device (100) will be described in detail. As previously explained, in a line winding device according to one embodiment of the present invention, when torque is applied to a spool (1), the spool (1) moves in a rotational direction relative to the support shaft (2) according to the magnitude thereof. In one embodiment of the present invention, a restoration part (restoration means) (4) is configured such that when the magnitude of the torque is 10 g / cm or less, θ=0°, and when it is 100 g / cm or more, θ=60°, and in the range therebetween, the amount of movement θ changes proportionally to the amount of change in torque. Then, by means of a cam mechanism, a straight member (5) moves in the axial direction according to the amount of movement θ in the rotational direction of the spool (1). In one embodiment of the present invention, a cam groove (51) is formed such that the amount of movement θ in the rotational direction and the amount of movement X in the axial direction are proportional. Accordingly, since the detection means (6) provided in the straight member (5) moves by X in the axial direction, the movement can be detected by the detection unit (detection means) (7). Therefore, by observing the output of the detection unit (7), the torque acting on the spool (1) can be calculated.

[0047] Additionally, the torque acting on the spool (1) is the product of the tension T acting on the fishing line and the winding radius R of the line. The winding radius R of the fishing line may vary depending on the amount of rotation of the spool (1), but the tension T acting on the line can also be calculated by obtaining the winding radius R of the fishing line by other means.

[0048] Conventionally known methods can be used to obtain the winding radius R of the fishing line. For example, there are methods such as measuring the distance from the main body of the line winding device to the fishing line wound on the outer periphery of the spool using an ultrasonic distance meter, or calculating the line winding radius R by inputting the line winding radius Rmax and line thickness ΔD in the initial state in advance and constantly measuring the amount of rotation of the spool (1) from the initial state, or using a shallow groove-shaped spool (a shape with a small difference between the minimum diameter and the maximum diameter and an axially long shape) which can ignore changes in the line winding radius in the usage range.

[0049] At this time, even if the spool (1) or the detection means (6) rotates by means of operation, if there is no change in the torque acting on the spool (1), the axial position of the detection means (6) does not change. Since the detection means (6) is symmetrical in the direction of rotation, there is no change in the signal obtained from the detection means (7). Therefore, the torque acting on the spool (1) can be stably detected regardless of the position in the direction of rotation of the support shaft (2). In addition, to prevent the output of the detection means (7) from changing due to the axial backlash of the support shaft (2), methods such as making the axial margin of the support shaft (2) small, shifting it axially by means of a spring, or setting the axial movable amount x sufficiently larger than the amount of backlash or assembly error can be taken.

[0050] In addition, as a method of utilizing the detected tension, information is transmitted to the user. The torque acting on the spool (1) or the tension acting on the fishing line obtained by the above-described method can be transmitted to the user by outputting it to a display device such as an LCD or a sound information generating device such as a speaker. By doing so, it is possible to determine whether there is a fish or whether there is slack in the line, or to determine the state of the line winding device.

[0051] In addition, as another method of utilizing the detected tension, the tension information may be sent to a microcomputer to store its history in memory or external devices such as smartphones. This allows for the detection of short-period or long-period changes that are difficult to observe. Furthermore, the tension information may be used as a control target for feedback control of external devices, such as motors of operating means or drag devices. This enables the realization of various controls, such as winding at a constant tension.

[0052] Next, according to a line winding device according to one embodiment of the present invention, the tension acting on the line can be measured without bending the line trajectory, compared to a method of bending the line. As a result, a mechanism for bending the line trajectory is unnecessary, and the overall size of the device can be avoided. In addition, since there are no unnecessary bending points in the line trajectory, it is possible to avoid obstacles when the line travels at high speed, such as during casting.

[0053] In addition, according to a line winding device according to one embodiment of the present invention, compared to a method for detecting deformation and displacement of a reel component, a straight member is configured to move axially according to the torque applied to the spool, and torque can be obtained by detecting the amount of axial movement. In order to apply tension to the spool, it is often difficult to achieve by methods other than increasing the line tension due to the structure of the line winding device, and no torque is applied to the spool even when an external force is applied to the main body of the line winding device. In this regard, compared to a method for detecting deformation of a main body frame that axially supports the spool, it is possible to achieve stable torque measurement and tension measurement against disturbances.

[0054] According to a rope winding device according to one embodiment of the present invention, compared to a method of detection by a motor, it is possible to detect tension even when the operating means is stopped or rotating.

Additionally, components not explicitly described herein may be added to the described embodiments, and parts of the components described in each embodiment may be omitted.
