Description

Technical Field

[0001] This invention relates to a line reel device capable of high-precision tension detection, including when stopped, a fishing line reel, and a winch. Background Technology

[0002] In fishing reels and other line reel devices, by detecting the tension of the line, it is possible to detect any slack and prevent the line from tangling, or to detect the presence of a fish bite and thus effectively fish. Various methods have been proposed in the past for detecting line tension.

[0003] For example, Patent Document 1 discloses a cylindrical rod body constituting a fishing rod for fishing, the rod body having: a cylindrical main body portion formed by firing a prepreg raw material in which synthetic resin is impregnated with carbon fiber; a piezoelectric element strip disposed on the circumferential surface of the main body portion and extending axially; a bottom plug detachably mounted to the rod end of the main body portion; and a boosting unit that boosts the input voltage from the piezoelectric element strip 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 sequentially stacked on the circumferential surface of the main body portion, and the voltage from the boosting unit applies pressure between the first electrode layer and the second electrode layer.

[0004] In addition, Patent Document 2 discloses a fishing sensor that includes: a detection unit that detects the vibration of the fishing line applied to the fishing line due to the fish taking the bait; and a unit that converts the signal into an electrical signal and inputs it into a signal processing circuit to convert the analog changes of the processed signal into different types of sound or light.

[0005] Furthermore, Patent Document 3 discloses a fishing reel having a rotating body for winding fishing line and a support portion that allows displacement of the rotating body corresponding to the tension acting on the fishing line from the rotating body. The fishing reel has a sensor that measures the tension acting on the fishing line based on the displacement of the rotating body. The fishing reel also has a notification device that outputs the measurement results from the sensor, and the notification device and the sensor are each housed in a single waterproof housing.

[0010] Patent Document 3: Japanese Patent Application Publication No. 5-184271 Summary of the Invention

[0011] The problem that the invention aims to solve

[0012] However, in the rod body of Patent Document 1, the rod body is used as the detection object to detect the deformation and vibration of the rod body, but there are the following problems: if the rod body and the fishing line are in a straight state, it cannot be detected, and it can only be detected when the rod body is in a specific position.

[0013] In addition, in the fishing sensor described in Patent Document 2, the fishing line is used as the detection object. The fishing line is bent by setting a guide such as a pulley, and the force applied to the outside is detected at the bending point. However, since the line needs to be bent in order to detect the tension, it will become a resistance when the fishing line is released at high speed, such as when casting. In addition, there is a problem that it is difficult to make the fishing tackle as a whole miniaturized.

[0014] Furthermore, in the fishing reel of Patent Document 3, the rotating body may also be displaced by external forces other than tension, thus making it practically difficult to accurately detect tension based on the displacement of the rotating body.

[0015] The present invention was made in view of the above circumstances, and its object is to provide a winding device having a tension detection unit that can be assembled inside the winding machine and can be miniaturized, eliminating the need for bending the yarn path, and enabling high-precision measurement even when the machine is stopped. Other objects of the present invention become apparent from reference to this specification in its entirety.

[0029] Figure 1 This is an exploded perspective view illustrating a winding device according to one embodiment of the present invention.

[0030] Figure 2 This is an exploded perspective view illustrating a winding device according to one embodiment of the present invention.

[0031] Figure 3 This is a cross-sectional view illustrating a winding device according to one embodiment of the present invention. Detailed Implementation

[0032] Hereinafter, embodiments of the winding device of the present invention will be specifically described with reference to the accompanying drawings. Common structural elements are labeled with the same reference numerals in the various drawings. It should be noted that, for ease of explanation, the drawings are not necessarily shown at an exact scale.

[0033] First, refer to Figures 1 to 3 The structure of a winding device 100 according to one embodiment of the present invention will be described. Furthermore, for the sake of simplicity, only the tension detection mechanism will be described below; parts identical to those in conventional winding devices will be omitted. First, Figure 1 as well as Figure 2 An exploded perspective view of the winding device 100 is shown. Figure 3 A cross-sectional view is shown, taken through a section passing through the central axis of the winding device 100.

[0034] As shown in these figures, 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, hereinafter referred to as the support shaft portion) 2, a rotation limiting portion 3, a recovery portion (recovery unit) 4, a straight-through member 5, a detection portion (detection unit) 6, and a detection portion (detection unit) 7. The spool 1 is formed in a cylindrical shape and configured to wind fishing line through its outer periphery. In the following description, the central axis of the spool 1 is defined as the axis, and its rotation direction is defined as the rotation direction.

[0035] The support shaft 2 is generally cylindrical, and the drum 1 is rotatably supported by the bearing 21. It is also rotatably supported by the main body of the winding device 100 (not shown) via the bearing 22, and rotation can be performed by operating a known operating unit (not shown). This operation winds the wire onto the drum 1. The operating unit allows the support shaft 2 to rotate, which can be achieved through a combination of a user-operated device such as a handle or lever and a power transmission unit such as a gear, belt, or shaft. A power source such as a motor or engine can also be used if needed. Furthermore, a towing device (torque limiter) that limits the transmitted power, or a clutch device that switches the power transmission, can be included. Additionally, a one-way clutch, ratchet, or other reverse-rotation prevention mechanism can be provided in a part of the operating unit to prevent the drum 1 from accidentally reversing.

[0036] Furthermore, the rotation limiting part 3 is fixed to the support shaft part 2, limiting the angular movement of the drum 1 relative to the support shaft part 2 within a predetermined range. In one embodiment of the present invention, the hidden pin 31 provided in the rotation limiting part abuts against both ends of the gap 11 provided in the drum 1. Thus, the drum 1 is configured to be able to rotate relative to the support shaft 2 at an angle ranging from 0° to 60°. Hereinafter, this angle is defined as θ.

[0037] The recovery section (recovery unit) 4 can generate a predetermined recovery force on the drum 1. In one embodiment of the present invention, it can be composed of a spring component (e.g., a torsion spring), one end of which contacts the rotation limiting part 31 and the other end of which contacts the drum 1. Thus, when the torque T acting on the drum 1 is below a predetermined value, the spring force is applied in a manner where θ = 0°. Moreover, it is configured such that the angle θ increases with the increase of the torque. In one embodiment of the present invention, it is configured such that by making the central axis of the torsion spring approximately coaxial with the central axis of the drum 1, the increase in torque T is proportional to the displacement of angle θ. When the value of torque T is above a predetermined value, the rotation limiting part contacts one end of the gap in the drum, thereby achieving an angle θ = 60°. As the recovery section (recovery unit), in addition to the elastic spring described above, other methods of generating recovery force, such as using magnetic force generated by a permanent magnet, can also be used.

[0038] The straight-line member 5 is configured as a generally cylindrical shape and is supported so as to be able to move axially straight relative to the support shaft 2. It receives a rotational force from the drum 1 via the rotational transmission part 51, thereby moving together with the drum 1 in the rotational direction by an angle θ relative to the support shaft 2. A helical cam groove 52 is provided on the side of the straight-line member 5, thereby forming a cam mechanism as a conversion mechanism 10 together with the follower pin 23 fixed to the support shaft 2. Through this cam mechanism, the straight-line member 5 also moves axially according to the rotational movement. That is, it is configured to convert the angular displacement θ of the drum 1 in the rotational direction into an axial movement X of the straight-line member 5. In one embodiment of the present invention, it is configured to move 2 mm axially when the angle θ moves by 60°.

[0039] Furthermore, the conversion mechanism in one embodiment of the present invention is not limited to the structure described above, and other structures can achieve the same effect. For example, internal and external threads are respectively provided on the threaded mechanism, i.e., the drum 1 and the straight-line mechanism 5, so that they are screwed together, and the straight-line member 5 is supported on the support shaft 2 in a straight-line manner, thereby enabling the rotational motion of the drum 1 to be converted into the axial straight-line motion of the straight-line member 5 using the threaded mechanism. In addition, the conversion mechanism in one embodiment of the present invention can also be a mechanism other than a cam mechanism or a threaded mechanism.

[0040] The detected part (detected unit) 6 is fixed to the straight-line member 5, and axial movement can be detected by the detection unit 7 disposed on the main body of the reel. In one embodiment of the present invention, the detected part (detected unit) 6 is a permanent magnet, and the detection part (detection unit) 7 is a known magnetic sensor such as a Hall element. It can be configured to adjust the magnetization characteristics, etc., so that the voltage value of the detection part (detection unit) increases proportionally to the amount of axial movement of the detected part (detected unit) 6.

[0041] Furthermore, the detected section (detected unit) 6 has the characteristic of being symmetrical in the rotational direction. In one embodiment of the present invention, it is formed in a cylindrical shape and magnetized without unevenness in the rotational direction. Therefore, even when the detected unit rotates, the output from the detection unit will not change as long as there is no axial movement.

[0042] Furthermore, the combination of the detected part 6 and the detection part 7 is not limited to the magnetic type described above. Conventional displacement detection methods can be used, such as optical detection methods using photoelectric sensors like PSDs as the detection part, optical detection methods using light shields or reflectors as the detected part, and ultrasonic detection methods using ultrasonic receivers and ultrasonic transmitters as the detection part or using sound wave reflectors as the detected part.

[0043] If the axial displacement of the detected part can be detected in a non-contact manner, the combination of the detected part 6 and the detection part 7 will be better. As a result, sliding resistance can be avoided when the support shaft part 2 is rotated.

[0044] A line winding device 100 according to one embodiment of the present invention is configured to include: a spool 1 capable of winding fishing line; an operation unit for winding line into the spool 1; a support shaft 2 for supporting the spool 1 so that it can rotate; a restoring force generating unit (restoring unit) 4 for generating a restoring force between the support shaft 2 and the spool 1; a limiting unit (rotation limiting unit) 3 for limiting the amount of rotational movement of the spool 1; and a detection unit 7 for detecting the amount of rotational movement of the spool 1.

[0045] According to one embodiment of the present invention, a winding device 100 is provided, which can be equipped with a tension detection unit that can be assembled inside a spool and can be miniaturized, without bending the thread, and can perform high-precision measurement even when stopped.

[0046] One embodiment of the present invention provides a line winding device 100 comprising: a line diameter detection unit that detects the diameter of the fishing line wound on a spool 1; and a tension calculation unit that calculates the tension based on the diameter of the fishing line and the amount of rotational movement of the spool.

[0047] One embodiment of the present invention provides a line winding device 100 comprising: a spool 1 capable of winding fishing line; a support shaft 2 that supports the spool 1 axially for rotation; an operation unit capable of rotating the support shaft 2; a recovery force generating unit (recovery unit) 4 that applies a recovery force between the support shaft 2 and the spool 1; a detection unit 6 capable of moving axially along the support shaft 2; a detection unit 7 that detects the axial displacement of the detection unit 6; and a conversion mechanism 10 that converts the movement of the spool 1 in the direction of rotation and transmits it to the detection unit 6.

[0048] According to one embodiment of the present invention, a winding device 100 is provided, which can be equipped with a tension detection unit that can be assembled inside a spool and can be miniaturized, without bending the thread, and can perform high-precision measurement even when stopped.

[0049] In a winding device 100 according to one embodiment of the present invention, the restoring force generating part (restoring part) 4 is a spring component.

[0050] In a winding device 100 according to one embodiment of the present invention, the conversion mechanism 10 is a cam mechanism (cam structure) or a thread mechanism (thread structure).

[0051] In a winding device 100 according to one embodiment of the present invention, the detection unit 7 is a non-contact position detection unit, which is composed of a light-emitting unit that emits light to the detected unit 6 and a light-receiving unit that receives light from the light-emitting unit.

[0052] In a winding device 100 according to one embodiment of the present invention, a permanent magnet is provided on the detection section 6, and the detection section 7 is a non-contact position detection unit that detects the magnetism of the permanent magnet provided on the detection section 6.

[0053] In a winding device 100 according to one embodiment of the present invention, the detection section 6 is provided with an acoustic wave reflecting section, and the detection section 7 is a non-contact position detection unit that detects acoustic waves from the acoustic wave reflecting section provided in the detection section 6.

[0054] One embodiment of the reel device of the present invention is a fishing reel. Another embodiment of the present invention uses a winch. However, the reel device described in this invention is not limited to fishing reels or winches.

[0055] Next, a method for detecting the tension of the thread acted upon by the winding device 100 will be described in detail. As already described, in the winding device according to one embodiment of the present invention, if torque is applied to the spool 1, the spool 1 moves in the rotational direction relative to the support shaft 2, depending on its magnitude. In one embodiment of the present invention, the recovery section (recovery unit) 4 is configured such that θ = 0° when the torque is less than 10 gcm, and θ = 60° when the torque is greater than or equal to 100 gcm, and the amount of movement θ varies proportionally to the change in torque. Furthermore, the straight-line member 5 moves axially according to the amount of movement θ in the rotational direction of the spool 1 via a cam mechanism. In one embodiment of the present invention, the cam groove 51 is formed in such a way that the amount of movement θ in the rotational direction is proportional to the amount of movement X in the axial direction. As a result, the detection unit 6 provided on the straight-line member 5 moves axially by X, and its movement can be detected by the detection unit (detection unit) 7. Therefore, by observing the output of the detection unit 7, the torque acting on the spool 1 can be calculated.

[0056] Furthermore, the torque acting on the spool 1 is obtained by multiplying the tension T of the fishing line by the winding radius R of the line. The winding radius R of the fishing line can vary depending on the rotation of the spool 1, but the tension T acting on the line can also be calculated by using the winding radius R of the fishing line obtained from other units.

[0057] To obtain the winding radius R of the fishing line, conventionally known methods can be used. For example, there are methods such as measuring the distance from the main body of the reel to the fishing line wound on the outer periphery of the spool using an ultrasonic distance meter, calculating the winding radius R by pre-inputting the initial winding radius Rmax and the line thickness ΔD, and always measuring the amount of rotation of the spool 1 from the initial state, and using a shallow groove-shaped spool (a shape with a small difference between the minimum and maximum diameters and a longer axial length) that can negligible changes in the winding radius within its operating range.

[0058] At this time, even if the drum 1 and the detection unit 6 are rotated by the operating unit, the axial position of the detection unit 6 will not change as long as the torque acting on the drum 1 remains unchanged. The detection unit 6 is symmetrical in the rotational direction, therefore the signal obtained from the detection unit 7 remains unchanged. Thus, the torque acting on the drum 1 can be stably detected regardless of the position of the rotational direction of the support shaft 2. Furthermore, to prevent the output of the detection unit 7 from changing due to axial looseness of the support shaft 2, methods such as pre-reducing the axial clearance of the support shaft 2, pre-biasing it axially using a spring, setting the axial movable amount x to be sufficiently greater than the looseness, and addressing assembly errors can be employed.

[0059] Furthermore, as a method of utilizing the detected tension, information is transmitted to the user. The torque acting on the spool 1 and the tension acting on the fishing line obtained by the above method can be transmitted to the user via an output to a display device such as an LCD and a sound information generating device such as a speaker. Thus, it is possible to determine whether there is a bite or whether the line is slack, or to monitor the status of the reel.

[0060] In addition, as another method of utilizing the detected tension, the tension information can be sent to a microcomputer and its historical records stored in memory, smartphones, or other external devices. This allows for the monitoring of short-cycle and long-cycle changes that are difficult to visually confirm. Furthermore, the tension information can also be used as a control object when feedback control is applied to external devices such as the motor or towing device of the operating unit. This enables various controls, such as winding with constant tension.

[0061] Next, according to one embodiment of the present invention, the winding device can measure the tension acting on the wire without bending the wire path, compared to methods that bend the wire. Therefore, a mechanism for bending the wire path is unnecessary, avoiding an overall increase in the size of the device. Furthermore, since there are no unnecessary bends on the wire path, they can be avoided as obstacles when the wire is released at high speed during casting.

[0062] Furthermore, according to one embodiment of the present invention, the winding device is configured such that, compared to methods for detecting the strain and displacement of winding device structural components, a straight-line member moves axially in response to the torque applied to the drum, and the torque can be obtained by detecting the amount of axial movement. Applying tension to the drum is difficult to achieve in the construction of the winding device by methods other than increasing the line tension, and even when an external force is applied to the main body of the winding device, no torque is applied to the drum. Therefore, compared to methods that detect the strain of the main frame of the shaft-supported drum, stable torque and tension measurements can be achieved despite interference.

[0063] According to one embodiment of the present invention, the winding device can detect tension whether the operating unit is stopped or rotated, compared to the method of detection using a motor.

These structural elements can be modified to have any dimensions, materials, and configurations that fall within the scope of this invention. Furthermore, structural elements not explicitly described in this specification can be added to the described embodiments, and some structural elements described in each embodiment can be omitted.
