Description

The present invention relates to a fishing line winding machine used to wind a supply of fishing line in small portions onto small spools.

Conventionally, as this type of yarn winding machine, for example, one having a configuration disclosed in Patent Document 1 is known. The yarn winding machine disclosed in Patent Document 1 includes a yarn supplying bobbin that supplies a yarn, a winding bobbin rotation drive device that rotationally drives a winding bobbin (small spool) that winds the supplied yarn, and a traverse guide that is provided in front of the winding bobbin rotation drive device and is driven to traverse the yarn when the yarn is wound onto the winding bobbin.
However, in the yarn winding machine disclosed in Patent Document 1 and the like, the yarn is traversed by a traverse guide when it is wound onto a winding bobbin (small spool), which places a heavy burden on the yarn during winding. As a result, the yarn wound onto the winding bobbin is prone to developing a curl, which may result in a deterioration in yarn quality. Furthermore, because the yarn is wound onto the winding bobbin from an angle relative to the central axis (rotation axis) of the winding bobbin, it is difficult to wind the yarn neatly and in an aligned manner.

Therefore, the present applicant has previously proposed a yarn winding machine that can reduce the burden on the yarn during winding, improve the quality of the yarn, and easily wind the yarn neatly and in an aligned manner (see Patent Document 2).
The yarn winding machine disclosed in Patent Document 2 is a yarn winding machine that winds supplied yarn onto a small spool by rotating the small spool, and is equipped with a spool holding means that holds the small spool.When winding the yarn, the spool holding means rotates around the central axis of the small spool while moving back and forth in the direction of the central axis of the small spool.
With this type of yarn winding machine, the yarn to be wound does not traverse, but the spool holding means moves back and forth along the central axis of the small spool while rotating around the central axis of the small spool, thereby reducing the burden on the yarn during winding. As a result, the yarn wound onto the small spool is less likely to develop a curl, improving the quality of the yarn. Furthermore, since the yarn can be wound onto the small spool in a direction perpendicular to the central axis (axis of rotation) of the small spool, it is easy to wind the yarn neatly and in an aligned manner.

Furthermore, the yarn winding machine disclosed in Patent Document 2 further includes a control means for controlling the yarn winding machine, a tension detection means for detecting the tension of the yarn during winding, and a tension adjustment means for adjusting the tension of the yarn during winding, and the tension adjustment means includes a horizontally movable guide pulley around which the yarn is wound, and a drive mechanism for horizontally moving the guide pulley.The control means controls the drive mechanism to horizontally move the guide pulley in a direction to loosen the yarn tension when the yarn tension detected by the tension detection means becomes higher than a predetermined value, and controls the drive mechanism to horizontally move the guide pulley in a direction to increase the yarn tension when the yarn tension detected by the tension detection means becomes lower than the predetermined value.
This configuration allows the yarn tension to be maintained at an appropriate value during winding, preventing irregular winding. Furthermore, in this case, the yarn tension can be kept constant and low when wound onto the small spool (the yarn can be wound with the minimum necessary tension). This prevents the yarn from becoming kinked when wound onto the small spool and from breaking when the yarn is used. Furthermore, the yarn tension can be adjusted to an appropriate value at any time without exerting pressure on the yarn (reducing the load on the yarn). Furthermore, adjusting the yarn tension by horizontally moving the guide pulley allows for a smaller vertical size of the yarn winding machine while increasing the yarn tension adjustment range. Furthermore, the yarn tension can be stably adjusted without being affected by external factors such as gravity, making it easier to maintain a constant yarn tension. As a result, the yarn can be neatly wound.

Japanese Patent Application Laid-Open No. 2007-238245 JP 2018-020854 A

The fishing line winding machine disclosed in Patent Document 2 is capable of increasing the line tension adjustment range while also being compact in height. However, in recent years, there has been a demand for fishing line winding machines that allow for even greater line tension adjustment range in order to accommodate a variety of fishing lines with different physical properties. There is also a demand for even smaller fishing line winding machines.

The present invention was made in response to the above demands, and aims to provide a fishing line winding machine that is even more compact while allowing for greater adjustment of the fishing line tension.

In order to achieve the above object, the fishing line winding machine according to the present invention is configured as follows:
(1) A fishing line winding machine that rotates a large spool to supply fishing line, and then rotates a small spool to wind the fishing line onto the small spool,
The fishing line winding device includes a control means for controlling the fishing line winding machine, a tension detection means for detecting the tension of the fishing line during winding, and a tension adjustment means for adjusting the tension of the fishing line during winding,
The tension adjusting means includes a horizontally movable guide pulley around which the fishing line unwound from the large spool is hooked, a first auxiliary pulley fixed to the end of the guide pulley's movement path in the direction in which the tension is released, around which the fishing line unwound from the guide pulley is hooked and which turns the fishing line back onto the guide pulley, and a drive mechanism for horizontally moving the guide pulley.
The control means controls the drive mechanism to move the guide pulley horizontally in a direction to loosen the tension of the fishing line when the tension of the fishing line detected by the tension detection means becomes higher than a predetermined value, and controls the drive mechanism to move the guide pulley horizontally in a direction to increase the tension of the fishing line when the tension of the fishing line detected by the tension detection means becomes lower than the predetermined value.

The above-described configuration (1) of the fishing line winding machine of the present invention has the following advantages.
That is, according to the configuration (1) above, the tension adjustment means includes a horizontally movable guide pulley around which the fishing line unwound from the large spool is hooked, and a first auxiliary pulley fixed to the end of the guide pulley's movement path in the direction of tension release, around which the fishing line unwound from the guide pulley is hooked and which turns the fishing line back around the guide pulley. This allows the fishing line unwound from the large spool to be turned back between the guide pulley and the first auxiliary pulley. As a result, compared to the case of Patent Document 2, the fishing line tension can be adjusted over a larger range with a smaller movement of the guide pulley (greater adjustment range for the fishing line tension). Furthermore, because the horizontal movement of the guide pulley can be reduced, the fishing line winding machine can be made smaller in size in the lateral direction.
Therefore, according to the configuration of (1) above, it is possible to provide a fishing line winding machine that can be made even more compact while allowing for a greater adjustment margin for the tension of the fishing line.

In the above-mentioned configuration (1) of the fishing line winding machine of the present invention, it is preferable to configure it as described in (2) and (3) below.

(2) In the configuration described in (1) above, the fishing line unwound from the large spool is folded back multiple times between the guide pulley and the first auxiliary pulley. According to the preferred configuration described in (2) above, it is possible to adjust the fishing line tension over a larger range (further increasing the adjustment range for the fishing line tension) with a smaller movement of the guide pulley.

(3) In the configurations (1) and (2) above, the fishing line unwound from the large spool is hooked on the side of the guide pulley's movement path that loosens the tension, between the large spool and the tension adjustment means, and a second auxiliary pulley is fixed to guide the fishing line to the guide pulley. According to the preferred configuration of (3) above, the portion of the fishing line guided by the guide pulley that supports the fishing line can be kept constant regardless of the amount of fishing line remaining on the large spool. As a result, uniform tension adjustment of the fishing line is possible regardless of the amount of fishing line remaining on the large spool.

The present invention provides a fishing line winding machine that is even more compact and allows for greater adjustment of the fishing line tension.

FIG. FIG. 2 is an enlarged front view illustrating the operation of a tension adjusting means, which is a component of the fishing line winding machine according to one embodiment of the present invention.

The present invention will be described in more detail below using preferred embodiments. However, the following embodiments are merely examples of how the present invention is realized, and the present invention is not limited to these.

[Overall configuration of fishing line winding machine]
First, the overall configuration of a fishing line winding machine according to one embodiment of the present invention will be described with reference to FIGS.

Figure 1 is a front view showing the general configuration of a fishing line winding machine according to one embodiment of the present invention, and Figure 2 is a right side view of Figure 1.

1 and 2, the fishing line winding machine 100 of this embodiment includes a fishing line supply mechanism 40 that supplies fishing line 35, a fishing line winding mechanism 50 that winds up the fishing line 35, and a winding amount measurement mechanism 60 that measures the amount of fishing line 35 wound (winding length) by the fishing line winding mechanism 50. A large spool 30 around which the fishing line 35 is wound is removably attached to the fishing line supply mechanism 40, and the large spool 30 is driven to rotate by a payout motor (not shown). A small spool 45 around which the fishing line 35 is wound is removably attached to the fishing line winding mechanism 50, and the small spool 45 is driven to rotate by a winding motor (not shown). The winding amount measuring mechanism 60 is also equipped with a length measuring encoder 55 that measures the amount of fishing line 35 fed (the amount of fishing line 35 wound by the fishing line winding mechanism 50) based on its own rotational displacement, and the fishing line 35 is wound around the length measuring encoder 55. The fishing line supply mechanism 40 supplies the fishing line 35 by rotating the large spool 30. The fishing line winding mechanism 50 winds the fishing line 35 supplied from the fishing line supply mechanism 40 onto the small spool 45 by rotating the small spool 45. The motors that rotate the large spool 30 and the small spool 45 are driven synchronously by pushing a push switch (not shown) on the fishing line winding machine 100, and are stopped when the amount of fishing line 35 fed by the length measuring encoder 55 reaches a preset value.

The fishing line winding machine 100 of this embodiment further comprises two upper and lower tension detection means (tension sensors) 70, which are provided between the winding amount measurement mechanism 60 and the fishing line winding mechanism 50 and detect the tension of the fishing line 35 during winding, and a tension adjustment means 80, which is provided between the fishing line supply mechanism 40 and the winding amount measurement mechanism 60 and adjusts the tension of the fishing line 35 during winding.
Here, the upper tension detection means 70 is used when reeling in a thin fishing line 35, and the lower tension detection means 70 is used when reeling in a thick fishing line 35. The tension adjustment means 80 is controlled by a control means (not shown) that controls the fishing line winding machine 100. That is, the control means controls the tension adjustment means 80 based on the tension of the fishing line 35 detected by the tension detection means 70, and maintains the tension of the fishing line 35 at a "predetermined value" (if the tension of the fishing line 35 during reeling changes, the tension adjustment means 80 adjusts the tension of the fishing line 35 as needed).

In this embodiment, the "predetermined value" includes not only a specific threshold value, but also a range of values between a preset minimum and maximum value. The "predetermined value" may be a value set by the operator of the fishing line winding machine 100, or may be a value set by the control means based on the size of the small spool 45 (such as the diameter and width of the small spool 45) set by the operator, or the diameter and length of the fishing line 35 to be wound onto the small spool 45.

Specifically, when the fishing line 35 is at its thinnest (0.2), the "predetermined value" is set to 5g, and the actual tension is 5g at the start of winding and 5g at the end of winding. When the fishing line 35 is at its thickest (30), the set value is 190g, and the actual tension is 200g at the start of winding and 180g at the end of winding. In other words, by setting the "predetermined value" of tension between 5g and 190g, the fishing line winding machine 100 of this embodiment can wind the fishing line 35 onto the small spool 45 at a tension between 5g and 200g.

In this way, the control means sets a "predetermined value" based on the size of the small spool 45 (such as the diameter and width of the small spool 45) set by the operator and the diameter and length of the fishing line 35 to be wound onto the small spool 45, and automatically adjusts the tension of the fishing line 35 during winding. This allows even someone unfamiliar with operating the fishing line winding machine 100 to wind the fishing line 35 onto the small spool 45 with the same quality as an experienced operator.

A pulley 65a is disposed between the fishing line supply mechanism 40 and the winding amount measurement mechanism 60, and a tension adjustment means 80 is provided between the fishing line supply mechanism 40 and the pulley 65a. Four pulleys 65b, 65c, 65d, and 65e are disposed in this order between the winding amount measurement mechanism 60 and the fishing line winding mechanism 50, and a tension detection means 70 is provided between two pulleys 65c and 65d.

The fishing line 35 wound around the large spool 30 is passed through the tension adjustment means 80, pulley 65a, length measurement encoder 55, pulleys 65b and 65c, tension detection means 70, and pulleys 65d and 65e, in that order, before being secured to the small spool 45. Pushing the push switch on the fishing line winding machine 100 rotates the large spool 30 and small spool 45, and the fishing line 35 wound around the large spool 30 is wound onto the small spool 45. When the feed amount of the fishing line 35 measured by the length measurement encoder 55 reaches a predetermined value, i.e., when the fishing line 35 wound around the small spool 45 reaches a predetermined length, the motors rotating the large spool 30 and small spool 45 automatically stop, and winding of the fishing line 35 onto the small spool 45 is completed. The small spool 45 with the fishing line 35 wound on it is cut nearby and removed from the fishing line winding mechanism 50, after which it is packaged, labeled, etc., and packed in small boxes in units of several units for shipping.

The fishing line winding machine 100 of this embodiment further includes a distance sensor 110 incorporating a laser light-emitting element and a light-receiving element, which is located on the side of the large spool 30, which is detachably attached to the fishing line supply mechanism 40, perpendicular to the rotation axis. The laser light emitted from the laser light-emitting element is reflected by the fishing line 35 wound on the large spool 30 and received by the light-receiving element. The reflected laser light is then evaluated and calculated, converted into a distance, and output. This allows the winding thickness of the fishing line 35 wound on the large spool 30 to be determined, and the feed speed of the fishing line 35 from the large spool 30 to be calculated from the change in the winding thickness of the fishing line 35 over time.
The fishing line winding machine 100 of this embodiment also includes a laser projector 20a and a light receiver 20b that are arranged opposite each other in a direction perpendicular to the rotation axis of a small spool 45 that is detachably attached to the fishing line winding mechanism 50. The laser light emitted from the laser projector 20a is blocked by the thickness of the fishing line 35 wound on the small spool 45. When the laser light is blocked in this manner, the amount of laser light that enters the light receiver 20b decreases, and this decrease in the amount of incident laser light indicates the thickness of the fishing line 35 wound on the small spool 45. From the change in the thickness of the fishing line 35 over time, the winding speed of the fishing line 35 onto the small spool 45 can be calculated.

A signal corresponding to the feeding speed of the fishing line 35 from the large spool 30 and a signal corresponding to the winding speed of the fishing line 35 onto the small spool 45 are sent to the control means that controls the fishing line winding machine 100, and the control means controls the motors that rotate the large spool 30 and the small spool 45 so that they operate synchronously. As a result, the rotation of the large spool 30 and the small spool 45 can be accelerated during winding, allowing the fishing line 35 to be wound at high speed from the start. Furthermore, because the feeding speed of the fishing line 35 from the large spool 30 and the winding speed of the fishing line 35 onto the small spool 45 can be made the same at any winding position, it is possible to prevent uneven winding when reeling in more line.
The laser projector 20a and the photodetector 20b are also capable of detecting the width between the flanges 45a of the small spool 45 attached to the fishing line winding mechanism 50. A signal corresponding to the width between the flanges 45a of the small spool 45 is sent to the control means that controls the fishing line winding machine 100, and the control means controls the reciprocating width of the tip of the suction head 5 of the fishing line winding mechanism 50 so that it matches the width between the flanges 45a of the small spool 45. As a result, there is no need to input the size of the small spool 45 when winding the fishing line 35, making it possible to wind the fishing line 35 more efficiently.

Between the pulley 65e and the fishing line winding mechanism 50 is provided fishing line holding means 90 for holding the fishing line 35. The fishing line holding means 90 is composed of a stay 95a whose base end is fixed to the frame of the fishing line winding machine 100, and a pair of fishing line holding rollers 95b rotatably attached to the tip of the stay 95a and which hold the fishing line 35 supplied from the fishing line supply mechanism 40. The opposing surfaces of the pair of fishing line holding rollers 95b are made of a flexible material such as semi-hard sponge or felt so as not to damage the fishing line 35.
With this configuration, when the fishing line 35 has been wound onto the small spool 45 and the small spool 45 needs to be replaced, the fishing line 35 can be cut between the fishing line holding means 90 and the small spool 45, so that the tip of the fishing line 35 supplied from the fishing line supply mechanism 40 can be held by the fishing line holding means 90, allowing the fishing line 35 to be immediately secured to the replaced small spool 45. As a result, the fishing line 35 can be wound up efficiently.

The fishing line winding machine 100 of this embodiment further includes a fishing line presser 25 located below the small spool 45 that is detachably attached to the fishing line winding mechanism 50, and that presses down the fishing line 35 being wound onto the small spool 45. The presser member 25b is a generally rectangular parallelepiped felt member having a length that is approximately the same as the width between the flanges 45a, 45a of the small spool 45, so as not to damage the fishing line 35.
However, some small spools have a tapered shape where the inner surfaces of both flanges gradually widen toward the outer periphery. If you try to wind fishing line evenly onto a small spool with such a shape, there is a risk that the line will become out of alignment.
In contrast, the configuration of the fishing line winding machine 100 of this embodiment is provided with a fishing line holding means 25 that holds down the fishing line 35 being wound onto the small spool 45, making it possible to neatly wind the fishing line 35 without disrupting its alignment.
In addition, a silicon applying means 27 is provided on the side of the fishing line pressing means 25 to apply silicon to the felt pressing member 25b in order to reduce friction between the felt pressing member 25b and the fishing line 35.

[Configuration of fishing line winding mechanism]
Next, the specific configuration of the fishing line winding mechanism, which is a component of the fishing line winding machine according to one embodiment of the present invention, will be described with reference to FIGS.

As shown in Figures 1 and 2, the fishing line winding mechanism 50 comprises a suction device 1 fixed to the frame of the fishing line winding machine 100, a cylindrical suction jig 2 that is removably attached to the suction device 1 and that sucks and holds the small spool 45 by vacuum suction from the suction device 1, and a shaft core 3 that is removably attached to the tip surface of the suction jig 2 and through which the barrel (not shown) of the small spool 45 is inserted when sucking and holding the small spool 45 to the suction jig 2. The shaft core 3 is made of highly corrosion-resistant stainless steel (such as SUS304), and its surface is mirror-polished.

The suction device 1 comprises a cylindrical main body 4 and a generally cylindrical suction head 5 rotatably supported within the main body 4 by bearings and having a suction hole (not shown) formed along its central axis. A driven pulley 6 is fixed to the rear end of the suction head 5. A motor 7 having a drive pulley 8 is installed above the suction device 1. A timing belt 9 is stretched between the driven pulley 6 and the drive pulley 8, and driving the motor 7 rotates the suction head 5 around its central axis. A suction pipe 10 connected to a vacuum pump 26 is connected to the rear end of the suction head 5 without interfering with the rotation of the suction head 5. The vacuum suction of the vacuum pump 26 can be turned on and off by pressing a foot pedal switch (not shown). That is, pressing the foot pedal switch turns on the vacuum suction of the vacuum pump 26, and pressing the foot pedal switch again turns off the vacuum suction of the vacuum pump 26. The suction device 1 is made of highly corrosion-resistant stainless steel (such as SUS304), and its surface is mirror-polished.

The suction jig 2 is fixed by screws to the tip surface of the suction head 5. Four suction holes 2a are formed at 90° intervals on a predetermined circumference of the suction jig 2. When the suction jig 2 is attached to the suction device 1, the four suction holes 2a are connected to the suction holes of the suction head 5.
Two annular ridges 2b, 2c are formed on the tip surface of the suction jig 2, sandwiching four suction holes 2a arranged on a predetermined circumference. Therefore, by abutting the flange 45a of the small spool 45 against the two ridges 2b, 2c, the space between the two ridges 2b, 2c can be sealed. Therefore, by turning on the vacuum suction of the vacuum pump 26 in this state, the small spool 45 can be sucked and held to the tip surface of the suction jig 2.

The suction head 5 is supported so that its tip can move back and forth along its central axis (see double-headed arrow M in Figure 2). In this case, the reciprocating movement of the tip of the suction head 5 is achieved using a cam mechanism (not shown) and a cam motor (not shown) provided within the device body 4. The cam motor is driven and rotated by pushing a push switch on the fishing line winding machine 100, which activates the cam mechanism and causes the tip of the suction head 5 to move back and forth along the central axis. The cam motor is also designed to automatically stop when the fishing line 35 wound onto the small spool 45 reaches a predetermined length. The movement of the tip of the suction head 5 is controlled according to the width of the small spool 45.
In this way, the fishing line 35 being wound up is not traversed, but rather the tip of the suction head 5, i.e., the suction jig 2, moves back and forth along the central axis of the small spool 45 that is held by suction (see the double-headed arrow N in Figure 2), thereby reducing the burden on the fishing line 35 during winding. As a result, the fishing line 35 wound onto the small spool 45 is less likely to develop a curl, improving the quality of the fishing line 35. Furthermore, since the fishing line 35 can be wound onto the small spool 45 in a direction perpendicular to the central axis (axis of rotation) of the small spool 45, it is easier to wind the fishing line 35 neatly and evenly.

[Configuration of tension detection means and tension adjustment means]
Next, the specific configurations of the tension detecting means and tension adjusting means, which are components of the fishing line winding machine of this embodiment, will be described with reference to FIG. 1 as well as FIGS. 3, 4 and 5.

Figure 3 is an enlarged front view illustrating the operation of the tension detection means, a component of the fishing line winding machine in one embodiment of the present invention; Figure 4 is an enlarged plan view showing the general configuration of the tension adjustment means, a component of the fishing line winding machine; and Figure 5 is an enlarged front view illustrating the operation of the tension adjustment means, a component of the fishing line winding machine.

As described above, the tension detection means 70 is provided between the two pulleys 65c and 65d.
1 and 3, the tension detection means 70 includes a pair of fixed pulleys 70a, 70b and a movable pulley 70c that is disposed between the fixed pulleys 70a, 70b and is movable up and down. The fishing line 35 that is let out via pulley 65c is wound around the upper part of fixed pulley 70a, the lower part of movable pulley 70c, and the upper part of fixed pulley 70b in that order, before passing through pulleys 65d and 65e and fishing line holding roller 95b and being attached to the small spool 45.
When the tension of the fishing line 35 during reeling exceeds a predetermined value, the fishing line 35, which is wound around the upper part of the fixed pulley 70a, the lower part of the movable pulley 70c, and the upper part of the fixed pulley 70b in that order, is pulled outward to the left and right (see arrows A and B in Figure 3), causing the movable pulley 70c to move upward (see arrow C in Figure 3).
On the other hand, if the tension of the fishing line 35 during winding falls below a predetermined value, the fishing line 35, which is wound around the upper part of the fixed pulley 70a, the lower part of the movable pulley 70c, and the upper part of the fixed pulley 70b in that order, will loosen inward to the left and right (see arrows D and E in Figure 3), and the movable pulley 70c will move downward (see arrow F in Figure 3).
A signal corresponding to the up and down movement of the moving pulley 70c is sent to a control means that controls the fishing line winding machine 100, and the control means controls a forward/reverse rotation motor 80f (described later) of the tension adjusting means 80.

As described above, the tension adjusting means 80 is provided between the fishing line supplying mechanism 40 and the pulley 65a.
As shown in Figures 1, 4 and 5, the tension adjustment means 80 includes a guide pulley (dancer roll) 80b that can move left and right along a horizontal elongated hole 80a located above the fishing line supply mechanism 40, a support arm 80c whose lower end rotatably supports the guide pulley 80b, a timing belt 80e that is stretched horizontally between a drive pulley (not shown) and a driven pulley 80d and to which the upper end of the support arm 80c is fixed, and a forward/reverse motor 80f that drives the drive pulley.
The tension adjusting means 80 further includes a first auxiliary pulley 80g fixed to the end of the movement path (long hole 80a) of the guide pulley (dancer roll) 80b in the direction in which the tension is released (to the right in Figures 1, 4, and 5).
The guide pulley 80b has three pulleys 80b-1, 80b-2, and 80b-3 arranged at equal intervals from the outside to the inside along the axial direction, while the first auxiliary pulley 80g has two pulleys 80g-1 and 80g-2 arranged from the outside to the inside along the axial direction.

In addition, a second auxiliary pulley 15 is fixed between the fishing line supply mechanism 40 and the tension adjustment means 80, positioned on the side of the movement path (long hole 80a) of the guide pulley (dancer roll) 80b in the direction in which tension is released (to the right in Figures 1, 4, and 5). The second auxiliary pulley 15 guides the fishing line 35 unwound from the large spool 30 of the fishing line supply mechanism 40 to the guide pulley 80b.

The fishing line 35 unwound from the large spool 30 is hooked around the second auxiliary pulley 15, then looped around the inner pulley 80b-3 of the guide pulley 80b, the inner pulley 80g-2 of the first auxiliary pulley 80g, the middle pulley 80b-2 of the guide pulley 80b, the outer pulley 80g-1 of the first auxiliary pulley 80g, and the outer pulley 80b-1 of the guide pulley 80b, before passing through pulley 65a and the length measuring encoder 55 of the winding amount measuring mechanism 60, before being attached to the small spool 45.

When the tension of the fishing line 35 during reeling exceeds a predetermined value and the movable pulley 70c moves upward (see arrow C in FIG. 3 ), a corresponding signal is sent to the control means, which in turn controls the forward/reverse motor 80f to rotate in the reverse direction. This causes the timing belt 80e to rotate counterclockwise in FIG. 5 (see arrows V1 and W1 in FIG. 5 ), and the guide pulley (dancer roll) 80b to move rightward via the support arm 80c (see arrow X1 in FIG. 5 ). The fishing line 35, which is looped around the upper portion of the fixed pulley 70a, the lower portion of the movable pulley 70c, and the upper portion of the fixed pulley 70b in that order, loosens inward to the left and right (see arrows D and E in FIG. 3 ), causing the movable pulley 70c to move downward (see arrow F in FIG. 3 ). That is, in this case, the guide pulley 80b moves horizontally in a direction that loosens the tension of the fishing line 35. As a result, the tension of the fishing line 35 during reeling is maintained at a predetermined value.
On the other hand, if the tension of the fishing line 35 during reeling falls below a predetermined value and the movable pulley 70c moves downward (see arrow F in FIG. 3 ), a corresponding signal is sent to the control means, which in turn controls the forward/reverse motor 80f to rotate forward. This causes the timing belt 80e to rotate clockwise in FIG. 5 (see arrows V2 and W2 in FIG. 5 ), and the guide pulley (dancer roll) 80b to move leftward via the support arm 80c (see arrow X2 in FIG. 5 ). The fishing line 35, which is looped around the upper portion of the fixed pulley 70a, the lower portion of the movable pulley 70c, and the upper portion of the fixed pulley 70b in that order, is pulled outward to the left and right (see arrows A and B in FIG. 3 ), causing the movable pulley 70c to move upward (see arrow C in FIG. 3 ). That is, in this case, the guide pulley 80b moves horizontally in a direction that increases the tension of the fishing line 35. As a result, the tension of the fishing line 35 during reeling is maintained at a predetermined value.

By configuring the tension adjusting means 80 as described above, the tension of the fishing line 35 can be adjusted to an appropriate value at any time without exerting a pressing force on the fishing line 35 (while minimizing the load on the fishing line 35).
Furthermore, by adjusting the tension of the fishing line 35 by horizontally moving the guide pulley (dancer roll) 80b, it is possible to reduce the height of the fishing line winding machine 100 while increasing the adjustment margin for the tension of the fishing line 35. Furthermore, since the tension of the fishing line 35 can be stably adjusted without being affected by external factors such as gravity, it is easier to maintain a constant tension on the fishing line 35. As a result, the fishing line 35 can be neatly wound.

Furthermore, in this embodiment, the tension adjustment means 80 includes a horizontally movable guide pulley 80b around which the fishing line 35 unwound from the large spool 30 is hooked, and a first auxiliary pulley 80g fixed to the end of the guide pulley 80b's movement path (long hole 80a) in the direction of tension release, around which the fishing line 35 unwound from the guide pulley 80b is hooked and which returns the fishing line 35 to the guide pulley 80b. This allows the fishing line 35 unwound from the large spool 30 to be looped back between the guide pulley 80b and the first auxiliary pulley 80g. As a result, compared to the case of Patent Document 2, it is possible to adjust the tension of the fishing line 35 over a larger range with a smaller movement of the guide pulley 80b (greater adjustment range for the fishing line 35). Furthermore, because the horizontal movement of the guide pulley 80b can be reduced as described above, the fishing line winding machine 100 can be made smaller in size in the lateral direction.
Therefore, the configuration of the fishing line winding machine 100 of this embodiment makes it possible to provide a fishing line winding machine that is further miniaturized while allowing for greater adjustment of the tension of the fishing line 35 .
Furthermore, in this embodiment, the guide pulley 80b has three pulleys 80b-1, 80b-2, and 80b-3 arranged at equal intervals from the outside to the inside along the axial direction, and the first auxiliary pulley 80g has two pulleys 80g-1 and 80g-2 arranged from the outside to the inside along the axial direction, so that the fishing line 35 that is let out from the large spool 30 can be folded back multiple times between the guide pulley 80b and the first auxiliary pulley 80g. As a result, it is possible to adjust the tension of the fishing line 35 over a larger range (further increasing the adjustment range for the tension of the fishing line 35) with a smaller movement of the guide pulley 80b.

In addition, in this embodiment, the second auxiliary pulley 15 that guides the fishing line 35 being let out from the large spool 30 to the guide pulley 80b is fixed to the side of the movement path (long hole 80a) of the guide pulley (dancer roll) 80b between the large spool 30 and the tension adjustment means 80 that loosens the tension.This makes it possible to maintain a constant support portion for the fishing line 35 guided by the guide pulley 80b regardless of the amount of fishing line 35 remaining on the large spool 30.As a result, uniform tension adjustment of the fishing line 35 is possible regardless of the amount of fishing line 35 remaining on the large spool 30.

In this embodiment, the tension adjustment means 80 includes a guide pulley 80b that can move left and right along a horizontal slot 80a located above the fishing line supply mechanism 40 and around which the fishing line 35 unwound from the large spool 30 of the fishing line supply mechanism 40 is hooked; a first auxiliary pulley 80g that is fixed to the end of the guide pulley 80b's travel path (slot 80a) that releases tension and around which the fishing line 35 unwound from the guide pulley 80b is hooked and returns the fishing line 35 to the guide pulley 80b; a support arm 80c whose lower end rotatably supports the guide pulley 80b; a timing belt 80e that is hung horizontally between a drive pulley and a driven pulley 80d and to which the upper end of the support arm 80c is fixed; and a forward/reverse motor 80f that drives the drive pulley. However, the present invention is not necessarily limited to this configuration. The tension adjustment means may include a horizontally movable guide pulley onto which the fishing line unwound from the large spool is hooked, a first auxiliary pulley fixed to the end of the guide pulley's movement path in the direction in which the tension is released, onto which the fishing line unwound from the guide pulley is hooked and which loops the fishing line back onto the guide pulley, and a drive mechanism for horizontally moving the guide pulley; the configuration of the drive mechanism is optional.

In addition, in this embodiment, the tension detection means 70 is described as having a pair of left and right fixed pulleys 70a, 70b and a movable pulley 70c that is positioned between the left and right fixed pulleys 70a, 70b and is movable up and down, with the fishing line 35 being looped around the upper part of the fixed pulley 70a, the lower part of the movable pulley 70c, and the upper part of the fixed pulley 70b in that order. However, the present invention is not necessarily limited to this configuration. The fishing line 35 may also be looped around the lower part of the fixed pulley 70a, the upper part of the movable pulley 70c, and the lower part of the fixed pulley 70b in that order. Furthermore, tension detection means with other configurations can also be used, and the configuration of the tension detection means is arbitrary.

Furthermore, in this embodiment, an example has been described in which the guide pulley 80b has three pulleys 80b-1, 80b-2, and 80b-3 arranged at equal intervals from the outside to the inside along the axial direction, and the first auxiliary pulley 80g has two pulleys 80g-1 and 80g-2 arranged from the outside to the inside along the axial direction. However, the present invention is not necessarily limited to this configuration. The first auxiliary pulley may have one or more pulleys arranged in the axial direction, and the guide pulley may have two or more pulleys arranged in the axial direction, one more than the number of pulleys on the first auxiliary pulley.

In addition, in this embodiment, a second auxiliary pulley 15 is fixed to the side of the guide pulley 80b's movement path (long hole 80a) between the large spool 30 and the tension adjustment means 80, in the direction in which tension is released, to guide the fishing line 35 being let out from the large spool 30 to the guide pulley 80b. However, the present invention is not necessarily limited to this configuration. The provision of a second auxiliary pulley is optional.
