Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tension adjusting device in a rewinding machine for rewinding a fishing line such as nylon gut used for fishing from a large spool to a small spool.

[0002]

2. Description of the Related Art A conventional rewinding machine of this type has a structure as shown in FIGS. 4 and 5, for example. This is to rewind a fishing line (hereinafter referred to as a fishing line) wound around a large spool from a fiber manufacturer and rewound into a small spool which is suitable for a fishing tackler to market. The outline will be described. A supply spool 1 (a large spool) is installed on a feeding device 3, and a fishing line 4 fed out is a pulley 5.
The winding spool 2 (small spool) installed in the winding device 11 is wound up through a passage formed by 6, 7, 8, 9, and 10. The delivery device 3 includes a servo motor 12 and delivers the fishing line 4. Pulleys 5 and 7
Is a fixed pulley, and the pulley 6 between them is supported by a rotating arm 14 extending from the tension detector 13, and is biased by a spring so as to rotate the arm 14 downward.
Tension is applied to the fishing line 4 hung on 7. The tension detector 13 detects an increase / decrease in the tension because the angle of the arm 14 changes when the tension of the fishing line 4 applied to the pulley 6 changes. The rotation speed of the motor 12 is controlled by the control circuit based on the detection of the tension detector 13, so that the tension of the fishing line 4 during rewinding is maintained constant.

The take-up spool 2 is a large number of spools 2.
2n are coaxially and detachably connected. The take-up device 11 is provided with a take-up spool 2 and is provided with a servo motor 15, and is adapted to take up the fishing line 4 from the one end of the spool 2 in a predetermined length in order. The winding device 11 additionally has an axial feed mechanism that supports the pulleys 8, 9, 10 so as to supply the fishing line 4 to a predetermined spool 2. Although not shown in detail, for example, when winding the spool 2a, the pulleys 8, 9 and 10 are axially moved by a feed mechanism in which a screw rod is reversely driven at a constant rotation amount corresponding to a winding width of the spool 2a. It reciprocates and laps. In the figure, 16 is a reversible servomotor of the feeding mechanism. Reference numeral 17 denotes a panel of the control unit, which has a spool diameter, a winding width,
Various setting / display devices for winding length, thread diameter, supply spool diameter, switch buttons for operation, stop, emergency stop, reset, etc. are arranged.

A predetermined setting is made on the panel 17 of the controller to fix the starting end of the fishing line 4 to the spool 2a and start winding. When the fishing line 4 of a predetermined length is wound around the spool 2a, the line length detector detects it and the motors 12, 15, 1
6 are stopped all at once, and only the motor 16 is rotated to move the pulleys 8, 9, 10 to a position where the fishing line 4 is guided to the next spool 2b.
Position, the fishing line 4 is not cut and remains continuous between the adjacent spools, and the motors 12, 15, 16 rotate again to perform the winding operation. By repeating this, a series of fishing lines are wound on each of the spools 2 by a predetermined length.

[0005]

If the fishing line wound on the spool is wound too tightly, it will have a curling tendency, resulting in a decrease in commercial value. If it is wound too loosely, it will move in the spool width direction and become a part wound upward. Even if the upper and lower relations of the part wound on the lower side are interchanged, it may cause a hang. It has been found that there is a problem that a good winding state is not always obtained when rewinding by a conventional fishing line rewinding machine. The cause is that the tension of the fishing line during winding is not appropriate. In the conventional fishing line rewinding machine, the adjusting device for keeping the tension of the fishing line 4 during rewinding is configured to detect the change in the tension by the tension detector 13 and then correct the rotation speed of the motor 12. , The tension is changing and not constant. Since the fishing line is rewound at a high speed, the fishing line is partially wound on the spool, that is, a tightly wound portion and a loosely wound portion. Moreover, since the magnitude of the applied tension is adjusted by adjusting the spring force that urges the arm 14, it is difficult to keep the tension constant each time the tension is changed. An object of the present invention is to provide a device capable of easily adjusting the tension of the yarn when rewinding the yarn so that the tension of the yarn is always a set constant value.

[0006]

Means for Solving the Problem The means of the present invention is a tension adjusting device for a fishing line rewinder for winding a fishing line sent from a rotationally driven supply spool onto a rotationally driven take-up spool. In the middle of the fishing line passage leading to the take-up spool, a moving pulley that is movable up and down so as to give a predetermined tension to the fishing line by gravity is interposed, and position detecting means for detecting the height of the moving pulley with respect to a predetermined reference height position is provided, Based on the detection by the position detection means, the rotational speed of one of the supply spool and the take-up spool is increased / decreased so that the moving pulley returns to the reference height position.

In the above means, the moving pulley is provided so as to be guided up and down by a linear guide, and the position detecting means is a detected portion integrally provided on the moving pulley, and the detected portion. It is preferable that a plurality of non-contact type detectors are arranged along the straight line guide so as to detect the position of the moving pulley based on the position. Further, it is preferable that the rotation driving unit of the one spool is composed of a pulse motor. Further, it is preferable that the detector is a light source and a light receiving element, and the detected portion is a light shielding plate. Further, it is preferable that the moving pulley is provided with a weight attaching means so that the weight can be added and removed.

[0008]

According to the above-mentioned means, the tension applied to the fishing line at the time of rewinding is determined by the weight of the moving pulley side, so that it is always constant. The change in the feed-out speed of the supply spool and the take-up speed of the take-up spool, that is, the change in the running speed of the fishing line due to the change in the diameter of the wound part, is caused by the vertical displacement of the moving pulley regardless of the tension. Then, this is detected by the position detection means, and the moving pulley returns to the reference height position by increasing or decreasing the rotation speed of one of the supply spool and the take-up spool based on this detection. The rewound state can be continued. Therefore, although the moving pulley is displaced, the tension is still constant, and rewinding is performed with the tension being completely constant.

The structure in which the moving pulley is guided by the linear guide is
The swing of the moving pulley is prevented, and the position of the moving pulley is surely detected by the position detecting means. The non-contact type detector does not affect the tension. The configuration using the pulse motor has a quick response, and the moving range of the moving pulley can be narrowed. The configuration of the light source, the light receiving element, and the light shielding plate is highly reliable, operates reliably, and is a non-contact type. Further, if the moving pulley can add and remove the weight, the magnitude of the tension can be easily changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. This tension adjusting device is applied in place of the pulleys 5, 6, 7 of the above-described conventional fishing line rewinding machine (see FIGS. 4 and 5), the tension detector 13, and the like. Pulleys 20, 21, 22, 23 corresponding to 6 and 7, linear guide device 24, position detecting means 25, weight attaching means 2
It has 6 mag. Pulleys 20, 21, and 23 are fixed pulleys, and are attached to upper members 31 fixed to columns 30 standing upright from the base of the fishing line rewinder via brackets. The pulley 22 is a movable pulley that is supported by the fishing line 4 and is vertically movable by a guide device 24.

The linear guide device 24 is a linear motion ball bearing type having a very small frictional resistance, and since it is generally commercially available, a detailed illustration is omitted. It is composed of a linear guide 32 having a constant cross section having two moving grooves, and a movable part 33 holding the ball inside a member having a U-shaped cross section extending over both side surfaces of the linear guide 32 at a predetermined length. , This movable part 3
The bracket 39 is fixed to 3, and the movable pulley 22 is attached to this. In the figure, 34 is a linear guide mounting portion for the column 30.
It is fixed to. The position detecting means 25 is composed of a detector and a detected part. The detector is provided with a light source 35 and a light receiving element 36 with a small gap therebetween, and a plurality of such detectors, for example, five detectors, are arranged on a bracket 38 fixed to the linear guide mounting portion 34 at predetermined intervals in the vertical direction. The part to be detected is a light shielding plate 37, which is attached to a bracket 39 to which the moving pulley 22 is attached, has a vertical dimension corresponding to the arrangement pitch of the detectors, and has a small gap between the light source and the light receiving element of the detector. The movable pulley 22 has a thickness that allows the movable pulley 22 to pass therethrough without coming into contact with it. With this configuration, when the moving pulley 22 moves up and down, the position is always detected by one of the detectors.

The weight attaching means 26 is such that the weight 41 can be attached to and removed from the bracket 39 to which the moving pulley 22 is attached by the screw 40. Depending on the type of fishing line 4 to be rewound, the weight 41 is added in advance to the weight on the side of the movable pulley 22 to obtain an optimum weight, that is, an optimum tension is generated on the fishing line 4, and different weights are previously set. Be prepared. In addition to the above, this tension adjusting device detects a predetermined detector by the height position detection signal of the moving pulley 22 obtained from the position detecting means 25, for example, by using the middle detector in the vertical arrangement as a reference. When it is detected that the movable pulley 22 has moved to the upper side based on the height position, the motor 12 is controlled so that the rotation speed of the large spool 1 is increased, and the movable pulley 22 is moved to the lower side. When the movement is detected, the motor 12 is controlled so that the rotation speed of the large spool 1 is slowed down so that the moving pulley is returned to the reference position. Also,
The motor 12 is a pulse motor.

The fishing line rewinding machine equipped with this tension detecting device is used in the same manner as the conventional one, but the tension of the line at the time of winding is set by adding and removing the weight 41. Large spool 1
The fishing line 4 pulled out from the pulleys 20, 21, 22, 23
Then, the yarn end is fixed to the end 2a of the small spool 2 via the pulleys 8, 9 and 10, and the operation is started.
Since the tension of the fishing line 4 during winding is set by weight, the moving pulley 22 is rewound even if it is returned to the original reference position by controlling the speed of the motor 12 while moving upward or downward. Since the tension of the fishing line 4 therein is not affected, the rewinding is always performed under the set constant tension. Therefore, as a result of being able to give the optimum tension to the fishing line 4, the fishing line 4 is rewound in an extremely good state. Since the optimum tension can be prepared in advance with a weight corresponding to the type of fishing line 4, the operation can be performed easily and reliably.

In the above embodiment, the position detecting means 25
Shows a device composed of a photoelectric detector and a detected part formed of a light shielding plate, but instead of this, a plurality of proximity switches arranged vertically along the linear guide 32 and provided on the movable pulley side. Alternatively, a permanent magnet may be used. Further, the drive motor 12 of the large spool 1 (supply spool) is a pulse motor, and the rotation speed is adjusted based on the detection by the position detecting means 25. Instead of this, the small spool 2 (rewind spool) It is also possible to use the drive motor 15 as a pulse motor and adjust the rotation speed based on the detection by the position detection means 25.

[0015]

According to the first aspect of the present invention, since the rewinding is performed in a state where the tension is completely constant, the fishing line wound on the winding side spool is held in a fixed state.
By determining the weight of the moving pulley side so that the tension will be optimum, a spool-wound fishing line that is very well wound and has a high commercial value can be obtained. According to the invention of claim 2,
Since the position of the moving pulley is surely detected and the tension is not affected, the tension adjusting device has high reliability. Claim 3
According to the invention described in (1), since the moving range of the moving pulley can be narrowed, a compact structure can be achieved. According to the invention described in claim 4, since the operation is reliable, the tension adjusting device is highly reliable. According to the invention described in claim 5, since the magnitude of the tension can be easily changed, the operation is simple, and the optimum tension can be surely applied, so that different types of yarn can be rewound. Even when performing a setup change, the optimum tension for the fishing line can be reliably applied by a simple operation of changing the weight.
