Description

The present invention relates to a winding device for winding a cord-like member to be wound, such as a cable. In particular, the present invention relates to a winding device that winds members to be wound in parallel.

BACKGROUND ART Conventionally, the fleet angle has been reduced in order to wind the members to be wound around a drum in parallel, that is, to wind the members to be wound in alignment on the drum. The fleet angle refers to the angle formed by a line connecting the drum and the center of the introduction hole that guides the material to be wound onto the drum, and a line connecting the inside of the end of the drum and the center of the introduction hole. If the fleet angle is large, even if an attempt is made to wind the material to be wound around the end of the drum, the force of the material trying to return to the center will be large, and the material will not be wound in parallel, but wound in a hump near the center. On the other hand, if an attempt is made to reduce the fleet angle while keeping the width of the drum the same, the distance between the drum and the introduction hole becomes longer, and the winding device becomes larger as a whole. This problem is particularly noticeable in winding devices whose dustproof and waterproof properties are improved by installing an introduction hole in a case and storing a drum therein.

Therefore, a winding device has been proposed that includes a half-ring-shaped swinging member that is arranged along the circumferential direction of the drum and swings around an axis perpendicular to the axis of the drum (see Patent Document 1). In this winding device, the material to be wound is guided from an introduction hole to the center of a semi-ring-shaped swinging member and wound around a drum, and the swinging member is provided with a biasing means to urge it to return to the center. . When the drum rotates and the member to be wound moves toward one flange, the swinging member tends to fall toward the flange due to the tension of the member to be wound. However, by suppressing the falling of the material using the biasing means, the swinging member can follow the movement of the material to be wound along the entire surface of the drum without resistance. Can be wound in parallel.

With this configuration, the above-described winding device allows the introduction hole and the drum to be positioned close to each other. However, it is necessary to change the spring coefficient of the biasing means depending on the tension of the member to be wound up. It is normal for the tension of the member to be wound to fluctuate, and there is room for improvement for practical use.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a winding device that has a simple structure, allows an introduction hole to be brought close to a drum, and winds a member to be wound in parallel regardless of the tension of the member to be wound. The task is to

In order to solve the above problems, a winding device according to a first aspect of the present invention has an introduction hole 100 into which a string-shaped member to be wound 90 is introduced, as shown in FIGS. 1 and 2, for example. A winding device 10 for a member 90 to be wound, comprising a drum 20 having flanges 24 and 26 at both axial ends of a drum 22 and rotatable around an axis 28 of the drum 22, and a drive for rotating the drum 20. a first guide portion 40 for introducing a material to be wound 90 along a first axis 48 disposed in a torsional relationship substantially perpendicular to the axis 28 of the cylinder; It has a movable swinging member 60 and a second guide part 50 that is attached to the tip of the swinging member 60 and guides the wound member 90 from the first guide part 40 to the drum 20. The part 50 is attached to the swinging member 60 so that the member to be wound 92 of the winding part wound onto the drum 20 from the second guide part 50 is approximately parallel to the first axis 48. is wound around the drum 20 via the first guide section 40 and the second guide section 50.

With this configuration, the member to be wound guided through the introduction hole along the first axis which is substantially perpendicular to the axis of the cylinder and arranged in a torsional relationship is attached to the first guide part and the swinging member. The second guide section causes the member to be wound up on the drum from the second guide section to be wound up substantially parallel to the first axis. Therefore, even if the tension becomes large, the direction of the tension and the direction in which the swinging member swings are perpendicular to each other, so that the swinging member can easily swing. That is, the member to be wound up in the winding section that is wound around the drum is likely to move in the width direction of the drum. Since the member to be wound up is wound around the drum, the member to be wound up is wound on the drum in parallel winding while being pushed along the member to be wound up. Therefore, there is provided a winding device that has a simple structure, can make the entire device compact by arranging the introduction hole at a position close to the drum, and can wind the material to be wound in parallel.

In the winding device according to the second aspect of the present invention, for example, as shown in FIG. 1, the second guide section 50 includes a second pulley 52 supported by a swinging member 60. With this configuration, the second guide part includes a pulley, and as the swinging member swings, the second guide part moves in the width direction of the drum, so the structure is simple, and since the pulley is used, the second guide part moves in the width direction of the drum. It can be guided to the drum with little resistance.

In the winding device according to the third aspect of the present invention, for example, as shown in FIG. 1, the first guide section 40 includes a first pulley 42 supported by a swinging member 60. With this configuration, the first pulley of the first guide part and the second pulley of the second guide part are supported by the swinging member that swings around the first axis, so the structure can be simplified. and can be guided to the drum with little resistance.

In the winding device according to the fourth aspect of the present invention, for example, as shown in FIG. 2, the swinging member 60 has a balance weight 62 on the opposite side of the second guide portion 50 with respect to the first axis 48. With this configuration, since the swinging member has a balance weight on the opposite side of the second guide part, the center of gravity of the swinging member moves close to the first axis, and the weight generated at the position of the first axis moves. The moment can be reduced, and the swinging member can easily swing around the first axis.

In the winding device according to the fifth aspect of the present invention, for example, as shown in FIG. The member 90 to be wound is wound around more than half the circumference of the first pulley 44, and the rotation axis 46 of the first pulley 44 is inclined with respect to the axis 28 of the barrel. With this configuration, since the first pulley is located on the opposite side of the second guide with respect to the first axis, the center of gravity of the swinging member moves close to the first axis and is at the position of the first axis. It is possible to reduce the moment due to the generated own weight, etc., and it is easy to swing around the first axis. Furthermore, since the rotation axis of the first pulley is inclined with respect to the axis of the barrel, it is possible to avoid the members to be wound from intersecting each other.

In the winding device according to the sixth aspect of the present invention, for example, as shown in FIG. and a third pulley 74 supported by the swinging member 60, and the member 90 to be wound is sent to the second pulley 52 via the first pulley 70 and the third pulley 74. With this configuration, since the first pulley and the third pulley are located on the opposite side of the second guide section with respect to the first axis, the center of gravity of the swinging member moves near the first axis and the first pulley moves toward the first axis. It is possible to reduce the moment due to dead weight, etc. that occurs at the position of the axis, and it is easy to swing around the first axis.

According to the winding device of the present invention, the winding member guided along the first axis, which is substantially perpendicular to the axis of the barrel and arranged in a torsional relationship, is attached to the first guide portion and the swinging member. The second guide part causes the member to be wound up on the drum from the second guide part to be wound up approximately parallel to the first axis, and the member to be wound is wound in parallel and wound on the drum. It will be done. Therefore, it is possible to provide a winding device that has a simple structure, allows the introduction hole to be placed close to the drum, makes the entire device compact, and winds the material to be wound in parallel. In particular, in a winding device that has improved dustproof and waterproof properties by attaching an introduction hole to the case and storing a drum or the like therein, the effect is more significant because the case can be made more compact.

FIG. 2 is a perspective view of the winding device shown in FIG. 1. The inside is shown through the case.

Embodiments of the present invention will be described below with reference to the drawings. In each figure, devices that are the same or correspond to each other are given the same reference numerals, and duplicate explanations will be omitted.

First, with reference to FIGS. 1 and 2, a winding device 10 as an embodiment of the present invention will be described. The winding device 10 includes a drum 20 for winding a string-shaped member to be wound 90, a drive source 30 for rotating the drum 20, a first guide portion 40 for introducing the member to be wound 90, and a drum for winding the string-like member to be wound. It has a second guide part 50 for guiding the taking member 90 to the drum 20. The winding device 10 also includes a case 110 that encloses these devices and has an introduction hole 100 into which the winding member 90 is introduced. The string-shaped member to be wound 90 may be, for example, a power line or a communication cable, and is not particularly limited.

The drum 20 has flanges 24 and 26 at both axial ends of the drum 22, and is rotatably held around an axis 28 of the drum 22. Although the barrel 22 has a cylindrical shape in this embodiment, its shape is not particularly limited as long as the member to be wound 90 can be wound around it. As the drum 20 rotates around the axis 28, the member 90 to be wound is wound around the drum 22. The flanges 24 and 26 are members that extend in the radial direction of the shell 22 to prevent the member 90 to be wound up from coming off the shell 22. The flanges 24 and 26 are formed, for example, in the shape of a disk, but may be formed of a plurality of rod members or the like. may be done.

The drum 20 is rotated around an axis 28 by a drive source 30. The drive source 30 may be a known device such as a motor and a speed reducer, a motor and a chain and sprocket, a motor and a belt and a pulley. The motor is not limited to an electric motor, and may be of a hydraulic or water pressure drive type, or may obtain rotational power from an engine. The method of connecting the drum 20 and the drive source 30 is not particularly limited.

The first guide section 40 introduces the member to be wound 90 along a first axis 48 that is substantially perpendicular to the axis 28 of the barrel and arranged in a torsional relationship. Here, the torsional relationship means that the first axis 48 does not intersect with the axis 28 of the drum, that is, the member 90 to be wound is not directly wound on the drum 20, but is From the guide part 40, the direction is bent by a second guide part 50, which will be described later, and the film is wound onto the drum 20. The fact that the first axis 48 is substantially perpendicular to the axis 28 of the barrel means that the member 90 to be wound is introduced from the substantially radial direction of the barrel 22, and does not need to be strictly perpendicular. In the present embodiment, the first guide section 40 includes a hole 49 formed in a swinging member 60 to introduce a wound member 90, which will be described later, and a first pulley 42. Ru. The member to be wound 90 is guided from the outside through an introduction hole 100 formed in the case 110 and guided to the first guide section 40 . A guide tube 41 (see FIG. 1) may be included to guide the member 90 to be wound up from the introduction hole 100 along the first axis 48. Note that the member 90 to be wound up is supported by other equipment (not shown) in the upper part of FIG. 1, or because of its own weight, tension is generated when the member 90 is wound up.

The second guide section 50 guides the member 90 to be wound up from the first guide section 40 to the drum 20. The second guide part 50 is located in a direction substantially perpendicular to the trunk axis 28 and the first axis 48 with respect to the first guide part 40 . Then, the member 90 to be wound up is arranged from the second guide portion 50 toward the barrel 22 at a position substantially perpendicular to the axis 28 of the barrel. That is, the member to be wound 90 is introduced along the first axis 48 which is substantially perpendicular to the axis 28 of the cylinder and arranged in a twisted relationship, and the member to be wound 90 is wound onto the drum from the second guide portion 50. The winding portion and the winding member 92 become substantially parallel. In this embodiment, the second guide section 50 is configured to include a second pulley 52.

The first pulley 42 of the first guide section 40 and the second pulley 52 of the second guide section 50 are rotatably supported by the swinging member 60. The swinging member 60 is supported so as to be swingable about the first axis 48 . The configuration for supporting the swinging member 60 is not particularly limited, and for example, it may be supported by a support pin (not shown) that is substantially coaxial with the first axis 48, or it may be supported by a support pin (not shown) that is substantially coaxial with the first axis 48 (see FIG. 1). ), as long as it is supported swingably. The second pulley 52 is arranged at the tip of the swinging member 60. Here, the "tip" refers to the distal part of the swinging member 60 from the first axis 48, and does not need to be strictly the end. As the swinging member 60 swings around the first axis 48, the second pulley 52 reciprocates on an arc centered on the first axis 48 across the width of the drum 20, that is, between the two flanges 24 and 26. The member 90 to be wound is wound in parallel around the body 22 of the drum 20. Note that it is sufficient that the second pulley 52 is supported not strictly around the first axis 48 but at a position where the second pulley 52 can substantially reciprocate in the width direction of the drum 20. Further, the member to be wound 90 between the first pulley 42 and the second pulley 52 is substantially perpendicular to the member to be wound 90 introduced along the first axis 48 and the member to be wound in the winding section 92. The swinging member 60 is arranged so as to form the following.

As shown in FIG. 2, a hole 49 may be formed in the swinging member 60 for introducing the member 90 to be wound up. However, the structure of the swinging member 60 only needs to rotatably support the first pulley 42 of the first guide section 40 and the second pulley 52 of the second guide section 50, and for example, the swing member 60 may be configured of a beam. It's okay. In that case, the hole 49 is not formed and the member 90 to be wound up may be introduced through between the beams.

As shown in FIG. 2, the swinging member 60 may include a balance weight 62 on the opposite side of the second guide portion 50 with the first axis 48 interposed therebetween. The balance weight 62 is a weight for canceling or reducing the moment around the first axis 48, that is, around the support point, which is caused by the weight of the swinging member 60 due to its length on the second guide portion 50 side. When the center of gravity of the swing member 60 moves away from the first axis 48 serving as the center of swing, the swing member 60 tilts and becomes difficult to swing. By bringing the center of gravity of the entire swinging member 60 closer to the first axis 48 using the balance weight 62, the attitude of the swinging member 60 can be adjusted by the weight of the swinging member 60, etc., no matter what attitude the winding device 10 is in. will no longer tilt. Therefore, the swinging member 60 follows the movement of the second guide portion 50 due to the winding of the member 90 around the drum 20 without resistance.

In the winding device 10, the member 90 to be wound up is guided to the first guide portion 40 along the first axis 48. The member to be wound 90 changes its direction at the first guide section 40 and is guided to the second guide section 50, changes its direction at the second guide section 50, and is wound onto the drum 20. Therefore, it is possible to bring the introduction hole 100 closer to the drum 20. According to the winding device 10 , when the drum 20 is rotated by the driving force of the drive source 30 , the member 90 to be wound up is pulled via the second pulley 52 . In the body 22 of the drum 20, the member 92 of the winding section to be wound comes into contact with the member 90 to be wound up that has been previously wound on the body 22 and slides, so that the member 92 to be wound up is not wound next to it in parallel. It is then wound up. At this time, since the swinging member 60 swings around the first axis 48, the second guide portion 50 moves in the width direction of the drum 20. By moving the second guide section 50 in the width direction of the drum 20, the winding section winding member 92 is easily wound in parallel. At that time, the member 92 to be wound in the winding section is approximately parallel to the first axis 48, and the member 90 to be wound in the winding portion is approximately perpendicular to the first pulley 42 to the second pulley 52 by the swinging member 60. Sent. Therefore, even if a large tension is generated in the member 90 to be wound up, the swinging direction of the swinging member 60 is perpendicular to the swinging direction of the swinging member 60, so that the swinging member 60 easily swings. "Substantially parallel" and "substantially perpendicular" here do not mean strictly "parallel" or "perpendicular", but rather, the terms "approximately parallel" and "approximately right angle" do not mean strictly "parallel" or "perpendicular", but rather, the terms "approximately parallel" and "approximately perpendicular" do not mean strictly "parallel" or "perpendicular"; It is used to indicate the direction in which the member to be wound 90 is arranged. In fact, when the winding device 10 winds up the material to be wound 90, the direction in which the material to be wound 90 is introduced (approximately parallel to the first axis 48) is also The member 90 also changes constantly. For example, the direction of the wound member 92 in the winding portion changes depending on the number of turns of the wound member 90 wound onto the body 22. Because of this situation, they are called "substantially parallel" and "substantially perpendicular."

Next, with reference to FIG. 3, a winding device 12 as an embodiment of the present invention will be described. The winding device 12 is configured such that the path of the member 90 to be wound is around the first pulley 44 of the first guide section 40 for more than half a turn, and that the path of the member 90 is sent to the first pulley 44 along the first axis 48. The first pulley 44 is inclined in order to avoid the intersection between the member 90 to be wound and the member 90 to be wound that is sent from the first pulley 44 to the second guide section 50. Although this device is different from the device 10, the rest is the same, so a duplicate explanation will be omitted. Note that in FIG. 3, the swinging member 60 is omitted.

In the winding device 12, the first pulley 44 of the first guide section 40 is arranged on the opposite side of the second guide section 50 with the first axis 48 interposed therebetween. Here, when the first pulley 44 is arranged on the opposite side of the second guide part 50 with the first axis 48 in between, the rotating shaft 46 of the first pulley 44 is arranged on the opposite side of the second guide part 50 with the first axis 48 in between. This means that it is disposed on the opposite side to the second guide section 50. Therefore, the moment caused by the weight on the second guide part 50 side around the first axis 48, which is the support point, and the moment due to the weight on the first guide part 40 side are canceled out or reduced. The same effect as the balance weight 62 described using FIG. 2 is produced, and the swinging member 60 becomes easier to swing around the support point.

Further, in the winding device 10, the axis 28 of the body 22 of the drum 20, the rotation axis 43 of the first pulley 42, and the rotation axis 54 of the second pulley 52 are substantially parallel. On the other hand, in the winding device 12, the rotating shaft 46 of the first pulley 44 is tilted, and the member 90 to be wound is sent to the first pulley 44 along the first axis 48, and the rotating shaft 46 of the first pulley 44 is Intersection with the member to be wound 90 sent to the second guide section 50 is avoided. That is, the rotation axis 46 of the first pulley 44 is inclined from the axis 28 of the barrel 22 . The direction of inclination may be an up-down direction, a horizontal direction (toward the second guide portion 50), or an oblique direction therebetween. The smaller the inclination angle T is, the smaller the resistance when winding up the member 90 to be wound up is, so it is preferable.

Next, with reference to FIG. 4, a winding device 14 as an embodiment of the present invention will be described. In the winding device 14, the first guide section 40 has a first pulley 70 and a third pulley 74, and the first pulley 70 and the third pulley 74 are arranged in the second guide section 50 with respect to the first axis 48. This differs from the winding devices 10 and 12 in that the winding member 90 is sent to the second pulley 52 via the first pulley 70 and the third pulley 74. Since the other details are the same, duplicate explanations will be omitted. Here, when the first pulley 70 and the third pulley 74 are arranged on the opposite side of the second guide part 50 with the first axis 48 in between, the rotation axis 72 of the first pulley 70 and the This means that the rotating shaft 76 of the pulley 74 of No. 3 is disposed on the opposite side of the second guide portion 50 with the first axis 48 interposed therebetween. Note that in FIG. 4, the swinging member 60 is omitted.

In the winding device 14, the first pulley 70 and the third pulley 74 of the first guide section 40 are arranged on the opposite side of the second guide section 50 with the first axis 48 interposed therebetween. Therefore, the moment caused by the weight on the second guide part 50 side around the first axis 48, which is the support point, and the moment due to the weight on the first guide part 40 side are canceled out or reduced. The same effect as the balance weight 62 described using FIG. 2 is produced, and the swinging member 60 becomes easier to swing around the support point. In addition, in the winding device 14, as is clear from FIG. The rotating shaft 72 of the first pulley 70 and the rotating shaft 76 of the third pulley 74 do not intersect with the winding member 90 sent to the It is substantially parallel to the axis 54.

As described above, the winding devices 10, 12, and 14 have a simple structure, and while making it possible to bring the introduction hole 100 close to the drum 20, the winding devices 10, 12, and 14 are not affected by the tension of the material to be wound 90, etc. The member to be wound 90 can be wound in parallel without any problems. Therefore, the entire winding device 10, 12, 14 can be made compact. Further, by storing the winding member 90 in a compact case 110 and guiding the winding member 90 through the introduction hole 100, dustproof and waterproof measures can be realized.

In the explanations so far, the winding devices 10, 12, and 14 have been described as being contained in a case 110 having an introduction hole 100 for introducing the member 90 to be wound. It doesn't have to be. That is, the main parts of the winding devices 10, 12, 14 (the winding devices 10, 12 include the drum 20, the drive source 30, the first guide part 40, the second guide part 50, etc.) are supported by the support device, and the main parts of the winding devices 10, 12, 14 are supported by the support device. A structure may be adopted in which a tube or the like serving as the introduction hole 100 is supported by a support device near the part.

In the explanations so far, the first guide part 40 and the second guide part 50 have been described as including pulleys 42, 44, and 52, but instead of the pulleys, for example, grooves having a smooth surface, etc. It may also include a known structure in which the taking member 90 is fed in different directions.

Note that, as shown in FIG. 5, in the winding device 16, the second guide section 50 is not provided with a pulley or the swing member 60, and the second guide section 50 is an arcuate guide 80. Good too. Note that since the other parts are the same as those of the winding device 10, duplicate explanations will be omitted.

The arc-shaped guide 80 is a rod-shaped member that guides the material to be wound 90 so that the material to be wound 90 changes direction on an arc equidistant from the first guide portion 40 and is wound onto the drum 20. be. The guide 80 replaces the pulley 52 of the second guide portion 50 of the swinging member 60 and facilitates moving the position of the member 90 to be wound around the drum 20 in the width direction of the drum 20. The surface of the guide 80 is made smooth so that the member 90 to be wound up smoothly slides thereon, and the material is selected from materials on which the member 90 to be wound up easily slides. A pulley that slides smoothly along the guide 80 may be used to allow the member 90 to be wound up to slide smoothly. Note that the reason why the direction is changed at a position equidistant from the first guide section 40 is that the winding section wound member 92 wound onto the drum 20 from the second guide section 50 is substantially aligned along the first axis 48. This is to make it parallel to the member 90 to be wound up that is introduced. For example, if the guide is a straight line parallel to the body 22 of the drum 20, as the winding position approaches both ends, the wound member 90 becomes oblique to the guide. Therefore, a force is generated that tries to return to the shortest orthogonal position. Therefore, they are wound near the center, overlapped near the center, and are not wound at both ends, making it impossible to wind them in parallel. On the other hand, like the guide 80, the winding portion 92 is substantially parallel to the winding member 90 introduced along the first axis 48, i.e. On the other hand, if it is at right angles, no force will be generated to shorten the path.

In this way, the winding device 16 has a simple structure and allows the introduction hole 100 to be brought close to the drum 20, while also allowing the winding member 90 to be wound without being affected by the tension of the winding member 90. Can be wound in parallel. Therefore, the entire winding device 16 can be made compact. Further, by storing the winding member 90 in a compact case 110 and guiding the winding member 90 through the introduction hole 100, dustproof and waterproof measures can be realized.
