Description

  The present invention relates to a winding / unwinding mechanism for performing the winding of one linear body and the unwinding of the other linear body in synchronization. The present invention also relates to a winding / rewinding mechanism that can rationally increase or decrease the winding amount and the unwinding amount of both linear bodies.

  Many techniques have been developed so far for winding and unwinding the linear body. It is well known that it contributes to industrial development. In particular, winding / unwinding means using a linear body such as a wire is widely used in various technical fields such as power transmission and operation control.

  The technology disclosed in Patent Document 1 below is an apparatus that is equipped with two linear bodies (a linear body for normal winding and a linear body for reverse winding) wound around one rotating drum so as to be freely rewound. It is an example. In the case of this conventional apparatus, the linear body for normal winding and the linear body for reverse winding are wound up or rewound by rotating the rotating drum forward and backward. More specifically, when winding the forward winding linear body, the reverse winding linear body is rewound, and when rewinding the forward winding linear body, the reverse winding linear body is wound. Is.

  The rotating drum in the apparatus of Patent Document 1 has a circular cross section and a constant outer diameter. Two linear bodies (a normal winding linear body and a reverse winding linear body) are wound in close contact with the peripheral surface of the rotating drum having a constant outer diameter. In this apparatus, when the rotating drum rotates once in the forward and reverse directions, the winding amount of the normal winding linear body is Ru1, the rewinding amount of the normal winding linear body is Rd1, and the reverse winding linear body When the winding amount is Ru2 and the rewinding amount of the reverse winding linear body is Rd2, the respective amounts are Ru1 = Rd1 = Ru2 = Rd2. The reason for this is, as is obvious, that the rotating drum has a constant outer diameter. Therefore, in the case of the apparatus disclosed in Patent Document 1, the unwinding amount and unwinding amount of the two linear bodies cannot be changed.

  When these two linear bodies, such as a linear body for normal winding and a linear body for reverse winding, are synchronously wound or unwound, the amount of winding and rewinding at that time are gradually increased. In general, each linear body is wound or unwound by a dedicated winding / rewinding mechanism. Then, with respect to the winding amount and the rewinding amount of each linear body that can be rewound and rewound on the rotary drum of each dedicated device, the rotational speed of the forward winding rotary drum and the reverse winding rotary drum is stepwise. In other words, the rotational speed of each rotating drum is gradually increased or decreased by gradually increasing or decreasing gradually.

  As described above, when the amount of winding and rewinding of the linear body is gradually increased or decreased by gradually changing the rotation speed of the rotating drum, a high degree of rotation controllability with respect to the rotating drum is achieved. Required. However, at present, this cannot be dealt with in terms of skill or technology. As a result, it is difficult to achieve the expected results.

The linear body winding / rewinding mechanism linear body according to the present invention has the following effects <01> to <08>.
<01> A winder that can rotate forward and backward has a gradually increasing and decreasing type winding and unwinding surface on an outer peripheral surface thereof. This gradually increasing and decreasing type winding and rewinding surface automatically and gradually increases or decreases the winding amount of the linear body wound around here and the rewinding amount of the linear body wound back from here. There is a function to. Therefore, by simply rotating the winder forward and backward, and winding and rewinding the linear body by the gradually increasing and decreasing type winding rewinding surface, winding and rewinding of the linear body by the gradually increasing and decreasing method can be performed. Realize.
<02> As a winder having a linear body wound around a gradually increasing and decreasing type winding rewinding surface, a winder having a forward rotation and a reverse rotation is used for winding a linear body by a gradually increasing and decreasing method. Rewinding can be performed in two systems, and more advanced operability (controllability) can be exhibited.
<03> A gradually increasing and decreasing type winding rewinding surface in a winder is formed by machining or the like, and exhibits a stable gradually increasing and decreasing function that does not fluctuate from beginning to end. This stable gradual increase / decrease function that does not fluctuate allows the linear body to be wound and unwound with high accuracy by the gradual increase / decrease method.
<04> A winder having a gradually increasing and decreasing type winding and unwinding surface exhibits a strong take-up force when winding a linear body. For example, when the tip of the linear object is connected to the operation object or the control object, the object can be reliably taken up by an amount corresponding to the winding amount of the linear object. Therefore, a stable and powerful power transmission force can be exhibited as a power machine tool for operation or control.
<05> It can be said that the length of the linear body is virtually unlimited. For example, even with an object installed several tens of meters away from the winder, both of these objects can be connected by the linear body, and the object can be operated and controlled. Therefore, this has not only proximity controllability (proximity operability) but also remote controllability (remote operability).
<06> Main components are a winder and a linear body having a gradually increasing and decreasing type winding and unwinding surface. And a linear body is wound up by a winder so that rewinding is possible. Although this has a special function, the mechanism is extremely simplified. Therefore, it is possible to simplify the configuration.
<07> Since the linear body is simply wound or unwound by a winder, there is almost no fragility from the viewpoint of construction. Therefore, it has long-term durability.
<08> As mentioned above, the main components are very few, such as winders and linear bodies for reverse winding. Therefore, it is possible to rely on this few main components and provide this mechanism as an inexpensive one.

It is the graph which showed the relationship between the two linear bodies and panel angles in the apparatus of FIG.

  A first embodiment of a linear body winding and rewinding mechanism according to the present invention will be described with reference to FIG.

  In the first embodiment of FIG. 1, 11 is a prime mover, 21 is a winder for forward winding, 31 is a winder for reverse winding, 41 and 42 are rotating shafts, 51 is support means, and 61 is a wire for forward winding. The body 71 is a linear body for reverse winding.

  The prime mover 11 illustrated in FIG. 1 is a known or well-known servo motor or pulse motor.

  The forward winding winder 21 and the reverse winding winder 31 in FIG. 1 are made of a material having excellent mechanical properties such as metal, synthetic resin (including FRP), and composite material. Of the parts and members described later, those having no material description are made of materials having excellent mechanical properties such as metals, synthetic resins, and composite materials.

  As is apparent with reference to FIG. 1, the normal winding winder 21 has a gradually increasing and decreasing type winding rewinding surface 22. More specifically, the gradually increasing and decreasing type winding and unwinding surface 22 includes a tapered outer peripheral surface that tapers from one end to the other end. About this taper outer peripheral surface, it can be said that it makes a tapered shape toward the one end part from the other end part. Such a tapered outer peripheral surface has a linear inclination as an example, a convex curve inclination as another example, and a concave curve inclination as another example.

  Regarding the tapered outer surface of the tapered shape (tapered shape) that becomes the gradually increasing and decreasing type winding and rewinding surface 22, this is based on any one of a hemispherical shape, a semi-elliptical spherical shape, a conical shape, a pyramid shape, and the like. In many cases, the shape is a truncated hemispherical shape, a truncated hemispherical spherical shape, a truncated conical shape, or a truncated pyramid shape. To compare with a universal shape, the taper outer surface with a linear inclination is a bowl shape, the taper outer surface with a convex curve inclination is a bell shape, and the taper outer surface with a concave curve inclination is a bowl shape. be able to.

  The reverse winding winder 31 in FIG. 1 also has a gradually increasing and decreasing type winding and unwinding surface 32. In this case, the gradually increasing and decreasing type winding / rewinding surface 32 is also a tapered outer peripheral surface having a tapered shape from one end to the other end, and a tapered outer periphery having a tapered shape from the other end to the one end. Consists of faces. The taper outer peripheral surface of the winding / rewinding surface 32 is the same as the winding / rewinding surface 22 already described in detail.

  In FIG. 1, a series of spiral grooves 23 are formed on the winding and unwinding surface 22 of the gradually increasing and decreasing type in the forward winding winder 21 at a close circumferential pitch, and gradually increasing in the reverse winding winder 31. A series of spiral grooves 33 are also formed on the gradually reducing type winding / rewinding surface 32 at a close circumferential pitch. In this case, each of the spiral grooves 23 and 33 is formed of any one of a semicircular cross section, a semielliptical cross section, and a polygonal cross section (a triangular cross section, a square cross section, a pentagonal cross section, and a polygon having a larger cross section). . Incidentally, both spiral grooves 23 and 33 in the embodiment of FIG. 1 are semicircular in cross section.

  The rotary shafts 41 and 42 in FIG. 1 are made of a material having excellent mechanical properties such as metal, synthetic resin, and composite material, as in the case of the forward winder 21 and the reverse winder 31.

  As for the rotary shafts 41 and 42 and the winders 21 and 31, the case where these members are produced integrally, and the separately produced rotary shafts 41 and 42 and the winders 21 and 31 are integrated. May be combined.

  The forward winder 21, the reverse winder 31, and the rotary shafts 41 and 42 illustrated in FIG. 1 are not a combination of parts, but are an integral part produced as an integral part. . Therefore, one rotating shaft 41 protrudes rightward from the right side surface of the forward winding winder 21, and the other rotating shaft 42 protrudes leftward from the left side surface of the reverse winding winder 31. Further, the gradually increasing and decreasing type winding and unwinding surfaces 22 and 32 of both winders 21 and 31 have the above-described convex curve-like inclination. In addition, the winder for forward winding 21 and the winder for reverse winding 31 have the same shape as each other, and are also bilaterally symmetric with a connecting portion interposed between the two units 21 and 31. Further, the tapered end portion of the forward winding winder 21 faces right, and the tapered end portion of the reverse winding winder 31 faces left. Of course, in the winders 21 and 31 in the example of FIG. 1, the winding amount and the rewinding amount of the linear bodies 61 and 71 described later are equal to each other.

  In FIG. 1, rotating shafts 41 and 42 that are integrated with a forward winding winder 21 and a reverse winding winder 31 are supported via a support means 51 so as to be rotatable forward and backward. For example, the support means 51 in this case is made of a known material such as metal. Furthermore, the support means 51 illustrated in FIG. 1 includes three support portions 53, 54, and 55 that rise from the substrate portion 52. The rotating shafts 41 and 42 are supported by the supporting portions 53 and 54 so as to be able to rotate in the forward and reverse directions with a bearing interposed therebetween.

  In the first embodiment of FIG. 1, the prime mover 11 is attached to and supported by the support portion 55 of the support means 51. More specifically, the prime mover 11 is attached to the support portion 55 so that the output shaft 12 penetrates the support portion 55 from the outside to the inside. In this case, the output shaft 12 and the rotating shaft 41 of the prime mover 11 face each other on the same axis. The output shaft 12 and the rotating shaft 41 are connected by a known coupling 13.

  In the first embodiment of FIG. 1, both the linear body 61 for forward winding and the linear body 71 for reverse winding are each made of a tough long object. As such both linear bodies 61 and 71, those having an arbitrary diameter are employed, from an extremely thin one such as a thread to a thick one such as a rope. In practical terms, the linear bodies 61 and 71 having a small diameter are desirable as long as the strength can be secured. Both linear bodies 61 and 71 are flexible but have little stretchability due to their high tensile strength. Specific examples of the materials of the linear bodies 61 and 71 include metals, synthetic resins, and composites thereof. For these, a plurality of single yarns or wires are twisted together. As an example, the twisted wire is made of twisted aramid fibers.

  In the first embodiment of FIG. 1, the linear body 61 for normal winding is wound on the winding rewinding surface 22 of the winder 21 for normal winding, and the linear body 71 for reverse winding is wound for reverse winding. It is wound around the winding / unwinding surface 32 of the winder 31. Among these, in the case of the linear body 61 for normal winding, the base end part (one end part) is the small diameter part side (FIG. 1) of the winding rewinding surface 22 via the stopper 56 and a screw | thread (no code | symbol). Fixed to the right side). In the case of such a normal winding linear body 61, it is wound around the winding / rewinding surface 22 while being fitted in the spiral groove 23 along with the forward rotation of the forward winding winder 21, and the winding for forward winding is performed. With the reverse rotation of the take-up device 21, the take-up device 21 is unwound from the take-up / rewinding surface 22 while leaving the spiral groove 23. Further, in the case of the reverse winding linear body 71, the base end portion (one end portion) is disposed on the small diameter portion side of the winding / rewinding surface 32 (the left side in FIG. 1) via the stopper 56 and the screw (not shown). ). In the case of the reverse winding linear body 71, the reverse winding winder 31 is unwound from the winding rewinding surface 32 while being detached from the spiral groove 33 along with the normal rotation of the reverse winding winder 31, and the reverse winding winding is performed. With the reverse rotation of the vessel 21, it is wound on the winding / rewinding surface 32 while being fitted in the spiral groove 33. That is, in the case of the embodiment of FIG. 1, the winding direction and the rewinding direction of both linear bodies 61 and 71 are opposite to each other. In this case, the words “forward winding” and “reverse winding” mean that the forward winding wire 21 winds the forward winding wire 61 and the reverse winding winder 31 to reverse winding wire. The case where the linear body 71 is rewound is defined as “forward winding”, and the reverse winding winder 31 winds the reverse winding linear body 71 and at the same time from the forward winding winder 21, the forward winding linear body 61. Is defined as “reverse winding”. This is merely determined for the sake of convenience in explaining the rotation directions of the winders 21 and 31. Accordingly, when one linear body 61 is wound by one winder 21 is referred to as “reverse winding”, and when the other linear body 71 is wound by the other winder 31, “reverse winding” is referred to as “reverse winding”. The technical content is not changed at all.

  The fixing of the linear bodies 61 and 71 to the winders 21 and 31 may be a clamping means such as a clamping type or a clamping type, or an adhesion means (including a welding means in the case of metal). Alternatively, a combination of a plurality of fixing means may be used.

  The linear body winding / rewinding mechanism exemplified in the first embodiment of FIG. 1 is used for operating or controlling an operation object or a control object. It does not matter whether the object is a main part or an accessory part of a machine tool or various devices. More specifically, a swinging movement like a seesaw, a pulling movement that moves linearly, a pulling movement that rotates, and the like. In that case, each front-end | tip part (rewinded other end part) of the linear body 61 for forward winding, or the linear body 71 for reverse winding is connected with the predetermined part of an operation target object or a control target object. More specifically, it is connected to a predetermined portion of the operation object or the control object by the above-described stopper 56 and screw or other known fixing means.

  When the mechanism of the present invention illustrated in the first embodiment of FIG. 1 takes the above-described usage mode, the operating state is as follows.

  When the prime mover 11 is operated in FIG. 1, the rotation of the prime mover 11 is transmitted through the transmission path such as the output shaft 12 → the coupling 13 → the rotation shaft 41 (the rotation shaft 42) for the forward winding device 21 or the reverse winding. It is transmitted to the winder 31. At this time, the winder 21 for the normal winding is in a state where the entire amount of the linear body 61 for the normal winding has been rewound from here, and the winder 31 for the reverse winding has fully wound the linear body 71 for the reverse winding here. Is in a state. That is, in the normal rotation based on the normal winding winder 21, the winder 21 enters the winding state of the normal winding wire 61, and the reverse winding winder 31 rotates in the reverse direction. Thus, the reverse winding linear body 71 enters the rewinding state. Then, the forward rotation of the forward winding winder 21 and the reverse rotation of the reverse winding winder 31 proceed in synchronization (simultaneously), whereby the forward winding linear body 61 becomes the forward winding winder. 21 and the reverse winding linear body 71 is gradually unwound from the reverse winding winder 31. In this case, the forward direction of the forward winder 21 and the reverse direction of the reverse winder 31 have the same rotation direction. This means that the winding rotation of the linear body is referred to as normal rotation, and the rewinding rotation of the linear body is merely referred to as reverse rotation.

  By the way, with regard to the well-known swing type panel, when one end of the panel is pulled, the other end of the panel moves in the direction opposite to the pulling direction, and conversely, when the other end of the panel is pulled One end of the panel moves in the direction opposite to the take-up direction. That is, the swinging panel swings like a seesaw.

When the mechanism of the present invention illustrated in FIG. 1 is applied to the swing panel as described above as an object to be operated or controlled, a forward winding linear body 61 unwound from the forward winding winder 21 is used. The rewinding end portion (tip portion) of the reverse winding linear body 71 is connected to one end portion of the swing type panel and rewinded from the reverse winding winder 31. Is connected to one end of the oscillating panel. Further, the forward winding winder 21 and the reverse winding winder 31 rotate forward and reverse by receiving power transmission from the prime mover 11. In this case, when the forward winding linear body 61 is gradually wound up by the forward winding winder 21, the reverse winding linear body 71 gradually decreases from the reverse winding winder 31 in synchronization therewith. Rewinds. Then, the forward winding linear body 61 taken up by the forward take-up winder 21 takes up one end portion of the swinging panel, and moves in the direction opposite to the take-up direction as the panel end portion is taken up. The movement of the other end of the panel is allowed by the reverse winding linear body 71 rewound from the reverse winding winder 31 gradually. On the contrary, the reverse winding linear body 71 is gradually wound up by the reverse winding winder 31, and at the same time, the forward winding linear body 61 is gradually wound from the forward winding winder 21. When returned, the other end of the swinging panel is taken up by the reverse winding linear body 71, and the forward winding linear body 61 is rewound so that one end of the panel is opposite to the take-up direction. Move in the direction. Thus, the gradual winding of the forward winding linear body 61 and the gradual decreasing rewinding of the reverse winding linear body 71 are performed synchronously, so that the oscillating panel can be oscillated as required without any trouble. The swing control is performed.
To do.

  2nd Embodiment of the linear body winding rewinding mechanism which concerns on this invention is described with reference to FIG.

  In the case of the second embodiment illustrated in FIG. 2, the forward winding unit 21 and the reverse winding unit 31 that are integrated with each other reciprocate along the axial direction of the rotary shaft 11. However, this point is different from that of the first embodiment of FIG. 1, but the other configurations are substantially the same as those of the first embodiment of FIG. As a configuration for reciprocally shifting the forward winding winder 21 and the reverse winding winder 31, for example, a well-known spline fitting method is adopted, and a screw fitting method is used for this. Used together. They are as described below.

  In FIG. 2, the rotating shaft 11 supported so as to be rotatable forward and backward via both support portions 53 and 54 of the support means 51 is a known spline shaft. As is well known, on the outer peripheral surface of the spline shaft, spline grooves and spline teeth along the axial direction are alternately formed in the circumferential direction of the shaft. A spline cylinder 14, a male screw cylinder 15, a female screw cylinder 16, a normal winding winder 21, and a reverse winding winder 31 are multiplexed and concentric on the outer periphery of the rotary shaft 11 formed of the spline shaft. Exist. Among them, a spline shaft (rotary shaft 11) and spline grooves and spline teeth corresponding to the spline shaft (rotary shaft 11) are formed on the inner peripheral surface of the spline cylinder 14 immediately above the rotational shaft 11. The male screw cylinder 15 directly above the spline cylinder 14 has a known male screw (no symbol) formed on the outer peripheral surface thereof. The female screw cylinder 16 immediately above the male screw cylinder 15 is formed with a well-known female screw (not shown) corresponding to the male screw of the male screw cylinder 15 so as to be screw-fit. Further, the winder 21 for reverse winding and the winder 31 for reverse winding, which are sunk to the left and right and integrated with each other, can penetrate the spline cylinder 14, male screw cylinder 15, female screw cylinder 16 and the like. A hole (not indicated) is provided in the axial center portion. These integral winders 21 and 31 are located on the outermost periphery of the multiple parts in a manner covering the female screw cylinder 16 and the like.

  As is apparent with reference to FIG. 2, the spline cylinder 14 fitted with the spline shaft (rotating shaft 11) has one end (right end) at one end (right end) of the winder 21 for normal winding. ) Is fixed to and integrated with this. One end (right end) of the male screw cylinder 15 is also fixed to the inner peripheral surface of one end (right end) of the winder 21 for normal winding, and is interlocked integrally therewith. On the other hand, in the case of the female screw cylinder 16, one end portion (left end portion) is attached to and fixed to the support portion 53. Therefore, in the case of the female screw cylinder 16, it does not interlock with the winder 21 for normal winding. In this case, the screw feed structure using the male screw cylinder 15 and the female screw cylinder 16 may be provided outside the winders 21 and 31 due to the reason that the radial dimension is suppressed and the layout. is there.

  Also in the case of the second embodiment illustrated in FIG. 2, the forward / reverse rotation of the prime mover 11 is transmitted to the rotating shaft 41 and the rotating shaft 42 through the transmission path of the output shaft 12 → the coupling 13 → the rotating shaft 41, thereby The take-up devices 21 and 31 are rotated in forward and reverse directions so that the linear bodies 61 and 71 are gradually wound up and gradually reduced. Therefore, also in the case of the second embodiment, the operation or control of an object such as a swinging panel by winding and unwinding the two linear bodies 61 and 71 is the same as in the first embodiment of FIG. It is the same as explained. At this time, in the second embodiment, both the winders 21 and 31 are shifted along the rotation axis so that the winding and unwinding of both the linear bodies 61 and 71 can be accurately performed as follows. Let it be done.

  In the case of the second embodiment illustrated in FIG. 2, the rotation transmission from the prime mover 11 to the rotating shaft 41 is as described above. In this second embodiment, when the rotating shaft 41 composed of a spline shaft rotates forward or backward, the spline cylinder 14 in a spline fitting state with the rotating shaft 41 rotates in the same direction as the rotating shaft 41. Furthermore, since both the winders 21 and 31 and the male screw cylinder 15 are fixed to the spline cylinder 14, both the winders 21 and 31 and the male screw cylinder 15 rotate together with the spline cylinder 14. Due to such rotation, also in the case of the second embodiment of FIG. 2, both the linear bodies 61 and 71 are wound around the winders 21 and 31 as in the first embodiment, or both winders 21 and 31 are used. Or rewind.

  In the second embodiment of FIG. 2, the linear body for normal winding 61 is wound around the gradually increasing and decreasing type winding rewinding surface 22 of the winder for normal winding 21 and simultaneously the linear body for reverse winding 71 is used for reverse winding. When rewinding from the gradually increasing and decreasing type winding rewinding surface 32 of the winder 31, the rotating shafts (spline shafts) 41 and 42, the spline cylinder 14, the male screw cylinder 15, the winder 21 for normal winding, etc., rotate forward. However, the female screw cylinder 16 fixed to the support portion 53 in a state of being screwed with the male screw cylinder 15 does not rotate. Therefore, in the case of the male screw cylinder 15 rotating in the forward direction, it is fed in the right direction in FIG. Since both winders 21 and 31 interlocked with the male screw cylinder 15 can be shifted in the axial direction by the above-mentioned spline fitting, they move to the right in FIG. On the other hand, the leads of the male and female screw cylinders 15 and 16 are set to be equal to the winding pitch of the spiral grooves 23 and 33, for example. Accordingly, the relationship between the winders 21 and 31 and the linear bodies 61 and 71 in such a case is as follows. First, the gradually increasing and decreasing type winding rewinding surface 22 of the normal winding winder 21 that moves to the right in FIG. 2 while rotating, and the normal winding linear body 61 wound around this will be described with reference to FIG. The linear body 61 for normal winding which exhibits a linear state like this is wound around the gradually increasing and decreasing type winding rewinding surface 22 of the normal winding winder 21 while maintaining the linear state, and further increases gradually. The taper is fitted into the spiral groove 23 while accurately matching the spiral groove 23 of the gradually decreasing type winding / rewinding surface 22. Thereafter, in the positive winding winder 21 that rotates forward while moving in the right direction in FIG. 2 with a lead equivalent to the winding pitch of the spiral groove 23, the positive winding linear body 61 has a gradually increasing and decreasing type winding winding. The guide is accurately guided and guided into the spiral groove 23 of the return surface 22, and sequentially fitted into the spiral groove 23 to be smoothly wound. When wound in this way, the normal winding linear body 61 is unlikely to be twisted or entangled. Next, the gradually increasing and decreasing type winding rewinding surface 32 of the reverse winding winder 31 that rotates and shifts integrally with the forward winding winder 21, and the reverse winding linear shape wound around the winder 31. Regarding the body 71, the reverse winding linear body 71 is smoothly detached from the spiral groove 33 while being gradually unwound from the gradually increasing and decreasing type winding rewinding surface 32 of the reverse winding winder 31, and gradually increased. After the taper is released from the spiral groove 33 of the gradually decreasing type winding / rewinding surface 32, a linear state as shown in FIG. 2 is exhibited. Thereafter, in the reverse winding winder 31 that rotates forward while moving rightward in FIG. 2 with a lead equivalent to the winding pitch of the spiral groove 33, the reverse winding linear body 71 is rewound in the same manner as described above. However, the gradual increase and decrease type winding and unwinding surface 32 is smoothly and linearly separated from the spiral groove 33. In this way, the reverse winding linear body 71 is also unlikely to be twisted or entangled.

  In the second embodiment of FIG. 2, when the winder 21 for reverse winding and the winder 31 for reverse winding are integrally rotated reversely, both winders 21 and 31 in the reverse rotation state have male and female screw cylinders. The feed is applied in the left direction in FIG. In this case, the reverse is true. That is, in the case of the forward winding device 21, the gradually winding linear body 61 is rewound from the gradually increasing and decreasing type winding rewinding surface 22, and in the case of the reverse winding winder 31, the gradually increasing and decreasing type. The reverse winding linear body 61 is wound on the winding / rewinding surface 32.

The eighth embodiment illustrated in FIG. 8 is a modification of the first embodiment.

In this case, the forward / reverse rotation is generally performed within a range of one rotation.

  Next, an example of a panel device in which the mechanism of the present invention is incorporated will be described with reference to FIGS.

  9 and 10, a support body 92 having an inverted U-shaped frame shape is attached to the upper surface of a stationary base 91. On the other hand, the planar panel 93 is supported by being pivotably attached via a support 92. More specifically, swinging fulcrum parts 94 and 94 are provided at the upper and lower central portions on both side surfaces of the panel 93, and the fulcrum parts 94 and 94 are rotatable at both upper ends of the support 92. The panel 93 is provided so as to be swung by supporting it.

  In FIG. 9 and FIG. 10, the mechanism X of the present invention shown in FIG. 1 is mounted as an example at the center of the inner surface of the horizontal portion of the support body 92. Of course, the mechanism X of the present invention in this case may be a mechanism other than that shown in FIG. The linear bodies 61 and 71 rewound from the winders 21 and 31 of the mechanism X of the present invention are respectively known at the swinging end portion of the panel 93 by known means, as clearly shown in FIG. Connection is fixed.

  In the panel device of FIGS. 9 and 10, when the mechanism X of the present invention is rotated forward or backward, that is, the forward winder 21 and the reverse winder 31 are already described. When forward / reverse rotation is performed as described above, the following occurs.

  In the panel operation when the panel 93 in the state of FIG. 10A is changed to the state of FIG. 10B, the panel 93 changes from the state of FIG. 10A to the state of FIG. 10B. Until now, the mechanism X of the present invention (forward winding device 21 and reverse winding device 31) is rotated forward. By doing so, the winder 21 for forward winding rotating in the linear body winding direction winds the forward winding linear body 61 by a predetermined amount and simultaneously rotates in the reverse direction for winding the linear body. The collector 31 rewinds the reverse winding linear body 71 by a predetermined amount. Furthermore, referring to FIG. 10 (A) regarding the forward winding linear body 61 in this case, the forward winding linear body 61 rotates the upper end portion of the panel 93 in a right-tilted state downward with its pulling force. Move. Accordingly, the lower end portion of the panel 93 that is tilted to the right simultaneously rotates upward. With respect to the upward rotation of the lower end portion of the panel, the reverse winding wire that is rewound from the reverse winding winder 31 is used. The shape 71 allows this. Thus, when the forward winding winder 21 and the reverse winding winder 31 are rotated forward by a predetermined amount, the posture of the panel 93 in the state of FIG. 10 (A) is as shown in FIG. 10 (B). To change. After that, when the mechanism X of the present invention (forward winding device 21 / reverse winding device 31) is rotated forward by a predetermined amount, the same linear body winding action or linear body winding as above is performed. Since the returning action occurs, the posture of the panel 93 in the state of FIG. 10B changes as shown in FIG. On the other hand, when the mechanism X of the present invention (forward winding device 21 / reverse winding device 31) is reversely rotated by a predetermined amount when the panel 93 is in the state of FIG. 93 is in the state shown in FIG. 10B, and after that, when the mechanism X of the present invention (forward winding device 21 / reverse winding device 31) is reversely rotated by a predetermined amount, the panel 93 becomes the state of FIG.

  The panel operation described with reference to FIG. 10 is merely a typical example. Of course, the panel 93 is from the state of FIG. 10 (A) to the state of FIG. 10 (C) and / or from the state of FIG. 10 (C) to the state of FIG. 10 (A). During that time, the posture can be changed in small increments.

Next, FIG. 11 and the following equation (4) will be described.
A1 = (B ² + C ² −2BC cos θ) ^1/2 (4)

In the panel device illustrated in FIGS. 9 and 10, the dimensions, distance, length, height, angle, and the like of each part are as indicated by the following symbols.
[A1 = Rewinding length of rewinding linear body 71 (rewinding amount)]
This A1 corresponds to the linear distance from the rotation center line of the reverse winder 31 to the lower end of the panel 93.
[A2 = Rewinding length (rewinding amount) of the linear body 61 for normal winding]
This A2 corresponds to the linear distance from the center line of rotation of the winder 21 for normal winding to the upper end of the panel 93.
[L = height of panel 93]
This L is the vertical dimension of the panel 93 in FIG.
[C = 1 / 2L]
Referring to FIG. 10B, C is a linear distance from the panel fulcrum portion 94 to the left end portion or the right end portion of the panel 93.
[B = height from the rotation center of the mechanism X of the present invention to the panel fulcrum 94]
Referring to FIG. 10 (B), this B is a linear distance from the rotation center of the mechanism X of the present invention (forward winding device 21 / reverse winding device 31) to the fulcrum portion 94, that is, the height. It is.
[Θ = intersection angle between the support 92 and the panel 93]
This θ is the crossing angle between the support 92 and the panel 93 as viewed from the directions of FIGS. 10 (A), (B), and (C). More specifically, in the case of FIG. 10A, the acute angle formed by the support 92 and the lower half of the panel 93 is referred to, and in the case of FIG. 10B, the left of the support 92 and the panel 93 is defined. The right angle formed by the half portion is referred to, and in the case of FIG. 10C, the obtuse angle formed by the support 92 and the upper half portion of the panel 93 is defined.

  The above equation (4) is a well-known equation determined by these “A1”, “A2”, “B”, “C”, “θ”, and the like. FIG. 11 is based on the equation (4), and shows the amount of change between “A1” and “A2” with the change in “θ”. That is, the horizontal axis indicates the change of “θ”, and the vertical axis indicates the change amount of “A1” or “A2”.

  As apparent from FIG. 11, “A1” of the reverse winding linear body 71 and “A2” of the forward winding linear body 61 are symmetric when θ = 90 °. is there. Of these, “A1” decreases in length per rotation angle as “θ” increases. Incidentally, “A1” when “θ” is displaced from 140 ° to 150 ° is about 約 compared to “A1” when “θ” is displaced from 30 ° to 40 °. . In contrast, “A2” increases in length per rotation angle as “θ” increases. Incidentally, “A2” when “θ” is displaced from 140 ° to 150 ° is about three times as large as “A2” when “θ” is displaced from 30 ° to 40 °. This indicates that “A1” and “A2” have the same length while maintaining a symmetrical relationship with θ = 90 ° as the center.

  A typical example of the panel device illustrated in FIGS. 9 and 10 is a solar panel device. As is well known, it is desirable in terms of light collection efficiency that the solar panel (panel 93) should always face the sun from sunrise to sunset. Therefore, the posture angle of the solar panel (panel 93) is changed by the above panel operation so as to follow the change in altitude (elevation angle) of the sun in one day. Of course, the device X of the present invention in this case may be automatically controlled by a program computer with reference to weather data or the like.

  The examples shown in FIGS. 9 and 10 as application examples of the linear body winding and rewinding mechanism according to the present invention are merely examples. With regard to the mechanism of the present invention, in addition to panel swinging operation or swing control, “take-off” such as door door opening / closing operation, handle turning operation, lever push-pull operation, reciprocating motion of a moving body, etc. It can be applied to what is required, or what requires “take-back” and “return” in the opposite direction.

  In the case of the linear body winding and unwinding mechanism according to the present invention, a winder for winding or unwinding the linear body is a special winding / rewinding surface called “gradually increasing and decreasing type winding / rewinding surface”. It has a surface. Then, the tip of the linear body drawn out from the gradually increasing and decreasing type winding rewinding surface of this winder is linked to the operation object, and the rotational power of the winder is transmitted to the operation object. is there. Therefore, it can be applied to an operation control means that requires “take-off” or an operation control means that requires “take-back” and “return” in the opposite direction, etc. It is.
