DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a front view showing an overall configuration of a wire rope winding device according to an embodiment of the present invention, and FIG. 2 is a plan view thereof.
In the present embodiment, when the present invention is applied to a large overhead crane operated in a steelmaking factory or the like and a wire rope having a diameter of about 40 mm used for the overhead crane is rewinded, an old wire rope wound around the overhead crane is used. It shall be wound up.

  1 and 2, the wire rope take-up device 10 is configured on a base 11 that is horizontally arranged on the floor. In this example, the base 11 has a substantially rectangular shape, and a mounting table 12 around which the wire rope W is collected and wound is disposed. A drive unit 14 that is operated by a motor 13 is disposed at the center of the base 11, and a support shaft 15 is extended in the vertical direction as an output shaft of the drive unit 14. A support base 16 is attached to the support shaft 15, and the support base 16 is rotationally driven around the support shaft 15 while controlling the speed of the motor 13 by controlling the rotational speed of the motor 13. In addition, it has the control panel 17 which controls the action | operation of the motor 13, etc.

  The support base 16 has a substantially box shape, and has a slider 18 supported horizontally so as to be slidable so as to pass through the axis of the support shaft 15 on the support base 16 as shown in FIG. 3 or FIG. The slider 18 is basically a long, generally plate-like body, and is slidably guided by a plurality of guide rollers provided on the support base 16. That is, in this example, eight guide rollers 19 for guiding the vertical direction on both sides of the slider 18 in the width direction and four guide rollers 20 for guiding the width direction of the slider 18 are provided.

  The slider 18 is slid at a predetermined pitch on the support base 16 by a shifter described later, but is positioned and held for each pitch. In this case, as shown in FIG. 6C, a ball plunger 21 and a ball button 22 are provided on the support base 16 and the slider 18, respectively, and are held at the pitch feed position by their cooperative action. In other words, the ball of the ball plunger 21 is elastically engaged with the ball button 22 (recessed portion) by the elasticity of the spring, so that a load exceeding a predetermined value along the sliding direction does not act on the slider 18. The engagement is maintained and the slider 18 is held at a predetermined position on the support base 16.

  As shown in FIG. 1 and FIG. 2, the slider 18 slides so as to extend to guide poles 23 erected on each corner of the base 11, and a pivot arm 24 is supported at the end thereof. The swivel arm 24 protrudes from the end portion of the slider 18 so as to rise obliquely upward, and has a guide portion 25 that guides the wire rope W on one end side. As shown in FIG. 7, the guide portion 25 includes a pair of guide rollers 27 that rotate around a support shaft 26 that can be disposed in the sliding direction of the slider 18, and a support shaft 28 that is disposed in a direction orthogonal to the support shaft 26. And a guide roller 29 that rotates about the wire rope, and guides the wire rope W to be inserted between the guide rollers 27 and 29 from top to bottom. Further, as shown in FIG. 8, the other end side of the turning arm 24 is supported on the slider 18 so as to be rotatable via a pin 30. As shown by a two-dot chain line in FIG. 1, the turning arm 24 rotated so as to fall on the slider 18 is supported by a support 31 provided on the slider 18.

  The turning arm 24 turns around the support shaft 15 via the slider 18. In the apparatus of the present invention, the winding phase of the wire rope W to be wound is adjusted and set in synchronization with the turning operation of the turning arm 24, and the turning arm 24 has a predetermined turning radius corresponding to the winding phase. A shifter 32 is provided for sliding the slider 18 so as to hold it.

  The shifter 32 has a shift adjuster 33 including a cylindrical body 34 that is arranged in the turning radius direction of the turning arm 24 and is driven to rotate about its axis. As will be described later, a guide groove for setting the slide pitch of the slider 18 is formed on the peripheral surface of the cylindrical body 34. The cylindrical body 34 is rotatably supported through bearings 35 on both sides, and slides the slider 18 through a shift guide described later by rotating.

  Here, as a rotational drive mechanism of the shift adjuster 33, a ring gear 36 is disposed around the lower portion of the support base 16 with reference to FIGS. 3 and 5 and the like, and a gear fixed to the input shaft of the speed reducer 37 is attached to the ring gear 36. (Spur gear) 38 meshes. A timing belt 41 is wound around a pulley 39 that is fixed to the output shaft of the speed reducer 37 and a pulley 40 that is fixed to the rotation shaft of the cylindrical body 34. Thus, the rotation shaft of the support base 16 and the shift adjuster 33 is wound around. In other words, the shift adjuster 33 is rotationally driven by the rotation of the support shaft 15 (support base 16). In the present embodiment, the rotational drive mechanism is set to a reduction ratio of 1/2 between the support shaft 15 and the shift adjuster 33, for example. Therefore, when the support shaft 15, that is, the turning arm 24 turns once, the shift adjuster 33 makes a half turn.

  In the above case, a tensioner 42 is attached at an appropriate position of the timing belt 41 so as to mount a pulley 43 and apply an appropriate tension. In the tensioner 42, the pulley 43 has a support arm 44 pivotally supported on the base 11 side via a support shaft 45, and the pulley 43 is urged by a compression coil spring 46 so that the pulley 43 is moved to the timing belt 41. A tension is applied to the.

  FIG. 9 shows a configuration example of the shift adjuster 33 in the present embodiment. Guide grooves 47 for setting the slide pitch of the slider 18 are formed on the peripheral surface of the cylindrical body 34 of the shift adjuster 33. In this case, two guide grooves 47A and 47B intersecting each other are provided. For example, when one guide groove 47A is used for reducing the turning radius of the turning arm 24, the other guide groove 47B is provided on the turning arm 24. Used for expanding the turning radius. It should be noted that any of the guide grooves 47A and 47B can be appropriately used for enlargement or reduction depending on the rotation direction of the shift adjuster 33 or the winding direction of the wire rope W.

  In this example, the reduction ratio ½ of the rotation drive mechanism of the shift adjuster 33 is set so that the slider 18 is fed by one pitch (corresponding to the diameter of the wire rope W) by ½ rotation of the shift adjuster 33. The winding phase of the wire rope W is changed by 10 pitches in the direction of expanding or reducing the turning radius of the turning arm 24.

  Further, the shifter 32 has a shift guide 48 supported so as to reciprocate in the turning radius direction of the turning arm 24 via a follower shoe slidably engaged with the guide groove 47 of the shift adjuster 33. The slider 18 is configured to pitch-feed through the shift guide 48 in accordance with the winding phase.

  10 and 11 show a configuration example of the shift guide 48 in the present embodiment. First, as shown in FIG. 1 or FIG. 4, guide rails 49 and 50 that support and guide the shift guide 48 are laid along the longitudinal direction above the shift adjuster 33. These guide rails 49 and 50 are supported on a base or frame fixed on the base 11 side. Below the base plate 51 of the shift guide 48, a plurality (four in this example) of guide rollers 52 that rotate around the horizontal axis and a plurality (four in this example) that rotate around the vertical axis. A guide roller 53 is attached. The guide roller 52 rolls between the guide rails 49 and 50 so that the vertical direction of the shift guide 48 is regulated. Further, the guide roller 53 rolls on the inner side of the guide rail 49, thereby restricting the width direction of the shift guide 48.

  As shown in FIG. 10, the shift guide 48 erected on the base plate 51 has a pair of opposing guide walls 48 a and 48 b formed so as to have a curved line having a mountain shape, for example. The shift guide 48 reciprocates along the guide rails 49 and 50, and guide walls 48a and 48b are arranged along the moving direction thereof. On the other hand, a roller 55 is rotatably supported around a vertical axis via a bracket 54 at the end of the slider 18 opposite to the turning arm 24. The roller 55 is disposed between the guide walls 48a and 48b at a height position at which the rollers 55 can abut against them.

  As shown in FIG. 10B, the constricted portion 48c between the guide walls 48a and 48b is set so that the roller 55 can pass properly without causing an unnecessary gap. When the roller 55 passes through the constricted portion 48c, a slide pitch of the slider 18 is given. The roller 55 swivels together with the slider 18, but the turning radius is set to be larger than the curvature radius of the angled curve of the guide walls 48a and 48b, and the roller 55 after passing through the constricted portion 48c is guided by the guide walls 48a and 48b. I try not to interfere with it.

  A follow shoe 56 that slidably engages with the guide groove 47 of the shift adjuster 33 is suspended below the base plate 51 of the shift guide 48. As shown in FIG. 11, the follow shoe 56 is attached to the lower end of the rotating shaft 57 that is rotatably supported around the vertical axis, and has a predetermined length along the guide groove 47 of the shift adjuster 33. Yes. A curved relief 56 a is formed so as not to interfere with the groove bottom of the guide groove 47.

  Furthermore, when the shift guide 48 reciprocates along the axial direction of the shift adjuster 33, a winding phase detection unit is provided that detects the winding phase of the wire rope W by detecting the movement position thereof. For example, as shown in FIG. 4, a bracket 58 for detection is attached to an appropriate position (side end portion or the like) of the base plate 51 of the shift guide 48, while a proximity sensor or the like for detecting the bracket 58 for detection is provided on the guide rail 50. The sensors 59 are arranged in a line along the axial direction of the shift adjuster 33.

  In this case, for example, as shown in FIG. 2, when five sensors 59 are arranged at equal pitches between the moving stroke ends of the shift guide 48 and the wire rope W is wound in 10 rows, the winding phase is 2 pitches. Can be detected. The detection signal of the sensor 59 is sent to the control panel 17, and the operating speed of the motor 13 is controlled based on the detection signal.

  Here, in the above case, a wire rope introduction guide 60 as shown in FIGS. 12 and 13 is attached to the wire rope winding device 10 of the present invention. The wire rope introduction guide 60 is erected on the support 16 of the drive unit 14 and rotates integrally therewith. The wire rope W suspended from the overhead crane is introduced into the guide portion 25 of the turning arm 24 via the wire rope introduction guide 60.

  In the specific configuration of the wire rope introduction guide 60, a plurality of pole members 62 are erected from a base member 61 that is directly or indirectly placed on the support base 16. Composed. The top of the tower has a pair of guide rollers 63 that are rotatably arranged opposite to each other (see FIG. 14A), and a wire rope W passes between the guide rollers 63. The guide roller 63 is disposed on the upper extension line of the support shaft 15 of the drive unit 14.

  Further, below the guide roller 63, a guide roller 64 is rotatably disposed at an appropriate position of the pole member 62 on the revolving arm 24 side (see FIG. 14B). The guide roller 64 is disposed offset from the guide roller 63 toward the turning arm 24. Further, a guide roller 65 is rotatably disposed at the distal end portion of the turning arm 24 at a position close to the guide portion 25 (see FIG. 14C). The wire rope W is introduced into the guide portion 25 of the turning arm 24 while being guided by these guide rollers 63, 64 and 65.

In the wire rope winding device having the above-described configuration, when winding the wire rope W of the overhead crane, for example, as shown in FIG. 1, as an example of winding the wire rope W inward from the state in which the turning radius of the turning arm 24 is maximum. explain.
In this case, first, the wire rope W is inserted from the top to the bottom between the guide rollers 27 and 29 of the guide portion 25 of the turning arm 24, and winding onto the mounting table 12 is started. When the motor 13 is operated, the support shaft 15 rotates, and the turning arm 24 turns via the support base 16 and the slider 18, thereby winding the wire rope W that forms the first round (first row). To go. In this case, the wire rope W suspended from the overhead crane is smoothly introduced into the guide portion 25 of the turning arm 24 via the wire rope introduction guide 60.

  The shift adjuster 33 rotates in synchronization with the turning of the turning arm 24. In this example, the follower shoe 56 of the shift guide 48 is engaged with the guide groove 47A1 of the guide groove 47A in the first round as shown in FIG. At the second turn, the shift to the guide groove 47A2 occurs as the shift adjuster 33 rotates. At the end of the first round, the tracking shoe 56 is shifted by one pitch toward the turning radius reduction side, and the shift guide 48 also moves through the tracking shoe 56. The numbers shown in FIG. 9 indicate the shift pitch or the number of turns.

  When the turning arm 24 enters the second turn, the roller 55 disposed at the end of the slider 18 enters the shift guide 48 that is waiting at a position shifted by one pitch. In this case, the roller 55 contacts the guide wall 48a and is urged toward the constricted portion 48c. At this time, a load in the sliding direction acts on the slider 18, whereby the engagement of the ball plunger 21 and the ball button 22 provided on the support 16 and the slider 18 is released, and the roller 55 passes through the constricted portion 48 c. Thus, the slider 18 is slid by one pitch. At this slide position, the ball plunger 21 and the ball button 22 are engaged again, and the slider 18 is held at that position. Therefore, the turning radius of the turning arm 24 is reduced by one pitch, and winding of the second round is performed with this turning radius.

  Thereafter, similarly, the slider 18 is fed by one pitch to the turning radius reduction side until the 10th turn, and the first stage winding is finished. During this time, the operating speed of the motor 13 is controlled based on the detection signal of the sensor 59 that detects the movement position of the shift guide 48. When winding in the turning radius reduction direction, the motor 13 is controlled to increase in speed so as to keep the peripheral speed of the turning arm 24 (the guide portion 25) substantially constant.

  Next, after the winding of the 10th turn is completed, the second turn is started from the winding of the 11th turn. The guide groove 47B is used for the second stage winding. In this case, the follow shoe 56 moves from the guide groove 47A to the guide groove 47B. As shown in FIG. 9B, a convex portion 47a projects from the intersection of the guide groove 47A and the guide groove 47B. When the follower shoe 56 passes over the convex portion 47a, the traveling direction can be changed, so that the follower shoe 56 can smoothly and automatically shift to the second stage winding. Thereafter, the wire rope W can be wound up by the required number of steps by continuing the same operation.

  As described above, according to the wire rope winding device 10 of the present invention, the winding phase of the wire rope W is automatically adjusted in synchronism with the turning motion of the turning arm 24, and so-called phase difference winding is performed without human intervention. Further, step winding is possible, and the wire rope W can be wound up extremely efficiently and safely.

In addition, although the preferred embodiment of this invention was described, this invention is not limited only to embodiment mentioned above, A change etc. are suitably possible as needed.
For example, the winding direction, the number of winding rows or the number of winding stages of the wire rope W can be appropriately increased or decreased as necessary, and the same effects as the above embodiment can be obtained.
