DETAILED DESCRIPTION

[0027] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 It is a front perspective view schematically showing the structure of a rope threading device 1 according to one embodiment of the present invention. Figure 2 It is a rear perspective view schematically showing the structure of the rope threading device 1 . Figure 3 1 is a top view schematically showing the structure of a rope threading device 1. The rope threading device 1 is a device for threading a plurality of annular components. The annular component is, for example, a sealing device such as an oil seal having an annular reinforcement ring and an annular elastic body portion formed integrally with the reinforcement ring, but may also be an annular component other than a sealing device. In addition, in the rope threading device 1, an x-axis direction and a y-axis direction extending in the horizontal direction and orthogonal to each other, and a z-axis direction extending in the vertical direction and orthogonal to the x-axis direction and the y-axis direction are defined.

[0028] Refer to Figures 1 to 3 The rope threading device 1 includes a support platform 10 that defines a surface 11 extending along the xy plane. In this example, the support platform 10 is, for example, a plate-shaped member, and is arranged at a predetermined height from, for example, the ground where the rope threading device 1 is arranged. The rope threading device 1 includes a handover mechanism 20, a gripping mechanism 30, a pressing mechanism 40, and a holding member 50, which are respectively arranged on the surface 11 of the support platform 10. The handover mechanism 20 has a block 21, for example, a rectangular parallelepiped, fixed to the surface 11. Figure 4 It is along Figure 1 The sectional view of line 4-4. Figure 4 The block 21 has a space 22 defined along the z-axis and a hole 23 defined along the x-axis. In this example, the space 22 passes through from the upper surface to the lower surface of the block 21. On the other hand, the hole 23 passes through a pair of side surfaces of the block 21 that are opposite to each other. The hole 23 intersects with the space 22.

[0029] A pair of rollers 24, 24 are arranged along the z-axis direction in the space 22. In this example, the rotation axis of the rollers 24, 24 is set to be parallel to the y-axis. Each roller 24 has a pad 24a made of an elastic resin material such as a polyurethane resin on its outer peripheral surface. A predetermined gap is formed between the rollers 24, 24. A rope 60 is sandwiched in the gap. The size of the gap is appropriately set according to the diameter of the sandwiched rope 60. The upper roller 24 in the z-axis direction is connected to the rotating shaft 25a of the motor 25. The motor 25 is, for example, a stepping motor. The motor 25 can drive the upper roller 24 to rotate around a rotation axis parallel to the y-axis. On the other hand, the lower roller 24 in the z-axis direction can idle around a rotation axis parallel to the y-axis.

[0030] In this example, the hole 23 is formed into a cylindrical shape, for example. The central axis of the hole 23 is defined to be parallel to the x-axis. The central axis extends from one side of the block 21 through rollers 24, 24 in the block 21 to the other side. The hole 23 defines an opening 23a on one side and an opening 23b on the other side. As described later, the rope 60 passing through the hole 23 from the opening 23a on one side passes between the rollers 24, 24 in the space 22 and passes through the hole 23 again, and is pulled out from the opening 23b on the other side. Specifically, when the rope 60 passes through the gap between the rollers 24, 24, the upper roller 24 is driven by the motor 25 to rotate, and as a result, the rope 60 is pulled in from the opening 23a and sent out from the opening 23b. In this way, the handover mechanism 20 can hand over the rope 60 to the holding mechanism 30.

[0031] return Figures 1 to 3 , the holding mechanism 30 is arranged adjacent to the delivery mechanism 20 in the x-axis direction. The holding mechanism 30 has a holding slider 31. The holding slider 31 can move in the x-axis direction along a linear guide 33 extending parallel to the cylinder body 32 by being driven by a cylinder body 32 extending in the x-axis direction. The cylinder body 32 is, for example, an air cylinder, which can make the holding slider 31 slide in the x-axis direction along the linear guide 33 by compressed air. The linear guide 33 has a track 33a extending in the x-axis direction and a block (not shown) that can slide along the track 33a. The block is connected to the holding slider 31. In this example, the track 33a extends from the motor 25 of the delivery mechanism 20 in the x-axis direction.

[0032] The gripping slider 31 includes a first slider 34 connected to the linear guide 33, a cylinder 35 fixed to the first slider 34 and extending in the z-axis direction, a second slider 36 connected to the cylinder 35, and a chuck mechanism 37 fixed to the second slider 36. The first slider 34 can slide in the x-axis direction along the linear guide 33 by driving the cylinder 32. The second slider 36 can slide in the z-axis direction by driving the cylinder 35. In addition, the chuck mechanism 37 includes a guide member 37a and a pair of gripping blocks 37b, 37b that can slide in the z-axis direction by the guidance of the guide member 37a. In the chuck mechanism 37, for example, the pair of gripping blocks 37b, 37b can be moved closer to or farther from each other in the z-axis direction by compressed air.

[0033] like Figure 3 As shown in FIG. 1 , the chuck mechanism 37 can move along the moving path P1 shown by the dotted line as the holding mechanism 30 slides in the x-axis direction. Figure 3 In the top view, the moving path P1 is defined on the extension line of the hole 23 of the block 21 of the delivery mechanism 20. In this example, the starting point S of the moving path P1 is defined to be adjacent to the block 21 of the delivery mechanism 20 in the x-axis direction. As described later, at the starting point S of the moving path P1, the chuck mechanism 37 can use a pair of holding blocks 37b, 37b to hold the rope 60 sent out from the opening 23b of the block 21 in the z-axis direction. The holding slider 31 can slide to the end point E of the moving path P1 under the guidance of the linear guide 33 while the rope 60 is held by the holding blocks 37b, 37b. In this way, the rope 60 can be arranged on the moving path P1. In addition, a retaining component 50 is arranged on the moving path P1.

[0034] return Figures 1 to 3 The pressing mechanism 40 has a pressing slider 41. The pressing slider 41 can slide along the y-axis direction by driving a cylinder 42 extending along the y-axis direction. The pressing slider 41 has a third slider 43 connected to the cylinder 42, a cylinder 44 fixed to the third slider 43 and extending along the z-axis direction, a fourth slider 45 connected to the cylinder 44, and an arm member 46 fixed to the fourth slider 45. The third slider 43 can slide along the y-axis direction by driving the cylinder 42. The fourth slider 45 can slide along the z-axis direction by driving the cylinder 44. In addition, the arm member 46 has a pair of arms 46a, 46a extending parallel to each other in the y-axis direction and V rollers 46b respectively held on the lower surface of each arm 46a. The V roller 46b is supported on the arm 46a in a manner that can rotate around a rotation axis parallel to the y-axis. The V roller 46b has a v-groove formed around the rotation axis.

[0035] like Figure 3 As shown in FIG. 1 , the arm member 46 can move along the moving path P2 shown by the dotted line as the pressing slider 41 slides. Figure 3 In the top view, the moving path P2 intersects the moving path P1. In this example, the moving path P2 is orthogonal to the moving path P1. In this way, the arm member 46, that is, the pair of arms 46a, 46a, can enter the moving path P1. As a result, as described later, the V-rollers 46b, 46b of the arms 46a, 46a can press the rope 60 arranged on the moving path P1 from the upper side to the surface 11 in the z-axis direction using the v-grooves of each V-roller 46b. In addition, when the arm member 46 enters the moving path P1, the retaining member 50 is arranged between the pair of arms 46a, 46a in a top view. Therefore, the v-grooves of the V-rollers 46b can press the rope 60 on both sides of the retaining member 50 in the x-axis direction.

[0036] Refer to Figures 1 to 4 , the retaining component 50 is arranged in a hole 12 formed in the support platform 10. The hole 12 passes through from the surface 11 of the support platform 10 to the back surface 13. The retaining component 50 is, for example, a cylindrical component having a central axis parallel to the z-axis. The front end, i.e., the upper end, of the retaining component 50 is formed into a roughly hemispherical shape. The diameter of the retaining component 50 orthogonal to the central axis is set according to the inner diameter of the annular component. A retaining groove 51 extending in the x-axis direction is formed at the upper end of the retaining component 50. The retaining groove 51 is recessed from the upper end to the lower end of the retaining component 50. As shown Figure 4 As shown, the bottom surface 51a of the retaining groove 51 is defined to be parallel to the x-axis. That is, when viewed from above, the groove 52 is orthogonal to the retaining groove 51. A groove 52 extending along the y-axis direction is also formed at the upper end of the retaining member 50. The groove 52 is recessed from the upper end to the lower end of the retaining member 50. The depth of the groove 52 is greater than the depth of the retaining groove 51.

[0037] like Figure 4 As shown, the retaining member 50 can be displaced along the moving path P3 indicated by the dotted line. In this example, the moving path P3 is defined to be parallel to the z-axis. In addition, the moving path P3 is orthogonal to the moving path P1. The retaining member 50 is configured with its upper end at a predetermined height H1 from the surface 11 of the support platform 10 in the initial position. That is, the retaining member 50 protrudes from the surface 11 at a predetermined height H1. When the retaining member 50 is displaced from the initial position to the final position, the retaining member 50 protrudes from the surface 11 at a height higher than the height H1. As described later, if the retaining member 50 protrudes from the surface 11 at a height higher than the height H1, a state is established in which an annular member can be mounted to the retaining member 50 from the upper end of the retaining member 50.

[0038] Next, the usage of the rope threading device 1 is described below. Figure 5As shown, in the holding mechanism 30, the holding blocks 37b, 37b of the holding slider 31 are arranged at the starting point S of the moving path P1. At the starting point S, the holding blocks 37b, 37b are arranged at a height relative to the opening 23b of the block 21. At this time, the holding blocks 37b, 37b move away from each other in the z-axis direction, and a predetermined gap is ensured between the holding blocks 37b, 37b. The rope 60 is inserted between the rollers 24, 24 from the opening 23a of the block 21 of the handover mechanism 20 in advance. The upper roller 24 is rotated by the drive of the motor 25, whereby the rope 60 between the rollers 24, 24 is pulled in from the opening 23a and transported toward the opening 23b. In this way, the front end of the rope 60 is pulled out from the opening 23b. As a result, the rope 60 is arranged between the holding blocks 37b, 37b. The rotation of the upper roller 24 stops.

[0039] In the holding mechanism 30, the holding blocks 37b, 37b move toward each other in the z-axis direction and hold the rope 60 therebetween. Figure 5 As shown, the holding member 50 protrudes from the surface 11 at a predetermined height H1. On the other hand, in the pressing mechanism 40, the arm member 46 retreats outward from the moving path P1. The second slider 36 rises from the surface 11 based on the sliding in the z-axis direction so that the holding blocks 37b, 37b do not contact the holding member 50 when sliding in the x-axis direction. In this state, the holding slider 31 slides in the x-axis direction along the linear guide 33 toward the end point E of the moving path P1. Figure 6 As shown, at the end point E, the second slider 36 slides in the z-axis direction and descends toward the surface 11. As a result, the rope 60 is disposed in the holding groove 51 of the holding member 50 disposed on the moving path P1. The front end of the rope 60 is held by being sandwiched between the holding blocks 37b, 37b, and on the other hand, the rope 60 is held by being sandwiched between the rollers 24, 24, so that a predetermined tension is established on the rope 60.

[0040] Afterwards, in the pressing mechanism 40, the fourth slider 45 rises from the surface 11 based on the slip in the z-axis direction. The pair of arms 46a, 46a of the arm member 46 rises to a height greater than the height of the rope 60 from the surface 11. Based on the slip of the third slider 43 in the y-axis direction, the arm member 46 moves along the moving path P2. In this way, the pair of arms 46a, 46a enters the moving path P1. Specifically, the V-grooves of the V-rollers 46b, 46b of the arms 46a, 46a are arranged above the rope 60. At this time, the fourth slider 45 approaches the surface 11 based on the slip in the z-axis direction. As a result, as shown in FIG. Figure 7 As shown, the V grooves of the V rollers 46b, 46b of the arms 46a, 46a press the rope 60 toward the surface 11. In the holding member 50, the rope 60 is pressed toward the bottom surface 51a of the holding groove 51. In this way, the first stage is established.

[0041] Then, if Figure 8 As shown, the holding member 50 moves, i.e., shifts, along the moving path P3. Specifically, the holding member 50 increases the height from the surface 11 while holding the rope 60 in the holding groove 51. While the tension of the rope 60 is maintained in this way, the rope 60 extends along the outer peripheral surface of the holding member 50 between the V rollers 46b, 46b to the holding groove 51, and then extends from the holding groove 51 along the outer peripheral surface of the holding member 50. In this way, the second stage is established. At this time, the annular member 70 is mounted on the holding member 50 from the upper end of the holding member 50. In this example, the annular member 70 is placed on a pair of arms 46a, 46a. The annular member 70 is mounted on the holding member 50, for example, in a state where the orientation in the z-axis direction, i.e., the up-down direction, is consistent. At this time, the number of annular members 70 installed is measured. The rope 60 is arranged between the outer peripheral surface of the holding member 50 and the inner peripheral surface of the annular member 70. In this way, the rope 60 passes through a plurality of annular members 70.

[0042] When a predetermined number of annular components 70 are mounted on the retaining component 50, the rope 60 is cut, for example, in the groove 52 at the upper end of the retaining component 50. The depth of the groove 52 is greater than the depth of the retaining groove 51, so the tip of a cutting unit such as scissors can be easily inserted into the groove 52 to cut the rope 60. The front end of the rope 60 held between the holding blocks 37b, 37b is knotted with the base end of the rope 60 cut in the groove 52. In this way, a plurality of annular components 70 are bundled. Thereafter, for example, the upper roller 24 is reversed by the motor 25 to pull the rope 60 back into the block 21. For example, the front end of the rope 60 is pulled back to a length clamped by the holding blocks 37b, 37b at the starting point S. In this way, the action of the rope threading device 1 is completed. Thereafter, the plurality of annular components 70 bundled by the rope 60 are packaged.

[0043] In the rope threading device 1 as described above, when the holding slider 31 is moved from the starting point S to the end point E along the moving path P1 in a state where the rope 60 is held by the holding blocks 37b, 37b, the rope 60 is arranged in the holding groove 51 at the upper end of the holding member 50. Then, after the pressing slider 41 is moved along the moving path P2, the rope 60 is pressed toward the surface 11 by the V groove of the V roller 46b of the arm 46a. In this state, when the holding member 50 is displaced along the moving path P3, the rope 60 is arranged in the holding groove 51 and the outer peripheral surface of the holding member 50 on the surface 11 of the support table 10. In this way, the annular member 70 can be installed from the upper end of the holding member 50. At this time, when the annular member 70 is installed from the upper end of the holding member 50, the rope 60 passes through a plurality of annular members 70. In this way, a plurality of annular members 70 can be easily bundled.
