In order to clarify the directional relationships between the figures, some of the figures show common directions by commonly labeled arrows. Arrows along the direction perpendicular to the plane of the drawing are indicated by dots in circles, as shown in FIG. 4, for example.

FIG. 1 is a perspective view of a wire rope bending device 1 according to one embodiment of the present invention. A wire rope bending device 1 (hereinafter also simply referred to as "device 1") of the present embodiment is used to bend a strand that constitutes a wire rope. Specifically, the device 1 includes a jig 2, and the jig 2 includes a jig main body 10 and a head piece 20. As shown in FIG. Then, as shown in FIGS. 1 and 2, the head piece 20 is moved and pressed against the jig main body 10 with the strand ST arranged between the jig main body 10 and the head piece 20, whereby the jig is 2 can bend the strand ST. In the illustrated example, the jig 1 further includes a rod-shaped member 30, an operating member 40 and a guide rail 50 as moving means for moving the head piece 20. As shown in FIG.

Hereinafter, the moving direction of the head piece 20 with respect to the jig main body 10 is referred to as "first direction D1". Further, the "second direction D2" and the "third direction D3" are directions orthogonal to each other and orthogonal to the first direction D1.

The jig main body 10 has a support portion 11 that supports the strand ST to be bent. In the illustrated example, the jig main body 10 is formed in a U shape as a whole, and both ends of the U shape are arranged along the first direction D1. One end located on one side in the first direction D1 of both ends of the U shape forms the support portion 11 . The support portion 11 is formed with grooves 11a for receiving the strands ST. A threaded hole 12 is formed at the other end of the U-shaped jig main body 10 located on the other side in the first direction D1 to engage with a threaded groove of a rod-shaped member 30 described later. ing. The screw hole 12 extends through the other end of the jig main body 10 in the first direction D1.

The head piece 20 is provided movably in the first direction D1 with respect to the jig main body 10. As shown in FIG. A concave portion 21 is provided on one side of the headpiece 20 in the first direction D1. The concave portion 21 is formed so as to be able to receive the support portion 11 of the jig body portion 10 from one side in the first direction D1 as the head piece 20 moves to one side in the first direction D1. (See Figure 2). By moving the headpiece 20 closer to the support portion 11 and receiving the support portion 11 in the recess 21, the strands ST arranged between the headpiece 20 and the support portion 11 can be bent with the support portion 11 as a fulcrum. .

FIG. 3 is an enlarged view of the headpiece 20 shown in FIG. The headpiece 20 has a base portion 22 facing the support portion 11 of the jig body portion 10 in the first direction D1, and a pair of side portions 23, 23 extending from the base portion 22 to one side in the first direction D1. The pair of side portions 23,23 are spaced apart from each other in the second direction D2, and the support portion 11 can be received between the pair of side portions 23,23. In other words, the concave portion 21 is defined by the pair of side portions 23, 23 and the base portion 22 facing each other in the second direction D2. A groove 21a is formed in the inner surface of the recess 21 to receive the strand ST.

Here, the groove 11a of the support portion 11 and the groove 21a of the recess 21 will be described in more detail.

The groove 11a of the support portion 11 of the jig main body 10 is provided on the surface of the support portion 11 that faces the head piece 20 in a state in which the support portion 11 is received in the recess 21 of the head piece 20 . In the illustrated example, the groove 11a is provided in the surface of the support portion 11 facing the base portion 22 of the headpiece 20 and the surface facing the side portions 23 of the headpiece 20 . A portion of the groove 11a facing the base 22 of the head piece 20 extends along the second direction D2. Portions of the groove 11a facing the side portions 23, 23 of the headpiece 20 extend along the first direction D1. Such a groove 11a stabilizes the bending direction of the strand ST when the strand ST is bent by the supporting portion 11 and the head piece 20. As shown in FIG. That is, the strands ST can be stably bent in the first direction D1.

The groove 21a of the recess 21 of the headpiece 20 is provided in a portion of the surface defining the recess 21 that faces the support 11 in a state in which the support 11 is received in the recess 21 of the headpiece 20 . In the illustrated example, the grooves 21a are provided in the sides 23,23. The groove 21a extends along the first direction D1. Such a groove 21a also stabilizes the bending direction of the strand ST when the strand ST is bent by the supporting portion 11 and the head piece 20. FIG. That is, the strands ST can be stably bent in the first direction D1.

Note that the groove 11a and the groove 21a are provided at positions facing each other. Therefore, when bending the strand ST, the strand ST is received in both the groove 11a and the groove 21a. Thereby, the strands ST can be bent in the first direction D1 more stably.

The dimensions of the recess 21 of the headpiece 20 (specifically, the distance L1 between the side portions 23 and the depth L2 of the recess 21 along the first direction D1) correspond to the diameter of the strand ST to be bent. ing. Note that the headpiece 20 may be replaceable. In this case, a head piece 20 with a large distance L1 and/or depth L2 is used for a strand ST with a large diameter, and a head piece 20 with a small distance L1 and/or depth L2 is used for a strand ST with a small diameter. , can be used selectively.

The rod-shaped member 30 extends in the first direction D1 through the screw hole 12 of the jig main body 10. As shown in FIG. In the illustrated example, the rod-shaped member 30 is a metal shaft. A screw groove is formed on the outer circumference of the rod-shaped member 30, and this screw groove is screwed into the screw hole 12. As shown in FIG. The head piece 20 is connected to one end of the rod-shaped member 30 in the first direction D1. The rod-shaped member 30 is rotatable relative to the headpiece 20 around a rotation axis Ax extending in the first direction D1. When such a rod-shaped member 30 is rotated around the rotation axis Ax with respect to the jig main body 10, the screwing position between the rod-shaped member 30 and the jig main body 10 moves in the first direction D1, and the rod-shaped member 30 moves in the first direction D1 with respect to the jig main body 10. As shown in FIG. Along with this, the head piece 20 moves in the first direction D1 with respect to the jig main body 10 .

The operation member 40 is a member for the operator to apply a rotational force to the rod-shaped member 30 around the rotation axis Ax. The operating member 40 is provided at the other end of the rod-shaped member 30 in the first direction D1. In the illustrated example, the operating member 40 is a metal shaft extending in a direction perpendicular to the first direction D1, but is not limited to this. The operating member 40 may be in the shape of a grip of a screwdriver, or may be in another shape.

The guide rail 50 is a member that guides the movement of the head piece 20 in the first direction D1, and is attached to the jig main body 10. As shown in FIG. In the illustrated example, the guide rail 50 is a plate-like member extending in the first direction D1 and contacts the headpiece 20 from one side in the third direction D3. Such a guide rail 50 suppresses the risk of the headpiece 20 rotating with the rotation of the rod-shaped member 30, so that the posture of the headpiece 20 with respect to the support section 11 can be stabilized.

The guide rail 50 may be fixed to the jig main body 10 by welding, or may be fixed to the jig main body 10 using fastening means such as screws. Further, when the headpiece 20 is replaceable, the mounting position of the guide rail 50 with respect to the jig main body 10 may be changeable according to the dimension of the headpiece 20 in the third direction D3.

In the jig 1 configured in this manner, the operation member 40 is operated to rotate the rod-shaped member 30 around the rotation axis Ax, thereby moving the head piece 20 to one side in the first direction D1, thereby moving the jig main body. It can be pressed against the support part 11 of the part 10 . As a result, the strands ST arranged between the headpiece 20 and the support portion 11 can be bent.

By the way, by using a jig for bending the strand, it is possible to reduce the burden on the worker required for the work of bending the strand. However, depending on the strength and experience of the worker who performs the strand bending work, there is a possibility that the bending state of the strand may vary. In other words, a weak worker may not be able to bend the strand sufficiently. Also, a forceful worker may damage the strands by applying too much force to the strands. In consideration of such points, the device 1 of the present embodiment is devised to suppress variations in the bending state of the strand ST due to the strength and experience of the worker who performs the bending work.

Specifically, the device 1 includes confirmation means 60 for confirming the pressing completion position of the head piece 20 against the jig main body 10 . Then, by moving the head piece 20 to the pressing completion position confirmed by the confirmation means 60, the worker applies an appropriate force to the strand ST by the head piece 20 and the support portion 11 for bending the strand ST. can do. That is, the strand ST can be folded into a desired folded state without being damaged. As a result, it is possible to suppress variations in the bending state of the strands ST due to the force and experience of the worker.

In this embodiment, confirmation means 60 includes sensor 61 and notification means 62 . The sensor 61 detects the pressure applied from the head piece 20 to the support portion 11 of the jig main body 10 in the first direction D1. Reporting means 62 reports the pressure detected by sensor 61 . In the illustrated example, the sensor 61 is arranged between the headpiece 20 and the rod-shaped member 30 . In other words, the rod-shaped member 30 is connected to the headpiece 20 via the sensor 61. As shown in FIG. In addition, in the illustrated example, the notification means 62 has a display section 63 that indicates the pressure detected by the sensor 61 numerically or in waveform. With such a confirmation means 60, by confirming that the pressure displayed on the notification means 62 has reached a predetermined pressure, the head piece 20 is pushed against the support portion 11 of the jig main body 10 to the completed position. You can confirm that you have moved.

Note that the reporting means 62 is not limited to having the display section 63 that displays the pressure. The notification means 62 may be any means that can indicate that the pressure detected by the sensor 61 has reached a predetermined pressure. For example, the notification means 62 may emit a sound or light up when the pressure detected by the sensor 61 reaches a predetermined pressure. Moreover, the sensor 61 and the notification means 62 may be configured integrally. For example, the sensor 61 may have a display section 63 that indicates the pressure detected by the sensor 61. FIG.

Moreover, it is considered that the predetermined pressure varies depending on the diameter of the strand ST. Therefore, when bending the strands ST with various diameters using the jig 1, the predetermined pressure may be appropriately set by the worker.

Further, the device 1 of the present embodiment is devised to facilitate the bending work of the strand ST. Specifically, as shown in FIG. 4, the jig main body 10 is provided with an inclination that guides the strand ST disposed between the head piece 20 and the jig main body 10 toward the groove 11a of the support portion 11. A face 13 is provided. The inclined surface 13 guides the strand ST toward the groove 11a of the support portion 11 as the headpiece 20 moves to one side in the first direction D1 with respect to the jig main body portion 10 . As a result, the strand ST is automatically placed in the groove 11a as the headpiece 20 moves, even if the operator does not place the strand ST in the groove 11a. Therefore, it is not necessary for the worker to hold the strand ST within the groove 11a during the bending operation of the strand ST.

In the illustrated example, the inclined surface 13 extends from the surface 51 of the guide rail 50 facing the other side of the third direction D3 toward the groove 11a. More specifically, the inclined surface 13 is inclined toward the other side of the third direction D3 as it goes toward one side of the first direction D1. According to the jig 1 having such an inclined surface 13, when bending the strand ST, if the strand ST is arranged on the surface 51 of the guide rail 50 between the support portion 11 and the head piece 20, As the headpiece 20 moves to one side in the first direction D1, the strand ST is pushed to one side in the first direction D1 by the headpiece 20, and when the headpiece 20 sufficiently approaches the support 11, It is guided to the other side in the third direction D3 by the inclined surface 13 and finally accommodated in the groove 11a of the support portion 11. As shown in FIG.

Next, the method of using the device 1 of the present embodiment and its action will be described. First, as shown in FIG. 1, the strand ST is arranged between the support portion 11 of the jig main body portion 10 and the head piece 20 . In the illustrated example, the strand ST is placed on the surface 51 of the guide rail 50. FIG. The strand ST is arranged between the support portion 11 and the headpiece 20 so as to extend along the second direction D2.

Next, by operating the operating member 40 to rotate the rod-shaped member 30 around the rotation axis Ax, the rod-shaped member 30 is moved to one side in the first direction D1. As a result, the headpiece 20 moves to one side in the first direction D1. Also, the strand ST is pushed by the headpiece 20 and moves to one side in the first direction D1.

When the headpiece 20 is sufficiently close to the supporting portion 11 of the jig main body 10, the strand ST is pushed by the headpiece 20 and moved to one side in the first direction D1, and is moved toward the inclined surface 13 of the jig main body 10. , and moves to the other side in the third direction D3. As a result, the strand ST is received in the groove 11a formed in the support portion 11. As shown in FIG.

When the head piece 20 further approaches the supporting portion 11 of the jig main body 10, the supporting portion 11 is accommodated in the concave portion 21 of the head piece 20 together with the strand ST, and the strand ST is bent with the supporting portion 11 as a fulcrum. At this time, the strands ST are guided by the grooves 11a and 21a and bent in the first direction D1.

Next, with the support portion 11 and the strands ST housed in the recess 21 of the headpiece 20, the operation member 40 is operated until the confirmation means 60 confirms that the headpiece 20 has moved to the pressing completion position. to press the headpiece 20 toward the support portion 11. As shown in FIG. In the illustrated example, the operation of the operating member 40 is continued until the pressure displayed on the display section 63 of the notification means 62 reaches a predetermined pressure. Then, when the pressure displayed on the display unit 63 reaches a predetermined pressure (that is, when it is confirmed that the headpiece 20 has moved to the pressing completion position), the operation of the operating member 40 is finished. Thereby, the strand ST is bent into a desired bent state.

It should be noted that various modifications can be made to the embodiment described above.

For example, the sensor 61 of the confirmation means 60 may detect the load applied from the head piece 20 to the support portion 11 of the jig main body 10 in the first direction D1. In this case, the reporting means 62 may report the load detected by the sensor 61 . According to such a confirmation means 60, by confirming that the load applied to the support portion 11 of the jig body portion 10 in the first direction D1 has reached a predetermined load, the support portion 11 of the jig body portion 10 can be It can be confirmed that the head piece 20 has moved to the pressing completion position.

If the sensor 61 detects the load, the notification means 62 may indicate that the load detected by the sensor 61 has reached a predetermined load. For example, the notification means 62 may display the load detected by the sensor 61 on the display unit 63, or may emit a sound or light when the load detected by the sensor 61 reaches a predetermined load. can be anything.

In addition, when the sensor 61 detects the load, it is considered that the predetermined load varies depending on the diameter of the strand ST. Therefore, when bending the strands ST with various diameters using the jig 1, the predetermined load may be appropriately set by the worker.

Further, the sensor 61 of the confirmation means 60 may detect the amount of rotation of the rod-shaped member 30 around the rotation axis Ax. In this case, the reporting means 62 may report the amount of rotation detected by the sensor 61 . Specifically, the sensor 61 detects the amount of rotation of the rod-shaped member 30 from the state where the rod-shaped member 30 is at a predetermined position sufficiently away from the support portion 11 in the other side of the first direction D1. good. As described above, the head piece 20 moves in the first direction D1 with respect to the jig main body 10 as the rod-shaped member 30 rotates about the rotation axis Ax. Therefore, by confirming that the rotation amount detected by the sensor 61 has reached a predetermined rotation amount, it is confirmed that the head piece 20 has moved to the pressing completion position with respect to the support portion 11 of the jig body portion 10. can do.

If the sensor 61 detects the amount of rotation, the notification means 62 may indicate that the amount of rotation detected by the sensor 61 has reached a predetermined amount of rotation. For example, the notification means 62 may display the amount of rotation detected by the sensor 61 on the display unit 63, or emit a sound when the amount of rotation detected by the sensor 61 reaches a predetermined amount of rotation. , may be illuminated.

Incidentally, when the sensor 61 detects the amount of rotation, it is considered that the predetermined amount of rotation varies depending on the diameter of the strand ST. Therefore, when bending the strands ST with various diameters using the jig 1, the predetermined amount of rotation may be appropriately set by the operator.

Also, the confirmation means 60 may be a stopper that restricts the movement of the headpiece 20 . In the examples shown in FIGS. 5 to 7, the stopper 60 is fixed to the jig main body 10 and contacts the head piece 20 moved to the pressing completion position from one side in the first direction D1 (see FIG. 6). ).

More specifically, stopper 60 is fixed to guide rail 50 . Stopper 60 includes a base portion 65 and an extension portion 66 extending from base portion 65 . The base 65 is fixed to the surface 52 of the guide rail 50 facing one side in the third direction D3 by fastening means 68 such as screws. The extending portion 66 extends from one end of the base portion 65 in the first direction D1 to one side in the third direction D3. As can be seen from FIG. 7, the extending portion 66 extends from the guide rail 50 to one side and the other side in the second direction D2. The headpiece 20 includes a pair of protrusions 24, 24 protruding from its base 22 to one side in the third direction D3. One and the other of the pair of protruding portions 24, 24 are positioned on one side and the other side of the guide rail 50 in the second direction D2, respectively, and their distal end portions are the extension portions 66 when viewed in the first direction D1. overlapping. Then, when the head piece 20 moves to the pressing completion position, the pair of projecting portions 24, 24 contacts the extending portion 66 of the stopper 60 from the other side in the first direction D1. As a result, movement of the headpiece 20 to one side in the first direction D1 is restricted.

By confirming that the head piece 20 is in contact with the stopper 60, the confirming means 60 confirms that the head piece 20 has moved to the pressing completion position against the support portion 11 of the jig body portion 10. can be confirmed.

When the confirmation means 60 is a stopper shown in FIGS. 5 to 7, the appropriate position (position relative to the support portion 11) at which the movement of the head piece 20 to one side in the first direction D1 is restricted by the stopper 60 is It is considered that it varies depending on the diameter of the strand ST. Therefore, when bending the strands ST with various diameters using the jig 1, the attachment position of the stopper 60 to the jig main body 10 may be appropriately changed by the operator along the first direction D1. In the illustrated example, the base portion 65 of the stopper 60 is formed with an elongated hole 67 extending in the first direction D1. A screw 68 serving as fastening means is inserted through the long hole 67 to fasten the base 65 to the guide rail 50 . Therefore, the mounting position of the stopper 60 with respect to the guide rail 50 (with respect to the jig main body 10) can be changed along the first direction D1.

In the examples shown in FIGS. 5 to 7, the stopper as the confirmation means 60 is fixed to the jig main body 10, but it is not limited to this. As shown in FIGS. 8-9, a stopper as confirmation means 60 may be attached to the headpiece 20 . In this case, when the head piece 20 moves to the pressing completion position, the stopper 60 contacts the support portion 11 of the jig body portion 10 from the other side in the first direction D1 (see FIG. 8).

More specifically, the headpiece 20 includes a pair of projections 24, 24 projecting from its base 22 to one side in the third direction D3. One and the other of the pair of projections 24, 24 are located on one side and the other side of the guide rail 50 in the second direction D2, respectively. Stopper 60 includes a base portion 65 and an extension portion 66 extending from base portion 65 . As understood from FIG. 9, the base portion 65 extends from the guide rail 50 to one side and the other side in the second direction D2. The base 65 is fixed to the ends of the projections 24, 24 of the headpiece 20 by fastening means 68 such as screws. The extending portion 66 extends from one end of the base portion 65 in the first direction D1 to one side in the third direction D3. Then, when the head piece 20 moves to the pressing completion position, the extending portion 66 of the stopper 60 contacts the supporting portion 11 of the jig main body 10 from the other side in the first direction D1. As a result, movement of the headpiece 20 to one side in the first direction D1 is restricted.

By confirming that the stopper 60 is in contact with the support portion 11 of the jig main body 10, the confirming means 60 confirms that the head piece 20 has moved to the pressing completion position against the support portion 11. can be confirmed.

Even if the confirmation means 60 is a stopper shown in FIGS. 8 and 9, the appropriate position (position relative to the support portion 11) at which the movement of the head piece 20 to one side in the first direction D1 is restricted by the stopper 60 is , is considered to vary depending on the diameter of the strand ST. Therefore, when bending strands of various diameters using the jig 1, the attachment position of the stopper 60 with respect to the head piece 20 may be appropriately changed by the operator along the first direction D1. In the illustrated example, the base portion 65 of the stopper 60 is formed with an elongated hole 67 extending in the first direction D1. A screw 68 serving as fastening means is inserted through the long hole 67 to fasten the base 65 to the guide rail 50 . Therefore, the mounting position of the stopper 60 with respect to the headpiece 20 can be changed along the first direction D1.

In addition, in the example described above, the moving means for moving the headpiece 20 includes the rod-shaped member 30, the operating member 40, and the guide rail 50, but is not limited to this. Any means can be employed as means for moving the headpiece 20 in the first direction D1.

Furthermore, in the above example, the wire rope bending device 1 has been described as a device for bending the strands constituting the wire rope, but it is not limited to this. The wire rope bending device 1 may be a device for bending a wire rope. In this case, a wire rope is arranged between the support portion 11 of the jig main body 10 and the head piece 20, and the head piece 20 is moved to one side in the first direction D1 so that the recess 21 of the head piece 20 is fitted with the support portion. By accommodating both 11 and the wire rope, the wire rope can be bent. Also in this case, the wire rope is stably bent in the first direction D1 by receiving the wire rope in the grooves 11a and 21a.

According to the embodiment and modification described above, the wire rope bending device 1 includes the jig 2 and the checking means 60. As shown in FIG. The jig 2 includes a jig main body 10 and a head piece 20. As shown in FIG. The head piece 20 is movable in the first direction D1 with respect to the jig main body 10, and has a concave portion 21 capable of receiving a part (support portion 11) of the jig main body 10 from one side in the first direction D1. have The confirming means 60 is for confirming the pressing completion position of the head piece 20 against the jig main body 10 .

According to such a wire rope bending device 1, the confirming means 60 can confirm that the head piece 20 has moved to the pressing completion position. As a result, it is possible to suppress variations in the bending state of the wire rope and the strands ST constituting the wire rope due to the force and experience of the worker who performs the bending work.

Further, according to the embodiment and modification described above, confirmation means 60 includes sensor 61 and notification means 62 . The sensor 61 detects pressure or load applied from the head piece 20 to the jig main body 10 in the first direction D1.
