Furthermore, the portion of the introduction guide 16 through which the linear member 99 is inserted does not have to be a hard tube structure, and for example, the guide hole 16D may be formed so as to penetrate the support rod 16B up and down. In addition, the introduction guide 16 may be fixed to the container holding part 11A, and may rotate integrally with the container 80A. Specifically, a beam member fixed across the upper surface of the container 80A in an open state may be provided, and the guide hole 16D may be formed in the beam member.

The floor of the factory is fixedly supporting the base 13 . Then, the winding device 10A accommodates the linear member 99 fed from the wire manufacturing machine 91 in the container 80A through the guide hole 16D of the introduction guide 16 . Moreover, the front-end|tip of the linear member 99 is hold|maintained by the container internal holder 81 provided in the lower end part of the inner surface of the container 80A.

As shown in FIG. 3 , the container inner holder 81 has a structure in which a support pipe 81B is rotatably supported by a base portion 81A fixed to the container 80A. Furthermore, the base portion 81A is fixed to the container 80A so that the axial direction of the support pipe 81B is directed toward the inner surface of the container 80A in the circumferential direction. In addition, the front-end|tip part of the linear member 99 passes through the support pipe 81B, and is fixed to the support pipe 81B by a belt etc. so that it may rotate integrally.

In addition, although the container 80A has the container inner holder 81, it does not need to have the container inner holder 81.

As shown in FIG. 1 , the controller 17 of the winding device 10A is equipped with a console 17C, and the console 17C can be used to switch between the manual mode in which the rotation speed of the container holding part 11A can be set arbitrarily, and the rotation speed according to the linear member 99. The rotation speed is an automatic mode in which the rotation speed of the container holder 11A is automatically set. In addition, in order to operate the winding device 10A in the automatic mode, the information on the feeding amount of the linear member 99 is taken in from the wire manufacturing machine 91 to the controller 17 . And, if the winding device 10A operates in the automatic mode, the microcomputer 17A included in the controller 17 calculates the rotational speed of the linear member 99 according to the feed amount of the linear member 99 per unit time based on the above information, and The servo motor 14 is controlled so that the container holder 11A rotates at the same rotational speed as the linear member 99 fed from the wire manufacturing machine 91 . In addition, when the winding device 10A operates in automatic mode, the microcomputer 17A corresponds to the "first rotation control unit" in the scope of the patent application.

Moreover, when the wire rod manufacturing machine 91 does not output the information of the feeding amount of the wire-shaped member 99, as long as the output part of the wire rod manufacturing machine 91 is provided with a detection device for detecting the feeding amount of the wire-shaped member 99, and the detected The detection result of the device may be taken into the controller 17 as information on the feed amount of the linear member 99 from the feed source of the linear member 99 .

The above is the description of the configuration of the winding device 10A according to the present embodiment. Next, the effect of the winding device 10A will be described. As a preparation before the start-up of the manufacturing equipment 90A, a certain amount of linear members 99 are hung from the wire manufacturing machine 91 and passed through the guide holes 16D of the introduction guide 16, and the container inner holder 81 in the container 80A holds the linear members. 99 front end. Then, a portion of the linear member 99 above the introduction guide 16 is made to extend straight. In addition, 10 A of winding apparatuses are set to automatic mode beforehand. Then, the start switch of manufacturing equipment 90A is turned on. Then, the wire manufacturing machine 91 starts simultaneously with the winding device 10A, and the wire member 99 is fed downward while rotating from the wire manufacturing machine 91, and the winding device 10A rotates the container at the same rotation speed as the wire member 99. The holder 11A is rotated so that the linear member 99 and the container 80A are not rotated relative to each other, and the linear member 99 is accommodated in the container 80A. In addition, in the container 80A, the holder 81 in the container supports the front end portion of the linear member 99 in a rotatable shape. Therefore, in the initial state immediately after the start-up of the manufacturing equipment 90A, even if the linear member 99 is twisted, because it is held by the container. The front end portion supported by the holder 81 is rotated so that the torsion is also released.

In addition, the linear member 99 fed in a linearly extended state is pressed against the bottom surface of the container 80A or the linear member 99 stacked on the bottom surface to be elastically deformed by bending, and thus pushed by the subsequent linear member 99. The container 80A is pressed against the inner surface of the container 80A or the linear member 99 overlapping the bottom. Thus, the linear member 99 is wound in a ring shape along the inner surface of the container 80A. In this way, the winding device 10A of the present invention makes the linear member 99 bend and wind along the inner surface of the container 80A by utilizing the elastic recovery after the bending elastic deformation of the linear member 99, so that it can achieve Winding of the linear member 99 suppressing the load on the linear member 99 can manufacture the wound body 98 of stable quality. In addition, since the container 80A is rotated at the same rotational speed as the linear member 99 by the rotation drive device 15, twisting of the wound linear member 99 is suppressed, thereby improving the quality of the wound body 98. Stablize. Then, after the linear member 99 having a desired length is wound in the container 80A, the manufacturing equipment 90A is stopped, and the container 80A can be removed from the container holding portion 11A. Then, the winding body 98 of the linear member 99 can be shipped in a state accommodated in the container 80A.

Furthermore, the winding device 10A may be set in a manual mode instead of an automatic mode, and the rotation speed of the container holder 11A may be adjusted so that twisting of the linear member 99 does not occur visually. In addition, when the wire rod manufacturing machine 91 is a wire rod manufacturing machine that feeds the linear member 99 without rotating, the rotation of the container holder 11A of the winding device 10A may be stopped and the wire rod fed from the wire rod manufacturing machine 91 may be stopped. The linear member 99 is housed in the container 80A and wound up. Furthermore, the wound body 98 may be shipped in a state taken out from the container 80A. For this reason, for example, it is also possible to preliminarily set the container inner holder 81 to be fixed to the container 80A by bolts or the like penetrating the container 80A inside and outside, and use the operation performed from the outside of the container 80A after the winding body 98 is completed. Holder 81 is removed from container 80A, and wound body 98 is taken out from container 80A and shipped. In addition, instead of the above-mentioned container 80A, the container-shaped container holding part 11A of this embodiment fitted outside the container may be used as a "container", and the rotation support shaft part 12 may be used as a "container rotation holding part". .

[Second Embodiment] A manufacturing facility 90B of this embodiment is shown in FIGS. 4 to 6 . As shown in FIG. 4, the winding device 10B of the manufacturing facility 90B of the present embodiment has a configuration in which a twist detection device 40 is added to the winding device 10A of the above-mentioned first embodiment.

As shown in FIG. 5 , the twist detection device 40 includes a pair of facing members 42 , a pair of passage guides 43 sandwiched and fixed therebetween, and a pair of side abutting portions 41 . The pair of opposing members 42 is, for example, a transparent acrylic plate or a tempered glass plate, is formed in a strip shape extending in the vertical direction, and faces each other in the horizontal direction. In addition, a flat space is formed between the pair of opposing members 42 by sandwiching the side abutting portion 41 and the passing guide 43 . In this flat space, for example, the size in the opposing direction of a pair of opposing members 42 is about 1 to 3 times the diameter of the linear member 99, and the size in the direction perpendicular thereto is 8 to 30 times the diameter of the linear member 99. about.

The pair of passing guides 43 is disposed at the center in the width direction of both ends in the longitudinal direction of the pair of facing members 42 . In each passage guide 43 , a passage hole 43A of a size just enough to pass the linear member 99 penetrates vertically, and a pair of passage holes 43A of a pair of passage guides 43 are arranged coaxially. In addition, the passing hole 43A is formed close to the one facing member 42 side of the pair of facing members 42 , and the linear member 99 passing through the pair of passing holes 43A comes into contact with the inner surface of the one facing member 42 . .

The pair of side abutting portions 41 has a strip shape, and a plurality of through-holes 41A penetrating in the thickness direction are arranged in a row in the longitudinal direction on each of the side abutting portions 41 . Correspondingly, in the pair of opposing members 42 , a plurality of through-holes 42A are arranged in a plurality of rows in the longitudinal direction on both sides of the left and right sides with respect to the center in the width direction. And, the through-holes 42A of any row of the left and right of a pair of opposing members 42 overlap with the through-holes 41A of each side contact portion 41, and each side contact portion 41 is connected by a plurality of bolts and nuts passing through these holes. It is fixed between a pair of opposing members 42 .

As shown in FIG. 4 , a pair of sensors 44 are laid on opposing surfaces of the pair of side abutting portions 41 . Each sensor 44 is a so-called pressure sensor whose resistance changes when an external force is applied. In addition, the controller 17 includes a pair of detection circuits connected to the pair of sensors 44 , and when the linear member 99 comes into contact with each sensor 44 , the detection signal of each detection circuit is taken into the microcomputer 17A.

Furthermore, the sensor 44 may be an optical sensor. In this case, for example, as long as the optical axis extends along the opposing surfaces of the pair of side contact parts 41, it is between the sides of each side contact part 41. The light emitting part and the light receiving part of the photosensor are installed at both ends of the longitudinal direction, and the linear member 99 is close to each side contact part 41 to block the light between the light projecting part and the light receiving part to detect the linear member. 99 is close, so that's it. In addition, when the linear member 99 is a conductive member, as long as it is, the pair of sensors 44 and the passing guide 43 on one side are made of conductive metal, and the controller 17 has a control whether the linear member 99 The detection circuit that conducts detection through the conduction connection between the guide 43 and each sensor 44 is sufficient.

As shown in FIG. 4 , the twist detection device 40 is arranged between the feed nozzle 91A and the holding pipe 16C so that a pair of passing holes 43A are aligned on the same axis, and is fixed to the stand 92 . And, the linear member 99 fed from the feeding nozzle 91A passes through the holding pipe after passing through the pair of passing holes 43A in a state of being close to one of the pair of facing members 42 and abutting against the inner surface. 16C and accommodated in container 80A.

The winding device 10B of the present embodiment adjusts the rotation speed of the container holder 11A based on the detection result of the twist detection device 40 . For this reason, when the power supply of the winding device 10B is turned on, the microcomputer 17A of the controller 17 executes a setting program not shown in the figure, and for any detection result of the pair of sensors 44, it is required to increase the capacity of the container holder 11A. Rotation speed or decrease the setting of the rotation speed of the container holder 11A. On the other hand, when the rotation of the container holder 11A is relatively slow compared to the rotation of the linear member 99, the linear member 99 is twisted in one direction under the same load state in advance experimentally. The sensor 44 abutted by 99 is defined as the first sensor 44 , and the sensor 44 different therefrom is defined as the second sensor 44 . Furthermore, when the linear member 99 is twisted in another direction in the opposite load state to the above, it is better to confirm in advance that the linear member 99 is in contact with the second sensor 44 .

In addition, in response to the request set above, it is set to increase the rotational speed of the container holding portion 11A when the first sensor 44 detects the contact of the linear member 99 . Also by this setting, when the second sensor 44 detects the contact of the linear member 99, the rotation speed of the container holding part 11A is set to be reduced. In addition, since it is determined whether or not to change the increase and decrease of the rotational speed of the container holder 11A when performing these settings, the increase and decrease can be set arbitrarily as necessary.

When the wire manufacturing machine 91 and the winding device 10B are activated by the starting operation of the manufacturing equipment 90B, as described in the first embodiment, the winding device 10B uses the wire-shaped member 99 obtained from the wire manufacturing machine 91 The feed amount is calculated as the rotational speed of the container holding part 11A, and the container holding part 11A is driven to rotate so as to attain the rotational speed. However, the rotational speed of the linear member 99 and the rotational speed of the container holding portion 11A do not coincide as theoretically, and the linear member may be caused by the difference between the rotational speed of the linear member 99 and the rotational speed of the container holding portion 11A. 99 twists. In this regard, the microcomputer 17A of the controller 17 repeatedly executes the speed control program PG1 shown in FIG. 6 at a predetermined cycle (for example, 10 to 100 [msec]), and increases or decreases the container holder 11A so as to reduce the twist of the linear member 99. rotation speed.

Specifically, when the speed control program PG1 is executed, it is detected whether the first sensor and the second sensor 44 both detect the contact of the linear member 99 (S10, S11). If none of the controllers 44 detects the contact of the linear member 99 (NO in both S10 and S11), the speed control program PG1 is exited without changing the current rotation speed. On the other hand, when the first sensor 44 detects the contact of the linear member 99, after performing the speed-up process (S12) of speeding up the rotational speed of the container holder 11A by the above-mentioned increment set in advance (S12), then Exit the speed control program PG1. On the other hand, when the second sensor 44 detects the contact of the linear member 99, the speed control is exited after the deceleration process (S13) is performed to decelerate the rotational speed of the container holder 11A by the previously set amount of reduction. Program PG1.

Furthermore, the microcomputer 17A when executing the speed control program PG1 corresponds to the "second rotation control unit" in the scope of the patent application.

Thus, according to the winding device 10B of the present embodiment, the twisting of the linear member 99 is detected by the twist detection device 40 by utilizing the nonlinear shape when the linear member 99 is twisted, and the container is controlled based on the detection result of the twist detection device 40 . The rotation speed of the holding portion 11A is to reduce the twist, so it can reduce the twist caused by various factors. This configuration also enables the winding device 10B to control the rotation speed of the container holder 11A based only on the detection result of the twist detection device 40 without obtaining information on the feeding amount of the linear member 99 from the wire manufacturing machine 91 . However, if the information on the feeding amount of the linear member 99 from the wire manufacturing machine 91 is also used as in the present embodiment, the twist of the linear member 99 can be removed early.

In addition, the twist detection device 40 sandwiches the linear member 99 between the pair of opposing members 42 , so the meandering behavior of the linear member 99 due to twist is stable, and the detection result of the twist of the linear member 99 is stable. In addition, since the pair of facing members 42 are transparent, twisting of the linear member 99 can be confirmed visually.

Furthermore, in the present embodiment, although both of the pair of side contact parts 41 have the sensor 44, it is also possible that only one side contact part 41 of the twist detection device 40 has the sensor. 44. Wind the wire-shaped member 99 while maintaining the state that the wire-shaped member 99 is slightly twisted to one side, and the sensor 44 detects this situation only when the amount of twist on one side becomes large. More specifically, the winding device 10B rotates the container holder 11A in advance at a rotation speed slightly slower than the rotation speed calculated from the information on the feed amount of the linear member 99 from the wire manufacturing machine 91, so that the linear member 99 is gradually twisted to one side, and when contact of the linear member 99 is detected by one sensor 44, the rotation speed of the container holder 11A is increased for a certain period of time to eliminate the twist. Conversely, the rotation speed of the container holder 11A may be slightly faster than the rotation speed of the linear member 99, and when the contact of the linear member 99 is detected by the other sensor 44, a certain period of time may be activated. The rotation speed of the container holder 11A is internally reduced to eliminate twisting. In addition, as the twist detection device, for example, a ring or a cylinder surrounding the linear member 99 may be provided between a pair of passing guides 43, and the wire may be detected by whether or not the linear member 99 abuts against the ring or cylinder. The twisting structure of the linear member 99 can also be made by using an imaging device that photographs a pair of linear members 99 that pass between the guide parts 43 and an image analysis that analyzes the image captured by the imaging device. The part detects the twisting of the linear member 99. Moreover, only one of a pair of facing member 42 may be transparent. In addition, the pair of opposing members 42 may be both non-transparent.

[Third Embodiment] FIG. 7 shows a winding device 10C according to this embodiment. The winding device 10C is provided with a tilting support for tilting the twist detection device 40 at a point where the rotation axis of the container holder 11A is inclined relative to the vertical direction. The point of the part 49 differs from the winding apparatus 10A, 10B of 1st and 2nd embodiment.

Specifically, the support base 13V of the rotation driving device 15C of the winding device 10C rotatably supports the rotation support shaft portion 12 such that the rotation axis of the container holding portion 11A is at an inclination angle of, for example, 30 to 45° with respect to the horizontal direction. , the opening of the container 80A faces obliquely upward.

The tilt support portion 49 has a bracket 49B standing up from the base portion 49A. In addition, the upper end portion of the bracket 49B is hingedly connected to the middle portion in the longitudinal direction of the twist detection device 40, and the twist detection device 40 is tilted around a tilt axis parallel to the opposing direction of the pair of side abutting parts 41, and can be arbitrarily tilted. The tilting posture of is fixed. Furthermore, the bracket 49B is fitted and has a plurality of tubes and has a telescopic structure, so that the vertical position of the twist detection device 40 can also be adjusted.
