Description

  The present invention relates to a cable winding device and a cable winding method.

  Conventionally, as a gas sensor for detecting a specific gas concentration in a gas to be measured such as exhaust gas, a sensor body including a sensor element, an external connection portion, and a plurality of electrical connections between the sensor body and the external connection portion are electrically connected. A cable including a cable in which lead wires are bundled is known (for example, Patent Document 1).

Japanese Patent Laying-Open No. 2015-172515

  By the way, such a gas sensor may be conveyed in the state which wound up the cable. For example, if the cable is wound only by human manual work, it may be difficult to make the winding diameter constant, and thus there may be variations in the state after winding between the plurality of gas sensors. Therefore, an apparatus capable of winding up the cables of a plurality of gas sensors with the same accuracy is desired. However, a device for winding the cable of the gas sensor has not been known.

  The present invention has been made to solve such a problem, and a main object thereof is to wind up cables of a plurality of gas sensors with high accuracy in the same manner.

  The present invention employs the following means in order to achieve the main object described above.

The cable winding device of the present invention comprises:
Among gas sensors comprising a sensor unit for detecting a specific gas concentration in a gas to be measured, a connector unit having a plurality of electrodes, and a cable for electrically connecting the sensor unit and the connector unit, A first holding part for holding one of the sensor part and the connector part;
A winding unit for winding the cable;
A winding mechanism for winding the cable around the winding unit by rotating the first holding unit so as to go around the winding unit;
It is equipped with.

  In this cable winding device, the first holding part holds one of the sensor part and the connector part of the gas sensor, and the first holding part rotates and moves so that the first holding part rotates around the winding part in this state. By doing so, the cable is wound around the winding portion. Therefore, for example, the cables of a plurality of gas sensors can be wound with high accuracy in the same manner as compared with a case where a human winds the cable only by hand.

  In this case, the cable winding device of the present invention includes a first holding switching unit that switches between holding and releasing the one by the first holding unit, and the first holding unit holding the one. And a control unit that controls the winding mechanism so that the holding operation unit is controlled and the first holding unit rotates and moves.

  The cable winding device of the present invention includes a second holding unit that holds the other of the sensor unit and the connector unit while allowing the other of the sensor unit and the connector unit to move in a direction approaching the winding unit. Also good. If it carries out like this, the 2nd holding | maintenance part can hold | maintain the other, allowing the other movement of a sensor part and a connector part, so that winding of the cable by a winding mechanism may not be inhibited. Therefore, compared with the case where the other is not hold | maintained at the time of winding, for example, it can suppress that the other collides with another object at the time of winding, and can suppress damage of the other.

  In the cable winding device of the present invention, the second holding portion may be configured to apply tension to the cable when the other moves in a direction approaching the winding portion. If it carries out like this, a cable can be wound up by a winding part, preventing a cable from bending by tension | tensile_strength.

  In this case, the direction in which the other approaches the winding part may be a direction intersecting a horizontal plane. If it carries out like this, tension | tensile_strength can be applied to a cable at the time of winding of a cable with the dead weight of a gas sensor. For this reason, for example, a mechanism for outputting power to apply tension to the cable can be omitted, and the deflection of the cable can be suppressed while simplifying the device configuration.

  In the cable winding device according to the aspect of the invention including the second holding portion, the first and second holding portions are inclined with respect to a plane in which a straight line connecting both ends of the cable is perpendicular to the rotation axis direction of the rotational movement. The sensor unit and the connector unit may be held in such a positional relationship. In this way, for example, compared with the case where the straight line connecting both ends of the cable is parallel to the plane perpendicular to the rotational axis direction of the rotational movement, the cables wound on the winding portion overlap each other in the radial direction. Can be suppressed. Therefore, it can suppress that the outer diameter of the wound cable increases.

  In this case, the cable winding device of the present invention connects both ends of the cable by moving at least one of the first holding part and the second holding part along the rotational axis direction of the rotational movement. An inclination angle changing mechanism for changing the angle of the inclination of the straight line may be provided. If it carries out like this, it can suppress that the cables wound up by the winding-up part overlap in a radial direction, or mutually leave | separate too much by adjusting the angle of inclination according to a cable by an inclination-angle changing mechanism.

  In the cable winding device of the present invention, the winding unit has a plurality of winding jigs whose longitudinal direction is disposed along the rotation axis of the rotational movement, and the plurality of winding jigs You may provide the winding diameter change mechanism which changes the winding diameter of the said cable wound up by the said winding part by changing a mutual distance. In this way, the winding diameter can be changed, so that it is easy to wind the cable with a desired winding diameter. In this case, the winding diameter changing mechanism may change the winding diameter by changing the distance between each of the plurality of winding jigs and the rotary shaft of the rotational movement. The winding diameter changing mechanism may change the winding diameter by moving each of the plurality of winding jigs along the radial direction of the rotating shaft.

The cable winding method of the present invention includes a sensor unit for detecting a specific gas concentration in a gas to be measured, a connector unit having a plurality of electrodes, and a cable for electrically connecting the sensor unit and the connector unit. A first holding part for holding one of the sensor part and the connector part, a winding part for winding the cable, and a winding for rotating the first holding part. A cable winding method using a cable winding device provided with a winding mechanism,

  In this cable winding method, similarly to the above-described cable winding device, the cables of a plurality of gas sensors can be wound with high accuracy in the same manner as compared with, for example, a case where a human performs winding only by manual work. . In the cable winding method of the present invention, various aspects of the above-described cable winding device of the present invention may be adopted, and steps for realizing each function of the above-described cable winding device of the present invention are added.

  The rotary shaft 22 is disposed such that the axial direction is along the X-axis, and is rotatably supported by the column 23 via bearings 24 and 24.

  The winding mechanism 30 is a mechanism that rotates and moves the first holding portion 71 that holds the connector portion 14 of the gas sensor 10 so as to turn around the winding portion 48. The winding mechanism 30 includes a winding gear 31, bearings 32 and 32, a belt 34, a rotating plate 35, and a connection member 36. Further, as shown in FIG. 3, the winding mechanism 30 includes a winding motor 33 and a gear 33a. The take-up gear 31 is a disk-like member that is disposed on the left side of the support column 23 coaxially with the rotary shaft 22. The winding gear 31 is attached to the rotary shaft 22 via bearings 32 and 32 and can be rotated independently of the rotary shaft 22. The take-up motor 33 is a drive source of the take-up mechanism 30 and is attached to the front of the column 23 as shown in FIG. The winding motor 33 is configured as a servo motor having a rotational position detector such as an encoder. The gear 33 a is attached to the drive shaft of the winding motor 33. A belt 34 is stretched between the winding gear 31 and the gear 33a. In this embodiment, the belt 34 is a rubber belt. The rotating plate 35 is a disk-shaped member disposed on the left side of the winding gear 31 and coaxially with the rotating shaft 22. A circular through hole is disposed at the center of the rotating plate 35 as viewed from the left, and a first guide member 45 is coaxially attached to the through hole. The 1st holding part 71 is attached to the outer peripheral part of the rotating plate 35, and if the rotating plate 35 rotates, the 1st holding part 71 will also rotate integrally. The connection member 36 is a member that connects the rotating plate 35 and the winding gear 31. The connection member 36 is, for example, a rod-shaped member, and a plurality of connection members 36 are disposed along the circumferential direction of the rotating plate 35 and the winding gear 31 (only two are shown in FIG. 2). The connection member 36 may be a cylindrical member coaxial with the rotation shaft 22. The winding gear 31 and the rotating plate 35 are integrally rotated by the connecting member 36. In the winding mechanism 30, when the winding motor 33 outputs a rotational driving force, the rotational driving force is transmitted to the winding gear 31 via the gear 33 a and the belt 34. Then, the winding gear 31, the rotating plate 35, the connection member 36, and the first holding portion 71 rotate integrally.

  The winding diameter changing mechanism 40 is a mechanism that changes the winding diameter of the cable 16 wound around the winding portion 48 by changing the distance between the plurality of winding jigs 49 included in the winding portion 48. . As shown in FIG. 2, the winding diameter changing mechanism 40 includes a diameter changing gear 41, bearings 42, 42, a diameter changing motor 43, a gear 43a, a belt 44, a first guide member 45, A second guide member 47. The diameter changing gear 41 is a disk-like member that is disposed on the right side of the support column 23 coaxially with the rotary shaft 22. The diameter changing gear 41 is attached to the rotary shaft 22 via bearings 42 and 42, and can rotate independently of the rotary shaft 22. The diameter changing motor 43 is a drive source of the winding diameter changing mechanism 40, and is attached to the column 23 as shown in FIG. The diameter changing motor 43 is configured as a servo motor including a rotational position detector such as an encoder. The gear 43 a is attached to the drive shaft of the diameter changing motor 43. A belt 44 is stretched between the diameter changing gear 41 and the gear 43a. In this embodiment, the belt 44 is a rubber belt. The first guide member 45 is a disk-shaped member having through holes 46 a to 46 d (see FIG. 5), and is attached coaxially to the rotating plate 35 at the center of the rotating plate 35 as described above. The through holes 46 a to 46 d are collectively referred to as the through hole 46. The second guide member 47 is attached to the left end of the rotation shaft 22 coaxially with the rotation shaft 22. The second guide member 47 is a disk-shaped member having grooves 47a to 47d (see FIG. 5). In the winding diameter changing mechanism 40, the diameter changing gear 41 is rotated by the rotational driving force from the diameter changing motor 43 in a state where the first clutch 50 is off and the second clutch 60 is on (state shown in FIG. 4). When rotating, the rotating shaft 22 and the second guide member 47 rotate via the diameter changing gear 41 and the second clutch 60. Although details will be described later, the rotation of the rotation shaft 22 causes the second guide member 47 to rotate relative to the first guide member 45 (the rotation position of the second guide member 47 with respect to the first guide member 45 is shifted). Thus, the winding diameter of the winding unit 48 is changed. The rotating shaft 22 and the second clutch 60 that is turned on, which will be described later, also constitute a part of the winding diameter changing mechanism 40.

  The winding unit 48 is a member for winding the cable 16 of the gas sensor 10. The winding unit 48 includes winding jigs 49a to 49d. The winding jigs 49a to 49d are collectively referred to as a winding jig 49. Each of the winding jigs 49a to 49d is a substantially cylindrical member, and is disposed such that the longitudinal direction (axial direction) is along the X axis. The winding jigs 49 a to 49 d are arranged at equal intervals along the circumferential direction of the first guide member 45. As shown in FIGS. 2 and 5, each of the winding jigs 49 a to 49 d has a right end portion inserted into each of the grooves 47 a to 47 d of the second guide member 47. Thereby, each of the winding jigs 49a to 49d is slidable along each of the grooves 47a to 47d. Further, each of the winding jigs 49 a to 49 d passes through each of the through holes 46 a to 46 d of the first guide member 45 disposed on the left side of the second guide member 47, and is on the left side of the first guide member 45. Protruding. A portion of the winding jigs 49 a to 49 d that protrudes to the left of the first guide member 45 winds up the cable 16.

  Here, each of the through holes 46a to 46d of the first guide member 45 has a substantially rectangular shape (a rounded rectangle in the present embodiment) whose longitudinal direction is along the radial direction of the first guide member 45 when viewed from the left side. doing. Each of the through holes 46a to 46d has substantially the same width as the winding jigs 49a to 49d. The through holes 46a to 46d are shaped so as to be rotationally symmetric as a whole (here, four-fold symmetric) when viewed from the left. Each of the winding jigs 49a to 49d is movable in the radial direction of the first guide member 45 along each of the through holes 46a to 46d. Further, in the groove 47a of the second guide member 47, the portion farthest from the central axis of the second guide member 47 and the closest portion are shifted in the circumferential direction of the second guide member 47, and both portions are arcuate. It has a shape that is connected by a curved line. The grooves 47b to 47d have the same shape as the groove 47a, and the grooves 47a to 47d have a shape that is rotationally symmetric as a whole (here, four-fold symmetric) as viewed from the left. Thus, the through holes 46a to 46d and the grooves 47a to 47d are different in shape, and the positions of the winding jigs 49a to 49d are regulated by the positional relationship between the through holes 46a to 46d and the grooves 47a to 47d. It has come to be. For example, the position of the winding jig 49a is regulated by the through hole 46a and the groove 47a, and is positioned at a portion where the through hole 46a and the groove 47a overlap when viewed from the left. The same applies to the winding jigs 49b to 49d. Therefore, when the rotational position of the second guide member 47 with respect to the first guide member 45 is shifted, that is, when the positional relationship between the through holes 46a to 46d and the grooves 47a to 47d is changed, each of the winding jigs 49a to 49d is the first. The distance from the center of the guide member 45 changes, and the winding diameter of the winding part 48 is changed. For example, in FIG. 5A, the portion farthest from the central axis of the first guide member 45 among the through holes 46 a to 46 d and the most central portion of the second guide member 47 among the grooves 47 a to 47 d in the left view. The 1st guide member 45 and the 2nd guide member 47 are located so that a distant part may overlap. In this state, each of the winding jigs 49a to 49d is also located at a portion farthest from the central axis of the first guide member 45 and the second guide member 47, and the winding diameter of the winding portion 48 (here, The diameter of a circle that surrounds and touches all of the winding jigs 49a to 49d is in a maximum state. When the second guide member 47 rotates counterclockwise from this state, the overlapping portions of the through holes 46a to 46d and the grooves 47a to 47d change as shown in FIG. Each of 49d approaches the central axis of the 1st guide member 45, and a winding diameter becomes small. Thus, the winding diameter of the cable 16 can be changed by changing the rotational position of the second guide member 47 with respect to the first guide member 45. Although not particularly limited, the winding diameter may be adjustable, for example, between 50 mm and 105 mm.

  The first clutch 50 is a mechanism that switches whether or not rotational power is transmitted between the winding gear 31 and the rotary shaft 22. The first clutch 50 includes a small diameter member 51, a piston 52, a pressing member 53, and a large diameter member 54. The small diameter member 51 is a substantially cylindrical member attached coaxially to the rotation shaft 22 and rotates integrally with the rotation shaft 22. The large diameter member 54 is a substantially cylindrical member attached to the winding gear 31 so as to be coaxial with the rotary shaft 22 and the small diameter member 51, and rotates integrally with the winding gear 31. The piston 52 is a rod-shaped member arranged in a plurality (only two are shown in FIG. 2) along the circumferential direction of the small diameter member 51. The pressing member 53 is a substantially disk-shaped member attached to the left end of the plurality of pistons 52. The pressing member 53 is disposed so that the rotation shaft 22 passes through the center and is coaxial with the rotation shaft 22. The small-diameter member 51 and the piston 52 are configured as an air cylinder that operates with or without air pressure. Specifically, the piston 52 is pressed to the left by an elastic member such as a spring (not shown) disposed inside the small diameter member 51. Further, when air pressure is supplied into the small diameter member 51 via the winding gear 31 and the passage 58 disposed in the large diameter member 54, the pressure is applied to the elastic member in the small diameter member 51. The piston 52 moves to the right side by overcoming. Thereby, in a state where pressure is supplied in the passage 58, the plurality of pistons 52 and the pressing member 53 move to the right side, so that the pressed member 54a located on the left side of the pressing member 53 in the large diameter member 54. And the pressing member 53 are separated from each other to the left and right, and no rotational power is transmitted between them (FIG. 4). In the state of FIG. 4 (also referred to as an off state), the large-diameter member 54 and the small-diameter member 51 rotate independently of each other, and the winding gear 31 and the rotating shaft 22 also rotate independently of each other. On the other hand, in a state where air is not supplied into the small diameter member 51 through the passage 58, the plurality of pistons 52 and the pressing member 53 move to the left side, and the pressing member 53 presses the pressed member 54a (FIG. 2). ). In the state of FIG. 2 (also referred to as an on state), the pressing member 53 presses the pressed member 54a, so that rotational power is transmitted between them, and both rotate integrally. Therefore, the rotary shaft 22 and the winding gear 31 rotate integrally through the pressing member 53 and the large diameter member 54. The pressing member 53 and the pressed member 54a may be configured to rotate integrally by a static frictional force, or may be rotated integrally by engagement of convex portions provided on both members. It may be configured.

The pressure switching unit 55 includes an X-axis cylinder 56 and a moving block 57. The X-axis cylinder 56 and the moving block 57 are arranged in a space provided inside the support column 23 and are located to the right of the winding gear 31. The X-axis cylinder 56 is configured as an air cylinder, for example, and moves the moving block 57 in the X-axis direction (left and right) by moving the piston rod along the X-axis direction. The moving block 57 includes a pipe 57a. The pipe 57a is configured to be able to supply air from a pressure supply source (not shown). As shown in FIGS. 2 and 3, when the X-axis cylinder 56 moves the moving block 57 to the left while the first holding portion 71 is positioned at the upper end of the rotating plate 35, the moving block 57 is moved to the winding gear 31. The pipe 57a and the passage 58 communicate with each other. As a result, air pressure is supplied to the passage 58, and the first clutch 50 enters the off state described above. On the other hand, when the X-axis cylinder 56 moves the moving block 57 to the right side, the moving block 57 and the take-up gear 31 are separated from each other, so that no air pressure is supplied to the passage 58 and the first clutch 50 is turned on as described above. As described above, the pressure switching unit 55 switches between the on state and the off state of the first clutch 50 by switching the presence or absence of the pressure in the passage 58.

  The second clutch 60 is a mechanism for switching whether or not rotational power is transmitted between the diameter changing gear 41 and the rotary shaft 22. The second clutch 60 is configured as an electromagnetic clutch, for example, and includes a main body portion 61 and an armature 62. The main body 61 is a substantially cylindrical member attached to the diameter changing gear 41 so as to be coaxial with the rotating shaft 22, and rotates integrally with the diameter changing gear 41. The armature 62 is attached coaxially to the rotating shaft 22 and rotates integrally with the rotating shaft 22. The main body 61 has a coil (not shown) inside. When the coil is energized, the armature 62 is attracted to the main body 61 and the main body 61 and the armature 62 are engaged with each other (see FIG. FIG. 4). In the state of FIG. 4 (also referred to as an on state), the main body 61 and the armature 62 are engaged to transmit rotational power between the two, and both rotate integrally. Therefore, the diameter changing gear 41 and the rotating shaft 22 rotate integrally through the second clutch 60. On the other hand, when the coil of the diameter changing gear 41 is not energized, the armature 62 is pulled to the left side by the elastic force of a spring (not shown) of the second clutch 60, so that the main body 61 and the armature 62 are moved to the left and right. They are separated and no rotational power is transmitted between them (FIG. 2). In the state of FIG. 2 (also referred to as an off state), the diameter changing gear 41 and the rotating shaft 22 rotate independently of each other.

The rear clamping unit 72 is attached to the rotating plate 35 via a fixing member 76. The front clamping unit 72 is attached to the operated unit 74. The spring 73 is an elastic member having both ends attached to the sandwiching portions 72 and 72, respectively, and applies tension to the sandwiching portions 72 and 72 in a direction in which they approach each other in the Y-axis direction. The first holding portion 71 holds the connector portion 14 disposed between the holding portions 72 and 72 by the holding portions 72 and 72 by the tension of the spring 73. The operated portion 74 is movable back and forth along a Y-axis rail 75 disposed on the left side of the fixed member 76. The operated portion 74 has a portion projecting upward and a portion projecting further to the right from the upper end of the portion. When the portion projecting to the right is pressed forward, the operated portion 74 follows the Y-axis rail 75. To move forward. As the operated portion 74 moves, the front clamping unit 72 also moves forward. The fixing member 76 is located on the right side of the rotating plate 35 and is attached to the rotating plate 35 in the vicinity of the upper end of the rotating plate 35 in FIGS. Thereby, the rotating plate 35 and the 1st holding | maintenance part 71 rotate integrally.

The Y-axis cylinder 77b is configured as an air cylinder, for example, and moves the operated portion 74 rearward by moving the piston rod along the Y-axis direction. The operated portion 74 rotates together with the rotating plate 35. However, when the operated portion 74 is at a predetermined position (here, the position shown in FIGS. 2 and 3), the operated portion 74 is movable by the Y-axis cylinder 77b.

  The 2nd holding part 81 is a mechanism holding the other of sensor part 12 and connector part 14 among gas sensors 10, and holds sensor part 12 in this embodiment. The second holding part 81 is located below the first holding part 71 and the winding part 48. The second holding portion 81 includes sandwiching portions 82 and 82 and a Z-axis rail 83. The clamping parts 82 and 82 are, for example, plate-like members, and are disposed at the front and back of each other. In the present embodiment, the clamping portions 82 and 82 are not movable, and the sensor portion 12 is held by fitting a part of the sensor portion 12 (here, the flange portion) into the concave portions of the clamping portions 82 and 82. However, at least one of the sandwiching portions 82 and 82 is movable back and forth, and the second holding portion 81 is a spring (not shown) that applies tension to the sandwiching portions 82 and 82 in a direction in which they approach each other in the Y-axis direction. The clamping portions 82 and 82 may hold the sensor portion 12 by the tension of the spring. Further, the second holding unit 81 has a switching mechanism for switching between holding and releasing of the sensor unit 12 by moving at least one of the holding units 82 and 82 (for example, moving back and forth or rotating). May be. This switching mechanism may be a mechanism that moves at least one of the clamping portions 82 and 82 by air pressure, such as an air cylinder. The Z-axis rail 83 is attached to the support column 84. The clamping portions 82 and 82 can move up and down along the Z-axis rail 83. Thus, the second holding unit 81 holds the sensor unit 12 while allowing the sensor unit 12 to move up and down. As shown in FIG. 2, the holding parts 82, 82 of the second holding part 81 are not directly below the holding parts 72, 72 of the first holding part 71, but are positioned below the holding parts 72, 72 and to the left. Has been placed. As a result, the first and second holding portions 71 and 81 have a plane (YZ here) in which a straight line connecting both ends of the cable 16 is perpendicular to the rotation axis direction (here, the X axis direction) of the first holding portion 71. The sensor unit 12 and the connector unit 14 are held in a positional relationship that is inclined with respect to the plane. That is, an angle θ1 formed by a straight line connecting the end on the sensor unit 12 side and the end on the connector unit 14 side of the cable 16 (a straight line along the cable 16 in FIG. 2) and the YZ plane exceeds 0 ° 90. The arrangement of the first holding part 71 and the second holding part 81 is determined so as to be less than 0 °. The formed angle θ1 may be 45 ° or less or 30 ° or less.

  The control device 90 is an example of a control unit. The control device 90 is configured as a microprocessor centered on a CPU, and includes a ROM that stores processing programs, a RAM that is used as a work area, an HDD that stores various data, and the like. The control device 90 controls the entire cable winding device 20. A display unit 91 such as an LCD and an operation unit 92 such as a keyboard and a mouse are connected to the control device 90. The control device 90 outputs control signals to the winding motor 33, the diameter changing motor 43, the X-axis cylinder 56, the second clutch 60, the X-axis cylinder 77a, the Y-axis cylinder 77b, and the display unit 91. Further, the control device 90 inputs a position detection signal from the winding motor 33 and the diameter changing motor 43, an operation signal from the operation unit 92, and the like.

Next, operation | movement of the cable winding apparatus 20 comprised in this way is demonstrated. The cable winding method by the cable winding device 20 is as follows:
(A) the first holding unit 71 holds one of the sensor unit 12 and the connector unit 14 (here, the connector unit 14);
(B) a step of causing the winding unit 48 to wind the cable 16 by rotating the first holding unit 71 so that the winding mechanism 30 rotates around the winding unit 48;
including.

  The cable take-up device 20 adjusts the take-up diameter of the take-up portion 48 as necessary before performing step (a). For example, when information specifying the winding diameter is input from the operator via the operation unit 92, the control device 90 adjusts the winding diameter based on the acquired information. First, the control device 90 controls the first clutch 50 and the second clutch 60 so that the first clutch 50 is turned off and the second clutch 60 is turned on as shown in FIG. The controller 90 operates the X-axis cylinder 56 of the pressure switching unit 55 to supply pressure to the passage 58, thereby turning off the first clutch 50. The control device 90 turns on the second clutch 60 by energizing the coil of the main body 61. Then, the control device 90 rotates the diameter changing motor 43 in this state. Thus, the rotational driving force from the diameter changing motor 43 is transmitted to the second guide member 47 via the diameter changing gear 41, the second clutch 60, and the rotating shaft 22, and the second guide member 47 rotates. On the other hand, since the first clutch 50 is in the off state, the rotational driving force from the diameter changing motor 43 is not transmitted to the rotary plate 35 and the first guide member 45. As a result, the rotational position of the second guide member 47 with respect to the first guide member 45 is changed as described above, and the winding diameter of the cable 16 is changed. The control device 90 controls the rotation amount of the diameter changing motor 43 to rotate the second guide member 47 so that the specified winding diameter is obtained. When changing the winding diameter, the control device 90 may operate an electromagnetic brake provided in the winding motor 33 so that the first guide member 45 does not rotate. Here, the following description will be given by taking as an example a case where the winding diameter of the winding unit 48 is adjusted to the maximum state.

  When the winding diameter is adjusted, the controller 90 first prepares the first clutch 50 so that the first clutch 50 is turned on and the second clutch 60 is turned off as shown in FIG. The clutch 50 and the second clutch 60 are controlled. In this state, the rotational driving force from the diameter changing motor 43 is not transmitted to the rotary shaft 22. Further, the rotational driving force from the winding motor 33 is transmitted not only to the rotating plate 35 and the first holding portion 71 but also to the second guide member 47 via the first clutch 50 and the rotating shaft 22. The Thereby, not only the rotating plate 35, the first guide member 45, and the first holding portion 71 rotate integrally, but also the second guide member 47 and the winding portion 48 rotate integrally therewith. Therefore, in this state, the positional relationship between the first guide member 45 and the second guide member 47 does not shift. Then, the control device 90 rotates the winding motor 33 as necessary to move the first holding unit 71 to a predetermined position shown in FIGS. That is, the control device 90 puts the first holding unit 71 into a state that can be switched by the first holding switching unit 77 (FIGS. 2, 3, and 6 (a)).

  When preparation for step (a) is performed, the control device 90 first moves the Y-axis cylinder 77b to the left by the X-axis cylinder 77a as step (a) (FIG. 6B). Subsequently, the control device 90 moves the operated portion 74 rearward by the X-axis cylinder 77a (FIG. 6C). As a result, the distance between the sandwiching portions 72 and 72 is increased to be in a released state, and the connector portion 14 can be inserted between the sandwiching portions 72 and 72. Then, after the connector portion 14 is inserted, the control device 90 operates the X-axis cylinder 77a and the Y-axis cylinder 77b to release the rearward movement of the operated portion 74 (FIG. 6 (d)). As a result, the operated portion 74 and the front holding portion 72 are moved rearward by the tension of the spring 73, and the connector portion 14 is held between the holding portions 72 and 72. The insertion of the connector portion 14 between the holding portions 72 and 72 may be performed by the robot arm, for example, by controlling the robot arm (not shown) provided in the cable winding device 20 by the control device 90. Or an operator may insert the connector part 14 between the clamping parts 72 and 72. The orientation of the connector portion 14 held between the sandwiching portions 72 and 72 is preferably adjusted to be a predetermined orientation. That is, when winding the cable 16 sequentially for the plurality of gas sensors 10, it is preferable that the orientation of the connector portion 14 is always the same. In the present embodiment, the predetermined direction is determined as the direction in which the connector 14a faces forward, as shown in FIG. 6 (d).

  After step (a), as shown in FIG. 2, a step is performed in which the second holding unit 81 is held by the sensor unit 12. This step may be performed by the control device 90 controlling the robot arm or by an operator, as in the insertion of the connector unit 14 into the holding units 72 and 72. In this state, as described above, the angle formed by the straight line connecting the end on the sensor unit 12 side and the end on the connector unit 14 side of the cable 16 (the straight line along the cable 16 in FIG. 2) and the YZ plane. θ1 is greater than 0 ° and less than 90 °. In this state, the sandwiching portions 82 and 82 are preferably positioned slightly above the lowermost end of the upper and lower movement range along the Z-axis rail 83. Thereby, in the state before the start of winding in step (b), tension is applied to the cable 16 due to its own weight of the sensor unit 12 and the sandwiching units 82 and 82, and the cable 16 extends without bending.

  The above-described step (a), adjustment of the winding diameter, and holding of the sensor unit 12 by the second holding unit 81 may be performed in a reversed order.

  Next, the control device 90 performs step (b). In other words, the control device 90 rotates the winding motor 33 while the first clutch 50 is in the on state and the second clutch 60 is in the off state. FIG. 7 is an explanatory view showing a state in which the cable 16 is taken up by the take-up portion 48. 7A is the same state as FIG. 2, that is, the state at the start of winding, FIG. 7B is a state in which the first holding portion 71 is rotated 90 ° clockwise, and FIG. FIG. 7D is an explanatory diagram of a state in which the first holding unit 71 is rotated by 180 °, and FIG. When the control device 90 rotates the winding motor 33, the first holding portion 71, the rotating plate 35 and the winding portion 48 are rotated from the state shown in FIG. As the portion 14 also rotates, the cable 16 is wound around the winding portion 48 (FIGS. 7B to 7D). At this time, since the sandwiching portions 82 and 82 can be moved upward by the Z-axis rail 83, the sandwiching portions 82 and 82 and the sensor portion 12 also move upward as the cable 16 is wound. At this time, the cable 16 is tensioned by the weight of the sensor unit 12 and the clamping units 82 and 82. FIG. 7D shows a state where the first holding portion 71 is rotated once, that is, a state where the number of turns of the cable 16 is 1. The control device 90 may rotate the first holding unit 71 two or more times as necessary, so that the number of turns of the cable 16 is two or more. Although not particularly limited, the number of turns of the cable 16 may be variable between values 1 to 3. For example, the control device 90 may input information specifying the number of turns from the operator via the operation unit 92, determine the number of turns based on the input information, and determine the number of times to rotate the first holding unit 71. Good. In this embodiment, the number of turns in step (b) is set to 1.

  FIG. 8 is an explanatory diagram showing the state of the cable 16 when winding is completed. FIG. 8 corresponds to a front view of the state of FIG. As shown in FIG. 8, the cable 16 is spirally wound around the winding portion 48, and the cables 16 wound around the winding portion 48 do not overlap in the radial direction. That is, the cable 16 is not wound around the cable 16 wound around the winding portion 48. As shown in FIG. 2, the first holding portion 71 and the second holding portion 81 are arranged so that the angle θ1 formed is greater than 0 ° and less than 90 °, so that the cable 16 is spirally formed in this way. Easy to wind up. The angle θ2 formed by the portion of the cable 16 wound around the winding portion 48 and the YZ plane shown in FIG. 8 may be, for example, greater than 0 ° and less than the angle θ1 formed.

  When the control device 90 completes winding the cable 16 of the gas sensor 10 as described above, the gas sensor 10 is removed. For example, after the operator bundles the portion of the cable 16 wound around the winding unit 48 with a binding band or the like, the control device 90 controls the first holding switching unit 77 to release the clamping units 72 and 72. As shown in FIG. 6C, the operator removes the cable 16 from the winding unit 48 and removes the gas sensor 10. At least one of the work of bundling the cable 16 and the work of removing the gas sensor 10 may be automatically performed by the control device 90 using a robot arm or the like. The removed gas sensor 10 is sequentially accommodated in, for example, the transfer tray 95 shown in FIG. The cable winding device 20 sequentially winds the cable 16 for the plurality of gas sensors 10. The transport tray 95 shown in FIG. 9 is provided with first to third storage portions 95a to 95c that are recesses that can store the sensor portion 12, the connector portion 14, and the cable 16. A plurality of first and second storage portions 95a and 95b are provided corresponding to the number of gas sensors 10 that can be stored (here, 5). The third storage unit 95 c is common to the plurality of gas sensors 10. When the gas sensor 10 is stored in the transfer tray 95 as described above, it may not be stored properly unless the cables 16 of the plurality of gas sensors 10 are wound up in the same manner. For example, when the orientation of the connector portion 14 with respect to the winding portion of the cable 16 is rotated by 90 ° about the axis of the cable 16 (a state in which the connector 14a faces the front side in FIG. 9), the connector portion 14 may not fit in the first storage portion 95a, or the connector portion 14 may protrude from the transport tray 95 toward the front side of the sheet. Alternatively, when the winding diameter of the cable 16 is different between the plurality of gas sensors 10, the length of the cable 16 other than the wound portion, that is, the length of the connection portion between the wound portion and the sensor unit 12. In addition, the length of the connection portion between the wound portion and the connector portion 14 may be different among the plurality of gas sensors 10. In such a case, depending on the length of the connection portion, at least one of the sensor unit 12 and the connector unit 14 may not be stored in the corresponding first and second storage units 95a and 95b. For example, when the cable 16 is wound only by an operator's manual work, these states are likely to occur. On the other hand, in the cable winding device 20 of this embodiment, it is easy to always wind the cable 16 with a constant winding diameter or to make the connector portion 14 have the same direction. Therefore, it is easy to accommodate the gas sensor 10 in the transfer tray 95.

  According to the cable winding device 20 of the present embodiment described in detail above, the first holding portion 71 holds one of the sensor portion 12 and the connector portion 14 (here, the connector portion 14) of the gas sensor 10, and in that state. The winding mechanism 30 rotates and moves the first holding unit 71 so that the first holding unit 71 rotates around the winding unit 48, thereby winding the cable 16 on the winding unit 48. Thereby, compared with the case where a person winds up the cable 16 only by manual work, for example, the cable 16 of the some gas sensor 10 can be wound up with sufficient accuracy similarly.

  In addition, the cable winding device 20 allows the other of the sensor unit 12 and the connector unit 14 (here, the sensor unit 12) to move in a direction approaching the winding unit 48 (here, substantially upward). A second holding part 81 that holds the part 12 is provided. Thereby, the 2nd holding | maintenance part 81 can hold | maintain the sensor part 12, preventing the winding of the cable 16 by the winding mechanism 30 by accept | permitting the movement of the sensor part 12. FIG. Therefore, for example, compared with the case where the sensor unit 12 is not held at the time of winding, the sensor unit 12 can be prevented from colliding with another object at the time of winding, and damage to the sensor unit 12 can be suppressed.

  Further, the second holding unit 81 is configured to apply tension to the cable 16 when the sensor unit 12 moves in a direction approaching the winding unit 48 (here, substantially upward). Therefore, the cable 16 can be wound up by the winding portion 48 while preventing the cable 16 from being bent by tension. Moreover, the second holding portion 81 is positioned below the winding portion 48, and the direction in which the sensor portion 12 approaches the winding portion 48 (here, substantially upward) intersects the horizontal plane (here, the XY plane). Direction. Thereby, tension can be applied to the cable 16 when the cable 16 is wound up by its own weight. Therefore, the cable winding device 20 of the present embodiment omits a mechanism that outputs power, for example, to apply tension to the cable 16 (for example, a mechanism that outputs power that applies a downward force to the second holding portion 81). doing. Thereby, the bending of the cable 16 can be suppressed while simplifying the device configuration of the cable winding device 20.

  Furthermore, the first and second holding portions 71 and 81 are inclined with respect to a plane (here, the YZ plane) in which the straight line connecting both ends of the cable 16 is perpendicular to the rotation axis direction of the rotational movement of the first holding portion 71. The sensor unit 12 and the connector unit 14 are held in such a positional relationship. Thereby, for example, compared with the case where the straight line connecting both ends of the cable 16 is parallel to the YZ plane (when the angle θ1 formed in FIG. 2 is 0 °), the cable 16 wound around the winding portion 48 is used. It can suppress that each other overlaps in the radial direction. Therefore, it can suppress that the outer diameter of the wound cable 16 increases.

  In addition, the winding unit 48 includes a plurality of winding jigs 49 whose longitudinal direction is disposed along the rotational axis of the rotational movement of the first holding unit 71. The cable winding device 20 includes a winding diameter changing mechanism 40 that changes the winding diameter of the cable 16 wound around the winding portion 48 by changing the distance between the plurality of winding jigs 49. ing. Thereby, since the winding diameter of the cable 16 can be changed, it is easy to wind the cable 16 with a desired winding diameter.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the embodiment described above, the cable winding device 20 includes the winding diameter changing mechanism 40. However, the present invention is not limited to this, and the winding diameter may be always fixed. Alternatively, the cable winding device 20 may be configured so that an operator can change the winding diameter without providing the winding diameter changing mechanism 40.

  In the above-described embodiment, the winding unit 48 includes the four winding jigs 49, but is not limited thereto. For example, the number of winding jigs 49 may be determined according to the flexibility of the cable 16. However, the number of winding jigs 49 is preferably 3 or more, and more preferably 4 or more. Further, if the winding diameter is not changed, the winding portion 48 does not need to include a plurality of winding jigs 49. For example, the winding portion 48 may be a columnar member having the same outer shape as the winding diameter. .

  In the embodiment described above, the arrangement of the first holding portion 71 and the sandwiching portion 82 is determined so that the angle θ1 formed in FIG. 2 is greater than 0 ° and less than 90 °. However, the angle θ1 is not limited to this. The arrangement of the first holding unit 71 and the second holding unit 81 may be determined so as to be 0 °. For example, the arrangement of the first holding unit 71 and the second holding unit 81 may be determined so as to hold the sensor unit 12 directly below the connector unit 14.

  In the embodiment described above, the first holding unit 71 holds the connector unit 14 and the second holding unit 81 holds the sensor unit 12. However, the present invention is not limited to this, and the holding unit may be reversed. Further, the cable winding device 20 may not include the second holding portion 81.

  In the embodiment described above, the second holding portion 81 is movable up and down, so that when the cable 16 is wound around the winding portion 48, the cable 16 is tensioned by the weight of the sensor portion 12 and the holding portions 82 and 82. However, it is not limited to this. For example, the cable winding device 20 may include a mechanism that outputs power for applying a force to the second holding unit 81 in a direction away from the winding unit 48 (for example, downward). For example, the second holding unit 81 may include a moving mechanism such as a slider that outputs power and moves the holding units 82 and 82 up and down along the Z-axis rail 83. The moving mechanism may include a power output mechanism such as a combination of a motor and a ball screw. In this case, a mechanism for interlocking the rotation speed of the winding unit 48 by the winding motor 33 and the rising speed of the second holding unit 81 by the power output mechanism may be further provided. Alternatively, the control device 90 may control the winding motor 33 and the power output mechanism so that the rotation speed of the winding unit 48 and the rising speed of the second holding unit 81 are interlocked. The tension applied to the cable 16 can be adjusted to an appropriate value according to the rotational speed of the winding unit 48 by interlocking the rotational speed of the winding unit 48 with the rising speed of the second holding unit 81. Thereby, compared with the case where tension is applied to the cable 16 only by the own weight of the sensor unit 12 and the sandwiching parts 82 and 82, the deflection of the cable 16 due to its own weight being too light is further suppressed, or the own weight is too heavy. The excessive pulling of the cable 16 can be further suppressed. Further, in the case where no tension is applied to the cable 16 due to the weight of the sensor unit 12 and the clamping units 82 and 82, the direction in which the clamping units 82 and 82 allow the sensor unit 12 to move may be parallel to the horizontal plane. For example, in the cable winding device 20, the rotation axis of the first holding unit 71 and the longitudinal direction of the winding unit 48 are along the vertical direction, and the first holding unit 71 and the second holding unit 81 are on the same horizontal plane. The second holding unit 81 may be configured to allow the sensor unit 12 to move in the horizontal direction as the cable 16 is wound.

  In the embodiment described above, the take-up diameter changing mechanism 40 changes the take-up diameter of the take-up portion 48 by shifting the position (rotational position) of the second guide member 47 with respect to the first guide member 45. However, the winding diameter of the winding unit 48 may be changed by any mechanism. Further, the shapes of the through holes 46a to 46d and the grooves 47a to 47d are not limited to the above-described embodiments. For example, the shape of the through holes 46a to 46d and the shape of the grooves 47a to 47d in the left side view may be reversed from the above-described embodiment. Or it is good also considering the shape of the left view of the groove | channels 47a-47d as a substantially rectangular shape (for example, rectangular shape of a rounded corner). Also in this case, if each of the grooves 47 a to 47 d has a shape in which the portion farthest from the central axis of the second guide member 47 and the nearest portion are shifted in the circumferential direction of the second guide member 47, the above description is given. The winding diameter can be changed in the same manner as in the above embodiment.

  In the embodiment described above, the cable winding device 20 rotates the winding unit 48 integrally with the first holding unit 71, but is not limited thereto. For example, the winding unit 48 may not be rotated.

  In the embodiment described above, the first clutch 50 is configured to switch between the on state and the off state depending on the presence or absence of air pressure, but is not limited thereto. For example, the first clutch 50 may be an electromagnetic clutch similar to the second clutch 60.

  In the above-described embodiment, the angle θ1 formed by the arrangement of the first holding unit 71 and the second holding unit 81 is fixed, but is not limited thereto. The cable winding device 20 is configured to change the angle θ1 formed by moving at least one of the first holding unit 71 and the second holding unit 81 along the rotational axis direction of the rotational movement of the first holding unit 71. An angle changing mechanism may be provided. For example, you may employ | adopt the cable winding apparatus 20A of the modification shown in FIG. The cable winding device 20A includes a second holding unit moving mechanism 85 (an example of an inclination angle changing mechanism) in addition to the components of the cable winding device 20 described above. The second holding portion moving mechanism 85 is disposed between the holding portions 82 and 82 and the rail 83. The second holding portion moving mechanism 85 includes, for example, a motor and a ball screw, and moves the holding portions 82 and 82 in the left-right direction with respect to the rail 83. Further, the second holding portion moving mechanism 85 can move up and down along the rail 83, whereby the holding portions 82 and 82 also move up and down integrally with the second holding portion moving mechanism 85. The 2nd holding | maintenance part moving mechanism 85 changes angle | corner (theta) 1 made by moving the clamping parts 82 and 82 right and left. Here, the angle θ2 formed after winding shown in FIG. 8 varies depending on the angle θ1 formed before winding and the length of the cable 16. If the formed angle θ2 is too small, the cables 16 wound around the winding portion 48 may overlap each other in the radial direction. If the formed angle θ2 is too large, the cable 16 wound around the winding portion 48 may be used. Sometimes they are too far apart. By appropriately adjusting the angle θ1 formed by the second holding unit moving mechanism 85 according to the cable 16 (for example, according to the length and thickness of the cable 16), the angle θ2 formed can be adjusted appropriately. For example, the control device 90 may adjust the angle θ1 formed by controlling the second holding unit moving mechanism 85 based on information such as the length and thickness of the cable 16. Further, the control device 90 may adjust the inclination angle of the cable 16 by controlling the second holding unit moving mechanism 85 during winding. In the cable winding device 20A of FIG. 10, the angle θ1 formed by the second holding unit moving mechanism 85 is adjusted. For example, a mechanism similar to the second holding unit moving mechanism 85 is used as the holding units 72 and 72 of the first holding unit 71. The first holding portion 71 (particularly, the holding portions 72 and 72) may be moved in the left-right direction by this mechanism. Even in this case, the formed angle θ1 can be changed.

  INDUSTRIAL APPLICABILITY The present invention can be used in the manufacturing industry of gas sensors that detect the concentration of a specific gas such as NOx in a gas to be measured such as automobile exhaust gas.
