In addition, a plurality of the reels are provided, and an electric wire selection / supply unit that allows electric wires to be selectively supplied from the reels. Thereby, a plurality of types of electric wires can be appropriately switched and cut to a predetermined length.

  The configuration of the electric wire scale cutting unit 23 itself that selectively supplies a plurality of types of electric wires and cuts them into a predetermined length of electric wire is, for example, a well-known configuration disclosed in JP-A-9-306257 Etc. can be adopted.

  The wire stripping unit 24 strips the end portion of the wire W, and includes, for example, a pair of stripping blades that can be moved close to and away from each other, and an advancing / retreating drive unit that drives the stripping blades to advance and retract toward the end of the wire W. The structure which has can be employ | adopted. Then, the pair of stripping blades are moved toward the end of the electric wire conveyed to the electric wire stripping section 24, and the pair of stripping blades are cut into the covering portion of the electric wire W. The covering part at the end of the electric wire W is peeled off by moving it toward.

<2. Electric wire discharging device>
The electric wire discharge device 30 will be described. 2 is a schematic front view showing the wire discharge device 30 according to the embodiment, FIG. 3 is a schematic plan view showing the bar supply mechanism 40 of the wire discharge device 30, and FIG. 3 is a schematic side view showing a bar supply mechanism 40. FIG.

  The wire discharging device 30 discharges the terminal-attached electric wire 18 in a state where the end of the electric wire (here, the electric wire 18 with terminal) is held by the electric wire holding bar 10 provided with the plurality of electric wire holding portions 14. The wire end holding and setting unit 32 and the bar supply mechanism 40 are provided. The bar supply mechanism 40 includes a bar support portion 50, a movable support mechanism 55, and a drive mechanism 70.

  The bar support portion 50 is configured to be able to support the wire holding bar 10 in which the plurality of wire holding portions 14 are arranged in a straight line, and the movable support mechanism 55 moves the bar supporting portion 50 to the wire receiving position. The drive mechanism 70 is configured to reciprocate between the wire receiving position RP and the extraction position TP, and is supported so as to be reciprocally movable between the RP and the extraction position TP. In addition, the wire end holding set portion 32 can sequentially set the end portions of the terminal-attached wires 18 to the plurality of wire holding portions 14 of the wire holding bar 10 supported by the bar support portion 50 at the wire receiving position RP. It is configured.

  Here, the electric wire holding bar 10 for setting the end of the terminal-attached electric wire 18 will be described. FIG. 5 is a front view showing the electric wire holding bar 10, and FIG. 6 is a plan view showing the electric wire holding bar 10.

  The electric wire holding bar 10 includes a main body portion 12, a plurality of electric wire holding portions 14, and a side plate portion 16.

  The main body 12 is formed in the shape of a long bar, and a plurality of holding recesses 12a are formed on the upward one side surface 12f side portion extending along the longitudinal direction at intervals along the longitudinal direction. . Each holding recess 12a is formed in a groove shape that opens on the one side surface 12f of the main body portion 12 and on both side surfaces adjacent to the one side surface, and the opening end portion on the one side surface 12f side is from the base end side. Is also narrowing.

  In addition, guide holes 12 g that open outward are formed at both ends of the main body 12. By inserting an upper roller 64 and a lower roller 65 described later into the guide hole 12g, the wire holding bar 10 is supported at a fixed position at the wire receiving position RP.

  Each electric wire holding portion 14 is a member configured to be able to hold an end portion of the terminal-attached electric wire 18. Here, the electric wire holding part 14 is formed by bending a metal plate having elasticity, and has a fixed end part 14a and a holding part 14b, and a portion between them is the fixed end part 14a and the holding part. It is formed narrower than 14b. Then, by inserting the fixed end portion 14a so as to fit into the holding recess 12a, the wire holding portion 14 is in the posture in which the holding portion 14b protrudes from the one side surface 12f of the main body portion 12. It is fixedly held against. Further, by inserting and fitting the plurality of wire holding portions 14 in the holding recesses 12a in the same manner, the plurality of wire holding portions 14 are supported in parallel along the longitudinal direction with respect to the main body portion 12. Will be.

  In addition, although the several electric wire holding | maintenance part 14 is supported so that it may arrange in a regular interval with respect to the main-body part 12 here, it is not necessarily required. For example, there may be a portion where the wire holding portions 14 are arranged at a relatively narrow interval and a portion where the wire holding portions 14 are arranged at a relatively wide interval.

  Moreover, the said clamping part 14b has two edge parts which face each other. The distal end side portion 14c of the two end portions is slightly expanded toward the distal end direction, and the proximal end side portion 14d of the two end portions that are abutted is slightly expanded toward the proximal end direction, The portion 14e between them abuts on each other as a narrow portion.

  Further, the side plate portions 16 are fixed by screwing or the like to both side surfaces adjacent to the one side surface 12f where the holding recess 12a is formed in the main body portion 12, respectively. The side plate portion 16 has a role of preventing the electric wire holding portion 14 inserted and held in the holding recess 12a from dropping from the opening of the holding recess 12a.

  In this electric wire holding bar 10, when the end portion of the terminal-attached electric wire 18 is inserted from the distal end side of the electric wire holding portion 14, the outer peripheral portion of the electric wire 18 with terminal is placed on the inner surface of the distal end side portion 14c of both ends of the holding portion 14b. The both ends of the said clamping part 14b are pushed and expanded in sliding contact. And if the electric wire 18 with a terminal exceeds the part 14e while it is the said narrow part, both ends of the clamping part 14b will elastically return and will narrow to an original form. Thereby, the edge part of the electric wire 18 with a terminal comes to be hold | maintained between the both ends of the clamping part 14b in the shape of retaining.

  7 is a schematic front view showing the electric wire end holding set portion 32, FIG. 8 is a schematic front view showing a part of the electric wire end holding set portion 32, and FIG. It is a schematic side view which shows a part.

  The first lifting / lowering drive unit 37b is configured by an actuator such as an air cylinder, and is configured to drive the intermediate plate 37c to move up and down. The pair of second raising / lowering drive units 37d are each configured by an actuator such as an air cylinder, and are configured to individually drive the pair of individual plates 37e up and down. Thereby, the 1st raising / lowering drive part 37b carries out the raising / lowering drive synchronously of a pair of holding part 38, and a pair of 2nd raising / lowering drive part 37d becomes a structure which raises / lowers a pair of holding part 38 separately.

  The pair of gripping portions 38 are supported in a suspended manner on each of the pair of individual plates 37e, and are configured to be able to grip and release the end of the electric wire 18 with a terminal. More specifically, each gripping portion 38 includes a pair of claw portions 38a and a claw portion driving portion 38b that is configured by an actuator such as an air cylinder and moves the pair of claw portions 38a toward and away from each other. . A pair of nail | claw part 38a is branched into two toward the front end side, and it is comprised so that the edge part of the electric wire 18 with a terminal can be hold | gripped in two places spaced apart in the longitudinal direction. Then, by driving the claw portion driving portion 38b, the pair of claw portions 38a are moved closer to each other, whereby the end portion of the terminal-attached electric wire 18 is gripped between the both claw portions 38a, and the pair of claw portions is driven by the claw portion driving portion 38b. By moving the portion 38a away from each other, the gripping of the end portion of the terminal-attached electric wire 18 from between the claw portions 38a is released.

  Further, the set portion moving mechanism 39 reciprocates the wire end gripping set portion 37 between a position corresponding to the pair of wire end holding portions 27 located at the delivery position WP and the bar support portion 50. Here, the set portion moving mechanism 39 includes a pair of pulley bodies 39a, a motor 39b capable of rotating the pulley body 39a on one side in both forward and reverse directions, and an endless annular belt wound around the pair of pulley bodies 39a. And a body 39c. The base plate 37a of the wire end gripping set portion 37 is connected to the middle of the belt body 39c. Then, by rotating the motor 39b in both forward and reverse directions, the wire end gripping set portion 37 reciprocates between the position corresponding to the pair of wire end holding portions 27 located at the delivery position WP and the bar support portion 50. While being driven, it is configured to be able to stop at an arbitrary position on the way. In addition to the above configuration, the set unit moving mechanism 39 can be configured by various actuators such as a linear moving mechanism using a motor and a ball screw mechanism.

  In the electric wire end portion holding set portion 32, the end portion of the terminal-attached electric wire 18 is conveyed and set on the electric wire holding bar 10 as follows.

  That is, by driving the set portion moving mechanism 39, the wire end gripping set portion 37 is moved to an upper position corresponding to the pair of wire end holding portions 27 located at the delivery position WP. Then, in a state where the pair of claws 38a of the pair of grips 38 are separated from each other, the pair of claws 38a is lowered by driving the first elevating drive unit 37b to lower the pair of grips 38a. The ends of the terminal-attached electric wires 18 gripped by the pair of electric wire end holding portions 27 located at the delivery position WP are moved to a position where they can be sandwiched. In this state, the end portions of the terminal-attached electric wires 18 are gripped by the pair of claw portions 38a by moving the pair of claw portions 38a closer to each other by driving the claw portion driving portions 38b. Thereafter, the pair of gripping portions 38 is raised by driving the first lifting and lowering driving portion 37b, and further, the wire end holding set portion 37 is supported by the bar support portion 50 by driving the set portion moving mechanism 39. Move above bar 10.

  Above the wire holding bar 10 supported by the bar support portion 50, first, the end of the terminal-attached electric wire 18 held by one holding portion 38 is set among the electric wire holding portions 14 of the electric wire holding bar 10. The electric wire end gripping set portion 37 is moved by driving the set portion moving mechanism 39 so as to be positioned above the power position. In this state, the end of the terminal-attached electric wire 18 held by the one holding portion 38 by driving the second raising / lowering driving portion 37d or by both the first raising / lowering driving portion 37b and the second raising / lowering driving portion 37d. The one holding part 38 is lowered to a position where the part is held by the electric wire holding part 14 to be set. Then, the gripping by the one gripping part 38 is released by moving the pair of claws 38a of the one gripping part 38 apart by driving the claw part driving part 38b. Thereby, one end part of the electric wire 18 with a terminal is set to the desired electric wire holding part 14. FIG.

  Which wire holding portion 14 in the wire holding bar 10 is to be set with the end portion of the terminal-attached electric wire 18 is determined according to a work command to the control unit 90 as described later. That is, the manufacturing order of the plurality of types of terminal-attached electric wires 18 and the arrangement order of the manufactured electric wires 18 with terminals are set as work instructions, and the control unit 90 performs the gripping based on the setting contents. It is determined to which wire holding portion 14 in the wire holding bar 10 the end portion of the terminal-attached electric wire 18 should be set. And the control unit 90 controls the electric wire edge part holding | maintenance set part 32 so that it may set to the electric wire holding part 14 of the said position. As a result, the end portions of the plurality of types of terminal-attached electric wires 18 are sequentially set on the electric wire holding portions 14 of the electric wire holding bar 10 so that they are arranged in the preset order.

  Further, by inputting that the same type of terminal-attached electric wire 18 is manufactured as a work command, the control unit 90 sequentially places the end of the same type of terminal-attached electric wire 18 on the electric wire holding bar 10 and each electric wire holding portion 14. The wire end holding and setting unit 32 is controlled so as to be set.

  It should be noted that the manufacturing order of the plurality of types of terminal-attached electric wires 18 and the arrangement order of the end portions of the electric wires 18 with terminals in the electric wire holding bar 10 do not necessarily need to match. The production order and the arrangement order of the end portions are appropriately determined according to the production status in the next process, for example.

  Thereafter, the one gripping portion 38 is lifted by driving the second lifting / lowering driving portion 37d or by both driving of the first lifting / lowering driving portion 37b and the second lifting / lowering driving portion 37d. Next, the end portion of the terminal-attached electric wire 18 held by the other holding portion 38 is also set in another desired electric wire holding portion 14 by the same operation as described above. When both ends of the terminal-attached electric wire 18 are set in the electric wire holding portions 14 of the electric wire holding bar 10, the electric wire end gripping set portion 37 is positioned at the delivery position WP by driving the setting portion moving mechanism 39. It moves to the upper position corresponding to a pair of electric wire edge part holding | maintenance part 27, and repeats the said operation | movement. Thereby, the both ends of the electric wire 18 with a terminal crimped by the cutting pressure mechanism 22 are sequentially set to the electric wire holding portions 14 of the electric wire holding bar 10 in the order of manufacture.

Here, the bar supply mechanism 40 includes two bar support portions 50. In FIG. 3 and FIG. 4, one bar support portion 50 is located at the wire receiving position RP, and the other bar support portion 50 is 2 in number. The state located in one of the two extraction positions TP is shown.

  The two bar support portions 50 are configured such that the electric wire holding bar 10 can be set respectively.

  The movable support mechanism 55 reciprocates the two bar support portions 50 between the wire receiving position RP from the wire end holding set portion 32 and the take-out position TP of the wire holding bar 10. At this time, the two bar support portions 50 are reciprocated with a constant interval. The take-out position TP with respect to the two bar support portions 50 is different along the direction orthogonal to the extending direction of the electric wire holding bar 10 with the electric wire receiving position RP interposed therebetween. When one wire holding bar 10 is disposed at the wire receiving position RP, the other wire holding bar 10 is disposed at one take-out position TP, and the other wire holding bar 10 is disposed at the wire receiving position RP. When installed, one electric wire holding bar 10 is arranged at the other extraction position TP.

  Thereby, during the operation of holding the electric wire 18 with terminal on the electric wire holding bar 10 located at the electric wire receiving position RP, the electric wire holding bar 10 holding the electric wire 18 with terminal located at the take-out position TP is taken out, The work of replacing the empty electric wire holding bar 10 can be performed smoothly. However, only one or three or more bar support portions 50 may be provided.

  The drive mechanism 70 reciprocates the two bar support portions 50 by reciprocating the movable support mechanism 55.

  More specifically, the two bar support portions 50 are movable in a state where they are arranged in parallel at intervals (a state in which the extending direction of the electric wire holding bar 10 supported by the two bar support portions 50 is parallel). It is supported by the support mechanism 55.

  The bar support portion 50 includes a long bar support base portion 51, a bar receiving portion 52 projecting upward from one end portion of the bar support base portion 51, and a pair of side plate portions 53.

  The thickness dimension of the bar support base 51 is set to be the same as the thickness dimension of the electric wire holding bar 10. The pair of side plate portions 53 are attached so as to extend upward from both side surfaces of the bar support base portion 51. And the space which can accommodate the electric wire holding bar 10 is formed between the upper surface of the bar support base 51 and the inward surfaces of the pair of side plate portions 53.

  Further, one end of the electric wire holding bar 10 is received by the bar receiving portion 52 in a state where the electric wire holding bar 10 is accommodated between the bar support base portion 51 and the pair of side plate portions 53. Here, the bar receiving portion 52 is provided with a positioning pin 52p that can be inserted into the guide hole 12g at one end of the wire holding bar 10. The positioning pin 52p is formed in a tapered shape. With the positioning pin 52p inserted into the guide hole 12g, the electric wire holding bar 10 is supported by the bar support portion 50, so that the electric wire holding bar 10 can be more reliably supported at a fixed position. The positioning pin 52p is biased in the protruding direction by a biasing member such as a coil spring. Thereby, the electric wire holding bar 10 can be supported without rattling.

  The distance between the other end of the bar support base 51 and the bar receiver 52 is set to be shorter than the length of the wire holding bar 10. For this reason, in a state where the electric wire holding bar 10 is supported by the bar support portion 50, the other end portion of the electric wire holding bar 10 protrudes outward from the other end portion of the bar support portion 50.

  The movable support mechanism 55 includes a base portion 56 and a movable support portion 60.

  The base part 56 is a part fixedly installed at a fixed position on the floor surface. The base portion 56 includes a pair of guide rails 57 and a connecting base portion 58 that connects the pair of guide rails 57.

  The pair of guide rails 57 is a rod-shaped member made of metal or the like, more specifically, a square bar-shaped member. The pair of guide rails 57 are set to have the same length, but are not necessarily required. Guide grooves 57g are formed on the upper and lower surfaces of the guide rail 57 along the extending direction thereof (see FIGS. 3 and 10). Here, the guide groove 57 g formed on the upper surface of the guide rail 57 is formed at a position outside the guide groove 57 g formed on the lower surface of the guide rail 57.

  The pair of guide rails 57 are arranged in parallel with a gap therebetween. Here, both ends of the pair of connection base portions 58 are connected to both ends of the pair of guide rails 57 by screws or the like, so that the pair of guide rails 57 and the pair of connection base portions 58 form a rectangular frame shape. Is associated with.

  The pair of guide rails 57 and the pair of connection base portions 58 are supported by the legs 59 at positions away from the floor surface. In a state in which the pair of guide rails 57 and the pair of connection base portions 58 are placed on the floor surface via the leg portions 59, the pair of guide rails 57 are below the wire receiving position RP and the extraction position TP and At a position floating from the floor surface, the wire holding bar 10 is disposed in a horizontal posture orthogonal to the extending direction.

  The movable support part 60 includes a rectangular frame part 61 and a column part 69.

  The rectangular frame portion 61 is configured such that a pair of vertical frame portions 62 and a pair of horizontal frame portions 63 are combined so as to form a rectangular frame shape. The length dimension of the pair of vertical frame portions 62 is set shorter than the length dimension of the pair of guide rails 57. In addition, the length dimension of the pair of horizontal frame parts 63 is set to be the same as or close to the length dimension of the connection base part 58. Each of the pair of vertical frame portions 62 can be disposed along the pair of guide rails 57.

  Supporting column portions 69 are erected at two locations in the intermediate portion in the extending direction of each of the pair of vertical frame portions 62. One bar support portion 50 is supported in a horizontal posture on the upper end portion of the column portion 69 erected at one place in the extending direction intermediate portion of each of the pair of vertical frame portions 62. Further, the other bar support portion 50 is supported in a horizontal posture on the upper end portion of the support column portion 69 erected at the other one portion in the extending direction intermediate portion of each of the pair of vertical frame portions 62. Thereby, the movable support part 60 supports the bar support part 50 so that a movement is possible.

  Here, the bar supply mechanism 40 further includes a guide portion 42. The guide part 42 was supported by the bar support part 50 during the movement of the bar support part 50 so that the electric wire holding bar 10 supported by the bar support part 50 is horizontal in a state where it is located at the electric wire receiving position RP. It is provided so that the height of the other side end portion in the extending direction of the electric wire holding bar 10 can be regulated. That is, the guide portion 42 supports the other end portion of the electric wire holding bar 10 which is a free end, thereby restricting the other end portion of the electric wire holding bar 10 to a predetermined height at the electric wire receiving position RP. This is the part that makes the wire holding bar 10 horizontal.

  Specifically, the guide part 42 is formed in an isosceles trapezoidal plate shape here. The guide part 42 is provided so that it may be located under the other end part of the electric wire holding bar 10 in the electric wire receiving position RP. Moreover, the guide part 42 is provided so that the thickness direction of a board may correspond with the extending direction of an electric wire holding bar. The upper surface of the guide part 42 has a support surface 43a and a guide surface 43b extending from the support part to both sides. The support surface 43a is provided so as to be parallel to the horizontal plane, and the guide surface 43b extends from the support surface 43a toward both ends thereof so that the height in the vertical direction gradually decreases.

  At the take-out position TP, the other end of the electric wire holding bar 10 is a free end, and the electric wire holding bar 10 is supported in a horizontal state or in a state where the other end is slightly lowered. And when the electric wire holding bar 10 is supported in a state where the other side end portion is slightly lowered, the bottom surface of the electric wire holding bar 10 comes into contact with the guide surface 43b of the guide portion 42 when moving from the take-out position TP to the electric wire receiving position RP. It is guided to the height position of the support surface 43a. Thereby, the electric wire holding bar 10 is supported in a horizontal state by the upper surface of the bar support portion 50 and the support surface 43a of the guide portion 42 at the electric wire receiving position RP. For this reason, the electric wire holding bar 10 is more reliably maintained horizontal during the setting of the electric wires.

  Here, the bar supply mechanism 40 includes a bar positioning portion 44 provided at the wire receiving position RP. The bar positioning unit 44 includes a pressing unit 45 and a receiving unit 46.

  The pressing portion 45 is a portion that can directly or indirectly press the other end portion of the wire holding bar 10 at the wire receiving position RP toward one end portion.

  Specifically, the push part 45 includes a bar end push part 45a and a horizontal drive part 45b. The bar end pressing portion 45a is formed in a tapered pin shape, and is inserted into the guide hole 12g at the other end of the wire holding bar 10 with the other end of the wire holding bar 10 at one end. It is formed in a shape that can be pushed toward the part.

  The horizontal drive part 45b is comprised by actuators, such as an air cylinder, and is comprised so that a bar end part press part 45a can be reciprocated in a horizontal direction. Here, the horizontal drive part 45 b is configured to be able to drive the bar end pressing part 45 a along the extending direction of the electric wire holding bar 10. In addition, the member which presses the other end part of an electric wire holding bar may also protrude in the other end part of a bar support part, and a pressing part may push the other end part of an electric wire holding bar through the said member.

  Moreover, the receiving part 46 is comprised so that the other end part of the electric wire holding bar 10 pushed by the pushing part 45 can be received directly or indirectly.

  Specifically, the receiving unit 46 includes a bar end receiving unit 46a and a horizontal driving unit 46b. The bar end receiving portion 46a is configured such that a V-shaped receiving groove 46g is formed at the tip of the rectangular plate-like portion (see FIG. 3). Here, a receiving pin 50 </ b> P protrudes from a lower portion of one end portion of the bar support portion 50. And the movement to the one end part side of the bar | burr support part 50 is controlled because the said receiving pin 50P fits into the receiving groove 46g of the bar | burr edge part receiving part 46a. Since the electric wire holding bar 10 is restricted from moving toward the other end by the bar receiving portion 52 of the bar supporting portion 50, the electric wire holding bar 10 is connected to the end of the bar via the bar supporting portion 50 and the receiving pin 50P. It is received by the receiving part 46a. A receiving part may receive the one end part of the electric wire holding bar 10 directly, and may restrict | limit the movement to the one end part side.

  The horizontal drive part 46b is comprised by actuators, such as an air cylinder, and is comprised so that a bar end part receiving part 46a can be reciprocated in a horizontal direction. Here, the horizontal drive part 46 b is configured to be able to drive the bar end receiving part 46 a along the extending direction of the wire holding bar 10.

  In the state before the empty wire holding bar 10 moves to the wire receiving position RP, the bar end pressing portion 45a and the bar end receiving portion 46a are driven by the horizontal driving portions 45b and 46b so that the wire holding bar 10 And it is located in the position retracted | saved outward from the movement locus | trajectory of the bar support part 50. FIG. In this state, when the empty electric wire holding bar 10 moves to the electric wire receiving position RP, the bar end pressing portion 45a and the bar end receiving portion 46a approach the electric wire holding bar 10 by driving the horizontal driving portions 45b and 46b. Move in the direction. Accordingly, the bar end pressing portion 45a presses the electric wire holding bar 10 and the bar support portion 50 toward one end thereof. Then, the receiving pin 50P at one end of the bar support portion 50 is received by the bar end receiving portion 46a. Thereby, the electric wire holding bar 10 is supported at a fixed position in the extending direction, and it is possible to suppress the occurrence of positional displacement during the operation of holding the electric wire.

  When the predetermined number of terminal-attached electric wires are set in the electric wire holding bar 10, the horizontal end portions 45b and 46b cause the bar end pressing portion 45a and the bar end receiving portion 46a to move away from the electric wire holding bar 10. Move away. Thereby, the electric wire holding bar 10 in which the setting of the electric wires is completed can move toward the take-out position TP, and the empty electric wire holding bar 10 can move toward the electric wire receiving position RP. Thereafter, the above operation is repeated as the bar support portion 50 moves.

  Note that the bar positioning portion 44 may be omitted.

  A configuration for supporting the movable support 60 so as to be movable with respect to the pair of guide rails 57 will be described. FIG. 10 is an explanatory diagram showing the positional relationship of the upper roller 64, the lower roller 65, and the side rollers 66 and 67 with respect to the pair of guide rails 57 when viewed along the extending direction of the guide rails 57.

  As shown in FIG. 2 to FIG. 4 and FIG. 10, the movable support portion 60 includes a pair of an upper roller 64, a lower roller 65, and side rollers 66 and 67 that are rotatably supported by the movable support portion 60. The guide rail 57 is supported so as to be movable.

  That is, the upper roller 64 is rotatably supported around the vertical axis via the shaft portion 64a at the outer positions of both ends of the pair of vertical frame portions 62. The upper roller 64 is supported so as to be able to run on the upward surface of the guide rail 57. Here, the upper roller 64 is supported so as to be able to travel in the guide groove 57 g on the upper side of the guide rail 57. The width dimension of the guide groove 57g is set larger than the width dimension of the upper roller 64. It is not essential for the upper roller 64 to travel in the guide groove 57g.

  In addition, the lower roller 65 is rotatably supported via a shaft portion 65a and a bracket 65b at an outer position at an intermediate portion in the extending direction of each of the pair of vertical frame portions 62. More specifically, a plate-like bracket 65b is attached so as to extend downward from the lower surface of the vertical frame portion 62, and the lower roller 65 is provided around the vertical axis via the shaft portion 65a at the lower end portion of the bracket 65b. It is rotatably supported. The lower roller 65 is supported so as to be able to run on the downward surface of the guide rail 57. Here, the lower roller 65 is supported so as to be able to travel in the guide groove 57g on the lower side of the guide rail 57. The width dimension of the guide groove 57g is set larger than the width dimension of the lower roller 65. It is not essential for the lower roller 65 to travel in the guide groove 57g.

  Further, the side rollers 66 and 67 are rotatably supported via shafts 66a and 67a and brackets 66b and 67b at inner positions of both ends of the pair of vertical frame portions 62, respectively. The side rollers 66 and 67 are supported so as to be able to run on one and other side surfaces of the guide rail 57. Here, the side roller 66 is rotatably supported by one of the pair of vertical frame portions 62 via a shaft portion 66a and a bracket 66b. More specifically, the bracket 66b is formed of a U-shaped metal member or the like, one end of which is fixed to the lower surface of one vertical frame portion 62, and the other end is connected to the side through the shaft portion 66a. A side roller 66 is supported so as to be rotatable about a horizontal axis. The side roller 66 is disposed at a position where it can travel on one side surface of the one vertical frame portion 62. Further, the side roller 67 is rotatably supported on the other of the pair of vertical frame portions 62 via a shaft portion 67a and a bracket 67b. More specifically, the bracket 67b is formed of a U-shaped metal member or the like, one end of which is fixed to the lower surface of the other vertical frame portion 62, and the other end is connected to the side through the shaft portion 67a. A side roller 67 is supported so as to be rotatable around a horizontal axis. The side roller 66 is disposed at a position where it can travel on the other side surface of the other vertical frame portion 62.

  Here, one side surface (inwardly facing surface) of one vertical frame portion 62 on which the side roller 66 can travel and the other side surface (inwardly facing surface) of the other vertical frame portion 62 on which the side roller 67 can travel. ) Is a positional relationship facing in opposite directions. For this reason, the side rollers 66 and 67 are in a state where they can run against the side surfaces of the vertical frame portion 62 in opposite directions. Therefore, the position of the movable support 60 in the width direction can be regulated by these side rollers 66 and 67.

  In addition, a pair of side roller may be provided so that it can drive | work on the outward side surface of a pair of vertical frame part. In addition, here, the pair of side rollers 66 and 67 are provided separately for the pair of guide rails 57, but both side surfaces (one side surface) of one guide rail common to the pair of side rollers. And the other side surface) may be arranged so as to be able to travel. In other words, the pair of side rollers may be provided so as to be able to run on one side surface and the other side surface facing in opposite directions regardless of whether the guide rail is one or plural. Further, the side rollers 66 and 67 may run in the guide groove formed on the side surface of the vertical frame portion.

  Further, a gap S <b> 1 is provided between at least one of the upward surfaces of the pair of guide rails 57 and the upper roller 64 and between the downward surface of the pair of guide rails 57 and the lower roller 65. Here, basically, the upper roller 64 travels on the bottom surface of the guide groove 57g, which is the upward surface of the guide rail 57. Therefore, in the normal state, the bottom surface of the guide groove 57g, which is the downward surface of the guide rail 57, and the bottom surface of the guide groove 57g. A gap S <b> 1 is provided between the roller 65. A gap S <b> 2 is provided between one and the other side surfaces of the pair of guide rails 57 and at least one of the pair of side rollers 66.

  For this reason, the movable support portion 60 basically moves along the extending direction of the guide rail 57 when each upper roller 64 travels on the bottom surface of the guide groove 57g which is the upward surface of the guide rail 57. It is supported movably. When the movable support portion 60 is inclined, any one of the upper rollers 64 floats from the bottom surface of the guide groove 57g that is the upward surface of the guide rail 57, and any one of the lower rollers 65 is the downward surface of the guide rail 57. It runs on the bottom surface of the guide groove 57g. Further, when the movable support portion 60 tries to shake in the width direction, any one of the side rollers 66 and 67 travels on any side surface of the guide rail 57. As a result, the movable support portion 60 is allowed to move in a vertical direction, a horizontal direction, or a combined tilt direction with respect to the guide rail 57 within a range determined by the gaps S1 and S2, while extending the guide rail 57. It is supported so as to be movable along the present direction.

  The drive mechanism 70 reciprocates the two bar support portions 50 by reciprocating the movable support mechanism 55. Here, as described above, the following configuration is adopted so that the movable support 60 can be moved even when the movable support 60 is displaced up and down, left and right.

  11 is a schematic exploded perspective view showing a connection configuration between the movable support portion 60 and the drive mechanism 70, FIG. 12 is a schematic perspective view showing a connection configuration between the movable support portion 60 and the drive mechanism 70, and FIG. It is a schematic sectional drawing which shows the protrusion 68P for a movement accommodated in the movable part 72 for a movement.

  That is, the movable support portion 60 is provided with a moving protrusion 68P. More specifically, a base 68 protrudes outwardly from the vertical frame 62 on the side close to the cutting pressure mechanism 22 of the pair of vertical frames 62, and the movement protrusions are formed on the base 68. A portion 68P is projected. Here, the moving projection 68P is formed in a columnar shape, but may have a rectangular parallelepiped shape or the like.

  The drive mechanism 70 includes a drive main body 71 and a movable part 72 for movement.

  The drive main body 71 is a linear actuator, a linear actuator composed of a linear movement mechanism that combines a ball screw mechanism and a motor, an air cylinder, a hydraulic cylinder, or the like, and the moving movable portion 72 is connected to the bar support portion 50. Reciprocate along the moving direction. The drive main body 71 itself is supported at a fixed position. Here, it is fixed to the casing of the cutting pressure mechanism 22, and the moving movable portion 72 protrudes from the cutting pressure mechanism 22 toward the electric wire discharging device 30, and at a position away from the floor surface upward of the guide rail 57. It is supported so that it can reciprocate linearly along the extending direction.

  The moving movable portion 72 is formed with a housing recess 73 that opens downward and in a direction orthogonal to the extending direction of the guide rail 57. Two surfaces facing each other with a gap in the housing recess 73 are a pair of moving contact surfaces 74 facing the one side or the other side in the extending direction of the guide rail 57.

  When viewed along the direction in which the guide rail 57 extends, the moving projection 68 </ b> P is disposed at a position that fits into the housing recess 73 of the moving movable portion 72 from below. In this state, one of the pair of moving contact surfaces 74 contacts the moving projection 68P from one side in the extending direction of the guide rail 57, and the other of the pair of moving contact surfaces 74 is the guide rail 57. Can be brought into contact with the moving projection 68P from the other side in the extending direction. For this reason, when the moving movable portion 72 is moved to one side along the extending direction of the guide rail 57, the one moving contact surface 74 causes the moving protrusion 68P to move to the one side in the extending direction of the guide rail 57. To move the movable support 60 to one side of the guide rail 57 in the extending direction. When the moving movable portion 72 is moved to the other side along the extending direction of the guide rail 57, the other moving contact surface 74 pushes the moving protrusion 68P to the other side in the extending direction of the guide rail 57, Accordingly, the movable support portion 60 is moved to the other side in the extending direction of the guide rail 57. Note that a gap may or may not exist between the pair of moving contact surfaces 74 and the moving projection 68P.

  As described above, the upper end of the moving projection 68P is separated from the ceiling surface of the receiving recess 73 in a state where the moving projection 68P is fitted in the receiving recess 73, and the moving movable portion 72 is moved. The lower surface of is spaced from the base 68. For this reason, the moving projection 68 </ b> P is housed in the housing recess 73 so as to be movable in the vertical direction with respect to the guide rail 57.

  Further, the moving projection 68P is movable between a pair of moving contact surfaces 74 along a horizontal direction orthogonal to the extending direction of the guide rail 57. Therefore, the moving projection 68 </ b> P is housed in the housing recess 73 even in a state where it can move in the left-right direction with respect to the guide rail 57.

  As described above, the moving projection 68 </ b> P is accommodated in the accommodating recess 73 between the pair of moving contact surfaces 74 so as to be movable in the vertical direction and the horizontal direction with respect to the guide rail 57. For this reason, even if the movable support portion 60 moves in the vertical direction and the left-right direction with respect to the guide rail 57, the drive mechanism 70 can move the movable support portion 60 along the extending direction of the guide rail 57. it can.

  The operations of the cutting pressure mechanism 22 and the wire discharging device 30 are controlled by a control unit 90 configured by a general microcomputer including a CPU, a ROM, a RAM, and the like. An input unit 92 composed of various keys, a touch panel, and the like is connected to the control unit 90, and work instructions are input through the input unit 92.

  The control unit 90 receives a command regarding the manufacturing order of the plurality of types of the electric wires 18 with terminals in the cutting pressure mechanism 22 through the input unit 92, selects a plurality of types of wires and a plurality of types of terminals according to the commands, and responds to the commands. It controls so that the electric wire 18 with a terminal was manufactured. The control unit 90 is configured to be able to accept a command regarding the arrangement order of the end portions of the terminal-attached electric wires 18 manufactured through the input unit 92, and the end portions of the electric wires 18 with terminals are held in accordance with the instructions. It is comprised so that it may set to each electric wire holding part 14 of the bar 10.

  Further, the control unit 90 moves the electric wire holding bar 10 positioned at the electric wire receiving position RP to the one extraction position TP when the setting of the preset electric wires 18 with terminals on the electric wire holding bar 10 positioned at the electric wire receiving position RP is completed. And the drive mechanism 70 of the wire discharge device 30 is controlled so that the wire holding bar 10 located at the other extraction position TP is moved to the wire receiving position RP. In accordance with this, the bar positioning unit 44 is controlled at the timing when the wire holding bar 10 moves from the wire receiving position RP toward the take-out position TP, or at the timing when it reaches the wire receiving position RP from the take-out position TP, The wire holding bar 10 is positioned at the wire receiving position RP.

<Operation>
The overall operation of the cutting pressure setting device 1 and the wire discharging device 30 configured as described above will be described.

  First, the wire 18 with a terminal which cut | disconnected the predetermined | prescribed electric wire in predetermined length in the cutting pressure mechanism 22, and crimped | bonded the predetermined | prescribed terminal is manufactured sequentially (refer FIG. 1). Then, both ends of the manufactured electric wire 18 with a terminal are conveyed to the delivery position WP by the pair of electric wire end holding portions 27 of the electric wire end reciprocating drive unit 28. Whether the same kind of terminal-attached electric wires 18 are manufactured continuously or whether a plurality of types of electric wires 18 with terminals are manufactured in a predetermined order is a command given to the control unit 90 through the input unit 92 in advance. Is made according to.

  Both ends of the terminal-attached electric wire 18 supported by the pair of electric wire end holding portions 27 positioned at the delivery position WP are respectively held by the pair of holding portions 38 of the electric wire end holding set portion 32, and the bar support portion 50. It moves to the upper part of the electric wire holding bar 10 set to. And in the state which moved to the appropriate position along the longitudinal direction of the electric wire holding bar 10, a pair of holding | grip part 38 moves down separately, and each edge part of the electric wire 18 with a terminal is in the electric wire holding bar 10. It is set in the electric wire holding part 14 of a desired position (refer FIG.1 and FIG.7).

  By repeating the above processing on the terminal-attached electric wires 18 sequentially manufactured in the cutting pressure mechanism 22, both end portions of the plurality of terminal-attached electric wires 18 are set in each electric wire holding portion 14 of the electric wire holding bar 10. Thereby, the thing by which the both ends of the some electric wire 18 with a terminal were set to each electric wire holding part 14 of the electric wire holding bar 10 is obtained.

  When the setting of the terminal-attached electric wire 18 to the electric wire holding bar 10 supported by the one bar support portion 50 is completed, the control unit 90 gives a command to the drive mechanism 70. In response to this command, the drive mechanism 70 moves the empty electric wire holding bar 10 supported by the other bar support portion 50 to the electric wire receiving position RP, and at the same time the set electric wires supported by the one bar support portion 50 are set. The holding bar 10 is moved to one extraction position TP. And while the electric wire 18 with a terminal is set to the electric wire holding | maintenance bar 10 supported by the other bar | burr support part 50, an operator has set the electric wire holding | maintenance bar 10 already supported by the one bar | burr support part 50. And the empty wire holding bar 10 is attached to one of the bar support portions 50.

  As described above, when the operator repeats the work of replacing the set electric wire holding bar 10 with an empty one at the take-out position TP, a plurality of sets of electric wire holding bars 10 in which the ends of the terminal-attached electric wires 18 are set are set. Can be obtained.

<Effects>
In the electric wire discharging device 30 configured as described above, the bar support portion 50 is vertically moved with respect to at least one of the guide rails 57 while being supported so as to be reciprocally movable between the electric wire receiving position RP and the extracting position TP. It can move in the direction and the left-right direction. Therefore, for example, at the wire receiving position RP, the wire holding bar 10 can be accurately positioned at an accurate position suitable for setting the terminal-attached wire 18 from the wire end holding set portion 32. More specifically, as shown in FIG. 14, in the electric wire receiving position RP, when the one end portion of the electric wire holding bar 10 is pushed and positioned at a predetermined position by the pressing portion 45 of the bar positioning portion 44, the movable support is provided. Even when it is necessary to horizontally move or tilt the portion 60 in the same direction (see the movable support portion 60 indicated by a two-dot chain line), the wire holding bar 10 and the movable support portion 60 follow the movement of pressing the wire holding bar 10. Can be moved. Thereby, the electric wire holding bar can be positioned more accurately at the electric wire receiving position. In other words, it can be said that there is no need to accurately assemble the support structure of the movable support portion 60 so that the wire holding bar 10 moves to the wire receiving position RP with high accuracy. For this reason, the structure which supports the electric wire holding bar 10 so that a reciprocation is possible between the electric wire receiving position RP and the extraction position TP is easily assembled.

  Further, the configuration using the upper roller 64, the lower roller 65, and the side roller 66 as described above has an advantage that the cost is lower than the configuration using a linear guide or the like.

  In addition, since the upper roller 64 and the lower roller 65 are provided on each of the pair of guide rails 57, the movable support portion 60 is firmly and movably supported by each of the pair of guide rails 57 in the vertical direction. Can do. In addition, one of the pair of side rollers 66 is provided so as to be able to run on one side surface of the pair of guide rails 57, and the other side roller 67 is able to run on the other side surface of the pair of guide rails 57. Since it is provided, the left and right direction can be guided with a simple configuration.

  Further, a moving projection 68P is provided on the movable support portion 60, and a pair of moving projections that can come into contact with the moving projection 72P from both sides of the guide rail 57 in the extending direction. An accommodation recess 73 capable of accommodating the movement projection 68P is formed between the pair of movement contact surfaces 74 in a state that includes the contact surface 74 and is movable in the vertical and horizontal directions with respect to the guide rail 57. Therefore, as described above, even when the movable support portion 60 is displaced in the vertical direction or the left and right supplementary lectures, the movable support portion 60 is moved while maintaining the connection state between the drive mechanism 70 and the movable support portion 60. Can do.

{Modifications}
The configuration of the drive mechanism 70 is not limited to the above example. For example, a configuration in which the upper roller 64 is rotationally driven may be used as the drive mechanism.

  Moreover, in the said embodiment, although it becomes the structure by which the protrusion 68P for movement fits from the downward direction of the accommodation recessed part 73, the accommodation recessed part is opened to the side or upper direction, and the protrusion for movement is an accommodation recessed part. May be fitted from the side or from above.

  Moreover, in the said embodiment, although the protrusion 68P for a movement was provided in the movable support part 60 and the accommodating recessed part 73 was formed in the movable part 72 for a movement, on the contrary, in the movement support part, it demonstrated. An accommodation recess may be formed, and a moving protrusion may be provided on the moving movable part.

  Moreover, in the said embodiment, it demonstrates by the example which reciprocates the movable support part 60 and the electric wire holding bar 10 in the direction orthogonal to the direction where the electric wire end holding | maintenance set part 32 moves the edge part of the electric wire 18 with a terminal. However, a configuration in which the movable support portion and the wire holding bar are reciprocated in the same direction as the direction in which the wire end holding set portion moves the end portion of the terminal-attached electric wire may be used.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
