  The terminal molding die apparatus as described above may be incorporated into a wire end processing facility that performs stripping processing or the like on the end of the wire to crimp the terminal. Here, different types of terminals may be crimped to the electric wires. In order to cope with this, as shown in FIG. 34, a configuration is conceivable in which a reel 212 and a terminal molding die device 214 having a pair of dies are mounted on a replacement rack 210 and these are exchanged together. .

  As an example of the layout in this case, for example, as shown in FIG. 35, the reel 212 and the terminal molding die device 214 having a pair of molds are positioned along the conveying line L that conveys the end of the electric wire W. A configuration is possible in which the replacement rack 210 is disposed so that the replacement rack 210 is moved forward and backward with respect to the transport line L in this posture. Note that the terminal molding die device 214 is disposed below the press device 216 in a state where the replacement rack 210 has moved forward into the transfer line L. In addition, with the replacement rack 210 retracted from the transfer line L, the replacement rack 210 itself can be replaced or the terminal molding die device 214 can be replaced with the replacement rack 210.

  However, in this example, since the reel 212 is disposed along the transport line L, a useless space m in which the end of the electric wire W cannot be processed in the transport line L is generated.

  Also, for example, as shown in FIG. 36, the reel 212 and the terminal molding die device 214 having a pair of dies are arranged in an attitude inclined with respect to the conveying line L that conveys the end of the electric wire W. Thus, a configuration is possible in which the replacement rack 210 is disposed and the replacement rack 210 is moved forward and backward with respect to the transport line L in this posture.

  However, in this case, it is necessary to employ a mechanism for moving the replacement rack 210 obliquely with respect to the transport line L, and there is a problem that such a moving mechanism is difficult to design and manufacture.

  Also, for example, as shown in FIG. 37 and FIG. 38, the reel 222 and the terminal molding die device 224 are disposed on the replacement rack 220 in an orthogonal posture, and as shown in FIG. The replacement rack 220 is disposed so that the end of the electric wire W is orthogonal to the conveyance line L that conveys the terminal W and the terminal molding device 224 is disposed along the conveyance line L. A configuration in which the replacement rack 220 is moved forward and backward with respect to the transport line L in the posture is conceivable.

  However, even in this case, eventually, when the replacement rack 220 is moved forward and backward with respect to the transport line L, a space m1 through which the terminal molding die device 224 orthogonal to the reel 222 passes is required, and the installation area increases. To do.

<1. Overall configuration of wire processing device>
First, the whole structure of the electric wire processing apparatus to which the exchange apparatus of a terminal molding die apparatus is applied is demonstrated. FIG. 1 is a schematic plan view showing a schematic configuration of the electric wire processing apparatus 10. The electric wire processing apparatus 10 includes a cutting unit 112, a peeling unit 114, an electric wire transport unit 14, and a terminal crimping unit 20.

  The cutting unit 112 is configured to be able to cut a long electric wire W wound around a winding reel or the like into a predetermined length. For example, a pair of V-shaped blades are used to peel the electric wire W. Moreover, the peeling unit 114 is configured to be able to peel the covering portion at the end of the electric wire W. The covering portion of the electric wire W is also peeled off using, for example, a pair of V-shaped blades.

  The terminal crimping unit 20 is configured so that a terminal can be crimped to the end of the electric wire W from which the covering portion of the end is peeled off.

  The electric wire transport unit 14 includes a plurality of grip portions 15 that can grip and release the end portions of the electric wires W. The plurality of gripping portions 15 are disposed so as to be able to pass through the front of the cutting unit 112, the rubber plug insertion unit 113, the peeling unit 114, and the terminal crimping unit 20 at predetermined intervals by driving a conveyor or the like. In the state where both ends of the electric wire W processed in 112 are gripped, the rubber plug insertion unit 113 and the peeling unit 114 are sequentially moved toward the terminal crimping unit 20. As a result, the electric wire W cut into a predetermined length is bent into a U-shape and the terminal crimping from the cutting unit 112 in a state where the ends are directed to the rubber plug insertion unit 113, the peeling unit 114, and the terminal crimping unit 20 side. It is conveyed toward the unit 20. Moreover, a rubber plug is inserted into the end of the electric wire W by the rubber plug insertion unit 113 as necessary. The rubber plug insertion unit 113 may be omitted.

  This electric wire processing apparatus 10 is an apparatus that continuously performs a process of cutting a long electric wire W into a predetermined length, a process of peeling off a covering portion at an end thereof, and a process of crimping a terminal to the end of the electric wire W. It is. An exchange device 30 for the terminal molding die device 32 is incorporated in the terminal crimping unit 20.

<2. Overall configuration of terminal crimping unit>
The overall configuration of the terminal crimping unit 20 will be described. The terminal crimping unit 20 is a unit that is incorporated in the wire transport unit 14 and crimps a terminal to the end of the electric wire W transported by the wire transport unit 14, and includes a terminal crimping table 22 and a press mechanism 28 for crimping, And an exchange device 30 for exchanging the terminal molding device 32 disposed between them.

  The terminal crimping table 22 is a plate-like member, and is supported in a horizontal posture along a conveyance line L of the electric wire W by the electric wire conveyance unit 14 by a stand or the like (not shown). The terminal crimping table 22 is formed with a set recess 23 that is recessed toward the electric wire conveyance unit 14 from the side opposite to the electric wire conveyance unit 14. A support base 46 (details will be described later) is disposed in the set recess 23 so as to be able to advance and retract. In a state where the support base 46 has entered the set recess 23, the terminal molding device 32 rotates with respect to the support base 46, so that the terminal molding device 32 moves to the transport line L by the wire transport unit 14. Arranged along.

  In addition, since the electric wire conveyance unit 14 moves the some holding | grip part 15 intermittently, the cutting | disconnection unit 112, the rubber plug insertion unit 113, the peeling unit 114, and the terminal crimping unit 20 are in the stop period of each holding part 15. Perform each action. When the terminal crimping operation time in the terminal crimping unit 20 is longer than the operation time in the cutting unit 112, the rubber plug insertion unit 113, and the peeling unit 114, the processing times may be synchronized as follows.

  That is, as shown in FIG. 2, the wire relay unit 200 is provided between the wire transfer unit 14 and each terminal crimping unit 20. In addition, in FIG. 2 etc., although demonstrated in relation to the one terminal crimping unit 20, the other terminal crimping unit 20 can be similarly provided with the electric wire conveyance unit 200.

  The electric wire relay unit 200 receives the end of the electric wire 13 from the grip portion 15 at a predetermined position, then moves the end of the electric wire 13 toward the terminal crimping unit 20, and the terminal is connected to the end of the electric wire 13. After the crimping operation is performed, the electric wire is delivered to the grip portion 15 at a position downstream of the end of the electric wire 13 in the transport direction from the position where the electric wire 13 is received.

  More specifically, the electric wire relay unit 200 includes an XY moving mechanism unit 204 including a gripping unit 202 that grips the electric wire, a moving mechanism unit in the transport direction, and a moving mechanism unit in a direction orthogonal thereto. Here, the wire relay unit 200 further includes an elevating / lowering mechanism 203 that moves the gripper 202 in the elevating direction. Each moving mechanism is configured by an air cylinder, a linear motor, or the like. The gripper 202 is configured by an air cylinder or an electromagnetic chuck.

  A plurality of gripping portions 202 are transported along the transport line, and at the timing when any gripping portion 202 stops immediately upstream of the terminal crimping unit 20, the gripping portion 202 is at a receiving position facing it. Arranged. In this state, the end of the electric wire 13 is received from the grip portion 202 and the grip by the grip portion 202 is released.

  Thereafter, as shown in FIG. 3, the gripping part 202 is lifted by the lifting / lowering moving mechanism part 203 to avoid interference between the electric wire 13 and the transport unit 14, and the gripping part 202 is crimped to the terminal by driving the XY moving mechanism part 202. The unit 20 is moved toward the terminal crimping position.

  After crimping the terminals, as shown in FIG. 4, the gripping portion 202 is moved toward the return position downstream of the delivery position by driving the XY moving mechanism portion 202, and is gripped by the lifting / lowering moving mechanism portion 203. The part 202 is lowered. Then, the end portion of the electric wire 13 is delivered to the grip portion 202 at that position, and the grip by the grip portion 202 is released.

  In the above example, the movement of the end of the electric wire 13 and the terminal crimping operation can be performed using two stop times of the grip portion 202 and two movement times. For this reason, the stop time of the holding part 202 can be used for one or more times for the terminal crimping operation. Thereby, even if each processing time performed along a conveyance line differs, each processing time can be synchronized and efficient processing can be performed.

  The press-bonding press mechanism portion 28 is a mechanism that imparts a reciprocating linear motion to the terminal molding die device 32, and includes an air cylinder, a hydraulic cylinder, a combination mechanism of a motor and a cam, and the like. This crimping press mechanism portion 28 is disposed above the terminal crimping table 22 and at one side position of the set recess 23. Then, in the state where the terminal molding die device 32 is arranged along the conveyance line L by the electric wire conveyance unit 14 as described above, the press bonding press mechanism portion 28 is arranged above the terminal molding die device 32. The Thereby, the press mechanism part 28 for crimping | compression-bonding can provide the press force for crimping | bonding a terminal with respect to the lower terminal molding die apparatus 32 now. Here, a press support column 28 a that supports the press-bonding press mechanism portion 28 is disposed upright at a side position of the set recess 23. The surface of the support column 28a on the side of the set recess 23 is formed as a curved recess that is recessed toward the side away from the set recess 23 so as to avoid a turning trajectory of the crimping main body 36 described later (see FIG. 1).

  In the present embodiment, since it is assumed that terminals are crimped to both ends of the electric wire W, two crimping configurations such as the set recess 23 and the crimping press mechanism 28 are provided. Below, it demonstrates focusing on the structure which crimps | bonds a terminal to the one end side of the electric wire W. FIG.

<3. Explanation of exchange device>

The replacement rack 40 is connected to the terminal crimping table 22 and the press mechanism 28 for crimping. The terminal molding die device 32 is exchanged by taking it in and out.

  The replacement rack 40 itself may be manually set and exchanged with the terminal crimping table 22, but in the present embodiment, it is configured to automatically set and exchange with the terminal crimping table 22. . Hereinafter, the configuration of each part will be described.

<3.1. Replacement rack>
FIG. 5 is a side view showing the replacement rack 40, FIG. 6 is a rear view showing the replacement rack 40, FIG. 7 is a plan view showing the replacement rack 40, and FIGS. FIG. 6 is an explanatory view showing a rotation operation of a terminal molding die device 32 in a rack 40.

  The replacement rack 40 includes a replacement frame 42, a terminal molding tool 32, and a reel support portion 48.

  The replacement frame 42 is a portion that forms the basic skeleton of the replacement rack 40, and includes a pillar portion 43, a lower frame portion 44, and a support base portion 46.

  The column part 43 is a rod-shaped member formed of metal or the like, and is disposed along the vertical direction.

  The lower frame portion 44 is an elongated plate-like member formed of metal or the like, and the lower end portion of the column portion 43 is connected and fixed in an orthogonal posture at the center portion in the longitudinal direction. Wheels 45 are provided at both ends of the lower frame portion 44. Then, the main exchange frame 42 can be easily moved by rolling the wheels 45 on the floor surface with the main exchange rack 40 removed from the main exchange device 30.

  The support base 46 is formed as an elongated plate-like member made of metal or the like. The width dimension of the support base 46 is substantially the same as the width of the terminal molding die device 32 and is also substantially the same as the width of the set recess 23.

  The support base 46 is movably supported on a pair of guide members, which will be described later, so that the terminal base 46 and the press press mechanism 28 are connected along the direction intersecting the transport line L. It is supported movably. However, the support base 46 may be movable along the direction intersecting the transport line L by wheels or the like provided below the replacement frame 42. In the present embodiment, the support base 46 is described as an example of moving along a direction orthogonal to the transport line L. It may be.

  A support shaft portion 47 is provided at one end of the support base portion 46, and the mold support base portion 34 of the terminal molding die device 32 is rotatably supported by the support shaft portion 47. The support shaft portion 47 protrudes below the support base portion 46. Then, in a state where the main support base 46 is disposed in the set recess 23, the support base 46 is fixed to a fixed position using the support shaft portion 47.

  A terminal feed recess 46g is formed at one end of the support base 46. The terminal feed recess 46g has a portion that is recessed over the entire width direction at one end of the support base 46, and an L-shape that is recessed from one side of the recess along the longitudinal direction of the support base 46. Is formed. Then, a chain terminal T, which will be described later, is sent toward the terminal molding die device 32 through the terminal feeding recess 46g.

  Further, a frame feed protrusion 46p is formed at the other end of the support base 46. Here, the frame feeding projection 46p is formed in a short bar shape, and the exchange rack 40 can be taken in and out of the terminal crimping table 22 and the crimping press mechanism 28 using the frame feeding projection 46p. Done.

  The terminal molding die device 32 includes a long and narrow rectangular die supporting base 34 and a crimping main body 36.

  The mold support base 34 is formed to have substantially the same width as the support base 46, and the length dimension of the mold support base 34 is shorter than the length dimension of the support base 46. One end of the mold support base 34 is rotatably supported on the upper surface side of one end of the support base 46 via the support shaft 47. In addition, a chain terminal guide portion 35 that guides the chain terminal T fed from below along the vertical direction and guides it to the terminal molding die device 32 is provided at one end of the mold support base 34. The chain terminal guide portion 35 is formed by a plate member that extends downward from one end portion of the mold support base portion 34. And the chain terminal T sent from the lower part of this terminal shaping | molding die apparatus 32 passes through the inside of this chain terminal guide part 35, and the one end part upper part of the metal mold | die support base part 34 from one end outer part of the metal mold | die support base part 34 It passes through and is sent to the crimping main body 36. When the chain terminal T is sent toward the crimping main body part 36, the space above the one end of the mold support base 34 secures a passage route for sending the chain terminal T toward the crimping main body part 36 in the horizontal direction. It functions as a space.

  The crimping main body portion 36 includes a pair of crimping dies for crimping the terminal against the end portion of the electric wire W, and the terminal is connected to the end portion of the electric wire W conveyed by the electric wire conveying unit 14. It is configured to be crimpable. The crimping main body 36 is fixedly mounted on the other end of the mold support base 34.

  In a posture in which the longitudinal direction of the mold support base 34 is along the longitudinal direction of the support base 46, that is, in a posture in which the terminal molding die device 32 is disposed along the longitudinal direction of the support base 46, 36 is disposed on the support base 46 (see FIG. 12). This posture is a standby posture. In this state, the chain terminal guide portion 35 is disposed in a recess that is recessed along the width direction of the support base 46 in the terminal feed recess 46g.

  Further, the terminal molding die device 32 is rotated so that the longitudinal direction of the die support base 34 intersects the longitudinal direction of the support base 46 (in this case, orthogonal) and is along the conveying line L, that is, When the terminal molding device 32 is crossed (orthogonal in this case) with respect to the support substrate and is in a posture along the transport line L, the crimping main body portion 36 is in a position protruding sideward from one end portion of the support base portion 46. Arranged (see FIG. 13). This posture is a working posture. In this state, the chain terminal guide part 35 rotates around the support shaft part 47 integrally with the terminal molding tool 32, and is recessed along the longitudinal direction of the support base part 46 of the terminal feed recessed part 46g. Arranged in the recess.

  Note that a posture changing projection 35 b projects from the upper surface of one end of the mold support base 34 around the support shaft 47. More specifically, in the standby posture, a posture changing projection 35 b is projected from a position near one corner of one end of the support base 46. And if this attitude | position change protrusion 35b is moved toward the other end part from the one end part of the support base 46, for example, the terminal molding die apparatus 32 will rotate from the stand-by attitude | position to the working attitude | position around the spindle part 47. (See FIGS. 12 and 13).

  The replacement frame 42 is provided with a reel support portion 48 that rotatably supports the terminal reel 49. Here, the terminal reel 49 has a winding shaft portion 49a and a pair of flange portions 49b, and a chain terminal T in which a plurality of terminals are connected via a connecting band is formed around the winding shaft portion 49a. Thus, it is wound and accommodated between the pair of collar portions 49b. The terminal reel 49 has a flat overall shape along the direction of the pair of flanges 49b. Note that a paper tape P is interposed between the chain terminals T as an interlayer paper. With the paper tape P, the entanglement of the chain terminals T between the layers is suppressed.

  The reel support portion 48 rotatably supports the terminal reel 49 in a posture along the moving direction of the support base portion 46. More specifically, the reel support portion 48 includes a protruding piece 48a that protrudes from the middle portion in the longitudinal direction of the column portion 43, and a support shaft portion 48b that protrudes from the end of the protruding piece 48a. The support shaft portion 48 b has a central axis that is orthogonal to the moving direction of the support base portion 46. Therefore, the terminal reel 49 is rotatably supported around the central axis that is orthogonal to the moving direction of the support base portion 46. As a result, the terminal reel 49 is rotatably supported in a posture along the moving direction of the support base 46. Thereby, in the plan view, the extending direction of the terminal reel 49 and the extending direction of the support base 46 can be aligned in the same direction, and the installation space in the plan view of the replacement rack 40 can be reduced.

  The reel support 48 is provided below the support base 46. For this reason, the chain terminal T pulled out from the terminal reel 49 supported by the reel support portion 48 is guided in the vertical direction through the chain terminal guide portion 35 and then sent toward the crimping main body portion 36.

  In addition, the replacement frame 42 is provided with a guide mechanism 120 that guides the terminal T and detects the state thereof. Here, a guide frame 43g is extended so as to extend in a horizontal posture from the pillar portion 43, and a guide mechanism portion 120 is provided at a tip portion thereof.

  As shown in FIGS. 8 to 10, the guide mechanism unit 120 includes a lower guide unit 122 and an upper guide detection unit 124.

  The lower guide portion 122 is a member formed of a metal plate or the like, and here, a shape in which a plurality of (here, two) curved portions bulging while drawing a gentle curve along the feed direction of the terminal T is formed. It is said that. The lower guide portion 122 is fixedly attached to the distal end portion of the guide frame 43g at a fixed position and a fixed posture.

  The upper guide detection unit 124 includes an upper guide plate part 125 and a dog part 126. The dog portion 126 is a long member, and one end portion thereof is rotatably supported by the tip end portion of the guide frame 43g. The upper guide plate portion 125 is a member formed of a metal plate or the like, and is formed in a shape in which both end portions of the elongated plate-like portion are bent while being gently curved. The upper guide plate portion 125 is attached and fixed to one end portion of the dog portion 126 so as to face the lower guide portion 122. The dog part 126 is fixed in an oblique posture with respect to the lower guide part 122. In a state where no external force is applied, the upper guide plate portion 125 is moved by the weight of the upper end portion of the dog portion 126 and the end portion on the same side of the upper guide plate portion 125 (end portion on the downstream side in the feed direction of the terminal T). The terminal T is in a posture (initial posture) with the end on the downstream side in the feed direction facing downward.

  Further, on the other end side of the dog portion 126, a switch SW1 and a switch SW2 that contact the dog portion 126 and detect the dog are provided. The on / off signals of the switches SW1 and SW2 are given to a control unit described later.

  When the chain terminal T does not exist between the lower guide portion 122 and the upper guide detection portion 124, the lower guide portion 122 assumes the initial posture (see FIG. 8). In this state, the dog part 126 is not in contact with any of the switches SW1 and SW2.

  When the chain terminal T is disposed between the lower guide portion 122 and the upper guide detection portion 124, the upper guide plate portion 125 is lifted by the terminal T as shown in FIG. 125 is a parallel posture (normal feed posture) with respect to the lower guide portion 122. In this state, the dog portion 126 contacts the switch SW1, and a signal corresponding to the contact is sent from the switch SW1 to the control unit.

  Further, when the terminal T is further pulled from the above state as the terminal crimping progresses, as shown in FIG. 10, the end of the upper guide plate portion 125 on the downstream side in the feed direction of the terminal T is lifted by the terminal T, The upper guide plate portion 125 is in a posture in which the end of the terminal T on the downstream side in the feed direction is lifted (over-tensile posture). In this state, the dog portion 126 contacts the switch SW2, and a signal corresponding to the contact is sent from the switch SWs to the control unit.

  A paper tape take-up reel 100 for winding the paper tape P is rotatably supported at a lower portion of the column portion 43. A gear portion 102 that rotates integrally with the paper tape take-up reel 100 is rotatably supported on the opposite side of the paper tape take-up reel 100 across the column portion 43. Here, a paper tape take-up drive unit 110 is provided on the crimping table 22 side. The paper tape take-up drive unit 110 includes a rotation drive unit 111 such as a motor and a gear unit 112 that is rotationally driven by the drive of the rotation drive unit 111. Then, with the replacement rack 40 set on the crimping table 22. The gear portion 102 of the replacement frame 42 and the gear portion 112 of the paper tape take-up driving portion 110 are engaged with each other. Then, when the paper tape take-up drive unit 110 is rotationally driven in response to a command from a control unit described later, the rotational motion is transmitted to the paper tape take-up reel 100 via the gear unit 112 and the gear unit 102. As a result, the paper tape take-up reel 100 is rotationally driven to take up the paper tape P.

  The control unit, which will be described later, winds the paper tape P by rotating the paper tape take-up drive unit 110 when it is determined that an over-tension state has occurred based on the detection signal of the switch SW2. As a result, the terminal reel 49 is rotated in the direction in which the terminal T is fed, and the over-tensioned state of the terminal T is relaxed. When the terminal T is loosened between the terminal reel 49 and the terminal molding device 32, the dog portion 126 returns to the normal feeding posture. When it is determined that the control unit is in the normal feeding posture based on the detection signals of the switches SW1 and SW2, the control unit stops the rotation driving of the paper tape winding drive unit 110 and stops the winding of the paper tape P. By repeating the above process during the terminal crimping process described later, the terminal T is fed toward the terminal molding die device 32 in an appropriate tension state.

  Note that the terminal T may be wound around the terminal reel 49 in the opposite direction as in the replacement rack 40B shown in FIG. Even in this case, the terminal T and the paper tape P can be continuously fed in the same manner as described above by appropriately setting the routing route of the terminal T and the paper tape P.

  In a state where the terminal molding die device 32 is in the standby position, the chain terminal T sent from the terminal reel 49 is not twisted and is sent to the crimping main body 36 through the chain terminal guide part 35. maintain. From this state, when the terminal molding device 32 is rotated to the working position, the chain terminal guide portion 35 is also rotated together with the terminal molding device 32. For this reason, the chain terminal T drawn from the terminal reel 49 is twisted according to the rotation angle of the terminal molding die device 32 (here, 90 degrees), and then reaches the chain terminal guide portion 35, and then the crimping main body. It is sent toward the part 36. Since the chain terminal T is twisted at a portion spanned over a relatively long dimension between the terminal reel 49 and the chain terminal guide portion 35, the chain terminal T is smoothly conveyed regardless of the presence of twist. In addition, since the chain terminal T is twisted mainly at the portion conveyed along the vertical direction, the twist is not easily caught by the chain terminal guide part 35. From this point, the chain terminal T is also subject to the presence of twist. Regardless, it is transported smoothly.

  The replacement rack 40 can be manually inserted into and removed from the terminal crimping table 22, and the terminal molding die device 32 is manually rotated from the standby position to the working position to be transferred to the terminal crimping table 22. It can also be set against. Since the switching apparatus 30 employs a configuration that performs these automatically, each configuration will be described.

Suspended support frames 54b are provided so as to hang from both end portions and intermediate portions of each lateral support frame 54a. A plurality of pairs of guide members 55 are provided so as to span between the hanging support frames 54b before and after the entrance / exit support frame 52. The pair of guide members 55 in each set is arranged in a posture along the transport line L, and is arranged so as to be arranged in a parallel posture. Thereby, the support base 46 is supported in a parallel state by disposing the rack support frame 54 with respect to each pair of guide members 55.

  The pair of guide members 55 are arranged at an interval corresponding to the width of the support base 46, and both side edges of the support base 46 are placed on the pair of guide members 55, so that the support base 46 can move forward with respect to the terminal crimping table 22 along the extending direction between the pair of guide members 55. At this time, the wheels 45 of the replacement rack 40 may be in a state of floating from the floor, or may be configured such that the wheels 45 roll on the floor. Further, a roller or the like may be provided in a portion of the guide member 55 that contacts the support base 46.

  Note that the replacement rack 40 can be inserted into and removed from the rack support frame 54 from behind. Then, by removing the replacement rack 40 from the rack support frame 54, the replacement rack 40 can be replaced with another crimping main body 36 or the like, and maintenance or the like for the crimping main body 36 can be performed.

  The exchange moving mechanism unit 60 moves one of the plurality of replacement racks 40 supported in parallel by the rack support frame 54 by moving the rack support frame 54 along the transfer line L. In the position corresponding to the terminal crimp receiving position, that is, the position corresponding to the set recess 23.

  Here, the exchange movement mechanism unit 60 includes an exchange drive unit 61 configured by a linear actuator such as an air cylinder or a hydraulic cylinder. Here, the exchange drive unit 61 is provided on one side of the front / rear support frame 52 (in this case, the rear part). The exchange drive unit 61 includes a main body 61a fixed to the entrance / exit support frame 52 in a posture along the transport line L, and a movable unit 61b capable of reciprocating in the direction along the transport line L with respect to the main body 61a. It has. One (in this case, the rear) horizontal support frame 54 a of the rack support frame 54 is connected to the movable part 61 b of the replacement drive part 61. The other part (front part) of the rack support frame 54 may be supported by the linear guide 62 so as to be movable along the transport line L. Then, by driving the replacement drive unit 61, the rack support frame 54 moves along the transport line L together with the plurality of replacement racks 40, and one of the plurality of replacement racks 40 supported in a parallel state is moved. It can be arranged at a position corresponding to the set recess 23.

  The configuration for moving the rack support frame 54 along the transport line L is not limited to the above example. For example, the configuration may be such that the front and rear portions of the rack support frame 54 are supported by linear guides, and the portion between them is moved and driven by an exchange drive unit such as a linear actuator.

  The rack advancing / retreating mechanism portion 64 is a transfer line L that is disposed at a position corresponding to the terminal crimp receiving position among the plurality of replacement racks 40, that is, a position disposed at a position corresponding to the set recess 23. Move forward and backward.

  That is, the rack advancing / retracting mechanism 64 includes a rack advancing / retreating drive unit 65 constituted by a linear actuator such as an air cylinder or a hydraulic cylinder. The rack advancing / retracting drive unit 65 is a movable body that is reciprocated along the moving direction of the support base 46 by the main body 65a and the main body 65a fixed to the entrance / exit support frame 52 in a state along the moving direction of the support base 46. Part 65b. The position where the main body portion 65a of the rack advance / retreat driving portion 65 is disposed and fixed is a position corresponding to the terminal crimping receiving position, that is, an outer position of the set recess 23. The movable portion 65b is formed with a U-shaped feed piece 66 that opens downward as viewed from the side (moving direction of the rack support frame 54). The rack advancing / retracting drive unit 65 is at a height position where the frame feed projection 46p on the other end of the support base 46 supported by the rack support frame 54 is fitted into the feed piece 66 from the side. It is fixed to the in / out support frame 52 via a bracket 67.

  When the replacement rack 40 is attached to or removed from the rack support frame 54, the portion between the pair of guide members 55 that is the object of the replacement rack 40 is either outside of the rack advance / retreat drive unit 65. It is arrange | positioned in the position which deviated to the direction. Thus, the replacement rack 40 can be mounted on or removed from the rack support frame 54 without interfering with the feed piece 66.

  Further, when moving one of the plurality of replacement racks 40 toward the terminal crimping table 22, the rack support frame 54 is moved along the transport line L by driving the replacement moving mechanism 60, The target replacement rack 40 is disposed at a position corresponding to the rack advance / retreat drive unit 65, here, at a position immediately below. Then, the frame feed protrusion 46 p is disposed in the feed piece 66. In this state, when the feed piece 66 is moved toward the terminal crimping table 22 by driving the rack advance / retreat driving unit 65, the feed piece 66 pushes the replacement rack 40 toward the terminal crimping table 22. As a result, the replacement rack 40 moves toward the terminal crimping table 22, the support base 46 moves toward the set recess 23, and the terminal molding device 32 is set on the terminal crimping table 22 as will be described later. . From this state, when the feed piece 66 is moved toward the rear of the entrance / exit support frame 52 by driving the rack advance / retreat drive unit 65, the feed piece 66 pushes the replacement rack 40 toward the rear of the entrance / exit support frame 52. . As a result, the replacement rack 40 moves toward the entrance / exit support frame 52 and returns to the rack support frame 54 between the pair of guide members 55. In this manner, the replacement rack 40 is put in and out between the rack support frame 54 and the terminal crimping table 22.

<3.3. Configuration for automatically setting the terminal molding die device>
A configuration for automatically setting the replacement rack 40 on the terminal crimping table 22 will be described. 17 is a schematic plan view showing the terminal crimping table 22 portion, FIG. 18 is a schematic view showing the rack fixing mechanism portion 70, FIG. 20 is a schematic view showing the posture changing mechanism portion 80, and FIG. FIG. 22 is a schematic view showing a changing operation, and FIG. 22 is a schematic view showing a mold apparatus fixing mechanism portion 76.

  As described above, the set recess 23 is formed in the terminal crimping table 22, and the support base 46 moves toward the set recess 23. The set recess 23 is formed to have a length that allows a portion of the support base 46 where the terminal molding die device 32 is disposed to be disposed. The width of the set recess 23 is set smaller (slightly smaller) than the width of the support base 46, and guide rails 23 r are provided on the upper surfaces of both sides of the set recess 23. When the support base 46 moves toward the set recess 23, the support base 46 is sandwiched between the pair of guide rails 23 r, and both side edges thereof are disposed on the upper surfaces of both side edges of the set recess 23.

  A rack fixing mechanism part 70, a posture changing mechanism part 80, and a mold apparatus fixing mechanism part 76 are provided in the vicinity of the set recess 23 in the terminal crimping table 22.

  As shown in FIGS. 17 and 18, the rack fixing mechanism unit 70 fixes the replacement rack 40 in a fixed position with respect to the set recess 23. More specifically, the rack fixing mechanism unit 70 includes a suppression drive unit 72 configured by an actuator such as an air cylinder or a hydraulic cylinder, and a suppression unit disposed so as to be able to advance and retreat by the suppression drive unit 72. Part 74 (see FIGS. 17 and 18). In the suppression driving unit 72, the rack fixing mechanism unit 70 is fixed to one side of the support shaft portion 47 in the set recess 23 and at a position below the terminal crimping table 22. The suppressing portion 74 is formed as an elongated rod-like member, and a concave portion 74g in which the support shaft portion 47 can be disposed is formed on one side surface thereof. The restraining portion 74 is driven forward and backward by the rack fixing mechanism portion 70 toward the support shaft portion 47 that projects downward from the support base portion 46. Then, in a state in which the suppressing portion 74 is retracted, the support base portion 46 moves toward the set concave portion 23, and the support shaft portion 47 is disposed at a position facing the concave portion 74g. In this state, when the suppression portion 74 is driven to advance by driving the suppression drive portion 72, the suppression portion 74 suppresses the support shaft portion 47 in a state where the support shaft portion 47 is fitted in the recess 74g. As a result, the side edge portion of the support base portion 46 that is suppressed is pressed against the guide rail 23r. Thereby, the support base 46 is fixed so that there is no rattling along the width direction. Further, the support base portion 46 is positioned and fixed in the longitudinal direction of the support base portion 46 by fitting the support shaft portion 47 into the concave portion 74g. When the replacement rack 40 is retracted, the suppression unit 74 is retracted by driving the suppression drive unit 72, and the fixed state is released.

  As shown in FIGS. 17, 20, and 21, the posture changing mechanism unit 80 changes the posture of the terminal molding die device 32 from the standby posture to the working posture in a state where the support base 46 has moved forward into the transport line L. At the same time, before the support base 46 is retracted from the conveying line L, the terminal molding die device 32 is changed from the working posture to the standby posture.

  More specifically, the posture change mechanism unit 80 includes a posture change drive unit 82, a locking drive unit 84, and an operating piece 86.

  The attitude change drive unit 82 is configured by a linear actuator such as an air cylinder or a hydraulic cylinder, and is fixed to one side of the set recess 23 and above the terminal crimping table 22.

  The locking drive unit 84 is configured by a linear actuator such as an air cylinder or a hydraulic cylinder. The locking drive unit 84 is reciprocally driven linearly along the extending direction of the set recess 23, that is, the advancing / retreating direction of the support base 46 by the posture changing drive unit 82.

  The operating piece 86 is formed in a U-shaped member that opens downward when viewed from the side of the set recess 23, and is supported so that it can be moved up and down by the locking drive unit 84 with the opening facing downward. Has been. The operating piece 86 is reciprocally driven linearly along the extending direction of the set recessed portion 23 together with the locking drive portion 84 by the posture change drive portion 82.

  In a state where the support base 46 is disposed in the set recess 23, the operating piece 86 is disposed above the posture changing projection 35b. Note that the posture changing projection 35b is set to be sufficiently long so as not to be disengaged from the U groove of the operating piece 86. In this state, the operating piece 86 is lowered by the driving of the locking drive portion 84, and the posture changing projection 35b is disposed in the opening. In this state, the operation piece 86 is retracted from the transport line L together with the locking drive unit 84 by driving the posture change drive unit 82. Then, the posture changing projection 35b also moves away from the transport line L. At this time, a groove extending in the direction crossing the set recess 23 is formed in the operating piece 86, and the posture changing projection 35b is fitted into the groove and can move along the extending direction of the groove. For this reason, the posture changing projection 35b moves along the extending direction of the set recess 23 while moving along the width direction of the set recess 23, and draws an arc-shaped locus centering on the support shaft portion 47. Can move. As a result, the posture changing projection 35b is pushed by the operating piece 86 and moves along an arcuate locus, whereby the terminal molding die device 32 can change its posture from the standby posture to the working posture. In addition, when the operating piece 86 moves in the opposite direction, the terminal molding die device 32 can change its posture from the working posture to the standby posture. In this state, the operating piece 86 is moved upward to release the engagement between the operating piece 86 and the posture changing projection 35b, and the support base 46 can be retracted from the set recess 23. .

  In addition, as shown in FIG. 19, you may change the attitude | position of the terminal molding die apparatus 32 using the rack 130 and the pinion gear part 132. FIG. In this case, the pinion gear portion 132 is integrally attached to the support shaft portion 47, and a rack 130 is disposed at a position where the pinion gear portion 132 can be engaged with the pinion gear portion 132. The rack 130 is connected to a linear motor or an air cylinder or the like. The attitude of the terminal molding die device 32 may be changed by reciprocating driving by another pinion gear that is rotationally driven by a drive mechanism or a motor. In this case, when the support base 46 is disposed in the set recess 23, the rack 130 may be moved by a separate moving mechanism and meshed with the pinion gear portion 122. If the support base 46 is disposed in the set recess 23, the rack 130 and the pinion gear portion 132 may be in a positional relationship.

  As shown in FIG. 17 and FIG. 22, the mold device fixing mechanism 76 is engaged with the terminal molding device 32 to maintain the posture in a state where the terminal molding device 32 is changed to the working posture. Is configured to do. Here, the mold apparatus fixing mechanism portion 76 includes a receiving piece 77 and a lock mechanism portion 78. The receiving piece 77 is fixed on the terminal crimping table 22, and in a state in which the terminal molding die device 32 is changed from the standby posture to the working posture, the contact piece 77 abuts on the terminal molding die device 32 and restricts further rotation. It is configured as a receiving piece. The lock mechanism portion 78 is provided on the side portion on the opposite side of the receiving piece 77 in a state in which the terminal molding device 32 is changed to the working posture. That is, the lock hole 22 h is formed at a position corresponding to the side portion on the opposite side of the receiving piece 77 in a state where the terminal molding device 32 is in the working posture in the terminal crimping table 22. The lock mechanism portion 78 includes a lock piece 79a and a lock drive portion 79b. The lock piece 79a is a long piece having a claw portion, and is rotatably supported at a position below the terminal crimping table 22 and corresponding to the locking hole portion 22h. An unlocked position retracted downward from the upper surface of 22 (see a solid line in FIG. 22), and a locked position in which the claw portion protrudes from the upper surface of the terminal crimping table 22 and can be locked to the side portion of the terminal molding die device 32. The posture can be changed between The lock driving portion 79b is configured by a linear actuator such as an air cylinder or a hydraulic cylinder, and drives the lock piece 79a to swing between an unlocked posture and a locked posture.

  Then, in a state where the lock piece 79 a is in the unlocked posture, the terminal molding die device 32 changes the posture to the working posture through the upper side of the lock piece 79 a and comes into contact with the receiving piece 77. In this state, when the lock piece 79a is changed from the non-locking posture to the locked posture by driving the lock driving portion 79b, and the claw portion is engaged with the terminal molding tool 32 from the opposite side of the receiving piece 77, the terminal The molding die device 32 is maintained in the locked posture. In this state, the crimping press mechanism portion 28 is disposed above the terminal molding die device 32, and the terminal molding die device 32 can perform the terminal crimping operation by driving the crimping press mechanism portion 28. .

  In the above state, when the lock piece 79a is changed from the locked position to the non-locked position by driving the lock driving portion 79b, the terminal molding die device 32 can be changed from the working position to the standby position. Become.

  In addition, the structure which performs the attitude | position change of the terminal shaping die apparatus 32 is not restricted to the said example. The posture changing mechanism unit may be mounted on the replacement rack 40 itself. Further, the timing for changing the posture does not have to be a state in which the support base 46 is moved to the set recess 23 and stopped. You may make it change the attitude | position of the terminal shaping | molding die apparatus 32 in the middle of the support base part 46 advancing movement with respect to the set recessed part 23, ie, the conveyance line L, or retreating.

<4. Operation explanation>
Operation | movement of the exchange apparatus 30 of the terminal shaping die apparatus 32 is demonstrated. The switching apparatus 30 includes a control unit configured by a microcomputer including a microprocessor, a main storage unit coupled to the microprocessor, and an auxiliary storage unit. The following operations are performed according to instructions described in a program stored in the auxiliary storage unit.

  First, as shown in FIG. 23, it is assumed that the terminal can be crimped to the end portion of the electric wire W conveyed along the conveyance line L by the one terminal molding die device 32. In this state, one support base 46 is moved forward with respect to the transport line L (set in the set recess 23), and the other support base 46 is located away from the transport line L. This is a state (a state supported by the rack support frame 54). In this state, the terminal arrangement direction when crimping the terminals in the crimping main body 36 is a direction orthogonal to the transport line L. That is, the grooves of the pair of terminal crimping molds of the crimping main body 36 extend in a direction orthogonal to the transport line L. For this reason, a terminal can be supplied in the form of a chain terminal from the side of the crimping main body 36. In addition, the terminal can be crimped to the end of the electric wire W that is transported in a posture orthogonal to the transport line L. For this reason, when performing terminal crimping, it is not necessary to change the direction of the end portion of the electric wire W, and therefore the configuration of the electric wire transport unit 14 can be simplified.

  When the terminal to be crimped is exchanged, that is, when the terminal molding die device 32 is exchanged, the following operation is performed.

  That is, as shown in FIG. 24, the terminal molding die device 32 is moved from the working posture to the standby posture by driving the posture change driving portion 82 in a state where the receiving piece 77 is unlocked by driving the lock mechanism portion 78. Change it. Thereafter, the locking of the operating piece 86 and the posture changing projection 35b is released by driving the locking driving portion 84. Further, the suppression of the support base 46 by the suppression unit 74 is released by driving the suppression drive unit 72.

  Thereafter, as shown in FIG. 25, the rack 40 for replacement including the support base 46 that has been advanced is retracted toward the rack support frame 54 by driving the rack advance / retreat drive unit 65.

  Next, as illustrated in FIG. 26, the rack support frame 54 is moved along the transport line L by driving the replacement drive unit 61, and includes a plurality of (two) support bases 46 in parallel. One of the racks 40 is moved to a position (here, a position corresponding to the rack advance / retreat driving unit 65) corresponding to the terminal crimping receiving position (here, the position of the set recess 23). Then, the posture changing projection 35b of the support base 46 on the one side is disengaged laterally from the inside of the feed piece 66, and instead, the posture changing projection 35b of the support base 46 on the other side is placed in the feed piece 66. It is arranged from the side.

  Next, as shown in FIG. 27, the rack 40 for replacement including the other support base 46 moves forward from the rack support frame 54 toward the terminal crimping table 22 by driving the rack advance / retreat drive unit 65. Then, the support base portion 46 is suppressed and fixed by the suppression portion 74 by the drive of the suppression drive portion 72.

  Then, as shown in FIG. 28, the operating piece 86 and the posture changing projection 35 b are locked by driving the locking driving portion 84, and in this state, the terminal molding die device is driven by driving the posture changing driving portion 82. The posture is changed from the standby posture to the working posture. Then, when the receiving piece 77 is locked to the terminal molding die device 32 by driving the lock mechanism portion 78, the setting of the terminal molding die device 32 is completed, and the force of the crimping press mechanism portion 28 above is received. Thus, the crimping main body 36 can perform the terminal crimping operation.

  In this state, terminal crimping is performed on the end of the wire W transported by the wire transport unit 14.

  According to the exchange device 30 of the terminal molding die device 32 configured as described above, the terminal molding die device 32 and the terminal reel 49 are both moved forward and backward with respect to the transport line L by moving the entire replacement rack 40. You can move them and exchange them all at once. Further, when the terminal molding device 32 is moved forward and backward from the transfer line L, the terminal molding device 32 is set in a standby posture along the moving direction of the support base 46. For this reason, the movement locus can be made small, and the installation area can be made as small as possible. Further, even when the terminal molding die device 32 is retracted from the conveying line L, the plurality of terminal molding die devices 32 can be put on standby in a parallel posture arranged along the moving direction of the support base 46. The waiting area can be made compact.

  Further, when the terminal molding die device 32 is moved forward toward the conveyance line L and the terminal is crimped to the end of the electric wire W, the terminal molding die device 32 is changed to a working posture. The end portion of the electric wire W conveyed along the conveying line L can be disposed between a pair of molds and subjected to terminal crimping without changing the direction thereof. For this reason, it is not necessary to incorporate the structure etc. which change the direction of the edge part of the electric wire W in the electric wire conveyance unit 14 or its periphery, and simplification of a structure is achieved.

  In addition, while the support base 46 is moving forward or moved to the transport line L, the terminal molding device 32 is changed from the standby posture to the working posture, and the support base 46 is retracted from the transport line L. Since it includes the posture change drive unit 82 that changes the terminal molding die device 32 from the working posture to the standby posture before or during retraction, the support base 46 is moved forward and backward with respect to the transport line L. The posture of the terminal molding die device 32 can be automatically changed.

  Further, a reel support portion 48 is provided below the support base portion 46, and the terminal molding die device 32 is designed with the chain terminal T drawn from the terminal reel 49 supported by the reel support portion 48 along the vertical direction. Since the chain terminal guide portion 35 guided to the terminal rotates integrally with the terminal molding die device 32, the chain terminal T can be smoothly moved even when the terminal molding die device 32 is changed to the working posture. 32 can be guided.

  In addition, a rack support frame 54 that supports a plurality of replacement racks 40 in a parallel state at positions away from the transfer line L, and one of the replacement racks 40 supported by the rack support frame 54 is connected to a terminal crimp receiving position. An exchange moving mechanism 60 for moving the rack support frame 54 so as to be arranged at a position corresponding to the position, and a rack advance / retreat mechanism for moving the exchange rack 40 arranged at the terminal crimp receiving position forward and backward with respect to the transport line L. Since the part 64 is provided, the plurality of replacement racks 40 can be automatically replaced, which is convenient.

  In the above-described embodiment, as shown in FIG. 29, the crimping main body portion 36 turns around the support shaft portion 47 and is disposed below the crimping press mechanism portion 28. For this reason, it is necessary to set the crimping | compression-bonding main-body part 36 with respect to the press mechanism part 28 for crimping | bonding along the direction Q (that is, the setting direction of the edge part of the electric wire 13).

  As a general crimping main body part 36, there is a type in which a press mechanism part for crimping is set from the side, and a configuration for allowing such a type of crimping main body part 36 to be applied to the present embodiment. explain.

  First, as shown in FIG. 30, a set recess 132 is formed on the upper part of the movable part 130 that receives the force for raising and lowering the upper die (also referred to as a crimper) in the crimping main body portion 36 of the terminal molding die device 32. Yes. The set recess 132 is formed in a concave shape that is recessed from one side of the movable part 130 toward the center of the movable part 130. The upper opening of the set recess 130 is formed to be narrower than its bottom, and a pair of set grooves 133 are formed on the inner side (lower side).

  The set concave portion 130 is a portion into which the press force applying portion 140 of the press bonding press mechanism portion is inserted and fitted. In other words, the pressing force application part 140 has a shape in which a disk-shaped flange 142 is formed at the lower end of the short cylindrical part. Then, it is inserted and fitted into the set recess 130 from the first direction from the side opening side. When the collar 142 is fitted into the pair of set grooves 133, the movable part 130 is driven up and down together with the pressing force application unit 140 along with the up and down driving by the press mechanism for press bonding. The press-bonding press mechanism portion 28 in the present embodiment also includes a press force applying portion 140 similar to the above (see FIGS. 31 and 33).

  The next press force relay mechanism 150 is attached above the movable part 130.

  As shown in FIGS. 30 to 33, the press force relay mechanism unit 150 includes a relay fitting portion 152 and a relay main body portion 154 in which a relay set recess 156 is formed.

  The relay main body 154 is formed in a block shape from metal or the like, and a relay set recess 156 having the same shape as the set recess 130 is formed on the relay main body 154. However, the side opening direction of the relay set recess 156 is different from the side opening direction (first direction) of the set recess 130. That is, the lateral opening direction of the relay set recess 156 is such that when the crimping main body part 36 moves around the support shaft part 47 and the crimping main body part 36 moves below the crimping press mechanism part 28, It opens toward the moving direction of the crimping main body 36. Therefore, the pressing force applying unit 140 is in a direction different from the first direction and in a direction along the moving direction when the terminal molding die device 32 moves below the press-bonding pressing mechanism unit 28. The pressing force applying portion 140 can be inserted and fitted into the relay set recess 156.

  Of the both sides of the relay set recess 156, the side portion 156a on the inner peripheral side of the circle around which the terminal molding die device 32 rotates is inclined outward toward the side opening direction of the relay set recess 156. It is extended. That is, according to the turning of the terminal molding die device 32, the pressing force applying unit 140 is inserted and fitted into the relay set recess 156 while drawing an arc shape from the side of the inner peripheral side of the relay set recess 156, The pressing portion 140 is smoothly fitted into the relay set recess 156 by inclining the side portion by the arcuate locus.

  In addition, a circular bottomed recess 157 is formed at the bottom of the relay main body 154. A screw insertion hole 158 is formed between the bottomed recess 157 and the relay set recess 156.

  The relay fitting portion 152 is formed of metal or the like, and has a shape in which disc-shaped flange portions 152a and 152b are formed at both ends of the short cylindrical portion.

  One brim 152a is formed so as to be able to fit into the bottomed recess 157. In addition, a screw hole 152as corresponding to the screw insertion hole 158 is formed in the flange portion 152a. Then, the screw S is fastened to the screw hole 152as through the screw insertion hole 158, so that the relay fitting portion 152 is fixed so as to be drawn toward the relay main body portion 154.

  The other flange 152b is formed so as to be inserted and fitted into the pair of grooves 133 of the set recess 130. When the screw S is tightened in a state where the flange portion 152b is inserted and fitted into the pair of groove portions 133, the other flange portion 152b is attracted to the relay main body portion 154, and the press force relay mechanism portion 150 is moved to the movable portion 130. Mounted and fixed on top.

  If this relay mechanism part 150 is used, the insertion fitting direction of the press force provision part 140 can be changed. Thereby, as the crimping main body portion 36, a configuration in which the press force applying portion 140 can be inserted and fitted from the side is originally used, and the press force applying portion 140 is relay fitted by the swiveling movement of the crimping main body portion 36. It can be easily fitted into the portion 152.

  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.
