Hereinafter, the wire processing apparatus according to the embodiment will be described.

<Cable>
First, the cable 10 (refer FIG. 2) which is a process target of the said wire processing apparatus is demonstrated. The cable 10 includes a plurality (three in the example illustrated in FIG. 2) of covered wires 12 and a sheath 16 that covers the periphery of the plurality of covered wires 12. Each covered electric wire 12 has a conductor core wire 13 and an insulating coating 14 covering the periphery of the conductor core wire 13 (see FIG. 5). Here, the cable 10 includes a shield layer (not shown) and a drain line 15 connected to the shield layer. It is conceivable that the shield layer is made of, for example, a metal foil or a metal braid, and is provided on the inner peripheral side of the sheath 16. In addition, the drain wire 15 may be configured by, for example, a bare conductor core wire and provided so as to be electrically connected to the shield layer on the inner peripheral side of the sheath 16. Accordingly, here, the description will be made assuming that the cable 10 is a shielded cable. However, it is not essential that the cable 10 includes the shield layer and the drain wire 15, and the cable 10 may be a cable other than the shield cable.

  The cable 10 immediately before being processed by the electric wire processing apparatus is cut into a predetermined length from the long cable 10 and the sheaths 16 at both ends 10a and 10b are peeled off. Therefore, the covered electric wire 12 is exposed from the end portions 10 a and 10 b of the cable 10. At this time, the drain wire 15 is also exposed on the one end 10a side of the cable 10 here. However, the drain wire 15 may be exposed on both ends 10 a and 10 b of the cable 10. At this time, the end 12a of the covered electric wire 12 is not peeled off.

  And the terminal 17 (refer FIG. 5) is crimped | bonded to the edge part 12a of each covered electric wire 12 of the cable 10 by processing the cable 10 with this electric wire processing apparatus 20. FIG.

<Overall configuration of wire processing equipment>
Next, the whole structure of an electric wire processing apparatus is demonstrated. FIG. 1 is a schematic diagram illustrating an overall configuration of an electric wire processing apparatus 20 according to the embodiment.

  The electric wire processing apparatus 20 collectively feeds a plurality of covered electric wires 12 of the cable 10 along the conveyance path in a state where the end portions 12a are held, and passes the held end portions 12a of the covered electric wires 12 along the conveyance path. It is an apparatus which processes in order by the electric wire processing part 60 arranged side by side. As the said process process, for example, the front end cutting process which cuts the front-end | tip of the edge part 12a of the hold | covered covered electric wire 12 in order, and the peeling process which peels off the insulation coating 14 of the edge part 12a of the covered electric wire 12 trimmed And a crimping step of crimping the terminal 17 to each exposed core wire of the peeled end portion 12a. As other steps, for example, a rubber plug insertion step of passing a rubber plug through the electric wire 12 and an inspection step of inspecting the crimped terminal 17 may be performed. In addition, the both ends 12a of all the covered electric wires 12 among the cables 10 may be sent at a time, or only the ends 12a of some of the covered electric wires 12 may be sent. When only the end 12a of some covered electric wires 12 is sent, only the end 12a of the covered electric wire 12 located at one end of the cable 10 may be sent, or the covered electric wires located at both ends of the cable 10 may be sent. There may be a case where twelve end portions 12a are mixed and sent.

  Specifically, the electric wire processing apparatus 20 includes an electric wire setting unit 30, an electric wire transport unit 40, an electric wire supply unit 50, an electric wire processing unit 60, an electric wire discharge unit 80, and a control unit 120.

  The electric wire set part 30 is provided so that the end part 12a of the some covered electric wire 12 contained in the one cable 10 can be set. In the electric wire set part 30, the edge part 12a of the some covered electric wire 12 contained in the cable 10 is set by the operator. Below, the edge part 12a of the some covered electric wire 12 set to the electric wire set part 30 at once is called the edge part group 12g. Then, in a state where the end group 12g is set in the electric wire set unit 30, the end group 12g set in the electric wire set unit 30 is conveyed to the electric wire conveying unit 40 by the operator turning on the start switch. The

  The electric wire transport unit 40 sends the end group 12g along the transport path. Here, the end group 12g set in the electric wire set unit 30 is collectively supplied to the upstream side of the electric wire transport unit 40 by the electric wire supply unit 50. The supplied end group 12g is transported from the upstream side to the downstream side of the transport path by the electric wire transport unit 40.

  In the electric wire processing unit 60, the skin peeling unit 64, the crimping unit 70, and the like are provided so as to be arranged along the transport path, and sequentially process the transported end group 12g. At this time, the crimping portion 70 has a plurality of crimping mechanisms 71 and can crimp different terminals 17 for each crimping mechanism 71. The crimping mechanism 71 that performs the crimping process on each end 12a of the end group 12g among the plurality of crimping mechanisms 71 is determined by the control unit 120. And the terminal 17 is crimped | bonded to the edge part 12a by the crimping | compression-bonding mechanism 71 where the crimping | compression-bonding instruction | command was issued by the control part 120. FIG. Therefore, each crimping mechanism 71 crimps the terminal 17 to the end 12a when the end 12a to which the crimping command is issued is conveyed out of the end group 12g, and no crimping command is issued. When the end 12a is conveyed, the terminal 17 is not crimped.

  The end group 12g that has been processed is transported to the downstream side of the transport path by the electric wire transport unit 40 as it is. The end group 12g conveyed to the downstream side of the conveyance path is collectively discharged by the electric wire discharge unit 80. Thereby, the cable 10 by which the terminal 17 was crimped | bonded to each edge part 12a of the some covered electric wire 12 is obtained.

  Next, each part of the electric wire processing apparatus 20 will be described in detail.

<Wire set part>
First, the electric wire set part 30 is demonstrated with reference to FIG.2 and FIG.3. FIG. 2 is a schematic plan view showing the electric wire setting unit 30. FIG. 3 is a schematic front view showing the wire setting unit 30 and the wire supply unit 50. Specifically, the electric wire setting unit 30 includes a setting unit 31 and an elevating / lowering mechanism 39.

  The setting unit 31 is a place where an operator sets the end 12 a of the covered electric wire 12. The setting unit 31 includes a setting table 32, a holding unit 33, a holding detection unit 36, an allowance detection unit 37, and an extension suppressing unit 38.

  The set table 32 is formed, for example, as a flat surface having a rectangular upper surface. The set base 32 supports the holding unit 33, the holding detection unit 36, and the allowance detection unit 37.

  The holding part 33 holds the end part 12 a of the covered electric wire 12. Here, the holding part 33 includes six pairs of holding claws 34 each capable of holding the end 12a of the covered electric wire 12. The positional relationship of the six pairs of holding claws 34 is provided such that the six covered electric wires 12 having the end portions 12a held by the respective holding claws 34 are in parallel.

  Each holding claw 34 is provided so that it can be opened and closed individually. Here, at least the state change of the holding claw 34 from the closed state to the open state is controlled by a cylinder or the like. The change of the holding claw 34 from the open state to the closed state may be performed by an operator when the covered electric wire 12 is set, or may be performed by the cylinder.

  The holding detection unit 36 detects that the end 12 a of the covered electric wire 12 is held by the holding unit 33. For example, a stopper bolt provided at the lower end of each holding claw 34 and a stopper pin provided at the upper end of the cylinder for controlling the opening and closing of each holding claw 34 may be one of the holding claw 34 in an open state and a closed state. The holding detector 36 detects whether the holding claw 34 is in an open state or a closed state, and the covered electric wire 12 is held by each holding claw 34 by being provided so as to be in contact and not in contact with the other. It is detected whether or not

  The allowance allowance detection unit 37 detects the amount of extension on the tip side of the end 12 a of the covered electric wire 12 with respect to the portion held by the holding unit 33. For example, the allowance detection unit 37 is configured by a transmission sensor in which the light projecting unit and the light receiving unit are separated from each other, and is provided on the side where the tip of the covered electric wire 12 is positioned with respect to the holding unit 33. Here, a transmission sensor is provided for each holding claw 34. Each transmission sensor detects that the tip of each covered electric wire 12 extending from each holding claw 34 is longer than a predetermined length (first threshold) (or longer). Here, the first threshold is a value set experimentally and experimentally, and the extension amount on the tip side of the portion of the covered electric wire 12 held by the holding portion 33 is greater than or equal to the first threshold. Processing mistakes in the processing steps are suppressed.

  The extension suppressing unit 38 suppresses the extension amount on the distal end side from the portion held by the holding unit 33 in the covered electric wire 12 exceeding the second threshold value. For example, the extension suppressing portion 38 is formed in a long plate shape, and is provided on the distal end side of the covered electric wire 12 with respect to the holding portion 33 at a position separated by the second threshold dimension. By providing the extension suppressing portion 38, it is possible to prevent the extension amount on the tip side from becoming too long compared to the portion held by the holding portion 33 in the end portion 12 a of the covered electric wire 12. Thereby, it is suppressed that the front-end | tip of the covered electric wire 12 is cut too much and becomes short.

  By providing the allowance detecting unit 37 and the extension suppressing unit 38, the extension amount of the covered electric wire 12 held by the holding unit 33 from the holding unit 33 is in a range between the first threshold value and the second threshold value. It will fit.

  The raising / lowering moving mechanism 39 raises / lowers the holding portion 33 (here, the setting unit 31) between the set position SP where the covered electric wire 12 is set and the first delivery position HP1 which delivers the end group 12g to the supply chuck 51. Move. The elevating / lowering mechanism 39 is constituted by, for example, an air cylinder, a hydraulic cylinder, a linear motor, or the like.

<Electric wire conveyor>
Next, the electric wire conveyance part 40 is demonstrated with reference to FIG. FIG. 4 is a schematic front view showing the electric wire supply unit 50 and the electric wire transport unit 40. As described above, the electric wire conveyance unit 40 sends the end group 12g along the conveyance path. Specifically, the electric wire transport unit 40 includes a gripping unit 42, a transport unit 45, and a state change operation execution unit 48.

  The grip portion 42 can grip the end portion 12 a of the covered electric wire 12. Here, one gripping unit 41 is constituted by three gripping portions 42. The gripping unit 41 includes a support portion 43 and a state changing portion 44 in addition to the above three gripping portions 42. The interval between the adjacent gripping portions 42 in one gripping unit 41 and the interval between the adjacent gripping portions 42 located at each end of the two adjacent gripping units 41 are set to be the same.

  The grip part 42 is composed of a pair of claw parts 42a. The claw part 42 a is formed in a long bar shape, and the base end is supported by the support part 43 with the distal ends separated from each other. The state can be changed to positions close to each other by the state changing unit 44.

  The support unit 43 is supported by a belt 46 (described later) of the transport unit 45 and rotates together with the belt 46. The support portion 43 supports the grip portion 42 on the outer peripheral side of the belt 46. In addition, the support unit 43 supports the state change unit 44.

  The state changing unit 44 changes the state of the three gripping units 42 between the open state and the closed state. Here, the state changing unit 44 includes a first portion 44a formed in a rectangular plate shape and a second portion 44b interlocked with the first portion 44a. The base end of the second portion 44 b is continuous with the first portion 44 a, and the tip protrudes toward the inner peripheral side of the belt 46. Three through holes are formed in the first portion 44a. The three through holes are respectively inserted through the intermediate portions in the extending direction of the three gripping portions 42. The first portion 44 a is supported by the support portion 43 in such a manner that the first portion 44 a can move toward and away from the support portion 43 along the extending direction of the grip portion 42. Since the first portion 44a is located at a position close to the support portion 43, the tips of the pair of claw portions 42a are opened, and the end portion 12a of the covered electric wire 12 can be taken in between the pair of claw portions 42a. In addition, since the first portion 44a is located at a position separated from the support portion 43, the ends of the pair of claws 42a are closed, and the end 12a of the covered electric wire 12 is held between the pair of claws 42a. Can be maintained. The approaching and separating movement of the first portion 44a is performed by the state change operation execution unit 48 via the second portion 44b.

  The conveyance unit 45 sequentially conveys the plurality of gripping units 42 from the upstream side to the downstream side along the conveyance path. The transport unit 45 transports the end group 12g at a height corresponding to the height of the holding unit 33 raised by the elevating / lowering mechanism 39. Here, the transport unit 45 is configured by an endless conveyor including an endless belt 46 and a driving unit 47 that rotationally drives the belt 46. The drive unit 47 is constituted by, for example, a stepping motor or a servo motor, and can feed the belt 46 at a predetermined pitch. Therefore, the conveyance part 45 is comprised so that the edge part group 12g can be sent with a predetermined pitch.

  The state change operation execution unit 48 is fixed at a position corresponding to the first delivery position HP1, and is provided so as to change the state of the state change unit 44 of the gripping unit 41 located at the first delivery position HP1 with respect to the transport unit 45. ing. The state change operation execution unit 48 is configured by, for example, a cylinder 48a. An engagement member 49 formed in a hook shape is provided at the first delivery position HP1, and when the gripping unit 41 is located at the first delivery position HP1 with respect to the transport unit 45, the engagement member 49 is located on the cylinder 48a. The groove 48h formed at the tip engages with the groove 44h formed at the tip of the second portion 44b. Then, the piston movement of the cylinder 48a is transmitted to the second portion 44b via the engaging member 49, and the second portion 44b moves up and down, so that the first portion 44a also moves up and down, thereby opening the claw portion 42a. Change state between closed state. Here, the state can be changed from an open state in which the end group 12g can be received from the electric wire supply unit 50 to a closed state in which the received end group 12g can be gripped. The state change operation execution unit 48 is also provided at a position corresponding to a second delivery position HP2 described later, and when the end group 12g is ejected, the claw portion 42a of the gripping unit 41 located at the second delivery position HP2. Is changed from closed to open.

  Here, the length at which the sheath 16 is peeled off from the cable 10 is appropriately determined. In the case of the shielded cable 10, the length at which the sheath 16 is peeled off is as short as possible in order to suppress the deterioration of the shielding effect. Is preferred. However, when the length to which the sheath 16 is peeled in this way is short, or when the number of the covered electric wires 12 is large, the ends 12a of the plurality of covered electric wires 12 are opened with the crotch of the covered electric wires 12 in one set. It is difficult to set each to a processable state. However, even in this case, the amount of peeling of the sheath 16 is small by setting the interval between the adjacent gripping portions 42 to a value according to the width dimension of the crimping die (herein, upper die 72 and lower die 73 described later). Even with an electric wire, as many end portions 12a as possible can be set in the electric wire setting portion 30 at a time.

<Wire supply section>
Next, the electric wire supply part 50 is demonstrated, referring FIG.3 and FIG.4. The electric wire supply part 50 is provided so that the end part group 12g set to the electric wire setting part 30 can be collectively replaced by the holding part 42. FIG. Specifically, the electric wire supply unit 50 includes a supply chuck 51 and a supply movement mechanism 56.

  The supply chuck 51 can chuck the end portions 12 a of the plurality of covered electric wires 12. The supply chuck 51 includes a first supply chuck 54 and a second supply chuck 55. Each of the supply chucks 54 and 55 includes a first plate portion 52, a second plate portion 53, and a cylinder (not shown) that relatively moves the first plate portion 52 and the second plate portion 53. The 1st board part 52 and the 2nd board part 53 are provided so that main surfaces may oppose. Three concave portions 52h and 53h are formed in the first plate portion 52 and the second plate portion 53, respectively. Then, by sliding the first plate portion 52 and the second plate portion 53 with a cylinder or the like, an open state where the overlap of the recesses 52h and 53h is large and a closed state where the overlap of the recesses 52h and 53h is small It is possible to change the state. Accordingly, each of the supply chucks 54 and 55 can chuck the three end portions 12a together. Among the six recesses 52h and 53h in total of the two supply chucks, the interval between the adjacent recesses 52h and 53h is set to be the same. Further, the interval between the adjacent recesses 52h and 53h of the supply chuck 51, the interval between the adjacent gripping portions 42, and the interval between the adjacent holding claws 34 of the holding portion 33 are set to be the same.

  The supply movement mechanism 56 is located between a position corresponding to the electric wire setting unit 30 (the setting position SP) for the supply chuck 51 and a position corresponding to the gripping part 42 located on the upstream side of the conveyance path (first delivery position HP1). Move back and forth with. Here, the supply moving mechanism 56 is movable in a plane orthogonal to the extending direction of the covered electric wire 12. Specifically, the supply movement mechanism 56 includes a horizontal movement mechanism 57 and an elevation movement mechanism 58.

  The horizontal movement mechanism 57 is configured by an air cylinder, a hydraulic cylinder, a linear motor, or the like. The horizontal movement mechanism 57 moves the supply chuck 51 in the direction in which the plurality of covered electric wires 12 are arranged.

  The raising / lowering moving mechanism 58 is configured by an air cylinder, a hydraulic cylinder, a linear motor, or the like. The raising / lowering moving mechanism 58 moves the supply chuck 51 in a direction orthogonal to the direction in which the plurality of covered electric wires 12 are arranged and orthogonal to the extending direction of the covered electric wires 12.

<Electric wire processing unit 60>
The electric wire processing unit 60 processes the end 12 a of the covered electric wire 12 sent by the electric wire transport unit 40. The electric wire processing unit 60 includes a crimping unit 70. Furthermore, here, the wire processing unit 60 includes a wire color check unit 61, a tip cut unit 62, a rubber plug insertion unit 63, a skin peeling unit 64, a skin peeling check unit 65, and a terminal check unit 67. . These are line color check part 61, tip cut part 62, rubber plug insertion part 63, skin peeling part 64, skin peeling check part 65, pressure bonding part 70, from upstream to downstream along the transport path. They are arranged in the order of the terminal check section 67. The skin peeling check unit 65 and the terminal check unit 67 are components of an inspection unit that inspects whether the processed covered electric wire 12 is a non-defective product.

  The wire color check unit 61 can determine the color of the covering of the covered electric wire 12. The line color check unit 61 can be configured by a color sensor, for example. The determination result of the line color check unit 61 is sent to the control unit 120. The control unit 120 associates the covered electric wire 12 supplied based on the determination result with the gripping unit 42. On the other hand, a table in which the color of the insulating coating 14 of the covered electric wire 12 and the crimping mechanism 71 are associated with each other is given to the control unit 120 in advance. And the control part 120 matches the holding | grip part 42 and the crimping | compression-bonding mechanism 71 based on the positional relationship of the corresponding covered electric wire 12 and the holding | grip part 42, and the said table. Based on this, the control unit 120 issues a crimping command to the crimping mechanism 71 to which the corresponding gripping unit 42 is conveyed.

  The front end cut portion 62 cuts the front end of the covered electric wire 12 extending to the front end of the holding portion 33 and trims the covered electric wire 12 so that the allowance from the holding portion 33 becomes a predetermined length. Thereby, the length of peeling can be stabilized and the quality at the time of crimping | compression-bonding can be stabilized. Further, as described above, in the electric wire setting unit 30, the extension amount is set in a state where there is variation within the range between the first threshold value and the second threshold value, and is sent to the gripping unit 42 as it is. The tip cut portion 62 reduces this variation. Thereby, the possibility of making a processing error with respect to the covered electric wire 12 held by the holding portion 33 in a later process is reduced. In addition, the predetermined length in the front-end | tip cut part 62 may be the same as the predetermined length detected by the allowance detection part 37, and may be shorter than this.

  The rubber plug insertion portion 63 is a unit for inserting a rubber plug into the end 12 a of the covered electric wire 12. The rubber plug insertion portion 63 includes a rubber plug holding mechanism that holds the outer periphery of the rubber plug in a state where the axis of the rubber plug and the axis of the covered electric wire 12 coincide with each other, and a rubber plug holding mechanism that is attached to the covered electric wire 12. It is possible to employ a known rubber plug insertion device including a reciprocating mechanism for reciprocally moving. In general, whether or not the rubber plug insertion portion 63 inserts a rubber plug is preset for each covered electric wire 12. Therefore, similarly to the crimping command, the control unit 120 determines which gripping part 42 is to insert the rubber plug into the covered electric wire 12 based on the determination result of the wire color check unit 61, and the rubber plug insertion part 63. It is possible to instruct.

  The skinned portion 64 is a unit that performs processing to peel the end 12a of the covered electric wire 12 and expose the conductor core wire 13 to the end 12a. As the skinning portion 64, for example, the tip portions of the pair of skinning blades are moved close enough to bite only into the insulating coating 14 of the electric wire 12, and in this state, the pair of skinning blades are connected to the end portions 12 a of the electric wires 12. By moving to the side, the insulation coating 14 is peeled off. For example, the diameter of the covered electric wire 12 included in the cable 10 may be remarkably different, and it may be necessary to set the distance between a pair of close peeling blades for each electric wire. In this case, it is conceivable that the control unit 120 determines the interval between the pair of skinning blades for each gripping part 42 based on the determination result of the line color check part 61 as in the case of the crimping command and instructs the skinning part 64.

  The skin peeling check unit 65 is a unit that checks the state of the end 12 a of the covered electric wire 12 that has been skinned by the skin peeling unit 64. The skin peeling check unit 65 includes, for example, an imaging unit that can image the end 12a of the covered electric wire 12 and a skinning state inspection unit that inspects the skinning state from the imaging data. The check result of the skin peeling check unit 65 is sent to the control unit 120. In response to this, for example, the control unit 120 may issue a command to the crimping unit 70 so as not to crimp the terminal 17 to the covered electric wire 12 that is determined to be defective by the skinning check unit 65. Further, for example, the control unit 120 may issue a command to the electric wire discharging unit 80 so as to discharge the covered electric wire 12 determined to be defective by the skinning check unit 65 to a defective product holder 94 described later.

  The crimping part 70 has a plurality of (here, four) crimping mechanisms 71. It is preferable that the crimping portion 70 includes three or more crimping mechanisms 71. The crimping mechanism 71 crimps the terminal 17 to the end 12 a of the covered electric wire 12. The plurality of crimping mechanisms 71 are arranged along the transport path. Here, the crimping mechanism 71 will be described with reference to FIGS. 5 to 7 are schematic side sectional views showing the crimping mechanism 71. FIG. FIG. 5 shows a state immediately after the covered electric wire 12 to be processed is sent to the crimping mechanism 71. FIG. 6 shows a state where the lower mold 73 is raised. FIG. 7 shows a state where the terminal 17 is crimped.

  The crimping mechanism 71 includes an upper mold 72 (also referred to as a crimper) and a lower mold 73 (also referred to as an anvil) that sandwich and crimp the terminal 17, and an elevating unit 75 that raises and lowers at least the lower mold 73. Here, the elevating unit 75 includes a first elevating unit 76 that moves the upper die 72 and the lower die 73 up and down, and a second elevating unit 77 that moves the upper die 72 up and down. Each raising / lowering part 75 is comprised by a cylinder or a motor.

  More specifically, at the time of conveyance, as shown in FIG. 5, the tip of the end group 12 g is positioned between the upper mold 72 and the lower mold 73 and is placed on the upper mold 72 and the lower mold 73. The contacted terminal 17 is passed through without contact. Then, when the end 12a to be processed is sent to the crimping mechanism 71 in the end group 12g, the elevating part 75 moves the upper mold 72 and the lower mold 73 upward, and as shown in FIG. The end portion 12 a is inserted between the pair of crimping pieces 18 a of the barrel portion 18 of the terminal 17 placed on the mold 73. In this state, the elevating unit 75 moves the upper die 72 downward, so that the terminal 17 and the covered wire 12 are sandwiched between the upper die 72 and the lower die 73 as shown in FIG. Crimped.

  In the example shown in FIGS. 5 to 7, the terminal 17 is supplied in the form of a continuous terminal connected to the strip-shaped carrier 19, and the carrier separating section 78 that separates the carrier 19 and the terminal 17 from the crimping mechanism 71. Is included, but this is not required.

  The terminal check unit 67 checks the state of the terminal 17 crimped by the crimping unit 70. Here, the terminal check unit 67 includes a height check unit 68 that checks the crimping height of the terminal 17 and an image inspection unit 69 that inspects the protrusion of the core wire and the like with an image. Such a height check unit 68 is configured by, for example, a linear gauge. Further, such an image inspection unit 69 includes an imaging unit that can image the crimped terminal 17 and a determination unit that determines a protrusion of a core wire or the like from imaging data obtained by the imaging unit. The check result obtained by the terminal check unit 67 is sent to the control unit 120. In response to this, the control unit 120 may, for example, issue a command to the wire discharge unit 80 so that the covered wire 12 determined to be defective by the terminal check unit 67 is discharged to the defective product holder 94.

<Wire discharge part>
FIGS. 8 and 9 are schematic front views showing the wire discharge portion 80, the holder 90, and the wire push-in portion 100. The electric wire discharge unit 80 discharges the end group 12g held by the holding unit 42 in a lump. The electric wire discharge unit 80 includes a discharge chuck 81 and a discharge movement mechanism 85.

  The discharge chuck 81 is provided such that each end 12a of the end group 12g can be chucked. The discharge chuck 81 can have the same configuration as the supply chuck 51.

  The discharge movement mechanism 85 reciprocates the discharge chuck 81 between a position (second delivery position HP2) corresponding to the grip portion 42 located on the downstream side of the transport path and the wire discharge position DP. The discharge movement mechanism 85 can have the same configuration as the supply movement mechanism 56.

  Furthermore, here, the electric wire processing apparatus 20 further includes a holder 90 and an electric wire pushing portion 100.

<Holder>
The holder 90 is provided at the wire discharge position DP. The holder 90 stores the end group 12g transferred from the electric wire discharge unit 80. The holder 90 includes a non-defective product holder 92 that stores non-defective products, and a defective product holder 94 that stores defective products. The non-defective product holder 92 and the defective product holder 94 are formed in the same shape. Specifically, each holder 90 is formed in a box shape, and is formed with a groove 91h that opens on the upper edge side and extends in the vertical direction. The end group 12g is transferred to the upper edge side of each groove by the wire discharger 80.

<Wire pushing part>
The electric wire pushing part 100 is formed so that the covered electric wire 12 transferred to the upper edge side of the groove 91h can be pushed downward. The electric wire pushing portion 100 includes a pushing plate portion 102 and a pushing plate portion moving mechanism 106. The pushing plate portion 102 is formed in a rectangular flat plate shape, and the lower surface 103 that contacts the covered electric wire 12 is formed in a curved surface shape. More specifically, the lower surface 103 is formed in a front view wave shape in which a convex surface 103a and a concave surface 103b are continuous. And it is provided so that the covered electric wire 12 may be pushed in by the concave surface 103b. The pushing plate portion moving mechanism 106 includes an air cylinder, a hydraulic cylinder, a linear motor, or the like. The pushing plate portion moving mechanism 106 is provided so that the pushing plate portion 102 can reciprocate between a pushing position and a retracted position.

<Control unit>
The control unit 120 will be described with reference to FIG. FIG. 10 is a block diagram showing the control unit 120.

  The control unit 120 is connected to the wire setting unit 30, the wire conveyance unit 40, the wire supply unit 50, the wire processing unit 60, the wire discharge unit 80, and the wire pushing unit 100. In addition, the results obtained by the holding detection unit 36, the allowance detection unit 37, the inspection unit, and the line color check unit 61 are given to the control unit 120. Thereby, the control part 120 performs operation control of each part based on each result.

  The control unit 120 is configured by a general computer in which a CPU 122, a ROM 123, a RAM 124, an external storage device 125, and the like are interconnected via a bus line 121. The ROM 123 stores basic programs and the like, and the RAM 124 is used as a work area when the CPU 122 performs processing according to a predetermined procedure. The external storage device 125 is configured by a nonvolatile storage device such as a flash memory or a hard disk device. The external storage device 125 stores an OS (operation system) 126 and a machining program 127 including a processing program 127a for processing electric wires. As will be described in detail later, the CPU 122 as the main control unit 120 performs arithmetic processing according to the procedure described in the machining program 127, thereby controlling the operation of each unit.

  In the control unit 120, the external signal input interface 128 and the input / output interface 129 are also connected to the bus line 121. And the signal which transmits the result of the holding | maintenance detection part 36, the departure detection part 37, the test | inspection part, and the wire color check part 61 is input into this control part 120 through the external signal input interface 128, and is provided to an electric wire process. . In addition, a control signal from the control unit 120 is given to the wire setting unit 30, the wire transfer unit 40, the wire supply unit 50, the wire processing unit 60, the wire discharge unit 80, and the wire pushing unit 100 through the input / output interface 129. The electric wire set unit 30, the electric wire transport unit 40, the electric wire supply unit 50, the electric wire processing unit 60, the electric wire discharge unit 80, and the electric wire pushing unit 100 are driven and controlled.

  The control unit 120 is connected to an input unit 130 that includes various switches, a touch panel, and the like, and can receive various instructions to the control unit 120. For example, here, a start switch for starting electric wire supply is connected to the control unit 120. And a processing program is started with respect to the end group 12g set to the electric wire set part 30 by an operator turning ON a start switch in the state in which the end group 12g was set to the electric wire set part 30. .

  Here, the control unit 120 serves as a crimping control unit, a delivery control unit as a delivery state determination unit, and a discharge control unit as a discharge holder instruction unit.

  The crimping control unit executes a use crimping mechanism determination process for determining the crimping mechanism 71 to be used among the plurality of crimping mechanisms 71 with respect to the end portions 12 a of the plurality of covered electric wires 12. For example, the used crimping mechanism determination process may be a process of determining the crimping mechanism 71 to be used based on the determination result of the line color check unit 61. Further, for example, the used crimping mechanism determination process may be a process of determining the crimping mechanism 71 to be used based on the position where the covered electric wire 12 is set. This will be described in detail later.

  The delivery control unit determines whether or not the end group 12g set in the holding unit 33 can be delivered. When the delivery control unit detects that the covered electric wire 12 is held by the holding unit 33 and detects that the output of the covered electric wire 12 detected by the holding detection unit 36 is a predetermined length or more, the delivery control unit It is determined that the covered wire 12 can be delivered from the unit 30 to the wire supply unit 50. The delivery control unit detects that the covered electric wire 12 is held by the holding unit 33 or detects that the covered electric wire 12 is held by the holding unit 33 and detects it by the holding detection unit 36. When it is not detected that the allowance of the covered wire 12 is longer than a predetermined length, it is determined that the covered wire 12 cannot be delivered from the wire setting unit 30 to the wire supply unit 50.

  The discharge control unit instructs the holder 90 for discharging the covered electric wire 12 to the electric wire discharge unit 80 according to the inspection result of the inspection unit.

  Moreover, the control part 120 controls each part of the electric wire supply part 50 and the electric wire process part 60, the drive part 47, and the electric wire discharge part 80 as follows, for example. That is, the control unit 120 determines whether or not at least one of processing, supply, and discharge by any processing device is performed on the end group 12g every time the belt 46 is fed by one pitch. When it is determined that any of the processes is performed, a process start command is issued to each unit that performs the process. Thereafter, when it is determined that all the processes have been completed in response to processing completion signals from the respective units, a command is sent to the driving unit 47 to send the next one pitch. In addition, when it is determined that it is not performed, a command is sent to the drive unit 47 to send the next one pitch immediately. Therefore, by performing a plurality of processes as much as possible, the time for one cycle is shortened as compared with the case where each process is performed separately.

  Note that some or all of the functions performed by the control unit 120 may be realized by hardware using a dedicated logic circuit or the like.

<Process flow>
Next, the flow of processing for one end group 12g will be described based on the flow of processing in the control unit 120. FIG. 11 is a flowchart showing the flow of processing in the control unit 120.

  First, in step S01, it is confirmed that the end group 12g is set in the electric wire setting unit 30. When the control unit 120 confirms that the end group 12g is set in the electric wire setting unit 30, the process proceeds to the next step S02. In next step S <b> 02, the control unit 120 checks the leading edge of the covered electric wire 12. A more specific processing flow of steps S01 and S02 is shown in FIG.

  That is, in step S <b> 21, the control unit 120 determines whether there is an end 12 a of the covered electric wire 12 held by the holding unit 33. For example, the end 12 a of the covered electric wire 12 is set on the electric wire setting unit 30 by an operator. When the end 12 a of the covered electric wire 12 is set in the electric wire setting unit 30, the holding detection unit 36 detects that the end 12 a of the covered electric wire 12 is set in the holding unit 33. Here, for each holding claw 34, the holding detection unit 36 detects the setting of the end 12 a and gives this signal to the control unit 120. When the control unit 120 receives the detection result of the holding detection unit 36 and determines that there is the end 12a held by the holding unit 33 from the received detection result, the process proceeds to step S22. If it is determined that there is no held end 12a, the process proceeds to step S24.

  In step S22, the length of the margin of the held end 12a is determined. For example, the control unit 120 issues a command to detect the allowance to the allowance detecting unit 37 disposed near the holding claws 34 that are determined to have the held end 12a. In response to this, the allowance detection unit 37 detects the allowance, and gives this signal to the control unit 120. At this time, if a positive result is obtained, the control unit 120 proceeds to step S23 if it determines that the allowance is greater than or equal to the predetermined length. On the other hand, if a negative result is obtained, the control unit 120 proceeds to step S24 if it determines that the allowance is not longer than the predetermined length.

  In step S23, the control unit 120 determines that the end group 12g can be delivered. In this state, when the worker turns on the start switch, delivery of the end group 12g is started.

  In step S24, the control unit 120 determines that the end group 12g cannot be delivered. In this state, even when the operator turns on the start switch, the delivery of the end group 12g is not started. After step S24, the process returns to step S01.

  If it is determined in step S23 that the end group 12g can be delivered, the process proceeds to step S03.

  In step S03, the control unit 120 confirms whether the worker has turned on the start switch. When it is confirmed that the operator has turned on the start switch, the control unit 120 proceeds to step S04.

  In step S04, electric wire supply and conveyance are started. For example, when it is confirmed that the operator has turned on the start switch, the control unit 120 first instructs the drive unit 47 to stop. In response to this, when the drive unit 47 stops, the control unit 120 issues a command to the up-and-down movement mechanism 39 to raise the holding unit 33 and causes the supply movement mechanism 56 to move the supply chuck 51 to the set position SP. Issue a command. In response to this, when the raising / lowering moving mechanism 39 raises the holding unit 33 and the supply moving mechanism 56 moves the supply chuck 51 to the set position SP, the control unit 120 issues a command to close the supply chuck 51. Then, the holding unit 33 is instructed to open. In response to this, the supply chuck 51 closes and the holding portion 33 opens, so that the supply chuck 51 chucks the end group 12g at a time.

  Subsequently, the control unit 120 issues a command to the supply movement mechanism 56 so as to move the supply chuck 51 to the first delivery position HP1, and also issues a command to the state change operation execution unit 48 so as to open the gripping unit 41. In response to this, the supply moving mechanism 56 moves the supply chuck 51 to the delivery position HP1, and when the state change operation execution unit 48 opens the gripping unit 41, the control unit 120 issues a command to open the supply chuck 51. At the same time, it issues a command to the state change operation execution unit 48 to close the gripping unit 41. In response to this, the supply chuck 51 is opened and the state changing operation execution unit 48 closes the gripping unit 41, so that the gripping unit 41 grips the covered electric wire 12. Note that the control unit 120 issues a command to the lifting and lowering movement mechanism 39 to lower the holding unit 33 as appropriate when the transfer of the end group 12g from the holding unit 33 to the supply chuck 51 is completed. In response to this, the lifting / lowering moving mechanism 39 lowers the holding portion 33, so that the operator can set the next end group 12 g on the holding portion 33.

  Subsequently, the control unit 120 issues a command to the supply movement mechanism 56 so as to retract the supply chuck 51 and also issues a command to the drive unit 47 to resume driving. In response to this, the supply moving mechanism 56 retreats the supply chuck 51 to a position where it does not interfere with the grip portion 42 or the end group 12g gripped by the grip portion 42, and the drive portion 47 resumes driving, thereby conveying. The conveyance of the end group 12g by the unit 45 is started. When the conveyance of the end group 12g by the conveyance unit 45 is started, the process proceeds to step S05. Here, it is determined whether or not the conveyance of the end group 12g by the conveyance unit 45 is performed for each pitch as described above. In the following, in steps S05 to S12, description will be made assuming that the end group 12g sent for each pitch by the transport unit 45 has been transported to a corresponding position by the processing apparatus.

  In the next step S05, a line color check is performed. For example, the control unit 120 instructs the line color check unit 61 to check the line color with respect to the sent end group 12g. In response to this, the line color check unit 61 sequentially checks the color of the insulating coating 14 at each end 12a of the end group 12g with a color sensor. The signal of the check result of the line color check unit 61 is given to the control unit 120. From this signal, the control unit 120 associates the position of the grip portion 42 with the type of the end portion 12a gripped by the grip portion 42. When this is completed, the process proceeds to step S06.

  In the next step S06, the tip is cut. For example, the control unit 120 issues a command to the tip cut unit 62 so as to cut the tip of each end 12a of the end group 12g that has been sent. In response to this, when the leading end cutting unit 62 cuts the leading end of the end portion 12a, the process proceeds to the next step S07.

  In step S07, a rubber plug is inserted. For example, the control unit 120 is provided with a table in which the color of the insulating coating 14 at the end 12a and the presence / absence of insertion of a rubber plug are associated in advance. The control unit 120 determines the gripping unit 42 that performs the rubber plug insertion process from the table and the association between the gripping unit 42 and the end 12a obtained in step S05. And if the said grip part 42 is sent, the control part 120 will give a command to the rubber plug insertion part 63 so that a rubber plug may be inserted with respect to the edge part 12a which the said grip part 42 grips. In response to this, when the rubber plug insertion portion 63 inserts the rubber plug into the end portion 12a, the process proceeds to the next step S08.

  In step S08, skinning is performed. For example, the control unit 120 issues a command to the skinning unit 64 so as to skin the tips of the end portions 12a of the end group 12g that has been sent. In response, when the skinning part 64 skins the tip of the end part 12a, the process proceeds to the next step S09. In addition, when it is necessary to change the space | interval of a stripping blade according to the kind of the covered electric wire 12, the table which matched the color 14 of the insulation coating of the covered electric wire 12 with the space | interval of a stripping blade is previously given to the control part 120. . The control part 120 determines the space | interval of a peeling blade for every holding | grip part 42 from the said table and the matching of the holding | grip part 42 and the covered electric wire 12 obtained by step S05. Then, the control unit 120 issues a command to the skinning unit 64 so that the skin is peeled at the determined interval with respect to the end 12a gripped by the gripping unit 42.

  In step S09, a skin peeling check is performed. For example, the control unit 120 issues a command to the skin peeling check unit 65 so as to sequentially perform the skin peeling check on each end 12a of the sent end group 12g. In response to this, the skin peeling check unit 65 checks the state of skinning of the end portion 12a. A signal of the check result of the skin peeling check unit 65 is given to the control unit 120. From this signal, the control unit 120 determines whether or not to perform crimping on the end 12a and determines the holder 90 that discharges the covered electric wire 12. When the skin peeling check unit 65 checks the state of skinning of the end portion 12a, the process proceeds to step S10.

  In step S10, pressure bonding is performed. For example, as described above, the controller 120 is provided with a table in which the color of the insulating coating 14 of the end 12a and the crimping mechanism 71 are associated with each other in advance. The control unit 120 crimps the terminal 17 to the end 12a gripped by which gripping part 42 by which crimping mechanism 71 based on the table and the association between the gripping part 42 and the end 12a obtained in step S05. Decide what to do. Then, when the target gripping portion 42 is sent to each of the plurality of crimping mechanisms 71, the control unit 120 issues a command to crimp the end portion 12 a gripped by the gripping portion 42. In response to this, each crimping mechanism 71 for which a command has been issued crimps the terminal 17 to the end 12a gripped by the target gripper 42, and then proceeds to step S11.

  In step S11, a terminal check is performed. Specifically, the control unit 120 issues a command to the height check unit 68 and the image inspection unit 69 so as to check the state of the terminal 17 with respect to each end 12a of the end group 12g that has been sent. In response to this, the height check unit 68 and the image inspection unit 69 check the state of each terminal 17 of the end group 12g. Signals of check results from the height check unit 68 and the image inspection unit 69 are given to the control unit 120. For example, the control unit 120 determines the holder 90 that discharges the end group 12g from this signal. When the state of each terminal 17 of the end group 12g is checked, the process proceeds to step S12.

  In step S12, the end group 12g is discharged. For example, when the end group 12g is sent to the second delivery position HP2 by the transport unit 45, the control unit 120 first instructs the drive unit 47 to stop. In response to this, when the drive unit 47 stops, the control unit 120 issues a command to the discharge movement mechanism 85 to move the discharge chuck 81 to the second delivery position HP2. For example, the initial position of the discharge chuck 81 is set above the second delivery position HP2. In this case, a command is issued to the discharge moving mechanism 85 to lower the discharge chuck 81. In response to this, when the discharge moving mechanism 85 moves the discharge chuck 81 to the second delivery position HP2, the control unit 120 issues a command to close the discharge chuck 81 and changes the state to open the gripping unit 42. A command is issued to the operation execution unit 48. In response to this, the discharge chuck 81 is closed, and the state changing operation execution unit 48 opens the gripping unit 42, whereby the discharge chuck 81 chucks the covered electric wire 12.

  Subsequently, the control unit 120 issues a command to the discharge movement mechanism 85 so as to move the discharge chuck 81 to the discharge position.

  Here, the discharge position is determined based on a determination result obtained by receiving the inspection result of the inspection unit and determining whether the control unit 120 is a non-defective product or a defective product. A more specific flow of the discharge position determination process is shown in FIG.

  That is, in step S31, the control unit 120 receives the inspection result of the inspection unit. Here, the check result of the skin peeling check unit 65 is received in step S09, and the check result of the terminal check unit 67 is received in step S11. If the inspection result of the inspection unit is received, the process proceeds to step S32.

  In next step S32, the control unit 120 determines whether the end group 12g is a non-defective product from the inspection result. If it is determined to be a non-defective product, the process proceeds to step S33, and if it is determined to be a defective product, the process proceeds to step S34.

  In step S <b> 33, the control unit 120 issues a command to discharge the end group 12 g determined to be non-defective to the non-defective holder 92. For example, the control unit 120 instructs the discharge movement mechanism 85 to move the discharge chuck 81 that chucks the end group 12g to a position corresponding to the non-defective holder 92.

  On the other hand, in step S <b> 34, the control unit 120 issues a command to discharge the end group 12 g determined to be defective to the defective product holder 94. For example, the control unit 120 instructs the discharge movement mechanism 85 to move the discharge chuck 81 that chucks the end group 12g to a position corresponding to the defective product holder 94.

  By passing through either step S33 or step S34, the discharge movement mechanism 85 moves the discharge chuck 81 to either the position corresponding to the non-defective product holder 92 or the position corresponding to the defective product holder 94. It will be in the state that was let. As described above, when the discharge moving mechanism 85 moves the discharge chuck 81 to the discharge position, the control unit 120 issues a command to open the discharge chuck 81. In response to this, the discharge chuck 81 is opened, so that the covered electric wire 12 is transferred to the upper edge of the holder 90.

  Subsequently, the control unit 120 issues a command to the discharge movement mechanism 85 so as to retract the discharge chuck 81 and also issues a command to the push plate part movement mechanism 106 so as to lower the push plate part 102. In response to this, the discharge moving mechanism 85 retracts the discharge chuck 81 and the pushing plate portion moving mechanism 106 lowers the pushing plate portion 102, so that the covered electric wire 12 is pushed below the holder 90, and the covered electric wire 12. Is completely discharged.

  From the above, one cycle for the end group 12g set simultaneously in the electric wire set unit 30 is completed. In addition, 1 cycle with respect to the some end group 12g set to the electric wire set part 30 at a respectively different timing may be performed in parallel.

<Modified example of used crimping mechanism determination process>
Up to this point, it has been described that the crimping mechanism 71 to be used for crimping the terminal 17 to each end portion 12a among the plurality of crimping mechanisms 71 is determined using the check result of the line color check unit 61. Is not required. For example, the crimping mechanism 71 used for crimping the terminal 17 to each end 12a among the plurality of crimping mechanisms 71 may be determined depending on the set position on the electric wire setting unit 30.

  In FIG. 14, the process of determining the crimping mechanism 71 to be used using the check result of the wire color check unit 61 and the process of determining the crimping mechanism 71 to be used depending on the set position on the wire set unit 30 are used together. The processing flow is shown.

  That is, in step S41, the control unit 120 determines whether there is a check instruction from the line color check unit 61. The check instruction is given to the control unit 120 by the operator through the input unit 130. That is, here, it is determined whether or not the crimping mechanism 71 to be used is determined using the check result of the line color check unit 61. If there is a check instruction, the process proceeds to step S42; otherwise, the process proceeds to step S44.

  In step S42, the check result of the line color check unit 61 is received. For example, the control unit 120 checks the line color when the gripping unit 42 that grips the end 12a is sent, and issues a command to the line color check unit 61 to return the check result. If a check result is received, it will progress to following step S43.

  In the next step S43, the crimping mechanism 71 to be used is determined from the check result of the line color check unit 61. As described above, the table of the line color of the end portion 12a and the crimping mechanism 71 to be used is given to the control unit 120 in advance. Further, from the check result, the grip portion 42 and the line color of the end portion 12a gripped by the grip portion 42 are associated with each other. Accordingly, the end portion 12a gripped by the grip portion 42 is associated with the crimping mechanism 71 used for crimping the terminal 17 to the end portion 12a. Thereafter, the process proceeds to step S45.

  On the other hand, in step S44, a table in which the position of the set end group 12g and the crimping mechanism 71 used for crimping the terminal 17 to the end 12a at the position is associated with the control unit 120 in advance is given. It is done. In this case, the operator sets each end 12a to the designated holding claw 34. The end group 12g set in the electric wire set unit 30 is sent to the grip unit 42 while maintaining the positional relationship. Therefore, according to the table, the control unit 120 can associate the end portion 12a gripped by the gripping portion 42 with the crimping mechanism 71 used for crimping the terminal 17 to the end portion 12a. Thereafter, the process proceeds to step S45.

  The crimping mechanism 71 to be used is determined through either step S43 or step S44. In step S <b> 45, when the target gripping portion 42 is sent to each of the plurality of crimping mechanisms 71, the control unit 120 issues a command to crimp the end 12 a gripped by the gripping portion 42. In response to this, each crimping mechanism 71 for which a command has been issued crimps the terminal 17 to the end 12a gripped by the target gripping portion 42, whereby the terminal 17 suitable for each end 12a is crimped. .

<Other cable set examples>
15 to 18 are explanatory views showing other examples of the cable 10 set. In the present wire processing apparatus 20, in addition to the cable 10 including the three covered wires 12, for example, the cable 110 including the two covered wires 12 and the cable 210 including the four to six covered wires 12, 310 can be the main processing target. In the case of the cables 110 and 10 including two or three covered electric wires 12, all the end portions 12a at both ends can be processed in one cycle. In the case of the cables 210 and 310 including four to six covered electric wires 12, all the end portions 12a at both ends can be processed in two cycles. Of course, a cable including one covered wire 12 or a cable including seven or more wires can be processed using the wire processing apparatus 20.

  For example, in the case of the cable 110 including two covered electric wires 12, as shown in FIG. 15, the two end portions 12 a on the one end portion 110 a side are set on the two holding claws 34, and the other two holding claws 34 are attached. Two end portions 12a on the other end portion 110b side are set. At this time, as shown in FIG. 15, the two end portions 12 a are preferably held by two adjacent holding claws 34 on the one end portion 110 a side and the other end portion 110 b side. In the example shown in FIG. 15, the one end 110 a side and the other end 110 b side are separated by one holding claw 34, but may be separated by two, or may not be separated.

  Further, for example, in the case of the cable 210 including four or five covered electric wires 12, as shown in FIG. 16, the four or five holding claws 34 have four or five on the one end 210 a side. One end 12a may be set. At this time, as shown in FIG. 16, four or five end portions 12 a on one end side may be set on four or five holding claws 34 adjacent to each other.

  Further, for example, in the case of the cable 310 including six covered electric wires 12, as shown in FIG. 17, the six end portions 12 a on the one end portion 310 a side are set on the six holding claws 34 of the holding portion 33.

  Here, since the holding claws 34 are six pairs, when the number of the covered electric wires 12 included in one cable is four or more, both ends are not processed in one cycle. In this case, while the one end portion side is being processed, the electric wire processing apparatus 20 is moved in a state where the other end portion hangs down. It is conceivable that the other end side is processed by the electric wire processing apparatus 20 after being set and re-set in the electric wire setting unit 30 after the one end side is processed and discharged.

  Up to this point, it has been described that one end of one cable is processed at the same time in the same cycle, but this is not essential. The end 12a of the covered electric wire 12 on one end side of one cable may be processed by being divided into different cycles. In this case, for example, as shown in FIG. 18, it is conceivable that a part of the end on the one end side and a part of the end on the other end side are set in the electric wire setting unit 30 in the same cycle. . In FIG. 18, in the cable 310 including the six covered electric wires 12, the three end portions 12 a on the one end portion 310 a side and the three end portions 12 a on the other end portion 310 b side are set in the holding portion 33. . At this time, the three end portions 12a on the one end portion 310a side and the three end portions 12a on the other end portion 310b side may or may not include the end portion 12a of the same covered wire 12. May be. For example, when the length at which the sheath 16 at the end of the cable can be peeled off is short, the crotch of the covered electric wire at one end cannot be expanded so much that it is difficult to set all the ends at one end at a time There is. In this case, a setting method as shown in FIG. 18 is preferable.

  According to the electric wire processing apparatus 20 configured as described above, after the electric wire is set by the operator, the electric wire processing apparatus 20 that takes in, processes, and discharges the used crimping mechanism determination process is executed and executed. By issuing a crimping command based on the result, different terminals 17 can be appropriately crimped to each end 12a of the covered electric wire 12 included in one cable 10. Thereby, another terminal 17 can be crimped | bonded with respect to the some covered electric wire 12 contained in one cable 10 with one set with respect to more types of cables 10. FIG.

  Further, by providing the wire color check unit 61, an appropriate crimping mechanism 71 is selected regardless of the set location of the electric wire. Thereby, an operator can select the set location of an electric wire freely.

  Moreover, when the set location of an electric wire and the crimping | compression-bonding mechanism 71 to be used are matched, the appropriate terminal 17 can be crimped | bonded with respect to the electric wire set to the predetermined set location.

  Further, even when the cable 10 includes three or more covered electric wires 12 and different terminals 17 are crimped, at least one end side can be processed by the electric wire processing apparatus 20 in one set.

  In the case of the cable 10, the amount of the sheath 16 that can be peeled off is limited due to the characteristics, and if the number of the covered electric wires 12 included in the cable 10 is large, it is difficult to divide and hold each end 12 a. Even in this case, the width of the gripping portion 42 can be made as small as possible, and therefore, as many coated wires 12 as possible can be gripped by the gripping portion 42 even when the number of the covered wires 12 included in the cable 10 is large.

  In addition, it is desirable that the upper mold 72 and the lower mold 73 of the crimping mechanism 71 are located at positions apart from each other with respect to the covered electric wire 12 to be transported when not crimped. On the other hand, the lower mold 73 is also desired to support the covered electric wire 12 from below during crimping. At this time, the lower mold 73 is lowered when it is not crimped so that it does not interfere with the covered electric wire 12 being conveyed, and the lower mold 73 is raised during the crimping so that the covered electric wire 12 can be supported from below. For this reason, the said crimping | compression-bonding mechanism 71 becomes a form suitable for the crimping | compression-bonding in the aspect in which the covered electric wire 12 passes between the upper mold | type 72 and the lower mold | type 73. FIG.

  Further, depending on the number of the covered electric wires 12 included in the cable 10, only one end side of the cable 10 may be set on the electric wire setting unit 30. In this case, the cable 10 is transported in a state in which the other end hangs down, that is, in a state in which the amount of sag is greater than when both ends are set in the electric wire setting unit 30. Even in this case, since the electric wire setting unit 30 includes the up-and-down moving mechanism 39, the electric holding unit 33 can be raised to a high position after the electric wire is set in the holding unit 33 at a low position where an operator can easily work. And the cable 10 which hangs down by conveying the cable 10 in this high position can be conveyed, without making it contact a floor surface.

  In addition, by providing the allowance detection unit 37, the electric wire is not supplied when the allowance is insufficient. Thereby, generation | occurrence | production of the crimping | compression-bonding defect etc. can be suppressed.

  Moreover, an operator can receive the cable 10 discharged | emitted by providing the holder 90 for every set number.

  Further, the provision of the wire push-in portion 100 is suitable for storing a plurality of covered wires 12.

  In addition, since the non-defective product and the defective product are sorted and discharged, it is not necessary for the operator to make a journal and it is easy to move to a subsequent process.

{Modification}
In the embodiment, the electric wire discharge unit 80 is described as being provided, but this is not essential. For example, there may be a case where the operator does not provide the electric wire discharge unit 80 by receiving the end group 12g from the transport unit 45. Moreover, even when the electric wire discharge part 80 is provided, it is not essential that the good product and the defective product are sorted and discharged.

  In the embodiment, each part of the electric wire processing unit 60 other than the crimping unit 70 may be omitted as appropriate.

  In addition, the description has been made so far as another terminal 17 is crimped to the plurality of end portions 12a. However, it is needless to say that the same terminal 17 may be crimped to the plurality of end portions 12a.

  In addition, each structure demonstrated by 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.
