Description

  The present invention relates to an electric wire processing system, and more particularly to an electric wire processing system for manufacturing a wire harness using various types of electric wires.

  As a terminal processing device, there is known a terminal crimping device that removes a covering material from an end portion of an electric wire, crimps a terminal to the end portion, and cuts the electric wire into a predetermined length. Specifically, as shown in FIG. 21, a terminal crimping device 501 includes a wire crimping device 502, a first crimping mechanism 503 for crimping a terminal to the leading end side and the trailing end side of the wire L, and a second crimping device. A mechanism 504, a cutting mechanism 505 for cutting the electric wire L and removing the covering material at the end of the electric wire L, an electric wire feeding mechanism 506 for feeding the tip end side of the electric wire L to the first crimping mechanism 503, and the electric wire after cutting A chuck mechanism (not shown) that holds L and feeds the rear end side of the electric wire L to the second crimping mechanism 504, and a discharge device (not shown) that discharges the electric wire L after crimping the terminal T to the outside. Yes.

  The first crimping mechanism 503 and the second crimping mechanism 504 have the same basic configuration, and an applicator 509 for crimping a terminal is attached to the frame member 510. That is, a notch 511 is formed on the side surface of the frame member 510, and the applicator 509 is attached in the notch 511. Specifically, the upper unit 512 of the applicator 509 is attached above the notch 511, and the lower unit 513 of the applicator 509 is attached below the notch 511.

  The electric wire feeding mechanism 506 includes an electric wire take-in guide 557, an encoder 558 for measuring the length of the electric wire L, a pair of rollers 559 and the like that are spaced apart from each other by a predetermined distance. (See Patent Document 1).

  On the other hand, as a method for supplying electric wires to the terminal crimping device 501, for example, a plurality of electric wire drums wound with different electric wires are provided, and electric wires to be processed from the plural electric wire drums are manually applied to the terminal crimping device 501. Supplying is generally done. That is, it is a method of setting the tip of the electric wire wound around the electric wire drum to the electric wire feeding mechanism 506 through the electric wire scraping device 502 of the terminal crimping device 501, and thereafter, a pair of wires provided with the electric wire feeding mechanism 506. The electric wire can be fed out from the electric wire drum by the power (pulling operation) of the roller 559.

  By the way, many covered electric wires for wiring are used in electrical products. These covered electric wires are composed of a core wire formed of copper or the like and a coating formed of a resin such as vinyl chloride to insulate the core wire, and use conditions such as wiring place, application, power consumption, connection method, etc. The total length, the diameter of the core wire, the exposed length of the core wire, etc. are set so as to be suitable for the above.

  Moreover, in order to electrically connect a plurality of electrical components, a wire harness in which a plurality of electric wires are bundled may be used. And in this wire harness, the covering electric wire of a plurality of colors (for example, 13 colors) is used. In wire harnesses, crimp terminals crimped to the front and rear ends of a plurality of wires are connected together in one or more connectors (also referred to as housings), and electrical components are connected via the connectors. It is connected to the substrate. And in order to manufacture a wire harness, since it is requested | required that the kind and order of the electric wire connected to a connector are wired very correctly, in order to prevent a wiring mistake, each electric wire is color-coded. Things have been done.

  In recent years, along with the diversification of electrical products, the types of covered wires used for them have become extremely diverse, and small quantities so that they can be delivered in an appropriate amount at an appropriate time without being in stock. Production is generally done. In particular, in a wire harness used for a vehicle, it is also desired to produce a plurality of coated electric wires of a plurality of colors.

  However, in the conventional electric wire supply method, every time the type of electric wire changes, it is necessary to manually change the electric wire, so that the operation rate of the terminal crimping apparatus has been greatly reduced. Specifically, even if the processing capacity of the terminal crimping device 101 is 3000 lines / hour, if one minute is required to change the wires, the production amount per hour is 60 or less. In other words, in the case of high-mix low-volume production, productivity is extremely deteriorated, and as a result, an increase in manufacturing cost and an increase in burden on workers have been problems.

  Moreover, since the general electric wire drum is comparatively large, in order to arrange many of them, very large space was required and it was difficult to introduce equipment. In addition, when the wire wound around the electric wire drum becomes less, it must be replaced with a new electric wire drum. At this time, it is necessary to remove or set the large electric wire drum on site, The reduction in operating rate and the increase in the burden on workers were encouraged.

  If there is not enough space on site, place only one or frequently used wire drums in the vicinity of the terminal crimping device, and store all remaining wire drums in a warehouse or storage. According to this, when using a stored electric wire drum, the electric wire drum must be transported from a warehouse or the like to the vicinity of the terminal crimping device. Took a longer time to complete.

  Therefore, the applicant of the present application has previously proposed an electric wire processing system that reduces the burden on the operator and enables electric wire supply suitable for high-mix low-volume production. This includes a plurality of electric wire drums wound with different types of electric wires, and drum moving means for selecting one electric wire drum from the plurality of electric wire drums and moving the electric wire drum to a predetermined take-out position. The electric wire supply device is provided, and the electric wire wound around the electric wire drum at the take-out position can be supplied to the terminal crimping device. Moreover, the electric wire extended from the electric wire drum can be pulled out by an electric wire feeder, and the front-end | tip part of an electric wire can be supplied to a terminal crimping apparatus. According to this, in order to perform mechanically the operation | movement which moves the selected one electric wire drum to the predetermined extraction position, and the operation | movement which delivers the electric wire extended from the electric wire drum to a terminal crimping | compression-bonding apparatus, The work can be automated and the burden on the operator can be reduced.

  However, the decline in operating rate in terminal crimping equipment is not only due to wire switching, but also due to crimp terminal (reel) replacement work and applicator replacement work. Under the current production system, it has been difficult to increase productivity. That is, when the types of connectors and electric wires are changed, the applicator in the crimping mechanism and the crimp terminals supplied to the applicator need to be replaced accordingly, and the operation rate of the terminal crimping apparatus is greatly reduced. In particular, the applicator is handled integrally with the elevating member for operating the pressing member and the power mechanism of the terminal crimping device, and the shape of the pressing member and anvil varies depending on the shape of the crimping terminal. When there are many types of crimp terminals to be connected, many types of units have to be provided, and much time is required for replacement work including taking out and storing the units. In addition, a large warehouse is required to store the units. In addition, when the applicator is replaced, adjustment work is required, which is extremely laborious.

  Therefore, the present applicant has also proposed the following wire processing system. That is, an electric wire holder that receives a plurality of electric wires supplied from the electric wire supply device in order and that can be carried while being held in a predetermined arrangement, and an electric wire holder For the plurality of electric wires, the crimping device specifying means for specifying the terminal crimping device used for each crimping process from among the plurality of terminal crimping devices, the identification number of the identified terminal crimping device, and the wire holder And a guidance device that guides the operator as a portable destination. According to this, since a plurality of types of terminal crimping devices, which are a combination of a plurality of types of applicators and a plurality of types of crimping terminals, are arranged side by side, the types of connectors and wires are frequently used due to high-mix low-volume production. Even if it changes, it becomes possible to crimp a crimp terminal to the front-end | tip or back end of each electric wire, without replacing | exchanging an applicator or a crimp terminal.

JP-A-2005-166399

  However, in the above wire processing system, it is necessary to select at least one wire drum from a plurality of wire drums and to move the wire drum to a predetermined extraction position. It took a relatively long time for all of the plurality of electric wires to be fed into the holder. Further, when the number of types of electric wires is large, the number of electric wire drums is also increased, so that the configuration for moving the electric wire drums is very large. In addition, two or more electric wire drums arranged at relatively distant positions may be sequentially selected. In this case, the time required to supply the electric wires is promoted, and it is difficult to increase productivity. It was. In addition, since a large number of electric wire drums are moved simultaneously, a large drive means is required and energy consumption is increased.

  Then, this invention makes it a subject to provide the electric wire processing system which enables manufacture of the wire harness suitable for high-mix low-volume production, and can raise productivity in view of said actual condition.

The electric wire processing system according to the present invention has "a plurality of holding portions that can hold a plurality of wires, respectively, and an identification information storage portion that can read and write identification information, and hold a plurality of wires in a predetermined arrangement. An approximately rectangular parallelepiped electric wire holder that can be carried as is,
A holder conveying device for conveying the electric wire holder in a certain direction;
A plurality of electric wire supply devices that are arranged at predetermined intervals with respect to the conveying direction of the holder conveying device and supply electric wires in order to the electric wire holder conveyed by the holder conveying device;
A carrying-in device for carrying the wire holding tool into the holding device conveying device;
The carry-in device is
An endless conveyor belt wound around a drive roller and a driven roller;
A plurality of receiving portions arranged on the outer peripheral surface of the conveyor belt, wherein the longitudinal direction of the wire holder is substantially parallel to the transport direction of the holder transport device, and the plurality of wire holders are in the transport direction. A container that can be placed in a state in which the electric wire holder is aligned so as to be aligned in a substantially vertical direction with respect to
Conveyor driving means for rotating the drive roller in a certain direction so that the accommodating portion located on the upper side of the conveyor belt reaches the carry-in side of the holder transport device in order.
A holder feeding means for discharging the electric wire holder from the accommodating portion located on the carry-in side of the holder conveying apparatus and sending it to the holder conveying apparatus;
And an identification information writing means for writing identification information in the identification information storage section of the electric wire holder sent to the holder conveying device.

  Here, as the “electric wire holder”, a substantially comb-shaped one that can be inserted in a state where a plurality of electric wires are aligned from above can be exemplified. The “identification information storage unit” can write and read identification information (for example, an identification number), and specifically, an IC chip can be exemplified. The IC chip has a storage circuit for storing information, and writes information to the storage circuit or transmits stored information to the outside by a built-in power supply or a power supply supplied from outside. is there.

  According to the wire processing system of the present invention, a portable electric wire holder is used, and a plurality of electric wires can be held by a plurality of holding portions provided in the electric wire holder. And a holder conveyance apparatus and a some electric wire supply apparatus are used in order to send an electric wire to this electric wire holder. That is, an electric wire is sent from a different electric wire supply apparatus with respect to each clamping part, conveying an electric wire holder in a fixed direction. In addition, it becomes possible to send a mutually different electric wire with respect to each clamping part by making the kind of electric wire supplied from each electric wire supply apparatus mutually different. Moreover, since it becomes possible to arrange a plurality of electric wires according to the set wiring pattern, it is possible to manufacture a wire harness suitable for high-mix low-volume production, and to increase productivity.

  Moreover, the carrying-in apparatus is arrange | positioned next to the holder conveyance apparatus, and it becomes possible to send an electric wire holder sequentially with respect to a holder conveyance apparatus. Specifically, the carry-in device is configured such that the conveyor belt wound around the driving roller and the driven roller, a plurality of accommodating portions disposed on the outer peripheral surface thereof, and the driving roller is rotated in a certain direction to simultaneously move the plurality of accommodating portions. And a conveyor driving means. In particular, the plurality of accommodating portions are arranged such that the longitudinal direction of the wire holder is substantially parallel to the transport direction of the holder transport device, and the plurality of wire holders are arranged in a direction substantially perpendicular to the transport direction. . For this reason, if a conveyor drive means is operated, the some electric wire holder accommodated in the accommodating part of the upper side of a conveyor belt will be sent to the carrying-in side of a holder conveyance apparatus with an accommodating part in order. And the electric wire holder which reached | attained the carrying-in side is discharged | emitted from an accommodating part by a holder feeding means, and is sent to an electric wire conveyance apparatus. As described above, a plurality of wire holders in an empty state (a state in which no electric wires are held) can be stored, and the wire holders are fed into the holder transport device in order, so that the wire holders can be smoothly and appropriately timed. For example, it is possible to suppress a decrease in production efficiency due to, for example, a delay in loading the electric wire holder.

  Further, the carry-in device is provided with identification information writing means, and the identification information is written in the identification information storage unit of the electric wire holder. Thereby, it becomes possible to distinguish each electric wire holder carried in to a holder conveyance apparatus based on identification information, and it becomes possible to match each electric wire holder and the wiring pattern of an electric wire. That is, in each electric wire supply apparatus, it becomes possible to specify the clamping part which sends in an electric wire based on the identification information of an electric wire holder.

  Moreover, in the electric wire processing system of the present invention, “the accommodating portion of the carry-in device includes a guide portion that supports the electric wire holder and guides the electric wire holder toward the holder conveying device”. You may comprise.

  According to the electric wire processing system of the present invention, the accommodating portion of the carry-in device has the guide portion, supports the electric wire holder, and guides the sliding direction of the electric wire holder. For this reason, it becomes possible to smoothly feed the electric wire holder placed in the accommodating portion only by sliding it toward the holder conveying device, and the holder feeding means can have a relatively simple configuration.

  Specifically, the “holding tool feeding means” may be constituted by a cylinder that presses the electric wire holding tool positioned on the carry-in side of the holding-tool conveying device toward the holding-tool conveying device. According to this, after the electric wire holder has reached the carry-in side of the holder conveying device, when the piston rod of the cylinder is protruded, the electric wire holder can be pressed toward the holder conveying device side. The electric wire holder can be fed from the apparatus to the holder conveying device.

Moreover, in the electric wire processing system of the present invention, “the carry-in device is
A placement direction discriminating means for discriminating the orientation of the electric wire holder placed in the accommodating portion;
When it is determined that the direction of the wire holder is opposite to the normal direction, a feed operation prohibiting unit that prohibits a feed operation by the holder feed unit;
It may further comprise a receiving plate that receives and supports the electric wire holder in which the feeding operation is prohibited.

  By the way, as described above, in the case where the substantially rectangular parallelepiped electric wire holder is slid into the holder conveying device, the electric wire holder is erroneously set to be opposite to the housing portion. According to this, the wiring pattern of the electric wire is reversed left and right, and it may be carried in without writing identification information.

  On the other hand, according to the electric wire processing system of the present invention, the direction of the electric wire holder placed on the accommodating portion is individually determined. When it is determined that the direction of the wire holder is opposite to the normal direction, the feeding operation by the holder feeding means is prohibited. For this reason, it can prevent beforehand that a wire harness with a wrong wiring pattern is manufactured. In addition, since the receiving device is provided with a receiving plate, even if the electric wire holder that has not been sent to the holder conveying device is discharged from the top end of the upper surface of the conveyor belt, it can be received without dropping. As a result, it is possible to prevent the electric wire holder from being damaged by dropping.

Moreover, in the electric wire processing system of the present invention, “the holder transport device is
A transfer table capable of sliding the wire holder on the upper surface;
A roller mechanism in which a plurality of pairs of feed rollers that protrude from the upper surface of the transport table and feed in a state of sandwiching the electric wire holder by rotating in opposite directions are arranged at predetermined intervals in the transport direction; ,
Identification information reading means that is arranged corresponding to each of the electric wire supply devices and reads the identification information from the identification information storage unit of the electric wire holder sent by the feed roller;
Stop position determining means for individually determining the stop position of each of the wire holders based on the read identification information;
It may further comprise a conveyance control means for individually controlling each of the feed rollers so as to stop the electric wire holder at the stop position determined by the stop position determining means.

  The electric wire processing system of the present invention embodies the configuration of the “holding device conveying apparatus”. That is, the holder transport device includes a transport base that can slide the electric wire holder and a roller mechanism that slides the electric wire holder in a certain direction with the electric wire holder sandwiched therebetween. A plurality of sets of feed rollers are arranged at a predetermined interval in the transport direction. For this reason, by controlling the driving state of the roller mechanism, the electric wire holder can be transported or stopped at a predetermined position, and in particular, a plurality of sets of feed rollers in the roller mechanism can be controlled individually. It becomes possible to slide a plurality of electric wire holders separately on the carrier. For example, even when the electric wire is being supplied to a predetermined electric wire holder (that is, while the predetermined electric wire holder is stopped), if the supply of electric wires to other electric wire holders has been completed. These electric wire holders can be slid.

  Also, a plurality of identification information reading means are provided so as to correspond to each electric wire supply device, and the identification information is read from the identification information storage unit of the electric wire holder for the electric wire holder sent by the feed roller. And the stop position of each electric wire holder is determined individually based on the read identification information, and each feed roller is individually controlled so as to stop the electric wire holder at those stop positions. For this reason, the clamping part corresponding to identification information among a plurality of clamping parts can be made to oppose an electric wire supply apparatus.

Moreover, in the electric wire processing system of the present invention, “at least two reflecting portions that are formed side by side in the longitudinal direction on the bottom surface of the electric wire holder and reflect light;
A plurality of the holder transport devices are provided at predetermined intervals, and radiate light toward the wire holder passing therethrough and receive pulsed light reflected by the reflector, thereby passing through the reflector. Passing detection means for detecting
It may further comprise movable position recognition means for recognizing the current position of the wire holder based on the subsequent rotation speed or rotation time of the feed roller when passage of the reflecting portion is detected. Good.

  By the way, the more types of electric wires, the larger the number of electric wire supply devices and the longer the length of the holder conveying device. For this reason, even if the rotation speed of the feed roller is accurately controlled, errors are accumulated in the downstream region in the transport direction, and there is a possibility that the feed roller stops at a position deviated from the set stop position. In this case, there is a possibility that the electric wire supplied from the electric wire supply device cannot be sent to the target clamping unit.

  On the other hand, according to the electric wire processing system of the present invention, a plurality of passage detection means are arranged at predetermined intervals in the holder transport device, and whether or not the light is emitted and the light is received ( That is, it is determined whether or not the electric wire holder has passed based on whether or not the light is reflected by the reflecting portion. In particular, the bottom surface of the wire holder is formed with a plurality of reflecting portions arranged in the longitudinal direction, while the passage detection means passes when receiving pulsed light (on / off repeated state). Therefore, it is determined that the electric wire holder has been passed by another object (for example, the hand of the operator) even though the electric wire holder has not passed, that is, it prevents erroneous detection. Is possible.

  And when passage of a reflection part is detected, the present position of an electric wire holder is recognized based on the rotation speed or rotation time of the feed roller after the detection. Thus, every time the wire holder moves a predetermined distance, the current position of the wire holder is repeatedly recognized again, so that accumulation of errors is suppressed, and as a result, the wire holder is always stopped at an appropriate position. Is possible.

Further, in the electric wire processing system of the present invention, “the holding portion of the electric wire holder is supported to be displaceable between a closed position where the electric wire can be held and an open position where the electric wire can be inserted and removed. And is biased toward the closed position by the biasing means,
The holding device conveying device presses the holding portion of the wire holding device stopped at a position facing each of the electric wire supply devices, and holds the holding portion against the urging force of the urging means in the closed position. It may be configured to further include an opening operation means that can be forcibly displaced from the position to the opening position.

  According to the electric wire processing system of the present invention, the holding portion of the electric wire holder is supported to be displaceable between the closed position and the open position, and is urged toward the closed position by the urging means. For this reason, it becomes possible to clamp an electric wire in a closed position, and it becomes possible to insert and extract an electric wire in an open position. Further, each holding device transport device is provided with an opening operation means, and before executing the feeding of the electric wire, press the holding portion of the electric wire holder stopped at a position facing the electric wire supply device, The clamping part is forcibly displaced from the closed position to the open position against the urging force of the urging means. For this reason, when inserting the electric wire, it is possible to feed the electric wire by setting the holding portion to the open position, and on the other hand, the electric wire can be securely held after the feeding is completed. It can prevent that an electric wire deviates from a clamping part during conveyance of a holder.

  As described above, according to the electric wire processing system of the present invention, it is possible to quickly arrange the electric wires in accordance with the wiring pattern of the wire harness, and as a result, it is possible to perform the wiring processing suitable for high-mix low-volume production. In addition, a plurality of electric wire holders can be stored, and the electric wire holders can be supplied smoothly and at an appropriate timing, for example, due to a delay in loading of the electric wire holders. It becomes possible to suppress a decrease in production efficiency.

  Hereinafter, an electric wire processing system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 20. FIG. 1 is a schematic diagram showing a schematic configuration of an electric wire processing system.

That is, the clamping force is generated by pressing the receiving piece 19 downward. In addition, since the hole part 15 which accommodates the biasing means 18 and the receiving piece 19 is opening in the bottom face 14 of the holder main body 10, a press operation part (not shown) is inserted from the opening 20, and each receiving is carried out. If the piece 19 is pressed upward, the holding portions 13 can be individually displaced to the protruding side against the urging force of the urging means 18.

  A flange 21 is formed on the bottom surface 14 side of the wire holder 2 so as to protrude in the horizontal direction over the entire circumference.

For example, even while the electric wire is being supplied to the predetermined electric wire holder 2 (that is, while the predetermined electric wire holder 2 is stopped), the supply of electric wires to the other electric wire holder 2 is completed. If it has, it becomes possible to make those electric wire holders 2 slide.

  Also, in the holder transport unit 50, identification information reading means 58 that reads identification information from the identification information storage unit 24 of the electric wire holder 2 sent by the feed roller 56 is arranged corresponding to the electric wire supply unit 51. Yes. And the stop position of each electric wire holder 2 is individually determined based on the read identification information, and each feed roller 56 is individually controlled so as to stop the electric wire holder 2 at these stop positions. It is like that. For this reason, it becomes possible to make the clamping part 13 corresponding to identification information oppose the electric wire supply unit 51 among several clamping parts 13. FIG. Detailed control processing will be described later. Here, the information reading means 58 corresponds to the identification information reading means of the present invention.

  By the way, the more types of electric wires, the larger the number of electric wire supply units 51 correspondingly, and the longer the length of the holder transport unit 50. For this reason, even if the rotation speed of the feed roller 56 is controlled with high accuracy, errors are accumulated in the downstream area in the transport direction, and there is a possibility of stopping at a position deviated from the set stop position. In this case, there is a concern that the electric wire supplied from the electric wire supply unit 51 cannot be fed into the target clamping unit 13.

  Therefore, a plurality of passage detection means 61 are arranged at predetermined intervals in the holder transport unit 50 of this example. As shown in FIG. 18, the passage detection means 61 includes a light emitting unit 61a that emits light toward the electric wire holder 2 that passes above the holder conveyance unit 50, and light emitted from the light emitting unit 61a. And a light receiving portion 61b that receives the light when reflected by the two reflecting members 23, and determines whether or not the wire holder 2 has passed based on the presence or absence of reflection. In particular, as described above, the slit 14 which is a light passage hole for the reflecting member 23 is formed in the bottom surface 14 of the electric wire holder 2 side by side in the longitudinal direction. When light in a state of repeating ON / OFF is received, it is determined as passing. For this reason, it is possible to suppress the determination that the electric wire holder 2 has passed by another object (for example, the hand of an operator) even though the electric wire holder 2 has not passed. . When the passage of the slit 22 is detected, the current position of the wire holder 2 is recognized based on the rotation speed or the rotation time of the feed roller 56 after the detection. In this way, every time the wire holder 2 moves a predetermined distance, the current position of the wire holder 2 is repeatedly re-recognized, so that accumulation of errors is suppressed, and as a result, the wire holder 2 is always kept at an appropriate position. It can be stopped.

  Further, as shown in FIG. 6, each holder transport unit 50 is provided with an opening operation means 63 provided so as to be able to protrude from the upper surface of the transport table 55. The opening operation means 63 is composed of a cylinder, and before executing the feeding of the electric wire, the holding portion 13 (specifically, the receiving piece 19 in the holding portion 13) of the electric wire holder 2 stopped at a position facing the electric wire supply unit 51. ) Is pushed up from below, and the clamping portion 13 is forcibly displaced from the closed position (down position) to the open position (projection position) against the urging force of the urging means 18. For this reason, when inserting an electric wire, it becomes possible to send an electric wire by making the clamping part 13 into an open position. On the other hand, after the feeding is completed, the electric wire can be securely held by making it into a closed position. It becomes possible to do.

  On the downstream side of the holder transport unit 50, the second holder transport unit 64 in the array inspection device 36, the third holder transport unit 65 in the wire extension device 37, and the fourth hold in the holder discharge device 38. The tool conveyance unit 66 is connected in order, and it is possible to convey the electric wire holder 2 continuously. Each of the holder transport units employs substantially the same configuration, and transports the wire holder 2 by the rotation of the feed roller 56.

(Configuration of wire supply unit)
As shown in FIGS. 9 and 11, the electric wire supply unit 51 includes a housing 70 having a substantially rectangular side view and an inclined upper surface of the rear end portion, and a mechanism unit 71 (FIG. 10) disposed inside the housing 70. Reference) and an operating portion 72 disposed on the outside (particularly the side surface outside) of the housing 70. That is, a portion in contact with the electric wire L is disposed so as to protrude from the housing 70, and a mechanism for driving them is accommodated in the housing 70. A reel 73 (not shown in FIG. 9) for receiving the electric wire L fed from the electric wire drum 34 and a guide portion 74 for guiding the insertion direction of the electric wire L are supported by the operating portion 72 so as to be rotatable with respect to the housing 70. A pair of feed rollers that are arranged at predetermined intervals, are rotatably supported, and are fed with a rotational force to convey the electric wire L fed from the electric wire drum 34 toward the electric wire holder 2. 75, a pipe-shaped guide pipe 76 that guides the feeding direction of the electric wire L fed by the feeding roller 75, and an upper blade 85 and a lower blade 86 that move in the vertical direction and generate a shearing force. And a cutting blade 77 for cutting or peeling the electric wire L conveyed through the pipe 76.

  As shown in FIG. 10, the upper blade 85 and the lower blade 86 of the cutting blade 77 are connected to the sliding portion 89 via the arm portion 87, and the sliding portion 89 is vertically moved by the guide portion 88. It is slidably supported on. In addition, an elevating mechanism 90 that elevates and lowers the sliding portion 89 is provided inside the housing 70, and the interval between the upper blade 85 and the lower blade 86 can be changed by the operation of the elevating mechanism 90. ing. That is, with the electric wire L inserted between the upper blade 85 and the lower blade 86, the electric wire L is cut by operating the lifting mechanism 90 so that the upper blade 85 contacts the lower blade 86. Further, in the state where the electric wire L is inserted between the upper blade 85 and the lower blade 86 so that the end portion of the electric wire L protrudes by a predetermined length, the distance between the upper blade 85 and the lower blade 86 is the core wire of the electric wire L. The elevating mechanism 90 is operated so as to have a distance corresponding to the size of the wire, and then the wire L is pulled, whereby the covering material at the end of the wire L is removed.

  In particular, in this example, a movable chuck mechanism 78 is provided as means for pulling the electric wire L. The movable chuck mechanism 78 can be switched between a holding state in which the electric wire L guided by the guide pipe 76 is held and a non-holding state in which the electric wire L is not held, and the first is located closer to the guide pipe 76 than the cutting blade 77. It is supported so as to be movable between a position (shown by a solid line in FIG. 11) and a second position (shown by a two-dot chain line in FIG. 11) that is the wire holder 2 rather than the cutting blade 77.

  More specifically, as shown in FIG. 10, the movable chuck mechanism 78 includes a holding mechanism 96 that can be switched between a holding state and a non-holding state, and a slide mechanism 95 that slides the holding mechanism 96 in the front-rear direction. ing. The slide mechanism 95 has a motor 97 that generates a rotational force with the axial direction as a vertical direction, a pinion 98 attached to the rotation shaft of the motor 97, and meshes with the pinion 98 to rotate the motor 97 in the front-rear direction (in the drawing). A rack 99 that converts linear motion in the left-right direction), a sliding member 100 that is coupled to the rack 99 and whose movement direction is guided by the linear guide 101, and the clamping mechanism 96 and the sliding member 100 are coupled to each other. And a base member 102 that reciprocates. That is, by controlling the rotation direction and the number of rotations of the motor 97, the clamping mechanism 96 can be moved by an appropriate distance in the front-rear direction.

  On the other hand, the holding mechanism 96 is fixed to the base member 102 in a fixed state, and the direction perpendicular to the moving direction of the holding mechanism 96 (that is, the same as the conveying direction of the wire holder 2). The movable side holding member 104 is formed so as to be slidably supported in the direction) and forms a passage through which the electric wire L passes between the fixed side holding member 103 and the outer surface of the movable side holding member 104. A clamping operation member 105 that can move in the same direction as the movement direction of the clamping mechanism 96 is provided. That is, the movable-side clamping member 104 has a trapezoidal shape in plan view with the outer surface side inclined, and the clamping operation member 105 that contacts the movable-side clamping member 104 has an abutting surface that is opposite to the inclination of the movable-side clamping member 104. Therefore, by moving the clamping operation member 105 in the front-rear direction, the movable-side clamping member 104 is moved in the direction perpendicular to the movement direction of the clamping operation member 105, so that the fixed-side clamping member It becomes possible to change the space | interval with 103, ie, the width | variety of the path | route of the electric wire L. FIG. In this way, the non-holding state is achieved by widening the interval between the fixed-side clamping member 103 and the movable-side clamping member 104, and the holding state is reduced by reducing the interval between the fixed-side clamping member 103 and the movable-side clamping member 104. To do.

  By the way, in the case where the electric wire holder 2 (see FIG. 3) provided with the sandwiching portion 13 having an L-shaped cross section is used, in order to feed the electric wire L between the sandwiching portion 13 and the fixing plate 12, the sandwiching portion 13 is opened. However, when the gap is narrow, it is difficult to insert the electric wire L into the gap. Moreover, since the electric wire L cannot be supplied until the clamping part 13 which supplies the electric wire L opposes the electric wire supply unit 51, ie, until the electric wire holder 2 stops, the series of processing time is shortened. It becomes difficult. On the other hand, in this example, the electric wire gripping mechanism 80 is disposed between the cutting blade 77 and the electric wire holder 2, and the electric wire L is held by the gripping portion 81 of the electric wire gripping mechanism 80, and is lifted and swung. It is possible to make it. For this reason, by swinging the gripping portion 81, the electric wire L from the side that is the open side with respect to the gap between the sandwiching portion 13 having a substantially L-shaped cross section and the fixing plate 12 on the upper surface of the holder body 10 is provided. Can be inserted. If the gripping state is released and the gripping part 81 is raised after the electric wire L is inserted, the gripping part 81 can be returned to a predetermined height without interfering with the electric wire L. Accordingly, it is possible to reliably insert the electric wire L into the holding portion 13 of the electric wire holder 2, increase the series of processing speeds, and further increase productivity.

  By the way, since the electric wire L is supplied to each electric wire supply unit 51 from the separate electric wire drum 34, when the remaining amount of the electric wire L wound around the electric wire drum 34 decreases, or all the electric wires L are used up. In such a case, it is necessary to replace the electric wire drum 34 with a new drum. And when replacing | exchanging the electric wire drum 34, the supply of the electric wire L from the electric wire supply unit 51 will stop in the meantime, and the operation rate of the electric wire arrangement | sequence system 3 will be reduced.

  Therefore, in this example, the wire supply units 51 having the same structure are arranged opposite to each other on both the left and right sides of the housing 70, and the wires are supplied from one selected wire supply unit 51. In addition, it is comprised so that the electric wire L may be supplied to the two sets of electric wire supply units 51 from the separate electric wire drum 34 around which the same kind of electric wire was wound. Further, as shown in FIG. 11, there is provided a remaining amount detecting means 109 for detecting that the remaining amount of the electric wire L wound around each electric wire drum 34 has decreased. The remaining amount detecting means 109 detects the remaining amount of the electric wire L by detecting the difference between the length of the electric wire fed out from the electric wire drum 34 and the length of the electric wire L sent to the electric wire holder 2. . More specifically, the length of the electric wire L sent to the electric wire holder 2 is a predetermined measured length, but the length of the electric wire L fed from the electric wire drum 34 varies depending on the remaining amount of the electric wire L. The remaining amount of the electric wire L is detected using this. That is, since a motor (not shown) for feeding out the electric wire L rotates at a constant rotation number, when the remaining amount of the electric wire is large (that is, when the diameter of the electric wire wound around the electric wire drum 34 is large), When the remaining amount of the electric wire is small (that is, when the diameter of the electric wire is small), the length of the electric wire L fed out per unit time is different and the wire drum 34 and the reel 73 are bent. As the remaining amount of the electric wire L decreases, the remaining amount of the electric wire L becomes smaller. Therefore, in the remaining amount detecting means 109, the excess amount of the electric wire L is reduced, that is, the electric wire between the electric wire drum 34 and the reel 73. By detecting that the wire has changed from a bent state to a stretched state, it is determined that the remaining amount of the wire has decreased.

  And when the electric wire L is supplied from one electric wire supply unit 51, when the electric wire L of the electric wire drum 34 corresponding to the electric wire supply unit 51 decreases or when the electric wire L runs out, The wire supply unit 51 is stopped and the wire L is supplied from the other wire supply unit 51. For this reason, it is possible to continue supplying the electric wire L even during the replacement of the electric wire drum 34, and to further increase the operating rate of the electric wire supply unit 51. Note that when the wire supply unit 51 is switched, the stop position of the wire holder 2 is also changed accordingly, so that the wire L is accurately fed even when any wire supply unit 51 is selected.

(Configuration of wire guide device)
Next, a specific configuration of the wire guide device 39 will be described with reference to FIG. The wire guide device 39 is mounted on the support rod 140 extending from the housing 70 in the direction of supplying the wire, and is mounted from the support rod 140 via the arm portion 141, and the holding portion 13 and the fixing plate of the wire holder 2. 12 is interposed between the pair of holding plates 142 and the arm portion 141 and the holding plate 142 for guiding the electric wire inserted through the gap between the holding plate 142 and the extension line in the feeding direction. An open / close cylinder 144 that can be switched between a closed state and an open state in which the lower end side is opened with the upper end as a fulcrum is provided. A projecting portion 143 projecting outwardly in a “<” shape is formed at the central portion of the holding plate 142, and a rhombus passage is formed by abutting the pair of holding plates 142. According to this, the electric wire sent from each electric wire supply unit 51 and having passed through the pinching portion 13 of the electric wire holder 2 is guided along the extension line in the feeding direction, and is sent while maintaining a straight state. For this reason, even if the some clamping part 13 is arrange | positioned mutually close, when sending an electric wire, it prevents that an adjacent electric wire gets intertwined and it becomes possible to send in smoothly. When the feeding of the electric wire is completed, the protruding portion 143 is opened and the holding state is released, so that the electric wire holder 2 can be continuously conveyed.

(Wire feeding operation)
Subsequently, the operation of feeding the electric wire to the electric wire holder 2 will be described with reference to FIGS. 12 and 13, (e), (f), (g), and (i) show the state of the relationship between the electric wire holder 2 and the gripping portion 81 as viewed from the front, and the other drawings are the whole. The structure is shown as viewed from the right side. First, as shown in FIG. 11, when the pair of feed rollers 75 sandwiching the electric wire L are rotated in opposite directions (directions of arrows), the electric wire L fed from the electric wire drum 34 is conveyed by the feed roller 75, It is inserted between the upper blade 85 and the lower blade 86 of the cutting blade 77 through the guide pipe 76. When stripping the tip end side of the electric wire L, as shown in FIG. 12A, the movable chuck mechanism 78 is positioned at the first position on the guide pipe 76 side with respect to the cutting blade 77, and the guide The electric wire L guided by the pipe 76 is held. And as shown in FIG.12 (b), while making the space | interval of the upper blade 85 and the lower blade 86 into the distance corresponding to the magnitude | size of the core wire of the electric wire L, the state which clamped the electric wire L by the movable chuck mechanism 78 Pull on. Then, the covering material on the tip side of the electric wire L is removed.

  Thereafter, as shown in FIG. 12C, the feed roller 75 rotates to feed the electric wire L by a predetermined length. In this case, since the holding part 13 of the electric wire holder 2 is still in the closed position, the supplied electric wire passes above the holding part 13. At this time, the movable chuck mechanism 78 passes between the upper blade 85 and the lower blade 86 and moves to the second position on the electric wire holder 2 side with respect to the cutting blade 77. At this time, since the movable chuck mechanism 78 does not hold the electric wire L, the movable chuck mechanism 78 can be moved while feeding the electric wire L or regardless of the supply of the electric wire L.

  Next, as shown in FIGS. 12D and 12E, the wire L is gripped by the gripping portion 81 of the wire gripping mechanism 80, and the gripping portion 81 is further opened on the open side of the clamping portion 13 (counterclockwise in the drawing). ) And then the clamping part 13 is displaced to the open position (see FIG. 12F). Thus, since the clamping part 13 is protruded after moving the electric wire L diagonally upward, the clamping part 13 can be displaced without interfering with the electric wire L.

  Thereafter, as shown in FIGS. 13G and 13H, the gripping portion 81 is returned to the original position. According to this, it becomes possible to insert the electric wire L between the clamping part 13 and the fixing plate 12. And as shown in FIG.13 (i), while the holding | maintenance state of the electric wire L by the holding part 81 is cancelled | released, the electric wire L is sent only the set length by the feed roller 75. FIG. At this time, the clamping unit 13 remains open, and the gripping unit 81 moves upward after releasing the holding state. Moreover, the electric wire L sent by the feed roller 75 is guided by the wire guide device 39 and supported linearly.

  When the fed wire L reaches the set length, the operation of the feed roller 75 is stopped and the wire L is cut by the cutting blade 77 as shown in FIG. Thereafter, a peeling process is performed on the rear end side of the electric wire L. Specifically, as shown in FIG. 13 (k), the distance between the upper blade 85 and the lower blade 86 is set to a distance corresponding to the size of the core wire of the electric wire L, and the electric wire L is connected by the movable chuck mechanism 78. Pull to the wire holder 2 side in the clamped state.

  And as shown in FIG.13 (L), the clamping part 13 of the electric wire holder 2 is displaced to a closed position, and the electric wire guide apparatus 39 is made into an open state after that. Thereby, while the electric wire L is clamped by the clamping part 13, the electric wire holder 2 can be conveyed. The movable chuck mechanism 78 passes between the upper blade 85 and the lower blade 86 and returns to the first position closer to the guide pipe 76 than the cutting blade 77. Thereby, a series of processes related to the feeding of the electric wire is completed.

[Configuration of holding device carry-in device]
Next, a specific configuration of the holder carry-in device 35 will be described with reference to FIG. FIG. 8A is a side view of the holder loading device 35, and FIG. 8B is a plan view (partially cross-sectional view) of the holder loading device 35. 8A shows a state where the electric wire holder 2 is placed, and FIG. 8B shows a state where the electric wire holder 2 is not placed.

  The holding device carrying-in device 35 is arranged on the outer peripheral surface of the conveyor belt 153 and is arranged on the outer peripheral surface of the endless conveyor belt 153 wound around the driving roller 151 and the driven roller 152, the motor 150 for applying a rotational force to the driving roller 151. And a plurality of accommodating portions 154 on which the tool 2 can be placed. As shown in FIG. 5, the accommodating portion 154 has a longitudinal direction of the electric wire holder 2 substantially parallel to the conveyance direction of the holder conveyance unit 50, and the plurality of electric wire holders 2 are substantially perpendicular to the conveyance direction. It is possible to place the electric wire holders 2 in an aligned state so as to line up. That is, when the motor 150 is rotated in a certain direction, the accommodating portion 154 located on the upper side of the conveyor belt 153 sequentially reaches the carry-in side of the holder conveyance unit 50. Here, the motor 150 corresponds to the conveyor belt driving means of the present invention.

  Further, as shown in FIG. 5, a holder feeding cylinder 156 is disposed on the upstream extension line with respect to the holder transport unit 50, and the holder transport unit 35 carries the holder transport unit 50 into the carry-in side. The electric wire holder 2 that has reached the position is discharged from the accommodating portion 154 by the pressing operation of the holder feeding cylinder 156 and is sent to the holder conveying unit 50. Thus, while being able to store a plurality of wire holders 2 in an empty state (a state in which no electric wires are held) and sequentially feeding them to the holder transport unit 50, the wire holders 2 can be smoothly and It can be supplied at an appropriate timing, and for example, it is possible to suppress a decrease in production efficiency due to a delay in loading of the electric wire holder 2. Here, the holder feeding cylinder 156 corresponds to the holder feeding means of the present invention.

  The holding portion 154 of the holder loading device 35 has a bowl shape with a concave cross section, supports both sides of the electric wire holder 2 by standing side walls, and faces the electric wire holder 2 toward the holder conveyance unit 50. It also acts as a guide unit for guiding. For this reason, it becomes possible to smoothly feed the electric wire holder 2 placed in the accommodating portion 154 by simply sliding it toward the holder conveyance unit 50, and this can be realized with a relatively simple configuration using a cylinder. Is possible.

  Further, as shown in FIG. 8B, the holder loading device 35 is provided with identification information writing means 157, and the identification information for identifying the wire holder 2 is the identification information of the wire holder 2. It is written in the storage unit 24. Thereby, it becomes possible to distinguish each electric wire holder 2 carried into the holder conveyance unit 50 based on identification information, and it becomes possible to associate each electric wire holder 2 and the wiring pattern of an electric wire. Become. That is, in each electric wire supply unit 51, it becomes possible to specify the clamping part 13 which sends in an electric wire based on the identification information of the electric wire holder 2. FIG. Details will be described later.

  By the way, as described above, when the substantially rectangular parallelepiped electric wire holder 2 is slid into the holder conveying unit 50, the electric wire holder 2 may be erroneously set in the opposite direction with respect to the housing portion 154. Yes, according to this, the wiring pattern of the electric wire becomes a left-right reverse wiring.

  Therefore, in this example, there is provided a mounting direction discriminating means 161 (see FIG. 19) for individually discriminating the direction of the electric wire holder 2 placed in the housing portion 154, and the electric wire holder 2 has a proper orientation. When it is determined that the direction is opposite to the direction, the feeding operation by the holder feeding cylinder 156 is prohibited. For this reason, it can prevent beforehand that a wire harness with a wrong wiring pattern is manufactured. In addition, a pair of receiving plates 160 that receive and support the electric wire holder 2 that has not been sent to the holder transport unit 50 are further downstream than the carry-in side of the holder transport unit 50 in the holder transport device 35. It is arranged on both the left and right sides. For this reason, even if the electric wire holder 2 that has not been sent to the holder conveyance unit 50 is discharged from the top end side of the upper surface of the conveyor belt 153 (that is, the concave accommodating portion 154 is inclined along the peripheral surface of the drive roller 151). Even if the electric wire holder 2 can no longer be supported, the electric wire holder 2 can be received without being dropped, and the electric wire holder 2 can be prevented from being damaged by dropping. The configuration of the placement direction discriminating means 161 is not particularly limited. In this example, light is emitted to the arrangement position of the slit 22 formed on the bottom surface 14 of the wire holder 2 and is reflected by the reflecting member 23. By detecting whether or not the light is reflected, it is determined whether or not the mounting direction is normal.Instead, the identification information is written in the identification information storage unit 24. It is also possible to determine the orientation of the wire holder 2 by determining whether were rare.

[Configuration of array inspection equipment]
Next, a specific configuration of the array inspection apparatus 36 will be described with reference to FIGS. The arrangement inspection device 36 images the plurality of electric wires arranged by the electric wire holder 2 with respect to the electric wire holder 2 carried into the second holder conveyance unit 64, and the output of the imaging device 170. The color recognition unit 171 (see FIG. 19B) for recognizing the color change in the wiring pattern based on the color change, the color change recognized by the line color recognition unit 171 and the management computer 40 described later. A wiring check unit 172 that compares the wiring patterns with each other and determines whether or not they match each other, and a display device 173 that displays a result of determination by the wiring check unit 172 are provided. That is, it is configured to check whether or not a plurality of electric wires are arranged in the order according to the wiring pattern by changing the color. Therefore, the operator can grasp whether or not the wiring of the electric wire is correct, that is, whether or not there is a wiring mistake, by visually recognizing the display device 173. When the recognized color change and the wiring pattern do not match, a display indicating that there is a wiring error and a notification of the number of the electric wires not matching are given by voice.

[Configuration of wire extension device]
Next, a specific configuration of the wire extending device 37 will be described with reference to FIGS. FIG. 14 is a perspective view showing the configuration of the main part of the wire extension device 37. The wire extending device 37 includes a wire holding mechanism 175 capable of separately holding the rear ends of the plurality of wires supplied by the plurality of wire supply units 51 and arranged in the wire holder 2, and the wire holding In a state where the tool 2 is fixed, the electric wire holding mechanism 175 is moved in a direction away from the position approaching the third holding device transport unit 65, whereby the electric wire held by the electric wire holding mechanism 175 is moved with respect to the electric wire holder 2. And an electric wire slide mechanism 176 that slides. The electric wire clamping mechanism 175 is erected from the upper surface of the base member 183 which is bent and formed in a substantially convex cross section, and is arranged at the same interval as the interval of the clamping portion 13 in the electric wire holder 2. A plurality of clamping cylinders 184 are provided. In the clamping cylinder 184, the piston rod 186 can protrude and retract through the base member 183. When the piston rod 186 protrudes, the clamping cylinder 184 comes into pressure contact with the support mat portion 185 fixed to the inside of the bottom surface of the base member 183. It becomes possible to clamp the rear end side of the electric wire L in cooperation with the mat portion 185. In addition, the extension part 187 protrudes and is formed in the opposite side of the 3rd holder conveyance unit 65 in the base member 183, and it can support without bending the rear-end side of the electric wire protruded from the electric wire holder 2. FIG. It has become.

  On the other hand, the electric wire slide mechanism 176 includes a base plate 188 that extends greatly rearward, a motor 189 that is supported with the axial direction of the rotation shaft as a vertical direction, and a pinion 190 that is attached to the rotation shaft of the motor 189. A rack 191 that meshes with the pinion 190 and changes the rotational movement of the motor 189 to a linear movement in the direction (front-rear direction) perpendicular to the conveying direction of the wire holder 2, and the rack 191 and the electric wire holding mechanism 175. And a sliding member 192 to be connected. That is, by rotating the motor 189 in a certain direction, it is possible to move the wire clamping mechanism 175 including the plurality of clamping cylinders 184.

  According to this, until all the electric wires L are arranged in the electric wire holder 2, it can be made to convey, without extending the rear end side of the electric wires L too much, On the other hand, all the electric wires L were arranged. Later, these electric wires L can be pulled out together. Accordingly, the rear end portion of the electric wire L is extended from the electric wire holder 2 even though the electric wire supply unit 51 is arranged in the state of being close to the holder conveying unit 50, and as a result, a crimp terminal ( (Not shown) can be easily crimped.

  Further, in the electric wire extension device 37, the protruding length adjusting means 194 (Fig. 5) adjusts the protruding lengths of the plurality of electric wires separately by individually setting the pinching release timing in each pinching cylinder 184. 19 (c)). That is, when the set protrusion length is short, the drawing of the electric wire is interrupted by releasing the clamping cylinder 184 at an early stage. On the other hand, when the set protrusion length is long, the clamping cylinder 184 By slowing the release, the drawn wire is lengthened. For this reason, it becomes possible to adjust the protrusion length of several electric wires separately, for example, the protrusion length which considered the difference of the pitch in a connector (housing housing) and the space | interval of the clamping part 13 in the electric wire holder 2. Accordingly, it is possible to prevent the occurrence of bending due to the surplus of only a part of the electric wires, such as the electric wire held by the central holding portion 13.

  The best mode for carrying out the present invention has been described above, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention as described below. Improvements and design changes are possible.

  That is, in the above-described embodiment, the information display device 250 displays the second and subsequent identification numbers and the connector information, but in addition to this, information regarding the color of the electric wire may be displayed. . More specifically, when the crimping process is performed in each terminal crimping device 4, crimping is performed in order from the electric wire on the end side, but the electric wire holder 5 holds a plurality of electric wires in a parallel state. Therefore, there is a concern that it may be mistaken which end side electric wire is the first electric wire. Therefore, the information about the color of the first electric wire is transmitted from the management computer 40 to the first terminal crimping device 4 and the information about the color is displayed on the information display device 250 of the terminal crimping device 4. preferable. According to this, when the crimping process is performed in the first terminal crimping device 4, it is determined whether or not the color displayed on the information display device 250 matches the color of the electric wire fed into the terminal crimping device 4. As a result, it becomes possible to prevent the generation of defective products by performing the crimping process with the last wire mistaken for the first wire. Note that not only the color of the first electric wire but also the colors of the second and subsequent electric wires may be transmitted to the respective terminal crimping devices 4 and displayed. According to this, even if the first and last wires are the same color, it is possible to recognize the mistake of the wires at a relatively early stage by checking the colors of the second and subsequent wires. It is possible to prevent unnecessary work as much as possible. Further, since the work can be performed while checking whether or not the colors of the respective electric wires are correct, it is possible to reduce connection errors and to give the worker a sense of security.
