Description

  The present invention relates to an electric wire supply device, and more particularly to an electric wire supply device capable of supplying various types of electric wires to a terminal processing device that performs terminal processing of electric wires.

  As a terminal processing device, there is known a terminal crimping device that removes a covering material from an end of an electric wire, crimps a terminal to the end, and cuts the electric wire into a predetermined length. Some of these terminal crimping devices can crimp a terminal to both the front end portion and the rear end portion of the electric wire.

  Specifically, as shown in FIG. 10, the terminal crimping device 101 includes a wire crimping device 102, a first crimping mechanism 103 for crimping a terminal to the front end side and the rear end side of the wire L, and a second crimping device. A mechanism 104; a cutting mechanism 105 that cuts the electric wire L and removes the covering material at the end of the electric wire L; an electric wire feeding mechanism 106 that feeds the distal end side of the electric wire L to the first crimping mechanism 103; A chuck mechanism (not shown) that holds L and feeds the rear end side of the wire L to the second crimping mechanism 104 and stores the wires L that have been crimped on the terminals T, and then collects a predetermined number of wires L and discharges them to the outside. And a discharge device (not shown).

  The first crimping mechanism 103 and the second crimping mechanism 104 have the same basic configuration, and an applicator 109 for crimping a terminal is attached to the frame member 110. That is, a notch 111 is formed on the side surface of the frame member 110, and the applicator 109 is attached in the notch 111. Specifically, the upper unit 112 of the applicator 109 is attached above the notch 111, and the lower unit 113 of the applicator 109 is attached below the notch 111.

  The electric wire feeding mechanism 106 includes an electric wire take-in guide 157, an encoder 158 for measuring the length of the electric wire L, a pair of rollers 159 disposed at a predetermined distance, and the like. (See Patent Document 1).

  On the other hand, as a method of supplying electric wires to the terminal crimping apparatus 101, for example, a plurality of electric wire drums wound with different electric wires are provided, and an electric wire to be processed from the plural electric wire drums is manually applied to the terminal crimping apparatus 101. 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 106 through the electric wire collecting device 102 of the terminal crimping device 101, and thereafter, a pair of wires provided in the electric wire feeding mechanism 106. The electric wire can be fed out from the electric wire drum by the power (pulling operation) of the roller 159.

  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 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 wire supply method, every time the type of the wire is changed, it is necessary to manually change the wire, so that the operation rate of the terminal crimping device is 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, A decrease in the operating rate and an 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.

  In addition, constructing a so-called automatic conveyance system that appropriately selects a wire drum to be processed from a plurality of wire drums stored in the storage, and automatically conveys and sets the wire drum to the terminal crimping device. However, such a system is an extremely large-scale facility, and enormous costs are required.

  Then, this invention makes it a subject to provide the electric wire supply apparatus which enables the electric wire supply suitable for high-mix low-volume production while reducing an operator's burden in view of said actual condition.

The electric wire supply device according to the present invention is “a supply device main body for supplying an electric wire to an end treatment device of an electric wire,
A plurality of the supply device body, a cylindrical receiving box portion having an insertion port on at least one end side,
A box-shaped case portion that is removably accommodated in the receiving box portion through the insertion port, a drum support portion that rotatably supports an electric wire drum on which an electric wire is wound, and the case A cassette-type electric wire feeding portion having an electric wire guide portion that is provided in a portion and feeds an electric wire wound around the electric wire drum from a predetermined portion in the case portion in a certain direction,
The supply device main body has the plurality of receiving box portions arranged in a loop shape along a predetermined vertical surface in a state where the direction of the insertion port is aligned in the same direction, and the vertical shape is maintained while maintaining the loop shape. It has a rotating mechanism that rotates on the surface. "

  Here, examples of the “terminal processing device” include a terminal crimping device that crimps a terminal to an end of an electric wire. The configuration of the “rotating mechanism” is not particularly limited, but may be configured from an endless chain that rotates on a plane while maintaining a loop shape, and a motor that applies a rotational force to the chain. Further, when the “cassette type electric wire feeding portion” is accommodated in the “receiving box portion”, the “electric wire guide portion” may be positioned on one end side (that is, the insertion port side) of the receiving box portion. You may make it locate in the other end side of a part.

  According to the electric wire supply device of the present invention, when the electric wire drum is supported by the drum support portion, the electric wire drum can be rotated in the case portion. Since the electric wire extended from the electric wire drum is routed to the outside of the case portion through the electric wire guide portion, if the tip of the electric wire protruding from the case portion is pulled outside the case portion, the electric wire drum It is possible to feed the wound electric wire out of the case portion. Moreover, this case part comprises the cassette type electric wire feeding part, and can be accommodated in the cylindrical receiving box part provided in the supply apparatus main body. And if a cassette type electric wire feeding part is accommodated in a receiving box part, it will become possible to pay an electric wire from the receiving box part. In particular, since the supply device main body is provided with a plurality of receiving box portions, different types of electric wires can be supplied from the supply device main body as needed.

  In particular, since it is a cassette type, the work of attaching the electric wire drum to the supply device main body becomes extremely easy. Further, since the electric wire is drawn out from the determined position in a certain direction, the electric wire can be smoothly delivered. Furthermore, when replacing the electric wire drum, the cassette-type electric wire feeding portion is taken out from the receiving box portion, and the electric wire drum housed in the case portion is replaced. Therefore, replacement work in a safe place is possible. In addition, even when the electric wire drum is being replaced, it is possible to continue supplying the electric wire from the receiving box portion in which the other electric wire drum is accommodated.

  In addition, the plurality of receiving box portions are arranged in a loop shape along a predetermined vertical plane with the direction of the insertion port aligned in the same direction, and the loop shape is maintained when the rotation mechanism is operated. Rotate on a vertical surface. For this reason, it becomes possible to move each electric wire drum to a predetermined extraction position. In addition, a plurality of cassette type electric wire feeding portions can be regularly arranged and can be supported with a relatively simple structure. Therefore, it is possible to hold a large number of electric wire drums even in a narrow space, and thus it is possible to reduce the size of the electric wire supply device. In particular, since it is arranged in a loop along a predetermined vertical plane, it becomes possible to displace each rotating drum in the horizontal direction and the vertical direction by only one rotating mechanism, and the selected rotating drum Can be easily moved to a predetermined removal position. That is, it is not necessary to employ a complicated configuration in which a device that slides in the horizontal direction and a lifting device are combined, and the device can be manufactured at a relatively low cost and the device can be further downsized.

Further, in the electric wire supply device of the present invention, “the rotating mechanism is disposed along the vertical surface and wound around a plurality of sprockets, and the chain via any one of the sprockets. A rotation drive source for applying a rotational force,
The plurality of receiving box portions may be arranged at predetermined intervals along the outer peripheral edge of the chain and radially connected to the chain ”.

  According to the electric wire supply device of the present invention, when a rotational drive source such as a motor operates, the rotational force is applied to the chain, and the chain rotates while being wound around the sprocket. Since the plurality of receiving box portions are radially connected to the outer peripheral edge of the chain at a predetermined interval, the plurality of receiving box portions can be rotated on the vertical plane while maintaining the loop shape. In particular, since it is connected so as to be radial, it is possible to insert a cassette type electric wire feeding portion from the back side by opening the back side of the receiving box portion, for example, to make the front of the wire supply device Even when it is closed with a plate or the like, the electric wire drum can be easily attached to and detached from each receiving box.

Further, in the electric wire supply device of the present invention, “a movement control for controlling the rotation driving source and moving the receiving box portion of the electric wire designated as the supply target from the plurality of receiving box portions to a predetermined take-out position. Means,
While pulling out the electric wire extended from the cassette type electric wire feeding portion accommodated in the receiving box portion arranged at the take-out position and accommodated in the receiving box portion, the tip portion of the electric wire is It may be further provided with an electric wire feeder that supplies the terminal processing device.

  Here, the configuration of the “wire feeder” is not particularly limited. For example, a pair of feed rollers that feed the wire by rotating and a wire fed by the feed roller are guided in a certain direction. It can comprise from the cylindrical guide member to do. In addition, a chuck portion that can hold the tip of the electric wire, a support rod that is disposed between the terminal processing device and the supply device main body and that slidably supports the chuck portion, and the chuck portion is slid along the support rod. You may make it comprise from the drive source to move.

  According to the wire supply device of the present invention, when one receiving box part is instructed as a supply target from among a plurality of receiving box parts, the movement control means controls the rotation drive source, and the specified receiving box part Is moved to a predetermined take-out position. In addition, an electric wire feeder is provided so as to face the extraction position, and the electric wire feeder pulls the electric wire from the cassette-type electric wire supply portion at the extraction position and feeds the tip portion of the electric wire to the terminal processing device. Deliver.

  Thus, in order to mechanically perform the operation of moving the selected one receiving box portion to a predetermined take-out position and the operation of delivering the electric wire extended from the cassette type electric wire feeding portion to the terminal processing device, A series of operations can be automated, the burden on the operator can be reduced, and an electric wire to be processed can be surely and quickly supplied.

  Further, in the electric wire supply device of the present invention, “a plurality of sets of the supply device main body including the chain to which the plurality of receiving box portions are connected and the rotation driving source for rotating the chain are arranged in parallel. The configuration can also be adopted.

  By the way, when creating a wire harness, for example, covered wires of a plurality of colors (for example, 13 colors) are used, and the number of patterns combining these colors with the material and diameter of the wire is 100 or more. In some cases. And in order to accommodate the electric wire drum in which these electric wires were wound in a separate receiving box part, very many receiving box parts must be prepared. However, if such a large number of receiving box portions are arranged at predetermined intervals along the outer peripheral edge of the chain, the rotational load becomes extremely large and it may be difficult to rotate. In addition, since the inner diameter of the loop-shaped chain is increased, the apparatus may be increased in size. In addition, if the wire drum that is currently being fed that is located at a predetermined position is far away from the housing position of the wire drum that is required for the next processing, the moving distance of the wire drum becomes longer and the next processing is performed. In this case, the electric wire cannot be supplied promptly.

  On the other hand, according to the electric wire supply device of the present invention, since a plurality of sets of supply device main bodies are arranged in parallel, it is possible to distribute the number of necessary receiving box portions. In other words, when the number of types of electric wires is extremely large, the number of receiving box portions corresponding to each of them is extremely large. In this example, a plurality of supply device main bodies are provided so that the receiving boxes connected to one chain are provided. It becomes possible to limit the number of copies. For this reason, it is possible to prevent the rotational load from becoming large and to prevent the inner diameter of the chain from becoming extremely large. Furthermore, it is possible to shorten the time required to move the required electric wire drum to the take-out position, and it is possible to further increase the operating rate of the terminal processing device.

Moreover, in the electric wire supply device of the present invention, “a movable base member that is mounted so as to be slidable in a horizontal direction around the take-out position while placing the plurality of sets of supply device bodies;
A horizontal driving source for moving the movable base member in the horizontal direction;
In the case where the supply device main body including the receiving box portion instructed as a supply target is opposed to the wire feeding device, the movement control means moves the receiving box portion only by the rotation drive source. When the supply device body including the receiving box portion designated as the supply object is not opposed to the wire feeding device, the feed device body is turned so as to face the wire feeding device. The movable base member may be moved in the horizontal direction by a horizontal driving source, and the receiving box portion may be rotated to the take-out position by the rotational driving source.

  According to the electric wire supply device of the present invention, a plurality of sets of supply device main bodies are placed on the movable base member and are slidable in the horizontal direction. That is, when the horizontal driving source operates, the movable base member moves in the horizontal direction, and a plurality of sets of supply device bodies are displaced simultaneously. Then, the movement control means determines whether or not the supply device main body including the receiving box portion is opposed to the wire feeding device when the receiving box portion in which the predetermined electric wire drum is accommodated is designated. When facing each other, the receiving box portion is rotated to the take-out position only by the rotation driving source without operating the horizontal driving source. On the other hand, when the supply device body including the receiving box portion does not face the wire feeding device, the movable base member is moved in the horizontal direction by the horizontal driving source so as to face the wire feeding mechanism, and The receiving box is rotated to the take-out position by the dynamic drive source. In this way, by sliding a plurality of supply device bodies horizontally around the wire feeder, any wire drum distributed and provided to a plurality of sets of supply devices can be controlled by a single wire feeder. It becomes possible to let out an electric wire.

In addition, instead of adopting the above configuration, in the electric wire supply device of the present invention, “two sets of the supply device main bodies are arranged adjacent to each other,
When any one of the receiving box portions is designated as a supply target, one of the supply device main bodies including the receiving box portion is selected, and the tip of the wire feeder is selected on the supply device main body side. It may be further provided with a swing drive unit that turns the electric wire feeder to a predetermined position.

  According to the electric wire supply device of the present invention, since two sets of supply device main bodies having a loop shape are arranged adjacent to each other, it is possible to make the extraction positions in the respective supply device main bodies adjacent to each other. Also, a swing drive unit for turning the wire feeder is provided, and when any one receiving box is specified, one supply device body including the receiving box is selected, and the wire feeder The tip is pivoted to point to the selected delivery position of the supply device body. In this way, by only slightly changing the direction of the wire feeding device, it is possible to feed out the wires from the wire drums provided in the respective feeding device main bodies without sliding the feeding device main bodies. Therefore, it is possible to reduce energy loss caused by moving the plurality of supply device main bodies and to further reduce the size of the entire device. Moreover, even when the electric wire is being fed out from the one supply device main body side, if the electric wire to be fed out is included in the other supply device main body side, before the feeding operation ends, Preparation of the next electric wire, that is, the receiving box portion in which the electric wire is accommodated can be moved to the take-out position, and as a result, the setup time associated with the replacement of the electric wire can be further shortened.

  As described above, according to the electric wire supply device of the present invention, it is possible to reduce the burden on the operator and to supply electric wires suitable for high-mix low-volume production. In addition, since the plurality of receiving box portions are arranged in a loop along a predetermined vertical plane, it becomes possible to displace each rotating drum in the horizontal direction and the vertical direction by only one rotating mechanism. The selected rotating drum can be easily moved to a predetermined take-out position.

And a device 4. Here, the terminal crimping apparatus 2 corresponds to the terminal processing apparatus of the present invention.

  As the terminal crimping device 2, a configuration substantially similar to that of the conventional terminal crimping device 101 described above with reference to FIG. 10 is adopted, and the wire L is fed in a straight line without changing the direction of the wire L being processed. It is possible to process while. That is, as shown in FIG. 1, the terminal crimping device 2 includes a first crimping mechanism 103 for crimping a terminal to the distal end side of the wire L and a second crimping for crimping a terminal to the rear end side of the wire L. The mechanism 104, the first cutting mechanism 105a having a cutting blade for removing the covering material at the end portion of the electric wire L, the second cutting mechanism 105b having the cutting blade for cutting the electric wire L, and the leading end side of the electric wire L are set to the first side. An electric wire feeding mechanism 106 that feeds the crimping mechanism 103 is provided. Further, as a new configuration that is not provided in the conventional terminal crimping device 101, a pair of feed rollers 110 that are disposed on the downstream side of the second crimping mechanism 104 and can clamp and feed the electric wire L are provided. It has been.

  The wire feeding mechanism 106 includes a wire take-in guide 157, an encoder 158 for measuring the length of the wire L, a pair of rollers 159 spaced apart by a predetermined distance, and a tip for detecting that the tip of the wire L has passed. It comprises a detection sensor 160 and the like. The pair of rollers 159 can move so as to approach and separate from each other, and the roller 159 is driven to rotate by roller driving means (not shown), and the direction of rotation and the number of rotations are controlled to control the electric wire. L is sent for an arbitrary length, and feedback control by the encoder 158 is also performed.

  In addition, in the conventional terminal crimping apparatus 101 shown in FIG. 10, the wire crimping apparatus 102 that corrects the bending bend of the electric wire and the like is provided, but the terminal crimping apparatus 2 of this example is provided with the wire crimping apparatus. In addition, the wire feeding device 3 is adapted to perform scraping (details will be described later).

  As shown in FIG. 2, the electric wire supply device 3 includes two sets of supply device main bodies 16 arranged adjacent to each other, and each of the supply device main bodies 16 is a front surface of the electric wire supply device 3 ( A plurality of receiving boxes 15 arranged in a loop (substantially rectangular) along a vertical plane parallel to the terminal crimping device 2 side), and a drive mechanism 11 for moving these receiving boxes 15. Configured. The drive mechanism 11 rotates the plurality of receiving box portions 15 while maintaining the loop shape, and moves one receiving box portion 15 selected from the plurality of receiving box portions 15 to a predetermined take-out position, for example, FIG. In No. 2, it is moved to “A1” and “A2” positions. More specifically, the electric wire supply device 3 has a state in which the insertion ports 23 (details will be described later) in the respective receiving box portions 15 are aligned in the same direction, specifically, all the insertion ports 23 face the back side. In addition, the plurality of receiving box portions 15 are arranged in a substantially rectangular loop shape, and the vertical shape is maintained while maintaining the loop shape so that the selected predetermined receiving box portion 15 is located at the extraction position A1 or the extraction position A2. It is configured to rotate on the surface. The drive mechanism 11 applies rotational force to the chain 13 via any one of the four sprockets 12 arranged along the vertical plane, the endless chain 13 wound around the sprocket 12, and any one sprocket 12. A plurality of receiving box portions 15 are arranged at predetermined intervals along the outer peripheral edge of the chain 13, and are radially connected to the chain 13. The rotating shaft 18 of the motor 17 and one sprocket 12 are connected by an endless belt 19 so that the rotational force of the motor 17 is transmitted to the chain 13 via the belt 19. Here, the drive mechanism 11 corresponds to the rotation mechanism of the present invention, and the motor 17 corresponds to the rotation drive source of the present invention.

  As shown in FIGS. 3 and 4, the receiving box portion 15 is a cylindrical member having a substantially rectangular parallelepiped shape, and an insertion port 23 for inserting the cassette type electric wire feeding portion 30 is provided on the side surface on one end side. It has been. Further, a locking member 24 that can be elastically deformed outward with the fixing portion 24a as a fulcrum is provided on the insertion port 23 side of the receiving box portion 15, and the locking member 24 is manually resisted against the elastic force. By bending outward, the cassette type electric wire feeding portion 30 can be inserted and removed, and after inserting the cassette type electric wire feeding portion 30 into the receiving box portion 15 and releasing the hand, the locking member 24 is released. Is restored to its original state by the elastic force, and the cassette type electric wire feeding portion 30 (hereinafter simply referred to as “cassette portion 30”) is prevented from being detached from the receiving box portion 15 by the claw portion 24b at the tip. It has become.

  Although not shown, a stopper 25 that restricts the insertion position of the cassette part 30 is provided on the inner bottom surface of the receiving box part 15. This stopper 25 is a substantially G-shaped member, and only the end side 25a is fixed, and the central side piece 25b with one end notched is elastically deformable in the insertion / removal direction. That is, when the cassette part 30 is inserted into the receiving box part 15, the end part abuts on the piece part 25b, and the piece part 25b is elastically deformed, that is, the cassette part 30 is directed toward the insertion port 23. It will be in the pressed state. At this time, since the front end of the cassette unit 30 is locked by the locking member 24, the receiving box unit 15 does not jump out of the insertion port 23, and the front end of the cassette unit 30 is aligned with the insertion port 23. Retained. On the other hand, when the locking member 24 is elastically deformed by the releasing operation, the locking state of the locking member 24 is canceled, and the cassette portion 30 is pushed out from the insertion port 23 by the elastic force of the one portion 25b of the stopper 25. Thereby, the cassette unit 30 can be easily pulled out.

  On the other hand, as shown in FIGS. 4 and 5, the cassette portion 30 includes a case portion 33 having a substantially U-shaped cross section having a bottom plate 31 and a pair of side plates 32 erected from both sides thereof, and a pair of side plates 32. And a drum support portion 38 that rotatably supports the electric wire drum 36 around which the electric wire L is wound. In addition, although the magnitude | size of the electric wire drum 36 is not specifically limited, In this example, the comparatively small drum whose diameter is about 15-20 cm and width is about 5-10 cm is used.

  As shown in FIG. 5, the cassette unit 30 includes a braking member 39 that presses against the electric wire drum 36 to brake the rotation of the electric wire drum 36, and a press-contact state of the braking member 39 against the electric wire drum 36 when the electric wire L is fed out. And a brake release mechanism 40 for releasing the brake. Specifically, the braking member 39 includes a press contact portion 48 that presses against the electric wire drum 36 and generates a frictional force with the electric wire drum 36. The pressure contact portion 48 is formed of a plate spring-like member having an inverted U-shape as a whole, one end side is fixed to the bottom plate 31 via the mounting member 47, and the other end side is extended along the side plate 32. The operation rod 46 is connected. The operation rod 46 is supported so as to be slidable in the longitudinal direction, and is between a position where the pressure contact portion 48 abuts on the electric wire drum 36 (braking position) and a position where it is separated from the electric wire drum 36 (release position). It is possible to slide. In addition, an elastic body (not shown) that biases in a certain direction (a direction in which the pressure contact portion 48 is in pressure contact with the electric wire drum 36) is attached.

  The brake release mechanism 40 includes a movable roller 51 that is rotatably supported on the operation rod 46. And since the electric wire L extended from the electric wire drum 36 is hung on the guide roller 41 via the movable roller 51, when pulling out the electric wire L from the cassette portion 30, a tensile force acts on the electric wire L. A force directed toward the electric wire drum 36 acts on the movable roller 51, and the operating rod 46 is displaced against the elastic force of the elastic body by the force. That is, when the pulling force when feeding the electric wire L becomes larger than a predetermined amount, the operating rod 46 is displaced and the locked state by the press contact portion 48 is released. In other words, the braking state is maintained and the rotation of the electric wire drum 36 is prevented until the electric wire L is fed out. However, when the electric wire L is fed out, the braking state is released and the electric wire drum 36 is rotated. The rotational load becomes lighter.

  The cassette unit 30 is provided with a guide roller 41 and a wrinkle removing unit 42 in the case unit 33. The wrinkle removing portion 42 is formed by combining a plurality of rollers, and corrects torsion wrinkles and bent wrinkles of the electric wires L by applying tension between the rollers. Further, the case portion 33 is provided with an electric wire guide portion 43 that feeds the electric wire L wound around the electric wire drum 36 from the tip portion of the case portion 33 in a certain direction. The wire guide portion 43 has a conical cylindrical shape, and the wire L can be projected straight from the tip.

  Furthermore, a columnar gripping portion 55 that is gripped when carrying the cassette portion 30 is provided on the front end side (the upper end side in FIG. 5) of the case portion 33 in the cassette portion 30. A bar code 56 storing the identification number assigned to each cassette unit 30 is attached. The identification number stored in the bar code 56 is associated with information on the type of the electric wire L, specifically, the color of the electric wire wound around each electric wire drum 36, the diameter of the electric wire, and the material of the covering material. Thus, the information regarding the type of the electric wire L can be recognized by reading the identification number with the information reading control means 86 (specifically, a barcode reader) described later. An IC chip may be provided instead of the barcode 56, and information regarding the type of the electric wire L may be stored so as to be writable and readable. In addition, when an IC chip receives radio waves such as high frequency, the radio waves are converted into electricity and stored, and when the power reaches a predetermined amount, information is written to the memory part of the IC chip or information is transmitted. It becomes possible to do.

  On the other hand, as shown in FIG. 1, the wire feeder 4 includes a feed mechanism main body 60, a guide unit 61, a movable table 66 on which the feed mechanism main body 60 and the guide unit 61 are placed, and an end side of the movable table 66. And a base portion 67 that is rotatably supported around the axis. The feed mechanism main body 60 is disposed between a predetermined take-out position A1 or take-out position A2 and the guide unit 61, and is supported by a movable base plate 62 slidably supported in the direction of arrow Y, and a movable base plate 62. And a pair of feed rollers 63 that rotate about a vertical axis on the movable base plate 62. The pair of feed rollers 63 are arranged with a predetermined distance apart and are fed while holding the electric wire L therebetween. Further, the pair of feed rollers 63 can be moved so as to approach and separate from each other, and by separating them, the electric wire L can be inserted / removed between the pair of feed rollers 63, and they are rotated close to each other. Thus, the electric wire L can be fed out.

  The movable base plate 62 is provided with a pair of second cutting blades 53 so as to cut the fed electric wire L based on a command transmitted from the terminal crimping device 2. According to this, even when replacing the electric wire L by cutting the electric wire L fed out from the electric wire feeding device 3 in the electric wire feeding device 3 which is the base side, the electric wire L already fed out is replaced with the electric wire drum 36. A process such as rewinding is not necessary, and the configuration in the cassette unit 30 can be simplified.

  Further, the movable base plate 62 is provided with a tip detection sensor 64 for detecting the tip position of the electric wire L. The electric wire L to be fed out is based on the time when the electric wire L is detected by the tip detection sensor 64. The length is measured (details will be described later).

  Furthermore, a protrusion (not shown) protruding toward the cassette portion 30 at the extraction position A1 or the extraction position A2 is formed on the distal end surface of the movable base plate 62, and the positioning roller can rotate at the distal end portion. It is supported. This positioning roller is inserted into a substantially triangular notch 57 (see FIG. 5) formed in the bottom plate 31 of the case portion 33 when the movable base plate 62 is slid to the cassette portion 30 side. Yes, the electric wire L protruding from the cassette unit 30 is made to face the pair of feed rollers 63 by sliding the cassette unit 30 at the extraction position A1 or the extraction position A2 to a normal position with the positioning roller 65 as a reference. Is possible. Although not shown, the electric wire supply device 3 has a lock that prevents the operation of the electric wire supply device 3, that is, the swiveling of the reception box portion 15 when the selected receiving box portion 15 moves to a predetermined extraction position. A device (eg, a positioning pin) is provided.

  As shown in FIG. 6, the guide unit 61 guides the electric wire L fed by the feed roller 63 of the feed mechanism main body 60 to the terminal crimping device 2. Specifically, a guide box 87 having a space through which the electric wire L passes between a pair of side walls, an upper guide member 88 that is fixed to the upper portion of the guide box 87 and extends in the feeding direction of the electric wire L, and an upper guide member 88 The lower guide member 89 is disposed below and extends in parallel with the upper guide member 88. In particular, the vicinity of the end of the lower guide member 89 on the outlet side (terminal crimping device 2 side) is rotatably supported by a shaft support member 90, and includes a linear guide position indicated by a solid line and an inclination indicated by a two-dot chain line. It is connected to a rotation drive source 98 (see FIG. 7) so as to be displaced between the guide positions. Here, the linear guide position is a position where the inlet side (feed mechanism main body 60 side) end of the lower guide member 89 is opposed to the feed roller 63 of the feed mechanism main body 60, and when displaced to this position, It becomes possible to guide the electric wire L fed from the feed roller 63 in a straight line. On the other hand, the inclined guide position is a position where the end portion on the inlet side of the lower guide member 89 is suspended and separated from the feed roller 63. When displaced to this position, the electric wire L fed from the feed roller 63 is fed to the feed guide. It is possible to bend between the roller 63 and the lower guide member 89. That is, it is possible to make the drawn-out electric wire L surplus between the feed roller 63 and the lower guide member 89.

  Further, as shown in FIG. 1, the feed mechanism main body 60 and the guide unit 61 are placed on a movable table 66 and configured to rotate within a predetermined range with respect to the base 67. Yes. That is, when the left side is turned to the left in FIG. 1 (shown by a solid line), the feed mechanism main body 60 faces the take-out position A1 (see FIG. 2) of the supply device main body 16 arranged on the left side, and the take-out position. It becomes possible to feed out the electric wire L from the receiving box part 15 arrange | positioned at A1. On the other hand, when it is rotated to the right side in FIG. 1 (indicated by a two-dot chain line), the feed mechanism main body 60 faces the take-out position A2 (see FIG. 2) of the supply device main body 16 arranged on the right side. It becomes possible to draw out the electric wire L from the receiving box part 15 arrange | positioned in the extraction position A2. A swing drive unit 68 (see FIG. 7) for rotating the movable table 66 is provided in the base 67, and the feed mechanism main body 60 and the guide unit 61 are moved by the swing drive unit 68. It is possible to oppose one of the selected extraction positions.

  Next, a functional configuration related to supply control of the electric wire L and its operation will be described with reference to FIG. Note that these functional configurations are realized by a CPU as a central processing unit, a ROM as a read-only memory, a RAM as a readable / writable memory, and the like. The terminal crimping device 2 is provided with an electric wire drum selecting means 70, and an electric wire drum corresponding to the electric wire L to be processed is selected from a plurality of electric wire drums 36. Specifically, since a number is assigned to each receiving box portion 15 in advance, one wire drum 36 is selected by specifying the number of each receiving box portion 15.

  The number of the receiving box portion 15 selected by the electric wire drum selection means 70 is transmitted to the electric wire supply device 3 by the transmission / reception control means 71. Then, in the wire supply device 3, the number is received by the transmission / reception control unit 83 and sent to the wire supply control unit 84. The electric wire supply control means 84 drives the motor 17 by the rotational position control means 85, and controls the receiving box portion 15 specified by the electric wire drum selection means 70 to be positioned at a predetermined take-out position. In particular, in this example, the two supply device main bodies 16 are provided adjacent to each other, and when one receiving box portion 15 is selected by the electric wire drum selection means 70, the receiving box portion 15 is supplied to either the left or right supply. By discriminating whether it is included in the apparatus main body 16 and driving the motor 17 in the corresponding supply apparatus main body 16, the selected receiving box portion 15 is controlled to be located at the take-out position. That is, when the receiving box portion 15 is included in the left supply device main body 16, the receiving box portion 15 is positioned at the extraction position A <b> 1, and when included in the right supply device main body 16, The receiving box portion 15 is positioned at the take-out position A2. Each motor 17 can be rotated forward and reverse, and the rotation direction is determined based on the positional relationship between the receiving box portion 15 currently located at the take-out position and the selected receiving box portion 15. That is, the rotation direction is determined so that the rotation angle is reduced. Further, the position of each receiving box 15 in each supply device main body 16 is recognized by an encoder (not shown) that detects the amount of rotation of the motor 17. Further, as shown in FIG. 2, when the selected receiving box portion 15 stops at the take-out position, any of the receiving box portions 15 corresponds to the four corners of the chain 13 formed by the sprocket 12. In particular, the corresponding receiving box portions 15 are extended at an angle of 45 °. Thereby, it is possible to reduce the rotational load when the chain 13 starts to rotate again, and to give a stable rotation to the chain 13. Here, the rotational position control means 85 corresponds to the movement control means of the present invention.

  In addition, the electric wire supply device 3 is provided with information reading means 86 (having a bar code reader) for reading the identification number from the bar code 56 attached to the case part 33 of the cassette part 30. Information about the electric wire drum (or electric wire) housed in the box portion 15 (specifically, the color of the electric wire, the diameter of the electric wire, the material of the covering material, and the initial length of the electric wire L wound around the electric wire drum 36) Is obtained based on the identification number recorded in the barcode 56 and information stored in advance in association with the identification number. This information is transmitted to the terminal crimping apparatus 2 via the transmission / reception control means 83 and displayed on the display by the electric wire display means 72 provided in the terminal crimping apparatus 2. The information about the electric wire drum 36 may be stored in association with the identification number every time the electric wire is wound on the electric wire drum 36, but only the initial length of the electric wire L changes each time, and other information. May be updated (that is, when the type of the electric wire L accommodated in each cassette unit 30 does not change), only the information regarding the initial length of the electric wire L may be updated.

  Further, in the terminal crimping device 2, the initial length storage means 74 for storing the initial length of the electric wire L read by the information reading means 86 and the length (cumulative) of each electric wire L subjected to the terminal processing are individually stored. The wire length measuring means 75 for measuring the length of the wire, the initial length of the wire L stored in the initial length storage means 74, and the length of each wire L measured by the wire length measuring means 75, respectively. And a remaining length calculating means 76 for calculating the remaining length of the electric wire L wound around the electric wire drum 36. That is, for each type of electric wire L, the used length is subtracted from the original length, and the remaining length is obtained. According to this, in the terminal crimping apparatus 2, it becomes possible to manage the remaining length wound around each electric wire drum 36 in a unified manner. In particular, in this example, when the calculated remaining length of the electric wire L becomes equal to or less than a predetermined amount, the notification control means 73 notifies the type of the electric wire L. For this reason, it becomes possible to make an operator recognize that the remaining amount has decreased, and it becomes possible to prepare a new electric wire drum 36 in advance.

  On the other hand, the wire feeding device 4 controls the feeding of the wire L by driving a transmission / reception control unit 77 that communicates with the transmission / reception control unit 71 of the terminal crimping device 2 and a motor 79 (stepping motor) that rotates the feed roller 63. An electric wire feed control means 78 and a cutting control means 54 for driving the second cutting blade 53 to cut the electric wire L are provided.

  By the way, when the electric wire drum 36 is replaced, the electric wire L is cut by the second cutting blade 53, but after the series of processing is completed in the terminal crimping device 2, that is, the electric wire L having a predetermined length is generated. In the case of cutting the electric wire L after being done, the electric wire L fed out between the terminal crimping device 2 and the electric wire supply device 3 remains as an end measure, resulting in wasted material. In particular, in the case of high-mix low-volume production, many end-scale electric wires L are generated, and there is a concern that material costs will increase significantly.

  Therefore, in the wire feeder 4 of this example, the required length recognition means 93 that recognizes the required length of the wire L generated in the terminal crimping device 2 and the wire L that has passed through the second cutting blade 53 via the feed roller 63. The cutting control means 54 recognizes the length of the electric wire L measured by the feeding length measuring means 94 by the required length recognizing means 93. When it matches the required length of the electric wire L, the second cutting blade 53 is operated to cut the electric wire L. For this reason, the already extended electric wire L is used in the terminal crimping apparatus 2, and it is possible to avoid the generation of the end length electric wire L. In addition, the required length of the electric wire L is recognized by receiving the information transmitted from the terminal crimping device 2 via the transmission / reception control means 77, and the length of the electric wire L passing through the second cutting blade 53 is determined by the motor. The length is measured by counting the number of steps in 79.

  Further, a tip detection sensor 64 for detecting the tip of the electric wire L is provided at a certain distance from the second cutting blade 53, and the length of the electric wire L measured by the feeding length measuring means 94 is Correction is performed based on the output of the tip detection sensor 64. Specifically, by subtracting the distance from the second cutting blade 53 to the tip detection sensor 64 from the length of the electric wire L measured after the tip of the electric wire L is detected, the second cutting blade 53 is The length of the passing electric wire L is recognized. According to this, even if there is variation in the length of the electric wires L protruding from the respective cassette units 30, it is possible to correct the initial length of the electric wires using the tip detection sensor 64, and the exact length The electric wire L can be generated.

  Further, the wire feed control means 78 rotates the feed roller 63 of the feed mechanism main body 60 at a constant speed regardless of the operation state of the roller 159 in the terminal crimping apparatus 2 until the wire L having a required length is fed out. The electric wire L is continuously fed out from the electric wire drum 36. That is, for example, when removing the covering material at the end of the electric wire L in the terminal crimping device 2 or when sending the electric wire L in the opposite direction, or when crimping the terminal to the end of the electric wire L, or the like. Even when the terminal processing is executed in a state where one end is interrupted, the wire L is continuously fed out from the wire drum 36 by rotating the feed roller 63 of the wire feeder 4 in a constant direction at a constant speed.

  The wire feeder 4 is provided with a guide direction switching control means 97, and when the tip of the wire L fed from the wire drum 36 is fed to the roller 159 of the terminal crimping device 2, the rotation drive source 98 is provided. And the lower guide member 89 is displaced from the linear guide position to the inclined guide position. Thereby, it becomes possible to make the electric wire L drawn | fed out between the feed roller 63 and the lower side guide member 89 surplus. In other words, even when the roller 159 of the terminal crimping device 2 is stopped or rotating in the reverse direction, the wire L can be continuously fed out by the feed roller 63 of the wire feeder 4 and is necessary. It is possible to quickly feed out the electric wire L having a long length.

  Further, the wire feeder 4 is provided with a take-out position switching means 69 for controlling the swing drive section 68, and when any one of the receiving box sections 15 is selected by the wire drum selection means 70, the receiving position switching means 69 is received. While selecting the supply device main body 16 including the box portion 15, the movable table 66 is turned to a predetermined position so that the tip of the feed mechanism main body 60 indicates the take-out position of the selected supply device main body 16. Thereby, it becomes possible to selectively feed out the electric wires from the two extraction positions.

  Thus, according to the electric wire processing system 1 of this example, the plurality of receiving box portions 15 are arranged in a loop along a predetermined vertical surface with the direction of the insertion port 23 aligned rearward. When the drive mechanism 11 is operated, it rotates on the vertical plane while maintaining its loop shape. For this reason, it becomes possible to move each electric wire drum 36 to extraction position A1 or extraction position A2. In addition, the plurality of cassette sections 30 can be regularly arranged and can be supported with a relatively simple structure. Therefore, it is possible to hold a large number of electric wire drums 36 in a narrow space, and consequently, the electric wire supply device 3 can be reduced in size. In particular, since it is arranged in a loop shape along a predetermined vertical plane, it becomes possible to displace each electric wire drum 36 in the horizontal direction and the vertical direction only by one drive mechanism 11 and is selected. It becomes possible to easily move the electric wire drum 36 to the predetermined extraction positions A1, A2. That is, it is not necessary to employ a complicated configuration in which a device that slides in the horizontal direction and a lifting device are combined, and the device can be manufactured at a relatively low cost and the device can be further downsized.

  Moreover, according to the wire processing system 1 of this example, since the plurality of receiving box portions 15 are connected to the endless chain 13 so as to be radial, by opening the back side of the receiving box portion 15, The cassette unit 30 can be inserted from the back side. For example, even when the front surface of the wire supply device 3 is closed with a decorative plate or the like, the wire drum 36 can be easily attached to and detached from the inside of each receiving box portion 15. It becomes possible.

  According to the wire processing system 1 of this example, an operation for moving the selected one receiving box portion 15 to a predetermined take-out position, and an operation for transferring the electric wire L extended from the cassette portion 30 to the terminal crimping device 2. Since a series of operations can be automated, the burden on the operator can be reduced and the electric wires to be processed can be surely and promptly supplied.

  Moreover, according to the electric wire processing system 1 of this example, since a pair of supply apparatus main bodies 16 are arranged in parallel, it becomes possible to distribute the number of the receiving box parts 15 required, and a rotational load becomes large. In addition, the inner diameter of the chain 13 can be prevented from becoming extremely large. Furthermore, it is possible to shorten the time required to move the required electric wire drum 36 to the take-out position, and as a result, the operating rate of the terminal crimping device 2 can be further increased. In particular, since two sets of supply device main bodies 16 having a loop shape are arranged adjacent to each other, the extraction positions A1 and A2 in the respective supply device main bodies 16 can be adjacent to each other. Further, a swing drive unit 68 for turning the wire feeder 4 is provided. When any one of the receiving box portions 15 is selected, one supply device body 16 including the receiving box portion 15 is selected. The tip of the wire feeding device 4 is turned so as to point to the take-out position of the selected supply device main body 16. Therefore, energy loss associated with moving the plurality of supply device main bodies 16 can be reduced, and the entire device can be further downsized. Moreover, even when the electric wire L is being fed out from the one supply device main body 16 side, when the electric wire L to be fed out is included in the other supply device main body 16 side, the feeding operation is completed. It is possible to prepare the next electric wire L, that is, to move the receiving box portion 15 in which the electric wire L is accommodated to the take-out position, and to further reduce the setup time associated with the exchange of the electric wire L. it can.

  Moreover, according to the electric wire processing system 1 of this example, the electric wire feeder 4 is provided with the second cutting blade 53 arranged to face the take-out position, and the information transmitted from the terminal crimping device 2 is Based on the operation. For this reason, when exchanging the electric wire L used by the terminal crimping apparatus 2, the drawn-out electric wire L can be cut | disconnected by the root side, and the process of rewinding the electric wire L to the electric wire drum 36 becomes unnecessary. That is, it is possible to simplify the configuration of the electric wire supply device 3.

  Moreover, according to the electric wire processing system 1 of this example, since the supply device main body 16 is provided with the plurality of receiving box portions 15, it is possible to supply different types of electric wires from the supply device main body 16 as needed. Become. In particular, since it is a cassette type, the work of attaching the electric wire drum 36 to the supply device main body 16 becomes extremely easy. Moreover, since the electric wire L is drawn out from the determined position in a fixed direction, the electric wire L can be reliably held by the electric wire feeder 4, and smooth delivery becomes possible. Further, when replacing the electric wire drum 36, the cassette portion 30 is taken out from the receiving box portion 15, and the electric wire drum 36 accommodated in the case portion 33 is replaced. In addition, even when the electric wire drum 36 is being replaced, the electric wire L can be continuously supplied from the receiving box portion 15 in which the other electric wire drum 36 is accommodated. In addition, since a plurality of cassette sections 30 can be regularly arranged and supported with a relatively simple structure, a large number of wire drums 36 can be held even in a narrow space, and the terminal crimping device 2 can be downsized. Is possible.

  Further, according to the wire processing system 1 of the present example, the wire L protruding from the wire drum 36 is sandwiched between the pair of feed rollers 63, and the pair of feed rollers 63 is rotated in opposite directions, whereby the wire L Is fed from the electric wire drum 36, and the fed electric wire L is guided toward the terminal crimping device 2 by passing through the guide unit 61. For this reason, it becomes possible to deliver the front-end | tip of the electric wire L to the terminal crimping apparatus 2 with a comparatively simple structure. In particular, the wire feeder 4 recognizes the required length of the wire L generated in the terminal crimping device 2 and measures the length of the wire L passing through the second cutting blade 53 to measure the length of the wire. When the length of L matches the required length of the recognized wire L, the second cutting blade 53 is operated to cut the wire L. For this reason, the already drawn-out electric wire L is used in the terminal crimping apparatus 2, and it is possible to avoid the generation of the end-sized electric wire L.

  Further, according to the wire processing system 1 of this example, the terminal crimping device 2 is provided with the roller 159, but the feed roller 63 in the wire feeding device 4 is independent of the operating state of the roller 159 in the terminal crimping device 2. In order to feed out the electric wire L from the electric wire drum 36, for example, when removing the covering material at the end of the electric wire L in the terminal crimping device 2, when the electric wire L is sent in the reverse direction, or the terminal is crimped to the end of the electric wire L. Even when the terminal processing is executed in a state where the feeding of the electric wire L is interrupted once, the electric wire L is continuously fed from the electric wire drum 36 by rotating the feeding roller 63 of the electric wire feeding device 4 in a certain direction. Let them go out. Therefore, it becomes possible to feed out the required length of the electric wire L earlier than when the processing of the electric wire L is finished in the terminal crimping device 2, and even while the electric wire is being processed in the terminal crimping device 2, In the supply device 3, preparation for feeding out the electric wire to be processed next, specifically, an operation of moving the selected electric wire drum 36 to a predetermined extraction position can be performed. In this case, the setup time is greatly reduced, and the operating rate in the terminal crimping device 2 can be further increased. In particular, when the tip of the electric wire L fed from the electric wire drum 36 is sent to the roller 159 of the terminal crimping device 2, the rotational drive source 98 is driven, and the lower guide member 89 is displaced from the linear guide position to the inclined guide position. Then, the electric wire L fed from the feed roller 63 can be bent between the feed roller 63 and the lower guide member 89. For this reason, even when the roller 159 of the terminal crimping device 2 is stopped or rotating in the reverse direction, the electric wire L can be continuously fed out by the feed roller 63 of the wire feeding device 4, which is necessary. It becomes possible to quickly feed out the electric wire L having a length.

  In addition, according to the wire processing system 1 of this example, the twisting portion 42 or the bending portion of the electric wire L is corrected by the scooping portion 42 provided in the case portion 33, so that the substantially linear electric wire L is connected to the electric wire guide portion. 43, and by extension, linearity can be imparted to the extending direction of the electric wires protruding from the case portion 33. Therefore, the delivery of the electric wire L can be made more reliable.

  In addition, according to the wire processing system 1 of the present example, since the braking member 39 that brakes the rotation of the wire drum 36 is provided, the malfunction due to the rotation of the wire drum 36 caused by the movement of the receiving box portion 15 or the like, That is, the problem that the electric wire L is drawn out naturally, the electric wire L bends in the case portion 33, or the electric wire L is removed from the electric wire guide portion 43 can be solved. In addition, since the brake release mechanism 40 operates with respect to the cassette portion 30 at the take-out position, the electric wire drum 36 can be rotated without increasing the rotational load, and the electric wire L can be easily moved with a relatively small tensile force. It becomes possible to let it go out. In particular, since the braking state is released by using the pulling force of the electric wire L, the braking and releasing operations can be automated.

  Furthermore, according to the electric wire processing system 1 of the present example, the cassette unit 30 inserted into the receiving box portion 15 from the insertion port 23 is locked by the locking member 24, so that the cassette portion 30 is detached from the receiving box portion 15. Separation can be prevented and it can be moved in a stable state.

  Then, the electric wire supply apparatus 201 which is 2nd embodiment of this invention is demonstrated based on FIG.8 and FIG.9. FIG. 8 is a front view showing the configuration of the wire supply device 201, and FIG. 9 is a perspective view showing the configuration of the wire supply device 201. In the drawings, the same components as those of the wire supply device 3 of the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

  The electric wire supply device 201 of this example includes three sets of supply device main bodies 16 and is slidable in the horizontal direction with respect to the electric wire feeder 4. That is, in the electric wire supply device 3 of the first embodiment, the electric wire feeding device 4 is movable with respect to the two sets of the supply device main bodies 16 fixed. However, in the electric wire supply device 201 of this example, the electric wire supply device 201 is fixed. The three sets of supply device main bodies 16 are simultaneously slid in the horizontal direction with the take-out position as the center so that the supply device main bodies 16 face each other as necessary. Specifically, a gantry 202, a movable base member 203 that is supported so as to be slidable in the horizontal direction with respect to the gantry 202, and on which three sets of supply device bodies 16 are placed, and a horizontal direction that moves the movable base member 203 in the horizontal direction. And a drive source 204. In addition, each supply apparatus main body 16 is like the supply apparatus main body 16 of the first embodiment, and a plurality of receiving box portions 15 arranged in a loop shape along a vertical plane parallel to the front surface of the wire supply apparatus 3; A drive mechanism 11 for moving these receiving box portions 15 is provided.

  Moreover, in this electric wire supply apparatus 201, it is discriminate | determined in which supply apparatus main body 16 the receiving box part 15 selected as supply object is contained, and the supply apparatus main body 16 has opposed the electric wire feeder 4. FIG. In the case where the receiving box portion 15 is rotated only by the drive mechanism 11 to the take-out position, while the supply device main body 16 including the selected receiving box portion 15 is not opposed to the wire feeding device 4. The movable base member 203 is moved in the horizontal direction by the horizontal drive source 204 so as to face the wire feeder 4, and the receiving box portion 15 is rotated by the drive mechanism 11 to the take-out position. In this way, by sliding the plurality of supply device main bodies 16 in the horizontal direction around the wire feeder 4, the electric wires L are fed out from all the wire drums 36 distributed and provided in the plurality of sets of supply device main bodies 16. It becomes possible.

  As described above, the two embodiments for carrying out the present invention have been described. However, the present invention is not limited to these embodiments, and within the scope not departing from the spirit of the present invention as shown below. Various improvements and design changes are possible.

  That is, in the above-described two embodiments, the drive mechanism 11 for turning the plurality of receiving box portions 15 is configured by the plurality of sprockets 12 and the endless chain 13 wound around them. A plurality of receiving box portions 15 may be fixedly attached to the base plate standing upright and rotated together with the base plate. However, if the chain 13 is used as in this example, the base plate does not rotate, so that the plurality of receiving box portions 15 can be arranged along a substantially rectangular loop, and the disc-shaped base plate It is possible to use the installation space more efficiently than those that rotate (that is, those that are cylindrical in appearance).

  Moreover, in said two embodiment, the some receiving box part 15 shows what is arranged in the loop form along the vertical surface parallel to the front (surface by the side of the terminal crimping apparatus 2) of the electric wire supply apparatus 3. However, it may be arranged in a loop along a vertical plane parallel to the side surface of the wire supply device 3.

  In the two embodiments described above, the second cutting blade 53 is provided in the wire feeder 4, but the wire feeder 3 may be provided.

  Further, in the above two embodiments, the wire L is fed out from the opposite side of the insertion port 23, but the electric wire L may be fed out from the surface on the insertion port 23 side.
