Description

  The present invention relates to a movable wire feeder that selectively feeds only a desired wire from a plurality of wire reels wound with different wires.

  The wire harness is configured by bundling various electric wires having different wire diameters, colors of covering materials, and the like. In order to manufacture this wire harness by automation, it is necessary to extract a desired wire from a plurality of wire reels around which different types of wires are wound, and to obtain a fixed-length wire having a predetermined length. Conventionally, there is an electric wire feeder as a device that enables such an operation automatically.

  As shown in FIG. 12, the wire feeder a disclosed in Patent Document 1 includes a servo motor c installed on a frame b and a pair of endless timing belts d and d that rotate by the rotation of the servo motor c. And a plurality of guide nozzles f (f1, f2,...) Installed between a pair of endless timing belts d and d and passing electric wires e (e1, e2,. .. F8) and a pair of feed rolls g, g for drawing the electric wire e1 from the guide nozzle f1.

  The pair of endless timing belts d and d are provided in a square shape via a pulley shaft h. The guide nozzles f are disposed at regular intervals between the endless timing belts d and d, and are intermittently rotated by the rotation of the endless timing belt d. The feed roll g is a flat rotating plate and feeds a necessary length by sandwiching the electric wire e1 between the pair of feed rolls g. The electric wire e1 that has passed through the electric wire feeding device a proceeds to an electric wire cutting device, an electric wire conveying device, an electric wire terminal peeling device, etc. (not shown). The guide nozzles f1 to f8 correspond to the wire reels k (k1, k2,... K8) placed on the wire shelf j, and the wire e is supplied directly from the wire shelf j to the wire feeder a.

The endless timing belt d is rotated by the rotation of the servo motor c, and the guide nozzle f1 having a desired electric wire (for example, e1) is moved to a predetermined position (position where the feed roll g can send out the electric wire e1). Then, the electric wire e1 is pulled out by a predetermined length by the rotation of the feed roll g. At this time, the other electric wires e2 to e8 are pulled from the electric wire shelf j by the rotation of the endless timing belt d, and are loosened between the electric wire feeder a and the electric wire shelf j. By repeating the above, it is possible to draw out a desired wire one after another.
JP-A-9-223419 (FIG. 4)

  However, in the above-described conventional wire feeder a, the guide nozzle f moves relative to the wire reel k. Therefore, when handling a large number of wires (for example, 100), each time the endless timing belt d is rotated, There was a possibility that the electric wires would be in contact with each other and rubbed, and the electric wires might be damaged. This was particularly noticeable when wires that were relatively susceptible to rubbing, such as non-halogen specifications, were targeted for delivery. Further, when the rotational speed of the endless timing belt d is increased, the endless timing belt d is bent (swelled) outward, and the guide nozzle f contacts the feed roll g and the like. It was. Furthermore, since the guide nozzle f contacts the feed roll g and the like, there is a problem that the rotational speed of the endless timing belt d cannot be increased, and a desired electric wire cannot be selected and sent out at high speed.

  The present invention has been made in view of the above circumstances, and can prevent contact and rubbing between wires due to movement of the guide nozzle relative to the wire reel, and contact between the guide nozzle and the feed roll, and the like. An object of the present invention is to provide a movable electric wire feeder capable of high-speed selective feeding of electric wires.

In order to achieve the above object, a movable wire feeder according to the present invention is a movable wire feeder that draws a desired wire from a plurality of wire reels wound with different types of wires, each wire being An electric wire support base for holding a plurality of electric wires drawn from the reel in parallel at predetermined intervals, a moving base that is reciprocated in a direction orthogonal to the electric wires held on the electric wire support base, and a predetermined interval provided on the moving base A pair of electric wire feeding means for holding the arbitrary one electric wire by being moved close to each other and rotating the same synchronously to send the electric wire in the drawing direction, and provided on the moving table. It is characterized by comprising length measuring means for measuring the amount of electric wire delivered and electric wire cutting means for cutting the electric wire that is provided on the moving table and sent out through the electric wire feeding means.

In this movable electric wire feeder, after moving the moving base to the position of the electric wire, only the desired electric wire can be sent out from a plurality of different electric wires by synchronously rotating while holding the electric wire between a pair of electric wire feeding means It becomes.
Therefore, it is possible to selectively feed and cut any wire without moving the wire reel and the wire support base relative to each other. For example, even a wire that is relatively resistant to rubbing, such as a non-halogen specification, is not damaged. Fast selection and delivery are possible.

  In the movable wire feeding device of the present invention, the wire support base is provided with a plurality of parallel support bars in a direction orthogonal to the wire direction, and the support bars have a plurality of axes whose directions are the same as those of the wires. An electric wire nozzle is provided in parallel, and the electric wire is inserted and held in each electric wire nozzle.

In this movable electric wire feeder, the electric wire drawn out from the electric wire reel is held so as to be able to pass through the electric wire nozzle of the electric wire support base, the holding position of the electric wire support base with respect to the electric wire reel becomes constant, and The slack is less likely to occur between
Therefore, the drawing load at the time of drawing the electric wire by the electric wire feeding means is stabilized, and the accuracy of the electric wire feeding amount is increased.

  Furthermore, the movable electric wire feeder of the present invention is characterized in that the moving table reciprocates on the same plane.

  In this movable electric wire feeder, the moving table moves on the same plane, so the moving mechanism of the moving table becomes simpler and the electric wire feeding operation is faster than when the moving table moves up and down, left and right, for example. And it will be certain.

  The movable electric wire feeder of the present invention includes a plurality of block bodies including a pair of block bodies that are provided on the moving base and approach and separate from each other with the electric wires interposed therebetween, and a drive pulley that is provided on the block bodies. It consists of an endless belt for feeding an electric wire stretched around a pulley.

In this movable electric wire feeder, the planar peripheral circuit of the endless belt for electric wire feeding stretched between at least a pair of pulleys becomes the electric wire clamping surface.
Accordingly, the electric wires are clamped by the pair of electric wire clamping surfaces, and the electric wire feeding endless belts are synchronously rotated in the reverse direction, so that the electric wires are fed in the drawing direction. Thereby, compared with the case where a pair of clamping rollers etc. are used, a contact area with an electric wire can be ensured large, it becomes difficult to produce a slip, and the precision of a feeding amount increases.

  In the movable electric wire feeder according to the present invention, the movable base is provided with a pair of fixed pulleys located outside the block body in the direction of separation, and the pair of fixed pulleys and the coaxial pulley side of the drive pulley A driving endless belt stretched around a pulley is stretched between a pair of the block bodies in a part of the peripheral circuit, and a first belt path in a direction along the approaching / separating direction between the blocks, And a pair of second belt paths extending between the block and the pair of fixed pulleys in a direction along the approaching / separating direction of the block.

In this movable electric wire feeder, when the pair of block bodies are moved away from each other, the length of the first belt path across the pair of block bodies is increased. Moreover, a pair of block body will approach an outer fixed pulley by separating.
Accordingly, the length of the second belt path extending between each block body and the fixed pulley is reduced by the same amount. That is, the circumferential circuit length of the driving endless belt does not change even when the block body approaches or separates, and the tension does not vary. Thereby, even when the block body is moved, load fluctuation due to tension fluctuation does not occur in the movement mechanism of the block body, and even when a small-diameter electric wire or a large-diameter electric wire is clamped, the clamping force is always constant.

  Furthermore, the movable electric wire feeder according to the present invention is characterized in that the electric wire feeder is disposed between the pair of electric wire nozzles.

  In this movable wire feeder, since the wire feeder is disposed between the pair of wire nozzles, it is possible to always hold a straight wire without slack, and the accuracy of the feed amount by the wire feeder can be increased. Rise.

  In the movable electric wire feeder according to the present invention, a driving source for reciprocating the moving table is provided outside the moving table, and the moving table includes power transmission means connected to the driving source. It is characterized by being reciprocated through.

  In this movable electric wire feeder, since the drive source is provided outside the moving table, the moving table can be reduced in weight, and the inertial force is reduced. Miniaturization is possible.

According to the movable electric wire feeder of the present invention, various electric wires drawn out from a plurality of electric wire reels are held in parallel by an electric wire support base, and a moving base that is reciprocated in an orthogonal direction with respect to the electric wire is provided. Since the moving base is provided with a pair of electric wire feeding means for sandwiching and feeding the electric wire, after moving the moving base to the position of the desired electric wire, by synchronously rotating while holding the electric wire between the pair of electric wire feeding means, Only a desired electric wire can be sent out from a plurality of different electric wires.
Therefore, any wire can be sent out and cut without relative movement between the wire reel and the wire support base, so even a wire that is relatively resistant to rubbing, such as a non-halogen specification, can be fast without causing damage. You can select and send it out.

  In the present embodiment, the case where the movable electric wire feeder 100 is provided in the regular electric wire machine 300 of the electric wire machine 200 will be described as an example. Prior to the description of the movable electric wire feeder 100, an outline of the electric wire processing machine 200 will be described. The electric wire processing machine 200 is for manufacturing a wire harness configured by mixing various electric wires, and is formed by connecting the following processing machines. That is, the electric wire processing machine 200 is configured by arranging a fixed-length electric wire processing machine 300, a crimping machine 400, and a terminal-attached electric wire transfer machine 500 in a horizontal row. A wire feeder 600 shown in FIG. 2 is provided behind the fixed wire processing machine 300, a connecting machine (not shown) is provided at the rear of the transfer machine 500, and a housing mounting machine (not shown) is provided behind the connecting machine. A housing feeder (not shown) and a harness molding machine (not shown) are arranged on both the left and right sides, respectively.

  In the fixed wire processing machine 300, in order to produce a terminal-attached electric wire that constitutes a wire harness, the length is measured while a long electric wire is pulled out and cut into a predetermined length. In the electric wire feeder 600, a large number of electric wire reels 21 having different electric wire diameters and coating colors are dispersedly arranged in a plurality of electric wire storage shelves 23. The electric wires 25 are electric wires provided with guides 27 corresponding to the electric wires 25. It is supplied from the pre-feeder 29 to the movable electric wire feeder 100.

  Each electric wire 25 cut to a predetermined length by the fixed wire processing machine 300 is held and fixed at a predetermined pitch at both ends by a first electric wire conveying device (not shown) provided on the gantry 31, and is U-shaped. Are intermittently transferred in a bent state and reach the next caulking machine 400.

  In the crimping machine 400, all processes from trimming of the terminal portion of each electric wire 25 to terminal crimping are performed. The caulking machine 400 is provided with a second electric wire conveying device (not shown), and the group of electric wires 25 intermittently fed by the first electric wire conveying device is sequentially transferred to the second electric wire conveying device by the electric wire transfer hand 37 shown in FIG. It is transferred to. In the electric wire transfer hand 37, two pairs of claws 37a and 37a for holding the electric wire 25 are formed with a predetermined gap d therebetween. As for the electric wire 25 pinched by the electric wire transfer hand 37, this gap | interval d part is pinched | interposed into an electric wire clip. At this time, the electric wire 25 group is held at the same arrangement pitch as before. In the crimping machine 400, a trimming device 41, a peeling device 43 and an image sensor 45 are arranged in accordance with the arrangement pitch of the electric wires 25, and a plurality of terminal crimping machines 47a for crimping terminals of different product numbers, 47b, 47c, 47d, 47e, 47f, 47g, and 47h (hereinafter also collectively referred to as 47) are arranged in parallel.

  In the trimming device 41, the terminal of the electric wire 25 is trimmed, and the length from an electric wire clip (not shown) for temporarily holding the electric wire 25 becomes constant. Then, after stripping (striping) the end of the electric wire in the peeling device 43 and confirming the strip state of the electric wire 25 (the length of the exposed conductor, etc.) by the image sensor 45, a predetermined terminal crimping machine A terminal 49 (see FIG. 4) of a desired size is crimped by 47.

  The first and second electric wire conveyance devices have the same structure, and a plurality of electric wire clips are arranged in parallel at a predetermined pitch on an endless timing belt (not shown). The electric wire clip has a pair of clamps formed with an insertion guide slope on the upper end, and is urged in the closing direction by a spring.

  In the transfer machine 500, the reversing transfer hand 51 that can rotate and the necessary reversal of the terminals 49, the arrangement of the electric wire 25 group on the timing belt is changed and transferred to the electric wire clamp 53 shown in FIG. And stock.

  The electric wire clamp rod 53 is formed by arranging an electric wire clip 57 including a pair of sandwiching elements 57a and 57a in parallel with the long support rod 55 in the same manner as the electric wire clip. FIG. 4B shows a case where the group of electric wires 25 is reversed and locked to one electric wire clamp 53 including rearrangement. As is clear from the comparison with FIG. 4A, the ends of each electric wire 25 are grouped into several groups corresponding to the connectors 59, 61, 63 to be mounted, and the actual wire harness is arranged. It is close.

  As shown in FIG. 5, the movable wire feeder 100 according to the present invention is provided in a fixed wire machine 300 of the wire machine 200 configured as described above. The movable electric wire feeder 100 draws out a desired electric wire 25 from a plurality of electric wire reels 21 wound with different types of electric wires 25, and cuts the electric wire 25 to a predetermined length by cutting it at a predetermined length.

  The movable electric wire feeder 100 is mainly composed of an electric wire support 71 shown in FIG. 6, a moving base 73, a pair of electric wire feeders 75 and 75 shown in FIG. 8, and an electric wire cutting means 77 shown in FIG. Prepare as an element. The electric wire support 71 holds a plurality of electric wires 25 drawn from the electric wire reels 21 in parallel at predetermined intervals. As shown in FIG. 6, a plurality of parallel support bars 79a, 79b, 79c, 79d, which are orthogonal to the direction of the electric wires, are arranged in parallel on the wire support base 71, and the support bars 79a, 79b, 79c, 79d have axes. A plurality of wire nozzles 81a, 81b, 81c, 81d in the same direction as the wire 25 are arranged in parallel. Each electric wire 25 is inserted and held in a corresponding electric wire nozzle 81a, 81b, 81c, 81d.

  In the present embodiment, four support bars 79a, 79b, 79c, 79d are juxtaposed, and electric wire nozzles 81a, 81b, 81c, 81d are fixed to the respective support bars 79a, 79b, 79c, 79d. Accordingly, one electric wire 25 is held by the electric wire support base 71 through the four electric wire nozzles 81a, 81b, 81c, 81d. Thus, the electric wire 25 drawn out from the electric wire reel 21 is held by the electric wire nozzles 81a, 81b, 81c, 81d of the electric wire support base 71, so that the holding position of the electric wire support base 71 with respect to the electric wire reel 21 becomes constant. And as shown in FIG. 2, slack becomes difficult to produce between the electric wire reel 21 and the electric wire support stand 71. FIG. Accordingly, the drawing load at the time of drawing the electric wire by the electric wire feeding means described later is stabilized, and the accuracy of the electric wire feeding amount is increased.

  The moving base 73 is configured to reciprocate in the orthogonal direction with respect to the electric wire 25 held by the electric wire support base 71. That is, the moving table 73 reciprocates on the same plane. In this way, the moving base 73 moves on the same plane, so that the moving mechanism becomes simpler and the selective feeding operation of the electric wire 25 is fast and reliable as compared with the case where the moving base 73 is moved up and down, left and right, for example. Become.

  As shown in FIG. 7, the moving table 73 is supported so as to be able to reciprocate via a linear guide 83 provided on the gantry 31. The moving table 73 is provided with a drive source for reciprocating movement outside the moving table 73. The drive source provided outside is connected to the moving table 73 through power transmission means. In the present embodiment, as shown in FIG. 1, an electric motor 85 as a drive source is fixed to the mount 31, and the drive shaft of the electric motor 85 is connected to a drive shaft 87 which is a power transmission means via a speed reducer or the like. It is connected. A screw is formed on the drive shaft 87, and this screw is screwed into a screwing means (nut or the like) 89 fixed to the moving table 73.

  Therefore, when the drive shaft 87 is rotated forward and backward by forward and reverse rotation of the electric motor 85, the moving base 73 is reciprocated through the screwing means 89 screwed to the drive shaft 87. As described above, since the drive source is provided outside the moving table, the moving table 73 can be reduced in weight and the inertial force can be reduced. Therefore, the driving source and the linear moving mechanism can be reduced in size. It becomes possible. In addition, as a drive mechanism provided outside for moving the moving base 73, a linear drive mechanism having a ball screw, a linear drive mechanism using a belt or a chain, a linear motor, or the like can be used.

  The moving table 73 is provided with a pair of wire feeding means 75 and 75 shown in FIG. The wire feeding means 75 and 75 are arranged at a predetermined interval in the vertical direction, while holding the arbitrary one electric wire 25 by moving close to each other and rotating synchronously to draw out the electric wire 25 (see FIG. 5 in the left-right direction).

  As shown in FIG. 8, the pair of wire feeding means 75 and 75 is disposed between the wire nozzles 81a and 81b. By arranging the wire feeding means 75, 75 between the pair of wire nozzles 81a, 81b, it becomes possible to always hold the straight wire 25 without slack, and the amount of feeding by the wire feeding means 75, 75 can be reduced. The accuracy is increasing.

  In the present embodiment, as shown in FIG. 9, the electric wire feeding means 75, 75 includes a pair of block bodies 91, 93 that are provided on the moving base 73 and that are separated from each other with the electric wire 25 interposed therebetween, and the block bodies 91, 93. And an endless belt 101 for feeding an electric wire stretched around a plurality of pulleys 97 and 99 including a drive pulley 95. The wire feeding endless belt 101 forms a triangular peripheral circuit by the drive pulley 95 and the pulleys 97 and 99.

  In the endless belt 101 for electric wire feeding, a planar peripheral circuit stretched between at least a pair of pulleys 95 and 97 serves as an electric wire clamping surface 101a. Therefore, the electric wire 25 is clamped by the pair of electric wire clamping surfaces 101a and 101a, and the electric wire feeding endless belts 101 are synchronously rotated in the opposite directions, so that the electric wires 25 are fed in the drawing direction. Thereby, compared with the case where a pair of clamping rollers etc. are used, for example, a large contact area with the electric wire 25 can be ensured, slipping is less likely to occur, and the accuracy of the feed amount is increased.

  The pair of block bodies 91 and 93 includes a link mechanism 105 configured to have a tension spring 103 shown in FIG. The pair of block bodies 91 and 93 are urged in the approaching direction by the link mechanism 105. The pair of block bodies 91 and 93 is provided with an air cylinder 105 shown in FIG. 7 that separates the block bodies 91 and 93 in the separating direction. Accordingly, the pair of block bodies 91 and 93 can be held in a separated state so that the electric wire 25 can be inserted against the urging force of the link mechanism 105.

  The length measuring rollers 107 and 107 shown in FIG. 10 are provided in the respective block bodies 91 and 93, and the length measuring rollers 107 and 107 move the block bodies 91 and 93 closer to each other so that the electric wire 25 is sandwiched between them. It is designed to rotate in synchronization with the feed. As a result, the length of the wire 25 that is nipped by the endless belts 101 and 101 and fed out is measured by the length measuring rollers 107 and 107.

  Further, as shown in FIG. 10, a plurality of guide roller groups 109 and 111 are provided on the rear end block bodies 91 and 93 of the block bodies 91 and 93, and the guide roller groups 109 and 111 are the length measuring rollers 107 and 107, respectively. It is possible to straighten the electric wire 25 introduced into the straight line.

  Driving force is input to the driving pulley 95 of the wire feeding means 75 and 75 by coaxial input side pulleys 113 and 113 shown in FIG. 7 provided on the surface opposite to the endless belt 101 for feeding the wire. The moving table 73 is provided with a pair of fixed pulleys 115, 115 positioned outside the block bodies 91, 93 in the direction of separation. In addition, the block bodies 91 and 93 are provided with a pair of pulleys 121 and 121 and a pair of pulleys 123 and 123 that are arranged on a virtual line in the approaching / separating direction. In the figure, reference numeral 125 denotes a path change pulley.

  A drive endless belt 127 is stretched around the coaxial input side pulleys 113 and 113, the fixed pulleys 115 and 115, the pulleys 121 and 121, the pulleys 123 and 123, and the path changing pulley 125. One of the pair of fixed pulleys 115 and 115 is connected to an output shaft of a drive source (not shown).

  Here, the driving endless belt 127 is stretched between a pair of block bodies 91 and 93 in a part of its peripheral circuit, and the first belt path in the direction along the approaching / separating direction of the block bodies 91 and 93. 131 and a pair of second belt paths 133 and 135 that are stretched between the respective block bodies 91 and 93 and the pair of fixed pulleys 115 and 115 in a direction along the approaching / separating direction of the block bodies 91 and 93. is doing.

  In the block bodies 91 and 93 in which the driving endless belt 127 is stretched, when the pair of block bodies 91 and 93 are moved away from each other, the first belt path 131 across the pair of block bodies 91 and 93 Length increases. Moreover, a pair of block bodies 91 and 93 will approach the outer fixed pulleys 115 and 115 by separating. Accordingly, the lengths of the second belt paths 133 and 135 extending between the respective block bodies 91 and 93 and the fixed pulleys 115 and 115 are reduced by the same amount.

  In other words, the circumferential circuit length of the driving endless belt 127 does not change even when the block bodies 91 and 93 approach and leave, and the tension does not vary. As a result, even when the block bodies 91 and 93 are moved, the load fluctuation due to the tension fluctuation does not occur in the moving mechanism (link mechanism 105, air cylinder 105) of the block bodies 91 and 93, and the small-diameter electric wire or the large-diameter electric wire is pinched. Even in this case, the clamping force is always constant.

  The moving table 73 is provided with a wire cutting means 77 in front of the wire feeding means 75, 75. The electric wire cutting means 77 has a base portion 77a through which the electric wire 25 is inserted, and an opening / closing portion 77c fixed to the base portion 77a through a hinge 77b. The base 77a and the opening / closing part 77c are provided with a clamp 77d and a cutter 77e. The electric wire 25 sandwiched between the clamps 77d is sent out by forming the loop portion 25a by being led out from the base portion 77a by the electric wire feeding means 75 and 75 when the opening / closing portion 77c is opened. The fed electric wire 25 is held by both ends of the loop portion 25a by the electric wire transfer hand 37 and cut by the cutter 77e, and at the same time the clamp is released and transferred. The electric wire cutting means 77 to which the electric wire 25 has been transferred closes the opening / closing portion 77c, holds the tip of the electric wire 25 fed for a predetermined length by the clamp 77d, and repeats the same operation as described above.

  Therefore, according to the movable electric wire feeder 100 configured as described above, after moving the moving base 73 to the position of the electric wire 25, the electric wire 25 is synchronously rotated while being sandwiched between the pair of electric wire feeders 75 and 75. Thus, only a desired electric wire 25 can be sent out from a plurality of different electric wires 25. Therefore, it is possible to selectively feed and cut an arbitrary electric wire 25 without relatively moving the electric wire reel 21 and the electric wire support base 71. For example, even an electric wire that is relatively resistant to rubbing such as a non-halogen specification is damaged. Without making it possible, high-speed selection and delivery are possible.
