TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wire feeder, and more particularly, to a wire feeder that sends out a wire such as an electric wire by a pair of rotating bodies.
[0002]
[Prior art]
2. Description of the Related Art As a terminal crimping device for attaching a crimp terminal to the end of an electric wire, there is known a terminal crimping device including a crushing member that moves up and down by a power mechanism and a base on which a concave anvil is formed. According to this, the tip of the electric wire is inserted into the crimp terminal sent to the anvil of the base and crushed by the crushing member, so that the crimp terminal is attached to the tip of the electric wire.
[0003]
Also, an automatic wire feed mechanism for automatically feeding the tip of the wire into the crimp terminal before crushing the crimp terminal, and automatically moving the wire to which the crimp terminal is attached to a predetermined position after crushing the crimp terminal, There is also known a terminal crimping apparatus provided with a cutting mechanism for automatically cutting an electric wire and removing a covering material at an end of the electric wire.
[0004]
Here, the electric wire feeding mechanism 50 includes, for example, an electric wire intake guide 51, a pair of rotating bodies 52 and 53, a guide pipe 54, a circular rotating plate 55, and the like, as shown in FIG. The rotating bodies 52 and 53 are driven by a sending driving means (not shown), and rotate in opposite directions to send out the electric wire L inserted between the rotating bodies 52 and 53 while measuring the length. That is, the electric wire L taken in through the electric wire taking-in guide 51 is sent while being sandwiched between the pair of rotating bodies 52 and 53, and inserted into the guide pipe 54. The guide pipe 54 is a cylindrical member, and regulates the feeding direction of the inserted wire L. That is, when the electric wire L is fed into the cutting mechanism, the circular rotary plate 55 is rotated so that the tip of the guide pipe 54 faces the cutting mechanism, and the electric wire L is attached to the crimp terminal mounted on the base anvil. Is inserted, the circular rotary plate 55 is rotated so that the tip of the guide pipe 54 faces the anvil side. That is, by rotating the circular rotating plate 55 on which the electric wire intake guide 51, the pair of rotating bodies 52 and 53, and the guide pipe 54 are mounted within a predetermined angle by rotating means (not shown) having a motor or the like. The direction of the guide pipe 54 is arbitrarily switched between a direction in which the tip of the guide pipe 54 faces the anvil and a direction in which the tip faces the cutting mechanism.
[0005]
When the electric wire L is fed into the cutting mechanism by the electric wire feeder, the electric wire L is inserted between the upper blade and the lower blade of the cutting mechanism. In the cutting mechanism in which both the upper blade and the lower blade can be displaced in the vertical direction, the electric wire L can be cut vertically by displacing the upper blade and the lower blade after feeding the electric wire L. However, in the cutting mechanism in which the lower blade is fixed, a difference in height occurs between the lower blade and the tip of the guide pipe 54. Therefore, when cutting the electric wire L, the electric wire L is kept in contact with the lower blade. Since the wire L is pushed downward only by the upper blade, the electric wire L may be deformed downward. That is, the electric wire L may be bent or may not be cut vertically. If the height of the upper surface of the lower blade and the height of the tip of the guide pipe 54 are made to coincide with each other, the wire L can be brought into contact with the lower blade by feeding the wire L. When rotating in the direction, the tip of the guide pipe 54 collides with the vicinity of the lower blade, and cannot rotate to a predetermined position. Although not described in detail, a similar problem occurs when the electric wire L is inserted into the anvil.
[0006]
Therefore, a mechanism has been proposed in which the tip direction of the guide pipe is changed obliquely downward from the horizontal direction as necessary. That is, when the guide pipe is rotated in the horizontal direction, the tip of the guide pipe 54 is held so as to face the horizontal direction, and when the electric wire L is sent to the cutting mechanism or the anvil, the guide pipe 54 is tilted obliquely downward. It is to be inclined. The mechanism for vertically moving the tip of the guide pipe 54 in the vertical direction includes, for example, a support member such as a bearing for rotatably supporting the guide pipe 54 and a spring or the like for holding the guide pipe 54 in a horizontal state. And a rotation driving means for rotating the guide pipe 54 downward. According to this, when the guide pipe 54 is pressed downward by the rotation driving means, the guide pipe 54 rotates against the elastic force of the elastic means, and the tip of the guide pipe 54 is turned obliquely downward. . When the pressing by the rotation driving means is released, the guide pipe 54 returns to the original state by the elastic force of the elastic means, and the end of the guide pipe 54 is oriented in the horizontal direction.

[Problems to be solved by the invention]
However, the conventional electric wire feeder has a structure in which the guide pipe is rotated in the vertical direction and includes a support member, an elastic means, a rotational drive means, and the like. It was a factor that became. In addition, the cost is increased due to the necessity of many members, and the burden on maintenance is increased.
[0009]
Further, since the guide pipe is connected to the support member via a fastening member such as a screw, the guide pipe cannot be removed from the support member unless the fastening state is loosened. That is, since it is difficult to attach and detach the guide pipe, when changing the type of the guide pipe according to, for example, the diameter of the electric wire L, the burden on the operator in the replacement work is increased.
[0010]
In view of the above situation, it is an object of the present invention to provide a wire feeder capable of smoothly rotating a guide pipe in a vertical direction with a simple configuration and easily attaching and detaching the guide pipe. It is.
[0011]
[Means for Solving the Problems]
A wire feeder according to the first aspect of the present invention provides a pair of rotatable rotators and a pair of rotators which are rotated in opposite directions to each other to feed a wire inserted between the pair of rotators. Driving means, a cylindrical guide pipe for passing the wire fed from between the pair of rotating bodies and restricting a feeding direction of the wire, a mounting member externally fitted to the guide pipe, and magnet attraction A holding member that holds the mounting member by using force; and a direction changing unit that changes a tip direction of the guide pipe from a substantially horizontal direction to an oblique direction against the attraction force of the magnet. . Here, an electric wire can be illustrated as a wire.
[0012]
According to the wire feeder of the first aspect of the present invention, when the pair of rotating bodies rotate in opposite directions by the sending driving means, the wire inserted between the rotating bodies is pressed against and sandwiched by the peripheral surface of the rotating body. Sent out in state. Since the guide pipe is disposed on the wire feed side of the rotating body, the fed wire is inserted through the guide pipe and is fed out from the tip of the guide pipe. That is, the direction in which the wire is sent out is regulated by the guide pipe, and the tip of the wire is directed to an arbitrary position.
[0013]
By the way, the mounting member fitted to the guide pipe is held by the holding member. Here, since the holding member and the mounting member are connected by the attraction force of the magnet, it is possible to attach and detach it very easily. In particular, when the guide pipe is pressed in the up-down direction or the left-right direction by the direction changing means, the tip of the guide pipe is turned obliquely (eg, downward) from a state in which it is directed substantially horizontally against the attraction force of the magnet. Change to state. This makes it possible to direct the tip of the guide pipe to, for example, the lower blade of the cutting mechanism. That is, it is possible to insert the wire in a straight line into the lower blade. On the other hand, when the operation of the direction changing means is stopped, the pressing force in the oblique direction disappears, so that the guide pipe and the mounting member are returned to the original state by the attractive force of the magnet, and the guide pipe is supported in the horizontal state. It becomes.
[0014]
In the wire feeder according to a second aspect of the present invention, in the wire feeder according to the first aspect, the direction changing means supports a predetermined portion contacting the holding member when changing the tip direction of the guide pipe. The mounting member is rotated.
[0015]
Therefore, according to the wire feeder of the second aspect of the present invention, in addition to the operation of the first aspect of the present invention, the fulcrum at the time of rotating the mounting member is a predetermined portion that comes into contact with the holding member. Regardless of the state, the state comes into contact with the holding member. That is, the attachment member can be rotated without detaching the fulcrum of the attachment member from the holding member. In other words, it is possible to rotate the magnet while maintaining the coupling by the attractive force of the magnet.
[0016]

[0018]
Hereinafter, the configuration and operation of each unit will be briefly described. In addition, since the first crimping machine main body 2 and the second crimping machine main body 3 have the same basic configuration, a detailed description of the second crimping machine main body 3 is omitted. The first crimping machine main body 2 includes a support member 8, a guide member 9 that moves up and down by the operation of a power mechanism (not shown), and a base 10 located below the support member 8.

The crushing member 12 moves up and down integrally with the guide member 9.
[0020]
On the upper surface of the base 10, a concave anvil 10a is formed. Therefore, when the electric motor is driven in a state where the crimp terminal is supplied to the anvil 10 a of the base 10, the crushing member 12 moves downward together with the guide member 9 and is formed on the tip of the crushing member 12 and the base 10. The crimp terminal is crushed by meshing with the anvil 10a.
[0021]
Further, the first crimping machine main body 2 is provided with a terminal conveying means (not shown) for sequentially supplying crimping terminals to the anvil 10 a of the base 10. The terminal transport means moves the crimp terminals connected in series along the guide member, and is linked to the operation of the crushing member 12.
[0022]

[0023]
Each component of the wire feeder 1 will be described in detail. Inside the housing 13, a pair of rotating bodies 15, 16 are rotated in opposite directions to each other, and the rotating bodies 15, 16 are passed through the wire intake guide 14 to the rotating bodies 15, 16. A delivery driving means 17 (see FIG. 4) for delivering the inserted electric wire L to the guide pipe 18 is provided. That is, the rotation direction and the number of rotations of the rotating bodies 15 and 16 are controlled by the sending driving means 17, and the length of the electric wire L can be measured and sent.
[0024]
As shown in FIG. 4, the pair of rotating bodies 15 and 16 are arranged at an interval capable of holding the electric wire L, and a peripheral surface thereof is subjected to surface processing for preventing the electric wire L from slipping. Although not shown, the interval between the pair of rotating bodies 15 and 16 can be adjusted according to the diameter of the electric wire L to be processed.
[0025]
The sending-out direction switching means 19 is composed of a mounting member 22 fitted to the base side of the guide pipe 18, a holding member 23 for holding the mounting member 22, and a rotating means 24 for rotating the holding member 23. I have. As shown in FIG. 5, the upper part of the mounting member 22 is an arc-shaped member, and is formed of a magnetic material. In addition, an insertion hole (not shown) through which the guide pipe 18 penetrates is formed in the attachment member 22, and a notch-shaped groove 25 communicating from the upper surface of the attachment member 22 to the insertion hole is formed. Further, the bottom surface of the mounting member 22 is an inclined surface 26 which is inclined downward toward the holding member 23.
[0026]
The holding member 23 is composed of a fan-shaped rotating plate 28 supported by a rotating shaft 27 and a housing 29 fixed to the upper surface of the rotating plate 28 and housing the mounting member 22. The rotating shaft 27 is disposed between the pair of rotating bodies 15 and 16, that is, below a portion that sandwiches the electric wire L. That is, the rotating shaft 27 supports the rotating plate 28 so as to be rotatable in the horizontal direction around a reference point O (see FIG. 6) located between the pair of rotating bodies 15 and 16. Further, a tooth portion 30 is formed on a peripheral surface (that is, a distal end surface) of the rotating plate 28. The housing part 29 is a box-shaped member opened to the tooth part 30 side, and the magnet 31 is fixed to the back surface. That is, when the mounting member 22 formed of a magnetic material is housed in the housing portion 29, the mounting member 22 is attracted by the magnetic force of the magnet 31 and connected to each other. The magnet 31 is provided with a through hole 31a for penetrating the root side of the guide pipe 18. Further, a convex portion 32 is provided vertically downward on the inner peripheral upper surface of the housing portion 29, and when the mounting member 22 is housed in the housing portion 29, the convex portion 32 is in the groove 25 of the mounting member 22. And the holding member 23 and the mounting member 22 are in a fitted state.
[0027]
The rotating means 24 includes a small motor 33 and a pinion 34 supported on a rotating shaft of the motor 33, and is provided in a state where the pinion 34 is meshed with the teeth 30 of the holding member 23. That is, when the pinion 34 is rotated by the operation of the motor 33, the rotation is transmitted to the rotating plate 28, and the rotating plate 28 rotates around the rotating shaft 27 in the horizontal direction. The motor 33 of this embodiment is rotatable in both forward and reverse directions, and rotates the rotary plate 28 between a position where the tip of the guide pipe 18 faces the cutting mechanism 5 side and a position where it faces the first crimping machine main body 2 side. Move.
[0028]
When the electric wire L is fed by the rotating bodies 15 and 16 with the end of the guide pipe 18 facing the cutting mechanism 5, the end of the electric wire L is inserted into the cutting mechanism 5 (arrow A in FIG. 2). When the electric wire L is sent by the rotating bodies 15 and 16 with the end of the guide pipe 18 facing the first crimping machine main body 2 side, the end of the electric wire L is fixed to a predetermined position of the crimp terminal placed on the anvil 10a. It is inserted into the site (arrow C in FIG. 2).
[0029]
As shown in FIG. 4, the direction changing means 20 includes a pressing device 35, and enables the guide pipe 18 to be inclined obliquely downward with the tip of the guide pipe 18 facing the cutting mechanism 5. ing. The pressing device 35 includes a pressing piece 36 that contacts the upper surface on the distal end side of the guide pipe 18 and is displaceable downward, and a solenoid 37 that urges the pressing piece 36 downward. That is, as shown in FIGS. 7A and 7B, when the solenoid 37 is driven to displace the pressing piece 36 downward (that is, when the distal end of the guide pipe 18 is pressed downward against the attraction force of the magnet 31). ), The mounting member 22 and the guide pipe 18 are inclined about the lower end of the mounting member 22 so that the tip of the guide pipe 18 faces the lower blade 41 of the cutting mechanism 5 (the state shown by the two-dot chain line). Here, the lower blade 41 of the cutting mechanism 5 is attached in a fixed state, but by inclining the guide pipe 18 in this manner, the electric wire L can be inserted into the lower blade 41 in a straight line. Become. In particular, since the bottom surface of the mounting member 22 is the inclined surface 26, when the mounting member 22 and the guide pipe 18 are inclined, the lowermost point of the inclined surface 26 corresponding to the corner on the base side is pivoted. Can be done. That is, the mounting member 22 can be inclined while the corners of the mounting member 22 are connected to the magnet 31. That is, the fulcrum of the mounting member 22 can be rotated without being separated from the magnet 31. When the operation of the solenoid 37 is stopped and the pressing by the pressing piece 36 is released, the mounting member 22 is returned to the original state by the attraction force of the magnet 31, and the guide pipe 18 is supported in a horizontal state. The pressing device 35 of this example is disposed between the wire feeding device 1 and the second crimping machine main body 3 (that is, on the right side of the wire feeding device 1). However, in FIGS. 2 shows a state where the device 1 is arranged on the left side.
[0030]
On the other hand, the cutting mechanism 5 is for cutting the electric wire L and removing the covering material at the end of the electric wire L. The cutting mechanism 5 includes a pair of blades (upper blade 40 and lower blade 41) arranged vertically and A moving means (not shown) for moving the blade 40 up and down with respect to the lower blade 41 is provided. That is, in a state where the electric wire L is inserted between the upper blade 40 and the lower blade 41, the electric wire L is cut by operating the moving means so that the upper blade 40 and the lower blade 41 overlap. Further, in a state where the wire L is inserted between the upper blade 40 and the lower blade 41 so that the end of the wire L projects a predetermined length, the distance between the upper blade 40 and the lower blade 41 is equal to the core wire of the wire L. The moving means is operated so as to have a distance corresponding to the size of the wire L. Subsequently, the wire L is pulled by the wire feeder 1 or the chuck mechanism 6 to remove the covering material at the end of the wire L.
[0031]
As shown in FIG. 3, the chuck mechanism 6 is disposed on the rear side of the cutting mechanism 5 and includes a grip 42, a moving unit 43, and a feeding unit 44. The grip 42 is attached to the distal end of the feeding means 44 and holds the electric wire L in a state of being sandwiched therebetween. The moving means 43 is for rotating the grip 42 and the feeding means 44 within a predetermined range so that the grip 42 draws an arc, and the rear end of the wire L is held while the grip L holds the wire L. The side can be moved from the cutting mechanism 5 side to the second crimping machine main body 3 side (arrow D in FIG. 3). The feeding means 44 is for moving the grip 42 in the front-rear direction, and feeds the rear end side of the wire L to a predetermined portion of the crimp terminal placed on the anvil of the second crimping machine main body 3 ( After the crush of the crimp terminal together with the arrow E) in FIG. 3, the wire L to which the crimp terminal has been crimped is discharged from the anvil.
[0032]
Next, an operation of sending out the electric wire L by the wire feeder 1 will be described with reference to FIGS. When the rotating body 15 is rotated in the counterclockwise direction and the rotating body 16 is rotated in the clockwise direction by the sending driving means 17, the electric wire L inserted between the pair of rotating bodies 15 and 16 through the electric wire intake guide 14 rotates. It is sent out while being held between the peripheral surfaces of the bodies 15 and 16. Since the guide pipe 18 is provided on the rotating body 15, 16 on the sending side of the electric wire L, the sent electric wire L passes through the guide pipe 18 and is fed out from the tip of the guide pipe 18. That is, the direction in which the electric wire L is sent out is regulated by the guide pipe 18, and the end of the electric wire L faces the cutting mechanism 5. In particular, as described above, the direction changing means 20 functions when the tip of the guide pipe 18 faces the cutting mechanism 5. That is, the guide pipe 18 is inclined obliquely downward by the pressing device 35, and the electric wire L is sent out in that state.
[0033]
On the other hand, when switching the direction in which the electric wire L is sent out to the first crimping machine main body 2 side, after the pressing by the pressing device 35 is released, the guide pipe 18 is rotated in the horizontal direction to change the direction of the guide pipe 18. Let it. At this time, the guide pipe 18 is rotated without rotating the rotating bodies 15, 16 and the electric wire taking-in guide 14 in the horizontal direction. That is, the guide pipe 18 is rotated by rotating the holding member 23 by the rotation means 24 in a state in which the attachment member 22 externally fitted to the guide pipe 18 is connected to the holding member 23. In this case, the guide pipe 18 rotates around a reference point O located between the pair of rotating bodies 15 and 16. For this reason, even if the guide pipe 18 rotates while the electric wire L is held between the pair of rotating bodies 15 and 16, the portion where the electric wire L is held by the rotating bodies 15 and 16 and the base side of the guide pipe 18 can Is constant, and no tensile force acts on the electric wire L. That is, even if the guide pipe 18 is rotated while the electric wire L is inserted, the rotation is not suppressed by the presence of the electric wire L. Also, regardless of the direction in which the guide pipe 18 is rotated, the wire L is supported in a straight line from the portion where the wire L is sandwiched to the tip of the guide pipe 18, so that the pair of rotating bodies 15, 16 Can be smoothly inserted into the guide pipe 18.
[0034]
As described above, in the wire feeder 1 described above, the direction of the distal end of the guide pipe 18 can be switched from the horizontal direction to the downward direction only by pressing the upper surface on the distal end side of the guide pipe 18. The guide pipe 18 can be returned to the original state only by canceling. Therefore, the distal end of the guide pipe 18 can be rotated in the vertical direction with a very simple configuration, and the cost and the size of the device can be reduced. In particular, since the rotation is performed with the lowest point of the inclined surface 26 of the mounting member 22 as a fulcrum, the rotation can be smoothly performed while the coupling by the attraction force of the magnet 31 is maintained. In addition, since the original state is restored by the attraction force of the magnet 31, the configuration of the pressing device 35 can be simplified, and energy consumption can be suppressed.
[0035]
Further, in the wire feeder 1 described above, since the attachment member 22 and the holding member 23 are connected by the attraction force of the magnet 31, even if the type of the guide pipe 18 is changed according to the diameter of the electric wire L, it is extremely difficult. It can be easily handled. In addition, since the attachment member 22 and the holding member 23 are fitted to each other when connected, the detachment of the attachment member 22 during rotation can be suppressed, and the rotation can be performed in a stable state. Since the groove 25 penetrates in the front-back direction, the attachment member 22 can be easily removed by pulling the guide pipe 18 toward the distal end.
[0036]
As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and various improvements can be made without departing from the gist of the present invention as described below. And design changes are possible.
[0037]
That is, in the wire feeder 1 described above, as a means for connecting the attachment member 22 and the holding member 23, the attachment member 22 is formed of a magnetic material and the holding member 23 is provided with the magnet 31. The holding member 23 may be formed of a magnetic material, and the holding member 22 may be formed of a magnet. Further, both the mounting member 22 and the holding member 23 may be configured by magnets.
[0038]
In the wire feeder 1 described above, the tip of the guide pipe 18 is changed in the downward direction. However, the guide pipe 18 is changed in the required direction, for example, in the upward, right, and left directions. You may. For example, in the case of changing the mounting member 22 upward, if the upper surface of the mounting member 22 is tilted so that the magnet 31 side becomes higher, the mounting member 22 can be rotated with the vertex of the inclined surface as a fulcrum. That is, also in this case, it is possible to smoothly rotate while maintaining the coupling by the attraction force of the magnet 31.
[0039]
In the wire feeder 1 described above, the bottom surface of the mounting member 22 is shown as being inclined. However, the inner peripheral lower surface of the housing portion 29 facing the bottom surface of the mounting member 22 may be relatively inclined. . Even when formed in this manner, the mounting member 22 can be rotated around the corner on the magnet 31 side as a fulcrum, and can be smoothly rotated while maintaining the coupling by the attractive force of the magnet 31. .
[0040]
Further, in the above-described wire rod feeding device 1, the electric wire L is shown as the wire rod, but a flexible pipe or the like may be held instead of the electric wire. In this case, the thickness of the wire is not particularly limited.
[0041]
【The invention's effect】
As described above, the wire feeder according to the first aspect of the present invention can switch the direction of the distal end of the guide pipe from the horizontal direction to the downward direction only by pressing the upper surface on the distal end side of the guide pipe. Further, the guide pipe can be returned to the original state only by releasing the pressing on the guide pipe. Therefore, the tip of the guide pipe can be rotated in the vertical direction with a very simple configuration, and it is possible to reduce the cost and reduce the size of the device. Moreover, since the guide pipe can be easily removed from the holding member, it is possible to easily cope with, for example, changing the type of guide pipe according to the diameter of the wire rod, thereby improving production efficiency in high-mix low-volume production. Can be done.
[0042]
According to the wire feeder of the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, the guide pipe and the mounting member can be smoothly rotated, and the coupling by the attraction of the magnet is maintained. Can be rotated. Therefore, a stable rotation operation can be realized despite the simple configuration.
