[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead wire supply device, and more particularly, to a lead wire supply device capable of bending a lead wire while carrying the lead wire.

[0002]

2. Description of the Related Art Conventionally, it is necessary to supply a lead wire in a process of sealing a lead wire to a glass tube, for example, in a manufacturing process of an illumination lamp. In this case, it is necessary to supply a linear lead wire. It is bent in advance and transported by multiplying it on a linear feeder (Fig. 8), or transported by parts feeder or magazine (Fig. 9) and bucket (Fig. 10).
For example, a method in which the sheet is held and transported by the above method has been adopted. However, when transporting a large number of linear feeders, it is difficult to separate the individual lead wires because the lead wire diameter is as small as about 0.3 mm to 0.5 mm. In this case, the lead wires are entangled with each other during transportation, so that separation is also difficult in this case. further,
The above-mentioned problem does not occur when transporting the apparatus by attaching it to a magazine, a bucket, or the like. However, the work of holding the respective lead wires in the magazine or the like is required, and the efficiency is poor.

In addition, since the lead wire is previously formed into a U-shape or U-shape in a separate process before being fed and supplied, the number of processes is increased, workability is poor, and equipment such as a parts feeder and a magazine is required. Therefore, it was difficult to supply a stable lead wire.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the conventional lead wire supply and to provide an apparatus which can supply work leads with good workability at high speed and with stability. .

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a long axis extending along a longitudinal axis, and is disposed coaxially with the long axis to slidably support the long axis. A first hollow shaft, a second hollow shaft coaxially disposed radially outward of the first hollow shaft and rotatable around the first hollow shaft, and one end of the second hollow shaft The second
A main body having an arm member extending radially outward from the hollow shaft, and provided at the one end at an end provided on the arm member so as to be rotatable around an axis extending in a direction perpendicular to the long axis. A bending shaft to which a roller is attached, a holder fixed to the arm member and having a mandrel arranged at one end adjacent to the roller, and a pivotally supported one end supported by the holder and cooperating with the mandrel. A first lever provided with a claw for holding the lead wire by operating, and a link mechanism for swinging the first lever in conjunction with the sliding movement of the long axis; Is rotated about the right-angle axis in conjunction with the rotation of the first hollow shaft, so that the roller rolls around the mandrel, whereby the first hollow shaft is rotated simultaneously with the rotation of the first hollow shaft. Held by the mandrel and the claw And it is configured to bend the lead wire.

[0006]

In the above construction, the lead wire sent straight is held by the claws and the mandrel. While holding the lead wire, the first lever on which the claw is mounted and the holder on which the mandrel is mounted are rotated by a predetermined angle around the long axis of the main body. At the same time, when the bending shaft is rotated around an axis perpendicular to the long axis, the roller mounted on the bending shaft rolls around the mandrel, and the straight line is held by the claw and the mandrel. Bend the lead wire. Therefore, the lead wire is bent simultaneously while rotating the lead wire. The release of the lead wire is performed by swinging the first lever by the link mechanism to bring the pawl into engagement or non-engagement with the mandrel.

The arm member 5 constitutes the main body 11 of the lead wire supply device 1. The main body 11 is supported by a tubular member 6 mounted coaxially outside the second hollow shaft 4, while the tubular member 6 is fixed to a frame (not shown) in a known manner, thereby providing a lead wire supply. The device 1 is held on a frame.

A boss 7 is attached to the tip of the arm member 5. The boss 7 is provided with a through hole 72 along an axis 71 extending in a direction perpendicular to the longitudinal axis 21. The bending shaft 8 passes through the through hole 72 and is supported by a bearing. A pinion gear 81 meshing with the bevel gear 32 of the first hollow shaft is attached to one end of the bending shaft 8,
The other end is formed in a substantially lock shape, and a roller 83
Are arranged. The bending shaft 8 rotates around the axis 71 together with the pinion gear 81.

As shown in FIG. 2, one end of a holder 9 is fixed to the outer surface of the boss 7. The other end of the holder 9 is bent at an angle of 90 degrees, and a mandrel 91 is attached to a tip of the holder 9 with a nut. The mandrel 91 is disposed at a position adjacent to the roller 83 with a slight gap therebetween (FIG. 5).

As shown in FIGS. 2 and 5, a lever 10 is disposed adjacent to and below the holder 9. The lever 10 is attached to the holder 9 by bolts and nuts 101 and 102.
And nuts 101 and 102
Can be rotated on a plane perpendicular to the longitudinal axis 21. A cam follower 103 is attached to one end of the lever 10, and a claw 104 is provided at a position adjacent to the mandrel 91 at the other end. The claw 104 has a V-shaped tip and engages or separates from the mandrel 91 to grip or release a linearly supplied lead wire as described later. A press spring 105 is mounted between the lever 10 and the holder 9 as shown in FIG.

As shown in FIGS. 1 and 3, a bracket 150 is mounted on the upper surface of the boss 7. A shaft 151 extending through the bracket 150 is supported by a bearing, and one end of the shaft 151 has a link member 1 attached thereto.
52, and a lever 153 is attached to the other end. The lever 153 has an inclined cam 154 formed at the end thereof and is in contact with the cam follower 103 of the lever 10 (FIG. 2). A roller 155 is attached to one end of the link member 152 and is in constant contact with the disk 20 disposed at one end of the long shaft 2, while the other end of the link member 152 has one end at the boss 7.
Is engaged with the coil spring 156 attached to the helical spring. The coil spring 156 is provided on the side of the disc 20 so that the roller 155 of the link member 152 and the disc 20 are kept engaged with each other.
Energize 55. The link mechanism 15 is composed of the shaft 151, the link member 152, the lever 153, the inclined cam 154, the roller 155, and the coil spring 156. Further, the bending portion 8, the holder 9, the bevel gear 81 and the lever 10 constitute the head portion 12. The entire head portion 12 rotates by a predetermined angle around the long axis 21.

The operation of the above configuration will be described below.

(1) As shown in FIG. 2, the head section 12 of the lead wire supply device is initially positioned at the position I.
In this case, the pawl 104 and the mandrel 91 are separated from each other, and the lead wire 16 is inserted between the pawl 104 and the mandrel 91 from above vertically in FIG. 2 (FIG. 7).
(I)). The lead wire 16 is fed out of the spool by another conventional device, cut to a fixed size, and formed in a straight line.

(2) After inserting the lead wire, the disk 20 is also moved to one end by sliding the long shaft 2 to one end (left side in FIG. 1), and the link member 152 is resilient by the coil spring. Rotates in the direction of arrow K. Therefore, lever 15
3 rotates in the direction of arrow L (FIG. 4), the inclined surface of the cam 154 moves in the direction away from the cam follower 103, and subsequently the lever 10 rotates about the bolt 101 in the direction of arrow M (FIG. 2). As a result, the pawl 104 is engaged with the mandrel 91 to hold the lead wire (FIG. 7B). This state is shown in detail in FIG. 6 by solid lead wires.

(3) Next, the arm member 5 and the head section 12 are moved through the second hollow shaft 4 by the arrow N by moving the lever 41 upwardly in the plane of FIG. 2 to the position II in FIG. That is, the head portion 12 revolves around the long axis 21, but the bending shaft 8 rotates about the axis 71 in conjunction with the revolving motion by the engagement between the bevel gear 32 and the pinion gear 81. . Accordingly, the roller 83 attached to the tip of the bending shaft 8 rolls around the mandrel 91 in the direction of arrow 0 as shown in FIG.
The roller 83 bends the lead wire into a U-shape around the mandrel while in contact with the lead wire (see FIGS. 7B to 7D). In this case, since the lead wire has a spring force, simply bending the lead wire to the predetermined position P causes springback, so that it is necessary to excessively bend the lead wire to the rolled position Q. .

(4) This operation is performed as follows. When the head portion 12 revolves around the long axis 21, the lever gear 34 is rotated in the direction opposite to the direction of the lever 41, so that the bevel gear 32 rotates in a direction opposite to the revolving direction of the head portion 12, so that a pinion is formed. The gear 81 rolls more by an amount corresponding to the amount by which the bevel gear 32 rotates in the opposite direction. As a result, the bending shaft 8 to which the pinion gear 81 is connected also rolls extra around the mandrel 91, and when the end of the lead wire finally comes to the position Q, a stopper (not shown) And so on.

(5) In this way, the lead wire sent in a straight line can be formed while being rotationally transferred from the position I to the position II.

(6) The lead wire after molding performs an operation reverse to the operation described in (2) above, whereby the engagement between the pawl 104 and the mandrel 91 is released (FIG. 7 (e)). It is transferred to the next step by another device.

[0022]

[Effect of the Invention] In the present invention, it is possible to simultaneously form a lead wire sent in a straight form while rotating and transferring the lead wire. Therefore, the formed lead wire is transferred by a conventional linear feeder, magazine or bucket. This eliminates the necessity of attaching and removing the lead wires to and from them. Therefore, the process can be simplified, and high-speed and reliable supply and molding of the lead wire can be provided.
