Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a device for bending the external conductor of an annular fluorescent lamp.

(Prior art) Generally, in an annular fluorescent lamp, after the bulb is formed into an annular shape, it is necessary to light the electrode filament for decomposition of the cathode material in the electrode part. The two pairs of lead-out external conductive wires are bent in opposite directions, and while the bulb is being transported, these external conductive wires are brought into contact with the power supply rail to light up.

(Problem to be solved by the invention) By the way, in order to bend the above-mentioned external conductor, conventionally the external conductor is hooked with an external conductor bending member that rotates close to the end of the bulb, and the external conductor is held in a predetermined position. It was designed to bend in the direction of However, in the conventional one, this external conductor bending member is the sixth
As shown by the dashed line The external conductor bending member bends the external conductor while sliding from the distal end to the proximal end of the external conductor. This has caused problems such as the external conductor being deformed during bending and the bending position of the external conductor being inaccurately regulated.

SUMMARY OF THE INVENTION The object of the present invention is to provide an external conductor bending device for an annular fluorescent lamp, which has a relatively simple structure and can accurately bend an external conductor.

[Structure of the invention] (Means for solving the problem) The present invention includes a holding mechanism that holds the bulb end of an annular fluorescent lamp, and a holding mechanism that is provided on the side of this holding mechanism and is rotated by a drive device. a rotating member; a sliding member attached to the rotating member so as to be slidable in a radial direction with respect to its rotational center; and a sliding member that is biased in one direction by a coil spring; and one end of the sliding member. A cam roller attached to the cam roller is pressed into contact with the cam roller under the urging force of the coil spring, and the sliding member, which is rotated integrally with the rotation of the rotary member, is moved in the radial direction. and a cam mechanism, which is provided at the other end of the sliding member and rotates integrally with the rotation of the rotating member, and is moved in the radial direction by the sliding action of the cam roller and the cam mechanism. The ring-shaped fluorescent lamp held by the holding mechanism is moved close to the bulb end in the circumferential direction of the bulb end by a predetermined angle, thereby hooking and bending the external conductor led out from the bulb end. It is characterized by comprising an external conducting wire bending member that deforms the external conducting wire.

(Function) According to the present invention, when the rotating member is rotated by the drive device, the sliding member also rotates integrally, and the cam roller attached to one end of the sliding member is pressed by the coil spring. The external conductor bending member moves along the cam surface of the cam mechanism under the force, so that the external conductor bending member comes close to the bulb end of the annular fluorescent lamp held by the holding mechanism and is moved around the end of the bulb end. direction by a predetermined angle. Therefore, the external conductor bending member hooks the external conductor led out from the end of the bulb and moves at a predetermined angle in the circumferential direction of the bulb, thereby bending and deforming the external conductor. The member abuts against the external conductor at a certain position at the proximal end, and continues to press this position to bend and deform it.

(Example) The present invention will be described below with reference to an example shown in the drawings.

In the figure, reference numeral 1 denotes a holding mechanism that grips the end of the bulb A of the annular fluorescent lamp. A base 2 is provided on the side of this holding mechanism 1. A rotating member 3 is provided on the base 2. The rotating member 3 is located on the sides of the opposing ends of the valve A held by the holding mechanism 1. Further, a rotating shaft 4 is attached to this rotating member 3, and a pinion 5 is attached to the lower end of this rotating shaft 4.
A rack member 6 is provided on the base 2 so as to slidably pass through the base, and the rack member 6 meshes with the pinion 5. This rack member 6 is driven by an air cylinder 7 provided on the lower surface of the base 2, and as the rack member 6 moves, the rotating member 3 is configured to rotate back and forth. .

The rotating member 3 is provided with a sliding member 8. This sliding member 8 is provided with a pair of sliding rods 9, 9, which are slidably penetrated in the radial direction of the center of rotation of the rotating member 3. and,
Compression coil springs 10, 10 are interposed between the sliding member 8 and the rotating member 3, and these compression coil springs 10, 10 cause the sliding member 8 to move forward in the forward direction. Forced.

A cam plate 11 is provided between the rotating member 3 and the base 2. This cam plate 11 is fixed to the base 2 side, and its rear end surface is formed as a cam surface. A roller 12 is attached to the rear end of the sliding member 8, and the roller 12 is pressed against the cam surface of the cam plate 11 by the biasing force of the compression coil springs 10, 10. Note that 16 is an arc-shaped guide member that guides the rotating member 3.

An external conducting wire bending member 13 is provided protruding from the tip of the sliding member 8 . This external conductor bending member 1
At the tip of 3, there is a plate-shaped contact part 1 along the vertical direction.
4 is formed, and V-shaped guide notches 15, 15 are formed on the side edges of this contact portion 14 to guide the external conductors B of the bulb A when they come into contact. As the rotating member 3 rotates, the roller 12 of the sliding member 8 rolls along the cam surface of the cam plate 11, and as a result, the sliding member 8 moves back and forth with respect to the rotating member 3. The external conductor bending member 13 is shown in FIGS. 2 and 6 by the two-dot chain line Y.
It is configured to move in a trajectory along the outer periphery of the end of the valve A as shown in FIG.

In one embodiment of the present invention configured as described above, when the rack member 6 is moved by the air cylinder 7, the pinion 5 meshing with the rack member 6 is moved.
rotates, and the rotating member 3 is rotated. As this rotating member 3 rotates, the sliding member 8
The roller 12 rolls along the cam surface of the cam plate 11, and the sliding member 8 is moved forward and backward. Therefore, the external conductor bending member 13 is close to the end of the valve A, and the abutting portion 14 is located close to the end of the valve A, as shown in FIGS. 3 to 5.
contacts the external conductor B, hooks it, and bends it in a predetermined direction. In this case, the external conductor bending member 1
3 moves along a locus that follows the outer circumference of the end of the bulb A, so the abutment part 14 of the external conductor bending member 13 abuts the base end of the external conductor B... and moves around this base end. Push it in the direction, so bend it. Therefore, the external conductive wires B can be accurately bent without being deformed.

[Advantages of the Invention] As described above, according to the present invention, the external conductor bending member abuts against the base end of the external conductor and presses this position to bend the external conductor, so there is no deformation of the external conductor,
It can be bent accurately.

Moreover, since a cam mechanism and a rotary drive device are used to move the external conductor bending member toward and away from the valve and in the circumferential direction of the valve, the overall structure of the device is simple.
