Description

Device for mounting the sleeve on the filament lead for bulbs

The present invention relates to a device for mounting a sleeve to a filament lead for bulbs, and more particularly to a sleeve device for automatically attaching molybdenum sleeve to the lead of the filament in order to attach the filament to the lead of the pole.

In general, a lighting lamp using tungsten filament as a light emitting body such as an incandescent lamp or a halogen lamp is connected to the filament by attaching a molybdenum sleeve to both ends of the filament, that is, a lead, in order to attach the filament to the lead line (power supply line) of the bulb.

As such, in order to mount the sleeve to the filament's lead, a conventional example of such a conventional sleeve mounting apparatus is shown in Fig. 1 by inserting a tubular sleeve into the filament's lead and pressing it using a compactor. It was.

As shown in FIG. 1, a conventional sleeve mounting apparatus includes a feeder 5 for moving the filament 1 in a horizontal direction, and a lead of the filament 1 moving in the horizontal direction by the feeder 5. In order to insert the sleeve 3 into the (2), the slide plate 4 for dropping the plurality of sleeves 3 at an oblique angle and the sleeve 3 inserted in the lid 2 of the filament 1 are crimped. It consists of a presser (not shown in the figure) or the like installed on one end of the feeder 5 to fix it.

The conventional sleeve mounting device configured as described above coincides with the direction in which the filament 1 lead 2 is transversely fed by the feeder 5 to insert the sleeve 3 into the filament 1 lead 2. The slide plate 4 is installed to continually lower the sleeve 3 at an angle to be achieved. At this time, the slide plate 4 is formed with a plurality of grooves, and the sleeve 3 is lowered by the grooves.

Thus, when the sleeve 3 randomly descending from the slide plate 4 is inserted into the lid 2 of the filament 1, the filament 1 continues to move in the horizontal direction and is pressed by the presser to the sleeve 3. ) Is crimped and fixed to the lid 2.

However, because the sleeve is inserted into the lid as it slides down from the slide plate, not all sleeves are inserted into the lid, but a large number of sleeves fall to the bottom, and also the filaments are ejected out without the sleeve inserted and finally There is a problem that the filament that is not mounted by selecting the filament and the filament is not mounted, the sleeve is to be reworked.

In addition, since the molybdenum sleeve inserted into the lead has a tubular shape, the production cost of the molybdenum sleeve increases, resulting in a decrease in productivity.

The present invention is to solve the conventional problems as described above, the productivity of the molybdenum sleeve mounted on the lead of the tungsten filament used as a light source body of the bulb automatically by using a ribbon-shaped molybdenum ribbon rather than tube form It is an object of the present invention to provide a device for mounting a sleeve on a filament lead for a bulb that improves.

The device for mounting the sleeve on the filament lead for bulb according to the present invention configured as described above acts as follows.

A large amount of filament in which the molybdenum sleeve is not attached to the lid is introduced into the supply container 10. The supply cylinder 10 vibrates finely and is fed in a row through the feeder 11 while the filaments are aligned by the vibration. At this time, the turntable 70 is also rotated counterclockwise by the motor 72 and the reducer 75 at intervals of 45 °.

The loader 15 transfers the filaments supplied through the feeder 11 to the clamp 80 one by one, which is carried out by the loader head 18 by the loader cylinder 16 so as to feed back the feeder 15. Catch the filament. At this time, the force for holding the filament utilizes the force generated by sucking air through the loader head 18. When the filament is held by the loader head, the loader cylinder 16 is operated to move the loader rod 17 to move the loader head 18 to the position of the clamp 80. At this time, the clamp 80 which has been moved to the position of the loader 15 is opened by the pressing plate 73, and the filament transferred by the loader 15 is mounted.

The clamp 80 supplied with the filament by the loader 15 moves again by 45 ° (which is moved by the rotation of the turntable 70) and moves to the position of the confirmation sensor 19 to confirm the presence of the filament. .

When the filament is present in the clamp 80 by the confirmation sensor 19, the filament is moved by 45 ° again to move to the first sleeve mounter 20.

Subsequently, the bent portion 29 is in the original position as shown in FIG. 6C, and when the bent molybdenum ribbon 35 is advanced as shown in FIG. 6D, the upper and lower ends of the clamp 80 of FIG. The lead 91 of the filament held in the jaws 38 and 84 is supplied at the bent portion of the molybdenum ribbon 35. Therefore, the process (a to d) until the molybdenum ribbon 35 is bent and advanced is made before the lead 91 of the filament mounted on the clamp 80 arrives at the first sleeve mounter 20.

As described above, when the filament lead 91 is inserted into the bent portion of the molybdenum ribbon 35 (d in FIG. 6), the molybdenum is formed by the pair of crimp portions 26 and 27 as shown in FIG. The bent portion of the ribbon 35 is pressed, and then the cutter 28 is raised to cut the molybdenum ribbon 35 to complete the sleeve 99 formation.

When the sleeve 99 is formed in this way, the pressing portions 26 and 27 are opened, and the cutter 28 is lowered, so that one end of the molybdenum ribbon 35 is retracted to the lower end of the bent portion 29 to mount the sleeve. Will complete.

When the sleeve is mounted on one side of the filament lead by the first sleeve mounter 20 as described above, the turntable 70 is rotated by 45 ° so that the filament with the sleeve mounted on the lead is positioned in the first presser 40. Done.

The sleeve mounted on the filament moved to the first presser 40 has a pair of pressing tips attached to one end of the pair of levers 42 which are operated by the action of the presser cylinder 43 and the presser rod 44. It is pressed and fixed by 46. On the other hand, the pair of levers 42 is the angle of the opening is limited by the stopper 45 provided to limit the operating range.

As described above, in order to mount the sleeve to the other lead of the filament in which the sleeve is mounted and fixed to one lead by the first presser 40, the filament must be rotated by using the rotator 50. In this rotation process, when the clamp 80 on which the filament is mounted is moved, the rotator head 54 is lowered by the action of the rotator cylinder 51 and the rotator rod 53, and the filament is used by the rotor 55. Catch. At this time, the force for holding the filament uses the force generated by sucking air. When the filament is caught by the rotor 55, the rotor 54 is rotated 180 degrees, the rotator rod 53 is lowered again, and the filament is placed on the clamp 80.

When the clamp 80 with the changed direction of the filament lead moves 45 ° to arrive at the second sleeve mounter 39, the sleeve is mounted on the other lead through the same process as the first sleeve mounter 20 described above. The sleeve mounted to the lid by the second press 49 is press-fixed and separated from the clamp 80 by the ejector and discharged.
