Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for feeding coiled parts, such as light bulb filaments, in a vibrating parts feeder.

The filament of a light bulb is coiled and generally has a length of about 15 to 60 mm and a diameter of 0.3 to 1.0 mm.Single parts of this kind are fed to the subsequent process using a vibrating parts feeder. may be required. A vibrating parts feeder, also called a parts feeder, has a spiral track formed on its inner peripheral wall and is equipped with a so-called pole that receives torsional vibration force. This pole is subjected to torsional vibration force by a known torsional vibration force generator, and a large amount of filament is put into the middle of the pole, and the pole moves upward in a spiral track. Such filaments are very easy to entangle with each other;
Most of them are already entangled when they are introduced, but
Torsional vibration forces can considerably disentangle these entanglements. However, the filament is often fed from the discharge end of the track in a still tangled state.

The present invention has been made in view of the above points, and provides a feeding device for coiled parts in a vibrating parts feeder that can feed coiled parts such as filaments that are easily tangled in a state of being almost completely separated from each other. The purpose is to According to the present invention, this object is achieved by forming a spiral track on the inner circumferential wall of a vibrating component feeder equipped with a component receiving section receiving torsional vibration force, in which a spiral track is formed on the inner circumferential wall, and a straight line is provided at or near the end of the track. A groove is provided inside the groove, which extends in a straight line, has a length at least twice the axial length of the coil to be sorted, has a width slightly larger than its diameter, and is open only upward. A device for conveying coiled parts in a vibrating parts feeder, characterized in that the coiled parts are separated from each other while being transported along the axial direction of the coiled parts. .

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a parts feeder equipped with a parts feeding device according to this embodiment. There is. Although not shown in the drawings, the ball 10 receives a vibration force that causes it to reciprocate around its center as shown by arrow A, that is, a torsional vibration force, by a known torsional vibration force generator. This vibration force is in the circumferential direction of the track 2 and is inclined at a predetermined angle with respect to the transport surface of the track 2. The filament m, which is a component to be transported, moves up on the track 2 as shown by arrow B under the vibrational force. It should be noted that a large amount of filament m is thrown into the ball 10, but for the sake of clarity, it is shown in a scattered manner and is shown in a different proportion from the actual size.

The parts sorting device 3 according to the present invention is connected and fixed to the terminal end of the track 2 of the ball 10, and furthermore, the discharge end of this parts sorting device 3 is connected to a parts supply trough that extends in an arc shape substantially concentrically with the track 2. 4 is connected and fixed. As clearly shown in FIG. 2, the parts sorting device 3 of this embodiment consists of a guide member 5 and a groove forming block 6.
The upper surface thereof is an inclined surface 5a, as shown in FIG. The groove forming block 6 has a flat plate shape as a whole, but a groove 6a that is cut diagonally and extends linearly is formed on its inner surface. The width and depth of this groove 6a are slightly larger than the diameter of the filament m, as shown in FIG. For example, the width is 0.05~0.1mm
The depth is slightly larger than this.
The component supply trough 4 has a groove 4a having a substantially U-shaped cross section, the width of which is also slightly larger than the component m. Further, it is fixed to the ball 10 via the member 7.

The present embodiment is configured as described above, and its operation will be explained next. In this embodiment, the diameter of the ball 10 is approximately 300 mm, and the length of the groove 6a is approximately
It is said to be 70-90mm.

When a torsional vibration generator (not shown) is driven, the ball 10 causes torsional vibration around its center, and a large amount of filament m introduced into the center bottom moves up the track 2 as shown by arrow B. , transitions from the discharge end of the track 2 to the slope of the guide member 5. As shown in FIG. 2, the width of the slope 5a of the guide member 5 is smaller than the width of the track 2, so of the filaments m transferred in two rows on the track 2, the filaments m in the inner row are transferred to the track 2. The filaments m in the outer row fall from the discharge end of the filament 2 into the inner part of the roll 10, but the filaments m in the outer row fall on the slope 5.
a and falls into the groove 6a. The transfer surface of the track 2 is also slightly inclined outward like the slope 5a of the guide member 5, and its width is slightly larger than twice the diameter of the filament m. It may be slightly larger than the diameter.

Since the amplitude of the torsional vibration force is larger toward the outer part of the track 2, the filament m is transported at a considerably higher speed near the discharge end of the track 2. However, since the groove 6a is configured in a straight line, a torsional vibration force is applied to each point according to the distance from the center of the ball 10, but the force as a whole is supplied from the discharge end of the track 2. It acts like applying a brake to filament m. That is, since the width of the groove 6a is only slightly larger than the diameter of the filament m, the movement of the filament m in the width direction of the groove 6a is restricted, and furthermore, since the magnitude of the torsional vibration force is non-uniform, , the filament m transferred from the track 2 into the groove 6a reduces the transfer speed and moves into the groove 6a.
A is subjected to a complex vibrational force having components in the longitudinal direction and the width direction. Furthermore, it receives the pushing force of the filament m from the track 2. The filaments m, which were intertwined with each other, are separated by these. In this case, the filaments m entangled in the longitudinal direction are separated in the groove 6a and transferred one by one to the groove 4a of the supply trough 4, but the upper part of the filaments m entangled in the radial direction The filament m falls into the ball 10 from the groove 6a.

Since the groove 4a of the supply trough 4 extends almost concentrically with the track 2 of the ball 10, it receives a uniform torsional vibration force as a whole like the track 2, and separates the parts from the parts sorting device 3 one by one. The filament m discharged into the groove 4a is transferred again at a high transfer speed. As a result, the filaments m are discharged from the groove 4a at approximately constant intervals.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the groove forming block 6 was connected to the discharge end of the track 2 of the ball 10;
Alternatively, it may be provided in the middle of the track 2 near the discharge end. In this case, supply trough 4
can be omitted. Also, ball 10
Instead of the feed trough 4 which is subjected to vibration forces, a vibratory feeder having a linearly extending trough may be connected in series to the groove-forming block 6.

Further, the guide member 5 can also be omitted if the mounting position of the groove forming block is appropriately determined with respect to the discharge end of the track 2.

Further, the depth of the groove 6a of the groove forming block 6 may be smaller than the diameter of the filament m as long as the filament m can be stably held in one layer. Also filament m
Since the grooves 6a are particularly easy to become entangled in the longitudinal direction, the depth of the groove 6a may be made sufficiently large if there is no risk of the grooves becoming entangled in the radial direction.

As described above, the coiled component feeding device in the vibrating component feeder of the present invention extends linearly at or near the terminal end of the spiral track formed on the inner circumferential wall of the component receiver, A groove having a length at least twice the length in the axial direction of the coiled parts to be sorted, a width slightly larger than the diameter, and opening only upward is provided, and the coil is inserted into the groove. While the coiled parts are transported along the axial direction, the coiled parts are separated from each other.
Inside, a braking effect is obtained on the transfer of the coiled part fed to the starting end, and this is not caused by uniform torsional vibration, but because the groove is linear, the transfer speed is different in each part, and Since the width of the groove is only slightly larger than the diameter of the coiled part, it restricts the lateral movement of the coiled part, and furthermore,
Due to this movement, the thrusting forces from both side walls and the bottom wall of the groove repeatedly act on the entangled portion of the coiled part, thereby producing the special effect of separating the entanglement. For example, coiled parts that easily get tangled, such as filaments, can be separated and supplied one by one.
