Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a vibrating bowl feeder device, and in particular, an annular magnet is disposed approximately concentrically on the outside of a vibrating bowl, and this annular magnet is used to generate vibrations in a vibrating bowl feeder. The present invention relates to a vibratory bowl feeder device which is rotated synchronously by the device.

[Conventional technology]

Generally, vibrating bowl feeders are widely used when feeding electronic components such as capacitors stored in a hopper to a place of use. Electronic components such as capacitors stored in the vibrating bowl are sent out from the inside to the outside on a spiral trajectory by the vibration action. Near the exit of the track, the capacitor is transformed from a horizontal position to a vertical position and, if necessary, is transported vibrating to a distant location using a linear feeder. This change in attitude is usually carried out by directing the head of the capacitor inward, protruding the lead wire outward from the gap under the vertical guard, and lowering the lead wire vertically downward from the middle.

[Problem that the invention seeks to solve]

However, in the conventional vibrating bowl feeder device described above, there is a problem that if the head of the capacitor is heavy, the capacitor falls into the vibrating bowl, resulting in poor feeding efficiency.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vibrating bowl that prevents electronic components with heavy heads from falling into the vibrating bowl during feeding, and that prevents any resistance force from acting on the lead wires of electronic components in the feeding direction. The purpose of the present invention is to provide a feeder device.

[Means for solving problems]

In order to solve the problems mentioned above, the vibrating bowl feeder device according to the present invention includes a vibrating bowl having a spiral trajectory extending from the inside to the outside on its inner surface, and a vibrating bowl attached to the lower part of the vibrating bowl. A vibration generator that generates transportable vibrations in the circumferential direction of the bowl; and an annular magnet that is arranged on the outside of the vibrating bowl and approximately concentrically with respect to the bowl, and that attracts lead wires of electronic components. It is characterized by the fact that

[For production]

The electronic components, which have been vibrated and transported along the orbit inside the vibrating bowl, are vibrated in perfect synchronization with the vibrating bowl feeder while receiving the attraction action of an annular magnet that moves in the circumferential direction by the vibrating bowl feeder's vibration generator. transported.

〔Example〕

An embodiment of a vibrating bowl feeder according to the present invention will be described below with reference to the drawings.

The vibrating bowl feeder device according to the present invention has a mortar-shaped vibrating bowl 1 and a vibration generating device 2 attached to the lower surface of the vibrating bowl 1 to generate transport vibrations to the vibrating bowl 1. This vibration generator 2 is known per se, and is composed of an electromagnet that generates electromagnetic vibrations, a plurality of diaphragm springs that support the bowl and convert it into transportable vibrations, and a controller. .

On the other hand, the vibrating bowl 1 is formed with a spiral track 4 extending from the bottom toward the outer periphery, and a support rail 5 curved into an arc is connected to the outlet end of the track 4. At the tip of this support rail 5, there is an inner guide plate 6.
and an outer guide plate 7 are arranged so as to form a guide groove 8 of uniform width between them.

Thus, an arcuate vertical guard 9 is installed between the outlet of the track 4 and the inlet end of the inner guide plate 6. 2. The vertical guard 9 is formed by curving a long thin plate of uniform width into an arc shape, and a capacitor 10 is attached to the lower edge of the vertical guard 9.
A gap 11 is formed through which the lead wire 1.0a can protrude outward. In FIG. 1, reference numeral 11 indicates a deflection plate, and the capacitor 10, which is vibrated and transported in the direction of the arrow on the support rail 5, is converted into an upright position with its head facing upward, and is moved to the guide groove 8. Guided within.

Additionally, at the outlet ends of the inner and outer guide plates 6 and 7,
A linear feeder 12 is connected, and this linear feeder 12 is provided with a guide groove 14 along the longitudinal direction at the center of the feeding track 13.
As is well known, a vibration generator including an excitation electromagnet and a leaf spring is installed in the lower central part of the feed track 13, and when the electromagnet is excited, it causes the capacitor 10 on the feed track 13 to move in an arrow direction. It can be sent in the visual direction.

According to the present invention, an annular magnet 15 is disposed outside the vibrating bowl 1 so as to concentrically surround it. This annular magnet 15 has a large number of magnet rubber pieces 16 butted back and forth to form an endless ring as a whole.

These magnetic rubber pieces 16 have an annular receiver accommodated in a groove 17, and the annular receiver has a groove 17 connected to the side wall of the vibrating bowl 1 via a connecting wall 18, as shown in FIG. are connected together.

Further, the annular magnet 15 is arranged at each of the 'A-A position, the B-B position, and the C-C position so that the attraction surface 16a of the magnetic rubber piece 16 can attract the lead wire 10a of the capacitor 10 in the axial direction. The direction is changing. Therefore, the double magnet rubber piece 16 receives vibration from the vibration generator 2 of the vibrating bow 1 and moves in the direction of the arrow in synchronization with the transfer speed of the condenser 10.

Since the present invention is configured as described above, when the vibration generating device 2 of the vibratory bowl feeder device is excited and driven, the condenser 10 in the vibrating bowl 1 moves from the inside to the outside along the track 4. Vibratory transport. Near the exit of the track 4, the capacitor 4 is influenced by the attraction force by the magnet rubber piece 16 of the annular magnet 15 rotating counterclockwise, and the lead wire 10a protrudes outward.
While suctioning the tip of 0a, it is transferred in the direction of the arrow.

While being transported on the support rail 5, the condenser 10 is temporarily changed from a horizontal position to a vertical position. after that,
The condenser 10 passes inside the deflection plate 11 and is fed along the groove 8 between the inner and outer guide plates 6 and 7 and is delivered by the linear feeder 12.

〔Effect of the invention〕

As is clear from the explanation of Yu, according to the present invention, an annular magnet is provided on the outside of the vibrating bowl concentrically therewith, and the annular magnet is rotated synchronously by the vibration generator of the vibrating bowl feeder. It is possible to transport electronic components such as heavy capacitors extremely smoothly by vibration without dropping them into the vibration bowl, and without applying braking to the lead wires.
