Abstract

PROBLEM TO BE SOLVED: To transfer even a component laminately coated with synthetic resin on the external surface smoothly at high speed by forming a plurality of projecting stripes in parallel along the transfer direction on the bottom face of a trough, and transferring the component by means of vibration while contacting with the projecting stripes. SOLUTION: A component (m) is transferred in a trough 1' while repeating small jump motion. Further, even when it is contacted with both inside walls 1b of the trough 1', large suction force due to static electricity is not generated, because it is line contact, and the clearance between the walls and the component is kept in a fixed distance. On the bottom face (ma), the component is transferred while only contacting with a pair of projecting stripes 10a, 10b, but suction force is small even if static electricity is generated, and hence, the component can be smoothly transferred at desired high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration component supply device.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional linear vibration parts feeder. A linear trough 1 is connected to a base block 2 by a pair of front and rear inclined leaf springs 3. A movable core 4 is fixed to the bottom surface, and an electromagnet 5 is fixed to the base block 2 with a gap therebetween. The base block 2 is supported on the ground by an anti-vibration rubber 6. When an alternating current is applied to the electromagnet 5, the trough 1 vibrates in the direction indicated by the arrow a as is known. Thereby, the components in the trough 1 are transported to the right in the figure, but it is now assumed that components m as shown in FIGS. 1 and 2 are transported. This part m has a bottomed cylindrical shape, a diameter D of about 5 mm, a height H of about 4 mm, made of aluminum, and the surface thereof is laminated and coated with a synthetic resin. FIG. 2 is an enlarged cross-sectional view of a part of this. The surface of a main body k made of aluminum is coated with a synthetic resin g by a known method.
When such a part m is transferred by vibration on the trough 1 of the above-mentioned linear vibration feeder, the trough 1 has a U-shaped cross section as shown in FIG. 7 (where 7 is a holding plate). There is a slight gap in the bottom
a is transferred by vibration in a state in which it abuts on (a small jumping motion is applied), but because the surface is laminated and coated with synthetic resin, static electricity is generated due to this, and high-frequency vibration causes small amplitude In the case (the direction of the arrow a in FIG. 6, that is, the vibration angle is considerably large, but in such a case, it is further reduced. In order to make the figure easier to understand), in particular, the attraction force due to this electrostatic force. However, there is a case where the part m is not transported because the part m is light metal and has a greater inertia due to vibration.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a vibration component supply device capable of smoothly transferring even the above-mentioned components by vibration.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to provide a vibrating component feeder which is made of a light metal and whose outer surface is laminated and coated with a synthetic resin along a track by vibration. A vibration component supply device is characterized in that a plurality of parallel ridges are formed on a bottom surface along a transfer direction, and the components are transferred by vibration on the ridges.

[0005] Even if the trough vibrates at a high frequency with a small amplitude, or even if the outer surface is a component laminated with a synthetic resin, only the ridges formed on the bottom wall of the truck have the bottom surface of the outer surface. Is transported by vibration while abutting against. As a result, it is possible to supply the next process at a desired speed at a high speed and smoothly.

[0006]

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

The part m to be applied is an aluminum cap as shown in FIGS. 1 and 2, and the outer surface thereof is made of a synthetic resin g.
Laminated coating. As the outer shape, a linear vibration feeder similar to the linear vibration feeder 6 of the conventional example is applied, but a trough 1 ′ as a track thereof has a center line of the trough 1 ′ on a bottom surface 1a ′ as shown in FIG. That is, a pair of ridges 10a, 10a
b is formed. The part m is transported in the trough 1 'while repeating a small jumping movement on this.
Since the inner side walls 1b of the trough 1 'are in line contact even if they come into contact with each other (although the relationship is the same as in the related art), even if static electricity is generated, there is a gap between them and the part m. Since it has a size and is in line contact even when it comes into contact, it does not generate a large attractive force due to static electricity. Bottom m
In (a), the transfer is performed while abutting only on the pair of ridges 10a and 10b. Even if static electricity is generated, the suction force is small, and the transfer can be performed smoothly and at a desired high speed.

FIG. 4 shows another embodiment. In this embodiment, a spiral-type vibrating parts feeder 20 is applied. , 25b, on which the parts m are subjected to torsional vibrations (although they have not been transferred by being sucked to the flat bottom surface of the truck in the past), according to the present embodiment, And at the desired high speed. The driving unit of the vibrating parts feeder 20 is the same as the conventional one, but in the present embodiment, it is a so-called high-frequency part and has an amplitude of 0.2 Hz at 220 Hz.
3 mm. (The vibration angle is very small at about 5 degrees.) Under such vibration conditions, the transfer can be performed smoothly and at a high speed as described above. According to the present embodiment, the ridges 25a and 25b are roughened by blasting glass beads or sand of 80 to 150 mesh, but the ridges 25a and 25b can be further blasted at a higher speed than when the surface is not roughened. Can be transported.

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

For example, in the above-described embodiment, a pair of ridges 10a, 10b, 25a,
25b is formed and the bottom surface is brought into contact with the
Is transferred by vibration. Of course, the number of the ridges may be three or more, and may be determined according to the size of the bottom surface of the component. The present invention has a great effect when the component m is made of a light metal, but may be made of a light metal other than aluminum, for example, copper or another light metal. Further, in the above embodiment, the outer surface of the component m is laminated and coated with a synthetic resin, but of course, the present invention can be applied to all components coated with a material made of a dielectric material instead of a synthetic resin. It is. Therefore, the synthetic resin in the claims includes other materials that are dielectrics.

Further, in the above description, the parts have a cylindrical shape with a bottom. However, the present invention is not limited to this, and all parts made of a light metal whose outer surface is coated with a dielectric material or a synthetic resin are applicable to the present invention. Is applicable. For example, it may have a rectangular parallelepiped shape or a pyramid shape, which is effective for a part whose bottom surface contacts the track surface with a large area.

Further, in the above-described second embodiment, 22
A so-called high-frequency vibrating parts feeder is applied at 0 Hz and 0.3 mm in amplitude, but of course, the present invention can also transfer at a lower transfer frequency and a larger amplitude at a higher transfer speed than before. However, at a frequency higher than the so-called commercial frequency of 50 Hz or 60 Hz, for example, 100 Hz or 120 Hz which is twice that frequency, 50H
z, more effective than 60 Hz, and particularly effective at high frequencies of 100 Hz or more. In general, the amplitude is 0.3
Although it is very small and the vibration angle is small at about mm or less, it is particularly effective for a track vibrated under such vibration conditions.

In the above embodiment, the linear vibration feeder is not blasted with glass beads or sand. Of course, these ridges 10a, 10b
Blasting with glass beads or sand (80
(150 mesh) can be transferred at a higher speed.

[0014]

As described above, according to the vibration component supply apparatus of the present invention, even if the outer surface is a component whose outer surface is laminated and coated with a synthetic resin, or even if the vibration has a high frequency and a small amplitude. It can be transported smoothly and at high speed.
