Abstract

PROBLEM TO BE SOLVED: To prevent a part item put in a bowl from being put on the head of a mounting bolt and staying within the bowl by providing a mounting bolt upward boss in the center of the bottom of the bowl, and setting the upper seat surface of the boss to a position higher than the putting position of the part item to the bowl. SOLUTION: Upper and lower vibrating bodies 1, 2 are vibratingly connected through a plate spring 3, and a bowl 4 put on the upper surface center of the upper vibrating body 1 is fixed by a mounting bolt 5. A movable iron core and an electromagnet are integrated to the upper and lower vibrating bodies 1, 2, respectively, and the bowl 4 is twisted and vibrated by applying an AC power to the electromagnet to transfer a part put into the bowl 4 along a spiral track 6 provided on the inside surface thereof. In such a part feeder, a boss 7 for the mounting bolt 5 is provided in the center of the bottom of the bowl 4. The upper seat surface of the boss 7 is set to a position higher than the putting position of the part to the bowl 4 to prevent the part from being put on the upper seat surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a vibratory component supply apparatus using a bowl, as shown in FIG.
The center portion is fixed to the upper vibrating body 23 that vibrates torsionally.
Therefore, the bowl 21 is also torsionally oscillated about the central portion fixed by the bolts 22, and the components put into the bowl 21 are transferred along the spiral track 24 from the bottom of the bowl 21 with the torsion oscillation. And supplied to the next step.

[0003] The components to be put into the bowl 21 are put into the bottom of the bowl 21 from a carrying container or the like, and a part of the component is put on the head of a flat bolt 22. Bowl 21
Since the amplitude of torsional vibration is small at the head of the bolt 22 located at the center of the bolt 22, there is a problem that components placed on the head of the bolt 22 stay as they are and do not enter the track 24 provided on the inner peripheral surface.

To address this problem, Japanese Patent Laid-Open No. 10-2
In the vibration type component supply device disclosed in Japanese Patent Application Laid-Open No. 12013/2003, as shown in FIG.
A cap 27 having a conical tip is attached to and fixed to the head of No. 6 and covers a flat bolt 26 head so that the component 28 does not stay here.

However, the cap 27 of the above-mentioned separate part is
However, there is a problem that the outer surface of the conical shape and the inner surface fitted into the bolt 26 have complicated processing shapes, and the manufacturing cost increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inexpensive vibration-type component supply device capable of preventing components from remaining in a bowl.

[0007]

In order to solve the above-mentioned problems, the present invention relates to a method in which an upper vibrating body and a lower vibrating body, which are vertically arranged opposite to each other, are connected by a leaf spring, and the upper vibrating body is vibrated. In a vibratory component supply device, the component is torsionally vibrated by means, the bowl is fixed to the upper vibrator with bolts, and the component to be put into the bowl is transported and supplied along a spiral track provided on the inner peripheral surface of the bowl. An upward boss for the mounting bolt is provided at the center of the bottom of the bowl, and the upper seating surface of the boss is set at a position higher than a position where components are put into the bowl.

In other words, a boss for a mounting bolt is provided at the center of the bottom of the bowl, and the upper seating surface of the boss is set at a position higher than the position at which the component is put into the bowl. On the head.

[0009] The boss for the mounting bolt may be formed of a separate cylindrical member.

[0010] By forming the inner bottom surface of the bowl with an inclined surface descending from the center side to the outer peripheral side around the boss, parts of the bowl bottom can be quickly moved along the inclined surface along the spiral track. Can be moved to the entrance.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment. The vibrating component supply device includes an upper vibrating body 1 and a lower vibrating body 2
Are vertically coupled by a leaf spring 3, and a bowl 4 is fixed to a center of the upper surface of the upper vibrating body 1 with mounting bolts 5. Although not shown, a movable iron core and an electromagnet are incorporated in the upper vibrating body 1 and the lower vibrating body 2, respectively. By connecting an AC power supply to the electromagnets, the bowl 4 torsional vibrates together with the upper vibrating body 1, 4 are transferred along a spiral track 6 provided on the inner peripheral surface.

At the center of the bottom of the bowl 4, a boss 7 for the mounting bolt 5 is provided, and the upper bearing surface of the boss 7 through which the head of the bolt 5 is received via the washer 8 is provided.
It is provided at a position higher than the position at which components are put into the device.
Further, the bottom surface of the bowl 4 around the boss 7 is formed by an inclined surface 9 descending from the center side to the outer peripheral side, so that the inserted parts can be moved to the lower end entrance of the truck 6 quickly.

FIG. 2 shows a second embodiment. This vibration-type component supply device has the same basic configuration as that of the first embodiment, except that the boss 7 for the mounting bolt 5 is formed of a separate cylindrical member 10.

[0014]

As described above, in the vibration type component supply device of the present invention, the boss for the mounting bolt is provided at the center of the bottom of the bowl, and the upper seating surface of the boss is located at a position higher than the component input position to the bowl. , The components put into the bowl can be prevented from resting on the head of the mounting bolt and remaining in the bowl.

Further, by forming the inner bottom surface of the bowl with an inclined surface extending from the center side to the outer peripheral side around the boss, parts of the bowl bottom can be quickly spirally formed along the inclined surface. Can be moved to the entrance of the truck.
