Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus for moving components between processes when processing components.

[0002]

2. Description of the Related Art In a processing workplace for processing parts,
In a line in which processing machines are arranged, it is common that a part being processed is transported between machines by handling of an operator.

[0003] The techniques of Japanese Patent Application Laid-Open No. 5-139535 and Japanese Utility Model Application Laid-Open No. 55-41253 are also known.

[0004] However, the above-mentioned technique has a problem that heavy heavy work is performed and heavy lifting is required. In addition, in the case of a large-sized transfer device, when a part to be processed is changed, it is troublesome to change the setup, which is a troublesome operation.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the attendant work of an operator when moving parts between processes,
An object of the present invention is to provide a component supply device that has a simple structure, does not require power, and does not require heavy-weight work.

[0006]

According to the present invention, an arm is provided at the upper end of a vertical column so as to be pivotable, and the arm is pivoted in a component supply apparatus for moving a component between processes in the case of machining a component. The shaft is inclined toward the destination where the component is to be conveyed, a weight is provided in the extension direction opposite to the arm, and a stopper is provided so as to restrict the turning range of the arm.

Further, according to the present invention, it is preferable that a damper is attached to the stopper, and that an angle changing means for changing a tilt angle of the pivot axis of the arm be provided. Needless to say, it is not necessary to provide the angle varying means. In this case, the pivot axis is fixed to the upper end portion of the vertical column at an inclined angle directly by welding or the like without passing through the angle varying means.

The present invention is constructed as described above, and the operator simply places the component to be moved on the component receiver, eliminating heavy weight work, eliminating walking loss, and generating no dedicated power, thereby improving efficiency. It is safe because fatigue is also reduced.

FIG. 2 shows the revolving portion 15. Tapered roller bearings 3, 2 are respectively fitted into a cylindrical bearing case 1 from above and below, and a shaft 5 having a flange 4 is mounted from below the bearing case 1. Installed. A cover 6 is fastened to the upper end of the shaft 5 with a nut 7, and a connection shaft 11 of an angle varying device 10 as angle varying means is welded to the flange 4. And
The arm 8 is welded to the case 1, and the stay 9 to which the weight 9 a is screwed is screwed into a screw hole 9 a provided in the case 1 on an extension of the opposite side of the arm 8.

A plate 35 is welded to the lower side of the connecting portion between the arm 8 and the bearing case 1 so that the connecting shaft 11
The first bracket 36a provided on the
The stopper 37 is supported so that the tip 37a slides with the stopper 37 and the rod 37b that reciprocates is buffered by a stored spring (not shown). . The first
4, the second bracket 36b is similarly provided at an angle of about 90 degrees with the first bracket 36a.

FIG. 3 shows the angle varying device 10 and the connecting shaft 1.
1 has a first plate 20 fixed thereto, and the column 12 has a second plate 20 fixed thereto.
Plate 21 is fixed. Hinges 29, 29 are provided on one side of the first plate 20, and hinges 30, 30 are provided on the corresponding one side of the second plate 21.
The first plate 20 and the second plate 21 are rotatable about a pin 31 at 2.

Further, grooves 26, 26 are provided on the other side opposite to one side of the first plate 21, and a spherical surface 26a is formed on the upper surface of the grooves 26. The first and second plates are The spherical seat 27 is connected to the bolt 28 and the screw hole 23 via the spring 27, and the screw hole 24 provided in the second plate 21 is provided.
And the bolt 25 to be screwed into the first and second plates 2
The mutual inclination angles of 0 and 21 can be adjusted, and the angle between the column 12 and the connection shaft 11 can be changed in one direction (right front and left rear in the figure).

The operation will be described below with reference to FIG.

In FIG. 4, a description will be given on the assumption that a processing machine (not shown) is installed at a position A and a position B, and a part being processed moves from the position A to the position B.

First, at the time of operation, the base 13 is installed on the component supply device T such that the inclination of the connection shaft 11 of the angle varying device 10 is directed to the position B. Then, the angle between the first and second plates is adjusted with a bolt 25 for adjusting the angle to a required angle, and fixed with a bolt 28.

Further, an attachment (not shown) is attached to the component receiver 8a according to the shape of the component, and the weight of the arm 8 including the component receiver 8a and the weight of the attachment and the work which are measured in advance are larger than the weight of the weight. The weight of the arm whose weight is smaller than the weight of the weight is selected, and the preparation for attachment to the stay 9 is completed.

In this state, at the position A, the component receiver 8a
When a component is placed on the (attachment), the arm 8 side is heavier than the weight 9 side, and the connection shaft 11 is inclined in the direction of the position B, so that the component receiver 8a is rotated counterclockwise.
As indicated by 1, the plate 35 comes into contact with the stopper 37 of the bracket 36b at the position B and the rotation stops. Therefore, the part can be moved from the position A to the position B, and requires no manpower and power. If a part is taken, the weight is heavier on the weight side than on the arm side, so the part receiver 8a rotates clockwise like C2 and returns to the position A, and thereafter the above operation is repeated. Since the stopper has a built-in damper, there is no impact when the arm 8 is stopped, and it is safe to use heavy parts.

FIGS. 5 and 6 show an embodiment without an angle varying device. The shaft 5 is welded to the tip of the vertical column 12A with an inclination angle θ without passing through an angle varying device, and the revolving part 15 is provided so as to be revolvable and can be operated in the same manner.

[0021]

The present invention is constructed as described above, and the operator merely places the component to be moved on the component receiver, eliminating heavy-weight work and eliminating walking loss, thereby improving efficiency.
Fatigue is reduced and it is safe. In addition, no dedicated power is required for moving parts.
