Abstract

PROBLEM TO BE SOLVED: To open an upper part of a jig when a tool ascends by automatically oscillating the tool installed on a vertically moving table according to vertical motion of the vertically moving table. SOLUTION: An upper part of a unit 51 grasps a work 20 from a jig 61 attached to a turntable 3 according to a descent of a vertically moving table 1. Next, when the vertically moving table 1 and a tool 4 (the unit 51) are raised while gripping the work 20, the tool 4 (the unit 51) ascends, and starts to oscillate by an inclined member 53 sliding along a guide roller 55 from a constant height, and operates to push the work 20 outward. At this time, the work 20 is rotated by a driving motor. Grease is uniformly applied to the work 20 by this rotational operation. Afterwards, the unit 51 returns the grease-applied work 20 to the former jig 61 by performing operation in a prescribed locus.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a base column type automatic machine or a base machine for an automatic assembling machine according to the present invention.

FIGS. 1 to 3 show an embodiment of a base machine for a center column type automatic machine according to the present invention.

In FIG. 1, reference numeral 1 denotes a vertically movable table, which is supported by a vertically movable column 2. The column 2 is disposed outside the turntable 3 that is intermittently driven via an output section of the intermittent drive device, and slides inside the bearing 6.

As described above, the vertically movable table 1 includes the support 2
Supported by. The column 2 is guided by a bearing 6 and has a roller (not shown) provided at a lower portion thereof, and is in contact with a cam (not shown) driven by a drive motor (not shown). When the roller is in the lower part of the cam, as the cam rotates, the roller moves to the higher part of the cam and is pushed upward. Of course,
The column 2, the vertical table 1, and the tool 4 attached to the vertical table 1 are also pushed upward, and the jig 5 and the tool 4 on the turntable 3 are separated.

In this state, the turntable 3 is attached to the jig 4
It moves intermittently by the pitch. The cam continues to rotate during the intermittent movement of the vertically moving table 1, and when the intermittent movement is completed, the vertically moving table 1 and the tool 4 are lowered.

A tool 4 is mounted on the vertically movable table 1. Tool 4 is a punch for caulking, a screwdriver,
Drills, markings, adhesive discharge nozzles, work take-out devices, work supply devices, etc.

The tool 4 shown in FIG. 1 is a unit 51, which is attached to a rotating shaft 52 provided on the vertically movable table 1 via a tilting member 53 so as to swing freely. This inclined member 5
The arm 3 has an arm 54 extending toward the column 2 at the lower part of the side surface, and a predetermined arc-shaped inclined surface is formed along the arm 54 from a vertical side surface.

On the other hand, the end of the intermediate table 31 is provided with a guide roller 5 which comes into contact with the inclined member 53 of the unit 51.
5 is attached. Therefore, the inclination member 5 is moved along the guide roller 55 as the vertically moving table 1 rises.
3 slides first and rises vertically. Next, the inclined surface of the inclined member 53 approaches the guide roller 55, and the inclined member 53 moves to the tip end side of the arm 54 along the guide roller 55. That is, unit 5
Numeral 1 swings around the rotation shaft 52.

When the above-described operation of the unit 51 is viewed at the tip thereof, it first rises vertically, and when it has risen a certain distance, starts moving outward from the turntable 3.
At the end it is suddenly pushed out.

In the drawing, reference numeral 56 denotes a return spring, one end of which is located on the side of the vertical movement table 1 and the other end of which is the rotary shaft 5 above the inclined member 53.
It is attached to a lever 57 protruding from the opposite side of the second member 2 to bring the inclined member 53 into close contact with the guide roller 55.

The work 20 is mounted in the jig 5 on the turntable 3 by hand or by a supply device. Some of the jigs 5 on which the works 20 are mounted are mounted on the turntable 3. The turntable 3 is intermittently driven via an output section of the intermittent drive device. That is, the turntable 3 repeats moving and stopping the same number of times as the number of the jigs 5 per table rotation.

The operation of the above embodiment will be described with reference to the grease application shown in FIG. The unit 51 grasps the work 20 from the jig 61 attached to the turntable 3 at the position shown by the solid line as the vertically moving table 1 descends.

Next, when the vertically moving table 1 and the tool 4 (unit 51) are raised while holding the work 20, the tool 4 (unit 51) starts swinging from a certain height after rising, and moves outward. The work 20 is pushed out. At this time, the work 20 is rotated by the drive motor. The grease is uniformly applied to the work 20 by this rotation operation.

Reference numeral 62 denotes a device for applying grease to the work 20. Reference numeral 64 denotes a syringe for storing grease, which applies grease to the work 20 via a coating head 63.

Thereafter, the unit 51 performs an operation along a predetermined locus to return the grease-applied work 20 to the original jig 61.

In the embodiment of FIGS. 4 and 5, the unit 5
The work 20 'is gripped by the chuck pawl 74 provided below 1'. Next, the slide member 72 provided on the unit 51 'slides along the slide guide 73 provided on the inclined member 53. Therefore, the work 20 'in the jig 5 attached to the turntable 3 moves upward and is largely swung outward.

Thereafter, when the chuck jaws 74 are opened at the point where the chuck jaws 74 are swung to the outside most, the work 20 ′ is indicated by an arrow 7.
It is thrown out in the direction of 5 and falls. Since the work 20 'can be taken out of the jig 5 in this manner, it can be suitably used for an automatic take-out device of an automatic assembling machine.
