Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for aligning or feeding 90 ° curved pipe joints in symmetrical directions at high speed.

[0002]

2. Description of the Related Art Conventionally, (1) two sets of magazines 2 having a plurality of stoppers 3a and 3b are provided as shown in FIG.
The works 1 are mounted in the respective magazines 2 so that the 90 ° curved pipe joints (hereinafter referred to as the works 1) shown in FIG.
The workpieces 1 were arranged or supplied in a bilaterally symmetrical direction by alternately operating. Alternatively, (2) workpieces positioned by a robot or the like provided with a workpiece gripping, turning, and swinging mechanism are gripped one by one and aligned or supplied at a predetermined position in a predetermined direction.

[0003]

The above-mentioned conventional alignment supply (1) has a simple structure and is inexpensive, but
It is necessary to preliminarily align the works to be mounted on the magazines in the pair in symmetrical directions, and when the works are mounted in the magazine in an abnormal posture, they are supplied in the wrong orientation.

In (2), since the work is gripped, it is necessary to align and position the work in a grippable posture and direction, and it takes time to control the posture, and the work is gripped one by one and aligned and supplied. Therefore, the alignment supply time per unit becomes long.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the conventional example, and to provide a work aligning / feeding device capable of coping with an abnormal posture of a work and capable of aligning or feeding in symmetrical directions at high speed.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a work posture determining device having a plurality of stoppers and a plurality of sensors and a work discharging device are provided at the upper part of a magazine, and the posture of a work supplied to the upper part of a magazine and a posture abnormal work are provided. The discharge of
A feature is that a work holder that swings and swings in a horizontal plane is provided below the magazine to distribute the works, and the works are aligned or supplied at a high speed in symmetrical directions.

[0007]

Embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5 and 7. 1 is a front view of the work aligning and feeding device, FIG. 2 is a perspective view of a magazine unit, FIG. 3 is a perspective view of a work holder, FIG. 5 is a perspective view of a work, and FIG. In FIG. 1, reference numeral 2 denotes a magazine in which the works 1 enter vertically in one row, and a sensor 4 for detecting the presence or absence of the works is provided on the lower side surface thereof, and the works 1 are sent out one by one as shown in FIGS. Stoppers 3a and 3b are provided for this purpose. As shown in FIGS. 1 and 2, a work posture determining device 20 including three proximity sensors 5a, 5b, 5c for detecting the presence or absence of a work and a stopper 6 and a rotating device 7 are provided above the magazine 2.
A work discharge device 21 including the rotary plate 8 and the rotary plate 8 is provided. Below the magazine 2, there is provided a work holder 9 into which one work 1 is inserted, and a swivel device 10 enables swiveling and swinging in a horizontal plane. Reference numeral 11 denotes an opening / closing hand that swings and swings together with the work holder 9 by the swivel device 10. As shown in FIG. Has been.

Next, the operation will be described. The work 1 is supplied to the magazine 2 by a supply device (not shown),
As shown in FIG. 5, the stopper 6 is temporarily fixed by the stopper 6 provided on the upper side surface of the magazine 2. In this state, the sensors 5a, 5b, 5
The presence or absence and the posture of the work 1 are checked by c. As shown in FIG. 7, when the combination of the sensor detection states is (a), the stopper 6 is released and the work 1 is dropped below the magazine 2. Otherwise, as shown in FIG. 7
The rotating plate 8 is rotated in the direction of the arrow to discharge the work 1 out of the magazine 2.

The works 1 in the correct posture when they are released by releasing the stopper 6 are stacked above the stopper 3b. After the sensor 4 detects the presence or absence of the work immediately above the stopper 3b, the stopper 3a stops the second and subsequent works 1, and subsequently releases the stopper 3b to release the first work 1.
Are dropped and supplied to the work holder 9. The work 1 supplied to the work holder 9 is dropped and supplied directly below by opening the claw 12. After confirming the drop of the work 1 by the sensor 4, the claw 12 is closed.

Next, after the stopper 3b is operated, the stopper 3a is released and one work 1 is dropped in the magazine 2. Then, similarly to the above, the second and subsequent works 1 from the bottom are stopped in the magazine 2 by the stopper 3a, the stopper 3b is released, and the first work 1 is dropped and supplied to the work holder 9. Further, the work holder 9 is rotated 180 ° in the horizontal plane by the revolving device 10, the pawl 12 is opened, and the work 1 is dropped and supplied immediately below. Then, the claw 12 is closed, and the work holder 9 is turned again by 180 ° in the horizontal plane to return to the original position, whereby the operation of one cycle is completed. The above series of operations is repeated.

As described above, according to the present invention, it is possible to cope with the abnormal posture of the work, and to supply the work symmetrically and at high speed.
