Abstract

PURPOSE:To provide a work aligning and supplying device in which attitude abnormality of works can be coped with, and in which the works can be aligned or supplied at a high speed in aligning or supplying 90deg. curved pipe joints in right/left symmetric directions. CONSTITUTION:A device is provided, with a work 1 attitude determination sensor 3, a work holder 2 having a work inverting device 4 which is capable of rotation and oscillation in a horizontal plane, and a magazine 6 having stoppers 7a, 7b provided above the work holder 2. When a work 1 drops from the magazine 6 to the holder 2, an attitude of the work 1 is determined, and the attitude of the work 1 is corrected to be normal by the work inverting device 4, thereby the works 1 can be aligned or supplied in right/left symmetric directions at a high speed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aligning and supplying 90 ° curved pipe joints, and more particularly to an apparatus for aligning or supplying in a symmetrical direction at a high speed.

[0002]

2. Description of the Related Art There are the following methods for aligning or supplying 90 ° curved pipe joints (hereinafter simply referred to as "work") as shown in FIG. (1) As shown in FIG. 6, two sets of magazines having a plurality of stoppers are provided, and the works are attached to the respective magazines so that the directions of the work are symmetrical, and the plurality of stoppers are provided. Alternately operating the work to align or supply the work in a symmetrical direction. (2) A method of gripping the positioned works one by one and aligning or supplying the works at a predetermined position in a predetermined direction by a robot or the like provided with a work gripping, turning, and swinging mechanism.

[0003]

In the above-mentioned conventional aligning and feeding apparatus, the method (1) has a simple structure and is inexpensive, but the work mounted in the magazine is stoppered.
Since it is dropped and supplied one by one by switching, the work may be reversed as shown in FIG. 3 when dropping.

In the method (2), since the work is gripped,
Since it is necessary to position the work by aligning the work in a grippable posture and direction, it takes time to control the posture, and in order to grip and feed the work one by one, the alignment supply time per one is required. become longer.

As described above, the present invention is to provide a device capable of coping with an abnormal posture of a work and supplying or arranging and supplying 90 ° curved pipe joints in a symmetrical direction at a high speed at a high speed. It is intended.

[0006]

SUMMARY OF THE INVENTION The present invention is a work holder having a work attitude determination sensor and a work reversing device, and a work holder for swinging and swinging in a horizontal plane. A magazine with a plurality of stoppers is provided above the holder so that when the work falls from the magazine to the holder, the work is
This is an aligning and feeding device which determines the posture of a work and normalizes the work posture by a work reversing device to align or feed the work in a symmetrical direction at a high speed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the overall configuration of the present invention will be described. In FIG. 1, reference numeral 2 denotes a work holder into which one work 1 shown in FIG. 5 can be inserted. As shown in FIG. 2, a work posture determination sensor 3 and a work reversing device 4 are provided on the side surface. There is. The work holder-2 can be swung by a turning device 5 in a horizontal plane. Further, in FIG. 1, a magazine 6 is provided above the work holder-2, and a magazine 6 is provided on the side surface thereof.
As shown in FIG. 3, stoppers 7a and 7b for supplying the work 1 to the work holder 2 one by one are provided.

Next, the operation of the device of the present invention will be described. First, the work 1 is supplied to the magazine 6 by a supply device (not shown), and stoppers 7a and 7b below the stoppers 7a and 7b provided on the side surface of the magazine 6 as shown in FIG.
A plurality of works 1 are mounted above the. Then stopper
The second work from the bottom is fixed in the magazine 6 by 7b, the stopper 7a is released, and the first work is dropped and supplied to the work holder-2. As shown in FIG. 2, the work 1 is received by the work reversing device 4, and the work attitude determination sensor 3 provided on the side surface of the work holder 2 determines the attitude of the work 1. If the posture of the work 1 is normal,
The work reversing device 4 is retracted in the direction A as shown in FIG.
Supply 1 by dropping it directly below. When the posture of the work 1 is abnormal, the work reversing device 4 is turned in the direction B as shown in FIG. 3, the work 1 is reversed 90 degrees, and the work 1 is dropped and supplied directly below.

Next, after the stopper 7a is operated, the stopper 7b is released, and the work 1 is dropped in the magazine 6 by one amount. Then, similarly to the above, the second work from the bottom is fixed in the magazine 6 by the stopper 7b, the stopper 7a is released, and the first work is moved to the work holder-2.
To supply. After the work 1 is received by the work reversing device 4 and the work holder 2 is turned 180 degrees in the horizontal plane by the turning device 5, the attitude of the work 1 is determined by the attitude determination sensor-3. , If the posture of the work 1 is normal, the work reversing device 4 is retracted in the direction A, and the work 1 is dropped and supplied directly below. If the posture of the work 1 is abnormal, -The work reversing device 4 is swiveled in the direction B, the work 1 is reversed 90 degrees, and the work 1 is dropped and supplied directly below. Further, the turning device 5 turns the work holder-2 again by 180 degrees in the horizontal plane to return it to the original position, and the above operation is repeated.

[0010]

INDUSTRIAL APPLICABILITY The present invention has the following effects in an apparatus for aligning and feeding 90 ° curved pipe joints, particularly for aligning or feeding in a symmetrical direction at high speed. Vertically feed the work from the magazine to the work holder,
In the work holder, the posture discrimination sensor discriminates the posture of the work, and the work reversing device detects that the posture is abnormal.
Since the posture of the work can be returned to a normal state and the work can be swung and oscillated in the horizontal plane, the work can be aligned or supplied at a high speed in symmetrical directions.
