Abstract

PURPOSE:To convey an article to be conveyed to a specified position while keeping a specified posture unchanged in a simple structure bay providing a pair of supporting mechanisms which move both ends of the rail bodies up and down and a movable carriage capable of freely moving in the longitudinal direction of rail bodies with the article placed thereon in the specified posture. CONSTITUTION:When a workpiece W is placed on a movable carriage 2 and the driving rod 6a is extended with the driving rods 6a and 6b of supporting mechanisms 5a and 5b retracted, rail bodies 1 are inclined rightward. At this moment, the air cylinder 4 on the supporting mechanism 5a is driven to protrude a driving rod 4a, a hook 4b releasing the movable carriage 2 and giving the movable carriage 2 initial speed. When the movable carriage 2 moves toward the supporting mechanism 5b, and is held by the hook 4b, the driving rod 6a of the supporting mechanism 5a is retracted, the rail body 1a is kept horizontal again. The workpiece W is conveyed to a specified position by means of an automatic handling device 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device, and more particularly,
The present invention relates to an object that can be easily transported to a predetermined position while maintaining a predetermined posture.

[0002]

2. Description of the Related Art Conventionally, a belt conveyor has been known as an apparatus for conveying an object to be conveyed. In this belt conveyor, an endless belt is stretched between a pair of right and left rollers, and one roller is driven by a motor to drive an endless belt. Then, the transported object is placed and moved on the belt conveyor.

[0003]

However, in the above-mentioned conventional belt conveyor, since the object to be conveyed is simply placed on the belt conveyor and moved, the posture of the object to be conveyed at the end of movement is fixed. Therefore, it cannot be handled from the belt conveyor by the automatic handling device. In order to be able to handle the transported object on the belt conveyor with an automatic handling device, the belt conveyor should be provided with a large number of supports for holding the transported object in a predetermined posture, and the support table should be placed at a predetermined position. It is necessary to perform the intermittent drive control so as to stop the drive of the motor at the time of reaching, and there is a drawback that the device becomes complicated and the cost increases.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object thereof is to provide a transfer device capable of transferring an object to be transferred to a predetermined position while maintaining a predetermined posture. It is in.

[0005]

In order to achieve the above-mentioned object, a device of the present invention has a rail body having a length from a movement start point position to a movement end point position of an object to be conveyed, and both end sides of the rail body. And a pair of support mechanisms for respectively supporting each of them and vertically moving the respective end sides thereof, and a movable base provided to mount the transported object in a predetermined posture and movable in the longitudinal direction of the rail body. It is characterized by having and.

[0006]

In the above structure, when one of the support mechanisms raises the rail body, the rail body tilts. This allows
The moving table on which the transported object is placed moves to the other supporting mechanism side on the rail body. The movable table that has been emptied by taking out the transported object raises the other supporting mechanism to incline the rail body in the opposite direction to the above, and moves it to one supporting mechanism side.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an operation state of the apparatus of one embodiment.

FIG. 1A shows a state in which the rail main body 1 is kept horizontal and the movable table 2 is present at the movement start point a on the left end side of the rail main body 1. The rail main body 1 has a length such that a cast bell-shaped insulator cap metal (hereinafter, referred to as a work) W, which is an object to be transported, can be moved from a movement start point a to a movement end point b.
As shown in, the pair of rail pieces 1a and 1b are arranged with a predetermined interval. As shown in FIG. 2, the movable table 2 has a main body portion having a pair of rail pieces 1a and 1b.
The rollers 3, 3 ... Between which are provided rotatably on both sides, are mounted on the pair of rails 1a, 1b. Further, the upper surface of the support base 2 is provided with a recess capable of receiving the bowl portion of the work W,
Can be placed in a predetermined posture. Therefore, when the rail body 1 is tilted, the support base 2 can move the work W while maintaining a predetermined posture.

Drive rods 4 are provided on both ends of the rail body 1.
Air cylinder 4 in which a is provided parallel to the upper surface of the rail body 1
Are provided respectively, and are configured to hold the support 2. That is, the drive rod 4 of the support base 2
Ear pieces 2a having openings are provided on both side walls facing a, respectively, so that they can be engaged with hooks 4b provided at the tip of the drive rod 4a. The hook 4b is configured to release the engagement when the drive rod 4a is driven so as to push out the support base 2 (see FIG. 3).

A pair of support mechanisms 5 consisting of air cylinders
The a and 5b are provided on both ends of the rail body 1. That is, the drive rod 6 of the support mechanism 5a, 5b
The tip portions of a and 6b are rotatably provided at the lower portions on both ends of the rail body 1, and the lower portions of the support mechanisms 5a and 5b are rotatably provided on the gantry frame F, respectively. ..

Next, the operation of the apparatus of this embodiment will be described. First, in the horizontal state of the rail body 1 of FIG. 1A, that is, the drive rods 6a of the support mechanisms 5a, 5b,
The work W is placed on the movable table 2 with the 6b retracted.

Next, when the support mechanism 5a is driven and the drive rod 6a thereof is extended as shown in FIG. 1 (b), the rail main body 1 is inclined to the right downward direction. At this time, the air cylinder 4 on the support mechanism 5a side is driven to drive the drive rod 4a.
Is projected, the hook 4b releases the movable table 2 and gives the movable table 2 an initial speed. Therefore, the movable table 2 can smoothly move toward the support mechanism 5b side.

When the movable table 2 moves to the support mechanism 5b side and the movable table 2 is held by the hook 4b (see the chain double-dashed line in FIG. 3), as shown in FIG. 1 (c), the support mechanism 5a. The drive rod 6a moves backward and the rail body 1a is kept horizontal again. Then, the work W is handled by the automatic handling device 10 and carried to a predetermined position.

The vacant moving table 2 is moved to the support mechanism 5a side when the rail main body 1 is opposite to the inclination shown in FIG. 1 (b). That is, the moving mechanism 2 is moved to the supporting mechanism 5a side by driving the supporting mechanism 5b and the air cylinder 4 on the supporting mechanism 5b side. Next, when the drive rod 6b of the support mechanism 5b is retracted, the rail body 1 and the moving base 2 can return to the original state shown in FIG. 1 (a).

As described above, in the apparatus of this embodiment, the work W can be conveyed by inclining the rail body 1 and reciprocating the moving table 2, so that the structure thereof is extremely simple. Further, since the air cylinders 4 provided with the flocks 4b are provided on both ends of the rail body 1, the moving table 2 can be held and the moving table 2 can be given an initial speed.

[0016]

The apparatus of the present invention comprises a rail main body having a length from the movement start point position to the movement end point position of the transported object,
While supporting both ends of the rail body,
A pair of support mechanisms that move each end side up and down,
Since the object to be conveyed is placed in a predetermined posture and has a moving table provided so as to be movable in the longitudinal direction of the rail main body, the structure is simple and the object to be conveyed is kept in a predetermined posture. You can move with.
