Abstract

PURPOSE:To invert a horizontal member without use a manpower by moving the horizontal member conveyed by a conveying chain until it strikes upon a stopper, and by stopping a motor while turning a raising plate so as to invert the horizontal member when it strikes upon the stopper. CONSTITUTION:A conveying chain 3 is driven by operating a motor 4 so as to drive a first cylinder 8 in order to set a raising plate 5 in parallel with the conveying chain 3, and to drive a second cylinder 10 so as to project a stopper 12 from the raising plate 5. A horizontal member 18 is set and conveyed on a conveying chain 3 until it strikes upon the stopper 12, and as a result, a limit switch or the like is operated so as to stop the motor 4. Accordingly, the horizontal member 18 is held being laid on the raising plate 5. Then, a third cylinder 16 is driven to stand up a support plate substantially perpendicular to the conveying chain 3, and in this condition, when the first cylinder 8 is driven to be stood up, perpendicular to the conveying chain 3 and the rising plate 5, the horizontal member 18 is turned by an angle of 90deg. and is then settled on the conveying chain 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material raising device for reversing a horizontal member for inspecting the horizontal member.

[0002]

2. Description of the Related Art Conventionally, in order to inspect a machined surface of a long horizontal material such as a horizontal material, the horizontal material sent to the table must be manually laid down or turned upside down. I was doing.

[0003]

By the way, such a work of manually laying down or overturning such a long, wide and thick horizontal member is a very powerful work, and it takes two people. There was a problem that it would go down after 4 or 5 work.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a transport chain for transporting a long cross member orthogonally to its longitudinal direction, a transport chain parallel to the transport chain, and one end fixed to a rotary shaft. A raising plate, a first cylinder connected to a rotating shaft for rotating the raising plate, a stopper orthogonal to the raising plate and protruding from the raising plate, and the raising plate. Mounted on the second cylinder for projecting and returning the stopper, a supporting plate whose one end is rotatably fixed to a rotating shaft near the raising plate, and the supporting plate is rotated. In order to achieve this, a third cylinder in which a drive shaft is connected to the rotating shaft is provided.

[0005]

According to the present invention, the first cylinder is driven to bring the raising plate in a state parallel to the conveying chain, the second cylinder is driven to raise the stopper to project from the plate, and the conveying chain is driven by the motor. When the horizontal material is driven and placed on the conveyor chain and conveyed, and moved until it abuts on the stopper,
Stop the motor with the limit switch installed on the stopper.

Then, the third cylinder is driven so that the supporting plate is erected at a right angle to the conveying chain, and in that state, the first supporting plate is placed.
When the cylinder is driven to raise the raising plate at a right angle to the conveyor chain, the horizontal member is mounted on the conveyor chain by rotating 90 degrees, so it is possible to inspect the conveyor chain side of the horizontal member. it can.

1 is a plan view of a material raising apparatus according to an embodiment of the present invention, FIG. 2 is a side view of the material raising apparatus of FIG. 1, and FIG. 3 is a front view of the material raising apparatus of FIG. A transport chain support 2 is mounted on the top of the transport chain 1, and a transport chain 3 is mounted on the transport chain support 2.
Is driven by a motor 4 via a gear or the like, and only a part of the device is shown in this figure.

Two raising plates 5 each having one end fixed to the rotary shaft 6 are mounted in parallel with the transport chain 3, and a first arm 8 is driven by a rotary arm 7 fixed to the rotary shaft 6. The shaft 8a is connected, and further, the first cylinder 8 is connected to the base 1
Is supported by a support member 9.

Further, the second cylinder 10 and the guide 11 are fixed to the raising plate 5, and the stopper 1 is passed through the guide 11.
2 is mounted, and the stopper 12 has a hole 5a in the raising plate 5.
One end of the stopper 12 is protruded from the other end, and the other end of the stopper 12 is connected to the drive shaft 10a of the second cylinder 10.

A rotary shaft 13 is mounted parallel to the rotary shaft 6, and one end of a support plate 14 is mounted on the rotary shaft 13.
Further, a rotary arm 15 is fixed to the rotary shaft 13, and the rotary arm 1
5, the drive shaft 16a of the third cylinder 16 is connected, and further, the third cylinder 16 is supported by the support member 17 to form the base 1.
Supported by.

In the material raising apparatus of this embodiment having the above-described structure, the motor 4 is driven to drive the conveying chain 3, and the first cylinder 8 is driven to make the raising plate 5 parallel to the conveying chain 3. It is provided and the second cylinder 10 is driven to raise the stopper 12 so that the stopper 12 is projected from the plate.

Then, when the horizontal member 18 is placed on the conveyor chain 3, the horizontal member 18 is sent by the conveyor chain 3 and is moved until it hits the stopper 12. (Not shown) operates to stop the motor 4, so that the horizontal member 18 is placed on the raising plate 5.

Therefore, when the third cylinder 16 is driven to project the supporting plate 14 so as to be substantially perpendicular to the transport chain 3 and the first cylinder 8 is driven, the horizontal member 18
Is inverted 90 degrees and placed on the conveyor chain 3, but the support plate 14 is provided so as not to further overturn when the horizontal member 18 is inverted.

In this way, by inverting the horizontal member 18 by 90 degrees, the entire surface can be inspected, and there is an advantage that no human is required to invert the horizontal member 18.

Although the first and third cylinders 8 and 16 are used in the above-mentioned embodiment, a chain may be connected to the rotating arms 7 and 15 and the chain may be wound by a motor. It can be carried out.

[0016]

As described above, the material raising device of the present invention moves the horizontal member conveyed by the conveying chain until it hits the stopper, and when it hits the stopper, stops the motor and then raises it. Since the plate is rotated to invert the horizontal member, the horizontal member can be inverted without manual labor, and thus there is an advantage that no labor is required and the work becomes very smooth.
