Description

[Detailed Description of the Invention] The present invention relates to a reversing machine equipped with one reversing lever.

Surface inspection, scratch removal, scuffing, etc. of square ingots, square shaped materials, H-shaped materials, etc. are usually performed by inverting the materials using a reversing machine.

However, as shown in FIGS. 1 to 3 of the accompanying drawings, the conventional reversing machine combines a pair of reversing levers 1.1' with one end thereof rotatably assembled by a pin 2, and each reversing lever 1. 1' are respectively attached with cylinders 3 and 3', and are further provided with a shifter device 4 for returning the inverted material to its original position.

When a conventional reversing machine having such a configuration is used, first, as shown in FIG. 1, the material 5 is placed on the reversing lever 1, and as shown in FIG. By the operation of the cylinders 3 and 3', the reversing levers 1 and 1' are made into a ■-shape, and the material 5 is transferred onto the reversing lever 1', and then,
As shown in FIG. 3, when both reversing levers 1.1' are set horizontally, the material 5 is reversed by 90°.

Furthermore, when the material 5 is to be reversed, the material is moved in the direction indicated by the arrow X by operating the shift device 4, as shown in FIG.
Push it in the direction shown and slide it over the reversing lever 1.
It is sufficient to return the material 5 to its original position and then repeat the same operation.However, the reversing machine having such a configuration and operation has the following drawbacks.

That is, (1) the cylinder of the shifter device 4 is strong, and
(2) The reversing machine requires a large motor, unit, etc. (3) Therefore, the overall installation area becomes large (4)
For example, the cycle time for reversing and returning to the normal position becomes longer.

Therefore, the present invention eliminates the various drawbacks of the conventional ones as described above and provides a one-stop system without using a shifter device.
The object of the present invention is to provide a reversing machine capable of easily reversing materials using only a book reversing lever.

Hereinafter, the present invention will be described with reference to figures 4 to 8 of the attached drawings showing one embodiment thereof.
This will be explained based on the diagram.

As shown in FIG. 4, the reversing machine according to the present invention has a frame 11 having an inclined surface 10 on its upper surface, and a reversing lever 12 near the lower end of the inclined surface 10 and a pin 1 at one end thereof.
3, and is rotatably attached via the reversing lever 12.
and a frame 11 are connected by a cylinder 14.

Incidentally, the inclined surface 10 may be attached to the frame 11 either in a fixed manner or in a movable manner (fixed when in use), and the inclined surface 10 may be attached to the frame 11 in a fixed manner or in a movable manner (fixed when in use). The angle α shall be larger than the friction angle so that the material will slide down under its own weight.

Further, the reversing lever 12 is the same as the conventional lever, but the cylinder 14 has a slightly longer stroke than the conventional lever.

Further, a stopper 15 is formed on the frame 11 so as to be opposed to the end of the reversing lever 12, but instead of this, as shown in FIG.
Alternatively, a stopper 12' may be provided.

The present invention has the above configuration, and its operation will be explained next.

As shown in FIG.
4, the material 5 is rotated around the pin 13 and transferred onto the inclined surface 10 (FIG. 6).

Next, by the action of the cylinder 4, the reversing lever 12 is turned in the opposite direction until it is aligned with the inclined surface 10, and the material 5 is slid down so as to hit the stopper 15 (FIG. 7).

Next, when the reversing lever 12 is turned upward again, the inclination angle becomes less than the friction angle, so the material 5 no longer slips (
Figure 8).

In this state, the reversing lever 12 is returned to the initial state shown in FIG.

One cycle is completed by the above process.

As described above, the present invention has an extremely simple structure and is easy to operate.1.In particular, it does not require a shifter device, so the cycle time can be extremely shortened.2.The capacity of the prime mover, unit, etc. It can be small and the weight of the frame can be reduced. 3. It has excellent effects such as a small installation area.
