BACKGROUND OF THE INVENTION The present invention relates to a pipe cutting method for cutting out pipes that flow while rolling one after another on a line for transporting various pipes, and feeding the pipes to the next process. The present invention relates to an apparatus, and more particularly to a pipe cutting apparatus that can cut out pipes having different diameters.

[0002]

2. Description of the Related Art In a factory that handles various pipes, pipes that flow while rolling one after another using an inclined surface may be taken out one by one and supplied to the next line. Normally, tubes with the same diameter are flowed, but rarely, tubes with different diameters flow randomly depending on the line configuration. In such a case, it is conceivable that the diameter of the pipes flowing on the inclined surface is detected by a sensor, and a cutting tool corresponding to the diameter of the pipes is operated and cut out one by one.

[0003]

However, if the diameter of the pipe body flowing one after another is detected by a sensor, a trouble due to a sensor mistake may occur, and the structure becomes complicated when several kinds of cutting tools are provided.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a tube cutting device which can cut a tube having a different diameter with a simple structure without using a sensor.

[0005]

In order to achieve the above object, the present invention forms a recess having a predetermined size into which a pipe flowing into the upper surface of the tip of a slightly inclined guide member is dropped.
A rotating body notched in a shape to receive a tube is rotatably supported on both side surfaces of the guide member where the concave portion is located , and a further recess is provided at a bottom edge of the notched portion of the rotating body. Depression
The support points for supporting the pipes of different diameters at two points are provided by projections, and the recesses as viewed from the pipe receiving side of the cutouts are formed.
The rear surface, which is the bottom edge located on the deeper side, is cut out and formed so as to be a rear surface on which a pipe having a maximum diameter can be mounted, and has a driving means for rotating the rotating body. .

[0006]

According to the tubular body cutting device of the present invention, the tubular body rolling on the inclined surface of the guide material falls into the concave portion formed on the upper surface of the tip of the guide material, and both ends thereof are received by the notched portions of the rotating body. It is. At this time, the tubular body is supported by two support points protruding from the bottom edge of the notch of the rotating body. By supporting the tube at two points in this manner, the tube can be supported regardless of the diameter of the tube. When the tubular body is received by the rotating body as described above, the rotating body is rotated in the cutting direction by the driving means, whereby one tubular body is cut out.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show a pipe cutting device provided on a line for transporting various pipes. In the figure, reference numeral 1 denotes a transport conveyor for transporting the tube A in a laterally fed state, and a guide member 2 which is slightly inclined is provided at the tip of the conveyor A, and the tube A transported by the conveyor 1 is guided by the guide material. Transfer to 2 above. A recess 3 of an appropriate size is formed in the upper surface of the front end of the guide member 2 to drop the pipe A rolling on the inclined surface.

On both side surfaces of the guide member 2 where the concave portion 3 is located, rotating bodies 4 for cutting one by one while supporting both ends of the tube A are rotatably supported by a shaft 5.
The rotating body 4 has a notch 6 cut out so as to receive the tube A, and the bottom edge of the notch 6 further closes the position close to the receiving side of the tube A at the time of cutting. to protrusively the support points 7,8 as the tubular body a can be supported at two points by cutting away recessed into inverted trapezoidal
Can be. The support points 7, 8 in order to support the various pipe A having different diameters are formed at an appropriate distance according to the tube diameter to be handled. The maximum distance between the support points 7 and 8 is a distance at which one of the smallest pipe diameters to be handled can be placed or can be dropped into the depression. Also, the back surface 9 of the notch 6 , that is, the tube A receiving side
Notch located deeper than inverted trapezoidal depression
The bottom edge of 6 is notched so that the circumference of the tube A does not abut when the tube A is placed, and is cut out to such an extent that the largest diameter tube to be handled can be placed. I have.

FIG. 2 shows the positional relationship between the concave portion 3 of the guide member 2 and the rotating body 4. The supporting point 7 is provided on the bottom edge of the concave portion 3 of the guide member 2 and the notch 6 of the rotating member 4. The depressions between 8 are matched with each other. FIG. 3 is a view showing a state in which the tube A rolled on the guide member 2 is supported by the two support points 7 and 8 of the rotating body 4, and the tube A having a relatively small diameter.
Are supported at two points in a state of deeply entering the recess between the support points 7 and 8 of the notch 6, and the pipe A having a large diameter is supported at two points while slightly fitting into the recess. A large-diameter pipe is less likely to fit into the depression and tries to roll forward, but stops after contacting the back surface 9 of the notch 6 of the rotating body 4.

A lever 11 is attached to the rotating body 4 via a cam clutch 10, and one end of the lever 11 is connected to a tip end of a piston rod 13 of a cylinder 12, and the rotating body 4 is cut out by expansion and contraction of the piston rod 13. It rotates in the direction. The mechanism for rotating the rotating body 4 is not limited to the cylinder 12, but may be any of various rotating methods such as a motor, a pinion rack method, or the like, provided that the rotating body 4 can be rotated in the cutting direction and stopped at a predetermined position. Can be adopted.

FIG. 4 shows another embodiment of the structure of the rotating body 4 in which the notches 6 are provided at four positions of the rotating body 4 by being shifted by 90 degrees. The tube is cut out while rotating by 90 degrees. As described above, the number of cutout portions of the rotating body 4 is not limited to one, and may be appropriately selected according to various conditions of the apparatus.

The tubes A of various diameters conveyed by the conveyor 1 are aligned while rolling on the guide member 2, and the leading tube A falls into the concave portion 3 of the guide member 2, and the rotating member 4 Is received at the notch 6. When the pipe A is received by the rotating body 4 and supported at two points by the support points 7 and 8, the piston rod 13 of the cylinder 12 is extended. At this time, only the cam clutch 10 idles and the rotating body 4 does not rotate. When the piston rod 13 is contracted again, the cam clutch 10 meshes with the rotating body 4 and the lever 1
The rotator 4 is rotated by the angle of 1. The rotating body 4 as shown in FIG.
When the rotating body 4 rotates, one pipe A is lifted and sent to the front part. Then, while the rotating body 4 is rotating, the next aligned pipe body A is stopped in a state where it is prevented from advancing by contacting the circumferential surface of the rotating body 4, and the rotating body 4 is stopped. When the notch 6 of 4 returns to the position of the recess 3 of the guide member 2, the next tubular body A enters the notch 6. Then, by repeating the same operation as described above, the tubes are cut out one by one into the next step.

[0014]

As described above, according to the pipe cutting device according to the present invention, pipes having different diameters can be cut out one by one by the rotating body 4 having a simple structure. The production cost is lower than that of the apparatus utilizing the above-mentioned method, and there are few troubles.
