Description

[Detailed Description of the Invention] The present invention relates to a tube loading/unloading device for loading and unloading tube materials onto and from turning rollers.

When cutting or welding a tube, the tube is generally placed on a turning roller and rotated during the work.

Figure 1 shows a conventional pipe loading/unloading device onto a turning roller.
In addition, a stand e is provided between the carry-in stand and the carry-out stand C for the tube to be raised and lowered by the cylinder d, and when feeding the pipe material f onto the turning roller a, the stand e is raised. , the pipe f is manually rolled and the receiver stops at the center on the stand e, and then the receiver lowers the stand e and places it on the turning roller a.
When sending out from above, the receiver raises platform e and then moves to unloading platform C.
Pushing it to the side.

In addition, instead of manually carrying in, stopping, and taking out the tube as described above, there is a device that is provided with a stopper that can be moved up and down and a cylinder that carries out the tube in a horizontal direction.

However, in the former case, the work efficiency is poor because the pipe materials are brought in, stopped, and taken out as they are obtained, and in the latter case, the structure is complicated and expensive.

The present invention was proposed in view of the above-mentioned points, and is a device for carrying in and out of a pipe onto a pair of turning rollers provided between a pipe carry-in table and a pipe carry-out table. The crankshaft has a free end rotatably connected to a crank pin portion of the crankshaft installed adjacent to the sides of the pair of turning rollers, and its base end is located below the loading table in the direction of pipe delivery. A connecting rod is flexibly connected to a piston rod of a crankshaft drive cylinder which is arranged diagonally upward facing the direction of the cylinder, and a connecting rod is fixed to the free end of the connecting rod, and when the piston rod is fully extended, A tube receiving surface for receiving a tube is provided on the upper surface, and when the piston rod is retracted, the tube is lowered from the upper surface of the turning roller and the tube on the tube receiving surface is placed on the turning roller, and when the piston rod is re-extended, the turning roller It is characterized by comprising a loading pile member having a tube delivery surface on the front surface that scoops up the tube on the roller and pushes it out to the loading platform, and its purpose is to reliably and quickly carry in, stop, and unload the tube material. It is an object of the present invention to provide a pipe loading/unloading device which is simple in construction and inexpensive.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

1 is a pair of turning rollers, 2 is a tube loading table, 3 is a tube loading table, 4 is a crankshaft rotatably installed between the loading table 2 and the loading table 3, and 5 is a crank pin portion of the crankshaft 4. 4a is a tube loading/unloading member rotatably mounted, and the tube holder has a tube receiving surface 5a and a tube feeding surface 5b.

Reference numeral 6 denotes a connecting rod that is integrally fixed to the carry-in pile member 5 by welding or the like, and one end is rotatably connected to the crank pin portion 4a, and the other end is connected to the piston rod 7a of the air or hydraulic cylinder 7. .

In the above configuration, when carrying the pipe material onto the turning roller 1, the piston rod 7a of the cylinder 7 is assumed to be at the most pushed out position, and at this time, the carrying-in mountain member 5 has a pipe holder with the receiving surface 5a as shown in FIG. After the pipe material is placed on the carrying-in pile member 5 in this state, when the cylinder 7 is actuated to retract the piston rod 7a, the carrying-in pile member 5 is placed in the fourth position. As shown in FIG. 5, the turning roller 1 rotates together with the crankshaft 4.
The tube is moved downward and placed on the turning roller 1.

When the pipe material processing work is finished and the pipe material is to be sent onto the carrying-out table 3, the cylinder I is operated to push out the piston rod 7a, and the carrying-in pile member 5 changes from the state shown in FIG. 5 to the state shown in FIG. It rotates to the state shown in FIG. 2, lifts the tube material on the turning roller 1 with the tube delivery surface 5b, and sends it out onto the carry-out table 3, returning to the state shown in FIG.

Note that a plurality of the above-mentioned carry-in pile members 5 and cylinders 7 are installed as shown in FIG.
It is advisable to install one of the cylinders so that the termites always rotate clockwise.

As is clear from the above embodiments, according to the present invention, the loading, stopping, and unloading of pipe materials can be carried out reliably and quickly, and the loading pile member that performs this action can be operated by a single system of cylinders. Therefore, the configuration is simple and inexpensive.
