Description

[Detailed Description of the Invention] The present invention relates to a device for loading and unloading pipes and the like onto turning rollers.

Cutting and welding of pipes is usually carried out by placing the pipe on a turning roller and rotating it.In order to perform assembly line work smoothly, a loading stage is placed in front of the turning roller a, as shown in Figure 1. In addition, a carry-out stand C is installed at the rear of the pipe, and a tube holder d is installed between the carry-in stand and the carry-out stand C so that it can be raised and lowered by a cylinder e.

Conventionally, in order to guide the pipe f onto the turning roller a, the tube was manually rolled on a loading table, the receiver was stopped at the center of the table d, and then the cylinder e was lowered.

Moreover, when sending out the tube f after force handling, the receiving platform d was raised from the cylinder 6vc and pushed and rolled toward the unloading platform C side.

In addition, instead of manually stopping and feeding the tube as described above, some devices are provided with a stopper that can be moved up and down and a cylinder that feeds out the tube in a horizontal direction.

However, in the former case, the work efficiency is poor because the control is performed manually, and in the latter case, the structure is complicated and expensive.

The present invention was proposed in view of the above-mentioned points, and includes a working turning roller and a liftable pipe holder for placing the pipe, etc. on the turning roller between the loading stage and unloading stage for pipes, etc. For carrying equipment such as pipes equipped with a stand, the pipe holder is equipped with an inverted dogleg-shaped lever whose upper end is bent in the insertion direction and whose lower end is equipped with a balance weight. A pair of stoppers are attached to the tube holder at intervals along the tube receiving direction, and maintain the lever in the upward position when receiving the tube, and maintain the lever in the downward position when carrying out the tube. The purpose is to provide a device for carrying in pipes, etc., which has a simple structure and can carry in and out pipes, etc. reliably and quickly. be.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

1 is a pair of turning rollers; 2 is a tube loading table; 3 is a tube loading table; 4 is a tube support for placing the tube on the turning roller 2; 3
It is designed to be raised and lowered at approximately the same height as 1.

Reference numeral 6 denotes an inverted dogleg-shaped lever having an upper end bent in the insertion direction and a balance weight 7 at the lower end.

Receptacles 9 and 10 are provided on the stand 4, and allow the rotation range of the lever 6 to be within a predetermined range around a vertical line. the lever 6 when the tube holder 4 rises to carry out the tube 1.
It is a pair of stoppers that regulates the downward direction.

In the above configuration, in order to place the tube on the turning roller 1, the cylinder 5 first raises the support platform 4 to the position shown in FIG.

At this time, the lever 6 is at the experiment position shown in the figure due to the action of the balance weight 70. The pipe is fed from the loading table 2, the lever 6 is rotated to the position shown by the two-dot chain line in the figure, and the receiver is placed at a predetermined position on the table 4. will be placed on.

In this state, when the receiver 4 is lowered by the cylinder 5, the pipe is placed on the turning roller 1, resulting in the state shown in FIG.

On the other hand, when sending out the tube after processing, the cylinder 5 is raised and the lever 6 is regulated by the stopper 9vc, so the back of the lever 6 is against the tube fc and the tube can be sent out to the carrying out table 3 side. .

As is clear from the above embodiments, according to the present invention, pipes and the like can be carried in, carried out, and stopped at predetermined positions reliably and quickly with an extremely simple structure that only includes a lever and a stopper.
