DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a section steel feeding apparatus for feeding a section steel having a vertical plate and a horizontal plate such as an H-section steel or a channel steel to a processing machine, and a section steel using the apparatus. It is related to the material sending method.

[0002]

2. Description of the Related Art Referring to FIGS. 10 and 11, a carriage type feeding device 103 for feeding an H-shaped steel W to a conventional H-shaped steel drilling machine 101, for example, as an H-shaped steel drilling machine, is shown in FIG. In order to send the tail end of the section steel W to the drill 105 position,
The main body vise 107 as the first clamping means provided on the near side of the drill 105 (the right side in FIG. 10A) is avoided, and the material feeding clamper 10 as the second clamping means is avoided.
9 needs to be clamped. The drill 105
On the other side (left side in FIG. 10A), a front vise 111 for fixing the shaped steel W at the time of processing is provided.

As a method of avoiding the main body vise 107 and clamping it, as shown in FIG. 10B, a notch 113 is provided at a lower portion of the main body vise 107, and There is one in which the clamper 109 is inserted to clamp the tail end of the H-section steel W (see Japanese Utility Model Application Laid-Open No.

2. The material feeding device for a shaped steel according to claim 1, wherein the second clamping means includes a web clamping claw for clamping a web of the shaped steel, and a flange clamping claw for clamping a flange of the shaped steel. It is characterized by comprising.

Therefore, for example, when the material is fed by clamping the tail end of the flange with the flange clamping pawl and the second clamping means interferes with the first clamping means, the web is again grasped by the web clamping pawl and further clamped. Send the material.

According to a third aspect of the present invention, there is provided a method for feeding a shaped steel having a vertical plate and a horizontal plate to a shaped steel working machine in order to perform processing by clamping the shaped steel having a vertical plate and a horizontal plate. In the steel feeding method, the tail end of the vertical plate or the horizontal plate is clamped by a second clamp means to feed the steel, and when the second clamp means approaches a position where it interferes with the first clamp means, the first clamp means is provided. And the second clamping means is unclamped, and the second clamping means is pivoted to re-clamp the horizontal plate or the horizontal plate at a position where it does not interfere with the first clamping means. It is characterized by unclamping and feeding the material.

Therefore, when the tail end of the vertical or horizontal plate of the section steel is clamped by the second clamping means and the second clamping means is moved to feed the section steel to the section steel processing machine, the second clamping means is used.
When the clamp means approaches the position where it interferes with the first clamp means, the section steel is once clamped by the first clamp means and the second clamp means is unclamped, and then the clamper is turned so as not to interfere with the first clamp means. Refeed the horizontal or vertical plate before feeding.

As described above, in the section steel feeding apparatus according to the first aspect of the present invention, the tail end of the section steel is clamped by the second clamping means, and the carriage is moved to form the section steel. When the second clamp means interferes with the first clamp means when feeding the material to the machine, the turning mechanism rotates the second clamp means to re-grasp it to a position where it does not interfere with the first clamp means, and then feeds the material. Is performed, the shaped steel can be fed to a position where the second clamp means exceeds the position of the first clamp means.

In the material feeding apparatus for section steel according to the second aspect of the present invention, the material is fed by clamping the tail end of the flange with, for example, a flange clamping claw, and the second clamp means interferes with the first clamp means. Since the web is again gripped by the web clamping claws and the material is further fed, the shaped steel can be fed beyond the position of the first clamp means without the second clamp means interfering with the first clamp means.

In the method for feeding a shaped steel according to the third aspect of the present invention,
When the tail end of the vertical or horizontal plate of the shaped steel is clamped by the second clamping means, and the second clamping means is moved to feed the shaped steel to the shaped steel processing machine, the second clamping means sets the first When approaching the position where it interferes with the clamp means, the section steel is once clamped by the first clamp means and the second clamp means is unclamped, and then the second clamp means is turned to move the steel section to a position where it does not interfere with the first clamp means. Since the feeding is performed after the plate or the vertical plate is grasped again, the shaped steel can be fed to a position where the second clamp means exceeds the position of the first clamp means.
