Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shape steel straightening line handling device.

Conventionally, most straightening machines for section steel are single-row type,
I haven't seen many double-row ones.

This is because the caliber roller of a straightening machine is usually supported in a cantilevered manner, and straightening double rows of section steel at the same time with such a cantilevered caliber roller requires a large straightening force, and at the same time, there is damage caused between multiple materials. This is because it was believed that a state of correction would occur.

However, a section steel with a relatively simple cross-sectional shape and small dimensions (
It has been found that double-row straightening is also possible with angle iron, etc.).

The double-row straightening machine is equipped with caliber rollers for straightening the materials sent in double rows to the straightening machine, and the caliber rollers are provided with straightening sections for unit materials at equal pitches.

Therefore, in double-row straightening, it is necessary to arrange the materials before the double-row straightening machine at a pitch that matches the pitch of the straightening parts of the caliber rollers, and then feed the materials into the straightening machine.

For this reason, a pitch alignment device is installed in front of the double-row straightening machine, but even though it is a pitch alignment device, when receiving the shaped steel into this device, the double-row shaped steel is aligned at a nearly constant pitch. It is desirable and necessary that the

Due to this relationship, we adopted a pitch alignment device that receives multiple shaped steel sections in double rows in close contact with each other, rearranges them at the required pitch, and then feeds them into a double row straightening machine. It is operationally advantageous to do so.

The present invention proposes a handling device that can automatically feed a plurality of sections into a pitch aligning device as double rows of sections in close contact with each other while the sections are traveling in a double row in a section steel straightening line. Embodiments thereof will be described below based on the drawings.

Reference numeral 1 denotes a double-row straightening machine, and the shaped steel to be straightened by the double-row straightening machine 1 is rolled to its final size by a rolling mill (not shown), and sent to a cutting machine (shear) 2 as a product.

A shaped steel straightening line L is provided at the top of the double-row straightening machine 1,
In addition, a shaped steel delivery line 1 is provided downstream.

A cooling bed 3 is provided between the shaped steel straightening line L and the cutting machine 2, and the shaped steel cut into long lengths by the cutting machine 2 passes through a roller table 4 on the cooling bed entrance side and is transferred to the cooling bed 3 one by one. sent to.

The moving directions of the section steel on the cooling bed entry side roller table 4 and the cooling bed 3 are set to be orthogonal to each other,
In the cooling bed 3, the section steel is moved in a direction perpendicular to its axis and cooled during its movement.

The cooled steel sections are taken out one by one to a take-out device 5 attached to the cooling bed 3, and are collected into a plurality of sections.

A cooling bed mountain side roller table 6 is provided between the take-out position of the take-out device 5 and the start of the section steel straightening line L so as to be located on the extension line of the straightening line L. The steel sections assembled into books are sequentially transferred to this cooling bed exit roller table 6 by a skid transfer (not shown).
passed on to the top.

The cooling bed outlet roller table 6 is stopped from driving until it picks up the shaped steel, and is activated after the pick is picked up.

In this way, a plurality of shaped steels are fed into the straightening line L in double rows.

The illustrated example shows a case where an angle iron 1 as an example of a shaped steel is handled.

As is clear from FIG. 2, the angle iron 7 moving on the cooling bed exit roller table 6 is in a stable position, that is, with the apex up and the bottom of the belly down, and the angle iron 7 at that time is in a stable position. Steel 7 mutual pitch is at random Pl, P2
7. P3. ..., and the angle irons 7 are not parallel to each other.

The straightening line L consists of a pitch alignment device 8, a section steel line L1 on the front side thereof, and a transfer line L2 between the pitch alignment device 8 and the double-row straightening machine 1. An elevating and retracting type lifting stopper 9 is provided in the line L2.

As described above, the pitch alignment device 8 has the function of receiving a plurality of angle irons T in a double row state in close contact with each other, distributing them to a required pitch, straightening them by one line, and then sending them to the double row straightening machine 1. The reference line after the pitch alignment and the reference line before the pitch alignment are aligned with the reference line of the caliber rollers of the double-row straightening machine 1 in the traveling direction of the angle iron 7.

Therefore, when one side edge of the angle iron group consisting of double row angle irons 7 is aligned with this reference line and fed into the pitch alignment device 8 or the double row straightening machine, the pitch alignment or the straightening of each angle iron 7 can be done easily and easily. It is done accurately.

The carry-in line L1 on the upper side of the pitch alignment device 8 is constituted by a skew roller table (skew roller table 10) over its entire length.

The skew roller table 10 has a side guide 11 having a reference surface S at a position that coincides with the reference line in the direction of movement of the angle iron 7, and a plurality of horizontal conveyance rollers 12.
, the end 12a on the side guide 11 side is the pond end 12
They are inclined so as to be located further forward (downward) in the direction of movement of the angle iron 1 than b, and are provided so as to be parallel to each other.

Each transport roller 12 is connected to an individual drive device 13.

In FIGS. 2 and 4, reference numerals 14 and 15 indicate the roller table 6 on the cooling bed outlet side and rollers 14 and 15 of the transfer line L2, respectively.

As a result, a random pitch P1. P2. P3. The double-row angle iron 7 fed to the skew roller table 10 in ......, because its conveyance roller 12 is inclined as described above,
Due to the action of the rotation component force, while moving on the skew roller table 10, all the angle irons 7 are brought together against the reference surface S of the side guide 11, as shown in FIG. They are arranged at pitch PA.

The angle iron 7 is then subsequently attached to the skew roller table 10.
and is fed into the pitch alignment device 8.

At this time, the lifting stopper 9 protrudes, and the double-row angle irons 7 collide with this lifting stopper 9, so that their tips are aligned.

Thereafter, the pitch of the angle irons 7 is aligned by the pitch alignment device 8 to the pinch PB for correction by the caliber rollers (not shown) of the double-row straightening machine 1, as shown in FIG.

The angle irons 7 are fed into the double-row straightening machine 1 via the transfer line L2 for pitch alignment and support, and after straightening are carried out via the carry-out line e.

At this time, it is assumed that the lifting stopper 9 is retracted.

In this embodiment, the skew roller table 10 is arranged along the entire length of the shaped steel delivery line L1. A part of the shaped steel delivery line L1 may be configured as a skew roller table.

It goes without saying that the side guide 11 may be fixed to the skew roller table 10, or may be configured so that its position can be adjusted in the width direction.

As explained above, according to the present invention, a plurality of shapes are inserted into a pitch aligning device that receives a plurality of shaped steels in a double row state in close contact with each other, rearranges them at a required pitch, and then sends them to a double row straightening machine. The feeding of the steel can be carried out after automatically and accurately handling the steel section while it is being fed.

Since there is no need to provide a special device for this purpose outside the shaped steel straightening line, it can be carried out without making any major modifications to the conventional device.
