Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly concerned with the use of one of the shape steels in such a way that when bundling, transporting or loading miso shaped steel and lip groove shaped steel (also referred to as C shaped steel), etc. The present invention relates to an improvement of a device for reversing a steel section, etc. and combining it with another section steel, etc.

Conventionally, for example, miso shaped steel 1 (hereinafter referred to as "shaped steel") produced in a factory is combined so that seven lunges 2 are different from each other, as shown in Figure 1, to reduce the volume and make the shape almost rectangular. Usually, the shaped steel 1 of a product that has been kicked out after passing through a forming machine or cutting machine, or transported on a roller table, has its flange 2 facing upward. It has a rectangular shape and is placed side by side on a skid, etc. Therefore, in order to combine it into the rectangular shape, one of the two section steels 1 must be reversed 1800 degrees and assembled on the other section steel. There is.

Manually reversing and assembling the sections requires a lot of effort and time, and is also dangerous. Many reversing combination devices have been devised or put into practical use, such as dropping and reversing, or inserting a section steel into a notch provided on the outer periphery of the rotor and inverting the section steel by 180° rotation of the rotor. All of them have drawbacks such as complicated structures, resulting in high equipment costs, and the generation of a large amount of noise when reversing and assembling the sections.

In order to solve the above-mentioned drawbacks of the conventional art, the present invention has been developed by simply raising and lowering a combination pedestal having a specially shaped recess in the upper part from below two shaped steels lined up on a table such as a skid. The present invention provides a device that enables the reversal combination of shaped steel, and will be described below based on drawings showing embodiments.

FIG. 2 is a front view, and FIG. 3 is a plan view. After being kicked out from a forming machine or a roller table (not shown), a large number of shaped steel sections 1 are arranged on an inclined skid 3 with the flanges 2 facing upward. They are moved two by two over the stopper 4 onto the horizontal skid 6 by the stopper 5, and are stopped at a fixed position by the stopper 7.

Two or more places in the longitudinal direction of the two shaped steels 1 stopped at the fixed positions, that is, at least two places near both ends, and if the shaped steel 1 is long, one or more places in the middle part are also included. At the bottom of the position, a cylinder or piston type cylinder or piston operated by a fluid pressure such as pneumatic pressure or oil pressure is used so that a combination pedestal 8 having a special shaped recess 9 formed in the upper part thereof, which will be described later, is retracted onto the horizontal skid 6. By the lifting device 21,
It is set up so that it can be raised and lowered in synchronization.

As shown in FIG. 4, the recesses 9 of the pedestal 8 for assembling the front penetrator form a substantially V-shape, each having an inclination angle α with respect to the vertical line.
, β are different from each other, for example, 30' and 45°, and a base 12 perpendicular to the lower end of one hypotenuse 10, and the other end of the base 12 and the other It is formed so as to be connected to the hypotenuse side 11 of , by a vertical line.

Next, to explain the reversal and combination action of the section steel 1 due to the lifting and lowering of the combination pedestal 8, the sequence is as shown in FIGS. When the platform 8 starts to rise from the state where it has descended below the horizontal skid 6, the upper corner of the recess 9 or the hypotenuse io, 1
At i, the two shaped steels 1A and 1B on the horizontal scythode 6 are tilted inwardly to face each other as shown in Fig. The steel flanges 2 intersect, and as the combination pedestal 8 rises, one section steel 1B crosses the other section steel 1 as shown in Fig. 5 (■).
The two sections IA and 1B rotate as shown by the arrows while sliding down so as to come into contact with the inside of the web of A, and then, as shown in Fig. When the assembly pedestal 8 enters the gap and is supported by its bottom side 12 and starts to descend from this state, the shaped steel sections IA and 1B supported by the horizontal skid 6 begin to fall down, as shown in FIG. Finally, as shown in FIG. Alternatively, the material is transferred to another location using a pusher or the like and processed, and the steps shown in FIG.

Note that the shape of the recess 9 of the combination pedestal 8 is not limited to the illustrated example; for example, the diagonal angle α may be larger than the inclination angle β, or it may be modified depending on the shape and size of the target steel section, etc. The shape of the recess 9 can be changed as appropriate, or it can be provided in an adjustable manner.

In other words, FIG. 6 shows the protruding pieces 13 and 14 on the combination pedestal 8
are pivoted by a pin 15 or the like so that a part of the protruding pieces 13, 14 protrudes from the hypotenuse side 10.11, and a locking piece 16 is provided below each protruding piece 13, 14 to receive the combination. A small shaped steel m shown by a chain line is fixed to the table 8 by welding etc.
Even in the case of A and 1B, the reversal assembly work is possible, and in this case the protruding pieces 13 and 14 are locked by the locking piece 16 when the assembly pedestal 8 is raised, and the shaped steel 1A
, 1B are reversely assembled, and when the assembly pedestal 8 is lowered, it freely rotates upward and does not interfere with the shaped steel.

In addition, the combination pedestal 8 shown in FIG.
and adjustment jigs 17, 18 . along the bottom side 12, respectively.
19 is removably attached with a mounting bolt 20 or the like, and one side of each adjustment jig 17, 18, 19 is connected to the hypotenuse 10, 11 of the
And it is made to protrude from the bottom side 12 so that the angle and shape of the diagonal can be adjusted.

In the illustrated row, a large number of screw holes (not shown) are provided in the combination pedestal 8 so that the mounting position of each adjustment jig 17, 18, 19 can be changed, but other combination pedestals 81
/c Dovetail grooves can be provided so that the mounting bolts can be moved along the dovetail grooves, or elongated holes for the mounting bolts can be provided in adjustment jigs 17, 18, and 19 to make the mounting position variable. .

Furthermore, the portion connecting from the lower side of the hypotenuse side 11 to the bottom side 12 is not limited to the vertical line shown in FIG. 4, but may be formed in an arcuate shape as shown in FIG. The steel IB may be smoothly reversed along the curve.

Alternatively, the portions of the combination pedestal 8 where the shaped steels IA and 1B contact or slide are fitted with an elastic material such as rubber or synthetic resin, or a side abrasion material, etc. to prevent noise and wear. Furthermore, the elevating device 21 is not limited to fluid pressure operation, and may be provided to be raised and lowered by, for example, a known electric motor-driven screw type or crank type.

In addition, the sections IA and 1B to be assembled are placed not only on the horizontal skid 6, but also on a stationary table or a roller table with stopped rollers, and the above-mentioned device is installed between the tables for inversion and combination work. You may also do this.

The present invention is constructed as described above, and has an extremely simple structure, which reduces equipment costs.Furthermore, the work of reversing and assembling shaped steel can be done quickly and easily simply by raising and lowering the assembling pedestal. As shown in FIG. 5, the movement of the shaped steel etc. is rotated while being supported by the assembly pedestal, which has the effect of suppressing noise generation as much as possible.

Note that the present invention is not limited to the miso shaped steel in the above embodiments, but can also be applied to other similar shaped products.
