Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for shaping round steel such as steel bars and steel pipes so that they can be easily bundled with wire or the like.

These round bars need to be bundled for storage and transportation, but the conventional method of bundling is to hang them using an overhead crane, adjust the shape, and then bind them with wire. There are disadvantages such as monopolizing the crane for a long period of time, hindering its effective use, creating a risk of the wire rope becoming dislodged or being cut, and causing shock and noise due to the round steel falling off.

The present invention aims to provide a round steel bundling device that does not use an overhead crane and eliminates these drawbacks.
A skid that conveys round steel in parallel, a kicker device that flips the round steel upward one by one, an upper skid that supports the round steel thrown up by the kicker device in parallel, and a skid that partially overlaps with the upper skid. The front part descends a little and bridges the upper part of the shaping groove, and the round steel thrown up by the kicker rolls on the upper surface and comes into contact with the stopper on the upper part of the shaping groove in front and stops. The round bars are stopped in parallel until a predetermined number is reached, and when the predetermined number is reached, the hydraulic cylinder is activated and tilts around the pivot, ejecting all the round bars on the top surface into the shaping groove, and the protrusion at the rear end rises. The turning arm prevents the following round steel from continuing, and the round steel is U-shaped in the longitudinal direction, with the upper end of the stopper side wall surface being approximately 45° and the upper end of the kicker side being approximately 60°.
(It slopes inward to form a guide surface, and the bottom surface moves forward by 5 degrees to 12 degrees.)
° Consists of the shaping groove that receives and shapes the round steel discharged by the turning arm that is inclined and forms a shaping surface, and a belt such as a chain that surrounds the shaping groove from below and has both ends fixed to the upper part of both side walls of the groove. This shaping device for bundling round steel is characterized by comprising a shaping band that surrounds and shapes the round steel by picking up a guide ring at the tip of the curved handle from below with a fluid pressure cylinder.

The present invention will be explained in detail based on embodiments shown in the drawings.

Embodiments FIGS. 1 to 4 are side views of the apparatus of the present invention arranged in the operating order in the operating state.

Figure 1 shows the state in which round bars 1 to be bundled roll horizontally in parallel on skids 2 and are conveyed to the device of the present invention. In this example, seven round bars 1 are An example of bundling as one bundle is shown, and for the convenience of explaining the shaping state, the arriving round bars 1 are sequentially bundled.
They shall be numbered 口, ha, second, ho, heto.

Figure 2 shows the state in which a set of round steel A, 口, HA, 2, HO, HE, and G have been lifted one by one to the upper stage using the kicker 3, which is the lifting device. A skid upper stage 12 is formed continuously on the skid 2 via a slope, and a third skid upper stage 12 is formed continuously through a slope.
As clearly shown in the figure, the rotating arm 4, which is pivoted on a pivot 6 and rotated by a hydraulic cylinder 10, is supported with its upper surface overlapped with the skid upper stage 12 and its front part lowered slightly. 1 rolls forward and laterally on the skid 12 and the rotating arm 4, and comes into contact with the stopper 11 and stops.

The remaining round steel holes, C, 2, H, H, and G, follow round A, moving forward in the horizontal direction, adhering to each other, and stopping in parallel.

When all the round bars A, 口, H, 2, H, H, and G are stopped in parallel, the font pressure cylinder 10 is activated by an electric signal from a counting device (not shown) that is linked to the number of kicks of the kicker 3. As the piston is contracted, the rotating arm 4 rotates downward about the pivot 6 and discharges all of the round steels A, 0, C, 2, E, H, and G supported on the upper surface into the U-shaped shaping groove 5. .

The method of detecting the number of bounces of the round steel and operating the hydraulic cylinder 10 is not limited to the method described above, but may be any other electrical or mechanical method.

At this time, the protrusion 7 at the rear end of the rotating arm 4 is raised high above the upper surface of the skid 12, so that the following round bar 1 is replaced by the preceding round bar 1.
Prevent the mixture from entering the group.

The round steel 1 discharged forward from the upper surface of the rotating arm 4 is shaped into a shaping groove 5.
It is deposited in bales at the bottom of the tank.

There is a meaning in stacking bales at the bottom of this U-shaped shaping groove 5.

That is, if this bale stacking is carried out as specified, it will be possible to easily shape the bales into a well-ordered flower shape with a circular cross section as shown in FIG. 4 without applying unnecessary force.

However, the most difficult part in the present invention was the shape of the U-shaped shaping groove 5, and simply the turning arm 4 that holds the round steel and the U-shaped shaping groove 5.
It is not easy to create such a stacked shape by simply combining the character shaping grooves 5, and after many trials of thought and error, we found the appropriate shape for the shaping grooves.

Figure 3 shows the round steel ejected forward from the upper surface of the rotating arm 4.
This shows the state in which the kuchi, ha, ni, ho, he, and to are shaped and deposited in a bale shape at the bottom of the shaping groove 5, and FIGS. 5 to 10 illustrate this process.

In order to make steel pipes lined up in parallel as shown in Fig. 5 into a stacked shape as shown in Fig. 10, the shape of the U-shaped shaping groove in the part where the steel pipes come into contact is important, and the degree of rotation of the turning arm 4 is important. There is also the issue of whether the angle of inclination or the turning speed is sufficient.

However, if the shape of the shaping groove is determined, the inclination angle of the rotating arm will be
It can be easily designed as appropriate.

Further, the side wall surface of the stopper is provided at a position along the upper end of the front wall surface so that the round steel can easily fall into the shaping groove.

As a result of such studies, the shaping groove 5 following the stopper 11
The upper end of the front wall surface of the groove 5 is inclined inwardly by about 45°, the upper end of the rear wall surface of the groove 5 is inclined inwardly by about 600°, and the bottom surface of the groove 5 is inclined forwardly by about 100°. Given the.

Next, the procedure for stacking bales will be explained with reference to FIGS. 5 to 10.

FIG. 5 shows a state in which the rotating arm 4 has not yet started rotating and the round bars A, 口, HA, 2, HO, HE, and TH are supported horizontally and in parallel on the upper surface.

FIG. 6 shows a state in which the turning arm 4 is slightly turned, the discharge of the first round steel A is delayed, and the second round steel opening is lined up and lowered first.

Figure 7 shows the state in which the rotating arm 4 has further rotated and descended, the first round bar A has fallen into the upper recesses of the second and third openings, and the fourth round bar 2 has been pushed up.

Figure 8 shows that the rotating arm 4 further rotates and descends, and finally the 4th and 2nd
It shows the state where it has fallen into the upper recess of No. 8 and No. 5.

FIG. 9 shows a state in which the rotating arm 4 is further rotated and lowered, the fourth arm 2 is supported on the first arm A and the fifth arm E, and the arm 2 has moved upward to the sixth arm.

FIG. 10 shows the state shown in FIG. 3, in which the turning arm 4 has completely turned and retreated, and the round bar 1 is in the bottom wall soil at the second opening, third inspection C.
The 5th E and 6th rows are parallel to each other, and the 1st A, 4th 2nd, and 7th G are parallel to each other, and the 1st A, 4th 2nd, and 7th G are parallel to each other, and the whole is shaped like a bale stack. Show the status.

There is a delicate relationship between the slope angle of the bottom surface of the shaping groove 5 when the round steel 1 is shaped into a bale type, and when the turning speed of the turning arm 4 is set to 5 to 10 seconds per turn, there is almost no impact noise. No, the angle is 5
It has been experimentally shown that ˜12° gives the best shaping.

Figure 4 shows round steel I shaped into a bale shape in the shaping groove 5.
The mouth, ha, two, ho, he, and to are further shaped into a flower shape with a circular cross section and tied in this state, surrounding the shaping groove 5 from below and attaching both ends to the upper part of both side walls of the groove. Fulcrum 13.14
The guide ring 16 at the tip of the curved handle 15 is lifted from below with the tip of the piston rod of the fluid pressure cylinder 9, and the round steel 2 is used as a rose. It is characterized in that it is shaped into a circular flower-shaped cross section with petals, and in this state it is tied with wire.

If the present invention is carried out, an overhead crane is not used and the wire is not suspended, so there is no risk of the wire coming off or being cut, and there is an effect that there is almost no impact noise.

In addition, the device of the present invention allows round steel to be piled up in bales easily in the shaping groove, and then shaped into a flower shape with an orderly circular cross section, so there is no need for any unnecessary force for binding, and the device can be made lighter and smaller. It is possible.
