DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an H-beam rejection facility, and more particularly, to an H-beam rejection facility.
The present invention relates to an H-section steel rejection facility for rejecting defective products contained in a section steel from a transfer line.

[0002]

2. Description of the Related Art H-section steels are widely used as architectural and structural members, and are usually painted or oiled before being shipped. FIG. 5 is a bird's-eye view showing an example of an H-shaped steel refinement line including a coating machine and an oiling machine. The H-shaped steel 1 cut to a fixed length is oiled while being transported on a transport line at a constant pitch. After being oiled by a machine 31 or dried by a drying furnace 33 after painting by a painting machine 32, the flanges are piled up by a piler 34, and then compactly stocked.
It is suspended at 36 and transported / loaded on a transportation means such as a trailer or a ship (not shown) and shipped. The transport line is configured by transport means such as the roller conveyor 2, the belt conveyor 38, the vertical peg type conveyor 39, and the like.

[0003] In most cases, the H-section steel 1 is conveyed in an I position in which the web width is erected. However, when coating, the flange bottom surface must be removed to avoid coating unevenness due to the flange bottom contacting the conveying roller 2A. Instead, the web is conveyed in the H position with the web width laid so that the lower end of the flange is supported by the conveyance roller 2A of the roller conveyor 2. For this reason, at the branch point to the coating line, a rollover means 40 is provided which rolls the H-beam on the L-arm 40A from the I position to the H position.

[0004]

In FIG. 5, for example, when a defective product is mixed in the H-section steel 1 conveyed on the roller conveyor 2 of the painting line, the defective product is quickly rejected (removed from the line) before painting. )There is a need to. However, looking at conventional equipment that can be applied to such rejection work of defective products, applying a crane, which is a very common suspension transfer means, requires excessive construction costs when a new dedicated crane is installed. It is impractical for existing cranes because of lack of timeliness. In addition, the rollover means 40 used at the branch point to the coating line in FIG. 5 is applied by rotating the L-shaped arm 40A in the reverse direction to the roller conveyor 2.
It is necessary to make the next H-shaped steel wait until it returns to below, and in each case, the flow of healthy products is hindered, and the coating productivity decreases. In addition, the application of the standing peg type conveyor 39 used in the drying furnace 33 is slow in operation and requires a large space in structure.

[0005] As described above, there is no device in the prior art that can smoothly perform the above-described rejection operation in an appropriate space. Therefore, an object of the present invention is to provide a rejection facility for an H-shaped steel capable of rejecting a fixed-length H-shaped steel conveyed in a longitudinal direction in an H attitude on a pass line while standing up to an I attitude in a short time as needed. And

[0006]

SUMMARY OF THE INVENTION According to the present invention, an H-shaped steel conveyed in a longitudinal direction on a roller conveyor in an H-position is picked up from the side at any time and rejected while being raised to an I-position.
What is claimed is: 1. A rejecting device for a shaped steel, comprising: a main shaft rod rotatable around its own axis along a longitudinal direction of the H-shaped steel; and a support surface fixed to the main shaft rod and supporting a side surface of the H-shaped steel at an end at an H position. A support arm equipped with a support lever capable of supporting the H-section steel in the H-position in front of the support surface and retracting to the side in a timely manner, and a roller track for landing the H-section steel raised in the I-position; The gist of the present invention is to provide a tiltable stopper that receives the landing H-shaped steel on the side opposite to the support lever, and a tiltable pusher that pushes the landed H-shaped steel from the support lever side to move laterally and return.

It is preferable that the roller conveyor has a side roller that can be turned upside down on a side where the H-section steel is rejected.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, "falling" means an operation of standing upright on a pass line of H-section steel and falling down below the pass line, and "pass line" conveys a predetermined route. Means the passing locus of the lower end of the transported object. FIG. 1 is a partially cutaway perspective view showing the outline of the present invention. In FIG.
1 is an H-section steel, 2 is a roller conveyor, 2A is a transport roller, 2B
Is a side roller, 3 is a spindle rod, 4 is a support arm, 4A
Is a support surface, 4B is a support lever, 5 is a roller track, 6 is a stopper, 7 is a pusher, 8 is a rotary drive source such as a rotary actuator, and 9 is a shaft.

The present invention will be described below with reference to FIG. The reject equipment of the present invention is provided beside the roller conveyor 2 and is rotatable around its own axis along the longitudinal direction of the H-section steel 1.
A support arm 4 having a support surface 4A for supporting the side surface of the H-section steel 1 in a posture, and supporting a H-section steel 1 in an H position in front of the support surface 4A and having a support lever 4B capable of retracting to the side at an appropriate time; Is provided.

The retracting mechanism of the support lever 4B is provided with, for example, a shaft 9 provided on the side surface of the support arm 4 at right angles to the axis of the main shaft rod 3 and the normal of the support surface 4A. The configuration can be made by fixing the tail end of 4B and rotating the shaft 9 by a rotary drive source (for example, a rotary actuator) 8. The reject equipment of the present invention further includes a roller track 5 for landing the H-shaped steel 1 raised in the I posture by the support arm 4 and a tiltable stopper for receiving the landed H-shaped steel 1 on the side opposite to the support lever 4B. 6 and a pusher 7 that can be moved upside down by pushing the H-shaped steel 1 that has landed from the side of the support lever 4B and returning.

The numbers of the support arms 4, the roller tracks 5, the stoppers 6 and the pushers 7 may be appropriately selected according to the length of the H-shaped steel 1. Since the present invention is configured in this manner, for example, in the positional relationship where the main shaft rod 3 looks at the roller conveyor 2 to the left, the support arm 4 is moved to the H-section
On the other hand, it was fixed to the main shaft rod 3 by setting the support surface 4A from the side and the support lever 4B from below (the standby position), and turning the main shaft rod 3 1/4 clockwise. The support arm 4 rotates clockwise, and the H-shaped steel 1 is supported by the support surface 4A and the support lever 4B, scooped up, and can be landed on the roller track 5 while being raised to the I posture.

Prior to landing, the pusher 7 is tilted down to raise the stopper 6 to prevent collision between the H-section steel 1 and the pusher 7 and to prevent tilting and tipping of the H-section steel 1 due to impact upon landing. Then, the pusher 7 is continuously raised, the stopper 6 is depressed, and the H-shaped steel 1 is pushed by the pusher 7 to be laterally moved to the storage location. On the other hand, the support arm 4 waits for the pusher 7 to stand up and then moves the support lever 4B to the support surface 4A.
After the H-section 1 is pushed by the pusher 7 and the support surface 4A is vacated, the main shaft rod 3 is turned counterclockwise 1 /.
4 to rotate the support lever 4B forward from the side of the support surface 4A with the rotary actuator 8 to return to the standby position, so that the support lever 4B H on 2
It does not cross the passage of the section steel 1.

Therefore, according to the present invention, the support arm 4 scoops up the H-beam 1 from the roller conveyor 2 at the same time as the next H-beam 1 without any extra waiting time for returning the support arm 4. Can be sent to the empty section. That is, as intended, the roller conveyor 2
Defective products contained in the H-section steel conveyed in the H position above can be quickly raised to the I position and rejected.

As for the pusher 7, after pushing the H-section steel 1 to the storage place, it may be returned to the pushing start position and fall down, and the stopper 6 is installed at a position corresponding to the flange width of the H-section steel 1. May be set appropriately. The roller conveyor 2 usually has side rollers 2B in addition to the transport rollers 2A.
This is caused to stand up against the H-section steel 1 from the side to prevent deviation from the predetermined passage. However, if the side roller 2B on the side where the H-section steel 1 is rejected is left standing, the side roller 2B may rub against the scooped H-section steel 1 or damage it or damage itself. As shown in FIG. 1, it is desirable to be able to be turned upside down and to be turned down during rejection work.
