Description

Detailed Description of the Invention (Industrial Application Field) This invention automatically removes a small amount of shot grains attached to the surface of a long steel material that has been subjected to surface treatment such as shot blasting. This invention relates to a stacking device for automatically stacking long steel materials without causing scratches when dropped.

(Prior Art) Conventionally, long steel materials are subjected to shot blasting as a surface treatment in order to increase their product value, and then these long steel materials are stacked in layers. Stacking is done using hoist cranes and other stacking robots, but when stacking using these devices, long steel materials tend to get scratched, and scratches can make them look unsightly. If the material deteriorates, it becomes a major hindrance to sales, so in order to stack the long steel materials without damaging them, the current situation is to rely on people to stack them manually.

(Problem to be solved by the invention) However, when stacking is performed manually, it is difficult for humans to do the work because the long steel materials themselves are very heavy.
It requires at least two workers, and the work is hard labor, creating a big problem in terms of working conditions and labor costs. There was also the problem that even though long steel materials were coming in at certain intervals, it was impossible to deal with them in time with manpower alone.

In addition, when the above surface treatment is applied, some shot grains, etc. are attached to the surface of the long steel materials, and when stacking the long steel materials, these short grains may get stuck between the long steel materials. There was also the big problem of scratches on the surface.

Therefore, in view of the above-mentioned problems, the present invention has been developed to process long steel materials that have been subjected to a surface treatment such as shot blasting and are continuously flowing without causing scratches due to shot particles or the like and scratches due to dents. It was created with the aim of making it possible to automatically stack stacks.

(Means for Solving the Problems) The present invention provides a loading machine for long steel materials, which is a conveying device such as a roller conveyor, and an inclined plate that is tilted in a direction perpendicular to the loading direction of the loading machine. an inclined pick-up device that picks up the long steel material transported to a predetermined position by the carry-in machine on a plate, and slides the long steel material on the inclined plate along the inclination until it abuts the contact stop member; A heald is looped around between two belt wheels, and the entire heald is formed to swing in the direction in which the belt is looped around one of the belt wheels or an appropriate position between them as a fulcrum, and this belt a pick-up and transfer device that picks up the long steel material that is stopped by abutting against the abutment stop member due to the swinging of the member and transfers it to a predetermined position; A suitable number of thin plate-shaped pull-out plates are picked up and moved in a direction away from the transfer device, and the pull-out plates are arranged on the side in the pull-out direction, and when the pull-out plates are pulled out, the pull-out plates are pulled out and moved. An abutment body that serves as a screen for the long steel material placed on and moved to abut against and remain in a predetermined position; and a lifting platform that lowers by the height of the long steel material or the height of the long steel material plus the thickness of the spacer each time the drawing plate moves. , which solves the above-mentioned problems.

(Function) The stacking device for long steel materials according to the present invention conveys the long steel materials to a predetermined position by a carrying machine including a conveyance device such as a roller conveyor.

Then, a tilt pick-up device that tilts the tilt plate in a direction perpendicular to the carrying direction of the carry-in machine is operated, and the transported long steel material is picked up by the tilt plate. Then, the long steel material slides along the slope on the inclined plate until it comes into contact with the abutment stop member, and the abutment with the abutment stop member, which is actually a light collision, causes
Powder from surface treatment adhering to the surface of long steel materials,
For example, shot particles in shot blasting are shaken off by the vibration of the contact.

Then, the long steel material in this state is picked up and transferred by a transfer device, which is formed by wrapping a belt between two belt wheels, to one of the belt wheels in the wrapping direction of the belt.
Alternatively, it is placed on the belt so as to be scooped by swinging the entire belt using an appropriate position between them as a fulcrum.

At this time, the long steel material is picked up and transported to a predetermined position by driving and rotating the belt that is wrapped around it.

The long steel materials transferred by this pick-up and transfer device are
At that position, it is placed on an appropriate number of thin plate-like pull-out plates, and is picked up and moved in a direction away from the transfer device so as to be pulled out. However, this transfer is performed after a plurality of long steel materials are sequentially placed on the drawing plate.

When the pull-out plate is pulled out after multiple long steel materials are placed one after another, the first long steel material that hits the abutting body remains in that state, and the next long steel materials are pulled out one after another. They come into contact with the long steel material they are in contact with and are lined up.

The long steel materials arranged in a predetermined position in this way are placed on a lifting platform placed below them, and the height of the long steel materials is increased each time the pulling plate moves. or the height of the long steel material plus the thickness of the spacer, and the remaining long steel materials are successively stacked.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a conveyance device such as a roller conveyor as a carry-in machine for the long steel material S, and it is placed between two parallel side frames 4 at an appropriate interval and above the side frames 4. A conveyance roller 2 that is rotatably supported and protrudes from the surface, and a motor 3 that drives and rotates the conveyance roller 2.
A sprocket 5 provided on each conveyance roller 2 and a sprocket 5 provided on the motor 3 are connected by a chain 6 to rotate each conveyance roller 2.

A tilt pick-up device is disposed on the side of the conveyance device 1.

This inclined pick-up device tilts the inclined plate 11 in a direction perpendicular to the carrying direction of the conveying device 1, and picks up the long steel material S that has been conveyed to a predetermined position by the conveying device 1 with this inclined plate. The inclined plate 11 is arranged between the conveying rollers 2 of the conveying device 11, and scoops up the long steel material S that has moved on the conveying rollers 2 by tilting it with the inclined cylinder 12. This is how it is taken up.

The long steel material S taken up in this way is
From the state where it slides down along the inclination at the top, it continuously moves across the obliquely disposed oblique fixing plate 13 and is slid until it abuts against the abutting stop member 14 having a shock absorber.

The long steel material S that has come into contact with this contact stop member 14 and has been stopped is picked up and transferred by a pick-up and transfer device 1 that is appropriately disposed between the inclined fixed plates 13 and has a belt looped between two belt wheels.
5 and transported to a predetermined position.

The specific structure of this pick-up and transfer device 15 is such that the entire belt is swung by a swiveling cylinder 18 with one of the belt pulleys or an appropriate position between them as a fulcrum in the belt looping direction. The long steel material S is stopped by coming into contact with the contact stop member 14 due to its swinging.
Take up.

Therefore, when the driving force of the motor 16 is transmitted through the drive shaft 17 to rotate the belt, the long steel material S is transferred to a predetermined position by the rotation of the belt.

The long steel material S transferred in this manner is placed on an appropriate number of thin plate-shaped drawing plates 19 whose tips extend to the end point of the transfer or before it.

When a plurality of long steel materials S are sequentially placed side by side on the pull-out plate 19 by repeating the above operations several times, the pull-out plate 19 is moved in a direction away from the pick-up and transfer device 115 so as to be pulled out. .

This movement of the pull-out plate 19 is achieved by the driving force of the motor 21 acting as a pulling motion of the tension chain 20 via the drive shaft 22, thereby moving the pull-out plate 19 connected to the pull chain 20.

Then, the elongated steel material S comes into contact with the abutment bodies 25 disposed on both sides of the pull-out plate 19 in the pull-out direction, forming a screen and remaining at a predetermined position.

Therefore, when the pull-out plate 19 is completely pulled out, the long steel material S that abuts against the abutment body 25 and remains at a predetermined position is
An elevating device arranged below it and lowered by the height of the long steel material S each time the drawing plate moves, or by the height of the long steel material plus the thickness of the spacer 24a described later. It is placed on the stand 26. The lifting table 26 is lowered by attaching the lifting table 26 to a lifting screw shaft 28 machined by a drive device 27.

When the first stage of the elongated steel material S is placed on the elevating table 26, the elevating table 26 is lowered by the height of the elongated steel material S. Next, the spacers 24a are placed so as to intersect with each other on the long steel material S of the -th stage, the long steel material S is stacked on top of the spacer 24a, and the spacer 24a and the long steel material S are placed on top of that.
Make sure to overlap them.

The spacers 24a are stacked in a storage cartridge 24 arranged behind the abutting body 25, and are pushed out from behind by an extrusion cylinder 23 in order starting from the lowest spacer 24a and placed on the lifting platform 26. It is sent out so as to cross over the long steel material S placed thereon.

It goes without saying that the present invention is not limited to the embodiments described above.

(Effects of the Invention) The present invention configured as described above includes a carrying-in machine for carrying long steel materials S made of a conveying device 1 such as a roller conveyor, and an inclined plate 11 that is tilted in a direction orthogonal to the carrying direction of the carrying-in machine. While doing so, the long steel material S that has been transported to a predetermined position by the carrying machine is picked up by the inclined plate 11, and the long steel material S is brought into contact with the contact stop member 14 along the slope on the inclined plate 11. A belt is looped between an inclined pick-up device and one or two belt wheels, and the entire belt swings in the direction in which the belt is wound around one of the belt wheels or an appropriate position between them as a fulcrum. a pick-up and transfer bag +115 that picks up the long steel material S that is stopped by abutting against the abutment stop member 14 due to the swinging of the belt and transfers it to a predetermined position;
An appropriate number of thin plate-like drawing plates 19 on which the long steel materials S transferred by the picking-up and transferring device 15 are placed and moved in a direction away from the picking-up and transferring device 15; When the pull-out plate 19, which is disposed on the side in the pull-out direction, is pulled out, the long steel material S placed and moved due to the pull-out movement of the pull-out plate 19 hits and remains in a predetermined position, forming a screen. It is arranged below the abutment body 25 and the long steel material S that abutted against the abutment body 25 and remains in a predetermined position, and is moved by the height of the long steel material S every time the pull-out plate 19 is pulled out, or By constructing the elevating table 26 which descends by a height equal to the height of the long steel material S plus the thickness of the spacer 24a, the following effects are achieved.

That is, a long steel material is conveyed to a predetermined position by a carry-in machine made up of a conveyor 1 such as a roller conveyor, and an inclined pick-up device is operated to tilt the inclined plate 11 in a direction perpendicular to the carrying direction of the carry-in machine. , the conveyed long steel material S is picked up by the inclined plate 11. Then, the long steel material S slides along the slope on the inclined plate 11 until it abuts against the abutting stop member 14, and lightly collides with the abutting stop member 14. As a result, powder from the surface treatment, such as shot grains from shot blasting, adhering to the surface of the long steel material S is shaken off by the vibration of the collision.

Therefore, on the surface of the long steel materials S to be finally stacked,
Since everything that causes scratches such as shot particles is removed, the causes of such scratches can be completely removed except for dents.

Then, the long steel material S is picked up and transferred by a pick-up and transfer device 15, which is formed by a belt being looped between two belt wheels, to one of the belt wheels or an appropriate position between them in the direction in which the belt is looped. By swinging the entire belt using the position as a fulcrum, the long steel material S is scooped up and placed on the belt. Transport it to the location. Then, the long steel material S transferred by the pick-up and transfer device 15 is placed on an appropriate number of thin plate-like drawing plates 19 at that position, and moved to be pulled out in a direction away from the pick-up and transfer device 19. This transfer is performed after a plurality of long steel materials S are placed one after another on the pull-out plate 19, and after the plurality of long steel materials S are placed one after another, the pull-out plate 19 is pulled out. Then, the abutting body 25
The long steel material that hit the object first remains in the state where it hit it,
The next long steel material S comes into contact with the previous long steel material S and is lined up, and these remaining long steel materials S stand 26
will be placed on.

Therefore, the long steel material S is placed smoothly on the lifting platform 26 without any major fall, and therefore is placed without any dents.

Therefore, this lifting platform 26 is lowered by the height of the long steel material S, or by the height of the long steel material S plus the thickness of the spacer 24a, each time the drawing plate 19 is pulled out. Therefore, the long steel materials S can be stacked one after another.

As a result, long steel materials that had been subjected to surface treatments such as shot blasting were continuously flowed.

This automatically stacks the stacks without causing scratches caused by grains or dents or the like.
