Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a method for forming a flaw on a surface of a base material by using, for example, spatter or rust attached to the surface of a metal plate or "burrs" generated by cutting. The present invention relates to an apparatus for cleaning the surface of a flat article that can be peeled off without being attached.

(Prior Art) Conventionally, when cutting a steel plate or the like, fusing performed using a gas welding torch is widely used because it is general-purpose. Recently, a plasma fusing method has been adopted. Of course, a shearing operation using a shearing machine is also employed, but in the case of a thick plate, it is often cut off. In particular, since the fusing operation is convenient because the steel sheet can be cut into a shape suitable for the purpose, the fusing operation is mostly performed by a fusing method.

According to such a cutting method, it is inevitable that spatters and slag generated at the time of fusing around the cut portion adhere to the surface of the steel sheet, and therefore, it is necessary to remove the spatters and the like that have adhered.

Conventionally, such deposits such as spatters have been removed using tools such as rags.

(Problem to be Solved) In the work of removing spatter and slag adhered to the surface of the steel sheet as described above, an operator usually manually removes and removes using a tool such as a rag or a grinder. However, the degree of welding of the slag generated by the plasma fusing method is more difficult to remove than the gas fusing method and it is difficult to remove the slag. In addition, the more difficult it is to remove and remove slag and the like, the more the base material will be damaged, which will cause trouble.

Further, if the cleaning work of the surface of such an article is performed directly by hand, the work environment is inevitably poor, so that the problem of safety and health must be solved.

SUMMARY OF THE INVENTION The present invention solves these problems and eliminates the problem of safety and hygiene without cleaning the surface of an article to be processed directly by hand with mechanical force and without damaging the base material. Therefore, an object of the present invention is to provide a device which can be implemented efficiently.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides at least a pair of upper and lower adhering substance scraping rollers supported by a main body frame and driven to rotate, and A supporting device, and a conveyor for transferring the workpiece, which is provided at a position before and after in the moving direction of the workpiece with respect to the pair of the attached matter scraping rollers, wherein the attached matter scraping roller winds a rope around its peripheral surface. The upper scraping roller and the lower scraping roller are driven so as to generate a peripheral speed difference, and the workpiece is moved while being nipped by both scraping rollers. It is characterized by having comprised in.

In the apparatus of the present invention, the adhering matter scraping roller pair includes:
A plurality of sets of these should be arranged at appropriate intervals to perform the scraping work in multiple stages, and the ropes wound around the peripheral surface of the rollers should have the winding direction of the upper roller and the lower roller reversed. Thus, skewing during the movement of the article can be prevented, which is preferable.

Further, by providing a mechanism for removing the adhering matter peeled off by the roller at an appropriate distance from the adhering matter scraping roller pair, the foreign matter once peeled off is removed again by the scraping roller and the surface of the article. This is preferable because it can be prevented from being caught in between and damaging the surface of the article.

Further, as another aspect of the present invention, an endless roller formed by arranging a pair of upper and lower rollers supported by a main body frame and rotatably driven at a required interval and including a rope on each of the upper and lower roller pairs. A belt is wrapped around to form an adhering matter scraping mechanism, and one of the upper roller pairs is moved up and down by a pressing mechanism attached to the main body frame, and the workpiece is inserted and moved between the two endless scraping belts. This is characterized in that it is configured to be able to remove the adhered matter.

(Operation) The apparatus of the present invention moves the object while pressing and holding the object from above and below by an adhering substance scraping roller in which a rope is wound around the outer periphery rotating at different peripheral speeds.
The object to be processed moves while slightly slipping at the contact portion with each of the scraping rollers, so that, for example, spatter or slag adhering to its surface is wound around the rollers. It is scraped off by sliding on the rope, and is peeled off without damaging the surface of the base material. In particular, by using a rope formed of stranded wire in the part where this scraping operation is directly performed, a large number of strands forming the rope come into contact with the surface to be treated, and moderate elasticity and countless irregularities Is brought into contact with and rubs the surface to be treated, so that an effect of agitating the adhered substance can be expected, and the treatment can be performed without damaging the surface to be treated.

Further, according to the gist of the present invention, in addition to the independent scraping roller pair, a rope-woven belt can be used as an endless belt to perform the same processing as described above.

Further, the adhered matter separated by the pair of scraping rollers is separated and scraped out, for example, by providing a scraping debris removing mechanism adjacent to the roller, and then quickly removed to the outside. Therefore, there is no possibility that the base material surface is scratched by being attached again or being caught in the scraping portion by the scraping rollers provided in multiple rows.

Depending on the material to be treated, the rope to be wound around the adhering substance scraping roller can be selected from a wire rope or a fiber rope.
Easily removes oxide film (rust) or cutting burrs attached to wood after processing.

(Effects of the Invention) As described above, according to the apparatus of the present invention, it is possible to automate the operation of removing inconvenient deposits and the like on a steel plate or the like, which had a lot of difficulties in the conventional operation, with a device having a simple configuration, In addition, it can be said that the efficiency can be improved without damaging the base material, which is useful for omission.

(Embodiment) Hereinafter, the apparatus of the present invention will be described in more detail with reference to the embodiments and the drawings.

FIG. 1 and FIG. 2 show a first embodiment of the present invention, which is an apparatus for cleaning deposits on a steel plate,
A body frame 11 erected in a gate shape with a required width on the upper side, and at least one set of at least one pair of bearings 12 and 13 attached to the body frame 11 and having both ends supported vertically. The adhering substance scraping rollers 20, 20A and the scraping rollers 20, 2
A pressing mechanism 30 for applying a pressing force to 0A, a scraping chip removing mechanism 40 provided before or after or in close proximity to the scraping roller 20, and a conveyor 50 for supplying / discharging an object to be processed. It is configured.

As for the main body frame 11, two sets of frame-shaped frames arranged at appropriate intervals are arranged in a row in the moving direction of the object to be processed, and are connected to each other by a connecting member 15 at an upper portion thereof.

The adhering substance scraping rollers 20, 20A are attached to the main body frame.
Both ends at bearings 12 and 13 provided on 11, lower scraping roller 20A is rotatably supported at a fixed position,
The upper scraping roller 20 is supported to be vertically movable. As shown in FIG. 3, each of these scraping rollers 20, 20A has a rope groove 21 spirally engraved at a predetermined pitch on the outer peripheral surface thereof, and a wire rope 22 is formed along the rope groove 21. Are wound, and both ends of the roller 20 are
Or it is fixed to the end of 20A. In addition, this rope 2
The winding lead 2 can be arbitrarily selected. In addition, the upper scraping roller 20 and the lower scraping roller
The winding direction of the rope 22 is opposite to that of 20A. In this way, by reversing the winding direction of the rope 22 up and down, it is possible to prevent the traveling direction from shifting when the workpiece A is moved.

The two support bearings 13 of the above-mentioned scraping roller 20 are connected to a scraping roller pressing mechanism 30 originally disposed at the top of the frame 11, for example, a piston rod 32 of two sets of air cylinders 31. It moves up and down the required dimension along the sliding part 16 and also
The pressure is applied across the object A by 0A.

In this embodiment, two pairs of the above-mentioned scraping rollers 20, 20A are disposed at appropriate intervals. Each scraping roller 20, 20A pair has the same configuration,
The gears 24, 25 attached to the ends of the respective support shafts are made to mesh with each other, and one of the rollers is concerned so as to have a higher peripheral speed than the other roller. It is made to rotate. In addition, the scraping effect can be enhanced by setting the speed of one of the pair of scraping rollers 20 and 20A to be slightly faster than that of the other if necessary. The power to these two pairs of scraping rollers is driven independently of each other or by receiving power from one motor.

On the front side (the right side in the figure) of the upper scraping roller 20 of the above-mentioned attached matter,
As shown in FIG. 4 in parallel with the roller shaft,
A belt 41 with a brush that protrudes longer on both sides than the width of 11 and circulates and rotates is installed. The brushed belt 41 is configured to be driven at an appropriate speed by a driving force from a driving device 44 on one of the winding pulleys 42 and 43, and is originally provided on one side of the frame 11. The scraps are collected through the cut 45 and collected in a box.

The conveyor 50 for the object A can be of any type such as a belt type or a roller type. Both the supply side and the unloading side are driven at a constant speed.

In the apparatus of the present invention having such a configuration, if the gas-fused steel plate (object to be processed) A is supplied on the conveyor 50, it is first sent between the first pair of scraping rollers 20, 20A.
At this time, the distance between the upper scraping roller 20 and the lower scraping roller 20A is set in advance by the air cylinder 31 of the pressing mechanism 30 so as to correspond to the thickness of the steel plate of the workpiece A. It is. The workpiece A sent between the upper and lower scraping rollers 20, 20A is applied to the surface by a wire rope 22 wound around the peripheral surfaces of the scraping rollers 20, 20A rotating at high speed in the direction of the arrow. The attached slag and spatter will be scraped off.

At this time, the workpiece A is held by the air cylinder 31 of the pressing mechanism 30.
An upper scraping roller 20 to which a pressing force has been applied,
Both scraping rollers 2 sandwiched between the scraping rollers 20A at the lower fixed position and having different peripheral speeds
Wire rope 22 spirally wound at 0,20A
As a result, the deposit a such as slag is rubbed off by the frictional force and peels off, and the deposit is peeled off in the gap formed between the adjacent wire ropes 22 just wound around the roller. a is squeezed,
It will be discharged outside.

In this way, the adhered material that has been scraped off by the scraping rollers 20, 20A is peeled off, that is, debris is dropped as it is when the lower surface of the workpiece A is replaced, and the upper surface is adjacent to the scraping roller 20. Scrap removal mechanism provided
Due to the running of the 40 belts 41 with brushes, the workpiece A is quickly swept outside from the top of the workpiece A and sent without remaining on the surface.

Deposits that could not be removed by the first pair of scraping rollers 20, 20A are processed and stripped and removed by the next pair of second scraping rollers 20, 20A in the same manner as described above. . Then, after the operation of removing the adhering matter is completed, it is carried out by the conveyor 50 on the carry-out side.

As described above, the object A is separated and removed by the raking operation by the wire rope 22 wound around the roller.
Since it is not so-called hitting or scraping, the surface is not scratched, and it is not necessary to directly process it by hand, so that it can be omitted. Of course, workability will also be improved.

In order to enhance the peeling effect, the scraping rollers 20, 20A
It is desirable to increase the lead angle of the wire rope 22 wound around the wire as much as possible. In addition, scraping rollers 20, 2
If the peripheral speed difference of 0A and the relationship between the rotation speed of the roller and the moving speed of the processing object can be adjusted according to the processing state, it is possible to find the optimum condition and work. Further, it is possible to increase the number of pairs of the scraping rollers 20, 20A more than the above example. In this case, it is possible to set the rotation speed of each scraping roller pair to different conditions.

Further, instead of the brush belt type of the above-described example, the suction nozzle may be disposed in parallel with the scraping roller 20 and the scraping-off dust removing mechanism 40 may be removed by a suction force. According to this method, dust generated by the scraping operation can be simultaneously removed by suction, which is useful for improving the working environment.

Next, FIG. 3 shows a second embodiment, in which the front and rear spaces of the main body frame 11 erected in the same manner as in the previous embodiment are slightly widened, and the front and rear struts 11 'are provided with a peripheral surface. Two sets of rollers 26, 26A that do not wind the wire rope around
An endless belt-shaped scraping belt 28 formed by weaving a wire rope 27 to a required width is wound around the lower rollers 26A, 26A and the upper rollers 26, 26, respectively.
The pressing force of the air cylinder 31 of the pressing mechanism 30 is applied to each, and intermediate pressing rollers 29, 29 are provided at an intermediate portion of the upper and lower scraping belts 28 on the side facing the workpiece. .

For this type of equipment, the upper and lower scraping belts
28, 28 are configured to be driven so that their peripheral speeds are different. Further, it is desirable that a scraping-off-removing mechanism 40 be provided on the sending side in the same manner as described above.

As the scraping belt 28, a thin wire rope woven with a relatively coarse texture is used as long as it can be used as an endless belt. Of course, it is not limited to this.
If possible, it is preferable that the weft is woven so as to be inclined.

According to such an apparatus, when the processing object A supplied by the conveyor 50 is fed between the pair of scraping belts 28, 28, the two scraping belts 28, 2 which rotate with a speed difference.
While the object A moves while slightly slipping due to 8, the wire rope 27 constituting the scraping belt 28
As a result, the attached matter a is agitated, peeled off, and discharged to the outside. The separated debris moves to the outside while being sandwiched between the textures of the scraping belt 28. Accordingly, the lower scraping belt 28 is wiped off by a brush roller 46 or the like in the return stroke, and the upper scraping belt 28 is removed.
28, like the lower side, removes debris adhered by the brush roller or the suction nozzle 47, and prevents the workpiece A from being damaged in the next step.

According to the apparatus of the present invention, not only removal of slag and spatter of the blown steel sheet as described above, but also removal of burrs attached to the edge of the cut hole when drilling holes, removal of rust from the rusted plate. It can be used to do, etc.

When the object to be processed is a material other than a metal plate such as a steel plate, for example, wood, the object can be achieved by using a fiber rope instead of a wire rope. Of course, the scraping rope is worn, so if the wire breaks, it can be replaced with a new one. Furthermore, in the thing used as a scraping belt,
It is also possible to use a single wire instead of a wire rope.
