BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing chips that have fallen on a shaped steel such as an H-shaped steel by working with a drilling machine or the like.

[0002]

2. Description of the Related Art In a punching machine such as a drill punching machine or a cutting machine such as a band saw, which processes a shaped steel such as an H-shaped steel, processing data is input in advance due to computerization of control in recent years. As a result, it has become possible to continue processing automatically while sizing short materials and long materials without long materials, and unmanned operation is possible with a single processing machine.

In order to automatically make a line from a drill type drilling machine having such an automatic operation function and a band saw machine and automatically perform drilling to cutting, as shown in FIG. If the chips d accumulated on the upper surface of the web w of the shaped steel h such as H-section steel are not removed before the cutting process, there is a risk of chipping or bending when the saw blade cuts the chips.

Conventionally, as a method of removing the chips accumulated on the surface of the H-shaped steel web, 1) a method of blowing off with an air blow, 2) a method of sucking with a vacuum cleaner, etc. 3) a method of pushing away with a scraper-like plate 4) a wire brush 5) Method of rotating and sweeping away the wire 5) There is a method of hanging the wire W in a comb shape and pushing it away as illustrated in FIG.

[0005]

By the way, the method of blowing off by the air blow shown in 1) has no effect on large and heavy objects such as chips of a drill having a diameter larger than a certain extent. Further, in the method 2) for sucking up with a vacuum cleaner, the size of the apparatus is large and a device for moving the suction port is required, which is a problem in economic efficiency.

Furthermore, the method of pushing back with a scraper-like plate of 3) is not practical because the width of the scraper must be replaced every time the width of the H-section steel changes. Furthermore, in the method of rotating and sweeping away the wire brush shown in 4), not only the power for rotation is required and the apparatus becomes large-scaled, but also the width of the H-section steel is changed as in the method of 3). I can't handle it.

The method 5) of dropping the wire W into a comb shape and pushing it away is inexpensive and can cope with a change in the width of the H-section steel. However, when pushing away the accumulated chips d, it gradually becomes flat in FIG. As shown in the figure, the chips d leak from both sides of the wire W, and there is a problem that the chips cannot be completely removed and collected in the chip receiving box B. The present invention has been made in view of such a point, and it is possible to easily remove chips on the web surface of a shaped steel, which could not be easily removed by the conventional method, in the transportation process based on a simple structure. The purpose of the present invention is to provide a chip removing device.

[0008]

In order to achieve the above object, a chip removing device for a web surface of a shaped steel of the present invention is arranged in a direction substantially orthogonal to a conveying direction of a conveying device and has a predetermined width. At least one vertical brush formed by hanging a wire in a comb shape, and provided on the downstream side or the upstream side in the transport direction with respect to the vertical brush, and extending the wire in a left-right direction when viewed from the transport direction in a V shape. It is characterized in that a pair of oblique brushes, an interval adjusting means for adjusting the mutual interval of the oblique brushes, and an up-down adjusting means for adjusting the vertical position of the vertical brush and the oblique brush are provided.

[0009]

It has been confirmed by experiments conducted by the present inventors that the chips that have fallen on the shaped steel and which are particularly difficult to remove are the intersections with the flanges on both sides of the web. In consideration of this point, the present invention is based on the simplest method 5) of the above-mentioned conventional chip removing methods, and the chips on both sides of the web that remain only through the interdigital wire. Is to be removed by a pair of diagonally V-shaped oblique brushes provided on the downstream side or the upstream side of the comb-shaped vertical brush.

That is, the interval between the pair of diagonally V-shaped oblique brushes provided on the downstream side or the upstream side of the comb-shaped vertical brush is made variable by the interval adjusting means, and both tips of the oblique brush are set. Is positioned on both sides of the web in response to changes in the width dimension of H-section steel, etc., so that the chips remaining on both sides of the web after passing through the vertical brush are trapped by the pair of oblique brushes. When the steel has finished passing through the vertical and oblique brush locations, almost all of the chips on the web will fall from the ends of the shaped steel and are easily removed during the transport process.

[0011]

Embodiment FIG. 1 is an external perspective view of an embodiment of the present invention, showing the present invention mounted on a conveying device 20 such as a roller conveyor. The transfer device 20 transfers the H-section steel h or the like in the direction indicated by the arrow in the figure. The gate type frame 10 arranged so as to straddle the transfer device 20 has two upstream and downstream sides.
Two vertical brushes 1 and 2 and a pair of oblique brushes 3 provided therebetween are supported.

The vertical brushes 1 and 2 on the upstream side and the downstream side have a comb shape in which wires are linearly planted over a predetermined width on a frame body 11 which is vertically displaceable on a gate type frame 10. The width dimension thereof is longer than the maximum width of the shaped steel web which can be conveyed by the conveying device 20. The oblique brush 3 is a guide rod 1 fixed to the frame body 11 described above.
2 is composed of a pair of brushes 3a and 3b in which wires are obliquely planted in blocks 14a and 14b, respectively.
When viewed from the transport direction of 0, the respective tips are arranged so as to spread downward, that is, are arranged in a substantially V shape.

The gate-shaped frame 10 is provided with a pair of left and right screw rods 15a and 15b, and the frame body 11 is screwed into the screw rods 15a and 15b to form screw rods 15a and 15b.
The frame 11 is displaced in the vertical direction by the rotation of b. A handle 16 is disposed on the upper portion of the gate-shaped frame 10, and by rotating the handle 16, the screw rods 15a and 15b are simultaneously rotated in the same direction by, for example, a bevel gear mechanism, and the frame 11 is moved up and down. Can be displaced in any direction.

The block 14a in which the one brush 3a of the oblique brush 3 is implanted is fixed to the guide rod 12, while the block 14b in which the other brush 3b is implanted slides on the guide rod 12. The screw 17 is provided freely and is screwed to a screw 17 rotatably supported on the frame 11. A handle 18 is fixed to one end of the screw 17, and by rotating the handle 18, the block 14b is displaced in the horizontal direction along the guide rod 12,
Thereby, the mutual distance between the brushes 3a and 3b is changed. The position of the tip of the fixed brush 3a in the direction orthogonal to the carrying direction is set to be substantially equal to one end of the vertical brushes 1 and 2, and the tip of the brush 3a is located at the reference position side of the carrying device 20. There
The web w of the shaped steel to be conveyed is located on one side portion (corner portion with one flange portion f _A ) of the upper surface. Further, in the displacement range of the brush 3b on the moving side, the distance between the tips of the brushes 3a and 3b is
The range is from the minimum web width dimension to the maximum web width dimension of the shaped steel conveyed by. A chip receiving box 19 is arranged below each brush.

In using the above-described embodiment of the present invention, the vertical brushes 1 and 2 are rotated by rotating the handle 16.
And the web w of shaped steel to be conveyed by the tip of the oblique brush 3.
The frame body 11 is positioned so that the upper surface of the brush 11 is sufficiently rubbed, and when the handle 18 is rotated, the tip end of the brush 3b on the moving side of the oblique brush 3 is to be conveyed by the shaped steel web w.
Side portion of the side opposite to the reference side (the other flange portion f _B
Position it so that it abuts on the corner). As a result, as shown in FIG. 2, both tip portions of the brushes 3a and 3b rub against both side portions of the upper surface of the shaped steel web w.

When the H-shaped steel or the like is conveyed on the conveying device 20 in the above-mentioned setting state, the chips d on the upper surface of the web w of the shaped steel, for example, by processing by a drilling machine or the like are illustrated in a plan view in FIG. As described above, first, the vertical brush 1 on the upstream side is caught, and the chips d left on both side portions thereof are caught by the succeeding oblique brush 3. In addition, the chips d slightly left on the web w even after passing through each of these brushes are
Captured by the vertical brush 2 on the downstream side of the next stage, and finally, almost all the chips are dropped and collected in the chip receiving box 19 therebelow when the shaped steel passes through these brushes.
It does not reach the band saw machine in the next process.

The points to be particularly noted in the above-described embodiment of the present invention are that no power unit is used and that the size of the shaped steel conveyed on the conveying device 20 is adjusted by a simple adjustment. The point is that the chips can always be almost completely recovered. In addition, the vertical position adjustment mechanism of each brush,
The space adjusting mechanism for the oblique brush is not limited to the above-described embodiment, and it is needless to say that another known mechanism such as a rack and pinion mechanism can be adopted.

Further, it is not necessary to provide two vertical brushes in particular, and it suffices to have at least the vertical brush on the upstream side, but it is also desirable to provide the vertical brush on the downstream side in order to complete recovery. Further, even if the oblique brush is provided on the upstream side of the vertical brush, substantially the same effect can be obtained. Furthermore, the thickness and length of the wire of each brush are not particularly limited, but it is preferable to select an appropriate one according to the size, type and amount of the chips on the web.

[0019]

As described above, according to the present invention, at least one vertical brush extending in the direction orthogonal to the direction of conveyance of the shaped steel by the conveying device, and the vertical brush in the conveying direction downstream or upstream of the vertical brush. In addition to providing a pair of oblique brushes in the shape of a mold, a means for adjusting the distance between the oblique brushes and a means for adjusting the vertical position of the vertical brush and the vertical position of the oblique brush are provided, and the vertical position of each brush and the distance between the oblique brushes. Is simply adjusted according to the dimensions of the profile steel to be transported, and regardless of the size of the profile steel, the chips on the web are almost completely removed without remaining.
Moreover, it does not require the use of power unlike the conventional chip removing method, and has a very simple structure, even if it is a large chip due to a large-diameter drill, etc. It is possible to remove reliably according to dimensional changes, an inexpensive and easy-to-use chip removing device can be obtained, and it contributes to the unattended operation of the fully automatic line from piercing to cutting of shaped steel. .
