Description

The present invention relates to a chip chip removing device that removes chips, chips, etc. generated during processing by a machine tool. Furthermore, by using the wind power of the exhaust gas discharged from the mist collector, which is a device for sucking oil mist classified into particulate matter and separating it from air, as an air blow, when processing with a machine tool or the like. The present invention relates to a chip chip removing device for removing chips and chips generated in the air.

The mist collector is a device for sucking oil mist, which is mainly classified into particulate matter (gas material such as gas and steam, dust, fume, etc.) and separating it from air. Particulate matter generated by production activities in factories may pollute the working environment by floating in the air and cause health problems. (By the way, in machine tools, the cutting oil supplied to the cutting point during machining is turned into mist by the machining heat (generated during machining), but it should be installed to prevent it from floating by capturing it. For this reason, it is necessary to install and remove general ventilation and local exhaust equipment. Conventionally, the mist collector has been a local exhaust device for preserving the working environment.

On the other hand, unlike oil mist floating in the air, chips and chips are not collected by the mist collector, so chips and chips are processed in the processing room of the machine tool (when the machine tool is operating). Since it also accumulates on the machine cover part such as the shutter part that separates it from the outside, the worker blows off chips and chips with compressed air installed in the factory each time (accumulated). , I was working on removing chips and chips using tools such as air. It can be said that the work that takes time is unexpectedly time-consuming and disturbing work. Furthermore, it was necessary to stop the machine tool each time for cleaning, which was a factor that reduced productivity. Therefore, from the viewpoint of reducing the burden on the operator and from the viewpoint of productivity, a method and an apparatus for preventing chips, chips, and the like from accumulating on the upper part of the machine cover portion such as the shutter portion have been desired.

Patent Document 1 has an object of "preventing chips generated during cutting work of a work material from accumulating in the front region in the cutting direction", and "is formed in the main body housing and wind after cooling the motor". An exhaust port that discharges forward, an opening that is formed in the angular plate and guides the wind discharged from the exhaust port to the front region in the direction of movement of the base, and the wind discharged from the exhaust port blows the blade. It restricts the outflow of the base to the side in the moving direction through between the front end of the covering second region and one end of the angular plate so that the wind discharged from the exhaust port flows to the opening. A cutting machine (Patent Document 1: Title of the invention) having a structure having a regulation unit for promoting the above-mentioned is disclosed. That is, there is disclosed a cutting machine that uses the exhaust gas used to cool the motor of the cutting machine to blow off chips that are about to accumulate in the front region in the cutting direction.

Japanese Unexamined Patent Publication No. 2009-214292

The cutting machine according to Patent Document 1 (Patent Document 1: the name of the invention) is expected to have the effect of being able to blow off chips by using the wind power of the exhaust used for cooling the motor of the cutting machine. However, from the description "In the cutting machine, in order to prevent chips generated during the cutting operation of the work material from accumulating in the front region in the cutting direction ... (Patent Document 1: 0004 paragraph)". , The function of controlling the behavior of the exhaust gas discharged from the exhaust port is considered to be extremely limited from the description of "the front region in the cutting direction", and in the actual configuration, the exhaust gas flows out to the side. It only has a configuration that regulates that. In order to adapt to the removal of chips and chips generated during the operation of machine tools, it can be said that it is necessary to further devise a function to control the behavior of the exhaust gas (that is, the configuration until the exhaust gas is discharged). ..

An object of the present invention is to use the wind power of the exhaust discharged from the mist collector as an air blow, so that chips and chips are applied to the upper part of the machine cover portion such as the shutter portion that separates the processing chamber of the machine tool from the outside of the processing chamber. It is an object of the present invention to provide a chip removing device for preventing the accumulation of chips.

In order to solve the above problems, the invention according to claim 1 uses the wind power of the exhaust gas discharged from the mist collector to remove chips and chips generated during processing by a machine tool. It is a dust remover
Mist collector body and
A ventilation member connected to the exhaust port of the mist collector main body in order to send the exhaust gas discharged from the mist collector main body to a place where chips and chips are accumulated.
It is characterized in that it is a chip chip removing device characterized by having a ejection member for adjusting the flow of exhaust gas when removing chips and chips at the tip of the blower member.

The invention according to claim 2 is characterized in that, in claim 1, the blower member is a chip removing device having a branched tip side.

The invention according to claim 3 is the chip removing device according to claim 1 or 2, wherein the ejection member is a rectangular chip removing device in which the cross section of the ejection port is formed in a horizontally long rectangular shape with respect to the horizontal direction. It is characterized by.

The present invention is a chip chip removing device that removes chips and chips generated during processing by a machine tool by using wind power (exhaust) discharged from a mist collector. In order to send the air discharged from the mist collector body and the air discharged from the mist collector body to the place where chips and chips are accumulated, the blower member connected to the exhaust port of the mist collector body and the chips and chips are placed at the tip of the blower member. It is equipped with a ejection member for adjusting the air flow when removing.

Conventionally, the exhaust gas discharged from the mist collector has been discharged into the atmosphere as it is (see FIG. 1 (a)). On the other hand, if chips or chips accumulate on the upper part of the machine cover such as a shutter that separates the processing room of the machine tool from the outside of the processing room (see FIG. 1A), the operator needs to clean it regularly. there were. By guiding the exhaust from the exhaust port of the mist collector to the upper part of the machine cover such as a shutter via the blower member of the chip chip removing device and the ejection member, and discharging the exhaust from the ejection member, chips and chips are discharged. Can now be removed (see FIG. 1 (b)).

In short, the exhaust gas discharged from the mist collector is sent to a place where chips and chips are likely to accumulate via the blower member and the blower member (controlling the behavior of the exhaust gas discharged from the mist collector) and discharged. You can now do it. Since it is the removal of chips and chips by the wind power discharged from the mist collector (because the mist collector is always activated while the machine tool is in operation), the wind power (exhaust) discharged from the mist collector always activates the shutter. Since chips and chips do not accumulate on the upper part of the machine cover, cleaning by an operator is no longer necessary.

It is a figure for demonstrating the technical idea of the chip chip removing apparatus which concerns on this invention. It is a figure for demonstrating the use state of a chip removal apparatus. It is a perspective view and a side view seen from the front side of a blower member and a blower member. It is a figure for demonstrating the Example of the ejection member.

<Technical concept of chip removal device>
Hereinafter, an embodiment of the chip removing device 10 according to the present invention will be described in detail with reference to FIGS. 1 to 4. FIG. 1 is a diagram for explaining the technical idea of the chip removing device 10 according to the present invention. FIG. 1A is a diagram for explaining a usage state of a conventional mist collector, and FIG. 1B is a diagram for explaining the role of the mist collector in the chip removing device 10.

Before explaining the details of the chip removing device 10 with reference to FIG. 1, before the present invention is made, it occurs when a metal block as a workpiece is machined during operation of a machine tool. Explain what kind of state the chips and chips were in. Conventionally, the exhaust gas discharged from the mist collector has been discharged into the atmosphere as it is without being used as shown in FIG. 1 (a) (open to the atmosphere). Oil mist generated by cutting a metal block that is a work piece during operation of a machine tool is sucked together with air by a mist collector, and oil mist (harmful to the human body) etc. is sucked from the air through a filter. After removing the, only clean air is released into the atmosphere.

On the other hand, chips and chips generated by cutting a metal block, which is a work piece, were scattered and then accumulated in the surrounding area in a dropped state. Specifically, it was deposited on the upper part of the machine cover such as the processing chamber of the machine tool (around the spindle) and the shutter that separates the machining chamber of the machine tool from the outside of the machining chamber (see FIG. 1A). Therefore, the worker had to clean it regularly. It should be noted that the factors that cause chips and chips to accumulate on the upper part of the machine cover such as the shutter are the scattering of the work piece after processing by air blow, which is performed with the shutter open, and the transportation by the work piece transfer device. Examples include those in which chips and chips adhering to the work piece fall and accumulate on the upper part of the shutter.

Under such circumstances, a chip removal device is used to prevent the operator from having to regularly clean (the upper part of the machine cover such as a shutter that separates the processing room of the machine tool from the outside of the processing room). It has been developed. To put it simply, the principle of the chip removal device is that, as shown in FIG. 1 (b), by installing a duct or the like extending from the discharge port of the mist collector (conventionally, it is discharged to the atmosphere as it is). Using the clean air discharged from the mist collector, chips and chips that accumulate on the upper part of the machine cover such as the shutter that separates the machine tool's processing room from the outside of the processing room (before it accumulates) ) It can be said that it is an air blow device. Since the mist collector keeps operating while the machine tool is operating, it always blows air to partition the place where the machine tool is installed (specifically, between the machine tool's processing room and the outside of the processing room. The effect that chips and chips do not accumulate on the upper part of the machine cover such as the shutter can be expected (see FIG. 1 (b)).

<Usage condition and structure of chip removing device>
FIG. 2 is a diagram for explaining a usage state of the chip removing device 10. As described in FIG. 2, the chip removing device 10 is generated during processing by a machine tool by utilizing the wind force of the exhaust discharged from the mist collector main body 20 (not shown, the same applies hereinafter) (not shown). It is a chip chip removing device 10 for removing chips and chips (accumulated on the upper part of a machine cover such as a shutter that partitions between the processing room of a machine tool and the outside of the processing room). The chip chip removing device 10 connects the mist collector main body 20, which is an exhaust source, to the exhaust port of the mist collector main body 20 in order to send the exhaust gas discharged from the mist collector main body 20 to a place where chips and chips are accumulated. A blower member 30 to be connected and a blowout member 40 for adjusting the flow of exhaust gas when removing chips and chips at the tip of the blower member 30 (meaning "tip" along the flow of exhaust gas) are provided. ing.

When the chip chip removing device 10 is activated, as shown in FIG. 2, the exhaust gas discharged from the mist collector main body 20 causes a flow as described by an arrow (see FIG. 2), (machining of a machine tool). The chips and chips that are likely to accumulate on the upper part of the shutter (which separates the room from the outside of the processing room) will be removed by air blow. Specifically, the exhaust gas discharged from the mist collector main body 20 is divided in two directions on the tip side of the blower member 30 connected to the exhaust port of the mist collector main body 20. By the way, some machine tools have two spindles lined up in parallel, and when corresponding to such a model of machine tool, if the form is divided in two directions on the tip side of the blower member 30, it will be cut. It can be said that the effect of removing powder and chips is improved. The blower member 30 does not necessarily have to be branched on the tip side depending on the state of accumulation of chips and chips.

Further, the ejection member 40 for adjusting the air flow causes the flow to spread on a plane (see FIG. 2). In short, the local (extremely one-point concentrated type) exhaust immediately after being discharged from the mist collector main body 20 passes through the blower member 30 and the blower member 40, so that the flow spreads on a flat surface. It is unique in that. Below (with reference to FIG. 3), the local exhaust immediately after being discharged from the mist collector main body 20 passes through the blower member 30 and the blowout member 40, so that the flow spreads on a flat surface. Finally, a mechanism for discharging from the ejection port of the ejection member 40 to the upper part of the shutter (which partitions between the processing chamber of the machine tool and the outside of the processing chamber) will be described.

FIG. 3 is a perspective view and a side view of the blower member 30 and the blower member 40 as viewed from the front side. FIG. 3A is a perspective view seen from the front side, and FIG. 3B is a side view. The blower member 30 has a cylindrical shape as a base shape, is connected via connecting parts in order to change the angle (exhaust traveling direction) on the way, and the tip side is branched in the horizontal direction (viewed from the front). The overall shape is an inverted T shape: see FIGS. 3 (a) and 2). It should be noted that, again, the blower member 30 does not necessarily have to be branched on the tip side depending on the state of accumulation of chips and chips. The ejection member 40 is installed at an angle of 10 ° to 45 ° with respect to the horizontal direction at the tip of the blower member 30 (meaning “tip” along the flow of exhaust air), and ejects the member 40. It can be said that it is characterized in that the cross section of the exit is formed in a horizontally long rectangle with respect to the horizontal direction (extremely speaking, it is formed in a straight line).

The blower member 30 is a member that blows the local exhaust discharged from the mist collector main body 20 to the front of the blowout member 40 with a cylindrical cross section, and the blowout member 40 blows out the exhaust having a cylindrical cross section. It can be said that the member is a member whose cross section is converted into a horizontally long rectangle (a member which is converted into a flat exhaust). Explaining the ejection member 40 in detail, since the ejection member 40 is formed in a rectangular shape in which the cross section of the ejection port is horizontally long with respect to the horizontal direction, that is, it is formed in a straight line (extremely speaking). (See FIG. 3A), the exhaust spreads out in a plane and is discharged. The chip removing device 10 is designed so that the exhaust gas discharged from the mist collector main body 20 finally spreads in a plane and is discharged.

If the exhaust discharged from the mist collector main body 20 is discharged in such a state, it is possible to cover almost the entire upper part of the machine cover such as a shutter that separates the processing room of the machine tool from the outside of the processing room. It can be said that it is easier to obtain the effect of preventing chips and chips from accumulating on the upper part of the machine cover such as a shutter that separates the processing room of the machine tool from the outside of the processing room.

When the exhaust gas from the blower member 30 is blown to the blower member 40 and then discharged, the cylindrical cross-sectional area of the blower member 30 required to be discharged over the entire discharge port of the blower member 40, and The relationship between the cross-sectional areas of the rectangular spouts of the spouting member 40 will be described. Since the amount of exhaust gas passing through the blower member 30 per unit time is equal to the amount of exhaust gas discharged from the ejection member 40 per unit time, it is desirable to maintain the amount of exhaust gas passing through the unit area as much as possible. However, an object of the present invention is to prevent chips and chips from accumulating on the upper part of a machine cover such as a shutter that separates the processing chamber of the machine tool from the outside of the processing chamber. It suffices if the wind power that blows off the chips is secured.

In consideration of these matters, the relationship between the cross-sectional area of the cylindrical shape of the blower member 30 and the cross-sectional area of the rectangular spout of the ejection member 40 needs to be as follows. That is, the ratio of the cylindrical cross-sectional area of the blower member 30 to the rectangular cross-sectional area of the ejection member 40 is "cylindrical cross-sectional area: cross-sectional area of the spout = 0.1: 1 to 1: 1". It is desirable that it is "3.3". The cross section of the ejection port of the ejection member 40 has a dimensional ratio of portrait to landscape so that the exhaust gas discharged from the mist collector main body 20 spreads out in a plane and is discharged. Although it is designed to have a length of 12 to 1:16, it may have a horizontally longer shape (~ 1:25).

<Effect of chip removal device>
Conventionally, chips and chips generated by cutting a metal block, which is a work piece, are scattered and then processed as they are in the machine tool processing chamber (around the spindle) or in the machine tool processing chamber. It was accumulated on the upper part of the machine cover such as the shutter that separates it from the outside (see FIG. 1 (a)). The chip chip removing device 10 according to the present invention uses the exhaust of the mist collector to prevent chips and chips from accumulating on the upper part of the machine cover such as a shutter that separates the processing chamber of the machine tool from the outside of the processing chamber. It is characterized by being designed (specializing in chip removal points). The chip removing device 10 cuts the exhaust discharged from the mist collector main body 20 while controlling the behavior of the flow of the exhaust discharged from the mist collector main body 20 via the blower member 30 and the ejection member 40. By sending it to a place where powder and chips are likely to accumulate (the upper part of the machine cover such as a shutter that separates the machine tool's processing room and the outside of the processing room) and discharging it, it separates the machine tool's processing room from the outside of the processing room. It has become possible to prevent chips and chips from accumulating on the upper part of the machine cover such as a shutter.

Since the mist collector main body 20 is continuously operated during the operation of the machine tool so that the oil mist does not scatter in the factory, chips and chips and chips are continuously operated while the machine tool is in operation. Chips do not accumulate. Therefore, the technical aspect of the present invention is that the chip chip removing device 10 according to the present invention does not even have the concept of cleaning the upper part of the machine cover such as a shutter that separates the processing room of the machine tool from the outside of the processing room. It is significant.

Since the exhaust of the mist collector main body 20, which has been completely wasted until now, is used, the compressed air installed in the factory is not used, which is economical and energy-saving. In short, it can be said that it is a novel idea to use the exhaust of the mist collector main body 20, which has never been considered until now. As a result of the invention, each time a worker blows off chips and chips with compressed air installed in the factory, and removes chips and chips using a tool such as a broom. There is no need to do it at all.

The cylindrical cross-sectional area of the blower member 30 and the rectangular shape of the blowout member 40 so that the exhaust discharged from the mist collector main body 20 is discharged while ensuring the wind force that spreads on a flat surface and blows off chips and chips. The ratio of the cross-sectional area of the spout is "cylindrical cross-sectional area: cross-sectional area of the spout = 0.1: 1 to 1: 1.3", and the cross-section of the spout is the ratio of portrait to landscape. However, because it is designed to be vertically long: horizontally long = 1: 12 to 1:16 (in some cases (to 1:25)), the exhaust discharged from the mist collector main body 20 is (of the machine tool). It has become possible to obtain the maximum effect as a chip chip removing device 10 for preventing the accumulation of chips and chips (on the upper part of a machine cover such as a shutter that partitions between the processing chamber and the outside of the processing chamber). ..

<Example of chip removing device>
FIG. 4 is a diagram for explaining an embodiment of the ejection member 40 of the chip removing device 10 according to the present invention. In the ejection member 40 of the chip removing device 10, the exhaust gas discharged from the mist collector main body 20 spreads in a plane from the ejection port of the ejection member 40 (as described in FIG. 2) and is discharged. In addition, the outlet of the ejection member 40 can be narrowed for the purpose of amplifying the wind force. Specifically, by narrowing down the height of the ejection port of the ejection member 40 to 1/4 to 1/3 of the height of the main body of the ejection member 40 (narrowing toward the ejection port of the ejection member 40: FIG. 4, left side: 40 (1)), the exhaust gas discharged from the mist collector main body 20 is discharged from the ejection port of the ejection member 40 in a state where the wind power is amplified.

Then, the exhaust gas discharged from the mist collector main body 20 can be formed into a shape in which a number of small holes (side by side) are opened for the purpose of amplifying the wind power from the ejection port of the ejection member 40. That is, without opening the ejection port of the ejection member 40 completely, circular holes having a diameter of 1/4 to 1/3 of the height of the ejection port of the ejection member 40 are formed side by side. (See right side of FIG. 4: 40 (2)). Specifically, the actual size of the hole diameter is formed so that the holes having a diameter of 4 mm (which can be freely selected from to φ8 mm) are arranged side by side. In addition to forming the holes side by side in one row, the holes may be arranged side by side in two rows or in more rows. Further, instead of the holes, a plurality of vertically long slit-shaped gaps (width 4 mm to 8 mm) can be formed. By forming the ejection port of the ejection member 40 in this way, the exhaust gas discharged from the mist collector main body 20 is discharged from the ejection port of the ejection member 40 in a state where the wind power is amplified.

Further, by dividing the inside of the ejection member 40 by a partition plate (installed so as to be parallel to the flow direction of the exhaust), the exhaust discharged from the mist collector main body 20 is not biased, and the ejection port of the ejection member 40 is not biased. It is also possible to make it blow out (uniformly) with the same air volume. That is, by installing a partition plate inside the ejection member 40 and dividing the ejection port of the ejection member 40 into 10 to 20 areas, the flow of the exhaust gas discharged from the mist collector main body 20 can be adjusted (rectification). Action). The internal division (division method of the ejection port) of the ejection member 40 (by the partition plate) may be equal division or may have different widths, and can be freely selected.

<Example of changing the chip removal device>
The chip removing device according to the present invention is not limited to any of the above-described embodiments, and the configuration of the blower member, the ejection member, etc. is not deviated from the gist of the present invention as necessary. Can be changed as appropriate. For example, the tip end side of the blower member may be bifurcated or more. Then, a fixing member for fixing the ejection member to the upper part of the machine cover such as a shutter that separates the machine tool from the processing room to the outside of the machine tool is provided, and the fixing member is movable with respect to the machine tool. It is also possible to install a moving member that is installed so as to be. Further, an angle adjusting function may be provided at the joint between the blower member and the blower member, or the number of mist collector main bodies as exhaust generation sources is two (or more) and the number of mist collector main bodies is two (or more). ) May be aggregated and the exhaust may be blown in a manner that increases the air volume.

Since the chip chip removing device according to the present invention has an excellent effect as described above, chips are prevented from accumulating chips and chips generated during processing by a machine tool or the like. It can be suitably used as a chip removing device.
