2. Description of the Related Art The basic structure of any of these conventional dust removing devices is that a desired pipe is connected to an air intake side such as a blower or the like, and a continuous connection is made from the opening at the tip of the pipe. This is merely a configuration in which the dust on the surface to be dust-removed is sucked into the pipe and collected by performing the appropriate air suction.

[0003]

SUMMARY OF THE INVENTION In the above prior art,
Since the dust is merely sucked by the air suction force of a blower or the like, dust adhering relatively firmly to the dust removal target surface cannot be removed, and the dust removal ability is inferior. Was. Conventionally, for example, in Japanese Patent Publication No. 58-55834, a pulsating low-frequency sound wave having a high vibration pressure, that is, an air pulsating wave, is useful as a means for removing soot and the like attached to a boiler or a blast furnace. Is suggested. However, such an invention merely provides a pulsation wave generating device that generates a pulsation wave of a positive pressure in which the exhaust of compressed air is intermittently performed. The dust on the target surface is scattered around the target. Therefore, it is not possible to properly collect dust, and for example, it is not suitable for applications in which dust attached to the surface of a sheet material is appropriately removed during the transfer process of the sheet material and collected. Yes, not practical.

The present invention has been proposed in view of the above points, and can appropriately remove and collect dust even if the dust is relatively firmly adhered to the dust removal target surface.
To provide a dust removal device that demonstrates excellent dust removal capability,
That is the purpose.

[0005]

According to the present invention, the dust is not removed by merely continuous air suction or the transmission of a positive pressure air pulsation wave as in the prior art. By using a negative pressure air pulsation wave in which the suction force acts intermittently,
The invention has been invented based on a completely new idea of recovering the removed dust, which has not been seen before.

That is, a dust removing apparatus according to the present invention is connected to an air pulsation wave generator for generating a negative pressure air pulsation wave and an air pulsation wave generation port of the air pulsation wave generation apparatus. The air suction path is intermittently sucked from an air inlet formed at the front end side of the air suction path so that dust on the surface to be removed is sucked into the air suction path and collected. In the configuration, the air pulsation wave generator particularly blows air in the air suction path to generate a negative pressure in the intake port, and intermittently blocks and opens a part of the suction path of the blower. And a pulsation imparting device for generating pulsation in the air sucked into the air suction path from the intake port.

According to a second aspect of the present invention, in the dust removing apparatus, a filter having air permeability for collecting dust sucked from an air inlet is provided in the air suction path.

According to a third aspect of the present invention, there is provided a dust removing apparatus, wherein the pulsation imparting device includes a casing having an air pulsation wave generating port and a blower connection port connected to the air suction side of the blower. A valve is provided rotatably in the casing and intermittently shuts off and opens an air flow path from the air pulsation wave generation port to the blower connection port by its rotation operation.

According to a fourth aspect of the present invention, there is provided a dust removing apparatus according to the present invention, wherein an intermittent air discharge is provided at a position inside or outside an intake port so as to transmit a positive pressure air pulsating wave to a surface to be dust removed. Exhaust port is provided.

[0010] In the dust removing apparatus according to the present invention, the suction port is disposed so as to face the sheet-like or panel-like dust-removing object to be conveyed, and the dust on the material surface can be removed. Is configured to be performed.

According to a sixth aspect of the present invention, there is provided a dust removing apparatus according to the present invention, wherein air discharging means for discharging compressed air in a direction of separating a sheet-shaped or panel-shaped object to be removed from the intake port beside the intake port. Is provided.

According to a seventh aspect of the present invention, there is provided a dust removing apparatus according to the present invention, wherein a sheet-shaped or panel-shaped dust removing object is provided at the position of the intake port so as to prevent the dust removing object from being attracted to the intake port. A press roller that rolls in contact with the surface is provided,
A brush having a function of removing static electricity is provided on the surface of the pressing roller.

In the dust removing apparatus according to the present invention, a static electricity removing brush which comes into contact with the surface of a sheet-like or panel-like dust removing object is provided at a position preceding the intake port.

According to a ninth aspect of the present invention, the air pulsating wave generator and the filter are accommodated in a portable case, and the air suction path is connected to the outside of the case. Hoses, all of which are configured as a vacuum cleaner.

[0015]

In the dust removing apparatus according to the present invention, the negative pressure air pulsation wave generated by the air pulsation wave generating device is removed from the air inlet of the air suction path. It can be transmitted to the surface. Therefore, an effect of peeling off dust adhering to the dust removal target surface by such air pulsation, that is, air vibration, can be obtained. Also,
The air pulsation wave has a negative pressure, and a suction force can be generated at the intake port, so that the dust separated on the surface to be dust-removed can be directly sucked into the air suction path and collected. As a result, the dust adheres relatively firmly to the surface of the object to be dusted, and dust that could not be removed by mere continuous suction can be appropriately peeled and removed, and such dust scatters around. It can be appropriately collected without causing any harm.

Further, in a state where the air in the air suction passage is continuously sucked by the blower, a part of the suction passage of the blower is intermittently shut off and opened by the pulsation imparting device, so that the air is sucked from the air inlet. Pulsation can be generated in the air sucked into the passage, whereby a negative pressure air pulsation wave can be appropriately generated. Thus, in the generation of an air pulsation wave using such a blower,
By increasing the suction and exhaust pressures of the blower, the vibration pressure of the air pulsation wave can be easily increased, and an air pulsation wave having a high vibration pressure can be obtained with a simple configuration.

In the dust removing apparatus according to the second aspect of the present invention, dust collected in the air suction path can be appropriately captured and collected by a predetermined filter.

In the dust removing apparatus according to the third aspect of the present invention, by rotating a predetermined valve body in the casing of the pulsation applying apparatus, the casing from the air pulsation wave generating port to the blower connecting port is provided. Air flow path can be intermittently blocked and opened, thereby causing pulsation of air sucked from the intake port into the air suction path,
A pulsation wave of a negative pressure can be appropriately generated. Therefore, if a pulsation wave is generated by the rotation of the valve element in the casing, the pulsation imparting device can be reduced in size without increasing its size, and its mechanical vibration and noise can be suppressed. Becomes

In the dust removing apparatus according to the present invention, the air pulsating wave of negative pressure can act on the surface to be dust-removed from the intake port, and at the same time, the exhaust gas provided separately from the intake port is provided. Air pulsation waves of positive pressure can be transmitted from the mouth to the dust removal target surface. Therefore, in addition to the dust separating action by the negative pressure air pulsating wave, the dust separating action by the positive pressure air pulsating wave is obtained, and an excellent dust removing action can be obtained.

In the dust removing apparatus according to the fifth aspect of the present invention, if the sheet-like or panel-like dust removing objects are sequentially transferred at a position facing the intake port, these sheet-like or panel-like dust removing objects are transferred. Dust attached to the surface of the object can be appropriately removed and collected. In such a case, in the dust removing apparatus according to the present invention, the compressed air is discharged from the predetermined air discharging means to the dust removing target, and the dust removing target is separated from the intake port. be able to. Therefore, it is possible to appropriately prevent the sheet-shaped or panel-shaped dust-removing object itself from being sucked toward the intake port and coming into contact with the intake port to be damaged.

In the dust removing apparatus according to the present invention, the sheet-like or panel-like dust-removing object is pressed by the pressing roller, so that the dust-removing object is also attracted to the intake port side and is brought into improper contact. This can be prevented. At the same time, dust adhering to the surface of the dust-removing object can be separated by the brush on the surface of the pressing roller by mechanical contact with the brush, and the static electricity charged on the dust-removing object can be removed. Can also be removed.
Therefore, it is possible to appropriately remove and collect dusts that are strongly attached to the dust removal target due to static electricity.

In the dust removing apparatus according to the present invention, the static electricity removing brush provided at the preceding stage of the intake port can remove the static electricity charged on the dust removing object. Therefore, similarly to the case of the seventh aspect, the dust can be efficiently removed.

In the dust removing apparatus according to the ninth aspect of the present invention, the case accommodating the air pulsation wave generating device and the filter is portable, and the flexible hose connected to the case sucks air. Since it is configured as a vacuum cleaner having a path formed, it is possible to remove and clean the floor surface and other desired positions by using a negative pressure air pulsating wave while moving the whole to an arbitrary place. it can.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment] FIG. 1 is a schematic perspective view showing an example of the entire structure of a dust removing apparatus A according to the present invention, FIG. 2 is a front view of a main part thereof, and FIG. 3 is an air constituting the dust removing apparatus A shown in FIG. FIG. 2 is a cross-sectional view illustrating an example of the pulsating wave generator 1. The dust removing device A is a device for removing dust from a paper sheet 90 which is fed and transferred from a winding roll R of a tape manufacturing device 80. The tape manufacturing apparatus 80 is, for example, as shown in FIG. 5, for cutting a wide winding roll R having a width L and manufacturing a plurality of winding tapes Ra having a smaller width. Specifically, in FIG. 1, the sheet 90 fed out and transferred from the winding roll R is cut by the disk-shaped cutter blades 91, 91 driven and rotated by the motor M <b> 1, and is continuous in the longitudinal direction of the sheet 90. Slit 9
2, 92 are formed. And the cut sheet 9
0 is wound as a plurality of winding tapes Ra. In such a process, the cutting of the sheet 90 generates dust as paper dust, which may adhere to the surface of the sheet 90. The dust removing device A according to the present embodiment is for removing such dust.

The components constituting the dust removing device A include an air pulsation wave generator 1, a pipe 30A connected to the air pulsation wave generation port 20a of the air pulsation wave generator 1, and a pipe 3A.
The air suction passage 3 formed in the inside of the air intake passage 3, the air inlet 30 formed to open at the front end side of the air suction passage 3, the filter 4 provided at the rear end of the air suction passage 3, and each device described later. I have it.

Of the above, the air pulsation wave generator 1 is for generating a negative pressure air pulsation wave.
And a pulsation imparting device 2 connected to the front side of the blower 5. Here, the pulsation imparting device 2
As shown in FIG. 3, a casing 20 in which an air pulsation wave generating port 20a is formed on the front end side and a blower connection port 20b is formed on the rear end side, and a substantially disk-shaped valve body disposed in the casing 20 21, a spacer 23 having a through hole 23 a serving as a valve seat of the valve element 21, a motor M for rotating the valve element 21 about the rotation shaft 22, and the like. The air suction side of the blower 5 is connected to the blower connection port 20b of the casing 20 via a pipe 30B, and the air in the casing 20 is blown by the blower 5.
So that it can be sucked in and exhausted to the outside.

The valve element 21 has a through-hole-shaped vent hole 21a.
The air in the casing 20 is sucked in by the blower 5 when the air confronts and coincides with the opening position b. Therefore, at that time, a negative pressure / suction force is generated at the air pulsation wave generation port 20a. On the other hand, when the valve body 21 rotates as shown in FIG. 4 and the vent hole 21a does not face the opening position of the blower connection port 20b,
As a result, the valve b is closed by the valve body 21 and the air suction from the inside of the casing 20 to the blower 5 is stopped.
At this time, no negative pressure / suction force is generated at the air pulsation wave generation port 20a. Therefore, the pulsation imparting device 2
In this case, the intermittent negative pressure / suction force is generated in the air pulsation wave generating port 20a by the continuous rotation of the valve body 21, and the air pulsation wave having a waveform as shown in FIG. it can.

The blower 5 connected to the pulsation imparting device 2 may be any blower capable of sucking the air in the casing 20 at a predetermined negative pressure. Therefore, in the present invention,
In addition to various blowers such as a ring blower and a roots blower, a vacuum pump and the like are also included in the concept of the blower. Also,
The blower 5 may be operated continuously.
In this case, for example, as shown in FIG.
When 0b is closed, it is the same as when the pipe 30B is clogged, but the time is short, so that the operation of the blower 5 is not hindered.
On the contrary, in this state, since the pressure in the pipe 30B can be reduced, the vibration pressure (amplitude) of the air pulsation wave can be reduced.
Can be increased, and a favorable result is obtained.

In FIG. 1, the air suction path 3 is connected to the air pulsation wave generation port 20a of the air pulsation wave generation device 1 described above. Accordingly, at the intake port 30 of the air suction path 3, a negative pressure air pulsation wave is also generated by the operation of the air pulsation wave generation device 1, and intermittent air suction is performed. The width of the intake port 30 is set so that dust can be removed from the entire surface of the sheet 90.
The width of the sheet 90 is equal to or larger than the width of the sheet 90, and is disposed above the transfer position of the sheet 90. In addition, the set height of the intake port 30 is designed to be arbitrarily adjustable. The filter 4 is for collecting dust and has air permeability so as not to hinder the air flow in the air suction passage 3. The filter 4 is designed so that it can be easily attached to and detached from the pipe 30A so that the filter 4 can be appropriately replaced when clogging occurs.

In this embodiment, two pipes 6a and 6b are arranged at the left and right sides of the intake port 30. A large number of small-diameter exhaust holes 7 are drilled at a constant pitch on the lower surface side of each of the pipes 6a and 6b, and compressed air supplied from a blower 5A provided separately from the blower 5 discharges the exhaust gas. It is configured such that air is continuously or intermittently exhausted from the holes 7 to the surface of the sheet 90.

Since the dust removing apparatus A according to the present embodiment has the above configuration, the cutter blade 91 of the tape manufacturing apparatus 80,
When the sheet 90 is cut at 91, even if paper dust of the sheet 90 is generated as dust, these dusts
Thus, dust on the surface of the sheet 90 can be removed. Further, dust sucked into the air suction path 3 is collected by the filter 4 and can be appropriately disposed. Thus, at the intake port 30, not only intake is performed but also air pulsation wave of negative pressure (for example, 10H).
This is a state in which a pulsating wave in a low / middle frequency range of about z is generated. Therefore, the surface of the position of the sheet 90 facing the intake port 30 (region C in FIG. 2) vibrates, and a phenomenon of separation of dust adhering to the sheet 90 occurs. As a result, dust that could not be removed only by continuous simple air suction can be appropriately removed and recovered.

The suction force of the suction port 30 also acts on the sheet 90. The sheet 90 is pushed downward by compressed air exhausted from pipes 6a and 6b disposed on both left and right sides of the suction port 30. Therefore, the seat 90 is not unduly sucked into the intake port 30. Also, by blowing compressed air onto the sheet 90 from the pipes 6a and 6b, dust adhered to the surface of the sheet 90 can be separated or released, and the cleaning of the sheet 90 is promoted. The Rukoto.

[Second Embodiment] FIG. 7 is an explanatory view showing another embodiment of a dust remover Aa according to the present invention. This dust removing device Aa has the same basic configuration as that of the first embodiment, but a pressing roller 8 is provided inside an intake port 30 in place of the pipes 6a and 6b of the first embodiment. And a static electricity removing brush 9 is provided at a position on the preceding stage of FIG. The pressing roller 8 is supported by the holder 11 attached to the bracket 10 inside the pipe 30A.
An elastic spring 12 is interposed in the holder 11. With such a configuration, the pressing roller 8 is provided so as to contact the sheet 90 with an appropriate pressing force.
A brush 13 made of an organic conductive fiber or the like and having a static electricity removing function is provided on the outer peripheral surface of the pressing roller 8. The static elimination brush 9 has the same static elimination function as the brush 13 of the pressing roller 8, and is provided such that a tip portion thereof contacts the surface of the sheet 90. The static electricity removing brush 9 is designed so that its height can be adjusted freely.

In the dust removing apparatus Aa having the above structure, the intake port 30
Even if a suction force is generated in the sheet 90, the sheet 90 is kept
The rise of the sheet 90 is also prevented, so that the sheet 90 is also prevented from being unduly sucked into the intake port 30. On the other hand, when removing dust, first, the static electricity removing brush 9 is in contact with the surface of the sheet 90, so that the static electricity charged on the sheet 90 is removed.
When the sheet 90 is transported or the like, static electricity is easily charged, and dust may be strongly adhered by the action of the static electricity. However, if the static electricity is removed, dust can be easily removed. . The removal of such static electricity is further thorough by the brush 13 of the pressing roller 8 having a static electricity removing function. Therefore, at the position of the intake port 30, dust such as paper dust can be efficiently removed and collected by the negative pressure air pulsation wave without static electricity. Further, since the static electricity removing brush 9 is in contact with the sheet 90, the mechanical contact of the brush also causes the dust adhering to the surface of the sheet 90 to be forcibly peeled off. The efficiency will be better.

In the above configuration, static electricity is removed by both the brush 13 of the pressing roller 8 and the static electricity removing brush 9, but the present invention is not limited to this. When the static electricity removing brush 9 is provided, a simple roller without the brush 13 may be used instead of the pressing roller 8 with the brush 13. Conversely, when the pressing roller 8 having the brush 13 is used, the static electricity removing brush 9 may be removed. However, in this case, FIG.
As shown in (2), it is preferable to dispose the pressing roller 8 in front of the intake port 30 and increase the opening area (corresponding to the dimension L1) behind the pressing roller 8, because the dust removal efficiency can be improved.

[Third Embodiment] FIG. 9 is an overall explanatory view showing another embodiment of the dust removing device Ab according to the present invention. This dust removal device Ab is different from the pulsation imparting device 2 for generating a negative pressure air pulsation as the air pulsation wave generation device 1A.
A pulsation imparting device 2A for generating positive pressure air pulsation is additionally provided separately. The positive pressure air pulsation wave generated by the pulsation imparting device 2A is configured to be guided to the position of the exhaust port 31 provided inside the intake port 30 via the pipe 30c.

In such a configuration, the sheet 9 is
A positive pressure air pulsation wave is transmitted with respect to 0, and a negative pressure air pulsation wave is generated from the intake port 30 opened around the exhaust port 31. Therefore, in removing dust from the surface of the sheet 90, not only air pulsation due to negative pressure but also air pulsation at positive pressure is added, and the amplitude of vibration applied to the sheet 90 is doubled. As a result, the effect of removing dust by air vibration becomes even better,
The dust removal efficiency will increase. In addition, since the air exhausted from the exhaust port 31 is efficiently sucked from the intake port 30, it is possible to eliminate the possibility that dusts scatter around the intake port 30 due to the influence of the positive pressure air pulsation wave. Is possible. Note that the exhaust port 31 does not necessarily need to be arranged inside the intake port 30. Even if the exhaust port 31 is arranged outside the intake port 30, the same effect as described above can be obtained.

As the above air pulsation wave generator 1A,
For example, as shown in FIG. 10, the configuration may include a pulsation imparting device 2A. That is, the pulsation imparting device 2A
The other pulsation imparting device 2 has the same basic configuration as the other negative pressure pulsation imparting device 2 in that the blower connection port 20b 'of the casing 20' is connected to the air discharge port 5b side of the blower 5. It is only substantially different from 2. In the pulsation imparting device 2A, the vent hole 21a 'of the valve body 21' is provided.
When air flows in communication with the blower connection port 20b ', air is supplied from the blower 5 into the casing 20', and air is discharged from the air pulsation wave generation port 20a '. On the other hand, the valve element 21 'is connected to the blower connection port 20.
When b 'is rotated to the position to close it, the casing 2
No air is supplied to the inside of the air pulsating wave generating port 20 '.
Air discharge from a 'is stopped. Therefore, the valve element 21 '
Is continuously rotated, so that the air pulsation wave generation port 20
A positive air pulsation wave can be generated by performing intermittent air discharge from a ′.

If the rotary shafts 22 and 22 'of the two pulsation imparting devices 2 and 2A are connected to each other, the two pulsation imparting devices 2 and 2A can be operated by one motor M, which is reasonable. It is. Further, the blower 5 is connected to the pulsation imparting devices 2 and 2A.
It is preferable to connect them to both of them, since the overall device configuration can be further simplified. However, in the present invention, such a configuration is not always a requirement. For example, a device for generating a positive pressure air pulsation is completely different from an air pulsation wave generating device for generating a negative pressure air pulsation wave. Alternatively, it may be provided.

Fourth Embodiment FIG. 11 is a partially cutaway sectional view showing an example of a case where a dust removing device Ac according to the present invention is configured as a vacuum cleaner. The dust eliminator Ac reduces the size of the air pulsation wave generator 1 composed of the blower 5 and the pulsation imparting device 2 shown in FIG. 3 and places it in a portable case 41 made of a synthetic resin or the like having a caster 40. It was housed. The air suction path 3 connected to the air pulsation wave generation port 20a via the filter 4 is formed by a flexible hose 30D connected to the outside of the case 41. The filter 4 is designed and modified as needed, for example, so as to collect and accommodate a large amount of dust. In such a vacuum cleaner type dust remover Ac, when cleaning the floor or the like at home or the like,
The dust adhered to the floor or the like can be sucked and collected after being separated by the air pulsating wave, and excellent cleaning can be performed. In addition, the rotation of the valve body 21 is stopped,
If the air hole 21a is kept in communication with the blower connection port 20b, no air pulsation wave is generated, and a mere continuous suction is performed from the suction port 30 as in a normal vacuum cleaner. Is possible.

[Other Embodiments] FIG. 12 is an explanatory view showing another embodiment of the air pulsation wave generator 1B. The air pulsation wave generator 1B includes an air pulsation wave generation port 20a on an outer peripheral wall portion 24 of a cylindrical casing 20A.
And a blower connection port 20b. Further, the valve body 21A rotates about the rotation shaft 22A so as to maintain a state in which the interior of the casing 20A is partitioned into two space chambers 25A and 25B. In such a configuration, when the air in the casing 20A is sucked by the blower 5, the outside air can be sucked from the air pulsation wave generating port 20a when the valve body 21A is at the position shown by the one-dot chain line in FIG. On the other hand, when rotating to the position shown by the solid line in the figure, outside air cannot be taken in from the air pulsation wave generation port 20a. Therefore, even with the device having the above-described configuration, a negative-pressure air pulsation wave can be appropriately exerted. In the present invention, such a type of air pulsation wave generator can be applied.

In the first to third embodiments of the above-described embodiments, the sheet 90 is described as an example of a dust-removing object. It is also effective when the material is a dust removal target. In addition, the specific articles, materials, parts, and the like to be dust-removed are not limited at all.

[0043]

As will be understood from the above description, according to the dust removing apparatus according to the present invention as set forth in claims 1 to 9, the surface of the dust removing target is vibrated by the pulsating wave of the negative pressure air. Since the adhered dust can be separated and the separated dust can be appropriately sucked and collected by the negative pressure, the dust that cannot be removed by the conventional simple continuous air suction alone can be removed. The effect is obtained that the dust can be removed properly and the dust can be efficiently removed and collected without being scattered around.

Further, since a negative pressure air pulsation wave can be generated by using a blower, the vibration pressure of the air pulsation wave can be easily increased by increasing the suction / exhaust pressure of the blower. An advantage is obtained in that the dust separating action can be promoted by the high-pressure air pulsating wave.

In particular, according to the second aspect of the present invention, the dust collected in the air suction path can be appropriately collected by a predetermined filter, so that the dust is directed to the air pulsation wave generator side. It is possible to protect these devices by preventing intrusion, and to provide an advantage that disposal of dust collected by the filter can be conveniently performed.

According to the third aspect of the present invention, in order to generate a pulsation wave by rotating a valve body in a predetermined casing connected to a blower, a pulsation imparting device can be manufactured in a small size. The advantage that the mechanical vibration and noise of such a device can be suppressed can be obtained.

According to the present invention, in addition to the dust separating action by the negative pressure air pulsating wave, the dust separating action by the positive pressure air pulsating wave is synergistically obtained.
The effect that a more excellent dust removal operation can be performed is obtained.

According to the fifth and sixth aspects of the present invention, when removing and collecting dust adhered to a sheet-like or panel-like dust-removing object, the dust-removing object is sucked to the suction port side. This has the advantage that it is possible to properly avoid contact with and damage to the air inlet.

According to the seventh aspect of the present invention, it is possible to prevent the dust-removing object from being attracted to the intake port side and coming into contact with the unreasonable one by the pressing roller, and adhere to the surface of the dust-removing object. Dust can be peeled off by mechanical contact with the brush, and static electricity charged on the dust removal target can be removed. Therefore, even if the dust is strongly attached to the dust removal target due to the action of static electricity or the like, the effect of appropriately removing and collecting the dust can be obtained.

According to the present invention, since the static electricity charged on the object to be dust-removed can be removed by the static electricity removing brush, the effect of removing the dust efficiently can be obtained.

According to the ninth aspect of the present invention, since the vacuum cleaners are configured as vacuum cleaners, they can be entirely moved to an arbitrary location while removing dust and dust from the floor and other desired positions.
The advantage that the cleaning can be performed efficiently and appropriately can be obtained.
