Description

The present invention relates to a device for a dust collecting sander device that collects dust generated by polishing work for adjusting the base surface by a sander when constructing an interior such as a ceiling surface or a wall surface by a suction means.

In the interior construction of a building such as a house, for example, a large amount of dust is generated by the work of filing the base surface for adjusting the base before applying the wallpaper to the ceiling surface or the wall surface. Therefore, the worker sucked up the dust with an electric vacuum cleaner or the like to clean it.

However, the dust generated in such interior construction is mainly putty powder generated by shaving the convex portion of the putty applied to the base wall surface, and a large amount of fine powder having a particle size of about 5 to 30 μm is generated. Therefore, in recent years, in order to efficiently collect such a large amount of fine dust, for example, a dedicated electric dust collector capable of interlocking work by connecting a sander has been used (for example, patent documents). See 1.).

On the other hand, such an electric dust collector and a dust collecting sander can obtain a dust collecting sander capable of collecting dust more efficiently than the conventional one without deteriorating the workability of the polishing operation as compared with the conventional one. However, it is difficult for workers to handle it because it is necessary to equip an electric dust collector, a dust collector sander, a battery, a power supply means such as a 100V power supply and a power cable, and a dust collection hose for connecting the dust collector and the sander at the same time. It was a thing. Therefore, the applicant has proposed a dust collecting sander device that is easy to handle (see Patent Document 2).

Japanese Unexamined Patent Publication No. 2001-62725 Utility Model Registration No. 3209519

Since the proposed dust collector sander device has a built-in battery in the handle, the center of gravity of the dust collector sander device does not change much even when working on the wall or ceiling, so the operator manually handles the sander device. It has an excellent effect of facilitating. However, since the cover member is arranged so as to cover the file surface and the dust collecting means communicating with the inside of the cover member creates a negative pressure state, the dust collecting sander device itself is sucked into the work surface such as the interior wall, and the work is performed.

According to the present invention, it is possible to obtain a dust collecting sander device in which the dust collecting sander device itself is difficult to be sucked into a work surface such as an interior wall, and dust can be sucked well without burdening the operator. effective.

It is explanatory drawing which shows the structure of one Example of the dust collecting sander apparatus of this invention, a figure is a plan view, and b figure is a left side view. It is explanatory drawing which shows the structure of the main part of FIG. 1, a figure is a cross-sectional view of AA including a part enlarged view which shows the state which a sandpaper is attached, b figure is a bottom view, and c figure is sandpaper. It is a BB cross-sectional view which shows the state which affixed. It is explanatory drawing which shows the structure of the main part of FIG. 1, a figure is a right side view which shows the state which a sandpaper is stuck, b figure is a front view which shows the state which a sandpaper is stuck, and c figure is a sandpaper. It is a rear view which shows the state which attached.

In the present invention, a hand-held sander portion that exposes the filed surface and detachably locks the mesh sandpaper for polishing the surface to be polished, and dust generated by polishing the surface to be polished by the hand-held sander portion. It is a dust collecting sander device provided with a dust collecting means for sucking. As the file surface of the present invention, sandpaper attached to the support plate is used, and dust is collected on the back surface side of the sandpaper. For this reason, it is conceivable to attach a sandpaper having holes through which a large number of dusts pass, but the base material to which the abrasive grains are attached is allowed to pass the dust generated by polishing with the sandpaper surface to the back surface side. A mesh sandpaper with a mesh structure that can be formed is optimal.

The dust collecting means of the present invention includes a cover member that covers the central portion and the peripheral portion from the back surface side of the mesh sand paper with the surface of the hand-held sander exposed, and a motor portion installed on the cover member. And, the fan part rotated by this motor part and the dust in the cover member are removed from the suction passage which is installed in the cover member so as to surround the fan part and creates a negative pressure by the rotation of the fan part and communicates in the cover member. It is provided with a suction chamber for sucking the containing air and a discharge port for discharging the air containing the dust sucked in the suction chamber. As a result, the electric dust collector and the dust collector sander are not separated but integrated, so that the operator can easily handle the dust collector.

As the hand-held sander portion of the present invention, the filed surface of the mesh sandpaper for polishing the surface to be polished is exposed, and the sanded surface may be used for polishing. The file surface may be manually brought into contact with the surface to be polished for polishing, and if possible, the surface to be polished may be polished with an electrically driven file surface.

In such a dust collecting sander device of the present invention, as a configuration of the hand-held sander portion, a support plate that supports the back surface of the central portion of the mesh sandpaper that is detachably locked and a file surface formed on the support plate. It may have a structure including one or more suction ports communicating with the suction port of the suction chamber from the side.

The cover member of the present invention may cover the central portion and the peripheral portion from the back surface side of the mesh sandpaper with the file surface of the hand-held sander portion exposed, and does not interfere with the polishing work. The rotation of the fan portion may be used as long as it sucks the surrounding air and sucks the dust generated by polishing into the suction chamber. Further, the hakama portion provided as the peripheral wall of the cover member covering the peripheral portion of the file surface is formed of a flexible material, and the tip portion of the hakama portion that abuts on the back surface of the peripheral portion of the mesh sandpaper is supported. It is a height position equivalent to the exposed height position of the board.

As a result, while polishing the object to be polished on the file surface of the mesh sandpaper, the surrounding air is sucked through the mesh sandpaper and the slight gap between the mesh sandpaper and the skirt, and the dust generated by the polishing is sucked. be able to. Therefore, the dust collecting sander device itself is not sucked into the work surface such as the interior wall, and has an advantage that the dust can be sucked well without burdening the operator.

As the mesh sandpaper used in the dust collecting sander device of the present invention, sandpaper in which abrasive grains are attached to a mesh-like base material, which is already commercially available, can be used. The size of the mesh sandpaper may be a size that can cover the entire circumference of the hakama portion of the cover member of the dust collecting sander device of the present invention. The roughness of the sandpaper may be coarse to fine, and may be, for example, # 40 to # 280, more preferably # 80 to # 120.

The skirt portion of the cover member is, for example, a polyolefin resin such as a polystyrene-based elastomer, a polyethylene resin (PE), a polyethylene vinegar resin (EVA), a polypropylene resin (PP), a polyolefin-based elastomer, or a polyethylene terephthalate resin (PET). ), Polybutylene terephthalate resin (PBT), polyethylene naphthalate resin (PEN) and other polyester resins, polymethyl methacrylate resin (PMMA), polyacrylonitrile resin, ABS resin and other polyamide resins, polystyrene resins (PS) ), Polyvinyl chloride resin (PVC), Polyvinylidene chloride resin (PVDC), Polycarbonate resin (PC), Polyacetal resin, Polysulfone resin, Natural rubber (NR), Chloroprene rubber (CR), Ethylene / propylene rubber, Chloroprene rubber ( If it is made of a relatively soft material such as CR), ethylene / propylene rubber (EPDM), styrene / butadiene rubber (SBR), butyl rubber (IIR), acrylonitrile rubber (NBR), urethane rubber, fluorine rubber, silicon rubber, etc. Good.

Further, when the support plate is made of a material having cushioning property or elasticity, it is possible to obtain a good polishing result on the surface to be polished by the operator in the polishing work on the surface to be polished. Therefore, for example, as the material of the support plate, foamed ethylene / propylene rubber (EPDM), foamed natural rubber (NR), foamed chloroprene rubber (CR), foamed ethylene / propylene rubber (EPDM), foamed acrylonitrile rubber (NBR), etc. Foamed silicon rubber, foamed fluorine rubber and the like can be used.

It is important for polishing workability that the repulsion due to contact with the polishing surface during polishing does not differ significantly between the tip of the hakama and the support plate, depending on the material of the cover member and the material of the support plate. Become. That is, if the hakama portion is extremely soft with respect to the polishing work of the support plate, the hakama portion is likely to break inward during the polishing work. Therefore, the workability is improved when the hakama part is made of a material having high resilience. By the way, the hakama portion has an overwhelmingly small installation area on the polished surface with respect to the support plate. For this reason, the height position of the tip of the hakama portion of the cover member and the exposed height position of the support plate are set to the same height position, but even when a highly repulsive material is used, the support plate With respect to the exposed height position, extend the height position of the tip of the hakama part of the cover member by about 0.1 to 1.0 mm and adjust it so that it first contacts the back surface of the mesh sandpaper to make the hakama part. It may have resilience.

In a preferred embodiment of the present invention, the hakama portion of the cover member that supports the back surface side of the peripheral edge portion of the mesh sandpaper is inclined outward from the circumference. As a result, even when the file surface is brought into contact with the surface to be polished to perform polishing work, the hakama portion does not break inside the circumference, and a large gap is formed between the mesh sandpaper and the tip portion of the hakama portion. There will be no such thing.

Another preferred embodiment of the present invention includes a battery for driving the motor portion built in the handle portion of the handheld sander portion. As a result, by incorporating a relatively heavy battery in the handle that the operator holds, the center of gravity of the sander device does not change much even when working on the wall or ceiling, so the operator can handle the sander device. It will be easy. Therefore, the polishing work can be easily performed.

FIG. 1 is an explanatory view showing a configuration of an embodiment of the dust collecting sander device of the present invention, where a is a plan view and b is a left side view. FIG. 2 is an explanatory view showing the configuration of a main part of FIG. 1, FIG. 2A is a sectional view taken along the line AA including a partially enlarged view showing a state in which sandpaper is attached, and FIG. 2B is a bottom view and a view c. Is a cross-sectional view taken along the line BB showing a state in which sandpaper is attached. 3A and 3B are explanatory views showing the configuration of the main part of FIG. 1, FIG. 3A is a right side view showing a state in which sandpaper is attached, FIG. 3B is a front view showing a state in which sandpaper is attached, and FIG. Is a rear view showing a state in which sandpaper is attached.

As shown in each figure, the dust collecting sander device 10 of this embodiment is provided with a support plate 11 on one side to which the file surface is exposed and the mesh sandpaper 16 is attached, and a handle portion 12 is provided on the other side. A hand-held sander portion 13 and a dust collecting means 20 for sucking dust generated by polishing the surface to be polished by the hand-held sander portion 13 are provided.

Specifically, the hand-held sander portion 13 is composed of the support plate 11 to which the mesh sandpaper 16 is attached and the handle portion 12 connected to the support plate 11. The support plate 11 on which a large number of suction ports 25 are formed has a hook surface that is raised in a hook shape for locking and holding the loop surface that is densely raised in a loop shape on the back surface of the mesh sandpaper 16. The exposed hook-and-loop fastener hook material 17 is attached. The material of the support plate 11 of this embodiment is foamed ethylene propylene rubber (EPDM), and good polishing work by an operator can be obtained from this cushioning property.

The dust collecting means 20 includes a cover member 21 that covers the central portion and the peripheral portion of the mesh sand paper 16 from the surface side in a state where the threaded surface of the hand-held sander portion 13 is exposed, and the handle portion 12 of the cover member 21. A negative pressure is created by rotating the motor unit 23 installed at the rear end portion, the fan unit 24 rotated by the motor unit 23, and the fan unit 24 installed on the cover member 21 so as to surround the fan unit 24. Air containing dust in the cover member 21 is introduced from a large number of suction ports 25 bored in the support plate 11 in the cover member 21 through a suction passage formed between the support plate 11 and the inside of the cover member 21. A suction chamber 26 for suction, a discharge port 27 for discharging air containing dust sucked in the suction chamber 26, and a dust collection bag 19 having an opening end connected to the discharge port 27 via a communication jig 35. Be prepared.

The suction chamber 26 of the dust collecting sander device 10 of this embodiment has a cylindrical internal shape that holds the motor portion 23 and the fan portion 24 inside. The motor unit 23 is mounted in the cylinder of the cylindrical fan unit 24, and the four-blade fan unit 24 is rotated by driving the motor unit 23. The rotation of the four blades causes an air flow away from the support plate 11 along the rotation axis, and air is discharged into the dust collection bag 19 from the discharge port 27 formed on the cylindrical side surface of the suction chamber 26. The inside of the suction chamber 26 is negative pressure.

A large number of round hole-shaped suction ports 25 formed in the support plate 11 penetrate the support plate 11 and are bored on the lower surface side of the cover member 21. Specifically, the suction port 25 is formed on the lower surface of the passage forming plate 28 which is arranged in the central region of the support plate 11 and is connected by projecting the cover member 21 upward around the grip portion of the cover member 21. It is connected to the suction passage.

The mesh sandpaper 16 bonded to the hook-and-loop fastener hook material 17 of the support plate 11 is a breathable base material having a back surface in which the bonded surface is raised in a loop shape, and passes through the base material to collect dust. The contained air is sucked into the suction port 25 having a round hole that is not blocked by the hook-and-loop fastener hook material 17. The air containing dust sucked from the suction ports 25 of a large number of round holes from the inside of the cover member 21 merges in the suction passage formed by the passage forming plate 28 and the support plate 11 in the central portion, and becomes a negative pressure. It is sucked into the suction chamber 26.

Further, the cover member 21 covers the central portion and the peripheral portion of the mesh sandpaper 16 with the file surface of the mesh sandpaper 16 locked and held by the support plate 11 of the hand-held sander portion 13 exposed. It suffices as long as it does not interfere with the polishing work, and the rotation of the fan portion 24 sucks the surrounding air and also sucks the dust generated by the polishing into the suction chamber 26.

Further, the hakama portion 22 as the peripheral wall of the cover member 21 that supports the back surface side of the peripheral edge portion of the mesh sandpaper 16 is made of a flexible polystyrene elastomer, and as shown in FIG. 2A, the hakama portion 22 The height position of the tip portion of the support plate 11 is the same height position as the exposed height position of the support plate 11. As a result, while polishing the sandpaper surface on the sandpaper surface of the mesh sandpaper 16, dust generated by polishing while sucking the surrounding air through the mesh sandpaper 16 and a slight gap between the mesh sandpaper 16 and the skirt portion 22 Can be sucked. Therefore, the dust collecting sander device itself is less likely to be sucked into the work surface such as the interior wall, and has an advantage that the dust can be sucked satisfactorily without burdening the operator. The height position of the tip of the hakama portion 22 is extended 0.5 mm ahead of the exposed height position of the support plate 11 so as to come into contact with the back surface of the mesh sandpaper 16 first.

The hakama portion 22 arranged over the entire circumference is arranged so as to be inclined outward from the circumference. As a result, the hakama portion 22 does not break inward of the circumference even when the mesh sandpaper 16 locked and held by the support plate 11 on the surface to be polished is used for polishing, and the mesh sandpaper 16 and the hakama portion 22 are not broken. It is possible to maintain a good suction effect without forming a large gap with the tip of the hakama.

The suction chamber 26 is provided with a saucer portion 29 having an opening having a diameter smaller than the diameter of the four blades of the fan portion 24. The opening of the saucer portion 29 serves as the entrance of the suction chamber 26. A snowdrift chamber 30 is formed on the outer circumference of the saucer portion 29 over the entire circumference. In this embodiment, the snowdrift chamber 30 is divided into three sections, and an opening 31 penetrating the saucer portion 29 is formed on the bottom surface of each of the divided sections.

The snowdrift chamber 30 functions as a room for temporarily collecting the polished dust inside the dust collecting bag 19 in order to prevent the backflow of the dust when the dust has accumulated in excess of the permissible amount. That is, in a situation where the dust collected in the dust collecting bag 19 exceeds the permissible amount and loses its place in the situation where the dust collected in the dust collecting bag 19 is sucked by the fan portion 24 of four blades and sent to the dust collecting bag 19, the air containing the dust is a fan. It falls along the outer circumference of the four blades of the portion and reaches the periphery of the opening of the saucer portion 29.

Since the four blades continue to rotate, the air containing dust that has reached the vicinity of the opening of the saucer portion 29 flows into the snowdrift chamber 30 through the gap at the lower end on the central portion side of the snowdrift chamber 30. In the snowdrift chamber 30, the air containing dust directed outward along the surface of the saucer portion 29 hits the side wall of the suction chamber and is changed in direction upward, and further, the direction is directed toward the ceiling portion and the inner side wall of the snowdrift chamber 30. Can be changed. Therefore, the dust rotated together with the air falls into the snowdrift chamber 30, and a part of the dust falls from the opening 31 to the upper surface of the support plate 11.

At this stage, the polished dust falls from the device, and the operator confirms that it is abnormal. Stop the work, remove the dust collection bag 19, and dispose of the dust inside. Can be done.

In the dust collecting sander device 10 of this embodiment, a battery for driving the motor unit 23 is built in the handle portion 12 of the handheld sander portion 13. That is, a handle cover 14 is detachably attached to the handle portion 12, and a battery holder 15 capable of holding a dry battery is arranged inside the handle cover 14. By mounting the battery in the battery holder 15 and mounting the handle cover 14, a relatively heavy battery is built in the handle portion 12 held by the operator, so that the work of the wall portion and the ceiling portion can also be collected. Since the change in the center of gravity of the dust sander device 10 is small, the operator can easily handle the dust collecting sander device 10. Therefore, the polishing work can be easily performed.

The battery can be held inside the handle portion 12 without being attached to the battery holder 15, and may be a rechargeable battery that follows the shape of the handle portion 12 instead of being cylindrical. As a result, even in the work of the wall portion and the ceiling portion, the change in the center of gravity of the dust collecting sander device 10 is small, so that the operator can easily handle the dust collecting sander device 10.

Further, a dust collecting bag 19 for filtering dust is attached to the discharge port 27 for discharging air containing dust sucked in the suction chamber 26 via a communication jig 35. That is, one end of the communication jig 35 is fixed to the opening of the dust collecting bag 19 that collects dust from the air containing dust that is attached to the discharge port 27, and the other end is attached to the discharge port 27. The communication jig 35 and the discharge port 27 are rotatably fixed by a C-shaped hook 40. The communication jig 35 is bent in a "<" shape.
