Description

  The present invention relates to a polishing machine with a suction function that is used to suppress the generation of dust that occurs during the polishing of putty at the place where gypsum boards are joined in interior construction of a building.

  When cross-finishing or paint-finishing the interior of a building, after installing gypsum board as the foundation, to fill the joints between the gypsum boards and screw holes created when fixing the gypsum board to the base rail with screws Then, putty is put on the plasterboard surface.

  After the putty has dried, an operation to polish the extra putty is performed to eliminate unevenness of the gypsum board surface. In this putty polishing operation, excess putty is scraped off with a paper file or the like, but a handy type electric polishing machine (hand-held operation sander) 21 is used for polishing the putty as shown in FIG.

  However, during the putty polishing operation, the dust of the polished putty rises and the periphery is soiled with the putty dust, which adversely affects other types of work. There is also a risk of pneumoconiosis, which may adversely affect the eyes, ears, respiratory organs, etc. Wearing protective equipment such as a mask and goggles is essential.

  Furthermore, after the work was completed, cleaning to remove putty dust had to be performed. Therefore, curing is necessary.

  Further, since the handy type electric polishing machine 21 does not reach the wall or ceiling portion having a height of 2 M or more, a standing horse or a portable work table 23 is installed and used. At that time, an accident such as dropping may occur.

  Therefore, the worker was cleaning the dust by sucking it with a vacuum cleaner or the like.

  However, the dust generated by such interior construction is mainly putty powder produced by wrinkling and polishing the convex part of the putty applied to the base wall, and a large amount of fine powder with a particle size of about 5 to 30 μm is generated. For this reason, recently, in order to efficiently collect such a large amount of fine dust, an electric dust collector that sucks up dust at the same time is being used.

Although the electric dust collector is also disclosed in the following patent document, for example, as shown in FIG. 8, a handy type electric polishing machine 21 is gripped by a cover member 26 that covers the periphery of the sander with the surface of the sander 22 exposed. 25, the suction port 28 at the top of the cover member and the portable electric dust collector 20 are connected by a hose 29, so that the dust generated on the surface is kept inside the cover member without dropping. It is a dust collection sander that sucks dust from the inside of the cover member by suction by the dust collector 20.

  Since the dust collection sander (hand-held type electric polishing machine 21) of Patent Document 1 does not reach the wall or ceiling part having a height of 2M or more, a standing horse or a portable work table 23 must be used.

  Further, it is a vibration type dust collecting sander, which is used by adjusting the degree of pressing to some extent with the grip portion 25, and it is difficult to adjust the force.

  The purpose of the present invention is to eliminate the inconveniences of the conventional example, have a dust collection performance, obtain a good finish, and reach walls and ceilings with a height of 2M or more. There is a need to provide a polishing machine that can.

  In order to achieve the above object, the present invention according to claim 1 comprises a dust collector body, a suction hose connected to the dust collector, an extension pipe as a handle, and a rotating part / suction part provided at the tip thereof. A disc sander in which an abrasive member is stacked on a rubber pad is attached to the portion, and the abrasive pad is used to polish a ceiling surface or a wall surface as the rotating portion rotates, and the rubber pad of the disc sander is a thick donut. The gist is that it is formed of a disc-shaped sponge.

  According to the first aspect of the present invention, the dust collector main body, the suction hose connected to the dust collector main body, and the extension pipe serving as a handle are provided. Therefore, by holding the extension pipe serving as a handle, a wall or ceiling having a height of 2M or more Work can be done by reaching the part, no standing horse or portable worktable is required, and there is no risk of falling.

  In addition, the polishing member is a polishing machine that polishes the ceiling surface or wall surface with the rotation of the rotating part, but the rubber pad of the disk sander is formed of a thick donut disk-shaped sponge, so that the hard rubber Thus, it can be pressed with moderate softness without being too hard, and the polishing finish is also good.

  The gist of the present invention described in claim 2 is that the disc sander is formed by attaching an abrasive member to a rubber pad, and the abrasive member is disk-shaped with respect to the rubber pad, and its outer periphery projects.

  According to the second aspect of the present invention, the disc sander is an integrated type in which an abrasive member is attached to a rubber pad, and the abrasive member is firmly supported by the rubber pad and the outer periphery thereof protrudes. Thus, the gap between the hood opening surfaces of the rotating part and the suction part can be reduced, and the efficient suction of dust can be maintained.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the entire polishing machine of the present invention will be described. As shown in FIG. 5, a dust collector main body 1, a suction hose 2 connected to the dust collector main body 1, an extension pipe 3 serving as a handle, and a rotating part / suction part 4 provided at the tip thereof. It consists of.

  The dust collector main body 1 is a vertical drum type and is movable with a caster 1a provided at the bottom.

  The suction hose 2 is a flexible tube, and the extension tube 3 is a hard tube. The extension tube 3 can be expanded or contracted.

  The rotary part / suction part 4 has a rotary drive shaft 6 at the center of a disc-shaped hood 5 in which a distal end of the extension pipe 3 or a flexible pipe 14 connected to the extension pipe 3 is opened. A disk sander 7 is formed on the rotary drive shaft 6. The rubber pad 8 and the sandpaper 9 as an abrasive member are fixed in a state where they are overlapped. In the figure, 10 is a support plate on the rotary drive shaft 6 side, and 11 is a holding screw.

  As shown in FIG. 2, the rubber pad 8 has a thick donut disk shape. Sponge was used to form a circular hole 8a in the center.

  The sandpaper 9 is also a thin disk shape and has a circular hole 9a at the center. The rubber pad 8 and the sandpaper 9 are integrated by pasting, and the sandpaper 9 is attached to the rubber pad 8. The outer periphery 9b protrudes.

  The circular hole 9a at the center of the sandpaper 9 is larger than the circular hole 8a at the center of the rubber pad 8, and the peripheral portion of the circular hole 8a at the center of the rubber pad 8 is exposed from the hole 9a. The head of the holding screw 11 comes into contact with this portion.

  The disk sander 7 is fitted in the disk-shaped hood 5 of the rotating part / suction part 4 by being fastened to the rotating drive shaft 6 with a screw 11 and is rotationally driven by the rotating part / suction part 4 as shown in FIG. A mechanism 12 is provided, whereby the disk sander 7 rotates in the rotating unit / suction unit 4. In the figure, reference numeral 13 denotes a gripping / operating unit provided on the extension pipe 3.

  Next, the usage will be described. During the putty polishing operation, most of the dust of the putty that has been polished is collected in the dust collector body 1 and does not leak outside. Moreover, as shown in FIG. 6, it can reach a wall or a ceiling part by the extension pipe 3, and it does not need a work table etc.

  When the sandpaper 9 is applied, the rubber pad 8 acts as a cushioning material and is not too hard, and a satisfactory finish can be obtained.
