Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a polishing device, and more particularly, to a two-roll type polishing device having good operability.

[0002]

[Prior Art]

 There are two types of conventional polishing equipment, one with a roll shape and the other with a disk shape for the polishing part that is rotated by the prime mover. The material of the material can be changed. 4 and 5 are views showing an example of a conventional polishing apparatus in which a polishing portion has a roll shape. FIG. 4 is a side view and FIG. 5 is a plan view. The conventional technique will be described below with reference to the drawings. That is, the electric motor 2 is housed in the case 1, and the first gear 4 is provided on the extension of the rotary shaft 3 of the electric motor 2. A roll-shaped polishing section 5 is housed in the case 1, and a second gear 7 is provided on an extension of the rotary shaft 6 of the polishing section 5. The rotational force of the first gear 4 rotated by the rotation of the electric motor 2 is transmitted to the second gear 7 via the intermediate gear 8, whereby the polishing section 5 is rotated at high speed. The above-described first and second gears 4 and 7 intermediate gear 8 have a deceleration function of decelerating the rotation speed of the electric motor 2 and transmitting it to the polishing section 5. Both of these gears are provided in the gear box 9. It is stored, and the lid 10 is opened and closed to perform maintenance and inspection of each gear and the like, and the gears are replaced to change the reduction ratio.

In the polishing apparatus having the above structure, the two grips 11 and 11 ′ are grasped by both hands, the power switch 12 is turned on (the power cord is not shown), and the polishing section 5 is rotated to rotate the surface to be polished. Is moved while pressure is applied, and the surface to be polished is thereby polished. The above-mentioned polishing base material of the polishing section 5 includes sponge, nylon brush, sandpaper, etc., and the polishing section 5 is appropriately replaced according to the purpose of polishing. Since the lubricant 13 on the bottom of the case 1 presses and slides on the surface to be polished, a relatively soft metal plate, plastic, vinyl sheet or the like is appropriately replaced according to the surface to be polished.

[0004]

[Problems that the device is trying to solve]

 However, in the polishing apparatus having the above-described configuration, the roll-shaped polishing section 5 is always rotating in a fixed direction, so that a force in a fixed direction always acts during the polishing operation. For example, when the polishing unit 5 rotates in the direction of arrow A shown in FIG. 4, the polishing apparatus itself exerts a force in the direction of arrow B in FIG. In general, when the surface to be polished is polished by the above-mentioned apparatus, the grips 11 and 11 'are grasped by both hands, and the polishing surface is sequentially expanded while the polishing apparatus is moved back and forth. However, since a force in a certain direction acts on the polishing device as described above, the force applied to both hands is different each time the polishing device is moved forward and backward, and the polishing operation becomes very unstable. Therefore, it becomes difficult to uniformly polish the surface to be polished.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a polishing apparatus which does not exert an extra force even during polishing and has good operability. is there.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a polishing apparatus for polishing a surface to be polished by rotating a roll-shaped polishing section by decelerating a rotating force of the electric motor and the electric motor in a case. The two rotating bodies that are arranged in parallel with each other, transmit the rotational force of the electric motor, and rotate independently of each other in the same direction and the opposite direction with respect to the rotating direction of the electric motor; and the two rotating bodies. And a transmission means for transmitting the rotational force of the above to the two roll-shaped polishing parts.

[0007]

[Action]

 According to the above-mentioned two-roll type polishing device, since the polishing device is provided with the two polishing parts rotating at the same speed and opposite to each other, the forces generated by the rotation of one polishing part cancel each other out. No extra force is applied during the polishing operation, and stable polishing operation is always possible. Even when the polishing device is moved forwards and backwards to polish the surface to be polished, two polishing parts that rotate in opposite directions are provided, so that the polishing device is always constant regardless of the operating direction of the polishing device. Since the polishing action of the above affects the surface to be polished, the polishing efficiency is remarkably improved.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. An electric motor 14 is housed in a case 13, and a gear 16 is directly connected to a rotary shaft 15 of the electric motor 14. The gear 16 meshes with a first gear 17, and the first gear 17 meshes with a second gear 18 having the same diameter as the gear 17. A first pulley 19 and a second pulley 20 are directly connected to the respective rotary shafts of the first gear 17 and the second gear described above, and the rotation speeds of the two pulleys 19 and 20 are In parallel, the rotation directions are opposite to each other due to the relationship between the first and second gears described above, and have the same rotation speed. On the other hand, the case 13 contains a first polishing section 21 and a second polishing section 22 each having a roll shape, and the respective rotary shafts 23, 24 of these two polishing sections 21, 22 are mutually Installed in parallel, a first pulley 25 and a second pulley 26 for rotating the two polishing parts 21, 22 are installed on an extension of the two rotating shafts 23, 24. The pulleys 25 and 26 are provided with two belts 27 and 28 between the first pulley 19 and the second pulley 20 which are directly connected to the rotating shafts of the first and second gears 17 and 18, respectively. It is rotationally connected with. Further, in order to facilitate maintenance and inspection, the above-mentioned gears, pulleys, etc. are all housed in the gear box 29 as in the conventional example.

Next, the operation of the polishing apparatus according to the present invention will be described. Now, assuming that the power switch 30 is turned on and the rotation direction of the electric motor 14 rotates in the direction of arrow A in FIG. 1, the rotation directions of the first gear 17 and the second gear 18 are indicated by arrows B and C in FIG. At the same time, they rotate in the opposite directions to each other, and at the same time, the rotation speed becomes the same. Further, the first and second pulleys, which are coaxial with the two gears 17 and 18, are connected to the first and second pulleys 25 and 26 for rotating the polishing portion by the two belts 27 and 28. Therefore, the two roll-shaped polishing parts 21 and 22 are rotated in opposite directions as shown by arrows D and E in FIG. (However, the diameters of the first and second pulleys 19 and 20 and the first and second pulleys for rotating the polishing portion are the same.)

As described above, in the polishing apparatus according to the present invention, the two roll-shaped polishing portions rotate at the same speed in the opposite directions, so that the forces generated by the rotation of one polishing portion cancel each other out. Therefore, as seen in the conventional polishing apparatus, the force generated by the rotating direction of the polishing section or the force applied in the left-right direction when the force pressing the polishing apparatus against the surface to be polished becomes uneven is almost generated. Therefore, the operability of the polishing apparatus is significantly improved. Furthermore, in the case of one polishing section, the difference in polishing force that occurs when the polishing apparatus is moved back and forth is eliminated by reversing the two polishing sections, and the polishing efficiency is significantly improved. Become. Incidentally, the polishing base material of the polishing section described above can be arbitrarily replaced according to its purpose, and this is the same as the conventional apparatus. In the above embodiment, the case where the electric motor is used as the prime mover has been described, but it may be replaced with an air motor.

[0011]

[Effect of the device]

 As is clear from the above description, according to the polishing apparatus of the present invention, the unstable force unlike the conventional apparatus does not act, so that the operability is significantly improved and the polishing efficiency is also improved. The effect is demonstrated.
