POLISHING APPARATUS
BACKGROUND OF THE INVENTION
Field of the Invention . _ The present invention relates to a polishing appa-ratus, particularly a polishing apparatus which polishes workpieces to be polished by rotating a polishing bath which is charged with the polishing materials and the workpieces to be polished.
Description of the Prior Art A polishing apparatus has been used which carries out fluid polishing against workpieces to be polished by rotating a polishing bath wherein polishing materials and the workpiecesto be polished are charged.
One example of the conventional polishing apparatus of the above type is such that as shown in FIG. 4, where a polygonal cylindrical polishing bath B provided with a rotating shaft A is borne on a stand C at the both ends of the rotating shaft A. At an end of the side of the polishing bath B, an opening D is formed, thereon a cover E is set removably by means of screws.
A pulley F, on the other hand, is secured to the rotating shaft A such that the shaft A is rotated by means of a motor G via a belt H.
In the conventional polishing apparatus, upon taking 2~03~
off a cover E, polishing materials J and workpieces to be polished K are charged in a polishing bath B leaving such space as they can freely be flown in said polishing bath B.
The opening D is then closed with the cover E fixed by means of the screws and then the motor is driven so as to have the polishing bath B rotated around the rotating shaft ~.
The polishing materials J and the workpieces to be polished K flow rubbing each other in the polishing bath by the rotation thereof.
In the aforementioned polishing apparatus, however, as the rotating speed is accelerated, the centrifugal force acting on the polishing materials and the workpieces to be polished in the polishing bath will be increased resulting in such state as thay will be jammed to the inner peripheral surface of the polishing bath. In such a state, the polishing materials and the workpieces to be polished will become to stay statically on the inner peripheral surface to such extent as the contact flow between them does not occur resulting in no polishing action between them even with the polishing bath ratated.
In the conventional polishing apparatus, therefore, the polishing bath should be rotated at alower rotating speed so as not to increase the centrifugal force acting on the ~00~
pollshing materlals and workpieces to be polished. This only gave not so hlgh polishing efficacy to the workpieces to be polished.
SUMM~RY OF THE INVENTION
The present invention has been accomplished in vlew of the foregoing situation for the conventional pollshlng apparatus, and lt is, therefore, that an object of the present lnvention is to provide a pollshlng apparatus whlch ls capable of high efflciency polishing for a large amount of workpieces to be polished by rotating the polish-ing bath at a high rotating speed.
To accompllsh the foregolng object of the present lnventlon, the present invention comprises a sub-rotating shaft, dlsplaced radially from the maln rotation center, mounted on a rotator which rotates around the main rotation center; a circular or polygonal type cyllndrlcal pollshing bath in which polishlng materials and workpleces to be polished are charged; a drlvlng means rotating said sub-rotating shaft at fixed velocity ratio and in a fixed rotational direction in relation to said center of the main rotation, said sub-rotating shaft being borne at its both ends using the rotator.as a balance wieght or by disposlng rotators oppositely at the both sides respecteve-ly of the apparatus.

One example of the conventional polishing apparatus of the above type is such that as shown in FIG. 4, where a polygonal cylindrical polishing bath B provided with a rotating shaft A is borne on a stand C at the both ends of the rotating shaft A. At an end of the side of the polishing bath B, an opening D is formed, thereon a cover E is set removably by means of screws.
A pulley F, on the other hand, is secured to the rotating shaft A such that the shaft A is rotated by means of a motor G via a belt H.
In the conventional polishing apparatus, upon taking 2~03~
off a cover E, polishing materials J and workpieces to be polished K are charged in a polishing bath B leaving such space as they can freely be flown in said polishing bath B.
The opening D is then closed with the cover E fixed by means of the screws and then the motor is driven so as to have the polishing bath B rotated around the rotating shaft ~.
The polishing materials J and the workpieces to be polished K flow rubbing each other in the polishing bath by the rotation thereof.
In the aforementioned polishing apparatus, however, as the rotating speed is accelerated, the centrifugal force acting on the polishing materials and the workpieces to be polished in the polishing bath will be increased resulting in such state as thay will be jammed to the inner peripheral surface of the polishing bath. In such a state, the polishing materials and the workpieces to be polished will become to stay statically on the inner peripheral surface to such extent as the contact flow between them does not occur resulting in no polishing action between them even with the polishing bath ratated.
In the conventional polishing apparatus, therefore, the polishing bath should be rotated at alower rotating speed so as not to increase the centrifugal force acting on the ~00~

SUMM~RY OF THE INVENTION
The present invention has been accomplished in vlew of the foregoing situation for the conventional pollshlng apparatus, and lt is, therefore, that an object of the present lnvention is to provide a pollshlng apparatus whlch ls capable of high efflciency polishing for a large amount of workpieces to be polished by rotating the polish-ing bath at a high rotating speed.

As the present invention is constituted as described above, the sub-rotating shaft revolves both round the main rotating shaft and simultaneously on its own axis at fixed velocity ratio and in fixed rotational direction by the driving means provided respectively on the center of the main rotation and between the main rotation center which has no through-shaft ~a revolution shaft) and the sub-rotating shaft. In the present invention the polishing bath, therefore, rotates on its own axis of the sub-rotat-ing shaft and simultaneously revolves round the main rotating center remaining upon a locus drawn by the center displaced radially of the rotator having the main rotation center. In the polishing bath, therefore, the polishing materials and the workpieces to be polished can always be flown in contact each other to accomplish an effective polishing at a high rotating speed without leaving both of the polishing materials and the workpieces to be polished in any static state because of the centrifugal force.
In addition, due to a non-restricted diameter allowed for the polishing bath because of the existence of the revolution shaft, an effective polishing of the workpieces to be polished in a polishing bath of large capacity can be achieved.
BRIEF DESCRIPTIQN OF THE DRAWINGS
2~3~8~i Fig. 1 is a front view showing the constitution of one example of the present invention, Fig. 2 is a side view showing the constitution of the present invention, Fig.3 is an explanatory view of the example of the present invention, and Fig.4 is a front view of the prior art apparatus.
DETAILED DESCRIPTION OF PREFERRED EMsoDIMENTs The embodiments of the present invention will now be described with reference to the accompanying drawings.
Fig.l and Fig.2, showing the constitution of the present invention wherein like parts are designated by like reference numerals, are the front and side view respectively of the embodiment of the present invention.
In the embodiment, the rotating shaft 11 is divided in two portions and they are pivotably borne on the right and left sides of the stand 3 respectively. To this rotating shaft 11, the balance weights 12, 13 of the same shape are fixed respectively.
Further, these balance weights 12, 13 may be of simple rotator and not necessarily provided particularly at the both ends oppositely of apparatus or formed into an inte-grated through-shaft as the rotating shaft is only for bearing the center of rotation of the rotator 12 tthe main rotation center). tThe balance weight is hereinunder 2~0~8S
referred to as a rotator).
Cne sub-rotating shaft 14 is fixed pivotably at a place radially displaced from the center of the main rotation center of said rotators 12, 13 and one hex-cylindrical polishing bath 2 is fixed to the sub-rotating shaft 14. On the inner surface of this polishing bath 2, coating such as rubber is applied throughout the surface withunevenness formed on the rubber surface.
A pulley 15 is fired to the one side of the rotating shaft 11 bearing said polishing bath 2, said pulley being belted with a belt 8 which is driven by a motor 7 mounted on the stand 3 so as to rotate the pulley 15 via the belt 8 thereby rotating the said rotating shaft 11.
Further, a pulley 16 having,as its center, the rotating shaft 11, the rotation of which is driven by the motor 7, or a pulley 16 integrated with a chain gear, sprocket gear, etc. which is rotated by a driving means such as transmission geared motor ~ia chain, is fixed to the rotating shaft 11. On the other hand, a pulley 17 is fixed to the sub-rotating shaft 14 which is disposed radially displaced from the rotating center of the rotat-ing shaft 13 side of the polishing bath 2. These pullies 16, 17 are belted each other with a belt 18. Further,in the embodiment, the covers 5 are mounted in 2 places on ~20q~3~8~i the both end sides of the polishing bath 2.
In the embodiment, as the diameters of the both pullies 16, 17 are set e~ually, when the main rotation center llC rotates one round thus the rotator 13 rotates, the polishing bath 2 revolves on the locus drawn by the shaft displaced radially of the rotator 13 and at the same time the sub-rotating shaft 14 rotates a fixed member of rounds. The polishing bath 2 is so constituted to make rotation as described above.
Further, these is provided an unloading guide 19 on the stand 3 changeably in unloading direction located adjacent to the cover 5 of the rotator 13 side, and to this unloading guide 19 a mesh 20 is fitted. The constitution of other portions of the embodiment is the same as the conventional polishing apparatus described already refer-ring to Fig. 4.
The behavior of the embodiment will now be described hereinunder.
In Fig. 1, the polishing materials and the workpieces are loaded into the polishing bath 2 through the opened cover 5 at the side of the balance weight 12 to such e~tent as leaving an enough flowing space in the polishing bath for the loads.
The over 5 is screwed for flxing, thereby the 2~0~
polishing materials and the workpieces to be polished are then contained in the polishing bath. The motor 7 is then driven to rotate the pulley 15 via the belt 8. The rotation of pulley 15 gives rotation to the rotating shaft 11 at the fixed rotating speed. By the rotation of this rotating shaft 11, the polishing bath 2 is revolved round the rotation center llC of the rotator 13 remaining upon the circular orbit Ql drawn by the axis 14C of the rotat-ing shaft 14.
Simultaneously with this revolution, the rotation of the rotating shaft 11 is transmitted to the sub-rotating 14 via the pulley 16, belt 18 and pulley 17 to rotate the rotating shaft one round, thereby rotate the rotators 12, 13 in a fixed number of rounds to rotate the polishing bath 2 round the sub-rotating shaft 14 in the fixed number of rounds.
Fig. 3 shows the condition of revolution of the polishing bath 2 round the rotation center llC of the rotator 13 and also that of the rotation of the polishing bath on the axis l~C of the sub-rotating shaft 14 in the process of this revolution both in the embodiment. For example, an arris Al of the polishing bath 2 is moving as illustrated. By the rotation of the polishing bath 2, the centrifugal force f due to the revolution of the g _ 2003~
polishing bath 2 and the centrifugal force and gravity due to the rotation of the polishing bath itself act on both of the polishing materials and workpieces to be polished to flow in contact each other to polish the workpieces.
Further, the inner wall of the polishing bath moves relatively against the polishing materials and the work-pieces to be polished. As described previously, the inner wall of the polishing bath is coated with rubber having an uneven surface, and by such rubber application, both of the polishing materials and the workpieces to be polished lying adjacent to the inner wall of the polish-ing bath are stirred up each other to enhance the polish-ing efficacy.
Upon completing a full polishing operation, the motor 7 is stopped and the cover-5 of the balance weight 13 side released to get the polishing materials and the workpieces unloaded from the polishing bath 2 into the unloading guide 19 with the workpieces resting on the mesh 20 and separate-ly the polishing materials passing therethrough to the bottom of the unloading guide 19 for taking out.
Thus, according to the embodiment, as there ne~er happen such case as the polishing materials and the work-pieces to be polished come to a standstill being jammed to the wall surface of the polishing bath 2 due to the )3~ ~3rj centrifugal force, the workpieces can effectively be polished by rotating the polishing bath 2 at a high rotating speed. In case o the rotators 12, 13 being mounted as balance weight, the moment applied to the rotators 12, 13 is so balanced as the rotation of the polishing bath 2 can smoothly be carried on to prevent the rotating shaft 11 from any breaking by unbalanced load applied to the rotating shaft 11, thereby a high speed operation can safely be achieved. Further, because of no rotating shaft provided on the rotator as the conventional one does, the diameter of the-polishing bath is not restricted by the shaft mentioned above and can be large enough.
Further, the embodiment was illustrated to constitute such that the rotator and the sub-rotating shaft rotates at the same velocity ratio and in the same rotational direction, the polishing bath is kept level, and the interior of the polishing bath is made of uni-chamber.
The present invention, however, is not limited to the embodiment, and can be such that, for example, the rotators and the sub-rotating shaft are arranged with a longitudinal inclination or the interior of the polishing bath is divided into a plurality of chambers.
The embodiment was illustrated also to constitute Z~3~
such that the main rotating shaft side and the sub-rotating shaft side are connected via rollies and belt. The present invention however, is not limited to the embodiment, and can also be such that the both are connected by means of gears and chains or with gears.
Thus, according to the present invention, it is advantageous in that an effective and safe polishing of workpieces to be polished can be achieved by establishing various conditions of stirring-polish by selecting the driving means without the polishing materials and the workpieces to be polished being jammed to the inner surface of the polishing bath at a standstill due to the centrifu-gal force even when driven at a high speed; the polishing bath can be large enough suitable to make a bulk production of polished workpieces as the rotators have no rotating shaft; and the revolution and/or rotation of the polish-ing bath can very effectively be smoothened by having the rotators as balance weight or the rotators arranged at the both sides of the apparatus borne at the both ends of the sub-rotating shaft.
As the present invention is constituted as described above, the sub-rotating shaft revolves both round the main rotating shaft and simultaneously on its own axis at fixed velocity ratio and in fixed rotational direction by the driving means provided respectively on the center of the main rotation and between the main rotation center which has no through-shaft ~a revolution shaft) and the sub-rotating shaft. In the present invention the polishing bath, therefore, rotates on its own axis of the sub-rotat-ing shaft and simultaneously revolves round the main rotating center remaining upon a locus drawn by the center displaced radially of the rotator having the main rotation center. In the polishing bath, therefore, the polishing materials and the workpieces to be polished can always be flown in contact each other to accomplish an effective polishing at a high rotating speed without leaving both of the polishing materials and the workpieces to be polished in any static state because of the centrifugal force.
In addition, due to a non-restricted diameter allowed for the polishing bath because of the existence of the revolution shaft, an effective polishing of the workpieces to be polished in a polishing bath of large capacity can be achieved.

On the other hand, a pulley 17 is fixed to the sub-rotating shaft 14 which is disposed radially displaced from the rotating center of the rotat-ing shaft 13 side of the polishing bath 2. These pullies 16, 17 are belted each other with a belt 18. Further,in the embodiment, the covers 5 are mounted in 2 places on ~20q~3~8~i the both end sides of the polishing bath 2.

Fig. 3 shows the condition of revolution of the polishing bath 2 round the rotation center llC of the rotator 13 and also that of the rotation of the polishing bath on the axis l~C of the sub-rotating shaft 14 in the process of this revolution both in the embodiment.
