Abstract

PURPOSE:To automatically polish alternately the front and back faces of a base stone, etc., by installing a color discriminating photoelectric device at the upper side of an electromagnetic return device. CONSTITUTION:A material is optionally input into a material hopper 2, is accumulated and a screw conveyor 5 is made movable by a motor for the screw conveyor, then, the material hopper 2 causes a slight earthquake by a vibrator 3. A raw material or material is interposed between each walls of the screw conveyor 5 by the slight earthquake even in the case of being accumulated alternately in whatever direction and is held in the same state, it is ascended by the screw conveyor 5 and falls in the horizontal shape on a crosswise gutter 7. Moreover since the crosswise gutter 7 is provided by making it in a slope shape discent likely, the material is slided in descent when a slight vibration is given by a vibrator 8. Then, when it is positioned on the electromagnetic return device 11, the front and back are discriminated by a color discriminating photoelectric device 10, the back face is made in a constant position with its reversing to the surface, passed into a six axes polishing machine 15 and polished in a desired shape by this polishing machine 15.

Description

Detailed Description of the Invention (a) Industrial Application Field This invention is a polishing method in which, when polishing a series into an elliptical or spherical shape, one side is polished into an elliptical or spherical shape one by one, and both sides are polished by automatic polishing alternately. Regarding machines.

(b) Conventional technique: When cutting and polishing hard raw materials or materials, the raw materials or materials are machined into individual pieces and each side is shaved, and the front and back surfaces are polished through several steps. It was polished and made into a spherical or oval shape.

(c) Problems to be Solved by the Invention As described above, polishing of spherical or elliptical spheres is carried out by separating the front and back surfaces, but each is finished by hand in one piece, which is expensive and time-consuming. There were problems such as severe fatigue and increased fatigue, which hindered efficiency and also resulted in an unsightly finish.

(2) Means for solving the problem As mentioned above, in spherical or elliptical surface polishing,
It is necessary to polish with a hand-held press each time, and it has to be repeated several times, so it is difficult to make the product consistent.In addition to achieving a beautiful high gloss, it is also possible to automatically solve various problems in grading the shape. The present invention is intended to provide the following.

To explain the present invention with reference to the drawings, raw materials or materials having approximately the same shape and having an appropriate shape are transferred to an inverted pyramid material hopper 2.
A screw conveyor 5 equipped with a vibrator 3 is installed along one side wall of the material hopper 2, and a U-shaped horizontal gutter 70 is connected to the top of the horizontal gutter 70 by lowering its top end. m7, electromagnetic lowering devices 9 and 12 are placed in series on both sides of the polishing machine mount 6 on the upper frame side with the magnetic return device 11 in the center, and the color identification photoelectric device 10 is placed between the electromagnetic return device and the magnetic return device 11. Installed opposite to 11, fixed gutter 13
is placed downwardly at the end and slid onto the outer peripheral surface of the six-axis polisher 15 provided in the polisher mount d.Furthermore, holders 14 are attached to the six-direction axes of the six-axis polisher 15, respectively. , a motor 21 for rotating the holder is provided at the lower part of the outside, and a motor 20 for moving the six-wheeled polishing machine is attached to the polishing MfJa frame 6.
The polishing machine is installed on the lower frame and connected to the central axis of the six-axis polisher 15, and the pendulum-type motor mounting base 16 is fixed to the center of the upper frame of the polisher mount, and the polishing stone 17 is externally covered. The purpose of the present invention can be achieved by having the structure as described above, in which the product bucket 19 is installed under the polishing machine stand O.

(e) Function The present invention is mainly used for polishing Go stones. To explain the function of the polishing, the material hopper 2 stores suitably processed small hard materials, and is used for screw conveyors. By rotating the motor, the small material is squeezed between the walls of the screw conveyor 5 and raised upwards, while the body movement of the vibrator 3 constantly causes the screw conveyor 5 to slightly oscillate and rise. The material is conveyed to the horizontal gutter,
The small materials are flattened and moved on the bottom surface of the horizontal straight gutter 7 by the vibrator 8.
The radius of the screw conveyor 5 and the distance between the screws are set somewhat larger depending on the size of the shape of the material, so that the vibrator 3 can feed the material as much as necessary.
While moving, the screw conveyor 5 is sandwiched between the walls of the screw conveyor 5 and lined up in a line, and transported to the upper part.
It is conveyed in a horizontal state, and is tilted downward due to the vibration of the pie break 8, so it slides down and reaches the magnetic lowering device 9, and by further vibration, it reaches the electromagnetic lowering device 12, and the color is lowered. When the identification photoelectric device 10 completes production 11 and the color identification photoelectric device 7110 changes the material in the required direction using a sensor, the material slides down the horizontal gutter and falls into the fixed gutter 13. Holder 14 + at the end
-, +1 Since the holder 14 is rotated by a bevel gear on the central axis, and the six-wheel polisher 15 is also rotated, the surface of the material is polished by coming into contact with the grinding stone 17 by the rotation of the six-wheel polisher 15. In circular grinding, a one-side polished product of the required shape is made by sliding it on the grinding stone 17 using the holder l4, and loading it into the product pail 19.The products in the product pail 19 are further transferred to the material hopper 2. If the unpolished side is turned over using the color discrimination photoelectric device 10 and the operation is performed again, it will become double-sided spherical or
It is possible to obtain a double-sided elliptical spherical shape.

(f) Example Raw material 1 manufactured by a ready-made Go stone raw material crusher, or
Materials are arbitrarily put into the material hopper 2, and accumulated.
When the screw conveyor 5 is moved by the screw conveyor motor, the material hopper 2 causes a slight tremor due to the pie break 3.The slight tremor causes the material hopper 2 to vibrate even if the raw materials or materials are accumulated alternately in any direction. The raw materials or materials are kept in the same condition by being tightly packed between each wall, and are raised by a screw conveyor 5 and passed through a horizontal gutter 7.
The electromagnetic return device 1 falls horizontally, and since the horizontal gutter is sloped downward, it slides downward when the vibrator 8 supports a slight tremor.
In order to keep the front and back sides constant when the paper is placed on the top surface of the paper, the back side is turned over to the front side, placed in a fixed position, and sent into the six-axis grinder M machine 15.The six-axis grinder 15 polishes it into the required shape, and furthermore, the outer periphery is The grinding stone 17 is covered and the &Hil motor 18 is moved to create the shape.Once one side is completed, it is put into the product bucket 192.If the material is returned to the material hopper 2 and the same process is repeated, both sides are polished completely. It becomes a product.

(G) Effects of the Invention As described above, since the work is not done manually but automatically, the effects brought about by this invention are the most remarkable as follows.

(1) The machines are extremely easy to handle, and one person can operate several machines without the need for manpower.

(2) Since one person can handle several machines, one person can continuously produce a large RK production capacity, which allows for a stable supply of products and enables the supply of inexpensive, high-quality products.

(3) Machine operation reduces costs and improves efficiency.
