Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lens polishing machine, and more particularly to a fully automatic polishing apparatus for small and medium diameter precision coccal lenses.

Lens polishing devices that have been commonly used can be roughly divided into two types depending on whether the direction of the tip of the holder shaft (gunzashi stick) always pressurizes the cocci in the polishing dish or not. can. The present invention belongs to the latter category, and is primarily an apparatus for polishing lenses by shaking cocci in a polishing dish. This device also has two methods: one in which the center of the oscillation is the cocci of the lens R and polishing plate R, and the other in which the holder shirt I is swung toward the cocci.In the former, the angle of the lens changes. Therefore, unbalanced pressure is always applied to the lens, which not only worsens the reproducibility of lens H, but also causes the polishing plate to wear out very quickly.
It is necessary to frequently readjust the polishing plate R and readjust the swing angle and width. Further, although the latter poses no problem in the case of a concave lens, many problems arise when polishing a convex lens.

Therefore, the applicant of the present application has developed a technology to solve the above-mentioned drawbacks and problems, and the contents thereof are as disclosed in the previous application (Japanese Patent Application No. 1987-742H). The present invention is also an improvement of this invention.

BACKGROUND OF THE INVENTION As shown in FIG. 6, a conventional polishing method involves installing a drive shaft with a spindle in the center of a cylindrical box.
A polishing booklet with a spherical recess is attached to the tip of the drive shaft, and a V-pulley is attached to the other end, which rotates the polishing mt via a motor, and a center shaft is attached above the box. A #F polishing IHt rotating and swinging mechanism (A) that swings the entire box in a pendulum shape via a bearing, and a holder shaft with a polishing holder connected to the upper part of the polishing plate are fixed, and the boulder A polishing holder fixing and pressing mechanism (B) is provided, in which a holder arm with a pressure ring is attached to the arm shaft, and the lens L is placed between the polishing plate of both mechanisms and the polishing holder, and the polishing plate is rotated. This is a method of polishing lenses by rolling and shaking them. The principle is as shown in Figures (b) and (c), the polishing plate rotates and oscillates around the coccus P of the plate R (lens R), while the polder shaft rotates around the polishing plate. is fixed and pressurized perpendicular to the Therefore, the polishing Inl where the lens L is currently placed is moved from A to B.
When the lens L is moved by an angle of −e in the direction of Try to escape to a lower position. In other words, the lens L is forcibly brought into contact with the entire surface of the polishing plate without changing its position.

In this way, in the conventional polishing method, the polishing plate is oscillated by rotating a cam or crank via a motor, so the load on the downward swing mechanism is increased by +j depending on the rotation angle of the cam or crank, and the swing speed is increased. It became unstable, and it was difficult to increase the number of swings. That is, when a lens is polished by a downward swing mechanism, the lens is usually polished at an arbitrary angle of 45° from Oo in the polishing dish, and in this case, the polishing dish is polished at an arbitrary angle of 45° from Oo. oscillate. In order to swing the polishing plate at this time, the entire swing base must be swung, and a considerable amount of weight is added, making it impossible to perform a good swinging motion. As a result, the following drawbacks arise. (1) When the swinging direction goes up (toward 0' to 45°), the motor is loaded with all the weight including the swing base, and conversely, when the swinging direction goes down (towards 45° to 0°) The motor (when moving toward the center) is pushed by the weight of the load, resulting in uneven swing speed. (2) Also, when the oscillation is downward, the motor works in the direction of applying the brake and accelerates in the opposite direction, and at the next oscillation return point approaching O°, the cam and crank suddenly The vehicle is braked and momentarily swung in the opposite direction. At this time, a severe shock occurs, and creating a mechanism that can withstand this poses many problems both structurally and economically. Furthermore, although it is possible to perform deceleration swinging in order to eliminate this shock, it is impossible to do this via a motor. (3) To adjust the cam and crank, the fulcrum must be changed, which is practically impossible to adjust, and when changing the swing angle and swing 11, each must be set separately. Moreover, since everything is adjusted by hand and feeling, there is no reproducibility. Of course, fine adjustment is not possible at all.

The present invention solves the technical problems previously developed by the applicant as described in "Problems to be Solved by the Invention," and further automates and unitizes all operations and operations, including this polishing method. Therein lies the problem that the present invention attempts to solve. That is, the problem can be solved by making the operation steps of supplying, polishing, and removing the lens to be polished a fully automated continuous process.

Means for Solving the Problem The present invention was developed in order to solve the above-mentioned problems, and includes providing a workpiece in which a polishing lens is stored in the case, and transporting the workpiece via a belt conveyor. There is a lens supply mechanism that sequentially transports and supplies the lenses to the polishing machine, and the lenses in the workpiece toy transferred from the lens supply mechanism are transported and positioned to each polishing tank, and the processes of pellet rejection, R comparison measurement, resin processing, and discharge are carried out. A lens polishing mechanism that performs one cycle, and a lens polishing mechanism that conveys and positions lenses transferred from the polishing machine via a belt conveyor to each polishing machine, and polishes them through the steps of supply, polishing, and discharge. All of these problems were solved by using an automatic lens polishing device that includes a lens removal mechanism that cleans the lenses transferred via a belt conveyor after polishing is completed in a water tank. . In other words, the solution to the problem is: 1) automating the so-called polishing process of supplying, polishing, and removing the lens, and making these operations a continuous process; 2) using a belt conveyor to transport the lens between each process; Using ■
The conveyance and positioning mechanism to the lens polishing tank is performed by an air cylinder; () The lens conveyance and positioning mechanism in which the polishing mechanism rotates the four wooden base axes in pitch increments of one-fourth, and the two horizontal base axes operate simultaneously. This includes the use of a lens transport and positioning mechanism.

Embodiment and its operation FIG. 1 shows the overall mechanism of the automatic lens polishing apparatus of the present invention. The apparatus of the present invention is comprised of a lens supply section (A), a lens fine grinder body (B), a lens polisher body (C), and a lens removal section (D). ■The supply section (A) is a mechanism that sequentially supplies workpieces containing lenses to the fine grinding machine body (B) using a belt conveyor.

It is a mechanism that finely polishes the lens by performing 17 steps in one cycle, and after fine polishing, the main body of the polishing machine (C) re-grinds the lens sent by the belt conveyor. It is a mechanism that rotates and polishes lenses through simultaneous supply, polishing, and discharge processes, and the removal section (b) is a mechanism that shower-washes the lenses sent by the belt conveyor again after polishing is completed. . As is clear from this figure, the lenses are conveyed by a belt conveyor installed in front of this device, and all operations and operations are controlled to ensure automatic and continuous operation. There is. Note that the polishing method and equipment for the fine grinding machine body (B) and the polishing mechanism body (C) are basically the same.

FIG. 2 shows the lens supply section (A) of the apparatus of the present invention. This lens supply section (A) is a device for conveying and supplying the workpiece toy W containing the lens L to the fine grinding machine main body (B) via a belt. Reference numeral 1 denotes a base, on which a blade 2 is mounted via a screw shaft 3. The screw shaft 3 is attached to the base l via a bearing 4 with a stopper 5.

Figures (A) to (C) show the precision grinding machine main body (B) of the present invention.
This is an overall overview of the As is clear from this figure, the precision grinding machine body (B) has four lens conveyance and positioning mechanisms (S) that rotate at a pitch of every quarter of the circle.
are installed in a criss-cross pattern. Take it in a cross shape like this 4
The 1 digit is made by rotating the pitch around the circle every 90 degrees,
Lens polishing mechanism installed in 3 locations (b, c,
d) This is for sequentially moving the lens transport and positioning mechanism (S) upward. Note that the position (a) is where the lens is supplied and removed. The specific structure and operation thereof will be explained below. The loading table 11 is centered around the center shaft 13, and the loading arm 1
The table is attached to the top of 2 by screwing at 19.

Four lens transport and positioning mechanisms (S) are installed at the ends of the rope and inog arm 12 around the circle, and an air tube 21 for suctioning the workpiece is installed at each upper end. . This air tube 21 is connected to the center shaft +
3, and are connected to a vacuum generator (not shown) via a center shaft 13 and a rolling air joint 22 at the lower end. In addition, the center shaft 13 has a slide metal 1
6 and is fixed to a base 28 via a bearing 18. Reference numeral 23 denotes a sleeve, into which a timing pulley 17 is inserted and connected with a key 15. This timing pulley 17 is placed along the keyway 14 in the center shirt]・! 3 moves seven positions, and is linked to the turn motor 18 via the timing belt 24, and rotates the center shaft 13 when the loading table 11 is 1-A.
1 can be rotated. Furthermore, the lower end of the center shirt) 13 is made of cylinder metal 2.
An air cylinder 27 is connected via 6. This air cylinder 27 causes the entire loading table 11 to move two feet. That is, the loading table 11 is lowered when polishing a lens, and is raised while simultaneously rotating and lowered when transporting the lens. In other words, the polishing lens is vacuum-adsorbed to the polishing holder, which is an extra edition, at the tip of the lens transport and positioning mechanism (S), (S 1) (S 2) (S 3)
They are transported sequentially to Then, when polishing, the vacuum state is turned off and each lens polishing mechanism (b, c, d)
It is rotated and swung freely on the polishing plate. In this way, the lens polishing holder is provided at the tip of the lens transport positioning mechanism (S), and the lens polishing holder is characterized in that it also serves as the lens transport head.

FIG. 3(d) shows the main parts of the lens transport and positioning mechanism (S). 28 is Hordon Yaft,
It is fixed vertically as before. 30 is a piston provided on the holder shaft 29, and is extended by a sliding metal 31 via a packing 38. 32 is a cylinder tube, which is fitted onto the outer periphery of the holder shaft 29 to which the piston 30 is attached. This cylinder tube 32 is provided with an outlet for compressed air (H) (I) via an air joint 33.40. Furthermore, the cylinder head 34 is installed in the cylinder tube 32 on the L side, and a metal 35 is installed inside through a backing 37, while the cylinder tube 32 on the lower side is equipped with a screw I/lock nut 39. The piston 30 is opened and shifted. Note that 41 and 42 are O rings, and 43 is a holder head. 46 is a center lock nut of the rolling center 50 installed in the center of the holder shaft 28, and 47 and 48 are its radial bearing and thrust I-bearing. 48 is a center nut, and 51 is a center point. 45 is a polishing plate on which the lens L is placed. In addition, 52 is the holder shaft 28
53 is a stop ring.

Next, the operation of the above mechanism will be explained.

First, when polishing the lens L, pressure is applied to the lens L on the polishing plate 45 via the holder shaft 28 of the polishing holder 44, and the polishing plate 45 is rotated and swung. Next, when transporting the polished lens L, the lens L is attracted to the polishing holder 44, transported to a certain location, and removed. In this way, the supply, conveyance, and removal of the lens L during polishing and conveyance are made automatic, and its positioning is performed accurately and reliably. More specifically, when polishing the lens L, compressed air (H) is flowed into the cylinder tube 32 to compress the space between the holder shaft 28 and the inside of the cylinder tube 32 (in a sealed state). the piston 30 is slid upwardly via the sliding metal 31. This piston 3
The holder shaft 28 is pushed in the negative direction within the cylinder tube 32 by the one-way movement of the cylinder tube 32. This is because the holder shaft 29 is constantly pressed downward by the compression spring 32. In this manner, when the holder shaft 29 is moved in the negative direction, the lower end of the cylinder tube 32 is moved away from the rad 43 to the holder of the polishing holder 44 and locked to the piston lock nut 39. As a result, compressed air (I
) does not flow into the polishing holder 44, so the polishing plate 45
is freely rotated and swung, and the lens L is polished. Next, when transporting the lens after lens polishing, if the compressed air (H) in the cylinder tube 32 is released, the holder shaft 28 is pressed downward via the compression spring 52, so the piston 30 is
It is slid downward within the cylinder 32. Due to this construction movement of the holder shaft 28, the lower end of the cylinder tube 32 is separated from the piston lock nut 39 and connected to the holder head 43.

By connecting the cylinder tube 32 and the polishing holder 44, the compressed air (I) is communicated with the polishing holder 44, so if it is in a vacuum state, the lens L on the polishing plate 45
will be attracted to the polishing holder 44. It can be transported in this adsorbed state as it is. Moreover, since the center line of the polishing holder 44 during transportation is located on the center line -F of the holder shaft 29, it can always be kept upright in a vertical state. In addition, since the lens L is attracted to the polishing holder 44 in a vacuum state, the airtightness is extremely high, and it is possible to reliably prevent the lens L from being left on the polishing plate 45 or falling off during transportation. You can also do it.

FIG. 3 (e) shows the lens polishing mechanism (b).

The swing mechanism of the polishing book which is the main part of c and d) is shown, and 54 is its swing cylinder. 55 is a swing boss that connects the swing cylinder 54 and the spindle 64, and 56 is a bearing thereof. It is a cylinder foot fixed to a 5'1 frame 58, and a swing cylinder 54 is attached via a bin 58. 60 is a spindle motor, which connects the spindle 84 via V-pulleys 61 and 62 and a belt 63.
is linked to. The spindle 64 is connected to a polishing plate 68 inside a sleeve 65 via a bearing B7.

That is, by driving the spindle motor 60, the swivel spindle 64 is rotated and the polishing plate 88 is rotated. 66 is the sleeve base, 70 is the sleeve rate,
69 is a bearing. A polishing holder 71 presses the lens L against the polishing pad 68. The pressure is applied by a holder shaft 73 via a pressure spring 72. In addition.

74 is a metal, and 75 is an abrasive drain pin. Next, to explain the swinging motion of the polishing plate with reference to FIG. In the case of Niri, the swinging base can always be lifted with the same force regardless of the extended stroke of the rod. On the other hand, when the rocking is to decrease, it can be easily set by simply adjusting the discharge speed of the cylinder. In addition, in the case of an air cylinder, near the swing return point near 08 (Pl, 22 points centered on the PO point),
It acts as a residual air cushion within the cylinder tube, softening the shock and allowing a pendulum-like rocking motion to occur in an extremely natural state. In addition, in the case of a hydraulic cylinder, since it is mainly used for low-speed rocking, no shock occurs at all.

Reference numeral 83 denotes a first belt for conveying the workpiece W in which the lens L is housed by a belt conveyor. 84 and 85 are cylinders for dividing the workpiece toy W into pieces one by one. Next, the operations and their effects will be explained along with the flowchart in Figure (S). First, turn on the start switch of the precision grinding machine main body (B), and
is rotated to sequentially transport the workpiece toy W containing the lens L supplied from the lens supply section (A) to the loading position P. At this time, the cylinders 84 and 85 are operated to send the work wheels I and I to the loading position P one by one. That is, cylinder 84.
85 (when one is extended, the other is retracted), the belts are fed one by one, and when the workpiece toy W reaches the loading position 1iP, the first belt 83 is temporarily stopped. If the workpiece toy W is stopped at the loading position P in this way, the cylinder 7
7 and 79 (raise/lower and open/close), move the loading chuck 80 to the loading position P (where the workpiece toy W containing the lens L is placed), engage the workpiece toy W, and perform fine grinding. Transport it towards the machine body (B). In other words, ■ Stop the workpiece toy W at the loading position P, ■ Open the loading chuck 80 and lower it, and ■ Stop the workpiece toy W at the loading position P.
(2) The lens polishing mechanism of the fine grinding machine body (B) is conveyed to the lens polishing mechanism. Note that removal after polishing can be performed by performing the reverse operation. In this way, the lens L in the transported workpiece toy W is polished in the lens polishing mechanism as described above.

FIGS. 4(A) and 4(B) show the polishing mechanism of the polishing machine body (C) of the automatic polishing apparatus of the present invention. Reference numeral 86 denotes the slide bed main body 1, which is equipped with a slide shaft 88 for downward movement by 1 L, in which a slide arm 89 is inserted into a slide base 87 for longitudinal movement. 81, the slide arm 88 is the slide shaft 88

This is a belt chute added via the belt chute 00, and a first belt 102 and a second belt 103 are wound around it.
Reference numeral 104 denotes a polishing tank, which is installed at the same position as the lens holder provided at the tip of the slide arm 88. In this way, the slide bed main body 1 moves back and forth between the slide shafts 93 by the expansion and contraction of the air cylinder 85, while the lens polishing holder (
The slide arm 88 equipped with a (not shown) is moved downwardly between the slide shafts 88 via the air cylinder 91.

By this vertical movement back and forth, each belt 102, 10

In this embodiment, one slide arm 89 is equipped with two lens polishing holders, but one slide arm 89 may be equipped with two or more, or several slide arms 88 may be equipped with one or several lens polishing holders. It is also possible. The lens polishing method and mechanism in the polishing machine main body (C) are the same as in the fine grinding machine main body (B) shown in FIG. In other words, it is included in Work Ya Toy W/

FIGS. 4(c) and 4(d) show a method for supplying and removing lenses by the apparatus shown in FIG. 4(a), and a flowchart thereof. The operation and effects will be explained step by step below. First, when lens-introduced workpieces W are sequentially supplied to the first belt 102'', the workpieces W are sequentially arranged in rows via the workpiece guide 105. Next, by the operation of the first gear 1-G1 and the second gear G2, the workpiece toy A of A is moved to the second belt 103, and the lens L is supplied and removed at the loading position PI of the lens polishing machine main body (C). can do. On the other hand, when the workpieces W supplied to the first belt 102 cannot be arranged on the workpiece guide 1051, they are moved to the front and are sequentially arranged on the workpiece guide 106. Therefore, as above, the first gate G3 and the second gate G3
By the operation of the gate G4, the work yatoy W is sequentially (C
,D) Transferred to the second belt 103 and rolling P2
The lens can be removed at this position. This loading position Pi, P2 is reached by the downward movement of the slide arm 89 shown in FIG. The lens L is moved up and back by 1 step and then lowered again to the position of a polishing plate (not shown) attached to the polishing tank 104, where the lens L is automatically polished. After polishing is completed, the lens L is ejected to the workpiece toy W by the above-mentioned reverse operation, and the lens L is removed together with the workpiece toy W. To explain this operation in more detail, the two wooden polishing holder shafts are provided with a carrier that can move the center of the main body back and forth, and which can also be moved up and down, so that the third polishing holder shaft can move freely up and down.
It is located above the belt 2, and when the workpiece toy W is positioned, it is lowered so that the lens L in the workpiece W can be attracted by the polishing holder. Next, the lens L is polished by raising and lowering it in this state. The polished lens L is stored in the work tray W at the loading position by the reverse operation described in 1.

The supply and removal of the lens through suction, polishing, and ejection are all automatically and interlocked.
