In addition, the support frame (7) has a sensor unit formed on the top and the vertical transfer device for selectively vertically transferring the transfer rod 60 for horizontal transfer along the transfer path groove (15) formed in the drip tray 14 is combined Is done.

The present invention uses the data transmitted by a separate spectacle frame shaper without the hassle of attaching and detaching the template to the spectacle lens processing machine (M) to process the spectacle lens quickly and precisely, as well as the failure rate and product due to leakage. It is a characteristic gist of the design to additionally incorporate a technical configuration that can drastically improve a defective rate.

The present invention for achieving the characteristic gist is a vertical transfer means 20 for vertically moving the lift guide 26 by the distance displacement according to the rotation angle input to the step motor 24 in the front of the main body (1) Is placed.

That is, the vertical conveying means 20 of the present invention is not installed at the lower part of the conveying path groove 15, which is a path for transporting the conveying rod 60, and the front side of the main body 1 spaced apart by the predetermined distance from the conveying way groove 15. Since it is installed in the transport cabinet groove (15) to maintain the isolation state even if the water flows through the transport groove 15, the water does not get on the screw shaft (22) due to the leakage is less trouble, almost no malfunction This can increase the completeness of.

The vertical conveying means 20 is a fixed plate 21 is installed on the inner front side base frame (1a) of the main body 1, the screw shaft 22 is rotatably mounted in the fixed plate 21. Since the screw shaft 22 is rotated by the bearing 23, the screw shaft 22 is smoothly rotated. The screw shaft 22 is connected to the step motor 24 and the timing belt 25 to selectively receive the rotational force of the step motor 24. Will rotate.

The screw shaft 22 includes a lift guide 26 for vertically moving according to the rotation of the screw shaft 22 to lift and lower the feed rod 60 by a distance displacement according to the rotation angle input to the step motor 24. When screwed together, the lift guide 26 is guided by a pair of guide rods 27 mounted on the fixing plate 21 when the lift guide 26 is lifted and lowered smoothly in the vertical direction without flow to the left and right. It becomes possible.

One side of the lift guide 26 is provided with a transport block 30 is interlocked in the vertical direction in accordance with the vertical movement of the lift guide 26.

The transport block 30 has a support roller 31 rotatably installed at one side thereof, and the support roller 31 is transport rail 26a in a state in which the support roller 31 is seated on the transport rail 26a installed at one side of the lift guide 26. Riding smoothly in the horizontal direction, as well as can be linked with the lift guide 26 in the vertical direction in accordance with the driving of the lift guide (26).

The sensing block 40 is rotatably installed at the upper portion of the transfer block 30. The sensing block 40 has a rotating part 41 formed on one side thereof is coupled to the transfer block 30 and the hinge shaft 42 can be rotated around the hinge shaft 42, the other of the rotating part 41 On the side, the transfer block 30 and the spring 43 are coalesced to maintain a constant tension of the sensing block 40.

In addition, a pair of close contact sensors 50 are installed on the sensing block 40 and the transfer block 30 in the vicinity of the spring 43 so as to face each other.

Therefore, when the spectacle lens is processed by a distance displacement according to a certain rotation angle, the sensing block 40 is rotated about the hinge axis 42 while the close contact sensor 50 is in close contact with the spectacle lens 9 is rotated by a predetermined angle. The lift guide 26 automatically adjusts the distance displacement while the lift guide 26 moves up or down by the distance displacement according to the rotated rotation angle. At this time, the rotated sensing block 40 is restored to its original state by the restoring force of the spring 43.

A transfer rod 60 is installed at one side of the sensing block 40, and the transfer rod 60 penetrates the transfer end groove 15 formed at the support end 7a and the drip tray 14 at the tip of the support frame 7. The pressing plate 61 is installed at the upper end, and the lower end penetrates through the sensing block 40 and protrudes downward, thereby extrapolating the spring 43 providing the restoring force to the sensing block 40 at the protrusion 43. It will also serve to prevent deviations.

And a pair of guide rods 70 for guiding the transfer of the transfer rod 60 when moving up and down, the one side is fixed to the support end (7a) to both sides of the transfer rod 60 as shown in Figure 7 By being installed through the sensing block 40 and the transfer block 30, the sensing rod 40, the sensing block 40, the transfer block 30 can be raised and lowered more smoothly.

On the other hand, according to the present invention, while the spectacle lens is processed without using a template, the plate holder for fixing the template is not installed on the horizontal transfer table 6, while the rotation angle is provided on one side of the horizontal transfer table 6. Detection rod 80 is installed to detect the distance displacement according.

That is, the sensing rod 80 is moved up and down by the distance displacement according to the rotation angle input to the step motor 24 of the vertical transfer means 20 as the sensor lens is transported downward while processing the spectacle lens at a constant rotation angle state. It serves to press the pressing plate 61 of the rod 60, so that no further processing is made in the rotation angle state to move to the next rotation angle so that the continuous processing of the spectacle lens can be continued.

In addition, the present invention is a support roller (7b) at the tip of the support end portion (7a) so that the support frame (7), the sensing block 40, the transfer block 30 and the like can be transferred more smoothly in the horizontal direction. Is installed and the support roller 7b smoothly transports the guide groove 7d formed in the support 7c attached to the main frame and simultaneously prevents the support frame 7 from falling down.

It will be described the operating state of the subject innovation made in this configuration.

First, the data is processed by measuring the distance displacement (L) according to the rotation angle (0 ° ~ 360 °) of the frame rim of the frame to be processed (peripheral portion into which the eyeglass lens is fitted) using a separate frame measuring device. Is transmitted to the spectacle lens processing machine M of the present invention.

The transmitted data includes a step motor installed inside the horizontal carriage 6 to rotate the chuck 10 to which the spectacle lens 9 is fixed, and a vertical transfer means 20 for vertically transferring the lift guide 26. By being input to the step motor 24, the distance displacement of the lift guide 26 according to the rotation angle of the spectacle lens 9 is automatically adjusted according to the data.

That is, when a constant rotational angle is input to the stepper motor of the horizontal feeder 6, the distance displacement corresponding to the rotational angle is input to the stepper motor 24 of the vertical transfer means 20, so that the lift guide 26 is as much as the distance displacement. Ascending and descending, the transfer block 30 is interlocked by the lift guide 26, the transfer rod 60 is positioned at a constant height.

Therefore, as the eyeglass lens 9 is processed, the horizontal transfer table 6 is automatically lowered, and at this time, the sensing rod 80 presses the grounded pressing plate 61 to rotate the sensing block 40 while the close sensor 50 is rotated. Is in close contact.

When the contact sensor 50 is in close contact with the eyeglass lens as the distance displacement according to the corresponding rotation angle is completed, no further processing is performed, and the eyeglass lens automatically rotates by a predetermined angle and at the same time according to the rotated rotation angle. The transfer rod 60 is moved up and down as much as the distance displacement, and is positioned at an appropriate height, and thus continuous processing is repeatedly performed, thereby rapidly processing the precision spectacle lens.

On the other hand, as the sensing rod 80 is grounded to the pressing plate 61 while turning, it is preferable that rolling members 81 such as bearings are installed to reduce frictional noise and resistance generated when grounding.

The present invention receives the data processed by measuring the distance displacement (L) according to the rotation angle (0 ° ~ 360 °) using a separate spectacle frame shape measurer without the hassle of removing the template as in the prior art It is possible to quickly and precisely process the spectacle lens instantly while automatically adjusting the distance displacement according to the rotation angle.

In addition, by maintaining the watertightness of the vertical transport means for adjusting the distance displacement it is possible to improve the quality of the product by dramatically improving the failure rate and defective processing rate due to malfunction.
