In response to the weight provided and to be automatically adjusted by the variable means (9).

At this time, the head weight detecting means 7 is installed at the bottom of the plate holder 6 to detect the weight of the head 4, and the control means 8 responds to the output signal of the head weight detecting means 7. The weight providing and variable means 9 are controlled, and the weight providing and variable means 9 are installed to be connected to the fixed bar 41 of the head 4 in response to the output signal of the control means 8. The weight applied to the head 4 is varied so that the weight applied to the template 61 is changed to the added or subtracted form.

On the other hand, Figures 2 to 4 show a first embodiment of the present invention, the head weight detection means 7, the template detection port (sliding) to slide on the template 61 to rotate with the fixing bar 41 ( 71 is provided, and the lower and lower bars 72 and the load cell 73 are successively provided at the bottom of the template detection port 71.

Therefore, the template detecting port 71 transmits the pressure applied in response to the change in the sliding position with the template 61 to the load cell 73 through the elevating bar 72 so that the template is sensed by the load cell 73. The weight of the head 4 applied through the earth 71 can be detected by an electrical signal and transmitted to the control means 8.

In addition, the control means 8 for controlling the weight providing and the variable means 9 in response to the output signal of the head weight detecting means 7 having the above configuration includes an indicator 81, a relay 83, and It consists of a motor drive part 82.

At this time, the indicator 81 generates a control signal corresponding to the output signal of the load cell 73 to the relay 83, and the relay 83 is on / off in response to the output signal of the indicator 81 It is operated to supply power voltage to the upper and lower position sensors 95, 96 and the variable weight motor 93 of the weight providing and variable means 9, the motor drive 82 is the main switch 85 ) And the weight varying motor 93 in the forward direction according to the state of the reset switch 86 and the upper and lower position detection sensors 95 and 96 and the supply direction of the power voltage supplied through the relay 83. Or drive in reverse direction.

In addition, the first embodiment as the weight providing and variable means 9, the weight 91 and the base plate 92, the motor for variable weight 93, the lifting device 94 and the upper and lower positions It consists of sensors 95 and 96.

In the above, the weight 91 can be moved up and down on a pair of guide rods 97, one end of which is fixed to the head 4 fixing bar 41 and the other end of which is provided with a buffer spring 911 and a fixture 912. It is installed so as to apply a weight to the head fixing bar 41 in response to the positional change of the template 61, the base plate 92 is fixed to the rear bottom of the body (1) variable weight motor ( The pair of polishing rods 99 for supporting the 93 and the elevating movable tool 94 are fixedly installed, and the power of the variable weight motor 93 is transmitted to the elevating movable tool 94. The screwed shaft 98 is configured to be moistened.

In addition, the variable weight motor 93 is fixedly installed on the base plate 92 and operated in response to a signal output from the motor driving unit 82 of the control means 8, thereby allowing the screw type through the timing belt 931. The shaft 98 is rotated to allow the elevating movable tool 94 to elevate the weight 91, and the elevating movable tool 94 has guide holes 941 formed at both sides of the polishing rods 99. The bolt fastening hole 942, which is axially movable to move up and down, has a configuration in which a screw shaft 98 is coupled and is clockwise or counterclockwise in response to the driving direction of the variable weight motor 93. The lifting and lowering according to the rotation direction of the screw-type shaft 98 is rotated, and the weight 91 is raised or lowered to change the weight of the rear portion of the head 4.

In addition, the upper and lower position sensors 95, 96 are respectively installed on the upper and lower portions of the support 100 is installed vertically on one side of the base plate 92, the elevating movement of the elevating moving device 94 And the upper and lower limit positions according to the falling and transmitted to the control means (8).

At this time, the guide rod 97 is rotatably installed in the front and rear direction to the fixed bar 41 of the head 4 through the rotation hole 411 is coupled to the guide rod 97 and the lifting up and down The weight 91 is the weight regardless of the position of the fixed rod (3) by the rotation of the rotating hole 411 is rotated in response to the position change of the fixed bar 41 changes in accordance with the rotation of the head (4) The weight of the weight 91 maintains the vertical state.

In addition, in the vertical direction of the front and rear surfaces of the weight 91, an insertion hole 911 into which a part of the guide rod 97 is inserted, a buffer spring 971, and a fastener 972 are fitted into the weight 91 to move up and down. Since the guide groove 912 is formed and punched salmon up and down with respect to the vertical direction, the weight 91 is subjected to the elastic force of the buffer spring 971 located in the guide groove 912 and guide rod 97 It can be moved up and down smoothly.

According to the first embodiment of the present invention having such a configuration, first, the indicator (81) in the control means (8) is applied to the template (61) through the load cell (73) of the head weight detection means (7). If the load of the head 4 transmitted through the load cell 73 via the template 61 and the template detection port 71 sliding thereto is not detected, the indicator 81 It connects high output terminal (HIGH) and common terminal (COM).

Accordingly, since the relay 83 is driven so that the contact terminals A1-A2 and B1-B2 are connected to each other, the motor 93 provides the weight and the variable motor 93 of the variable means 9 in the motor driving unit 82. Since the forward rotation of the screw-shaped shaft 98 is connected by the timing belt (931) and the forward and lowering movement hole 94 is moved along the polishing rod 99, so that the weight (91) In response to the lifting of the movable tool 94, the lifting and lowering is performed along the guide rod 97 so that the weight of the weight 91 is not applied at all on the head 4, and only its own weight is applied.

As such, the elevating movable tool 94, which is elevated along the polishing rod 99 in response to the forward rotation of the variable weight motor 93, is maintained until it contacts the upper limit position sensor 95 on its upper surface. As described above, when the upper surface of the elevating movement port 94 contacts the upper limit position sensor 95, the motor driving unit 82 blocks driving of the variable motor 93.

In such a state, when the template 61 is fixedly installed on the template fixture 6 and the lens is processed, the load of the head applied to the template 61 rotated in response to the machining position and the amount of the lens is applied to the template ( Since it is transmitted to the load cell 73 through the template detection port 71 having a shape sliding to 61 it is possible to detect the load of the head (4) in the load cell (73).

In this way, when the load cell 73 detects the load of the head 4 changed during the machining of the lens, the indicator 81 in the control means 8 connected thereto is compared with the load value already stored in itself.

As a result, when the load of the head 4 detected through the load cell 73 rises above a predetermined value, the indicator 81 connects its low output terminal LOW and the common terminal COM.

Therefore, since the contact terminals A1-A3 and B1-B3 of the relay 83 controlled by the indicator 81 are connected to each other, the motor driver 82 reversely rotates the variable motor 93. Since the screw shaft 98 connected by the timing belt 931 is reversely rotated so that the elevating movable tool 94 descends along the polishing rod 99, the weight 91 is the elevating movable tool 94. In response to the lowering of)) is lowered along the guide rod (97).

Therefore, the weight 91 has a medallion shape on the fixing bar 41 installed at the rear of the head 4, and the weight applied to the front part of the head 4 is the weight of the weight 91. Since it can be reduced as much as possible, it is possible to prevent the temporary assembly lens from being deformed due to the excessive load of the head, thereby eliminating processing errors.

Of course, the elevating movable tool 94 descending along the polishing rod 99 in response to the reverse rotation of the variable weight motor 93 has the lower surface thereof in contact with the lower limit position sensor 96. Since the driving unit 82 blocks the driving of the variable weight motor 93, further fall is prevented.

On the other hand, the main switch 85 provided in the control means 8 of the first embodiment of the present invention performs a function of controlling the power supply voltage supplied to the apparatus of the present invention as a whole, and the reset switch 86 The lifting port 94 is installed to return to the original position (ie, the lowest end position of the polishing rod 99) regardless of the current position.

5 and 6 show a second embodiment of the present invention, since the head weight detecting means 7 has the same configuration as that of the first embodiment, detailed descriptions will be omitted in order to avoid redundant description. When described with reference to the control means (8) and the weight providing and the variable means (9) as follows.

The control means 8 in the second embodiment of the present invention is composed of an indicator 81 and a timing relay 87. The indicator 81 responds to the output signal of the load cell 73 as described above. A control signal is generated to the timing relay 87, which responds to the output signal of the indicator 81 to the solenoid 101 of the weight providing and variable means 9 for a time set therein. It will supply power.

In addition, the weight providing and variable means (9) is elastically installed between the fixing bar 41 of the head (4) 41 and the rod (101a) of the solenoid 101 to change the position of the template 61 In response to the tension force to be applied to the head fixing bar 41 side, and the solenoid 101 is fixed to the back of the body (1) by the timing relay 87 of the control means (8) When the power supply voltage was supplied for a predetermined time, the spring 103 was pulled to change the weight of the rear part of the head 4.

In the indicator 81 of the control means 8 having such a configuration, the driving of the timing relay 87 is interrupted when the load of the head 4 detected through the load cell 73 is less than the load value set in itself. Let it be.

However, when the load of the head 4 applied through the template 61, the plate sensing hole 71, and the load cell 73 due to the processing of the lens is more than the reference value, the indicator 81 and its low output terminal (LOW) and Since the joint terminal COM is connected, the timing relay 87 operates for a predetermined time (for example, 0.5 seconds), so that the spring 103 having one end fixed to the rod 101a of the timing relay 87 is As a result of the expansion, a portion of the head 4 is pulled downward so that the fixed bar 41 of the head 4 descends in response to the tensile force and the falling amount of the spring 103 so that the weight is applied to the front part of the head 4. This reduces the load on the temporary lens, thereby eliminating the machining error.

7 and 8 show a third embodiment of the present invention, the head weight detecting means 7 has the same configuration as that of the first and second embodiments, so that detailed description will be made in order to avoid overlapping descriptions. Omit.

The control means 8 in the third embodiment of the present invention is composed of an indicator 81 and a timing relay 87. The indicator 81 responds to the output signal of the load cell 73 as described above. The control signal is generated in the timing relay 87, which responds to the output signal of the indicator 81 and provides the weight and the linear motor 104 of the variable means 9 for a time set therein. It will supply power.

In addition, the weight providing and the variable means (9) is installed elastically the spring 103 between the fixed bar 41 of the head 4 and the wheel 104a of the linear motor 104, the position of the template 61 In response to the change, a weight can be applied to the head fixing bar 41 through the tension force, and a linear motor 104 is fixedly installed on the rear surface of the body 1 so that the timing relay of the control means 8 87) when the power supply voltage is supplied for a predetermined time, the spring 103 is wound to change the weight of the rear part of the head 4.

In the indicator 81 of the control means 8 having such a configuration, when the load of the head 4 detected through the load cell 73 is less than the load value set in itself, the high output terminal LOW and the common terminal (COM) is connected for a predetermined time so that the linear motor 104 is driven in the forward direction to maintain the spring 103 is in a contracted state so that its own weight generated from the front of the head (4) to the temporary assembly lens To be delivered as is.

However, when the load of the head 4 applied through the template 61, the template detector 71, and the load cell 73 due to the processing of the lens is greater than or equal to the reference value, the indicator 81 has its low output terminal LOW. And the common terminal COM are connected to each other, the timing relay 87 operates for a predetermined time, so that the linear motor 104 is driven in the reverse direction for a predetermined time. It is wound around the wheel 104a.

Therefore, the spring 103 installed between the fixed bar 41 of the head 4 and the wheel 104a of the linear motor 104 is expanded, so that the fixed bar 41 of the head 4 is moved to the spring. Since it descends in response to the tensile force and the winding amount of (103), the weight applied to the front portion of the head 4 is reduced by that much can reduce the load on the temporary assembly lens, thereby reducing the processing error.

On the other hand, Figure 9 is a block configuration according to a fourth embodiment of the present invention, Figure 10 (a) (b) is a mechanical configuration of the head weight detection means 7 according to the fourth embodiment of the present invention, The head weight detection means (7) is installed in the plate detection port 71 so as to slide on the template 61 to rotate with the fixed bar 41 as shown in Figure 10 (a) changes the position of the template 61 In response to this, the template detecting hole 71 changes the position of the elevating bar 72. The operation lever 721 is provided at the elevating bar 72, and the limit switch 74 is provided at the bottom thereof. In response to the position change of the elevating bar 72 which is moved up and down with the template detecting port 71, the operation lever 721 turns on / off the limit switch 74 to drive the relay 83. To determine the direction.

In addition, the head weight detection means (7) is a template detection port 71 in the upper end of the elevating bar 72 to be slid to the template 61 to rotate with the fixed bar 41, as shown in Figure 10 (b) In order to change the position of the elevating bar 72 in response to the positional change of the template 61, the lower end of the elevating bar 72, the movable plate 751 and the fixed plate ( 752) is installed, and the spring 76 and the guide bar 77 between the movable plate 751 and the fixed plate 752 of the operating port 75 and at the same time the die The relay 83 is driven by installing a limit switch 74 that is turned on and off by an operation port 75 driven in response to a position change of the elevating bar 72 that moves up and down with the earth 71. The direction was decided.

Further, according to the fourth embodiment of the present invention according to the control means 8, the indicator 81 generates a control signal to the relay 83 in response to the state of the limit switch 74 and the relay 83 ) Is operated on / off in response to the output signal of the indicator 81 to provide the upper and lower position sensors 95 and 96 and the weight of the weight providing and variable means 9 mentioned in the first embodiment. The supply direction of the power supply voltage supplied to the motor 93 is determined. In the motor driver 82, the states of the main switch 85, the reset switch 86, and the upper and lower position detection sensors 95 and 96 are used. And the weight variable motor 93 installed in the fixed bar 41 of the head 4 by driving the variable weight motor 93 in the forward or reverse direction according to the supply direction of the power voltage supplied through the relay 83. It has a configuration to automatically vary the load of the head 4 through the weight change.

In the indicator 81 in the control means 8 in the fourth embodiment having such a configuration, the head 4 applied to the template 61 via the limit switch 74 of the head weight detection means 7 is provided. If the weight is detected and the limit switch 74 remains "off" because the load of the head 4 is not applied to the template 61, the indicator 81 is connected to the high output terminal HIGH and the common terminal (HIGH). COM).

Accordingly, since the relay 83 is driven so that the contact terminals A1-A2 and B1-B2 are connected to each other, the motor 93 provides the weight and the variable motor 93 of the variable means 9 in the motor driving unit 82. Since the forward rotation of the screw-shaped shaft 98 is connected by the timing belt (931) and the forward and lowering movement hole 94 is moved along the polishing rod 99, so that the weight (91) In response to the lifting of the movable tool 94, the lifting and lowering is performed along the guide rod 97 so that the weight of the weight 91 is not applied at all on the head 4, and only its own weight is applied.

In this state, the lens processing is performed, so that the load of the head applied to the template 61 becomes a predetermined value or more, so that the operating lever 721 or the elevating bar 72 of the elevating bar 72 connected to the template detecting port 71 is performed. (72) When the limit switch 74 provided between the operation holes 75 of the lower end is "on", the indicator 81 connects its low output terminal LOW and the common terminal COM.

Therefore, since the contact terminals A1-A3 and B1-B3 of the relay 83 controlled by the indicator 81 are connected to each other, the motor driver 82 reversely rotates the variable motor 93. Since the screw shaft 98 connected by the timing belt 931 is reversely rotated so that the elevating movable tool 94 descends along the polishing rod 99, the weight 91 is the elevating movable tool 94. In response to the lowering of)) is lowered along the guide rod (97).

Therefore, the weight 91 has a medallion shape on the fixing bar 41 installed at the rear of the head 4, and the weight applied to the front part of the head 4 is the weight of the weight 91. Since it can be reduced as much as possible, it is possible to prevent the temporary assembly lens from being deformed due to the excessive load of the head, thereby eliminating processing errors.

Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described above, according to the present invention, by providing a weight control unit and a variable stage, the control unit for automatically controlling the lenses with the shape, form, and size of the glasses frame selected by the user is provided. The weight of the head corresponds to the position of the demonstration lens so that the weight is automatically adjusted by the weight provision and variable means, thereby eliminating the processing error due to the deformation of the temporary assembly lens generated when the lens is processed using the thin demonstration lens. Of course, it is possible to improve the productivity by reducing the process and working time, in particular, it is a very useful invention, such as can be precisely processed to match the optical axis or focus of the lens and the reliability of the lens processing.
