用されつつある。 Conventionally, the chucking device for a sling machine has been a screw-driven lens holder shaft that is manually tightened to chuck the eyeglass lens held on the lens holding shaft, and a lens holder that is used to eliminate the hassle of manual operation. There are known devices in which the shaft is controlled by a motor. Among these devices, the device in which the lens holding shaft is controlled by a motor is called an electric chuck device, and because it is easy to handle, it is being used as a result of the automation of ball-sliding machines.

はなかつた。 By the way, when chucking eyeglass lenses, the worker usually supports the eyeglass lenses held by the lens holding shaft with his/her hands until chucking is completed. This is to prevent the spectacle lens from falling off or being tilted and chucked before being held between the lens holding shaft and the lens pressing shaft. However, with automatic chucking devices, if the eyeglass lenses are attached at an angle, it is cumbersome to restart chucking (the motor needs to be reversed), and it is easy to accidentally pinch your fingers with too much force. In some cases, the operability was not always satisfactory.

チヤツキング装置を提供することにある。 The present invention aims to eliminate the drawbacks of the above-mentioned conventional technology, namely, to provide an electric chuck device that can easily reset the eyeglass lenses even when they are set at an angle, and that can firmly position the eyeglass lenses after the tilt is corrected. It is about providing.

る。 A detection device is provided between the intermediate member 3 and the moving member 5 to detect their relative movement. That is, in this embodiment, as shown in FIG. 2, which is a view in the direction of arrow A in FIG. A photo sensor 11 having a section is provided respectively. In the photo sensor 11, when the intermediate member 3 and the movable member 5 are in the positional relationship as shown in FIG. Even if the moving member 2 cannot move to the left in FIG.
When the movable member 5 is moved relative to the intermediate member 3 by being pressed further than the state shown in the figure, the light emitted from the light emitting section is prevented from entering the light receiving section.
Therefore, the output signal of the photo sensor 11 is high level in the former case, and low level in the latter case.

９の回転を制御する。 A control block diagram of the motor 9 is shown in FIG. The operation unit 12 has a temporary fixing button 12a, a permanent fixing designation button 12b, and a release designation button 12c,
A signal is input to the control unit 13 when each button is pressed. Signals from the photo sensor 11 are also input to the control unit 13, and control signals are input from these four signals to the motor drive circuit 14 to control the rotation of the motor 9.

なるとモータ９を停止する。 When the temporary fixing designation button 12a is pressed, the control unit 13 inputs a control signal to the motor drive circuit 14 to rotate the motor 9 in the forward direction as long as a high level signal is input from the photo sensor 11.
When a low level signal is input from the photo sensor 11, the motor 9 is stopped. Next, when the final stop designation button 12b is pressed, a control signal for causing the motor 9 to rotate forward again is input to the motor drive circuit 14, and when the motor 9 rotates by a predetermined amount, the rotation of the motor 9 is stopped. Then, when the release designation button 12c is pressed, the control section 13 inputs a signal for reversing the motor 9 to the motor drive circuit 14, and when the signal from the photo sensor 11 becomes high level, the motor 9 is stopped.

いように構成することができる。 Of the designation buttons 12a, 12b, and 12c, only the temporary fixation designation button 12a is provided on the operating section 12, and the final fixation is performed by a switch that detects the lowering of the head frame of the milling machine. The release may be performed by a switch that detects the rise of the frame. In other words, temporary fixing, final fixing, and release may be performed automatically instead of manually. At this time, it can be configured so that the release does not occur during processing.

うなことはない。 Since this embodiment has such a configuration, when the attachment member fixed to the unprocessed eyeglass lens is inserted into the holding hole 1a of the lens holding shaft 1 and the temporary fixation designation button 12a of the operation section 12 is pressed, the motor 9 is activated. The pinion 7 rotates in the forward direction, the rack 5c moves, and the movable member 5 presses against the lens holding shaft 2 via the spring 4.
move in a direction so as to sandwich the eyeglass lenses (to the left in Figure 1). When the lens presser rubber 2a of the lens presser shaft 2 comes into contact with the spectacle lens, the lens presser shafts 2 and 2 and the intermediate member 3 cannot move any further. begins to move. As a result, the photo sensor 11 and the reflector 10 no longer face each other, so the signal from the photo sensor 11 changes from a high level to a low level, and the motor 9 stops. This completes the temporary fixing. In this state, it is possible to move the lens holding shaft 2 against the spring 4 in the direction opposite to the pressing direction (to the right in Figure 1), so if the spectacle lens is attached at an angle, it can be moved. , the inclination can be corrected by removing the contact between the spectacle lens and the lens holding shaft 2. In addition, even if your finger is accidentally pinched, there is no possibility of injury because the lens holding shaft 2 is only pressed by the force of the spring 4 and no large pressing force is applied when the lens is temporarily fixed. do not have.

チヤツキングが完了する。 Next, when the final stop designation button 12b is pressed, the motor 9 further rotates (forward rotation), the movable member 5 moves relative to the intermediate member 3 via the pinion 7, the spring 4 is compressed, and the inside of the disc 5b is moved. When the side surface comes into contact with the other end of the intermediate member 3 and the intermediate member 3 is held between the lens holding shaft 2 and the moving member 5, the lens holding shaft 2, the intermediate member 3, and the moving member 5 become one body. When the motor 9 stops rotating a predetermined amount from the temporarily fixed state, the lens press shaft 2 presses the spectacle lens with a predetermined pressing force. This completes the chatting for the final stop.

れることとなる。 When the eyeglass lens processing is completed and the release designation button 12c is pressed, the motor 9 rotates in the opposite direction, the lens holding shaft 2 returns to the initial position shown in the figure via the pinion 7, the moving member 5, etc., and the photo sensor 11 presses the reflector 1.
0 and outputs a high level signal, so the motor 9 stops. This causes the chatting to be canceled.
