Are handled and processed as appropriate.

  In this manner, after stopping the glass plates Ga and Gb above the plate-like body support portion 41, the width receiving device 45 is operated. That is, in the case of the long glass plate Gb, the long cylinder device 49 is contracted by the control of the control unit 80 so that the long width receiving body 48 is brought into contact with or close to the side surface in the width direction of the long glass plate Gb. In the case of the short glass plate Ga, the short cylinder device 47 is contracted by the control of the control unit 80 so that the short width receiving body 46 is brought into contact with the side surface in the width direction of the short glass plate Ga or Close.

  As described above, with the glass plates Ga and Gb being stopped above the plate-like body support portion 41, the operator first presses the angle raising button 75 of the adjustment operation portion 74. Thereby, by the control via the control unit 80, the output shaft 52 can be normally driven by the forward / reverse drive motor 51, the rotation link body 53 can be normally rotated, and the push-pull link body 54 can be pushed upward. Accordingly, the swinging body 40 to which the push-pull link body 54 is connected is swung upward around the axis 39a. Then, the support surface 41a of the plate-like body support portion 41 is in an inclined posture in which the support surface 41a is located above the transport surface 1a. Therefore, as shown in FIG. 5, the glass plates Ga and Gb on the transport surface 1a are supported on the support surface. It is supported by 41a and lifted in an inclined manner. At this time, the inclination angle is determined by releasing the pressing operation of the angle increase button 75.

  When the maximum angle is reached, the tilt-side detector 69 is operated by the tilt-side cam body 68 to detect that the support surface 41a is in the tilted posture of the maximum angle, and accordingly, by control via the control unit 80. The driving of the forward / reverse drive motor 51 can be stopped, thereby preventing overrun.

  When lifting in such an inclined shape, the side surfaces in the width direction of the glass plates Ga and Gb can be received by the stepped receiving surfaces 46a and 48a of the both receiving members 46 and 48. By receiving the stepped receiving surfaces 46a and 48a, it is possible to prevent the postures of the glass plates Ga and Gb from being disturbed unexpectedly during tilting and swinging. In addition, when the width receiving bodies 46 and 48 are close to the side surfaces in the width direction of the glass plates Ga and Gb, the glass plates Ga and Gb on the support surface 41a are moved to the axis 39a side when lifted in the inclined shape described above. It slides and is received by the stepped receiving surfaces 46a and 48a.

  Next, the operator presses the up / down button 77 of the adjustment operation unit 74. As a result, under the control through the control unit 80, the upper cylinder device 35 is extended and the lifting body 36 and the swinging means 50 are integrally lifted, and as shown by the solid line in FIG. A certain rocking body 40, that is, the glass plates Ga and Gb can be raised. Then, after the upper cylinder device 35 is extended to the stroke end, the elevating and lowering button 77 is continuously operated to extend the lower cylinder device 33, and the elevating body 36 and the swinging means 50 are integrally raised. Therefore, as shown by the phantom line in FIG. 6, the rocking body 40 in the inclined posture, that is, the glass plates Ga and Gb can be further raised. At that time, the ascending position is determined by releasing the pushing operation of the up / down button 77.

  Thus, the glass plates Ga and Gb can be tilted and raised toward the visual inspection part A. At this time, the tilt angle and the raised position are most easily visually inspected according to the height of the operator. Can be adjusted. That is, the adjustment may be performed while the operator performs the above-described tilting operation or ascending operation, or may be performed by the final operation after roughly performing the above-described tilting operation or ascending operation. This final operation adjusts the rapid warming of the tilt angle by pressing the angle increase button 75 or the angle decrease button 76, and adjusts the vertical position by pressing the lift button 77 or the lift button 78. This is possible.

  In this way, after adjusting the tilt angle and the rising position so that the operator can easily visually inspect, the control unit 80 can store the tilt angle and the rising position by pressing the preset button 79. In this case, a suitable tilt angle can be grasped and stored based on the position of the detected portion 62 detected by the detector 63 of the swing angle detecting means 60.

  As described above, with the glass plates Ga and Gb at a tilt angle and a raised position suitable for the operator, the operator performs an intended visual inspection on the surfaces of the glass plates Ga and Gb. Then, it is determined whether the glass plates Ga and Gb are defective or non-defective, and the result operation unit 81 is operated based on the determination result. That is, when it is a non-defective product, the non-defective product button 82 is pressed, and when it is a non-defective product, the defective product button 83 is pressed. At the same time, an inspection end signal is input from the result operation unit 81 to the control unit 80, and thus the glass plates Ga and Gb are moved onto the transport path 1 by the reverse operation as described above by the control via the control unit 80. return.

  That is, by the control via the control unit 80, the lower cylinder device 33 and the upper cylinder device 35 are contracted to lower the lifting body 36 and the swinging means 50 integrally, and as shown in FIG. The rocking body 40 in the inclined posture, that is, the glass plates Ga and Gb is lowered. Then, the output shaft 52 can be reversely driven by the forward / reverse drive motor 51 to reversely rotate the rotary link body 53 to move the push-pull link body 54 downward, so that the push-pull link body 54 is connected. The oscillating body 40 is oscillated downward around the axis 39a.

  Then, the support surface 41a of the plate-like body support portion 41 is in a horizontal posture positioned below the transport surface 1a, so that the glass plates Ga and Gb on the support surface 41a are transported as shown in FIG. It can be supported by the surface 1a and returned onto the transport path 1. The rotation position of the rotation link body 53 can be controlled by the swing control means 65 when the horizontal cam body 66 operates the horizontal detector 67.

  Before and after this, both cylinder devices 47 and 49 of the width receiving device 45 are extended to move both width receiving bodies 46 and 48 outward and away from the side surfaces of the glass plates Ga and Gb. After that, the glass plates Ga and Gb can be carried out to the conveying device 4 side by driving the driving unit 24 of the rotation driving unit 20 in the conveying device 10A.

  As described above, the visual inspection of the glass plates Ga and Gb is finished in the plate-like body inspection facility 30A, and the next glass plates Ga and Gb are subsequently carried from the transfer device 2 to the transfer device 10A. At that time, the tilting and rising movements of the next glass plates Ga and Gb are automatically stored by the control from the control unit 80 based on the data because the previous operation is stored in the control unit 80. Done. That is, the intended visual inspection can be performed as the tilt angle and the raised position in the state where the visual inspection is most easily performed for the same worker.

  In addition, when the worker is changed, the tilt and rise are automatically performed by the control from the control unit 80 based on the stored data, and then the changed worker performs the final operation as described above. Thus, the inclination angle and the ascending position are adjusted so as to be most easily visually inspected. Then, by pressing the preset button 79, the corrected inclination angle and the raised position can be stored in the control unit 80.

  In the above-described embodiment, the rocking body 40 is tilted and then lifted, but this changes the operation sequence in the adjustment operation unit 74 and raises the rocking body 40 by the elevating means 31 to raise the glass plate Ga. , Gb can be lifted and supported, and even if the swinging body 40 is tilted by the swinging means 50, the intended visual inspection can be performed in the same manner as the tilt angle and the raised position so that the operator can easily perform the visual inspection. become.
