  For example, in patent document 1, the processing position provided with the glass plate support part which supports a glass plate is arrange | positioned at intervals, and conveyance of the glass plate which moves a glass plate to a glass plate support part of each processing position in order. The device is mounted on a moving base that reciprocates between the glass plate support portions at each processing position, and a lift device that corresponds to the glass plate support portion at each processing position and that includes an air cylinder device. The glass plate is transported forward to the glass plate support at each processing position by reciprocating the moving table, raising and lowering the suction pad by the air cylinder device, and suctioning or releasing the glass plate of the suction pad. It is like that. In particular, the air cylinder device is configured to raise and lower the suction pad, and then lift and lower the glass plate by turning on and off the compressed air.

  By the way, in such a glass plate processing apparatus, since the suction pad is moved up and down by the air cylinder device, the lifting position and the lifting speed of the suction pad cannot be controlled.

  For this reason, the suction pad must always move up and down the entire stroke of the air cylinder device during the delivery of the glass plate on the support base at each processing position. For this reason, when the glass plate is delivered, it takes time to raise and lower the suction pad.

  Furthermore, since each suction pad receives the glass plate and transports it to the next processing position, it must be started after waiting for completion of the lift due to the full stroke contraction of the air cylinder device that lifts the suction pad. Cost.

  Due to the above, it takes time to transport the glass plate from the processing position to the processing position, and it cannot be expected to speed up the production of the processed glass plate.

  Therefore, the present invention has been made in view of the defects of the conventional glass plate processing apparatus described above, and the object is to speed up the conveyance of the glass plate from the processing position to the processing position, and to perform the processing operation. An object of the present invention is to provide a glass plate processing apparatus that can speed up the tact and further improve the production of the processed glass plate.

  In the present invention, a processing position having a glass plate support portion for supporting a glass plate is disposed at intervals, and the glass plate is conveyed from the glass plate support portion at one processing position to the glass plate support portion at the other processing position. A transport device, and the transport device reciprocates between the glass plate support portion at one processing position and the glass plate support portion at the other processing position; And a suction pad attached via an elevating device, and the reciprocating movement of the transport shuttle, elevating and lowering the adsorption pad by the elevating device, and adsorbing and releasing the glass plate of the adsorption pad. In the glass plate processing apparatus that transports the glass plate from one processing position to the other processing position, The slider consists of a slider crank mechanism, and a lift motor attached to the transport shuttle is connected to the crankshaft. A glass plate suction pad is attached to the slider, and the suction pad is raised and lowered by the rotation of the lift motor. It is a glass plate processing apparatus. Moreover, this invention is a glass plate processing apparatus which used the said raising / lowering motor as the servomotor numerically controlled.

  Further, in the present invention, the lifting device comprises a slider crank mechanism, and is connected to a lift shaft that is attached to a transport shuttle and is numerically controlled to a crankshaft, and a suction pad for adsorbing a glass plate is attached to the slider. The suction pad is moved up and down by the rotation of the lifting motor. By simultaneously controlling the lifting and lowering servo motor and the transfer control motor, the suction pad is sucked during the transfer movement of the glass plate from one processing position. This is a glass plate processing apparatus in which the glass plate is moved up by putting and the glass plate is gradually lowered as it approaches the other processing position of the next glass plate transfer.

  Further, according to the present invention, the elevating device comprises a slider crank mechanism, is connected to a crankshaft attached to a transport shuttle, and is connected to a numerically controlled servo motor for raising and lowering, and a suction pad for adsorbing a glass plate is attached to the slider. The suction pad is moved up and down by the rotation of the lifting motor. By simultaneously controlling the lifting servo motor and the transfer control motor, the glass plate is transferred from one processing position. This is a glass plate processing apparatus in which the glass plate is gradually lowered by suction pad as it approaches the other processing position of the glass plate transfer.

  Since the slider crank mechanism converts the crank rotational movement by the motor into the lifting movement of the suction pad, it is not necessary to rotate the motor forward and backward each time the suction is lifted and lowered. It only needs to rotate in one direction. In the slider crank mechanism, the elevating speed V is V = 0 at the top dead center and the bottom dead center where the slider, that is, the suction pad is turned back. That is, the speed temporarily becomes 0 at the conversion position from the rising to the lowering of the suction pad and the conversion position from the lowering to the rising. Then, deceleration to this speed V = 0 (deceleration curve) and acceleration (acceleration curve) from this speed V = 0 are smooth. For this reason, the suction lifting of the glass plate and the lowering of the suction glass plate to the processing position support table can be performed softly. The operation state of the slider crank mechanism is repeated mechanically and identically.

  In particular, the position of the bottom dead center of the lifting and lowering of the suction pad is adjusted to be close to the upper surface of the support base of the glass plate placement, so that the placement of the glass plate from the suction pad to the support base and the suction lifting of the glass plate are performed reliably. .

  In addition, by using a numerically controlled servo motor for the crankshaft, and thus the lifting motor that rotationally drives the crank, if this lifting servomotor and the transport control motor for transport are simultaneously controlled, the glass plate is transported. While moving, the suction pad can be raised to raise the conveyance line height of the glass plate to collide with other objects, contact, avoidance, etc., and gradually move toward the next glass plate transfer processing position. When it is lowered and reaches the processing position for the next glass plate transfer, the suction pad can be accurately positioned at the height position of the minimum distance necessary for the glass plate transfer.

  In this processing position, the minimum distance is lowered, the glass plate is opened to the glass plate support, and passed. Next, the suction pad rises again to the required minimum distance in the sky, and at the same time, the return stroke starts in the sky. With the start of the return stroke, the empty suction pad is further raised and lowered as it approaches the original processing position, and when returning to the upper part of the glass plate support at the original processing position, the suction pad is moved to the glass plate support. It is possible to wait until the conveyance starts.

  For this reason, the time from the lifting of the glass plate to the completion of the suction lifting of the glass plate after the lifting time of the glass plate and the time from the lifting to the start of conveyance to the next processing position is shortened. Furthermore, the time until the start of conveyance of the received glass plate is also shortened.

  Therefore, the processing glass plate conveyance time is shortened, and the tact of the processing operation at the processing position is increased. Therefore, the production speed of the processed glass plate is greatly increased.

  According to the present invention, there is provided a glass plate processing method and glass capable of speeding up the conveyance of the glass plate from the processing position to the processing position, increasing the tact time of the processing operation, and further improving the production of the processed glass plate. A plate processing apparatus may be provided.
