  For example, in Patent Literature 1, a processing position provided with a glass plate supporting portion for supporting a glass plate is arranged at intervals, and the glass plate is transferred to the glass plate supporting portion at each processing position in a progressive manner. The equipment is mounted on a moving table that reciprocates above the glass plate support at each processing position, and is mounted on this moving table via a lifting device that corresponds to the glass plate support at each processing position and that includes an air cylinder device. And the suction pad is reciprocated, the suction pad is moved up and down by an air cylinder device, and the suction or release operation of the suction pad glass plate is performed to sequentially transport the glass plate to the glass plate support portion at each processing position. It has become. In particular, the air cylinder device raises and lowers the suction pad, and further lifts and lowers the glass plate by turning on and off compressed air.

  By the way, in such a glass sheet processing apparatus, since the suction pad is moved up and down by the air cylinder device, it is impossible to control the position of the suction pad and the speed at which the suction pad is moved up and down.

  For this reason, the suction pad must always move up and down the entire stroke of the air cylinder device when the glass plate is transferred on the support table at each processing position. Therefore, it takes time to move the suction pad up and down when transferring the glass plate.

  Furthermore, since each suction pad receives the glass plate and transports it to the next processing position, it must be started after the suction cylinder has been lifted by the full stroke contraction of the air cylinder device that raises the suction pad, which is a wasteful time. Cost.

  As described above, it takes time to transfer the glass sheet from the processing position to the processing position, and it is not possible to expect a speed-up in the production of the processed glass sheet.

  Therefore, the present invention has been made in view of the above-described defects of the conventional glass sheet processing apparatus, and an object thereof is to speed up the transfer of the glass sheet from the processing position to the processing position, thereby improving the processing operation. It is an object of the present invention to provide a glass sheet processing apparatus capable of increasing tact time and thereby further increasing the production of processed glass sheets.

  According to the present invention, a processing position having a glass plate supporting portion for supporting a glass plate is disposed at intervals, and the glass plate is transported from the glass plate supporting portion at one processing position to the glass plate supporting portion at the other processing position. A transfer shuttle which reciprocates between a position above the glass plate support at one processing position and a position above the glass plate support at the other processing position; and A suction pad corresponding to the glass plate supporting part of the above, and attached via a lifting device, the reciprocating movement of the transport shuttle, lifting and lowering of the suction pad by the lifting device, suction and release of the glass plate of the suction pad. In a glass sheet processing apparatus configured to transport a glass sheet from a processing position to another processing position, The device is composed of a slider crank mechanism, a lift motor attached to the transport shuttle is connected to the crankshaft, a suction pad for sucking a glass plate is attached to the slider, and the suction pad is raised and lowered by rotation of the lift motor. It is a glass plate processing device. Further, the present invention is a glass sheet processing apparatus in which the elevating motor is a servomotor that is numerically controlled.

  Further, according to the present invention, the elevating device comprises a slider crank mechanism, which is attached to the transport shuttle on the crankshaft, and which is connected to a servomotor for numerically controlled elevating and lowering, and a suction pad for sucking a glass plate is attached to the slider. The suction pad is raised and lowered by the rotation of the lifting motor, and the servo motor for lifting and lowering and the transport control motor for transport movement are simultaneously controlled, so that suction is performed during the transport of the glass sheet from one of the processing positions. This is a glass plate processing apparatus in which a glass plate is lifted by putting, and the glass plate is gradually lowered as approaching the other processing position of the next glass plate transfer.

  Further, according to the present invention, the elevating device comprises a slider crank mechanism, which is attached to the transport shuttle on the crankshaft, and which is connected to a servomotor for numerically controlled elevating 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 elevating motor, and by simultaneously controlling the elevating servomotor and the transport control motor of the transport movement, during the transport movement of the glass sheet from one processing position, This is a glass sheet processing apparatus in which a suction plate is used to gradually lower the glass sheet as it approaches the other processing position of the glass sheet transfer.

  In the slider crank mechanism, since the rotational motion of the crank by the motor is converted into the elevating motion of the suction pad, it is not necessary to rotate the motor forward or backward every time the suction is raised or lowered. It only needs to rotate in one direction. Further, in the slider crank mechanism, the lifting speed V becomes V = 0 at the top dead center and the bottom dead center where the slider, that is, the suction pad is folded back. That is, the speed temporarily becomes 0 at the position where the suction pad is changed from rising to lowering and at the position where the suction pad is changed from lowering to rising. Then, deceleration to this speed V = 0 (deceleration curve) and acceleration from this speed V = 0 (acceleration curve) are smooth. Therefore, the suction lifting of the glass plate and the lowering of the suction glass plate on the processing position support table can be performed softly. The operation state of the slider crank mechanism is mechanically and identically repeated.

  In particular, by setting the position of the bottom dead center of the lifting and lowering of the suction pad to be close to the upper surface of the support of the glass plate, the mounting of the glass plate from the suction pad to the support and the suction lifting of the glass plate are reliably performed. .

  In addition, by using a servomotor that is numerically controlled for the lifting / lowering motor that rotationally drives the crankshaft and thus the crank, if the lifting / lowering servomotor and the transport control motor for transport movement are controlled simultaneously, the transport of the glass sheet During the movement, the suction pad is used to raise the height of the glass sheet transfer line so that collision, contact, avoidance, etc. with others can be achieved, and as the processing position for the next glass sheet transfer is approached, the glass sheet is gradually moved When it is lowered and reaches the next processing position of the glass sheet transfer, the suction pad can be accurately positioned at the height position of the minimum distance necessary for the glass sheet transfer.

  At this processing position, the glass plate is lowered to the minimum distance, and the glass plate is opened to the glass plate support and transferred. Next, the suction pad rises again to the height of the required minimum distance in the sky, and at the same time, starts the return stroke in the sky. With the start of the return stroke, the empty suction pad is further raised, lowered as it approaches the original processing position, and returned to above the glass plate support at the original processing position. It is possible to wait until the transfer starts.

  For this reason, the time for receiving and lifting the glass sheet and the time from this lifting to the start of transport to the next processing position, and the time from the drop of the suction pad to the completion of the suction and lifting of the glass sheet are reduced. Furthermore, the time until the start of transport of the received glass sheet is also reduced.

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

  ADVANTAGE OF THE INVENTION According to this invention, the speed of conveyance of a glass plate from a processing position to a processing position is speeded up, the tact of a processing operation is made faster, and the glass plate processing method and glass which can further increase the production of the processed glass plate A plate processing apparatus can be provided.
