Description

  The present invention relates to a transfer device for a plate-like body such as a glass plate.

  For example, as shown in Patent Document 1, in manufacturing a rectangular plate-shaped body, the direction of the plate-shaped body flowing on the conveyance path may be changed by a predetermined angle (90 degrees in Patent Document 1). In Patent Document 1, a rotary transfer device including four suction portions at 90-degree intervals around the rotation axis is provided on the side of the conveyance path. The rotation transfer mounting device sucks the plate-like body on the conveyance path at the suction section, and rotates 90 degrees in that state, thereby converting the orientation of the plate-like body by 90 degrees and solving the suction state at that position. The plate-like body is returned to the conveyance path. The rotary transfer device rotates intermittently 90 degrees in one direction around the rotation axis, and each time it stops, it adsorbs the plate-like body on one of the two adsorbing parts adjacent in the circumferential direction and the plate on the other side. The state body is detached. Thereby, it is possible to sequentially change the direction of the plate-like bodies flowing one after another on the conveyance path by 90 degrees.

  However, in the configuration as described above, it is necessary to secure a space on the side of the conveyance path for rotating the rotary transfer device and moving the suction portion when returning the suction portion from the separation position to the suction position again. is there. Therefore, there is a problem that the space required for the facilities becomes wide.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a plate-shaped body transfer device that can save space.

  A plate-like body transfer device that solves the above problems includes a support shaft provided on a side of a conveyance path that conveys the plate-like body, an adsorption position that adsorbs and holds the plate-like body of the conveyance path, and the plate. An oscillating arm that reciprocally oscillates around the support shaft between the detachment position where the adsorbed state of the object is released and returned to the conveyance path, and the oscillating arm adsorbs and holds the plate-like object In this state, the plate-like body is moved from the suction position to the disengagement position while rotating the plate-like body by a predetermined angle around the support shaft while changing the direction of the plate-like body by the predetermined angle.

  According to this configuration, the swing arm that reciprocally swings by a predetermined angle between the suction position and the separation position on the transport path is provided around the support shaft provided on the side of the transport path. Thereby, since the rocking | fluctuation operation | movement of a rocking | swiveling arm does not require the space of the back surface side (counter conveyance path side) of a spindle, space saving of a transfer apparatus can be achieved.

In the plate-like body transfer device, it is preferable that a plurality of the swing arms are provided while being shifted in the axial direction of the support shaft.
According to this configuration, since the plurality of swing arms are provided so as to be displaced in the axial direction of the support shaft, the swing arms can be configured not to interfere with each other during reciprocal swing.

  In the plate-like body transfer device, at least one of the plurality of swing arms swings toward the suction position, and at least one of the remaining swing arms swings toward the release position. It is preferable that it is comprised.

  According to this configuration, when the swing arm that has detached the plate-like body returns to the suction position, another swing arm holds the plate-like body and is moving toward the release position. The tact time can be shortened compared to the case where only one is used.

In the plate-like body transfer device, it is preferable that the swing shaft of each swing arm is set only on one side of the transport path.
According to this configuration, since each swing arm is provided only on one side of the conveyance path and not provided on the other side, the space of the transfer device can be further reduced.

  In the plate-like body transfer device, a first elevating device provided below the swing arm at the suction position and ascending the plate-like body on the transport path to the swing arm; and It is preferable that the apparatus further includes a second lifting device provided below the swing arm, which lowers the plate-like body detached from the swing arm and returns it to the transport path.

  According to this configuration, since the swing arm sucks and holds the plate-like body raised by the first lifting device at the suction position, it becomes easy to suck the plate-like body to the swing arm. Further, since the swing arm places the plate-like body on the second lifting device in the lifted state at the disengagement position, the distance until the plate-like body is detached from the swing arm and placed thereon can be shortened. As a result, the load applied to the plate-like body can be suppressed.

  According to the plate-like body transfer device of the present invention, space saving can be achieved.

The transfer device 12 is provided. The 1st conveyance conveyor 11a and the 2nd conveyance conveyor 11b are arranged in a straight line and are horizontally arranged, and comprise the linear conveyance path 11. FIG. The transfer device 12 converts the rectangular glass sheet G, which has been conveyed in the right direction (conveying direction) in FIG. 1 by the first conveying conveyor 11a, into the second conveying conveyor 11b side while converting the angle by 90 degrees in the horizontal direction. To be transferred to. The second transport conveyor 11b transports the glass plate G in the same direction as the transport direction of the first transport conveyor 11a.

  In addition, in the pre-process of the transfer of the glass plate G by the transfer device 12, for example, in the process in which the glass plate G is transferred by the first transfer conveyor 11a, both left and right ends (in FIG. 1) with respect to the transfer direction of the glass plate G. End processing (first end processing) of both long sides of the glass plate G is performed. Then, in the step after the glass plate G is converted into an angle of 90 degrees in the horizontal direction by the transfer device 12 and transferred to the second transfer conveyor 11b side, the glass plate G is transferred by the second transfer conveyor 11b. In the process, end processing (second end processing) of both left and right ends (both short sides of the glass plate G in FIG. 1) with respect to the conveying direction of the glass plate G is performed. In other words, the transfer device 12 converts the orientation of the glass plate G by 90 degrees in the horizontal direction so that the end portions of all four sides of the glass plate G can be processed.

  As shown in FIGS. 1 and 2, the transfer device 12 has a support shaft 13 provided at a position that is in the middle of the transport conveyors 11 a and 11 b and a base end portion of the transport path 11. A pair of swing arms 14 and 15 (first swing arm 14 and second swing arm 15) supported by the shaft 13 and motors 16 and 17 for driving the swing arms 14 and 15, respectively, are provided. ing. The central axis of the support shaft 13 is parallel to the vertical direction and is perpendicular to the horizontally arranged conveyors 11a and 11b.

  The first and second swing arms 14 and 15 have the same configuration (the same shape), are arranged side by side in the axial direction of the support shaft 13, and extend from the support shaft 13 to the conveyance path 11 side. Each is configured as follows. Of the swing arms 14 and 15, the one on the upper side in the vertical direction is the first swing arm 14, and the one on the lower side in the vertical direction is the second swing arm 15. Each of the swing arms 14 and 15 is configured such that, based on the operation of the motors 16 and 17, the distal end side reciprocally swings 90 degrees about the base end side on which the support shaft 13 is supported. That is, the swing shafts of the swing arms 14 and 15 are coaxial.

  As shown in FIG. 1, arc-shaped first and second arcs that support the distal ends of the first and second swing arms 14 and 15, respectively, at opposite positions across the conveyance path 11 with respect to the support shaft 13. Rails R1 and R2 are provided vertically along the vertical direction. And the roller 18 which rolls on the 1st and 2nd rail R1, R2 is each provided in the front-end | tip part of the 1st and 2nd rocking | swiveling arms 14 and 15. As a result, the front ends of the swing arms 14 and 15 are supported by the rails R1 and R2 so as not to be cantilevered only on the base end side, but the swing arms 14 and 15 are smoothly supported by the rollers 18. Oscillation is realized.

  The first and second swing arms 14 and 15 each have a suction holding portion 22 including a plurality of suction chucks 21 at an intermediate portion between the tip end portion and the base end portion thereof. Each suction chuck 21 of each suction holding portion 22 is connected to an intake pump (not shown) via a pipe (not shown) routed from the support shaft 13 to each swing arm 14, 15. The glass plate G is adsorbed to the adsorption chuck 21 by the operation of the intake pump. When the operation of the intake pump is stopped, the suction state is released and the glass plate G is detached from each chuck for chucking 21. The adsorption and detachment of each of the chucks 21 can be independently operated on the first swing arm 14 side and the second swing arm 15 side.

  Each of the swing arms 14 and 15 has a support shaft 13 between a suction position where the suction holding part 22 is located on the first transport conveyor 11a and a separation position where the suction holding part 22 is located on the second transport conveyor 11b. Oscillates around the center. FIGS. 1 and 2 show a state in which the first swing arm 14 is in the suction position and the second swing arm 15 is in the release position. The position is set at a position that is 90 degrees apart from the support shaft 13. Further, the suction positions of the first and second swing arms 14 and 15 are the same as viewed from the axial direction of the support shaft 13, and the removal positions of the first and second swing arms 14 and 15 are also the support shaft. 13 in the same position as seen from the axial direction.

  In the present embodiment, the first and second swing arms 14 and 15 swing back and forth in synchronization with the opposite directions. That is, from the state where the first and second swing arms 14 and 15 are at the suction position and the separation position, respectively, the first swing arm 14 is toward the separation position and the second swing arm 15 is toward the suction position. The first and second swing arms 14 and 15 simultaneously arrive at the disengagement position and the suction position, respectively, at the same time. The same applies when the first swing arm 14 rotates from the disengagement position to the suction position and the second swing arm 15 rotates from the suction position to the disengagement position.

  A first elevating device 23 for raising the glass plate G is provided below the suction holding portion 22 of the first and second swing arms 14 and 15 at the suction position. On the other hand, a second elevating device for lowering the glass plate G detached from the swing arms 14 and 15 below the suction holding portion 22 of the first and second swing arms 14 and 15 in the separation position. 24 is provided. In addition, the 1st and 2nd raising / lowering apparatuses 23 and 24 are each comprised so that it may not interfere physically with the 1st and 2nd conveyance conveyor 11a, 11b.

  Moreover, in this embodiment, the glass plate conveying apparatus 10 controls the driving of the motors 16 and 17 that are the driving sources of the conveying conveyors 11a and 11b, the lifting devices 23 and 24, and the swing arms 14 and 15. A control unit (not shown) is provided. A control part controls the drive timing of each conveyance conveyor 11a, 11b, each raising / lowering apparatus 23, 24, and each motor 16,17. Further, the control unit swings the swing arms 14 and 15 based on the transport speed of the transport conveyors 11a and 11b, the lift speed and lift stop position of the lift devices 23 and 24, and the driving of the motors 16 and 17, respectively. It is designed to control the operation.

Next, operation | movement of the glass plate conveying apparatus 10 of this embodiment is demonstrated with the effect | action.
The glass plate Ga transported on the first transport conveyor 11a is transported to a position above the first lifting device 23 after the first end processing (long side end processing) is performed. At this time, the first conveyor 11a is temporarily stopped.

  Thereafter, as shown in FIG. 2, the glass plate Ga is raised by the first lifting device 23, and the surface of the glass plate Ga abuts against each suction chuck 21 of the first swing arm 14 at the suction position ( Alternatively, they are opposed to each other through a slight gap) and are attracted to each chuck 21 by the operation of the intake pump.

  At this time, the second swing arm 15 is at a separation position on the second conveyor 11b. When the suction holding portion 22 of the second swing arm 15 sucks and holds the glass plate Gb (the glass plate having the first end processed) (see FIG. 2), the glass is stopped by stopping the intake pump. The plate Gb is detached from each chuck for chucking 21 and the glass plate Gb is placed on the raised second lifting device 24.

  Thereafter, as shown in FIG. 3, the first and second lifting and lowering devices 23 and 24 are lowered. At this time, the glass plate Gb placed on the second lifting device 24 is transferred onto the second transport conveyor 11b in the transport stopped state as the second lifting device 24 is lowered.

  Next, as shown in FIG. 4, the first swing arm 14 holding the glass plate Ga by suction is rotated in the positive direction from the suction position toward the separation position, and does not hold the glass plate. The second swing arm 15 in the state is rotated in the reverse direction from the disengagement position toward the suction position. Simultaneously with the start of rotation of the swing arms 14 and 15, the operations of the conveyors 11a and 11b are resumed, and the glass plate Gb transferred onto the second conveyor 11b is moved to the rear by the second conveyor 11b. It is conveyed to the process (the second end portion processing). On the other hand, a new glass plate Gc is transported toward the first lifting device 23 on the first transport conveyor 11a.

  After that, as shown in FIG. 5, the first swing arm 14 that sucks and holds the glass plate Ga arrives at the disengagement position above the second transport conveyor 11b, and at the same time, the second swing arm 15 moves to the first transport conveyor. Arrives at the suction position above 11a. Here, the first swing arm 14 is rotated 90 degrees around the support shaft 13 from the disengagement position where the rotation is started to the end suction position, but the glass plate is held by suction on the first swing arm 14. The relative posture of Ga with respect to the first swing arm 14 does not change. Therefore, the glass plate Ga is angle-converted by 90 degrees in the horizontal direction from the direction in which the long side is parallel to the transport direction of the first transport conveyor 11a, and the direction in which the short side is parallel to the transport direction of the second transport conveyor 11b. (See FIG. 1).

  At the same time (or before the second swing arm 15 arrives at the suction position), the glass plate Gc on the first transport conveyor 11a is transported to a position above the first lifting device 23. Then, the glass plate Gc is placed on the second swing arm 15 at the suction position in the same manner as the suction of the glass plate Ga of the first swing arm 14 and the separation of the glass plate Gb of the second swing arm 15 described above. While being held by suction, the glass plate Ga is detached from the first swing arm 14 at the separation position. In addition, each raising / lowering device 23,24 comes to be driven so that a raise stop position may be displaced according to the height position of each adsorption | suction holding part 22 of the 1st and 2nd rocking | swiveling arms 14,15. Yes.

  Thereafter, the second swing arm 15 holding the glass plate Gc by suction is rotated 90 degrees in the forward direction from the suction position to the separation position, the direction of the glass plate Gc is changed by 90 degrees, and the glass plate is The first swing arm 14 that is not held is rotated 90 degrees in the reverse direction from the disengagement position to the suction position. Further, the glass plate Ga detached from the first swing arm 14 is transferred from the second lifting / lowering device 24 onto the second transport conveyor 11b in the same manner as described above, and is then processed by the second transport conveyor 11b ( The second end processing).

  By repeating the operations of the conveyors 11a and 11b, the lifting devices 23 and 24, and the swing arms 14 and 15 as described above (the swing arms 14 and 15 swing 90 degrees back and forth), the first transport is performed. The glass plates G conveyed one after another from the conveyor 11a are transferred to the second conveyor 11b while being sequentially converted by 90 degrees by the swing arms 14 and 15, respectively.

Next, characteristic effects of the present embodiment will be described.
(1) The transfer device 12 included in the glass plate conveyance device 10 is a reciprocating rocker in a range of 90 degrees above the conveyance path 11 around the support shaft 13 provided on the side of the conveyance path 11. Each oscillating arm 14 and 15 is provided. Each swing arm 14 and 15 sucks and holds the glass plate G from the transport path 11 (first transport conveyor 11a), rotates 90 degrees in that state, and changes the direction of the glass sheet G by 90 degrees. 11 (second transport conveyor 11b), and then rotated 90 degrees in the reverse direction to return to the suction position on the first transport conveyor 11a side. According to this configuration, the swinging operation of the swing arms 14 and 15 does not require a space on the back side (the non-conveyance path side) of the support shaft 13, so that the space for the transfer device 12 can be saved. .

(2) Since the swing arms 14 and 15 are arranged side by side in the axial direction of the support shaft 13, the swing arms 14 and 15 can be configured not to interfere with each other during reciprocal swing.
(3) It is configured such that one of the first and second swing arms 14 and 15 swings toward the suction position and the other swings toward the separation position. That is, for example, when the first swing arm 14 that has detached the glass plate G is returning to the suction position, the second swing arm 15 is holding the glass plate G and is moving toward the release position. The tact time can be shortened compared to the case where only one is used. Furthermore, in this embodiment, since each swing arm 14 and 15 is synchronously driven in the opposite direction (the timing of rotation start and stop coincides), it can further contribute to shortening the tact time.

  (4) The swing shafts (support shafts 13) of the swing arms 14 and 15 are set only on one side of the transport path 11. That is, since each swing arm 14 and 15 is provided only on one side of the transport path 11 and not provided on the other side, the space of the transfer device 12 can be further reduced.

  (5) The transfer device 12 is a first lifting device that is provided below the suction position and raises the glass plate G on the transport path 11 (first transport conveyor 11a) to the swing arms 14 and 15 at the suction position. 23 and a second lifting device 24 that is provided below the separation position and lowers the glass plate G detached from the swing arms 14 and 15 and returns it to the conveyance path 11 (second conveyance conveyor 11b). According to this configuration, each swing arm 14, 15 sucks and holds the glass plate G raised by the first elevating device 23 at the suction position, so that the glass plate G is sucked to each swing arm 14, 15. It becomes easy. Further, since each of the swing arms 14 and 15 places the glass plate G on the second elevating device 24 in the lifted state at the disengagement position, the glass plate G is detached from the respective swing arms 14 and 15 and placed. As a result, the load applied to the glass plate G at the time of separation can be suppressed.

  (6) The transfer device 12 is provided with rails R1 and R2 that support the distal ends of the swing arms 14 and 15, and the swing arms 14 and 15 roll on the rails R1 and R2. A roller 18 is provided. As a result, the swinging arms 14 and 15 can be smoothly swung by the roller 18 while the swinging arms 14 and 15 are stably supported.

In addition, you may change the said embodiment as follows.
The drive timings of the conveyors 11a and 11b, the lifting devices 23 and 24, and the swing arms 14 and 15 (motors 16 and 17) are not limited to the above-described embodiments, and are appropriately changed according to the configuration. May be.

  In the above embodiment, the conversion angle of the glass plate G by the swing arms 14 and 15 is 90 degrees (that is, the swing angle range of the swing arms 14 and 15 is 90 degrees). However, the present invention can be applied to the case where the conversion angle of the glass plate G is less than 90 degrees or larger than 90 degrees. For example, when the first transport conveyor 11a and the second transport conveyor 11b are not straight but at an angle in plan view due to space restrictions in the manufacturing factory, the swing arms 14 and 15 swing. The angle range is preferably less than 90 degrees (or greater than 90 degrees).

  In the above-described embodiment, the transport path 11 returns the first transport conveyor 11 a on which the glass plates G are attracted by the swing arms 14 and 15 and the glass plates G held by the swing arms 14 and 15. Although it is configured separately from the second conveyor 11b, for example, a configuration in which the conveyors 11a and 11b are continuous (that is, a single conveyor configuration) may be used.

  In place of the lifting devices 23 and 24 of the above embodiment, for example, the suction chucks 21 of the swing arms 14 and 15 may be configured to be liftable. In such a configuration, the configuration of the swing arms 14 and 15 is complicated. However, if the lifting devices 23 and 24 are provided on the side of the conveyors 11a and 11b as in the present embodiment, The moving arms 14 and 15 can be simplified.

  In the above embodiment, the swing axes of the swing arms 14 and 15 are coaxial. However, the present invention is not limited to this, and the support shafts 13 corresponding to the swing arms 14 and 15 are provided. You may comprise so that each rocking | swiveling arm 14 and 15 may rock | fluctuate with an individual rocking | fluctuation shaft. This configuration also provides substantially the same effect as the above embodiment. Further, when the support shafts 13 of the swing arms 14 and 15 are individually provided, the support shafts 13 may be provided only on one side of the transport path 11, and the support shafts 13 may be provided on the transport path 11. It may be provided on both sides.

  In the above embodiment, the transfer device 12 includes the two swing arms 14 and 15, but the swing arm may have one configuration or three or more configurations. When the number of swing arms is three or more, the tact time can be further improved.

  In the above embodiment, in the process before and after the transfer of the glass plate G by the transfer device 12, end processing (first and second end processing) on both the left and right sides with respect to the conveyance direction of the glass plate G is performed. However, other than this, for example, the shape inspection of the ends of the left and right ends with respect to the conveying direction of the glass plate G may be performed.
