The present invention relates to a tile rotation transfer device that is effective when applied to the case of changing the direction of tiles sequentially stacked on a tile stacking conveyor.

(Prior Art) In the conventional device of this type,
As shown in the figure, it is known that the intervals between the transfer conveyors 2aE that transfer the tiles 10E in a column shape are widened so that the tiles in the adjacent rows do not interfere with each other during rotation,
In such a case, there is a problem that the lateral width of the transfer conveyor group becomes wide and the installation area becomes large. It is also known to rotate the adjacent tiles 10E sequentially with a time difference in order to reduce the interval between the transfer conveyors 2aE in FIG. 12, but the cycle time for rotating all the adjacent tiles. However, there has been a problem that the processing capacity per unit time is low due to the increase in processing time. Further, as shown in FIGS. 13 and 14, a plurality of rotating mechanisms 7F such as swing motors are provided on a laterally movable holder 40F, and a suction shaft is provided on the rotating shaft 7bF of every other one of the rotating mechanisms.

By raising 60, each cradle 62 pushes up the tiles 10 on each transfer conveyor 2a every other row with a height difference. In the above case, each pedestal 54 of the first push-up table 52 and the second push-up table
Since the height of the pedestal 62 adjacent to the front, back, left and right differs from the pedestal 62 of the 60 by an amount larger than the tile thickness, and the height of the diagonal one is the same, it is pushed up by the pedestals 54, 62. The tiles 10 in the two rows before and after are vertically and horizontally adjacent to each other, but the heights of the tiles 10 differ from each other by an amount larger than the thickness of the tile 10.

Next, the elevating cylinder 33 of the elevating device 21 is activated to operate the elevating plate 3
4, the elevating guide rod 28 and the holder 18 are lowered, and the air suction device 41 of the suction device 5 operates to generate suction force on the suction surface 38a of the suction pad 38. By the lowering of the holding body 18, the suction surface 38a of each suction pad 38 is respectively received by the receiving table 54,
The upper surface of each tile 10 is adsorbed by contacting the upper surface of the corresponding tile 10 on 62. In the above case, the suction surface of each suction pad 38
Since 38a has height differences so that the dimensions up to the upper surfaces of the corresponding pedestals 54 and 62 are the same, the respective suction pads 38a
The adsorption surface 38a of the element securely adsorbs each tile 10. Thereafter, the lifting cylinder 33 is actuated again to raise the holder 18 to its original position, and as a result, each suction pad 38 is also raised while sucking the tile 10 as shown in FIG. Further, the push-up cylinders 58, 58 are operated to operate the first push-up table 52 and the second push-up table 52.
The push-up table 60 is lowered to the original position shown in FIG. 5 so that the next tile 10 can be received.

Next, the traverse cylinder 31 of the traverse device 20 is operated to move the traverse body 27 to the right in FIG. 2, and the tile 10 in the adsorbed state is moved above the release position B of the tile transfer device 2. Further, while the traverse cylinder 31 is operating, the swinging motors 45 are operated to rotate the center gears 46 in the directions of the arrows, and the center gears 46 cause the adsorbents 40 to move 90 degrees in a horizontal plane.
Rotate 180 degrees or 180 degrees. As a result, the tile 10 adsorbed on the adsorption pad 38 is rotated 90 degrees or 180 degrees. When rotating the tiles 10 as described above, each tile 10 is
Since the heights of the adjacent ones on the left and right are different from each other by more than the thickness of the tile, it is possible to prevent the tiles 10 from interfering with each other even when the front, rear, left and right spaces of the tile 10 are made small enough to substantially contact each other. It should be noted that the first receiving / exiting table of the tile receiving / exiting device 9
As shown in FIG. 9, the 65 and the second receiving and descending table 66 are preliminarily raised, and the upper surfaces of the receiving stands 67, 68 are located above the upper surface of the transfer conveyor 2a.

Next, the lifting cylinder 33 is actuated again to lower the holding body 18, and the suction pad 38 lowers the tile 10 in the suction state onto the pedestals 67 and 68 of the first receiving and descending table 65 and the second receiving and descending table 66, In this state, the switching valve of the air suction device 41 operates to stop the suction action of the adsorbent 40. As a result, the tiles 10 adsorbed on the adsorption surfaces 38a are released on the corresponding pedestals 67 and 68. After that, the lifting cylinder 33 operates again to raise the holding body 18 and the respective adsorbing bodies 40, and then the lateral movement cylinder 31.
Is activated again to move the lateral moving body 27 to the original suction position A shown in FIG.
Move above. It should be noted that the swing motor 45 may be reversely rotated while the laterally moving body 27 is moved back as described above, or may be reversely rotated in the next cycle. After that, the first receiving and descending table 65 descends and each receiving table 67
The upper tile 10 is transferred onto each transfer conveyor 2a, and each tile 10 in the first row is transferred to the next process by the transfer conveyor 2a. After that, the second receiving and descending table 66 descends to transfer the tiles 10 on each pedestal 68 onto the transfer conveyor 2a, and transfers each tile 10 in the second row to the next process by the transfer conveyor 2a. The first and second surrender / receiving tables 65 and 66 are placed on the tile 1
After passing 0, it rises again and prepares for the next cycle. While the adsorbent 40 transfers the tile 10 to the releasing position B, the next tile 10 comes into contact with the fixed stopper 50 at the adsorbing position A, and the above operation is repeated.

In the present application, every other one of the adsorbents is arranged on the holder so as to be able to move up and down as described in JP-A-53-131668, and normally the maximum weight is adjusted by its own weight or spring. Every other suction surface located at the lower end is lower than other suction surfaces,
When the holding body is moved down, when each adsorbent comes into contact with the tile upper surface, every other adsorbent is pushed up by the tile so that each adsorbing surface follows the height of the tile upper surface. Further, the holding body may be moved back and forth and up and down by a crane or the like. Further, the adsorbent rotating device may be configured such that a timing belt is suspended around a timing pulley provided on each adsorbent, and the timing belt is rotated by a small motor. Furthermore, the number of adsorbents in the front-rear direction and the left-right direction may be arbitrarily changed.

(Effects of the Invention) As described above, according to the present invention, when tiles 10 are transferred in a row by the tile transfer device 2, the upper surfaces of a plurality of tiles vertically and horizontally adjacent to each other at the midway position of each transfer locus 11 are arranged. After being sucked up by the suction surface 38a of the suction body 40 and then lifted, the surface is rotated 90 degrees or 180 degrees, and then each tile 1
It is possible to return 0 to the original transfer path 11, and as a result, even if the tile 10 is rotated during transfer, quality control of tiles can be easily performed for each transfer path.

Further, as described above, when a plurality of tiles 10 vertically and horizontally adjacent to each other in each transfer trajectory 11 are rotated 90 degrees or 180 degrees, each adsorbent 4
0 can be simultaneously rotated by the adsorbent rotating device 7 to rotate each tile 10 simultaneously by 90 degrees or 180 degrees. As a result, the cycle time for tile rotation can be shortened and the processing capacity per unit time can be increased. it can.

In addition, the tile 10 rotated as described above is transferred to the original transfer path 11
When returning to the inside, the tile can be returned to the inside of the transfer path 11 at a position behind the position where the tile 10 is lifted from within the transfer path 11, and as a result, when the tile 10 is returned to the transfer path 11, the tile is rotated next. It should be possible to transfer the proper tiles to the upper position and increase the processing capacity.

Further, when a plurality of vertically and horizontally adjacent tiles 10 are simultaneously rotated 90 degrees or 180 degrees as described above, the heights of vertically and horizontally adjacent tiles 10 are different from each other by an amount larger than the thickness of the tiles 10. Even if the mutual space between the adjacent tiles 10 is extremely small, mutual interference between the tiles 10 can be prevented, and as a result, the vertical and horizontal spaces between the tiles 10 to be transferred can be reduced, and the width of the tile transfer device 2 can be reduced to reduce the installation space. There is an effect that can be done.
