[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of transferring an unfired tile to a firing jig or the like from a tile conveyor or firing a fired tile from a firing jig or the like in preparation for firing. The present invention relates to a method and an apparatus for transferring tiles to be transferred to a conveyor.

2. Description of the Related Art In the art, firing is performed with a tiled body in an inclined state for the purpose of effectively utilizing the heat of a firing furnace and improving the quality of tiles. For this reason, unfired tiles supported in an inclined position are carried into a firing furnace, and fired tiles supported in an inclined position are extracted from a firing jig or the like for inspection and inspection and packing. Is carried out to such a process. Therefore,
In order to support the orientation of the tile in a tilted state, the firing jig used is one in which a large number of supports are provided on the cradle of the firing jig at inclined intervals to support the back surface of the tile. It had been. Further, a so-called needle mountain conveyor provided with a large number of pairs of inclined support members on the outer periphery of a conveyor belt has been adopted as a tiled material conveyor for transporting unfired tiled materials (Japanese Patent Laid-Open No. 9-277239). JP-A-8-187715). For example, when transferring an unfired tile substrate supported in an inclined state to a support of a tile substrate conveyor to a firing jig, a plurality of tile substrates are collectively gripped by a so-called gripper, and the tile substrate is removed. The tiles are taken out by pulling them out from between the supports while being along the inclination direction of the support of the tiled conveyor, and the tiles taken out are reinserted while being placed along the inclination direction of the support of the firing jig. Transferring the substrate was done.

However, when transferring tiles to a firing jig, the tiles must be inserted between relatively narrow supports while being arranged along the direction of inclination of the supports provided in an inclined state. However, there was a risk that the presence of the support during the insertion would be an obstacle. Further, even when the fired product (fired tile base) is transferred from the firing jig to the fired product conveyor having the inclined support, the presence of the support of the conveyor may be an obstacle. Therefore, in the related art, the tile is inserted between the supports in an inclined state, so that the support does not become an obstacle,
Accuracy of the work of inserting tiles was required. As a result, in order to ensure the accuracy of the above-described work, in addition to complicating the structure such as a gripping mechanism that constitutes the means for transferring tiled fabric, the control tends to be complicated control such as numerical control. The complexity of the structure, operation and control of the substrate transfer equipment was unavoidable. In addition, it is possible to suppress an obstacle at the time of insertion by providing a margin between the supports into which the tiles are inserted and a sufficient interval as compared with the thickness of the tiles. However, it goes without saying that the number of tiles that can be mounted on the firing jig decreases by increasing the interval.
There is a problem that the efficiency of heat utilization of the firing furnace is lacking.

[0004]

The problem to be solved by the present invention is that the conventional method and apparatus for transferring tile tiles transfer tile tiles which are liable to be deformed such as warpage due to drying to a firing jig. At the time of loading, the tiles were transferred without checking the orientation of the tiles inserted between the supports with respect to the spacing of the supports of the firing jig. The tiles often collided with the upper end of the support due to interference. Even if one tile material collides with the support, a series of production facilities must be stopped, and as a result, the productivity of the tile material is greatly impaired.

[0005] It is an object of the present invention to transfer a tile from a first tile arrangement means to a second tile arrangement means such as a firing jig provided with a plurality of supports in an inclined state.

First, the unfired tile substrate W is sequentially sent to the tile substrate conveyor 18 by the belt conveyor 20. The tile substrate W sent to the tile substrate conveyor 18 is transferred to the support 4 of the tile substrate conveyor 18.
4, the posture is controlled from the horizontal state to the standing state (see FIGS. 1 and 4). The tiles W supported by the support 44 are lined up on the tile conveyor 18 while maintaining the upright state.

Next, when nine tiles W are arranged in a row on the tile conveyer 16, for example, the tile conveyer 1 is set in advance.
The transfer means 22 waiting above the 6 lowers the lifting frame 64 via the crank mechanism 86 by the operation of the drive motor 84. At this time, the lifting frame 64
Is held in a horizontal state, and each gripper 72 of the displacement frame 66 is in a vertical state. The holding plates 96, 96 of the gripper 72 are previously opened, and the gripper 72 is When descending to the position where W is gripped, the descending of the elevating frame 74 is stopped. Next, the drive source (not shown) of each gripping tool 72 is operated, and the link mechanism 98 is operated.
To hold the tiles W by closing the holding plates 96, 96 through
Sandwich. At this time, the holding plates 96 of the nine sets of gripping tools 72
, The nine tiles W are sandwiched collectively,
The tile substrate W is gripped by the gripping tool 72 without being damaged or falling off by the cushioning material provided inside the holding plate 96.

When the gripper 72 grips the tile substrate W, the drive motor 84 for raising and lowering operates to raise the lifting frame 64, but stops when the lifting frame 64 moves up and down to the original position (see FIG. 7). Next, the movable carriage 62 travels on the gate-shaped frame 80 in response to the operation of the drive motor 82 for traveling, and the tile substrate W gripped by the gripping tool 72 moves upward of the firing jig conveyor 18. When the tile body W reaches above the firing jig conveyor 18, the movable carriage 62
Is stopped (see FIG. 8).

The firing jig 120 placed on the traveling carriage 50 is on standby on the firing conveyor 18, and at this time, the traveling carriage 50 is fixed by the stopper 54. Next, the firing jig 120 placed on the traveling carriage 50
In order to make the support 124 of the firing jig 120 correspond to the descending tile W, the support 124 of the firing jig 120 is used.
The jig displacement mechanism 52 so that
To incline upward. Specifically, the machine base 46
Is operated by the operation of the air cylinder 56 provided at the end of the rod 58, and the receiving piece 60 provided at the end of the rod 58 raises the other side of the back surface of the firing jig 120 (see FIG. 9).

At this time, the air cylinder 92 for tilting the displacement frame 66 is operated, and the displacement frame 66 is tilted with one side thereof facing downward. And the displacement frame 6
6 is tilted, but the regulating piece 102 of the holding plate 96 is slightly restricted by the regulating roller 112 of the connecting piece 110. Therefore, when the displacement frame 66 is inclined, the holding plate 96 is slightly regulated by the regulating roller 112,
The gripping tool 72 is directed substantially vertically so that the tile body W maintains a substantially vertical state (see FIG. 9). At this time, the tile substrate W gripped by the gripping tool 72 is maintained in a substantially vertical state, and is located on an extension between the supports 124 of the firing jig 120 located below. In addition, the height of the lower end (tail S) of the tile substrate W gripped by each gripping tool 120 is such that the tilting of the displacement frame 66 causes the gripping tool 7 on one side to be inclined.
The height increases stepwise from 2 toward the gripping tool 72 on the other side. The height of these tiles W corresponds to the pedestal 122 of the inclined firing jig 120, and the attitude of the tiles W corresponds to the attitude of the support 124 (see FIG. 9). reference). As described above, the gripper displacement mechanism 70 and the gripper tilting mechanism 74 realize the displacement of the height of the tile substrate W and the displacement of keeping the tile substrate W substantially vertical. P0 to P1 in FIG. 16 indicate the trajectory of the lower end of the tile W at this time.

Next, the elevating frame 64 of the transfer means 22 is lowered by the operation of the elevating drive motor 84, and the held tile W is lowered toward the firing jig 120. The lower end of the descending tile body W is the support 124 of the firing jig 120.
, The descent of the tile body W stops (see trajectories P1 and P2 in FIGS. 10 and 16). The position of the lower end of the tile body W will be described in detail. The lower end position of the tile body W that has been lowered and stopped faces the support surface 136 of the support 124 on the back side with respect to the lower end of the tile body W.
Is positioned so as not to interfere with the tile W (see FIG. 10). And the holding plate 96 is a connecting piece 1
It is in a state where it is slightly subject to 10 regulations.

Next, the air cylinder 104 provided on the displacement frame 66 is operated, the rod 106 end of the air cylinder 104 is retracted, and the tilting rod 108, the connecting piece 110, the regulating roller 112, and the regulating piece 102 of the holding plate 96 are moved. , The holding plate 96 is inclined toward one side (trajectories P2 to -P3 in FIG. 16, see FIG. 17). Therefore, the lower end of the tile body W is inclined toward one side (the support member 124 on the front surface side), but the support member 124 on the front surface is not at a position where it interferes with the tile body W (see FIG. 11). Next, the air cylinder 104 of the displacement frame 66 is operated again, and the rod 106 of the air cylinder is advanced. As the rod 106 advances, the gripper 72 receives the release of the regulation by the regulating roller 112, and is tilted toward the other side so that the gripper 72 is completely vertical. It is brought into contact with the support surface 136 of the support 124 on the back side (FIG. 12).
See). At this time, even if the gripped tile substrate W has a slight warp or the support 124 has a slight variation in the vertical state, the gripper 72 can be controlled by the regulating roller 11.
2, the contact between the tile substrate W and the support surface 136 of the support member 124 depends on the state of each of the tile substrate W and the support member 124. The lower end of the tile body W is supported by the support surface 136 of the support 124 on the back side of the tile body W.
When the contact is made, the pressing arm 118 of the fixing mechanism 76 that has been opened presses the gripping tool 72 from both sides to fix all the holding plates 96. Pressing arm 118 of fixing mechanism 76
Presses the gripping tool 72, the gripping tool 72 holding the tile substrate W is positioned, and does not move. And
When the tile substrate W is fixed by the fixing mechanism 76, the moving air cylinder 69 provided on the elevating frame 64 is operated to slightly move the entire elevating frame 66 to one side with respect to the fixed frame 68. Air cylinder for moving 6
9, the gripper 72 is slightly moved toward one side with the movement of the lifting frame 66.
6, the lower end of the tile body W is supported on the back side 12 of the tile body W while the posture of each tile body W is maintained by the pressing arm 118 of FIG.
Slightly away from 4. Therefore, at this point, the gripper 7
The tile substrate W gripped by 2 is the support 1 of the firing jig 120.
It is in a state that it is surely inserted between the two.

Next, the firing jig 120 on the traveling carriage 50
The lifting frame 64 is lowered so that the tiles W are inserted between the support members 124 (see FIG. 13). Even if the tiles W and the support 124 of the firing jig 120 are warped or the like, the tiles W inserted between the supports 124 are in contact with the support 124, It is inserted toward the cradle 122. Then, when the lower end of the tile body W approaches the pedestal 122, the air cylinder 69 is operated and the pressing of the gripper 72 by the pressing arm 118 is released. Actuation of air cylinder 69 and pressing arm 1
The release of the gripping tool 72 by 18 causes the gripping tool 72 to be in a state where it is not restricted, and goes completely vertically, and the back surface of the tile W and the support surface 136 of the support 124 abut. Then, after slightly lowering the elevating frame 64, the holding plate 96 of the gripper 72 is opened, and the gripping of the tile substrate W by the gripper 72 is released. By opening the gripping tool 72, the tile substrate W is placed on the receiving table 122 of the firing jig 120,
The back surface of the tile body W is received by the support 124 of the firing jig 120. Next, in the firing jig conveyor 18, the air cylinder 56 of the jig displacement mechanism 64 is operated, and the firing jig 120 lifted by the receiving piece 60 with the lowering of the rod 58 is released from the inclined state. The receiving base 122 of the jig 120 is in a horizontal state on the traveling vehicle 50, and the tile substrate W is received in an inclined state with respect to the inclined support 124. On the other hand, the gripping tool 72 that has released the gripping of the tile body W moves up and down, and
6 returns to the horizontal state, and the moving air cylinder 69
Operation returns the lifting frame to the original position. Then, the movable trolley 62 travels on the gate-shaped frame 80, and the gripper 72 of the transfer means 22 moves above the tile substrate conveyor 16 to prepare for the next transfer of the tile substrate W. The firing jig 120 on which the tile ground W is placed travels on the firing jig conveyor 18 together with the traveling carriage 50 upon receiving the release of the stopper 54, and is loaded onto the firing carriage 12 by the jig loading means 24. .

In the case where the fired product conveyor 28 is provided with a support which is continuously connected in an inclined state as in a conventional apparatus, the fired product W on the firing jig 120 is transferred from the firing jig conveyor 18. When transferring to the baked goods conveyor 28, the baked goods conveyor 28 of the tile substrate W gripped by the transfer means 32
Loading and unloading to and from are performed basically in the same manner as the transfer means 22 described above. In this embodiment, in order to move the tile substrate W from the support surface 136 of the support member 124 to one side, the vertical frame 66 is made movable relative to the fixed base 68 as a tile substrate horizontal movement mechanism, and the air cylinder for movement is used. 69
However, since it is only necessary to be able to move the tile ground W gripped by the gripping tool 72 to one side, it can be realized by means such as moving the movable carriage 62 to the negative side.

In the transfer device 10 according to this embodiment,
The posture of the tile body W is displaced in accordance with the support member 124 in the vertical state, and the lower end of the tile body W is tilted toward one side and then returned toward the other side, whereby the support member 124 is returned.
After the orientation of the tile W is confirmed, the insertion of the tile W between the supports 124 is performed after the orientation of the tile W is confirmed, so that firing is performed without colliding the tile W with the support 124. It can be reliably transferred to the second tile base arrangement means such as the tool jig 120. In particular, even when the distance between the supports 124 is small, the tile material W
Can be reliably inserted between the supports 124 without interrupting a series of facilities.
And, for example, nine tiles W were mounted on the firing jig 120 in which only eight tiles W could be mounted in the past, but complicated control such as numerical control was not required.
The structure, operation, and control of the tile transfer device 10 can be simplified. When returning the lower end of the tile body W toward one side toward the other side, the gripper tilt mechanism 7
4 without being restricted by the restriction piece 102.
In addition, the lower end of the tile body W is brought into contact with the support 124 by the weight of the sandwiched tile body W, so that no excessive force acts on the support 124 and the support 1
24 can be prevented from being damaged.
