[Technical field to which the invention belongs]
TECHNICAL FIELD The present invention relates to a method and an apparatus for removing ceramic residue such as glaze and base material that remain after being sintered in a firing jig for a tile base when the tile base is fired by a firing jig.
[0002]
[Prior art]
It is generally known that clay roof tiles can be obtained by molding raw materials mainly composed of clay, glazing the molded tile base as necessary, and firing the glazed tile base. is there.
It is also known that the tile base is placed on a firing jig called a mortar or setter, and the tile base is fired together with the firing jig.
An F-shaped clay roof tile base W (hereinafter, simply referred to as “tile base W” unless otherwise specified) uses, for example, a firing jig 200 made of a refractory material as shown in FIG. It was fired.
The firing jig 200 includes a receiving base 202 that receives the bottom S of the tile base W and a support 204 that supports the back surface N of the tile base W.
The cradle 202 is formed with, for example, eight insertion grooves 206 in preparation for supporting eight tile bases W in an inclined state.
On the other hand, the eight support members 204 respectively corresponding to the eight insertion grooves 206 have a flat plate shape, and an insertion portion 208 to be inserted into the insertion groove 206 of the receiving base 202 is formed at the lower end. It was what was done.
[0003]
Therefore, a method of using the firing jig 200 described above will be described. First, the back surfaces of the eight support bodies 204 are directed to the rear side (left side in the drawing) of the firing jig 200 and provided on each support body 204. By inserting the inserted insertion portion 208 into the insertion groove 206 and holding the support 204 in a state inclined to the back side of the cradle 202, the firing jig 200 can be received by the tile base W. Prepare.
Next, the bottom S of the tile base W is directed toward the cradle 202, and the back surface N thereof is directed toward the front surface (right side in the drawing) of the inclined support 204. By holding the above-described cradle 202, each of the eight tile bases was placed on the cradle 82 in an inclined state, and firing was performed.
[0004]
  However, in the case of firing the glazed tile base W, the glaze melts at the time of firing and flows down or scatters along the surface P of the tilted tile base, and a part of the glaze is fired as a jig for firing. It was apt to adhere to the insertion part 208 of the support body 204 of 200, or to accumulate in the insertion groove | channel 206 of the receiving stand 202 (refer FIG. 10).
  On the other hand, regardless of whether the tile base W is glazed or not, when the tile base W is loaded onto the firing jig 200 in preparation for firing, the back surface N of the tile base W is the support.204At this time, since the tile base before firing is in a relatively brittle state, a part of the tile base W is slightly shaved, and the shavings in which a part of the tile base W is shaved. In other words, the base material was generated, and the base material was apt to be deposited in the insertion groove 206 of the cradle 202.
  In addition, when the firing jig 200 on which the tile base W is placed is transported, the tile base W and the firing jig 200 are rubbed due to vibration during transport, and the generated base material is subjected to the base 202. It was apt to be deposited in the insertion groove 206.
  As a result, it was not possible to avoid solidification of the deposited glaze and base material (hereinafter simply referred to as “ceramic residue GH” without notice) with cooling after firing.
  Therefore, by repeatedly using the firing jig 200, the ceramic residue GH gradually accumulates in the vicinity of the insertion groove 206 of the cradle 202, and the deposited ceramic residue The GH repeatedly melts and solidifies, and the ceramic residue GH fills the insertion groove 206 and eventually gets over the insertion groove 206.
  When the ceramic residue GH in the vicinity of the insertion groove 206 is in such a state, the ceramic residue GH and the tile base W deposited in the vicinity of the insertion groove 206 of the firing jig 200 when the roof tile W is fired. The bottom S side is often baked on each other, and the tile base W is forcibly loaded and unloaded from the firing jig 200 in preparation for the subsequent process while being baked. In particular, scratches were generated on the side, which could cause defective products.
  Also, the firing jig such that the support 204 and the cradle 202 of the firing jig 200 are deformed, deteriorated, or damaged due to repeated melting and solidification of the ceramic residue GH deposited.200The wear of was promoted.
[0005]
[Problems to be solved by the invention]
The problem to be solved by the present invention is that the firing jig is repeatedly used, so that the ceramic residue is gradually deposited near the insertion groove of the cradle. The ceramic residue will melt and solidify repeatedly, and the ceramic residue will fill the insertion groove and eventually get over the insertion groove, and the ceramic residue in the vicinity of the insertion groove When the tile substrate is fired, the ceramic residue and the bottom side of the tile substrate deposited in the vicinity of the insertion groove of the firing jig are often baked together, and the tile substrate remains in the burned state as described above. Since it is forcibly loaded and unloaded from the firing jig in preparation for this step, scratches are generated particularly on the bottom side of the tile base, resulting in defective products.
In addition, wear and tear of the firing jig is promoted such that the support and cradle of the firing jig are deformed, deteriorated, or damaged due to repeated melting and solidification of the deposited ceramic residue.
[0006]
The object of the present invention is to prevent the firing material residue and the tile base material from being seized in the vicinity of the insertion groove of the firing jig cradle by repeatedly using the firing jig. It is to prevent the occurrence of defective products of tile products.
Furthermore, another object is to prevent deformation, deterioration or damage of the support and the cradle due to accumulated ceramics residue, and to improve the service life of the firing jig.

  Removal equipment12The support displacement means will be described.
  The support displacing means is a means intended to peel ceramic residue GH that tends to solidify into the insertion portion 86 of the support 84 of the firing jig 80 and the insertion groove 88 of the cradle 82.
  The support body 84 of the firing jig 80 is pressed from the back surface and displaced from the inclined state toward the standing state.
  The specific structure of the support displacing means will be described. A portal frame 38 is provided so as to straddle the firing jig conveyor 18, and four vertical guides 40 are suspended from the portal frame 38.
  The vertical guide 40 is provided with a plate-like lifting body 42 guided by the vertical guide 40 so as to be lifted and lowered.
  A drive motor 44 is provided on the upper part of the gate-shaped frame 38. The elevating body 42 is connected to the drive motor 44 via a crank mechanism 46, and the elevating body 42 is moved up and down by operating the drive motor 44. Yes.

  A slide air cylinder 52 is provided on the elevating body 42 for the purpose of sliding the slide body 50.
  By operating the slide air cylinder 52, the slide body 50 slides in the horizontal direction.
  On the lower surface of the slide body 50, pressing rollers 54 corresponding to the number of the support bodies 84 inserted into the firing jig 80 are provided via roller support pins 55.
  Since the support displacement means described above is provided above the firing jig conveyor 18, the elevating body 42 moves up and down with respect to the upper transport section 34 of the firing jig conveyor 18, and the upper transport section 34. Above, the slide body 50 moves in the horizontal direction so as to coincide with the conveying direction of the firing jig conveyor 18.
  In this embodiment, in order to smoothly displace the support body 84, as a preferred example, the vicinity of the upper end of the support body 84 is pressed by the pressing roller 54 as the slide body 50 slides. It is not limited to.
  For example, instead of the pressing roller 54, the support body 84 may be contacted simply as a bar or plate.
[0028]
  Next, the removal device12The stationary means for the cradle will be described.
  The cradle stationary means prevents the cradle 82 of the firing jig 80 from following the displacement of the support body 84 when the support body 84 of the firing jig 80 is displaced by the support body displacement means. It is means aiming at.
  Specifically, the firing jig 80 is stationary by pressing the corners of the cradle 82.
  The specific configuration of the cradle stationary means will be described. On both sides of the upper conveyor 34 of the firing jig conveyor 18, advance / retreat guides 56, 56 are provided in a direction perpendicular to the conveyance direction. A pair of advancing / retracting members 58, 58 guided along the guides 56, 56 are provided so as to freely advance and retract (see FIGS. 2 to 4).
  Support members 60, 60 are attached to both ends of the advance / retreat members 58, 58, and a rotation shaft 62 is suspended from the support member 60.
  An approximately L-shaped rotation plate 64 is attached to the rotation shaft 62 so as to be rotatable with respect to the rotation shaft 62 as viewed from above.
  The vicinity of the center of the rotating plate 64 bent in a substantially L shape is supported by the rotating shaft 62, and the rotating plate 64 can rotate with respect to the advance / retreat member 58.
  At both ends of the rotating plate 64, stationary rollers 66 are provided (see FIG. 4).
  Accordingly, the rotating plate 64 is provided with two stationary rollers 66, two rotating plates 64 are provided on one side of the firing jig conveyor 18, and are similarly provided on the other side. Thus, when the stand 82 of the firing jig 80 is stopped by these stationary rollers 66, it comes into contact with the corner of the stand 82 and is fired at the upper conveyance section 34 of the firing jig conveyor 18. 80 can be made stationary.
  In addition, a coil spring 65 is provided so as to connect the rotating plate 64 and the support member 60 so that the rotating plate 64 can be returned to the original position when the rest of the cradle 82 is released. (See FIG. 4).
  In this embodiment, the movement of the stationary roller 66 is realized by the operation of the stationary air cylinder 68 provided on one side of the firing jig conveyor 18.
[0029]
Next, an air spray mechanism will be described as a specific example of the ceramic residue removing means.
The air blowing mechanism blows off the ceramic residue GH that tends to stay in the insertion groove 88 of the receiving table 82 after the ceramic residue GH is peeled off by the support displacing means.
The specific structure of the air blowing mechanism will be described. The air ejection nozzle 70 is attached to the advance / retreat member 58 on one side of the cradle stationary means, and advances toward the firing jig 80 as the advance / retreat member 58 advances. (Refer to FIG. 3 and FIG. 4, the air blowing mechanism is not shown for convenience in FIG. 2).
The ejection end 72 of the air ejection nozzle 70 is directed to the vicinity of the insertion groove 88 of the cradle 82 of the firing jig 80, and the ceramic industry tends to stay near the insertion groove 88 of the cradle 82 of the firing jig 80. The residue GH is blown off.
The air ejection nozzle 70 is connected to a high-pressure air source (not shown) through a pipe 74 so that high-pressure air generated by the high-pressure air source can be ejected from the air ejection nozzle 70.
[0030]
  Next, the removal apparatus according to this embodiment12The method for removing the ceramic residue GH in the firing jig 80 will be described.
  In order to remove the ceramic residue GH, as a matter of course, it is assumed that the ceramic residue GH is deposited on the firing jig 80 and the ceramic residue GH is solidified.
  Therefore, prior to the removal of the ceramic residue GH, it is assumed that the firing jig 80 has been used at least once for firing the tile base W in advance. explain.
  In this removing device 12, the transportation of the firing jig 80 is stopped, the rest 82 of the firing jig 80 is rested by the rest means for the rest, and the support 84 of the firing jig 80 is moved by the displacement means for the support body. The ceramic residue GH in the firing jig 80 is removed by a series of steps of displacement and blowing away the ceramic residue GH by an air blowing mechanism.
[0031]
In the process of stopping the conveyance of the firing jig 80, first, when the empty firing jig 80 conveyed on the upper conveyance section 34 of the firing jig conveyor 18 reaches the removing device 12, The operation of the upper conveyance unit 34 of the jig conveyor 18 is stopped, and the firing jig 80 is stopped together with the pallet 32.
The firing jig 80 placed on the pallet 32 is stopped in the removing device 12 by the stop of the upper transport unit 34.
[0032]
Next, the cradle stationary means is actuated so that the cradle 82 of the firing jig 80 does not move when the support body displacing means is actuated.
Specifically, the stationary air cylinder 68 is actuated to advance the advancing / retracting members 58, 58 on both sides toward the firing jig 80 being stopped, but the supporting member 60 provided on the advancing / retreating member 58, the rotating shaft 62, the rotating plate 64, and the stationary roller 66 advance together with the advance / retreat member 58.
As the stationary roller 66 moves forward, the stationary roller 66 comes into contact with the respective corners of the cradle 82 of the firing jig 80, and the cradle 82 of the firing jig 80 is moved back and forth and left and right. In this state, the robot is stopped in a state in which it is not present, and accurate positioning is performed together (see FIG. 4).
[0033]
When the firing jig 80 is stopped by the cradle stationary means, the support displacing means is then operated.
Specifically, the drive motor 44 provided on the portal frame 38 operates to lower the elevating body 42.
When the elevating body 42 is lowered, the pressing roller 54 provided on the slide body 50 reaches a position facing the back surface of the support 84 of the firing jig 80 that is stationary.
Next, the slide air cylinder 52 provided in the elevating body 42 is operated, and the slide body 50 is slid in a direction that coincides with the conveying direction of the firing jig conveyor 18.
As the slide body 50 slides, the pressing roller 54 contacts the back surface of the support body 84 and further presses the back surface of the support body 84.
Since the insertion part 86 of the support body 84 is inserted into the insertion groove 88 that allows the inclination of the support body 84 to be displaced within a predetermined range, the support body 84 is pressed by the pressing of the support body 84 by the pressing roller 54. The insertion groove 88 is used as a fulcrum to be displaced from the inclined state to the standing state (see FIG. 5).
At this time, even if the ceramic residue GH solidified after firing is present in the insertion groove 88 of the cradle 82, the stress due to the displacement of the support 84 acts on the solidified residue GH solidified. The system residue GH is peeled from the insertion groove 88 of the cradle 82.
As the support 84 is displaced from the inclined state toward the standing state, a force that moves the support 82 through the support 84 in the direction opposite to the conveying direction acts on the support 82. As a result, the cradle 82 of the firing jig 80 does not move.
When the support 84 of the firing jig 80 is sufficiently displaced, the slide air cylinder 52 operates to return the slide body 50, and the pressure roller 54 returns to the original position as the slide body 50 returns. .
