Abstract

PURPOSE:To shorten the operating time for molding tile stock by housing many pans on which the tile stocks after molding are successively placed in many stokers in a multistage-shape and feeding the pans to a calcination kiln from the stockers according to calcination velocity. CONSTITUTION:In case of continuously calcining tile stocks (a) successively molded 2 in a calcination kiln 3, many pans (b) placed with the stocks (a) are held in many stockers 9 previously prepared in a multistage-shape. The respective stockers 9 housing these pans (b) are stocked in a stocking place and the pans (b) placed with the stocks (a) are drawn out from the stockers 9 according to the calcination capacity of the calcination kiln 3 and fed to this kiln 3. Therefore the molding capacity of the stock (a) with a tile press 2 can be made large regardless of the calcination capacity of the kiln 3. For example, even when the kiln 3 is operated for 24 hours per day, the molding operation time of stock (a) can be drastically shortened to far below 24 hours and therefore working burden can be lightened without performing midnight working in the molding operation of stock (a).

When manufacturing tiles, the empty stocker 9 in which empty trays are placed in each storage shelf 30 in advance is transferred to the empty stocker transport conveyor 21.
First, the tile press 2 forms a large number of tile bases a one after another, and the tile bases a are conveyed one after another by the tile conveyor 5, and are subjected to any known work, such as chamfering, on the tile conveyor 5. After being glazed, the mounting device 7 transports the tile material a to the take-out position.Next, the mounting device 7 adsorbs and takes out the tile material a on the tile transport conveyor 5. The tiles are transferred one after another onto the empty trays supplied to the tile receiving section 6c. When a predetermined number of tile blanks a are loaded onto the empty tray, the actual tray is transferred to the tray conveyor 6.
As shown in FIG. 1, empty saucers are sent out by the real saucer conveyor 6a and temporarily docked as shown in FIG. The above operation is repeated.

Next, in the stock-in device IO, the electric motor 52 of the conveyor drive device 50 is operated in advance to rotate the roller 49 of the roller conveyor 47 in the direction of arrow A in FIG.
In this state, the empty stocker 9 on the empty stocker transport conveyor 21 is sent onto the roller conveyor 47 by the stocker replacement conveyor 22, and as a result, the empty stocker 9 is placed on the roller conveyor 47. After that, the operation of the electric motor 52 is stopped. Further, the hydraulic cylinder 55 operates to lower the lifter 44, and the uppermost storage shelf 3 in the empty stocker 9 on the roller conveyor 47
When the top surface of the container 0 reaches approximately the same height as the top surface of the tray conveyor 6, the operation of the hydraulic cylinder 55 is stopped and the lowering of the lifter 44 is stopped.

Next, the pneumatic cylinder 68 of the roller drive device 37 is operated to move the transverse moving body 57 forward toward the empty stocker 9, and as a result, the chuck 71 of each roller drive shaft 70
grips the ends of each roller 32 of the uppermost storage shelf 30 and is integrally coupled. Thereafter, the electric motor 74 of the rotating device 60 is operated to rotate each roller drive shaft 70 in the convex direction of the arrow in FIG. 9, and each chuck 71 rotates each roller 32 in the same direction. As the rollers 32 rotate, the empty trays placed on the rollers 32 are sent out from one opening 29 of the empty stocker 9 to the empty tray conveyor 6b of the tray conveyor 6 and stocked therein. In addition, while each of the rollers 32 is being rotated, the actual trays stocked in the actual tray conveyor 6a of the tray conveyor 6 are transferred from the other opening 29 to the stocker instead of sending out the empty trays. It is sent onto the storage shelf 30 of No. 9. The actual saucer is completely placed on the storage shelf 30! When this occurs, the operation of the electric motor 74 is stopped and the rotation of each roller 32 is stopped, and the actual tray is moved to the top storage shelf 3.

Remove from 2.

Next, the hydraulic cylinder 55 operates again to raise the lifter 44 by the height pitch of the storage shelf 30, so that the upper surface of the second storage shelf 30 from the top in the stocker 9 is at the same height as the upper surface of the tray conveyor 6. At this point, the operation of the hydraulic cylinder 55 is stopped to stop the lifter 44 from rising. The height of the lifter 44 for each stage of the storage shelf 30 is determined mechanically by a detection mechanism such as an encoder or a phototube. Thereafter, the roller drive device 37 operates again to transport the empty trays from the stocker 9 and feed the actual trays into the stocker 9. The feeding and feeding of empty trays to the stocker 9 is performed every time the loading device 7 fully loads the tile base material a onto the empty tray.

Next, an empty tray is sent out from above the lowermost storage shelf 3G in the stocker 9, and a real tray is sent onto the storage shelf 30 in exchange, so that all the storage shelves 30 of the seven cars 9 are When the actual tray is housed in the container, the hydraulic cylinder 55 is moved with each chuck 71 detached from each roller 32.
is activated to raise the lifter 44 to its original highest position, bringing the roller conveyor 47 to approximately the same height as the stocker exchange conveyor 22.Next, the electric motor 52 is activated again to raise each roller 49 of the roller conveyor 47. As a result, the actual stocker 9 on the roller conveyor 47 is sent onto the stocker replacement conveyor 22, and then conveyed onto the actual stocker transport conveyor 20 and temporarily docked. Thereafter, the empty stocker 9 is sent onto the lifter 44 again, and the above operation is repeated.

On the other hand, in the stockout device 13, the actual stockers 9 stocked on the actual stocker transport conveyor 20 are sent by the stocker replacement conveyor 23, and the actual receiving trays accommodated in the respective storage shelves 30 of the actual stockers 9 are The trays are fed one by one onto the tray conveyor il, and empty trays are fed onto the storage shelf 30 in exchange by the tray conveyor 12. By repeating the above operation, all the storage shelves 30 of the stocker 9
When an empty tray is accommodated in the tray, the empty stocker 9 is sent out from the storage space 78 onto the stocker exchange conveyor 23, and then conveyed to the empty storage tray transport conveyor 21 and temporarily stockocked. Thereafter, the actual stocker 9 stocked on the actual stocker transport conveyor 20 is moved again to the stocker elevating space 7 of the stockout device 13.
8, and the above operation is repeated.

The actual trays sent out from the stocker 9 by the stock-out device 13 are conveyed to the tray conveyor 11, where they are temporarily docked, and midway through, they are passed through a dryer 14 and dried. Thereafter, the actual saucer is transported to the firing kiln 3 and fired. Thereafter, the fired actual trays are sent by the tray conveyor 12 to a take-out position by the unloading device 16, and the unloading device 1
6, the fired tiles on the tray are transferred onto the tile conveyor 15, and the tile conveyor 15
The products are transported by the machine and subjected to post-processing such as stocking. The empty trays from which the tiles have been unloaded are transported by the tray conveyor 12 from the take-out position by the unloading device 16, temporarily docked, and then stored in the stocker 9 again.

Firing in the firing kiln 3 is normally carried out continuously for 24 hours every day, and actual trays are continuously supplied into the firing kiln 3 by a tray conveyor 11. In contrast, the capacity of Tile Breath 2 for forming and glazing the tile base a has been increased so that it can process the amount necessary for 24-hour firing in about 8 to 16 hours a day, and the work is carried out at night from 8 to 16 hours a day.
If the interruption is interrupted for 6 hours, the actual saucers that increase due to the difference between the molding and glazing work capacity and the firing capacity will be compactly stocked in multi-tiered form in the stocker 9, and the molding and glazing work will be interrupted. 8-16 at night
It is sent to the firing kiln 3 during the time, and the firing takes place 24 times a day.
Continuous time. In addition, firing trays are generally made of refractory material and are easily damaged, making it difficult to stack them in large numbers. Since the stock of trays can be transported in a small space, damage to the trays can be prevented during transportation.

〔Effect of the invention〕

As described above, in the present invention, when firing the tile substrates a that are successively formed by the tile press 2, the tile substrates a to be formed are placed one after another on a large number of transport trays, The kiln 3 fires those many saucers one after another.
By passing the tile material continuously through the tile substrate, the tile base material a can be fired efficiently.

Further, when the tile substrates a formed one after another by the tile press 2 are fired continuously in the firing kiln 3, first, the saucers on which the tile substrates a formed by the tile press 2 are placed are placed in a large number of stockers prepared in advance. Each stocker 9 containing the trays 9 is stored in a multi-tiered manner, and each stocker 9 containing the trays 9 is stocked at a stocking location, and the trays carrying the tile base material a are transferred from the stocker 9 in the stocked state to the firing kiln 3. Since it is drawn out and supplied to the firing kiln 3 in accordance with the firing capacity, the molding capacity of the tile base a by the tile press 2 can be increased regardless of the firing capacity of the firing kiln 3. For example, when the firing kiln 3 is operated for 1824 hours However, the molding time for the tile base a can be significantly shortened from 24 hours, and as a result, the work load can be lightened, such as eliminating late-night work from the molding work for the tile base a.

In addition, in the present invention, as described above, the saucer plate on which the tile base material a is placed is placed in the stocker 9 and stocked, and the saucer plate on which the tile base material a is placed is taken out from the stocker 9. Even in the case where the empty saucer is placed in the stocker 9, and when the saucer is put into the stocker 9, the empty saucer is taken out from the stocker 9 and the saucer is placed in the stocker. When taking out the empty trays from the stocker 9, empty trays are placed in the stocker 9 in exchange, and the stocker 9 containing those empty trays is also stocked. This can be carried out by transport, which has the effect of simplifying the transport of empty trays.
