Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a production line system for white tiles for smoked roof tiles that is suitable for manufacturing smoked roof tiles with smooth surfaces and is capable of manufacturing white tiles with a smooth surface through a series of mechanical processes.

In general, smoked roof tiles have a graphite carbon film formed on their surface through the smoking action, and are prized as high-class roof tiles due to the unique smoked silver-like luster and brightness of this film, but the manufacturing process requires advanced technology. It takes time and effort,
In particular, at the stage of obtaining white tiles before firing, it is necessary to keep the surface of the base tiles smooth. Conventionally, this work was done manually by polishing each tile with a trowel, resulting in very poor work efficiency. ,
This was one of the reasons why smoked tiles were expensive.

In view of these drawbacks, the present invention has been developed to include a step of extruding and press-molding raw tiles from a clay kneading machine and placing them on a pallet and transporting them to a moisture control room, and a process in which a moisture-containing material suitable for polishing the tiles is placed in the moisture control room. The smoking process consists of the following steps: adjusting the moisture content of semi-finished tiles, removing the semi-finished tiles from a pallet and mechanically polishing them, and transporting the polished semi-finished tiles into a drying room to obtain white tiles. An embodiment of the present invention will be described below based on the drawings, with the aim of solving the above-mentioned drawbacks by providing a production line system for white tiles for tiles.1 is a production line for white tiles _W3 for smoked roof tiles. and
At its base point, a clay kneading machine 2 for extrusion molding the rough ground for tile molding, and a press molding machine 3 for pressing the rough ground discharged from the clay kneading machine 2 are installed in series, and these kneading machine 2, press molding machine There is a trolley C on the side of 3.
A running line having a running track is arranged in parallel in the order of a loading/unloading line 4, a humidity control line 5, and a drying line 6 from the front, and each line is interconnected at both ends by a connecting track 78, A traverser 910 running within the connecting track 78 is configured to transport the cart C between each line.

Reference numeral 11 denotes a loading device disposed across the front of the press molding machine 3 and the loading/unloading line 4, which loads the raw tiles _W1 molded by the press molding machine 3 by appropriate transfer means. The pallets P are arranged and placed on a pallet conveyor 12 disposed in the middle of the loading/unloading line 4.

Reference numeral 13 denotes a stacking device disposed in front of the loading device 11, and is configured to stack pallets P on which raw tiles _W1 are placed in multiple stages on a waiting cart C, so that the pallets P are stacked. The carts are sequentially moved toward the connecting track 7 and are transferred to the humidity control line 5 or the drying line 6 by the traverser 9.

Next, the humidity control line 5 is composed of a tunnel-type moisture control chamber 14, in which a moving fan is arranged and hot air is supplied as needed.

Further, the drying line 6 is constituted by a tunnel type drying chamber 15 in which two rows of carts C are accommodated and transferred in parallel.

Reference numeral 16 denotes a separation device disposed at the rear of the loading/unloading line 4, which performs an operation opposite to that of the loading device and sequentially separates and transfers the pallets P stacked on the cart C onto the pallet conveyor 12. In addition, a loading/unloading device 17 is disposed in the middle of the conveyance path of the pallet conveyor 12 to separate the semi-finished tiles _W2 , which have been adjusted to a predetermined moisture content in a moisture control room, from the pallet P one by one. Further, between the loading/unloading device 17 and the loading device 11, a conveyor 18 for transferring the separated semi-finished tiles _W2 to the loading device 11 is arranged in parallel with the pallet conveyor 12. Halfway through the conveyance path of 18, half-baked tiles are removed by a mechanically controlled trowel.
Polishing device 1 that polishes the surface of W ₂ to make it smooth
9 is arranged.

Next, the flow of the manufacturing line system for white background for smoked roof tiles according to the present invention will be explained. The rough ground extruded by the clay kneading machine 2 is molded into a predetermined shape by the press molding machine 3 to become the raw roof tile _W1 . Raw tiles just after forming
W ₁ has a moisture content of approximately 20%, and even if the surface is polished in this state, it is not possible to obtain white tile W ₃ with a smooth surface. This is because, in the process of drying a molded particulate material with a high water content, when the water moves to the surface, the fine particulate components move inward, and as a result, the coarse particulate components are pushed up toward the surface. This is because the surface of the molded product has the property of being roughened due to this coarse particle component, and therefore, polishing the surface is necessary until the moisture content of the raw tile W ₁ is reduced to such an extent that there is no movement of particles within the raw tile W1. It will not be effective if it is not done when it has decreased.

Next, the press-formed raw tile W ₁ is loaded into the loading device 1.
1, a predetermined number of pallets are sequentially transferred onto the pallet conveyor 12 onto waiting empty pallets P, and the transferred pallets P are sequentially advanced by the pallet conveyor 12 and reach the position of the stacking device 13. The pallets P are stacked at predetermined intervals on a waiting cart C at that position, and the carts C loaded with pallets P move forward one by one until reaching the connecting track 7, where they are placed one by one on the traverser 9.

Then, by the operation of the traverser 9, the cart C loaded with the raw tiles _W1 is moved to the entrance of the moisture control chamber 14 of the humidity control line 5, and is carried into the moisture control chamber 14 one after another.

The trolley C is retained in the moisture control room 14 for approximately 8 hours, during which time it is appropriately blown by a moving fan and hot air to maintain a moisture content of approximately 14 to 16%, which eliminates the movement of component particles of the raw tile _W1 . dried,
A dry half-baked tile _W2 suitable for subsequent polishing operation is obtained.

The press-molding operation of the raw tile W ₁ is interrupted when the moisture control chamber 14 is filled with the raw tile W ₁ , and the molding and humidity control operations are alternately repeated at approximately half-day intervals.

Next, the trolley C loaded with half-baked tiles W ₂ whose humidity has been controlled in the moisture control room 14 is placed on the traverser 10 waiting on the connecting track 8 on the exit side, and by the operation of the traverser 10, it is moved to the loading/unloading line. The pallets P stacked on the cart C by the separating device 16 are transferred one by one onto the pallet conveyor 12.
The unfinished tiles _W2 on the pallet P are transferred one by one onto the conveyor 18 by the unloading device 17, and the empty pallets P are transferred to the pallet conveyor 18. 12 to the loading device 11 side.

During the process of conveying the semi-finished tiles W ₂ onto the conveyor 18 to the loading device 11, the tile surface is polished by the polishing device 19 to give it a smooth surface, and then conveyed to the loading device 11. Ru.
After reaching the loading device 11, they are transferred onto a pallet P in the same way as the raw tile _W1 was transferred, and the pallet P on which the semi-finished tiles _W2 are placed is stacked on the cart C by the stacking device 13. , the cart C is transferred onto the traverser 9.

The cart C transferred to the traverser 9 is now moved to the entrance of the drying chamber 15 in the drying line 6,
They are sequentially carried into the drying chamber 15 for final main drying, and the dried white tiles W ₃ are carried together with the trolley C, and are transferred to the traverser 10 to the storage section 20 for the next process. It is transported.

In short, the present invention includes a step of placing the green tile W ₁ extruded and press-molded from the clay kneading machine 2 on a pallet P and transferring it to the moisture control chamber 14, and a process suitable for polishing the tile in the moisture control chamber 14. A process of adjusting the moisture content, a process of unloading the moisture-adjusted half-baked tiles W ₂ from the pallet P and mechanically polishing them, and carrying the polished semi-baked tiles W ₂ into the drying room 15 to dry the white tiles. It consists of the process of obtaining tiles _W3 ,
During the series of processes from molding to drying, raw tiles
W ₁ can be obtained as a half-baked tile W ₂ whose humidity is adjusted to the optimum condition for surface polishing, and since the semi-baked tile W ₂ is all continuously adjusted and homogenized under the same conditions, mechanical The surface of all products can be given a uniform, smooth finish without any variation even through thorough polishing operations, and all such operations are performed automatically in a series of steps, resulting in high-quality smoked roof tiles.
