Abstract

PURPOSE:To make the saving of heat energy, and decreasing mounting spaces, and further enable the time of drying and burning to be shortened considerably by inversely placing a green wave which are press-molded by a press line on a pallet, furthermore, transporting the pallet into the preliminary drying chamber of a drying furnace in order to perform preliminary drying. CONSTITUTION:A press line for conducting press molding is placed on the origin of a manufacturing line, and on the one side thereof, press-molded green waves are arranged inversely on a pallet 14, wherein drying lines 8 comprising a multistage drying furnace 9 which serves to divide by metallic partitions 12 the upper stage for drying the green waves into a preliminary chamber 10 and the lower stage into a main drying chamber 11 are displaced in parallel. Thereby the heat energy in the main drying chamber 11 is introduced effectively into the preliminary drying chamber 10 via the partitions 12, and the heat energy is utilized as radiant heat so as to save the heat energy required in drying within the preliminary drying chamber 10. And, by making the drying furnace 9 into a multistage type, it becomes advantageous to the decreasing counterplan of installation spaces; moreover, by drying the green waves in an inverse state on the pallet 14, the contact efficiency with hot air or the like within the furnace is improved.

Description

[Detailed Description of the Invention] [Object of the Invention] The present invention aims to improve the productivity of ceramic products by responding to the differences in operating time of each process when manufacturing shellfish. 'X
This relates to a W construction line system.

Traditionally, as a production line system for ceramic products, the kiln itself reaches temperatures of over 1,000 degrees, and it takes several days to stop and restart the kiln. , on holidays, driving day and night, and because the white fabric manufacturing process such as molding and drying of the white fabric is a regular work operation, there is a possibility of drying, drying, etc. between the white fabric manufacturing process and the baking process The operating hours are different, work is done day and night in two shifts depending on the baking process, and work is done on consecutive days, which has forced a deterioration of the labor environment.

In order to solve this problem, there is a stocking area between the blank fabric manufacturing process and the firing process where drying carts loaded with several hundred pieces of blank fabric are stocked, and a stocking area where firing carts loaded with hundreds of pieces of fired products are stocked. However, in this stocking method, each trolley is very thick and heavy, so it is impossible to load and stock in multiple stages, so a large number of trolleys are required. It is expensive, requires a large amount of space, is difficult to secure a work place, and each cart is heavy, which hinders work such as moving the cart. Due to the use of the above-mentioned trolley, the processing time of the kiln has the drawback that it usually takes more than 40 hours to produce the final product, and the processing capacity is limited.

The present invention utilizes the thermal energy of the main drying chamber to save the thermal energy required for drying in the pre-drying chamber, reduces the installation space, and significantly shortens the drying and baking time. This makes it possible to absorb the difference in productivity and operating time between the firing process and the blank manufacturing process on the stockyard line, allowing the firing furnace to be constantly operated, and to reduce the maintenance of other lines. Continuous production can be carried out without any problems even during inspections, and depending on the amount of stock, it is possible to support unmanned operation at night, etc., and it is also possible to shorten the working hours of workers during daytime operations. This greatly improves productivity, and since both the parent and baking carts are lightweight, it is possible to simplify the equipment used to move the systems between each other. In contrast, it is an object of the present invention to provide a production line system for ceramic products that does not require a large number of large, heavy, and expensive carts, thereby reducing production costs.

Place the upper part on the floor to dry the white space in the pre-drying room lO.
, the lower part is the main drying room 1], and the partition wall 12 made of metal is provided.
Since the drying line 8 consisting of multi-stage drying ovens 9 divided into sections is arranged in parallel, the carcass energy in the main drying chamber 11 is effectively transferred to the pre-drying chamber 10 via the partition wall 12. By using this energy from the carcass as radiant heat, we can save the thermal energy required for drying in the pre-drying chamber 10. Also, by changing the drying oven 9 to a multi-stage type, the installation space is reduced. It is also useful for strategy, and it is also a palette】4
By being able to dry in a lying position in the furnace, the distance between the white backgrounds is smaller than in the conventional method, and the efficiency of contact with the air in the furnace is improved, so it takes less than 1 gram of drying time. It would be possible to significantly shorten the

23 Furthermore, since the firing line 20 consisting of multi-stage firing furnaces 21 is arranged in parallel on one side of the drying line 8, it is possible to perform firing with six trowels lying on the firing cart 25 in the same way as above. This makes it possible to significantly shorten the firing time, and by using a multi-stage system, it is also useful for reducing the installation space.

Further, on the other side of the burning line 20, there is an outlet side E of the burning furnace 21.
A firing carriage moving track 29 is provided which connects the firing carriage moving track 29 to the inlet side F, and above the firing carriage moving track 29 there is a glaze conveyed from the glazing line 47 connected to the drying line 8.

The difference in productivity and operating time between the incineration process and the white background manufacturing process can be reduced by
6 and the product line 1 - Because the blank lQa and the product Wb can be stocked in the storage container 37, the firing furnace 21 can be operated continuously at all times, and it is also possible to avoid having to stop other lines for maintenance inspections, etc. Continuous production can be carried out without any problems even during periods of high demand, and depending on the amount of stock, it is possible to support unmanned operation at night, etc., and during daytime work, workers' working hours can be shortened due to the time required6. This can also be handled.

Therefore, this system can greatly improve the productivity of ceramic products, and also improves the productivity of ceramic products.
Since both of these products are lightweight, the equipment for moving the systems between each other can be made simple, and compared to conventional baking carts, there is no need for multiple large, heavy, and expensive carts. Its practical effects, such as being able to reduce costs, are also important.
