Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel method for stocking a large amount of pre-fired articles to be placed in a firing furnace or post-fired articles to be fired.

[0002]

2. Description of the Related Art In recent years, in the industry of mass-producing kiln products using a firing furnace such as a tunnel furnace, it is necessary to provide a step of temporarily stocking the articles to be fired before they are put into the oven or those to be fired out of the oven. The sex is getting higher and higher as the number of holidays increases.

Conventionally, a stocking method therefor is as follows:
A method has been adopted in which a firing cart that travels in a tunnel furnace is used, a product to be fired is stacked on the truck, and the truck is run to an outside line laid on the side of the firing furnace to perform stocking.

[0004]

However, the method of stocking on the firing carriage as described above has a number of problems. First of all, it is necessary to prepare an extra number of firing trucks for stock, and since this firing truck needs to have a heavy structure considering the heat resistance function, the manufacturing cost is high and the outside line for running it is also expensive. In addition, the burden of equipment costs is large.

Also, a large space is required for the stock. It is well known that when firing in a firing furnace, the lower the stacking height of the article to be fired is, the more uniform the temperature distribution among the articles to be fired is, which is preferable for firing. In addition, when the firing carriage is shaped so as to have a large mounting area, the problem of the above space becomes remarkable.

Further, since the firing trolley can be run only on the rails due to its structure, there is a drawback in that workability is poor such that movement is restricted.

There is also a method in which the product to be fired is placed on a soil floor or the like and stocked, but in that case, the product to be fired is apt to be damaged and the yield is poor.

[0008]

The method of stocking a product to be fired in a firing furnace according to the present invention has been completed in view of the above points, and a base plate on which the product to be fired is placed is used in a firing cart. Before firing, it has a large number of stock carts that are assembled with a frame and can be stacked in multiple stages
The baked products of the above with the base plate in the last row of the outside line for stock
Load it on a stock trolley, move it on the outside line, and
When stocked on the stock truck to the stacking position in the front row
In both cases, the product to be fired after firing is the front row of the outside line for stock.
At the loading / unloading position of the
The stock truck is stocked until it is moved up and taken out from the last row of this outside line .

The stock truck may be provided with the identification code of the truck.

Further, the stock truck may be provided with an identification code of the article to be fired loaded on the truck.

[0011]

[Function] The product to be fired before firing is loaded on the stock cart in multiple stages than the stacking stage on the firing cart along with its base plate, and is stocked on it while running to the outside line etc. until the furnace is put into the furnace. It

When firing is performed in the firing furnace and the firing truck is unloaded, the articles to be fired loaded on the firing truck are stacked together in a stack truck in a number higher than that of the firing truck. The articles to be fired are stowed on the stock truck by being transferred to and housed in the stock truck, and running the stock truck on an outside line.

[0013]

As described above, according to the present invention, since the product to be fired together with the base plate is loaded on the stock truck to be stocked, the product to be fired can be provided as if it was placed in a conventional soil floor or the like. It is less likely to be damaged and the yield can be improved. Moreover, since the stock truck can store the products to be fired in multiple stages rather than the stacking stage of the firing truck, the stock truck can be put on the firing truck while being stocked. Compared to the case
The space for stock can be significantly reduced.

As a result, a large amount of stock of the products to be fired can be stored even in a limited space, the number of holidays can be easily increased, and a firing furnace with a low stacking height can be adopted.

Further, it is not necessary to have a large number of expensive firing trucks for stock and to lay an expensive outside wire for running them, while the stock truck is manufactured at low cost because it is formed by assembling the frame. In addition, since the outer line for running such a light stock truck can be made of inexpensive channel steel or angle steel, the equipment cost can be significantly reduced.

It is also possible to load and unload the product to be fired from the firing trolley discharged from the furnace onto the stock trolley, and subsequently load the vacant firing trolley with the product to be fired next and put it in the furnace. By doing so, the time outside the furnace of the baking trolley is shortened, the reduction of the heat held by the trolley is reduced, energy saving effect is obtained, and the work environment is improved because the heat release time outside the furnace is short. To be done.

The stock truck is lightweight as described above. For example, the fixed wheel can be provided on the front wheel and the free wheel can be provided on the rear wheel, and the stock truck can be manufactured in the same structure as that of the handcart. It can be freely moved to any place, improving workability.

If the stock cart is marked with an identification code of the carriage by a bar code or the like, and further with the identification code indicating the type of the article to be baked loaded on the carriage,
Even if it is stored in a three-dimensional warehouse, it can be easily managed by the computer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a wide tunnel furnace in which firing is performed while a firing truck 2 loaded with the articles to be fired a travels on a rail (not shown) in the furnace in an arrow direction. It has become.

A drying furnace 4 is connected to the entrance side of the tunnel furnace 1 through a traverser 3, and a stacking machine 5 for the product to be baked a is installed at the entrance side of the drying furnace 4.

At the exit side of one of the tunnel furnaces 1, a loader 6 for the product to be fired a is installed via a similar traverser 3, and this loader 6 is mounted on the rail of the loader 5 described above. It is connected.

On the side of the tunnel furnace 1, a plurality of outer wires made of a channel steel material or an angle steel material for running a stock truck 7 described later are laid in parallel with each other.

As shown in FIGS. 2 and 3, the stock cart 7 has a frame 9 made of channel steel and angle steel mounted on the upper surface of a base frame 8, and a receiving material 9a is passed over the frame 9 to form a product to be baked a. Also, the base plate b on which it is placed has a structure capable of being housed in three upper and lower stages.

On the lower surface of the base frame 8, wheels capable of running the above-mentioned outer lines are attached, and in particular, fixed wheels are provided on the front wheel side so that the direction can be easily changed and stable running can be expected. Free wheel 11 is used on the rear wheel side. Further, a hand push rod 12 is attached to the rear surface side of the frame 9.

At the front row of the stock line, the loading position A and the loading position B corresponding to the above-mentioned loading machine 5 or the loading / unloading machine 6 are installed, and on both sides of each outside line. A traverser 15 for stock truck 7 having a direction reversing device 14 is laid. The traverser 15 on the left side extends to a three-dimensional warehouse 16.

This embodiment has such a structure. In FIG. 1, the product to be fired a before firing is, as shown by the arrow x,
In the last row of the stock line for the stock, it is loaded on the stock truck 7 in three stages while being placed on the base plate b.
The stock cart 7 moves on the outside line while using the above, and the article to be fired a is stocked on each stock cart 7.

In the case of putting in the furnace, the stock truck 7 loaded with the products to be fired a before firing is sequentially moved from the left side of the outer line in the front row to the loading position A, and the loading machine 5 is used to move the stock truck, for example. Two pieces a to be fired a of 7 together with their base plates b are stacked in one stage on one firing carriage 2.

The stock truck 7 that has become empty continues to move to the loading / unloading position B on the outer line in the front row.

As described above, the baking carriage 2 on which the product to be baked a is loaded passes through the drying furnace 4 and then travels inside the tunnel furnace 1 to be baked. Since they are stacked in one stage, that is, the stacking height is low, the temperature distribution among the products to be fired a in the furnace 1 can be made uniform, and good firing is performed.

When the firing carriage 2 exits from the exit of the tunnel furnace 1, it travels through the traverser 3 to the position of the loading and unloading machine 6,
By the unloading machine 6, the products to be fired a, which have been fired and are loaded on the firing trolley 2, are laid on an empty stock trolley 7 which has sequentially traveled to the unloading position B on the outer line in the front row. The boards b are unloaded. In the case of this loading / unloading, one firing cart 2
Is divided into two stock trucks 7, and each stock truck 7 is stacked in three stages.

The baking carriage 2 on which the products to be baked a are unloaded runs along the rails to the position of the stacking machine 5 and is used for stacking the products to be baked a as described above.

The stock truck 7 loaded with the products to be baked a after baking moves on the outside line while using the traverser 15,
The article to be fired a is stocked on each stock truck 7 and taken out from the outer line in the last row as indicated by arrow y.

When the traverser 15 changes the row of the outside line on which the stock truck 7 travels, the direction reversing device 14 provided in the traverser 15 reverses the direction of the stock truck 7 back and forth, and the stock truck 7 is always turned. The free wheel 11 runs on the outside line in a fixed direction with the rear side coming.

In addition, a stock truck 7 loaded with the products to be fired a
Is transported to and stored in the three-dimensional warehouse 16 by the traverser 15 on the left side as necessary. At that time, the stock cart 7 is marked with the identification code of the cart 7 using a bar code or an IC card, and If the identification code of the product to be baked a placed on the dolly 7 is marked, it can be easily managed by the computer.

As described above, according to the present embodiment, two baking carriages 2 which can be stacked on one baking carriage 2 in one step or the stacked products a to be baked can be stacked up to three steps, respectively. Since the stock truck 7 is loaded on the compact stock truck 7 to perform the stock, the space for the stock can be significantly reduced as compared with the case where the stock is loaded on the firing cart 2.

Further, it is not necessary to have a large number of expensive firing trucks 2 for stock and to lay an expensive external line for running them, while the stock truck 7 has a frame 9
It can be manufactured at low cost because it is formed by assembling the base material 9a and the receiving material 9a, and the outer line for running such a light stock truck 7 can be made of inexpensive channel steel or angle steel, which significantly reduces the equipment cost. be able to.

Further, the firing truck 2 that has been taken out of the furnace is a loading / unloading machine 6.
After loading and unloading the product to be fired a on the stock truck 7, it is moved on the rail and transferred to the loader 5, and is subsequently used to load the next product to be fired a, that is, the firing trolley 2 is Since the time outside the furnace is shortened, the reduction of the heat held by the trolley 2 is lessened, an energy saving effect is obtained, and the work environment is improved because the heat release time outside the furnace is short.

The stock trolley 7 is lightweight and has the same structure as a handcart having fixed wheels 10 on the front wheels and free wheels 11 on the rear wheels. It can be easily removed to any place.
