[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete panel product placing table which requires steam curing treatment, and a manufacturing control method for the product.

[0002]

2. Description of the Related Art In houses and high-rise buildings, ALC panels (panels of lightweight expanded concrete products) are often used as wall materials, roof materials or floor materials. This ALC panel is manufactured by curing a semi-finished product having a preset size and semi-plasticity (state not cured to a hardness assumed in advance, the same applies hereinafter) by steam curing treatment.

A method of manufacturing the above ALC panel will be described. First, a foam concrete raw material is prepared. At this stage, a lot number as a production unit is given and a plurality of types of ALC panels to be produced from the lot are assigned.
Information such as the lot number and the specifications of the ALC panel manufactured from this lot is presented on the manufacturing card in advance and managed by the host computer. This manufacturing card is printed on paper, stored in a card case provided on the semi-finished product carrier, or manually finished from the reinforcing bar process,
Progress to the inspection process in synchronization with semi-finished products. Then, a large-sized block-shaped concrete block is manufactured from the above-mentioned raw material, and is carried into the cutting device together with the manufacturing card. Therefore, in the concrete block carried into the cutting device, the size, number, etc. of ALC panels to be sampled from the block are preset.

The concrete block has semi-plasticity and can be cut with a piano wire.
For this reason, a plurality of piano wires that can be set to desired dimensions are arranged in the cutting device, and the piano wires are set in accordance with the preset dimensions of the ALC panel to cut the concrete block. , Manufacture multiple ALC panels with semi-plasticity. And as shown in FIG.
A lot number 52 is imprinted and displayed on the end of any one of the plurality of manufactured ALC panels 51, and a manufacturing instruction described in comparison with a manufacturing card is manually input to a host computer.

Cut in the above cutting process and lot number 52
A plurality of ALC panels 51 marked with are placed on the product mounting table 54 to which the identification number 53 is given in advance, and are conveyed to the curing step together with the manufacturing card. In this curing step, the manufacturing card attached to the product mounting table 54 is removed and carried into the steam curing apparatus (autoclave), and the plurality of ALC panels 51 placed are subjected to curing processing under preset processing conditions. To cure. After that, the product placing table 54 on which the plurality of cured ALC panels 51 are placed is taken out from the autoclave, and the manufacturing card is attached to the product placing table 54 and the product is conveyed to the finishing step. In the finishing process, we perform predetermined processing based on the manufacturing card,
Finally, an ALC panel having preset dimensions and hardness is manufactured.

A immediately after cutting the concrete block
Since the LC panel is semi-plastic, the accuracy of the product carrier used when loading it into the autoclave, the accuracy of the carrier that mounts the product carrier, the accuracy of the rail that serves as the carrier path for the carrier, and the steam Changes in various curing conditions and other conditions have a significant effect on the quality of the final product. For this reason,
It is an important point in quality control to strictly control the usage history of autoclaves, product platforms, trolleys, etc. used for each lot.

As described above, since there is a close relationship between the management of the usage history of the product placing table and the quality control of the ALC panel, at present, the identification number is written on the product placing table with paint and the product is carried into the autoclave. At this time, the operator collates the identification number with the lot number and registers them in the product quality control database.

[0008]

As described above, since the information in each process is manually input by the operator, it is difficult to eliminate human input errors. Also A
In the process of manufacturing LC panels, AL with semi-plasticity is used.
Since a semi-finished product of C panel is accompanied by a step of performing high-temperature and high-pressure steam treatment, it is impossible to endure such a severe use condition with a paper which is an ordinary information recording means. Therefore, automation of the manufacturing process, There is a problem that it is impossible to achieve unmanned operation.

It is an object of the present invention to provide a product stand for concrete-based panels equipped with a recognition means capable of withstanding high temperature, high pressure and high humidity, and to provide a method for manufacturing and controlling concrete-based panel products.
