BACKGROUND OF THE INVENTION
The present invention relates to a management device for a secondary vulcanization furnace that performs a secondary vulcanization treatment of an elastomer product.
[0002]
[Prior art]
For example, in the manufacturing process of an elastomer product such as an O-ring, first, a raw material such as a polymer and a compounding agent such as a plasticizer and carbon black are mixed and kneaded to generate a dough.
Subsequently, in order to make the obtained dough into the shape of a product, it is put into a mold and molded by applying heat and pressure. At this time, by applying heat, the physical properties of the elastomer product are changed by vulcanization, but if the heat is applied for a sufficient time, the physical properties of the elastomer product become appropriate values.
However, if the heating time is long, the production efficiency of the product is lowered. Therefore, the elastomer product is taken out from the mold when the physical properties of the elastomer product change to some extent.
Next, after the above molding step, in order to further optimize the physical properties of the elastomer product, the elastomer product taken out from the mold is put into a secondary vulcanization furnace for exposure to hot air, and the secondary vulcanization furnace is used. A secondary vulcanization process is performed to optimize the physical property value of the elastomer product by secondary vulcanization by heating the elastomer product for a predetermined time.

Further, the furnace state monitor file 23C is updated (step S36).
Further, information indicating that the secondary vulcanization process has been completed is transmitted to the barcode reader 11 and displayed on the display unit 12.
The operator can take out the processed elastomer product from the secondary vulcanization furnace by looking at the completion information.
[0072]
As described above, according to the present embodiment, in the elastomer product in which the product is difficult to distinguish from the form, the product is indirectly selected by the barcode reader 11 instead of directly looking at the product. Thus, it is possible to reliably prevent mistakes that erroneously put elastomer products having different secondary vulcanization conditions into the same secondary vulcanization furnace at the same time.
In addition, according to the present embodiment, it is possible to prevent the occurrence of a problem in which similar products can be put into the same secondary vulcanization furnace and mixed and cannot be separated.
Furthermore, according to this embodiment, it is possible to reliably prevent setting errors in the operating conditions of the secondary vulcanization furnace.
In addition, according to the present embodiment, by creating a secondary vulcanization record file for each elastomer product, production management becomes easy, product manufacturing information after product shipment can be stored, and any defects are If this occurs, the cause can be easily identified by referring to the secondary vulcanization record file.
