In the conventional molding operation, the products of the manufactured molded products must be manually handled and collected, and it is complicated and time-consuming, and the products are not uniform even after being conveyed. However, it is not satisfactory because it requires alignment work before shipping and workability is delayed, and in particular, the products have various sizes and shapes and are difficult to handle, and the products are contaminated or damaged during the delivery work. However, there is a problem in that it takes a lot of time to prepare for changing the setting conditions and the workability is deteriorated. In the present invention, in order to properly eliminate these conventional drawbacks, the handling of the product separated from the molding die is automated,
The product take-out / accommodation processing time can be greatly shortened, the package can be easily packaged for easy handling, and the setting conditions associated with product changes can be easily handled without causing stains or damage to the product. The present invention intends to provide a method for taking out a foamed resin molded article and a processing apparatus therefor in a simple and compact form, which is capable of highly safe automatic processing work.
