In a molding device applied to molding a molded product, for example, a calcium silicate molded product, the molding device 2 is equipped with a plurality of t-ruds arranged in one direction, and the molded product is multi-fed. There is a very large interval between them, which corresponds to the parallel interval of t-led.

Therefore, until the parallel state 1 when the molded product is sent out,
In other words, if a vacuum suction type transfer device is applied to load onto a transport shelf, a large unloaded area will be left on the shelf, making loading extremely inefficient and reducing productivity. Also, calcium silicate molding When drying molded products by heating while they are still stacked on a shelf, there is a problem that the thermal efficiency in the drying process decreases. In this case, it may be possible to use apricots or mechanical force to load the molded products between the molded products, but this not only takes time but also causes problems such as damage to the molded products during loading. arise.
