2. Description of the Related Art A Styrofoam molded article is manufactured by using a pair of molding dies, which are a movable mold and a fixed mold, to pre-expand expandable thermoplastic resin particles (beads) or to close them without pre-expanding. Although so-called in-mold foam molding is performed fully automatically, after filling the cavity in the molding die, injecting steam to heat-mold and then cooling, opening the mold and taking out the molded product after mold release, The molded articles taken out of the mold were generally manually collected and aligned.

However, such work of taking out and aligning the molded products has a problem in terms of work efficiency, and the molded products are released from the mold by using a vacuum suction device configured to be movable up and down or left and right immediately after the mold is opened. Then, it is transferred and stored in a magazine rack (see Japanese Patent Laid-Open No. 62-270323), or it is movable in the horizontal direction and vertically moved to an endless conveyor having a suction device to stack and align the molded products. A system in which devices are combined (see Japanese Patent Application Laid-Open No. 63-209823), a reversing mechanism for reversing one of the sequentially conveyed products and facing the other aligned products face-to-face, and controlling the reversed products. A product alignment table that stocks products arranged as partition ends by abutting on a plate, and an automatic conveyance device that is arranged opposite to the product alignment table and includes an extrusion mechanism for extruding products Method of automated removal from the mold, the product recovery that are released from the molding die deployed to the movement position of the product holding member for holding the molded article (JP-A-2-57
No. 512), etc. have been proposed.

However, since each of these proposed means is practically difficult, various problems are recognized. Therefore, further study is added, and an apparatus in which the mechanism for taking out and aligning and accumulating molded articles is continuously automated is proposed. It was previously proposed by the applicant. Then, the applicant then automatically took out the foamed resin molded product molded by the molding device from the molding device to carry out the drying process subsequent to the above-mentioned device, and carried out the stacking alignment, and the stacking alignment. When a molded product reaches a predetermined amount, a continuous processing system is proposed in which the process of automatically conveying the molded product into a drying device and drying it is continuous and combined, and a foamed resin is used as a device for the system. An automatic take-out and aligning device for molded products and a drying device with a built-in belt conveyor for transporting the molded products are installed continuously.When the number of molded products aligned by the automatic take-out and aligning device reaches a predetermined amount, automatic In the above, there was proposed a device configured to feed the molded product into a drying device. On the other hand, a device for stocking dried foamed resin moldings, arranging them side by side on a stock table, and pushing them all together into a synthetic resin film bag with the bag mouth held open, is also being considered. Attempts have also been made to continuously couple this device to the continuous processing system.

[0005]

However, when the transfer mechanism and the wrapping device are continuously arranged following the above-mentioned molded product stacking and arranging device, the installation area is long in the longitudinal direction because of the arrangement of the devices. However, a huge building area is required, and the economic burden becomes large, which is a major obstacle to continuous equipment.

The present invention pays attention to the problem in the arrangement of such a continuous device, and in particular, in the arrangement of the devices, the effective use space is formed to secure the work use area, thereby substantially reducing the economic burden on the building. The purpose is to reduce.
