Description

[Detailed Description of the Invention] The present invention relates to an apparatus for continuously stacking molded products taken out of a press at a high production speed into vertical pallets.

Conventionally, the molded products taken out of the press were moved by a continuously moving belt conveyor, etc., and then stacked and bundled manually for transport.

For this reason, the indexing time of M such as presses depends on the time required for manual labor, and it is unreasonable that in order to shorten the indexing time and improve productivity, it is necessary to increase the number of manpower accordingly.

Furthermore, if there is a risk of the molded product being deformed when stacked flat, or if vertical stacking is more suitable for transportation, the posture of the molded product must be changed, which increases the amount of time required for manual labor. This results in a situation where the mechanical performance of the press or the like cannot be fully demonstrated due to the long length.

This invention was developed with the aim of mechanizing the handling, changing of posture, and transport of molded products, thereby saving labor and improving productivity. A fork device is used to deliver the molded products to the lifter, and after a predetermined number of molded products are picked up, the multiple molded products are palletized and loaded onto a panel transport device.
