コンクリート製品成形装置、コンクリート製品の成形用型枠箱、およびコンクリート製品成形装置における型枠の位置合わせ方法
Document Type and Number:
Japanese Patent JP4249275
Kind Code:
B2
Abstract:
A mold box is flexibly mounted to a product forming machine having upper and lower vertically displaceable beams. A feed drawer dispenses concrete material into the mold box while a vibration system vertically vibrates the mold box while dampening horizontal vibration. The vibration system is driven by a single drive shaft that actuates first and second vibrator rods while at the same rotating a counter-weight in a counter-rotating direction. A set of alignment brackets lock the mold box into a predetermined aligned relationship while being mounted in the product forming machine. The bottom side of each mold box is mounted to the product forming machine in the same relative position to reduce machine readjustments. A set of telescoping legs hold the feed drawer assembly variable distances above the mold box. A unitized pallet feeder quickly moves pallets one at a time from an on-deck position to a receiving position underneath the mold box.
