ABSTRACT:
In a core blowing machine, a core collecting device including a plurality of core collecting trays is provided, which is positioned at a core removal area of the machine and comprises a support bed on which a first set of guides is provided for guiding a carriage in a longitudinal direction thereof. A frame common for all core collecting trays is integrally connected to the carriage. The frame has a second set of guides which are transversal to the first set. A slide block is positioned on each pair of transversal guides and a tilting support holding the corresponding tray is fitted on each slide block. A tilting cylinder is provided for each tray, which is connected between the slide block and the support. A displacement cylinder for the slide blocks, which connects the latter to the frame, and a further cylinder for the displacement of the carriage, connecting the carriage to the support bed are further provided so that each tray, and consequently each core, may be displaced longitudinally, transversally and tilted from a horizontal position to a vertical position.
