Abstract:
A device for charging the plasticizing unit of an injection molding machine, in particular ram-type compactor for moist polyester, comprising:a feed pipe constructed for connection to the plasticizing unit; a compaction cylinder having a lower end supported by the feed pipe and an upper end; a storage container receiving material for introduction into the compaction cylinder; a compaction ram constructed for movement into the compaction cylinder; a retaining flange securely supported by the feed pipe and receiving the upper end of the compaction cylinder; a drive unit for moving the compaction ram and the storage container between a first position in which the compaction ram is in alignment with the compaction cylinder for allowing the compaction ram to compress the material in the compaction cylinder, while the storage container can be charged with new material, and a second position in which the storage container is in alignment with the compaction cylinder; and a coupling unit for linking the compaction cylinder to the compaction ram.
