Plastic bottle, a device for the packing and unpacking and method of packing and unpacking plastic bottle

摘要

The retractable plastic bottle has a bottom (25) provided with openings (26) which may be straight or displaced from its lower edge at least. The bottle wrapping and packaging machine consists of a conveyor (3.1) for the supply of unpackaged bottles (4.1) and conveyor (3.2) for dispensing packaged plastic bottles (4.2). Furthermore, the device comprises a rotary table (2) on which an inner holder (7), a vertical pneumatic cylinder manipulator (15) with vacuum suction cups (6), a horizontal pneumatic manipulator (22) with a self head ( 13) and a thermal chamber (10). The rotary table (2) is equipped with a pump (12) and a compressor (18) is assigned to the device. When packing the plastic bottle, move the unpackaged bottle (4.1) to the inner holder (7), the foil sleeve (13) is removed from the container (5) and the vacuum is drawn into the unpackaged bottle (4.1). Then the bottle (4.1) is transferred to the thermal chamber (10), where the foil sleeve (13) is shrunk and its waterproof attachment. The bottle (4.2) is transferred to the conveyor (3.2) and to the waste line (19). When unpacking the bottle, the opposite is done, i. e. the packaged bottle (4.2) is transferred to the inner holder (7) and the air pressure is transferred to the waste pipe (19).
