A liquid metering and filling lifter for use with different kinds of containers (C) having different heights for moving the container (C) upward and downward with a stroke corresponding to the height of the container (C) in filling a liquid into the container, the lifter comprising a container pushing-up vertical lift rod ( ) disposed below a filling nozzle ( ) above a bed ( ) and extending through the bed ( ), the lift rod ( ) having a container support ( ) fixed to an upper end thereof, a container pushing-down vertical lift rod ( ) extending through the bed ( ) at one side of the lift rod ( ) and having a container holder ( ) fixed to an upper end thereof, and coupling means ( ) disposed below the bed ( ) for coupling the two lift rods ( ), ( ) to make the lift rods movable upward or downward together and uncoupling the lift rods ( ), ( ) to make the lift rods movable upward or downward individually.

Liquid metering and filling lifter for containers

A filling nozzle cleaning device comprises an adaptor having an upward socket connectable to a downward discharge outlet of a filling nozzle disposed above a bed a collecting pipe having a vertical pipe portion communicating with the socket and extending through the bed rotatably and upwardly and downwardly movably, and a drive mechanism for moving the adaptor so as to advance the socket to or retract the socket from below the discharge outlet and connect the socket to the discharge outlet when the socket is advanced. The drive mechanism has a rotary actuator and a fluid pressure cylinder which are connected to the vertical pipe portion below the bed for rotating and upwardly and downwardly moving the pipe portion

Cleaning device for filling nozzles

A packaging machine comprises a movable body having mandrels and intermittently drivable so as to stop each of the mandrels at a process station while carrying containers as fitted around the respective mandrels with a bottom forming portion of each container projecting outward from the mandrel, and a bottom breaker for forming folds in a bottom forming end portion of the container fitted around the mandrel as halted at the process station so as to render the end portion foldable flat. The bottom breaker has first folding means for initially folding the second and fourth bottom panels in two into triangles, and second folding means for subsequently folding first and third bottom panels. The second folding means has an upstream arm movable into pressing contact with the first bottom panel, and a downstream arm movable into pressing contact with the third bottom panel. The downstream arm is provided with a pressure plate at a portion thereof to be contacted with the third bottom panel.

Packaging machine

A heating device for heat-sealing bottom portions of containers has a hot air nozzle 62. The nozzle 62 is positionable as opposed to a bottom forming end portion 14 of a tubular blank 11 of square cross section as fitted around an intermittently drivable mandrel 52 for heating a region of the blank end portion. The nozzle 62 is movable toward or away from the end portion 14 on the axis of the blank 11. The nozzle 62 has orifices 101, 102, 131, 132, 133 directed toward a plurality of parts within the region when the nozzle is positioned close to the end portion. Among the orifices 101, 102, 131, 132, 133 of the nozzle 62, those 101, 131 directed toward the part of the region remote from an extremity of the blank when the nozzle is so positioned have a greater open area ratio than those 102, 133 directed toward the part of the region proximate to the blank extremity when the nozzle is so positioned.

Heating device for heat-sealing bottom portions of containers

A packaging machine having a filling device, a top breaker, a top heater and a top sealer which are arranged along a path of transport of containers. A hot air applicator is disposed between the filling device and the top breaker for eliminating the froth to be produced when containers, each having an upward opening, are filled with contents. The applicator includes a hot air discharge box having a bottom wall, a top wall, a side wall and two air outlets formed in the bottom wall, the air outlets being arranged along the transport path so as to be opposed to the openings of containers from above, and means for supplying hot air to the box. Each of the outlets is covered with a perforated plate, and has an edge portion provided with a downwardly extending annular portion for preventing the hot air from spreading out.
