It is a method for producing a food-filled and sealed container having a high product value, in which a container lid made of resin is not deformed after sealing. In this method for producing a food-filled and sealed container, after a food is filled in a container body () made of thermoplastic resin, the container is sealed by heat sealing a container lid () made of thermoplastic resin, and the container body () and/or the container lid () have sealing surfaces () provided with a concavity or convexity.

The present invention provides a liquid filling method capable of filling liquid into containers at a rate as high as 3500 containers/nozzle&middot;hour (2 pitch-feed) without causing the problems such as foaming, turbulence of liquid surface and the like inside the container, and a high-speed liquid filling machine used in said method. In said method, liquid is filled into a container that had been intermittently carried in a sequential manner to a filling station by raising and lowering said container, the filling is started when the container is raised before it reaches the upper dead point of raising and lowering, the container is filled with a specified amount of liquid at the upper dead point of raising and lowering, and then filling is continued while lowering the container. It is preferable for the filling to be started before the carrying of the container is stopped, for example, the start of the filling to be advanced 30&deg; to 70&deg; from the upper dead point of raising and lowering in one raising and lowering cycle of 360&deg;. Furthermore, it is preferable for the carrying to be started before the lowering of the container is finished, wherein the start of carrying the container is advanced 40&deg; to 70&deg; from the end of lowering in one raising and lowering cycle of 360&deg;.

Liquid filling method

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.

A conveyor has a rotary encoder for measuring the amount of rotation of a driven sprocket having an intermittently drivable chain reeved therearound, and a processor for processing the measurement obtained by the encoder as operation support operating data corresponding to the amount of rotation of the driven sprocket. The processor determines a reference position of the chain in time series when the chain is moved a distance at a time by intermitting driving, computes the actual position of the chain corresponding to the reference position based on the measurement obtained by the encoder, and computes the deviation of the actual position of the chain from the reference position.

Conveyor

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 liquid filling apparatus comprises an apparatus body having a liquid channel connected at one end thereof to a liquid tank and at the other end thereof to a filling nozzle, a metering cylinder provided in the liquid channel between opposite ends thereof in communication with the ends for causing the liquid to be filled to flow into and out of the liquid channel by strokes of a piston housed in the cylinder, a check valve disposed upstream from the metering cylinder of the liquid channel, and valve opening-closing means for mechanically operating the check valve so as to open the valve during the inflow stroke of the piston and to close the valve during the outflow stroke of the piston.
