Abstract: The present invention provides a container-transporting device which fundamentally avoids the problems caused by elongations and the structure of endless chains, which is inevitably created by using endless chains in the container-transporting conveyors for conventional filling-and-packaging machines.

Abstract: A drive device comprises an air cylinder 123 for causing an operating member for a packaging operation to perform a reciprocating motion, a sensor 132 for detecting the cycle velocity or time of the air cylinder 123, a control valve 222 for controlling the pressure or flow rate of the fluid to be supplied to the air cylinder 123, and an a sequencer 201 for setting a reference value SV corresponding to the cycle velocity or time of the air cylinder 123, receiving a value PV detected by the sensor 132 as an input, calculating a valve opening degree so as to reduce the deviation of the detected value PV from the reference value SV to zero and setting the opening degree of the control valve 222 based on the calculated valve opening degree.

Abstract: 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.
