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. It is a container-transporting device for holding and transporting a square-cylindrical containerby a container holderformed between container-transporting meansanddisposed to face parallel with each other, wherein the container conveying meansandare equipped with: a number of blockshaving a holding partconstituting a part of a container holder; outward block-support membersand homeward block-support members, arranged by extending in the conveying direction, for supporting a number of blocksin a movable condition along the conveying direction; a first transfer meanscapable of sequentially transferring the blocksthat have been conveyed while being supported by the outward block-support membersto the homeward block-support members; a second transfer meanscapable of sequentially transferring the blocksthat have been conveyed while being supported by the homeward block-support membersto the outward block-support members; and a block delivering meanscapable of delivering and conveying the blocksso that each blockcan be circulated.

Chainless container-transporting device

A drive device comprises an air cylinderfor causing an operating member for a packaging operation to perform a reciprocating motion, a sensorfor detecting the cycle velocity or time of the air cylindera control valvefor controlling the pressure or flow rate of the fluid to be supplied to the air cylinderand an a sequencerfor setting a reference value SV corresponding to the cycle velocity or time of the air cylinderreceiving a value PV detected by the sensoras 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 valvebased on the calculated valve opening degree.

Drive device for packaging machine

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.
