<p>Vessels 2 on a conveying rail 4 are supported by a back guide 8 and are intermittently conveyed by a transfer rake 6. A number of filling nozzles 28 which corresponds to a number of vessels 2 are installed at a filling station F, and the conveying rail has a portion 4A which is elevatable. Metering receptacles 12 connected to load cells 16 are disposed in a manner corresponding to respective filling nozzles 28. These metering receptacles 12 do not contact vessels 2 when the conveying rail portion 4A is raised, but support the vessels when the conveying rail portion 4A is lowered, allowing a mensuration of the weight of vessels 2 by the load cells 16. During a normal filling operation, the conveying rail portion 4A is maintained in its raised position to convey the vessels 2 and performs a filling operation. During a sampling operation, the conveying rail portion 4A is lowered to place vessels 2 on the metering receptacles 12 to perform a mensuration while performing a filling operation. A sampling operation can be performed in a reduced length of time using a simple construction.</p> |
