An apparatus for continuously aspirating a fluid from a fluid source. A vacuum source is operatively connected to a first container forming a first chamber and a second container forming a second chamber. A fluid collection tube provides communication between the fluid source and each of the first chamber and the second chamber. A first level sensor is positioned within the first chamber and a second level sensor is positioned within the second chamber. Upon receiving a signal generated by one of the first level sensor and the second level sensor, a relay responsively exposes a vacuum within one of the first chamber and the second chamber to continuously aspirate at least a portion of the fluid from the fluid source. A shut-off valve is preferably positioned within each of the first chamber and the second chamber to prevent communication between the vacuum source and the corresponding chamber with a fluid level within the chamber at a fluid level setpoint.

A process and apparatus for the transfer out of a tight enclosure of a fluid solution contained in a polluted container (R1). The transfer is accomplished without removing the polluted container from the enclosure and without breaking the seal of the polluted container. After a clean container (R2) is placed in a receptacle (30) normally isolated from the remainder of the enclosure, the solution is transferred into the clean container (R2) vacuum by a needle. Transfer of the clean container out of the enclosure takes place pneumatically following rotation of a casing containing the receptacle.

A needle valve comprises a valve body including a conduit portion through which a flow passage is formed and a bonnet portion which screws into a cylindrical well formed in one side of the conduit portion to intersect the flow passage and form a valve chamber within the valve body. The bonnet portion is bored through to support a valve stem upon which is mounted a frusto-conical member, the valve stem and the bore through the bonnet portion being threaded for movement of the frusto-conical member transversly across the flow passage via turning the valve stem. A tubular liner, formed of a flexible material, extends around the periphery of the valve chamber and is split into two semi-cylindrical sections which receive the frusto-conical member and are spread thereby against portions of the valve chamber wall pierced by the flow passage as the frusto-conical member is seated in the liner. Tabs are formed on the bottoms of the liner to extend into a slot formed in the bottom of the valve chamber to prevent rotation of the liner without interfering with the spreading of the liner to seal the valve against flow through the flow passage.

To minimize the time for filling large numbers of bottles with liquid such as milk which is apt to foam, each bottle is initially filled by gravity flow to somewhat less than its full content, and then by vacuum assisted gravity flow to its precise full content. A machine for automatically performing such two stage filling method is provided with a continuous bottle conveying system including a slowly rotating fluid dispensing and bottle conveying turret for the gravity filling stage and with a somewhat faster rotating fluid dispensing and bottle conveying turret of smaller diameter for the vacuum assisted filling stage.

An apparatus for filling a container with a liquid wherein a reservoir or tank is provided with a nozzle having a vent tube extending therethrough. The nozzle and vent tube are closed when in an inoperative state with the vent tube being opened prior to the opening of the nozzle upon actuation of a valve member. The reservoir or tank is subjected to a vacuum which is communicated to the container by way of said vent tube.

This invention is a dripless vacuum nozzle for use in an apparatus for vacuum packaging articles in flexible pouches or bags. The neck of a filled bag is placed around the barrel of the nozzle, and downward movement of the barrel clamps the bag neck between the barrel and a plunger located in and below the opening to the barrel. The bag remains in this clamped position as it is evacuated completely afterwhich it is sealed and severed from the clamp. A pivotally operated ball valve, drip collection cup, and ball check valve prevent any moisture from dripping into the package while it is being evacuated.
摘要:
A rotary container filling machine of the constant level type and which includes a series of radially arranged filling nozzles mounted above a supporting table for the containers which are to be filled for vertical slide movement relatively between raised, inactive positions to the containers and lowered, active or filling positions. The filling machine is adapted for vacuum, gravity or combined vacuum-gravity operation as desired and two distinct, readily interchangeable types of filling nozzles are provided the machine for the purpose of permitting the conversion from one filling mode to another. For this purpose, also, the filler machine is provided with a supply tank for the liquid which is to be introduced into the containers and which is elevationally adjustable to the filler table between a raised position thereto for gravity and combined vacuum-gravity filling and a lowered position thereto for vacuum filling.
摘要:
A rotary acting filler machine for containers such as bottles includes a series of vertically reciprocable filling nozzles adapted to be moved under the control of cam means between raised, inoperative positions to a container with the lower end or tip of the nozzle above the upper end thereof and lowered, operative positions thereto with the tip of the nozzle projecting axially within the container. The upper limit of movement of the nozzles in the filler is controlled by a main plate-type cam which is vertically adjustable in the filler whereby to permit containers of varying overall heights to be accommodated for filling action in the filler without obstruction from the nozzles at the same time while permitting the nozzles to be brought rapidly into filling positions to the containers to attain maximum production output in the filler for any particular type of container. The axial penetration of the nozzles into the containers is controlled by a secondary cam means in the form of a ring which is also vertically adjustable in the filler so as to permit the axial position of the nozzles in the containers being filled in any particular operating run of the filler to be regulated in a manner as will provide a rapid, accurate filling of such containers.

An apparatus for filling a container with a liquid wherein a reservoir or tank is provided with a nozzle having a vent tube extending therethrough. The nozzle is provided with a bellowslike member that coacts with a valve member on the vent tube for sealing the liquid contained within the reservoir. The reservoir is subjected to a vacuum which is communicated to the containers by way of said vent tube.

An automatic-filling valve unit has a nozzle disposable within the neck of a container and a flow control valve is located on the lower end of said nozzle for quick shutoff. The valve is opened by air pressure and closed by a spring. Vacuum is drawn through the lower end of the nozzle constantly while filling of a container progresses and is interconnected to a control valve for the air pressure which operates the flow control valve, whereby when liquid rising in the container reaches the suction inlet on the nozzle, the control valve is actuated to release the air pressure instantly and permit the spring to close the flow control valve.
