An improved filling valve and liquid filling machine comprising such valve are herein disclosed. The filling valve comprises a housing having a base, a cap and a sidewall extending between the base and the cap thereby defining a chamber. The base has a ramp which slopes from a bottom surface of the base toward the cap. An outlet tube extends from said housing and has an inlet opening in fluid communication with the chamber. An inlet port extends through the sidewall to allow liquid product to enter the chamber. A plunger guide having an opening is provided on the cap with the opening extending through the cap. A plunger is slidably received in the outlet tube and the opening in the plunger guide. The plunger is movable between a position in which the plunger seals the outlet tube thereby closing the valve and a position in which the plunger is withdrawn from the outlet tube thereby unsealing the outlet tube and thereby opening the valve. The filling valve may be utilized on a liquid filling machine to fill containers with liquid product.

A filling amount adjustment device for a liquid-form substance filling machine, the device including first sliding units disposed on a swing arm and connecting links pivotally attached at one ends to connecting pins of first sliding members (of the first sliding units) that slide along the length of the arm. Second sliding units are disposed on both sides of the swing arm, and the other ends of the connecting links are pivotally connected to the connecting pins of second sliding members (of the second sliding units). Connecting rods connected to piston rods are pivotally connected to the connecting pins. When fine adjustment shafts in which male screws are cut are rotated, the second sliding members are moved and positioned; as a result, the first sliding members slide via the connecting links, thus changing the positions of the connecting pins in the direction of length of the arm.

An apparatus dispenses flowable material from a source and includes a dispensing nozzle that reciprocates along an axis. A metering assembly includes a metering cylinder, a metering element reciprocally movable in the interior of the metering cylinder and a switching valve to switch the metering assembly between a metering mode wherein material flows into the metering cylinder and thereby displaces the metering element and a discharge mode. A metering element drive moves the metering element into the metering cylinder during the discharge mode to displace material thereby to dispense material through dispensing nozzle. A lift bracket is mounted for common equidistant movement with the metering element, and the dispensing nozzle is interconnected to the lift bracket for equidistant movement in one direction.

An apparatus for filling a specified amount of liquid comprises a vertical tubular filling nozzle, a damper attached to the lower end of the filling nozzle and pivotally movable upward and downward, a vertical rod supported upwardly and downwardly movably inside the filling nozzle, a connecting member connecting the free end of the damper to the lower end of the vertical rod, a spring biasing the vertical rod upward to hold the damper closed against the gravity on the liquid within the nozzle, and a metering cylinder for feeding the liquid to the nozzle in the specified amount at a time to open the damper against the spring. An annular seat facing downward is formed on the inner surface of the nozzle approximately at the midportion of its height. A liquid channel blocking annular member is mounted on the vertical rod so as to come into contact with the seat simultaneously when or immediately before the damper is closed. The volume of liquid fed from the metering cylinder to the nozzle at a time is greater than the volume of liquid to be accommodated in the nozzle in the portion thereof under the blocking member.
摘要:
This device for rapid and extremely accurate filling of containers includes a duct for bleeding off gas bubbles from a metering device, where prior bubble-eliminating provisions are inadequate due to extreme product viscosity. The device also has relative adjustment between a positive mechanical stop, used to define very precisely the substance volume metered by a biacting piston, and a control switch used to reverse the piston. This adjustability corrects an inaccuracy arising in prior devices due to the necessarily slower speed of the piston with extremely viscous product.
摘要:
A filler head for delivering a preselected volume of product to a container, the head having a charging cylinder and a piston movable in the cylinder to define a product chamber therein. Product is delivered under pressure through a passage to the chamber, the piston being movable under product pressure in a direction enlarging the chamber. Adjustable stop means limit chamber enlarging movement of the piston to determine the preselected volume. A plug entering the passage as the piston approaches the end of its discharge stroke restricts the discharge of product to reduce turbulence. A piston valve is movable between the product passage and an outlet passage, in one position interrupting the delivery of product to the chamber for discharge of product from the chamber through the valve to the outlet, and in another position closing the outlet and permitting delivery of product under pressure to the chamber. The piston valve is removable as a unit from the head, for ease of cleaning.
