Abstract: According to a method for statistical weighing of a product supplied by a plurality of nozzles into containers, an empty container, belonging to a withdrawing group, is withdrawn to define an empty seat in the withdrawing group. The withdrawn empty container is weighed by a scale, to determine a tare weight, and then introduced in an empty seat made in a test group of containers, is a position designed to match with a selected nozzle to be tested. After introducing product into the weighed, empty container, by the selected nozzle, the filled container is withdrawn and weighed by the same scale to determine a gross weight. The exact quantity of product introduced into the filled container is thus determined by difference between the tare and gross weights.
Abstract: A liquid metering-filling apparatus is provided which includes a container transport conveyor intermittently drivable so as to halt containers one by one at a filling station. A filling nozzle is disposed above a path of transport of containers at the filling station. A metering cylinder houses a piston and has an outlet in communication with the filling nozzle. An inlet check valve is provided at an inlet of the metering cylinder. An outlet check valve is provided at any one of the outlet of the metering cylinder and inside of the filling nozzle. The liquid metering-filling apparatus also includes a driver for causing the piston to perform a cycle of stroking movement every time the conveyor is driven by one pitch. A photoelectric sensor is provided at the filling station for detecting any one of the presence and absence of a container of the plurality of containers at the filling station.
Abstract: The invention relates to a metering-out device for taking successive timed doses of liquid from a tank, the device comprising a body for mounting in fixed manner relative to the tank and including a liquid-taking plunger with motion transmission means for driving the plunger with reciprocating motion in the liquid so that in one direction the liquid is metered out and in the opposite direction it is pumped. The invention also provides a metering-out valve including such a metering-out device, and metering-out apparatus including such a metering-out valve.
Abstract: The invention provides a mount for attachment to a link chain conveyor, especially--but not exclusively--for use in an automatic packaging machine. The mount has two pivot points of attachment to prevent unwanted motion caused by centrifugal forces as the mount circles a sprocket wheel. One of the two pivot points is a pair of tracks having wear resistant nylon blocks mounted on them to provide lost motion. Responsive to each lost motion extension, the block rubs the tracks to clean them of debris.
Abstract: A high speed automatic packaging machine is constructed from standardized modules in order to reduce cost and standardize operational and maintenance procedures. The standardized modules include conveyor chains trained over sprocket wheels to form modules which may be ganged to maintain synchronization of operations. Various types of mandrels may be attached to the conveyor chain in order to adapt the machine to load different types of products. The mandrels experience significant centrifugal forces as they go around the path defined by the sprocket wheels. To prevent the mandrels from slapping the conveyor chain when it is traveling at high speed, a leading end of the mandrel is pivotly connected to the chain while a trailing end of the mandrel is captured within a slot which allows the mandrel to go around the sprocket wheel without departing therefrom.

In another embodiment, a temperature sensor is included in the water line and the warm water purging terminates when the temperature falls to a predetermined value.
Abstract: An aerosol can containing a liquid propellant is placed on a can support platform (44). An operator actuated fluid control switch (84) provides pneumatic fluid or compressed air to a pneumatic cylinder (46) which continuously biases the aerosol can upward into engagement with a reservoir outlet (66) of a liquid reservoir (60). A sensing switch (52) senses movement of the can support, hence, the aerosol can. An operator actuated start valve (92) enables compressed air to be supplied cyclically (78a, 78b, 96) to a pump pneumatic cylinder (70). A pump (74) driven by the cylinder cycles a preselected number of times as counted by counter (90) to pump a preselected amount of liquid from the reservoir through the reservoir outlet and into the aerosol can.
Abstract: The invention greatly increases the speed at which a fill step may be completed in an automatic packaging machine. Instead of the usual process where a gate opens and closes for dumping product into each empty box, a plurality of bottomless measuring cups and transfer cups are moved in an aligned sequence with the corresponding boxes. These cups move over planar surfaces which function as the bottoms of the cups and keep the product in place within the cups. At selected locations, the cups pass over interruptions in the surfaces so that the product may fall out of the cup and into an underlying structure.
Abstract: A driving device for a double bellows dispensing unit is disclosed. The device includes a cylinder slidably mounted on a fixed vertical shaft and a plate mounted on the cylinder. The plate is connected with the dispensing unit. A rotary cam and cam follower cooperate to impart oscillating motion to the plate upon upward movement of the cylinder along the shaft. A control valve controls the flow of fluid under pressure to the cylinder for selectively displacing the cylinder in opposite directions. When the cylinder is displaced downwardly by the control valve, the cam and cam follower are disengaged, so that the oscillating motion stops.
Abstract: Liquid from a supply tank B flows into a container C via outer and central annular chambers 14, 8 of filling apparatus A. Communication between the chambers is controlled by a flexible diaphragm 5 selectively urged against an annular seat 15 on a wall 10 separating the chambers in response to air pressure supplied to a chamber 23 on an opposite side of the diaphragm.

Abstract: A gas precharged, liquid filling machine operating with dual rows of containers includes a pair of concentrically disposed inner and outer rows of container receptacles, and an array of pairs of inner and outer gas precharged, filling mechanisms which are disposed directly above the respective rows of container receptacles. The pair of inner and outer filling mechanisms each include a valve which is independently operated, in accordance with the presence or absence of a container, by means of coaxially disposed rotary shafts. Snifter mechanisms for both filling mechanisms are simultaneously operated by a common snifter shaft. Each pair of inner and outer container receptacles, which are modularized, are mounted on a common elevating member in a manner to permit their elastic downward displacement in response to undue stresses applied thereto, thus avoiding the risk that the containers or bottles may be broken.
Abstract: In a container filling apparatus having a plurality of revolving charging cylinders and respective pistons by which a fluid filling material supplied into the cylinders with their pistons at the limit end of their intake strokes is subsequently pushed out of the cylinders and through nozzles to fill respective containers at a filling position, the containers being preparatorily positioned on respective revolving platforms, the piston rod of each of the charging cylinders can be locked at the start of its intake stroke by a respective locking mechanism when the mechanism, as it revolves with the cylinder, contacts and is actuated by a stationary actuating device operated in accordance with a detection signal generated by a monitoring device. When this monitoring device detects the absence of an empty container from its preparatory position on any platform, it generates the detection signal to lock the corresponding piston rod thereby to prevent containerless discharging of the filling material.
Abstract: A valve and control system for filling sequentially presented containers with measured charges of semi-solid food product and the like from a feed hopper is provided in which the food product is charged into a product cylinder from the feed hopper through the valve and then discharged into a container through the valve in timed sequence with the reciprocating strokes of a piston in the product cylinder. Means are provided to monitor the discharge stroke of the piston to reverse the valve from the discharge position to the charge position before the discharge stroke of the piston is completed to cause the food product in the product cylinder to be returned to the feed hopper. This results in a dynamic discharge that precludes tailing of the food product at the valve discharge port and maintains the food product in the feed hopper in a homogenized state. The stroke of the piston is adjustable to predetermine the quantity of food product dispensed.
