Abstract:
A filling apparatus for metal containers has a rotatable bowl carrying filling syrup or other fluid with a plurality of filling valves arranged on the bowl bottom around its periphery to fill empty containers moved into traveling engagement with each valve. A control cam manipulates each valve in a repeating sequence through close, vacuum, fill and vent positions. A switching cam follower tracking the control cam and a cooperating switch activate the valving sequence if a can is present at a particular filling valve and de-activate the sequence if a can is not present. A pneumatic cylinder actuated by series connected proximity sensors for metal objects, such as cans, manipulates the cooperating switch to direct the switching cam follower for each filler valve into one control cam tracking mode if an empty can is in place below the filler valve or into a second valve closing mode if a can is not present. One sensor detects filler valve position and the other sensor detects presence of a can by a change in the inductance of the sensor produced electric field. Concurrence of sensor outputs manipulates the cooperating switch.
Abstract:
A vacuum filler is described which has an improved filling head particularly adapted for vacuum filling steel cans containing more-or-less compressible and tacky food products, such as tuna fish or salmon, with filling liquids of low viscosity, such as vegetable oil or water.
Abstract:
Apparatus and methods are described for pitting fruit of the drupe type in a cyclical manner in a processing operation involving a series of processing steps in which fruit having a sound pit is torque pitted and fruit having a split pit is spoon pitted. In the apparatus and method the presence or absence of a fruit to be supplied to the pitting station from a preceding station is sensed and the cyclical operation of the process and the apparatus with the cyclical sequence of steps and machine operations is varied depending upon whether a fruit is presented to the pitting station during a cycle of operation or not, and if a fruit so presented has a sound or split pit. When a fruit having a split pit is presented, a coring spoon spaced from the pit gripping portion of fruit bisecting blades is moved into position by moving the blades and coring spoon through the fruit and between the halves of the split pits for cutting a core including the split pit from the fruit. If no fruit is presented during a cycle of operation the fruit gripping structure at the pitting station is disabled.
