Abstract
Abstract A filler volume adjustment control apparatus for a continuous motion liquid container filling machine which can be operated while the machine is in operation. The filling machine has a plurality of product filler stations and each of the stations has a calibration sleeve which can be selectively moved by a power operated control means for increasing and decreasing the volume of each of the filler stations simultaneously, and by small volume increments. The filling machine is provided with a fixed drain trough so that the filling stations can be cleaned simultaneously in place with the use of the automatic filler volume adjustment control apparatus. The volume adjustment control apparatus is push-buttoned controlled. Each filler station is provided with a dual orifice spray diffuser which can be set in one position for light viscosity products and in another position for heavy viscosity products.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
238 words
In combination with a continuous motion liquid container filling machine having a stationary base, a rotatable housing on said base which carries a plurality of product filler stations disposed in an annular arrangement, a liquid supply bowl carried on said rotary housing, each of said filler stations including a filler cylinder having a filler calibration tube, means for admitting a predetermined volume of liquid from said supply bowl to each filler cylinder, a vent tube in each filler cylinder communicating the cylinder with the supply bowl, valve means on the lower end of said filler calibration tube for controlling the discharge of a predEtermined volume of liquid from said filler cylinder, the combination comprising: a. a volume adjustment means mounted in each filler cylinder; b. means for adjusting simultaneously the volume adjustment means in all of the filler cylinders while said rotary housing is rotating; c. said volume adjustment means comprises a calibration sleeve movably mounted in said filler cylinder; d. said means for adjusting said sleeve includes, 1. a power-operated mechanical means, and 2. an electrical control means for controlling the operation of said power-operated mechanical means; and e. said electrical control means includes, 1. a multilobe cam operated by said power-operated mechanical means, and 2. electrical control means for initiating the operation of said mechanical means for a predetermined increment of adjustment of said sleeve for each contact of a lobe by a control limit switch.
Claim 2
Dependent Claim
