Abstract
A volume-adjusting mechanism for a filling machine adapted to fill a number of containers with a predetermined amount of a product from a corresponding number of filling units; to enable a volume adjustment while the machine is running, the part of the filling unit normally connected with a relatively fixed part of the filling machine includes a selectively adjustable lost motion volume-adjusting mechanism to permit adjustment of the suction and discharge stroke of the filling unit.
Claims14
A volume-adjusting mechanism for a filling machine operable to fill containers with a predetermined amount of a product and comprising at least one filling unit having at least two parts movable relative to one another and including pump cylinder and piston means, actuating means operatively connected with one of said parts to cause relative movement between said parts and thereby provide a suction and discharge stroke for a respective filling unit, and the other part being adapted to be connected with a relatively fixed part of the filling machine, characterized by volume-adjusting means external of said other part for operatively connecting said other part with said relatively fixed part to enable a change in the volume of the product to be sucked-in and discharged by a respective filling unit by changing the physical location of the effective connection of said other part with respect to the fixed part without change in the volume of the pump cylinder means.
A volume-adjusting mechanism for a filling machine operable to fill containers with a predetermined amount of a product and comprising at least one filling unit having at least two parts movable relative to one another and including pump cylinder and piston means, actuating means operatively connected with one of said parts to cause relative movement between said parts and thereby provide a suction and discharge stroke for a respective filling unit, and the other part being adapted to be connected with a relatively fixed part of the filling machine, characterized by volume-adjusting means operatively connecting said other part with said relatively fixed part to enable a change in the volume of the product to be sucked-in and discharged by a respective filling unit, the volume-adjusting means including adjustable lost-motion means to selectively vary the lost motion between said other part and said relatively fixed part during the suction and discharge stroke of the filling unit.
A volume-adjusting mechanism for a filling machine operable to fill containers with a predetermined amount of a product, comprising at least one filling unit including pump cylinder means and piston means carried by a piston rod and operable to reciprocate within said pump cylinder means, actuating means including an eccentric drive means operatively connected with said piston rod to cause relative movement between said pump cylinder and piston means and thereby provide a suction and discharge stroke for a respective filling unit, and volume-adjusting means external of said pump cylinder means for operatively connecting said pump cylinder means with a relatively fixed part of the filling machine to thereby enable a change in the volume of the product to be sucked-in and discharged by a respective filling unit by changing the physical location of the effective connection of said cylinder means with respect to said fixed part and thereby change the effective stroke of the piston means relative to the cylinder means without changing the stroke of the piston means relative to said filling machine.
