Abstract
Mixers for adhesives and sealants that include automatic stroke length adjustment for different sizes and configurations of adhesive and sealant cartridges are disclosed. The mixers include a sensor for detecting when a mixing impeller reaches the top of a cartridge and the bottom of a cartridge, which sends a signal to a main pressure cylinder to reverse direction. The stroke length of the mixer is automatically adjusted without the necessity of manual selection based upon a particular cartridge size.
Claims15
A mixer for adhesives or sealants comprising:
- a cartridge support plate;
- a cartridge holder sleeve mounted on the cartridge support plate structured and arranged to receive at least a portion of an adhesive or sealant cartridge therein;
- a pressure sensitive housing mounted on the cartridge support plate;
- a piston reciprocatingly movable within the pressure sensitive housing defining an upper piston chamber and a lower piston chamber within the pressure sensitive housing;
- an upper biasing element in the upper piston chamber;
- a lower biasing element in the lower piston chamber;
- at least one proximity sensor mounted on the pressure sensitive housing structured and arranged to sense a position of the piston within the pressure sensitive housing;
- a piston rod connected to the piston and extendable from the pressure sensitive housing;
- and
- a main pressure cylinder comprising a reciprocating rod extendable therefrom connected to the piston rod, wherein
- upward movement of the reciprocating rod causes the piston to move toward an upper end wall of the upper piston chamber against force applied to the piston by the upper biasing element, and downward movement of the reciprocating rod causes the piston to move toward a lower end wall of the lower piston chamber against force applied to the piston by the lower biasing element.

An adhesive or sealant mixing assembly comprising:
- a cartridge support plate;
- an adhesive sealant cartridge mounted on the cartridge support plate;
- a pressure sensitive housing connected to the cartridge support plate;
- a piston reciprocatingly movable within the pressure sensitive housing defining an upper piston chamber and a lower piston chamber within the pressure sensitive housing;
- an upper biasing element in the upper piston chamber;
- a lower biasing element in the lower piston chamber;
- at least one proximity sensor mounted on the pressure sensitive housing structured and arranged to sense a position of the piston within the pressure sensitive housing;
- a piston rod connected to the piston and extendable from the pressure sensitive housing;
- a main pressure cylinder comprising a reciprocating rod extendable therefrom connected to the piston rod, wherein upward movement of the reciprocating rod causes the piston to move toward an upper end wall of the upper piston chamber against force applied to the piston by the upper biasing element, and downward movement of the reciprocating rod causes the piston to move toward a lower end wall of the lower piston chamber against force applied to the piston by the lower biasing element, and wherein
- the adhesive or sealant cartridge comprises:
- a lower end with a discharge opening therethrough;
- an upper open end;
- an upper plunger inserted in the cartridge through the upper open end;
- a rotatable dasher rod slidably extendable through the discharge opening;
- a mixing impeller attached to an upper end of the rotatable dasher rod;
- a spindle attachment disk attached to a lower end of the rotatable dasher rod;
- and
- an adhesive or sealant material at least partially filling a mixing volume inside the cartridge between the lower end and the upper plunger.

A pressure sensitive position sensing system for use with an adhesive or sealant cartridge mixer comprising:
- a pressure sensitive housing mounted on a cartridge support plate;
- a piston reciprocatingly movable within the pressure sensitive housing defining an upper piston chamber and a lower piston chamber within the pressure sensitive housing;
- an upper biasing element in the upper piston chamber;
- a lower biasing element in the lower piston chamber;
- at least one proximity sensor mounted on the pressure sensitive housing structured and arranged to sense a position of the piston within the pressure sensitive housing;
- a piston rod connected to the piston and extendable from the pressure sensitive housing;
- and
- a main pressure cylinder comprising a reciprocating rod extendable therefrom connected to the piston rod, wherein
- upward movement of the reciprocating rod causes the piston to move toward an upper end wall of the upper piston chamber against force applied to the piston by the upper biasing element, and downward movement of the reciprocating rod causes the piston to move toward a lower end wall of the lower piston chamber against force applied to the piston by the lower biasing element.
