Abstract
A bag closing apparatus including a frame structure, a cinching assembly and an actuator assembly. The cinching assembly includes at least three pivot arms, each pivot arm including an arcuate portion and pivotably connected to the frame structure. The pivot arms are located relative to each to define a confined closure area. The actuator assembly includes a plurality of actuators for moving the pivot arms between spread positions and closed positions wherein the closure area has a smaller area.
Claims7
A bag closing apparatus comprising:
- a frame structure;
- at least two pivot arms, each pivot arm having first and second ends and an arcuate portion therebetween, pivotably connected to the frame structure adjacent one end thereof and located relative to each other such that each pivot arm crosses at least one other pivot arms to define a confined closure area;
- and
- actuation means for moving the pivot arms along an arcuate path between spread positions wherein the closure area has a predetermined area and closed positions wherein the closure area has a smaller area.
A bag closing apparatus comprising:
- a frame structure;
- at least three arms, each arm having first and second ends and an arcuate portion therebetween, connected to the frame structure and located relative to each other such that each arm crosses at least two other arms to define a confined closure area;
- and
- actuators for moving the arms between spread positions wherein the closure area has a predetermined area and closed positions wherein the closure area has a smaller area.
A pinch valve, for regulating a material flow, comprising:
- a frame structure;
- at least three pivot arms, each pivot arm having first and second ends and an arcuate portion therebetween, pivotably connected to the frame structure adjacent one end thereof and located relative to each other such that each pivot arm crosses at least two other pivot arms to define a confined closure area;
- actuation means for moving the pivot arms along an arcuate path between spread positions wherein the closure area has a predetermined area and closed positions wherein the closure area has a smaller area;
- and
- an elastic bladder having a first end for receiving material and a second end for discharging material extending through the confined closure area.
