Toner agitation system including a cam driven reciprocating toner agitator
A toner agitation system according to one example embodiment includes a toner agitator movable in a reciprocating manner. A cam follower is operatively connected to the toner agitator. A rotatable cam has a cam surface that contacts the cam follower. A biasing member biases the cam follower into contact with the cam surface. Contact between the cam surface and the cam follower during rotation of the cam causes the toner agitator to move in the reciprocating manner.
1. A toner agitation system, comprising:
a toner agitator movable in a reciprocating manner;
a cam follower operatively connected to the toner agitator;
a rotatable cam having a cam surface that contacts the cam follower; and
a biasing member that biases the cam follower into contact with the cam surface,
wherein contact between the cam surface and the cam follower during rotation of the cam causes the toner agitator to move in the reciprocating manner,
wherein the cam follower is formed integrally with the toner agitator.
2. The toner agitation system of claim 1 , wherein the biasing member biases the cam follower into constant contact with the cam surface throughout an entire rotational path of the cam.
3. The toner agitation system of claim 1 , wherein the biasing member is an extension spring that pulls the cam follower into contact with the cam surface.
4. The toner agitation system of claim 1 , wherein the toner agitator is movable in the reciprocating manner along a lengthwise direction of the toner agitator.
5. The toner agitation system of claim 1 , wherein the toner agitator is translatable linearly in the reciprocating manner.
6. The toner agitation system of claim 1 , wherein the toner agitator is translatable linearly in the reciprocating manner along a lengthwise direction of the toner agitator.
7. A toner container, comprising:
a housing having a reservoir for storing toner;
a toner agitator movable in a reciprocating manner within the reservoir;
a cam follower operatively connected to the toner agitator;
a rotatable cam having a cam surface that contacts the cam follower; and
a biasing member that biases the cam follower into contact with the cam surface,
wherein contact between the cam surface and the cam follower during rotation of the cam causes the toner agitator to move in the reciprocating manner,
wherein the cam follower is formed integrally with the toner agitator.
8. The toner container of claim 7 , wherein the biasing member biases the cam follower into constant contact with the cam surface throughout an entire rotational path of the cam.
9. The toner container of claim 7 , wherein the biasing member is an extension spring that pulls the cam follower into contact with the cam surface.
10. The toner container of claim 7 , wherein the toner agitator is movable in the reciprocating manner along a lengthwise direction of the toner agitator.
11. The toner container of claim 7 , wherein the toner agitator is translatable linearly in the reciprocating manner.
12. The toner container of claim 7 , wherein the toner agitator is translatable linearly in the reciprocating manner along a lengthwise direction of the toner agitator.
13. A container for storing waste toner in an electrophotographic image forming device, comprising:
a housing having a reservoir for storing toner, at least one toner inlet permitting toner to enter the reservoir;
a toner agitator movable in a reciprocating manner within the reservoir, the toner agitator includes a cam follower;
a rotatable cam having a cam surface that contacts the cam follower; and
a biasing member that biases the cam follower into constant contact with the cam surface throughout an entire rotational path of the cam,
wherein contact between the cam surface and the cam follower during rotation of the cam causes the toner agitator to move back and forth in the reciprocating manner against a direction of bias of the biasing member on the cam follower and in the direction of bias of the biasing member on the cam follower,
wherein the cam follower is formed integrally with the toner agitator.
14. The container for storing waste toner of claim 13 , wherein the biasing member is an extension spring that pulls the cam follower into contact with the cam surface.
15. The container for storing waste toner of claim 13 , wherein the toner agitator is movable in the reciprocating manner along a lengthwise direction of the toner agitator.
16. The container for storing waste toner of claim 13 , wherein the toner agitator is translatable linearly in the reciprocating manner.
17. The container for storing waste toner of claim 13 , wherein the toner agitator is translatable linearly in the reciprocating manner along a lengthwise direction of the toner agitator.
18. A toner container, comprising:
a housing having a reservoir for storing toner;
a toner agitator movable in a reciprocating manner within the reservoir;
a cam follower operatively connected to the toner agitator;
a rotatable cam having a cam surface that contacts the cam follower; and
a biasing member that biases the cam follower into contact with the cam surface,
wherein contact between the cam surface and the cam follower during rotation of the cam causes the toner agitator to move in the reciprocating manner,
wherein the biasing member is an extension spring that pulls the cam follower into contact with the cam surface.
