Claims
- 1. The method of distributing coal charged into a coke oven from a charging car on an upper level of the coke oven, said oven including spaced oven walls and a coke side door removably mounted at one end of said oven and a pusher side door removably mounted at an opposite end of said oven, said pusher side door includes a leveller bar door aligned with the coal line of the oven, and a leveller bar adapted for distributing the coal is movably disposed on an associated pusher machine adjacent the pusher side door, comprising the steps of:
- (a) supplying said charging car with a predetermined supply of coal;
- (b) charging a pre-determined portion of said supply into said oven for thereby partially charging said oven;
- (c) opening said leveller bar door;
- (d) positioning said leveller bar in said oven generally a pre-determined distance from said pusher side door;
- (e) commencing charging the coal remaining in said charging car into said oven;
- (f) moving said leveller bar to generally said coke side door;
- (g) repeatedly cycling said leveller bar between said coke side door and generally midway of said oven while said charging continues and thereby distributing said coal in said oven;
- (h) moving said leveller bar a pre-determined number of strokes between said pusher side door and generally said coke side door for thereby levelling said coal along generally said coal line;
- (i) withdrawing said leveller bar; and,
- (j) closing said leveller bar door.
- 2. The method as defined in claim 1, including the further step:
- (a) moving said leveller bar to generally said coke side door after the coal has been emptied from said charging car.
- 3. The method as defined in claim 1, including the further step:
- (a) moving said pusher machine to the next oven to be charged after closing of said leveller bar door.
- 4. The method as defined in claim 3, including the further steps of:
- (a) aligning said leveller bar with said leveller bar door; and,
- (b) signaling to said pusher machine upon completion of charging of said pre-determined portion.
- 5. The method as defined in claim 1, including the further step of:
- (a) signaling to said pusher machine upon completion of charging of said pre-determined portion.
- 6. The method as defined in claim 1, including the further steps of:
- (a) stage charging said pre-determined portion; and,
- (b) stage charging said remaining supply.
- 7. A control system for the movable leveller bar of a coke oven pusher machine, comprising:
- (a) means for moving said pusher machine;
- (b) drive means operatively associated with said leveller bar for reciprocally moving said leveller bar between a retracted position associated with said pusher machine and an extended oven position;
- (c) control means associated with said drive means and adapted for selecting any one of off, cycle and finish leveller bar movement configurations;
- (d) manual control means operatively cooperating with said drive means and associated with said control means when in said off configuration and adapted for selectively moving said leveller bar;
- (e) cycle control means operatively cooperating with said drive means and associated with said control means when in said cycle configuration and adapted for providing continuous reciprocal movement of said leveller bar between said oven position and a first pre-selected position intermediate said oven and said retracted of positions;
- (f) position sensing means associated with said leveller bar and connected to said cycle control means for monitoring said leveller bar movement and communicating said leveller bar movement to said cycle control means for thereby permitting control of said leveller bar movement;
- (g) finish control means operatively cooperating with said drive means and associated with said control means when in said finish configuration and adapted for providing a pre-determined movement configuration of said leveller bar between said oven and retracted positions;
- (h) said position sensing means communicating with said finish control means for thereby permitting control of said leveller bar movement; and,
- (i) interlock means associated with said means and said position sensing means for preventing movement of said pusher machine when said leveller bar is moved from said retracted position.
- 8. The system as defined in claim 7, wherein:
- (a) said control means includes switch means.
- 9. The system as defined in claim 7, wherein:
- (a) said manual control means includes a manually operated controller having a pivotable handle whereby pivoting of said handle causes associated movement of said leveller bar by said drive means.
- 10. The system as defined in claim 7, wherein:
- (a) said cycle control means includes forward direction relay means associated with said drive means and rearward direction relay means associated with said drive means;
- (b) said forward and rearward direction relay means cooperate with said position sensing means; and,
- (c) said forward and rearward direction relay means are cooperatively associated for causing said leveller bar to be reciprocally moved between said oven and intermediate positions.
- 11. The system as defined in claim 7, wherein:
- (a) said finish control means includes forward finish relay means and rearward finish relay means operatively associated with said drive means and said position sensing means; and,
- (b) said forward finish relay means and said rearward finish relay means are operatively associated for reciprocally moving said leveller bar between said oven position and a second intermediate position intermediate said first intermediate and retracted positions.
- 12. The system as defined in claim 11, wherein:
- (a) said finish control means includes adjustable switch means operatively associated with said leveller bar and said forward finish and rearward finish relay means for causing said leveller bar to move a pre-determined number of times between said oven and said second intermediate position.
- 13. The system as defined in claim 12, wherein:
- (a) said adjustable switch means includes a stepper switch.
- 14. The system as defined in claim 7, wherein:
- (a) said position sensing means includes a rotary switch means having a plurality of contacts, each of said contacts associated with a pre-determined movement of said leveller bar.
- 15. The system as defined in claim 7, wherein:
- (a) said interlock means includes at least a first limit switch adapted for sensing movement of said leveller bar from said retracted position.
