All Komo Tool Changers 4/30/2024 And Newer

Dump valve needs to mapped to an enable relay, if it's not on all of this will get very buggy

 

Outputs

1 "Retract carousel  output" 14      Interlocked with #2  (The solenoids are mechanically interlocked, one must turn off before the other will fire)

2 "Extend Carousel output" 13     Interlocked with #1  (The solenoids are mechanically interlocked, one must turn off before the other will fire)

3 "Spindle Move To Cutting Zone" output 18     Interlocked with #4  (The solenoids are mechanically interlocked, one must turn off before the other will fire)

4 "Spindle Move To Tool Changer Zone" output 17     Interlocked with #3  (The solenoids are mechanically interlocked, one must turn off before the other will fire)

5 "Spindle Move To Pocket" output 15    This what makes KOMO's tricky, It fires down when turned on and retracts up when turned off, it is stronger than #4 and can push it out of the way.

 

 

 

 

Inputs

6 "Spindle At Cut" 20      This only high when the spindle is at cutting height (This is the feedback for 3 turning on)

7 "Spindle At Pocket" 23      This only high when the spindle is at Pocket height (This is the feedback for 3 tuning off and 5 and 4 turning on)

8 "Spindle At Clearance" 19      This only high when the spindle is at Clearance height (This is the feedback for 3 and 5 turning off and 4 turning on)

9 "Carousel Extended" 25      This only high when the Carousel is extended to tool change position (This is the feedback for 1 turning off and 2 turning on)

10 "Carousel Retracted" 26      This only high when the Carousel is retracted to clearance position (This is the feedback for 2 turning off and 1 turning on)

 

Here is another Pic showing the air cylinder a bit better.

 

The Steps needed for for a normal tool change are as follows. (this is presuming 6 and 10 are high)

Stage 1, Open Dust hood, 

Stage 2, Prep spindle down to pocket set 5 high wait on no inputs (7 won't go high unless 4 is set to high along with 5)

Stage 3, Raise spindle to pocket  set 3 to low and 4 to high,(5 should still be High from stage 2)  Wait on 7 to go high.

Stage 4, Spin carousel axis to the empty pocket

Stage 5, Extend carousel set 1 to low and 2 to high,  Wait on 9 to go high.

Stage 6, Open Drawbar

Stage 7, Raise spindle to clearance set 5 to low (4 should still be High from stage 3)  Wait on 8 to go high.

Stage 8, Spin carousel axis to the new tool pocket

Stage 9, Lower spindle to pocket  set 5 to high, (4 should still be High from stage 3)  Wait on 7 to go high.

Stage 10, Close Drawbar

Stage 11, Retract carousel set 2 to low and 1 to high,  Wait on 10 to go high.

Stage 12, Lower spindle to Cut set 4 to low and 3 to high,  Wait on 6 to go high.

Stage 13, Lower Dust hood

 

 

 

This is how things are currently mapped at CTP

 

This is what enables stage 2

 

Here is where each function is mapped in the current tool changer options

Dust hood and drawbar are setup as normal.
