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

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

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

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

5#5 "Spindle Move To Pocket"Pocket output 15output"    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#6 "Spindle At Cut"Cut 20Input"      This only high when the spindle is at cutting height (This is the feedback for 3 turning on)

7#7 "Spindle At Pocket"Pocket 23Input"     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#8 "Spindle At Clearance"Clearance 19Input"      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#9 "Carousel Extended"Extended 25Input"      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#10 "Carousel Retracted"Retracted 26Input"      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.

 

Drill Bank Config

Since Komo's have their drill banks fixed directly to the back plate and put the spindle on air we have to handle the drill bank differently.

 

We used a PMC and inverted the logic a bit.
