sweep drifting

[keg-R]

we have a lane where the sweep is drifting it will start a cycle and go from zero position to guard position and drift when its supposed to stop we canged contactors in the chasis checked motor checked wireing and checked sweep its self and it still does this we cant seem to fuigure it out any halp is apreciated [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]

thanks again,

Re: sweep drifting

1. Check SB switch with the gauge.
2. Adjust cam position on the drive shaft.

If it still coasts.....swap out the whole gearbox and motor assembly.....it is possible that there is not enough mechanical resistance.

Is the finger spring installed between the motor and gearbox?

Do you have ss switches on the motor head?

Are you using the original switches?

Re: sweep drifting

i dont know what the finger spring is ans no ss switches and the original moter switches are what we are using

your up late

thanks keith

Re: sweep drifting

The finger spring sits on top of the bearing on the rotor shaft.

It provides mechanical resistance so the motor will not coast.

The washer is the same size as the bearing.......had 3 risers on it......also called a Bellville washer.

Possibly you have a bad capicitor too.

Re: sweep drifting

If it's only coasting when it should stop at 66*, I'm going with ring gear/helical gears. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Re: sweep drifting

Possibly a bad pin or socket in the C-1 Cable?

I just had a machine doing that and it was a bad capacitor. Opened up the wireway and it was leaking all over. What a mess.

Re: sweep drifting

we tried the contactor and checked all the wires in the c-1 and c-2 plugs

jerry i was wondering are the finger springs part no 070.001.707 if so we only have 1 hooked up and the books show 3 should i put 1 or 2 more to help sweep with this problem if this is not the part no. please give the part no. so im sure of whitch part your talking about

thanks,

Re: sweep drifting

im gonna guess natinal motors,

dont try to make these perfect. put the seimens relays in your chassis. new carbon brushes in your brakes, adjust the SB lever in to stop the sweep before 66, and adjust the SC lever out to trigger later. this will buy you about an extra foot of drift before having to worry about interlocking.

Re: sweep drifting

Stopping late under power (good solid stop), it's low-voltage related, such as switches, wires or terminals from switches to TS terminal strips, C2A.

Coasting slowly to a stop is high-voltage related, such as capacitor, motor plug/receptacle, contactor points, C1, start switch (any type...start winding staying on with the run winding), any wires or terminals related to the afore mentioned devices, or the stator itself (start winding shorted to run winding internally).

Plug the table motor cord into the sweep motor and use TA1 to run the sweep. If it still coasts, the problem is in the motor (switches, mech, or receptacle wires). If not, it's in the machine (contacts, capacitor, wiring, C1).

Good luck!!

Re: sweep drifting

it is slowly drifting to a stop the motor is fine the gear box is fine and the springs on the cam fingers are fine i will cheack the things mentioned with the high voltage thanks ill keep you posted if it worked

Re: sweep drifting

CAPACITOR....REPLACE BOTH MARKED CSM IN CHANNEL.....CHECK PLUG MACH SIDE....ALSO MAKE SURE YOU USE GOOD MOTOR HEAD FROM ANOTHER MACH OR CHASSI FROM ANOTHER MACH THAT YOU KNOW IS GOOD................BPM

Re: sweep drifting

Keith: I have yet to see what type of motors you have. That would help somewhat in helping you troubleshoot your problem.
