missing pin

[pat]

This happens about three thimes per game. It sounds so simple but..... well you know. This only happens when I am looking at something else.

What happens is when a new rack is spotted there is no 6 pin in the cup. When I look at the bin, sometimes, there is the 6 pin that was supposed to be in the cup. I have checked the shuttle, everything on the shuttle.

I have just worked on the distributor. it seems to be working well and we have not had a stacking problem on that lane.

Any help! Since the desk person quit I am also doing that and do not have time to monitor problems like this. If I had time to watch this I am sure there is something obvious that I am missing.

Thanks guys.

Re: missing pin

Pat,

I have 3 suggestions for you…

1) With the dist. in the #6 position & the machine running, push the carriage all the way back & let it go. If the force of the carriage returning to full extendtion causes it to index, lengthen the trip cable (or rod, whichever you have) 1 turn at a time until it won't index when it extends. (This “auto-indexing” will sometimes occur at the #5 as well)

2) If there isn't one there already, install a bin strap at the 6. (Use the Tuffy ones that Stahl's sells. More $$ but they'll never break) Sometimes they look OK but are just narrow enough to cause an intermittent problem. I have bin straps on 4-5-6-7-8-9-10. It's cut down on a lot of problems, including shuttle tube breakage.

3) If the previous 2 suggestions don't cure the problem, shorten the shuttle rod ½ turn at a time until the problem disappears.

Re: missing pin

Got a 21st century fix for the shuttle idea. Vantage makes a "Twin Pin Guide" its a one piece urethane, includes the two pin holders and a bin strap! Never break! Actually I think they make a shuttle stronger, I have one built up at my center, Im missing a few, have to order some more but wow is it stronger! Only thing is you cannot install one on the 9 so AMF makes the urethane single pin holders.

As for your dizzy problem souns like what dutch said. Sounds like your flag is sinking below the stop blade on the clutch plate when it retracts to dump the six and 10 in. I would also check your eccentric rollers too!

Good Luck [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Re: missing pin

Auto indexing is usually caused from the misadjustment or misunderstanding of the trip rod assembly.

The newest style assy. has a nylon washer and a pivit bushing. If you notice, the bushing is alittle longer than the trip rod support casting.

Firstly make sure your roll pin isn't broken which connects the rod and support casting. If it breaks, drill it out and put a bigger roll pin in there.

When you assemble it onto the Dist. you want the the nylon washer to fit against the bushing, then a steel fendeer washer and locking nut.

When you tighten this assy. you want to do it slowly; once the nylon washer starts to mushroom over the pivit bushing and touches the casting stop tightening.

Now check the trip rod for freeplay. If you have freeplay tighten alittle more. You want this assy. tight enough to allow a smooth index and no FREEPLAY. It must be ridgid enough to stop the clutch plate firmly as it spins around.

If you have freeplay and misadjusted carriage rollers, your clutch plate will slip under the stop blade and skip a bin position.

Make sure your stop blade is centered on your clutch plate. If not refer to Dutch's post #1.

Re: missing pin

Deadwood,

No offence but those twin pin guides cause many jams. When shuttling the pin on top (second ball) catches on the thick bottom of the web. There is not enough clearance for the pin to get by like with a bin strap only. Great idea except it doesnt work.

If the carriage is hitting too hard....just stretch the linear spring. Check the stop blade whrn the dist. indexes from 5 to 6. Possibly adjust the trip arm rod longer.

Re: missing pin

I don't know why everybody is suggesting distributer adjustments?

Re: missing pin

i too would assume first off that distributor is skipping 6 pin. then play with shuttles. or could it simply be cup is squeezed and bringing the 6 pin back up with it

Re: missing pin

Pat,
In addition to the suggestions made already, I would also check to see if the carriage tube is bent. I've notice on some of my machines with the OEM aluminum tubes, the tubes have developed a curve or bend to them. As the distributor retracts, the position of the stop blade changes, thus causing indexing (or lack of) problems. I have starting changing out ours to the Tuffy (Stahls) black ones. They are studly! About double the metal, and made of I think, steel. They will not bend. Good luck.

Deadwood,

I also have to respectively disagree with you regarding the Vantage pin holders. I've found with mine, the pin will not lay flat in the bin. The butt gets caught on the bin strap, then the head sticks up. I have changed mine to the Tuffy (Stahls) metal pin holders with the industrial strength bin straps that Dutch is refering to. This has cut down on jams.

Re: missing pin

I always thought if you kept the machine original and clean that it would run. Why use all the fancy gimmicks from some other company that just wants your money, when all it takes is original equipment and good work ethics to keep your equipment up and running correctly.

Re: missing pin

Got it guys! It was an adjustment on the eccectric rollers! One was out and the trip rod would intermittntly rub on the support guide due to the extra scack.

I hate Intermittent problems If something would just break it would be a lot easier to fix. Problems on these machines are usually not that bad to fix. Often is the time you look for a lot more time to find a problem than you do to fix the problem.

Re: missing pin

The only way to get the Vantage twin pin guide to work is take a knife and round off the material on the strap area at a steep angle so the pins lay flat. Otherwise they cause pinjams.

If it has Tits, Tires or says AMF, chances are your going to have problems with it.
