  • turn pans

    Hi guys!Yes it's me wondering about turn pan jams.The 40 laner i am at seems or seemed to get way too many t.p.j. calls so i went through the problem ones,adj.the pin guides,install the missing or broken leafs(duh),check pinwheel for being loose,ck.cross conv.switch,etc.Then went through and lubed the rubber mounts with a good silicone spray to get between frame and mounts,now things are looking better and the turn pans can once again pivot freely,most we're bound up.Ever run into turn pan jam troubles??
    Things are working much better now.

    We been having a increase in our TPJ's lately. Do you know how many leaf springs are supposed to be in place? Wondering if we have fewer than supposed to.

      Hey guys, don't know brand b's very well but amf guys have trouble with pins orienting properly due to the pins picking up oil.

        There is a long spring bolted to guide and a short spring under the long one for support...
        You can also buy or make a support kit to mount under springs to adjust pressure as needed to get pin guide to conform to the shape of pin wheel.
        You also may want to be on the lookout for slipping pins on cross conveyor,this is begining to be more and more of a problem...

        Good Luck

          Just a note. My machines are 40 yrs old. I find some problems are caused by worn tits on the pin wheel(they wear flat) causing pin to hang just a litte. Also, I tried an AMF trick on bruns. mach. I mounted a pit mount on the frame of machine with a piece of 1/16"x6" piece of metal parallel to the pin wheel outer and inter edges of wheel. This makes sure he pins are seated in whell before they reach the turn pan. If you have a good welder, ask him how much it would cost to replace the tits on wheel.

            Re: turn pans

            The major cause of turn pan jams lately is what masternut was talking about, oily CC belts and/or pins not taking the pins away from the pan fast enough.

            Another possibility is that over time, the lip on the front of the turn pan will bend slightly, if the back of your turn pan is dropping down every time a pin goes through, the lip may need to be bent down slightly till that stops.

            The number of spacers between the pin wiper springs and the elevator frame is important, too ... if the wiper is too high (too many spacers or too thick), the belly-first pins may hang their necks on the front edge of the wiper, yet too low causes pins to fall out or jam in the wheel when the buttons get worn.

              we dont have very many problems with turn pan jams, but we do have a problem that only occurs on 2 lanes. Pins seem to want to go up the cross conveyour head first, and of course get stuck under the control box

              Anyone else have this problem often?

                Ok...question.On lane 33 i am getting DOUBLE pins in the pin guide!Its like they are almost on top of each other,the leafs get all bent out of shape (of course),the transfer from pin guide to turn pan IS smooth,i can sit there for 3 hours and it wont have a problem(figures).Its like one pin sits on the guide and another pins jumps on it!Pockets/tits look good.Ideas??

                  I have seen this happen alot esp. in houses that have stamped pin wheels.Whats happening is that the pin is fallin out of pocket as it enters pin guide.I use a bungee cord to hold the pins in pockets.There is also more info posted on an other thead,"modular pin wheels" I believe.You can look under past topic and try to find.

                  Good luck
