  • Crossconveyer pins slipping

    Recently installed new crossconveyer belts on all of our pinsetters. Old belts still worked but in rough shape and missing many cogs, so decided to replace all of them.

    We are now having a problem with the pins getting up the cross conveyer (they slip as if coated with oil even though are clean & dry) and causing a lot of jams in the turn-around pan. The new belts do not have enough power to pull the pin across the pin-gate at the top of the cross-conveyer.

    I ask our distributor about it, and they said they have had several complaints from other customers/bowling centers regarding new belt problems. The distributor contacted Brunswick but they deny any problem with their belts. Even though they do not make them, they are made by some supplier. These belts are different from the previous belt, they appear to be narrower and not quite as tall as the old belts.

    Has anyone else had this problem with new belts and what did you do to correct it?...Thanks

    Re: Crossconveyer pins slipping

    I had to install a spring by the pin gate going over the cross conveyor. Had way to many gates locking because the pin couldn't get over the unlocked gate, go backwards and lock it. [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]
    I know there was a thread on this subject a few months back.

      Re: Crossconveyer pins slipping

      We have had the same problem with our belts that we have bought in the past year. We've been getting belts from Done Rite Bowling Supply and have had the same problem. They try to say that no one else is having the problem, but I can't believe we're the only one. Our belts are also narrower but I haven't checked the heighth. No matter what machine we put them on we have a problem with them for several weeks. Some of them will not run right at all. If anyone has any experience with this I would appreciate knowing what you have come up with. Sorry but I don"t buy having to put a spring on the C.C. It didn't come that way and it was running alright until we got these junk belts.

        Re: Crossconveyer pins slipping

        I had the same problem a few months back, and one of my guys did the spring across the cross conv too, and it worked well, but I didn't like the way it looked. So I simply turned the belts around so the pins ran a;png the high side of the belt instead of the beveled side, and it worked fine. Brunswick has to get 10,000 complaints before they admit having a problem with something. Gates used to make their belts, I don't know who does now.

          Sorry about the mis-spelling on my last post. I meant to say that the pins will ride along the high side of the belts instead of the beveled side. OOPPS.

            I have found that the pin slip kits work well with the black brunswick belts.I will try to post a pic.The kits are avalible from Jeff Learner in Ca.

                  For a quick fix, a bungie cord hooked over the top of the x conveyor over the pin gate will work. I work in a BRC center in Mn. and we do this on problem machines. However, this will not pass a 51.20 inspection-LOL.
                  Yeah but, We've always done it that way.

                    You replaced belts that work with belts that don't work? Easiest solution is put the old ones back on. I even turn old ones around and run them backwards, high side toward center of cr conv when they get badly worn. We replace them when they don't move the pins, 1 machine at a time. We got a little slipping problem on 5 or 6 machines out of 24 when we put in new pins, mostly showed up as fail to index on 1,7,10. A little belt dressing made them work. I know running belts backwards will be a problem if you work in a chain and have a guy with a clipboard looking over your shoulder. I only have a proprietor who wants happy customers.

                      Had this same problem last spring and noticed the pins rode on the point of the belt where it changes angles to the bevel (like the bevel angle is incorrect) I used a bench grinder to just relieve the point of the angle a little and I always use a soft wire brush on the bench grinder to buff the traction part of cross conveyor belts before installing. They seem to have something on them when new that decreases friction. Works for me.

                        Peanut, stop putting your pictures on this site, it makes me sick everytime I look at them, LOL. Damn it.
                        We used to have problems with different belts but since we slowed the pinsetters down it doesn't really matter what we change on them they just run great,(another great solution from Peanut).

                            I had the same problem with alot of the new black belts. What I found was a problem with the molding process of the belts. There is a small ridge on the belt at the base of the slanted area of the belt. This means that the pins are being carried up by about 1/16" of rubber instead of the whole 1/2".

                            Look closely at your belts and see if they are like that.

                            I got creative instead of fighting with brunswick. I mounted a pulley in the vise, and a power lift motor to the bench. I installed a pulley on the motor suitable for the belt. I then ran the belt around the pullies and turned on the motor. Using a course file, I cut the bump off the belt first running it 1 way, and then the other following up with 80 grit emery cloth. I re installed the belts on the CCs and havn't had a problem with them sense.

                            Good luck with whatever you decide to do.

                              I know that this is a belt issue....but I wanted to make a comment on slipping pins. We stayed with tried and true belts...but still had slippage from time to time. I saw something here on this forum site and convinced the owners of the house I work at to buy them. We call them diapers now. HA. But they are turn pan cloths that you mount over the turn pan. There is a hole for the cam as well. We take them off twice a week and wash them. Knock on wood we havent had a slipping problem since. Whoever posted it a while back also posted a picture of them. We ordered them from our regular supplier....Ace Mitchell in our case.

                              I know your problem is with those belts.....but these diapers/covers have helped us alot.

                              Wouldnt run without them now.
