AngryChris Posted July 23, 2014 Share Posted July 23, 2014 I really wanted to start a thread like we did with the refrigeration troubleshooting (which really should be a sticky if it isn't already). I have several machines with column issues. Two of these machines only sell 3-5 kinds of products so I usually just move a selection to an unused column when a column jams up. One machine is a SINGLEPRICE 501T. The machine would vend 1-2-0 or 2-1-0 (you get the idea) out of a wide column. On the same machine (SP 501T), customers complained that they got Mountain Dew whenever they put enough money in to buy something. As soon as you put money in, Mt. Dew vended on its own. I solved this problem by disconnecting the switch. Out of the two metal "tabs" on the switch (sound right?), One was bent and was not allowing the other to catch the cam properly. I figured it was preventing the brake from engaging and causing the selection to home whenever enough credit was inserted in the machine. I really don't know what every part is nor do I know for sure if it was the switch, but disconnecting it solved my problem. I moved this selection to a narrow column. On a multiprice 501T, the machine occasionally dry vends/double vends (uncommon). I figure it is a gummed up motor. On a Single Price 368, one of my narrow selections keeps jamming. By jamming, I mean that the selection closest to the sold-out paddle will be tilted, causing the rotor to get jammed up. At first, I though that the paddle somehow had enough spring-pressure to tip the cans. When I pressed my fingers against the other paddles, they seemed identical. Because of this, I was wondering if maybe my shims are the culprit (I don't see how) or if my rotor was slightly warped (It didn't look that way). I don't know how this could happen because it seems like the only way that ONE can out of two could get tilted/jammed is if there was some kind of debris on the rotor.

AZVendor Posted July 23, 2014 Share Posted July 23, 2014 So many problems...... Single price 501T wide column: Make sure you have the proper shims on each side of the column (compare to a working column). Make sure none of the anti-theft triangles are bent - if they are, remove them. Check for a gummed up brake or motor switch not stopping the motor. Lastly it could be a bad gearbox in the motor. If it's the same can position that drops when it shouldn't then it's a physical problem - shim, anti-theft device, bent column wall, bent oscillator bar. Same machine pre-selects Mtn Dew: Stuck or bad selection switch, sticking push button, gummed up motor brake, magnetized motor not releasing the brake, gummed up motor switch. Multiprice 501T: Gummed up motor switch or motor brake or magnetized motor. Single price 368: When the front can in a narrow column jams as you described it is because the s/o paddle got stuck inside the bottom of the can. This is common with Pepsi cans so I'll wager it's a Pepsi flavor. The shape of the paddle is at fault. Very few DN machines had s/o paddles with a curve to the bottom edge that avoids this issue so the solution is to turn the cans around in that column ONLY so the paddle won't get stuck. Now that this has happened though, you need to inspect the rotor for straightness because it might be slightly twisted now which can cause more jams.

rmorris1953 Posted July 23, 2014 Share Posted July 23, 2014 AZ is correct... Back in the day the bottom of the cans were changed. When the motor runs it will lift the stack just enough to vend. It will push the paddle into bottom of the can. It only happens when there isn't enough cans to push it out. Like the last 10 or so in the column. This is on all pre 90 series D/N vendors. Not shimless stacks... Two ways of fixing Unplug the stack and insert a long screw driver in the opening just below the sold out switch (has to be done with pop out) push the screw driver in just far enough to feel the paddle with your other hand push down a couple of inches on the paddle to bend it straight down. Adjust your back spacer. Test vend and if the sold out light comes on but don't vend you will have to take sold out cover off and bend the tab up on the paddle. Second and easiest load the tops out. Bottom out is used only to see the expiration date. Cans should drop front first and then the back. If not the rotor is bent and will have to be replaced. When the rotor turns there should not be any sounds like metal scraping or groaning while it turns. If you don't have a rotor you can put it on single depth by moving the back spacer and putting the cam in the correct notch Link to comment Share on other sites More sharing options...
AngryChris Posted July 23, 2014 Author Share Posted July 23, 2014 Actually, it was pepsi that was getting jammed on the 368. The sprite didn't seem to jam when I swapped selections. Link to comment Share on other sites More sharing options...
AZVendor Posted July 23, 2014 Share Posted July 23, 2014 Pepsi products are the ones that this happens to so just turn the cans around and they should vend fine. Link to comment Share on other sites More sharing options...
