Stretch Wrap Machine Troubleshooting Checklist
A stretch wrap machine will save time and money from less film usage and faster, more consistent wraps. When a machine goes down, you notice it and workers wrapping by hand certainly notice it. Below are a few items to check when a stretch wrap machine goes down to hopefully have your problem quickly pinpointed.
Machine will not function, without power
_______ Check incoming power supply for power
_______ Examine machine power cord for damage
_______ Check the machine internal circuit breaker for a flipped switch
_______ Be sure no fuses are blown if accessible
If all of these items are checked, move on to the next section. If incoming power is lower or higher than required, the wrong amperage can cause a machine not to function correctly. Any damage to the power cord should be repaired or replaced before operating.
Machine will not function, with power
_______ Check all E-Stops to make sure none are engaged
_______ Be sure the film feed door is closed all the way
_______ Check internal drives for error codes
If you check internal drives and one is displaying an error code, contact a tech from where you bought the machine for assistance.
Machine turntable will not stop at home
_______ Bad connection between mast and turntable
_______ Remove four bolts in turntable and check for debris blocking limit switch
_______ If no obstructions, the limit switch may be bad, call a technician.
The limit switch tells the turntable to return to home. If the machine turntable will not find the home position, something related to the limit switch is often the problem.
Film Carriage Does Not Work
_______ Check to be sure cannon plug into film carriage are on properly and not damaged
_______ Check the film carriage chain for breaks or disconnections from gears
_______ Be sure the film carriage is not outside the carriage limit switch
Be sure there is nothing obstructing the film carriage inside the machine and out. Lastly, look for error codes on the internal drive and contact a technician if showing an error.
Stretch film breaks during operation
_______ The correct stretch film being used, machine stretch film is made to stretch more than hand stretch film for better performance
_______ Be sure the stretch film is threaded correctly through the machine
_______ Adjust the turntable speed and tension to the lowest levels possible and see if breaking continues
If tension is lower and breaking continues there may be a problem with the pre-stretched heads on the machine. If lower turntable speed and tension help, slowly increase until the right tension is found as the machine is in operation.
Many things can go wrong with a stretch wrap machine. Use this checklist as a basic guide to quickly find what may be wrong with your stretch wrap machine. For more complex issues or error codes reading on the internal drives, we recommend contacting a qualified technician.
