Pallet Wrap Machine Monitor

摘要

A system, method and kit permitting more accurate determination of film usage in a pallet wrap machine involves rotary encoders that engage with the actual film, rather than a pre-stretch or stretch roller. At least one rotary encoder engages with unstretched film before a pre-stretch roller takes up the film and at least one rotary encoder engages with stretched film after the film leaves the stretch roller. Slippage of the film on the rollers, which is a common occurrence, is not a factor that affects the data generated by the rotary encoders.

主权项

1. A system for monitoring and/or improving stretch film usage in a pallet wrap machine, the system comprising:
a plurality of rotary encoders configured to be contactable with stretch film in a pallet wrap machine, at least one of the plurality of rotary encoders configured to contact unstretched stretch film and at least one of the plurality of rotary encoders configured to contact stretched stretch film in the pallet wrap machine; and, a controller in communication with the plurality of rotary encoders, the controller configured to receive rotational data generated by rotation of the rotary encoders, wherein the rotation of the rotary encoders is caused by engagement of the rotary encoders with the stretch film moving in the machine and the rotational data from any one rotary encoder is correlated to a length of stretch film that has passed by the any one rotary encoder, and wherein an amount of stretch film pulled off a roll of stretch film in the machine is determined from rotational data from the at least one rotary encoder configured to contact unstretched stretch film and/or an amount of stretching of the stretch film is determined by comparing the rotational data from the at least one rotary encoder configured to contact unstretched stretch film to rotational data from the at least one rotary encoder configured to contact stretched stretch film.
