Machine generated wrap data

摘要

A method for generating data with a wrapping machine during wrapping of a load includes measuring a length of packaging material dispensed during wrapping of the load with a sensing assembly on the wrapping machine. The method further includes obtaining a value indicative of a weight of the packaging material per unit of length and determining a weight of the packaging material dispensed on the wrapped load based on the measured length and the obtained value without removing the packaging material from the load. The determined weight of the packaging material is displayed on a display device.

主权项

1. A wrapping machine for wrapping a load with packaging material, comprising:
a packaging material dispenser configured to dispense packaging material around the load; at least one sensing assembly sensing a plurality of relative revolutions between the packaging material dispenser and the load and a height of the packaging material dispenser relative to the load during each relative revolution among the plurality of relative revolutions when wrapping the load with packaging material; a display device; and a controller communicating with the sensing assembly and the display device to determine a height of the packaging material dispenser during each of the plurality of relative revolutions when wrapping the load with packaging material; the controller determining the number of layers applied to a face of the load at a plurality of heights on the load based on an effective height of the packaging material as measured between first and second edges of the packaging material, the sensed relative revolutions and the determined height of the packaging material dispenser during each of the plurality of relative revolutions, wherein the number of layers applied to the face of the load at the plurality of heights is representative of a thickness of packaging material applied to the face of the load at the plurality of heights; and the controller further using the determined number of layers applied to the face of the load at the plurality of heights to generate information representative of the number of layers applied to the face of the load at one or more of the plurality of heights and controlling the display device to display the information representative of the number of layers applied to the face of the load at the one or more of the plurality of heights.
