Abstract

A monitoring system for monitoring one or more packaging material conversion machines includes one or more sensors for monitoring one or more operating characteristics of the one or more conversion machines. The system also includes a controller in communication with the one or more sensors. The controller evaluates the one or more operating characteristics of the one or more conversion machines to thereby provide diagnostic, inventory and machine usage information. In addition, a method of monitoring one or more packaging material conversion machines includes sensing an operating characteristic of the one or more conversion machines and evaluating the operating characteristic of the one or more conversion machines. The sensed operating characteristics may be evaluated either local to the conversion machines or at a remote site, thereby providing a substantial amount of flexibility.

Claims

1. A method of providing dunnage to a container for packing an object that is in the container, the method comprising the steps of:

measuring the void volume of the container within which the object is placed using a probe;

determining the void volume from measurement information output from the probe;

determining an amount of dunnage for packing the object in the container based on the void volume; and

dispensing the determined amount of dunnage from a supply of dunnage for packing the object in the container.

2. A method as set forth in claim 1, wherein the dispensing step includes controlling a conversion machine to convert sheet stock material into the determined amount of dunnage for the container.

3. A method as set forth in claim 2, further comprising providing a cushioning conversion machine having a conversion assembly which converts the sheet stock material into a three-dimensional strip of dunnage, the conversion assembly including a forming assembly which forms the sheet stock material into a strip of dunnage and a feed assembly which feeds the stock material through the forming assembly, a stock supply assembly, positioned upstream of the conversion assembly which supplies the stock material to the conversion assembly;

a cutting assembly, positioned downstream of the conversion assembly, which cuts a section of the strip of dunnage; and

controlling the feed assembly and the cutting assembly to produce the determined amount of dunnage.
