Packaging system and method with freight rate analysis
View Patent ↗A packaging method includes the step of comparing a total package weight to a freight rate schedule and thereby determining a normal freight rate. The total package weight includes the weight of a container ( 22 ), an article ( 24 ) to be shipped and a normal amount of dunnage. If predetermined criteria are met, the method also includes the step of reducing the amount of dunnage dispensed below that of the normal amount of dunnage such that the total package weight falls within a freight rate that is less than the normal freight rate. The predetermined criteria include one or more of a predetermined percentage above a change in freight rate, a predetermined weight above a threshold weight for an increase in freight weight, and dunnage requirements including void-volume, degree of fill for the void-volume, type of article, weight of article and type of dunnage.
1. A packaging method for packing an article in a container comprising the following steps:
comparing a total package weight that includes the weight of a container, an article and a normal amount of dunnage, to a freight rate schedule and thereby determining a normal freight rate, including using a controller automatically to compare the total package weight to a freight rate schedule, the controller including a computer processor configured to carry out the following steps; where
if predetermined criteria are met, controlling by the computer processor a supply of dunnage to output an amount of dunnage below that of the normal amount of dunnage such that the total package weight falls within a freight rate that is less than the normal freight rate; wherein the predetermined criteria include one or more of a predetermined percentage above a change in freight rate; a predetermined weight above a threshold weight for an increase in freight weight; dunnage requirements including void volume, degree of fill for the void volume, type of article, weight of article and type of dunnage; and
if the predetermined criteria are not met, controlling by the computer processor the supply of dunnage to output the normal amount of dunnage.
2. A method as set forth in claim 1 , wherein the controlling step includes controlling a conversion machine to output the determined amount of dunnage.
3. A method as set forth in claim 1 , wherein the controlling step includes stopping the supply of dunnage from dispensing dunnage when the desired package weight is reached.
4. A method as set forth in claim 1 , comprising the step of weighing the container and the article therein before dispensing dunnage.
5. A method as set forth in claim 1 , comprising the step of weighing the container and the article therein as the dunnage is placed in the container.
6. A method as set forth in claim 1 , comprising the steps of weighing the container after dunnage has been dispensed and removing dunnage until the desired package weight is reached.
7. A packaging system for packing an article in a container based on one or more dunnage requirements, comprising a supply of dunnage and a computer processor configured to carry out the following steps:
comparing a total package weight that includes the weight of a container, an article and a normal amount of dunnage, to a freight rate schedule and thereby determining a normal freight rate, including using a controller automatically to compare the total package weight to a freight rate schedule; where
if predetermined criteria are met, controlling a supply of dunnage to output an amount of dunnage below that of the normal amount of dunnage such that the total package weight falls within a freight rate that is less than the normal freight rate; wherein the predetermined criteria include one or more of a predetermined percentage above a change in freight rate; a predetermined weight above a threshold weight for an increase in freight weight; dunnage requirements including void volume, degree of fill for the void volume, type of article, weight of article and type of dunnage; and
if the predetermined criteria are not met, controlling the supply of dunnage to output the normal amount of dunnage.
8. A system as set forth in claim 7 , wherein the dunnage supply includes multiple types of dunnage, each type having a different density.
9. A system as set forth in claim 7 , wherein the dunnage supply includes a dunnage converter that converts a stock material into a length of dunnage that is relatively less dense than the stock material.
10. A system as set forth in claim 7 , comprising a sensor connectable to the computer processor to transmit sensor data to the computer processor, the computer processor being operable to determine the void volume in the container based on the sensor data.
11. A system as set forth in claim 7 , further comprising one or more of a data storage device; an output device, such as a display; and an input device, such as a pointing device, a keyboard, a bar code scanner, a scale and a sensor for detecting one or more dimensions.
12. A system as set forth in claim 7 , wherein the freight rate schedule includes a plurality of rates and a range of weights associated with each rate.
13. A system as set forth in claim 7 , wherein the freight rate schedule includes a plurality of sets of freight rates for respective container sizes.
