Abstract

An apparatus for inflating and sealing packing cushions utilizes a controller adapted for acquiring information from preconfigured film material and automatically setting one or more operation parameters suitable for inflating and sealing the film. The controller can avoid or limit the need for user input, thus simplifying use of the apparatus.

Claims

1. An apparatus for inflating and sealing packing cushions from a supply of preconfigured film material having a plurality of chambers, the apparatus comprising a feed mechanism for feeding the film material along a path, an inflation mechanism for injecting inflation gas into the chambers, and a sealing mechanism for sealing the chambers, wherein the apparatus comprises a controller in communication with a reader for determining at least one property of the preconfigured film material from a data source associated with the preconfigured film material when the preconfigured film material is positioned in proximity to the apparatus;

and

wherein the reader is a radio frequency identification (RFID) tag reader for obtaining information from an RFID tag present on the film supply.

2. The apparatus of claim 1 wherein the sealing mechanism comprises a sealing element and a backing surface.

3. The apparatus of claim 2 wherein the sealing element comprises a heated rod.

4. The apparatus of claim 2 wherein the sealing element comprises a heated roller.

5. The apparatus of claim 2 wherein the backing surface comprises a wheel.

6. The apparatus of claim 2 wherein the backing surface is constructed from a resilient material.

7. The apparatus of claim 1 wherein the preconfigured film material has a longitudinally extending channel, the apparatus further comprising an elongate member adapted for insertion into the longitudinally extending channel.

8. The apparatus of claim 7, wherein the elongate member has at least one opening for injecting inflation gas into the longitudinally extending channel.

9. The apparatus of claim 1, wherein the controller obtains information from the supply of film when the supply is placed in the operating position.

10. The apparatus of claim 1, wherein the controller obtains information from the supply of film when the supply is positioned within a predetermined distance from the apparatus.

11. An apparatus for inflating and sealing packing cushions from a supply of preconfigured film material having a plurality of chambers, the apparatus comprising a feed mechanism for feeding the film material along a path, an inflation mechanism for injecting inflation gas into the chambers, and a sealing mechanism for sealing the chambers, wherein the apparatus comprises a controller in communication with a reader for determining at least one property of the preconfigured film material from a data source associated with the preconfigured film material when the preconfigured film material is positioned in proximity to the apparatus;

and

wherein the sealing mechanism comprises a pair of opposed belts for carrying the film past at least one heated block.

12. The apparatus of claim 11, wherein the reader is a bar code reader for obtaining information from a bar code present on the film supply.
