Abstract

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

First claim

What is claimed is:

1. A system, comprising:
a film processing module including an upper multi-functional assembly and a base, the film processing module moveably mounted to a supporting rail; and
a processor and memory in communication with the film processing module to:
dynamically coordinate movement of the film processing module relative to a moving web of film, and
perform a function on the web of film that extends between the upper multi-functional assembly and the base with the film processing module,

wherein the film processing module includes, and is electrically powered by, a battery, and
a registration sensor adjacent to the web of film, the registration sensor to detect demarcations on the web of film,
wherein the upper multi-functional assembly is adapted to clamp, cut, and seal the film and the film processing module includes a linear actuator to move the upper multi-functional assembly relative to the base.

2. The system of claim 1 , wherein the processor and memory are further configured to determine a frequency of the demarcations as the demarcations pass the registration sensor and an offset between the demarcations.

3. The system of claim 2 , wherein the processor and memory are configured to dynamically coordinate movement of the film processing module relative to a moving web of film based on the offset.

4. The system of claim 1 , wherein the registration sensor is an optical sensor.

5. The system of claim 1 , wherein the film processing module is electrically powered by a bus disposed concentrically to the supporting rail.

6. The system of claim 1 , wherein the supporting rail includes a plurality of rail sensors in communication with the processor and the processor is further configured to monitor a location of the film processing module along the supporting rail.

7. The system of claim 6 , wherein the supporting rail is oblong.

8. The system of claim 7 , wherein the web of film travels along an axis parallel to the supporting rail.

9. The system of claim 1 , wherein the film processing module includes a module sensor in communication with the processor, the processor further configured to determine an offset of the film processing module relative to the demarcations on the web of film based on information from the module sensor.

10. The system of claim 9 , wherein the processor is further configured to move the film processing module relative to the web of film to close the offset.

11. The system of claim 10 , wherein the processor is further configured to cut the web of film with the processing module when the offset is closed.

12. The system of claim 1 , wherein the film processing module is one of a plurality of film processing modules and the processor is further configured to dynamically coordinate movements of the film processing modules relative to one another.

13. A method for producing film products, the method comprising:
dynamically coordinating, with a processor, movement of a plurality of film processing modules relative to a moving web of film;
instructing, with the processor, at least one film processing module of the plurality of film processing modules to perform a function on the web of film;
controlling, with the processor, an air controller of the at least one film processing module to draw a vacuum to retain a film product formed from the web of film;
and determining, with the processor, an offset of the plurality of film processing modules relative to demarcations on the web of film based on information from a module sensor mounted in each of the plurality of film processing modules.

14. The method of claim 13 , further comprising instructing, with the processor, the at least one film processing module to maintain contact between a cutting mechanism of the at least one film processing module and the web of film for a predetermined period of time.

15. The method of claim 14 , wherein the cutting mechanism includes one or more of a cutting wire and a heatable knife.

16. The method of claim 13 , further comprising instructing, with the processor, the plurality of film processing modules to move relative to the web of film to close the offset.

17. The method of claim 16 , further comprising instructing, with the processor, the at least one film processing module to cut the web of film with the at least one film processing module when the offset is closed.

18. A system, comprising:
a film processing module moveably mounted to a supporting rail; and
a processor and memory in communication with the film processing module to:
dynamically coordinate movement of the film processing module relative to a moving web of film, and
perform a function on the web of film with the film processing module,

wherein the processor is further configured to control an air controller of the film processing module to draw a vacuum to retain a film product formed from the web of film, and
wherein the film processing module includes a module sensor in communication with the processor and the processor is further configured to determine an offset of the film processing module relative to a demarcation on the web of film based on information from the module sensor.

19. The system of claim 18 , wherein the film processing module is one of a plurality of film processing modules and the processor is further configured to dynamically coordinate movements of the film processing modules relative to one another.

20. A system, comprising:
a film processing module including an upper multi-functional assembly and a base, the film processing module electrically powered by a bus disposed concentrically to a supporting rail and moveably mounted to the supporting rail; and
a processor and memory in communication with the film processing module to:
dynamically coordinate movement of the film processing module relative to a moving web of film, and
perform a function on the web of film that extends between the upper multi-functional assembly and the base with the film processing module,

wherein the film processing module includes, and is electrically powered by, a battery, and
a registration sensor adjacent to the web of film, the registration sensor to detect demarcations on the web of film.

21. A system, comprising:
a film processing module including an upper multi-functional assembly and a base, the film processing module moveably mounted to a supporting rail; and
a processor and memory in communication with the film processing module to:
dynamically coordinate movement of the film processing module relative to a moving web of film, and
perform a function on the web of film that extends between the upper multi-functional assembly and the base with the film processing module,

wherein the film processing module includes, and is electrically powered by, a battery, and
a registration sensor adjacent to the web of film, the registration sensor to detect demarcations on the web of film,
wherein the supporting rail includes a plurality of rail sensors in communication with the processor and the processor is further configured to monitor a location of the film processing module along the supporting rail.

22. A system, comprising:
a film processing module including an upper multi-functional assembly and a base, the film processing module moveably mounted to a supporting rail; and
a processor and memory in communication with the film processing module to:
dynamically coordinate movement of the film processing module relative to a moving web of f
