Abstract

Claims (54)

1. A spooler for taking up a pouch package web output from a pouch package web source comprising:

a support structure;

a rotatable spindle secured with respect to the support structure for supporting a spool mounted thereon;

a drive apparatus in power-transmission relationship with the spindle for powering spindle rotation; and

a control apparatus operative to stop the drive apparatus responsive to stoppage of pouch package web output from the pouch package web source and to stop the drive apparatus responsive to a reduction in tension on the pouch package web, the control apparatus comprising:

a movable arm pivotably attached to the support structure including a roller which rides on the pouch package web, said arm being supported by the pouch package web such that the arm is movable to a first position responsive to increased pouch package we tension resulting from stoppage at the pouch package web output in combination with continued pouch package web take up onto the spool and the arm is movable to a second position responsive to a reduction in tension on the pouch package web;

a switch operable to power the drive apparatus when the arm is between the first and second positions and alternatively, to de-power the drive apparatus when the arm is at the first or second position; and

a cam which acts on the switch to de-power the drive apparatus when the arm is at the first or second position.

2. The spooler of claim 1 further comprising a spool mounted on the spindle.

3. The spooler of claim 2 wherein the spool is releasably mounted on the spindle.

4. The spooler of claim 3 wherein the spool comprises:

a hub defining a spindle-receiving opening; and

a pair of spaced apart sidewalls extending radially outward from the hub.

5. The spooler of claim 1 in combination with a rack for receiving at least one spool.

6. The spooler of claim 1 wherein the cam is associated with the arm and has a cam surface, said cam being displaced by movement of the arm such that the cam surface operates the switch to stop the drive apparatus when the arm is at the first of second position.

7. A method for management of a pouch package web output from a pouch package web source comprising:

positioning a spooler adjacent to the pouch package web source;

associating the pouch package web from the pouch package web source with a spool mounted on spooler;

outputting the pouch package web from the pouch package web source;

rotating the spool with the spooler to wind the pouch package we into a roll on the spool;

moving a tensioner in contact with the pouch package web to a first position responsive to an increase in pouch package web tension from stopping pouch package web outputting in combination with continued spool rotating or, alternatively, moving the tensioner to a second position responsive to a decrease in pouch package web tension; and

stopping spool rotation by contacting a switch with a cam responsive to tensioner movement to the first or, alternatively, the second position such that the switch operates to stop spool rotating when the tensioner is at the first or second position.

8. The method of claim 7 further comprising:

severing the pouch package web, said severing resulting in loss of the pouch package web tension; and

stopping spool rotation further includes contacting the switch with the cam such that the switch is opened to stop spool rotating when the tensioner is at the second position.

9. The method of claim 7 further comprising severing of the pouch package web output from the pouch package web source once an amount of the pouch package web is wound onto the spool.

10. The method of claim 9 further comprising removing the spool from the spooler, said spool including the amount of pouch package web.

11. The method of claim 10 further comprising placing the removed spool onto a storage rack.

12. A spooler for taking up a pouch package web output from a pouch package web source comprising:

a support structure;

a rotatable spindle secured with respect to the support structure for supporting a spool mounted thereon;

a drive apparatus in power-transmission relationship with the spindle for powering spindle rotation; and

control apparatus operative to stop the drive apparatus responsive to stoppage of pouch package web output from the pouch package web source and to stop the drive apparatus responsive to a reduction in tension on the pouch package web, the control apparatus comprising:

a movable arm pivotably attached to the support structure including a roller which rides on the pouch package web, said arm being supported by the pouch package web such that the arm is movable to a first position responsive to increased pouch package web tension resulting from stoppage of the pouch package web output in combination with continued pouch package web take up onto the spool and the arm is movable to a second position responsive to a reduction in i:ension on the pouch package web;

a switch operable to power the drive apparatus when the arm is between the first and second positions and altemative.y, to de-power the drive apparatus when the arm is at the first or second position; and

a contact element associated with the arm which cooperates with the switch to de-power the drive apparatus when the arm is at the first or second position.

13. The spooler of claim 12 further comprising a spool mounted on the spindle.

14. The spooler of claim 13 wherein the spool is rekasably mounted on the spindle.

15. The spooler of claim 14 wherein the spool comprises:

a hub defining a spindle-receiving opening; and

a pair of spaced apart sidewalls extending radially outward from the hub.

16. The spooler of claim 12 in combination with a rack for receiving at least one spool.

17. A method for management of a pouch package web output from a pouch package web source comprising:

positioning a spooler adjacent to the pouch package web source;

associating the pouch package web from the pouch package web source with a spool mounted on the spooler;

outputting the pouch package web from the pouch package web source;

rotating the spool with the spooler to wind the pouch package web into a roll on the spool;

moving a tensioner in contact with the pouch package web to a first position responsive to an increase in pouch package web tension from stopping pouch package web outputting in combination with continued spool rotating or, alternatively, moving the tensioner to a second position responsive to a decrease in pouch package web tension; and

stopping spool rotation by contacting a switch with a contact-element associated with the ternsioner responsive to tensioner movement to the first or, alternatively, the second position such that the switch operates to stop spool rotating when the tensioner is at the first or second position.

18. The method of claim 17 further comprising:

severing the pouch package web, said severing resulting in loss of the pouch package web tension; and

stopping spool rotation further includes contacting the switch with the contact element such that the switch is opened to stop spool rotating when the tensioner is at the second position.

19. The method of claim 18 further comprising removing the spool from the spooler, said spool including an amount of pouch package web.

20. The method of claim 19 further comprising placing the removed spool onto a storage rack.
