Abstract

A method of delivering a glutinous substance from a cartridge to an applicator is disclosed. The method comprises receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap is in an open position. The method also comprises moving the pressure cap into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge and to sealingly couple the applicator with a leading end of the cartridge. The method further comprises applying pressure to the glutinous substance in the cartridge through the pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator. Additionally, the method comprises moving the pressure cap into the open position to provide sufficient clearance sufficient for removal of the cartridge from the sleeve through the inlet of the sleeve.

First claim

What is claimed is:

1. A method of delivering a glutinous substance from a cartridge to an applicator, the method comprising steps of:
receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap, located proximate the inlet of the sleeve, is in an open position, wherein the cartridge has a leading end and a trailing end;
moving the pressure cap, located proximate the inlet of the sleeve, into a closed position to sealingly couple the pressure cap with the trailing end of the cartridge and to sealingly couple the applicator with the leading end of the cartridge;
applying pressure to the glutinous substance in the cartridge through a pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator;
moving the pressure cap into the open position to provide clearance sufficient for removal of the cartridge from the sleeve through the inlet of the sleeve; and
releasably locking the pressure cap in the closed position;
wherein:
the pressure cap is pivotally coupled to an arm;
the step of moving the pressure cap into the closed position comprises rotating the arm in a first rotational direction about an axis that is fixed relative to the sleeve and that is perpendicular to a central axis of the sleeve; and
the step of moving the pressure cap into the open position comprises rotating the arm about the axis in a second rotational direction, opposite the first rotational direction.

2. The method according to claim 1 , wherein the step of moving the pressure cap into the closed position comprises torsionally biasing the pressure cap relative to the arm.

3. The method according to claim 1 , wherein:
the step of moving the pressure cap into the closed position comprises pneumatically causing an actuator coupled to the pressure cap, to have a first length; and
the step of releasably locking the pressure cap in the closed position comprises mechanically locking the pressure cap in the closed position.

4. The method according to claim 3 , wherein:
a lock mechanism is used to mechanically lock the pressure cap in the closed position; and
when the lock mechanism is in a locked position, the lock mechanism remains in the locked position if the actuator loses pressure.

5. The method according to claim 3 , wherein:
moving the pressure cap into the open position comprises pneumatically causing the actuator to have a second length different from the first length.

6. The method according to claim 5 , further comprising disabling operation of the actuator while pressure is applied to the glutinous substance in the cartridge through the pressure input of the pressure cap.

7. The method according to claim 1 , wherein the step of applying pressure to the glutinous substance in the cartridge through the pressure input of the pressure cap comprises introducing a pressurized gas into the cartridge through the pressure input.

8. The method according to claim 7 , further comprising sensing a temperature of the glutinous substance in the applicator, wherein the pressure applied to the glutinous substance in the cartridge through the pressure input of the pressure cap varies responsive to, at least in part, the temperature of the glutinous substance sensed in the applicator.

9. The method according to claim 7 , further comprising sensing a pressure of the glutinous substance in the applicator, wherein the pressure applied to the glutinous substance in the cartridge through the pressure input of the pressure cap varies responsive to, at least in part, the pressure of the glutinous substance sensed in the applicator.

10. The method according to claim 1 , further comprising applying pressure to the cartridge inside the sleeve to eject the cartridge from within the sleeve through the inlet of the sleeve when the pressure cap is in the open position.

11. The method according to claim 1 , further comprising a step of releasably retaining the applicator relative to the sleeve.

12. The method according to claim 11 , wherein the step of releasably retaining the applicator relative to the sleeve comprises a step of locating a receptacle interface of the applicator within a receptacle, fixed relative to the sleeve, with a running fit.

13. The method according to claim 12 , wherein the step of locating the receptacle interface of the applicator within the receptacle with the running fit comprises:
3-D printing the receptacle interface of the applicator into a shape larger than the receptacle; and
machining away a portion of the receptacle interface of the applicator.

14. The method according to claim 8 , further comprising sensing a pressure of the glutinous substance in the applicator, wherein the pressure applied to the glutinous substance in the cartridge through the pressure input of the pressure cap varies responsive to, at least in part, the pressure of the glutinous substance sensed in the applicator.

15. The method according to claim 2 , wherein the step of applying pressure to the glutinous substance in the cartridge through the pressure input of the pressure cap comprises introducing a pressurized gas into the cartridge through the pressure input.

16. The method according to claim 7 , further comprising applying pressure to the cartridge inside the sleeve to eject the cartridge from within the sleeve through the inlet of the sleeve when the pressure cap is in the open position.

17. The method according to claim 2 , further comprising releasably locking the pressure cap in the closed position.

18. The method according to claim 4 , wherein the step of moving the pressure cap into the open position comprises pneumatically causing the actuator to have a second length different from the first length.

19. A method of delivering a glutinous substance from a cartridge to an applicator, the method comprising:
receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap, located proximate the inlet of the sleeve, is in an open position, wherein the cartridge has a leading end and a trailing end;
moving the pressure cap, located proximate the inlet of the sleeve, into a closed position to sealingly couple the pressure cap with the trailing end of the cartridge and to sealingly couple the applicator with the leading end of the cartridge;
applying pressure to the glutinous substance in the cartridge through a pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator;
moving the pressure cap into the open position to provide clearance sufficient for removal of the cartridge from the sleeve through the inlet of the sleeve; and
rotating a retainer, relative to a receptacle that is cross-sectionally complementary to a receptacle interface of the applicator, to releasably retain the applicator so that the applicator is sealingly coupled with the leading end of the cartridge with the pressure cap in the closed position.

20. The method according to claim 19 , further comprising releasably locking the pressure cap in the closed position, wherein:
the pressure cap is pivotally coupled to an arm;
the step of moving the pressure cap into the closed position comprises rotating the arm in a first rotational direction about an axis that is fixed relative to the sleeve and that is perpendicular to a central axis of the sleeve; and
the step of moving the pressure cap into the open position comprises rotating the arm about the axis in a second rotational direction, opposite the first rotational direction.
