Abstract

Claims (24)

1. A system for applying a two-part adhesive to a substrate, the system comprising:

a carrier;

at least one wheel rotationally coupled to the carrier;

a first receptacle for storing a first compound, the first receptacle having an outlet in communication with the first compound;

a second receptacle for storing a second compound, the second receptacle having an outlet in communication with the second compound;

a prime mover mounted on the carrier and connected to a gear box through a rotatable shaft, wherein the gear box transfers a driving torque from the prime mover to a first rotatable shaft coupled to a first pump and a second rotatable shaft coupled to a second pump; wherein the gear box and the first and second rotatable shaft do not come in contact with the first and the second compound,

the first pump having an inlet in communication with the outlet of the first receptacle and having an outlet, the first pump mounted on the carrier and driven by the prime mover to draw the first compound from the first receptacle and pump through the outlet of the first pump;

the second pump having an inlet in communication with the outlet of the second receptacle and having an outlet, the second pump mounted on the carrier and driven by the prime mover to draw the second compound from the second receptacle and pump through the outlet of the second pump;

a first manifold attached to a front of a frame, wherein the frame is sized to receive the first compound and the second compound of a two-part compound, and the first manifold is having an inlet in communication with the outlet of the first pump and having a plurality of outlets;

a second manifold attached to a front of a frame, wherein the frame is sized to receive the first compound and the second compound of a two-part compound, and the second manifold is having an inlet in communication with the outlet of the second pump and having a plurality of outlets;

a plurality of applicators, each applicator having a first inlet, a second inlet, and an outlet, wherein the first inlet of each applicator is in communication with at least one outlet of the first manifold and the second inlet of each applicator is in communication with at least one outlet of the second manifold, wherein the plurality of applicators are configured to mix the first compound with the second compound to form the two-part adhesive, and

wherein the mixed two-part adhesive is discharged on areas that can exceed 40 inches in width from the outlets of the plurality of applicators onto the substrate in substantially parallel beads.

2. The system of claim 1 wherein the first compound and the second compound have average viscosities between about 2500 Pas and about 7000 Pas.

3. The system of claim 1 further comprising a radio frequency identifier disposed on the first receptacle and a radio frequency receiver interconnected to the prime mover, wherein the radio frequency receiver communicates with the radio frequency identifier to validate the first receptacle.

4. The system of claim 1 further comprising a tray for supporting the first and second receptacles, the tray having a first slot having a first shape and a second slot having a second shape different from the first shape, wherein the first receptacle has substantially the first shape and the second receptacle has substantially the second shape.

5. The system of claim 1 wherein the first pump and the second pump are integrated into a dual pump assembly.

6. The device of claim 1 wherein the first manifold and the second manifold are formed as a single, dual channel manifold.

7. The device of claim 1 wherein the plurality of applicators each include a dual manifold, an orifice restrictor attached to the dual manifold, and a mixing wand attached to the orifice restrictor.

8. The device of claim 7 wherein the dual manifold includes the first inlet and the second inlet of the applicator and includes a first outlet in communication with the orifice restrictor, a second outlet in communication with the orifice restrictor, and a tab member disposed between the first and second outlets, and wherein the orifice restrictor includes a first orifice in communication with the first outlet of the dual manifold, a second orifice in communication with the second outlet of the dual manifold, and a slot that receives the tab member.

9. The device of claim 8 wherein the first orifice has a diameter different than a diameter of the second orifice.

10. The device of claim 9 wherein the diameter of the first orifice is a function of the material characteristics of the first compound and the diameter of the second orifice is a function of the material characteristics of the second compound.

11. The device of claim 10 wherein the mixing wand is connected to the orifice restrictor and has at a distal end the outlet of the applicator.

12. The device of claim 11 further comprising a rotary valve disposed between the dual manifold and the first and second manifolds, the rotary valve configured to control a flow of the first compound and the second compound from the first and second manifolds, respectively, to the dual manifold.

13. The device of claim 1 further comprising a first ball valve disposed between the first manifold and the first pump and a second ball valve disposed between the second manifold and the second pump.
