Abstract:
An apparatus for dispensing adhesive, comprising:dispensing means for dispensing adhesive, the dispensing means having:regulating means for regulating a high pressure air supply to the dispensing means,positioning means for positioning the high pressure air supply with respect to the adhesive,actuating means for simultaneously actuating the dispensing of adhesive and high pressure air to form a predetermined spray pattern of the adhesive;high pressure air supply means connected to said dispensing means, the high pressure air supply means including:control means for controlling the high pressure air supply;adhesive supply means connected to said dispensing means, the adhesive supply means including:a hermetically sealed flexible bladder in which the adhesive is disposed,a container for containing the flexible bladder, anda hermetically sealed coupling extending from the flexible bladder through the container and providing a hermetically sealed conduit through which the adhesive is removed from the bladder,venting means for venting gas from the hermetically sealed conduit,elevational means for elevating the adhesive supply means;bracing means for bracing the hermetically sealed coupling at the elevational means;adhesive delivery means for delivering the adhesive from the hermetically sealed coupling to the dispensing means, the adhesive delivery means having:a hermetically sealed vertically disposed conduit constructed and arranged as a riser for delivery of the adhesive, the riser having:fixed piping having a first relatively large flow path,a quick disconnect coupling disposed between and interconnecting the hermetically sealed coupling of the container and the fixed piping,indicator means in communication with the fixed piping to indicate the flow of adhesive,first control means operatively associated with the fixed piping to control the flow of the adhesive through the fixed piping, the first control means including a ball valve;restricting means connected to the fixed piping for restricting the passageway for the flow of the adhesive through the fixed piping;flexible piping means connected to the fixed piping downstream from the restricting means and operatively associated with said dispensing means, the flexible piping means having a second flow path relatively narrower than the first flow path;bleed means connected to the flexible piping means for bleeding gas from the flexible piping downstream from the restricting means;second control means for controlling simultaneously the high pressure air and the adhesive to enable dispensing of the adhesive in a predetermined pattern; andclosure means constructed and arranged for closing off the hermetically sealed coupling and the hermetically sealed conduit when the coupling and conduit are uncoupled from each other.
