An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

The present disclosure describes a method and system for controlling dispensing of adhesive from an applicator. The method includes pumping adhesive from a plurality of pump assemblies to a plurality of dispensing modules and measuring current draw from each of the plurality of pump assemblies. The method also includes determining an adjustment to an operating speed of each of the plurality of pump assemblies individually based on their respective current draws and adjusting the operating speed of each of the plurality of pump assemblies individually.

A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.

The apparatus (100) comprises a bracket (104), comprising an opening (142) that has a central axis (110), and a tubular sleeve (108), coupled to the bracket (104) via the opening (142) and rotatable relative to the bracket (104) about the central axis (110). The apparatus (100) further comprises a valve assembly (112), comprising a valve body (140), fixed to the tubular sleeve (108) and rotatable relative to the bracket (104) together with the tubular sleeve (108), and a valve (144), internal to the valve body (140). The apparatus (100) also comprises a linear actuator (120), configured to position the valve (144) relative to the valve body (140). The apparatus (100) further comprises a nozzle (118), fixed to the valve body (140) and rotatable relative to the bracket (104) together with the valve body (140).

Fluid applicators with precise volume dispensing control for dispensing fluids such as a disinfectant in a controlled manner. Such fluid applicators may include a barrel including a sidewall having an inside surface defining a chamber for retaining a fluid, an end press, a push rod disposed within the chamber, the push rod having a push button and a piercing tip, a cap attached to a port via a hinge to cover a hydrophobic filter disposed on the sidewall of the chamber, a one-way valve disposed on the outlet on a distal end of the barrel, a disinfectant disposed within the chamber; a housing having a base and an open proximal end; and a fluid applicator sponge disposed in the base of the housing. An alternate fluid may include a deformable end press, a plurality of volume scale markings on an outer surface of the barrel, a push rod, a one-way valve and applicator sponge.

A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.

An applicator for dispensing adhesive is disclosed. The applicator includes a manifold, at least one dispensing module coupled to the manifold, a supply channel configured to contain at least a portion of the adhesive, a recirculation channel configured to contain at least a portion of the adhesive, and a recirculation pump assembly connected to the manifold. The recirculation pump assembly includes an inlet in fluid communication with the recirculation channel, an outlet in fluid communication with the supply channel, a gear assembly, and a drive motor coupled to the gear assembly and operable to pump the adhesive, where the drive motor is configured to operate at an adjustable number of revolutions per minute (RPM). The recirculation pump assembly can be configured to move at least a portion of the adhesive from the recirculation channel to the supply channel, such that a first pressure of the adhesive in the recirculation channel is substantially equal to a second pressure of the adhesive in the supply channel.

A display where water is applied onto the screen of a visual display monitor and graphics are presented on the display that coincides with the applied water is described. The timing of the water being applied to the screen and the playing of the graphics may be orchestrated such that the applied water seems to create the presented graphics. A controller may be used to control the water and the display.

An improved system for applying a coating to a sheet is disclosed. The system allows precise control of the actuation of the valves and movement of the nozzle to create a plurality of coating profiles. The system includes a controller, which is used to actuate the valves to begin and terminate the flow of material onto the sheet through a nozzle. In addition, the controller may move the nozzle from its operative position to an inoperative position away from the sheet. In some embodiments, a fluid displacement mechanism is used. The controller is also able to coat the opposite side of the sheet. Registration of the coating can be programmed to be in exact alignment, or advanced or delayed by a specific amount.

A fluid applicator configured to apply a fluid to at least one substrate feature includes a manifold plate having an inflow orifice and a manifold reservoir. A distributor plate is coupled with the manifold plate. The distributor plate includes a distributor surface extending across the manifold reservoir, and a distributor port array spread across the distributor surface and in communication with the manifold reservoir. A compressible reticulated media is configured for applying the fluid to the at least one substrate feature. The compressible reticulated media includes an input interface coupled along the distributor surface, and a substrate interface having an applicator profile corresponding to a feature profile of the at least one substrate feature. Reticulations extend from the input interface to the substrate interface, and the reticulations are distributed across the substrate interface.
