Abstract: According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.

Abstract: A suck back type intermittent coating system including a valve mechanism, a valve manipulating mechanism, and a solenoid valve for controlling the operation of the valve manipulating mechanism; and a control device that inputs therein a pulse signal indicative of the travel state (travel speed, etc.) of a base material traveling along a coating line, and outputs an electrical command to the solenoid valve. A displacement sensor for detecting a displacement of the movable valve body of the valve mechanism is provided so that the operation of the valve manipulating mechanism is remotely controlled by a command signal to the solenoid valve; and with a computer having a feedback function that issues a correction signal to the operation of the solenoid valve confirmation and tally of the operation of a coating gun module is performed even when away from a production line.

Abstract: A method of manipulating a brush relative to a brush-arm assembly of an end-effector comprises locating a carriage in one of a first position or a second position relative to a stationary component. The method also comprises, with the carriage in one of the first position or the second position, different from the first position, relative to the stationary component, locating the brush-arm assembly of the end-effector with respect to the stationary component so that the brush-arm assembly is in contact with the stationary component. The method further comprises moving the carriage in a second direction toward the stationary component, from the first position to a third position, to load the brush onto the brush-arm assembly, or moving the carriage in a first direction away from the stationary component from the second position to the first position to unload the brush from the brush-arm assembly.

Abstract: A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

Abstract: A check valve system includes a housing, a blocking element, and a biasing member. The housing has a passageway therethrough, the passageway including a first portion and a second portion, the first portion having a diameter that is less than a diameter of the second portion so as to form a stepped portion. The blocking element is disposed within the second portion of the passageway. The biasing member is disposed within the second portion of the passageway and configured to maintain the blocking element in contact with the stepped portion when under compression. The housing, the blocking element and the biasing member being obtainable by substantially simultaneously 3D printing, so as to be formed from one or more 3D printable materials.

Abstract: A dispensing system receives liquid material and process air. The dispensing system includes a manifold body having a liquid material passage and a process air passage. The dispensing system includes a heating member received in the manifold body. The heating member has an upper portion, a lower portion, an outer surface, and a groove in the outer surface. The groove may extend between the upper portion and the lower portion and form at least a portion of the process air passage. The dispensing system may further include a nozzle configured to dispense the liquid material. The heating member may be configured to heat the process air as the process air passes through the groove and heat the liquid material through contact of the outer surface of the heating member with the manifold body.
