The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.

Inkjet printing systems and methods dynamically control meniscus pressure at a nozzle to more reliably deliver ink to a substrate. The systems and methods include inferring an angle of a longitudinal axis of a printhead relative to the vertical reference axis based on an orientation signal from an orientation sensor, determining a target feed fluid pressure upstream of the nozzle and a target recirculation fluid pressure downstream of the nozzle, thereby to maintain a target pressure differentiation across the nozzle based, at least in part, on the inferred angle of the longitudinal axis, and controlling a variable feed pump speed and a variable recirculation pump speed to obtain the target feed fluid pressure and the target recirculation fluid pressure.

Provided are an ink-jet type vehicle coating machine and an ink-jet type vehicle coating method that enable formation of a uniform coating film thickness at a coating portion including an end of a vehicle. In a state where a longitudinal direction of a nozzle head 53 is orthogonal to a scanning direction, a first nozzle array 55A and a second nozzle array 55B are disposed such that droplets discharged from nozzles 54 of the second nozzle array 55B are discharged to intermediate portions between droplets discharged from nozzles 54 adjacent to each other in the first nozzle array 55A. In addition, on the basis of trajectory data for moving the nozzle head 53, attitude data for keeping the longitudinal direction of the nozzle head 53 perpendicular to a main scanning direction of the nozzle head 53 is formed. An arm control unit 110 controls a robot arm on the basis of the trajectory data and attitude data such that, in a state where the nozzle head 53 performs coating while moving in the main scanning direction, the longitudinal direction of the nozzle head 53 is kept perpendicular to the main scanning direction.

A dispensing system for dispensing hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution and pump the solution at a volumetric flow rate. The dispensing system also includes a valve to control an amount of the gas provided to the pump from the second input, a flow meter to measure the volumetric flow rate of the solution pumped by the pump, and a dispenser to receive the solution from the pump and dispense the solution to create the hot melt adhesive foam.

The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

A control system including a discharge control circuit configured to control an application device such that a coating is discharged from a discharge circuit; a robot control circuit configured to cause an articulated robot to change a position and an orientation of the discharge circuit such that the coating is applied to a workpiece; an application abnormality detection circuit configured to detect an abnormality in an application state of the coating on the basis of at least one of a state of the device or of the robot; an application position calculation circuit configured to calculate an application position of the coating; and an abnormality notification circuit configured to send a notification of a site of an abnormality in the application state on the workpiece on the basis of a detection result of the abnormality in the application state and a calculation result of the application position.
