A powder-dispensing device in the form of a dense-phase powder pump or of a powder injector is provided to deliver coating powder from a powder reservoir to a powder-spraying device. To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, a control device is integrated in the powder-dispensing device or is connected, in particular directly, to the powder-dispensing device and is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device.

Apparatus and method for a painting machine are provided. The painting machine may include an end effector controlled by custom software. The painting machine may include a self-contained medium circulation system. The custom control software may be capable of coordinated n-axis manipulation of an end. Illustrative end effectors may include an inkjet head, brush, air brush or any suitable tool for applying ink, paint, color and/or texture to a surface. For example an end effector may utilize oil-based ink or ultraviolet-cured ink. Illustrative surfaces may include canvas, paper, brick, glass etc. The custom control software may control manipulation of the end effector based on a variety of electronic inputs. The custom software may manipulate different end effectors in different ways depending on the input data, type of ink/paint being used, type of surface receiving the ink/paint or any other variable.

Disclosed is a device for pressurizing a viscous fluid contained in a drum, the device includes a follower plate vertically movable along a perpendicular axis passing through the center of the drum, the follower plate: is movable between a first position outside the drum and a second position inside the drum, to exert pressure on the viscous fluid; has a transfer port intended to be connected to a means of pumping capable of transferring the pressurized fluid. The device further includes an energy storage unit and restoration connected to the support system, the storage unit being capable of storing energy under the effect of the pressure exerted by the support system and of restoring it to the follower plate in order to maintain the viscous fluid under pressure.

A device for performing a surface coating of pieces is disclosed. The device comprises a housing including one leak-tight cavity containing a drum, heating means, at least one water inlet conduit and one dyeing agent inlet conduit, and a recovery tank and a fluid recirculation circuit from said recovery tank to said leak-tight cavity and drum. The leak-tight cavity includes a first level sensor connected to a control device, such that the entry of water to the leak-tight cavity is interrupted when a specific level is reached inside the cavity, and the recovery tank includes at least a second level sensor connected to the control device, such that the entry of water and dyeing agent to the leak-tight cavity is interrupted if a specific level is exceeded inside the recovery tank.

One general aspect includes a liquid dispenser with a mount having a mount aperture. A liquid flow path assembly is removably secured to the mount and has an inlet configured to receive liquid, an outlet configured to dispense liquid and a passageway fluidly coupling the inlet to the outlet. A third aperture apart from the inlet and the outlet is fluidly coupled to the passageway and forming a valve guide. The liquid flow path assembly is disposed on the mount to align the third aperture with the mount aperture. An elongated valve has a valve stem guided by the valve guide and extends through the third aperture and the mount aperture. A latch assembly secures the liquid flow path assembly to the mount.

Problems: To provide a cable unit that can save space for a work space, and a liquid material supply device and an application device including the cable unit. Solution: A cable unit 30 that detachably and electrically connects a discharge head 10 configured to discharge a liquid material with a relative-moving robot 20 configured to carry out relative movement between the discharge head 10 and a workpiece 25, the cable unit having a dispense controller 33 configured to control a discharge operation of the discharge head 10, and a liquid material supply device and an application device including the cable unit.

Provided is a method and apparatus for treating a substrate with a liquid. The substrate treating method comprises a pre-treating step for supplying the treatment liquid containing hydrogen fluoride (HF) to the substrate and treating the substrate before the surface modification step and a surface modification step for supplying an alkene-based chemical onto a substrate to change the surface of the substrate to a hydrophobic state. As a result, the surface of the substrate is uniform, and generation of particles can be reduced when the substrate is removed.

Liquid applicators and methods. The liquid applicators include a frame and an applicator head operably coupled to the frame and configured to support a section of an applicator fabric for operable application of a liquid to a substrate. The liquid applicators further include a fabric conveyance system that is operably coupled to the frame and includes a fabric pay-out assembly configured to supply the applicator fabric to the applicator head and a fabric take-up assembly configured to receive the applicator fabric from the applicator head. The liquid applicators further include a liquid delivery system configured to deliver the liquid to the section of the applicator fabric. The methods include delivering the liquid to the section of applicator fabric, engaging the section of applicator fabric with the substrate, and moving the section of the applicator fabric across the substrate to apply the liquid thereto.

An apparatus for supplying a liquid medium to a metering unit comprises a housing in which media channels are arranged. One of the media channels is connected to a fluid reservoir that can be acted on by compressed air.

A method of a method of controlling a volume of material dispensed by a constant pressure adhesive and sealant dispensing system controlled by a controller during shots includes automatically adjusting a proportional valve control setting for an orifice size of a controlled pressure regulator. An orifice size control pressure corresponding to the proportional valve control setting is applied to an orifice size control inlet of the controlled pressure regulator. A volume of the material dispensed during each shot is monitored and when the volume of material dispensed during each shot of a predetermined number of successive shots is outside a target range, the proportional valve control setting is automatically adjusted by the controller.
