Abstract
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.
Claims16
A powder-dispensing device in the form of a dense phase powder pump or a powder injector for conveying coating powder from a powder reservoir to a powder-spraying device, wherein the powder-dispensing device comprises:
- a control device integrated into the powder-dispensing device and being configured to set at least one parameter which is characteristic in respect of a spray coating process effected with the powder-spraying device;
- wherein the control device is further configured to perform spray coating processes, wherein the control device comprises a storage device having a plurality of spray coating programs, wherein each spray coating program has at least one respective adjustable parameter, wherein the control device comprises at least one manually operable parameter adjuster element for setting a parameter target value for the at least one adjustable parameter, and wherein the control device comprises a visual display unit for automatically displaying the at least one set parameter target value;
- wherein the control device is further designed to set at least one parameter which is characteristic in respect of a powder conveyance effected with the powder-dispensing device;
- and
- wherein the at least one manually operable parameter adjuster element is further configured for setting a parameter target value for the at least one characteristic parameter of the powder conveyance effected with the powder-dispensing device.
A powder-dispensing device in the form of a dense phase powder pump or a powder injector for conveying coating powder from a powder reservoir to a powder-spraying device, wherein the powder-dispensing device comprises:
- a control device immediately physically connected to the powder-dispensing device being configured to set at least one parameter which is characteristic in respect of a spray coating process effected with the powder-spraying device;
- wherein the control device is further configured to perform spray coating processes, wherein the control device comprises a storage device having a plurality of spray coating programs, wherein each spray coating program has at least one respective adjustable parameter, wherein the control device comprises at least one manually operable parameter adjuster element for setting a parameter target value for the at least one adjustable parameter, and wherein the control device comprises a visual display unit for automatically displaying the at least one set parameter target value;
- wherein the powder-dispensing device is designed in the form of a dense phase powder pump having at least one feed chamber provided with a powder intake valve and a powder outlet valve, and wherein the control device is designed to generate control signals in order to repeatedly implement the following a) to d) operating cycle:
- a) generating a negative pressure in the feed chamber to suck coating powder in the feed chamber through the open powder intake valve while the powder outlet valve is closed;
- b) closing the powder intake valve and opening the powder outlet valve;
- c) introducing compressed gas into the feed chamber to dispense the coating powder out of the feed chamber through the open powder outlet valve while the powder intake valve is closed;
- and
- d) closing the powder outlet valve and opening the powder intake valve, and
- wherein the control device is further designed to produce a control signal at cycle step a) or when switching from cycle step d) to cycle step a) in order to generate the negative pressure in the feed chamber.
A powder-dispensing device in the form of a dense phase powder pump or a powder injector for conveying coating powder from a powder reservoir to a powder-spraying device, wherein the powder-dispensing device comprises:
- a control device integrated into or connected to the powder-dispensing device and being configured to set at least one parameter which is characteristic in respect of a spray coating process effected with the powder-spraying device;
- wherein the control device is further configured to perform spray coating processes, wherein the control device comprises a storage device having a plurality of spray coating programs, wherein each spray coating program has at least one respective adjustable parameter, wherein the control device comprises at least one manually operable parameter adjuster element for setting a parameter target value for the at least one adjustable parameter, and wherein the control device comprises a visual display unit for automatically displaying the at least one set parameter target value;
- wherein the control device is further designed to set at least one parameter which is characteristic in respect of a powder conveyance effected with the powder-dispensing device;
- and
- wherein the at least one manually operable parameter adjuster element is further configured for setting a parameter target value for the at least one characteristic parameter of the powder conveyance effected with the powder-dispensing device.
