Abstract

The invention relates to a method for controlling a pump system and to a pump system (34) having a pump unit (44) for dispensing multi-component material under pressure by means of a spray gun, the pump unit comprising a pump device (12), a mixer (13) and a spray gun (14), the pump device having at least two pumps (16, 17) for pumping component material and associated liquid tanks (18, 19) for storing component material, the pump device having an operating means (23) by means of which the pump device is controlled, wherein the pump unit comprises at least one other pump device (35), the pump system having a control device (24), the control device and the operating means (23, 40) together forming a control unit (41), the pump unit being controlled by means of the control unit.

Claims

1. A method for controlling a pump system (10, 34, 45) having a pump unit (11, 44, 46) for dispensing multi-component material under pressure by a spray gun, the pump unit comprising a pump device (12, 35), a mixer (13, 47) and a spray gun (14, 48), the pump device having at least two pumps (16, 17, 36, 37) for pumping component material and associated liquid tanks (18, 19, 38, 39) for storing component material, the pump device having means for operating (23, 40, 51) by which the pump device is controlled,

characterized in that

the pump unit has at least one other pump device (12, 35), the pump system having a control device (24, 52), the control device and the means for operating together forming a control unit (25, 41), the pump unit being controlled by the control unit;

and

the control device (24, 52) has an extending regulating, controlling and/or functional range compared to the controller (23, 40, 51).

2. The method according to claim 1,

characterized in that

the control device (24, 52) is arranged at a distance from the pump unit (11, 44, 46), data being exchanged between the control device and the operating means (23, 40, 51).

3. The method according to claim 1,

characterized in that

the pumps (16, 17, 36, 37) are controlled independently from one another by the control device (24, 52).

4. The method according to claim 1,

characterized in that

data is exchanged with an external network (31) by the control device (24, 52).

5. The method according to claim 1,

characterized in that

the operating means (23, 40, 51) transmits environmental parameters, operating states, operating parameters and/or error messages of the pump device (12, 35) to the control device (24, 52), the control device processing the environmental parameters, operating states, operating parameters and/or error messages.

6. The method according to claim 1,

characterized in that

the control device (24, 52) initiates and carries out a purging of pumps (16, 17, 36, 37), mixers (13, 47) and/or spray guns (14, 48) in parallel.

7. The method according to claim 1,

characterized in that

pumps (16, 17, 36, 37), mixers (13, 47) and/or spray guns (14, 48) not used during a period of time are purged automatically.

8. The method according to claim 1,

characterized in that

data is exchanged with a robot by means of the control device (24, 52).

9. A pump system (10, 34, 45) having a pump unit (11, 44, 46) for dispensing multi-component material under pressure by a spray gun, the pump unit comprising a pump device (12, 35), a mixer (13, 47) and a spray gun (14, 48), the pump device having at least two pumps (16, 17, 36, 37) for pumping component material and associated liquid tanks (18, 19, 38, 39) for storing component material, the pump device having a controller (23, 40, 51) for controlling the pump device,

characterized in that
