Definitions
- the invention relates to a coating system for coating objects, in particular vehicle bodies, with frequently changing color material according to the preamble of claim 1.
- Known generic coating systems each contain a storage device in which color materials with different color tones are provided. Furthermore, there is a transport device for the different color materials to at least one coating station, where objects passing through in cycles are at least partially coated. This coating station contains application devices, in particular spraying elements for applying the coating to the object currently present.
- such coating systems each include a control device for a color change, which cooperates with the storage device, the transport device and the application device and with control elements in such a way that when a certain object is present in the coating station, the desired and assigned one ⁇ nete color material is available on the application device.
- the storage device consists of large paint containers.
- the transport device comprises a plurality of ring lines and stub lines, in which the color material is transported and pumped fluently.
- the paint is applied by means of a spray organ, which can be connected via a paint-carrying line and a number of controllable valves either to one of several different paint lines to the individual paint containers or to a detergent line.
- a spray organ which can be connected via a paint-carrying line and a number of controllable valves either to one of several different paint lines to the individual paint containers or to a detergent line.
- the paint-carrying line and the spray organ are freed from residues of the paint previously used. Large amounts of a detergent / paint mixture are generated and must be disposed of. In addition to the considerable loss of color material associated with this, a considerable environmental impact must also be accepted.
- DE 39 27 880 AI also suggests a costly possibility of recovering paint residues from stub lines and hoses by emptying them into those containers from which the paint had previously been removed.
- DE 41 33 840 AI a return of color residues during the color change is possible by providing a number of collecting vessels corresponding to the number of different color materials to be processed. These receptacles are each connected to the return line by the control device in the event of a color change, so that only a mixture of a specific color with the detergent is collected in each receptacle. This mixture can be the original color be added again. The environmental impact and loss of color can thus be reduced, but complex rinsing and cleaning of considerable line lengths is nevertheless necessary in the case of a color change and is associated with a high expenditure of time, a quality risk and the risk of material being discarded.
- the object of the invention is to further develop a coating system of the generic type in such a way that coatings with a large number of color materials of different colors are possible with a low environmental impact.
- the storage device consists of a cartridge sorting and shelf storage in which a large number of color cartridges are stored both with the same and with different color material.
- the storage locations of the individual color cartridges can be determined by the control unit in connection with the color tone of the color material contained in each case and / or a color quantity of the color material contained in each case.
- a corresponding color cartridge can be output at an output of the cartridge sorting and racking store via a control signal, which contains coded information about the color material and / or quantity of paint required in each case on the application device for a coating.
- the transport device is a cartridge transport device with which ink cartridges output at the outlet of the cartridge sorting shelf store can be transported to a docking station in a feed branch in the closed state.
- This docking station is connected upstream of an application device, with docked color cartridges being opened for dispensing the color material.
- Color materials with an almost arbitrary number of colors in the cartridge clock frequency can be made available on the application devices. Rinsing the cartridge transport paths is obviously not necessary. Rinsing and cleaning devices, such as were previously required for at least some of the color material lines, are now only limited to the application device. Loss of time and media losses are reduced and an enormous reduction in solvents is possible with a positive impact on environmental protection, occupational safety and fire protection. The flushing medium consumption at the application device can be minimized.
- the cartridge system can also be combined with conventional ink material supply systems.
- the ink cartridges with ink material in processing viscosity are advantageously supplied by the paint supplier, a circulation system with a cartridge or residual ink material disposal and refilling being able to be implemented by the paint supplier. It is also possible to calculate the exact material consumption based on the amount of ink actually used, based on each color.
- the cartridge distribution into and out of the cartridge sorting and storage system can be controlled in a simple manner using known measures in connection with electronic data processing such that each color cartridge arrives at an assigned object, in particular a vehicle body, at the right time.
- known bar code controls can be used with regard to relevant data, in particular also expiration dates of the color material.
- the docking of the color cartridges in the docking station to the application device can be automated with common measures, as can a metered amount of ink.
- the coating system can be fully automated, so that only a small amount of personnel is required.
- empty ink cartridges are correspondingly returned to the same (or possibly a different) cartridge sorting and racking storage via a return branch, thereby forming a ring line system for the ink cartridges.
- the coating system can be easily loaded with color-filled color cartridges and empty color cartridges can be removed centrally.
- the transport of the ink cartridges is air-assisted in a piping system in the manner of a pneumatic tube proposed.
- a pneumatic tube proposed.
- pneumatic control devices known and proven per se can be used.
- the color cartridges are correspondingly cylindrical, with outer sliding and guide rings. Such pipelines can easily be bent over long distances.
- a cylinder-piston arrangement is contained in the color cartridges.
- the plunger When the color cartridge is full, the plunger is in one end position and the other side of the cartridge is closed. In this state, a color cartridge is delivered, stored and transported to the docking device. When it arrives there and is docked, the cartridge docking side is opened and moved by moving the piston bens the ink cartridge forcibly emptied.
- This emptying can advantageously be time-controlled and / or pressure-controlled for a defined emptying and application of the color material.
- the front of the cartridge can have a tear-open or pierceable cover as a closure.
- Claim 7 alternatively proposes a closure in the manner of a spring-loaded valve. In the docking station, a valve tappet then only needs to be inserted somewhat into the color cartridge for the opening.
- Claim 8 also claims a transverse sliding device for a color cartridge in the docking station, as a result of which the piston rear side of a color cartridge is accessible for attachment to a push rod for cartridge emptying. According to claim 9, a next color cartridge can already be kept in a waiting position in the docking station.
- the loading and emptying (empty color cartridges) of the cartridge sorting and shelf storage can take place automatically at time intervals via storage inputs and storage outputs and / or according to claim 11 via exchangeable magazines which contain a plurality of color cartridges.
- a code in particular a barcode with all relevant filler data, should be attached to each color cartridge according to claim 12.
- At least one shaking device for mixing the color material in a cartridge is also provided in the course of the cartridge provision and / or the cartridge transport. Exemplary embodiments of the invention are explained in more detail with reference to a drawing.
