- the small containers are preferably made of stainless steel.
- the closure of the small container can, for example, be formed from a pierceable film.
- the pierceable film can be made of a material that self-seals the enclosed conveyor.
- the small containers wear an identification feature, for example a barcode, which is automatically read before the small container is opened.
- the barcode can preferably also be used to provide application data suitable for the lacquer of the color concerned, for example for controlling the spraying elements.
- the design of the small containers is not subject to any restrictions. It can depend on the type of special paint supply unit. Small container and paint conveyor, as explained above, combine to form a sealing paint supply system that can be handled automatically as a closed system.
- the small containers are, for example, cartridges, cans,
- Bottles or other containers for example between 0.5 and 10 liters in size.
- the small containers can have different shapes, for example they can be cylindrical, cuboid or cubic. They have a closure on one side, which can be in the form of a cover or a film (for example made of metal or plastic). The closure can also be preformed
- Segment of the container surface for example as a stamped window or as a pre-shaped outlet spout.
- the paint supply device preferably has an opening device for the small containers.
- the small containers can therefore be connected to the paint conveying device, for example on the lid defined above, for example by piercing, cutting, pressing in, drilling through, screwing on.
- the opening can point upwards, for example; however, it can also be oriented in a different direction, for example downwards.
- the small container can also be designed to be pressure-resistant, ie the lacquer can then be pressed out of the small container by overpressure with a pressure medium, for example air or an inert gas such as nitrogen. If the small container is not sufficiently pressure-resistant, it is advisable to insert it beforehand into a correspondingly shaped, larger pressure-resistant over-container; this has the advantage that the overcontainer too is easy to seal with a preformed lid in which the conveyor can be or can be integrated. In this case, it is possible to pressurize either only the small container or the entire excess container in order to convey the paint out of the small container. Another possibility is, for example, that the paint is conveyed out of the small container via a pump or suction device.
- a pressure medium for example air or an inert gas such as nitrogen.

- Supplement feed device for one or more small containers and a discharge device for the emptied small containers can be designed, for example, as a conveyor belt or other conventional feed device; the same applies to the discharge device.
- the paint supply unit then consists essentially of a feed device for the
- the opening device and the paint conveying device are preferably combined with one another, for example in the form of a piercing device.
- a piercing device in which the lacquer conveying device is pierced into the small container, is suitable if the sealing cover or the sealing film of a small container can be pierced.
- the small containers are, for example, cartridges containing the paint
- they are connected to a paint conveyor device which is suitable for supplying the required amount of paint to the spraying elements, for example by automatically controlled actuation of the squeezing device of the cartridge, which is opened, for example, by cutting or piercing.
- the small containers can be held in the conveying device for the small containers either directly or in a pressure-resistant excess container by means of a holding device.
- the holding device can act, for example, in a mechanical, pneumatic or magnetic manner.
- the paint conveyor can be used on the exposed side of the held small container. It is possible to insert a puncturing device, a pressing device or a screwing device
- the seal can for example consist of an elastic material such as rubber, Teflon or Viton.
- the conveyor is placed in the small container and positioned so that it is close to or at the lowest point of the container. Thereafter, the paint can be requested from the small container, for example by applying pressure or using a suction pump. It is also possible to design the paint conveying device so that it can be placed sealingly on small containers of different sizes. This promotes flexible use of the paint conveyor.
- the paint supply device is also a device for rinsing the parts coming into contact with the paint. These parts enclose the inside of the piercing device, as well as the necessary pumps or pressure devices. By introducing a rinsing solution, the corresponding stub lines to the spray organs and the latter can also be cleaned. This also applies to an interposed color changer.
- the rinsing device can, for example, be designed such that the paint conveying device is introduced into a container with a rinsing solution after removal from the relevant small container.
- the outer parts of the paint conveying device (in particular a riser pipe) that come into contact with paint are cleaned, and the rinsing solution also gets into the interior of the paint conveying system and the associated other organs by pumping or applying a pressure medium.
- the flushing process takes place with an alternating air / flushing agent flow.
- the flushing device is preferably designed in such a way that lines are provided which guide the flushing liquid into a suitable collecting container during the flushing process. Additional cleaning devices can also be installed which, after the paint conveying device has been removed from the flushing device, remove any remaining external paint contamination.
- the paint conveying device can then be fed to further small containers which contain, for example, paints with other colors.
- Another object of the invention is a method for painting industrially manufactured goods, preferably motor vehicle bodies or individual parts of motor vehicle bodies with series and / or special colors in one of the painting lines for serial painting defined above as according to the invention.
- the small containers are connected via the conveying device described and the spur lines, optionally with the interposition of a color changer, directly to the spraying devices in question, ie it is a closed system.
- the relevant paint supply unit is switched off and the conveyor with the stub lines is rinsed, which is done via the rinsing device of the paint supply unit. Switching off can be done via valves or a color changer.
- About the flushing device of the The spray organs can also be cleaned from the paint supply unit; however, the spraying elements can also be cleaned using rinsing devices which are customary for painting lines for serial painting.
- Another object of the invention also relates to a method for the special painting of individual motor vehicle bodies or individual parts of motor vehicle bodies within a customary painting line for vehicle series painting.
- This method consists in introducing the individual bodies or parts to be painted without being discharged from the usual painting line by means of the usual guide devices into a spray booth C with the spraying elements used for the series painting.
- the ring and supply lines required for series painting are switched off via valves or an automatic color changer and the spraying elements are cleaned using conventional flushing devices.
- the paint supply unit for supplying small amounts of paint is then provided with the amount of small containers required for the individual paint, which contain the desired paint with a special color.
- the small containers are connected directly to the spray elements via the conveying device described and the spur lines, optionally with the interposition of a color changer.
- the paint supply unit integrated in the painting line is switched off and the conveyor with the stub lines is rinsed, which is done via the additional rinsing device of the paint supply unit. In this way, a precisely measurable amount of special lacquer for individual lacquers can be applied, as a result of which unnecessary lacquer consumption and the associated cleaning operations and environmental pollution can be avoided.
- the invention makes it possible to process paints with series and / or special color tones rationally next to one another in a painting line.
