Definitions

• the invention relates to an ink supply adapter for a device for dosing ink into an ink fountain of a printing press, with a holder that is open at the front or on the side for receiving a ink cartridge and a compressed air connection in the holder for ink delivery.
• Such a metering device is known, for example, from US 2003/0110967 A1.
• the ink is usually supplied via dye cartridges, which can be exchangeably inserted into a space provided in the cartridge holder.
• Color cartridges are used in particular when only relatively small quantities of ink are to be used for a specific printing process or when frequent color changes are to be provided. The use of color cartridges requires monitoring of the fill level and changing the cartridges is time-consuming.
• a paint dispensing insert for a paint supply system of a different kind, which can be inserted from above in a sleeve-shaped holder that can only be opened from above, and which has an essentially cylindrical outline on the inside of the inside of the holder has a sleeve-shaped holder adapted valve housing, which can be placed on the bottom of the holder and penetrates a concentric outlet opening in the bottom with an outlet pipe directed downwards.
• the paint delivery insert comprises a connecting pipe, which extends from the valve housing and penetrates an upper cover of the sleeve-shaped holder, for connection to a hose line which extends from a paint container outside the holder.
• An ink delivery valve present in the ink delivery insert can be actuated via a separate compressed air connection.
• the object of the present invention is to provide an ink supply adapter which can be easily exchanged for a color cartridge, in which the same compressed air supply, which is present anyway for expelling the ink from a color cartridge, is used for the color metering when connected to a larger ink supply.
• the ink supply adapter not only in the cartridge receiving space of the front open holder of a metering device of the type mentioned above, e.g. can be used essentially transversely to its longitudinal axis, but also a compressed air inlet for the connection to the compressed air connection of the holder, which is otherwise used for the ink delivery from a color cartridge, an ink supply inlet, preferably into the valve housing and a device which can be controlled by means of the compressed air from the compressed air connection of the holder Paint delivery valve has.
• the ink supply adapter has an adapter housing, adapted in diameter and height to the dimensions of the ink cartridge receiving space of the holder for an ink cartridge, for receiving the ink discharge valve, so that the ink supply adapter is simply exchanged from the side for an ink cartridge and only the connection to the ink supply must be established, while the connection to the compressed air supply, such as when a color cartridge is inserted, is established automatically.
• the adapter housing has at least two spaced apart, for. B. circular end plates.
• the lower end plate forms the base in the holder, while the spacers, which can be designed as rods, leave free access to the ink cartridge receiving space and the valve housing located in the adapter housing, so that the ink supply adapter is in place, for example via a connecting hose can easily be connected to the paint supply.
• a preferably flexible connection is provided between the compressed air inlet in the end plate facing the compressed air connection of the holder and an end-side or side compressed air inlet of the valve housing, so that different types of paint discharge valves with correspondingly different valve housings can be accommodated in the adapter housing.
• ink supply inlet opens laterally into the valve housing in order to be easily accessible.
• the single figure of the drawing illustrates, in an oblique view, an ink supply adapter embodying the invention, inserted into a device for metering ink into a ink fountain of a printing press, which device is known per se with a holder that is open in its peripheral wall at the front or on the side for holding a color cartridge.
• the device shown in the drawing for dosing ink into an ink fountain of a printing press has a holder H for receiving a (not shown) ink cartridge.
• the holder H is open in its circumferential wall to the front and to the side over the entire height of the color cartridge that is normally to be used, so that the latter can be inserted into the cartridge receiving space 4 from the front or from the side, and automatically a compressed air connection between the one above and the cartridge receiving space 4 located part H 'of the holder H provided compressed air connection. Because of the compressed air flowing into the conventionally provided ink cartridge, the ink is emitted from this ink cartridge to an ink discharge opening in the part H "of the holder H located below the cartridge receiving space 4.
• an ink supply adapter 13 of a special type is inserted into the cartridge receiving space 4 instead of an ink cartridge.
• the height and diameter of the ink supply adapter 13 are adapted to the dimensions of the cartridge receiving space 4 which is open at the front and on the side, so that when the ink supply adapter 13 is inserted in the direction transverse to its longitudinal axis, a compressed air inlet 1 located in an upper end plate 7 of an adapter housing 5 is directly in Flow connection occurs with the compressed air outlet provided in the upper part H 'of the holder H anyway for the use of the device with color cartridges.
• a flexible connection 8, which is formed, for example, by a hose connection, adjoins the compressed air inlet 1 and leads to a compressed air inlet 9 of a valve housing 10 accommodated in the adapter housing 5.
• the compressed air inlet 9 can open into the valve housing 10 from the top or from the side.
• a paint delivery valve 3 which, with a corresponding pressurized air supply via the connection 8, can open downwards into a through hole (not shown) in a lower end plate 7 'of the adapter housing 5, which in turn can open into the (also not visible) Paint discharge opening of the lower part H "of the holder H opens.
• the end plates 7, 7 ' are held in the required distance for the fit of the adapter housing 5 in the cartridge receiving space 4 via spacers 6 designed as threaded rods, so that an adaptation to other spatial conditions and dimensions can be provided by using spacers 6 of different lengths.
• the rod connection also ensures easy access to the paint supply inlet 2, which is provided with a threaded connection for a hose line 11, in the peripheral wall of the valve housing 10 of the paint discharge valve 3.
• the hose line 11 is in flow connection with a paint container, from which color is to be delivered.
• the hose line 11 only has to be connected to the ink supply inlet 2 of the valve housing 10 from the side. Due to the arrangement of the compressed air inlet 1 in the upper end plate 7 of the paint supply adapter 13 and the connection 8 integrated in the paint supply adapter 13, no additional air hose is required to actuate the paint discharge valve 3. Even when switching back to An air hose does not have to be uncoupled or connected to a color cartridge.
