Definitions
- the present invention relates to an arrangement for dispensing highly viscous media, as is known from DE 44 31 427 AI in connection with the use for food and washing pastes, that is to say highly sensitive media in terms of purity and hygienic cleanliness.
- Printing inks are usually either manually filled into a color box, this is in slightly less viscous newspaper inks, or they are filled with a very high-viscosity offset ink.
- offset inks there is also the option of automatically feeding these inks from a tubular bag (compare INKCLIPS from Gebruder Schmidt printing inks) or a cartridge up to 2 kg of printing inks to a color box. From 30 1 there is also the option of pressing and pumping out offset inks using a printing plate. Gravure inks, heatset inks and coldset inks are automatically fed to a color box from tanks or 445 1- or 1000 1-containers.
- the basic idea of the present invention is therefore primarily to provide the known arrangement for dispensing highly viscous media for use in supplying printing presses.
- Fig. 2 shows an embodiment with respect to the elastic plate for the space between the piston and the container.
- FIG 1 shows an overall representation for dispensing printing ink.
- the printing ink to be dispensed is located in a circular cylindrical plastic container 1 which has a screw socket 2 in the center of one end face.
- This plastic container 1 is inserted into a pressure vessel 3, which is formed by a piston / cylinder unit.
- the pressure vessel 3 has a cylinder base 4, against which - in the rest or starting position - a working piston 6 equipped with a filler 5 - possibly with a play W2 - bears.
- This working piston 6 moves axially (see arrow A) in a cylinder tube 7 which is tightly closed on the second end face by means of a pivotable (see reference number 8) and in particular locked by a screw cap 8 1 cylinder cover 9.
- the plastic container 1 is now inserted in the filled state in the cylinder space between the working piston 6 and the cylinder cover 9 and guided through its screw connection 2 through the cylinder cover 9 to the outside in such a way that between the plastic container 1 with the screw connection 2 and one designed as a hose or tube Demand line 10 a pressure-tight connection can be made.
- the plastic container 1 can now be squeezed together with its contents by axial movement of the working piston 6.
- M2 / M3 ⁇ 1.5; M2 mean the play between the diameter of the cylinder tube 7 and the working piston 6 and M3 the wall thickness of the plastic container 1. If this relationship is observed, there is a risk of the plastic container getting caught between the working piston 6 and the cylinder tube 7 minimized.
- said free space is formed in that an elastic plate 11, 12, for example a foam plate, is placed on each of the cylinder cover 9 and the working piston 6, the outer diameter of which is smaller than the outer diameter of the plastic container 1.
- an elastic plate 11, 12, for example a foam plate is placed on each of the cylinder cover 9 and the working piston 6, the outer diameter of which is smaller than the outer diameter of the plastic container 1.
- a connection 13 for a pressure medium is provided in the cylinder base 4, which is connected via a pressure switch 14 to a pressure generator (compressors 15, 16).
- a pressure generator compressors 15, 16
- the working piston 6 is connected to an axially outwardly projecting piston rod 17 which carries a cam disk 18 at the end.
- Switches for example microswitches, are actuated via this cam disk 18, one (19) of which corresponds to the rest (or initial) position and the second (20) of which corresponds to the entire arrangement after the maximum stroke of the working piston 6 has been reached, i.e. when the plastic container 1 is empty, switches off.
- a third microswitch 21 is provided, which is activated, for example, when the working piston 6 has squeezed the plastic container 1 to such an extent that only (approximately) 10 residual quantities are still present.
- This third microswitch 21 can for example be connected to a warning horn 22 and / or a warning lamp 23.
- the printing ink printed out of the plastic container 1 is squeezed into the delivery line 10, which is pressure-tightly connected to the screw socket 2 of the plastic container 1. is bound, in such a way that the connecting element of the delivery line 10 is completely immersed in the screw socket 2.
- a plug-in coupling is preferably provided for the connection between the delivery line 10 and the screw connector 2, the delivery line 10 and plastic container 1 having coupling elements that are complementary to one another.
- the printing ink is fed to an ink fountain (not shown in the drawing) (arrow X) with the aid of a pinch valve 30 placed on the delivery line 10, which regulates the flow of the printing ink.
- a sensor element 31 is assigned to the ink fountain, which monitors the amount of ink in the ink fountain and generates corresponding control signals when the specified target values are exceeded or undershot.
- the printing ink is in constant constant pressure in the delivery line 10 and is ultimately supplied to the ink fountain by actuating the pinch valve 30.
- the arrangement is activated via the pressure switch 14.
- This pressure switch 14 has three switching points, via which in turn three microswitches 141, 142, 143 are actuated.
- the microswitch 141 corresponds to the minimum working pressure P1 of the arrangement, while the other two microswitches 142 and 143 serve as an off switch for the two compressors 15 and 16 acting as pressure generators.
- connection 13 for the working piston 6 is also coupled to a pressure relief valve 44, which in turn is actuated via a further switch 45 and is required when, for example, the plastic container 1 is to be replaced.
- FIG. 2 shows an exemplary embodiment relating to the verification of the free spaces for inserting the bellows 50 when the bellows are completely closed.
- Fig. 2 shows the cylinder tube 7 of the piston / cylinder unit along which the working piston 6 is moved.
- an annular seal 65 is inserted.
- the game between the working piston 6 and the cylinder tube 7 corresponds to the indicated dimension M2 and this game must obey the relationship M2 / M3 ⁇ 1.5 for the proper function of the entire arrangement relative to the wall thickness M3 of the plastic container 1.
- the space for storing the bellows is formed by an elastic plate 11, which leaves a defined annular bead on the circumference.
- the folds can be inserted unhindered in this free space, a support ring 66 being able to be inserted on the circumferential side of the working piston 6 if necessary.
- a wiper nose 111 which grinds on the cylinder tube 7 is provided, leading to the direction of movement A of the piston 6.
- This stripper 111 prevents the plastic container 1 from being drawn in between the piston and the cylinder wall 7 and is necessary because when the highly viscous printing ink is pressed out, pressures of up to 2.5 bar are necessary and the flow behavior of the printing ink is very tenacious.
- a plastic container is changed by switching off the pressure on the piston, the closure coupling is separated from the hose connection valve, a filled plastic container is inserted into the cylinder space, the closure coupling is connected to the new hose connection valve and the piston is pressurized again .
- the pinch valve is opened and the pressure on the piston is switched off.
- the plastic container is removed from the cylinder and the hose is removed from the support hose or from the gutter and the hose crimp. til pulled and set aside as a unit. A new plastic container with a clean hose is placed in the system.
- the hose with the closure coupling and the hose connection valve is freed of printing ink in a flow device and can be used again.
- the entire system consisting of the piston / cylinder unit, the locking coupling and the hose connection valve, the hose pinch valve as well as the sensor and the control system, can be designed as a plug-in system (electricity and compressed air connection) stationary or mobile.
