Definitions
- the invention relates to a device for prefiltering the fountain solution in a printing press with at least one printing unit.
- a pre-filter device is provided, which is assigned to each printing unit of a printing press.
- This pre-filter device is arranged in a separate housing, which is usually arranged outside the printing press.
- Such separate apparatuses not only leave a negative impression visually, but also hinder working on the printing press.
- the invention has for its object to propose a device which avoids these disadvantages of the prior art.
- a pre-filter housing is provided, in which a pre-filter is arranged, and in that the pre-filter housing is integrated in the printing unit of the printing press.
- a further development of the device according to the invention provides that at least part of a housing wall of the prefilter housing is designed as a door. It is particularly advantageous that this door is also the door on the operating side of the printing unit. This construction ensures that the prefilter is easily accessible from the operator side, for example. It is easy to change the filter mats.
- the frame of the prefilter housing be provided with elastic sealing material is provided.
- this sealing material is foam.
- a collecting container for the dampening water is located under the filter housing in which the pre-filter is arranged. This collecting container is dimensioned so that the dampening water collects here when the printing machine is switched off.
- a further development of the device according to the invention provides channels in which the hoses for returning the dampening water run from a dampening unit to the prefilter housing.
- the hoses do not hinder any further elements of the printing unit.
- the channels are designed in such a way that there are no short bends or kinks in the hose guide. Since deposits are preferred at kinks, the smooth hose routing largely prevents contamination - and in extreme cases clogging of the hoses.
- the top of the prefilter housing is designed as a trough. This pan is used to collect oil.
- This combination of drip pan and prefilter housing is particularly simple and inexpensive.
- a line leads the fountain solution from the pre-filters in the printing units to a main filter.
- a main filter has become known, for example, from utility model DE-U1 91 01 888.
- a device for displaying the dampening solution level is arranged in the prefilter.
- the dampening solution level is checked using a float switch.
- An increase in the dampening solution level is usually an indication that the filter has become clogged due to impurities and that there is a dampening solution accumulation in the area of the pre-filter. Since overflowing dampening solution can also be briefly cleaned by the main filter, it is sufficient for the float switch to activate a warning indicator. Since the main filter can temporarily take over the task of the pre-filter, the filter mats can be replaced while the printing machine is in operation.
- Fig. 1 is a section through a printing unit 1 of a web-fed rotary printing press, not shown separately shown.
- this printing unit 1 the device according to the invention for pre-filtering the fountain solution is integrated.
- An upper dampening unit 2 and a lower dampening unit 3 are assigned to the pressure cylinders 17.
- the return of the dampening water from the dampening units 2, 3 takes place via hoses 4, which are guided in channels 5.
- the dampening water to be cleaned passes through the hoses 4 into a pre-filter 6 in which filter mats 8 are arranged.
- the pre-filter 6 is arranged in the filter housing 7. This filter housing is closed by a door 12 on the operating side of the printing unit 1.
- a collecting container 9 which is at least dimensioned such that it can hold the dampening water flowing out of the dampening units 2, 3 and the pre-filter 6 when the machine stops.
- the collecting container 9 is connected to the main filter 19 via a collecting line 10.
- a level indicator 20 for example a float switch, is arranged in the pre-filter 6 and activates a warning display when a certain level is exceeded.
- Fig. 2 shows a longitudinal section through the device according to the invention for pre-filtering the fountain solution.
- the device according to the invention is arranged in the lower region of the printing unit 1.
- the dampening water is fed from the upper and lower dampening units 2, 3 into the prefilter 6 via hoses 4. These hoses 4 are guided in channels 5.
- the prefilter 6, in which the filter mats 8 are arranged, is located in the filter housing 7. Below the prefilter 6, there is the collecting container 9. From this collecting container 9, the dampening solution is transferred via a Line 10 passed to the main filter 19, not shown.
- the prefilter housing 7 is closed by a door 12.
- This door 12 is also the door on the operating side of the printing unit 1.
- the frame of the pre-filter housing 7, which serves to accommodate the door 12, is provided with elastic sealing material 13.
- This elastic sealing material 13 is, for example, foam.
- webs are additionally provided on the frame of the door, which are pressed into the sealing material when the door is closed. This results in an effective sealing of the areas that carry the dampening solution.
- the top 15 of the prefilter housing 7 is advantageously designed as a trough 18.
- the top 15 of the prefilter housing 7 is at the same time suitable for collecting oil from central lubrication escaping from bearings. Since the upper side 15 of the prefilter housing 7 thus fulfills a double function, this design is particularly cost-effective.
- the oil is discharged from the trough 17 via an outlet connection 16.
- Fig. 3 shows a cross section through the device according to the invention for prefiltering the fountain solution.
- the prefilter 6 is arranged in the upper region of the filter housing 7;
- the collecting container 9 is located in the lower area. Sealing material 13 and webs 14 engaging in this sealing material, which are located on the inside of the door 12, isolate the areas that carry the dampening solution.
- dampening agent-carrying hoses 4 are guided through the side wall 11 of the printing unit 1 and then through channels 5, so that they do not impede any control elements of the printing unit 1.
