- the present invention relates to a method for applying a Liquid mixture of a first liquid and at least one second liquid a web-shaped printing material according to the preamble of claim 8.
- a paper web is usually taken from a supply roll handled and passed through a number of printing units, which the web mostly Print on both sides and in multiple colors using the wet offset process.
- the fresh printing ink is passed through a hot air dryer, in which Evaporate water and volatile solvents from the ink. Then the train led to hardening of the liquid paint over cooling rolls of a cooling roll stand, which be flushed out by a cooling medium.
- the finished Print products led the web to a folder, which the web in different Can fold and cut configurations. Often the finished products are one Mailroom fed.
- silicone oil emulsion applied to the dried web.
- the water content of the emulsion also leads to a desired rewetting of the Web after the drying process.
- the device has a buffer and Mixing container on a supply line with a storage container for Silicone oil concentrate is in connection.
- the buffer and mixing tank serves among other things for buffering silicone oil emulsion, since the storage container before reaching a lowest Level is exchanged for another storage container, so that for one supply of silicone oil concentrate is not possible for a certain period of the exchange.
- the Buffer and mixing tank is also connected to a water supply, so that Containers not only for buffering but also for mixing a desired one Silicone oil emulsion can be used.
- the mixture produced is over a Heat exchanger for heating the mixture to a respective tub of a respective one Application roller directed, from which tub the mixture is scooped by means of the application roller and transferred to a paper web.
- a control unit is connected to an upper and a lower sensor, which monitor the fill level of the buffer and mixing tank. When the fill level reaches the level of the lower sensor, the control unit opens a valve in the water supply until the Level reaches the level of the upper sensor, the control unit then closes the valve again. At the same time, a desired amount of silicone oil concentrate is made from the Conveyed storage container into the buffer and mixing container, so that a silicone oil emulsion in desired mixing ratio arises.
- the known device has some disadvantages. For example, it won't Silicone oil concentrate but silicone oil emulsion of a desired mixing ratio buffered. It can happen that the filling level of the buffer and mixing container lowest level reached, with a refill of silicone oil concentrate not possible immediately is because the reservoir can also have reached its lowest level at the same time. Furthermore, the buffer and mixing tank must be very large because the Emulsion is consumed much faster than the concentrate.
- the known device also does not allow the application of silicone oil emulsion different mixing ratio on the two sides of the paper web. For this the known device would have to be used separately on both sides, so that for a buffer vessel would be available on both sides.
- the mixing container and the buffer container represents two separate containers or vessels, each a room have in which the liquid in question is taken up.
- the containers can spatially separated from one another or arranged directly next to each other or adjacent. It can also be provided that the two containers form a common vessel, which is divided into at least one partition into the two containers.
- the separation or separation of the mixing vessel and the buffer vessel according to the invention advantageously allows the supply of the application device with Ensure fluid mixing uninterrupted.
- the installation space of the buffer tank can advantageously be reduced, as can the installation space of the mixing container.
- the device can be a supply line from the buffer tank to the Have mixing container with a valve, which by a control and / or Control device is operated such that a continuous or quasi-continuous or intermittent flow of the first liquid is generated.
- the percentage composition of the liquid mixture be variable, d. H. can be influenced, due to the small size of the vessels very short response time can be achieved, so that, for example, even during the An adjustment to changed parameters of the current print job can be made possible during operation.
- control and / or regulating device can have a respective valve in one Supply line from the supply device for the second liquid to a first and operate a second mixing container so that a continuous or quasi-continuous or intermittent flow of the second liquid is generated.
- the supply of the second liquid which is preferably the larger percentage of the liquid mixture is advantageously done by a supply facility directly to the mixing tank, d. H. without buffering.
- the supply facility has the Property of being able to supply the second liquid almost endlessly, for example from one Supply network.
- the application device is a float element or a Filling level sensor having the control and / or regulating device for signaling and / or Data transmission, especially the level, is connected.
- the container of the application device is in the form of a tub trained and an applicator scoops the liquid mixture from the tub and transfers them to the substrate.
- the application roller can be driven by a motor, which in particular by the Control and / or regulating device is controlled and / or regulated such that the speed the application roller is changeable.
- the mixing container has a smaller one Capacity as the buffer tank.
- the capacity of the mixing container can, for example, in about 1 liter and the capacity of the buffer tank can be Example in about 10 liters.
- a control and / or regulating device can actuate at least one valve in such a way that that a continuous or quasi-continuous or intermittent flow of the first Liquid and / or the second liquid to the mixing container is generated.
- a method for dampening a printing material web wherein a water-silicone oil concentrate mixture is applied to the web, characterized in that the water content and the silicone oil concentrate content - e.g. B. the web speed and / or the web width can be adjusted - can be selected separately.
- Figure 1 shows an inventive device for applying a liquid mixture a first and at least a second liquid on a web-shaped printing material.
- a web 24, in particular a printing web 24, for example made of paper, is after unwinding and printing in printing units by a hot air dryer 84 and then for cooling via cooling rollers flushed with coolant 86, 88 and 90 in Direction of movement 92 performed.
- the web 24 is in the dryer 84 by the hot air, which solvent the ink to evaporate, moisture 94 is also removed, so that it may be necessary then at least partially rewet the web 24.
- the cooling of the web 24 results in the ink curing, but it can nevertheless for depositing ink on guide rollers or surfaces in subsequent ones Machine parts, for example in the folder, come. This dropping of paint can counteract with the application of silicone oil on the web 24.
- the first liquid 1, in this case silicone oil concentrate 1, is in a storage container 2 added.
- This container 2 can, for example, a sufficient amount of Take up silicone oil concentrate for at least one complete print job, so that one Replacing the container 2 only very rarely, for example only after several print jobs, becomes necessary.
- the container can be designed as a barrel, for example. It is beneficial to store the silicone oil concentrate instead of a silicone oil mixture, since smaller containers can be used.
- the container 2 stands with a buffer container 4 for the first liquid 1, hereinafter by way of example but not specifying as silicone oil concentrate 1, via a Supply line 6 in connection.
- the line 6 has a pump 8, which the Silicone oil concentrate 1 from the storage container 2 to the buffer container 4 in the desired Crowd encourages.

- the percentage composition of the liquid mixture 18 correspond to the Pressure requirements because the mixing tank - due to the continuous, quasi-continuous or intermittent inflow of water and silicone oil concentrate - with a very small volume or capacity, for example about 1 liter, in Compared to the buffer tank, for example about 10 liters, can be equipped.
- the two mixing containers 12, 14 are, for example, always in operation Substantially filled, since the controller 42 is dependent on the signal of the Float element 54 substantially continuously refilling the Mixing container 12, 14 and the tubs 44, 45 controls.
- the float element 52 can do that when it drops Actuate or trigger the opening of the valve 36 directly, so that the controller 42 additionally only ensures the appropriate flow of silicone oil concentrate, so that the desired mixture is created.
- the two mixing containers 12, 14 can be constructed in such a way that solely on the basis of their Design sufficient mixing of the two liquids takes place in the Example both liquids are fed to the bottom of the container and mix, during the drain and thus the supply of the tubs 44, 45 by means of an overflow happens. However, it can also be the case that in at least one of the two Mixing container 12, 14 and a mixing element, for example a stirrer, is provided.
- a mixing element for example a stirrer
- the flow of the liquid mixture to the tubs 44, 45 may be due to gravity or by means of pumps not shown.
- the invention Device also at least one tempering filing (or one for each side of the web) can have for the liquid mixture 18. Conventional are available for this Heat exchangers or heating devices.
- the inflow of silicone oil concentrate 1 from the reservoir 2 also increases the buffer container 4 can be essentially continuously (quasi-continuously) by the controller 42 can be controlled and / or regulated, so that advantageously also on the Overflow line 10 can be dispensed with.
- the overflow line 10 and Return of the silicone oil concentrate 1 also a good mixing or Homogenization of the concentrate is guaranteed, so that it can also be advantageous to have a Maintain overflow line 10.
- the controller 42 can also be part of the machine control and for Example in the central control system of the printing press, a dryer with an integrated Cooling roll stand or the cooling roll stand can be integrated, so that on a separate Controller 42 - that is, a computer or processor with memory - at a cost saving can be dispensed with.
