Definitions
- the invention relates to a printing machine liquid supply cabinet according to the preamble of claim 1.
- Fountain solution preparation devices for fountain solution offset printing are off EP 0 602 312 A1 and EP 0 711 661 B1. They are mostly as Device cabinet trained.
- a printing machine cleaning device of this type is from the US 43 44 361 known.
- the known cleaning device contains one Wash cloth transport device through which a wash cloth from a Clean cloth spindle over a pressing device for pressing a Cloth section against the surface to be cleaned on a dirty cloth spindle is transportable.
- a water supply system consists of a Variety of nozzles that can be connected to a tap water network and tap water through nozzles onto a section of washcloth between the Clean cloth spindle and the pressure device on the wash cloth side spray on which the pressure device is also located. This is the from the side of the cloth facing away from the surface to be cleaned.
- the washcloth is on the clean cloth roll in a dry state.
- the damp soaked with detergent Washing cloth very good grease and color of printing press cylinders, especially from a blanket cylinder of an offset printing machine can remove, but is not suitable for removing paper dust from a blanket cylinder or other cylinders of a printing press or directly from the printing web.
- the printing web is usually one Paper web, however, can also be made of other material or material mixtures exist, for example recycled paper and recycled plastic or just contain recycled plastic and other additives, or from one Plastic film or the like exist.
- a wash towel roll in addition to the detergent with water or one Moistening the water solution would make the towel roll very difficult.
- water stored in the washcloth evaporates much faster as a damp detergent contained in the washcloth, especially if the washcloth is installed in the cleaning device and therefore open but is not used for several hours, days or weeks and in dries up this time.
- Paper dust is not only on paper webs, but is also from them also transferred to the cylinders of the printing press and can be there Form paper dust crusts, partly mixed with printing inks and Ink oil.
- the object of the invention is to achieve a structurally simpler one and cheaper way to create an offset press Fountain solution for offset printing and cleaning water feed.
- the cleaning water supply device with a Dampening unit of the printing press combined to from to get this cleaning water.
- the printing press cleaning device does not need its own tap water supply from a house pipe system, but receives the cleaning water on short Paths from that near the cleaning device at the printing press standing fountain water treatment device.
- the cleaning water can from the fresh water supply line of the fountain water treatment device are removed, either before or after, if necessary, in the Fresh water supply line included descaler for descaling the Water.
- Another option is to remove the cleaning water from a storage container, which is in or outside the Cabinet can stand.
- the cleaning water can Fountain water of the fountain water treatment device.
- This has the additional advantage that it is a "reuse" of the Dampening water.
- the fountain solution is usually from Fountain solution tank of the fountain solution treatment unit to one Dampening well of a printing unit conveyed where a part on the cylinder or rollers of the printing unit is transferred and another part in the Fountain solution tank of the fountain solution treatment unit back is recirculated and filtered. Nevertheless, it also arrives from the printing unit small amount of paper dust and other dirt particles, for example Paint particles, in the fountain solution tank. Because of this, and also because of the natural aging of the fountain solution, the fountain solution must from time to time Time to be cleaned or replaced. By "reuse" according to the invention, such replacement of fountain solution becomes less often required.
- fountain solution as cleaning water has the The advantage that it is compatible with the printing inks of the printing press.
- the fountain solution consists mainly of water and so-called "Additives”: Such additives are in the fountain solution of the Fountain water treatment device added to the fresh water.
- the Additions are used to set a pH value that is favorable for printing of the fountain solution, to avoid the formation of bacteria in the fountain solution, as corrosion inhibitors to prevent corrosion in the Printing machine, and / or for setting a suitable electrical Guide value of the dampening water, and / or for other purposes.
- the Dampening water often added alcohol.
- the invention is not limited to the use of a washcloth, instead, others can also work automatically Cleaning agents are used, for example rotating brushes.
- a washcloth is used, which of a cleaning cloth spindle over a pressure element, which a Press the washcloth section against the surface to be cleaned, onto a motor-driven dirt towel spindle is transportable.
- washing cloth understood, for example fabrics, knitted fabrics, plush, pile and the like.
- the supply of the cleaning device with cleaning water from the Fountain water treatment unit has other advantages: Both are housed together in a single closet; it is only one Fresh water supply from a house supply network necessary; their electrical Control devices can be replaced by a common control device and / or via a common data interface to the parent Control device of the printing press can be connected.
