Abstract
Disclosed is a washing apparatus for an offset printing press, comprising several washing points on the cylinders of the printing press and a supply system for delivering water, cleaning agent, and compressed air to spray a mixture of water and cleaning agent (detergent) onto the cylinder surfaces that are to be cleaned. The inventive washing apparatus is characterized by annular ducts (14, 16, 18) for the water, cleaning agent, and compressed air, which extend from a central supply unit (10) along all potential washing points of the printing press. Said annular ducts (14, 16, 18) are provided with a number of modular washing units (20, 22) which are located directly at the washing points and are coupled to or enclosed in the annular ducts (14, 16, 18), and valves (40, 42, 48, 50, 54) for discharging water, cleaning agent, and compressed air.
Description
Technical field
The present invention relates to a kind of offset press cleaning device, on the cylinder of this offset press, be provided with a plurality of cleanings seat in the plane, and this offset press is provided with supply water, cleanser and compressed-air actuated feed system, so that the mixture (cleaning agent) of water and cleanser is sprayed onto on the cylinder surface that will clean.
Background technology
In offset printing, print pattern places on the outer surface that is known as plate cylinder.Print pattern is delivered to printing material by plate cylinder another cylinder (blanket cylinder) through being coated with rubber blanket.Impression cylinder is pressed against printing material on the blanket cylinder, and printing material has just obtained print pattern like this.
The function of cleaning device is exactly that cleaning agent is sprayed onto on the rolling drum surface of blanket cylinder and impression cylinder every now and then, cleans then.This is because in printing operation, cylinder surface can be assembled some dirts, mainly is Yu Mo and paper scrap.
For cleaning operation, use directly is contained in the washer on the relevant cylinder usually.The water and the cleanser that are mixed into cleaning agent flow to each cleaning seat in the plane from the center fed point that is formed by the cleaning agent supplying tank usually.Cleaning agent and compressed-air actuated supply are then finished by the pipeline or the flexible pipe of cleaning agent transfer pot.
Summary of the invention
The cleaning device that the purpose of this invention is to provide a kind of the above-mentioned type can reduce and lead to flexible pipe and the number of tubes that each cleans the seat in the plane, and guarantees to clean supply and identical pressure condition balanced on the seat in the plane at all.
, be characterised in that according to the cleaning device of the above-mentioned type of the present invention for this reason, comprise annulus line, be used for transporting water, cleanser and compressed air, described annulus line extends all potential cleaning seats in the plane from central feed unit along described printing machine; And a plurality of modular cleaning units, be located immediately on the described cleaning seat in the plane, and be connected, perhaps be bonded in the described annulus line with described annulus line, described a plurality of modular cleaning unit has valve, and described valve is used for discharge water, cleanser and compressed air.
According to the present invention, formed closed circuit circular line system, wherein, each modular cleaning unit all is integrated, or is connected with it.Like this, can clean the identical pressure condition that obtains to be used for cleaning agent supply and compressed air supply on the seat in the plane at all, and therefore clean the renewable distribution that seat in the plane obtains liquid at each.By disperseing all that on each printing element cleaning unit is installed, the size of central feed unit can reduce significantly.Therefore, just needn't near printing machine, place relatively large and be difficult to a control charging-tank.
The required valve of each printing element all places each modular cleaning unit that is used for each printing element, can shorten the path of valve and real cleaning machine interdigit so greatly.Contingent error in dipping is very little or can ignore fully.
The modular cleaning unit can have the integrated channel of perforation formula.
In addition, each cleaning unit can provide control impuls, to be used for by the valve of data/address bus excitaton source from the center switch jar.
Description of drawings
Below, by accompanying drawing preferred illustrative embodiment of the present invention is explained.
Unique herein accompanying drawing is the schematic diagram according to cleaning device of the present invention.
The specific embodiment
Cleaning agent and compressed-air actuated feed unit are represented with 10 in the drawings.The hardware console of data computer and electronic-controlled installation is equipped with in label 12 expressions.
Come from feed unit, have pipeline 14,16,18, cleaning agent, water and compressed air are by pipeline 14,16,18 dischargings.Several the dotted lines parallel with pipeline 14,16,18 illustrate not the return pipeline of label separately.Pipeline 14,16,18 all is designed to may extend to the annulus line of all potential cleaning positions of printing machine.
With reference to the accompanying drawings, modular cleaning unit 20,22 all is integrated in the circular line system that comprises pipeline 14,16,18 and return pipeline thereof.Has passage 24,26,28 in these cleaning units.
Cleaning unit 20,22 is used for each printing element of printing machine or cleans the seat in the plane.
For example, cleaning unit 20,22 has frame-like or case shape structure, and pipeline 24,26,28 passes them, and these pipelines can be integrated in total circular line system or with it and be connected.In the exemplary of Xian Shiing, pipeline 24,26,28 has constituted the part of total circular line system in the drawings.
Pressure override valve 30,32,34 is positioned among the annulus line 14,16,18, is used to limit the interior internal pressure of pipeline of circular line system, and avoids pressure peak.
In cleaning unit 20,22, pipeline 24,26,28 can be connected with tap line 36,38, for example, is used for guaranteeing that cleaning agent is transported to first tap line of cleaning the seat in the plane from the pipeline 14 of circular line system.For example, tap line 36 offers cleaning seat in the plane on the blanket cylinder to cleanser, and tap line 38 then can be used to guarantee the supply of water.Valve 40,42 is contained in these two pipelines, and description can be done in the back at this point again.
Further, tap line 44,46 is derived from annulus line 16.They are used for supplying water to the cleaning seat in the plane on the blanket cylinder.Valve 48,50 is installed in the tap line 44,46.
Tap line 52 with valve 54 is connected with carrying compressed-air actuated annulus line 18.
Tap line 36,38,44,46 is led to for example jet strip (not shown), and jet strip is parallel with blanket cylinder and have a nozzle of a plurality of aligning blanket cylinders.Water and cleanser enter in the jet strip, then provide compressed air by another tap line 52 again, go out through nozzles spray so make the mixture (being also referred to as cleaning agent at this) that is made into betwixt.
Second cleaning unit 22 is used for for example cleaning impression cylinder.
Certainly, accompanying drawing only shows an embodiment.With regard to the large-sized print machine, can amplify the circular line system of describing in the present embodiment significantly.In bigger machine, the concrete advantage of the present invention significantly and clearly embodies.
Before illustrate, data computer places in the hardware console 12, so just can form the central microprocessor by-pass valve control by control circuit, this central microprocessor by-pass valve control is born control to the valve of all cleaning units 20,22 by control circuit 56,58.
