Abstract
A device for cleaning the outer cylindrical surfaces of cylinders in a rotary printing machine includes a cleaning cloth extending over the length of a respective cylinder and cooperating with a pressing-on element. The cleaning cloth is pressable against a respective outer cylindrical surface by the pressing-on element. The pressing-on element includes an elastically deformable body having an internal cavity. As internal pressure is applied to the hollow body, the hollow body expands, and the distance between the elastical hollow body and the outer cylindrical surface of the cylinder can be enlarged.
Description
The present invention relates to a device that is used for cleaning outer cylindrical surfaces of cylinders in rotary printing machine, it has one along the cleaning cloth that extends on the roller length and an extrusion element that is mated effect, this cleaning cloth can be expressed on the perimeter surface of doing motion and the ducted body of the elastically deformable that this extrusion element is pressed in can applying by constitutes by extrusion element simultaneously, but its elastic expansion when in applying, pressing.
DE30054690 C
2Shown so clear leaf device, wherein after interior pressure is interrupted, between cleaning cloth and outer cylindrical surfaces of cylinders, only produce a less spacing, therefore, for example when the perimeter surface of a roller of cleaning, the grippers pawl of An Zhiing just may cause the damage to cleaning cloth herein.Will hinder like this, the cleaning of the outer cylindrical surfaces of cylinders that clean, that is cause unclean, so, the effect that cleaning device can not be realized ideal.
Based on this prior art, task of the present invention is when cleaning device interrupts, and makes that the distance between perimeter surface that will clean and cleaning cloth enlarges.
According to the present invention, above-mentioned task so solves: the air of ducted body is supplied with by a two-way valve and is realized; This two-way valve can be transformed on the negative pressure from high pressure, in order that, resting position through a neutrality moves to a position of shrinking inwards to this ducted body from a position of outwards stretching, if cleaning device of the present invention is corresponding to a print roller setting, then just can apply a negative pressure at the machine run duration, like this, the grippers pawl just can by the time can not damage cleaning cloth.
When the machine inactive state, there is not negative pressure feeding, then ducted body is in the inactive state of a neutrality, and wherein this cleaning cloth does not contact with outer cylindrical surfaces of cylinders yet.
Preferred construction scheme of the present invention is, this ducted body has an outside arch when not having air to apply the neutral resting position of effect cross section.When if this ducted body is made by the material of a rubber like, then can have and realize a solution of simply finishing above-mentioned task in the embodiment of less relatively high pressure or negative pressure at this.
One embodiment of the present of invention have been done in the accompanying drawings to simplify and have been described.
The roller 1 of a rotary press is provided with the extrusion element 3 of a cleaning device for its perimeter surface 2 correspondences of cleaning.A cleaning cloth 4 can be expressed on the perimeter surface 2 by this extrusion element 3, just dirt on the perimeter surface 2 of live-rollers 1 and remaining printing ink can be cleaned with this cleaning cloth.
In a preferred embodiment, this extrusion element is made of the ducted body 5 of an elastically deformable, for example makes and is placed in the supporting rail 6 by the material of a rubber like.A hose coupling 7 of using for air supply is set handing on the support rail 6, it connects a two-way valve 8.This two-way valve 8 links to each other with an air extractor 10 with a pressure air generator 9.In order that according to the position of two-way valve 8, the air supply of ducted body 5 can be transformed on the low pressure from high pressure.This two-way valve 8 the mark the position in the time this ducted body 5 be subjected to negative pressure.
This ducted body 5 has been described the resting position of a neutrality with chain-dotted line in the accompanying drawings.When the state of being described by fine line, this ducted body 5 is expressed to cleaning cloth 4 on the perimeter surface 2.When ducted body 5 was subjected to negative pressure, then its position with dashed lines that shrinks inwards showed.According to this, use this solution, just can realize that cleaning cloth 4 opposed rollers 1 perimeter surface 2 is in the spacing 11 by there being obviously to strengthen between putting and leaving.Be clear that thus this ducted body 5 has the cross section of an outside arch when not applying the neutral resting position of air effect.
Parameter is numbered 1 roller, 2 perimeter surface, 3 extrusion elements, 4 cleaning cloths, 5 ducted bodies, 6 supporting rails, 7 hose couplings, 8 two-way valves, 9 pressure air generators, 10 aspirators, 11 spacings
Claims (2)
1, the device that is used for cleaning outer cylindrical surfaces of cylinders in rotary printing machine, has one along the cleaning cloth that extends on the roller length and an extrusion element of mating reaction with it, simultaneously, this cleaning cloth can be expressed on the perimeter surface of doing motion by extrusion element and this extrusion element is made of a ducted body that can apply interior elastically deformable of pressing, when pressing in applying, it, it is characterized in that with regard to elastic expansion:
The air supply of ducted body (5) realizes by a two-way valve (8); With
This two-way valve (8) can be switched on the negative pressure from high pressure, in order that this ducted body (5) can move to a position of shrinking inwards through a neutral resting position from a position of outwards stretching.
2, by the described device of claim 1, it is characterized in that:
This ducted body (5) has an outside arch when not having air to apply the neutral resting position of effect cross section.
