Description

Cylinders of printing press cleans equipment therefor and method

Cleaning device that uses when the present invention relates to the cleaning printing press cylinder and method.

In the past, purging system has been used for the printing cylinder of cleaning printing press.Particularly purging system is used to following situation: be wrapped in the cleaning cloth on supply core tube and the feed spool, be cleaned device and send and contact with cylinders of printing press and clean it.Cleaning cloth uses the back and is twisted on the spool.This system is at United States Patent (USP) the 5th, 176, open in No. 080 (the Mitja Gaspari Buddhist nun, etc.), only for reference here.

In use, the spool of drum driven is by rotating cleaning cloth from being rolled onto on the spool for cloth rewinder roll.This progressive be used to prevent too much cleaning cloth from pulling out, thereby the work that prevents to use cleaning cloth too much and hinder printing machine for cloth rewinder roll to distribution system.For making this progressive distribution system of giving effective, must prevent to supply relatively rotating between core tube and the feed spool.Up to the present, the use clamping system will supply the core tube and feed spool is tied, to prevent relatively rotating between them.This clamping device uses a series of pins or pawl to catch feed spool and supply core tube simultaneously.This device also has an arrestment mechanism, when said device at a touch during the jack on the axle, produces the spring converse rotating force.

Yet,, use said pawl to still have some deficits aspect the relatively rotating of core tube and feed spool guaranteeing to prevent to supply sometimes because usually said core tube shrinks problem.The core tube shrink to be owing to make due to the material of core tube or form in manufacture process.This problem has caused a feed spool weak point that other supply core tube assembles than it.Therefore, if attempt will be tied than short core tube and than long axle with pawl, then because the core tube is shorter, pawl can not be tied supplying core tube and feed spool.Particularly, when pawl has been fixed on when spool last, because pawl can not touch the core tube, so core tube and axle can not be tied.Therefore, when the drum driven spool when feed spool is pulled out cleaning material, since the core tube not and axle be not tied, brake apparatus and spring are swung to device and can not be played a role, thus link to each other with feed spool progressively can not prevent that to distribution system too much cleaning cloth from entering printing machine.Say that exactly supply core tube will rotate relative to feed spool when spool rotates, thereby has transmitted too much cleaning cloth to printing machine.Therefore, printer system can be owing to too much cleaning cloth blocks.Like this, because supply core tube does not have and feed spool is tied rightly, too much cleaning material has been wasted.

Therefore, be necessary to propose the problem that the core tube shrinks,, reduce the card cloth phenomenon when using this purging system cleaning printing press cylinder simultaneously so that cylinders of printing press suitably cleaned.

The cylinders of printing press purging system that uses also exists the other problem at present.Particularly, the spool that this system uses adopts hackly surface usually, forms a kind of zigzag friction surface of uniqueness, when rotating with convenient spool cleaning cloth is bonded on the axle.When spool rotates, this hackly surface will prevent relatively rotating of used cleaning cloth and spool.Therefore, when the drum driven spool rotated, because the cleaning cloth of useful mistake is bonded on the hackly surface of spool, spool can have been pulled out extra cleaning cloth from supply core tube.

Yet this hackly surface may be the part trouble concerning the user, particularly when spool is metal.Therefore, be necessary to propose how to prevent relatively rotating between used cleaning cloth and the spool, and don't make the operator face the possible incised wound and the problem of scuffing.

Another problem relevant with the cylinders of printing press purging system that uses at present when changing cleaning cloth is unusual difficulty with spool and feed spool dismounting.Therefore, need the link system of an enhancing, so that when changing cleaning cloth, can dismantle and reload feed spool and spool easily.

The present invention satisfies the demand.

According to the present invention, the objective of the invention is to overcome the problem that aforementioned existing cylinders of printing press purging system exists.

Referring to accompanying drawing, be detailed introduction below to each suggested design of the present invention.

Referring to Fig. 1, the view of press printing cylinder purging system 10 is disclosed among the figure.Said purging system 10 is made of a bracing strut 50 that rotates feed spool 20, supply core tube 30, a spool 40 usually, will carry out very detailed introduction below to described each parts.

Continuation is referring to Fig. 1, and the feed spool of rotation is begun till the second end 70 by first end 60.Usually the feed spool 20 that rotates is a solid construction except that the hollow space that is useful on the installation shaft plug in each end.First plug 80 is inserted in 60 li of the first ends of the feed spool 20 of rotation.Second axle plug 90 is inserted in 70 li of the second ends of the feed spool 20 of rotation.The part of each

plug

80,90 is inserted in the hollow ends of feed spool 20.The horizontal projection that each

plug

80,90 exceeds feed spool 20 external diameters in addition is to prevent to be enclosed within supply core tube 30 slippage from the feed spool 20 on the feed spool 20.Each

axle plug

80,90 also has axis hole coupling part 100,110, and these coupling parts are tied the tumbler 120,130 in axle plug (thereby will rotate feed spool 20) and tape spool hole.In case be tied, feed spool 20 and axle plug can rotate by the tumbler 120,130 of axis hole going along with under the effect of brake force and counteracting spring tension force.The tumbler 120,130 in tape spool hole is installed on the bracing strut 50, and the tumbler 120,130 in feed spool 20 and the

axle plug

80,90 that links with it, tape spool hole together rotates around the axis 140 of feed spool 20 when the rotary action masterpiece is used on the feed spool 20.

Rotate preferably aluminium matter of feed spool 20.The tumbler 120,130 in

axle plug

80,90 and tape spool hole is galvinized steel preferably.Bracing strut 50 is aluminium matter preferably.Yet it is understandable making above-mentioned parts with other suitable material.

Continuation is supplied core tube 30 as shown in the figure and is enclosed within on the feed spool 20 referring to Fig. 1.Because supply core tube 30 is enclosed within on the feed spool 20, so supply core tube 30 begins to finish to the second end 160 from first end 150.The inside of supply core tube 30 is the holes that extend to the second end 160 from first end 150, in order to suit feed spool 20.Supply core tube 30 is preferably used the cardboard manufacturing, and other suitable material is also passable certainly.

What twine on the supply core tube 30 is cleaning material 170.Said cleaning material is 5,368, No. 157 disclosed cleaning materials of United States Patent (USP) preferably, and only for reference here, the cleaning material 170 of other type for example cleans film certainly, also can use.

Fig. 2 and Fig. 3 A～3F are the views that is enclosed within the supply core tube 30 on the feed spool 20, and they are separated from other parts of purging system of the present invention.Fig. 3 A～3F particularly, they are various embodiment of the present invention.Usually, by the exterior cross-section 180 of feed spool 20 and the internal structure cross section 190 of supply core tube 30 feed spool 20 and supply core tube 30 are tied, to prevent relatively rotating between them.Being seen in figure, the exterior cross-section of the feed spool 20 of rotation is polygon (Fig. 3 A～3E) or oval (Fig. 3 F), and the internal structure cross section of supply core tube 30 is polygon (Fig. 3 A～3E) or oval (Fig. 3 F).Particularly point out, but internal structure cross section triangle (Fig. 3 A), rectangle (Fig. 3 B), pentagon (Fig. 3 C), hexagon (Fig. 3 D) or the ellipse (Fig. 3 F) of the exterior cross-section 180 of feed spool 20 and supply core tube 30.Shown in Fig. 3 E, the exterior cross-section of supply core tube 30 is not both understandable with the internal structure cross section of supply core tube 30.Therefore the exterior cross-section at Fig. 3 E SMIS tube is round, and the internal structure cross section is a square.Therefore the outer surface of core tube can be the face of cylinder, and the inner surface right and wrong face of cylinder.

In a word, the inner surface cross sectional shape 190 of the outer surface cross sectional shape 180 of feed spool 20 and supply core tube 30 can be any non-circular curve.According to definition, circumference is the plane curve of a sealing, and the distance of every bit fixed distance point (center of circle) equates on the curve.Therefore, non-round closed curve has a central point and a periphery, has at least the distance of 2 distance center points different on the periphery.Like this, the inner surface cross section 190 of the outer surface cross section 180 of feed spool 20 and supply core tube 30 can be an arbitrary shape, and this shape has a central point and a periphery, has at least the distance of 2 distance center points different on the periphery.

As long as the inner surface cross section 190 of outer surface cross section of feed spool 20 180 and supply core tube can be with

feed spool

20 and 30 engagements of supply core tube, and can prevent to relatively rotate between them, the outer surface cross section 180 of feed spool 20 can be different with the shape in the inner surface cross section 190 of supply core tube 30 so.

At work, this version is rotated feed spool 20 and supply core tube 30 synchronously, thereby has made things convenient for the transmission of cleaning material 170, because at this moment feed spool 20 rotates together with supply core tube 30.。

Referring to Fig. 1,4 and Fig. 5 A～5D, shown in the figure is rotating spool 40 among the present invention.Said spool 40 begins to finish to the second end 194 from first end 192.Each have bossy body 196,198 and bracing strut 50 connections in each end.Shown in Fig. 5 A～5D, the cross section of said spool 40 is polygon preferably, as triangle (Fig. 5 A), rectangle (Fig. 5 B), pentagon (Fig. 5 C), hexagon (Fig. 5 D), so that can be wrapped on the spool 40 with the cleaning material of crossing, and without adopting coarse hackly surface structure on the spool 40.As feed spool 20 and supply core tube 30, various non-circular shapes can be adopted in the cross section of spool.

Referring to Fig. 1, runner 199 and spool 40 link, and spool 40 is rotated in the process of cleaning printing press cylinder.At work, runner 199 drives spools 40 and rotates, thereby pulls cleaning material 170 from core tube 30, and make feed spool 20 and supply core tube 30 rotate (with at United States Patent (USP) 5,176, disclosed progressive feeding system links in No. 080).

Spool 40 is aluminium matter preferably, uses other suitable material also to be fine certainly.

Fig. 6～shown in Figure 9 is another embodiment of use key of the present invention system.Wherein, feed spool 200 and supply core tube 210 are by using the key system to be meshed.In Fig. 8, can most clearly find out have

keyway

220 and 230 to hold

key

240 and 250 on the supply core tube 210.Can find out most clearly that in Fig. 8 and Fig. 9 feed spool 200 has an inner chamber 260 to be used for the part of fitting key system necessity.Feed spool 200 also has

groove

270 and 280 on its sidewall.Usually, can find out most clearly in Fig. 9 that key 240 and 250 enters

keyway

220 and 230 along

groove

270 and 280 and is meshed with supply core tube 210, and feed spool 200 is connect mutually with supply core tube 210, prevents to occur between them relatively rotating.Keyway 220 and 230 minimums also should be able to be held key 240 and 250, and it is big that

keyway

220 and 230 cans be compared to said minimum dimension most, so that there is certain clearance to satisfy the needs of feed spool 200, supply core tube 210 and key system manufacturing tolerance.

Continuation uses located lateral pin 290 to prevent that the key system from being compressed into chamber 260 too much referring to Fig. 8 and Fig. 9.In the present embodiment, feed spool 200 can be in Fig. 8 makes in the right side scope of located lateral pin 290 solidly, and makes the key system fully in the left side of alignment pin.See Fig. 8, spring 300 is installed in the left side of located lateral pin 290.One end of said spring 300 can be fixed on the alignment pin 290 by clip.The other end of said spring 300 and slidably cam member 310 connections.Spring 300 preferably has at least an end to be fixed on alignment pin 290 or slidably on the cam member 310, so that spring 300 is all the time at alignment pin 290 with slidably between the cam member 310.This structure can guarantee cam member 310 slidably by non-locked position shown in Figure 8 when latched position shown in Figure 9 is slided, 300 pairs on spring slidably cam member 310 and located lateral pin 290 applies active force.

Slidably oblique cam surface 320 of first of

cam member

310 and 240 engagements of first key, second oblique cam surface 330 and second key 250 engagement.Slidably cam member 310 has a long-neck 340 between its two cam surfaces 320,330.In addition, slidably cam member 310 has a groove 350 to be used to hold steady pin 360.When slidably cam member 310 slided into latched position shown in Figure 9 by non-locked position shown in Figure 8, an end of said steady pin 360 and groove 350 was meshed, and prevented that slidably cam member 310 moves in the chamber 260 of feed spool 200 further.

Continuation is referring to Fig. 8 and Fig. 9, and being also shown in first key 240 in the drawings has 370, the second keys 250 in an inclined-plane that an inclined-plane 380 is arranged.The inclined-plane 370 of first key 240 be designed to and slidably first oblique cam surface 320 of cam member 310 be meshed.The inclined-plane 380 of second key 250 be designed to and slidably second oblique cam surface 330 of cam member 310 be meshed.

Key

240 and 250 respectively has a pin to be used for connecting mutually with spring 390, said spring with two

keys

240 and 250 toward drawing together.So, when said key system was in unlock state,

spring

300 and 390 made slidably that cam member 310 is in high order end position shown in Figure 8.When spring 300 applies effect and makes that slidably cam member 310 slides to above-mentioned position, spring 390 simultaneously with

key

240 and 250 to drawing together, thereby the inclined-plane 370,380 of key 240,250 is meshed with the inclined-plane 320,330 of sliding cam spare 310, shift sliding cam spare 310 onto said non-locked position.

Axle plug 400 has insert 410, horizontal bossy body 420 and stop pin 430, and use axle plug 400 slidably cam member 310 pushes latched position shown in Figure 9 from described non-locked position.The size of insert 410 should make in its chamber that can enter feed spool 200 260.After insert 410 entered chamber 260, insert 410 contacted with cam member 310 slidably.If the user constantly firmly is pressed into insert 410 in the chamber 260, slidably cam member 310 will be shifted onto its latched position from its non-locked position.When sliding cam spare 310 is pulled to its latched position, the inclined-plane 370 of the first oblique cam surface 320 and first key 240 is meshed, the inclined-plane 380 of the second oblique cam surface 330 and second key 250 is meshed, thereby makes said key 240,250 slip into the keyway of supplying on the core tube 210 220,230 along the groove on feed spool 200 sidewalls 270,280.The length of the insert 410 preferably length of groove 350 adds the distance of slip insert 410 ends to feed spool 200 ends.The horizontal bossy body 420 of axle plug 400 is thicker than feed spool 200, so bossy body 420 helps to prevent to supply core tube 210 slippage from the feed spool 200.Yet because said key system can prevent to supply core tube 210 slippage from the feed spool 200, the axle plug need not have above-mentioned horizontal projecting member.Axle plug 400 also has a stop pin 430, and stop pin 430 slides into same locking cotter way 450 on feed spool 200 sidewalls through the cotter way 440 on feed spool 200 sidewalls.For axle plug 400 being locked in the first end 60 of feed spool 200,400 of axle plugs need rotate slightly so that stop pin 430 enters locking cotter way 450, and stop pin 430 is meshed with sidewall around the feed spool 200 of said locking cotter way 450.It should be noted that said key system can have only a key and a keyway on core tube and axle, rather than two keys shown in the figure, two grooves.

Said key system preferably adopts galvinized steel and other metal material, though use other suitable material to be fine.

Referring to Figure 10 and Figure 11, an alternative embodiment of the invention has also been used the key system.In this embodiment, key 500 laterally protrudes on the sidewall of axle 510.Said key 500 and said sidewall can be one.Said key 500 can enter the keyway 520 of supply core tube 530, and groove 520 begins to any point the supply core tube two ends from an end of feed spool 530.Though said embodiment has two axle plugs 540,550 among Figure 10 and Figure 11,540 pairs of first shown in Figure 11 spool plugs prevent to supply core tube 530 slippage not necessarily (said key system is enough to prevent to supply slippage on the end at core tube 530 axle plug 540 places from the feed spool 510) from the feed spool 510.In case supply core tube 530 is enclosed within on the feed spool 510, said key 500 enters keyway 520, just relatively rotating and can avoid between feed spool 510 and the supply core tube 530.

Referring to Figure 12, another embodiments of the invention as shown in the figure.In this embodiment, the key system of feed spool 600 and supply core tube 610 is made of a plurality of grooves on feed spool 600 and the supply core tube 610, to prevent relatively rotating between them.

In Figure 13, introduced a kind of mounting means of the uniqueness that spool 40 can be rotated on bracing strut 50.In this mounting means, spool 40 can slip into bracing strut 50 via groove 700.In case spool 40 is bound up via groove 700 and bracing strut 50, can the securing rod 720 of activity be tightened onto latched position by non-locked position with screw 710.The non-locked position of movable securing rod dots in Figure 13, and latched position is represented with solid line.This mounting means also can be used for the connection of feed spool and bracing strut 50.

By some embodiments of the present invention are illustrated and describe, should see that many concrete implementations can also be arranged under the situation that does not deviate from the spirit and scope of the invention.Therefore, the present invention is not limited to the description that carry out the front, but makes an explanation according to the scope of claim.
