In copy paper device A1, pulp suspension S is supplied on copy paper net 23 from head box 12, to form l Water Paper W.

Control unit 8 cooperates the opportunity that pulp suspension S is conveyed to head box 12, on the opportunity started herein for conveying, makes to connect Nearly component 67 is moved to intercepting position from position of readiness close to copy paper net 23.

It is specifically described below.When the driving of control unit 8 is close to driving portion 77, drive shaft 78 is using close to driving portion 77 Driving and rotate, set up axis 73 rotated by band 75 and pulley 74.Cam 71 rotates specified amount as a result,.

In Fig. 3, using the rotation of cam 71, the supporting cam wheel abutting part 81 from below of the cam 71 shown in the double dot dash line State, the state that the cam 71 for becoming shown in solid is not contacted with cam abutting part 81.During this period, bent member 69 by The active force of biasing member 70 moves downwards with the rotation of cam 71.

Moreover, be fixed on the catching sheet 36 close to component 67 of 80 lower part of stringer board along with the movement of stringer board 80 and downwards It is mobile.

The upper surface of the lower ora terminalis contact copy paper net 23 of catching sheet 36, and catching sheet 36 by biasing member 70 towards copy paper Net 23 exerts a force, and becomes the state of the upper surface of pressing copy paper net 23.

Pulp suspension S flows into reservoir 18 from the inflow part 20 of head box 12.Moreover, pulp suspension S is in supply plate It circulates, and is supplied on copy paper net 23 on 33.In addition, control unit 8 not yet starts the loopy moving of copy paper net 23, copy paper net at this time 23 keep stopping.

In this way, being supplied to copy paper net 23 to from head box 12 in the state of making to contact copy paper net 23 close to component 67 The flowing of pulp suspension S is intercepted, and pulp suspension S is prevented to flow to downstream side.

The pulp suspension S being supplied on copy paper net 23 is trapped in intercepted plate 36 and pair of right and left limiting member 34 surrounds Space in, liquid portion pass through copy paper net 23 mesh.

The liquid portion of pulp suspension S is below the inner side of the circular orbit of copy paper net 23 is oriented to by water removal plate 26 Water-accepting part 27.Moreover, after by 27 water receiving of water-accepting part, in receiving to plain boiled water container 29.Plain boiled water in plain boiled water container 29 is sent It is utilized to regenerated paper pulp manufacturing department 1 and deinking portion 2 etc., and again.

Remaining regenerated paper pulp is formed as comprising the fibrous layer that is, l Water Paper W compared with juicy on copy paper net 23.Control unit 8 exists After reservoir 18 is on copy paper net 23 with the pulp suspension S of defined service time supply specified amount, stop from inflow Portion 20 supplies pulp suspension S to head box 12.Along with this, it is outstanding also to terminate to supply paper pulp on copy paper net 23 from head box 12 Supernatant liquid S.

Control unit 8 makes pulp suspension S be stranded in delay portion 68, liquid portion with the defined residence time in this condition Divide and be directed downward, reduces the moisture content of l Water Paper W.

Then, control unit 8 drives close to driving portion 77.Utilize the driving close to driving portion 77, the rotation regulation of cam 71 angle Degree, the top of cam 71 contacts with cam abutting part 81, overcomes the active force of biasing member 70 and jack up cam abutting part 81.

The catching sheet 36 in intercepting position rises upwards and is moved to position of readiness as a result,.The lower end of catching sheet 36 Edge leaves the upper surface of copy paper net 23.

By being detained pulp suspension S on copy paper net 23, being kept for the defined residence time, formed on copy paper net 23 Fibrous layer.The moisture content of the fibrous layer is low, and front end portion, that is, paper web front end area thickening is formed as specified altitude.

Therefore, even if catching sheet 36 leaves copy paper net 23, the fiber on copy paper net 23 will not flow to downstream side but stagnant It stays in delay portion 68.

On the other hand, liquid portion is supplied by the fibre concentration of pulp suspension S, residence time, on copy paper net 23 The influence of the feed speed of pulp suspension S etc. largely flows to the downstream side of the direction of the supply of pulp suspension, sometimes sometimes It can flow out a small amount of, it is also possible to hardly flow out.

Next, control unit 8 drives net driving portion.Using the driving of net driving portion, copy paper net 23 is mobile, before l Water Paper W The abutting part 30 of end part arrival copy paper net 23 and dewatering bands 31.

When the l Water Paper W on copy paper net 23 reaches the abutting part 30 of copy paper net 23 and dehydration band 31, l Water Paper W is from copy paper net 23 shift to dehydration band 31.It is mobile that dehydration band 31 carries the paper web in moisture state.In the setting of dehydration roller portion 43 At position, clamps and press paper web and be dehydrated.Then, paper web is shifted towards drying with band 47.

When the front end portion of paper web is close to the setting position of front end stripping portion 52, control unit 8 drives swing part 57, makes to shell From plate 56 as shown in double dot dash line in Fig. 2 counter-clockwise swing.

Then, the front side ora terminalis of peel plate 56 is contacted with dry with band 47, will be carried on the dry lower surface with band 47 Paper web front end area is removed from dry with band 47.At this point, the thickness of paper due to paper web front end area is greater than the thickness of paper of paper web main region, So the front side ora terminalis of peel plate 56 is easily connected to the leading edge of paper web front end area, can reliably be removed.

In this way, by paper web front end area, after the dry removing with band 47, control unit 8 drives swing part 57 again.Then, Using with aforementioned opposite movement, make the clockwise oscillation in Fig. 2 of peel plate 56, swing to peel plate 56 with dry with band 47 Non-contacting position.

After having passed through calendering portion 54 with the paper web front end area that band 47 is removed from drying, control unit 8 makes stack 63 It is mobile from retreating position to pressing position.Then, paper web is pressed on into dry band 47 and drying drum 50 using stack 63 It pressurizes.The flatness of the recycled writing paper 7 obtained after drying is improved as a result,.

When paper web reaches the dry abutted position for using band 47 and clamping band 48, paper web is clamped in dry with 47 He of band Between clamping band 48.Then, paper web is across the dry drying drum 50 for being connected to band 47 and being heated mechanism 62 and heating.By This, the paper web in moisture state is dried, the band-like recycled writing paper 7 before being finished.In addition, the temperature of drying drum 50 It is detected by temperature sensor 66, and maintains predetermined temperature.

Recycled writing paper 7 before finishing obtained in drying section 15 is removed from dry with band 47 by scraper plate 55, and on one side Not shown guiding piece guidance is sent to the finishing Ministry of worker 4 on one side.

The band-like recycled writing paper 7 for being sent to the finishing Ministry of worker 4 is cut into defined sheet size by cutting knife, completes regeneration Paper 7.At this point, cutting means cut the width direction both ends of band-like recycled writing paper along longitudinal direction.

The upper straight knife of cutter is moved up and down relative to lower straight knife, cuts recycled writing paper along width direction.Cropped knife is cut The leftover pieces of recycled writing paper 7 be recycled to leftover pieces recycling bins.As shown in Figure 1, the leftover pieces in leftover pieces recycling bins return to Regenerated paper pulp manufacturing department 1 is used for the manufacture of recycled writing paper 7 as wastepaper as raw material again.

When forming the paper web main region connected with paper web front end area, control unit 8 can also be control as follows close to component 67 movement: driving makes then to separate close to component 67 close to copy paper net 23 close to driving portion 77.

The l Water Paper W that thereby, it is possible to make to contact the paper web main region formed on copy paper net 23 close to component 67, can be in l Water Paper The trace contacted close to component 67 is left on W.It is grasped close to amount test section 89 close to component 67 at this point, control unit 8 can use At a distance from copy paper net 23, make to be located at desired position close to component 67.

In addition, being obtained after the midway stage for forming paper web main region wishes that change is dry after initially forming l Water Paper W Paper thickness when, control unit 8 is controlled, change net driving portion drive volume, to change the movement speed of copy paper net 23.

By changing the conveying capacity of delivery pump using control unit 8, the thickness of the paper for the system of copying can be also changed.At this point, control unit 8 Cooperate the change opportunity of the movement speed of copy paper net 23 or the change opportunity of the conveying capacity of delivery pump conveying pulp suspension S extremely Few either side, drives close to driving portion 77, makes to be moved close to position close to component 67 and contact l Water Paper W.At this point, control unit 8 controls adjust the position close to component 67, contact the time of l Water Paper W and the opportunity of contact close to driving portion 77.

The label that visually can confirm that degree is formed on the paper web for the recycled writing paper 7 that can be obtained after the drying as a result,.Therefore, may be used With which time point for easily verifying that from recycled writing paper 7 change copy paper net 23 movement speed or delivery pump conveying capacity and change Thickness.

In addition, control unit 8 can also be controlled, system is copied in change during forming the l Water Paper W of paper web main region When the thickness of paper, pulp suspension S is prevented to flow to downstream side using close to component 67.

At this point, leading l Water Paper W and subsequent l Water Paper W are discontinuous, but it is cut open.It is intercepted in paper web main region Pulp suspension S-shaped becomes new paper web front end area.Therefore, the change time point of thickness of paper can be made obvious.

As described above, the paper pulp supplied from head box 12 is hanged due to having in the copy paper device A1 of present embodiment Supernatant liquid S is filtered and is formed the copy paper net 23 of l Water Paper W, and can relative to copy paper net 23 close to separation close to component 67, so By making to contact the l Water Paper W formed on copy paper net 23 close to component 67, the trace contacted close to component 67 can be left on l Water Paper W Mark.

Label can be formed on the recycled writing paper that l Water Paper W is dried to obtain as a result,.Due to when having begun to pass through regulation from copy paper Between when and the length of l Water Paper W when being equivalent to the recycled writing paper 7 of regulation piece number and terminating copy paper etc. as defined in opportunity, make close to structure Part 67 makes marks, therefore can easily manage manufacture close in the case where copy paper net 67 on the paper web of dry recycled writing paper 7 Recycled writing paper 7.

Further, since being configured to contact the upper surface of copy paper net 23 close to component 67, so can become apparent from l Water Paper W Ground leaves the trace of contact.

Moreover, because constituting delay portion 68 close to component 67, the delay portion 68 is supplied to copy paper net to from head box 12 The flowing in 23 pulp suspension S towards downstream side is intercepted, and can use close to component 67 when so forming l Water Paper W by paper Mass suspension S is intercepted on copy paper net 23.

Thus, it is possible to which the thickness of l Water Paper W is locally thickeied.

Due to having the distance between the length L of width direction and pair of right and left limiting member 34 substantially phase close to component 67 Deng catching sheet 36, so pulp suspension S can be intercepted using catching sheet 36 and pair of right and left limiting member 34, make its not to Downstream side leakage, can be such that the front end of the l Water Paper W on copy paper net 23 is linearly formed.

Sensor easy to use of control unit 8 etc. is grasped to copy paper net 23, dehydration band 31, drying and uses band 47 successively as a result, Shift the position of the front end of the paper web of conveying.

Dehydration roll portion 43 can be made to start the peel plate 56 contact drying band 47 on the opportunity of pressurization, front end stripping portion 52 Opportunity etc. that opportunity and stack 63 are moved to pressing position is time point appropriate.

When keeping the opportunity of 56 contact drying band 47 of peel plate too early, paper web front end reach front end stripping portion 52 it Before, peel plate 56 will leave dry band 47.At this point, paper web front end area cannot be removed from dry with band 47, it is difficult to will Recycled writing paper after the dry drying conveyed with band 47 is conveyed to the finishing Ministry of worker 4.

In turn, the opportunity for making 56 contact drying band 47 of peel plate too late, reaches front end in the front end of paper web and removes When making 56 contact drying band 47 of peel plate after portion 52, it is also difficult to suitably remove paper web front end area with band 47 from dry.

In addition, as in the past in the case where the structure without catching sheet 36 without intercepting pulp suspension S, copy paper net 23 The front end of the l Water Paper W of upper formation is not linearly, and is created as zigzag.

At this point, the position at the pulp suspension S high velocity stream position downstream and low speeds flow supplied to copy paper net 23 It is adjacent in the direction of the width.

Therefore, in the front end of l Water Paper W, the leading position leading to the downstream side of the conveying direction of copy paper net 23 with to The separation distance at the retrogressing position that upstream side retreats becomes larger.In addition, forming paper web front end area with being intercepted with catching sheet 36 Situation is compared, the front end of l Water Paper W it is thinner.

In this case, though control unit 8 based on copy paper net 23, dehydration band 31, it is dry with the movement speed of band 47 come It predicts the position of the front end of l Water Paper W, and carries out control correspondingly, might not also become movement appropriate sometimes.

However, in the present first embodiment, the front end of l Water Paper W is made and intercepting pulp suspension S with catching sheet 36 Portion becomes linear, so that control unit 8 can accurately calculate the position of the front end of l Water Paper W, and can be based on the position into Row controls and becomes movement appropriate.

In addition, control unit 8 is controlled, the thickness of paper of the paper web front end area formed on copy paper net 23 is made to be greater than main region paper Thickness, the main region thickness of paper are set in the paper web main region connected with paper web front end area.

Therefore, the situation identical as main region thickness of paper and front end area thickness of paper and front end area thickness of paper are than main region thickness of paper Thinner situation is compared, and can more reliably be shifted l Water Paper W from copy paper net 23 to dehydration band 31.

It, similarly can be more reliably by l Water Paper W from dehydration band 31 to dry in addition, at the setting position of dehydration roller portion 43 It is dry to be shifted with band 47.Moreover, at front end stripping portion 52, can reliably be carried on the paper web of the dry lower surface with band 47 from It is dry to be removed with band 47.

Control unit 8 is controlled, and is being started to supply pulp suspension S on copy paper net 23 from head box 12 and is being formed paper web When front end area, make the mobile stopping stipulated time of copy paper net 23, so that the thickness of paper web front end area be thickeied.

In this way, by thickening the thickness of paper web front end area, it can be more reliably successively from copy paper net 23 to dehydration band 31 and paper web is shifted with band 47 to dry.It, can be more reliably by paper web front end area from drying in addition, at front end stripping portion 52 It is removed with band 47.

In addition, waste paper regenerated processing unit 100 has regenerated paper pulp manufacturing department 1 and copy paper device, regenerated paper pulp manufacturing department 1 Waste paper is decomposed to manufacture pulp suspension S, copy paper device is provided with relative to copy paper net 23 close to separation close to component 67, institute By making to form label on the recycled writing paper that l Water Paper W is dried to obtain close to component close to copy paper net 23, can easily manage Recycled writing paper.(second embodiment)
