Control unit 150 starts the second sieve motor 60a and the second translator 74b, thus start roller portion 61 and The driving (step ST8) of reticular zone 72.Hereafter, control unit 150 is allowed to start the calender roll 85 of forming section 80 and heating roller 86 Movement (step ST9), and terminate starting sequence.

Fig. 7 is the flow chart that the setting processing of step ST1 of Fig. 6 is shown in detail.

Control unit 150 is judged (step ST21) with the presence or absence of defibrating material MB to the inside in roller portion 41.Defibrating material The presence or absence of MB, such as can also be judged according to the input implemented by touch sensor 117.

It is being judged as (step ST21 the case where defibrating material MB is not present in the inside in roller portion 41；It is no) under, as to The condition that the speed of one sieve motor 40a is accelerated, control unit 150 are set (step ST22) to First Speed condition, And end setup is handled.

(step ST21 the case where being judged as the inside in roller portion 41 there are defibrating material MB；It is) under, control unit 150 is right Whether a reference value included in benchmark Value Data 162 is with enterprising for the humidity detected as the first temperature humidity test section 323 Row judgement (step ST23).Situation (the step ST23 of a reference value or more is in humidity；It is) under, control unit 150 is to defibrating material Whether the length of fiber included in MB more than a reference value included in benchmark Value Data 162 is judged (step ST24)。

Situation (the step ST24 of a reference value or more is in the length of fiber；It is) under, as to the first sieve motor 40a The condition that is accelerated of speed, control unit 150 sets (step ST25) second speed condition, and at end setup Reason.

In addition, in fiber (step ST24 the case where being shorter in length than a reference value；It is no) under, as to the first sieve motor The condition that the speed of 40a is accelerated, control unit 150 sets (step ST26) third speed condition, and end setup Processing.

On the other hand, (step ST23 the case where humidity is lower than a reference value；It is no) under, control unit 150 is in defibrating material MB Whether the length for the fiber for being included more than a reference value included in benchmark Value Data 162 is judged (step ST27).

Situation (the step ST27 of a reference value or more is in the length of fiber；It is) under, as to the first sieve motor 40a The condition that is accelerated of speed, control unit 150 sets (step ST28) fourth speed condition, and at end setup Reason.

In addition, in fiber (step ST27 the case where being shorter in length than a reference value；It is no) under, as to the first sieve motor The condition that the speed of 40a is accelerated, control unit 150 is set (step ST29) to the 5th velocity conditions, and end setup Processing.

First to the 5th velocity conditions are base in the case where accelerating speed VB from zero in the starting in roller portion 41 This condition, and the target velocity including the first sieve motor 40a and the time until reaching target velocity or the first sieve The acceleration of sub-motor 40a.

Fig. 8 is the exemplary chart for indicating the variation of the thickness of movement speed VB and the first tablet W1 in roller portion 41.Speed Spend the detected value that VB is the first sieve speed detecting portion 321, the detection with a thickness of first thickness test section 324 of the first tablet W1 Value.

(1) of Fig. 8 indicates speed VB, and (2) of Fig. 8 indicate the thickness of the first tablet W1.That is, (2) of Fig. 8 are shown The detected value of first thickness test section 324 in the case where speed VB changes as (1) of Fig. 8.The longitudinal axis is speed VB And first tablet W1 thickness, the coordinate 0 of the longitudinal axis indicates speed 0 (halted state) and the thickness 0 of the first tablet W1.Fig. 8 Horizontal axis be the time process, coordinate 0 is equivalent to point at the beginning of starting sequence.After having started starting sequence, by One sieve motor 40a starts to be set as moment T1 at the time of rotation.

In addition, the target value set about the thickness of the first tablet W1 is set as thickness TH1.In the action example, reason Thinking situation is, the thickness of the first tablet W1 is maintained as thickness TH1.Although thickness TH1 can for example be set as the model of 2mm~10mm Interior included value is enclosed, but both can be thicker, it can also be relatively thin.

Fig. 8 is control unit 150 according to First Speed condition and to the example that the first sieve motor 40a is controlled, and Value detected by first thickness test section 324 is shown in (2) of Fig. 8.

In the example of Fig. 8 and aftermentioned Fig. 9~Figure 12, the target velocity of speed VB is set to speed V1.Target Speed V1 is equivalent to First Speed of the invention.Although target velocity V1 can be for example set as in the range of 50rpm~1000rpm The value for being included, but both can for more low speed, or high speed.

In addition, in the following description, the time needed in order to which speed VB is accelerated to target velocity V1 is known as adding The fast time.

First Speed condition is, at moment T2, speed VB reaches the condition of target velocity V1.In other words, when acceleration Between be, until from moment T1 to moment T2 during TE1.Although period TE1 can for example be set as institute in the range of 1 second~10 seconds The value for including, but both can be the shorter time, or for a long time.

As described above, when starting roller portion 41 in the state of being the inside in roller portion 41 there are defibrating material MB, The amount of the first screening object MC declined from roller portion 41 can be temporary compared with the case where defibrating material MB is not present in roller portion 41 Become more.Therefore, first dropped on reticular zone 46 after the first sieve motor 40a starts rotation screens the amount of object MC and fits It is compared in the amount of the manufacture of thin slice S, also can temporarily become more.As a result, the thickness of the first tablet W1 is more than as shown in Fig. 8 (2) Thickness TH1, the peak value TH2 of thickness are significantly greater than thickness TH1.

Control unit 150 is in roller portion 41 there are in the case where defibrating material MB in the setting processing of Fig. 7, to Any one condition in two to the 5th velocity conditions is set.Second to the 5th velocity conditions make speed VB in pre- timing It is interior to be lower than target velocity V1.Specifically, the acceleration time is made to be longer than period TE1.

Second speed condition is set in the case of following, and the situation is that there are defibrating materials in roller portion 41 MB, humidity detected by the first temperature humidity test section 323 is more than a reference value, and feelings of the fibre length more than a reference value Condition.Second speed condition is to implement the condition adjusted in acceleration time mode elongated compared with period TE1.Therefore, second At the time of speed VB reaches target velocity V1 under velocity conditions compared with moment T2 and rearward.

Fourth speed condition is set in the case of following, and the situation is that there are defibrating materials in roller portion 41 MB, humidity and a reference value detected by the first temperature humidity test section 323 are comparably low humidity, and fibre length is in a reference value Above situation.Humidity compared with situation situation set by the second speed condition in roller portion 41 is lower, The amount of the first screening object MC declined from roller portion 41 temporarily becomes more.Therefore, fourth speed condition is, with the acceleration time with Second speed condition implements the condition adjusted compared to elongated mode.Speed VB reaches target velocity V1 under the conditions of fourth speed At the time of under the conditions of second speed at the time of compared with and rearward.

Third speed condition is set in the case of following, and the situation is that there are defibrating materials in roller portion 41 MB, humidity detected by the first temperature humidity test section 323 is more than a reference value, and fibre length is shorter than the feelings of a reference value Condition.Fibre length is shorter compared with situation situation set by the second speed condition, declines from roller portion 41 The amount of first screening object MC temporarily becomes more.Therefore, third speed condition is, with the acceleration time compared with second speed condition Elongated mode implements the condition adjusted.At the time of speed VB reaches target velocity V1 under the conditions of third speed and second speed Under the conditions of at the time of compare and rearward.

In addition, then arriving speed VB when being compared to third speed condition and fourth speed condition and reaching target velocity Time needed for until V1 both may be the same or different.

The length consideration of acceleration time is following because usually determining, the factor is that the humidity in roller portion 41 is sieved to first Select the influence caused by the slippage of the first screening object MC of the fibre length of influence and defibrating material MB caused by the slippage of object MC Which of be affected.

The fiber for being greater than defibrating material MB is influenced caused by the slippage of the first screening object MC in the humidity in roller portion 41 In the case where being influenced caused by slippage of the length the first screening object MC, preferably, the acceleration time quilt of fourth speed condition It is adjusted to be longer than the acceleration time of third speed condition.In addition, decline of the humidity to the first screening object MC in roller portion 41 It is excellent in the case where being influenced caused by slippage of fibre length of the influence less than defibrating material MB caused by amount the first screening object MC It is selected as, the acceleration time of third speed condition is adjusted to be longer than the acceleration time of fourth speed condition.

5th velocity conditions are set in the case of following, and the situation is, there are defibrating material MB in roller portion 41, Humidity detected by first temperature humidity test section 323 and a reference value are comparably low humidity, and fibre length is shorter than a reference value The case where.The acceleration time of 5th velocity conditions is longer compared with whole acceleration time of first to fourth velocity conditions.? When at the time of speed VB reaching target velocity V1 under the 5th velocity conditions relative to any one of first to fourth velocity conditions Carve and rearward.

By this method, control unit 150 is interim in the amount of the first screening object MC dropped on reticular zone 46 from roller portion 41 In the case where becoming more, changed by way of increase speed, to inhibit the The variation of the thickness of one tablet W1.Moreover, by the humidity according to detected by the first temperature humidity test section 323 or by defibering Material fibre length, and make to make to roll (in other words, when the starting of the first sieve motor 40a) in the starting in roller portion 41 The mode that the speed of canister portion 41 rises changes, so as to further suppress the first tablet W1 thickness variation.As a result, thin In the process that piece manufacturing device 100 manufactures thin slice S, it can make in the process compared with the first tablet forming portion 45 rearward In be supplied to first screening object MC amount stablize, so as to inhibit thin slice S quality variation.Therefore, it can reduce use In the burden of the artificial adjusting work of the variation for the quality for inhibiting thin slice S.

Fig. 9, Figure 10, Figure 11 and Figure 12 are to indicate the thickness of the movement speed VB and the first tablet W1 in roller portion 41 The exemplary chart of variation, and show the example in the case where setting to the second to the 5th velocity conditions.In these figures In, (1) indicates the speed VB detected by the first sieve speed detecting portion 321, and (2) indicate to be examined by first thickness test section 324 The thickness of the first tablet W1 measured.The longitudinal axis, horizontal axis, target velocity V1, thickness TH1, TH2, moment T1 in these each figures is equal It is common with Fig. 8.In addition, in order to be compared, and illustrating moment T2 shown in Fig. 8 in these each figures.

Fig. 9 is the example for changing speed VB periodically, especially, shows showing of changing with making speed VB two stages Example.Control unit 150 is provided with before speed VB is accelerated to target velocity V1 to be comparably in low speed with target velocity V1 Between speed V2 come during maintaining.Specifically, control unit 150 is open the rotation of the first sieve motor 40a at moment T1 Begin, the mode for making speed VB reach midrange speed V2 at moment T3 is accelerated.Control unit 150 speed VB to be maintained in Between speed V2 until moment T4, and make the first further speedup of sieve motor 40a from moment T4, and at moment T5 The mode for reaching target velocity V1 is controlled.

In the example of figure 9, T5 is compared with T2 at the time of above-mentioned and rearward at the time of speed VB reaches target velocity V1.? That is control unit 150 after the rotation for starting the first sieve motor 40a, in a period of moment T1~T5, maintains speed VB is lower than the state (speed V2) of target velocity V1.As shown in Fig. 9 (2), although the detected value of first thickness test section 324 from when It carves to rise near T2 and change, but the peak value TH3 of the thickness of the first tablet W1 is less than the peak value TH2 of thickness shown in Fig. 8.Cause This, it is suppressed that the variation of the thickness of the first tablet W1 was apparent.

Figure 10 is the example for making speed VB phasic Chang, and especially, showing makes speed VB showing in three phase changes Example.Control unit 150 is provided with before making speed VB accelerate to target velocity V1 to be comparably in low speed with target velocity V1 Between speed V4 and midrange speed V5 come during maintaining.Specifically, control unit 150 makes the first sieve motor at moment T1 The rotation of 40a starts, and is accelerated in a manner of making speed VB reach midrange speed V4 at moment T11.Control unit 150 with Speed VB is maintained midrange speed V4 until moment T12, and keeps the first sieve motor 40a further from moment T12 Speedup, the mode that midrange speed V5 is reached at moment T13 are controlled.Control unit 150 is so that speed VB is maintained intermediate speed V5 is spent until moment T14, and makes the first further speedup of sieve motor 40a from moment T14, is reached at moment T15 The mode of target velocity V1 is controlled.

In the example in Figure 10, T15 is compared with T2 at the time of above-mentioned and rearward at the time of speed VB reaches target velocity V1. That is, control unit 150 after the rotation for starting the first sieve motor 40a, maintains speed in a period of moment T1~T15 Spend the state that VB is lower than target velocity V1.

As shown in Figure 10 (2), although the detected value of first thickness test section 324 changes near moment T11, The peak value TH4 of the thickness of first tablet W1 is less than the peak value TH2 of thickness shown in Fig. 8.Especially, at the first screening object MC After the roller portion 41 that drop amount is easy to increase just starts rotation, setting is successfully passed through with the substantially low speed compared with the target velocity V1 Midrange speed V4 is come (moment T1~T12) during being rotated, to inhibit lower the peak value TH4 of thickness.

As Fig. 9 and example shown in Fig. 10, control unit 150 can be such that speed VB periodically changes, speed VB Stage quantity or midrange speed can arbitrarily change.For example, it is also possible to change speed VB tetra- more than the stage.

Figure 11 indicates the example for making speed VB linear change.Control unit 150 accelerates to speed VB linearly from speed 0 Until target velocity V1, T21 is later than moment T2 at the time of so that speed VB is reached target velocity V1.That is, being the acceleration time The longer example compared with period TE1 (Fig. 8).As shown in Figure 11 (2), the peak value TH5 of the thickness of the first tablet W1 is less than Fig. 8 institute The peak value TH2 of the thickness shown, to successfully inhibit the variation of the thickness of the first tablet W1.

In the example of fig. 11, the control of the first sieve motor 40a implemented by control unit 150 is relatively simple.Therefore, With the setting for being easily managed various data and condition for being controlled the first sieve motor 40a or adjust more simple Single etc. advantage.

Figure 12 indicates the example for changing speed VB non-linearly.Control unit 150 is accelerate to speed VB from speed 0 In a period of until target velocity V1, it is changed acceleration, and so that speed VB is reached target velocity V1's at moment T31 Mode controls the first sieve motor 40a.

Specifically, including the first movement and second acts, and first movement is just to start to rotate it at moment T1 Afterwards, reduce acceleration, hereafter, the movement for time going by increasing acceleration, second movement is, with speed VB makes the movement of acceleration reduction close to target velocity V1.

In the illustration in fig 12, due at the time of speed VB reaches target velocity V1 T31 be later than moment T2, when accelerating Between it is longer compared with period TE1 (Fig. 8).Further, since the variation of the acceleration of the change rate as speed VB is more smooth, because This inhibits the variation to the power applied of the defibrating material MB inside roller portion 41.Therefore, can expect to decline to from roller portion 41 The first screening object MC amount the effect that is inhibited of variation.As shown in Figure 12 (2), the peak value of the thickness of the first tablet W1 TH6 is less than the peak value TH2 of thickness shown in Fig. 8, to successfully inhibit the variation of the thickness of the first tablet W1.

Second to the 5th velocity conditions can be using each example shown in Fig. 9~Figure 12.For example, can be in the second to the 5th speed Two stage acceleration mode shown in Fig. 9 is applied in the full terms of degree condition.In this case, the second to the 5th velocity conditions It is set to, at the time of T5 becomes different at the time of speed VB reaches target velocity V1.In addition, as shown in figure 9, second to the 5th Velocity conditions also may include the various parameters for changing speed VB.

In addition, the mode of the variation of the speed VB under the second to the 5th velocity conditions can also be not common.For example, second May be to the 5th velocity conditions, in a manner of shown in Fig. 9~Figure 12 in different modes make speed VB change condition.

Although in addition, speed VB is maintained solid after reaching target velocity V1 in the example shown in Fig. 9~Figure 12 It is fixed, but in the manufacturing process of thin slice S, speed VB can also be not fixed at target velocity V1.For example, also can be with thin slice S Manufacturing condition or the action state of sheet producing device 100 be correspondingly changed speed VB.

In addition, being controlled as corresponding with the humidity detected, can also be detected according to when defibrating processing portion 101 stops The humidity that humidity and defibering processing unit 101 out detects after restarting as a result, and implement determine compared with target velocity V1 For the control of the midrange speed V2 of low speed.

As discussed above, the sheet producing device 100 for applying first embodiment of the invention has pair As the roller portion 41 screened the first screening object MC for wrapping fibrous material and make the first sieve being discharged from roller portion 41 The reticular zone 46 for selecting object MC to accumulate.Sheet producing device 100 has as to the first screening object MC being deposited on reticular zone 46 Each portion of the manufacturing department 102 for the processing department processed.In the movement manufactured to thin slice S, i.e. in the implementation of processing, with Target velocity V1 and act roller portion 41, and in the case where the status triggering stopped from roller portion 41, implementation includes Back roll portion 41 is started in roller portion 41 with the starting movement of the state acted with the relatively low low speed of target velocity V1. Here, processing department may be any one in process compared with the first tablet forming portion 45 rearward, for example, making from constituting It makes in each portion in portion 102 and arbitrarily selects.

According to the first embodiment party of the control method for applying fiber processing device and fiber processing device of the invention The sheet producing device 100 of formula, in the starting that the amount of a screening object MC mobile from from roller portion 41 to reticular zone 46 is easy to change When, can the movement speed to roller portion 41 be suitably adjusted.Thereby, it is possible to inhibit the variation of the amount of the first screening object MC. Therefore, because being able to suppress the variation of the thickness of the first tablet W1, therefore thin slice S is manufactured in sheet producing device 100 Process in, can make first be supplied in the process compared with the first tablet forming portion 45 rearward screen object MC amount it is steady Fixedization.For example, being able to suppress the variation of the quality of thin slice S, the artificial tune of the stable quality for making thin slice S can reduce Save the burden of work.

Sheet producing device 100 is in starting movement, by roller portion 41 to carry out with the relatively low low speed of First Speed The scheduled time of state maintenance of movement.For example, example as shown in figs. 9 to 12 is such, it can be by speed VB miss the mark The state of speed V1 maintains the longer time compared with period TE1 (Fig. 8).As a result, due in first declined from roller portion 41 Screening object MC amount be easy to increase timing under, make speed VB maintain on the relatively low low speed of target velocity V1, therefore The variation of the amount of the first screening object MC can be effectively inhibited.

In addition, sheet producing device 100 is maintained in starting movement with the movement speed in roller portion 41 with the predetermined time Being comparably the mode in the second speed of low speed with target velocity V1 acts roller portion 41.Second speed is for example in Fig. 9 Example in be equivalent to midrange speed V2, be equivalent to midrange speed V4, V5 in the example in Figure 10.In this case, by with Fixed speed lower than target velocity V1 maintains speed VB, so as to effectively inhibit from roller portion 41 to reticular zone 46 into The variation of the amount of the first mobile screening object MC of row.

In addition, sheet producing device 100 is maintained in starting movement with the movement speed in roller portion 41 with the predetermined time Mode as the state for being comparably low speed with First Speed changes the movement speed in roller portion 41.For example, such as Figure 11 In the case that example changes speed VB linearly or changes speed VB non-linearly, Maintain the state that speed VB is lower than target velocity V1.In this case, by be lower than the fixed speed of target velocity V1 come Speed VB is maintained, to restrained effectively the change for carrying out the amount of the first mobile screening object MC from roller portion 41 to reticular zone 46 It is dynamic.

In addition, in sheet producing device 100, in the state that defibrating material MB is present in roller portion 41, from roller portion 41 states stopped, which rise, to be implemented to start.In this case, above-mentioned starting movement is executed.As a result, by under roller portion 41 The amount of first screening object MC of drop is easy in the state of increase, controls speed VB, so as to effectively inhibit first Screen the variation of the amount of object MC.In addition, in the state that the amount of the first screening object MC declined from roller portion 41 is not easy variation, by In the common starting sequence of execution, therefore the reduction of the manufacture efficiency of thin slice S can be prevented.

Sheet producing device 100 has the control unit 150 controlled the movement in roller portion 41, and control unit 150 exists In the movement manufactured to thin slice S, act roller portion 41 according to target velocity V1.Control unit 150 is in roller portion After 41 start, move roller portion 41 with the predetermined time according to as the setting speed for being comparably low speed with target velocity V1 Make.Setting speed is for example equivalent to midrange speed V2 in the example of figure 9, be equivalent in the example in Figure 10 midrange speed V4, V5.In this case, it is controlled in a manner of the speed become speed VB lower than target velocity V1, so as to have Effect ground inhibits the variation that the amount of the first mobile screening object MC is carried out from roller portion 41 to reticular zone 46.

In addition, sheet producing device 100 has the first temperature humidity test section 323 detected to humidity.Control unit 150 control setting speed according to the information of the humidity detected by the first temperature humidity test section 323.Therefore, energy The variation of the amount of the first screening object MC as caused by the variation of humidity is enough dealt adequately with, and the first screening can be effectively inhibited The variation of the amount of object MC.For example, as described above, the humidity in roller portion 41 is higher, then pass through the first screening object of opening 41a The variation of the amount of MC is fewer.In addition, when the humidity in roller portion 41 is lower, the fiber as included in the first screening object MC Electrification be difficult to be alleviated, therefore the agglutination of fiber is easy to largely generate, so the amount that the agglutination of fiber is disengaged is larger.Cause This, the humidity in roller portion 41 is lower, then the variation by the amount of the first screening object MC of opening 41a is bigger.For example, can In the case where detecting or deducing the humidity in roller portion 41 according to the detected value of the first temperature humidity test section 323, pass through Setting speed is controlled corresponding to the humidity in roller portion 41, the influence so as to deal adequately with by humidity causes First screening object MC amount variation.

In addition, roller portion 41 is cylindrical shape, and to be provided with opening on the circumferential surface in roller portion 41 and with the axis of cylinder Centered on and the structure that is rotated.Therefore, when in the inside in roller portion 41, there are make roller portion in the state of defibrating material MB When 41 starting, the amount of the first screening object MC dropped on reticular zone 46 at the start is easy to change.In this configuration, due to logical Cross the control of control unit 150 and during ensuring that roller portion 41 is rotated with the low speed lower than target velocity V1, therefore energy Enough inhibit the variation of the amount of the first screening object MC.

The sheet producing device 100 for applying fibrous raw material regenerating unit of the invention has defibrating unit 20, defibrating unit 20 As the miniaturization portion for making to wrap fibrous raw material MA miniaturization.Sheet producing device 100 have to by miniaturization portion by Roller portion 41 that the defibrating material MB of miniaturization is screened and as accumulating the first screening object MC being discharged from roller portion 41 The reticular zone 46 of accumulation portion.In sheet producing device 100, carried out as to the first screening object MC being deposited on reticular zone 46 The processing department of processing and each portion for having manufacturing department 102.In addition, sheet producing device 100 is in the manufacture of thin slice S, i.e., by In the execution for the processing that processing department is implemented, act roller portion 41 with target velocity V1.In sheet producing device 100 In, it is in roller portion 41 there are in the state of defibrating material MB, it is real in the case where the status triggering stopped from roller portion 41 It applies after being included in the starting of roller portion 41, roller portion 41 is dynamic with the starting for the state that the low speed lower than target velocity V1 is acted Make.According to this structure, by from roller portion 41 the first screening object MC carry out mobile amount be easy to change in the state of will rolling The speed of canister portion 41 is set below the low speed of target velocity V1, so as to inhibit the first screening object MC amount variation.

The mode for being in the first embodiment changed the speed VB in roller portion 41 is not defined to Fig. 9~Figure 12 Shown in example.For example, speed VB can also become the high speed higher than target velocity V1 after roller portion 41 starts.It is specific and Speech, control unit 150 or following mode, that is, accelerated in the case where roller portion 41 starts, until speed VB at Until for the high speed higher than target velocity V1, and maintain roller portion 41 with fast with target within the predetermined time after accelerating to finish The mode for the state that degree V1 different speed VB is acted.By this method, it in starting movement, can also execute including as follows First movement and second movement including movement, it is described first movement be to increase the acceleration in roller portion 41 together with the time Big movement, second movement are after by the time, to make the movement of the acceleration reduction in roller portion 41.At this In the case of, by keeping the variation of speed in roller portion 41 more appropriate, so as to keep the variation of amount of the first screening object MC flat It is slow.For example, by controlling in control unit 150 variation of the acceleration in roller portion 41, so as to inhibit because of roller The power of the variation of the acceleration in portion 41 and the defibrating material MB application into roller portion 41.In this case, can expect to make first Screen the gentle effect of the variation of the amount of object MC.

2. second embodiment

Hereinafter, being illustrated to second embodiment of the present invention is applied.

In the above-described first embodiment, to by starting acts drive control part 152 to the first sieve motor 40a Control is carried out to which the speed VB in roller portion 41 example being adjusted be illustrated.

Second embodiment controls the second sieve motor 60a in starting movement by drive control part 152 To be illustrated to the speed VD in roller portion 61 example being adjusted.In this second embodiment, roller portion 61 is equivalent to Sieve portion, the mixture M X being screened by roller portion 61 are equivalent to material, and reticular zone 72 is equivalent to accumulation portion.Second temperature Humidity detection unit 333 is equivalent to humidity detection unit.

The formation condition of the second tablet of 2-1.

Here, being said referring to Fig. 3 to the formation condition of the second tablet W2 formed in the second tablet forming portion 70 It is bright.

The thickness of second tablet W2 is from the amount of the mixture M X as the material supplied to reticular zone 72 and reticular zone 72 Amount of movement per unit time determines.The amount of movement per unit time of reticular zone 72 is speed VC.

It wants as determining the amount of mixture M X supply to reticular zone 72, pass through the amount of mixture M X of the 61a that is open Element can enumerate speed VD.Due to speed VD high speed, then roller portion 61 internal mix object MX promptly by Unlock, thus mixture M X it is easier pass through opening 61a.In addition, high speed, mixture M X are more easy to pass through opening speed VD 61a.Therefore, speed VD is faster, then the amount by the mixture M X of opening 61a is more.

It is changed by the amount of the mixture M X for the 61a that is open when roller portion 61 is started from halted state.In roller portion In 61, as making to generate friction included in mixture M X between fiber and fiber by the rotation in roller portion 61, Mixture M X can be charged.When being aggregated mixture M X because of the electrostatic, mixture M X will be difficult to through the 61a that is open.It is another Aspect, since the charge of the mixture M X of electrification is discharged, is wrapped in a period of roller portion 61 stops in mixture M X The agglutination of the fiber contained is disengaged.Therefore, when being rotated when roller portion 61 is since halted state, i.e., at the start, by opening The amount of the mixture M X of mouth 61a temporarily becomes more.

In addition, being influenced by the amount of the mixture M X of opening 61a by the humidity of the inside in roller portion 61.Here, wet Degree is referred to as relative humidity.When the humidity of the inside in roller portion 61 is lower, mixture M X electrification, to be easy to generate fibre The agglutination of dimension.Therefore, the humidity in roller portion 61 is lower, when rotating roller portion 61 is since halted state, that is, starts When, more it can temporarily become more by the amount of the mixture M X for the 61a that is open.

In addition, being changed by the length of amount fiber according to included in mixture M X of the mixture M X for the 61a that is open. Shorter fiber is easy to through the 61a that is open.Therefore, fiber included in mixture M X is shorter, then passes through the mixing of opening 61a The amount of object MX is more.

That is, determining that the maximum element of the amount of the mixture M X supplied from roller portion 61 to reticular zone 72 is roller portion 61 speed VD.In addition, roller portion 61 can be enumerated whether in starting as the element for changing the amount of mixture M X When, fiber included in the humidity in roller portion 61 and mixture M X length.

Control unit 150 implements the setting processing of Fig. 7 for speed VD.Control unit 150 is in the inside in roller portion 61 (step ST21) is judged with the presence or absence of mixture M X.The presence or absence of mixture M X, such as can also be according to by touch sensor 117 inputs implemented are judged.

It is being judged as (step ST21 the case where mixture M X is not present in the inside in roller portion 61；It is no) under, control unit 150 As the condition that the speed to the second sieve motor 60a is accelerated, and (step ST22) is set to First Speed condition, And end setup is handled.

(step ST21 the case where being judged as the inside in roller portion 61 there are mixture M X；It is) under, control unit 150 is right Whether the humidity as detected by the first temperature humidity test section 323 is more than a reference value included in benchmark Value Data 162 Judged (step ST23).Situation (step ST23 on the basis of humidity more than value；It is) under, control unit 150 is to mixture Whether the length of fiber included in MX more than a reference value included in benchmark Value Data 162 is judged (step ST24).The fiber as included in mixture M X is originated from raw material MA, the length with fiber included in defibrating material MB It is identical.

Situation (step ST24 on the basis of the length of fiber more than value；It is) under, control unit 150 is as to the second sieve The condition (step ST25) that the speed of motor 60a is accelerated, and second speed condition is set, and at end setup Reason.

In addition, in fiber (step ST24 the case where being shorter in length than a reference value；It is no) under, control unit 150 is as to second The condition (step ST26) that the speed of sieve motor 60a is accelerated, and third speed condition is set, and end setup Processing.

On the other hand, (step ST23 the case where humidity is lower than a reference value；It is no) under, control unit 150 is in mixture M X Whether the length for the fiber for being included more than a reference value included in benchmark Value Data 162 is judged (step ST27).

Situation (step ST27 on the basis of the length of fiber more than value；It is) under, control unit 150 is as to the second sieve The condition (step ST28) that the speed of motor 60a is accelerated, and fourth speed condition is set, and at end setup Reason.

In addition, in fiber (step ST27 the case where being shorter in length than a reference value；It is no) under, control unit 150 is as to second The condition (step ST28) that the speed of sieve motor 60a is accelerated, and the 5th velocity conditions are set, and end setup Processing.

First to the 5th velocity conditions are basic in the case where accelerating speed VD from zero when roller portion 61 starts Condition, target velocity including the second sieve motor 60a and the time until reaching target velocity or the second sieve motor The acceleration of 60a.

Control involved in the starting of speed VD can be using mode shown in Fig. 8~Figure 12.That is, by by Fig. 8~figure The speed VB as shown in (1) is set as the speed VD of the detected value based on the second sieve speed detecting portion 331 in 12 each figure, thus It can be handled as data relevant to the speed of speed VD.

Here, the target velocity V1 of speed VD both can be identical as the target velocity V1 of speed VB, or different Speed.

In addition, the acceleration time under the second to the 5th velocity conditions equally can be as the acceleration time relevant to speed VD To understand.The relationship of the length of acceleration time under each velocity conditions is also the same as the above first embodiment.

In this second embodiment, make to decline from roller portion 61 to reticular zone 72 in the control by control unit 150 In the case that the amount of mixture M X temporarily becomes more, speed VD when by starting to roller portion 61 is controlled, to inhibit The variation of the thickness of second tablet W2.As a result, in the process that sheet producing device 100 manufactures thin slice S, it can make The amount for the mixture M X being supplied in the process compared with the second tablet forming portion 70 rearward is stablized, and is able to suppress thin slice S Quality variation.For example, can reduce the negative of the artificial adjusting work inhibited for the variation of the quality to thin slice S Load.

The first to the 5th velocity conditions for being set for speed VD can also with illustrate in the first embodiment First to the 5th velocity conditions are identical, but the movement for roller portion 61 also can be used and implement optimized first to Five velocity conditions.

As discussed above, the sheet producing device 100 for applying second embodiment of the present invention has pair The roller portion 61 and make the mixture M X heap being discharged from roller portion 61 that mixture M X as the material for including fiber is screened Long-pending reticular zone 72.Sheet producing device 100 has as the processing department processed to the material being deposited on reticular zone 72 Manufacturing department 102 each portion.In sheet producing device 100, in the movement manufactured to thin slice S, roller portion 61 is with speed Degree VD (First Speed) is acted, and in the case where the status triggering stopped from roller portion 61, implementation is included in roller portion 61 After starting, with the starting movement for the state that the low speed lower than First Speed is acted.Here, processing department may be and second Tablet forming portion 70 is compared to any one in process rearward, for example, forming section 80 or cutting portion 90.
