Above-mentioned display elements are printed onto on continuous leakage prevention sheet 102 repeatedly.In other words, with length L2 pitch, typographical display is first repeatedly
Element.
But because leakproof plate substrate 100 is rolled up on spool, so the leakproof chip base of the radially inner side positioned at spool
Material 100 is wound by consolidation, and the leakproof plate substrate 100 positioned at radial outside is wound with being relaxed.Consequently, it can happen segmentation is single
Bit length (pitches of display elements) is in the radially inner side phenomenon different with radial outside.That is, leakproof plate substrate 100 is somewhat stretched
Contracting, its telescopic level is different with radial outside in radially inner side, so there occurs above-mentioned this phenomenon.
In addition, not being the state on spool in leakproof plate substrate 100, but continuously it is released and conveys from spool
When, it can also produce above-mentioned this phenomenon.I.e., now, leakproof plate substrate 100 is accelerated or slows down, so to leakproof plate substrate 100
Drag force it is different because of the acceleration or deceleration.Particularly, the leakproof plate substrate 100 in volume on spool is used up and just changed
Into after new leakproof plate substrate, the state of self-stopping technology accelerates to leakproof plate substrate 100 suddenly, so being applied with stronger pulling
Power.So, because unit length (pitches of display elements) can also occur to split for the acceleration or deceleration of leakproof plate substrate 100 because of place
Different and different phenomenon.
The appearance of leakproof plate substrate 100 when in Fig. 6 upper figure representing that above-mentioned phenomenon does not occur.In the leakproof plate substrate
On 100, segmentation unit length, the pitch of display elements are fixed (length L2) in any place.In addition, in order that figure simplifies
To facilitate explanation, display elements are represented with the bullet of the central portion positioned at segmentation unit and double circles of open circles.
On the other hand, represent that there occurs the appearance of the leakproof plate substrate 100 during the phenomenon in Fig. 6 figure below.It is anti-at this
On dropping fraction base material 100, the pitch for splitting unit length and display elements gradually increases from right to left.In addition, display elements are in itself
And from right to left, increase relative to deviation when above-mentioned phenomenon not occurring.In addition, Fig. 6 is the mental map understood for convenience,
It is different from the appearance of reality.
Here, as represented in above-mentioned example, when being cut to continuous leakage prevention sheet 102, continuous leakproof
The length from front end E1 to cutting position on the conveying direction of (clearance G) of piece 102 needs to reach defined length, i.e. needs
Reach the length L2 of the leakage prevention sheet 23 in 1 sheet articles (diaper 1).Thus, in the case where above-mentioned phenomenon does not occur, in order to reach
Length L2, the first delivery section 54 (the 3rd delivery section 58) of setting is to the transporting velocity of continuous leakage prevention sheet 102.It is for example, false
If transporting velocity is at the uniform velocity, in the situation that the time after continuous leakage prevention sheet 102 is cut untill cutting next time is the T seconds
Under, transporting velocity is set as L2/T.
But in the case of there occurs above-mentioned phenomenon, if enter to exercise the past end E1 to clearance G be always length L2 that
The conveying of sample, then as shown in the arrow upward of Fig. 6 figure below, it can no longer carry out appropriate cutting.
So, in the present embodiment, runout information obtaining section is (in the present embodiment by above-mentioned video camera 72 and above-mentioned
Controller 70 is formed) runout information that display elements deviate from reference position is obtained, the runout information based on acquirement changes first
Transporting velocity of the delivery section 58 of delivery section 54 and the 3rd to continuous leakage prevention sheet 102.
The flow chart of reference picture 7 illustrates.First, above-mentioned video camera 72 shooting display elements are utilized on defined opportunity
(step S1).The entirety of display elements can be shot, a part for display elements can also be shot.Here, based on will be located at point
The bullet for cutting the central portion of unit illustrates as the example of reference object.In addition, as the opportunity, as long as periodicity
(fixed) opportunity, as one, following example can be enumerated, i.e. be provided for cutter 61a close to above-mentioned
The proximity transducer that gap G etc. situation is detected, the signal based on the proximity transducer are shot.In addition, runout information
Obtaining section (video camera 72) as shown in figure 3, be pointed to continuous leakage prevention sheet 102 with the first delivery section 54 (that is, ribbon conveyer)
Display elements on the part of contact are detected.
Then, shooting result (display elements photographed) is output to controller 70 (step S3) by video camera 72, control
Device 70 analyzes image (step S5).Also, controller 70 obtains display elements (bullet) from benchmark position by the analysis of image
Put (that is, do not occur display elements (bullet) during above-mentioned phenomenon should position) runout information (step S7) that deviates.At this
In embodiment, obtain when conveying direction is set as into just (+) direction, display elements (bullet) exist relative to reference position
How many (biases) is deviate from+(-) direction, is used as runout information.
Then, controller 70 is based on the runout information obtained by runout information obtaining section, change the first delivery section 54 and
Transporting velocity (step S9) of 3rd delivery section 58 to continuous leakage prevention sheet 102.In addition, by the transporting velocity of the first delivery section 54 and
The transporting velocity of 3rd delivery section 58 controls as same speed all the time.
For example, when display elements (bullet) deviate from a amount relative to reference position on-direction (than benchmark position
Put situation about delaying), the first delivery section 54 (the 3rd delivery section 58) is set into (rising) to the transporting velocity of continuous leakage prevention sheet 102
To make the length from front end E1 to cutting position on the conveying direction of (clearance G) of continuous leakage prevention sheet 102 reach L2+a.For example,
Assuming that transporting velocity is at the uniform velocity, in the situation that the time after continuous leakage prevention sheet 102 is cut untill cutting next time is the T seconds
Under, transporting velocity is set as (L2+a)/T.On the contrary, display elements (bullet) relative to reference position on+direction partially
During amount from a (situation about shifting to an earlier date than reference position), by the first delivery section 54 (the 3rd delivery section 58) to continuous leakage prevention sheet 102
Transporting velocity set (decline) as, make continuous leakage prevention sheet 102 from front end E1 to cutting position on the conveying direction of (clearance G)
Length reach L2-a.
In addition, in this example, the bias a of acquirement and the amount a added and subtracted with L2 phases are set as identical value, but the present invention
This is not limited to, both can also be set as different amounts.
In addition, as runout information, the example for obtaining bias has been enumerated, but bias can not also be obtained, but only
Only obtain be+or-(be in advance or delay) information.Also, at this point it is possible to+in the case of, fixation is cut from L2
Value (the same value) ,-in the case of, to L2 plus fixed value (the same value).
Alternatively, it is also possible to bias a given thresholds, in the case of more than threshold value, be added or subtract each other with L2.Separately
Outside, the average value for the bias that can also be obtained over several times, based on the average value tried to achieve, it is added or subtracts each other with L2.
It is also, continuous with revised length (such as L2+a or L2-a) cutting when cutter 61a reaches the clearance G
Leakage prevention sheet 102, generate individual leakage prevention sheet 104 (step S11) corresponding with the variation of segmentation unit length.
Conveying on the second delivery section 56 controls
Conveying on the second delivery section 56 controls, and illustrates comparative example first, then puts off until some time later bright example of the present invention.
Comparative example
Second delivery section 56 conveys leakproof plate substrate 100 along conveying direction, as described above, being arranged on elastic adjustment unit 64
The upstream side of (elastic adjustment portion 65) and close to the front side of the elastic adjustment unit 64, the second delivery section 56 and elastic adjustment unit
64 act synergistically and control the tension force (tension) of leakproof plate substrate 100.That is, the positional information of elastic adjustment unit 64 obtains
Portion 66 (position-detection sensor) exports to controller 70 positional information of acquired elastic adjustment portion 65 on defined opportunity.
Also, controller 70 changes transporting velocity of second delivery section 56 to continuous leakage prevention sheet 102 based on the positional information.For example, control
Device 70 processed changes above-mentioned transporting velocity so that elastic adjustment portion 65 is located at defined reference position.Elastic adjustment portion 65 be located at than
In the case of the high position in reference position, transporting velocity is set to increase, so that elastic adjustment portion 65 declines.On the contrary, in elastic regulation
In the case that portion 65 is located at the position lower than reference position, decline transporting velocity, so that elastic adjustment portion 65 rises.Thus,
The tension force (tension) of leakproof plate substrate 100 can be controlled.
Example of the present invention
In a comparative example, controller 70 changes the first delivery section based on the runout information obtained by runout information obtaining section
54 and the 3rd delivery section 58 to the transporting velocity of continuous leakage prevention sheet 102, but the second delivery section 56 is not carried out to be based on the deviation
The control of information.
In this case, such as being based on runout information in controller 70 makes the first delivery section 54 and the 3rd delivery section 58 right
When the transporting velocity of continuous leakage prevention sheet 102 rises, elastic adjustment portion 65 is gradually increasing, so above-mentioned tension force (tension)
Control (that is, make the second delivery section 56 transporting velocity rise so that elastic adjustment portion 65 decline control) play a role.Separately
On the one hand, first delivery section 54 and the 3rd delivery section 58 are made to continuous leakage prevention sheet 102 based on runout information in controller 70
When transporting velocity have dropped, elastic adjustment portion 65 is gradually reduced, so the control of above-mentioned tension force (tension) (that is, makes second
The transporting velocity of delivery section 56 declines so that the control that elastic adjustment portion 65 rises) play a role.
But in this control, there are the following problems, i.e. changes the first delivery section from controller 70 based on runout information
54 and the 3rd delivery section 58 to changing the in order to control tension force (tension) after the transporting velocity of continuous leakage prevention sheet 102
Untill the control of the transporting velocity of two delivery sections 56 plays a role, the time is expended, the fast-response of control is not sufficiently good.
So, in the present embodiment, controller 70 is based not only on the positional information of elastic adjustment portion 65, is also based in addition
Runout information changes transporting velocity (step S9) of second delivery section 56 to continuous leakage prevention sheet 102.For example, in display elements
When (bullet) deviate from a amount relative to reference position edge-direction, controller 70 not only makes the first delivery section 54 and the 3rd
Delivery section 58 rises to the transporting velocity of continuous leakage prevention sheet 102, and makes conveying of second delivery section 56 to continuous leakage prevention sheet 102
Speed similarly rises (such as rising a/T amount).On the other hand, display elements (bullet) relative to reference position along+
When direction deviate from a amount, controller 70 not only makes the first delivery section 54 and the 3rd delivery section 58 to continuous leakage prevention sheet 102
Transporting velocity declines, and the second delivery section 56 is similarly declined the transporting velocity of continuous leakage prevention sheet 102 and (such as decline a/
T amount).In addition, the conveying control of the second delivery section 56 based on positional information is performed in the same manner as comparative example.
When so arranged, controller 70 can make the first delivery section 54 and the 3rd delivery section 58 to continuous leakage prevention sheet
102 transporting velocity rises the opportunity of (decline), the transporting velocity of the second delivery section 56 is risen (decline).Therefore, compared with
Example is compared, it is possible to increase conveys the fast-response of control.
On the shearing device of present embodiment and the validity of conveyance control method
In the present embodiment, controller 70 is believed based on the runout information obtained by runout information obtaining section and by position
The positional information that obtaining section 66 obtains is ceased, changes transporting velocity of second delivery section 56 to above-mentioned continuous sheet.
Therefore, as described above, it is possible to increase the fast-response of the conveying control of continuous leakage prevention sheet 102.
In addition, to convey this in the state of being contacted with continuous leakage prevention sheet 102 continuous for the first delivery section 54 of present embodiment
Leakage prevention sheet 102, runout information obtaining section be pointed to continuous leakage prevention sheet 102 (when obtaining runout information) with the first delivery section 54
Display elements on the part of contact are detected, so as to achieve runout information.
Runout information obtaining section can also be pointed to continuous leakage prevention sheet 102 not with it is aobvious on the part of any location contacts
Show that element is detected, but in this case, because continuous leakage prevention sheet 102 rocks, it is possible that can not precision well
Obtain runout information.On the other hand, in the present embodiment, the display elements on the part for the stabilization for being pointed to continuous leakage prevention sheet 102
Detected, thus can precision obtain runout information well.Therefore, also can precision carry out continuous leakage prevention sheet 102 well
Conveying control and cut-out.
In addition, in the present embodiment, as described above, runout information obtaining section (video camera 72) is pointed to continuous leakage prevention sheet
Display elements on 102 part contacted with the first delivery section 54 are detected, so the runout information obtaining section is with cutting
It is separated to cut roller 61.Thus, the segmentation unit in the continuous leakage prevention sheet 102 of the step S1 display elements photographed is printed with step
Rapid S11 is not to be cut and (turn into individual leakage prevention sheet 104 after step S11 cuttings), but in the conveying direction than the segmentation
(downstream) the segmentation unit of unit (for convenience of explanation, referred to as shooting segmentation unit) in advance (for convenience of explanation, is referred to as
Cut-out segmentation unit) turn into individual leakage prevention sheet 104.As described above, segmentation unit length is to change, but the change of the variation
Degree is generally slow, and the variation and the variation of cut-out segmentation unit of shooting segmentation unit are not significantly to change.Thus, even if should
It is inconsistent that unit is split in shooting segmentation unit and the cut-out, will not also produce problem (because not will be in 1mm also not
The extremely tight cut-out as wrong position is cut off is understood as target).But shooting segmentation unit and the cut-out
It is preferably as far as possible close to split unit.
So, in the present embodiment, it is ribbon conveyer to make the first delivery section 54.It is that belt is defeated in the first delivery section 54
In the case of sending machine, as shown in figure 3, the first delivery section 54 can be formed as to the elongated shape along conveying direction, so can make
First delivery section 54 (ribbon conveyer) is easily close to cutting roller 61.
Therefore, runout information obtaining section (video camera 72) also can close to cutting roller 61, so as to make shooting segmentation unit with
Cut-out segmentation unit approaches.Thus, it is possible to precision carries out the conveying control and cut-out of continuous leakage prevention sheet 102 well.
In addition, in the present embodiment, thus achieve：Make being contacted with ribbon conveyer from continuous leakage prevention sheet 102
Partial end E2 (reference picture 3) the leaning on to the part carried by anvil roller 62 using continuous leakage prevention sheet 102 by the side of cutting roller 61
The end E3 of belt conveying pusher side (is in the present embodiment, to be located to lean on the conveying direction upstream side position of some than above-mentioned clearance G
Position, reference picture 3 and Fig. 5) length in the conveying direction, it is more anti-than cutting individual that obtain after continuous leakage prevention sheet 102
The full-length (that is, length L2 when above-mentioned phenomenon not occurring) of dropping fraction 104 is small.
Accordingly, it is capable to make runout information obtaining section (video camera 72) close to cutting roller 61, so as to make shooting segmentation unit with
Cut-out segmentation unit approaches.Thus, it is possible to precision carries out the conveying control and cut-out of continuous leakage prevention sheet 102 well.
In addition, in the present embodiment, equally realize：Make the detected component (video camera from continuous leakage prevention sheet 102
72) the position D (reference picture 3) of detection leans on belt conveying pusher side to the part carried by anvil roller 62 of continuous leakage prevention sheet 102
E3 length in the conveying direction is held, than the full-length for cutting individual leakage prevention sheet 104 obtained after continuous leakage prevention sheet 102
(that is, length L2's when above-mentioned phenomenon not occurring) is 2 times small.
Accordingly, it is capable to make runout information obtaining section (video camera 72) close to cutting roller 61, so as to make shooting segmentation unit with
Cut-out segmentation unit approaches.Thus, it is possible to precision carries out the conveying control and cut-out of continuous leakage prevention sheet 102 well.
In addition, in the present embodiment, runout information obtaining section (when obtaining runout information) is set for 72 pairs using video camera
Display elements on continuous leakage prevention sheet 102 are shot, and runout information is achieved based on the display elements photographed.
Therefore, instant playback element is complicated, also can suitably obtain runout information.Thus, also can precision carry out well
The conveying control and cut-out of continuous leakage prevention sheet 102.
