Carrying device 21 has the rotary shaft 21a for capableing of rotatably supporting slice roller 5ar successively.Moreover, from that can send successively The elongation device 31 in downstream of the piece roller 5ar supported out from rotary shaft 21a on the direction MD sends out the continuous of back sheet successively Piece 5a.In addition, in this example embodiment, constituting are as follows: company of the above-mentioned rotary shaft 21a from the back sheet for being pulled and being conveyed by elongation device 31 Continuous piece 5a obtains rotary force, is integrally formed driven rotation with piece roller 5ar, but it is not limited to this.That is, can also be filled with by elongation The conveying movement driving rotary shaft 21a rotation in linkage for setting the serialgram 5a of the back sheet of 31 progress, alternatively, can also be such as Fig. 4 In hypothetically indicated with double dot dash line as, make to abut with the outer peripheral surface of piece roller 5ar and the drive of belt conveyor 23 that configures Dynamic spinning movement and above-mentioned conveying movement link, and the submitting successively which is supplied to serialgram 5a is handled.
Here, wind the serialgram 5a of the back sheet along continuous direction and before state as sheet above roller 5ar, such as Shown in Fig. 5, in advance in other factories etc., on the serialgram 5a of the back sheet, with defined pressroom on continuous direction Above-mentioned illustration IL, IL ... are printed with away from P5 (being equivalent to the second spacing).Moreover, print gap P5 is set as than the company in top flat The said goods spacing P3 set on continuous piece 3a small spacing.Therefore, in the above-mentioned engagement device 15 converged at the Pj of position, The serialgram 5a of back sheet is extended divided by elongation multiplying power Ms (=P3/P5) obtained from print gap P5 with product spacing P3 Under state, serialgram 5a is Chong Die with the serialgram 3a of top flat and fixed, to become as shown in Figure 3 in the serialgram 3a of top flat On appropriate location be configured with illustration IL state.
In addition, elongation multiplying power said here indicates on the continuous direction (direction MD) of the serialgram 5a under elongation state Overall length Lt extends to several times of the natural length Ln (external force do not act in the state of length) before elongation, for example, being capable of conduct Overall length Lt under elongation state is found out divided by division value obtained from natural length Ln (=Lt/Ln).
In addition, in this embodiment, in the case where print gap P5 is set as " 1 ", product spacing P3 is set as " 1.026 ", by This, the elongation multiplying power Ms of the serialgram 5a of the back sheet in engagement device 15 becomes 1.026 times.
Elongation device 31 makes the serialgram 5a of back sheet in the MD direction with defined elongation multiplying power Mt elongation, makes as a result, The deviation of the retractility of serialgram 5a smooths.Here, elongation multiplying power in the state of being extended using the elongation device 31 Mt is set as the elongation multiplying power Mt bigger divided by elongation multiplying power Ms (=P3/P5) obtained from print gap P5 than the said goods spacing P3 (> Ms), in this embodiment, it is set as 1.05 times.Therefore, on at least overleaf serialgram 5a of piece, in illustration IL, IL ... in the side MD In the range of the spacing arranged upwards becomes before product spacing P3, the deviation of above-mentioned retractility can be reduced.Moreover, as a result, The configuration of the illustration IL hereafter carried out in carrying device 51 can be performed with high precision, behind will be described.
In this embodiment, which uses tension controller 31.It is in chevron loop shape frame that tension controller 31, which has, If three rollers 31u, 31m, 31d of the serialgram 5a of back sheet, above three roller 31u, 31m, 31d are arranged in the MD direction.And And controlled with the controller appropriate such as sequencer (not shown) positioned at the roller 31u of the upstream side of roller 31m driving rotation Rotation is made, so that the tension of the serialgram 5a of the back sheet at the position of the roller 31m of middle in the MD direction becomes target value. For example, keeping the peripheral speed value (meter per second) of roller 31m bigger than current value, another party in the case where warp tension ratio target value is big Face keeps the peripheral speed value (meter per second) of roller 31m smaller than current value in the case where warp tension ratio target value is small.
In addition, the target value is set as value corresponding with the above-mentioned elongation multiplying power Mt that should be extended using elongation device 31.That is, The load-displacement curves of the serialgram 5a of back sheet can be measured in advance, then basis and the comparable displacement of elongation multiplying power Mt Corresponding load value finds out the target value.In addition, being provided on the bearing (not shown) of the roller 31m of middle (not shown) Load cell based on the measured value of the load from the load cell, can calculate the tension of the serialgram 5a of back sheet Value.Moreover, using the value of the tension of the calculating in the control of above-mentioned driving spinning movement.
In addition, substantially, making the serialgram 5a of back sheet on one side positioned at the roller 31u of upstream side in the example of the Fig. 4 The serialgram 5a of back sheet is sent out in elongation successively from the piece roller 5ar supported by carrying device 21 successively on one side.Therefore, for example Such earliest stage after just sending out successively, elongation device 31 can be such that the deviation of the retractility of serialgram 5a smooths, Thereby, it is possible to most effectively mitigate the adverse effect of the issuable deviation whenever elongation.
But, however it is not limited to this.As long as that is, the configuration of the elongation device 31 on the transport path of the serialgram 5a of back sheet The allocation position of position carrying device 21 successively more close than the allocation position of carrying device 51, it will be able to correspondingly enjoy from above-mentioned Smoothing effect from stage earlier.Thus, for example, the above-mentioned belt that can also be mainly abutted with the piece roller 5ar with Fig. 4 is defeated The serialgram 5a for sending machine 23 to send out back sheet successively, come replace mainly with the above-mentioned roller 31u of elongation device 31 from piece roller 5ar successively Send out the serialgram 5a of back sheet.
Here, it is preferable that can overleaf the elongation device 31 on the transport path of the serialgram 5a of piece and sending out fill It sets the position between 51 and the reliever 41 for mitigating the elongation state of serialgram 5a is set.I.e., it is possible to be configured to, with Billy The elongation multiplying power Mt of serialgram 5a in the state of being extended with elongation device 31 small mode, makes the elongation state of serialgram 5a It mitigates.Moreover, can then be effectively prevented from the reliever 41 as mitigated elongation state in such a way and be transported to submitting dress It sets during 51 a problem that issuable reduced width, longitudinal fold on serialgram 5a, turning back.In addition, from into one The step raising unfavorable condition prevents from the perspective of effect, it is preferred that is configured to, after being mitigated using reliever 41 The elongation multiplying power Mr of serialgram 5a is smaller than the elongation multiplying power Ms of the serialgram 5a after being changed using carrying device 51, in this embodiment, It sets in such a way, specifically, elongation multiplying power Mr is set as 1.017 times.Moreover, from the viewpoint of identical, preferably , keep the transport-route length of the serialgram 5a of the back sheet after mitigating longer than the transport-route length before mitigating.Therefore, exist In the example, setting are as follows: configuration of the allocation position of the reliever 41 on the transport path of serialgram 5a than carrying device 51 It is located proximate to the allocation position of elongation device 31.
In addition, in this embodiment, which also in the same manner as above-mentioned elongation device 31, uses tension controller 41. Moreover, controlling the driving rotation of the roller 41u positioned at the upstream side of roller 41m with the controller appropriate such as sequencer (not shown) Rotation is made, so that the serialgram 5a of the back sheet at the position of the roller 41m of the middle in three rollers 41u, 41m, 41d is in the side MD Upward tension becomes target value.Moreover, because the control mode is identical as above-mentioned elongation device 31, so the description thereof will be omitted.
What carrying device 51 converged to the processing system L3a of the serialgram 3a with top flat converges position Pj submitting back sheet Serialgram 5a.Moreover, carrying device 51 is with the illustration IL of the serialgram 5a of back sheet with the said goods spacing P3 in the submitting Arrangement and illustration IL are located at the configuration target position of the illustration IL on the serialgram 3a according to the product spacing P3 top flat determined The mode set changes the elongation state of the serialgram 5a of back sheet in the MD direction, here, at this point, serialgram 5a is in such as Lower state: based on the elongation processing at above-mentioned elongation device 31, the deviation of the retractility on the direction MD is reduced.Specifically, On at least overleaf serialgram 5a of piece, the spacing that illustration IL, IL ... are arranged in the MD direction become product spacing P3 it In preceding range, the deviation of above-mentioned retractility is reduced.Therefore, the change that above-mentioned elongation state can be carried out with high precision, by This, can configure illustration IL in the configuration target position on the serialgram 3a of top flat with high precision.
In addition, in this embodiment, as shown in figure 4, being reduced to 1.017 times for multiplying power Mr is extended with above-mentioned reliever 41.Cause This, to when converging position Pj and sending out serialgram 5a, is increasing to 1.026 for the elongation multiplying power Ms of piece 5a with carrying device 51 Times.That is, the carrying device 51 extends serialgram 5a again.Then, along with this, elongation is handled again, piece 5a The deviation of retractility can further become smaller, this also contributes effectively to change elongation state with high precision with the device 51.
The rotation that the carrying device 51 for example includes a pair of of niproll 52a, 52b, a pair of of niproll 52a, 52b of control is moved The sensor 57 of the position of the illustration IL of the serialgram 5a of the controller 55 and detection back sheet of work.
A pair of of niproll 52a, 52b are able to rotatably be supported around rotary shaft C52a, C52b along the direction CD.And And each roller 52a, 52b obtain driving rotary force from the servo motor (not shown) as driving source, sandwich the company of back sheet on one side Continuous piece 5a rotates on one side, sends out serialgram 5a to converging position Pj as a result,.
Controller 55 controls the rotation of niproll 52a, 52b by the detection signal based on the illustration IL exported from sensor 57 Rotation is made, to change the elongation state of the serialgram 5a of the back sheet between niproll 52a, 52b and engagement device 15.
Sensor 57 for example carries out image with filming apparatus 57c and to the image data sent from filming apparatus 57c The image processing apparatus 57ip of processing.For example with CCD camera, processor and memory, which for example claps filming apparatus 57c Take the photograph the serialgram 5a of back sheet on the move on the transport path between niproll 52a, 52b and engagement device 15.
Shooting action is carried out based on above-mentioned synchronization signal.That is, filming apparatus 57c receives synchronization signal always, when detecting The rotation angle value of the synchronization signal is consistent with the defined rotation angle value in the memory for being stored in advance in filming apparatus 57c When, filming apparatus 57c carries out shooting action.Rotation angle value as defined in above-mentioned, which is for example set as illustration IL, can be received in image data Value in the image of expression.Moreover, when the rotation angle value of synchronization signal is consistent with defined rotation angle value, shooting dress It sets 57c and shooting action is repeated.Therefore, in this embodiment, shooting action is carried out by illustration IL and generate image data.Moreover, Whenever generating new image data, the new image data is sent to image processing apparatus 57ip.
Image processing apparatus 57ip has processor and memory using computer appropriate as ontology.Whenever transmission comes from When the image data of filming apparatus 57c, image processing apparatus 57ip is based on the image data sent, as image procossing An example carries out binary conversion treatment.Moreover, extracting the photographing section of the illustration IL in the image of image data by binary conversion treatment Pixel and find out the position coordinates of the pixel.Details is as follows.
Firstly, the image of image data is by multiple pixel structures for two-dimensionally arranging on the two directions of x-direction and y-direction At.Moreover, shooting image for the direction MD as Y-direction for example using the direction CD as X-direction.In addition, image data and each pixel Accordingly it is respectively provided with colouring information.In this embodiment, since image data is tonal gradation, so only having for each pixel Brightness is as colouring information.In addition, indicating that the brightness of the pixel of illustration IL becomes the pixel than indicating the serialgram 5a of back sheet The low value of brightness.Therefore, if the pixel of brightness more than defined threshold value is distributed to white image and brightness is small Binary conversion treatment as black image is distributed in the pixel of threshold value, then the shoot part that can extract the illustration IL in image is allocated as For black image.Moreover, if the photographing section for extracting illustration IL can will constitute the whole of the black image as black image The arithmetic mean of instantaneous value of the position coordinates of pixel is used as the position for representing the position coordinates of the pixel of photographing section of above-mentioned illustration IL Coordinate.
On the other hand, in the above-mentioned memory of image processing apparatus 57ip, the position coordinates compared are previously stored with Data.Here, the position coordinates compared are expressed as follows position coordinates, i.e., converge position Pj above-mentioned, illustration IL just It really is configured in the case where configuration target position defined on the serialgram 3a of top flat, on this image the pixel of illustration IL The position coordinates that should be located at.In addition, the Y-coordinate in the position coordinates indicates the coordinate on the direction MD.
Therefore, image processing apparatus 57ip is capable of the value of the Y-coordinate of position coordinates based on this comparison and passes through two-value The difference of the value of the Y-coordinate of the position coordinates of the pixel of the photographing section of change processing extraction and the illustration IL found out, calculates illustration IL Offset in the MD direction.Moreover, believing whenever calculating the offset using the data of the offset of calculating as above-mentioned detection Number it is sent to above controller 55.
Then, spinning movement of the controller 55 based on data control niproll 52a, 52b.That is, indicating " to insert in the data Scheme upstream side offset of the IL on the direction MD " in the case where, the servo motor of the controller 55 control niproll 52a, 52b are put Big device 53a, 53b keep the peripheral speed value of niproll 52a, 52b amount of change Δ V more defined greatly than current peripheral speed value.This Outside, such as by defined gain multiplied by above-mentioned offset the amount of change Δ V of peripheral speed value is calculated.Then, pass through the circumference The change operation of velocity amplitude reduces the offset of illustration IL to the upstream side.
On the other hand, in the case where data indicate " downstream side of the illustration IL on the direction MD deviates ", controller 55 is controlled Amplifier 53a, 53b of the servo motor of niproll 52a, 52b processed make the peripheral speed value of niproll 52a, 52b than current Amount of change Δ V as defined in peripheral speed value is small.In addition, in this case, such as also by defined gain multiplied by above-mentioned offset And calculate the amount of change Δ V of peripheral speed value.Then, by the change operation of the peripheral speed value, reduce illustration IL downstream The offset of side.
Incidentally, in this embodiment, it is configured to carry out the change operation whenever sending above-mentioned data to controller 55. Moreover, as a result, all each sections that diaper will be become on the serialgram 5a of overleaf piece reduce with the tune of offset Whole, but it is not limited to this.For example, it is also possible to be configured to, to carry out primary ratio relative to multiple send, above-mentioned change is carried out Operation.
In addition, in this embodiment, as described above, by the serialgram 5a of the back sheet in the state of being extended using elongation device 31 Elongation multiplying power Mt be set as 1.05 times, as an example of the numerical value bigger than 1.026, described 1.026 be product spacing P3 divided by print The value that multiplying power Ms (=P3/P5) is extended obtained from brush spacing P5, but as long as meeting above-mentioned size relation, however it is not limited to This.In other words, as long as keeping above-mentioned elongation multiplying power Mt bigger than 1.0 times of the value of above-mentioned elongation multiplying power Ms, however it is not limited to this. It is preferable, however, that above-mentioned elongation multiplying power Mt can be set as to 1.01 times~2.0 times of the value of above-mentioned elongation multiplying power Ms, it is more excellent Choosing, can be set to 1.02 times~1.5 times of value.Moreover, can be based on if being set as being converged in such range The upper limit value of the range effectively inhibits the breakage of the serialgram 5a of back sheet, moreover, also can be based on the lower limit of the range Value, reliably equalizes the deviation of the retractility of piece 5a.
In addition, in this embodiment, as described above, the elongation multiplying power Mt at elongation device 31 is set as 1.05 times, but can referring to Fig. 4 Know, the value become back sheet serialgram 5a processing system L5a in back sheet serialgram 5a elongation multiplying power Mt, Mr, The maximum value of Ms.Therefore, following situation can be prevented trouble before it happens, i.e., causes this continuous by unnecessarily increasing elongation multiplying power The reduced width of piece 5a, longitudinal fold, the generation frequency for a problem that turning back are got higher.
Moreover, in this embodiment, the elongation multiplying power Mt at elongation device 31 is 1.05 times, it in contrast, will be in other factories In be printed with illustration IL the elongation multiplying power Mw that is assigned to the piece 5a when winding the state of roller 5ar in blocks of the serialgram 5a of back sheet It is set as 1.005~1.03 times smaller of range.That is, the elongation times in the state of being extended using elongation device 31 Rate Mt is bigger than the elongation multiplying power Mw of winding.
Therefore, can be made by the biggish elongation at the elongation device 31 since one side is with the elongation of the winding times Rate Mw elongation wind on one side roller 5ar in blocks state and place and the retractility of the serialgram 5a of issuable back sheet it is inclined Difference reliably equalizes.Moreover, as a result, carrying device 51 can to converge position Pj send out back sheet serialgram 5a When, the change of the elongation state of piece 5a is carried out with higher precision.
