The present invention completes in view of each problem above-mentioned just.Its object is to: provide one when thin
Material makes the transport path of thin material stablize and be prevented from occurring rolling bad when rolling between centers shifts
Wrap-up.
For solving the technical scheme of technical problem
For reaching above-mentioned purpose, it is a feature of the present invention that: to allowing thin material shift at rolling between centers
During be applied to the control aspect of the winding tension on the thin material of the Scroll rolling before being transferred and do
Improve.
Specifically, with following wrap-up as object, this wrap-up is comprising: utilize rotation dynamic
Make thin for the long ribbon shape transported continuously material is rolled into many Scrolls of cylindrical shape and described many rollings
Every Scroll in axle connects and drives the driving motor of this every Scroll, cut off by described thin material
Shut-off mechanism and be connected on described driving motor and described shut-off mechanism and working signal is defeated
Go out to described driving motor and the controlling organization of described shut-off mechanism, described thin material is being wound up into many
When on a spool in described Scroll, working signal is exported to allowing this rolling by this controlling organization
What axle rotated drives motor so that the winding tension being applied to described thin material is initial from set in advance
Value starts to reduce, and when rolling closes to an end, working signal is exported to allowing the next one by this controlling organization
Thin material is carried out rolling and not yet carry out rolling Scroll rotate driving motor to allow this still
Do not carry out the Scroll of rolling to start to rotate, and working signal is exported to described shut-off mechanism so that
Thin material between the described Scroll not yet carrying out rolling and the Scroll carrying out rolling transports
Described thin material is cut off by direction upstream side, will start to enter with the described Scroll not yet carrying out rolling
During row rolling, working signal is exported to the Scroll rotation not yet carrying out rolling described in making by this controlling organization
Turn driving motor in case when starting described thin material is carried out rolling winding tension reach described initially
Value.Turn towards the Scroll not yet carrying out rolling from the Scroll carrying out rolling allowing described thin material
During shifting, the Scroll that working signal is exported to making to carry out rolling by described controlling organization revolves
Turn drives motor so that the winding tension being applied to described thin material rises to equal with described initial value
Or close to described initial value.In the present invention by the following technical solutions.
It is to say, in the invention of first aspect, allowing described thin material from the receipts carrying out rolling
During spool shifts towards the Scroll not yet carrying out rolling, described controlling organization is by working signal
Output gives the driving motor of the Scroll rotation making to carry out rolling to be applied to described thin material
Winding tension rises and equal with described initial value or close to described initial value.
The invention of second aspect is such, in the invention of first aspect, when from starting rolling to knot
After full-time at least 70% past used by bundle rolling, working signal is exported by described controlling organization
Give the driving motor that the Scroll carrying out rolling described in allowing rotates to be applied to described thin material
Winding tension rises while thin material is carried out rolling.
The invention of the third aspect is such, in the invention of first or second aspect, and this wrap-up
Including: make water loading water loading mechanism on the outer peripheral face of the described Scroll not yet carrying out rolling and
Pushing machine on the outer peripheral face of the Scroll not yet carrying out rolling described in being pressed to by thin material in transit
Structure, described controlling organization is connected with described water loading mechanism and described dipper crowding gear, make described thin
Expect from the described Scroll of rolling that carries out towards the described Scroll transfer not yet carrying out rolling
During, described controlling organization by working signal output feedwater attachment mechanism in case water loading described still
On the outer peripheral face of the Scroll not carrying out rolling, and working signal is exported to described dipper crowding gear with
Just the outer peripheral face towards the described Scroll not yet carrying out rolling pushes thin material in transit, work is believed
Number output to described shut-off mechanism so that by transit and not yet carry out rolling described in being pushed to
Scroll outer peripheral face on thin material cut off.
The effect of invention
In the invention of first aspect, because carrying out the Scroll of rolling only in the rolling that closes to an end
Time just make the winding tension of thin material increase, so winding tension change to the thin material being rolled
Do not result in the biggest impact, thus the rollings such as gauffer also would not be occurred bad.When thin material is in rolling
When between centers transfer, while the transfer of thin material, winding tension when starting rolling can reach to be previously set
Good initial value or the initial value being previously set close to this, therefore, it is possible to rolling when making beginning rolling
The bad minimizing of the rolling near Scroll that tension variation is caused.And, when thin material is at Scroll
Between transfer when, the winding tension being applied to carry out the thin material on the Scroll of rolling rises to thing
The initial value first set or the initial value being previously set close to this, so when thin material is at Scroll
Between transfer time deflector roll deflection change the least, the transport path of thin material would not change, thus
Just it is prevented from owing to the caused rolling that has greatly changed of the transport path of thin material is bad.
In the invention of second aspect, even if being applied to thin material in the Scroll carrying out rolling
Winding tension rises when closing to an end rolling, and its ascending amount is also will not be to by the thin material of rolling
In the range of impacting this, send out therefore, it is possible to be reliably prevented in the Scroll carrying out rolling
Raw rolling is bad.
In the invention of the third aspect, when thin material is when rolling between centers shifts, the most with pushing
Thin material is pressed to thin material under the state not yet carrying out on the Scroll of rolling with shut-off mechanism by mechanism
Cutting off, the thinnest material laterally can skid relative to Scroll because of impact when cutting off the most again, it is thus possible to
Enough prevent from misplacing in rolling initial stage take-up position.Because towards the Scroll not yet carrying out rolling
When pushing thin material, the coefficient of friction between outer peripheral face and the thin material of Scroll can be because water loading be being received
Reduce, so starting to be held by thin material when rolling on Scroll at thin material on the outer peripheral face of spool
Easily laterally skid relative to Scroll.Therefore, if as the invention of first aspect, allowing thin material
When the winding tension making thin material raises, thin material is cut off when rolling between centers shifts, receive
Volume tension force i.e. can disappear.Winding tension one disappears, and thin material will on thin material width repeatedly
Flexible while starting by rolling.But, even if thin material occurs the biggest on thin material width repeatedly
Flexible, thin material is also due to the existence of the water being attached on the outer peripheral face of Scroll is relative to Scroll
Outer peripheral face slide.The thinnest material just will not be there occurs the state of contraction on thin material width
By rolling.Its result is can be reliably prevented when starting rolling to occur rolling bad.

The the second driving motor 4 turned, in order to the winding tension T when starting described thin material W is carried out rolling
Reach described initial value T0.
Terminate when rolling and from rotary body 2, will be located in the receipts of the described first opposite side driving motor 3
After spool 22 is unloaded down, working signal is exported to making described rotary body by described control device 10
The 2 described first driving motors 3 rotated, in order to the side making way for this first driving motor 3 is right
Thin material W carries out the Scroll 22 of rolling and transfers to the described first opposite side driving motor 3.
Explain it follows that the rolling to thin material W carrying out described wrap-up 1 works.
First, as it is shown in figure 1, the Scroll 22 making way for the opposite side of the first driving motor 3 revolves
Turning, the winding tension T being applied to thin material W starts slowly to decline from the initial value T0 set in advance,
By this Scroll 22, thin material W is carried out rolling.
Then, when be positioned at the first driving motor 3 opposite side Scroll 22 from start rolling to knot
Bundle rolling used by All Time gone over 70% time, then make to be applied to the winding tension T of described thin material W
Slowly rise.
The Scroll 22 of rolling is carried out towards the receipts not yet carrying out rolling from allowing described thin material W
Spool 22 transfer during, make the winding tension T being applied to described thin material W slowly increase and with
Described initial value T0 is equal.
The side making way for the first driving motor 3, the Scroll 22 not yet carrying out rolling rotate, and
And utilize water loading device 9 to allow water loading on the outer peripheral face of this Scroll 22.
Afterwards, it is pressed to thin material W to rotate but not yet carries out the Scroll 22 of rolling with pushing roller 7
Outer peripheral face on, and thin material W is being pressed to not yet carry out the periphery of the Scroll 22 of rolling
And carrying out at the described Scroll 22 not yet carrying out rolling with shearing device 5 under state on face
Thin material W is cut off by the thin material carriage direction upstream side of the Scroll of rolling 22, and makes to start thin
When material W carries out rolling, winding tension T reaches described initial value T0.
Afterwards, from rotary body 2, will be located in the described first opposite side driving motor 3 and finished
The Scroll 22 of rolling is unloaded down, then allows rotary body 2 revolve turnback, makes way for described first and drives
The side moving motor 3 and the Scroll 22 having started to carry out thin material W rolling transfer to described first
Drive the opposite side of motor 3.
As it has been described above, by repeatedly carrying out above-mentioned work, it is not necessary to allow wrap-up 1 stop i.e. can
Utilize each Scroll 22 that thin material W is carried out rolling operation.
It follows that the experimental result after having done experiment with the wrap-up 1 of the present invention is explained.
Fig. 6 be with transverse axis as elapsed time, the longitudinal axis is the amount of crawling of thin material W and depicts
Curve chart, is to start after being attached to splicing tape not yet carry out on the outer peripheral face of Scroll 22 of rolling
Described thin material W is made to carry out the Scroll 22 of rolling towards not yet receiving under the method for rolling
Data when Scroll 22 transfer of volume.Should illustrate, with pushing roller 7 towards not yet receiving
Pushing thin material W on the Scroll 22 of volume is to be cut off laggard by shearing device 5 by thin material W just
Row.
D1 show set will cut off thin material W with shearing device 5 time by the receipts carrying out rolling
The winding tension T of the thin material W of spool 22 rolling is 40N/m, on the other hand, if just by thin
Material W uses after cutting off and not yet carries out the Scroll 22 of rolling by this thin material W rolled-up winding tension T
For result during 220N/m；D2 shows and is by before thin material W cut-out with shearing device 5
Or the most unrelated, will carry out the Scroll 22 of rolling and not yet carry out the Scroll 22 of rolling
Winding tension T result when being set to this certain value of 220N/m.
From the result of D1, if winding tension T changes a lot the most afterwards, that
After just being cut off by thin material W, thin material W has the biggest crawling, then the most wrong with take-up position
The state of position carries out rolling to thin material W, and Fig. 8 (a) is also shown for this situation.
From the result of D2, if making winding tension T the most afterwards for certain value, then
After just being cut off by thin material W, thin material W has the biggest crawling, and Fig. 8 (b) shows this situation.
But with make compared with winding tension T changes the biggest situation the most afterwards, what this was the biggest crawls at once
Will disappear, and take-up position can return to original position.
It is believed that occur that the reason of above-mentioned phenomenon has two.First, if thin material W will cut off
Time winding tension T relatively low, then the frictional resistance between deflector roll G3 and thin material W will be the lowest, thin
Material W laterally can skid by deflector roll G3 relatively due to impact when cutting off.Second, when thin material W's
Winding tension T from relatively low value towards higher value change time, the deflection of deflector roll G3 has the biggest
Change, the transport path of thin material W the most just there occurs change.
As Fig. 6, Fig. 7 be also with transverse axis as elapsed time, the longitudinal axis be the Serpentis of thin material W
The curve chart that row is measured and depicted.D3 is illustrated that, be by shearing device 5 cut off thin material W it
Front or the most unrelated, make carry out the Scroll 22 of rolling and not yet carry out the Scroll of rolling
The winding tension T of 22 be the such a definite value of 220N/m and when adhering to water by pushing away
Thin material W is pressed to not yet carry out proceeding by receipts on the outer peripheral face of the Scroll 22 of rolling by pressure roller 7
The result of volume.
From the result of D3, if winding tension T is certain value the most afterwards, and
Allow water loading rolling by the Scroll 22 not yet carrying out rolling when on outer peripheral face, then
The biggest crawling is produced after being prevented from just being cut off by thin material W.As shown in Fig. 8 (c), Bu Huifa
The raw rolling such as gauffer, take-up position dislocation is bad.
It is believed that occur that the reason of above-mentioned phenomenon has two.First, due to pushing roller 7 by thin material
W is pressed on the outer peripheral face of Scroll 22, and the thinnest material W will not be horizontal relative to Scroll 22
Skid.Second, even if winding tension T disappears when cutting off and causes thin material W at the width of thin material
Repeat on direction to stretch, thin material W also due to the existence of water and relative to the outer peripheral face of Scroll 22
Sliding, the thinnest material W would not be there occurs that the state of contraction is by rolling the most.
Should illustrate, if when thin material W is rolled onto on Scroll 22, to be applied to thin material W
The winding tension T mode that starts to be gradually lowered from the initial value T0 set in advance carry out rolling,
The deflection of deflector roll G1～G3 will change, the gradient of the rotary shaft on each deflector roll G1～G3,
Position can change respectively, and the transport path of thin material W will change, the most by cylindric ground
The thin material W being wound up on Scroll 22 end in the direction of the width is actually outside the closer to footpath
Side more gently bends, but this is not the biggest bending, is not that rolling is bad.Fig. 8 (a), figure
In 8 (b) and Fig. 8 (c) for convenience, illustrate with straight line rolling state.
As it has been described above, according to the embodiment of the present invention, in the Scroll 22 carrying out rolling,
The winding tension T making thin material W only rises when closing to an end rolling, the therefore change of winding tension T
Change not resulted in the biggest impact by the thin material W of rolling, gauffer etc. also would not be occurred to receive
Roll up bad.
When thin material W shifts between Scroll 22, it is possible to open while thin material W shifts
The state of initial value T0 that during beginning rolling, winding tension T reaches to be previously set starts to enter thin material W
Row rolling, therefore, it is possible to make near Scroll 22 due to start rolling time winding tension T change
The bad minimizing of rolling caused.And, when thin material W shifts between Scroll 22, apply
The winding tension T giving the thin material W on the Scroll 22 carrying out rolling can rise towards this thing
The initial value T0 first set, therefore the deflector roll G1-G3 when thin material W shifts between Scroll 22
Deflection change little, the transport path of thin material W will not change such that it is able to prevent due to
The transport path of thin material W changes greatly and causes rolling bad.
Even if the winding tension T being applied to thin material W in the Scroll 22 carrying out rolling exists
Close to an end rolling time rise, its ascending amount also will not to from described Scroll 22 start rolling to
Terminate All Time used by rolling to have gone over to be impacted this by the thin material W of rolling after 70%
In the range of, therefore, it is possible to be reliably prevented in the Scroll 22 carrying out rolling generation rolling not
Good.
When thin material W shifts between Scroll 22, the most using dipper crowding gear 7 by thin material W
It is pressed to not yet carry out being cut off by thin material W with shearing device 5 under the state on the Scroll 22 of rolling,
The thinnest material W laterally can skid relative to Scroll 22 because of impact when cutting off the most again, it is thus possible to
Enough prevent the location dislocation in the rolling of rolling initial stage.
In addition, because when pushing thin material W on the Scroll 22 not yet carry out rolling,
Coefficient of friction between outer peripheral face and the thin material W of Scroll 22 can be because being attached to Scroll 22
The water of outer peripheral face and reduce, so starting by thin material when rolling on Scroll 22 at thin material W
W slides easily with respect to Scroll 22.Therefore, if as the invention of first aspect, allowing
When thin material W shifts between Scroll 22, in the state making the winding tension T of thin material W raise
Lower by thin material W cut-out, winding tension T i.e. can disappear.This winding tension T mono-disappears, and thin material W is just
Can be while repeatedly stretching while starting by rolling on thin material W width.But, even if thin material
There is the biggest stretching in W on thin material W width, thin material W also due to be attached to repeatedly
The existence of the water on the outer peripheral face of Scroll 22 and slide relative to the outer peripheral face of Scroll 22, so
Thin material W would not be there occurs that the state of contraction is by rolling the most.Result is can
When being reliably prevented beginning rolling, rolling is bad.
Additionally, in embodiments of the present invention, rolling is being started to terminating rolling from Scroll 22
All Time used gone over 70% time, make the winding tension T being applied to thin material W slowly increase.
But be not limited to this, as long as starting rolling to terminating All Time used by rolling from Scroll 22
At least pass by just to make the winding tension T being applied to thin material W slowly increase after 70%.
In embodiments of the present invention, wrap-up 1 includes two Scrolls 22, but rolling
Device 1 can also include many Scrolls 22.
In embodiments of the present invention, allowing thin material W from the Scroll 22 carrying out rolling
Make to be applied to the winding tension of thin material W towards the Scroll 22 not yet carrying out rolling during shifting
T slowly rises and rises to equal with initial value T0.But not necessarily to make described winding tension T
Essentially equal with initial value T0, as long as making described winding tension T at the 80～120% of initial value T0
Between.
Additionally, in embodiments of the present invention, wrap-up 1 is used for carrying out with printer
The thin material W of printing carries out rolling.But this wrap-up can also be used to carrying out with coating machine
The thin material of coating carries out rolling.As long as the device present invention that thin material shape object is carried out rolling
It is all suitable for.
