Description

Yarn winding machine and method for coiling thereof

The present invention relates to Yarn winding machine and the method for coiling thereof of high-speed wind-up especially the sort of increase, the Yarn winding machine and the method for coiling thereof that dwindle by the space that turntable revolution can be made batch usefulness along with roll diameter from the spun yarn of spinning machine.

Known in the past the sort of turret type yarn reeler is on the rotating turntable of energy, the center of gyration of turntable be clipped in the middle ground, set two axles (being also referred to as the bobbin holding element) of batching usefulness in its both sides, axle can be distinguished driving independently, and plug-in mounting a plurality of bobbins on each axle; Side in above-mentioned two single mandrel is configured in roughly batching on the position of vertical top, the opposing party is configured on the position of readiness of vertical below roughly, Yarn reeling on the bobbin that is positioned at the axle of batching the position, when this bobbin becomes full volume package, make above-mentioned turntable return turnback, be suspended to and carry out on the bare bobbin that newly is in the axle of batching the position beginning new batching after the guide directing into the yarn that becomes in the full volume package.Like this, the Yarn reeling of supplying with continuously on two single mandrel.

But,, thereby the machinery of Yarn winding machine is highly increased because the position of batching above roughly vertical forms full volume package meeting the slip case of the member composition that keeps the touch roll that contacts rotationally with this package etc. is risen higherly.And; owing to make turntable revolution, make the package of satisfied volume forward in 180 degree and be in the roughly position of readiness of vertical below from the position revolution of batching that is in vertical top roughly; completely the package path of motion of retouching out along with the revolution of turntable can be outstanding significantly in the side of Yarn winding machine for this; thereby under the occasion that many Yarn winding machines are set side by side, the interval of every propulsion plant just must be obtained bigger.

At this problem, following scheme was proposed, promptly propose not the roughly vertical top of batching the center of gyration that locational axle is fixed on turntable, make the turntable rotating that part of increase that is equivalent to roll diameter downwards, make the Yarn winding machine and the method thereof of the position almost fixed of touch roll with replacing original axle with this.Because the position almost fixed of touch roll, thereby the rise height of slip case just reduces, the machinery of Yarn winding machine highly also just can correspondingly reduce.Again because along with the diameter from the bobbin of sky to completely package increases, is to carry out during making the downward turning course of turntable, thereby the above-mentioned path of motion of the package degree outstanding from the Yarn winding machine side is also little.

Again since be subjected to yarn from full package carry out the transition to the place restriction of blank coil dress and completely the place of the package position of doffing of taking off limit, the reel position of beginning the or completely position of package is improper, thereby the minimizing degree of the minimizing of the machinery height of Yarn winding machine and package path of motion amplitude is all insufficient.

But, as shown in figure 14, go up, can be provided with its layer surface free lifting and contact batching the bobbin of side (coiling package 101), thus the touch roll 102 that its contact pressure that applies regulation is used.In the past, for this contact pressure of cross-check sum correction, be the revolution of bobbin to be driven stop, this contact pressure of practical measurement, touch roll 102 being adjusted.The problem that the operation energy rate reduction that makes coiling process is arranged for this reason.Again since along with volume through increasing, will changing under the occasion of contact pressure, for example, hour contact pressure is increased when coil diameter; When coil diameter becomes big, makes under the occasion that contact pressure controls with reducing, can not carry out according to indirect indexs such as the times of batching, thereby the problem that can not carry out suitable control is arranged.Also because bobbin holding element 103 is to form overhanging supporting structure on the machine body side, when the weight of package 101 becomes big, deflection can takes place, front is descended (as the long and two-short dash line among the figure), this part decline reduces with regard to the contact pressure that makes touch roll 102.So, just variant with the contact pressure of the bobbin of base end side, the problem that can not form the uniform package 101 of quality is arranged.

The present invention makes for the problem that solves the prior art existence, its objective is provides a kind of Yarn winding machine and method for coiling thereof, it can not only reduce the machinery height of Yarn winding machine and the amplitude of package path of motion, and can smoothly successfully carry out the transition that yarn adorns to blank coil from full package and the full doffing operation of package.

Below, with reference to accompanying drawing embodiments of the invention are described.Fig. 1 is the front elevation of Yarn winding machine of the present invention, and Fig. 2 is the lateral plan of Yarn winding machine of the present invention.The structure of Yarn winding machine is described earlier.

In Fig. 1 and Fig. 2, Yarn winding machine 1, turntable 6 with respect to 26 one-tenth point-symmetric positions of center of gyration on, have plug-in mounting two of a plurality of bobbins (low pipe) in the axle 2,3 of drawing, make their high speed rotating respectively by spindle motors 4,5.Turntable 6 and bearing cartridge 7 can be maintained on the axle of being fixed on the machine body 89 pivotally.Turntable is being connected with bearing cartridge 7 with chain 12 by sprocket wheel 10,11 with motor (M1) 13.And, by turntable is controlled with the revolution of motor (M1) 13 position that is arranged on two single mandrel 2,3 on the turntable 6 highlightedly is on the assigned position.

Guide bar 14 uprightly is being set abreast, along this guide bar 14, can be provided with up and down and see slip case 15 on the side of machine body 8.This slip case 15 by and machine body 8 between the contact pressure cylinder 7 that is provided with supporting.Pneumatics by control feeding contact pressure cylinder 17 makes under the state of slip case 15 risings; Perhaps guarantee by following touch roll 16 forms package P is applied under the state that can follow package P when regulation connects pressure and move.The touch roll 16 see cross feed device 18 that the yarn bifurcation is traversed, to join from the yarn bifurcation of cross feed device 18 outputs is set on this slip case 15.The central authorities of the machine body 18 that guide bar 14 and contact pressure cylinder 17 are not put at base 19 are arranged on the position of departing from turntable 6 and intersecting with the axle of axle 2,3, and like this, the interference of center roller 2,3 and slip case 15 just is limited to minimum degree.

In Fig. 1, spindle motors (M2) 4 of drive spindle 2 and axle 3 usefulness and spindle motors (M3) 5, its revolution is detected by impulse deviser PG1, PG2, with controller 23 these two motors is controlled to the regulation revolution.Particularly, along with package is rolled into, roll diameter increases, the revolution of axle 2 is descended to some extent, at this moment, by controller 23 it is controlled to the yarn speed that obtains from the impulse deviser PG1 of touch roll 16 and is retained necessarily.In addition, and on the synchronously rotating part of turntable 6 coder 24 is installed, drives turntable with motor (M1) 13 according to the instruction of sequencer 21 outputs that link to each other with coder 24, the specified signal of slave controller 23 outputs is imported into sequencer 21.Make turntable 6 relative center of gyrations 26 forward predetermined angular ground to by turntable with the driving of motor 13 and become assigned position.

The position of this turntable 6 have the axle 2 that is under the state of batching at the stop position (the 1st position) of regulation the occasion of A and for making the axle 2 that is in the state of batching under along with thus the decline of the diameter increase of package P makes turntable 6 rotating positions (the 2nd position) B.When making turntable 6 turn round, make a side axle 2 to arrive C positions (the 2nd position) again, 3 of the opposing party's axles become the A position.Position A is the point above the horizon that is positioned at center of gyration 26 of turntable 6, and position B be angle beta from the B1 point to interval that B2 is ordered.Position A is but the rotary position of representing axle 2 be in center of gyration 26 roughly along Nogata to top (when promptly vertical top being taken as zero, be to locate for 0 °～20 °) in the cw revolution.Like this, the opposing party's axle 3 just is on the C position of vertical below roughly and since completely package P in the amplitude of machine body 8, thereby extraction with regard to doffing easily.And departing from the touch roll 16 that center of gyration 26 1 sides set and the bare bobbin of axle 2 is to be in the state that just in time joins.

The interval of the angle beta of position B is axle 2 that state is batched in the expression occasion of ordering to the B2 that roughly (vertical top is taken as zero, then changes 70 °～170 ° along cw) along straight below from the B1 point of the roughly positive side of center of gyration 26, be to represent the interval of mainly batching.In the little incipient stage of angle beta,, thereby can not give prominence to outside the amplitude of machine body 8 because the layer thickness of package P is 20mm at most.And when batching progress, though the diameter of package P becomes greatly, because turntable 6 revolutions make angle beta become big, thereby package P can not give prominence to outside the amplitude of machine body 8 yet.In order to reduce the outstanding of package P, must the B2 point when arriving completely package be set in below the horizon of the center of gyration 26 by turntable 6.When axle 2 was in the B2 point, touch roll 16 was on the B3 position, but for yarn is carried out the transition to the blank coil dress from full package, made touch roll 16 rise to the position of original B1.After this, make turntable 6 further turn round, when completely the axle 3 of package is in the C position, 2 of the axles of blank coil dress are on the A position.For the position B2 point that carries out B and the conversion of C position, both are configured in center of gyration 26 by turntable 6) the both sides of plumb line.By such processing, can guarantee the rising space of touch roll 16.

Below, explanation along with the increase of package P diameter, make turntable 6 rotating methods.In Fig. 1, the revolution of motor (M2) 4 that is in the axle 2 of the state of batching detects by impulse deviser PG2, confirms as axle revolution (ω) by controller 23.On the other hand yarn speed preestablished, by detecting, confirm as yarn speed (V) by controller 23 with the corresponding impulse deviser PRG1 of touch roll 16.Between this axle revolution (ω) and yarn speed (V), has relational expression: V=π * φ * ω (φ wherein is the diameter of package).From this relational expression, controller 23 is calculated the diameter (φ) of package.And, predefined roll diameter is made into chart and is stored in the controller 23, when the roll diameter of calculating is consistent with the diameter on the chart, signal in sequencer 21 outputs arteries and veins as shown in the figure.Whenever this impulse singla becomes the degree of cutting off or connecting, make turntable 6 revolutions on one side, for example be made into chart and the angle ground stored, confirm the output of coder 24 by sequencer 21, Yi Bian make motor (M1) driving.Thus, be made into chart by each and remember roll diameter in the storage storage of controller 23 and make turntable 6 revolutions.

The method of the roll diameter of growing sturdily in replaceable above-mentioned place, adopt following method, promptly, make yarn speed certain, utilize the certain relation that exists between time and winding diameter, turn round and look at earlier the rotating relational expression of time and turntable 6 be input to 23 li of controllers and time through turntable 6 is turned round.

Below, see figures.1.and.2, illustrate the overview of batching action that forms by above-mentioned Yarn winding machine.In Fig. 1, enter automatically yarn from before completely package P carries out the transition to batching continuously of bare bobbin, carry out guide.This guide operation is to carry out (step 2 in the 1st position that axle 2 becomes the A position ^#).Then, when guide finishes, the starting position B1 that axle 2 is in angle beta like that, the turntable clockwise direction is turned round.So following axle 2 ground, touch roll 16 drops to position B3 (step 3 ^#).

Then, along with package P diameter increases, make that axle 2 descends, touch roll 16 stops at above-mentioned position B3 and goes up (step 4 ^#).So the winding diameter of package P along with axle 2 downwards and increase, constitute the full volume package (step 5 of A6 to machine center ^#).According to, make turntable 6 turn round, make thus full volume package P to be in the AF position a little, meanwhile, axle 3 is in A position (step 6 ^#).Simultaneously, make touch roll 16 rise to axle 3 on the B1 position that joins of the bare bobbin of plug-in mounting, carry out yarn carries out the transition to bare bobbin from full package P action (step 7 ^#).Then, after the yarn transition, promptly the revolution of full volume package P is stopped, carrying out (the step 8 of doffing of full volume package P ^#).

By carry out step 3 repeatedly ^#～step 8 ^#, just can carry out batching of yarns Y continuously.

Below, with reference to Fig. 4,5 details of method for coiling is described.Fig. 4 (A) represents with the full volume package P shown in the long and two-short dash line by the step 3 after doffing ^# State.Axle 2 is fixed on the A position, before finish to doffing after the yarn transition, be that bare bobbin is batched, during this, diameter ground from A1 to A2 of package increases, thereby make touch roll 16 positions rise to the B2 position.

Fig. 4 (B) expression doff just finish the back, axle 2 to the B1 position to the step 3 of changeing ^#State.Turntable makes axle 2 become ground, a B1 position clockwise direction degreeof turn α from the A position.Touch roll 16 following axle 2 action, drop to the B3 position.

Fig. 4 (C) expression makes the rotating step 4 of turntable along with the increase of roll diameter ^# State.Touch roll 16 still stops on the B3 position, but axle 2 increases along with roll diameter and descend, and roll diameter a4 → a5 → a6 increases, becomes thus full volume package P.During this section, by the revolution of turntable, axle 2 from the B1 position to B2 position move angle β.This angle beta becomes with the full size of package P, but the starting position B1 of angle beta is certain.

Fig. 5 (a) expression completely package forms the back, makes a little rotating step 6 of turntable ^#State.Make a turntable degreeof turn γ, thereby make the opposing party's axle 3 be in the A position.Before this, connect touch roll 16 and rise, constitute yarn y through touch roll 16, slip over the top of empty tube and to the full path of package P.Completely package P continues revolution in the C position.

The step 7 of Fig. 5 (b) expression yarn transition ^#State.The yarn transition apparatus is at bare bobbin with completely pass in and out between the package P, Yi Bian yarn is not guided from full package P with coming off, is shifted Yi Bian yarn y is entered in the linear slit of bare bobbin.So, yarn y become trapped in the slit of bare bobbin, thereby the yarn transition is finished.After the yarn transition is finished, stop to be in the full volume package P revolution under the a7 state immediately, doff, be returned to the state shown in Fig. 4 (a) after stopping.

Illustrated in the above embodiments is the situation that a turntable, two single mandrel set with becoming point symmetry, but also can be on two turntables, respectively be provided with independently a single mandrel, each axle is moved independently, it is by above-mentioned axle being carried out in the revolution than the center of gyration downside of turntable, can making the position of batching the axle when finishing that becomes full volume package be in the place, roughly vertical below of the center of gyration of above-mentioned turntable that roll diameter becomes big most of process.

When carrying out Yarn reeling, as illustrated in fig. 12, earlier desired contact pressure setting value is input to 151 li of controllers by the adjustment revolution of bobbin holding element.Definite value of the desirable one-tenth of this setting value, also can make tool time dependent.For example can establish the program that increases, makes the contact pressure minimizing along with the coil diameter of package 101 of finishing.Then, begin to batch, detect contact pressures, this detected value is input to 151 li of controllers respectively by dynamometry pressure difference transmitter 124,137 by the revolution of spindle motors.Then, relatively detected value and setting value if having significant difference therebetween, are then regulated the vapour pressure of cylinder 150 by pressure regulating member (electromagnetic valve) is moved, thereby are made cylinder 150 carry out expanding-contracting action.Change the relative position of touch roll 102 and package 101 thus, adjust contact pressure by load change.

Then, along with the carrying out of batching, when the weight of package increased, the front of bobbin holding element can descend, and the contact pressure of front just becomes also littler than base end side, but this variation is picked up survey as the difference of the contact pressure value on two shaft ends 114,115.When the difference of this detection occurs, in order to eliminate this difference, make to adjust and do the elongation of small quantity or shrink back with 143 in cylinder, make touch roll 102 with elastic body 130 be fulcrum fascinate, form the state parallel, the front and back end contact pressure is equated mutually with the bobbin holding element.Then, cylinder 150 is driven.When carrying out this adjustment action, also can set the permissible range of the difference of both sides detected value, when surpassing this permissible range, make and adjust with cylinder 143 actions.

Like this, owing to be provided with the force transducer 124,137 of the contact pressure that can in coiling process, detect touch roll 102 continuously, again according to this value, touch roll 102 is fascinated or lifting by tilting equipment 144 and lifting mechanism 111, thereby do not need to make to batch and stop just can not survey contact pressure, can form the suitably control like that in addition of desired setting value.Promptly, can improve the work efficiency of coiling process, and can improve the quality of package 101.Again owing to force transducer 124,137 all is set in the base end side and the front of touch roll 102, even thereby contact pressure also can be adjusted accordingly with it immediately to difference axially occurring.Promptly, from coiling begin till full volume state, can both be controlled to the bobbin holding element can not produce bending, all form setting value, can produce the package uniform, attractive in appearance 1 that is provided with difference each goods.

Fig. 9 is expression the 2nd embodiment of the present invention, the 2nd carriage 123,136 and force transducer 124,137 are being set on two shaft ends 114,115 of touch roll 102 and the stepper motor 161 that constitutes tilting equipment are being set, member 162 when base end side is provided with the hinge folding in front.Stepper motor 161 is bearing on the shell 113 of elevator chamber 112 concurrently by supporting plate 163, with touch roll 102, and its output shaft 164 as Figure 10 institute pump ground be connected with the eccentric plectane 165 that moves up and down usefulness as eccentric shaft ground, between the 1st carriage 166 and force transducer 137 sliding part 169 is being set, it is to be made of the cylindric body 167 of above-below direction and the bar 168 that can be inserted into wherein with freely advancing and retreat.And on the body 167 of sliding part 169, be installed with along its radially outstanding shaft bearing plate 170, eccentric plectane 165 can be freely along circumferentially being entrenched in slidably in the bearing hole of shaft bearing plate 170.Promptly, make eccentric plectane 165 change the back, just sliding part body 167 moved to be equivalent to eccentric part, just to make front shaft end 114 liftings of the touch roll 102 that is installed on the dish with respect to axis hole 171 along ground, upward and downward side with respect to 171 of axis holes by the revolution of stepper motor 161.The lifting amount that adjustment amount and the cylinder 150 of usefulness forms owing to fascinate compares, is indivisible, thereby offset is just passable about with several mm.And for example shown in Figure 11, on supporting plate 163, form hold-down bolt 172 and insert general-duty slotted hole 173, stepper motor 161 makes along with eccentric plectane 165 drives.The permission along continuous straight runs departs from.On the other hand, leaf member 162 is by the 1st carriage 174 on the upper surface that is installed in shell 113; The axle 175 that direction from the 1st carriage 174 along cross-section touch roll 102 is supporting with extending; The lever on the top that one side can be bearing on the axle 175 pivotally, opposite side is installed in side force sensor 124 or plate 176 constitute.Promptly, constitute can be as the fascinate function of fulcrum of touch roll 102 for axle 175.Moving by these structure and cylinder 150 associations that fascinate, just can remain on touch roll 102 with respect to package 101 and control contact pressure on the relative position of regulation.Other structures are identical with above-mentioned the 1st embodiment with action effect.

Below, with reference to Figure 13 specific embodiments of the invention are described.This reeler is provided with two parallel bobbin holding elements 181,182; Make them suitably turn round the bobbin travel mechanism 180 of mobile usefulness.Respectively plug-in mounting a plurality of bobbins 183,184 on bobbin holding element 181,182, drive by the spindle motors revolution, thus, from spinning machine (not having expression the figure) hang down yarn y just batched on the bobbin 183 that in Figure 13, is positioned at the right side.The touch roll 102 that is provided with above-mentioned side force sensor and tilting equipment (not having expression among the figure) should batch side neck pipe 183 with this and contact pivotally and be provided with.And on elevator chamber 112, be provided with traverse range device 185 and yarn guide member 186.

Bobbin travel mechanism 180 hangs down mutually by two and closes coaxial like that approaching turntable dish 187; Turntable dish 187 is constituted around the rotating driver train of axle (not having expression among the figure) respectively.Turntable dish 187 is to constitute with onesize plectane, is bearing in respectively by the bearing outer circumference end on the bearer frame 189 of machine body 188.One side's turntable dish 187 is supporting bobbin holding element 181 and spindle motors in its outer circumferential surface section, and forms not must to give birth to the bobbin holding element 182 of the opposing party's turntable dish 187 and make it insert the opening that leads to with interfering.Promptly, a side bobbin holding element 181 can move in specialized range relative to the opposing party's bobbin holding element 182, for example can be at relative angle roughly from 90 ° to 270 °.Rotary motion mechanism for example is made into to move with motor by sprocket wheel and chain, with revolution makes turntable dish 187 change respectively.

Turntable dish 187 is suitably driven by controller shown in Figure 12 151, and the degreeof turn of the revolution (revolution of bobbin) of the touch roll of being determined by rotary sensor 145 102, the turntable dish 187 that detected by rotary encoder (not having expression among the figure) in addition is imported into controller 151 respectively.Then, calculate the coil diameter of package 101,181,182 revolutions of bobbin holding element are moved according to this value of calculating according to for example relation of bobbin revolution and coil diameter.In the present embodiment, be that the layer side face that makes bobbin holding element 181,182 be configured to batch the package 101 on the side neck pipe 183 is no more than the datum line L of continuity along the vertical direction and turns round non-contiguously with the opposing party's street pusher side bobbin 184 in machine body 188, just determine the angle of revolution θ of turntable dish 187 thus ₁, θ ₂

Below, the explanation present embodiment concrete effect.

As shown in figure 13, the position (P that full volume package 101 is doffed ₁) be taken at the amplitude direction center of machine body 188 and also be taken at the revolution mobile route circular orbit 190 bottom.And yarn y formally begins the position (P that batches ₂) begin and hour hands turn round on the position that about 55 degree ground and the position of doffing be separated by.Standby side neck pipe 184 is to be taken at from the position (P that doffs ₁) the beginning cw turns round the position (P that about 95 degree ground and the position of doffing are separated by ₃) go up by initial standby, like this,, be that cw is separated by with it with turning round about 150 degree from batching side neck pipe 183.And as shown in figure 13, each degreeof turn θ ₁, θ ₂All be from batching position (P ₂) angle set of beginning.

Revolution by spindle motors makes bobbin holding element 181 high speed rotaries that batch side, and yarn y is wound onto on the bobbin 183 of bobbin holding element through traverse range device 185 and touch roll 102.The revolution of spindle motors is controlled, peripheral speed (yarn speed) is become necessarily by controller 151.Here, the detected value of making by rotary sensor 145 as the revolution of bobbin output to controller 151, controller 151 is calculated the coil diameter of package 101 thus, according to this value of calculating actuating signal is input to rotary motion mechanism.Also be, rotating disk 187 be controlled to the degreeof turn θ of regulation with coil diameter ₁, θ ₂

Thus, along with coil diameter increases, batch side neck pipe 183 and move by the revolution of diagram cw gradually, the outer peripheral edges of layer are positioned at machine body 188 sides medially, promptly, make and batch side neck pipe 183 and move to the position (P that doffs with being no more than datum line L ₁).And in this coiling process, package 101 is moved on circular orbit 190, and touch roll 102 moves on vertical direction, makes the angle of contact (φ among the figure of package 101 and touch roll 102 thus ₁, φ ₂) change, though its result also changes contact pressure, force transducer can read this variation, carry out cooresponding therewith adjustment immediately.Promptly, can detect contact pressure linearly, and drive tilting equipment and lifting mechanism according to this detected value, thus contact pressure is controlled to that to begin to finishing from coiling all be the value of setting.

When batching side neck pipe 183 at the position (P that doffs ₁) when locating to become full volume, make spindle motors stop revolution, make elevator chamber 112 rise to upper limit position simultaneously.And make standby side neck pipe 184 turn round the position that moves to touch roll 102 with turning round about 75 degree separately along clockwise direction, carry out guide, simultaneously doffing with the bobbin 183 below the chassis that doffs (not having expression among the figure) enforcement.When the end of doffing, made elevator chamber 112 drop to lowering position, make the new side neck pipe that batches of formation turn round about 95 degree simultaneously, batching starting position (P ₂) formal the batching of beginning.Meanwhile or before and after this, make the bare bobbin revolution move to initial position of readiness (P ₃).

Like this, in the concrete action of present embodiment because on common circular orbit 190, the bobbin holding element 181 that makes a side batches starting position (P from the side ₂) gradually downwards and move inward; Make the opposing party bobbin holding element 182 standby side neck pipe 184 not with batch the mode shift position that side neck pipe 183 contacts with elevator chamber 112, thereby begin to the process of doffing from batching, the layer of package 101 can be outstanding from machine body 188 amplitude directions.Therefore, with former with the bobbin holding element keep each other 180 degree the reeler that moves of phase place ground compare, assembling joint square is dwindled, make the space minimizing is set.And in this reeler, change (φ because of angle of contact again by package 101 and touch roll 102 ₁→ φ ₂) and the available force transducer of variation of the contact pressure that produces directly detects, and be input to controller 151 with changing by the contact pressure that is bent to form of bobbin holding element 180, according to this detected value, tilting equipment and lifting mechanism can make touch roll 102 carry out minute movement, therefore, from batching the setting value that begins to finishing all contact pressure to be held in regulation, can improve the quality of package.

In the above-described embodiments, contact pressure testing agency is not limited to bend the force transducer 124,137 of instrument, can also use the load (and application force) of being measured touch roll 102 by other testing agencies such as piezoelectric types.In addition, in the above-described embodiments, tilting equipment is that the front at touch roll 102 is provided with and adjusts with cylinder 143 or stepper motor 161, but also can be arranged on the base end side, power elements such as cylinder can also be set on the both sides of touch roll 102 shaft end 114,115, constitute the roller position adjusting mechanism that is also used as tilting equipment and lifting mechanism thus.
