The specific embodiment
For the optimal way carrying out an invention
Below, explain with reference to accompanying drawing preferred embodiment of the present invention.In addition, in each figure, give identical symbol for identical or suitable part, the repetitive description thereof will be omitted.
Fig. 1 is the constructional drawing that has been suitable for the bar cutter that connects pressure roller of one embodiment of the present invention.As shown in Figure 1, bar cutter 10 possesses the portion of emitting 11, slitting portion 12 and reeling end 13.Emit portion 11 and emit thin slice S from the material roller R1 of rolling.Slitting portion 12 cuts into the thin slice S being emitted by the portion of emitting 11 width of regulation.Reeling end 13 batches the thin slice S of the width that is cut into regulation by slitting portion 12 as product roller R2.In bar cutter 10, thin slice S is carried along the transport path of regulation by multiple conveying rollers 14.In addition, thin slice S, for example, is plastic sheeting, laminated film, metallic paper, fabric etc.
On the transport path of the thin slice S between the portion of emitting 11 and slitting portion 12, configure as the roller in opposite directions 15 of guiding roller and connect pressure roller 1.Connect pressure roller 1 and be and the niproll that clamps thin slice S together with roller 15 in opposite directions.Roller 15 and connect the tension change that pressure roller 1 prevents the thin slice S in the portion of emitting 11 and propagate to slitting portion 12 in opposite directions thus.In addition, roller 15 in opposite directions, for example, is made up of the metal such as aluminum alloy, steel, the material that uses the carbon fibre fortified resin etc. of high resiliency carbon fibre to have the modulus of longitudinal elasticity below the above 400GPa of 60GPa.
On reeling end 13, be provided with touch roll 16.The thin slice S of touch roll 16 through batching be the pressure contact with regulation to the core C of product roller R2.Touch roll 16 prevents that air is involved in product roller R2 thus.In addition, core C, for example, be made up of the metal such as aluminum alloy, steel, the carbon fibre fortified resin that uses high resiliency carbon fibre, plastics, paper etc.
Then, to the structure that connects pressure roller 1 of roller 15 crimping in opposite directions being described through thin slice S.Fig. 2 is the cutaway view that connects pressure roller of one embodiment of the present invention.As shown in Figure 2, connect the outer tube 3 that pressure roller 1 possesses the axis 2 of drum and is configured in the drum in the outside of axis 2 to have the mode of identical with axis 2 centre line L.Axis 2 is the members that have as the outside 2a on the face of cylinder and the drum of inner face 2b.Axis 2, for example, be made up of the metals such as steel, the material that uses the carbon fibre fortified resin etc. of high resiliency carbon fibre to have the modulus of longitudinal elasticity below the above 470GPa of 190GPa.Outer tube 3 is the members that have as the outside 3a on the face of cylinder and the drum of inner face 3b.Outer tube 3, for example, be made up of the metals such as steel, the material that uses the carbon fibre fortified resin etc. of high resiliency carbon fibre to have the modulus of longitudinal elasticity below the above 470GPa of 100GPa.
Axis 2, by hole enlargement, chimeric with the inner face 3b of outer tube 3 at the central portion 2c of the direction parallel with centre line L.Under this state, outer tube 3 is fixed on the central portion 2c of axis 2 by bonding grade.More particularly, outer tube 3 has the member 3c, the 3c that are divided into two-part drum.At the central portion 2c of axis 2, be divided into two-part member 3c, 3c and engage with axis 2 under the state of docking mutually.
The outside of the part of the outside 2a(of axis 2 except central portion 2c) and the interval of the inner face 3b of outer tube 3, become below the external diameter × 0.10mm of outer tube 3.On the other hand, the interval of the outside 2a of axis 2 and the inner face 3b of outer tube 3, more than becoming the external diameter × 0.02mm of outer tube 3.Like this, by gap being set between the outside 2a at axis 2 and the inner face 3b of outer tube 3, can with outer tube 3, amount of deflection be separated by axis 2.
In addition, become the length (, in the situation that being called simply " length ", meaning the length of the direction parallel with centre line L below) of the central portion 2c at the junction surface of axis 2 and outer tube 3, can make outer tube 3 length 5～50%.Because the length at this junction surface is less, amount of deflection is more easily separated with outer tube 3 by axis 2, thus by roller in opposite directions 15 and the homogeneity that connects the clamping of the thin slice S that pressure roller 1 carries out improve.But, if the length at this junction surface, lower than 5%, exists because of undercapacity lifetime, or the danger of natural frequency decline.On the contrary, if the length at this junction surface exceedes 50%, because amount of deflection is difficult to be separated with outer tube 3 by axis 2, so exist by roller in opposite directions 15 and connect the deteriorated danger of homogeneity of the clamping to thin slice S that pressure roller 1 carries out.
And then, in each of the both ends of axis 2 2d, 2d, fix for rotating around centre line L and freely propped up the bearing 4 of accepting pressure roller 1.In addition, on the 3a of the outside of outer tube 3, formed the coating 5 for example being formed by metals such as Copper, nickel, chromium, iron, aluminium.Thus, can be suppressed on thin slice S in spite of wound.In addition, diagram is omitted, but has the situation that has covered rubber or rubber-like elastic body on the 3a of the outside of outer tube 3.
As described above, connecing in pressure roller 1, axis 2 is made up of the material with the modulus of longitudinal elasticity below the above 470GPa of 190GPa, and outer tube 3 is made up of the material with the modulus of longitudinal elasticity below the above 470GPa of 100GPa.Preferably, axis 2 is made up of the material with the modulus of longitudinal elasticity below the above 350GPa of 190GPa, and outer tube 3 is made up of the material with the modulus of longitudinal elasticity below the above 350GPa of 120GPa.The rigidity that thus, can suitably improve on one side axis 2 and outer tube 3 reduces the amount of flexibility (at the aviation value of the amount of flexibility of each position of the direction parallel with centre line L) of axis 2 and outer tube 3 on one side.And then the interval of the outside 2a of axis 2 and the inner face 3b of outer tube 3 becomes below the external diameter × 0.10mm of outer tube 3.Thus, can reduce the amount of flexibility of axis 2 and outer tube 3 and the amount of deflection of outer tube 3 poor (in the maxim of the amount of flexibility of each position of the direction parallel with centre line L and minimum value poor).At this, the amount of deflection of outer tube 3 is poor, by increase axis 2 and outer tube 3 at least one party external diameter or increase thickness, can reduce.As mentioned above, according to connecing pressure roller 1, the amount of flexibility reduction of axis 2 and outer tube 3 and the poor reduction of amount of deflection of outer tube 3.Thus, can be to have been carried out the load of 15 even action of roller in opposite directions of high rigidization in the mode being formed by the material with the modulus of longitudinal elasticity below the above 470GPa of 100GPa.In addition, if the interval of the inner face 3b of the outside 2a of axis 2 and outer tube 3 is made below the external diameter × 0.08mm of outer tube 3, can further reduce the amount of flexibility of axis 2 and outer tube 3 and the amount of deflection of outer tube 3 is poor.
In addition, connecing in pressure roller 1, more than the interval of the outside 2a of axis 2 and the inner face 3b of outer tube 3 becomes the external diameter × 0.02mm of outer tube 3.Thus, can prevent from resulting from axis 2 and outer tube 3 deflections and axis 2 contacts with outer tube 3.In addition, the manufacture that connects pressure roller 1 also becomes easy.
In addition, connect pressure roller 1, as using with the niproll that clamps thin slice S together with roller in opposite directions 15 as guiding roller.In the case, in bar cutter 10, can and connect pressure roller 1 by roller in opposite directions 15 and clamp equably thin slice S.Thus, can prevent that thin slice S produces breakage on thin slice S at Width crankle or in slitting portion 12 in slitting portion 12.
At this, connect pressure roller 1 for what use as niproll, require the first～four following point.
First be connect pressure roller 1 spread all over the Width of thin slice S whole scopes to be close to thin slice S on roller 15 in opposite directions upper and thin slice S is produced to uniform Clamping force (in opposite directions roller 15 and connect pressure roller 1 and clamp the power of thin slice S).Its reason be because, if any one position that connects pressure roller 1 in the direction parallel with centre line L does not produce uniform Clamping force, exist be involved in product roller R2 on the amount of air between thin slice S, produce spot and be related to various danger of batching shortcoming.
Second point is that to connect the amount of deflection of pressure roller 1 little.Its reason be because, connecing pressure roller 1 through thin slice S during to roller 15 crimping in opposite directions, if connect pressure roller 1 deflection, roller 15 is in opposite directions acted on to the load less than desirable load, existence can not obtain the danger of the performance that connects pressure roller 1.
Thirdly that to connect the high speed performance of pressure roller 1 good., be thirdly natural frequency (permissible speed) height that connects pressure roller 1.Its reason is because if it is low to connect the natural frequency of pressure roller 1, exists and connect the danger of pressure roller 1 from vibration in rotation.
The 4th is the low cost of manufacture that connects pressure roller 1.Its reason is because kind, the quantity of the niproll that generally should prepare are more than other roller.
According to the above-mentioned pressure roller 1 that connects, because the amount of flexibility of axis 2 and outer tube 3 is lowered and poor being lowered of amount of deflection of outer tube 3, so first and second point are satisfied.
In addition, because axis 2 and outer tube 3 have been carried out high rigidization, so natural frequency is enhanced, its result, is thirdly also satisfied.Particularly, in the situation that axis 2 and outer tube 3 are made up of carbon fibre fortified resin, because axis 2 and outer tube 3 are carried out lightweight, so can further improve natural frequency.But if at least one party of axis 2 and outer tube 3 is made up of carbon fibre fortified resin, it is poor can suitably to reduce the amount of flexibility of axis 2 and outer tube 3 and can suitably reduce the amount of deflection of outer tube 3.
And then, because the structure that connects pressure roller 1 is simplified, thus the 4th be also satisfied.Particularly, in the situation that axis 2 and outer tube 3 are made up of steel, due to the cost step-down of the material of axis 2 and outer tube 3, so can realize the cost degradation that connects pressure roller 1 self.But if at least one party of axis 2 and outer tube 3 is made up of steel, it is poor can suitably to reduce the amount of flexibility of axis 2 and outer tube 3 and can suitably reduce the amount of deflection of outer tube 3.
Then, the above-mentioned manufacture method that connects pressure roller 1 is described.First, prepare to be divided into two-part outer tube 3(, member 3c, 3c).Next, each insertion of both ends 2d, the 2d of axis 2 has been divided in each of two-part outer tube 3, makes to be divided into two-part outer tube 3 at the central portion 2c of axis 2 and dock.Then,, under this state, by by bonding grade, outer tube 3 being fixed on to the central portion 2c of axis 2, at the central portion 2c of axis 2, will be divided into two-part outer tube 3 and engage with axis 2.
Connect the manufacture method of pressure roller 1 according to this, even by the interval of the inner face 3b of the outside 2a of axis 2 and outer tube 3 in the case of having reduced in the scope below the external diameter × 0.10mm of outer tube 3, also can be easily and precision manufacture well possess the axis 2 that interfixes at central portion 2c and outer tube 3 connect pressure roller 1.More particularly, because the centering of axis 2 and outer tube 3 is easy, so can manufacture the eccentric little pressure roller 1 that connects.In addition, because the amount of deflection of arbor (axis 2) is little, connect pressure roller 1 so can accuracy of manufacture good.
