And and the throughput direction (Fig. 5 left and right directions) of sheet material S slightly at right angles, the cause of transverse shift does not take place in feeding sheets S stably, causes the transporting velocity high speed of sheet material S, can seek to shorten the manufacturing time of volume towel M.

The two ends of head roll 23 and auxiliary cylinder 24 are supplied with platform 21 and are fixed by pedestal as shown in Figure 5, and wherein a side (Fig. 5 downside) has disposed connection gear 23a respectively and has been connected gear 24a.At this, the connection status of relevant supply motor 81a is described with reference to Fig. 6 (a).

Fig. 6 (a) supplies with part 20, with connecting the side view that gear 23a and the configuration plane that is connected gear 24a etc. are seen.Omitted a part of supplying with platform 21 grades among Fig. 6 (a).

The horizontal gear that head roll 23 and auxiliary cylinder 24 have disposed respectively by plastics forming connects gear 23a and is connected gear 24a.Connect gear 23a and is connected gear 24a shown in Fig. 6 (a), and is connected gear 26 and coincide, this connection gear 26a is identical by some connection gears that are not illustrated and cam (nothing illustrates) that supply motor 81a rotating shaft is set.

Therefore, when supply motor 81a rotates, its power is by cam, no illustrated connection gear, connection gear 26 and connect gear 23a, connect gear 24a is delivered to head roll 23 and auxiliary cylinder 24, makes (Fig. 6 (a) right) rotation in the direction of the clock of head roll 23 and auxiliary cylinder 24.Finally cause supplying with sheet material S on the platform 21 under the rotary power effect of head roll 23 and auxiliary cylinder 24, advance by horizontal direction (Fig. 6 (a) right).When extracting sheet material S out, this sheet material S is transported to severing part 30 described later and water spray part 42 (with reference to Fig. 4) by towel reel R.

Returning Fig. 5 describes, the side (Fig. 5 upside) of supply platform 21 as shown in Figure 5, disposed rotary inductive sensor 27, this rotary inductive sensor 27 is the revolution inductors that are used to detect head roll 23, comprised the rotating part 27a that is contained on 23 of the head rolls, and the detecting element 27b that detects rotating part 27a action.With reference to Fig. 6 (b), the relevant method of utilizing rotary inductive sensor 27 to detect head roll 23 revolutions is described at this.

Fig. 6 (b) supplies with part 20, the side view of being seen by the configuration plane of rotary inductive sensor 27.Omit a part of supplying with platform 21 grades among Fig. 6 (b).

Be configured in rotating part 27a on 23 of the head rolls shown in Fig. 6 (b), disposed to the outstanding protuberance 27a1 of radial direction.Be accompanied by the protuberance 27a1 of the rotation of head roll 23, be detected the 27b of portion and detect by photoelectricity sub-prime and photodiode, convert pulse to after, calculate the revolution of head roll 23.

Head roll 23 approximately is 30mm at the outer perimeter in should use-case.When supposing to extract the sheet material S of 150mm out from towel reel R, after supply motor 81a (with reference to Fig. 6 (a)) starts, rotary inductive sensor 27 detects the revolution of head rolls 23, the 5th change detecting (30mm * 5 change=stop the rotation of supply motor 81a 150mm) time.So just can supply the sheet material S of 150mm.

Original volume tissue manufacturing method is an extraction length of releasing a yard device (for example being the anglec of rotation that detects per 15 degree) detection sheet material S by rotary, and its induction speed is restricted, when head roll rotates at a high speed, can not carry out high accuracy and detect.In should be with row, calculate the extraction length of sheet material S by the revolution that detects head roll 23, can improve induction speed, even head roll 23 at a high speed rotation the time, also can correctly detect the extraction length of sheet material S.Therefore rotating speed that can high speed head roll 23, thereby the transporting velocity of high speed sheet material S can seek to shorten the manufacturing time of volume towel M.

In addition, rotary inductive sensor 27 becomes the discoid while to cut out breach on this disk at rotating part 27a, makes detecting element 27b detect the revolution of this breach.But, on such structure, might stick on this breach because of the bits that cut of sheet material S, hide this breach and cause detecting element 27b correctly not detect.In addition, rotary inductive sensor 27 as should use-case, the protuberance 27a1 outstanding by radial direction is set on the rotating part 27a, and protuberance 27a1 passes through to be detected the structure that the 27b of portion is detected, the adhesion of cropped bits does not influence, and correctly detects the revolution of head roll 23.

Returning Fig. 4 describes.As mentioned above, inboard at loam cake 3, the cylinder 25 of exerting pressure that can rotate freely is fixed (with reference to Fig. 1) in the inboard of loam cake 3 by support 3a, when closing loam cake 3, on the structure this exert pressure cylinder 25 down direction (Fig. 4 below) exert pressure for the head roll 23 of supplying with part 20.Can make the sheet material S that supplies with on the platform 21 be pressed on the head roll 23 like this, prevent the idle running of head roll 23, towel reel R positively extracts sheet material S out.At this, the detailed structure of the relevant cylinder 25 of exerting pressure is described with reference to Fig. 7.

Fig. 7 is the side view of cylinder 25 and head roll 23 of exerting pressure, and illustrates the state that the cylinder 25 of exerting pressure is pressed in sheet material S head roll 23.Fig. 7 has omitted the part of support 3a etc.Above the support 3a along the vertical direction (Fig. 7 above-below direction) inlayed vertical slot 3a1, the cylinder 25a that exerts pressure of the head roll 23 among this vertical slot 3a1 can rotate, simultaneously can about (Fig. 7 above-below direction) move.

In addition, as shown in Figure 7, by built-in, therefore, the elastic recoil power order cylinder 25 of exerting pressure has the stress of (direction under Fig. 7) downwards with the state of compression for built-in compression spring 7, this compression spring 7 among this vertical slot 3a1.(Fig. 7 above-below direction) moves about the thickness t of cylinder 25 corresponding sheet material S of exerting pressure, and the pressure by compression spring 7 is produced makes sheet material S can be close to head roll 23.When loam cake 3 is closed, when the fixing feet 3b of this loam cake 3 is fixed on the retainer 6 of main frame 2 (with reference to Fig. 1 and Fig. 4), ignore the thickness t of sheet material S, can stably sheet material S be extracted out from towel reel R.

And, the cause that the cylinder 25 of exerting pressure that the error of the thickness t of sheet material S can be moved up and down is offset, even use thicker sheet material S, the thickness difference of this sheet material S can not make loam cake 3 float at the top of main frame 2 yet.Therefore, can between loam cake 3 and main frame 2, not produce the slit, can closely close loam cake 3, not destroy overall appearance U.S. of volume tissue manufacturing method 1.And loam cake 3 closely is combined in the cause at the top of main frame 2, even inadvertently placed weight on loam cake 3, can prevent that also this from repeating to make exert pressure head roll 23 pressure of 25 couples of sheet material S of cylinder to exert an influence.

The periphery of head roll 23 as shown in Figure 7, covered can strain cushion 28.As the thick material of this cushion 28, can be synthetic rubber, rubber or sponge etc.In addition, auxiliary cylinder 24 is coated with cushion 28 similarly.

Exert pressure cylinder 25 periphery as mentioned above, disposed many (should use-case be 4) elastic tapes 29 (with reference to Fig. 1).Therefore, when the cylinder 25 of exerting pressure is pressed sheet material S toward head roll 23, the ledge that is configured in the elastic tape 29 of cylinder 25 peripheries of exerting pressure can be coated over the distortion that the cushion 28 of head roll 23 peripheries produces and bear, as shown in Figure 7, sheet material S can be absorbed in the cushion 28 simultaneously with elastic tape 29.

Therefore, sheet material S can be crushed on the head roll 23 more powerfully, prevents skidding between head roll 23 and the sheet material S, positively feeding sheets S.Cause driving (rotation) speed of head roll 23 can high speed, improve the transporting velocity of sheet material S, can seek to shorten the manufacturing time of volume towel M.

In addition, during the sheet material S incoming terminal of towel reel R,, also can prevent skidding with respect to the head roll 23 of sheet material S even when the extraction resistance of sheet material S increases, strengthen the rotational resistance of head roll 23, positively make supply motor 81a (with reference to Fig. 6 (a)) produce super-high-current.Finally, super-high-current is detected by excess load detecting circuit 81b, to CPU71 (jumper terminal 71a) output (with reference to Fig. 3) detecting signal 93, can detect the sheet material S incoming terminal of towel reel R really.

The screen resilience of compression spring 7 wishes to be controlled at about 50g～250g, should be set to about 150g in the use-case.In the time of screen resilience deficiency 50g, sheet material S can not be pressed on the head roll 23, might cause skidding between head roll 23 and the sheet material S; If when exceeding about 250g, the rotational resistance of head roll 23 increases, and makes supply motor 81a that load is superfluous, might cause the mistake that detects of super-high-current.

Returning Fig. 4 describes.Auxiliary cylinder 24 is located at head roll 23 rear sides as shown in Figure 4.Supply with near the inlet of platform 21 and protecting cover 22 formed transport paths.This transport path is the cause with the warp architecture of sheet material S guiding below (Fig. 4 below) as mentioned above, and the transporting velocity of sheet material S is by high speed the time, because transporting resistance results in blockage etc., is difficult to stablize feeding sheets S.

At this, volume tissue manufacturing method 1 relative this problem that should use-case has disposed auxiliary cylinder 24 near the inlet of transport path.So, the sheet material S by towel reel R extracts out can be extruded into transport path owing to the rotary power of auxiliary cylinder 24, makes sheet material S not stop up the bending delivery path, is transferred glibly.Finally make the transporting velocity high speed of sheet material S, can seek to roll up the manufacturing time of towel M.

At this, the upside of transport path, promptly protecting cover 22 extends to the top (Fig. 4 top) of auxiliary cylinder 24 as shown in Figure 4.When even the obstruction of transport path or frictional resistance make sheet material S by warpage, moving that this sheet material S makes progress also can be limited by protecting cover 22.The rotary power of auxiliary cylinder 24 can efficient be delivered to sheet material S well, positively sheet material S is squeezed into transport path, finally feeding sheets S stably.

In should using, illustrated owing to be built in the screen resilience of the vertical slot 3a1 of support 3a, exert pressure cylinder 25 with head roll 23 (sheet material S) toward below in (below Fig. 4).But just be not limited to this method, for example vertical slot 3a1 directly exerts pressure, perhaps omit vertical slot 3a1, adopt the helical spring elastomeric material to make loam cake 3 self possess elastic force to supplying with part 20 (head roll 23) direction, the cylinder 25 that causes exerting pressure also is feasible to the structure that head roll 23 (sheet material S) is exerted pressure downwards.Also have to rely on the weight of loam cake 3 self, the cylinder 25 that causes exerting pressure also is feasible to the structure that head roll 23 (sheet material S) is exerted pressure downwards.

The front side of head roll 23 (Fig. 4 left side) as shown in Figure 4, has disposed light sensor 120.This light sensor 120 is the sensors that have or not sheet material S on the transport path of detect supplying with on the platform 21, on the structure is to detect having or not of sheet material S according to the variation of the volume reflection of irradiation light.When the super-high-current method of above-mentioned employing supply motor detecting circuit 81b detection supply motor 81a can not detect the terminal of sheet material S, also can utilize light sensor 120 to detect sheet material S incoming terminal.

For example, the sheet material S that ignores towel reel R is incoming terminal, the coupling part of the terminal of sheet material S and axle core is because of making bad or when extracting load out and peel off, the cause that the extraction resistance of sheet material S can not increase, cause the load of supply motor 81a can not increase, above-mentioned excess load detecting circuit 81b can not detect super-high-current.Finally, can not detect sheet material S incoming terminal.

As shown in Figure 4, (should use-case be the side of head roll 23) configuration light sensor 120 on the transport path of sheet material S detects and has or not sheet material S., when be stripped from the coupling part of the terminal of sheet material S and axle core, the terminal of this sheet material S was transported to the rear side of transport path, does not have sheet material S on the transport path.Therefore, can detect the existence that has or not sheet material S on the transport path, really at the sheet material S that detects towel reel R incoming terminal whether by light sensor 120.

In addition, wish that light sensor 120 is to be configured on severing part 30 transport path before.On the transport path of severing part 30 fronts, sheet material S incoming terminal and and the scope do not peeled off of coupling part of axle core in, sheet material S exists always; And on the transport path of severing part 30 back, as described later, the manufacturing engineering of corresponding volume towel M, having or not of sheet material S changes.Therefore, when light sensor 120 is configured in severing part 30 back,, having or not of detection lug material S just not, also need to detect the progress situation of the manufacturing engineering of volume towel M in order to detect whether incoming terminal of sheet material S.This will cause this control operation complicated, increase equipment cost.

In addition, light sensor 120 more wishes to be configured on auxiliary cylinder 24 transport path before.The terminal of sheet material S is by behind the auxiliary cylinder 24, cannot be again to the driving force of sheet material S interpolation towards throughput direction, shape, length or surface state etc. according to transport path, sheet material S might be left on the transport path of auxiliary cylinder 24 back, causes the terminal part of this residual sheet material S to be detected by light sensor 120.

In addition, as volume tissue manufacturing method 1 that should use-case, the allocation position of light sensor 120 is when head roll 23 fronts, the head roll 23 and the above-mentioned cylinder 25 of exerting pressure are synchronous, during the terminal of sheet material S is passed through light sensor 120, can add driving force for constantly sheet material S, carry really.The terminal part that prevents sheet material S is by light sensor 120 error inspections.

Light sensor 120 is the surface of emission (luminescence unit 120a) and the receiving planes (light receiving unit 120b) that expose light towards sheet material S (Fig. 4 upside, Fig. 5 drawing front side), is embedded in to supply with on the platform 21 (with reference to Fig. 5).With reference to Fig. 8, the detailed structure of relevant light sensor 120 is described at this.

Fig. 8 (a) is the front elevation of light sensor 120, and Fig. 8 (b), (c) are the principle schematic that light sensor 120 detects sheet material S, when (b) illustrating sheet material S and exist on transport path; (c) illustrate sheet material S on transport path, do not deposit big in.In addition, Fig. 8 (b), (c) are the side views of supplying with part 20, corresponding diagram 4 loam cakes 3 closed conditions.

Light sensor 120 has comprised the luminescence unit 120a that launches ultrared light source, and the light receiving unit 120b that receives this reflection ray.The light emission face of luminescence unit 120a and the light receiving surface of light receiving unit 120b are configured on the light sensor 120 same planes shown in Fig. 8 (a).In addition, should the light sensor 120 of use-case in, luminescence unit 120a is an infrared LEDs, light receiving unit 120b is made of phototransistor, still, emission light is not limited to infrared ray, the emission of the light of other wavelength (reception) also is feasible.

By luminescence unit 120a emission light, shown in Fig. 8 (b), (c), when the infrared ray of being penetrated by object (sheet material S or loam cake 3) was received by light receiving unit 120b, this light income was converted to digital value by sensor control circuit 89 (with reference to Fig. 3) A D and is then read by CPU71 (with reference to Fig. 3).Whether CPU71 exceeds predetermined value according to read value, judges having or not of sheet material S.

In detail, when sheet material S exists on transport path, shown in Fig. 8 (b), the cause that the infrared ray of being launched by luminescence unit 120a is directly reflected by sheet material S, the light income of light receiving unit 120b is big (more than the colour gamut value of regulation); Sheet material S does not exist on transport path, and shown in Fig. 8 (c), the infrared ray of being launched by luminescence unit 120a is by the cause of the inner reflection of the farther loam cake 3 in this sheet material S position, the light income of light receiving unit 120b more less (the colour gamut value of regulation is following).Finally, the light income of corresponding light receiving unit 120b can detect having or not of sheet material S.

So, volume tissue manufacturing method 1 that should use-case can detect having or not of sheet material S by light sensor 120 contactless state, even be full of the sheet material S of flexibility, also can positively detect having or not of this sheet material S.

In addition, when sheet material S was light color (for example white etc.), the inboard of loam cake 3 wished it is dark (for example black etc.) structure; When sheet material S was dark, the inboard of loam cake 3 wished it is light structure; So, the amount that increases the reflection ray that having or not of corresponding sheet material S change is poor, can positively improve the accuracy that detects of light sensor 120.

Return Fig. 4 and describe, severing part 30 is with (Fig. 4 below) sheet material S of supply presses the device of designated length severing toward the below by above-mentioned supply part 20, has mainly disposed dead knife 31 and cylinder knife 32.Dead knife 31 is configured in the banner direction (vertical direction of Fig. 4 paper) of sheet material S; On the relative position that clips sheet material S with dead knife 31, disposed rotatable cylinder knife 32.Cylinder knife 32 is connected with severing motor 82a (with reference to Fig. 3) by connecting gear (not having diagram), this severing motor 82a drive circuit is by the frequency rotation of appointment, cylinder knife 32 begins on the position of designated length severing with the sheet material S that clips between the dead knife 31 by first end parts with (Fig. 4 circles round on a left side) direction rotation counterclockwise.

Water supply part 40 is the parts to sheet material S supply moisture, has mainly disposed water box slot 41, jet pump 83a, heater 84a and water spray part 42.Water box slot 41 is parts of depositing the water tank T that can freely load and unload, is configured in than supplying with the dorsal part (Fig. 4 right side) of part 20 near main frame 2.Water tank T is built in the water box slot 41 with handstand state, and this feed water inlet Tm is connected with jet pump 83a by water pump suction pipe.

Water tank T is configured in than supplying with part 20 and water spray part described later 42 dorsal part (Fig. 4 right side) near main frame 2, as shown in Figure 4, when supply part 20 is pumped sheet material S, also can carry out the replacing of water tank T by towel reel R.Therefore, can when just changing water tank T, when water tank T is taken out, not need to carry out the complex work of backrush in main frame 2 without exchanging water tank T and towel reel R the same period by the sheet material S that supplies with part 20 extractions.

The discharge outlet of jet pump 83a is to connect heater 84a and water spray part 42 by water-supply-pipe 43.The inner water that can preserve specified amount on the heater 84a structure when opening heater button (not having diagram), can be controlled inner heating of preserving water, maintains the temperature of appointment.In addition, should use-case in, jet pump 83a is configured in the top of heater 84a, jet pump 83a also can be configured in the below of heater 84a certainly.

Water spray part 42 is the parts that the water by jet pump 83a supply are sprayed onto the sheet material S that is supplied by supply part 20, has mainly disposed water spray plate 42a, baffle plate 42b and nozzle 42c.Omitted the part of the water-supply-pipe 43 that is connected with heater 84a, water spray part 42 among Fig. 4.

On water spray plate 42a, baffle plate 42b is laid by the slit of appointed interval, and this space is the transport path of sheet material S.On the water spray plate 42a, the banner direction of sheet material S (Fig. 4 paper vertical direction) has interted the nozzle 42c of a plurality of sensing baffle plate 42b by appointed interval.Therefore, when jet pump 83a is driven by specified frequency, to sheet material S water spray, can add moisture all for fifty-fifty sheet material S by transport path by nozzle 42c.

The upper end of water spray plate 42a and the formed transport path of baffle plate 42b is the outlet back that is connected the transport path of supplying with part 20, can positively accept on the structure by supplying with the sheet material S that part 20 hangs down.In addition, its lower end is configured on the conveyer belt 51 of shaped portion 50 described later, and the part of water spray drips on the sheet material S that transports to shaped portion 50, and formation can water-saving structure.

By the sheet material S of severing part 30, be transported on shaped portion 50 about conveyer belts 51 when supplying with moisture, be sent to the rear side (Fig. 4 left side) of shaped portion 50 by the designated length severing by water spray part 42.

Shaped portion 50 is the devices that sheet material S formed columned volume towel M, mainly is made of conveyer belt 51, cover 52, reverse conveyer belt 53.

Should just roll up towel M on volume tissue manufacturing method 1 structure of use-case in one-sided (Fig. 4 upside) formation of conveyer belt 51.Therefore, as mentioned above, even towel reel R is configured in the front side of main frame 2, when sheet material S is pulled to the dorsal part of main frame 2 (with reference to Fig. 4), causing the processing of this sheet material S to handle the path can be not complicated, discharge volume towel M in the front side of the main frame 2 that has disposed guidance panel 4, the miniaturization that finally can seek to roll up tissue manufacturing method 1 provides good volume tissue manufacturing method 1 easy to use to the user.At this, the detailed structure of shaped portion 50 is described with reference to Fig. 9.

Fig. 9 (a) is the vertical view of shaped portion 50, and Fig. 9 (b) is the sectional view of the shaped portion 50 on the VIIIb-VIIIb dotted line of Fig. 9 (a).When Fig. 9 (a) and (b) illustrate the part section of conveyer belt 51 or shell 54, omitted the jut 51b that the whole projection of the appearance of conveyer belt 51 is provided with among the figure.

Conveyer belt 51 is that Zhou Quanti has the Rubber Conveyor Belt Scrap of a plurality of jut 51b outside shown in Fig. 9 (a), is erected between the rotatable a pair of swing roller 51a that is supported by shell 54.The opposite of the transporting flat of these conveyer belt 51 tops (Fig. 9 (a) paper front, Fig. 9 (b) top) has disposed cover 52.

The front portion of cover 52 is that the center can be fixed with rotating freely with axle 52c for convenient importing sheet material S becomes circular-arcly.In addition, roughly disposed spring retainer 52d in the centre of cover 52; Dispose the spring retainer 54b of the other end on the shell 54, hung coil spring 52e between spring retainer 52d and the spring retainer 54b.Shell 54 is provided with the groove 54c of coil spring 52e.

On cover 52, and there is a plurality of projection 52a to form the tabular projection of laundry between the opposite face of conveyer belt 51.Therefore, can rely on conveyer belt 51 to add suitable friction (with reference to Figure 13 (a)) for the sheet material S that is transferred, positively when the tip of sheet material S forms volume towel nuclear, this volume towel nuclear is being pressed under the state of conveyer belt 51 with suitable pressure by cover 52, follows moving of conveyer belt 51 and becomes big.Finally, can seek with this volume towel nuclear is the center, can positively sheet material S be rolled into tubular, and it is bad to suppress to be shaped.

Shown in Fig. 9 (b), rake 52b is set to be inclined upwardly towards the throughput direction of sheet material S (Fig. 9 (a) and (b) left) at the rear portion of cover 52 (Fig. 9 (a) and (b) left side).This rake 52b is the part (with reference to Figure 13 (b)) that tubular is kept sheet material S when being shaped, shown in Fig. 9 (a), on the banner direction of conveyer belt 51 by appointed interval such as comb shape disposed many (should use-case be 6).On the downside of each cover 52 (Fig. 9 (a) paper back side),, be provided with the tabular projection of laundry in addition as cover 52.

Between each of these conveyer belts 51 is adjacent, many (should use-case be 5) reverse conveyer belts 53 have been disposed.Reverse conveyer belt 53 is the slightly circular rubber school system belts in cross section, when being erected between a pair of swing roller 53a that rotates freely that is supported by shell 54, pull together sheet material S is rolled into tubular (with reference to Figure 13 (b)) with conveyer belt 51, shown in Fig. 9 (b), be configured in the opposite of conveyer belt 51.

At this, the two ends that are transferred the swing roller 53a on the direction (Fig. 9 (a) and (b) left side) of sheet material S within a pair of swing roller 53a, be embedded in the vertical slot 54a of the above-below direction on the shell 54, can move to the opposite direction (Fig. 9 (b) top) of conveyer belt 51 directions (Fig. 9 (b) below) or conveyer belt 51 when can freely rotate.Therefore, when sheet material S is rolled into tubular, be accompanied by the increase of drum diameter, can make reverse conveyer belt 53 be moved upward (with reference to Figure 13 (b)), can ignore thickness or the length of sheet material S, swimmingly processing volume towel M.

In addition, on the terminal side of conveyer belt 51 opposite directions (Fig. 9 (b) top) of vertical slot 54a, disposed outstanding retainer 54a1, when can follow the increase of drum diameter of sheet material S at the swing roller 53a that vertical slot 54a is fixed (Fig. 9 (b) top) rises upward, adopt retainer 54a1 to stop swing roller 53a, prevent that it from being come off by vertical slot 54a.

And, with respect to this retainer 54a1 shown in Fig. 9 (b), the throughput direction (Fig. 9 (a) and (b) left) of pressing sheet material S forms projection, the swing roller 53a that vertical slot 54a is fixed, owing to the screen resilience of reverse conveyer belt 53 has stress towards swing roller 53a, more can bring into play the effect that adopts retainer 54a1 to stop swing roller 53a, can prevent positively that swing roller 53a from being come off by vertical slot 54a.

Set up the swing roller 51a of conveyer belt 51 an end (Fig. 9 (a) upside) the axle on disposed belt pulley 51a1; This belt pulley 51a1 connects the belt pulley 56a that carries motor unit 56 by conveyer belt 55.In addition, carrying built-in conveying motor 85a (with reference to Fig. 3) in the motor unit 56, is that the rotary power of this conveyings motor 85a is exported to belt pulley 56a by reduction gearing (do not have and illustrate) on the structure.Therefore, when carrying motor 85a rotation, this rotary power is communicated to the belt pulley 51a1 of swing roller 51a by reduction gearing, belt pulley 56a and conveyer belt 55, causes conveyer belt 51 with (Fig. 9 (b) anticlockwise) rotation counterclockwise.

In addition, set up on the axle of an end (Fig. 9 (a) upside) of the swing roller 53a of reverse conveyer belt 53 and disposed belt pulley 53a1, this belt pulley 53a1 connects the belt pulley 58a that carries motor units 58 by conveyer belt 57.In addition, carrying built-in reverse motor 86a (with reference to Fig. 3) in the motor unit 58, is that the rotary power of this reverse motor 86a is exported to belt pulley 58a by reduction gearing (not having diagram) on the structure.Therefore, when reverse motor 86a rotates, this rotary power is communicated to the belt pulley 53a1 of swing roller 53a by, belt pulley 58a and conveyer belt 57, causes reverse conveyer belt 53 (Fig. 9 (b) right rotation) in a clockwise direction, promptly with 51 one-tenth opposite spins of conveyer belt.

In addition, the output characteristics of considering to carry motor unit 56 and carrying motor unit 58, the diameter of the diameter of each belt pulley 56a, belt pulley 58a etc. and each swing roller 51a, swing roller 53a or driving resistance etc., the obverse absolute velocity of setting conveyer belt 51 and reverse conveyer belt 53 about equally.

Hang down into the sheet material S of the front portion (Fig. 9 (a) and (b) right side) of the throughput direction of conveyer belt 51 by above-mentioned water spray part 42 (with reference to Fig. 4), (Fig. 9 (a) and (b) left to) is transferred (with reference to Figure 13 (a)) towards the rear portion by the rotation of conveyer belt 51.Cause sheet material S and the corresponding surface of cover 52 between, when tip forms volume towel nuclear, and the corresponding surface of reverse conveyer belt 53 between, the downside that is tilted the 52b of portion is kept, with this volume towel nuclear is that the center is rolled into tubular (with reference to Figure 13 (b)), forms columned volume towel M.

And the corresponding surface of reverse conveyer belt 53 and conveyer belt 51 as mentioned above, mutually moves with about equally speed in reverse direction.Therefore, sheet material S can be tilted the downside of the 52b of portion and keep and be rolled into tubular, shortens the processing path (conveyer belt 51 and reverse conveyer belt 53) at this place, seeks the miniaturization of shaped portion 50.In addition, obverse relative speed difference becomes big cause, can make the forming speed high speed of sheet material S, seeks to shorten the curring time of volume towel M.

Return Fig. 4 and describe, the volume towel M by shaped portion 50 formed therebies by the rotation of conveyer belt 51, is sent to inclined guide plate 61, as shown in Figure 4, continues guiding by inclined guide plate 61, is discharged on the dual-purpose pallet cover 5.

Below, arrive the flowchart text of Figure 12 such as the volume tissue manufacturing method 1 practiced processing of above-mentioned structure with reference to Figure 10.

Figure 10 is the sheet material S incoming terminal of expression towel reel R, when supply motor 81a flows through super-high-current, detects the flow chart of processing (wire jumper processing) by the practiced excess load of CPU71.This excess load detects to be handled when stopping to drive supply motor 81a, to the sheet material S incoming terminal information of user notification towel reel R.

The sheet material S incoming terminal of towel reel R, when supply motor 81a flow through super-high-current, the detecting signal 93 of excess load detecting circuit 81b was output to the jumper terminal 71a of CPU71.(with reference to Fig. 3) at this moment, the control that the CPU71 interruption of work is carried out, the excess load of carrying out Figure 10 detects processing.

Excess load detects in the processing, has at first carried out to stop to handle (S21).Stopping to handle (S21) is the processing that stops to roll up the manufacturing of towel M by volume tissue manufacturing method 1, and CPU71 drives loop 81～83,85 and 86 output stop signals to each, stops the driving (with reference to Fig. 3) of each

motor

81a, 82a, 85a, 86a and 83a.

So, in the time of the sheet material S incoming terminal of towel reel R, can prevent that supply motor 81a from continuing unnecessary action, prevent from rotating shaft or connect

gear

23a, 26 etc. to bear excessive revolving force and cause rotating shaft or connect gear 23a, breakages such as 26.And noise that the unusual driving condition that can prevent supply motor 81a produces down or the fault of supply motor 81a self.

In addition, carry motor 85a in the processing of S8 described later driven the time, identical when this driving is stopped with supply motor 81a, can prevent (with reference to Figure 11) such as breakage, noise or faults.Simultaneously, when jet pump 83a is driven, when being stopped, this driving can suppress the waste of water.

After implementation stops to handle (S21), then carry out and report processing (S22).This reports processing (S22) is with the processing to user notification of the information of the sheet material S incoming terminal of towel reel R.CPU71 is to sound and warning light control circuit 87 output caution signals, in the time of with the LCD4b warning, by loudspeaker 88 sound that gives a warning.Therefore, can allow the user realize sheet material S incoming terminal immediately.

After processing (S22) was reported in implementation, the user opened before loam cake 3 (with reference to Fig. 4) the exchange towel reel R, and cycling should be handled.In addition, when loam cake 3 is unlocked, as mentioned above, the contact of limit switch SW1 is disconnected, the cut cause of power supply, the user is extracted out by volume tissue manufacturing method 1 and is supplied to the sheet material S that part 20 is transported to volume tissue manufacturing method 1 inside, the towel reel R that can more renew glibly.

Figure 11 is the flow chart by the practiced main processing of CPU71.This processing is begun when connecting the power supply of volume tissue manufacturing method 1, during connecting power supply, and the processing that repeats to implement by CPU71.In addition, this is mainly handled in the enforcement, and when the detecting signal 93 that supply motor detecting circuit 81b sends was imported into CPU71, as mentioned above, the excess load of Figure 10 detected processing (wire jumper processing) and is implemented immediately.

At this, the explanation of the main flow chart of handling can be suitably with reference to Figure 13.Figure 13 is at shaped portion 50 schematic diagram that the tubular of sheet material S be shaped to handle of separating by time.Figure 13 (a) is the schematic diagram of the indrawn state of sheet material S in the shaped portion 50; Figure 13 (b) is the schematic diagram that is rolled into the state of tubular at the sheet material S of shaped portion 50; Figure 13 (c) is the schematic diagram of being discharged the state of volume towel M by shaped portion 50.The sectional view of the shaped portion 50 on the VIIIb-VIIIb dotted line of Figure 13 (a)～(c) difference corresponding diagram 9 (a).

CPU71 is relevant to main processing, at first carries out initial setting and handles (S1).This is handled as mentioned above, is the state with each drive unit of having or not that detects towel reel R (sheet material S); When result etc. is represented by LCD4b, sheet material S is set in the processing of primary position (initial stage length), or correspondence presses when starting button 4c, sets interruption routine and is activated processing etc., sets the state that volume tissue manufacturing method 1 can begin to make volume towel M.

And this initial setting is handled (S1) and is carried out light sensor to detect processing (S100), detects having or not of towel reel R (sheet material S).In addition, omit setting in the early stage among Figure 11 and handled the light sensor detection processing marks such as " S100 " that is implemented in (S1).With reference to Figure 12 light sensor processing (S100) is described at this.

Figure 12 is that the expression light sensor is handled the flow chart of (S100).Light sensor is handled (S100) and is at first launched infrared ray by luminescence unit 120a to target object, adopt light receiving unit 120b to receive this reflection ray (S31) simultaneously, this light receiving unit 120b judges the whether overshoot value of light income (colour gamut value) above (S32) of received reflection ray.

The result is in the processing of S32, and light income is judged to be outside setting (colour gamut value) above the time (S32:YES), and there be (with reference to Fig. 8 (b)) in sheet material S on transport path, can make volume towel M, returns in the processing of S1 and implements other treatment steps.

In the processing of S32, when light income is judged as and wants little than setting (colour gamut value) (S32:NO), there be not (with reference to Fig. 8 (c)) in sheet material S on transport path, this time be not have towel reel R in the volume tissue manufacturing method 1; Have only an axle core (cylinder rotary shaft Ra) of peeling off with the coupling part of the terminal of sheet material S to exist; Or towel reel R existence, but the first end parts of sheet material S correctly is not configured on the head roll 23.

Therefore, this time (S32:NO) carry out and to report processings (S33), as mentioned above, in the time of the LCD4b warning, loudspeaker 88 sound that gives a warning is warned the user to carry out the replacing of towel reel R, or is reconfigured the first end position of sheet material S.In addition, after reporting processing (S33) and carrying out, before loam cake 3 is unlocked, handle being repeated to carry out.

The flow chart that returns Figure 11 describes.Initial setting is handled (S1) as mentioned above, can judge and adopt light sensor to handle exist (S32:YES) that (S100) confirms sheet material S, and excess load detects processing (with reference to Figure 10) not to be had effective the time, towel reel R exists, sheet material S does not have incoming terminal (perhaps peeling off does not appear in the coupling part of the terminal of sheet material S and axle core), and the tip of sheet material S is correctly disposed, and therefore after carrying out other processing, transfers to S2 and handles.

At this relevant count value C is described.Count value is the quantity of the manufacturing volume towel that is set by the user.When being set at the single pattern by 2d, press when starting button 4a, this count value is set to 1, begins to make volume towel.Make during the volume towel, even operation start button 4a once more, count value is not increased yet.Finish a silver lap towel and when discharging, the numerical value of this count value C subtracts 1, can be once more by starting the beginning that button 4a indication is made.

And in the continuous mode,, can start button 4a by 10 times at most even during making volume towel, set the quantity of making volume towel.Finish a silver lap towel and when discharging, the numerical value of this count value subtracts 1, this respect is with pattern is identical separately.This count value, correspondence are pressed and are started button 4a starting interruption routine aspect, are remembered by the register of CPU71.This processing was subjoined with reference to Figure 14 later stage.

The processing of S2 is to confirm that count value C that register remembers whether more than or equal to value 1 (S2), when count value C is little than 1 (S2:NO), carries out respectively processing (S3).Each is handled (S3) and carries out the expression control that (for example rolling up the manufacturing quantity of towel M or the length of sheet material S etc.) or LCD4b are handled in the setting of being implemented by various buttons 92 (with reference to Fig. 3).After carrying out respectively processing (S3), transfer to S2 and handle.

During S2 handled, the value of count value C existed by the user and indicates the cause of making volume towel during more than or equal to value 1 (S2:YES), begins to make volume towel M, carries out the later processing of S4.

At this moment, CPU71 at first drives supply motor 81a, and the rotation of head roll 23 (with reference to Fig. 7) causes sheet material S to begin to be drawn out of (S4) by towel reel R.Sheet material S is sent to supply part 20 to water spray part 42 (with reference to Fig. 4).

The processing of S5 is transferred in the extraction action beginning back (S4) of sheet material S, and head roll 23 confirms whether implement 2 rotations (S5) by this rotation beginning, this rotation number is carried out standby (S5:NO) till arriving 2 times.And the affirmation of this head roll 23 is carried out (with reference to Fig. 6 (b)) by rotary inductive sensor 27 as mentioned above.In addition, volume tissue manufacturing method 1 that should use-case is set at head roll 23 rotations 2 times, is arrived the nozzle 42c (with reference to Fig. 4) of water spray part 42 by the tip of supplying with the sheet material S that part 20 hangs down.

So, in the processing of S5, when head roll 23 is judged as 2 rotations (S5:YES), the tip of sheet material S arrives the nozzle 42c of water spray part 42, begins to drive jet pump 83a, by nozzle 42c water spray (S6).Like this can be not lavishly to the sheet material S of the transport path that passes through water spray part 42 water spray.

Beginning is (S6) after the action of the water spray of sheet material S, transfers to the processing of S7, and head roll 23 confirms whether implement 4 rotations (S7) by this rotation beginning, this rotation number is carried out standby (S7:NO) till arriving 4 times.And volume tissue manufacturing method 1 that should use-case is set at head roll 23 rotations 4 times,, is arrived on the conveyer belt 51 of shaped portion 50 (with reference to Fig. 4) by water spray part 42 by the tip of supplying with the sheet material S that part 20 hangs down.

So, in the processing of S7, when head roll 23 is judged as 4 rotations (S7:YES), the tip of sheet material S arrives on the conveyer belt 51 of shaped portion 50, begins to drive and carries motor 85a, begins to rotate conveyer belt 51 (S7).Shown in Figure 13 (a), the sheet material S that arrives on the conveyer belt 51 by water spray part 42 can be delivered in the transport path of shaped portion 50 like this, prevention sheet material S is folded to form to carry on conveyer belt 51 and stops up or cacoplastic reason.

Beginning feeding sheets S transfers to S9 and handles to shaped portion 50 backs (S8), and head roll 23 confirms whether implement n rotation (S9) by this rotation beginning, this rotation number is carried out standby (S9:NO) till arriving n time." n " this n time rotation is based on the rotary switch 2e that is operated attached panel 2c by the user, the value that the length of the sheet material S of setting is calculated.Volume tissue manufacturing method 1 that should use-case is to set sheet material S length by 180mm till 480mm by the interval of 30mm, and the outer perimeter of head roll 23 approximately is the cause of 30mm as mentioned above, and the value of rotation number " n " is set to 6～16 integer value.

Therefore, in S9 handles, when rotating for n time during head roll 23 is judged (S9:YES), sheet material S by the set length of user is pumped end, the driving (S10) that stops supply motor 81a, jet pump 83a and carry motor 85a, end is extracted sheet material S out by towel reel R, to sheet material S water spray and every work of sheet material S tip being sent to shaped portion 50.

Like this, sheet material S is retained on the transport path that arrives shaped portion 50 (with reference to Fig. 4) by supplying with part 20 and water spray part 42.In addition, in the processing of S9, when the number of revolutions n of head roll 23 was fractional value (for example " 6 "), shown in Figure 13 (a), the tip of sheet material S stopped near the inlet of shaped portion 50; When number of revolutions n was big numerical value (for example " 16 "), sheet material S was imported into the transport path interior (with the corresponding surface of protecting cover 22) of shaped portion 50, and this tip is formed volume towel nuclear.

The extraction actions of sheet material S etc. finish back (S10), drive severing motor 82a and make cylinder knife 32 rotations and dead knife 33 severing sheet material S (S11) simultaneously.Then, stop the driving (S12) of severing motor 82a, transfer to the processing of S13.

(S11 S12), begins to carry motor 85a to make conveyer belt 51 rotations once more behind the severing sheet material S, in the time of along the transport path feeding sheets S of shaped portion 50 (S13), drive reverse motor 86a and make reverse conveyer belt 53 rotations, S is rolled into tubular with sheet material, begins to form volume towel M (S14).In addition, reverse conveyer belt 53 is shown in Figure 13 (b), and when oppositely moving with 51 one-tenth of conveyer belts, the translational speed Vr1 of this reverse conveyer belt 53 slightly equals the translational speed Vc1 (Vr1=Vc1) of conveyer belt 51.

When the processing of S13 and S14 is begun, sheet material S shown in Figure 13 (a) the at first rotation by conveyer belt 51 is sent to the rear portion of carrying road direction (Figure 13 (a) left to), by and the corresponding surface of cover 52 between, this tip is split into volume towel nuclear, afterwards, be transported to again and the corresponding surface of reverse conveyer belt 53 between.

The corresponding surface of reverse conveyer belt 53 and conveyer belt 51 mutually oppositely moves with about equally speed shown in Figure 13 (b).Therefore, the sheet material S that arrives between the corresponding surface is the center with volume towel nuclear, and shown in Figure 13 (b), the downside that is tilted the 52b of portion is kept, and is rolled into tubular.Do not need on the result as original volume towel device, guarantee sheet material S is rolled into the processing path (conveyer belt length) of tubular, can shorten the conveyer belt length of reverse conveyer belt 53 and conveyer belt 51, make shaped portion 50 miniaturizations, seek to roll up all miniaturizations of tissue manufacturing method 1.

In addition, because the translational speed Vr1 of reverse conveyer belt 53 and conveyer belt 51, Vc1 summary etc. can make obverse relative velocity reach maximum, and the transporting velocity of high speed sheet material S causes can seeking to shorten the curring time of rolling up towel M.

CHI-pulse and CUN-pulse being irregular or assembly error during for example because of manufacturing, the motor output characteristics is irregular etc., when the translational speed Vc1 that causes conveyer belt 51 is lower than the translational speed Vr1 of reverse conveyer belt 53 (Vc1＜Vr1=), rake 52b is towards the acclivitous cause of the throughput direction of sheet material S (Figure 13 (b) left to), in the time of also can preventing to roll up the towel shaping, sheet material S is towards the front portion (Figure 13 (b) is right-hand) of throughput direction adverse current.Therefore, there is no need to be strict with the translational speed unanimity of conveyer belt 51 and reverse conveyer belt 53, can reduce the management cost of CHI-pulse and CUN-pulse being irregular etc.

When the tubular that carries out sheet material S was shaped, sheet material S was accompanied by the increase of this drum diameter, and the inclination that is tilted the 52b of portion limits, and was transported to throughput direction rear portion (Figure 13 (b) left) in order at the downside of this rake 52b.At this moment, a sideway swivel cylinder 53a of reverse conveyer belt 53 (Figure 13 (b) left side) as mentioned above, is accompanied by the increase of drum diameter, can be along upwards (Figure 13 (b) top) escape of vertical slot 54a.

Therefore, thickness or the length that can ignore sheet material S is rolled into tubular.According to thickness and the length of suitable sheet material S, can make the volume towel of any size diameter.And the contact condition of sheet material S and reverse conveyer belt 53 can roughly certain cause, more with the backrush dynamics of increase and decrease sheet material S, makes the volume towel M of suitable (soft).

In addition, original volume tissue manufacturing method is to form tubular when sheet material S is transported to the throughput direction rear portion, because carry relation, and irregular on occurring easily being shaped.To this, the cause of tubular be kept and be rolled into to volume tissue manufacturing method 1 that should use-case can at the downside of rake 52b with sheet material S as mentioned above, can suppress to follow be shaped in the course of conveying irregular, with stabilized accuracy manufacturing volume towel M.

The processing of S15 is after the processing of S13, S14 begins, and after promptly conveyer belt 51 and reverse conveyer belt 53 begin rotation, confirms whether pass through Tn second (S15) by the tubular shaping beginning of sheet material S, process Tn carries out standby (S15:NO) till second.In addition, the start-up time of conveyer belt 51 and reverse conveyer belt 53 is in the time of inconsistent, and the elapsed time of Tn second can be the elapsed time of rising any one start-up time of conveyer belt 51 and reverse conveyer belt 53.

At this, be the time value that the tubular of sheet material S is shaped and is consumed " Tn " second, calculated based on the sheet material S length that is set by the user.Promptly the value of " Tn " is to be directly proportional with the value of above-mentioned " n (with reference to S9) ", the length of sheet material S long more (weak point), and the same with the value of number of revolutions " n ", the value of " Tn " also becomes (little) greatly, tubular shaping institute time-consuming elongated (weak point).

Therefore, in the processing of S15, when being identified second through curring time Tn (S15:YES), the tubular of sheet material S is shaped and finishes, volume towel M completion of processing.So, this time (S15:YES) stop reverse motor 86a, the rotation of reverse conveyer belt 53 is stopped (S16), volume towel M is discharged by shaped portion 50.

Tubular between the rotation corresponding surface of reverse conveyer belt 53 and conveyer belt 51 is shaped when finishing, shown in Figure 13 (a) and (b), continue the rotation of conveyer belt 51, its translational speed is kept this translational speed Vc2 (Vc2=Vc1), processing according to S16, just stop the rotation of reverse conveyer belt 53, its translational speed Vr2 be " 0 " (Vr2=0).Therefore, after tubular was shaped and finishes, sheet material S (promptly rolling up towel M) can discharge towards the throughput direction rear portion (Figure 13 (c) left side) of conveyer belt 51 shown in Figure 13 (c).

Therefore, there is no need as original volume tissue manufacturing method, after sheet material S tubular is shaped, carry (discharge) sheet material S with the relative speed difference between the corresponding surface (being Vc1-Vr1), can discharge sheet material S, the velocity of discharge of high speed sheet material S with the translational speed Vc2 (Vc2=Vc1) of conveyer belt 51.

In addition, volume tissue manufacturing method 1 that should use-case has disposed the cause of 2 motors that drives the conveying motor 85a of conveyer belt 51 and drive the reverse motor 86a of reverse conveyer belt 53, can stop the rotation of reverse motor 86a, conveyer belt 51 continues rotation, just stops the rotation of reverse conveyer belt 53.Therefore, when only adopting 1 motor to drive the structure of conveyer belt 51 and reverse conveyer belt 53, just stop the rotation of reverse conveyer belt 53, when just stopping reverse conveyer belt 53 by the transmission of the rotary power of this motor, the structure of removing the complexity such as identical of gear does not need other configuration, can oversimplify the structure of shaped portion 50, reduce the manufacturing cost of shaped portion 50.

In addition, the volume towel M that is discharged by shaped portion 50 is discharged into inclined guide plate 61 as mentioned above, can cause dual-purpose pallet cover 5 (with reference to Fig. 4) by this inclined guide plate 61.

The discharge of volume towel M finishes back (S16), and the driving that stops to carry motor 85a finishes the rotation (S17) of conveyer belt 51.A series of processing of processing volume towel M finish.

After the processing of S17 is implemented, implement light sensor and handle (S18), the sheet material S incoming terminal of towel reel R in the manufacturing of affirmation volume towel M, whether peel off the coupling part of the terminal of sheet material S and axle core.In addition, it is the cause of handling (S100) content identical (with reference to Figure 12) with effective light sensor in above-mentioned initial setting is handled (S1) that this light sensor is handled (S18), omits this detailed description.

Handle (S18) according to light sensor, when the existence of sheet material S is identified (S32:YES), can judge that towel reel R exists and peeling off does not appear in the coupling part of the terminal of this sheet material S and axle core.Therefore, can continue to make volume towel M, the value of count value C subtracts 1 (S19), returns the processing of S2.

In addition, stopping to drive conveying motor 85a is in the processing of S16, and after the driving of reverse motor 86a was stopped, the time of process appointment was implemented.In should use-case, the time of this appointment be approximately 1 second.

The interruption routine that is activated when illustrating that below with reference to Figure 14 starting button 4a is pressed.

When starting button 4a and being pressed, the setting of affirmation mode alternation switch 2d be " single " (pattern 1) or " continuously " (pattern 2) (S41).When being set to " continuously " (pattern 2) (S41:NO), confirm that whether present count value C is at (S42) more than 10.When count value C is littler than 10 (S42:YES), count value C increases by 1 (S43), is returned by this routine.In S42 handled, the value of count value C was more than 10 the time, is returned by this routine.

In the processing of S41, when mode altering switch 2d is set to " separately " (pattern 1) (S41:YES), confirm whether count value C is 0 (S44).When count value C is 0 (S44:YES), count value C is returned by this routine as 1 (S45).In the processing of S44, when count value C is not 0, return by this routine.

The following replacing method of towel reel R of the volume tissue manufacturing method 1 of the relevant said structure of explanation.When changing towel reel R, at first make progress (above Fig. 4) opens loam cake 3, and the towel reel R (cylinder rotary shaft Ra) that reel preservation part 10 is preserved is by main frame 2 inner taking-ups.Then new towel reel R is put into main frame 2, this towel reel R (cylinder rotary shaft Ra) preserves part 10 (support groove 12) by reel and preserves.

At this, the axle of loam cake 3 is fixed on the rear portion (Fig. 4 right side) of main frame 2; Reel is preserved part 10 and is configured in main frame 2 front portions (Fig. 4 left side).Therefore, when changing towel reel R, as shown in Figure 4, even loam cake 3 be semi-open state, also can wide-angle open the front portion of main frame 2, and there is the working space of sufficient replacing towel reel R the top (Fig. 4 upside) of guaranteeing reel preservation part 10.Even the narrow space of the top of loam cake 3 can not the complete opening loam cake 3 the time, also can carry out more changing jobs of towel reel R swimmingly, finally can improve the free degree that the place is set of volume tissue manufacturing method 1.

After towel reel R was kept at reel and preserves part 10, R can extract sheet material S out by this towel reel, and the tip of sheet material S is arranged on the supply platform 21 (head roll 23) of supplying with part 20.At this, supplying with part 20 is to be configured near the peristome of main frame 2, preserve the rear portion (Fig. 4 right side) of part 10 than reel near main frame 2, the tip of sheet material S is set to when supplying with part 20, this is provided with work and can is observed and be carried out by the front portion (Fig. 4 left side) of main frame 2, finally can adjust really and like a cork.

Sheet material S closes loam cake 3 after being set to and supplying with part 20, and main frame 2 opening portions are sealed.Cause the cylinder 25 of exerting pressure that the inboard disposed of loam cake 3 to pass through pressure, sheet material S is pressed onto on the head roll 23 of supplying with part 20, and the idle running of the cylinder 25 that prevents to exert pressure is when can positively supply sheet material S, towel reel R is built in main frame 2 and the loam cake 3, and this changes end-of-job.

The result is in the time of the replacing of towel reel R, and the first end parts of the sheet material S that is extracted out by towel reel R is placed on the head roll 23, as long as close loam cake 3, just can enter the possible state of sheet material S conveying.Therefore, sheet material S is pressed onto the volume tissue manufacturing method of the type on the cylinder as original the configuration by spring, it is unwanted that one hand is held the complex work of partly carrying out the setting of sheet material S of exerting pressure, and can simplify the work that is provided with of sheet material S, and improves the replacing operating efficiency of towel reel R.

Such as described above, according to volume tissue manufacturing method 1 that should use-case, the structure of loam cake is that the axle with forward part is the cause that the center can rotate freely, and can ignore thickness or the material of sheet material S, positively is shaped.

More than, based on application examples explanation the present invention, but the present invention is defined in above-mentioned application examples, can do the improvement change of various kinds in not exceeding the intent of the present invention scope, and this is to implement easily.

For example, should the volume tissue manufacturing method of use-case in, cover 52 is the structures of being exerted pressure to conveyer belt 51 by coil spring 52e; Also can replace coil spring 52e with the weights of flat spring or suitable weight exerts pressure to conveyer belt 51.
