That is to say, step-up transmission mechanism 20 transmits slightly more quickly by shut-off mechanism 10 and cuts offIndividual sheets FP.
First, use the operator of variable cut-out size folding apparatus 100 that the cut-out size of individual sheets FP is setFor 813mm. As mentioned above, in the present embodiment, the circumferential lengths of shut-off mechanism 10 is configured to cut off with maximumThe length that size is equal, therefore establishes the circumferential speed of the supply rate of supplied continuous paper W and cut-out cylinder 11Be decided to be and equate to make the cut-out constant dimension of individual sheets FP at 813mm.
Fig. 4 illustrates that wherein step-up transmission mechanism 20 cuts off the view of the example of size transmission individual sheets with maximum.In Fig. 4, dotted line α represents " length of the half cycle of folding cylinder 40 ", and dotted line β 1 represents " to cut off size with maximumThe length of the individual sheets FP cutting off ", dotted line γ represents " interval of being caused by the effect of step-up transmission mechanism 20 ".Note, because the position of individual sheets FP3 is the position of the individual sheets FP3 in the time being cut off by cut-out cylinder 11 justPut, therefore individual sheets FP3 is without undergoing the effect of step-up transmission mechanism 20.
As shown in Figure 4, step-up transmission mechanism 20 by cut-out be of a size of 813mm individual sheets FP1, FP2,FP3 ..., FPN is sent to lower folding connecting gear 30. Now, individual sheets FP is with faster than transfer rate before cutting offCut-out after speed transmission (in other words, cut off after acceleration), therefore step-up transmission mechanism 20 is at adjacent single pageBetween paper FP, form interval, and this interval is corresponding to cutting off front transfer rate and cutting off the poor of rear transfer rate.But during maximum is cut off size, the difference of speed is less, the interval therefore being formed by step-up transmission mechanism 20 canTo ignore.
In the time that individual sheets FP1 is above sent to lower folding connecting gear 30 by step-up transmission mechanism 20, lower folding transmissionMechanism 30 is resisted against folding cylinder 40 with the speed identical with the circumferential speed of folding cylinder 40 by individual sheets FP1Retainer 42 on (with reference to Fig. 5).
At individual sheets FP1, against in retainer 42, the contact pin apparatus 41 of folding cylinder 40 operates, andFolding cylinder 40 is collected individual sheets FP1. When having turned under the state that folding cylinder 40 is collected at individual sheets FP1When half-turn (rotating next the butt position to retainer 42), FP1 is similar to individual sheets, step-up transmission mechanism20 are resisted against the individual sheets FP2 transmitting via lower folding connecting gear 30 on retainer 42.
Fig. 5 illustrates that folding cylinder 40 wherein collects the example of individual sheets subsequently during maximum is cut off sizeView. As shown in Figure 5, " maximum cut off size " being represented by dotted line β 1 with represented by dotted line γ " by step-up transmissionThe interval that the effect of mechanism 20 causes " the pattern length " length of the half cycle of folding cylinder 40 that equals to be represented by dotted line αDegree ". Therefore,, if once locate, the maximum of being collected by folding cylinder 40 is cut off the individual sheets of sizeFP must be collected against the state of retainer 42 with the forward edge along direct of travel, can make thus folding cylinderPeriodicity in 40 is collected operation and is accurately carried out. In other words, can produce high-quality signature.
Then, hold paper roll 50 grippings in the month and wherein collect the paper group of the paper of any amount, and will therefore formSignature be sent to and be arranged on the (not shown) such as the stacking mechanism in downstream.
The operation of variable cut-out size folding apparatus 100 during maximum is cut off size has more than been described. Next, willBe described in the minimum operation of cutting off variable cut-out size folding apparatus 100 during size. In the time changing cut-out size, askTopic is, the girth of folding cylinder 40 can not change. That is to say the cut-out size of the individual sheets FP meaning that shortensAlong the length of direct of travel and shorten, this so that mean that the arrival interval of individual sheets FP also inevitably will becomeShort. Therefore roll than the folding of the half-turn of having advanced the head edge position that, is sent to the individual sheets FP of folding cylinder 40Cylinder quickly arrive, can not thrust in suitable acupuncture position thus individual sheets FP before direct of travelEdge side. Thereby, according in the variable cut-out size folding apparatus 100 of present embodiment, be intended to by utilize byThe difference of the transfer rate causing in step-up transmission mechanism 20 overcomes this problem.
First,, owing to becoming the minimum size of cutting off, the circumferential speed that cuts off cylinder 11 increases. Particularly, due toLarge size (813mm) and the minimum Length Ratio cutting off between size (546mm) of cutting off, cuts off circumferentially speed of cylinderDegree is changed into 1.5 times. That is to say, cut off with the speed of 1.5 times, make to cut off size and be configured to minimumCut off size. And the circumferential speed of folding cylinder 40 and the circumferential speed of holding paper roll 50 in the month increase simultaneously, withThe speed increase of cutting off cylinder 11 matches.
Now, Fig. 6 is the looking of example that illustrates that wherein step-up transmission mechanism 20 cuts off size and transmits individual sheets with minimumFigure. In Fig. 6, dotted line α represents " length of the half cycle of folding cylinder 40 ", and dotted line β 2 represents " to cut off chi with minimumThe length of the individual sheets FP of very little cut-out ", dotted line γ represents " interval of being caused by the effect of step-up transmission mechanism 20 ".
As shown in Figure 6, step-up transmission mechanism 20 by cut-out be of a size of 546mm individual sheets FP1, FP2, FP3,FP4 ..., FPN is sent to lower folding connecting gear 30. As mentioned above, step-up transmission mechanism 20 cuts off chi in minimumTransfer rate during very little becomes in maximum cuts off 1.5 times of transfer rate during size. That is to say, as Fig. 6Shown in, compared with during maximum cut-out size, individual sheets FP1, FP2, FP3 and FP4 shorten and single pageIt is large that interval between paper FP becomes.
In the time that individual sheets FP1 is above sent to lower folding connecting gear 30 by step-up transmission mechanism 20, lower folding transmissionMechanism 30 is resisted against folding cylinder 40 with the speed identical with the circumferential speed of folding cylinder 40 by individual sheets FP1Retainer 42 on (with reference to Fig. 7).
At individual sheets FP1, against in retainer 42, the contact pin apparatus 41 of folding cylinder 40 operates, andFolding cylinder 40 is collected individual sheets FP1. When having turned under the state that folding cylinder 40 is collected at individual sheets FP1When half-turn (rotating next the butt position to retainer 42), FP1 is similar to individual sheets, step-up transmission mechanism20 are resisted against the individual sheets FP2 transmitting via lower folding connecting gear 30 on retainer 42.
Fig. 7 illustrates that folding cylinder 40 wherein collects the example of individual sheets subsequently during minimum is cut off sizeView. As shown in Figure 7, " minimum cut off size " being represented by dotted line β 2 with represented by dotted line γ " by step-up transmissionThe interval that the effect of mechanism 20 causes " the pattern length " length of the half cycle of folding cylinder 40 that equals to be represented by dotted line αDegree ". Therefore, because the variable cut-out size folding apparatus 100 according to present embodiment adopts by step-up transmission machineStructure 20 increase cut off after the speed of individual sheets FP to produce the structure at the interval corresponding with the difference of speed, therefore beforeThe front end along direct of travel with individual sheets FP subsequently along the front edge of direct of travel of individual sheets FPDistance between edge equals the length of the half cycle of folding cylinder 40, even if make thus to change cutting off size,Also can fix the suitable head edge position of individual sheets FP.
In addition,, because the length of the individual sheets FP being collected by folding cylinder 40 shortens, therefore held in the month paper dress by grippingThe middle position of putting the individual sheets FP in 51 changes. Therefore, thrust blade apparatus 43 is according to cutting off chi from maximumChange during very little during extremely minimum cut-out size changes phase place.
Now, if the phase change of thrust blade apparatus 43 only, thrust blade apparatus 43 with hold paper apparatus 51 in the monthBetween synchronously there is misalignment. In other words,, while having there is the thrust blade operation when thrust blade apparatus 43, hold paper in the monthInstall 51 no-fix in the position relative with thrust blade apparatus 43. Therefore can not carry out by holding paper apparatus 51 in the monthThe operation of gripping paper group. Thereby, be configured to comprise hold in the month paper apparatus 51 hold in the month paper roll 50 change phase place with thrustThe change of the phase place of blade apparatus 43 is synchronous. Therefore can make folding cylinder 40 collect the individual sheets of any amountFP, can make the thrust blade apparatus 43 through phase change operate, and can make operatedThrust blade clamps by holding paper roll 51 in the month. Like this, variable cut-out size folding apparatus 100 produce signature and towardsBe arranged on the (not shown) such as the stacking mechanism in downstream and transmit the signature producing.
The operation of variable cut-out size folding apparatus 100 during minimum is cut off size has more than been described.
