In more detail, as shown in Figure 2, tension adjustment mechanism 54 comprises: the driven roller 56 of conveyor surface ply of paper body paper A and being used for is adjusted the rotary speed guiding mechanism (not shown) of the rotary speed of this driven roller 56.Tension adjustment mechanism 54 also comprises and is adjacent to the set pushing roller 60 of driven roller 56, to stipulating clamp pressure by driven roller 56 and the facial tissue layer body paper A effect between the pushing roller 60.As shown in Figure 3, pushing roller 60 is made up of 5 rollers, and these 5 rollers have the axial length shorter than the axial length of driven roller 56 respectively, and is arranged in roughly linearity along the axial length of driven roller 56.Whereby, can prevent from again on facial tissue layer body paper A, to produce wrinkle both being enough to prevent that the regulation clamp pressure that skids between facial tissue layer body paper A and the driven roller 56 from putting on facial tissue layer body paper A.
On the other hand, as shown in Figure 4, tension change testing agency comprises: facial tissue layer body paper A around the dancer of hanging 62; Gear/rackwork 64, it is formed by pinion 64a with the tooth bar 64b of this pinion 64a engagement, this pinion 64a be located at dancer 62 each hold so that dancer 62 is supported in the mode that moves of can rolling on its axis approximate right angle direction; And piston/cylinder mechanism 66, this piston/cylinder mechanism 66 loads dancer 62 in the mode with the equalization of strain that acts on dancer 62, and this tension force that acts on dancer 62 is that the body paper by the body paper of the production line upstream side of this dancer 62 and line downstream side acts on this dancer 62.This dancer 62 from the moving of balance reference position, detect by encoder (not shown), detection signal sends to the rotary speed guiding mechanism 58 of driven roller 56.And then, as shown in Figure 2, production line upstream side and line downstream side at dancer 62 is provided with guide roller 68,69 respectively, so that make the direction of the supply almost parallel of the direction of the supply and the body paper of the line downstream side of relative dancer 62 of body paper of the production line upstream side of relative dancer 62.
The guide roller 69 in this downstream is to rotate freely roller, on its side face around hanging the body paper of advancing, by advancing of body paper, with roughly identical with the gait of march of body paper speed rotation, the speed detector 79 that detects this rotary speed is installed on the equipment this guide roller by the friction of body paper.
Facial tissue layer body paper A is roughly 180 ° to dancer 62 around hanging angle.And then piston/cylinder mechanism 66 acts on the tension force of dancer 62 based on production line upstream side body paper and line downstream side body paper, can adjust its loading force.
In the manufacturing installation 10 of single face corrugated board, the following describes its effect with above formation.
At first, facial tissue layer body paper A and the core paper layer body paper B driven roller 56 that pasted tissue machine 16 by single face transfers out from separately driven rolls 18.At this moment, detect the tension force on facial tissue layer body paper A and core paper layer body paper B, take place, and based on this detected value, adjust the reduction amount of the rotary speed of driven rolls, coarse regulation tension force by the brake gear on the driven rolls that is located at separately.Whereby, be applied for the required basic tension force of generation that prevents wrinkle at facial tissue layer body paper A and core paper layer body paper B on separately.Next, in splicer 14, facial tissue layer body paper A and core paper layer body paper B at this moment, are produced the change of tension force by suitably splicing on body paper.Next, facial tissue layer body paper A is preheated device 15 preheatings.
Then, facial tissue layer body paper A and core paper layer body paper B arrive tension change absorption device 50 via preheater 15, guide roller 75.Here, detect the change of the tension force that on facial tissue layer body paper A, produces by near the tension change testing agency the upstream side that is arranged at single face subsides tissue machine 16 52, and change based on the tension force that detects, adjust facial tissue layer body paper A pastes body paper transporting velocity from tissue machine 16 to single face, be adjusted at single face with this and paste the tension force that near tissue machine 16 facial tissue layer body paper A upward produce, the change of tension force converges in the certain limit.
More particularly, if the tension change that produces on body paper when splicing or when running well must surpass certain limit, then dancer 62 moves by the pinion 64a pinion rack 64b that is located at two ends, and it is mobile to roll from the benchmark equilbrium position.For example, when tension force was higher than certain limit, in Fig. 5, moved in the left side of dancer 62 on drawing.Encoder (not shown) detects this and moves, and transmits control signal to driven roller 56 from encoder.Based on this control signal, driven roller 56 is adjusted its rotary speed, adjusts the transporting velocity of body paper A.When between facial tissue layer body paper A is by driven roller 56 and the pushing roller 60 that is provided with near driven roller 56, cut apart roller not produce on the body paper under the situation of wrinkle for 5, clamp pressure with regulation pushes driven roller 56, do not skid so can not produce between facial tissue layer body paper A and driven roller 60, facial tissue layer body paper A sends with the transporting velocity driven rolls 56 corresponding to the rotary speed of driven roller 56.
Become the transporting velocity of the benchmark of driven roller 56,, determine to become the transporting velocity of the driven roller of benchmark based on the rate signal that detects from the speed detector 79 of the rotary speed of the guide roller 69 in downstream.
For example, the rotary speed of driven roller 56 paste greater than single face tissue machine 16 the 1st corrugation driven roller 36 become the transporting velocity of benchmark the time, lax reduce of the tension force that on the body paper in the downstream of driven roller 56, produces because of on body paper, producing, on the other hand, the rotary speed of driven roller 56 paste less than single face tissue machine 16 the 1st corrugation driven roller 36 become the transporting velocity of benchmark the time, the tension force that produces on the body paper in the downstream of driven roller 56 increases because of the stretching that produces on body paper.The positive increase and decrease of this tension force that causes by driven roller 56, the change of the tension force that the upstream side at driven roller 56 is produced on body paper absorbs and carries out inching, as a result, can the change of tension force that single face pastes the body paper of tissue machine 16 vicinity be limited in the prescribed limit.
Moreover, by adjusting the loading force of the dancer 62 that piston/cylinder mechanism 66 causes, perhaps suitably regulate around the upstream side of the body paper that is hung on dancer 62 and the direction of the supply of downstream example, can adjust the tension value that produces on the body paper on the balance reference position by suitable selection guide roller 68,69 the position being set.Whereby, can suitably regulate the benchmark tension value of the benchmark of the change that becomes tension force.
Then, side suitably prevents the facial tissue layer body paper A of the change of tension force near single face pastes the upstream of tissue machine 16 like this, arrive single face via guide roller 77 and paste tissue machine 16, here, core paper layer body paper B forms the corrugated core paper layer of regulation, and on the corrugation top of core paper layer body paper B, be coated with paste by hang sticking with paste mechanism, supply range ply of paper body paper A on the other hand, the core paper layer and the facial tissue layer body paper A that have been coated with paste are bonding.So, core paper layer and facial tissue layer body paper A by putting on the tension force of facial tissue layer body paper A, do not apply clamp pressure and by bonding.Here,,, carry out good bondingly, can prevent the warpage of single face corrugated board D simultaneously so can prevent to produce skew between facial tissue layer body paper A and the core paper layer because the upstream side that pastes tissue machine 16 at single face prevents the change of tension force.In addition, can prevent to be printed on the variation of the sign spacing on the single face corrugated board D, so can avoid the harmful effect of operation is for example cut off in production management or next procedure.
Then, the single face corrugated board D that has finished delivers to and transfers conveyer 71 via batching conveyer 70, places the wait state of preparing printing process or cutting off next procedures such as operation here.
As above, by the change of the tension force that prevents from body paper, to produce, can the good single face corrugated board D of workmanship.
Though detailed explanation embodiments of the present invention, can in the scope of the present invention described in claims, carry out all changes, correction.
Though in embodiment, the single face subsides tissue machine of the type of bonding plane ply of paper and core paper layer is an object only to apply tension force on facial tissue layer, the occasion that tension change absorption device is set in facial tissue layer one side is illustrated, but be not limited thereto, for example the single face by the bonding type of clamp pressure of the prior art being pasted tissue machine also can be suitable for, in this occasion, if particularly tension change absorption device is set in core paper layer side, then by preventing the change of the tension force in splicing pattern or the normal operation mode, make excessive tension force can not put on the core paper layer, can prevent effectively that whereby the corrugation of core paper layer from breaking or the corrugation collapsing.
As more than explain, if with the manufacturing installation of corrugated board of the present invention, then can tackle rapidly and reliably the change of the tension force that on body paper, produces.And then, by carrying out the good bonding of core paper layer body paper and facial tissue layer body paper reliably, can make high-quality corrugated board.
Tension change absorption device of the present invention can prevent the change of the tension force that particularly produces on the facial tissue layer at body paper, and can need not significantly transform or change and pack into as a unit the manufacturing installation of existing corrugated board.
