The present invention relates to a kind of feedway of folding machine; Wherein, This used for folding machine in rotary press with the 1st continuous paper group and the 2nd continuous paper group overlapping send between sawtooth body and the folding body and make newspaper folding card; Said the 1st continuous paper group through a plurality of continuous papers are overlapping and longitudinal folding by the folding set square be that 1/2nd breadths obtain; Said the 2nd continuous paper group be by dimension width with longitudinal folding through said folding set square after the identical a plurality of continuous papers of width dimensions of the 1st continuous paper group constitute; And this folding machine has at least one and is provided as said the 2nd continuous paper group is directed to the conveying roller with said the 1st continuous paper group position overlapped, and drives at least one conveying roller rotation in the said conveying roller.
Background technology
The newspaper folding card that utilizes rotary press to make; Usually make according to the severing size of predetermined folding machine confirm a plurality of continuous papers of the two page width degree that the lengthwise dimension of continuous paper is printed overlapping the folding set square through folding machine; And through this folding set square by longitudinal folding be 1/2nd breadths parallel with direct of travel, thereby form one page breadth, promptly be discharged to the continuous paper group of the breadth (below be expressed as roll over obedient breadth) of the folding card on the belt conveyor of folding machine of back narration.And; Said continuous paper group is directed to the severing position between sawtooth body and the folding body; Serrated knife and the direct of travel severing vertically of continuous paper that utilization is installed on the sawtooth body are predetermined severing size; Again through folding body and folding roller by lorizontal folding, thereby made the newspaper folding card (below be expressed as the obedient A of folding) that is discharged to folding four foldings on the belt conveyor through transport fan.
On the other hand; Overlapping a plurality of continuous papers of confirming the obedient breadth of said folding that the lengthwise dimension of continuous paper is printed according to the severing size of predetermined folding machine as the continuous paper group; And be directed to the severing position between sawtooth body and the folding body; Serrated knife and the direct of travel severing vertically of continuous paper that utilization is installed on the sawtooth body are predetermined severing size; Again through folding body and folding roller by lorizontal folding, thereby made other newspapers folding cards (below be expressed as the obedient B of folding) that are discharged to folding two foldings on the belt conveyor through transport fan.
These newspaper folding cards were respectively independent the making in the past.But; Following mode is adopted in expectation recently; A plurality of continuous papers of said overlapping two pages of breadths longitudinal folding through the folding set square be that 1/2nd breadths are as the obedient breadth of folding; Form the continuous paper group (below be expressed as continuous paper group A) of the obedient A of folding; Make a plurality of continuous papers of the obedient breadth of folding overlap to form the continuous paper group (below be expressed as continuous paper group B) of the obedient B of folding, make continuous paper group A overlapping with continuous paper group B and make the both side edges of each continuous paper group consistent then, at first formation merging continuous paper group (below be expressed as continuous paper group E).And; Be directed to the severing position between sawtooth body and the folding body to said continuous paper group E; Serrated knife and direct of travel severing vertically that utilization is installed on the sawtooth body are predetermined severing size; Carry out horizontal folding by the folding body again, make the obedient A of folding and the obedient B of folding thus along the overlapping folding newspaper folding of same lateral broken line card (below be expressed as the obedient E of folding).
In order to make the obedient E of said folding; Need respectively according to different paper path overlaps and respectively according to a side or both sides among the continuous paper group A of different paper route guidances and the continuous paper group B as continuous paper group E, and be transported to the lap position through the feedway that folding machine has.
But the feedway of folding machine makes the continuous paper group keep batching angle with supported rotatable one or more conveying rollers and contacts, and changes its direct of travel thus.Therefore; The continuous paper group of being carried is in the process of advancing along the paper path of feedway; Because the stretching in that this direct of travel produces perhaps owing to the rotational resistance of conveying roller, makes tension force weaken; Continuous paper moves and produces along its Width in traveling process and crawls, so there is the problem that diminishes the obedient quality of folding.
On the other hand, as the feedway of folding machine, proposed Japanese reality and opened the disclosed technology of clear 62-53279 communique (below be called patent documentation 1).
Patent documentation 1 is provided with rotating driving device on the conveying roller of feedway, to continuous paper suitable tension force is provided.
For utilizing the folding set square longitudinal folding is the continuous paper group A of 1/2nd breadths; Patent documentation 1 makes the inboard continuous paper of the radial direction that contacts with the conveying roller periphery that is provided with rotating driving device and be directed and from the continuous paper in the radial direction outside that said conveying roller periphery is directed through a plurality of continuous papers; Be connected in one by the folding part that forms via the folding set square, so can tension force to a certain degree be provided to each continuous paper that constitutes continuous paper group A.
But; In folding machine; For example; Since usually above the folding set square the spherical folding set square of configuration, folding set square surface and horizontal surface are formed the angle of inclination big, at a variety of causes such as folding set square of the more microscler shape of direct of travel configuration of continuous paper, the elongated trend of transport path of feedway appears recently.Therefore, the continuous paper group be transferred that device carries during because that the tension force that the stretching that produces at its direct of travel causes weakens is more obvious, and the situation that between each continuous paper, is involved in air layer increases.
Especially the continuous paper group B that overlaps to form for a plurality of continuous papers that will roll over obedient breadth; The continuous paper that the radial direction that contacts with the conveying roller periphery and be directed is inboard and separate from the continuous paper in the radial direction outside that the conveying roller periphery is directed through a plurality of continuous papers; Arbitrary side's lateral margin of Width does not all have closure; So in course of conveying; That is, in the process of in the process that continuous paper group B advances, perhaps between conveying roller and conveying roller, advancing, between each continuous paper, be involved in air layer extremely easily between pinch roll and conveying roller.And, even keeping batching the angle with conveying roller, continuous paper group B contacts, the air layer between each continuous paper that is involved in also can't only be discharged from the both side edges of continuous paper group B fully.
Therefore; Owing to residue in the air layer between each continuous paper; Between equitant each continuous paper, the transmission of the power that is formed by mutual friction force is minimum, for example; The suitable tension of the continuous paper that the radial direction that said patent documentation is 1 disclosed, contacting guiding with the conveying roller periphery by offering of forming of the driving of conveying roller is inboard, can not useful effect at the overlapping continuous paper of the outside of this continuous paper order.
Therefore, can not suitable tension force be provided,, will diminish the obedient quality of folding sometimes so cause continuous paper in traveling process, to move and crawl along its Width to each continuous paper that constitutes continuous paper group B.
Summary of the invention
The present invention proposes for the problem that solves said prior art and exist, and its purpose is, a kind of feedway of folding machine is provided, and through to each continuous paper that constitutes the continuous paper group suitable tension force being provided, can preventing the continuous paper deflection and crawls.
In order to address the above problem; The feedway of the folding machine that the present invention relates to; This used for folding machine in the 1st continuous paper group and the 2nd continuous paper group overlapping send between sawtooth body and the folding body and make newspaper folding card; Said the 1st continuous paper group through a plurality of continuous papers are overlapping and longitudinal folding by the folding set square be that 1/2nd breadths obtain; Said the 2nd continuous paper group be by dimension width with longitudinal folding through said folding set square after the identical a plurality of continuous papers of width dimensions of the 1st continuous paper group constitute, and this folding machine has at least one and is provided as said the 2nd continuous paper group is directed to the conveying roller with said the 1st continuous paper group position overlapped; And at least one conveying roller that drives in the said conveying roller rotates
In the feedway of said folding machine, at least one conveying roller in the conveying roller of said driving is through making the different side face of external diameter adjacent and on the outer peripheral face of the scope that continuous paper touches, be provided with differential on the direction of principal axis.
Feedway according to the folding machine that the present invention relates to; Conveying roller is through making the different side face of external diameter adjacent and on the outer peripheral face of the scope that continuous paper touches, be provided with differential on the direction of principal axis; Keep batching in the continuous paper group that the angle contacts with conveying roller thus, touch the scope of the large-diameter portion of said conveying roller; For the scope of contact minor diameter part, the paper path increases, correspondingly each continuous paper by brute force by being pressed on the conveying roller surface.On the other hand; On the contrary in the scope of contact minor diameter part; It is weak to be pressed against the lip-deep power of conveying roller; The air layer that is involved between each continuous paper is powerful by between the continuous paper that is pressed in the lip-deep contact large-diameter portion of conveying roller from quilt, is expressed in the scope of the weak minor diameter part of contact pressing force the air layer disappearance between the continuous paper of contact large-diameter portion.Therefore, in the conveying roller large-diameter portion, continuous paper contacts each other, and the transmission of the power of carrying out being formed by friction force.So can suitable tension force be provided to each continuous paper that constitutes the continuous paper group, can prevent the continuous paper deflection and crawl.
The feedway of the folding machine that preferably the present invention relates to is in the feedway of the folding machine of said structure; Make two of driven conveying rollers mutual approaching; And at least one side's conveying roller and forms respectively at least one place of driven conveying roller and to batch the configuration that the angle contacts with the side surface of the 2nd continuous paper group with the surperficial maintenance of the opposing party through making the different side face of external diameter adjacent and on the outer peripheral face of the scope that continuous paper touches, be provided with differentially on the direction of principal axis.
Therefore, on the basis of above-mentioned effect, can also obtain the effect of the following stated.
For differential side's conveying roller is set on outer peripheral face; The quantity of continuous paper more for a long time in the continuous paper of the said conveying roller surface side far away that distance contacts through a plurality of continuous papers; Equitant continuous paper becomes liner, and the effect of in large-diameter portion, extruding air layer weakens.Therefore, when being involved in more air between the continuous paper, in large-diameter portion, can not extrude air layer fully, the transmission of the power that is formed by friction force is difficult to arrive from the conveying roller surface continuous paper of the said conveying roller of a distance surface side far away.Therefore; Near said side's conveying roller, other conveying roller is set; Make that keeping batching the angle with the different face of the 2nd continuous paper group mutually contacts; Can carry out the transmission of sufficient power to the continuous paper of the said side's conveying roller surface of a distance side far away from said other conveying roller thus, so can suitable tension force be provided to each continuous paper integral body that constitutes the continuous paper group.Therefore, can further improve the effect that prevents that continuous paper is partial to and is crawled.
And as optimal way, the large-diameter portion in the different side face of external diameter is with respect to the roughly balanced configuration of Width central authorities of continuous paper.
And, as optimal way, in the different side face of external diameter, large-diameter portion is identical with minor diameter part or littler than it with respect to the ratio of the direction of principal axis scope of minor diameter part.
And, as optimal way, the surface treatment that can be used to improve friction coefficient to the side face enforcement of the large-diameter portion in the different side face of external diameter.
According to these optimal ways, can not be partial in Width keep the advancing balance of tension force.

In the structure of above record, the feedway R that application of the present invention relates to constitutes not shown associated mechanisms such as comprising conveying roller R1～R3 and driver element thereof.
Below, position and the shape of conveying roller R1～R3 are described.
As noted earlier, the conveying roller R1 that is used for the 2nd continuous paper group W10 is directed to the position of not disturbing hypomere folding set square F11 is set at the position near the fore side framework, and is positioned at the below of pinch roll M1a, M1b.
Be used for to be directed to by the 2nd continuous paper group W10 from conveying roller R1 the conveying roller R3 of the direction that the paper path with the 1st continuous paper group W20 merges to approximate vertical below guiding; Be set at said conveying roller R1 roughly under, and be positioned at the top of pinch roll N2a, N2b.
Conveying roller R2 is located near the top of conveying roller R3.And conveying roller R2 is set to make the horizontal direction in axle center of its axle center and conveying roller R3 at interval less than the aggregate value of the radius of the radius of conveying roller R2 and conveying roller R3, and is positioned at and compares the position of conveying roller R3 away from said pinch roll N2a, N2b.Therefore, make from vertical direction roughly with conveying roller R3's and the 2nd continuous paper group W10 guiding of advancing of the mode that contact of the side face of a side of framework face-off contact for batching the angle with the opposition side side face maintenance of the side face of conveying roller R2 and the side framework face-off.
The side face of conveying roller R1 and R2 is such as shown in Figures 2 and 3 to be provided as in the direction of principal axis scope that the 2nd continuous paper group W10 contacts, and makes large-diameter portion X and minor diameter part Y replace adjacent shape.The radius of large-diameter portion X and minor diameter part Y roughly differs 1mm, and adjacent part constitutes differential.Large-diameter portion X is configured to roughly symmetrical with respect to the Width central authorities of the 2nd continuous paper group W10, in this embodiment, is configured to the paper web face with respect to the 2nd continuous paper group W10, is positioned near 4 positions of both ends that comprise the 2nd continuous paper group W10.Said large-diameter portion X is identical with minor diameter part Y or littler than it with respect to the ratio of the direction of principal axis scope of minor diameter part Y.And the side face of large-diameter portion X has been implemented the surface treatment that additional annular knurl line for example etc. is used to improve friction coefficient.
As shown in Figure 3, conveying roller R3 forms its side face does not have the identical roller of diameter on differential, the direction of principal axis.
Conveying roller R1, R2 and R3 make their circular velocity become the gait of march fast speed of beguine according to the 2nd definite continuous paper group W10 of the driving peripheral speed of said pinch roll M1a, M1b and N2a, N2b by not shown drive unit drives.And, preferably when rotary press is worked, their circular velocity is set at the suitable ratio in 103%～120% scope of gait of march of the 2nd continuous paper group W10.In addition; Said conveying roller R1, R2 and R3 are by the motor-driven that drives folding machine; Perhaps drive through suitable Poewr transmission mechanism, perhaps drive by motor special with the motor synchronous rotation that drives said folding machine by the motor that drives with the pinch roll of the motor synchronous rotation that drives this folding machine.
Below, the effect of this embodiment is described.
4 the continuous paper W11a, W11b, W12a, W12b that pass out to the 2nd continuous paper group W10 in downstream via pinch roll M1a, M1b are towards conveying roller R1.
During advance to the paper path of conveying roller R1, between 4 continuous paper W11a, W11b, W12a, W12b, get into air layer at the 2nd continuous paper group W10, form the state that produces minim gap from pinch roll M1a, M1b, and contact conveying roller R1.
On conveying roller R1 side face; Large-diameter portion X is adjacent with minor diameter part Y; Overlapping and conveying roller R1 keep batching among the 2nd continuous paper group W10 that the angle contacts, the scope of the large-diameter portion X of the said conveying roller R1 of contact; With respect to the scope of contact minor diameter part Y, each continuous paper W11a, W11b, W12a, W12b by brute force by being pressed on the conveying roller surface.On the other hand; In the scope of opposite contact minor diameter part Y; It is weak to be pressed against the lip-deep power of conveying roller, is involved in the air layer between each continuous paper W11a, W11b, W12a, the W12b, powerful by between the continuous paper that is pressed in the lip-deep contact large-diameter portion of conveying roller X from quilt; Be expressed in the scope of the weak minor diameter part Y of contact pressing force, the air layer between the continuous paper of contact large-diameter portion X disappears.Therefore, in conveying roller large-diameter portion X, continuous paper W11a, W11b, W12a, W12b contact each other, and the transmission of the power of carrying out being formed by friction force, so can suitable tension force be provided to each continuous paper.
,, advance to the 2nd circuitous continuous paper group W10 of the fore side of hypomere folding set square F11 via conveying roller R1 towards the conveying roller R3 that changes its direct of travel in order to merge with the 1st continuous paper group W20 that becomes outside grid face with folding folding part.In this traveling process, the tension force weakness of advancing of the 2nd continuous paper group W10 is involved in air layer simultaneously between 4 continuous paper W11a, W11b, W12a, W12b.And the interval ratio from conveying roller R1 to conveying roller R3 is long to the interval of conveying roller R1 from pinch roll M1a, M1b, between 4 continuous paper W11a, W11b, W12a, W12b, is involved in the more air layer easily.Contact part between each continuous paper reduces because of the air layer that is involved in, and the related each other property that is formed by friction force weakens.
Therefore, before changing the direct of travel of the 2nd continuous paper group W10 via conveying roller R3, near the conveying roller R2 making it and being configured in its upstream side keeps batching the angle and contacts.The face of the 2nd continuous paper group W10 contact conveying roller R2 is the face of opposition side of the face of contact conveying roller R3.
On the side face of conveying roller R2, R1 is identical with conveying roller, adjacent large-diameter portion X and the minor diameter part Y of being provided with.Therefore; At first; Keep batching the 2nd continuous paper group W10 that the angle contacts with conveying roller R2; With identical based on the effect of above-mentioned conveying roller R1, in the scope of the large-diameter portion X of contact conveying roller R2 scope with respect to contact minor diameter part Y, each continuous paper W11a, W11b, W12a, W12b by brute force by being pressed on the conveying roller surface.On the other hand; On the contrary in the scope of contact minor diameter part Y; The power of pushing the conveying roller surface is weak, is involved in the air layer between each continuous paper W11a, W11b, W12a, the W12b, and is powerful by between the continuous paper that is pressed in the lip-deep contact large-diameter portion of conveying roller X from quilt; Be expressed in the scope of the weak minor diameter part Y of contact pressing force, the air layer between the continuous paper of contact large-diameter portion X disappears.But the quantity that constitutes the continuous paper of the 2nd continuous paper group is not limited to 4 of said the 2nd continuous paper group W10, in graphic rotary press, can increase to 12.Like this; When the continuous paper that constitutes the 2nd continuous paper group was the 2nd continuous paper group W10 ' of Duoing than the 2nd continuous paper group W10, for the continuous paper of a distances roller surface side far away, equitant continuous paper became liner; The effect of extruding air layer weakens; So when being involved in more air, residual between the several successive paper of the continuous paper middle distance conveying roller R2 surface of a contact large-diameter portion X side far away have an air layer, in the large-diameter portion X of conveying roller R2; Contact between the continuous paper of the side that distances roller R2 surface is far away is insufficient, and the transmission of the power of the direct of travel that causes being formed by the friction force between the continuous paper is insufficient.
But; Residual the 2nd continuous paper group W10 ' that air layer is arranged between the continuous paper of a distances roller R2 surface side far away; Make the side face of the continuous paper contact of a distances roller R2 surface side far away near the conveying roller R3 of the downstream configuration of conveying roller R2; So to the continuous paper of this side the power of direct of travel is provided also from conveying roller R3, can suitable tension force be provided to whole the 2nd continuous paper group W10 '.
In addition, explanation replaces the conveying roller R3 of the feedway R of explanation in the above-described embodiment below, and is identical with conveying roller R1 and R2 on the conveying roller side face, the adjacent effect (with reference to Fig. 4) that the conveying roller R3 ' of large-diameter portion X and minor diameter part Y is set.
As stated; Residual the 2nd continuous paper group W10 ' that air layer is arranged between the several successive paper of a distances roller R2 surface side far away makes the side face of the continuous paper contact of a distances roller R2 surface side far away near the conveying roller R3 ' of the downstream configuration of conveying roller R2.On the side face of conveying roller R3 '; Identical with conveying roller R1 and R2, so adjacent large-diameter portion X and the minor diameter part Y of being provided with is in the scope of the large-diameter portion X of the contact conveying roller R3 ' of said the 2nd continuous paper group W3 ' scope with respect to contact minor diameter part Y; Can be powerful by being pressed on the conveying roller surface; On the other hand, in the scope of contact minor diameter part Y, the power of pushing the conveying roller surface is weak on the contrary; Residual air layer between the several successive paper of the side that the distances roller R2 surface of said the 2nd continuous paper group W10 ' is far away; Powerful from quilt by between the continuous paper that is pressed in the lip-deep contact large-diameter portion of conveying roller R3 ' X, be expressed in the scope of the weak minor diameter part Y of contact pressing force the said residual air layer disappearance between the continuous paper of contact large-diameter portion X.Therefore; In the large-diameter portion X of conveying roller R3 '; Each continuous paper that constitutes the 2nd continuous paper group W10 ' contacts each other, the transmission of the power of the direct of travel that the several successive paper of the side that distances roller R2 surface is far away also can carry out being formed by friction force more reliably.Therefore, can suitable tension force be provided to the whole continuous papers that constitute the 2nd continuous paper group W10 '.
; For these reasons, the configuration relation of conveying roller R2 and R3 (R3 '), promptly; Make two driven conveying rollers closer to each other; And with the configuration that a side of the 2nd continuous paper group surface and the opposing party surface keep batching the conveying roller that the angle contacts respectively, be provided with under a limited number of situation at position at it, preferably as this embodiment, be configured in roller be provided with that the interval is bigger, in the conveying roller portion in the downstream that is in the position that is involved in more air between the continuous paper easily.
On the other hand, to the 2nd continuous paper group W10 (W10 ') when tension force is provided,, then move and produce deflection to Width if can not obtain the balance of the tension force of advancing at the Width of the 2nd continuous paper group W10 (W10 ').Be located at the large-diameter portion of the side face of conveying roller R1, R2 and R3 '; Be configured near 4 positions the both ends that comprise the 2nd continuous paper group W10 (W10 '), so can near the Width both ends of the 2nd continuous paper group W10 (W10 '), carry out the transmission of the power of identical direct of travel.Therefore, the balance of the tension force that can on Width, keep advancing can not produce deflection.
According to the effect of above narration, can prevent in traveling process, to result from paper path in the feedway the 2nd continuous paper group W10 (W10 ') deflection and crawl.
In addition, be located at the large-diameter portion X of conveying roller R1, R2 and R3 ' and the differential 1mm of being about of minor diameter part Y, so can not go up residual broken line vestige at the 2nd continuous paper group W10 (W10 ') because of differential formation.
This embodiment uses spherical folding set square to form the 2nd continuous paper group, but the formation means of the 2nd continuous paper group are not limited thereto.
And the position that is provided with of the number of configured of the large-diameter portion of conveying roller and conveying roller is not limited to this embodiment, can in not breaking away from the claim scope, change.
