[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a folding introduction section with a forma sewing machine of a folding machine, and can be used for a folding machine for folding printed paper in an offset rotary printing machine.

[0002]

[Background technology]

 Conventionally, in offset rotary presses, etc., continuous paper (web) is continuously sent to the printing part for high-speed printing, and the printed paper that is continuously sent out is cut and folded as appropriate. A folding machine is installed on the downstream side.

In this folding machine, a work for folding the printed running paper in two in the vertical direction is appropriately performed, and a triangular plate-shaped former is used for the vertical folding work. Further, in order to smoothly perform the vertical folding by the former, it is necessary to previously make a perforation at the fold portion, and a forma-machine device is used for this perforation processing.

FIG. 3 shows a main part of a folding introduction section 90 with a former sewing machine device of a conventional folding machine. In the figure, a running paper 91 fed horizontally from the front side of the drawing is bent downward by a drag roller 92 extending in the width direction and fed to a former device 93. The former device 93 is composed of an isosceles triangular shaped frame 94 arranged below the drag roller 92 and a pair of guide rollers 95 arranged at the lower end thereof.

The former 94 is arranged so that the lower side, which is narrower, approaches the running portion of the running paper 91, that is, the lower side approaches the front side in the drawing, and the running paper 91 from the drag roller 92 is First, it proceeds along the former 94, and both side edges protruding from the inclined edge of the former 94 are folded back toward the back of the drawing in order to be folded in two by being sandwiched by the guide roller 95 at the lowermost end of the former 94. It is sent to a nipping roller (not shown) below to make sure creases.

Here, in order to make it possible to stably perform the folding with the nipping roller described above, the running paper 91 is subjected to the forming perforation by the forming machine 96 to guide the folding. The forma sewing machine device 96 has a sewing machine blade 97 that rolls while sandwiching the running paper 91 against the drag roller 92, and the running paper 91 sandwiched between the drag roller 92 by the sewing machine blade 97 extends vertically. The perforations 99 are formed. The machine blade 97 is supported by a bracket 98 that is moved along the drag roller 92 by a motor or the like, and can be rolled at any position of the drag roller 92. It is set to match the weighted position.

[0007]

[Problems to be solved by the device]

 By the way, in the folding introduction section 90 with the form sewing machine of the folding machine described above, the fold position to be formed on the running paper 91 changes variously according to the setting of the width dimension and the width direction position of the running paper 91. . Further, even during the printing operation, it may be necessary to correct the fold position due to the displacement of the running paper 91 or the like. In such a case, it is necessary to appropriately adjust the crease position of the former device 93 and the formation position of the perforation 99 of the former sewing device 96.

However, in these adjustments, the position adjustment of the former device 93 and the position adjustment of the form sewing machine device 96 had to be performed separately. In particular, since the perforations 99 must match the crease positions of the former device 93, the position of the former perforation device 96 must be adjusted after the position of the former device 93 has been adjusted. Specifically, first, the former device 93 is moved in the width direction of the running paper 91 so that the tip of the former 94 is aligned with a predetermined folding position, and then the bracket 98 of the former sewing machine device 96 is moved by a motor or the like. The work in which the perforation 99 by the perforation blade 97 was made to coincide with the folding position of the former device 93 was performed.

For these reasons, in the conventional folding machine with the form sewing machine device, the folding introduction section 90 has a problem that the work of adjusting the folding position is complicated and takes a lot of time. There was a problem that a lot of waste paper was generated when adjusting during printing.

An object of the present invention is to provide a folding introduction section with a forming sewing machine device of a folding machine, which allows quick and easy adjustment of the folding position.

[0011]

[Means for Solving the Problems]

 The present invention has a former for vertically folding a running paper sent from a printing portion of a rotary printing machine, and a former sewing machine for forming perforations at a fold portion of the running paper before being vertically folded by the former. However, it is characterized in that the former and the former sewing machine device can be integrally moved in the width direction of the running paper. The former sewing machine device includes a bracket supported by a former frame that supports the former, a guide roller that is supported by the bracket and is rotatable about a rotation axis extending in the width direction of the traveling paper, and the bracket. And a sewing machine blade supported by the guide roller and capable of rolling on the guide roller with the running paper sandwiched therebetween.

[0012]

[Work]

 In the present invention as described above, the perforation position by the forma sewing machine and the crease position by the former are aligned, and the perforation portion is used as a fold for vertical folding. If there is a change in the fold position of the running paper, move the former and adjust the crease position to match the new fold position. By this adjustment, the former sewing machine device also moves integrally with the former, and the perforation position is automatically adjusted so as to match the folding position of the running paper.

Therefore, if the position of the former is adjusted, the position of the former sewing machine is automatically adjusted, and the position adjustment of the former sewing machine can be omitted. That is, it is not necessary to adjust the positions of the former and the former sewing machine separately, as in the conventional case, and the fold position can be adjusted quickly and easily.

Further, if the sewing machine blade and the guide roller are supported by the frame of the former, the former and the former sewing machine device are mechanically integrated, and the adjustment described above is facilitated by a simple structure. Can be speeded up. Even if the guide roller is provided with a groove for receiving the perforation blade in order to ensure perforation processing, the guide roller moves integrally with the perforation blade, so the guide roller must be adjusted when the folding position is changed. Is unnecessary, and adjustment work can be done quickly and easily.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a folding introduction section 10 with a form sewing machine device of a folding machine according to the present invention. The folding introduction section 10 is provided in the front stage of the folding machine attached to the offset rotary printing press, and is fed from the printing portion of the offset rotary press (not shown, the front side of the drawing of FIG. 1, the left side of FIG. 2). The printed web 20 is separated at the center into two ribbons 21 and 22, and these ribbons 21 and 22 are vertically folded at the center to form bi-fold ribbons 23 and 24, respectively.

To this end, the fold-in section 10 is provided with a drag roller 12 on which a slitter 11 for separating the web 20 rolls, and two ribbons 21 and 22 from the drag roller 12 separated by the slitter 11 are longitudinally provided, respectively. Forming machines 31 and 32 for folding are provided, and forma sewing machines 41 and 42 for forming perforations 25 and 26 at the folds are also provided prior to each vertical folding. The ribbon 21 from the drag roller 12 is sent to the former device 31 via the compensating roller 13. Here, the series of webs 20, ribbons 21 and 22 and double-folded ribbons 23 and 24 are running papers in the folding introduction section 10.

Each of the former devices 31, 32 has a guide roller 35 that is cantilevered by a bracket 34 that is fixed to the outer side surfaces of the frame 33, and an isosceles triangular plate-like member that is inclined below the guide roller 35. The former 36 is provided with a pair of guide rollers 37 arranged at the lower end thereof. The frame 33 can be adjusted in position in the width direction of the ribbons 21 and 22 by being appropriately moved by a motor or the like. Further, the former devices 31 and 32 are arranged such that each frame 33 is shifted back and forth so as not to cause mutual contact interference and the like.

The brackets 34 are fixed to side surfaces of the frame 33 which are outside each other. The guide roller 35 is rotatably supported by the bracket 34 in a cantilevered state, and sends out the ribbons 21 and 22 sent in a substantially horizontal plane downward. The position where the guide rollers 35 are supported in the width direction of the ribbons 21 and 22 can be finely adjusted, and the total length is set to be sufficiently longer than the entire width of the ribbons 21 and 22. Even if the ribbon is moved to, the winding of the entire width of the ribbons 21 and 22 is maintained.

The former 36 is arranged so that the lower side, which becomes narrower, approaches the running portion of the downward ribbons 21, 22 from the guide roller 35 (that is, the lower side approaches the front side in the drawing). Therefore, the ribbons 21 and 22 from the guide roller 35 first advance along the former 36, and both side edges protruding from the inclined side edges of the former 36 are sequentially folded back toward the back side of the drawing, so that the uppermost portion of the former 36 is removed. It is folded in half at the lower end. The position of the fold that is folded in half is the position of the lower end side vertex of the former 36. The guide rollers 37 are arranged so as to face each other at a slight interval so as to sandwich the lower end of the former 36. Therefore, the folded ribbons 21, 22 fed from the lowermost end of the former 36 are sandwiched between the guide rollers 37 to be folded ribbons 23, 24, respectively. In order to facilitate the insertion of the ribbons 21 and 22, the guide rollers 37 can be moved in the directions toward and away from each other by driving a motor or the like.

Each of the former sewing machines 41 and 42 is provided with a sewing machine blade 43 which rolls around the guide rollers 35 of the formers 31 and 32 while sandwiching the ribbons 21 and 22, respectively. The sewing machine blade 43 is cantilevered by an arm 44 extending from the bracket 34 of the former device 31, 32, and the supporting portion can finely adjust the position of the ribbons 21, 22 in the width direction. The arm 44 is rotatably supported on the upper end of the bracket 34 by a motor drive or the like as appropriate, and the sewing machine blade 43 is separated from the guide roller 35 so that the ribbons 21 and 22 can be easily inserted.

Perforations 45 are formed around the perimeter of the perforation blade 43 at predetermined intervals, and perforations 25 and 26 can be formed on the rolling ribs 21 and 22. Here, the guide rollers 35 of the former devices 31 and 32 are formed with grooves 46 that extend over the entire circumference at predetermined positions, and the cutting edges 45 of the sewing machine blades 43 are inserted into the grooves 46 so that the perforations are formed. 25 and 26 can be formed smoothly and surely. By supporting the former 34 and 42 of the former sewing machine on the bracket 34, the former sewing machine 41 and 42 are integrated with the guide roller 35, the former 36, etc. along with the width adjustment of the ribbons 21 and 22 of the former 31 and 32. Can be moved.

In the present embodiment having such a configuration, the setting and adjustment of each unit is adjusted in advance at the time of installation or at the time of regular maintenance. That is, the former devices 31 and 32 are set at predetermined positions in the width direction of the ribbons 21 and 22, and in this state, the sewing machine blades 43 of the former sewing device 41 and 42 are appropriately moved in the width direction of the ribbons 21 and 22 to form the former device. Set it so that it matches the crease position of 31 and 32 (the lower end apex position of the former 36). Further, the guide rail 35 is appropriately moved in the width direction of the ribbons 21 and 22, and the groove 46 is set so as to coincide with the cutting edge 45 of the sewing machine blade 43.

After these setting adjustments are completed, the running paper is vertically folded according to the following procedure. That is, the leading end of the web 20 from the printed portion is passed through the slitter 11, and the ribbons 21 and 22 on the leading end side are wound around the guide rollers 35 via the drag rollers 12 and 13 and guided to the lower side, and the former 36 and the guide roller 37. Pull it downwards in the state of the folded ribbons 23, 24. When the printing press is operated in this state, the printed web 20 is cut off by the slitter 11, and the perforation machines 41 and 42 are machined with the perforations 25 and 26 in the state of the ribbons 21 and 22, respectively. The devices 31 and 32 are vertically folded at the perforations 25 and 26 to form two-fold ribbons 23 and 24. At this time, the positions of the perforations 25 and 26 formed by the respective former sewing machines 41 and 42 are preset so that the perforation blades 43 forming these are aligned with the crease positions of the former machines 31 and 32. In the former devices 31 and 32, the folds are surely placed at the perforations 25 and 26, and a good vertical folding state can be obtained.

On the other hand, when the paper width or fold position of the ribbons 21 and 22 is changed or deviated from the desired position, the former devices 31 and 32 are moved in the width direction of the ribbons 21 and 22. , Adjust the crease at the bottom edge of Form 36 to a new crease position or the original crease position. At this time, since the former sewing machines 41 and 42 and the formers 31 and 32 are integrally configured, each former 31 and 32 is moved so that the former 36 comes to the desired folding position. Then, the position of the sewing machine blade 43 of each of the former sewing machines 41 and 42 is automatically moved to the desired folding position. Further, since the guide roller 35 also moves integrally with the former devices 31 and 32, the groove 46 of the guide roller 35 is always maintained at a position corresponding to the sewing machine blade 43 of the former sewing machine devices 41 and 42. Therefore, even if the paper width or the fold position is changed, if the former devices 31 and 32 are adjusted, no other adjustment is necessary.

According to this embodiment, the following effects can be obtained. That is, by forming perforations 25 and 26 at the fold positions of the ribbons 21 and 22 with the forma sewing machines 41 and 42 and vertically folding them so that the folds come to the fold positions with the former machines 31 and 32. The crease position for vertical folding and the position of the perforations 25, 26 can be made to coincide with each other, and the perforations 25, 26 can be folded and the vertical folding can be performed easily and reliably in a stable state.

Since the former sewing machines 41 and 42 and the formers 31 and 32 are provided so as to be integrally moved in the width direction of the ribbons 21 and 22, the fold positions of the ribbons 21 and 22 are changed. Even in this case, the work associated with this change can be performed easily and quickly. That is, if the crease positions of the former devices 31 and 32 are adjusted, the formation positions of the perforations 25 and 26 of the form machine sewing devices 41 and 42 are automatically adjusted accordingly, so that the former sewing device 41 and 42 are formed. You can omit your own adjustments. Therefore, the former devices 31, 32 and the former sewing machine devices 41, 42 can be adjusted to the desired fold position by one adjustment, and the workability can be improved.

In particular, by supporting the former sewing machine devices 41 and 42 on the former devices 31 and 32 so that mechanical integration is performed, it is necessary to have a structure for linking separately operating devices. Without, the structure can be extremely simple. Further, since the guide roller 35 is also integrally moved with respect to the sewing machine blade 43 of the forma sewing machine devices 41, 42, even if the position of the sewing machine blade 43 is changed, the cutting edge 45 thereof is always in the groove 46 of the guide roller 35. Since the perforations 25 and 26 can be reliably formed, the mutual adjustment work for changing the position of the folds of the ribbons 21 and 22 can be omitted. Can be increased.

On the other hand, the sewing machine blades 43 of the former sewing machines 41, 42, the guide rollers 35, the formers 36, etc. of the former machines 31 can be individually fine-adjusted in the width direction positions of the ribbons 21, 22. It is possible to make fine adjustments so that the respective positions match during maintenance and inspection. Therefore, when the positions of the perforations 25 and 26 formed by the forma sewing machines 41 and 42 and the crease positions of the former machine 31 are set in advance, accurate setting can be performed and readjustment can be performed even if there is a secular change. This can be done easily and the positional accuracy can be secured by changing the fold position during the work described above.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and the following modifications and the like are also included in the present invention. That is, in the above-described embodiment, the mechanical sewing machines 41 and 42 are supported by the former machines 31 and 32 to perform mechanical integration, but the bracket 34 and the arm for realizing these integrated support are provided. The specific structure such as the form and support position of 44 is not limited to the form of the above-mentioned embodiment, and may be appropriately changed in the implementation.

Further, the mechanical sewing machine 41, 42 and the former machines 31, 32 are not limited to the mechanical integration by the support as in the above-described embodiment, and are separately movably installed in the width direction of the ribbons 21, 22. , May be connected by other link members or the like to achieve mechanical integration. Then, the former sewing machine devices 41, 42 and the former devices 31, 32 are separately movably installed in the width direction of the ribbons 21, 22, and a motor or the like for individually driving each is provided. The respective movements may be integrated by interlocking so that the respective positions coincide with each other.

Further, in the above-mentioned embodiment, the guide roller 35 is moved together with the former sewing machine device 41, but unless the cutting edge 45 of the sewing machine blade 43 is inserted into the groove 46, the guide roller 35 It is not necessary to move the 35 as a unit, and a fixed type may be used. However, by performing the sliding as in the above-described embodiment, the perforations 25 and 26 can be reliably formed, and the adjustment work accompanying the change of the fold position can be further simplified.

On the other hand, in the above-mentioned embodiment, the two former sewing machines 41, 42 with the former sewing machines 31, 32 are alternately arranged in the front-back direction (the left-right direction in FIG. 2), but these two machines interfere with each other due to mutual interference of members. If not present, they may be arranged side by side directly side by side, or the relative positional relationship may be selected by allowing position adjustment in the front-back direction. Further, although the ribbons 21 and 22 have different paths in the above embodiment, they may be guided substantially in parallel. However, when there are two forming devices 31, 32, etc. as in the above-described embodiment, it is necessary to avoid contact interference between the ribbons 21, 22 and the device portion, and the ribbon It is desirable to take measures such as changing the route of Routes 22 and 22.

In the above embodiment, the web 20 is divided into two ribbons 21 and 22, and the ribbons 21 and 22 are used as running papers, one former device 31 and one former device 41 and 42, respectively. Although the web 20 is used as the running paper, one former and one former sewing machine device may be used. Further, the form, arrangement, shape and size of the sewing machine blade 43 of the former sewing machine device 41, 42 and the cutting edge 45 thereof, the former 36 of the former device 31, 32, the guide roller 37, the guide roller 35 and the groove 46 thereof are arbitrary. Yes, you can refer to the existing ones and select them appropriately at the time of implementation.
