Description

  The present invention relates to a folding machine equipped in a printing machine and capable of folding two kinds of booklets, a printing machine including the folding machine, and a composite folding method.

For example, in the case of a newspaper for home delivery, it is common practice to insert advertisements (sub-booklets) such as advertisements into newspaper signatures (main booklet), but such operations are usually performed manually. .
On the other hand, Patent Document 1 describes a technique for automatically inserting another booklet into the booklet as described above.

When inserting a sub-booklet such as an advertisement into a main booklet such as a newspaper signature, the sub-booklet may have a different cut length (size) from the main booklet. Requires operating two or more different cut length printing machines to produce booklets of two or more sections of different sizes, and further, after printing each booklet, it is necessary to insert each booklet separately by an inserter. As described above, the technique of Patent Document 1 is equipped with two or more different-cut length printing machines and an inserter so that a booklet of a different size can be automatically folded into the booklet. .
JP 2007-131003 A

  However, for example, in the case of a newspaper rotary press, in order to cope with so-called double-out, single-out, transfer-out, etc., it is common that the cut length of each folding machine is set to be the same. It is not possible to operate two or more different cut length printing machines. Therefore, as in the technique of Patent Document 1, in order to prepare a different cut length printing machine, a significant increase in equipment is required, resulting in a large increase in equipment cost. In addition, an insert facility such as an inserter is required, and this also requires a significant facility cost.

  On the other hand, if printing of advertisements having a cut length different from that of newspapers, etc. is performed using an existing printing machine having a cut length corresponding to the printing, a new equipment cost is not increased for the printing machine. However, since the printing presses with different cut lengths are not usually lined up in a newspaper press, a separate booklet such as an advertisement is printed separately from the main booklet such as a newspaper to make it into a booklet. It will be inserted into the main booklet.

  Therefore, an insert facility is indispensable, and an increase in facility cost in this respect is inevitable. In addition, it is not easy to print a sub-booklet at the same time as the main booklet is printed, and it takes time to print the sub-booklet and time to transport it, and more time is required to insert the booklet.

A second paper discharge device arranged, a first transport route for guiding the printed second web group to the first cutting device, and the second web group as the second sheet. And a second transport route that leads to the cutting lateral folding device.

  The composite folding method of the present invention is printed when the first web group consisting of one or a plurality of printed webs is cut to a first cutting length and folded horizontally to form a first booklet. A second web group consisting of one or a plurality of webs is folded into a state in which a second booklet formed by cutting and transversely folding to a second cutting length equal to or shorter than the first cutting length is inserted. In the composite folding method, the first step of cutting the second web group into the second sheet group having the second cutting length in advance, and the cutting the second sheet group, A second step of guiding the first web group to a folding cylinder for cutting the web group, and when the first web group is wound around the folding cylinder, the second sheet group is placed on the outer periphery of the folding cylinder and the first A third step of inserting between the first web group and the second web group on the outer periphery of the folding cylinder. A fourth step of holding the sheet group and rotating together with the folding cylinder to cut the first web group into the first sheet group of the first cutting length by the cutting cylinder; And a fifth step of simultaneously folding the first sheet group and the second sheet group of the first sheet group and the second sheet group from the folding cylinder to a folding roller (claim 15). .

  According to the composite folding machine of the present invention (Claim 1), the second web group is cut in advance by a cutting device, and the cut second sheet group is guided by the guide mechanism, and the cutting horizontal folding device Is fed between the first web group fed to the outer periphery of the folding cylinder and the outer periphery of the folding cylinder and wound around the outer periphery of the folding cylinder together with the first web group. Then, after the first web group is cut by the first cutting cylinder of the cutting horizontal folding device, the cut first sheet group and second sheet group are simultaneously folded horizontally by the folding roller. As a result, a booklet (main booklet) in which the first sheet group is horizontally folded is simultaneously formed in a state in which a booklet (secondary booklet) in which the second sheet group is horizontally folded is inserted. Therefore, if the cutting length of the second sheet group is made shorter than the cutting length of the first sheet group (Claim 2), it is possible to automatically fold a booklet of a different size into one booklet. Become.

  The cutting device is configured so that the cutting length of the second sheet group can be adjusted, and the conveying device is transported to the cutting horizontal folding device by changing the speed of the second sheet group to a speed corresponding to the cutting length. If it is configured, sub-booklets of various sizes (booklets in which the second sheet group is horizontally folded) are inserted into the main booklet (booklet in which the first sheet group is horizontally folded) (Claim 3).

  If the conveying device is a conveying belt device having a pair of conveying belts facing each other, the second sheet group is conveyed while the second sheet group is sandwiched between the pair of conveying belts, and therefore the second sheet group is conveyed in a predetermined posture. It is easy to feed stably between the first web group and the outer periphery of the folding cylinder. It is also easy to change the speed of the second sheet group to a speed corresponding to the cutting length while being conveyed.

  Further, if the guide mechanism includes a holding mechanism that holds the second sheet group on the outer periphery of the folding cylinder, the guide sheet is held in a proper posture while holding the second sheet group at a predetermined position with respect to the first sheet group. The second sheet group itself can be folded horizontally at an appropriate position, and the auxiliary booklet made up of the second sheet group can be formed into an appropriate shape. It can be formed (Claim 5).

  In this case, if the holding mechanism has a mechanism for gripping the second sheet group with the claws, the second sheet group can be held without making a hole or the like (Claim 6). However, if there is a mechanism for inserting and holding the needle into the second sheet group, the second sheet group can be held with a simple structure although a hole is opened in the second sheet group. Further, if the needle inserted into the second sheet group is also used as a needle for holding the first sheet group on the outer periphery of the folding cylinder, the apparatus configuration is simplified and the apparatus cost can be reduced. .

Further, if the holding mechanism has a nip roller that presses the second sheet group against the outer periphery of the folding cylinder, the second sheet group is difficult to lift from the outer periphery of the folding cylinder, and the second sheet group is moved to the first web. It can be reliably fed between the group and the outer periphery of the folding cylinder (claim 9).
If such a nip roller is provided together with the needle, the second sheet group is lifted from the outer periphery of the folding cylinder by inserting the needle while securely holding the second sheet group on the outer periphery of the folding cylinder by inserting the needle. Therefore, the second sheet group can be fed into the proper arrangement between the first web group and the outer periphery of the folding cylinder and reliably sent (claim 10).

Further, if the holding mechanism has a suction portion inside the folding cylinder outer peripheral surface and has a suction mechanism for sucking and holding the second sheet group outer peripheral surface, the second sheet group is damaged. Can be held on the outer periphery of the folding cylinder (claim 11).
Further, if the conveyor device is a conveyor belt device and the guide mechanism has a roller that is provided facing the conveyor belt facing the outer periphery of the folding cylinder and can rotate in synchronization with the conveyor belt, the conveyor belt and the roller The second sheet group can be surely fed between the first web group and the outer periphery of the folding cylinder while the second sheet group is sandwiched between the roller and the roller. If they are arranged close to each other, the second sheet group can be guided more appropriately. In particular, when this roller is applied, since the second sheet group is not restrained until the second sheet group enters between the first web group and the outer periphery of the folding cylinder, if the suction mechanism is further applied, The second sheet group can be reliably held on the outer peripheral surface of the folding cylinder until it reaches the outer periphery of the folding cylinder from the roller and enters between the first web group and the outer periphery of the folding cylinder.

In addition, if the guide mechanism has a phase adjustment mechanism that adjusts the phase of the second sheet group with respect to the first web group and feeds the second sheet group between the first web group and the outer periphery of the folding cylinder, the second sheet The sheet group can be arranged at a desired position with respect to the first web group and can be folded horizontally at the desired position.
According to the printing machine (Claim 14) provided with the composite folding machine of the present invention, if the first transport route is used, the second sheet group cut in advance by the cutting apparatus is overlapped on the first web group. The first web group and the first sheet group and the second sheet group that have been trimmed at the same time by the first trimming lateral folding device are simultaneously laterally folded to form a booklet (main booklet). ), A booklet (sub-booklet) of the second sheet group is inserted into the first sheet discharge device (so-called “single-out”).

Further, if the second transport route is used, a booklet composed of the first sheet group formed by cutting the first sheet group by the first cutting horizontal folding device and laterally folding the first sheet group from the first paper discharge device. On the other hand, a booklet composed of the second sheet group formed by cutting the second sheet group by the second cutting horizontal folding device and then laterally folding the paper is discharged from the second paper discharge device (so-called double feeding). )be able to.
Therefore, a highly versatile printing machine is configured.

  According to the composite folding method (Claim 15) of the present invention, when the first web group is wound around the folding cylinder, the second sheet group is inserted between the outer periphery of the folding cylinder and the first web group. After cutting the first web group, the superposed first sheet group and second sheet group are sent from the folding cylinder to the folding roller and simultaneously folded horizontally. As a result, a booklet (main booklet) in which the first sheet group is horizontally folded is simultaneously formed in a state in which a booklet (secondary booklet) in which the second sheet group is horizontally folded is inserted. In other words, if the cutting length of the second sheet group is made shorter than the cutting length of the first sheet group, it is possible to automatically fold a booklet of a different size into one booklet.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Each of the web groups 1 and 2 is usually configured by collecting a plurality of webs through a web path portion, but the present invention itself may be a single web. In the formers 10 and 20, the web groups 1 and 2 are vertically folded. When the formers 10 and 20 are cut in the longitudinal direction by a slitter immediately before the formers 10 and 20, the webs fed downstream from the formers 10 and 20. The group is not a vertically folded group, but becomes a web group having an opposite width obtained by superimposing the number of sheets by double cutting. Here, it is assumed that the second former 20 is configured to be capable of cutting in the vertical direction using such a slitter. Note that the formers 10 and 20 provided in the present embodiment are not indispensable as a printing machine according to the present invention. For example, when vertical folding is unnecessary, the former is configured by a simple path changing roller or the like. There is also.

  A first cutting cylinder 13, a folding cylinder 12, and a folding roller 14 are provided downstream of the first former 10, and the first web 1 fed from the first former 10 via the nip roller 10 a is provided. A cutting horizontal folding device (first cutting horizontal folding device) 11 that cuts and folds horizontally is provided.

  Then, the second sheet group (also abbreviated as the second sheet) 2A formed by cutting the second web 2 by the cutting device 21 is conveyed from the cutting device 21 to the cutting horizontal folding device 11 to the cutting horizontal folding device. As the conveying device, a conveying belt device 24 having a pair of conveying belts arranged opposite to each other and conveying the second sheet 2A is provided. Thus, the first web 2 is cut by the cutting device 21, sent to the cutting lateral folding device 11 via the transport belt device 24, and overlapped with the first web 1 to be folded. Composed.

On the other hand, in the case of this embodiment, another cutting horizontal folding device (second cutting horizontal folding device) 11A is provided below the cutting device 21, and the second web 2 is cut through the guide roll 20b. The apparatus 21 is detoured and sent to the cutting horizontal folding apparatus 11A, and can be cut and folded horizontally to form a signature (booklet) 2B irrespective of the first web 1 system.
Further, on the downstream side of the cutting horizontal folding device 11 and the downstream side of the cutting horizontal folding device 11A, the impellers 15 and 28 and the paper discharge conveyor as paper discharge devices for discharging the formed signatures (booklets) 1B and 2B, respectively. 16, 29 and 30 are provided.

<Main components of the compound folding machine>
Here, the main part of this compound folding machine will be described.
As shown in FIG. 2A, the second sheet 2 </ b> A cut by the cutting device 21 is nipped between the pair of conveying belts 24 a and 24 b of the conveying belt device 24 and conveyed to the cutting horizontal folding device 11. The conveying belts 24a and 24b are arranged so as to reach the vicinity of the outer peripheral surface of the folding cylinder 12 of the cutting lateral folding device 11 by the guide roll 24c, and the second sheet 2A has a sufficient length at the rear thereof. And reaches the outer peripheral surface of the folding cylinder 12 while being sandwiched between the conveyor belts 24a and 24b.

  The folding cylinder 12 includes a needle 12b that enters the first web 1 and holds the first web 1 on the outer peripheral surface of the folding cylinder 12, and a first sheet 1A that is cut from the first web 1. And a folding blade 12 a for feeding the second sheet 2 </ b> A to the folding roll 14. The cutting cylinder 13 facing the folding cylinder 12 is provided with a saw blade 13a at a position corresponding to the phase of the folding blade 12a and the needle 12b of the folding cylinder 12.

  Here, the second sheet 2A is fed between the first web 1 fed to the outer periphery of the folding cylinder 12 and the outer periphery of the folding cylinder 12 so as to be wound around the outer periphery of the folding cylinder 12 together with the first web 1. As a guide mechanism for guiding, a holding mechanism for holding the second sheet 2A on the outer periphery of the folding cylinder 12 is provided. This holding mechanism is a claw device (hereinafter simply referred to as a claw) 31 provided on the outer peripheral surface of the folding cylinder 12, and the claw 31 holds the front end of the second sheet 2 </ b> A on the outer circumference of the folding cylinder 12. It is like that.

  As a more specific configuration of the claw 31, as shown in FIG. 2 (b), the claw 31 is mounted on the inner side of the outer peripheral surface of the folding cylinder 12, and is pivotally supported by the pin 31b to be close to the outer peripheral surface of the folding cylinder 12. And a receiving surface 31d formed inside the outer peripheral surface of the folding cylinder 12 with which the claw portion 31c at the tip of the swinging claw 31a abuts. it can. Thereby, the front end of the second sheet 2A can be held by the claw portion 31c and the receiving surface 31d of the swinging claw 31a, and the second sheet 2A can be held on the outer periphery of the folding cylinder 12. In this case, since the swinging claw 31a does not protrude from the outer peripheral surface of the folding cylinder 12, there is no problem even when the first sheet 1A is held on the outer periphery of the folding cylinder 12 for processing.

  Alternatively, as shown in FIG. 2 (c), the claw 13 is more specifically configured so as to be installed inside the outer peripheral surface of the folding cylinder 12 and pivotally supported by the pin 31 b ′. A swinging claw 31a ′ that swings in the circumferential direction near the front end side, and a receiving surface 31d ′ that is formed inside the outer peripheral surface of the folding cylinder 12 with which the claw portion 31c ′ at the tip of the swinging claw 31a ′ abuts, A configuration including an insertion member 31e for inserting the front end of the second sheet 2A toward the receiving surface 31d ′ can be used. In this case, in FIG. 2B, the receiving surface 31d is configured to be substantially parallel to the outer peripheral surface of the folding cylinder 12, but in FIG. 2C, the receiving surface 31d 'is the outer peripheral surface of the folding cylinder 12. The front end of the second sheet 2A needs to be inserted into the receiving surface 31d 'by the insertion member 31e. However, the receiving surface 31d' and the claw portion 31c are substantially perpendicular to the outer peripheral surface of the folding cylinder 12. By gripping with ', the second sheet 2A can be more reliably held on the outer periphery of the folding cylinder 12.

The swinging claws 31a and 31a 'swing at an appropriate timing, and the insertion member 31e moves toward the center of the folding cylinder 12 at a predetermined timing to receive the front end of the second sheet 2A. As soon as it is inserted into the surface 31 d ′, it retracts outward from the outer peripheral surface of the folding cylinder 12 so as not to interfere with the rotating folding cylinder 12.
As shown in FIG. 3A, the holding mechanism includes a needle 32 that moves in and out of the outer peripheral surface of the folding cylinder 12 and enters and holds the front end of the second sheet 2A, and the front end is held by the needle 32. A nip roller 33 that presses the held second sheet 2 </ b> A to the outer periphery of the folding cylinder 12 can also be configured. In this case, the needle 32 protrudes and enters the front end of the second sheet 2A to hold the second sheet 2A, and then the nip roller 33 grips the second sheet 2A between the outer peripheral surface of the folding cylinder 12 and the second sheet 2A. In the stage, the folding cylinder 12 is dipped inward from the outer peripheral surface.

In the case of such a holding mechanism, the needle 32 holds the front end of the second sheet 2A, and the nip roller 33 then folds the first sheet 1 without the second sheet 2A floating from the outer periphery of the folding cylinder 12. It is guided so as to be surely fed between the outer periphery of the trunk 12 and the roles are divided.
However, if the rigidity of the second sheet 2A is high due to, for example, a large number of sheets, the second sheet 2A can be securely placed between the first web 1 and the outer periphery of the folding cylinder 12 even if the nip roller 33 is omitted. Can be sent to.

Further, the length of the second sheet 2A (that is, the cut-off length of the second web 2) is close to the length of the first sheet 1A (that is, the cut-off length of the first web 1) or If they are equal, the second sheet 2 </ b> A may be held on the outer periphery of the folding cylinder 12 using a needle 12 b that holds the first web 1 on the outer peripheral surface of the folding cylinder 12 (also used as a combination).
Further, as shown in FIG. 4, the guide mechanism is arranged close to the outer periphery of the folding cylinder 12 with a clearance and can be rotated so as to face one of the conveying belts 24a facing the outer periphery of the folding cylinder 12 of the conveying belt device 24. A roller 34 is provided, the roller 34 is rotated in synchronization with the conveying belt 24a, and the second web 2A is sandwiched between the conveying belt 24a and the roller 34 while the first web 1 and the outer periphery of the folding cylinder 12 are You may make it send in between.

However, in this case, since the second sheet 2A is not restrained until it enters between the first web 1 and the outer periphery of the folding cylinder 12 from the location guided by the roller 34, as shown in FIG. It is conceivable to further add a suction mechanism 35 that sucks and holds the leading end of the second sheet 2A. The suction mechanism 35 may be configured by a vacuum box 35a disposed at a required position facing the outer periphery of the folding cylinder 12 and a vacuuming device (not shown) that evacuates the vacuum box 35a.
Further, even if the suction mechanism 35 is used alone, the tip of the second sheet 2A can be sucked and held on the outer periphery of the folding cylinder 12.

<Change of conveyance speed>
By the way, in this embodiment, the printing system of the 2nd web 2 is comprised as a variable cut-off machine which can adjust cut-off length. Therefore, the length of the second sheet 2A (that is, the cutoff length of the second web 2) is shorter than the length of the first sheet 1A (that is, the cutoff length of the first web 1). In this case, the conveyance speed of the second web 2 from the printing unit (not shown) to the second former 20 and the cutting device 21 is slower than the conveyance speed of the first web 1. In the cutting horizontal folding device 11, it is necessary to increase the conveyance speed of the second sheet 2A so that one part of the second sheet 2A corresponds to one part of the first sheet 1A. The conveyor belts 24a and 24b of the conveyor belt device 24 also receive the second sheet 2A from the cutting device 21 and then feed the second sheet 2A to the cutting lateral folding device 11 by accelerating the conveying speed. The configuration shown in FIG. 6 is preferable.

As shown in FIG. 6, an upstream conveyor belt device 241 and a downstream conveyor belt device 242 are provided as the conveyor belt devices.
The upstream conveyance belt device 241 includes a pair of opposed conveyance belts 241a and 241b, and guide rollers 241c to 241h for guiding the conveyance belts 241a and 241b to a predetermined path, and the second sheet 2A is a second sheet 2A. The former 20 and the cutting device 21 are conveyed at the same speed.

  The downstream conveyance belt device 242 includes a pair of opposed conveyance belts 242a and 242b, and guide rollers 242c, 242e, and 242g to 242j for guiding the conveyance belts 242a and 242b to a predetermined path. The sheet 2A is accelerated at a higher speed than the upstream conveyance belt device 241 and fed into the folding cylinder 12. Here, 242f is a driving roller (transmission roller), and this driving roller 242f can change the rotation speed so that the conveyor belts 242a and 242b can be accelerated and decelerated.

Further, the guide rollers 242c and 242d arranged opposite to each other at the entrance of the downstream conveyance belt device 242 are separated from each other according to the rotational speed of the transmission roller 242f, as shown by the solid line in FIG. As shown by a two-dot chain line, the sheet is switched to a close sheet holding position.
That is, when the second sheet 2A is conveyed at a speed higher than the speed of the second web 2 by the downstream conveyance belt device 242, the guide rollers 242c and 242d are set to the sheet opening position, and the downstream conveyance belt device 242 When the sheet 2A is being conveyed at a speed equal to the speed of the web 2, the guide rollers 242c and 242d are in the sheet clamping position. Accordingly, it is possible to prevent a speed difference from occurring when the sheet 2A is transferred from the upstream conveyance belt device 241 to the downstream conveyance belt device 242, and the sheet 2A can be smoothly transferred without any problem. ing.
Note that the holding position of the mechanism for holding the sheet 2A, such as the claw 31 or the needle 32, is variable according to the cut-off length.

<Action, effect>
Since the composite folding machine according to the first embodiment of the present invention is configured as described above, the composite folding can be performed as follows.

That is, the second web 2 </ b> A is cut in advance by the cutting device 21, the cut second sheet 2 </ b> A is guided by the guide mechanism, and is fed to the outer periphery of the folding cylinder 12 of the cutting lateral folding device 11.
Then, by feeding the second web 2A between the first web 1 and the outer periphery of the folding cylinder 12 before cutting and before the cutting cylinder 12, the second web 2A is fed to the first web 1A. The web 1 is wound around the outer periphery of the folding cylinder.

Thereafter, after the first web 1 is cut by the cutting cylinder 13 of the cutting and folding device 11, the cut first sheet 1A and the second sheet 2A are folded using the folding blade 12a.
