Description

[0001]
[Industrial application fields]
The present invention relates to a paper folding apparatus in which a plurality of paper folding portions are disposed in a machine body, and a plurality of folding rollers and folding plate members fold a plurality of long belt-like sheets.
[0002]
[Prior art]
As a paper folding device that can automatically fold a long belt-like sheet such as a letter, a letter of thanks, and a memorandum into a state of being folded many times, Japanese Patent Application No. 6-6 There are those described in 268916. This paper folding apparatus has a plurality of folding plate members, stoppers and a plurality of folding rollers as sheet folding means, and these are arranged in an appropriate number for the purpose of paper folding. This corresponds to the number of paper folds. When a sheet having a length shorter than the length of the long belt-like sheet is folded, the sheet is usually folded by changing the number of paper folding. That is, folding is performed with the number of foldings reduced. In order to reduce the number of folds, the conventional paper folding apparatus removes as many folding plate members as the number to be reduced from the arrangement position, and changes the paper discharge position to change the position of the paper receiving member. Moreover, when returning the number of folds to the original, the folded plate member previously removed was mounted again.
[0003]
Japanese Laid-Open Utility Model Publication No. 52-66222 discloses a paper folding apparatus capable of coping with a decrease in the number of folding accompanying a change in the number of folding. This conventional paper folding apparatus is provided with a plurality of multi-stage folding rollers, a folding plate member and a stopper, and a feed that opens and closes the entrance of the paper folding member at the tip of the folding plate member by the rotation of a pivot. In the case of normal paper folding, the guide plate body is connected, and the pivotal support of the folded plate member is expanded rearward around the fulcrum, and the feed guide plate body is expanded rearward to be the folded plate member. If it is placed on the entrance, the entrance of the folded plate member is released in a normal state, and the sheet is subjected to normal normal paper folding operation by adjusting the movement of the stopper to a predetermined position. The paper is folded according to the number.
[0004]
Next, when the number of folds is changed to be smaller than necessary, the number of folded plate members corresponding to the number of folds is left, and the other unnecessary number of folded plate member groups slightly backs the equipment position, When the pivotal support of the folded plate member is spread forward, the entrance of the folded plate member is shielded by the feed guide plate body, and the sheet is guided along it and passes without folding. On the other hand, the folding plate member having an open entrance can normally fold paper normally and obtain the required number and change the reduced number of folding.
[0005]
[Problems to be solved by the invention]
However, the paper folding apparatus described in Japanese Patent Application No. 6-268916 has a number of problems. That is, when the number of folds is changed, for example, when the number of folds is decreased, it is necessary to remove the number of the fold plate members from the position where the folded plate member is disposed and change the paper discharge position to change the position of the paper receiving member. Moreover, when returning the number of folds, the folded plate member previously removed had to be mounted again.
[0006]
In order to adapt to the number of folds, it has been proposed to replace and arrange the folding path member separately instead of the folding plate member. However, the arrangement of the folding path member is not limited to the replacement installation with the folding plate member. Therefore, these replacement operations are not easy and extremely inconvenient because the folded plate member is very heavy. In order to solve this, a folding path member controlled by a solenoid or the like is arranged in the vicinity of the folding roller side of the folding plate member, and the insertion of the sheet into the folding plate member is prevented or allowed by this folding path member. However, this structure is very complicated and expensive, the entire paper folding apparatus is enlarged, and it is difficult to arrange all the folding plate members. Since the positional relationship has to be adjusted for each, the adjustment work is extremely complicated.
[0007]
In addition, there is a structure in which the stopper is also used as a folding path member, but this must move the position of the stopper each time, so that the predetermined position that has been aligned is deviated. When the paper folding is performed, since the stopper is provided for each folding plate member, the adjustment work is extremely complicated.
[0008]
Also, in the other conventional paper folding apparatus disclosed in Japanese Utility Model Publication No. 52-66222, when the number of folding is reduced due to the change in the number of folding, the number of folding plate members to be reduced is arranged from the arrangement position. It was necessary to move and spread the feed guide plate forward. Also, when returning the number of folds to the original, it is necessary to expand the feed guide plate body that has been expanded first, and then move the folding plate member again, and the folding plate members overlap each other in many steps. Therefore, it is extremely difficult to spread the feed guide plate body of the folded plate member except for the uppermost stage in these operations.
[0009]
Moreover, in the conventional multi-stage paper folding apparatus, when the number of folding is increased, as many feed guide plate bodies as that are required, and it is necessary to provide a mechanism for moving and fixing each folding plate member from the arrangement position. However, there is a problem that the apparatus becomes complicated and expensive.
[0010]
In order to easily spread the feeding guide plate body of the folding plate member with a conventional paper folding device, if the gap between the folding plate members is widened, the outer diameter of the folding roller inevitably increases. However, there is a problem that the apparatus becomes large and expensive.
[0011]
The present invention has been made in view of such a problem, and can easily change the number of folds, avoid an increase in the size of the device, and reduce the manufacturing cost as a desktop device. An object is to provide a paper folding device.
[0012]
[Means for Solving the Problems]
A paper folding device according to the present invention is a pair of plate members into which a leading end of a sheet enters in a paper folding device that takes out sheets one by one from a sheet bundle placed on a paper feeding plate and folds them into a predetermined folding shape. A stopper that locks the leading edge of the sheet between the plate members, and a roller group that feeds the sheet between the plate members and folds the bent sheet with the leading end locked to the stopper. A plurality of paper folding portions, a folding plate mounting plate for fixing and supporting the plurality of paper folding portions, a fulcrum shaft for swingably supporting the folding plate mounting plate, and the plurality of paper folding portions.

[0036]
As shown in FIG. 5, reference numeral 70 denotes a folding path member. The folding path member 70 has a regulation plate 72 fixed to a base portion 71 a of a guide plate 71 that is bent in a substantially L shape. Fixed on 72 is a magnet plate 73 configured by sandwiching and fixing a pair of magnets 74 positioned in the width direction of the sheet up and down by magnetic flux plates 75. A magnet catcher or the like may be used instead of the magnet plate 73.
[0037]
The folding path member 70 includes the guide plate 32 and the folding plate 33 of the folding plate member 31 until the regulating plate 72 abuts the leading end side 71b of the base 71a of the guide plate 71 with the leading end side of the folding plate 33 on the folding roller side. The tip sides 75a of the upper and lower magnetic flux plates 75 of the magnet plate 73 are fixed by being magnetically attached to the bent portion of the guide member 32 on the folding roller side.
[0038]
As shown in FIG. 3, the folding path member 70 is configured such that a sheet folded through the folding roller 16 and the press roller 15 is guided by a bending portion 71c of the guide plate 71, so that the third folding plate member 31c Proceeding to the space surrounded by the guide plate 32c and the folding plate 33c is guided to the nip portion between the next-stage folding roller 18 and the press roller 17 to form a fold on the third folding plate member 31c. To prevent.
[0039]
The bent portion 71c of the guide plate 71 is linear in the figure, but it may be curved so that the sheet is smoothly guided to the nip portion between the next-stage folding roller and press roller.
[0040]
Next, the operation of the paper folding apparatus configured as described above will be described. In the case of normal paper folding, the folding path member 70 is not installed. First, the folding width of the sheet is determined, the knob 45 is turned, and the position of the stopper 35 is determined while looking at the scale 47 (see FIG. 4). Then, the sheet bundle is placed on the sheet feeding plate 1 and the auxiliary sheet feeding plate 2, and the sheet feeding roller 4 is driven to feed the sheets one by one to the sheet folding unit 9.
[0041]
Then, the sheet is caught by the main roller 10 and the driven roller 11 and enters the first-stage folding plate member 31a, and the leading end of the sheet comes into contact with the stopper 35 of the folding plate member 31a, so that the leading end of the sheet stops. To do. However, since the sheet is continuously fed by the main roller 10 and the driven roller 11, the sheet is bent, and the bent portion is caught in the nip portion between the press roller 13 and the main roller 10. A crease is formed.
[0042]
Next, the sheet is guided by the deflection guide 46 with the first folding portion as the head, and is caught in the nip portion between the second-stage folding roller 14 and the press roller 13, and then the second-stage folding portion. It enters into the folded plate member 31b. Then, the first folded portion comes into contact with the stopper 35 located on the second-stage folded plate member 31b and stops.
[0043]
As a result, the sheet is bent, and the bent portion is caught in the nip portion between the folding roller 14 and the press roller 15 to form a second fold.
[0044]
After that, the second fold is started, and the guide 46 and the nip portion between the press roller 15 and the folding roller 16 enter the third-stage folding plate member 31c. Thereafter, this operation is repeated to form six folds, and a six-fold sheet is obtained as shown in FIGS. 9 (a) and 9 (b). The sheet folded by this folding is discharged from between the folding roller 22 and the press roller to a stacker unit (not shown).
[0045]
Next, a case where the number of folds is reduced and changed as necessary will be described. That is, in this embodiment, a case will be described in which the number of folds is set to 1, and the folding path member 70 is attached to the third-stage folding plate member 31c to obtain a 5-fold sheet. First, the operation lever 54 is pushed in the direction of the arrow, the lock lever 58 is released from the fixed shaft 60, the pair of roller side plates 24 are moved with respect to the apparatus main body, and then the folding plate mounting plate 30 is moved to the fulcrum shaft 63. It is swung until it abuts on the support shaft 65 at the center and is erected. Then, as the number of folds decreases, the folding path member 70 is attached to the unnecessary third-stage folding plate member 31c. After the mounting, the folding plate mounting plate 30 is again swung counterclockwise until it comes into contact with the regulation column 64. Then, the roller side plate 24 is moved and fixed until the notch 58 a of the lock lever 58 is engaged with the fixed shaft 60. Then, the paper feed roller 4 is driven to feed the sheets one by one to the paper folding unit 9. The fed sheet follows the same process as in the case of normal paper folding until the second fold is formed by the second-stage folding plate member 31b. However, the sheet that has passed through the nip portion between the guide 46 and the press roller 15 and the folding roller 16 with the second fold as the head is transferred to the third-stage folded plate member 31c by the bent portion 71c of the guide plate 71. The sheet is prevented from advancing and guided to the nip portion between the folding roller 16 and the press roller 17. In other words, the folding path member 70 prevents the folding of the third-stage folding plate member 31c. Then, the sheet guided to the nip portion between the folding roller 16 and the press roller 17 with the second fold as the head passes through the nip portion between the guide 46 and the press roller 17 and the folding roller 18, and reaches the fourth stage. It enters the folded plate member 31d. Then, the second folded portion comes into contact with the stopper 35 located on the fourth-stage folded plate member 31d and stops. As a result, the sheet is bent, and the bent portion is caught in the nip portion between the folding roller 18 and the press roller 19 to form a third fold. Thereafter, the third fold is advanced, and the guide 46 and the nip portion between the press roller 19 and the folding roller 20 enter the fifth-stage folding plate member 31e. Thereafter, this operation is repeated to form five folds, and a 5-fold sheet is obtained as shown in FIG. 9C. The sheet folded by the folding is discharged from between the folding roller 22 and the press roller 23 to a stacker unit (not shown).
[0046]
In the present embodiment, the reduction in the number of folds has been described as 1. However, when a large number of folds need to be reduced, a plurality of folding path members may be attached to unnecessary folding plate members.
[0047]
In this embodiment, the folding plate member is inserted in the number of folding plate members corresponding to the number of foldings required, and the folding path member is inserted between the other unnecessary number of folding plate members. The front surface of the folding path member 70 is shaped to be suitable for feeding the sheet, and the entrance of the folding plate member is reliably shielded by the folding path member 70, and the sheet is The folded plate member that is guided along the bent portion 71c of the guide plate 71 and passes through without being folded and is not mounted with the folding path member is sequentially normally folded to obtain the required number of folded sheets. The folding path member is attached to the folding plate member by moving the roller mounting plate, swinging the folding plate mounting plate upright, and inserting it into the unnecessary folding plate member. It is held and can be easily installed. When the entrance of the folding plate member for shielding the entrance is opened again as the number of folds increases, the roller mounting plate is moved, the folding plate mounting plate is swung up, the folding path member is removed, and the roller mounting plate is removed. And it is sufficient to return the folded plate mounting plate. Therefore, it is possible to cope with a change in the number of folding sheets very easily.
[0048]
FIG. 11 is a perspective view showing a folding path member 76 according to another embodiment of the present invention, and FIG. 12 shows a state in which the folding path member 76 is mounted on the folding plate member 31 of the paper folding section 9. FIG. 12 shows a state where the paper folding section 9 is erected. The folding path member 76 has springs 77 locked to both ends of the bent portion 71 c, and the other end of the spring 77 is locked to the folded plate member 31. Also in the folding path member 76, the regulation plate 72 is surrounded by the guide member 32 and the folding plate 33 of the folding plate member 31 until the distal end side 71 b of the base portion 71 a comes into contact with the distal end side of the folding plate 33 on the folding roller side. Inserted into the designated space. In this state, the folding path member 75 is supported by the urging force of the spring 77. This example also has the same effect as the folding path member 70 shown in FIG.
[0049]
【The invention's effect】
According to the present invention, since the number of folds can be changed simply by mounting the folding path member in an unnecessary folded plate member, it is very easy to change the number of folds. Also, the folding path member can be mounted very easily, and the folding path member can be mounted and removed very quickly. Furthermore, according to the present invention, the entire apparatus is not enlarged. Further, when the folding path member is mounted, the folding stopper with which the leading end of the sheet abuts is not affected, so that the folding position is not shifted. Furthermore, when changing the number of folds, useless work and labor consumption such as detaching the folding plate member and rearranging the folding roller mechanism are completely unnecessary.
