[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, referring to FIG. 1, a process for making a form 22 by binding, for example, four vouchers each having a size half that of the voucher 20 from a voucher 20 which is a base paper will be schematically described. To do. The form 22 is produced through the following six steps.

(1) Perforation forming step 10 (FIG. 1A)
Here, for each sheet 20 (see FIG. 2) of A4 size plain paper or recycled paper supplied, the sheet 20
Perforations 27 are provided along the binding margin 26 along the left side 25 which is the longitudinal direction of the. This is because it is convenient to separate the slips from the form 22 one by one. Plain paper has a fiber composition.

In addition, the cut sheet 20 is
A line 28 forming a slip and characters 29 such as a date, an address, and a name are printed. The single slip 20 has two slip schedule parts 30 and 31. (2) Moisture Supply Step 11 (See FIG. 1B) Here, an appropriate amount of water is supplied to the binding margin 26 for each sheet 20 to be supplied, and the binding margin 26 is impregnated with moisture. The binding margin 26 is in a state in which all the supplied water soaks into the inside thereof, and water does not float on the surface. The binding margin 26 becomes a moisture-absorbing binding margin 26A,
The single-cut sheet 20 becomes the binding-allowed moisture-absorbed single-cut sheet 20A. The portion that has absorbed moisture is shown in a satin pattern.

Here, the water supply to the binding margin 26 is as follows.
It is not performed at once after stacking the slips, but at each stage before stacking the slips. Therefore, even when the number of slips to be stacked (stitched) is large, if the moisture is supplied after stacking the slips, the moisture in the central portion, which is difficult for water to spread, will be in a state of appropriately absorbing moisture. .

(3) Cutting Step 12 (Refer to FIG. 1C) Here, the binding and moisture absorbing single-cut sheet 20A is shown in FIG.
Inside, a planned cutting line 32 at the boundary between the two voucher planning sections 30 and 31
Cut along. As a result, the binding margin / moisture-absorbing cut sheet 20A becomes two binding margin / moisture-absorbing slips 33 and 34 of the same size, which is the A5 size.

(4) Alignment and stacking step 13 (see FIG. 1 (D)) Here, two binding margin and moisture absorbing slips 33 and 34 obtained from the first binding margin and moisture absorbing cut sheet 20A, and two sheets The two binding margins and moisture absorbing slips 35 and 36 obtained from the stitch binding and moisture absorbing single cut sheets are overlapped with the respective moisture absorbing binding slips 26A aligned.

(5) Binding step 14 (see FIG. 1 (E)) Here, a plurality of bound binding margins and moisture-absorbed slips 3 are stacked.
Pressure is applied from a vertical direction to binding points (screws) having a triangular cross section in a vertical direction at a total of three places near the center and both ends of the moisture-absorbing binding margins 26A of 3,34,35,36. . As a result, as shown in FIG.
The fibers of the paper are entangled between the overlapping moisture-absorbing binding margins 26A, and the four binding margin moisture-absorbing slips 33, 3
4, 35 and 36 are bound.

Reference numerals 40, 41 and 42 are binding portions. Here, since the water is supplied to the binding margin 26 not at a time after stacking the slips but at a stage before stacking the slips, the slips 26 are stacked one by one. When the water is supplied after the moisture is supplied, the fibers of the paper are also entangled between the moisture-absorbed binding margin 26A of the two central slips 34 and the moisture-absorbed binding margin 26A of the slip 35, which is normally hard to spread the moisture. Therefore, the four binding margin and moisture absorbed slips 33, 34, 35, and 36 are firmly bound with a sufficiently strong binding force in a dry state.

(6) Punching step 15 (see FIG. 1G) Here, the slips 33 and 3 bound by punching are used.
Holes 43 and 44 for files are drilled in the portions along the perforations 27 of 4, 35 and 36. As a result, the form 22 is completed.

The moisture-absorbed binding margin 26A is then naturally dried to the original binding margin 2 in the dried state.
6, the form 22A (see FIG. 2) is obtained. Binding section 4
Nos. 0, 41, and 42 are dried in a state where the fibers of the paper are entangled well, and the slips 33, 34, 35, and 36 are firmly bound with a sufficiently strong binding force.

Next, a form preparing apparatus 50 which is an embodiment of the document preparing apparatus of the present invention will be described. FIG. 2 shows the appearance of the form manufacturing apparatus 50. 3 and 4 show the internal structure of the form making apparatus 50 shown in FIG.

The voucher 20 is sent out from the upper position of the front surface of the form making device 50, and advances inside the form making device 50 along a substantially U-shaped path in FIG. 3 to form a form 22 (22A). ,
It is sent out from the lower position on the front surface of the form making apparatus 50.

The tray 51 is used to prepare the form.
Then, a large number of the single-cut sheets 20 shown in FIG. 1 (A) are placed. The cut sheet 20 is made of A4 size plain paper,
Lines and characters forming a slip are printed, and two slip schedule portions 30 and 31 are provided. In addition, by operating the operation panel 61, for example, the two cut sheets 20 are cut into two,
A command for producing the spelled form 22 is input.

When the start button is pressed, the form making device 50 is started, and the cutting rollers 62 constituting the paper feeding device 52 cause the upper two of the plurality of single-cut sheets 20 placed on the tray 51. Vouchers 20 are sent out one by one,
It is sent in the Y1 direction and reaches the perforation forming device 53. [Perforation forming device 53] The perforation forming device 53 has a structure in which a perforation roller 64 supported by a block 63 is pressed against a roller 65, and is arranged on the X2 side in FIG. In the cut sheet 20, the portion near the left side 25 passes between the perforation roller 64 and the roller 65, and
As shown in (A), perforations 27 are put in a portion along the left side 25.

The cut sheet 20 in which the perforations 27 have begun to reach the water supply device 54. [Moisture Supply Device 54] The moisture supply device 54 is shown in FIG.
And a water tank 71 in which water 70 is stored,
A pulley 72 located in the water 70 of the water tank 71, a drive pulley 73 arranged next to the roller 65, a belt 74 stretched between the pulley 72 and the drive pulley 73, and a drive The rubber roller 75 is located immediately above the pulley 73 and is in contact with the belt 74 wound around the drive pulley 73. The belt 74 is
The width W2 is substantially the same as the width W1 of the binding margin 26 in FIG. As shown in FIG. 4, the belt 74 is arranged at a position slightly closer to the X2 side than the perforation roller 64.

As shown in FIG. 5B, the outer surface 74a of the belt 74 has a cloth-like shape. Belt 7
When the water 4 comes out of the water 70, the water does not become droplets of a visible size and disperse and adhere, but FIG.
This is to ensure that water adheres in the state of an extremely thin water film 76 as shown in (C). That is, the belt 74 is
It has a role of continuously supplying the water 70 in the water tank 71 in the direction of the rubber roller 75 in the state of an extremely thin water film 76.

The drive pulley 73 is rotated clockwise, the belt 74 is running in the direction of arrow A1, and the binding margin 26 portion of the cut sheet 20 is the belt 74 and the rubber roller 75 wound around the pulley 73. Sandwiched between and sent in the Y1 direction. When the portion of the binding margin 26 passes while being sandwiched between the belt 74 and the rubber roller 75, the extremely thin water film 76 attached to the cloth-like outer surface 74a of the belt 74 and carried. , Is attached so as to be transferred to the lower surface of the binding margin 26. The water attached to the binding margin 26 is
Soaking in the fiber composition of the binding margin 26, the binding margin 26
Becomes the moisture-absorbed binding margin 26A in a state in which the fiber becomes wet and the fibers are slightly loosened.

Here, since the water film 76 is continuously carried by the belt 74, the water adheres uniformly over the entire length of the binding margin 26. As a result, the binding margin 26
Has a state in which water is uniformly impregnated in the fiber composition over its entire length. In addition, since the water film 76 is extremely thin, the amount of water attached per unit area of the binding margin 26 is extremely small, which is slightly less than the amount of water that the fiber composition of the binding margin 26 can absorb. Therefore, all the water adhering to the binding margin 26 is soaked in the fiber composition, and a slight amount of water does not float on the surface of the binding margin 26.

Further, since the water film 76 is carried by the belt 74, the water can be surely adhered to the binding margin 26 only. The single-cut sheet 20 in which the binding margin 26 has become the moisture-absorbed binding margin 26A subsequently reaches the cutting device 55.

[Cutting Device 55] The cutting device 55 is shown in FIG.
Inside, a sensor 80 that detects the leading edge of the binding margin and moisture absorbing cut sheet 20A that is conveyed, a fixed blade 81 that covers the entire width of the cut sheet 20A, a movable blade 82 that moves in the direction of the arrow, and a stepping motor (not shown) And the like.

The number of steppings of the stepping motor (not shown) is counted from the time when the sensor 80 detects the leading end of the conveyed single-cut sheet 20A, and the stepping motor is temporarily stopped when the stepping number reaches a predetermined number. Let Here, the predetermined number is the number required to convey the single-cut sheet 20A until the line 32 in FIG. 1B reaches the position of the fixed blade 81. Subsequently, the movable blade 82 is rotated in the direction of the arrow by the drive mechanism (not shown), and the single-cut sheet 20A moves to the line 32.
Is cut along.

As a result, the single sheet 20A with the binding margin and moisture absorption is completed.
Will be two binding margin and moisture absorbed slips 33 and 34 of the same size, which are A5 size. The binding margin and moisture-absorbed slips 33 and 34 reach the aligning and stacking device 56 next. Following the slips 33 and 34 with the binding margin and moisture absorption, the second single sheet 2
The binding and moisture absorbing slips 35 and 36 obtained by cutting 0A reach the aligning / placing device 56.

A roller 146 is attached to the other end of the press arm 141. The screw 145 is opposed to the screw 143 with a gap 148, and the roller 146 is in contact with the eccentric cam 142. The screws 143 and 145 form a binding member.

The eccentric cam 142 is rotatably supported by a fixed shaft 147 on the frame of the form manufacturing apparatus 50.
The stacking slip 120 is transported by the transport mechanism 130, and the moisture-absorbed binding margin stacking part 121 passes through the gap 148. Moisture absorption binding margin stacking part 121 has a gap 148
In the process of passing through, the transport mechanism 130 is temporarily moved three times, that is, at the position where the moisture-absorbed binding margin stacking part 121 has entered the gap 148, the position where it has entered the central part, and the position before it exits. Stop at. The eccentric cam 142 makes one rotation at a predetermined speed each time it is temporarily stopped, and pushes the roller 146 to rotate the press arm 141 in the arrow D direction. The press arm 141 operates on the principle of leverage, in which the roller 146 side is a force point, the fixed shaft 144 is a fulcrum, and the screw 145 is an action point. A strong force is generated in the screw 145, which is the point of action, and the moisture-absorbed binding margin stacking portion 121 is sandwiched between the screw 143 and the screw 145. The binding device 57 is
The screw 143 is configured to apply the pressure necessary for the entanglement of the stacked binding margin fibers for a suitable period of time.

As a result, as shown in FIG. 1 (E), the three binding sections 40, 4 are formed on the moisture-absorbed binding margin stacking section 121.
1 and 42 are formed, and the moisture-absorbed binding margin stacking portion 121 is bound at three locations. Regarding the state of the binding section 40 etc.,
It will be described later. [Punching Device 58] The punching device 58 has a punch 150.

The stacking slip 120 is temporarily stopped in the process of passing through the binding device 57. At this time, the punching device 5
8 is driven and the punch 150 moves downward. This allows
Stacked slip 1 in which the binding portion 40 and the like are formed and being bound
A hole 4 for a file is provided at a portion along the perforation 27 of 20.
3,44 are opened.

As described above, a 4-sheet binding, 3-location binding, 2-hole form 22 is produced by processing two A4 size sheets. The binding portions 40, 41, 42 are formed, and
The form 22 produced by making the holes 43 and 44 is carried by the carrying mechanism 130, discharged as shown in FIG. 3, and housed in the housing case 59.

The moisture-absorbed binding margin stacking portion 121 is
Then, it is naturally dried to be in a dried state, and the form 22A is completed. Next, the states of the binding section 40 and the like will be described. First, the screws 143 and 145 forming the binding portion 40 will be described with reference to FIG.

The screws 143 and 145 are both screws having a diameter of 5 mm. The screw 143 has a protrusion 160 with a triangular cross section.
And a concave portion 161 having a triangular cross section are alternately arranged. The screw 145 also has a convex portion 162 having a triangular cross section.
And a concave portion 163 having a triangular cross section are alternately arranged.

The screws 143 and 145 are the same as the screws 143.
The convex portion 160 and the concave portion 163 of the screw 145 face each other, and the concave portion 161 of the screw 143 and the convex portion 162 of the screw 145 face each other. FIG. 13 (A),
(B), (C) is a figure explaining formation of the above-mentioned binding part 40. 13 (D), (E), and (F) are diagrams showing a state in which the binding margin is bound without absorbing moisture, and FIG.
3 (A), (B), and (C).

First, the state in which the binding margin is bound without absorbing moisture will be described. 121B in FIG.
Is a binding margin stacking part, and four binding margins 26-1 to 26-4 which are not absorbed are stacked. Screw 1
When 43 is pushed with a predetermined force F, as shown in FIG.
The binding margins 26-1 to 26-4 include a convex portion 162 and a concave portion 16.
A little stretches along the shape of 1 and a crack 170 occurs immediately. Subsequently, as shown in FIG. 6F, the binding margin stacking portion 121 is compressed, and the edges of the binding margins 26-1 to 26-4 facing the crack 170 are indicated by reference numerals 171 and 172. And the binding margins 26-1 to 26-1 immediately below or immediately above
26-4 bites into and can be caught, binding section 40B
Is formed.

Finally, the distance between the screws 143 and 145 is L1. On the other hand, when the moisture-absorbed binding margin stacking part 121 in which the moisture-absorbed binding margins 26A-1 to 26A-4 that have been made to absorb moisture are stacked is bound as shown in FIG. As shown in (B) and (C).

Moisture Absorbed Binding Margins 26A-1 to 26A-4
Is in a soft state where fibers are loosened by absorbing water, so when the screw 143 moves downward from the state of FIG. 13 (A) and is pushed with a predetermined force F, as shown in FIG. 13 (B). To
The moisture-absorbed binding margins 26A-1 to 26A-4 are the convex portions 16
2 and the concave portion 161 extend along the shapes thereof. Here, since the moisture-absorbed binding margins 26A-1 to 26A-4 are in a soft state in which the fibers are slightly unraveled by absorbing moisture, the fibers are unraveled without cracks, and thus the reference numeral 17
Fully stretched as shown at 4.

Then, as shown in FIG. 7C, the fibers of the paper are further loosened, and due to the compressive force, the loosened fibers are entangled and caught between the overlapping binding margins 26A-1 to 26A-4. As a result, the binding portion 40 is formed. 17
5 is a part where fibers are entangled.

Finally, the distance between the screws 143 and 145 becomes L2. Moisture Absorbing Binding Margin 26A-1 to 26A
-4 is soft because it absorbs water,
It is more compressed than when dry, so L2 is L1
Smaller. The moisture-absorbed binding margin stacking portion 121 is further compressed as compared with the case where it is dry, so that the loosened fibers between the overlapping binding margins 26A-1 to 26A-4 have a strong entanglement. Therefore, the binding force of the binding portion 40 is larger than the binding force of the binding portion 40B, as will be understood from the experiment described later.

Here, the binding between the binding margins 26A-2 and 26A-3 located in the center of the moisture-absorbed binding margin stacking portion 121 will be examined. Water is supplied at a stage of each sheet before stacking. Therefore, the binding margins 26A-2, 2
6A-3 is also in a sufficiently hygroscopic state. Therefore, the loose fibers are often entangled between the binding margins 26A-2 and 26A-3, and the binding force between the slip 34 and the slip 35 is
It is as strong as the binding force between the slips 33 and 34 and the binding force between the slips 35 and 36.

Next, the binding force of the binding portion 40 and the binding portion 40
The result of the experiment comparing the binding force of B will be described.
In the experiment, as shown in FIG. 14, slips 200 and 201 obtained by cutting an A4 size PPC paper having a continuous weight of 55 kg into two sheets, one with a binding margin absorbed and one without moisture absorption were prepared. As described above, five sheets are formed by binding one place, binding two sheets, and binding one place, holding the slip 200, turning over the slip 201, and pulling with the spring scale 210.
The display value (this is called binding force) of the spring scale 210 when the slip 201 was peeled off was read.

The results of the experiment are shown in FIG. When the binding margin is bound without moisture absorption, the average binding force is as small as 68 g, whereas when the binding margin is absorbed and bound, and then dried, the average binding force is 599 g. That is, it is as large as about eight times the binding force when binding the binding margin without absorbing moisture.

Immediately after binding the binding margin with moisture,
That is, even before drying, the average binding force is 156 g.
Is larger than the binding force when binding the binding margin without absorbing moisture. When the above-mentioned form 22 becomes unnecessary, it can be shredded in this state. Therefore, it is possible to simply and safely dispose of the prepared form 22.

Further, the above-described form producing apparatus 50 operates the operation panel 61 to change the cutting size of the paper,
Several patterns can be set regarding the binding position, the presence / absence of holes for files, and the like. In addition, the perforation forming device 5
It is also possible to make 3 etc. optional.
