The continuous paper cutting apparatus as described above further includes
The apparatus is provided with paper feeding means (for example, a paper feeding roller or a pin tractor), paper discharging means (for example, a paper discharging roller or a pin tractor), and control means for controlling the entire apparatus.

Next, the operation of the continuous paper cutting apparatus as described above will be sequentially described mainly with reference to FIGS. 15 to 19, dividing the operation into a standby state, a paper feeding operation, and a cutting operation.

FIGS. 15A, 15B and 15C are left side views for explaining the operation, respectively. FIGS. 16 to 19 mainly show the cutting means 50, the link mechanism 60 for the cutting means, and the link mechanism for the holding means. 70 is a diagram showing the operation of 70, in each of these figures (a) is a left side view, (b) is a right side view,
(C) is a front view of the cutting means 50. FIG.
(D) is a front sectional view showing the relationship between the cutting means 50 and the movable frame 41 of the pressing means 40.

<Standby State> In the standby state, the motor 65 is stopped, and the link mechanism 60 for the cutting means and the link mechanism 70 for the pressing means are in the state shown in FIG. 16, that is, as shown in FIGS. It is in a state of being left.

At this time, as shown in FIG. 4 and FIG. 16 (c), the cutting means 50 is provided with support surfaces 36b, 3 of the continuous paper P of the support means (feeding guide 36 and discharge guide 37).
Pressing unit for 7b (refer h ₃₎ distance of about substantially equal to the distance (see h _2, h ₅₎ of (pressing plate) 42, 42 ', the contact portion 50a supporting surfaces 36b, 37b substantially parallel state ( (Substantially horizontal state).

As described above, the urging force of the urging means 43 is applied to the pressing means 40.
0, and its movement is regulated, and FIG.
It is at the position shown in FIG.

<Paper Feeding Operation> In the above state,
The paper supply unit (not shown) is driven, and the continuous paper P is supplied from the paper supply port 38 onto the cutting space C as shown in FIG.

The continuous paper P is supplied such that the perforations Pa are located substantially at the center of the cutting space C.

<Cutting Operation> The cutting operation is performed by driving the motor 65 so that the drive shaft 61 moves from the standby state shown in FIG. 16 to the state shown in FIG.
It is performed by rotating at a stretch.

Hereinafter, the main states will be sequentially described.

FIG. 17 shows a state in which the drive shaft 61 has been rotated by about 45 ° in the direction of arrow CW from the state shown in FIG.

When the drive shaft 61 starts rotating from the state shown in FIG.
The pressing means 4 is operated by the urging force of the urging means 43 by the operation of
0 starts falling. At this time, the urging force of the urging means 43 acts to assist the rotation of the drive shaft 61 via the link mechanism 70 for the pressing means.

During the rotation of the drive shaft 61, the pressing plates 42 and 42 'of the pressing means 40 abut the paper feed guide 36 and the paper discharge guide 37 via the continuous paper P, and the continuous paper is interposed between these guides. When P is pressed, the urging force of the urging means 43 is received by the paper feed guide 36 and the paper discharge guide 37. Therefore, when the drive shaft 61 further rotates, the second pins 6 of the arms 62L and 62R are rotated.
2L2 and 62R2 are long holes 72 of connecting rods 71L and 71R.
You will slide inside. FIG.
This shows a state in which the drive shaft 61 is further rotated slightly after the zero pressing plates 42 and 42 ′ come into contact with the paper feed guide 36 and the paper discharge guide 37.

On the other hand, from the state shown in FIG.
Starts rotating, the left end 50L of the cutting means 50 starts descending and the right end 50R starts ascending due to the action of the cutting means link mechanism 60 accompanying this. this is,
As shown in FIG. 9B, the position of the first pin 62R1 of the right arm with respect to the periphery of the drive shaft 61 is the first pin 62R1 of the left arm.
This is because the pin 62L1 is shifted by the angle α.

FIG. 17 shows a state in which the right end 50R of the cutting means 50 has completely risen, and also shows a state immediately before the cutting of the continuous paper is started. At this time, the left end 50L of the cutting means 50 is in the position shown in FIGS. 15B and 17C.
As shown in the figure, the left end PL of the continuous paper P is very close to or in contact with the left end PL. As a result, the cutting means 50
As is clear from FIG. 17C, the state is inclined by θ with respect to the paper surface of the continuous paper P.

As shown in FIG. 17D and FIG.
At the right end of the movable frame 41 of the holding means 40, a notch 41f for allowing the cutting means 50 to escape is provided.
Therefore, even if the right end 50R of the cutting means 50 rises,
This does not interfere with the movable frame 41 of the holding means.

The drive shaft 61 is moved from the state shown in FIG.
Starts rotating, the movable guide 80 also rotates, and as shown in FIG. 15B, the cutting means is retracted from the cutting space C in a direction orthogonal to the longitudinal direction of the cutting space C. A passage 50 described later is secured.

When the drive shaft 61 continues to rotate further from the state shown in FIG. 17, as shown in FIG. 18, the operation of the link mechanism 60 for cutting means causes the left end 5 of the cutting means 50 to move.
0L and the right end 50R descend at substantially the same speed (for example, about 8 cm / s). As a result, as shown in FIG. 18 (c), the cutting means 50 continuously moves at an angle θ ′ substantially equal to the aforementioned angle θ. The perforation of the paper P is cut from the left side PL. As described above, since the cutting unit 50 cuts the continuous paper P in an inclined state, the cutting is performed smoothly. Here, θ = θ ′ is not satisfied in FIG.
9B, a distance RL from the center of the drive shaft 61 to the center of the first pin 62L1 of the left arm.
And the distance RR to the center of the first pin 62R1 of the right arm.
Is slightly different, and RL <RR. However, rather, since RL <RR in this way, the cutting means 50 makes a movement almost as if a person grasped the left end 50L and swung it down. It will be cut smoothly from the left side PL.

The pressing means 40 keeps pressing the continuous paper P between the paper feed guide 36 and the paper discharge guide 37 with the same magnitude of urging force of the urging means 43 as in the state shown in FIG. As the drive shaft 61 rotates, the second pins 62L2 and 62R2 of the arms 62L and 62R further move in the elongated holes 72 of the connecting rods 71L and 71R (see FIG. 18).

FIG. 20 is a schematic diagram showing a state in which the continuous paper P is cut (to be exact, a state immediately before the cutting), and corresponds to an enlarged view taken along the line XX-XX in FIG. FIG.

As can be seen from this figure, the continuous paper P is held on both sides of the perforation Pa by the pressing plates 42 and 4.
When the cutting means 50 is lowered in a state where the cutting means 50 is sandwiched and held between the sheet feeding guide 36 and the paper discharge guide 37, the continuous paper P is partially wound around the cutting means 50 with the lowering. In such a state, the continuous paper P is eventually cut (divided) at the perforation Pa by further lowering of the cutting means 50.

Here, the radius of the arc portion of the cutting means 50 is r ₁ , and the winding angle of the continuous paper P with respect to the arc portion is β ₁
Then, the winding length L ₁ of the continuous paper P around the cutting means 50 is L ₁ = r ₁ · β ₁ .

On the other hand, when the continuous paper P is fed, the perforation Pa is not always located exactly at the center of the cutting space C due to a transport error or the like. FIG.
In the figure, the state in which the perforation Pa is located at the center of the cutting space C is drawn by a solid line, but the virtual line Pa ′
Or, as shown by Pa ″, there is a possibility that the center part deviates.

[0065] However, according to the continuous paper cutting device, the contact portion (cut portion) is formed in an arc shape with respect to continuous paper cutting unit 50, since the winding length L ₁ obtained above, the length even if the position of the perforation Pa is deviated within a range of L _1, the continuous paper P is reliably be cut at the perforations Pa.

As the continuous paper P, a copy paper in which a plurality of papers are stacked is often used. As shown by reference numeral 2 in FIG. 26A, the continuous paper P is normally folded in a zigzag state with the perforations as folds, and is fed straight from the folded state. Therefore, if the continuous paper is copy paper, a shift occurs between the stacked sheets (so-called interlayer shift occurs), and as a result, a perforated portion of each sheet also shifts.

FIG. 21 shows this state.

In the same figure, P ′ is three sheets P1,
P2 and P3 are stacked copy paper. When the continuous paper to be cut is such a copy paper P ′, each paper P1, P
The perforations P1a, P2a, and P3a of P2 and P3 are shifted, for example, as shown in FIG.

However, according to this continuous paper cutting device, the contact portion (cut portion) of the cutting means 50 with the continuous paper is formed in an arc shape, and the above-described winding length L ₁ is obtained. is perforation P1a within L _1, P2a, even though misaligned the P3a,
Each of the sheets P1, P2, and P3 of the continuous sheet (copying sheet) P 'is reliably cut at each perforation P1a, P2a, and P3a.

Conversely, in this continuous paper cutting apparatus, the perforation position is shifted from the central portion of the cutting space C due to a continuous paper conveyance error or the like, and / or the continuous paper is copy paper. even perforations of each sheet was shifted from the central portion of the cutting space C, so that its can be reliably cut with perforations, i.e. as described above winding length L ₁ can be obtained, the cutting means 50 The shape of the arc-shaped portion 50a, the paper feed guide 36 and the paper discharge guide 3
7 is set. At least the arc-shaped portion 50a of the cutting means 50 is made of a material having a small coefficient of friction with paper (continuous paper), for example, a galvanized steel plate. This is because the one in which the cutting means 50 is slippery with respect to the sheet is surely cut at the perforation.

As the drive shaft 61 continues to rotate further from the state shown in FIG. 18, the left end 50L and the right end 50R of the cutting means 50 are further moved by the action of the cutting means link mechanism 60 as shown in FIG. 19C at approximately the same speed, and as shown in FIG. 19C, the cutting means 50 completely passes below the continuous paper P, and as a result, the continuous paper P is perforated Pa (FIG. 15C )) Will be completely cut. The reason why the inclination angle θ ″ of the cutting means 50 with respect to the continuous paper P at this time is not the same as the above-described angle θ ′ is as described above.

As in the state shown in FIG. 17, the pressing means 40 presses the continuous paper P with the same magnitude of urging force by the urging means 43.
Is continuously pressed between the paper feed guide 36 and the paper discharge guide 37, and the arm 62 is rotated with the rotation of the drive shaft 61.
The second pins 62L2 and 62R2 of L and 62R move further in the elongated holes 72 of the connecting rods 71L and 71R. In addition,
As shown in FIGS. 19A and 19B, even when the drive shaft 61 is fully rotated, the second pins 62L2 and 62R2 of the arms 62L and 62R and the elongated holes 7 of the connecting rods 71L and 71R.
The long hole 72 is configured such that a small space 72c is formed between the lower hole 2 and the lower end of the second hole 2.

The movable guide 80 rotates with the rotation of the drive shaft 61 as shown in FIG.
To secure the passage.

As described above, the continuous paper P has its perforations Pa
Is completely cut by the drive shaft 61.
Is reversed from the state shown in FIG. 19 to the state shown in FIG. 16, and each member returns to the standby state shown in FIG.

Thereafter, the paper feeding means and the paper discharging means (not shown) are driven, the cut paper CP (see FIG. 15C) is discharged out of the machine, and the next perforated portion is cut into the cutting space C. And the above operation is repeated.

According to the continuous paper cutting apparatus as described above, the continuous paper P is held by pressing the paper pressing means 40 with the urging means 43 against the pair of supporting means 36 and 37, and the continuous paper P is cut. It can be cut by means 50.
