Next, the operation of the present invention will be explained.

As shown in FIG. 1, a continuous sheet of paper a folded into an accordion shape is placed on the mounting plate 1 of the length measuring device A as shown in FIG. 3, and the folded side is cut. It comes into contact with the mounting table C of the device B.

B Regarding the position adjustment between the pin tractors 24 and 24 by measuring the width ₁ of continuous paper a.

As shown in FIG. 6, the phototube 10 transmits light through the transparent plate ₂ from below to detect the presence or absence of continuous paper a. By moving the phototube via the phototube slide drive shaft 11 with the motor 12, the phototube is moved from the time when the light passes through the transparent plate 2 and is blocked by the continuous paper a to the time when the light passes through again. Since this amount corresponds to the amount of movement, the pin tractors 24, 24 in cutting device B
I am trying to adjust and set the position interval of.

For this purpose, a slit plate 1 is provided at the end of the slide drive shaft 11 that rotates as the phototube 10 moves.
The movement of the phototube 10 is determined by counting the number of equally spaced slits with the slit detection device 14 from the time when the light transmittance of the phototube 10 becomes light-blocking until the time when the light-transmissive state becomes light-transmissive again. The quantity is replaced with the number of slits, and the pitch tractor position adjustment drive motor 33 is driven using the detected count signal of the number of slits, and the pin tractor 24,
Adjust the position and set the interval of 24.

Actually, in order to transport the continuous paper a with the pin tractors 24, 24, the continuous through-holes b on both edges of the continuous paper a must be
This is done by engaging the pins 31 of the pin tractors 24, 24, so the pin tractor 2
The distance between 4 and 24 corresponds to the distance between rows of continuous through holes b on both sides that are bored inside the side edges of continuous paper a.

In continuous paper a, the rows of continuous through holes B are constant at 1"/4 inside the side edges, so the distance between the rows of continuous through holes B on both sides, that is, the mutual distance between the pin tractors 24, 24. The spacing is the length of the continuous paper width ₁ minus 1''/4 x 2 = 1''/2.

Therefore, to set the position of the pin tractors 24, 24, the distance obtained by subtracting 1''/2 from the amount of movement of the phototube 10 during light shielding is replaced by a count signal for detecting the number of slits by rotation of the slit plate 13. This is done by controlling the rotation of the pin tractor adjustment drive motor 33 via a control circuit.

(b) Regarding the position setting of the buster rollers 28, 28 by measuring the folding width direction of the continuous paper a.

In order to cut the continuous paper a into single sheets, it is necessary to adjust the position of the buster rollers 28, 28 from the blade 27 depending on the type of the continuous paper a. It is necessary to measure the length ₂ of the folded continuous paper a in the folding direction.

The folded continuous paper a is in contact with the wall surface of the mounting table C of the cutting device B, so the photocell While the phototube 18 of the device 7 remains shielded from light, the phototube slide motor 20 moves it on the phototube slide drive shaft 19, and the amount of movement from the start of the movement to the time when it becomes transparent is determined by the distance from the wall surface.
The distance added by 4″ is the folding width of folding paper a.
It becomes ₂ .

In order to replace this length ₂ with the position setting of the buster rollers 28, 28, the photocell device 6
Similarly to the above, the slit detection device 22 counts the slits of the slit plate 21 provided at the end of the phototube slide drive shaft 19 by the length corresponding to the amount of movement of the phototube 18 plus 4''. Using this as a detection signal, the buster roller position adjustment drive motor 39 is operated via the control circuit.

The rotation of this motor 39 is controlled by a chain belt 40.
is transmitted to the gear 37 of the mounting frame 36, and the gear 3
7 and 37 are moved on the rack rod 38, and the distances of the buster rollers 28 and 28 from the blade 27 are set at adjusted positions.

In this case, since the length of the folded continuous paper a corresponds to the length of the finished cut sheet after one fold is cut, there are at least two cut sheets per fold, and the number of sheets is n (n=
2, 3, ...), the position of the buster rollers 28, 28 to be finished as a single sheet is 1/n of the length measured by the phototube 18 plus 4''. , 1/n of the above length
By pressing the setting switch n via the control circuit, the buster rollers 28, 28 are automatically set to the position for cutting the sheets.

As described above, when the folded continuous paper a is placed on the mounting plate 1 of the measuring device A, the length ₁ in the width direction and the length ₂ in the folded width direction of the paper a are measured.
As a result, the distance between the pin tractors 24, 24, the distance between the slitters 25, 25 interlocked therewith, and the distance of the buster rollers 28, 28 from the blade 27 are automatically adjusted and positioned.

Here, the continuous paper a is reliably transported by the pins 31 of the pin tractors 24, 24 being engaged with the continuous through-holes b on both sides of the paper, and the slitter 25,
At 25, both side edges having continuous through holes b are cut off from the inside thereof, and transfer rollers 26, 26
The buster rollers 28, 28 pass over the guide film 41.
sent to.

Buster rollers 28, 28 are transfer rollers 2
Since the circumferential speed is slightly higher than 6 and 26, the continuous paper a is pulled, and at the moment of this tension, it comes into contact with the blade 27, and a cut is made in the center of the perforation line c of the paper a under tension. By inserting this, this cut instantly expands outward,
Paper a is cut along perforation line c.

The cut sheets are carried out by a carry-out belt 29, raised along an upright 30 installed diagonally, and carried out to the outside.

(Effects of the invention) As explained above, in the present invention, a continuous sheet of paper printed out by a computer, etc. is folded into an accordion shape from the perforation line, and then placed on a length measuring device. Just by placing it on a plate, the length of the continuous paper in the width direction and the length of the folded paper in the width direction are measured using a phototube device, and based on these results, the mutual spacing between the continuous paper feeding devices on both sides, and the length of the continuous paper are determined. Since the position of the buster roller from the blade for cutting the paper can be automatically set, it is possible to very easily cut a single sheet of a predetermined size or a plurality of continuous sheets from continuous paper.
