2. Description of the Related Art Conventionally, in a continuous paper cutting apparatus of this type, a cutting operation by a tension applying unit including a pair of upper and lower infeed rollers and a high-speed roller, and a cutting auxiliary unit is performed by cutting a continuous paper that has been input in advance. In general, the control is performed according to the size, and the thickness of the continuous paper is not considered.

Problems to be Solved by the Invention For this reason, conventionally, according to the thickness of the continuous paper,
When the continuous paper is thicker than the standard, the upper and lower intervals of each roller at the time of cutting will be relatively wide or narrow, and the cutting will be performed before reaching the contact position of the pair of upper and lower high speed rollers. On the other hand, if the continuous paper is thinner than the standard, the cutting operation is not performed even if the continuous paper reaches the contact position of the pair of upper and lower high-speed rollers. For this reason, there has been an inconvenience that it is difficult to perform an accurate cutting operation only by controlling according to the cutting size of the continuous paper.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a continuous paper cutting apparatus capable of performing an accurate cutting operation in response to a difference in paper thickness.

By means of a continuous paper cutting device that cuts the continuous paper at predetermined perforations, the cutting size that is the length between predetermined perforations to be cut of the continuous paper is automatically measured. Or, by manual input operation using a keyboard or the like, the sheet cutting size input means to be input and the thickness of the continuous paper Alternatively, the tension applying means and the cutting assisting means are continuously connected based on a sheet thickness inputting means which is manually input, and an input signal input by the paper cutting size inputting means and an input signal input by the paper thickness inputting means. Cutting timing setting means for automatically setting the cutting timing for the sheet.

In the case of a so-called fixed type cutting device,
That is, a pair of in-feed rollers which are arranged so as to be relatively movable in the direction of contact and separation at predetermined intervals vertically, and are similarly arranged so as to be relatively movable in the direction of contact and separation at predetermined intervals vertically. A pair of high-speed rollers that rotate at a higher speed than the in-feed roller, and cutting assist means such as a blade disposed between the pair of rollers. And cutting the continuous paper into a predetermined length by giving a trigger for cutting by contacting the continuous paper with the cutting assisting means by utilizing a difference in transport speed of the pair of rollers with respect to the continuous paper. For the device,

On the other hand, if the cutting device is not a so-called fixed type, the cutting timing setting means is configured to automatically adjust the distance between the high-speed roller of the tension applying means and the cutting auxiliary means to set the cutting timing for continuous paper. do it.

Based on the cut size and thickness of the continuous paper that has been input, the timing of cutting the continuous paper by the tension applying means including a pair of upper and lower in-feed rollers and a high-speed roller and the cutting auxiliary means such as a blade is determined. The control makes the cutting operation accurate. In the case of a fixed type cutting apparatus, the cutting operation can be performed more accurately by detecting the sheet thickness in a state where the continuous sheet is actually held between a pair of upper and lower rollers.

The cutting device comprises a pair of upper and lower infeed rollers 26a, 26b opposed to each other at an interval of about 1 to 1.5 mm movably in the contact and separation directions, and a predetermined interval in the transport direction with the infeed rollers 26a, 26b. A pair of upper and lower high-speed rollers 27a and 27b, which are also arranged at an interval of about 1 to 1.5 mm so as to be freely movable in the contact and separation directions, and these in-feed rollers 26a and 26b and the high-speed rollers 27a and 27b. And a plate-like blade 28 for contacting each folding / cutting perforation 2 of the continuous paper 1. The pair of upper and lower in-feed rollers 26a and 26b and the high-speed rollers 27a and 27b constitute tension applying means, and the blade 28 constitutes cutting assist means. In the vicinity of the high-speed rollers 27a, 27b of the blade 28,
A paper leading edge detector 29 is provided.

Next, a moving mechanism for moving the in-feed rollers 26a and 26b and the high-speed rollers 27a and 27b in the approaching direction and the thickness of the continuous paper 1 are set to "thick", "medium", and "thin".
The sheet thickness detecting device as the sheet thickness input means or the sheet thickness detecting means for detecting in three stages will be described.

As shown in FIG. 2, the lower infeed roller 26b
The rotating shafts 30 and 31 provided eccentrically to the upper high-speed roller 27a and the rotating shafts 30 and 31 provided to the machine frame 25 (see FIG. 3) are connected to the machine frame 25 (see FIG. 3). ) Are rotatably supported by bearings (not shown) provided in each of the driven pulleys, and driven pulleys 32 and 33 are mounted concentrically. The driven pulleys 32 and 33 and a rotary solenoid 34 (third
An endless belt 46 is stretched over a drive pulley 35 fixed to the output shaft (see the figure). As shown in FIG. 1, the rotary solenoid 34 is connected to the CPU 19 serving as cutting timing setting means or approach timing control means.
The output shaft is rotated by a predetermined amount in a predetermined direction by a drive control signal from the PU 19. Therefore, the driving pulley
35 also rotates by the same amount in the same direction as the output shaft, and this is transmitted to the driven pulleys 32 and 33 by the endless belt 46. Each of the driven pulleys 32, 33 respectively corresponds to each of the rotating shafts 30,
By rotating around the center 31, each roller 26b, 27a
Make circular motions in the same direction. For this reason, when the drive pulley 35 is rotated clockwise in FIG. 2 by the rotary solenoid 34, the roller 26b rises, the roller 27a descends, and the rollers 26a, 27b
, While the drive pulley 35
In the figure, when the rotation is returned in the counterclockwise direction, the roller 26b is lowered, and the roller 27a is raised and returns to the original position. As a result, the rotation amount of the output shaft of the rotary
By controlling with U19, the in-feed rollers 26a, 26b
The upper and lower intervals of the high speed rollers 27a and 27b are adjusted.

More specifically, as shown in FIG. 5, a voltage of −12 V is applied to the rotary solenoid 34 when not operating, and when a voltage of +45 V is applied, the output shaft moves clockwise in FIG. By rotating, the roller 26b rises, the roller 37a descends, and moves in the approaching direction to the rollers 26a and 27b which are opposed to each other. By rotating in the counterclockwise direction in FIG. 2, the roller 26b is lowered, the roller 27a is raised, and moves in a direction away from the rollers 26a and 27b that are opposed to each other.

As is apparent from FIGS. 2 and 3, the driving pulley 35 is fixed with a rotating plate 42 as a displacement member that is rotated and displaced in accordance with the rotation of the driving pulley 35. A notch 43 is formed at the tip, and a contact portion is formed on one side.
42a is integrally bent. The contact portion 42a contacts the stopper 45 in the standby state to determine the initial position of the rotary plate 42. On the other hand, an optical sensor 44 is attached to the machine casing 25, and a detection unit (× in FIG.
The detection recess 44a having the mark () is located at a position corresponding to the movement path of the tip of the rotating plate 42. Then, the optical sensor 44
Detects the amount of rotation of the rotating plate 42 in three stages based on the displacement position of the notch 43. In the first stage, the rotating plate 42 rotates clockwise from the initial state position in FIG. The notch 43 does not reach the detection unit, and the second step is the notch 43
The third stage is a stage in which the notch 43 has passed through the detection unit (the state shown in FIG. 2). Then, since the rotating plate 42 returns to the initial state position again from the maximum rotating position, the number of detections of the notch 43 is 0 in the first stage, and the number of detections of the notch 43 is 1 in the second stage. In the third stage, the number of times the notch 43 is detected is two.
The optical sensor 44 uses the detection of the notch 43 as a detection signal as the CPU 1
9, the CPU 19 determines the thickness of the continuous paper 1 in three stages according to the number of inputs of the detection signal. If the number of inputs is 0, it is "thick", and if the number of inputs is 1, it is "medium". If the number of inputs is two, it is determined to be "thin". In a state where the paper thickness is not detected, the CPU 19 is configured to perform the control operation by setting the paper thickness to “medium”.

As shown in FIG. 1, following the cutting device, there is provided a stacker device for sequentially stacking the cut unit sheets 1a. The stacker device includes a vertically movable elevating table 36 on which the unit paper 1a is placed, and a transporting direction at a speed higher than the paper unloading speed by the cutting device to reliably stack the unit papers 1a on the elevating table 36 sequentially. A carry-in guide belt 37 having two parallel narrow belts rotated and rotated.
The position of the uppermost unit paper 1a stacked on the elevating table 36 is detected, and when it is higher than a certain position, a detection signal for lowering the elevating table 36 is sent to the CPU 1.
9 is provided with a paper stack amount detector 38 to be sent.

Next, the operation of the present embodiment configured as described above will be described.

First, as shown in FIG. 1, the continuous paper 1 is placed at a predetermined position on the mounting table 3 in a predetermined folded state, and a measurement operation for inputting a unit paper size is performed. This measurement operation is performed in the seventh
As shown in FIG. 8 and FIG. 8, the driving is performed by driving the driving motors 13 and 13a, rotating the rotating shafts 11 and 11a, and moving the photoelectric tubes 12 and 18 along the shafts 11 and 11a. . Here, the photoelectric tube 12
The amount of movement from the time when the light is transmitted through the light transmitting plate 7 and is blocked by the continuous paper 1 to the time when the light is transmitted again corresponds to the length of the continuous paper 1 in the width direction. apparatus
At 15, the number of slits from the point at which the light was
The counting is performed until the light is transmitted again, and this count is replaced by the amount of movement of the photoelectric tube 12 and is used as a detection signal by the CPU 19.
Output to The CPU 19 sends a drive control signal based on the detection signal to the motor 40, and the tractor
Adjust the facing interval of 20 to the width of the continuous paper 1. On the other hand, the photoelectric tube 18 is already shielded from light at the movement start position when the continuous paper 1 is placed in the predetermined state, and therefore, the amount of movement from the start of movement to the point of light transmission is determined by the slit detection device 15a. The number is counted from the above-described movement start time to the light transmission time, and the movement amount obtained by replacing the counted number and the distance from the end of the continuous paper at the initial position of the photoelectric tube 18 are added to obtain the continuous paper 1 Of the fold width, that is, the cut size, and outputs it to the CPU 19 as a detection signal. And this detection signal is
Is stored in the memory.

Subsequently, the continuous paper 1 is pulled up, the marginal holes 6 and 6 are engaged with the tractor 20 of the tractor 20 whose facing distance is adjusted, and the main motor 21 is driven. Thereby, the continuous paper 1 is transported rightward in FIG. 1, the marginal portions 5, 5 are cut off by the slitter 24, and further transported. The transport speed of the continuous paper 1 is detected by the detector 23, sent to the CPU 19, and stored in its memory.

Next, the continuous paper 1 is transferred to a cutting device, and when the continuous paper 1 is sandwiched between the in-feed rollers 26a and 26b and the high-speed rollers 27a and 27b, the paper thickness is detected and a cutting operation is performed. Here, in the first cutting operation, since the sheet thickness has not been detected, the CPU 19 sets this to “medium” and controls the cutting operation, and the second and subsequent cutting operations are performed on the sheet detected at the first cutting operation. It is controlled by the CPU 19 based on the thickness.

The control for adjusting the vertical distance between the in-feed rollers 26a, 26b and the high-speed rollers 27a, 27b by the CPU 19 based on the thickness detection will be described with reference to FIGS. 4 and 5. FIG.

The infeed rollers 26a, 26b and the high-speed rollers 27a, 27b are respectively moved in the approaching direction by the drive timing (standard timing) of the rotary solenoid 34 whose paper thickness is controlled to be "medium" by the CPU 19,
The continuous paper 1 is pinched. At this time, the notch 43 of the rotating plate 42 is detected by the optical sensor 44, and a detection signal is sent to the CPU 19 (step 101). Here, if the detection signal is input twice and it is determined that the sheet thickness is "thin" (step 10).
2), the drive timing of the rotary solenoid 34 is set earlier (step 103). According to this advance timing, as is apparent from FIG. 5, after the leading edge detection signal of the continuous paper 1 by the leading edge detector 29 is input to the CPU 19, the standard (“medium”) corresponding to the paper transport speed and the cutting size is used. The predetermined time t ₁ earlier than the timing of
A drive signal is output to the rotary solenoid 34, that is, a voltage of +45 V is applied. Therefore, the interval when the continuous paper 1 reaches the rollers 26a, 26b and 27a, 27b is set to be narrower than the standard (in the case of "medium").

If it is determined in step 102 that the sheet thickness is not “thin”, it is determined in step 104 whether the sheet thickness is “medium”.
Here, if the detection signal is input once and it is determined to be "medium", the drive timing of the rotary solenoid 34 is set to the standard timing (step 105). According to this standard timing, as apparent from FIG. 5, after the leading edge detection signal of the continuous paper 1 by the paper leading edge detector 29 is input to the CPU 19, the rotary is rotated at a normal timing according to the paper transport speed and the cutting size. A drive signal is output to the solenoid 34, that is, a voltage of +45 V is applied. The interval between the rollers 26a, 26b and 27a, 27b at this time is a standard interval.

If it is determined in step 104 that the paper thickness is not “medium”, it means that no detection signal is input, and
In step 106, processing is performed as "thick", and the drive timing of the rotary solenoid 34 is set to a later timing (step 107). According to this delay timing, as is apparent from FIG. 5, after the leading edge detection signal of the continuous paper 1 by the paper leading edge detector 29 is input to the CPU 19, the standard ("medium" the predetermined time t ₂ later than the timing when) the "output of the drive signal to the rotary solenoid 34, i.e. + 45V voltage application is performed. Therefore, when the continuous paper 1 reaches the rollers 26a, 26b and 27a, 27b, the rollers 26a, 26b and 27a, 27
The interval of b is set wider than the standard ("medium").

In this way, when the thickness of the continuous paper 1 is detected, and the leading edge detection signal is input to the CPU 19, the CPU 19 uses the thickness detection signal based on the already input transport speed and cutting size of the continuous paper 1. A drive signal is output to the rotary solenoid at the corrected timing. Thereby, the vertical intervals of the in-feed rollers 26a, 26b and the high-speed rollers 27a, 27b become appropriate intervals according to the sheet thickness when the continuous sheet 1 is transferred to a predetermined position,
The blade 28 abuts the folding / cutting perforation 2 of the continuous paper 1 to which tension has been applied by the in-feed rollers 26a, 26b and the high-speed rollers 27a, 27b, and the continuous paper 1 is cut into unit paper 1a. You.

Immediately after the cutting is completed, a voltage of -45 V is applied, and the rollers 26b and 27a are moved in the separating direction. The timing for moving the rollers 26b and 27a in the separating direction is the same time immediately after the completion of cutting regardless of the paper thickness.
The timing for applying the voltage of −12 V is the same regardless of the paper thickness.

Then, the cut unit paper 1a is fed into the carry-in guide belt.
By 37, they are sequentially stacked on the elevating table 36. Here, when the position of the uppermost unit sheet 1a is higher than a predetermined height position, it is detected by the sheet stack amount detector 38, a detection signal is sent to the CPU 19, and the elevation table 36 is moved by a predetermined distance. It is lowered, and a smooth stacking operation is always performed.

Next, the present invention is not a fixed type cutting device,
That is, rather than adjusting the timing of moving the pair of upper and lower in-feed rollers and the high-speed roller, which are tension applying means, in the approaching direction, and setting the cutting timing, cutting is performed with any pair of rollers of the tension applying means. A preferred embodiment applied to a cutting device for setting a cutting timing by adjusting the distance to the auxiliary means will be described in detail with reference to FIG.

The difference between the cutting device of the present embodiment and the above-described embodiment is that the pair of upper and lower rollers controlled by the approach timing control unit is controlled by the cutting timing setting unit instead of the moving mechanism that moves the pair of rollers in the contact and separation directions. This is the point that a moving mechanism for the high-speed rollers 27a, 27b for automatically adjusting the distance between the high-speed rollers 27a, 27b of the tension applying means and the blade 28 as the cutting auxiliary means is provided. Therefore, the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted. Also,
The general components of the continuous paper processing apparatus are not shown, and only the main parts are shown and described.

The high-speed rollers 27a and 27b are a pair of left and right frames 50.
(Only one shown) is rotatably supported by the frame
Rotation gears 51 and 52 are rotatably provided on 50, and a drive motor 53 that is a rotation drive source of each of the rotation gears 51 and 52 is attached. The drive motor 53 is connected to a CPU 54 serving as a cutting timing setting means, and is configured to be driven and controlled. The rotating gears 51 and 52 mesh with a rack gear 55, and the driving motor 53
The frame 50 moves in the horizontal direction in FIG. 10 by being driven to rotate in a predetermined direction under the control of the CPU 54. Note that the other rotating frame and rack gear are also provided for the other frame (not shown). Therefore,
By controlling the drive of the drive motor 53 by the CPU 54, the blade 28 and the high-speed rollers 27a, 27b
Is adjusted.

Further, the CPU 54 is configured such that the cut size and the sheet thickness are input from a keyboard device 56 which also serves as a sheet cut size input unit and a thickness input unit. The sheet transfer speed is configured to be input from a detector 23 of a tractor encoder 22 that detects the rotation speed of the tractor 20, as in the first embodiment described above.

Since the present embodiment is configured as described above, the CPU 28 causes the blade 28 and the high-speed rollers 27a, 27a, based on the cut size and the sheet thickness input from the keyboard device 56 and the sheet transfer speed input from the detector 23. By adjusting the distance to 27b, an appropriate cutting timing can be set. That is, in the same manner as in the first embodiment described above, the case where the paper thickness is medium is standard, and when the paper thickness is thin, the blade 28 and the high-speed roller
The distance between the blade 28 and the high-speed rollers 27a and 27b may be controlled so that the distance between the blade 28 and the high-speed rollers 27a and 27b is greater when the sheet is thicker than when the sheet is medium.

The present invention is not limited to the above-described embodiments.For example, the drive source for reducing the vertical distance between the in-feed rollers 26a, 26b and the high-speed rollers 27a, 27b is not limited to the rotary solenoid 34. Alternatively, a pulse motor or the like may be used. Further, as the cutting assisting means, other than the plate-like blade 28, a member having a shape in which the central portion in the longitudinal direction has the maximum diameter and gradually reduces the diameter toward both ends may be used, and the shape is not limited at all. Not done. In addition, tractor 20
Alternatively, the continuous paper 1 can be transported by a roller or the like. The paper thickness input means measures the paper thickness with a paper thickness gauge provided integrally with or separately from the present apparatus, and automatically inputs the paper thickness from the paper thickness gauge or manually inputs the data using an input device such as a keyboard. May be used. Furthermore, the length of the continuous paper 1 in the width direction need not always be measured, and the configuration of the paper size measuring apparatus may be variously changed, for example, the measurement may be performed using elements other than the photoelectric tubes 12 and 18. . Further, by providing a plurality of notches 43 of the rotating plate 42, it is possible to detect the paper thickness in more steps. The displacement member is not limited to the rotating plate 42, of course.

Effects As is apparent from the above description, according to the present invention, the cutting size of the continuous paper is input, the paper thickness is also detected, and a pair of upper and lower infeed rollers and a high-speed roller are detected based on these results. Are brought close to each other in the vertical direction, so that the continuous paper can be cut accurately at a desired position. Further, in the fixed-type cutting device, by detecting the sheet thickness in a state where the continuous sheet is actually sandwiched between the pair of rollers, there is an effect that the cutting accuracy can be further improved.
