Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding delivery device for vertically stacking continuous sheets, such as continuous forms, having perforations at regular intervals by zigzag folding along the perforations.

[0002]

2. Description of the Related Art A continuous form produced by a rotary press printing machine, a collator or the like has a paper folding device as shown in FIG. 4 provided on the discharge side of the printing machine, the collator or the like, and is continuously perforated. The paper 101 is transferred to the nozzle pendulum 103 by the paper feed tractor 102, ejected while being swung left and right by the nozzle pendulum 103, and the flyers 104a and 104b are ejected.
Further, the belts are folded like bellows by the screws 105a and 105b, and are conveyed by the belt conveyer in the form of overlapping.

The transfer of continuous paper by the paper feed tractor and the lateral movement of the nozzle pendulum are operations performed in synchronization.
That is, when the nozzle pendulum is swung to the leftmost end, the perforation of the continuous paper is near the tip of the nozzle pendulum, and when the nozzle pendulum is swung to the rightmost end, the next perforation of the continuous paper is still the nozzle pendulum. Must be near the tip. Such an operation is such that the paper feed tractor transfers the continuous paper at the perforation interval with respect to one operation from the left end to the right end of the nozzle pendulum or one operation from the right end to the left end of the nozzle pendulum. In addition, the perforation is moved so that the perforation is near the tip of the nozzle pendulum swinging to the left and right ends. In order to realize such a synchronized operation, one motor 1 in which the paper feed tractor and the nozzle pendulum are connected by a transmission mechanism 107 having a predetermined transmission ratio.
It is driven by 06. (See FIG. 4, FIG. 4 is a diagram schematically showing a configuration of a conventional folding delivery device).

[0004]

By the way, the perforation of the continuous paper and the distance between the perforations differ depending on the item. Therefore, it is necessary to change the transmission ratio in the transmission mechanism every time the manufactured item is changed, and conventionally, a gear dedicated to the item is prepared and gears are replaced. However,
According to such a method, it takes time and labor to switch the gears, gears of only the type of folding top and bottom size (perforation spacing) are required, and there are folding top and bottom sizes that cannot be supported due to the gear ratio. There is a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a folding delivery device capable of easily setting a synchronous operation according to a manufactured item, requiring no dedicated gear, and capable of supporting an arbitrary folding top and bottom size. To provide.

It

[0008]

The present invention will be described below based on the preferred embodiments. FIG. 1 is a diagram schematically showing a configuration of a folding delivery device of the present invention. In FIG. 1, 1 is a continuous paper, 2 is a paper feed tractor as a delivery means, 3 is a nozzle pendulum as a zigzag folding means, 4a and 4b are rattles, 5a and 5b are screws, and 6 is a paper feed tractor 2. A first drive motor, 7 is a first transmission mechanism, 8 is a second drive motor that drives the nozzle pendulum 3, and 9 is a second transmission mechanism.

The operation of the above configuration will be described.
The paper feed tractor 2 is a first composed of a speed reducer, a joint, etc.
It is connected to the first drive motor 6 via the transmission mechanism 7 and the paper feed tractor 2 transfers the continuous paper 1 in the direction of the arrow shown in FIG. In the case of FIG. 1, the paper feed tractor 2 has pins, and the pins are inserted into holes formed at both ends of the continuous paper 1 at equal intervals so that the continuous paper 1 can be transported without slipping. It The continuous paper 1 reaches the nozzle pendulum 3, passes through the inside of the nozzle of the nozzle pendulum 3, and is discharged onto the stage or the belt conveyor. At the time of discharging, the continuous paper 1 is shaken right and left by the nozzle pendulum 3 and zigzag-folded at the perforated portion to be folded. The postcards 4a and 4b and the screws 5a and 5b have a function of more reliably performing the zigzag folding. The perforations are formed in a direction perpendicular to the transport direction of the continuous paper 1.

In order to perform such zigzag folding, when the nozzle pendulum 3 is swung to the leftmost end as described above, the perforation of the continuous paper 1 is near the tip of the nozzle pendulum 3, and the nozzle pendulum is next. When 3 is swung to the rightmost end, the next perforation of the continuous paper 1 must also be near the tip of the nozzle pendulum 3. This kind of operation
With respect to one operation from the left end to the right end of the nozzle pendulum 3 or one operation (half cycle) from the right end to the left end of the nozzle pendulum 3, the paper feed tractor 2 moves the continuous paper 1 at perforation intervals. This is an operation in which the transfer is controlled and the transfer is controlled so that the perforations are near the tip of the nozzle pendulum swinging to the left and right ends.

In order to realize such a synchronized operation, the paper feed tractor 2 and the nozzle pendulum 3 are driven by a first drive motor 6 and a second drive motor 8, respectively. The second drive motor is controlled by a control mechanism that maintains a predetermined rotation speed ratio.
The control is not limited to the case where the continuous paper 1 is transported at a constant speed, and a predetermined rotation speed ratio is maintained when increasing the transport speed and decreasing the transport speed. Further, as described above, the perforation of the continuous paper 1 and the distance between the perforations differ depending on the item. Therefore, the rotation speed ratio of the first and second drive motors in the control mechanism can be changed every time the manufactured item is changed.

FIG. 2 is a block diagram showing the control mechanism of the first and second drive motors. In FIG. 2, 10 is a setting means for setting the perforation data of the continuous paper 1 which varies depending on the item, and 11 is a setting means, and 11 is a calculation of the rotational speed ratio based on the set data to operate the control means. Calculating means for generating data for
Control means for controlling the rotation of the second drive motor, 13 is a first tachometer for detecting the rotation of the first drive motor 6, and 14
Is a second tachometer for detecting the rotation of the second drive motor 8.

The setting means 10 is provided on the operation panel or the like of the folding delivery device 1 and sets the data of the perforations of the continuous paper 1 and the space between the perforations (fold top and bottom size). In addition, the zigzag folding of the continuous paper 1 formed by one half of the reciprocation of the nozzle pendulum 3 is set as one set, and the number of sets of one unit is set. One unit represents a packing unit, a work unit, or the like of the continuous paper 1 that is zigzag-folded. The data set by the setting means 10 is output to the computing means 11.

The calculation means 11 is specifically constituted by a device having a calculation function, such as a programmable sequence control device and a computer device for FA (Factory Automation). The calculation is performed based on the mathematical formula shown in the following Expression 1.

## EQU1 ## Ρout = (rotation speed ratio of output shaft of transmission mechanism) = (rotation speed of paper feed tractor) / (reciprocating speed of nozzle pendulum) = (perimeter of paper feed tractor) / (2 × (folding size) ))

As a matter of course, the actual rotation speed ratio of the first and second drive motors is a value divided by the deceleration rate by the first and second transmission mechanisms. That is, it is performed based on the mathematical formula shown by the following Expression 2.

## EQU00002 ## .PI.in = (rotational speed ratio of transmission mechanism input shaft) =. PI.out.times. (Deceleration rate of second transmission mechanism) / (deceleration rate of first transmission mechanism) = (rotational speed of first drive motor) ) / (Rotational speed of the second drive motor)

The data generated by the arithmetic unit 11 is
The control means 1 is the raw data (the above-mentioned Ρin) as the data whose format is converted to match the input format of the control means 12.
2 is output. The control means 12 controls the rotation speeds of the first and second drive motors based on the rotation speed ratio data and the operation speed command data described above. Specifically, the control means 12 includes, for example, one motor control unit for multi-axis control and two servo packs (driving power unit) for AC servo or DC servo. In multi-axis control (two-axis control in the present invention), the rotation angle, rotation speed, etc. of each axis are controlled according to predetermined regulations.
In the case of the present invention, the rotation speeds of the first and second drive motors change according to the operation speed command data, but control is performed so that the rotation speed ratio determined by the rotation speed ratio data is always held. .

Therefore, the control means 12 is fed back with the output signals of the first and second tachometers for detecting the rotations of the respective axes of the first and second drive motors. The output shaft of the first drive motor 6 is connected to the input shaft of the first transmission mechanism 7, and the output shaft of the first transmission mechanism 7 rotationally drives the paper feed tractor 2. The output shaft of the second drive motor 8 is connected to the input shaft of the second transmission mechanism 9, and the output shaft of the second transmission mechanism 9 reciprocally drives the paper feed nozzle pendulum 3.

In the above-described two-axis control, the linear interpolation of the two-axis motor is a function of controlling the work to move linearly at a set speed from an initial position to a set end position. In other words, this function is to control the ratio of each axis as described above. The setting of the end point position when this is applied to the folding delivery device will be described below. When folding continuous paper of folding top / bottom size a (inch) b (set), the nozzle pendulum is 360d
Since two sets are folded with an egg rotation (one reciprocation), the rotation amount of the nozzle pendulum is given by the following expression 3.

## EQU00003 ## (Nozzle pendulum rotation amount) = (b / 2) .times.360 (deg)

At this time, the paper feed tractor loads the paper axb.
From (inch) feeding, the rotation amount of the paper feed tractor is given by the following formula 4 when the circumference of the tractor is L.

## EQU00004 ## (Tractor rotation amount) = (a.times.b / L) .times.360 (deg) That is, this (nozzle pendulum rotation amount, tractor rotation amount) becomes the (X, Y) coordinates of the end point position. FIG. 3 is an explanatory diagram of a control operation in the folding delivery device of the present invention.
In FIG. 3, the X axis represents the nozzle pendulum rotation amount (1 reciprocation per rotation), and the Y axis represents the rotation amount of the paper feed tractor. The unit is degrees in both X and Y axes. In FIG. 3, regarding the above-mentioned end point position, the number of sets is b with the folding top / bottom size a1.
The end point position at 1 and the end point position at the folding top / bottom size a2 and the set number b2 are shown.

As described above, according to the present invention, it is possible to easily set the synchronous operation according to the manufactured item, and to cope with the change of the folding top and bottom size without the need for a dedicated gear. A folding delivery device is provided.
