Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a collating device for strip slips to control the traveling speed while controlling the tension of the belt-like document.

[0002]

2. Description of the Related Art For example, there is a slip 50 of the type shown in FIG. In this slip 50, a single leaf slip T provided with positioning holes h at both edges is superimposed, and is glued in a linear or dot shape inside one edge of the slip T. A slip manufacturing apparatus (not shown) is used to mass-produce the slip 50 having such a configuration, and a part of the slip manufacturing apparatus is constituted by a collating apparatus.

The collating apparatus has a pin belt on which pins are implanted at a constant pitch, and the holes h of the form 50 are inserted into the pins of the pin belt to position each form.
Collation that does not cause displacement of each slip is performed. However, the material of the slip (web, strip-shaped slip) may expand and contract due to humidity or the like, and the pitch of the holes h may fluctuate. Due to this variation, the hole h of the slip 50 may not be properly inserted into the pins of the pin belt, which may hinder the manufacture of the slip.

Therefore, the applicant of the present invention has proposed a "web collating method and collating apparatus" which ensures that the holes h are inserted through the pins of the pin belt even if the pitch of the holes h of the slip fluctuates.
(Japanese Patent Application No. 02-333577).

FIG. 5 shows a main part of the collating apparatus. That is,
Pins 51b are implanted at a constant pitch on the outer peripheral surface of the pin belt 51 driven by the driving roller 51a. Immediately above the pin belt 51, a guide roller 52 for guiding a strip-shaped slip 50A, which is a material of each slip 50, onto the pin belt 51 is disposed. Above the guide roller 52, a slack that causes the strip-shaped slip 50A to loosen is formed. A generator T is provided.

The slack generating device T includes a rotatable roller 53 disposed above the guide roller 52, and a pair of drive rollers 54, 55 disposed at a predetermined distance from the roller 53. Consists of After passing through the driving rollers 54 and 55, the belt-shaped slip 50 </ b> A hangs down in a U-shape, and is guided to the pin belt 51 via the roller 53 and the guide roller 52. The roller 53 is located above the pin belt 51.
A belt-shaped slip 50A suspended in a U-shape between the driving roller 54 and the roller 53 is provided below the intermediate portion of the driving roller 54 and the driving roller 54.
An ultrasonic displacement sensor 56 for detecting the tip of the sensor is provided. The drive roller 54 is driven to rotate by a servomotor 58 whose rotation is controlled by a controller 57. The fuzzy inference data generated by the fuzzy inference unit 59 having the fuzzy table shown in FIG. 6 is integrated by the integrator 60 and then supplied to the servo motor 58 via the controller 57 as described above.

With this configuration, the belt-shaped slip is set to free tension, and furthermore, the driving and supply of the strip-shaped slip are performed by fuzzy control. Can be inserted.

[0008]

However, for example, as shown in FIG. 7 (A), the band form 50A may include a connecting portion 50B connecting the front and rear band forms at the paper maker. Further, in the change of the winding by the collating device, the old and new windings are changed by the paper feeding unit, so that a connecting portion as shown in FIG. When the joint 50B is conveyed to a position facing the displacement sensor 56, as shown in FIG. 7 (B), in order to realize a no-tension state, the U-shape is properly formed by the free slack portion. However, it may deviate from the normal control range ± y, and as a result, the original fine control may not be performed. In other words, the traveling control device for the band-shaped slip (band-shaped sheet) of the conventional collating device can cope with small external noise such as factory noise, but sufficiently cope with "extreme disturbance" such as a joint portion. Could not.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a collating apparatus for a band-shaped slip which can surely run the band-shaped slip against an extreme disturbance. Aim.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. Note that the same reference numerals are given to the already described portions, and redundant description is omitted.

As shown in FIG. 1, a signal detected by the displacement sensor 56 is input via a voltage converter 1 to one input terminal of a fuzzy controller 2 described later. On the other hand, the speed of the pin belt 51 is detected by the speed sensor 3, and the detected data is input to the other input terminal of the fuzzy controller 2 via the voltage converter 4 and the first data is input via the A / D converter 8. The data is input to one input terminal of the adder 6 as drive data.

The fuzzy controller 2 has a fuzzy table shown in FIG. 2, and performs fuzzy inference according to the slack amount of the belt-shaped sheet 50A detected by the displacement sensor 56 and the speed of the pin belt 51 detected by the speed sensor 3. The result of the fuzzy inference by the fuzzy controller 2 is input to the other input terminal of the adder 6 as the second drive data via the A / D converter 5, and the pin belt speed signal (first drive data) and the fuzzy inference result (Second drive data) is added (see FIG. 3). The output of the adder 6 is D
The signal is input to the servo motor 58 via the / A converter 9, and the drive roller 54 is rotationally driven.

Next, the operation of the control system including the fuzzy controller 2 and the adder 6 will be described. As shown in FIG. 1, a belt-shaped slip 50A is provided between the driving roller 54 and the roller 53.
, And the belt-shaped slip 50A is hung in a U-shape. The amount of sag (slack amount) at which the band form is smoothly inserted into the pin belt is known in advance according to the type of the band form, and as shown in FIG. Is “ZR”. In the increasing direction of the slack amount, “in the case of small” is “PS”, “in the middle” is “PM”, and “in the case of large” is “PL”. Conversely, if the amount of slack decreases in the decreasing direction, “if it is small” is “NS”, and “if it is medium” is “N”.
M ”, and“ large ”is“ NL ”.

Also, the case where the pin belt speed is almost zero is "zr", the case where the pin belt speed is low is "ps", and the case where the pin belt speed is medium is "pm".
“Large” is “pl”.

[0017] For example, "The band-shaped slip is slightly slack (P
In S), when the pin belt speed is low (ps), the output of the fuzzy controller 2 (second drive data) is slightly reduced (NS). By doing so, the driving roller 54
Since the control amount of the supply of the band-shaped slip is changed according to the speed, the slack is secured at a fixed position, and the hole of the band-shaped slip is securely inserted into the pin of the pin belt.

Further, if the slack of the belt-shaped slip is in the middle (ZR) and the pin belt speed is considerably high (p
l), the output of the fuzzy controller 2 is the standard speed (Z
R) ". In this case, although the speed is high, the slack is at an appropriate position, so that the U-shaped free tension can be secured without any particular control.

In the case of "extreme disturbance" as shown in FIG. 7B, even if the output of the displacement sensor 56 becomes zero, as shown in FIG. Since the component of the first drive data remains, the drive roller 54 is sufficiently driven. Therefore, the collating device does not stop.

When the above-described control is performed, as shown in FIG. 1 , there is a fuzzy control width with respect to the pin belt speed, so that the width for controlling the rotation of the drive roller 54 becomes large. Since the simple addition of the first drive data and the second drive data is performed each time, the influence of the extreme disturbance can be ignored. Therefore, control that is not affected by disturbance can be performed. Further, since the motor is controlled by detecting only the slack amount and the pin belt speed, fine adjustment is not required when the winding diameter, paper thickness, paper type, etc. of the belt-shaped sheet are changed.

Hereinafter, the band-shaped slip inserted into the pin is conveyed to the pin belt and sent downstream, where the folded slip 5
0 is completed. In this embodiment, the case of the collating apparatus has been described. However, the present invention is also applicable to a case where a sheet-like material must be supplied in a state close to no tension, such as a printing machine that handles a material having large expansion and contraction. it can.

[0022]

As described above, according to the present invention, when the motor is driven to rotate, the second driving data based on the pin belt speed and the slack amount are added to the first drive data based on the pin belt speed. Since the driving data is added to generate data for finally determining the rotation speed of the motor, even if the slack amount cannot be detected (FIG. 7).
(State of (B)) The motor can be rotationally driven based on the first drive data. Therefore, an appropriate amount in accordance with the type of belt-like documents
The belt-shaped slip is transported with a pin belt while giving the slack
Of course, but also in extreme disturbances

However, the first drive data can be output, so collating
Collation work can be continued without stopping
