DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for detecting a printed book in a collating machine.

[0002]

2. Description of the Related Art A conventional bookbinding detecting device of this kind of collating machine is composed of:
The mode of the detection data in the sensor is set in a stepwise manner in advance, and the mode is appropriately selected and detected in consideration of the paper quality, print type, figure density and other conditions of the printing book.
That is, Japanese Utility Model Laid-Open No. 63-41063 discloses a collating machine.
To use a sensor to detect a printed book
Have been. In Japanese Utility Model Application Laid-Open No. 63-90659,

Problems to be Solved by the Invention
No. 063 discloses the detection data and the set value of the setting device.
It is disclosed to make a comparison, but it is detected by a shift in the detection position
Data is changing and floating, so even the correct book is bad
Signals may be sent out, and sudden stoppage may reduce collation efficiency.
It is the one that lowers it. In addition, the actual opening 63-90
No. 659 is not good in comparison with the command data.
Signaling is the same, but depending on how bad signals are picked up.
Often stop the collating machine, and as described above, collation efficiency
Is significantly reduced.

[0004] In other words, even for the same printing book, for example, the folding line position may be slightly displaced, and even on the pay-out table, there is a deviation of several mm before and after. The type status for the sensor on this surface changes greatly,
There is a big difference in the data. Therefore, if the strict mode of the conventional detection device disclosed is selected, even if it is a normal book, an error is displayed, the collating machine is frequently stopped, and the production capacity is seriously affected. is there. On the other hand, if a loose mode is selected, an improper print book cannot be rejected, and a detection error occurs. The present invention eliminates such a conventional drawback, sets a detection mode suitable for the condition of a printed book, and aims to eliminate detection malfunction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings, which are embodiments of the present invention. Reference numeral 1 denotes a sensor. The sensor 1 for detecting the sensor 2 includes an LED light emitter 4 and a light receiving element 5.

The light receiving element 5 receives the reflected light from the printing book 2, and inputs the current to the multiplexer 7 via the amplifier 6. Here, the plurality of light receiving elements 5 are sequentially switched to take out the light receiving current. Amplified by amplifier 8 and A /
The analog signal is converted into a digital signal by the D converter 9 and
It is configured to input to the PU central processing unit 10.

The printing book 2 is detected each time it is fed. The timing signal and other signals are sent to the CPU central processing unit 1
In addition, the CPU central processing unit 10 outputs a machine stop output for stopping the delivery of a print book and other necessary outputs from the CPU central processing unit 10. The CPU central processing unit 10 is configured and programmed to be controlled by the keys shown in FIG. 3 and to output a display. That is, under the required setting conditions, the same printing book 2 is detected, different printing sheets are detected, and the machine is stopped.

Next, the method and apparatus of the present invention will be described with reference to the flowchart of FIG.

When the power is turned on and a timing signal is input from the machine, a measurement signal is output, and data measurement starts.
Teaching starts. That is, the measurement data of the sensor 1 is calculated, and the measurement value bar graph 11
And store it. And it is counted up reaches the set measurement number of times N, the tolerance data based on the deviation of the total measurement data automatically calculated, and automatically set the allowable value by adding it to the basic example + alpha to which the lower Is displayed on the allowable value bar graph 12, and the teaching ends. This automatic setting allowable value can be finely adjusted manually.

Next, the actual operation of the machine is started, and the data measurement of the printing book 2 by the sensor 1 is performed at every feeding, the present data is compared with the previous data, and deviation data is calculated. When the deviation data is equal to the allowable value and when the deviation data is small, the internal data is updated, the allowable value data is updated, and the delivery of the printing book 2 is continued. When the deviation data is larger than the permissible value, an error signal is issued, the error signal is counted, and when the set count is reached,
It counts up, turns on the stop signal light 13, and stops the machine. 14 is a restart switch.

For comparing the deviation data with the allowable value, three types of modes can be selected.
In this case, the B mode has twice the tolerance and the C mode has four times the tolerance.

The number of times the error signal is counted up is:
This is because if the machine is stopped by one error signal, it is affected by the measurement error, and if the machine is normal, the machine is stopped, and the production capacity of the entire machine may be significantly impaired.

[0019]

As described above, according to the present invention, as to how to set the allowable value data, the printing data actually used in the work is directly output, for example, by performing the necessary number of samplings, and the measurement data is obtained. Because the tolerance is automatically set based on the deviation data of the tolerance data, compare the preset data as before.
Unlike what you use, there is no mistake,
The measured data can be displayed on a bar graph and displayed directly to check the measured data by visual confirmation.The status of the printed book can be directly compared with the measured data. Fine adjustments can be made, and even a general operator can easily and automatically set an allowable value.

Further, since the present invention is provided at each feeding portion of each printing book and provided with a stop light and a restart switch of the machine, it is possible to input while observing the printing book. It is clear at a glance even if there is an abnormality, and the machine can be quickly restarted even after it has stopped.

Therefore, it is possible to greatly improve the discrimination of the difference between the printed books and the paper misalignment in the collating machine.
