2. Description of the Related Art FIG. 2 shows an example of a conventional printing method on the surface of a cable. Printing is being performed. The printing roller 2 has printing characters inscribed on the surface of the roller body. The print roller 2 uses the pulling force of the cable 1 for printing the print roller 2 to rotate the print roller 2 in the same direction as the pulling direction, thereby printing the contents of the print characters inscribed on the print roller surface on the cable surface. Switching of printing has been performed by manually replacing the printing roller.

[0003]

According to the prior art described above; according to the method of printing on the cable surface shown in FIG. 2, the more types of printing, the more types of printing rollers 2 are required.
The economic burden on the printing roller 2 increases. Also,
Since the printing roller 2 itself must be replaced by a manual operation when the print type is switched, it is necessary to secure personnel and perform the operation for switching. Since the printing roller 2 is made of metal, the length of the interval cannot be changed even if an attempt is made to change the interval for each print as shown in FIG.

According to the present invention, there is provided an automatic printing control method for a cable surface, in which a signal from a display capable of setting and displaying printing control and information is input to a computing unit. A printer that receives the output signal from the arithmetic unit prints it on the surface of the cable, a signal from an encoder that measures the interval of each printed cable, and a scale that measures the length of the printed cable. Is input to an arithmetic unit, and the arithmetic unit compares the set value of the display with the measured value of the encoder and the measuring instrument to control the printing press.

According to this means, the contents of printing are registered in the printing press, the conditions for printing on the display are set, and these are input to the computing device, while signals from the measuring instrument and the encoder are transmitted to the computing device. , The printing can be controlled. This is a method of comparing and calculating the set value of the display unit and the measured value by the measuring instrument and the encoder with a calculator, so if printing conditions are set before printing, adjustment of printing intervals and diversification of printing types And automatic switching becomes possible.

[0007] As the printing machine, an ink jet printer or a laser beam printer is preferably used. An abnormality detector for detecting an abnormality on the surface of the cable is provided, and by inputting a signal from the abnormality detector to a computing unit, it is possible to control whether or not the number of cables is measured by the display unit. it can. The display may include a counter for displaying a printing interval and a length of a cable to be printed, and a display only for displaying an identification number of a printing type.

According to the present invention, as a means different from the above method, a personal computer capable of inputting a program relating to printing control and information is used, and printing is performed on a cable surface by a printing machine which receives a signal from the personal computer. A signal from an encoder that measures the interval of each printed cable on a printed cable, and a signal from a measuring instrument that measures the length of the printed cable are input to the personal computer. A method of controlling the printing press by comparing and calculating values measured by an encoder and a measuring instrument can be provided.

[0009]

FIG. 1 shows a preferred embodiment of a method for controlling automatic printing of the cable surface according to the present invention.

As shown, this embodiment employs an ink jet printer 4 for printing on the surface of the cable 1,
A display 5 capable of displaying various information or outputting a signal by inputting a program, an arithmetic unit 6 for controlling each device and capable of inputting a program, and printed on the surface of the cable 1 Encoder 7 for measuring printing interval, abnormality detector 8 for detecting abnormality of cable, measuring instrument 9 for measuring length of printed cable
It is composed of

The encoder 7 and the measuring instrument 9 are fixedly arranged, and are installed so as to be in contact with the surface of the cable 1. The inkjet printer 4, the display 5, the encoder 7, the abnormality detector 8, and the measuring instrument 9 are connected to the calculator 6.

The contents to be printed on the ink jet printer 4 are input. By using the identification number, several types of print contents can be set.

The length of the printing interval, the length of the cable to be printed, the number of cables to be printed, and the identification number of the type of printing are input to the display 5 in the order of printing. These settings can be set in several patterns by using setting numbers.

The length of the printing interval is measured by the encoder 7,
The measurement result is calculated by the calculator 6. The computing unit 6 calculates the length of the printing interval set by the display 5 and the length of the printing interval measured by the encoder 7. When the condition of “the length of the printing interval measured by the encoder 7 ≧ the length of the printing interval set by the display 5” is reached, the arithmetic unit 6 outputs a signal of the selected identification number to the inkjet printer 4, The printer 4 prints the identification number on the cable 1.

The length of the printed cable is measured by the measuring instrument 9, and the result is calculated by the calculator 6. The set length of the printing interval set on the display unit 5 and the encoder 7 to the arithmetic unit 6
The arithmetic unit 6 calculates the length of the printing interval input to. When the condition of “the length of the printed cable measured by the measuring instrument 9 ≧ the set length of the printed cable set by the display unit 5” is reached, the printing of the cable is completed.

Further, an abnormality on the cable is measured by the abnormality detector 8, and a defective cable and a normal cable are discriminated. When an abnormality on the cable is detected, the display 5
Is not counted. If no abnormality is detected on the cable, it is identified as a normal product, and the number of cables is counted.

“Number of printed cables ≧ number of cables set by indicator 5” and “length of printed cable measured by measuring instrument 9 ≧ set length of printed cable set by indicator 5” When the condition (1) is satisfied, the setting number is automatically switched to the next setting number, and the printing is automatically switched.

As in the present embodiment, the setting of printing on the cable surface is performed by using the display unit 5 capable of inputting a program, so that the operation method is not complicated, and the setting of printing on the cable surface is easily performed. be able to.

This embodiment is particularly effective when the types of printing are diversified and printing needs to be frequently switched.

It is also possible to output information using an alarm when printing is switched, when an abnormality is detected on the cable surface by the abnormality detector, or when printing is completed.

Further, as an application of the present invention, it is also possible to perform spiral printing by printing a cable to be printed while rotating the cable itself in the traveling direction. In addition, it is also possible to perform printing on products other than the cable by using a photodetector instead of the encoder and the measuring instrument.
