Sometimes, a new code can be attached to the winding core by inputting information corresponding to a new lot or type from the input means.

Therefore, the code assigning device can flexibly cope with small lot production of various kinds.

As the input means, for example, a touch panel input device for inputting by pressing the touch panel with a finger,
Examples include a numeric keypad and a keyboard of a desktop computer, but the touch panel, numeric keypad, and keyboard are not particularly limited as long as they can input letters, numbers, and symbols.

In the invention according to claim 7, the code is:

In the code assigning device, the information input from the input means is converted by the digital signal converting means into a digital input signal consisting of an array of 1s and 0s and output to the code forming means. Then, the code forming means converts the code into an optically readable code.
Then, the arrangement of the light reflection section and the light absorption section is determined by making the light reflection section in the optical reading type code correspond to 1 of the digital input signal and the light absorption section to 0 in the digital input signal. can do.

The optical reading type code is formed as an assembly of unit arrays which is an array consisting of one light reflection section and one light absorption section, and one light reflection section of the unit array is formed. Then, a first unit array consisting of one adjacent light absorption section is made to correspond to 1 of the digital input signal, and a second unit array consisting of one light absorption section and one adjacent light reflection section thereafter. A unit array may correspond to 0 of the digital input signal. Where "before",

It has the appearance of a single colored strip on its side.

Therefore, the tubular body on which the infrared reading code is formed has little discomfort in terms of appearance.

The infrared absorbing section and the infrared reflecting section can be formed by printing using an infrared absorbing ink and an infrared non-absorbing ink, respectively.

In the infrared readable code, one of the infrared absorption section and the infrared reflection section is printed on the cylindrical body, and then the infrared absorption section or the infrared reflection section is not printed, The other of the infrared absorption section and the infrared reflection section can be printed and formed.

It can be prepared by blending various infrared absorbers. Further, as the infrared non-absorptive ink, an oil-based or water-based printing ink which has the same color as the infrared absorbent but does not contain the infrared absorbent can be used.

In addition, since many of the infrared absorbents contained in the infrared absorbing ink are black, it is difficult to visually identify the infrared absorbing section and the infrared reflecting section, and the like.

The present invention relates to a code applying device including a base forming means formed over the base forming means and an infrared absorbing code forming means forming an infrared absorbing section in the infrared reading type code on the base formed by the base forming means.

The present invention relates to a code assigning device including a comparison / determination unit that determines that a shaped article is defective.

The code assigning device converts the code added by the code forming means and the information to be shown by the code into digital signals each having an array of 1s and 0s, and compares them. The quality of the tubular body can be judged efficiently and with high reliability.

In the code applying device, when the code provided by the code forming means is an infrared readable code, the code reading means emits light such as a light emitting diode for irradiating the infrared readable code with infrared rays. By receiving the element and infrared rays reflected from the code,

The present invention relates to a code assigning device that includes a section array signal generator and a digital code signal generator that generates the digital code signal based on the section array signal generated by the section array signal generator.

In the section array signal generating device provided in the code assigning device, for example, when the analog signal output from the optical code reading device has a sine wave-shaped analog signal, the wave height is increased when the intensity of the analog signal exceeds a certain value. When it is 100 and is lower than the above value, the section array signal can be generated by converting into a rectangular wave having a wave height of 0.

In the digital code signal generator, for example, the section array signal generated by the section array signal generator, that is, the section having a wave height of 100 in a rectangular wave is a section having a high infrared reflection intensity, that is, an infrared reflection section. Correspondingly, the section where the wave height in the rectangular wave is 0 is
It is determined that it corresponds to a section where the infrared reflection intensity is weak, that is, an infrared absorption section.

This is an example of the Manchester coding method, in which "0" is given to a section in which a section with a wave height of 100 is adjacent to a section with a wave height of 0, and a section with a wave height of 0 has a wave height of 100. The rectangular wave is converted into the digital code signal by a method of adding "1" to a section in which the section is adjacent.

As shown in FIG. 20, in step 202, according to the instruction displayed on the touch panel 3A, the recording sheet information regarding the information recording sheet wound around the paper core C is input from the touch panel 3A by numbers or alphabets.

The recording paper information input from the touch panel 3A is transferred to the central control computer 1 in step 204.
In step 206, in the central control computer 1A, for example, a 24-bit digital input signal “00000000001010101111100” is transmitted.
Converted to 1 ”.

Next, in step 206, in the central control computer 1A, the digital input signal is converted into information code print data indicating the arrangement of the infrared reflection section and the infrared absorption section according to a predetermined rule, and the information code is converted. A command to print the infrared absorption section according to the print data is output to the base printer controller 8B and the information code printer controller 12B.

FIG. 21 shows an example of rules for converting the digital input signal into information code print data and information code print data obtained by converting the digital input signal.

In the central control computer 1A, for example, the Manchester coding system, that is, FIG.
1, as shown in (A), a. Replacing "0" of the digital input signal with a first unit array in which an infrared absorption section is located after an infrared reflection section; b. Regarding "1" of the digital input signal, the digital input signal "000000000000101010111110" according to the code conversion method in which the infrared absorption section is followed by the second unit array in which the infrared reflection section is located.
The first unit array and the second unit array are allocated to "0" and "1" in "01". Then, a start mark having three consecutive infrared absorption sections is provided at the tip of the array of the first unit array and the second unit array. The start mark is made up of a total of five sections including the three infrared absorption sections and the two infrared reflection sections adjacent before and after the three infrared absorption sections, and indicates the start point of the information code. In this way, the digital input signal is converted into the information code print data shown in FIG. 21 (B). In FIGS. 21A and 21B, a white rectangle indicates a section where an infrared reflection section should be provided, and a black rectangle indicates a section where an infrared absorption section should be provided.

The central control computer 1A issues a command to the end face of the paper tube C to print an information code in the counterclockwise direction according to the information code print data, in the turret 2 of the code printing apparatus 1000 and the paper tube mounting apparatus. 6, the base printer controller 8B, and the information code printer controller 12B.

The paper core mounting device 6 mounts the paper core C in the paper core mounting cylinder 38 of the paper core holding device 4 in response to the command from the central control computer 1A.

When the paper tube C is attached to the paper tube holding device 4,
The servomotor 22 rotates the turret 2 by 1/8 in the clockwise direction in FIGS. 1 and 2 in response to a command from the central control computer 1A.

Turret 2 is 1/8 in the clockwise direction.
It stops when it rotates. At this time, the paper core holding device 4 in which the paper core C is mounted by the paper core mounting device 6 is
Move to a position relative to. Base printer controller 8B
Receives the command from the central control computer 1A,
A control command is output to the base printer 8. Base printer 8
Receives the control command from the base printer controller 8B and prints the base on the end surface of the paper tube C.

After printing the base on the end surface of the paper tube C, the servomotor 22 moves the turret 2 once again in the clockwise direction.
/ 8 turn. By rotating the turret 2 by 1/8 after the base printing, the paper tube C on which the base is printed by the base printer 8 moves to a position facing the hot plate 10. Paper tube C
The end surface on which the base is formed is heated by the heat from the heating plate 10 to dry the infrared non-absorptive ink applied by the base printer 8. The temperature data of the hot plate 10 is input to the central control computer 1A from the temperature control device that controls the hot plate 10.

After the base was dried, the turret 2 was 1 /
Paper core C that has been rotated eight times and the background has been printed by the background printer 8.
Moves to a position facing the information code printer 12.

Here, in the information code print data, as described above, the white or black rectangle 2
One corresponds to one bit of the digital information. Since the digital input signal is 24-bit information as described above, the number of rectangles corresponding to the digital input signal in the information code print data is 2 (pieces).
× 24 (bits) = 48 (pieces). Then, as described above, since the start mark composed of the five rectangles is provided at the beginning of the information code print data, the number of the rectangles of the entire information code print data is
There are 48 + 5 = 53 (pieces).

Therefore, the rectangle in the information code print data corresponds to one of fan-shaped sections obtained by equally dividing the end surface of the paper tube C on which the base is formed into 53 in the circumferential direction.

Therefore, the central control computer 1A rotates the paper tube mounting cylinder 38 of the paper tube holding device 4 located at a position facing the information code printer 12, and at the same time, stores the information code print data shown in FIG. An instruction to print the infrared reading section with the infrared absorbing ink in the section corresponding to the black rectangle is output to the information code printer controller 12B, and the information code printer controller 12B outputs the information code according to the instruction. The printer 12 is controlled.

The information code printer 12 is controlled by the information code printer controller 12B to apply the infrared absorbing ink to the end surface of the paper tube C to form a bar code-like information code. FIG. 22 shows the information code printed on the paper tube C in this manner.

When the information code is formed by the information code printer 12, the turret 2 further rotates 1/8, and the paper tube C on which the information code is printed by the information code printer 12 is
The information code is dried by moving to a position facing the heating plate 14 and being heated by the heating plate 14. The temperature data of the hot plate 14 is also input to the central control computer 1A from the temperature control device that controls the hot plate 14.

C-2 When the information code is dried by the heat from the information code reading / comparison / judgment heating plate 14, the turret 2 is further rotated 1/8, and the paper tube C on which the information code is formed is , To a position opposite to the code reading device 16.

In the code reading device 16, the information code printed by the information code printer 12 is read, the result is converted into a digital code signal in the inspection computer 1B according to the following procedure, and the touch panel 3A is operated.
Compare with the recording paper information input from.

The photo interrupter 16A in the code reading device 16 emits infrared rays toward the information code shown in FIG. 22 formed on the end face of the paper tube C, receives the infrared rays reflected by the information code, and receives the received infrared rays. Generates a current output according to the strength of.

As shown in FIG. 23, the current output output from the photo interrupter 16A is converted into a voltage signal by the analog signal processing circuit 16B, and the 16-bit A / D conversion circuit 16C outputs 2 ¹⁶ steps, that is, 65596. It is converted into a digitized output having a stepwise output intensity. In addition,
The signal phases are the same from the photo interrupter 16A to the A / D conversion circuit 16C.

The current output from the photo interrupter 16A is shown by the curve a in FIG. A / D
The digitized output output from the conversion circuit 16C is also shown by the curve a.

The digitized output is transmitted to the inspection computer 1B. Then, as a reference for matching the bit of the digitized output, that is, the bit of the information code read by the code reading device 16 with the bit of the rectangular wave output described later, a rotary encoder (not shown) that is interlocked with the drive motor 34. The clock pulse generated in 1) is also input to the inspection computer 1B when reading the information code.

The inspection computer 1B determines, for each bit in the information code, whether the output intensity of the digitized output is equal to or greater than a certain reference value x. Then, when the output intensity of the digitized output is equal to or greater than the reference value x at the 1st bit, a signal having a wave height of 100% is output for the bit. Then, in the other bits, when the output intensity of the digitized output is less than the reference value x, a signal with a wave height of 0% is output for the bit. In this way, the digitized output is converted into a rectangular wave. The rectangular wave obtained by converting the digitized output in this manner is shown by a curve b in FIG.

In the rectangular wave b, the portion having a wave height of 100% corresponds to the infrared reflection section in the information code,
Since the wave height 0% portion corresponds to the infrared absorption section in the information code, the inspection computer 1B associates the wave height 100% portion in the rectangular wave b with the white rectangle indicating the infrared reflection section, and the rectangular shape. The rectangular wave b is converted into information code print data by making the portion of the wave b having a wave height of 0% correspond to the black-painted rectangle showing the infrared reflection section. 25A shows the rectangular wave b before conversion, and FIG. 25 shows the information code print data after conversion.
(B) in FIG.

As shown in FIG. 25 (A), the rectangular wave b has one section with a wave height of 100%, three sections with a wave height of 0% that follow, and a wave height 1 that follows the section with a wave height of 0%.
Start with one segment of 00%. The section is shown in FIG.
(B) in the converted information code print data, it corresponds to the first five sections consisting of one white rectangle, three black rectangles and one white rectangle that follow. . Here, it is only the start mark that three or more black-painted rectangles continue, and in the section from 1 bit to 24 bits indicating the recording paper information, both the white-painted rectangle and the black-painted rectangle are 3 No more than one item in a row.

Therefore, the inspection computer 1B recognizes the first five sections as start marks and determines that the section indicating the recording paper information starts from the section following the five sections.

Further, the inspection computer 1B corresponds the information code print data obtained by converting the rectangular wave to the unit array in which the black-painted rectangle is located next to the white-painted rectangle, as indicated by 302 in FIG. The information code print data is set by the Manchester coding method in which the recording paper information bit is set to "0" and the recording paper information bit corresponding to the unit array in which the black rectangle is located next to the white rectangle is set to "1". Is converted into a digital code signal composed of an array of 1s and 0s. For example, the digital code signal obtained by converting the information code print data shown in (B) of FIG. 25 according to the procedure 302 is “00000000001010101.
1111001 ".

The inspection computer 1B outputs the digital code signal as shown in step 304 in FIG.
The recorded information input from the touch panel 3A is compared with the converted digital input signal. If the two match completely, the paper tube C is determined to be a non-defective product, and the paper tube C is determined to be a non-defective product 118 to the central control computer 1A.
And outputs a command to control the paper tube sorting device 20 so that the paper core sorting device 20 is guided. On the other hand, if the digital code signal has a portion that does not match the digital input signal,
The paper core C is determined to be a defective product, and a command is issued to the central control computer 1A to control the paper core sorting device 20 so as to guide the paper core C to the defective product chute 120.

Upon receiving the command from the central control computer 1A, the paper tube sorting apparatus 20 guides the paper tube C to the good product chute 118 or drops it into the defective product collection box 130.

The code printing apparatus 1000 according to the first embodiment

8 and the paper tube sorting device 20 are arranged around the turret 2, the entire structure can be made compact and easy to install in a line or the like.

Further, as the information code, an infrared reading type code is possible, so that the information code can be read in a non-contact manner, and the quality judgment can be made efficiently.

Since both the infrared reflection section and the infrared absorption section of the information code can be formed in a dark color such as black, the end surface of the paper tube C on which the information code is printed by the code printing device 1000 is electrophotographic. Even if it is copied, only the black ring is shown, and it is almost impossible to copy or tamper the information code by an inexpensive means.

Further, since the recording paper information input from the touch panel 3A and the information read from the information code are both converted into digital signals and compared, the comparison between the two is performed by the existing desktop computer. Can be performed easily and surely.

Further, since the Manchester code system is adopted for the production and reading of the information code, three or more infrared reflection sections and infrared absorption sections do not continue.

Therefore, the risk of erroneous reading is extremely low, and the code reader 1 included in the code printing apparatus 1000 is provided by providing three or more infrared reflection sections or infrared absorption sections in the information code.
The start point of the information code can be easily read by the user.
