DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a medicine packaging apparatus to which an embodiment of a paper wrapping paper tube according to the present invention is attached, and FIG. 2 is an enlarged perspective view of a main part showing the vicinity of a paper tube drum in FIG. It is.

In the medicine packaging apparatus shown in FIG. 1, a packaging paper 10 wound around a substantially cylindrical paper tube 9 is inserted into a substantially cylindrical hollow portion 10a provided at a substantially central portion of a packaging paper 10, A paper tube drum 7 rotatable to discharge the wrapping paper 10 and a brake plate 8 as a wrapping paper control means for controlling the speed at which the wrapping paper 10 is discharged.
And a roller 6 for leading the packaging paper 10 to the hopper 1.
And a hopper 1 as a medicine feeding means for feeding a medicine into the packaging paper 10, a heater 2 as a heat welding means (thermocompression bonding means), and an operation panel (not shown). As the packaging paper, one obtained by applying a synthetic resin such as polyethylene on one surface such as glassine paper or cellophane is used. In the medicine packaging apparatus, the heater 2 draws in the wrapping paper 10, whereby the paper tube drum 7 rotates to release the wrapping paper 10 from the wound state. That is, the paper tube drum 7 has
No drive device is provided for rotating the paper tube drum 7 itself. It should be noted that the paper tube drum 7 may be provided with a known paper break detection pin. This paper break detection pin is
The wrapping paper 10 wound around 9 is mounted on the paper core drum 7, and the breakage of the wrapping paper 10 can be detected.

On one side of the wrapping paper 10, that is, on the right side in FIGS. 1 and 2, the wrapping material such as the material and thickness of the wrapping paper or the temperature which should be appropriately set for welding. Symbol 11 as an example of an identifier indicating paper information (in FIG. 2,
(Represented by a combination of lowercase alphabets) is printed.
For example, a fluorescent paint which emits light and becomes visible only when irradiated with near ultraviolet rays of about 00 to 400 nm is used.

As shown in FIG. 1, the medicine packaging apparatus irradiates near ultraviolet rays to irradiate the side surface of the packaging paper 10 on which the symbol 11 is printed. 5 and an image sensor 4 as reading means for receiving the symbol 11 emitted by irradiating the black light 5 with near-ultraviolet light and reading the symbol 11 are provided close to the packaging paper 10. As means for irradiating near ultraviolet rays,
A xenon lamp with a filter, an ultraviolet LED, or the like can also be used.

The medicine packaging apparatus is provided with a microcomputer (not shown in FIG. 1), and stores therein packaging information of a packaging paper preferably used in the present medicine packaging apparatus. . Then, data on the symbol 11 read by the image sensor 4 is transmitted to the microcomputer. FIG. 3 is a block diagram showing the connection relationship of the microcomputer 12, and the microcomputer 12 will be described below with reference to FIG. First, a heater 12 is connected to the microcomputer 12 as shown in FIG.
The appropriate temperature of the heater 2 is stored for each piece of packaging paper information, and the temperature of the heater 2 is set in accordance with the symbol 11 read by the image sensor 4.

Second, the microcomputer 12 is connected to the brake plate 8 as shown in FIG. 3, and feeds the paper when the wrapping paper 10 is discharged from the paper tube drum 7 and drawn into the heater 2. Is preset and stored as a predetermined speed. Therefore, the speed at which the packaging paper 10 is pulled in by the heater is substantially equal to the paper feed speed. Then, the microcomputer 12 detects the reading speed (described later) of the symbol 11 input from the image sensor 4 by the microcomputer 12, and the paper feeding speed becomes the predetermined speed, and the tension of the packaging paper 10 is kept constant. So that
The strength of the pressing force of the brake plate 8 against the wrapper 10 is controlled. That is, in the present medicine packaging apparatus, since the packaging paper 10 is fed by the heater 2 pulling in the packaging paper 10, the remaining amount of the packaging paper 10 is reduced, and the weight applied to the paper tube drum 7 is reduced. When the pressure becomes lighter, the tension tends to decrease and the paper feed tends to be faster. Therefore, the control of the paper feed speed can be achieved by controlling the strength of the pressing force of the brake plate 8.

A method for packaging a medicine by the medicine packaging apparatus thus constructed will be described below. First, the paper tube drum 7 around which the wrapping paper 10 is wound is mounted at a predetermined position, and the wrapping paper 10 is mounted to the position of the roller 6. Then, the switches of the black light 5 and the image sensor 4 are turned on by a switch or the like attached to an operation panel or the like provided to be operable by the user.

The image sensor 4 is set so as to always receive an image. The image sensor 4 reads the symbol 11 on the packaging paper 10 and transmits the data to the microcomputer 12. The microcomputer 12 identifies the packaging paper information represented by the symbol 11 read by the image sensor 4 and, if different from the packaging paper information stored in the microcomputer 12 in advance, the microcomputer 12
Generates a display signal to display an error on a display device (not shown) as alarm means attached to an operation panel or the like, and then stops the operation of the medicine packaging device.

If the symbol 11 read by the image sensor 4 matches the one stored in the microcomputer 12, the paper feed speed is detected next. That is, the microcomputer 12 has a reading speed at which the symbol 11 is read, in other words, the microcomputer 12
The interval (timing) at which the data of symbol 11 is transmitted to 12,
Is detected in the microcomputer 12, and it is detected whether or not the detected reading speed is within a predetermined speed range.
That is, as shown in FIGS. 2, 4 and 5, a character or bar code is printed on one side of the packaging paper 10 in a diameter direction, and the characters are closer to each other on the outer peripheral side of the packaging paper 10. Alternatively, the arrangement is such that the intervals between barcodes are widened. Here, each set of barcodes is printed in such a manner that the thick line, the thin line, and the blank portion constituting the set are parallel to each other and can be read by an ordinary barcode reader. Have been. Therefore, the length of the space between characters or between barcodes differs depending on whether the position where the character or the like is printed is closer to the outer periphery or closer to the inner periphery. Therefore, by detecting the length of the interval, the speed of the packaging paper 10 can be indirectly detected. That is, the microcomputer 12 plays a role as speed detecting means for detecting the reading speed at which the image sensor 4 reads the symbol 11.

Here, the control of the medicine packaging apparatus by the microcomputer 12 after the reading speed has changed and it has been detected whether or not the reading speed is the predetermined speed will be described. First, when the reading speed at which the symbol 11 is read exceeds the predetermined speed range, for example, when the reading speed is high, the pressing of the brake plate 8 against the packaging paper 10 is performed so that the reading speed is within the predetermined speed range. If the pressure is adjusted so as not to exceed the predetermined speed range, the packaging paper 10 is discharged at the same speed. If the reading speed is lower than the predetermined speed, the pressing force of the brake plate 8 is adjusted to be weakened, and the separating paper 10 is discharged.

Further, when the reading speed exceeds the predetermined speed range, the microcomputer 12 sets the reading speed to:
The remaining amount of the wrapping paper is calculated from the required time from the start of the discharge of the wrapping paper. Then, when the reading speed exceeds a predetermined speed range and exceeds a predetermined time, the remaining amount of the packaging paper is displayed in several stages separately, and the remaining amount is used to continue the packaging welding. When it becomes insufficient, an error is displayed on the display device (not shown). In order to detect the remaining amount, the position where the identifier is provided does not cover a position corresponding to a predetermined number of turns from the start of winding of the wrapping paper. When the number of turns reaches the predetermined amount (when the identifier is no longer detected), it can be confirmed that there is no remaining amount. As still another means, a specific identifier may be set at a position of a predetermined number of turns, and the remaining amount may be displayed stepwise when this specific identifier is detected. By adjusting the pressing force of the brake plate 8 in this manner, the looseness or tension of the packaging paper 10 can be prevented, and the tension of the packaging paper 10 is kept substantially constant. Accordingly, the possibility that the tension of the packaging paper 10 wound around the paper tube drum 7 becomes unstable and the defect such as the displacement of the welding position, which has conventionally occurred due to the unstable tension, is low, and the packaging accuracy is improved. be able to.

Next, if the reading speed at which the image sensor 4 reads the symbol 11 is within a predetermined speed range, the medicine is supplied from the hopper 1 to the packaging paper, and the packaging paper 10 is conveyed to the heater 2 side.

The temperature of the heater 2 is set by a microcomputer 12 based on a symbol 11 read by the image sensor 4 and is controlled to a temperature suitable for the material of the packaging paper 10.
The packaging paper 10 is conveyed to the heater 2 whose temperature is controlled in this way, and the medicine is sealed in the packaging paper 10. As described above, since the heater is controlled by the microcomputer 12 at a temperature corresponding to the material and thickness of the packaging paper, welding can be performed correctly without insufficient welding or the like. Note that the microcomputer 12 also serves as a temperature control means for setting and controlling the temperature of the heater 2 as described above.

In this manner, the medicine is packaged by the medicine packaging apparatus.

In the present embodiment, the materials and the like of a plurality of wrappers are stored in the microcomputer 12 as predetermined wrapper information in advance. May be determined in advance.In this case, an identifier indicating the determined material is stored in the microcomputer 12, and an identifier different from the stored identifier is read by the image sensor. Can be displayed as an error. At this time, the operation of the medicine packaging device may be stopped. As described above, by controlling the operation of the medicine packaging apparatus according to the material or the like of the packaging paper, the medicine can be surely packaged in the correct packaging paper according to the type of the medicine.

Further, the medicine packaging device is provided with a printing device for printing the dosage time and the like on the packaging paper, and the microcomputer 12 stores in advance the printing settings such as the printing position for each symbol 11 so that the The microcomputer 12 can automatically set the print setting corresponding to the type of wrapping paper. That is, it is also possible for the microcomputer 12 to have a role as print control means.

In the medicine packaging apparatus, the microcomputer 12 sets the heater temperature, adjusts the amount of the discharged paper, sets the printing position, and the like by reading the identifier of the packaging paper. All of these settings do not necessarily have to be performed, and the microcomputer 12 may be set so that at least one of the above settings is performed.

Also, in FIG. 1, the image sensor 4 is installed on the near side of FIG. 1 and the black light 5 is installed on the back side. However, even if the positional relationship between the image sensor and the black light is opposite to that of FIG. And may be arranged one above the other.

In the medicine packaging apparatus, the reading means is formed by an image sensor.
For example, a light receiving element such as a photodiode can be appropriately changed. When using a photodiode like this,
For example, if two photodiodes are used and the identifier is indicated by a combination of a line segment and a space like a bar code, the interval between the presence and absence of the line segment is detected by the two photodiodes. In addition, the reading unit can be configured at a lower cost than when the reading unit is configured by the image sensor. Further, the number of photodiodes is not limited to the above two, and can be changed as appropriate.
It can be changed as appropriate.

In the above embodiment, a black light for irradiating ultraviolet rays is provided in the medicine packaging apparatus, and an identifier emitted by irradiation of the black light on the packaging paper is read by an image sensor as reading means. However, the reading means is not limited to this. The reading means can be changed according to the form of the identifier. For example, if the identifier is formed by a barcode, the reading means can be a barcode reading device, and it is not necessary to provide a black light.

Further, as a reading means, for example, an image processing device can be applied as a device for taking in an identifier, comparing the identifier with a previously stored identifier, and detecting the meaning of the symbol when they match.

Further, even if the identifier is not provided on the packaging paper by printing, for example, when a synthetic resin for heat welding is applied to glassine paper or the like to form the packaging paper,
The fluorescent paint may be selectively provided on the edge of the packaging paper or the like, or the fluorescent paint may be formed in the shape of an identifier and attached to the edge of the packaging paper main body 10a. Further, the identifier is not limited to the combination of alphabets as shown in FIG. 2, and for example, as shown in FIG.
a, or as shown in FIG.
11b, or as shown in FIG. 5, a logo 11c such as a company name, etc., which can be appropriately changed. In short, any material can be used as long as it can indicate the type of packaging paper. Note that the same symbol array such as the logo 11c shown in FIG. 5 can be used as an identifier in common for all different types of packaging paper. In this case, the material, thickness, etc. of the packaging paper 10 can be used. The character spacing and size of an array of symbols, such as logos, can be made different for each type, and the type can be determined by the reading means, thereby serving as an identifier.

The ink for printing the identifier is as follows:
It is not limited to fluorescent materials such as fluorescent paints, and ordinary black ink,
Magnetic ink or the like may be used.

However, if the identifier is formed of a fluorescent material such as the above-described fluorescent paint, even when printing is performed on the packaging paper,
There is an advantage that the packaging paper can be formed with good appearance without affecting the printing such as the identifier blocking the printing.

The packaging paper information indicated by the identifier is not limited to the above-mentioned material, thickness, welding temperature and the like, but can be added or changed as appropriate as long as the information is related to the packaging paper such as the width of the packaging paper. Further, the packaging paper information is not limited to all of the above information, but may be information including at least one of the material, thickness, width, and the like of the packaging paper.

In the above-described embodiment, the identifier is printed on the side surface of the wrapping paper wound in a substantially cylindrical shape. However, the printing position of the identifier is not limited to the side surface. For example, as shown in FIG. It may be a side edge 10b on one surface of the wrapping paper. However, at this time, the interval between the identifiers is as shown in FIG.
Similar to the case shown in FIGS. 4 and 5, when the wrapping paper is wound around the paper tube drum, the inner peripheral side becomes dense ((b) in FIG. 6),
On the outer peripheral side, the printed matter is wrapped so as to be sparse ((a) in FIG. 6), and the space between the characters or the barcodes is increased toward the outer peripheral side of the packaging paper 10. The printing position of the identifier may be on both sides, the center of the front surface, or the like, and may be printed on both surfaces as well as on one surface.

In the case of printing as described above, the installation position of the identifier reading means may be changed according to the position where the identifier is printed.

Further, as a mode for providing an identifier, as shown in FIG. 7B, a permanent magnet 21 is provided on the end face of the paper tube 9 and a magnetic detecting means 22 such as a hole sensor as a reading means. May be arranged so as to face the paper tube 9 so that the magnetic field generated by the permanent magnet 21 can be detected, so that the present medicine packaging apparatus can be configured. In this case, the combination of the number and polarity of the permanent magnets 21, the magnitude of the magnetic force, the interval, and the like for each type of the packaging paper 10 is determined by the barcode (where `` magnitude of the magnetic force '' corresponds to the thickness of the line, Is set to correspond to the blank part), and each set corresponds to each identifier one-to-one,
By arranging the permanent magnet 21 on the side surface or the end surface (one end portion of the circumferential curved surface) of the paper tube 9 according to the setting, the Hall sensor can digitally read the magnetic field and detect it as a read pattern. The type of the packaging paper can be identified by the pattern. Such a permanent magnet
In order to provide 21 in the paper tube 9, it is possible to embed it in the paper tube 9 or to use a so-called sheet magnet. For example, as shown in FIG. 7B, a plurality of permanent magnets 21 are provided on both end surfaces of the paper tube 9, and the number, the magnitude of the magnetic force, and the number of magnets are increased at one end 21a and the other end 21b. The mounting angle ψ can be set to be different. That is, the amount of information of the read pattern is increased by changing the mounting angle に such as 0 ° and 60 ° on the one end 21a, and 0 ° and 90 ° on the other end 21b, for example, to increase the amount of packaging. Since the amount of information sufficient to represent the paper information can be set in the paper core drum 7, the packaging paper information can be set while minimizing the increase in the component cost. As described above, when both end surfaces are used, the amount of information that can be set by arranging identifiers increases, and it is possible to cope with various types of packing paper. And the paper tube 9 is replaced with the paper tube drum 7
When attached to a medicine packaging device, there is an advantage that a paper tube suitable for the present medicine packaging device can be identified, a proper packaging paper can be identified, and a proper attachment state can be confirmed. Further, with respect to such a permanent magnet 21, the magnetic detecting means 2 as the reading means 4
2 is provided close to the paper tube 9 in the same manner as in the case of the image sensor for reading the magnetic information, and further, as shown in FIG. A permanent magnet 23 for focusing the magnetic field on the permanent magnet 21 can be provided. Here, the vicinity may be, for example, behind the magnetic detection unit 22 as viewed from the permanent magnet 21, and the distance from the permanent magnet 21 according to the magnetic strength of the permanent magnet 21 may affect the magnetic field generated by the permanent magnet 21. It means that it should just be set to. When the permanent magnet 23 for magnetic field focusing on the permanent magnet 21 is provided in this manner, the amount of information sufficient to represent the packaging paper information can be set by the permanent magnet 21, and the permanent magnet 23 for magnetic field focusing is Magnetic field
There is an advantage that the magnetic detection means 22 can surely detect the magnetic information represented by the permanent magnet 21 by exhibiting the action of attracting and converging (lines of magnetic force).

The permanent magnet 21 can be used for detecting the paper feed speed. In this case, the reading pattern is repeatedly detected. However, if the period of the repetition is detected, there is an advantage that the paper feeding speed can be easily detected. As another form of the identifier, a metal piece (not shown) may be used instead of the permanent magnet 21, and a metal detecting means may be provided instead of the magnetic detecting means.

As described above, the configuration in which the identifier is provided at a predetermined position of the packaging paper main body for packaging the medicine allows the packaging paper to be specified in units including the packaging paper main body. Easy to implement. When the identifier is provided on the end face of the paper core, the packaging paper can be specified in units including the paper core 9. Therefore, it is also convenient for production management and the like in which the paper tube 9 is recycled. Incidentally, the heat welding means is not limited to the above-mentioned heater, and may be appropriately changed, for example, a thermocompression device generally used conventionally, such as a pressure seal device.

Further, when an error has occurred, it is displayed on the display device in the above embodiment, but the alarm means can be changed as appropriate such as a buzzer.

If the packaging paper provided with the identifier is manufactured and sold at a specific place such as a factory, the identifier can be used for manufacturing management like the manufacturing lot number, and the sales route can be grasped. Hygiene management and inventory management become easy.
