Description

  The present invention relates to a label continuous sheet printing apparatus that prints a barcode image on a label that is detachably attached to a strip-shaped release paper.

  Labels are attached to drug containers such as ampoules and vials in order to identify the contents. As such a label, an adhesive layer is applied on the back surface of a label base material made of paper, synthetic resin, or the like, and information such as a drug name or content is printed on the surface in advance. And after a pharmaceutical is manufactured, the label is stuck to the chemical | medical agent container by the label sticking apparatus in the packaging process in the manufacturer of a pharmaceutical.

  Information printed on the label includes invariant information such as a drug name, content, and manufacturing company name, and variable information such as a manufacturing date, an expiration date, a serial number, and a manufacturing lot number. Among these, if variable information is printed on the label in advance, the printed label is wasted when the product cannot be manufactured as scheduled. For this reason, it is better to print the variable information immediately before attaching the label on which the invariant information is printed in advance to the medicine container. As this printing means, it is conceivable to use a general laser printing device or thermal printing device and print numbers or alphabetic character data on the label when the label is applied.

  In hospitals, medical facilities, nursing care facilities, etc., doctors examine patients, determine prescriptions, issue medical records, and nurses perform medical practices on patients according to the medical records. At this time, the nurse visually confirms the prescription contents of the medical chart issued by the doctor, and visually confirms the drug name printed on the label affixed to the drug container, the character string indicating the expiration date, etc. We carry out medical practice after confirming.

  However, due to the carelessness of nurses, patients with different disease names are mistakenly administered, drugs are administered in the wrong way, drugs with expired expiration dates are administered, and confirmation work is performed, but overlooked. There are many accidents.

  For this reason, the manufacturer of the drug to be attached with a label prints variable information such as the date of manufacture, expiry date, serial number, and production lot number printed as a character string immediately before application as a barcode. Thus, when a medicine is used in a hospital or the like, the medicine information displayed by the barcode can be optically read and managed by a computer.

  However, pharmaceutical manufacturers print on the surface of the label just before applying the label to the drug container on the line where the label is applied to the drug container by the label applying device. In order to print barcodes with a general laser printer or thermal printer, the label cannot be printed unless the speed of the label application line is reduced. There is.

  Therefore, according to the inkjet recording method, there is an advantage that a high-resolution image can be obtained at high speed. There is also a problem that clogging occurs and ink cannot be ejected during printing, leading to deterioration in printing quality.

  The problem of the present invention is that the label can be printed without slowing down the labeling line, and the medicine information is displayed on the label attached to the medicine container in order to prevent carelessness due to carelessness. An object of the present invention is to provide a label continuous sheet printing apparatus capable of printing a barcode image.

Means for solving problems and effects of device

In order to solve the above problem, the label continuous sheet printing device of the present invention is:
A label that has an adhesive layer on the back side and a printable area on the front side and a printed part of predetermined data including the drug name and content of the medicine is affixed to the strip-shaped release paper so that it can be peeled at predetermined intervals. To form a continuous label sheet,
A transport device that transports the continuous label sheet in the longitudinal direction at a predetermined speed, a label stripping device that strips the label of the continuous label sheet transported by the transport device from the release paper to stick the label to a sticking object, and a label strip A printing device for printing on the printable area of the label by an inkjet method located upstream of the continuous sheet conveying direction of the device,
The printing apparatus has a print head having a plurality of nozzles capable of printing a barcode,
By discharging ink from the print head, variable information including the date of manufacture and expiration date of the pharmaceutical is printed as a barcode image in a printable area of the label.

  According to such a printing apparatus, the variable information including the date of manufacture and the expiration date of the medicine is printed as a barcode image, so that the variable information can be read from the barcode image. Therefore, when using a medicine with a label printed by this printing device, it is possible to easily confirm the date of manufacture and expiration date of the medicine by reading the variable information of the medicine from the barcode image. Medical errors such as oversight by visual confirmation of character strings can be prevented.

  In addition, since the barcode image created as image data in advance is printed by the inkjet method, printing can be performed at high speed, and further, the conveyance stop time of the label continuous sheet for printing can be shortened, Barcode images can be printed without slowing down the labeling line.

The printing apparatus includes an ultraviolet irradiation device that irradiates ultraviolet rays onto a label printed by the printing device adjacent to the printing device,
Printing is performed using ultraviolet curable ink having ultraviolet curable and chemical resistance as ink ejected from the print head.

  As described above, by using the ultraviolet curable ink, it is possible to prevent clogging of the nozzle due to the ink solvent evaporating from the nozzle of the print head and the ink in the nozzle solidifying like the conventional solvent ink. . Furthermore, since the display with ultraviolet curable ink is excellent in chemical resistance and alcohol resistance, the display after printing can be a display that does not blur due to the chemical or alcohol.

  Moreover, the label continuous sheet printing apparatus of the present invention can simultaneously print the invariant information including the drug name and content of the drug as a barcode image. Not only variable information including the date of manufacture and expiration date of pharmaceutical products, but also invariant information such as drug names of pharmaceutical products are printed as barcode images. A lot of information can be read from the barcode image.

  Further, the continuous label sheet is conveyed intermittently or continuously at a speed of 200 mm / s to 500 mm / s by the conveying device, and the print head is operated while feeding in the conveying direction to discharge the ink and label. Can be printed. In this way, the time required for printing can be shortened by ejecting ink from the print head while feeding in the conveying direction of the continuous label sheet and printing on the label. Therefore, the continuous label sheet can be conveyed at high speed, and a plurality of labels on the continuous label sheet can be printed at high speed.

In addition, the printing apparatus includes a storage cap unit for the print head to stand by the side of the conveyed continuous label sheet, and a linear rail that moves the print head waiting by the storage cap unit to the printing position of the continuous label sheet. With
The print head printed on the label is moved to the storage cap portion by the linear rail, and the nozzle surface of the print head is hermetically covered in the storage cap portion.

  According to this configuration, when printing on the label on the continuous label sheet by the linear rail, the print head can be moved to the printing position on the conveyance path of the continuous label sheet, and when printing is paused. Can be moved to the storage cap portion which is the standby position of the print head.

  At this time, if ultraviolet rays are irradiated to the ink in the nozzles during which ink discharge is suspended, the ink hardens and the nozzles become clogged, and ink discharge cannot be resumed. By covering the surface, nozzle clogging due to the curing of the ink by irradiation of ultraviolet rays is prevented, and dust, dust, and dust are prevented from entering.

In addition, the storage cap portion includes a drive mechanism for moving up and down,
The drive mechanism can be configured to raise the storage cap portion toward the print head moved to the storage cap portion by the linear rail so as to cover the space between the print head and the print head. According to this, the storage cap portion can be moved up and down, so that when the print head moves, a gap is formed between the nozzle surface of the print head and the storage cap portion, and the structure is easy to move. Become. Furthermore, since the storage cap portion is raised after the print head is stopped, airtightness is reliably maintained.

In addition, the storage cap portion includes a contact portion that is pressed when the print head moves to a standby position, and is movable with the print head.
A cam with an inclined slide surface is arranged in the storage cap part, and the storage cap part that moves together with the print head moves toward the print head by the interposed inclined cam so that the space between the print head and the print head is airtight. It is possible to configure so as to cover. Thus, even if the storage cap portion is not provided with a special drive mechanism, the operation for airtightness of the storage cap portion can be operated together by the movement operation of the print head on the linear rail.

In addition, a label suction unit that vacuum-sucks the continuous label sheet from the back side is provided at a position facing the print head during printing operation across the continuous label sheet.
The label suction unit is configured to perform printing while holding the label on the conveyed continuous label sheet in a stable and flat state. According to this configuration, the printing portion of the label on the label continuous sheet can be kept flat and stable at the time of printing, so that printing with good print quality can be stably performed.

  Moreover, the conveying apparatus is provided with the label supply mechanism which supplies a label continuous sheet from the state wound by roll shape. With this configuration, it is possible to appropriately supply a continuous label sheet in a roll shape to the printing apparatus.

Further, in place of the label peeling device according to claim 1, a label winding mechanism for winding the continuous label sheet after printing in a roll shape,
The roll-shaped continuous label sheet wound up by the label winding mechanism is characterized in that it is peeled off from the release paper in order to stick the label to the sticking object by a label peeling device arranged separately.

  According to this structure, the label continuous sheet after printing can be packed and stocked compactly. And the label continuous sheet after printing wound up in the roll shape can be set and used for the label peeling apparatus separately arrange | positioned.

The image A (FIG. 2) formed by ejecting ink from the print head 41 on the label 102 is irradiated with ultraviolet rays from the ultraviolet irradiation lamp 8a, whereby the ink forming the image A is cured and labeled. It adheres to 102. The blower 83 is used to cool the ultraviolet irradiation lamp 8a, which generates heat at the time of ultraviolet irradiation and is at a high temperature, and sucks and discharges air.

  As shown in FIGS. 3b and 4a, the storage cap portion 43 includes a cap surface 43a, a cap frame 43b, and a cam 60, and the cap surface 43a and the cap frame 43b are integrated to form an abutment portion. 43c. The storage cap portion 43 is disposed so as to be located on the side of the conveyance path of the label continuous sheet 100. The cap surface 43a airtightly covers the nozzle surface 41a (FIG. 5) of the print head 41 in the print pause state, prevents dust and dust from entering the nozzle surface, and further, the ink in the nozzle is absorbed by light. It protects against hardening.

  The cap surface 43 a is configured to be movable up and down by a cam 60. That is, as shown in FIG. 4a, the cam 60 has an inclined slide surface 60x. A slide bar 43d is connected to the cap frame 43b of the storage cap portion 43, and the slide bar 43d slides on the slide surface 60x. When the head unit 42 including the print head 41 is moved to the standby position by the linear rail 44, the contact portion 43c of the storage cap portion 43 is pressed by the head unit 42 and moved together. At this time, the slide bar 43d slides on the slide surface 60x to push up the storage cap portion 43 along the inclination of the slide surface 60x.

  As another embodiment, as shown in FIG. 4b, for example, the cap surface 43a can be moved up and down by a drive mechanism 43X. That is, the drive mechanism 43X is provided with a cam 43e, and the cap surface 43a is pushed up through the support portion by driving the cam 43e. Furthermore, the cap surface drive mechanism may be configured to move up and down as an air cylinder.

  Since the cap surface 43a can be moved up and down in this way, when the head unit 42 moves, a gap is formed between the nozzle surface 41a of the print head 41 and the cap surface 43a, so that the cap unit 43 can move easily. After the movement, the cap surface 43a is pushed up and pressed against the nozzle surface 41a of the print head 41.

  Returning to FIG. 3 a, the linear rail 44 is installed in the main body of the printing apparatus 4 in parallel to the width direction with respect to the conveyance direction of the label continuous sheet 100. A head unit 42 is attached to the linear rail 44 via a slide portion 49 and moves linearly in the width direction of the label continuous sheet 100. The slide part 49 and the linear rail 44 are mechanisms for adjusting the position of the head unit 42. As this moving mechanism, for example, a ball screw that reciprocates the head unit 42 in the width direction and a motor are formed. A screw is attached to the head unit 42, and this screw is screwed into the ball screw. The head unit 42 can be moved by rotating the screw forward and backward.

  The label suction unit 45 is formed long in the conveyance direction of the label continuous sheet 100, and includes a housing 45a fixed on the machine base 50, a suction plate 45b attached to the upper surface of the housing 45a, and a suction plate. The suction fan 45c (FIG. 1) attached to the lower side is provided, and a negative pressure suction wind is generated by driving the suction fan 45c. In this way, the continuous label sheet 100 adsorbed on the adsorption plate 45b of the label adsorption unit 45 by the negative pressure suction wind has a predetermined space for ejecting ink from the print head 41, and the print head It faces 41 in parallel.

  The label printing process by the printing apparatus 1 for the label continuous sheet 100 will be described. First, the label winding mechanism 7 is rotationally driven, and the label continuous sheet 100 is conveyed onto the label suction unit 45. In this state, the suction fan 45c of the label suction unit 45 is driven, and the label continuous sheet 100 is conveyed while being sucked by the label suction unit 45. The head unit 42 including the print head 41 stands by in a state where the nozzle surface 41a of the print head 41 is airtightly covered in the storage cap portion 43 so that the ink in the nozzle is not cured when the printing apparatus 4 is not in operation. However, at the time of operation, the linear rail 44 moves from the state shown in FIG. 3A to the state shown in FIG. 3B and is positioned at the printing position on the conveyed continuous label sheet 100.

  The front end position of the label 102 is detected by the sensor 5a, and the print position is indicated by sending a signal. The printing device 4 receives a print signal from a predetermined host device Y, and ejects ink from the print head 41 of the head unit 42. The discharged ink is irradiated with ultraviolet rays by the ultraviolet irradiation device 8, and the image A is printed on the label 102.

  The printed label 102 is conveyed to a label peeling device 3 provided downstream from the printing device 4. When the sensor 5b detects that the label 102 has been fed to a predetermined position, the conveyance of the label 102 is stopped. In the label peeling apparatus 3, the release paper 101 is folded back in the direction away from the label 102 by the folding plate 31, whereby the label 102 is sequentially peeled from the front side in the transport direction, and the transport of the release paper 101 is stopped at that time. Thus, the label 102 is supplied in a state of protruding from the release paper 101. The label 102 thus peeled off is attached to a drug container such as an ampoule that is an attachment object in the attachment object placement device.

  Thus, the continuous label sheet 100 is conveyed intermittently by repeatedly moving and stopping by detection by the sensors 5a and 5b. Using the paper feed in which the continuous label sheet 100 is intermittently conveyed, ink is ejected from the print head 41 of the printing apparatus 4 while feeding in the conveyance direction of the continuous label sheet 100, and printing is performed on the label 102. It has been broken. For this reason, the time required for printing can be shortened. In this way, paper feeding and printing are repeated to print on the plurality of labels 102 on the long continuous label sheet 100, and the image A can be printed on the plurality of labels 102 at high speed.

Next, another embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member similar to the said embodiment, and description is abbreviate | omitted.
In FIG. 6, instead of the label peeling device 3 in the printing device 1 for the label continuous sheet 100 described above, the label continuous sheet 100 is used as the label winding mechanism 7 that winds the printed label continuous sheet 100 into a roll. The printing apparatus 10 is configured.

  In this configuration, the label peeling device 3 (FIG. 1) of the first embodiment is not continuously arranged, and the label continuous sheet 100 after printing is kept in a state where the label 102 is stuck on the release paper 101. It is wound up in a roll shape. According to this, the label continuous sheet 100 after printing can be packed and stocked in a compact manner. For this reason, the label continuous sheet 100 is printed before the label 102 is affixed to an object to be applied (a drug container such as an ampoule), and the label continuous sheet 100 in a roll shape is separately separated. By loading the apparatus, the label 102 can be attached to an object to be attached (a drug container such as an ampoule). Also, by printing a plurality of label continuous sheets 100, the plurality of roll-formed label continuous sheets 100 can be loaded into a plurality of label peeling devices separately arranged, and a plurality of lines can be formed. It is possible to operate at the same time and attach the label 102 to an object to be attached (a drug container such as an ampoule).

  Further, when the printing apparatus 10 for the continuous label sheet 100 is provided with the discharge port 11 and the printed continuous label sheet 100 is sent out from the discharge port 11, a label in which the continuous label sheet 100 sent out from the discharge port 11 is separately arranged. By guiding to the peeling device, the label 102 can be attached to an object to be attached (a drug container such as an ampoule). For this reason, it is possible to print a barcode image by incorporating the printing device 10 for the continuous label sheet 100 into an existing label peeling device.

  By attaching the caster 12 to the printing device 10 of the continuous label sheet 100, the printing device 10 of the continuous label sheet 100 can be moved to a necessary line, and by connecting to the label peeling device of the destination line, It is possible to print a barcode image on the label 102 in the line and attach the label 102 to an object to be attached (a drug container such as an ampoule).

Next, a management system using a label printed by the label continuous sheet printing apparatus of the present invention will be described with reference to FIG.
That is, in order to prevent medical errors due to carelessness of doctors and nurses, patient data such as name, date of birth, sex, blood type, etc., as well as patient-related information after a doctor's examination are stored in the host computer 200. The wristband 201 is stored together with the patient ID, and the wristband 201 with the barcode B having such information is issued to the patient. The drug container 105 has a barcode image A indicating variable information such as the date of manufacture, expiration date, serial number, and production lot number of the pharmaceutical, and invariant information such as the drug name, content, quantity, and manufacturing company name. A printed label 102 is affixed. Then, when a medical action is performed on the patient, the barcode B of the patient wristband 201 and the barcode image A printed on the label 102 affixed to the drug container 105 are read and collated by the reader 202, If the verification result is OK, the drug is administered to the patient. Furthermore, medical errors can be prevented by a method of storing the history of medicines administered to a patient in the host computer 200 as patient related information. At this time, by displaying variable information on the barcode image A printed on the label 102 affixed to the medicine container 105, it can be confirmed that the medicine is not expired, and invariant information is included. Thus, the name of the medicine administered to the patient can be stored in the host computer 200.

  When using a medicine by a doctor, nurse, or the like at a medical site, it is conceivable that the label 102 is touched with a hand that has been sterilized with alcohol or other chemicals are attached to the label 102. When the label 102 is printed with a solvent ink such as a conventional dye-based ink or pigment-based ink, the display of the label 102 may be blurred by alcohol or chemicals. However, by using an ultraviolet curable ink, chemical resistance is improved. Therefore, there is an effect of preventing bleeding of the label 102 display.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these forms, In the range of the sameness as the invention embodied in these, it can change suitably and can implement.
