That is, the inkjet head 51 of the printing part 50 is controlled by the control part 103 so that a specific printing pattern may be printed on the printable tablet T on the conveyance belt 21. Specifically, the printable tablet T passing on the conveyor belt 21 below the first imaging unit 40 reaches the printing start timing of the printing position directly under the inkjet head 51. Based on the above printing conditions, the inkjet head 51 printed. In the inkjet head 51, ink is appropriately ejected from each nozzle 51a, and a printing pattern (for example, serial number, alphabet, katakana, symbol, figure) is printed on the upper surface of the tablet T, that is, the surface to be printed. The ink coated on the tablet T is dried during conveyance. In addition, a drying unit (not shown) for drying with gas or heat may be provided, and the ink may be dried by this drying unit.
其後,藉由第2攝像部60拍攝搬送帶21上之已印刷之錠劑T。詳細而言,搬送帶21上之已印刷之錠劑T以到達第2攝像部60正下之攝像位置之第2攝像時序,藉由第2攝像部60拍攝,且將藉由該第2攝像部60之拍攝獲得之第2圖像發送至控制裝置100。Thereafter, the printed tablet T on the conveyor belt 21 is photographed by the second imaging unit 60 . Specifically, the printed tablet T on the conveyer belt 21 is photographed by the second imaging unit 60 at the second imaging timing when it reaches the imaging position directly below the second imaging unit 60, and will be captured by the second imaging unit 60. The second image captured by the part 60 is sent to the control device 100 .
藉由控制裝置100之圖像處理部101解析該第2圖像。詳細而言,藉由圖像處理部101取得印刷於錠劑T之已印刷之印刷圖案相關之資訊,即已印刷之印刷圖案之印刷位置或形狀、尺寸。藉由圖像處理部101解析自第2攝像部60發送之第2圖像,產生顯示錠劑T中已印刷之印刷圖案之印刷位置或形狀、尺寸之檢查資訊,且保存於記憶部102。The second image is analyzed by the image processing unit 101 of the control device 100 . Specifically, the image processing unit 101 acquires information related to the printed pattern printed on the tablet T, that is, the printed position, shape, and size of the printed pattern. The second image sent from the second imaging unit 60 is analyzed by the image processing unit 101 to generate inspection information showing the printing position, shape, and size of the printed pattern printed on the tablet T, and store it in the memory unit 102 .
基於該檢查資訊,藉由控制部103執行印刷狀態檢查。詳細而言,基於保存於記憶部102之上述之印刷位置或形狀、尺寸相關之檢查資訊,藉由控制部103判斷印刷圖案是否正常印刷於錠劑T上,產生顯示錠劑T之印刷好壞之印刷好壞資訊,且保存於記憶部102。例如,印刷狀態檢查中,將使用於印刷之印刷圖案作為檢查用之印刷圖案,保存於記憶部102,將檢查用之印刷圖案之特定之印刷位置或形狀、尺寸相關之良品資訊、及保存於記憶部102之實際的已印刷之印刷圖案之印刷位置或形狀、尺寸相關之檢查資訊進行比較,判斷是否將印刷圖案正常印刷於錠劑T上(合格或不合格)。Based on the inspection information, the printing state inspection is executed by the control unit 103 . In detail, based on the above-mentioned inspection information related to the printing position, shape, and size stored in the memory unit 102, the control unit 103 judges whether the printing pattern is normally printed on the tablet T, and generates information indicating whether the printing of the tablet T is good or bad. Print good or bad information, and save in the memory unit 102. For example, in the printing status inspection, the printed pattern used for printing is stored in the memory unit 102 as the printed pattern for inspection, and the specific printing position, shape, and size-related good product information of the printed pattern for inspection are stored in the The memory unit 102 compares the inspection information related to the printing position, shape, and size of the actual printed printing pattern to determine whether the printing pattern is normally printed on the tablet T (pass or fail).
最後,藉由回收部90回收搬送帶21上之錠劑T。詳細而言,當檢查後之錠劑T隨著搬送帶21之移動而位於搬送帶21之下游側之端部時,自保持於搬送帶21之狀態解除,自搬送帶21落下,藉由回收部90回收。此時,合格錠劑之錠劑T直接落下,藉由回收部90作為良品回收,但不合格錠劑或非印刷錠之錠劑T於自搬送帶21落下之中途藉由空氣之吹附而與良品分開,藉由回收部90作為不良品回收。Finally, the tablet T on the conveyor belt 21 is recovered by the recovery unit 90 . Specifically, when the inspected tablet T is located at the end of the downstream side of the conveyor belt 21 as the conveyor belt 21 moves, it is released from the state held by the conveyor belt 21, falls from the conveyor belt 21, and is recovered by Section 90 Recycling. At this time, the tablets T of qualified tablets fall directly, and are recovered as good products by the recovery part 90, but the tablets T of unqualified tablets or non-printed tablets are blown by air during the fall from the conveyor belt 21. It is separated from good products and recovered as defective products by the recovery unit 90 .
此種印刷步驟中,自所有吹氣部81分別始終吹出氣體。自該所有吹氣部81分別吹出之氣體吹附至蓋70之下表面,即與蓋部70內之感測器30、第1攝像部40及第2攝像部60對向之各透光構件71、72之下表面。藉此,由於將附著於各透光構件71、72之下表面,詳細而言,自圖3所示之各貫通孔70a、70b、70d露出之各透光構件71、72之下表面之異物(例如粉末或廢料)去除,故可抑制感測器30檢測附著於透光構件71之下表面之異物而誤檢測錠劑T,又,抑制第1攝像部40或第2攝像部60等攝像部拍攝附著於各透光構件71、72之下表面之異物而誤檢測錠劑T。又,由於自所有吹氣部81分別始終吹出氣體,故亦可抑制異物附著於自各貫通孔70a、70b、70d露出之各透光構件71、72之下表面。如此,可抑制因異物附著所致之誤檢測,故可效率良好地對錠劑T進行印刷。In such a printing step, gas is always blown from all the blowing units 81 . The gas blown out from all the blowing parts 81 is blown onto the lower surface of the cover 70, that is, the light-transmitting members facing the sensor 30, the first imaging part 40 and the second imaging part 60 in the cover part 70 71, 72 below the surface. Thereby, since the foreign matter attached to the lower surface of each light-transmitting member 71, 72, specifically, the lower surface of each light-transmitting member 71, 72 exposed from each through-hole 70a, 70b, 70d shown in FIG. (such as powder or waste) is removed, so it can prevent the sensor 30 from detecting foreign matter attached to the lower surface of the light-transmitting member 71 and falsely detect the tablet T, and prevent the first imaging unit 40 or the second imaging unit 60 from imaging The foreign matter attached to the lower surface of each light-transmitting member 71, 72 is partially photographed, and the tablet T is falsely detected. Moreover, since the gas is always blown out from all the air blowing parts 81, it is also possible to suppress foreign matter from adhering to the lower surfaces of the light-transmitting members 71, 72 exposed from the through holes 70a, 70b, and 70d. In this way, false detection due to adhesion of foreign matter can be suppressed, so that the tablet T can be printed efficiently.
此處,例如當感測器30檢測出附著於透光構件71之下表面之異物時,產生錯判錠劑T來到感測器30之正下之時序而檢測之誤檢測。對該誤檢測之錠劑T不進行正確印刷,導致該錠劑T作為不合格錠劑(不良品)排出。又,當第1攝像部40或第2攝像部60等攝像部拍攝並檢測附著於透光構件71、72之下表面之異物時,產生異物附著於錠劑T之誤檢測。對該誤檢測之錠劑T不進行印刷,導致該錠劑T被作為非印刷錠劑(不良品)排出。如此,當異物附著於各透光構件71、72之下表面,即蓋部70之下表面時,無法效率良好地對錠劑T印刷,但藉由如上述般,利用各吹氣部81將異物自蓋部70之下表面去除,可抑制因異物附著所致之誤檢測,且效率良好地對錠劑T進行印刷。Here, for example, when the sensor 30 detects a foreign object adhering to the lower surface of the light-transmitting member 71 , an erroneous detection occurs by misjudging the timing at which the tablet T comes directly under the sensor 30 . The incorrectly detected tablet T is not printed correctly, and the tablet T is discharged as a defective tablet (defective product). In addition, when the imaging units such as the first imaging unit 40 or the second imaging unit 60 capture and detect foreign matter adhering to the lower surfaces of the light-transmitting members 71 and 72, false detection of foreign matter adhering to the tablet T occurs. The erroneously detected tablet T is not printed, and the tablet T is discharged as a non-printed tablet (defective product). In this way, when foreign matter adheres to the lower surface of each light-transmitting member 71, 72, that is, the lower surface of the lid portion 70, efficient printing on the tablet T cannot be performed. Foreign matter is removed from the lower surface of the cover portion 70, and false detection due to foreign matter adhesion can be suppressed, and printing on the tablet T can be performed efficiently.
又,吹氣部81之氣體之吹出方向為俯視時與搬送方向H1水平正交之方向。藉此,至少僅於通過吹氣部81之下方時,錠劑T暴露於氣流中,因而可抑制自吹氣部81吹出之氣體對錠劑T之姿勢造成影響。例如,認為於吹氣部81之氣體之吹出方向與搬送方向H1平行之情形時,會導致氣流長時間吹打排列於搬送方向之複數個錠劑T,致使複數個錠劑T之姿勢變更。當錠劑T之姿勢變更時,導致由感測器30檢測出之錠劑T之位置與由第1攝像部40拍攝之錠劑T之位置或姿勢變化。即,無法順利進行之後的拍攝或印刷,且難以效率良好地對錠劑T進行印刷。又,可抑制自吹氣部81吹出之氣體對噴墨頭51之印刷造成影響。例如,當自噴墨頭51噴出之墨水之前進方向因氣流而彎曲時,產生印刷不良,難以效率良好地對錠劑T進行印刷。因此,氣體之吹出方向期望為俯視時與搬送方向H1水平交叉之方向中,即避開噴墨頭51之正下之方向(例如非朝向搬送方向H1之下游側之方向的方向),最期望為與搬送方向H1正交之方向。Moreover, the blowing direction of the gas of the blowing part 81 is the direction horizontally perpendicular to the conveyance direction H1 in planar view. Thereby, since the tablet T is exposed to the airflow at least only when it passes below the blowing part 81, it can suppress that the posture of the tablet T is affected by the gas blown from the blowing part 81. For example, it is considered that when the blowing direction of the gas from the blowing unit 81 is parallel to the conveying direction H1, the airflow will blow the plurality of tablets T arranged in the conveying direction for a long time, resulting in a change in the posture of the plurality of tablets T. When the posture of the tablet T changes, the position of the tablet T detected by the sensor 30 and the position or posture of the tablet T captured by the first imaging unit 40 change. That is, subsequent imaging and printing cannot be performed smoothly, and it is difficult to print on the tablet T efficiently. In addition, it is possible to suppress the influence of the gas blown from the gas blowing unit 81 on printing by the inkjet head 51 . For example, when the forward direction of the ink ejected from the inkjet head 51 is bent by the air flow, printing failure occurs, making it difficult to print efficiently on the tablet T. Therefore, the blowing direction of the gas is desirably in the direction horizontally intersecting with the conveyance direction H1 in a plan view, that is, avoiding the direction directly below the inkjet head 51 (for example, the direction not facing the downstream side of the conveyance direction H1), the most desirable It is a direction orthogonal to the conveyance direction H1.
另,印刷對象之錠劑T為如素錠或OD錠(口腔內崩解錠)般之凝固粉末而成形之錠劑之情形時,錠劑T之粉末積存於搬送帶21,或該粉末漂浮,故易於蓋部70之下表面附著粉末。因此,亦可根據錠劑T之種類,改變自各吹氣部81分別吹出之氣體之流動強度。例如,錠劑T之種類為素錠或OD錠之情形時,亦可增強氣體之流動,錠劑T之種類為不易出現異物(例如粉末)之錠劑之情形時,亦可減弱氣體之流動,又,可於增強氣體之流動後回復至原來的強度。In addition, when the tablet T to be printed is a tablet made of solidified powder such as a plain tablet or an OD tablet (orally disintegrating tablet), the powder of the tablet T is accumulated on the conveyor belt 21, or the powder floats , so it is easy to attach powder to the lower surface of the cover portion 70 . Therefore, the flow intensity of the gas blown from each blowing part 81 can also be changed according to the kind of tablet T. For example, when the type of tablet T is a plain tablet or an OD tablet, the flow of gas can also be enhanced, and when the type of tablet T is a tablet that is less prone to foreign matter (such as powder), the flow of gas can also be weakened , Also, it can return to the original strength after enhancing the flow of gas.
(氣體之吹出強度調整之處理例) 接著,對自氣體吹出強度調整之處理例1至處理例6,參照圖6至圖11進行說明。該等處理例1至處理例6之各處理可單獨使用,又,可並列或串列地適當組合使用。 (Processing example of adjusting the blowing intensity of gas) Next, processing example 1 to processing example 6 of self-gas blowing intensity adjustment will be described with reference to FIGS. 6 to 11 . Each of these treatment examples 1 to 6 may be used alone, or may be used in combination appropriately in parallel or in series.
(處理例1) 如圖6所示,於處理例1中,於步驟S1中,控制部103以將自各吹氣部81分別吹出之氣體之流動設為第1強度之方式,控制各吹氣部81。其後,於步驟S2中,控制部103判斷感測器30檢測錠劑T之狀態是否維持了特定時間以上。 (processing example 1) As shown in FIG. 6 , in processing example 1, in step S1 , the control unit 103 controls each blowing unit 81 so that the flow of the gas blown out from each blowing unit 81 is at the first intensity. Thereafter, in step S2, the control unit 103 determines whether the state in which the sensor 30 detects the tablet T has been maintained for a predetermined time or longer.
步驟S2中,當控制部103判斷感測器30檢測錠劑T之狀態維持了特定時間以上時(步驟S2之是(Yes)),步驟S3中,以將自各吹氣部81中對應於感測器30之吹氣部81吹出之氣體之流動設為第1強度至第2強度之方式,控制對應於感測器30之吹氣部81。其後,處理返回至步驟S2。另,第2強度強於第1強度(第2強度>第1強度)。In step S2, when the control unit 103 judges that the sensor 30 detects that the state of the tablet T has been maintained for more than a specific time (step S2 (Yes)), in step S3, the corresponding sensor in each blowing unit 81 is selected. The flow of the gas blown by the blowing part 81 of the detector 30 is set from the first intensity to the second intensity, and the blowing part 81 corresponding to the sensor 30 is controlled. Thereafter, the process returns to step S2. In addition, the second intensity is stronger than the first intensity (second intensity>first intensity).
另一方面,步驟S2中,當控制部103判斷感測器30檢測錠劑T之狀態未維持特定時間以上時(步驟S2之否(No)),步驟S4中,以將自各吹氣部81分別吹出之氣體之流動維持於第1強度之方式,或,以將自各吹出部81中對應於感測器30之吹氣部81吹出之氣體之流動自第2強度返回至第1強度之方式,控制對應於感測器30之吹氣部81。其後,處理返回至步驟S2。On the other hand, in step S2, when the control unit 103 judges that the sensor 30 detects that the state of the tablet T has not been maintained for more than a specific time (No (No) in step S2), in step S4, the air blowing unit 81 The flow of the respectively blown gas is maintained at the first intensity, or the flow of the gas blown from the blowing portion 81 corresponding to the sensor 30 in each blowing portion 81 is returned from the second intensity to the first intensity , to control the air blowing part 81 corresponding to the sensor 30 . Thereafter, the process returns to step S2.
此處,雷射位移計等感測器30檢測錠劑T之狀態意指感測器30之輸出值(檢測值)為ON(接通)之狀態,感測器30檢測錠劑T之狀態是否維持了特定時間以上,根據感測器30之輸出值是否持續特定時間以上為「ON」而判斷。感測器30未誤檢測之情形,重複:於每次將錠劑T搬送至感測器30之正下時成為「ON」,於錠劑T不存在於感測器30之下方時,成為「OFF(斷開)」。即,正常時,感測器30交替重複「ON」與「OFF」。異常時(誤檢測時),持續特定時間以上保持「ON」之狀態。該判斷處理例如於其他處理例中亦同樣。Here, the state of the tablet T detected by a sensor 30 such as a laser displacement meter means that the output value (detection value) of the sensor 30 is ON (connected), and the sensor 30 detects the state of the tablet T. Whether it has been maintained for a specific time or not is judged based on whether the output value of the sensor 30 is "ON" for a specific time or longer. The situation where the sensor 30 does not misdetect is repeated: every time the tablet T is transported directly under the sensor 30, it becomes "ON", and when the tablet T does not exist under the sensor 30, it becomes "ON". "OFF (disconnect)". That is, normally, the sensor 30 repeats "ON" and "OFF" alternately. In the event of an abnormality (during false detection), it remains "ON" for a certain period of time. This determination processing is also the same in other processing examples, for example.
又,第1強度或第2強度為特定值。氣體之流動強度意指變更氣體之流速或流量等而變化者。例如,藉由提高氣體之流速,或提高氣體之流量,而加強氣體之流動,相反,藉由降低氣體之流速,或降低氣體之流量,而減弱氣體之流動。上述之特定時間例如設定為較維持通常時(異常時以外之時)之感測器30檢測錠劑T之狀態之時間更長。第1強度或第2強度、特定時間等資訊係預先設定於記憶部102,亦可根據使用者對輸入裝置100a之輸入操作而變更。Also, the first intensity or the second intensity is a specific value. The flow intensity of gas refers to the one that changes by changing the flow velocity or flow rate of gas. For example, by increasing the flow rate of the gas, or increasing the flow rate of the gas, the flow of the gas is enhanced, and conversely, by decreasing the flow rate of the gas, or reducing the flow rate of the gas, the flow of the gas is weakened. The above-mentioned specific time is set to be longer than the time in which the sensor 30 detects the tablet T in the normal time (other than abnormal time), for example. Information such as the first intensity, the second intensity, and the specific time are preset in the memory unit 102, and can also be changed according to the user's input operation on the input device 100a.
另,控制部103於感測器30檢測錠劑T之狀態未維持特定時間以上之情形時,以將氣體之流動自第2強度返回至第1強度之方式,控制對應於感測器30之吹氣部81,但並非限定者,例如步驟S3中,亦可於增強氣體之流動後經過特定時間之情形,以將氣體之流動自第2強度返回至第1強度之方式,控制對應於感測器30之吹氣部81。該情形時,可無需步驟S4之處理。In addition, when the sensor 30 detects that the state of the tablet T has not been maintained for a specified time or longer, the control unit 103 controls the gas flow corresponding to the sensor 30 in such a manner that the flow of the gas returns from the second intensity to the first intensity. Blowing part 81, but not limited thereto, for example, in step S3, it is also possible to return the flow of gas from the second intensity to the first intensity after a specific time has elapsed after enhancing the flow of gas, and control the corresponding sensory intensity. The air blowing part 81 of the detector 30. In this case, the processing of step S4 may not be necessary.
又,亦可藉由例如顯示器或燈、儀表等輸出裝置100b,對使用者報知氣體流動之強度為第1強度或第2強度,又,增強或減弱。藉此,使用者可掌握氣體流動之強度為何種程度之強度。In addition, the output device 100b, such as a display, a lamp, or a meter, can also be used to inform the user that the intensity of the gas flow is the first intensity or the second intensity, and that it is increased or decreased. Thereby, the user can know how strong the gas flow is.
根據此種處理例1,於感測器30檢測錠劑T之狀態維持了特定時間以上之情形時,判斷由感測器30檢測為錠劑T之對象物並非錠劑T,而為附著於與感測器30對應之透光構件71之下表面之異物(例如粉末或廢料),且自對應於感測器30之吹氣部81吹出之氣體之流動增強。藉此,將附著於與感測器30對應之透光構件71之下表面,詳細而言,自圖3所示之貫通孔70a露出之透光構件71之下表面之異物去除,故可抑制感測器30誤檢測來到錠劑T。According to this processing example 1, when the sensor 30 detects that the state of the tablet T has been maintained for a certain period of time or longer, it is determined that the object detected by the sensor 30 as the tablet T is not the tablet T but is attached to the tablet T. Foreign matter (such as powder or waste) on the lower surface of the light-transmitting member 71 corresponding to the sensor 30 and the flow of gas blown from the gas blowing part 81 corresponding to the sensor 30 are enhanced. Thereby, the foreign matter attached to the lower surface of the light-transmitting member 71 corresponding to the sensor 30, specifically, the lower surface of the light-transmitting member 71 exposed from the through hole 70a shown in FIG. The sensor 30 falsely detects that the tablet T is coming.
此處,上述之特定時間設定為例如較錠劑T通過10錠之時間更長之時間等錠劑T連接搬送之可能性明顯較低之時間。即,可推定為並非因錠劑T連接搬送而使感測器30持續輸出「ON」,而是因異物附著於蓋70而持續輸出「ON」之時間,預先以實驗等求得,且設定該時間。Here, the above-mentioned specific time is set to a time at which the possibility of the tablets T being connected and conveyed is significantly lower, such as a time longer than the time for the tablets T to pass through 10 tablets, for example. That is, it can be estimated that the time during which the sensor 30 continues to output "ON" not because the tablet T is connected and transported, but because foreign matter adheres to the cover 70, is obtained in advance by experiments, etc., and set the time.
另,雖然步驟S2中感測器30之錠劑檢測維持了特定時間以上,步驟S3中氣體之流動變更為第2強度,但再次於步驟S2中利用感測器30持續特定時間以上進行錠劑檢測之情形時,亦可中斷處理,進行維護處理。此點於之後的處理例2~6中亦同樣。In addition, although the detection of the tablet by the sensor 30 has been maintained for a certain time or longer in step S2, the flow of the gas is changed to the second intensity in step S3, but the tablet is continued for a certain time or longer by using the sensor 30 in step S2 again. In the case of detection, the processing can also be interrupted for maintenance processing. This point is also the same in the following processing examples 2 to 6.
(處理例2) 如圖7所示,處理例2中,步驟S11中,控制部103以將自各吹氣部81分別吹出之氣體之流動設為第1強度之方式,控制各吹氣部81。其後,控制部103於步驟S12中,判斷感測器30檢測錠劑T之狀態是否維持了特定時間以上,步驟S13中,判斷藉由第1攝像部40或第2攝像部60獲得之攝像圖像內是否存在錠劑T。 (processing example 2) As shown in FIG. 7 , in processing example 2, in step S11 , the control unit 103 controls each blowing unit 81 so that the flow of the gas blown out from each blowing unit 81 is at the first intensity. Thereafter, in step S12, the control unit 103 judges whether the state of the tablet T detected by the sensor 30 has been maintained for a specific time or not, and in step S13, judges whether the image captured by the first imaging unit 40 or the second imaging unit 60 Whether there is a tablet T in the image.
步驟S12中,控制部103判斷感測器30檢測錠劑T之狀態維持了特定時間以上(步驟S12之是(Yes)),步驟S13中,判斷攝像圖像內不存在錠劑T時(步驟S13之是(Yes)),儘管由感測器30檢測為錠劑T,但因攝像圖像上不存在該錠劑T,故判斷由感測器30檢測出之對象物為附著於與感測器30對應之透光構件71之下表面之異物(例如粉末或廢料),而非錠劑T,步驟S14中,以將自各吹氣部81中對應於感測器30之吹氣部81吹出之氣體之流動自第1強度設為第2強度之方式,控制對應於感測器30之吹氣部81。其後,處理返回至步驟S12。In step S12, the control unit 103 judges that the state in which the sensor 30 detects the tablet T has been maintained for a certain period of time (Yes in step S12), and in step S13, when it is determined that there is no tablet T in the captured image (step S13). S13 (Yes)), although the sensor 30 detects it as a tablet T, because the tablet T does not exist on the captured image, it is judged that the object detected by the sensor 30 is attached and sensed. Foreign matter (such as powder or waste) on the lower surface of the light-transmitting member 71 corresponding to the detector 30, rather than the tablet T, in step S14, to blow the blowing part 81 corresponding to the sensor 30 from each blowing part 81 The blowing part 81 corresponding to the sensor 30 is controlled so that the flow of the blown gas changes from the first intensity to the second intensity. Thereafter, the process returns to step S12.
另一方面,步驟S12中,當控制部103判斷感測器30檢測錠劑T之狀態未維持特定時間以上時(步驟S12之否(No)),或,步驟S13中,當判斷攝像圖像內存在錠劑T時(步驟S13之否(No)),步驟S15中,以將自各吹氣部81分別吹出之氣體之流動維持於第1強度之方式,或,以將自各吹出部81中對應於感測器31之吹氣部81吹出之氣體之流動自第2強度返回至第1強度之方式,控制對應於感測器30之吹氣部81。其後,處理返回至步驟S12。On the other hand, in step S12, when the control unit 103 judges that the sensor 30 detects that the state of the tablet T has not been maintained for a specific time or longer (No (No) in step S12), or, in step S13, when it is judged that the captured image When there is a tablet T inside (No (No) in step S13), in step S15, the flow of the gas blown out from each blowing part 81 is maintained at the first intensity, or, by blowing out the air from each blowing part 81 The gas blowing part 81 corresponding to the sensor 30 is controlled so that the flow of the gas blown out by the blowing part 81 of the sensor 31 returns from the second intensity to the first intensity. Thereafter, the process returns to step S12.
根據此種處理例2,儘管感測器30檢測錠劑T之狀態維持了特定時間以上,但於藉由第1攝像部40或第2攝像部60獲得之攝像圖像內不存在錠劑T之情形時,自對應於感測器30之吹氣部81吹出之氣體之流動增強。藉此,因將附著於與感測器30對應之透光構件71之下表面,詳細而言,自圖3所示之貫通孔70a露出之透光構件71之下表面之異物去除,故可確實抑制感測器30誤檢測錠劑T之到來。According to this processing example 2, although the state of the tablet T detected by the sensor 30 has been maintained for a certain period of time or longer, the tablet T does not exist in the captured image obtained by the first imaging unit 40 or the second imaging unit 60 In this case, the flow of the gas blown from the blowing part 81 corresponding to the sensor 30 is enhanced. Thereby, the foreign matter attached to the lower surface of the light-transmitting member 71 corresponding to the sensor 30, specifically, the lower surface of the light-transmitting member 71 exposed from the through-hole 70a shown in FIG. The sensor 30 is surely suppressed from falsely detecting the arrival of the tablet T.
(處理例3) 如圖8所示,處理例3於步驟S21中,控制部103以將自各吹氣部81分別吹出之氣體之流動設為第1強度之方式,控制各吹氣部81。其後,步驟S22中,控制部103判斷是否於藉由第1攝像部40及第2攝像部60獲得之各攝像圖像之一者或兩者,看到特定張數(特定之攝像圖像張數)以上之異物。 (processing example 3) As shown in FIG. 8 , in processing example 3, in step S21 , the control unit 103 controls each blowing unit 81 so that the flow of the gas blown out from each blowing unit 81 is at the first intensity. Thereafter, in step S22, the control unit 103 judges whether a specific number of images (specific captured images) are seen in one or both of the captured images obtained by the first imaging unit 40 and the second imaging unit 60. Number of sheets) above the foreign body.
步驟S22中,控制部103判斷於各攝像圖像之一者或兩者看到特定張數以上之異物時(步驟S22之是(Yes)),步驟S23中,以將自與取得看到特定張數以上異物之攝像圖像之攝像部(第1攝像部40及第2攝像部60之一者或兩者)對應之吹氣部81吹出之氣體之流動自第1強度設為第2強度之方式,控制相應之吹氣部81。其後,處理返回至步驟S22。In step S22, when the control unit 103 judges that one or both of the captured images have seen more than a certain number of foreign objects (Yes (Yes) in step S22), in step S23, the specified The flow of gas blown by the blowing unit 81 corresponding to the imaging unit (either one or both of the first imaging unit 40 and the second imaging unit 60) of the captured images of more than one foreign object is changed from the first intensity to the second intensity. In this way, the corresponding blowing part 81 is controlled. Thereafter, the process returns to step S22.
另一方面,步驟S22中,當控制部103判斷於各攝像圖像之一者或兩者上未看到特定張數以上之異物時(步驟S22之否(No)),步驟S24中,以將自各吹氣部81分別吹出之氣體之流動維持於第1強度之方式,或,將自與取得看到特定張數以上異物之攝像圖像之攝像部對應之吹氣部81吹出之氣體的流動自第2強度返回至第1強度之方式,控制相應之吹氣部81。其後,處理返回至步驟S22。On the other hand, in step S22, when the control unit 103 judges that foreign objects exceeding a certain number of sheets are not seen on one or both of the captured images (No (No) in step S22), in step S24, the The method of maintaining the flow of the gas blown out from each blowing part 81 at the first intensity, or the flow of the gas blown out from the blowing part 81 corresponding to the imaging part that acquires the captured image of a specific number or more of foreign objects. The way the flow returns from the second intensity to the first intensity controls the corresponding air blowing part 81 . Thereafter, the process returns to step S22.
根據此種處理例3,於藉由第1攝像部40及第2攝像部60分別獲得之各攝像圖像之一者或兩者看到特定張數以上之異物之情形時,自與取得看到特定張數以上之異物之攝像圖像的攝像部(第1攝像部40及第2攝像部60之一者或兩者)對應之吹氣部81吹出之氣體的流動增強。即,當攝像圖像中同一位置上看到特定張數以上之異物附著時,判斷該異物為附著於蓋部70之廢料,而非附著於錠劑T之廢料,且自相應之吹氣部81吹出之氣體之流動增強。藉此,因將附著於第1攝像部40所對之透光構件71或第2攝像部60所對之透光構件72之下表面,詳細而言,自圖3所示之各貫通孔70b、70d露出之各透光構件71、72之下表面之異物去除,故可抑制第1攝像部40或第2攝像部60等攝像部拍攝附著於透光構件71、72之下表面之異物而誤檢測錠劑T。According to this processing example 3, when one or both of the captured images obtained by the first imaging unit 40 and the second imaging unit 60 see a specific number of foreign objects, the self-obtained The flow of gas blown by the gas blowing unit 81 corresponding to the imaging unit (either one or both of the first imaging unit 40 and the second imaging unit 60 ) of the captured image of the foreign matter of a certain number or more is enhanced. That is, when more than a certain number of foreign matter is seen attached to the same position in the captured image, it is judged that the foreign matter is waste material attached to the cover portion 70 rather than waste material attached to the tablet T, and the foreign matter is blown from the corresponding air blowing portion. 81 The flow of the blown gas is enhanced. Thereby, since it will be attached to the lower surface of the light-transmitting member 71 facing the first imaging unit 40 or the lower surface of the light-transmitting member 72 facing the second imaging unit 60, specifically, from each through-hole 70b shown in FIG. , 70d to remove the foreign matter on the lower surface of each light-transmitting member 71, 72 exposed, so it can prevent the first imaging unit 40 or the second imaging unit 60 from photographing the foreign matter attached to the lower surface of the light-transmitting member 71, 72. False detection of lozenge T.
此處,特定張數設定為由同一攝像部拍攝不同錠劑T獲得之複數個攝像圖像之張數。例如,由第1攝像部40依序拍攝搬送之複數個錠劑T之5個攝像圖像中,於同一位置(同一範圍內)看到異物之情形時,判斷存在於攝像圖像之異物為附著於蓋部70之下表面,而非附著於錠劑T之異物。由第1攝像部40與第2攝像部60拍攝同一錠劑,於該等2個攝像圖像之同一位置看到異物之情形時,異物為附著於錠劑T者之可能性較高。另一方面,拍攝不同錠劑T之攝像圖像中,看到特定張數以上之異物,藉此可推測異物附著於蓋部70。Here, the specific number is set as the number of a plurality of captured images obtained by capturing different tablets T by the same imaging unit. For example, in the case where a foreign object is seen at the same position (in the same range) in five captured images of a plurality of tablets T that are sequentially captured by the first imaging unit 40, it is judged that the foreign material present in the captured image is Foreign matter attached to the lower surface of the lid 70 rather than attached to the tablet T. When the same tablet is photographed by the first imaging unit 40 and the second imaging unit 60 , and foreign matter is seen at the same position of the two captured images, it is highly likely that the foreign matter is attached to the tablet T. On the other hand, in the photographed images of different tablets T, foreign matter is seen in a certain number or more, and it can be presumed that the foreign matter is attached to the cover portion 70 .
另,雖判斷是否於攝像圖像上看到特定張數以上之異物,但亦可使用用以獲得特定張數之攝像圖像之時間即特定時間,取代特定張數。例如,於搬送帶21上排列成一行之錠劑T之間隔為不規則而非特定之情形時,期望使用特定張數。另一方面,於搬送帶21上排列成一行之錠劑T之間隔特定之情形時,使用特定張數或特定時間。In addition, although it is judged whether or not more than a specific number of foreign objects are seen on the captured images, the time for obtaining the specific number of captured images, that is, the specific time may be used instead of the specific number. For example, when the intervals between the tablets T arranged in a row on the conveyor belt 21 are irregular and not specified, it is desirable to use a specific number. On the other hand, when the interval between the tablets T arranged in a row on the conveyor belt 21 is specified, a specified number of sheets or a specified time are used.
(處理例4) 如圖9所示,處理例4基本上為與處理例3相同之處理流程,但處理例4中,取代處理例3之步驟S22(參照圖8),步驟S32中,控制部103判斷於由第1攝像部40及第2攝像部60獲得之各攝像圖像之一者或兩者中,是否於不存在錠劑T之位置(攝像圖像上不存在錠劑T之區域)看到特定張數以上之異物。其後之處理流程與處理例3同樣。 (processing example 4) As shown in FIG. 9 , processing example 4 is basically the same processing flow as processing example 3, but in processing example 4, instead of step S22 (see FIG. 8 ) in processing example 3, in step S32, the control unit 103 determines that the In one or both of the captured images obtained by the first imaging unit 40 and the second imaging unit 60, is it possible to see a specific area at a position where no tablet T exists (an area where no tablet T exists on the captured image)? Foreign objects with more than one sheet. The subsequent processing flow is the same as that of processing example 3.
根據此種處理例4,藉由第1攝像部40及第2攝像部60分別獲得之各攝像圖像之一者或兩者中,於不存在錠劑T之位置看到異物,再者,自與取得看到特定張數以上之該異物之攝像圖像之攝像部(第1攝像部40及第2攝像部60之一者或兩者)對應之吹氣部81吹出之氣體之流動增強。即,當於攝像圖像中不存在錠劑T之位置上看到特定張數(特定時間)以上之異物附著時,判斷該異物為附著於蓋部70之粉末或廢料,且判斷第1強度之吹氣下無法去除異物,自相應之吹氣部81吹出之氣體之流動增強。藉此,因將附著於第1攝像部40所對之透光構件71或第2攝像部60所對之透光構件72之下表面,詳細而言,自圖3所示之各貫通孔70b、70d露出之各透光構件71、72之下表面之異物去除,故可抑制第1攝像部40或第2攝像部60等攝像部拍攝附著於透光構件71、72之下表面之異物而誤檢測錠劑T。According to this processing example 4, in one or both of the captured images respectively obtained by the first imaging unit 40 and the second imaging unit 60, a foreign object is seen at a position where the tablet T does not exist. Furthermore, The flow of the gas blown from the blowing unit 81 corresponding to the imaging unit (either one or both of the first imaging unit 40 and the second imaging unit 60) that acquires the captured image of the foreign object in a certain number or more is enhanced. . That is, when a specific number of sheets (at a specific time) or more of foreign matter adhered to a position where there is no tablet T is seen in the captured image, it is judged that the foreign matter is powder or waste adhering to the cover portion 70, and the first intensity is judged. The foreign matter cannot be removed under the air blowing, and the flow of the gas blown out from the corresponding air blowing part 81 is enhanced. Thereby, since it will be attached to the lower surface of the light-transmitting member 71 facing the first imaging unit 40 or the lower surface of the light-transmitting member 72 facing the second imaging unit 60, specifically, from each through-hole 70b shown in FIG. , 70d to remove the foreign matter on the lower surface of each light-transmitting member 71, 72 exposed, so it can prevent the first imaging unit 40 or the second imaging unit 60 from photographing the foreign matter attached to the lower surface of the light-transmitting member 71, 72. False detection of lozenge T.
(處理例5) 如圖10所示,處理例5與處理例3之處理流程基本相同,但處理例5中,取代處理例3之步驟S22(參照圖8),於步驟S42中,控制部103判斷於由第1攝像部40及第2攝像部60獲得之各攝像圖像之兩者(二個攝像圖像)中,異物之有無或異物之位置是否不一致。其後之處理流程與處理例3同樣,但步驟S23中,控制部103以將自對應於第1攝像部40及第2攝像部60之兩者之各吹氣部81吹出之氣體之流動自第1強度設為第2強度之方式,控制相應之各吹氣部81。 (processing example 5) As shown in FIG. 10 , the processing flow of processing example 5 and processing example 3 is basically the same, but in processing example 5, instead of step S22 (refer to FIG. 8 ) of processing example 3, in step S42, the control unit 103 determines that the In both of the captured images obtained by the first imaging unit 40 and the second imaging unit 60 (two captured images), whether the presence or absence of a foreign object or the position of a foreign object is inconsistent. The subsequent processing flow is the same as that of the processing example 3, but in step S23, the control part 103 controls the flow of the gas blown out from each blowing part 81 corresponding to both of the first imaging part 40 and the second imaging part 60. The first intensity is set as the second intensity, and the corresponding air blowing parts 81 are controlled.
根據此種處理例5,由第1攝像部40及第2攝像部60分別獲得之各攝像圖像之兩者中,異物之有無或異物之位置不一致之情形時,自對應於第1攝像部40及第2攝像部60之兩者之各吹氣部81分別吹出之氣體之流動增強。即,對於同一錠劑T,以第1攝像部40拍攝之圖像與以第2攝像部69拍攝之圖像中,異物之有無或位置不一致之情形時,判斷該異物為附著於蓋部70之粉末或廢料,而非附著於錠劑T之粉末或廢料,自相應之各吹氣部81吹出之氣體之流動增強。藉此,因將附著於第1攝像部40所對之透光構件71或第2攝像部60所對之透光構件72之下表面,詳細而言,自圖3所示之各貫通孔70b、70d露出之各透光構件71、72之下表面之異物去除,故可抑制第1攝像部40或第2攝像部60等攝像部拍攝附著於透光構件71、72之下表面之異物而誤檢測錠劑T。According to this processing example 5, when the presence or absence of a foreign object or the position of a foreign object is inconsistent with each of the captured images respectively obtained by the first imaging unit 40 and the second imaging unit 60, the image corresponding to the first imaging unit The flow of the gas blown out by each blowing part 81 of both the 40 and the second imaging part 60 is strengthened. That is, for the same tablet T, when the image captured by the first imaging unit 40 and the image captured by the second imaging unit 69 differ in the presence or absence or position of foreign matter, it is judged that the foreign matter is attached to the cover portion 70. The powder or waste material, rather than the powder or waste material attached to the tablet T, the flow of the gas blown from the respective blowing parts 81 is enhanced. Thereby, since it will be attached to the lower surface of the light-transmitting member 71 facing the first imaging unit 40 or the lower surface of the light-transmitting member 72 facing the second imaging unit 60, specifically, from each through-hole 70b shown in FIG. , 70d to remove the foreign matter on the lower surface of each light-transmitting member 71, 72 exposed, so it can prevent the first imaging unit 40 or the second imaging unit 60 from photographing the foreign matter attached to the lower surface of the light-transmitting member 71, 72. False detection of lozenge T.
(處理例6) 如圖11所示,處理例6與處理例3之處理流程基本相同,但處理例6中,取代處理例3之步驟S22(參照圖8),於步驟S52中,控制部103判斷是否為噴墨頭51之維護中。其後之處理流程與處理例3同樣,但步驟S23中,控制部103以將自所有吹氣部81吹出之氣體之流動自第1強度設為第2強度之方式,控制相應之所有之各吹氣部81。 (processing example 6) As shown in FIG. 11 , the processing flow of processing example 6 is basically the same as that of processing example 3, but in processing example 6, instead of step S22 (refer to FIG. 8 ) of processing example 3, in step S52, the control unit 103 determines whether the The ink head 51 is being maintained. The subsequent processing flow is the same as that of Processing Example 3, but in step S23, the control unit 103 controls the flow of the gas blown out from all the blowing units 81 from the first intensity to the second intensity, and controls all corresponding ones. blowing part 81 .
根據此種處理例6,噴墨頭51之維護中之情形時,自所有吹氣部81分別吹出之氣體之流動增強。藉此,於維護中,將附著於感測器30、相對於第1攝像部40及第2攝像部60之各透光構件71、72之下表面,詳細而言,自圖3所示之各貫通孔70a、70b、70d露出之各透光構件71、72之下表面之異物去除,故可抑制感測器30檢測附著於透光構件71之下表面之異物而誤檢測錠劑T,又,抑制第1攝像部40或第2攝像部60等攝像部拍攝附著於透光構件71、72之下表面之異物而誤檢測錠劑T。According to this processing example 6, when the inkjet head 51 is being maintained, the flows of the gases blown from all the blowing parts 81 are strengthened. In this way, during maintenance, the lower surfaces of the light-transmitting members 71 and 72 attached to the sensor 30 and opposite to the first imaging unit 40 and the second imaging unit 60, in detail, from the one shown in FIG. 3 The foreign matter on the lower surface of each light-transmitting member 71, 72 exposed by each through-hole 70a, 70b, 70d is removed, so it can prevent the sensor 30 from detecting the foreign matter attached to the lower surface of the light-transmitting member 71 and falsely detecting the tablet T. In addition, it is possible to prevent false detection of tablets T caused by imaging units such as the first imaging unit 40 and the second imaging unit 60 imaging foreign objects adhering to the lower surfaces of the light-transmitting members 71 and 72 .
另,是否為噴墨頭51之維護中,例如可於感測器30、第1攝像部40、第2攝像部60之錠劑T之檢測超出特定時間仍未完成時,判斷為維護中。或,控制裝置100亦可檢知經作業者選擇為「維護模式」,而判斷為維護中。In addition, whether the inkjet head 51 is being maintained can be judged as being under maintenance when, for example, the detection of the tablet T by the sensor 30 , the first imaging unit 40 , and the second imaging unit 60 has not been completed for a specified period of time. Alternatively, the control device 100 may also detect that the operator selects the "maintenance mode", and determine that the maintenance is in progress.
通常,於維護時於搬送帶21上不存在錠劑T,錠劑T之姿勢亦不因自各吹氣部81吹出之氣體之流動而變化,故亦可產生強烈氣流。又,維護噴墨頭51時,有時藉由設置於維護部之吸引部進行液滴之吸引,因此有時會產生空氣之流動,使附著於噴墨頭51之粉末或廢料等飛揚,附著於蓋部70,但藉由加強自各吹氣部81吹出之氣體之流動,可抑制飛揚之粉末或廢料等附著於蓋部70之下表面。又,即使飛揚之粉末或廢料等附著於蓋部70之下表面,亦可去除該粉末或廢料等。Usually, there is no tablet T on the conveyor belt 21 during maintenance, and the posture of the tablet T is not changed by the flow of gas blown from each blowing part 81, so strong air flow can also be generated. Also, when maintaining the inkjet head 51, the suction of the liquid droplets is sometimes carried out by the suction part provided in the maintenance part, so sometimes the flow of air is generated, and the powder or waste materials adhering to the inkjet head 51 are flying and adhered to the inkjet head 51. In the cover part 70 , by strengthening the flow of the gas blown from each blowing part 81 , it is possible to suppress flying powder or waste from adhering to the lower surface of the cover part 70 . Also, even if flying powder, waste, etc. adhere to the lower surface of the cover portion 70, the powder, waste, etc. can be removed.
如上說明,根據第1實施形態,錠劑印刷裝置1具備:檢測部(例如感測器30、第1攝像部40或第2攝像部60),其檢測藉由搬送帶21搬送之錠劑T;噴墨頭51,其對由檢測部檢測出之錠劑T進行印刷;蓋部70,其覆蓋檢測部;吹氣部81,其對蓋部70之搬送帶21側之面,沿俯視時與錠劑T之搬送方向H1水平交叉之方向吹附氣體;及控制部103,其控制吹氣部81。藉此,由吹氣部81,將氣體吹附至蓋部70之下表面,將附著於蓋部70之下表面之異物(例如粉末或廢料)去除,因而可抑制檢測部檢測出附著於蓋部70之下表面之異物而誤檢測錠劑T。因此,可抑制因異物附著所致之誤檢測,效率良好地對錠劑T進行印刷。As described above, according to the first embodiment, the tablet printing apparatus 1 includes a detection unit (such as the sensor 30, the first imaging unit 40, or the second imaging unit 60) that detects the tablet T conveyed by the conveyor belt 21. Inkjet head 51, which prints the tablet T detected by the detection part; cover part 70, which covers the detection part; air blowing part 81, its surface on the conveyor belt 21 side of cover part 70, when viewed from above Gas is blown in a direction horizontally intersecting with the conveying direction H1 of the tablet T; and the control unit 103 controls the blowing unit 81 . Thereby, the gas blowing part 81 blows the gas onto the lower surface of the cover part 70, and the foreign matter (such as powder or waste) adhering to the lower surface of the cover part 70 is removed. The foreign matter on the lower surface of the part 70 may cause false detection of the tablet T. Therefore, it is possible to suppress erroneous detection due to adhesion of foreign matter, and to efficiently print on the tablet T.
<第2實施形態> 就第2實施形態,參照圖12進行說明。 <Second Embodiment> A second embodiment will be described with reference to FIG. 12 .
第2實施形態中,如圖12所示,錠劑T以二行搬送。該情形時,供給部10將錠劑T以成二行之方式對搬送帶21供給。圖12之例中,錠劑T以二行搬送,但並非限定者。錠劑T以二行搬送之情形時,感測器30、第1攝像部40及第2攝像部60按各行設置。另,噴墨頭51以各行共通之方式設置,但並非限定於此,亦可按各行設置。In the second embodiment, as shown in FIG. 12 , the tablets T are conveyed in two rows. In this case, the supply unit 10 supplies the tablets T to the conveyor belt 21 in two rows. In the example of Fig. 12, the tablets T are conveyed in two rows, but the present invention is not limited thereto. When the tablets T are conveyed in two rows, the sensor 30, the first imaging unit 40, and the second imaging unit 60 are installed in each row. In addition, although the inkjet head 51 is provided so that each row may be common, it is not limited to this, You may arrange for each row.
吹氣部81係針對複數個感測器30、複數個第1攝像部40及複數個第2攝像部60之各者設置。圖12之例中,吹氣部81設有六個,於搬送方向H1排列二行。每行之吹氣部81避開各行之內側,向外側吹出氣體。詳細而言,各吹氣部81以俯視時複數個吸引孔21a位於排列二行之行間之方式,設置於蓋部70之下表面。該等吹氣部81分別沿蓋部70之下表面,向蓋部70與搬送帶21間之空間之外側,互相朝相反方向吹出氣體。The air blowing unit 81 is provided for each of the plurality of sensors 30 , the plurality of first imaging units 40 , and the plurality of second imaging units 60 . In the example of FIG. 12, six air blowing parts 81 are provided, and are arranged in two rows in the conveyance direction H1. The gas blowing part 81 of each row avoids the inner side of each row, and blows gas outward. In detail, each air blowing part 81 is provided in the lower surface of the cover part 70 so that several suction holes 21a may be located between the rows arranged in two rows in planar view. The gas blowing parts 81 blow out gas in opposite directions to the outside of the space between the cover part 70 and the conveyor belt 21 along the lower surface of the cover part 70 .
另,以三行以上之複數行搬送之情形時,各吹氣部81分別向外側吹出氣體。此時,與位於內側之搬送行對應之吹氣部81向位於外側之搬送行之錠劑T吹出氣體,藉由向外側(即,相鄰之搬送行較少之方向)吹出氣體,可將自吹氣部81吹出之氣體對錠劑T之姿勢造成影響之風險設為最小。In addition, in the case of conveying in a plurality of lines of three or more, each air blowing part 81 blows air to the outside respectively. At this time, the air blowing unit 81 corresponding to the inner conveying row blows air to the tablet T located on the outer conveying row. The risk that the air blown from the air blowing part 81 affects the posture of the tablet T is minimized.
根據此種構成,氣體之吹出方向為俯視時與搬送方向H1水平交叉之方向,即不朝向相鄰之搬送行之方向,即朝向相鄰之搬送行之外側之方向。藉此,至少僅於通過吹氣部81之下時,錠劑T暴露於氣流中,因而抑制氣體吹出之氣流對錠劑T之姿勢造成影響,故可效率良好地對錠劑T進行印刷。又,由於抑制自吹氣部81吹出之氣體對噴墨頭51之印刷造成影響,故可效率良好地對錠劑T進行印刷。According to this configuration, the blowing direction of the gas is a direction horizontally intersecting with the conveying direction H1 in plan view, that is, a direction not toward the adjacent conveying row, that is, a direction toward the outside of the adjacent conveying row. Thereby, the tablet T is exposed to the air flow at least only when it passes under the air blowing part 81, and the influence of the air flow of the blown gas on the posture of the tablet T is suppressed, so that the tablet T can be printed efficiently. Moreover, since the influence of the gas blown from the air blowing part 81 on the printing of the inkjet head 51 is suppressed, printing on the tablet T can be performed efficiently.
另,排列於搬送方向H1之各吹氣部81各自之氣體吹出方向相同,但並非限定者,亦可不同。又,由於各吹氣部81各自之氣體吹出方向為俯視時與搬送方向H1水平交叉之方向,故可為俯視時朝搬送方向H之上游側傾斜之方向,亦可為俯視時朝搬送方向H之下游側傾斜之方向,但為抑制氣體向噴墨頭51側之吹附,較佳為朝與噴墨頭51側相反側傾斜之方向。例如,與感測器30及第1攝像部40對應之各吹氣部81各自之氣體之吹出方向期望為俯視時朝搬送方向H1之上游側傾斜之方向,與第2攝像部60對應之吹氣部81之氣體吹出方向期望為俯視時朝搬送方向H1之下游側傾斜之方向。In addition, although the respective gas blowing directions of the air blowing parts 81 arranged in the conveyance direction H1 are the same, it is not limited thereto and may be different. Also, since the blowing direction of each gas blowing portion 81 is a direction horizontally intersecting with the conveying direction H1 in a plan view, it may be a direction inclined toward the upstream side of the conveying direction H in a plan view, or may be directed toward the conveying direction H in a plan view. The downstream side is inclined in a direction, but in order to suppress blowing of the gas to the inkjet head 51 side, it is preferably inclined in a direction opposite to the inkjet head 51 side. For example, the gas blowing direction of each gas blowing unit 81 corresponding to the sensor 30 and the first imaging unit 40 is expected to be a direction inclined toward the upstream side of the conveying direction H1 in plan view, and the gas blowing direction corresponding to the second imaging unit 60 The gas blowing direction of the gas part 81 is desirably a direction inclined toward the downstream side of the conveyance direction H1 in planar view.
如上說明,根據第2實施形態,可獲得與第1實施形態相同之效果。又,以複數行搬送錠劑T之情形時,亦抑制氣體吹出之氣流對錠劑T之姿勢或噴墨頭51之印刷造成影響,故可效率良好地對錠劑T進行印刷。As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained. Also, when the tablets T are conveyed in multiple lines, the influence of the air flow of the blown gas on the posture of the tablets T or the printing of the inkjet head 51 is suppressed, so that the tablets T can be printed efficiently.
<其他實施形態> 上述之說明中,使用一實施形態之錠劑印刷裝置1(錠劑印刷方法)對錠劑T進行印刷,其亦可換稱為,使用一實施形態之錠劑印刷裝置1(錠劑印刷方法)對錠劑T進行印刷,製造已印刷之錠劑T。即,可將錠劑印刷裝置1換稱為錠劑製造裝置,將錠劑印刷方法換稱為錠劑製造方法。 <Other Embodiments> In the above description, the tablet T is printed using the tablet printing device 1 (tablet printing method) of one embodiment, which can also be referred to as using the tablet printing device 1 (tablet printing method) of one embodiment ) to print the tablet T to manufacture the printed tablet T.
