In this way, appearance determination portion 11 and press quality determination unit 13 constitute defective products determination unit, the defective products determination unit base In the image that camera 51~55 takes, the object tablet that should be recycled in tablet 9 is determined.
First row, which goes out processing unit 14, to be had based on the first press quality data D131 and the second press quality data D132, is made Printing defective product recycling releases the absorption with the tablet 9 of open defect with mechanism 611 of supplying gas.In addition, the first discharge Processing unit 14, which also has, is based on the first appearance data D111 and the second appearance data D112, makes bad order product recycling air feeder Structure 621 releases the function of having the absorption for printing undesirable tablet 9.
After step S107, first row goes out processing unit 14 based on the first press quality inputted from press quality determination unit 13 Data D131 and the second press quality data D132 determines the adsorption section 330 for maintaining the printing defective products that should be recycled.Then, Based on the definitive result, first row, which goes out processing unit 14, makes printing defective product recycling use the releasing of mechanism 611 of supplying gas bad as printing The absorption of the tablet 9 of product.The recycling (step S108) of printing defective products is carried out into printing defective product recycling case 612 as a result,.
Then, first row go out processing unit 14 based on the first appearance data D111 and second inputted from appearance determination portion 11 outside Data D112 is seen, determines the adsorption section 330 for maintaining the bad order product that should be recycled.Then, the definitive result, first row are based on Processing unit 14 makes the recycling of bad order product that mechanism 621 of supplying gas be used to release the absorption as the tablet 9 of bad order product out.As a result, Bad order product (step S109) is recycled into appearance defective product recycling case 622.
After step S109, discharge sensor 63 is under printing defective product recycling portion 61 and bad order product recoverer 62 Side is swum, detects whether each adsorption section 330 maintains tablet 9.Remain the detection knot that determination unit 15 is detected based on discharge sensor 63 Fruit determines residual tablet.Residual tablet, which refers to, should be printed what defective product recycling portion 61 and bad order product recoverer 62 recycled The tablet 9 for remaining in adsorption section 330 in object tablet (printing defective products and bad order product).Confirmation printing is bad as a result, Whether product recoverer 61 and bad order product recoverer 62 are normally discharged (step S110).
Second row goes out judgement of the processing unit 16 based on residual determination unit 15 as a result, recycling is released with mechanism 641 of supplying gas after making Including maintaining absorption of a part of adsorption section 330 for remaining the adsorption section 330 of tablet to tablet 9.Recycling bins backward as a result, Recycling residual tablet (step S111) in 642.
In this way, discharge sensor 63 and rear recoverer 64 that tablet printing equipment 1 has can be further improved defective products Recovery efficiency.Therefore, the reliability of the quality of the tablet 9 as drug can be further increased.
In present embodiment, rear recycling mechanism 641 of supplying gas makes positive pressure in the position of conveyance direction and keeps remaining The identical all adsorption sections 330 in the adsorption section 330 of tablet release the absorption of tablet 9.That is, rear recoverer 64 makes multiple adsorption sections In 330 includes the absorption of the releasing of all adsorption sections 330 tablet 9 on the row for maintain the adsorption section 330 of residual tablet.
In this way, the case where printing defective product recycling portion 61 and bad order product recoverer 62 is not discharged normally Under, not only recycling residual tablet, return packet receiving include residual tablet row on all tablets, it is bad so as to further increase The recovery efficiency of product.Therefore, the reliability of the quality of tablet 9 can be further increased.
In addition, the rear recycling mechanism 641 of supplying gas for supplying gas mechanism as second acts on adsorption section in present embodiment The pressure of 330 positive pressure is higher than printing defective product recycling mechanism 611 and the bad order product of supplying gas for supplying gas mechanism as first Recycling acts on the pressure of the positive pressure of adsorption section 330 with mechanism 621 of supplying gas.
It is generally acknowledged that the state of the adsorption section 330 of the shape of residual tablet, holding residual tablet is different from being usually to generate Printing defective product recycling mechanism 611 and the bad order product recycling bad reason of the generation discharge of mechanism 621 of supplying gas of supplying gas.Cause This, in order to which rear recycling is more reliably discharged with mechanism 641 of supplying gas, recycles the residual tablet, it is preferable that supplied gas like this by second The pressure value for the positive pressure that mechanism is generated in adsorption section is greater than the pressure value for supplying gas positive pressure that mechanism is generated in adsorption section by first.
In addition, the rear recycling for supplying gas mechanism as second acts on mechanism 641 of supplying gas the pressure of the positive pressure of adsorption section 330 The printing defective product recycling for supplying gas mechanism as first can also be equal to be recycled with supply gas mechanism 611 and bad order product with supplying gas Mechanism 621 acts on the pressure of the positive pressure of adsorption section 330.
2. second embodiment
Next, explanation has used the process of the printing process of the tablet printing equipment 1 of second embodiment.Second implements The apparatus structure of the tablet printing equipment 1 of mode and the tablet printing equipment 1 of first embodiment are identical.Fig. 8 is to show second The flow chart of the process of the printing process of the tablet printing equipment 1 of embodiment.
In the printing process of second embodiment, successively carry out tablet 9 the second face visual examination (step S201), The visual examination (step S202) in the first face, to the print inspection (step of the printing process (step S203) in the first face, the first face S204), the visual examination (step S205) in the second face, the printing of the printing process (step S206) in the second face, the second face is examined It looks into (step S207), print the recycling (step S208) of defective products and the recycling (step S209) of bad order product.
Due to the print in the step S201~step S209 and first embodiment of the printing process in second embodiment Step S101~step S109 of dataller's sequence is identical, therefore the description thereof will be omitted.
Carrying out step S208, after the defective product recycling in 209, inspection of the residual determination unit 15 based on discharge sensor 63 It surveys as a result, determining residual tablet.Residual tablet refers to that should be printed defective product recycling portion 61 and bad order product recoverer 62 returns The tablet for remaining in adsorption section 330 in the object tablet (printing defective products and bad order product) of receipts.That is, it is judged that printing is bad Whether product recoverer 61 and bad order product recoverer 62 are normally discharged (step S210).
In step S210, it is judged as printing defective product recycling portion 61 and bad order product recoverer in residual determination unit 15 In the case that 62 are normally discharged, second row goes out judgement of the processing unit 16 based on residual determination unit 15 as a result, returning after making Receive the recycling (step S211) that sample tablet is carried out with mechanism 641 of supplying gas.Specifically, second row goes out processing unit 16 with defined Interval (for example, every 10 row adsorption section 330 a piece of interval) makes positive pressure in the adsorption section for keeping the tablet 9 as non-defective unit 330, to release the absorption of the adsorption section 330 to tablet 9.Non-defective unit tablet 9 is recycled to rear recycling bins as sample tablet as a result, 642。
