As shown in Figure 20, in recycle object determination processing, first, in step S101, according to from check device T1, D, A and input whether the information of qualified judging result, determine inspection item X1~X9 of each tablet 5 and piece part, Y1, Whether Z1, Z2 are qualified (referring to Fig.1 9).
Then, in step S102, according to for each inspection item X1~X9 for each tablet 5 and piece part specified, Y1, Whether Z1, Z2 are qualified, and whether judgement piece predetermined position is qualified.In the present embodiment, in each tablet 5 and piece part, pass through inspection It looks at least one of project X1~X9, Y1, Z1, Z2 and judges underproof occasion (step S102：It is no), judge piece reservations Position is qualification, goes to step S103.On the other hand, in each tablet 5 and piece part, by whole inspection item X1~X9, Y1, Z1, Z2 are without occasion (the step S102 of unqualified judgement：It is), judgement piece predetermined position is qualified, terminates present treatment.
In step S103, the inspection item to being judged as defective work whether be inspection item Z1 or inspection item Z2 into Row judges.Herein, in occasion (the step S103 for being determined as defective work by inspection item Z1 or inspection item Z2：It is), Terminate present treatment.That is, in the present embodiment, being determined as not by the inspection item of " on piece hair " or " on piece foreign matter " The occasion of certified products, sets in the following manner, and which is：Even if being determined as the whole of the piece predetermined position of defective work Tablet 5 is certified products, the also recycling without the tablet 5 from piece predetermined position.It considers hair, foreign matter and any tablet The possibility of 5 contacts.
On the other hand, occasion (the step S103 in the two by Z1, Z2 without judging defective work：It is no), it goes to Step S104, according to it is fixed whether qualified information, determine the tablet 5 for constituting recycle object.In the present embodiment, will It is determined as that qualified target is determined as recycle object by each inspection item X1~X9 in each tablet 5 of piece predetermined position. For example, being only judged as reason with the defective work of the tablet 5 represented by tablet J2, having carried out negative in step S102 sentences Fixed occasion determines and regard the tablet 5 other than the tablet 5 represented by tablet J2 as recycle object.In addition, for example, only Piece part is determined as defective work this point as reason using inspection item Y1, the field of negative judgement has been carried out in step S102 It closes, since tablet 5 is without abnormal, therefore whole tablets 5 is determined as recycle object.In addition, by fixed recycle object Information is stored in together with the serial number of piece predetermined position in above-mentioned RAM, terminates present treatment.
Referring to Figure 21, to the control process (pick device control process) of the switching solenoid valve 235 of control device 60 It illustrates.In addition, the processing repeatedly carries out (than ms in full) at regular intervals.
In pick device control process, first, in step S201, it is Zone switched whether judgement suction portion 231A reaches P3.The judgement is carried out according to the information from the above-mentioned encoder being set on rotating cylinder 231.It is that step S201 is determined as The occasion for being goes to step S202.On the other hand, it is that step S201 is determined as no occasion, terminates present treatment.
In step S202, in opposite shape when judgement reaches suction region P5 positioned at the suction portion 231A of Zone switched P3 Whether the tablet 5 of state constitutes recycle object.The judgement is carried out according to following information, which, which refers to, is stored in above-mentioned RAM The output signal from above-mentioned encoder with the relevant information of recycle object, with the upwards of movement for holding container film 3.Separately Outside, which is directed to and is carried out positioned at each suction portion 231A of Zone switched P3.Also with regard to following step S203~ The processing of S208 also carries out each suction portion 231A as object.It is the occasion that step S202 is judged to being, goes to step Rapid S203.On the other hand, it is that step S202 is determined as no occasion, goes to step S206.
In step S203, judge：On the suction portion 231A of suction tablet 5, be connected to suction hole 231B with switching The corresponding openings of spatial portion S3 identify whether to be on states.Open mark is arranged more corresponding to each switching spatial portion S3 A, which is identified as the judgement information that the state for being on to the occasion of the state of atmosphere opening is in switching spatial portion S3. In open occasion (the step S203 for being identified as off：It is no), that is, negative pressure feeding is being maintained to the occasion of switching spatial portion S3 Terminate present treatment under conditions of the state.As a result, answer the suction portion 231A of suction tablet 5 maintain can suction state, such as Fruit reaches suction position P5, then suction tablet 5.
On the other hand, in open occasion (the step S203 for being identified as on：It is), that is, it is opened to air in switching spatial portion S3 The occasion put goes to step S204, switching solenoid valve 235 is controlled, for the suction hole with the suction portion 231A for answering suction tablet 5 The switching spatial portion S3 of 231B connections supplies negative pressure from vacuum pump 234.It is that can attract vacuum to be in switching spatial portion S3 as a result, Pressure air pressure below, can be by the state (state that can be supplied to negative pressure) of negative pressure feeding to suction hole 231B.As a result, should inhale Connect tablet 5 suction portion 231A be in can suction state, if reach suction position P5, start suction tablet 5.In next step Rapid S205, it is open to be identified as off, terminate present treatment.
As described above, it is that the occasion of recycle object is different from tablet 5, is not the occasion (step of recycle object in tablet 5 S202：It is no), step S206 is gone to, is judged：Should be at can not be on the suction portion 231A of suction state, with its suction hole 231B The corresponding openings of switching spatial portion S3 of connection identify whether as on.In open occasion (the step S206 for being identified as on：It is), That is, switching spatial portion S3 maintains the state and terminates present treatment to the occasion of atmosphere opening.As a result, with switching space The air pressure of the suction hole 231B of portion S3 connections increases in moment, when suction portion 231A reaches suction position P5, suction hole 231B's Air pressure be more than can suction vacuum pressure air pressure (be usually atmospheric pressure).In addition, tablet 5 does not have suction in suction portion 231A On.
On the other hand, in open occasion (the step S206 for being identified as off：It is no), go to step S207, control switching electromagnetism Valve 235, by with do not answer the switching spatial portion S3 that the suction hole 231B of the suction portion 231A of suction tablet 5 is connected to atmosphere opening. It is in the state (atmosphere opening state) to atmosphere opening with the suction hole 231B that are connected to of switching spatial portion S3 as a result,.Its result It is that the air pressure of suction hole 231B increases, in suction position P5, tablet 5 is without suction on the 231A of suction portion.In step S207 Afterwards, make to open in step S208 and be identified as on, terminate present treatment.
As described above, according to the present embodiment, being vacuumized to suction hole 231B in advance, suction portion 231A is made to be in Negative pressure state or atmosphere opening state can be can be supplied to by being on the basis of suction state, can be switched that tablet 5 is opposite to be inhaled in advance The suction of socket part 231A and non-suction.Due to like this, suction portion 231A be in advance can suction state, therefore can be more reliably The suction for carrying out the tablet 5 based on suction portion 231A, can effectively inhibit the generation of suction mistake.
In addition, in general, make air pressure be can suction vacuum pressure suction hole 213B to atmosphere opening, make suction hole The air pressure of 213B be more than can the suction vacuum pressure required time (that is, from can suction state be switched to can not suction state institute The time needed), it shorter than can up to making the air pressure of suction hole 231B be by negative pressure feeding to the suction hole 231B under air The suction vacuum pressure required time (that is, from can not suction state be switched to can the suction state required time).Then, Suction of the time-switching tablet 5 with respect to suction portion 231A that can be shorter and non-suction.It can further be reliably prevented as a result, The generation of the suction mistake of tablet 5.
In addition, suction hole 231B under atmosphere opening state from can suction vacuum pressure the rate of rise absolute value, It is set as being more than the absolute value of the decompression rate for the suction hole 231B that can be supplied to the vacuum pump 234 under negative pressure state.That is, making suction Portion 231A from can suction state to can not suction state when suction hole 231B air pressure pace of change, more than making suction portion 231A from can not suction state to can suction state when suction hole 231B air pressure pace of change.It then, can be by suction portion 231A quickly from can suction state be switched to can not suction state.It can further be reliably prevented the hair of suction mistake as a result, It is raw.
In addition, due to can by suction portion 231A quickly from can suction state be switched to can not suction state, therefore can make open It puts at the time of be more nearly suction portion 231A to suction position P5 constantly.Can make for the 1st moment also slow as much as possible as a result, not into The supply of negative pressure of the row since the premature stage (attraction).As a result, can effectively be attracted.
In addition, in the present embodiment, make suction portion 231A from can suction state to can not suction state when necessary suction The maximum value of the variable quantity of the air pressure of pilot hole 231B is (maximum suction vacuum pressure and to eventually arrive at the pressure difference of vacuum pressure SA1), less than make suction portion 231A from can not suction state to can suction state when necessary suction hole 231B air pressure variation Amount maximum value (atmospheric pressure with it is maximum can suction vacuum pressure pressure difference SA2).It then, can be more rapidly by suction portion 231A From can suction state be switched to can not suction state.As a result, the generation of suction mistake can be further reliably prevented.
In addition, if the rotation of accompanying rotation cylinder 231, venthole 231C reaches negative pressure space portion S2, then automatically starts The prior of suction hole 231B vacuumizes, if venthole 231C reaches switching spatial portion S3, automatically maintains or release to inhale Socket part 231A's can suction state.Then, must certain position carry out it is prior vacuumize, can suction state maintenance and The switching of releasing.As a result, can further seek the generation of inhibition suction mistake, the action of the stabilization of device is sought.
