A seal means for attaching a belt-shaped cover film to the container film so as to close the pocket portion on the downstream side of the rotary drum and obtaining a blister film in which the cover film is adhered to the container film; ,

On the downstream side of the seal means, the bristle film is punched out in sheet units; punching means for obtaining a predetermined blister sheet,

An inspection means for performing a positive / negative determination on a plurality of inspection items including items related to both sides of the article, with respect to the sheet preliminarily positioned between the charging means and the rotary drum and serving as the final blister sheet 1. A breister packer comprising:

When the sheet scheduled portion determined to be defective with respect to at least one inspection item by the inspection means is a defective sheet portion,

The adsorption object determining means is configured to be able to determine, as the object to be adsorbed, the object determined to be good in the items related to both sides of the article, by the inspection means, among the articles filled in the pocket portion of the defective sheet portion Bristle wrapping machine.

According to the above-mentioned means 1, when the article is sucked, the container film is lifted up by the lift means, and the article is brought close to the sucking portion. Therefore, the article can be more reliably adsorbed by the adsorbing section, and moreover, the article can be more reliably recovered.

Further, in approaching the article with respect to the attracting portion, the rotary drum having a large weight and complicated structure is not moved up and down (moving up and down). Therefore, it is not necessary to provide a large-scale mechanism, and it is possible to reduce the cost related to the manufacturing of the apparatus, and realize more stable and higher-speed operation.

According to the above-mentioned means 1, when the article is not adsorbed, the article is separated from the adsorption section. Therefore, consumption (wear and deterioration) of the adsorption section can be effectively suppressed, and the adsorption section can be maintained in an appropriate state for a longer period of time. In addition, since the adsorption part is separated from the article, it is possible to more reliably prevent damage or contamination of the article due to the contact of the adsorption part.

Further, according to the above-mentioned means 1, at least a portion of the adsorption section which is in contact with the article can be formed of a relatively soft material. By such a constitution, it is possible to reduce the load exerted on the article at the time of adsorption, and it is possible to recover the article in a better state. On the other hand, if at least a portion of the adsorption section which is in contact with the article is formed of a relatively soft material, it is feared that consumption of the adsorption section is likely to progress, but with the means 1, such concern can be eliminated.

According to the means 2, the container film is lifted by the rotating roller which is rotatable in accordance with the conveyance of the container film. Therefore, it is possible to more reliably prevent scratches on the container film at the time of lifting, and it is possible to improve the quality of the blister sheet.

The rotating roller may be a freely rotatable driven roller that rotates with contact with the container film, or may be a driving roller that rotates in accordance with the conveyance of the container film by the power from the predetermined driving means .

According to the above-mentioned means 3, when the article is adsorbed, the load applied to the article can be further reduced by reducing (reducing) the bellows portion. As a result, the article can be recovered in a better state.

By the way, when the container film is lifted up when the article is sucked, as a result, the sucking portion and the pocket portion are brought close to each other. Therefore, it is conceivable that the adsorbed article is liable to come into contact with the pocket portion when the rotating drum rotates and comes out of the pocket portion. If the article is brought into contact with the pocket portion, there is a fear that the article is released from the adsorbing portion (separated) or the article is damaged.

In this regard, according to the means 3 described above, the article is lifted from the pocket portion by reducing the bellows portion, and in this state, the article comes out from the pocket portion. Therefore, it is possible to more reliably prevent the article from coming into contact with the pocket portion, and it is possible to effectively suppress the suction failure and the damage of the article. That is, according to the means 3, it is possible to solve the demerit that may occur due to the adoption of the means 1 or the like, which is difficult to occur when only the description of the means 3 is employed, A special action effect is exhibited.

In the means 4, for example, a center valve method is conceivable as a method for enabling each adsorption portion to be switched to the adsorption state or the non-adsorption state. The center valve system is a system in which a fixed valve having a plurality of switching spaces is provided so as to cover an axial end face (end face) of a rotary drum, and suction holes of the respective suction portions are individually . In this method, the supply and non-supply of the negative pressure to each suction hole is switched by switching the supply and non-supply of the negative pressure to the switching space portion, and further, each of the suction portions becomes the adsorption state or the non-adsorption state. In this method, each suction hole extends parallel to the axial direction of the rotary drum inside the rotary drum, and is formed so as to open at the axial end face (end face on the fixed valve side) of the rotary drum.

However, in this method, since each suction hole is provided as described above, it is necessary to make the rotary drum larger (larger diameter).

If necessary, the rotary drum and the fixed valve may be disassembled and then both may be cleaned so that there is no foreign matter such as a broken piece (piece) of the article in the suction hole or the switching space portion. However, The suction hole extends in the axial direction of the rotary drum, so it is not easy to confirm the inside thereof, and there is a possibility that it becomes difficult to confirm the remaining foreign matter after cleaning.

In this respect, according to the means 4, the suction hole has a shape extending radially from the rotary shaft of the rotary drum. Therefore, it is not necessary to enlarge (or cure) the rotary drum in order to form the suction holes, thereby making it possible to miniaturize the apparatus.

The rotary drum has a cylindrical shape, and the suction hole extends radially from the rotary shaft. Further, the fixed drum has a cylindrical shape and has a shape in which the switching space portion is opened to the outer peripheral side. Therefore, after the rotating drum and the fixed drum are disassembled, the inside of the suction hole, the switching space, and the like can be easily checked. As a result, it is possible to easily carry out confirmation of remaining foreign matter after cleaning, and to improve convenience.

According to the above-mentioned means 5, when an article is adsorbed to the adsorbing portion, the light from the light emitting means is blocked by the article. On the other hand, when the article is not adsorbed to the adsorbing portion, The light from the light source is not blocked but exits to the outside. Therefore, the light detected by the light receiving means is different depending on the presence or absence of the article, and the adsorption good or bad determination means determines whether the adsorption of the article to the adsorption section is positive or negative based on the detected light. do. Therefore, it is possible to accurately and easily determine whether the article to be adsorbed is adsorbed to the adsorbing section, whether the article not to be adsorbed is mistakenly adsorbed to the adsorbing section, and the like.

It is also conceivable to judge whether the articles are adsorbed or not adsorbed to the adsorbing portions by means of a sensor capable of detecting the articles themselves. In this case, when the intervals (pitches) of the adsorbing portions along the rotating direction of the rotating drum are relatively narrow , There is a possibility that the determination accuracy is lowered. As the distance between the adsorbing portions becomes narrower, the distance between the adsorbed articles becomes narrower, making it difficult to detect the articles by the sensor. On the other hand, according to the means 5 described above, even when the interval (pitch) of the suction portions along the rotating direction of the rotary drum is relatively narrow, the above determination can be performed with high accuracy and ease.

According to the means 6 described above, the adsorption section can be held in a more reliable adsorption state from the time when the adsorption section passes through the adsorption position until the time when the adsorption section reaches the recovery position. Therefore, the article can be returned to the recovery position while being more reliably adsorbed. As a result, it is possible to effectively suppress the drop of the article during transportation, and to more reliably recover the article.

According to the means 6 described above, since the light emitting means is arranged in the negative pressure space portion, foreign matter such as a broken piece of the article is hardly attached to the light emitting means. This makes it possible to more accurately determine whether or not the article to be adsorbed is adsorbed on the adsorption section.

According to the means 7, a negative pressure starts to be supplied to the suction hole of the suction portion, which is to be adsorbed, immediately before the suction position. Therefore, when the adsorption position is reached, the adsorption section can be brought into a state in which the adsorption section can be more surely adsorbed, and it is possible to make it more difficult for the adsorption mistake of the article to occur.

According to the means 8, before the cover film is attached to the container film, the article judged to be good can be picked up and recovered from the sheet preliminarily determined to be defective (defective sheet portion). Therefore, it is possible to effectively reuse the article of good article, and the production cost can be suppressed.

According to the above-mentioned means 8, since the article is adsorbed before reaching the sealing means, the vibration caused by the conveyance is applied to the article to be adsorbed over a long period of time, and the influence of heat or the like caused by the sealing means becomes excessive It is possible to more reliably prevent it. As a result, the article can be recovered in a better state, and the safety and reliability of the recovered article can be secured more reliably. In addition, since the article in such a good state can be recovered, it is possible to omit the re-inspection of the recovered article before reuse, and the production cost can be suppressed more effectively.

In addition, according to the above-mentioned means 8, the article is recovered at a relatively early stage (step) before reaching the seal means. Therefore, when the article has a hygroscopic property (e.g., tablet), moisture absorption in the article can be suppressed.

However, from the viewpoint of improving the safety and reliability in the blister sheet, it is desired to increase the inspection sensitivity by the inspection means. However, if the inspection sensitivity is increased, many cases are judged as bad by mistake. If the case in which it is judged as defective is increased in this way, if a method of discarding the blister sheet of a defective product as it is is employed, many good articles contained in the defective blister sheet become useless, and the cost is extremely increased There is a possibility to do it. In this regard, according to the means 8 described above, since the articles determined as good are collected, even if the inspection sensitivity is increased, there is no occurrence that many articles become useless. Therefore, safety and reliability in the blister sheet can be improved without causing a cost increase (cost increase).

Hereinafter, one embodiment will be described with reference to the drawings.

First, the PTP sheet 1 as a blister sheet will be described. 1 and 2, the PTP sheet 1 includes a container film 3 having a plurality of pocket portions 2, and a container film 3 covering the pocket portion 2, And a cover film 4 attached thereto.

The container film 3 is formed of, for example, a thermoplastic resin material such as PP (polypropylene) or PVC (polyvinyl chloride) or an aluminum foil.

On the other hand, the cover film 4 is made of an opaque material (for example, aluminum foil or the like) coated with a sealant made of, for example, polyester resin or the like.

The PTP sheet 1 is formed in a substantially rectangular shape in plan view (plan view) (rectangular shape), and a pocket column made up of five pocket portions 2 arranged along the sheet long side {long hand direction} And two rows are formed in the {short hand} direction. In other words, a total of ten pocket portions 2 are formed. In each of the pocket portions 2, tablets 5 as articles are accommodated one by one (see FIG. 2).

The PTP sheet 1 is formed into a sheet shape by punching a PTP film 6 (see FIG. 3) as a breister film formed of a strip-shaped container film 3 and a cover film 4.

Next, the outline of a PTP packing machine 11 as a breister packer for manufacturing the PTP sheet 1 will be described with reference to FIG.

On the most upstream side of the PTP packaging machine 11, the fabric of the strip-shaped container film 3 (raw material; original, raw} is rolled and rolled. The leading end side of the container film 3 wound in the form of a roll is guided to the guide roll 13. The container film 3 is caught by the intermittent feed roll 14 on the downstream side of the guide roll 13. The intermittent feed roll 14 is connected to a motor that rotates intermittently, and intermittently feeds the container film 3.

A heating device 15 and a pocket part forming device 16 are disposed in order between the guide roll 13 and the intermittent feed roll 14 along the conveying path of the container film 3. The container film 3 is heated by the heating device 15 so that the container film 3 is heated by the pocket part forming device 16 in a state in which the container film 3 is relatively flexible, A plurality of pocket portions 2 are formed. The forming of the pocket portion 2 is performed at an interval during the conveying operation of the container film 3 by the intermittent conveying roll 14.

The container film 3 sent out from the intermittent conveyance roll 14 is hooked in order of the tension roll 18, the guide roll 19 and the film supporting roll 20. Since the film support roll 20 is connected to the motor rotating constantly, the container film 3 is continuously and at a constant speed. The tension roll 18 is in a state in which the container film 3 is tensioned by the elastic force toward the tension side and the conveying operation between the intermittent feed roll 14 and the film supporting roll 20 (Slack) of the container film 3 due to the upper portion of the container film 3 so that the container film 3 is always kept at a {always} tense state. Thereby, the container film 3 is continuously conveyed between the tension roll 18 and the film supporting roll 20 without stopping.

A tablet filling device 21, a sealing inspection device 22 as an inspection means, and a pick-up device 23 are provided between the guide roll 19 and the film support roll 20 along the conveying path of the container film 3. [ Are arranged in this order.

The tablet filling device 21 has a function as a charging means for automatically charging the tablet 5 to the pocket portion 2. [ The tablet filling device 21 drops the tablet 5 by opening the shutter at predetermined intervals in synchronization with the conveying operation of the container film 3 by the film supporting roll 20, The tablets 5 are filled in the respective pocket portions 2 with accompaniment.

The seal inspection apparatus 22 is provided with a first inspection apparatus T1, a second inspection apparatus D and a third inspection apparatus A in order from the upstream side. The anomaly relating to the tablets 5 and the container film 3 (sheet portion) is inspected by each of these inspection devices T1, D, A. Each of the inspection apparatuses T1, D, and A is capable of specifying the transport amount of the container film 3 by a signal from an encoder (not shown). A more detailed configuration of each of the inspection apparatuses T1, D, and A will be described later.

The pickup device 23 has a function of picking up and recovering a specific tablet 5 from the container film 3 to be transported. The configuration of the pickup device 23 will be described later.

On the other hand, the fabric of the cover film 4 formed in a band shape is wound in a roll shape from the most upstream side.

The leading end of the cover film 4 wound in a roll shape is guided to the heating roll 27 side by the guide roll 26. The heating roll 27 is capable of being pressed against the film supporting roll 20 and is configured so that the container film 3 and the cover film 4 are fed between the rolls 20 and 27 . The cover film 4 is adhered to the container film 3 by the passage of the container film 3 and the cover film 4 between the rolls 20 and 27 in the state of hot pressing, 2 is clogged (closed) with the cover film 4. As a result, the strip 5 of PTP film 6 filled with the tablets 5 in each of the pocket portions 2 is produced. In this embodiment, the film support roll 20 and the heating roll 27 constitute a seal means.

The PTP film 6 fed out from the film supporting roll 20 is hooked in the order of the tension roll 28 and the intermittent feed roll 29 in this order. Since the intermittent feed roll 29 is connected to the intermittently rotating motor, it intermittently feeds the PTP film 6. The tension roll 28 is in a state in which the PTP film 6 is stretched to the side tensed by the elastic force and the tension of the PTP film 6 due to the difference in the conveyance operation between the film support roll 20 and the intermittent feed roll 29 (6) is prevented from slackening so that the PTP film (6) is always kept in a tensioned state.

The PTP film 6 fed out from the intermittent feed roll 29 is hooked in the order of the tension roll 31 and the intermittent feed roll 32 in this order. Since the intermittent feed roll 32 is connected to the intermittently rotating motor, it intermittently feeds the PTP film 6. The tension roll 31 is in a state in which the PTP film 6 is stretched to the side tensed by the elastic force and prevents the PTP film 6 from sagging between the intermittent transport rolls 29 and 32. [

A slit forming device 33 and an engraving device 34 are sequentially disposed between the intermittent conveying roll 29 and the tension roll 31 along the conveying path of the PTP film 6. [ The slit forming device 33 is provided at a predetermined position of the PTP film 6, cut-off " The imprinting device 34 has a function of engraving a mark on a predetermined position (for example, a tag portion) of the PTP film 6. [

The PTP film 6 fed out from the intermittent feed roll 32 is hooked in the order of the tension roll 35 and the continuous feed roll 36 on the downstream side thereof. A sheet punching device 37 is disposed between the intermittent conveying roll 32 and the tension roll 35 along the conveying path of the PTP film 6. [ The sheet punching device 37 is a device for attaching the PTP film 6 to the outer edge of the PTP sheet 1, outer edge ".

The PTP sheet 1 punched out by the sheet punching device 37 is taken out (taken out; take-out} conveyor 38 and temporarily stored in the hopper 39 for finished products. When the PTP sheet 1 is judged to be defective by any one of the inspection apparatuses T1, D and A, the PTP sheet 1 which has been judged as defective is conveyed to the defective sheet discharging mechanism 40 (Separately), and is conveyed to a rejected hopper (not shown).

On the downstream side of the continuous feed roll 36, a cutting (cutting) device 41 is disposed. The unwanted film portion 42 constituting the residual portion (scraped portion) remaining in the form of a strip after the stamping by the sheet striking device 37 is wound around the tension roll 35 and the continuous feed Guided to the roll 36, and then delivered to the cutting device 41. Further, the continuous feed roll 36 is press-contacted with a driven roll, and carries out a transport operation while sandwiching (holding) the unnecessary film portion 42. The cutting device 41 has a function of scraping the unnecessary film portion 42 to a predetermined size. This scrap is stored in the scrap hopper 43 and is then disposed of separately.

The rolls 14, 19, 20, 29, 31, 32 and the like have a positional relationship in which their roll surfaces and the pocket portions 2 face each other. (Recessed portion) in which the recessed portion 2 is accommodated is formed. Therefore, basically, the pocket portion 2 is not squeezed. Further, the conveying operation is performed while the pocket portion 2 is accommodated in the concave portion of each of the rolls 14 and the like, whereby the intermittent conveyance operation and the continuous conveyance operation can reliably be performed.

Next, the inspection apparatuses T1, D, A will be described. As shown in Fig. 5, each of the inspection apparatuses T1, D, and A is provided with an illumination apparatus 70, a camera 71, a process execution apparatus 72, and the like.

The illumination device 70 is capable of irradiating the container film 3 and the tablet 5 (particularly the portion which is finally the PTP sheet 1) from the opening side or the projection side of the pocket portion 2 with light For example, near-infrared light or visible light.

The camera 71 captures (photographs) the container film 3 or the like irradiated with light by the illumination device 70. [ In the present embodiment, as the camera 71, a CCD camera having sensitivity in the wavelength region of the light irradiated from the illumination device 70 is employed. The present invention is not limited to this, and a CMOS camera may be employed. In addition, a color CCD camera is employed in the camera 71 of some inspection apparatuses such as the third inspection apparatus A so that color identification is possible.

Image (image data) (luminance image data or color image data) captured by the camera 71 is converted into a digital signal in the camera 71, and then converted into a digital signal in the form of a digital signal 72).

The processing execution device 72 is configured as a so-called computer system having a CPU as an operating means, a ROM for storing various programs, a RAM for temporarily storing various data such as calculation data and input / output data, And various kinds of processing such as processing can be executed.

The process execution device 72 includes an image memory 73, a test result storage device 74, a judgment memory 75, a data memory 76, a camera timing control device 77, and a CPU and an input / output interface 78), and performs binarization (binarization; binarization} processing or lump {lump; cluster} processing and the like, and defect judgment processing (inspection processing).

The image memory 73 stores image data output from the camera 71. [ The inspection is carried out on the basis of the image data stored in the image memory 73. Of course, the image data may be processed at the time of execution of the inspection. For example, a masking process, a shading correction process, or the like. The shading correction is for correcting the difference in brightness of light caused by the difference in position because there is a technical limitation in uniformly illuminating the entire imaging range of the container film 3 or the like with the light of the illumination device 70.

As shown in Figs. 10 to 13, the rotary drum 51 has a cylindrical shape and is disposed just above the conveying path of the container film 3. Fig. The rotary drum 51 continuously rotates in accordance with the velocity of the container film 3 conveyed by a driving means (not shown). On the outer circumference of the rotary drum 51, a suction portion 51A is provided.

The suction portion 51A has a cylindrical shape extending in a direction projecting from the outer circumferential surface of the rotary drum 51. [ In this embodiment, the suction portion 51A has the same number (the same number) as the number of the pocket portions 2 along the width direction of the container film 3 along the axial direction of the rotary drum 51 (Twelve in this embodiment) are provided at equal intervals along the circumferential direction (circumferential direction) of the rotary drum 51. In this embodiment, The distal end (distal end) side portion of the adsorption section 51A is constituted by a tubular bellows section 51B that can expand and contract along the projecting direction of the adsorption section 51A. The bellows portion 51B is formed of a relatively soft material (for example, a soft rubber or a soft resin).

Each suction portion 51A is provided with a suction hole 51C penetrating from the front end of the bellows portion 51B to the inner circumference of the rotary drum 51. [ Each suction hole 51C extends radially with respect to the rotation axis of the rotary drum 51 (extends in the radial direction of the rotary drum 51). Then, the negative pressure is supplied to the suction hole 51C, whereby the tablet 5 is adsorbed at the tip of the adsorption section 51A. Further, in the adsorbing portion 51A in the state in which the tablet 5 is adsorbed, the bellows portion 51B is in a state of being deformed (contracted) (see FIG. 11).

The adsorption unit 51A sequentially shifts sequentially with respect to the adsorption position P1, the inspection position P2 and the recovery position P3 in accordance with the rotation of the rotary drum 51 (see FIG. 11) .

The adsorption position P1 corresponds to the position below the vertical {vertical} of the axis of the rotary drum 51 and the tablet 5 to be adsorbed is adsorbed to the adsorption section 51A at this position.

The inspection position P2 is a position between the absorption position P1 and the recovery position P3 between the LED 64 and the light reception sensor 65 which will be described later. It is determined whether or not the adsorption unit 51A disposed in this position actually adsorbs the tablet 5 to be adsorbed.

The recovery position P3 is a position displaced by about 270 degrees along the rotation direction of the rotary drum 51 with respect to the suction position P1 and the adsorption of the tablet 5 by the suction portion 51A is canceled at the position . In addition, the tablet recovery box 61 is provided corresponding to the recovery position P3, and the tablets 5 to which the adsorption is released are collected in the tablet recovery box 61. [

An encoder (not shown) is provided in the rotary drum 51, and a signal relating to the rotation angle of the rotary drum 51 is outputted from the encoder to the control device 56 at predetermined time intervals.

The fixed drum 52 has a cylindrical shape and is provided so as not to move in the inner periphery of the rotary drum 51. As shown in Figs. 11 to 16, the fixed drum 52 includes a negative pressure space portion S1, an open space portion S2, and a switching space portion S3, which are openings to the outer circumferential side of the fixed drum, Respectively. The fixed drum 52 has straight through-holes (through-holes) 52A passing through the inner periphery and the space portions S1 to S3. In Fig. 11 and the like, a gap {gap) is formed between both the drums 51 and 52, but in reality, there is almost no gap between the both drums 51 and 52.

The negative pressure space section S1 is a part of the negative pressure space S1 when the adsorption section 51A is disposed in the range including the inspection position P2 from the position slightly before the adsorption position P1 to the position immediately before the recovery position P3 , And communicates with the suction hole 51C of the suction portion 51A. The negative pressure space portion S1 is in a state in which negative pressure is always supplied from the vacuum pump 53 through the through hole 52A and a predetermined air passage (communication pipe) 62 communicating with the through hole 52A Vacuum state) (see Fig. 19). The negative pressure space S1 has a relatively large width along the axial direction of the fixed drum 52. [ Therefore, the negative pressure space portion S1 can communicate with the suction hole 51C arranged in a line along the axial direction of the rotary drum 51 at one time.

The open space S2 is a space communicating with the suction hole 51C of the suction portion 51A when the suction portion 51A is disposed at the recovery position P3. The open space S2 is always open to the atmosphere via the through hole 52A.

When the adsorption section 51A is disposed in the range including the adsorption position P1 from the position immediately before the adsorption position P1 to the position slightly after the adsorption position P1 , And communicates with the suction hole 51C of the suction portion 51A. A plurality of switching space portions S3 are provided at regular intervals along the axial direction of the fixed drum 52 and are arranged in a line along the axial direction of the rotary drum 51 with the rotation of the rotary drum 51 And communicate with one of the suction holes 51C individually. The length of the switching space portion S3 along the circumferential direction of the fixed drum 52 is shorter than the interval between the inner circumferential openings of the suction holes 51C along the rotating direction of the rotary drum 51, So that two or more suction holes 51C are not communicated with the switching space portion S3 at the same time.

Each of the switching spaces S3 is connected to the vacuum pump 53 via a through hole 52A and a predetermined vent pipe 63 communicating with the through hole 52A (see Fig. 19). However, the electromagnetic switching valve 54 is provided in the vent pipe 63. The electronic switching valve 54 switches the state in which the negative pressure is being supplied from the vacuum pump 53 to the switching space portion S3 and the state in which the switching space portion S3 is open to the atmosphere . The state of the switching space portion S3 is switched so that each of the adsorption portions 51A disposed in the adsorption position P1 can be individually switched to the adsorption state or the non-adsorption state. The electromagnetic switching valve 54 is electrically connected to the control device 56 and the operation of the electromagnetic switching valve 54 is controlled by the control device 56. [

An LED 64 as a light emitting means is disposed on the outer periphery of the fixed drum 52 in a state in which it is disposed in the negative pressure space portion S1. The LED 64 is provided in correspondence to the conveying path of the adsorbed tablet 5 from the adsorption position P1 to the recovery position P3. In the present embodiment, the LED 64 is disposed at a position corresponding to the inspection position P2 Respectively. The LEDs 64 are provided in a plurality (five in the present embodiment) along the axial direction of the fixed drum 52 at the same intervals as the intervals of the suction holes 51C along the axial direction of the rotary drum 51 have. When the suction hole 51C is disposed on the front surface of the LED 64, the light from the LED 64 is irradiated to the outside of the rotary drum 51 through the suction hole 51C.

A light receiving sensor 65 as a light receiving means is provided at a position outside the rotary drum 51 and opposed to the LED 64 (see FIG. 11, etc.). The light receiving sensor 65 has a function of detecting light emitted from the LED 64 and is configured to transmit a light receiving signal to the control device 56 when the light is detected.

The lift apparatus 55 is disposed below the conveying path of the container film 3 and is positioned vertically below the rotary shaft of the rotary drum 51. [ The lift device 55 is provided with a driving means which is not shown and is driven by the driving means to move the container film 3 up to a predetermined position (for example, 1 mm to 3 mm) 18) and the lower position separated from the container film 3. In this case, In a state where the lift device 55 is disposed at the above position, the adsorption portion 51A disposed at the adsorption position P1 is brought into contact with the tablet 5 (in this embodiment, both are brought into contact with each other) have. On the other hand, in a state where the lift device 55 is disposed at the lower position, the adsorption portion 51A disposed at the adsorption position P1 is separated from the tablet 5.

The lift device 55 is electrically connected to the control device 56. The lifting and lowering operation of the lift device 55 is controlled by the control device 56. [

17, the lift apparatus 55 is provided with a pair of rotating rollers 55A and 55B extending in the width direction of the container film 3. As shown in Fig. The rotating rollers 55A and 55B are freely rotatable driven rollers. When the container film 3 is lifted by the lifting device 55, the outer peripheral surface thereof comes into contact with the container film 3. Then, the rotating rollers 55A and 55B rotate with contact with the container film 3 to be conveyed.

Annular grooves 55C extending in the circumferential direction of the rotary rollers 55A and 55B are formed on the outer periphery of both the rotary rollers 55A and 55B by rotation rollers 55A and 55B, The number of the pocket portions 2 along the width direction of the container film 3 is set to be the same as the number of the pocket portions 2 along the axial direction of the container film 3. The intervals of the groove portions 55C along the axial direction of the rotating rollers 55A and 55B are substantially equal to the intervals of the pocket portions 2 along the width direction of the container film 3. [ The width of the groove 55C is larger than the outer diameter of the pocket 2 and the depth of the groove 55C is larger than the height of the pocket 2. [ Therefore, when the lift device 55 is disposed at the upper position and the container film 3 is lifted, the pocket portion 2 is disposed in the groove portion 55C, Distortion, and the like are suppressed.

In this embodiment, the pocket portion 2 is arranged in the groove portion 55C even when the rotary rollers 55A and 55B are disposed at the lower positions. Therefore, the moving distance of the lift device 55 from the lower position to the upper position can be relatively reduced. As a result, the lifting of the container film 3 can be performed quickly, and the adsorption of the tablet 5 can be performed more reliably.

The control device 56 is constituted by a so-called computer system in the same manner as the processing execution device 72 described above. The control device 56 is electrically connected to the inspection devices T1, D, and A, respectively, and is configured to be able to receive information on the inspection results stored in these devices. 20, the control unit 56 sets the number of tablets J1 (for example, J1) for each sheet predicting unit 7, based on the information about the test results received from the testing devices T1, X1 to X9, Y1, Z1, and Z2 with respect to each tablet 5 and the sheet portion indicated by J10 to J10.

In the present embodiment, some of the inspection items executed in the inspection apparatuses T1, D, and A are duplicated. However, the control apparatus 56 may be configured such that, (T1, D, A), it is determined that the inspection item is defective. For example, in the inspection item X1, a certain tablet 5 is determined to be good in the inspection apparatuses T1 and D, and when it is determined in the inspection apparatus A that it is defective (defective), the control apparatus 56) specifies that some of the tablets (5) are defective in the inspection item X1.

The control device 56 controls the electronic switching valve 54 and the lift device 55 on the basis of the result of determination of the seat portion 7 (see Fig. 20) The electronic switching valve 54 and the lift device 55 are controlled so that only the tablets 5 of good goods are adsorbed from the adsorbing section 51A.

Specifically, the control device 56 first determines whether or not the electronic switching valve 54 is to be switched and the lift device 55 is to be elevated or lowered based on the judgment result of the seat determining part 7 (Scheduled operation setting process). The operation schedule related to the set electronic switching valve 54 and the lift apparatus 55 is stored in addition to the operation schedule table KT (see Fig. 21) of the RAM in the control device 56. [

21 shows that the electronic switching valve 54 is operated so that the negative pressure is supplied to the switching space portion S3 and the electronic switching valve 54 is switched so that the switching space portion S3 is opened to the atmosphere. Quot; N ". In other words, the time when the tablet 5 is adsorbed is denoted by "Y", and the case where the tablets 5 are not adsorbed is denoted by "N". The operation of the lift device 55 to be disposed at the upper position is denoted by "Y", and the operation of the lift device 55 to be disposed at the lower position is denoted by "N". In Fig. 21, refinement numbers J1 to J10 of the tablet 5 corresponding to the electromagnetic switching valve 54 to be operated are also shown together for ease of explanation.

In addition, the control device 56 may be operable at predetermined timing (for example, every timing immediately after the suction hole 51C of the suction portion 51A is turned to the non-discharge state with respect to the switching space portion S3) The switching of the electronic switching valve 54 corresponding to the suction portion 51A arranged in a line in the axial direction of the rotary drum 51 and the shifting of the lift device 55 To the predetermined execution tables JT1 and JT2 (see Fig. 21).

The control device 56 then determines whether or not the suction hole 51C of each suction portion 51A corresponding to the data of the execution table JT1 reaches the switching table S3 at the timing immediately before the suction hole 51C reaches the switching space portion S3 JT1, the operation of the electromagnetic switching valve 54 and the lift device 55 is controlled. The execution timing of the operation control of the electromagnetic switching valve 54 and the lift device 55 is determined based on the signal from the encoder of the rotary drum 51. [

The control device 56 determines whether or not the data of the execution table JT2 and the data of the light receiving sensor 51A at the timing when each of the suction portions 51A corresponding to the data of the execution table JT2 reaches the inspection position P2 Whether or not the tablets 5 to be adsorbed are actually adsorbed to the adsorbing portion 51A and whether or not the tablets 5 to be adsorbed are adsorbed on the adsorbing portion 51A Whether or not it is mistakenly adsorbed by the user. When the adsorption abnormality such as not adsorbing the tablet 5 to be adsorbed to the adsorption section 51A is generated, the control device 56 executes the adsorption abnormality processing. Examples of the adsorption abnormality treatment include a process of urgently stopping the operation of the PTP packing machine 11, a process of notifying that the adsorption abnormality has occurred, and the like.

Next, the control process (adsorption determination process) related to the switching of the electronic switching valve 54, the setting process of the lift device 55 to be raised and lowered (operation scheduled setting process), and the adsorption determination of the tablet 5, Will be described.

First, referring to Fig. 22, the scheduled operation setting process will be described. In the scheduled operation setting process, first, in step S11, it is determined whether or not the inspection results (inspection results for one sheet) of one sheet predicting section 7 are inputted from the respective inspection devices T1, D, A. Then, the process of step S11 is repeated until the inspection result for one sheet is input, and when the inspection result for one sheet is inputted (step S11: YES), the process proceeds to step S12.

Subsequently, in step S12, based on the inspection results input from the inspection apparatuses T1, D, and A, the tablets 5 and the inspection items X1 to X9, Y1, Z1 and Z2 (see Fig. 20).

Subsequently, in step S13, both sides of the sheet presupposition 7 are judged on the basis of both the specified tablets 5 and the portions for the inspection items X1 to X9, Y1, Z1 and Z2 for the sheet portion . In the present embodiment, when there is no failure judgment in all of the inspection items X1 to X9, Y1, Z1 and Z2 in each tablet 5 and the sheet portion (step S13: YES) And in step S14, the normal operation setting process is performed, and the process returns to step S11.

In the normal operation setting process, the operation schedule of the electromagnetic switching valve 54 and the lift device 55 is set such that the tablet 5 is not withdrawn from the good product sheet portion and the lift device 55 is disposed at the lower position Respectively.

Specifically, in the adsorption position P1, the electronic switching valve 54 is scheduled to be switched so that the suction holes 51C of the suction portions 51A corresponding to the good sheet portions are open to the atmosphere . For example, in the case where the seat portion 7 indicated by the serial number LA1 is a good sheet portion, in each of the suction portions 51A corresponding to the tablet 5 supplied to the good sheet portion, the suction hole 51C The switching schedule of the corresponding electromagnetic switching valve 54 is set so as to be open to the atmosphere. Further, the lifting / lowering schedule of the lifting device 55 is set so that the lifting device 55 is disposed at a lower position. Then, the operation schedule of the set electronic switching valve 54 and the lift apparatus 55 is added to the operation schedule table KT and stored.

On the other hand, if the determination is negative in step S13, it is determined in step S15 whether the inspection item determined to be defective is inspection item Z1 or inspection item Z2. Here, if it is judged that the inspection item Z1 or the inspection item Z2 is defective (step S15: YES), the process proceeds to step S14, and the normal operation setting process is performed. In other words, in the present embodiment, when it is judged that the inspection item of the "sheet-like hair" or the "sheet-like foreign matter" is defective, all the tablets 5 in the defective sheet portion are judged to be satisfactory from the inspection items X1 to X9 Is set so as not to perform the recovery of tablets (5) from the sheet preliminary part (7). This takes into account the possibility that hair or foreign matter may be in contact with any of tablets (5).

On the other hand, when it is not judged that both of the inspection items Z1 and Z2 are defective (step S15: NO), the process advances to step S16 to specify the sheet pretreating part 7 related to the failure determination as a defective sheet part. For example, if at least one of the tablets 5 in the sheet pretreating section 7 indicated by the serial number LA2 is judged to be defective, the sheet pretreating section 7 is specified as a defective sheet section.

In the succeeding step S17, the recovery operation setting process is performed based on the information on the specified both sides, and the process returns to step S11. In the recovery operation setting processing, a negative pressure is supplied to the suction port 51C of each suction portion 51A corresponding to the defective sheet portion, corresponding to the tablets 5 judged as good, in the suction position P1, The switching schedule of the electronic switching valve 54 is set so that the state corresponding to the tablet 5 determined to be defective is in the state of being open to the atmosphere.

Further, on the basis of the predetermined switching schedule, the lift apparatus 55 is set to ascend and descend. Specifically, when the switching schedule of the electromagnetic switching valve 54 is set such that all of the suction holes 51C of the suction portion 51A aligned in the axial direction of the rotary drum 51 are open to the atmosphere , The lifting / lowering schedule of the lift apparatus 55 is set so as to be disposed at the lower position. On the other hand, when the electronic switching valve 54 is scheduled to be switched so that the negative pressure is supplied to at least one of the suction holes 51C of the suction unit 51A aligned in the line, And sets the ascending / Then, the operation schedule of the set electronic switching valve 54 and the lift apparatus 55 is added to the operation schedule table KT and stored.

Next, the adsorption determination processing will be described with reference to FIG. In this embodiment, the determination process for one of the adsorption units 51A disposed in the inspection position P2 will be described. In actuality, however, all of the adsorption units 51A disposed in the inspection position P2 The similar determination processing is performed.

In the adsorption determination processing, first, in step S21, it is determined repeatedly whether or not the adsorption unit 51A has reached the inspection position P2, that is, whether it is a determination timing. In addition, the determination timing is determined based on the signal from the encoder of the rotary drum 51.

If the determination timing is reached (step S21: YES), it is determined in step S22 whether or not a light receiving signal is input from the light receiving sensor 65. [ If a light reception signal is input (step S22: YES), the process proceeds to step S23. If the light reception signal is not input (step S22: NO), the process proceeds to step S24.

In step S23, it is determined whether or not the switching schedule of the electronic switching valve 54 is set so that the suction hole 51C is opened to the atmosphere, taking into consideration the data of the execution table JT2. If the switching schedule of the electronic switching valve 54 is set so that the suction hole 51C is opened to the atmosphere (step S23: YES), the process proceeds to step S25. If it is determined in step S25 that the tablets 5 that are not to be adsorbed are not adsorbed by mistake, the adsorption is determined to be normal, and the process returns to step S21.

On the other hand, when the scheduled changeover of the electromagnetic switching valve 54 is set so as to supply the negative pressure to the suction hole 51C (step S23: NO), the process proceeds to step S26. In step S26, if the tablets 5 to be adsorbed are not adsorbed, the adsorption abnormality processing is executed, and the process returns to step S21.

In step S24, it is determined whether or not the switching schedule of the electronic switching valve 54 is set so that the suction hole 51C is opened to the atmosphere, taking into account the data of the execution table JT2. Here, in the case where the switching schedule of the electronic switching valve 54 is set so that the suction hole 51C is opened to the atmosphere (step S24: YES), the process proceeds to step S26. Then, in step S26, since the tablets 5 that are not to be adsorbed are mistakenly adsorbed, the adsorption abnormality processing is executed, and the process returns to step S21.

On the other hand, when the scheduled changeover of the electromagnetic switching valve 54 is set so as to supply the negative pressure to the suction hole 51C (step S24: NO), the process proceeds to step S25. If it is determined in step S25 that the tablet 5 to be adsorbed is normally adsorbed, it is determined that adsorption is normal, and the process returns to step S21.

As described in detail above, according to the present embodiment, when the tablet 5 is adsorbed, the container film 3 is lifted by the lifting device 55, and the tablet 5 is moved to the adsorption part 51A. Therefore, the tablet 5 can be more reliably adsorbed by the adsorption portion 51A, and the tablet 5 can be more reliably recovered.

Since the container film 3 is lifted by the rotary rollers 55A and 55B which can be rotated in accordance with the conveyance of the container film 3, it is ensured that the container film 3 is not scratched when lifted And the quality of the PTP sheet 1 can be improved.

Further, when the tablets 5 approach the adsorbing portion 51A, the rotating drum 51, the fixed drum 52, etc., which are heavy and have a complicated structure, are not moved up and down. Therefore, it is not necessary to provide a large-scale mechanism, and it is possible to reduce costs related to the manufacture of the apparatus, and realize more stable and higher-speed operation.

In addition, when the tablet 5 is not adsorbed, the tablet 5 is separated from the adsorbing portion 51A. Therefore, consumption (wear and deterioration) of the adsorption section 51A can be effectively suppressed, and the adsorption section 51A can be maintained in a proper state for a longer period of time. In addition, since the adsorption section 51A is separated from the tablet 5, damage or contamination of the tablet 5 caused by the contact of the adsorption section 51A can be more reliably prevented.

In the present embodiment, at least the portion of the adsorption portion 51A that contacts the tablet 5 (bellows portion 51B) is formed of a relatively soft material. Therefore, the load given to the tablet 5 at the time of adsorption can be reduced, and the tablet 5 can be recovered in a better state. If the portion of the adsorption section 51A which is in contact with at least the tablet 5 is formed of a relatively soft material, it is apprehended that consumption of the adsorption section 51A tends to progress. However, as described above, ) Can be effectively suppressed, so that such concern can be eliminated.

In addition, when the tablet 5 is adsorbed, the load applied to the tablet 5 can be further reduced by reducing the bellows portion 51B. As a result, the tablets 5 can be recovered in a better state. As the bellows portion 51B is shrunk, the tablet 5 is lifted from the pocket portion 2 and the tablets 5 are discharged from the pocket portion 2 in this state. Therefore, it is possible to more reliably prevent the tablet 5 from coming into contact with the pocket portion 2, and it is possible to effectively suppress damage to the suction mist and the tablet 5.

In addition, the suction hole 51C has a shape extending radially from the rotary shaft of the rotary drum 51. [ Therefore, it is not necessary to enlarge the rotary drum 51 to form the suction holes 51C (large-hardening), so that the size of the apparatus can be reduced.

After the rotating drum 51 and the fixed drum 52 are disassembled, the inside of the suction hole 51C and the switching space portion S3 can be easily checked. As a result, it is possible to easily carry out confirmation of remaining foreign matter after cleaning, and to improve convenience.

The tablets 5 to be adsorbed are subjected to adsorption determination processing using an LED 64 that emits light that can pass through the suction hole 51C and a light receiving sensor 65 that can receive light from the LED 64, Whether or not the tablets 5 that are not to be adsorbed by the adsorbing section 51A are adsorbed to the adsorbing section 51A and whether or not the tablets 5 that are not adsorbed by the adsorbing section 51A are adsorbed by the adsorbing section 51A can be accurately and easily performed. According to the present embodiment, even when the intervals (pitches) of the suction portions 51A along the rotating direction of the rotary drum 51 are relatively narrow, the above determination can be performed with high accuracy and ease.

In the present embodiment, since the LED 64 is disposed in the negative pressure space S1, foreign matter such as a broken piece of the tablet 5 hardly adheres to the LED 64. [ This makes it possible to carry out the determination as to whether or not the tablets 5 to be adsorbed are adsorbed on the adsorption section 51A with higher precision.

In addition, since the suction hole 51C of the suction portion 51A communicates with the negative pressure space portion S1 during the period from passing the suction position P1 until reaching the recovery position P3, The adsorption section 51A can be held in a more reliable adsorption state. Therefore, the tablet 5 can be conveyed in the recovery position P3 with more reliably adsorbed. As a result, the dropping of the tablet 5 at the time of transportation can be effectively suppressed, and the tablet 5 can be more reliably recovered.

In the present embodiment, just before the adsorption position P1, the suction hole 51C of the adsorption section 51A, which is intended to adsorb the tablet 5, communicates with the switching space section S3. Therefore, the supply of the negative pressure to the suction hole 51C can be started just before the suction position P1, and the suction portion 51A can be brought into the suctionable state more reliably when the suction position P1 is reached have. As a result, the adsorption failure of the tablet 5 can be more difficult to occur.

Before the cover film 4 is attached to the container film 3, the tablets 5 judged to be good are adsorbed from the sheet preliminarily determined to be defective (defective sheet portion) 7 and recovered There is a number. Therefore, the tablets 5 of good products can be effectively reused, and the production cost can be suppressed.

Since the tablet 5 is adsorbed before reaching the film transfer roll 20 and the heating roll 27 (seal means), the vibration accompanying the conveyance is applied to the tablets 5 to be adsorbed for a long period of time It is possible to more reliably prevent the influence of the discarding, the heat accompanying the seal, and the like. As a result, the tablets 5 can be recovered in a better state, and the safety and reliability of the recovered tablets 5 can be secured more reliably. In addition, since the tablets (5) in such a good condition can be recovered, it is possible to omit the retesting of the recovered tablets (5) before reuse and to suppress the production cost more effectively.

In addition, since the tablet 5 is recovered at a relatively early stage before reaching the film transfer roll 20 and the heating roll 27 (seal means), moisture absorption in the tablet 5 can be suppressed.

Since the tablet 5 judged to be good from the defective sheet portion is recovered, even if the inspection sensitivity by the sealing inspection device 22 is increased in order to further improve the safety and reliability in the PTP sheet 1, A situation in which many tablets 5 become useless does not occur. Therefore, safety and reliability in the PTP sheet 1 can be further improved without causing a cost increase (cost increase).

In the present embodiment, as the PTP sheet 1 of a defective product, as shown in Fig. 24, when the foreign matter P is detected, all the tablets 5 are recovered, and all of the pocket portions 2 As shown in Fig. 25, it is possible that the tablet 5 remains. Here, the PTP sheet 1 of which all the pocket portions 2 are empty defective items is determined as being abnormal when the sheet pretreating portion 7 is abnormal in the sheet itself or the tablets 5 are not contained in some pocket portions 2 So-called " refill lost "). The defective PTP sheet 1 having the tablets 5 remaining is discharged as a result of the sheet preliminarily determined to be defective due to the abnormality of the remaining tablets 5. Therefore, by looking at the state of the discharged PTP sheet 1, it can be easily judged by what cause it is judged to be defective. When the tablets 5 remain, it is possible to easily identify the occurrence of the abnormalities by viewing the remaining tablets 5 and the sheet portion. As a result, it is possible to easily specify an inspection item in which a defect has occurred, and appropriate measures can be taken early.

Further, the present invention is not limited to the description of the above embodiment, and the following description is also applicable. Needless to say, other applications and modifications that are not illustrated in the following are also possible.

In this case, since the driving means for moving the lift apparatus 81 up and down becomes unnecessary, the apparatus can be made smaller and simpler, and at the same time, the apparatus can be operated at a higher speed. In this case, since the eccentric rollers 81A and 81B are rotated in accordance with the conveying speed of the container film 3, it is possible to more reliably prevent the container film 3 from being scratched, The quality of the sheet 1 can be improved.

(b) In the above embodiment, the suction hole 51C of the suction portion 51A is configured to be open to the atmosphere at the recovery position P3, but a positive pressure {positive pressure} is applied to the suction hole 51C .

For example, the pickup device 23 can be used even when a predetermined pocket portion is to be left empty.

(e) In the above embodiment, the adsorption and non-adsorption of the tablets 5 in the sheet pretreating section 7 are determined based only on the opposite sides of the sheet permitting section 7. On the other hand, the adsorption and non-adsorption of the tablets 5 in the sheet pretreating section 7 can be carried out in such a manner that both of the sheet pretreating section 7 itself and front and rear ) And the upstream portion (downstream portion) of the sheet (7). For example, when it is determined that the sheet preliminarily positioned at the front and rear of a certain sheet preliminary portion 7 is defective in a predetermined inspection item (for example, the inspection items Z1 and Z2) The adsorption of the tablets 5 may be stopped in any one of the sheet preparing portions 7 irrespective of the portion of the tablet 7 to which the tablets 5 are adhered. In this case, when the tablets 5 are adsorbed, it is possible to more reliably prevent the foreign matter or the like of the adjoining sheet judging portion 7 judged as poor from being adsorbed by the adsorbing portions 51A. This makes it possible to further enhance safety and the like in the recovered tablet 5.
