Description

  The present invention relates to a packaging machine for blister packaging sheets (hereinafter referred to as “PTP sheets”) for packaging tablets.

  Generally, a PTP sheet has, for example, a container film having a plurality of pocket portions and a cover film attached to the container film so as to close the pocket portions. The pocket part is filled with articles such as tablets and capsules. In addition, the PTP sheet is formed by punching a long PTP film in which the article is filled in the pocket portion.

  Further, such a PTP sheet is formed by a dedicated PTP wrapping machine with respect to a container film fed from the most upstream side of the wrapping machine, forming a pocket portion, filling the article, attaching a cover film, The film is manufactured by sequentially performing various processes such as punching of the film.

  By the way, in the manufacturing process of the PTP sheet, it is necessary to prevent the dust from adhering to the inside of the pocket portion or the article. Therefore, a method has been proposed in which the PTP packaging machine is covered with a predetermined cover, and clean air is fed into the cover so that filling of the article, attachment of the cover film, etc. is performed in a clean space. (See, for example, Patent Document 1).

Registered Utility Model No. 3010097

  However, in the above method, the PTP sheet is transported from the PTP packaging machine to a weight checker, an inspection conveyor, or the like located outside the cover along a substantially horizontal path. Therefore, the PTP sheet carried out of the cover is covered with the wind blown from the PTP sheet carry-out port of the cover, and there is a possibility that the PTP sheet cannot be conveyed in a stable state. In contrast, in order to stably transport the PTP sheet, the air volume from the carry-out port is reduced by increasing the opening area of the carry-out port or reducing the amount of air blown into the cover. Can be considered. However, in this case, the cleanliness in the space in the cover may be impaired.

  Further, the PTP sheet is usually carried out from the first space (clean zone) inside the cover to the second space (general zone) outside the cover by a carrying-out means that can reciprocate such as a conveyor or a claw attached to the conveyor. However, in the above method, the carry-out means is provided across the clean zone and the general zone. Therefore, when the carry-out means returns from the general zone to the clean zone, there is a possibility that dust adhering to the carry-out means is brought into the clean zone.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to stably transport a PTP sheet unloaded from a first space provided with a filling means and the like in the first space. It is in providing the PTP packaging machine which can prevent the penetration | invasion of the dust with respect to more reliably.

The conveyor 31A is configured to continuously move along an annular moving path. The conveyor claw 31B moves with the movement of the conveyor 31A, and pushes and conveys the PTP sheet 1 by the movement of the conveyor 31. The conveyance table 31C extends from immediately before the end of the suction rail 30 to the sheet storage device 32, and is constituted by a pair of rails extending along the moving direction of the conveyor 31B. The PTP sheet 1 is initially conveyed by the conveyor pawl 31B while being adsorbed to the adsorption rail 30, and then placed on the conveyance table 31C as shown in FIGS. 3 and 4. 32.

  As shown in FIG. 5, the sheet storage device 32 includes a plurality of pillar portions 32A, a support portion 32B, a lower limit position sensor 32C, and an upper limit position sensor 32D.

  The column portion 32A extends in the vertical direction and is provided in a plurality. Further, each of the pillar portions 32A has an L shape in a cross section along the horizontal direction, and is disposed at a position corresponding to a rectangular corner when viewed in plan. And the rectangular parallelepiped accommodation space 32S which can be accommodated in the state which piled up the several PTP sheet | seat 1 horizontally defined by the pillar part 32A is formed in the downward position rather than the support part 32B. In addition, an upper opening 32P1 that opens upward is provided above the accommodation space 32S. The upper opening 32P1 has a shape capable of passing through the horizontal PTP sheet 1, and the PTP sheet 1 conveyed by the conveyor pawl 31B is put into the upper opening 32P1 (see FIG. 4). .

  The support part 32B is provided in the upper part of the accommodation space 32S in the vicinity of the upper opening 32P1, and as shown in FIG. 6, the PTP sheet 1 put into the upper opening 32P1 by the support 32B. Is configured to be temporarily supported. The support part 32B includes a first support part 32B1 and a second support part 32B2.

  The first support portion 32B1 is provided so as not to move with respect to the column portion 32A. On the other hand, the second support portion 32B2 is movable in the contact / separation direction with respect to the first support portion 32B1 by an operating means (not shown). Then, in a state where the PTP sheet 1 is supported by both the support portions 32B1 and 32B2, as shown in FIG. 7, the second support portion 32B2 is separated from the first support portion 32B1, so that the PTP sheet by the second support portion 32B1. 1 support is released. Thereby, the PTP sheet 1 falls in the accommodation space 32S in a state where the pocket portion 5 faces downward. When the PTP sheet 1 is dropped, the short side part supported by the second support part 32B2 is shorter than the short side part supported by the first support part 32B1 among the short side parts on the outer periphery of the PTP sheet 1. Slightly falls first.

  The sheet storage device 32 includes lower support means (not shown), and the PTP sheet 1 dropped from the support portion 32B is supported by the lower support means. That is, the PTP sheet 1 that falls in the accommodation space 32S is accommodated in a state of being stacked in the accommodation space 32S by the lower support means.

  The lower limit position sensor 32C is constituted by, for example, a photoelectric sensor, and detects whether or not the PTP sheet 1 exists at a predetermined lower limit position set in advance in the accommodation space 32S. When the PTP sheet 1 is present at the lower limit position, that is, when the PTP sheet 1 is stacked more than a preset lower limit amount, the lower limit position sensor 32C controls the PTP sheet stacking device 29. A normal signal indicating that the loaded amount is normal is transmitted to the means (not shown). On the other hand, when the PTP sheet 1 is not present at the lower limit position, that is, when the stacked amount of the PTP sheets 1 is less than the lower limit amount, the lower limit position sensor 32C has an abnormal stacking amount regarding the lower limit position. Is transmitted to the control means.

  The upper limit position sensor 32D is configured by, for example, a photoelectric sensor, and detects whether or not the PTP sheet 1 is present at a predetermined upper limit position set in advance in the accommodation space 32S. When the PTP sheet 1 is not present at the upper limit position, that is, when the PTP sheet 1 is stacked less than the preset upper limit amount, the upper limit position sensor 32D has a normal stacking amount to the control means. A normal signal indicating that is transmitted. On the other hand, when the PTP sheet 1 is present at the upper limit position, that is, when the stacked amount of the PTP sheet 1 is equal to or greater than the upper limit amount, the upper limit position sensor 32D has an abnormal stacking amount regarding the vertical position. Is transmitted to the control means.

  When a normal signal is transmitted to both the lower limit position sensor 32C and the upper limit position sensor 32D to the control means, the control means causes the PTP sheet stacking device 29 to normally operate. That is, the PTP sheet 1 is allowed to fall with respect to the accommodation space 32S. On the other hand, when the stacked amount of the PTP sheet 1 is less than the lower limit value and an abnormal signal is transmitted to the control means by the lower limit position sensor 32C, or the stacked amount of the PTP sheet 1 is equal to or more than the upper limit amount. Yes, when an abnormal signal is transmitted to the control means by the upper limit position sensor 32D, the control means stops the fall of the PTP sheet 1 with respect to the accommodation space 32S, for example, by stopping the conveyor 31A.

  Further, the sheet storage device 32 includes a discharge unit (not shown), and the discharge unit temporarily releases the support of the PTP sheet 1 by the lower support unit according to an instruction from the boxing device 42 described later. Then, every time the release is performed, the second PTP sheet 1 accommodated in the accommodation space 32S passes through the lower opening 32P2 that opens downward from the accommodation space 32S in order from the lowermost one, and the second It is dropped to the device 40 side.

  As shown in FIG. 2, the second device 40 includes a conveyor 41 as a second transport unit and a boxing device 42.

  The conveyor 41 is arrange | positioned under the said lower side opening part 32P2 (refer FIG. 5), and is comprised so that it may move continuously along a cyclic | annular movement path | route. Then, the PTP sheet 1 dropped on the conveyor 41 from the accommodation space 32 </ b> S is arranged on the conveyor 41 and conveyed to the boxing device 42 by the conveyor 41.

  The boxing device 42 is disposed downstream of the conveyor 41 and has a function of boxing the PTP sheet 1 conveyed by the conveyor 41.

  Next, features of the present invention will be described.

  In the present embodiment, the first device 20 is configured by being covered with a cover (not shown), and the internal space is the first space 20S. The first space 20S is in a state of being blocked from the outside air except for an outside air intake port 34 described later and a hole 51H described later. Furthermore, at least a pocket portion forming device 22, a filling device 23, a sealing device 25, and a sheet punching device 28 are disposed in the first space 20S.

  Further, the first device 20 is provided with an outside air intake port 34 communicating with the first space 20S. The outside air intake port 34 passes through a filter 35 for removing dust and the filter 35. The fan 36 for taking in the clean outside air into the first space 20S is provided. The inside of the first space 20S is a positive pressure higher than the atmospheric pressure by the outside air taken in by the fan 36, and is a clean zone in which dust from the outside is difficult to enter.

  Furthermore, the 2nd apparatus 40 which has the said conveyor 41 and the boxing apparatus 42 is arrange | positioned in the 2nd space 40S (general zone) located outside the said 1st space 20S. The second space 40S has a lower pressure (in the present embodiment, atmospheric pressure) than the pressure in the first space 20S.

  In addition, in this embodiment, a plate-like partition 51 for separating the two spaces 20S and 40S is provided between the first transport device 31 and the conveyor 41. As shown in FIGS. 5 and 7, the partition 51 is formed with a hole 51 </ b> H having a rectangular cross section penetrating in the thickness direction of the partition 51. The hole 51H has a shape that allows at least the horizontal PTP sheet 1 to pass through, and is one size larger than the outer peripheral shape of the PTP sheet 1 in this embodiment. The above-described sheet storage device 32 is inserted through the hole 51H. In other words, the sheet storage device 32 is fitted in the hole 51A and is provided across the first space 20S and the second space 40S. Therefore, in the present embodiment, the PTP sheet 1 passes through the hole 51H from the first space 20S to the second space 40S and is lowered (dropped) in the accommodation space 32S, so that the PTP sheet 1 is removed from the first space 20S. It is carried out to the two spaces 40S (that is, from the first device 20 to the second device 40).

  Further, as shown in FIGS. 2 to 4 and FIGS. 6 and 7, the PTP sheet 1 is configured such that the pocket portion 5 always faces downward from the time when the sheet is stored in the sheet storage device 32 to the time when it is conveyed by the conveyor 41. ing.

  As described above in detail, according to the present embodiment, the PTP sheet 1 is dropped through the hole 51H, thereby causing the PTP from the first space 20S (clean zone) to the second space 40S (general zone). The sheet 1 is carried out. That is, the PTP sheet 1 is carried out in one way from the first space 20S to the second space 40S. Therefore, dust is not brought into the first space 20S from the second space 40S by the carry-out means, and dust can be prevented from entering the first space 20S (clean zone) more reliably.

  Furthermore, in the present embodiment, the first space 20S has a positive pressure, and the second space 40S has a lower pressure than the atmospheric pressure of the first space 20S. Therefore, the wind blown from the hole 51H to the second space 40S blows downward, and the PTP sheet 1 on the conveyor 41 is pressed against the conveyor 41 by the wind. Therefore, it is possible to effectively suppress the PTP sheet 1 from being blown by the wind, and the PTP sheet 1 can be conveyed in a stable state. That is, it is possible to stably transport the PTP sheet 1 by using the wind that has conventionally caused unstable transport of the PTP sheet.

  Furthermore, the ventilation area in the hole 51H can be reduced by the PTP sheet 1 descending the accommodation space 32S. Thereby, the air volume which blows off from the hole 51H to the 2nd space 40S can be made smaller, and the PTP sheet 1 can be conveyed in the more stable state.

  In particular, in this embodiment, since the PTP sheet 1 is stacked in the accommodation space 32S provided in the hole 51H, the ventilation area in the hole 51H can be reduced more effectively. As a result, the PTP sheet 1 can be conveyed in a more stable state.

  In addition, the PTP sheet 1 is configured such that the pocket portion 5 always faces downward from the time of accommodation in the accommodation space 32S to the time of conveyance by the conveyor 41. Therefore, the upper surface of the PTP sheet 1 is a flat surface, and is in a state where it is susceptible to wind. As a result, even if there is a PTP sheet 1 that has not fallen in the accommodation space 32S, such as being caught by the sheet accommodation device 32, the PTP sheet 1 is forcibly lowered to the accommodation space 32S by the wind. Can do. As a result, the PTP sheets 1 can be more reliably stacked in a normal state.

  Furthermore, since the upper surface of the PTP sheet 1 is a flat surface, the PTP sheet 1 on the conveyor 41 can be more reliably pressed against the conveyor 41 by the wind. Therefore, the PTP sheet 1 can be conveyed in a more stable state.

  Further, according to the present embodiment, when the PTP sheet 1 is dropped into the accommodation space 32S, one short side portion of the PTP sheet 1 is configured to fall slightly earlier than the other short side portion. ing. Thereby, the PTP sheet 1 can be dropped with the central axis (long axis) extending parallel to the extending direction of the long side portion thereof being inclined and supported by the lower support means. That is, the PTP sheet 1 can be dropped in a very stable posture in which rotation about the long axis is difficult to occur. As a result, it is possible to effectively suppress the rotation of the PTP sheet 1 with the long axis that is particularly likely to be generated as the rotation axis, and the PTP sheets 1 can be more reliably stacked in a normal state.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.
