The second supply hopper 40 is a device for dropping the lowermost blister package 1B onto the transport table 14 one by one from a package stack 2B in which a plurality of blister packages 1B are stacked.

The second supply hopper 40 includes a pair of guides 41 provided on the carriage 13, an upper shutter 42 that opens and closes a lower end opening of a cavity 41 a between the guides 41, and a guide below the upper shutter 42. A plurality of lower shutters 43 that open and close the lower end openings of the cavities 41a between 41, and an interlocking drive mechanism 44 that interlocks and opens the upper shutter 42 and the lower shutter 43.
Since the second supply hopper 40 has the same configuration and function as the first supply hopper 30, detailed description of the second supply hopper 40 is omitted. The horizontal position of the guide 41 of the second supply hopper 40 is aligned with the horizontal position of the guide 31 of the first supply hopper 30 (see FIG. 5).

  The second blister package 1B accommodated in the cavity 41a between the pair of guides 41 lies with its long side direction being the front-rear direction, the first flange portion 8 is directed forward, The flange portion 9 is directed rearward. Further, the back surface of the second blister package 1B (surface on the side where the convex storage portion 6 is recessed) is directed upward, and the front (front) surface (convex storage portion) of the second blister package 1B. The surface from which 6 protrudes is directed downward, and in this state, the second blister package 1B is laminated.

  The interlocking drive mechanism 44 and the transport motor 22 of the pusher 20 are synchronously controlled by the control unit 70. Specifically, the lower shutter 43 is moved by the interlocking drive mechanism 44 between the time when the pushing finger 24 passes forward below the guide 31 and the time when the subsequent pushing finger 24 reaches below the guide 31. Since it is opened twice, the second blister package 1B that has fallen is pushed by the subsequent pushing finger 24.

3. Operation of the Stacking Device The endless chain 23 circulates continuously by driving the transport motor 22 of the pushing device 20 by the control unit 70. As a result, the pushing finger 24 protruding upward from between the pair of transport tables 15 moves forward. Therefore, the pushing finger 24 sequentially passes forward under the guide 31 of the first supply hopper 30. Similarly, the pushing finger 24 sequentially passes forward under the guide 41 of the second supply hopper 40.

  Further, when the interlock driving mechanism 34 of the first supply hopper 30 is driven by the control unit 70, the upper shutter 32 and the lower shutter 33 are alternately opened and closed. Thereby, the lowermost first blister package 1A sequentially falls from the package stack 2A accommodated in the first supply hopper 30 one by one.

  Furthermore, when the interlock driving mechanism 44 of the second supply hopper 40 is driven by the control unit 70, the upper shutter 42 and the lower shutter 43 are alternately opened and closed. Thereby, the lowermost second blister package 1B sequentially falls one by one from the package stack 2B accommodated in the second supply hopper 40.

  By operating the feeding device 20, the first supply hopper 30, and the second supply hopper 40 as described above, the first blister package 1A and the second blister package 1B are pushed by the push finger 24 as follows. , Stacked (see FIG. 8).

  First, before the pushing finger 24 reaches under the guide 31 of the first supply hopper 30, one first blister package 1A falls from the first supply hopper 30 and is received by the transport base 13 (FIG. 8A). reference). When the first blister package 1A is dropped, the first blister package 1A is guided by the guide plates 11L and 11R, so the first blister package 1A is tilted around the vertical axis, the longitudinal axis, and the vertical axis. In addition, the landing position of the first blister package 1A on the transport table 13 is a desired designed position.

  Regarding the orientation of the first blister package 1A that has fallen, the back surface of the first blister package 1A (the surface on the side where the convex storage portion 6 is recessed) is directed downward, and The front surface (the surface on which the convex storage portion 6 protrudes) is directed upward, the first flange portion 8 is directed rearward, and the second flange portion 9 is directed forward.

  Thereafter, the push finger 24 passes forward under the guide 31 of the first supply hopper 30, whereby the first blister package 1 </ b> A that has fallen on the transport table 13 is pushed by the push finger 24 and conveyed forward. . At this time, the front surface 24a of the push finger 24 comes into contact with the end of the first flange portion 8 of the first blister package 1A. Since the first blister package 1A is guided by the guide plates 11L and 11R during the conveyance of the first blister package 1A, the first blister package 1A does not fall left or right from the conveyance table 13.

  Thereafter, when the first blister package 1A reaches the front end of the transport table 13, it falls onto the transport table 15 (see FIG. 8B). Thereafter, the first blister package 1 </ b> A is conveyed forward on the conveying table 15 by the push finger 24. Since the first blister package 1A is guided by the guide plates 11L and 11R during the conveyance of the first blister package 1A, the first blister package 1A does not fall left or right from the conveyance table 15.

  Before the push finger 24 reaches under the guide 41 of the second supply hopper 40, one second blister package 1B falls from the second supply hopper 40 and is received by the carrier 14 (see FIG. 8C). . When the second blister package 1B is dropped, the second blister package 1B is guided by the guide plates 11L and 11R, so that the posture and the landing position of the second blister package 1B are stabilized.

  Regarding the orientation of the dropped second blister package 1B, the front (front) surface of the first blister package 1A (the surface on the side from which the convex storage portion 6 protrudes) is directed downward. The back surface of the blister package 1A (the surface on which the convex storage portion 6 is recessed) is directed upward, the first flange portion 8 is directed forward, and the second flange portion 9 is directed rearward.

  Thereafter, when the feeding finger 24 passes forward under the guide 41 of the second supply hopper 40, the second blister package 1 </ b> B that has fallen on the conveyance table 14 is pushed by the feeding finger 24 and conveyed forward. . At this time, it abuts on the front surface 24a of the push finger 24 and the end of the second flange portion 9 of the second blister package 1B.

  As described above, the end portion on the upstream side in the transport direction of the second blister package 1B and the end portion on the upstream side in the transport direction of the first blister pack 1A are aligned in the front-rear direction by the front surface 24a of the push finger 24, The second blister package 1B and the first blister package 1A are conveyed in parallel. At this time, the convex storage portion 6 of the second blister packaging body 1B is shifted rearward from the convex storage portion 6 of the first blister packaging body 1A by one body of the convex storage portion 6, and the second blister packaging body. The convex storage part 6 of 1B exists above the position between the convex storage parts 6 of the blister package 1. During the conveyance of the blister package 1A, 1B, the blister package 1A, 1B is guided by the guide plates 11L, 11R.

  Thereafter, when the second blister package 1B reaches the front end of the transport table 14, the second blister package 1B overlaps the first blister package 1A (see FIG. 8D). At this time, the convex storage portion 6 of the upper second blister package 1B fits between the convex storage portions 6 of the lower first blister package 1A.

  Thereafter, the blister packs 1A and 1B are transported forward on the transport table 15 in a stacked state and supplied to downstream equipment. And blister package 1A, 1B is processed by downstream equipment.

When the downstream device is a packaging machine, the stacked blister packaging bodies 1A and 1B are packaged by the packaging machine. Accordingly, one package includes one first blister package 1A and one second blister package 1B.
When the downstream device is a stacking device, a plurality of sets of the blister packaging bodies 1A and 1B may be stacked by a stacking device, and a plurality of sets of the blister packaging bodies 1A and 1B may be combined. For example, when two sets of blister packs 1A and 1B are stacked, the stack includes two first blister packs 1A and two second blister packs 1B.

4). Effect As described above, the first blister package 1A dropped by the first supply hopper 30 has the convex storage portion 6 facing upward, the second flange portion 9 facing forward, and the first flange portion 8. Is backwards. On the other hand, in the second blister package 1B dropped by the second supply hopper 40, the convex storage portion 6 is facing downward, the first flange portion 8 is facing forward, and the second flange portion 9 is facing backward. The first blister package 1A and the second blister package 1B are run forward by the push finger 24. At this time, the convex storage portion 6 of the first blister package 1A is the same as that of the second blister package 1B. The convex storage portion 6 is shifted forward by one convex storage portion 6. Therefore, when the first blister package 1A and the second blister package 1B are conveyed to the front end of the conveyance table 14, the convex storage portion 6 of the upper second blister package 1B is the lower first blister. It enters between the convex storage portions 6 of the package 1A. Accordingly, the overall height of the stacked blister packs 1A and 1B can be reduced.

  By causing the first blister package 1 </ b> A dropped by the first supply hopper 30 and the second blister package 1 </ b> B dropped by the second supply hopper 40 to run side by side with the push finger 24, the second blister package 1 </ b> B. Are stacked on the first blister package 1A, and the convex storage portion 6 of the second blister package 1B is fitted between the convex storage portions 6 of the first blister package 1A. That is, in this embodiment, the second blister package 1B is not directly dropped onto the first blister package 1A being conveyed. Therefore, the second blister package can be obtained without super-precision synchronous control of the interlocking drive mechanism 34 of the first supply hopper 30, the interlocking drive mechanism 44 of the second supply hopper 40, and the transport motor 22 of the pusher device 20. These blister packaging bodies 1A and 1B can be stacked so that the convex housing section 6 of 1B is fitted between the convex housing sections 6 of the first blister packaging body 1A.

  Since the conveyance stand 13 is provided between the conveyance stand 15 and the first supply hopper 30, the drop distance of the first blister package 1A dropped by the first supply hopper 30 is short. Therefore, even if the period from when the pushing finger 24 passes under the first supply hopper 30 to the downstream side until the next pushing finger 24 passes under the first supply hopper 30 to the downstream side is dropped, it falls. The first blister package 1 </ b> A can be reliably captured by the push finger 24. Therefore, the stacking apparatus 100 can be operated at a high speed, and a large number of blister package bodies 1A and 1B can be formed in a short time.

  Since the drop distance of the first blister package 1A dropped by the first supply hopper 30 is short, the landing position of the first blister package 1A on the transport table 13 tends to be a desired design position. Therefore, the dropped first blister package 1 </ b> A can be reliably captured by the push finger 24.

  Blister packages 1A and 1B can be stacked and stored in cavities 31a and 41a surrounded by guides 31 and 41, respectively. Therefore, even if the replenishing device for replenishing the supply hoppers 30 and 40 with the blister packs 1A and 1B is temporarily stopped, the blister packs can be used as long as the operation states of the supply hoppers 30 and 40 and the feeding device 20 continue. 1A and 1B can be stacked. Further, even if the pushing device 20 is temporarily stopped, the blister packs 1A and 1B can be replenished into the cavities 31a and 41a surrounded by the guides 31 and 41 if the operating state of the replenishing device continues. it can.

5. Modifications As mentioned above, although the form for implementing this invention was demonstrated, embodiment mentioned above is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof. Changes from the above embodiment will be described below. The changes described below may be applied in combination as much as possible.

(1) The transport table 13 in the above embodiment may not be provided. In this case, the first blister package 1 </ b> A dropped by the first supply hopper 30 is received by the transport table 15. The lower end opening of the cavity 31a surrounded by the guide 31 of the first supply hopper 30 is located below the lower end opening of the cavity 41a surrounded by the guide 41 of the second supply hopper 40, and the first supply hopper 30 The fall distance from the transport table 15 to the transport table 15 is shortened.

(2) As shown in FIG. 9, in addition to the change of (1) above, the pusher 20 is changed as follows. The driven sprocket 25 is located behind the first supply hopper 30 and the conveyance table 15 and below the conveyance table 15, and the installation position of the driven sprocket 25 is lower than the installation position shown in FIG. 4. A driven sprocket 26 is provided between the driven sprocket 25 and the drive sprocket 21 (see FIG. 4). The driven sprocket 26 is at a position above the driven sprocket 25 and at a position below the transport table 15. Further, the driven sprocket 26 is located between the first supply hopper 30 and the second supply hopper 40. An upper portion 23a of the endless chain 23 is hung on the driven sprocket 26 between the drive sprocket 21 and the driven sprocket 25, and a portion 23b between the driven sprocket 25 and the driven sprocket 26 is inclined.

  When the endless chain 23 is driven by the transport motor 22, the pushing finger 24 moves up when it moves from the driven sprocket 25 to the driven sprocket 26. Then, since the pushing finger 24 protrudes on the transport table 15 immediately before the first supply hopper 30, the first blister package 1A dropped from the first supply hopper 30 is pushed downstream by the pushing finger 24 in the transport direction. It is. When the push finger 24 moves under the first supply hopper 30 to the downstream side in the transport direction, the push finger 24 also moves up. When the push finger 24 reaches the driven sprocket 26, the push finger 24 protrudes on the transport table 14, so that the second blister package 1B dropped from the second supply hopper 40 is downstream in the transport direction by the push finger 24. Pushed to the side.

  As described above, when the driven sprockets 25 and 26 are provided, the pushing finger 24 that moves below the first supply hopper 30 toward the downstream side in the transport direction slightly protrudes upward from the transport base 15. Therefore, even if the first supply hopper 30 is installed below, the pushing finger 24 does not hit the first supply hopper 30.

(3) Reverse the direction of the plurality of first blister package bodies 1A accommodated in the first supply hopper 30 and further reverse the direction of the plurality of second blister package bodies 1B accommodated in the second supply hopper 40. You may let them.

  That is, the second flange portion 9 of the first blister package 1A accommodated in the first supply hopper 30 is directed rearward, the first flange portion 8 is directed forward, and the front (front) surface (convex) The surface on which the shape storage portion 6 protrudes) is directed upward. The second flange portion 9 of the second blister package 1B accommodated in the second supply hopper 40 is directed forward, the first flange portion 8 is directed rearward, and the front (front) surface (convex storage) The surface on the side from which the portion 6 projects is directed downward.

(4) The lower shutter 33 is interlocked between the time when the pushing finger 24 passes forward below the guide 31 of the first supply hopper 30 and the time when the subsequent pushing finger 24 reaches below the guide 31. It may be opened more than once by mechanism 34. In this case, a plurality of first blister packs 1A are sequentially dropped between the time when the pushing finger 24 passes forward under the guide 31 and the time when the subsequent pushing finger 24 reaches below the guide 31. Then, they are stacked on the transport table 13. Therefore, a plurality of first blister packs 1 </ b> A stacked on the transport table 13 are pushed by the push fingers 24.

  In addition, the lower shutter 43 is connected to the interlocking drive mechanism between the time when the pushing finger 24 passes forward under the guide 41 of the second supply hopper 40 and the next time when the succeeding pushing finger 24 reaches below the guide 41. 44 may be opened more than once. In this case, a plurality of second blister packs 1B are sequentially dropped between the time when the pushing finger 24 passes forward below the guide 41 and the time when the subsequent pushing finger 24 reaches below the guide 41. Then, they are stacked on the transport table 14. Therefore, a plurality of second blister packs 1 </ b> B stacked on the transport table 14 are pushed by the push fingers 24.

  In addition, the number of the 1st blister package 1A and the number of the 2nd blister package 1B which one feed finger 24 pushes may be equal, and may differ. For example, the following (4a) to (4b) may be used.

(4a) The push finger 24 pushes the two-stage first blister package 1A dropped by the first supply hopper 30, and then the push finger 24 is dropped by the second supply hopper 40. The two blister package 1B is fed together with the two-stage first blister package 1A. Then, when the pushing finger 24 passes downstream of the front end of the transport table 14, one second blister package 1B is stacked on the two first blister packages 1A.

(4b) The feeding finger 24 pushes the first-stage first blister package 1A dropped by the first supply hopper 30 and then the second-stage first blister package 40 dropped by the second feeding hopper 40. The two blister package 1B is pushed together with the first-stage blister package 1A. Then, when the pushing finger 24 passes downstream of the front end of the transport table 14, the two second blister package bodies 1B are stacked on the first blister package body 1A.

(5) When the downstream device is a stacking device, the total number of blister packs 1A and 1B of each set stacked by the stacking device may be different for each set. For example, the stacking device is a set of two second blisters in a set in which two second blister packs 1B and one first blister pack 1A are stacked (the number of sets is, for example, an odd set). A set in which the package 1B and one first blister package 1A are stacked (the number of sets is one or more) may be stacked.

(6) In the above embodiment, the entry position of the lower shutter 33 of the first supply hopper 30 is lower than the entry position of the upper shutter 32 by one stage of the first blister package 1A. On the other hand, the entry position of the lower shutter 33 may be lower than the entry position of the upper shutter 32 by a plurality of stages (for example, two stages) of the first blister package 1A. In this case, per one opening / closing operation of the lower shutter 33 by the interlocking drive mechanism 34, a plurality of (for example, two) first blister packs 1A are dropped in a state of being overlapped.

  Further, the entry position of the lower shutter 43 may be lower than the entry position of the upper shutter 42 by a plurality of stages (for example, two stages) of the second blister package 1B. In this case, per one opening / closing operation of the lower shutter 43 by the interlocking drive mechanism 44, a plurality of (for example, two) second blister packs 1B are dropped in an overlapping state.

  In addition, the number of the 1st blister package 1A which the one feed finger 24 pushes, and the number of the 2nd blister package 1B may be equal, and may differ. For example, it may be as described in (4a) to (4b) above.

(7) In the blister package 1 of the above embodiment, the first flange portion 8 extends from the top 6a of the row of the convex storage portion 6, the second flange portion 9 extends from the end 6b of the row, The one flange portion 8 is longer than the second flange portion 9 (see FIG. 1). On the other hand, as shown in FIG. 10, the distance L3 from the head 6a of the row of the convex storage portions 6 to the end of the first flange portion 8 is the second flange portion from the tail 6b of the row of the convex storage portions 6. It may be equal to the distance L4 to the end of 9.

  In this case, as shown in FIGS. 11A and 11B, a notch is formed in the upper part of the front surface of the push finger 24. Accordingly, the front surface of the push finger 24 is formed in a step shape so that a portion 24b protruding above the conveyance table 14 and a portion 24c between the conveyance table 14 and the conveyance table 15 are displaced in the conveyance direction. Yes. The step between the upper part 24 b and the lower part 24 c on the front surface of the push finger 24 is substantially equal to the length L of the convex storage part 6 along the long side direction of the thin plate part 5. Therefore, the convex storage portion 6 of the first blister package 1 </ b> A that is pushed by the lower part 24 c of the front surface of the push finger 24 on the carrier table 15 is moved by the upper part 24 b of the front surface of the push finger 24 on the carrier table 14. The second blister package 1B to be fed is displaced forward by one body of the convex storage section 6 from the convex storage section 6 (see FIG. 10A). When the blister package 1A, 1B is transported in this state and the second blister package 1B reaches the front end of the transport table 14, the second blister package 1B overlaps the first blister package 1A (FIG. 10B). At this time, the convex storage portion 6 of the upper second blister package 1B fits between the convex storage portions 6 of the lower first blister package 1A.

(8) The pushing finger 24 may circulate by a driving mechanism other than the chain driving mechanism (the driving sprocket 21, the driven sprocket 25, the conveyance motor 22, and the endless chain 23). For example, the plurality of pushing fingers 24 may be rotated by being independently driven by a linear motor (for example, refer to the technique described in Japanese Patent Application Laid-Open No. 2017-071479). In this case, an elliptical (oval shape) guide that is substantially the same as the shape of the endless chain 23 shown in FIG. 4 or FIG. 9 is provided below the carriage 15 and the pushing finger 24 is attached to the guide. Is guided in the circumferential direction along the guide.

(9) In the said embodiment, as shown in FIG. 2, by using the accumulation | stacking apparatus 100, one blister package 1A is set to a long side direction (conveyance direction) relatively with respect to the other blister package 1B. I shifted. On the other hand, as shown in FIG. 12, one blister package 1 </ b> A may be shifted relative to the other blister package 1 </ b> B in the short side direction (perpendicular to the conveying direction). In particular, when the interval P between the circular convex storage portions 6 is less than the length L of the convex storage portion 6, one blister packaging body 1A is relatively long in the long side direction with respect to the other blister packaging body 1B. At least one half blister package 1A is shifted with respect to the other blister package 1B after being shifted by at least half of the convex storage portion 6 and less than one, and perpendicular to the conveying direction. In the direction) by half or more and one or less of the convex storage portion 6. In the case shown in FIG. 12, the shape of the convex storage portion 6 is hemispherical, but may be another three-dimensional shape.

  Specifically, the following configurations (9a) to (9c) are adopted.

(9a) FIG. 13 is a cross-sectional view showing a changed portion. The position of the cut surface in FIG. 13 is the same as the position of the cut surface in FIG. As shown in FIG. 13, the lower conveyance table 15 (however, the portion behind the front end 14 c of the conveyance table 14) is inclined downward to the right with respect to the horizontal plane, and is forward of the front end 14 c of the conveyance table 14. Is twisted and leveled. Then, when the first blister package 1A that has fallen on the conveyance table 15 is pushed forward by the push finger 24, the first blister package 1A is shifted to the right side on the conveyance table 15 by its own weight, and the right guide Abuts on the plate 11R.

  On the other hand, the upper carrier 14 tilts downward to the left with respect to the horizontal plane. Then, when the second blister package 1B that has fallen on the conveyance table 14 is pushed forward by the push finger 24, the second blister package 1B is shifted to the left side on the conveyance table 14 due to its own weight, and the left guide Abuts on the plate 11L.

  By the above, in the state which 1A of 1st blister package bodies 1A shifted | deviated by one of the convex storage parts 6 in the short side direction (left-right direction) relatively with respect to the 2nd blister package body 1B, these blister package bodies 1A. , 1B are conveyed in parallel. Thereafter, when the second blister package 1B reaches the front end 14c of the transport table 14, the second blister package 1B overlaps the first blister package 1A. At this time, the convex storage portion 6 of the upper second blister package 1B fits between the convex storage portions 6 of the lower first blister package 1A (see FIG. 12). Thereafter, the blister packs 1 </ b> A and 1 </ b> B to be fed are in a horizontal posture due to the twist of the transport table 15.

  In addition, the conveyance stand 14 may incline to the right and the conveyance stand 15 may incline to the left. Moreover, the conveyance stand 14 may be horizontal and the conveyance stand 15 may incline to the left downward or the right downward. Further, the transport table 14 may be inclined to the left or the right and the transport table 15 may be horizontal.

(9b) When the blister packs 1A and 1B are guided downstream in the transport direction by the guide plates 11L and 11R, the first blister pack 1A and the second blister pack 1B are convexly stored by the guide plates 11L and 11R. Only one portion 6 is relatively shifted to the left and right.

  For example, as illustrated in FIG. 14, portions 11La and 11Ra extending upward from the conveyance table 14 of the portions on the downstream side of the second supply hopper 40 of the guide plates 11L and 11R are inclined to the right. Therefore, when the second blister package 1B that has fallen on the transport table 14 is pushed forward by the push finger 24, the second blister package 1B is placed on the transport table 14 by the portions 11La and 11Ra of the guide plates 11L and 11R. Lean to the right side of.

  On the other hand, among the portions of the guide plates 11L and 11R that are downstream of the second supply hopper 40, the portions 11Lb and 11Rb that extend downward from the conveyance table 14 are vertical, and the region 11Rb is the portion of the conveyance table 14. There is a break at the front end 14c. Therefore, when the 1st blister package 1A which fell on the conveyance stand 15 is pushed forward by the pushing finger 24, the 1st blister package 1A does not shift to right and left.

  By the above, in the state which 1A of 1st blister package bodies 1A shifted | deviated by one of the convex storage parts 6 in the short side direction (left-right direction) relatively with respect to the 2nd blister package body 1B, these blister package bodies 1A. , 1B are conveyed in parallel. Thereafter, when the second blister package 1B reaches the front end of the transport table 14, the second blister package 1B overlaps the first blister package 1A. At this time, the convex storage portion 6 of the upper second blister package 1B fits between the convex storage portions 6 of the lower first blister package 1A (see FIG. 12).

  A portion 11Rc on the downstream side in the transport direction from the front end 14c of the transport table 14 in the guide plate 11R extends downstream from the portion 11Ra in the transport direction and is disposed on the right side of the transport table 15.

(9c) As shown in FIG. 15, the convex storage portion 6 of the blister packs 1 </ b> A and 1 </ b> B has a position in the left-right direction of the second supply hopper 40 that is higher than the position in the left-right direction (lateral direction) of the first supply hopper 30. It is shifted to the right by one piece. Therefore, the first blister package 1A and the second blister package 1B are shifted laterally and dropped. Then, the first blister package 1A on the transport table 15 is displaced by one convex storage portion 6 in the short side direction (left-right direction) relative to the second blister package 1B on the transport table 14. In such a state, the blister packs 1A and 1B are conveyed in parallel. Thereafter, when the second blister package 1B reaches the front end of the transport table 14, the second blister package 1B overlaps the first blister package 1A. At this time, the convex storage portion 6 of the upper second blister package 1B fits between the convex storage portions 6 of the lower first blister package 1A (see FIG. 12).

  Here, since the extension length of the first flange portion 8 of the blister package 1A, 1B shown in FIG. 12 is longer than the extension length of the second flange portion 9, the configuration as in the above (9a) to (9c) By adopting in combination with the above embodiment, the blister package 1A, 1B is stacked as shown in FIG. On the other hand, when the extension length of the first flange portion 8 of the blister package 1A, 1B is equal to the extension length of the second flange portion 9, the feeding finger whose front surface is stepped as in (7) above. 24 and the above configurations (9a) to (9c) are used in combination.

(10) When the configuration as described in (9a) to (9c) above is adopted, the supply hopper 30, around the vertical center line of the supply hopper 30, 40 without changing the installation position of the supply hopper 30, 40.
