DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blister packaging sheet (hereinafter referred to as a "PTP sheet"), and more particularly, to a plurality of PTP sheets in which pocket portions face each other and a predetermined relative positional relationship is maintained. The present invention belongs to a technical field including a PTP sheet tying and conveying device for conveying the state to a next packaging device or the like.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 12, a PTP sheet 1 is provided with a plurality of pockets 2 for accommodating tablets and the like, and can be cut into sheet pieces 3 of each pocket 2 unit. A vertical slit 4 and a horizontal slit 5 are formed at the bottom. Further, a tag section 6 on which identification information such as a lot number is engraved is attached to an end of the PTP sheet 1.

[0003] The PTP sheet 1 has a process of feeding tablets into the pocket portion 2 while transferring a long film having the pocket portion 2 formed thereon, a process of attaching a cover film made of aluminum or the like, 5 and a step of punching out one PTP sheet. Then, the plurality of PTP sheets 1 continuously sent through the above-described steps are supplied to, for example, a packaging step (including sealing and boxing).

[0004] At the stage before the packaging is performed, a “tying step” is performed to minimize the total volume of the PTP sheets 1 stacked in a plurality of stages. That is, as shown in FIG. 13 to FIG.
The sheet 1 is overlapped so that the pockets 2 face each other, and the sheet 1 is subjected to a step of tying the sheets 1 in a state where the sheets 1 are shifted from each other by a predetermined amount so that the upper and lower pockets 2 do not collide with each other. Then, the pair of upper and lower PTP sheets 1 thus tied together is stacked in a predetermined set (for example, 5 sets), and is supplied to the next packaging step. In the above-described tying step, a tying transport device as described below is used.

[0005] The tying transport device includes, for example, a reversing device and a position adjusting transport device. The reversing device sequentially converts the PTP sheet 1 conveyed while being directed in a certain direction (for example, with the pocket portion 2 facing downward),
(1) Sending with the upper and lower surfaces inverted, (2) Sending without turning the upper and lower surfaces and turning the direction,
The above (1) and (2) are alternately performed (every other sheet) to lead to the next step. In addition, the position adjusting device transport is a device in which two PTP sheets 1 sent from the reversing device are arranged in a state of being tied up and down, and are sent by a conveyor (not shown) while relatively displacing the mutual positions. See Japanese Unexamined Patent Publication No. Hei 2-280203). In this position adjusting device, the positions are shifted from each other by claws provided on the conveyor, and then, the two are superimposed and fed by another claw provided on another conveyor. Such another claw pushes one of the upper and lower PTP sheets 1 (for example, the upper PTP sheet) of the PTP sheets 1 that are superimposed with their positions shifted from each other. At this time, since the upper and lower pockets 2 are engaged with each other, if one is pushed, the other will be sent following it.

[0006]

However, the above technique has the following problems. That is, due to the difference in shrinkage between the film and the cover film, the PTP sheet 1 is likely to be curled as shown in FIG. When the curl occurs in this way, the engagement between the pocket portions 1 is released or the amount of engagement is reduced, and when pressing with the another claw, both upper and lower sides are pressed instead of one. It will be. For this reason, even though the position adjustment was performed in the previous stage, the position adjustment became meaningless,
For example, there is a possibility that the subsequent steps may be hindered, such as an inability to expect efficient packaging.

Further, when the position adjusting / conveying device that conveys with the claw of the conveyor is used as described above, the mechanism at the lower part of the conveyor is very complicated due to the dense arrangement of shafts, pulleys, belts and the like. Becomes For this reason, if PTP
If the sheet 1 drops during conveyance, the sheet 1 may be bitten by a complicated mechanism, making it difficult to remove the sheet. In addition, because of the complicated mechanism as described above, in reality, it is desired to improve maintainability in maintenance of various members, replacement of parts, and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a plurality of PTP sheets stacked together at a predetermined position so that pocket portions face each other and transported to a next step.

The vertical stroke of the tip of the claw 61 is mainly determined based on the amount of eccentricity.

Further, in the present embodiment, when the PTP sheet 1 is guided to the upper slit 31 and when the PTP sheet 1 is guided to the lower slit 32,
The trajectories drawn by the claws 69 are different, that is, the claws 69
The front and rear strokes at the front end of the head are different from each other. More specifically, as shown in FIG. 5, a rotating shaft 71 that rotates at half the speed of the driving shaft 55 (for example, 100 rotations per minute) is separately provided.
The base end of the lever 72 is supported at a position eccentric from the first axis by a slight eccentric amount H. Further, the lever 72
Is connected to the driven shaft 61 side.

Therefore, for example, when the pawl 69 is at the forward end (the right end in the figure), the eccentricity of the lever 72 is on the left side of the figure (the support point of the lever 72 is Left side). Since the pawl 69 rotates (oscillates) at twice the speed of the rotating shaft 71, when the pawl 69 comes to the forward end in the next cycle, the eccentricity of the lever 72 comes to the right side of the drawing (the rotating shaft 71 is turned off). The support point of the lever 72 is on the right side with respect to the axis). For this reason, the forward end position of the claw 69 in a certain cycle,
With the forward end position of the claw 69 in the next cycle,
A difference of twice the eccentricity H can be generated.
Thus, as shown in FIGS. 7 and 8B, for example, the PTP sheet 1 guided by the upper slit 31 is
The paper is fed to a position advanced from the PTP sheet 1 guided by the lower slit 32, and the opposing pockets 2 are set at positions shifted from each other by a predetermined amount.

In the present embodiment, the eccentricity can be adjusted appropriately. For example, when the pawl 69 is at the forward end (the right end in the figure), the eccentricity of the lever 72 is on the lower side of the figure (the support point of the lever 72 is on the lower side of the figure with respect to the axis of the rotating shaft 71). ). Since the pawl 69 rotates (oscillates) at twice the speed of the rotating shaft 71, when the pawl 69 comes to the forward end in the next cycle, the eccentricity of the lever 72 comes to the upper side in the figure (the eccentricity of the rotating shaft 71). The support point of the lever 72 is on the upper side with respect to the axis.) Therefore, the forward end position of the pawl 69 in a certain cycle is substantially the same as the forward end position of the pawl 69 in the next cycle, and there is almost no difference in the feed amount.
In this way, by appropriately adjusting the eccentricity, the feed position of the PTP sheet 1 guided by the upper slit 31,
The relative positional relationship with the feed position of the PTP sheet 1 guided by the lower slit 32 can be appropriately adjusted.

Next, the chuck feeding means 35 will be described. As described above, the chuck feeding means 35 is composed of two upper and lower PTPs held and set by the holder means 33.
This is for holding the sheet 1 in its relative positional relationship and sending it to the next device (stacking device 91) in a predetermined tying state. As shown in FIG. 10, the chuck feeding means 35 includes a drive shaft 73 and an index 74 that rotates with the rotation of the drive shaft 73. The drive shaft 73 is connected to an intermittent drive mechanism, and is basically driven intermittently at a predetermined angle (about 90 degrees).

The index 74 has a plurality of (four) fixed claws 7 formed at equal intervals in the circumferential direction of the drive shaft 73.
5 is fixed. A slide base 76 is fixed to the index 74, and a movable claw 77 is slidably mounted on the slide base 76. The fixed claw 75 and the movable claw 77 constitute a chuck device 78 for holding the PTP sheet 1. The movable claw 77
Due to the tensile force of the coil spring 79 provided between itself and the fixed claw 75, the chuck device 78 is always pulled in the direction in which the chuck device 78 is closed (the direction in which the chuck device 78 approaches the fixed claw 75).

In this embodiment, the movable pawl 77
Is provided with a cam mechanism for appropriately sliding in the opening and closing directions. That is, as shown in FIGS. 10 and 11A, a cam 81 is provided to the drive shaft 73 via a bearing mechanism. On the other hand, the index 74 is provided with rotary shafts 82 at four positions corresponding to the movable claws 77 at positions separated from the drive shaft 73 by a predetermined distance. A first lever 83 is attached to the rotating shaft 82, and a cam follower 84 that contacts the cam 81 is provided at the tip of the first lever 83. Further, a second lever 85 is attached to the rotating shaft 82, and a substantially distal end of the second lever 85 is in contact with a protruding portion 86 protruding from the movable claw 77. Accordingly, when the cam follower 84 rides on the protruding portion (cam nose) of the cam 81, the first lever 83 and the rotation shaft 82 rotate relatively, and accordingly, the second lever 85 rotates. I do. For this reason, the tip portion of the second lever 85 is
6, the movable claw 77 slides in the opening direction against the tensile force of the coil spring 79. The cam 81 is provided so as to be rotatable relative to the drive shaft 73 and has a profile as shown in FIG. 11B, and the chuck device 78 (movable claw 77) moves to the forward position ( The cam follower 84 starts to ride up after passing (right side position in the figure). Then, the opening amount W of the movable claw 77 starts to increase after passing the lower end position in the drawing, and thereafter, the opening amount W of the movable claw 77 becomes maximum until reaching the left position (receiving position) in the drawing. . Thereafter, the movable claw 77 starts to close rapidly,
The TP sheet 1 can be gripped.

Further, as shown in FIG. 1, when the chuck device 78 reaches the forward end position, the chuck feeding means 35 comprises a pair of upper and lower PTP sheets 1 held by the chuck device 78 in a state of being held together. To the next loading device 9
1 is provided. The feed mechanism 92 is provided with a rod 93, a claw 94, and the like, as in the case of the above-described setting means 34, and the tip of the claw 94 moves back and forth as indicated by a two-dot chain line in FIG. The PTP sheet 1 can be conveyed to the next stacking device 91 in a gripped state.

The next loading device 91 is provided in the vicinity of the forward end of the chuck device 78. In the stacking device 91, a pair of PTP sheets 1 held together by an upper guide and a lower guide (both not shown).
, A plurality of sets (for example, five sets) of PTP sheets 1 can be stacked.

Now, a procedure of tying the PTP sheet 1 shown in FIG. 12 and transporting it to the stacking device 91 by the tying and transporting device 11 configured as described above will be described.

First, the PTP sheet 1 placed on the fin
Is fed by a feed mechanism 9 including a claw 7 and a rod 8 and the like.
The sheets are sent one by one to the reversing device 12. Reversing device 12
In, while the clamp device 21 is intermittently stopped in a state facing the receiving position (the left position in FIG. 2),
The PTP sheet 1 is inserted between the fixed claw 23 and the movable claw 24 with the pocket 2 down. Then, the operation of the slide mechanism 25 is released, and the movable claw 24 slides upward to clamp the PTP sheet 1.

At this time, the PTP sheet 1 is clamped on the basis of the fixed claw 23 on the upper side (in a stationary state). For this reason, the flat surface on which the pocket portion 2 is not provided comes into contact with the fixed claw 23 serving as a reference. Therefore, the flat surface of the PTP sheet 1 is used as a reference and is conveyed to the next step, and the reference side is not affected by the pocket portion 2 (the effect of the thickness). As a result, it is possible to guide the slits 31 and 32 of the holder means 33 accurately and reliably.

Next, when the drive shaft 14 rotates intermittently by about 90 degrees, the clamp device 21 comes to the receiving position on the fixed shaft 23, and the next PTP sheet 1 is clamped by the clamp device 21 in the same manner as described above. Is done. Then, the above operation is repeatedly performed.

When the clamp device 21 on the side of the rotating shaft 18 reaches the transfer position 180 degrees in the direction opposite to the receiving position, the clamp device 21 moves from the state facing the receiving position to the position of the rotating shaft 18 as described above. Since the PTP sheet 1 is rotated by 180 degrees around the axis, the PTP sheet 1 is not turned upside down, the pocket portion 2 remains down, and the tag portion 6 is turned 180 degrees in the opposite direction (direction). Is turned around). Then, from this state, the PTP sheet 1 with the pocket portion 2 facing downward is sent forward by the claw 69 of the setting means 34, and the holder 36L,
It is guided to the slit 31 on the upper part of 36R, 37L, 37R.

The clamp device 21 on the fixed shaft 19 side
Cannot rotate around the axis of the fixed shaft 19, so that when the delivery position is reached, the PTP clamped to it
The sheet 1 is turned upside down so that the pocket portion 2 faces upward, and the tag portion 6 has the same orientation as before. Then, from this state, the PTP in which the pocket portion 2 faces upward by the claw 69 of the setting means 34.
The sheet 1 is sent forward, and the holders 36L, 36R, 37
It is guided to the slit 32 below the L and 37R.

At this time, as described above, the pair of holders 36L, 36R, 37L, 37R are close to each other, and both sides of the PTP sheet 1 are held by the slits 31, 32. Further, the case where the PTP sheet 1 is guided to the upper slit 31 and the case where the lower slit 3
7 and FIG. 8B, when the PTP sheet 1 is guided to the second position, since the front and rear strokes of the claws 69 are different.
As shown in the figure, the PTP guided by the upper slit 31
The sheet 1 is guided by the lower slit 32 to the PT.
It is sent to a position advanced from P sheet 1 and,
The mutually facing pocket portions 2 are set at positions shifted by a predetermined amount. Further, at this time, the slits 31, 32
Is formed in a curved shape opposite to the curl direction of the PTP sheet 1, the curved portion acts as a resistance, and the excessive movement of the PTP sheet 1 is suppressed. Therefore, the PTP sheet 1 can be stopped and held at the originally planned position. In addition, since the degree of the eccentricity can be appropriately adjusted, the feeding position of the PTP sheet 1 guided by the upper slit 31 and the PTP sheet guided by the lower slit 32 according to the occasional needs. The relative positional relationship with the first feed position can be appropriately adjusted.

When the upper and lower PTP sheets 1 are guided by the slits 31 and 32, they are gripped by the chuck device 78 of the chuck feeding means 35.
At this time, the cam 81 is slightly rotated in the counterclockwise direction in FIG. As a result, the cam follower 84 riding on the cam nose is controlled to descend, so that the movable claw 77 relatively moves in the direction approaching the fixed claw 75.

At this time, since the fixed claw 75 side serves as a temporary reference (because it is in a state of being relatively immovable with respect to the movable claw 77 and not both movable), the structure is not complicated, and In addition, a structure for determining a reference at the time of chucking can be easily secured.

However, in the present embodiment, the movable pawl 77
Is relatively rotated in the closing direction, the drive shaft 73 and the index 74 are rotated about 3 degrees in the clockwise direction in FIG. Accordingly, with respect to the PTP sheet 1, the movable pawl 77 moves downward from above, and the fixed pawl 75 also moves upward from below by moving the index 74 about three times. It will come. Accordingly, the pair of upper and lower PTP sheets 1 are gripped by the movable claw 77 and the fixed claw 75 from both the upper and lower sides. For this reason, compared to the case where only the movable claw 77 is moved and the PTP sheet 1 is chucked, the PTP
The amount of deflection of the sheet 1 can be suppressed to half.

More specifically, the fixed claw 75 and the movable claw 77
In the case where the distance between them is, for example, “20 mm”, when only the movable claw 77 is chucked by sliding, the amount of deflection of the PTP sheet 1 is “20 m” at the maximum.
m ”(when the pocket portion 2 is not considered). On the other hand, in the present embodiment, the PTP sheet 1 is chucked by moving both the movable claw 77 and the fixed claw 75, so that the bending amount of the upper and lower PTP sheets 1 is "10 mm" (pocket) which is half of the maximum. (When the part 2 is not considered). For this reason, an adverse effect on the PTP sheet 1 due to an excessively large deflection amount can be suppressed. When the index 74 moves about three times, the holding of the pair of PTP sheets 1 by the fixed claw 75 and the movable claw 77 is completed.

At the time of chucking, the servo motor 44 is driven in reverse, and the ball screw 45 is turned in the opposite direction. Thereby, the paired holders 36L,
36R and the holders 37L, 37R move in the direction of opening (separating) each other, and the gripping state of the PTP sheet 1 is released.

Thereafter, the PTP sheet 1 gripped by the chuck device 78 in a state of being tied is conveyed toward the forward end as the index 74 rotates. The cam 8 follows the movement of the index 74.
1 also rotates clockwise by the amount of rotation. As a result, the cam 81 returns to the original position.

Then, when the PTP sheet 1 reaches the forward end position, the claw 94 of the feed mechanism 92 conveys the PTP sheet 1 in the holding state to the next stacking device 91 in a gripped state. In the next stacking device 91, a plurality of sets (for example, five sets) are stacked while a pair of PTP sheets 1 in a tied state are guided.
Then, it is provided to the next, for example, a packaging step.

As described above, according to the present embodiment, the pair of upper and lower PTP sheets 1 held in a predetermined relative positional relationship by the slits 31 and 32 of the holder means 33 remain in a predetermined tied state. It is sent to the next loading device 91. For this reason, even if the PTP sheet 1 is curled, there is no possibility that the mutually adjusted PTP sheets 1 are misaligned and conveyed. As a result, various inconveniences caused by the displacement can be prevented.

Further, unlike the prior art in which the conveyor is carried by the nails of the conveyor, in the present embodiment, the conveyor is not used as the carrying mechanism, so that the structure is simplified. In particular, even if the PTP sheet 1 falls to the lower part, there is no belt conveyor, pulleys for moving the belt conveyor, and the like at the lower part of the tying and conveying device 11, and various conveying members are not densely packed. The dropped PTP sheet 1 can be easily taken out. Moreover,
Maintenance of various devices, replacement of parts, and the like can be easily performed.

I decided to do it. On the other hand, in view of the above (a) and (b), it is not always necessary to perform (1) and (2) every other sheet. Therefore, for example, even if the upper and lower surfaces are configured to be sent twice consecutively, or the upper and lower surfaces are configured to be continuously inverted twice and the direction is inverted and sent. Good.

(D) Fixed claw 2 in clamp device 21
The positional relationship between 3 and the movable claw 24 may be opposite to each other.
