DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be specifically described with reference to the embodiments shown in the drawings.

The device 10 for operating the blister sheet 1 shown in FIG. 1 is a component of a packaging machine for producing and packaging the blister sheet 1 containing tablets, dragees or the like. . This device 10 is connected to a punching device 10,
Within, the sheet web composite (Foeinbahnve)
rbund) 2 simultaneously, two blister sheets 1 arranged side by side as viewed in the feed direction 12 of the sheet web composite 2 can be punched out. On the lower side of the punching device 11 and in the area of the device 10,
A number of containers 13 are arranged for discharging partially filled or soiled blister sheets 1 and others. By means of the device 10, the two blister sheets 1, each punched by the punching device 11, are superimposed on one another at their plurality of projections 3 (tied together), and the walls 15 of the grouping device 16 forming the pockets 14. Between which a blister sheet 1 or blister sheet pair 4 is mounted in a subsequent cartoning device (Karoniereinrichtun)
g).

The apparatus 10 has three successively arranged suction rotors 17, 18 and 19, each rotating in a clockwise direction about a horizontal rotation axis, for conveying the blister sheet 1. ing. The two suction rotors 17 and 18 are configured as double suction rotors, and the two groups 21 and 22 have three suction arms 23 arranged at the same angular intervals in the illustrated embodiment. In contrast, the third suction rotor 19 is arranged on the side of the grouping device 16 and is aligned with this grouping device 16 and has three suction arms 23.
It is configured as a single suction rotor having only one group 24. Groups 21, 22 adapted to the arrangement of the blister sheets 1 in the sheet web composite 2
The spacing of 2 is possible by the arrangement of the suction arms 23 on the respective shafts 25 of the suction rotors 17,18. The blister sheet 1 is fed from the punching device 11 to the grouping device 16 by the suction rotors 17, 18, 19 or their suction arms 23. The holding and transfer of the blister sheet 1 from one suction rotor to the other suction rotors 17, 18, 19 accordingly controls the negative pressure in at least one adsorber for the suction arm 23 with each blister sheet 1. This is done by: This process is generally known and is not important to the present invention and is therefore not disclosed in DE-A-196 484.
See No. 47.

On the upper side of the suction rotor 17, two monitoring devices configured as cameras 26 are arranged, and these monitoring devices are respectively directed toward the camera 26 when the suction arm 23 rotates. The blister sheet 1 is optically detected and the accuracy of the filling and intactness of the projections 3 is checked. On the upper side of the suction rotor 18, the first
And a second supply shaft 28 in which the blister sheet 1 is accommodated is disposed above the suction rotor 19. In order to compensate for the blister sheet 1 which has previously been recognized as a defective blister sheet by the camera 26 and has been discharged, a good blister is respectively supplied from these supply shafts 27, 28 by the suction rotors 18, 19 or the suction arm 23, respectively. The sheet is taken off.

Almost below the two suction rotors 18, 19, another transport device 30 for the blister sheet 1 is provided.
Is extending. This further transport device 30 is configured as a conveyor belt with toothed belts 31, 32 arranged parallel to one another and connected to one another. Outside the toothed belts 31, 32, lateral guides (transverse traverses) 35 arranged in parallel with each other with a uniform interval.
Has been fixed. As shown in FIG. 2, each lateral guide 35 is configured as a tube 36 with a longitudinal notch 37 therethrough. Both ends of the tube 36 protrude into tightening members 38, 39 connected to the toothed belts 31, 32. Holes 41, 42, 43 that open to each other are formed in one of the tightening members 39, and the hole 41 among these holes is connected to the longitudinal notch 37.
A telescopic suction unit 44 protrudes into another hole 43, and the telescopic suction unit 44 is connected to another toothed belt 46.

The toothed belt 46 is a toothed belt 3
1 and 32 and are driven at the same speed as the toothed belts 31 and 32. The lower side of the toothed belt 46 covers the upper side of a stationary suction strip 47 connected to a negative pressure source in a form-locking (binding by shape) manner. In the suction strip 47, a longitudinal hole 48 is provided.
And a longitudinal slit 49 opening below the toothed belt 46. The longitudinal slit 49 is
It cooperates with a through hole 51 formed in the toothed belt 46.
Since this through-hole 51 is aligned with the telescopic adsorber 44, the negative pressure generated by the negative pressure source causes the longitudinal hole 48, the longitudinal slit 49, the telescopic adsorber 44 and the lateral Notch 37 in longitudinal direction of guide 35
It acts via holes 41, 42, 43 formed in the inside.

A carriage 52 for transporting one blister sheet 1 is slidably disposed on each lateral guide 35. The carriage 52 with the elongated base body 50 surrounds the lateral guide 35 with play except for the edge area of the lateral guide 35, so that a hollow space is provided between the base body 50 and the lateral guide 35. 54 are formed. In contrast, the edge region 53
Surrounds the lateral guide 35 without play, i.e., on the one hand, allows sliding guidance of the carriage 52 on the lateral guide 35, on the other hand, the hollow space 54 is sealed to the outside.

A cam roller 55 is provided above the carriage 52.
The cam rollers 55 cooperate with guides 56 associated with the size of the blister sheet to move the carriage 52 upwardly in its main feed direction 57 when the toothed belts 31, 32 circulate. Is slid in the feed direction 58 at right angles to. An adsorber 60 for holding the blister sheet 1 is disposed above the carriage 52, and the adsorber 60 is connected to the hollow chamber 54. Further, since the hollow chamber 54 is connected to the longitudinal notch 37 of the lateral guide 35 through a hole 61 provided in the lateral guide 35, the negative pressure generated by the negative pressure source Direction notch 37, hole 61 and hollow chamber 5
4 and acts on the adsorber 60. What is important is that the hollow chamber 54 and the hollow chamber 54 and thus the adsorber 6 extend over the entire sliding path of the carriage 52 on the lateral guide 35.
0 is always connected to the hole 61.

As described above, the guide 56 is configured according to the size of the blister sheet. This configuration means that when the adsorber 60 is located below the suction rotor 18, it is aligned with the suction arm 23 of the group 22 of the suction rotor 18 or is arranged in the same row. It is. Then, as the toothed belts 31, 32 circulate, the adsorber 60 is moved (not in the main feed direction 57) until it is located below the suction rotor 19 and is aligned with the suction arm 23 of this suction rotor. ) Move in the feed direction 58.

Advantageously, the toothed belts 31, 32 each have one common axis of rotation 62, 63 and are connected to a common drive. While the guide 56 can adapt the sliding movement of the adsorber 60 to the length and width of the blister sheet size, it is further necessary to adapt the device 10 to different sizes associated with different projections. To this end, the toothed belt 31,
32 can be pivoted about its common axis of rotation 62.
The rotating shaft 63 directed sideways moves up or down accordingly. Thus, for example, when the rotating shaft 63 is lowered, the suction device 60 also keeps the suction rotor 1 at a relatively large distance from the rotating shaft of the suction rotor 19.
9 at the pick-up position.

The blister sheets 1 superimposed on each other in a reverse direction are surely guided to form a grouping device 1.
A specially configured insertion finger 65 is provided in order to be able to transfer to 6. As shown in FIG. 1, the insertion finger 65 is disposed between the guide 56 and the toothed belt 31. FIG. 3 shows, as a first variant, an insertion finger 65 arranged on the rotary shaft 63, in which the lateral guide 35 is omitted for clarity. According to FIG.
The guide 66 is connected to the grouping device 16 with substantially no gap, and the guide 66 is aligned with the lower wall 15 of the pocket 14 of the grouping device 16. The holder 67 is arranged on the two blister sheets 1 which are arranged on the upper wall portion 15 of the pocket 14 and overlapped with each other in the opposite direction. The number of insertion fingers 65 arranged on the rotating shaft 64 is matched to the diameter of the rotating shaft 64 and the distance between the lateral guides 35, and the two blister sheets 1, which are overlapped in the opposite direction to each other, form one set. At the time of insertion, at least one insertion finger 65 is in each case operatively connected to the blister sheet 1. Since the contact surface 68 of the insertion finger 65 that comes into contact with the blister sheet 1 is formed in the shape of an involute curve, a thrust force acting in the main feed direction 57 is generated on the blister sheet 1. Blister sheet 1 and contact surface 68
Only the downwardly acting frictional force generated due to the friction between the blister sheet 1 against the guide 66.

In the second embodiment shown in FIG. 4, the insertion finger 65a is arranged on a toothed belt 69 that circulates endlessly. This toothed belt 69 is likewise arranged between the toothed belt 31 and the guide 56.

The apparatus 10 operates as follows. By means of the suction arm 23 of the first suction rotor 17, each two blister sheets 1 arranged side by side are taken out of the punching device 11 at the same time,
It is delivered to the second suction rotor 18. Then
Second suction rotor 1 assigned to group 22
8 puts the blister sheet 1 on the carriage 52, whereas the suction arm 23 of the second suction rotor 18, assigned to the group 21, puts the blister sheet 1 on the third suction rotor. Hand over to 19. While the blister sheet 1 is being conveyed from the second suction rotor 18 to the third suction rotor 19, the lower side of the blister sheet 1 placed on the adsorber 60 of the carriage 52 by the second suction rotor 18 becomes the third Since the blister sheet is positioned below the suction rotor 19, two blister sheets can be held together in a pair. Thus, the blister sheet 1 transferred to the third suction rotor 19 by the second suction rotor 18 on the blister sheet 1 is arranged such that the projections of the two blister sheets 1 face each other and are shifted laterally. So that they are tied together.
The blister sheets 1 forming one blister sheet pair superimposed on one another are then inserted into the insert fingers 65.
Or 65a into the pocket 14 of the grouping device 16 and then the next blister sheet 1
Is moved forward one position to pick up the.

The apparatus 10 has a transport device 30 which is driven periodically or continuously. However, in the case of the continuously driven transfer device 30, it is necessary to adjust the movement path of the suction rotors 18 and 19 to the continuous movement of the carriage 52 in the main feed direction 57. This is because the suction rotors 18, 19 make a cycloidal movement when the blister sheet 1 is delivered to the transport device 30, that is, an additional horizontal motion component (the transport of the transport device 30 in the main feed direction 57). (Depending on speed). The device 10 can be varied in various ways without departing from the spirit of the invention. For example, it is also conceivable to provide an additional suction rotor in an additional section between the punching device 11 and the grouping device 16 and to continue this suction rotor directly to the punching device 11. Furthermore, more than two blister sheets 1 in the sheet web composite 2
, The suction rotor may have many groups of suction arms, respectively. In this case, for example, it is also conceivable to provide additional transport devices 3 arranged parallel to one another.
