DEVICE FOR EXPRESSING BODIES FROM BLISTER PACKING

BOARDS j

Field of application, state of the art

The invention relates to a device for expressing]

a group of solid or semi-solid bodies from the blisters j

of blister pack boards. The solid body can be tablets,]

Dragees, capsules or other types of bodies such as screws, nails, \

Small parts or the like. When packing such |

Bodies occasionally experience errors, causing blister packs |

information boards are not completely filled or not completely |

are permanently sealed or the like. In these cases f

if the bodies packed therein are to be recovered, i

what has been done by hand so far. |

There are devices for pressing cheese out of foil | packs. The cheese is marked by a perforated, endless | Ribbon printed. However, such a device is not here | applicable since the packaged parts should not be destroyed |

Task, solution, advantages

The present invention is intended to provide a device of the initially specified named type created by which the fixed or semi-solid bodies can be removed from the blisters, with only the blister or at most the blister pack

panels are destroyed _3, on the other hand, the bodies should remain undamaged.

This object is achieved according to claim 1.

The blister pack panels are passed along the transport path between the two rotating bodies, the The cam of the one rotating body presses against the blister, thereby pushing the bodies contained therein into the gaps pushes between the circular disks of the other rotating body and thus pushes out of the blisters.

This device largely avoids manual labor, and the bodies to be expressed remain undamaged.

Developments of the invention

According to a development of the invention according to claim 2 is a shaft for feeding a stack of blister pack panels is provided, on which a conveyor device is located below that connects the blister packing panels transversely to the direction of fall in the shaft and along the above-mentioned transport path to the rotating bodies.

Preferably, according to claim 3, the Sacht are arranged vertically and the transport path horizontally.

While the first rotating body can be equipped with individual cams, a preferred embodiment according to claim $ is that a single cam extends over the entire working length of the first rotating body.

By further developments according to claims 5 or 6, the cam can either through an axially parallel recess of the first Rotary body arise or be designed so that it is opposite the main cross-section of the first rotary body protrudes.

Explanation of the invention

Embodiments of the invention are described below with reference to the drawings.

Fig. 1 shows a blister pack board which is used to hold pharmaceutical capsules or other objects can serve.

Fig. 2 is a schematic side view of a device according to the invention.

Figure 3 is a plan view of the same device.

Fig. 4 shows other embodiments of the rotating body with cams.

Fig. 1 shows a blister pack sheet 2, which is a plastic film with deep-drawn blisters 4 and in the usual manner has a metal foil sealed on its back. There are solid or semi-solid bodies 6 in the blisters, for example pharmaceutical capsules or smaller solid objects such as screws, nails or the like. With differently shaped Blisters can accommodate tablets / dragees or any other small bodies of other shapes. There are only two solid bodies 6 are shown.

The device for expressing the bodies has a vertical shaft 8 which holds a stack of blister pack panels 2 so that the blisters 4 point upwards. The sub-

On the right of the two rotating bodies there is a plate ^ k , the left side of which is provided with wide, parallel slots 36, so that prongs 38 remain, which are aligned with the circular disks 32.

As FIG. 4 shows, the first rotating body 26 'can also be designed in such a way that its cam 30 ^f protrudes on both sides. The cam can be rounded off for expressing semi-solid bodies.

function

The lowermost blister pack panel is pushed to the right by the conveying device from the more or less full shaft 8. The cam 30 or 30 ^{f of} the first rotating body 26 then presses approximately on the middle of a row of blisters 4. With further rotation it presses the bodies contained in the blisters down through the metal foil into the spaces between the circular disks 32, so that the bodies fall through between the prongs 38 below. The film remnants of the blister pack tables are pushed onto the prongs 38 and finally the plate 34 and from there by means not shown
removed.
