ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to an apparatus (gear mechanism) for producing essentially rectilinear, in particular reciprocating movements of linear elements, preferably carry-along elements, pushers or the like for pushing articles—a cigarette block—into a pocket of a folding turret.
An important application area of a gear mechanism for producing linear movements is the introduction of the pack contents, namely of a cigarette block, into the pocket of a folding turret or into a partially completed blank for the (cigarette) pack. In the case of a known apparatus (DE 24 62 686), the cigarette block is gripped, on a movement path directed radially in relation to the folding turret, on the rear side by an angled pusher and is pushed into the pocket of the folding turret or into the pack. The pusher can be displaced as a pivotable lever with a sliding piece on a fixed guide rod. The reciprocating drive is executed by a crank.
Such a gear mechanism is problematic for very high cycle speeds on account of the reciprocating movement.
SUMMARY OF THE INVENTION
The object of the invention is to propose an apparatus or a gear mechanism by means of which, even at high cycle speeds, reciprocating linear elements, namely in particular carry-along elements, pushers, etc., move continuously and smoothly to transport articles, in particular to push cigarette blocks into a folding turret, and then to return into the starting position in an—offset—return—movement path.
In order to achieve this object, the apparatus according to the invention is characterized in that the linear element—carry-along element, pusher or the like—can be moved by gear-mechanism elements which execute exclusively rotary movements.
The gear mechanism according to the invention is configured such that the rotary movements of the drive elements are converted into a reciprocating movement of the linear element. The movement sequence as a whole is thus round.
In a preferred embodiment, the gear mechanism comprises a drive element which circulates along an arc of a circle, namely in particular a circulating gear wheel, which rotates about its own axis and is connected to the carry-along element, pusher or the like via a connecting element, in particular via a lever. The lever is fitted on the drive element, namely on the gear wheel, in a fixed position relative thereto and is connected to the carry-along element or a carry-along arm via a rotary bearing.
In the case of a preferred, specific embodiment of the gear mechanism, the drive element runs, as gear wheel, on a fixed toothed rim with an inner toothing arrangement. The lever, which is connected to the gear wheel in a fixed position relative thereto, is connected, via an intermediate gear mechanism or a mating gear mechanism, to the linear element or a carrying arm for the purpose of transmitting the linear movements to the carry-along element or pusher. Parts of the intermediate gear mechanism or mating gear mechanism are controlled in terms of movement such that return movement of the linear element takes place in an offset movement path, in particular above the linear advancement movement. For this purpose, the movement of a pivotable cam lever is controlled via cam rollers in a grooved curve during the rotary movement.
Further details and features of the apparatus according to the invention are explained in more detail hereinbelow with reference to an exemplary embodiment and application example. In the drawings:
