ABSTRACT:
The invention relates to a hand filling device for cigarette tubes, particularly for filter cigarette tubes with a tobacco press chamber extending in the longitudinal direction of the same, which is formed by a casing located in a base portion, a press head provided on the lid covering the casing and hinged to the lid, an ejector slide and if necessary a spoon connected therewith for ejecting a tobacco skein pressed in the tobacco press chamber out of said chamber, via an opening provided in the casing into a (filter) cigarette tube, of a clamp device , which holds the (filter) cigarette tube in a clamping manner on a socket located at the outlet of the tobacco press chamber, and of are silently-engaging, snap-in or the like device for detachable connection of casing and lid.
Such a hand filling device for cigarette tubes, particularly for filter cigarette tubes, with a tobacco press chamber extending in the longitudinal direction of the same, is known from DE-PS 2021738. The tobacco press chamber of this hand filling device is substantially formed by a casing located in the base portion, and a press head, which is provided on a lid covering the casing and hinged to the casing. Furthermore, the tobacco press chamber of this hand filling device is delimited by a spoon and by an ejector slide for ejecting a pressed tobacco skein out of the tobacco press chamber via an opening provided in the casing into a (filter) cigarette tube. This hand filling device also has a clamp device, which holds the (filter) cigarette tube in a clamping manner on a socket located at the outlet of the tobacco press chamber. Finally, this hand filling device also has a resiliently-engaging, snap-in or the like device for detachable connection of casing and lid, which has a substantially hook-shaped resiliently engaging nose connected to the free end of the lid opposite the hinge points between lid and casing, and located on a resilient elastic web, said nose being engageable with a resilient projection provided on the casing. Thus the resiliently engaging nose extends roughly in the direction of the hinge point between the lid and casing and the resiliently engaging projection roughly in the opposite direction thereto.
The similarly functioning hand filling device is also known from DE-4207196 A 1, this hand filling device involving a further development of the aforementioned device according to DE-PS 20 21 738. The further development relates to the already mentioned resiliently-engaging or snap-in device for detachable connection of casing and lid and to a particularly lightweight and yet stable construction of the device as a whole.
The object underlying the invention is to make available a hand filling device of the type named, the tobacco press chamber of which is adaptable to various lengths of prefabricated (filter) cigarette tubes, i.e. in particular to “king size” tubes on the one hand and “regular size” tubes on the other hand.
This object is achieved according to the invention by the characterising features of claim
1
, constructive details of preferred embodiments being described in the sub-claims.
Thus the core of the present invention resides in the fact that measures are taken which permit adaptation of the filling length of the tobacco press chamber to the length of the tobacco receiving space of a prefabricated cigarette paper tube, particularly filter cigarette paper tube, to be filled, without the function of the hand filling device requiring to be otherwise altered. It is merely necessary to dispose a stop means in an off-settable fashion, by means of positioning of which the desired filling length of the tobacco press chamber may be determined.
In that the ejector slide is connected with a spoon, its length must be so selected that even at the minimum filling length of the tobacco press chamber it is still located within the same, i.e. does not project outwards through the opening provided in the casing. According to the invention, at least two different filling lengths of the tobacco press chamber may be adjusted, i.e. one for filling a “king size” tube and the other a “regular size” tube. Other adjustments however may be envisaged, insofar as corresponding tubes are available. By the filling length of the tobacco press chamber is meant the maximum length of the same when the ejector slide is fully retracted. In this position, the tobacco press chamber is filled with tobacco.
The present invention can also naturally be used for hand filling devices, e.g. for hand filling devices with a pivoting lever for actuating the ejector slide, wherein a rack passed about a gear wheel can be provided between the pivot lever and the ejector slide. In this case the stop means provided according to the invention may either be associated directly with the ejector slide or with the pivot lever, in such a way that the maximum retracted position of the ejector slide can be altered.
Accordingly, the filling length of the tobacco press chamber of course also changes.
Furthermore, it is irrelevant whether for purposes of filling the cigarette paper tube, the ejector slide is moved relative to the casing or the casing relative to the ejector slide. In both cases the tobacco filling position of the ejector slide is set by a stop means which may be either off-set on the casing relative to the ejector slide, or on the ejector slide relative to the casing.
