The invention relates to a device for feeding cigarettes or other rod-shaped ones Objects on filter mouthpiece cigarette machines from a magazine through a channel into the grooves a continuously revolving grooved drum.

There are known devices in which the cigarette magazine and the filter rod magazine directly the grooved drum are arranged. This design results in particular in the case of comparatively high-speed ones Groove drums run the risk of making a groove either with a cigarette or with a filter rod is not filled. The cigarettes can also be in the magazine as a result of the pressure of the overlying cigarettes are partially damaged when they are inserted into the grooves of the grooved drum.

Devices are also known in which the cigarettes are placed directly below the magazine Manholes arranged next to one another fall. At the exit of these shafts, the cigarettes are first stopped by stationary stops and then by drivers provided with a cam taken and stored in the grooves of the grooved drum. To those with high peripheral speeds To feed rotating grooved drums with cigarettes, there are several with these devices Shafts with appropriate driver elements required.

Furthermore, devices are known in which cigarettes immediately after the cutting tube of rod cigarette machines be conveyed pneumatically in the axial direction in a grooved drum. At this The device is thus the filling of a fan-provided revolving grooved drum by means of Suction air carried out.

Devices are also known in which the filter plugs are grooved from one another Disc to be transferred to a grooved drum located below. After the handover, the Filter plugs one after the other by means of a compressed air stream which blows into the grooves of the grooved drum, conveyed in the axial direction to a stationary wall and thereby individually aligned.

Devices on rod cigarette machines are also known in which air jet nozzles are arranged are that the cigarettes, which are moved forward in the direction of their longitudinal axis, by a Move periodically acting air flow transversely to the conveying direction on a deposit belt sideways.

However, these devices only cause the lateral displacement of cigarettes in the direction their longitudinal axis are moved forward.

The invention is based on the object of falling from a magazine through a short chute Cigarettes continuously into the grooves with a comparatively high peripheral speed the rotating grooved drum from the chute at an increased speed.

This is achieved according to the invention in that to accelerate the free fall of the cigarettes between the end of the chute and a conveyor drum with known application of a puff of air A blower nozzle is arranged for the transverse axial displacement of cigarettes, which is used for separation the cigarettes emits a periodically controlled flow of compressed air.

The periodically controlled air flow is expediently approximately tangential to the one provided with grooves Conveyor drum directed, which the fed cigarettes after a with the same peripheral speed revolving grooved drum.

This arrangement ensures that the cigarettes are already in the accelerated free fall a direction is given through which it is then better in the subsequent circular movement on the circumference the conveyor drum can be brought.

In the drawing, an embodiment is shown in elevation, partially in section.

The cigarettes 2 are located in the magazine 1 smooth or slightly knurled rotating roller 3, the cigarettes 2 between roller 3 and side Guide 4 taken along without any mutual friction. To avoid getting the full

The weight of the cigarettes 2 located in the magazine 1 lies on the roller 3, is a relief plate in the magazine 1 5 arranged.

The oscillating movement of one in magazine 1 attached plate 6 is the so-called bridging of the cigarettes at the outlet of the magazine 1 after the roller 3 avoided. Between. Magazine wall 7 and roller 3 as well as guide 4 is a stripping roller 8 intended. This has the task of a possible jamming of the cigarettes between magazine wall 7 and Eliminate roller 3. A vertical chute 9 is arranged below the roller 3 and the guide 4. The chute can also be designed to be slightly inclined to or from the roller 3. For this Chute 9, the cigarettes 2 get into the grooves 10 of a chute 9 arranged under the chute rotating conveyor drum 11. The groove profile of the conveyor drum 11 is designed so that the groove 10 runs somewhat in the direction of rotation in order to ensure that the cigarette 2 is securely inserted into the groove 10. The details described so far are common in this or a similar form however, they are not part of the invention and are only listed here for the sake of better understanding.

In order now to determine the time it takes for the bottom cigarette 2 to fall from the chute 9 into the groove 10 of the conveyor drum 11 in addition to accelerating their free fall, there is a downward-facing one on the chute 9 on one side Blow nozzle 12 attached. Through this, a periodically controlled flow of compressed air is not generated by one Drawn pump unit blown onto the lowest cigarette 2 located in the chute 9, whereby this cigarette enters the groove 10 of the conveyor drum 11 at an accelerated rate.

From the conveyor drum 11, the cigarettes are in the usual way in a grooved drum 13, which with the the same peripheral speed runs as the conveyor drum 11, delivered. The cigarettes in the conveyor drum 11 slide along the guide 14 attached to the side. The one in the grooved drum 13 cigarettes 2 located are then given to other processing stations.

Claims (2)

Patent claims: 1. Device for feeding cigarettes or other rod-shaped objects from a magazine in continuously rotating grooved drums on filter mouthpiece cigarette machines, the cigarettes from the magazine rotating between one below the magazine Slide through the roller and a guide and conveyed on to a vertical chute are, characterized in that to accelerate the free fall the cigarettes between the end of the chute and a conveyor drum (11) known application of a puff of air for the transverse axial displacement of cigarettes a blower nozzle (12) is arranged for a periodically controlled flow of compressed air. 2. Apparatus according to claim 1, characterized in that the compressed air flow of the blower nozzle (12) approximately tangential to the grooved conveyor drum (11), which the fed Cigarettes after the grooved drum (13) rotating at the same circumferential speed is directed.
