Description

GERMAN

The invention relates to a screw conveyor with guide disks, which intervene in one or more worm flights and inevitably move the Serve the conveyed material. According to the invention, such screw conveyors are mainly intended for machines be used to fill valve sacks or other sacks.

With the previously known screw conveyors, the theoretical conveying capacity is far from being achieved, especially if it is not free-flowing, e.g. B. substantially horizontally advanced filling goods Od. Like. Acts, while in the case of poorly flowing and baking products, a promotion is hardly possible.

Conveyor screws are known in which guide disks engage in the screw windings in order to Eliminate jams in the material feed within the screw threads. Sufficient for such purposes automatically revolving guide disks, which only partially fill the worm threads, so that the Idler pulley is never fully loaded and through the gaps at the time of engagement with the Screw threads partially flooded back the material to be conveyed. The inevitable promotion is thereby disturbed; In addition, by installing a guide disc in the product inlet, the loading of the Conveyor screw obstructed with material to be conveyed.

It is also known to use a guide disk in each worm gear, which, however, results in a expensive and complicated construction results.

The aim of the invention is for the special purposes already mentioned, namely for filling machines of valve paper bags or similar containers to provide a conveyor which causes a compaction of the conveyed goods in addition to an inevitable forward movement of the goods. This effect, above all a compression that cannot be achieved with the known screw conveyors with guide disks will.

The invention consists in that the guide disk lying outside the filling material inlet is supplied by a power source is driven, d. H. is force-controlled, and the guide disc when passing through the screw conveyor fills their corridors completely.

The arrangement of the guide disc outside of the product inlet becomes unhindered Loading of the screw conveyor with full loading of the same with filling material and an optimum compacted material achieved with the shortest filling times.

In order to prevent wear on the guide wheel and the screw conveyor, the guide disk is force-controlled, with the cost-effectiveness being increased at the same time and any malfunctions due to contamination in the guide disk guide being avoided. The high screw conveyor with inevitable

Compression pressure is achieved by applying full pressure to the guide disk, with the worm thread being completely filled in each case. This can be for example by guttural embodiments of the Schnek ^a 5 kenwindungen at least in the area of the guide plate easier. The guide disk can be arranged in the axial direction of the screw conveyor or at an angle, depending on the requirements.

The drawing shows an exemplary embodiment of the subject matter of the invention, namely Fig. 1 shows a longitudinal section of a screw conveyor,
Fig. 2 is a cross-section of Fig. 1,
Fig. 3 is a plan view of Figs. 1 and
Fig. 4 a further embodiment of a screw conveyor, partially in view.

1 with a screw conveyor is referred to, which conveys the material to be conveyed in the direction of the arrow. Around 90 ° to the screw axis, a guide disk consisting of curved pieces 3 is provided around an axis 2. + o seen. Of the three brought in and out Curved pieces 3 is each a worm gear or a part of the same in its conveying cross-section covered.

The guide disk 3 guided in the housing 10 is inevitably set in rotation 4-5 to avoid wear, any drive from a power source being possible; for example, this drive can be derived from the worm via gears 5, 6 and bevel gears 7, 8.
The shape of the curve pieces 3 depends on the design of the worm threads. If necessary, more than three curved pieces engaging in the worm threads can also be provided on the guide disk. It is also possible to set the axis of the master

disk 3 to be movable so that the individual curve pieces over a longer period of time fully in Are engaging. In addition, several coordinated guide disks can be arranged on a screw conveyor will. The axis 2 α of a curve piece 3 a according to Fig. 4 can also be parallel or in any Arrange angles to the screw flights 4, in a preferred embodiment in one of the screw flights corresponding inclination. The worm 1 is inserted into the worm housing 11 with a certain amount of play. Through the guide disc 3, which completely fills the worm threads 4 with its curved pieces, is achieved, that the conveyed material does not rotate with the screw 1, but is inevitably advanced, wherein one with a sealed guide of the inevitably rotated guide pulley with its one-piece or multi-part Curved pieces in the slot 10 a of the housing 10 prevents any evasion of the material and thus a very effective compression of the product is achieved. In valve bag filling machines, the guide disc is primarily placed near the outlet of the Auger. Not only for transport purposes of any kind, but also for presses, e.g. B. oil presses, the device according to the invention can be used.
