The invention relates to a device for automatic dough feed, in particular for dough pieces and knitting machines that. Process wheat dough.

In the known devices of this type, three rollers are arranged below the storage container, two of which are below each other to the side of the third roller and to this for the purpose of adjustability of the delivery gap are pivotably mounted.

This one-sided adjustment has a disadvantageous effect on doughs with different consistencies because once the dough sheet to be produced is subject to unfavorable mechanical loads and thus a frequent tearing of the active skin occurs, which has the consequence that operational disruptions to the downstream Processing machines enter by gluing the dough. On the other hand, it creates an uneven surface Dough compaction, the weight differences in the dough pieces of the dough sheet that are then divided off allow.

Furthermore, in the known devices, the necessary uniform dough sheet thickness in the dispensing gap for doughs of different consistency for a subsequent fully automatic dough dividing and Knitting machine cannot be achieved.

The object of the invention is to provide an automatic dough feed, in particular for dough dividing and molding machines to create, taking into account the continuous feeding of a sheet of dough of the same thickness the different consistency of the dough.

According to the invention this is achieved in that the outlet opening of a storage container is an in a housing arranged on both sides proportionally pivotable, from two forming the working gap Rolling group existing rolling system is subordinated, whose respectively one below the other, Rollers with different diameters joined together to form a group of rollers are rigidly mounted in two adjusting levers.

The proportional adjustment of the two roller groups to one another is carried out by means of spindles rotatably mounted threaded bushings arranged on the upper end faces of the adjusting levers.

Another advantage of the design is that the shafts of the lower rollers of each roller group in the Bear the housing and act as a fulcrum for the associated group of rollers, but also at the same time as drive shafts serve for the entire roller system.

The gaps between the rollers of each roller group, which are arranged at a distance from one another in the adjusting levers, are equipped with a spring-mounted device for automatic dough feed,
especially for dough dividing and baking machines

Scrapers filled and form a closed working gap overall.

Endless belts can also be used in place of the roller groups.

This arrangement makes it possible to produce wheat doughs with different volume properties gently to form a strip of the same cross-section and the downstream fully automatic Continuous feeding of the dough dividing and rounding machine, with the work productivity being reduced by the automatic Dough supply is increased and with regard to; o a homogeneous structure of the dough a strong Reduction in weight differences occurs.

The invention is to be explained in more detail below using an exemplary embodiment. In the Drawing shows

FIG. 2 is a schematic representation of the front view according to FIG. 1.

Flanged to the outlet opening of a storage hopper 1 is a housing 2 in which two groups of rollers 3; 4 are arranged pivotable on both sides.

Each of the roller groups 3; 4 consists of three rigidly arranged one below the other and in their center distance Rollers, with two smaller rolls assigned to each large roll and according to the end face F i g. 1 in control lever 5; 6 are stored. The waves 7; 8 of the lowest pair of rollers are used as a pivot point for the roller groups in which they the Connection between the adjusting levers 5; 6 and the housing 2. At the same time, they serve as drive shafts for the entire roller system, which makes the rotary movement, matched to the performance of the

Claims (4)

downstream dough dividing 'and knitting machine obtained by a non-illustrated, stepless drive. In order to be able to form a closed working gap for the dough 9 to be compacted, the spaces between the individual rollers are provided with spring-mounted scrapers. The scrapers ll at the dough sheet outlet are only required to clean the rollers. The frontally arranged adjusting levers 5; 6 have rotatably mounted threaded sockets 12; 13, in which the spindle 14, provided with right-hand and left-hand threads, is stored. According to FIG. 2, a handwheel 15 and a chain wheel 16 are mounted on the spindle 14. The rotary movement is proportionally transmitted to the spindle 14 'and a chain wheel 16' by means of a chain hoist 17, so that a tilting of the illustrated roller group 3, which is in the control levers 5; 5 'provided with the threaded sockets 12; 12 'stores, is avoided. The device for the automatic dough feeder can be placed hanging or on a mobile frame. The mode of operation is as follows: The dough 9, which can get into the storage hopper 1 by a wide variety of conveying means, is fed by the roller pairs of the roller groups 3; 4 and gently compacted to form a dough sheet with a constant cross-section. Enlarging or reducing the inlet cross-section enables doughs of different consistencies to be processed without impairing the functionality of the downstream dough dividing and molding machine. In the case of loose, voluminous dough, turning the handwheel 15 via the spindles 14; 14 'the control levers 5; 6 and thus the roller groups 3; 4 given an angled position to each other, so that the dough gets its denser structure through constant pressure increase. Firm doughs, on the other hand, are compacted only once in their structure, i. This means that the working gap of the roller pairs of the inlet cross-section and the outlet cross-section must be of the same size. Therefore, if the roller position matches the texture of the dough, neither a very firm dough nor a dough with large air pockets can result. Patent claims: 1. Device for automatic dough feeding, especially for dough dividing and molding machines, the continuous feeding of the dough strand of the same thickness, taking into account ίο allows the different consistency of the dough, characterized in that the outlet opening of a storage container (1) is arranged in a housing (2) on both sides proportionally pivotable, consisting of two groups of rollers (3; 4) forming the working gap, whose respectively one below the other , rolls of different diameters joined together to form a group of rolls are rigidly mounted on the front side in two adjusting levers (5; 6) each. 2. Device according to claim 1, characterized in that the proportional adjustment of the two roller groups (3; 4) to one another by means of spindles (14; 14 ') via rotatably mounted threaded bushings (12 ) arranged on the upper end faces of the adjusting levers (5; 6) ; 13) takes place. 3. Apparatus according to claim 1 and 2, characterized in that the shafts 7; 8) the lower rollers of each roller group in the housing (2) store and serve as a rotation axis for the associated roller group (3; 4) and at the same time as drive shafts for the entire roller system. 4. Apparatus according to claim 1 to 3, characterized in that the spaces between the spaced apart in the adjusting levers (5; 6) arranged rollers each, roller group (3; 4) are filled with resilient scrapers (10) and a total of one form closed working gap.
