DETAILED DESCRIPTION

(9) FIG. 1 shows a perspective sectional side view of a dough portioning device 1. Dough portioning device 1 can comprise a metering device 2. Furthermore, dough portioning device 1 can comprise a conveyor device 3. Conveyor device 3 can be configured to transport dough in a conveying direction F. Metering device 2 can comprise a container 4. Container 4 can be configured to receive a supply 5 of dough. Metering device 2 can also comprise a separator 6 which can be configured to separate a defined quantity 7 of dough from supply 5 of dough. Furthermore, separator 6 can be configured to discharge quantity 7 of dough at a discharge end 8 (see FIG. 2) of metering device 2 in a discharge direction A. Conveyor device 3 can comprise a conveyor belt 9. As can be seen in FIG. 1, conveyor device 3 can be arranged below discharge end 8 of metering device 2.

(10) FIG. 2 shows metering device 2 without the other components of dough portioning device 1 in a view similar to that in FIG. 1. It is evident that discharge end 8 can comprise a section 10 on the upstream side. Furthermore, discharge end 8 can comprise a section 11 on the downstream side. Discharge end 8 can extend over a discharge length 12 from section 10 on the upstream side to section 11 on the downstream side. As shown in the present embodiment, discharge end 8 can be oriented to be substantially horizontal. In such a configuration, discharge direction A can be oriented substantially parallel to gravity, which can facilitate discharging quantities 7 of dough.

(11) FIG. 3 shows metering device 2 in a further sectional view, where the profile of the sectional plane is indicated in FIG. 1 by line III-III. It can now be seen that separator 6 can comprise two star rollers 13. Separator 6 can be configured to separate a defined quantity 7 of dough from supply 5 of dough and to discharge it at discharge end 8 by rotating star rollers 13 in opposite directions. In addition to the illustrations from FIG. 3A, FIG. 3B shows two deposited quantities 7 of dough and conveyor belt 9. Quantities 7 of dough were deposited on conveyor belt 9 in an overlapping manner. Furthermore, it can be seen that conveyor belt 9 can comprise a middle section 14. Furthermore, conveyor belt 9 can comprise two lateral sections 15. Lateral sections 15 can be foldable and/or bendable relative to middle section 14. In particular, lateral sections 15 can be bendable and/or foldable relative to middle section 14 in the direction towards metering device 2. Lateral sections 15 can each have a lateral edge 16. As can be seen in the detailed view in FIG. 3C, lateral edges 16 can be arranged at an edge distance 17 from discharge end 8, in particular from a lower edge of star rollers 13.

(12) FIG. 4 shows dough portioning device 1 in a side sectional view which is similar to the view from FIG. 1. However, only metering device 2 and conveyor device 3 are shown for the sake of clarity. It is evident that middle section 18 can be at a distance from discharge end 8 that can be variable along conveying direction F. Distance 18 can be measured in particular in discharge direction A. Middle section 14 can have a declivity 19 in the region below metering device 2 relative to discharge end 8. In particular, a distance 20 on the upstream side can be smaller than a distance 21 on the downstream side. Distance 20 on the upstream side can be defined in discharge direction A between middle section 14 and section 10 of discharge end 8 on the upstream side. Distance 21 on the downstream side can be defined in discharge direction A between middle section 14 and section 11 of discharge end 8 on the downstream side. It can also be seen in FIG. 4 that edge distance 17 can be substantially constant along discharge length 12. This can be supported in that lateral sections 16 of conveyor belt 9 are continuously bent and/or folded along discharge length 12 of the discharge end in the direction towards the metering device.

(13) A perspective view of conveyor device 3 is shown in FIG. 5. It can now be seen that conveyor device 3 can comprise a belt guide 23. Belt guide 23 can be configured to bend and/or fold lateral sections 15 of conveyor belt 9 relative to middle section 14 in the direction towards metering device 2. Lateral sections 15 can initially be arranged in an initial position S at an end of conveyor device 3 on the upstream side when viewed in conveying direction F. In particular, the lateral sections in initial position S can be oriented substantially parallel to and or coplanar with middle section 14. Lateral sections 15 can then be bent and/or folded up towards an end position E by engagement of belt guide 23 with an underside of conveyor belt 9, in particular an underside of lateral sections 15. Thereafter, lateral sections 15 can return to initial position S by slacking or absent engagement of belt guide 23 as well as by restoring forces of conveyor belt 9. It is preferred to have the region in which lateral sections 15 are arranged in end position E be arranged downstream of metering device 2. As a result, for example, edge distance 17 can be kept substantially constant.

(14) With reference to FIG. 1, a possible mode of operation of dough portioning device 1 described shall be roughly explained hereafter. A first release agent application device 22 can be arranged in conveying direction F still upstream of metering device 2. Release agent application device 22 can be configured to apply a release agent to conveyor belt 9. This can take place preferably in a region in which lateral sections 15 are still arranged in initial position S. This can facilitate the application of the release agent to lateral sections 15.

(15) In the region of metering device 2, the bending and/or folding of lateral sections 15 can then be started by belt guide 23. In the same region, metering device 2 can discharge a quantity 7 of dough at discharge end 8 of metering device 2 and deposit it on conveyor belt 9. As can be seen in the present embodiment, quantities 7 of dough can be deposited in an overlapping manner, in particular in such a way that each quantity 7 of dough can have an overlapping portion 7a and a covered portion 7b. A person skilled in the art recognizes that the drop heights of portions 7a, 7b from metering device 2 would differ if discharge end 8 and conveyor belt 9 were oriented in parallel. In particular, the drop height of an overlapping portion 7a onto a covered portion 7b of preceding quantity 7 of dough would then be smaller than a drop height of covered portion 7b onto conveyor belt 9.

(16) In the presently disclosed dough portioning device, the difference in the drop heights can be compensated for, namely in that middle section 14 has a declivity 19 relative to discharge end 8 of metering device 2. After depositing, the overlapping portions can be pressed by a shaping roller 24 into trough-shaped conveyor belt 9 in order to impart a defined shape upon the resulting strip of dough. A release agent can be applied to shaping roller 24 by a second release agent application device 25. Thereafter, lateral sections 15 can be folded back to the initial position by restoring forces of conveyor belt 9 and the resulting strip 26 of dough can be transferred to a roller system 27.

(17) It is particularly favorable to have the difference between distance 20 on the upstream side and distance 21 on the downstream side be set based on an expected thickness 28 of quantity 7 of dough. Particularly preferably, the difference between distance 20 on the upstream side and distance 21 on the downstream side can correspond substantially to thickness 28 of quantity 7 of dough.
