Figure 1 shows a side view of a dough processing line in a schematic representation with a head machine 28, which has a dough input 29, which for example is loaded with dough from a dough kneading machine with a tipper or by hand. Inside the topping machine 28 a dough dividing machine, not shown in detail, is arranged, which is followed by a round molding device. At 30 there is one Denotes dough output of the head machine 28, from which the divided dough pieces via a spreading belt into a quiet zone 1 arrive, which is designed as a resting fermentation cabinet in the embodiment shown here. The dough pieces are in place here in each case in dumplings, which pass through the quiet zone 1 on a hanger (not shown in detail).

The dough pieces arrive from the dough output 31 of the resting zone 1 with the help of a spreading conveyor belt 33 on a transport

band formed active band 5 · The SpreitzfÖrderband 33 consists of several narrow conveyor belts, which diverge from the rest zone 1 to the conveyor belt 5, so that their lateral distance on the conveyor belt 5 is greater than at the dough output 3o. *>

The conveyor belt 5, which is designed as a knitting belt, is followed by a position-adjustable transport device 8, which is shown in FIG lowered position is shown. By arrow 34 the direction of the change in position is shown.

Below the pivotably mounted transport device 8 ifet a periodically designed for transporting fermentation product carriers 9 working chain drive 1o arranged, its transport direction is directed to quiet zone 1. This part of the dough processing line is illustrated in FIGS. 3 and 4 explained in more detail.

The position-adjustable transport device 8 is followed by a rolling station 11, from which the dough pieces get to a take-off device 12, which is used to a certain fixed group of dough pieces Feed transport device 35, which is at right angles runs to the transport direction of the pull-off device 12. The pull-off device 12 is described in more detail with reference to FIG.

The transport device running perpendicular to the take-off device 12 35 follows another roll-out station 36 »the one Final proofer 37 follows, which is equipped with a fermentation hanger that passes through the final proofer 37 several times,

709811/0127 " ⁷ "

as indicated by the dashed lines 38 and the pulleys 39. With the aid of a further transport device, the dough pieces in their final proof are transported from the final proofer 37 to the continuous oven 41 (see FIGS. 7 "and 8)." ^F!

As can also be seen from FIG. 1, there is a height-adjustable conveyor belt 5, which is designed as an active belt counter-rotating and continuously driven knitting band 4. Only for the production of round pieces the knitting belt 4 is not required and is thus adjusted so high relative to the conveyor belt 5 that it is outside a Opportunity to act is arranged.

The knitting belt 4 is used for the production of long breads lowered a required effective height and moved in the opposite direction to the conveyor belt 5, i.e. the upper run of the belt 5 moves in the plane of the drawing from left to right and the lower run of the belt 4 in the plane of the drawing moves from right to left, so that the knitting process can take place in the space between the two strands. By changing the speed of the band 4, the effective distance can be changed. However, the belt 4 can also serve as a simple roll-out belt.

There is a transport device for the production of flatbread 8 in the lowest position according to FIG. 1. Furthermore, the conveyor belt is used for the production of flat bread 5 driven periodically. For example, there should be any delays at the dough outlet 3o of the quiet zone 1 come, for example, when a piece of dough sticks for a short time longer than the one next to it, the periodic actuation of the belt 5 thus effects an exact alignment of the rows of dough next to one another. This is an important one

709811/0127 '

Prerequisite for a right-angled take-off and this in turn for a rolling out of the dough pieces in two to each other right-angled directions. About the transport device 8, the dough pieces of the first rolling station fed and from there to take-off device 12. After passing through this take-off device, the rolled-out ones arrive Pieces of dough via the transport device 35 to the second rolling station 36, which performs a rolling process on the pieces of dough exerts, which runs at right angles to the roll-out of the roll-out station 11. After going through the first The rolling station 11, the dough pieces have an oval shape and are carried out with the aid of the rolling station 36 The oval dough piece is shaped into a circular flat dough in the vertical rolling process. After going through the last Roll-out station 36 (see FIG. 7 in this regard), the dough pieces arrive via the final proofer 37 to the conveyor oven that can be automatically loaded 41.

! The delivery of pieces of bread or long loaves to me will be the ! Transport device 8 raised, as can be seen in FIG is. The conveyor belt 5 can be driven periodically by the spreading conveyor belt 33 for the safe transfer of the dough pieces so that an exact transfer to the fermentation product carrier 9 located below the belt 5 also takes place can, which are periodically transported by the chain drive 1o. The chain drive 1o has different feed rates or step sizes can be operated with the help of adjustable rods. The transport direction of the chain drive 1o takes place in the direction of the rest zone 1. The transported by the chain drive 1o Fermentation carriers 9 are detected by a subsequent friction wheel set 24 which is driven by a motor and transported in the direction of the quiet zone 1 until this Strike against a limit switch 42, which switches on a transverse transport 26, whereby the fermentation product carrier 9 sideways

be moved out of the dough processing line.

The entire system is mechanically synchronized, i.e. all units are related to one another in terms of their work rhythm coordinated up to the transfer point to the continuous furnace 41. However, the synchronization can also be done with light barriers and / or carry out proximity switches.

The mechanical synchronization comes from the topping machine 28 which determines the rhythm of the entire system. The number of rows of dough lying next to one another is also determined by the Head machine 28 set. In the one listed in the drawings For example, six rows of dough are arranged side by side along the entire dough processing line, i.e. also in the area of the plant that is behind the at right angles guided part lies.

In an embodiment of the invention not shown in detail, however, the head machine 28 starting out, a certain number of rows of dough lying next to one another up to the right-angled bend of the dough processing section lead, while a different number of dough pieces arranged on the stretch part behind the right angle is.

In Figure 5, the trigger device 12, which is the Roll-out station 11 immediately follows, shown in an enlarged view. The task of the trigger device 12 consists in a group of dough pieces that pass through the rolling station 11 on one part of the dough processing line have to put down on a transverse transport device 35 in the same spatial assignment.

709811/0127

In the exemplary embodiment of the system shown here According to the invention, six by six rows of dough, i.e. a total of thirty-six pieces of dough, are removed from the discharge device 12 placed on the transport device 35. The dough processing lines run underneath the entire system starting from the main drive, a shaft 15 » which has an angular drive 16 on the dough processing section continued at a right angle, which has bevel gears is equipped.

From the main shaft 15 one also goes via bevel gears Pinion shaft 17, which is shown enlarged in Figure 6 and to which reference is made below. The pinion shaft carries a pinion 18 which engages with the control disk 19 stands. In the present exemplary embodiment, in which there are six rows of dough lying next to one another along the dough processing section are guided, is the ratio of the teeth of the pinion 18 to the number of teeth of the control disk equals 1: 6. If, for example, the pinion 18 has twenty teeth, the number of teeth on the control disk 19 is the same One hundred and twenty. After that, the pinion shaft 17 or the pinion 18 must rotate six times while the control disk 19 makes one revolution. With the control disc 19, a switching cam 2o is rigidly attached to a limit switch 21, which is in a fixed position, acts and which the pulling process with the help of a motor 23 (see Figure 5) triggers. This motor 23 is designed to be pole-changing and is operated with the aid of the motor from the extraction device 12 actuated limit switches 43 and 44 switched.

In Figure 5 is also the variable position transport device 8 shown in its horizontal position. By swiveling up the transport device 8, all Drive motors (23, 45) interrupted while the main shaft 15 continues to operate and thus the final fermentation tank 37 drives. This means that no more pieces of dough

709811/0127 -11-

are conveyed through the rolling station 11, while on the other hand the dough pieces in the final proofer still via the transport device 4-0 to the continuous furnace 41 are fed.

The speed of the transverse transport device is such that a seamless transfer of the dough pieces takes place with the aid of the trigger device 12.

The switching process of the trigger device 12 takes place as follows: The time at which the trigger device is actuated 12 is triggered by a piece of dough that has reached an end position on the upper belt. At this time the switching cam 2o must have reached the limit switch 21, so that in this position the motor 23 and thus the trigger device 12 is triggered. If this is not the Pail, the control disk 19 can be adjusted in a simple manner. For this purpose, reference is made to the right-hand side of FIG. 6, in which the axis 46 of the control disk 19 with its switching cam is shown in cross section. With the help of the. Hand operated Button 4-7, the axis §6 can be viewed in the Unlatch arrow 48, whereby the control disk 19 can be released from engagement with the tickle 18, so that the switching cam 2o changed in its angular position in such a way that a switching process is triggered when there is a piece of dough located on the rightmost end of the trigger device 12. At this point in time, the switching cam 2o actuate the limit switch 21. so that the motor 23 is triggered and the trigger device 12 is actuated. After this adjustment the axis 46 with the control disk 19 is moved again in the opposite direction of the arrow 48 and it a non-positive connection between the pinion and the control disk 19 is established. After making the frictional connection between the pinion 18 and the Control disk 19 is locked with the aid of the Button 47. With this adjustment, the point in time

709811/0127 _

the use of the angle deduction changed and determined, but not the ratio of rotation between the pinion and the control disk 19 · Should this ratio be changed, because instead of 6, 4 or 5, for example, adjacent Rows of dough are to be processed, it is necessary to replace the control disk 19. This exchange can be carried out relatively easily.

In Figure 5, a clutch 16 of the main shaft 15 is also shown, which can be operated by hand and the Task has to interrupt the main shaft 15 so that the dough processing section discharged at right angles with the Final proofer 37 can be switched off. At 15 there is the Shaft part denotes, which is connected to the main drive and with 49 the shaft part of the dough processing line, which to the main shaft 15 runs at right angles and with the help is strongly connected by bevel gears. The frictional connection the bevel gears are always retained, while a dog clutch 5o then engages, which can be operated by hand Lever 51 can be unlocked and triggered. The dog clutch is designed such that when engaging there is always an angular frictional connection. In In the present case, a constant engagement at 360 °, i.e. at a single angular position, is provided.

With the aid of the coupling, the topping machine in particular can be used advantageously if, for example, different types of baked goods are to be produced in one working time unit, such as flat bread or round pieces or long bread. With the aid of the coupling, the entire system can thus be acted upon intermittently. If, for example, the continuous furnace 41 that follows the final proofer 37, which can be automatically loaded, is filled, the clutch can be actuated, whereby the final proofer ψ? and the

Transport device 8 to the In the position shown in Figure 3, the production of round pieces and long loaves take place, with the loading of a others. Oven takes place by hand with the aid of the fermentation product carrier 9. In this way, the system can largely use the existing ovens can be adapted, with the most varied of baked goods by simply switching over the existing ones Dough processing units can be produced.

By pivoting the transport device 8 upwards, the chain drive 1o is exposed, as already stated above, on which there are baking trays or fermentation product carriers 9 ″, which are transported in the direction of the rest zone 1. In the figures 3 and 4 a fermentation product carrier 9 filled with additional pieces is shown, who has already left the chain drive Ίο and with the help of a transverse transport 26 at right angles from the System has been brought out · The transverse transport 26 is activated with the aid of the limit switch 42, which is activated by the fermentation material carriers is actuated, triggered.

The chain drive 1o for transporting the fermentation good carrier 9 can be different Carry out large and adjustable feeds or step sizes by actuating the appropriate, however control disks not shown in detail. With this measure it is possible to make pieces of dough of different sizes Edit sizes. For example, round pieces take up a larger area on the fermentation trays than Long loaves, so that it is necessary to adjust the step size accordingly to occupy the fermentation carriers with round pieces to change. In the production of long bread, the belts 4 and 5 run continuously, while the chain drive 1o
