The invention relates to an automatically operating arrangement for the production of pies or the like Baking molds, which are circulated by a conveyor through a molding device the pies in the set-wise cavities of the baking molds, through an oven and be passed through a mold separation station, in which a separation of the pies and the baking molds he follows.

There are automatic arrangements for making and baking bread are known in which on a continuously moving conveyor track consisting of clamshell foldable strips Dough is given up and shaped, whereupon the dough pieces are thrown into bowls are carried out in a separate conveyor circuit, which has a considerable length. From the The shaped dough is then dropped onto a conveyor running through the oven. These known arrangement can be used for dough pieces, but not for pies or the like their exit from the oven are extremely sensitive and careful handling need. It is also known a wafer baking machine that has two endless mold carrier systems which unite along a common straight path to form closed shapes, an oven being assigned to the straight route. At the beginning of the straight stretch the dough is poured in portions before the mold is completely closed, while at the end of the Distance in a mold separation station after opening the mold the baked goods are removed. The removal the baked goods must be done by hand here with sensitive goods.

The production of meat pies, jelly or fruit tarts has so far been done in individual forms. For this purpose, the dough is spread out into a bowl in a mold and a portion of the filling is added. After spreading out the filling, a dough lid is pressed on if necessary. The prepared ones Pies then enter an oven with the molds and are cooked through after leaving the oven Air cooled, removed from the mold and packaged. There are various manual Steps required, especially when removing the delicate patties from the To shape.

It is the object of the invention to provide an arrangement of the type mentioned, in which these difficulties are eliminated and the sensitive patties after leaving the oven automatically working arrangement for

is stored and at least one cover element for covering a baking pan and at least one with the cover element has cooperating support device for the baking molds and cooling trays, which opposite the cover element is movable in the radial direction.

The invention is illustrated below with reference to schematic drawings of an exemplary embodiment explained in more detail:

F i g. 1 represents schematically the entire automatic * ° working arrangement according to the invention;

F i g. Fig. 2 is a side view of the device for removing the pies from the baking pans and Transferring the pies to openwork support elements or cooling trays.

It is assumed that the arrangement is a machine for making meat patties. The pies are made in sets in baking molds, each of which has, for example, 25 mold recesses, which are arranged in 5 rows of 5 pieces each. The baking molds or molding boxes enter a pie forming station which comprises the automatically operating machines A, B and C. The molding boxes are transported step by step with the aid of a conveyor 1. The baking molds go through the following processes one after the other in the machine: First, a dough compartment and storage device A is provided, which has a number of dispensing heads, the number of which is equal to the number of rows of mold cavities in one Form box is, and the measured amount of dough exactly in each mold cavity of the first row and then in each further row of a molding box.

From the lower part and storage device A , the molding boxes pass through a device B in which the dough is pressed and shaped into a bowl. This device is in turn provided with a series of vertically movable press heads which are controlled in chronological order so that they act one after the other on successive rows of mold cavities which are located exactly below the heads. The control is carried out by the step-by-step or step-wise moving conveyor. From there, the molding boxes pass through a pie forming machine C which has a second sub-dividing and depositing device which is arranged so that it can pour the pie filling into the dough bowls. This depositing device is followed by a further pressing device which spreads the filling in the dough shells. This is followed by a device for placing and pressing the lid on, which also has means for placing a sheet of dough over each of the successive molding boxes as well as means for simultaneously punching the lid out of this sheet and pressing it onto the dough shells. The remaining dough-like material is lifted off the molding boxes and returned to the rolling device. From the pie molding device C , the molding boxes pass through a testing device F before they enter the oven H , which has continuously moving conveyor belts.

Means feeding and synchronizing the oven are provided to ensure that the oven is always full of molding boxes to ensure even baking of the pies. For this purpose, the test device F can comprise a storage device which can hold back an excess of molding boxes and maintain correct feeding of the furnace, even if, for. B. in the pie forming station should a delay or interruption of operation occur. When transferring the molding boxes from the pie forming station to the testing device F , the molding boxes are first divided into groups, for example six next to each other, in which form they are passed through the oven. An unloading device I is provided at the exit of the furnace, which takes care of the individual feeding of the molding boxes to the removal device. The removal device 7 is preferably in the form shown in FIG. 3 formed manner shown.

The mold separating device comprises a rotatable frame 105 which has two diametrically opposed cover members 106 or plates which are attached to the frame. Each plate has a plurality of protruding annular alignment elements 108 which, together with the plates 106, form pockets which correspond to the mold cavities of a molding box with a group of baking molds. The cover plates can cooperate with a molding box in such a way that the pockets cover the wells. When the arrangement is reversed, the plates serve to support the pies or the like, namely as soon as the molding boxes have been separated from the pies. Radially movable lifting members 109 for the molding boxes 101 are used to bring them into or out of contact with the cover plates and are rotated through 180 ° with the frame. In the lower station of the framework, the full molding boxes 101 are fed by a driving conveyor 120 , while after the rotation in the upper station the boxes are removed by a corresponding driving conveyor 121. At the same time, a wire basket 115 is brought in by a driver conveyor 122 , which is lowered onto the cover plate 106. Meanwhile, the next full molding box is located in the lower station. After the framework 105 has been rotated again, the patties come to lie in their original position on the wire basket 115 , which is guided away from the cover plate by the conveyor 123 after it has been lowered. Carrier conveyors 114, 119 ensure the transfer of the molding boxes or cooling trays.

This device comprises control means which control the arrival of the individual flasks and cooling trays.

After the removal or separating device /, the empty molding boxes go one after the other to a mold cooler L, a mold reversing machine M, which turns the molding boxes by 180 ° for a second pass through the cooler L , and from there the cooled molding boxes go back to the pie molding station at A. .

Further auxiliary devices for the molding box circle comprise either a dough sheeting machine D or a dough sheeting device E, the purpose of which is to feed the dough in sheet form to the molding device.

The endless conveyors for the cooling trays onto which the pies from the molding boxes at the separating station are transferred, are formed by endless conveyors 2. The endless circle encompasses

each other a glazing machine K, a precooler W, a cooler Q, a jelly injection machine P, a second cooler Q ¹ , a pie removal machine-R, a machine S washing the cooling dishes and a machine T that lifts and turns them, from which the empty cooling dishes are sent to the Mold release machine are returned. Other auxiliary machines for this circuit include wrapping machines U, to which the pies are fed after passing through the removal machine R.
