"Automatic dough dividing and forming machine, for bread, rolls and the like." . '

Priority to UK patent application 26 244/65 dated June 22nd 1965 is claimed.

The invention relates to an automatic dough dividing and forming machine For bread, rolls and the like., With a dividing device that has a number of chambers or compartments to accommodate coming from a divider Has pieces of dough and that · guides and holds these pieces of dough until they be released and in their corresponding Pormnäpfe or in certain Layers fall on the molding tape, which are then covered with the Band completing mold cups match.

One of the main problems with these machines is the so-called "doubling", whereby a piece of dough does not fall off the dividing device and a following *

Piece of dough is added. In extreme cases, three or . ·: ■■ - '. even several pieces come together in the subdevice before they are released by this, which is generally also referred to as "doubling".

The present invention is based on the recognition of various factors which, individually or together, are the cause of such "duplication" problems, and the purpose of the present invention is an improved design of a subdevice to prevent duplication on the one hand and the introduction of other new features and advantages on the other on the other hand. ■■ -.- ■ -.

In a known machine, the dividing device, which has the dough pieces receives from the divider, not just sloping partitions, around the pieces of dough to lead into an enlarged space, but fall at its lower end also place these pieces of dough in a wedge-shaped space, which is formed by a closing flap and the other walls of the device with a wedge angle of 30 to 45 °. Because of the way the

, Machine the dough pieces there for essentially the whole work cycle \ 1 machine must be kept while the previous one Pieces of dough are molded and the device during the operations is rotated, the present invention is based on the knowledge that such a wedge-shaped formation at the lower end of the sub-device holds the dough under conditions which are the same as the slope of the dough the walls of the device must make it difficult to glue, if only to to delay its instantaneous fall from the sub-device sufficiently, 'and that such a momentary delay is a first The cause of the "double" is, whereby the closing flap only briefly is open and this is only enough to let the piece of dough fall and to close again to take up the next piece. The reasons

these are well known to the person skilled in the art. Knowing the cause according to, the solution to the problem is based on switching off the known "wedge-shaped" Design and in the arrangement of a chamber in which the dough piece under inertial forces during the rotation of the dividing device can move in a way which his, later

Treatment on the belt by means of the rings and cups of the machine equals *

A second feature of the sub-device, which has since been part of the known Machine has been used, consists in that the walls are lined with mushroom, for which purpose peg holes made in the metal wall serve or perforated Ks.tall have been used for the design is. This fungus is caused by moisture coming from the piece of dough saturated and its fire or liquid content is difficult control to prevent dough from sticking to it. Even though Polytetrafluoroethylene has been known for years as a coating for metal is to avoid sticking during cooking is the inventor its use for walls of a sub-device is not known. Perhaps because of the application of a porous felt-like surface for such Walls is based on a preconceived notion. Such a realization There is knowledge following a possibly undesirable factor an improved design iff. Use a suitable Basic material of a covering material, e.g. polytetrafluoroethylene, which has non-stick properties. .

A third characteristic of dividing devices that has been used since then for such machines were built, consists in »that the only closing flap in their Working method is very slow and an essential part of the process You have enough time to open it fully so that the piece of dough it is holding can fall off, and to close it again quickly needs to pick up a piece of dough newly delivered by the divider, and to wear. On the basis of this knowledge there is a thought to use a pair of narrow flaps instead of a single flap, which during the exploitable lowering movement of the dividing device very much can be opened much faster, with a relatively flat platform being provided for temporarily picking up the dough, while being within the right-angled limits proportionately fixed walls of the compartments of the sub-device can rotate freely and on them Way with the help of a non-adhesive "coating of polytetra-

fluoroethylene, as it is now used for the Formnäfe und Formringg one Molding machine is used, which prevents sticking. -

Another feature of the well-known Maechineniet, as already mentioned, the constant use of felt or similar lining for the compartments of the sub-device and following such knowledge there is a "Improved design of the walls for such compartments in it, one not adhesive coating, e.g. B. polytetrafluoroethylene, which to the satisfaction and possibly with not recognized in the moment Advantages in it is used.

A fifth feature of the present invention is the idea a suitable means for expanding the useful discharge to provide for an existing machine by means of controlled or predetermined doubling, so that ζ. B. a machine that is currently ζ. B. can produce and edit twelve pieces of dough, of which each weighs between about 21 to 84, for making and editing six pieces of dough can be moved immediately, each of which weighs between 42 to -168 g, or for four pieces of dough, of which each weighs between 63 and 252 g, or different in the case of such Large also in various forms, including z. B. the so-called Cottage loaf shape, can be combined at the same time.

A sixth characteristic of known machines is the knowledge that the currently known designs of sub-devices in their Interiors are inaccessible and means of easy 'access To clean their walls or closing flaps are missing. ', This knowledge following is the idea of an improved design, which such characteristics do not adhere »

Corresponding to the present invention is an automatic part and - molding machine with a dividing device, which with several compartments for taking and holding off a divider of the machine

original piece part are to be stranded before the pieces are delivered and are transferred to the forming belt of the machine, characterized in that that the lower end of the part;.: device by at least one closing flap is formed, which in the closed position forms a substantially horizontal receiving platform for each section. .

Another embodiment of the invention is that several and narrower closing flaps are provided, which together make a quick to be opened and closed to form platform and / or that that Closing flap is ribbed to provide a flat surface 'Avoid and associate more with lightness. A Another characteristic is that the connecting Walls of the compartments of the dividing device form a polygonal chamber for the rotating movement of the dough due to its inertia when rotating the chamber form. Another further development consists in the fact that the main walls of the subdevice are made of metal "provided with openings" and are attached in such a way that they are facing inwards and sloping downwards have inclined surfaces, the non-adhesive to receive'eines Coating, e.g. B * polytetrafluoroethylene are suitable. Furthermore, there is a development of the invention is that the subdevice from. separable or separate lower and upper parts consists »also can ■ at least one of the main walls of the upper part of the 'sub-device for Creation of access for cleaning the inner joint be stored. Furthermore, the subdevice can be used for the intended "Doubling" of pieces of dough picked up by the divider may be provided.

As shown in the drawing, the dividing head 10 of known design has six outlet openings 11, from which measured pieces of dough are ejected when the head swings downwards, to bring these outlet openings over the top of the dividing device 12! .Support at the rear end of the pivoting frame 1; 3 extending to the front. A rod 14 is detachably attached to this rail, which carries six dough-picking shaped rings 15, and four other rods 16, each of which carries six dome-shaped bowls 17. The frame 'can be rotated in a horizontal plane by eccentrics which are arranged in housings 18 on each side, in which other organs are also covered in yellow, in order to raise and lower the entire frame in known vases in relation to a conveyor belt 19, which is advanced by one step every time the frame is lifted when swung back into the rope head in order to obtain the necessary clearance. -

As can be seen more clearly from Fig. 2, the sub-device has two parts. The upper part 12 has. essentially a multiple panel of chutes on, the front and rear walls 12a, 12b of which are arranged inclined, and made of expanded metal, which is coated with poly- trafluoroethylene and arranged to be inclined inward and downward Facets are formed with which the pieces of dough come into contact * can if they fall away from the sub-organ "

several flaps 21, which are shown in a crazy lower or open position and are carried by skins; -2. Such flaps, from which are a couple below jeiar chute are also in their usual "horizontal egg closed position" dash-dotted lines shown. Maintain such old flaps and separate them Of these, however, dough-receiving devices are attached to the transport hook Porn rings 15 provided, the upper part of which is rectangular, tundis.cher Shape, while the outer part is cylindrical, and axial, inwardly v2iienäe ribs 15a with a rounded outline having. Partition walls 12c delimit the sides of the chutes. The area above the flaps 12 is rectangular. In the one shown in the drawing A ring 23 is provided for each chute. ·

In operation, the pairs of flaps 21 are narrower and lighter than that individual inclined flaps of the known type uad can therefore can be opened and calibrated faster, which means that the fully opened State is possible over a longer period of time. Because for everyone Two flaps are provided for chute, which are used for receiving the dough pieces are arranged essentially horizontally, no wedge effect is exerted on the pieces here, which are free and centered between the flaps can fall through when they are opened. the ■ clit-v en sides of the flaps are coated with polytetrafluoroethylene, to prevent urine sticking. The upper surfaces of these flaps KÖMK-n- provided with ribs eein "ur. to reduce the contact area, when the pieces of dough roll around on the surfaces of the ribs. the Pieces become, as in the known functions, during the larger one Parts, kept each cycle and because of their indolence and the Rotating movement of the deer allows them to slide on the flaps and become within the space of the Rotate lower part 20 as if held in a Pormnapf would be what movement would continue to stick the dough pieces to the Prevents flaps. The origin of the expanded metal front and back walls 12auni 13s allowed the air in that part of the housing

Experiments have shown that this upper part made of expanded metal the case-under normal conditions mostly clean for a long time holds. Also, the flaps need to be cleaned less frequently and since the housing 20 is a separate unit, this entire housing can removed from the frame as necessary without either being attached to the At the top or on the rods for the dough mounting rings 15: change.

Instead of one rod or six receiving rings, as in Fig. 3 is shown, a rod may be provided, the three larger ones Has rings 23, each of which falls in pairs and can be processed into one piece. The six bowls 1? (Fig. T) each subsequent rod are replaced by three larger bowls. This can be used if the divider for the delivery of eechs · .pieces suitable, of which each weighs between 21 and 42 g, three double-sized Pieces of 42 to 84 g can be produced.

As shown in FIGS. 4, 5 and 6, the holding or Conveyor housing with its flaps 21 chambers of essentially in On top of it is rectangular in shape, with two main transverse partition walls 20a and three removable partitions 20b are provided. Instead of of the six rings 15 of the embodiment of FIGS. 1 and 2 are here three larger rings 23 are provided, one of which is leather for the inclusion is formed by two pieces of dough from the partial organ. .-,

The lower ends of these rings have ribs 23a as shown and give a low downward horn effect. Each flap 21 has a pair of hinge sleeves 21a, which have holes 21b for receiving grub screws to attach the sockets to fasten their shafts 22. As shown in Figs iet, the upper surfaces of the flaps 21 are in such a way with

A machine with a dividing head for six pieces can be designed to produce both small and large pieces at the same time, e.g. a single piece on each side of the tape and two double pieces in between. If special loaf shapes (cottage loaf) are provided, the narrower pieces can be applied to the larger pieces by hand. Other possible changes in the size and arrangement of the dough receiving rings are within the scope of the present invention. ·

The invention is not limited to all details of the design of the Embodiment described here is limited. Rather, it must be recognized that some of the features of the new design although originally for a combination as set out above intended to represent inventive measures in their own right and are therefore to be treated as such.
