oo oo • • oo oo ù. …. Range of the invention: The invention concerns a device for the production of food products and in particular a device for the production of food products with two layers, whereby an exterior material an internal material xu-ùmantelt. Background of the invention: While stationary the technology are well well-known devices, which for the production of food products with two layers, as for example “Chinese is intended bun”. For example with these food products internal food (“filling”) is covered up for example a bean paste, by outside food, (” telung',) a paste. Such a device is revealed in the Japanese utility model writing No. 4-43032 of the applicant. This device covers a promoter for the supply of a filling, a promoter for the supply of the shroud, a pair of double screwing promoters, a pair vane-type pumps and a double nozzle. The screwing promoters work separately, whereby everyone takes up the appropriate filling and/or shroud of the appropriate promoter and transported to the appropriate vane-type pump. The vane-type pumps measure the transported material and feed the double nozzle for the extrusion of an oblong and covered up food product, as the outside material promoter coats the internal material of the other promoter. Each screwing promoter covers a rotatable screw or spiral, which extends underneath the appropriate promoter to an opening of the double nozzle, so that the inside and the outside food are transported by the " rotation of the screws from the promoters to the double nozzle. Usually the oblong product becomes, that by the double nozzle • ö: : “““. : : : oo •: …. oo gg ooo oo gg 2 spent to a gumption device is supplied, which cuts continuously the oblong product, in order to produce for example a rounded or easily rounded covered up product, with which a coat the filling surrounds in each case. The rounded and covered up products, which are spent by the gumption device, are delivered then on a linear promoter, for example on a belt conveyor. The accumulation at rounded and covered up products can be increased, as two or more double nozzles and appropriate gumption devices, as well as appropriate pairs of screwing promoters are used, as this is revealed in the Japanese patent publication No. 10 ' 99025 A of the applicant. The arrangement of the manufacture line is like that each screwing promoter for the filling or the shroud is arranged in an oblong housing, which is so aligned that the rotary shank of the screw runs right-angled for the promotion direction of the linear promoter. For example two if numbers of the rounded covered up products are to be delivered in parallel arrangement at the same time on the linear promoter, then over the linear promoter two double nozzles, two double vane-type pumps and two double gumption devices on each side of the linear promoter are arranged. Two pairs of oblong housings with in each case a screwing promoter are likewise necessary. Around this to reach some examples were suggested by remarks of the linear promoter and the two pairs of the oblong housings. During an execution the linear promoter and the two pairs of the oblong housings are cross-shaped arranged, whereby a pair of the oblong housings on the right side and the opposite pair of the oblong housings on the left side desiinearen FSrderersü rdnet is ßei this arrangement exist grNa teiI i. that on each side of the linear promoter much area is necessary, there the oblong housings for education of the: … o: : …. EO OS oQe • oo æo 3 cross before-rise up. Besides the food must be supplied from both sides the linear promoter to the screwing promoters and thus is necessary different supply routes, which can be very much complicated. During an alternative execution everyone of the oblong housings accepts a screwing promoter and the housings is parallel on a side of the linear promoter arranged. During this execution the area can be reduced on the other side of the linear promoter. Besides the supply routes and the associated means can be more simply trained. Since however ùdie two double nozzles are parallel arranged over the linear promoter, the distance, over which the food materials are transported, between in each case differentiates between itself one on the right and one on the left a pair of the screwing promoters and the double nozzle as well as the other pair of the screwing promoters and the appropriate double nozzle. Due to this difference the quantities of the oblong products, which are delivered by the double nozzles, can be unequal. ù. - '…: . -. --. -. --. • o G • • • Q • oo oo • • • oo oo 4 during the arrangement of the rotary shank of the screw of each screwing promoter and the rotary shank of the appropriate vane-type pump can be these rotary shanks transferred undin parallel arrangement to different levels arranged. Unfavorable it is here that the height of equipment, which exhibits such upper and lower transfers of the shanks must be increased. An alternative solution to the problem mentioned consists of the fact that the rotary shank of the screw of the screwing promoter and the rotary shank of the appropriate vane-type pump are connected with a curved pipe and arranged on the same level. Although with this alternative execution the height of the equipment can be decreased, then in contrast to this the direction of the river of the food from each screw must be turned back to the appropriate vane-type pump with the curved pipe. Such a detour can cause the unwanted kneading of the food due to frictions • at internal walls. Regarding the components and the construction of usual devices the Anzah corresponds! the vane-type pump one to one of the number • of screwing promoters. If a majority is thus used by double nozzles, then becomes an appropriate number of. Vane-type pumps and thus the appropriate number of screwing promoters uses. The entire construction of the devices becomes accordingly more complicated. In order to simplify the construction of the devices, one suggested, using a double screwing promoter who exhibits a pair of screws or spirals and who can be used in place of a pair screwing promoters. During this construction the disadvantage exists however likewise that unwanted kneading takes place. ù… .......... -. -. •. : -. _. •… • • • • ö • o • • oo • e • • oo ol • • • oo oo while stationary the technology exists thus a need according to a compact and simple device, with which doppelschichtige food products without unwanted kneading in series can be manufactured. With the conventional devices a further problem, which results regarding the vane-type pumps, exists kind descriptive that above. Each vane-type pump covers a radial arrangement of wings, which are arranged around the rotary shank of the vane-type pump at different points of the extent, so that each area, which is formed by two neighbouring wings, takes up a quantity of the food.

The available invention creates a device for manufacturing covered up food products, with which an exterior food surrounds internal food. The device covers a linear promoter, who possesses certain width and length and for it serves, the covered up food products, which are delivered on the linear promoter, to transport in several over the width of the linear promoter distributed rows in promotion direction, i.e. along the length of the linear promoter. The device enclosure besides several units, which are arranged over the linear promoter and who serves in each case for it, covered up food products to produce, which correspond to a row each several numbers of the covered up food products on the linear promoter. Several units are parallel to each other arranged, so that their lengths in the promotion direction of the linear promoter extend. le oo “: "": "" i • o • • • - • e ° ' • oo oo • • • • oo o each unit several units covers 1) a first conveyance with a discharge opening for the admission” ...... the internal food and for the delivery of this internal food discharge opening. 2) a second conveyance with a discharge opening for the admission and delivery of the outside food, whereby the second conveyance is arranged opposite the first Fördezmittel, 3) a pair vane-type pumps, of which one for the internal food and the other one for the outside food are intended, whereby each Flügeipumpe an inlet into the proximity of the corresponding discharge opening of the corresponding conveyance and a opposite discharge opening aufweist1, and whereby each vane-type pump takes up appropriate food of the corresponding discharge opening of the corresponding conveyance at the inlet of the vane-type pump and continuously in pre-determined quantities by the opposite discharge opening of the vane-type pump discharges the taken up food, 4) shroud means, those between the g .eg lying outer one l ssend nügel “, internal food the one • Vane-type pump with the outside food of the other vane-type pump to cover up, so that an oblong product is formed, with which the outside food the internal food surrounds, whereby the shroud means deliver besides the oblong product, 5) Schneidmittel, which are arranged below the shroud means and serve for it, the oblong product to cut, so that a majority is formed by covered up food products, whereby with each product the outside food surrounds the internal food and the cut products on the linear promoter is put down, so that the put down and cut products form a pre-determined row for several numbers of the covered up food products on the linear promoter. Preferably two or more units form an integrated unit. In a preferential execution each conveyance points a rotary screw or spiral OF, in order to promote the appropriate food to the discharge opening of the conveyance. The rotary shank of the rotary screw can extend horizontal. In this case the rotary screw and the pump on the same level can be arranged. Alternatively æ o can: o: • ° oo oo • oo oa 7 the rotary arranged its. Shank of the rotary screw vertically in a preferential execution possesses each vane-type pump a vertical rotary shank.

Short description of the designs: Remark examples, characteristics and advantages of the available invention are more near described in the following on the basis the design.

Specification of the preferential execution forms: In the design are resemble or similar components with same numbers designation. The figures i, 2 and 3 point a preferential execution of a device 1 to continuous manufacturing of the two-layered products of the invention. Before the gumption process begins, the doppelschichtige product is an essentially oblong or bar-shaped product, which exhibits a cross sectional area, which is either essentially rectangular or essentially in a circle or semicircular. This product consists of two layers: : i “°” • oo • 6 o • oo industrial union ooo EEC NO an outside material (here called “shroud”) and internal food (here called “filling”), which of the shroud is enclosed. The final product produced by the device 1 is made by the cutting process of the oblong product. In addition, the final product is essentially rounded or easily rounded and doppellagig, can exhibit different other forms, for example the form of a Knödels, or be also a product which is based on rice. With the available invention the shroud is a food product, as for example a paste, a wheat paste, based on rice, cheese, meat, a sea product or any paste goods product or such a thing, while the filling likewise food, for example a bean paste, jam, cheese, meat, in-finished MeeresprOdükt irgendeinePästeoderldergieichen or • is. It understands itself that in the description the term “final product” is not always a final product which is available for the consumer, but also any covered up food product to be can, an essentially rounded, semicircular form or such a thing exhibit can. For the specialist it is clear that a cook procedure, for example warming up or:: :! ii: EO ton • • NO 9 treating with steam or another procedure on the manufactured product in the device 1 to be expenditure-practiced can. The device 1 shown in figure 1 covers a rack 3, which exhibits a Einfülltrichter 7 for the supply of the filling 5 and a Einfülltrichter ii for the supply of the shroud 9 within the upper range. Like in particular pointed to figure 2, the device 1 covers an integrated unit, which exhibits two units for the production ùdes of final product 23 in several rows, for example in two rows, those on a suitable linear promoter, for example on a belt conveyor 25 to be delivered. Underneath the first Einfülltrichters 7 a promoter is arranged, who takes up the filling and these a pair. Double nozzles 13A and 13B of the rack 3 supplies. Similarly a promoter 17 is arranged under the Einfülltrichter II, who takes up the shroud and to a pair double nozzles 13A and 13B promotes. The promoter 15 and the promoter 17 are symmetrical-arranged concerning a vertical axle center (not shown) of the device 1. In order to accomplish the production in two rows, the double glands 13A and 13B are arranged in two rows between the promoters and 17, in order to extrude and in the form oblong product connect the filling of the promoters 15 and the shroud of the promoter 17 downward, with which the shroud surrounds the filling. In order to accomplish the production in two rows, are besides two vertically movable gumption devices 21 (of those in figure 1 only one is shown) in the rack 3 likewise in two rows intended, so that each gumption device 21 underneath a double nozzle 13A or 13B is arranged. Each gumption device 21 receives and cuts the oblong product, which is extruded by the appropriate double nozzles 13A or 13B, so that rounded and covered up products develop. The gumption devices 21 are while stationary to the technology actually well-known and for example in US 5.882.711 of the applicant revealed. There is here in addition, other gumption devices conceivably. • IO ° ° • • • oö °°gö °°°ö e°° • •, J • oo o0 ooo oo gg in the rack 3 is arranged the belt conveyor 25 below the gumption devices 21 and receives the covered up products 25 around it a further station to supply. Although belt conveyor admits 25 while stationary of the technology well is, this is not limited to the execution shown the figures. On the basis the figure 2 the promoter 15 for the filling and the promoter 17 for the shroud are described in the following. Since the two promoters 15 and 17 are trained equal, the following description and the function of the promoter 15 transferable for the filling also to the promoter 17 for the shroud are. The promoter 15 for the filling covers a double screwing promoter 27 for the admission of the filling, which is supplied by the Einfülltrichter 7. The promoter 15 points besides a pair vane-type pumps 29a and 29b up, which form a measuring pump in each case, in order to promote continuously a certain quantity of the filling of the screwing promoter 27 to the appropriate double nozzle 13A and 13B. In order to manufacture in two rows, the vane-type pumps 29a and 29b are likewise arranged in two rows. The double screwing promoters 27 cover a screwing housing 31, whose internal floor part recesses form a pair, those a semicircular cross section exhibit in each case and a pair horizontal extending screws 33A and 33B are stored in the housing 31 in these recesses. The recesses and the horizontal screws 33A and 33B are oblong trained and essentially parallel to the promotion direction of the linear promoter the screws 33A and 33B possess spiral turns 35A and 35B, which peeled themselves around the horizontal rotary 36A and/or 36B wind. The spiral turn 35A and the turn 35B possess opposite screwing directions. The two screws 33A and 33B can be synchronized in such a way that they rotate in opposite directions.

Alternatively they can be together arranged also opposite phases and close. In order to rotate the screws 33A and 33B synchronously in opposite directions, can the rotary shanks 36A and 36B with the proximal ends of screws 33A and 33B be connected and also from these loosened and with suitable tax engines, for example to servo actuators 37A and 37B be coupled. Alternatively a pair transmission with same radius can be able to be connected to be intended, those in the interference with one another is and on the rotary shanks is arranged and for the drive with suitable tax engines, for example for servo actuators by a suitable transmission mechanism, the one suitable driving element, a chain or a volume the etc. exhibits. .o…: ....... -…. :: ': : “2: i • oo oo • 12 in place of the two screws 33A and 33B can be used also a screw, the one comparatively large radius possesses and which the same function implements as the two screws 33A and 33B. If in figure 2 the servo actuators 37A and 37B rotate in an appropriate way the screws 33A and 33B in opposite direction, then the screws 33A and 33B promote the food to the appropriate vane-type pumps 29A and 29B. As mentions above, the phase of the spiral turns 35A and 35 Bvorzug_s knows. e. seentsprechend the denEigenschaften food to be adjusted. The vane-type pumps 29A and 29B cover vertically rotating Schelfte 43A and/or 43B as well as a series of radially extending mobile wings 49. The series of the radially extending…. iichenFiQgel 49 forms a radial arrangement of wings 49, which around aie rotary Schafte43A and/or 43B at points are, which are to each other arranged in the distance. Vane-type pumps of pair of the 29A and 29B are arranged in a pump housing 39, with the open ends of the screwing housing 31 communicate. The pump housing 39 covers conical internal walls, which define a conical passage 41, which form a becoming smaller conical area laterally and neighbouring to the screw housing 31 on opposite sides. The walls form besides a pair of recesses, which with the conical passage 41 over openings 41A and 41B at the conical internal walls communicate. These recesses take up the appropriate vane-type pumps 29A and 29B, so that the vertically rotating shanks 43A and 43B are arranged rotatable in symmetrical arrangement around the narrow side of the conical passage 41. In order to rotate the shanks 43A and 43B synchronously in opposite direction, are these with a suitable drive mechanism 45, for example a driving belt or a driving chain coupled. Both vertically rotating shanks 43A and 43B are coupled for the drive with a suitable here tax engine not shown. Alternatively can be rotated the shanks 43A and 43B individually in each case with an own tax engine. ù…: “. “: ” “',”. .i.:. “13 the vertical rotary shanks 43A and 43B is integrated in vertical rotary cylinders 47A and/or 47B, which cylinder on same level as the screws 33A and 33B is arranged in the pump housing 39. The internal walls both rotary cylinders of the 47A and 47B exhibit a majority of slots, which extend over the length of the cylinder and a majority of wing 49A and 49B take up, in such a manner that these wings are radial and horizontal movable. The pump housing 39 possesses teeth 51A and 51B with a suitable profile, in order to move the wings radially with the rotation of the cylinders 47A and 47B. From the internal wall 52 of the pump housing 39 a separation wall 53 extends into the internal range of the conical passage 41, where the internal wall 52 contacts the rotary cylinders 47A and 47B. At opposite sides of the conical passage ùdie cylinder 47A and 47B of discharge openings 54A and 54B exhibits 41, which with the double nozzles 13A and 13B communicate. This arrangement decreases the length of the passages of each vane-type pump 29 to the appropriate double nozzle 13A or 13B. If thus the cylinders 47A and 47B in the direction of the arrow A rotate, then the food is transported by the double screwing promoters 27 into the common conical passage 41 and divided in same parts at the separating wall 53. The divided quantities of the food are then induced to that the distal ends of the wings 49A and 49B to the rotary cylinders 47A and 47B. Thus each area is, that by neighbouring wings 49A and 49B formed within the rotary cylinders 47A or 47B with the half quantity of the food is filled. The food in the rotary cylinders 47A and 47B are then transferred to the discharge openings 54A and 54B in same quantities and supplied to the double nozzles 13A and 13B. With the arrangement mentioned it is possible to increase the capacity of the two vane-type pumps 29A and 29B as the length of everyone is increased the cylinder 47A and/or 47B and the width of the wings 49. Since the capacity of everyone of the vane-type pumps 29 without a change in the radial dimension of the wings 49A and 49B can be changed, the length of the passage remains, in which the food in the vane-type pump is moved constantly held I J • B • • •:::: ù • 2: i ee oe • • 14 become, while the capacity of the vane-type pump can be changed. If the rotary shanks 43A and 43B of the vane-type pumps 29 rotieren1um the areas defined by the wings knows with the food supplied by the double screwing promoters 27A and 27B to directly fill, undesired kneading the food is avoided. In order to reach this, the longitudinal extending of the sections 52C and 52D, where the rotary cylinders 47A and 47B contact the internal walls 52A and 52B, should be bent between neighbouring wing 49, in order to expand the inlets 41A and 41B of the conical passage 41, and thus, where the food the wing 49 is supplied. Preferably the tax engine 37 the double promoter 27 and the tax engines of the vane-type pumps 29A and 29B are independently steered tax proceeds suitable of, for example of a computer, in order to steer their Rotätionsraten in such a way that the areas between neighbouring wings 49 within the vane-type pumps 29 with food can be led sufficiently. Thus the food of the vane-type pumps 29A and 29B continuously and in certain quantities can be promoted. With such a control the relationship of the number of rotations of the tax engine 37 of the double screwing promoter 27 to that of the tax engines of the vane-type pumps 29A and 29B can be variable steered and the rotation of each of the tax engines can be steered likewise. It is possible to fill the measuring chambers of the vane-type pumps 29 completely without exercising here in the conical Durchgang41 on the food a high pressure. The output can be adapted thus. Each double nozzle 13A (13B) covers an internal nozzle 55A (55B) for the delivery of the filling 5 and an outside nozzle 57A (57B) for the expenditure of the shroud 9, whereby the outside nozzle surrounds the internal nozzle. Passages 59 connect the internal nozzle 55A (55B) and the vane-type pump 29A (29B) for the filling and connect the outside nozzle 57A (57B) and the vane-type pump 29A (29B) for the casing. The passages 59 are trained in the radius more largely and in the length more briefly than usual passages, so that a damage can be avoided, oo • e 00 for example an undesired passage. The material with a cleaning and a maintenance knead can in simple way at the two screwing promoters 27A and 27B, which vane-type pumps 29A and 29B as well as the double nozzles 13A and 13B are accomplished, since they can be divided due to the construction described above in simple way and built up again.

The double screwing promoters for the promoter 5 for the filling and the promoter 17 for the shroud are then gently rotated and thus the filling 5 in the Einfülltrichter 7 and the shroud 9 in the Einfülltrichter ii horizontal into the appropriate vane-type pump floated. Each certain mass of the filling 5 and the shroud 9 is then moved without unwanted kneading vcmhißterenEnde 33E of the appropriate screw by the appropriate conical passage 41. The separation wall 53 within the pump housing 39 divides then the pre-determined quantity of the food 9, from the conical ù. Passage comes. The divided food then into the appropriate vane-type pump 29A and/or 29B eingebracht' which a far opening to exhibit in each case and thus the divided food quantities steered into by neighbouring wings the 49 defines areas. Since the conical passage 41 exhibits an internal diameter, which increases gradually from the inlet to the internal range and which communicates in each case further discharge openings 41A and 41B with wings 49, the food is led into it gently to the wings, thus can the vane-type pumps 29A and 29B continuously food in constant pre-determined quantities to the double nozzles 13A and 13B to transport and thus be able through benachbarte$ the wings defined areas with food to be filled sufficiently. With the double nozzles 13A and 13B points the shroud, which by the vane-type pumps 29A and 29B of the promoter 17 are extruded an oblong configuration up, whereby the filling 5, which by the vane-type pumps 29A and 29B of the promoter Q are extruded • • O W, OW4 BQO0 OQ ee • • • • • • •, • • • 00 • el IO • • • 00 EO 17, likewise an oblong configuration exhibit and by the oblong shroud 9 are surrounded.

Each gumption device 21 cuts the appropriate oblong product I around a spherical or easily rounded product 23 to form, with which the filling 5 is surrounded completely or partly by the shroud 9. The cut products (final products) 23 fall on the linear promoter 25 in two rows and to the following section are then promoted. As mentions already above, the screws 33A and 33B of the double screwing promoters 27A and 27B, the vane-type pumps 29A and 29B as well as the double nozzles 13A and 13B are arranged in same height. With this arrangement the uniform can be maintained lengths by each radius of each wing 49 of the vane-type pumps 29A and 29B to increase even if those width of each wing 49 are increased, in order the photograph capacities of the vane-type pumps 29A and 29B. Besides the depth of the radius of each measuring chamber of the vane-type pumps 29A and 29B a small little can be changed. Thereby it is possible which are filled measuring chambers of the vane-type pumps 29A and 29B fast with food, without here a chamber is not filled. In the execution mentioned above the screws 33A and 33B of the screw promoters 27 as the vane-type pumps 29A and 29B are horizontal arranged on the same height. Alternatively the device according to invention can be used also with vertical screws in accordance with figure 4. The alternative unit of the device according to invention shown in figure 4 uses a unit, which exhibits a vertical promoter 16 for the filling and a vertical promoter 18 for the shroud in place of the combination of the horizontal promoter 15 for the filling and the Einfülltrichter 7 for the filling and in appropriate combination the horizontal promoter 17 for the shroud and the Einfülltrichter ii for the shroud of the first execution ö • • • • • • • ö • • • oo • • • oo • oo oo ooo • oo oo 18 in accordance with the figures 1 to 3.

The vertical promoters 16 and 18 are in such a way arranged that their discharge openings are arranged neighbouring to the passage 41 (pointed to Fiqur4nicht) of the first execution. The rotations of the vertical screws 34 of the vertical promoter 16 for the filling and the promoter 18 for the shroud t b the food gently downward into the FlUgellmm mm of 30. ........ The “ùFüllung and the shroud are then pumped by the vane-type pumps to an appropriate double nozzle 14, which is just as trained as the double nozzles 13A and 13B of the first execution! and afterwards these are processed by the gumption device and the linear promoter (both not pointed to figure 4) equal as with the first remark example. Although the figure 4 from groups of representations points only a unit to extruding a doppelschichtigen oblong product, then it understands itself that two or more units can be arranged parallel next to each other, whereby their are arranged width crosswise to the promotion direction of the linear promoter next to each other. For the specialist it is to be left clearly that from the mentioned remarks numerous modifications and variations are possible, without the range of the available invention in accordance with the following requirements. For example the rotation axles of the vane-type pumps are represented with the remarks specified above as vertical axles, while it is obvious for the specialist that these can be bent also horizontal or. oo oo IO: “: -. -: --o oo oo ooo • oo oo 19
