    The invention relates to a device for forming a dough sheet according to the preamble of patent claim 1.
    Various devices are known from the prior art which form one or more batches of dough into a dough sheet by means of press and form rollers. Devices of this type are also known under the name of roller mills, dough band formers, etc. The devices known from the prior art are mostly used for the production of pastries and are becoming increasingly popular due to their low cost and simplicity. Due to the constant further development, such devices are also used occasionally for yeast dough or for other doughs for baked goods. Disadvantages of the systems known from the prior art are that the yeast dough is subjected to excessive loads and the devices are difficult to clean, particularly with sticky doughs, which means that they cannot fully or only partially meet the ever increasing hygienic requirements. The construction of these roller units usually requires bearings arranged on both sides of the rollers due to the required pressures and drive torques. Due to the drive elements on both sides, cleaning and operation is particularly difficult and unfavorable, so that the applicable hygiene regulations can only be met with great effort.
    It is therefore an object of the present invention to provide a device of the type mentioned at the outset, which enables easy cleaning of the device and can process a wide range of doughs.

    Further advantages and refinements of the invention result from the description and the accompanying drawings.
    The invention is shown schematically in the following with reference to particularly advantageous, but not restrictive, exemplary embodiments in the drawings and is described by way of example with reference to the drawings:
    1 shows an isometric view of a preferred embodiment of the device according to the invention, FIG. 2 shows a sectional view of a device according to the invention with a filling funnel, FIG. 3 shows an embodiment of the device according to FIG. 2 with the filling funnel opened, in FIGS. 4 to 7 an advantageous embodiment of the invention shown in different functional states, Fig. 8 shows a sectional view of an embodiment of the form roller according to the invention, Fig. 9 shows a plan view of a device according to the invention with three clamping cylinders, Fig. 10 shows a preferred embodiment of the rollers with cover plates and clamping cylinders in one Exploded view, FIG. 11 shows an alternative embodiment with a clamping cylinder and three clamping axes, FIG. 12 shows an alternative embodiment of a clamping cylinder for pressing on the cover plates, and FIG. 13 shows an embodiment of a pivotable scraper.
    1 shows a device 10 according to the invention in an isometric view. The device 10 comprises a feed roller 1, a shaping roller 2 and a discharge roller 3. The feed roller 1, the shaping roller 2 and the discharge roller 3 are each rotatably mounted about their axis. The device 10 further comprises a drive with which the feed roller 1, the shaping roller 2 and the discharge roller 3 are driven. The device 10 comprises two cover plates 7, which are each arranged laterally on the end faces of the rollers and bear against them. The device 10 further comprises a first scraper 11, which bears against the circumference of the shaping roller 2 and a second scraper 2, which bears against the circumference of the discharge roller 3. The first stripper 11 and the second stripper 12 have the same width as the rollers, that is to say the feed roller 1, the shaping roller 2 and the discharge roller 3. The feed roller 1, the forming roller 2 and the discharge roller 3 are each in a / 25th
    Bearing housing 8 overhung. The bearings or bearing points of the individual rollers, that is to say the bearing points of a floating bearing or the fixed or floating bearings of the bearing of the rollers, are arranged on one side of the device 10 within the bearing housing 8.
    2 shows a sectional view of an embodiment of the device 10 according to the invention. The device 10 has a dough feed device 4, which is designed as a dough hopper, with which dough is introduced into the device 10. The axis of the feed roller 1 is arranged at a distance from the axis of the shaping roller 2 in the area of the dough feed device 4. Due to the distance between the axes of the feed roller 1 and the shaping roller 2, there is a gap between the rollers, through which the dough is applied by the dough supply device 4 to the circumference of the feed roller 1 and the shaping roller 2. The axes of the feed roller 1, the shaping roller 2 and the discharge roller 3 are each arranged parallel to one another at a distance, so that a dough chamber 5 is formed between the feed roller 1, the shaping roller 2 and the discharge roller 3. As shown in FIG. 2, by rotating the feed roller 1, for example clockwise, and rotating the shaping roller 2 counter to the direction of rotation of the feed roller 1, i.e. counterclockwise, dough is introduced from the dough feed device 4 into the dough chamber 5. The axes of the shaping roller 2 and the discharge roller 3 are arranged at a distance from one another, so that a gap is formed between the shaping roller 2 and the discharge roller 3 or a gap is formed on the periphery between the two rollers. No distance or only a small distance is formed between the circumference of the feed roller 1 and the discharge roller 3, so that dough from the dough chamber 5 cannot emerge from the dough chamber 5 between the feed roller 1 and the discharge roller 3. By rotating the discharge roller 3 in the same direction of rotation as the feed roller 1, the dough is now discharged from the dough chamber 5 between the shaping roller 2 and the discharge roller 3 from the device 10. When the dough is discharged from the dough chamber 5, a dough sheet with a predetermined thickness is produced. The thickness of the dough sheet 2 can be specified or adjusted by adjusting the distance between the shaping roller 2 and the discharge roller 3. The device 10 also has a first scraper 11, which bears against the circumference of the shaping roller 2 in the region of the outlet of the dough chamber 5. The first stripper 11 enables the molded dough sheet to be completely detached from the shaping roller 2 and at the same time smoothes the surface of the dough sheet formed between the shaping roller 2 and the discharge roller 3. The device 10 also has a second scraper 12, which bears against the circumference of the discharge roller 3 and peels off the shaped dough sheet from the discharge roller 3/25 or prevents dough remnants of the shaped dough sheet from adhering to the discharge roller 3. In this embodiment, the discharge roller 3 is followed by a conveyor 6, in this case a conveyor belt, on which the shaped dough belt is placed and discharged from the device 10 along the transport direction shown by the arrow in FIG. 2.
    3 shows the device 10 according to the invention according to FIG. 2 in a further functional state. To simplify cleaning of the device 10, the dough supply device 4, which is designed as a dough funnel, can be pivoted about a pivot axis 42 and thus access to the dough chamber 5 or to the feed roller 1 and the shaping roller 2 can be facilitated.
    4 shows a further embodiment of the device 10 according to the invention in a perspective view. The bearings of the feed roller 1, the forming roller and the discharge roller 3 are arranged in a bearing housing 8. The bearing housing 8 is hermetically sealed, which prevents dough or cleaning agents from penetrating into the bearing housing 8 and damaging the bearings of the shaping roller 1, the discharge roller or the feed roller 1. The device 10 comprises a swivel device 9, on which the forming roll 2 is pivotably mounted. The pivoting device 9 comprises a pivoting lever 91 which has two flanges which are arranged at a distance from one another and which can be pivoted together about a pivot axis 92. The swivel device 9 further comprises a pneumatic cylinder 93 which is arranged on the end of the swivel lever 91 opposite the swivel axis 92. By changing the stroke of the piston of the pneumatic cylinder 93, the pivot lever 91 is pivoted about the pivot axis 92. The shaping roller 2 is arranged on the pivot lever 91, the mounting of the shaping roller 2 being integrated in the pivot lever 91. By pivoting the pivot lever 91 about the pivot axis 92, the shaping roller 2 is thus pivoted with it and the distance between the axis of the shaping roller 2 and the axis of the feed roller 1 or the axis of the discharge roller 3 is changed. The first stripper 11 is also arranged on the pivot lever 91, so that when the pivot lever 91 is pivoted about the pivot axis 92, the stripper 11 is also pivoted with the shaping roller 2. By changing the distance of the shaping roller 2 from the other rollers or the discharge roller 3, the distance between the circumference of the discharge roller 3 and the shaping roller 2 is changed and thus the thickness of the dough sheet that is discharged from the dough chamber 5 is adjusted or changed , Furthermore, by actuating the pneumatic cylinder 93, it is possible to pivot the swivel lever into a position in which the / 25
    Forming roller 2 has a maximum distance from the other rollers, that is to say the feed roller 1 and the discharge roller 3, and access to the dough chamber 5 is simplified (FIG. 5). As shown in Fig. 4, the shields 7 can be hung on the shafts or axes of the rollers, whereby after pivoting the pivot lever 91 and thus the pivoting of the shaping roller 2 and the sliding of the axis or shaft of the shaping roller 2 from one in the Cover plate 7 trained guide 26 can then be lifted from the axes or shafts of the discharge roller 3 and the feed roller 1. By removing the cover plates 7, access to the dough chamber 5 is further simplified or improved, and thus the cleaning and maintenance of the discharge roller 3, the forming roller 2 and the feed roller 1 are simplified (FIG. 7).
    Optionally, the first scraper 11 and / or the second scraper 12 can be arranged detachably on the device 10 or the swivel lever 91. As shown in FIGS. 2 to 7, the first scraper 11 and the second scraper 12 can be arranged on a mandrel which is arranged on the device 10 or on the swivel device 9 and can be arranged, for example, in an extendable manner thereon. By removing or pulling out the first scraper 11 and the second scraper 12, these can be cleaned separately and access to the dough chamber 5 is further simplified (FIG. 7).
    FIG. 8 shows an advantageous embodiment of the molding roll 2 or the mounting of the molding roll 2. The forming roll 2 is hollow and arranged on a bearing shaft 21. The bearing shaft 21 is itself mounted in the bearing housing 8, which is not shown, as a result of which the shaping roller 2 has a floating bearing arranged in the bearing housing 8 in addition to the dough chamber 5. The bearing shaft 21 itself is also hollow and is penetrated by a clamping axis 15. The tensioning axis 15 passes through the bearing shaft 21 completely and extends from the bearing housing 8 to through the cover plate 7 located on the opposite side of the bearing housing 8. The tensioning axis 15 has a mushroom-shaped widening 16 on the end near the cover plate 7, which is larger than the recess of the Cover plate 7 is. A clamping cylinder 13 is arranged on the end of the clamping axis 15 opposite the mushroom-shaped widening 16. By the clamping cylinder 13, the clamping axis 15 is drawn in the direction of the bearing housing 8 or in the direction of the clamping cylinder 13 and thus the cover plate 7 is pressed onto the shaping roller 2 or in the direction of the dough chamber 5, thus advantageously sealing the dough chamber 5 laterally.
    Alternatively, it is provided that, as shown in FIGS. 9 and 10, the device 10 comprises three clamping cylinders 13 and three clamping axes 15, each of which is represented by one of the / 25
    Rollers, that is, the forming roller 2, the discharge roller 3 and the feed roller 1 are carried out and the cover plate 7 presses against the rollers with a mushroom-shaped widening 16.
    As shown in FIG. 11, it can alternatively be provided that the three tensioning axes 15, which each pass through one of the rollers, i.e. the feed roller 1, the discharge roller 3 or the shaping roller 2, are also arranged on a tensioning flange 14 and the tensioning flange 14 with a clamping cylinder 13 is connected.
    12 shows an optional configuration of a part of the device 10 in an isometric illustration. In an optional embodiment, it can be provided that the cover plate 7, which is arranged on the side of the dough chamber 5 close to the bearing housing 8, also via a tensioning cylinder 13, which is connected to a tensioning flange 14, to the rollers, that is to say the feed roller 1, the form roller 2 and the discharge roller 3 is pressed. For this purpose, the clamping flange 14, as shown in FIG. 12, can comprise three pressure mandrels 17 which apply the pressure of the clamping cylinder 13 to the cover plate 7 and distribute it evenly thereon, so that the cover plate 7 is pressed evenly onto the rollers. It is thus possible for the dough chamber 5 to also be simply sealed on the side facing the bearing housing 8.
    FIG. 13 shows an optional design of the first scraper 11. Optionally, it can be provided that the first scraper 11 and / or the second scraper 12 are pivotably arranged on a pivot bearing 25. The device 10 can comprise a cylinder 19 which is connected to the first wiper 11 via a pivot lever 18. If the piston rod of the cylinder 19 is extended, that is to say the stroke is increased, the pivoting lever is pivoted in the direction shown by the arrow in FIG. 13 and the scraper 11 is pressed against the circumference of the shaping roller 2. If the cylinder 19 and thus the swivel lever 18 are adjusted against the direction shown in FIG. 13, the first scraper 11 lifts off the circumference of the forming roll 2. The pivoting of the first scraper 11 enables easier cleaning of the circumference of the shaping roller 2 and simplified or improved access to the dough chamber 5. As an alternative to the embodiment of the first pivoting lever 11 shown in FIG. 13, likewise or optionally only the second pivoting lever 12 can be in a pivotable manner analogously on the circumference of the discharge roller 3 and pivoted by a corresponding pivoting lever with a cylinder.
    / 25
    The function of the device is described below by way of example using a preferred embodiment of FIGS. 3 to 7:
    As shown in FIG. 3, in the operating state, the distance between the axes of the feed roller 1, the shaping roller 2 and the discharge roller 3 is arranged at a distance from one another such that a dough chamber 5 (FIG. 2) is formed between the rollers. The dough chamber 5 is laterally delimited by two cover plates 7, one on the end of the dough chamber 5 close to the bearing housing 8 and one on the side of the dough chamber 5 remote from the bearing housing 8. The first stripper 11 lies against the circumference of the shaping roller 2 and the second stripper 12 lies against the circumference of the discharge roller 3. The shields 7 are releasably attached to the axes or shafts of the feed roller 1, the forming roller 2 and the discharge roller 3, respectively. The shaping roller 2 can be pivoted about the pivot axis 92 by the pivot lever 91 and the distance between the shaping roller 2 and the feed roller 1 and the discharge roller 3 can thus be changed. By changing the distance of the shaping roller 2 from the other rollers, the thickness of the dough sheet produced, which is brought out of the dough chamber 5 between the shaping roller 2 and the discharge roller 3, can be adjusted to the defined thickness. The cover plates 7 have a guide 26 in which the axis or shaft of the shaping roller 2 is guided around the pivot axis 92 during the pivoting movement of the pivot lever 91. As shown in FIG. 5, the shaping roller 2 can be pivoted about the pivot axis 92 via the pivot lever 91 and the shaft or axis of the shaping roller 2 emerge from the guide 26. The size of the dough chamber 5 is increased by increasing the distance between the shaping roller 2 via the pivot lever 91 to the feed roller 1 and the discharge roller 2. In order to further simplify the cleaning of the shaping roller 2 and the discharge roller 3 or the dough chamber 5, as shown in FIG. 6, the first stripper 11 and the second stripper 12 swivel about their pivot axis and thus each lift from the circumference of the shaping roller 2 or from the circumference of the discharge roller 3, whereby access to the circumference of the rollers and access to the dough chamber 5 is further facilitated.
    Through the emergence of the shaft or axis of the forming roller 2 from the guide 26 of the cover plates 7, the cover plates 7 can also be lifted, as shown in FIG. 7, and access to the dough chamber 5 is then on the side of the dough chamber opposite the bearing housing 8 5 free. Due to the floating mounting of the feed roller 1, the shaping roller 2 and the discharge roller 3 on one side next to the dough chamber 5, it is possible to clean the dough chamber 5 and the feed roller 1, the shaping roller 2 and the discharge roller 3/25 on a so-called operating side simple to carry out and thus to enable a higher hygienic purity of the device 10. In order to further facilitate access to the dough chamber 5 and the rollers, it is possible, as shown in FIG. 7, for the first scraper 11 and the second scraper 12 to be fastened to a mandrel and pulled away from it or from the device 10 be applied.
    Optionally, it can be provided that the device 10 comprises a number of sensors which detect the state, the position or the presence of the cover plates 7, the feed roller 1, the shaping roller 2, the discharge roller 3, the first scraper 11 and / or the second Detect scraper 12 and if the position of the individual parts deviates or the individual parts of the device 10 are missing, this can inform the user or, if necessary, prevent the device 10 from stopping or starting up.
    Optionally, it can be provided that the clamping cylinders 13 each have a position and / or pressure sensor with which the state or the presence of the individual elements of the device 10 can be determined or detected.
    Alternatively, it can be provided that the pivoting lever 18 is pivoted by means of a hydraulic cylinder or pneumatic cylinder or electromechanically and / or the clamping cylinders 13 are designed as hydraulic cylinders or pneumatic cylinders or the clamping axes 15 are actuated electromechanically.
    A further optional embodiment of the device 10 according to the invention provides that the device 10 comprises three drives. The feed roller 1, the forming roller 2 and the discharge roller 3 can then be driven separately by means of the three drives. The separate drives make it possible to drive the feed roller 1, the shaping roller 2 and the discharge roller 3 at different speeds and thus achieve different dough movements in different areas of the device.
    Furthermore, the feed roller 1 and / or the shaping roller 2 and / or the discharge roller 3 can advantageously have a different profile. For example, it can be provided that the feed roller 1 and the shaping roller 2 have a profiled circumference in order to achieve good adhesion of the dough or to be able to bring about an advantageous deformation of the dough. The discharge roller 3 can also be smooth to achieve a smooth surface of the dough sheet.
