DOUGH BAND ORGAN WITH CUTTING DEVICE

Description

[0001] The present invention relates to a device for forming several strips of dough according to the preamble of claim 1.

[0002] In the prior art, dough band forming devices for shaping dough batches into dough bands are widely used. The systems known in the prior art usually consist of feeding devices, pre-portioning devices which break down the dough batch for forming, and dough band forming units.

[0003] Such a device is shown, for example, in US 2005 / 170031.

[0004] These dough band formers consist of at least two or more rollers or cylinders with the same or different diameters. The rollers can also have different surfaces or profiles. The length of the rollers usually determines the width of the dough bands to be produced. For baked goods, these dough bands are divided lengthwise and widthwise, one or more times depending on the product.

[0005] The cutting of a dough strip is mentioned, for example, in DE 10 2011 007294.

[0006] Two methods are known for longitudinal cutting, i.e., dividing the dough sheet into several strips along its width. Firstly, the edges of the dough sheet are trimmed, resulting in a significant portion of the dough being wasted. Secondly, the dough sheet is trimmed without removing the edges; this has the advantage of producing no edge waste, thus saving up to 15% of the dough to be processed.

[0007] In known devices and methods for trimming dough strips with edge trimming, the dough strip is produced in the dough strip former and, after exiting the dough strip former or at other points in the dough strip system, is cut lengthwise into one or more strips according to the desired shape. This is done using disc cutters, dies, water jets, etc. To obtain uniform dough strips, a certain edge (at least 10-15%) is trimmed off in such systems.

[0008] In known devices and methods for trimming dough without removing the edge, the dough is produced in the dough former and cut after exiting the former or at other points in the dough line system. To obtain uniform cross-sections, this cutting must be carried out in the flow direction in a so-called "calibration unit." Maintaining a consistent cross-section in the calibration unit requires complex side guides, which must either move along with the dough or be coated with a release agent to prevent them from sticking together. The disadvantage of these prior art systems is that a large edge section of dough is retained and / or an additional module or station is always required in the dough line system, significantly increasing effort, maintenance, cleaning, and costs.

[0009] The object of the invention is therefore to provide a device that enables longitudinal cuts of the dough strip which are cost-effective and easy to perform, allow high accuracy in the cutting of the dough strips and result in little or no waste of dough.

[0010] This problem is solved by the characterizing features of claim 1.

[0011] The invention is a device according to claim 1.

[0012] The device according to the invention makes it possible to perform longitudinal cuts directly in the dough band calibration unit or in the dough band former, thus eliminating the need for additional stations within the dough band system and reducing its length and the space it requires. No edge trimming, and therefore no waste, is produced, thereby increasing profit and preventing food waste. Furthermore, the dough band is guided from four sides during cutting by the cutting roller, the discharge roller, and the side covers, resulting in a uniform shape and width and thus high accuracy of the dough band strips. The oscillating pivoting motion of the pivoting lever in the dough band production process improves the dough quality of the dough band and the quality of the cuts into dough band strands.

[0013] Particularly advantageous embodiments of the device are defined in more detail by the features of the dependent claims: An improved quality of the cut is achieved by designing the discharge roller as a counter roller for the cutting roller, wherein the cutting blades of the cutting roller extend to the discharge roller, wherein the cutting blades in particular have a greater cutting depth than the formed dough strip, so that the dough strip between the discharge roller and the cutting roller does not undergo any deformation.

[0014] The thickness of the dough band can be advantageously adjusted if the device includes a pivoting device, wherein all forming rollers, which are each arranged on the same side of the dough chamber with respect to the thickness of the dough band, and / or the discharge roller are connected to the pivoting device and can be pivoted in the direction of the thickness of the dough band by means of the pivoting device, wherein the distance of the axes of the forming rollers and / or the discharge roller connected to the pivoting device to the axes of at least one, in particular all, of the other forming rollers and / or the discharge roller not connected to the pivoting device is adjustable and thus the thickness of the dough band can be changed and / or predetermined.

[0015] The distance between the rows of forming rollers and the thickness of the dough band can be advantageously adjusted if the pivoting device comprises two pivoting levers arranged parallel to each other, wherein the pivoting lever is pivotable about a pivoting axis, in particular by means of a hydraulic or pneumatic cylinder or electromechanically, and wherein the bearing of a number of the forming rollers, in particular all forming rollers, which are each arranged on a common side of the dough chamber with respect to the thickness of the dough band, and / or the discharge roller are arranged in the two pivoting levers, wherein when pivoting the pivoting lever, the distance of the axes of the forming rollers which are mounted in the pivoting lever and / or the discharge roller to the respective other forming rollers not mounted in the pivoting lever is adjustable and / or adjustable.

[0016] Advantageously, the device, in particular the swiveling device, may have a swiveling drive, in particular a hydraulic, pneumatic, electric, or electromechanical drive, wherein the swiveling drive is arranged and designed such that a number of the forming rollers, in particular all forming rollers that are arranged on the same side of the dough chamber with respect to the thickness of the dough strip, and / or the discharge roller can be driven oscillating about a zero point in the direction of the thickness of the dough strip, so that the distance between the axes of the forming rollers and / or the discharge roller that can be moved oscillatingly by the swiveling drive and the axes of at least one, in particular all, of the other forming rollers not driven by the swiveling drive and / or the axis of the discharge roller is adjusted oscillatingly by a predetermined distance in the dough production process.The oscillating motion of the individual rollers improves dough quality and produces a more homogeneous dough sheet, thereby significantly reducing the weight tolerance of the dough pieces. Furthermore, it facilitates the removal of the dough from the individual rollers.

[0017] The distance between the forming rollers can alternatively be easily changed if the swiveling device includes a length-adjustable adjusting element, in particular a hydraulic or pneumatic cylinder or electromechanical actuators. Adjustment via the adjusting element allows for a wide range of adjustment distances. The side wall or cover of the device can be opened, and the forming rollers can then be easily removed and cleaned in the open position.

[0018] In order to make it easy to change and adjust the cutting rollers, it can be provided that the cutting roller is arranged on an adjustment device, wherein the distance and / or the contact force of the cutting roller on the discharge roller can be adjusted by means of the adjustment device, wherein the adjustment device is in particular designed as a pivot arm adjustable about an axis on which the cutting roller is arranged.

[0019] The side edges of the cut dough strips are improved by having the discharge roller and / or the cutting roller have two side walls, each located in the area of ​​the end of the discharge roller and / or the cutting roller, wherein the side walls are arranged and designed in such a way as to prevent deformation and deflection of the dough strip when it is cut with the cutting roller.

[0020] To prevent the dough from sticking, the device may include a number of scrapers, each scraper bearing against the circumference of a forming roller, and dough can be lifted from the circumference of the respective forming roller by means of the scrapers, or the device may include a number of flouring devices and / or a number of spray elements, wherein the flouring devices and / or the spray elements are arranged in the device in such a way that dough cannot stick to the surfaces of the device that are in contact with the dough.

[0022] Advantageously, the device may comprise a number of drives, wherein the forming rollers and / or the discharge roller can each be driven jointly or separately, preferably at different speeds, or wherein the device comprises two drives, wherein the forming rollers, which are each arranged on the same side of the dough chamber with respect to the thickness of the dough strip, are each driven jointly by one of the two drives and are in particular connected to each other via gears.

[0023] A preferred embodiment of the device is achieved by having the forming rollers and / or the discharge roller and / or the cutting roller have different profiles, wherein in particular the forming rollers have a profiled circumference and the discharge roller and the cutting roller are smooth.

[0024] To make it easy to clean and replace the cutting roller and / or the blades, the cutting roller can be arranged to be replaceable on the device.

[0025] In order to automatically adjust the thickness of the dough band produced by the device and / or depending on the dough supply, it can be provided that the actuating element, in particular the hydraulic or pneumatic cylinder or the linear elements or the spindle drive, has a sensor with which the current length of the actuating element can be detected, wherein in particular the length of the actuating element and thus the thickness of the dough band can be adjusted by means of the sensor based on previously determined or entered weights of the dough pieces.

[0026] Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

[0027] The invention is shown schematically in the drawings below with reference to particularly advantageous, but not limiting, embodiments and is described by way of example with reference to the drawings: Fig. 1 shows a first embodiment of a device according to the invention in sectional view, Fig. 2 shows an embodiment of the device with six rollers, Fig. 3 shows a further embodiment of the device according to the invention with dough feeding device, Fig. 4 shows a rear view of the device according to Fig. 3 , Fig. 5 shows an alternative embodiment of the invention with a lower set dough band thickness, Fig. 6 shows a detailed view of the eccentric of the oscillation unit and Fig. 7 shows a side view of the device with a large set dough band thickness.

[0028] In Fig. 1 Figure 10 shows a simplified sectional view of an embodiment of the device 10 for forming several strips of dough. The device 10 comprises four rollers, each rotatable about its axes by means of a drive 21: two forming rollers 2, a discharge roller 3, and a cutting roller 6. Dough 30 is conveyed by a dough feed device 4 via a conveyor belt 41 in the direction of dough flow over the first two forming rollers 2.

[0029] The axes of the forming rollers 2 and the discharge roller 3 are arranged parallel to each other at a distance and form a dough chamber 5 between the forming rollers 2 and the discharge roller 3, in which the dough 30 is shaped and produced into a dough band. The device 10 further comprises two side covers 15, which abut the end faces of the forming rollers 2 and the discharge roller 3 and laterally delimit the dough chamber 5 and seal it against the environment. The dough 30 is drawn into the dough chamber 5 by the counter-rotation of the first two forming rollers 2, shaped between the forming rollers 2, any dough particles are homogenized, and thus a continuous, endless dough band is produced.

[0030] The device 10 comprises a cutting roller 6, which is arranged inside the dough chamber 5 at its outlet. The axis of the cutting roller 6 is arranged parallel to the axes of the forming rollers 2 and the discharge roller 3. The cutting roller 6 has a number of disc-shaped cutting blades 7, which extend from the circumference of the cutting roller 6 towards the discharge roller 3 to its circumference. The dough ribbon is discharged from the dough chamber 5 between the discharge roller and the cutting roller 6, whereby the dough ribbon is cut into a number of strips corresponding to the number of cutting blades 7. The width of the dough strips is determined by the distance between the cutting blades 7 and the distance between the cutting blades 7 located longitudinally on the cutting roller 6 near the end faces of the cutting roller 6. The thickness of the dough ribbon is determined by the Fig. 1 In the illustrated embodiment, the distance between the discharge roller 3 and the cutting roller 6 is predetermined. In this embodiment, the discharge roller 3 forms a counter roller for the cutting roller 6, against which the cutting blades 7 bear under pressure.

[0031] At the exit of the dough chamber 5, the dough strips cut by the cutting roller 6 are discharged from the device 10 by a dough discharge device 11, which is designed as a conveyor belt, and transported to the dough belt system for further processing.

[0032] In Fig. 2 Figure 1 shows a further embodiment of the device 10 according to the invention in a schematic sectional view. The device 10 comprises four forming rollers 2. The dough 30 is conveyed by gravity through the dough feed device 4 via a dough hopper to the first two forming rollers 2 and drawn between them into the dough chamber 5. Between the forming rollers 2, the dough band can be shaped and homogenized depending on the type of dough and formed into a dough band of defined thickness between the last forming roller 2, i.e., the one closest to the outlet of the dough chamber 5, and the discharge roller 3. The dough band formed in this way is then cut into strips of defined width between the discharge roller 3 and the cutting roller 6 and discharged from the device 10 by a dough removal device 11. In this embodiment, the dough band is no longer deformed between the cutting roller 6 and the discharge roller 3.

[0033] In Fig. 3 A further embodiment of the device 10 according to the invention is shown in a schematic side view. The device 10 has eight forming rollers 2, which are arranged in two rows of four forming rollers 2 each, laterally delimiting the dough chamber 5 or, with respect to the thickness of the dough band, are arranged on the same side. The forming rollers 2 abut each other with their circumferences and have the same diameters. The two rows of forming rollers 2 are arranged in a funnel shape relative to each other, such that the distance between the axes of the forming rollers 2, which are arranged at the same height in the dough chamber 5, decreases from the entrance of the dough chamber 5 to the exit. The thickness of the dough band is then predetermined between the last two forming rollers 2, which are arranged closest to the exit of the dough chamber 5.The dough strip is then guided between the circumference of the discharge roller 3 and the cutting roller 6 and cut there into a number of dough strips and discharged from the device 10 by means of a conveyor belt or a spreading device in which the dough strips are separated from each other.

[0034] To prevent the doughs 30, especially sticky doughs with a high water content, from sticking to the conveyor belts 41, transport rollers, and drums, so-called release agents can optionally be used. The release agents, flour, water, etc., can be applied, for example, by a number of flouring devices 23 and / or a number of spray elements 24. The flouring devices 23 create a film of flour on the belts and the surfaces of the dough strips, which adheres to them and separates the dough strip or the dough from the parts of the device 10. Subsequently, scrapers 16 are arranged on the last dough strip forming rollers to prevent any adhesion or to make it easier to scrape or detach the dough from them. If release flour is not desired for certain doughs, e.g., gluten-free doughs, a release film of water or oil can be applied using the spray elements 24.

[0035] As in Fig. 1 and Fig. 3 The device 10 can, as shown, comprise a number of scrapers 16, each located on the circumference of one or more of the forming rollers 2, in which Fig. 3 In the illustrated embodiment, the last two forming rollers 2 are in contact with the dough in the conveying direction. The dough is lifted by the scrapers 16, and any remaining dough is scraped off the respective rollers. The scraper 16 also facilitates the Fig. 1 , which is located on the circumference of the discharge roller 3, the detachment of the dough strips after cutting by the cutting roller 6.

[0036] As in the Fig. 1 bis 3 As shown, the current level of the dough 30 in the dough feed device 4 or the dough hopper can optionally be detected by means of a level sensor 18. If the level of the dough rises too high, the dough feed device 4 can be stopped, thus preventing a backup and / or unwanted deformation or pressure on the dough 30.

[0037] Fig. 4 shows a side view of the device 10 according to Fig. 3 with a view of the circumference of one of the rows of forming rollers 2. The forming rollers 4 are each mounted at their end faces in the side covers 15. The device 10 further comprises a drive 21 which is connected to the forming rollers 2 via gears. The forming rollers are each driven uniformly by the drive 21, with the gears between the forming rollers 2 transmitting the rotation to the next one.

[0038] The cutting roller 6 is also connected to the forming rollers 2 and the drive via a gear. The rotational speed of the forming rollers 2, the discharge roller 3, and the cutting roller 6 can be the same or optionally different. The cutting disc 6 has 5 cutting blades 7, which are disc-shaped and extend to the circumference of the discharge roller 3 ( Fig. 3 ) extend. The side covers 15 laterally delimit the dough chamber 5 and thus define the width of the dough band. In the embodiment of the Fig. 3 and 4 cut into evenly wide strips of dough, the width of which is determined by the distance between the cutting blades 7 and the side covers 15.

[0039] Fig. 5 Figure 1 shows a further embodiment of the device 10 according to the invention, with a view of the end faces of the rollers. The device 10 has eight forming rollers 2, which are arranged in two rows of four forming rollers 2 each, laterally delimiting the dough chamber 5 or arranged on the same side with respect to the thickness of the dough strip. The forming rollers 2 are spaced apart from their neighbors, so that they are spaced apart around their circumference. The forming rollers 2 have different diameters, with the diameter of the forming rollers 2 decreasing from the inlet of the dough chamber 5 to the outlet of the dough chamber 5. The two rows of forming rollers 2 are arranged in a funnel shape relative to each other, so that the distance between the axes of the forming rollers 2, which are arranged at the same height in the dough chamber 5, decreases from the inlet of the dough chamber 5 to the outlet. The device 10 has two drives 21, which are designed as motors.The two drives 21 each drive the forming rollers 2 on the respective side of the dough chamber 5 together. The discharge roller 3 is designed as a counter roller for the cutting roller 6, with the cutting blades 7 of the cutting roller 6 extending to the discharge roller 3. The cutting blades 7 have a greater cutting depth than the formed dough strip, so that the dough strip does not deform between the discharge roller 3 and the cutting roller 6.

[0040] The device 10 has a pivoting device 8 with which the four forming rollers 2, which are arranged on the same side of the dough chamber 5 with respect to the thickness of the dough band, can be pivoted or adjusted in the direction of the thickness of the dough band. The distance between the axes of the forming rollers 2 connected to the pivoting device 8 is thereby adjusted relative to the axes of all other forming rollers 2 not connected to the pivoting device 8. This allows the thickness of the dough band to be varied and predetermined.

[0041] The pivoting device 8 has two pivoting levers 81 arranged parallel to each other in the direction of the width of the dough chamber 5. The four forming rollers 2, which are arranged on the same side of the dough chamber 5 with respect to the thickness of the dough strip, are mounted on the pivoting levers 81. When the pivoting lever 8 is pivoted, the distance between the axes of the forming rollers 2 mounted in the pivoting lever 81 and the other forming rollers 2, which are not mounted in the pivoting lever 81 and are arranged together on the other side of the dough chamber, is adjustable.

[0042] The swivel device 8 further comprises a swivel drive 20, which drives an electric motor 12. An eccentric 13, with a defined eccentricity e, is connected to the electric motor 12. Fig. 6 ), which rotates when the motor 12 is operated. An actuating element, designed as a hydraulic cylinder 14, is arranged between the eccentric 13 and the pivot lever 81. The hydraulic cylinder 14 is connected at one end of its piston to the eccentric 13 and at the other end, or housing, to the pivot lever 81. When the eccentric 13 is driven by the motor 12, the pivot lever 81 is pivoted by a predefined value via the hydraulic cylinder 14 about the pivot axis 82. This oscillating pivoting motion of the pivot lever 81 in the dough strip production process improves the dough quality of the dough strip and the quality of the cuts in the dough strip into strands.

[0043] Optionally, as in the Fig. 5 and 7As shown, the adjusting device is designed to be length-adjustable. Thus, the hydraulic cylinder 14 can be retracted or extended by applying pressure, voltage, or control signals, thereby changing the distance X and thus the distance between the axes of the forming rollers 2 attached to the pivot lever 81 and the forming rollers 2 not attached to the pivot lever 81 or the pivoting device 8. Fig. 5 The device 10 is shown with a small distance X and in Fig. 7 with a large distance X. By changing the distance X, the thickness of the dough band can be changed or the device 10 can be moved into a cleaning position in which the individual rollers and the dough chamber 5 are easily accessible and can thus be easily cleaned.

[0044] Alternatively, the actuating element can be designed as a linear element, spindle drive, etc. instead of a hydraulic cylinder 14, whereby the distance between the axes of the forming rollers can be changed when adjusting the linear element, spindle drive, etc.

[0045] The cutting roller 6 is arranged on an adjusting device 25. The adjusting device 25 is designed as a pivoting arm 26 adjustable about an axis, with which the distance and / or the contact force of the cutting roller 6 against the discharge roller 3 can be adjusted.

[0046] Alternatively, the swivel drive 20 can be designed to be hydraulic, pneumatic, electric or electromechanical.

[0047] Optionally, the discharge roller 3 or the cutting roller 6 can have two side walls 31 ( Fig. 6) which are each arranged in the area of ​​one end of the discharge roller 3 and / or the cutting roller 6. The side walls 31 prevent deformation and deflection of the dough band when it is cut by the cutting roller 6 and ensure a clean cut.

[0048] Optionally, the forming rollers 2 and / or the discharge roller 3 and / or the cutting roller 6 can have different profiles, wherein in particular the forming rollers 3 have a profiled circumference and the discharge roller 3 and the cutting roller 6 are smooth.

[0049] Optionally, the actuating element, in particular the hydraulic or pneumatic cylinder 14, the linear elements, or the spindle drive, can be equipped with sensors. These sensors then detect the current length of the actuating element. Based on previously determined or entered weights of the dough pieces, the length of the actuating element, and thus the thickness of the dough band, can then be adjusted or changed using these sensors.
