    The invention relates to a device for cutting subbands with a defined specifiable width of a dough strip according to the preamble of patent claim 1.
    In the prior art dough bands are set at Teigbandanlagen means of sizing or other rollers to a predetermined dough thickness. Particular attention is paid to ensuring that the sizing rolls or other rolls are equidistant from one another to achieve a homogeneous dough sheet thickness. Furthermore, in the prior art in longitudinal cutting units in Teigbandanlagen the cutting width of sections or subbands of a dough band defined set. It is the cutting width of the longitudinal cutting unit adjusted so that always the same width strands are cut without going into weight differences of the individual subbands.
    However, since the weight of the individual finished biscuits for consumer protection must contain at least the weight that is specified and the indication of dough pieces and dough strands in weight and not in pieces, a bakery is obliged to carry pastries with the specified weight or weight , The average of the biscuits is therefore designed to counteract manufacturing tolerance with more weight than stated. This means a disadvantage of manufacturing efficiency and increases raw material costs. The more accurately machines can produce dough pieces of the same weight, the less raw material loss is created for the bakery.
    In the known Teigbandanlagen the weight of already cut pieces of dough is recorded by weighing units and sorted underweight dough pieces, since underweight dough pieces must not be sold. If the measured weight of the finished dough pieces exceeds a certain value, then the dough sheet plant is stopped and the cutting device subsequently readjusted in order to minimize rejects. This production stop reduces the hourly produced pieces of dough, thus increasing the cost enormously and affects the cost of a finished piece of dough. The dough strand plants known from the prior art can, depending on the dough and size of cut, adhere to approx. 5-20% weight accuracy per dough piece.
    The aim of the invention is to significantly improve this weight accuracy of the individual dough strands and to reduce production costs.

    Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.
    The invention is illustrated schematically below with reference to particularly advantageous, but not limiting exemplary embodiments in the drawings and is described by way of example with reference to the drawings:

Fig. 7 shows an isometric view of an adjusting disc. Fig. 8 shows an isometric view of a knife. FIG. 9 shows an isometric view of a driven shaft support. FIG.
    Fig. 1 shows an apparatus 10 according to the invention in isometric view. The device 10 comprises a holding element 2, which is designed as a bar with a round cross-section and is held at the ends of two side parts 21 (FIG. 9). The side parts 21 are fixed to the frame 22 of the device 10, wherein the holding element 2 is arranged along the width of a conveyor belt 23 above this at a distance parallel to the width of the conveyor belt 23. In operation, a dough band (not shown) is placed on the conveyor belt 23, which is conveyed along the longitudinal direction thereof past the device 10 or through it.
    The device 10 further comprises four equally formed cutting units 1a, 1b, 1c, 1d, which are fastened to the holding element 2 by means of a clamping mechanism 17. Each cutting unit 1a, 1b, 1c, 1d has a knife 3a, 3b, 3c, 3d, which is designed as a cutting disc. The knives 3a, 3b, 3c, 3d are aligned with the cutting units 1a, 1b, 1c, 1d in the direction of movement of the dough sheet or conveyor belt 3 and separate or cut the dough sheet into five sections. The device 10 comprises a shaft 5 which is arranged parallel to the holding element 2 and passes through the blades 3a, 3b, 3c, 3d respectively in the center and drives them in rotation. The knives 3a, 3b, 3c, 3d are connected with a driver 31 to transmit torque to the shaft (Figure 7). The direction of rotation of the blades 3a, 3b, 3c, 3d can be carried out or blocked against or with the direction of movement of the strip of dough.
    The cutting units 1a, 1b, 1c, 1d can after opening the respective
    Clamping mechanism 17 are manually adjusted on the support member 2 and along the length of the rod, so along the width of the dough sheet, moved or removed from the support member 2. This results in a presetting of the width of the cut portions of the dough strip or the position of the knife 3 to dough or to the width of the conveyor belt 23rd
    FIG. 2 shows an isometric view of an embodiment of a cutting unit 1. The cutting unit 1 comprises an adjusting mechanism 4 which adjusts the knife along the axis of the shaft 5 inserted in the central recess of the blade 3 (FIG. 1). By adjusting the blade 3 by the adjusting mechanism, the position of the blade 3 to the cutting device 1 and thus the position of the blade 3 along the width of the strip of dough automatically controlled controlled.
    The adjusting mechanism 4 has a drive, in this embodiment, an electric motor 11, on. The motor 11 adjusts via a connecting element, in this embodiment a chain 13, a mechanical actuating unit comprising a ramp 14 which changes the position of the blade 3 to the position of the cutting unit 1 (FIG. 7). The cutting unit 1 further comprises a tensioning element for tensioning the belt drive or the chain 13, in the embodiment shown in Fig. 5, a chain tensioner 19, on.
    4 shows a section through the main bearing of a preferred embodiment of the cutting unit 1. The cutting unit 1 comprises a blade 3 designed as a cutting disk, which can be driven via a shaft 5 as shown in FIG. The cutting unit 1 further comprises an adjusting mechanism 4 with a mechanical adjusting unit, which changes the position of the knife 3 to the position of the cutting unit 1. The adjusting mechanism 4 comprises an electric motor 11, which is connected via a chain 13 to the mechanical adjusting unit, which in this embodiment is designed as a disk-shaped adjusting disk 15 (FIGS. 6 and 7). The adjusting disk 15 is rotatably mounted on the driver 31 of the blade 3 independently of this in the axis of the blade 3 (FIG. 7). The adjusting disk 15 has a toothing on the circumference into which the chain 13 engages and, when the motor 11 is driven, rotates the adjusting disk 15 over a defined circumferential section in its axis, that is to say in the axis of a shaft 5 inserted in the recess of the blade 3. The adjusting disk 15 is arranged at a distance along the axis of the knife 3 to the knife 3. On one of the end faces of the adjusting disk 15, three ramps 14 are distributed uniformly over the circumference. The ramps 14 have a circular course with respect to the center of the adjusting disc 15, thus extending along the same radius and have a same constant pitch. The ramps 14 have an ascending height when viewed in the clockwise direction, and are therefore thicker at the end which is further in the clockwise direction, along the axis of the adjusting disk 15, than at the other end. On the blade 3, three ramps 14 formed opposite to the ramp 14 are formed, each of which abuts against the respective ramp receptacle 18 opposite ramp 14.
    When adjusting the adjusting plate 15 by the motor 11 via the chain 13, the adjusting plate 15 is rotated in its axis on the ramps 14 seen in a clockwise direction over a peripheral portion. Due to the slope of the ramps 14, the ramp receptacle 16, which is secured against rotation, is adjusted along the axis of the adjusting disk 15 or the knife 3 or along the width of the dough sheet and the shaft 5 and thus the position of the knife 3 to the cutting device. 1 changed or the distance X increases and thus changed the cutting width of the pieces of dough. If the adjusting disk 15 is rotated counterclockwise, the distance X is reduced analogously.
    In the embodiments of the device 10 and the cutting unit 1 shown in FIGS. 4, 5 and 6, the adjusting mechanism 4 has three return springs 18, wherein the return springs 18 in the same radius with respect to the central axis of the blade 3 evenly are arranged distributed (Fig. 8). The force of the return springs 18 acts counter to the slope of the ramps 14, so that they cause a return of the blade 3 against the drive of the motor 11 or change the position of the blade 3 to the cutting unit 1, so that the distance X between the blade 3 and the adjusting 15 is reduced. The return springs 18 are, for example, as shown in Fig. 7 via intermediate parts respectively connected to the blade 3 and the adjusting disk 15. Furthermore, by the force effect of the return springs 18, the position of the blade 3 can be fixed. Thus, an unwanted adjustment of the knife 3 can be prevented by the force of the dough or other influences. At the same time, the return springs 18 provide overload protection against the components used.
    FIGS. 3 and 3 a each show an end or extreme position of the knife 3 adjusted by the adjusting mechanism 4. The position of the knife 3 relative to the cutting device 1 can be adjusted by the distance X in the direction of the axis of the knife 3 formed as a cutting disk , The distance X or the position of the blade 3 to the cutting unit is preferably adjustable by less than 100mm, preferably less than 32mm, more preferably less than 16mm, wherein the adjustment advantageously in steps of less than 1mm, preferably less than 0.1 mm , he follows.
    Alternatively, the adjustment of the blade 3 can also be effected by other mechanical actuating units, which alternatively comprise a ball ramp, a helical gear, a worm or a threaded spindle, or these or the ramp 14 can also run helically on an end face of the adjusting disk 15. The ramps 14 may alternatively be helical or have a profiled design. Furthermore, the adjustment can also be made by a pneumatic or hydraulic cylinder.
    Alternatively, the blade 3 or the cutting disc can also be driven via the underlying belt or a drive roller.
    An application of the device 10 according to the invention provides that it is arranged or used within a dough sheet plant. For example, the device 10 may be presented with a weighing device with which the measurement of the mass distribution along the width of the strip of dough moving along its longitudinal direction is detected. The cutting width of the cutting unit 1 or of the cutting units 1a, 1b, 1c, 1d can then be predetermined, for example, via a control unit by the determined mass distribution of the strip, so that the endless sections or subbands cut by the device 10 along the longitudinal direction of the strip have the same mass have per unit length of the sub-band. About the transport speed and the timewise mass distribution of the dough strip and the arrangement of the device 10 relative to the weighing device can always time-dependent pieces of dough or subbands with the same mass, by adjusting the cutting units 1a, 1b, 1c, 1d are generated. As a result, the cuts of the device 10 or of the cutting units 1a, 1b, 1c, 1d are already anticipated and always produced without rejects and weight. For example, in the event that a dough area to be cut becomes too heavy, the cutting width for this area can be reduced by adjusting a knife 3a, 3b, 3c, 3d and thus the weight can be adjusted. Since this can have an effect on the cutting width of adjoining sections, the cutting width of the further sections and thus the position of the other blades 3a, 3b, 3c, 3d relative to the respective cutting units 1a, 1b, 1c, 1d can advantageously be the same value in the same Direction as the first knife to be adjusted. As a further measure, alternatively, the longitudinal section of the dough strip or, the sub-bands can be adjusted. For example, on the basis of the determined mass distribution, the blade 3a of the cutting unit 1a is adjusted by 0.5 mm, whereby the blades 3a, 3b, 3c of the adjacent cutting units 1b, 1c, 1d are automatically adjusted or adjusted by 0.5 mm, too to produce the other adjacent pieces of dough or produced sub-bands weight-accurate. As described, however, a different adjustment of each separating unit 1a, 1b, 1c, 1d can also be determined and predetermined by the control unit in order to generate five subbands with the same mass per unit length for all subbands in the embodiment of FIG.
    The weighing unit can be designed, for example, as a weight-measuring unit or determine irregularities or differences in weight along the width and / or length of the dough strip by means of a laser scanner or X-ray radiation and from this specifies a different cutting width for the sections of the dough strip.
    Advantageously, can be provided by an accurate, as possible backlash-free storage within the adjustment 4. Weites can by high translations in the longitudinal adjustment of the knife 3a, 3b, 3c, 3d or the adjusting mechanism 4, for. by integrating a gear in the motor 11 or by selecting the translation between the adjusting disk 15 and motor 11, the accuracy of the slitter can be increased controllability. Since the belt speeds in dough sheeting systems in the area of longitudinal cutting units, such as the device 10, normally run relatively slowly (up to about 20 m / min), a relatively high translation for the adjustment can be used to increase the accuracy and to reduce the adjustment speed.
    Alternatively, other blades 3 such as a cutting disc or a straight-guided knife or even an ultrasonic knife can be used. Again, a parallel arrangement of several cutting elements is advantageous.
    It is advantageous if the exact position of the adjusting mechanism 4 or of the blade 3 is known in order to be able to better control the control. For this purpose, a rotary encoder or a linear sensor with a corresponding resolution in the adjustment mechanism 4 and / or the motor 11 are integrated.
    The control unit can advantageously be designed or programmed in such a way that upon adjustment of one of the knives 3a, 3b, 3c, 3d by the control unit by a defined value, the knives 3a, 3b, 3c, 3d opposite to the adjustment direction are automatically adjusted by the same value ,
    Furthermore, the device 10 can optionally have a control sensor system and a position sensor or a position sensor per knife 3a, 3b, 3c, 3d or cutting unit 1a, 1b, 1c, 1d. With the position sensor, the position of the blade 3 or the blades 3a, 3b, 3c, 3d detected and transmitted to the control sensor. The adjustment of the blade 3 or each blade 3a, 3b, 3c, 3d can then be checked by the position sensor and transmitted to the control sensor system and thus a more accurate positioning of the blades 3a, 3b, 3c, 3d or the respective adjustment mechanism 4 can be achieved or whose position is readjusted. The position indicators may be designed as absolute sensors and the position of the knives 3a, 3b, 3c, 3d absolutely, for example at a set zero point, e.g. measure one end of the width of the strip of dough or be designed as a relative sensor and determine the position of the knife 3a, 3b, 3c, 3d with each other.
    Optionally, the device 10 may comprise a 3D laser scanner or a unit for video analysis of the geometry of the dough sheet, with which the geometry of the dough sheet, ie the thickness, the width, the deviation of the thickness across the width, etc. is detected. By means of the control unit, the regulation of the position of the blade 3 or the blades 3a, 3b, 3c, 3d can then be adjusted by means of the 3D laser scanner or the unit for video analysis of the dough sheet geometry and so, for example at different thickness the width of the dough strip, sections of the same weight or sub-bands with the same weight per unit length, but for example different width, to be cut.
    As an alternative to manual adjustment of the cutting unit 1 on the holding element 2, the device 10 may have a positioning unit with which a pre-positioning of the cutting unit 1 on the holding element 2 is automatically adjusted. Thus, for example, the pre-positioning can be adjusted depending on the product to be produced and, for example, the cutting units 1a, 1b, 1c, 1d are positioned at the same distance from each other. The adjustment of the cutting width or the blades 3a, 3b, 3c, 3d can then further be fine adjusted according to the specific mass distribution along the width of the dough strip. This allows automatic product change without manual intervention. Through an automated
    Pre-positioning can be a rough control with a large adjustment (1600mm or larger) can be realized and the fine control (<0,1mm) done by means of the adjustment mechanism 4.
    Optionally, it can further be provided that the retaining element 2 designed as a rod is continued beyond the region in which the dough sheet is transported within the device. On the retaining element 2, no dough strip is then positioned below it over a certain length, thus forming a parking area for a cutting unit 1. If, due to the change of a product to be produced or due to the mass distribution along the width of the dough strip, one of the cutting units 1a, 1b, 1c, 1d is no longer needed, it can be moved manually or by means of the positioning unit into the parking area, so that the Knife 3a, 3b, 3c, 3d of the displaced cutting unit 1a, 1b, 1c, 1d is no longer in contact with the dough and remains there until it is needed again. Alternatively, the knife 3a, 3b, 3c, 3d of the no longer required cutting unit 1a, 1b, 1c, 1d can be lifted off the dough sheet.
    Furthermore, the device 10 may also have a simple exchange system in order to be able to easily change the number of cutting units 1a, 1b, 1c, 1d arranged on the holding element 2. This is possible, for example, by means of a shaft cantilevered on one side, which allows the blades 3a, 3b, 3c, 3d designed as a cutting disk to be simply pushed onto the shaft.
    In order to be able to realize a simplified control and also be able to use more favorable drive components, a filtered position control can be used and integrated into the control unit or the control of the motor 11 or the adjusting mechanism 4.
