    专利说明:

    The invention relates to a method and apparatus for cross cutting a moving at a conveying speed in the conveying direction strand adhering to each other bands of a food product, in particular a pasty food product, such as industrially produced cheese. This strand is cut with a cross-cutting across the width cutting blade, which performs a cross-cutting one of the conveying speed and the height of the strand appropriate cutting movement, the cross cutter is guided at conveying speed parallel to the conveying direction and the cutting movement is performed at a cutting speed perpendicular to the conveying direction. With this cutting movement, a stack of juxtaposed slices of the food product is separated from the head of the strand. The invention also relates to the food product produced by the process. Such cross-cutting devices are known in particular from the production in stacks of superimposed and packaged cheese slices, so-called "slice on slice" stack, as they are delivered, for example, to fast food restaurants. To produce such stacks, a wide cheese strip is first produced, which is subsequently cut longitudinally into individual strips. The strips are superimposed with slight misalignment to facilitate later lift-off and then fed to the cross cutter, which cuts the continuously fed, stacked processed cheese strips into individual stacks of pre-set length. In the stacks, the individual discs have a rectangular, in particular an at least almost square format. Subsequently, the stacks are transported to the next station by means of the conveyor belt.
    On the other hand, it is known that in particular for the mass production of sandwich ready pre-sliced cheese slices are required in other formats. A triangular format for sandwiches has recently gained acceptance because in this format the ingredients are particularly visible to the customer. The cutting of corresponding triangular disks is known, for example, from US 2006/0 042 434 A1, the resulting stack of triangular disks from US Pat. No. 5,337,606 being apparent.
    In this procedure, a relatively high stack of a plurality of individual slices is guided in a lying position by a knife device that completely cuts through the stack. Depending on the consistency of the cheese causes such a cut due to the strong pressure forces a more or less strong deformation of the stack, which can be handled only conditionally machined in the cut state. In addition, in cuts made in this way with a wire or a knife, the cut edges of the cheese slices fritter, which suffers the attractiveness of the product.
    The object of the invention is therefore to propose a method to implement on the one hand a cross-section and on the other hand a diagonal cut through a stack of juxtaposed slices of a food product, which carries out the cuts with great precision and high quality. In addition, it is the task to propose a corresponding device.
    These objects are achieved by the method according to claim 1 and the device according to claim 5. The dependent claims each describe preferred embodiments.
    The basic idea of the inventive method or the device is in the also the width of the strand spanning Diagonalschneidmesser, which is held together with the cross cutter on the common blade carrier and therefore simultaneously performs a cutting movement with the cross cutting knife. In this case, it is achieved by the diagonal alignment of the diagonal cutting blade that the stack of rectangular disks cut off from the strand by means of the cross cutting knife is cut into two partial stacks of substantially triangular disks.
    The discs have a "substantially triangular" format because a apex of the triangle, particularly the tip opposite the hypotenuse, can be somewhat "flattened" to allow, for example, easier gripping of the disc from the stack. The "flattening" is achieved, for example, in that the diagonal cut is not guided exactly from one corner of the rectangular stack to the other corner, but starts and / or ends offset slightly at the longitudinal edge. For the edges resulting from flattening, lengths of a few millimeters are sufficient to facilitate gripping.
    Furthermore, "triangular" does not necessarily mean that the edges of the triangle must be straight. So even when using knives with a fixed blade - instead of wire - it is possible to produce edges with any desired course.
    As stated, the flattened tip simplifies the handling of the individual disc. It is also advantageous if the individual bands each offset slightly and not flush with each other. The offset between the individual discs is also in the order of a few millimeters, wherein the offset exists only at the lateral edges, the discs on the cutting edges, however, lie flush on top of each other. This leaves grip edges in the stacks that further facilitate the manual peeling of a single slice from the stack, thus making the product more comfortable to process. According to the claim, the method is characterized in that the diagonal cutting knife spanning the width of the strand and arranged at an angle to the transverse cutting knife carries out the cutting movement while cutting the stack diagonally. The diagonal cut cuts the stack into two partial stacks formed by triangular disks, whereby the diagonal cut does not necessarily have to completely cut through the lowest slice of the stack, ie the last slice to be cut.
    Finally, it is advantageous for the further handling of the truncated stack when the diagonal cutting knife completely cuts through all the slices of the stack except for the lowermost slice, but only cuts or perforates the lowermost slice. Thus, both separate sub-stacks are on a common, only trimmed disc, which holds both stacks together because of the adhesive properties of the food, especially the cheese. On this not completely severed disc, the double stack can be relatively reliably removed on the conveyor belt, without the stack tip over. The product can also be packaged in the form of these double stacks for the consumer, who can first lift all triangular discs from the stacks until he reaches the bottom, which he then very easily at the "breaking point" can tear apart.
    The cohesion of the two sub-stacks in the stack is so large that the stack can also be tilted in a downstream stacker device and / or gripped and piled with appropriate means to another pile. Towers of several stacks can then be packed and made available to the consumer in larger containers. So portions of several kilograms can be produced, as they are needed especially for fast food chains.
    In contrast to the diagonal section, it is advantageous, if not essential, that the cross section guided with the cross-section completely separates the stack from the head of the moving at conveying speed in the conveying direction strand. In order to support the separation of the strand, the cross cutting knife can perform a small pushing movement in the conveying direction after cutting, which pushes the stack consisting of two partial stacks something.
    In another embodiment, however, the separation is advantageously carried out such that the strand is fed at a conveying speed of a first conveyor belt, while the cut stack of a second subsequent conveyor belt with a discharge speed which is at least slightly greater than the conveying speed, is dissipated. With the lowermost disc which holds together the two partial stacks and which has not been completely severed, the band transition and the acceleration to the discharge speed can be accomplished without problems. In this way, the cut double stacks are separated for further processing.
    The transition between the conveyor belts is advantageously at the position at which the cross cutter completes the cut. Thus, the cross cutter can dive into the gap between the two conveyor belts and cut completely through the stack. It is not absolutely necessary because of the pasty consistency of the food product that the severing cut is performed against a hard pad.
    In order to stabilize the two partial stacks during the cut, and because of the particular paste-like consistency of the food product, which easily leads to adhering to the knives, it is particularly advantageous if both partial stacks during the cut and during the subsequent lifting of the knife the cut from above are applied by means of a hold-down. Such a hold-down can be attached to the knife carrier and is carried along accordingly. The acting force is caused in a particularly simple case by springs, which stretch after application of the blank holder on the stack during further cutting. Thus, a spring-loaded hold-down is used, which is attached to the knife carrier of the cross cutter and prevents lifting of the stack.
    The inventive concept for cutting triangular stacks, which is followed by the production of a superimposed product strip from bands, has obvious advantages: Thus, the combination of cross cutting and diagonal cutting in a tool an additional device for pure diagonal cutting saved would join a previously known cross cutter. The device according to the invention can accordingly be easily inserted into a conventional production line. Existing devices for pure cross cutting can be retrofitted with simple means to the diagonal cutting blade, which is mounted in the simplest case to the common blade carrier.
    Moreover, it is advantageous if the two angularly arranged knife are equipped with solid blades and not with cutting wire. With the rigid blades, particularly sharp cuts and correspondingly clean cut edges can be achieved on the food product, which further increases the attractiveness in the eyes of the consumer. These solid knives also make it possible to cut through separating layers of film that are provided between the individual panes. Another advantage of the rigid blades is that they do not necessarily have to be straight, but depending on the requirements also curved, wavy or jagged - therefore any - can be designed so that discs can be made with a correspondingly shaped edge. The devices designed in this way are even suitable for cutting particularly thick strands or massive products. In the case of cheese products, cutting heights of up to 15 cm are available, with up to 200 cuts per minute being easily carried out with the devices according to the invention.
    Further features and advantages will become apparent from the following description with reference to the figures. Show it:<Tb> FIG. 1 <SEP> a knife carrier with transverse and diagonal cutting knife,<Tb> FIG. 2 <SEP> a slice of the product according to the invention and<Tb> FIG. 3 <SEP> a knife carrier built into a device.
    Fig. 1 shows first a knife carrier 1, which is held by a suspension 2 to the device for transverse and diagonal cutting and is moved as a complete unit by means of a drive means along a predetermined movement curve in a cutting movement. In the figure, only one strand 3 adhering to each other bands 4 of a food product, here processed cheese, shown, from the head of a stack 5 was cut and separated.
    On the knife carrier 1, a width of the strand 3 spanning transverse cutting knife is held on the one hand, which has two lateral supports 6 and a blade 7. At two other brackets in the same way a likewise the width of the strand 3 spanning and arranged at an angle of about 45 ° to the cross cutter diagonal cutting blade is held on the blade carrier 1, which has a corresponding rigid blade 8. Cross cutter and Diagonalschneidmesser are fixedly coupled to each other by means of the knife carrier 1, wherein the blade 8 of the Diagonalschneidmessers is slightly higher than the blade 7 of the cross cutter, so that the diagonal cut is not carried out completely through the stack 5 to the ground.
    Because of the rigid coupling, the diagonal cutting blade completes the cutting movement accordingly, with the cutting movement of the diagonal cutting blade leads to a diagonal section 9 through the stack 5, so that it is divided into two partial stack 10 of triangular slices. The two partial stacks 10 are acted upon during the cutting movement and during the subsequent excavation of Diagonalschneidmessers from the section from above by means of a hold 11, wherein the hold-down 11 lays on the top disc of the stack 5 and there remains under tension of springs, while the diagonal cutting blade is guided in the stack 5.
    In the present case, the diagonal cutter and the hold-down 11 are mounted on a separate mounting plate 12 which is releasably secured to the knife carrier. After removing the mounting plate 12 with Diagonalschneidmesser and hold-down 11, the device can be operated solely with the Querschneidmesser. On the other hand, any device for diagonal cutting can be retrofitted with it.
    Already from Fig. 1 it can be seen that the stack 5 is not exactly diagonal cut from corner to corner, but with a slight offset. This results in two sub-stacks of triangular discs, the tips of which are somewhat "flattened" to ensure easier gripping the disc from the stack can. Such a flattened edge 13 can be seen on the separately shown triangular single disc 14 in Fig. 2. The discs of the second sub-stack have a corresponding format.
    Fig. 3 shows now the complete device for transverse and diagonal cutting with the knife carrier 1, which is held on a drive means 15. In addition, in Fig. 3, a first conveyor belt 16 is shown, on which the strand 3 with a conveying speed v1 the blades in the conveying direction (arrow A) is supplied. The drive means 15 moves the blades in a cutting motion that follows a "flying saw". This cutting movement is performed at a conveying speed parallel to the conveying direction A and at a cutting speed perpendicular to the conveying direction, so that a vertical cut is produced in the stack 5 in spite of the movement. With the cutting movement, the stack 5 formed by slices of the food product, consisting of two partial stacks, is separated from the strand. The device has a second conveyor belt 17, via which the cut stack 5 with a discharge speed v2, which is greater than the conveying speed v1, is likewise removed in the transporting direction A for further processing. The resulting between the strand 3 and the stack gap 18 is due to the different conveying speeds and the cut on the band transition 19.
