Definitions
- the invention relates to a method and a device according to the preambles of claims 1 and 8.
- a method and a device of the aforementioned type are known for example from US-A-3842698 known.
- the device as used in the Figures 10 to 14 of the aforementioned document is disclosed, has two clipboards, which can be transferred from opposite directions of each of a waiting position next to the food strand cross-section in their receiving position below the food strand.
- the clipboards which are displaceably mounted in the feed direction in addition to a direction perpendicular to the feed direction, are used in the known method to take a complete portion of the cut slices in a vertically stacked form, in order to then transfer them to a conveyor device comprising a plurality of intermediate elements encircling straps to hand over.
- the transfer element enters from the side facing away from the food strand underside of the conveyor into spaces between adjacent straps and also penetrates spaces in the fork-shaped clipboard to get in this way to the underside of the formed portion approach and take over supporting.
- the two clipboards are used to continuously feed the food strand, ie without interruptions in the removal of finished portions. While a stack is still on the one clipboard or is just being taken over by the transfer element, the other clipboard is already in a waiting position or a receiving position displaced below the cross section of the food strand, so that the cutting process can be continued without interruption.
- the invention has for its object to provide a method and apparatus for cutting a food in slices, in which can be achieved instead of the formation of vertical slice stack other storage images.
- the above object starting from a method of the type described above, achieved in that on the clipboard from the cut slices a shingled disc assembly is generated, wherein the clipboard is moved transversely to the feed direction. The portion is thereby transferred in an unfinished state of the clipboard to the conveyor, wherein the transferred portion after it has been taken over by the conveyor, completed by cutting and adding at least one other disc and then discharged.
- the method according to the invention thus combines the temporal advantages, ie the high cutting performance, with the use of a clipboard, on which the panes are temporarily arranged, with the optical attractiveness of a shingled pane arrangement.
- a shingled disc arrangement in the context of the present application, all possible storage images are to be understood, in which the discs do not form a vertically aligned stack of discs with always aligned disc edges.
- a shingle in the context of this application is thus also a fan, a shingled arrangement or a partially meandering storage the same disc to understand, so that a total of air trapped and therefore voluminous disc portion is generated, which is practiced especially in wafer-thin slices to later to facilitate their separation from each other.
- the production of a finished portion thus takes place in two phases, namely a phase in which (initially) the clipboard serves as a support member for the portion which is being formed.
- a phase in which (initially) the clipboard serves as a support member for the portion which is being formed After a certain time, that is to say the generation of a certain number of slices of the portion which is currently being formed, it is transferred to the conveyor during the cutting process, that is to say, in particular also with the feed continued and the rotation of the knife unchanged, which is therefore uncritical because the deposit, that is to say the addition of further slices, takes place on the upper side of the portion, whereas the change in support from the clipboard to the conveyor takes place on the underside and therefore can be made such that it does not interfere with the top of the resulting portion causes.
- the expenditure on equipment is reduced as well as the requirements for the control, since compared with the US-A-3842698 in turn can be dispensed there existing component, namely the second clipboard.
- the clipboard is released during the production of a portion, ie before its completion, that is to say is no longer needed for the current portion, it is possible to put the clipboard already in the waiting position during the completion of the current portion to bring them to the first portion of the next serving quickly after the completion of the current portion in the collection position.
- the inventive method is preferably carried out with a single clipboard and a plurality of slices, ie a partial portion is in common, ie all slices more or less simultaneously and contiguous of the clipboard directly, ie without the interposition of one of US-A-3846698 Passed known separate transfer element.
- a partial portion is in common, ie all slices more or less simultaneously and contiguous of the clipboard directly, ie without the interposition of one of US-A-3846698 Passed known separate transfer element.
- a particularly simple transfer of cut slices from the clipboard to the conveyor is then enabled when support elements of the clipboard enter into spaces between adjacent straps of the conveyor during transfer, with a disc supporting surface of the support elements after transfer below a disc carrying surface of the Riemchen the conveyor is arranged.
- the conveyor is arranged.
- the transfer of cut slices from the clipboard onto the conveyor belt can advantageously be achieved by means of a relative movement between the clipboard and the conveyor running in the feed direction.
- the clipboard when the conveyor is stationary, the clipboard can be lowered correspondingly far or else, when the clipboard is stationary, the conveyor can be moved upwards in the feed direction toward the food strand.
- a combination of the two aforementioned types of movement is possible, in which case - with respect to a stationary machine frame - to move the clipboard and the conveyor in the vertical direction to each other.
- the clipboard can not leave the wait position until the knife has already begun to cut a next slice and is already within the cross-section of the food strand.
- the clipboard can move in a projection of the cross section of the food strand in a direction perpendicular to the feed direction even an already suspended by gravity or even resting on the previously cut slice part of the currently emerging Raised disc with the surface of their support elements again.
- the underlying object is achieved in that the clipboard is movable transversely to the feed direction of the food strand that on her at least partially linearly shingled disc assembly can be generated and the clipboard has the shape of a fork, which formed from a plurality of parallel support elements is that in spaces between adjacent straps enter the conveyor to transfer the portion in an unfinished state from the clipboard to the conveyor, wherein the transferred portion, after it has been taken over by the conveyor, completed by cutting and adding at least one other disc and then discharged.
- the clipboard from a receiving position in which it is the first slice of a new portion can be removed in the course of generating a shingled disc tray successively removable from a waiting position in which they are completely outside a projection of the cross section of the food strand in a the cutting plane is parallel plane.
- the device according to the invention in this case requires an extension of the possibility of movement of the clipboard in the direction in which the finished portion is later typically discharged, as compared to the cycle of movement required for the mere interim picking up of vertical slice stacks, using the conveyor means .
- the inventive device allows a particularly high cutting performance, as the Einschtigweg (distance between the waiting position and the receiving position) is minimized and the subsequent successive movement of the clipboard in the same direction as the Einschintevorgang done, but with a corresponding time delay - corresponding to the attack of the following Slices - can take place.
- the device according to the invention thus implements no reversal of the direction of movement of the clipboard during the operation of the subsequent shingling following the insertion.
- the reversal of motion takes place only when after transfer of a partial portion of the clipboard on the conveyor, the clipboard must be moved back out of the strand cross-section, the then extended path (compared to a method with reversal of motion immediately following the Reaching the recording position) is uncritical, because until the completion of each portion still sufficient time is available to transfer the clipboard back to the waiting position.
- a plurality of cut-off slices can be transferred together directly from the clipboard onto the conveyor device.
- the clipboard has supporting elements which are arranged so that they intersect in intermediate spaces Straps of the conveyor can be positioned, wherein a plane defined by the surface of the support elements extends parallel to a plane defined by the surface of the straps of the conveyor plane. Due to the parallelism of the aforementioned levels, the transfer of the disks from the clipboard to the aprons is made particularly gentle, whereby a very high quality of the filing geometry is achieved.
- the clipboard is fork-shaped and the support members are tine-shaped and arranged on a support beam, preferably welded thereto.
- the mass of the strong to be accelerated clipboard should be kept as low as possible. This is especially true because the clipboard due to the shingled shelf must be significantly larger (longer and / or wider), as in the mere stacking. For this reason, the measured in the feed direction height of the support elements should be smaller than twice, preferably less than 1.5 times, the thickness of the slices to be cut, in particular less than 10 mm, preferably 8 mm, more preferably between 4 mm and 6 mm lie.
- the mass of the clipboard should be less than 0.5 kg, preferably less than 0.3 kg.
- the support elements comes next to stainless steel or light metal alloys and fiber-reinforced plastic, in particular using carbon fibers, in question.
- the clipboard is mounted displaceably in a catch frame perpendicular to the feed direction and the catch frame is slidably mounted on a machine frame in the feed direction, wherein the catch frame has two laterally arranged next to the conveyor linear guides for the clipboard.
- catch frame in the sense of the present application is not necessarily a self-contained execution of struts to understand. Rather, in particular, a three-sided, ie U-shaped arrangement of struts meant, which makes sense to realize storage facilities for the clipboard on both sides next to the conveyor can.
- a drive with the help of a timing belt in question which is characterized by a slip-free running even at maximum dynamics of movement.
- the conveyor is followed by a likewise formed in the form of a belt having a plurality of mutually parallel straps discharge device.
- the conveyor may be stored together with the discharge on a discharge frame, which in turn adjustable on a machine frame, in particular slidably and / or is pivotally mounted.
- the support elements of the clipboard should have a length measured perpendicular to the feed direction, at least twice, preferably at least three times, perpendicular to Feed direction measured width of the cut slices corresponds.
- the clipboard In order to avoid temporal problems in the often time-critical phase of "putting in” of the clipboard, the clipboard should - starting from its waiting position - in the same direction in a projection of the cross section of the food strand in a plane formed by the support elements of the clipboard, be introduced, as the cut slices are discharged from the conveyor.
- the same purpose of a relaxation of the cutting operation is the measure, according to which the clipboard enters from one side into a projection of the cross section of the food strand in a plane formed by the surface of the support elements of the clipboard, which is opposite to a side on the Due to gravity, an emerging disc will detach from the food strand due to gravity.
- FIGS. 1 to 5 partially in a perspective view and in the FIGS. 6 to 10 in a side view shown device 1 for cutting a food strand 2 (for example, sausage, cheese, etc.) has one only in the FIGS. 6 to 11 illustrated cutting device 3, which has a rotating about a rotation axis 4 blade 5, for example in the form of a sickle blade, but alternatively also in the form of a planetary-like rotating on a swing arm circular blade.
- a cutting edge 6 defines by the rotation of a cutting plane 7, which is aligned perpendicular to a longitudinal axis 8 of the food strand 2.
- the longitudinal axis 8 runs parallel to the feed direction illustrated by an arrow 9, into which the food strand 2 is advanced onto the knife 5 of the cutting device 3 with the aid of a feed device 10 shown only schematically.
- the feed device 10 has at its upper end in the feed direction (arrow 9) vorschiebbare gripper device 11, the gripper hooks 12 are buried in the knife 5 facing away from the rear end of the food strand 2 and thus form a positive connection.
- Both the gripper device 11 and two feed belts, not shown, which support the food strand 2 laterally and are equipped with interlocking means (spikes) to prevent slippage, have a configuration according to the prior art and require no further explanation at this point.
- the food strand 2 with the aid of the feed device 10 with great precision in the feed direction (arrow 9) are advanced, which is important for achieving a high accuracy in the geometry of the slices to be cut.
- the clipboard 15 has the shape of a fork and has a plurality of parallel and equidistant from each other tine-shaped support members 16 and a perpendicular to the support members extending and connected to the support beam 17.
- the clipboard 15 is mounted in a collecting frame 18 in such a way that it is perpendicular to the feed direction, that is parallel to the cutting plane 7 slidably.
- the support beam 17 is mounted at both longitudinal ends in each case a linear guide 19 which is in each case in the interior of a longitudinal strut 20 of the collecting frame 18.
- the drive of the clipboard 15 in the direction of the linear guides 19 is effected by means of a respective timing belt 21, which is connected on both sides of the clipboard 15 by means of a coupling element with the support beam 17.
- the collecting frame 18 is as such in a direction (double arrow 22) parallel to the feed direction (arrow 9) displaceable within a in FIG. 1 schematically, in FIG. 6 but not shown machine frame 23 slidably.
- the adjustability is carried out, for example, by means of a hydraulically or pneumatically actuated cylinder 24 to the respective piston rod 25, a lower part 26 of the collecting frame 18 is connected.
- FIG. 1 in which only the actually cranked piston rods 25 (which in the FIGS. 6 to 11 For the sake of simplicity, are shown only in a straight line) are visible, the storage and adjustment of the collecting frame 18 by means of two cylinders 24 in the FIGS.
- the conveyor 14 includes a plurality of equidistant from each other and arranged on its upper side a common conveying plane 28 forming apron 29, which are guided around two annular grooves for the straps 29 deflecting rollers 30, 31, one of which is driven by means of a servo drive.
- the clear distance between adjacent straps 29 is slightly larger than the measured perpendicular to the longitudinal extent of the fork-shaped support members 16 width of the support members 16. Since the pitch of the straps 29 of the conveyor 14 corresponds to the pitch of the support members 16 of the clipboard 15, the latter can therefore in the interstices dipping between adjacent straps, which is crucial for the transfer of cut slices described below from the clipboard 15 to the conveyor 14.
- the discharge device 13 as well as the conveyor 14 comprises a plurality of straps 32, whose width, however, is considerably greater than that of the straps 29 of the conveyor 14.
- a guide roller 33 of the discharge device 13 is arranged so close to the guide roller 30 of the conveyor 14 that the Riemchen 29, 32 do not collide with each other, with a trouble-free and the disc assembly not impairing Transfer from the conveyor 14 to the discharge device 13 is ensured.
- the discharge device 13 is mounted in a discharge frame 34 which is mounted pivotably about the axis of rotation of a guide roller 35 in the machine frame 23.
- the deflection roller 33 of the discharge device 13 associated with the end of the discharge device 13 is provided with a in FIG. 1 covered by a machine housing in FIG. 6 However, visible further cylinder 36 (hydraulically or pneumatically operated) or its piston rod 37 is connected. An extension of the piston rod 37 from the cylinder 36 causes both an upward pivoting of the discharge frame 34 and a parallel displacement of the conveyor 14, which is also coupled to the piston rod 37.
- a receiving plane 39 of the conveyor 14 formed by the surface of the aprons 29 always remains in its parallel alignment with the cutting plane 7 , that is perpendicular to the feed direction (arrow 9). Due to the articulated connection between conveyor 14 and discharge device 13, the angle enclosed between the receiving plane 39 and a discharge plane 40 formed by the surface of the straps 32 changes depending on the position of the conveyor 14, that is the position of the piston rod 37 of the cylinder 36.
- Another synchronizing belt 40 represents a coupling between the deflecting roller 30 of the conveying device 14 and the deflecting roller 35 of the discharging device 13.
- portions consist of five shingled successive individual slices. Due to the omission of the cutting device 3 and the feed device 10 including the food strand 2, the interaction between the conveyor 14, the clipboard 15 and the discharge device 13 is particularly clearly visible.
- FIG. 1 shows a situation in which a portion just completed and formed from five slices rests on the conveyor 14. For each blade revolution, a slice is separated from the food strand 2, with between two successive ones Cut the aprons 29 of the conveyor 14 by the "Schindeltreatment" in a direction R1 on the discharge device 13 are moved on to produce only a partially overlapping so-called shingled or shingled tray.
- FIG. 1 shows a situation in which the knife 5 has just completed the section of the last, uppermost disc and the clipboard 15 is still in its waiting position in which it - by appropriate control of the timing belt 21 - has a maximum distance from the discharge device 13.
- the on the control of the non-visible cylinder 24 and consequently the movement of the associated piston rods 25 to be adjusted height of the collecting frame 18 and thus the top of the support members 16 of the clipboard 15 is set at this moment that the clipboard 15 by activating the drive of Synchronous belt 21 can be moved in a direction R2 to the discharge device 13 to its collection position, without touching the uppermost slice of the conveyor 14 lying on the completed portion.
- the clipboard 15 is shown in its catchment position in which it is located vertically below the face of the food strand and therefore can receive a straight cut slice on the surface of its carrying elements 16. Since the rotation of the knife 5 as well as the feed movement of the food strand 2 during the entire cutting process (ie until the food strand 2, apart from a remnant in which the hooks are 12 are completely cut), with constant speed, ie without change in the Angular velocity, takes place, the clipboard 15 must be brought within a very short time, ie between the generation of two discs from their waiting to the Auffang ein. This requires a very large dynamic in the movement of the clipboard 15, which is made possible by a high-performance servo drive for the timing belt 21.
- FIG. 3 It can be seen that a second slice of the portion currently being formed has already been cut off and placed on the clipboard 15.
- the clipboard 15 In order to also produce a shingled storage on the clipboard 15, the clipboard 15 has moved in the direction R3 perpendicular to the feed direction to the shingles, so that the second disc overlaps the first slice of the new portion only partially.
- the preceding finished portion Due to the further continued movement of the conveyor 14 and the discharge device 13, the preceding finished portion is now substantially completely on the discharge device 13th
- the clipboard 15 is now transferred to a discharge position in which the distance to the waiting position is maximum and the support elements 16 - are dipped - by upward movement of the conveyor 14 - in the spaces between adjacent straps 29 so that the previously with the support members 16 of the clipboard 15th in contact discs were transferred to the surface of the straps 29.
- the preceding completed portion has meanwhile moved further on the discharge belt 13 in the direction of the deflection roller 35, in order subsequently to be passed on to a packaging device in which the disks are welded into a self-adhesive film package.
- FIG. 5 shows how a fourth slice has been added to the currently formed portion.
- the still unfinished portion rests solely on the conveyor 14 and has been moved to maintain the shingling in comparison with the previous disc section a piece in the direction R1 to the discharge device 13.
- the directions R1, R2 and R3 are identical.
- the clipboard 15 was meanwhile, while retaining its distance from the cutting plane, it is withdrawn from the emptying position to an intermediate position, avoiding any contact with the cut-off wheels. Starting from the intermediate position of the clipboard 15 shown, it can be raised again into its waiting position in a next step, which is done by raising the entire catch frame 18. After cutting off another, fifth slice completing the current portion is again the starting situation according to FIG. 1 reached.
- FIGS. 6 to 11 In contrast to the production of shingled portions according to the FIGS. 1 to 5 will be in the FIGS. 6 to 11 now explains the generation of portions consisting of exactly vertically stacked discs. Although such a procedure is not according to the invention, it should be explained here for the sake of clarity. Moreover, with the device according to the invention, the generation of a stacked disc arrangement according to the sequence according to the FIGS. 6 to 11 possible. Also, such portions are welded after the device according to the invention in a packaging device in plastic film packaging and offered as self-service packaging units in supermarkets.
- FIG. 6 Comparable with the situation according to FIG. 1 also shows FIG. 6 a completed portion located on the conveyor 14.
- the knife 5 is still within the cross section Q of the food strand 2, but will leave this at the next moment, then again penetrate into the meantime a piece of advanced food strand 2 and begin with the separation of the next disc.
- the clipboard 15 from the in FIG. 6 shown in the waiting position FIG. 7 transferred shown Auffang ein, ie in particular with great momentum "shot".
- the entry of the knife 5 into the cross-section Q of the food strand 2 thus takes place from the side S1, whereas the clipboard 15 enters the cross-section Q from the opposite side S2.
- FIG. 8 shows a situation how the second slice of the newly formed portion is about to completely separate from the food strand 2.
- the vertically stacked tray according to the FIGS. 6 to 11 merely that the clipboard 15 has to be moved during its use for storage purposes only in the feed direction to keep the distance between the cutting plane and the storage plane for the next resulting disc constant and thus not to change the storage conditions.
- FIG. 9 It is shown how the third slice of the newly formed portion is being separated. The preceding completed portion is transferred to the discharge device 13 and is further moved there.
- the conveyor 14 can be moved with the coupled thereon guide roller 33 of the discharge device 13 again in the feed direction upwards.
- the clipboard 15 can be disabled by the surface of the straps 29 is at least as high as the surface of the support members 16 of the clipboard 15.
- Such a transfer torque is in FIG. 10 shown.
- the clipboard 15 can be further lowered (or the conveyor 14 are raised) to then be pulled out perpendicular to the feed direction from the projection of the cross section of the food strand 2 (intermediate position, see. FIG. 5 ) to return to the in FIG. 11 shown waiting position to be transferred.
- the clipboard 15 can remain until the last slice of the emerging portion is cut off and deposited on the stack. Thereafter, after slight lowering of the conveyor 14 with the completed portion of the necessary space for the subsequent shooting of the clipboard 15 are created, which can then record the next cut disc in their Auffang too.

Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung gemäss Oberbegriffe der Ansprüche 1 und 8.The invention relates to a method and a device according to the preambles of
Ein Verfahren und eine Vorrichtung der vorgenannten Art sind beispielsweise aus der
Die zwei Zwischenablagen werden eingesetzt, um den Vorschub des Lebensmittelstrangs kontinuierlich, das heißt ohne Unterbrechungen bei der Abfuhr fertiger Portionen durchführen zu können. Während ein Stapel sich noch auf der einen Zwischenablage befindet bzw. gerade von dem Übergabeelement übernommen wird, befindet sich die andere Zwischenablage bereits in einer Wartestellung bzw. einer unter den Querschnitt des Lebensmittelstrangs verschobenen Aufnahmestellung, so dass der Schneidvorgang ohne Unterbrechung fortgeführt werden kann.The two clipboards are used to continuously feed the food strand, ie without interruptions in the removal of finished portions. While a stack is still on the one clipboard or is just being taken over by the transfer element, the other clipboard is already in a waiting position or a receiving position displaced below the cross section of the food strand, so that the cutting process can be continued without interruption.
Dies bringt nicht nur Vorteile in Bezug auf die Schneidleistung, die aufgrund der Kontinuität des Schneidvorgangs entsprechend hoch ist, sondern vermeidet auch eine grundsätzlich kritische Unterbrechung des Vorschubs. Schwankungen in der Vorschubgeschwindigkeit, insbesondere ein kurzzeitiges Abstoppen des Lebensmittelstrangs führen nämlich insbesondere bei weicheren und verformbaren Lebensmitteln (z. B. Fleischwurst, Leberkäse, Bierschinken, Käse, o. ä.) aufgrund des materialinhärenten Schwingungsverhaltens im Bereich des Vorschubs zu Problemen. Aufgrund von Kaliberdüsen kurz oberhalb des Messers ist der Vorschub des Lebensmittelstrangs stark reibungsbehaftet. Hinzu kommt der sogenannte "Slip-Stick-Effekt", d. h. bei Überschreitung einer Vorschubkraft kommt es zu einem plötzlichen "Losbrechen", d. h. ruckartigem Vorschieben, des Lebensmittelstrangs. Aufgrund der hohen Dynamik sämtlicher Bewegungen, führen somit LongitudinalSchwingungen am messerseitigen Ende des Gutsstrangs dazu, dass trotz eines gewollten Stopps der Lebensmittelstrang ein geringes Maß unterhalb der Messerebene vorsteht, was zum Abschneiden kleiner Lebensmittelstückchen ("Schnippeleffekt") führt. Insbesondere bei Selbstbedienungsverpackungen in Verpackungsmaterial aus Klarsichtfolie werden derartige Scheibenbruchstücke als erheblicher optischer Mangel nicht akzeptiert. Die Gewährleistung eines kontinuierlichen unterbrechungsfreien Vorschubs ist daher eine wesentliche Voraussetzung für die Erzielung hoher Schneidleistungen sowie vor allem auch erstklassiger Schnittqualität in Bezug auf die stets gleiche Geometrie der abgeschnittenen Scheiben.This not only brings advantages in terms of cutting performance, which is due to the continuity of the cutting process is correspondingly high, but also avoids a fundamentally critical interruption of the feed. Fluctuations in the feed rate, in particular a short-term stopping of the food strand, cause problems especially in the case of softer and deformable foods (eg meat sausage, meatloaf, beer ham, cheese, or the like) due to the inherent vibration behavior in the region of the feed. Due to caliber nozzles just above the knife, the feed of the food strand is heavily affected by friction. In addition, the so-called "slip-stick effect", ie when exceeding a feed force, it comes to a sudden "break-in", ie jerky advancing, of the food strand. Due to the high dynamics of all movements, longitudinal oscillations at the knife-side end of the Gutsstrangs lead to that despite a deliberate stop the food strand projecting a small amount below the knife level, resulting in the cutting of small food pieces ("Schnippeleffekt"). In particular, in self-service packaging in packaging material from plastic wrap such disc fragments are not accepted as a significant optical defect. Ensuring a continuous, uninterrupted feed is therefore an essential prerequisite for achieving high cutting performance and, above all, first-class cutting quality with regard to the always identical geometry of the cut-off wheels.
Während letztgenanntes Problem somit bei dem Verfahren gemäß der
Darüber hinaus ist aus der
Während bei den Verfahren bzw. Vorrichtungen gemäß den beiden vorgenannten Dokumenten lediglich vertikale Stapel von Scheiben als fertige Portionen erzeugt werden können, ist es allgemein bekannt, mittels einer Schneidvorrichtung auch eine geschindelte Scheibenanordnung zu erzeugen. Derartige Schindel können als lineare Reihe von sich teilweise überlappenden Scheiben aber auch als kreisförmige Schindel nach Art eines Fächers erzeugt werden. Grundsätzlich sind auch beliebige andere Ablagebilder denkbar, wobei bei den bekannten Vorrichtungen das Portionierband, auf dem unmittelbar nach dem Abtrennen der Scheiben deren Ablage bzw. die Portionserzeugung und Vollendung stattfinden, auch in eine Richtung quer zu der Vorschubrichtung bewegbar sein kann. Sollen lediglich lineare Schindelanordnungen erzeugt werden, so reicht die bloße Förderrichtung des Portionierbandes aus. Sollen auch kompliziertere Ablagebilder verwirklicht werden, so kann z.B. das Förderband in eine Richtung quer zu dessen Transportrichtung verschoben werden.While in the methods and devices according to the two aforementioned documents only vertical stacks of discs can be produced as finished portions, it is generally known to also produce a shingled disc arrangement by means of a cutting device. Such shingles can be produced as a linear series of partially overlapping discs but also as a circular shingle in the manner of a fan. In principle, any other storage images are conceivable, wherein in the known devices, the Portionierband on the immediately after the separation of the discs take place their storage or the portion production and completion, can also be movable in a direction transverse to the feed direction. If only linear shingle arrangements are to be produced, then the mere conveying direction of the portioning belt is sufficient. If more complicated storage images are to be realized, for example, the conveyor belt can be moved in a direction transverse to its transport direction.
Als unbefriedigend bei den bekannten Verfahren zur geschindelten Scheibenablage wird es angesehen, dass die Leistungsfähigkeit vergleichsweise gering ist, weil vor dem Beginn einer neuen Schindelportion erst die zuvor vollendete Schindelportion unterhalb des Querschnitts des Lebensmittelstrangs entfernt sein muss, um Kollisionen mit der nächstfolgenden Scheibe zur vermeiden. Aus diesem Grunde sind lediglich vergleichsweise geringe Drehzahlen des Schneidmessers möglich. Wie bereits weiter oben dargelegt, ist ein Stoppen des Vorschubs oder auch eine Verlangsamung der Drehzahl des Messers aufgrund der hohen Dynamik derartiger Schneidvorgänge kein gangbarer Weg.As unsatisfactory in the known method for shingled disc tray, it is considered that the performance is relatively low, because before the start of a new shingle, only the previously completed shingle must be removed below the cross section of the food strand to avoid collisions with the next disc. For this reason, only comparatively low speeds of the cutting blade are possible. As already stated above, stopping the feed or even slowing down the speed of the blade is not a viable option due to the high dynamics of such cutting operations.
Schließlich ist aus der
Ausgehend von dem Verfahren der eingangs genannten Art liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Schneiden eines Lebensmittels in Scheiben vorzuschlagen, bei dem sich anstelle der Bildung vertikaler Scheibenstapel auch andere Ablagebilder erzielen lassen.Based on the method of the aforementioned type, the invention has for its object to provide a method and apparatus for cutting a food in slices, in which can be achieved instead of the formation of vertical slice stack other storage images.
In verfahrenstechnischer Hinsicht wird die vorgenannte Aufgabe, ausgehend von einem Verfahren der eingangs beschriebenen Art, dadurch gelöst, dass auf der Zwischenablage aus den abgeschnittenen Scheiben eine geschindelte Scheibenanordnung erzeugt wird, wobei die Zwischenablage quer zur Vorschubrichtung bewegt wird. Die Portion wird dabei in einem unvollendeten Zustand von der Zwischenablage an die Fördereinrichtung übergeben, wobei die übergebene Portion nachdem sie von der Fördereinrichtung übernommen wurde, durch Abschneiden und Hinzufügen mindestens einer weiteren Scheibe vollendet und anschließend ausgetragen wird. Das erfindungsgemäße Verfahren verbindet somit die zeitlichen Vorteile, d.h. die hohe Schneidleistung, bei der Verwendung einer Zwischenablage, auf der die Scheiben vorübergehend angeordnet werden, mit der optischen Attraktivität einer geschindelten Scheibenanordnung. Unter einer geschindelten Scheibenanordnung im Sinne der vorliegenden Anmeldung sollen dabei alle denkbaren Ablagebilder verstanden werden, bei denen die Scheiben nicht einen vertikal ausgerichteten Scheibenstapel mit stets miteinander fluchtenden Scheibenrändern bilden. Mit einem Schindel im Sinne dieser Anmeldung ist somit auch ein Fächer, eine geschuppte Anordnung oder auch eine teilweise mäandrierende Ablage derselben Scheibe zu verstehen, so dass insgesamt eine Lufteinschlüsse aufweisenden und daher voluminöse Scheibenportion erzeugt wird, was insbesondere bei hauchdünnen Scheiben praktiziert wird, um später deren Trennung voneinander zu erleichtern.In procedural terms, the above object, starting from a method of the type described above, achieved in that on the clipboard from the cut slices a shingled disc assembly is generated, wherein the clipboard is moved transversely to the feed direction. The portion is thereby transferred in an unfinished state of the clipboard to the conveyor, wherein the transferred portion after it has been taken over by the conveyor, completed by cutting and adding at least one other disc and then discharged. The method according to the invention thus combines the temporal advantages, ie the high cutting performance, with the use of a clipboard, on which the panes are temporarily arranged, with the optical attractiveness of a shingled pane arrangement. Under a shingled disc arrangement in the context of the present application, all possible storage images are to be understood, in which the discs do not form a vertically aligned stack of discs with always aligned disc edges. With a shingle in the context of this application is thus also a fan, a shingled arrangement or a partially meandering storage the same disc to understand, so that a total of air trapped and therefore voluminous disc portion is generated, which is practiced especially in wafer-thin slices to later to facilitate their separation from each other.
Die Erzeugung einer fertigen Portion erfolgt somit in zwei Phasen, nämlich einer Phase, in der (zunächst) die Zwischenablage als Stützorgan für die im Entstehen begriffene Portion dient. Nach einer gewissen Zeit, das heißt der Erzeugung einer gewissen Anzahl von Scheiben der aktuell im Entstehen begriffenen Portion, wird diese bei laufendem Schneidvorgang, das heißt, insbesondere auch bei unverändert fortgesetztem Vorschub und unveränderter Rotation des Messers auf die Fördereinrichtung übergeben, was deshalb unkritisch ist, weil die Ablage, das heißt Hinzufügung weiterer Scheiben auf der Oberseite der Portion erfolgt, wohingegen der Wechsel in der Abstützung von der Zwischenablage zu der Fördereinrichtung auf der Unterseite stattfindet und daher so gestaltet werden kann, dass er keinerlei Störungen auf der Oberseite der entstehenden Portion bewirkt.The production of a finished portion thus takes place in two phases, namely a phase in which (initially) the clipboard serves as a support member for the portion which is being formed. After a certain time, that is to say the generation of a certain number of slices of the portion which is currently being formed, it is transferred to the conveyor during the cutting process, that is to say, in particular also with the feed continued and the rotation of the knife unchanged, which is therefore uncritical because the deposit, that is to say the addition of further slices, takes place on the upper side of the portion, whereas the change in support from the clipboard to the conveyor takes place on the underside and therefore can be made such that it does not interfere with the top of the resulting portion causes.
Folglich wird der apparative Aufwand ebenso reduziert, wie die Anforderungen an die Steuerung, da im Vergleich mit der
Das erfindungsgemäße Verfahren kommt vorzugsweise mit einer einzigen Zwischenablage aus und eine Mehrzahl von Scheiben, d.h. eine Teilportion, wird gemeinsam, d.h. alle Scheiben mehr oder weniger gleichzeitig und zusammenhängend von der Zwischenablage unmittelbar, d.h. ohne Zwischenschaltung eines aus der
Eine besonders einfache Übergabe abgeschnittener Scheiben von der Zwischenablage auf die Fördereinrichtung wird dann ermöglicht, wenn Tragelemente der Zwischenablage bei der Übergabe in Zwischenräume zwischen benachbarten Riemchen der Fördereinrichtung eintreten, wobei eine die Scheiben abstützende Oberfläche der Tragelemente nach der Übergabe unterhalb einer die Scheiben tragenden Oberfläche der Riemchen der Fördereinrichtung angeordnet ist. Durch das vorgenannte Eintauchen findet ein Wechsel der Abstützung der Scheiben von der Zwischenablage auf die Fördereinrichtung statt.A particularly simple transfer of cut slices from the clipboard to the conveyor is then enabled when support elements of the clipboard enter into spaces between adjacent straps of the conveyor during transfer, with a disc supporting surface of the support elements after transfer below a disc carrying surface of the Riemchen the conveyor is arranged. By the aforementioned immersion takes place a change of the support of the discs from the clipboard to the conveyor.
Die Erfindung weiter ausgestaltend wird vorgeschlagen, dass die Zwischenablage eine aus translatorischen Bewegungsabschnitten zusammengesetzte Bewegung entlang einer in sich geschlossenen Bahnkurve ausführt, wobei sie
- ausgehend von einer Wartestellung, in der sie sich außerhalb einer Projektion des Querschnitts des Lebensmittelstrangs in eine zu einer Längsachse des Lebensmittelstrangs senkrechten und die Oberfläche der Tragelemente enthaltenen Ebene befindet,
- im Wesentlichen parallel zu der vorgenannten Ebene in eine erste Aufnahmestellung bewegt wird, in der eine erste Scheibe einer neuen Portion aufgenommen wird,
- anschließend sukzessiv in nachfolgende Aufnahmestellungen bewegt wird, in denen sie zu Erzeugung des jeweils gewünschten Ablagebildes der Scheiben und zur Aufnahme der jeweils folgenden Scheibe gegenüber der vorangegangenen Aufnahmestellung in Vorschubrichtung des Lebensmittelstrangs und/oder senkrecht zu der Vorschubrichtung des Lebensmittelstrangs verschoben ist,
- nach Aufnahme einer vorbestimmten Zahl von Scheiben eine Entleerungsstellung einnimmt, in der die Zwischenablage und die Fördereinrichtung sich, in Vorschubrichtung betrachtet, relativ zueinander soweit bewegt haben, dass die Scheiben den Kontakt zu der Oberfläche der Tragelemente verloren haben und stattdessen in Kontakt mit der Oberfläche der Riemchen der Fördereinrichtung getreten sind,
- und schließlich wieder in die Wartestellung überführt wird, ohne dabei mit den Tragelementen die Ebene der Oberfläche der Riemchen der Fördereinrichtung im Bereich der Riemchen zu berühren.
- starting from a waiting position in which it is located outside a projection of the cross section of the food strand into a plane perpendicular to a longitudinal axis of the food strand and containing the surface of the supporting elements,
- is moved substantially parallel to the aforementioned level in a first receiving position in which a first slice of a new portion is taken,
- is then successively moved to subsequent receiving positions, in which they produce the respective desired storage image of the slices and is displaced in the feed direction of the food strand and / or perpendicular to the advancing direction of the food strand for receiving the respective following slice relative to the preceding receiving position,
- after receiving a predetermined number of slices occupies a discharge position in which the clipboard and the conveyor, viewed in the feed direction, relative to each other have moved so far that the discs have lost contact with the surface of the support elements and instead in contact with the surface of the Straps of the conveyor are stepped,
- and finally transferred back to the waiting position, without touching with the support elements, the level of the surface of the belt of the conveyor in the region of the straps.
Die Übergabe abgeschnittener Scheiben von der Zwischenablage auf das Förderband lässt sich vorteilhafterweise im Wege einer in Vorschubrichtung verlaufenden Relativbewegung zwischen der Zwischenablage und der Fördereinrichtung erzielen. Dabei kann bei stillstehender Fördereinrichtung die Zwischenablage entsprechend weit abgesenkt werden oder aber bei stillstehender Zwischenablage die Fördereinrichtung in Vorschubrichtung aufwärts auf den Lebensmittelstrang zu bewegt werden. Auch eine Kombination der beiden vorgenannten Bewegungsarten ist möglich, wobei sich dann - mit Bezug auf ein stillstehendes Maschinengestell - die Zwischenablage und die Fördereinrichtung in vertikale Richtung aufeinander zu bewegen.The transfer of cut slices from the clipboard onto the conveyor belt can advantageously be achieved by means of a relative movement between the clipboard and the conveyor running in the feed direction. In this case, when the conveyor is stationary, the clipboard can be lowered correspondingly far or else, when the clipboard is stationary, the conveyor can be moved upwards in the feed direction toward the food strand. A combination of the two aforementioned types of movement is possible, in which case - with respect to a stationary machine frame - to move the clipboard and the conveyor in the vertical direction to each other.
Während des Schneidbetriebs wird bei der Erzeugung einfacher vertikaler (ungeschindelter) Scheibenstapel (was bei einer erfindungsgemäßen Vorrichtung gleichwohl möglich ist) die Fördereinrichtung (bzw. zuvor auch die Zwischenablage) mit jeder neu hinzukommenden Scheibe sukzessiv um das Dickenmaß der Scheibe abgesenkt, um während des gesamten Schneidvorgangs einen konstanten Abstand zwischen der Schnittebene des Messers und der Ablagefläche für die neu entstehende Scheibe (in Form der Oberfläche der Zwischenablage oder der Oberfläche der letzten bereits abgeschnittenen Scheibe) zu erreichen. Eine derartige Absenkung ist auch bei der erfindungsgemäßen Schindelerzeugung auf der Zwischenablage möglich und insbesondere bei Schindeln mit größerer Dicke (in Vorschubrichtung betrachtet) sinnvoll.During the cutting operation, in the production of simple vertical (ungeschindelter) stack of discs (which is nevertheless possible in a device according to the invention), the conveyor (or previously also the clipboard) with each newly added disc successively lowered by the thickness of the disc to throughout the Cutting process to achieve a constant distance between the cutting plane of the knife and the shelf for the emerging disc (in the form of the surface of the clipboard or the surface of the last already cut disc). Such a reduction is also in the shingle production according to the invention on the clipboard possible and especially for shingles with greater thickness (viewed in the feed direction) makes sense.
Um im Moment der Aktivierung der Zwischenablage zur Aufnahme der ersten Scheibe einer neuen Portion ein rasches "Einschießen" der Zwischenablage zu ermöglichen, ist es sinnvoll, dass sich diese in ihrer Wartestellung mit der Oberfläche ihrer Tragelemente in der selben Ebene befindet, wie die dem Lebensmittelstrang zugewandte Oberfläche der letzten vollständig abgeschnittenen Scheibe auf der Fördereinrichtung. Bei fortgesetztem Absenken der Fördereinrichtung (kontinuierlich oder schrittweise) wird sodann im nächsten Moment gerade soviel vertikaler Raum oberhalb der bereits abgeschnittenen und etwas weiter abgesenkten Scheiben erzeugt, dass die Zwischenablage quer zur Vorschubeinrichtung in den Strangquerschnitt eingeführt werden kann.In order to enable a rapid "shooting in" of the clipboard at the moment of activating the clipboard for receiving the first slice of a new portion, it makes sense that it is in its waiting position with the surface of its support elements in the same plane as that of the food strand facing surface of the last completely cut disc on the conveyor. With continued lowering of the conveyor (continuously or stepwise) is then generated in the next moment just as much vertical space above the already cut and slightly further lowered discs that the clipboard can be introduced transversely to the feed device in the strand cross-section.
Um hinreichend Zeit zum "Einschießen" der Zwischenablage in den Strangquerschnitt zu besitzen, kann die Zwischenablage die Wartestellung erst dann verlassen, wenn das Messer bereits mit dem Abschneiden einer nächsten Scheibe begonnen hat und sich bereits innerhalb des Querschnitts des Lebensmittelstrangs befindet. Bei besonders kritischen zeitlichen Verhältnissen, d. h. bei einer hohen Schneidfrequenz und entsprechend hohen Schneidleistung, kann die Zwischenablage bei ihrer Bewegung in eine Projektion des Querschnitts des Lebensmittelstrangs in eine zu der Vorschubrichtung senkrechte Ebene sogar einen bereits durch die Schwerkraft bedingt herabhängenden oder gar auf der zuvor abgeschnittenen Scheibe aufliegenden Teil der aktuell im Entstehen begriffenen Scheibe mit der Oberfläche ihrer Tragelemente wieder anheben. Auf diese Weise wird eine sich bereits anbahnende Ablage der neuentstehenden Scheibe auf den Scheiben der vorangegangenen Portion durch das Überführen der Zwischenablage in die Aufnahmestellung wieder rückgängig gemacht, um die aktuell entstehende Scheibe der neuen Portion, das heißt der Zwischenablage, zuzuordnen. Wichtig ist es in diesem Zusammenhang, dass das Messer einerseits und die Zwischenablage andererseits von entgegen gesetzten Seiten her in den Querschnitt des Lebensmittelstrangs eintreten.In order to have sufficient time to "shoot in" the clipboard into the strand cross-section, the clipboard can not leave the wait position until the knife has already begun to cut a next slice and is already within the cross-section of the food strand. For particularly critical temporal conditions, d. H. At a high cutting frequency and correspondingly high cutting performance, the clipboard can move in a projection of the cross section of the food strand in a direction perpendicular to the feed direction even an already suspended by gravity or even resting on the previously cut slice part of the currently emerging Raised disc with the surface of their support elements again. In this way, an already imposing storage of the new disc on the discs of the previous portion by the transfer of the clipboard in the receiving position is reversed again to assign the currently emerging disc of the new portion, ie the clipboard. It is important in this context that the knife on the one hand and the clipboard on the other hand enter from opposite sides in the cross section of the food strand.
In vorrichtungstechnischer Hinsicht wird die zugrunde liegende Aufgabe dadurch gelöst, dass die Zwischenablage so quer zur Vorschubrichtung des Lebensmittelstrangs bewegbar ist, dass auf ihr eine zumindest abschnittsweise linear geschindelte Scheibenanordnung erzeugbar ist und die Zwischenablage die Form einer Gabel aufweist, die aus einer Vielzahl paralleler Tragelemente gebildet ist, die in Zwischenräume zwischen benachbarten Riemchen der Fördereinrichtung eintreten, um die Portion in einem unvollendeten Zustand von der Zwischenablage an die Fördereinrichtung übergeben zu können, wobei die übergebene Portion, nachdem sie von der Fördereinrichtung übernommen wurde, durch Abschneiden und Hinzufügen mindestens einer weiteren Scheibe vollendet und anschließend ausgetragen wird.In device-technical terms, the underlying object is achieved in that the clipboard is movable transversely to the feed direction of the food strand that on her at least partially linearly shingled disc assembly can be generated and the clipboard has the shape of a fork, which formed from a plurality of parallel support elements is that in spaces between adjacent straps enter the conveyor to transfer the portion in an unfinished state from the clipboard to the conveyor, wherein the transferred portion, after it has been taken over by the conveyor, completed by cutting and adding at least one other disc and then discharged.
Dies ist bei den bekannten Vorrichtungen entweder wegen eines Mangels an hinreichender Fläche auf der Zwischablage oder wegen nicht gegebener Bewegungsmöglichkeit nicht realisierbar. Vorzugsweise ist die Zwischenablage von einer Aufnahmestellung, in der von ihr die erste Scheibe einer neuen Portion aufnehmbar ist, im Zuge der Erzeugung einer geschindelten Scheibenablage sukzessive weiter von einer Wartestellung entfernbar, in der sie sich vollständig außerhalb einer Projektion des Querschnitts des Lebensmittelstrangs in eine zu der Schneidebene parallele Ebene befindet.This is not feasible in the known devices, either because of a lack of sufficient area on the intermediate tray or because of non-given possibility of movement. Preferably, the clipboard from a receiving position in which it is the first slice of a new portion can be removed in the course of generating a shingled disc tray successively removable from a waiting position in which they are completely outside a projection of the cross section of the food strand in a the cutting plane is parallel plane.
Die erfindungsgemäße Vorrichtung bedingt in diesem Fall zwar einen gegenüber dem Bewegungszyklus, wie er zum bloßen zwischenzeitlichen Aufnehmen vertikaler Scheibenstapel nötig ist, eine Erweiterung der Bewegungsmöglichkeit der Zwischenablage in die Richtung, in die die vollendete Portion später typischerweise ausgetragen wird, und zwar unter Verwendung der Fördereinrichtung. Jedoch erlaubt die erfindungsgemäße Vorrichtung eine besonders hohe Schneidleistung, da der Einschießweg (Strecke zwischen der Warteposition und der Aufnahmeposition) minimiert wird und das spätere sukzessive Weiterbewegen der Zwischenablage in dieselbe Richtung wie der Einschießvorgang erfolgt, jedoch mit entsprechender zeitlicher Verzögerung - entsprechend dem Anfall der folgenden Scheiben - stattfinden kann. Bei der alternativen Vorgehensweise, bei der der Einschießweg vergrößert wäre und beim folgenden Aufbau des Schindels bereits wieder eine Umkehr der Bewegungsrichtung stattfindet, ist nachteiliger Weise bei gleicher Einschießgeschwindigkeit der Zeitbedarf bei der Zwischenablage zum Erreichen der Auffangposition (entsprechend des verlängerten Weges) größer.Although the device according to the invention in this case requires an extension of the possibility of movement of the clipboard in the direction in which the finished portion is later typically discharged, as compared to the cycle of movement required for the mere interim picking up of vertical slice stacks, using the conveyor means , However, the inventive device allows a particularly high cutting performance, as the Einschießweg (distance between the waiting position and the receiving position) is minimized and the subsequent successive movement of the clipboard in the same direction as the Einschießvorgang done, but with a corresponding time delay - corresponding to the attack of the following Slices - can take place. In the alternative approach, in which the Einschießweg would be increased and the next construction of the shingles again reversing the direction of movement takes place, disadvantageously, at the same Einschießgeschwindigkeit the time required for the clipboard to reach the collection position (corresponding to the extended path) greater.
Die erfindungsgemäße Vorrichtung realisiert somit im Anschluss an das Einschießen keine Umkehr der Bewegungsrichtung der Zwischenablage während des Vorgangs des anschließenden Schindelns. Die Bewegungsumkehr findet erst statt, wenn nach Übergabe einer Teilportion von der Zwischenablage auf die Fördereinrichtung die Zwischenablage wieder aus dem Strangquerschnitt herausbewegt werden muss, wobei der dann verlängerte Weg (gegenüber einem Verfahren mit Bewegungsumkehr unmittelbar im Anschluss an das Erreichen der Aufnahmeposition) unkritisch ist, weil bis zur Vollendung der jeweiligen Portion noch hinreichend Zeit zur Verfügung steht, um die Zwischenablage in die Wartestellung zurück zu überführen.The device according to the invention thus implements no reversal of the direction of movement of the clipboard during the operation of the subsequent shingling following the insertion. The reversal of motion takes place only when after transfer of a partial portion of the clipboard on the conveyor, the clipboard must be moved back out of the strand cross-section, the then extended path (compared to a method with reversal of motion immediately following the Reaching the recording position) is uncritical, because until the completion of each portion still sufficient time is available to transfer the clipboard back to the waiting position.
Gemäß einer Ausgestaltung der erfindungsgemäßen Vorrichtung sind eine Mehrzahl abgeschnittener Scheiben gemeinsam von der Zwischenablage unmittelbar auf die Fördereinrichtung übergebbar. Der Vorteil liegt hier wiederum in der Möglichkeit des Verzichts auf ein separates Übergabeelement, wie dies in der
Eine Weiterbildung der erfindungsgemäßen Vorrichtung besteht darin, dass die Zwischenablage Tragelemente besitzt, die so angeordnet sind, dass sie in Zwischenräumen zwibenachbarten Riemchen der Fördereinrichtung positionierbar sind, wobei eine durch die Oberfläche der Tragelemente definierte Ebene parallel zu einer durch die Oberfläche der Riemchen der Fördereinrichtung definierte Ebene verläuft. Durch die Parallelität der vorgenannten Ebenen wird die Übergabe der Scheiben von der Zwischenablage auf die Riemchen besonders schonend gestaltet, wodurch eine sehr hohe Qualität der Ablagegeometrie erzielt wird. Vorzugsweise ist die Zwischenablage gabelförmig gestaltet und die Tragelemente sind zinkenförmig ausgebildet und an einem Tragbalken angeordnet, vorzugsweise damit verschweißt.A further development of the device according to the invention is that the clipboard has supporting elements which are arranged so that they intersect in intermediate spaces Straps of the conveyor can be positioned, wherein a plane defined by the surface of the support elements extends parallel to a plane defined by the surface of the straps of the conveyor plane. Due to the parallelism of the aforementioned levels, the transfer of the disks from the clipboard to the aprons is made particularly gentle, whereby a very high quality of the filing geometry is achieved. Preferably, the clipboard is fork-shaped and the support members are tine-shaped and arranged on a support beam, preferably welded thereto.
Um eine hohe Dynamik bei der Bewegung der Zwischenablage zu ermöglichen, sollte die Masse der stark zu beschleunigenden Zwischenablage möglichst gering gehalten werden. Dies gilt insbesondere deshalb, weil die Zwischenablage bedingt durch die Schindelablage deutlich größer (länger und/oder breiter) sein muss, als bei der bloßen Stapelbildung. Aus diesem Grunde sollte die in Vorschubrichtung gemessene Höhe der Tragelemente kleiner als die doppelte, vorzugsweise kleiner als die 1,5-fache, Dicke der abzuschneidenden Scheiben sein, insbesondere kleiner als 10 mm, vorzugsweise als 8 mm, weiter vorzugsweise zwischen 4 mm und 6 mm liegen. Die Masse der Zwischenablage sollte weiniger als 0,5 kg, vorzugsweise kleiner als 0,3 kg betragen. Als Werkstoff für die Zwischenablage, insbesondere der Tragelemente kommt neben Edelstahl oder Leichtmetall-Legierungen auch faserverstärkter Kunststoff, insbesondere unter Verwendung von Karbonfasern, in Frage.In order to allow a high dynamic in the movement of the clipboard, the mass of the strong to be accelerated clipboard should be kept as low as possible. This is especially true because the clipboard due to the shingled shelf must be significantly larger (longer and / or wider), as in the mere stacking. For this reason, the measured in the feed direction height of the support elements should be smaller than twice, preferably less than 1.5 times, the thickness of the slices to be cut, in particular less than 10 mm, preferably 8 mm, more preferably between 4 mm and 6 mm lie. The mass of the clipboard should be less than 0.5 kg, preferably less than 0.3 kg. As a material for the clipboard, in particular the support elements comes next to stainless steel or light metal alloys and fiber-reinforced plastic, in particular using carbon fibers, in question.
In konstruktiver Hinsicht ist es von Vorteil, wenn die Zwischenablage in einem Auffangrahmen senkrecht zu der Vorschubrichtung verschiebbar gelagert ist und der Auffangrahmen an ein Maschinengestell in Vorschubrichtung verschiebbar gelagert ist, wobei der Auffangrahmen zwei seitlich neben der Fördereinrichtung angeordnete Linearführungen für die Zwischenablage aufweist. Unter Auffangrahmen im Sinne der vorliegenden Anmeldung ist dabei nicht zwingend eine in sich geschlossene Ausführung von Streben zu verstehen. Vielmehr ist insbesondere auch eine dreiseitig, d. h. U-förmige Anordnung von Streben damit gemeint, was sinnvoll ist, um Lagereinrichtungen für die Zwischenablage zu beiden Seiten neben der Fördereinrichtung realisieren zu können. Bei den Linearführungen kommt insbesondere auch ein Antrieb mit Hilfe eines Synchronriemens in Frage, der sich durch einen schlupffreien Lauf auch bei größter Dynamik der Bewegung auszeichnet.In constructive terms, it is advantageous if the clipboard is mounted displaceably in a catch frame perpendicular to the feed direction and the catch frame is slidably mounted on a machine frame in the feed direction, wherein the catch frame has two laterally arranged next to the conveyor linear guides for the clipboard. Under catch frame in the sense of the present application is not necessarily a self-contained execution of struts to understand. Rather, in particular, a three-sided, ie U-shaped arrangement of struts meant, which makes sense to realize storage facilities for the clipboard on both sides next to the conveyor can. In the linear guides in particular, a drive with the help of a timing belt in question, which is characterized by a slip-free running even at maximum dynamics of movement.
Typischerweise wird die Fördereinrichtung von einer gleichfalls in Form eines Bandes mit einer Mehrzahl parallel zueinander verlaufender Riemchen gebildeten Austrageeinrichtung gefolgt. Um bei einer Verschiebung der Fördereinrichtung, insbesondere auch deren der Austrageeinrichtung zugewandten Seite, einen stetigen Übergang zwischen Fördereinrichtung und Austrageeinrichtung gewährleisten zu können, kann die Fördereinrichtung gemeinsam mit der Austrageeinrichtung an einem Austragerahmen gelagert sein, welcher wiederum an einem Maschinengestell verstellbar, insbesondere verschiebbar und/oder schwenkbar gelagert ist.Typically, the conveyor is followed by a likewise formed in the form of a belt having a plurality of mutually parallel straps discharge device. In order to ensure a steady transition between conveyor and discharge device during a displacement of the conveyor, in particular also the Austrageeinrichtung side, the conveyor may be stored together with the discharge on a discharge frame, which in turn adjustable on a machine frame, in particular slidably and / or is pivotally mounted.
Um auf der Zwischenablage hinreichend Platz auch für eine Erzeugung langgestreckter Schindel (Teilportion) vor ihrer Übergabe auf die Fördereinrichtung realisieren zu können, sollten die Tragelemente der Zwischenablage eine senkrecht zur Vorschubrichtung gemessene Länge besitzen, die mindestens der doppelten, vorzugsweise mindestens der dreifachen, senkrecht zur Vorschubrichtung gemessenen Breite der abgeschnittenen Scheiben entspricht.In order to be able to realize sufficient space on the clipboard for production of elongate shingles (partial portion) prior to their transfer to the conveyor, the support elements of the clipboard should have a length measured perpendicular to the feed direction, at least twice, preferably at least three times, perpendicular to Feed direction measured width of the cut slices corresponds.
Um in der häufig zeitkritischen Phase des "Einschießens" der Zwischenablage zeitliche Probleme zu vermeiden, sollte die Zwischenablage - ausgehend von ihrer Wartestellung - in die selbe Richtung in eine Projektion des Querschnitts des Lebensmittelstrangs in eine Ebene, die von den Tragelementen der Zwischenablage gebildet ist, einführbar sein, wie die abgeschnittenen Scheiben von der Fördereinrichtung abführbar sind.In order to avoid temporal problems in the often time-critical phase of "putting in" of the clipboard, the clipboard should - starting from its waiting position - in the same direction in a projection of the cross section of the food strand in a plane formed by the support elements of the clipboard, be introduced, as the cut slices are discharged from the conveyor.
Dem gleichen Zweck einer zeitlichen Entspannung des Schneidvorgangs dient die Maßnahme, wonach die Zwischenablage von einer Seite her in eine Projektion des Querschnitts des Lebensmittelstrangs in eine Ebene, die durch die Oberfläche der Tragelemente der Zwischenablage gebildet ist, eintritt, die einer Seite gegenüberliegt, an der sich eine im Entstehen befindliche Scheibe durch die Schwerkraft bedingt von dem Lebensmittelstrang ablöst.The same purpose of a relaxation of the cutting operation is the measure, according to which the clipboard enters from one side into a projection of the cross section of the food strand in a plane formed by the surface of the support elements of the clipboard, which is opposite to a side on the Due to gravity, an emerging disc will detach from the food strand due to gravity.

Eine in den
Auf einer dem Lebensmittelstrang 2 und der Vorschubeinrichtung 10 abgewandten Seite der Schneidebene 7 befinden sich nebeneinander und einander teilweise überlappend eine Austrageeinrichtung 13, eine Fördereinrichtung 14 und eine Zwischenablage 15. Die Zwischenablage 15 besitzt die Form einer Gabel und weist eine Vielzahl parallel und äquidistant zueinander angeordneter zinkenförmiger Tragelemente 16 und einen senkrecht zu den Tragelementen verlaufenden und mit letzteren verbundenen Tragbalken 17 auf. Die Zwischenablage 15 ist in einem Auffangrahmen 18 gelagert und zwar so, dass sie senkrecht zu der Vorschubrichtung, das heißt parallel zu der Schneidebene 7 verschiebbar ist. Hierzu ist der Tragbalken 17 an beiden Längsenden in jeweils einer Linearführung 19 gelagert, die sich jeweils im Inneren einer Längsstrebe 20 des Auffangrahmens 18 befindet. Der Antrieb der Zwischenablage 15 in Richtung der Linearführungen 19 erfolgt mit Hilfe jeweils eines Synchronriemens 21, der beidseitig der Zwischenablage 15 mittels eines Kopplungselements mit dem Tragbalken 17 verbunden ist.On a side facing away from the

Die Fördereinrichtung 14 enthält eine Vielzahl von äquidistant zueinander angeordnete und auf ihrer Oberseite eine gemeinsame Förderebene 28 bildenden Riemchen 29, die um zwei Ringnuten für die Riemchen 29 aufweisende Umlenkwalzen 30, 31, von denen eine mittels eines Servoantriebs antreibbar ist, geführt sind. Der lichte Abstand zwischen benachbarten Riemchen 29 ist geringfügig größer als die senkrecht zur Längserstreckung der gabelförmigen Tragelemente 16 gemessenen Breite der Tragelemente 16. Da das Teilungsmaß der Riemchen 29 der Fördereinrichtung 14 dem Teilungsmaß der Tragelemente 16 der Zwischenablage 15 entspricht, kann letztere daher in die Zwischenräume zwischen benachbarten Riemchen eintauchen, was für die weiter unten beschriebene Übergabe abgeschnittener Scheiben von der Zwischenablage 15 auf die Fördereinrichtung 14 entscheidend ist.The
Die Austrageeinrichtung 13 umfasst ebenso wie die Fördereinrichtung 14 eine Mehrzahl von Riemchen 32, deren Breite jedoch erheblich größer ist als die der Riemchen 29 der Fördereinrichtung 14. Eine Umlenkwalze 33 der Austrageeinrichtung 13 ist so nah an der Umlenkwalze 30 der Fördereinrichtung 14 angeordnet, dass die Riemchen 29, 32 nicht miteinander kollidieren, wobei eine störungsfreie und die Scheibenanordnung nicht beeinträchtigende Übergabe von der Fördereinrichtung 14 auf die Austrageeinrichtung 13 sichergestellt ist.The
Die Austrageeinrichtung 13 ist in einem Austragerahmen 34 gelagert, welcher um die Drehachse einer Umlenkwalze 35 schwenkbar in dem Maschinengestell 23 gelagert ist. Das der Umlenkwalze 33 der Austrageeinrichtung 13 zugeordnete Ende der Austrageeinrichtung 13, ist mit einem in

Sobald die letzte vollendete Portion hinreichend weit aus dem sich keilförmig verjüngenden Spaltbereich zwischen dem Messer 5 und der Oberfläche der Austrageeinrichtung 13 entfernt hat, kann die Fördereinrichtung 14 mit der daran gekoppelten Umlenkwalze 33 der Austrageeinrichtung 13 wieder in Vorschubrichtung nach oben bewegt werden. Auf diese Weise, d.h. aufgrund der Relativbewegung zwischen Fördereinrichtung 14 und Zwischenablage 15, kann die Zwischenablage 15 außer Funktion gesetzt werden, indem die Oberfläche der Riemchen 29 mindestens so hoch angeordnet ist wie die Oberfläche der Tragelemente 16 der Zwischenablage 15.
