EP2359992B2 - Machine for cutting elongated food - Google Patents

Description

The invention relates to the use of a machine for cutting a rope-shaped food in slices, the machine comprising a feed area, a cutting device and a removal area, wherein a food strand in the feed direction from the feed area by means of a feed device to the cutting device is vorschiebbar, the one rotationally a housing-fixed first rotation axis revolving rocker and a circular axis rotatably mounted about a second axis of rotation circular blade can be cut off from the food strand on the front successive slices, which can be transferred after their separation from the food strand in the removal area, the feed direction is approximately horizontal ,

Under approximately horizontal feed direction in the context of the present application deviations from a horizontal of max. 10 ° to be understood.

A machine of the aforementioned kind was already produced and marketed in the 1980s as a ROK chop cutting machine by Berkel Deutschland GmbH. In order to keep the footprint of the machine small and in particular to work with a small diameter of the circular blade, the drive within the rocker is covered with a wedge-shaped cover. This ensures that the circular blade can pass with its axis of rotation and part of the cover through the cross section of the food strand, since the slanted wedge shape of the rocker housing, the emerging discs forward, i. in the feed direction, be pushed.

In particular, when cutting bone-containing foods such. As chops, the known machine has proved problematic. When the discs are separated, a formation of bone splinters regularly occurs which adhere to the separated discs and lead to a negative assessment of the cutting quality. In particular, in a subsequent to the disc production packaging of the cut food to SB-portion units can be a possible fragmentation neither control nor subsequently remove any splinters.

A basically similar in some way similar machine is in each case of the bread slicer according to the DE-A 103 12 301 and the EP-A 1 520 666 educated. Again, the swingarm of the orbital circular knife is covered with a flat, wedge-shaped cover. However, the wedge action of the rocker when passing through the bread cross-section leads only to an elastic pushing away the emerging disc and is not in relation to the cutting result of disadvantage. Rather, in bread slicing machines, it is often important to maintain a small footprint, as it is common to set up such machines in bakery shops where typically only limited space is available.

Circular knives with Orbitelantrieb also find in the genus of so-called slicer use, with which boneless sliced products such as sausage, ham, cheese, or the like. In thin slices of about 0.5 mm to 2 mm are cut. The food strand is thereby advanced either vertically or obliquely (with about 30 ° to 60 ° to the horizontal) hanging on the cutter.

task

The invention has for its object to improve the quality of cutting when cutting frozen or frozen, bone-containing meat.

solution

The underlying object is achieved by the use according to claim 1.

In the use according to the invention, when portion cutting is dispensed with, the axis of rotation of the circular blade and thus also a part of the rocker are guided through the cross section of the food strand. This results in the need to select circular knives with a large diameter, because in principle less than half of the diameter is available to the maximum cutting cross-section, that is, in one revolution of the rocker. to cover a conveyor cross section that is structurally available in the feed area. The rocker thus moves in the machine according to the invention always outside the cutting cross-section and therefore can not exert any negative effect on the cutting process, i. in particular not to exert a "blunt pressure load" in the gap region between the already separated part of the disc and the remainder of the food strand.

It has been found that with the invention. Use bone-chopped, frozen and frozen food strands in excellent cutting quality cut into portions. In particular, the fragmentation of bone, as was unavoidable in the known chop cutting machine mentioned at the outset, is excluded with great certainty. The pane thickness is between 5 mm and 30 mm in the case of the use according to the invention.

The first axis of rotation about which the rocker rotates is arranged at a distance laterally adjacent to a straight line which laterally delimits the maximum cutting cross section. The direction of rotation of the rocker rotation is to be chosen so that the circular blade (obliquely) enters from above into the cutting cross section, which always achieves a sufficiently large contact pressure of the food strand on the counter cutting of the feed area or a diagonally opposite lower corner region of the cutting cross section and lifting of the food strand is reliably avoided by a footprint of the feed area.

The cutting result is further particularly positively influenced when a horizontally extending counter-blade of the feed area and an opposite horizontal counter-blade of the removal area are approximately at the same height. The support of the forces resulting in the cutting, in particular of bone-containing foods, is particularly advantageous in the case of such an arrangement of the two counter-cutting edges. The gap area between the opposing counter-blades exceeds the thickness of the circular blade only so far (typically in tenths of a millimeter range), as required for a non-contact passage of the circular blade.

According to one embodiment of the invention it is provided that the rocker on the one hand and the circular blade on the other hand each be driven by means of a separate drive motor.

This has the advantage that in particular the ratio of the rotational speed of the circular blade to the rotational speed of the rocker is very easily changeable. At least one of the two drives should be equipped with a frequency converter for speed control. In principle, however, it is also within the scope of the invention if both the rocker and the circular blade are driven by the same drive, resulting in a fixed speed ratio of rocker and circular blade.

In order to obtain a particularly good cutting result, in particular a real sawing effect by the circular blade, the ratio of the rotational speed of the circular blade to the rotational speed of the rocker for on or frozen bone-containing food to at least 6: 1, preferably at least 8: 1, is selected. To avoid smearing of the food, a lower ratio should be chosen for non-frozen foods than for frozen or frozen foods, where as high as possible a circular blade speed should be achieved, as with a "circular saw".

It is particularly advantageous if the circular blade has a thickness of less than 10 mm, preferably less than 8 mm, more preferably less than 6 mm. As the thickness of the knife decreases, the wedge effect on the food and also the force required for the cutting process is reduced. In particular, this also reduces the risk of splinters being produced when a bone is severed. In addition, the circular blade diameter should be at least 500 mm, preferably at least 600 mm, more preferably at least 700 mm.

In order to reduce the friction between the knife and the food during the cutting process, a circular knife can be provided according to the invention, which is undercut on both sides in a longitudinal section following a wedge area. This avoids that the circular blade in the undercut, i. reduced in thickness region, comes into contact both with the face of the remaining food strand and with the side surface of the nascent disk. As a result, the side forces are reduced to the nascent disk and the geometry of the portions produced improves, which is particularly important in terms of the goal of weight-accurate generation of portions of importance.

In the removal area of the machine, a conveyor belt should preferably be arranged which connects as directly as possible to a cutting frame arranged in the removal area and forming a counter-cutting edge. In this way, an orderly and efficient removal of the cut slices ensure that high cutting performance can be achieved with the machine according to the invention. An automatic packaging device can be connected to the removal conveyor belt.

The invention further ausgestaltend it is proposed that a cutting frame of the feed area and / or a cutting frame of the removal area of an integrally formed body and one ends of two U-legs of the main part connecting vertical and the first axis of rotation facing connecting leg is composed or are. In such an embodiment, in particular, the lower corner region between the counter-blade and the vertical connecting leg of the U-shaped main part is formed integrally and solidly to accommodate the occurring in this area large supporting forces during the cutting operation safely and deformation-free. By contrast, the connecting arm facing the rocker, which closes the U to form a rectangular frame, can be made very thin, so that the rocker can be brought as close as possible to the cutting cross-section defined by the free space within the cutting frame. This in turn can be realized with the smallest possible diameter of the circular blade as large as possible cutting cross-section.

In addition, in the inventive use is still provided that a counter-blade of the removal area, preferably a cutting frame of the removal area on which the counter-blade the removal area is formed, with a counter-blade of the feed area, preferably with a cutting frame of the feed area, on which the counter-blade of the feed area is formed, is firmly connected. Preferably, the counter-cutting of the removal area or the cutting frame containing them is fixedly connected to a machine frame, wherein the removal conveyor is attached to the opposite of a cutting box door which is pivotally mounted about a vertical axis on the machine frame or the feed area. As a result, a composite of the two counter cutting edges or cutting frame is achieved, which is important for a secure support occurring during cutting operation in the vertical direction or obliquely downward counter-forces. In particular, there is no need in this case for the hinged suspension of a cutting box door to be made so solid that it can divert the opposing forces which occur on the side of the removal area into the machine frame, which would then be necessary if the counter-blade located on the side of the removal area the local cutting frame would be attached to the cutting box door. According to the invention, therefore, a very stable and simple construction of the counter-cutting edges is combined with the advantage of good accessibility of this area, in which the cutting-board door with the removal conveyor attached thereto is opened.

Finally, the cutting frame of the removal area should be formed ramp-shaped at its horizontal leg in cross-section, wherein a side facing away from the cutting device of the leg of the counter-cutting edge, starting in the feed direction drops down. The angle of the ramp should be about 30 ° to 60 ° with respect to the horizontal.

The invention will be explained in more detail with reference to an embodiment of a cutting machine, which is shown in the drawing.

A known in terms of their basic structure of the prior art machine 1 has a particular in the FIGS. 8 to 10 recognizable feed area 2, one in the FIGS. 1 to 7 illustrated cutting device 3 and one best in the FIGS. 1 to 6 recognizable transport area 4 for cut slices (portions) on. The cutting device 3 has a rocker 6 mounted rotatably driveable within a machine housing 5, which rotates in the cutting operation about horizontally oriented and parallel to a feed direction axis of rotation 7. On the rocker 6 is located at a distance 8 from the axis of rotation 7, a rotation axis 9 about which a circular blade 10 rotates, the in FIG. 1 not, but in the FIGS. 2 to 7 is shown. The rocker 6 has a first rocker arm 11, on which the axis of rotation 9 of the circular blade 10 is located, and an opposite rocker arm 12, the width of which is increased relative to the rocker arm 11 and which serves as a counterweight to the circular blade 10. A drive motor not visible in the figures is located in the interior of the machine housing 5 and serves both as a drive for the rocker 6 and for it rotating about its own axis of rotation 9 circular blade 10. The distance 8 corresponds to the radius of an orbit of the center of the circular blade 10th ,

At one in the FIGS. 1 to 5 visible end face of the machine housing 5 is a so-called cutting box 13, in which the rocker 6 and the circular blade 10 are arranged protected in the cutting operation of the machine 1 against external access. The closure of the cutting box 13 is carried out by means of a cutting box door 14, which is mounted on two hinges 15 pivotable about a vertical axis on the machine housing 5 and on the side wall of the cutting box 13.

Within a feed area 2 facing end wall 16 of the machine housing 5 is a passage break 17, which defines a maximum cutting cross-section. A passage break 18 is also located in the cutting box door 14 in order to be able to transfer the slices cut by the cutting device 3 into the removal area 4, which adjoins an outside of the cutting box door 14. The removal area 4 has a removal conveyor belt attached to the knife box door 14, that the cut from the cutting device 3 discs - depending on the choice of removal speed - standing side by side, shingled or lying side by side lying away. Typically, following the machine 1 according to the invention, a fully automatic packaging machine is placed which usually packages a plurality of cut portions into a self-service packaging unit.

Like from the FIGS. 1 to 7 , in particular the scale drawn on a large scale FIGS. 6 and 7 , It can be seen, the breakthrough is 17 from both - viewed in the feed direction - behind the circular blade 10 (ie the removal area 4 facing) cutting frame 20 and from a - viewed in the feed direction - arranged in front of the circular blade 10 cutting frame 21 enclosed on all sides. Both cutting frames 20, 21 each consist of a U-shaped main part 22; 23 and of a rod-shaped connecting leg 24, 25, each of which connects the ends of two U-legs 26, 27 of the main parts 22, 23 on the otherwise open side of the U and thus surrounding the frame circumferentially and thus help him to high stability. The connecting leg 25 of the cutting frame 21 arranged on the side of the advancing region 2 is provided with an arcuate recess 28 which permits a collision-free circulation of the swing arm 12 of the rocker 6. While the rocker 6 is substantially aligned with the cutting frame 21, the circular blade 10, the thickness of which is 6 mm, enters into a gap between the two cutting frames 20, 21, the width of which is only slightly greater than 6 mm, in order to pass smoothly of the circular blade 10 through the gap area. While the cutting frame 21 is a casting, the cutting frame 20 is made of a plastic material to ensure good runflat properties.

While the circular blade 10 in FIG. 1 the better representation of the rocker 6 because of disassembled and therefore not visible, can be determined by the sequence of FIGS. 2 to 5 the course of the circular knife 10, the axis of rotation 9 moves as already stated on a circular path about the axis of rotation 7 of the rocker 6, explained in more detail:

In FIG. 2 is the circular blade 10 in an upward obliquely upward direction upward movement, while the pivot axis 9 facing away from the swing arm 12 moves obliquely down to the left below. In FIG. 3 is shown a position in which the circular blade 10 with its axis of rotation 9, the highest position, ie the swing arm 12 has already passed its lowest position. The circular blade 10 has already penetrated into the cutting cross-section defined by the apertures 17, 18 within the cutting frame 20, 21, starting from the upper left corner, wherein the direction of movement is obliquely downward to the right. The direction of rotation 30 of the rocker 6 and the direction of rotation 31 of the circular blade 10 coincide (see arrows in FIG FIG. 3 ), in order to sufficiently press the material to be cut during the cutting process against the counter-cutting edges formed by the cutting frames 20, 21 (for this below) and thus to reliably avoid lifting off.

In the position according to FIG. 4 Again, the circular blade 10 begins to make the opening 17 (starting from the upper right corner) gradually free, after in a position not shown before this area was also passed through by the circular blade 10. In the position according to FIG. 5 has the circular blade 10 due to further rotation of the rocker 6 the breakthrough 17 already completely abandoned.

Out FIG. 1 It can be seen that the axis of rotation 7 of the rocker is approximately at the level of a horizontal center line 32 of the opening 17. This ensures that the circular blade 10 when entering the cutting cross-section (ie, the opening 17) has an obliquely downward direction of movement, which causes a pressing of the food to be cut against the cutting frame 20, 21. In the case of a too deep arrangement of the axis of rotation 7, in particular in areas below a line that marks the lower edge of the opening 17, there would be a risk that the food during the cutting process of the cutting frame 20, 21 is lifted, whereby the cutting quality would be strongly adversely affected ,

Out FIG. 7 In turn, it can be seen that at the cutting frame 20 facing the removal region 4, a counter cutting edge 33 and at the cutting frame 21 facing the advance region 2 a counter cutting edge 34 is formed. Both counter-blades 33, 34 are formed with sharp edges in relation to the gap formed between them, as can be seen inter alia from the sectional view in FIG FIG. 14 which will be discussed in more detail later.

In FIG. 7 Furthermore, it is shown that the cutting frame 20 facing the removal region 4 is fixedly connected to the cutting frame 21 facing the feed region 2 by means of two screws 35. The cutting frame 21 is in turn fixedly connected to the machine housing 5 or not shown stiffeners or struts with a machine frame in the interior of the machine housing 5. Of course, the screws 35 in the horizontal direction so far to the right of the opening 17 removed that the circular blade 10 can circulate without collision in the gap between the cutting frame 20, 21. The circular blade 10 is - viewed in the radial direction from the outside inwards - after an in section wedge-shaped and toothed on the outer circumference area undercut on both sides, ie reduced in thickness to reduce the friction with the food to be cut.

The structure of the feed area 2 can be in particular the FIGS. 8 to 13 remove: A feed element 36 of a feed device 37 is designed as a slide, which can be moved in the feed direction 38. The advancing element 36 is located within an elongate shaft 39 which has a rectangular cross-section. The advancing element 36 is fastened to a coupling arm 40, which is connected outside the shaft 39 to a sleeve 41 which, together with a round rod 42, forms a linear guide for the advancing element 36. On the other hand, the coupling arm 40 by means of a perforated coupling rail 43 with a lower run 44 (s. FIG. 9 ) of a belt drive 45. The belt drive 45, which is driven by means of a servomotor (not shown), permits a precise and highly dynamic displacement of the advancing element 36. The latter is known in the art with a spiked pressure plate 45, which cooperates with a rear side of a food strand (see later) Fig. 14 ) and provided with pivotable gripper hooks 46 which pass through adapted slots in the pressure plate 45 therethrough.

As in particular from the FIGS. 6 to 8 can be seen, the feed element on its cutting device 3 (ie, the knife box 13) facing side has a Kragelement 47, which forms a rear support area for the food strand. On its upper side, the cantilever element 47 is also provided with engagement elements in the form of spikes, in order to achieve a positive connection with the food and in this way to prevent slippage of the food strand.

In particular the FIGS. 8 to 11 can be seen that the shaft 39 of the feed section 2 is provided with a bottom 48 which extends at different levels:

In an end region 49, the bottom 48 extends horizontally and indeed up to an edge 50 which marks a transition to a transition region 51 adjoining the end region 39 in the feed direction 38. In the transition region 51 of the bottom 48 is inclined ramped and falling in the direction of advance 38. At a further edge 52 of the transition region 51 ends and it connects at a lower level than in the end portion 49, a central region 53 at. As can be seen in particular FIG. 9 results, the central region 53 terminates at a further edge 54, where a rising in the direction of the cutting device 3 to the front transition region 55 begins.

In FIG. 11 It is shown that the transition region 55 merges at a line 56 into the cutting frame 21, which is likewise provided with the same inclination as the transition region 55. This circumstance can also be the FIG. 10 remove.

In addition, is off FIG. 11 It can be seen that the feed cross section increasingly narrows in the transition region 55 and the cutting frame 21 in a lower region, which is approximately 20% of the height of the entire aperture 17. This narrowing is achieved with the aid of a wedge-shaped guide element 57, which is intended to effect a particularly good contact of the food strand with a side surface 58 of the transitional region 55 or a vertical surface 59 of the cutting frame 21, in particular for foodstuffs with a concave side surface. Regarding FIG. 15 this circumstance will be further deepened below. The wedge-shaped guide member 57 has a vertical wall 60 and an inclined triangular wall 61.

How is the FIG. 7 can be found, the wedge-shaped guide member 57 also in the removal area 4 facing cutting frame 20 is continued in the form of the local guide member 62 which is integral with the cutting frame 20.

A longitudinal section through the feed region 2, in which a food strand 63 is in the form of a chop strand, is in FIG. 14 shown. In the position just occupied by the advancing element 36 there is a free space F between a lower side 64 of the food strand 63 and the bottom 48 of the shaft 39 both in the front transition region 55 and the central region 53. If the food strand 63 had such a length, that he would also protrude into the rear transition region 51, which does not apply in the illustrated example case, there would also be a free space to the bottom 48 out there. Since the food strand 63 is held only in two places (front and rear end portion) in the vertical direction, namely on the feed frame 2 associated cutting frame 21 and located on the advancing element 36 Kragelement 47, the food strand 63 depends on its weight and its own Material elasticity slightly down through. Therefore, the clearance F in the center of the food strand 63 despite the lowering of the bottom in the central region 53 has a smaller height than at the Kragelement 47. If the food strand 63 a quasi-infinite rigidity, ie he would not bend under its own weight, so would the free space F in the central region 53 everywhere the same height. This height would correspond to the distance between an underside of the cantilever element 47 and an upper side of the bottom 48 in the middle region 53. In the present case, this height difference is 30 mm. Incidentally, the height difference between the upper side of the bottom 48 in the end region 49 and the upper side of the bottom 48 in the central region 53 is also only slightly less. With the advancing element 36 retracted maximally counter to the advancing direction 38, the front edge of the cantilever element 47 closes with the edge 50 the end portion 49 and the transition region 51 from. The underside of the advancing element 36 and the cantilever 47 then come almost in contact with the top of the bottom 48 in the end portion 49th

Due to the deflection of the food strand 43 whose underside is 64 - in the longitudinal direction considered convex, whereas a top 65 of the food strand 63 is correspondingly concave shaped. As a result, a front end face 66 and a rear end face 67 of the food strand 63 are inclined at an acute angle to each other.

With the aid of a laser scanning device 68 arranged in the transition region 55, the current cross section of the food strand 63 can be determined and, in combination with the corresponding feed amount, a target weight of a portion to be cut off can be set. With the aid of a hold-down device 69 arranged behind the laser scanning device 68, which has a profiled hold-down roller 71 arranged on two extendible punches 70, the food strand 63 can already be fixed to the food strand 63 with its front end section before the circular knife 10 enters Press support area S1 1 in the form of the cutting frame 21. The fixing of the rear end portion of the food strand 63 on the rear support region S2 in the form of the cantilever element 47 takes place with the local spines and with the gripper hooks 46.

For a particularly good cutting behavior and in particular a splitter-free severing of the bone contained in the food strand 63, the combination of the 6 mm with respect to the prior art very thin circular blade 10 in cooperation with the formed on the cutting frame 21 counter blade 34 and the cutting frame 20 trained counter-blade 33. Both counter-blades 33, 34 are at the same level, ie have no height difference to each other.

Out FIG. 15 Finally, it is still clear that the guide member 62 on the cutting frame 20 and also formed on the cutting frame 21 guide member 57 are adapted in the longitudinally on a typically concave shaped food strand 63 in the form of a chop strand. A lower "edge" 72 of the food strand 63 may come into abutment in the corner areas formed on the guide elements 62 and 57, which would not be possible without the wedge-shaped guide elements 62 and 57 due to the protruding upper "edge" 73 of the food strand 63. In this way, the food strand 63 is positioned in the region of the cutting frame 20, 21 and before the penetration of the circular blade 10 in cooperation with the hold-down roller 71 so that a shift and resulting inaccuracies in cutting are excluded. Due to the rotation of the rocker 6 completely outside the cutting cross section, the separation of the slices of the food strand takes place solely by means of the very thin circular blade 10, so that in conjunction with the two supporting counter-blades 33, 34 a large wedge effect and thus splintering of the bones very safe can be prevented.
