Displacement element pair

Description

[0001] The invention relates to a device for dividing a sausage strand with a pair of displacement elements according to claim 1.

[0002] US 5 133 685 A already describes a device for dividing a sausage strand with displacement elements, each with two wing sections. In this document, the displacement elements engage with one another in an interlocking manner during dividing. The wing sections run at an angle to one another. This document does not show that, at least in the region of a cutout that widens, in particular in a V-shape, the distance between a plane in which the displacement edge of a first wing section lies and a plane in which the displacement edge of the first wing section of the opposite displacement element lies, and the distance between a plane in which the displacement edge of the second wing section and a plane in which the displacement edge of the second wing section of the opposite displacement element lies, lies in a range >= the dimension of the displacement wing thickness and <= the dimension of the displacement wing thickness + 4 mm.The subsequently published EP 4 088 581 A1 also does not show this feature.

[0003] To produce sausages, a pasty mass is filled into a sausage casing, for example, via a filling tube, creating a filled sausage strand. In order to divide such an "endlessly" filled sausage strand into equal-length portions during filling, the pasty mass in the product strand is displaced at predetermined intervals using so-called opposing displacement elements, in particular to create a necking point. The sausage strand to be filled can be twisted around its longitudinal axis, for example, using a twisting unit, whereby a necking point then springs into place at the necking point, thus dividing the sausage strand. During production with displacement elements, as currently available on the market, folds form between the displacement elements during the necking process. These folds cannot prevent the twisting of the necking point and the necking point from springing into place, but can nevertheless delay it, meaning that the necking point springs into place later.Viewed in the direction of transport, it only enters further back. This means that the creation of the twisting point or splitting point takes longer and the product casing is subjected to greater stress. Delicate sausage casings can be damaged during the displacement process, severely impacting production.

[0004] Figure 6a shows a perspective view of two opposing displacement elements according to the prior art, which are rotated about their respective axes A in opposite directions. The sausage strand moves between the displacement elements. As can be seen from Figure 6a and 6b Each displacement element has at least one vane with an upper vane section and a lower vane section, which, as shown in Figure 6b shown, interlock in a compartment position. As can be seen from the Figure 6b and 6dAs can be seen, the opposite upper wing sections and the opposite lower wing sections each run at an angle of, for example, 2 times 20 ° to each other. This creates, as can be seen from Figure 6c As can be seen, there is an area between the two upper and two lower surfaces of the wing sections in which the sausage strand expands in a fold-like manner, thereby slowing down the twisting of the sausage casing. The corresponding wing sections are therefore angled relative to each other so that the displacement elements can be positioned as close to each other as possible, while the wings can still move past each other without collision.

[0005] Based on this, the present invention is based on the object of providing an improved device for dividing a sausage strand, which enables the dividing point to intervene quickly and gently.

[0006] According to the invention, this object is achieved by the features of claim 1.

[0007] According to the present invention, the device comprises a pair of displacement elements for dividing a sausage strand transported between the displacement elements into individual sausages. Each displacement element has at least one wing, which has a first wing section and a second wing section, between which an outwardly widening, particularly V-shaped, cutout is formed. Both the first, e.g., upper, and the second, e.g., lower, wing sections each have a laterally curved pocket or opening.

[0008] The curved pocket or opening, each located in an area within the outer contour of the respective wing section, allows the displacement elements to move past each other in such a way that the wing sections do not collide with each other during rotation, because, for example, a first wing section can move past the area of ​​the curved pocket of the corresponding wing section of the opposite displacement element, ie can move through the free space created by the pocket or opening.This makes it possible for the first and second wing sections of the respective displacement elements to be arranged substantially parallel with a small distance from one another in a sectioning position in which the sausage strand is maximally constricted and the two widening, in particular V-shaped cutouts maximally overlap, so that the formation of wrinkles between the surfaces of the wing sections is prevented and the twisting point can spring into place more quickly and gently.

[0009] According to a preferred embodiment, the displacement edge, i.e. the outer contour of the first and second wing sections of a respective displacement element, lies at least in the region of the widening cutout either a) in substantially parallel planes or b) in a common plane. If the displacement edges of the first and second wing sections lie in parallel planes, the wings can interlock in order to separate the sausage strand. If the displacement edges of the first and second wing sections lie in a common plane, the separation can be achieved by wings that are parallel to one another. The planes in particular each run accordingly through the center of the wing width in the region of the widening section.

[0010] This arrangement makes it possible to keep the distance between the wings of the opposing displacement elements small in a sectioning position, at least in the area of ​​the outwardly widening, particularly V-shaped, section. The distance can also be essentially constant. The wing sections do not diverge as in the prior art, effectively preventing the formation of wrinkles and allowing the sausage strand to twist in a very short time during the twisting process, and the twisting point to spring into place. The sectioning point is thus created more gently overall.

[0011] Depending on the thickness of the wing elements, the distance between the planes is preferably within the following range: the thickness of the wing sections + 0 mm to 4 mm, in particular the thickness + 0.1 mm to 3 mm, in particular + 0.2 mm to 1 mm. In this range, no jamming occurs, and the turning point snaps into place quickly and completely. Here, the thickness, in particular the maximum thickness (if the thickness is not constant), of the wing sections in the expanding cutout is considered.

[0012] Advantageously, in case a), the curved pocket in the first wing section of a respective displacement element is curved outwardly to a first side, and in the second wing section, the curved pocket is curved to the opposite side. In case b), the curved pockets in the first and second wing sections are curved to the same side. Thus, the wing sections can move past each other without collision.

[0013] According to a preferred embodiment, in a compartmentalized position in which the sausage strand is maximally constricted and the two widening cutouts are maximally superimposed, the wing of the first displacement element and the wing of the second opposite displacement element can interlock or the wings can be arranged substantially parallel to one another.

[0014] According to a preferred embodiment, the vanes can be arranged in a flag-like manner on a mount, via which they can be connected to a rotating mechanism, which in particular comprises a drive shaft, in order to rotate the displacement elements about an axis or to move them in rotation about several axes. This means that the displacement elements are either rotated at a distance from one another about, for example, their central axis, or are each mounted on a transport means, e.g., a chain or conveyor belt, etc., and rotate.

[0015] The displacement elements of the invention, even when rotated or circulated, offer the same advantages as linearly moving displacement elements, whose vanes can be arranged very close to each other in the compartment position. However, according to the invention, the rotational or circulating movement can increase the production speed.

[0016] The device according to the invention comprises a transport device for transporting the filled sausage strand between the opposing displacement elements. Furthermore, the device comprises a rotation mechanism for rotating the displacement elements about a respective rotation axis or for moving them in rotation about multiple rotation axes.

[0017] Although the displacement elements can also displace the pasty mass without a twisting device, a twisting device for rotating the sausage strand around its longitudinal axis L is advantageous so that a twisting point can be created between the individual sausages. For example, in coextruded sausages, where a sausage casing is extruded together with the pasty mass, no twisting device is necessary. Here, too, the present invention is advantageous because a well-formed separation point can be created without oblique squeezing.

[0018] According to a preferred embodiment, the displacement elements are arranged such that, in a compartment position in which the expanding cutouts of the opposing displacement elements overlap to the maximum extent, the respective displacement edges of the first wing section of one displacement element and the second wing section of the opposing displacement element lie essentially in parallel planes, at least in the region of the respective expanding cutout. Essentially parallel means, for example, a maximum deviation of 0 degrees to ±10 degrees, in particular 0° to 5°, even more preferably 0° to 3°.

[0019] The displacement elements can be rotated about their central axis A1 via the rotation mechanism, with the central axis running essentially parallel to the planes E1, E2, in which the displacement edge of the wing sections lies at least in the area of ​​the widening cutout. Preferably, the central axis or rotation axis extends perpendicular to the transport direction T of the sausage strand.

[0020] According to a preferred embodiment, the opposing displacement elements are each arranged on two transport means rotating around multiple axes, in particular a transport chain or a conveyor belt. The axes of rotation are preferably substantially parallel to the planes in which the displacement edges of the first and second wing sections are arranged in the region of the particularly V-shaped cutout. The axes of rotation preferably run perpendicular to the transport direction of the sausage strand.

[0021] According to a further embodiment, a displacement element has several rotating vanes, or several displacement elements, each with a vane, are arranged on the respective rotating transport means. This allows the throughput to be increased.

[0022] Advantageously, the displacement elements are manufactured using 3D printing or injection molding. By moving away from sheet metal production, new shapes and contours are now possible. While plastic displacement elements have also existed in the prior art, their shape mimicked the contours of the sheet metal elements. 3D printing makes it particularly easy to produce a displacement element with the pockets or recesses according to the invention. However, metal displacement elements can also be manufactured using 3D printing.

[0023] The displacer element pair can, for example, be made of a material from the following group: Plastic, metal, especially stainless steel.

[0024] According to the invention, at least in the region of the cutout which widens in particular in a V-shape, the distance between the plane in which the displacer edge of the first wing section lies and the plane in which the outer contour of the first wing section of the opposite displacer element lies and the distance between the plane in which the displacer edge of the second wing section and the plane in which the displacer edge of the second wing section of the opposite displacer element lies >= the thickness of the wing sections, lies in particular in a range: amount of the thickness of the wing sections + 0 mm to 4 mm, in particular amount of the thickness + 0.1 mm to 3 mm, in particular 0.2 mm to 1 mm. Here, the thickness, in particular the maximum thickness of the wing sections in the widening cutout is taken into account. I.e. the distance lies in a range >= the dimension of the displacer wing thickness and <= the dimension of the displacer wing thickness + 4 mm.

[0025] If the distance between the displacement edges can be kept small in the transport direction, the compartment can be inserted very well and no wrinkles occur because the wing sections of the opposing displacement elements lie close together.

[0026] According to a preferred embodiment, the at least one vane does not extend radially from a mount that rotates about an axis. Thus, opposing vanes can easily move past each other.

[0028] Figure 1shows a schematic representation of an example of a filling machine 20 for producing a filled sausage strand, which is divided into individual sausage strand sections of a predetermined length using the device 10 according to the invention. The filling machine 20 has, in a known manner, a filling funnel 21, through which pasty mass, for example sausage meat, is filled and then pushed into a filling tube 22 via a conveyor system (not shown). At the end of the filling tube there is, for example, a casing brake 23. For twisting the filled sausage strand, a twisting device 14, in particular a twisting gear, which is driven by a motor, is optionally provided here. With the twisting device 14, the filling tube 12 can be rotated about the longitudinal axis L together with the casing pulled onto it.

[0029] The pasty mass is ejected through the filling tube 22 into the casing, e.g. the intestine, which is drawn onto the filling tube 22 and held by the casing brake 23, whereby the filled sausage strand is produced in a known manner.

[0030] Directly behind the filling tube 22 is the device 10 for dividing the filled sausage strand. The sausage strand is to be divided into individual portions of a specific length I by the device 10.

[0031] For this purpose, at least one pair of displacement elements 1a, 1b is provided. Figure 1 In the embodiment shown, a transport device 16 is shown only as an example, which has opposite, circulating transport means, e.g. conveyor belts or conveyor chains, etc., between which the filled sausage strand 11 is transported.

[0032] In this embodiment, as explained in more detail below, the displacement elements 1a, 1b are arranged on the circulating transport means, e.g. the circulating conveyor belt, chain, etc., in particular at uniform intervals. This embodiment will be described below with reference to Figure 2a and 2b explained in more detail.

[0033] Figure 3 schematically shows a displacement element according to an embodiment of the invention. The displacement element has at least one wing 2a, with an upper, i.e., first, wing section 3a and a lower, i.e., second, wing section 4a. Between the two wing sections, an outwardly widening, in particular V-shaped, open-edge cutout 12 is provided. The displacement edges 13 are arranged in the region of the V-shaped cutout 12.

[0034] The at least one displacement vane 2a is arranged in a flag-like manner on a support 7, i.e., it protrudes laterally. The respective displacement vane can extend from the support in a direction that does not correspond to the radial direction. This is advantageous so that the displacement vanes can overlap in the center plane.

[0035] The holder 7 can be connected to a rotating mechanism 15, which for example has a drive shaft, in order to rotate the respective displacement element about an axis A1. The height of the displacement element h is, for example, in a range from 20 mm to 80 mm, in particular 30 mm to 50 mm. The dimension a from the upper point O of the recess 12 to the lower point U of the recess 12 is, for example, in a range from 15 mm to 75 mm, in particular between 25 mm and 45 mm. The depth t of the cutout 12 is, for example, in a range from 5 mm to 30 mm, in particular from 7 mm to 25 mm. The outward extension k of the lower and upper wing sections 3a, 4a is, for example, in a range from 30 mm to 80 mm. The thickness of the wings is, for example, in a range from 1 mm to 6 mm, preferably from 1 mm to 3 mm. Corresponding displacement elements are suitable for sausage calibers in a range from 8 mm to 60 mm.The invention also enables the use of the displacement elements in connection with clipping machines in which larger sausage diameters (e.g. up to 60 mm) are processed.

[0036] Both the upper and lower wing sections 3a, 4a have laterally curved pockets 5a, 6a, which allow opposing displacement elements to move past each other without collision, i.e., the outermost points O and U of the outer contour or the displacement edges 13 can move through the free space formed by the pockets.

[0037] Alternatively, instead of the pockets 5a, 5b, 6a, 6b, it is also possible to simply create an opening in the surface of the upper and lower wing sections within the outer contour of the wings. This also allows the wings to move past each other smoothly. However, the solution with the pockets provides improved stability, and the sausage string can be better supported during separation.

[0038] In connection with Figures 4a to 4d A first embodiment of a displacement element will now be explained, in which the wing sections 3a, 4a arranged one above the other (or laterally next to each other) are offset from each other in parallel planes E1, E2. This is particularly evident in the side view in Figure 4cvisible. The displacer edge 13 of the upper wing section 3a lies in a first plane E1 and the displacer edge of the lower wing section 4a lies in a second plane E2 which is parallel to the plane E1, wherein the planes E1 and E2 have a distance s which lies in a range which depends on the displacer wing thickness in the region of the displacer edge in the widening section 12 (if the thickness is not constant, the maximum thickness is considered): distance s = displacer wing thickness + 0 mm to 4 mm, in particular + 0.1 mm to 3 mm, even more preferably + 0.2 to 1 mm. The wing sections 3a, 4a border on one another in a transition region. The planes E1 and E2 are preferably parallel to the axis of rotation, in particular parallel to a plane which is spanned by a vector along the axis of rotation A1 and a vector perpendicular to the axis of rotation A1.

[0039] In this embodiment, in the upper wing section 3a, 3b of a respective displacement element 1a, 1b, the curved pocket 5a, 5b is formed to a first side, in Figure 4c to the left, curved outward. In the lower wing section 4a, 4b, the pocket 6a, 6b curves toward the opposite side. Figure 4d shows a cross-section through the pockets 5a. The curvature creates a free space such that the wings can move past each other without collision. Figure 4In the embodiment shown, the upper (first) and lower (second) wing sections 3a, 3b, 4a, 4b of the opposing displacement elements 1a, 1b engage with each other in an interlocking manner. This means that in a compartmentalized position in which the sausage strand 11 is maximally constricted and the two V-shaped widening sections 12 overlap maximally, the upper wing section 3a of the first displacement element and the lower wing section 4b of the second displacement element lie in a plane E1, and the upper wing section 3b of the second displacement element and the lower wing section 4a of the second displacement element lie in a plane E2. Such a compartmentalized position is shown in the bottom illustration in Figure 4a shown.

[0040] The topmost representation in Figure 4ashows how the displacement elements rotate in the direction of the arrow around the respective axes A1 and begin to divide the incoming sausage strand 11 and displace the pasty mass. The pockets allow the wings to move past each other without blocking, and a distance between the two rotation axes of, for example, 50 mm to 150 mm can be achieved. The wings 2a, 2b move towards each other until they are in the dividing position, as shown in the bottom illustration in Figure 4acan be seen. If the sausage strand 11 to be filled is twisted via the twisting device, the twisting point 30 can now engage and the sausages are divided. The wings 2a, 2b then move apart again in the direction of the arrow. The pockets 5a, 5b, 6a, 6b allow the wings 2a, 2b to move apart again without collision. The drive is via a rotating mechanism 15 which can be connected to the holder 7, here via the driven shaft 16. The depth of the pocket p results from the center distance of the drive axles and the design of the displacement elements. The pockets bulge outwards at the sides and can, for example, be essentially oval.

[0041] An opening not shown is also designed in such a way that the displacement elements can move past each other accordingly.

[0042] Figure 5c shows a further embodiment which is essentially the same as in connection with Figure 4shown embodiment, with the exception that the displacement edges 13 of the upper and lower wing sections, 3a, 3b, 4a, 4b of a respective displacement element lie in a common plane E1 at least in the region of the widening section 12, ie they are not offset from one another. Otherwise, this embodiment corresponds to the one described in connection with Figure 4a In a compartmentalized position in which the sausage strand 11 is maximally constricted and the two widening cutouts 12 are maximally superimposed, the wings 2a, 2b are arranged essentially parallel to one another, as can be seen from the bottom illustration in Figure 5aHere, too, the recesses or pockets 5a, 5b, 6a, 6b allow the wings to move past one another without collision. In the compartment position, for example, the upper and lower wing sections 3a, 4a of the first displacement element lie in a plane Ea, and the upper wing section 4a and lower wing section 4b of the second displacement element 2b lie in a plane Eb parallel to plane Ea, which, as previously described, are parallel to a plane spanned by a vector along the axis of rotation A1 and a vector perpendicular to the axis of rotation A1.

[0043] The distance between the planes is also in this case, for example, in a range of the dimension of the displacement vane thickness in the region of the displacement edges in the widening region 12 plus +0 mm to 4 mm, in particular 0.1 to 3 mm, preferably 0.2 to 1 mm, at least in the region of the widening recess 12.

[0044] Figure 5bshows in detail how the wings 2a, 2b can move towards each other.

[0045] In the Figure 4a and 5a In the devices shown for dividing a sausage strand, the sausage strand is conveyed in the transport direction T via a transport device not shown, e.g. by two opposing conveyor belts.

[0046] In the Figure 4 and 5 In the embodiment shown, the displacement elements each rotate around an axis A1, in particular the central axis - i.e., they rotate. However, it is also possible for the displacement elements to rotate around several axes of rotation A1, A2, as can be seen in particular from Figure 2a and 2b The displacement belts can be used as in Figure 2aarranged one above the other. However, the axes can also be vertical, so that the two displacement belts are arranged next to each other. In this case, the first and second wing sections are not arranged one above the other, but next to each other. Otherwise, the design of the displacement elements is exactly the same as in the previous embodiments.

[0047] As from Figure 2b As can be seen, a displacement element, which here has a wing 2a, is fastened to a transport means 8 via the holder 7. Here, too, the wing 2a has a first and second wing section 3a, 3b, which here, for example, as in connection with the Figure 4 shown embodiment, ie are arranged offset from each other. Even if not shown, the first and second wing sections 3a, 3b and 4a, 4b can be arranged as in connection with the Figure 5 shown embodiment be arranged in one plane.

[0048] As from Figure 2a As can be seen, the displacement elements are arranged at predetermined intervals on a transport means, here on a conveyor belt 8, which rotates around two axes A1, A2 and which simultaneously serves as a transport device in the transport direction T. However, the belt can also rotate around several axes of rotation.

[0049] As is particularly evident from Figure 2a As can be seen, the wings 2a, 2b move towards each other, whereby the sausage strand is conveyed between the displacement elements in the transport direction T.

[0050] The wings 2a, 2b engage, as in connection with the Figure 4 and 5 shown, either crosswise into each other or lie parallel to each other. Figure 2aIn the embodiment shown, the first and second displacement elements 1a, 1b engage with one another in an interlocking manner. At the point marked AT, the two wings 2a, 2b are engaged, i.e. in the sectioning position. This is where the twisting point can step in. The displacement element pairs moved by the belts 8a, 8b carry the divided sausage strand in the transport direction T. The circulating transport means 8a, 8b thus also serve as a transport device. Guide elements can be arranged on the transport means between the displacement element pairs, which ensure that the sausage strand does not deviate sideways, particularly in the case of longer sausages, but is conveyed along its longitudinal axis in the transport direction T.

[0051] Figure 7shows that the parallel alignment of the displacement edges of the wings 2a, 2b and the small distance between the wings, at least in the area between the outer points O and U, which is preferably constant, can prevent a corresponding fold from forming between the wings of the displacement elements, as in Figure 6c has been shown. In Figure 7 one can clearly see that the wings 2a, 2b are arranged in two spaced parallel planes Ea, Eb.

[0052] In the previously shown embodiments, the displacement elements are designed such that the cutouts 12 overlap, particularly in a diamond shape, leaving a small opening so that the sausage strand is not sheared off. However, it is also possible to design the pair of displacement elements or space them apart from each other such that the cutouts completely overlap and the sausage strand is severed to produce individual sausages. For this purpose, the displacement edge of at least one displacement element can be at least partially designed as a blade or have a blade.

[0053] Several wings can be arranged around the circumference of a holder 7 of a displacement element and several displacement elements on the circulating transport means 8. Thus, the production speed can be increased.

[0054] According to a preferred embodiment, the device further comprises a twisting device 14 for rotating the sausage strand 11 to be filled about its longitudinal axis L and / or, for example, in the transport direction after the displacement elements 1a, 1b, a device for clipping or a device for tying or gluing or welding the sausage strand after displacement.

[0055] Figure 8 shows another possible embodiment of a wing that also has a V-shaped cutout 12 and is particularly suitable for larger calibers up to 60 mm. Here, the wing sections are designed such that they have the largest dimension t at the top and bottom, i.e., points O and U are located at the top and bottom edges.
