Description

Technical Field

[0001] The present invention relates to an assembly comprising a slider and a track according to the preamble of claim 1, and also to the application of the assembly in the manufacture of food. Background Technology

[0002] Such assemblies, comprising sliders and tracks, are also commonly referred to as sliding bearing assemblies. The slider and track are correspondingly configured elements of a sliding bearing assembly. With the track typically fixed in a stationary position to a structural element (e.g., a wall or floor of a room), the slider can be guided to move along the track. The track typically extends longitudinally, and the slider can move longitudinally relative to the track while being guided on the track such that its position relative to the track is fixed perpendicular to the longitudinal direction. The track typically has a longitudinal extension length that is at least 4 times, particularly at least 5 times, and particularly at least 10 times, the longitudinal extension length of the slider. As the slider moves along the track, it slides along the track. To ensure this function, the track typically has a guide section, and the slider has a guide receiving portion configured as a through-hole. This through-hole is a through-hole extending longitudinally, i.e., having a continuous net cross-section over its entire longitudinal extension, so that the guide section of the track can be introduced into the guide receiving portion (i.e., the through-hole). Accordingly, the guide receiving section (or guide section) has a boundary wall that defines the net cross-section of the guide receiving section. Here, the term "cross-section" currently refers to a cross-section perpendicular to the longitudinal direction. Accordingly, the boundary wall defines the net cross-section by surrounding an axis extending parallel to the longitudinal direction of the guide receiving section. In any case, the boundary wall surrounds the mentioned axis of the guide receiving section to such an extent that when the guide section of the track is arranged in the guide receiving section, the boundary wall can fix the position of the guide section relative to the slider in all directions perpendicular to the longitudinal direction. Thus, by arranging the guide section in the guide receiving section, it is ensured that the slider is guided relative to the track perpendicular to the longitudinal direction, while the slider can move relative to the track in the longitudinal direction. Accordingly, in the given operating state of the assembly, the slider is supported on the track in a way that allows it to move relative to the track in the longitudinal direction. In operation, the guide section of the track is received in the guide receiving part of the slider. In operation, the boundary wall constitutes a stop for the movement of the guide section relative to the guide receiving part in each direction perpendicular to the longitudinal direction. This is for each possible rotational position of the guide section relative to the guide receiving part (which is feasible in operation), wherein the rotational position involves rotation about the axis of the guide receiving part, which extends parallel to the longitudinal direction. Therefore, in operation, the guide section can only move to and abut against the stop constructed by the boundary wall of the guide receiving part in each direction perpendicular to the longitudinal direction.

[0003] Such sliding bearing assemblies have proven particularly advantageous in industrial production processes because they allow mechanical components, secured to a slider, to move very easily and purposefully along a track. Typically, to reduce friction between the track and the slider, these sliding bearing assemblies have a sliding element fixed to the slider and forming the inner wall of the guide receiving portion; additionally or alternatively, a sliding lubricant may be provided between the track and the slider to minimize friction. However, such sliding bearing assemblies are less suitable for applications in food production processes, where it is essential to prevent undesirable food contamination. For example, lubricants placed between the track and the slider can cause such undesirable contamination. Even when using sliding elements, for example, made of a sliding material (thus avoiding the need for lubricants), the risk of contamination remains. This is because such sliding elements are typically mounted in the slider with the tightest possible fit and against the track with the tightest possible fit, where, although clearance should be reduced to a minimum, it cannot be completely avoided. Such gaps between the sliding element and the track, or possible gaps between the sliding element and the slider, can act as accumulation sites for contaminants, which are difficult to clean and may contaminate food during the production process. Therefore, such sliding bearing assemblies can, when necessary, meet the high hygiene requirements of food production processes with extremely high and costly cleaning efforts. Summary of the Invention

[0004] The present invention is based on the following objective: to provide a component having a slider and a track and / or an application of such a component, which is able to at least partially solve at least one disadvantage of conventional components or their applications.

[0005] To address the objective of this invention, a component having the features of claim 1 is proposed. The component according to the invention comprises a slider and a track extending longitudinally in the longitudinal direction. The invention is particularly preferably applicable to a component in which a load of at least 1000 N, especially at least 1500 N, especially at least 2000 N, can be applied to the slider in a load direction perpendicular to the longitudinal direction, and during the application of the load, the slider can slide relative to the track in the longitudinal direction. The track has a guide section, and the slider has a guide receiving portion corresponding to the guide section, configured as a guide portion. The guide receiving portion has a net cross-section defined by a boundary wall surrounding the guide receiving portion along an axis extending parallel to the longitudinal direction. In one embodiment, the boundary wall defines the net cross-section uninterruptedly; in another embodiment, the boundary wall defines the net cross-section only in sections. In any case, the preferred configuration of the boundary wall defining the net cross-section is such that, when the guide section is arranged in the guide receiving portion, the position of the guide section relative to the guide receiving portion can be fixed by the boundary wall in all directions perpendicular to the longitudinal direction. The guide section and the guide receiving section are configured to match each other such that the guide section can be arranged in the guide receiving section (i.e., the net cross-section of the guide receiving section), and its position relative to the guide receiving section (i.e., relative to the slider) in the vertical direction is fixed, while the slider can move along the track (i.e., along the guide section) in the vertical direction. In the operating state of the assembly, the slider is supported on the track, movable relative to the track in the vertical direction. Furthermore, in the operating state, the guide section of the track is received in the guide receiving section of the slider, wherein the boundary wall is constructed with stops for the movement of the guide section relative to the guide receiving section in each direction extending perpendicular to the vertical direction. Here, the stops ensure that this movement restriction exists for each possible rotational position of the guide section relative to the guide receiving section in the operating state (involving rotation about the axis of the guide receiving section). The assembly according to the invention may have the features described above relating to such assemblies in various embodiments.

[0006] According to the invention, the boundary wall has a plurality of stop sections distributed and configured to provide stops around the axis of the guide receiver. A flushing clearance is provided between each pair of adjacent stop sections in the boundary wall. The stop sections are distributed around the axis of the guide receiver, i.e., they are arranged side-by-side in a specific rotational direction about the axis. However, there are always two adjacent stop sections in the rotational direction separated from each other by the flushing clearance. The stop sections collectively constitute the stop. Therefore, when the guide section moves relative to the slider in any direction perpendicular to the longitudinal direction from the operating state, the guide section only moves in that direction as far as it abuts against one of the stop sections, and this applies to every possible rotational position of the guide section relative to the guide receiver in the operating state. Thus, the stop sections collectively constitute the stop, which forms the boundary wall, and by means of this stop, the relative position of the guide section relative to the guide receiver (and thus relative to the slider) can be fixed in any direction relative to the longitudinal direction. Since the two stop sections are spaced apart from each other by the flushing voids in the direction of rotation, component cleaning between the stop sections within the flushing voids is possible during operation. Particularly preferably, the flushing voids extend over the entire longitudinal length of the guide receiver. Generally preferably, the flushing voids are configured such that, during operation, they can be cleaned with a cleaning fluid that flows longitudinally through the flushing voids over the entire length of the guide receiver. Therefore, the flushing voids have sufficient cross-section to ensure that, in the component operating state (i.e., when the guide sections are located in the guide receiver), the cleaning fluid (e.g., water or a water-based cleaning fluid comprising water and chemicals dissolved in water) can be carried into the flushing voids, allowing them to be flushed over their entire length (which has said entire length in the longitudinal direction). Therefore, it is preferable to spray cleaning fluid onto the component with a cleaning jet while the component is in operation, to rinse it along the entire length of the rinsing void, wherein, for example, the cleaning jet used to rinse the rinsing void along its entire length may have a pressure of 20 to 120 bar (e.g., 25 bar). Additionally or alternatively, according to the invention, the guide section has an outer side configured to correspond to a stop constructed by the boundary wall of the guide receiver, wherein the outer side has stop regions distributed around the axis of the guide receiver, and by the abutment of the stop regions on the stop, the movement of the guide section relative to the guide receiver is restricted for each rotational position of the guide section about the axis of the guide receiver, wherein rinsing slots that can be rinsed in operation are provided between corresponding two adjacent stop regions. The rinsing slots and stop regions of the guide section may generally have features and functions similar to those of the rinsing void and stop sections of the guide receiver.For example, the flushing inlet can be arranged in a corresponding manner relative to the stop area, and can be flushed with cleaning fluid along its entire length (i.e., longitudinal extension). The combined effect of the flushing inlet and the stop area here achieves the same purpose, as described in its description of the flushing void and the stop section: the movement of the guide section relative to the guide receiving part in any direction perpendicular to the longitudinal direction is restricted only when the stop area abuts against the stop constructed by the boundary wall; while the flushing inlet is always spaced from the boundary wall perpendicular to the longitudinal direction, thereby easily achieving sufficient cleaning of the component in the operating state. Therefore, the object of the invention can be achieved on the one hand by providing a flushing void and a stop section in the guide receiving part, and on the other hand by providing a flushing inlet and a stop area in the guide section. To avoid repetition, the invention will be described below mainly in conjunction with the arrangement of the flushing void and the stop section, but these descriptions can also be applied accordingly to the arrangement of the flushing inlet and the stop area.

[0007] Therefore, the present invention is based on the following particular understanding: a sliding bearing assembly comprising a track and a slider can be realized, in which the slider can be adequately guided relative to the track, while still ensuring the simplicity and clarity of the assembly, by configuring the boundary wall of the guide receiving portion of the slider such that: on one side, the boundary wall has a stop section that fixes the position of the guide section of the track relative to the slider; and on the other side, a flushing void is provided next to the stop section, by means of which the assembly can be thoroughly and easily cleaned. In terms of the direction of rotation, the lateral boundary of the flushing void is provided by the boundary wall itself, which has a flushing void on one side and a stop section on the other. Therefore, the inventors recognize that the guide receiving portion is preferably constructed with such a boundary wall, enabling guidance and easy cleaning of the assembly in the area between the guide section and the slider.

[0008] In one embodiment, the guide receiver is constructed from a slider portion of a slider, which is made of a sliding material, particularly a friction polymer. Generally, the sliding material is preferably a sliding plastic. Here, it is currently understood as a polymer material having a low coefficient of friction relative to stainless steel (as the sliding mating part). Preferably, the sliding plastic has a coefficient of friction of <0.3, particularly <0.25, particularly <0.2, relative to stainless steel (without lubrication). The sliding plastic can be a thermoplastic polymer, such as polyethylene, polypropylene, polyacetal, polycarbonate, polyamide, polyvinyl chloride, polytetrafluoroethylene, and thermosetting phenolic resins. To further reduce friction, these plastics can be filled with a lubricant, particularly a solid lubricant containing fine particles, such as molybdenum disulfide or graphite. Such lubricant-containing polymers are also called friction polymers. Because the slider portion of the guide receiver slider (which is made of a sliding material) is constructed from this material, sufficiently low friction between the track and the slider can be ensured when the slider moves relative to the track in the longitudinal direction without the need for lubricant. This is particularly advantageous for using components according to the invention in food production processes to avoid food contamination. Particularly preferred is that the slider portion is constructed as a rigid body section of the slider, which, due to its stiffness, determines the slider's position relative to the track during operation. The inventors recognized that this allows the entire slider portion (i.e., the entire body section) to be made of a sliding material with such stiffness, eliminating the need to combine conventionally used die-cast sliders with sliding elements made of the sliding material (as previously mentioned, this introduces a potential risk of contamination), thus achieving a fixed position of the slider relative to the track in all directions perpendicular to the longitudinal direction. In a particularly preferred embodiment, the entire slider is made of the sliding material. In one embodiment, the slider portion is constructed as a guide unit, which will be described in detail below, fastened to the slider body and specifically designed for guiding the slider relative to the track. Generally, it is preferred that such a slider portion or slider made of the sliding material be manufactured by injection molding or by machining (especially milling) a semi-finished product previously extruded from the sliding material.

[0009] In one embodiment, corresponding two adjacent flushing openings or flushing slots are spaced apart by stop sections or stop areas arranged between them in the rotational direction about the axis of the guide receiver. Accordingly, the flushing openings or flushing slots are arranged adjacent to each other in the rotational direction. Preferably, the two adjacent flushing openings or flushing slots, and the stop sections or stop areas arranged between them, extend parallel to each other and parallel to the longitudinal direction. Particularly preferred is that the flushing openings or flushing slots extend in the rotational direction at an angle range that is at least 0.7 times, especially at least 0.9 times, especially at least 1.0 times, especially at least 1.2 times, especially at least 1.5 times, especially at least 2.0 times, the angle range of the stop sections arranged between them extending in the rotational direction. It should be considered that the extension of the stop section in the rotational direction (i.e., its angular range) is defined such that the stop section can provide a stop for the guide section within this angular range when the guide section moves away from the axis of the guide receiver in the operating state. Accordingly, the extension of the stop area along the rotation direction (i.e., the angular range of its extension) is defined such that, within this angular range, the stop area can abut against the stop provided by the boundary wall when the guide section moves away from the axis of the guide receiving unit in the operating state. Because the flushing void or flushing slot has sufficient width with respect to the rotation direction, it provides the feasibility of fully flushing or cleaning the component in the operating state. Therefore, the boundary wall has, on the one hand, a stop section that abuts against when the guide section attempts to move relative to the slider in a specific direction perpendicular to the longitudinal direction; and on the other hand, a flushing void constructed by the boundary wall of a region that the guide section cannot reach from the operating state because it first abuts against the stop section. Therefore, the sufficient width of the flushing void ensures that, in any possible position of the guide section in the guide receiving unit, there is always sufficient intermediate space between the boundary wall and the guide section, ensuring cleaning feasibility.

[0010] In one embodiment, the flushing openings are each constructed as flushing channels with a bottom formed by a boundary wall, and the bottom of the channel connects to the stop sections adjacent to the respective flushing openings. Therefore, the flushing openings are not constructed as openings in the boundary wall, but rather as flushing channels provided within the boundary wall. It should be considered that, relative to the aforementioned direction of rotation, each flushing channel is adjacent to a stop section constructed by the boundary wall on each of its two sides. Particularly preferred is that, in a direction perpendicular to the axis of the guide receiving portion and extending through the bottom of the channel, the distance between the bottom of the channel at its furthest point from the axis of the guide receiving portion and the position where the flushing channel is adjacent to the adjacent stop section is at least 2 mm, and particularly at least 3 mm. Here, as mentioned earlier, the transition between the flushing trough and the stop section (i.e., the position where the flushing trough abuts the stop section) is determined in such a way that, when the guide section moves relative to the slider in a specific direction perpendicular to the longitudinal direction, from the operating state, the guide section can just abut at this transition point (i.e., at this exact position); while the flushing trough is characterized by the guide section not being able to abut it. Therefore, the aforementioned distance represents the depth of the flushing trough in the direction extending perpendicular to the axis of the guide receiving portion. Thus, the flushing trough has a depth of at least 2 mm, and particularly 3 mm, in this direction. The inventors recognize that such a depth is particularly advantageous for ensuring particularly easy flushability. Accordingly, the flushing trough openings can be configured as flushing troughs with a trough bottom formed from the outside and interconnected with the stop area adjacent to the corresponding flushing trough opening. Preferably, in a direction perpendicular to the axis of the guide section (which, in operation, preferably coincides with the axis of the guide receiving section) and extending through the bottom of the tank, the bottom of the tank, at its position closest to the axis of the guide receiving section, is spaced at least 2 mm, and particularly at least 3 mm, from the position of the flushing tank adjacent to the stop area thereon. This distance correspondingly represents the depth of the flushing tank.

[0011] In one embodiment, the rinsing clearance or rinsing groove has a length of at least 2 mm along the longitudinal extension of the guide receiving portion. 2 Especially at least 3mm 2 Especially at least 5mm 2The flushing void has a cross-section. This allows for the flow of cleaning fluid through the flushing void, or the flushing void to be flushed by the cleaning fluid. In one embodiment, the flushing void forms a common flushing cross-section along the longitudinal extension of the guide receiving portion, which is at least 10%, particularly at least 20%, particularly at least 30%, of the cross-section enclosed between the stop sections. Thus, the common flushing cross-section of the flushing void accounts for a considerable share of the entire net cross-section of the guide receiving portion, in which the guide sections are received during operation. According to the current definition, the cross-section enclosed between the stop sections is defined by an imaginary line surrounding the axis of the guide receiving portion, which is formed by the side of the stop section facing the axis (i.e., passing through the stop section itself on its extension) and by connecting lines between the stop sections that connect adjacent stop sections by straight lines. This surrounding line extends in a plane perpendicular to the longitudinal direction. The connecting lines extend to the nearest end of the adjacent stop section facing the axis of the guide receiving portion. Accordingly, it can be configured such that, along the longitudinal extension length of the guide section, each flushing slot has a minimum length of 2mm. 2 Especially at least 3mm 2 Especially at least 5mm 2 The flushing slot cross section; and / or, along the longitudinal extension of the guide section, the flushing slots collectively form a common flushing cross section, which is at least 10%, especially at least 20%, especially at least 30% of the cross section of the guide section.

[0012] In one embodiment, the rinse void has a width that increases along an extension direction perpendicular to and away from the axis of the guide receiver. The width of the rinse void refers to its extension in the aforementioned rotational direction, i.e., its extension perpendicular to both the longitudinal direction and the aforementioned extension direction. Because the width of the rinse void increases along the explained extension direction away from the axis, good guidance of the guide section in the guide receiver (because the stop section has sufficient width) and good rinseability are both ensured (because the rinse void has sufficient cross-section). Preferably, the rinse void has a width in the aforementioned extension direction (which is perpendicular to the longitudinal direction and especially perpendicular to the aforementioned rotational direction), the width of which, originating from its end in that extension direction toward the axis, increases continuously at least initially with increasing distance from the axis, and then decreases particularly thereafter. Particularly preferred is that the width of each rinsing opening is determined by sidewalls constructed of boundary walls, which are opposite each other in the rotational direction. These sidewalls are configured without sharp angles, and particularly along their entire extension, they have a bending radius of at least 3 mm relative to a bending section extending parallel to the longitudinal direction, wherein the sidewalls extend parallel to the longitudinal direction. Correspondingly, the rinsing slot can be configured to have an increasing width along its extension direction perpendicular to and toward the axis of the guide receiving portion.

[0013] Generally, the rinsing cavities or rinsing slots are preferably evenly distributed around the axis of the guide receiving portion. Generally, at least three, especially at least four, and particularly exactly four rinsing cavities or rinsing slots are preferably provided. Generally, the rinsing cavities are preferably arranged in a trilobal pattern around the axis of the guide receiving portion. Generally, the boundary wall preferably has a curvature relative to at least one curvature axis parallel to the axis of the guide receiving portion, wherein the boundary wall has a curvature radius of at least 3 mm at any location. The boundary wall preferably has a curvature around the axis of the guide receiving portion, such that it has bends in different sections around correspondingly different curvature axes (which are parallel to the axis of the guide receiving portion and thus extend parallel to the longitudinal direction), wherein it is ensured that it does not have bends with a curvature radius less than 3 mm. By avoiding small curvature radii in the bends of the boundary wall, particularly good cleaning feasibility of the boundary wall is ensured. Generally, the boundary wall preferably extends parallel to the longitudinal direction for at least 80% (especially at least 90%) of its entire extension, especially extending parallel to the longitudinal direction throughout its entire planar extension. Accordingly, it is preferably configured that the outer side of the guide section has a curvature relative to at least one bending axis (which extends parallel to the axis of the guide receiving portion), wherein the outer side has a bending radius of at least 3 mm at any position. The outer side preferably has this curvature around the axis of the guide receiving portion, such that it has bends in different sections around correspondingly different bending axes (the bending step line extends parallel to the axis of the guide section, about which the guide section can rotate, and thus extends parallel to the longitudinal direction), wherein it is ensured that the outer side does not have a bend with a bending radius less than 3 mm. Generally, it is preferred that the outer side extends parallel to the longitudinal direction for at least 80% (especially at least 90%) of its entire extension, particularly extending parallel to the longitudinal direction over its entire planar extension.

[0014] In one embodiment, the track has at least one additional guide section, and the slider has at least one additional guide receiving portion configured as an additional through-hole. In an advantageous embodiment, the additional guide section and the additional guide receiving portion may have the features described above for the guide section or guide receiving portion or their combined action. For example, the additional guide receiving portion may have a net cross-section defined by a boundary wall (which thus belongs to the additional guide receiving portion) surrounding an axis parallel to the longitudinal direction of the additional guide receiving portion, wherein, in the operating state of the assembly, the additional guide section of the track is received in the additional guide receiving portion of the slider, and the boundary wall of the additional guide receiving portion constitutes a stop for the movement of the guide section relative to the additional guide receiving portion in each direction perpendicular to the longitudinal direction. Preferably, the boundary wall of the additional guide receiving part has multiple stop sections, which are distributed around the axis of the guide receiving part and form the stops of the additional guide receiving part. A rinsing clearance is provided between each pair of adjacent stop sections in the boundary wall of the additional guide receiving part. And / or, the additional guide section has an outer side configured to correspond to the stops constructed by the boundary wall of the additional guide receiving part. This outer side has stop areas distributed around the axis of the additional guide receiving part. By abutting against the stops through these stop areas, the movement of the additional guide section relative to the additional guide receiving part is limited for each rotational position of the additional guide section around the axis of the additional guide receiving part. A rinsing slot is provided between each pair of adjacent stop areas. Providing two guide sections and two guide receiving parts (where each guide section corresponds to exactly one guide receiving part, and in operation, each guide section is arranged in its corresponding guide receiving part) ensures particularly reliable guidance of the slider on the track. Furthermore, different guide sections or guide receivers can each perform different functions. For example, the pairing of one guide section and guide receiver can ensure only particularly rigid guidance of the slider relative to the track, while the combined action of another guide receiver and another guide section enables the slider to be driven relative to the track for longitudinal movement along the track. In other particularly advantageous embodiments, the track has at least two additional guide sections, and the slider has at least two additional guide receivers, wherein these two additional guide sections and two additional guide receivers can be advantageously constructed as described for the guide sections, or for the guide receivers, or for their combined action. By providing multiple such additional guide sections or guide receivers (as previously described, which can be configured to match each other and can act simultaneously in operation as explained), improved guidance of the slider on the track and improved operability can be achieved.

[0015] In one embodiment, the guide receiver and other guide receivers are constructed from a one-piece slider body, or from a one-piece guide member fastened to the slider body. The guide member can be, for example, a guide unit as described in detail below, or a slider portion as described above. Correspondingly, in the case of multiple additional guide receivers, the multiple additional guide receivers and the guide receivers can be constructed from a one-piece slider body, or from an integral guide member fastened to the slider body. Since the guide receivers are constructed entirely from a single component, particularly simple manufacturing of the assembly is ensured, and particularly advantageous guidance of the slider relative to the track is also ensured.

[0016] In one embodiment, the guide section and other guide sections are constructed from corresponding additional, independently manufactured components of the assembly. Particularly preferred is that the two components constructing a corresponding guide section are interconnected (especially rigidly interconnected) by a connecting member. Particularly preferred is that the guide section (especially the entire track) is made of stainless steel. Because the guide sections are manufactured as corresponding independent components, the track can be manufactured particularly cost-effectively, simply, and easily cleaned. Particularly preferred is that the connecting member has a bottom side by which the track can be pre-secured to a component, wherein all exterior surfaces of the connecting member other than the bottom side have only this surface inclined towards a predetermined plane. This inclined configuration makes the assembly particularly clear. Particularly preferred is that all surfaces of the guide section and / or all surfaces of the slider also inclined towards this predetermined plane. Generally, it is preferred that the entire assembly is constructed without sharp edges on its entire exterior. Particularly preferred is that the bottom side is constructed to be mounted on the surface of the structural element by means of its bottom side, which lies within the predetermined plane. In the intended use of the component, the track can therefore be secured to one side of the structural element via the bottom side of the connecting member, the surface of which extends in a predetermined plane, wherein, preferably, this plane extends at least by a component (especially completely) perpendicular to the force of gravity acting on Earth. Particularly good cleaning of the component can be achieved by providing surfaces inclined toward the predetermined plane on all sides of the connecting member other than the bottom side (i.e., all sides other than the bottom side), because cleaning fluid can flow particularly well from the respective sides or the outside.

[0017] In one embodiment, the stop section constructed by the boundary wall of the guide receiving portion together forms an internal thread, wherein the guide section is constructed as a screw with an external thread corresponding to the internal thread. Correspondingly, the stop can be configured to have an internal thread, while the guide section is constructed as a screw with an external thread matching the internal thread, the external thread being formed by the stop region. Therefore, it is particularly advantageous to configure the slider to move relative to the track (or screw) by rotating the guide section, constructed as a screw, relative to the slider in the longitudinal direction. The inventors have found that with this configuration, the guide receiving portion can be constructed as a washable nut type, which, on the one hand, constructs the internal thread of the screw through its stop section, and on the other hand, facilitates easy cleaning of the assembly through its flushing groove; in this assembly, rotation of the screw in the longitudinal direction generates longitudinal movement of the slider relative to the track. Therefore, the above embodiment is particularly advantageous for implementing a sliding bearing assembly in which the slider should be easily moved relative to the track by a drive mechanism. Naturally, the external thread has a thread diameter formed by the outer side of the thread. Preferably, the thread diameter has a value between 10 mm and 30 mm, particularly between 10 mm and 20 mm. It has been particularly advantageous to design the guide section and the guide receiving portion in a corresponding configuration, i.e., by providing the aforementioned flushing recess or flushing slot, such that in operation, a net cross-section is formed between the guide section and the guide receiving portion in any possible rotational position of the guide section relative to the guide receiving portion. This net cross-section has a circular area whose diameter is equivalent to the thread diameter of at least 20%, particularly at least 30%, particularly at least 50%, particularly at least 70%, particularly at least 100%, particularly at least 120%, particularly at least 150%. Generally, it is preferred that the flushing recess or flushing slot has a maximum width perpendicular to the longitudinal direction, said maximum width being at least 0.3 times, particularly at least 0.5 times, particularly at least 0.7 times the thread diameter.

[0018] In one embodiment, the additional guide section is constructed as a smooth shaft. Currently, the term "smooth shaft" refers to a shaft whose outer side does not have steps that would hinder the sliding of a body that slides longitudinally against it. Particularly preferably, in one embodiment, the smooth shaft is defined as having a constant cross-section perpendicular to the longitudinal direction over its entire longitudinal extension. Because the additional guide section is constructed as a smooth shaft, it facilitates reliable guidance of the slider on the track without impeding relative movement of the slider relative to the track in the longitudinal direction. With both the guide section and the additional guide section (constructed as a smooth shaft), the slider can be guided particularly reliably on the track and can move particularly easily relative to the track in the longitudinal direction. In one embodiment, where the guide section (as described above) is constructed as a screw, the guide receiving portion is constructed with an internal thread, and the other guide section is constructed as a smooth shaft, the slider can be driven particularly easily to produce movement of the slider relative to the track in the longitudinal direction; simultaneously, the other guide sections ensure that the slider rotation is reliably prevented when the screw rotates about an axis extending parallel to the longitudinal direction. In a particularly advantageous embodiment, the guide section (as described above) is constructed as a screw, and the track has first and second additional guide sections, each constructed as a smooth shaft, wherein preferably the two additional guide sections are spaced less than 50 cm apart, particularly less than 30 cm, and especially less than 20 cm. Particularly preferably, the guide section constructed as a screw is arranged between the first and second additional guide sections. Correspondingly, particularly preferably, the guide receiving portion is arranged between the first and second additional guide receiving portions. Generally, preferably, the corresponding guide receiving portion corresponding to the guide segment constructed as a smooth axis is also constructed as a smooth guide receiving portion. This allows the guide receiving portion to correspond to the guide segment constructed as a smooth axis, thereby ensuring that the corresponding guide receiving portion moves in the longitudinal direction with minimal friction and pure translation relative to the corresponding guide segment. Preferably, the smooth guide receiving portion has a constant cross-section perpendicular to the longitudinal direction on its longitudinal extension.

[0019] In one embodiment, the assembly has a first fixed body and a second fixed body, which are spaced apart from each other in a longitudinal direction. Preferably, a guide section configured as a screw and another guide section configured as a smooth shaft (especially the entire track) extend longitudinally from the first fixed body to the second fixed body, wherein a slider is arranged between the first and second fixed bodies and is movable longitudinally between the first and second fixed bodies by rotation of the guide section configured as a screw. This is naturally based on the operating state, in which the corresponding guide sections are arranged in their respective guide receiving parts. With this particularly advantageous assembly, the slider can reliably move between the two fixed bodies. This assembly is particularly advantageous for use in food production processes, for example, for implementing lifting platforms or for moving equipment fastened to the slider between two fixed bodies. Particularly preferred is that the slider has a mounting opening at which the equipment can be fastened by bolts. For example, the bolts can extend through the mounting opening and be screwed into or onto the equipment. The device can be used in the food production process, such as a robot, a holding arm, or similar equipment.

[0020] In one embodiment, the slider has a slider body with a longitudinally penetrating opening (the opening having an opening cross-section), wherein a guide unit is fastened to the slider body, the guide unit forming a guide receiving portion, wherein the cross-section of the guide receiving portion is aligned with the cross-section of the opening. The guide unit can be constructed, for example, as a guide member or slider portion as described above. Because the guide receiving portion is constructed by such a guide unit (which is manufactured as a component independent of the slider body and then fastened to the slider body to realize the slider), the slider body and the guide unit can be specifically manufactured for their respective purposes. For example, the slider body can be made of stainless steel, while the guide unit can be made of a sliding material. Generally, it is preferred that the slider body is made of a first material, and the guide unit is made of a second material. Generally, it is preferred that the guide unit is made of a sliding material.

[0021] In one embodiment, the slider has a rinsing opening on at least one side (which limits the slider in a transverse direction perpendicular to the longitudinal direction), from which a rinsing channel extends transversely to the guide receiving portion. By providing the lateral rinsing opening and connecting the guide receiving portion to the rinsing channel, the cleaning of the entire guide receiving portion can be further improved. Particularly preferred is that the rinsing opening and / or rinsing channel is spaced apart from the two longitudinal ends of the slider. Particularly preferred is that the rinsing channel merges into at least one (especially at least two adjacent) rinsing voids. Since the rinsing channel merges into at least one (preferably at least two) rinsing voids, cleaning fluid can be introduced into the rinsing voids through the rinsing channel. This is particularly advantageous for rinsing the rinsing voids. Generally, for any embodiment, it is particularly preferred that the rinsing voids or rinsing slots open at their two longitudinal ends respectively, so that cleaning fluid can enter the rinsing voids from their two longitudinal ends. In a particularly preferred embodiment with lateral rinsing openings and rinsing channels, cleaning fluid can be introduced not only from the longitudinal ends of the rinsing voids but also from the sides. Particularly preferred is that the flushing opening extends over at least 20%, particularly at least 30%, of the longitudinal extension length of the slider. This makes cleaning particularly easy. Generally, the flushing channel preferably merges into the guide receiver at a confluence point, wherein at this confluence point, in a vertical direction perpendicular to the longitudinal direction, the flushing channel has a net height that is 0.5 times, particularly at least 0.7 times, the net height of the guide receiver in that vertical direction; and / or, at least 0.2 times, particularly at least 0.3 times, particularly at least 0.5 times, of the entire extension length of the slider in that vertical direction. Generally, the slider also preferably has additional guide receivers and additional flushing openings, wherein the additional flushing openings and the flushing openings are disposed on two mutually disjointed sides of the slider, which respectively limit the slider in the aforementioned transverse direction. Accordingly, the slider may have an additional flushing channel that extends from an additional flushing opening to an additional guide receiving portion, and may be provided with other features as currently associated with the flushing opening, flushing channel and guide receiving portion.

[0022] The present invention also relates to the application of the components according to the invention for food production. For food production, at least one ingredient and / or at least one piece of equipment is transported by means of a slider. Here, the slider, together with the ingredient or equipment arranged thereon, moves relative to a track in a longitudinal direction (preferably only in the longitudinal direction). Particularly preferred is that, between two consecutive stages of application in which food is produced respectively, while the component is in operation, the component is cleaned with a cleaning solution. Preferably, the component is in continuous operation during and between the stages in which the corresponding food is produced, i.e., each of the predetermined guide sections of the track is continuously arranged in and held within the corresponding guide receiving portion of the slider. During each of the stages, food is preferably produced by moving the slider relative to the track in a longitudinal direction. Attached Figure Description

Detailed Implementation

[0025] Including Figure 1a , Figure 1b and Figure 1c Figure 1 illustrates one embodiment of component 1 according to the present invention using different schematic principles. Figure 1a A schematic top view of the components is shown. Figure 1b A cross-sectional view of the component is shown, in which the longitudinal direction X lies within the cross-sectional plane. Figure 1cAnother cross-sectional view of the assembly is shown, where the longitudinal direction X is perpendicular to the cross-sectional plane. Assembly 1 according to Figure 1 has a guide section comprising a guide segment 3 and a first additional guide segment 4 and a second additional guide segment 5. The additional guide segments 4 and 5 are each constructed as smooth circular shafts and are fixed to a first fixed body 6 by means of their first end and to a second fixed body 7 by means of their second end. Guide segment 3 is arranged between the two additional guide segments 4 and 5 and is constructed as a threaded screw. Guide segment 3 is rotatably supported on the two fixed bodies 6 and 7 by means of a rotary bearing 50. A slider 2 is also arranged between the two fixed bodies 6 and 7. In Figure 1, assembly 1 is shown in its operating state. The slider 2 (shown in more detail in Figure 2) has a guide receiving portion corresponding to each of the guide segments 3, 4, and 5, in which the corresponding guide segments 3, 4, and 5 are arranged in the guide receiving portion in the operating state shown in Figure 1. The additional guide sections 4 and 5 and the additional guide receiving portions are all constructed as smooth shafts or smooth guide receiving portions, and therefore do not have a stepped shape in the longitudinal direction. Currently, they even have the same cross-section in their longitudinal extensions. However, this is not the case for the guide section 3, which is constructed as a screw, and the corresponding guide receiving portion of the slider 2, because they are constructed as stepped in the longitudinal direction due to the threads provided on their outer sides. By rotating the guide section 3 about an axis extending parallel to the longitudinal direction X shown in FIG1, the slider 2 can be moved purely translationally in the longitudinal direction X between the fixed bodies 6 and 7. The guide portion (which provides additional guide sections 4 and 5 together with their corresponding guide receiving portions) prevents the slider 2 from rotating when the guide section 3, which is constructed as a screw, rotates about its axis (which coincides with the axis of the guide receiving portion corresponding to it and extends parallel to the longitudinal direction X). The slider 2 also has a fastening opening 20 through which the device can be fixed to the slider 2. Therefore, the slider 2 can be used as a moving stage that can move in the longitudinal direction X. The threads constructed on the outer side of guide section 3 are not explicitly shown in the figure. However... Figure 1b As shown, slider 2 overlaps with the extension of the screw due to its internal thread, which can only be achieved if the screw has an external thread. Through the combined action of the external thread of the guide section 3, which is constructed as a screw, and the internal thread of the corresponding guide receiving part of slider 2, the rotation of the screw, as described, enables slider 2 to move in the longitudinal direction. Figure 1c As shown in Figure 1, the guide receiving part of slider 2 has a flushing void, which allows for effective flushing or cleaning of the components in the operating state shown in Figure 1. The characteristics of the flushing void will be further described in detail below with reference to Figure 2.

[0026] Including Figure 2a , Figure 2b and Figure 2c Figure 2 schematically illustrates the slider 2 of the component according to Figure 1 using a different principle. Figure 2a A schematic perspective view of the slider is shown; Figure 2b A top view of the slider along the longitudinal direction is shown; Figure 2c A cross-sectional view of the slider is shown, the cross-sectional plane of which extends parallel to the longitudinal direction X. As can be seen from Figure 2, the slider 2 has a guide receiving portion 23 and first and second additional guide receiving portions 24, 25. Each guide receiving portion 23, 24, 25 has a net cross-section defined by a boundary wall surrounding the axis of the respective guide receiving portion 23, 24, 25, wherein the boundary wall has a plurality of stop sections 231, 241, 251, which are distributed around the axis of the respective guide receiving portion 23, 24, 25, wherein a flushing void 230, 240, 250 is provided between two adjacent stop sections 231, 241, 251, respectively. The stop sections 231 of the guide receiving portion 23 collectively form an internal thread, which is formed only by the stop sections 231 at angles, and the internal thread is discontinuous due to the flushing void 230, which is also from Figure 2c It is evident. Especially from Figure 2b As can be seen, the stop sections 231, 241, 251 and the rinsing clearance sections 230, 240, 250 of the guide receiving sections 23, 24, 25 are arranged in the following configuration: on the one hand, they are arranged symmetrically (i.e., evenly distributed) about the axis of the respective guide receiving sections 23, 24, 25; on the other hand, in the direction of rotation about this axis, two corresponding stop sections 231, 241, 251 are arranged side by side, and the corresponding rinsing clearance sections 230, 240, 250 are arranged between them relative to this direction of rotation. Here, the stop sections 231, 241, 251 and the rinsing clearance sections 230, 240, 250 each extend within an angular range, which relates to the direction of rotation about the axis of the respective guide receiving section 23, 24, 25. Figure 2bIt is evident that the angular range of the rinsing clearance portions 230, 240, and 250 roughly corresponds to the angular range of the corresponding adjacent stop sections 231, 241, and 251. Furthermore, it is also evident that the rinsing clearance portions 230, 240, and 250 are each constructed as rinsing channels, each having a bottom formed by the boundary walls of the corresponding guide receiving portions 23, 24, and 25. Therefore, the stop sections 231, 241, and 251, which are adjacent to and separated from the rinsing clearance portions 230, 240, and 250, can be connected to each other through the bottom of the rinsing clearance portions 230, 240, and 250. Relative to the aforementioned direction of rotation, the rinsing clearance portion 230 has a width that increases with distance from the axis in a direction perpendicular to the axis of the guide receiving portion 23 until it reaches its maximum value, and then decreases; while the rinsing clearance portions 240 and 250 of the other guide receiving portions 24 and 25 have substantially constant widths. Furthermore, it can be seen that the flushing voids 230 of the guide receiving section 23 each have a significant flushing void cross-section (currently exceeding 5mm). 2 The flushing clearance sections 240 and 250 of the other guide receiving sections have a significantly smaller flushing cross-section (less than 4 mm). 2 Overall, it is particularly advantageous for the present invention that the flushing opening of the guide receiver (whose stop section provides internal threads) is configured to be particularly large, especially larger than the flushing opening of the smooth guide receiver, because even if a screw with external threads is arranged in the guide receiver, these particularly large flushing openings of the guide receiver can easily achieve sufficient flushing.

[0027] The slider 2 shown in Figure 2 is constructed as a one-piece slider, made of a sliding material (currently a friction polymer). Figures 3 and 4 show embodiments of a separate guide unit 8, also made of the sliding material (currently a friction polymer), which is fastened to the slider body of the slider 2 according to an embodiment of component 1, and here can serve as a washable nut to receive the screw. This separate guide unit proves particularly advantageous because it allows for a very simple slider configuration that enables screw drive (as shown in the embodiment according to Figure 1), and furthermore, easy washing even when the nut and screw are engaged.

[0028] Figure 3 (including) Figure 3a and Figure 3b The schematic diagram illustrates an implementation of this guide unit. Figure 3a An oblique view of guide unit 8 is shown; Figure 3b A view of guide unit 8 along the longitudinal direction X is shown. Figure 4 (including...) Figure 4a , Figure 4b and Figure 4cAnother embodiment of this guide unit 8 is illustrated with several schematic diagrams. The guide units 8 shown in Figures 3 and 4 share a common feature: they are each made of a sliding material and have an assembly opening 80, by means of which they can be (e.g., by bolts) fixed to the slider body of the slider 2. Each guide unit 8 has a guide receiving portion 82, configured as a through-hole portion passing through the guide unit 8, which, in the implemented slider, constitutes the guide receiving portion of the slider. The corresponding slider body (not shown) has an opening that, when the guide unit is assembled, is arranged aligned with the guide receiving portion (or through-hole portion 82) so that the guide section of the track, configured as a screw, can extend through the through-hole portion (or guide receiving portion 82) and the opening of the slider body. The opening of the slider body is preferably larger than the net cross-section of the guide receiving portion 82, preferably at least 1.2 times, and especially at least 1.5 times, the net cross-section of the guide receiving portion 82. The guide units 8 shown in Figures 3 and 4 each have a stop section 821 and a flushing clearance portion 820. The difference lies in the fact that, in the guide unit according to Figure 3, the rinsing void is constructed as a rinsing groove, while in the guide unit 8 according to Figure 4, the rinsing void 820 is constructed as a through opening. The guide unit 8 according to Figure 3 has particularly high stability, while the guide unit 8 according to Figure 4 is particularly easy to rinse.

[0029] Figure 5 (including) Figure 5a , Figure 5b and Figure 5c The diagram illustrates another embodiment of component 1 according to the invention using different principles. Figure 5a An oblique view of component 1 is shown; Figure 5b The view of component 1 perpendicular to the longitudinal direction X is shown; while Figure 5cA cross-sectional view of component 1 is shown, with its cut-off surface extending perpendicular to the longitudinal direction X. The component shown in Figure 5 is in operation. Component 1 has two guide sections 4 and 5, each constructed as a smooth shaft (currently a circular shaft). Slider 2 has two guide receivers 24 and 25, each constructed to correspond exactly to one of its corresponding guide sections 4 and 5. Currently, and generally advantageously, guide sections 4 and 5 are constructed identically, as are guide receivers 24 and 25. The track of the component according to Figure 5, in addition to having guide sections 4 and 5 manufactured as independent components, also has a connecting member 9, through which guide sections 4 and 5 are connected to each other. The connecting member 9 has a bottom side through which it can be pre-fitted onto a flat surface of the structural element, wherein all sides of the connecting member other than the bottom side are inclined relative to the plane, so that cleaning fluid can flow down the connecting member particularly easily. Currently, and generally, it is particularly advantageous that the connecting member 9 has a bolt by which the connecting member can be fastened to the structural element, wherein the bolt is guided through an opening in the connecting member, and a sealing portion is provided between the opening and the bolt to prevent dirt from entering between the boundary of the bolt and the opening. Furthermore, according to the invention, it is generally preferred to provide a sealing portion between the connecting member 9 and each of the guide sections 4, 5 to effectively prevent contaminants from entering the space between the connecting member 9 and the guide sections 4, 5. In the embodiment according to FIG. 5, the guide receiving portions 24, 25 and the guide sections 4, 5 of the slider 2 are each smoothly constructed, so that the slider 2 can move along the track in the longitudinal direction X with very little friction. Therefore, the slider 2 is driven individually (e.g., by hand), unlike the embodiment shown in FIG. 1 which is configured to be driven by a screw. A particularly advantageous feature of the slider 2 according to the embodiment of FIG. 5 is that a rinsing opening 21 is provided on each lateral side, which limits the slider 2 in a lateral direction extending perpendicular to the longitudinal direction X, which is generally advantageous according to the invention. Figure 5a , Figure 5b and Figure 5c Referring to the visible flushing opening 21, and especially as described below with reference to Figures 6 and 7, which respectively illustrate corresponding embodiments of the slider of the assembly according to Figure 5, each flushing opening 21 has a flushing channel extending laterally in a component to the net cross-section of a corresponding guide receiver 24, 25, and converging into the net cross-section of the respective guide receiver 24, 25. This ensures particularly good flushability of the guide receivers, and consequently, particularly good flushability of the entire assembly, because the cleaning fluid can enter the flushing channel 210 through the flushing opening 21, and from there enter the corresponding guide receiver 24, 25, and flow on the guide sections 4, 5, thus achieving the corresponding cleaning.

[0030] Figure 6 (including) Figure 6a , Figure 6b and Figure 6c Figure 7 shows one embodiment of the slider 2 suitable for component 1 according to Figure 5. Figure 7a and Figure 7b The diagram shows another embodiment of the slider 2 applicable to component 1 according to Figure 5. The difference between the different embodiments lies in the configuration of the flushing voids of their guide receiving portions 24, 25. Figure 6a The image shows a perspective view of a first embodiment of slider 2; Figure 6b The image shows a top view of slider 2 perpendicular to the longitudinal direction X; while Figure 6c The image shows a cross-section that extends with its cross-sectional plane perpendicular to the longitudinal direction X. Figure 7a The image shows a top view of the second embodiment of slider 2, perpendicular to the longitudinal direction X; Figure 7b The figure shows a cross-section of the second embodiment, the cross-section of which extends perpendicular to the longitudinal direction X. As can be seen from the figures, in each embodiment, the flushing opening 21 extends its longitudinal length by more than 30% and less than 70%, especially less than 60%, especially less than 50% of the longitudinal length of the slider 2, which is generally advantageous according to the invention. The flushing channels 210 each have a net cross-section whose longitudinal length extends from the flushing opening 21 to the guide receiving portions 23, 24, extending at least 20%, especially 30%, preferably less than 70%, especially less than 60%, especially less than 50% of the longitudinal length of the slider 2, which is generally advantageous according to the invention. The flushing channels 210 merge into the corresponding guide receiving portions 24, 25, wherein, generally advantageous according to the invention, the flushing channels merge into at least two flushing cavities of the corresponding guide receiving portions 24, 25, especially exactly two flushing cavities. The slider 2 also has a recess 22, which is configured to receive a section of the connecting member 9, currently used to receive the bolt of the connecting member 9. The recess 22 extends through the slider 2 in the longitudinal direction X, and in the operating state, when the connecting member 9 is located within the longitudinal extension of the slider 2, the wall of the recess 22, constructed by the slider 2, is positioned at a distance greater than 2 mm, especially greater than 3 mm, especially greater than 4 mm from the connecting member at any position, thus ensuring reliable and effective cleaning of the component 1 at all times.
