Description

Technical area

[0001] The present invention relates to a clamp holder for fastening plate-shaped separating elements in a grid-shaped cable tray. Furthermore, the invention relates to a cable duct system comprising a grid-shaped cable tray, a plate-shaped separating element, and a plurality of corresponding clamp holders. Furthermore, the invention relates to a container processing machine comprising a corresponding cable duct system. State of the art

[0002] In complex machines and systems, a multitude of different cable connections are necessary to connect and link individual components. Cable ducts or cable trays are used for this purpose. Cable trays are elongated, ladder-like devices in which cables can be laid.

[0003] In this context, it is known from the prior art to form corresponding cable trays from longitudinally and transversely extending elements. The cable trays are then designed in a grid-like manner or as grid trays. Such a grid tray is known, for example, from WO 2009 / 007020 A1.

[0004] In certain cases, it is desirable to separate the cables arranged in the cable tray into groups. Plate-shaped separators are generally used as separating elements, which are attached to the cable tray via holders. Typically, the holders are screwed to the cable tray. Holders that can be attached without tools are also known in the prior art. For example, DE 197 26 500 B4 discloses a separating device for a grid-shaped cable tray. The holders are made of plastic and have recesses formed in the plastic material so that they can be snapped onto transversely extending rods of the cable tray. Description of the invention

[0005] The invention is based on the object of providing an improved clamp holder for fastening plate-shaped separating elements in or on a grid-shaped cable tray. Furthermore, the invention is also an object of providing a cable duct system with a plurality of corresponding clamp holders and a container handling machine with a corresponding cable duct system.

[0006] These objects are achieved by the subject matter of the independent claims. Further possible embodiments of the invention are specified in particular in the dependent claims.

[0007] The solution according to the invention consists, in particular, in providing a clamp holder for fastening plate-shaped separating bodies in a grid-shaped cable tray, which is formed by a number of longitudinally extending rod elements arranged at a distance from one another and transversely extending rod elements. The clamp holder has a fastening area for tool-free, form-fitting fastening to the rod elements. Furthermore, the clamp holder has a clamping area extending upward from the fastening area. The clamping area has two opposing clamping jaws.

[0008] According to the invention, the clamp holder is formed in two parts, consisting of two at least substantially, in particular completely identical, clamp holder elements. Furthermore, according to the invention, the two clamp holder elements can be releasably connected to one another. Preferably, the two clamp holder elements can be locked together.

[0009] The clamp holder is generally a fastening element that is designed to fix or secure plate-shaped separating bodies in the grid-shaped cable tray.

[0010] The plate-shaped separators are plate-shaped elements designed to separate cables from one another within the grid-shaped cable tray. The plate-shaped separators can therefore be inserted into the cable tray to separate or insulate different cable segments or strands from one another.

[0011] The cable tray is a system of interconnected rods designed to create a space for cables.

[0012] The fastening area is generally the part of the clamp holder that is designed to be connected to the cable tray or its rod elements. The fastening area is designed in such a way that it can be attached to the rod elements without the need for tools and with a form-fitting connection. This means that the fastening is ensured by the shape of the components themselves, and preferably no additional fastening device is required. The use of a tool is not necessary for fastening.

[0013] The clamping area is generally the part of the clamp holder that serves to fix or clamp the plate-shaped separator. The clamping jaws are designed to clamp the plate-shaped separator between them and thus hold it in place. The clamping jaws are designed to grip the separator on both sides and thereby hold it in position.

[0014] Since the clamp holder according to the invention is formed from two identical components, namely the clamp holder elements, the clamp holder can be manufactured using cost-effective manufacturing processes. Instead of a complex mold, a simpler mold can be used for production.

[0015] By snapping the two clamping elements together, a tool-free and simple connection is possible. This results in quick and easy assembly. This makes it possible to produce a clamping holder with a complex geometry from two clamping elements with a simple geometry.

[0016] According to an advantageous development of the invention, each of the clamping elements has one of the clamping jaws. Furthermore, the two clamping elements together form the fastening area.

[0017] The fastening area with which the clamp holder can be fastened to the rod elements of the cable tray is thus formed from the combined structures of both clamp holder elements.

[0018] Preferably, the clamp holder can be divided into two clamp holder elements along a plane. This plane extends at least substantially parallel to the main plane of extension of the two clamping jaws. In other words, the plane extends at least substantially parallel to the plate-shaped separating body received between the clamping jaws.

[0019] According to an advantageous development of the invention, the two clamping elements are designed to be slidable into one another. After sliding into one another, the two clamping elements can be locked together by means of a snap-in connection.

[0020] The two clamping elements are designed to be slid into one another. For example, the clamping elements can have guides that allow the clamping elements to slide over one another and be connected precisely. As soon as the clamping elements are fully slid into one another, they lock together via the snap-in connection. The snap-in connection ensures that the two clamping elements reach a stable end position. In the stable end position, the clamping elements remain securely connected to one another, preferably without the need for additional fastening elements. Irrespective of this, the snap-in connection is preferably arranged in the fastening area of ​​the clamping element.

[0021] In an advantageous development of the invention, the two clamping holder elements can be pushed into one another along a direction parallel to the main extension direction of the clamping jaws.

[0022] In particular, the two clamping elements are designed to be slidable into one another along a direction parallel to the longitudinally extending rod elements. This direction is perpendicular to the direction in which the clamping jaws exert a clamping force on the plate-shaped separating elements. This design prevents the two clamping elements from accidentally separating from one another.

[0023] The solution according to the invention further consists in providing a clamp holder for fastening plate-shaped separating bodies in a grid-shaped cable tray, which is formed by a number of longitudinally extending rod elements arranged at a distance from one another and transversely extending rod elements. The clamp holder has a fastening area for tool-free, form-fitting fastening to the rod elements. Furthermore, the clamp holder has a clamping area extending upward from the fastening area. The clamping area has two clamping jaws.

[0024] According to the invention, the fastening region is designed for the positive fastening of rod elements of different diameters. The fastening region has a first fastening structure for rod elements with a first diameter and a second fastening structure for rod elements with a second diameter. The fastening structures can, in particular, be narrow sections.

[0025] The aspects and definitions described above also apply to this clamp holder. This clamp holder can preferably also be constructed in two pieces. Alternatively, the clamp holder can be constructed in one piece, in particular as a single-piece molded piece.

[0026] A fastening structure is generally a structure or geometry formed in the fastening area that is designed to fix or hold rod elements. The fastening structure can, in particular, be a constriction or bottleneck whose contour fits precisely around rod elements of a specific diameter. The bottleneck thus creates a positive connection that securely holds the rod element. More generally, the bottlenecks provide a tight fit for the rod elements due to their narrowed shape. The rod elements can thus be clamped into the bottlenecks.

[0027] In general, the first and second fastening structures offer the possibility of attaching rod elements with a smaller and a larger diameter, respectively. This makes the clamp holder universally applicable to a variety of cable trays. This makes it possible to use one type of clamp holder in various cable tray systems, which differ primarily in the diameter of the rod elements.

[0028] According to an advantageous development of the invention, the fastening area has a recess with an insertion opening and at least one constriction.

[0029] The recess generally serves as a receiving area for the rod elements, which are securely fastened in the narrow area. The rod elements can be inserted into the recess through the insertion opening. The insertion opening is designed so that the rod elements can be inserted into the recess, preferably without resistance.

[0030] At least one constriction is then formed within the recess, which, as a narrowed passage, allows for the positive holding of the rod elements. In particular, there may be several constrictions designed for rod elements of different diameters.

[0031] In an advantageous development of the invention, the recess is designed such that the rod elements are first inserted into the recess in a first direction through the insertion opening. Subsequently, the rod elements are moved in a second direction, at least substantially perpendicular to the first direction, into the at least one constriction.

[0032] This has the advantage that the rod elements cannot be released from the mounting area by moving in one direction. Overall, this allows for secure fastening of the rod elements in the recess.

[0033] In an advantageous development of the invention, the second constriction has a smaller diameter than the first constriction. The first constriction is arranged between the insertion opening and the second constriction.

[0034] The second constriction is thus intended for the attachment of rod elements with a smaller diameter, while the first constriction is designed for the attachment of larger rod elements. Due to the described arrangement, when inserting the rod elements, the larger constriction is first passed before the rod element, if it has a smaller diameter, can be clamped into the smaller constriction located further inside. The design thus allows rod elements of different sizes to be securely and positively fixed.

[0035] According to an advantageous development of the invention, the at least one constriction is shaped such that, after being transferred into the constriction, the rod element is mechanically fixed in the direction opposite to the second direction. In other words, the shape and / or structure of the constriction is such that it prevents the rod elements from moving opposite to the second direction. This prevents the rod element from shifting or loosening during use or under load, thus providing a secure and reliable mounting.

[0036] Preferably, the recess is designed symmetrically with a left constriction and a right constriction. The recess is designed symmetrically when viewed from above onto the clamping jaw. The symmetrical design means that the two constrictions are identical and positioned opposite one another within the recess. Rod elements, particularly those of the same diameter, can be fixed either at the left constriction or the right constriction.

[0037] If this idea is extended to include a first constriction and a second constriction, it is also conceivable for the recess to have a first left constriction and a second left constriction, as well as a first right constriction and a second right constriction. Alternatively, the first constriction can be a common constriction.

[0038] The symmetrical design of the recess is particularly related to the two-part design of the clamp holder with two different clamp holder elements.

[0039] In an advantageous development of the invention, the fastening area has a further recess for receiving rod elements which are aligned perpendicular to the rod elements fixed in the recess.

[0040] For example, transversely extending rod elements can be arranged in the recess, and longitudinally extending rod elements can be arranged in the further recess. This makes it possible to arrange the clamp holder simultaneously on longitudinally extending rod elements and transversely extending rod elements. In addition to reliable fastening, this also provides anti-twist protection, as the clamp holder is held on intersecting rods.

[0041] Preferably, the further recess extends at least substantially along the entire length of the fastening region of the clamp holder.

[0042] The recess, in turn, preferably extends in the direction of the width of the fastening area.

[0043] In an advantageous development of the invention, the clamping jaws are designed to be resilient. The clamping jaws are particularly designed to elastically deflect outward upon insertion of the plate-shaped separating body in order to accommodate the plate-shaped separating body. The plate-shaped separating body is then clamped in the intended position by the restoring force of the clamping jaws.

[0044] The spring-loaded design of the clamping jaws allows them to move elastically outward when the plate-shaped separator is inserted. This allows for flexible opening of the clamping jaws to create sufficient space for the plate-shaped separator.

[0045] Furthermore, the flexibility allows for the inclusion of various plate-shaped separators with different diameters. Overall, the spring-loaded clamping jaws allow for easy and quick insertion of the plate-shaped separator and reliable retention of the clamping element in the desired position.

[0046] According to an advantageous development of the invention, the clamping jaws have at least one, preferably several, in particular linear, clamping points at which the clamping jaws are designed to be close to one another.

[0047] The clamping jaws are therefore not formed continuously in a straight plane, but rather have at least one, preferably several, defined, particularly linear, clamping points. The arrangement of the clamping points ensures that at certain points or lines, a particularly close contact surface exists between the clamping jaws and the plate-shaped separating body. At other points, however, a gap is formed between the clamping jaws and the plate-shaped separating body.

[0048] By using several linear clamping points instead of one flat clamping point, even separating bodies that are not completely flat can be accommodated.

[0049] Furthermore, by providing multiple clamping points, a multi-stage clamping of the plate-shaped separator can be implemented. A first clamping point then serves as the first, particularly linear, contact surface for the plate-shaped separator, while the second clamping point additionally secures the plate-shaped separator, for example, when the plate-shaped separator is fully inserted.

[0050] In an advantageous development of the invention, the clamping jaws each have an insertion slope in their upper region.

[0051] The insertion bevel is preferably a tapered surface that forms the upper part of the clamping jaw. The beveled surface allows the plate-shaped separator to be inserted into the clamping jaws more easily than a flat surface.

[0052] Overall, the design of the clamping jaw allows for smooth and easy insertion of the separator. This leads to a faster assembly process and prevents damage to the clamp holder or the plate-shaped separator.

[0053] If the clamping jaw has several clamping points, one of the clamping points is preferably arranged at the top and thus close to the insertion slope and a second clamping point is arranged in a lower position.

[0054] According to an advantageous further development, the clamp holder is made of metal.

[0055] On the one hand, metal gives the clamp holder high strength and stability, ensuring long-term use. Especially when the plate-shaped separator is also made of metal, the clamp holder and the plate-shaped separator are suitable for shielding currents and voltages in conductor circuits separated by the separators. This prevents, in particular, electromagnetic interference and noise.

[0056] The clamp holders can therefore serve as part of a metallic shield.

[0057] According to an advantageous further development, the clamp holder is designed as an injection-molded part, in particular as a two-part injection-molded part.

[0058] The injection molding process enables economical mass production of the clamp holder. This is particularly possible because the clamp holder is constructed in two parts.

[0059] The solution according to the invention further consists in providing a cable duct system. The cable duct system has a grid-shaped cable track for guiding cables. Furthermore, the cable duct system has at least one plate-shaped separating body for spatially separating and / or shielding cables within the grid-shaped cable track. Furthermore, the cable duct system has a plurality of the previously described clamp holders, which are designed to fasten the plate-shaped separating body, in particular detachably, to the grid-shaped cable track.

[0060] Since the clamp holders are the clamp holders described above, all aspects and advantages of the clamp holders can also be transferred to the cable duct system.

[0061] The overall result is a cable duct system that is simple to construct and quick to install and adapt.

[0062] The solution according to the invention further consists in providing a container treatment system with the cable duct system described above. Since the clamp holders are the clamp holders described above, all aspects and advantages of the clamp holders can be adopted here.

[0063] A container processing plant is, in general, a plant for processing containers. For example, the container processing plant can be a plant for manufacturing, filling, labeling, and / or assembling and packaging the containers in groups. Furthermore, the container processing plant can comprise a plurality of container processing machines. For example, this can be a container manufacturing machine, a filling machine, a closing machine, a cleaning machine, a labeling machine, a packaging machine, and / or a palletizing machine.

[0064] The individual container processing machines are then preferably connected to one another via at least one cable duct system. Furthermore, corresponding cable duct systems can be provided within the container processing machines.

[0065] The confined and complex machine environment of the container processing plant can be efficiently connected using the cable duct systems described above. Furthermore, the cable duct systems described above can provide sufficient protection against the conditions prevailing in the container processing plants. Short description of the drawings

[0066] The various and exemplary features described above can be combined with one another according to the invention, provided this is technically reasonable and suitable. Further features, advantages, and embodiments of the invention will become apparent from the following description of exemplary embodiments and from the figures.

[0067] The figures used to explain the embodiments show: Fig. 1 is a schematic representation of a clamp holder according to the present invention; Fig. 2 the in Fig. 1 shown clamp holder is fixed to a grid-shaped cable tray; Fig. 3 a cable duct system according to the invention with the grid-shaped cable tray, several clamp holders and a plate-shaped separating body; Fig. 4 a side view of a Fig. 3 clamp holders used; and Fig. 5 a schematic representation of a clamp holder according to a second embodiment of the present invention. Ways to implement the invention

[0068] Fig. 1 shows a clamp holder 100. The clamp holder 100 has a lower fastening area 110 and an upper clamping area 120. The clamping area 120 is essentially formed by a first clamping jaw 121 and a second clamping jaw 122.

[0069] At the upper end of each of the clamping jaws 121, 122 there is an insertion bevel 123. The insertion bevel 123 facilitates the insertion of a Fig. 3. The separating body 300 is pushed from above between the two clamping jaws 121 and 122. The two clamping jaws 121 and 122 form several clamping points 124.

[0070] As particularly in Fig. 4, a close contact is established between the plate-shaped separating body 300 and the two clamping jaws 121 and 122 at the clamping points 124. Due to the design with clamping points 124 and the insertion slope 123, the two clamping jaws 121, 122 have a wave shape or zigzag shape when viewed from the side. This is particularly evident in Fig. 4 can be clearly seen.

[0071] The fastening area 110 has a recess 114 and a further recess 115. As shown in particular in Fig. 2, the further recess 115 serves to accommodate longitudinally extending rod elements 210 of the grid-shaped cable track 200. The recess 114, on the other hand, serves to accommodate transversely extending rod elements 220. Overall, longitudinally extending rod elements 210 and transversely extending rod elements 220 can thus be fastened in the fastening area 110.

[0072] As in Fig. 1, the recess 114 has an insertion opening 113 for inserting the transversely extending rod elements 220. Furthermore, the recess 114 has a first fastening structure 111 formed in the form of a first constriction 111a. Fig. 2, the transversely extending rod element 220, designated by reference numeral 220, can be arranged or is arranged in the first constriction 111a. Behind the first constriction 111a, there is a further, second constriction 112a serving as the second fastening structure 112. The second constriction 112a is narrower than the first constriction 111a. Consequently, the second constriction 112a is suitable for accommodating rod elements 220 with a smaller diameter. Overall, rod elements 220 with different diameters can thus be accommodated in the fastening region 110.

[0073] As in Fig. 1, the recess 114 is symmetrical. In particular, the recess 114 is symmetrical when viewed from above onto the clamping jaws 121 and 122, i.e., when viewed along the direction of extension of the rod elements 220. In its symmetrical configuration, the recess 114 has two first fastening structures 111 or first constrictions 111a and two second fastening structures 112 or second constrictions 112a. This can be seen in particular from the fact that in Fig. 1 the left narrow passages 111a and 112a and in Fig. 2, the right-hand constrictions 111a and 112a are provided with reference numbers. Mounting on the rod elements 220 can thus be done on the left or right.

[0074] The symmetrical design of the recess 114 is particularly related to the fact that the Fig. 1 is formed from two identically designed clamping elements 101 and 102. The individual clamping elements 101 and 102 are in Fig. 4 marked.

[0075] The two clamping elements 101 and 102 can be locked together via a locking structure 103. The two clamping elements 101 and 102 are designed to be slidable into one another along a direction parallel to the main extension direction of the clamping jaws 121, 122. Fig. The clamp holder 100 shown in Figure 4 is therefore divided into two parts: a left clamp holder element 101 and a right clamp holder element 102.

[0076] As in Fig. As can be seen in Figure 1, the clamp holder 100 has a stiffening element 126 extending from bottom to top. The stiffening element 126 is designed, in particular, as a rib extending from bottom to top. The stiffening element 126 preferably connects the insertion slope 123 to the recess 114.

[0077] The recess 114 can further be surrounded by a stiffening collar 127. The stiffening collar 127 is preferably connected to the stiffening element 126. The stiffening collar 127 is formed so as to protrude from the fastening region 110.

[0078] In Fig. 3 shows a cable duct system comprising the grid-shaped cable tray 200 with corresponding rod elements 210 and 220. Also shown are two clamp holders 100, which are attached to a common longitudinally extending rod element 210 and two different transversely extending rod elements 220.

[0079] The two clamp holders 100 hold the plate-shaped separating body 300. The plate-shaped separating body 300 is as in Fig. 4 shown arranged between the two clamping jaws 121 and 122.

[0080] As in Fig. As can be seen in Figure 4, the plate-shaped separating body 300 has reinforcement grooves 310. Thanks to the reinforcement grooves 310, the plate-shaped separating body 300 can be made thin while still being sufficiently stable.

[0081] Since the clamp holder 100 has clamping points 124 and points between the clamping points 124 where no clamping is present, it is also suitable for receiving the plate-shaped separating bodies 300 with reinforcement grooves 310. The reinforcement grooves 310 are then located in areas of the clamp holder 100 where no clamping point 124 is formed.

[0082] In addition, an edge 320 of the plate-shaped separating body 300 can be used to provide resistance to the removal of the plate-shaped separating body 300 from the clamp holder 100. Thus, the plate-shaped separating body 300 can be held particularly securely in the clamp holder 100.

[0083] Fig. Figure 5 shows a second embodiment of a clamp holder 100 according to the present invention. The clamp holder 100 is similar in its function and basic structure to the clamp holder shown in Figures Fig. 1 to 4. The described details are correspondingly based on the clamp holders 100 shown in Fig. 5 shown clamp holder 100 transferable.

[0084] In particular, the clamp holder 100 in Fig. 5 also has a fastening region 110 with a first fastening structure 111 formed as a first constriction 111a and a second fastening structure 112 formed as a second constriction 112a. Both constrictions 111a and 112a are formed in the recess 114a, which is accessible via the insertion opening 113.

[0085] The fastening area 110 also has the further recess 115, which serves to accommodate longitudinally extending rod elements 210 of the grid-shaped cable tray 200. Thus, the fastening area 110 can also be attached to longitudinally extending rod elements 210 and transversely extending rod elements 220.

[0086] The clamp holder 100 has a single first clamping jaw 121 and, for example, two second clamping jaws 122a in the clamping area 120. In particular, the first clamping jaw 121 and the second clamping jaws 122a are not positioned opposite each other. However, it would also be conceivable in principle for only a second clamping jaw 122 to be formed.

[0087] In contrast to the Fig. The clamp holder 100 shown in Figures 1 to 4 is the one shown in Fig. The clamp holder 100 shown in Figure 5 is formed in one piece. The clamp holder 100 is, in particular, formed in one piece by primary molding. The clamp holder 100 is preferably designed such that it can also be manufactured by injection molding, particularly due to the modified clamping area 120.

[0088] It should be noted that the features of the invention described with reference to individual embodiments or variants, such as the type and design of the individual components as well as their precise dimensions and spatial arrangement, may also be present in other embodiments, unless otherwise stated or technically prohibited. Furthermore, such features of individual embodiments described in combination do not necessarily have to be implemented in a given embodiment.
