Description
Technical Field
The present application relates to a turning unit according to the preamble of claim 1.
Background
From the catalog "Transfersystem TS plus" (order number R999000395; stages 2017-08) of bosheles, a combination for a conveying system is known, with which a conveying system using a conveyor chain can be constructed in particular. The turning point of the conveyor system comprises two parallel turning elements, which are each guided to a conveyor chain running round. The straight sections of the conveyor system can be implemented, for example, according to EP 1188,693 B1, wherein they comprise in particular straight section profiles which are produced integrally from aluminum by an extrusion process. The curve uses the section bar as a carrier bar, wherein the section bar is curved according to the desired curve line. During this bending, it can occur that the first guide for driving the preceding section of the conveyor chain conveying the articles is deformed. This can interfere with the operation of the conveyed article on the conveyor system.
In the known conveying system, two different types of conveyor chains are used, namely a flat chain and a accumulating roller chain. EP 1,188,693 B1 shows a section profile for a flat chain. However, in the context of the problems mentioned, the accumulation roller chain is particularly critical, since it is not well guided.
Disclosure of Invention
An advantage of the application is that the first guide of the conveyor chain can be manufactured accurately and cost-effectively. The main dimensions of the known conveyor system can be preserved here, so that the turning element according to the application can be easily used inside the above-mentioned assembly parts for conveyor systems.
According to claim 1, it is proposed that the first guide element is entirely formed by a separate guide assembly, which is fastened to the carrier profile. The turn line is preferably curved circularly. The turn line preferably extends in a plane. In addition to the carrier profile, the second guide can comprise at least one sliding profile made of plastic, which is held on the carrier profile, respectively, wherein the return section of the conveyor chain is supported on the at least one sliding profile. The carrier profile is preferably produced by an extrusion process, wherein it is bent into the desired curve shape after the extrusion process. The turning assembly is preferably manufactured into the desired turning shape without bending, most preferably by means of a chip-forming and/or die-casting process.
The mentioned conveyor system preferably comprises two conveyor chains extending in parallel at a distance, wherein correspondingly two turning units extending in parallel at a distance are provided. It will be appreciated that the two turning units have different turning radii, which differ by the parallel spacing.
Advantageous developments and improvements of the application are given in the dependent claims.
Can set up: the guide assembly comprises a first guide body and a separate second guide body, which each extend in a curved manner according to a curve, wherein they form opposite guides for the conveyor chain in the radial direction relative to the curve. Thereby simplifying the manufacture of the guide assembly. In particular, the first and/or the second guide body can be produced by a plastic injection molding process. The first guide body preferably forms a guide for the radially outer part of the conveyor chain, wherein the second guide body forms a guide for the radially inner part of the conveyor chain. The first and/or the second guide body, respectively, preferably extend along the turning line with a substantially constant cross-sectional shape. The first and/or the second guide body can each have a split and/or a thread for a fastener, in particular a screw.
Can set up: the first and/or the second guide body are each integrally formed along the entire length of the turn line. The turning unit can thus be assembled particularly simply. It is conceivable that the first and/or the second guide body is constructed in multiple pieces. This is considered especially when the turn line has a large radius or when the turn line is particularly long.
Can set up: the first guide body and/or the second guide body are/is each made entirely of plastic. The conveyor chain can therefore run directly on the first or second guide body with low friction. Separate sliding profiles are not necessary.
Can set up: the first guide body has a flat bottom surface which is arranged parallel to the following plane: the line of curvature extends in the plane, wherein the first guide body rests with its bottom surface directly against the support profile. This embodiment is particularly space-saving in the vertical direction, so that the turning element can be easily implemented with the same main dimensions as the known section bar. Furthermore, the flat bottom surface or the associated flat top surface on the support profile can be produced particularly simply. The support profile preferably has a flat top surface which rests on the bottom surface of the first guide body.
Can set up: the first guide body protrudes radially inward relative to the pivot line and/or radially outward relative to the pivot line beyond the support profile, wherein the first guide body is fastened there to the respectively associated undercut groove, wherein the undercut groove is arranged on the radially inner or radially outer side wall of the support profile. The known section profiles have similar undercut grooves on their side walls, for example for fastening lateral guides for conveying articles. Furthermore, these undercut grooves provide sufficient active surfaces to fasten the guide assembly, in particular the first guide body, thereto. Preferably, the first guide body protrudes beyond the carrier both radially inward and radially outward, wherein it is fastened on both sides mentioned on the undercut groove. The undercut groove is preferably formed directly from the cross-sectional shape of the carrier profile, wherein the undercut groove is most preferably T-shaped when viewed in cross-section.
Can set up: the flat bottom surface of the first guide body extends in the radial direction with respect to the line of curvature over the entire width of the first guide body, wherein at least one separate fastening element is provided, which is attached to the bottom surface, wherein the fastening element is fastened to the first guide body, wherein the at least one fastening element is fastened in each case to the undercut groove. Alternatively, it is conceivable for the fastening element to be embodied integrally with the first guide body. The claimed embodiments have the following advantages: in the production of guides for conveyor chains, it is also possible to use a completely flat bottom surface, i.e. for fastening the respective blank on a milling machine for the production of the guide in a cutting-processing manner. The guide for the conveyor chain can thus be manufactured particularly precisely. Preferably, a plurality of fasteners are provided, most preferably evenly distributed along the turning line. Preferably, the plurality of fasteners are disposed on the first guide radially inward and radially outward. Preferably, a plurality of mutually identical fastening elements is provided, so that said fastening elements can be produced cost-effectively in large numbers.
Can set up: the second guide body directly rests on the first guide body and is fastened thereto, wherein the second guide body does not contact the support profile. The first guide body and the second guide body thus form a preassemblable guide assembly which can be fastened as a whole to the carrier profile. The corresponding final assembly is preferably only performed when the conveyor system is constructed. In contrast, the guide assembly can already be preassembled in advance, so that the final assembly of the conveyor system can be carried out particularly quickly. The second guide body is preferably screwed to the first guide body.
A section bar can be provided, which is made of aluminum, wherein the section bar is constructed in one piece, wherein the section bar extends along a straight line with a constant cross-sectional shape, wherein the section bar is mounted on the end face in the direction of the curve to the support bar and the guide assembly, wherein the section bar extends further in tangential alignment with both the first guide and the second guide. A corresponding section bar is known, for example, from EP 1188,693 B1. An advantage of the application is that such known road section profiles can be used continuously in a dimensionally unchanged manner. The road section profile can likewise be equipped with the already mentioned sliding profile.
Can set up: the at least one fastening body is fastened both to the associated first guide body and to the associated carrier profile and to the associated section profile. The last-mentioned fastening body thus has both functions. The fastening body connects the first guide body to the carrier profile, wherein the fastening body also connects this component to the road section profile. This results in a particularly inexpensive turning element which can be assembled simply and quickly.
It is to be understood that the features mentioned above and yet to be explained below can be used not only in the respectively given combination, but also in other combinations or alone without leaving the framework of the application.

fig. 1 is a perspective view of a conveyor system with two turning units according to the application; and
fig. 2 is a perspective view of the turning unit according to fig. 1.
Detailed Description
Fig. 1 shows a perspective view of a conveyor system 60 with two turning units 10 according to the application. In each of the turning units 10, a conveyor chain 61 runs around in a circulating manner, which is in each case in motion by means of an associated drive assembly 62. Two conveyor chains 61 extend parallel to one another, wherein the conveyor chains can carry conveyed articles 63. The conveyed article 63 comprises a workpiece carrier, such as a pallet. The current turn runs along a circular turn line 13 which extends over 90 °. Alternatively, a turning angle of 180 ° or any other turning angle is possible. At the two opposite ends of the turning line 13, straight sections are each joined tangentially. The two straight sections each comprise two parallel section profiles 15, which are each implemented, for example, according to EP 1,188,693 B1. The entire content of EP 1188,693 B1 is cited and becomes the subject of the present application. The straight section bars 15 are each made of aluminum, wherein the section bars are produced by an extrusion process. On these straight section bars, sliding or guide bars are attached, see EP 1188,693b1.
The two steering units 10 are fixedly connected to one another by a plurality of connecting struts 65, wherein the connecting struts 65 are each oriented in the radial direction 14 relative to the steering line 13.
Furthermore, it is to be noted that two opposing lateral guides 64 for conveying the articles 63 are preferably fastened to an undercut groove (number 24 in fig. 2) on the carrier profile, wherein the undercut groove continues in alignment on the section profile 15.
Fig. 2 shows a perspective view of the turning unit 10 according to fig. 1. Here, the road section contour (number 15 in fig. 1) is removed, so that the cross-sectional shape of the carrier profile 20 and the guide assembly 30 is visible.
The carrier profile 20 extends along a turn line (number 13 in fig. 1) with a constant cross-sectional shape. The load-bearing profile is manufactured from aluminium by means of an extrusion process. After extrusion, the carrier profile 20 is bent from a straight shape into a bent shape corresponding to a turn line.
The outer edges of the cross-sectional shape are substantially rectangular in configuration. The outer edge having a radially inner and radially outer side wall 21 with respect to the turn line; 22. the side walls are each configured linearly as seen in cross section, wherein the side walls each have an undercut groove 24, which is configured T-shaped as seen in cross section. The top surface 23 facing the guide assembly 23 is configured flat, wherein the respective plane is arranged parallel to the following plane: the turn line extends in said plane. The carrier profile has a closed cavity on the inside, which constitutes a second guide 12 for the return section of the conveyor chain. There, a projection, which protrudes in particular inwards, is provided for receiving a sliding profile (not shown) made of plastic, which is known from EP 1,188,693 B1.
The guide assembly 30 rests with its flat bottom surface 33 directly against the top surface 23 of the support profile 20. The guide assembly constitutes a first guide 11 for a preceding section of the conveyor chain. The first guide 11 is open upwards so that the conveyor chain can protrude there from the guide assembly 30 to carry conveyed articles.
The guide assembly 30 includes first and second guide bodies 31;32, which are each integrally constructed along the entire length of the turn line, wherein the guide bodies are made of plastic. The guide bodies are manufactured in a separate cutting process and/or as injection-molded parts according to their curved final shape, so that no bending process is required. First and second guide bodies 31;32 each have a substantially constant cross-sectional shape along the turn line.
The first guide body 31 forms a flat bottom 33, wherein the flat bottom extends in the radial direction (number 13 in fig. 1) over the entire width of the first guide body 31. Furthermore, the first guide body 31 constitutes a guide for the radially outer part of the conveyor chain. The second guide body 32 constitutes a complementary radially inner guide for the conveyor chain. The second guide body is firmly connected to the first guide body 31, wherein the second guide body is screwed to the first guide body, in particular by means of a screw pin 34.
The first guide body 31 projects beyond the carrier profile 20 both radially inwards and radially outwards. There, a plurality of square fasteners 41;42;43 are fastened to their flat bottom surfaces 33, which are each located against an associated inner or outer side wall 21 of the carrier profile 20; 22. A fastener 41;42;43 are screwed on the one hand to the first guide body 31. The fastening element is furthermore penetrated in the horizontal direction by a screw pin 45 which is screwed into an associated hammer nut 44 which in turn engages in the above-mentioned undercut groove 24. This type of fastening is carried out on the first and second guide 11;12 requires very little installation space in the vertical direction. The corresponding dimensions are fixedly predefined by the section profile known from EP 1188,693 B1, since this should be used in a constant manner. Thus, the fastener 41;42;43 are arranged laterally beside the carrier profile 20. There is sufficient installation space there, and furthermore an undercut groove 24, which is already present there, can be used, to which the lateral guide (number 64 in fig. 1) is also fastened.
Note also that two fasteners 42;43, which are configured larger than the fastener 41. The two fastening elements are arranged in the joint between the carrier profile 20 and the road section profile 15, wherein the two fastening elements are connected to the two profiles 20;15 is screwed. In both cases, undercut grooves 24 are used for this purpose.
Note, furthermore, that the recess 35 on the end face of the first guide body 31 is adapted to the road section profile (number 15 in fig. 1) with a small play. Thereby, the orientation of the desired alignment between the guide assembly 30 and the road section profile is facilitated.
