Description

HOLDING DEVICE FOR SECURING MOUNTING PARTS TO ROUNDAND/OR MULTI-CORNERED PIPES AND CONVEYOR The invention relates to a holding device for securing mounting parts toround and/or multi-cornered pipes according to the preamble of claim 1, andto a conveyor according to the preamble of claim 13.

Prior Art Known in the art are various types of mounts, which can be joined witha pipe of varying cross section. ln general, these mounts are manufactured inwelding or sheet bending operations.

Very high labor costs are incurred in welding operations re|ative to thecomponent. ln addition, the components have to fit together as precisely aspossible for the welding operation, since a further machining or correctionstep would only be possible with a great deal of effort.

Mounts manufactured with sheet bending structures are also very laborintensive. A blank must first be fabricated out a sheet based on the designdrawing for the mount, to include the bending surfaces. This blank must thenbe bent exactly according to the construction specifications, so as tomanufacture the provided mount. Most of the time, there is no variability here.Mounts fabricated in a sheet bending process require approx. 20% morematerial. ln addition, there is no easy way to fabricate special structures formounts in a manufacturing process that involves welding and/or sheetbending operations.wii The object of the invention is to provide a holding device that exhibits adistinctly improved functionality, simplified handling, a low material outlay, andan enhanced flexibility in use, and can further preferably be used in the foodindustry while satisfying the requirements placed on the latter.

Solution 2 The object is achieved by a holding device according to claim 1 and aconveying system according to claim 13. Preferred embodiments and furtherdevelopments are disclosed in the subclaims.

A holding device for securing components to round pipes and/or multi-cornered pipes encompasses a holder part made out of flat material and aholder counterpart, which can be detachably joined with the holder part andthereby form a passage opening for a pipe.

By making the holder part out of a flat material, for example a metalsheet encompassing aluminum and/or iron, both the manufacturing effort andmanufacturing costs for the holder part can be reduced. The holder part canbe cut out of the flat material in a laser cutting process. The cut out holderpart is not subjected to any further machining process in which it is bent. lnaddition, no further machining process that involves shaping throughsoldering takes place. lt can only be provided that boreholes or elongatedholes be worked into the holder part cut out of the flat material. lt is alsoconceivable to introduce boreholes and/or oblong holes during the lasercutting process already.

The term “passage opening” must here be understood to mean that theround pipe or multi-cornered pipe can be introduced into the passage openingor a round pipe or multi-cornered pipe can be accommodated in the passageopening. The cross section of the passage opening is here dimensioned andconfigured in such a way that the round pipe or multi-cornered pipe can beheld in the passage opening without an inadvertent relative movement takingplace between the round pipe or multi-cornered pipe and holding device.

The holder part can exhibit a projection, and the holder counterpart canexhibit a recess opening, wherein the projection can be inserted into therecess opening of the holder counterpart.

The holder part can encompass a recess.

A rotationally locked nut can be situated in the recess.

The holder counterpart can encompass a borehole situated in such away that a screw can be inserted into the nut through the borehole in aholding position. 3 As a consequence, a fixed, but detachable connection can be ensuredbetween the holder part and holder counterpart. The interaction between theholder counterpart and holder part can also yield a non-positive connection,specifically by inserting the projection of the holder into the recess opening ofthe holder counterpart, and inserting a screw into the borehole of the holdercounterpart and into the rotationally locked nut of the holder part. The malethread of the screw and female thread of the nut are here each designed insuch a way that a fixed, but detachable connection can be establishedbetween the two. When the nut is secured against rotation and loss in therecess of the holder part, only one tool is thus needed for the screw to loosenor tighten the screw, since the recess of the holder part replaces the forkwrench for holding the nut in place.

The holder part can encompass at least one liquid outlet. Condensedwater and/or other liquids can be discharged via the liquid outlet, so that theydo not accumulate in the holder part or between the holder part and a pipelocated in the passage opening.

The holder part can encompass at least one thermal expansion joint.This makes it possible to avoid stress in the holder part, for example whiletransporting hot liquid through a pipe situated in the passage opening.

The holder part can encompass one or more boreholes. The one ormore boreholes can be used for a stable connection variant. For example, U-shaped mounting brackets can be secured to exposed lines. Given a largernumber of boreholes, for example more than five boreholes, the latter can beused to fix several components in place.

The holder part can encompass one or more oblong holes. The one ormore oblong holes can be provided for the variable fixation of components,for example of measuring sensors.

An interior surface of the holder part can encompass a cross sectionthat is concavely bent in the shape of a circular arc in at least one first area,and is straight in at least one second area. As a consequence, the interiorsurface of the holder part is configured in such a way by comparison to theholder counterpart that the holder part can accommodate both round and 4 multi-corner pipes. The term “interior surface” is used for the combination ofall those surfaces with which a round or multi-cornered pipe can come intocontact when accommodated by the holder part.

For example, the interior surface of the holder part encompassesseven partial surfaces. ln order to be suitable for accommodating a roundpipe, three of the partial surfaces exhibit a concave surface, the curvature ofwhich corresponds to the radius R of a round pipe to be introduced, or to around pipe to which the holding device is to be secured. Such a concavesurface thus essentially corresponds to a segment of a lateral surface of acircular cylinder with radius R, or is shaped like such a segment. lf a roundpipe is placed in the holder part, three areas on the surface of the round pipecome into contact with the three partial surfaces of the holder part. ln order to additionally be suitable for accommodating a multi-corneredpipe, four of the partial surfaces of the interior surface of the holder partexhibit flat surfaces. Viewed in cross section and extrapolated along a straightline, these flat surfaces exhibit an angular U-shape over one of the concavesurfaces, in which a square pipe or multi-cornered pipe can beaccommodated.

An interior surface of the holder counterpart can encompass a crosssection that in one area is concavely bent in the shape of a circular arc. Giventhis shape for the holder counterpart, the counterpart provided is for roundpipes. The interior surface of the holder counterpart can exhibit a crosssection resembling a circular arc, whose radius R essentially corresponds tothe radius exhibited by a round pipe to be accommodated. The circular arccan exhibit a length that measures half the pipe circumference, or less ormore than that. ln this way, the holder counterpart partially envelops theround pipe. ln a three dimensional view, the interior surface can thus exhibit apartial surface of a circular cylinderjacket with a radius R. The interior surfaceis regarded as the surface that comes into at least partial contact with theexterior surface of a round pipe.

A passage opening formed by such a holder counterpart and holderpart exhibits an essentially circular cross section. 5 ln another embodiment, an interior surface of the holder counterpartcan encompass a cross section that is straight in at least one area. Given thisshape of the holder counterpart, the holder counterpart provided is for multi-cornered pipes. The interior surface of the holder counterpart can exhibit anangular progression in cross section, whose length essentially corresponds tothe edge length of the square pipe to which the holding device can besecured. ln this way, the holder counterpart partially envelops the squarepipe. The interior surface can exhibit an angular U-shape in cross section,and an open box shape viewed three dimensionally. The interior surface isregarded as the surface that comes into at least partial contact with theexterior surface of a multi-cornered pipe.

A passage opening formed by such a holder counterpart and holderpart exhibits an essentially angular cross section.

A conveyor for conveying media, in particular liquid foods or precursorsthereof, with at least one pipe encompasses at least one holding device asmentioned above or further below.

The attached figures present exemplary aspects of the invention forbetter understanding and illustrative purposes. Shown on: Fig. 1 is a first embodiment of a holding device, Fig. 1a is the holding device from Fig. 1 with a round pipe, Fig. 2 is a second embodiment of a holding device, Fig. 2a is the holding device from Fig. 2 with a square pipe, Fig. 3 is the holding device from Fig. 2 with a hexagonal pipe, Fig. 4 is a holder part, Fig. 5 is a holder counterpart for round pipes, Fig. 6 is a holder counterpart for multi-cornered pipes, Fig. 7 is a third embodiment ofa holding device, Fig. 8 is a fourth embodiment of a holding device, and Fig. 9 is a fifth embodiment of a holding device, Fig. 1 presents a schematic view of a first embodiment of a holdingdevice 1 for securing mounting parts to round pipes. The holding device 1encompasses a holder part 2 and a holder counterpart 3, which are arranged 6 in a so-called holding position on Fig. 1. The holder counterpart 3 isdetachably joined with the holder part 2 by means of a connecting device 4, 5,6 and a projection 11 of the holder part 2, which engages into a recess of theholder counterpart 3, forming a passage opening 8 for a round pipe.

The term “passage opening” must here be understood to mean that around pipe can be introduced into the passage opening 8 or a round pipe canbe accommodated by the passage opening 8. The cross section of thepassage opening 8 is here dimensioned or configured in such a way that theround pipe can be held in the passage opening 8 without an inadvertentrelative movement taking place between the round pipe and holding device 1.As a result, a round pipe can be held in the holding position by means of theholding device 1, or the holding device 1 can be secured to a round pipe.Given the shape of the holder counterpart 3, in particular of its interior surface9, the depicted holding device 1 is provided for round pipes, since the formedpassage opening 8 essentially exhibits a circular cross section. The interiorsurface 9 is regarded as the surface that comes at least partially into contactwith the exterior surface of a round pipe.

As evident from Fig. 5, the interior surface 9 of the holder counterpart 3exhibits a cross section resembling a circular arc, whose radius R essentiallycorresponds to the radius exhibited by a round pipe, to which the holdingdevice 1 can be secured. The circular arc exhibits a length that measuressomewhat less than halfthe pipe circumference. ln this way, the holdercounterpart 3 partially envelops the round pipe, so that the positive fit andnon-positive fit in conjunction with the holder part 2 can hold the round pipe,so that the holding device 1 can be secured thereto.

The non-positive connection is produced as the holder counterpart 3interacts with the holder part 2 via the projection 11 of the holder part 2, whichis inserted into a recess opening 27 of the holder counterpart 3 (see Fig. 5),and the connecting device 4 comprising a screw 5, which is inserted througha borehole 29 of the holder counterpart 3 (see Fig. 5) into a nut 6 situated in arecess 7 of the holder part 2. The male thread of the screw 5 and the female thread of the nut 6 are here each designed in such a way that a fixed, but 7 detachable connection can be established between the two. The nut 6 isarranged in the recess 7 of the holder part 2 secured against rotation andloss. ln order to loosen or tighten the connecting device 4, one tool for thescrew 5 is thus sufficient, since the recess 7 replaces the fork wrench forretaining the nut 6.

By contrast, the interior surface 10 of the holder part 2 is designed insuch a way in comparison to the depicted holder counterpart 3 that the holderpart 2 can accommodate both round and multi-cornered pipes; this is alsoevident from the illustrations on Fig. 1a, 2a and 3, which show one, i.e., asingle, embodiment of the holding device 1 with various holder counterparts3. The interior surface 10 of the holder part 2 will be discussed in more detailin the description to Fig. 4.

The holder part 2 exhibits a liquid outlet 12, through which, forexample, condensed water and/or other liquids can be discharged and do notaccumulate in the holder part 2 or between the holder part 2 and a pipelocated in the passage opening.

Fig. 1a shows how a round pipe 13 with a radius R is situated in thepassage opening 8, which is formed by the holder part 2 and holdercounterpart 3. The interior surface 9 of the holder counterpart 3 is partially incontact with the exterior surface of the round pipe 13. Viewed in crosssection, the contact exists over a length measuring somewhat less than halfthe pipe circumference. Viewed three dimensionally, contact exists betweenthe interior surface 9 of the holder counterpart 3 and the exterior surface ofthe round pipe 13 on a segment of the circular cylinderjacket.

Fig. 2 shows a second embodiment of a holding device 14 for securingmounting parts to square pipes. The holding device 14 encompasses a holderpart 2 corresponding to the one on Fig. 1, and a holder counterpart 15 locatedin a so-called holding position on Fig. 2. The holder counterpart 15 isdetachably connected with the holder part 2 by a connecting device 4, 5, 6and a projection 11 of the holder part 2, which engages into a recess of theholder counterpart 15, forming a passage opening 17 for a multi-cornered pipe. 8 The term “passage opening” must here be understood to mean that amulti-cornered pipe can be introduced into the passage opening 17 or a multi-cornered pipe can be accommodated by the passage opening 17. The crosssection of the passage opening 17 is here dimensioned or configured in sucha way that the multi-cornered pipe can be held in the passage opening 17without an inadvertent relative movement taking place between the multi-cornered pipe and holding device 14. As a result, a multi-cornered pipe canbe held in the holding position by means of the holding device 14, or theholding device 14 can be secured to a multi-cornered pipe.

Given the shape of the holder counterpart 15, in particular of its interiorsurface 16, the depicted holding device 14 is provided for multi-corneredpipes, since the formed passage opening 17 exhibits an angular cross sectionin the lower and upper area. The interior surface 16 is regarded as thesurface that comes at least partially into contact with the exterior surface of amulti-cornered pipe.

As evident from Fig. 6, the interior surface 16 of the holder counterpart15 exhibits a cross section with an angular progression, whose lengthessentially corresponds to the edge length of the square pipe, to which theholding device 14 can be secured. ln this way, the holder counterpart 15partially envelops the square pipe, so that the positive fit and non-positive fitin conjunction with the holder part 2 can hold the multi-cornered pipe, so thatthe holding device 14 can be secured thereto.

The non-positive connection is produced as the holder counterpart 15interacts with the holder part 2 via the projection 11 of the holder part 2, whichis inserted into a recess opening 31 of the holder counterpart 15 (see Fig. 6),and the connecting device 4 comprising a screw 5, which is inserted througha borehole 33 of the holder counterpart 15 (see Fig. 6) into a nut 6 situated ina recess 7 of the holder part 2. As already mentioned, the male thread of thescrew 5 and the female thread of the nut 6 are here each designed in such away that a fixed, but detachable connection can be established between thetwo. The nut 6 is arranged in the recess 7 of the holder part 2 secured againstrotation and loss. ln order to loosen or tighten the connecting device 4, one 9 tool for the screw 5 is thus sufficient, since the recess 7 replaces the forkwrench for retaining the nut 6.

Fig. 2a shows how a square pipe 18 is situated in the passage opening17 formed by the holder part 2 and holder counterpart 15. The interior surface16 of the holder counterpart 15 is partially in contact with the exterior surfaceof the square pipe 18.

Fig. 3 shows that a multi-cornered pipe 19 with a hexagonal crosssection can also be accommodated and held in the arrangement from Fig. 2.

Fig. 4 shows an inclined view of the holder part 2 from Fig. 1, 1a, 2, 2aand 3. ln particular the width of the holder part 2 is not shown to scale on Fig.4. The holder part 2 is made out of a flat material; the thickness is preferablyselected in such a way as to ensure the stability of the holder part 2, andallow a recess 7 to be formed for accommodating the nut 6.The interior surface 10 of the holder part 2 is composed of seven partialsurfaces 20, 21, 22, 23, 24, 25, wherein six of these partial surfaces 20, 21,22, 23, 24, 25 are at least partially visible on the figure. The term “interiorsurface” is used for the combination of all surfaces with which a round ormulti-cornered pipe can come into contact when accommodated by the holderpart 2. ln order to be suitable for accommodating a round pipe 9, three of thepartial surfaces 20, 21, 22 exhibit a concave surface, whose curvaturecorresponds to the radius R of a round pipe to be introduced, or to a roundpipe to which the holding device is to be secured. Such a concave surfacethus essentially corresponds to a segment of a lateral surface of a circularcylinder with radius R. lf a round pipe 9 is placed in the holder part 2, threeareas on the surface of the round pipe 9 come into contact with the threepartial surfaces 20, 21, 22. ln order to additionally be suitable for accommodating a multi-corneredpipe 18, 19, four of the partial surfaces 23, 24, 25 (the fourth partial surface isnot visible on Fig. 4) of the interior surface 10 of the holder part 2 exhibit flatsurfaces. Viewed in cross section and extrapolated along a straight line, theseflat surfaces 23, 24, 25 form an angular U-shape over one of the concave surfaces 21, in which a square pipe 18 or multi-cornered pipe 19 can beaccommodated.

The interior surface 9exhibits a cross section resembling a circular arc, whose radius R essentiallycorresponds to the radius exhibited by a round pipe, and viewed threedimensionally to a segment of a circular cylinderjacket. The interior surface 9is regarded as the surface that comes at least partially into contact with theexterior surface of a round pipe 13. The circular arc exhibits a length thatmeasures somewhat less than half the pipe circumference. ln this way, theholder counterpart 3 can partially envelop a round pipe 13.ln a first area 28 of the holder counterpart 3, the already mentioned recessopening 27 is provided, which is designed to accommodate the projection 11,36, 47, 54 of the holder part 2, 35, 46, 53. Provided in a second area 30 of theholder counterpart 3 is a borehole 29, into which a screw 5 of the connectingdevice 4 of the holding device 1 can be inserted. The designations “first” areaand “second” area serve only to differentiate between the two areas, andotherwise impose no further limitation on the two areas.

Fig. 6 shows a holder counterpart 15 for multi-cornered pipes 18, 19.Given the shape of the holder counterpart 15, in particular of its interiorsurface 16, the holding device 14 is provided for multi-cornered pipes 18, 19.The interior surface 16 exhibits an angular U-shape in cross section, and anopen box shape viewed three dimensionally. The interior surface 16 isregarded as the surface that comes into at least partial contact with theexterior surface of a multi-cornered pipe 18, 19. One side of the angular U-shape exhibits a length that essentially corresponds to the edge length of amulti-cornered pipe 18, 19. ln this way, the holder counterpart 15 partiallyenvelops the square pipe 18, 19. ln a first area 32 of the holder counterpart15, the already mentioned recess opening 31 is provided, which is designedto accommodate the projection 11, 36, 47, 54 of the holder part 2, 35, 46, 53.Provided in a second area 34 of the holder counterpart 15 is a borehole 33, 11 into which a screw 5 of the connecting device 4 of the holding device 14 canbe inserted. The designations “first” area and “second” area serve only todifferentiate between the two areas, and otherwise impose no furtherIimitation on the two areas.
