Description

HOLDING DEVICE FOR SECURING MOUNTING PARTS TO ROUND AND/OR MULTI-CORNERED PIPES AND CONVEYOR The invention relates to a holding device for securing mounting parts to round and/or multi-cornered pipes according to the preamble of claim 1, and to a conveyor according to the preamble of claim 12.

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

Very high labor costs are incurred in welding operations relative to the component. In addition, the components have to fit together as precisely as possible for the welding operation, since a further machining or correction step would only be possible with a great deal of effort.

Mounts manufactured with sheet bending structures are also very labor intensive. A blank must first be fabricated out a sheet based on the design drawing for the mount, to include the bending surfaces. This blank must then be bent exactly according to the construction specifications, so as to manufacture the provided mount. Most of the time, there is no variability here. Mounts fabricated in a sheet bending process require approx. 20% more material.

In addition, there is no easy way to fabricate special structures for mounts in a manufacturing process that involves welding and/or sheet bending operations.

Object The object of the invention is to provide a holding device that exhibits a distinctly improved functionality, simplified handling, a low material outlay, and an enhanced flexibility in use, and can further preferably be used in the food industry while satisfying the requirements placed on the latter.

Solution The object is achieved by a holding device according to claim 1 and a conveying system according to claim 12. Preferred embodiments and further developments are disclosed in the subclaims.

A holding device for securing mounting parts to round pipes and/or multi-cornered pipes, the holding device comprising a holder part made out of flat material and a holder counterpart, which can be detachably joined with the holder part and thereby form a passage opening for a pipe, wherein interior surface of the holder part comprises a cross section that 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, the flat material being a metal sheet comprising aluminium and/or iron.

By making the holder part out of a flat material, in form of a metal sheet comprising aluminum and/or iron, both the manufacturing effort and manufacturing costs for the holder part can be reduced. The holder part can be cut out of the flat material in a laser cutting process. The cut out holder part is not subjected to any further machining process in which it is bent. In addition, no further machining process that involves shaping through soldering takes place. It can only be provided that boreholes or elongated holes be worked into the holder part cut out of the flat material. It is also conceivable to introduce boreholes and/or oblong holes during the laser cutting process already.

Since an interior surface of the holder part comprises a cross section that 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 interior surface of the holder part is configured in such a way by comparison to the holder counterpart that the holder part can accommodate both round and multi-corner pipes. The term “interior surface” is used for the combination of all those surfaces with which a round or multi-cornered pipe can come into contact when accommodated by the holder part.

For example, the interior surface of the holder part comprises seven partial surfaces. In order to be suitable for accommodating a round pipe, three of the partial surfaces comprises a concave surface, the curvature of which corresponds to the radius R of a round pipe to be introduced, or to a round pipe to which the holding device is to be secured. Such a concave surface thus essentially corresponds to a segment of a lateral surface of a circular cylinder with radius R, or is shaped like such a segment. If a round pipe is placed in the holder part, three areas on the surface of the round pipe come into contact with the three partial surfaces of the holder part.

In order to additionally be suitable for accommodating a multi-cornered pipe, four of the partial surfaces of the interior surface of the holder part comprises flat surfaces. Viewed in cross section and extrapolated along a straight line, these flat surfaces exhibit an angular U-shape over one of the concave surfaces, in which a square pipe or multi-cornered pipe can be accommodated.

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

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

The holder part can comprise a recess.

A rotationally locked nut can be situated in the recess.

The holder counterpart can comprise a borehole situated in such a way that a screw can be inserted into the nut through the borehole in a holding position.

As a consequence, a fixed, but detachable connection can be ensured between the holder part and holder counterpart. The interaction between the holder counterpart and holder part can also yield a non-positive connection, specifically by inserting the projection of the holder into the recess opening of the holder counterpart, and inserting a screw into the borehole of the holder counterpart and into the rotationally locked nut of the holder part. The male thread of the screw and female thread of the nut are here each designed in such a way that a fixed, but detachable connection can be established between the two. When the nut is secured against rotation and loss in the recess of the holder part, only one tool is thus needed for the screw to loosen or tighten the screw, since the recess of the holder part replaces the fork wrench for holding the nut in place.

The holder part can comprise at least one liquid outlet. Condensed water and/or other liquids can be discharged via the liquid outlet, so that they do not accumulate in the holder part or between the holder part and a pipe located in the passage opening.

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

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

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

An interior surface of the holder counterpart can comprise a cross section that in one area is concavely bent in the shape of a circular arc. Given this shape for the holder counterpart, the counterpart provided is for round pipes. The interior surface of the holder counterpart can comprise a cross section resembling a circular arc, whose radius R essentially corresponds to the radius exhibited by a round pipe to be accommodated. The circular arc can exhibit a length that measures half the pipe circumference, or less or more than that. In this way, the holder counterpart partially envelops the round pipe. In a three dimensional view, the interior surface can thus exhibit a partial surface of a circular cylinder jacket with a radius R. The interior surface is regarded as the surface that comes into at least partial contact with the exterior surface of a round pipe.

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

In another embodiment, an interior surface of the holder counterpart can comprise a cross section that is straight in at least one area. Given this shape of the holder counterpart, the holder counterpart provided is for multicornered pipes. The interior surface of the holder counterpart can exhibit an angular progression in cross section, whose length essentially corresponds to the edge length of the square pipe to which the holding device can be secured. In this way, the holder counterpart partially envelops the square pipe. The interior surface can exhibit an angular U-shape in cross section, and an open box shape viewed three dimensionally. The interior surface is regarded as the surface that comes into at least partial contact with the exterior surface of a multi-cornered pipe.

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

A conveyor for conveying media, in particular liquid foods or precursors thereof, with at least one pipe comprises at least one holding device as mentioned above or further below.

The attached figures present exemplary aspects of the invention for better 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 of a 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 holding device 1 for securing mounting parts to round pipes. The holding device 1 comprises a holder part 2 and a holder counterpart 3, which are arranged in a so-called holding position on Fig. 1. The holder counterpart 3 is detachably 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 the holder counterpart 3, forming a passage opening 8 for a round pipe.

The term “passage opening” must here be understood to mean that a round pipe can be introduced into the passage opening 8 or a round pipe can be accommodated by the passage opening 8. The cross section of the passage opening 8 is here dimensioned or configured in such a way that the round pipe can be held in the passage opening 8 without an inadvertent relative 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 the holding 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 surface 9, the depicted holding device 1 is provided for round pipes, since the formed passage opening 8 essentially exhibits a circular cross section. The interior surface 9 is regarded as the surface that comes at least partially into contact with the exterior surface of a round pipe.

As evident from Fig. 5, the interior surface 9 of the holder counterpart 3 comprises a cross section resembling a circular arc, whose radius R essentially corresponds to the radius exhibited by a round pipe, to which the holding device 1 can be secured. The circular arc exhibits a length that measures somewhat less than half the pipe circumference. In this way, the holder counterpart 3 partially envelops the round pipe, so that the positive fit and non-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 3 interacts with the holder part 2 via the projection 11 of the holder part 2, which is 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 through a borehole 29 of the holder counterpart 3 (see Fig. 5) into a nut 6 situated in a recess 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 detachable connection can be established between the two. The nut 6 is arranged in the recess 7 of the holder part 2 secured against rotation and loss. In order to loosen or tighten the connecting device 4, one tool for the screw 5 is thus sufficient, since the recess 7 replaces the fork wrench for retaining the nut 6.

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

The holder part 2 comprises a liquid outlet 12, through which, for example, condensed water and/or other liquids can be discharged and do not accumulate in the holder part 2 or between the holder part 2 and a pipe located in the passage opening.

Fig. 1a shows how a round pipe 13 with a radius R is situated in the passage opening 8, which is formed by the holder part 2 and holder counterpart 3. The interior surface 9 of the holder counterpart 3 is partially in contact with the exterior surface of the round pipe 13. Viewed in cross section, the contact exists over a length measuring somewhat less than half the pipe circumference. Viewed three dimensionally, contact exists between the interior surface 9 of the holder counterpart 3 and the exterior surface of the round pipe 13 on a segment of the circular cylinder jacket.

Fig. 2 shows a second embodiment of a holding device 14 for securing mounting parts to square pipes. The holding device 14 comprises a holder part 2 corresponding to the one on Fig. 1, and a holder counterpart 15 located in a so-called holding position on Fig. 2. The holder counterpart 15 is detachably connected with the holder part 2 by a connecting device 4, 5, 6 and a projection 11 of the holder part 2, which engages into a recess of the holder counterpart 15, forming a passage opening 17 for a multi-cornered pipe.

The term “passage opening” must here be understood to mean that a multi-cornered pipe can be introduced into the passage opening 17 or a multicornered pipe can be accommodated by the passage opening 17. The cross section of the passage opening 17 is here dimensioned or configured in such a way that the multi-cornered pipe can be held in the passage opening 17 without an inadvertent relative movement taking place between the multicornered pipe and holding device 14. As a result, a multi-cornered pipe can be held in the holding position by means of the holding device 14, or the holding device 14 can be secured to a multi-cornered pipe.

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

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

The non-positive connection is produced as the holder counterpart 15 interacts with the holder part 2 via the projection 11 of the holder part 2, which is 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 through a borehole 33 of the holder counterpart 15 (see Fig. 6) into a nut 6 situated in a recess 7 of the holder part 2. As already mentioned, 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 detachable connection can be established between the two. The nut 6 is arranged in the recess 7 of the holder part 2 secured against rotation and loss. In order to loosen or tighten the connecting device 4, one tool for the screw 5 is thus sufficient, since the recess 7 replaces the fork wrench for retaining the nut 6.

Fig. 2a shows how a square pipe 18 is situated in the passage opening 17 formed by the holder part 2 and holder counterpart 15. The interior surface 16 of the holder counterpart 15 is partially in contact with the exterior surface of the square pipe 18.

Fig. 3 shows that a multi-cornered pipe 19 with a hexagonal cross section 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, 1 a, 2, 2a and 3. In 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 in the form of a metal sheet comprising aluminum and/or iron; the thickness is preferably selected in such a way as to ensure the stability of the holder part 2, and allow a recess 7 to be formed for accommodating the nut 6.

The interior surface 10 of the holder part 2 is composed of seven partial surfaces 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 “interior surface” is used for the combination of all surfaces with which a round or multi-cornered pipe can come into contact when accommodated by the holder part 2.

In order to be suitable for accommodating a round pipe 9, three of the partial surfaces 20, 21, 22 comprise a concave surface, whose curvature corresponds to the radius R of a round pipe to be introduced, or to a round pipe to which the holding device is to be secured. Such a concave surface thus essentially corresponds to a segment of a lateral surface of a circular cylinder with radius R. If a round pipe 9 is placed in the holder part 2, three areas on the surface of the round pipe 9 come into contact with the three partial surfaces 20, 21, 22.

In order to additionally be suitable for accommodating a multi-cornered pipe 18, 19, four of the partial surfaces 23, 24, 25 (the fourth partial surface is not visible on Fig. 4) of the interior surface 10 of the holder part 2 comprise flat surfaces. Viewed in cross section and extrapolated along a straight line, these flat 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 be accommodated.

Fig. 5 shows a holder counterpart 3 for round pipes 13. Given the shape of the holder counterpart 3, in particular of its interior surface 9, the holder counterpart 3 is provided for round pipes. The interior surface 9 comprises a cross section resembling a circular arc, whose radius R essentially corresponds to the radius exhibited by a round pipe, and viewed three dimensionally to a segment of a circular cylinder jacket. The interior surface 9 is regarded as the surface that comes at least partially into contact with the exterior surface of a round pipe 13. The circular arc exhibits a length that measures somewhat less than half the pipe circumference. In this way, the holder counterpart 3 can partially envelop a round pipe 13.

In a first area 28 of the holder counterpart 3, the already mentioned recess opening 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 the holder counterpart 3 is a borehole 29, into which a screw 5 of the connecting device 4 of the holding device 1 can be inserted. The designations “first” area and “second” area serve only to differentiate between the two areas, and otherwise 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 interior surface 16, the holding device 14 is provided for multi-cornered pipes 18, 19. The interior surface 16 comprises an angular U-shape in cross section, and an open box shape viewed three dimensionally. The interior surface 16 is regarded as the surface that comes into at least partial contact with the exterior 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 a multi-cornered pipe 18, 19. In this way, the holder counterpart 15 partially envelops the square pipe 18, 19. In a first area 32 of the holder counterpart 15, the already mentioned recess opening 31 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 34 of the holder counterpart 15 is a borehole 33, into which a screw 5 of the connecting device 4 of the holding device 14 can be inserted. The designations “first” area and “second” area serve only to differentiate between the two areas, and otherwise impose no further limitation on the two areas.

Fig. 7 shows a third embodiment of the holding device with a holder part 35 and a holder counterpart 3 for accommodating a round pipe 13, which are situated in the holding position on Fig. 7. In addition to the projection 36, the liquid outlet 38 and the recess 39 for the nut 6, the holder part 35 comprises six boreholes 40, 41, 42, 43, 44, 45 for fixing several components in place.

Fig. 8 shows a fourth embodiment of the holding device with a holder part 46 and a holder counterpart 3 for accommodating a round pipe 13, which are situated in the holding position on Fig. 8. In addition to the projection 57, the liquid outlet 49 and the recess 50 for the nut 6, the holder part 46 comprises two oblong holes 51, 52, which are provided for the variable fixation of components, for example of measuring sensors.

Fig. 9 shows a fifth embodiment of the holding device with a holder part 53 and a holder counterpart 3 for accommodating a round pipe 13, which are situated in the holding position on Fig. 9. In addition to the projection 54, the liquid outlet 56 and the recess 57 for the nut 6, the holder part 53 comprises two boreholes 57, 58, which can be used as a stable connecting variant. For example, U-shaped mounting brackets can be secured to exposed lines.
