Description

TECHNICAL FIELD

[0001] The invention relates to a conveying device comprising a conveying arrangement for transporting goods along a transport direction and at least one guide body having a bottom face and a first side face which is in particular flat.

[0002] The invention also relates to the use of a guide body in a conveying arrangement for displacing goods towards the center of a conveying surface, wherein the goods are transported along a transport direction on the conveying surface by the conveying arrangement. BACKGROUND

[0003] Conveying arrangements for transporting goods along a transport direction are known from the prior art, for example belt conveyors. The problem with these conveying arrangements is that the goods transported with the conveying arrangement can fall off the conveying arrangement. This problem is usually solved with lateral guides which are intended to prevent the goods from falling off. However, lateral guides have the disadvantage that the goods transported with the conveying arrangement are difficult to access. Furthermore, lateral guides are expensive and also require structural space.

[0004] Furthermore, especially in conveying arrangements which have a conveying surface for the goods and which have lateral edge regions arranged at the side of the conveying surface in the transport direction, it can occur that the goods fall off the conveying arrangement, despite the presence of lateral guides. For example, in some belt conveyors, the conveying surface designed as a belt is narrower than the frame, so that lateral edge regions remain uncovered by the belt at the side of the belt. It can occur when transporting the goods with the conveying arrangement that the goods come to rest completely or partially in the lateral edge regions and more easily cause a jam of the goods on the conveying arrangement. Due to the continuously running belt and / or subsequent goods, the goods can be displaced and / or stacked and thus fall off the conveying arrangement. SUMMARY

[0005] Against this background, it is an object of the present invention to provide means for reducing the risk of goods falling off the conveying arrangement. Furthermore, it is an object of the present invention to provide means for reducing the risk of a jam of the goods on the conveying arrangement. It is in particular an object of the present invention to provide means for reducing the risk of goods falling off the conveying arrangement and the risk of a jam of the goods and at the same time enabling access to the goods on the conveying arrangement.

[0006] The objects of the invention are achieved by the features of the conveying device. Advantageous design proposals are given in the detailed description.

[0007] The object is therefore achieved by a conveying device comprising a conveying arrangement for transporting goods along a transport direction and at least one guide body having a base surface and a first side surface, wherein the conveying arrangement has a conveying surface for the goods and a lateral edge region arranged at a side of the conveying surface in the transport direction, wherein the first side surface forms an internal angle of less than 90 degrees with the base surface, wherein the guide body is arranged and / or designed in such a way that at least a portion of the base surface of the guide body lies on the lateral edge region and in such a way that a normal vector of the first side surface points obliquely against the transport direction to the center of the conveying surface.

[0008] The object is furthermore achieved by the use of a guide body in a conveying arrangement for displacing goods towards the center of a conveying surface, wherein the goods are transported by the conveying arrangement on the conveying surface along a transport direction, wherein the conveying arrangement has a lateral edge region arranged at a side of the conveying surface, wherein the guide body has a base surface and a first side surface, wherein the first side surface forms an internal angle of less than 90 degrees with the base surface, and wherein the guide body is designed in such a way that, in the case that at least a portion of the base surface of the guide body lies on the lateral edge region, a normal vector of the first side surface of the guide body points obliquely against the transport direction to the center of the conveying surface.

[0009] The core idea of the present application is therefore a conveying device comprising a conveying arrangement and a guide body of a specific design as well as the use of the guide body in the conveying arrangement. The guide body has a base surface and a preferably flat first side surface and can cause the goods transported with the conveying arrangement to be moved towards the center of the conveying surface by interaction with the guide body. In this way, the risk of the goods falling off the conveying arrangement is reduced in a simple manner. The guide body also reduces the risk of the goods remaining on the lateral edge region of the conveying arrangement and the risk of a jam being caused thereby, in that the goods are moved towards the center of the conveying surface by interaction with the guide body. The goods can therefore be continued to be transported over the conveying surface, so that the risk of a jam being caused is greatly reduced. The goods transported with the conveying arrangement can also be easily reached. The guide body has the particular advantage that it can also be cost-effectively installed in already existing conveying arrangements.

[0010] The first side preferably adjoins the bottom of the guide body. Since the first side of the guide body has an internal angle of less than 90 degrees with the bottom and the guide body is arranged and / or designed such that at least a portion of the bottom of the guide body lies on the lateral edge region, an angle of more than 90 degrees is preferably produced between the first side of the guide body and the conveying surface on which the goods item can be transported. This internal angle refers to the angle of the preferably planar first side with the plane of the bottom inside the guide body, or, in the case where the first side and the bottom do not directly adjoin one another, to the angle of the plane of the preferably planar first side with the plane of the bottom, measured on the side of the guide body. In other words, the guide body is designed in such a way that, in the case where at least a portion of the bottom of the guide body is arranged on the lateral edge region, the first side does not stand perpendicularly on the conveying surface, but is inclined thereto. Furthermore, it is proposed that the guide body is arranged and / or designed in such a way that the normal vector of the preferably planar first side points obliquely against the transport direction to the center of the conveying surface. The center of the conveying surface preferably refers to the center line of the conveying surface, which extends in the transport direction and has the same distance from both edges of the conveying surface. In other words, the first side of the guide body preferably inclines obliquely away from this center in the transport direction. This causes a goods item which is transported on the conveying surface in the transport direction and which is located near the lateral edge region to be pushed by the conveying surface in the case of interaction with the guide body and in particular in the case of interaction with the first side of the guide body, to move towards the center of the conveying surface.

[0011] Preferably, the conveying device is designed in such a way that the lateral edge region is embodied flat and at the same height as the conveying surface. Further preferably, the lateral edge region is preferably a region of the conveying device which is not covered by the conveying surface, particularly preferably a base of the conveying device which is not covered by the conveying surface. The conveying device can have a lateral edge region on both sides (with respect to the center of the conveying surface) or only on one side of the conveying surface.

[0012] In other words and with reference to an orthogonal coordinate system (whose x-axis is given by the transport direction, whose z-axis is given by the surface normal of the conveying surface and whose y-axis is perpendicular to both of the above-mentioned axes, thereby resulting in a right-handed orthogonal coordinate system), the normal vector of the first side preferably has a first vector component in the negative x-direction (i.e. opposite to the transport direction) which is greater than zero, a second vector component in the positive or negative y-direction which is greater than zero and a third vector component in the z-direction which is greater than zero. Depending on whether the guide body is arranged on the lateral edge region to the left or to the right of the center of the conveying surface, the vector component of the normal vector lies in the positive or negative y-direction, whereby the normal vector points obliquely to the center of the conveying surface. In other words, the normal vector of the first side is preferably not parallel to the transport direction and also not perpendicular to the transport direction.

[0013] According to a preferred refinement of the application, the guide body is designed in such a way that the goods items transported by the conveying device can slide upwards on the first side of the guide body. This upward sliding preferably in particular means a movement of the center of gravity of the goods item having a component parallel to the surface normal of the conveying plane, i.e. parallel to the z-axis of the above-defined right-handed orthogonal coordinate system. For example, the goods item can stand on the first side as a result of the pushing by the conveying plane and due to the friction with the first side of the guide body. The center of gravity of the goods item is thereby moved with a component parallel to the surface normal of the conveying plane. In order to further simplify the upward sliding of the goods item on the first side, it is further preferred that the internal angle between the bottom surface and the first side of the guide body is preferably between 30 and 85 degrees, particularly preferably between 50 and 80 degrees, very particularly preferably between 60 and 80 degrees. It is further preferred that this internal angle is coordinated with the transport speed and / or the weight of the goods items transported with the conveying device.

[0014] It is further preferred in this regard that the normal vector of the first side lies in a reference plane perpendicular to the conveying plane and which encloses an angle of 15 to 80 degrees, preferably 20 to 70 degrees, particularly preferably 25 to 60 degrees, with the transport direction. This further simplifies the movement of the goods item by interaction with the guide body and in particular by upward sliding on the first side towards the center of the conveying plane.

[0015] According to a further preferred refinement of the application, it is provided that the guide body has a preferably flat second side and is designed in such a way that the normal vector of the second side lies in a reference plane perpendicular to the conveying plane and perpendicular to the transport direction. The reference plane of the normal vector of the second side is thus preferably parallel to the yz-plane of the above-described right-handed orthogonal coordinate system. The second side preferably adjoins the first side of the guide body and further preferably adjoins the bottom surface and the first side. It is further preferred that the guide body is designed in such a way that, in the case that at least a portion of the bottom surface of the guide body is arranged on the lateral edge region, the second side is located next to the first side in the transport direction. The described design of the second side further improves the functionality of the guide body in such a way that a goods item that slides upwards on the first side of the guide body can slide downwards along the second side of the guide body and thereby be displaced in the direction of the center of the conveying plane.

[0016] It is further preferred that the guide body has a third side, which is preferably flat, and is designed such that the internal angle between the third side and the bottom side is less than or equal to 90 degrees. The internal angle between the third side and the bottom side is preferably equal to 90 degrees. The third side is preferably adjacent to the first side of the guide body and further preferably adjacent to the bottom side and the first side. It is furthermore preferred that the guide body is designed in such a way that, in the case that at least a portion of the bottom side of the guide body is arranged on the lateral edge region, the third side is further away from the center of the conveying surface than the second side. The third side is preferably parallel to the transport direction. This has the advantage that the guide body does not protrude laterally beyond the edge of the conveying device and thus does not pose a risk of injury to personnel working at the conveying device.

[0017] In terms of the design of the bottom side, a further preferred development according to the application proposes that the ratio of the longest line segment connecting two points of the boundary line of the bottom side to the shortest line segment connecting two points of the boundary line is less than or equal to 5. In other words, the guide body preferably does not have the shape of a lateral guide that extends a long distance along the conveying surface and is very long and narrow. Instead, the bottom side of the guide body has a shape whose length-to-width ratio, i.e. the ratio of the longest line segment connecting two points of the boundary line to the shortest line segment connecting two points on the boundary line, is less than or equal to 5, preferably less than or equal to 4, particularly preferably less than or equal to 3. Correspondingly, the guide body also does not extend a long distance along the conveying surface. Thereby it is ensured that the guide body does not obstruct access to the conveying surface and thereby also to the items of cargo transported with the conveying surface. Furthermore, the guide body has very good stability based on this ratio.

[0018] Furthermore, it is preferred in this regard that the length of the longest line segment connecting two points of the boundary line is between 10 cm and 70 cm, preferably between 15 cm and 60 cm, particularly preferably between 20 cm and 55 cm. And / or the length of the shortest line segment connecting two points of the boundary line is between 15 cm and 45 cm, preferably between 20 cm and 40 cm, particularly preferably between 25 cm and 35 cm.

[0019] Furthermore in terms of the bottom side, a preferred development according to the application proposes that the bottom side of the guide body is polygonal, preferably quadrangular. This has proven to be particularly suitable for the function of the guide body.

[0020] A further preferred development according to the application in this regard proposes that the bottom side of the guide body is trapezoidal, that the two base sides of the trapezoid that are parallel to each other are parallel to the transport direction of the conveying device, and that the shorter base side of the trapezoid is closer to the center of the conveying surface than the longer base side of the trapezoid. This can be implemented in a simple manner to arrange the guide body with at least a portion of its bottom side on the lateral edge region.

[0021] It is further preferred to propose that the base surface of the guide body is a right-angled trapezoid. A right-angled trapezoid has exactly two right-angled inner angles in addition to two edges which are parallel to each other and furthermore has two further inner angles which each have a value different from 90 degrees. It is further preferred in this regard to propose that the guide body and the base surface of its right-angled trapezoidal shape are oriented in such a way that the two right-angled inner angles are located behind the two further inner angles of the trapezoid in the transport direction of the conveying device. In other words, according to the preferred development of the application, it is proposed that the base surface of the guide body is a right-angled trapezoid with exactly two right-angled inner angles and that these two right-angled inner angles are located behind the two further inner angles of the trapezoid in the transport direction. This ensures that the normal vector of the first side surface of the guide body can be tilted in particular simply to point against the transport direction to the center of the conveying surface.

[0022] In terms of the design of the guide body, a further preferred development according to the application proposes that the guide body is a polyhedron, in particular a convex polyhedron. A polyhedron is a three-dimensional body completely defined by planes. A polyhedron is convex when all points of the connecting line segment between two points of the geometric body are also part of the geometric body. In other words, it is preferably proposed that the guide body has no recesses or depressions. A guide body designed as a polyhedron and in particular as a convex polyhedron is particularly easy to manufacture.

[0023] A further preferred development according to the application proposes that the guide body is designed as a pyramid or truncated pyramid. A truncated pyramid with a trapezoidal base surface is particularly preferred. This shape has proven particularly suitable for achieving the object that the first side surface can have an inner intersection angle with the base surface of less than 90 degrees and that the normal vector of the first side surface can be tilted against the transport direction to the center of the conveying surface in the case that the guide body is arranged with at least a portion of its base surface on the lateral edge region.

[0024] Furthermore, it is proposed in this regard that the tip of the pyramid or the virtual tip of the truncated pyramid is located above the base surface of the guide body. This enhances the stability of the guide body, which is advantageous in particular for heavier items.

[0025] In terms of the height of the guide body, it is further preferred to propose that the height of the guide body, measured in the manner of a surface normal parallel to the base surface, is between 5 cm and 50 cm, preferably between 10 cm and 40 cm, particularly preferably between 15 cm and 30 cm. This height range has proven particularly advantageous for preventing items from falling.

[0026] As already mentioned, the guide body is arranged and / or designed in such a way that at least a portion of the bottom surface of the guide body lies on the lateral edge region. In this regard it is proposed according to a preferred refinement that the guide body is designed and / or arranged in such a way that the entire bottom surface lies on the lateral edge region. In this alternative, therefore, the bottom surface of the guide body is arranged completely in the lateral edge region of the conveying device. This makes the installation of the guide body easy.

[0027] Instead of this, it is proposed according to a further preferred refinement of the application in this regard that the guide body is designed and / or arranged in such a way that a further portion of the bottom surface of the guide body lies above the conveying surface and in such a way that the further portion of the bottom surface is spaced apart from the conveying surface, is designed frictionless with respect to the conveying surface and / or the friction with respect to the conveying surface does not affect the conveying function of the conveying device. In other words, a portion of the bottom surface can lie on the lateral edge region and a further portion of the bottom surface can lie above the conveying surface. This is advantageous, in particular, for very narrow lateral edge regions. It is further proposed according to this alternative that the portion of the bottom surface which lies above the conveying surface has a slight friction with respect to the conveying surface or preferably no friction at all, so that the conveying function is not affected. This can be achieved, for example, by a suitable material selection and / or by spacing the further portion of the bottom surface from the conveying surface, for example by a slight offset in the bottom surface of the guide body.

[0028] In terms of the design of the conveying device, it is proposed according to a preferred refinement that the conveying device is a belt conveyor and preferably a telescopic belt conveyor. In a belt conveyor, also referred to as a conveyor belt or belt machine, the conveying surface is composed of a belt and / or a band. A telescopic belt conveyor also has the advantage that the conveying length can be adjusted steplessly.

[0029] As already mentioned, the conveying device comprises at least one guide body. It can be proposed in this regard, preferably, that the conveying device comprises a plurality of guide bodies. It is further proposed, preferably, that all guide bodies are designed in such a way that the first side surface of all guide bodies has an internal angle of less than 90 degrees with the respective bottom surface, and all guide bodies are arranged and / or designed in such a way that at least a portion of the respective bottom surface of these guide bodies lies on the lateral edge region and in such a way that the normal vector of the first side surface of all guide bodies is inclinedly directed against the center of the conveying surface in the transport direction.

[0030] In this regard, a preferred refinement according to the application further proposes that the conveying device comprises a plurality of guide bodies, wherein the guide bodies are arranged on both sides of the center of the conveying surface in such a way that no guide body is arranged opposite each guide body, on the other side of the center, in a direction perpendicular to the transport direction. In other words, two guide bodies are not arranged simultaneously on the right and left side of the center of the conveying surface at the same position with reference to the transport direction. Thereby, a narrow region is avoided when transporting the goods.

[0031] According to a further preferred refinement, in the case of a plurality of guide bodies, it is proposed that the guide bodies are arranged uniformly, offset from one another, on both sides of the center of the conveying surface. It is thereby preferably proposed that the spacing between two guide bodies on one side of the center is correspondingly the same for all guide bodies on this side, and further preferably also the same as the spacing between two guide bodies, successive to one another, on the other side of the center. For example, the guide bodies are arranged at a spacing of 0.3 m, 0.5 m, 0.7 m, 1 m or 1.2 m along the conveying surface. Furthermore, the guide bodies on one side of the center are preferably arranged relative to the guide bodies on the other side of the center such that the spacing of a guide body on one side is the same as the spacing of two guide bodies, adjacent to one another, on the other side.

[0038] The described embodiments are merely examples, which can be modified and / or supplemented in various ways within the scope of the application. Each feature described in relation to an embodiment can be used independently of other features or in combination with other features in any other embodiment. Each feature described in relation to an embodiment of a certain category can also be applied in a corresponding manner in an embodiment of another category.

[0039] Figure 1 A schematic view of a guide body 10 according to an embodiment of the application is shown from various perspectives. The guide body 10 has a truncated pyramid shape in the present embodiment, wherein the base surface 12 of the guide body 10 is trapezoidal, which can be seen particularly well in Figure 1 a). Furthermore, the guide body 10 has a first side surface 14 which is flat here, wherein the first side surface 14 has an internal angle 16 of less than 90 degrees, here 65 degrees, with the base surface 12, which can be seen best in the perspective of Figure 1 c).

[0040] The trapezoidal base surface 12 has two right-angled internal angles 18. Furthermore, the base surface 12 of the guide body 10 is dimensioned such that the ratio of the longest line segment 22 connecting two points of the boundary line 20 of the base surface 12 to the shortest line segment 24 connecting two points of the boundary line 20 is less than or equal to 5. As can be seen best in Figure 1 b), the ratio of the longest line segment 22 to the shortest line segment 24 is approximately 2 here. Furthermore, the longest line segment 22 is 59 cm long here and the shortest line segment 24 is 31 cm long here.

[0041] The guide body 10 also has a second side surface 26 and a third side surface 28, which will be explained below. Furthermore, the guide body designed as a truncated pyramid is formed such that a virtual tip 30 of the truncated pyramid is located above the base surface 12. In the present embodiment, the height 32 of the guide body is 23 cm.

[0042] Figure 2 Two schematic views of a conveying device 34 comprising a conveying means 36 and a guide body 10 according to two further embodiments of the application are shown. The conveying means 36 is designed as a belt conveyor 36 in the two embodiments shown. The conveying means 36 thus has a conveying surface 38 designed as a belt, on which conveying surface 38 goods items (not shown) can be transported in a transport direction 40. The conveying means 36 has lateral edge regions 42 at the sides of the conveying surface 38. The lateral edge regions 42 are not covered by the conveying surface 38. The lateral edge regions 42 are flat and designed to be at the same height as the conveying surface 38.

[0043] In the embodiment of the conveying device 34 shown in Figure 2 a), the guide body 10 is arranged such that a portion of the base surface 12 of the guide body lies on the lateral edge region 42 and a further portion of the base surface 12 of the guide body lies above the conveying surface 38. In the embodiment of the conveying device 34 shown in Figure 2 b), the guide body 10 is arranged such that the entire base surface 12 of the guide body 10 lies on the lateral edge region 42.

[0044] Furthermore in Figure 2 , in particular Figure 2It can be seen in the embodiment of a) that the guiding body 10 is designed and / or arranged in such a way that the normal vector 44 of the first side 14 is inclined against the transport direction 40 and points to the center 46 of the conveying surface 38. In Figure 2 In order to better illustrate the effect in a), the projection 48 of the normal vector 44 on the conveying surface 38 is also shown, in order to make the inclination of the normal vector 44 against the transport direction 40 and in the direction of the center 46 more apparent. It can also be seen that the guiding body 10 is designed in such a way that the normal vector 50 of the second side 26 lies in a reference plane 52 which is perpendicular to the conveying surface 38 and perpendicular to the transport direction 40.

[0045] The guiding body 10 is therefore designed in such a way that the goods item transported by the conveying device 36 can slide upwards on the first side 14 of the guiding body 10 and be displaced by interaction with the guiding body 10 in the direction of the center 46 of the conveying surface 38.

[0046] Figure 3 Two schematic views of different perspectives of a conveying installation 34 according to a further embodiment of the application are shown. In this embodiment, the conveying installation 34 has a conveying device 36 for transporting goods items in the transport direction 40 and a plurality, here four, guiding bodies 10. It can be seen very well in the perspective of a) (showing the conveying installation 34 from above), in particular, that the two parallel base sides 54a, 54b of the base face 12 of the guiding body 10, which is designed as a trapezium, are parallel to the transport direction 40 of the conveying device 36. Furthermore, the shorter base side 54a is closer to the center 46 of the conveying surface 38 than the longer base side 54b. It can also be seen very well that the base face 12 is a right-angled trapezium with exactly two right-angled internal angles 18, and that these two right-angled internal angles 18 are located behind the other two internal angles of the trapezium in the transport direction 40. Figure 3 In addition, the projection 48 of the normal vector 44 of the first side 14 on the conveying surface 38 is indicated in b). It is particularly clear here that the angle 56 between the projection 48 of the normal vector 44 and the transport direction 40 is 30 degrees in this embodiment.

[0047] Figure 3 In addition, the projection 48 of the normal vector 44 of the first side 14 on the conveying surface 38 is indicated in b). It is particularly clear here that the angle 56 between the projection 48 of the normal vector 44 and the transport direction 40 is 30 degrees in this embodiment.

[0048] It can also be easily seen in the perspective from above that the lateral edge region 42 here exists on both sides of the center 46, and that the guiding bodies 10 are arranged in such a way that, in each case, a part of their base face 12 lies on the lateral edge region 42 and another part of the base face 12 lies above the conveying surface 38, in a similar manner to Figure 2 a). The guiding bodies 10 are also arranged on both sides of the center 46 of the conveying surface 38 in such a way that no guiding body 10 is arranged on the other side of the center 46, opposite each guiding body 10, in the direction perpendicular to the transport direction 40. Here, in addition, the guiding bodies 10 are also arranged uniformly offset.​

[0049] Figure 4 A further schematic view of a conveying device 34 according to a further embodiment of the application is shown. In this embodiment, the conveying device 34 has a conveying arrangement 36 and a plurality, here again four, guide bodies 10a, 10b, 10c, 10d. The guide bodies 10 are arranged in a manner similar to Figure 2 b) with their entire base surface 12 on the lateral edge region 42. The guide bodies 10 are also arranged in a manner similar to Figure 3 on both sides of the center 46 of the conveying surface 38, i.e. on the opposite side of each guide body 10, in a direction perpendicular to the transport direction 40, no guide body 10 is arranged on the other side of the center 46. Thus, as Figure 4 is shown, no guide body 10 is arranged opposite the guide body 10a. However, unlike the embodiment shown in Figure 3 , the guide bodies are not arranged uniformly offset in Figure 4 . Since it can be seen that the distance 58 between the guide body 10a and the guide body 10c is greater than the distance 60 between the guide body 10a and the guide body 10b.
