Abstract
According to the invention, in order to be able to create a vertical conveying section (9) of a vertical conveyor (1), with support rolls (21) on the conveyor belt (4) that roll on support elements (22), which is low maintenance and has a small cross-sectional area, a number of vertical support elements (31, 32) is arranged in a vertical conveying section (9) of the vertical conveyor (1) on either side of the top belt (11) and/or of the bottom belt (12) of the conveyor belt (4), first support rolls (2T) and second support rolls (21'') are arranged adjacent to one another in the longitudinal direction (x) on the conveyor belt (4) offset against one another by a transverse offset (V) and the first support rolls (2T) and second support rolls (21'') roll on the number of support elements (31, 32), so that the conveyor belt (4) in the vertical conveying section (9) deflects in the direction of the transverse offset (V) as the first support rolls (2T) and second support rolls (21'') roll against the number of support elements (31, 32) and the first support rolls (2T) and second support rolls (21'') thereby press against the number of support elements (31, 32).
Description
Vertical conveyor The present invention relates to a vertical conveyor having an endless conveyor belt on which a plurality of support rollers are arranged so as to be rotatably mounted and distributed in the longitudinal direction of the conveyor belt on both sides, wherein the support rollers for guiding the conveyor belt along a conveying path roll at least partly on support elements.
Continuous conveyors, for example conveyor belts, are well known for transporting materials.
In such continuous conveyors, an endless conveyor belt is guided over deflection pulleys, whereas a plurality of support roller usually being arranged between the two deflection pulleys in order to support the conveyor belt, either the top belt and possibly also the bottom belt. The top belt usually denotes the part of the conveyor belt on which the material to be conveyed comes to lie, while the bottom belt usually denotes the part of the conveyor belt in the region of the return. However, there are also continuous conveyors in which material is also conveyed on the bottom belt. At least one deflection pulley is arranged in a loading station and in an unloading station, between which the material is conveyed.
Also, continuous conveyors with a circulating conveyor belt are known, in which support roller are rotatably arranged on the conveyor belt, whereas the support roller rolling on support ropes which are stretched between two end points of the conveying path of the continuous conveyor. The advantage of such systems is to be seen in the fact that very large spans can be achieved with the support ropes, so that only a few supports are required for the support ropes along the conveying path. Even with such continuous conveyors, the conveyor belt is guided over deflection pulleys in the end stations. Examples of such continuous conveyors can be found in EP 1 538 112 B1, EP 1 338 531 B1 or EP 2 Bl.
Often it is also necessary to overcome a height difference in conveyor applications. In the case of large differences in height, vertical conveyors are used in particular, in which the conveyor belt is arranged so as to be substantially vertical, because they require a small base surface. Such vertical conveyors having very high conveying heights in the range of a few hundred meters are used, for example, in the mining field in order to convey material from the mine to the surface. Smaller conveying heights can be found, for example, in handling facilities, for example ship unloading devices in a port. With such vertical conveyors it is also possible to convey in both directions, for example in the case of handling facilities for goods or materials.
An example of a vertical conveyor can be found in US Pat. No. 5,392,897 A, which shows a vertical conveyor in which two conveyor belts are used which are arranged facing one another, so that the two upper runs touch one another in the vertical conveying section. The material to be conveyed is enclosed between the two upper runs and thereby conveyed vertically upwards. For this purpose, an upper run extends in a zigzag shape over supporting rollers, whereas the supporting rollers being connected to one another in the form of a chain.
When this arrangement in the form of a chain is stretched in the longitudinal direction, the associated upper run is thereby pressed against the opposite upper run in order to hold the material to be conveyed securely between the two upper runs.
A vertical conveyor is known from EP 1 102 715 B1, with a conveyor belt on which a plurality of carrier members for receiving conveyed goods are attached. The conveyor belt itself consists of a number of traction members and a number of guide ropes and is guided over a number of deflection pulleys and guide pulleys. Due to the sometimes very large length of the conveyor belt in the vertical region, a horizontal deflection (in this direction the conveyor belt has practically no rigidity) is possible and is problematic. This can lead to vibrations of the conveyor belt and the conveyor belt can also touch parts of the shaft in which it is arranged, which can result in damage to the conveyor belt or the shaft. Last but not least, such vibrations can also cause conveyed material to fall out of the conveyor belt and fall down in the shaft, which could also lead to damage and system downtime. In the vertical conveying region, therefore, EP 1 102 715 B1 provides guide pulleys and a guide housing in order to avoid a horizontal deflection of the conveyor belt.
With such vertical conveyors, a very deep vertical shaft in which the vertical conveyor is arranged may be required. However, the larger the necessary base surface of the vertical shaft, the more complex is its manufacture, for example by drilling the shaft.
If maintenance parts, such as guide elements as described in EP 1 102 715 B1, have to be arranged in the shaft, then these must of course be accessible to maintenance personnel, which increases the cost of such a vertical conveyor considerably. Apart from the relatively complex maintenance of such guide elements, a larger shaft is therefore also required from the outset.
It is therefore the object of the present invention to provide a vertical conveyor having the smallest possible cross-sectional area, which vertical conveyor can also be arranged in a shaft and which is as simple as possible to maintain.
According to the invention, this object is achieved in that a number of vertical support elements is arranged in a vertical conveying section of the vertical conveyor on either side of the top belt and/or of the bottom belt of the conveyor belt, in that adjacent first support rollers and second support rollers are arranged on the conveyor belt offset against one another by a transverse offset and in that the first support rollers and second support rollers roll on the number of support elements, so that the conveyor belt in the vertical conveying section deflects in the direction of the transverse offset as the first support rollers and second support rollers roll against the number of support elements, and thereby presses the first

It is therefore the object of the present invention to provide a vertical conveyor having the smallest possible cross-sectional area, which vertical conveyor can also be arranged in a shaft and which is as simple as possible to maintain.
According to the invention, this object is achieved in that a number of vertical support elements is arranged in a vertical conveying section of the vertical conveyor on either side of the top belt and/or of the bottom belt of the conveyor belt, in that adjacent first support rollers and second support rollers are arranged on the conveyor belt offset against one another by a transverse offset and in that the first support rollers and second support rollers roll on the number of support elements, so that the conveyor belt in the vertical conveying section deflects in the direction of the transverse offset as the first support rollers and second support rollers roll against the number of support elements, and thereby presses the first
-2-support roller and second support roller against the number of supporting elements. Due to the transverse offset of the support rollers, the conveyor belt (top belt or bottom belt) is deflected, whereby the offset support rollers are pressed against the number of supporting elements. This results in a reliable guidance of the conveyor belt in the vertical conveying section on the number of supporting elements, so that very large height differences in the range of a few hundred meters can be realized. The particular advantage of this embodiment, however, is that only the supporting elements need to be arranged in the vertical conveying section, so that practically no maintenance parts, which are all arranged on the conveyor belt itself, are required in the vertical conveying section.
This also makes it possible to manufacture the vertical conveying section with a very small cross-sectional area, which in turn keeps costs down.
In a first possible, simpler embodiment, a vertical supporting element is arranged on both sides and the first and second offset support rollers roll on this one supporting element. This means that only a single supporting element is required on both sides.
In a further advantageous embodiment, a first and a second vertical support element are arranged on both sides so that the deflection of the conveyor belt causes the first support rollers to roll only on the first supporting element and causes the second support rollers to roll only on the second supporting element.
With the same track width of the offset support rollers, the distance between the at least two supporting elements in the direction of the transverse offset is preferably greater than the diameter of the running surfaces of the first and second offset support rollers in order to prevent a support roller from being clamped between the two supporting elements.
In an advantageous embodiment, further support rollers are arranged between the adjacent first and second support rollers, which are arranged in transverse direction between the first and second offset support rollers. In the embodiment with two supporting elements per side, it can thus be achieved that these additional support rollers do not roll on supporting elements in the vertical conveying section, which reduces the wear and tear on these support rollers. For this purpose, it can also be provided that the diameter of the running surfaces of the further support rollers is different, preferably smaller, than the diameter of the running surfaces of the first and second support rollers arranged offset to one another.
In a simple embodiment, every nth support roll, with n 3, can be arranged offset by the transverse offset, so that the offset support rollers can be implemented very easily.
For a simple and safe decoupling of the offset support rollers in the region of the upper end and/or the lower end of the vertical conveying section, an expansion frame is preferably provided when using supporting ropes as supporting elements, which spaces apart two

Fig. 1 shows an application of a vertical conveyor 1 according to the invention in a mine by way of example. In the underground, at a first height level, a loading station 2 is provided at which conveyed goods to be conveyed, for example bulk goods, are loaded onto the circulating endless conveyor belt 4 of the vertical conveyor 1. How the conveyed goods are loaded onto the conveyor belt 4 is irrelevant to the invention. At a second height level, for example on the surface or also underground, an unloading station 3 is provided, at which the conveyed goods are unloaded from the conveyor belt 4. It is also unimportant for the invention how the conveyed goods are unloaded at the unloading station 3. The difference between the first height level and the second height level substantially results in the height difference that has to be overcome with the vertical conveyor 1. The endless conveyor belt 4 circulates between the loading station 2 and the unloading station 3, for which a first reversing pulley 5 is arranged in the region of the loading station 2 and a second reversing pulley 6 is arranged in the region of the unloading station 3, over which the conveyor belt 4 runs. At least one of the reversing pulleys 5, 6 is driven in a well-known manner in order to make the conveyor belt 4 rotate in a circle.
The conveying direction of the vertical conveyor 1, that is from bottom to top or vice versa, is arbitrary and depends only on the direction of rotation of the drive. It is also possible to convey either only in the top belt 11 or simultaneously in the top belt 11 and in the bottom belt 12. This can also be changed if necessary.

Fig. 1 shows an application of a vertical conveyor 1 according to the invention in a mine by way of example. In the underground, at a first height level, a loading station 2 is provided at which conveyed goods to be conveyed, for example bulk goods, are loaded onto the circulating endless conveyor belt 4 of the vertical conveyor 1. How the conveyed goods are loaded onto the conveyor belt 4 is irrelevant to the invention. At a second height level, for example on the surface or also underground, an unloading station 3 is provided, at which the conveyed goods are unloaded from the conveyor belt 4. It is also unimportant for the invention how the conveyed goods are unloaded at the unloading station 3. The difference between the first height level and the second height level substantially results in the height difference that has to be overcome with the vertical conveyor 1. The endless conveyor belt 4 circulates between the loading station 2 and the unloading station 3, for which a first reversing pulley 5 is arranged in the region of the loading station 2 and a second reversing pulley 6 is arranged in the region of the unloading station 3, over which the conveyor belt 4 runs. At least one of the reversing pulleys 5, 6 is driven in a well-known manner in order to make the conveyor belt 4 rotate in a circle.
The conveying direction of the vertical conveyor 1, that is from bottom to top or vice versa, is arbitrary and depends only on the direction of rotation of the drive. It is also possible to convey either only in the top belt 11 or simultaneously in the top belt 11 and in the bottom belt 12. This can also be changed if necessary.
-4-Deflection pulleys 7 and/or deflection regions 8 are usually also provided along the conveying path of the vertical conveyor 1 in order to adapt the orientation of the endless conveyor belt 4 to the requirements. In the illustrated embodiment, the conveyor belt 4 is aligned slightly obliquely upward in the region of the loading station 2. In a deflection region 8, the transition to a vertical conveying section 9 takes place, in which the top belt 11 of the conveyor belt 4 runs substantially vertically. In the region of the unloading station 3, a deflection of the top belt 11 of the conveyor belt 4 takes place again into a substantially horizontal orientation. The bottom belt 12 of the conveyor belt 4 is preferably returned substantially parallel to the top belt 11. Of course, the guidance of the conveyor belt 4 along the entire conveying path can also be designed differently, but at least one vertical conveying section 9 is present in the vertical conveyor 1.
In this connection and in the context of the invention, however, "vertical"
with regard to the alignment of the conveyor belt 4 in the vertical conveying section 9 is not to be understood strictly as vertical. The conveyor belt 4 can in principle also be inclined at a specific angle with respect to a vertical. With the desired very large height differences of a few hundred meters, however, every degree of inclination of the conveyor belt 4 can mean a necessary widening of the vertical conveying section 9 by a few meters. If the vertical conveying section 9 is drilled, this would increase the drilling costs significantly. The vertical conveying section 9 itself can, however, also be oriented obliquely with respect to a vertical line, whereby the cross-sectional area of the vertical conveying section 9 could again be kept small despite the obliquely oriented conveyor belt 4. However, here too there are manufacturing limits. For example, the technical drilling limit is about 700 inclination. Thus, in the context of the vertical conveyor according to the invention, "vertical" is understood to mean an alignment of the conveyor belt 4 of 20 around the vertical.
A cross section through the conveyor belt 4 is shown in Fig. 2. On the conveyor belt 4 in the longitudinal direction (which corresponds to the conveying direction of the conveyor belt 4) a plurality of crossbeams 20 are provided, which protrude over the width of the conveyor belt 4 and at the axial ends of which support rollers 21 are arranged so as to be rotatably mounted.
Running surfaces 23 of the support rollers 21 run on support elements 22, such as ropes, pipes, round bars, rails, etc., which are provided along the conveying path of the vertical conveyor 1. The axial distance between the running surfaces 23 determines the track width W of the support rollers 21, which of course corresponds to the support element track width of the support elements 22. On the conveyor belt 4, lateral boundary walls 24 are also arranged on both sides, which protrude from the conveyor belt 4 in order to create a channel-shaped receptacle for the conveyed goods. As the conveyor belt 4 is usually deflected several times along the conveying path, the boundary walls 24 are preferably designed so
In this connection and in the context of the invention, however, "vertical"
with regard to the alignment of the conveyor belt 4 in the vertical conveying section 9 is not to be understood strictly as vertical. The conveyor belt 4 can in principle also be inclined at a specific angle with respect to a vertical. With the desired very large height differences of a few hundred meters, however, every degree of inclination of the conveyor belt 4 can mean a necessary widening of the vertical conveying section 9 by a few meters. If the vertical conveying section 9 is drilled, this would increase the drilling costs significantly. The vertical conveying section 9 itself can, however, also be oriented obliquely with respect to a vertical line, whereby the cross-sectional area of the vertical conveying section 9 could again be kept small despite the obliquely oriented conveyor belt 4. However, here too there are manufacturing limits. For example, the technical drilling limit is about 700 inclination. Thus, in the context of the vertical conveyor according to the invention, "vertical" is understood to mean an alignment of the conveyor belt 4 of 20 around the vertical.
A cross section through the conveyor belt 4 is shown in Fig. 2. On the conveyor belt 4 in the longitudinal direction (which corresponds to the conveying direction of the conveyor belt 4) a plurality of crossbeams 20 are provided, which protrude over the width of the conveyor belt 4 and at the axial ends of which support rollers 21 are arranged so as to be rotatably mounted.
Running surfaces 23 of the support rollers 21 run on support elements 22, such as ropes, pipes, round bars, rails, etc., which are provided along the conveying path of the vertical conveyor 1. The axial distance between the running surfaces 23 determines the track width W of the support rollers 21, which of course corresponds to the support element track width of the support elements 22. On the conveyor belt 4, lateral boundary walls 24 are also arranged on both sides, which protrude from the conveyor belt 4 in order to create a channel-shaped receptacle for the conveyed goods. As the conveyor belt 4 is usually deflected several times along the conveying path, the boundary walls 24 are preferably designed so
-5-that they allow a certain longitudinal expansion or bending, for example as known corrugated edges or with slots which are spaced apart in the longitudinal direction.
Due to the guidance of the conveyor belt 4 over reversing pulleys 5, 6 and due to the boundary walls 24 on the conveyor belt 4, it may also be necessary to turn the conveyor belt 4 before a deflection, since the conveyor belt 4 on the side with the boundary walls 24 cannot be guided over a deflection pulley 7. In Fig. 1, for example, turning stations 10 are provided for this purpose, which can be designed as described in EP 1 338 531 B1, and which rotate the conveyor belt 4 by 1800 in the longitudinal direction.
On the conveyor belt 4, on the side of the boundary walls 24 and distributed over the length of the conveyor belt 4, a plurality of partition walls 25 can be provided between the boundary walls 24, in order to be able to hold the conveyed goods in the vertical conveying section 9.
Of course, the conveyor belt 4 can also be designed differently for receiving the conveyed goods.
Fig. 3 shows a detailed view of the region of the unloading station 3. This shows the drive 13 which drives the reversing pulley 6. It can also be seen that in the reversal region 8 for the top belt 11 of the conveyor belt 4, a large number of supporting rollers 14 are arranged in an arc to support the conveyor belt 4 over a large area and thus reduce the load on the top belt 11 of the conveyor belt 4, which is filled with conveyed goods. The support elements 22, for example tensioned ropes, on which the support rollers 21 of the conveyor belt 4 roll in the unloading station 3, are also indicated in Fig. 3. After turning by an angle of 180 , the bottom belt 12 can be deflected into the vertical conveying section 9 over a simple deflection pulley 7.
Fig. 4 shows the region of the loading station 2 in detail. Here, too, it can be seen that the heavily loaded top belt 11 of the conveyor belt 4 is preferably deflected over an arcuate, very elongated deflection region 8, while the bottom belt is deflected again over a deflection pulley 7. The deflection region 8 is designed, for example, with curved pipes 15 as support elements 22 which are arranged on a stationary structure, wherein the support rollers 21 of the conveyor belt 4 roll in the deflection region 8 on the curved pipes 15. In the deflection region 8, a plurality of support roller 21 should preferably roll simultaneously on a support element 22. Further support elements 22 are indicated, on which the support rollers 21 of the conveyor belt 4 roll in the loading station 2.
It should only be mentioned for the sake of completeness that the loading could also or additionally take place at the top and the unloading could also or additionally take place at the bottom, but this would not change anything in the present invention.
In order to safely guide the conveyor belt 4 in the vertical conveying section 9 and, in particular, to avoid a deflection of the conveyor belt 4 in a direction normal to the surface of
Due to the guidance of the conveyor belt 4 over reversing pulleys 5, 6 and due to the boundary walls 24 on the conveyor belt 4, it may also be necessary to turn the conveyor belt 4 before a deflection, since the conveyor belt 4 on the side with the boundary walls 24 cannot be guided over a deflection pulley 7. In Fig. 1, for example, turning stations 10 are provided for this purpose, which can be designed as described in EP 1 338 531 B1, and which rotate the conveyor belt 4 by 1800 in the longitudinal direction.
On the conveyor belt 4, on the side of the boundary walls 24 and distributed over the length of the conveyor belt 4, a plurality of partition walls 25 can be provided between the boundary walls 24, in order to be able to hold the conveyed goods in the vertical conveying section 9.
Of course, the conveyor belt 4 can also be designed differently for receiving the conveyed goods.
Fig. 3 shows a detailed view of the region of the unloading station 3. This shows the drive 13 which drives the reversing pulley 6. It can also be seen that in the reversal region 8 for the top belt 11 of the conveyor belt 4, a large number of supporting rollers 14 are arranged in an arc to support the conveyor belt 4 over a large area and thus reduce the load on the top belt 11 of the conveyor belt 4, which is filled with conveyed goods. The support elements 22, for example tensioned ropes, on which the support rollers 21 of the conveyor belt 4 roll in the unloading station 3, are also indicated in Fig. 3. After turning by an angle of 180 , the bottom belt 12 can be deflected into the vertical conveying section 9 over a simple deflection pulley 7.
Fig. 4 shows the region of the loading station 2 in detail. Here, too, it can be seen that the heavily loaded top belt 11 of the conveyor belt 4 is preferably deflected over an arcuate, very elongated deflection region 8, while the bottom belt is deflected again over a deflection pulley 7. The deflection region 8 is designed, for example, with curved pipes 15 as support elements 22 which are arranged on a stationary structure, wherein the support rollers 21 of the conveyor belt 4 roll in the deflection region 8 on the curved pipes 15. In the deflection region 8, a plurality of support roller 21 should preferably roll simultaneously on a support element 22. Further support elements 22 are indicated, on which the support rollers 21 of the conveyor belt 4 roll in the loading station 2.
It should only be mentioned for the sake of completeness that the loading could also or additionally take place at the top and the unloading could also or additionally take place at the bottom, but this would not change anything in the present invention.
In order to safely guide the conveyor belt 4 in the vertical conveying section 9 and, in particular, to avoid a deflection of the conveyor belt 4 in a direction normal to the surface of
-6-the conveyor belt 4 (also referred to as vertical direction z), according to the invention, at least one supporting element 31 for the top belt 11 and/or the bottom belt 12 is arranged on each side of the conveyor belt 4, which support element is oriented substantially vertically ( 200 around the vertical) in the vertical conveying section 9. The supporting element 31 can be a rigid structural part, such as a pipe, a rail, a rod, etc., or can also be designed as a tensioned rope. In a further embodiment, two supporting elements 31,32 are arranged on each side of the conveyor belt 4 so as to be substantially vertically ( 20 around the vertical) along the conveyor belt 4, as explained with reference to Fig. 5 to 9.
Fig. 5 shows part of the vertical conveying section 9, which is designed, for example, as an approximately circular, vertical bore 30. On the top belt 11 of the conveyor belt 4, the boundary walls 24 and the partition walls 25 can also be seen therein. In this exemplary embodiment, a first supporting element 31 and a second supporting element 32 are arranged vertically on both sides (viewed in the longitudinal direction x) for the top belt 11 and the bottom belt 12. The axial distance between the supporting elements 31, 32 on the two sides in the transverse direction y (transverse to the longitudinal direction x) preferably corresponds to the track width W of the support rollers 21 on the conveyor belt 4.
Two in the longitudinal direction x adjacent support rollers 21', 21" are arranged on the conveyor belt 4 offset to one another in a vertical direction z (normal to the longitudinal direction x and to the transverse direction y) by a transverse offset V, as shown in Fig. 6.
Support rollers distributed over the entire length of the conveyor belt 4 are arranged offset to one another. The transverse offset V between two adjacent support rollers 21', 21" does not always have to be the same. The vertical direction z is substantially normal to the surface of the conveyor belt 4. As a result of this transverse offset V of the support rollers 21', 21", which are arranged between the two supporting elements 31, 32, the conveyor belt 4 is deflected in the vertical conveying section 9 in the vertical direction z. Due to this deflection, the support rollers 21', 21" are pressed against the supporting elements 31, 32, wherein first support rollers 21' are pressed against the first support element 31 and second support rollers 21" which are offset by the transverse offset V are pressed against the second support element 32. This results in a defined guidance of the conveyor belt 4 in the vertical conveying section 9 between the two supporting elements 31, 32, not only in the longitudinal direction x, but also in the vertical direction z, and also in the transverse direction y.
The track width of the two supporting elements 31, 32, and thus also the track width of the assigned offset support rollers 21', 21", need not be the same. In the case of the same track width, the distance S between two supporting elements 31,32 on one side of the conveyor belt 4 is preferably greater than the diameter D', D" of the running surfaces 23 of the offset support rollers 21', 21" of the conveyor belt 4. The diameters D', D" of the running surfaces of the support rollers 21', 21" are preferably the same, but can also be different.
Fig. 5 shows part of the vertical conveying section 9, which is designed, for example, as an approximately circular, vertical bore 30. On the top belt 11 of the conveyor belt 4, the boundary walls 24 and the partition walls 25 can also be seen therein. In this exemplary embodiment, a first supporting element 31 and a second supporting element 32 are arranged vertically on both sides (viewed in the longitudinal direction x) for the top belt 11 and the bottom belt 12. The axial distance between the supporting elements 31, 32 on the two sides in the transverse direction y (transverse to the longitudinal direction x) preferably corresponds to the track width W of the support rollers 21 on the conveyor belt 4.
Two in the longitudinal direction x adjacent support rollers 21', 21" are arranged on the conveyor belt 4 offset to one another in a vertical direction z (normal to the longitudinal direction x and to the transverse direction y) by a transverse offset V, as shown in Fig. 6.
Support rollers distributed over the entire length of the conveyor belt 4 are arranged offset to one another. The transverse offset V between two adjacent support rollers 21', 21" does not always have to be the same. The vertical direction z is substantially normal to the surface of the conveyor belt 4. As a result of this transverse offset V of the support rollers 21', 21", which are arranged between the two supporting elements 31, 32, the conveyor belt 4 is deflected in the vertical conveying section 9 in the vertical direction z. Due to this deflection, the support rollers 21', 21" are pressed against the supporting elements 31, 32, wherein first support rollers 21' are pressed against the first support element 31 and second support rollers 21" which are offset by the transverse offset V are pressed against the second support element 32. This results in a defined guidance of the conveyor belt 4 in the vertical conveying section 9 between the two supporting elements 31, 32, not only in the longitudinal direction x, but also in the vertical direction z, and also in the transverse direction y.
The track width of the two supporting elements 31, 32, and thus also the track width of the assigned offset support rollers 21', 21", need not be the same. In the case of the same track width, the distance S between two supporting elements 31,32 on one side of the conveyor belt 4 is preferably greater than the diameter D', D" of the running surfaces 23 of the offset support rollers 21', 21" of the conveyor belt 4. The diameters D', D" of the running surfaces of the support rollers 21', 21" are preferably the same, but can also be different.
-7-The selected distance S and this transverse offset V and the resulting deflection of the conveyor belt 4 also ensure that an offset support roller 21', 21" rolls on one supporting element 31, 32 in a defined manner and suffers little wear. A support roller 21', 21" is therefore not clamped between two supporting elements 31, 32, which would result in an uncontrolled sliding of the support roller 21', 21" on one or both supporting elements 31, 32, which in turn would increase the wear considerably.
Fig. 6 shows the relationships in a greatly exaggerated manner. The lateral transverse offset V is usually in the range from 1 to 50 cm. That of course also depends on the size of the conveyor belt 4, since a larger transverse offset V can of course also be implemented on a larger conveyor belt 4. On the other hand, the transverse offset should of course be kept as low as possible in order to limit the forced deflection of the conveyor belt 4 in the vertical conveying section 9. The transverse offset V must, however, be so great that there is sufficient pretensioning of the conveyor belt 4 in the direction of the supporting elements 31, 32 in order to ensure reliable guidance. The distance between two adjacent, offset support rollers 21', 21" can also be varied depending on the requirements. Distances in the range from 5 to 200 m are typical. This transverse offset V does not interfere with the movement of the conveyor belt 4 in the conveying direction, not even in the conveying sections away from the vertical conveying section 9 or in the deflection regions 8. With such guidance of the conveyor belt 4, height differences in the range of a few hundred meters can be overcome with the vertical conveying section 9.
In principle, the directly adjacent support rollers 21', 21" on the conveyor belt 4 could each be offset to one another by a transverse offset V. However, this is not absolutely necessary for the guidance of the conveyor belt 4 in the vertical conveying section 9.
Between two support rollers 21', 21" offset to one another with transverse offset V, a number m of further support rollers 21 can therefore be arranged in the longitudinal direction x, which are arranged laterally (in the direction of transverse offset V) between the two offset support rollers 21', 21", as shown in Fig. 7a. A number of 1 to 20 further support rollers 21 are typically arranged between the support rollers 21', 21" which are offset to one another.
These support rollers 21 would not be in contact at all with the supporting elements 31, 32 in the vertical conveying section 9, which would reduce the wear on these support rollers 21 in the vertical conveying section 9. This means that m 0 applies to the further support rollers 21, with the first support roll 21' being immediately adjacent to the second support roll 21" in the case of m = 0 (Fig. 6). These further support rollers 21 could also have a different diameter D of the running surface, preferably a smaller diameter, than the diameter D', D" of the support rollers 21', 21" arranged offset to one another. However, the diameter D of the further support rollers 21 should be smaller than the distance S between two supporting elements 31, 32.
Fig. 6 shows the relationships in a greatly exaggerated manner. The lateral transverse offset V is usually in the range from 1 to 50 cm.

In principle, the directly adjacent support rollers 21', 21" on the conveyor belt 4 could each be offset to one another by a transverse offset V. However, this is not absolutely necessary for the guidance of the conveyor belt 4 in the vertical conveying section 9.
Between two support rollers 21', 21" offset to one another with transverse offset V, a number m of further support rollers 21 can therefore be arranged in the longitudinal direction x, which are arranged laterally (in the direction of transverse offset V) between the two offset support rollers 21', 21", as shown in Fig. 7a. A number of 1 to 20 further support rollers 21 are typically arranged between the support rollers 21', 21" which are offset to one another.
These support rollers 21 would not be in contact at all with the supporting elements 31, 32 in the vertical conveying section 9, which would reduce the wear on these support rollers 21 in the vertical conveying section 9. This means that m 0 applies to the further support rollers 21, with the first support roll 21' being immediately adjacent to the second support roll 21" in the case of m = 0 (Fig. 6). These further support rollers 21 could also have a different diameter D of the running surface, preferably a smaller diameter, than the diameter D', D" of the support rollers 21', 21" arranged offset to one another. However, the diameter D of the further support rollers 21 should be smaller than the distance S between two supporting elements 31, 32.
-8-In this embodiment, the support rollers 21', 21" arranged offset to one another could also have a different track width than the further support rollers 21 arranged between them. In this way, the conveyor belt 4 would preferably only be guided on the further support rollers 21 away from the vertical conveying section 9 and not on the support rollers 21', 21" which are .. arranged offset to one another. With a different track width, the diameter D of the support rollers 21 could even be greater than the distance S between two supporting elements 31, 32.
In a further possible embodiment, every nth support roller 21", with n 3, could be offset by a transverse offset V with respect to other support rollers 21', as shown in Fig. 7b. In this case there are no further support rollers 21 between them. The track width W
of the support rollers 21', 21" would preferably, but not necessarily, be the same.
The same effect can also be achieved with only one supporting element 31, as will be described with reference to Fig. 10. Here, only one supporting element 31 is arranged on each side of the conveyor belt 4. The support rollers 21', 21" on the conveyor belt 4 are again arranged offset to one another by a transverse offset V. The support rollers 21, 21" are guided on the support element 31 in such a way that the contact points of the running surfaces of the offset support rollers 21', 21" with the supporting element 31 face each other, i.e., the supporting element 31 is arranged in the vertical direction z between the offset support rollers 21', 21". Due to the transverse offset V, the conveyor belt 4 is deflected again and reliable guidance is achieved again in that the support rollers 21', 21"
are pressed against the supporting element 31. In this embodiment, too, further support rollers 21 can be arranged between the offset support rollers 21', 21", as already described above with reference to Fig. 7a. An embodiment as described with Fig. 7b is of course also conceivable.
In the same way, the offset support rollers 21', 21" can again have different track widths than other support rollers 21, just as the diameters D, D', D" can be the same or different. The specification on the transverse offset V and the number of further support rollers 21 also applies in the same way to this embodiment.
In conveying sections other than the vertical conveying section 9, for example in horizontal or approximately horizontal conveying sections, and in particular also in the deflection regions 8, the conveyor belt 4 would, however, preferably be supported on the associated support elements 22 by all the support rollers 21, 21', 21" present, which reduces the load on the individual support rollers 21, 21', 21". If the offset support rollers 21', 21" have a different track width than the further support rollers 21 in between, then the support would preferably only take place with the further support rollers 21.
In a further possible embodiment, every nth support roller 21", with n 3, could be offset by a transverse offset V with respect to other support rollers 21', as shown in Fig. 7b. In this case there are no further support rollers 21 between them. The track width W
of the support rollers 21', 21" would preferably, but not necessarily, be the same.
The same effect can also be achieved with only one supporting element 31, as will be described with reference to Fig. 10. Here, only one supporting element 31 is arranged on each side of the conveyor belt 4. The support rollers 21', 21" on the conveyor belt 4 are again arranged offset to one another by a transverse offset V. The support rollers 21, 21" are guided on the support element 31 in such a way that the contact points of the running surfaces of the offset support rollers 21', 21" with the supporting element 31 face each other, i.e., the supporting element 31 is arranged in the vertical direction z between the offset support rollers 21', 21". Due to the transverse offset V, the conveyor belt 4 is deflected again and reliable guidance is achieved again in that the support rollers 21', 21"
are pressed against the supporting element 31. In this embodiment, too, further support rollers 21 can be arranged between the offset support rollers 21', 21", as already described above with reference to Fig. 7a. An embodiment as described with Fig. 7b is of course also conceivable.
In the same way, the offset support rollers 21', 21" can again have different track widths than other support rollers 21, just as the diameters D, D', D" can be the same or different. The specification on the transverse offset V and the number of further support rollers 21 also applies in the same way to this embodiment.
In conveying sections other than the vertical conveying section 9, for example in horizontal or approximately horizontal conveying sections, and in particular also in the deflection regions 8, the conveyor belt 4 would, however, preferably be supported on the associated support elements 22 by all the support rollers 21, 21', 21" present, which reduces the load on the individual support rollers 21, 21', 21". If the offset support rollers 21', 21" have a different track width than the further support rollers 21 in between, then the support would preferably only take place with the further support rollers 21.
-9-In a practical embodiment, the offset support rollers 21', 21" on the conveyor belt 4 could be arranged in the longitudinal direction x at a distance of approximately 50 m.
In between, for example, five further support rollers 21 could be provided.
Fig. 8 and 9 explain how the supporting elements 31, 32 can be arranged in the vertical conveying section 9 when they are designed as ropes.
At the upper end of the vertical conveying section 9 (Fig. 8) an upper anchor frame 40 is arranged, to which the ends of the rope-shaped supporting elements 31, 32 are clamped. For this purpose, of course, corresponding tensioning devices can also be provided for the supporting elements 31, 32. At the end of the vertical conveying section 9, the conveyor belt 4 must of course be decoupled from the guidance of the supporting elements 31, 32. For this purpose, an expansion frame 41 can be arranged in the region of the upper end of the vertical conveying section 9, which brings the supporting elements 31, 32 from the distance S in the vertical conveying section 9 to a greater distance S'. At the same time, the expansion frame 41 can guide the supporting elements 31, 32 on both sides from the track width W laterally in the transverse direction y further apart from one another (as can be seen, for example, in Fig. 3). Such an expansion frame 41 is preferably arranged on each side of the conveyor belt 4. Thereby, the support rollers 21', 21" are decoupled from the supporting elements 31, 32 and all support rollers 21, 21', 21" can subsequently be coupled to support elements 22 in the other conveying sections of the conveying path. If a turning station 10 is provided, for example on the down running bottom belt 12 of the conveyor belt 4, then the conveyor belt 4 in the turning station 10 is of course guided therein and the supporting elements 31, 32 are only then brought to the distance S and the correct track width W, for which a corresponding expansion frame 41 can again be provided.
The lower end of the vertical conveying section 9, as shown in Figure 9, is of course designed alike. A lower anchor frame 50 is provided, to which the opposite ends of the rope-shaped supporting elements 31, 32 are clamped. Corresponding tensioning devices can of course also be provided for the supporting elements 31, 32, with a tensioning device at the top or bottom usually being sufficient. In the same way, an expansion frame 51 is provided in order to decouple the support rollers 21', 21" at the end of the vertical conveying section 9 from the supporting elements 31, 32. Such an expansion frame 51 is preferably arranged on each side of the conveyor belt 4. On the top belt 11 running up, the supporting elements 31, 32 are of course only brought to the correct distance S and to the correct track width W after the deflection region 8, for which a corresponding expansion frame 51 can again be provided.
The coupling and decoupling of the support rollers 21, 21', 21" of the conveyor belt 4 is of course carried out in an analogous manner in the case of rigid supporting elements 31, 32.
In between, for example, five further support rollers 21 could be provided.
Fig. 8 and 9 explain how the supporting elements 31, 32 can be arranged in the vertical conveying section 9 when they are designed as ropes.
At the upper end of the vertical conveying section 9 (Fig. 8) an upper anchor frame 40 is arranged, to which the ends of the rope-shaped supporting elements 31, 32 are clamped. For this purpose, of course, corresponding tensioning devices can also be provided for the supporting elements 31, 32. At the end of the vertical conveying section 9, the conveyor belt 4 must of course be decoupled from the guidance of the supporting elements 31, 32. For this purpose, an expansion frame 41 can be arranged in the region of the upper end of the vertical conveying section 9, which brings the supporting elements 31, 32 from the distance S in the vertical conveying section 9 to a greater distance S'. At the same time, the expansion frame 41 can guide the supporting elements 31, 32 on both sides from the track width W laterally in the transverse direction y further apart from one another (as can be seen, for example, in Fig. 3). Such an expansion frame 41 is preferably arranged on each side of the conveyor belt 4. Thereby, the support rollers 21', 21" are decoupled from the supporting elements 31, 32 and all support rollers 21, 21', 21" can subsequently be coupled to support elements 22 in the other conveying sections of the conveying path. If a turning station 10 is provided, for example on the down running bottom belt 12 of the conveyor belt 4, then the conveyor belt 4 in the turning station 10 is of course guided therein and the supporting elements 31, 32 are only then brought to the distance S and the correct track width W, for which a corresponding expansion frame 41 can again be provided.
The lower end of the vertical conveying section 9, as shown in Figure 9, is of course designed alike. A lower anchor frame 50 is provided, to which the opposite ends of the rope-shaped supporting elements 31, 32 are clamped. Corresponding tensioning devices can of course also be provided for the supporting elements 31, 32, with a tensioning device at the top or bottom usually being sufficient. In the same way, an expansion frame 51 is provided in order to decouple the support rollers 21', 21" at the end of the vertical conveying section 9 from the supporting elements 31, 32. Such an expansion frame 51 is preferably arranged on each side of the conveyor belt 4. On the top belt 11 running up, the supporting elements 31, 32 are of course only brought to the correct distance S and to the correct track width W after the deflection region 8, for which a corresponding expansion frame 51 can again be provided.
The coupling and decoupling of the support rollers 21, 21', 21" of the conveyor belt 4 is of course carried out in an analogous manner in the case of rigid supporting elements 31, 32.
-10-Here too, if necessary, the distance S, and possibly the track width W, is changed accordingly in order to couple or decouple the support rollers 21, 21', 21"
to/from the supporting elements 31, 32.
A considerable advantage of this embodiment of a vertical conveying section 9 is that no maintenance parts have to be arranged in the vertical conveying section 9.
This makes it possible to design the vertical conveying section 9 with a very small cross section, which significantly reduces the cost of manufacturing the vertical conveying section 9. When erecting the vertical conveyor 1, only the supporting elements 31, 32 are to be arranged in the vertical conveying section 9, for example by lowering ropes, which are arranged on the upper anchor frame 40, and clamping them on the accessible lower anchor frame 50. The assembly of rigid supporting elements 31, 32 in the vertical conveying section 9 can also be carried out easily. The conveyor belt 4 can also simply be lowered or pulled up, wherein the existing guidance with the support rollers 21, 21', 21", support elements 22, and supporting elements 31, 32 ensures that the conveyor belt 4 can be threaded safely.
