Description

[0001] The invention relates to a belt conveyor device.

[0002] Prior art has revealed belt conveyor devices for conveying various types of goods, in which one or more belts are moved by means of deflection pulleys and corresponding drives that either drive the deflection pulleys or the belt directly. The goods can be arranged on the upper side of the belt and are transported or conveyed by the movement of the belt along a conveying path.

[0003] The conveying path, especially in larger belt conveyor systems, is not exclusively straight, but typically includes curves, bends, inclines, and / or declines. At these points, the conveyed material is usually transported by sequentially arranged sections, each with its own separate belt and drive. This results in a complex design for the belt conveyor systems, requiring a large number of components.

[0004] The invention is therefore based on the objective of providing a belt conveyor device with a simplified design.

[0005] The problem according to the invention is solved by a belt conveyor device comprising a movable belt on which conveyed goods can be moved along a conveying path, wherein the conveying path has at least a first conveying path section and at least a second conveying path section, wherein the belt runs continuously between the first and the second conveying path section, and further comprising at least a first deflection device for deflecting and guiding the belt around an area between the first and the second conveying path section, in which a functional module can be arranged, wherein the conveyed goods can be moved in the area of ​​the functional module between the first conveying path section and the second conveying path section by means of the functional module and / or for deflecting and guiding the belt at a position along the conveying path.where the first conveying path section and the second conveying path section are arranged at an angle, at least with respect to a horizontal plane.

[0006] An angle relative to a horizontal plane is, in particular, an angle at which the two conveying path sections are arranged such that the conveyed material moves in a horizontal direction. The horizontally angled arrangement or movement can, in particular, be angled to the left or right. Specifically, the two conveying path sections need not be arranged at an angle that lies exclusively in a horizontal plane; the angle can also extend vertically. The resulting movement or trajectory of the conveyed material on the first and second conveying path sections can therefore include directional components in both horizontal and vertical directions. In particular, the first and second conveying path sections can also be arranged entirely in a horizontal plane.

[0007] The conveying path is, in particular, the portion of the conveyor belt on which the conveyed goods are arranged. Specifically, the conveying path is not the same as the belt length. The belt length refers to the complete path of the conveyor belt. Accordingly, the conveying path is generally shorter than the belt length, as it can also include areas outside the conveying path where the conveyor belt is redirected or retracted in sections. The conveying path can be formed solely by the conveyor belt or a material support surface of the conveyor belt, or by conveying path segments within the functional module.

[0008] The conveyor belt is designed as a continuous, i.e., a single, continuous element, while the conveying path can consist of several separate conveying path sections. The conveyor belt has no openings, and the conveyed material is not transported on two separate conveyor belts in the first and second conveying path sections. Rather, the conveyed material, which is transported sequentially in the first and second conveying path sections, is first transported on a first conveyor belt section and then on a second conveyor belt section of the same belt, spaced apart from the first. In particular, the conveyor belt runs continuously between and through the first and second conveying path sections.The separate conveyor path sections can be connected to form a continuous, in particular self-contained, conveyor path by directly connecting two conveyor belt sections or by conveyor path sections in the functional module.

[0009] The belt conveyor device is in particular a flat belt conveyor or a flat belt conveyor.

[0010] Preferably, the first deflection device comprises at least a first deflection roller for deflecting the belt from the conveying path and a second deflection roller for feeding the belt to the conveying path.

[0011] Preferably, the first and second deflection pulleys are arranged parallel to each other with respect to their axes of rotation. Preferably, the first and second deflection pulleys are arranged in the same horizontal plane or in different horizontal planes.

[0012] By arranging the first and second deflection rollers in different horizontal planes, i.e. at different heights, it is possible, in the case that a functional module is arranged between the first and second conveying path sections, to simultaneously convey the conveyed material in the vertical direction, which is then carried out in particular by the functional module.

[0013] Preferably, the direction of the conveying path is changed by arranging the first and second conveying path sections at the angle between the first and second deflection rollers. For this purpose, the first and second deflection rollers are preferably arranged at an angle, for example 45° for a 90° change in the direction of the conveying path, to a longitudinal axis or centerline of the belt.

[0014] Furthermore, the first and second deflection rollers are arranged, in particular, in the region of the apex of the angle between the first and second conveyor belt sections. The change of direction, at least in the horizontal plane of the conveyed material's movement, thus occurs between the first and second deflection rollers. The conveyed material is transferred from the first to the second conveyor section, particularly in the region of the first and second deflection rollers. Between the first and second deflection rollers, the conveyor belt is preferably guided outside the conveying path in such a way that any difference in path length between two opposing points on the respective side edges of the conveyor belt, which are located at the same position relative to the conveying path before impacting the first or second deflection roller, is compensated for by the belt's angled guidance.This is achieved in particular by means of one or more additional deflection pulleys, as will be explained in detail below.

[0015] Preferably, the functional module is positioned between the first and second deflection rollers. Transfer to and receipt from the functional module within the first and second conveyor sections occurs specifically in the area of ​​the first and second deflection rollers. The first and second deflection rollers ensure that the conveyor belt can be guided away from and around the functional module, while the conveyed material is fed to the functional module and conveyed further by it, and not by the conveyor belt. Onward transport on the conveyor belt then takes place again within the first and second conveyor sections.

[0016] Preferably, the first deflection device comprises at least a third deflection roller, which is arranged between the first and second deflection rollers with respect to the belt path. The third deflection roller enables the belt to be guided around the functional module and / or compensates for the difference in path length between the points on the belt's side edges when the belt changes direction during conveying. The third deflection roller is, in particular, arranged outside the conveying path or in a different plane than the conveying path.

[0017] Preferably, the third deflection roller is arranged parallel to the first and / or the second deflection roller. This is particularly the case when the conveyor belt is guided around the functional module by means of the third deflection roller, but otherwise no changes in direction, especially with respect to a horizontal plane, occur in the conveying path between the first and second conveying path sections. For example, starting from the first conveying path section, the conveyor belt can be guided from the first deflection roller to the third deflection roller and then from the third deflection roller to the second deflection roller and the second conveying path section.

[0018] Preferably, the first deflection device comprises at least a fourth deflection pulley, which is arranged parallel to the first and / or second deflection pulley. The fourth deflection pulley can preferably also be arranged parallel to the third deflection pulley. Furthermore, the fourth deflection pulley can be arranged between the third deflection pulley on the one hand and the first or second deflection pulley on the other. Preferably, further deflection pulleys can be provided, which are particularly arranged parallel to the first, second, third, and / or fourth deflection pulleys and over which the webbing is guided successively in order to create differently shaped deflection sections for the webbing, thus advantageously enabling the webbing to be deflected around functional modules of different shapes or sizes.

[0019] Preferably, the third deflection roller is arranged obliquely relative to the first and second deflection rollers. The third deflection roller thus has a tilt relative to the first and second deflection rollers, the tilt being particularly with respect to at least one vertical plane. When viewed in the direction of the conveying path, the third deflection roller is particularly inclined laterally, i.e., downwards to the left or right. Preferably, the deflection roller has a first and a second end, with the first and second ends being inclined downwards relative to the other end. This tilt ensures that any difference in path length between two opposing points on the side edge of the belt, caused by the oblique position of the first and second deflection rollers relative to the longitudinal axis or centerline of the belt, is compensated for, so that the points reach the first and second ends respectively.The second deflection pulley is always opposite each other with respect to the center line of the webbing, so that the webbing retains its flat position.

[0020] Preferably, the first deflection device comprises at least a fourth deflection pulley, which is arranged obliquely relative to the first, second, and third deflection pulleys. The webbing is preferably guided between the first and second deflection pulleys over the third and fourth deflection pulleys. The inclinations of the third and fourth deflection pulleys are selected, in particular, to compensate for the aforementioned difference in the webbing's path length. Preferably, the third and fourth deflection pulleys are arranged in the same horizontal plane, but within this plane, they are preferably arranged obliquely or not parallel to each other. The provision of the fourth deflection pulley allows the webbing to be deflected in a more compact area.

[0021] Preferably, the first and second conveyor belt sections are directly adjacent to each other along the conveying path. In particular, this ensures that the conveyed material is transferred directly from the first to the second conveyor belt section.

[0022] Preferably, the third and / or fourth deflection roller(s) are arranged below a plane in which the first and / or second deflection roller(s) are arranged. The third and fourth deflection rollers thus ensure that the conveyor belt is deflected and guided outside the conveying path, and particularly in those areas where there is no conveyed material on the belt.

[0023] Preferably, the third and / or fourth deflection pulley(s) are arranged along the belt path between the first and second deflection pulleys. The first and second deflection pulleys thus represent the points where the belt briefly or sectionally leaves the conveying path and, after being guided by the third or fourth deflection pulley, is returned to the conveying path. The belt path is significantly longer than the conveying path, particularly in this area.

[0024] Preferably, the third and fourth deflection pulleys are arranged in the same, in particular horizontal, plane.

[0025] Preferably, the belt conveyor has a direction adjustment device designed such that the angle by which the direction changes between the first and second conveying path sections can be changed. This angle is, in particular, at least the angle with respect to a horizontal plane by which the belt is deflected by the first deflection device. Advantageously, different conveying path profiles can be easily implemented with a single belt conveyor using the direction adjustment device.

[0026] Preferably, the direction adjustment device is designed to adjust the relative position of the first and second deflection rollers to each other and / or to adjust the relative position of the first and second deflection rollers to the third and / or fourth deflection rollers and / or to adjust the relative position of the third and fourth deflection rollers to each other. In other words, adjusting the deflection rollers accordingly allows for compensation of different belt pitch variations resulting from the variable angular positions of the first and second conveyor sections relative to each other.

[0027] Preferably, the belt conveyor device includes, in particular, a drive unit for driving the belt. Because the same belt is used even across discontinuous sections of the conveying path, such as areas of change of direction or interruptions caused by functional modules, the number of separate belts required, each typically requiring its own drive, can be reduced. In particular, only a single belt, driven by exactly one drive unit, can be provided. This significantly simplifies the design of the belt conveyor device and reduces the number of components required.

[0028] Preferably, the drive unit is designed to drive at least one deflection roller of the belt conveyor. The remaining deflection rollers of the belt conveyor are preferably driven passively by static friction with the belt.

[0029] Preferably, the drive device is designed to drive a third deflection pulley, which is positioned between a first deflection pulley that guides the belt away from the conveyor belt towards the third deflection pulley and a second deflection pulley that guides the belt from the third deflection pulley back to the conveyor path. This third deflection pulley is thus specifically intended solely for driving the belt.

[0030] Preferably, especially in the case of larger belt conveyors, several drive units may be provided. In this case, the belt conveyor comprises at least two, and in particular at least three or four, drive units for driving the belt.

[0031] Preferably, each of the drive devices is designed to drive at least one deflection roller of the belt conveyor device.

[0032] Preferably, if the first deflection pulley has a drive device by means of which it is driven, the second deflection pulley does not have a drive device.

[0033] Preferably, the drive unit(s) for operating the conveyor belt in reversing mode are designed with a first conveying direction and a second conveying direction opposite to the first. In other words, the conveyor belt is preferably movable forwards and backwards.

[0034] Preferably, the belt conveyor device has exactly one belt.

[0035] Preferably, the conveyor belt is designed as a closed loop with a first side that forms the support surface for the conveyed material and a second side facing away from the first, which forms the underside of the belt. Within the conveying path, the first side is preferably always oriented upwards. In the closed configuration, the conveyor belt particularly forms a ring. The closed design of the conveyor belt has the advantage that no return guide for the conveyor belt is necessary and, in particular, no slack side needs to be provided. This further simplifies the design of the conveyor belt device.The closed form of the webbing is made possible in particular by the fact that at discontinuous points, such as in areas of changes in direction or interruptions by functional modules, it is possible to continue using the first deflection device and that no change between separate webbing is necessary at this point.

[0036] Preferably, the belt conveyor has several, in particular two, three, four, five, or six, deflection devices for deflecting and guiding the belt in a gap between the first and second conveying path sections and / or for deflecting and guiding the belt at a position along the conveying path where a change of direction occurs between the first and second conveying path sections in a horizontal plane. The additional deflection devices are preferably identical or different to the first deflection device.

[0037] Preferably, the first deflection device for deflecting and guiding the conveyor belt is configured at a position along the conveying path where the first and second conveyor sections are arranged at an angle, at least with respect to a vertical plane. This allows for a vertical change in the direction of the conveyor path in addition to deflecting the belt in a horizontal plane. A change in direction solely in the vertical direction, i.e., particularly upwards or downwards, is also possible.

[0038] Preferably, the belt conveyor device comprises at least a second deflection device for deflecting and guiding the belt at a position along the conveying path where the first conveying path section or the second conveying path section and a third conveying path section are arranged at an angle at least with respect to a vertical plane.

[0039] The change in direction in the vertical direction can be achieved, in particular, by an inclined path for the first or second section of the conveyor. In the simplest case, a third deflection pulley is positioned between the first and second deflection pulleys, parallel to the first and second. The conveyor belt is then guided from the first or second deflection pulley away from the conveyor to the third deflection pulley and subsequently back to the first or second deflection pulley and onto the conveyor. This deflection via the third deflection pulley thus prevents the conveyor belt from kinking or buckling in the area of ​​the kink in the conveyor path caused by the vertical change in direction.

[0040] The first and second deflection pulleys are typically positioned directly next to each other, allowing the conveyed material to move directly from the first to the second conveyed section. Alternatively, the first and second deflection pulleys can be spaced apart and, if necessary, positioned at different heights, for example, if a change in vertical direction, possibly with a simultaneous change in height, is only required after the conveyed material has passed through a functional module. In this case, the third deflection pulley redirects the conveyor belt around the functional module. Additional deflection pulleys may also be used for this purpose.

[0041] Preferably, the functional module is arranged between the first and second conveyor sections, with the conveyor path running through the functional module between the first and second conveyor sections. In this case, the functional module forms part of the belt conveyor system.

[0042] Preferably, the functional module comprises a detection device, particularly an optical one, for detecting the conveyed material, a sorting device for sorting the conveyed material, an infeed and / or outfeed device for introducing and / or removing conveyed material onto and / or from the conveying path, and / or a treatment device for treating the conveyed material. If the functional module is an optical detection device, it may preferably include at least one camera and / or sensors for counting and / or quality control of the conveyed material. Furthermore, the detected conveyed material can be sorted. For this purpose, a sorting unit can be provided either in the same functional module or in a separate one. Additionally, the conveyed material can be treated.

[0043] The invention will now be explained in more detail using exemplary embodiments. These show Fig. 1.

[0044] Fig. Figure 1 shows a section of a belt conveyor device 100. A first conveying path section 11 and a second conveying path section 12 are shown, each carrying a belt 10 (not shown). The first conveying path section 11 and the second conveying path section 12 are arranged at an angle WH to each other with respect to a horizontal plane. Accordingly, conveyed material moving on the two conveying path sections 11 and 12 is deflected by the angle WH. An opening 20 is arranged between the two conveying path sections 11 and 12, through which the belt can be guided downwards, the belt being guided by means of two Fig. The material is guided downwards by one deflection roller (not shown) and then back upwards onto the conveyor path. The two deflection rollers are part of a first deflection device 13a.

[0045] Fig. Figure 2a shows a perspective view of a belt conveyor 100 with several points of horizontal and vertical change of direction PH1, PH2, PV1, PV2. The belt conveyor 100 comprises several conveyor sections 11, 12 arranged in series. Three conveyor sections 11, 12 are arranged in a horizontal plane, with the conveyor sections 11, 12 being arranged at an angle to each other. The angles between the respective conveyor sections 11, 12 are each greater than 90°. At the points of horizontal change of direction PH1, PH2, a deflection device 13a, 13b is arranged. Fig. 2a shows in particular that by means of the belt conveyor device 100 both horizontal and vertical changes in direction of the belt 10 are possible with a continuous belt.

[0046] Fig. Figure 2b shows the belt 10 of the belt conveyor device 100. Fig. 2a. The course of the webbing 10 is shown in particular in those areas where the webbing 10 is guided through the deflection devices 13a, 13b, 13e, 13f. A detailed view of the course of the webbing 10 in one of the deflection devices 13a, 13b for the horizontal change of direction is also shown in Fig. 5 shown. Fig. Figure 2b does not show the individual deflection pulleys of the deflection devices 13a, 13b, 13e, 13f; however, these are essentially arranged at every point where the conveyor belt 10 changes direction along the conveying path and runs in a kink or loop. Furthermore, a drive device 19 can be arranged at position 20, which drives a deflection pulley that can be arranged within the conveyor belt loop shown there.

[0047] The belt 10 of the embodiment of the belt conveyor device 100 made of Fig. 2a, Fig. 2b is constructed in one piece, and the belt conveyor device 100 in particular has a single belt 10, which is designed as a closed unit. In the Fig. 2a and Fig. 2b The circuit formed by the closed shape of the belt 10 comprises a loaded section, which includes the conveying path along which the conveyed material is moved on the belt 10, and an unloaded section arranged below the loaded section, in which the belt 10 returns. An alternative embodiment of a closed belt 10, in which the circuit formed by the closed shape of the belt 10 constitutes a circular or closed conveying path in which the conveyed material can be continuously transported in a closed path, is described in Fig. 6 shown. In the Fig. In the embodiment shown in Figure 6, the conveying path or the load side of the belt 10 is closed, so that an unloaded side can advantageously be omitted. The configuration of the belt 10 from Fig. 2b does have an empty section, since the conveying path has a start and an end point, however, this is formed by a single, continuous belt 10 and, in particular, separate belt sections and thus separate empty section sections are not necessary in the individual conveying path sections 11, 12.

[0048] Fig. Figure 3 shows the first deflection device 13a according to a first embodiment and the belt 10 guided and deflected by means of the deflection device 13a. The first deflection device 13a comprises a first deflection roller 14a and a second deflection roller 14b, by means of which the belt can be guided away from and back to the conveyor path. A third deflection roller 15a of the first deflection device 13a is arranged between the first and second deflection rollers 14a and 14b, relative to the belt path.

[0049] While the first and second deflection rollers 14a, 14b are arranged parallel to each other, the third deflection roller 15a is arranged at an angle to both the first and second deflection rollers 14a, 14b. In particular, the third deflection roller 15a runs at an angle in a vertical plane. This angled arrangement compensates for any difference in the belt's path length caused by the arrangement of the first and second conveyor sections 11, 12 at an angle to each other.

[0050] Fig. Figure 3 further shows additional deflection devices 13b, 13c, which are essentially identical and each have first, second and third deflection rollers 14a, 14b, 15a. The three deflection devices 13a, 13b, 13c connect four conveyor sections 11, 11a, 12, 12a, which are arranged in a row at a horizontal angle to each other, and guide the belt 10 accordingly around a curve.

[0051] Fig. Figure 4 shows a view of the underside of the webbing 10 or the deflection device 13a. The inclined arrangement of the third deflection pulley 15a relative to the first and second deflection pulleys 14a, 14b of the individual deflection devices 13a, 13b, 13c can be seen.

[0052] Fig. Figure 5 shows a detailed view of a section of the webbing 10, which is deflected and guided by a deflection device 13a according to a second embodiment. In this embodiment, a third deflection pulley 15a, which is not shown for clarity, is arranged in a horizontal plane, unlike in the previously described embodiment, where it is not arranged at an angle to the first and second deflection pulleys 14a and 14b in a vertical plane. The first deflection pulley 14a is located at position P1. Furthermore, a fourth deflection pulley 15b, also not shown, is provided, which is arranged between the third deflection pulley 15a and the second deflection pulley 14b with respect to the length of the webbing. The second deflection pulley 14b is located at position P2, the third deflection pulley 15a at position P3, and the fourth deflection pulley 15b at position P4.The fourth deflection pulley 15b, like the third deflection pulley 15a, is arranged at an angle to the first and second deflection pulleys 14a and 14b when viewed in a horizontal plane. Furthermore, the third and fourth deflection pulleys 15a and 15b are arranged at an angle to each other when viewed in a horizontal plane.

[0053] Fig. Figure 5 further shows that the belt 10 is additionally guided in a slack section on the underside of the belt conveyor device 100. This can alternatively be omitted if the belt 10 is designed as a closed loop.

[0054] A belt conveyor device 100 with a correspondingly closed belt 10 is in Fig. Figure 5 shows that the closed shape of the webbing 10 is achieved by deflecting the webbing 10 at positions of horizontal change of direction PH1, PH2, PH3, PH4. Furthermore, the webbing 10 is deflected vertically at positions of vertical change of position PV1, PV2. Deflection devices 13a to 13h are arranged at each of the positions PH1, PH2, PH3, PH4, PV1, PV2.

[0055] Another deflection device 13i is located in the area of ​​a receiving chamber 16 for a Fig. 6 Functional module not shown provided for redirecting the belt 10 around the receiving space 16. Fig. Figure 6 further shows a configuration of the belt conveyor 100 in which the belt 10 is designed as a closed loop. The closed configuration is made possible by the provision or sequential arrangement of several conveying path sections 11, 11a, 12, 12a. At least some of the conveying path sections 11, 11a, 12, 12a are arranged at an angle to a horizontal plane, thus forming a closed conveying path. For example, as shown in Fig. Figure 6 shows four deflection devices 13a to 13d, each enabling a deflection of the conveyed material or a horizontal change in the direction of the conveying path by 90° at positions PH1 to PH4, thus forming a closed conveying path, in particular without an empty section. The closed configuration can generally also be achieved with an alternative selection of deflection devices. For example, more or fewer deflection devices can be provided, and these can each bring about a different deflection of the conveyed material or a different change in the direction of the conveying path, in particular more or less than 90°.

[0056] Furthermore, along the closed conveyor route in Fig. There are 6 further points where the direction of the conveying path changes. Firstly, at point PV2, the conveyed material is initially moved upwards by means of the deflection devices 13e, 13f, 13g, 13h, resulting in a vertical change of direction. Subsequently, after point PV1, there is a straight section of the conveying path at the end of which another vertical change of direction occurs, in this case conveying the material downwards, before it is then conveyed again in a straight direction along another straight section of the conveying path.

[0057] At another point, the belt 10 is diverted around a receiving space 16 by means of the deflection device 13i.

[0058] The Fig. The configuration shown in Figure 6 can be expanded or simplified in any way by adding further deflection devices or omitting individual deflection devices. In any case, a closed conveying path with only a single closed belt is advantageously created. Due to the closed shape of the belt, no return of the belt (without transporting goods) is necessary, thus advantageously eliminating an empty lane. The cycle formed by the closed shape of the belt 10 results in a closed conveying path, allowing the conveyed goods 10 to be transported along a closed track. Therefore, there is no empty lane, but only a loaded lane, since no return of the belt 10 from an end point of the conveying path to an beginning of the conveying path is required.

[0059] Fig. Figure 7 shows a detailed view of the receiving chamber 16, in which a schematically indicated functional module 17 is arranged. The conveyor belt 10 is guided around the functional module 17 by means of the deflection device 13i. The conveying path runs through the functional module 17, so that the conveyed material is moved from the first conveying path section 11 through the functional module 17 to the second conveyor belt section 12.

[0060] The deflection device 13i from Fig. Figure 6 comprises several deflection pulleys 14a, 14b, 15a, 15b, which are not shown for clarity, but whose positions P1, P2, P3, P4 are shown. All deflection pulleys 14a, 14b, 15a, 15b are arranged parallel to each other. The first and second deflection pulleys 14a, 14b are arranged in the same horizontal first plane. The third and fourth deflection pulleys 15a, 15b are arranged in the same horizontal second plane, which is different from the first plane.

[0061] Fig. Figure 8 shows a section of a belt conveyor device 100 with a belt 10 and a drive roller 15c, which can be driven by means of a drive device (not shown) to move the belt 10. It can be seen that there is no return of the belt 10, so that the belt conveyor device 100 advantageously has no slack.

[0062] Fig. Figure 9 shows a detailed view of a drive unit 19 for driving a deflection pulley in the area of ​​a horizontal change of direction between the first and the second conveyor section 11, 12. It can be seen in particular that only one drive unit 19 must be provided in this area, since a continuous belt 10 is guided through both the first and the second conveyor section 11, 12.

[0063] In Fig. Figure 10 shows a detailed view of the drive unit 19. The conveyor belt 10 is guided section by section from the conveyor path to the deflection roller 15a, which is connected to the drive unit 19, by means of two deflection rollers (not shown). The rotation of the deflection roller 15a drives or moves the conveyor belt 10, which is engaged with the deflection roller 15a.

[0064] Fig. Figure 11 shows a belt conveyor device comprising a direction adjustment device 21 for adjusting an angle in a horizontal plane between the first conveying path section 11 and the second conveying path section 12.
