[0022] figure 1 A perspective view of the conveying device 10 according to the invention is shown. The conveying device 10 includes a first conveying section 11 and a second conveying section 12, and the second conveying section diverges perpendicularly from the first conveying section 11. The first conveying section 11 includes four parallel conveying belts 31, and the second conveying section 12 includes three parallel conveying belts 31. The conveyor belts 31 are respectively constructed in the form of conveyor modules 30 according to DE 20 2008 011 613 U1. All the contents of DE 20 2008 011 613 U1 are involved and become the contents of this application.
[0023] All conveying modules 30 are constructed essentially the same, wherein the conveying modules 30 of the first and second conveying sections 11; 12 differ only in their length. Each conveying module 30 includes a supporting profile 32, which is made of aluminum by extrusion. The continuous conveyor belt 31 is guided on the outside around the support profile 32, wherein the conveyor belt lies on a flat support surface on the top and the conveyor belt is received below in a covered groove of the support profile 32. At the ends of the supporting profile, an end head 33 is respectively provided, which has a rotatable turning roller for the conveyor belt 31. The steering roller can choose whether to be driven by a motor. The parallel conveying modules 30 of the conveying sections 11; 12 are fixedly connected to each other by connecting profiles 34, so that all conveying belts 31 define a common conveying surface.
[0024] In the intersection area 13 between the first and second conveying sections 11; 12, a conversion device 40 is provided, by means of which objects (not shown) can be conveyed, especially glass sheets, from the first conveying section 11 switches to the second conveying section 12 and vice versa. The conversion device 40 is equipped with a total of six parallel conveying rollers 60 for this purpose, and the conveying rollers can be raised and lowered by the lifting frame 41. When the rectangular glass plate moves along the first conveying section 11, the conveying roller 60 is located below the conveying surface. Once the proximity switch 16 recognizes on the first conveying section that the glass sheet is located in the intersection area 13, the first conveying section 11 stops operating. The correct position of the glass plate can be additionally ensured by means of multiple separators (Vereinzeler) 14. The separator has a movable locking element 15 which can choose whether to move on the stroke of the glass sheet. In the first case, the separator 14 stroke is used to stop the glass sheet. Once the glass sheet stops running in the intersection area 13, the lifting frame 41 is raised by means of four lifting drives 46, so that the conveying roller 60 and the glass sheet form a follow-up engagement (Mitnahmeeing riff). If the conveying roller 60 is in a rotational movement, the glass sheet moves transversely to the first conveying section 11 to the second conveying section 12. The conveyor belt 31 of the second conveyor section 12 is in motion here, so that the conveyor belt can continue to transport the glass sheets. Once the glass plate is out of engagement with the conveying roller 60, the lifting frame 41 and the conveying roller 60 descend again. The whole process can also be carried out in the opposite direction, so that the glass sheet can be transferred from the second conveying section 12 to the first conveying section 11. Here, the rotatable roller 17 serves as a stop for the movement of the glass plate.
[0025] The conveying roller 60 has an O-ring 66 made of rubber on its circumferential surface, and a glass plate is placed on the O-ring. Here, two O-rings 66 are each mounted on a locking ring 67, which is composed of two identical half-shells. The locking ring 67 can be moved to each arbitrary position of the cylindrical base 62 of the conveying roller 60 and clamped therewith.
[0026] in figure 1 It can also be seen that the conveyor belt 31 of the first conveying section 11 traverses the lifting frame 41 so that the conveying module 30 will not be interrupted in the intersection area 13. In addition, it can be seen that two conveying rollers 60 are respectively arranged between two adjacent conveying belts 31 or conveying modules 30 of the first conveying section 11. It can also be seen that the rectangular lifting frame 41 extends substantially over the entire width of the first and second conveying sections 11; With regard to the second conveying section, its width is even slightly larger. What is important for the size of the lifting frame is that the conveying roller 60 supports the glass sheet substantially through its entire supporting surface, and it is sufficient that a plurality of supporting points are distributed on the supporting surface.
[0027] figure 2 An exploded view of the conversion device 40 is shown. The conversion device 40 includes a lifting frame and a fixed frame 41; 44, which respectively have the same external dimensions, wherein they overlap each other closely at the deepest position of the conversion unit 40. The lifting frame and the fixing frame 41; 44 are respectively composed of four straight and longitudinally extending lifting brackets and the fixing brackets 42; 45, which are made of aluminum by extrusion. In the corner regions of the rectangular lifting frame 41 are respectively provided lifting driving devices 46, wherein all lifting driving devices 46 are formed identically. Each lifting driving device 46 includes lifting parts and fixing parts 47; 48. The lifting member 47 connects the four lifting brackets 42 of the lifting frame 41 into a rectangle, and the fixing member 48 connects the four fixing brackets 45 of the fixing frame 44 into a rectangle. The lifting part and the fixing part 47; 48 are connected to each other by a pneumatic lifting device. The fixing part 48 constitutes a cylinder chamber of the pneumatic cylinder, a piston rod extends from the cylinder chamber, and the piston rod is fixedly connected with the lifting part 47. In addition, a sliding guide is provided between the lifting part and the fixed part 47; 48, so the lifting frame and the fixed frame 41; 44 can only move relative to each other perpendicular to the conveying surface.
[0028] The conveyor roller 60 is connected to the lifting frame at its two ends by L-shaped holders 65, wherein the holders 65 are screwed to the associated lifting bracket 42 at any arbitrary position. The holder 65 carries a rotating bearing 64, which is preferably designed in the form of a rolling bearing. The base 62 of the conveying roller 60 is rotatably held by a rotating bearing 64. Every two adjacent conveying rollers 60 are connected by a first traction device 80, that is, a multi-groove V-belt rotationally driving, wherein the first traction device 80 is joined to the end of the conveying roller 60. One of the two conveying rollers 60 is rotationally and drivingly connected to the intermediate shaft through the second traction device 81, this reference image 3 with Figure 4 Will also elaborate. The first and second traction devices 80; 81 are joined directly adjacent to each other into a common conveying roller 60.
[0029] A motor 87 in the form of a drive motor is threadedly connected to the intermediate bracket 88, which is in turn threadedly connected to two opposite lifting brackets 42. The middle bracket 88 is also made of aluminum by extrusion, and extends parallel to the other two lifting brackets 42. It is also necessary to specify different cover plates 89 by which most of the movable parts of the drive device are covered, so as to protect them from the surrounding environment.
[0030] image 3 A cross-sectional view of the conversion device 40 is shown, where the cross-section is perpendicular to the conveying roller 60 so that the first and second traction devices 80; 81 can be seen. Figure 4 The cut position is basically the same as image 3 The cut-away positions of the two are the same, but the viewing direction is opposite, so the third traction device 82 can be seen. A total of three intermediate shafts 84; 85; 86 are provided, which are located just below the associated conveying roller 60. The intermediate shafts 84; 85; 86 are rotatably supported, with their rotation axis extending parallel to the conveying roller 60. Each intermediate shaft 84; 85; 86 is connected by a second traction device 81, that is, a multi-groove V-belt, and an associated conveying roller 60 in rotation and driving, wherein the conveying roller 60 is connected to the adjacent conveying roller 60 through the first traction device 80 The conveying roller 60 is connected for rotational drive. The first intermediate shaft 85 is directly driven by a motor 87 in the form of a drive motor. The drive shaft of the drive motor 87 is connected to the first intermediate shaft 84 in a non-rotatable manner through a coupling. The first intermediate shaft 84 is rotationally drivingly connected with the second intermediate shaft 85 through the third traction device 82. The second intermediate shaft 85 is rotationally drivingly connected with the third intermediate shaft 86 by means of another third traction device 82. The third traction device 82 is designed in the form of a toothed belt. Each third traction device 82 is equipped with a rotatable and position-adjustable tension roller 83, by means of which the stress of the associated third traction device 82 can be adjusted. On the contrary, the stress of the first and second traction devices 80; 81 is adjusted by the distance between the conveying roller 60 and the intermediate shaft 84; 85; 86, and their positions can be adjusted steplessly.
[0031] Figure 5 A partial cross-sectional view of the conversion device 40 is shown, wherein the cross-section extends through the first intermediate shaft 84 perpendicular to the conveying surface. The constant cross-sectional shape of the lifting bracket 42 can be seen, which has a rack bar section 43 perpendicular to the conveying surface. The pinion shaft 49 includes a hexagonal shaft 50, which is rotatably supported on a fixed member of the lifting drive device. On the hexagonal shaft 50, a plurality of pinion gears 51 are dispersedly arranged over the entire length, wherein the external tooth portion 52 of the pinion gear 51 is meshed with the rack bar section 43. Since the pinion gear 51 is form-fittingly meshed into the hexagonal cross-sectional shape of the hexagonal shaft, it is ensured that all the pinion gears 51 rotate synchronously. As a result, it is achieved that the lifting bracket 42 always extends parallel to the pinion shaft 49, which is again configured parallel to the conveying surface of the conveying device.
[0032] The first and second traction means 80; 81 are engaged in a common pulley 63 which is integrally formed on the base 62 of the conveying roller. In addition, in Figure 5 There can also be seen a rotating bearing 64 which is preferably designed as a rolling bearing and which is fixed on an L-shaped holder 65, wherein the rotating bearing carries the base 62 of the transport roller 60. The holding member 65 is in turn fixed on the lifting bracket 42 by a T-head screw 90, where the T-head screw engages in the undercut T-shaped groove.
[0033] Note also the O-ring 66 already mentioned, which is carried by the locking ring 67, which is locked with the base 62 of the conveyor roller. Also in Figure 5 The constant cross-sectional shape of the fixing bracket 45 can be seen in this.
