Abstract
Description
Technical Field
[0001] The invention relates to a transverse conveyor for a roller conveyor for conveying heavy loads, such as slabs or blocks, plates, sheets or coils made of metal material or containers and other heavy individual goods. Background Art
[0002] Roller conveyors for transporting heavy loads such as slabs, blocks, plates, sheets or coils made of metallic material as well as containers or the like are sufficiently known from the prior art.
[0003] For example, in casting and rolling plants (in which slabs are cast in at least one casting machine and in a subsequent step are produced in a rolling mechanism for reforming into thin strips or plates (which are finally coiled into coils)), roller tables are commonly used devices for conveying and transporting cast strands, each intermediate product, and finished rolled thin strips or plates. Such slabs or blocks usually have a weight of more than 30 tons, especially more than 35 tons, which places high demands on the load-bearing capacity, heat resistance and reliability of the roller tables.
[0004] In order to remove slabs, blocks, plates, sheets, coils, containers or the like from a conveyor roller conveyor or, if necessary, to supply further slabs or blocks, plates, sheets, coils or containers to the conveyor roller conveyor, transverse conveyors are known from the prior art, which can convey a conveyor roller conveyor section laterally transversely to the extension direction of the roller conveyor and are preferably oriented in alignment with a second conveyor roller conveyor extending likewise horizontally, in order to then continue to transport the slabs or blocks, plates, sheets, coils or containers and the like further.
[0005] In casting and rolling plants, especially in such casting and rolling plants of the CSP concept, this necessity is even more present, because the production capacity of the casting plant is significantly different from the production capacity of the downstream rolling mill. Therefore, slabs or blocks are usually fed laterally from a warehouse to a conveyor roller table in front of the rolling mill, or a rolling mill is fed simultaneously from two parallel casting plants. A transverse conveyor is then used to receive the slabs or blocks from the conveyor roller table downstream of the respective casting machine and to feed them to the conveyor roller table upstream of the rolling mill.
[0006] Due to the high loads that must be reliably carried and moved by the conveyor rollers and therefore also by the transverse conveyors, a great deal of work has hitherto been required in order to ensure that the transverse transport can be carried out horizontally and without terrain obstacles. Therefore, in practice, a great deal of preparatory work is required in order to ensure horizontal transverse transport of the transverse conveyor, even if the topography of the plant or the plant layout does not actually provide for this. If the conveyor rollers are inevitably at different height levels and therefore in different horizontal planes, a lifting mechanism must be provided in order to overcome the height difference. The transverse conveyor is then usually transported horizontally from the first conveyor roller to the lifting mechanism by means of the transverse conveyor and then transported vertically by the lifting mechanism to the second conveyor roller or, if necessary, to a further transverse conveyor for further horizontal movement.
[0007] The preparatory measures required for this are therefore considerable and the cycle times achievable with this combination of transverse conveyor and lifting table are unsatisfactory. Summary of the invention
[0008] The object of the present invention is therefore to provide a transverse conveyor which can also be used if, due to the topography of the plant or for reasons specific to the layout of the plant, it is not possible to transport only horizontally from a first conveyor roller conveyor to a second conveyor roller conveyor. According to the invention, this object is achieved with a transverse conveyor comprising the features of claim 1. Advantageous embodiments of the invention are set forth in particular in the dependent claims.
[0009] According to the invention, a transverse conveyor is provided for conveying heavy loads from a first horizontally extending conveyor roller conveyor to a second horizontally extending conveyor roller conveyor, wherein the transverse conveyor is designed as a roller conveyor section and is arranged and configured to be inserted into the first conveyor roller conveyor and the second conveyor roller conveyor in an aligned manner, and the transverse conveyor comprises a device for conveying the transverse conveyor transversely between the conveyor roller conveyors. According to the invention, the device for conveying the transverse conveyor transversely is arranged and configured to overcome the height difference between the first conveyor roller conveyor and the second conveyor roller conveyor.
[0010] Thus, a transverse conveyor is provided which can bridge two conveyor roller conveyors regardless of the terrain or the plant layout, thereby conveying heavy loads from the first conveyor roller conveyor to the second conveyor roller conveyor and back again when height differences must be overcome. According to the invention, a single device is provided in order to effect both the transverse conveyance and the overcoming of height differences.
[0011] According to the invention, major preparatory work is thus omitted and the throughput of the transverse conveyor is significantly increased compared to prior art devices that cause horizontal transverse transport as well as vertical transport by means of lifting tables or the like. Furthermore, the transverse conveyor according to the invention can be integrated into the first and second conveyor roller conveyors, so that it is possible to easily remove heavy loads from the first conveyor roller conveyor, to transport them transversely by means of the transverse conveyor, and to transport them further to the second conveyor roller conveyor.
[0012] According to the invention, it is particularly preferred that the device for the transverse transport is designed and set up to carry out the transverse transport and the overcoming of the height difference in one movement, preferably in a single, uninterrupted movement extending in a single direction. As a result, the transverse conveyor according to the invention is particularly simple to realize and the travel path of the transverse conveyor and the heavy loads placed on it are also limited to a minimum.
[0013] According to the invention, it is further preferred that the height difference between the first conveyor roller conveyor and the second conveyor roller conveyor results in a preferably constant slope for the travel path of the transverse conveyor. A slope of at least 1°, preferably at least 4°, particularly preferably 4° to 10°, extremely preferably more than 10°, in particular 10° to 45° is preferred. This provides a transverse conveyor that can be optimally adapted to different terrains or height differences and that can also reliably and without problems overcome greater height differences.
[0014] Particularly preferably, the device for transverse transport is operatively connected to at least one rail, preferably two rails, for guiding the transverse conveyor. This creates a possibility for transverse transport, in which the transverse conveyor can be transported reliably and in a targeted manner between the first conveyor roller conveyor and the second conveyor roller conveyor, without incorrect orientation or deviations occurring during the transverse transport. In particular, the transverse conveyor can be aligned with the first conveyor roller conveyor and the second conveyor roller conveyor in a targeted and targeted manner.
[0015] In another preferred embodiment of the invention, the device for transverse transport has at least one driven wheel for transporting the transverse conveyor on at least one, preferably two, tracks. The slope of the travel path is preferably about 1° to 4°. According to the invention, a transverse conveyor is provided which can achieve a slight slope by simple and manageable means in the case of large spacings between the conveyor rollers to be bridged by the transverse conveyor or in the case of only small height differences between two conveyor rollers. Due to the Hertzian pressure between the wheel and the track, slopes of 1° to 4° can be reliably achieved solely on the basis of the force fit between the transverse conveyor and the track.
[0016] In an alternative and equally preferred embodiment of the invention, the device for transverse transport has at least one driven pinion for transporting the transverse conveyor on at least one rack or at least one pin rack. The slope of the travel path is preferably 4° to 10°. This provides a transverse conveyor that can be used when rail transport is no longer possible or is only possible to a limited extent due to the slope. Preferably, the pinion, preferably a driven pinion, meshes in a rack arranged parallel to the track or in a so-called pin rack, in which no sequence of teeth is provided, but rather a plurality of columns arranged at defined distances from one another enable the engagement of the pinion meshing with the pin rack.
[0017] In another alternative and likewise preferred embodiment of the invention, the device for transverse transport comprises at least one lifting mechanism, which comprises at least one cable for transporting the transverse conveyor, preferably a cable running on at least one cable drum. In this case, the slope of the travel path is preferably greater than 10°. A transverse conveyor is provided, which can also reliably overcome greater slopes and provides a simple and easily manageable means for overcoming height differences and for simultaneous transverse transport. In particular, when the cable assembly has a large number of cable drums or reversing pulleys, then the force expended for transverse transport is significantly reduced according to the principle of the pulley assembly.
[0018] In another preferred embodiment of the invention, the device for transverse transport is constructed and set up so that at least two transverse conveyors move, preferably simultaneously, between at least two conveyor rollers. It is particularly preferred that a third conveyor roller extending horizontally is arranged between the two conveyor rollers, wherein the third conveyor roller has a height difference, preferably the same height difference, with the first and second conveyor rollers, wherein the device for transverse transport is designed and set up so that the first transverse conveyor is transported from the first conveyor roller to the third conveyor roller and simultaneously the second transverse conveyor is transported from the third conveyor roller to the second conveyor roller. Thus, a transverse conveyor is provided that can provide a particularly high number of cycles when feeding the third conveyor roller from the first and second conveyor rollers. In particular, when the third conveyor roller is arranged higher than the first and second conveyor rollers, the energy expended when transporting the heavy load from the second conveyor roller to the third conveyor roller by means of the first transverse conveyor is at least partially compensated by the second transverse conveyor being simultaneously moved from its position in front of the third conveyor roller back to its end position behind the second conveyor roller. When the first transverse conveyor thus follows the height difference of the slope upwards, the second transverse conveyor simultaneously or preferably moves downwards on the same height difference and optionally follows the same slope downwards. Thus, the energy obtained when the second transverse conveyor moves can be used to transport the first transverse conveyor.
[0019] Furthermore, it is preferred that means for energy recovery are provided in order to store the energy released during the transverse transport and to use it when required.
[0020] According to the invention, preferably, the conveyor rollers extend parallel to each other. In the sense of the invention, such conveyor rollers are considered parallel, which do not cross each other, wherein deviations from the exact parallelism of + / -10° do not interfere with the operation of the transverse conveyor according to the invention.
[0021] In a preferred embodiment of the invention, the conveyor roller table is a component of the casting and rolling plant, wherein the first and second conveyor roller tables and the transverse conveyor connect the two casting machines to the rolling unit.
[0022] According to the invention, the heavy load is a slab, block, plate, sheet or coil made of metal material, as is generally known in the steel industry or the aluminum industry as a raw material and processed product. The conveyor rollers and transverse conveyors according to the invention are in principle capable of reliably transporting all reactants and products and intermediate products even at high temperatures and high weights, for example more than 5 tons, preferably more than 10 tons, particularly preferably more than 15 tons. Likewise, the invention can also be applied to the transport of containers and / or piece goods weighing at least 5 tons or more. BRIEF DESCRIPTION OF THE DRAWINGS
[0023] The invention is explained in more detail below with reference to two drawings, from which preferred embodiments of the invention emerge. The drawings are not intended to limit the scope of protection of the invention.
[0024] in:
[0025] Figure 1 A schematic diagram of two transverse conveyors according to the invention is shown, which connect the first conveyor roller conveyor and the second conveyor roller conveyor to the third conveyor roller conveyor, respectively, and
[0026] Figure 2 An enlarged detail of a driven pinion which meshes in a pin rack to drive the transverse conveyor is shown. DETAILED DESCRIPTION
[0027] Figure 1Two transverse conveyors 1a, 1b according to the invention are shown, wherein the first transverse conveyor 1a connects the first conveyor roller conveyor 2 with the third conveyor roller conveyor 12 and the second transverse conveyor 1b connects the second conveyor roller conveyor 3 with the third conveyor roller conveyor 12. The third conveyor roller conveyor 12 is arranged higher than the first and second conveyor roller conveyors 2, 3, so that when conveying the thin slabs 5 to the third conveyor roller conveyor 12, the transverse conveyors 1a, 1b have to cope with a slope of more than 10°. The transverse conveyors 1a, 1b are designed as roller conveyor sections which can be aligned behind the first and second conveyor roller conveyors 2, 3 and in front of the third conveyor roller conveyor 12, so that the thin slabs 5 can be conveyed without problems not only from the first and second conveyor roller conveyors 2, 3 to the transverse conveyors 1a, 1b but also from the transverse conveyors 1a, 1b to the third conveyor roller conveyor 12. The transverse conveyors 1a, 1b run on rails 6 between the conveyor rollers 2, 3, 12 in order to ensure a secure transport of the thin sheet metal sheets 5 on the transverse conveyors 1a, 1b and an aligned orientation of the transverse conveyors 1a, 1b to the conveyor rollers 2, 3, 12. Cables 11 are used for the transverse transport of the transverse conveyors 1a, 1b and are connected to a motor 13 and the respective transverse conveyor 1a, 1b. The cables 11 extend around cable drums or diverting pulleys 10 so that the forces currently applied for the transverse transport of the thin sheet metal sheets 5 can be kept low. In the arrangement shown here of transverse conveyors 1a, 1b and three conveyor rollers 2, 3, 12, the thin plate 5 is transported from the first conveyor roller 2 upward along the gradient to the third conveyor roller 12 by means of the first transverse conveyor 1a, while preferably at the same time the second transverse conveyor 1b starts from the third conveyor roller 12 and travels downward along the gradient of the travel path to its position behind the second conveyor roller 3 in order to receive a new heavy load, for example in the form of another thin plate 5, from there.
[0028] Figure 2 A detailed view of a conveying drive for a transverse conveyor according to the invention (not shown) is shown, which comprises a pinion 8 connected to a drive (not shown) and meshing in a pinion rack 9 in order to reciprocate the transverse conveyor (not shown) along the pinion rack 9. The pinion rack consists of a plurality of columns 14, which are arranged at predefined distances on a rail or the like, wherein the teeth of the pinion 8 sink into the distances between the columns 14 and thus cause the transverse conveyor (not shown) to be advanced.
