Definitions

• the invention relates to an inspection system for rolled products of a rolling mill.
• the surface of the rolled products is usually inspected by a test person after a rolling process.
• a technique can be used in which the surface of a rolled product is ground, for example using a stone, in order to make irregularities in the surface structure visible through this process.
• the texture of the substrate is imprinted on the underside of the rolled product or even pressed through the rolled product and thus becomes recognizable on the upper side.
• errors that have arisen during the rolling process may not be recognized correctly and therefore cannot be assigned to the correct source of error.
• the invention is therefore based on the object of specifying an inspection system for rolled products of a rolling installation of the type mentioned above, which reliably prevents the texture of the substrate from being imprinted and / or imprinted when the rolled product is processed, in particular when grinding.
• This object is achieved according to the invention by arranging a number of height-adjustable rolled product clamps on a conveyor belt for rolled products in the inspection system.
• the invention is based on the consideration that when processing the rolled product, in particular when grinding, by exerting pressure on its surface, it is almost inevitable that the texture of the substrate be imprinted or imprinted on the rolled product to be tested.
• the inspection system should be designed in such a way that the rolled product to be inspected is decoupled from its substrate during grinding , This can be achieved by means of a device which allows the rolled product to be lifted off the ground.
• a number of height-adjustable rolled product clamps are arranged on a conveyor belt for rolled products in the inspection system.
• these rolled product clamps it is possible to fix the rolled product in question and to bring it securely into a position raised by the conveyor belt for the grinding process and to maintain this position during processing.
• the rolled product is expediently in the tensioned state.
• a height-adjustable clamping station is advantageously provided between two rolled product clamps.
• Figure 1 a-f is a schematic side view of an inspection system in different positions of the rolled product clamps and / or the clamping station for rolled products.
• the inspection system 1 for rolled products 2 of a rolling system serves to check the surfaces of a rolled product 2, for example of metal sheets, for defects which may have arisen during the rolling process.
• the rolled product 2 is usually on a surface, such as on a conveyor belt 4.
• grinding or another type of pressure is exerted on the surface of the rolled product 2 resting on the conveyor belt 4
• an impression and / or print of its texture can be imaged on the rolled product 2 by direct contact with the conveyor belt 4, which can at least interfere with errors regarding the rolling process during the inspection.
• the inspection system 1 in the exemplary embodiment according to FIGS. 1a to 1f comprises two height-adjustable rolled product clamps 6, 8 on the conveyor belt 4 in the conveyor belt direction X. These can lift the rolled product 2 from the conveyor belt 4 if necessary, so that the surface of the rolled product 2 during processing has no contact with it, which can lead to impairments for a reliable surface inspection.
• the inspection system 1 also has a clamping station 10 arranged between the two rolled product clamps 6, 8 for improved grinding of the rolled products 2.
• the rolled product clamps 6, 8 and the tensioning station 10 are lowered in their starting position at a height below the conveyor belt 4.
• the rolled product 2 can be conventional are inspected and fed to a device for further processing.
• FIGS. 1 b and 1 c show the rolled product clamps 6, 8 after both have been raised accordingly in an intermediate position elevated from the starting position, which serves as the receiving position for the rolled product 2.
• the rolled product 2 to be ground is inserted into the rolled product clamps 6, 8 and, in the exemplary embodiment, firmly clamped by them in the edge regions 12 of the rolled product, for example by means of so-called clamping jaws 14.
• This firmly clamped state of the rolled product 2 with the mutually rotated clamping jaws 14 is shown in Fig. 1c.
• FIG. 1d shows the inspection position of the rolled product clamps 6, 8 with the rolled product 2 clamped in by means of the clamping jaws 14.
• the rolled product clamps 6, 8 are at an ergonomically favorable height, e.g. Table height, raised.
• the clamping station 10 is also designed to be height-adjustable in order to clamp the rolled product 2 clamped in the rolled product clamps 6, 8 in the elevated inspection position in the exemplary embodiment for a uniform grinding of the upper side of the relevant rolled product 2.
• the clamping station 10 which in the exemplary embodiment has a shape in the manner of a stamp, with a molded part 16, which is visually similar to a stamp pad, presses the rolled product 2 over its underside up to a suitable grinding tension of the rolled product 2.
• the upper side of the rolled product 2 detached and tensioned from the conveyor belt 4 can then be ground for inspection purposes without the surface image of the rolled product 2 being falsified or disturbed by the texture of the conveyor belt 2.
• the clamping station 10 is lowered again to the level of the starting position described for FIG. 1 a. While the two rolled product clamps 6, 8 with the clamped rolled product 2 initially on the Height of the intermediate position described in FIG. 1b.
• the clamping mechanism of the rolled product clamps 6, 8 is then unlocked, so that in the exemplary embodiment their clamping jaws 14 release the inspected rolled product 2.
• the clamping jaws 14 are therefore no longer shown rotated relative to one another in FIG. 1e, but parallel to one another.
• the rolled product 2 is then moved in the exemplary embodiment in the direction of conveyance X out of the rolled product clamp 6 initially located in the conveying direction X, and the thus rolled product clamp 6 is lowered again into the starting position.
• FIG. 1e thus shows the tensioning station 10 and the rolled product clamp 6 below the conveyor belt 4. Then, in the exemplary embodiment, the rolled product 2 is moved against the conveying direction X until the rolled product clamp 8 following in the conveying direction X is also free and the now free rolled product clamp 8 lowered into the starting position.
• the illustration in FIG. 1f accordingly shows the tensioning station 10 and the rolled product clamps 6 and 8 again below the conveyor belt 4.
• the rolled product 2 is again shifted in the conveying direction X until it returns to its starting position, as shown in FIG. 1 a.
• the rolled product 2 can also first be moved out of the rolled product clamp 8 and then be lowered into the starting position in front of the rolled product clamp 6.
• the signs of the conveying direction X of the rolled product 2 must be changed accordingly.
