Description

[0001] Method and machine arrangement for the separating processing of plate-like workpieces

[0002] The invention relates to a method for monitoring the quality of a processing product produced from a plate-like starting workpiece, in particular a sheet metal, during an ongoing manufacturing process, wherein an actual state of at least one parameter of the quality of the processing product is recorded during the manufacturing process.

[0003] The invention further relates to a method for controlling an ongoing manufacturing process and to a manufacturing process, wherein, within the scope of this method, the quality of a machining product produced by separating a starting workpiece is monitored according to the aforementioned monitoring method.

[0004] The invention also relates to a mechanical arrangement for the separating processing of plate-like workpieces, in particular of sheet metal, • with a separating device by means of which a processing product can be produced from an initial workpiece by separating the initial workpiece and

[0005] • with a monitoring device which is designed to detect the condition of the processing product, in that the monitoring device has a detection device by means of which an actual state of at least one parameter of the condition of the processing product can be detected on the processing product.

[0006] Finally, the invention relates to a computer program for operating a mechanical arrangement of the aforementioned type.

[0007] The prior art in this field is disclosed in DE 10 2020 123 555 A1.

[0008] The prior art relates to a method and a device for automated quality control on cutting systems for the separating processing of fabric material strips. Fabric material pieces are produced on a processing unit of the known device by separating a fabric material strip. After their production, the fabric material pieces are moved along a camera, which records the quality of the fabric material pieces. A control unit of the device checks whether the recorded quality of the fabric material pieces corresponds to the relevant specifications. If defective fabric material pieces are identified, the control unit modifies selected parameters of the processing unit in order to eliminate the cause of the error and enable the subsequent production of defect-free fabric material pieces.

[0009] The object of the present invention is to avoid as far as possible the production of defective machining products during the separating machining of workpieces, in particular sheet metal.

[0010] According to the invention, this object is achieved by the monitoring method according to claim 1, by the control method according to claim 5, by the manufacturing method according to claim 8, by the mechanical arrangement according to claim 9 and by the computer program according to claim 18. In the case of the invention, the quality of a processing product produced by separating a starting workpiece is recorded in advance of the production of the processing product based on that area of ​​the starting workpiece which forms the processing product after separating processing. The actual state of at least one parameter of the quality of the starting workpiece is recorded location-specifically on the starting workpiece. It is thus known in which area of ​​the starting workpiece the parameter of the quality of the starting workpiece has which actual state.For the detection of the actual state of a parameter of the quality of the initial workpiece prior to the separating processing, the mechanical arrangement according to the invention has a detection device arranged upstream of the separating device.

[0011] At the same time, it is already known in advance of the separating machining of the starting workpiece, for example, due to a nesting of the starting workpiece with machining products stored for the starting workpiece in a numerical control system of the inventive machine arrangement, which area of ​​the starting workpiece will form the machining product after its separating machining. The actual state of the parameter of the quality of the starting workpiece identified for this area is assigned to the product-forming area of ​​the starting workpiece by means of an evaluation device as the actual state of the quality of the machining product.

[0012] The monitoring concept according to the invention makes it possible to gain knowledge about the quality of the processed products produced at an early stage of an ongoing production process and, if necessary, to intervene in the production process in a controlling manner.

[0013] The computer program according to the invention controls the inventive mechanical arrangement for carrying out the inventive manufacturing method and, for this purpose, includes corresponding control commands for a numerical arrangement control. Particular embodiments of the invention according to independent patent claims 1, 5, 8, 9, and 18 are set forth in dependent patent claims 2 to 4, 6, 7, and 10 to 17.

[0014] In a preferred embodiment of the method according to the invention, an actual state of at least one parameter of the quality of the processed product is recorded even after the separating processing of the starting workpiece. The recording takes place on the processed product (patent claim 2). A mechanical arrangement provided for implementing this embodiment of the method according to the invention has a monitoring device with a recording device arranged downstream of the separating device (patent claim 10).

[0015] In a further embodiment of the method according to the invention, the actual state of at least one parameter of the quality of the processed product that remains unchanged during the further manufacturing process is recorded on the starting workpiece and / or on the processed product (patent claim 3). A one-time recording of the actual state of the quality parameter(s) is sufficient in this case. The actual state of the quality parameter of the starting workpiece recorded on the starting workpiece readily reflects the actual state of the quality of the processed product.

[0016] In a further embodiment of the invention, the thickness and / or the surface quality and / or the flatness and / or the cutting edge quality and / or the dimensional accuracy of the machining product are monitored as quality parameters that are particularly relevant for the quality of a machining product produced by separating a starting workpiece (patent claims 4, 11).

[0017] To control the mechanical arrangement according to the invention, in a further embodiment of the invention, the actual state of the parameter in question, the quality of the processed product, recorded before and / or after the separating machining of the starting workpiece, is compared with an associated target state. The manufacturing method according to the invention and / or the mechanical arrangement according to the invention are controlled depending on the comparison result (claim 6).

[0018] In a further preferred embodiment, the mechanical arrangement according to the invention has a numerical arrangement control according to patent claim 12 or patent claim 13.

[0019] When controlling the mechanical arrangement according to the invention, the framework conditions of the monitored ongoing production process can also be taken into account (patent claims 7, 14).

[0020] Information about the general conditions of the ongoing manufacturing process is optionally stored in a preferably programmable data memory of the numerical control system of the inventive machine arrangement. For example, it is conceivable that, even before the separating machining of the initial workpiece, it is determined within the scope of the inventive monitoring of the condition of the product-forming area of ​​the initial workpiece that, due to the determined condition of the initial workpiece, the ongoing process cannot produce the processed products with the desired quality.If, at the same time, information stored in the data memory of the numerical arrangement control shows that the condition of the starting workpiece, which is unsuitable for the current process, meets the quality requirements of a manufacturing process that is planned after the current manufacturing process, the current manufacturing process can be aborted by means of the numerical arrangement control and the subsequently planned manufacturing process can be brought forward.

[0021] In a further preferred embodiment of the invention, the data storage for the framework conditions of the ongoing production process is part of an ERP (Enterprise Resource Planning) system (patent claim 15). Functional units of the mechanical arrangement according to the invention, which are controlled as a function of the quality of the processed product monitored before and / or after the separating processing of the starting workpiece, are, in particular, the separating device of the mechanical arrangement and / or a loading device arranged on a supply side of the separating device, by means of which the starting workpiece can be fed to the separating device, and / or an unloading device arranged on a discharge side of the separating device, by means of which the processed product can be discharged from the separating device (patent claim 16).

[0022] A particularly practical application of the present invention is the separating sheet metal processing from coils (patent claim 17). In separating sheet metal processing from coils, the output of processed products is extremely high. Against this background, it is particularly important to determine the quality of the produced processed products as early as possible and, if necessary, to influence an ongoing production process as early as possible.

[0023] The invention is explained in more detail below using exemplary schematic representations.

[0024] They show:

[0025] Figure 1 shows a machine arrangement for the separating sheet metal processing from the coil and

[0026] Figure 2 shows a machine arrangement for the separating processing of sheet metal panels.

[0027] According to Figure 1, a mechanical arrangement 1 is used to process a sheet metal 2 wound in the form of a coil 3 onto a reel 4. A straightening device 5 of conventional design with straightening rollers 6 is arranged adjacent to the reel 4.

[0028] The straightening rollers 6 are provided in the usual way with a controllable motor drive and are part of a feeding device 7, by means of which the sheet 2 is unwound in sections from the coil 3 and moved in a feed direction 8 into a working space 9 of a laser cutting machine 10 provided as a separating device.

[0029] The highly schematically illustrated laser cutting machine 10 in the example shown is a conventional flatbed laser machine. The sheet metal 2 is fed section by section to a workpiece support of the laser cutting machine by means of the feeding device 7 as the starting workpiece to be separated. During the separating process, a laser cutting head (not shown) of the laser cutting machine 10 is moved in a known manner with a two-axis horizontal working movement over the section of the sheet metal 2 resting on the workpiece support of the laser cutting machine 10.

[0030] In the present case, a sheet metal workpiece 11 and also a residual skeleton 12 enclosing the sheet metal workpiece 11 are produced from the sheet metal 2 as a processing product.

[0031] After the separating processing is completed, the sheet metal 2 is moved further in the feed direction 8. As a result, the processed section of the sheet metal 2 is transferred to an unloading table 13 arranged downstream of the laser cutting machine 10 in the feed direction 8. At the same time, a still unprocessed section of the sheet metal 2 is moved as a new starting workpiece into its processing position on the workpiece support of the laser cutting machine 10.

[0032] At the unloading table 13, the sheet metal workpiece 11 is picked up by a conventional suction frame 14 serving as an unloading device and is transported by means of the suction frame 14 to a storage location 15, where a first workpiece storage location 16 and a second workpiece storage location 17 are provided. The residual skeleton 12 initially remaining on the unloading table 13 is divided by a device not shown and then also removed from the unloading table 13. Just like the loading device 7 and the laser cutting machine 10, the suction frame 14 also forms a functional unit of the mechanical arrangement 1.

[0033] The quality of the sheet metal workpieces 11 produced on the machine assembly 1 is continuously monitored during the ongoing cutting and manufacturing process. For this purpose, a monitoring device 18 is provided with a first detection device 19, a second detection device 20, and a third detection device 21.

[0034] A sheet thickness gauge 19a is arranged between the reel 4 and the straightening device 5 as a detector for the first detection device 19. The second detection device 20 has a camera 20a as a detector between the straightening device 5 and the laser cutting machine 10. Another camera 21a is provided near the unloading table 13 as a detector for the third detection device 21.

[0035] The first detection device 19, the second detection device 20, and the third detection device 21 have a common numerical detection unit 22. Both the sheet thickness gauge 19a and the camera 20a and 21a are connected to this unit. The numerical detection unit 22 is part of a numerical control system 23 of the machine assembly 1.

[0036] In the example shown, the thickness of the sheet metal 2 unwound from the coil 3 is determined by means of the first detection device 19. In the example shown, the second detection device 20 is used to determine the surface quality of the sheet metal 2 after leaving the straightening device 5, and the third detection device 21 is used to determine the quality of the cutting edges of the sheet metal workpiece 11 transferred to the unloading table 13 after leaving the work area 9 of the laser cutting machine 10. Due to the arrangement of the sheet metal thickness gauge 19a and the cameras 20a, 21a, the first detection device 19 and the second detection device 20 are arranged upstream of the laser cutting machine 10, and the third detection device 21 is arranged downstream of the laser cutting machine 10.The actual states of the thickness and surface quality of the sheet metal 2 recorded by the first recording device 19 and the second recording device 20 as well as the cutting edge quality of the sheet metal workpiece 11 recorded by the third recording device 21 are evaluated in an evaluation unit 24 of the numerical arrangement control 23.

[0037] During an ongoing production process, the sheet metal 2 unwound from the coil 3 is moved intermittently by means of the feeding device 7 in the feed direction 8 over partial feed lengths that are coordinated with the extent of the workpiece support in the feed direction 8 and the range of the laser cutting head in the work space 9 of the laser cutting machine 10. With the aid of a path measuring system of the feeding device 7, the movement of the partial feed lengths of the sheet metal 2 in the feed direction 8 is defined. This ensures that a partial feed length of the sheet metal 2 detected by the sheet thickness measuring device 19a with regard to its thickness and / or a partial feed length of the sheet metal 2 detected by the camera 20a with regard to its surface quality reaches a defined processing position in the work space 9 of the laser cutting machine 10 during its movement in the feed direction 8.At the same time, the allocation of the sheet metal workpiece 11 for a partial feed length of the unprocessed sheet metal 2 is stored in the evaluation unit 24 of the numerical arrangement control 23 of the mechanical arrangement 1. Consequently, the evaluation unit 24 can identify the area of ​​a partial feed length of the unprocessed sheet metal 2 (starting workpiece) on the unprocessed sheet metal 2, which was scanned in sections before the separating processing by means of the sheet metal thickness gauge 19a and the camera 20a. This area, as the product-forming area of ​​the starter workpiece, will form the sheet metal workpiece 11 (processing product) after the separating processing by means of the laser cutting machine 10.

[0038] The evaluation device 24 assigns the actual thickness of the still unprocessed partial length of the sheet metal 2, as recorded by the first recording device 19, as the actual thickness of the sheet metal workpiece 11, and the actual surface quality of the still unprocessed partial length of the sheet metal 2, as recorded by the second recording device 20, as the actual surface quality of the sheet metal workpiece 11. This assignment is readily possible because the actual states recorded by the first recording device 19 and the second recording device 20 remain unchanged throughout the further production process.

[0039] By means of the third detection device 21, the cutting edge condition of the sheet metal workpiece 11 arranged on the unloading table 13 is detected directly on the sheet metal workpiece 11 after the separating sheet metal processing.

[0040] The actual states of the thickness, surface quality, and cutting edge quality of the sheet metal workpiece 11 are compared in the evaluation unit 24 with the target states of these three parameters of the quality of the sheet metal workpiece 11 stored in the evaluation unit 24. Depending on the result of the comparison of the actual state with the target state, the loading device 7, the laser cutting machine 10, and the suction frame 14 are controlled by a control unit 25 of the numerical arrangement control 23 with corresponding control commands.

[0041] If, during the comparison of the actual state with the target state of the monitored parameters of the quality of the sheet metal workpiece 11 carried out in the evaluation unit 24, a deviation of the actual state from the target state is detected, the control unit 25 generates control commands for the relevant functional unit of the mechanical arrangement 1, which bring about an adjustment of the detected actual state to the relevant target state.

[0042] If, for example, the first detection device 19 detects that the thickness of the product-forming region of the unprocessed sheet metal 2 deviates from the thickness of the sheet metal workpiece 11 specified for the ongoing production process, the control unit 25 can shut down the feeding device 7 by issuing a corresponding control command, thereby ensuring that the separating processing of the sheet metal 2 is aborted immediately after the sheet metal feed is initiated, thus preventing the production of inferior-quality sheet metal workpieces 11 from the outset. In the example shown, it is also possible for the numerical arrangement control 23 to take into account the framework conditions of the ongoing production process when controlling the mechanical arrangement 1. Such framework conditions are stored in a programmable data memory 26 of the numerical arrangement control 23.Data storage 26 is part of an ERP (Enterprise Resource Planning) system.

[0043] In the present example, the data memory 26 contains, among other things, information about a manufacturing process that is to be carried out by means of the mechanical arrangement 1 following the ongoing manufacturing process and that differs from the ongoing manufacturing process only in the requirements for the surface quality of the manufactured sheet metal workpieces 11.

[0044] If the evaluation unit 24 determines that the surface quality of the sheet metal workpiece 11 detected by the second detection device 20 does not meet the quality requirements for the current production process, but does meet the quality requirements for the subsequently planned production process, the control unit 25 can abort the current production process and bring forward the production process intended for a later time. Similarly, the numerical arrangement control 23 can control the mechanical arrangement 1 in cases where the thickness of the sheet metal workpiece 11 detected by the first detection device 19 does not meet the current requirements, but does meet the requirements of a subsequently planned production process.

[0045] The information obtained by the third detection device 21 regarding the actual state of the cutting edge quality of the sheet metal workpiece 11 is taken into account by the numerical arrangement control 23 when controlling the suction frame 14. If the third detection device 21 determines that the cutting edge quality of the sheet metal workpiece 11 corresponds to the specifications for the ongoing production process, the control unit 25 controls the suction frame 14 such that the suction frame 14 transfers the sheet metal workpiece 11 to the first workpiece storage area 16 at the storage location 15. If the cutting edge quality of the sheet metal workpiece 11 detected by the third detection device 21 does not meet the specified quality requirements, the control unit 25 controls the suction frame 14 such that the suction frame 14 transports the sheet metal workpiece 11 to the second workpiece storage area 17.The second workpiece storage 17 is intended for sheet metal workpieces 11 whose cutting edges require reworking.

[0046] In the example case shown, the information obtained during the monitoring and control of the mechanical arrangement 1 within the framework of the ongoing production process is transmitted to a data integration platform 27, which can be accessed in future production processes.

[0047] A machine arrangement 100, as shown in Figure 2, differs from the machine arrangement 1 according to Figure 1 in that the sheet metal 2 to be separated is not in the form of a coil, but rather as a sheet metal panel. During processing, the sheet metal panel is stored on a conventional workpiece pallet in the work area 9 of the laser cutting machine.

[0048] The loading device 7 of the mechanical arrangement 100 accordingly does not comprise a straightening device according to Figure 1, but rather a loading device 101 and a pallet changer 102. The loading device 101 and the pallet changer 102 are of conventional design and are shown only very schematically in Figure 2. By means of the loading device 101, the pallet changer 102 is loaded with sheets 2 to be processed. The loading device 101 picks up a sheet 2 to be placed on the pallet changer 102 from a stack of sheets.

[0049] Just like the laser cutting machine 10 and the suction frame 14 of the machine assembly 100, the loading device 101 and the pallet changer 102 are also controlled by a numerical assembly control 23. The monitoring and control of the machine assembly 100 for carrying out manufacturing processes for separating sheet metal processing is carried out in the same way as in the case of the machine assembly 1 according to Figure 1.
