Description

Technical Field

[0001] The present invention relates to a method for monitoring the situation of a processed product produced from a starting workpiece by separating a plate-type starting workpiece, in particular sheet metal, as part of a continuous manufacturing process, and the actual state of at least one parameter of the situation of the processed product is detected during the manufacturing process.

[0002] The present invention further relates to a method for controlling a continuous manufacturing process and to the manufacturing process, and as part of this method and process, the state of the processed product produced by separating the starting workpiece is monitored according to the aforementioned monitoring method.

[0003] The present invention also relates to a mechanical assembly for separating a plate-type workpiece, in particular sheet metal, and the mechanical assembly ● has a separating device capable of producing a processed product from a starting workpiece by separating the starting workpiece, ● has a monitoring device designed to detect the situation of the processed product, and the monitoring device has a detection device capable of detecting the actual state of at least one parameter of the situation of the processed product on the processed product.

[0004] Finally, the present invention relates to a computer program for operating a mechanical assembly of the aforementioned type.

[0005] The prior art of the type in question is disclosed in DE102020123555A1.

[0006] The prior art relates to a method and device for automated quality control of a cutting system for separating strips of fabric material. In a processing unit of a conventional known device, fabric material parts are produced by separating strips of fabric material. After their creation, the fabric material moves along a camera that detects the state of the fabric material. The device's control unit checks whether the detected state of the fabric material parts corresponds to the relevant specifications. If a defect is identified in the fabric material part, the control unit modifies selected parameters of the processing unit to eliminate the cause of the error and enable the subsequent production of defect-free fabric material parts.

[0007] The objective of this invention is to avoid, as much as possible, the production of defective processed products during the separation of workpieces, particularly sheet metal.

[0008] According to the present invention, this objective is achieved by the monitoring method described in claim 1, the control method described in claim 5, the manufacturing process described in claim 8, the machine assembly described in claim 9, and the computer program described in claim 18.

[0009] In this invention, the condition of the processed product to be produced by separating the starting workpiece is already detected prior to the production of the processed product, based on the area of ​​the starting workpiece that will form the processed product after separation. The actual state of at least one parameter of the starting workpiece condition is detected on the starting workpiece in a location-relevant manner. This means that it is known what the actual state of the parameters of the starting workpiece condition is in which area of ​​the starting workpiece. For the detection of the actual state of the parameters of the starting workpiece condition before separation, the machine assembly according to the present invention has a detection device located upstream of the separation device.

[0010] Simultaneously, for example, in the numerical control unit of the machine assembly according to the present invention, the nesting of the starting workpiece and the processed product stored for the starting workpiece already indicates which areas of the starting workpiece will form the processed product after separation, before the starting workpiece is separated. The evaluation device assigns the actual state of the parameters of the starting workpiece status identified for this area to the product-forming area of ​​the starting workpiece as the actual state of the processed product status.

[0011] The monitoring concept according to the present invention makes it possible to obtain knowledge about the status of the processed product in the early stages of a continuous manufacturing process and, if necessary, to intervene in the manufacturing process in a controllable manner.

[0012] A computer program according to the present invention controls a mechanical assembly according to the present invention to execute a manufacturing process according to the present invention, and for this purpose includes corresponding control commands for a numerical placement control unit.

[0013] Specific embodiments of the present invention according to independent claims 1, 5, 8, 9 and 18 will become apparent from dependent claims 2-4, 6, 7 and 10-17.

[0014] In a preferred embodiment of the method according to the present invention, the actual state of at least one parameter of the condition of the processed product is detected even after the separation of the starting workpiece. The detection is performed on the processed product (Claim 2). A machine assembly provided to implement this embodiment of the method according to the present invention comprises a monitoring device having a detection device located downstream of the separation device (Claim 10).

[0015] In a further embodiment of the method according to the present invention, the actual state of at least one parameter of the condition of the processed product, which remains unchanged during the further manufacturing process, is detected on the starting workpiece and / or the processed product (Claim 3). In this case, it is sufficient to detect the actual state of the condition parameter only once. The actual state of the parameter of the starting workpiece condition, detected on the starting workpiece, readily reflects the actual state of the condition of the processed product.

[0016] In further embodiments of the present invention, the thickness and / or surface condition and / or flatness and / or separation edge condition and / or dimensional accuracy of the processed product are monitored as conditional parameters particularly relevant to the quality of the processed product produced by separating the starting workpiece (claims 4 and 11).

[0017] In a further embodiment of the present invention, to control the machine assembly according to the present invention, the actual state of parameters relating to the condition of the processed product, as detected before and / or after the separation of the starting workpiece, is compared with an assigned target state. The manufacturing process and / or the machine assembly according to the present invention are controlled according to the comparison result (Claim 6).

[0018] In a more preferred embodiment, the machine assembly according to the present invention has a numerical arrangement control unit as described in claim 12 or 13.

[0019] When controlling a machine assembly according to the present invention, the overall status of the monitored continuous manufacturing process can also be taken into consideration (claims 7 and 14).

[0020] Information regarding the overall status of the continuous manufacturing process is optionally stored in the preferably programmable data memory of the numerical placement control unit of the machine assembly according to the present invention. For example, even before the separation of the starting workpiece, within the scope of the present invention, which monitors the status of the product forming area of ​​the starting workpiece, it may be determined that the determined status of the starting workpiece makes it impossible to produce a processed product of the desired quality using the continuous process. At the same time, if the information stored in the data memory of the numerical placement control unit indicates that the status of the starting workpiece, which is unsuitable for the current process, meets the quality requirements of a manufacturing process planned after the current manufacturing process, the numerical placement control unit can terminate the current manufacturing process and bring forward the later planned manufacturing process.

[0021] In a more preferred embodiment of the present invention, the data memory relating to the overall status of the continuous manufacturing process is part of an ERP (Enterprise Resource Planning) system (Claim 15).

[0022] An unloading device, which is located on the supply side of a machine assembly separation device and / or a supply device capable of supplying a start workpiece to the separation device and / or an unloading device located on the discharge side of a separation device capable of discharging a processed product from the separation device, is particularly suitable as a functional unit of the machine assembly according to the present invention, and these functional units are controlled in accordance with the status of the processed product monitored before and / or after the separation of the start workpiece (Claim 16).

[0023] A particularly practical application of the present invention is the separation of sheet metal from coils (Claim 17). During the separation of sheet metal from coils, the output of the processed product is very high. Against this backdrop, it is especially important to detect the quality of the manufactured product as quickly as possible and, if necessary, to influence the continuous manufacturing process as quickly as possible.

[0024] The present invention will be described in more detail below based on an illustrative schematic diagram.

Brief Description of the Drawings

[0025] [Figure 1] It shows a mechanical assembly for separating sheet metal from a coil. [Figure 2] It shows a mechanical assembly for separating a sheet metal panel.

[0026] According to FIG. 1, the mechanical assembly 1 is used to process the sheet metal 2 wound around the reel 4 in the form of a coil 3. Adjacent to the reel 4, there is a leveling device 5 of a conventional design having leveling rollers 6.

[0027] The leveling rollers 6 are provided in a normal manner with a controllable motor drive and are part of the supply device 7, whereby the sheet metal 2 is partially unwound from the coil 3 and moves in the supply direction 8 into the working space 9 of a laser cutting machine 10 provided as a separation device.

[0028] In the example shown, the very schematically illustrated laser cutting machine 10 is a conventional laser flat bed machine. The sheet metal 2 is supplied section by section by the supply device 7 as the starting workpiece to be separated to the workpiece support of the laser cutting machine. During separation, the laser cutting head (not shown) of the laser cutting machine 10 moves over the section of the sheet metal 2 placed on the workpiece support of the laser cutting machine 10 by a two-axis horizontal movement in a known manner.

[0029] In this case, from the sheet metal 2, as processed products, a sheet metal workpiece 11 and a residual grid 12 surrounding the sheet metal workpiece 11 are also produced.

[0030] After separation is complete, the sheet metal 2 moves further in the supply direction 8. As a result, the processed section of the sheet metal 2 is transported to the unloading table 13 located downstream of the laser cutting machine 10 in the supply direction 8. At the same time, the still unprocessed section of the sheet metal 2 is moved to its processing position on the workpiece support of the laser cutting machine 10 as a new starting workpiece.

[0031] On the unloading table 13, the sheet metal workpiece 11 is picked up by a conventional suction frame 14 that functions as an unloading device, and is sent by the suction frame 14 to a storage area 15 where a first workpiece storage area 16 and a second workpiece storage area 17 are provided. The residual grid 12 that initially remains on the unloading table 13 is divided by a device not shown and then also removed from the unloading table 13.

[0032] Similar to the supply device 7 and the laser cutting machine 10, the suction frame 14 also forms a functional unit of the machine assembly 1.

[0033] The status of the sheet metal workpiece 11 produced on the machine assembly 1 is continuously monitored during the continuous separation manufacturing process. For this purpose, the 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 positioned 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. A further camera 21a is provided as a detector for the third detection device 21 near the unloading table 13.

[0035] The first detection device 19, the second detection device 20, and the third detection device 21 share a common numerical detection unit 22. A sheet thickness gauge 19a, as well as cameras 20a and 21a, are connected to this unit. The numerical detection unit 22 is part of the numerical placement control unit 23 of the machine assembly 1.

[0036] In the illustrated example, the thickness of the sheet 2 after it has been removed from the coil 3 is determined by the first detection device 19. In the illustrated example, the second detection device 20 is used to determine the surface condition of the sheet metal 2 after it has left the straightening device 5, and the third detection device 21 is used to determine the condition of the separated edges of the sheet metal workpiece 11 after it has left the working space 9 of the laser cutting machine 10 and been transported to the unloading table 13. Due to the arrangement of the sheet thickness gauge 19a and the cameras 20a and 21a, the first detection device 19 and the second detection device 20 are located upstream of the laser cutting machine 10, and the third detection device 21 is located downstream of the laser cutting machine 10.

[0037] The actual state of the thickness and surface condition of the sheet metal 2 detected by the first detection device 19 and the second detection device 20, as well as the separation edge condition of the sheet metal workpiece 11 detected by the third detection device 21, are evaluated by the evaluation unit 24 of the numerical placement control unit 23.

[0038] In the continuous manufacturing process, the sheet metal 2 wound from the coil 3 is intermittently moved in the supply direction 8 by the supply device 7 over a partial supply length that coincides with the extension of the workpiece support in the supply direction 8 and the range of the laser cutting head in the working space 9 of the laser cutting machine 10. The movement of the partial supply length of the sheet metal 2 in the supply direction 8 is defined with the help of the path measuring system of the supply device 7. As a result, the partial supply length of the sheet 2 detected by the sheet thickness measuring device 19a with respect to thickness, and / or the partial supply length of the sheet 2 detected by the camera 20a with respect to surface condition, is ensured to reach a defined processing position in the working space 9 of the laser cutting machine 10 during movement in the supply direction 8. At the same time, the assignment of the sheet metal workpiece 11 to the partial supply portion of the unprocessed sheet 2 is stored in unit 24 of the numerical placement control unit 23 of the machine assembly 1. As a result, the evaluation unit 24 can identify on the unprocessed sheet metal 2 (starting workpiece) region of a partial supply length, which was scanned in cross-section before separation by the sheet metal thickness measuring device 19a and camera 20a, and which will form the sheet metal workpiece 11 (processed product) as the product formation region of the starter workpiece after separation by the laser cutting machine 10.

[0039] The evaluation device 24 assigns the actual thickness of the unprocessed portion of the sheet metal 2 detected by the first detection device 19 as the actual thickness of the sheet metal workpiece 11, and the actual surface condition of the unprocessed portion of the sheet metal 2 detected by the second detection device 20 as the actual surface condition of the sheet metal workpiece 11, and assigns this to the product forming area of ​​the unprocessed portion of the sheet metal 2. This assignment is easily possible because the actual conditions detected by the first detection device 19 and the second detection device 20 remain unchanged during the further manufacturing process.

[0040] The third detection device 21 directly detects the separation edge status of the sheet metal workpiece 11 placed on the unloading table 13 on the sheet metal workpiece 11 after the sheet metal has been separated.

[0041] In the evaluation unit 24, the actual state of the sheet metal workpiece 11—its thickness, surface condition, and separation edge condition—is compared with the target state of these three parameters stored in the evaluation unit 24. Depending on the result of the comparison between the actual state and the target state, the supply device 7, the laser cutting machine 10, and the suction frame 14 are controlled by the control device 25 of the numerical placement control unit 23 using corresponding control commands.

[0042] In the evaluation unit 24, if a deviation is detected between the actual state and the target state while comparing the monitoring parameters of the sheet metal workpiece 11, the control unit 25 generates a control command for the relevant functional unit of the machine assembly 1 to adapt the detected actual state to the relevant target state.

[0043] For example, if the first detection device 19 determines that the thickness of the product-forming area of ​​the unprocessed sheet metal 2 deviates from the thickness of the sheet metal workpiece 11 specified for the continuous manufacturing process, the control unit 25 can stop the supply device 7 with a corresponding control command, thereby halting the separation of the sheet metal 2 immediately after the start of sheet metal supply, and as a result, the production of a poor-quality sheet metal workpiece 11 is avoided from the outset.

[0044] In the exemplary case shown, the numerical placement control unit 23 can also consider the overall situation of the continuous manufacturing process when controlling the machine assembly 1. Such an overall situation is stored in the programmable data memory 26 of the numerical placement control unit 23. The data memory 26 is part of the ERP (Enterprise Resource Planning) system.

[0045] In this exemplary case, the data memory 26 contains information about a manufacturing process that differs from the continuous manufacturing process only in that it has requirements regarding the surface quality of the sheet metal workpiece 11, which is executed and manufactured by the machine assembly 1 following the continuous manufacturing process.

[0046] If the evaluation unit 24 determines that the surface condition of the sheet metal workpiece 11 detected by the second detection device 20 does not meet the quality requirements of the current manufacturing process but does meet the quality requirements of a later planned manufacturing process, the control unit 25 can halt the current manufacturing process and bring forward the later planned manufacturing process. Similarly, the numerical placement control unit 23 can control the machine assembly 1 if the thickness of the sheet metal workpiece 11 detected by the first detection device 19 does not meet the current requirements but meets the requirements of a later planned manufacturing process.

[0047] The knowledge of the actual state of the cutting edge condition of the sheet metal workpiece 11 obtained by the third detection device 21 is taken into consideration by the numerical placement control unit 23 when controlling the suction frame 14. If the third detection device 21 determines that the cutting edge condition of the sheet metal workpiece 11 conforms to the specifications of the continuous manufacturing process, the control device 25 controls the suction frame 14 to transport the sheet metal workpiece 11 to the first workpiece storage area 16 of the storage area 15. If the cutting edge condition of the sheet metal workpiece 11 detected by the third detection device 21 does not meet the specified quality requirements, the suction frame 14 is controlled by the control unit 25 to transport the sheet metal workpiece 11 to the second workpiece storage area 17. The second workpiece storage area 17 is for sheet metal workpieces 11 that require rework of the separated edges.

[0048] In the exemplary case shown, information obtained during the monitoring and control of machine assembly 1 as part of a continuous manufacturing process is transmitted to a data integration platform 27, which will be accessible in future manufacturing processes.

[0049] The machine assembly 100 shown in Figure 2 differs from the machine assembly 1 shown in Figure 1 in that the sheet metal 2 to be separated is in the form of sheet metal panels rather than coils. During processing, the sheet metal panels are stored on a conventional workpiece pallet within the working area 9 of the laser cutting machine.

[0050] Therefore, the supply device 7 of the machine assembly 100 comprises a loading device 101 and a pallet changer 102, rather than the straightening device shown in Figure 1. The loading device 101 and pallet changer 102 are of a conventional design and are shown only in a very schematic form in Figure 2. The loading device 101 loads the sheet metal 2 to be processed into the pallet changer 102. The sheet metal 2 placed in the pallet changer 102 is removed from the sheet metal stack by the loading device 101.

[0051] Similar to the laser cutting machine 10 and suction frame 14 of the machine assembly 100, the loading device 101 and pallet changer 102 are also controlled by the numerical placement control unit 23. Monitoring and control of the machine assembly 100 for carrying out the manufacturing process for separating sheet metal is performed in the same manner as in the example of machine assembly 1 shown in Figure 1.
