A determination unit 22h, a joining instruction unit 22i, a correction value calculation unit 22j, and a memory 22k.

  In the sheet metal processing in the first embodiment, as shown in FIG. 2B, a cut portion 32 is formed by cutting four corners of one sheet metal 30 as shown in FIG. . Next, as shown in FIG. 3C, a plurality of predetermined holes are formed at predetermined positions. In the illustrated example, four rivet upper holes 34, four rivet pilot holes 36, and four position adjustment mark holes 38 are formed in the vicinity of each rivet pilot hole 36. Next, the sheet metal 30 is bent at predetermined bending lines 30a, 30b, 30c, and 30d. A panel 40 as shown in FIG. 3 is formed by connecting the bent metal plate 30 to the rivet upper hole 34 and the rivet lower hole 36 through the rivet.

  Next, in the first embodiment, processing executed in each part of the panel processing control apparatus 2A until the panel 40 is formed will be described with reference to each drawing.

  When the panel processing is started, the take-out instruction unit 22a first outputs a command to take out the sheet metal 30 from the storage warehouse 4 to the take-out device 6. The take-out device 6 takes out the sheet metal 30 one by one from the storage warehouse 4.

  Next, the cutting instruction unit 22 b outputs a cutting instruction for cutting the four corners of the sheet metal 30 to the cutting device 8. The cutting device 8 cuts four corners of the sheet metal 30 to form the cutting portions 32.

  When the cutting of the four corners of the sheet metal 30 is completed, the hole processing instruction unit 22c outputs a hole processing instruction to the hole processing apparatus 10 so as to open a predetermined hole at a predetermined position of the sheet metal 30. As shown in FIG. 2C, the hole machining apparatus 10 drills a rivet upper hole 34, a rivet lower hole 36, and a position adjustment mark hole 38 in the sheet metal 30. The position adjustment mark hole 38 is a long hole having a rectangular opening. The position adjustment mark hole 38 may not be a long hole but may be a rectangular hole having a square opening, or may be a marking such as painting or a position adjustment mark by marking.

  The bending process instruction unit 22d outputs a bending process instruction to the bending apparatus 12 (step S2 in FIG. 8). The bending apparatus 12 bends the sheet metal 30 along bending lines 30a, 30b, 30c, and 30d indicated by broken lines in FIG. 2C to form a panel 40 as shown in FIG.

  4 is a perspective view of the region indicated by a circle R in FIG. 3 as viewed from the A direction, and FIG. 5 is a perspective view of the region as viewed from the B direction, with the bent holes bent in the correct positional relationship. Is shown.

  The panel 40 after bending has long sides 40a and 40b opposite to each other and short sides 40c and 40d opposite to each other, and the position adjusting mark hole 38 is located on the long sides 40a and 40b. There are four places near 40d. That is, it is processed at a position where the short sides 40c and 40d are in contact with each other in a region where the short sides 40c and 40d are folded over the long sides 40a and 40b. When the long sides 40a and 40b and the short sides 40c and 40d are bent in the correct positional relationship, the rivet upper hole 34 and the rivet lower hole 36 overlap as a single hole without being displaced. . As will be described later, the position adjustment mark hole 38 is used for correction when the positional relationship between the rivet upper hole 34 and the rivet lower hole 36 is not the correct positional relationship and is shifted.

  When the bending is completed (YES in step S4), the photographing instruction unit 22e instructs the camera 16 to photograph the four corners of the panel 40 (step S6). As a result, the camera 16 photographs the four corners of the panel 40. The photographing area may be an area including at least the rivet upper hole 34, the rivet lower hole 36, and the position adjustment mark hole 38, and the number of times of photographing may be four at the four corners individually or four at the same time at the same time. Good.

  The image data input unit 22f inputs the captured image data and passes it to the distance calculation unit 22g (step S8).

  6A is a side view of a region indicated by a circle R in FIG. 3, and FIG. 6B is a plan view. As shown in FIG. 6, when the long sides 40a, 40b and the short sides 40c, 40d are bent in the correct positional relationship, the rivet upper hole 34 and the rivet lower hole 36 do not shift from each other. Overlapping like one hole. In this state, the edge 41d of the short side 40d is located on the center line of the position adjustment mark hole 38 so as to hide the right half of the position adjustment mark hole 38 in the drawing. At this time, the distance from the edge 41d to the end of the position adjustment mark hole 38, that is, the distance Xa from the center in the longitudinal direction of the position adjustment mark hole 38 to the end of the position adjustment mark hole 38, and the long side 40a A distance Ya from the edge 41a to the center in the short direction of the position adjustment mark hole 38 is defined as a reference distance (Xa, Ya). This reference distance (Xa, Ya) is stored in the memory 22k in advance.

  7A and 7B are a side view (A) and a plan view (B) when the sheet is not bent in the correct positional relationship.

  As shown in FIG. 7B, the distance calculation unit 22g is configured such that the distance (Xb) from the edge of the position adjustment mark hole 38 to the edge 41d of the short side 40d from the captured image data, the position adjustment mark hole The distance (Yb) from 13 center lines to the edge 41a of the long side 40a is calculated (step S10).

  The determination unit 22h reads the reference distance (Xa, Ya) of the position adjustment mark hole 13 from the memory 22k (step S12). The reference distance Xa and the calculated distance Xb, and the reference distance Ya and the calculated distance Yb are respectively compared. When the calculated distances Xb and Yb are within the reference range (step S14 YES), the joining instruction unit 22i instructs the joining device 14 to perform rivet joining (step S16).

  When the calculated distances Xb and Yb are out of the reference range (step S14 NO), the joining device 14 is stopped from rivet joining and a line-out instruction is given (step S18). Next, the correction value calculation unit 22j of the panel processing control apparatus 2A calculates the difference between the reference distance Xa and the calculation distance Xb and the difference between the reference distance Ya and the calculation distance Yb, respectively, and calculates the difference (deviation amount) as a correction value. Is stored in the memory 22k (step S20).

  The panel processing control device 2A calculates the previous bending size by adding a correction value to obtain the bending size (step S22). The corrected bending dimension is reflected in the next bending process.

  As described above, according to the first embodiment, the position correction of the mounting holes opened in the overlapping plates can be performed in the bending process based on the position of the position adjustment mark hole 38, and the hole processing position is set in the subsequent process. Occurrence of a situation of manual correction can be avoided.

  In the first embodiment, the shift amount is corrected in the bending process. However, the shift amount may be corrected in the drilling process. In this case, a correction value, which is a deviation amount, is added to the previous drilling dimension to obtain a new drilling dimension, which is reflected at the next drilling process.

Second Embodiment
Next, a second embodiment of the panel processing control apparatus will be described. FIG. 9 is a block diagram showing a configuration example of a panel processing system including a panel processing control apparatus according to the second embodiment. In addition, the same number is attached | subjected about the same component as 1st Embodiment shown in FIG. 1, and the description is abbreviate | omitted.

  In the first embodiment shown in FIGS. 1 to 8, an example in which the bending position is corrected when the mounting holes are deviated from each other is shown, but in the second embodiment, an example in which the hole machining position is corrected. Indicates. In this case, unlike the memory 22k of the first embodiment, the hole machining dimension and the correction value obtained by the determination unit 22h are stored in the memory 22m, and the hole machining dimension is corrected by this correction value. It is configured.

  A feature of the second embodiment is that a position adjustment mark hole 42 and a visual recognition hole 44 for visually recognizing the position adjustment mark hole 42 are formed in the metal plate 30.

  In the processing procedure of the sheet metal processing in the second embodiment, as shown in FIG. 10B, a cut portion 32 is formed by cutting four corners of a single sheet metal 30 as shown in FIG. To do. Next, as shown in FIG. 3C, a plurality of predetermined holes are formed at predetermined positions. In the illustrated example, four rivet upper holes 34, four rivet pilot holes 36, four position adjustment mark holes 42 in the vicinity of each rivet pilot hole 36, and each rivet upper hole. Four viewing holes 44 are opened near 34. Next, the sheet metal 30 is bent at predetermined bending lines 30a, 30b, 30c, and 30d. And the panel 50 as shown in FIG. 11 is formed by connecting the rivet upper hole 34 and the rivet lower hole 36 through the rivet to the bent metal plate 30.

  Next, in the second embodiment, processing executed in each part of the panel processing control apparatus 2B until the panel 50 is formed will be described.

  When the panel processing is started, the take-out instruction unit 22a first outputs a command to take out the sheet metal 30 from the storage warehouse 4 to the take-out device 6. The take-out device 2 takes out the sheet metal 30 one by one from the storage warehouse 4.

  Next, the cutting instruction unit 22 b outputs a cutting instruction for cutting the four corners of the sheet metal 30 to the cutting device 8. The cutting device 8 cuts four corners of the sheet metal 30 to form the cutting portions 32.

  When the cutting of the four corners of the sheet metal 30 is completed, the hole processing instruction unit 22c outputs a hole processing instruction to the hole processing apparatus 10 so as to open a predetermined hole at a predetermined position of the sheet metal 30. As shown in FIG. 2C, the hole machining apparatus 10 drills a rivet upper hole 34, a rivet lower hole 36, a position adjustment mark hole 42, and a visual recognition hole 44 in the sheet metal 30 (FIG. 16). Step S32).

  Here, the position adjustment mark hole 42 of the second embodiment is configured as a cross-shaped hole. Moreover, the visual recognition hole 44 is configured by a square opening. Note that the position adjustment mark hole 42 is not a hole but may be a marking for painting or the like and a position adjustment mark by marking. Further, the visual recognition hole 44 may be any hole that allows the position adjustment mark hole 42 to be seen through the opening when the short side is bent.

  When the hole processing is completed (YES in step S34), the bending process instruction unit 22d outputs a bending process instruction to the bending apparatus 12 (step S36). The bending apparatus 12 folds the sheet metal 30 along the fold lines 30a, 30b, 30c, and 30d shown by broken lines in FIG. 10C to form a panel 50 as shown in FIG.

  12 is a perspective view of a state before the region indicated by a circle R in FIG. 11 is folded along a folding line 30d as viewed from the C direction, and FIG. 13 is a perspective view after the folding.

  The panel 50 has long sides 50a and 50b facing each other and short sides 50c and 50d facing each other. The position adjustment mark holes 42 are provided at four locations on the long sides 50a and 50b and closer to the short sides 50c and 50d. The viewing holes 44 are provided at four locations on the short sides 50c and 50d and closer to the long sides 50a and 50b. That is, when the visual recognition hole 44 is correctly bent, the visual recognition hole 44 overlaps the position adjustment mark hole 42, and the center point of the cross forming the position adjustment mark hole 42 and the center point of the visual recognition hole 44 are Processed into overlapping positions.

  In addition, when the long sides 50a and 50b and the short sides 50c and 50d are bent in the correct positional relationship, the rivet upper hole 34 and the rivet lower hole 36 do not deviate from each other, and are like one hole. Overlapping. As will be described later, the position adjustment mark hole 42 and the visual recognition hole 44 are used for correction when the positional relationship between the rivet upper hole 34 and the rivet lower hole 36 is not the correct positional relationship and is shifted. .

  When the bending process is completed (step S38 YES), the photographing instruction unit 22e instructs the camera 16 to photograph the four corners of the panel 50 (step S40). As a result, the camera 16 photographs the four corners of the panel 50. The imaging area may be an area including at least the rivet upper hole 34, the rivet lower hole 36, and the position adjustment mark hole 42, and the number of imaging may be four times for each of the four corners, or once for the four corners at the same time. Good.

  The image data input unit 22f inputs the captured image data and passes it to the distance calculation unit 22g (step S42).

  14A is a side view of a region indicated by a circle R in FIG. 11, and FIG. 14B is a plan view. As shown in FIG. 14, when the long sides 50a and 50b and the short sides 50c and 50d are bent in the correct positional relationship, the rivet upper hole 34 and the rivet lower hole 36 do not deviate from each other. Overlapping like one hole. In this state, as shown in FIG. 14B, the position adjustment mark hole 42 is accommodated in the visual recognition hole 44, and the center of the cross coincides with the center of the visual recognition hole 44. Therefore, it is possible to grasp the correct positional relationship by inspecting image data captured by the camera 16.

  FIG. 15 is a side view (A) and a plan view (B) when holes are not drilled in the correct positional relationship.

  When the hole is not processed in the correct positional relationship, the position adjustment mark hole 42 appears to be shifted from the visual recognition hole 44. As shown in FIG. 15B, the distance calculation unit 22g checks the captured image data, and the distance (Xc) from the center lines 45 and 46 of the visual recognition hole 44 to the center of the position adjustment mark hole 42. The distance (Yc), that is, the amount of deviation is calculated (step S44).

  The determination unit 22h checks whether or not the calculated distance (Xc, Yc) is within the reference range. When the calculated distances Xc and Yc are within the reference range (step S46 YES), the joining instruction unit 22i instructs the joining device 14 to perform rivet joining (step S48).

  When the calculated distance (Xc, Yc) is out of the reference range (NO in step S46), the joining device 14 is stopped from rivet joining and a line-out instruction is given (step S50). Next, the calculation distance, that is, the deviation amount (Xc, Yc) is set as a correction value (step S52).

  The panel processing control device 2B calculates the previous drilling dimension by adding a correction value and sets it as the drilling position dimension (step S54). The corrected hole processing position dimension is reflected in the next hole processing. The panel processing control device 2B calculates the previous drilling position dimension by adding a correction value to obtain the hole processing position dimension. The panel processing control device 2B instructs the hole processing device 10 of the corrected hole processing position dimensions.

  As described above, according to the second embodiment, the position correction of the mounting holes opened in the overlapping plates is performed in the drilling process based on the positional relationship between the position adjustment mark holes 42 and the visual recognition holes 44. Therefore, it is possible to avoid the occurrence of a situation in which the hole machining position is manually corrected in a subsequent process.

  In the second embodiment, the amount of deviation is corrected in the drilling process, but the amount of deviation may be corrected in the bending process. In this case, a correction value, which is a deviation amount, is added to the previous bending dimension to obtain a new bending dimension, which is reflected in the next bending process.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
