Description

Technical Field

[0001] This invention relates to the field of sponge processing, and in particular to an automatic width measuring and tool setting method for sponge processing. Background Technology

[0002] With the development and popularization of technology, industrial automation has become the mainstream. The application of automation in the production process of sponge products is also becoming more and more widespread, from foam storage, maturation, and transfer to subsequent conveying to intelligent cutting lines and material flow, all of which can be automated.

[0003] Currently, in the production of sponge products, whether the foamed sponge blocks are sent to the intelligent cutting line for initial cutting or the sliced ​​sponge sheets are sent to the intelligent cutting line for secondary cutting, conveyor belts are generally used to transport the foam blocks or sheets. This method inevitably leads to displacement between the foam blocks / sheets and the conveyor belt during transport, causing the foam blocks / sheets to shift or tilt, thus affecting the accuracy of subsequent sponge cutting. Furthermore, since the size of the sponge is fixed and the cutting path of the intelligent cutting line is also fixed, any shift in the sponge's shape will reduce its actual utilization rate and increase the company's costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic width measurement and tool setting method for sponge processing that can ensure the accuracy of sponge cutting.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic width measuring and tool setting method for sponge processing, the innovation of which is: including the following steps

[0006] S1: First, the sponge cutting machine automatically obtains the processing orders, grabs the processing orders at a designated time according to the preset location, obtains the order information, and automatically organizes them into processing tasks according to the preset rules of the sponge cutting machine;

[0007] S2: Based on the order information of the processing order, send the required cotton type information to the warehouse, select the corresponding cotton foam in the warehouse for processing, and after the cotton foam is sent out of the warehouse, it is transported to the sponge cutting machine via conveyor belt.

[0008] S3: The conveyor belt at the sponge cutting machine is defined as the main platform and the extension platform. The main platform is located directly below the sponge cutting machine, and the extension platform is located on the feeding side of the main platform. Three distance measuring detection points are set on the extension platform, namely the first detection point, the second detection point and the third detection point. The first detection point and the second detection point are located on both sides of the width direction of the conveyor belt, and the first detection point and the third detection point are distributed along the conveying direction of the conveyor belt. The third detection point is located in front of the first detection point. Photoelectric switches are installed at each distance measuring detection point, namely the first photoelectric switch installed at the first detection point, the second photoelectric switch installed at the second detection point and the third photoelectric switch installed at the third detection point.

[0009] The three distance measurement detection points correspond to variables #"1 distance", #"2 distance", and #"3 distance, respectively. The real-time value of variable #"1 distance" is the tool setting coordinate. The distance between the first and second detection points is a fixed value, defined as variable #"12 distance". The distance between the first and third detection points is a fixed value, defined as variable #"13 distance.

[0010] When the foam is conveyed between the first and second detection points, the actual width of the foam is measured and defined as the variable #hypotenuse. The actual width is equal to the distance between the first and second detection points minus the measured value between the first and second detection points. The formula is expressed as #hypotenuse:=#"12 spacing"-#"1 distance"-#"2 distance".

[0011] Four recording points are also set on the conveyor belt: recording point A and recording point B at the first detection point, recording point C at the second detection point, and recording point D at the third detection point. Recording point A and recording point D are the endpoints of two actual positions of the foam along the conveying direction, and recording point B and recording point C are two theoretical cutting points of the foam along the width direction of the conveyor belt.

[0012] The length between recording point A and recording point B is the difference between the measurement data of the first detection point and the third detection point, defined as variable #"13 difference". Then #"13 difference":=ABS(#"1 distance"-#"3 distance");

[0013] The distance between recording point A and recording point D is defined as the hypotenuse of variable #. The length of hypotenuse # is calculated according to the formula: #hypotenuse:=SQRT(SQR(#"13 difference")+SQR(#"13 spacing")).

[0014] The width of the foam is defined as the variable #foam width, and the formula is #foam width := #hypotenuse * (#"13 spacing" / #middle hypotenuse);

[0015] The tilt angle of the foam is defined as the variable #tilt angle, and the formula is #tilt angle:=180*ACOS(#"13 spacing" / #middle hypotenuse) / 3.14;

[0016] S4: Sponge-on-blade alignment. A sensor is set at the sponge-on direction of the main platform to record the position of the sponge bubble on the main platform. At the same time, the distance between the sensor and the blade of the sponge cutter is fixed. When the sensor detects the sponge bubble, it records the coordinate A of the main platform.

[0017] #Main platform coordinates A:="HMI".Main platform status.Actual location;

[0018] Then the tool coordinates are equal to the main platform coordinates A plus the distance from the sensor to the tool:

[0019] #Tool setting coordinates Y:=#Main platform coordinates A+"HMI".Process parameters[5]=#"1 distance";

[0020] S5: Calculate the number of pieces to be chopped. Based on the length of the main platform, the required piece length, and the available dimensions of the edge skin, calculate the number of pieces to be chopped at one time. Compare the required piece length with the edge skin length. The larger value is designated as #A, and the smaller value is designated as #B. The two values ​​are then used for a loop calculation with remainders.

[0021] WHILE#B<>0DO

[0022] #zzzzz:=#AMOD#B;

[0023] #A:=#B;

[0024] #B:=#zzzzz;

[0025] END_WHILE;

[0026] Then calculate the least common multiple of the two:

[0027] Least common multiple: = # edge layer * # block length / # A;

[0028] If the platform length is less than the least common multiple, then the maximum number of slices is equal to the platform length divided by the block length.

[0029] If the platform length is greater than the least common multiple, then the maximum number of slices is equal to the least common multiple and the block length.

[0030] The number of workpieces processed in one operation can be obtained from the above calculations.

[0031] S6: Path planning. First, calculate the displacement length of each segment of the foam. After obtaining the displacement length of each segment, plan the route based on the data of each segment displacement length. First, walk from the starting point to the ending point in the cutting direction to adjust the end face. Then, retreat by the thickness of one edge skin. Next, the main platform moves forward by the first displacement distance. After the platform moves to the position, it continues to move towards the ending point in the cutting direction once more to cut off the first edge skin. Then, it retreats back to the edge skin cutting position. The main platform continues to move forward by the second displacement distance. This cycle continues until the next displacement distance is zero, at which point the cutting is complete.

[0032] Furthermore, when the foam is conveyed to the sponge cutting machine by the conveyor belt, the length of the foam needs to be measured. There are two methods for measuring the length:

[0033] The first method for measuring length is:

[0034] When the first photoelectric switch detects that the bubble has reached the recording point A, the coordinates are #variable extension stage coordinates A, #extension stage coordinates A:="HMI".extension stage status.actual position;

[0035] When the first photoelectric switch detects that the bubble leaves the recording point B, the coordinates are variable #extension stage coordinates B, #extension stage coordinates B:="HMI".extension stage status.actual position;

[0036] The length of the bubble is equal to the positional difference between the two points:

[0037] #Bubble length:=#Extension stage coordinates B-#Extension stage coordinates A;

[0038] The second method for measuring length is:

[0039] When the first photoelectric switch detects that the bubble leaves the recording point A, the coordinates of that point are variable #extension stage coordinates A, #extension stage coordinates A:="HMI".extension stage status.actual position;

[0040] When the second photoelectric switch detects that the bubble has reached the recording point B, the coordinates are variable #extension stage coordinates B, #extension stage coordinates B:="HMI".extension stage status.actual position;

[0041] The length of the bubble is equal to the distance between the two points minus the difference in their positions.

[0042] #Bubble length:="HMI".Process parameters

[20] -(#Extension stage coordinates B-#Extension stage coordinates A).

[0043] Furthermore, when the tilt angle of the foam exceeds a certain value, the utilization rate of the sponge will be greatly reduced. Based on this, a threshold for the tilt angle of the foam is defined, and an alarm will be triggered if this value is exceeded.

[0044] Furthermore, in step S6, the method for calculating the displacement length of each segment of the foam is as follows:

[0045] If the number of bubbles chopped at one time is 1, the displacement distance is the processing length:

[0046] #Displacement distance[0]:="HMI".Process parameters[8];

[0047] If the number of parts processed at one time is greater than 1, and the edge length is less than or equal to the number of parts processed in one cycle multiplied by the edge length, the displacement distance is the edge length:

[0048] Then #displacement distance[0]:="HMI".process parameters

[10] ;

[0049] If the total length of a single processing operation is less than the length of two edge pieces, then the displacement distance of the second segment is equal to the total length minus the displacement distance of the first segment.

[0050] Then #displacement distance[1]:="HMI".process parameter

[22] *"HMI".process parameter[8]-"HMI".process parameter

[10] ;

[0051] If the total length of a single processing step is less than the length of three edge pieces but greater than the length of two edge pieces, then the displacement distance of the second segment is equal to the length of the edge piece.

[0052] #Displacement distance[1]:="HMI".Process parameters

[10] ;

[0053] The length of the third displacement segment is equal to the total length minus the lengths of the two side edges:

[0054] Then #displacement distance[2]:="HMI".process parameter

[22] *"HMI".process parameter[8]-"HMI".process parameter

[10] *2;

[0055] The distance required for each displacement is calculated in the same way.

[0056] The advantages of this invention are as follows: When using this invention in conjunction with a sponge cutting machine to cut foam, by measuring the width of the foam and setting the blade accordingly, and by monitoring the displacement of the foam in real time, the cutting position of the blade can be adjusted according to the real-time position of the foam during subsequent cutting, thereby improving the cutting accuracy of the sponge. At the same time, the actual utilization rate of the sponge is also improved, waste is reduced, and enterprise costs are lowered. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0058] Figure 1 This is a real-time position diagram of the foam on the conveyor belt in this invention. Implementation

[0059] The following embodiments are intended to enable those skilled in the art to more fully understand the present invention, but do not limit the invention to the scope of the embodiments described.

[0060] The automatic width measurement and tool setting method for sponge processing of the present invention includes the following steps:

[0061] S1: First, the sponge cutting machine automatically obtains the processing orders, and according to the preset rules, it grabs the processing orders at designated positions at regular intervals, obtains the order information, and automatically organizes them into processing tasks according to the preset rules of the sponge cutting machine.

[0062] S2: Based on the order information of the processing order, send the required cotton type information to the warehouse, select the corresponding cotton foam in the warehouse for processing, and after the cotton foam is sent out of the warehouse, it is transported to the sponge cutting machine via conveyor belt.

[0063] S3: The conveyor belt at the sponge cutting machine is defined as the main platform and the extension platform. The main platform is located directly below the sponge cutting machine, and the extension platform is located on the feeding side of the main platform. Three distance measuring detection points are set on the extension platform, namely the first detection point, the second detection point, and the third detection point. The first detection point and the second detection point are located on both sides of the width direction of the conveyor belt, respectively. The first detection point and the third detection point are distributed along the conveying direction of the conveyor belt, and the third detection point is located in front of the first detection point. Photoelectric switches are installed at each distance measuring detection point, namely the first photoelectric switch installed at the first detection point, the second photoelectric switch installed at the second detection point, and the third photoelectric switch installed at the third detection point.

[0064] The three distance measurement detection points correspond to variables #"1 distance", #"2 distance", and #"3 distance, respectively. The real-time value of variable #"1 distance" is the tool setting coordinate. The distance between the first and second detection points is a fixed value, defined as variable #"12 distance". The distance between the first and third detection points is a fixed value, defined as variable #"13 distance.

[0065] When the foam is conveyed between the first and second detection points, the actual width of the foam is measured and defined as the variable #hypotenuse. The actual width is equal to the distance between the first and second detection points minus the measured value between the first and second detection points. The formula is expressed as #hypotenuse:=#"12 spacing"-#"1 distance"-#"2 distance".

[0066] Four recording points are also set on the conveyor belt: recording point A and recording point B at the first detection point, recording point C at the second detection point, and recording point D at the third detection point. Recording point A and recording point D are the endpoints of two actual positions of the foam along the conveying direction, and recording point B and recording point C are two theoretical cutting points of the foam along the width direction of the conveyor belt.

[0067] The length between recording point A and recording point B is the difference between the measurement data of the first detection point and the third detection point, defined as variable #"13difference". Then #"13difference":=ABS(#"1 distance"-#"3 distance").

[0068] The distance between recording point A and recording point D is defined as the hypotenuse of variable #. The length of hypotenuse # is calculated according to the formula: #hypotenuse:=SQRT(SQR(#"13 difference")+SQR(#"13 spacing")).

[0069] The width of the foam is defined as the variable #foam width, and the formula is #foam width := #hypotenuse * (#"13 spacing" / #middle hypotenuse);

[0070] The tilt angle of the foam is defined as the variable #tilt angle, and the formula is #tilt angle:=180*ACOS(#"13 spacing" / #middle hypotenuse) / 3.14.

[0071] When calculating the tilt of the foam, the utilization rate of the sponge will be greatly reduced when the tilt of the foam exceeds a certain value. Based on this, a threshold for the tilt of the foam is defined. If the tilt exceeds the threshold, an alarm will be triggered to remind nearby staff to correct the position of the foam in order to avoid the foam's utilization rate being reduced during subsequent cutting due to excessive tilt.

[0072] When the foam is conveyed to the sponge cutting machine by the conveyor belt, in addition to measuring the width of the foam, it is also necessary to measure the length of the foam. There are two methods for measuring the length of the foam:

[0073] The first method for measuring length is:

[0074] When the first photoelectric switch detects that the bubble has reached the recording point A, the coordinates are #variable extension stage coordinates A, #extension stage coordinates A:="HMI".extension stage status.actual position;

[0075] When the first photoelectric switch detects that the bubble leaves the recording point B, the coordinates are variable #extension stage coordinates B, #extension stage coordinates B:="HMI".extension stage status.actual position;

[0076] The length of the bubble is equal to the positional difference between the two points:

[0077] #Bubble length:=#Extension stage coordinates B-#Extension stage coordinates A.

[0078] The second method for measuring length is:

[0079] When the first photoelectric switch detects that the bubble leaves the recording point A, the coordinates of that point are variable #extension stage coordinates A, #extension stage coordinates A:="HMI".extension stage status.actual position;

[0080] When the second photoelectric switch detects that the bubble has reached the recording point B, the coordinates are variable #extension stage coordinates B, #extension stage coordinates B:="HMI".extension stage status.actual position;

[0081] The length of the bubble is equal to the distance between the two points minus the difference in their positions.

[0082] #Bubble length:="HMI".Process parameter

[20] -(#Extension stage coordinate B-#Extension stage coordinate A), where process parameter

[20] represents the distance between recording point A and recording point B.

[0083] Both of the above methods can be used to measure the length of the foam; either method can be chosen based on actual needs.

[0084] S4: Sponge-on-blade alignment. A sensor is set at the sponge-on direction of the main platform to record the position of the sponge bubble on the main platform. At the same time, the distance between the sensor and the blade of the sponge cutter is fixed. When the sensor detects the sponge bubble, it records the coordinate A of the main platform.

[0085] #Main platform coordinates A:="HMI".Main platform status.Actual position.

[0086] The tool coordinates are then equal to the main platform coordinates A plus the distance from the sensor to the tool.

[0087] #Tool Coordinate Y:=#Main Platform Coordinate A+"HMI".Process Parameter[5]=#"1 Distance", where the process parameter[5] represents the distance from the sensor to the tool of the sponge cutter.

[0088] S5: Calculate the number of pieces to be chopped. Based on the length of the main platform, the required piece length, and the available dimensions of the edge skin, calculate the number of pieces to be chopped at one time. Compare the required piece length with the edge skin length. The larger value is designated as #A, and the smaller value is designated as #B. The two values ​​are then used for a loop calculation with remainders.

[0089] WHILE#B<>0DO

[0090] #zzzzz:=#AMOD#B;

[0091] #A:=#B;

[0092] #B:=#zzzzz;

[0093] END_WHILE.

[0094] Then calculate the least common multiple of the two:

[0095] #Least common multiple:=#edge skin *#block length / #A.

[0096] If the platform length is less than the least common multiple, then the maximum number of slices is equal to the platform length divided by the block length.

[0097] If the platform length is greater than the least common multiple, then the maximum number of slices is equal to the least common multiple of the block length.

[0098] The number of workpieces processed in one operation can be obtained from the above calculations.

[0099] S6: Path planning. First, calculate the displacement length of each segment of the foam. The calculation method for the displacement length of each segment of the foam is as follows:

[0100] If the number of bubbles chopped at one time is 1, the displacement distance is the processing length:

[0101] #Displacement distance[0]:="HMI".Process parameter[8], where process parameter[8] represents the length of the foam;

[0102] If the number of parts processed at one time is greater than 1, and the edge length is less than or equal to the number of parts processed in one cycle multiplied by the edge length, the displacement distance is the edge length:

[0103] Then #displacement distance[0]:="HMI".process parameter

[10] , where process parameter

[10] represents a side skin length.

[0104] If the total length of a single processing operation is less than the length of two edge pieces, then the displacement distance of the second segment is equal to the total length minus the displacement distance of the first segment.

[0105] Then #displacement distance[1]:="HMI".process parameter

[22] *"HMI".process parameter[8]-"HMI".process parameter

[10] ; here, process parameter

[22] represents the number of workpieces to be processed.

[0106] If the total length of a single processing step is less than the length of three edge pieces but greater than the length of two edge pieces, then the displacement distance of the second segment is equal to the length of the edge piece.

[0107] #Displacement distance[1]:="HMI".Process parameters

[10] ;

[0108] The length of the third displacement segment is equal to the total length minus the lengths of the two side edges:

[0109] Then #displacement distance[2]:="HMI".process parameter

[22] *"HMI".process parameter[8]-"HMI".process parameter

[10] *2;

[0110] The distance required for each displacement is calculated in the same way.

[0111] After obtaining the displacement length of each segment, the route is planned based on the displacement length data of each segment. First, the platform moves from the starting point to the ending point in the cutting direction to adjust the end face. Then, it moves back by the thickness of one edge skin. Next, the main platform moves forward by the first displacement distance. Once the platform is in place, it continues to move towards the ending point in the cutting direction once more to cut off the first edge skin. Then, it moves back to the edge skin cutting position and the main platform continues to move forward by the second displacement distance. This cycle continues until the next displacement distance is zero, at which point the cutting is complete.

[0112] When using this invention in conjunction with a sponge cutting machine to cut foam, the width of the foam is measured and the blade is aligned, and the displacement of the foam during movement is monitored in real time. This allows the cutting position of the blade to be adjusted according to the real-time position of the foam during subsequent cutting, thereby improving the cutting accuracy of the sponge. At the same time, the actual utilization rate of the sponge is also improved, reducing waste and lowering enterprise costs.

[0113] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
