Method and device for continuously cutting flexible fabrics

Abstract

The present invention provides a method and apparatus for continuously cutting flexible fabrics. When a vacuum adsorption conveying mechanism adsorbs and begins conveying the fabric, the method obtains the fabric's pattern data to be cut and calculates the maximum and minimum distances in the conveying direction for each pattern data to be cut. Then, based on the maximum and minimum distances in the conveying direction, the position of each pattern to be cut on the fabric is calculated to obtain cutting position data. Each pattern to be cut is then sorted to obtain a sorting result. Finally, based on the cutting position data and the cutting contour, a multi-axis drive device is used to drive the cutting head to preferentially cut the fabric at the position of the pattern to be cut with the smallest sorting result. At this time, the vacuum adsorption conveying mechanism uses a parallel process to convey the fabric. Compared to the prior art, the present invention solves the problems of fabric loosening and cutting misalignment caused by pressure relief in the prior art, thereby greatly improving cutting quality.

Description

Technical Field

[0001] This invention belongs to the field of cutting equipment technology, specifically relating to a method and equipment for continuous cutting of flexible fabrics. Background Technology

[0002] Fabric cutting equipment is an automated cutting device specifically designed for cutting multi-layered fabrics. It is widely used in the cutting of clothing, interior decorations, and furniture. The fabric cutting equipment mainly consists of a vacuum adsorption conveying mechanism and a multi-axis cutting mechanism. The vacuum adsorption conveying mechanism is used to adsorb multi-layered flexible fabrics, "hardening" the flexible fabric to prevent fabric misalignment during multi-axis cutting.

[0003] Existing fabric cutting equipment has the following shortcomings:

[0004] 1. Traditional equipment divides the fabric roll into multiple segments for cutting during the cutting process. Each segment remains static during the cutting process. After the cutting is completed, it is then transported to a collection device or collected manually, which is inefficient and not safe enough.

[0005] 2. For fabrics with high adsorption requirements, if segmented static cutting is used, gaps will appear between the cut sample and the fabric roll in the segmented area. This gap will cause the adsorption surface of the vacuum adsorption conveyor to depressurize. In addition, the fabric roll that is kept static will be loose at this time, making it difficult for the fabric section itself to maintain "hardening", which will cause the cutting to shift and seriously affect the cutting quality.

[0006] 3. In the continuous automated cutting process, the cutting head in the multi-axis cutting mechanism needs to extend into multiple layers of fabric for cutting. The cutting process inevitably leads to wear and dulling of the cutting head, which seriously affects cutting efficiency and cutting quality. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a method and apparatus for continuous cutting of flexible fabrics, thereby solving the problems existing in the prior art.

[0008] In a first aspect, to achieve the above objective, the present invention provides a method for continuously cutting a flexible fabric, comprising:

[0009] S10: Employs a multi-threaded control device to independently drive the vacuum adsorption conveying mechanism, the multi-axis cutting mechanism, and the positioning device;

[0010] The multi-axis cutting mechanism includes a multi-axis drive device and a cutting head disposed at the drive end of the multi-axis drive device; the vacuum adsorption conveying mechanism includes a conveyor belt and a vacuum adsorption platform disposed on the conveyor belt.

[0011] S20: When the vacuum adsorption conveying mechanism adsorbs and starts conveying the fabric, acquire the fabric pattern data to be cut, and calculate the maximum and minimum conveying distances in the conveying direction for each pattern data to be cut.

[0012] Wherein, the pattern data to be cut includes the cutting outline; the maximum distance in the conveying direction refers to the distance between the endpoint of the cutting outline furthest from the vacuum adsorption platform outlet and the end of the vacuum adsorption platform; the minimum distance in the conveying direction refers to the distance between the endpoint of the cutting outline closest to the vacuum adsorption platform outlet and the end of the vacuum adsorption platform.

[0013] S30: Calculate the position of each pattern to be cut on the fabric based on the maximum and minimum distances in the conveying direction to obtain the cutting position data;

[0014] S40: Sort each pattern to be cut according to the minimum distance in the conveying direction, and obtain the sorting result;

[0015] Among them, the pattern to be cut with the smaller minimum distance in the conveying direction is ranked earlier;

[0016] S50: Based on the cutting position data and cutting outline, a multi-axis drive device is used to drive the cutting head to prioritize cutting the fabric at the position of the pattern to be cut with the smallest sorting result.

[0017] S60: The positioning device monitors the fabric on the vacuum adsorption conveying mechanism in real time. If the positioning device detects that the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result is greater than the preset threshold, it sends a command to the vacuum adsorption conveying mechanism to continue adsorbing and conveying the fabric; otherwise, the positioning device sends a stop conveying command to the vacuum adsorption conveying mechanism.

[0018] S70: The cut fabric is removed from the vacuum adsorption conveyor and sent to the receiving table;

[0019] S50-S60 execute independently without interfering with each other.

[0020] Through the above technical solution, S50 uses a multi-axis drive device to drive the cutting head to prioritize cutting the fabric at the position of the pattern to be cut with the smallest sorting result, based on the cutting position data and cutting contour. S60 uses a positioning device to monitor the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result in real time, to determine whether this minimum distance is less than a preset threshold, and to decide whether the vacuum adsorption conveying mechanism needs to stop conveying. That is, S50 and S60 in the method of the present invention are independent parallel processes, and fabric cutting is performed simultaneously during fabric conveying, which improves the efficiency of fabric cutting. The entire process does not require personnel assistance, thus improving the safety of fabric cutting. Compared with the prior art, the fabric in the method of the present invention remains dynamic during the cutting process. The fabric itself is always kept taut due to traction. Furthermore, the method of the present invention can promptly send the cut fabric to the receiving table, and the negative pressure used for adsorbing the fabric is kept relatively stable, thereby overcoming the problems of fabric loosening and cutting misalignment caused by pressure relief in the prior art, which greatly improves the cutting quality.

[0021] Preferably, in step S50, the method of the present invention further includes:

[0022] During the cutting process, it is determined in real time whether the maximum distance of the current cutting pattern in the conveying direction is less than the preset cutting upper limit. If so, a continuous cutting command is sent to the multi-axis drive device; otherwise, a stop cutting command is sent to the multi-axis drive device.

[0023] Preferably, the method of the present invention further includes:

[0024] S500: The wear of the cutting head is monitored by a displacement pressure sensor or an acoustic sensor. If the wear exceeds the wear threshold, the cutting head is sharpened by a sharpening device.

[0025] S500 and S60 are executed independently without interfering with each other; when S500 is executing, S50 is temporarily interrupted.

[0026] Preferably, before S30, the method of the present invention further includes:

[0027] Set the origin of the coordinate system and define the conveying direction of the vacuum adsorption conveying mechanism as the positive X-axis direction.

[0028] Preferably, the pattern data to be cut also includes the outline range. If the fabric has multiple rows of pattern data to be cut along the vertical direction of the X-axis, then S30 is:

[0029] S31: Starting from the origin of the coordinate system, define the Y-axis based on the X-axis and the plane where the fabric is located;

[0030] S32: Define the Y-axis coordinates of the outline range of all pattern data to be cut, and obtain the Y-axis coordinates of the range;

[0031] S33: Based on the maximum distance in the conveying direction, the minimum distance in the conveying direction, and the range of Y-axis coordinates, calculate the position of each pattern to be cut on the fabric to obtain the cutting position data.

[0032] Secondly, the method of the present invention also provides a continuous cutting device for flexible fabrics, which adopts the above-mentioned method for continuous cutting of flexible fabrics, including a multi-thread control device, a vacuum adsorption conveying mechanism, a multi-axis cutting mechanism, a positioning device and a receiving table.

[0033] Among them, the multi-threaded control device is used to independently drive the vacuum adsorption conveying mechanism, the multi-axis cutting mechanism and the positioning device; the multi-threaded control device has a built-in first calculation module, a second calculation module and a sorting module;

[0034] The multi-axis cutting mechanism includes a multi-axis drive device and a cutting head disposed at the drive end of the multi-axis drive device; the vacuum adsorption conveying mechanism includes a conveyor belt and a vacuum adsorption platform disposed on the conveyor belt.

[0035] The first calculation module is used to acquire the fabric pattern data to be cut when the vacuum adsorption conveying mechanism adsorbs and starts conveying the fabric, and to calculate the maximum and minimum conveying distances in the conveying direction for each fabric pattern data.

[0036] The data of the pattern to be cut includes the cutting outline; the maximum distance in the conveying direction refers to the distance between the farthest end of the cutting outline from the vacuum adsorption platform outlet and the end of the vacuum adsorption platform; the minimum distance in the conveying direction refers to the distance between the nearest end of the cutting outline from the vacuum adsorption platform outlet and the end of the vacuum adsorption platform.

[0037] The second calculation module is used to calculate the position of each pattern to be cut on the fabric based on the maximum and minimum distances in the conveying direction, and to obtain the cutting position data.

[0038] The sorting module is used to sort each pattern to be cut according to the minimum distance in the conveying direction, and obtain the sorting result;

[0039] Among them, the pattern to be cut with the smaller minimum distance in the conveying direction is ranked earlier;

[0040] The multi-axis drive device is used to drive the cutting head to cut the fabric first at the position of the pattern to be cut with the smallest sorting result, based on the cutting position data and cutting outline.

[0041] The positioning device is used to monitor the fabric located on the vacuum adsorption conveying mechanism in real time. If the positioning device detects that the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result is greater than a preset threshold, it sends a command to the vacuum adsorption conveying mechanism to continue adsorbing and conveying the fabric; otherwise, the positioning device sends a stop conveying command to the vacuum adsorption conveying mechanism.

[0042] The receiving table is used to collect the cut fabric.

[0043] Preferably, it also includes a sharpening device for sharpening the cut head, the sharpening device being disposed at the drive end of the multi-axis drive device, and the multi-threaded control device being communicatively connected to the sharpening device.

[0044] Preferably, it also includes a displacement pressure sensor;

[0045] Among them, the displacement pressure sensor is used to monitor the wear of the cutter head;

[0046] The displacement pressure sensor is connected to the multi-threaded control device.

[0047] The present invention has at least the following advantages:

[0048] 1) Compared with the prior art, the fabric of the present invention maintains dynamics during the cutting process. The fabric itself remains taut due to the traction. Furthermore, the present invention can promptly send the cut fabric to the receiving table, and the negative pressure used to adsorb the fabric is kept relatively stable, thereby overcoming the problems of fabric loosening and cutting misalignment caused by pressure relief in the prior art. This greatly improves the cutting quality.

[0049] 2) Compared with the prior art, in order to address the problem of tool wear, the present invention sets up a sharpening interruption during the cutting process and uses a displacement pressure sensor or acoustic sensor to monitor the wear of the cutting head. If the wear is higher than the wear threshold, the present invention uses a sharpening device to sharpen the cutting head, so as to solve the problem of cutting head dulling in the prior art.

[0050] 3) Compared to existing technologies, the equipment of this invention is a high-precision fabric cutting machine tool that integrates a multi-threaded control device, a vacuum adsorption conveying mechanism, a multi-axis cutting mechanism, a positioning device, and a receiving table. This equipment can perform high-precision, high-efficiency, and high-safety cutting of fabrics. Attached Figure Description

[0058] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0060] This embodiment discloses a method and equipment for continuous cutting of flexible fabrics, which solves the problems existing in the prior art.

[0061] Example 1

[0062] like Figure 1 As shown, this embodiment discloses a method for continuously cutting flexible fabrics, the method comprising:

[0063] S10: Employs a multi-threaded control device to independently drive the vacuum adsorption conveying mechanism, the multi-axis cutting mechanism, and the positioning device.

[0064] In this embodiment, the aforementioned multi-threaded control device has a built-in multi-core processor, and its outer casing is equipped with a human-machine interface for human-machine interaction. The aforementioned vacuum adsorption conveying mechanism is an existing mechanism, comprising a conveyor belt, a vacuum adsorption platform mounted on the conveyor belt, and a vacuum exhaust silencer for vacuum suction; the flow channel of the vacuum adsorption platform is connected to the vacuum exhaust silencer. The multi-axis cutting mechanism is an existing mechanism, comprising a multi-axis drive device and a cutting head mounted on the drive end of the multi-axis drive device. The multi-axis drive device can be a three-axis drive arm, a four-axis drive arm, or a five-axis drive arm; the specific number of axes can be set according to actual conditions.

[0065] In this embodiment, the cutter head described in CN208414939U can be used.

[0066] Specifically, by configuring multi-threaded control devices to independently drive the vacuum adsorption conveying mechanism, multi-axis cutting mechanism, and positioning device, the latency of sequential execution logic is reduced, thereby improving the overall efficiency of the method itself.

[0067] S20: When the vacuum adsorption conveying mechanism adsorbs and starts conveying the fabric, acquire the fabric pattern data to be cut, and calculate the maximum and minimum conveying distances in the conveying direction for each pattern data to be cut.

[0068] In this embodiment, as Figure 2 As shown, the pattern data to be cut includes the cutting outline and the outline range. The cutting outline can be a regular outline or an irregular outline. The maximum distance in the conveying direction refers to the distance between the farthest endpoint of the cutting outline in the pattern data from the vacuum adsorption platform outlet and the end of the vacuum adsorption platform, i.e. Figure 2 The Xmax shown is used for conveying. The minimum distance in the conveying direction refers to the distance between the endpoint of the cutting contour in the pattern data that is closest to the vacuum adsorption platform outlet and the end of the vacuum adsorption platform. Figure 2 Xmin is shown.

[0069] S30: Calculate the position of each pattern to be cut on the fabric based on the maximum and minimum distances in the conveying direction, and obtain the cutting position data.

[0070] Prior to S30, the method of the present invention further includes:

[0071] Set the origin of the coordinate system and define the conveying direction of the vacuum adsorption conveying mechanism as the positive X-axis direction.

[0072] In this embodiment, only the case where there is a pattern data to be cut on the fabric along the vertical direction of the X-axis is considered. A one-dimensional coordinate system is set up before S30 to facilitate the determination of the cutting position data.

[0073] It should be noted that the cutting trajectory coordinates of the multi-axis cutting mechanism are different from the coordinate system described above. The coordinate data mentioned above is only used for sorting and judgment in subsequent steps. The coordinate origin can be set according to the actual situation.

[0074] S40: Sort each pattern to be cut according to the minimum distance in the conveying direction to obtain the sorting result.

[0075] In this embodiment, the pattern to be cut with the smallest minimum distance in the conveying direction is ranked earlier.

[0076] It should be noted that the sorting results obtained through S40 can be used to assist the multi-axis cutting mechanism in planning the cutting trajectory.

[0077] S50: Based on the cutting position data and cutting outline, a multi-axis drive device is used to drive the cutting head to prioritize cutting the fabric at the position of the pattern to be cut with the smallest sorting result.

[0078] Through the above S50, the cutting trajectory of the multi-axis cutting mechanism moves from the low-numbered pattern to the high-numbered pattern.

[0079] Furthermore, prior to the cutting in step S50 above, the method of the present invention further includes:

[0080] Is the number of patterns to be cut, n, greater than 0?

[0081] If so, obtain the pattern to be cut with the smallest sorting result;

[0082] If not, the end.

[0083] Furthermore, in step S50 above, the method of the present invention further includes:

[0084] During the cutting process, it is determined in real time whether the maximum distance Xmax of the current cutting pattern in the conveying direction is less than the preset cutting upper limit value XCmax. If so, a continuous cutting command is sent to the multi-axis drive device; otherwise, a stop cutting command is sent to the multi-axis drive device.

[0085] S60: The positioning device monitors the fabric on the vacuum adsorption conveying mechanism in real time. If the positioning device detects that the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result is greater than a preset threshold, it sends a command to the vacuum adsorption conveying mechanism to continue adsorbing and conveying the fabric; otherwise, the positioning device sends a stop conveying command to the vacuum adsorption conveying mechanism.

[0086] It should be noted that, as Figure 3 As shown, the pattern with the largest number in the above sorting results is the last pattern to be cut. When the last pattern to be cut is cut, it stays on the adsorption surface and waits for the cutting head to cut it.

[0087] S70: The cut fabric is removed from the vacuum adsorption conveyor and sent to the receiving table 5.

[0088] It should be noted that the above-mentioned cut fabric refers to the fabric before the last pattern to be cut. This fabric is automatically pushed into the receiving table by the force of the conveyor belt.

[0089] Unlike existing technologies, S50 and S60 in this invention are independent parallel processes. Fabric cutting is performed simultaneously during fabric conveying, improving cutting efficiency. The entire process requires no human assistance, enhancing fabric cutting safety. The fabric remains dynamic during cutting, maintaining tension due to traction. Furthermore, this invention allows for timely delivery of cut fabric to the receiving table 5, using negative pressure to maintain stability and overcome the problems of fabric slack and cutting misalignment caused by pressure release in existing technologies. This significantly improves cutting quality.

[0090] Preferably, the method of the present invention further includes:

[0091] S500: The wear of the cutting head is monitored by a displacement pressure sensor or an acoustic sensor. If the wear exceeds the wear threshold, the cutting head is sharpened by a sharpening device.

[0092] S500 and S60 are executed independently without interfering with each other; when S500 is executing, S50 is temporarily interrupted.

[0093] In one embodiment, the sharpening device described in CN104128850A may be used. In other embodiments, the sensor used to monitor the wear of the cutting head may also be a vibration sensor or an optical sensor.

[0094] Through the above technical solution, the method of the present invention sets a sharpening interruption subroutine during the cutting process. If the wear level is higher than the wear threshold, the cutting head is temporarily interrupted after the current cutting task is completed in S50, and the sharpening device is used to sharpen the cutting head. After the sharpening is completed, the process returns to S50. Compared with the prior art, the method of the present invention incorporates the function of automatic sharpening, which can solve the problem of cutting head dulling existing in the prior art.

[0095] Example 2

[0096] like Figure 4 As shown, this embodiment differs from Embodiment 1. If the fabric has multiple rows of patterns to be cut along the vertical direction of the X-axis, then S30 in Embodiment 1 is specifically as follows:

[0097] S31: Starting from the origin of the coordinate system, define the Y-axis based on the X-axis and the plane where the fabric is located;

[0098] S32: Define the Y-axis coordinates of the outline range of all pattern data to be cut, and obtain the Y-axis coordinates of the range;

[0099] S33: Based on the maximum distance in the conveying direction, the minimum distance in the conveying direction, and the range of Y-axis coordinates, calculate the position of each pattern to be cut on the fabric to obtain the cutting position data.

[0100] Correspondingly, the sorting of the patterns to be cut needs to take into account the minimum distance in the conveying direction, the origin of the coordinate system, and the cutting trajectory of the cutting head. However, in general, the principle of sorting the patterns with the smaller minimum distance in the conveying direction should be followed, with the patterns being sorted first.

[0101] Example 3

[0102] like Figure 5 As shown, this embodiment discloses a continuous cutting device for flexible fabrics, which adopts the continuous cutting method for flexible fabrics described in Embodiment 1 or 2. The device includes a multi-thread control device 1, a vacuum adsorption conveying mechanism 2, a multi-axis cutting mechanism, a positioning device 4, and a receiving table 5.

[0103] Among them, the multi-threaded control device 1 is used to independently drive the vacuum adsorption conveying mechanism 2, the multi-axis cutting mechanism 3 and the positioning device 4 respectively; the multi-threaded control device 1 has a built-in first calculation module, a second calculation module and a sorting module;

[0104] The multi-axis cutting mechanism 3 includes a multi-axis drive device and a cutting head disposed at the drive end 31 of the multi-axis drive device;

[0105] The first calculation module is used to acquire the fabric pattern data to be cut when the vacuum adsorption conveying mechanism 2 adsorbs and starts conveying the fabric, and to calculate the maximum and minimum conveying distances in the conveying direction for each fabric pattern data.

[0106] The pattern data to be cut includes the cutting outline;

[0107] The second calculation module is used to calculate the position of each pattern to be cut on the fabric based on the maximum and minimum distances in the conveying direction, and to obtain the cutting position data.

[0108] The sorting module is used to sort each pattern to be cut according to the minimum distance in the conveying direction, and obtain the sorting result;

[0109] Among them, the pattern to be cut with the smaller minimum distance in the conveying direction is ranked earlier;

[0110] The multi-axis drive device is used to drive the cutting head to cut the fabric first at the position of the pattern to be cut with the smallest sorting result, based on the cutting position data and cutting outline.

[0111] The positioning device 4 is used to monitor the fabric located on the vacuum adsorption conveying mechanism 2 in real time. If the positioning device 4 detects that the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result is greater than a preset threshold, it sends a command to the vacuum adsorption conveying mechanism 2 to continue adsorbing and conveying the fabric; otherwise, the positioning device 4 sends a stop conveying command to the vacuum adsorption conveying mechanism 2.

[0112] The receiving table 5 is used to collect the cut fabric.

[0113] Furthermore, the device of the present invention also includes a sharpening device for sharpening the cutting head. The sharpening device is disposed at the drive end 31 of the multi-axis drive device and is communicatively connected to the multi-thread control device 1. When the sharpening device receives the sharpening command issued by the multi-thread control device 1, the cutting head stops cutting and is in position, and then the cutting head is sharpened.

[0114] Furthermore, the aforementioned positioning device 4 can be an encoder used for position calculation during data acquisition.

[0115] Compared with existing technologies, the equipment of this invention integrates a high-precision fabric cutting machine tool with a multi-threaded control device 1, a vacuum adsorption conveying mechanism 2, a multi-axis cutting mechanism 3, a positioning device 4, and a receiving table 5, which can cut fabrics with high precision, high efficiency, and high safety.

[0116] Furthermore, the device of the present invention also includes a displacement pressure sensor, which is used to monitor the wear degree of the cutter head. The displacement pressure sensor is communicatively connected to the multi-threaded control device 1 to transmit the monitored wear degree of the cutter head to the multi-threaded control device 1 in real time.

[0117] Those skilled in the art will understand that all or part of the steps of the above embodiments can be implemented by hardware related to program instructions. The aforementioned program can be stored in a computer-readable storage medium. When the program is executed, it performs the steps of the above method embodiments. The aforementioned storage medium includes various media capable of storing program code, such as ROM, RAM, magnetic disk, or optical disk.

[0118] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.

If the positioning device (4) detects that the minimum distance of the conveying direction of the pattern to be cut with the largest sorting result is greater than a preset threshold, it sends a continuous adsorption and conveying instruction to the vacuum adsorption conveying mechanism (2); otherwise, the positioning device (4) sends a stop conveying instruction to the vacuum adsorption conveying mechanism (2). The receiving table (5) is used to collect the cut fabric; It also includes a sharpening device for sharpening the cutter head, the sharpening device being disposed at the drive end (31) of the multi-axis drive device, and the multi-threaded control device (1) being communicatively connected to the sharpening device; It also includes a displacement pressure sensor; wherein the displacement pressure sensor is used to monitor the wear of the cut head; the displacement pressure sensor is communicatively connected to the multi-threaded control device (1).
