Description

Technical Field

[0001] This invention relates to the field of garment equipment technology, and in particular to an automatic feeding device and its control method. Background Technology

[0002] In automated sewing technology, a pressure plate is typically used to hold the fabric in place before it is dragged along for sewing. However, in existing technologies, the fabric is prone to wrinkles or unevenness when placed on the sewing table, especially softer fabrics such as pure cotton. The edges of these fabrics are also prone to curling. Sewing in this condition can affect the sewing effect and the overall quality of the garment, making it difficult to guarantee processing efficiency and quality. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to solve the problem that fabrics are prone to wrinkles or curling in the prior art, which makes it impossible to guarantee processing efficiency and quality.

[0004] To address the aforementioned technical problems, this invention provides an automatic feeding device, comprising a feeding machine, a stacking machine, and a fabric gripping mechanism. The feeding machine includes a feeding tray and a feeding linear motion mechanism. The feeding tray is used to place stacked fabric, and the feeding linear motion mechanism is used to drive the feeding tray to move along a third direction. The stacking machine is provided with a stacking platform, and the fabric gripping mechanism is slidably disposed on the stacking platform. The fabric gripping mechanism includes a gripper bracket, a fabric gripper assembly, and a fan assembly. The gripper bracket is disposed on the stacking platform and can move along a first direction. The fabric gripper assembly is mounted on the gripper bracket and is used to grip the top layer of stacked fabric. The fan assembly is mounted on the gripper bracket or the fabric gripper assembly and is used to blow the fabric flat.

[0005] More preferably, the feeding machine further includes:

[0006] A separating slide bar, positioned directly above the feeding tray along a second direction, is used to separate the top layer of stacked fabric; and

[0007] A stripping linear motion mechanism is used to drive the separation slide bar to move along a first direction.

[0008] More preferably, the stacker further includes:

[0009] A first guide rail is disposed on the stacking platform along the first direction, and the gripper bracket is slidably disposed on the first guide rail; and

[0010] A drive mechanism is located at one end of the first guide rail and is used to drive the gripper bracket to move along the first direction.

[0011] More preferably, the gripper bracket includes:

[0012] The first bracket is slidably mounted on the first guide rail;

[0013] The second bracket is disposed on the first bracket, and the fabric gripper assembly is mounted on the second bracket.

[0014] More preferably, the first bracket is provided with a second guide rail extending in a second direction, and the second bracket is slidably mounted on the second guide rail.

[0015] More preferably, the fabric gripper assembly includes:

[0016] The fixed gripper assembly is fixedly mounted in the middle of the gripper bracket; and

[0017] An adjustable gripper assembly is movably mounted on the second bracket, and the adjustable gripper assembly is located on both sides of the fixed gripper assembly.

[0018] More preferably, the second bracket is provided with a third guide rail extending along a second direction, and the adjustable gripper assembly is slidably mounted on the third guide rail.

[0019] More preferably, the fan assembly includes:

[0020] Support rods are symmetrically arranged on the gripper bracket or the fabric gripper assembly; and

[0021] A fan is mounted on the support rod, and the fan's airflow direction is opposite to that of the fixed gripper assembly.

[0022] More preferably, the fabric gripper assembly includes:

[0023] A first connecting plate is connected to the gripper bracket, and a position sensor is provided on the first connecting plate;

[0024] The gripper body, located on the first connecting plate, is used to grip the fabric; and

[0025] The first pressing mechanism and the second pressing mechanism are both located on the first connecting plate and are used to press and pull the fabric.

[0026] The present invention also provides a control method based on the above-described automatic feeding device, the method comprising the following steps:

[0027] The stacked fabric is placed on the loading tray, the loading tray is raised, and the position of the stacked fabric in the third direction is determined by the position sensor.

[0028] The fabric is gripped by the fabric gripper assembly and moved to a designated position. The fabric is then blown flat by the fan assembly and pulled flat in the first direction by the first pressing mechanism and the second pressing mechanism.

[0029] The automatic feeding device and its control method provided by this invention have the following advantages compared with the prior art:

[0030] This invention utilizes a linear motion mechanism to move stacked fabric on a feeding tray in a third direction. Once the top layer of fabric reaches a designated height, a fabric gripper assembly picks it up from the stack and places it at a designated position on the stacking table. The fabric gripper assembly can press and pull the fabric to make it flat, and then a fan assembly blows the fabric flat, ensuring that the fabric is wrinkle-free and curl-free. This effectively avoids wrinkles or curling edges that could affect the sewing effect and the overall quality of the garment, reducing rework and improving processing efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] Example 1

[0050] like Figure 1 As shown, this embodiment provides an automatic feeding device, including a feeder 1, a stacker 2, and a fabric gripping mechanism 3. The feeder 1 is used to place stacked fabric 4, and the fabric gripping mechanism 3 is used to grip the top layer of the stacked fabric 4 and transfer it to the stacker 2 for processing. For ease of subsequent description and explanation, [the following is omitted as it is not part of the description]. Figure 1 The feeder 1 is defined as being located behind the stacker 2. That is, from the first direction X, the stacker 2 is in front and the feeder 1 is behind.

[0051] In the specific implementation method, please refer to Figures 1-3 The feeding machine 1 includes a feeding tray 11 and a feeding linear motion mechanism 14. The feeding tray 11 is used to place stacked fabric 4, and the feeding linear motion mechanism 14 is used to drive the feeding tray 11 to move along the third direction Z, so that the top layer of the stacked fabric 4 can reach a specified height so that the fabric gripping mechanism 3 can grip it. After gripping, the feeding linear motion mechanism 14 controls the feeding tray 11 to descend, so that the top layer of the stacked fabric 4 can be separated.

[0052] It should be noted that in the above embodiments, the third direction Z represents the height direction, that is, the feeding linear motion mechanism 14 can drive the stacked fabric 4 to rise or fall.

[0053] In some embodiments, to ensure that the top layer of fabric can be separated from the stacked fabric 4, the feeding machine 1 further includes a separating slide bar 13 and a peeling linear motion mechanism 12. The separating slide bar 13 is located directly above the feeding tray 11 along the second direction Y and is used to separate the top layer of fabric from the stacked fabric 4. The peeling linear motion mechanism 12 is used to drive the separating slide bar 13 to move along the first direction X. During the separation process, the peeling linear motion mechanism 12 drives the separating slide bar 13 to move along the first direction X, so that the separating slide bar 13 passes between the top layer of fabric and the stacked fabric 4 to ensure that the top layer of fabric is completely separated. At the same time, the separating slide bar 13 also serves to support the top layer of fabric.

[0054] In the above embodiment, it should be noted that the peeling linear motion mechanism 12 is initially located at one end of the feeder 1 near the stacker 2, so as to avoid the fabric gripping mechanism 3 gripping the top layer of fabric.

[0055] In some implementation methods, please refer to Figures 1-3The stacker 2 is provided with a stacking platform 21, and the fabric grabbing mechanism 3 is slidably disposed on the stacking platform 21. Further, the stacking platform 21 is provided with a first guide rail 22, which is disposed on the stacking platform 21 along the first direction X. One end of the first guide rail 22 is provided with a driving mechanism 23, which is used to drive the gripper bracket 31 to move along the first direction X. When the fabric grabbing mechanism 3 grabs the uppermost layer of fabric at the rear end, under the action of the driving mechanism 23, the fabric grabbing mechanism 3 moves towards the front end along the first direction X so as to transfer the fabric to the stacking platform 21.

[0056] like Figure 4 As shown, in some embodiments, the fabric gripping mechanism 3 includes a gripper bracket 31, a fabric gripper assembly 32, and a fan assembly 33. The gripper bracket 31 is disposed on the stacking platform 21 and can move along the first direction X, specifically disposed on the first guide rail 22. The fabric gripper assembly 32 is mounted on the gripper bracket 31 and is used to grip the top layer of the stacked fabric 4. The fan assembly 33 is mounted on the gripper bracket 31 or the fabric gripper assembly 32 and is used to blow the fabric flat.

[0057] In addition, in the above embodiments, at least two fabric gripper assemblies 32 are provided, and in this embodiment, three are preferred, which can not only ensure the stability of gripping, but also reduce the wrinkles and curling of the fabric during the transfer process.

[0058] In the above embodiment, the feeding linear motion mechanism 14 is used to move the stacked fabric 4 on the feeding tray 11 in the third direction Z. When the top layer of fabric reaches the specified height, the fabric gripper assembly 32 grabs the top layer of fabric from the stacked fabric 4 and places it on the specified position of the stacking table 21. The fabric gripper assembly 32 can drag the fabric to make it flat, and then the fan assembly 33 blows the fabric flat to ensure that the fabric is wrinkle-free and curled. This can effectively avoid wrinkles or curling that would affect the sewing effect and the overall quality of the garment, reduce rework, and improve processing efficiency.

[0059] In some embodiments, the gripper bracket 31 includes a first bracket 311 and a second bracket 312, wherein the first bracket 311 is slidably mounted on the first guide rail 22, the second bracket 312 is mounted on the first bracket 311, and the fabric gripper assembly 32 is mounted on the second bracket 312. In this embodiment, as shown... Figure 4 As shown, the second bracket 312 and the first bracket 311 are fixedly connected, meaning that the entire gripper bracket 31 can move along the first direction X on the first guide rail 22.

[0060] In some embodiments, the fabric gripper assembly 32 includes a fixed gripper assembly 32a and an adjustable gripper assembly 32b. The fixed gripper assembly 32a is fixedly mounted in the middle of the gripper bracket 31, and the adjustable gripper assembly 32b is movably mounted on the second bracket 312. The adjustable gripper assembly 32b is located on both sides of the fixed gripper assembly 32a. It should be understood that the fixed gripper assembly 32a and the adjustable gripper assembly 32b differ only in their installation methods, and their specific structural designs are the same or similar.

[0061] In the above embodiments, in order to ensure that fabrics of different sizes can be gripped, the distance or position between the fabric gripper assemblies 32 should be adjustable. In this embodiment, the second bracket 312 is provided with an adjustment groove 3121 along the second direction Y, so that the fabric gripper assemblies 32 can adjust the spacing or position along the adjustment groove 3121 to meet the gripping requirements of different fabrics.

[0062] It should be noted that the above method of adjusting the distance or position between the fabric gripper components 32 by adjusting the long groove 3121 is a manual method and still requires manual intervention for adjustment.

[0063] In another embodiment, such as Figure 5 As shown, in order to achieve automation and reduce the intensity of manual labor, a second guide rail 313 extending along the second direction Y is provided on the first bracket 311, and the second bracket 312 is slidably installed on the second guide rail 313. That is, the first bracket 311 can slide along the first direction X on the first guide rail 22, and the second bracket 312 can slide along the second direction Y on the second guide rail 313, thereby adjusting the position of the fabric gripper assembly 32 in the second direction Y.

[0064] More preferably, in order to adjust the distance between the adjustable gripper assembly 32b and the fixed gripper assembly 32a, a third guide rail 314 extending along the second direction Y is provided on the second bracket 312. The adjustable gripper assembly 32b is slidably mounted on the third guide rail 314, that is, the fabric gripper assembly 32 can move as a whole along the second direction Y, or the adjustable gripper assembly 32b can move alone along the second direction Y, so as to improve the gripping accuracy and stability of the fabric gripper assembly 32.

[0065] In the specific implementation method, please refer to Figure 6 and Figure 7 To understand this, the fabric gripper assembly 32 includes a first connecting plate 321, which is connected to the gripper bracket 31. The first connecting plate 321 is equipped with a position sensor 3210, which can detect and determine the position and height of the stacked fabric 4 in the third direction Z, thereby improving the gripping accuracy and effectiveness of the fabric gripper assembly 32 and avoiding phenomena such as missing the gripper.

[0066] In the above embodiments, a gripper body 323 is provided below the first connecting plate 321. In the actual process of gripping the fabric, it is the gripper body 323 that grips the fabric. In other embodiments, in order to ensure that the gripper body 323 can return to its original position after gripping the fabric, a second connecting plate 322 is also provided below the first connecting plate 321. The gripper body 323 is installed at the bottom of the second connecting plate 322. A spring and a limiting pin are provided between the second connecting plate 322 and the first connecting plate 321. The limiting pin ensures that the second connecting plate 322 always moves along the third direction Z, while the spring can reset the gripper body 323 to its initial state, so as to avoid affecting the subsequent gripping of the fabric and improve the gripping efficiency.

[0067] In some embodiments, after grasping the fabric, it is necessary to adjust the position of the fabric and press it. Therefore, the fabric gripper assembly 32 also includes a first pressing mechanism 32c and a second pressing mechanism 32d. The first pressing mechanism 32c and the second pressing mechanism 32d are both located on the first connecting plate 321 and are used to press and pull the fabric.

[0068] In the above embodiments, continue to refer to Figure 6 and Figure 7 The first pressing mechanism 32c includes a first pressing cylinder 324 and a third connecting plate 325. The first pressing cylinder 324 is fixed to the side wall of the first connecting plate 321, and the third connecting plate 325 is disposed at the piston end of the first pressing cylinder 324. Preferably, the third connecting plate 325 is arranged parallel to the stacking platform 21. When the piston end of the first pressing cylinder 324 extends, the third connecting plate 325 presses down to press the fabric onto the stacking platform 21.

[0069] It should be noted that the third connecting plate 325 should not interfere with the movement of the gripper body 323.

[0070] In the above example, to prevent the third connecting plate 325 from damaging the fabric during the pressing process, the first pressing mechanism 32c also includes a first pressing plate 326 located at the bottom of the third connecting plate 325. The connection between the first pressing plate 326 and the third connecting plate 325 is similar to the connection between the second connecting plate 322 and the first connecting plate 321. A spring and a limiting pin are provided between the first pressing plate 326 and the third connecting plate 325. The limiting pin ensures that the first pressing plate 326 always moves along the third direction Z, while the spring can reset the first pressing plate 326 to its initial state, avoiding affecting the subsequent gripping and pressing of the fabric and improving processing efficiency.

[0071] In another embodiment, such as Figure 8As shown, in order to avoid damage to the first pressing cylinder 324 and resulting in imbalance of the third connecting plate 325, two first pressing cylinders 324 are provided. Regarding the first connecting plate 321, a through hole is provided between the third connecting plate 325 and the first pressing plate 326 for the gripper body 323 to pass through, so as to avoid interference in operation.

[0072] Please continue to refer to Figure 6 and Figure 7 The second pressing mechanism 32d is located at the rear end of the first pressing mechanism 32c, and there is no interference between the two. Specifically, the second pressing mechanism 32d includes a second pressing cylinder 327 and a fourth connecting plate 328. The second pressing cylinder 327 is fixed to the side wall of the first connecting plate 321, and the fourth connecting plate 328 is located at the piston end of the second pressing cylinder 327. Preferably, the fourth connecting plate 328 is arranged parallel to the stacking platform 21. When the piston end of the second pressing cylinder 327 extends, the fourth connecting plate 328 presses down to press the fabric onto the stacking platform 21.

[0073] In the above example, to prevent the fourth connecting plate 328 from damaging the fabric during the pressing process, the first pressing mechanism 32c also includes a second pressing plate 329 located at the bottom of the fourth connecting plate 328. The connection between the second pressing plate 329 and the fourth connecting plate 328 is similar to the connection between the second connecting plate 322 and the first connecting plate 321. A spring and a limiting pin are also provided between the second pressing plate 329 and the fourth connecting plate 328. The limiting pin ensures that the second pressing plate 329 always moves along the third direction Z, while the spring can reset the second pressing plate 329 to its initial state, avoiding affecting the subsequent gripping and pressing of the fabric and improving processing efficiency.

[0074] In other embodiments, soft pads may be provided at the bottom of the first pressure plate 326 and the second pressure plate 329 to further protect the fabric while ensuring the pressing effect.

[0075] In some embodiments, the fan assembly 33 includes a support rod 331 and a fan 332. The support rod 331 is symmetrically arranged on the gripper bracket 31 or on the fabric gripper assembly 32. The fan 332 is arranged on the support rod 331, and the airflow direction of the fan 332 is away from the fixed gripper assembly 32a, so as to blow the fabric placed on the stacking table 21 flat, ensuring that the fabric is wrinkle-free and curled. This can effectively avoid wrinkles or curling that affect the sewing effect and the overall quality of the garment, reduce rework, and improve processing efficiency.

[0076] Example 2

[0077] This embodiment provides a control method based on the automatic feeding device of Embodiment 1, comprising the following steps:

[0078] Step 1: Place the stacked fabric 4 on the loading tray 11, lift the loading tray 11, and determine the position of the stacked fabric 4 in the third direction Z according to the position sensor 3210;

[0079] Step 2: Use the fabric gripper assembly 32 to grab the fabric and move it to the designated position, use the fan assembly 33 to blow the fabric flat, and use the first pressing mechanism 32c and the second pressing mechanism 32d to pull the fabric flat in the first direction X.

[0080] The control method in this embodiment can ensure that the fabric is wrinkle-free and curl-free, effectively avoiding wrinkles or curling that would affect the sewing effect and the overall quality of the garment, reducing rework and improving processing efficiency.

[0081] like Figure 1-9 As shown, at the beginning, the fabric gripping mechanism 3 is located above the feeder 1 (initial position), and controls the feeding linear motion mechanism 14 to lift the height of the stacked fabric 4 placed on the feeding tray 11 until the position sensor 3210 is triggered and the lifting stops. At this time, the top layer of the stacked fabric 4 reaches the specified height.

[0082] The gripper body 323 in the three fabric gripper assemblies 32 is controlled to grip the top layer of fabric. After gripping, the feeding linear motion mechanism 14 is controlled to lower the height of the stacked fabric placed on the feeding tray 11. The fabric gripping mechanism 3 moves forward to the designated position so that the last top layer of fabric is completely separated from the stacked fabric 4. At the same time, the separation slide bar 13 passes under the top layer of fabric under the drive of the peeling linear motion mechanism 12 to ensure that the top layer of fabric is completely separated and to support the top layer of fabric. (It should be noted that the peeling linear motion mechanism 12 is initially located at the end of the feeder 1 near the stacker 2 to avoid the fabric gripping mechanism 3 gripping the stacked fabric.)

[0083] The control drive mechanism 23 drives the fabric gripping mechanism 3 to move forward along the first guide rail 22. At the same time, the peeling linear motion mechanism 12 controls the separation slide bar 13 to move back synchronously until the starting position. After the fabric gripping mechanism 3 reaches the designated position, the gripper body 323 in the fabric gripper assembly 32 controls the fabric to be released and placed on the stacking platform 21.

[0084] The control drive mechanism 23 drives the fabric gripping mechanism 3 to move back a distance along the first guide rail 22, and positions the fabric gripping mechanism 3 above the fabric. The control first pressing cylinder 324 causes the first pressing plate 326 to move downward and press down on the fabric. The control drive mechanism 23 drives the fabric gripping mechanism 3 to move forward a distance, causing the lower hem of the fabric to slide down to the front of the stacking platform 21 (i.e., allowing the front end of the fabric to be suspended under its own weight). The lower hem of the fabric will be flattened under its own weight. The control drive mechanism 23 drives the fabric gripping mechanism 3 to move back a distance, so that the fabric is completely placed on the stacking platform 21 (during this movement, the edge of the front end of the fabric will be further flattened under the action of the turning angle of the stacking platform). Then the first pressing cylinder 324 pressing down on the fabric is retracted.

[0085] The control drive mechanism 23 drives the fabric gripping mechanism 3 to move forward a certain distance, so that the first pressure plate 326 is above the lower edge of the fabric and does not exceed the edge of the fabric. At this time, the control second pressure cylinder 327 extends, the second pressure plate 329 moves downward and presses the fabric, and then the control drive mechanism 23 drives the fabric gripping mechanism 3 to push the fabric back to the edge of the stacking platform 21, so that one end of the fabric collar hangs down to the stacking platform 21 and is flattened under the action of gravity.

[0086] The first pressing cylinder 324 is extended, and the first pressing plate 326 presses down on the fabric. Then, the second pressing cylinder 327 is retracted, and the four fans 332 are activated to blow air to the left front, left rear, right front, and right rear (i.e., the four corners of the fabric). At the same time, the drive mechanism 23 is controlled to move the fabric gripping mechanism 3 forward a certain distance, so that the fabric is placed in the required position. In this way, the fabric that is easy to roll up at the front and back ends can be pulled flat. During the process of dragging the fabric forward and backward, the wrinkles on the fabric will also be pulled forward and backward to flatten them, achieving a wrinkle removal effect.

[0087] Finally, control the first pressing cylinder 324 to retract, and continue to keep the fan 332 blowing air for a period of time before stopping, so that the edge of the fabric is flat.

[0088] The control drive mechanism 23 drives the fabric gripping mechanism 3 back to the initial position to prepare for the next feeding.

[0089] In summary, the present invention provides an automatic feeding device and its control method, which utilizes a feeding linear motion mechanism 14 to move the stacked fabric 4 on the feeding tray 11 in the third direction Z. When the top layer of fabric reaches a specified height, the fabric gripper assembly 32 grabs the top layer of fabric from the stacked fabric 4 and places it on the designated position of the stacking table 21. The fabric gripper assembly 32 can drag the fabric to make it flat, and then the fan assembly 33 blows the fabric flat to ensure that the fabric is wrinkle-free and curl-free. This effectively avoids wrinkles or curling edges that affect the sewing effect and the overall quality of the garment, reduces rework, and improves processing efficiency.
