Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment, and in particular to a folding device for special fabrics. Background Technology

[0002] With the continuous development of society, people no longer only require clothing to have basic functions; aesthetic appeal has also become an important criterion when choosing clothing, especially for women. Besides basic comfort, women also focus on the appearance of bras. Adding a layer of lace fabric to the cups enhances aesthetics. To match the shape of the cups, the lace is usually created by sewing together two pieces of lace with curved edges using darts or by forming a funnel shape that covers the cups. However, currently, to ensure symmetry and maintain beauty during the sewing of darts or curved edges... Traditionally, sewing involves manually folding and aligning the fabric before placing it on a sewing machine and pushing it along the edge. This method is not only labor-intensive but also inefficient. However, if a mechanical device is used to fold lace fabric for edge or dart sewing, the thin and soft nature of lace or similar special fabrics can cause edge deformation or folding during the folding process. Furthermore, the folded edges of lace or special fabrics are difficult to align perfectly like they are done manually. Therefore, designing a device that does not rely on manual labor, is more efficient for sewing lace fabric darts or edges, and can accurately align the edges of the sewing position has become an urgent problem to be solved.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] like Figure 1 As shown, this invention relates to a folding device for special fabrics, comprising a fixed plate 1, a folding plate 2, an axial flipping device 3, a connector 4, and a fabric fixing component 5. The fixed plate 1 is rotatably connected to the axial flipping device 3 via the connector 4, and the folding plate 2 is fixedly connected to the axial flipping device 3. The axial flipping device 3 has a hinge, which enables the fixed plate 1 and the folding plate 2 to rotate relative to each other. The fabric fixing component 5 is installed on the surface of the fixed plate 1 and the folding plate 2 facing the fabric. The fabric fixing component 5 includes an adsorption component 51, which is a negative pressure adsorption device, and the negative pressure adsorption direction is set in the same direction as the surface of the fixed plate 1 and the folding plate 2. The fixed plate 1 and the folding plate 2 are connected by an axial flipping device 3 and rotate around the axial flipping device 3 as an axis, forming a mechanism similar to a "hing". In use, the adsorption component 51 adsorbs the special fabrics on both sides symmetrically onto the surfaces of the fixed plate 1 and the folding plate 2 respectively. The axial flipping device 3 drives the folding plate 2 to rotate, causing the folding plate 2 to fold towards the fixed plate 1, achieving the purpose of symmetrical folding. After folding, the edges that need to be connected are then sewn together. This folding device eliminates the tedious sewing process and reduces the complexity of manual labor.

[0024] The axial flipping device 3 includes a rotation drive device 31, a base 32, and a folding member 33. The base 32 is hinged to the folding member 33 via a hinge, and the base 32 is connected to the fixed plate 1 via a connector 4. The folding member 33 is fixedly connected to the folding plate 2. The rotation drive device 31 is connected to the pivot at the hinge position of the folding plate 2 and drives the folding plate 2 to perform a positioning axial rotation along the pivot of the hinge, forming a flipping structure that allows the fixed plate 1 and the folding plate 2 to fold or unfold with each other. When the axial flipping device 3, which is similar to a hinge mechanism, is working, the rotation drive device 31 is connected to the folding part 33, which drives the folding part 33 to rotate. Here, the folding part 33 needs to be at the hinge position, with a part of its end exposed and fixedly connected to the rotating end of the rotation drive device 31. The rotation of the rotation drive device 31 drives the exposed part of the folding part 33 to rotate around the hinge connection position as the axis. In order to ensure that the rotation speed and the angle of a single rotation can be controlled, the rotation drive device 31 can be driven by a stepper motor to ensure the accuracy of the folding action during the folding process, ensure that the fabric does not run on the board during folding, and improve the stability of the folding work.

[0025] The connecting part 4 is a rotating connecting part, including a rotating motor 41 and an adapter block 42. The fixed end of the rotating motor 41 is fixedly connected to the fixed plate 1. The axial flipping device 3 is fixedly connected to the rotating end of the rotating motor 41 through the adapter block 42 and rotates together with the rotating motor. The rotating shaft of the rotating motor 41 and the flipping rotating shaft of the axial flipping device 3 are perpendicular to each other. After the fixed end of the rotating motor 41 is fixedly connected to the fixed plate 1, the position of the motor can be ensured to be fixed. The rotating end drives the axial flipping device 3 to rotate the folding plate 2 fixed to it. After the axial flipping device 3 drives the folding plate 2 to complete the folding action, the fixed plate 1 and the folding plate 2 will reciprocate in the same plane through the rotation of the rotating motor 41 and the rotating end through the axial flipping device 3. At this time, the fixed plate 1 and the folding plate 2 maintain a clearance fit and rotate relative to each other. At this time, the fabric in the folded state between the fixed plate 1 and the folding plate 2 can adjust the position of the fabric edge through the above action to finally achieve the effect of complete alignment of the fabric edge. It should be noted that during the above process, the fixed plate 1 and the folding plate 2 always hold the fabric they are in contact with in a gripping state through the suction member 51 to ensure that the fabric they are in contact with will not slip during the relative rotation of the fixed plate 1 and the folding plate 2. The lower and upper pieces of the fabric are respectively fixed relative to the fixed plate 1 and the folding plate 2 and move with them.

[0026] To ensure that the rotation of the rotary motor 41 only occurs after the folding is completed, a limit switch 34 is provided on the axial flipping device 3. The normally open contact of the limit switch 34 is connected to the folding member 33, and the folding member 33 drives the normally open contact to move. The limit switch 34 is also connected to the circuit of the rotary motor 41, controlling whether the circuit is connected or disconnected. By controlling the circuit connection state of the rotary motor 41 through the limit switch 34, the possibility of the rotary motor 41 rotating before the folding is completed can be avoided. If rotation occurs before the folding is completed, the fabric on the board cannot be completely overlapped, the edges are misaligned, and the yield rate is reduced.

[0027] The rotating motor 41 is a stepper motor. The stepper motor can ensure that the rotation angle can be controlled. Because the error of non-overlapping edges after the fabric is folded is relatively small, it is only necessary to rotate with a small angle. Using a stepper motor can ensure the accuracy of the rotation angle and improve the yield of the final product.

[0028] The suction element 51 is a needle-punched suction cup. Because the special fabric being folded is lace, woven mesh, or other mesh-like fabrics, using a needle-punched suction cup can improve the fixing effect of the suction element 51 on the fabric during the folding process, enhance the stability during the folding process, and ensure that the two pieces of fabric remain aligned after folding.

[0029] like Figure 3As shown, in order to further ensure the stability of the fabric position during the folding process, the fabric fixing component 5 also includes an adhesive component 52, which includes a tube shell 521, a telescopic component 522, a telescopic drive component 523, and an adhesive head 524. The tube shell 521 is a tubular structure. The telescopic component 2 can move along the length of the tube inside the tube shell 521. The telescopic drive component 3 is set inside the tube shell 521 and is fixedly connected to one end of the telescopic component 522. The telescopic drive component 3 drives the telescopic component 522 to make directional telescopic movements of protruding and retracting the tube opening inside the tube shell 521. The adhesive head 4 is an adhesive patch and is fixedly installed on the end face of the telescopic component 2. The tube shell 521 of the adhesive component 52 faces the fabric. The telescopic component 522, housed within the tube shell 521, extends out of the tube shell 521 under the drive of the telescopic drive component 523. The extension length ensures that the adhesive head 524 protrudes from the tube shell 521. The adhesive head 524, with its adhesive properties, can adhere to the lace fabric and hold it in a fixed position on the fixing plate 1 and the folding plate 2, achieving the effect of fixing the special fabric. Using this adhesive component 52 ensures that the lace fabric is not damaged, maximizing the product yield, and the adhesion... The 52 component, together with the adsorption component 51, secures the lace fabric, ensuring that the fabric does not shift during folding. After folding and reaching the set position, the telescopic drive component 523 is activated again, retracting the telescopic component 522 and the adhesive head 524 into the tube housing 521. At this time, the opening of the tube housing 521 will hold the fabric in place, and the part of the adhesive head 524 that is attached to the lace fabric will separate from the fabric because the fabric is held in place. At the same time, the adsorption component 51 also stops adsorbing the fabric, and they all stop working together to achieve the purpose of removing the fabric without damaging it.

[0030] Multiple adhesive pieces 52 are evenly installed on the surfaces of the fixing plate 1 and the folding plate 2, with at least one adhesive piece 52 at each edge of the fixing plate 1 and the folding plate 2. To ensure that the edges of the thin lace fabric do not deform or fold due to the speed of folding during the folding process, at least one adhesive piece 52 is installed at each corner of the fixing plate 1 and the folding plate 2 to adhere the edges of the fabric, ensuring that the fabric remains flat after folding and facilitating subsequent air-conditioning work.

[0031] like Figure 2As shown, even after folding, there will still be misalignment between the two pieces of fabric. Therefore, it also includes a visual alignment system 6. The visual alignment system includes a visual recognition system 61, a light source system 62, an information processing feedback system 63, and a workbench 64. The workbench 64 has a surface that can flatten the fixed plate 1 and the folding plate 2. The visual recognition system 61 and the light source system 62 are mounted on the workbench 64 and face the fixed plate 1 and the folding plate 2 on the surface. The visual recognition system 61 is signal-connected to the information processing feedback system 63. In use, the visual recognition system 61 takes pictures of the two pieces of fabric using a camera, and the information processing feedback system 63 analyzes and processes the pictures taken by the camera. The light source system 62 is used for supplementary lighting to ensure that the camera of the visual recognition system 61 can clearly capture the edge position of the fabric.

[0032] like Figure 4 and Figure 5 As shown, the information processing feedback system 63 includes a signal processor 631 and a signal receiver 632 and a processing operation signal transmitter 633 connected thereto. The signal receiver 632 is connected to the visual recognition system 61 to receive signals, and the processing operation signal transmitter 633 is connected to the signal receiver on the rotating motor 41 to send start and stop signals to make the rotating motor 41 rotate forward or backward. The signal processor 631 is used to process the image signals sent by the visual recognition system 61. In use, the photo captured by the visual recognition system 61 is transmitted to the signal processor 631 in the form of an image signal via the signal receiver 632. The signal processor 631 analyzes the image signal and determines the edge position of the fabric in the image signal. It also calculates the difference in position that will occur after the opposite folds are completed because they are not completely overlapped. Based on this difference, it calculates the corresponding rotation angle that will make the fabric completely overlap. This rotation angle is transmitted as a signal via the signal transmitter 633 to the signal receiver on the rotating motor 41. After receiving the signal, the signal receiver generates a corresponding pulse signal to control the rotation direction of the rotating motor and the required rotation time to control the rotation angle. This ensures that the edges of the two pieces of fabric are in an overlapping position before sewing, improving the product yield and ensuring the sewing quality.

[0033] First, during the material handling operation using the robotic arm, the robotic arm takes out the placed fabric from the set material handling point, and then moves a set distance to place the lace fabric on the folding plane of the device. After the material handling is completed by the parameters that have been set in advance and placed on the folding panel, the central axis of the fabric is aligned with the axial flipping device 3 of the device of the present invention. In this way, the axis during folding is the axis of symmetry of the fabric. However, even if the robotic arm can ensure accuracy, there will still be a positional deviation of about 1mm. Therefore, a visual recognition system is needed to cooperate with the rotating motor 41 in the present invention to correct the deviation after folding.

[0034] For regular, tightly woven fabrics, the above method can be used. For special fabrics, such as lace, the visual recognition system needs to use edge sampling for contour recognition during the cut piece acceptance step. This is because lace fabric has edge defects, and the openwork structure of lace may create edge defects. To solve the problem of this fabric being unrecognizable or having low accuracy after recognition, the points identified at the lace edge can be connected adjacently to obtain the contour line of the corrected fabric shape. If the shape and size of the fabric do not meet the standard, a backtracking operation is performed. This backtracking operation means removing the non-compliant fabric from the folding device, and the robotic arm repeats the action, placing a new piece of fabric for folding. By comparing the obtained data signal with the pre-recorded standard size data, it can be determined whether the size data from both sides of the fabric to the folding symmetry axis meets the standard. Here, the standard refers to the size information pre-recorded in the system, with the standard placement position. If there is a deviation in the length dimension from both sides to the central axis, such as a positive or negative difference between the fabric dimension on the fixed side or the folding side and the recorded standard dimension, a signal will be sent to the rotating motor 41 to "twist" and adjust the position of the fabric. After folding, the start and stop of the rotating motor 41 are controlled by the signal sent by the processing operation signal transmitter, causing the fabric on the folding device side to twist under the action. Generally speaking, the rotating motor 41 drives the folding plate on the flipping side to twist, and the amount of twisting is set according to the error range of the robot arm. The adjustment range is no more than ±1mm within the error range of the robot arm. The adjustment amount can be adapted according to the type of fabric. Under normal circumstances, the final twisting distance is generally controlled within ±2mm (defined as positive or negative by the rotating motor 41 driving the upper fabric in a clockwise or counterclockwise direction). After folding, a gap of 0.5-1mm is maintained between the fabrics gripped on the fixed plate 1 and the folding plate 2, thereby adjusting the distance between the fixed plate 1 and the folding plate 2 under different fabric thickness conditions.

[0035] A stable working environment is usually required when performing actions such as picking up, flipping, and unloading materials. A clean, windless, and sealed environment with constant temperature and humidity is ideal. This allows for the smooth completion of actions when flipping and moving materials at large intervals, with the error within the rated range.

[0036] However, the micro-gap between the fixed plate 1 and the folding plate 2 will cause errors outside the rated range during material handling, folding, and unloading. These errors originate from: the folding plate being very close to or in direct contact with the fabric during operation; and the adhesion caused by static electricity between the fabric and the equipment. After being gripped and released, the fabric is still prone to unintended displacement. Furthermore, if the fabric's elasticity is too high or it is easily deformed, this error will further increase. This can be resolved by installing a pneumatic vacuum breaking device, bringing the error back within the rated range. Specifically, a pneumatic vacuum breaking device is installed on the folding plate 2. This device consists of a blower and a blower pipe. A through hole is provided on the folding plate to connect to the blower pipe, and one end of the blower pipe... One end is connected to the through hole, and the other end is connected to the fan. The air blowing direction is towards the fabric. By turning on the fan, the flowing air can be blown onto the fabric gripped on the folding plate 2. The blowing surface is the contact surface between the fabric and the folding plate 2. After the pneumatic vacuum breaking device folds and twists the lace fabric, it blows air onto the folded lace fabric so that the upper layer of the double-layered lace fabric formed after folding can be pierced by the needles of the needle suction cups on the fixing plate 1, thereby achieving the function of fixing the relative position of the double-layered lace fabric. At this time, the folding plate 2 is folded back to the initial position. During this process, the fabric on top will not move or cause errors. Then, the double-layered fabric after folding can be used for subsequent edge sewing or dart sewing operations.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all embodiments here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
