Description

Technical Field

[0001] The utility model relates to the technical field of cut piece separation, in particular to an automatic cut piece separation device. Background Art

[0002] At present, although automation technology has been popularized in many fields, the garment manufacturing industry still widely relies on manual sewing, mainly because most of the existing automated sewing equipment still requires manual feeding, resulting in limited production efficiency and increased costs. The key obstacle to the future development of unmanned automated sewing equipment lies in the lack of automatic cut piece separation technology, which is a prerequisite for realizing a fully automated process. The cut piece separation technology refers to automatically grasping the stacked cut pieces one by one from top to bottom in a single layer. The cut piece separation technology is often applied to automated and unmanned garment production equipment and workstations as the feeding module therein.

[0003] At present, for cut piece separation, mainly the vacuum adsorption method or the mechanical grasping method is adopted. Specifically, the cut piece separation structure generally controls a lifting mechanism and a gripper for grasping the cut pieces, and uses the lifting mechanism (such as an electric cylinder or a cylinder) to drive the gripper for grasping the cut pieces (such as a vacuum chuck that can generate negative pressure) to move up and down. After the gripper grasps the cut pieces, the lifting mechanism drives the gripper to rise, so as to suck up a layer of cut pieces; then the manipulator grasps the sucked-up cut pieces and moves the cut pieces to the target position. The existing cut piece separation structure has the following deficiencies. Since the cut piece fabric is soft, after the lifting mechanism drives the gripper and the cut pieces to rise, the edges of the cut pieces will droop downward and are distributed in a downward state. This makes it difficult for the jaws of the subsequent manipulator to smoothly enter the separated cut pieces (i.e., the cut pieces on the gripper) when approaching. When the edges of the cut pieces enter the jaws, they will bend and fold, and it is difficult to enter the jaws straight (failure to grasp straight), and it is easy to have the edges of the cut pieces folded in the jaws of the manipulator, resulting in problems such as folding marks and hemming of the cut pieces.

[0004] On the other hand, although the current grasping method can achieve the grasping of a single layer of cloth, the utility model person found in the actual application process that during the cut piece separation process, due to problems such as entanglement and adhesion of the cut piece fibers, it is easy to bring up one or more layers of the underlying cut pieces, especially on one side of the cut piece far from the gripper, it is more likely to bring up one or more layers of the underlying cut pieces, resulting in wrinkles, arching, and misalignment of the cut pieces from the designated position, and leading to failure of subsequent cut piece grasping and separation, and the problem of empty grasping. Summary of the Utility Model

[0005] The first object of the utility model is to provide an automatic cut piece separation device that can not only smoothly separate the cut pieces, but also is conducive to the jaws of the subsequent manipulator to grasp the separated cut pieces, effectively avoiding the problem that the edges of the cut pieces are folded in the jaws of the manipulator, resulting in folding marks and hemming of the cut pieces.

[0006] The second object of the present utility model is to provide an automatic cutting piece separation device that can effectively solve the problem in the prior art that when separating cutting pieces, it is easy to stick and lift one or more lower layers of cutting pieces, causing the cutting pieces to wrinkle, arch, and deviate from the designated position, resulting in the failure of subsequent grasping and separation of the cutting pieces.

[0007] The technical solution of the present utility model is as follows:

[0008] An automatic cutting piece separation system, characterized by comprising:

[0009] A cutting piece placement table, on which cutting pieces are stacked and placed;

[0010] One or more cloth pressing mechanisms, which include a cloth pressing assembly. The cloth pressing assembly includes a cloth pressing roller, and the cloth pressing roller presses on the stacked cutting pieces;

[0011] A lifting mechanism, including a lifting seat, and the lifting mechanism drives the lifting seat to move up and down;

[0012] A longitudinal translation mechanism, which drives the lifting mechanism to translate in the front-back direction of the cutting piece placement table;

[0013] A cutting piece single-layer separation mechanism arranged on the lifting seat, which includes a mounting seat arranged on the lifting seat, a flipping seat rotatably arranged on the mounting seat, and a flipping driving mechanism for driving the flipping seat to flip in the up-down direction. A gripper for grasping the cutting piece is arranged on the flipping seat.

[0014] When the gripper grasps the cutting piece, the cloth pressing rollers of all the cloth pressing mechanisms in the front-back direction of the cutting piece placement table are located behind the gripper. The specific operation of the automatic cutting piece separation system of this solution is as follows.

[0015] The flipping driving mechanism drives the flipping seat to rotate so that the grippers are distributed downward;

[0016] The lifting mechanism drives the gripper to descend to the designated position. At this time, the gripper adheres to the edge position of the uppermost cutting piece in the stacked cutting pieces, and the uppermost cutting piece is grasped by the gripper;

[0017] Then, the lifting mechanism drives the gripper to move up to the designated position; the longitudinal translation mechanism drives the lifting mechanism and the gripper to translate backward by a set distance L;

[0018] Next, the flipping drive mechanism drives the flipping seat to rotate, thereby driving the gripper to flip forward and upward by a set angle (generally 90 degrees upward), so that a part of the edge of the cut piece grabbed by the gripper is distributed forward, upward, or obliquely upward; in this way, this part of the cut piece edge that is forward, upward, or obliquely upward can enter the jaws of the manipulator straight, effectively avoiding the problem that when the edge of the cut piece enters the jaws, it will bend and fold, making it difficult to enter the jaws straight, and easily causing the edge of the cut piece to fold in the jaws of the manipulator, resulting in folding marks and hemming phenomena on the cut piece. At the same time, the separation of single-layer cut pieces is smoothly achieved.

[0019] On the other hand, during the process of separating the cut pieces (grabbing and separating the topmost cut piece), on the one hand, the cut pieces in the stacked state will be pressed by the cloth pressing rollers, effectively preventing the underlying single layer or multiple layers of cut pieces from being adhered and lifted, thereby avoiding wrinkles, arching, and misalignment of the cut pieces from the designated position, which may lead to failure in subsequent grabbing and separating of the cut pieces; on the other hand, the cloth pressing rollers can roll, thus ensuring that the topmost cut piece can be smoothly grabbed and separated, avoiding the problem that the excessive frictional force during the cut piece separation process affects the cut piece separation.

[0020] Preferably, it further includes a lateral translation mechanism, which includes a transverse sliding seat. The longitudinal translation mechanism drives the lateral translation mechanism to translate along the front-back direction of the cut piece placement table, and the lifting mechanism is arranged on the transverse sliding seat. The lateral translation mechanism drives the transverse sliding seat and the lifting mechanism to translate along the left-right direction of the cut piece placement table. In this way, the lateral translation mechanism can drive the transverse sliding seat and the lifting mechanism to translate, thereby driving the single-layer cut piece separation mechanism to move to the designated position, so as to meet the needs of different grabbing parts of different cut pieces and improve the adaptability of the automatic cut piece separation system.

[0021] Preferably, the cloth pressing mechanism is distributed above the rear part and / or the middle part of the cut piece placement table.

[0022] Preferably, it further includes a manipulator for grabbing the cut piece, and the manipulator includes jaws for grabbing the cut piece. After the flipping drive mechanism drives the flipping seat to rotate, thereby driving the gripper to flip forward and upward by a set angle (generally 90 degrees upward), so that a part of the edge of the cut piece grabbed by the gripper is distributed forward, upward, or obliquely upward, the manipulator moves the jaws, enabling this part of the cut piece edge that is forward, upward, or obliquely upward to enter the jaws of the manipulator straight. Then, the jaws clamp the cut piece and move it forward, thereby realizing the single-layer separation of the cut piece.

[0023] Preferably, the flipping drive mechanism includes:

[0024] A moving block;

[0025] A connecting rod, one end of which is hinged to the moving block and the other end of which is hinged to the flipping seat;

[0026] The driving actuator drives the moving block to move and drives the flipping seat to flip in the up and down directions through a connecting rod. In this way, the driving actuator can drive the moving block to move, so as to drive the flipping seat to flip up or down through the connecting rod.

[0027] Preferably, the flipping driving mechanism is a motor. In this way, the flipping seat can be directly driven by the motor to flip up or down, and its structure is simple and easy to manufacture.

[0028] Preferably, the gripper is a needle-punching suction cup or a vacuum suction cup, and the needle-punching suction cup includes a plurality of needles. The advantages of using a needle-punching suction cup to grasp the cut pieces are as follows: the needle-punching stroke is adjustable to adapt to different fabric thicknesses, the fixture has good versatility; the grasping force is large, and it can effectively overcome the adhesion phenomena such as fiber entanglement; there are no requirements for the elasticity, air permeability, material, and weaving method of the fabric, and the adaptability is good. The advantages of using a vacuum suction cup to grasp the cut pieces are as follows: the suction cup is in flexible contact with the fabric and is not easy to damage the fabric, and it is simple and easy to use with low cost.

[0029] Preferably, the cloth pressing mechanism includes a cloth pressing driving mechanism and a mounting part, the cloth pressing assembly is arranged on the mounting part, the cloth pressing driving mechanism drives the mounting part to move up and down, and the cloth pressing assembly further includes:

[0030] A guiding member, which is slidably connected to the mounting part in the up and down directions, and the cloth pressing roller is rotatably arranged at the bottom of the guiding member;

[0031] An elastic element, which provides an elastic force to drive the guiding member and the cloth pressing roller to move downward, so that the cloth pressing roller presses on the stacked cut pieces. The specific working process of the cloth pressing mechanism is as follows: the driving actuator drives the mounting part and the cloth pressing assembly to move downward by a specified distance, so that the cloth pressing roller presses on the stacked cut pieces and compresses the elastic element. In this way, the pressure exerted by the cloth pressing roller on the cut pieces will be provided by the elastic element; thus, during the process of separating the cut pieces (the topmost cut piece is grasped and separated), on the one hand, the stacked cut pieces will be pressed by the cloth pressing roller, effectively avoiding sticking and lifting one or more layers of cut pieces below, thereby avoiding wrinkles, arching, and misalignment of the cut pieces from the specified position, which may lead to failure in grasping and separating the subsequent cut pieces; on the other hand, the pressure exerted by the cloth pressing roller on the cut pieces is provided by the elastic element, which can avoid the problem that the pressure exerted by the cloth pressing roller on the cut pieces is too large and affects the separation of the cut pieces.

[0032] Preferably, the single-layer cut piece separating mechanism is one or more, and the gripper in the same single-layer cut piece separating mechanism is one or more.

[0033] Preferably, it further includes a frame, the top of the frame is located above the cut piece placing table, the longitudinal translation mechanism is arranged on the frame and is located above the cut piece placing table, the lifting mechanism and the lifting seat are located above the cut piece placing table, and the single-layer cut piece separating mechanism is located above the cut piece placing table.

[0034] The beneficial effects of the present utility model are as follows:

[0035] Firstly, it can not only smoothly separate the cut pieces, but also facilitate the subsequent gripper of the manipulator to grasp the separated cut pieces, effectively avoiding the problem that the edges of the cut pieces are folded inside the gripper of the manipulator, resulting in folding indentations and hemming phenomena on the cut pieces.

[0036] Secondly, it can effectively solve the problem in the prior art that during the separation process of the cut pieces, one or more layers of cut pieces below are easily adhered and lifted, causing the cut pieces to wrinkle and arch away from the designated position, resulting in the failure of subsequent grasping and separation of the cut pieces.

[0052] Cut piece 9. Specific implementation mode

[0053] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation modes:

[0054] Specific embodiment 1, as Figures 1-6 shown, an automatic cut piece separation system, characterized in that it includes a frame 2, a cut piece placement table 1, a cloth pressing mechanism 3, a cut piece single-layer separation mechanism 4, a lifting mechanism 5 and a longitudinal translation mechanism 6. The cut pieces 9 are stacked on the cut piece placement table 1.

[0055] In one implementation mode, as Figure 1 , Figure 2 shown, the frame 2 is directly fixedly arranged on the table top of the cut piece placement table 1.

[0056] In another implementation mode, the frame 2 and the cut piece placement table 1 are respectively supported on a support surface (for example, the frame 2 and the cut piece placement table 1 are respectively supported on the floor or the ground). The top of the frame 2 is located above the cut piece placement table 1. The frame 2 and the cut piece placement table 1 can be connected through a connecting piece, or can be independent of each other without connection.

[0057] The cloth pressing mechanism 3 is one or more. In this embodiment, the cloth pressing mechanism 3 is multiple. The cloth pressing mechanism 3 is arranged on the frame 2 and is located above the cut piece placement table 1, and each cloth pressing mechanism 3 is distributed at the rear part and / or the middle part of the cut piece placement table 1. The cloth pressing mechanism 3 includes a cloth pressing component 3.4. The cloth pressing component 3.4 includes a cloth pressing mechanism. The cloth pressing mechanism includes a rotatably arranged cloth pressing roller 3.4.1. The cloth pressing roller 3.4.1 presses on the stacked cut pieces.

[0058] The longitudinal translation mechanism 6 is arranged on the frame 2 and is located above the cut piece placement table 1. The longitudinal translation mechanism 6 drives the lifting mechanism 5 to translate in the front-back direction of the cut piece placement table 1.

[0059] The lifting mechanism 5 includes a lifting seat 5.1. The lifting mechanism 5 and the lifting seat 5.1 are located above the cut piece placement table 1. The lifting mechanism 5 drives the lifting seat 5.1 to move up and down. The cut piece single-layer separation mechanism 4 is arranged on the lifting seat 5.1. The cut piece single-layer separation mechanism 4 is located above the cut piece placement table 1.

[0060] In one embodiment, as Figures 1-3 shown, there is one single-layer separating mechanism 4 for cut pieces. By using one single-layer separating mechanism 4 to grasp the cut pieces, the structure is simple and the manufacturing cost can be reduced.

[0061] In another embodiment, as Figure 4 shown, there are multiple single-layer separating mechanisms 4 for cut pieces. For example, there are two or three or four or more single-layer separating mechanisms 4 for cut pieces ( Figure 4 in the figure, there are two single-layer separating mechanisms for cut pieces).

[0062] In one example, multiple single-layer separating mechanisms 4 are arranged side by side. The number of single-layer separating mechanisms 4 for cut pieces can be arranged according to actual needs. Multiple single-layer separating mechanisms 4 can achieve a better grasping effect and are beneficial to applications in cases where the area of the cut piece is large or the shape of the cut piece is complex.

[0063] In another example, multiple single-layer separating mechanisms 4 are arranged staggeredly. The number of single-layer separating mechanisms 4 for cut pieces can be arranged according to actual needs. Multiple single-layer separating mechanisms 4 can achieve a better grasping effect and are beneficial to applications in cases where the area of the cut piece is large or the shape of the cut piece is complex.

[0064] The single-layer separating mechanism 4 for cut pieces includes a mounting seat 4.1 arranged on the lifting seat 5.1, a flipping seat 4.3 rotatably arranged on the mounting seat 4.1, and a flipping driving mechanism 4.2 for driving the flipping seat 4.3 to rotate. The mounting seat 4.1 is arranged on the lifting seat 5.1. In this embodiment, the mounting seat 4.1 is mounted on the lifting seat 5.1 by bolts. In this way, it is convenient to install the mounting seat 4.1. The flipping seat 4.3 flips in the up and down direction. Specifically, the flipping seat 4.3 is rotatably arranged on the mounting seat 4.1 through a rotating shaft 4.4. The rotating shaft 4.4 is horizontally distributed and extends along the left-right direction of the cut piece placing table 1.

[0065] The flipping driving mechanism 4.2 is arranged on the mounting seat 4.1. Specifically,

[0066] In one implementation of this embodiment, as Figure 1 、 Figure 5As shown, the flipping drive mechanism 4.2 includes a moving block 4.22, a connecting rod 4.23, and a driving actuator 4.21. One end of the connecting rod 4.23 is hinged to the moving block 4.22, and the other end of the connecting rod 4.23 is hinged to the flipping seat 4.3. The driving actuator 4.21 is arranged on the mounting seat 4.1. The driving actuator 4.21 drives the moving block 4.22 to move. During the process that the driving actuator 4.21 drives the moving block 4.22 to move, the flipping seat 4.3 is driven to flip upward or downward by the connecting rod 4.23 (i.e., the flipping seat 4.3 is driven to flip along the up-and-down direction by the connecting rod 4.23). Specifically, when the driving actuator 4.21 drives the moving block 4.22 to move along the up-and-down direction, the moving block 4.22 drives the flipping seat 4.3 to flip upward or downward through the connecting rod 4.23.

[0067] The driving actuator 4.21 is a cylinder or an electric cylinder. The telescopic rod of the cylinder or the electric cylinder is fixedly connected to the moving block 4.22. Of course, it should be noted that the driving actuator 4.21 can also be other mechanisms in the prior art, such as an electric push rod, etc. In this embodiment, the driving actuator 4.21 is an electric cylinder. In this way, not only can the flipping seat 4.3 be driven to flip upward or downward by the electric cylinder drive, but also the flipping angle of the flipping seat 4.3 to flip upward or downward can be set as required. For example, during or after the upward movement of the gripper 4.6, the electric cylinder can control the moving distance of the moving block 4.22 to control the upward flipping angle of the flipping seat 4.3, so that a part of the edge of the cut piece grabbed by the gripper 4.6 faces forward or upward or obliquely upward.

[0068] In another implementation manner of this embodiment, the flipping drive mechanism 4.2 is a motor (not shown in the figure). In this way, the flipping seat 4.3 can be directly driven to flip upward or downward by the motor, and its structure is simple and easy to manufacture.

[0069] As Figures 1-5 shown, a gripper 4.6 for grabbing the cut piece is provided on the flipping seat 4.3. The gripper 4.6 can adopt the following methods.

[0070] In one implementation manner of this embodiment, the gripper 4.6 is a needle-piercing suction cup, which includes a plurality of inserting needles. The flipping drive mechanism 4.2 drives the flipping seat 4.3 to flip along the up-and-down direction, so that the inserting needles of the needle-piercing suction cup are distributed downward or forward (forward means facing the front of the cut piece placement table 1). Using the needle-piercing suction cup to grab the cut piece has the following advantages: the needle-piercing stroke is adjustable to adapt to different fabric thicknesses, the fixture has good versatility; the grabbing force is large, and it can effectively overcome the adhesion phenomenon such as fiber entanglement; there are no requirements for the elasticity, air permeability, material, and knitting method of the fabric, and the adaptability is good.

[0071] In another implementation of this embodiment, the gripper 4.6 is a vacuum suction cup. The flipping drive mechanism 4.2 drives the flipping base 4.3 to flip in the up and down direction, so that the vacuum suction cups are distributed downward or forward (forward means facing the front of the piece placement table 1). Grabbing the piece with a vacuum suction cup has the following advantages: the suction cup has a flexible contact with the fabric, which is not easy to damage the fabric, and it is simple, easy to use and low in cost.

[0072] Of course, it should be noted that the gripper 4.6 can also be other grasping structures in the prior art. For example, an electrostatic adsorption device, etc. The electrostatic adsorption device uses the principle of electrostatic adsorption to adsorb the fabric.

[0073] When the gripper 4.6 grabs the piece, all the pressing rollers 3.4.1 of the pressing mechanism 3 are located behind the gripper 4.6 in the front and back direction of the piece placement table 1.

[0074] The specific operation of the piece automatic separation system in this embodiment is as follows.

[0075] The flipping drive mechanism 4.2 drives the flipping base 4.3 to rotate, so that the gripper 4.6 is distributed downward.

[0076] The lifting mechanism 5 drives the gripper 4.6 to descend to a specified position. At this time, the gripper 4.6 adheres to the edge position of the uppermost piece in the stacked pieces, and grabs the uppermost piece through the gripper 4.6.

[0077] Then, the lifting mechanism 5 drives the gripper 4.6 to move up to a specified position; the longitudinal translation mechanism 6 drives the lifting mechanism 5 and the gripper 4.6 to translate backward by a set distance L.

[0078] Then, the flipping drive mechanism 4.2 drives the flipping base 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward by a set angle (the set angle is generally 90 degrees. Of course, the specific set angle of the upward flip of the flipping base 4.3 can be set according to actual needs), so that a part of the edge of the piece grabbed by the gripper 4.6 is distributed forward or upward or obliquely upward; in this way, this part of the edge of the piece distributed forward or upward or obliquely upward can enter the jaws 8.1 of the manipulator 8 straight, effectively avoiding the problem that when the edge of the piece enters the jaws 8.1, it will bend and fold, making it difficult to enter the jaws 8.1 straight, and it is easy to have the edge of the piece folded in the jaws 8.1 of the manipulator 8, resulting in the problem of folding marks and hemming of the piece. At the same time, the separation of single-layer pieces is smoothly achieved.

[0079] On the other hand, during the process of separating the cut pieces (grasping and separating the topmost cut piece), on the one hand, the cut pieces in the stacked state will be pressed by the cloth pressing rollers 3.4.1, effectively preventing one or more lower cut pieces from being adhered and lifted, thus avoiding wrinkles, arching, and misalignment of the cut pieces from the specified position, which may lead to failure in grasping and separating the subsequent cut pieces; on the other hand, the cloth pressing rollers 3.4.1 can roll, so as to ensure that the topmost cut piece can be smoothly grasped and separated, avoiding the problem that the frictional force during the cut piece separation process is too large and affecting the cut piece separation.

[0080] Specifically, as Figures 1-3 shown, the automatic cut piece separation system further includes a horizontal translation mechanism 7 and a manipulator 8 for grasping the cut pieces. The manipulator 8 includes a jaw 8.1 for grasping the cut pieces. The specific manner and structure of the manipulator 8 and the jaw 8.1 are prior arts, and their specific structures are not the novel points of the present application. Therefore, the present application does not elaborate on the specific manner and structure of the manipulator 8 and the jaw 8.1 and other conventional technical means. When the flipping drive mechanism 4.2 drives the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward by a set angle (generally 90 degrees upward), so that a part of the edge of the cut piece grasped by the gripper 4.6 is distributed forward, upward, or obliquely upward, the manipulator 8 moves the jaw 8.1, so that this part of the cut piece edge distributed forward, upward, or obliquely upward can enter the jaw 8.1 of the manipulator 8 straightly, and then the jaw 8.1 clamps the cut piece and moves it forward, thus realizing the single-layer separation of the cut piece.

[0081] In this embodiment, as Figures 1-4 shown, the horizontal translation mechanism 7 is located above the cut piece placement table 1. The longitudinal translation mechanism 6 drives the horizontal translation mechanism 7 to translate along the front and back directions of the cut piece placement table 1. The longitudinal translation mechanism 6 includes a longitudinal translation slide 6.1, and the horizontal translation mechanism 7 is arranged on the longitudinal translation slide 6.1. The longitudinal translation mechanism 6 drives the longitudinal translation slide 6.1 to translate along the front and back directions of the cut piece placement table 1, and further drives the horizontal translation mechanism 7 to translate along the front and back directions of the cut piece placement table 1.

[0082] In this embodiment, the longitudinal translation mechanism 6 is composed of horizontally distributed linear modules. The linear module can be one; it can also be two mutually parallel linear modules. The linear module extends along the front and back directions of the cut piece placement table 1. The linear module can be of the synchronous belt type, ball screw type, or linear motor type. As Figure 1 shown, the longitudinal translation mechanism 6 is composed of two mutually parallel linear modules, and the two linear modules share the same drive motor; each linear module includes a longitudinal translation slide 6.1, and the horizontal translation mechanism 7 is arranged on the longitudinal translation slides 6.1 of the two linear modules.

[0083] Of course, it should be noted that the longitudinal translation mechanism 6 can also be other horizontal translation mechanisms in the prior art, such as electric cylinders, etc.

[0084] In this embodiment, as Figures 1-4 shown, the horizontal translation mechanism 7 includes a cross-slide 7.1. The lifting mechanism 5 is arranged on the cross-slide 7.1. The horizontal translation mechanism 7 drives the cross-slide 7.1 and the lifting mechanism 5 to translate in the left-right direction along the piece placing table 1. The moving direction of the cross-slide 7.1 is perpendicular to the moving direction of the longitudinal slide 6.1. The rotation axis of the flipping seat 4.3 is parallel to the moving direction of the cross-slide 7.1. In this way, the horizontal translation mechanism 7 can drive the cross-slide 7.1 and the lifting mechanism 5 to translate, so as to drive the single-piece separation mechanism 4 of the pieces to move to the designated position, thus meeting the needs of different grasping parts of different pieces and improving the adaptability of the automatic piece separation system.

[0085] In this embodiment, the horizontal translation mechanism 7 is composed of a linearly arranged module horizontally distributed, and this linearly arranged module extends in the left-right direction along the piece placing table 1. This linearly arranged module can be of the synchronous belt type or the ball screw type or the linear motor type.

[0086] Of course, it should be noted that the horizontal translation mechanism 7 can also be other horizontal translation mechanisms in the prior art, for example, an electric cylinder, etc.

[0087] In this embodiment, as Figures 1-4 shown, the lifting mechanism 5 is a linearly arranged module vertically distributed. This linearly arranged module can be of the synchronous belt type or the ball screw type or the linear motor type. Using the vertically distributed linearly arranged module as the lifting mechanism 5 can flexibly and accurately drive the lifting seat 5.1 to lift to the designated position.

[0088] Of course, it should be noted that the lifting mechanism 5 can also be a vertically distributed air cylinder or an electric cylinder, etc.

[0089] Furthermore, the grippers 4.6 in the same single-piece separation mechanism 4 of the pieces are one or more.

[0090] In one implementation manner, as Figure 1 , Figure 5 shown, the gripper 4.6 in the same single-piece separation mechanism of the pieces is one. Using one gripper to grasp the pieces has a simple structure and can reduce the manufacturing cost.

[0091] In another implementation manner, the grippers 4.6 in the same single-piece separation mechanism of the pieces are multiple (not shown in the figure), for example, the grippers are two or three or four or more. The multiple grippers are arranged on the same side of the flipping seat. The number of grippers can be arranged according to actual needs. The multiple grippers can achieve a better grasping effect and are beneficial to applications in cases where the piece area is large or the shape is complex.

[0092] In this embodiment, the mounting seat 4.1 is plate-shaped. Of course, the mounting seat can also be block-shaped or in a bracket structure, etc.

[0093] In the embodiment, as Figure 5 shown, a limiting surface is provided on the mounting base 4.1. When the flipping base 4.3 abuts against the limiting surface, the gripper 4.6 is distributed downward. The gripper in this state is used to grip the uppermost layer of cut pieces. Specifically, the driving actuator drives the moving block to move, driving the flipping base to flip until the flipping base abuts against the limiting surface. At this time, the gripper is distributed downward.

[0094] Furthermore, as Figure 5 shown, the driving actuator 4.21 is a cylinder or an electric cylinder. The telescopic rod of the cylinder or electric cylinder is fixedly connected to the moving block. Of course, it should be noted that the driving actuator can also be other mechanisms in the prior art, such as an electric push rod, a linear motor, etc. In this embodiment, the driving actuator is an electric cylinder. In this way, not only can the flipping base be driven to flip upward or downward by the electric cylinder drive, but also the flipping angle of the flipping base to flip upward or downward can be set as needed. For example, during or after the upward movement of the gripper, the electric cylinder can control the moving distance of the moving block to control the flipping angle of the flipping base upward, so that a part of the edge of the cut piece gripped by the gripper faces forward or upward or obliquely upward.

[0095] Specifically, a connection port is provided on the moving block 4.22 on the side facing the electric cylinder. The end of the telescopic rod of the electric cylinder extends into the connection port, and the telescopic rod of the electric cylinder is fixedly connected to the moving block.

[0096] Furthermore, as Figure 5 shown, a support plate 4.7 is provided on the flipping base. The gripper is mounted on the support plate. In this way, the structure and size of the support plate can be adjusted as needed, and then it is convenient to adjust the mounting position of the gripper to meet the needs of different gripping parts of the gripper for different cut pieces.

[0097] Furthermore, as Figure 5 shown, a fixing block 4.5 is provided on the mounting base 4.1. The flipping base is rotatably arranged on the fixing block so as to be able to flip in the up and down direction. In this way, it is convenient for the installation of the flipping base.

[0098] Specifically, a mounting opening is provided on the fixing block. The mounting opening is rectangular. The flipping base is provided with a convex block. The convex block is rectangular. The convex block extends into the mounting opening. The rotation shaft 4.4 of the flipping base passes through the mounting opening and the convex block, so that the flipping base can flip in the up and down direction.

[0099] In one example, the fixing block is fixed to the mounting base by bolts. In this way, it is convenient for the installation of the fixing block and the flipping base. Of course, the fixing block can also be installed on the mounting base by welding or riveting or bonding or other methods.

[0100] Specific Embodiment 2. The remaining structure of this embodiment refers to Specific Embodiment 1, and the difference lies in that

[0101] As Figure 1 , Figure 2 , Figure 3 , Figure 6 shown, the cloth pressing mechanism 3 includes a cloth pressing driving mechanism 3.1 and a mounting portion 3.2. The cloth pressing assembly 3.4 is arranged on the mounting portion 3.2. The cloth pressing driving mechanism 3.1 drives the mounting portion 3.2 to move up and down.

[0102] The cloth pressing assembly 3.4 further includes a guiding member 3.4.2 and an elastic element 3.4.3. The guiding member 3.4.2 is slidably connected to the mounting portion 3.2 in the up and down direction. The cloth pressing roller 3.4.1 is rotatably arranged at the bottom of the guiding member 3.4.2. The elastic element 3.4.3 provides an elastic force to drive the guiding member 3.4.2 and the cloth pressing roller 3.4.1 to move downward, so that the cloth pressing roller 3.4.1 presses on the stacked cut pieces.

[0103] In one embodiment, there is one cloth pressing assembly 3.4 for the same cloth pressing mechanism 3.

[0104] In another embodiment, there are multiple cloth pressing assemblies 3.4 for the same cloth pressing mechanism 3 (not shown in the figure), for example, there are 2 or 3 or 4 cloth pressing assemblies 3.4. The rotating shafts of the cloth pressing rollers 3.4.1 of the multiple cloth pressing assemblies 3.4 are parallel. The multiple cloth pressing assemblies 3.4 can be arranged side by side, or can be arranged staggeredly according to needs. The number of the cloth pressing assemblies 3.4 can be arranged according to actual needs. The multiple cloth pressing assemblies 3.4 can achieve a better cloth pressing effect. During the process of separating the cut pieces (grasping and separating the uppermost cut piece), it can more effectively avoid sticking and lifting one or more lower layers of cut pieces.

[0105] The cloth pressing mechanism 3 works as follows. The cloth pressing driving mechanism 3.1 drives the mounting portion 3.2 and the cloth pressing assembly 3.4 to move downward by a specified distance, so that the cloth pressing roller 3.4.1 presses on the stacked cut pieces and compresses the elastic element 3.4.3. The pressure exerted by the cloth pressing roller 3.4.1 on the cut pieces is provided by the elastic element 3.4.3. Thus, during the process of separating the cut pieces (grasping and separating the uppermost cut piece), on the one hand, the stacked cut pieces will be pressed by the cloth pressing roller 3.4.1, effectively avoiding sticking and lifting one or more lower layers of cut pieces, thereby avoiding the cut pieces from being wrinkled, arched, or misaligned from the specified position, which may lead to the failure of subsequent grasping and separating of the cut pieces. On the other hand, the pressure exerted by the cloth pressing roller 3.4.1 on the cut pieces is provided by the elastic element 3.4.3, which can avoid the pressure exerted by the cloth pressing roller 3.4.1 on the cut pieces from being too large. At the same time, the cloth pressing roller 3.4.1 can roll, so it can ensure that the uppermost cut piece can be smoothly grasped and separated, avoiding the problem that the friction force received during the process of separating the cut pieces is too large, which affects the separation of the cut pieces.

[0106] The cloth pressing driving mechanism 3.1 drives the mounting part 3.2 to move up and down. Specifically,

[0107] In one implementation of this embodiment, the cloth pressing drive mechanism 3.1 is a cylinder, such as a double-axis cylinder, and the mounting portion 3.2 is directly mounted on the end of the telescopic rod of the double-axis cylinder, and the cloth pressing drive mechanism 3.1 can drive the mounting portion 3.2 to move up and down smoothly only by the double-axis cylinder; there is no need to arrange a guide rail or other structure to guide the movement of the mounting portion 3.2.

[0108] Of course, the cloth pressing drive mechanism 3.1 can also be a single-axis cylinder. If a single-axis cylinder is used, it generally needs to be matched with a guide rail, that is, the mounting part 3.2 is installed on the slider of the guide rail, and the movement of the mounting part 3.2 is guided by the guide rail.

[0109] In another implementation of the present embodiment, the cloth pressing drive mechanism 3.1 is an electric cylinder or an electric push rod. The mounting portion 3.2 can be directly mounted on the end of the telescopic rod of the electric cylinder or the electric push rod, and the mounting portion 3.2 can be directly driven to move up and down by the electric cylinder or the electric push rod; the mounting portion 3.2 can be driven to move up and down in cooperation with the guide rail, that is, the mounting portion 3.2 is mounted on the slider of the guide rail, and the movement of the mounting portion 3.2 is guided by the guide rail. If the cloth pressing drive mechanism 3.1 is an electric cylinder or an electric push rod, the up and down movement stroke of the mounting portion 3.2 can be adjusted by the electric cylinder or the electric push rod as needed to meet actual needs. For example, in the process of separating the cut pieces, as the height of the cut pieces in the stacked state gradually decreases, the height of the mounting portion 3.2 can be gradually lowered by the electric cylinder or the electric push rod, so that the pressure of the cloth pressing roller 3.4.1 on the cut pieces remains consistent.

[0110] Of course, it should be noted that the cloth pressing driving mechanism 3.1 can also be other cloth pressing driving mechanisms 3.1 in the prior art.

[0111] In this embodiment, the moving direction of the mounting part 3.2 is parallel to the sliding direction of the guide member 3.4.2. Thus, in the process that the cloth pressing driving mechanism 3.1 drives the mounting part 3.2 and the cloth pressing assembly 3.4 to move downward, when the cloth pressing roller 3.4.1 first presses on the stacked pieces, and then the cloth pressing driving mechanism 3.1 drives the mounting part 3.2 to continue to move downward, since the moving direction of the mounting part 3.2 is parallel to the sliding direction of the guide member 3.4.2, it is beneficial for the guide member 3.4.2 to slide upward, thereby compressing the elastic element 3.4.3, until the mounting part 3.2 moves downward to the specified position.

[0112] Further, such as Figure 6As shown in the figure, a flexible cloth pressing device further includes a mounting bracket 3.3. The cloth pressing driving mechanism 3.1 is mounted on the mounting bracket 3.3 by bolts. For example, the cloth pressing driving mechanism 3.1 is mounted on the mounting bracket 3.3 by bolts. In this way, it is convenient to install and arrange the cloth pressing driving mechanism 3.1.

[0113] Furthermore, as Figure 6 shown in the figure, the mounting part 3.2 is a mounting plate, and the mounting plate is perpendicular to the moving direction of the mounting part 3.2. Of course, it should be noted that the mounting part 3.2 can also be other structures, such as a bracket structure or other integral structures.

[0114] Furthermore, as Figure 6 shown in the figure, the cloth pressing assembly 3.4 further includes a guide sleeve 3.4.4 provided on the mounting part 3.2. The guide holes in the guide sleeve 3.4.4 are distributed extending vertically. The guide member 3.4.2 is a guide rod. The guide rod is inserted into the guide sleeve 3.4.4 and can slide up and down along the guide sleeve 3.4.4. In this way, it is ensured that the guide member 3.4.2 can slide up and down smoothly along the guide sleeve 3.4.4, and it is convenient to manufacture.

[0115] The installation method of the guide sleeve 3.4.4 can be selected according to needs. For example, the guide sleeve 3.4.4 is installed on the mounting part 3.2 by bolts or riveting, or the guide sleeve 3.4.4 is installed on the mounting part 3.2 by welding.

[0116] The guide rod can slide up and down along the guide sleeve 3.4.4, and there is no relative rotation between the guide rod and the guide sleeve 3.4.4. For example, one of the guide rod and the guide sleeve 3.4.4 is provided with axially extending ridges, and the other is provided with guide grooves cooperating with the ridges.

[0117] In this embodiment, as Figure 6As shown in the figure, the outer side of the guide sleeve 3.4.4 is provided with an external thread, and the installation part 3.2 is provided with installation screw holes extending vertically. The guide sleeve 3.4.4 is threadedly connected to the installation screw holes through the external thread. The lower part of the guide rod is provided with a lower blocking part. In this embodiment, the lower part of the guide rod is provided with an annular step surface, and this annular step surface constitutes the lower blocking part. The lower blocking part is located below the guide sleeve 3.4.4. The elastic element 3.4.3 is a spring. The spring is sleeved on the guide rod and pressed between the guide sleeve 3.4.4 and the lower blocking part. In this way, on the one hand, the guide sleeve 3.4.4 can be conveniently installed on the installation part 3.2; on the other hand, by rotating the guide sleeve 3.4.4, the height of the entire cloth pressing assembly 3.4 can be adjusted, and then the pressure of the cloth pressing roller 3.4.1 on the stacked cut pieces can be adjusted to adapt to the pressing requirements of different fabrics; for example, by rotating the guide sleeve 3.4.4, the height of the entire cloth pressing assembly 3.4 is adjusted downward. In this way, when the cloth pressing drive mechanism 3.1 drives the installation part 3.2 and the cloth pressing assembly 3.4 to move downward by a specified distance (the height of the stacked cut pieces remains unchanged), the cloth pressing roller 3.4.1 presses on the stacked cut pieces and compresses the elastic element 3.4.3. During this process, the compression amount of the elastic element 3.4.3 (spring) increases, so that the pressure of the cloth pressing roller 3.4.1 on the stacked cut pieces can be increased. Or by rotating the guide sleeve 3.4.4, the height of the entire cloth pressing assembly 3.4 is adjusted upward. In this way, when the cloth pressing drive mechanism 3.1 drives the installation part 3.2 and the cloth pressing assembly 3.4 to move downward by a specified distance (the height of the stacked cut pieces remains unchanged), the cloth pressing roller 3.4.1 presses on the stacked cut pieces and compresses the elastic element 3.4.3. During this process, the compression amount of the elastic element 3.4.3 (spring) decreases, so that the pressure of the cloth pressing roller 3.4.1 on the stacked cut pieces can be reduced.

[0118] Further, as Figure 6 shown, the lower end of the guide sleeve 3.4.4 is provided with an annular block extending outward. In this way, when installing the guide sleeve 3.4.4, the guide sleeve 3.4.4 can be rotated until the annular block abuts against the lower end of the installation screw hole, so as to keep the initial installation height of the guide sleeve 3.4.4 consistent.

[0119] Further, the upper end of the guide rod is provided with an upper blocking part, and the upper blocking part is located above the guide sleeve 3.4.4. In this way, the guide rod can be prevented from detaching from the guide sleeve 3.4.4.

[0120] Further, as Figure 6 shown, the bottom of the guide member 3.4.2 is provided with a roller bracket 3.4.5, and the cloth pressing roller 3.4.1 is rotatably arranged on the roller bracket 3.4.5. In this way, it is convenient to install the cloth pressing roller 3.4.1. The roller bracket 3.4.5 is in an inverted U shape.

[0121] Further, the roller brackets 3.4.5 are fixedly locked to the bottom of the guide member 3.4.2 by bolts. In this embodiment, the roller brackets 3.4.5 are fixedly locked to the bottom of the guide rod by bolts. This facilitates the installation and disassembly of the roller brackets 3.4.5. Of course, it should be noted that the roller brackets 3.4.5 are fixed to the bottom of the guide member 3.4.2 by welding, riveting or other means.

[0122] Specific Embodiment 3, a method for separating cut pieces using a cut piece automatic separation system, the specific structure of the cut piece automatic separation system in this cut piece separation method refers to Specific Embodiment 1 or Specific Embodiment 2.

[0123] A method for separating cut pieces using a cut piece automatic separation system successively includes the following steps:

[0124] First, the flipping drive mechanism 4.2 drives the flipping seat 4.3 to rotate, so that the grippers 4.6 are distributed downward.

[0125] Second, the lifting mechanism 5 drives the grippers 4.6 to descend to a specified position. At this time, the grippers 4.6 are attached to the edge position of the uppermost cut piece in the stacked cut pieces, and the uppermost cut piece is grabbed by the grippers 4.6.

[0126] Third, the lifting mechanism 5 drives the grippers 4.6 to move upward to a specified position.

[0127] Then, the longitudinal translation mechanism 6 drives the lifting mechanism 5 and the grippers 4.6 to translate backward by a set distance L.

[0128] Fourth, the flipping drive mechanism drives the flipping seat to rotate, thereby driving the grippers to flip forward and upward by a set angle (the set angle ranges from 90 to 120 degrees. In this embodiment, the set angle is 90 degrees), so that a part of the cut piece edges grabbed by the grippers 4.6 are distributed forward, upward or obliquely upward. In the text "the flipping drive mechanism drives the flipping seat to rotate, thereby driving the grippers to flip forward and upward by a set angle", the forward and upward flipping of the grippers means that the grippers flip upward toward the front side of the cut piece placement table around the rotation axis of the flipping seat.

[0129] Fifth, the manipulator 8 grabs this part of the cut piece edges distributed forward, upward or obliquely upward on the grippers 4.6;

[0130] Then, the manipulator 8 moves the cut piece forward to separate the cut piece from the pressing cloth roller 3.4.1, thereby realizing the single-layer separation of the cut piece.

[0131] In the fourth step, the flipping drive mechanism 4.2 drives the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward by a set angle, so that a part of the edge of the cut piece grasped by the gripper 4.6 is distributed forward, upward or obliquely upward; in this way, this part of the edge of the cut piece that is forward, upward or obliquely upward can enter the jaws 8.1 of the manipulator 8 straightly, effectively avoiding the problem that when the edge of the cut piece enters the jaws 8.1, it will bend and fold, making it difficult to enter the jaws 8.1 straightly, and it is easy to have the edge of the cut piece folded in the jaws 8.1 of the manipulator 8, resulting in the problem of folding marks and hemming of the cut piece. At the same time, the separation of single-layer cut pieces is smoothly achieved.

[0132] On the other hand, the utility model person found that during the separation process of the cut piece, if in the above-mentioned third step, after the lifting mechanism 5 drives the gripper 4.6 to move up to the designated position and then directly executes the fourth step, that is, the flipping drive mechanism 4.2 drives the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward, the distance between the gripper 4.6 and the cloth pressing roller 3.4.1 in the front-rear direction increases, and the gripper 4.6 will drag the cut piece forward. Since the rear part of the cut piece is pressed by the cloth pressing roller 3.4.1, the following problems are likely to occur.

[0133] If the gripper 4.6 is a needle-piercing suction cup (the needle-piercing suction cup uses needles to insert into the cut piece fabric to grasp the cut piece), during the process of the flipping drive mechanism 4.2 driving the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward, since the rear part of the cut piece is pressed by the cloth pressing roller 3.4.1, holes will appear in the cut piece under the pulling of the needles (one needle forms one hole, and finally a piece of holes is formed), thus affecting the quality of the cut piece.

[0134] If the gripper 4.6 is a vacuum suction cup, during the process of the flipping drive mechanism 4.2 driving the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward, since the rear part of the cut piece is pressed by the cloth pressing roller 3.4.1, the vacuum suction cup is likely to be separated from the cut piece, resulting in the failure of cut piece separation.

[0135] To solve the above problems, in the process of the lifting mechanism 5 driving the gripper 4.6 to move upward to a specified position, or after the lifting mechanism 5 drives the gripper 4.6 to move upward to the specified position, an additional operation is added, that is, "the longitudinal translation mechanism 6 drives the lifting mechanism 5 and the gripper 4.6 to move backward by a set distance L", so as to reduce the distance between the gripper 4.6 and the pressing rollers 3, 4, and 1 in the front-back direction (the uppermost grabbed piece of fabric forms wrinkles between the gripper 4.6 and the pressing rollers 3, 4, and 1). After that, the fourth step is executed, that is, the flipping drive mechanism 4.2 drives the flipping seat 4.3 to rotate, thereby driving the gripper 4.6 to flip forward and upward. Although the distance between the gripper 4.6 and the pressing rollers 3, 4, and 1 in the front-back direction increases during this process, it exactly cancels out the "reduction of the distance between the gripper 4.6 and the pressing rollers 3, 4, and 1 in the front-back direction" in the third step. Therefore, the gripper 4.6 will not pull the piece of fabric, so that there will be no holes when using a needle-punching suction cup to grab the piece of fabric; when using a vacuum suction cup to grab the piece of fabric, it will not separate from the piece of fabric, resulting in the failure of piece separation, thus effectively solving the above problems.

[0136] Further, in the above first step, according to actual needs, the single-layer piece separation mechanism 4 of the piece of fabric can also be translated to a specified piece-grabbing position through the longitudinal translation mechanism 6 and the lateral translation mechanism 7.

[0137] The above description is only a preferred embodiment of the present invention and does not impose any limitations on the present invention. Any simple modification, change, and equivalent transformation made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
