Description

Technical Field

[0001] The utility model relates to the technical field of cutting piece separation, in particular to a device for separating cutting pieces by shifting. Background Art

[0002] Despite the widespread adoption of automation technology in many fields, the garment manufacturing industry still relies extensively on hand sewing. This is primarily because most existing automated sewing equipment still requires manual loading, which limits production efficiency and increases costs. A key obstacle to the future development of unmanned automated sewing equipment is the lack of automatic piece separation technology, a prerequisite for fully automated processes. Piece separation technology involves automatically picking up stacked pieces in single layers, from top to bottom. Piece separation technology is often used in automated and unmanned garment production equipment and workstations as a loading module.

[0003] Currently, the main method for separating cut pieces is a combination of suction cups and a robotic arm. The suction cups include vacuum cups and needle-punched cups. The cups grasp the cut pieces, and then a lifting mechanism drives the gripper upward, sucking up a layer of cut pieces. The robotic arm then grabs the sucked-up pieces and moves them to the target location. This current method of separating cut pieces has the following drawbacks: vacuum cups can only be used on fabrics with poor breathability; otherwise, they can easily fail to hold the pieces together, resulting in high energy consumption and noise. Needle-punched cups also pose a risk of damaging the fabric, especially coated and sensitive fabrics. Utility Model Content

[0004] The purpose of the utility model is to provide a device for separating cutting pieces which has good versatility, can be applied to the separation of various types of cutting pieces of fabric, and can effectively avoid damaging the fabric.

[0005] The technical solution of the utility model is:

[0006] A device for separating cut pieces by shifting, comprising:

[0007] Mounting bracket;

[0008] The joint part is rotatable in the up and down directions and is arranged on the mounting bracket;

[0009] The hind limbs, middle limbs and forelimbs are hingedly connected in sequence, and the rotation of the hind limbs is set on the joint parts;

[0010] a rear link located between the joint member and the middle limb, one end of the rear link being hinged to the joint member, and the other end of the rear link being hinged to the middle limb;

[0011] A front link located between the hind limbs and the forelimbs, with one end of the front link hinged to the hind limbs and the other end of the front link hinged to the forelimbs;

[0012] The driving device drives the joint to rotate. The specific working of the device for separating the cutting pieces in this solution is as follows:

[0013] The driving device drives the joint to rotate downward. During this process, the rear connecting rod will drive the middle limb to rotate downward. During the downward rotation of the middle limb, the front connecting rod will cooperate to make the forelimb rotate downward and move backward (simulating the action of bending the fingers downward). During this process, the forelimb will press on the topmost piece close to the front side of the piece and push it backward, so that the front side of the topmost piece will be tilted upward; then, the gripper of the robot can grab the tilted front side of the topmost piece and move the piece to the target position to achieve piece separation.

[0014] Compared with the prior art which uses vacuum suction cups to absorb the cut pieces, which can only be applied to fabrics with poor air permeability, otherwise it is easy to have problems with not being able to absorb the fabric, and the use of needle-punched suction cups has the risk of damaging the fabric; the cutting piece separation device of this scheme simulates the action of bending the fingers downward, and uses the forelimbs to press on the top cut piece close to the front side of the cut piece and push it backward, so that the front side of the top cut piece is tilted upward to separate the cut pieces. It has good versatility and can be applied to the separation of various types of cut piece fabrics without damaging the fabric.

[0015] Preferably, the front end of the forelimb is in an arc shape. When the forelimb is pressed against the topmost panel near the front edge of the panel and is moved backward to tilt the front edge of the topmost panel upward, the front end of the forelimb will often come into contact with the panel. Therefore, in this solution, the front end of the forelimb is configured in an arc shape, which can effectively prevent the front end of the forelimb from causing damage to the panel fabric during the contact process.

[0016] Preferably, the front limb is provided with a downwardly protruding toggle portion, and the surface of the toggle portion is arc-shaped. In this way, the arc-shaped toggle portion can be pressed on the topmost panel near the front side of the panel and toggle backward, which is conducive to causing the front side of the topmost panel to tilt upward and at the same time helps to avoid damage to the panel fabric.

[0017] Preferably, the driving device comprises:

[0018] Translation block;

[0019] The translation actuator drives the translation block to move;

[0020] The driving link has one end hinged to the translation block, and the other end intersects with the joint component. The specific operation of the driving device of this solution is as follows: the translation actuator drives the translation block to move, thereby driving the joint component downward or upward through the driving link. Its structure is simple and easy to layout.

[0021] Preferably, the translation actuator is a pneumatic cylinder or an electric cylinder.

[0022] Preferably, the driving device further comprises a guide rod, which is fixed to the mounting bracket, and the translation block slides along the guide rod. In this way, the translation block can be ensured to move smoothly, thereby enabling the driving device to steadily drive the joint member to rotate downward or upward.

[0023] Preferably, the driving device includes a driving motor. In this solution, the driving motor is used to drive the joint member to rotate downward or upward.

[0024] Preferably, a mounting block is provided on the mounting bracket, and the joint component is arranged on the mounting block so as to be rotatable in the up-down direction, thereby facilitating the installation of the joint component.

[0025] Preferably, the mounting block is connected to the mounting bracket by bolts, so as to facilitate the installation of the mounting block and the joint member.

[0026] Preferably, the forelimbs are plastic parts. In this way, when the forelimbs are pressed on the topmost panel near the front side of the panel and moved backward to make the front side of the topmost panel tilt upward, the forelimbs can effectively prevent the panel fabric from being damaged.

[0027] The beneficial effects of the utility model are: good versatility, applicable to the separation of various types of cut fabrics, and capable of effectively avoiding damage to the fabrics. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Specific embodiment 1, as Figure 1 、 Figure 2 As shown, a device for separating cut pieces by shifting includes a mounting bracket 1, a joint part 2, "a hind limb 3, a middle limb 4 and a front limb 5 hingedly connected in sequence", a rear connecting rod 6 and a front connecting rod 7.

[0042] The joint component 2 is rotatably mounted on the mounting bracket 1 in the up-down direction.

[0043] The hind limb 3, the middle limb 4 and the forelimb 5 are hingedly connected in sequence, that is, the hind limb 3, the middle limb 4 and the forelimb 5 are arranged in sequence, the hind limb 3 is hingedly connected to the middle limb 4, and the middle limb 4 is hingedly connected to the forelimb 5. The hind limb 3 is rotatably arranged on the joint part 2.

[0044] The rear link 6 is located between the joint 2 and the middle limb 4. One end of the rear link 6 is hinged to the joint 2, and the other end of the rear link 6 is hinged to the middle limb 4. A four-bar mechanism is formed between the joint 2, the hind limb 3, the middle limb 4 and the rear link 6.

[0045] The front link 7 is located between the hind limb 3 and the forelimb 5. One end of the front link 7 is hinged to the hind limb 3, and the other end of the front link 7 is hinged to the forelimb 5. A four-bar mechanism is formed between the hind limb 3, the middle limb 4, the forelimb 5 and the front link 7.

[0046] The driving device 8 drives the joint component 2 to rotate.

[0047] The specific operation of the device for separating the cut pieces in this embodiment is as follows:

[0048] The device for separating the panels by shifting is mounted and fixed by a mounting bracket 1. For example, the mounting bracket 1 is mounted and fixed to the rack of a garment production device, thereby fixing the device to the rack of the garment production device. Panels 9 are stacked from bottom to top and placed below the "hind leg 3, middle leg 4, and front leg 5, which are hingedly connected in sequence."

[0049] When doing specific work, such as Figure 3As shown, the drive device 8 drives the joint member 2 to rotate downward. During this process, the rear link 6 drives the middle limb 4 to rotate downward. As the middle limb 4 rotates downward, the front link 7 cooperates with the front link 7 to cause the forelimb 5 to rotate downward and move backward (simulating the movement of a finger bending downward). During this process, the forelimb 5 presses against the topmost piece near the front edge of the piece and pushes it backward, causing a portion of the front edge of the topmost piece to tilt upward. The gripper of the manipulator then grasps the tilted front edge of the topmost piece and moves the piece to the target position, achieving separation. Next, the drive device 8 drives the joint member 2 to rotate upward and reset. During this process, the rear link 6 drives the middle limb 4 to rotate upward. During this upward rotation of the middle limb 4, the front link 7 cooperates with the front link 7 to cause the forelimb 5 to rotate upward and move forward to reset (simulating the movement of a finger bending upward).

[0050] Compared with the prior art which uses vacuum suction cups to absorb the cut pieces, which can only be applied to fabrics with poor air permeability, otherwise it is easy to have problems with not being able to absorb the fabric, and the use of needle-punched suction cups has the risk of damaging the fabric; the cutting piece separation device of this solution simulates the action of bending the fingers downward, and uses the forelimb 5 to press on the top cut piece close to the front side of the cut piece and to push it backward, so that the front side of the top cut piece is lifted up to separate the cut pieces. It has good versatility and can be applied to the separation of various types of cut piece fabrics without damaging the fabric.

[0051] Specific embodiment 2, as Figure 1 、 Figure 2 As shown, a device for separating cut pieces by shifting includes a mounting bracket 1, a joint part 2, "a hind limb 3, a middle limb 4 and a front limb 5 hingedly connected in sequence", a rear connecting rod 6 and a front connecting rod 7.

[0052] The joint component 2 is rotatable in the up-down direction and is arranged on the mounting bracket 1. In this embodiment, the rotation axis of the joint component 2 is horizontally distributed.

[0053] The hind limb 3, mid-limb 4, and forelimb 5 being sequentially articulated and connected refer to the following: the hind limb 3, mid-limb 4, and forelimb 5 are arranged in this order, the hind limb 3 and mid-limb 4 being articulated and connected, and the mid-limb 4 and forelimb 5 being articulated and connected. The hind limb 3 is pivotally mounted on the joint 2. In this embodiment, the articulation axis between the hind limb 3 and mid-limb 4 is parallel to the rotation axis of the joint 2. The "articulation axis between the hind limb 3 and mid-limb 4" is parallel to the "articulation axis between the mid-limb 4 and forelimb 5."

[0054] The rear link 6 is located between the joint 2 and the middle limb 4. One end of the rear link 6 is hinged to the joint 2, and the other end of the rear link 6 is hinged to the middle limb 4. A four-bar mechanism is formed between the joint 2, the hind limb 3, the middle limb 4 and the rear link 6.

[0055] The front link 7 is located between the hind limb 3 and the forelimb 5. One end of the front link 7 is hinged to the hind limb 3, and the other end of the front link 7 is hinged to the forelimb 5. A four-bar mechanism is formed between the hind limb 3, the middle limb 4, the forelimb 5 and the front link 7.

[0056] The driving device 8 drives the joint component 2 to rotate.

[0057] In one embodiment, the driving device 8 includes a translation block 8.1, a driving connecting rod 8.3 and a translation actuator 8.2. The translation actuator 8.2 drives the translation block 8.1 to move, and the moving direction of the translation block 8.1 is perpendicular to the rotation axis of the joint part 2, and the moving direction of the translation block 8.1 is horizontally distributed. One end of the driving connecting rod 8.3 is hinged to the translation block 8.1, and the other end of the driving connecting rod 8.3 is connected to the joint part 2. During specific operation, the translation actuator 8.2 drives the translation block 8.1 to move, thereby driving the joint part 2 to rotate downward or upward through the driving connecting rod 8.3. Its structure is simple and easy to layout. The translation actuator 8.2 is a pneumatic cylinder or an electric cylinder. The telescopic rod of the pneumatic cylinder or the electric cylinder is fixedly connected to the translation block 8.1. Of course, it should be noted that the translation actuator 8.2 can also be other translation mechanisms in the prior art, such as an electric push rod, a linear motor, etc. In this embodiment, the translation actuator 8.2 is an electric cylinder, so that not only can the electric cylinder drive the joint part 2 to rotate upward or downward, but also the angle of the joint part 2 to rotate upward or downward can be set as needed.

[0058] In another embodiment, the driving device 8 includes a driving motor (not shown in the figure). In this embodiment, the driving motor is used to drive the joint component 2 to rotate downward or upward.

[0059] In one example, the driving motor directly drives the joint 2 to rotate (not shown in the figure). In this way, the structure can be simplified and the cost can be reduced.

[0060] In another example, the drive motor is connected to the joint component 2 via a transmission mechanism, which drives the joint component 2 to rotate (not shown). For example, the drive motor is connected to the joint component 2 via a belt drive mechanism or a gear drive mechanism. The drive motor drives the joint component 2 to rotate via the belt drive mechanism or the gear drive mechanism. This facilitates the layout of the drive device 8.

[0061] The specific operation of the device for separating the cut pieces in this embodiment is as follows:

[0062] The device for separating the panels by shifting is mounted and fixed by a mounting bracket 1. For example, the mounting bracket 1 is mounted and fixed to the rack of a garment production device, thereby fixing the device to the rack of the garment production device. Panels 9 are stacked from bottom to top and placed below the "hind leg 3, middle leg 4, and front leg 5, which are hingedly connected in sequence."

[0063] When doing specific work, such as Figure 3 As shown, the drive device 8 drives the joint member 2 to rotate downward. During this process, the rear link 6 drives the middle limb 4 to rotate downward. As the middle limb 4 rotates downward, the front link 7 cooperates with the front link 7 to cause the forelimb 5 to rotate downward and move backward (simulating the movement of a finger bending downward). During this process, the forelimb 5 presses against the topmost piece near the front edge of the piece and pushes it backward, causing a portion of the front edge of the topmost piece to tilt upward. The gripper of the manipulator then grasps the tilted front edge of the topmost piece and moves the piece to the target position, achieving separation. Next, the drive device 8 drives the joint member 2 to rotate upward and reset. During this process, the rear link 6 drives the middle limb 4 to rotate upward. During this upward rotation of the middle limb 4, the front link 7 cooperates with the front link 7 to cause the forelimb 5 to rotate upward and move forward to reset (simulating the movement of a finger bending upward).

[0064] Compared with the prior art which uses vacuum suction cups to absorb the cut pieces, which can only be applied to fabrics with poor air permeability, otherwise it is easy to have problems with not being able to absorb the fabric, and the use of needle-punched suction cups has the risk of damaging the fabric; the cutting piece separation device of this solution simulates the action of bending the fingers downward, and uses the forelimb 5 to press on the top cut piece close to the front side of the cut piece and to push it backward, so that the front side of the top cut piece is lifted up to separate the cut pieces. It has good versatility and can be applied to the separation of various types of cut piece fabrics without damaging the fabric.

[0065] In this embodiment, the joint component 2 is triangular in shape. The rotation axis between the joint component 2 and the mounting bracket 1 is located at one corner of the triangular joint component 2; the hinge axis between the drive link 8.3 and the joint component 2 is located at another corner of the triangular joint component 2; the hinge axis between the rear link 6 and the joint component 2 is located at the third corner of the triangular joint component 2; and the hinge axis between the hind limb 3 and the joint component 2 is located between the hinge axis between the drive link 8.3 and the joint component 2 and the hinge axis between the rear link 6 and the joint component 2.

[0066] In this embodiment, the mounting bracket 1 is a mounting plate. Of course, the mounting bracket 1 can also be other structures.

[0067] Furthermore, the hind limb 3 has a hind limb mounting opening at one end facing the middle limb 4, one end of the middle limb 4 extends into the hind limb mounting opening, and the hinge axis between the hind limb 3 and the middle limb 4 is located within the hind limb mounting opening. The forelimb 5 has a forelimb mounting opening at one end facing the middle limb 4, the other end of the middle limb 4 extends into the forelimb mounting opening, and the hinge axis between the forelimb 5 and the middle limb 4 is located within the forelimb mounting opening. This helps improve the compactness of the structure and the stability of the hind limb 3, middle limb 4, and forelimb 5, which are sequentially hingedly connected.

[0068] Furthermore, the front end of the forelimb 5 is in an arc shape. When the forelimb 5 is pressed against the topmost panel near the front edge of the panel and pushed back to cause the front edge of the topmost panel to tilt upward, the front end of the forelimb 5 will often come into contact with the panel. Therefore, the front end of the forelimb 5 is configured in an arc shape in this embodiment. This effectively prevents damage to the panel fabric during the contact between the front end of the forelimb 5 and the panel.

[0069] Furthermore, the forelimb 5 is a plastic part. In this way, when the forelimb 5 is pressed on the topmost panel near the front side of the panel and moved backward to make the front side of the topmost panel tilt upward, the forelimb 5 can effectively avoid damaging the panel fabric.

[0070] Of course, it needs to be said that the forelimb 5 can also be made of metal material.

[0071] Furthermore, the front limb 5 is provided with a downwardly protruding shifting portion 5.1, and the surface of the shifting portion 5.1 is arc-shaped. Thus, the arc-shaped shifting portion 5.1 can be pressed against the topmost panel near the front edge of the panel and shifted backward, thereby helping to tilt the front edge of the topmost panel upward and preventing damage to the panel fabric.

[0072] In one example, the front limb 5 and the toggle portion 5.1 are integrally formed, which facilitates the processing and manufacturing of the front limb 5 and the toggle portion 5.1.

[0073] In another example, the forelimb 5 and the toggle portion 5.1 are made separately, and the toggle portion 5.1 is fixed to the forelimb 5 by bonding, welding, bolting, or riveting. In this way, the toggle portion 5.1 of different materials and shapes can be replaced according to actual needs to adapt to the separate use of cut fabrics of different materials.

[0074] Furthermore, the driving device 8 also includes a guide rod 8.4. The guide rod 8.4 is fixed to the mounting bracket 1, and the translation block 8.1 slides along the guide rod 8.4. A guide hole that cooperates with the guide rod 8.4 is provided on the translation block 8.1, and the guide rod 8.4 passes through the guide hole. In this embodiment, the guide rod 8.4 is perpendicular to the rotation axis of the joint part 2, and the guide rod 8.4 is horizontally distributed. In this way, the smooth movement of the translation block 8.1 can be ensured, and the driving device 8 can then smoothly drive the joint part 2 to rotate downward or upward.

[0075] Furthermore, a mounting block 1.1 is provided on the mounting bracket 1. The joint member 2 is rotatably mounted on the mounting block 1.1 in the vertical direction, thereby facilitating the installation of the joint member 2. One end of the guide rod 8.4 is fixed to the mounting block 1.1.

[0076] The mounting block 1.1 is connected to the mounting bracket 1 by bolts. In this way, it is convenient to install the mounting block 1.1 and the joint member 2. Of course, the mounting block 1.1 can also be installed on the mounting bracket 1 by welding, riveting, bonding or other means.

[0077] The above are only the preferred embodiments of the present invention, and do not impose any restrictions on the present invention. Any simple modifications, changes and equivalent transformations 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.
