Description

Technical Field

[0001] The present invention relates to the technical field of dyeing and finishing equipment for open-width flexible fabrics, and in particular to a device and method for tearing open-width flexible fabrics. Background Art

[0002] Open-width flexible fabrics are still labor-intensive in the entire dyeing and finishing industry. Due to the wide range of variations in material properties such as width, thickness and elasticity of open-width flexible fabrics and the wide variety of types, coupled with the poor rigidity of the flexible fabrics themselves, the seams can only be torn off manually to ensure the integrity of the weft threads at the fabric break, thereby reducing fabric waste. However, this method involves a lot of manual intervention in the production process, a poor production environment, high labor intensity, and poor stability, resulting in low production efficiency and quality, and high labor costs. There is no mature technology in the industry yet, and there is an urgent need for a open-width flexible fabric tearing device to solve the above pain points and fill the gap in the industry. Summary of the Invention

[0003] In view of this, the present invention discloses a device and method for tearing open-width flexible cloth, the specific scheme of which is as follows:

[0004] A device for tearing open-width flexible cloth, comprising a rotary cloth-tearing chuck, a linear travel support, and a linear travel drive mechanism;

[0005] The linear travel support comprises a support, a rack, and a guide rail, wherein the rack and the guide rail are both arranged on the support, and the length directions of the rack and the guide rail are arranged in parallel directions;

[0006] The linear travel drive mechanism includes a drive motor, a gear, and a chuck bracket. The chuck bracket is arranged on the guide rail of the linear travel bracket, and a slider that cooperates with the guide rail is provided on the chuck bracket so that the chuck bracket can slide freely on the guide rail. The drive motor is arranged on the chuck bracket, and the gear is arranged on the rotating shaft of the motor and meshes with the rack of the linear travel bracket.

[0007] The rotary cloth tearing chuck includes a chuck fixing part, a chuck moving part, a cylinder, a fixed jaw, and a moving jaw. The chuck fixing part is arranged on the chuck bracket, the cylinder is arranged on the chuck fixing part, the chuck moving part is located below the chuck fixing part, the piston rod end of the cylinder is connected to the chuck moving part, the fixed jaw is arranged on the chuck fixing part, the moving jaw is arranged on the chuck moving part, and the moving jaw is located directly below the fixed jaw. When the piston rod of the cylinder retracts, the chuck moving part is driven to drive the moving jaw to move toward the fixed jaw, thereby clamping the cloth between the two jaws.

[0008] As a supplement to the technical solution of the present invention, the rotary cloth tearing chuck also includes a chuck guide rod, the upper end of the chuck guide rod is arranged on the chuck fixing part, and the chuck moving part is provided with a guide sleeve for the chuck guide rod to pass through, and the lower part of the chuck guide rod is located in the guide sleeve on the chuck moving part, and the chuck guide rod is used to provide motion guidance for the movement of the chuck moving part.

[0009] As a supplement to the technical solution of the present invention, it also includes a hollow rotating platform, a chuck rotation drive mechanism, and a cloth-tearing chuck flange; the hollow rotating platform and the chuck rotation drive mechanism are both arranged on the chuck bracket, and the hollow rotating platform is connected to the chuck fixing part through the cloth-tearing chuck flange; the chuck rotation drive mechanism includes a rotating motor, which is connected to the hollow rotating platform to drive the cloth-tearing chuck flange to rotate, thereby driving the chuck fixing part to rotate.

[0010] As a supplement to the technical solution of the present invention, the upper edge of the chuck fixing part is an arc-shaped structure, and the lower edge of the chuck movable part is an arc-shaped structure. When the piston rod of the cylinder retracts so that the fixed jaw and the movable jaw are in a state of clamping the cloth, the chuck fixing part and the chuck movable part are combined to make the outer periphery of the rotary cloth tearing chuck a circular structure.

[0011] As a supplement to the technical solution of the present invention, when the chuck fixing portion and the chuck moving portion are in a combined state, the following formula is satisfied:

[0012] πD≥B

[0013] In the above formula, D is the diameter of the rotary tearing chuck, and B is the width of the fabric;

[0014] The rotation speed of the rotary cloth tearing chuck and the traverse speed of the rotary cloth tearing chuck satisfy the following relationship:

[0015] V 转 =V 横

[0016] In the above formula, V 转 V is the linear velocity of the outer periphery of the rotating cloth tearing chuck, 横 is the traverse speed of the rotating cloth tearing chuck.

[0017] As a supplement to the technical solution of the present invention, it also includes a distance measuring sensor and an edge finding sensor. The distance measuring sensor is arranged on the bracket of the linear walking bracket, and the edge finding sensor is arranged on the flange of the cloth tearing chuck. It can monitor the edge position of the cloth and enable the rotating cloth tearing chuck to clamp the cloth smoothly.

[0018] The present invention also discloses a method for using the above-mentioned rotary cloth tearing device for flat-width flexible cloth, which comprises the following steps:

[0019] S1. The drive motor rotates, causing the rotating tearing chuck to drive the fixed jaw and the movable jaw to move. When the edge-finding sensor detects the edge of the fabric, the drive motor stops rotating.

[0020] S2. The cylinder drives its piston rod to retract so that the fixed jaw and the movable jaw can clamp the fabric;

[0021] S3. The chuck rotation drive mechanism drives the rotary cloth tearing chuck to rotate, and at the same time the linear travel drive mechanism drives the chuck bracket to drive the rotary cloth tearing chuck to move laterally together, so that the rotation speed of the rotary cloth tearing chuck is the same as the lateral movement speed of the rotary cloth tearing chuck;

[0022] S4. After the cloth tearing is completed, the cylinder drives its piston rod to extend, so that the movable jaw moves away from the fixed jaw, and the cloth falls freely. The chuck rotation drive mechanism and the linear travel drive work together to reset the rotary cloth tearing chuck.

[0023] Beneficial Effects: The present invention utilizes a rotating cloth-tearing chuck in conjunction with a linear travel support and a linear travel drive mechanism to achieve automated cloth-tearing functionality. In another aspect of the present invention, by defining the rotating cloth-tearing chuck as a circular shape and defining the relationship between its diameter and the width of the fabric, the fabric is automatically removed after the rotating cloth-tearing chuck tears the fabric. In another aspect of the present invention, the method for using the rotating cloth-tearing device ensures that a constant cloth-tearing angle is maintained during cloth-tearing, ensuring effective cloth-tearing performance.

[0031] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] like Figures 1 to 5 The figure shows a device for tearing open the seams of a flexible fabric, which is used to replace manual labor and realize mechanical automation to tear the seams of the fabric, thereby improving work efficiency. The device comprises a rotating tearing chuck 1, a linear travel bracket, and a linear travel drive mechanism.

[0033] The linear travel support includes a support 2, a rack 3, and a guide rail 4. The rack 3 and the guide rail 4 are both arranged on the travel support 2, and the length directions of the rack 3 and the guide rail 4 are set to be parallel.

[0034] The linear travel drive mechanism includes a drive motor 5, a gear, and a chuck bracket 6. The chuck bracket 6 is arranged on the guide rail 4 of the linear travel bracket, and a slider that matches the guide rail 4 is provided on the chuck bracket 6 so that the chuck bracket 6 can slide freely on the guide rail 4.

[0035] The driving motor 5 is arranged on the chuck bracket 6, and the gear is arranged on the rotating shaft of the motor and meshes with the rack 3 of the linear travel bracket, so that when the motor drives the gear to rotate, the chuck bracket 6 is driven to slide along the slide rail.

[0036] The rotary cloth-tearing chuck 1 includes a chuck fixing portion 7 , a chuck moving portion 8 , a cylinder 9 , a fixed jaw 10 , and a moving jaw 11 .

[0037] The chuck fixing portion 7 is arranged on the chuck bracket 6 and can move on the walking bracket 2 together with the chuck bracket 6 .

[0038] The cylinder 9 is fixed on the chuck fixing part 7. The chuck moving part 8 is located below the chuck fixing part 7, and the end of the piston rod of the cylinder 9 is connected to the chuck moving part 8. The chuck moving part 8 is driven away from and close to the chuck fixing part 7 by extending and retracting the piston rod of the cylinder 9.

[0039] The fixed jaw 10 is mounted on the chuck fixed portion 7, and the movable jaw 11 is mounted on the chuck movable portion 8, with the movable jaw 11 positioned directly below the fixed jaw 10. When the piston rod of the air cylinder 9 retracts, the movable portion 8 drives the movable jaw 11 toward the fixed jaw 10, clamping the fabric between the two jaws. Once clamping is complete, the travel drive mechanism drives the rotary tearing chuck 1 along the travel support 2 to tear the fabric.

[0040] As a preferred technical solution of the present invention, the rotary cloth tearing chuck 1 also includes a chuck guide rod 12, the upper end of the chuck guide rod 12 is arranged on the chuck fixing part 7, and the chuck moving part 8 is provided with a guide sleeve for the chuck guide rod 12 to pass through, so that the lower part of the chuck guide rod 12 is located in the guide sleeve on the chuck moving part 8. The chuck guide rod 12 is used to provide motion guidance for the movement of the chuck moving part 8, and at the same time acts as a support to bear the load provided by the chuck moving part during the rotation process, thereby improving the stability of the overall structure.

[0041] As a preferred technical solution of the present invention, it also includes a hollow rotating platform 13, a chuck rotation drive mechanism 14, and a cloth tearing chuck flange 15. The hollow rotating platform 13 and the chuck rotation drive mechanism 14 are both arranged on the chuck bracket 6. The hollow rotating platform 13 is fixedly connected to the chuck fixing part 7 through the cloth tearing chuck flange 15. The rotation of the hollow rotating platform 13 can drive the chuck fixing part 7 to rotate together.

[0042] The rotation drive mechanism includes a rotation motor, which is connected to a gear in the hollow rotation platform 13 to drive the hollow rotation platform 13 to rotate.

[0043] By setting the hollow rotating platform 13 and the chuck rotating drive mechanism 14, the rotatable function of the rotary cloth-tearing chuck 1 is realized. Under the condition of a certain width of the cloth seam head, the rotation and transverse movement functions of the rotary cloth-tearing chuck 1 are realized. During the rotary cloth-tearing process, the cloth seam head can be wrapped around the rotary cloth-tearing chuck 1.

[0044] The rotary cloth-tearing chuck 1 can realize the cloth-tearing function only by lateral movement. Alternatively, a combination of rotation and lateral movement can be adopted to reduce the lateral movement distance.

[0045] As a preferred technical solution of the present invention, the upper edge of the chuck fixing part 7 is an arc-shaped structure, and the lower edge of the chuck movable part 8 is an arc-shaped structure. When the piston rod of the cylinder 9 retracts so that the fixed jaw 10 and the movable jaw 11 are in a state of clamping the cloth, the chuck fixing part 7 and the chuck movable part 8 are merged, so that the outer periphery of the rotary cloth tearing chuck 1 has a circular structure.

[0046] Under this structural design, the rotary cloth tearing chuck 1 adopts a combination of rotation and transverse movement during the cloth tearing process. After the fixed jaw 10 and the movable jaw 11 complete the cloth clamping state, the rotary cloth tearing chuck 1 rotates and moves transversely at the same time to tear the seam end of the cloth.

[0047] As a supplement to the above technical solution, when the clamp fixing portion 7 and the clamp moving portion 8 are in a combined state, the relationship between the diameter D of the rotary cloth tearing clamp 1 and the cloth width B satisfies:

[0048] πD≥B

[0049] After the cloth tearing is completed, the cloth wrapped around the rotary cloth tearing chuck 1 is less than one circle. When the movable jaw 11 is released, the cloth can fall off freely from the rotary cloth tearing chuck 1.

[0050] like Figure 5 As shown, in this process, the rotation speed V of the rotating cloth tearing chuck 1 is set 转 The traverse speed V of the rotating tearing chuck 1 横 The same, so that the lateral movement distance of the rotary cloth-tearing chuck 1 is the same as the cloth width B. The cloth width is the width of the cloth. During the cloth-tearing process, the cloth is wrapped around the outer surface of the rotary cloth-tearing chuck 1. Through the above-mentioned setting, the cloth-tearing is completed at a constant angle α during the cloth-tearing process, ensuring the stability of the cloth-tearing while reducing the lateral movement distance of the rotary cloth-tearing chuck 1, saving equipment production costs while improving space utilization. Compared with the rotary cloth-tearing chuck 1 that only moves horizontally to tear the cloth, its lateral movement distance is 2B, that is, the length of the guide rail 4 on the straight-line travel bracket needs to be greater than 2B, and the cloth-tearing angle continues to decrease during the lateral movement, which seriously affects the stability of the cloth-tearing.

[0051] As a preferred technical solution of the present invention, a distance measuring sensor is further included. The distance measuring sensor is arranged on the bracket 2 of the linear travel bracket and is used to monitor the position of the chuck bracket 6 on the linear travel bracket.

[0052] As a preferred technical solution of the present invention, an edge-finding sensor is also included. The edge-finding sensor is actually a photoelectric sensor. It is installed on the tear-off chuck flange 15 and can monitor the fabric. When the tear-off chuck is rotated toward the fabric, the tear-off chuck flange 15 approaches the fabric and detects changes in the optical signal, thereby identifying the fabric edge.

[0053] The present invention also discloses a method for using the above-mentioned rotary cloth tearing device for flat-width flexible cloth, which comprises the following steps:

[0054] S1. The drive motor 5 rotates, so that the rotating cloth tearing chuck 1 drives the fixed jaw 10 and the movable jaw 11 to move. When the edge sensor detects the edge of the fabric, the drive motor 5 stops rotating;

[0055] S2. The cylinder 9 drives its piston rod to retract so that the fixed jaw 10 and the movable jaw 11 clamp the fabric, and the edges of the fabric on both sides of the fixed jaw 10 and the movable jaw 11 are cut so that the fixed jaw 10 and the movable jaw 11 can smoothly tear off the fabric;

[0056] S3. The chuck rotation drive mechanism 14 drives the rotary cloth tearing chuck 1 to rotate, and at the same time the linear travel drive mechanism drives the chuck bracket 6 to drive the rotary cloth tearing chuck 1 to move laterally. The rotation speed of the rotary cloth tearing chuck 1 and the lateral movement speed of the rotary cloth tearing chuck 1 satisfy the following relationship:

[0057] V 转 =V 横

[0058] In the above formula, V 转 V is the linear velocity of the outer periphery of the rotating cloth tearing chuck 1, 横 is the traverse speed of the rotating cloth tearing chuck 1;

[0059] S4. After the cloth tearing is completed, the cylinder 9 drives its piston rod to extend, so that the movable jaw 11 moves away from the fixed jaw 10, and the cloth falls freely. The chuck rotation drive mechanism 14 and the linear travel drive work together to reset the rotary cloth tearing chuck 1.

[0060] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
