Description

Technical Field

[0001] This invention relates to the field of spinning technology, and in particular to a long filament finished product transfer device that prevents it from falling off. Background Technology

[0002] In existing technologies, when transferring finished fiber filaments in a yarn cake, an intelligent doffing robot is generally used to transfer the paper roll with the yarn cake wound from the spinning equipment winding machine to the hanging rack. For example, in the yarn cake transfer device of the existing technology, when in use, the vehicle body moves to the discharge port of the winding machine and aligns the yarn cake tube inside the vehicle body with the yarn cake tube in the discharge port of the winding machine. The winding machine pushes the yarn cake from the yarn cake tube in the discharge port to the yarn cake tube on the vehicle body. After the yarn cake is pushed, the vehicle body transports the yarn cake to the hanging rack for hanging. In order to prevent the yarn cake on the yarn cake tube from falling out of the yarn cake tube, the opening is generally closed by a roller shutter door set at the opening of the vehicle body to prevent the yarn cake from falling out of the yarn cake tube. However, the actual use effect is not good, because the yarn cakes are generally transferred in multiple strings. Relying solely on the roller shutter door to prevent falling out cannot prevent multiple yarn cakes from moving axially along the yarn cake tube, which can easily cause tangled yarns and also hinder the subsequent transfer to the hanging rack.

[0003] In conclusion, it is necessary to improve and optimize the anti-drop structure of the filament finished product transfer device. Summary of the Invention

The front wall of the vehicle body is provided with a collection port. The filament bobbin is mounted inside the vehicle body via the pushing rod device, and the filament bobbin can be pushed out of the collection port by the pushing rod device. The outer wall of the filament bobbin is provided with a rectangular hole that extends through both the inside and outside. The inner side wall of the filament bobbin is provided with a driving rod via a driving structure. The driving rod and driving structure are arranged sequentially in a front-to-back configuration on the inner side wall of the filament bobbin. The outer wall of the driving rod facing the rectangular hole is provided with a groove of equal length to the length of the driving rod. A movable plate is slidably connected to the inner side wall of the groove. A linkage structure is provided between the movable plate and the groove. A top block is provided on the side of the movable plate away from the driving rod. The outer wall of the top block is slidably connected to the inner side wall of the rectangular hole. A reset structure for resetting is provided between the movable plate and the inner side wall of the filament bobbin.

The extension shaft of the reciprocating linear driver passes through the inner wall of the right set of two fixing plates and extends to its front side. The end of the extension shaft of the reciprocating linear driver is fixedly connected to the rear end of the drive rod.

[0008] As a further description of the above technical solution:

[0009] The guiding structure includes a guide post and a guide ring. The guide ring is fixedly connected to the inner wall of the yarn drum and close to the end of the yarn drum. The inner wall of the guide ring is provided with a guide hole that runs through the front and back. The axis of the guide hole is collinear with the axis of the yarn drum. The guide post is fixedly connected to the front end of the drive rod. The end of the guide post away from the drive rod is slidably connected to the inner wall of the guide hole.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the guide post is provided with a buffer pad for cushioning, and the buffer pad is disposed between the drive rod and the guide ring.

[0012] As a further description of the above technical solution:

[0013] The reset structure includes two sets of springs. The movable plate has two sets of mounting holes on the side away from the drive rod.

[0016] The present invention has the following beneficial effects:

[0017] Compared with existing technologies, this anti-drop filament finished product transfer device, in its initial state, has the reciprocating linear drive extension shaft extended, and the linkage block located on the inner wall of the arc groove. After the filament cake is delivered from the winding machine to the outer wall of the filament drum, the reciprocating linear drive extension shaft retracts, driving the drive rod to move axially backward, thereby withdrawing the linkage block from the arc groove into the slide groove. This moves the movable plate away from the center of the filament drum, causing the top block to extend from the rectangular hole to the outside of the filament drum, thus holding the paper roll of the wound filament cake in place and preventing the problem of falling off and shifting during transportation. After being transported to the vicinity of the filament hanging frame, the extension of the reciprocating linear drive extension shaft drives the drive rod forward, and the movable plate, through the elastic force of the spring, drives the linkage block back into the arc groove, thereby causing the top block to lose its clamping force on the paper roll, facilitating the pushing of the filament cake. It is very convenient to use and has a simple and effective structure. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 5 The present invention provides a long filament finished product transfer device to prevent falling: including a car body 1, a filament spool 3, and a traveling device, a positioning device, a cake pushing device, and a push rod device installed on the car body 1. The front wall of the car body 1 is provided with a collection port 2. The filament spool 3 is installed inside the car body 1 through the push rod device and can be pushed out of the collection port 2 by the push rod device. During operation, the car body 1 moves to the vicinity of the corresponding winding machine through the traveling device, and the position is determined by the positioning device. The push rod device removes the filament spool 3. The discharge device on the winding machine pushes the filament cake with the wound long filament finished product onto the outer wall of the filament spool 3. The push rod device then drives the filament spool 3 back into the car body 1. The car body 1 travels to the filament hanging frame through the traveling device, and the filament cake is pushed to the filament hanging frame for storage by the cake pushing device, thus completing the transfer action.

[0027] The outer wall of the wire drum 3 is provided with a rectangular hole 10 that runs through the inside and outside. The inner wall of the wire drum 3 is provided with a drive rod 4 through a drive structure. The drive rod 4 and the drive structure are arranged in a front-to-back distribution on the inner wall of the wire drum 3. The drive structure includes a reciprocating linear driver 16 and two sets of fixing plates 15. The two sets of fixing plates 15 are arranged in a front-to-back distribution and are fixedly connected to the inner wall of the wire drum 3 and are both located behind the drive rod 4. The reciprocating linear driver 16 is fixedly connected between the two sets of fixing plates 15. The extension shaft of the reciprocating linear driver 16 passes through the inner wall of the right set of the two sets of fixing plates 15 and extends to its front side. The end of the extension shaft of the reciprocating linear driver 16 is fixedly connected to the rear end of the drive rod 4. The extension and retraction of the extension shaft of the reciprocating linear driver 16 drives the drive rod 4 to move back and forth along the axial direction of the wire drum 3.

[0028] A groove 5 of equal length to the drive rod 4 is provided on the outer wall of the side facing the rectangular hole 10. A movable plate 11 is slidably connected to the inner wall of the groove 5. A linkage structure is provided between the movable plate 11 and the groove 5. The linkage structure includes a linkage block 13 and an arc groove 6. The arc groove 6 is located on the lower inner wall of the groove 5 and its width is the same as the width of the groove 5. The linkage block 13 is fixedly connected to the side of the movable plate 11 facing the drive rod 4 and is slidably connected to the inner wall of the groove 5. The cross-section of the side of the linkage block 13 away from the movable plate 11 is an arc shape with the same curvature as the arc groove 6. A top block 12 is provided on the side of the movable plate 11 away from the drive rod 4. The outer wall of the top block 12 is slidably connected to the inner wall of the rectangular hole 10. In the initial state, the reciprocating straight... The extension shaft of the linear actuator 16 is in the extended state, and the end of the linkage block 13 away from the movable plate 11 is located inside the arc groove 6. When the reciprocating linear actuator 16 drives the drive rod 4 to retract, the linkage block 13 is moved along the arc of the arc groove 6 to the inner wall of the slide 5. The distance between the lowest point of the inner lower wall of the slide 5 and the inner lower wall of the arc groove 6 relative to the straight direction of the drive rod 4 is two to three millimeters. When the linkage block 13 is located on the inner wall of the arc groove 6, the highest point of the top block 12 is one millimeter lower than the outer opening of the rectangular hole 10. Therefore, when the linkage block 13 moves from the arc groove 6 to the slide 5, the top block 12 is driven to extend from the rectangular hole 10, thereby pressing against the inner wall of the paper tube used for winding the filament through the highest point of the top block 12, forming a clamping force to prevent it from falling off and moving.

[0029] A reset structure for resetting is provided between the movable plate 11 and the inner wall of the wire drum 3. The reset structure includes two sets of springs 14. Two sets of mounting holes 17 are provided on the side of the movable plate 11 away from the drive rod 4. The two sets of mounting holes 17 are located on the front and rear sides of the top block 12, respectively. The two sets of springs 14 are fixedly connected to the inner walls of the two sets of mounting holes 17. The ends of the two sets of springs 14 away from the movable plate 11 abut against the inner wall of the wire drum 3. When the reciprocating linear drive 16 extends its shaft, the arc groove 6 moves back below the linkage block 13. Through the elastic force of the spring 14, the linkage block 13 enters the arc groove 6, thereby causing the top block 12 to retract from the outside of the rectangular hole 10, completing the release of the clamping state.

[0030] The end of the drive rod 4 away from the drive structure is provided with a guide structure for guiding movement on the inner wall of the wire drum 3. The guide structure includes a guide post 7 and a guide ring 9. The guide ring 9 is fixedly connected to the inner wall of the wire drum 3 and close to the end of the wire drum 3. The inner wall of the guide ring 9 is provided with a guide hole that runs through the front and back. The axis of the guide hole is collinear with the axis of the wire drum 3. The guide post 7 is fixedly connected to the front end of the drive rod 4. The end of the guide post 7 away from the drive rod 4 is slidably connected to the inner wall of the guide hole. The guide post 7 and the guide ring 9 are used to support the end of the drive rod 4 away from the reciprocating linear actuator 16 and guide the movement to maintain the stability of the movement.

[0031] The outer wall of the guide column 7 is provided with a buffer pad 8 for buffering. The buffer pad 8 is located between the drive rod 4 and the guide ring 9. The buffer pad 8 is used to prevent the drive rod 4 from directly colliding with the guide ring 9 when the extension shaft of the reciprocating linear drive 16 extends.

[0032] Working principle: During operation, the vehicle body 1 moves to the vicinity of the corresponding winding machine via the traveling device, and the position is determined by the positioning device. The push rod device retracts the yarn drum 3, and the discharge device on the winding machine pushes the yarn cake with the wound filament into the outer wall of the yarn drum 3. The push rod device then drives the yarn drum 3 back into the vehicle body 1. The vehicle body 1 travels to the yarn hanging frame via the traveling device, and the yarn cake is pushed to the yarn hanging frame for storage by the yarn pushing device, completing the transfer action. The extension shaft of the reciprocating linear drive 16 extends and retracts, driving the drive rod 4 to move back and forth along the axial direction of the yarn drum 3. In the initial state, the extension shaft of the reciprocating linear drive 16 is in the extended state, and the end of the linkage block 13 away from the movable plate 11 is located inside the arc groove 6. When the reciprocating linear drive 16 drives the drive rod 4 to retract, the linkage block 13 moves back and forth along the arc groove. The arc of 6 is moved to the inner wall of the slide groove 5. The distance between the lowest point of the inner lower wall of the slide groove 5 and the inner lower wall of the arc groove 6 relative to the straight direction of the drive rod 4 is two to three millimeters. When the linkage block 13 is located on the inner wall of the arc groove 6, the highest point of the top block 12 is one millimeter lower than the outer opening of the rectangular hole 10. Therefore, when the linkage block 13 moves from the arc groove 6 to the slide groove 5, the top block 12 is driven to extend from the rectangular hole 10, thereby pressing against the inner wall of the paper tube used for winding the filament through the highest point of the top block 12, forming a clamping force to prevent it from falling off and moving. When the reciprocating linear drive 16 extends its shaft, the arc groove 6 moves back below the linkage block 13. Through the elastic force of the spring 14, the linkage block 13 enters the arc groove 6, thereby causing the top block 12 to retract from the outside of the rectangular hole 10, completing the release of the clamping state.
