Description

Technical Field

[0001] This application relates to the field of finished yarn transportation technology, and in particular to a stacking device at the tail of a straight twisting machine. Background Technology

[0002] Automated palletizing devices, as crucial equipment in modern industrial automated production lines, bring significant benefits to manufacturing, logistics, and warehousing management sectors due to their efficient material handling capabilities, precise palletizing accuracy, and powerful intelligent features. However, with the continuous development of automation technology, the disadvantages of automated palletizing devices in terms of size and floor space have gradually become apparent, becoming one of the key factors restricting their further popularization and application.

[0003] Chinese Patent Publication No. CN119429716A discloses an automated palletizing device, which includes a pallet collection and dispatch module, a pallet centering module, a gripping module, and a pallet turning module. The pallet collection and dispatch module dispatches collected pallets to a conveyor line. The pallet centering module centers each pallet dispatched by the pallet collection and dispatch module on the conveyor line. The gripping module grips goods onto the centered pallet. The pallet turning module turns the pallet carrying goods in the direction of transport. The turned pallet is then transported to a shaping table, where the goods are adjusted for placement on the pallet. This invention features a compact design for each process module, a small overall footprint, flexible operation, and high transport efficiency.

[0004] Regarding the aforementioned technologies, in the prior art, palletizing devices use a conveyor to transport goods that have been pre-lifted onto a conveyor belt, and then use a robotic arm to place the goods on a forming table to achieve neatness of the goods. However, in the prior art, the palletizing devices are set up in a designated location, and the goods need to be transported manually using a crane beforehand, which increases labor costs for workers, increases the goods transportation time, and reduces the goods handling efficiency of the palletizing device. Summary of the Invention

[0005] In order to improve the cargo handling efficiency of the palletizing device, this application provides a straight twisting machine tail palletizing device.

[0006] The technical solution provided in this application for the tail stacking device of a straight twisting machine is as follows:

[0007] A stacking device for the tail of a straight twisting machine includes a moving trolley that moves at the ends of several straight twisting machines. The ends of the straight twisting machines are provided with moving tracks. The moving trolleys move on the moving tracks and are equipped with robotic arms. The ends of the moving tracks are provided with several transfer frames for temporarily placing finished yarns. Both the moving trolleys and the transfer frames are provided with conveying components for conveying finished yarns.

[0008] By adopting the above technical solution, during transportation, the straight twisting machine conveys the finished yarn to the gripping station. Then, a mobile cart moves to the corresponding straight twisting machine position, and a robotic arm places the finished yarn onto the mobile cart until it forms a stack of yarn of the specified size. The stack is then moved to a transfer rack, where two conveying components work together to transport it. Workers then use conveying tools to move the stack away, thus realizing the transportation of the finished yarn. By using a mobile cart to grip and convey the finished yarn, forming stacks of yarn of the specified size on the mobile cart, and finally transporting the stacks to the transfer rack, this method, compared to existing technologies, replaces workers in handling the finished yarn, shortening the transportation time, reducing the labor intensity of workers, and improving the yarn transportation efficiency of the palletizing device. Furthermore, using only a few transfer racks for temporary storage of the yarn stacks reduces the space occupied within the factory, making internal traffic more convenient and smoother, and reducing the occurrence of accidents.

[0009] Optionally, the mobile vehicle is provided with a placement station and a stacking station. The placement station is provided with several layers of boards. A set of conveying components is provided at both the placement station and the stacking station. The conveying component at the stacking station is provided with a base and a positioning block. A positioning hole is provided at the middle position of the board layer. The robotic arm is located between the placement station and the stacking station.

[0010] By adopting the above technical solution, during the conveying process, stacked shelves are placed at the placement station on the mobile vehicle, a base is placed at the stacking station, the shelves are placed on the base, and a specified number of finished yarns are placed on each shelf. The yarns are stacked layer by layer until a yarn stack of a specified specification is formed. Finally, the yarn stack is conveyed to the transfer frame to achieve the effect of collecting and conveying finished yarns.

[0011] Optionally, a stop is provided at the end of the movable guide rail, and an anti-collision block is connected on the movable vehicle at the position corresponding to the stop. The anti-collision block is made of rubber material.

[0012] By adopting the above technical solution, the stop is used to prevent the moving car from derailing, and the anti-collision block is used to buffer the impact of the moving car on the stop, reducing the possibility of damage to the moving car.

[0013] Optionally, the conveying assembly includes a conveying chain, conveying sprockets, and a conveying motor. Several sets of conveying sprockets are rotatably connected on the mobile vehicle, with two sprockets in each set. The conveying chain is sleeved between the sets of conveying sprockets and abuts against the surface of the mobile vehicle. The conveying motor is installed inside the mobile vehicle. A conveying shaft connects the several sets of conveying sprockets, and the conveying motor is connected to the conveying shaft via a chain. A deceleration sensor and a stop sensor are installed at the stacking station. The stop sensor is located between the deceleration sensor and the straight twisting machine. The conveying motor, the deceleration sensor, and the stop sensor are all electrically connected to the internal control system of the mobile vehicle.

[0014] By adopting the above technical solution, when the new base is transported to the mobile vehicle, the conveyor motor is started, driving the conveyor sprocket to rotate, the conveyor chain to move, and thus the base to move. When the base reaches the sensing end of the deceleration sensor, the deceleration sensor sends an electrical signal to the control system inside the mobile vehicle, causing the control system to reduce the output power of the conveyor motor, thus slowing down the conveyor chain until the base moves to the sensing end of the stop sensor. At this point, the control system stops the conveyor motor, and the base stops moving. By setting up deceleration and stop sensors, the possibility of the base continuing to move due to inertia when it stops is reduced.

[0015] Optionally, a stop is provided at the end of the transfer frame away from the moving track, and a limiting frame for positioning the base is provided on both sides of the transfer frame.

[0016] By adopting the above technical solution, when the wire stack moves to the transfer frame by setting up a stop, the conveying component continuously moves the wire stack until the base at the bottom of the wire stack touches the stop to prevent the wire stack from moving further. At the same time, the limiting frame restricts the base from shifting. Then, the staff can use a forklift to lift the base to achieve the effect of transferring and transporting the wire stack.

[0017] Optionally, the limiting frame includes a fixed frame, a stop, a connecting rod, and locking bolts. Two fixed frames are connected to both sides of the transfer frame. The connecting rods are horizontally inserted through the fixed frames. The stop is connected between the two connecting rods. Two locking bolts are threaded onto the connecting rods. The end of the fixed frame is located between the two locking bolts.

[0018] By adopting the above technical solution, adjusting the position of the connecting rod on the fixed frame and tightening it with locking bolts, the position of the stop frame can be adjusted, which is suitable for the limiting effect of bases of different sizes.

[0019] Optionally, a storage rack is provided on one side of the transfer frame, and a set of conveying components is also provided at the bottom of the storage rack. The storage rack is provided with a lifting component and a support component for supporting the base. The lifting component includes a lifting motor, a worm gear screw jack, and a lifting frame. Several worm gear screw jacks are installed on the storage rack, and the lifting frame is connected between the lifting ends of two adjacent worm gear screw jacks. The lifting motor is installed on the storage rack and is driven by several worm gear screw jacks through a turbine box. The height of the support component is higher than the height of the lifting component.

[0020] By adopting the above technical solution, the storage rack is used to store bases. When stacking, a base is placed on the conveying component, the lifting motor is started, and several worm gear screw jacks are synchronously driven through the turbine box to raise the lifting frame, which in turn raises the base to a specified height. The supporting component lifts the base, and the lifting frame returns to its original position to place the second base. When the second base rises, it lifts the first base, and the supporting component returns to its original position. This process is repeated to store the bases. When in use, when a stack of wires is conveyed to the transfer rack, the stacking station is aligned with the storage rack. The supporting component lifts the second base at the bottom, and the conveying component on the storage rack pushes the lowest base into the stacking station. At this point, the lifting component can be used to lower the base by one layer, enabling the mobile cart to retrieve the base.

[0021] Optionally, a set of the support assembly is provided on both sides of the storage rack. The support assembly includes a fixed plate, a push cylinder, and a support plate. The fixed plate is connected to the storage rack. Several fixed cylinders are horizontally connected to the fixed plate. Sliding rods are slidably fitted inside the fixed cylinders. The support plate is connected between the several sliding rods. Limiting blocks are connected to both ends of the support plate. The push cylinder is connected to the fixed plate, and its output shaft is connected to the support plate.

[0022] By adopting the above technical solution, when the first base reaches the designated height, the push cylinder is activated, which moves the support plate to the designated position. At this time, the first base abuts against the limiting blocks on both sides, the lifting frame returns to its original position, and the first base is lifted by the support plates on both sides, thus achieving the effect of lifting the base.

[0023] Optionally, a stop bar is connected to the end of the storage rack away from the moving track, and several limiting plates are installed on both sides of the storage rack, with the base stacked between the stop bar and the limiting plates on both sides.

[0024] By adopting the above technical solution, the stop bar cooperates with the limiting plates on both sides to restrict the three degrees of freedom of the base, and in conjunction with the conveying components, the effect of positioning and storing the base is achieved.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. During transportation, the straight twisting machine conveys the finished yarn to the gripping station. Then, a mobile cart moves to the corresponding straight twisting machine position, and a robotic arm places the finished yarn onto the cart until it forms a stack of yarn of the specified size. The stack is then moved to a transfer rack, where two conveying components work together to transport it. Workers then use conveying tools to move the stack away, thus achieving the transportation of the finished yarn. By using a mobile cart to grip and convey the finished yarn, forming stacks of the specified size on the cart, and finally transporting the stacks to the transfer rack, this method, compared to existing technologies, replaces workers in handling the finished yarn, shortening the transportation time, reducing the labor intensity of workers, and improving the yarn transportation efficiency of the palletizing device. Furthermore, using only a few transfer racks for temporary storage of the yarn stacks reduces the required factory floor space, making internal factory traffic more convenient and smoother, and reducing the occurrence of accidents.

[0027] 2. The storage rack is used to store bases. When stacking, one base is placed on the conveyor assembly, the lifting motor is started, and several worm gear screw jacks are synchronously driven through the turbine box to raise the lifting rack, which in turn raises the base to the designated height. The support assembly lifts the base, and the lifting rack returns to its original position to place the second base. When the second base rises, it lifts the first base, and the support assembly returns to its original position, and so on, to store the bases. When in use, when a stack of wire is conveyed to the transfer rack, the stacking station is aligned with the storage rack. The support assembly lifts the second base at the bottom, and the conveyor assembly on the storage rack pushes the lowest base into the stacking station. At this time, the lifting assembly can be used to lower the base by one layer, so that the mobile cart can retrieve the base. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0039] This application discloses a tail stacking device for a straight twisting machine. (Refer to...) Figure 1 and Figure 2 The tail stacking device of the straight twisting machine includes a moving track 1 located at the end of the straight twisting machine 01. In this embodiment, six straight twisting machines 01 are provided. The straight twisting machine 01 is equipped with a conveying channel and a gripping station, and has built-in radio components. A moving cart 2 is provided on the moving track 1 and rolls on the moving track 1. A stop 11 is installed at the end of the moving track 1 to prevent the moving cart 2 from derailing. A collision protection block 21 is fixedly connected to the end of the moving cart 2 at the position corresponding to the stop 11. The collision protection block 21 is made of rubber material and is used to buffer the impact force of the moving cart 2.

[0040] Reference Figure 3 and Figure 4The mobile vehicle 2 is equipped with a placement station 22 and a stacking station 23. Several layers of boards 02 are stacked at the placement station 22. A conveying assembly 3 is located at the stacking station 23. The conveying assembly 3 includes a conveying chain 31, conveying sprockets 32, and a conveying motor 33. Several sets of conveying sprockets 32 are rotatably connected at the stacking station 23. In this embodiment, three sets are used as an example, with two conveying sprockets 32 in each set. The conveying chain 31 is fitted between a set of conveying sprockets 32, and a conveying shaft is fixedly connected to each set of conveying sprockets 32. The conveying motor 33 is installed inside the mobile vehicle 2 and is driven by the chain and the conveying shaft.

[0041] Reference Figure 4 and Figure 5 The mobile vehicle 2 is equipped with a deceleration sensor 24 and a stop sensor 25. Both the deceleration sensor 24 and the stop sensor 25 are proximity sensors, and their sensing ends face upwards towards the conveyor sprocket 32. A base 03 is provided at the stacking station 23, and the base 03 is placed on the conveyor chain 31. A positioning block is fixedly connected to the base 03, and a positioning hole is provided in the middle of the shelf 02. A robotic arm 26 is installed on the mobile vehicle 2 at the position between the placement station 22 and the stacking station 23. The robotic arm 26, the conveyor motor 33, the deceleration sensor 24, and the stop sensor 25 are all electrically connected to the internal control system of the mobile vehicle 2.

[0042] During the gripping process, the straight twisting machine 01 moves the processed yarn to the gripping station through the conveyor channel and sends a signal to the moving vehicle 2 via radio. The moving vehicle 2 moves to the position of the straight twisting machine 01, first gripping the layer plate 02 and placing it on the base 03 through the robotic arm 26. The positioning block enters the positioning hole, and then gripping the yarn and placing it in the designated position on the layer plate 02. This continues until a specified number of yarns are placed on the layer plate 02. Then, another layer plate 02 is gripped and placed on the yarn, and so on. After stacking a specified number of layers of yarn, a yarn stack of a specified specification is formed.

[0043] Reference Figure 1 and Figure 6 Several transfer frames 4 are provided at the end of the moving track 1. In this embodiment, four transfer frames 4 are provided. The four transfer frames 4 are distributed along the length of the moving track 1. One of the transfer frames 4 is used to place the shelf 02. A set of conveying components 3 is also provided on the transfer frames 4. The installation method is the same as that of the conveying components 3 at the stacking station 23.

[0044] Reference Figure 6 and Figure 7A stop block 41 is fixedly connected to the end of the transfer frame 4 furthest from the moving track 1. Limiting frames 42 are provided on both sides of the transfer frame 4. Each limiting frame 42 includes a fixed frame 421, a stop block 422, a connecting rod 423, and locking bolts 424. The fixed frame 421 is L-shaped, and two fixed frames 421 are bolted to the side wall of the transfer frame 4. The connecting rod 423 passes through the end of the fixed frame 421. The stop block 422 is fixedly connected between the ends of the two connecting rods 423. Two locking bolts 424 are threaded onto the connecting rods 423, and the end of the fixed frame 421 is located between the two locking bolts 424.

[0045] When restricting, the distance between the two side stops 422 is adjusted by adjusting the relative position between the connecting rod 423 and the fixed frame 421, and the stop frame 422 is locked with the locking bolt 424, so as to achieve the effect of restricting the base 03 of different sizes.

[0046] Reference Figure 1 and Figure 8 A storage rack 5 is provided on one side of the transfer frame 4, and a set of conveying components 3 is also provided at the bottom of the storage rack 5. The component installation method of the conveying components 3 can refer to the conveying components 3 at the stacking station 23. Several baffles 51 are fixedly connected to the end of the storage rack 5 away from the moving track 1. Limiting plates 52 are installed on both sides of the storage rack 5. The cooperation of the baffles 51 and the limiting plates 52 is used to limit the base 03.

[0047] Referring to Figure 9, a lifting assembly 6 is provided on the storage shelf 5. The lifting assembly 6 includes a lifting motor 61, a worm gear screw jack 62, and a lifting frame 63. Several worm gear screw jacks 62 are installed on the storage shelf 5; in this embodiment, four are used as an example. The lifting frame 63 is fixedly connected to the lifting ends of two adjacent worm gear screw jacks 62. The lifting motor 61 is installed on the storage shelf 5, and several turbine housings are also installed on the storage shelf 5. The output shaft of the lifting motor 61 is driven by the worm gear screw jack 62 through the turbine housings.

[0048] Reference Figure 9 The storage rack 5 has support components 7 on both sides. Each support component 7 includes a fixed plate 71, a push cylinder 72, and a support plate 73. The fixed plate 71 is bolted to the storage rack 5. Several fixed cylinders 711 are fixedly connected to the fixed plate 71. In this embodiment, two cylinders are used as an example. The height of each fixed cylinder 711 is higher than the height of the lifting frame 63 when it reaches its highest point. A sliding rod 731 is slidably fitted inside each fixed cylinder 711. The support plate 73 is bolted between two sliding rods 731. The push cylinder 72 is mounted on the fixed plate 71, and its output shaft is fixedly connected to the support plate 73.

[0049] When storing base 03, the first base 03 is placed on the conveyor chain 31. The lifting motor 61 is started, causing the worm gear screw jack 62 to raise the lifting frame 63, which in turn raises the first base 03 to the designated height. Then, the push cylinder 72 is started, which moves the support plate 73. The lifting frame 63 returns to its original position, and the first base 03 is placed on the support plate 73. The second base 03 is then placed on the conveyor chain 31. When the second base 03 rises, it lifts the first base 03. During this process, the support plate 73 returns to its original position. This process is repeated to stack the bases 03 for storage. When in use, the moving cart 2 moves until the stacking station 23 is aligned with the storage rack 5. The support component 7 lifts the bottom second base 03, and the conveyor component 3 moves the lowest base 03. When the bottom base 03 is transported to the moving cart 2, the lifting component 6 lifts the bottom second base 03. This process is repeated to lower the bases 03 on the storage rack 5 by one layer.

[0050] The implementation principle of the tail stacking device of a straight twisting machine according to an embodiment of this application is as follows: When the straight twisting machine 01 transports the processed finished yarn to the gripping station, it sends a signal to the moving vehicle 2. The moving vehicle 2 moves to the straight twisting machine 01, first uses the robotic arm 26 to grip the layer plate 02 and place it on the base 03, then grips the finished yarn and places it on the layer plate 02 until the finished yarn on the layer plate 02 reaches a specified quantity, then grips the layer plate 02 and places it on the finished yarn, and so on, stacking layers until a yarn stack of a specified specification is formed. The moving vehicle 2 is then moved to the transfer frame 4, the conveyor motor 33 is started, the conveyor chain 31 moves, and the yarn stack is moved to the transfer frame 4. The operator can then operate the forklift to transport the yarn stack to another location, and then move it to the storage rack 5, and transport the bottom base 03 to the moving vehicle 2. The above steps are repeated to grip the finished yarn, realizing the effect of automated gripping, forming yarn stacks, and transporting yarn stacks.

[0051] Finished yarn is picked up and transported by a mobile cart 2, forming yarn stacks of specified specifications on the cart. Finally, the yarn stacks are transported to transfer racks 4. Compared to existing technologies, this method allows the mobile cart 2 to replace workers in handling the finished yarn, shortening the transport time, reducing the labor intensity of workers, and improving the yarn transport efficiency of the palletizing device. Furthermore, only a few transfer racks 4 are needed for temporary storage of the yarn stacks, occupying less internal factory space, making internal factory traffic more convenient and smooth, and reducing the occurrence of accidents.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
