Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically relating to a warp beam transport device. Background Technology

[0002] A warp beam is a cylindrical device in textile machinery used to fix and arrange warp yarns. It is usually composed of a beam tube, a beam head, and other components. During warp knitting, the warp beam is located behind or above the knitting area and is wound with a large number of parallel yarns, similar to the arrangement of warp yarns in woven fabrics.

[0003] In the textile industry, the handling and transfer of warp knitting beams is a crucial link in the production process, especially in multi-story factories where efficient and safe transfer of warp beams between floors is essential. However, traditional material handling methods have the following problems:

[0004] 1. Freight elevators cannot meet transportation needs: The shaft length is too long, making it impossible to use traditional freight elevators for cross-floor transportation.

[0005] 2. Insufficient safety of traditional lifting equipment: Traditional cranes and overhead cranes require large openings in the floor slab for handling, wasting usable space on the second floor. Furthermore, traditional cranes and overhead cranes require manual operation, posing serious safety hazards.

[0006] 3. Low level of automation: The current manual operation and transportation mode cannot achieve automatic docking with AGV handling, resulting in low overall automation level and low efficiency. Utility Model Content

[0007] This utility model discloses a warp beam handling device, which mainly solves the problem that traditional methods of handling and transferring warp knitting warp beams cannot be used to achieve cross-floor transportation using traditional freight elevators.

[0008] To achieve the aforementioned objective, this utility model provides a warp beam transport device, including a main frame, which is divided into a first floor area and a second floor area. A first base is provided at the bottom of the first floor area, and a second base is provided at the bottom of the second floor area. At least one car is provided for lifting and lowering inside the main frame, and a drive mechanism for driving the car to lift and lower is provided at the top of the main frame.

[0009] The drive mechanism is connected to the transmission mechanism to drive the car to perform a reciprocating lifting motion with the upper end of the first base as the starting point and the upper end of the second base as the ending point. The car is symmetrically equipped with at least two telescopic forks for grabbing the warp shaft into the car. Through the lifting drive mechanism and telescopic fork design of the car, the automated handling of the warp shaft from the first floor to the second floor is realized, which significantly improves logistics efficiency and reduces manual intervention.

[0010] Preferably, a sensing mechanism is provided on the top surface of the two forks. The sensing mechanism is either a laser sensor or an ultrasonic sensor. The sensing mechanism detects and determines whether there is any obstruction in the picking direction of the forks. It can detect obstacles in the picking direction of the forks in real time, prevent collision failures, and ensure operational safety.

[0011] Preferably, a fixed seat is fixedly provided on the top of the forks, and a V-shaped fixing groove is provided on the top of the fixed seat. The obtuse angle formed by the inclined limiting plate can prevent the shaft from rolling, optimize the temporary storage space, and reduce the waiting time for handling. A high-speed door for closing the car space is movably provided on one side of the car. The high-speed door can close the car space during the movement of the car, thereby avoiding external interference.

[0012] Preferably, the two sides of the first floor area of ​​the main frame are provided with detection mechanisms for detecting the positional error between the end face of the head at both ends of the shaft and the shaft end. The detection mechanism is also electrically connected to an alarm mechanism. The detection mechanism is used to detect the distance. When the detected distance does not meet the preset value, an alarm is triggered to notify manual handling.

[0013] Preferably, the forks are movably mounted above the adjustment mechanism at the bottom of the car, and the distance between the two forks is adjusted by the adjustment mechanism, thereby enabling the forks to adapt to warp beams of various lengths.

[0014] Preferably, a maintenance room is provided at the top of the main frame, and a dedicated ladder is provided on the side of the main frame. The ladder facilitates manual maintenance, thereby simplifying equipment upkeep and reducing downtime.

[0015] Preferably, both the first-floor and second-floor areas are equipped with operating consoles electrically connected to the drive mechanism, detection mechanism, alarm mechanism, sensing mechanism, and adjustment mechanism. Each operating console is equipped with an operation panel and control buttons. The operating consoles in the first and second-floor areas integrate drive, detection, and alarm functions, and enable one-button operation through the control panel, thereby improving human-machine interaction efficiency.

[0016] Preferably, the transmission mechanism includes a transmission wheel rotatably disposed at the bottom of one side of the main frame, and a transmission belt sleeved on its outer side.

[0017] Preferably, it also includes a buffer rack for placing the warp beams. The top of the buffer rack is symmetrically inclined with at least four limiting plates, so that an obtuse angle is formed between two opposing limiting plates. The obtuse angle formed by the inclined limiting plates can prevent the warp beams from rolling, optimize temporary storage space, reduce handling waiting time, and the obtuse angle can also accommodate a wider range of disc diameters, thereby enhancing applicability.

[0021] S3: After the car rises to the second floor area, the fast door opens, the forks extend from the car and adjust the spacing according to the length of the pan head string. Then the forks lift the pan head string from the buffer rack, and then the forks retract to move the pan head string into the car. The fast door closes, the car descends to the first floor area, the fast door opens again, and the forks extend from the car to move the pan head string to the AGV at the docking position.

[0022] S4: When the lower shaft is being transported, the AGV moves to the docking position and stands by. At the same time, the car descends to the first floor area, the high-speed door opens, the forks extend out of the car and adjust the spacing according to the length of the pan head string. Then the forks lift the pan head string from the buffer rack, and then the forks retract to move the pan head string into the car. The high-speed door closes, and then the car rises to the second floor area and places the pan head string on the buffer rack.

[0040] Implementation method 1:

[0041] Please refer to Figure 1 , Figure 1 This is a side view of Embodiment 1 of the present invention. This embodiment provides a warp beam transport device, including a main frame 10. The main frame 10 is vertically divided into a first floor area and a second floor area. A first base 11 is provided at the bottom of the first floor area, and a second base 12 is provided at the bottom of the second floor area. In this embodiment, two cars 20 are lifted and lowered on the inner side of the main frame 10. Two telescopic forks 21 are symmetrically installed inside the cars 20 for gripping the warp beam.

[0042] In this embodiment, the main frame 10 is a four-column frame, which is made of square tubes, ordinary steel, plates and other materials, and is welded and assembled. It is the main body for installing and supporting the whole machine components.

[0043] Please refer to Figure 2 as well as Figure 5 , Figure 2 This is a front view of Embodiment 1 of the present invention. Figure 5 This is a top view of Embodiment 1 of the present utility model. The top of the main frame 10 is provided with a drive mechanism 31, which drives the car 20 to reciprocate between the upper surface of the first base 11 and the upper surface of the second base 12 through the transmission mechanism.

[0044] The output end of the drive mechanism 31 is provided with a first transmission wheel. The transmission mechanism includes a second transmission wheel located at the bottom of the main frame 10, and a transmission belt sleeved on the outside of the first transmission wheel and the second transmission wheel. The other end of the transmission belt is fixed to the main frame 10. Guide rails are also provided on both sides of the main frame 10. The guide rails correspond to the positioning plates provided on both sides of the car 20 to assist the car 20 in moving smoothly during lifting.

[0045] Please refer to the following: Figure 3 as well as Figure 4 , Figure 3 The side view of the second-floor buffer shelf 40 is removed for embodiment 1 of this utility model. Figure 4 Figure 3The enlarged schematic diagram at point A shows that, in this embodiment, laser sensors are provided on the top surfaces of both forks 21. During operation, the laser sensors detect and determine whether there is any obstruction in the picking direction of the forks 21, thereby detecting obstacles in the picking direction of the forks 21 in real time, preventing collision failures, and ensuring operational safety.

[0046] In this embodiment, a fixed seat 210 is fixedly provided on the top of the fork 21. A V-shaped fixing groove is provided on the top of the fixed seat 210. The V-shaped groove on the fixed seat 210 can firmly clamp the warp beam and prevent it from sliding during transportation. It is especially suitable for warp beams with large weight.

[0047] In this embodiment, the forks 21 inside the car 20 are telescopically moved via a telescopic chain 212. The chain drive structure is relatively traditional and simple. Routine maintenance only requires periodic lubrication and checking of chain tension, without complex adjustments. Although there are instantaneous speed fluctuations in the chain drive, in low-speed applications like the telescopic forks 21 (driven by a geared motor), these speed fluctuations have little impact on operation, and the overall operation is stable. The stability of the chain drive fully meets the requirements.

[0048] The car 20 has a fast door that is movably installed on one side to close the space of the car 20. The fast door can close the space of the car 20 during the movement of the car 20, thereby avoiding external interference. The structure and working principle of the fast door are existing technologies and will not be described in detail here.

[0049] The main frame 10 has detection mechanisms on both sides of the first floor area for detecting the positional error between the end face of the disc head at both ends of the shaft and the shaft end. The detection mechanism is also electrically connected to an alarm mechanism. The detection mechanism is used to detect the distance. When the detected distance does not meet the preset value, an alarm is triggered to notify manual handling. In this embodiment, the detection mechanism is a camera. The specific model can be an RGB-D camera, such as the Bluecore Technology S2 series camera. It can realize tray recognition, obstacle detection and stack detection through the depth data interface. It is suitable for mobile robot navigation and three-dimensional environmental perception in industrial scenarios. Other common cameras on the market can also be used, and it is not limited to this.

[0050] In this embodiment, the device is controlled by automatic control plus manual button confirmation, which ensures automation while ensuring operational safety through manual operation.

[0052] This embodiment also includes a buffer rack 40 for placing warp beams. The top of the buffer rack 40 is symmetrically inclined with at least four limiting plates 41, so that an obtuse angle is formed between two opposite limiting plates 41. The obtuse angle formed by the inclined limiting plates 41 can prevent the warp beams from rolling, optimize temporary storage space, reduce handling waiting time, and the obtuse angle can also adapt to a wider range of disc diameters, thereby enhancing applicability.

Then the forks 21 lift the pan head string 50 from the buffer rack 40. Afterwards, the forks 21 retract to move the pan head string 50 into the car 20. The fast door closes, the car 20 descends to the first floor area, the fast door opens again, and the forks 21 extend from the car 20 to move the pan head string to the AGV at the docking position 61.

Then, the car 20 rises to the second floor area and places the pan head string 50 on the buffer rack 40. The workers in the second floor area scan the barcode to confirm receipt and take away the pan head string 50.

[0059] In this embodiment, the head string 50 refers to an assembly formed by connecting multiple head strings 50 on a warp beam.

[0069] Chain-driven fork 21: The fork 21 is extended and retracted by a chain, which is easy to maintain (only requires lubrication and tension check), resistant to harsh environments such as dust and oil, suitable for low-speed scenarios, and has a lower cost than precision gear systems.

[0070] V-groove design: The V-groove on the top of the fork 21 securely clamps the shaft, preventing slippage and adapting to pan heads of different diameters.

[0071] High-speed door closure: The car's 20 high-speed door closes the space during operation, preventing external interference and shortening the cycle time.

[0072] Inclined limiting plate 41 buffer rack 40: Four symmetrical inclined limiting plates 41 form an obtuse angle (>90°) to prevent the warp shaft from rolling, adapt to various pan head sizes, and reduce adjustment time during temporary storage.

[0073] Multiple connection points configuration: 61 connection points and 40 buffer racks are set up in both the first and second floor areas to support flexible scheduling (such as AGV standby and workers scanning codes to pick up goods).
