Description

Technical Field

[0001] This invention relates to the field of cold stacking treatment of printed and dyed fabric rolls, and in particular to a fully automated stacking system and method. Background Technology

[0002] Before dyeing, the fabric needs to undergo cold stacking and rolling. Due to the presence of the rolling frame at the fabric exit end of the cold stacking and rolling machine, the fabric rolls cannot be directly hoisted by an overhead crane. Currently, the cold stacking and rolling process involves workers pushing an A-frame trolley equipped with an empty roller to the bottom of the rolling frame of the rolling machine for rolling. After rolling, workers then push the A-frame trolley containing the fabric rolls to the cold stacking area for cold stacking. This method has the following drawbacks:

[0003] 1) The entire process requires manual transfer and pushing by workers, which is labor-intensive and inefficient.

[0004] 2) The cooling time is monitored by workers, which is prone to errors, resulting in excessive or insufficient cooling time, making it difficult to guarantee the quality of the cooling and thus affecting the quality of subsequent processing.

[0005] 3) During the transfer of fabric, the cold-stacked fabric rolls are relatively damp, and water droplets will fall on the workshop floor during the movement and cold stacking process, making the workshop floor more slippery. Workers are prone to slipping and falling when pushing the trolley, which poses a safety hazard.

[0006] Therefore, existing technologies suffer from problems such as high labor intensity for workers, low efficiency, certain safety hazards, and difficulty in guaranteeing the quality of cold reactors. Summary of the Invention

[0007] The purpose of this invention is to provide a fully automated stacking system and method. This invention can not only effectively reduce the labor intensity of workers and improve stacking and transfer efficiency, but also eliminate safety hazards while ensuring the quality of cold stacking.

[0008] The technical solution of the present invention is as follows: a fully automatic stacking system, including a fabric roll stacking area, one end of which is provided with a fabric roll inbound translation mechanism corresponding to the discharge side of the cold stacking and rolling machine, and the other end of which is provided with a fabric roll outbound translation mechanism; it also includes a crane mechanism located above the fabric roll stacking area.

[0009] In the aforementioned fully automatic stacking system, the fabric roll stacking area includes one or more parallel fabric roll stacking racks. Each fabric roll stacking rack has a set of side-by-side fabric roll placement rotating seats on both the front and back sides. One side of the fabric roll placement rotating seat is provided with a fabric roll rotation drive assembly. The bottom of the fabric roll stacking rack is provided with a water receiving trough.

[0010] In the aforementioned fully automatic stacking system, the fabric roll entering the warehouse and moving mechanism includes a movable track frame located on the discharge side of the cold stacking and rolling machine. An A-frame trolley is provided on the movable track frame, and a pulling hydraulic cylinder is provided at the tail end of the movable track frame. The output end of the pulling hydraulic cylinder is connected to the A-frame trolley. The tail end of the movable track frame is also provided with an empty roller placement area.

[0011] In the aforementioned fully automated stacking system, the fabric roll outward translation mechanism includes a ground rail located at the fabric roll outward end of the stacking area, an A-frame outward trolley mounted on the ground rail, and an outward hydraulic cylinder mounted on the ground rail, the output end of which is connected to the A-frame outward trolley.

[0012] In the aforementioned fully automated stacking system, the overhead crane mechanism includes a lateral trolley assembly that moves left and right, a longitudinal trolley assembly that moves back and forth on the lateral trolley assembly, a two-section rigid telescopic arm assembly on the longitudinal trolley assembly, and a fabric roll clamp below the two-section rigid telescopic arm assembly; the fabric roll clamp includes a clamp base plate, and supports are provided at both ends below the clamp base plate, with a roller bidirectional clamping assembly on the supports.

[0013] In the aforementioned fully automated stacking system, the two-section rigid telescopic arm assembly includes a fixed arm fixed in the middle of the longitudinal trolley assembly, a lifting movable arm inside the fixed arm, and a cloth roll clamp fixed to the bottom of the lifting movable arm; it also includes a lifting drive module located in cooperation with the lifting movable arm.

[0014] In the aforementioned fully automatic stacking system, the roller bidirectional clamping assembly includes a double-headed hydraulic cylinder fixed to the outside of the support and arranged vertically. The upper and lower output ends of the double-headed hydraulic cylinder are provided with arc-shaped clamps, and the inner wall of the arc-shaped clamps is embedded with magnets.

[0015] A method for a fully automated stacking system, the specific stacking process is as follows:

[0016] S1. After the cold stack coiling machine has coiled the fabric, the operator scans the process flow card using the on-site human-machine interface, and presses the "inventory" button after confirming that the information found is correct and the process flow is correct.

[0017] S2. The fabric roll is moved from the cold stacker to the storage position by the fabric roll warehousing translation mechanism;

[0018] S3. The overhead crane lifts the fabric roll from the A-frame trolley and then places the fabric roll into the inbound buffer area at the inbound end of the fabric roll stacking area.

[0019] S4. The overhead crane mechanism grabs an empty roller from the empty roller placement area and places it on the A-frame trolley. Then, the fabric roll-in silo translation mechanism moves the A-frame trolley to the fabric outlet position of the cold stacker.

[0020] S5. The overhead crane moves the fabric roll located in the warehouse buffer area to the designated stacking position and starts counting down according to the stacking time set by the process.

[0021] S6. When the stacking time countdown reaches 0, the system dashboard will flash yellow and the indicator light will flash yellow to indicate this.

[0022] S7. After the operator scans the process flow card on the outbound human-machine interface, the system will prompt the corresponding fabric roll stacking time. The operator can press the outbound button to move the corresponding fabric roll to the outbound buffer area and complete the outbound process through the fabric roll outbound translation mechanism.

[0023] Compared with existing technologies, this invention comprises a fabric roll stacking area, a fabric roll inbound and outbound horizontal transfer mechanism, and a crane mechanism located above the fabric roll stacking area. This achieves fully automated operation of the fabric roll process—from the output end of the cold-stacking fabric roll machine to the inbound operation in the stacking area, the stacking of fabric rolls in the stacking area, and the outbound operation of fabric rolls. This replaces the traditional manual pushing, transferring, and stacking method, significantly reducing worker workload, improving cold-stacking and transfer efficiency, eliminating safety hazards, and preventing worker slips. Furthermore, this application automatically monitors the stacking time through the system, effectively ensuring the quality of cold-stacking. In summary, this invention not only effectively reduces worker workload and improves stacking and transfer efficiency but also eliminates safety hazards and ensures the quality of cold-stacking.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0036] Example. A fully automated stacking system, configured as follows: Figure 1-10 As shown, it includes a fabric roll stacking area 1, one end of which is provided with a fabric roll inbound translation mechanism 3 corresponding to the discharge side of the cold stacking and rolling machine 2, and the other end of which is provided with a fabric roll outbound translation mechanism 4; it also includes a crane mechanism 5 located above the fabric roll stacking area 1.

An A-frame trolley 302 is provided on the movable track frame 301. A pulling hydraulic cylinder 303 is provided at the tail end of the movable track frame 301. The output end of the pulling hydraulic cylinder 303 is connected to the A-frame trolley 302. The tail end of the movable track frame 301 is also provided with an empty roller placement area 304.

[0039] The fabric roll outward translation mechanism 4 includes a ground rail 401 located at the fabric roll stacking area 1 at the fabric outward end. An A-frame outward trolley 402 is provided on the ground rail 401. An outward hydraulic cylinder 403 is also provided on the ground rail 401. The output end of the outward hydraulic cylinder 403 is connected to the A-frame outward trolley 402.

[0040] The overhead crane mechanism 5 includes a lateral trolley assembly 501 that moves left and right, a longitudinal trolley assembly 502 that moves back and forth on the lateral trolley assembly 501, a two-section rigid telescopic arm assembly 503 on the longitudinal trolley assembly 502, and a fabric roll clamp 504 below the two-section rigid telescopic arm assembly 503; the fabric roll clamp 504 includes a clamp base plate 541, and supports 542 are provided at both ends below the clamp base plate 541, and a roller bidirectional clamping assembly 543 is provided on the supports 542.

[0041] The two-section rigid telescopic boom assembly 503 includes a fixed arm 531 fixed in the middle of the longitudinal trolley assembly 502, a lifting movable arm 532 provided inside the fixed arm 531, and a cloth roll clamp 504 fixed to the bottom of the lifting movable arm 532; it also includes a lifting drive module located in cooperation with the lifting movable arm 532.

[0042] The roller bidirectional clamping assembly 543 includes a double-headed hydraulic cylinder 544 fixed to the outside of the bracket 542 and arranged vertically. The upper and lower output ends of the double-headed hydraulic cylinder 544 are provided with arc-shaped clamps 545, and the inner wall of the arc-shaped clamps 545 is embedded with magnets.

[0043] A method for a fully automated stacking system, the specific stacking process is as follows:

[0044] S1. After the cold stack coiling machine has coiled the fabric, the operator scans the process flow card using the on-site human-machine interface, and presses the "inventory" button after confirming that the information found is correct and the process flow is correct.

[0045] S2. The fabric roll is moved from the cold stacker to the storage position by the fabric roll warehousing translation mechanism;

[0046] S3. The overhead crane mechanism lifts the fabric roll from the A-frame trolley and then places the fabric roll into the inbound buffer area at the inbound end of the fabric roll stacking area.

[0047] S4. The overhead crane mechanism grabs an empty roller from the empty roller placement area and places it on the A-frame trolley. Then, the fabric roll-in silo translation mechanism moves the A-frame trolley to the fabric outlet position of the cold stacker.

[0048] S5. The overhead crane moves the fabric roll located in the warehouse buffer area to the designated stacking position and starts counting down according to the stacking time set by the process.

[0049] S6. When the stacking time countdown reaches 0, the system dashboard will flash yellow and the indicator light will flash yellow to indicate this.

[0050] S7. After the operator scans the process flow card on the outbound human-machine interface, the system will prompt the corresponding fabric roll stacking time. The operator can press the outbound button to move the corresponding fabric roll to the outbound buffer area and complete the outbound process through the fabric roll outbound translation mechanism.

[0051] The inbound end of the fabric roll stacking area is equipped with a fabric roll inbound buffer area, and the outbound end of the fabric roll stacking area is equipped with a fabric roll outbound buffer area.

[0052] The A-frame trolley includes an A-frame body, with moving wheels at the bottom of the A-frame body that cooperate with the moving track frame. The upper surface of the A-frame body is provided with a rotating adjustment seat, and roller placement frames are provided at the front and rear ends of the rotating adjustment seat.

[0053] The upper surface of the A-frame body is provided with a bearing seat in the middle. The bearing seat contains a rotating shaft connected to the bottom of the rotating adjustment seat. The rotating shaft is provided with a driven gear, and a drive gear meshes with the side of the driven gear. The drive gear is connected to a drive motor.

[0054] This application provides a rotary adjustment seat and a roller placement frame on the upper part of the A-frame trolley. The rotary adjustment seat rotates under the drive of a driven gear, a drive gear, a rotating shaft, and a drive motor, allowing the rotary adjustment frame to rotate and adjust freely to adapt to different fabric roll output directions.

[0055] The mobile track frame is fixed to the ground.

[0056] The empty roller placement area is located above the pulling hydraulic cylinder.

[0057] The roller placement rack is equipped with a roller rotation drive module, which is used to drive the roller to rotate during rolling.

[0058] In the initial state, the A-frame trolley equipped with the empty roller is located below the winding frame of the cold stack winding machine. After the fabric end is fixed on the empty roller, the winding and fabric output operation begins.

[0059] When the workshop space is limited and the discharge side of the cold reactor coiler is inconsistent with the hoisting path of the gantry crane assembly, the position and angle of the screw adjustment seat can be adjusted after the A-frame trolley is pulled away from the coiling frame of the cold reactor coiler to make it consistent with the hoisting path of the gantry crane assembly. This facilitates hoisting and installation of the cold reactor coiler, reduces the requirements for the installation location of the cold reactor coiler, and improves installation flexibility.

[0060] The adjustment process of the rotary adjustment seat on the A-frame trolley: The drive motor works, which drives the drive gear to rotate. The rotation of the drive gear will drive the driven gear meshing with it to rotate. The rotation of the driven gear will drive the rotating shaft to rotate, which in turn will drive the rotary adjustment seat to rotate.

[0061] The bracket is equipped with an infrared detection sensor and a pressure sensor corresponding to the position of the dual-head hydraulic cylinder.

[0062] Both the longitudinal and lateral trolley components utilize Leuze's laser barcode scanning technology for positioning, enabling intelligent vehicle tracking and location. This sensor is safe and visible, features a square aluminum housing with IP65 protection, a measurement distance of up to 10,000 meters, a positioning accuracy of ±1mm, and multiple built-in communication interfaces.

[0063] The traveling vehicle carries the reading head, which uses laser lines to cut the barcode strip. Through algorithms, the center value of the reading head, or absolute position value, is obtained; the highest accuracy can reach ±0.15mm; it can also output speed values, with a maximum speed of 10 meters per second.

[0064] By using a two-section rigid telescopic arm assembly to drive the traditional wire rope, swaying during fabric roll transfer is effectively prevented, ensuring the stability of the fabric roll during transport. Simultaneously, by incorporating a two-way roller clamping assembly on the fabric roll clamp, the rollers of the fabric roll are effectively clamped, further enhancing the clamping strength and stability of the fabric roll during transfer, preventing swaying.

[0065] The lifting drive module can adopt a hydraulic lifting mode. For example, a hydraulic cylinder is installed at the top of the fixed arm, and a lifting rod is provided at the output end of the hydraulic cylinder. The lifting rod is connected to the top of the lifting movable arm, and rollers that cooperate with the fixed arm are also provided on both sides of the lifting movable arm. Alternatively, a traction lifting method similar to that of an elevator can be used, with a traction machine and traction sheave installed on the moving trolley, and rope sheaves installed at the top of the fixed arm and the movable arm. The rope sheaves pass around each rope sheave and traction sheave in sequence to drive the vertical lifting.

[0066] The lateral traveling mechanism uses one frequency converter to control two motors in open-loop control. Speed ​​is controlled from 10% to 100%, achieving a 1:10 speed ratio. The braking resistor's duty cycle and power value, braking frequency, and braking torque are adjustable. Deceleration and braking control: Braking employs a combination of mechanical and electric braking. The mechanical braking uses a normally closed brake mounted on the high-speed shaft. Stopping methods: During normal stopping, the mechanism first uses electric braking; when the running speed drops to the set low speed, the brake engages. Fault stopping: When the speed control device's power supply is cut off, the brake immediately engages, and a fault alarm signal is issued. Electrical protection: The frequency converter itself is equipped with monitoring and protection against overcurrent, overload, overvoltage, undervoltage, phase loss, momentary power outage, output grounding, and field communication faults. When any of these faults occur, the frequency converter will stop working, and the mechanism will stop according to the fault-stopping procedure.

[0067] The longitudinal traveling mechanism uses one frequency converter to control one motor in open-loop control. Speed ​​is controlled from 10% to 100%, achieving a 1:10 speed regulation. The braking resistor's duty cycle and power value, braking frequency, and braking torque are selected. Deceleration and braking control: Braking employs a combination of mechanical and electric braking. Mechanical braking uses a normally closed brake mounted on the high-speed shaft. Stopping methods: During normal stopping, the mechanism first uses electric braking; when the running speed drops to the set low speed, the brake engages. Fault stopping: When the speed control device's power supply is cut off, the brake immediately engages, and a fault alarm signal is issued. Limit switches are installed at each door of the bridge crane. When the intelligent traveling door opens, the traveling mechanism stops according to the fault stopping sequence. Electrical protection: The frequency converter itself is equipped with monitoring and protection against overcurrent, overload, overvoltage, undervoltage, phase loss, instantaneous power outage, output grounding, and field communication faults. When any of the above faults occur, the frequency converter will stop working, and the mechanism will stop according to the fault stopping procedure.

[0068] The working process of the two-section telescopic boom assembly: The lifting drive module drives the lifting boom to move up and down along the fixed boom, thereby realizing the lifting boom's up and down movement.

[0069] The working process of the fabric roll clamp: When clamping is required, the output end of the double-headed hydraulic cylinder retracts, causing the upper and lower arc-shaped clamps to clamp the upper and lower sides of the roller. At the same time, the magnet will further attract the roller.

[0070] The working process of the overhead crane assembly is as follows: The lateral trolley assembly moves the longitudinal trolley assembly and the fabric roll clamp left and right to the corresponding lateral positions. Then, the longitudinal trolley assembly moves the fabric roll clamp forward and backward to the corresponding longitudinal position, thus completing the lateral and forward / backward position adjustment of the fabric roll clamp. Next, the two-section telescopic arm assembly drives the fabric roll clamp to descend. After the infrared detection sensor of the fabric roll clamp detects the fabric roll's rollers, the controller stops the descent of the two-section telescopic arm assembly. Then, the lateral trolley assembly moves the fabric roll clamp towards the rollers until the fabric roll rollers contact the support (monitored by a pressure sensor). The roller bidirectional clamping assembly then starts working, driving the arc-shaped clamps to clamp the rollers from both above and below, completing the clamping of the fabric roll rollers. Then, the lifting drive module drives the lifting arm to rise. The lateral and longitudinal trolley assemblies work together to hoist the fabric roll to the pre-set position.

[0071] The working process of this invention:

[0072] Automated inventory process

[0073] After the cold reactor coiling is completed, the operator scans the process flow card on the warehousing computer and compares it with the data displayed on the warehousing computer. After confirming that there are no errors, the operator selects an empty storage location. The system will pop up a confirmation window again. After the operator confirms that it is correct, the operator presses the warehousing button to start the warehousing process.

[0079] Steps 4 and 5 are performed simultaneously.

[0080] Automated outbound process

[0081] The operator scans the process flow card on the outbound computer and compares it with the data displayed on the computer. After confirming that there are no errors, the operator presses the outbound button. The system will then pop up a confirmation window. After the operator confirms that everything is correct, the operator presses the outbound button again to start the outbound process.
