Description

Technical Field

[0001] The invention relates to an automatic unwinding machine for nonwoven fabrics, which is suitable for automatically unwinding nonwoven fabrics after production is completed. Background Art

[0002] Nonwovens are generally produced in roll lengths based on order specifications, with most rolls weighing between 100-150 kg. Currently, manual unwinding is the most common method for unwinding nonwovens in the market. This method has two drawbacks: First, each roll weighs up to 100-150 kg, requiring two people to lift the finished nonwovens off the production line. Due to the weight of the fabric, poor coordination can easily lead to injury. Second, to ensure continuous production, workers must first cut the nonwovens, lift it off, and simultaneously install a new reel before starting production on the next roll. Nonwovens production speeds are typically high, at 50 m / min. Manual unwinding and reel installation are difficult to complete in a short time, resulting in significant waste. Summary of the Invention

[0003] The present invention addresses the above-mentioned shortcomings and provides an automatic nonwoven fabric unwinding machine that can be conveniently used with existing nonwoven fabric production lines. The automatic nonwoven fabric unwinding machine has a reasonable design and a compact structure. Automatic unwinding can reduce worker labor intensity and the occurrence of industrial accidents, while significantly improving production efficiency and reducing material waste.

[0004] An automatic unwinding machine for nonwoven fabrics is realized by adopting the following technical solutions:

[0005] The nonwoven fabric automatic unwinding machine comprises a shuttle mechanism, a winding device, a take-up device, a docking device, a cutter mechanism, an automatic unwinding electronic control system, and a rewinding device. The winding devices are located at both ends of the shuttle vehicle base, the take-up device is located between the winding devices, the docking device is located at the center of one side of the shuttle vehicle base, and the cutter mechanism is located at the same end as the docking device. The rewinding device is located between the nonwoven fabric production equipment and the shuttle mechanism.

[0006] After the nonwoven roll is completed, the automatic unwinding electronic control system controls the heating of the electric soldering wire. Simultaneously, the shuttle motor activates, driving the shuttle mechanism along the shuttle rails. When the position sensor on the docking mechanism detects alignment between the shuttle mechanism and the rewinding mechanism, the docking cylinder pushes the docking shaft forward, locking it with the docking port on the rewinding mechanism. The rewinding mechanism cylinder retracts, driving the meniscus mounted on the stop shaft, causing the stop shaft to move upward, forming a stopper. Simultaneously, the rewinding mechanism's electronic control unit controls the rewinding cylinder to retract, adjusting the rewinding boom from its previous 30° angle to a negative angle. Gravity forces the rewinding shaft to roll onto the rewinding mechanism. The rewinding motor activates, rotating the rewinding drive shaft, which in turn drives the nonwoven roll further within the rewinding mechanism, ensuring that the linear speed of the nonwoven roll matches that of the rewinding drive roller. The cutter mechanism's lifting cylinder then moves upward, driving the hot electric soldering wire into contact with the nonwoven fabric, severing the nonwoven fabric and completing the fabric cutting process. When the nonwoven roll lands on the take-up unit, the unwinding mechanism begins operating. The unwinding cylinder extends, rotating the movable arm and placing the replacement reel from the unwinding mechanism onto the rewinding boom. The rewinding cylinder then returns the rewinding boom to its working angle. Gravity forces the replacement reel into contact with the active rewinding roller, beginning the rewinding of the next roll. The docking cylinder disengages the reel from the docking port on the rewinding mechanism, and the shuttle motor drives the shuttle mechanism back to the next process position, completing the automatic unwinding process.

[0007] The shuttle device consists of a shuttle rail, two sets of guide rollers, a shuttle base, two sets of shuttle wheels, a shuttle belt, and a shuttle motor. The shuttle rail is mounted on the ground, while the guide rollers are mounted at the bottom of each end of the shuttle base, contacting the shuttle rail to form a sliding rail system. The two sets of shuttle wheels are spaced at the ends of the shuttle base, and the shuttle motor is mounted above one set of shuttle wheels. During operation, the shuttle motor drives the shuttle wheels via the belt, causing the shuttle device to move along the shuttle rail.

[0008] The winding device consists of two winding cylinders, two winding mounting plates, two movable arms, a movable arm connecting rod, a photoelectric sensor, and a replacement winding shaft. The winding mounting plates are mounted on either side of the shuttle base, and the two movable arms are mounted on the outer sides of the winding mounting plates. The two movable arms are connected by a movable arm connecting rod. A photoelectric sensor is installed at the center of the movable arm connecting rod. The top of the movable arm has a smooth groove structure, into which the replacement winding shaft can roll when the movable arm is at a negative angle. During operation, the winding cylinder moves, driving the movable arm to rotate, feeding the replacement winding shaft onto the winding cantilever on the winding device, completing the winding action. The photoelectric sensor detects whether the replacement winding shaft is on the winding device. During the unwinding operation, if the replacement winding shaft is not on the winding device, the system automatically alarms. After winding is completed, the photoelectric sensor sends a signal, and the automatic unwinding electronic control system controls the retraction of the movable arm.

[0009] The unwinding device consists of a unwinding stop shaft, two stop shaft mounting menisci, a unwinding active shaft, a unwinding passive shaft, two sets of unwinding cylinders, a unwinding active shaft motor, and a belt. The two stop shaft mounting menisci are mounted on the inner sides of the two upper roll mounting plates. One end of the stop shaft mounting menisci is connected to the unwinding cylinder, and the other end connects the two stop shaft mounting menisci through the unwinding stop shaft. The unwinding active shaft is mounted below the center position of the stop shaft menisci, and one end of the unwinding active shaft is mounted with a unwinding active shaft motor. The unwinding passive shaft is mounted between the two upper roll mounting plates. The unwinding stop shaft and the unwinding passive shaft are both rotatable shafts with smooth surfaces, while the unwinding active shaft is a rubber roller with a rough surface. During operation, the unwinding device cylinder retracts, driving the stop shaft mounting menisci to move, and the stop shaft moves upward to form a stop plate. At the same time, the take-up motor starts, driving the take-up active shaft to rotate, ensuring that when the non-woven fabric roll reaches the take-up device, the non-woven fabric winding speed remains consistent with the winding roller speed, completing the take-up action.

[0010] The docking device consists of three position sensors, a docking cylinder, a set of docking shafts, and slide rails. The three position sensors are mounted on either side and in the center of the shuttle base. When the position sensors on the docking device detect that the shuttle is aligned with the winding device, the docking cylinder pushes the docking shaft forward, locking it with the docking port on the winding device, completing the docking operation.

[0011] The cutter mechanism consists of an electric soldering wire, a soldering wire mounting base, and two lifting cylinders. The cutter mechanism is mounted on the shuttle base, above the docking device at the same end. When the rewinding device completes the rewinding operation, the cutter mechanism's lifting cylinders move upward, driving the high-temperature electric soldering wire into contact with the nonwoven fabric, severing the nonwoven fabric and completing the fabric cutting operation.

[0012] The automatic unwinding electric control system synchronously controls the actions of the reciprocating device, the winding device, the winding device, the docking device, the cutter mechanism and the winding device according to the nonwoven fabric meter number signal detected by the winding electric control unit of the winding device.

[0013] The winding device consists of a winding electronic control unit, two winding cylinders, two winding cantilevers, a replacement winding shaft, a winding active roller, a winding motor and a docking port. The winding cantilevers are installed on both sides and driven by the winding cylinders. The angle of the winding cantilevers can be adjusted. During normal production, the angle of the winding cantilever is 30°. The winding shaft placed between the two winding cantilevers contacts the winding active roller under the action of gravity to achieve winding. When production is completed and it is necessary to unwind, the winding electronic control unit controls the winding cylinder to retract, and the angle of the winding cantilever becomes a negative angle. Under the action of gravity, the winding shaft slides from the winding cantilever into the winding device. The angle of the winding cantilever can be adjusted within -15° to 30°.

[0014] An automatic unwinding method for a nonwoven fabric automatic unwinding machine:

[0015] When a nonwoven fabric automatic unwinding machine is in operation, when the winding electronic control unit in the winding device detects that the nonwoven fabric has been produced, the automatic unwinding electronic control system controls the electric soldering wire to begin heating, and the shuttle motor starts operating, driving the shuttle device along the shuttle guide rail. When the position sensor on the docking device senses that the shuttle device is aligned with the winding device, the docking cylinder pushes the docking shaft forward, locking it with the docking port on the winding device. The take-up device cylinder retracts, driving the meniscus mounted on the stop shaft to move upward, forming a stopper. Simultaneously, the winding electronic control unit controls the retraction of the winding cylinder, adjusting the winding cantilever from the previous 30° angle to a negative angle, and the winding shaft rolls onto the take-up device under the action of gravity. The take-up drive shaft motor starts, driving the take-up drive shaft to rotate, driving the nonwoven fabric roll to continue moving within the take-up device, ensuring that the linear speed of the nonwoven fabric roll is consistent with the linear speed of the winding drive roller. The cutter mechanism's lifting cylinder moves upward, driving the high-temperature electric soldering wire into contact with the nonwoven fabric, severing the nonwoven and completing the fabric cutting process. When the nonwoven roll rolls onto the take-up device, the unwinding mechanism begins operating. The unwinding cylinder extends, rotating the movable arm and placing the replacement reel from the unwinding mechanism onto the rewinding boom. The rewinding cylinder drives the rewinding boom back to its operating angle, and gravity forces the reel into contact with the active rewinding roller, beginning the process of rewinding the next roll of fabric. The docking cylinder disengages the docking shaft from the docking port on the rewinding mechanism, and the shuttle motor drives the reciprocating mechanism back to the next process position, completing the automatic unwinding process.

[0016] This nonwoven fabric automatic unwinding machine features a rational design and compact structure. It is equipped with a reciprocating mechanism, a winding device, a reeling device, a reeling device, a docking device, a cutting mechanism, an automatic unwinding electronic control system, and a rewinding device. It can be easily integrated with existing nonwoven fabric production lines. The device has a simple structure, reduces equipment maintenance workload, and achieves automatic unwinding, alleviating worker labor intensity. Workers rarely need to enter the operating area of the equipment, and manual loading and unloading of the reel is no longer necessary, effectively avoiding the possibility of mechanical injuries and reducing the occurrence of industrial accidents.

[0017] An automatic nonwoven fabric unwinder can save 25% of labor costs (based on four production lines per workshop, replacing the unwinding device with the automatic nonwoven fabric unwinder reduces the number of production staff required per shift from 16 to 12). The automatic nonwoven fabric unwinder automatically records production data and automatically unwinds when the set production volume is reached. This reduces material waste during manual unwinding and eliminates the irregularities of hand-cut fabric, significantly improving production efficiency and material utilization.

The rewinding device 7 is located between the nonwoven fabric production equipment and the shuttle device 1.

[0032] The shuttle device 1 consists of a shuttle rail 11, two sets of guide rollers 12, a shuttle base 12, two sets of shuttle wheels 14, a shuttle belt 15, and a shuttle motor 16. The shuttle rail 11 is mounted on the ground. The guide rollers 12 are mounted at the bottom of each end of the shuttle base 12, contacting the shuttle rail 11 to form a slide rail system. The two sets of shuttle wheels 14 are mounted at intervals at the bottom of the shuttle base 12, and the shuttle motor 16 is mounted above one set of shuttle wheels 14. During operation, the shuttle motor 16 drives the shuttle wheels 14 to rotate via the belt 15, causing the shuttle device 1 to move along the shuttle rail 11.

The two movable arms 23 are mounted on either side of the winding mounting plates 22 and connected by the movable arm connecting rod 24. A photoelectric sensor 25 is mounted at the center of the movable arm connecting rod 24. The tops of the movable arms 23 have smooth grooves, allowing the replacement reel 26 to roll down within the grooves when the movable arms 23 are at a negative angle. During operation, the winding cylinders 21 rotate, driving the movable arms 23 to feed the replacement reel 26 onto the reeling cantilever 74 on the reeling device 7, completing the winding operation. The photoelectric sensor 25 detects whether the replacement reel 26 is on the winding device 2.

One end of the block shaft mounting menisci 32 is connected to the reeling cylinder 35, and the other end connects the two block shaft mounting menisci 32 through the reeling block shaft 31. The reeling active shaft 33 is mounted below the center position of the block shaft mounting menisci 32. One end of the reeling active shaft 33 is mounted with a reeling active shaft motor 36. The reeling passive shaft 34 is mounted between the two upper reel mounting plates 22. The reeling block shaft 31 and the reeling passive shaft 34 are both rotatable shafts with smooth surfaces, while the reeling active shaft 33 is a rubber roller with a rough surface. During operation, the take-up device cylinder 35 retracts, driving the meniscus 32 mounted on the stop shaft to move, causing the stop shaft 31 to move upward to form a stop plate. Simultaneously, the take-up motor 36 starts, driving the take-up drive shaft 33 to rotate, ensuring that when the nonwoven fabric roll reaches the take-up device 3, the linear speed of the nonwoven fabric winding remains consistent with the linear speed of the winding roller 76, completing the take-up operation.

[0035] The docking device 4 consists of three position sensors 44, a docking cylinder 41, a set of docking shafts 42, and slide rails 43. The three position sensors 44 are mounted on both sides and in the center of the shuttle base 13. When the position sensors 44 on the docking device 4 sense that the shuttle 1 is aligned with the winding device 7, the docking cylinder 41 pushes the docking shaft 42 forward, locking it with the docking port 73 on the winding device 7, completing the docking operation.

[0036] The cutter mechanism 5 consists of an electric soldering wire 51, an electric soldering wire mounting base 52, and two lifting cylinders 53. The cutter mechanism 5 is mounted on the shuttle base 13, above the same end as the docking device 4. When the reel splicer 3 completes the reeling operation, the lifting cylinders 53 of the cutter mechanism 5 move upward, driving the high-temperature electric soldering wire 51 into contact with the nonwoven fabric, severing the nonwoven fabric and completing the fabric cutting operation.

[0037] The automatic unwinding electric control system 6 synchronously controls the actions of the reciprocating device 1, the winding device 2, the winding device 3, the docking device 4, the cutter mechanism 5, and the winding device 7 according to the non-woven fabric meter number signal detected by the winding electric control unit 71 on the winding device 7.

[0038] The supporting parts of the automatic unwinding electric control system 6 of nonwoven fabrics include an electrical control box and an electrical control switch, AC contactor, relay, PLC programmable controller, control circuit board, motor controller, air source processor, solenoid valve, etc. installed in the electrical control box.

The winding arms 74 are mounted on both sides and driven by the winding cylinders 72, allowing the angle of the winding arms 74 to be adjusted. During normal production, the angle of the winding arms 74 is 30°. The nonwoven fabric winding shaft 75, placed between the winding arms 74, contacts the winding active roller 76 under the action of gravity, achieving winding. When production is completed and unwinding is required, the winding electronic control unit 71 controls the winding cylinders 72 to retract, causing the angle of the winding arms 74 to become negative, and the nonwoven fabric winding shaft 75, under the action of gravity, slides from the winding arms 74 into the winding device 7. The angle of the winding arms 74 can be adjusted within a range of -15° to 30°.

[0040] The winding electric control unit 71 is provided with a nonwoven fabric meter counter, a winding cantilever cylinder controller, a winding motor controller, and a PLC programmable controller.

[0041] An automatic unwinding method for a nonwoven fabric automatic unwinding machine:

[0042] When a nonwoven fabric automatic unwinding machine is in operation, when the rewinding electronic control unit 71 in the rewinding device 7 detects that the nonwoven fabric has been produced, the automatic unwinding electronic control system controls the electric soldering wire 51 to begin heating, and the shuttle motor 16 starts operating, driving the shuttle device 1 along the shuttle guide rail 11. When the position sensor 44 on the docking device 4 senses that the shuttle device 1 is aligned with the rewinding device 7, the docking cylinder 41 pushes the docking shaft 42 forward, locking it with the docking port 73 on the rewinding device 7. The rewinding cylinder 35 of the rewinding device 3 retracts, driving the meniscus 32 mounted on the blocking shaft to move upward, forming a baffle. At the same time, the rewinding electronic control unit 71 of the rewinding device 7 controls the rewinding cylinder 72 to retract, adjusting the rewinding cantilever 74 from the previous 30° angle to a negative angle, and the rewinding shaft 75 rolls onto the rewinding device 3 under the action of gravity. The take-up drive shaft motor 36 starts, rotating the take-up drive shaft 33 and continuing the movement of the nonwoven fabric roll within the take-up device 3, ensuring that the linear speed of the nonwoven fabric roll is consistent with the linear speed of the take-up drive roller 76. The lifting cylinder 53 of the cutter mechanism 5 moves upward, driving the high-temperature electric soldering wire 51 to contact the nonwoven fabric, severing the nonwoven fabric and completing the fabric cutting operation. When the nonwoven fabric roll rolls onto the take-up device 3, the reeling device 2 begins operation. The reeling cylinder 21 extends, rotating the movable arm 23 and placing the replacement reel 26 on the reeling device 2 onto the reeling boom 74. The reeling cylinder 72 drives the reeling boom 74 back to its operating angle. Under the influence of gravity, the nonwoven fabric reel 75 contacts the reeling boom 76, and the reeling of the next roll of fabric begins. The docking cylinder 41 drives the docking shaft 42 to disengage from the docking port 73 on the winding device 7, and the shuttle motor 16 drives the shuttle device 1 to return to the next process position, completing the automatic unwinding process.
