Description

Technical Field

[0001] The invention belongs to the field of film processing equipment, and in particular relates to a slitting machine and a use method thereof. Background Art

[0002] At present, there are many types of slitting machines, and their prices vary greatly due to their different sizes, materials, and automation levels. In the process of placing wide-width coils, slitting machines are currently basically operated manually. The labor intensity and cumbersomeness of manual operation vary according to the design, market demand, and manufacturing costs of different manufacturers.

[0003] Through investigation and research on the slitting machines in the prior art, it can be roughly summarized into the following two ways of placing wide-width coils: (1) The air shaft fixing seat has a single degree of freedom, and the air shaft has two degrees of freedom. The air shaft fixing seat slides on the guide rail, and the two air shaft fixing seats move relatively outward along the air shaft to reserve enough space for unwinding. After the two air shaft fixing seats move outward, a trolley is used to push the wide-width coil to the installation position. The platform of the trolley supporting the wide-width coil can be raised and lowered to adjust the position so that the axis of the wide-width coil can be aligned with the axis of the air shaft. After the wide-width coil is aligned with the air shaft, the air shaft is restored to fix the wide-width coil. Because the air shaft can move with the air shaft fixing seat, and the air shaft itself can rotate, the air shaft has two degrees of freedom. (2) The air shaft fixing seat has two degrees of freedom, and the air shaft has three degrees of freedom. As described in (1), the air shaft fixing seat can be moved outward to reserve a position for the installation of the wide-width coil. This unwinding method does not use the lifting platform of the trolley to support the wide-width coil, but directly places the wide-width coil on the ground or on an ordinary trolley, and then the air shaft fixing seat is rotated along the Y-axis to lower the height of the air shaft. After the axis of the wide-width coil is aligned with the axis of the air shaft, the air shaft fixing seat clamps the coil through translation and rotation and returns to its original position.

[0004] Both the above-mentioned method (1) and method (2) are manually operated, so there are inevitable shortcomings in production, which greatly affect production efficiency. In method (1), the coil is placed at the predetermined position by a trolley. When the air shaft passes through the wide coil core, the worker needs to manually fine-tune the position of the wide coil so that the air shaft can smoothly pass through the core. In addition, the lifting platform of the trolley needs to be calibrated frequently, otherwise the height of the core and the air shaft will be inconsistent, and the wide coil cannot be installed; method (2) does not use a trolley with a lifting platform, which can avoid the step of adjusting the lifting platform, but fine-tuning during the installation process is still unavoidable, and a certain amount of manual operation is still required. The efficiency of the worker's operation depends on the proficiency of the work, but no matter how proficient the worker is in the operation, manual operation still restricts the production efficiency of the slitting machine.

[0005] Based on the above description, it can be seen that the current slitting machine has at least the following deficiencies in placing wide-width coils: low automation, high labor intensity for workers, long loading and unloading time, and low overall production efficiency.

[0006] In the process of unloading the slitting machine, it is currently mostly achieved through manual operation. Some low-cost equipment has a simple overall structure. When unloading, it is often necessary to remove the connection between the winding slip shaft and the winding servo motor or other components, and then manually unload and move the rolls of materials. Some more advanced slitting machines have higher production costs and have certain auxiliary configurations when unloading, which can reduce the labor intensity of workers to a certain extent, but there are still problems such as long unloading time and low unloading efficiency.

[0007] After unloading, it is necessary to put multiple paper rolls for winding on the differential axis. At present, the paper rolls are basically installed and positioned manually. Some advanced slitting machine manufacturers have automatic loading and unloading systems, but they still install the paper rolls manually with laser-assisted positioning. Slitting machine manufacturers with slightly backward technology rely on manual installation and make the paper rolls longer, so that they can be inserted faster and do not need the positioning of the laser system.

[0008] Based on the above analysis, the current slitting machine has the following deficiencies in the process of winding and unloading and installing paper tubes: 1. In the process of winding and unloading, the degree of automation is low, and there is a lack of corresponding electro-hydraulic auxiliary systems. The labor intensity of workers in unloading is high and the unloading time is long, which affects the overall production efficiency. 2. In the process of installing paper tubes, manual operation is required, the loading efficiency is low, and the positioning accuracy is relatively low. The low accuracy leads to different sizes of each roll after winding. The wound rolls do not fall in the same position, and may be on the left or right. In addition, the length of the paper tube is long. In the entire production process, the length of each paper tube is redundant, and the manufacturing cost of the paper tube will increase. Summary of the invention

[0009] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology, and to provide a slitting machine device with less manual operation, high production efficiency and high positioning accuracy, and a method for using the above slitting machine device. In order to solve the above technical problem, the technical solution proposed by the present invention is:

[0010] A slitting machine device includes a slitting machine body, on which a wide-width coil installation portion and a slip shaft winding portion are provided. The wide-width coil installation portion is provided with a wide-width coil loading and unloading mechanism, and the slip shaft winding portion is provided with an automatic winding and unwinding mechanism. The slip shaft winding portion includes at least one slip shaft.

[0011] The wide-width coil material loading and unloading mechanism includes a movable chassis, a turntable and a rotating assembly for driving the turntable to rotate on the movable chassis, the turntable is connected to the movable chassis through the rotating assembly, and the turntable is provided with a wide-width coil material unwinding seat and a core removing assembly for removing the core of the wide-width coil material; the above-mentioned wide-width coil material loading and unloading mechanism is used to automatically load and unload wide-width coil materials at the wide-width coil material installation part, reducing manual operation.

[0012] The automatic winding and unwinding mechanism includes a base, a support frame, at least one unwinding assembly and at least one winding assembly. The support frame is arranged above the base, and the unwinding assembly and the winding assembly are both arranged on the support frame. The unwinding assembly is used to receive the coil from the differential shaft, and the winding assembly is used to install the winding paper roll on the differential shaft with high precision. Through the movement of the support frame, the position adjustment of the unwinding assembly and the winding assembly can be realized to realize the unwinding and winding functions. The number and height of the unwinding assemblies are the same as the number and height of the differential shafts, and the number and height of the winding assemblies are the same as the number and height of the differential shafts. Taking the unwinding assembly as an example, when there are two differential shafts, two unwinding assemblies are used, and the two unwinding assemblies correspond to the differential shafts at the installation position of the support frame respectively, so as to ensure that the height of the two unwinding assemblies corresponds to the height of the two differential shafts respectively.

[0013] In the above-mentioned slitting machine equipment, preferably, the core removal assembly includes a support, a manipulator and a manipulator driving source for driving the manipulator to clamp or relax, and the manipulator is installed on the turntable through the support.

[0014] In the above-mentioned slitting machine equipment, preferably, the manipulator includes an upper gripper part and a lower gripper part, the upper gripper part includes an upper gripper connecting arm and a pair of upper grippers arranged on both sides of the upper gripper connecting arm, and the lower gripper part includes a lower gripper connecting arm and a pair of lower grippers arranged on both sides of the lower gripper connecting arm; the manipulator driving source includes a driving part, a gear part and a transmission long shaft, the gear part includes a pair of upper gears and a pair of lower gears, the pair of upper gears and the pair of lower gears are connected through the transmission long shaft, the adjacent upper gears and lower gears are meshed and connected with each other, the two ends of the upper gripper connecting arm are respectively fixed on a pair of upper gears, the two ends of the lower gripper connecting arm are respectively fixed on a pair of lower gears, and the driving part is connected to the upper gear or the lower gear. The positions of the above-mentioned pair of upper grippers and the pair of lower grippers cooperate with each other so that the grippers at the upper and lower positions can cooperate with each other. The above-mentioned driving part is only connected to one upper gear or lower gear, for example, the driving part is connected to the lower gear on one side, and the power is transmitted to the lower gear on the other side through the transmission shaft. The upper gear serves as a driven gear, and its power comes from the lower gear. The two ends of the above-mentioned upper gripper connecting arm are respectively fixed to the inner side surfaces of a pair of upper gears (such as connected by bolts), and the upper gripper connecting arm is driven to rotate by the rotation of the upper gear, and then the upper gripper is driven to move downward. The two ends of the above-mentioned lower gripper connecting arm are respectively fixed to the inner side surfaces of a pair of lower gears, and the lower gripper connecting arm is driven to rotate by the rotation of the lower gear, and then the lower gripper is driven to move upward. Through the downward movement of the upper gripper and the upward movement of the lower gripper, the clamping or loosening of the manipulator can be achieved to remove the core of the wide-width coil from the inflatable shaft. In the present invention, considering that the diameter D of the empty core can be 75mm and the length L can be 800mm, a double-gear gripper is adopted, and the structure of the above-mentioned core removal assembly is simple, the transmission is clear, the operation is simple, and the advantages are obvious.

[0015] In the above-mentioned slitting machine equipment, preferably, a plurality of wheels and a wheel driving source for driving the wheels to move are provided below the movable chassis. The wheels and wheel driving source are mechanically driven light-duty working types, and the working speed can be 45m / min. A track is pre-laid below the above-mentioned movable chassis, and the track extends to the main body of the slitting machine. The above-mentioned wheel material can be ZG55, surface quenched, and the hardness is not less than 320-340HBS. In order to prevent the wheel from derailing, the wheel adopts a single wheel flange structure, and the wheel flange should be on the inner side of the track during installation. Four wheels are installed below the movable chassis, the two wheels located in the front are unpowered, and the wheels located at the rear are powered. Each wheel is independent and has two bearing seats fixed. Based on the different rotation speeds of the two wheels or possible vibrations, the driving wheel that provides power is not connected by a steel shaft, but is connected by a universal joint. One end of the universal joint is connected to the driving wheel to output motion, and the other end is connected to the large sprocket to input power. The wheel driving source is installed in the middle position at the bottom of the movable chassis, and the wheel movement is driven by chain drive. The present invention adopts the movable chassis, which has a simple structure and a safe and stable moving process.

[0016] In the above slitting machine equipment, preferably, the wide-width coil unwinding seat and the coring assembly are respectively arranged on both sides of the turntable, and the position of the rotating assembly is located between the wide-width coil unwinding seat and the coring assembly. Through the above arrangement, the positions of the wide-width coil unwinding seat and the coring assembly can be exchanged through the 180° rotation of the turntable, thereby realizing the processes of coring and installing the wide-width coil respectively.

[0017] In the above-mentioned slitting machine equipment, preferably, the wide-width coil unwinding seat includes two inclined steel plates, the inclination of the two steel plates is kept the same, and the area between the two steel plates is used to place the wide-width coil. The above-mentioned arrangement can ensure that the wide-width coil does not slip off the wide-width coil unwinding seat when the wide-width coil loading and unloading mechanism is started, stopped, or moved. In order to reduce weight, the wide-width coil unwinding seat is welded with aluminum alloy and can be used to place wide-width coils with a diameter D of 450 mm and a length L of 800 mm.

[0018] In the above slitting machine equipment, preferably, the rotating assembly includes a rotating bearing and a rotating motor, the rotating bearing is arranged between the movable chassis and the turntable, and the rotating motor can be installed on the turntable, located between the wide-width coil unwinding seat and the coring assembly. The above rotating assembly has a simple structure and a reasonable layout, and can easily meet the rotation requirements.

[0019] In the above-mentioned slitting machine equipment, preferably, the turntable can be made of a common steel plate, and a welded steel frame is installed at the bottom of the steel plate to improve the rigidity of the turntable.

[0020] In the above-mentioned slitting machine equipment, preferably, the automatic winding and unwinding mechanism also includes a rotating seat for driving the support frame to rotate, the rotating seat is movably arranged on the base, the support frame is arranged on the upper part of the rotating seat, and the unwinding assembly and the winding assembly are arranged on different sides of the support frame (that is, the unwinding assembly and the winding assembly are not arranged in parallel). The above-mentioned rotating seat is used to enable the support frame to rotate relative to the base to adjust the position correspondence between the unwinding assembly and the winding assembly and the slip shaft to realize the unwinding or winding function. A servo motor drives a pair of bevel gears inside the rotating seat. The axis of the rotating shaft of the horizontal servo motor is horizontal, and the bevel gear changes the axis of movement to vertical to realize the rotation of the support frame. The rotating seat can slide relative to the base to adjust the distance between the unwinding assembly or the winding assembly and the slip shaft. The sliding between the rotating seat and the base is realized by the following components: a base track and a rotating seat driving source for driving the rotating seat to move on the base track. The base track can adopt a linear guide rail, and the rotating seat driving source can adopt a servo motor plus a ball screw. The unloading assembly and the winding assembly are preferably arranged on different sides of the support frame, and there is a certain angle between the two, preferably, the angle between the two is not less than 90 degrees, so as to ensure that the unloading and winding functions do not interfere with each other. When multiple unloading assemblies and winding assemblies are used, every two adjacent unloading assemblies and winding assemblies are arranged at the same height, and the corresponding relationship between the unloading assembly and the winding assembly and the slip shaft can be adjusted by the rotating seat, and there is no need to adjust the height.

[0021] In the above-mentioned slitting machine equipment, preferably, the unloading assembly includes a support rod, and the support rod is arranged on the side of the support frame through a mounting seat, and a groove for inserting the end of the differential shaft is provided at one end of the support rod away from the mounting seat, and the size of the groove matches the size of the end of the differential shaft. The support rod is used to receive the coil from the differential shaft. When unloading the coil, since the movable support arm assembly needs to be lowered to facilitate moving the coil from the differential shaft to the support rod, at this time the differential shaft is only supported by the fixed-drive assembly, by providing a groove at the end of the support rod, when the support rod contacts the differential shaft, the end of the differential shaft will be inserted into the groove, which can play a role in supporting the differential shaft.

[0022] In the above-mentioned slitting machine equipment, preferably, the upper roll assembly includes a clamping part with adjustable clamping opening size, the clamping part includes a fixed arm and a movable arm, the fixed arm is fixedly connected to the support frame, the movable arm is rotatably connected to the fixed arm (such as connected by a pin shaft), and the clamping part is provided with a movable arm driving source for driving the movable arm to rotate; a baffle positioning mechanism is provided in the clamping opening of the clamping part, the baffle positioning mechanism includes a guide rod and a baffle, and the baffle is slidably arranged on the guide rod; the baffle positioning mechanism also includes a fixing part, a notch is provided on the movable arm, a through hole and a fixing hole are provided on the baffle, the baffle is slidably arranged on the guide rod through the through hole, and the fixing part passes through the notch and is inserted into the fixing hole to fix the positions of the baffle and the movable arm. The opening size of the clamping part can be achieved by driving the movable arm driving source to rotate the movable arm. When the opening of the clamping part is small, the clamping part clamps the paper tube. When the opening of the clamping part is large, the clamping part relaxes the paper tube, which is convenient for the clamping part to retreat from the main body of the slitting machine. The above-mentioned movable arm driving source can adopt a conventional driving device (such as a motor + gear). The above-mentioned fixed arm is fixedly connected to the support frame. In order to ensure the stability between the two, a support plate is provided between the fixed arm and the support frame. The baffle can be slidably moved on the guide rod, which can facilitate the adjustment of the distance between adjacent baffles, and then the position of the baffle is fixed by the fixing member, so as to facilitate the precise control of the installation accuracy of the paper tube. The fixing member can fix the baffle with the adjusted position to ensure the installation accuracy of the paper tube. The above-mentioned fixing member can adopt a screw rod, such as a screw hole is opened on the baffle, and the position of the baffle is fixed by the cooperation of the screw rod and the screw hole. When the distance between adjacent baffles needs to be adjusted, the screw rod can be loosened, and the position adjustment of the baffle is more convenient.

[0023] In the above-mentioned slitting machine equipment, preferably, the wide-width coil mounting part includes an inflatable shaft, an inflatable shaft mounting base plate, an inflatable shaft mounting bracket, an inflatable shaft mounting seat and an inflatable shaft driving source for driving the inflatable shaft mounting seat to move up and down, the inflatable shaft mounting base plate is provided with a horizontal track, the inflatable shaft mounting bracket is slidably arranged on the inflatable shaft mounting base plate along the horizontal track, the inflatable shaft mounting bracket is provided with a vertical track, the inflatable shaft mounting seat is slidably arranged on the inflatable shaft mounting bracket along the vertical track, and the inflatable shaft is arranged on the inflatable shaft mounting seat. The above-mentioned horizontal track is used to adjust the horizontal position of the inflatable shaft, and the vertical track is used to adjust the vertical position of the inflatable shaft. A slider can be provided at the bottom of the inflatable shaft mounting bracket to cooperate with the horizontal track, and a slider can also be provided on the inflatable shaft mounting seat to cooperate with the vertical track. By adopting the above-mentioned structure, the inflatable shaft can be moved in the horizontal and vertical directions, and the position of the inflatable shaft can be conveniently adjusted to make it easy to align with the core of the wide-width coil.

[0024] In the above slitting machine equipment, preferably, a positioning mechanism for fixing the position of the wide-width coil material loading and unloading mechanism is provided between the wide-width coil material installation portion and the wide-width coil material loading and unloading mechanism. The positioning mechanism is used to fix the position of the wide-width coil material loading and unloading mechanism, so as to ensure that when the turntable rotates and the coring and wide-width coil material installation processes are switched, the position of the wide-width coil material loading and unloading mechanism does not move, and the overall stability of the structure is better.

[0025] In the above-mentioned slitting machine equipment, preferably, the positioning mechanism includes a clamping part arranged on the movable chassis and a hook assembly arranged on the wide-width coil installation part for cooperating with the clamping part, the hook assembly includes a rotating arm, a rotating connecting column and a rotating arm driving source for driving the rotating arm to rotate, the rotating arm is arranged on the wide-width coil installation part through the rotating connecting column, and the shape of one end of the rotating arm close to the clamping part matches the shape of the clamping part.

When the wide-width coil loading and unloading mechanism reaches the specified position, the cylinder drives the rotating arm to rotate, and then the semicircular surface on the right hugs the cylindrical surface, so that the position of the wide-width coil loading and unloading mechanism can be fixed. When the wide-width coil loading and unloading mechanism needs to be moved, the cylinder drives the rotating arm to rotate away from the cylinder, so that the wide-width coil loading and unloading mechanism can be released.

[0026] In the above-mentioned slitting machine equipment, preferably, the slitting machine body is provided with a push plate assembly for pushing out and unloading the coiled material on the slip shaft, and the push plate assembly includes a push plate, a push plate track, and a push plate driving source for driving the push plate to move on the push plate track. The height of the above-mentioned push plate is preferably slightly lower than the height of the highest slip shaft, so that one push plate can achieve unloading of the coiled material on all slip shafts. The working process of the above-mentioned push plate driving source is as follows: the push plate is fixed to the push plate base by bolts, and four sliders are connected under the push plate base, which slide on the push plate track. Its power comes from the servo motor and converts the circular motion into linear motion through the ball screw.

[0027] In the above-mentioned slitting machine equipment, preferably, one side of the slip shaft is connected to the side plate of the slitting machine body through a fixed-drive assembly, and the other side of the slip shaft is connected to the side plate of the slitting machine body through a movable support arm assembly, and the movable support arm assembly includes a support arm and a support arm drive source for driving the support arm to move up and down; the automatic winding and unwinding mechanism is arranged on a side close to the movable support arm assembly. The fixed-drive assembly is used to fix and drive the slip shaft to rotate, and the rotation can be driven by a motor + gear. The movable support arm assembly can have two forms: supporting and lowering. When it is necessary to unload the roll and install the paper roll, the support arm is in a lowered form. When the unloading and installation of the paper roll are completed and the slitting machine body works normally, the support arm is in a supporting form. The above-mentioned support arm drive source can be a hydraulic cylinder or a pneumatic cylinder.

[0028] As a general technical concept, the present invention also provides a method for using the above-mentioned slitting machine equipment, and the automatic loading and unloading of wide-width coils includes the following steps:

[0029] S1: placing the wide-width coil on the wide-width coil unwinding seat of the wide-width coil loading and unloading mechanism;

[0030] S2: When the slitting of the main body of the slitting machine is completed and the wide-width coil needs to be replaced, the air shaft moves downward to the material replacement position, the wide-width coil loading and unloading mechanism moves toward the wide-width coil installation portion, and the coring assembly faces the wide-width coil installation portion. When the wide-width coil loading and unloading mechanism approaches the wide-width coil installation portion, the coring mechanism clamps the remaining core of the wide-width coil, and the air shaft moves outward to release the core;

[0031] S3: The rotating assembly of the wide-width coil loading and unloading mechanism drives the turntable to rotate, and adjusts the position of the air shaft so that the axis of the air shaft is aligned with the winding core of the wide-width coil. Then, the air shaft moves inward and is inserted into the winding core of the wide-width coil to fix the wide-width coil.

[0032] S4: The air shaft moves upward to the working position, and the slitting machine body starts the next slitting operation.

[0033] The automatic loading and unloading of wide-width coils includes the following steps:

[0034] S1: adjusting the distance between adjacent baffles as needed, and then placing the winding paper roll into the clamping part of the upper winding assembly;

[0035] S2: When the slitting of the main body of the slitting machine is completed and the roll needs to be unloaded, the support frame drives the unloading assembly to approach the winding part of the differential slip shaft, so that the support rod of the unloading assembly and the differential slip shaft are aligned and in contact (alignment means that the central axes of the two coincide), and under the push of the push plate assembly, the roll moves from the differential slip shaft to the support rod. During the movement of the roll, the support arm of the movable support arm assembly moves downward; when the unloading assembly is aligned with the differential slip shaft, the position of the unloading assembly is achieved by moving the support frame on the base, which can be completed with the help of conventional auxiliary positioning equipment;

[0036] S3: When the paper roll needs to be installed on the differential shaft after unloading, the push plate assembly retreats, the support frame rotates to make the paper roll on the upper roll assembly align with the differential shaft, and the support frame continues to drive the upper roll assembly to move toward the winding part of the differential shaft so that the paper roll is inserted into the differential shaft. At the same time, air is compressed in the differential shaft, and the differential ring supports the paper roll. Then the clamping part of the upper roll assembly releases the clamping force, and the support frame drives the upper roll assembly retreat; when the upper roll assembly is aligned with the differential shaft, the position of the upper roll assembly is achieved by moving the support frame on the base, which can be completed with the help of conventional auxiliary positioning equipment;

[0037] S4: The support arm of the movable support arm assembly rises upward, and the slitting machine body starts the next slitting operation.

[0038] In the present invention, the wide-width coil loading and unloading mechanism is moved to the vicinity of the wide-width coil installation part through a movable chassis, and the rotation of the turntable is driven by the rotating assembly to realize the process switching between coring and installing the wide-width coil. The wide-width coil loading and unloading mechanism in the present invention can easily realize the coring and installing wide-width coil processes, and the whole process realizes automated operation, with a high degree of intelligence, smooth operation, and simple steps. It can change the defect that workers are required to move wide-width coils in the past, omit most of the manual operations, and the labor intensity is significantly smaller. The parts of each part work together to reduce the standby time. The time for the slitting machine to stop slitting, wait for disassembly and installation of the wide-width coil is within one minute, which is more time-saving and labor-saving, and has higher work efficiency. In addition, due to the use of mechanical automation operation, precise control of the working process can be achieved. Through the cooperation of various components such as the positioning mechanism and the use of the feedback system, the inflatable shaft can be accurately inserted into the core of the wide-width coil to achieve precise installation of the wide-width coil.

[0039] The automatic winding and unwinding mechanism of the present invention changes the position correspondence of the unwinding assembly, the winding assembly and the slip shaft by moving and rotating the support frame in the steps of unloading and installing the paper tube to achieve different functions. When unloading, the mechanical parts are used to complete the automatic unloading function. Workers no longer need to move the rolls one by one from the slip shaft, which greatly reduces the labor intensity of the workers. When loading, the position of the paper tube is adjusted by the baffle to improve the installation accuracy of the paper tube. The whole process is closely connected, and the various parts work together to reduce the standby time. The work is highly automated and intelligent. The time for the slitting machine to stop slitting, wait for unloading and installation is less than one minute, which greatly improves the production efficiency. In the production work, the work that the workers need to complete is to remotely monitor the production status of the slitting machine and timely detect equipment failures that may occur during the production process. The labor intensity of the workers is low.

[0040] Compared with the prior art, the advantages of the present invention are:

[0041] 1. The wide-width coil loading and unloading mechanism of the present invention comprises a wide-width coil unwinding seat and a coring assembly. By adjusting the position of the turntable by rotating the assembly, the positional relationship between the wide-width coil unwinding seat and the coring assembly can be switched, so that the coring and wide-width coil installation processes can be easily realized. The entire coring and wide-width coil installation process requires less manual operation, has lower labor intensity, and has lower labor costs.

[0042] 2. The automatic winding and unwinding mechanism of the present invention comprises a winding unloading assembly and a winding loading assembly. By adjusting the positional relationship between the winding unloading assembly and the winding loading assembly, the winding unloading and winding loading functions can be conveniently realized. The entire winding unloading and winding loading process requires less manual operation and has lower labor intensity.
