Description

Technical Field

[0001] The present invention relates to the technical field of cloth winding devices, and in particular to a cloth continuous winding device and a winding method. Background Art

[0002] The existing cloth winding machine needs to stop when the cloth on the winding shaft reaches the specified thickness, put the winding shaft full of cloth on the conveyor belt for subsequent laminating and packaging, and install the new winding shaft on the winding device for winding. Before the cloth on the cloth unwinding shaft is finished, the above steps need to be repeated at least once. Therefore, the cloth winding process cannot be carried out continuously. The downtime is affected by the time to unload the full winding shaft, the time to replace the winding shaft, and the time to ensure the accurate initial winding of the new winding shaft, making it difficult to improve production efficiency. Summary of the invention

[0003] In view of the defects of the above-mentioned prior art, the present invention provides a continuous cloth winding device and a continuous cloth winding method to solve the problem of low production efficiency caused by the need to stop the machine to replace the winding shaft during the cloth winding process.

[0004] The technical solution of the present invention is as follows: A continuous cloth winding device comprises a punching device, a grabbing device and a winding shaft transmission device,

[0005] The punching device comprises a fixed roller and a punching shaft, wherein the fixed roller is used to support the cloth, the punching shaft is driven to rotate by a first rotary drive device and is provided with a dividing line tool and a positioning hole tool, the punching shaft is driven by a first lifting mechanism to approach or move away from the cloth, the punching shaft rotates when approaching the cloth and the dividing line tool and the positioning hole tool sequentially form a dividing line and a positioning hole on the cloth, the dividing line is a plurality of line segments extending along the width direction of the cloth and penetrating the cloth, and the positioning holes are a plurality of through holes arranged at intervals along the width direction of the cloth;

[0006] The grabbing device comprises a grabbing shaft, the grabbing shaft is driven to rotate by a second rotary drive device, the grabbing shaft is driven by a second lifting mechanism to approach or move away from the cloth, the grabbing shaft is provided with a grabbing rod, the angle between the grabbing rod and the axial surface of the grabbing shaft is variable, and the head end of the grabbing rod extends into the positioning hole so that the grabbing shaft grabs the cloth;

[0007] The winding shaft transmission device includes a circulating track and a plurality of winding shafts for winding up the cloth, the winding shaft moves along the circulating track and alternates between a first winding position and a second winding position; when the winding shaft at the first winding position is fully rolled up, the grabbing shaft grabs the cloth and moves toward the winding shaft at the second winding position so that the cloth is adhered to the winding shaft at the second winding position.

[0008] Furthermore, the fixed rollers are provided with a plurality of them, and the contact position of the dividing line cutter and the positioning hole cutter with the cloth is located between two adjacent fixed rollers. The dividing line cutter and the positioning hole cutter cut the cloth between the adjacent fixed rollers, so that the cloth has better support and a higher cutting success rate.

[0009] Furthermore, the dividing line cutter and the positioning hole cutter are arranged at different circumferential positions of the same punching shaft. Two sets of cutters are arranged on a single punching shaft, so that the spacing between the formed dividing line and the positioning hole is smaller, reducing the waste area of ​​the cloth. At the same time, the setting of a single punching shaft does not need to consider the interference problem between the cutters, and the structural complexity is low.

[0010] Furthermore, the end of the grabbing rod is hinged to the grabbing shaft, and a telescopic driving member is connected to one side of the grabbing rod, and the telescopic driving member drives the grabbing rod to swing along the winding movement direction of the cloth. Through the active control of the telescopic driving member, it can be ensured that the cloth is broken at the dividing line position, and the cloth is quickly released when the winding shaft at the second winding position is winding the cloth.

[0011] Furthermore, a sticky area is provided on the surface of the winding shaft, which can stably wind the cloth on the surface of the winding shaft when the cloth is initially wound.

[0012] Furthermore, the cloth continuous winding device includes a frame, and a sensor is provided on the frame. The sensor is used to detect the radius of the wound cloth on the winding shaft at the first winding position, and the sensor is a visual sensor or a distance sensor.

[0013] Furthermore, in order to facilitate the adjustment of the position of each winding shaft on the circulation track, the circulation track is provided with a rack arranged along the circulation path, and the end of the winding shaft is provided with a gear driven by a motor, and the gear is meshed with the rack.

[0015] Another technical solution of the present invention is: a continuous cloth winding method, based on the continuous cloth winding device, comprising: when the winding shaft at the first winding position is fully wound, the punching shaft approaches the cloth and rotates, and the dividing line tool and the positioning hole tool on the punching shaft sequentially form the dividing line and the positioning hole on the cloth toward the unwinding end of the cloth;

[0016] When the positioning hole reaches the corresponding position of the grabbing shaft, the grabbing shaft approaches the cloth so that the grabbing rod on the grabbing shaft extends into the positioning hole, and the winding shaft at the first winding position continues to wind the cloth so that the cloth is broken along the cutting line. At the same time, the punching shaft rotates an angle in the winding direction of the cloth so that one end of the cloth is mounted on the grabbing rod;

[0017] The grabbing shaft is close to the winding shaft of the second winding position. When the cloth mounted on the grabbing rod is wound by the winding shaft of the second winding position, the grabbing rod swings against the cloth winding direction to release the cloth, and the grabbing shaft returns to the initial position.

[0018] The winding shaft of the second winding position moves toward the first winding position during the winding process, and the winding shaft of the first winding position moves toward the second winding position after being replaced.

[0019] Furthermore, when the grabbing rod swings against the cloth winding direction to release the cloth, the grabbing shaft also rotates against the cloth winding direction.

[0020] The advantages of the technical solution provided by the present invention are:

[0021] Through the cooperation of the punching device, the grabbing device and the winding shaft transmission device, by forming a dividing line and a positioning hole, when the winding shaft at the first winding position is fully rolled, the cloth is pulled apart and the grabbing rod is used to mount the cloth so that the cloth is wound around the winding shaft at the second winding position. Therefore, when the winding shaft at the first winding position is replaced, the cloth unwinding does not need to be stopped, and the winding operation can be carried out continuously, thereby improving production efficiency.

[0033] The present invention is further described below in conjunction with examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0034] Please combine Figure 1 As shown, the cloth continuous winding device involved in this embodiment includes a frame, a punching device, a grabbing device and a winding shaft transmission device. The punching device, the grabbing device and the winding shaft transmission device are all installed on the frame. The punching device and the winding shaft transmission device are arranged front and back, and the grabbing device is located between the punching device and the winding shaft transmission device. The following describes each part separately.

[0035] Please combine Figures 2 to 4 As shown, the punching device includes a fixed roller 7, a punching shaft 2 and a first lifting mechanism 5a. A positioning hole cutter 1 and a segmenting hole cutter 3 are arranged on the punching shaft 2. In this embodiment, the positioning hole cutter 1 and the segmenting hole cutter 3 are installed on the same punching shaft 2 and are located on opposite sides of the punching shaft 2. The positioning hole cutter 1 is a plurality of circular hole cutters arranged axially at intervals along the punching shaft 2, and the segmenting hole cutter 3 is a dotted line cutter extending axially along the punching shaft 2. In some other embodiments, the positioning hole cutter 1 and the segmenting hole cutter 3 may be installed on one punching shaft 2 respectively.

[0036] There are at least two fixed rollers 7, which are horizontally installed on the frame 10, and the two fixed rollers 7 are separated by a certain distance, so that the punching shaft 2 can be located between the two fixed rollers 7, and at the same time prevent the positioning hole tool and the dividing hole tool from interfering with the fixed stick when the punching shaft 2 punches holes.

[0037] The first lifting mechanism 5a adopts a cylinder, which is connected to the first double-ear fixing seat 6a, and the first double-ear fixing seat 6a is horizontally installed on the outside of the frame 10. The first loading platform 8a is installed on the first lifting mechanism 5a on the left side of the outside of the frame 10. The first rotation drive device 9a is a motor, which is installed on the first loading platform 8a, and the output shaft of the motor is connected to one end of the punching shaft 2. The first bearing seat 4a is installed on the first lifting mechanism 5a on the right side of the outside of the frame 10, and the first bearing seat 4a and the other end of the punching shaft 2 are connected through a bearing. The first lifting chute 10a is respectively provided on both sides of the frame 10, and the two ends of the punching shaft 2 are inserted into the first lifting chute 10a. When the first lifting mechanism 5a drives the punching shaft 2 to rise and fall, the punching shaft 2 is guided by the first lifting chute 10a.

[0038] In the initial state, the punching shaft 2 is above the fixed roller 7 and away from the cloth. When punching and cutting are required, the first lifting mechanism 5a drives the punching shaft 2 to descend and approach the cloth supported by the fixed roller 7. The first rotary drive device 9a drives the punching shaft 2 to rotate, so that the positioning hole cutter 1 and the dividing hole cutter 3 are respectively in contact with the taut cloth to form positioning holes and dividing lines. The positioning holes are a number of through holes arranged at intervals along the width direction of the cloth, and the dividing lines are a number of line segments extending along the width direction of the cloth and penetrating the cloth. After the dividing lines are formed on the cloth, the cloth can be segmented along the dividing lines by tearing the cloth.

[0039] Please combine Figures 5 to 7 As shown, the grabbing device includes a grabbing shaft 12 and a second lifting mechanism 5b. The second lifting mechanism 5b adopts a cylinder, which is connected to a second double-ear fixing seat 6b. The second double-ear fixing seat 6b is horizontally installed on the outside of the frame 10. The second loading platform 8b is installed on the second lifting mechanism 5b on the right side of the outside of the frame 10. The second rotary drive device 9b is a motor, which is installed on the second loading platform 8b, and the output shaft of the motor is connected to one end of the grabbing shaft 12. The second bearing seat 4b is installed on the second lifting mechanism 5b on the left side of the outside of the frame 10, and the second bearing seat 4b and the other end of the grabbing shaft 12 are connected by a bearing. The second lifting chute 10b is respectively provided on both sides of the frame 10, and the two ends of the grabbing shaft 12 are inserted in the second lifting chute 10b. When the second lifting mechanism 5b drives the grabbing shaft 12 to rise and fall, the grabbing shaft 12 is guided by the second lifting chute 10b.

[0040] A plurality of grabbing rods 17 are mounted on the grabbing shaft 12, and the angle between the grabbing rods 17 and the axial circumference of the grabbing shaft 12 is variable, that is, the grabbing rods 17 can swing at a certain angle, so that the angle between the grabbing rods 17 and the axial circumference of the grabbing shaft 12 changes, and the swinging direction of the grabbing rods 17 is parallel to the cross section of the grabbing shaft 12. In this embodiment, a plurality of bases 14 are mounted on the grabbing shaft 12, and each base 14 is mounted with a grabbing rod 17, and the grabbing rods 17 are connected to the base 14 by a hinge, so that the grabbing rods 17 can rotate around the connection. A telescopic driving member 18 mounted on the base 14 is provided on one side of the grabbing rod 17 to drive the grabbing rod 17 to swing. In this embodiment, the base 14 is also connected to the first movable rocker 15 by a hinge, so that the first movable rocker 15 can rotate around the connection, and the two ends of the second movable rocker 16 are respectively hinged to the first movable rocker 15 and the grabbing rod 17.

[0041] Please combine Figures 8 to 11 As shown, the winding shaft transmission device includes a circulating track 20 and a plurality of winding shafts for winding cloth. In this embodiment, two winding shafts are configured, namely the first winding shaft 21 and the second winding shaft 22. The circulating track 20 is fixedly mounted on the inner side of the frame 10 by a fixing column 31. The circulating track 20 includes two layers of tracks, the outer side is an arc track with a rack, and the inner side is a smooth track. In this embodiment, the circulating track 20 is arc-shaped, and the outer position of the high point of the arc is defined as the first winding position, and the inner position of the low point of the arc is defined as the second winding position. In the figure, the first winding shaft 21 is located at the first winding position, and the second winding shaft 22 is located at the second winding position. The surfaces of the first winding shaft 21 and the second winding shaft 22 are provided with a sticky area. Both ends of the first winding shaft 21 and the second winding shaft 22 are mounted on the connecting frame 30, and one end thereof is connected to the motor 27. The specific connection method is that an outer gear ring 25 is provided at the end of the first winding shaft 21 and the second winding shaft 22, and an inner gear ring 26 is provided on the output shaft of the motor 27. The outer gear ring 25 is meshed with the inner gear ring 26, so as to facilitate the connection and separation of the first winding shaft 21 and the second winding shaft 22 from the motor 27. The connecting frame 30 is equipped with four track wheels 24 to cooperate with the circulating track 20. The connecting frame 30 is equipped with a gear 28 meshed with the rack on the rack arc track, and the gear 28 is driven by a servo motor 29, which is connected to the outer side of the connecting frame 30. When the servo motor 29 rotates, it drives the first winding shaft 21 and the second winding shaft 22 to move along the circulating track 20, so that the first winding shaft 21 and the second winding shaft 22 are alternately located at the first winding position and the second winding position.

[0042] In this embodiment, the frame 10 is also equipped with a sensor 19 for detecting the radius of the wound cloth on the winding shaft at the first winding position. The sensor 19 is a visual sensor. In some embodiments, the sensor 19 can be a distance sensor.

[0043] The winding method with the cloth continuous winding device of this embodiment includes:

[0044] When the sensor 19 detects that the cloth on the first winding shaft 21 is about to reach the specified thickness, it sends a signal to the control system, and the control system controls the first lifting mechanism 5a to push the punching shaft 2 downward along the first lifting slot 10a on the frame 10. When the cloth on the first winding shaft 21 reaches the specified thickness, the split hole cutter 3 on the punching shaft 2 contacts the taut cloth carried by the fixed roller 7 to leave a split line, and then the first rotary drive device 9a drives the punching shaft 2 to rotate 180°, and the positioning hole cutter 2 on the punching shaft 2 contacts the taut cloth to leave a positioning hole. During this process, the first winding shaft 21 continues to be wound, and the split line is closer to the first winding shaft 21 than the positioning hole. After the cutting of the positioning hole is completed, the first lifting mechanism 5a drives the punching shaft 2 to move up and return to the initial position.

[0045] When the punching shaft 2 is punching holes, the grabbing shaft 12 is driven by the second lifting mechanism 5b to move downward along the second lifting slot 10b on the frame 10, and the grabbing rod 17 on the grabbing shaft 12 contacts the cloth. The telescopic driving member 18 contracts to make the first movable rocker 15 and the second movable rocker 16 approximately straight, and the grabbing rod 17 forms the maximum angle with the axial surface of the grabbing shaft 12. When the cloth is continuously wound along with the first winding shaft 21, the head end of the grabbing rod 17 extends into the positioning hole so that the grabbing shaft 12 grabs the cloth. As the first winding shaft 21 is further wound, the cloth tension changes at this time. Due to the change in cloth tension, the cloth is evenly cut along the dividing hole.

[0046] The second lifting mechanism 5b further drives the grabbing shaft 12 to move downward along the second lifting slot 10b on the frame 10. In order to prevent the cloth from falling off the grabbing rod 17, the second rotary drive device 9b drives the grabbing shaft 12 to rotate in the cloth winding direction by no more than 180°. The descending speed of the grabbing shaft 12 is equal to the combined speed of its linear speed and the unwinding speed to ensure that the cloth tension remains unchanged.

[0047] The grabbing shaft 12 drives the cloth to move downward. When the cloth contacts the second winding shaft 22, the cloth sticks to the surface of the second winding shaft 22 and is wound by the second winding shaft 22. The telescopic driving member 18 extends to form an angle between the first movable rocker 15 and the second movable rocker 16. The angle between the grabbing rod 17 and the axial surface of the grabbing shaft 12 becomes smaller, and the grabbing rod 17 swings in the opposite direction of the cloth movement direction. At the same time, the grabbing shaft 12 is also driven by the second lifting mechanism 5b to move upward along the second lifting slot 10b on the frame 10 and is driven by the second rotary drive device 9b to rotate in the opposite direction of the cloth winding direction. The cloth is wound up by the second winding shaft 22 and separated from the grabbing rod 17.

[0048] After the first winding shaft 21 that has completed winding stops rotating, it is removed by a worker, thereby sending the first winding shaft 21 to the rear conveyor belt 23 to enter the subsequent film coating and packaging process. After the worker removes the first winding shaft 21 at the first winding position, a new first winding shaft 21 is installed at the first winding position. After the first winding shaft 21 is installed, its matching motor servo 29 is started, driving the first winding shaft 21 to move along the circulating track 20 to the second winding position. At the same time, the second winding shaft 22 that starts to wind the cloth moves along the circulating track 20 to the first winding position. During the entire cloth winding process, the above process is continuously carried out, thereby achieving the purpose of non-stop winding.
