Description

Technical Field

[0001] This invention belongs to the field of down jacket packaging technology, specifically relating to a winding device and winding method for down jacket production and packaging. Background Technology

[0002] In the production process of down jackets, it is often necessary to roll them up.

[0003] Existing technologies also include some solutions for down jacket winding, such as a Chinese patent with publication number CN116374348A. This patent discloses a winding device for down jacket production and packaging. By cooperating between two rotating rollers, the down jacket is squeezed, thus enabling a better winding operation. Furthermore, the two rotating rollers can be adjusted according to the actual condition of the down jacket during use, further facilitating subsequent winding operations. Under the action of a motor and corresponding transmission device, the rotation control of the two rotating rollers is completed, reducing the workload of workers, improving overall work efficiency, and demonstrating the device's overall stability, reliability, ease of adjustment, and practicality.

[0004] However, this patent still requires manually placing the down jacket between the two rotating rollers, which not only limits work efficiency but also poses a certain danger as workers may be caught in the machine during manual winding. Summary of the Invention

[0005] The purpose of this invention is to provide a winding device and winding method for down jacket production and packaging in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A winding device for packaging down jackets includes:

[0008] Two conveyors with the same conveying direction, both conveyors having the same height and a gap between them; and

[0009] The winding assembly includes a guide rail, a traction mechanism mounted on the guide rail, a slider mounted on the guide rail and connected to the traction mechanism, a rotating shaft passing through the slider and freely rotating and moving, a fixed plate and a moving plate mounted on the rotating shaft near one end of the conveyor, a gear mounted on the rotating shaft away from one end of the conveyor, an electric push rod mounted on the fixed plate for driving the moving plate, a rack mounted on the guide rail, and two baffles mounted on the guide rail. The moving plate is located at the interval and is at the same height as the conveying surface of the conveyor.

[0010] The conveyor transports the down jacket along its length to the winding assembly. The electric push rod moves the moving plate closer to the fixed plate, clamping the middle of the down jacket. The traction mechanism drives the slider, rotating shaft, fixed plate, moving plate, and down jacket to move upward along the guide rail. When the gear and rack mesh, they drive the rotating shaft and down jacket to rotate. Under the limit of the two baffles, the down jacket is wound up around the fixed plate and moving plate.

[0011] Preferably, the traction mechanism includes a traction motor, the output shaft of the traction motor is provided with a spool, a traction rope is provided on the spool, and the end of the traction rope away from the spool is connected to the slider.

[0012] Preferably, the fixed plate is provided with an air cylinder on the side near the moving plate, and the moving plate is provided with two oblique holes on the side near the fixed plate. Each of the two oblique holes is provided with a nozzle, and each nozzle is provided with an air pipe between itself and the air cylinder.

[0013] Preferably, a solenoid valve is provided inside the oblique hole.

[0014] Preferably, the guide rail is provided with an arc-shaped track, the rotating shaft is provided with a locking block, and the locking block is provided with a return spring for controlling the position of the rotating shaft.

[0017] S1: Place the down jackets at intervals on the conveyor so that they are arranged along their length;

[0018] S2: When the middle part of the down jacket moves to the winding assembly, the electric push rod on the fixed plate is activated. The electric push rod drives the moving plate to approach the fixed plate, so that the down jacket is clamped between the moving plate and the fixed plate. Then the traction mechanism is activated, which drives the slider, the rotating shaft, the fixed plate, the moving plate and the down jacket to move upward. When the gear and the rack contact, they drive the rotating shaft, the fixed plate, the moving plate and the down jacket to rotate. Under the limit of the two baffles, the down jacket is wound around the outside of the fixed plate and the moving plate.

[0019] S3: Remove the down jacket from the fixed plate and moving plate and put it into a packaging bag.

[0020] The beneficial effects of this invention are as follows:

[0027] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] like Figure 1-4 As shown, a winding device for packaging down jackets includes:

[0030] Two conveyors 1 with the same conveying direction, the two conveyors 1 having the same height and a gap 2 between them; and

[0031] The winding assembly includes a guide rail 3, a traction mechanism mounted on the guide rail 3, a slider 4 mounted on the guide rail 3 and connected to the traction mechanism, a rotating shaft 5 passing through the slider 4 and freely rotating and moving, a fixed plate 6 and a moving plate 7 mounted on the rotating shaft 5 near one end of the conveyor 1, a gear 8 mounted on the rotating shaft 5 away from the conveyor 1, an electric push rod 9 mounted on the fixed plate 6 for driving the moving plate 7 to move, a rack 10 mounted on the guide rail 3, and two baffles 11 mounted on the guide rail 3. The moving plate 7 is located at a gap 2 and is at the same height as the conveying surface of the conveyor 1.

[0032] It should be noted that the down jacket is placed on conveyor 1 with the collar facing the conveyor 1 in the direction of transport. Conveyor 1 is equipped with two sensors to receive the position information of the down jacket. Conveyor 1 transports the down jacket to the winding assembly. When the length of the down jacket on both conveyors 1 is the same, conveyor 1 is shut off. At the same time, the electric push rod 9 moves the moving plate 7 closer to the fixed plate 6, clamping the middle of the down jacket. Then, the traction mechanism drives the slider 4, rotating shaft 5, fixed plate 6, moving plate 7, and down jacket to move upward along the guide rail 3. After a period of idle movement, gear 8 contacts rack 10. When gear 8 meshes with rack 10, it drives rotating shaft 5 and down jacket to rotate. As the down jacket rotates on fixed plate 6 and moving plate 7, it contacts baffle 11. Under the limitation of the two baffles 11, the down jacket is wound up on fixed plate 6 and moving plate 7.

[0033] The traction mechanism includes a traction motor 12, with a spool 13 at the output shaft end of the traction motor 12. A traction rope 14 is mounted on the spool 13, and the end of the traction rope 14 away from the spool 13 is connected to a slider 4. The traction motor 12 drives the spool 13 to rotate, causing the traction rope 14 to be wound around the spool 13, thereby pulling the slider 4 upward. When a single down jacket is finished being rolled up and removed, the traction motor 12 reverses direction, and the slider 4 moves downward to its initial position under its own gravity, stretching the traction rope 14. The traction motor 12 is a servo motor, which is self-locking and highly sensitive, preventing changes in the position of the slider 4.

[0034] The guide rail 3 is equipped with an arc-shaped track 18, and the rotating shaft 5 is equipped with a locking block. A return spring 19, controlling the position of the rotating shaft 5, is mounted on the locking block. When the gear 8 moves to the arc-shaped track 18, it moves laterally along the track, causing the rotating shaft 5 to move laterally relative to the slider 4. This causes the fixed plate 6, the moving plate 7, and the down jacket to move laterally relative to the guide rail 3 and the conveyor 1, compressing the return spring 19. The lateral movement of the down jacket facilitates the bagging operation of the rolled-up down jacket by the workers. After bagging, as the slider 4 moves downward, the return spring 19 drives the rotating shaft 5 to move laterally back to its initial position, causing the moving plate 7 to return to the interval 2 between the two conveyors 1.

[0035] The surface of the arc-shaped track 18 is smooth, and the gear 8 can move easily on the surface of the arc-shaped track 18 without unnecessary rotation during the movement.

[0036] The guide rail 3 is equipped with a first hydraulic cylinder 20, and the baffle 11 is equipped with a second hydraulic cylinder 21. The output shaft end of the second hydraulic cylinder 21 is equipped with a clamping block 22 for holding the down jacket. The clamping block 22 is made of elastic rubber. The first hydraulic cylinder 20 and the second hydraulic cylinder 21 are connected by an oil pipe, with a solenoid valve in the middle of the oil pipe. The first hydraulic cylinder 20 is equipped with a counterweight 23 that extends it. The volume of the first hydraulic cylinder 20 is larger than that of the second hydraulic cylinder 21, so that the extension length of the second hydraulic cylinder 21 after the first hydraulic cylinder 20 is compressed is greater than the shortening length of the first hydraulic cylinder 20. When the slider 4 moves upward, it squeezes the first hydraulic cylinder 20, causing the liquid inside the first hydraulic cylinder 20 to enter the second hydraulic cylinder 21 through the oil pipe, thereby causing the second hydraulic cylinder 21 to extend. Hydraulic cylinder 21 (number two) drives clamping block 22 to grip the rolled-up down jacket. When slider 4 moves the fixed plate 6 and moving plate 7 back, clamping block 22 can still limit the down jacket, allowing it to be removed from the fixed plate 6 without manual intervention, further improving work efficiency. After slider 4 moves downward away from hydraulic cylinder 20 (number one), and the down jacket has been removed, the solenoid valve opens. Under the action of counterweight 23, hydraulic cylinder 20 (number one) extends, causing hydraulic cylinder 21 (number two) to shorten via fluid, and clamping block 22 returns to its initial position.

[0037] Example 2

[0038] The fixed plate 6 is provided with an air cylinder 15 on the side near the moving plate 7. The moving plate 7 is provided with two oblique holes 16 on the side near the fixed plate 6. Each of the two oblique holes 16 is provided with a nozzle 17. An air pipe is provided between each nozzle 17 and the air cylinder. When the moving plate 7 is close to the fixed plate 6, it will squeeze the air cylinder 15. The gas in the air cylinder 15 enters the nozzle 17 through the air cylinder and is sprayed out from the nozzle 17. The gas sprayed out from the nozzle 17 acts on the sleeves of the down jacket, causing the sleeves of the down jacket to be blown up and folded into the body of the down jacket, so that the sleeves will not detach from the body of the down jacket when the down jacket is rolled up.

[0039] An electromagnetic valve is installed inside the oblique hole 16. The electromagnetic valve is normally closed, and the gas entering the nozzle 17 from the first air cylinder 15 is temporarily stored in the nozzle 17. When the electromagnetic valve suddenly opens, a larger amount of gas is ejected from the nozzle 17, and the gas moves faster, allowing the sleeves to be folded up normally. For long down jackets, the folded position of the sleeves is exactly in the middle of the down jacket, and the moving plate 7 and the top plate can also press down the sleeves, further improving the fixation effect on the sleeves.

[0040] Example 3

[0041] A method for rolling up down jackets using the aforementioned down jacket production and packaging winding equipment includes the following steps:

[0042] S1: Place the down jackets at intervals 2 on the conveyor 1 so that they are arranged along the length direction;

[0043] S2: When the middle part of the down jacket moves to the winding assembly, the electric push rod 9 on the fixed plate 6 is activated. The electric push rod 9 drives the moving plate 7 to approach the fixed plate 6, so that the down jacket is clamped between the moving plate 7 and the fixed plate 6. Then the traction mechanism is activated, which drives the slider 4, the rotating shaft 5, the fixed plate 6, the moving plate 7 and the down jacket to move upward. When the gear 8 contacts the rack 10, it drives the rotating shaft 5, the fixed plate 6, the moving plate 7 and the down jacket to rotate. Under the limitation of the two baffles 11, the down jacket is wound around the outside of the fixed plate 6 and the moving plate 7.

[0044] S3: Remove the down jacket wrapped around the fixed plate 6 and the moving plate 7 and put it into a packaging bag.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
