Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, specifically to a precision packaging system and method for down jackets. Background Technology

[0002] The packaging of down jackets needs to achieve tight shaping in order to reduce warehousing and transportation costs. At present, the industry mostly uses semi-automatic packaging systems or simple fully automatic packaging systems with manual assistance in bagging and vacuum heat sealing to complete the packaging of down jackets.

[0003] However, in the existing packaging system, the frictional resistance between the fabric and the inner wall of the packaging bag is large during the down jacket insertion process, which can easily cause jamming and obstruction when pushing the material. This not only reduces the insertion efficiency but also easily causes the down jacket to wrinkle and deform, and the packaging bag to be damaged. At the same time, in the vacuum stage, the down is compressed by relying solely on negative pressure, which makes it easy for the down fibers to clump together and the internal air to be difficult to expel quickly, affecting the packaging efficiency and appearance.

[0004] To address these issues, a precision packaging system and method for down jackets are provided. Summary of the Invention

[0011] As a further optimization of the present invention, the ultrasonic module further includes a displacement unit, which is used to drive the arc-shaped seat to abut or separate from the first guide roller to achieve vibration transmission or avoid rotation; the displacement unit includes a fixed frame and a second spring column that movably passes through the fixed frame, and a movable frame for mounting the first ultrasonic transducer is fixedly provided at the end of the second spring column; the first spring column is movably passed through the movable frame, and the first ultrasonic transducer is fixedly provided at the end of the first spring column.

[0012] As a further optimization of the present invention, the displacement unit further includes a cam fixedly sleeved on the output shaft of the drive motor, and a guide wheel that is adapted to roll with the end face of the cam.

This effectively solves the problems of uneven down distribution and low air expulsion efficiency in the vacuum heat sealing stage of existing down jacket packaging. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings. 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.

[0020] Example 1 To address the issues of high frictional resistance between the down jacket and the packaging bag during the bagging process in existing down jacket packaging systems, leading to jamming and wrinkles, and uneven down distribution and low air removal efficiency during the vacuum heat sealing stage, please refer to [link to relevant documentation]. Figures 1-3 The present invention provides a precision packaging system and method for down jackets, comprising: Conveyor belt 1 is located on the top of the frame. Multiple packaging bag placement slots 101 and down jacket placement slots 102 are distributed alternately on the surface of the belt along the conveying direction. The periphery of the down jacket placement slot 102 is provided with a limiting chamber 103 for accommodating down jackets that have been manually pre-folded. The opening mechanism 2 is located on the frame and is used to open the opening end of the packaging bag; The pushing mechanism 4 is located on the frame upstream of the spreading mechanism 2 and is used to push the down jacket in the limiting chamber 103 into the spread packaging bag. At least one set of first ultrasonic components 3 are mounted on the frame between the spreading mechanism 2 and the pushing mechanism 4. They are used to provide vibration assistance during the process of the down jacket entering the packaging bag to reduce the resistance to entering the bag. Each set of first ultrasonic components 3 includes two ultrasonic modules respectively located on the upper and lower sides of the packaging bag. During the initial contact stage when the down jacket is pushed into the packaging bag, they provide instantaneous high-frequency micro-vibration to reduce the static friction between the surface of the down jacket and the inner wall of the packaging bag, thereby reducing the resistance to entering the bag and assisting the down jacket to enter the bag smoothly without jamming. Vacuum heat sealing assembly 5 is located on the frame downstream of the opening mechanism 2 and is used to vacuum and heat seal packaging bags containing down jackets. The second ultrasonic component 6 is located on the frame downstream of the vacuum heat sealing component 5, and there are two of them, which are respectively located on the upper and lower sides of the packaging bag, to assist the vacuum heat sealing component 5 in the air extraction operation.

[0021] Its working principle is as follows: The operator puts the pre-folded down jacket into the limiting chamber 103 and the packaging bag into the packaging bag placement slot 101. The conveyor belt 1 transports the down jacket and packaging bag to the bag entry station. The opening mechanism 2 opens the opening end of the packaging bag, and the pushing mechanism 4 pushes the down jacket into the packaging bag. During this process, the first ultrasonic component 3 is activated, and the rotating guide roller assists in the conveying. The intermittent ultrasonic vibration reduces the frictional resistance between the down jacket fabric and the inner wall of the packaging bag, so that the down jacket can be smoothly put into the bag and avoid jamming. After the bag is put into the bag, the conveyor belt 1 transports it to the vacuum heat sealing component 5. During the vacuuming process, the second ultrasonic component 6 is activated to help break up the down clumps, accelerate the air discharge and promote the uniform distribution of down. Finally, the bag is sealed by the vacuum heat sealing component 5.

[0022] Furthermore, the limiting compartment 103 includes a enclosure 104 and a movable cover 105 hinged to the top of the enclosure 104. The movable cover 105 is used to flatten and limit the down jacket before pushing the material. In use, the movable cover 105 is opened, the operator puts the pre-folded down jacket into the enclosure 104, and then the movable cover 105 is closed to fix the down jacket.

[0023] Specifically, such as Figure 4As shown, the spreading mechanism 2 includes a lower fixed adsorption seat 201, an upper movable adsorption seat 202, a mounting plate 203, and a first lifting drive component 204 for driving the mounting plate 203 to rise and fall. The first lifting drive component 204 is fixed to the frame by a bracket. Specifically, the first lifting drive component 204 can be a cylinder. The lower fixed adsorption seat 201 is fixedly mounted on the frame and located below the conveyor belt 1. A through hole is opened at a corresponding position on the conveyor belt 1. The upper movable adsorption seat 202 is fixedly mounted on the mounting plate 203, and the lower fixed adsorption seat 201 and the upper movable adsorption seat 202 are respectively located on both sides of the packaging bag. In the first ultrasonic component 3, the upper ultrasonic module is fixedly mounted on the mounting plate 203 and rises and falls synchronously with the upper movable adsorption seat 202, while the lower ultrasonic module is fixedly mounted on the frame.

[0024] In use, the lower fixed adsorption seat 201 and the upper movable adsorption seat 202 adsorb the upper and lower side walls of the packaging bag respectively. The first lifting drive component 204 drives the upper movable adsorption seat 202 to rise and open the bag opening.

[0025] Optionally, the pushing mechanism 4 includes a pusher 401, a pusher plate 402 fixedly disposed at the end of the pusher 401, a first moving module 403 for driving the pusher 401 to move horizontally, and a second lifting drive 404 for driving the first moving module 403 to move up and down. The second lifting drive 404 is fixed on the frame by a bracket, and its output end is connected to the first moving module 403 in a transmission connection. The output end of the first moving module 403 is connected to the pusher 401 in a transmission connection. Specifically, the first moving module 403 can be a lead screw module, and the second lifting drive 404 can be a cylinder.

[0026] When the pushing mechanism 4 is in use, the second lifting drive component 404 adjusts the height, and the first moving module 403 drives the push plate 402 to move horizontally forward to push the down jacket into the bag.

[0027] Specifically, such as Figure 5 As shown, the ultrasonic module includes two bearing seats 301, a first guide roller 302 rotatably disposed between the two bearing seats 301, a drive unit for driving the first guide roller 302 to rotate, and an ultrasonic unit for driving the first guide roller 302 to vibrate; the drive unit includes a drive motor 305, a drive gear 304 fixedly sleeved on the output shaft of the drive motor 305, and a driven gear 303 fixedly sleeved on the rotating shaft of the first guide roller 302, the driven gear 303 meshing with the drive gear 304; the ultrasonic unit includes a first ultrasonic transducer 306 and an arc-shaped seat 307 fixedly disposed at the end of the amplitude rod of the first ultrasonic transducer 306, the arc-shaped seat 307 abutting against the first guide roller 302 to transmit vibration.

[0028] In practical use, the drive motor 305 drives the driven gear 303 to rotate via the active gear 304. The driven gear 303 then drives the first guide roller 302 to rotate. Simultaneously, the first ultrasonic transducer 306 is activated, generating high-frequency vibration. This vibration is transmitted to the arc-shaped seat 307 via the amplitude transformer at its output end. Since the arc-shaped seat 307 maintains contact with the outer surface of the first guide roller 302, the vibration energy is coupled to the first guide roller 302. The rotating first guide roller 302 provides a conveying assist force for the down jacket, while the synchronously transmitted ultrasonic vibration acts on the contact surface between the down jacket fabric and the inner wall of the packaging bag, significantly reducing the frictional resistance between them. This ensures that the down jacket smoothly enters the packaging bag under the pusher mechanism 4, avoiding jamming or fabric damage.

[0029] Specifically, such as Figure 6 As shown, the second ultrasonic component 6 includes an inner mounting frame 601, a second guide roller 602 rotatably disposed within the inner mounting frame 601, an outer mounting frame 604, and a second ultrasonic transducer 603 fixedly disposed within the outer mounting frame 604 for driving the inner mounting frame 601 to vibrate. One end of the inner mounting frame 601 is fixedly connected to the end of the amplitude transformer of the second ultrasonic transducer 603, and the other end is elastically connected to the outer mounting frame 604. A top plate 605 is provided above the outer mounting frame 604, and a third spring column 606 is movably passed through the top plate 605. The outer mounting frame 604 is fixedly disposed at the bottom end of the third spring column 606. A second moving module 607 for driving the second ultrasonic component 6 to move along the surface of the packaging bag is provided above the top plate 605. The second moving module 607 is fixed on the frame by a bracket. The second moving module 607 can be a lead screw module.

[0030] In specific use, when the packaging bag containing the down jacket is transported to the vacuum heat sealing station, the vacuum heat sealing component 5 first clamps and seals the bag opening area through its upper movable seat and lower fixed seat, and starts the air extraction operation. At this time, negative pressure begins to form inside the bag, and the down jacket gradually collapses and compresses under atmospheric pressure. At the same time, the two second ultrasonic components 6 located on the upper and lower sides of the packaging bag work synchronously and move horizontally along the upper and lower surfaces of the packaging bag to achieve dynamic scanning vibration assistance for different areas of the down jacket. In this embodiment, the running directions of the two are preferably opposite.

[0031] The second ultrasonic transducer 603 generates high-frequency vibration, which is transmitted to the inner mounting frame 601 via its amplitude transformer. This drives the second guide roller 602, which is located inside the inner mounting frame, to generate micro-vibration. Since the second guide roller 602 is in direct contact with the outer surface of the packaging bag, and one end of the inner mounting frame 601 is rigidly connected to the second ultrasonic transducer 603 while the other end is elastically connected to the outer mounting frame 604, the vibration energy can be efficiently and stably transmitted to the down filling layer inside the bag. At the same time, the third spring column 606 provides constant pre-pressure to ensure that the second guide roller 602 always fits against the bag surface. Even during the process of bag collapse and deformation, it can maintain effective vibration transmission. Under the action of vibration, the agglomerated structure between down fibers is disturbed and disintegrated. The trapped air is released from the fiber gaps and flows quickly to the air extraction port, significantly shortening the air extraction time. In addition, the vibration promotes the distribution of down to be more uniform.

[0032] It should be noted that the vacuum heat sealing component 5 is an existing module in conventional automated packaging equipment in the field. It typically includes an air extraction pipeline, a vacuum pump, upper and lower heat sealing blades, a sealing pressure plate, and corresponding drive and temperature control systems. It can vacuum the packaging bag containing down jackets and complete the heat sealing operation. Since the structure and working principle of this component are well known in the prior art and are not the focus of the improvement of this invention, its specific structure and control logic will not be described in detail here.

[0033] Example 2 Based on Embodiment 1, in order to achieve controllable contact and separation between the arc-shaped seat 307 and the first guide roller 302, and to ensure the reliability and efficiency of ultrasonic vibration transmission, as follows: Figure 5 As shown, the ultrasonic module also includes a displacement unit, which is used to drive the arc-shaped seat 307 to abut or separate from the first guide roller 302 to achieve vibration transmission or avoid rotation; the displacement unit includes a fixed frame 310 and a second spring column 311 that movably passes through the fixed frame 310. The end of the second spring column 311 is fixedly provided with a movable frame 308 for mounting the first ultrasonic transducer 306; the first spring column 309 is movably passed through the movable frame 308, and the first ultrasonic transducer 306 is fixedly provided at the end of the first spring column 309.

[0034] The displacement unit also includes a cam 313 fixedly sleeved on the output shaft of the drive motor 305, and a guide wheel 312 that is adapted to roll with the end face of the cam 313. The guide wheel 312 is fixedly mounted on the moving frame 308. The drive gear 304 is an incomplete gear to control the rotation of the first guide roller 302 and make it stop periodically.

[0035] During use, as the drive gear 304 drives the first guide roller 302 to rotate, since the drive gear 304 is an incomplete gear, the first guide roller 302 will periodically stop at a preset position after rotating a certain angle. When the first guide roller 302 stops, the cam 313 fixed on the output shaft of the drive motor 305 rotates synchronously to the descent section, causing the guide wheel 312 and the movable frame 308 connected to it to retract axially along the second spring column 311, thereby pressing the arc seat 307 against the outer surface of the first guide roller 302. At this time, the high-frequency vibration generated by the first ultrasonic transducer 306 is amplified by the amplitude transformer and transmitted to the first guide roller 302 by the arc seat 307. Since the first guide roller 302 is in a stationary state, the vibration energy is efficiently coupled to its surface and acts on the down jacket in contact with it. Under the assistance of vibration, the fibers on the surface of the down jacket produce a slight shaking, which effectively weakens the static friction and adhesion effect between it and the inner wall of the packaging bag, significantly reduces the pushing resistance, and avoids jamming, wrinkles or tearing of the bag opening.

[0036] After vibration is completed, as the cam 313 continues to rotate to the lifting section, under the action of the first spring column 309 and the second spring column 311, the arc-shaped seat 307 automatically disengages from the first guide roller 302 so as not to affect its subsequent rotation. Then the above process is repeated. The ultrasonic module achieves intermittent ultrasonic assistance with high vibration transmission efficiency through the coordinated mechanism of rotation, stopping, contact, vibration and separation.

[0037] Example 3 This invention also provides a method for precise packaging of down jackets, comprising the following steps: S1. The pre-folded down jacket is placed into the limiting chamber 103, and the packaging bag is placed into the packaging bag placement slot 101 and conveyed synchronously with the conveyor belt 1. S2. The opening end of the packaging bag is opened by the opening mechanism 2; S3. During the process of the down jacket entering the packaging bag, the first ultrasonic component 3 is activated to provide vibration assistance to reduce the resistance to entering the bag. At the same time, the pushing mechanism 4 pushes the down jacket in the limiting chamber 103 into the opened packaging bag. S4. After the down jacket is completely placed in the bag, the vacuum heat sealing component 5 performs vacuuming and heat sealing on the packaging bag. During the air extraction stage of the vacuum heat sealing component 5, the second ultrasonic component 6 is activated to apply vibration to the upper and lower sides of the packaging bag to help break up the down clumps, accelerate the air expulsion, and promote uniform filling.

[0038] 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.
