Description

Technical Field

[0001] This utility model belongs to the technical field of airbag and air bag processing equipment, and in particular relates to an airbag and air bag rolling and folding device. Background Technology

[0002] Currently, in the production and processing of airbags and other airbag products, the rolling and forming of airbags mostly relies on manual operation or semi-automatic equipment. Manual rolling is not only inefficient and has poor consistency in rolling and forming, making it difficult to ensure that the airbag roll size is uniform and the tightness is appropriate, but also requires a lot of manual labor and cannot meet the needs of batch continuous production.

[0003] While some existing automated folding equipment can achieve a certain degree of air bag folding, their structures generally suffer from unreasonable layout and poor coordination between transmission and execution mechanisms. For example, the equipment and folding execution mechanism lack suitable space arrangement, and air bag wrinkles, deviations, and loose folding are prone to occur during the folding process.

[0004] For example, Chinese invention patent publication number CN107640338B, entitled "An Airbag Folding Cover Dust Cover Device," discloses an airbag folding cover dust cover device. This device integrates two separate devices—one for folding the airbag and the other for attaching the dust cover after folding—into one unit. The technical solution mentions that the airbag pre-compression mechanism includes a pre-compression cylinder, several pairs of pre-compression bearing seats, a pre-compression rotating shaft with bearings connected between the bearing seats, and a pre-compression tape wound on the pre-compression rotating shaft. The output shaft of the pre-compression cylinder is connected to the pre-compression rotating shaft via bearing transmission. The pre-compression tape... The material laying platform is laid flat along its length and its end is fixed to the front panel of the material laying platform. The first end of the airbag is rolled up in the rolling space formed by the first end of the pre-compression tape, the material laying platform, and the pre-compression shaft. However, the above configuration actually limits the types of airbag rolling. The width of the airbag varies depending on the vehicle model and installation location. Wider airbags require more stable compression and tension to ensure overall rolling accuracy and consistency, so as to meet the rolling processing requirements and operational stability of wide-width airbags.

[0046] The movable frame is connected to sliding fittings on both sides, and the sliding fittings are slidably engaged with the guide rail;

[0047] The two sides of the mobile frame are also connected to transmission connectors, which are connected to the tracked conveyor component so that when the tracked conveyor component rotates, the mobile frame is driven to move along the guide track through the transmission connectors.

[0048] The two sets of slide rail mechanisms are driven by the same long axis to achieve synchronous movement;

[0049] The servo motor drives the long shaft to rotate via a belt drive mechanism.

[0050] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0051] This solution first arranges multiple parallel folding belts at intervals on the equipment table and uses a support pressure roller mechanism to pull and tension the folding belts. This ensures that the airbags are subjected to uniform force during the folding process, effectively avoiding problems such as wrinkles, displacement, and loose folding of the airbags, and ensuring the consistency and regularity of the folding and forming of airbags of increased width.

[0052] In addition, by reserving a gap area between adjacent folding belts and setting folding grippers, the folding and clamping actions are arranged in a partitioned and orderly manner. After folding, the grippers can rise directly to clamp the air bag roll. The process is tightly connected, and no additional transfer or positioning is required, which significantly improves the automation level and processing efficiency of the folding operation.

[0053] Finally, the support roller mechanism is arranged in a row on the movable frame and is driven to move as a whole by the movable slide rail assembly, so that multiple folding belts can move synchronously, ensuring that the folding rhythm of each part of the airbag is uniform, the folding size is highly accurate, and it is suitable for stable mass production.

[0069] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0070] This equipment is a pure airbag and air bag rolling and folding equipment, without the dust cover mechanism. The overall layout has more redundant space to meet different production rhythms and process adjustments.

[0071] This utility model provides an airbag / airbag rolling and folding device to solve the problems of low rolling and folding efficiency, poor forming consistency, and easy wrinkling and displacement of airbags when the airbags / airbags have different specifications and larger widths. For specific technical solutions, please refer to [reference needed]. Figures 1 to 7 As shown, it includes:

[0072] The airbag / airbag folding device folds the airbag / airbag 1 using folding belts 2. It includes: a device platform 10, a movable frame 20, a support pressure roller mechanism 30, a movable slide rail assembly 40, and folding grippers 50. Multiple parallel folding belts 2 are laid at intervals on the device platform 10. The airbag / airbag 1 is unfolded and laid flat on the device platform 10, positioned above the folding belts 2. Multiple sets of support pressure roller mechanisms 30 are arranged in rows on the movable frame 20, and the support pressure roller mechanisms 30 are connected to the movable frame 20.

[0073] like Figure 3 The supporting pressure roller mechanism 30 shown in the figure is designed to ensure that the overall equipment can adapt to changes in the specifications of airbags and bags, especially when the width increases, in terms of folding accuracy and forming rate. In this solution, the supporting pressure roller mechanism 30 includes: a connecting component 310, which is fixedly connected to an actuating cylinder 340. The output end of the actuating cylinder 340 faces the equipment table 10. The connecting component 310 is a rigid component, and the output end of the actuating cylinder 340 is connected to a pressure roller component 320 to drive the pressure roller component 320 to perform lifting or pressing actions.

[0074] The pressure roller component 320 includes: an outer roller 323, an inner pressure roller 324, and a folding shaft 321;

[0075] The outer rollers 323 are rotatably connected to both sides of the pressure roller frame 322 and are used to continuously roll in a single direction on the surface of the airbag 1 when the moving frame 20 moves toward the first edge of the equipment table 10.

[0076] The inner pressure roller 324 is located at the lower end of the pressure roller frame 322 and is used to push and smooth the surface of the airbag 1 as it moves with the outer roller 323.

[0077] The folding shaft 321 is fixed on the pressure roller frame 322 and is located on the side opposite to the travel direction of the moving frame 20. The folding shaft 321 and the folding traction component 330 are used to cooperate in tensioning the folding belt 2.

[0078] The folding belt 2 is positioned below the inner pressure roller 324. After the folding belt 2 passes through the outer roller 323 and forms a shaft inside the pressure roller frame 322, it is positioned below the folding shaft 321. When the actuating cylinder 340 is raised, it forms traction tension. As the moving frame 20 moves, the actuating cylinder 340 is pressed down, causing the inner pressure roller 324 and the outer roller 323 to press against the surface of the airbag 1. The two work together to smooth the airbag 1, thereby improving folding efficiency and ensuring consistent forming. When the width of the airbag 1 increases, the stroke of the moving frame 20 will increase during the actual folding process. However, with the above configuration, it can significantly adapt to the folding of the airbag 1 with increased width. The outer roller 323 rolls continuously in one direction along the surface of the airbag 1 to compact the airbag 1 and avoid scratching the fabric of the airbag 1.

[0079] The folding gripper 50 extends vertically upward from the equipment table 10 after folding and clamps the air bag roll.

[0080] The folding belt 2 is pressed under the folding shaft 321 and connected to the folding traction component 330, so that the folding belt 2 is always kept taut during the pulling process. The folding belt 2 rises and falls synchronously with the pressure roller component 320 on this side of the pressure roller component 320, so that in the state of traction and tension, the folding belt 2 has a brief posture with an acute angle to the equipment table 10.

[0081] In a specific embodiment, such as Figure 1 , Figure 2 As shown, the other end of the folded belt 2 is fixed to the fastener 102 on the first edge, forming a single-sided fixation;

[0082] A reserved gap area 101 is formed between adjacent folding belts 2, and a set of folding grippers 50 is set in each reserved gap area 101.

[0083] The two ends of the movable frame 20 are slidably engaged with the movable slide rail assembly 40, which is used to drive the movable frame 20 to reciprocate along the direction of approaching or moving away from the first edge of the equipment table 10.

[0084] In one specific embodiment, the folding belt 2 passes through the gap formed on the pressure roller frame 322 by the mounting shafts of the inner pressure roller 324 and the outer roller 323, fits against the lower part of the folding shaft 321, and is connected to the folding traction component 330.

[0085] The arrangement height of the folding shaft 321 is greater than the arrangement height of the inner pressure roller 324.

[0086] The folding shaft 321 is rigidly fixed to the pressure roller frame 322 and does not rotate with the direction of travel of the pressure roller support mechanism 30. It only serves as the turning and tensioning fulcrum of the folding belt 2.

[0087] By placing the folding shaft 321 on the side of the pressure roller frame 322 opposite to the direction of travel, the pulling direction of the folding belt 2 can be made more reasonable, ensuring that the tension of the folding belt 2 is uniform, thereby making the folding process of the airbag 1 smoother and improving the folding accuracy.

[0088] In a specific embodiment, such as Figure 3 As shown, the connecting component 310 includes: a connecting body 311 and a limiting block 312;

[0089] The fixed end of the actuating cylinder 340 is located on the connecting body 311; a limiting block 312 is provided on one side of the connecting body 311. The limiting block 312 is used to limit the pressure roller frame 322 when the actuating cylinder 340 is actuated, so as to ensure its smooth movement.

[0090] In a specific embodiment, such as Figure 3 As shown, the folding traction component 330 includes: a folding traction frame 331, which is fixed on the connecting body 311 and located on the side opposite to the traveling direction of the connecting body 311; a roller sleeve 332 is rotatably connected to the folding traction frame 331, and a roller 333 is coaxially passed through the roller sleeve 332.

[0091] The roller sleeve 332 is rotatably connected to the folding traction frame 331 via a bearing, and can be driven to rotate by a separate drive assembly. The roller 333 is coaxially inserted inside the roller sleeve 332.

[0092] When a folding operation is performed towards the fixing member 102 at the first edge of the equipment table 10,

[0093] As the airbag is continuously rolled up, the rolling belt 2 is also continuously wound onto the roller sleeve 332. During the reverse reset action, the separate drive component drives the roller 333 to reverse, thereby releasing and resetting the rolling belt 2.

[0094] In a specific embodiment, such as Figure 4As shown, the lower section of the mobile frame 20 forms a traction arrangement space; the roller 333 is located in the traction arrangement space, and its two ends are rotatably connected to the mobile frame 20.

[0095] The airbag 1 passes around the roller sleeve 332 and is attached to one side of the roller sleeve 332 and is tensioned.

[0096] The roller 333 is connected to the first long shaft 360 through the roller belt drive mechanism 350. The first long shaft 360 is driven to rotate by the roller drive motor 370 through the first pulley drive mechanism 380.

[0097] The two ends of the roller 333 are rotatably connected to the inner side of the movable frame 20 through bearings to ensure smooth rotation of the roller 333; the airbag 1 passes around the radial direction of the roller sleeve 332 and is tensioned against the radial side of the roller sleeve 332 to achieve the positioning and guidance of the airbag 1.

[0098] The separate drive component is a roller drive motor 370. After the roller drive motor 370 is started, it drives the first long shaft 360 to rotate through the first pulley drive mechanism 380. The first long shaft 360 then drives the roller 333 to rotate synchronously through the roller belt transmission mechanism 350, which assists the airbag 1 in folding and feeding, and improves the folding efficiency.

[0099] In a specific embodiment, such as Figures 1 to 2 As shown, the reserved gap area 101 has a fixture working port 103;

[0100] like Figure 5 The mid-rolling gripper 50 includes: a gripping gripper 51 for gripping the air bag roll; a gripping gripper drive unit 52 for driving the gripping gripper 51 to perform the gripping action; a base 53 located below the equipment table 10; and a lifting cylinder 54 fixed to the base 53, the output end of which is connected to the gripping gripper drive unit 52. The gripping gripper 51 and the gripping gripper drive unit 52 can extend through the fixture working port 103 to above the equipment table 10.

[0101] A clamping working port 103 is provided on the reserved gap area 101. The clamping working port 103 is a through hole or notch adapted to the folding gripper 50. The base 53 of the folding gripper 50 is fixedly set below the equipment table 10. The lifting cylinder 54 is rigidly fixed on the base 53. The output end of the lifting cylinder 54 is fixedly connected to the gripper drive unit 52. The gripper 51 and the gripper drive unit 52 can extend to the top of the equipment table 10 through the clamping working port 103. The gripper drive unit 52 adopts a pneumatic or electric finger structure, which can drive the gripper 51 to perform opening and closing actions, thereby realizing the clamping of the air bag roll.

[0102] The gripping claw 51 has a binding strip on its inner side; when the air bag roll is above the working port 103 of the clamp, the lifting cylinder 54 and the gripping claw drive unit 52 can be controlled to move in a preset sequence so that the gripping claw 51 can clamp and fix the air bag roll.

[0103] Flexible binding strips are pasted or fixed on the inner side of the gripping claw 51 to prevent the gripping claw 51 from scratching the surface of the airbag 1 when gripping the airbag roll. When the airbag roll formed by the airbag 1 is moved above the working port 103 of the clamp, the control system controls the lifting cylinder 54 and the gripping claw drive unit 52 to perform driving actions in a preset sequence. First, the piston rod of the lifting cylinder 54 is controlled to extend, driving the gripping claw drive unit 52 and the gripping claw 51 to extend from the working port 103 of the clamp to both sides of the airbag roll. Then, the gripping claw drive unit 52 is controlled to move, driving the gripping claw 51 to close, so that the airbag roll is stably clamped and positioned by the gripping claw 51.

[0104] In a specific embodiment, such as Figure 4 , Figure 6 As shown, the movable slide rail assembly 40 includes two sets of slide rail mechanisms respectively arranged on both sides of the movable frame 20;

[0105] The slide rail mechanism includes a tracked conveyor component 410 and a set of guide rails 420 on both sides; the two sides of the movable frame 20 are connected to sliding engagement parts 230, which are in sliding engagement with the guide rails 420.

[0106] The two sides of the mobile frame 20 are also connected to transmission connectors 240, which are connected to the tracked conveyor component 410 so that when the tracked conveyor component 410 rotates, it drives the mobile frame 20 to move along the guide rail 420 through the transmission connectors 240; the two sets of slide rail mechanisms are driven by the same long shaft 430 to achieve synchronous movement; the servo motor 440 causes the long shaft 430 to rotate through the belt drive mechanism 450;

[0107] The movable slide rail assembly 40 includes two sets of slide rail mechanisms, which are symmetrically arranged on both sides of the movable frame 20. Each set of slide rail mechanisms includes a track-type conveyor component 410, and a set of guide rails 420 are respectively provided on both sides of the track-type conveyor component 410. Sliding fittings 230 are fixedly connected to both sides of the movable frame 20, and the sliding fittings 230 and the guide rails 420 form a sliding fit to guide the movable frame 20. Transmission connectors 240 are also fixedly connected to both sides of the movable frame 20, and the transmission connectors 240 are rigidly connected to the connecting ends of the track-type conveyor component 410. A long shaft 430 passes through the two sets of slide rail mechanisms and is used to control the synchronous rotation of the two sets of slide rail mechanisms. After the servo motor 440 is started, the long shaft 430 is rotated through the belt transmission mechanism 450. The long shaft 430 drives the track-type conveyor components 410 of the two sets of slide rail mechanisms to rotate synchronously, and then drives the movable frame 20 to move smoothly along the guide rails 420 through the transmission connectors 240 to ensure the running accuracy of the movable frame 20.
