Description

Technical Field

[0001] This utility model belongs to the field of air curtain folding technology, and in particular relates to an automatic side air curtain folding machine with a protective cover. Background Technology

[0002] Domestic consumers have increasingly higher requirements for the passive safety performance of automobiles. In addition to airbags, some higher-end vehicles are equipped with side curtain airbags. Side curtain airbags are safety devices located on the side of the vehicle. In the event of a collision, the side curtain airbags are inflated, and the inflated airbags can cover the window area between the A-pillar and C-pillar, protecting the occupants' heads and necks from impacts to the side of the door. In the production process of side curtain airbags, the rolling and forming and the application of protective covers are key post-processing steps that directly determine the safety of storage and transportation, as well as the convenience of subsequent assembly.

[0003] Currently, most side curtain processing in the industry adopts manual or semi-automated operation modes, which have many technical defects: First, the side curtain rolling and folding depends on manual operation. Operators need to manually position the side curtain hanging ears and pull the side curtain to roll and fold, which is not only labor-intensive but also inefficient. Second, the protective sleeve installation and rolling and folding processes are independent of each other. After rolling and folding, the side curtain needs to be manually transferred to the bagging equipment, resulting in a long process interval. Third, there are many manual intervention links, which not only increases the input of labor costs but also makes it easy for the side curtain to be scratched or damaged due to operator fatigue and operation errors, thus reducing the product qualification rate. Utility Model Content

[0004] In view of this, the present invention aims to provide an automatic side curtain folding machine for covering protective covers, which integrates the rolling and folding device with the bagging device in the upstream and downstream, eliminating the need for manual or separate equipment to transfer the side curtain between processes.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An automatic protective sleeve side curtain folding machine includes a folding device and a bagging device, wherein the bagging device is located downstream of the folding device.

[0007] The stacking device includes a stacking frame, a stacking motor, a stacking rod, a guide displacement mechanism, an inclined moving plate, an inclined motor, a side air curtain fixing plate, and a side air curtain fixing mechanism. The stacking motor is installed inside the stacking frame and located away from the bagging device. One end of the stacking rod is connected to the output end of the stacking motor. A groove is formed on the outer wall of the stacking rod along its axial direction. The middle of the other end of the stacking rod is recessed inward to form a guide groove. The output end of the guide displacement mechanism extends into the guide groove. The inclined moving plate is installed inside the stacking frame. The stacking motor and the guide displacement mechanism are respectively located at both ends of the inclined moving plate. The side air curtain fixing plate is installed inside the stacking frame and located on the inclined moving plate. The inclined moving plate is installed on the output end of the inclined motor. The inclined motor is fixed to the bottom end of the stacking frame. A positioning post is provided on the top surface of the side air curtain fixing plate. The side air curtain fixing mechanism is installed inside the stacking frame and located above the side air curtain fixing plate.

[0008] The bagging device includes a bagging frame, a bagging slide rail, a bagging electric cylinder, a bagging mechanism, a bagging rod, and a feeding mechanism.

The front and rear displacement beams are installed at the output ends of the front and rear drive cylinders. The vertical cylinder is installed on the front side of the front and rear displacement beams. The positioning pressure plate is located at the output end of the vertical cylinder. The vertical cylinder drives the positioning pressure plate to press against or move away from the side curtain airbag fixing plate.

[0012] Furthermore, the bagging mechanism includes a flipping motor, a bagging flipping plate, and sleeves. The flipping motor is installed inside the bagging machine frame and is offset from the bagging rod to avoid interference between the bagging rod and the flipping motor during operation. The bagging flipping plate is tilted, and one side of the bagging flipping plate is connected to the output end of the flipping motor. One end of each of the two sleeves is fixedly connected to the two ends of the other side of the bagging flipping plate. The upper sleeve faces the bagging rod, through which the bagging rod can pass, while the lower sleeve faces the feeding mechanism.

[0013] Furthermore, the bagging mechanism also includes bagging claws, a bagging claw synchronization cylinder, and a horizontal bagging cylinder. The two bagging claws are symmetrically arranged on the upper and lower sides of the upper sleeve. The two bagging claws are symmetrically installed at the output end of the bagging claw synchronization cylinder. The horizontal bagging cylinder drives the bagging claw synchronization cylinder to reciprocate in the horizontal direction.

[0014] Furthermore, the feeding mechanism includes a conveyor plate, a limiting plate, a feeding tray, and a tensioning wheel. The three conveyor plates are installed on the bagging machine frame, and the height of the conveyor plates is the same as the height of the axis of the lower sleeve. The two limiting plates are set at both ends of the top surface of one conveyor plate. The feeding tray is installed on the end of the bagging machine frame away from the flipping motor. The tensioning wheel is set between the feeding tray and the adjacent conveyor plate, and the tensioning wheel is located below the adjacent conveyor plate.

[0015] Furthermore, the feeding mechanism also includes feeding grippers, feeding gripper synchronization cylinders, feeding slides, lead screws, and drive motors. Two feeding grippers are symmetrically arranged on the upper and lower sides of the lower sleeve. The two feeding grippers are symmetrically arranged at the output end of the feeding gripper synchronization cylinders. The feeding gripper synchronization cylinders are mounted on the feeding slides. The feeding slides are threadedly connected to the lead screws, and one end of the lead screws is connected to the output end of the drive motors.

[0016] Furthermore, the feeding mechanism also includes a feeding pressure plate, a feeding cylinder, and pressure blocks. The feeding pressure plate is installed at the output end of the feeding cylinder, which is fixed inside the bagging machine frame. Two pressure blocks are symmetrically arranged on the bottom surface of the feeding pressure plate, and the two pressure blocks are located on both sides of the limiting plate near the sleeve.

[0018] (1) The equipment of this utility model realizes the automated operation of side air curtain from positioning and fixing, rolling and forming, to automatic feeding and putting on protective sleeve, without the need for manual operation of side air curtain rolling, protective sleeve putting and cutting; reducing manual operation links, reducing the labor intensity of operators, reducing operation errors caused by manual intervention, and reducing labor cost input.

[0019] (2) The guide support plate described in this utility model can prevent the side air curtain from drooping naturally and ensure that the side air curtain is rolled up in a flat state, effectively solving the problem of loose rolling in the traditional rolling method; at the same time, the inclined motor drives the inclined moving plate to move synchronously, so that the rolling rod moves closer to the side air curtain fixing mechanism synchronously during the rolling process, ensuring that the rolling trajectory is uniform and stable.

[0020] (3) The bagging device described in this utility model adopts a double-tube alternating operation mode. The flipping motor drives the bagging flipping plate to flip 180°, which can realize the synchronous operation of protective sleeve feeding and bagging process. There is no need to stop the machine to wait for feeding, which greatly improves the bagging efficiency.

[0021] (4) After the roll-up device of this utility model is completed, the guide displacement mechanism automatically moves out of the guide groove and moves down. The bagging device can be started without manual intervention, realizing the seamless connection between the roll-up and bagging processes and reducing the process interval time.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1 to 6 As shown, an automatic protective sleeve side curtain folding machine includes a folding device and a bagging device, with the bagging device located downstream of the folding device.

[0048] The stacking device includes a stacking frame 10, a stacking motor 11, a stacking rod 12, a guide displacement mechanism 13, an inclined moving plate 14, an inclined motor 15, a side air curtain fixing plate 16, and a side air curtain fixing mechanism 17. The stacking motor 11 is installed inside the stacking frame 10 and located away from the bagging device. One end of the stacking rod 12 is connected to the output end of the stacking motor 11. A groove 121 is formed on the outer wall of the stacking rod 12 along its axial direction. The other end of the stacking rod 12 is recessed inward to form a guide groove 122. The output end of the guide displacement mechanism 13 extends into the guide groove 122. The inclined moving plate 14 is installed inside the stacking frame 10. The stacking motor 11 and the guide displacement mechanism 13 are respectively located at both ends of the inclined moving plate 14. The side air curtain fixing plate 16 is installed inside the stacking frame 10 and located above the inclined moving plate 14. The inclined moving plate 14 is installed at the output end of the inclined motor 15. The inclined motor 15 is fixed. The bottom end of the roll-up frame 10 is fixed, and the top surface of the side air curtain fixing plate 16 is provided with positioning posts. The side air curtain fixing mechanism 17 is installed inside the roll-up frame 10 and is located above the side air curtain fixing plate 16. When the multiple hanging ears at the top of the side air curtain are hung on the corresponding positioning posts on the side air curtain fixing plate 16, the side air curtain fixing mechanism 17 works to press the top of the side air curtain onto the side air curtain fixing plate 16. The bottom end of the side air curtain is placed into the groove 121. The roll-up motor 11 drives the roll rod 12 to rotate and roll the side air curtain onto the roll rod 12. At the same time, the roll-up motor 11 and the guide displacement mechanism 13 move synchronously under the drive of the inclined moving plate 14 to roll the side air curtain onto the side air curtain fixing mechanism 17. The side air curtain fixing mechanism 17 releases the side air curtain and removes the hanging ears from the positioning posts to complete the side air curtain roll-up. After the roll-up is completed, the guide displacement mechanism 13 moves out of the guide groove 122 and moves down to prepare for the next process.

[0049] The bagging device includes a bagging frame 20, a bagging slide rail 21, a bagging electric cylinder 22, a bagging mechanism 23, a bagging rod 24, and a feeding mechanism 25. The bagging slide rail 21 is installed inside the bagging frame 20 and located in the middle of the bagging frame 20. The bagging electric cylinder 22 is mounted on the bagging slide rail 21 and moves along the length of the bagging slide rail 21. The bagging rod 24 is installed at the output end of the bagging electric cylinder 22. The bagging mechanism 23 is installed inside the bagging frame 20 and located in front of the bagging slide rail 21. The bagging mechanism 23 is located near the side air curtain fixing plate 16. The end of the bagging rod 24 away from the bagging electric cylinder 22 has a hook that passes through the bagging mechanism 23. The bottom of the bagging mechanism 23 faces the feeding mechanism 25. When the side air curtain is rolled up and the guide displacement mechanism 13 moves out of the guide groove 122 and down, the protective cover is already on the bagging mechanism 23. The bagging electric cylinder 22 drives the bagging rod 24 to pass through the bagging mechanism 23 and approach the rolling rod 12, so that the pull strap at the end of the side air curtain passes through the hook. The bagging electric cylinder 22 resets and drives the rolling rod 12 and the rolled-up side air curtain to pass through the bagging mechanism 23. When the end of the side air curtain passes through the bagging mechanism 23, the bagging electric cylinder 22 stops working and puts the protective cover already on the bagging mechanism 23 onto the side air curtain. The bagging electric cylinder 22 continues to work, driving the side air curtain and the protective cover on it to continue to move until the side air curtain and the protective cover slide off the bagging mechanism 23, completing the bagging work.

[0050] The output of the inclined motor 15 drives a threaded rod to rotate via a belt. One end of the threaded rod is rotatably mounted on the winding and stacking frame 10, and the other end is threadedly connected to a moving plate. Both ends of the moving plate are connected to the inclined moving plate 14 via connecting plates. When the inclined motor 15 rotates, it drives the moving plate to move via the threaded rod. The moving plate then drives the inclined moving plate 14 to move via the two connecting plates. Furthermore, the operation of the inclined motor 15 can drive the inclined moving plate 14 to work. Both ends of the inclined moving plate 14 can be respectively mounted on sliding rails, which are installed on the winding and stacking frame 10.

[0051] like Figure 1 , Figure 6 , Figure 8As shown, the guide displacement mechanism 13 includes a horizontal displacement guide rail 131, a horizontal displacement electric cylinder 132, a push cylinder 133, a guide seat 134, and a guide rod 135. The horizontal displacement guide rail 131 is installed on the inclined moving plate 14 near the end of the bagging frame 20. The horizontal displacement electric cylinder 132 is disposed on the horizontal displacement guide rail 131 and moves along the length of the horizontal displacement guide rail 131. The horizontal displacement guide rail 131 is arranged parallel to the winding rod 12. The push cylinder 133 is installed on the horizontal displacement electric cylinder 132, and the guide seat 134 is disposed on the push cylinder. At the output end of 133, the guide rod 135 is installed on the side of the guide seat 134 near the winding rod 12. After the guide displacement mechanism 13 and the winding motor 11 have finished winding the side air curtain, the horizontal displacement electric cylinder 132 works, which pushes the cylinder 133, the guide seat 134 and the guide rod 135 to move away from the winding rod 12. After the guide rod 135 moves out of the guide groove 122 on the winding rod 12, the horizontal displacement electric cylinder 132 stops working and pushes the cylinder 133 to work, which drives the guide seat 134 and the guide rod 135 to move downward, in preparation for winding the side air curtain again.

[0052] A guide support plate 18 is provided below the side air curtain fixing plate 16. The guide support plate 18 is parallel to the rolling direction of the roller rod 12. When the side air curtain's hanging ear is hung on the positioning post, the side air curtain is laid flat on the guide support plate 18 in preparation for rolling, thus preventing the side air curtain from drooping naturally and causing uneven rolling.

[0053] like Figure 1 , Figure 3 , Figure 7 As shown, the side curtain airbag fixing mechanism 17 includes a mounting plate 171, front and rear drive cylinders 172, front and rear displacement beams 173, a vertical cylinder 174, and a positioning pressure plate 175. The mounting plate 171 is installed inside the roll-up frame 10 and located above and behind the side curtain airbag fixing plate 16. The front and rear drive cylinders 172 are evenly installed on the top surface of the mounting plate 171. The front and rear displacement beams 173 are installed at the output ends of the front and rear drive cylinders 172. The vertical cylinder 174 is installed on the front side of the front and rear displacement beams 173. Positioning plate 175 is located at the output end of vertical cylinder 174. Vertical cylinder 174 drives positioning plate 175 to press or move away from side air curtain fixing plate 16. When the side air curtain's hanging ear is hooked on the positioning post, front and rear drive cylinder 172 drives front and rear displacement beam 173 to move above side air curtain fixing plate 16. Vertical cylinder 174 drives positioning plate 175 to move towards side air curtain and presses side air curtain onto side air curtain fixing plate 16, preventing side air curtain from shifting during the rolling process and ensuring the rolling effect.

[0054] like Figure 1 , Figure 4 , Figures 9 to 11As shown, the bagging mechanism 23 includes a flipping motor 231, a bagging flipping plate 232, and sleeves 233. The flipping motor 231 is installed inside the bagging frame 20. The flipping motor 231 is offset from the bagging rod 24 to avoid interference between the bagging rod 24 and the flipping motor 231 when the bagging rod 24 is working. The bagging flipping plate 232 is inclined. One side of the bagging flipping plate 232 is connected to the output end of the flipping motor 231. One end of each of the two sleeves 233 is fixedly connected to the two ends of the other side of the bagging flipping plate 232. The upper sleeve 233 is positioned towards the bagging rod 24, through which the bagging rod 24 can pass. The lower sleeve 233 is positioned towards the feeding mechanism 25. At this time, the lower sleeve 233 performs the work of putting on the protective sleeve. After the sleeve is put on, the flipping motor 231 drives the bag flipping plate 232 to rotate 180°, moving the sleeve 233 with the protective sleeve on to face the bag rod 24, in preparation for the work of putting on the protective sleeve. The bag electric cylinder 22 starts to work, and at this time, the lower sleeve 233 performs the work of putting on the protective sleeve.

[0055] The bagging mechanism 23 also includes bagging grippers 234, a bagging gripper synchronization cylinder 235, and a horizontal bagging cylinder 236. Two bagging grippers 234 are symmetrically arranged on the upper and lower sides of the upper sleeve 233. The two bagging grippers 234 are symmetrically mounted vertically on the output end of the bagging gripper synchronization cylinder 235. The horizontal bagging cylinder 236 drives the bagging gripper synchronization cylinder 235 to reciprocate horizontally. After the bagging rod 24 drives the rolled-up side air curtain through the upper sleeve 233, the horizontal bagging cylinder 236 drives the two bagging grippers 234 to move onto the sleeve. Above 233, two bagging claws 234, driven by a bagging claw synchronous cylinder 235, clamp the protective sleeve on the sleeve 233. A horizontal bagging cylinder 236 drives the two bagging claws 234 to move towards the bagging rod 24, moving the end of the protective sleeve out of the sleeve 233 and onto the rolled-up side air curtain. The bagging claw synchronous cylinder 235 drives the two bagging claws 234 to separate. The bagging electric cylinder 22 drives the bagging rod 24 to continue moving, bringing the protective sleeve out of the sleeve 233 through the rolled-up side air curtain. At the same time, the protective sleeve is placed on the rolled-up side air curtain.

[0056] The feeding mechanism 25 includes a conveyor plate 251, a limiting plate 252, a feeding tray 253, and a tensioning wheel 254. The three conveyor plates 251 are installed on the bagging machine frame 20. The height of the conveyor plates 251 is the same as the axial height of the lower sleeve 233. The two limiting plates 252 are set at both ends of the top surface of one conveyor plate 251. The feeding tray 253 is installed on the end of the bagging machine frame 20 away from the flipping motor 231. The tensioning wheel 254 is set between the feeding tray 253 and the adjacent conveyor plate 251. The tensioning wheel 254 is located below the adjacent conveyor plate 251. The protective sleeve on the feeding tray 253 is wound around the tensioning wheel 254 and fed into the three conveyor plates 251. It is limited by the limiting plate 252 to prevent the protective sleeve from separating from the conveyor plate 251 and to ensure that the protective sleeve is stably fed to the sleeve 233.

[0057] The feeding mechanism 25 also includes feeding grippers 255, feeding gripper synchronization cylinder 256, feeding slide 257, lead screw 258 and drive motor 259. Two feeding grippers 255 are symmetrically arranged on the upper and lower sides of the lower sleeve 233. Two feeding grippers 255 are symmetrically arranged at the output end of feeding gripper synchronization cylinder 256. Feeding gripper synchronization cylinder 256 is mounted on feeding slide 257. Feeding slide 257 is threadedly connected to lead screw 258. One end of lead screw 258 is connected to the output end of drive motor 259.

[0058] The opposing sides of the two bag-holding claws 234 and the opposing sides of the two feeding claws 255 are recessed inward to form arc-shaped grooves to accommodate the fitting tube 233 and the protective sleeve.

[0059] The bag-feeding gripper synchronous cylinder 235 and the feeding gripper synchronous cylinder 256 each have two built-in piston rods. The two piston rods move synchronously, causing the two bag-feeding grippers 234 and the two feeding grippers 255 to move closer or further apart.

[0060] The feeding mechanism 25 also includes a feeding plate 260, a feeding cylinder 261, and two pressing blocks 262. The feeding plate 260 is installed at the output end of the feeding cylinder 261, which is fixed inside the bagging machine frame 20. The two pressing blocks 262 are symmetrically arranged on the bottom surface of the feeding plate 260, and are located on both sides of the limiting plate 252 near the sleeve 233.

[0061] The protective sleeve tray is installed on the feeding tray 253. The end of the wound protective sleeve is wound onto the tension wheel 254 and passes through multiple conveyor plates 251 in sequence. At the same time, it is limited by the limiting plate 252. One end of the guide post is inserted into the protective sleeve. The guide post serves as a temporary auxiliary component to help the protective sleeve be fitted onto the sleeve 233 located below. The other end of the guide post is outside the protective sleeve. At this time, the two feeding jaws 255 work to clamp the guide post and the protective sleeve. The drive motor 259 works to drive the feeding slide 257 to move, extending the other end of the guide post into the sleeve 233. The two feeding jaws 255 move away from each other. The drive motor 259 drives the feeding slide 257 to move towards the upward pressure plate 260. Two feeding claws 255 are located near the end of the guide post. The two feeding claws 255 clamp the protective sleeve. The drive motor 259 drives the two feeding claws 255 to move towards the sleeve 233, so that the protective sleeve is placed on the sleeve 233 located below. The drive motor 259 reciprocates and the feeding claws 255 place the protective sleeve of the preset length on the sleeve 233. When the protective sleeve on the sleeve 233 reaches the preset length requirement, the feeding cylinder 261 works and drives the feeding pressure plate 260 to press the protective sleeve.
