Description

Technical Field

[0002] Alumina is an inorganic compound widely used in many industries. It has the appearance of white amorphous powder or crystals with fine texture. As a material widely used in many industries, the choice of packaging method for alumina powder is crucial to ensure product quality, transportation safety and operational convenience. Ton bags can hold materials ranging from hundreds of kilograms to more than one ton, which is very suitable for large-scale transportation and storage of alumina powder. Compared with small packages, ton bags can more effectively utilize the space of warehouses or transportation tools and reduce unit costs. However, when alumina powder is currently packaged in ton bags, the ton bag is manually put on the discharge pipe of the packaging machine, and the clamping mechanism of the packaging machine clamps and fixes the ton bag mouth. Finally, the packaging machine fills the ton bag with alumina powder. However, this kind of manual bagging operation on the packaging machine is inefficient and has certain safety risks. Therefore, in order to improve the packaging efficiency of alumina powder and reduce safety risks, this scheme designs an automatic production line for ton bag packaging. Summary of the invention

[0080] The specific implementation process is as follows:

[0081] When the feeding bin 1 is in use, the ton bags are manually stacked on two pallets 105. At this time, one of the feeding cylinders 103 is started through the controller, and the output shaft of the feeding cylinder 103 begins to extend. When the output shaft of the feeding cylinder 103 extends, the pallet 105 is driven to move on the slide rail. When the pallet 105 moves to the specified position, the baffle 109 is exactly located at the position sensor 107. After the position sensor 107 detects the baffle 109, it transmits a signal to the controller. At this time, the controller controls the feeding cylinder 103 to stop running, and the pallet 105 remains in a stable state, waiting for the pallet 105 to move to the specified position. After the ton bags on the pallet 105 are used up, the infrared sensor detects that there are no ton bags on the pallet 105. At this time, the infrared sensor transmits the monitoring signal to the controller. At this time, the controller controls the output shaft of the feeding cylinder 103 under the pallet 105 to shrink. When the output shaft of the feeding cylinder 103 shrinks, it drives the pallet 105 to move to the original position. The position sensor 107 at this position detects the baffle 109 on the pallet 105 and transmits the monitoring signal to the controller. At this time, the controller controls the feeding cylinder 103 to stop running, and then the workers can replenish the ton bags on the pallet 105. While the pallet 105 returns to its original position, the controller controls the output shaft of another feeding cylinder 103 to extend, and drives another pallet 105 to move to the designated position through the output shaft of the feeding cylinder 103 to replenish the ton bags to avoid the shortage of ton bags. In this way, the two pallets 105 are fed alternately.

[0082] When the bag holding device 2 is in use, after the suction cup 302 on the mechanical arm 309 sucks up the ton bag and exposes the bag opening, the controller controls the motor 220 to start. When the motor 220 is running, it drives the driving gear 1 located above the support plate 206 to rotate. When the driving gear 1 rotates, it drives the ring chain 218 to move. When the ring chain 218 moves, it pulls the base plate 210 to move vertically up and down on the support plate 206. When the height of the base plate 210 is the same as the height of the bag opening of the ton bag, the controller controls the motor 220 to stop running, and then starts the motor 1 219. When the motor 1 219 is running, it drives the traditional gear to rotate. When the transmission gear 1 208 rotates, it drives the chain 407 to move. When the chain 407 moves, it drives the moving plate 204 to move toward the bag opening of the ton bag. Since the support plate 206 is fixedly connected to the moving plate 204, a circular plate 212 is fixed on the support plate 206 through the connecting plate 211. The circular plate There are four support rods 213 rotatably connected on the circumference of 212, which are evenly spaced. Therefore, when the movable plate 204 moves, the support rods 213 are driven to move synchronously until the support rods 213 are inserted into the bag opening of the ton bag. At this time, the controller stops the operation of the motor 219, and then starts the bag-supporting cylinder to extend the output shaft of the bag-supporting cylinder. When the output shaft of the bag-supporting cylinder extends, the linkage plate 214 is pushed to move in the extension direction of the output shaft of the bag-supporting cylinder. When the linkage plate 214 moves, the four linkage rods 215 gradually change from an inclined state to a state perpendicular to the support rods 213. At this time, the four support rods 213 are propped up by the linkage rods 215, so that the distance between the support rods 213 and the support rods 213 increases. As the distance between the support rods 213 and the support rods 213 increases, the support rods 213 open the bag opening of the ton bag, making the bag opening rectangular, which is convenient for the robot arm 309 of the next process to clamp the ton bag. After the ton bag mechanical arm 309 clamps, the controller controls the output shaft of the bag-supporting cylinder to shorten. When the output shaft of the bag-supporting cylinder shortens, the linkage plate 214 is driven to return to its original position. The linkage plate 214 pulls the linkage rod 215 in the process of returning to its original position. Then the linkage rod 215 gradually turns into an inclined state due to the vertical state of the support rod 213. In this process, the linkage rod 215 pulls the support rod 213 toward the center. At this time, the support rod 213 is separated from the bag mouth of the ton bag. Then the controller controls the motor 1 219 to start in reverse. When the motor 1 219 runs in reverse, it drives the moving plate 204 to return to its original position on the rectangular frame 202, and then drives the support rod 213 to be taken out of the bag mouth of the ton bag. When the substrate 210 moves vertically up and down on the support plate 206, the two limit sensors 205 monitor the position of the substrate 210. When it basically moves to the limit sensor 205, the limit sensor 205 transmits the monitoring signal to the controller, and the controller immediately stops the operation of the motor to stop the movement of the substrate 210.

[0083] When the robot arm gripper 3 is in operation, the visual sensor 308 first photographs and locates the ton bag on the pallet 105 of the feeding bin 1, and then transmits the signal to the controller. At this time, the controller controls the robot arm 309 to drive the connecting piece 301 to move to the top of the ton bag, and then the controller drives the connecting piece 301 downward through the robot arm 309 until the suction cup 302 contacts the bag opening of the ton bag. At this time, the controller controls the air pump to operate so that the suction cup 302 generates negative pressure to suck the bag opening of the ton bag. After the ton bag is sucked by the suction cup 302, the robot arm 309 drives the connecting piece 301 to move upward. At this time, the sucked part of the bag opening of the ton bag is pulled up, and the unsucked part naturally droops under the action of gravity so that the bag opening faces the bag-supporting device 2. After the support rod 213 of the bag-supporting device 2 is inserted into the bag opening of the ton bag and opens the bag opening to make the bag opening rectangular, the air pump stops running, so that the suction cup 302 no longer generates negative pressure, and the robot arm 309 The connecting piece 301 is driven to rotate so that the two clamping rods 304 are on the same vertical plane. The controller controls the output shaft of the clamping cylinder 306 to extend so that a gap of a certain distance is formed between the clamping plate 305 and the clamping plate 307. The mechanical arm 309 runs through the connecting piece 301 and the clamping rod 304 to drive the two clamping plates 305 to move. The gaps between the two clamping plates 305 and the two clamping plates 307 are inserted into the upper and lower edges of the supported rectangular bag opening. At this time, the controller controls the output shaft of the clamping cylinder 306 to contract. When the output shaft of the clamping cylinder 306 contracts, it drives the clamping plate 307 to move toward the clamping plate 305 until the clamping plate 307 and the clamping plate 305 firmly clamp the bag opening of the ton bag. At this time, the support rod 213 of the bag supporting device 2 withdraws from the bag opening of the ton bag, and the controller controls the mechanical arm 309 to drive the connecting piece 301 to move, so that the bag opening of the ton bag is connected to the discharge pipe of the packaging machine.

[0084] When it is necessary to hang the sling of the ton bag on the hook of the packaging machine, start the driving motor 401 of the two sling assemblies. When the driving motor 401 is running, the lifting plate 410 is lowered to the bottom of the cam frame 402, and then the four sling cylinders 413 are started synchronously, and the output shaft of the sling cylinder 413 extends, thereby driving the hanging rod 414 fixed on the output shaft of the sling cylinder 413 to move toward the packaging machine. After the hanging rod 414 moves to the limit distance, the hanging rod 414 contacts the ton bag, and the driving motor 401 runs in the reverse direction to drive the lifting plate 410 to gradually rise in the cam frame 402. During the rising process of the lifting plate 410, the hanging rod 414 is driven to move up along the surface of the ton bag. When the hanging rod 414 moves up, it hooks the sling of the ton bag and drives the sling to move upward to a specified height. After that, the driving motor 401 stops running, and the lifting plate 410 stops moving upward. Then start motor 220. When motor 220 is running, it drives the two moving blocks 411 to move in opposite directions. When the two moving blocks 411 move in opposite directions, they drive the two supporting plates 412 to move away from each other. When the two supporting plates 412 move away from each other, the two hanging rods 414 are driven to move away from each other through the hanging belt cylinder 413. After the two hanging rods 414 move to the set distance, motor 220 stops running. At this time, the slings of the ton bag hanging on the two hanging rods 414 are straightened, and then the hooks of the packaging machine move to hook the straightened slings. At this time, the driving motor 401 runs to drive the lifting plate 410 to move downward. During the movement, motor 220 runs in the opposite direction to make the two moving blocks 411 move closer to each other. At the same time, the output shaft of the hanging belt cylinder 413 contracts, driving the hanging rod 414 to return to its original position.

[0085] After the packaging machine has filled the ton bag with alumina powder, the controller controls the mobile motor 501 to run. When the mobile motor 501 runs, it drives the driving gear to rotate. Since the driving gear is meshed with the rack 511, the wing plate 513 drives the sliding plate 502 to move toward the packaging machine on the fixed frame 509 when the driving gear rotates. When the sliding plate 502 moves, it drives the long rod 518, the clamping cylinder 2 519 and the clamping rod 2 520 to move synchronously to the ton bag. When the clamping rod 2 520 moves to both sides of the ton bag, the controller starts the clamping cylinder 2 519. The clamping cylinder 2 519 drives the two clamping rods 2 520 to approach each other by extending the output shaft to clamp the bag mouth of the ton bag. At this time, the controller controls the driving motor 401 to run in the reverse direction, and synchronously starts the plate chain conveyor belt. When the driving motor 401 runs in the reverse direction, the clamping rod The second 520 clamps the mouth of the ton bag and moves it toward the original position. During the movement of the supporting rod, the plate chain conveyor belt drives the ton bag filled with alumina powder to move synchronously at the same speed. When the ton bag moves to the positioning sensor 510, the positioning sensor 510 transmits the monitoring signal to the controller. The controller controls the drive motor 401 and the plate chain conveyor belt to stop running, and controls all the moving cylinders to start synchronously. When the moving cylinders start, the output shafts push the limiting plates 515 facing each other to approach each other. When the limiting plates 515 approach each other, they drive the round rods and the movable round rods 522 to hold the mouth of the ton bag. The controller then controls the shrinking cylinder 521 to start. When the two shrinking cylinders 521 are running, they push the movable round rod 522 to move. When the movable round rod 522 moves, it drives the two shrinking clamps to approach each other to squeeze and tighten the mouth of the ton bag. At this time, the controller controls the push cylinder 516 to start. When the push cylinder 516 is running, the pusher moves toward the ton bag until the strapping opening of the tie machine 517 is inserted into the bag opening of the tightened ton bag, and then the tie machine 517 runs to tie the bag opening of the ton bag. After the strapping is completed, the controller reversely starts the push cylinder 516, and the push cylinder 516 drives the tie machine 517 to return to its original position. Then the controller controls the laser inkjet printer 508 to inkjet the ton bag, and then the controller controls the clamping cylinder 2 519, the shrinking cylinder 521 and the moving cylinder to run in reverse, release the clamping of the shrinking clamp, the clamping rod 2 520, the round rod and the movable round rod 522 on the ton bag, and finally start the plate chain conveyor again to transport the tied ton bag away. Repeating this process can continuously bundle and inkjet the ton bag.
