Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ton bag packaging, in particular to a ton bag automatic packaging production line. BACKGROUND

[0002] Alumina is an inorganic compound widely used in multiple industries, which has a white amorphous powder or crystalline appearance and a delicate texture. As a material widely used in multiple industries, the choice of packaging method for alumina powder is crucial for ensuring product quality, transportation safety, and operational convenience. Ton bags can hold from a few hundred kilograms to more than a ton of material, making them ideal for large-scale alumina powder transportation and storage. Compared to small packaging, ton bags can more effectively utilize warehouse or transportation space, reducing unit costs. However, when alumina powder is packaged in ton bags now, workers manually place the ton bag over the discharge pipe of the packaging machine. The clamping mechanism of the packaging machine clamps and fixes the ton bag opening, and finally the packaging machine fills the ton bag with alumina powder. However, this manual operation of placing the bag on the packaging machine is inefficient and poses a certain safety risk. Therefore, to improve the efficiency of alumina powder packaging and reduce safety risks, the present application designs an automatic production line for ton bag packaging. SUMMARY

[0080] The specific implementation process is as follows:

[0081] The feeding bin 1 is used, the ton bag is stacked on the two supporting plates 105 by manual, at this time, the one feeding cylinder 103 is started by the controller, the output shaft of the feeding cylinder 103 starts to stretch, the supporting plate 105 is moved on the slide rail when the output shaft of the feeding cylinder 103 stretches, when the supporting plate 105 moves to the specified position, the baffle 109 is just located at the position sensor 107, the signal is transmitted to the controller after the position sensor 107 detects the baffle 109, at this time, the controller controls the feeding cylinder 103 to stop running, the supporting plate 105 keeps stable, after the ton bag on the supporting plate 105 is used up, the infrared sensor monitors that there is no ton bag on the supporting plate 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 supporting plate 105 to contract, the supporting plate 105 is moved to the original position when the output shaft of the feeding cylinder 103 contracts, the position sensor 107 on the position monitors the baffle 109 on the supporting plate 105 and transmits the monitoring signal to the controller, at this time, the controller controls the feeding cylinder 103 to stop running, then the worker can supplement the ton bag on the supporting plate 105. At the same time when the supporting plate 105 returns to the original position, the controller controls the output shaft of the other feeding cylinder 103 to stretch, the other supporting plate 105 is moved to the specified position by the output shaft of the feeding cylinder 103 to supplement the ton bag, to avoid the ton bag shortage. The two supporting plates 105 are alternately supplied.

[0082] When the bag supporting device 2 is in use, the suction cup 302 on the mechanical arm 309 sucks up the ton bag and exposes the bag opening, and then the controller controls the motor two 220 to start running. When the motor two 220 runs, it drives the driving gear one above the support plate 206 to rotate. When the driving gear one rotates, it drives the annular chain two 218 to move. When the annular chain two 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 two 220 to stop running, and then starts the motor one 219. When the motor one 219 runs, it drives the transmission gear to rotate. When the transmission gear one 208 rotates, it drives the chain 407 one to move. When the chain 407 one moves, it drives the moving plate 204 to move towards the bag opening of the ton bag. Since the support plate 206 is fixedly connected to the moving plate 204, the support plate 206 is fixedly connected to the circular plate 212 through the connecting plate 211. The circular plate 212 is rotatably connected to four support rods 213 evenly spaced on the circumference of the circular plate 212. Therefore, when the moving plate 204 moves, it synchronously drives the support rods 213 to move, 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 one 219, and then starts the bag supporting cylinder to make the output shaft of the bag supporting cylinder elongate. When the output shaft of the bag supporting cylinder elongates, it pushes the linkage plate 214 to move towards the elongation direction of the output shaft of the bag supporting cylinder. When the linkage plate 214 moves, the four linkage rods 215 gradually change from the inclined state to the state perpendicular to the support rods 213. At this time, the four support rods 213 are lifted by the linkage rods 215, so that the spacing between the support rods 213 increases. As the spacing between the support rods 213 increases, the support rods 213 open the bag opening of the ton bag, so that the bag opening assumes a rectangular shape, facilitating the clamping of the ton bag by the mechanical arm 309 in the next process. After the ton bag is clamped by the mechanical arm 309, the controller controls the output shaft of the bag supporting cylinder to shorten. When the output shaft of the bag supporting cylinder shortens, it drives the linkage plate 214 to return to the original position. In the process of returning to the original position, the linkage plate 214 pulls the linkage rods 215. Then, the linkage rods 215 gradually change from the perpendicular state to the inclined state of the support rods 213. In this process, the linkage rods 215 pull the support rods 213 to move towards the center. At this time, the support rods 213 are separated from the bag opening of the ton bag. Then the controller controls the motor one 219 to start in reverse. When the motor one 219 runs in reverse, it drives the moving plate 204 to move backwards on the rectangular frame 202 to return to the original position, thereby driving the support rods 213 to be taken out of the bag opening of the ton bag. In the process of vertically moving the base plate 210 on the support plate 206, the two limit sensors 205 monitor the position of the base plate 210. When the base plate 210 moves to the position of the limit sensor 205, the limit sensor 205 transmits a monitoring signal to the controller, and the controller stops the movement of the base plate 210 by stopping the operation of the motor.

[0083] When the mechanical arm hand claw 3 operates, the visual sensor 308 first shoots and locates the ton bag on the supporting plate 105 of the feeding bin 1, and then transmits the signal to the controller. At this time, the controller controls the mechanical arm 309 to drive the connecting piece 301 to move to the top of the ton bag. Then the controller drives the connecting piece 301 to move downward through the mechanical 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 to generate negative pressure in the suction cup 302 to suck the bag opening of the ton bag. After the ton bag is sucked by the suction cup 302, the connecting piece 301 is moved upward by the mechanical arm 309. At this time, the part of the bag opening of the ton bag sucked is pulled upward, and the part not sucked naturally falls downward under the action of gravity to make the bag opening face the bag supporting device 2. After the supporting rod 213 of the bag supporting device 2 is inserted into the bag opening of the ton bag and the bag opening is opened to make the bag opening rectangular, the air pump stops operating so that the suction cup 302 no longer generates negative pressure. The connecting piece 301 is rotated by the mechanical arm 309 so that the two clamping rods 304 are in the same vertical plane. The controller controls the output shaft of the clamping cylinder 306 to elongate so that a gap with a certain distance is formed between the clamping plate 305 and the clamping plate 307. The mechanical arm 309 operates to drive the two clamping plates 305 to move through the connecting piece 301 and the clamping rod 304. The gap between the two clamping plates 305 and the two clamping plates 307 is inserted into the upper edge and the lower edge of the bag opening supported and opened in a rectangular shape. 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, the clamping plate 307 moves 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 supporting rod 213 of the bag supporting device 2 exits from the bag opening of the ton bag. The controller controls the mechanical arm 309 to drive the connecting piece 301 to move to sleeve the bag opening of the ton bag on the discharge pipe of the packaging machine.

[0084] When the sling of the ton bag needs to be hung on the hook of the packaging machine, the driving motor 401 of the two sling assembly is started, and when the driving motor 401 operates, the lifting plate 410 is lowered to the bottom of the U-shaped frame 402, and then the four sling cylinders 413 are synchronously started, the output shaft of the sling cylinder 413 is elongated to drive the hanging rod 414 fixed on the output shaft of the sling cylinder 413 to move towards the packaging machine, after the hanging rod 414 moves to the limit distance, the hanging rod 414 contacts the ton bag, the driving motor 401 reverses to drive the lifting plate 410 to gradually rise in the U-shaped frame 402, and the lifting plate 410 drives the hanging rod 414 to move upwards along the surface of the ton bag during the rising process, the hanging rod 414 hooks the sling of the ton bag and drives the sling to move upwards to the specified height, and then the driving motor 401 stops operating, and at this time the lifting plate 410 stops moving upwards. Then start the motor two 220, when the motor two 220 operates, drive the two moving blocks 411 to move in opposite directions, when the two moving blocks 411 move in opposite directions, drive the two supporting plates 412 to move away from each other, when the two supporting plates 412 move away from each other, drive the two hanging rods 414 to move away from each other through the sling cylinder 413, after the two hanging rods 414 move to the set distance, the motor two 220 stops operating, at this time the sling of the ton bag hung on the two hanging rods 414 is straightened, then the hook of the packaging machine moves to hook the straightened sling, at this time the driving motor 401 operates to drive the lifting plate 410 to move downwards, during the moving process, the motor two 220 reverses to drive the two moving blocks 411 to move close to each other, and at the same time the output shaft of the sling cylinder 413 is contracted to drive the hanging rod 414 to return to the original position.

[0085] After the ton bag is filled with the aluminum powder by the packaging machine, the controller controls the movement motor 501 to operate. When the movement motor 501 operates, the driving gear is driven to rotate. Since the driving gear is engaged with the rack 511, the sliding plate 502 is driven by the wing plate 513 to move on the fixed frame 509 towards the packaging machine when the driving gear rotates. The sliding plate 502 drives the long rod 518, the clamping cylinder two 519 and the clamping rod two 520 to move synchronously to the ton bag when the sliding plate 502 moves. When the clamping rod two 520 moves to the two sides of the ton bag, the controller starts the clamping cylinder two 519 to start. The clamping cylinder two 519 drives the two clamping rods two 520 to approach each other to clamp the bag opening of the ton bag through the elongated output shaft. At this time, the controller controls the driving motor 401 to operate in reverse, and simultaneously starts the plate chain conveyor belt. When the driving motor 401 operates in reverse, the clamping rod two 520 clamps the bag opening of the ton bag to move towards the original position. In the process of moving the clamping rod, the plate chain conveyor belt drives the ton bag filled with the aluminum powder to move synchronously at the same speed. When the ton bag moves to the positioning sensor 510, the positioning sensor 510 transmits a monitoring signal to the controller. The controller controls the driving motor 401 and the plate chain conveyor belt to stop operating, and controls all movement cylinders to start synchronously. When the movement cylinders start, the output shaft pushes the limiting plates 515 facing each other to approach each other. The limiting plates 515 drive the round rod and the movable round rod 522 to hold the bag opening of the ton bag when the limiting plates 515 approach each other. The controller controls the necking cylinder 521 to start. When the two necking cylinders 521 operate, the movable round rod 522 is pushed to move. The movable round rod 522 drives the two necking clamps to approach each other to squeeze and tighten the bag opening of the ton bag when the movable round rod 522 moves. At this time, the controller controls the pushing cylinder 516 to start. When the pushing cylinder 516 operates, the machine moves towards the ton bag until the bundling opening of the bundling machine 517 is inserted into the bag opening of the ton bag which is tightened. Then the bundling machine 517 operates to bundle the bag opening of the ton bag. After the bundling is completed, the controller reversely starts the pushing cylinder 516 to drive the bundling machine 517 to return to the original position. Then the controller controls the laser code spraying machine 508 to spray the ton bag. Then the controller controls the clamping cylinder two 519, the necking cylinder 521 and the movement cylinders to operate in reverse to release the ton bag from the clamping of the necking clamp, the clamping rod two 520, the round rod and the movable round rod 522. Finally, the plate chain conveyor belt is started again to carry away the bundled ton bag. Thus, the ton bag can be continuously bundled and sprayed by repeating the above process.
