Description

Technical Field

[0001] This invention relates to the field of ton bag unloading technology, and in particular to a magnetic suction device for rapid unloading of ton bags. Background Technology

[0002] ton bags are generally used for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. They are typically square-shaped and have four small or two large hanging loops on the side. In practice, the loops are usually secured to the crane hook by hand, which is inefficient. Furthermore, unloading the ton bag requires manually opening the discharge port, posing a safety hazard. Discharge tools such as utility knives can easily fall into the hopper due to material impact, increasing the risk to product quality.

[0003] Chinese patent application CN202111168440.4 discloses a ton bag unpacking machine, which has a box on the frame and a receiving cavity inside the box; a bottom support is connected to the bottom of the box, and the inner cavity of the bottom support is connected to the receiving cavity of the box; an air extraction device is provided at the bottom of the receiving cavity; when in use, the air extraction device can suck up the ton bag for positioning.

[0004] However, in actual use, the inventors found that the method of manually fixing the ear ropes of the ton bags to the crane hook was time-consuming, labor-intensive, and inefficient. Furthermore, the ton bags needed to be manually untied during unloading, which not only posed a production safety hazard but also affected the unloading efficiency of the ton bags.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 1-18 As shown, a magnetic suction device for rapid unloading of ton bags is provided. The ton bag includes a bag body 6, two sets of hanging ear ropes 61 symmetrically arranged at the upper end of the bag body 6, a discharge cylinder 62 arranged at the lower end of the bag body 6, four sets of magnetic card frames 63 symmetrically arranged on the discharge cylinder 62, and elastic cable ties 64 inserted inside the four sets of magnetic card frames 63 for securing the discharge cylinder 62.

[0048] The magnetic suction device includes a conveying mechanism 1, a magnetizing mechanism 2 mounted on the conveying mechanism 1 for attaching magnetic clips 7 to the ear loops 61 of the ton bag, a magnetic lifting mechanism 3 mounted on the conveying mechanism 1 for lifting the ton bag, a clamping and shaking mechanism 4 mounted on the magnetic lifting mechanism 3 for clamping and shaking the ton bag, and a material control mechanism 5 mounted on the clamping and shaking mechanism 4 for controlling the opening of the discharge cylinder 62 of the ton bag.

[0049] It should be noted that the ton bags in this invention are customized according to the company's equipment needs and are used for material transfer between different workshops within the company. The ton bags can be reused, saving the company economic costs.

[0050] In this embodiment, the magnetic attachment mechanism 2, the magnetic lifting mechanism 3, and the material control mechanism 5 work together to achieve the following: First, the magnetic clip 7 can be detachably installed on the top of the hanging rope 61 of the ton bag, and the ton bag can be lifted and transported to the top of the silo using the magnetic attraction effect, thus achieving the effect of automated hoisting of the ton bag, saving manpower and time, improving production efficiency, and the ton bag and the magnetic clip 7 can be recycled, reducing the economic cost of the enterprise. Second, the discharge cylinder 62 of the ton bag can be opened automatically, which facilitates the unloading of the ton bag, avoids the safety hazards of manual operation, and improves the unloading efficiency of the ton bag.

[0051] In detail, ton bags filled with materials are placed in the space between two positioning plates 13 on the conveyor belt 12. As the conveyor belt 12 carries the ton bags forward, the straightening component 21 lifts and straightens the hanging loops 61 on both sides of the ton bag. The magnetic component 22 installs a magnetic block 7 on the top of the hanging loops 61. After the conveyor belt 12 carries the ton bags to a position below the transmission component 31, the chain 312 carries the magnetic suction component 32 and moves synchronously with the ton bags. At the same time, the magnetic suction component 32 magnetically attracts the top of the hanging loops 61 of the ton bags. Then, the straightening component 21 and the magnetic component 22 detach from the ton bags and reset. After the ton bags are removed from the support of the conveyor belt 12, the magnetic suction component 32 lifts... As the ton bag continues to move forward, the clamping component 41 clamps both sides of the ton bag to reduce the stress on the hanging rope 61. When the magnetic suction component 32 lifts the ton bag and moves it to the top of the hopper, the magnetic drive component 51, driven by the power component 52, opens the discharge cylinder 62 of the ton bag to unload the material. At the same time, the clamping component 41, driven by the shaking component 42, pulls and shakes the ton bag to speed up the unloading process and prevent the discharge cylinder 62 from becoming blocked. After the ton bag is unloaded, the clamping component 41 and the magnetic drive component 51 reset. The elastic cable tie 64, due to its own elasticity, re-secures the discharge cylinder 62. Finally, the magnetic suction component 32 drops the empty ton bag to reset. The empty ton bag and the magnetic card block 7 are collected and reused.

[0052] Furthermore, such as Figure 1-4As shown, the conveying mechanism 1 includes a conveying frame 11, two sets of conveyor belts 12 spaced apart and arranged side by side synchronously on the conveying frame 11, and several sets of positioning plates 13 arranged on the conveyor belts 12 for limiting the spacing of the ton bags.

[0053] It should be noted that there is a gap between the two sets of spaced conveyor belts 12, which is adapted to the discharge cylinder 62 of the ton bag. During the conveying process, the discharge cylinder 62 of the ton bag moves forward along the gap to ensure that the ton bag is placed stably on the conveyor belt 12.

[0054] In this embodiment, the ton bags can be stably placed on the conveyor belt 12 by the cooperation of the conveyor belt 12 and the positioning plate 13. The ton bags are spaced apart by the positioning plate 13, which makes it convenient for the clamping assembly 41 to clamp the two sides of the ton bags.

[0055] In detail, manual labor or existing mechanical equipment will place ton bags containing materials of the same size in sequence between two positioning plates 13 on the conveyor belt 12, and the conveyor belt 12 will carry the ton bags forward.

[0056] Furthermore, such as Figure 4-9 As shown, the magnetizing mechanism 2 includes several sets of straightening components 21 symmetrically arranged on the conveyor belt 12 for straightening the ear loops 61 of the ton bag upwards, and magnetizing components 22 arranged on the straightening components 21 for installing the magnetic card block 7 on the ear loops 61.

[0057] The straightening assembly 21 includes several sets of L-shaped support plates 211 arranged on the conveyor belt 12, U-shaped brackets 212 arranged on the L-shaped support plates 211, two sets of sliding holes respectively opened on the vertical part of the U-shaped brackets 212, lifting blocks 213 slidably arranged in the sliding holes, horizontal rods 214 penetrating and slidably arranged on the lifting blocks 213, scraper hooks 215 arranged near one end of the horizontal rods 214 near the ton bag and having a slope, a stop block arranged at one end of the horizontal rods 214 on the raw material ton bag, a first elastic element 216 arranged between the upper end of the sliding hole and the lifting block 213, a second elastic element arranged between the stop block and the lifting block 213, two sets of side plates 217 symmetrically arranged on the conveyor frame 11, a first limiting rail 218 arranged on the side plates 217 for driving the horizontal rods 214 to translate, and a second limiting rail 219 arranged on the side plates 217 for driving the horizontal rods 214 to rise and fall.

[0058] The magnetic assembly 22 includes a material discharge cylinder 221 disposed on the horizontal rod 214 and containing several sets of magnetic blocks 7, a material pushing channel 222 disposed on the horizontal rod 214 and adapted to the magnetic blocks 7, a first hydraulic component 223 disposed at one end of the material pushing channel 222, and an L-shaped push plate 224 disposed at the output end of the first hydraulic component 223. The distance from the lower port of the material discharge cylinder 221 to the bottom of the material pushing channel 222 is equal to the height of the magnetic blocks 7.

[0059] It should be noted that the upper end of the discharge cylinder 221 is provided with an end cap to prevent the magnetic block 7 inside the discharge cylinder 221 from falling off the upper end of the discharge cylinder 221 when the magnetic assembly 22 moves with the conveyor belt 12 to the position above the conveyor frame 11.

[0060] It is worth mentioning that the magnetic card block 7 is a loop-shaped structure with one side open, which can hold the top of the hanging rope 61 of the ton bag.

[0061] It is worth mentioning that during the process of straightening the ear loop 61 by the horizontal bar 214, the sloping scraper hook 215 can guide the ear loop 61 to the end of the horizontal bar 214. After the top of the ear loop 61 rises and detaches from the bag body 6 of the ton bag, the scraper hook 215 prevents the ear loop 61 from slipping off the end of the horizontal bar 214, and can limit the magnetic clip 7 clamped on the top of the ear loop 61 to prevent the magnetic clip 7 from falling off.

[0062] In this embodiment, the straightening component 21 and the magnetic mounting component 22 work together to automatically lift and straighten the hanging ear ropes 61 dangling on both sides of the ton bag, facilitating the lifting of the ton bag, and positioning the top of the hanging ear ropes 61 to facilitate the installation of the magnetic clip 7. On the other hand, they can automatically clamp a magnetic clip 7 onto the top of the hanging ear rope 61 with high precision, limiting the installation of the magnetic clip 7 and preventing it from falling off the hanging ear rope 61.

[0063] In detail, after the conveyor belt 12 carries the ton bag forward to the position of the first limiting rail 218, the horizontal bar 214, driven by the first limiting rail 218, abuts against the side of the ton bag. Then, driven by the second limiting rail 219, the horizontal bar 214 rises along the side wall of the ton bag. During the rising process, the scraper hook 215 with a slope can guide the ear rope 61 to the end of the horizontal bar 214. After the horizontal bar 214, with the top of the ear rope 61, rises to a specified height, the first hydraulic component 223 drives the L-shaped push plate 224 to push a magnetic block 7 along the pushing channel 222 to the position of the scraper hook 215, so that the magnetic block 7 is clamped on the top of the ear rope 61. After the magnetic lifting mechanism 3 attracts the magnetic block 7 on the ear rope 61, the first hydraulic component 223 drives the L-shaped push plate 224 to reset, and the horizontal bar 214 resets, ready for the next use.

[0064] Furthermore, such as Figure 10-11 As shown, the magnetic lifting mechanism 3 includes a transmission component 31 disposed above the conveyor frame 11 and synchronously disposed with the conveyor belt 12, and several sets of magnetic suction components 32 disposed on the transmission component 31 and moving synchronously with the ton bag;

[0065] The transmission assembly 31 includes a transmission frame 311 disposed on the transmission frame 11 and a chain 312 disposed on the transmission frame 311 and synchronously disposed with the conveyor belt 12;

[0066] The magnetic attraction assembly 32 includes several sets of second hydraulic components 321 disposed on the chain 312, a lifting plate 322 disposed at the output end of the second hydraulic components 321, two sets of first electromagnets 323 symmetrically disposed at the bottom of the lifting plate 322, two sets of L-shaped baffles 324 that pass through and slide on the lifting plate 322 and are used to block the opening of the magnetic card block 7, and a third elastic component 325 disposed between the L-shaped baffles 324 and the lifting plate 322.

[0067] In this embodiment, the transmission component 31 and the magnetic suction component 32 work together to automatically lift the ton bags one by one and transfer them to the top of the hopper for unloading.

[0068] In detail, after the conveyor belt 12 carries the ton bag to a position below the transmission component 31, the second hydraulic component 321 lowers the lifting plate 322 in sequence, so that the first electromagnet 323 contacts the magnetic locking block 7 at the top of the ton bag's hanging ear rope 61. The L-shaped baffle 324 rises relative to the horizontal bar 214 under the force of the scraper hook 215 at the end of the horizontal bar 214. After the first electromagnet 323 is charged and magnetized, it attracts the magnetic locking block 7 at the top of the hanging ear rope 61. Then, the second hydraulic component 321 raises the lifting plate 322, thereby lifting the ton bag through the hanging ear rope 61. When lifting the ton bag, the L-shaped baffle 324 is reset under the drive of the third elastic component 325, thereby blocking the opening of the magnetic locking block 7 to prevent the hanging ear rope 61 from falling off the magnetic locking block 7, thus improving the stability of lifting the ton bag. Finally, the chain 312 transfers the lifted ton bag to the top of the hopper for unloading.

[0069] Furthermore, such as Figure 10-15 As shown, the clamping and swaying mechanism 4 includes a clamping component 41 that is lifted and lowered on the magnetic suction component 32 and a swaying component 42 that is disposed on the clamping component 41;

[0070] The clamping assembly 41 includes two sets of vertical plates 411 respectively disposed at both ends of the lifting plate 322, lifting holes formed on the vertical plates 411, a lead screw 412 rotatably disposed between the two ends of the lifting holes, a slider threaded through the lead screw 412 and adapted to the lifting holes, a support rod 413 horizontally disposed on the slider and having a limit block at its end, a hanger 414 slidably disposed on the support rod 413, a fourth elastic element disposed between the hanger 414 and the limit block, several sets of insertion rods 415 penetrating and slidably disposed on the side of the hanger 414, and one end of the insertion rod 415 disposed near the ton bag. The components include a clamping frame 416, a fifth elastic member disposed between the clamping frame 416 and the side of the hanger 414, two sets of arc-shaped elastic clamping plates 417 symmetrically disposed on the inner sidewall of the clamping frame 416, several sets of elastic telescopic members disposed between the arc-shaped elastic clamping plates 417 and the inner sidewall of the clamping frame 416, an extension rod disposed on the hanger 414, two sets of hanging plates 418 symmetrically disposed on the transfer frame 311, a third limiting rail 419 disposed on the hanging plate 418 and used to drive the extension rod to move the clamping frame 416 toward the ton bag, and a first stepper motor disposed on the top of the vertical plate 411 and used to drive the lead screw 412.

[0071] It is worth mentioning that the fifth elastic element is used to drive the clamping frame 416 to reset. After the clamping frame 416 is released from the ton bag, the gear 423 of the shaking assembly 42 disengages from the rack 424, causing the clamping frame 416 to lose its power source. The clamping frame 416 is reset under the drive of the fifth elastic element and keeps the clamping frame 416 in a symmetrical open state for easy use next time.

[0072] It should be noted that the elastic telescopic component is composed of a telescopic rod and a spring, which enables the clamping frame 416 to elastically clamp the two side walls of the ton bag through the arc-shaped elastic clamping plate 417.

[0073] The swaying assembly 42 includes a shaft 421 vertically mounted on the hanger 414, several sets of eccentric wheels 422 mounted on the shaft 421 at different eccentric positions, a gear 423 mounted on the shaft 421, and a rack 424 mounted on the hanging plate 418 via a connecting rod for driving the gear 423. One end of the insertion rod 415, which is away from the ton bag, slides and matches the circumference of the eccentric wheel 422 via a hinge block.

[0074] It should be noted that the two gears 423 located on both sides of the ton bag rotate in opposite directions under the drive of the rack 424, so that the two upper eccentric wheels 422 drive the two upper clamping frames 416 to move to the right at the same time, and the two lower eccentric wheels 422 drive the two lower clamping frames 416 to move to the left at the same time. This cycle repeats to shake the ton bag and cause the material inside the ton bag to flow, thereby speeding up the unloading of the ton bag.

[0075] In this embodiment, the clamping component 41 and the shaking component 42 work together to, on the one hand, assist in clamping the outer wall of the ton bag during the hoisting process, preventing the ton bag from falling off the hook, reducing the stress on the hanging rope 61, and improving the service life of the hanging rope 61; on the other hand, the ton bag can be repeatedly shaken during the unloading process, so that the material inside the ton bag can be discharged quickly, accelerating the unloading speed of the ton bag, while increasing the fluidity of the material inside the ton bag and preventing the discharge cylinder 62 of the ton bag from becoming blocked.

[0076] In detail, after the magnetic suction assembly 32 lifts the ton bag away from the conveying mechanism 1, the first stepper motor drives the lead screw 412 to rotate. The lead screw 412 drives the support rod 413 to lower the hanger 414 to the designated height. When passing the third limit track 419, the third limit track 419 drives the hanger 414 to move the clamping frame 416 toward the ton bag, so that the clamping frame 416 clamps the outer wall of the ton bag from both sides through the arc-shaped elastic clamping plate 417. During the unloading process of the ton bag, the rack 424 drives the two gears 423 to rotate in opposite directions, so that the two upper eccentric wheels 422 drive the two upper clamping frames 416 to move to the right at the same time, and the two lower eccentric wheels 422 drive the two lower clamping frames 416 to move to the left at the same time. This cycle repeats to shake the ton bag and make the material inside the ton bag flow, thus speeding up the unloading of the ton bag.

[0077] Furthermore, such as Figure 16-18 As shown, the material control mechanism 5 includes a magnetic drive assembly 51 disposed on the shaking assembly 42 and used to respectively attract the magnetic card frame 63 on the discharge cylinder 62, and a power assembly 52 disposed on the shaking assembly 42 and used to drive the magnetic drive assembly 51 to work.

[0078] The magnetic drive assembly 51 includes two sets of fixed disks 511 symmetrically arranged at the bottom of the hanger 414, two sets of limiting grooves 512 formed at the bottom of the fixed disks 511, a movable block 513 slidably matched in the limiting groove 512, a control rod 514 disposed on the movable block 513 with its end penetrating the periphery of the fixed disk 511, a second electromagnet 515 disposed at the end of the control rod 514 and magnetically matched with the magnetic card frame 63, and a lever 516 disposed on the movable block 513.

[0079] It should be noted that two of the control rods 514 are straight rods used to drive the magnetic clip frames 63 on the left and right sides of the ton bag discharge cylinder 62, while the other two control rods 514 are bent rods used to drive the front and rear magnetic clip frames 63 of the ton bag discharge cylinder 62, thereby opening the ton bag discharge cylinder 62.

[0080] The power assembly 52 includes a power disk 521 coaxially rotatably disposed below the fixed disk 511, two sets of arc-shaped limiting holes 522 formed on the power disk 521 for simultaneously driving the lever 516, and a second stepper motor 523 disposed on the hanger 414 for driving the power disk 521.

[0081] In this embodiment, the magnetic drive assembly 51 and the power assembly 52 work together to automatically open the discharge cylinder 62 of the ton bag, which facilitates the unloading of the ton bag and reduces safety hazards to workers.

[0082] In detail, after the chain 312 transfers the hoisted ton bag to above the hopper, when the clamping frame 416 holds both sides of the ton bag, each of the second electromagnets 515 of the magnetic drive assembly 51 comes into contact with the magnetic card frame 63. The second electromagnets 515 are charged and magnetized, attracting the magnetic card frame 63. Then, the second stepper motor 523 drives the power disk 521 to rotate. The power disk 521 drives the lever 516 to move the control lever 514 outward through the arc-shaped limiting hole 522, so that the lever 516 passes through the second electromagnet. Iron 515 moves outward along with each magnetic card frame 63, forcing the elastic cable tie 64 to expand outward, thereby opening the discharge cylinder 62 and the ton bag begins to unload. After unloading is completed, the second electromagnet 515 is de-energized and loses its magnetism, the elastic cable tie 64 resets and re-tightens the discharge cylinder 62, the power disc 521 drives the second electromagnet 515 to reset, the clamping assembly 41 and the shaking assembly 42 reset, the first electromagnet 323 is de-energized and loses its magnetism, and rises to reset. Finally, the ton bag and magnetic card block 7 fall off and are collected for reuse.

[0083] Example 2

[0084] like Figure 2 and Figure 10 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0085] Furthermore, such as Figure 2 and Figure 10 As shown, a recycling bin 8 is provided on the transmission frame 311. The recycling bin 8 is used to collect empty ton bags after unloading and magnetic clips 7 on the ear loops 61.

[0086] In this embodiment, after unloading is completed via the recycling bin 8, the magnetic lifting mechanism 3 releases the empty ton bag and magnetic card block 7, which fall into the recycling bin 8 for reuse, thus saving economic costs.

[0087] Work process:

[0088] The ton bags filled with materials are placed in the space between two positioning plates 13 on the conveyor belt 12. As the conveyor belt 12 moves forward carrying the ton bags, the straightening component 21 lifts and straightens the hanging loops 61 on both sides of the ton bag. The magnetic component 22 installs a magnetic block 7 on the top of the hanging loops 61. After the conveyor belt 12 moves to a position below the transmission component 31 carrying the ton bags, the chain 312 carries the magnetic suction component 32 and moves synchronously with the ton bags. At the same time, the magnetic suction component 32 magnetically attracts the top of the hanging loops 61 of the ton bags. Then, the straightening component 21 and the magnetic component 22 detach from the ton bags and reset. After the ton bags are removed from the support of the conveyor belt 12, the magnetic suction component 32 lifts the ton bags and continues... As the bag continues to move forward, the clamping component 41 clamps both sides of the ton bag, reducing the stress on the hanging rope 61. When the magnetic suction component 32 lifts the ton bag and moves it to the top of the hopper, the magnetic drive component 51, driven by the power component 52, opens the discharge cylinder 62 of the ton bag to unload the material. At the same time, the clamping component 41, driven by the shaking component 42, pulls and shakes the ton bag to speed up the unloading process and prevent the discharge cylinder 62 from becoming blocked. After the ton bag is unloaded, the clamping component 41 and the magnetic drive component 51 reset. The elastic cable tie 64, due to its own elasticity, re-secures the discharge cylinder 62. Finally, the magnetic suction component 32 releases the empty ton bag to reset. The empty ton bag and the magnetic card block 7 fall into the recycling bin 8 for reuse.
