Description

Technical Field

[0001] The utility model relates to the technical field of heavy forklifts, in particular to an intelligent ton bag sling. Background Art

[0002] Ton bags, also known as bulk bags, are flexible transport packaging containers. They are also known as flexible bulk bags, bulk bags, and space bags. They are medium-sized bulk containers that can be transported in a unitized manner using a crane or forklift. They are convenient for transporting large quantities of bulk powdery materials and feature large capacity, light weight, and ease of loading and unloading. During port crane hoisting operations, many solid chemical products are packaged in ton bags, which are generally made of polyester fibers such as polypropylene and polyethylene. Once filled, a ton bag is usually lifted using a forklift. During the lifting process, the sling rope's lifting point (the intersection point of the two rope sections) above the ton bag is hung on the forklift's forks, and then the forklift is used to carry the bag. In the current production process, ton bags are mostly transported by forklifts, which has the following problems: 1) Ton bags squeeze and interfere with each other, and manual labor is required to arrange the lifting points and cooperate with the forklift operator to hang the lifting points on the fork of the forklift. The unhooking of ton bags is usually done manually, which is time-consuming and labor-intensive, resulting in low work efficiency; 2) There are crooked pulling and slanting during transportation, which can easily break the straps of the ton bags, reducing the service life of the ton bags. It is also not easy to arrange the ton bags neatly when loading; 3) Due to the large weight of ton bags, the ton bag ropes and forklift forks may slip, resulting in unstable driving and easy collision. It may not only damage the supporting equipment and cause equipment loss, but also affect the safety of the operators and bring greater risks to personal safety. With the rise and popularization of automatic spreaders and material detection methods, there is an urgent need for a highly integrated intelligent spreader to meet the requirements of automated lifting of ton bags.

[0057] The substantial technical effects and implementation process of this technical solution, i.e., the basic functions, are as follows:

[0058] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the utility model discloses an intelligent ton bag sling, which is mainly composed of a sling body 3, a hook system 1, a safety protection system, a lifting detection system, and a magnetic locking system 2;

[0059] The hook system includes a hanging beam 15, a left hook 12, a right hook 13, a locking plate 14 and a rotating shaft 11. The hanging beam 15 is mainly used as a load-bearing component and is installed in the middle position of the main beam frame 32 by bolts. The left hook 12 is located on the left side below the hanging beam 15. A shaft that drives the hook to rotate is provided on the left hook 12. The shaft is driven by a cylinder 17. The bottom of the cylinder 17 is installed on the hanging beam 15. The right hook 13 consists of a hook body and an engaging plate. It is located on the right side below the hanging beam 15. The locking plate 14 is located below the middle of the hanging beam 15, in which a mechanism for rotating the clamping plate is provided, which is driven by a cylinder 16. The cylinder 16 is placed above the hanging beam 15. The rotating shaft 11 passes through the left hook 12 and the right hook 13 and is connected to the gear 18. There are two rotating shafts 11. The front end of the rotating shaft 11 is connected to the left hook 12 and the right hook 13 respectively, and the rear end of the rotating shaft 11 is connected to a pair of mutually meshing gears 18 to ensure that when the rotating shaft 11 rotates, the left hook 12 and the right hook 13 move synchronously;

[0060] The magnetic locking system includes a left-side magnetic locking system and a right-side magnetic locking system. The left-side magnetic locking system and the right-side magnetic locking system have the same structure and are symmetrical in position. The magnetic locking system consists of a support plate 22, a magnetic bar 21, a magnetic bar slider 24, a front and rear sliding cylinder 23 and a left and right sliding cylinder 25. The magnetic locking system is located in the middle position of the main beam 32. The magnetic bar 21 is fastened to the bottom of the support plate 22 through a connecting piece. A magnetic bar slider 24 is installed on the magnetic bar 21. The other side of the magnetic bar slider 24 is connected to the front and rear sliding cylinder 23. The two sides of the support plate 22 are connected to the linear guide magnetic bar sliders, and the magnetic bar sliders are connected to the left and right sliding cylinders 25. The front and rear sliding cylinders 23 and the left and right sliding cylinders 25 work together to drive the magnetic bar slider 24 on the magnetic bar 21 to perform translational movement in the front, back, left and right directions. When handling ton bags, the following steps are included: 1) Adjusting the spacing between the intelligent ton bag spreader clamping frame 31 to be the same as the spacing between the forklift forks 4, starting the forklift to insert the forks 4 into the spreader clamping frame 31, and tightening the locking bolts on the clamping frame; 2) Operating the forklift to move the spreader above the ton bag lifting rope to be moved, driving the left and right magnetic locking systems of the magnetic locking system 2 to move to both sides of the ton bag. 3) Driving the left hook 12 to rise at a low speed to the limit position. As the left hook 12 moves upward, it contacts the bottom of the lifting beam 15, triggering the in-place sensor. The in-place sensor sends back a signal and stops the hook from rising. The left hook 12 and the right hook 13 are raised to their limit positions. 4) The forklift controls the intelligent ton bag sling to slowly descend until the magnetic bar 21 contacts the ton bag rope, and drives the left magnetic locking system and the right magnetic locking system in the magnetic locking system 2 to move directly below the hook. During the movement, the magnetic bar 21 in the magnetic locking system 2 adsorbs and locks the iron patch attached to the ton bag rope onto the magnetic bar 21. The magnetic bar 21 drives the ton bag rope to move directly below the hook to trigger the photoelectric sensor, and controls the pneumatic guide rail lock to tighten when the movement stops. 5) The forklift controls the intelligent ton bag sling to slowly rise and pull up the rope. The left and right sliding cylinders 25 drive the magnetic bar sliders 24 on the magnetic bar 21 to move from the edge positions on both sides to the middle. The magnetic bar sliders 24 push the ropes adsorbed on the magnetic bar 21 to gather directly below the hook. After the magnetic bar sliders 24 are in place, all the ropes are gathered directly below the hook. 6) Drive the left hook 12 to descend at a low speed and pass under the lifting rope adsorbed on the magnetic bar 21. The left hook 12 and the right hook 13 are linked by a pair of meshing gears 18. When the left hook 12 descends to the lowest point, the right hook 13 also descends to the lowest point and engages with the left hook 12. At this time, the lifting rope is inside the hooks on both sides. 7) The spreader PLC superimposes the material passing signal, clamping signal, and load signal to comprehensively determine that the ton bag is firmly grasped, and then the weight is verified by the weighing sensor. After receiving the signal, the locking plate 14 drives the cylinder 16 to rotate the lock hook piece, locking the rotating shaft 11 so that it does not rotate. After the above conditions are met, the forklift fork 4 begins to rise and the lifting is carried out.8) The intelligent bulk bag lifter moves the bulk bag to its destination and executes a blanking motion, the opposite of the clamping motion. It first controls the left and right magnetic locking systems of magnetic locking system 2 to move to the sides of the bulk bag. It then controls the left hook 12 to rise, opening locking plate 14 to disengage the left and right hooks 12 and 13 from the bulk bag. The forklift is then controlled to raise the intelligent bulk bag lifter and disengage the bulk bag's lifting rope, completing the lift cycle. 9) Repeat steps 1) through 8) to proceed to the next lift cycle.
