Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to a ton bag conveyor mostly used for chemical products. Background Art

[0002] With the acceleration of industrialization and automation, efficient logistics and material handling have become key factors in improving productivity and reducing costs for businesses. Traditional manual handling and short-distance conveying equipment are no longer able to meet the needs of large-scale, long-distance, and highly efficient material handling. Therefore, the ton bag conveyor has emerged as an indispensable logistics equipment in modern industrial production.

[0003] After searching, the existing announcement number CN118811375B discloses that during the use of a long-distance integral lifting ton bag conveyor, the conveyor belt will expand and contract due to changes in ambient temperature. After long-term use, the conveyor belt will gradually wear or age. In addition, during the use of the ton bag conveyor, the load distribution on the conveyor is prone to unevenness due to human operation and other reasons, which will cause the local tension of the conveyor belt to be too high. It includes a frame, and a propulsion mechanism is provided at one end of the inner side of the frame. The propulsion mechanism includes a first transmission shaft, which is rotatably connected to the frame, and a first rotary wheel is fixedly connected to the end of the first transmission shaft away from the frame. When the tension of the conveyor belt is reduced or excessive, the tension of the conveyor belt is adjusted by the propulsion mechanism. After the adjustment is completed, the propulsion mechanism is locked by the locking mechanism to prevent the tension of the adjusted conveyor belt from increasing or decreasing again.

[0004] Existing ton bag conveyors also have the following defects: (1) Ton bags are generally made of soft materials and are loaded with powder or granular items. After being filled, the gaps are small and elastic, and they are prone to "swelling" or local bulges / offsets during transportation. Generally, manual assistance is required to straighten them, otherwise they are prone to shifting or damage during transportation; (2) After the ton bag is placed on the material tray, it cannot automatically adapt to ton bags of different sizes according to its own gravity. When fixing ton bags of different sizes or weights, manual intervention is required, and the work efficiency is low. Summary of the Invention

[0005] The purpose of the present invention is to provide a ton bag conveyor which is mostly used for chemical products, aiming to solve the problems existing in the existing ton bag conveyors.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a ton bag conveyor for chemical products, comprising a circulating conveying module, the circulating conveying module comprising a circulating conveying platform, a conveyor belt, and a limiting guide rail, the limiting guide rail being fixedly arranged on the surface of the circulating conveying platform, and further comprising: The tray module includes a base, a support, an adaptive clamping part, a deviation correcting part and a transmission part. The conveyor belt is fixedly connected to one end of the base. The base is slidably arranged between the circulating conveying platform and the limiting guide rail.

[0027] Please refer to Figure 4 and Figure 12Furthermore, the base 21 also includes a connecting member 211, a bracket 213, an infrared lens 215, a limit frame 217 and an electromagnet 216.

[0028] See also Figures 5 to 9 Furthermore, the support member 22 includes a tray 221, a limiting rod 222, a first spring 223 and a ball head rod 224.

[0030] In an embodiment of the present invention, when the gravity of the ton bag presses down the support member 22, the ball head rod 224 slides along the curved guide rail 2323, forcibly converting the vertical linear motion into the rotational motion of the center sleeve 2322. The rotation of the center sleeve 2322 drives the rotating disk 2321 on its surface to rotate, and the arc-shaped hole 2324 on the rotating disk 2321 intersects with the radial hole 212 on the base 21, forcing the radial moving member 231 to slide radially toward the ton bag in the cross hole. Based on this design, the ton bag's own gravity can be directly used to drive the clamping mechanism to move without external power. The heavier the ton bag, the more the support member 22 descends, the larger the rotation angle of the rotating disk 2321, and the larger the radial displacement of the radial moving member 231. The clamping range is automatically adjusted, and the correction part 24 fixed on the radial moving member 231 moves synchronously radially to achieve the initial wrapping limit of the ton bag from the longitude and latitude directions (i.e., the longitudinal and transverse directions of the bag body).

[0031] See also Figure 14In one embodiment of the present invention, the transmission part 25 includes a transmission gear ring 251, a transmission tube 252, a second transmission gear 253, a pin 254, a second spring 255 and a third transmission gear 256.

The transmission gear ring 251 is rotatably set between several brackets 213.

[0032] See also Figure 6 and Figure 9 Furthermore, the radial moving member 231 includes a movable pin body 2311, a limiting structure 2312 and a ratchet 2313. The limiting structure 2312 is fixedly arranged on the surface of the movable pin body 2311. The movable pin body 2311 is slidably arranged in the radial hole 212 and the arc hole 2324. The limiting structure 2312 is an arc-shaped shell, and the ratchet 2313 is arranged in the arc-shaped shell.

[0033] See also Figure 13 Furthermore, the correction part 24 also includes a protrusion 245 and an arc-shaped gear rod 246, and the protrusion 245 and the arc-shaped gear rod 246 are fixedly arranged on the surface of the rotating shaft 243. The protrusion 245 can contact the arc-shaped shell, and the arc-shaped gear rod 246 is engaged with the ratchet 2313.

[0034] In this embodiment of the present invention, infrared camera 215 monitors the bag's posture (local tilt) in real time. Electromagnet 216 is activated and controlled on and off via conductive ring 15 / connector, enabling on-demand activation of the second transmission gear 253 of the correcting transmission unit 25 by controlling its engagement and disengagement with rack 14 via electromagnet 216. When electromagnet 216 is energized, the repulsive force overcomes the elastic force of second spring 255, pushing second transmission gear 253 into engagement with rack 14. As pallet module 2 moves along conveyor belt 12, the engaged second transmission gear 253 is "reverse-pushed" by rack 14, converting the conveyor's kinetic energy into rotational power. The correcting unit 24 rotates a certain angle (monitored by an angle sensor), and its curved clamping rod 241 and wing lever 242 act like a "robot arm," stroking or pushing the misaligned or protruding areas of the bag, achieving dynamic correction. This eliminates the need for a separate motor or power source, instead utilizing the conveyor's travel power to drive the correcting mechanism, resulting in energy efficiency and high efficiency.

[0035] Working principle: S100, refer to the attached Figure 11The ton bag is placed on the surface of the tray 221 from the feeding station by the manipulator, and the gravity of the ton bag drives the limiting rod 222 and the ball head rod 224 to descend, the descending ball head rod 224 drives the rotating part 232 to rotate through the sliding connection with the curved guide rail 2323, the rotating rotating part 232 drives the radial moving part 231 and the deviation correcting part 24 to move in the radial hole 212 towards the direction close to the ton bag through the arc-shaped hole 2324, and the arc-shaped clamping rod 241 and the wing rod 242 can limit the ton bag from the warp and weft directions respectively, the moving distance of the radial moving part 231 can be automatically controlled according to the gravity of the ton bag, and the ton bag gravity self-adaptive limiting is realized. S200, the tray module 2 is driven to move on the surface of the circulating conveying table 11 by the conveying belt 12, and the specific process is shown in the following figure. Figure 10 When the infrared lens 215 monitors that the ton bag is locally tilted in the conveying process, the electromagnet 216 is controlled to be electrified through the conductive joint 214 and the conductive ring 15, the magnetic repulsion generated by the electrified electromagnet 216 drives the second transmission gear 253 and the pin rod 254 to move, for driving the second transmission gear 253 to be in transmission connection with the toothed rail 14 (the second transmission gear 253 is in contact with the limiting frame 217), the moving tray module 2 drives the pin rod 254, the transmission pipe 252 and the third transmission gear 256 to rotate through the transmission connection of the second transmission gear 253 and the toothed rail 14 (the pin rod 254 and the transmission pipe 252 are in the key groove and key strip matching structure), the rotating third transmission gear 256 drives the first transmission gear 244 and the deviation correcting part 24 to rotate by a certain angle through the transmission tooth ring 251 (the rotating angle is monitored by the angle sensor integrated on the surface of the rotating shaft 243), the arc-shaped clamping rod 241 and the wing rod 242 for rotating and swinging are used for locally flattening or correcting the tilted or deviated ton bag, and the matching structure of the arc-shaped tooth rod 246 and the ratchet wheel 2313 is used for increasing the rotating damping of the rotating shaft 243; after the deviation correction instruction is completed, the electromagnet 216 is controlled to be de-energized through the conductive joint 214 and the conductive ring 15, and the elastic force of the second spring 255 drives the second transmission gear 253 to be separated from the toothed rail 14. S300, reference is made to the following figure. Figure 9 After reaching the discharging station, the electromagnet 216 is de-energized again through the conductive joint 214 and the conductive ring 15, for controlling the deviation correcting part 24 to rotate 90 degrees around the rotating shaft 243 (the limiting structure 2312 can mechanically limit the deviation correcting part 24 through the protrusion 245), so that the ton bag is taken out by the manipulator.

[0036] In summary, the ton bag gravity and the kinetic energy of the conveyor are utilized in the present application, without additional power, ton bag self-adaptive clamping according to the ton bag gravity during feeding, dynamic deviation correction during conveying and automatic avoidance during discharging are realized, the problems of ton bag size deviation, low efficiency of manual correction and poor adaptability of fixed clamps are solved, and the present application has the characteristics of high efficiency, reduction of manual intervention and self-adaptive correction.
