Description

Technical Field

[0001] The present invention relates to the technical field of intelligent suspension and conveying, and in particular to an intelligent suspension and conveying system for EVA packaging bags. Background Art

[0002] The EVA packaging bag intelligent hanging conveying system is an automated material transfer equipment designed specifically for EVA packaging bags. It integrates hanging conveying technology with intelligent control. It is mainly used in production lines, warehousing or logistics links to achieve efficient and accurate conveying of EVA packaging bags.

[0003] The existing intelligent overhead conveyor system primarily consists of a track system, conveyor chains, and spreaders. In practice, workers manually place EVA bags onto the spreader, which is then connected to the track system via the conveyor chain and moved to the target workstation. When the spreader reaches its target location (such as the packaging machine entrance or a storage shelf), the intelligent system automatically decelerates and accurately positions the spreader, assisting with unloading or storage operations. After unloading, the empty spreader returns to its loading position, entering a recycling state.

[0004] However, in actual applications, since EVA packaging bags are soft and easy to deform, they are prone to swinging, tilting or falling off when hung directly on hooks for transportation, resulting in inaccurate positioning in subsequent transportation, inspection, sorting and other links, affecting overall production efficiency and product quality.

[0005] At the same time, in the existing hanging conveying system, after the EVA packaging bag is hung on the conveying track, since the conveying track is often located at a higher position or has a more compact layout, if the EVA packaging bag is long, it will be difficult for the operator to reach the hook to remove the EVA packaging bag when taking and placing the packaging bag, which significantly reduces the packaging bag processing efficiency per unit time and slows down the operation speed of the entire conveying system.

[0006] Therefore, an intelligent hanging and conveying system for EVA packaging bags is proposed. Summary of the Invention

[0007] The object of the present invention is to provide an intelligent hanging and conveying system for EVA packaging bags to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent hanging and conveying system for EVA packaging bags, comprising a track conveying device and two hooks, the two hooks are rotatably connected to the bottom of the track conveying device, and the bottom ends of the two hooks are jointly provided with an intelligent hanging and conveying assembly, the intelligent hanging and conveying assembly comprises two bolts, the two bolts are respectively clamped in the inside of the two hooks, the ends of the two bolts away from each other are each threadedly connected to a nut, and the ends of the two bolts close to each other are jointly fixedly connected to a support plate, the lower surface of the support plate is fixedly connected to a small motor 1, the small motor 1 is divided into a fixed end and an output shaft, the output shaft end of the small motor 1 is fixedly connected to a wiring pulley 1, three steel ropes 1 are fixedly connected to the wiring pulley 1 in a linear array, the upper surface of the support plate is fixedly connected to a small motor 2, the small motor 2 is divided into a fixed end and an output shaft, the output shaft end of the small motor 2 is fixedly connected to a wiring pulley 2, and three steel ropes 2 are fixedly connected to the wiring pulley 2 in a linear array.

[0009] Furthermore, three connecting rods are fixedly connected in a circular array on the support plate, and the top ends of the three connecting rods away from the support plate are fixedly connected to a guide rod 1, and the bottom ends of the three connecting rods away from the support plate are fixedly connected to a guide rod 2. The ends of the three steel ropes 1 away from the cable pulley 1 are commonly fixedly connected to a cable bag ring 1, and the ends of the three steel ropes 2 away from the cable pulley 2 are commonly fixedly connected to a cable bag ring 2. The inner ring surface of the cable bag ring 1 is fixedly connected to a lifting bag, and a draw rope is wrapped around the bottom end of the lifting bag.

[0010] Furthermore, the length of the support plate is equal to the distance between the two hooks.

[0011] Furthermore, there is an electrical connection between the small motor 1 and the small motor 2 and the intelligent control system of the track conveying device.

[0012] Furthermore, the three steel ropes 1 are distributed in a winding shape on the harness wheel 1, the three steel ropes 2 are distributed in a winding shape on the harness wheel 2, the three steel ropes 1 are arranged in a circular array on the harness wheel 1 and face different directions, and the three steel ropes 2 are arranged in a circular array on the harness wheel 2 and face different directions.

[0013] Furthermore, the single steel wire rope 1 is slidably connected to the guide rod 2 in the corresponding direction, and the single steel wire rope 2 is slidably connected to the guide rod 1 in the corresponding direction.

[0014] Furthermore, the guide rod 1 and the guide rod 2 are both configured to be L-shaped.

[0015] Furthermore, the three steel wire ropes 2 all pass through the draw bag ring 1, and the inner ring surface of the draw bag ring 2 is fixedly connected to the lifting bag.

[0016] Furthermore, the three steel ropes 1 and 2 are distributed in a triangle shape on the outside of the lifting bag.

[0017] Furthermore, the lifting bag is configured to be open at both ends, and the drawstring rope can be wrapped around the bottom end of the lifting bag to tighten it. The drawstring bag ring 1 is located at the top opening position of the lifting bag, and the drawstring bag ring 2 is located at the lower half of the lifting bag.

[0018] Compared with the prior art, the present invention has the following beneficial effects: In the existing technology, EVA packaging bags vary greatly due to factors such as packaging methods and volumes. Through the operation of the intelligent hanging conveying component, the EVA packaging bags are "wrapped" inside the hanging bag, which is equivalent to providing a flexible container for EVA packaging bags of different shapes and volumes, so that they can be stably carried no matter how their shapes change.

[0019] In the existing technology, since EVA packaging bags are soft and easy to deform, they are prone to swing, tilt or even fall off when hung directly on hooks for transportation, affecting the positioning accuracy of subsequent links, and thus affecting the overall production efficiency and product quality. However, through the operation of the intelligent hanging and conveying components, the lifting bag forms an all-round wrapping and fixation of the EVA packaging bag. At the same time, the three steel wire ropes 1 and 2 are distributed in a triangular shape on the lifting bag, and the triangle can form a stable mechanical structure, so that the lifting bag forms a stable support structure during hanging transportation, which greatly enhances the stability of the lifting bag and the internal EVA packaging bag, reduces the risk of swinging and falling of the EVA packaging bag during transportation, and improves the safety and reliability of the transportation process.

[0020] At the same time, the track height in the existing technology is fixed, which makes it difficult to pick up manually, resulting in a long time for a single pick-up and placement. Through the operation of the intelligent suspension conveying component, the user can perform pick-up and placement operations at a more convenient and safer height during the pick-up and placement steps in the suspension conveying process, thereby significantly improving the EVA packaging bag processing efficiency per unit time and accelerating the overall operation speed of the suspension conveying system.

[0021] In addition, the user can adjust the depth of the lifting bag to lift the EVA packaging bag to a position closer to the hook, which is equivalent to reducing the free movement space of the EVA packaging bag inside the lifting bag, reducing the shaking of the EVA packaging bag and the lifting bag during the hanging transportation process due to inertia, external force or track vibration, thereby reducing uncertainty in the transportation process.

[0022] By adjusting the depth of the lifting bag, the EVA packaging bag is positioned closer to the force-bearing fulcrum of the lifting bag, which shortens the distance between the center of gravity of the EVA packaging bag and the suspension fulcrum. Physically, the closer the center of gravity is to the fulcrum, the smaller the inertia moment generated by factors such as track turning and start-stop vibration during transportation, and the shaking of the EVA packaging bag will be significantly reduced.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] The present invention provides the following embodiments: See also Figures 1 to 8 As shown, an intelligent hanging conveying system for EVA packaging bags includes a track conveying device 11 and two hooks 12 , and the two hooks 12 are rotatably connected to the bottom of the track conveying device 11 .

[0027] The track conveying device 11 and the hook 12 are both of the prior art. The track conveying device 11 is composed of a track body, a driving device, and a conveying chain.

[0028] The main rails of the track are fixedly installed along the preset conveying path, such as the straight line, curve, and circular route above the workshop, forming the motion trajectory of the conveyor chain.

[0029] The drive device consists of a servo motor, a reducer and a braking system. The drive device is usually set at key nodes of the track path, such as the starting point of a straight segment and the closed-loop drive position of a circular track, to provide continuous power for the conveyor chain.

[0030] The conveyor chain is embedded in the track body or runs along the outside of the track, and its bottom end is rotated to connect the hook 12 and moves in a direction along the track under the drive of the driving device.

[0031] The bottom ends of the two hooks 12 are jointly provided with an intelligent suspension conveying component, which includes two bolts 21, and the two bolts 21 are respectively clamped in the inside of the two hooks 12, and the ends of the two bolts 21 away from each other are threadedly connected to a nut 22, and the ends of the two bolts 21 close to each other are jointly fixedly connected to a support plate 23, and the lower surface of the support plate 23 is fixedly connected to a small motor 1 24, which is divided into a fixed end and an output shaft, and the output shaft end of the small motor 1 24 is fixedly connected to a cable wheel 1 25, and three steel ropes 1 26 are fixedly connected to the cable wheel 1 25 in a linear array, and the upper surface of the support plate 23 is fixedly connected to a small motor 27, which is divided into a fixed end and an output shaft, and the small motor 22 is fixedly connected to the output shaft end of the small motor 22. The output shaft end of 7 is fixedly connected to a cable pulley 28, and three steel wire ropes 29 are fixedly connected to the cable pulley 28 in a linear array. Three connecting rods 210 are fixedly connected to the support plate 23 in a circular array. The top of the three connecting rods 210 away from the support plate 23 is fixedly connected to a guide rod 1 211, and the bottom end of the three connecting rods 210 away from the support plate 23 is fixedly connected to a guide rod 212. The ends of the three steel wire ropes 1 26 away from the cable pulley 1 25 are commonly fixedly connected to a bag ring 1 213, and the ends of the three steel wire ropes 29 away from the cable pulley 28 are commonly fixedly connected to a bag ring 214. The inner annular surface of the bag ring 1 213 is fixedly connected to a lifting bag 215, and the bottom end of the lifting bag 215 is wrapped with a cinch rope 216.

[0032] Among them: reference Figure 3 、 Figure 7As shown, the length of the support plate 23 is equal to the distance between the two hooks 12. Specifically, the user can insert the two bolts 21 into the inside of the hook 12 from the opening of the hook 12. At this time, the two sides of the support plate 23 are in conflict with the side close to the two hooks 12. The user tightens the two nuts 22 on the corresponding bolts 21, and then the two sides of the two hooks 12 are clamped by the nuts 22 and the support plate 23. In this way, the support plate 23 is installed on the two hooks 12, so that when the hook 12 is driven by the track conveying device 11 for suspended transportation, it can drive the support plate 23 to move synchronously and smoothly.

[0033] It should be noted that: since the track conveying device 11 has special-shaped paths such as loops and curves, which involve the hook 12 turning, when the hook 12 turns, since the hook 12 is rotationally connected to the track conveying device 11, the support plate 23 can follow the two hooks 12 to turn synchronously, so that the support plate 23 can adapt to the special-shaped path of the track conveying device 11.

[0034] Among them: small motor 1 24 and small motor 2 27 are electrically connected to the intelligent control system of the track conveying device 11. The track conveying device 11 is provided with a sensor for detecting the position of the hook 12, which is not shown in the figure. Specifically: when the sensor detects that the hook 12 drives the intelligent suspension conveying component to move to the loading position or the unloading position of the track conveying device 11, the intelligent control system controls small motor 1 24 and small motor 2 27 to start operation.

[0035] Among them: reference Figure 3 、 Figure 6 As shown, two partitions are provided on the harness wheel 1 25 and the harness wheel 2 28, which serve to separate the three wire ropes 1 26 on the harness wheel 1 25 to avoid mutual interference, and to separate the three wire ropes 2 29 on the harness wheel 2 28 to avoid mutual interference. The three wire ropes 1 26 are distributed in a winding shape on the harness wheel 1 25, and the three wire ropes 2 29 are distributed in a winding shape on the harness wheel 2 28.

[0036] Among them, three steel ropes 1 26 are arranged in a circular array on the cable pulley 1 25 and face different directions respectively; three steel ropes 2 29 are arranged in a circular array on the cable pulley 2 28 and face different directions respectively.

[0037] Among them: a single steel wire rope 1 26 is slidably connected to the guide rod 2 212 in the corresponding direction, and a single steel wire rope 2 29 is slidably connected to the guide rod 1 211 in the corresponding direction.

[0038] Among them: reference Figure 6As shown, guide rod 1 211 and guide rod 2 212 are both set to L-shape, and their function is to change the moving path of wire rope 1 26 and wire rope 2 29 so that the moving path of the bottom end of wire rope 1 26 and wire rope 2 29 is vertically upward or downward.

[0039] Among them: reference Figure 6 As shown, the three steel ropes 29 all pass through the drawstring ring 1 213.

[0040] Among them, the inner ring surface of the second bag ring 214 is fixedly connected to the lifting bag 215.

[0041] The lifting bag 215 is configured to be open at both ends, and the drawstring 216 can be wound around the bottom end of the lifting bag 215 to tighten it.

[0042] The first draw bag ring 213 is located at the top opening of the lifting bag 215 , and the second draw bag ring 214 is located at the lower half of the lifting bag 215 .

[0043] Please note: Refer to Figure 1 、 Figure 8 As shown, three steel ropes 1 26 and three steel ropes 2 29 are distributed in a triangle shape on the outside of the lifting bag 215.

[0044] It should be noted that in the prior art, a plurality of hooks 12 are provided at the bottom of the track conveying device 11 , and an intelligent suspension conveying component is provided between every two hooks 12 , and only one is shown in the figure.

[0045] When the intelligent hanging conveying component is running, that is, it is at the loading position of the track conveying device 11, the user needs to hang the EVA packaging bag to the picking position, at this time, the lifting bag 215 is at the loading position of the track conveying device 11, and the drawstring rope 216 tightens the bottom end of the lifting bag 215, so that only the top of the lifting bag 215 is open. At this time, the sensor on the track conveying device 11 detects that the hook 12 drives the lifting bag 215 to be at the loading position, the intelligent control system of the track conveying device 11 synchronously starts the small motor 1 24 and the small motor 2 27, so that the output ends of the small motor 1 24 and the small motor 2 27 rotate, driving the wire pulley 1 25 and the wire pulley 2 28 to rotate synchronously, and the rotation of the wire pulley 1 25 and the wire pulley 2 28 causes the three steel wire ropes 1 26 and the steel wire rope 2 29 to unwind, and then the bag ring 1 213 and the bag ring 2 214 drive the lifting bag 215 to descend. When the lifting bag 215 falls to the user's convenience When in the operating position, the intelligent control system of the track conveying device 11 stops the operation of small motor 1 24 and small motor 2 27, so that the position of the lifting bag 215 is fixed. At this time, the user puts the EVA packaging bag to be conveyed into the lifting bag 215 from the top opening position of the lifting bag 215. Since the drawstring rope 216 tightens the bottom end of the lifting bag 215 at this time, the EVA packaging bag is loaded into the lifting bag 215. After completion, the intelligent control system of the track conveying device 11 synchronously starts small motor 1 24 and small motor 2 27, so that the output ends of small motor 1 24 and small motor 2 27 rotate in opposite directions, and then small motor 1 24 and small motor 2 27 drive the cable wheel 1 25 and the cable wheel 2 28 to reel, so that the lifting bag 215 rises in height, that is, the lifting bag 215 drives the EVA packaging bag to be suspended. At this time, the lifting bag 215 drives the internal EVA packaging bag to move and transport it to the pickup position.

[0046] During this process, the user can start the small motor 27 separately through the intelligent control system of the track conveying device 11 according to the height of the EVA packaging bag inside the lifting bag 215, so that the output shaft of the small motor 27 rotates and drives the cable wheel 28 to reel. At this time, the cable wheel 28 drives the three steel wire ropes 29 to reel, and the three steel wire ropes 29 drive the bag ring 214 to move upward, and the bag ring 214 drives the lifting bag 215 to move upward. During this process, the bag ring 1 213 remains stationary. The lifting bag 215 moves, that is, the bottom end of the lifting bag 215 rises while the top end does not move, forming a process in which the cavity of the lifting bag 215 becomes shallower, and under the action of gravity, the EVA packaging bag is located at the bottom end inside the lifting bag 215, that is, the height of the EVA packaging bag inside the lifting bag 215 gradually becomes smaller. When the EVA packaging bag is about to be exposed inside the lifting bag 215, the intelligent control system of the track conveying device 11 turns off the small motor 27 to fix the height of the lifting bag 215 and the position of the EVA packaging bag inside the lifting bag 215.

[0047] When the lifting bag 215 drives the internal EVA packaging bag to move to the pickup position, the sensor on the track conveying device 11 detects that the hook 12 drives the lifting bag 215 to the pickup position, and the intelligent control system of the track conveying device 11 starts the small motor 1 24 and the small motor 2 27, so that the cable wheel 1 25 and the cable wheel 2 28 unwind. At the same time as the cable wheel 1 25 and the cable wheel 2 28 unwind, the lifting bag 215 drives the EVA packaging bag to move downward. When it moves to a height that is convenient for the user to take out, the intelligent control system of the track conveying device 11 turns off the small motor 1 24 and the small motor 2 27. At this time, the user can untie the drawstring 216 to expose the bottom of the lifting bag 215 and take out the EVA packaging bag from the opening position at the bottom of the lifting bag 215. After completion, the user ties the bottom of the lifting bag 215 tightly with the drawstring 216, and the intelligent control system of the track conveying device 11 controls the small motor 1 24 and the small motor 2 27 to move the lifting bag 215 upward.

[0048] In summary, during the operation of the above intelligent suspension conveying components, In the prior art, EVA packaging bags vary greatly due to factors such as packaging methods and volumes. Through the operation of the intelligent hanging conveying component, the EVA packaging bags are "wrapped" inside the hanging bag 215, which is equivalent to providing a flexible container for EVA packaging bags of different shapes and volumes, so that they can be stably carried no matter how their shapes change.

[0049] In the prior art, since EVA packaging bags are soft and easily deformed, they are prone to swing, tilt, or even fall off when directly hung on the hook 12 for transportation, affecting the positioning accuracy of subsequent links, and thus affecting the overall production efficiency and product quality. However, through the operation of the intelligent suspension conveying component, the lifting bag 215 forms an all-round wrapping and fixation of the EVA packaging bag. At the same time, the three steel wire ropes 26 and the steel wire ropes 2 29 are distributed in a triangular shape on the lifting bag 215, and the triangle can form a stable mechanical structure, so that the lifting bag 215 forms a stable support structure during suspension transportation, which greatly enhances the stability of the lifting bag 215 and the internal EVA packaging bag, reduces the risk of swinging and falling of the EVA packaging bag during transportation, and improves the safety and reliability of the transportation process.

[0050] At the same time, the track height in the existing technology is fixed, which makes it difficult to pick up manually, resulting in a long time for a single pick-up and placement. Through the operation of the intelligent suspension conveying component, the user can perform pick-up and placement operations at a more convenient and safer height during the pick-up and placement steps in the suspension conveying process, thereby significantly improving the EVA packaging bag processing efficiency per unit time and accelerating the overall operation speed of the suspension conveying system.

[0051] In addition, the user can adjust the height of the lifting bag 215 to lift the EVA packaging bag to a position closer to the hook 12, which is equivalent to reducing the free movement space of the EVA packaging bag inside the lifting bag 215, reducing the shaking of the EVA packaging bag and the lifting bag 215 during the hanging transportation process due to inertia, external force or track vibration, thereby reducing uncertainty in the transportation process.

[0052] In addition, by adjusting the height of the lifting bag 215, the position of the EVA packaging bag is brought closer to the force fulcrum of the lifting bag 215, that is, the distance between the center of gravity of the EVA packaging bag and the suspension fulcrum is shortened. At the physical level, the closer the center of gravity is to the fulcrum, the smaller the inertia moment generated by factors such as track turning and start-stop vibration during transportation, and the shaking of the EVA packaging bag will be significantly reduced.

[0053] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
