Description

Technical Field

[0001] The present invention relates to the technical field of logistics and transportation, and in particular to logistics loading and unloading equipment with a multi-angle adjustment function. Background Art

[0002] In today's booming logistics industry, the efficiency and quality of cargo loading and unloading are directly related to the smooth operation of the entire logistics supply chain. Traditional logistics loading and unloading equipment has many functional limitations and cannot meet the growing logistics needs, urgently needing innovation and improvement.

[0003] First, traditional logistics loading and unloading equipment has a single loading angle, severely lacking flexibility when handling cargo of varying vehicle types, placement positions, and heights. Furthermore, during transportation, cargo can easily shift or tilt after loading due to vehicle jolting and improper handling. Existing logistics loading and unloading equipment has limited capabilities for correcting cargo, and most rely on manual post-loading adjustments, resulting in low efficiency and poor results. Manual correction is particularly challenging for large and heavy cargo.

[0004] Secondly, accurately understanding the packing density of cargo is crucial for optimizing transportation space utilization and ensuring cargo safety. Currently, determining packing density mainly relies on manual observation and simple measurement tools, which are highly subjective and inaccurate.

[0005] Finally, during loading, especially when fully loaded, friction between cargo and equipment, and between cargo and cargo, can easily generate static electricity. The accumulation of static electricity can lead to a range of serious problems. For some flammable and explosive goods, static discharge can cause fires or explosions, resulting in significant loss of life and property. For electronic goods, static electricity can damage electronic components, affecting product quality. Summary of the Invention

[0006] The purpose of the present invention is to provide a logistics loading and unloading equipment with multi-angle adjustment function to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

The conveying frame is placed on a horizontal basis, the conveying frame is fixedly connected to the conveying unit, the correction unit is fixedly installed on the conveying frame, the correction unit has the function of correcting items, the detection unit is fixedly connected to the conveying frame, the detection unit has the function of determining whether the goods are fully loaded and removing static electricity, and the controller is fixedly installed on the conveying frame.

[0009] The conveyor rack is used to install and fix the conveying unit, correction unit, detection unit and controller. The conveying unit is used to convey items, the correction unit is used to adjust the posture of tilted items, the detection unit is used to check the tightness of loaded items and eliminate static electricity, and the controller is used to control the start and stop of the conveying unit, correction unit and detection unit. After the correction unit corrects the posture of the item, it is clamped and placed on the conveying unit, and the item is transported to the vehicle through the conveying unit. The detection unit determines the tightness of the loading based on the sound and eliminates static electricity on the fully loaded goods, avoiding damage to components of electronic goods and combustion and explosion caused by static electricity, thereby ensuring the integrity and safety of the goods.

[0010] Furthermore, the conveying unit includes a conveying motor, a conveyor belt, a conveyor roller and an electric telescopic rod. The fixed end of the conveying motor is fixedly installed on the conveying frame, the output end of the conveying motor is fixedly connected to one end of the conveying roller, and the other end of the conveying roller is rotatably connected to the conveying frame. The conveyor belt is covered on the outer surface of the conveyor roller, the fixed end of the electric telescopic rod is fixedly installed on the conveying frame, and the telescopic end of the electric telescopic rod is fixedly connected to the rotating end of the conveying frame.

[0011] The controller controls the start of the conveyor motor, thereby driving the conveyor roller to rotate, so that the goods on the conveyor belt are transported to the designated vehicle or area. When it is necessary to adjust the tilt angle at different heights and stack the items at different heights neatly, the controller controls the electric telescopic rod to extend and retract to different lengths to adjust different angles, providing multi-angle placement of items and improving flexibility.

[0012] Furthermore, the correction unit includes an electric telescopic rod 2, a connecting plate, a semi-toothed plate, a gear, a pull rope, a right-angle rod, a first electric telescopic plate and a second electric telescopic plate. The fixed end of the electric telescopic rod 2 is fixedly installed on the conveying frame, the output end of the electric telescopic rod 2 is fixedly connected to the connecting plate, one end of the connecting plate is rotatably connected to the conveying frame, and the other end is fixedly connected to the fixed end of the first electric telescopic plate. The semi-toothed plate is fixedly installed on the connecting plate, the gear is rotatably installed on the conveying frame through a connecting round rod, the pull rope is wrapped around the end of the connecting round rod between the gear and the conveying frame, and the right-angle rod is fixedly connected to the fixed end of the second electric telescopic plate.

[0013] Furthermore, the correction unit also includes a column, a winding rod, a protective plate, a drive motor, a clamping plate, a photoresistor, an air pump, an electromagnet, a buffer airbag and a blocking cover. The column is slidably connected to the telescopic end of the second electric telescopic plate, the column is fixedly connected to the telescopic end of the first electric telescopic plate, the winding rod is fixedly connected to the telescopic end of the first electric telescopic plate, the protective plate is rotatably connected to the column, the protective plate is connected to the connecting rod of the gear by a pull rope passing around the winding rod, the fixed end of the drive motor is fixedly installed on the telescopic end of the first electric telescopic plate, the output end of the drive motor is fixedly connected to the clamping plate, and the photoresistor is fixed. It is installed at the telescopic end of the first electric telescopic plate, the air pump is fixedly installed on the conveying frame, and two air outlets are provided on the air pump. The electromagnet consists of an upper electromagnet and a lower electromagnet. The upper electromagnet is fixedly installed on the lower surface of the fixed end of the first electric telescopic plate, and the lower electromagnet is fixedly installed on the upper surface of the fixed end of the second electric telescopic plate. The buffer airbag is fixedly installed on one end of the clamping plate for clamping the goods. The buffer airbag is connected to the air outlet of the air pump through a pipeline. The blocking cover is fixedly connected to one end of the right-angle rod. The blocking cover is slidably installed at the air outlet of the air pump, and the blocking cover is located in the pipeline.

[0014] When the cargo in the vehicle tilts due to driving bumps, the controller controls the drive motor to start, driving the clamping plate to rotate to both sides of the cargo. At the same time, the electric telescopic rod 2 is started, pushing the connecting plate to rotate from bottom to top around the conveyor frame. In the process of straightening the tilted cargo, the semi-toothed plate drives the gear to rotate clockwise, thereby winding the pull rope around the connecting round rod. As the pull rope winds, the protective plate is pulled around the winding rod to rotate around the column, so that the two protective plates are close to each other. For small cargo, the cargo is pushed to the designated clamping position. For large cargo, the blocking effect of the two protective plates avoids the forward rollover caused by unstable center of gravity during the gradual correction of the tilted cargo, thereby further ensuring the safety of the cargo. In the process of straightening the clamping plate from bottom to top, the pressure of the tilted cargo on one side of the clamping plate is greater than that on the other side. At this time, the film is pressed The force sensor detects the pressure on both sides of the clamping plate and converts it into an electrical signal to be transmitted to the controller. When the pressure on one side of the clamping plate is too large, the controller transmits a large current to the upper electromagnet on that side, thereby increasing the magnetism of the upper electromagnet and driving the lower electromagnet to move upward. At this time, the sealing cover moves upward under the transmission action of the right-angle rod, thereby increasing the flow rate of the air pump outlet, and the gas of the air pump is delivered to the buffer airbag of the clamping plate on the pressure side, providing sufficient buffering protection for the tilted goods, avoiding direct contact between the clamping plate and the goods when correcting the goods, causing damage to the goods. When the first electric telescopic plate moves to the upper end of the goods, the posture correction of the goods is completed. At this time, when the photoresistor re-detects strong light, the controller controls the second electric telescopic rod to retract while controlling the drive motor to clamp the goods. The first electric telescopic plate and the second electric telescopic plate retract a distance to clamp the goods on the conveyor belt for transportation.

[0015] Furthermore, the detection unit includes an electric push rod, a slide, a resonance chamber, a vibration plate, an arc push rod, a support plate, a drive coil and a bar magnet. The fixed end of the electric push rod is fixedly mounted on the conveying frame, the output end of the electric push rod is fixedly connected to the slide, the slide is rotatably mounted on the conveying frame, the resonance chamber is fixedly mounted on the lower surface of the slide, the vibration plate is vertically fixedly mounted on the inner surface of the resonance chamber, the arc push rod is fixedly mounted on the side surface of the vibration plate, the support plate is fixedly mounted on the inner wall of the resonance chamber, the drive coil is fixedly mounted on the lower surface of the support plate, and the bar magnet is fixedly mounted on the end of the arc push rod close to one end of the support plate.

[0016] Furthermore, the detection unit also includes a straight plate, a roller, metal bristles, a rotating motor, a long rod, a paddle and a grounded metal plate. One end of the straight plate is fixedly connected to the outer surface of the resonance chamber, and the other end is rotatably connected to the roller. Multiple groups of metal bristles are provided on the outer surface of the roller. The fixed end of the rotating motor is fixedly mounted on the straight plate, the output end of the rotating motor is fixedly connected to the roller, the long rod is fixedly mounted on the end of the roller away from the rotating motor, the paddle is rotatably mounted on the lower surface of the slide, and the grounded metal plate is mounted below the slide through a connecting rod. The grounded metal plate is located below the roller.

[0017] When the goods are transported to the slide, the controller controls the electric push rod to retract a certain distance and slide the goods to the specified area and specified height in the car, thereby realizing multi-angle adaptive loading of goods. The sound generated when the goods are loaded into the car is different. When it is fully loaded, the sound of the frequency enters the resonance chamber, causing the vibration plate to vibrate, thereby driving the arc push rod to drive the bar magnet into the drive coil under the support plate. At this time, the magnetic flux changes, thereby generating current in the drive coil. After the controller detects the generation of current in the drive coil, it controls the rotary motor to start, driving the drum to rotate, thereby causing the metal bristles on the drum to rotate, forming an electric potential difference with the grounded metal plate, and the metal The bristles of the brush continuously rub against the air during rotation, ionizing the air to produce ions. These ions neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. The long rod is driven to rotate during the rotation of the drum, periodically pushing the paddle to swing, and pushing the surrounding air forward when the paddle is reset, thereby quickly pushing the generated ions to the surface of the goods, thereby increasing the rate of eliminating static electricity on fully loaded goods. In addition, when loading is completed, the staff can observe whether the drum is rotating to determine the tightness of the cargo loading. When gaps appear in the loading, manual adjustments can be made, thereby improving loading efficiency and transportation space utilization, while avoiding damage to the goods caused by loading too loose or too tight.

[0018] Furthermore, a thin film pressure sensor is provided at the contact end between the buffer airbag and the clamping plate.

[0019] In order to detect the pressure on one side of the tilted cargo, the lower electromagnet is controlled to drive the second electric telescopic plate to move up, so that the blocking plate moves up to increase the air pump flow, thereby adjusting the gas delivery volume of the buffer airbag on that side, providing sufficient buffer protection for the tilted cargo, and preventing the clamping plate from directly contacting the cargo when correcting the cargo, causing damage to the cargo.

[0020] Furthermore, the gear ratio between the half-toothed plate and the gear is in the range of 3:1 to 6:1.

[0021] When correcting tilted cargo, the guard plate's rotation angle must be precisely controlled to ensure effective contact with the cargo and appropriate corrective force. When the ratio of the half-toothed plate to the gear is within this range, precise rotation control is achieved, ensuring accurate correction. This prevents excessive or insufficient rotation, which can lead to poor correction results and even secondary damage to the cargo.

[0022] Furthermore, the magnetism of the upper electromagnet is opposite to that of the lower electromagnet.

[0023] The receiving current of the upper electromagnet increases the magnetism, driving the lower electromagnet to move upward, thereby changing the area of ​​the blocking outlet of the blocking cover, so that the buffer airbag on the clamping plate on the side with greater pressure provides sufficient gas, thereby buffering the pressure of the goods on the clamping plate, avoiding damage to the goods during the correction process and destroying the integrity of the goods.

[0024] Furthermore, the conveyor frame is provided with rollers.

[0025] The rollers enable the conveyor rack to be easily moved on various surfaces without the need for manual handling or dragging, which greatly reduces the physical burden. In situations where boxes need to be moved frequently, the rollers can significantly improve the moving efficiency.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When it is necessary to adjust the tilt angle at different heights and stack items at different heights neatly, the present invention controls the electric telescopic rod to extend and retract to different lengths to adjust different angles through the controller, providing multi-angle item placement and improving flexibility. At the same time, when the goods are transported to the slide, the controller controls the electric push rod to retract a certain distance and slide the goods to the specified area and specified height in the vehicle, thereby realizing multi-angle adaptive loading of goods.

[0028] 2. The present invention works by pushing the connecting plate to rotate from bottom to top around the conveyor frame when the cargo in the vehicle is tilted due to driving bumps, driving the semi-toothed plate to drive the gear to rotate clockwise, and the winding rope drives the protective plates to move closer to each other, pushing small cargo to the designated clamping position. For large cargo, the blocking effect of the two protective plates avoids the tilting cargo from being tilted in the front and rear directions due to the unstable center of gravity during the correction process, thereby ensuring the safety of the cargo. During the righting action of the clamping plate from bottom to top, when the pressure on one side of the clamping plate is too large, the controller transmits a large current to the upper electromagnet on that side, driving the lower electromagnet to move upward, causing the sealing cover to move upward, thereby increasing the flow rate of the air pump outlet, and the gas of the air pump is delivered to the buffer airbag of the clamping plate on the pressure side, providing sufficient buffering protection for the tilted cargo, and avoiding direct contact between the clamping plate and the cargo when correcting the cargo, thereby causing damage to the cargo.

[0029] 3. The present invention allows the sound of the frequency when the cargo is fully loaded to enter the resonance chamber, causing the vibration plate to vibrate, driving the bar magnet on the arc push rod to enter the drive coil, changing the magnetic flux and generating current in the drive coil. After the controller detects the generation of current in the drive coil, it controls the rotary motor to drive the drum to rotate, thereby causing the metal bristles on the drum to rotate, forming a potential difference with the grounded metal plate. The metal bristles rub against the air, causing the air to ionize and generate ions. These ions neutralize the static electricity on the surface of the cargo, thereby eliminating static electricity. During the rotation of the drum, the long rod is driven to rotate, periodically pushing the paddle to swing, and pushing the surrounding air forward when the paddle is reset, thereby quickly pushing the generated ions to the surface of the cargo, thereby improving the static electricity elimination rate of the fully loaded cargo.

[0030] 4. When loading is completed, the staff can observe whether the roller is rotating to determine the tightness of the cargo loading. When there is a gap in the loading, manual adjustment can be made, thereby improving loading efficiency and transportation space utilization, while avoiding damage to the cargo due to loading too loose or too tight.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example: Figures 1-8 As shown, the present invention provides a technical solution:

[0042] like Figure 1 As shown, a logistics loading and unloading equipment with multi-angle adjustment function includes a conveyor frame 1, a conveying unit 2, a correction unit 3, a detection unit 4 and a controller 5. The conveyor frame 1 is placed on a horizontal basis, the conveyor frame 1 is fixedly connected to the conveying unit 2, the correction unit 3 is fixedly installed on the conveyor frame 1, and the correction unit 3 has the function of correcting items. The detection unit 4 is fixedly connected to the conveyor frame 1, and the detection unit 4 has the function of determining whether the goods are fully loaded and removing static electricity. The controller 5 is fixedly installed on the conveyor frame 1.

[0043] The conveyor frame 1 is used to install and fix the conveying unit 2, the correction unit 3, the detection unit 4 and the controller 5.

The detection unit 4 determines the tightness of the loading based on the sound and eliminates static electricity of the fully loaded goods at the same time, avoiding damage to components of electronic goods and combustion and explosion caused by static electricity, thereby ensuring the integrity and safety of the goods.

[0044] like Figure 2 、 4 As shown, the conveying unit 2 includes a conveying motor 21, a conveyor belt 22, a conveyor roller 23 and an electric telescopic rod 24. The fixed end of the conveying motor 21 is fixedly installed on the conveying frame 1, the output end of the conveying motor 21 is fixedly connected to one end of the conveying roller 23, the other end of the conveying roller 23 is rotatably connected to the conveying frame 1, the conveyor belt 22 is covered on the outer surface of the conveyor roller 23, the fixed end of the electric telescopic rod 24 is fixedly installed on the conveying frame 1, and the telescopic end of the electric telescopic rod 24 is fixedly connected to the rotating end of the conveying frame 1.

[0045] The controller 5 controls the conveying motor 21 to start, thereby driving the conveying roller 23 to rotate, so that the goods on the conveyor belt 22 are transported to the designated vehicle or area. When it is necessary to adjust the tilt angle of different heights and stack the items at different heights neatly, the controller 5 controls the electric telescopic rod 24 to extend and retract different lengths to adjust different angles, providing multi-angle placement of items and improving flexibility.

[0046] like Figure 4 As shown, the correction unit 3 includes an electric telescopic rod 2 31, a connecting plate 32, a semi-toothed plate 33, a gear 34, a pull rope 35, a right-angle rod 36, a first electric telescopic plate 37 and a second electric telescopic plate 38. The fixed end of the electric telescopic rod 2 31 is fixedly mounted on the conveying frame 1, the output end of the electric telescopic rod 2 31 is fixedly connected to the connecting plate 32, one end of the connecting plate 32 is rotatably connected to the conveying frame 1, and the other end is fixedly connected to the fixed end of the first electric telescopic plate 37, the semi-toothed plate 33 is fixedly mounted on the connecting plate 32, the gear 34 is rotatably mounted on the conveying frame 1 through the connecting round rod, the pull rope 35 is wrapped around the end of the connecting round rod between the gear 34 and the conveying frame 1, and the right-angle rod 36 is fixedly connected to the fixed end of the second electric telescopic plate 38.

[0047] like Figure 4 、 5As shown, the correction unit 3 also includes a column 39, a winding rod 310, a protective plate 311, a drive motor 312, a clamping plate 313, a photoresistor 314, an air pump 315, an electromagnet 316, a cushioning airbag 317 and a blocking cover 318. The column 39 is slidably connected to the telescopic end of the second electric telescopic plate 38, the column 39 is fixedly connected to the telescopic end of the first electric telescopic plate 37, the winding rod 310 is fixedly connected to the telescopic end of the first electric telescopic plate 37, the protective plate 311 is rotatably connected to the column 39, the protective plate 311 is connected to the connecting rod of the gear 34 by a pull rope 35 passing around the winding rod 310, the fixed end of the drive motor 312 is fixedly installed on the telescopic end of the first electric telescopic plate 37, the output end of the drive motor 312 is fixedly connected to the clamping plate 313, the photoresistor The resistor 314 is fixedly mounted on the telescopic end of the first electric telescopic plate 37, the air pump 315 is fixedly mounted on the conveying frame 1, and two air outlets are provided on the air pump 315. The electromagnet 316 consists of an upper electromagnet 3161 and a lower electromagnet 3162. The upper electromagnet 3161 is fixedly mounted on the lower surface of the fixed end of the first electric telescopic plate 37, and the lower electromagnet 3162 is fixedly mounted on the upper surface of the fixed end of the second electric telescopic plate 38. The buffer airbag 317 is fixedly mounted on one end of the clamping plate 313 for clamping the goods. The buffer airbag 317 is conductively connected to the air outlet of the air pump 315 through a pipeline. The blocking cover 318 is fixedly connected to one end of the right-angle rod 36. The blocking cover 318 is slidably mounted at the air outlet of the air pump 315. The blocking cover 318 is located in the pipeline.

[0048] When the load is tilted due to the bumps in the vehicle, the controller 5 controls the driving motor 312 to start, driving the clamping plate 313 to rotate to the sides of the load, and at the same time, the electric telescopic rod 21 is started, pushing the connecting plate 32 to rotate from bottom to top around the conveyor frame 1, and in the process of straightening the tilted load, driving the semi-toothed plate 33 to drive the gear 34 to rotate clockwise, thereby winding the pull rope 35 around the connecting round rod, and as the pull rope 35 winds up, it pulls the protective plate 311 around the winding rod 310 to rotate around the column 39, so that the two protective plates 311 are close to each other. For small loads, the load is pushed to the designated clamping position. For large loads, the blocking effect of the two protective plates 311 prevents the tilted load from tipping forward due to the unstable center of gravity during the gradual correction process, further ensuring the safety of the load. In the process of straightening the clamping plate 313 from bottom to top, since the pressure of the tilted load on the clamping plate 313 on one side is greater than that on the other side, the clamping plate 313 detected by the film pressure sensor is The pressure on both sides of the holding plate 313 is converted into an electrical signal and transmitted to the controller 5. When the pressure on one side of the clamping plate 313 is too large, the controller 5 transmits a large current to the upper electromagnet 3161 on that side, thereby increasing the magnetism of the upper electromagnet 3161 and driving the lower electromagnet 3162 to move upward. At this time, the blocking cover 318 moves upward under the transmission action of the right-angle rod 36, thereby increasing the flow rate of the air outlet of the air pump 315. The gas of the air pump 315 is transmitted to the buffer air bag 317 of the clamping plate 313 on the pressure side to tilt the cargo. The object provides sufficient buffer protection to prevent the clamping plate 313 from directly contacting the goods when correcting the goods and causing damage to the goods. When the first electric telescopic plate 37 moves to the upper end of the goods, the posture correction of the goods is completed. At this time, when the photoresistor 314 re-detects strong light, the controller 5 controls the electric telescopic rod 21 to retract and controls the drive motor 312 to clamp the goods. The first electric telescopic plate 37 and the second electric telescopic plate 38 retract a distance to clamp the goods on the conveyor belt 22 for transportation.

[0049] like Figure 3 、 6 As shown in , 7 and 8, the detection unit 4 includes an electric push rod 41, a slide 42, a resonance chamber 43, a vibration plate 44, an arc push rod 45, a support plate 46, a drive coil 47 and a bar magnet 48. The fixed end of the electric push rod 41 is fixedly mounted on the conveying frame 1, the output end of the electric push rod 41 is fixedly connected to the slide 42, the slide 42 is rotatably mounted on the conveying frame 1, the resonance chamber 43 is fixedly mounted on the lower surface of the slide 42, the vibration plate 44 is vertically fixedly mounted on the inner surface of the resonance chamber 43, the arc push rod 45 is fixedly mounted on the side surface of the vibration plate 44, the support plate 46 is fixedly mounted on the inner wall of the resonance chamber 43, the drive coil 47 is fixedly mounted on the lower surface of the support plate 46, and the bar magnet 48 is fixedly mounted on the end of the arc push rod 45 close to one end of the support plate 46.

[0050] like Figure 3 、 6 As shown in , 7, the detection unit 4 also includes a straight plate 49, a roller 410, metal bristles 411, a rotating motor 412, a long rod 413, a paddle 414 and a grounded metal plate 415. One end of the straight plate 49 is fixedly connected to the outer surface of the resonance chamber 43, and the other end is rotatably connected to the roller 410. A plurality of groups of metal bristles 411 are provided on the outer surface of the roller 410. The fixed end of the rotating motor 412 is fixedly mounted on the straight plate 49, and the output end of the rotating motor 412 is fixedly connected to the roller 410. The long rod 413 is fixedly mounted on the end of the roller 410 away from the rotating motor 412. The paddle 414 is rotatably mounted on the lower surface of the slide 42. The grounded metal plate 415 is mounted below the slide 42 through a connecting rod. The grounded metal plate 415 is located below the roller 410.

[0051] When the goods are transported to the slide 42, the controller 5 controls the electric push rod 41 to retract a certain distance, and slide the goods to the specified area and specified height in the vehicle, thereby realizing multi-angle adaptive loading of goods. The sound generated when the goods are loaded into the vehicle is different. When it is fully loaded, the sound of the frequency enters the resonance chamber 43, causing the vibration plate 44 to vibrate, thereby driving the arc push rod 45 to drive the bar magnet 48 into the driving coil 47 under the support plate 46. At this time, the magnetic flux changes, thereby generating current in the driving coil 47. After the controller 5 detects the generation of current in the driving coil 47, it controls the rotating motor 412 to start, driving the roller 410 to rotate, thereby causing the metal bristles 411 on the roller 410 to rotate accordingly, and contacting the grounded metal plate 415 forms an electric potential difference, and the metal bristles 411 continuously rub against the air during the rotation process, ionizing the air to produce ions, which neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller 410, it drives the long rod 413 to rotate, periodically pushing the dial plate 414 to swing, and pushing the surrounding air forward when the dial plate 414 is reset, thereby quickly pushing the generated ions to the surface of the goods, thereby improving the static electricity elimination rate of the fully loaded goods. In addition, when loading is completed, the staff can observe whether the roller 410 is rotating to determine the tightness of the cargo loading. When gaps appear in the loading, manual adjustments can be made, thereby improving loading efficiency and transportation space utilization, while avoiding damage to the goods caused by loading too loose or too tight.

[0052] like Figure 5 As shown, a thin film pressure sensor is provided at the contact end between the buffer airbag 317 and the clamping plate 313 .

[0053] In order to detect the pressure on one side of the tilted cargo, the lower electromagnet 3162 is controlled to drive the second electric telescopic plate 38 to move upward, so that the blocking plate moves up to increase the flow of the air pump 315, thereby adjusting the gas delivery volume of the buffer airbag 317 on that side, providing sufficient buffer protection for the tilted cargo, and preventing the clamping plate 313 from directly contacting the cargo when correcting the cargo, thereby preventing damage to the cargo.

[0054] like Figure 4 As shown, the gear ratio of the half-toothed plate 33 to the gear 34 is in the range of 3:1 to 6:1.

[0055] When correcting tilted cargo, the rotation angle of the guard plate 311 must be precisely controlled to ensure effective contact with the cargo and the appropriate corrective force. When the tooth ratio of the half-toothed plate 33 to the gear 34 is within this range, precise rotation control is achieved, ensuring accurate correction. This prevents excessive or insufficient rotation, which can lead to poor correction results and even secondary damage to the cargo.

[0056] like Figure 5 As shown, the magnetism of the upper electromagnet 3161 is opposite to the magnetism of the lower electromagnet 3162.

[0057] The receiving current of the upper electromagnet 3161 increases the magnetism, driving the lower electromagnet 3162 to move upward, thereby changing the area of ​​the blocked air outlet of the blocking cover 318, so that the buffer airbag 317 on the clamping plate 313 on the side with greater pressure can provide sufficient gas, thereby buffering the pressure of the goods on the clamping plate 313, avoiding damage to the goods during the correction process and destroying the integrity of the goods.

[0058] like Figure 1 As shown, the conveying frame 1 is provided with rollers.

[0059] The rollers enable the conveyor frame 1 to be easily moved on various surfaces without manual handling or dragging, which greatly reduces the physical burden. In situations where boxes need to be moved frequently, the rollers can significantly improve the moving efficiency.

[0060] Working principle of the present invention:

[0061] The controller 5 controls the conveying motor 21 to start, thereby driving the conveying roller 23 to rotate, so that the goods on the conveyor belt 22 are transported to the designated vehicle or area. When it is necessary to adjust the tilt angle of different heights and stack the items at different heights neatly, the controller 5 controls the electric telescopic rod 24 to extend and retract different lengths to adjust different angles, providing multi-angle placement of items and improving flexibility.

[0062] When the load is tilted due to the bumps in the vehicle, the controller 5 controls the driving motor 312 to start, driving the clamping plate 313 to rotate to the sides of the load, and at the same time, the electric telescopic rod 21 is started, pushing the connecting plate 32 to rotate from bottom to top around the conveyor frame 1, and in the process of straightening the tilted load, driving the semi-toothed plate 33 to drive the gear 34 to rotate clockwise, thereby winding the pull rope 35 around the connecting round rod, and as the pull rope 35 winds up, it pulls the protective plate 311 around the winding rod 310 to rotate around the column 39, so that the two protective plates 311 are close to each other. For small loads, the load is pushed to the designated clamping position. For large loads, the blocking effect of the two protective plates 311 prevents the tilted load from tipping forward due to the unstable center of gravity during the gradual correction process, further ensuring the safety of the load. In the process of straightening the clamping plate 313 from bottom to top, since the pressure of the tilted load on the clamping plate 313 on one side is greater than that on the other side, the clamping plate 313 detected by the film pressure sensor is The pressure on both sides of the holding plate 313 is converted into an electrical signal and transmitted to the controller 5. When the pressure on one side of the clamping plate 313 is too large, the controller 5 transmits a large current to the upper electromagnet 3161 on that side, thereby increasing the magnetism of the upper electromagnet 3161 and driving the lower electromagnet 3162 to move upward. At this time, the blocking cover 318 moves upward under the transmission action of the right-angle rod 36, thereby increasing the flow rate of the air outlet of the air pump 315. The gas of the air pump 315 is transmitted to the buffer air bag 317 of the clamping plate 313 on the pressure side to tilt the cargo. The object provides sufficient buffer protection to prevent the clamping plate 313 from directly contacting the goods when correcting the goods and causing damage to the goods. When the first electric telescopic plate 37 moves to the upper end of the goods, the posture correction of the goods is completed. At this time, when the photoresistor 314 re-detects strong light, the controller 5 controls the electric telescopic rod 21 to retract and controls the drive motor 312 to clamp the goods. The first electric telescopic plate 37 and the second electric telescopic plate 38 retract a distance to clamp the goods on the conveyor belt 22 for transportation.

[0063] When the goods are transported to the slide 42, the controller 5 controls the electric push rod 41 to retract a certain distance, and slide the goods to the specified area and specified height in the vehicle, thereby realizing multi-angle adaptive loading of goods. The sound generated when the goods are loaded into the vehicle is different. When it is fully loaded, the sound of the frequency enters the resonance chamber 43, causing the vibration plate 44 to vibrate, thereby driving the arc push rod 45 to drive the bar magnet 48 into the driving coil 47 under the support plate 46. At this time, the magnetic flux changes, thereby generating current in the driving coil 47. After the controller 5 detects the generation of current in the driving coil 47, it controls the rotating motor 412 to start, driving the roller 410 to rotate, thereby causing the metal bristles 411 on the roller 410 to rotate accordingly, and contacting the grounded metal plate 415 forms an electric potential difference, and the metal bristles 411 continuously rub against the air during the rotation process, ionizing the air to produce ions, which neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller 410, it drives the long rod 413 to rotate, periodically pushing the dial plate 414 to swing, and pushing the surrounding air forward when the dial plate 414 is reset, thereby quickly pushing the generated ions to the surface of the goods, thereby improving the static electricity elimination rate of the fully loaded goods. In addition, when loading is completed, the staff can observe whether the roller 410 is rotating to determine the tightness of the cargo loading. When gaps appear in the loading, manual adjustments can be made, thereby improving loading efficiency and transportation space utilization, while avoiding damage to the goods caused by loading too loose or too tight.
