Description

Technical Field

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

[0002] At present, with the booming development of the logistics industry, the efficiency and quality of the goods loading and unloading link are directly related to the smooth operation of the entire logistics supply chain. Traditional logistics loading and unloading devices have many limitations in function and are difficult to meet the growing logistics needs, urgently requiring innovation and improvement.

[0003] Firstly, the loading angle of traditional logistics loading and unloading devices is single. When facing goods with different vehicle types, different placement positions, and different placement heights, the flexibility is seriously insufficient. At the same time, during the transportation of goods, due to vehicle bumps, improper handling operations, etc., the goods are prone to position deviation, tilt, etc. after loading. The existing logistics loading and unloading devices have limited ability in item correction, and most rely on manual secondary adjustment after loading, with low efficiency and poor results. Especially for some large and heavy goods, manual correction is extremely difficult.

[0004] Secondly, accurately mastering the loading tightness of goods is crucial for optimizing the utilization of transportation space and ensuring the safety of goods. At present, judging the loading tightness mainly relies on manual experience observation and simple measuring tools, which is highly subjective and inaccurate.

[0005] Finally, during the process of goods loading, especially when fully loaded, the friction between goods and the device, as well as between goods and goods, is extremely likely to generate static electricity. The accumulation of static electricity may cause a series of serious problems. For some flammable and explosive goods, static electricity discharge may trigger a fire or explosion, resulting in huge losses of life and property; for electronic goods, static electricity may damage electronic components and affect product quality. Summary of the Invention

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

[0007] To achieve the above purpose, the present invention provides the following technical solutions: A logistics loading and unloading device with multi-angle adjustment function includes a conveying frame, a conveying unit, a correction unit, a detection unit, and a controller. The conveying frame is placed on a horizontal foundation, 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 item correction, the detection unit is fixedly connected to the conveying frame, the detection unit has the functions of full-load goods determination and static electricity removal, and the controller is fixedly installed on the conveying frame.

[0008] The conveying rack is used to install and fix the conveying unit, the correction unit, the detection unit and the controller. The conveying unit is used for conveying articles. The correction unit is used for adjusting the attitude of tilted articles. The detection unit is used for detecting the tightness of loaded articles and eliminating static electricity. The controller is used to control the start and stop of the conveying unit, the correction unit and the detection unit. After the correction unit corrects the attitude of the article, it is clamped and placed on the conveying unit. The article is transported into the vehicle through the conveying unit. While the detection unit determines the tightness of the load according to the sound, it also removes the static electricity of the fully loaded goods, avoiding damage to the components of electronic goods and combustion and explosion caused by static electricity, and ensuring the integrity and safety of the goods.

[0009] Furthermore, the conveying unit includes a conveying motor, a conveyor belt, conveying rollers and a first electric telescopic rod. The fixed end of the conveying motor is fixedly installed on the conveying rack. The output end of the conveying motor is fixedly connected to one end of the conveying roller. The other end of the conveying roller is rotatably connected to the conveying rack. The conveyor belt is wrapped around the outer surface of the conveying roller. The fixed end of the first electric telescopic rod is fixedly installed on the conveying rack. The telescopic end of the first electric telescopic rod is fixedly connected to the rotating end of the conveying rack.

[0010] The controller controls the start of the conveying motor, thereby driving the conveying 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 articles neatly at different heights, the controller controls the first electric telescopic rod to extend and retract different lengths to adjust different angles, providing multi-angle placement of articles and improving flexibility.

[0011] Furthermore, the correction unit includes a second electric telescopic rod, a connecting plate, a semi-toothed plate, a gear, a pulling rope, a right-angle rod, a first electric telescopic plate and a second electric telescopic plate. The fixed end of the second electric telescopic rod is fixedly installed on the conveying rack. The output end of the second electric telescopic rod is fixedly connected to the connecting plate. One end of the connecting plate is rotatably connected to the conveying rack, 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 rack through a connecting round rod. The pulling rope is wound around the end of the connecting round rod connecting the gear and the conveying rack. The right-angle rod is fixedly connected to the fixed end of the second electric telescopic plate.

[0012] Further, the correction unit further includes a column, a winding rod, a protective plate, a driving motor, a clamping plate, a photoresistor, an air pump, an electromagnet, a buffer airbag and a sealing 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 round rod of the gear through a pull rope that bypasses the winding rod, the fixed end of the driving motor is fixedly installed at the telescopic end of the first electric telescopic plate, the output end of the driving motor is fixedly connected to the clamping plate, the photoresistor is fixedly installed at the end of the telescopic end of the first electric telescopic plate, the air pump is fixedly installed on the conveying frame, there are two air outlets on the air pump, the electromagnet is composed 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, 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 at one end of the clamping plate for clamping the goods, the buffer airbag is connected in a conducting manner to the air outlet of the air pump through a pipeline, the sealing cover is fixedly connected to one end of the right-angle rod, the sealing cover is slidably installed at the air outlet of the air pump, and the sealing cover is located inside the pipeline.

[0013] When the goods in the vehicle tilt due to the bumps during driving, the controller controls the driving motor to start. When the clamping plate rotates to both sides of the goods, the second electric telescopic rod starts at the same time, pushing the connecting plate to rotate upward around the conveying frame. During the process of righting the tilted goods, the semi-tooth plate drives the gear to rotate clockwise, so as to wind the pulling rope around the connecting round rod. As the pulling rope is wound, it pulls the protective plate to rotate around the column around the winding rod, so that the two protective plates approach each other. For small goods, the goods are pushed to the designated clamping position. For large goods, the blocking effect of the two protective plates prevents the situation of forward rollover caused by unstable center of gravity during the gradual correction of the tilted goods, further ensuring the safety of the goods. During the upward righting action of the clamping plate, since the pressure of the tilted goods on one side of the clamping plate is greater than that on the other side, the thin-film pressure sensor detects the pressure on both sides of the clamping plate and converts it into an electrical signal and transmits it to the controller. When the pressure on one side of the clamping plate is too large, the controller sends 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, under the transmission of the right-angle rod, the blocking cover moves upward, thereby increasing the flow rate of the air outlet of the air pump. The gas of the air pump is delivered to the buffer airbag of the clamping plate on the pressed side, providing sufficient buffer protection for the tilted goods to avoid direct contact between the clamping plate and the goods when correcting the goods and 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 detects strong light again, the controller controls the second electric telescopic rod to contract and at the same time controls the driving motor to clamp the goods. The first electric telescopic plate and the second electric telescopic plate contract a certain distance to clamp the goods on the conveyor belt for conveying.

[0014] Further, the detection unit includes an electric push rod, a sliding table, a resonance cavity, a vibrating piece, an arc-shaped push rod, a support plate, a driving coil and a bar magnet. The fixed end of the electric push rod is fixedly installed on the conveying frame, the output end of the electric push rod is fixedly connected with the sliding table, the sliding table is rotatably installed on the conveying frame, the resonance cavity is fixedly installed on the lower surface of the sliding table, the vibrating piece is vertically fixedly installed on the inner surface of the resonance cavity, the arc-shaped push rod is fixedly installed on the side surface of the vibrating piece, the support plate is fixedly installed on the inner wall of the resonance cavity, the driving coil is fixedly installed on the lower surface of the support plate, and the bar magnet is fixedly installed at the end of the arc-shaped push rod close to the support plate.

[0015] Furthermore, the detection unit further includes a straight plate, a roller, metal bristles, a rotating motor, a long rod, a dial plate and a grounded metal plate. One end of the straight plate is fixedly connected to the outer surface of the resonance cavity, and the other end is rotatably connected to the roller. Multiple groups of metal bristles are arranged on the outer surface of the roller. The fixed end of the rotating motor is fixedly installed on the straight plate, and the output end of the rotating motor is fixedly connected to the roller. The long rod is fixedly installed at the end of the roller away from the rotating motor. The dial plate is rotatably installed on the lower surface of the sliding table. The grounded metal plate is installed below the sliding table through a connecting rod, and the grounded metal plate is located below the roller.

[0016] When the goods are transported to the sliding table, the controller controls the electric push rod to contract a certain distance, slides the goods to the designated area and designated height in the vehicle, so as to realize multi-angle adaptive loading of goods. When the goods are loaded into the vehicle, the sounds produced are different. When the full-load frequency sound enters the resonance cavity, it prompts the vibrating piece to vibrate, thereby driving the arc-shaped push rod to drive the bar magnet into the drive coil below the support plate. At this time, the magnetic flux changes, and thus an electric current is generated in the drive coil. After the controller detects the generation of the current in the drive coil, it controls the rotating motor to start, driving the roller to rotate, so that the metal bristles on the roller rotate accordingly, forming an electric potential difference with the grounded metal plate. The metal bristles continuously rub against the air during rotation, ionizing the air to generate ions, and these ions neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller, the long rod is driven to rotate, periodically pushing the dial plate to swing. When the dial plate returns to its original position, it pushes the surrounding air forward, thereby quickly pushing the generated ions to the surface of the goods, improving the elimination rate of static electricity of the full-load goods. In addition, when the loading is completed, the staff can observe whether the roller rotates to determine the tightness of the goods loading. When there is a gap during loading, manual adjustment can be made, thereby improving the loading efficiency and the utilization rate of the transportation space, and at the same time avoiding damage to the goods caused by over-loose or over-tight loading.

[0017] Furthermore, a thin film pressure sensor is provided at the contact end of the buffer airbag and the clamping plate.

[0018] In order to detect the pressure on one side of the inclined goods, the lower electromagnet is controlled to drive the second electric telescopic plate to move upward, so that the plugging plate moves upward to increase the air pump flow rate, thereby adjusting the gas delivery volume of the buffer airbag on that side, providing sufficient buffer protection for the inclined goods, and avoiding direct contact between the clamping plate and the goods when correcting the goods, causing damage to the goods.

[0019] Furthermore, the tooth number ratio of the semi-tooth plate to the gear is in the range of 3:1 to 6:1.

[0020] When correcting tilted cargo, the rotation angle of the guard plate needs to be precisely controlled to ensure that the guard plate can effectively contact the cargo and apply appropriate correction force. When the ratio of the half-toothed plate to the gear is within this range, more precise rotation control can be achieved to ensure the accuracy of the correction action, avoiding poor correction effect due to excessive or small rotation range, or even secondary damage to the cargo.

[0021] Furthermore, the magnetism of the upper electromagnet is opposite to that of the lower electromagnet.

[0022] The receiving current of the upper electromagnet increases the magnetism and drives 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.

[0023] Furthermore, the conveying frame is provided with rollers.

[0024] 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.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. When the inclination angles at different heights need to be adjusted and the objects are neatly stacked at different heights, the controller controls the electric telescopic rod to extend and retract different lengths to adjust different angles, thereby providing multi-angle object 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.

[0026] 2. The present invention, when the cargo in the vehicle is tilted due to driving bumps, the second electric telescopic rod pushes the connecting plate to rotate from bottom to top around the conveying frame, driving the semi-toothed plate to drive the gear to rotate clockwise, and the winding rope drives the protective plates to approach each other, so as to push the small cargo to the designated clamping position. For large cargo, the blocking effect of the two protective plates can avoid the rollover in the front and rear directions caused by the unstable center of gravity during the correction process of the tilted cargo, thereby ensuring the safety of the cargo. During the straightening action process of the clamping plate from bottom to top, when the pressure of 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, so that the blocking cover moves 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, so as to provide sufficient buffer protection for the tilted cargo, and avoid direct contact between the clamping plate and the cargo when correcting the cargo, thereby causing damage to the cargo.

[0027] 3. In the present invention, when the sound of the frequency at full load of the goods enters the resonance cavity, the vibrating piece vibrates, driving the bar magnet on the arc-shaped push rod into the driving coil, changing the magnetic flux, generating an electric current in the driving coil. After the controller detects the generation of the current in the driving coil, it controls the rotating motor to drive the roller to rotate, so that the metal bristles on the roller rotate accordingly, forming an electric potential difference with the grounded metal plate. The metal bristles rub against the air, ionizing the air to generate ions, and these ions neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller, the long rod is driven to rotate, periodically pushing the dial to swing. When the dial resets, it pushes the surrounding air forward, thus quickly pushing the generated ions to the surface of the goods, improving the elimination rate of static electricity on the full-load goods.

[0028] 4. When the loading is completed, the staff can observe whether the roller rotates to determine the tightness of the goods loading. When there are gaps in the loading, manual adjustment can be made, thereby improving the loading efficiency and the utilization rate of the transportation space, and at the same time avoiding damage to the goods caused by over-loose or over-tight loading.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Embodiment: As Figures 1-8 shown, the present invention provides a technical solution: As Figure 1 shown, a logistics loading and unloading device with a multi-angle adjustment function includes a conveying rack 1, a conveying unit 2, a correction unit 3, a detection unit 4 and a controller 5. The conveying rack 1 is placed on a horizontal foundation. The conveying rack 1 is fixedly connected to the conveying unit 2. The correction unit 3 is fixedly installed on the conveying rack 1. The correction unit 3 has the function of item correction. The detection unit 4 is fixedly connected to the conveying rack 1. The detection unit 4 has the functions of full-load cargo determination and static elimination. The controller 5 is fixedly installed on the conveying rack 1.

[0033] The conveying rack 1 is used to install and fix the conveying unit 2, the rectifying unit 3, the detecting unit 4 and the controller 5. The conveying unit 2 is used for conveying articles. The rectifying unit 3 is used for adjusting the posture of tilted articles. The detecting unit 4 is used for detecting the tightness of loaded articles and eliminating static electricity. The controller 5 is used to control the start and stop of the conveying unit 2, the rectifying unit 3 and the detecting unit 4. After the rectifying unit 3 corrects the posture of the article, it is clamped and placed on the conveying unit 2, and the article is transported into the vehicle through the conveying unit 2. While the detecting unit 4 determines the tightness of the load according to the sound, it removes the static electricity of the fully loaded goods, avoiding damage to the components of electronic goods and combustion and explosion caused by static electricity, and ensuring the integrity and safety of the goods.

[0034] As Figure 2 , 4 shown, the conveying unit 2 includes a conveying motor 21, a conveyor belt 22, conveying rollers 23 and a first electric telescopic rod 24. The fixed end of the conveying motor 21 is fixedly installed on the conveying rack 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 rack 1. The conveyor belt 22 is wrapped around the outer surface of the conveying roller 23. The fixed end of the first electric telescopic rod 24 is fixedly installed on the conveying rack 1. The telescopic end of the first electric telescopic rod 24 is fixedly connected to the rotating end of the conveying rack 1.

[0035] 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 specified vehicle or area. When it is necessary to adjust the tilt angle at different heights and stack the articles neatly at different heights, the controller 5 controls the first electric telescopic rod 24 to extend and retract different lengths to adjust different angles, providing placement of articles at multiple angles and improving flexibility.

[0036] As Figure 4 shown, the rectifying unit 3 includes a second electric telescopic rod 31, a connecting plate 32, a semi-tooth plate 33, a gear 34, a pulling 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 second electric telescopic rod 31 is fixedly installed on the conveying rack 1. The output end of the second electric telescopic rod 31 is fixedly connected to the connecting plate 32. One end of the connecting plate 32 is rotatably connected to the conveying rack 1, and the other end is fixedly connected to the fixed end of the first electric telescopic plate 37. The semi-tooth plate 33 is fixedly installed on the connecting plate 32. The gear 34 is rotatably installed on the conveying rack 1 through a connecting round rod. The pulling rope 35 is wound around the end of the connecting round rod connecting the gear 34 and the conveying rack 1. The right-angle rod 36 is fixedly connected to the fixed end of the second electric telescopic plate 38.

[0037] As Figure 4 , 5As shown in the figure, the correction unit 3 further includes a vertical column 39, a winding rod 310, a protection plate 311, a driving motor 312, a clamping plate 313, a photoresistor 314, an air pump 315, an electromagnet 316, a buffer airbag 317 and a plugging cover 318. The vertical column 39 is slidably connected to the telescopic end of the second electric telescopic plate 38, and the vertical 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 protection plate 311 is rotatably connected to the vertical column 39. The protection plate 311 is connected to the connecting round rod of the gear 34 through a pull rope 35 that bypasses the winding rod 310. The fixed end of the driving motor 312 is fixedly installed at the telescopic end of the first electric telescopic plate 37, and the output end of the driving motor 312 is fixedly connected to the clamping plate 313. The photoresistor 314 is fixedly installed at the end of the telescopic end of the first electric telescopic plate 37. The air pump 315 is fixedly installed on the conveying rack 1, and there are two air outlets on the air pump 315. The electromagnet 316 is composed of an upper electromagnet 3161 and a lower electromagnet 3162. The upper electromagnet 3161 is fixedly installed on the lower surface of the fixed end of the first electric telescopic plate 37, and the lower electromagnet 3162 is fixedly installed on the upper surface of the fixed end of the second electric telescopic plate 38. The buffer airbag 317 is fixedly installed at one end of the clamping plate 313 for clamping the goods. The buffer airbag 317 is connected to the air outlet of the air pump 315 through a pipeline in a conducting manner. The plugging cover 318 is fixedly connected to one end of the right-angle rod 36, and the plugging cover 318 is slidably installed at the air outlet of the air pump 315. The plugging cover 318 is located inside the pipeline.

[0038] When the goods in the vehicle tilt due to the bumps during driving, the controller 5 controls the driving motor 312 to start. When the clamping plate 313 rotates to both sides of the goods, the second electric telescopic rod 31 starts at the same time, pushing the connecting plate 32 to rotate upward around the conveying frame 1. During the process of righting the tilted goods, the semi-tooth plate 33 drives the gear 34 to rotate clockwise, so as to wind the pulling rope 35 around the connecting round rod. As the pulling rope 35 is wound, it pulls the protective plate 311 to rotate around the column 39 around the winding rod 310, so that the two protective plates 311 approach each other. For small goods, the goods are pushed to the designated clamping position. For large goods, the blocking effect of the two protective plates 311 prevents the tilted goods from tipping forward due to unstable center of gravity during the gradual correction process, further ensuring the safety of the goods. During the upward righting action of the clamping plate 313, since the pressure of the tilted goods on one side of the clamping plate 313 is greater than that on the other side, the thin-film pressure sensor detects the pressure on both sides of the clamping plate 313 and converts it into an electrical signal and transmits it to the controller 5. When the pressure on one side of the clamping plate 313 is too large, the controller 5 sends 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, under the transmission action of the right-angle rod 36, the blocking cover 318 moves upward, thereby increasing the flow rate of the air outlet of the air pump 315. The gas of the air pump 315 is delivered to the buffer air bag 317 of the clamping plate 313 on the pressed side, providing sufficient buffer protection for the tilted goods 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 attitude correction of the goods is completed at this time. When the photoresistor 314 detects strong light again, the controller 5 controls the second electric telescopic rod 31 to contract and at the same time controls the driving motor 312 to clamp the goods. The first electric telescopic plate 37 and the second electric telescopic plate 38 contract a certain distance to clamp the goods on the conveyor belt 22 for conveying.

[0039] As Figure 3 , 6 , 7, and 8 show that the detection unit 4 includes an electric push rod 41, a sliding table 42, a resonance cavity 43, a vibrating piece 44, an arc-shaped push rod 45, a support plate 46, a driving coil 47, and a bar magnet 48. The fixed end of the electric push rod 41 is fixedly installed on the conveying frame 1, the output end of the electric push rod 41 is fixedly connected to the sliding table 42, the sliding table 42 is rotatably installed on the conveying frame 1, the resonance cavity 43 is fixedly installed on the lower surface of the sliding table 42, the vibrating piece 44 is vertically fixedly installed on the inner surface of the resonance cavity 43, the arc-shaped push rod 45 is fixedly installed on the side surface of the vibrating piece 44, the support plate 46 is fixedly installed on the inner wall of the resonance cavity 43, the driving coil 47 is fixedly installed on the lower surface of the support plate 46, and the bar magnet 48 is fixedly installed at the end of the arc-shaped push rod 45 close to the support plate 46.

[0040] AsFigure 3 , 6 As shown in Fig. 7, the detection unit 4 further includes a straight plate 49, a roller 410, metal bristles 411, a rotary motor 412, a long rod 413, a dial plate 414 and a grounded metal plate 415. One end of the straight plate 49 is fixedly connected to the outer surface of the resonance cavity 43, and the other end is rotatably connected to the roller 410. A plurality of groups of metal bristles 411 are arranged on the outer surface of the roller 410. The fixed end of the rotary motor 412 is fixedly installed on the straight plate 49, and the output end of the rotary motor 412 is fixedly connected to the roller 410. The long rod 413 is fixedly installed at one end of the roller 410 away from the rotary motor 412. The dial plate 414 is rotatably installed on the lower surface of the slide 42. The grounded metal plate 415 is installed below the slide 42 through a connecting rod, and the grounded metal plate 415 is located below the roller 410.

[0041] When the goods are transported onto the slide 42, the controller 5 controls the electric push rod 41 to contract a certain distance, slides the goods to the designated area and the designated height in the vehicle, so as to realize multi-angle adaptive loading of the goods. When the goods are loaded into the vehicle, the sounds generated are different. When the sound of the full-load frequency enters the resonance cavity 43, it causes the vibrating piece 44 to vibrate, thereby driving the arc-shaped push rod 45 to drive the bar magnet 48 into the drive coil 47 below the support plate 46. At this time, the magnetic flux changes, thereby generating an electric current in the drive coil 47. After the controller 5 detects the generation of the current in the drive coil 47, it controls the rotary motor 412 to start, driving the roller 410 to rotate, so that the metal bristles 411 on the roller 410 rotate accordingly, forming a potential difference with the grounded metal plate 415. The metal bristles 411 continuously rub against the air during rotation, ionizing the air to generate ions, and these ions neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller 410, the long rod 413 is driven to rotate, periodically pushing the dial plate 414 to swing. When the dial plate 414 returns to its original position, it pushes the surrounding air forward, thereby quickly pushing the generated ions onto the surface of the goods, improving the elimination rate of static electricity of the full-load goods. In addition, when the loading is completed, the staff can observe whether the roller 410 rotates to determine the tightness of the goods loading. When there is a gap during loading, manual adjustment can be made, thereby improving the loading efficiency and the utilization rate of the transportation space, and at the same time avoiding damage to the goods caused by over-loose or over-tight loading.

[0042] As Figure 5 shown, a thin film pressure sensor is provided at the contact end of the buffer airbag 317 and the clamping plate 313.

[0043] In order to detect the pressure on one side of the tilted goods, the lower electromagnet 3162 is controlled to drive the second electric telescopic plate 38 to move upward, so that the blocking plate moves upward to increase the flow rate of the air pump 315, thereby adjusting the gas delivery volume of the buffer airbag 317 on this side, providing sufficient buffer protection for the tilted goods, and avoiding direct contact between the clamping plate 313 and the goods when correcting the goods, causing damage to the goods.

[0044] As Figure 4 shown, the tooth number ratio of the semi-tooth plate 33 to the gear 34 is in the range of 3:1 to 6:1.

[0045] When correcting the tilted goods, it is necessary to accurately control the rotation angle of the protection plate 311 to ensure that the protection plate 311 can effectively contact the goods and apply an appropriate corrective force. When the tooth number ratio of the semi-tooth plate 33 to the gear 34 is within this range, relatively fine rotation control can be achieved, ensuring the accuracy of the corrective action and avoiding poor corrective effects or even secondary damage to the goods caused by too large or too small rotation amplitude.

[0046] As Figure 5 shown, the magnetism of the upper electromagnet 3161 is opposite to that of the lower electromagnet 3162.

[0047] When the received current of the upper electromagnet 3161 increases its magnetism, it drives the lower electromagnet 3162 to move upward, thereby changing the area of the air outlet blocked by the blocking cover 318, enabling the buffer airbag 317 on the clamping plate 313 on the side with greater pressure to provide sufficient gas, so as to buffer the pressure of the goods on the clamping plate 313 and avoid damage to the goods during the correction process and destroy the integrity of the goods.

[0048] As Figure 1 shown, rollers are provided on the conveying rack 1.

[0049] The rollers enable the conveying rack 1 to move easily on various ground surfaces without manual handling or dragging, greatly reducing the physical burden. In occasions where the boxes need to be moved frequently, the rollers can significantly improve the moving efficiency.

[0050] The working principle of the present invention: The controller 5 controls the conveying motor 21 to start, thereby driving the conveying roller 23 to rotate, transporting the goods located on the conveyor belt 22 to a designated vehicle or area. When it is necessary to adjust the tilt angle at different heights and stack the items neatly at different heights, 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.

[0051] When the goods in the vehicle are tilted due to the bumps during driving, the controller 5 controls the driving motor 312 to start. When the clamping plate 313 is driven to rotate to both sides of the goods, the second electric telescopic rod 31 starts at the same time, pushing the connecting plate 32 to rotate upward around the conveying frame 1. During the process of righting the tilted goods, the semi-tooth plate 33 drives the gear 34 to rotate clockwise, thereby winding the pulling rope 35 around the connecting round rod. As the pulling rope 35 is wound, it pulls the protective plate 311 to rotate around the column 39 around the winding rod 310, so that the two protective plates 311 approach each other. For small goods, the goods are pushed to the designated clamping position. For large goods, the blocking effect of the two protective plates 311 prevents the situation of forward rollover caused by unstable center of gravity during the gradual correction of the tilted goods, further ensuring the safety of the goods. During the upward righting action of the clamping plate 313, since the pressure of the tilted goods on one side of the clamping plate 313 is greater than that on the other side, the thin film pressure sensor detects the pressures on both sides of the clamping plate 313 and converts them into electrical signals and transmits them to the controller 5. When the pressure on one side of the clamping plate 313 is too high, the controller 5 sends 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, under the transmission action of the right-angle rod 36, the plugging cover 318 moves upward, thereby increasing the flow rate of the air outlet of the air pump 315. The gas of the air pump 315 is delivered to the buffer airbag 317 of the clamping plate 313 on the pressed side, providing sufficient buffer protection for the tilted goods to avoid direct contact between the clamping plate 313 and the goods during the correction of the goods and causing damage to the goods. When the first electric telescopic plate 37 moves to the upper end of the goods, the attitude correction of the goods is completed at this time. When the photoresistor 314 detects strong light again, the controller 5 controls the second electric telescopic rod 31 to contract and at the same time controls the driving motor 312 to clamp the goods. The first electric telescopic plate 37 and the second electric telescopic plate 38 contract a certain distance to clamp the goods on the conveyor belt 22 for conveying.

[0052] When the goods are transported onto the sliding table 42, the controller 5 controls the electric push rod 41 to contract a certain distance, sliding the goods to the designated area and designated height inside the vehicle, so as to achieve multi-angle adaptive loading of the goods. When the goods are loaded into the vehicle, the sounds produced are different. When the frequency of the sound at full load enters the resonance cavity 43, it causes the vibrating piece 44 to vibrate, thereby driving the arc-shaped push rod 45 to drive the bar magnet 48 into the drive coil 47 below the support plate 46. At this time, the magnetic flux changes, generating an electric current in the drive coil 47. After the controller 5 detects the generation of the electric current in the drive coil 47, it controls the rotation motor 412 to start, driving the roller 410 to rotate. As a result, the metal bristles 411 on the roller 410 rotate accordingly, forming an electric potential difference with the grounded metal plate 415. During the rotation process, the metal bristles 411 continuously rub against the air, ionizing the air to generate ions. These ions neutralize the static electricity on the surface of the goods, thereby eliminating static electricity. During the rotation of the roller 410, the long rod 413 is driven to rotate, periodically pushing the dial 414 to swing. When the dial 414 resets, it pushes the surrounding air forward, quickly pushing the generated ions onto the surface of the goods, improving the elimination rate of static electricity of the fully loaded goods. In addition, when the loading is completed, the staff can observe whether the roller 410 rotates to determine the tightness of the goods loading. When there are gaps during loading, manual adjustment can be made, thereby improving the loading efficiency and the utilization rate of the transportation space, and at the same time avoiding damage to the goods caused by over-loose or over-tight loading.
