Description

Technical Field

[0001] The present invention belongs to the technical field of transmission devices for freight or transportation, and particularly relates to a transportation device for supply chain management logistics transportation. Background Art

[0002] A transportation device for supply chain management logistics transportation is a device that automatically transports a cargo box to a corresponding layer area of a corresponding shelf in a warehouse. It can realize the automatic handling of goods from the storage area to the shelf, reduce manual intervention, and improve logistics efficiency and warehouse space utilization rate.

[0003] Currently, there are already various types of transportation devices in the field of supply chain management logistics transportation. Some devices have achieved the automation and simplicity of equipment operation through designs such as a stabilizing mechanism, an adsorbing component, and a synchronizing component, reducing the use and maintenance of electric control components. There are also devices with an adjustable conveying angle to meet the conveying requirements of goods at different heights. In addition, some transportation devices can adjust their positions according to the size of an object by setting a placing table, an extension plate, a limiting plate, etc., improving applicability, and facilitating the transfer of the object through a limiting structure.

[0004] In the prior art, although there are transportation devices with various functions and designs, there are still some problems and deficiencies. For example, some devices are not convenient enough when placing goods on or taking goods off a placing board on a shelf. Staff cooperation is required to achieve automatic loading and unloading. Especially for heavy goods, the loading and unloading process is laborious and the degree of automation is low. In addition, most of the conveyor devices for supply chain management logistics transportation on the existing market have a fixed-height conveyor structure and cannot adjust their conveying angles, which is not conducive to use. At the same time, although some AGV cars can move a cargo box to a corresponding shelf position, they usually cannot directly push the cargo box deep into the corresponding layer area. Although some AGV intelligent cars carry a robotic arm and can move the cargo box, the robotic arm is relatively bulky and the operation efficiency is low.

[0005] In view of the above problems and deficiencies, it is necessary to improve the transportation device for supply chain management logistics transportation. Summary of the Invention

Install a position sensor or proximity switch at the installation position of the concave area of the belt machine main body, which can monitor the position information of the cargo box in real time and feedback the signal to the controller. When the cargo box reaches the front end of the conveyor belt, the position sensor triggers the subsequent flipping and pushing action, realizing the automation and precise control of the conveying process.

[0019] Enhance pushing accuracy

[0020] 4. Precise pushing of the flipping and pushing mechanism: The flipping and pushing mechanism can precisely push the cargo box to the inner side of the corresponding layer area of the shelf through the coordinated actions of components such as the flipping frame, the folding torsion member, the swing pushing assembly, and the flipping drive mechanism, ensuring the stability of the cargo box and the shelf.

The conveyor belt 33 is sleeved outside the belt guide wheels 36 at the front and rear ends, and the conveyor belt 33 is sleeved at the bottom of the pressure belt wheel 37 in the recessed area. A position sensor or a proximity switch is installed on one side or both sides of the belt machine main body 32 where the recessed area is located.

[0035] As Figure 6 As shown, the Z-shaped support 4 includes a fixed vertical plate 41, a web plate 42, side vertical plates 43, adjustment holes 44, and fixing bolts 45. The fixed vertical plate 41 is fixed to the lower part inside the web plate 42 (near the belt side), and the side vertical plates 43 are fixed to the upper part outside the web plate 42. A plurality of horizontal adjustment holes 44 are provided on the fixed vertical plate 41, and fixing bolts 45 are installed in each adjustment hole 44 of the fixed vertical plate 41. The fixing bolts 45 are fixed together with the side wall of the belt machine main body 32. After loosening the fixing bolts 45, the front and rear distance of the fixed vertical plate 41 can be adjusted. When the fixing bolts 45 are fixed, the entire fixed vertical plate 41 can be kept fixed at a suitable position on the front side of the belt machine main body 32.

[0036] As Figure 6As shown in the figure, the flipping frame 5 includes a fixed frame 51, a rear seat 52, a flipping column 53, a transverse rotating shaft 54, a shaft hole 55, a limit set screw 56 and a guide rod 57. The fixed frame 51 is fixed to the top of the side vertical plate 43. The rear seat 52 is fixed to the rear end of the fixed frame 51. Shaft holes 55 are respectively arranged on the side wall of the fixed frame 51 and the inner end of the rear seat 52. The bottom of the flipping column 53 is horizontally fixed with a transverse rotating shaft 54. The two ends of the transverse rotating shaft 54 are correspondingly sleeved in the respective shaft holes 55 and can rotate. A guide rod 57 is fixed on the upper side of the flipping column 53. A limit set screw 56 is threadedly installed on the front end face of the rear seat 52, and the limit set screw 56 can be adjusted to extend or retract.

[0037] As Figure 6 shown in the figure, the folding and twisting member 6 includes a support block 61, a longitudinal shaft hole 62, a longitudinal rotating block 63, a universal joint 64, a rear folding rod 65, a front folding rod 66, an extreme baffle 67 and an extreme stop block 68. A support block 61 is fixed to the rear side of the fixed frame 51. The support block 61 is provided with a longitudinal shaft hole 62 along the longitudinal direction. The longitudinal rotating block 63 includes a connecting block. A wire is installed along the longitudinal direction at the rear end of the connecting block, and there is a cap portion at the rear end of the wire. The rod body portion of the wire is sleeved in the longitudinal shaft hole 62. The connecting block is located on the front side of the support block 61, and the cap portion is located on the rear side of the support block 61. The front end of the support block of the longitudinal rotating block 63 is hinged to the rear end of the rear folding rod 65 through a universal joint 64, and the front end of the rear folding rod 65 is hinged to the rear end of the front folding rod 66. An extreme baffle 67 is fixed to the bottom of the front end of the rear folding rod 65. When the rear folding rod 65 and the front folding rod 66 are in a stretched parallel state, the extreme baffle 67 can support on the bottom of the front folding rod 66 to prevent the two from over-flipping. An extreme stop block 68 is fixed to the outside of the front folding rod 66. When the rear folding rod 65 and the front folding rod 66 are in a compressed folding state, the extreme stop block 68 can support on the top of the rear folding rod 65 to prevent the two from over-compressing. The extreme stop block 68 includes a screw sleeve and a positioning bolt. The screw sleeve is located on the outside of the front folding rod 66, and the positioning bolt is installed in the screw sleeve. The outside of the positioning bolt cap portion can support on the top surface of the rear folding rod 65.

[0038] As Figure 6 shown in the figure, the swing and push assembly 7 includes a rotating sleeve 71, a first shaft seat 72, a pin shaft 73, a second shaft seat 74, a suspension rod 75, a rotating roller 76 and a retaining nut 77. A rotating sleeve 71 is sleeved on the outer top of the guide rod 57. A protruding first shaft seat 72 is arranged on the rear side of the rotating sleeve 71, and a protruding second shaft seat 74 is arranged on the near belt side. The first shaft seat 72 is provided with a horizontal shaft hole and sleeved with a pin shaft 73, and the pin shaft 73 is hinged to the front end of the front folding rod 66. The second shaft seat 74 is provided with a longitudinal shaft hole and sleeved with a suspension rod 75, and a rotatable rotating roller 76 is sleeved on the outside of the suspension rod 75.

[0039] As Figure 6As shown, the flipping drive mechanism 8 includes a fixed hinge seat 81, a flipping push rod 82, a sleeve 83, a moving hinge seat 84, a lower spherical joint 85, and an upper spherical joint 86. The fixed hinge seat 81 is fixed on the upper side or rear side of the rear seat 52. A sleeve 83 is sleeved outside the guide rod 57, and the moving hinge seat 84 is fixed on the front side of the top of the sleeve 83. The bottom of the flipping push rod 82 is hinged to the fixed hinge seat 81 through the lower spherical joint 85, and the top is hinged to the moving hinge seat 84 through the upper spherical joint 86. The controller can control the extending or retracting action of the flipping push rod 82.

[0040] Figure 3 and Figure 4 It shows that flipping propulsion mechanisms are respectively installed on the left and right sides at the front end of the conveyor belt machine 3, and the two-sided flipping propulsion mechanisms are symmetrically distributed. By adjusting the left and right fixing bolts 45, it can be adjusted to ensure that the left and right flipping propulsion mechanisms are slightly misaligned; at the same time, by respectively adjusting the limit set screws 56 at the front end of each flipping propulsion mechanism, the limit set screws 56 at the front ends of the left and right flipping propulsion mechanisms are kept flush.

[0041] Thus, when the AGV intelligent vehicle 1 drives the lifting frame 2 and the conveyor belt machine 3 to fit against the outer wall of the corresponding shelf layer area, the end faces of the left and right limit set screws 56 can be kept in butt joint with the outer wall of the shelf. Since the belt body 32 of the conveyor belt machine 3 is only located outside the shelf layer area, the cargo box can only be conveyed to the outer edge area of the shelf layer area and cannot completely enter the inner side of the corresponding shelf layer area. Based on the above solution, it is necessary to rely on the left and right flipping propulsion mechanisms to push the cargo box forward continuously and enter the inner side of the corresponding shelf layer area to ensure the stability of the cargo box and the shelf, as Figure 4 shown.

[0042] When the above solution works, when the AGV intelligent vehicle 1 transfers the cargo box to the position below the corresponding shelf, the controller controls the lifting frame 2 to lift, so that the conveyor belt machine 3 approaches the bottom position of the corresponding layer area. The belt body 32 of the conveyor belt machine 3 drives the cargo box to move forward. When the conveyor belt machine 3 transfers the cargo box to the front end, the belt body 32 rotates and cannot push the cargo box to move forward continuously. At this time, most of the cargo box has been pushed into the corresponding shelf layer area. Then the controller controls the flipping push rod 82 to start the retracting action, completing the process of (1)-(3) in Figure 4 and Figure 7 . Push the cargo box forward continuously and enter the inner side of the corresponding shelf layer area to ensure the safety of the cargo box. Figure 7 Only the structural schematic diagram of a set of flipping propulsion mechanisms on the right side is shown.

[0043] Specifically, as shown in (1) of Figure 4 and Figure 7 , when the flipping push rod 82 is in the extended state, it can flip the flipping frame 5 backward. After flipping, the roller 76 is in a horizontal state and is hidden above the recessed area.Figure 5 As shown in the figure, two offset rotating rollers 76 are respectively located above the pressure belt wheel 37 and in contact with the upper side of the pressure belt wheel 37. At this time, the folding torsion member 6 is in a compressed state, and the pin shaft 73 is in an upright state. When the conveyor belt 33 moves forward, it can drive the pressure belt wheel 37 to rotate counterclockwise. The counterclockwise rotation of the pressure belt wheel 37 can drive the two upper rotating rollers 76 to rotate clockwise respectively. The cargo box moves forward along the rear side of the concave area of the conveyor belt 33. After passing through the two rotating rollers 76 on the upper side of the concave area, it continues to move forward on the front side of the concave area.

[0044] As Figure 4 and Figure 7 shown in (2) of the figure, when the cargo box is conveyed forward and passes through the concave area, the position sensor sends a signal to the controller. The controller controls the flipping push rod 82 to be in a continuous telescoping process. The flipping frame 5 flips upward and drives the folding torsion member 6 to start gradually unfolding. When the folding torsion member 6 is driven to unfold, it can pull the swing push assembly 7 to rotate (the right set of flipping propulsion mechanisms rotates clockwise, and the left set of flipping propulsion mechanisms rotates counterclockwise). Furthermore, it drives the two rotating rollers 76 on both sides to gradually lift upward from the initial horizontal state. The continuously lifted rotating rollers 76 on both sides can push the cargo box forward continuously from the rear side of the cargo box.

[0045] As Figure 4 and Figure 7 shown in (3) of the figure, when the flipping push rod 82 contracts to the limit position, the flipping frame 5 is pulled up to an upright state. At this time, the folding torsion member 6 is straightened. The folding torsion member 6 can pull the swing push assembly 7 to rotate so that the pin shaft 73 is in a nearly horizontal state, and the rotating roller 76 is in the maximum limit position of forward pushing. At this time, the cargo box can be pushed to the inner side of the corresponding layer area of the shelf.

[0046] The structures of the flipping propulsion mechanism in the unfolded and folded states are as Figure 8 and Figure 9 shown.

[0047] Figure 10The middle controller establishes a connection with the background server through the wireless communication module, receives transportation instructions, checks whether each sensor and actuator are working properly, and the controller controls the AGV intelligent vehicle to move to the position where the cargo box is located according to the transportation instructions. The AGV intelligent vehicle transports the cargo box to the position below the target shelf. The controller controls the lifting push rod of the lifting frame to lift the cargo box to the height of the target shelf layer area, and controls the rotation drive mechanism of the conveyor belt machine to convey the cargo box to the front end of the conveyor belt machine. The position sensor detects that the cargo box has reached the front end of the conveyor belt machine and sends a signal to the controller. The controller controls the flipping push rod of the flipping and pushing mechanism to start the flipping and pushing action and push the cargo box to the inside of the shelf. After the cargo box is successfully stored in the warehouse, the controller issues a reset instruction, and each component returns to the initial state, and the device remains in a standby state, waiting for the next transportation task. It can achieve efficient and precise control of the transportation device for logistics transportation, ensuring the automated transportation and warehousing process of the cargo box.

[0048] Among them, the controller of the control system serves as the control core of the entire system, responsible for receiving and parsing the transportation instructions of the background server, as well as processing the feedback signals from each sensor. The wireless communication module realizes the wireless communication between the controller and the background server, receives the transportation instructions and feedbacks the working status of the device. The position sensor / proximity switch is installed in the recessed area of the conveyor belt machine to monitor the position information of the cargo box in real time. When the cargo box reaches the specified position, it sends a signal to the controller. The AGV intelligent vehicle control is connected to the controller, receives the movement command of the controller, and controls the drive motor of the AGV intelligent vehicle to realize the handling and transportation of the cargo box. The lifting frame control is connected to the controller, receives the lifting instruction of the controller, and controls the lifting push rod of the lifting frame to realize the lifting and lowering of the cargo box. The conveyor belt machine control is connected to the controller, receives the conveying instruction of the controller, and controls the rotation drive mechanism of the conveyor belt machine to realize the conveying of the cargo box. The flipping and pushing mechanism control is connected to the controller, receives the pushing instruction of the controller, and controls the flipping push rod of the flipping and pushing mechanism to realize the pushing of the cargo box into the warehouse.

[0049] When the above-mentioned transportation device for logistics transportation is in use, first, connect the power supply of the device, start the controller, and establish a connection with the background server through the wireless communication module. Check whether each component such as the AGV intelligent vehicle, the lifting frame, the conveyor belt machine, and the flipping and pushing mechanism is in a normal state to ensure the normal operation of the device. Task reception and instruction parsing: The background server sends a transportation instruction to the device through the wireless communication module, and the controller parses the instruction to clarify task details such as the position of the target shelf, the height of the layer area, and the information of the cargo box, so as to prepare for subsequent operations. The AGV intelligent vehicle navigates autonomously along the preset path to the position where the cargo box is located according to the instruction of the controller, and uses its back-mounted structure to carry the cargo box to achieve the efficient transfer of the cargo box between different areas. When the AGV intelligent vehicle transports the cargo box to the position below the target shelf, the controller starts the lifting push rod of the lifting frame, drives the scissor frame to unfold, and smoothly lifts the cargo box to a height matching the bottom of the target shelf layer area. When the cargo box is transported to the front end of the conveyor belt machine, the position sensor detects its arrival, and the controller starts the flipping and pushing mechanism. The flipping push rod begins to contract, driving the flipping frame to rotate around the horizontal rotation shaft, and then through the linkage of the folding torsion member and the swing pushing component, the roller gradually flips from the hidden state to the pushing position. Pushing the cargo box into the inner side of the shelf: During the flipping process of the roller of the flipping and pushing mechanism, it pushes the cargo box from the rear side of the cargo box, so that it continues to move forward and deep into the inner side of the shelf layer area. During this process, the flipping and pushing mechanisms on both the left and right sides work together to ensure that the cargo box is smoothly and accurately pushed to the designated position on the shelf to complete the warehousing operation. After the cargo box is successfully warehoused, the controller issues a reset instruction. The lifting push rod of the lifting frame contracts, and the scissor frame retracts into the storage bin; the conveyor belt machine stops running and returns to the initial state; the flipping push rod of the flipping and pushing mechanism extends, so that the flipping frame, the folding torsion member, the swing pushing component, etc. return to their original positions. After the device is reset, it remains in a standby state, ready to receive and execute the next transportation task at any time, realizing the continuity and efficiency of logistics transportation.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
