Description

Technical Field

[0001] The present invention relates to the technical field of warehousing and conveying equipment, and in particular to an intelligent transportation device for logistics warehousing. Background Art

[0002] Logistics warehousing refers to a series of activities such as warehousing, storage, custody, and outbound delivery of goods using warehouses and related facilities and equipment. It is not only a place for goods storage, but also an important node for the circulation of goods in the logistics supply chain. Warehousing can be divided into custody warehousing and circulation warehousing according to its function. Compared with custody warehousing, the circulation warehousing used by e-commerce supporting manufacturers has a fast turnover rate and can support the rapid circulation of goods.

[0003] Considering that logistics warehousing requires a lot of manpower for cargo handling and management, in order to reduce dependence on labor and thus reduce labor costs, most of the circulation warehousing used by e-commerce supporting manufacturers uses intelligent transportation equipment for cargo handling and management. Intelligent transportation equipment can accurately control the storage and handling of goods, reduce space waste, improve the utilization rate of storage facilities, effectively reduce labor costs, and thus improve the economy of logistics warehousing.

[0004] At present, when the intelligent transport equipment used in circulation warehousing is transporting tissues packed in cartons, since several layers of cartons need to be loaded at a time, the center of gravity of the tissues and cartons is located above the intelligent transport equipment. When the intelligent transport equipment moves in the logistics warehousing, it is inevitable to perform turning operations. When the carton goods reach a certain height, they are very likely to fall from the outer edge of the turn of the intelligent transport equipment under the action of centrifugal force. In order to prevent the carton goods from falling when the intelligent transport equipment turns, the existing technology often uses plastic film wrapped around the outside of the carton goods for simple binding, or greatly reduces the turning speed when the intelligent equipment turns. The above operations will cause low efficiency in the handling of carton goods, resulting in limited economic efficiency of logistics warehousing.

[0005] To this end, an intelligent transportation device for logistics warehousing is proposed. Summary of the invention

[0006] The object of the present invention is to provide an intelligent transportation device for logistics warehousing, which provides lateral protection for carton goods by activating the side stop assembly located outside the turning radius when turning, and can block the forward movement of goods from the front side of the goods in case of emergency braking. This solves the problem that existing intelligent transportation equipment needs to wrap plastic film around the carton goods or greatly reduce the turning speed, which causes low efficiency of the intelligent transportation equipment when transferring carton goods and has an adverse effect on the economy of logistics warehousing. It has the advantages of no need for additional binding of carton goods, and effectively improving the speed of intelligent transportation equipment when turning, and does not affect the later handling of goods, effectively improving the handling efficiency of goods, and improving the economy of logistics warehousing.

[0007] To achieve the above object, the present invention provides the following technical solutions: An intelligent transportation device for logistics warehousing, including a loading board, a limiting through groove, driving wheels, intelligent detection sensors, steering wheels, a control host, and reinforcing bars, further including a front baffle assembly, a support board, a side baffle assembly, a steering assembly, and a movable connection assembly. The two support boards are arranged in parallel below the loading board. The movable connection assembly is installed between the support board and the loading board. The front baffle assembly and the steering assembly are both installed between the side walls of the two support boards, and the top of the front baffle assembly extends into the limiting through groove. The side baffle assembly is installed on the surface of the loading board. The control host is respectively connected to the intelligent detection sensors, the side baffle assembly, and the steering assembly. When the steering assembly works, the control host turns on the power supply of the side baffle assembly located outside the turning radius. When the driving wheels make an emergency brake, the loading board drives the movable connection assembly to move forward. When the movable connection assembly moves forward to a set distance, it pushes the front baffle assembly to move upward.

[0008] In the above solution, when storing paper towel goods packed in cartons, to improve the transfer efficiency, 4 - 5 layers of cartons are stacked on the intelligent transportation device at a time. The height of a single - layer carton is about 30 cm. Therefore, the center of gravity of the stacked paper - towel - packed goods is about 60 - 80 cm. When turning, the turning speed of the intelligent transportation device should be controlled within the range of 3.6 - 5.4 kilometers per hour. Thus, it can be seen that the turning speed of the intelligent transportation device is greatly restricted, resulting in the limitation of the transportation efficiency of the intelligent transportation device. If this turning - speed limit is exceeded, it is necessary to use plastic film to temporarily bind the carton goods. This will not only increase the cost of intelligent transportation, but also when taking out a single carton of paper towels separately later, it is necessary to tear off the plastic film, which is particularly inconvenient during e - commerce shipping. Therefore, both will lead to a reduction in the economy of logistics warehousing. For this reason, in this technical solution, when the warehousing conveying device turns, the X - shaped frame in the side baffle assembly located outside the turning radius is correspondingly unfolded to provide support for the carton goods from the outside of the turning radius, and the X - shaped frame can be quickly retracted after the turning is completed. This not only does not require additional use of plastic film to bind the carton goods, simplifies the transportation process, but also can effectively increase the turning speed of the intelligent transportation device, and will not interfere with taking down the carton goods from the intelligent transportation device, greatly improving the transportation efficiency of this intelligent transportation device applied in fluid logistics warehousing, and will not increase additional costs, which is beneficial to greatly improving the economy of logistics warehousing.

[0009] Preferably, the movable connection assembly includes a chute, an elastic rod, and a mounting block. The chute is formed between the surface and the side wall of the support board. The mounting block is slidably arranged in the chute. The elastic rod is arranged in the chute, and the end of the elastic rod is connected to the mounting block.

[0010] Preferably, the movable connection assembly close to the driving wheel side also includes a side bar and a second wedge block, the side bar is installed on the side wall of the mounting block, and the side bar is arranged between two support plates, and the second wedge block is installed at the end of the side bar close to the driving wheel side.

[0011] Preferably, the front block assembly includes a connecting frame, a limit block and a lifting structure, the connecting frame is installed between two support plates, the two limit blocks are respectively slidably set in the limit grooves, and the limit blocks are installed at the end of the connecting frame, the lifting structure is overlapped on the connecting frame, and the lifting structure extends to the bottom of the connecting frame.

[0012] Preferably, the lifting structure includes a top plate, a through frame and a first wedge block, the top plate is overlapped on the surface of the connecting frame, the through frame is installed at the bottom of the top plate, and the through frame is slidably connected to the connecting frame, the first wedge block is integrally formed at the bottom of the through frame, and the inclined surfaces of the first wedge block and the second wedge block are both constructed on adjacent sides.

[0013] Preferably, the steering assembly includes a reinforcement frame, a steering gear, a connecting rod and a rotating plate, the reinforcement frame is installed between the side walls of two support plates, the steering gear is installed on the surface of the reinforcement frame, the rotating plate is rotatably connected to the end of the support plate away from the driving wheel, the connecting rod is rotatably installed between the two rotating plates, and the connecting rod is connected to the steering gear through a connecting strip.

[0014] Preferably, an arc-shaped portion is configured in the middle portion of the connecting rod, and the steering gear is located at the center of the arc-shaped portion.

[0015] Preferably, the side stop assembly comprises a vertical frame, an electric push rod, a connecting block and an X-shaped frame, the vertical frame is installed and connected to the loading plate, and the top of the vertical frame is flush with the top of the loading plate, the vertical frame is located on the side away from the two support plates, the electric push rod is installed on the inner bottom surface of the vertical frame, the connecting blocks are slidably arranged on both sides of the electric push rod, and the connecting blocks on one side are connected to the electric push rod, and the X-shaped frame is rotatably installed between the tops of the connecting blocks.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention needs to make multiple turns in the circulation logistics warehousing to transport the carton goods to the corresponding location, the side guard assembly located outside the turning radius can be unfolded accordingly during the turning process, thereby providing side guard support for the goods from the outside of the turning radius, thereby preventing the carton goods from falling from the edge of the intelligent transportation equipment under the action of centrifugal force, and at the same time, it can also greatly improve the speed range during the turn, thereby effectively improving the transportation efficiency of the intelligent transportation equipment and the economy of the circulation logistics warehousing.

[0017] 2. With the side baffle assembly, steering assembly, and control host set, when the intelligent transportation device turns, when the control component controls the steering gear to rotate in the corresponding direction, the control host simultaneously turns on the power supply of the side baffle assembly located outside the turning radius and controls the electric push rod to contract to deploy the X-shaped frame. The height of the deployed X-shaped frame is increased, forming a mesh protection structure outside the turning radius of the carton goods, preventing the carton goods from falling from the edge of the intelligent transportation device under the action of centrifugal force. At the same time, after the turning is completed, the control host quickly resets the electric push rod to retract the X-shaped frame. When the carton goods are transferred to the corresponding location, the movement of the goods will not be affected by the X-shaped frame, thereby effectively ensuring the transportation efficiency of the intelligent transportation device.

[0018] 3. With the lifting structure and movable connection assembly set, when the intelligent transportation device needs to stop, due to the relatively smooth contact surface between the carton and the intelligent transportation device, under the action of inertia, even if only the surface of the intelligent transportation device is roughened, the carton goods are still likely to tilt forward and fall from the surface of the intelligent transportation device. Therefore, when the intelligent transportation device stops, by utilizing the inertia of the carton goods to move forward to lift the through-frame in the lifting structure, not only can the carton goods be effectively prevented from falling from the front side of the intelligent transportation device, but also the absolute value of the acceleration during deceleration can be further increased. As a result, the intelligent transportation device can stop within a shorter time or transport the carton goods at a higher speed, also effectively improving the transportation efficiency of the carton goods.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 The present invention provides an intelligent transportation device for logistics warehousing, and the technical solution is as follows: Reference Figure 1 and Figure 2, an intelligent transportation device for logistics warehousing, comprising a loading plate 1, a limit slot 2, a driving wheel 4, an intelligent detection sensor 6, a steering wheel 8, a control host 10, and a reinforcement strip 11. The surface of the loading plate 1 is roughened, the limit slot 2 is opened at the front end of the surface of the loading plate 1, the intelligent detection sensor 6 is installed at the bottom of the front end of the loading plate 1, and has an intelligent image recognition function for guiding and determining the transportation path and avoiding obstacles. It also includes a front block component 3, a support plate 5, a side block component 7, a steering component 9, and an active connection component 12. Two support plates 5 are arranged in parallel below the loading plate 1, two driving wheels 4 are rotatably installed at the same end of the two support plates 5, and two steering wheels 8 are rotatably installed at the other ends of the two support plates 5 respectively. The reinforcement strip 11 is fixed between the inner walls of the two support plates 5. The surface of the reinforcement strip 11 is used to place a battery pack to power each electronic component through the battery pack. The active connection component 12 is installed between the support plate 5 and the loading plate 1. The surface of the single support plate 5 Two groups of movable connection components 12 are provided, the front block component 3 and the steering component 9 are both installed between the side walls of the two support plates 5, and the top of the front block component 3 extends into the limiting groove 2. In the normal driving state, the side wall of the front block component 3 is in contact with the front side of the limiting groove 2, and the side block component 7 is installed on the surface of the loading plate 1. The side block component 7 is arranged in two groups, so that when turning in different directions, there is a group of side block components 7 located outside the turning radius. The control host 10 is respectively connected to the intelligent detection sensor 6, the side block component 7 and the steering component 9. When the steering component 9 is working, the control host 10 connects the power of the side block component 7 located outside the turning radius. After the power of the side block component 7 is turned on, the height is increased, thereby providing support and protection for the carton goods from the outside of the turning radius. When the driving wheel 4 brakes suddenly, the loading plate 1 drives the movable connection component 12 to move forward. When the movable connection component 12 moves forward to the set distance, it pushes the front block component 3 to move up, so as to prevent the carton goods from falling from the front end of the loading plate 1 under the action of inertia.

[0023] Reference Figure 3 As an embodiment of the present invention, specifically, the movable connection component 12 includes a slide groove 121, an elastic rod 122, and a mounting block 123. The slide groove 121 is constructed between the surface of the support plate 5 and the side wall. The end cross-section of the slide groove 121 is L-shaped. The mounting block 123 is slidably arranged in the slide groove 121, and the elastic rod 122 is arranged in the slide groove 121, and the end of the elastic rod 122 is connected to the mounting block 123. When the mounting block 123 moves toward the driving wheel 4 side along the slide groove 121, the elastic rod 122 is in a compressed state. When the external force is lost, the elastic rod 122 will drive the mounting block 123 to move to the side away from the driving wheel 4, thereby driving the loading plate 1 to reset. The movable connection component 12 near the driving wheel 4 side also includes a side strip 124 and a second wedge block 125. The side strip 124 is installed on the side wall of the mounting block 123, and the side strip 124 is arranged between the two support plates 5. The second wedge block 125 is installed at the end of the side strip 124 near the driving wheel 4 side.

[0024] Referring to Figure 4 and Figure 5 As an embodiment of the present invention, specifically, the front windshield assembly 3 includes a connection frame 31, a limiting block 32, and a lifting structure 33. The connection frame 31 is installed between two support plates 5, and the connection frame 31 is fixedly connected to the support plates 5, which can not only improve the stability of the support plates 5, but also provide a limiting function for the lifting structure 33. Two limiting blocks 32 are respectively slidably arranged in the limiting through grooves 2. The end cross-section of the limiting through grooves 2 is in a "cross" shape, and the limiting blocks 32 are installed at the ends of the connection frame 31. The limiting blocks 32 are located at the left and right ends of the limiting through grooves 2. The lifting structure 33 is lapped on the connection frame 31, and the lifting structure 33 extends to the bottom of the connection frame 31. The lifting structure 33 includes a top piece 331, a through frame 332, and a first wedge block 333. The top piece 331 is lapped on the surface of the connection frame 31. The through frame 332 is installed at the bottom of the top piece 331. The bottom of the top piece 331 is wider than the top of the through frame 332. Therefore, under normal circumstances, the top piece 331 can be lapped on the surface of the connection frame 31, and the through frame 332 is slidably connected to the connection frame 31. The first wedge block 333 is integrally formed at the bottom of the through frame 332. The inclined surfaces of the first wedge block 333 and the second wedge block 125 are both constructed on the adjacent sides. When the loading plate 1 and the support plate 5 generate relative displacement, causing the first wedge block 333 and the second wedge block 125 to approach each other continuously, when the first wedge block 333 and the second wedge block 125 come into contact, the inclined surfaces contact first. Then, as they continue to approach, the first wedge block 333 will be pushed upward, thereby lifting the through frame 332 by a certain height. Specifically, referring to Figure 6 such that the through frame 332 blocks the carton goods from moving forward due to inertia from the front side of the carton goods.

[0025] Referring to Figure 7 As an embodiment of the present invention, specifically, the steering assembly 9 includes a reinforcement frame 91, a servo motor 92, a connecting rod 93, and a rotating piece 94. The reinforcement frame 91 is installed between the side walls of two support plates 5. The servo motor 92 is installed on the surface of the reinforcement frame 91. The rotating piece 94 is rotatably connected to one end of the support plate 5 away from the driving wheel 4. The connecting rod 93 is rotatably installed between two rotating pieces 94, and the connecting rod 93 is connected to the servo motor 92 through a connecting bar. One end of the connecting bar connected to the servo motor 92 is fixedly connected, and one end of the connecting bar connected to the connecting rod 93 is rotatably connected. When the servo motor 92 rotates by a certain angle, the servo motor 92 will push the connecting rod 93 in the corresponding direction through the connecting bar, thereby changing the angle between the rotating piece 94 and the support plate 5. An arc portion is constructed in the middle of the connecting rod 93, and the servo motor 92 is located at the center of the arc portion.

[0026] Referring to Figure 8As an embodiment of the present invention, specifically, the side stop assembly 7 includes a vertical frame 71, an electric push rod 72, a connecting block 73 and an X-shaped frame 74. The vertical frame 71 is installed and connected to the loading plate 1, and the top of the vertical frame 71 is flush with the top of the loading plate 1. The vertical frame 71 is located on the side away from the two support plates 5. The electric push rod 72 is installed on the inner bottom surface of the vertical frame 71. The connecting blocks 73 are slidably arranged on both sides of the electric push rod 72, and the connecting blocks 73 on one side are connected to the electric push rod 72. The X-shaped frame 74 is rotatably installed between the tops of the connecting blocks 73. When the electric push rod 72 is retracted, the connecting blocks 73 at the bottom of the X-shaped frame 74 are close to each other, and then the X-shaped frame 74 is unfolded and the top is raised, which can provide lateral support protection for carton goods. When the electric push rod 72 is extended, the connecting blocks 73 at the bottom of the X-shaped frame 74 are away from each other, so that the X-shaped frame 74 can be completely retracted into the vertical frame 71.

[0027] Working principle: When paper towels packed in cartons are stored, after the cartons are stacked on the loading plate 1, the intelligent detection sensor 6 monitors the circulation logistics storage environment, and after determining the travel route, the control host 10 turns on the power of the driving wheel 4, and continuously adjusts the steering component 9 to change the angle of the steering wheel 8, thereby performing intelligent transportation operations; When turning, in order to prevent the carton goods that are not wrapped with plastic film from falling off the edge of the loading plate 1 under the action of centrifugal force, the control host 10 turns on the power of the side block assembly 7 located outside the turning radius according to the action direction of the steering assembly 9, thereby raising the top height of the side block assembly 7, providing support for the carton goods from the outside of the turning radius, and preventing the carton goods from falling off the edge of the outside of the turning radius of the loading plate 1. At the same time, when the driving wheel 4 is quickly braked, the loading plate 1 and the carton goods will move forward together under the action of inertia, thereby making the movable connection assembly 12 contact with the front block assembly 3, and making the top of the front block assembly 3 rise to prevent the goods from moving forward and falling from the front end of the loading plate 1; Specifically, when turning, the steering gear 92 moves the connecting rod 93 in the corresponding direction through the connecting bar. At this time, the control host 10 recognizes the action command of the steering gear 92, and immediately turns on the power of the side block assembly 7 located outside the turning radius. When the electric push rod 72 is initially powered on, it performs a contraction action, and the electric push rod 72 pulls the connecting blocks 73 closer to each other, thereby making the X-shaped frame 74 unfold and the top rise, providing lateral support and protection for the carton goods. Then the control host 10 switches the power of the electric push rod 72, so that the electric push rod 72 extends and returns to its original position. At this time, the connecting blocks 73 at the bottom of the X-shaped frame 74 move away from each other until the X-shaped frame 74 is completely retracted into the vertical frame 71; When braking to a stationary state, under the action of inertia, the loading plate 1 together with the mounting block 123 moves along the chute 121 towards the driving wheel 4 side. As a result, a relative displacement occurs between the loading plate 1 and the support plate 5. However, there is no relative displacement between the first wedge block 333 and the support plate 5. Compared with the support plate 5, the second wedge block 125 generates a displacement towards the driving wheel 4 side under the action of the loading plate 1. Therefore, it can be regarded that the second wedge block 125 and the first wedge block 333 approach each other. During the approach and contact process of the first wedge block 333 and the second wedge block 125, under the action of their inclined surfaces, the first wedge block 333 continuously moves upward under the action of the second wedge block 125, thereby driving the through-frame 332 to move upward along the inner wall of the connection frame 31. The top piece 331 moves upward together with the through-frame 332. The upward-moved top piece 331 and through-frame 332 block the carton goods from the forward side of the carton goods, preventing the carton goods from falling from the front end of the loading plate 1 under the action of inertia. When the second wedge block 125 moves towards the driving wheel 4 side, the elastic rod 122 is continuously compressed. When the loading plate 1 is stationary and the carton goods are removed from the surface of the loading plate 1, under the action of the elastic rod 122, the mounting block 123 is restored to its initial position in the chute 121, and the loading plate 1 is reset together with it.
