Description

Technical Field

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

[0002] Logistics warehousing refers to a series of activities such as warehousing, storing, keeping, and out-of-warehouse of goods by using warehouses and related facilities and equipment. It is not only a place for storing goods but also an important node for the flow of goods in the logistics supply chain. Warehousing can be classified into storage-type warehousing and circulation-type warehousing according to functions. Compared with storage-type warehousing, the goods in the circulation-type warehousing used by e-commerce supporting manufacturers have a fast turnover speed, which can support the rapid circulation of goods.

[0003] Considering that a large amount of manpower is required for goods handling and management in logistics warehousing, in order to reduce the dependence on manual labor and thus reduce labor costs. Therefore, most of the circulation-type warehousing used by e-commerce supporting manufacturers choose intelligent transportation equipment for goods handling and management. The intelligent transportation equipment can accurately control the storage and handling of goods, reduce space waste, improve the utilization rate of warehousing facilities, effectively reduce labor costs, and thus improve the economy of logistics warehousing.

[0004] At present, when the intelligent transportation equipment used in circulation-type warehousing transfers paper towels packed in cartons, since several layers of cartons need to be loaded at a time, the center of gravity of the paper towels and the cartons is above the intelligent transportation equipment. When the intelligent transportation equipment moves in the logistics warehousing, it is inevitable to turn. When turning, the carton goods at a certain height are extremely likely to fall from the outer edge of the turning side of the intelligent transportation equipment under the action of centrifugal force. To prevent the carton goods from falling when the intelligent transportation equipment turns, the prior art often uses simple binding by winding plastic film on the outer side of the carton goods, or greatly reducing the turning speed when the intelligent equipment turns. The above operations will cause low efficiency in handling carton goods, resulting in limited economy of logistics warehousing.

[0005] Therefore, an intelligent transportation device for logistics warehousing is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent transportation device for logistics warehousing. By starting the side baffle assembly located outside the turning radius when turning to provide lateral protection for the carton goods, and blocking the forward movement of the goods from the front side of the goods during emergency braking, the problem that the existing intelligent transportation equipment needs to wind plastic film on the carton goods or greatly reduce the turning speed, resulting in low efficiency in transferring carton goods by the intelligent transportation equipment and having an adverse impact on the economy of logistics warehousing is solved. It has the effects of not requiring additional binding of the carton goods, effectively increasing the turning speed of the intelligent transportation equipment, not affecting the later handling of the goods, effectively improving the handling efficiency of the goods, and enhancing the economy of logistics warehousing.

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

[0008] An intelligent transportation device for logistics warehousing comprises a loading plate, a limit slot, a driving wheel, an intelligent detection sensor, a steering wheel, a control host, a reinforcement bar, and also comprises a front block assembly, a support plate, a side block assembly, a steering assembly, and a movable connection assembly. Two support plates are arranged in parallel below the loading plate, and the movable connection assembly is installed between the support plate and the loading plate. The front block assembly and the steering assembly are both installed between the side walls of the two support plates, and the top of the front block assembly extends into the limit slot, and the side block assembly is installed on the surface of the loading plate. The control host is respectively connected to the intelligent detection sensor, the side block assembly and the steering assembly. When the steering assembly is working, the control host connects the power supply of the side block assembly located outside the turning radius. When the driving wheel brakes suddenly, the loading plate drives the movable connection assembly to move forward, and when the movable connection assembly moves forward to a set distance, it pushes the front block assembly to move upward.

[0009] In the above scheme, when storing paper towels packaged in cartons, in order to improve the transfer efficiency, 4-5 layers of cartons will be stacked on the intelligent transportation equipment at a time. The height of a single-layer carton is about 30 cm, so the center of gravity of the stacked paper towel packaged goods is about 60-80 cm. When turning, the turning speed of the intelligent transportation equipment should be controlled within the range of 3.6-5.4 kilometers per hour. Therefore, it can be seen that the turning speed of the intelligent transportation equipment is greatly restricted, resulting in limited transportation efficiency of the intelligent transportation equipment. If this turning speed limit is exceeded, it is necessary to use plastic film to temporarily restrain the carton goods. This will not only increase the cost of intelligent transportation, but also the plastic film needs to be torn off when taking out a single box of paper towels separately. It is particularly inconvenient when shipping by e-commerce, and therefore will lead to reduced economy of logistics warehousing. To this end, the present technical solution uses an X-shaped frame in the side stop assembly located outside the turning radius to expand when the storage and conveying equipment turns, 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 turn. Not only does it not need to use additional plastic film to restrain the carton goods, simplifying the transportation process, but it can also effectively improve the turning speed of the intelligent transportation equipment, and will not interfere with the removal of the carton goods from the intelligent transportation equipment, which greatly improves the transportation efficiency of the intelligent transportation equipment used in circulating logistics warehousing, and will not increase additional costs, which is conducive to greatly improving the economy of logistics warehousing.

[0010] Preferably, the movable connection assembly includes a slide groove, an elastic rod, and a mounting block, the slide groove is constructed between the support plate surface and the side wall, the mounting block is slidably set in the slide groove, the elastic rod is set in the slide groove, and the end of the elastic rod is connected to the mounting block.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 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.

[0019] 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 main body 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, avoiding 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, thus effectively ensuring the transportation efficiency of the intelligent transportation device.

[0020] 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 using 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. Thus, the intelligent transportation device can stop in a shorter time or transport the carton goods at a higher speed, also effectively improving the transportation efficiency of the carton goods.

Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 8 , the present invention provides an intelligent transportation device for logistics warehousing, and the technical solution is as follows:

[0032] Refer to 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.

[0033] 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.

[0034] Referring to Figure 4 and Figure 5 As an embodiment of the present invention, specifically, the front windshield assembly 3 includes a connecting frame 31, a limiting block 32, and a lifting structure 33. The connecting frame 31 is installed between two support plates 5, and the connecting 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 connecting 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 connecting frame 31, and the lifting structure 33 extends to the bottom of the connecting 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 connecting frame 31, and 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 placed on the surface of the connecting frame 31, and the through frame 332 is slidably connected to the connecting 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 so that the through frame 332 blocks the carton goods from moving forward due to inertia from the front side of the carton goods.

[0035] 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 strip. One end of the connecting strip connected to the servo motor 92 is fixedly connected, and one end of the connecting strip 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 strip, thereby changing the angle between the rotating piece 94 and the support plate 5. An arc-shaped portion is constructed in the middle of the connecting rod 93, and the servo motor 92 is located at the center of the arc-shaped portion.

[0036] 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.

[0037] 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;

[0038] 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;

[0039] 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;

[0040] When braking to a stationary state, under the action of inertia, the loading plate 1 together with the mounting block 123 moves along the sliding groove 121 towards the driving wheel 4 side. As a result, a relative displacement occurs between the loading plate 1 and the support plate 5. The first wedge block 333 and the support plate 5 do not have a relative displacement. 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 connecting 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 the initial position in the sliding groove 121, and the loading plate 1 is reset together.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
