Description

Technical Field

[0001] This application belongs to the technical field of automatic loading equipment, and more specifically, relates to an automatic detection device for the position of a freight car compartment and an automatic loading equipment. Background Technology

[0002] In logistics and industrial production, automated loading equipment is increasingly widely used, improving loading efficiency and reducing labor costs. As a common cargo-carrying structure, the height of the cargo compartment and the distance between pallets in low-bed trailers directly affect the operational accuracy of automated loading equipment. Inaccurate detection can easily lead to problems such as cargo misalignment and collisions. Existing automated loading equipment generally uses vision inspection systems for position determination. However, when determining the length and position of low-bed trailers or the distance between pallets, vision inspection systems are affected by lighting conditions, resulting in insufficient accuracy and potential control errors. Utility Model Content

[0003] To address the shortcomings of the prior art, the purpose of this application is to provide an automatic truck bed position detection device that uses two laser sensors to locate the position of the truck bed on different levels. This device has the advantages of simple detection method and accurate positioning. At the same time, it uses a drive rotation component to extend and retract the position detection sensors, avoiding damage to the position detection sensors during movement.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an automatic detection device for the position of a freight car body, which is installed on the lifting bracket of an automatic loading equipment, including: a first mounting bracket, a first position detection sensor, a drive rotation assembly, a second mounting bracket, and a second position detection sensor;

[0005] Two first mounting brackets are provided and fixed on both sides of the lifting bracket respectively. The first position detection sensor is fixed on the first mounting bracket. The first position detection sensor is used to detect the height of the carriage and the distance from the carriage.

[0006] Two drive rotation assemblies are provided and fixed on both sides of the lifting bracket respectively. Each drive rotation assembly is fixed with a second mounting bracket and a second position detection sensor is installed on each second mounting bracket. The drive rotation assembly drives the second mounting bracket to rotate so that the second position detection sensor extends or retracts. The second position detection sensor is used to detect the distance from the front of the vehicle and the spacing between the pallets.

[0007] In one embodiment, the drive rotation assembly includes: a fixed plate, a mounting base, a first synchronous pulley, a synchronous belt, a second synchronous pulley, a connecting shaft, and a drive motor;

[0008] The fixing plate is fixed on the lifting bracket, the mounting base is fixed on the fixing plate, the drive motor is mounted on the mounting base and is connected to the first synchronous pulley for transmission, the connecting shaft is rotatably mounted on the mounting base, one end of the connecting shaft is fixedly connected to the second synchronous pulley, and the other end is fixedly connected to the second mounting bracket. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt for transmission.

[0009] In one embodiment, the drive motor is connected to the first synchronous pulley via a speed reducer; the connecting shaft is rotatably connected to the mounting base via a bearing.

[0010] In one embodiment, a limiting block is fixed on the mounting base to restrict the rotation angle of the second mounting bracket from the initial position to the final position.

[0011] In one embodiment, the mounting base is provided with a protective cover that covers the first synchronous pulley, the synchronous belt, and the second synchronous pulley.

[0012] In one embodiment, both the first mounting bracket and the second mounting bracket are made of aluminum profiles; the first mounting bracket includes three aluminum profiles, and the second mounting bracket includes two aluminum profiles; the two aluminum profiles are connected by a triangular bracket assembly.

[0013] In one embodiment, the other end of the connecting shaft is fixed to a connecting plate by a first fastener, and the connecting plate is fixedly connected to a connecting block installed in the aluminum profile by a second fastener.

[0014] In one embodiment, the second mounting bracket is provided with a photoelectric bracket, and the second position detection sensor is fixed on the photoelectric bracket and located inside the edge of the photoelectric bracket; the drive motor is a servo motor with a torque anti-collision mode.

[0015] In one embodiment, both the first position detection sensor and the second position detection sensor are laser sensors.

[0016] Another object of this application is to provide an automatic loading device, including the automatic vehicle loading device for detecting the position of the freight car body as described above.

[0017] The advantages of the automatic truck cargo compartment position detection device provided in this application are as follows:

[0018] 1. The position of the carriage is detected by a first position detection sensor and a second position detection sensor. The position is not affected by light during the measurement and positioning. It has the advantages of simple detection method, accurate positioning and low cost.

[0019] 2. During the loading process, the second mounting bracket and the second position detection sensor can be extended and rotated under the action of the drive rotation component. After use, they can be retracted. The structure is compact, easy to use, and does not affect the use of the automatic loading equipment. At the same time, the extension and retraction of the second mounting bracket and the second position detection sensor are carried out by the drive rotation component, avoiding damage to the second position detection sensor during the movement.

[0020] 3. Use a limiting block to limit the angle of the second mounting bracket in the extended state to ensure that it is in a horizontal state, thereby ensuring the accuracy of the second position detection sensor.

[0021] 4. Install the second position detection sensor inside the edge of the photoelectric bracket. The drive motor is a servo motor with torque anti-collision mode. When the drive motor drives the second mounting bracket to rotate, if the second mounting bracket or the photoelectric bracket first hits another object, and the torque generated by the other object blocking the rotation of the second mounting bracket is greater than the torque set by the torque anti-collision mode, the drive motor stops working and reverses to reset. The staff then conducts an inspection. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] like Figures 1-7 As shown, an automated loading device provided in this application embodiment will now be described. This automated loading device loads goods onto the side of a truck. A track 10 is provided on the ground, and the automated loading device is installed on the track 10 and can move along it. This automated loading device is existing equipment, and its specific structure will not be described in detail. Generally, it includes an equipment assembly 20 and a lifting bracket 30. The equipment assembly 20 is used to realize the multi-directional movement of the lifting bracket 30 in front-back, up-down, and left-right directions. The lifting bracket 30 is used to transport goods, which are placed on a pallet. The lifting bracket 30 is equipped with forks. The equipment assembly 20 has a control system. In this embodiment, the truck is a low-bed truck.

[0037] The improvement of this embodiment is that an automatic truck bed position detection device is provided on the lifting bracket 30, which is used to detect the relative position of the truck bed, the height position of the truck bed, the length position of the truck bed and the spacing between the pallets during the loading process, so as to ensure the accurate placement of goods.

[0038] Specifically, the automatic truck body position detection device includes a first mounting bracket 1, a first position detection sensor 2, a drive rotation assembly 3, a second mounting bracket 4, and a second position detection sensor 5. Two first mounting brackets 1 are provided and fixed to both sides of the lifting bracket 30. Two corresponding first position detection sensors 2 are provided and fixed to their respective first mounting brackets 1. The first position detection sensors 2 are used to detect the height of the truck body and the distance from the truck body; here, the distance from the truck body refers to the distance between the first position detection sensor 2 and the side of the truck body. Based on this distance, the distance between the lifting bracket 30 and the truck body can be determined.

[0039] Two drive rotation components 3 are provided and fixed on both sides of the lifting bracket 30 respectively. Each drive rotation component 3 has a second mounting bracket 4 fixed on it, and each second mounting bracket 4 has a second position detection sensor 5 installed on it. The drive rotation component 3 drives the second mounting bracket 4 to rotate so that the second position detection sensor 5 can extend or retract. In this embodiment, the drive rotation component 3 drives the second mounting bracket 4 to rotate by 90° to realize the retraction and extension of the second position detection sensor 5. The second position detection sensor 5 is used to detect the position of the truck bed in the length direction, such as the distance from the front of the truck and the spacing between the pallets. In this embodiment, the first mounting bracket 1 and the first position detection sensor 2 are far away from the truck and will not collide with it; the second mounting bracket 4 and the second position detection sensor 5 are close to the truck and can extend into the truck during the rotation and extension process. The purpose of this arrangement is to ensure that the goods can be detected by the second position sensor 5 even when they are placed in the center on the truck.

[0040] Goods are placed one by one from the front to the rear of the vehicle. When detecting the position of the cargo compartment, the lifting bracket 30 is raised to its highest position, the second position detection sensor 5 is in the retracted state, and then the lifting bracket 30 slowly descends. The first position detection sensor 2 detects in real time. Since the detection data will be large at the beginning when there is no cargo on the cargo compartment, the data will decrease after the cargo compartment is detected. Therefore, the change in detection data is used to determine whether the cargo compartment has been detected. For example, if the detected data decreases from large to small and then remains stable for a period of time (the height of the side of the cargo compartment) before descending, it means that the side of the cargo compartment has been detected. At this time, the height of the cargo compartment can be determined based on the descent height. And the distance from the cargo compartment; then the lifting bracket 30 rises to its highest point again, and the second position detection sensor 5 rotates 90° under the drive of the drive rotation component 3, extending into the cargo compartment. The second position detection sensor 5 detects in real time. When the descent height is lower than the height of the truck head, initially when there is no cargo on the cargo compartment, the distance from the truck head can be detected; when there is cargo on the cargo compartment (the height of the cargo is generally lower than the height of the truck head), from top to bottom, the second position detection sensor 5 first detects the distance from the truck head, then the distance from the cargo, and then the distance from the pallet. After the detection is completed, the second position detection sensor 5 retracts. The control system of the equipment assembly 20 controls the lifting bracket 30 to move back and forth, up and down, and left and right according to the data detected by the first position detection sensor 2 and the second position detection sensor 5, so as to accurately place the cargo in the corresponding position of the truck.

[0041] Specifically, such as Figure 5-7 As shown, the drive rotation assembly 3 includes: a fixed plate 31, a mounting base 32, a first synchronous pulley 33, a synchronous belt 34, a second synchronous pulley 35, a connecting shaft 36, a drive motor 37, and a reducer 38. The fixed plate 31 is fixed to the lifting bracket 30 with fastening screws, and the mounting base 32 is fixed to the fixed plate 31 with fastening screws. The drive motor 37 is connected to the reducer 38, and the reducer 38 is fixed to the mounting base 32 with fastening screws. The first synchronous pulley 33 is fixed to the output shaft of the reducer 38. The connecting shaft 36 is rotatably mounted on the mounting base 32 via a bearing 39. The second synchronous pulley 35 is fixed to one end of the connecting shaft 36. The first synchronous pulley 33 and the second synchronous pulley 35 are located on the same side of the mounting base 32 and are connected by the synchronous belt 34. The other end of the connecting shaft 36 is connected to the second mounting bracket 4. The drive motor 37 operates, which in turn drives the reducer 38 to rotate, thereby driving the first synchronous pulley 33 to rotate. Through the synchronous belt 34, the second synchronous pulley 35 rotates, thereby driving the connecting shaft 36 to rotate. When the connecting shaft 36 rotates, it drives the second mounting bracket 4 to rotate, thereby realizing the retraction and extension of the second position detection sensor 5.

[0042] In this embodiment, a limit block 310 is fixed to the mounting base 32 by fastening screws. In this embodiment, the second mounting bracket 4 is in the initial position (i.e., as shown in the image). Figure 4 (as shown in the retracted state), in a vertical state, when the second mounting bracket 4 is at the end position (i.e., as shown in the retracted state). Figure 3 As shown in the extended state), it is in a horizontal state, and in this horizontal state, the second mounting bracket 4 is placed on the limiting block 310. Therefore, the limiting block 310 is used to limit the rotation angle of the second mounting bracket 4 from the initial position to the end position. In this embodiment, the rotation angle from the initial position to the end position is 90°.

[0043] Specifically, a protective cover 311 covering the first synchronous pulley 33, the synchronous belt 34, and the second synchronous pulley 35 is fixed on the mounting base 32 by fastening screws.

[0044] In this embodiment, both the first mounting bracket 1 and the second mounting bracket 4 are made of aluminum profiles. The first mounting bracket 1 includes three aluminum profiles: two vertically arranged and one horizontally arranged. The two ends of the horizontally arranged aluminum profile are connected to the two vertically arranged aluminum profiles via triangular bracket assemblies 42, which are conventional structures. The second mounting bracket 4 includes two aluminum profiles arranged in an L-shape; the two aluminum profiles are connected by the triangular bracket assemblies 42.

[0045] Specifically, one end of the connecting shaft 36 is fixedly connected to the second synchronous pulley 35, and the other end face of the connecting shaft 36 is fixed to the connecting plate 312 by a first fastener such as a screw. The connecting plate 312 is fixedly connected to the connecting block installed in the aluminum profile by a second fastener such as a screw. The connecting block is provided in the groove of the aluminum profile, and the connecting block is provided with a threaded hole. The second fastener passes through the hole on the connecting plate 312 and is threadedly connected to the threaded hole, thereby realizing the fixed connection between the connecting shaft 36 and the second mounting bracket 4. The first mounting bracket 1 is connected to the lifting bracket 30 by multiple L-shaped brackets and fastening screws.

[0046] In this embodiment, both the first mounting bracket 1 and the second mounting bracket 4 are equipped with photoelectric brackets 41, and the first position detection sensor 2 and the second position detection sensor 5 are respectively fixed on the photoelectric brackets 41. Preferably, the first position detection sensor 2 and the second position detection sensor 5 are both laser sensors, utilizing the advantages of laser sensors such as accurate measurement, high speed, large range, and anti-light properties to ensure measurement accuracy. The edge of the photoelectric bracket 41 is flush with the end face of the second mounting bracket 4, or the edge of the photoelectric bracket 41 is located within the end face of the second mounting bracket 4. In this embodiment, the second position detection sensor 5 is installed inside the edge of the photoelectric bracket 41, that is, the second position detection sensor 5 does not protrude from the edge of the photoelectric bracket 41. The drive motor 37 adopts a servo motor with torque anti-collision mode in the prior art. When the drive motor 37 drives the second mounting bracket 4 to rotate and extend, the second mounting bracket 4 or the photoelectric bracket 41 will first hit other objects (such as goods on the carriage), thus preventing the second position detection sensor 5 from being damaged. When the torque generated by the other object blocking the rotation of the second mounting bracket 4 or the photoelectric bracket 41 is greater than the torque set by the torque anti-collision mode, the drive motor 37 stops working and reverses to reset, preventing the drive motor 37 from being damaged. The staff will then check and readjust the position through the equipment assembly 20.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
