Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vertical lifting cabinets, and particularly relates to an automatic height measuring and weighing integrated structure of an intelligent vertical lifting cabinet. BACKGROUND

[0002] With the rapid development of automatic storage, intelligent manufacturing and logistics industry, the demand for vertical lifting cabinets with high space utilization rate and fast access efficiency is increasing. In order to realize fine management of goods, modern intelligent cabinets usually need to integrate automatic height measuring and weighing functions to obtain three-dimensional size and weight information of goods, which are used for core links such as inventory management, space planning and load warning.

[0003] However, the existing device measures height and weighs in steps and independently, which leads to low efficiency. The traditional structure needs to be positioned and measured in height first, and then moved to the weighing area for weighing. Single goods processing needs two mechanical movements, which takes a long time. In high-concurrency storage scenarios, the access efficiency bottleneck is obvious.

[0004] Therefore, the present application provides an automatic height measuring and weighing integrated structure of an intelligent vertical lifting cabinet to solve the above problems. SUMMARY

[0005] Technical problems to be solved

[0006] In view of the above shortcomings of the prior art, the present application provides an automatic height measuring and weighing integrated structure of an intelligent vertical lifting cabinet, which can solve the problem of low efficiency caused by the step-by-step height measuring and weighing of the traditional cabinet. The simultaneous completion of goods height measurement and weight detection is realized, which significantly improves the purpose of warehouse operation efficiency.

[0007] Technical scheme

[0008] To achieve the above purpose, the present application realizes the following technical scheme:

[0009] The present application provides an automatic height measuring and weighing integrated structure of an intelligent vertical lifting cabinet, which comprises a cabinet body, an internal vertical distribution of shelves, a lifting device for controlling the up and down movement of the height measuring and weighing mechanism in the cabinet body, the height measuring and weighing mechanism further comprising a lifting platform connected to the lifting device and used for carrying goods, a rotatable weighing platform on the lifting platform, a cross steel beam and a weighing sensor at the bottom of the lifting platform; wherein the lifting platform further comprises a height measuring sensor and a balancing mechanism for measuring the height of the goods, and the balancing mechanism is used to compensate for the centrifugal force error generated when the weighing platform rotates.

[0010] Furthermore, the balancing mechanism includes a rotatable ring and a crossbar, the crossbar being fixed to the ring and having a lead screw mounted on it; wherein the lead screw is elastically connected to a tension slider via a second spring.

[0011] Furthermore, the balancing mechanism also includes a limiting block, which is mounted on the lead screw and used to limit the sliding range of the tension slider. The limiting block is also equipped with a baffle for buffering via a first spring.

[0012] Furthermore, the surface of the weighing platform is provided with a V-shaped groove for positioning and stabilizing the goods.

[0013] Furthermore, an elastic base plate for measuring the amount of cargo sinking is provided at the center of the V-shaped groove.

[0014] Furthermore, the surface of the weighing platform is also equipped with an anti-tipping device, which consists of an adjustable sleeve, a sliding rod, and an arc-shaped anti-tipping plate. The arc-shaped anti-tipping plate is rotatably connected to the upper end of the adjustable-length sleeve and the sliding rod, and is positioned on the surface of the goods by changing the angle and position to prevent tipping.

[0015] Furthermore, a lower base is connected below the lifting platform, and a rotating shaft is rotatably connected to the lower base. The cross steel beam is mounted on the rotating shaft, and a drive device for driving the weighing platform to rotate is provided on the lifting platform. The drive device is connected to a fixed shaft through a transmission component.

[0016] Furthermore, the transmission component includes a driving wheel connected to a rotating shaft and a driven wheel connected to a fixed shaft, and the driving wheel and the driven wheel are connected by a connecting member.

[0017] Furthermore, a drive gear is also connected to the fixed shaft, and an annular frame is located on the lower surface of the weighing platform, with the rotating ring rotatably connected to the annular frame.

[0018] Furthermore, there are four height sensors, which are respectively installed at the four corners of the lifting platform.

[0019] Beneficial effects

[0020] The technical solution provided by this invention has the following advantages compared with the prior art:

[0021] This invention integrates the traditional step-by-step height measurement and weighing process into a single action through the linkage design of a rotating weighing platform and height sensors. As the weighing platform rotates, the four corner height sensors scan synchronously, achieving 360° height measurement without blind spots. Simultaneously, the weighing sensor at the bottom of the crossbeam collects weight data in real time, shortening the time required for each operation.

[0022] By coordinating the rotating ring and the crossbeam, the position of the tension slider is precisely adjusted by the motor, thus counteracting the influence of the rotational centrifugal force on the weighing accuracy in real time.

[0023] The V-groove, combined with the elastic base plate, enables both self-centering and sinking detection. When a conical cargo is placed, the elastic deformation can automatically compensate for the height measurement value.

[0024] The adjustable anti-tilt device, through the combination of a sleeve and an arc-shaped anti-tilt plate, effectively suppresses the risk of tipping over when the center of gravity of the goods is shifted during rotation, ensuring the stability of the measurement process.

[0039] The present invention will be further described below with reference to embodiments.

[0040] Example:

[0041] Please refer to the appendix. Figures 1-8 This solution proposes an integrated structure for automatic height measurement and weighing of intelligent vertical lifting containers, solving the inefficiency problem caused by the need for step-by-step height and weight measurement in traditional containers. It achieves simultaneous height measurement and weight detection, significantly improving warehousing efficiency. Its innovative use of a rotating weighing platform combined with a centrifugal force compensation mechanism ensures measurement accuracy while enabling the acquisition of three-dimensional dimensions and weight data of the goods in a single mechanical action, achieving the technical objectives of optimizing space utilization and enhancing the adaptability of irregularly shaped goods.

[0042] The cabinet 1 has two vertically arranged shelves 2 inside for storing pallets. The cabinet 1 is made of tubular frame structure and sheet metal, which keeps the shelves 2 in a sealed environment inside the cabinet 1. This effectively prevents dust, dirt and other external pollutants from entering, thus protecting the cleanliness and integrity of the goods. This is especially important in industries with high environmental requirements, such as food, pharmaceuticals and electronic components.

[0043] Meanwhile, the sealed space can work more effectively with the temperature control and dehumidification systems to provide a constant storage environment, ensuring that sensitive goods remain in optimal condition. The surface of cabinet 1 is equipped with access ports 4 for storing and retrieving goods into and from cabinet 1.

[0044] Meanwhile, a lifting device is installed inside the cabinet 1 between the two sets of shelves 2 to control the vertical lifting and lowering of the height measuring and weighing mechanism 3 between the two rows of shelves 2. When the height measuring and weighing mechanism 3 moves to the storage port 4, it can transfer the goods pallet placed at the storage port 4 to its upper part, and then move the goods pallet to different heights on the shelves 2 on both sides, and then transfer the goods pallet back to the shelves 2, thus realizing the storage of goods in the cabinet 1.

[0045] Meanwhile, during the mechanical transfer of goods by the height measuring and weighing mechanism 3, the height and weight of the goods can be measured simultaneously, and the goods of corresponding height and weight can be moved to the shelf 2 with corresponding spacing and load-bearing capacity to achieve safe storage of the goods.

[0046] The difference is that the height measuring and weighing mechanism 3 includes a lifting platform 301 installed on the lifting device, which is used to support the goods and control the lifting and lowering movement of the goods in the cabinet 1 so as to place the goods on the shelves 2 at different heights for storage.

[0047] A weighing platform 302 is rotatably connected to the surface of the lifting platform 301. A cross steel beam 303 is connected to the lower surface of the weighing platform 302, and a weighing sensor 304 is installed at each of the four ends of the cross steel beam 303. When goods are placed on the weighing platform 302, the weighing sensor 304 can weigh the goods, thereby realizing the weight measurement of the goods during the movement process.

[0048] Height sensors 305 are installed at the four corners of the upper surface of the lifting platform 301. When the goods are placed on the weighing platform 302, the height of the goods can be measured by the height sensors 305, so as to facilitate the automatic adjustment of the layer spacing of the shelf 2 according to the height of the goods, avoiding space waste caused by fixed layer height, such as flexible adaptation of irregularly shaped goods or goods of different sizes.

[0049] The lower base 306 is connected to the lower part of the lifting platform 301. A rotating shaft 308 is rotatably connected to the lower base 306. The upper end of the rotating shaft 308 is fixedly connected to the weighing sensor 304, thereby supporting the weighing platform 302 and ensuring the stability of the goods when they move.

[0050] A drive unit 307 is also installed on the lower base 306. The drive unit 307 drives the rotating shaft 308 to rotate, thereby enabling the weighing platform 302 to rotate on the lifting platform 301. When the goods are irregularly shaped, such as L-shaped or conical, or when the center of gravity is offset, such as when one side of the stacked goods protrudes, the height sensor 305 can only measure the height of the edge of the goods and cannot obtain the highest point of the central area, resulting in insufficient shelf height setting of the container and subsequent collisions during storage and retrieval. By rotating the goods through the weighing platform 302, the four sets of height sensors 305 continuously monitor the height during the rotation of the goods. For example, after rotating a fixed angle, the height is monitored once. After the goods complete one full rotation, multiple height marks are formed on the scale, which makes it easy to read the maximum height of the goods and facilitates the safe storage of the goods.

[0051] It should be noted that during the rotation of the goods by the weighing platform 302, the goods are affected by centrifugal force, causing the total weight measured by the weighing sensor to include a centrifugal force component, resulting in a deviation in the weighing value as the rotation speed fluctuates. By installing a balancing mechanism below the weighing platform 302, the centrifugal force generated during the movement of the goods is counteracted, thereby ensuring the accuracy of the weighing measurement.

[0052] Specifically, a fixed shaft 311 is rotatably connected to the surface of the lower base 306. The balancing mechanism includes a drive gear 312 mounted on the fixed shaft 311. The rotating shaft 308 and the fixed shaft 311 are rotatably connected via a transmission component. Thus, when the drive device 307 drives the weighing platform 302 to rotate, the transmission component synchronously controls the operation of the balancing mechanism, thereby achieving synchronous drive of the balancing mechanism and the weighing platform 302. The transmission component includes a driving wheel 310 connected to the rotating shaft 308 and a driven wheel 313 connected to the fixed shaft 311. The driving wheel 310 and the driven wheel 313 are connected via a connecting member 314. The transmission component can be a chain and sprocket or a pulley and belt.

[0053] The balancing mechanism also includes an annular frame 315 connected to the lower surface of the weighing platform 302. A rotating ring 316 is rotatably connected to the surface of the annular frame 315. The inner surface of the rotating ring 316 is provided with internal teeth 317, which mesh with the drive gear 312. When the drive device 307 drives the weighing platform 302 to rotate, it synchronously controls the drive gear 312 to mesh with the internal teeth 317 to drive the rotating ring 316 to rotate. The rotating ring 316 and the weighing platform 302 rotate in the same direction.

[0054] A crossbar 318 is fixedly connected to the surface of the rotating ring 316. A lead screw 319 is rotatably connected to the crossbar 318. A tension slider 321 is slidably mounted on the surface of the lead screw 319. The tension slider 321 is mounted on the crossbar 318 via a second spring 330. When the tension slider 321 is subjected to centrifugal force, it generates a tension force on the second spring 330, thereby enabling the measurement of the centrifugal force of the second spring 330.

[0055] When the weighing platform 302 rotates, the goods on it undergo circular motion, requiring a centripetal force always pointing towards the center of the circle to maintain this motion. This force is provided by the static friction between the weighing platform 302 and the goods. According to Newton's third law, the goods exert an equal and opposite force on the turntable; this force is the centrifugal force, directed outwards along the radius. This outward centrifugal force generates a component force on the load cell. Assuming the load cell is directly below the turntable, this component force reduces the positive pressure on the sensor, causing the weighing reading to be less than the actual weight of the goods. The faster the rotation speed and the farther the goods are from the center, the more severe this deviation becomes.

[0056] A crossbeam 318, coaxial and rotating in the same direction as the weighing platform 302, is installed below the weighing platform 302. A tension slider 321 is mounted on the crossbeam 318. When the crossbeam 318 rotates, the tension slider 321 also generates a centrifugal force. The centrifugal force of the goods is horizontal and outward, transmitted through the turntable structure, and ultimately acts on the load cell, producing a negative weighing deviation. The centrifugal force of the slider is used to compensate for the positive weighing reading generated by the load cell, and to compensate for the weighing loss caused by the centrifugal force.

[0057] To ensure accurate compensation, the additional centrifugal force generated by the tension slider 321 is made equal to the reading loss on the load cell caused by this deviation.

[0058] By precisely adjusting the position of the tension slider 321, the weight loss caused by the centrifugal force of the goods can be exactly equal at any rotational speed. Specifically, a motor 320 is mounted on the surface of the crossbar 318, and the output shaft of the motor 320 is connected to a lead screw 319. A limit block 327 is also fitted onto the surface of the lead screw 319.

[0059] When the tension slider 321 slides outward under the action of centrifugal force, the motor 320 drives the limiting block 327 to slide, which can limit the sliding range of the tension slider 321, thereby limiting the sliding radius of the tension slider 321 and generating different magnitudes of compensation force.

[0060] The side surface of the limiting block 327 facing the pull slider 321 is connected to a baffle 329 via a first spring 328. When the pull slider 321 slides outward under the action of centrifugal force and pulls the second spring 330, the elastic force of the first spring 328 can buffer the direct sliding of the pull slider 321, converting the impact kinetic energy of the pull slider 321 into elastic potential energy and releasing it slowly, thereby playing a buffering role.

[0061] More specifically, when the weighing platform 302 rotates the goods, if the center of gravity of the goods does not coincide with the center of rotation, the centrifugal force will generate an overturning moment. If the friction or contact constraint between the goods and the weighing platform 302 is insufficient, the goods will tilt outward or overturn.

[0062] The surface of the weighing platform 302 is provided with a V-shaped groove 309. Regular goods, such as cylinders, placed in the V-shaped groove 309 will automatically stabilize along the center line of the groove due to the self-centering effect. Rectangular goods can be embedded in the V-shaped groove 309, which restricts their degrees of freedom during rotation. This prevents the goods from tipping over during rotation.

[0063] It is worth noting that the V-groove 309 has an arc-shaped, upward-convex elastic base plate 326 at its center. When goods are placed in the V-groove 309 on the surface of the weighing platform 302, they will abut against the surface of the V-groove 309 and exert pressure on it, causing the V-groove 309 to deform. The deformation of the V-groove 309 can be used to calculate the amount of sinking of the goods, thereby compensating for the height measurement of the height sensor 305 and improving the accuracy of the goods height measurement.

[0064] The surface of the weighing platform 302 is also equipped with an anti-tilting device, including a protrusion 322 connected to the surface of the weighing platform 302. A sleeve 323 is rotatably connected to the surface of the protrusion 322 via a pin. A sliding rod 324 that can be limited and fixed is slidably installed inside the sleeve 323. An arc-shaped anti-tilting plate 325 is connected to the upper end of the sliding rod 324. When the goods are placed on the surface of the weighing platform 302, the position of the anti-tilting plate 325 can be changed by adjusting the length and angle between the sleeve 323 and the sliding rod 324, so that the anti-tilting plate 325 abuts against the outer surface of the goods, thereby supporting the goods.

[0065] When the cargo generates a tipping moment due to centrifugal force, the anti-tipping plate 325 can prevent the cargo from tipping outward. At the same time, the arc-shaped structure of the anti-tipping plate 325 allows the cargo to make slight adjustments in its posture, such as rolling like a cylinder, without tipping over completely.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
