Description

Technical Field

[0001] This application relates to the field of material filling equipment, specifically to a lifting receiving and weighing device and filling system with horizontal adjustment function. Background Technology

[0002] In industrial filling production, the stability and adaptability of receiving and weighing equipment directly affect production efficiency and material metering accuracy. Traditional equipment often uses a fixed-height weighing platform, which is difficult to adapt to different sizes of receiving containers, leading to improper distance between the container and the filling port, easily causing problems such as material splashing and air bubbles. In addition, the leveling adjustment of existing equipment relies on manual operation, which has a slow response and low accuracy. Tilting the weighing platform will significantly affect the weighing accuracy. At the same time, the low degree of automation of manual loading and unloading further limits production efficiency. Therefore, how to develop a receiving and weighing equipment and filling system that can automatically adapt to multiple container sizes, level in real time, and integrate automated loading and unloading has become a key focus for industry professionals.

[0024] The embodiments in this application are written in a progressive manner.

The weighing platform is used to support the receiving container 40 and for weighing. A leveling mechanism is installed between the weighing platform and the lifting platform. A level sensor is installed on the weighing platform. The leveling mechanism is used to adjust the position of the weighing platform.

[0026] The material receiving and weighing equipment of this application uses a controller to preset the height of the receiving container and drive the lifting platform to adjust to the target position. Simultaneously, a level sensor monitors the weighing platform's status in real time, and a leveling mechanism dynamically adjusts the platform, thus solving the problems of inaccurate positioning and weighing errors when switching between multiple container sizes. This solution can adapt to various container sizes, achieving high-precision level control and automated material receiving, improving filling efficiency and weighing accuracy.

[0027] Furthermore, the lifting platform 10 includes: Base 11, A scissor fork structure 12 is positioned opposite each other on the base; Top platform 13 is arranged on the scissor fork structure; And a linear module 14, which is arranged on the base and connected to the scissor fork structure to drive the opening, closing and lifting of the scissor fork structure.

[0028] See Figure 3 The scissor fork structure includes: a diagonal support rod 121 and a diagonal brace rod 122 hinged in the middle to form a scissor-like structure; The top platform has slide rails on two opposite sides at its bottom, and a first slider and a second slider are mounted on the slide rails.

One end of the diagonal brace is connected to the slide block 141 of the linear module on the base, and the other end of the diagonal brace is connected to the second slider.

[0029] The linear module's slide drive brace moves horizontally to control the opening and closing of the scissor fork structure; the linear module is a conventional ball screw type linear module, and in this application, the motor of the linear module is preferably a servo stepper motor. The motor of the linear module is electrically connected to the controller, and its operation is controlled by the controller.

[0030] Furthermore, the weighing platform includes: a weighing frame, a weighing platform, and a weighing sensor installed between the weighing frame and the weighing platform to weigh and detect the weight of the container and material received on the weighing platform.

[0032] Furthermore, the leveling mechanism includes multiple electric push rods 20 distributed around the bottom periphery of the weighing platform, evenly supporting the platform. One end of each electric push rod is mounted on a lifting platform, and the other end is connected to the bottom of the weighing platform. The electric push rods are connected to a controller, which controls their operation. Specifically, the controller controls the extension and retraction of each electric push rod based on the horizontal tilt angle information detected by the level sensor, thereby ensuring the leveling of the weighing platform. The level sensor detects the tilt angle signal, and the controller analyzes and calculates the compensation amount of the electric push rods to achieve the leveling of the weighing platform.

[0033] Furthermore, the weighing platform has a square or circular structure; the square structure has an electric push rod at the center of each of the four sides at the bottom; the circular structure has four electric push rods at the bottom that divide the circumference equally, with the central angle between adjacent push rods being 90 degrees.

[0034] Furthermore, the material receiving and weighing equipment of this application also includes: a loading and unloading robot installed next to the lifting platform.

[0037] It is understandable that the height of receiving containers of different specifications is known information, the height of the discharge port in the filling barrel is known information, and the lifting height information of the lifting platform can be obtained by the encoder configured in the servo stepper motor in the linear module. That is, the controller controls the lifting height of the lifting platform by controlling the operation of the servo stepper motor.

[0038] The controller pre-stores the height parameters of receiving containers of different specifications and instructs the servo stepper motor to adjust the height of the weighing platform so that the distance between the discharge port (filling gun nozzle) and the material liquid surface remains at a preset value. When the lifting stops, the controller uses electric push rods to finely adjust and level the weighing platform based on the tilt signal of the level sensor, and controls the extension and retraction of each electric push rod to keep the weighing platform horizontal so that the receiving container can receive the material. According to the weight of the receiving container after receiving the material, fed back by the weighing sensor, the controller instructs the servo stepper motor of the lifting platform to adjust the height of the weighing platform to lower so that the loading and unloading robot can perform the material picking up of the receiving container.

Alternatively, the filling gun nozzle is equipped with a barrier filter, and a vibrator is also installed on the outer wall of the filling gun nozzle. The vibrator vibrates to force the material through the barrier filter for filling. It is understood that the vibrator is connected to a controller, and the controller controls the vibration.
