Description

Technical Field

[0001] This application belongs to the field of glass plate production, and specifically relates to a glass plate on-line weighing system. Background Technology

[0002] In the glass sheet production process, measuring the weight after cutting is a crucial step in ensuring product quality. Currently, the mainstream on-line weighing solution involves setting up a dedicated "weighing section" on the conveyor rollers. A pressure sensor is installed below this weighing section, and as the glass sheet passes through it, the sensor detects the overall weight change within the weighing section to determine the weight.

[0003] However, this traditional method suffers from significant accuracy issues. The primary source of interference is mechanical vibration: the continuous rotation of the roller conveyor in the weighing section generates vibration, causing continuous fluctuations in sensor readings and making it difficult to consistently obtain accurate weight values. Secondly, environmental factors severely impact long-term reliability: dust, glass shards, and other impurities generated during production easily accumulate in the weighing section structure (especially near the sensors). This accumulation of non-glass materials leads to a gradual increase in the "tare weight" (unloaded weight) of the weighing section, resulting in a systematically higher measurement. This not only directly impairs weighing accuracy but also forces frequent production line interruptions for manual cleaning and system recalibration, increasing maintenance burdens and impacting efficiency.

[0004] Therefore, there is an urgent need for a new type of glass plate in-line weighing system that can solve the above problems. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a glass plate in-line weighing system that uses a lifting weighing method to weigh the glass plate, which is not affected by dust or other factors, and the weighing accuracy is not affected by the vibration of the roller conveyor.

[0006] The technical effect to be achieved in this application is accomplished through the following solution: According to a first aspect of this application, a glass plate in-line weighing system is provided, comprising a conveyor roller conveyor, a weighing mechanism disposed above the conveyor roller conveyor, the weighing mechanism including a vertical displacement mechanism, a suction cup connected to the bottom of the vertical displacement mechanism, and a pressure sensor disposed between the suction cup and the vertical displacement mechanism. The vertical displacement mechanism includes a vertical displacement winch and a pull rope, a pull frame fixed to the bottom of the pull rope, the pressure sensor disposed on the pull frame, a horizontal plate at the top of the suction cup placed on the pressure sensor, and a driving mechanism connected to the suction cup for extracting or injecting air into the suction cup.

[0007] Preferably, it further includes a traversing mechanism that moves along a track arranged above the conveyor roller conveyor, the track being aligned with the arrangement direction of the conveyor roller conveyor.

[0008] Preferably, the conveyor roller conveyor includes an incoming material area and a feeding area, and a stop is provided at the end of the incoming material area.

[0009] Preferably, the traversing mechanism includes support wheels and a drive motor, the drive motor being drivenly connected to at least one of the support wheels; the track has an I-shaped structure, and the support wheels are supported on both sides of the track.

[0010] Preferably, the weighing mechanism is provided with baffles on the front and rear sides, and the bottom opening of the baffles is not less than the length of the glass plate.

[0011] Preferably, the baffle is a downward-facing funnel shape, and the suction cup is located at the center of the baffle.

[0012] Preferably, the driving mechanism includes an air cylinder and a cylinder, the piston rod of the cylinder is connected to the air cylinder, and the inner cavity of the air cylinder is connected to the suction cup through a hose.

[0013] According to one embodiment of this application, the beneficial effect of using the glass plate in-line weighing system of this application is that the glass plate is lifted up and weighed, which ensures the efficiency of weight detection and does not affect the measurement accuracy due to dust, debris, etc., nor is it affected by the vibration of the roller conveyor.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figures 1 to 5 As shown, the glass plate weighing system in this embodiment includes a conveyor roller conveyor, a weighing mechanism 200 is provided above the conveyor roller conveyor, the weighing mechanism 200 includes a vertical shifting mechanism, a suction cup 220 is connected to the bottom of the vertical shifting mechanism, and a pressure sensor 230 is provided between the suction cup 220 and the vertical shifting mechanism.

[0018] In this embodiment, when the glass plate reaches the designated area, the vertical movement mechanism controls the suction cup 220 to descend onto the glass plate. After the suction cup 220 starts to fix the glass plate, the vertical movement mechanism rises to lift it and suspend it. The pressure sensor 230 detects the weight change to complete the weighing operation.

[0019] A driving mechanism is connected to the suction cup 220, which is used to extract or inject air into the suction cup 220. The driving mechanism includes an air cylinder 410 and a cylinder 420. The piston rod 421 of the cylinder 420 is connected to the air cylinder 410, and the inner cavity of the air cylinder 410 is connected to the suction cup 220 through a flexible hose 411. By pushing and pulling the piston rod 421 of the cylinder, air can be extracted or injected into the suction cup 220, thereby achieving the adsorption or release of the glass plate.

[0020] Several suction cups 220 can be provided. To improve the adsorption effect and stability during movement, counterweights can be set on the suction cups 220 to ensure that the suction cups 220 can accurately reach the required position and press against the glass plate to complete the adsorption and fixation.

[0021] The signal line and hose of the pressure sensor 230 are connected to the controller, which controls the weighing process based on the collected signals.

[0022] In one embodiment of this application, the vertical movement mechanism includes a vertical movement winch 210 and a pull rope 211. A pull frame 212 is fixed to the bottom of the pull rope 211, and a pressure sensor 230 is disposed on the pull frame 212. A horizontal plate 221 on the top of the suction cup 220 is placed on the pressure sensor 230. The position of the suction cup 220 is controlled by controlling the forward and reverse rotation of the winch, thereby completing actions such as adsorption, lifting, weighing, and lowering of the glass plate.

[0023] In one embodiment of this application, a traversing mechanism is further included. This traversing mechanism moves along a track 310 arranged above the conveyor roller conveyor, the track 310 being aligned with the arrangement direction of the conveyor roller conveyor. After the glass plate is lifted, the traversing mechanism moves the glass plate to the next position for weighing, avoiding glass plate accumulation and improving the efficiency of the glass plate weighing operation.

[0024] In one embodiment of this application, the conveyor roller conveyor includes an incoming material area 110 and a feeding area 120, and a stop block 111 is provided at the end of the incoming material area 110. The stop block 111 can block unweighed glass plates, preventing them from reaching the feeding area 120 without being weighed, and ensuring that they can only reach the feeding area 120 through the transport of this system.

[0025] In one embodiment of this application, the traversing mechanism includes support wheels 322 and a drive motor 321, wherein the drive motor 321 is drively connected to at least one of the support wheels 322; the track 310 has an I-shaped structure, and the support wheels 322 are supported on both sides of the track 310. The rotation of the drive motor 321 can drive the support wheels 322 to rotate, thereby causing them to move back and forth on the track 310; the I-shaped structure of the track 310 can prevent the traversing mechanism from derailing.

[0026] In one embodiment of this application, baffles 240 are provided on the front and rear sides of the weighing mechanism 200, and the bottom opening of the baffles 240 is not less than the length of the glass plate. During the forward and backward movement, the baffles 240 can prevent the glass plate from tilting too much due to inertia, thereby preventing it from shaking and affecting safety.

[0027] In one embodiment of this application, the baffle 240 is a downward-facing flared shape, and the suction cup 220 is located at the center of the baffle 240. The flared shape can guide the glass plate as it rises, preventing damage to the front and rear ends of the glass plate. Furthermore, the flared shape can accommodate glass plates of various sizes, enhancing its protective function.

[0028] According to this embodiment, the beneficial effect of using the glass plate in-line weighing system of this application is that the glass plate is lifted up and weighed, which ensures the efficiency of weight detection and does not affect the measurement accuracy due to dust, debris, etc., nor is it affected by the rotation vibration of the roller conveyor.
