Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass manufacturing technology, specifically to an annealing roller conveyor system for glass production. Background Technology
[0002] The production process of float glass involves transporting the glass, after it has been formed in a tin bath, to the cutting area via a stable annealing roller conveyor system. A traditional annealing roller conveyor system consists of an electrically connected roller conveyor structure, a frequency converter, and a motor. The roller conveyor structure comprises several rotatable transverse rollers fixed at intervals, forming a glass conveying platform. The rotation of the transverse rollers drives the glass conveying process. In operation, the frequency converter is manually set using acceleration / deceleration buttons on the roller conveyor operating platform. The motor speed is displayed on a digital display connected to the frequency converter, thus indirectly determining the operating speed of the roller conveyor structure.
[0003] However, in actual operation of annealing roller conveyors, problems frequently arise such as roller conveyor obstruction, transmission shaft misalignment, and bearing damage, leading to uneven roller conveyor speeds, glass breakage, and narrowing of the plate width. This results in significant economic losses and operational pressure. When these problems occur, the actual linear speed of the roller conveyor fluctuates or even becomes zero. Meanwhile, the motor continues to rotate according to the preset speed, making it impossible to monitor the linear speed of the roller conveyor in real time using the motor speed. Utility Model Content
[0004] The purpose of this invention is to address the problem that existing glass production annealing roller conveyor systems cannot monitor the linear speed of the roller conveyor structure in real time. This invention provides a glass production annealing roller conveyor system that achieves real-time monitoring of the roller conveyor structure's operating speed through the cooperation of the roller conveyor structure, encoder, and linear speed controller. This avoids production disruptions caused by undetected speed fluctuations, and the system is simple in structure and easy to control.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Roller conveyor structure;
[0008] An encoder is a device in which the rotor of an encoder is coaxially rotatably connected to a transverse roller in a roller conveyor structure. The encoder is used to convert rotational pulse signals into electrical signals.

[0014] In some embodiments, the end of the fixed support segment away from the elastic connecting shaft segment includes a sleeve structure, which is sleeved on the outside of the transverse roller and fixedly connected.
[0015] As a preferred embodiment of this utility model, it also includes a buzzer, which is electrically connected to the linear velocity controller. When the linear velocity controller displays that the linear velocity fluctuates or is about to reach zero, the buzzer is used for alarm indication.

Example
[0030] Currently, commonly used annealing roller conveyor systems consist of an electrically connected roller conveyor structure, a frequency converter, and a motor. The roller conveyor structure comprises several rotatable transverse rollers fixed at intervals, forming a glass conveying platform. The rotation of the transverse rollers drives the glass conveying process. During operation, the frequency converter is manually set via acceleration / deceleration buttons on the roller conveyor operating platform. The motor speed is displayed on a digital display connected to the frequency converter, indirectly indicating the operating speed of the roller conveyor structure. However, in actual operation, annealing roller conveyors frequently experience uneven speeds due to roller conveyor obstruction, transmission shaft misalignment, and roller bearing damage, leading to glass breakage and narrowing of the sheet width, resulting in significant economic losses and operational pressure. When these problems occur, the actual linear speed of the roller conveyor fluctuates or even becomes zero, while the motor speed continues to rotate according to the preset speed, making it impossible to monitor the linear speed of the roller conveyor structure in real time using the motor speed.
[0031] Therefore, as Figure 1 As shown, this embodiment provides an annealing roller conveyor system for glass production, including...
[0032] Roller conveyor structure;
[0033] Encoder 1, the rotor of encoder 1 is coaxially rotatably connected to a transverse roller 2 in the roller conveyor structure, encoder 1 is used to convert rotation pulse signal into electrical signal;
[0034] Linear speed controller 3 is electrically connected to encoder 1. Linear speed controller 3 is used to receive electrical signals from encoder 1 and convert the electrical signals into linear speed values of the roller conveyor structure for display.
[0035] In use, encoder 1 converts rotational pulse signals into electrical signals, and linear speed controller 3 converts the received electrical signals from encoder 1 into the linear speed value of the roller conveyor structure for display. This structure achieves real-time monitoring of the roller conveyor structure's operating speed through the cooperation of the roller conveyor structure, encoder 1, and linear speed controller 3, avoiding production disruptions caused by undetected speed fluctuations. It features a simple structure and is easy to control.
[0036] Specifically, the roller conveyor structure includes several rotatable transverse rollers fixed at intervals. When the roller conveyor is running, all the transverse rollers 2 rotate simultaneously at the same linear speed, and the glass placed on the platform formed by all the transverse rollers can move forward as the transverse rollers 2 rotate.
[0037] In one or more embodiments, a connecting shaft 4 is also included.
[0038] The connecting shaft 4 includes an elastic connecting shaft section 41 and a fixed support section 42 fixedly connected to the elastic connecting shaft 4. The end of the elastic connecting shaft section 41 away from the fixed support section 42 is fixedly connected to the rotor; the end of the fixed support section 42 away from the elastic connecting shaft section 41 is fixedly connected to the transverse roller 2. The section closer to the rotor is set as the elastic connecting shaft section 41, which can alleviate the vibration under high-speed rotation to a certain extent, making the structure more stable in operation.
[0039] In some embodiments, the encoder 1 is fixed using an encoder 1 mounting bracket. One end of the mounting bracket can be fixed by drilling a hole in the encoder 1's built-in screw hole, and the other end is fixed by drilling a hole in the bearing hanger seat, ensuring that the non-rotating shaft part of the encoder 1 is firmly fixed and does not shift. Through the above optimization, the encoder 1 and the annealing roller are guaranteed to have high coaxial accuracy, small error, and flexible rotation.
[0040] In some embodiments, the elastic connecting shaft segment 41 is an elastic steel structure, such as a spring-like structure.
[0041] In some embodiments, the end of the fixed bracket section 42 away from the elastic connecting shaft section 41 includes a sleeve structure 421, which is sleeved on the outside of the transverse roller 2 and fixedly connected. In some embodiments, the fixed bracket section 42 is in the form of two cylinders with different diameters (total length approximately 60mm). One end is machined into an inner hole with a diameter consistent with the outer diameter of the end of the transverse roller 2, an inner hole depth of approximately 20mm, and a wall thickness of approximately 10mm. Multiple (3 or more) threaded through holes are machined on the bracket to facilitate fixed connection with the screws at the end of the transverse roller 2. The other end is machined with an outer diameter consistent with the inner hole size of the elastic connecting shaft section 41 to fix the elastic connecting shaft section 41.
[0042] In some embodiments, a buzzer 31 is also included, which is electrically connected to the linear velocity controller 3. When the linear velocity controller 3 displays that the linear velocity fluctuates or is about to reach zero, the buzzer 31 is used to provide an alarm.
[0043] In some embodiments, the encoder 1 is an incremental rotary encoder 1. The incremental rotary encoder 1 is easy to install and has low cost.
[0044] In some embodiments, the linear velocity controller 3 includes a display panel for displaying preset linear velocity values and measured linear velocity values. Specifically, the linear velocity controller 3 may be equipped with an electronic linear velocity display meter (including a distribution box) with a 4-20mA analog input and the ability to receive pulse signals from the encoder 1.
[0045] In some embodiments, a DCS system 32 is also included, which is electrically connected to the linear speed controller 3. The real-time speed signal data of the roller conveyor is transmitted to the DCS system 32 in the central control room for remote monitoring. Specifically, the 4-20mA signal emitted by the linear speed controller 3 is introduced into the existing DCS system 32, and the speed curve is set through the host computer. The real-time speed curve is displayed on the process interface, which facilitates real-time monitoring by operators and allows maintenance personnel to conduct fault diagnosis and handling based on historical speed curves.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
