Description

Technical Field

[0001] The invention relates to the field of glass manufacturing, and in particular to a manufacturing device and method for a glass conveying roller. Background Art

[0002] With the rapid development of the glass manufacturing industry, the glass conveyor roller head is a key component, and the optimization and improvement of its manufacturing process method are of great significance to improving glass production efficiency, reducing production costs and improving product quality.

[0003] The conveyor roller is one of the important parts of the glass production line. It is the carrier in the glass forming process. Its production batch is large and it is a part that urgently needs to improve production efficiency. The shaft head of the glass conveyor roller is used on the glass conveyor roller. There are a large number of them on each production line with a certain batch. After the shaft head is welded, it needs to be transferred to the subsequent process. The production cycle is long. Therefore, the welding of the shaft head is a part that urgently needs to improve manufacturing efficiency in the glass production process.

[0004] The shaft head of the glass conveyor roller is thin at the top and thick at the bottom, similar to a pagoda-shaped structure. When manufacturing its blank, in order to save materials, a steel shaft ring is often used to weld the round steel shaft body. The existing welding method of the shaft ring and the shaft body is the traditional manual mode, that is, the worker holds the welding gun to weld. Since the weld between the shaft ring and the shaft body is a circular ring, the worker often needs to rotate the workpiece during welding, and control the welding gun by the wrist to weld. This welding method is time-consuming and labor-intensive. Only about 80 pieces can be welded in one shift, with low production efficiency and unstable welding quality, which affects the overall performance and service life of the shaft head. In addition, manual welding has high intensity, complex welding environment, and great harm to welders. The welding dust and gas generated cannot be handled uniformly, and the welding arc also causes harm to the surrounding working environment.

[0005] At the same time, the existing method for making glass conveyor rollers is to first weld the steel roller to the shaft head, and then perform metal processing on a lathe. For example, the patent document with publication number CN103350878A discloses a large heat-resistant conveyor roller, including a hollow roller body, shaft heads are arranged at both ends of the hollow roller body, the hollow roller body is connected to a connector through a flange, and the hollow roller body, flange, connector and shaft head are welded together. Due to the uneven distribution of temperature during welding, residual stress will be generated, which is easy to cause material deformation, affecting the assembly accuracy between the steel roller and the shaft head and the use effect of the conveyor roller; welding requires waiting for the weld to cool and solidify, the production cycle is long, and the production efficiency is low; harmful gases and smoke may be generated during welding, causing environmental pollution; and the welding process requires operators to hold certificates before taking up their posts, which has high labor costs. Summary of the invention

[0006] The technical problem to be solved by the present invention is how to reduce material deformation when manufacturing a glass conveying roller, improve the assembly accuracy between the roller and the shaft head and the use effect of the conveying roller.

[0007] The present invention solves the above-mentioned technical problems through the following technical means: a manufacturing device for a glass conveyor roller, comprising a shaft head welding device and a heat-loading device; the shaft head welding device is used to weld the shaft head; the heat-loading device comprises a loading rack, a loading mechanism, a heating mechanism, a unloading mechanism, an unloading rack and an operating table; the loading rack is used to place the roller, the loading mechanism is used to transfer the roller from the loading rack to the heating mechanism, the heating mechanism is used to heat the roller, the unloading mechanism is used to transfer the heat-loaded glass conveyor roller from the heating mechanism to the unloading rack, and the operating table is used to operate the loading mechanism, the heating mechanism and the unloading mechanism.

[0008] The device can position the shaft head to be welded with the front side facing upward or the back side facing upward through the table. When the shaft head is positioned with the front side facing upward, the welding robot can operate the welder to weld the front weld. When the shaft head is positioned with the back side facing upward, the welding robot can operate the welder to weld the back weld. The rotating mechanism drives the table to rotate and can move multiple shaft heads to the welding stations in sequence. The production efficiency is high, the welding quality is stable, and the overall performance and service life of the shaft head are improved.

[0009] The device can load, heat and unload the roller. After the roller is heated, the worker holds the shaft head and gently inserts it into the roller to complete the hot loading. Since the hot loading process expands the material by heating and then assembles it together, and the material shrinks and is tightly connected after cooling, the deformation caused by local high temperature during welding is reduced, and the assembly accuracy between the roller and the shaft head and the use effect of the conveyor roller are improved. The hot loading process does not need to wait for the weld to cool and solidify, shortens the production cycle and improves production efficiency. The hot loading process does not produce harmful gases and smoke, and usually uses less energy, which helps to reduce energy consumption and environmental pollution. The hot loading process does not require operators to be certified, which greatly reduces the total cost of production.

The second adjustment plate is fixedly connected to the third bracket; the height of the third bracket 91 can be adjusted through the second adjustment seat 95, thereby adjusting the height of the rolling rack 93 to make it better adapt to the height of the heating mechanism 8.

[0064] Working principle: When in use, firstly, the rollers 12 to be hot-loaded are hung in batches on the loading rack 6, so that multiple rollers 12 are arranged in a row front and back and placed on the loading rack 6; then the worker operates the operating table 11 to open the loading mechanism 7, and the gripper 78 grabs the first roller 12 on the loading rack 6 during the movement from bottom to top driven by the transmission bar 77. After the gripper 78 moves to the highest point, it turns to move from top to bottom, and its arc opening turns downward. The roller 12 falls off from the gripper 78 under the action of gravity and falls into the bracket 89; at this time, the heating mechanism 8 receives the instruction, and the piston rods of the two first cylinders 88 contract, pulling the two fixing frames 84 closer to each other, so that the two magnetic induction coils are respectively sleeved on the outside of the two ends of the roller 12 to heat the roller 12; after the set heating time is reached, the piston rods of the two first cylinders 88 extend, pushing the two fixing frames 84 away from each other, so that the two magnetic induction coils The coil is away from the roller 12 and the heating is stopped. At this time, the two ends of the roller 12 are in a state of thermal expansion. The worker holds the shaft head 5 and gently inserts it into the roller 12 to complete the hot loading. After the hot loading is completed, the worker operates the workbench 11, and the unloading mechanism 9 receives the command. The piston rods of the two second cylinders 94 contract, driving the rolling frame 93 to rotate counterclockwise, thereby increasing the angle between the rolling frame 93 and the horizontal plane. The rolling frame 93 lifts the roller 12 upward from the bottom of the roller 12 in the bracket 89 to separate it from the bracket 89, and then the roller 12 rolls down along the rolling frame 93 to the unloading frame 5; after the roller 12 rolls down, the unloading mechanism 9 receives the command, and the piston rods of the two second cylinders 94 extend, causing the rolling frame 93 to rotate clockwise, thereby reducing the angle between the rolling frame 93 and the horizontal plane, until the piston rods of the two second cylinders 94 are in a fully extended state. At this point, the hot loading of a glass conveying roller is completely completed.

After the gripper 78 moves to the highest point, it switches to move from top to bottom, and its arc opening turns downward. The roller 12 falls off from the gripper 78 under the action of gravity and falls into the bracket 89.

[0069] S4, the heating mechanism 8 receives the command, the piston rods of the two first cylinders 88 contract, and the two fixing frames 84 are pulled closer to each other, so that the two magnetic induction coils are respectively sleeved on the two ends of the roller 12 to heat the roller 12.

[0070] S5. After the set heating time is reached, the piston rods of the two first cylinders 88 extend out, pushing the two fixing frames 84 away from each other, so that the two magnetic induction coils are away from the roller 12, and the heating is stopped. At this time, both ends of the roller 12 are in a state of thermal expansion. The worker holds the shaft head 5 and gently inserts it into the roller 12 to complete the thermal installation.

[0071] S6. The worker operates the workbench 11, and the unloading mechanism 9 receives the command. The piston rods of the two second cylinders 94 contract, driving the rolling rack 93 to rotate counterclockwise. The rolling rack 93 lifts the roller 12 upward from the bottom of the roller 12 in the bracket 89 to separate it from the bracket 89, and then the roller 12 rolls down along the rolling rack 93 into the unloading rack 5.

[0072] S7, the unloading mechanism 9 receives the command, and the piston rods of the two second cylinders 94 extend, causing the rolling frame 93 to rotate clockwise until the piston rods of the two second cylinders 94 are in a fully extended state.
