Description

Technical Field

[0001] This utility model relates to the field of glass processing and conveying equipment technology, and in particular to a conveying table for assisting in the loading and unloading of glass. Background Technology

[0002] Tempered glass, due to its high strength and safety, is widely used in building curtain walls, appliance panels, and automotive glass. A typical tempered glass production line includes a loading table, a heating furnace, an air duct section, and a unloading table. The glass is conveyed to the heating furnace via the loading table and heated to the set temperature. Then, it enters the air duct section for quenching and tempering, and finally, it is unloaded via the unloading table.

[0003] Currently, in the glass loading process, glass that has been manually inspected for defects is usually placed on the loading roller conveyor. For smaller pieces of glass, a single person can handle the handling and transport; however, for larger pieces of glass, multiple people are required to lift and transport them to the roller conveyor, which is not only labor-intensive and inefficient, but also prone to glass breakage or personal injury accidents due to improper operation.

[0004] Therefore, there is an urgent need for an auxiliary conveying device that can reduce labor intensity, improve operational safety, and adapt to the loading and unloading of glass sheets of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a conveyor platform for assisting in the loading and unloading of glass, so as to solve the technical problems of high labor intensity and safety risks in the manual handling of large-size glass in the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a conveyor table for assisting in the loading and unloading of glass, including a frame and a roller conveyor assembly mounted on the frame; it also includes an auxiliary unloading device, which is fixedly installed at the end of the frame and includes a support base, a linear drive mechanism, and a free roller; there are two support bases, which are symmetrically fixed to the side of the frame; there are two linear drive mechanisms, which are respectively mounted on the support bases, and the telescopic rods of the linear drive mechanisms are obliquely upward; the free rollers are parallel to the roller conveyor of the roller conveyor assembly and are of similar length, and the two ends of the free rollers are connected to the free ends of the extension rods of the two linear drive mechanisms through spherical bearings; the telescopic rods of the linear drive mechanisms extend and retract to drive the free rollers to move up and down, assisting in the transfer of glass between the conveyor table and the external glass frame; the auxiliary unloading device also includes a control mechanism for controlling the extension and retraction of the linear drive mechanisms.

[0007] Furthermore, the tilt angle of the linear drive mechanism is adjustable to accommodate glass shelves of different heights and positions.

[0008] Furthermore, the linear drive mechanism is one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0009] Furthermore, the free roller is a rotatable rubber roller.

[0010] Furthermore, the joint bearing is equipped with a sliding component inside, which can adaptively adjust the height difference between the two ends of the free roller.

[0011] Furthermore, it also includes a universal table lifting device, which is fixedly installed on the frame and located below the roller conveyor assembly, for lifting the glass and moving and positioning the glass on the universal wheels.

[0012] Based on the above technical solution, the beneficial effects of this utility model are: 1. This utility model, by setting up an auxiliary unloading device, realizes the mechanical acceptance and transfer of large-size glass, significantly reduces the labor intensity of manual handling, improves operational safety, and effectively avoids glass breakage and personal injury accidents.

[0013] 2. This utility model features a flexible structural design. The auxiliary unloading device can be installed at the end or side of the conveyor table according to actual production needs, adapting to various loading and unloading scenarios. It is highly versatile and easy to modify and apply in existing production lines. In addition, the overall structure control system is simple, reliable, and easy to operate, which not only reduces the physical burden on operators but also effectively improves the production efficiency of the glass loading and unloading process and the stability of the overall process.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] The structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0018] like Figure 1-4 As shown, a conveyor table for assisting in the loading and unloading of glass includes a frame 1, a roller conveyor assembly 3 mounted on the frame 1, and an auxiliary unloading device 4.

[0019] The auxiliary unloading device 4 is fixedly installed at the end of the frame 1, and includes a support base 41, a linear drive mechanism 42, a free roller 43, and a control mechanism. There are two support bases 41, which are symmetrically fixed to the side of the frame 1. There are also two linear drive mechanisms 42, which are respectively installed on the support bases 41. The telescopic rods of the linear drive mechanisms 42 are set obliquely upward. Since there are slots on the support bases for limiting, the tilt angle of the linear drive mechanisms 42 can be manually adjusted to adapt to glass racks 7 of different heights and positions.

[0020] The free roller 43 is parallel to and of similar length to the roller conveyor of the roller conveyor assembly. Both ends of the free roller 43 are connected to the free ends of the extension rods of the two linear drive mechanisms 42 via spherical bearings. The spherical bearings have sliding components inside; specifically, the inner spherical surface of the outer ring of the spherical bearing has grooves and is fitted with self-lubricating pads to further optimize sliding performance and adaptively adjust the height difference between the two ends of the free roller 43 to prevent jamming. The telescopic rods of the linear drive mechanism 42 extend and retract to drive the free roller 43 in lifting and lowering motion, assisting in the transfer of glass between the conveyor table and the external glass frame 7. Specifically, the free roller 43 is a rotatable rubber roller. The linear drive mechanism 42 is one of a pneumatic cylinder, hydraulic cylinder, or electric cylinder, and its extension and retraction actions are controlled by a control mechanism.

[0021] The conveyor also includes a universal table lifting device 2, which is fixedly installed on the frame 1 and located below the roller conveyor assembly 3. It is used to lift the glass and move and position the glass on the universal wheels to achieve the purpose of straightening the glass.

[0022] This invention, by setting up an auxiliary unloading device, realizes the mechanical acceptance and transfer of large-sized glass, significantly reducing the labor intensity of manual handling, improving operational safety, and effectively avoiding glass breakage and personal injury accidents.

[0023] In specific implementation, the linear drive mechanism 42 is exemplified by a cylinder. During the loading process, after the operator has inspected the glass to be loaded 5, the solenoid valve is first opened, causing the cylinder rod to extend. Subsequently, the operator removes the glass to be loaded 5 from the glass stack 6 on the glass rack 7, flipping it from its angled position against the glass rack 7 to its position against the free roller 43 of the auxiliary unloading device 4. Then, the solenoid valve is closed, the cylinder rod retracts, and the glass to be loaded 5 contacts the roller conveyor of the conveyor table as the cylinder rod retracts. At this point, the operator lifts the glass to be loaded 5 and places it entirely on the roller conveyor. The glass to be loaded 5 then moves horizontally along the conveyor table roller conveyor for the next process.

[0024] During the unloading process, the tempered glass needs to move horizontally along the conveyor rollers. When one end of the glass touches the bottom of the glass holder 7, the operator opens the solenoid valve, and the cylinder rod slowly extends, lifting the glass and gradually raising its bottom. After the cylinder rod extends to its maximum position, the operator flips the glass onto the glass holder 7 to complete the unloading process.

[0025] This utility model features a flexible structural design. The auxiliary unloading device can be installed at the end or side of the conveyor table according to actual production needs, adapting to various loading and unloading scenarios. It is highly versatile and easy to modify and apply in existing production lines. In addition, the overall structural control system is simple, reliable, and easy to operate, which not only reduces the physical burden on operators but also effectively improves the production efficiency of the glass loading and unloading process and the stability of the overall process.

[0026] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
