Description

Technical Field

[0001] This utility model relates to the field of glass production and processing, and in particular to a device and a glass loading and unloading system for assisting in the loading and unloading of glass sheets. Background Technology

[0002] In the field of glass deep processing, especially in the architectural glass industry, glass products generally adopt a fully customized processing model. In the actual production process, there is a key step: the glass sheet needs to be smoothly laid down from the glass rack onto the upper stage of the processing equipment, and after the processing steps are completed, it is then uprighted back onto the glass rack from the lower stage of the processing equipment.

[0003] The transfer of glass slides between the glass rack and the upper and lower slide platforms mostly relies on manual handling. This is especially true for large glass slides, which, due to their size and weight, often require the coordinated efforts of multiple workers. When moving a glass slide from the glass rack to the upper and lower slide platforms, firstly, ensure the bottom of the slide remains supported by the glass rack and stationary. Then, slowly tilt the slide towards the side of the upper and lower slide platforms. Once tilted to the appropriate angle, multiple workers work together to lift the slide and place it smoothly on the upper and lower slide platforms. When moving a glass slide from the upper and lower slide platforms to the glass rack, multiple workers work together to lift the slide horizontally, then move the entire slide towards one side of the glass rack. Next, place the side of the slide closest to the rack onto the glass rack, tilting the slide, and finally adjust it to a vertical position.

[0004] However, in the actual process of handling glass, poor coordination and uncoordinated actions among personnel are very common. This lack of coordination not only leads to breakage of the glass during transport, wasting raw materials, but more seriously, broken glass can easily cause cuts, posing a serious threat to the lives of the operators. Utility Model Content

[0005] The purpose of this invention is to overcome the problem in the prior art where the transfer of glass between glass racks and loading / unloading platforms relies on manual handling, which is prone to glass breakage and cuts due to poor coordination among personnel. Therefore, this invention provides a device and system for assisting in the loading and unloading of glass sheets.

[0006] In a first aspect, the present invention provides a device for assisting in the mounting and dismounting of glass sheets, comprising: Two telescopic components are arranged side by side at an angle, and each telescopic component has a base at its bottom; each telescopic component includes a telescopic head; Two support components, the tops of which are respectively connected to the two telescopic components; The roller has its two ends connected to the telescopic heads of the two telescopic components, and the movement of the two telescopic heads can drive the roller to move away from or towards the telescopic component along the axial direction of the telescopic component.

[0007] The device is designed to be installed below the upper and lower film stages, and the roller needs to be located between the upper and lower film stages and the glass holder.

[0008] This invention provides a device for assisting in the loading and unloading of glass sheets. The telescopic component drives the telescopic head, thereby providing power for the movement of the roller. The telescopic component is arranged at an angle to ensure that the roller can move obliquely upwards or downwards. When the telescopic component extends, the roller moves obliquely upwards towards the glass frame; when the telescopic component retracts, the roller moves obliquely downwards towards the loading and unloading platform. When the glass sheet is transferred between the glass frame and the loading and unloading platform, this movement of the roller better conforms to the transfer trajectory of the glass sheet, thus providing stable and effective support for the glass sheet and assisting in the transfer process. The base is used to fix the bottom of the telescopic component to the ground, preventing the telescopic component from shaking or shifting during operation. The bottom of the support component is supported on the ground, and the top of the support component supports the telescopic component. The support component, the telescopic component, and the ground together form a stable triangular support structure, which can effectively distribute the force borne by the device during operation and ensure the stability of the entire device. The rollers are used to directly contact the glass sheet, serving to assist in supporting the glass sheet. During the glass sheet transfer process, the rollers can evenly distribute the weight of the glass sheet, preventing the glass sheet from breaking or being damaged due to excessive local stress.

[0009] This utility model provides a device for assisting in the loading and unloading of glass sheets. When the glass sheets are transferred between the glass frame and the loading and unloading platform, the device can provide auxiliary support for the glass sheets. Through the drive of the telescopic component, it can provide auxiliary support force for the glass sheets during the handling process, thereby reducing the force required for manual handling and greatly reducing the risk of glass breakage and cuts caused by improper operation during manual handling.

[0010] The base can be fixed to the ground, for example, the base can be a steel plate, the steel plate is connected to the ground by bolts, and the top surface of the steel plate is connected to the bottom of the telescopic component by welding; the base can also be connected to the ground by hinge.

[0011] Preferably, the base connects the bottom of the telescopic component to the ground via a hinge. This design ensures that after the bottom of the telescopic component is fixed to the ground and before the support component is installed, the angle between the telescopic component and the ground can be flexibly adjusted to ensure that the angle supporting the glass sheet is adjusted to the most suitable angle, thereby providing stable and reliable support for the glass sheet.

[0012] Preferably, the base includes a first ear seat and a second ear seat, which are connected by a pin. The first ear seat is used to connect to the ground, and the second ear seat is connected to the bottom of the telescopic component. In this design, the combined design of the first and second ear seats creates a hinged structure between the bottom of the telescopic component and the ground.

[0013] Preferably, the top of the supporting component and the top of the telescopic component are connected by a connecting plate. The connecting plate has a through hole through which the telescopic head passes. The top of the supporting component has a slope, and the connecting plate is connected to the slope. In this design, the connecting plate increases the connection area between the top of the supporting component and the top of the telescopic component, thereby enhancing the stability of the connection. The inclination angle of the slope matches the inclination angle of the connecting plate and the top of the telescopic component after they are fixed, thus reducing the welding gap between the top of the supporting component and the connecting plate and increasing the strength of the connection.

[0014] Preferably, the roller and the telescopic head are connected via a spherical bearing and a connector. The spherical bearing is connected to the end of the roller and includes a support arm. The two ends of the connector are respectively connected to the support arm and the telescopic head. In this configuration, the spherical bearing is used to connect to the end of the roller, and the connector serves to connect the support arm and the telescopic head.

[0015] Preferably, the roller includes two shaft ends, a steel pipe, and a buffer layer. The two shaft ends are respectively inserted into both ends of the steel pipe, and the buffer layer wraps around the outer wall of the steel pipe. In this design, the steel pipe serves as the skeleton structure of the roller, providing it with necessary strength and support. The two shaft ends are connected to both ends of the steel pipe and protrude from the ends of the steel pipe; these shaft ends are used to connect to the telescopic head. The buffer layer is made of a material with good cushioning properties and is used to directly contact the glass sheet. During the process of the roller supporting the glass sheet, the buffer layer can fully utilize its cushioning characteristics, effectively reducing the impact force caused by vibration, thereby significantly reducing the probability of the glass sheet breaking.

[0016] The telescopic component can be a hydraulic cylinder, a pneumatic cylinder, or a lead screw and nut telescopic mechanism.

[0017] Preferably, the telescopic component is a cylinder. Compared to a hydraulic cylinder, the cylinder has a more compact design, eliminates the need for hydraulic lines, reduces space requirements, and, being driven by compressed air, offers a faster response rate. In contrast, the screw-nut telescopic mechanism relies on a motor for rotational drive, resulting in longer acceleration and deceleration processes, making it difficult to achieve instantaneous start and stop with the cylinder.

[0018] The buffer layer can be made of materials such as rubber, polyurethane, or silicone.

[0019] Preferably, the buffer layer is made of EPDM rubber. In this embodiment, EPDM is called EthylenePropylene Diene Monomer, which is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene.

[0020] Preferably, the vulcanization hardness of the EPDM rubber is Shore 65-70.

[0021] In a second aspect, the present invention provides a glass loading and unloading system, including a glass frame, a loading and unloading platform, and a device for assisting in the loading and unloading of glass as described in the first aspect, wherein the device is located below the loading and unloading platform, and the roller of the device is located between the glass frame and the loading and unloading platform.

[0022] This invention provides a glass loading and unloading system, wherein the glass frame is used to hold glass sheets, and the loading and unloading platform is used to process the glass sheets. When the glass sheets are transferred between the glass frame and the loading and unloading platform, the device can provide auxiliary support force for the glass sheets during the handling process, thereby reducing the force required for manual handling and greatly reducing the risk of glass breakage, damage, and cuts caused by improper operation during manual handling.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a device for assisting in the loading and unloading of glass sheets. When the glass sheets are transferred between the glass frame and the loading and unloading platform, the device can provide auxiliary support for the glass sheets.

For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0056] Example 2 like Figure 10 As shown, a glass loading and unloading system includes a glass frame 9, a loading and unloading platform 8, and a device for assisting in loading and unloading glass as described in Embodiment 1.

[0057] like Figure 11 The diagram illustrates the different states of the glass loading and unloading system during the assisted handling of the glass sheet 10. Solid and dashed arrows indicate the sequence of state changes.

[0058] Move the glass slide 10 from the glass holder 9 to the upper and lower slide stage 8, as follows: Figure 11 As indicated by the solid arrow, the handling process is as follows: First, the telescopic component 1 is extended, causing the roller 6 to move obliquely upwards towards the glass holder 9. Once the roller 6 reaches the predetermined position, the telescopic component 1 stops moving. At this point, keeping the bottom of the glass sheet 10 in the same position on the glass holder 9, the top of the glass sheet 10 is manually rotated towards the roller 6, causing the glass sheet 10 to lean against the roller 6 at an angle. Next, the telescopic component 1 is retracted, causing the roller 6 to move obliquely downwards towards the upper and lower glass platforms 8. During this process, the glass sheet 10 gradually changes from vertical to tilted. When the roller 6 reaches the same height as the top surface of the upper and lower glass platforms 8, the telescopic component 1 stops moving. Then, the bottom of the glass sheet 10 is manually lifted, causing the glass sheet 10 to rotate around the axis of the roller 6, gradually adjusting it to a horizontal position. Finally, the horizontally positioned glass sheet 10 is moved horizontally onto the upper and lower glass platforms 8.

[0059] Move the glass slide 10 from the upper and lower slide table 8 to the glass holder 9, as follows: Figure 11 As indicated by the dashed arrow, the handling process is as follows: First, adjust the position of roller 6 so that it is at the same height as the top surface of the upper and lower glass trays 8. Next, move the glass sheet 10 as a whole towards the glass holder 9. When the middle position of the glass holder 9 is at roller 6, move the side of glass sheet 10 closest to the glass holder 9 downwards, causing glass sheet 10 to rotate around the axis of roller 6. Then, place the side of glass sheet 10 closest to the glass holder 9 onto the glass holder 9. Afterwards, control the extension of telescopic component 1 to extend, causing roller 6 to move obliquely upwards towards the glass holder 9. During this process, keep the bottom of glass sheet 10 in the same position on the glass holder 9, and under the push of roller 6, the glass sheet 10 gradually changes from tilted to vertical. Finally, manually bring the top of glass sheet 10 against the upright plate of the glass holder 9.

[0060] This utility model provides a device for assisting in the placement and erection of glass panes. By mechanically supporting the glass during its lowering or erection, personnel do not need to touch the glass, significantly reducing labor intensity and improving safety. The mechanism is simple in design, low in cost, easy to install, and requires no major modifications to existing equipment.

[0061] Automated glass loading tables can automate the loading and unloading of most glass products, significantly reducing labor intensity and safety risks. However, for some extra-large, irregularly shaped, or mismatched glass products, manual intervention or manual loading is still required. Furthermore, the equipment investment is relatively large. Linear automation allows for the continuous processing of products with fixed workflows, reducing loading and unloading steps. However, for some glass requiring special processing, separate equipment is still needed, necessitating loading and unloading operations. Linear automation requires a high investment and is suitable for large-scale glass processing.

[0062] The present invention provides a device for assisting in the loading and unloading of glass sheets, which can also make up for the shortcomings of the above-mentioned automated equipment, solve the problems of high labor intensity and high safety risks in glass handling that requires manual loading and unloading, and has low investment cost and can be easily added to the original equipment.

[0063] 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.
