Description

Technical Field

[0001] The invention belongs to the technical field of glass production, and in particular relates to a loading trolley and a laminated glass production line. Background Art

[0002] Laminated glass is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer interlayer in between. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processing, the glass and the interlayer are permanently bonded together. The production process of laminated glass generally includes peeling and cutting, laminating, exhausting and high-pressure molding. Among them, high-pressure molding in an autoclave is a relatively critical step, which is related to whether the two layers of laminated glass can be permanently bonded together.

[0003] Autoclave high-pressure heating molding usually refers to placing the assembled glass on a loading trolley and then placing the glass in an autoclave for processing. The existing glass loading trolleys are prone to tilting and instability due to the lack of effective fixation when loading glass, and the safety of glass transportation cannot be guaranteed; in addition, after the glass is heated, it needs to be moved from the loading trolley to the next operating station and unloaded. When the glass on one side of the glass loading trolley is moved, it is necessary to use a forklift to lift the glass loading trolley and turn it so that the glass on the other side of the glass loading trolley can be directed toward the operating station for unloading. The unloading efficiency is low, which affects the production efficiency of laminated glass. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] See also Figures 1 to 4The embodiment of the present application provides a loading trolley for moving the sheet material to the unloading area. It can be understood that the sheet material can be a laminated glass sheet, and the unloading area is used to unload the sheet material on the loading trolley. Of course, in other possible embodiments, the sheet material can also be a plate-shaped material such as a wooden board, a stainless steel board or a plastic board.

[0029] Furthermore, if Figure 1 As shown, the loading trolley includes a supporting base 10, a loading bracket 20 connected to the supporting base 10 and rotating around a rotation axis a, and a fixing component 30 connected to the loading bracket 20. Sheet material placement positions 200 are provided on both sides of the loading bracket 20. Multiple sheets are placed in each sheet material placement position 200. The fixing component 30 is used to fix the sheets. The loading bracket 20 can be driven to rotate by an external force so that each sheet material placement position 200 can be at least partially located in the unloading area.

[0030] The loading trolley provided by the present application can fix the sheet material on the sheet material placement position 200 by the fixing assembly 30, so that the sheet material can be stably loaded on the loading trolley, thereby improving the stability of the loading trolley and the reliability of loading the sheet material. In addition, by rotatably connecting the loading bracket 20 with the support base 10, the loading bracket 20 can be driven to rotate by an external force, so that the multiple sheet material placement positions 200 on the loading bracket 20 can be partially or completely located in the unloading area in sequence for unloading, thereby improving the unloading efficiency of the loading trolley.

[0031] It can be understood that the rotation axis a can be located at the center of the loading bracket, and two sheet placement positions 200 are formed on both sides of the loading bracket 20 with the plane passing through the rotation axis a as the boundary. The unloading area can cover the area on one side of the loading bracket 20 so that the sheet placement position 200 is completely located in the unloading area, and the unloading area can also partially overlap with the area on one side of the loading bracket 20 so that the sheet placement position 200 is partially located in the unloading area.

[0032] In some embodiments, Figure 2 As shown, the top surface of the loading bracket 20 is connected with a first rotating connection member 41, and the surface of the loading bracket 20 facing the support base 10 is connected with a second rotating connection member 42, and the second rotating connection member 42 is rotatably connected to the first rotating connection member 41. It can be understood that the loading bracket 20 is arranged above the support base 10, and the first rotating connection member 41 is arranged on the top surface of the support base 10, and the second rotating connection member 42 is arranged on the bottom surface of the loading bracket 20, which can ensure that the loading bracket 20 and the loading bracket 20 rotate relatively smoothly.

[0033] In some embodiments, the first rotating connector 41 and the second rotating connector 42 are both annular structures. The first rotating connector 41 is sleeved outside the second rotating connector 42. The first rotating connector 41 and the second rotating connector 42 have a gap along the radial direction, and a rolling element 43 is arranged in the gap.

[0034] It can be understood that the axes of the first rotating connection member 41 and the second rotating connection member 42 are both coaxially arranged with the rotation axis a, the first rotating connection member 41 and the second rotating connection member 42 are concentrically arranged, and the radius of the first rotating connection member 41 is larger than the radius of the second rotating connection member 42. Therefore, the cross-sectional area of ​​the first rotating connection member 41 is larger than the cross-sectional area of ​​the second rotating connection member 42, which can ensure that there is a radial gap between the second rotating connection member 42 and the first rotating connection member 41.

[0035] Moreover, since the loading bracket 20 is arranged at the bottom of the supporting base 10, the first rotating connector 41 actually also supports the loading bracket 20. Therefore, the radius of the first rotating connector 41 is greater than the radius of the second rotating connector 42, which can ensure that the span range of the first rotating connector 41 is larger, thereby providing a better supporting effect on the loading bracket 20, making the loading bracket 20 more stable, and further ensuring the safety and stability of glass transportation. Of course, in other possible implementations, the second rotating connector 42 can also be sleeved outside the first rotating connector 41, that is, the radius of the second rotating connector 42 is greater than the radius of the first rotating connector 41, so the cross-sectional area of ​​the second rotating connector 42 is greater than the cross-sectional area of ​​the first rotating connector 41.

[0036] It can be understood that when the first rotating connector 41 and the second rotating connector 42 rotate relative to each other, the first rotating connector 41 is stationary, and the second rotating connector 42 rotates with the loading bracket 20, and because the gap between the first rotating connector 41 and the second rotating connector 42 is provided with a rolling element 43, that is, the first rotating connector 41 and the second rotating connector 42 are connected by a bearing, which can reduce friction, make the rotation more stable, reduce energy consumption, improve rotation accuracy, ensure the accuracy and stability of the machine, reduce friction and heat, and thus reduce energy loss. Specifically, the rolling element 43 can be a ball or a roller, etc., and the present application does not limit the specific structure of the rolling element 43.

[0037] In some embodiments, the loading bracket 20 includes a vertical rod 21 extending in the vertical direction and a plurality of cross rods 22 connected to the vertical rod 21 and extending in the horizontal direction. The plurality of cross rods 22 are arranged at intervals in the vertical direction. Each sheet material is placed between two adjacent cross rods 22 in the vertical direction. The fixing assembly 30 is connected to the cross rod 22.

[0038] It can be understood that when a single cross bar 22 is connected to the vertical bar 21 , the single cross bar 22 is separated by the vertical bar 21 , and both sides of the single cross bar 22 can be used to place sheet materials, thus forming two sheet material placement positions 200 on both sides of the single cross bar 22 .

[0039] In some embodiments, multiple cross bars 22 can be connected to the same height of the vertical rod 21, and the multiple cross bars 22 can cross each other, so as to form multiple sheet material placement positions 200 distributed along the circumference of the loading bracket 20, thereby increasing the number of sheets placed on the loading trolley and improving the loading rate of the loading trolley.

[0040] In addition, since multiple cross bars 22 are arranged at intervals in the vertical direction, the loading bracket 20 is equivalent to a multi-layer structure, which can form multiple sheet placement positions 200 arranged in the vertical direction, thereby increasing the number of sheets placed on the loading trolley and improving the loading rate of the loading trolley.

[0041] It can be understood that when the sheet material is placed between two adjacent cross bars 22 , the two ends of the sheet material abut against the upper and lower cross bars 22 respectively, so that the placement state of the sheet material is stable.

[0042] Furthermore, a sleeve pad 23 can be set on the outside of the cross bar 22. The sleeve pad 23 is made of soft material, such as silicone, rubber, and sponge. Therefore, when it comes into contact with the sheet material, the sleeve pad 23 can play a protective role to prevent the cross bar 22 from making hard contact with the sheet material, thereby reducing the damage rate of the sheet material.

[0043] In some embodiments, Figure 4 As shown, the fixing assembly 30 includes a cantilever 31 connected to the cross bar 22 and a plurality of spacer baffles 32 connected to the cantilever 31 . The cantilever 31 is arranged parallel to the cross bar 22 . The plurality of spacer baffles 32 are arranged at intervals along the extension direction of the cantilever 31 . The sheet material is clamped between two adjacent spacer baffles 32 .

[0044] By setting up the fixing component 30 and using the spacer baffles 32 to isolate the plate materials, it can ensure that the plate materials are firmly fixed and prevent the plate materials from falling over. At the same time, the distance between the spacer baffles 32 can be flexibly set. For example, the distance between two adjacent spacer baffles 32 can be set to be equal. When the plate material is laminated glass, the same spacing distance can be ensured between the glasses, thereby improving the high-pressure finished product rate of laminated glass.

[0045] In addition, a plurality of spacer baffles 32 are provided on the cantilever 31. The spacer baffles 32 can be set to be thin sheets. The plates are isolated by the thinner spacer baffles 32, which can increase the number of plates placed on the loading trolley and improve the loading rate of the loading trolley, thereby reducing the number of times the loading trolley is used and improving production efficiency.

[0046] In addition, the spacer baffle 32 can be made of stainless steel. The stainless steel spacer baffle 32 will not absorb too much heat in the autoclave. The autoclave has a better heating effect on the glass, which has a significant effect on energy saving and consumption reduction. The structure is stable and reliable, and there is no risk of falling off.

[0047] In some embodiments, a protective cover is provided at one end of the spacer baffle 32 away from the cantilever 31, and the protective cover is made of a soft material. By providing the protective cover, and the protective cover is made of a soft material, when in contact with the sheet material, the protective cover can play a protective role, avoiding the spacer baffle 32 from hard contact with the sheet material, thereby reducing the damage rate of the sheet material. Optionally, the protective cover is made of materials such as silicone, rubber, and sponge.

[0048] In some embodiments, a connection hole is provided at one end of the spacer baffle 32 , and the spacer baffle 32 is sleeved on the cantilever 31 through the connection hole. The spacer baffle 32 is a strip-shaped structure and extends in the vertical direction.

[0049] By providing the connection hole, the spacer baffle 32 is sleeved on the cantilever 31 through the connection hole, so that the connection between the spacer baffle 32 and the cantilever 31 is stable and reliable, and the safety performance is improved. In addition, the spacer baffle 32 is a strip structure and the spacer baffle 32 extends in the vertical direction, which can increase the length of the spacer baffle 32 in the vertical direction, so that the contact area between the spacer baffle 32 and the plate material is larger, and the stability of the plate material placement is further ensured.

[0050] In some embodiments, a stop rod 33 can also be set at the end of the cantilever 31. One end of the stop rod 33 is connected to the cantilever 31, and the other end extends downward. The length of the stop rod 33 is greater than the length of the spacer baffle 32, so it can play a role in resisting the sheet material and preventing the sheet material from tipping to both sides.

[0051] In some embodiments, the vertical rod 21 is provided with a plurality of connection holes 211 at different heights, and the cross rod 22 can be connected to different heights of the vertical rod 21 through each connection hole 211, and a telescopic support rod 24 is connected between two adjacent cross rods 22, and the length of the telescopic support rod 24 can be adjusted to change the height of the cross rod 22.

[0052] By adjusting the height of the crossbar 22, the height of the spacing baffle 32 is synchronously adjusted, so that plates of different heights can be used, thereby improving the applicability and flexibility of the loading trolley of the present application.

[0053] In some embodiments, Figure 3As shown, the telescopic support rod 24 may include a fixed rod 241 connected to the cross bar 22 and extending in the vertical direction, and a sleeve 242 sleeved outside the fixed rod 241. The fixed rod 241 is slidably connected to the sleeve 242, and the fixed rod 241 can slide along the length direction of the sleeve 242. Further, in order to improve the stability of the telescopic support rod 24 during use and prevent it from loosening, falling off or tilting due to external forces, a plurality of limiting holes 2411 cooperating with the fixing member are formed on the fixed rod 241. The plurality of limiting holes 2411 are arranged at intervals along the length direction of the fixed rod 241. The fixed rod 241 can be locked on the sleeve 242 through the limiting holes 2411 and the fixing member. Specifically, the fixing member is a limiting bolt and a nut. Of course, the fixing member can also be a limiting pin and an elastic protruding column.

[0054] In some embodiments, the distance between two adjacent limiting holes 2411 on the fixing rod 241 along the length direction of the fixing rod 241 is equal; of course, in other possible embodiments, the distance between two adjacent limiting holes 2411 on the fixing rod 241 is arranged in an arithmetic progression or a geometric progression along the length direction of the fixing rod 241, so that it can be quickly adjusted according to different sheet material heights, thereby improving the adaptability of the telescopic support rod 24.

[0055] In addition, two telescopic support rods 24 can be connected between two adjacent cross bars 22, and the two telescopic support rods 24 are located at both ends of the two cross bars 22, which is equivalent to the two cross bars 22 and the two telescopic support rods 24 being surrounded to form a frame structure, and the sheet material is placed in the frame structure, thereby further improving the stability of the sheet material placement.

[0056] In some embodiments, a locking member 50 is further disposed between the support base 10 and the loading bracket 20 , and the locking member 50 has a first state of unlocking the support base 10 and the loading bracket 20 and a second state of locking the support base 10 and the loading bracket 20 .

[0057] When a sheet placement position 200 on the loading bracket 20 rotates to a preset position, the support base 10 and the loading bracket 20 can be locked by the locking member 50, so that the loading bracket 20 no longer slides, and the support base 10 and the loading bracket 20 remain stationary, which is convenient for carrying the sheet on the loading trolley. It can be understood that the locking member 50 can also unlock the support base 10 and the loading bracket 20. When the orientation of the sheet placement position 200 needs to be adjusted, the support base 10 and the loading bracket 20 are locked by the locking member 50, so that the loading bracket 20 can resume the free rotation state.

[0058] The present application also proposes a laminated glass production line, which includes a loading trolley. The specific structure of the loading trolley refers to the above-mentioned embodiment. Since the laminated glass production line adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0059] In summary, the loading trolley provided by the present application can fix the sheet material on the sheet material placement position 200 by the fixing assembly 30, so that the sheet material can be stably loaded on the loading trolley, thereby improving the stability of the loading trolley and the reliability of loading the sheet material. In addition, by rotatably connecting the loading bracket 20 with the support base 10, the loading bracket 20 can be driven to rotate by an external force, so that the multiple sheet material placement positions 200 on the loading bracket 20 can be partially or completely located in the unloading area in sequence for unloading, thereby improving the unloading efficiency of the loading trolley.

[0060] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
