Description

Technical Field

[0001] This invention relates to the field of glass panel lifting and conveying technology, specifically to a lifting machine for opening mold materials and vertically transporting glass panel cassettes. Background Technology

[0002] In the field of glass panel manufacturing and handling, elevators for vertically transporting glass panel cassettes across floors are a crucial component of automated material handling systems (AMHS). As glass panels become increasingly thinner, their brittleness and fragility pose significant challenges to vertical transport across floors. Due to the fragility and vibration sensitivity of glass panels, ensuring stable transport of the glass panels within the cassettes is essential during lifting. Existing elevators typically employ steel guide rails for transporting glass panel cassettes, with car rollers moving along channel steel guide rails. The large gap between the rollers and the steel guide rails results in high noise levels, unstable transport, and a high risk of glass panel breakage. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting mechanism for opening mold materials and vertically transporting glass panel cassettes, aiming to provide a lifting and transport solution with high stability and low vibration matching the glass panels.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The first aspect of the present invention provides an open-form profile for an elevator, comprising a face profile and a leg profile. The face profile has a first surface G and a second surface. The first surface G is configured with a counterweight connecting portion for connecting a counterweight mounting rail of the elevator. The counterweight connecting portion is configured as a concave groove arranged along the length direction of the face profile. The leg profile is fixedly connected to the first surface G along the length direction of the face profile. The leg profile also has a first surface F and a second surface. The counterweight connecting portion corresponds to the second surface of the leg profile. The first surface F has slots distributed along the length direction for mounting the lifting guide rail of the elevator.

[0006] In a preferred embodiment, the slot is used to insert a mounting plate that mates with the lifting guide rail, and the inner and outer surfaces of the slot are respectively constructed as planar structures. This structure ensures a high degree of fit between the lifting guide rail and the molded material, thereby improving the stability of the lifting guide rail.

[0007] In a preferred embodiment, the first surface F of the leg profile is further provided with an L-shaped positioning shoulder, which serves as a positioning reference for the lifting guide rail. The positioning shoulder absorbs high-frequency vibrations caused by the car's start and stop, and also provides a uniform reference surface for the lifting guide rail.

[0008] In a preferred embodiment, the depth f of the positioning shoulder is set to 4 mm ± 0.1 mm. This depth matches the coefficient of thermal expansion of the aluminum profile, providing thermal expansion compensation and preventing cumulative misalignment caused by thermal stress.

[0009] In a preferred embodiment, the depth g of the concave groove is set to 3 mm ± 0.1 mm. The asymmetric depth difference between g and f disperses peak loads, reduces structural stress concentration, and prevents fatigue cracks in the molded material.

[0010] In a preferred embodiment, the leg profile is vertically connected to the face profile. Let the height of the leg profile be *c*, and the width of the face profile be *b*, where *b* > 2*c*. This structural design ensures the bending resistance of the formwork material, integrating the car bending moment borne by the F-side and the counterweight tension borne by the G-side into a self-balancing force system, thereby reducing the deformation amplitude of the formwork material.

[0011] In a preferred embodiment, the leg profile and the face profile are each provided with threaded holes for connection to external fixing equipment. The leg profile has at least one threaded hole along its height direction, and the face profile has multiple threaded holes along its width direction. The outer contours of all the threaded holes form a triangle. This triangular distribution structure not only improves locking stability but also allows the stress on the F and G surfaces to be balanced and transferred within the cross-section.

[0012] In a preferred embodiment, the face profile is further provided with at least two pin positioning holes, which are located between the threaded holes. The pin positioning holes ensure the splicing accuracy of each profile.

[0013] In a preferred embodiment, the leg profile and the face profile are each provided with multiple sets of cutouts, and the cutouts are all constructed with transition rounded corners. This structure can prevent stress concentration and make the overall equipment more reliable.

[0014] A second aspect of the present invention provides a lift for vertically transporting glass panel cassettes, comprising a profile frame assembly, a drive module, a car module, and a counterweight module. The profile frame assembly includes a bottom profile frame, a top profile frame, and at least one middle profile frame connected between the two, and also includes the mold-opening material described in any of the above embodiments. The mold-opening material is configured in two sets and fixedly connected to the inner side of each profile frame along the height direction. The drive module includes a servo motor connected to the bottom profile frame, a reducer, and a sprocket and chain assembly connected to the output end of the reducer. The car module includes a car body and a lifting guide rail slidably connected thereto. The car body is connected to the sprocket and chain assembly. The number of lifting guide rails corresponds to the number of mold-opening materials and is respectively connected to the leg profiles. The counterweight module includes a counterweight box and a counterweight mounting rail slidably connected thereto. The counterweight box is connected to the sprocket and chain assembly. The number of counterweight mounting rails corresponds to the number of mold-opening materials and is respectively connected to the counterweight connecting part.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The vertical glass panel cassette lift provided by this invention improves the structure of the open-form material that directly cooperates with the car module and the counterweight module. This ensures a high degree of fit and reference accuracy between the car lifting guide rail and the open-form material. At the same time, with high-precision counterweight module position control, the movement trajectories of the car body and the counterweight box are highly parallel, thereby effectively improving the smoothness of car operation and reducing vibration. On the other hand, through the specific orientation and specification design of the leg profiles and face profiles in the open-form material, the bending resistance of the open-form material can also be ensured, significantly reducing its deformation and further guaranteeing the smoothness of car lifting.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1

[0039] This embodiment discloses an open mold material 11 for an elevator. The open mold material 11 is assembled into a support structure for the elevator car and the counterweight box 41. The following will describe its application in conjunction with... Figures 3-9 The structure of the mold material 11 is described in detail.

[0040] See Figure 3 and combined Figure 8 The molded profile 11 has a predetermined length and is made of aluminum profile. It includes a face profile 111 and a leg profile 112 fixedly connected to one end face of the face profile 111. The face profile 111 has a first surface and a second surface. The leg profile 112 is integrally connected to the first surface of the face profile 111 along the length direction of the face profile 111. The cross-sections of the two are approximately T-shaped.

[0041] Leg profile 112 is used to connect the lifting guide rail 32 of the elevator and the car, and face profile 111 is used to connect the counterweight mounting rail and the counterweight box 41, and to connect external installation equipment.

[0042] See Figure 8 The leg profile 112 also has a first surface and a second surface. The lifting guide rail 32 is connected to its first surface. Specifically, the first surface has slots 1121 distributed along the length direction of the leg profile 112. The slots 1121 are used to insert a mounting plate that is connected to the lifting guide rail 32. The mounting plate has several mounting holes along its length for connecting with the lifting guide rail 32. By connecting the lifting guide rail 32 to the mounting plate, the lifting guide rail 32 can be fixed to the leg profile 112.

[0043] For example, the slot 1121 can be constructed as a rectangle or a C-shape. It should be noted that the corresponding positions of the inner mounting surface E and the outer surface, i.e. the first surface F of the leg profile 112, of the slot 1121 are respectively constructed as planar structures. The side of the mounting plate facing the lifting guide rail 32 is attached to the mounting surface E, and the side of the lifting guide rail 32 facing the mounting plate is attached to the first surface F of the leg profile 112, thereby enabling the lifting guide rail 32 to fit tightly to the leg profile 112. At the same time, the high degree of fit between the mounting plate and the mounting surface E can further ensure the stability of the lifting guide rail 32.

[0044] See you again Figure 8 The first surface F of the leg profile 112 is also provided with an L-shaped positioning shoulder 1123. The positioning shoulder 1123 is configured as the positioning reference of the lifting guide rail 32. The positioning shoulder 1123 can absorb the high-frequency vibration caused by the start and stop of the car, and also provide a unified reference surface for the lifting guide rail 32. Especially when multiple lifting guide rails 32 are spliced, they are all positioned against the positioning shoulder 1123 to ensure that there is no misalignment when the lifting guide rails 32 are spliced, thereby reducing vibration and improving the accuracy of the guide rail.

[0045] Preferably, the depth f of the positioning shoulder 1123 is set to 4mm ± 0.1mm. This depth can match the thermal expansion coefficient of the aluminum profile to provide thermal expansion compensation, allowing the positioning shoulder 1123 to produce a small displacement during thermal expansion and contraction without affecting the positioning accuracy and preventing cumulative misalignment caused by thermal stress.

[0046] Furthermore, the first surface G of the face profile 111 is also constructed with a counterweight connection portion 1111 for connecting the counterweight mounting rail. This counterweight connection portion 1111 corresponds to the second surface side of the leg profile 112. Specifically, the counterweight connection portion 1111 is constructed as a concave groove provided along the length direction of the face profile 111, and the depth g of the concave groove is set to 3mm ± 0.1mm. In this embodiment, the depth g of the concave groove and the depth f of the positioning shoulder 1123 have an asymmetrical depth difference, which can disperse the load peak. Specifically, when the car stops suddenly and generates an impact load, the positioning shoulder 1123 can absorb energy, while the counterweight connection portion 1111 provides rapid recovery to reduce structural stress concentration and prevent fatigue cracks from forming in the open mold profile 11.

[0047] The second side and both sides of the face profile 111 are also provided with slots 1112 for connecting external fixing equipment.

[0048] In this embodiment, the lifting guide rail 32 for connecting the car and the counterweight mounting rail for connecting the counterweight box 41 are both connected to the same open mold material 11. The first surface F of its leg profile 112 ensures the reference accuracy of the lifting guide rail 32, and the first surface G of its face profile 111 controls the position accuracy of the counterweight. The car and the counterweight box 41 connected by the rigid chain 26 form a high-precision closed-loop correction structure, so that the movement trajectories of the two are highly parallel, thereby effectively improving the stability of the car operation and reducing shaking and vibration.

[0049] Further, see Figure 8 and Figure 9 Based on the design scheme where both the lifting guide rail 32 and the counterweight mounting rail are connected to the same open formwork 11, the open formwork 11 needs to bear the weight applied by the counterweight box 41 and the car. Furthermore, the distance h1 between the car's center of gravity and the leg profile 112 of the open formwork 11 is much greater than the distance h2 between the counterweight box 41 and the leg profile 112 of the open formwork 11. Therefore, the open formwork 11 bears a large bending moment. To ensure the smoothness of the car's lifting, in this embodiment, the leg profile 112 is vertically connected to the face profile 111. When the eccentric load of the car generates a bending moment, the bending resistance characteristics of the vertical T-section simultaneously limit the deformation of the first surface F of the leg profile 112 and the first surface G of the face profile 111. (See cross-section) Figure 8 Let the height of the leg profile 112 be c, and the width of the face profile 111 be b. b and c satisfy: b > 2c. This setting can ensure the bending resistance of the open mold profile 11, so that the bending moment of the car bearing the F surface and the counterweight tension bearing the G surface are integrated into a self-balancing force system. Specifically, when the eccentric load of the car generates an overturning moment, the counterweight box 41 applies a reverse moment through the G surface track. The high bending stiffness of the T-section (b > 2c) makes the two moments cancel each other out inside the open mold profile 11, greatly reducing the deformation amplitude.

[0050] See Figure 8 The leg profile 112 and the face profile 111 are also provided with threaded holes 113, which are used for locking and connecting with the bottom fixing plate 15 and the top fixing plate 16 of the fixing equipment. The leg profile 112 has at least one threaded hole 113 along its height direction, and the face profile 111 has multiple threaded holes 113 along its width direction. The outer contours of all the threaded holes 113 form a triangle. The triangular distribution structure not only improves the locking stability, but more importantly, it allows the stress on the F / G surface to be balanced and transferred within the cross section.

[0051] In practical applications, to ensure the lifting height, a multi-set assembly structure of open-form profiles 11 is often used. To ensure the assembly accuracy of each open-form profile 11, the face profile 111 is also provided with at least two pin positioning holes 114, which are located between the threaded holes 113. Figure 5 , Figure 6 As shown, adjacent molded profiles 11 are connected and fixed by profile connectors 116.

[0052] Furthermore, the molded material 11 has multiple sets of cutouts 115 on the leg profile 112 and the face profile 111. The cutout design can reduce the weight of the molded material 11 on the one hand, and on the other hand, each cutout 115 is constructed with a transition rounded corner to prevent stress concentration and make the overall equipment more reliable.

[0053] Example 2

[0054] Based on the mold material 11 provided in Embodiment 1 above, this embodiment provides a lift for vertically transporting glass panel cassettes.

[0055] See Figure 1 and combined Figure 10 Specifically, the elevator includes a profile frame assembly 1, which is connected to the ground of each floor by screw-type chemical anchors, and also includes a drive module 2, a car module 3 and a counterweight module 4 connected through the profile frame assembly 1.

[0056] In this embodiment, the profile frame assembly 1 is made entirely of aluminum profiles, which are lightweight yet maintain strength. Figure 2 As shown, the profile frame assembly 1 includes a bottom profile frame 12, a top profile frame 13, and at least one middle profile frame 14 connecting the two, and also includes the open-form profile 11 provided in Embodiment 1. Adjacent profile frames are connected and fixed by profile connecting plates. The bottom profile frame 12 and the top profile frame 13 are respectively locked to the ground floor and the ground floor of the first floor by screw-type chemical anchors. It can be understood that they can also be connected to the ground floor of other floors according to actual needs. The open-form profile 11 is set in two sets, which are fixedly connected to the inner side of each profile frame along the height direction. The two sets of open-form profile 11 cooperate to serve as the load-bearing body of the car module 3 and the counterweight module 4.

[0057] like Figure 3 , Figure 4 As shown, the bottom end of the openable mold 11 is fixedly connected to the bottom profile frame 12 via a bottom fixing plate 15, and its top end is fixedly connected to the top profile frame 13 via a top fixing plate 16. Its middle section is connected to the corresponding profile frame via multiple middle fixing plates. One set of openable mold 11 is connected to multiple sets of photoelectric sensors 18 along its height direction to detect and locate the position of the car module 3, facilitating precise input and output of the glass panel cartridge.

[0058] In this embodiment, the leg profiles 112 of the two sets of open mold profiles 11 are arranged facing each other, and a number of reinforcing profiles 19 are connected between the two leg profiles 112 to enhance their load-bearing strength and stability.

[0059] See Figure 11 The drive module 2 is fixedly connected to the bottom profile frame 12 via the base plate 21. It includes a servo motor 22, a reducer 23, and a sprocket and chain assembly connected to the output end of the reducer 23. In the sprocket and chain assembly, the lower sprocket 24 is rotatably connected to the base plate 21, and the upper sprocket 25 is connected to the top plate 27 fixedly connected to the top profile frame 13.

[0060] See Figure 12 The car module 3 includes a car body 31 and a lifting guide rail 32 slidably connected thereto. The number of lifting guide rails 32 corresponds to the number of molded parts 11, and they are fixedly connected to the molded parts 11 respectively. The specific connection method has been described in detail in Embodiment 1, and will not be repeated in this embodiment. A plurality of sliders 17 are fixedly connected to the side of the car body 31 corresponding to the lifting guide rail 32, and are slidably connected to the lifting guide rail 32 through the sliders 17.

[0061] The car body 31 includes a support frame and a cartridge conveying module 315 connected to the support frame. Specifically, the support frame includes a support upright plate 311 and support side plates 312 fixedly connected to its two ends. A reinforcing profile 313 is fixedly connected between the two support side plates 312 to ensure its support strength. A slider 17 is fixedly connected to the support upright plate 311 on the side facing the leg profile 112, and chain fixing seats 314 for fixing the chain 26 are respectively connected to the upper and lower ends of the support upright plate 311. The cartridge conveying module 315 is fixedly connected to the support side plates 312. The cartridge carrying the glass panel is moved in and out of the car through the cartridge conveying module 315. The cartridge conveying module 315 adopts a linear conveying structure in the prior art, such as a conveyor belt structure or a roller structure. To prevent the cartridge from shaking during lifting, in this embodiment, the reinforcing profile 313 is also connected to a liftable blocking block 316 and a position detection sensor that works in conjunction with it. The blocking block 316 corresponds to the conveying end of the cartridge conveying module 315. The blocking block 316 is driven by a servo electric cylinder or pneumatic cylinder fixedly connected to the reinforcing profile 313, and the position detection sensor corresponds to the conveying front end of the cartridge conveying module 315.

[0062] See Figure 13The counterweight module 4 is used to balance the load weight, reduce motor power and energy consumption, and includes a counterweight box 41 and a counterweight mounting rail slidably connected thereto. The number of counterweight mounting rails corresponds to the number of open mold materials 11, and they are respectively fixedly connected to the counterweight connecting parts 1111 in the open mold materials 11, which have a concave groove structure. The counterweight box 41 has a number of sliding blocks 43 fixedly connected to one side corresponding to the counterweight mounting rail, which are slidably engaged with it. In other embodiments, the sliding blocks 43 can be rubber-coated rollers distributed at 90°, which cooperate with the triangular counterweight mounting rail to reduce equipment costs. The upper and lower ends of the counterweight box 41 are respectively connected to chain mounting seats 44 for fixing the chain 26, so that the counterweight box 41 moves synchronously with the car body 31.

[0063] For ease of understanding, the operating principle of the elevator for vertically transporting glass panel cassettes provided in this embodiment will be introduced by way of example, taking the glass panel cassette entering from the first floor, being lifted by the elevator to the second floor, and exiting from the second floor as an example:

[0064] The client conveys the glass panel cartridge to the cartridge conveying module 315 of the car module 3. The cartridge conveying module 315 is then activated to convey the glass panel cartridge into the car body 31. Once the arrival detection sensor detects the material's arrival, the blocking block 316 rises to prevent the cartridge from flowing back or swaying. Then, the servo motor 22 in the drive module 2 rotates, driving the chain 26 to pull the car module 3 upwards. The car body 31 moves upwards along the lifting guide rail 32. Simultaneously, the counterweight box 41 moves downwards along the counterweight mounting track. Once the photoelectric sensor 18 above detects the glass panel cartridge's arrival, the servo motor 22 stops. The glass panel cartridge reaches the second floor, the blocking block 316 descends, and the cartridge conveying module 315 moves in the opposite direction to transport the glass panel cartridge out. In drive module 2, servo motor 22 rotates, driving chain 26 to pull car module 3 downwards. Car body 31 then moves downwards along lifting guide rail 32. Simultaneously, counterweight box 41 moves upwards along counterweight mounting track. When photoelectric sensor 18 below detects that car module 3 has reached its position, servo motor 22 stops, and car module 3 returns to the first floor. This process repeats, continuously transporting glass panel cartridges from the first floor to the second floor. Similarly, the elevator can also transport glass panel cartridges in the opposite direction.

[0065] The vertical glass panel cassette lift provided by this invention improves the structure of the open mold material 11, which directly cooperates with the car module 3 and the counterweight module 4. This improves both the reference accuracy of the car lifting guide rail 32 and the position accuracy of the counterweight, ensuring a high degree of parallelism in the movement trajectories of the car body 31 and the counterweight box 41. This effectively enhances the smoothness of the car's operation and reduces vibration. Furthermore, the specific orientation and specifications of the leg profiles 112 and face profiles 111 in the open mold material 11 ensure the bending resistance of the open mold material 11, significantly reducing its deformation and further guaranteeing the smoothness of the car's lifting. This allows for low noise and low vibration during high-speed lifting under heavy loads, effectively meeting the requirements for lifting and transporting ultra-thin glass.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
