Description

Technical Field

[0001] The present invention relates to the technical field of glass panel lifting and conveying, in particular to an elevator for cutting mold materials and vertically transporting glass panel cassettes. Background Art

[0002] In the field of glass panel manufacturing and handling, elevators for transporting glass panel cassettes vertically across floors are a crucial component of automated material handling systems (AMHS). As glass panels become thinner, their brittleness and fragility become a major challenge in vertical transport across floors. Because glass panels are fragile and sensitive to vibration, the cassettes must be raised and lowered to ensure smooth transportation of the glass panels. Existing elevators typically use steel guide rails for transporting glass panel cassettes, with the elevator car rollers running on channel steel guide rails. The large gap between the rollers and the steel guide rails creates not only high noise levels but also unstable transportation, increasing the risk of glass panel breakage. Summary of the Invention

[0003] The present invention aims to provide a lift for opening mold materials and vertically transporting glass panel cassettes, aiming to provide a high stability and low vibration lifting and transportation solution matching the glass panels.

[0004] To achieve the above object, the present invention provides the following technical solutions: A first aspect of the present invention provides an open-molded profile for an elevator, comprising a face profile and a leg profile, the face profile being provided with a first face G and a second face, the first face G being configured with a counterweight connection portion for connecting to the elevator counterweight mounting rail, the counterweight connection portion being configured as a concave groove arranged along the length direction of the face profile; the leg profile being fixedly connected to the first face G of the face profile along the length direction, the leg profile also being provided with a first face F and a second face, the counterweight connection portion corresponding to the second face of the leg profile, the first face F being provided with slots distributed along the length direction, the slots being used to install the elevator guide rails.

[0005] In a preferred embodiment, the slot is used to insert a mounting plate that mates with the lifting rail, and the inner and outer mounting surfaces of the slot are respectively constructed as flat structures. This structure ensures a high degree of fit between the lifting rail and the open mold material, thereby improving the stability of the lifting rail.

[0006] 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 not only absorbs high-frequency vibrations caused by car starting and stopping, but also provides a uniform reference surface for the lifting guide rail.

[0007] In a preferred embodiment, the depth f of the positioning shoulder is set to 4 mm ± 0.1 mm. This depth can match the thermal expansion coefficient of the aluminum profile to provide thermal expansion compensation and prevent cumulative misalignment caused by thermal stress.

[0008] In a preferred embodiment, the depth g of the concave groove is set to 3 mm ± 0.1 mm. The asymmetric depth difference between the depths g and f can disperse the load peak, reduce structural stress concentration, and prevent fatigue cracks in the open-molded material.

[0009] In a preferred embodiment, the leg profile is perpendicularly connected to the face profile. Assuming the height of the leg profile is c and the width of the face profile is b, b and c satisfy the relationship: b > 2c. This structural arrangement ensures the bending resistance of the open mold profile, integrating the car bending moment on the F surface and the counterweight tension on the G surface into a self-balancing force system, thereby reducing the deformation amplitude of the open mold profile.

[0010] In a preferred embodiment, the leg and face profiles are each provided with threaded holes for connection to external fixing devices. The leg profile has at least one threaded hole along its height, while the face profile has multiple threaded holes along its width. The connecting line of the threaded holes forms a triangle. This triangular distribution not only improves locking stability but also ensures balanced stress transfer across the F and G surfaces within the cross-section.

[0011] In a preferred embodiment, the face profile is further provided with at least two pin positioning holes, which are arranged between the threaded holes. The pin positioning holes can ensure the splicing accuracy of each open mold profile.

[0012] In a preferred embodiment, the leg profile and the face profile are further provided with a plurality of groups of hollows, each of which is constructed with transition fillets. This structure can prevent stress concentration and make the device as a whole more reliable.

[0013] The second aspect of the present invention provides an elevator 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 comprising a bottom profile frame, a top profile frame and at least one middle profile frame connected therebetween, and also comprising the open mold profiles described in any of the above schemes, the open mold profiles being arranged in two groups and being fixedly connected to the inner side of each profile frame along the height direction; the drive module comprising a servo motor connected to the bottom profile frame, a reducer and a sprocket chain assembly connected to the output end of the reducer; the car module comprising a car body and lifting guide rails slidably connected thereto, the car body being connected to the sprocket chain assembly, the lifting guide rails corresponding to the number of open mold profiles and being respectively connected to the leg profiles; the counterweight module comprising a counterweight box and a counterweight mounting rail slidably connected thereto, the counterweight box being connected to the sprocket chain assembly, the counterweight mounting rails corresponding to the number of open mold profiles and being respectively connected to the counterweight connection parts.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The elevator for vertically transporting glass panel cassettes provided by the present invention improves the open-molded profile structure that directly cooperates with the car module and the counterweight module, thereby ensuring high fit and reference accuracy between the car lifting guide rail and the open-molded profile. At the same time, combined 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 the car operation and reducing vibration; on the other hand, through the specific orientation and specification design of the leg profile and the face profile in the open-molded profile, the bending resistance of the open-molded profile can also be ensured, its deformation can be greatly reduced, and the smoothness of the car lifting can be further guaranteed.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] This embodiment discloses an open-molded material 11 for an elevator. The open-molded material 11 is combined to form a carrier for an elevator car and a counterweight box 41. Figure 3-Figure 9 The structure of the pattern member 11 will be described in detail.

[0021] See also Figure 3 Combined with Figure 8 The open mold profile 11 has a predetermined length and is made of aluminum profile, including a face profile 111 and a leg profile 112 fixedly connected to one end face of the face profile 111. The face profile 111 is provided with a first face and a second face. The leg profile 112 is integrally connected to the first face of the face profile 111 along the length direction of the face profile 111, and the cross-sections of the two are roughly T-shaped.

[0022] The leg profile 112 is used to connect the lifting guide rail 32 and the car of the elevator, and the face profile 111 is used to connect the counterweight mounting rail and the counterweight box 41, and to connect external mounting equipment.

[0023] See also Figure 8 The leg profile 112 also has a first surface and a second surface, and the lifting guide rail 32 is connected to its first surface. Specifically, the first surface is provided with slots 1121 distributed along the length direction of the leg profile 112. The slots 1121 are used to insert the mounting plate that is connected to the lifting guide rail 32. The mounting plate is provided with a plurality of mounting holes along the length direction for connecting to the lifting guide rail 32. The lifting guide rail 32 can be fixed to the leg profile 112 by connecting the lifting guide rail 32 to the mounting plate.

[0024] Exemplarily, the slot hole 1121 can be constructed into a rectangle or a C shape. It should be noted that the corresponding positions of the inner mounting surface E and the outer surface of the slot hole 1121, that is, the first surface F of the leg profile 112, 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, so that the lifting guide rail 32 can be tightly attached to the leg profile 112. At the same time, the high fit between the mounting plate and the mounting surface E can further ensure the stability of the lifting guide rail 32.

[0025] See again Figure 8 The first surface F of the leg profile 112 is also provided with an L-shaped positioning shoulder 1123, which is constructed as a positioning reference for the lifting guide rail 32. The positioning shoulder 1123 can absorb high-frequency vibrations caused by the start and stop of the car on the one hand, and provide a unified reference surface for the lifting guide rail 32 on the other hand. Especially when multiple lifting guide rails 32 are spliced, they are uniformly 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 guide rail accuracy.

[0026] Preferably, the depth f of the positioning shoulder 1123 is set to 4mm±0.1mm, which can match the thermal expansion coefficient of the aluminum profile to provide thermal expansion compensation, allowing the positioning shoulder 1123 to produce slight displacement during thermal expansion and contraction without affecting the positioning accuracy, thereby preventing cumulative dislocation caused by thermal stress.

[0027] Furthermore, the first side G of the face profile 111 is also configured with a counterweight connection portion 1111 for connecting to a counterweight mounting rail. This counterweight connection portion 1111 corresponds to the second side of the leg profile 112. Specifically, the counterweight connection portion 1111 is configured as a concave groove extending along the length of the face profile 111, with a depth g of 3 mm ± 0.1 mm. In this embodiment, an asymmetric depth difference is provided between the depth g of the concave groove and the depth f of the positioning shoulder 1123, thereby dispersing load peaks. Specifically, when an emergency stop of the car generates an impact load, the positioning shoulder 1123 can absorb the energy, while the counterweight connection portion 1111 provides rapid recovery, thereby reducing structural stress concentration and preventing fatigue cracks in the open mold profile 11.

[0028] The second surface and two side surfaces of the face profile 111 are also provided with slots 1112 for connecting external fixing devices.

[0029] 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 profile 11. The reference accuracy of the car lifting guide rail 32 is ensured by the first surface F of its leg profile 112, and the counterweight position accuracy is controlled by the first surface G of the face profile 111. The car and counterweight box 41 connected by the rigid chain 26 form a high-precision closed-loop correction structure, so that the motion trajectories of the two are highly parallel, thereby effectively improving the smoothness of the car operation and reducing shaking and vibration.

[0030] Further, see Figure 8 and Figure 9 Based on the design scheme that the lifting guide rail 32 and the counterweight mounting rail are both connected to the same open mold profile 11, the open mold profile 11 needs to bear the gravity applied by the counterweight box 41 and the car, and the distance h1 between the center of gravity of the car and the leg profile 112 of the open mold profile 11 is much larger than the distance h2 between the counterweight box 41 and the leg profile 112 of the open mold profile 11. Therefore, the open mold profile 11 is subjected to a large bending moment. In order to ensure the smooth lifting of the car, 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 make the deformation of the first surface F of the leg profile 112 and the first surface G of the face profile 111 synchronously limited, see the cross section. Figure 8 , assuming that the height of the leg profile 112 is c, the width of the face profile 111 is b, b and c satisfy: b>2c, this setting can ensure the bending resistance of the open mold profile 11, so that the car bending moment borne by the F surface and the counterweight tension borne by 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 torque through the G surface track. The high bending stiffness of the T-section (b>2c) offsets the two moments inside the open mold profile 11, greatly reducing the deformation amplitude.

[0031] See also Figure 8 The leg profile 112 and the face profile 111 are each provided with a threaded hole 113 for locking with the bottom fixing plate 15 and the top fixing plate 16 of the fixture. The leg profile 112 has at least one threaded hole 113 along its height, while the face profile 111 has multiple threaded holes 113 along its width. The connecting line of the outer contours of the threaded holes 113 forms a triangle. This triangular distribution not only improves locking stability but, more importantly, ensures balanced stress transfer across the F / G surface within the cross section.

[0032] In actual application, in order to ensure the lifting height, a plurality of groups of open mold materials 11 are often used to splice the structure. In order to ensure the splicing accuracy of each open mold material 11, the face profile 111 is also provided with at least two pin positioning holes 114, which are arranged between the threaded holes 113. Figure 5 、 Figure 6 As shown, adjacent open-molded profiles 11 are connected and fixed via profile connectors 116 .

[0033] Furthermore, the open model profile 11 is provided with a plurality of groups of hollowings 115 on the leg profile 112 and the face profile 111. On the one hand, the hollowing 115 design can reduce the weight of the open model profile 11. On the other hand, each hollowing 115 is constructed with a transition fillet to prevent stress concentration, making the overall equipment more reliable.

[0034] Example 2

[0035] Based on the molded material 11 provided in the above-mentioned embodiment 1, this embodiment provides a lift for vertically transporting glass panel cassettes.

[0036] See also Figure 1 , and combined Figure 10 Specifically, the elevator includes a profile frame assembly 1, which is locked to the ground of each floor through 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.

[0037] In this embodiment, the profile frame assembly 1 is made of aluminum profile, which is light in weight and can ensure 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 connected therebetween, and also includes the open mold profile 11 provided in Example 1. Adjacent profile frames are connected and fixed by profile connecting plates, and the bottom profile frame 12 and the top profile frame 13 are respectively locked and connected to the ground of the first floor and the ground of the second floor by screw-type chemical anchor bolts. It can be understood that they can also be connected to the ground of other floors according to actual needs. The open mold profile 11 is set into two groups, which are fixedly connected to the inner side of each profile frame in the height direction. The two groups of open mold profiles 11 cooperate to serve as the carrier of the car module 3 and the counterweight module 4.

[0038] like Figure 3 、 Figure 4 As shown, the bottom end of the open mold profile 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. The middle end is connected to the corresponding profile frame via multiple middle fixing plates. Multiple groups of photoelectric sensors 18 are connected along the height direction of one set of open mold profiles 11 to detect and locate the position of the car module 3, facilitating the precise input and output of the glass panel cassette.

[0039] In this embodiment, the leg profiles 112 of the two sets of open mold profiles 11 are arranged facing each other, and a plurality of reinforcing profiles 19 are connected between the two leg profiles 112 to enhance the bearing strength and stability thereof.

[0040] See also Figure 11 The drive module 2 is fixedly connected to the bottom profile frame 12 through the base plate 21, and includes a servo motor 22 fixedly connected to the base plate 21, a reducer 23, and a sprocket chain assembly connected to the output end of the reducer 23. In the sprocket chain assembly, the lower sprocket 24 is rotatably connected to the base plate 21, and the upper sprocket 25 is connected through a top plate 27 fixedly connected to the top profile frame 13.

[0041] See also Figure 12 The car module 3 includes a car body 31 and lifting guide rails 32 slidably connected thereto. The number of lifting guide rails 32 corresponds to the number of the open mold profiles 11 and is fixedly connected to the open mold profiles 11. The specific connection method has been detailed in Example 1 and will not be repeated in this embodiment. The car body 31 is fixedly connected to a plurality of sliders 17 on the side corresponding to the lifting guide rails 32, and is slidably connected to the lifting guide rails 32 via these sliders 17.

[0042] The car body 31 includes a support frame and a cassette conveying module 315 connected to the support frame. Specifically, the support frame includes a support vertical plate 311 and support side plates 312 fixedly connected to both ends thereof. A reinforcing profile 313 is fixedly connected between the two support side plates 312 to ensure its support strength. The slider 17 is fixedly connected to the support vertical plate 311 on the side facing the leg profile 112, and the upper and lower ends of the support vertical plate 311 are also respectively connected to chain fixing seats 314 for fixing the chain 26. The cassette conveying module 315 is fixedly connected to the support side plates 312. The cassette carrying the glass panel enters and exits the car through the cassette conveying module 315. The cassette conveying module 315 adopts a linear conveying structure in the prior art, for example, a conveyor belt structure or a roller structure. To prevent the cassette from shaking during the lifting process, in this embodiment, the reinforcing profile 313 is also connected to a liftable blocking block 316 and an in-position detection sensor that cooperates with it. The blocking block 316 corresponds to the conveying end of the cassette conveying module 315. The blocking block 316 is driven by a servo electric cylinder or an air cylinder fixedly connected to the reinforcing profile 313, and the in-position detection sensor corresponds to the conveying front end of the cassette conveying module 315.

[0043] See also Figure 13The counterweight module 4 is used to balance the load weight and reduce the motor power and energy consumption. It includes a counterweight box 41 and a counterweight mounting rail slidably connected thereto, wherein the number of the counterweight mounting rails corresponds to the number of the open mold profile 11, and they are respectively fixedly connected to the counterweight connection portion 1111 of the open mold profile 11 in the form of a concave groove. The counterweight box 41 is fixedly connected to a plurality of sliding blocks 43 that slide with the counterweight mounting rail on one side corresponding to the counterweight mounting rail. 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 and the car body 31 can move synchronously.

[0044] For ease of understanding, the following describes the operating principle of the elevator for vertically transporting a glass panel cassette provided in this embodiment. For example, a glass panel cassette enters from the first floor, is lifted to the second floor by the elevator, and is then unloaded from the second floor. The client transports the glass panel cassette to the cassette conveying module 315 of the car module 3. The cassette conveying module 315 is activated to transport the glass panel cassette into the car body 31. Once the in-place detection sensor senses the material is in place, the block 316 rises to prevent the cassette from backflowing and shaking. The servo motor 22 in the drive module 2 then rotates, driving the chain 26 to pull the car module 3 upward. The car body 31 moves upward along the lifting guide rails 32, while the counterweight box 41 simultaneously moves downward along the counterweight mounting rails. Once the photoelectric sensor 18 above senses the glass panel cassette is in place, the servo motor 22 stops, the glass panel cassette reaches the second floor, the block 316 descends, and the cassette conveying module 315 reverses direction to transport the glass panel cassette out. The servo motor 22 in the drive module 2 rotates, driving the chain 26 to pull the car module 3 downward. The car body 31 then moves downward along the lifting guide rails 32. Simultaneously, the counterweight box 41 moves upward along the counterweight mounting rails. When the photoelectric sensor 18 below senses that the car module 3 is in place, the servo motor 22 stops and the car module 3 returns to the first floor. This cycle repeats, and the elevator continuously transports the glass panel cassettes from the first floor to the second floor. Similarly, the elevator can also transport the glass panel cassettes in the opposite direction.

[0045] The elevator for vertically transporting glass panel cassettes provided by the present invention improves the structure of the open mold profile 11 that directly cooperates with the car module 3 and the counterweight module 4, which can simultaneously improve the reference accuracy of the car lifting guide rail 32 and the counterweight position accuracy, so that the movement trajectories of the car body 31 and the counterweight box 41 are highly parallel, thereby effectively improving the smoothness of the car operation and reducing vibration; on the other hand, through the specific orientation and specification design of the leg profile 112 and the face profile 111 in the open mold profile 11, the bending resistance of the open mold profile 11 can also be ensured, its deformation is greatly reduced, and the smoothness of the car lifting is further guaranteed, which can meet the low noise and low vibration requirements during high-speed lifting of large loads, and effectively meet the lifting and transportation requirements of ultra-thin glass.
