This invention reduces material friction, protects the material, adapts to material shape, achieves precise positioning and angle adjustment, and facilitates feeding.

Description

Technical Field

[0001] This invention relates to the field of air flotation feeding technology, and more specifically, to a suspended forklift mobile vehicle for feeding and its method of use. Background Technology

[0002] In production operations, many raw materials or semi-finished products need to be transferred to the next processing stage. During this transfer process, in order to reduce contact damage to the materials, some companies have begun to adopt air flotation transport technology, which uses an air film formed by airflow to achieve non-contact or partial contact support between the materials and the equipment. However, existing air flotation transport devices have obvious defects.

[0003] Because different materials have different weights, a weak airflow can increase the force between the material and the air flotation platform, potentially damaging the material. Conversely, a strong airflow can cause excessive pressure on the material, making it difficult to control its position and resulting in airflow loss and wasted resources. Therefore, air flotation transport devices often rely on manual adjustment of the airflow. However, inappropriate timing or errors in manual adjustment can lead to a series of safety issues.

[0004] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a suspended forklift mobile vehicle for feeding and its method of use. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a suspended forklift mobile vehicle for feeding materials.

[0006] To achieve the above objectives, in a first aspect, the present invention provides the following technical solution: a suspended forklift trolley for feeding materials, comprising a mobile frame, wherein an air-floating structure is disposed on the mobile frame, the air-floating structure being used to support materials placed on the mobile frame, the air-floating structure comprising a support portion and a lateral stabilizing portion, the support portion being able to emit airflow, and supporting the material through an air film formed by the airflow and the surface of the material; the lateral stabilizing portion is disposed on both sides of the material, and the lateral stabilizing portion is able to emit airflow to balance the forces on both sides of the material;

[0007] The air flotation structure also includes an air supply device that provides airflow to the support portion and the lateral stabilizing portion.

[0008] Furthermore, the support includes an air-float platform disposed on the mobile frame. The surface of the air-float platform has multiple air-float cavities, and a first air guide channel is disposed within the air-float platform. Each air-float cavity is connected to the first air guide channel, and a support assembly is disposed within each air-float cavity. The support assembly is movably disposed within the air-float cavity, and a sealing element is disposed within the air-float cavity. When the support assembly is in contact with the sealing element, the air-float cavity is not connected to the outside. After the support assembly is separated from the sealing element, the air-float cavity is connected to the outside, and airflow flows to the outside through the air-float cavity.

[0009] Furthermore, the lateral stabilizer includes a movable plate mounted on the mobile frame, and symmetrically arranged forks on the movable plate, with a first air hole on each of the opposing sides of the two forks.

[0010] Furthermore, the air flotation platform has a groove, and a first side plate and a second side plate are inclinedly arranged in the groove, with the first side plate and the second side plate being symmetrically arranged; a second air hole communicating with a second air guide channel is provided on the first side plate, and a third air hole communicating with a third air guide channel is provided on the second side plate.

[0011] Furthermore, the support assembly includes a support ring disposed within the air flotation cavity, a guide rod slidably connected to the support ring, a ball seat connected to one end of the guide rod, a ball bearing disposed on the ball seat, the ball bearing rolling based on the ball seat, and an elastic element sleeved on the guide rod, the elastic element being disposed between the support ring and the ball seat.

[0012] Furthermore, the movable plate is movably mounted on the mobile frame and its height can be adjusted manually or by a drive device.

[0013] Furthermore, the two forks are slidably mounted on the movable plate and can be adjusted laterally by manual means or by a drive device.

[0014] Secondly, based on the aforementioned suspended forklift mobile vehicle, a method for its use is provided, including the following steps:

[0015] Start the air supply device and place the material onto the air flotation platform;

[0016] The material is pressed into the air flotation cavity by the support component it comes into contact with, and the airflow is guided from the airflow cavity, the second air hole and the third air hole to the bottom of the material to support the material;

[0017] When the adaptive adjustment function of the air supply device is activated, the support component drives the positioning component to move into the air flotation cavity. The sensing component can detect the distance between the positioning component and the air supply device, and convert the displacement signal of the positioning component into an electrical signal and send it to the air supply device. The air supply device then adjusts the air supply intensity.

[0018] The first air hole is controlled to direct the airflow to both sides of the material to stabilize the material;

[0019] The material is moved to the designated position, and the third air hole is closed to drive the material to move out of the moving frame, thereby realizing feeding.

[0020] Furthermore, before feeding the material, the angle of the material can be adjusted. The air supply device controls the opening and closing of the first air holes on part a and part b of the fork, so that the first air hole on part a of one of the forks is opened and the first air hole on part b is closed, and the first air hole on part a of the other fork is closed and the first air hole on part b is opened, so that an unbalanced airflow is given to both sides of the material, causing the material to rotate on the air flotation platform.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In this invention, the support components on the air flotation platform can provide dual support for the material through air flotation and contact, and can adapt to the shape and size of the material. When the material squeezes a support component, the support component moves into the air flotation cavity. At this time, the airflow will blow onto the surface of the material through the air flotation cavity to support the material. It can achieve autonomous adjustment for materials with different shapes. The corresponding receiving cavity of the support component that is not in contact with the material will not discharge airflow, thus improving the utilization rate of resources.

[0023] It is equipped with positioning components and sensing components. The sensing components can detect the displacement signal of the positioning components following the movement of the support components, and convert the displacement signal into an electrical signal and transmit it to the air supply component. The air supply component can automatically adjust the air supply intensity according to the electrical signal, so as to automatically adapt to materials of different weights and make targeted adjustments, reducing the damage rate of materials during transportation, while also reducing safety hazards and avoiding resource waste.

[0036] like Figures 1-4 As shown, this invention provides a suspended forklift trolley for feeding materials, including a trolley frame 1. The trolley frame 1 includes a bottom and handrails. All four corners of the bottom of the trolley frame 1 are equipped with casters with braking functions. Two of the casters are equipped with steering mechanisms, and the other two are equipped with drive mechanisms, facilitating movement and steering. An air-float structure is provided on the trolley frame 1 to support materials placed on it. The air-float structure includes a support part and a lateral stabilizing part. The support part is located at the bottom of the trolley frame 1 and can emit airflow. The airflow forms an air film on the surface of the material, supporting the material. The lateral stabilizing part is located on the handrails of the trolley frame 1, corresponding to both sides of the material. The lateral stabilizing part can emit airflow towards the material, balancing the forces on both sides of the material and thus stabilizing it.

[0037] The mobile frame 1 is equipped with an air supply device that provides clean and stable compressed airflow to the support and lateral stabilization parts. The air supply device includes an air compressor, a filter, a pressure reducing valve, an air tank, and an air pipe system, which are existing technologies and will not be described in detail here.

[0038] The support section supports the material through the airflow emitted, which can reduce the pressure between the material and the support section, thereby reducing the friction between the material and the air-floating platform 3 and protecting the material; and the lateral stabilizing section can drive the material to be stabilized on the moving frame 1 to prevent it from shaking during transportation.

[0039] The air flotation platform 3 is the core load-bearing component of the support unit. It is flat and fixed to the bottom of the mobile frame 1 with bolts to ensure the uniformity of the air film. Multiple air flotation chambers 12 are evenly distributed on the air flotation platform 3 (in a matrix distribution). Each air flotation chamber 12 is a cylindrical blind hole. The air flotation platform 3 has a first air guide channel 11 inside. This channel has a main channel plus branch channel structure. The main channel is set along the length of the air flotation platform 3. Each air flotation chamber 12 is connected to the main channel through a branch channel. The input end of the first air guide channel 11 is connected to the air storage tank of the air supply device through a branch air pipe.

[0040] Each air flotation chamber 12 has a sealing gasket embedded at its opening edge. The sealing gasket is a rubber sealing ring, which is press-fitted into the inner wall of the air flotation chamber 12 to ensure no airflow leakage. Each air flotation chamber 12 is equipped with a support assembly 4, used to seal the air flotation chamber 12 when there is no material and to release airflow when there is material. Specifically, it includes:

[0041] Support ring 14: It is a ring structure and is fixed to the middle of the inner wall of the air flotation cavity 12 by interference fit to form a guide and positioning structure;

[0042] Guide rod 18: It is a cylindrical rod that slides in the inner hole of the support ring 14 to ensure that the guide rod 18 slides smoothly along the axial direction;

[0043] Ball seat 16: It has a hemispherical groove 20 structure, which is fixed to the top of the guide rod 18. The inner diameter of the groove 20 is adapted to the ball 15.

[0044] Ball 15: It is embedded in the groove 20 of the ball seat 16 and can roll freely around the center of the groove 20;

[0045] Elastic component 17: This is a compression spring, sleeved on the outside of the guide rod 18. Its two ends abut against the upper surface of the support ring 14 and the lower surface of the ball seat 16, respectively. When no external force is applied, the spring force pushes the ball seat 16 upward, so that the ball 15 is in close contact with the sealing element 19 of the opening of the air flotation cavity 12. At this time, the air flotation cavity 12 is completely isolated from the outside world. When the material is placed on the ball 15, the weight of the material overcomes the spring force and pushes the ball seat 16 and the guide rod 18 downward. The ball 15 separates from the sealing element 19, and the air flotation cavity 12 is connected to the outside world through the gap between the ball 15 and the sealing element 19. The compressed airflow flows out through the first air guide channel 11, the air flotation cavity 12, and the gap, forming a uniform air film between the bottom surface of the material and the upper surface of the air flotation platform 3, realizing non-contact support of the material.

[0046] With the above structure, only the ball bearings 15 that are in contact with the material will push the ball seat 16 and guide rod 18 to move downward. The ball bearings 15 will separate from the seal 19, and the air flotation cavity 12 will be connected to the outside through the gap between the ball bearings 15 and the seal 19. The ball bearings 15 that are not in contact with the material will isolate the corresponding air flotation cavity 12 from the outside. Therefore, it can adapt well to the shape of the material.

[0047] Each air flotation chamber 12 is also equipped with a positioning element 21 and a sensing element 22. The sensing element 22 can detect the distance between the positioning element 21 and the sensing element 22, and convert the displacement signal of the positioning element 21 into an electrical signal and send it to the air supply device. The two work together to achieve adaptive adjustment of the air supply intensity. The positioning element 21 and the sensing element 22 can adopt a structure similar to a sliding rheostat, or the detection can be performed by a magnetic block plus a Hall displacement sensor.

[0048] Taking the positioning element 21 as a cylindrical magnetic positioning block and the sensing element 22 as a Hall displacement sensor as an example, the positioning element 21 is fixed on the guide rod 18, preferably at the bottom end of the guide rod 18. The axis of the positioning element 21 is coaxial with the guide rod 18 and can move synchronously along the axial direction of the air flotation cavity 12 with the guide rod 18.

[0049] The sensor 22 is fixed at the bottom center of the air flotation cavity 12 by a threaded connection (coaxial with the positioning element 21). The detection surface of the sensor 22 faces the positioning element 21, and the initial distance between the two is fixed. The sensor 22 is electrically connected to the controller of the air supply device (model optional PLC S7-200 SMART) through a waterproof wire to convert the displacement signal into an electrical signal and transmit it to the controller.

[0050] Adaptive adjustment working logic: When there is no material, the elastic element 17 of the support component 4 pushes the guide rod 18 upward, the distance between the positioning element 21 and the sensing element 22 remains at the initial value, the sensing element 22 outputs a reference electrical signal, and the air supply device maintains the minimum air supply pressure; when the material is placed on the ball bearing 15, the weight of the material pushes the guide rod 18 downward, the positioning element 21 moves downward accordingly, the distance between the two decreases, and after the sensing element 22 detects the change in distance, it outputs an electrical signal proportional to the displacement; after receiving the electrical signal, the controller automatically adjusts the opening of the pressure reducing valve of the air supply device, so that the outlet air pressure of the air flotation chamber 12 increases synchronously, ensuring that the thickness of the air film below the material is always stable at a certain value, avoiding air film rupture or material contact with the air flotation platform 3 due to changes in material weight. It also maintains the material at the same height, facilitating subsequent feeding.

[0051] like Figure 3 As shown, to further assist in the positioning of material entry and exit, an elongated groove 20 is provided on the air flotation platform 3. A first side plate 7 and a second side plate 9 are symmetrically arranged in the groove 20, and both the first side plate 7 and the second side plate 9 are inclined to the outside of the groove 20, forming a "trumpet mouth" shaped structure.

[0052] The first side plate 7 has a second air guide channel inside, and the input end of the second air guide channel is connected to the air storage tank of the air supply device through a branch air pipe. The inner side wall of the first side plate 7 has a second air hole 10, and all the second air holes 10 are connected to the second air guide channel. Similarly, the second side plate 9 has a third air guide channel inside, and the input end is connected to the air supply device. The inner side wall of the second side plate 9 has a third air hole 13 (with the same parameters as the second air hole 10), which is connected to the third air guide channel. The airflow is ejected from the second air hole 10 and the third air hole 13, forming an air cushion in the groove 20. When the material enters or exits, the edge of the material comes into contact with the airflow, reducing direct friction. At the same time, the guiding effect of the airflow can help the material accurately enter the support area of ​​the air flotation platform 3, and the second air hole 10 and the third air hole 13 can also provide support for the material.

[0053] When feeding is required, the material needs to be unloaded, and the air supply end connected to the third air port 13 is closed. At this time, there is still airflow in the second air port 10. Due to the tilt angle of the second air port 10, the material will be driven to move away from the moving frame 1, thus facilitating feeding. Furthermore, the ball bearings 15 are rolled within the ball seat 16, and there is rolling friction between the material and the ball bearings 15. Therefore, only a small force is needed to drive the material to move. It is not necessary to close all air supply ends, thus avoiding the problem of the material colliding with the air flotation platform 3 during the feeding process, which would require shutting off all air sources, and further protecting the material.

[0054] Lateral stabilizing components are located on both sides of the material to balance the lateral forces on the material through airflow, preventing the material from shifting during handling. The specific structure is as follows:

[0055] Movable plate 2: Its length is the same as that of the air-floating platform 3, and it is movably mounted on the mobile frame 1. Guide posts are fixed on the mobile frame 1 at positions corresponding to the movable plate 2. Guide holes adapted to the guide posts are opened at the four corners of the movable plate 2, allowing the movable plate 2 to slide up and down along the guide posts, thus achieving height adjustment to accommodate profiles of different sizes. Two height adjustment mechanisms are available:

[0056] Manual adjustment: A handwheel screw mechanism is installed on one side of the movable plate 2. The screw is rotatably connected to the bearing seat at the bottom of the movable frame 1 and threadedly engaged with the nut seat of the movable plate 2. Turning the handwheel can drive the movable plate 2 to rise and fall along the guide column.

[0057] Secondly, automatic adjustment is achieved through the lifting mechanism 8. For example, a ball screw mechanism driven by a servo motor is installed on one side of the movable plate 2. The movable plate 2 is lifted by the forward and reverse rotation of the motor to adapt to materials of different thicknesses.

[0058] Forks 5: Two forks 5 are slidably mounted on the inner side of each movable plate 2, with the horizontal section of the fork 5 facing upwards, used for limiting the material from both sides. Two parallel linear slide rails are fixed to the upper surface of the movable plate 2. The bottom of the fork 5 is slidably connected to the slide rails via a slider, enabling lateral adjustment of the fork 5. The lateral adjustment mechanism can also be configured in two ways:

[0059] Manual adjustment: A gear and rack mechanism driven by a handwheel is installed on the movable plate 2. Turning the handwheel drives the gear to rotate, which in turn drives the fork 5 to slide along the slide rail.

[0060] Automatic adjustment: A gear and rack mechanism driven by a stepper motor is installed on the movable plate 2. The fork 5 is driven by the motor to slide, so as to achieve automatic centering.

[0061] First air hole 6: Each of the two gripping forks 5 has a first air hole 6 on its opposite side. Each first air hole 6 is a conical hole, and the axis of the air hole is perpendicular to the side of the material. An air passage is opened inside the gripping fork 5 to communicate with the first air hole 6. The air passage is connected to the air storage tank of the air supply device through a branch air pipe. The airflow is ejected from the first air hole 6 through the air passage, forming a uniform air pressure on both sides of the material, so that the material is always kept in the center position of the device and avoids lateral displacement.

[0062] like Figure 5 As shown, the first air hole 6 on the inner side of each clamping fork 5 is divided into part a and part b along the length direction, and part a and part b are respectively connected to the air supply device through independent air passages, as detailed below:

[0063] Division method: The center line of the vertical segment of the fork 5 is used as the boundary. The first air hole 6 in the right half of the region is part a, and the first air hole 6 in the left half of the region is part b. The air hole parameters of part a and part b are completely the same, only the air path connection is independent.

[0064] Air circuit control structure: Each clamping fork 5 has an independent air passage a and an air passage b inside. The air passage a is connected only to the air hole a, and the air passage b is connected only to the air hole b. The air passage a of the two clamping forks 5 is connected to the air storage tank of the air supply device through an independent branch air pipe (PU pipe, inner diameter 6mm), and the air passage b is connected through another independent branch air pipe. Each branch air pipe is connected in series with an electromagnetic control valve. The electromagnetic control valve is electrically connected to the controller of the air supply device through a wire to realize the individual on / off control of the air holes a and b.

[0065] Material Angle Adjustment Working Logic: When the material angle needs to be adjusted, the controller controls the corresponding electromagnetic control valve to operate according to preset instructions. For example, if the material needs to rotate clockwise, the controller opens the electromagnetic control valve at part a of the left gripping fork 5 and closes the valve at part b (airflow is ejected from the upper half of the left gripping fork 5, applying an upward lateral thrust to the left side of the material), while simultaneously closing the electromagnetic control valve at part a of the right gripping fork 5 and opening the valve at part b (airflow is ejected from the lower half of the right gripping fork 5, applying a downward lateral thrust to the right side of the material). The airflow on both sides forms a clockwise torque, causing the material to rotate around the air-floating platform 3 on the air film. The rotation angle can be adjusted by controlling the airflow opening time. Similarly, if counterclockwise rotation is required, the switches at parts a and b of the two gripping forks 5 are controlled in the opposite direction. This achieves precise fine-tuning of the material angle, avoiding transport offset caused by the initial tilt of the material. Flexible adjustments can be made as needed during feeding.

[0066] Furthermore, since the ball bearing 15 and the material are subject to rolling friction, the friction generated when the material rotates can be further reduced, thus making it easier to rotate the material.

[0067] After the material reaches the target position, the controller sends a signal to the electromagnetic control valve connected in series with the third air channel to close the air supply of the third air hole 13. At this time, the second air hole 10 still supplies air, and the airflow is ejected along the inclined direction of the first side plate 7, applying an outward thrust to the bottom edge of the material. At the same time, the material and the ball bearing 15 are subjected to rolling friction. Under the action of the airflow thrust, the material moves smoothly out of the frame along the surface of the air-float platform 3 until it is completely separated from the air-float platform 3, completing the feeding. Moreover, when the material is fed, the contact area with the air-float platform 3 will become smaller and smaller, and the pressure on some support components 4 will increase. Through the cooperation of the positioning component 21 and the sensing component 22, the air supply device makes adaptive adjustments to avoid the material hitting the air-float platform 3.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
