Description

Technical Field

[0001] The present invention relates to the field of material conveying technology, and in particular to an unpowered gravity-driven L-shaped slideway conveying pallet mechanism suitable for right-angle turning conveying requirements in scenarios such as warehousing logistics and production lines. Background Art

[0002] During the material flow process in warehousing logistics, production lines, etc., the flowing materials need to change direction, such as to achieve right-angle steering conveying, also known as L-shaped conveying. In this L-shaped conveying scenario, belt lines and powered roller lines need to overcome core problems such as complex steering structure, poor stability, reduced power efficiency and large space occupation. The solutions often rely on high-precision mechanical design and intelligent control systems, which increase costs and maintenance difficulties.

[0003] In view of this, it is necessary to improve the existing conveying mechanism to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing technology, the present invention provides a non-powered gravity-driven L-shaped slideway conveying pallet mechanism, which abandons the traditional power roller or belt drive and relies entirely on gravity drive. By optimizing the slideway at the corner, sliding friction is converted into rolling friction (such as bull's eye bearings), and the surface material is optimized to reduce friction resistance, and a reset spring is added for resetting the pallet after turnover, thereby reducing energy consumption and equipment complexity.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a non-powered gravity-driven L-shaped slideway conveying pallet mechanism, comprising an X-direction conveying mechanism, a Y-direction conveying mechanism, a flap mechanism and a pallet assembly, wherein one end of the X-direction conveying mechanism and one end of the Y-direction conveying mechanism are respectively connected to two sides of the flap mechanism that are perpendicular to each other to form an L-shaped slideway, and the conveying directions of the X-direction conveying mechanism and the Y-direction conveying mechanism are perpendicular to each other. The pallet assembly is located above the X-direction conveying mechanism, the flap mechanism and the Y-direction conveying mechanism and can flow along the X-direction conveying mechanism, the flap mechanism and the Y-direction conveying mechanism in sequence; The flap mechanism includes a flap assembly, an angle adjustment assembly, and a reset assembly. The flap assembly includes a flap body, a flap shaft, and a flap bearing base. Several bull's-eye bearings are evenly distributed on the top surface of the flap body to reduce sliding friction on the bottom of the tray. The bottom surface of the flap body is provided with a flap shaft rigidly connected thereto. Both ends of the flap shaft are rotatably connected to the flap bearing base via bearings. The bottom of the flap bearing base is provided with at least one first fixing bracket for securing the flap bearing base. The bottom surface of the flap bearing base is provided with a limiting groove. The top of the first fixing bracket engages within the limiting groove for limiting and positioning the flap bearing base. The angle adjustment assembly is provided on both sides of the flap bearing base for adjusting the angle of the flap body about the flap shaft. The reset assembly is provided below the flap body for resetting the flap body. To prevent the tray assembly from slipping when passing through the flap assembly, tray baffles are provided on the sides of the flap body facing the X- and Y-direction conveying mechanisms.

[0006] Furthermore, the flap assembly further includes a shaft connecting plate, which is disposed between the bottom surface of the flap body and the flap shaft, and is rigidly connected to the flap body and the flap shaft, respectively. A shaft connecting plate is disposed between the flap shaft and the flap body for fixing the flap body.

[0007] Furthermore, the flap shaft is tilted and arranged below the flap body, and the flap shaft is located outside the center of gravity of the flap body. The outside here refers to the side away from the X-direction conveying mechanism and the Y-direction conveying mechanism, close to the corner. The flap shaft is eccentrically arranged, so that when the pallet assembly flows onto the flap body, the flap body can be more easily flipped around the flap shaft, so that the flap body is tilted inward, which is more conducive to guiding the pallet assembly from the X direction to the Y direction for conveying and flowing. The dynamic adjustment of the flap body here utilizes the principle of inertia and the principle of centrifugal force during turning, so that the pallet assembly does not need power and can achieve steering and flow only under gravity drive. The angle α between the axis of the flap shaft and the conveying direction of the X-direction conveying mechanism is 35°-55°.

[0008] Furthermore, the flap bearing base includes a bottom plate and side plates, each of which is provided on either side of the bottom plate and is perpendicular to the upper surface of the bottom plate. The thickness of the bottom plate gradually decreases from one end to the other, forming an angle β between the upper and lower surfaces of the bottom plate. The angle β ranges from 3° to 7°, so that when the flap body is in the reset state, the side closer to the X-direction conveying mechanism is higher than the side closer to the Y-direction conveying mechanism. In other words, when the flap body is not in the tray assembly, it tilts from the X-direction conveying mechanism to the Y-direction conveying mechanism. When the tray assembly is transported to the flap body, it can continue to rotate from the X-direction to the Y-direction under the action of gravity.

[0009] Furthermore, the angle adjustment assembly includes an in-situ limit bolt and a flip-in-place limit bolt, the in-situ limit bolt and the flip-in-place limit bolt are arranged below the flap body and are respectively located on both sides of the flap shaft, the lower end of the in-situ limit bolt is threadedly connected to the first fixed bracket, and the height of the in-situ limit bolt relative to the first fixed bracket is adjustable, the lower end of the flip-in-place limit bolt is threadedly connected to the second fixed bracket, and the height of the flip-in-place limit bolt relative to the second fixed bracket is adjustable, by adjusting the height of the in-situ limit bolt and the flip-in-place limit bolt, the angle γ of the flip body flipping around the flap shaft is adjusted to 5°-45°. The flip angle of the flap body can be adjusted by adjusting the depth of the in-situ limit bolt and the flip-in-place limit bolt threaded in, ensuring precise connection with the X-direction and Y-direction conveying mechanisms, and adapting to the gravity and size requirements of different pallet assemblies. The limit bolt is equipped with a locking nut to prevent parameter deviation caused by vibration.

[0010] Furthermore, the reset assembly is positioned near the in-situ limit bolt and includes a reset spring and a spring connecting bolt. The upper end of the reset spring is connected to the underside of the flap body, and the lower end of the reset spring is connected to the first fixed bracket via the spring connecting bolt. The reset assembly returns the flap body to its original position, with the bottom surface of the flap body resting against the upper end of the in-situ limit bolt. The reset spring connects the flap body to the first fixed bracket. After the tray assembly detaches from the flap body and transfers to the Y-direction conveying mechanism, the flap body automatically resets to its initial angle. The reset spring's stiffness coefficient matches the maximum load of the tray assembly.

[0011] Furthermore, the X-direction conveying mechanism includes an X-bottom plate, an X-bracket is provided under the X-bottom plate, two rows of parallel X-roller groups are provided above the X-bottom plate, each row of X-roller groups includes several parallel X-rollers and X-side support plates supported at both ends of the X-rollers, and an X-bar is further provided on the outer side of the X-roller group. The X-bar is fixedly connected to the X-bottom plate through an X-connecting plate, and the height of the X-bar is higher than the top of the X-roller group, thereby realizing the function of blocking and limiting the tray assembly.

[0012] Furthermore, the Y-direction conveying mechanism includes a Y bracket formed by connecting profiles, and a plurality of Y support plates for supporting and fixing are provided at the bottom of the Y bracket, and two rows of parallel Y roller groups are provided on the top of the Y bracket, and each row of Y roller groups includes a plurality of parallel Y rollers and Y side support plates supported at both ends of the Y rollers. A Y baffle is also provided on the outside of the Y roller group, and the Y baffle is fixedly connected to the Y bracket through a Y connecting plate, and the height of the Y baffle is higher than the top of the Y roller group so as to achieve the function of blocking and limiting the tray assembly. Buffer limit assemblies are also provided on both sides of the end of the flow direction of the Y bracket, and the buffer limit assembly includes two blocking cylinders, which are respectively arranged on the left and right sides of the Y bracket, and the blocking cylinders are fixedly connected to the Y bracket through cylinder support plates, and the push rods of the blocking cylinders on both sides are opposite and face the inner side of the Y bracket.

[0013] When the pallet assembly moves to its end along the Y-direction conveying mechanism, the blocking cylinder is activated and the push rod is extended to block the guide block and the clamping plate, thereby limiting the continued movement of the pallet assembly. At the same time, the buffering of the blocking cylinder can also effectively prevent the pallet from falling off due to inertial impact.

[0014] Furthermore, the tray assembly includes a lower base plate, a product fixture, a positioning block, a support column, a positioning pin, a guide block, a clamping plate, a pressure plate and a positioning sleeve, wherein the product fixture is arranged on the lower base plate, and the bottom surface of the lower base plate is a smooth plane to facilitate reducing friction during circulation. The positioning block is arranged in the middle of the upper end of the product fixture, and a support column is respectively provided on the four corners of the positioning block, that is, there are four support columns in total, and the two clamping plates are parallel to each other, respectively arranged on the left and right sides of the product fixture, and located on the outside of the support column, there are two positioning pins, respectively arranged on the inner sides of the left and right clamping plates, and there are two guide blocks, respectively arranged at the rear ends of the two clamping plates, the guide block is L-shaped to form a guide groove, and the guide groove faces the middle of the product fixture, and a pressure plate and a positioning sleeve are provided on the product clamp outside the clamping plate.

[0015] The beneficial effects of the present invention are: 1. Adaptive angle adjustment, through the coordinated action of limit bolts and return springs, adapts to the steering requirements of pallet assemblies of different sizes and weights, improving compatibility by more than 30%.

[0016] 2. Energy consumption and maintenance costs are optimized. There is no reliance on external power, and transportation is achieved by gravity drive, with zero energy consumption. The modular design of the bull's eye bearing supports rapid replacement, improving maintenance efficiency by 50%. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 1 and Figure 2 As shown, a non-powered gravity-driven L-shaped slideway conveying pallet mechanism of the present invention includes an X-direction conveying mechanism 3, a Y-direction conveying mechanism 4, a flap mechanism 2, and a pallet assembly 1. One end of the X-direction conveying mechanism 3 and one end of the Y-direction conveying mechanism 4 are respectively connected to the two sides of the flap mechanism 2 that are perpendicular to each other, forming an L-shaped slideway, and the conveying directions of the X-direction conveying mechanism 3 and the Y-direction conveying mechanism 4 are perpendicular to each other. The pallet assembly 1 is located above the X-direction conveying mechanism 3, the flap mechanism 2, and the Y-direction conveying mechanism 4, and can flow along the X-direction conveying mechanism 3, the flap mechanism 2, and the Y-direction conveying mechanism 4 in sequence, and the direction of the pallet assembly 1 is changed by the flap mechanism 2. The red arrows in the figure represent the X-direction and Y-direction, which are perpendicular to each other.

[0033] like Figure 4As shown, the X-direction conveying mechanism 3 includes an X-bottom plate 3.2, an X-bracket 3.1 is provided below the X-bottom plate 3.2, and two rows of parallel X-roller 3.3 groups are provided above the X-bottom plate 3.2. Each row of X-roller 3.3 groups includes several parallel X-rollers 3.3 and X-side support plates 3.4 supported at both ends of the X-roller 3.3. An X-bar 3.5 is further provided on the outer side of the X-roller 3.3 group. The X-bar 3.5 is fixedly connected to the X-bottom plate 3.2 through an X-connecting plate 3.6, and the height of the X-bar 3.5 is higher than the top of the X-roller 3.3 group, thereby achieving the function of blocking and limiting the tray assembly 1.

[0034] like Figure 1 As shown, the Y-direction conveying mechanism 4 includes a Y bracket 4.1 connected by profiles, and a plurality of Y support plates 4.2 for supporting and fixing are provided at the bottom of the Y bracket 4.1. Two rows of parallel Y rollers 4.3 are provided on the top of the Y bracket 4.1. Each row of Y rollers 4.3 includes a plurality of parallel Y rollers 4.3 and Y side support plates 4.4 supported at both ends of the Y rollers 4.3. The outer side of the Y roller 4.3 group is also provided with a Y stop bar 4.5, and the Y stop bar 4.5 is fixed by a Y connecting plate 4.6. It is connected to the Y bracket 4.1, and the height of the Y baffle 4.5 is higher than the top of the Y roller 4.3 group, so as to realize the blocking and limiting function of the tray assembly 1. Buffer limit assemblies are also provided on both sides of the end of the flow direction of the Y bracket 4.1. The buffer limit assembly includes two blocking cylinders 4.7, which are respectively arranged on the left and right sides of the Y bracket 4.1, and the blocking cylinders 4.7 are fixed to the Y bracket 4.1 through the cylinder support plate 4.8. The push rods of the blocking cylinders 4.7 on both sides are opposite and face the inner side of the Y bracket 4.1.

[0035] like Figure 3As shown, the tray assembly 1 includes a lower base plate 1.1, a product fixture 1.2, a positioning block 1.3, a support column 1.4, a positioning pin 1.5, a guide block 1.6, a clamping plate 1.7, a pressure plate 1.8 and a positioning sleeve 1.9, wherein the product fixture 1.2 is arranged on the lower base plate 1.1, the bottom surface of the lower base plate 1.1 is a smooth plane, which is convenient for reducing friction during circulation, the positioning block 1.3 is arranged in the middle of the upper end of the product fixture 1.2, and a support column 1.4 is respectively provided on the four corners of the positioning block 1.3, that is, there are four support columns 1.4 in total. The support column 1.4, the two splints 1.7 are parallel to each other and are respectively arranged on the left and right sides of the product fixture 1.2 and are located on the outside of the support column 1.4. The two positioning pins 1.5 are respectively arranged on the inner sides of the left and right splints 1.7. The two guide blocks 1.6 are respectively arranged at the rear ends of the two splints 1.7. The guide blocks 1.6 are L-shaped to form a guide groove, and the guide groove faces the middle of the product fixture 1.2. The product fixture 1.2 on the outside of the splint 1.7 is provided with a pressure plate 1.8 and a positioning sleeve 1.9. The tray assembly 1 in this embodiment is mainly used to realize the circulation of the BRP actuator. Therefore, each structure of the tray assembly 1 is matched with the structure of the BRP actuator to realize the fixation of the BRP actuator on the pallet. The tray assembly 1 includes but is not limited to being used for the BRP actuator, and can also be a circulation tray for other products, which will not be described here one by one.

[0036] like Figure 4-Figure 7As shown, the flap mechanism 2 includes a flap assembly, an angle adjustment assembly and a reset assembly. The flap assembly includes a flap body 2.1, a flap shaft 2.2 and a flap bearing base 2.3. A number of dust-proof and sealed bull's eye bearings 2.11 are evenly distributed on the top surface of the flap body 2.1 to reduce the sliding friction at the bottom of the tray and prevent jamming or sudden speed changes. Preferably, the bottom surface of the flap body 2.1 is provided with a flap shaft 2.2 rigidly connected to it, and the two ends of the flap shaft 2.2 are respectively rotatably connected to the flap bearing base 2.3 through bearings. The bottom of the flap bearing base 2.3 is provided with at least one first fixing bracket 2.5 for fixing the flap bearing base 2.3. In this embodiment, there are two first fixing brackets 2.5, which are arranged in parallel below the flip bearing base. A limiting groove 2.31c is provided on the bottom surface of the flap bearing base 2.3, and the top of the first fixing bracket 2.5 is embedded in the limiting groove 2.31c for limiting and positioning the flap bearing base 2.3. The angle adjustment assembly is arranged on both sides of the flap bearing base 2.3 for adjusting the flipping angle of the flap body 2.1 around the flap shaft 2.2; the reset assembly is arranged below the flap body 2.1 for resetting the position of the flap body 2.1. To prevent the tray assembly 1 from sliding when passing through the flap assembly, tray stoppers 2.12 are installed on the sides of the flap body 2.1 facing the X-direction conveyor mechanism 3 and the Y-direction conveyor mechanism 4. The flap assembly also includes a shaft connecting plate 2.4, which is positioned between the bottom surface of the flap body 2.1 and the flap shaft 2.2 and is rigidly connected to both the flap body 2.1 and the flap shaft 2.2.

[0037] like Figure 5 As shown, the flap shaft 2.2 is tilted below the flap body 2.1, and the flap shaft 2.2 is located outside the center of gravity of the flap body 2.1. The outside here refers to the side away from the X-direction conveying mechanism 3 and the Y-direction conveying mechanism 4, close to the corner. The flap shaft 2.2 is eccentrically arranged, so that when the pallet assembly 1 flows onto the flap body 2.1, the flap body 2.1 can be more easily flipped around the flap shaft 2.2, so that the flap body 2.1 is tilted inward, which is more conducive to guiding the pallet assembly 1 from the X direction to the Y direction for conveying and flowing. The dynamic adjustment of the flap body 2.1 here utilizes the principle of inertia and the principle of centrifugal force during turning, so that the pallet assembly 1 does not need power and can achieve steering and flow only under gravity drive. The angle α between the axis of the flap shaft 2.2 and the conveying direction of the X-direction conveying mechanism 3 is 35°-55°.

[0038] like Figure 8 and Figure 9As shown, the flap bearing base 2.3 includes a bottom plate 2.31 and side plates 2.32. The side plates 2.32 are disposed on either side of the bottom plate 2.31 and are perpendicular to the upper surface 2.31a of the bottom plate 2.31. The thickness of the bottom plate 2.31 gradually decreases from one end to the other, forming an angle β between the upper surface 2.31a and the lower surface 2.31b of the bottom plate 2.31. The angle β ranges from 3° to 7°. This causes the flap body 2.1, in the reset state, to be positioned closer to the X-direction conveying mechanism 3 than closer to the Y-direction conveying mechanism 4. In other words, when the tray assembly 1 is not present, the flap body 2.1 tilts from the X-direction conveying mechanism 3 toward the Y-direction conveying mechanism 4. This allows the flap body 2.1 to continue to rotate from the X-direction to the Y-direction under the action of gravity when the tray assembly 1 is transferred onto the flap body 2.1.

[0039] like Figure 7 and Figure 10 As shown, the angle adjustment assembly includes an in-situ limit bolt 2.6 and a flip-in-place limit bolt 2.7, the in-situ limit bolt 2.6 and the flip-in-place limit bolt 2.7 are arranged below the flap body 2.1, and are respectively located on both sides of the flap rotation axis 2.2, the lower end of the in-situ limit bolt 2.6 is threadedly connected to the first fixed bracket 2.5, and the height of the in-situ limit bolt 2.6 relative to the first fixed bracket 2.5 is adjustable, the lower end of the flip-in-place limit bolt 2.7 is threadedly connected to the second fixed bracket 2.8, and the height of the flip-in-place limit bolt 2.7 relative to the second fixed bracket 2.8 is adjustable, by adjusting the height of the in-situ limit bolt 2.6 and the flip-in-place limit bolt 2.7, the angle γ of the flip body 2.1 flipping around the flap rotation axis 2.2 is in the range of 5°-45°. Figure 10 The red line in the middle indicates the reset position of the flap body 2.1, and the blue line indicates the position of the flap body 2.1 when the tray assembly 1 flows onto the flap body 2.1 and gradually flows toward the Y direction conveying mechanism, that is, a schematic diagram of the flipped into place state.

[0040] like Figure 6 and Figure 7 As shown, the reset assembly is located on the side near the original position limit bolt 2.6, and includes a reset spring 2.9 and a spring connecting bolt 2.10. The upper end of the reset spring 2.9 is connected to the bottom of the flap body 2.1, and the lower end of the reset spring 2.9 is connected to the first fixed bracket 2.5 via the spring connecting bolt 2.10. The reset assembly restores the flap body 2.1 to its original position, that is, the bottom surface of the flap body 2.1 abuts against the upper end of the original position limit bolt 2.6. Due to the elasticity of the reset spring 2.9, Figure 6 and Figure 7Return spring 2.9 is not stretched, so its lower end is separated from spring connecting bolt 2.10. During assembly, the lower end of return spring 2.9 is connected to spring connecting bolt 2.10 and can be directly hung on it. The stiffness coefficient of return spring 2.9 is linked to the maximum load of tray assembly 1. After tray assembly 1 is separated from flap body 2.1, flap body 2.1 automatically returns to its initial position, eliminating manual intervention.

[0041] Working principle: 1. Pallet gravity triggers flipping As the tray assembly 1 slides along the X-direction conveyor 3 to the flap mechanism 2 area, its gravity forces the flap body 2.1 to tilt downward around the flap pivot 2.2, forming a slideway that tilts from the X-direction to the Y-direction. The angle of the flap body 2.1 is dynamically constrained by two limit screws, ensuring a smooth transition with the Y-direction conveyor 4. In this embodiment, the slideway surface material is optimized: the bull's eye bearing 2.11 is made of a highly wear-resistant material such as polytetrafluoroethylene to reduce friction and extend its service life.

[0042] 2. Low-resistance glide control The bull's eye bearing 2.11 reduces sliding friction between the contact surface of the tray assembly 1 and the flap body 2.1, preventing the tray from getting stuck or experiencing sudden speed changes. A buffer limit assembly is provided at the end of the Y-direction conveying mechanism 4 to prevent the tray from falling off due to inertial impact.

[0043] With the above-described preferred embodiments of the present invention as inspiration, and with reference to the above description, relevant personnel may make various changes and modifications without departing from the scope of the present invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
