Description

Technical Field

[0001] This invention relates to the technical field of material transportation, and more particularly to a conveying system for transporting materials. Background Technology

[0002] Material conveying systems are the "blood vessels" of modern industrial production, logistics and warehousing. They generally use mechanical or pneumatic methods to achieve continuous, efficient and automated material transport from the starting point to the destination.

[0003] Based on their conveying principles and applicable scenarios, common conveying systems can be mainly divided into the following categories. 1. Belt Conveyor Working principle: A ring-shaped belt made of materials such as rubber, PVC, and polyurethane passes over two or more rollers to form a closed loop. The drive rollers drive the belt to rotate continuously through friction, thereby carrying and transporting materials.

[0004] Applications: Suitable for light to medium weight cartons, bags, pallets, and various bulk items. It has a wide range of uses and can be configured horizontally, inclined, or even turned, making it most commonly used in packaging, light industry, and logistics sorting.

[0005] 2. Roller Conveyor Working principle: It relies on a series of parallel rollers to transport materials. There are two types: gravity-driven and power-driven. Gravity-driven rollers rely on the weight of the materials or human power to push them; power-driven rollers are actively driven to rotate by chains, gears or motors.

[0006] Applications: Specifically designed for conveying rigid goods with flat bottoms, such as various boxes and pallets. Commonly used in airport baggage handling, express logistics sorting lines, and connections between production lines.

[0007] 3. Chain Conveyor Working principle: Heavy-duty chains are used instead of belts as traction and load-bearing components, usually in conjunction with steel plates or towing devices.

[0008] Applicable scenarios: It belongs to heavy-duty conveying equipment and is very suitable for working conditions with high temperature, heavy load, strong impact load or harsh environment (such as metal processing workshops, automobile manufacturing plants). It is often used to convey palletized items or large workpieces.

[0009] 4. Screw Conveyor Working principle: A rotating shaft with helical blades is installed in a closed pipe or U-shaped trough. The blades are driven to rotate by a motor, which pushes the material forward.

[0010] Application scenarios: Primarily used for conveying bulk solid or fluid materials such as grains, powders, and sludge. Due to its fully enclosed structure, it is ideal for use in controlled environments requiring dustproof, moisture-proof, or material contamination prevention.

[0011] 5. Modular Plastic Conveyor Working principle: The conveyor belt is made up of interlocking plastic modules that are spliced ​​together to form a wear-resistant and durable conveyor belt.

[0012] Applications: It possesses excellent resistance to chemical corrosion and moisture, and is easy to clean. It is widely used in food processing, beverage bottling, and cleaning processes where hygiene requirements are extremely high.

[0013] 6. Overhead Conveyor Working principle: The track is installed on the ceiling or high up, and the hoisting device, pallet or trolley is suspended and moved by chains or cables.

[0014] Applicable scenarios: It can greatly free up valuable ground space. It is widely used in garment factories for clothing transportation, automobile assembly lines for parts transfer, and post-processing operations such as painting, drying and curing.

[0015] The existing logistics conveying systems described above have relatively complex structures. This invention utilizes a simple mechanical structure combination to achieve automatic material transport and automatic operation of material trays. Summary of the Invention

[0016] This invention addresses the technical problems existing in the prior art by designing a material conveying system, including an upper conveyor chain, a lower conveyor chain, a stacking mechanism, a pushing mechanism, a tilting mechanism, and a lifting mechanism. The lifting mechanism lifts the material tray from one side of the lower conveyor chain to the same side of the upper conveyor chain. The stacking mechanism is located on the other side of the upper and lower conveyor chains. The tilting mechanism moves the material tray from the upper conveyor chain to the stacking mechanism, and then the pushing mechanism moves the material tray on the stacking mechanism to the lower conveyor chain via the tilting mechanism. The tilting mechanism includes a tilting plate, a cylinder, and a multi-link assembly. The first end of the multi-link assembly is movably connected to one side of the bottom of the tilting plate, and the output end of the cylinder is movably connected to the second end of the multi-link assembly. Driven by the cylinder, the multi-link assembly drives the tilting plate to rotate around one side of the tilting plate.

[0017] Furthermore, the pushing mechanism includes a first motor, a rotatable connecting rod, a transmission arm, a push block, and a horizontally arranged first guide rail. The connecting rod is connected to the rotating output end of the first motor. A protrusion is provided at the end of the connecting rod away from the first motor. A groove is provided along the length direction of the transmission arm, and the protrusion is located in the groove. The top of the transmission arm is connected to the push block, which can slide along the first guide rail. When the first motor is driven, the first motor drives the connecting rod to rotate. The protrusion of the connecting rod pushes the transmission arm to swing through the groove of the transmission arm. The transmission arm drives the push block to move horizontally along the first guide rail. The top of the push block pushes the material tray and pushes the material tray onto the flip plate.

[0018] Furthermore, the stacking mechanism includes four vertical supports, each with a lockable omnidirectional caster at its bottom, and a horizontal plate placed between the four vertical supports. The material trays are stacked on the horizontal plate, which has an opening slot. The top of the pusher pushes the material trays placed on the horizontal plate along the opening slot.

[0019] Furthermore, the lifting mechanism includes a base, a handle, a push rod, a sliding component, a guide component, a spring, and a fixing component. The base is provided with a guide component and a fixing component. One end of the push rod is connected to the sliding component. The push rod passes through a guide hole opened in the guide component. A spring is fitted in the middle of the push rod and is located between the guide component and the sliding component. One end of the handle is provided with a locking component, which is V-shaped. The connecting end of the V-shape is connected to one end of the handle, and one forked end of the V-shape is rotatably connected to the fixing component. When the other end of the handle is rotated, the other forked end of the V-shape will gradually enter the sliding groove opened in the sliding component, pushing the sliding component to slide, thereby pushing the push rod to move along the guide hole opened in the guide component. The other end of the push rod is connected to a tray.

[0020] Furthermore, the multi-link assembly includes a first link, a second link, a third link, and a connecting seat. One end of the first link is movably connected to the output end of the cylinder, the other end of the first link is movably connected to one end of the second link, the other end of the second link is movably connected to the connecting seat, one end of the third link is movably connected to the connecting seat, and the other end of the third link is movably connected to the bottom of the flap.

[0021] Furthermore, it also includes a pneumatic stopper, which is located on the lower conveyor chain.

[0022] Furthermore, a second motor is installed on the upper conveyor chain to drive the upper conveyor chain to operate.

[0023] Furthermore, a third motor is installed on the lower conveyor chain to drive the lower conveyor chain to operate.

[0024] Furthermore, the flap is formed by overlapping two flaps with gaps between them.

[0025] Furthermore, the pneumatic stopper includes a second cylinder and a stop component. The stop component is installed at the output end of the second cylinder and drives the second cylinder. The output end of the second cylinder pops up the stop component, preventing the material tray from continuing to run.

[0026] The main advantage of this invention is that the automatic flow of the material tray is achieved through the automatic coordinated operation of the upper and lower conveyor chains, lifting mechanism, tilting mechanism and pneumatic stop. Attached Figure Description

[0045] The main working principle of this invention is as follows: Small parts are placed into the material holes of the material tray, and then placed on a pallet on one side of the upper conveyor chain. After being placed on the upper conveyor chain, the parts are conveyed horizontally from right to left. When they reach the other side of the upper conveyor chain, the flipping mechanism starts to operate, placing the upper flipping plate diagonally downwards. The material tray slides into the stacking mechanism, and the parts in the material tray are manually removed. The flipping mechanism operates again, placing the lower flipping plate diagonally downwards. The pushing mechanism pushes the empty material tray out of the material tray via a pushing block. The empty material tray then slides diagonally downwards along the lower flipping plate into the lower conveyor chain. The lower conveyor chain runs horizontally from left to right. When it reaches the point where the lower conveyor chain is close to the pneumatic stop, the pneumatic stop operates, raising the stop block to prevent the empty material tray from continuing to move. At this time, the lifting mechanism moves downwards, moving the pallet down to the horizontal side of the lower conveyor chain. The pneumatic stop retracts the stop block. The empty material tray continues to run along the lower conveyor chain. When the material tray is placed on the pallet, the lifting mechanism starts to move upward, lifting the pallet to the side where the upper conveyor chain is horizontal. The worker then puts the parts into the material hole of the material tray and repeats the above process.
