Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a suspended conveying system for automated three-dimensional warehouses. Background Technology

[0002] As a new type of warehousing and transportation technology, automated warehouses can make more comprehensive use of space and reduce the economic, time and space costs of warehousing and transportation. Since the storage method of goods in the warehouse has changed, the transportation and transfer method must also change accordingly. The simple handling by manual labor or forklifts in traditional technology can no longer meet the automated operation requirements of automated warehouses.

[0003] Overhead conveyor systems are widely used in this type of warehouse due to their good transport efficiency, minimal space constraints, and relatively high transport capacity. For example, a cargo transfer device for an automated warehouse (AS / RS) with publication number CN204038312U includes a material hanger, multiple transfer lifts located at the ends of multiple storage roller beds perpendicular to the EMS trolley tracks, and skids matching the rollers on the storage roller beds. The upper part of the material hanger has a horizontal hanging rod corresponding to the EMS conveyor trolley, and its front and rear sides are equipped with U-shaped pin seats with downward openings corresponding to the locking pins on both sides of the skids. The transfer lifts include a fixed support, two conveyor platforms, and a conveyor platform drive device. The two conveyor platforms are connected to the fixed support via vertical slides, with a material hanger channel between them. Each conveyor platform is equipped with guide wheels corresponding to the skids. This application achieves seamless integration between the intelligent storage warehouse and the EMS conveyor system, greatly improving cargo storage and retrieval efficiency, reducing the occupation of logistics and distribution personnel, and lowering material storage and retrieval costs.

[0004] However, such overhead conveyor systems often have some limitations in actual use. For example, when using cargo frames to centrally transport and transfer goods, long-term storage can lead to a lot of dust accumulating on the surface of the goods. Existing technologies cannot fully clean the goods in the cargo frames by simply sweeping them. At the same time, using equipment such as air pumps will significantly increase the load on the overhead conveyor system, resulting in excessively high actual costs. Summary of the Invention

[0005] The purpose of this invention is to provide an overhead conveyor system for automated storage and retrieval systems, in order to solve the limitations of existing overhead conveyor systems mentioned in the background art in actual use. For example, during the centralized transportation and transfer of goods using cargo frames, long-term storage can lead to the accumulation of a lot of dust on the surface of the goods. The existing technology cannot fully clean the goods in the cargo frames by simply sweeping them. At the same time, the use of equipment such as air pumps will also greatly increase the load on the overhead conveyor system, resulting in excessively high actual costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an overhead conveyor system for an automated three-dimensional warehouse, comprising a fixing clamp for fixing a cargo frame, wherein the fixing clamp is connected to the lower part of the conveyor system body, and the top of the conveyor system body is slidably mounted in a hanging rail via an electric wheel set; a moving control plate is installed below the conveyor system body, and the moving control plate is used to install and drive the fixing clamp to horizontally clamp or release the cargo frame; a limiting cover is flexibly connected below the moving control plate, and the limiting cover covers the cargo in the cargo frame to maintain the relative stability of the cargo; and airflow holes are provided on the inner surfaces of the fixing clamps located on both sides of the conveyor system body, the airflow holes generating airflow through the movement of the conveyor system body and blowing it toward the cargo to achieve automatic cleaning.

[0007] As a further step, the top of the movable control plate is connected to the vibration mechanism via a slide rod. The vibration mechanism drives the fixed clamping plate and the cargo frame between the fixed clamping plates to move up and down through the movable control plate, generating vibration and simultaneously generating airflow that is ejected from the airflow nozzle.

[0008] As a further step, the inner wall of the fixed clamp is also provided with horizontally distributed rollers, wherein the rollers are rotatably installed in the fixed clamp via a rotating mechanism, wherein the rollers are used to clamp the cargo frame in the initial state and to move the cargo frame up and down in the vibration state, wherein the outer surface of the rollers is also provided with anti-slip strips at equal angles.

[0009] As a further step, the rotating mechanism includes a one-way bearing and a scroll spring, wherein the inner ring of the one-way bearing is fixedly connected to the end of the roller shaft, while the outer ring of the bearing is damped and rotatably mounted in a fixed clamping plate.

[0010] As a further step, the airflow nozzle is connected to an air chamber formed in a fixed clamping plate, wherein the air chamber is connected to an air supply mechanism via an air pipe, and the air supply mechanism generates airflow and delivers the airflow to the air pipe through the operation of a vibration mechanism.

[0011] As a further step, the gas supply mechanism includes a valve plate and a gas delivery clamping fixing plate, wherein the gas delivery clamping fixing plate is opened inside the main body of the conveying system, and the valve plate fixed to the bottom end of the slide rod is vertically slidably connected in the gas delivery clamping fixing plate.

[0012] As a further step, the valve plate divides the gas delivery clamping fixing plate into upper and lower sections, each of which is provided with a one-way input end and an output end. The output end of the upper section is connected to the input end of the air pipe, while the input end of the lower section is connected to the internal space of the limiting cover plate through a flexible tube. The internal hollow space of the limiting cover plate is connected to a suction hole opened on the lower end face of the limiting cover plate. The suction hole is used to suck out the dust-laden airflow blown out by the airflow blowing hole. Moreover, the output end of the lower half of the gas delivery clamping fixing plate is connected to the dust collection mechanism.

[0013] As a further step, the vibration mechanism includes a telescopic rod, which is fixedly installed on the main body of the conveying system, and its output end is connected to a slide rod.

[0014] As a further step, the vibration mechanism includes a first magnetic plate and a second magnetic plate, which are arranged opposite each other with magnetic repulsion. The first magnetic plate is mounted on the hanging rail by a bracket, while the second magnetic plate is fixed to the top of the slide rod, which is elastically slidably mounted in the main body of the conveying system.

[0015] Furthermore, both the second magnetic plate and the first magnetic plate are inclined, and multiple first magnetic plates are equally spaced. The first magnetic plates are also rotatably mounted in the bracket via pins.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the overhead conveyor system for automated storage and retrieval systems adopts a novel overhead clamping conveying method, resulting in better conveying performance. It can generate power and drive airflow by moving the overhead conveyor system without using equipment such as air pumps. Simultaneously, the airflow generating mechanism can assist in the stable movement of the overhead conveyor system, making it more energy-efficient and environmentally friendly, as detailed below:

[0017] 1. Firstly, the use of the limiting cover plate and the moving control plate enables the suspended conveyor system to use the vibration mechanism to make the moving control plate and the fixed clamping plate holding the cargo frame vibrate up and down during operation. This vibration makes the distribution of goods in the cargo frame more uniform and can achieve a certain degree of dust shaking effect. The use of the limiting cover plate can ensure the stable distribution of goods in the cargo frame.

[0018] 2. The combined use of the first magnetic plate and the second magnetic plate can utilize the intermittent repulsion effect between the two, combined with the overall movement of the suspended conveyor system and the rebound effect of the slide bar, so that the suspended conveyor system can spontaneously move up and down and vibrate during the movement, thereby replacing the use of existing equipment such as vibration motors to achieve the vibration effect.

[0019] Furthermore, the mutual tilting and relative distribution of the magnetic plates allows the suspended conveyor system to be propelled by the magnetic repulsion force during movement, thus making its movement more stable and more energy-efficient and environmentally friendly.

[0020] Furthermore, the structural design of the slide bar and valve plate below the magnetic plate allows it to generate a pneumatic conveying effect by using the movement of the slide plate and the reciprocating up and down movement of the valve plate while producing a vibration effect. This enables the limiting cover plate and the fixing clamp plate to achieve the effects of dust suction and blowing away, respectively.

[0021] Furthermore, the use of rollers can not only stably clamp the cargo frame in the initial state, but also, when the cargo frame vibrates up and down, utilize the acceleration effect generated by the vibration to allow the cargo frame to move up and down relative to the fixed clamping plate support during the overall vibration, thereby further improving the conveying and dust removal effects.

[0033] 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.

[0034] Please see Figures 1-10 The present invention provides the following technical solution:

[0035] Example 1: In this example, to solve the problems existing in the prior art, the following solution is disclosed for reference. Figures 1-4 The system includes a fixing clamp 1 for securing the cargo frame, which is connected to the lower part of the conveyor system body 2. The top of the conveyor system body 2 is slidably mounted in the overhead rail 3 via an electric wheel set. A movement control plate 4 is installed below the conveyor system body 2, which is used to install and drive the fixing clamp 1 to horizontally clamp or release the cargo frame. A limiting cover 5 is flexibly connected below the movement control plate 4. The limiting cover 5 covers the cargo in the cargo frame to maintain the relative stability of the cargo. Airflow holes 8 are opened on the inner surface of the fixing clamp 1 located on both sides of the conveyor system body 2. The airflow holes 8 generate airflow through the movement of the conveyor system body 2 and blow it onto the cargo to achieve automatic cleaning. The top of the movable control plate 4 is connected to the vibration mechanism via the slide rod 6. The vibration mechanism drives the fixed clamping plate 1 and the cargo frame between the fixed clamping plate 1 to move up and down through the movable control plate 4, generating vibration and simultaneously generating airflow that is ejected from the airflow nozzle 8. The fixed clamping plate 1 moves horizontally under the drive of existing equipment such as cylinders, thereby clamping the cargo frame. The entire conveying system moves in the overhead rail 3. During the movement, the vibration mechanism drives the movable control plate 4 and the cargo frame to move up and down in a vibrating state through the slide rod 6. In this way, the dust accumulated on the surface of the goods can be shaken off accordingly. Furthermore, this vibration treatment method can make the distribution of goods in the cargo frame more stable and uniform.

[0036] In this embodiment, another solution is disclosed, the effect of which is mainly reflected in increasing the movement dimension of the cargo frame to enhance the vibration effect. For details, please refer to... Figures 5-6 The inner wall of the fixed clamping plate 1 is also provided with horizontally distributed rollers 7, which are rotatably installed in the fixed clamping plate 1 via a rotating mechanism. The rollers 7 are used to clamp the cargo frame in the initial state and to move the cargo frame up and down in the vibration state. The outer surface of the rollers 7 is also provided with anti-slip strips 10 at equal angles. The rotating mechanism includes a one-way bearing 11 and a scroll spring. The inner ring of the one-way bearing 11 is fixedly connected to the end of the roller 7, while the outer ring of the bearing is damped and rotatably installed in the fixed clamping plate 1. In the initial state, there is a static distance between the one-way bearing 11 and the fixed clamping plate 1. The friction force, i.e. the damping coefficient, is relatively high. Therefore, when the goods are slowly moved up and down, the roller 7 will not rotate. However, during vibration, such as during high-speed upward movement, the goods in the cargo frame have a tendency to move downward with relative acceleration. Combined with the weight of the object itself, the roller 7 will deflect accordingly and drive the goods downward. When moving downward at high speed, the goods will move upward under the rebound effect of the spring on the roller 7. This allows the goods to be in a state of up and down movement in the conveyor system. Combined with the airflow blowing and vibration effects, the dust removal effect on the goods can be more thorough.

[0037] In this embodiment, a solution is provided to generate airflow instead of existing equipment such as air pumps. Referring to the accompanying drawings, the airflow nozzle 8 is connected to the air chamber 9 located in the fixed clamping plate 1. The air chamber 9 is connected to the air supply mechanism via the air pipe 14. The air supply mechanism generates airflow through the operation of a vibration mechanism and delivers the airflow to the air pipe 14. The air supply mechanism includes a valve plate 13 and a fixed clamping plate 12 for air delivery. The fixed clamping plate 12 for air delivery is located inside the main body 2 of the conveying system and is fixed to the slide rod 6. The valve plate 13 at the bottom is vertically slidably connected to the gas supply clamping fixing plate 12. The valve plate 13 divides the gas supply clamping fixing plate 12 into upper and lower sections. Both sections are provided with a one-way input end and an output end. The output end of the upper section is connected to the input end of the air pipe 14, while the input end of the lower section is connected to the internal space of the limiting cover plate 5 through the hose 16. The hollow space inside the limiting cover plate 5 is connected to the suction hole 15 opened on the lower end face of the limiting cover plate 5. The suction hole 15 is used to blow the airflow through the blowing hole 8. The dust-laden airflow is drawn out, and the output end of the lower half of the space in the fixed clamping plate 12 for air delivery is connected to the dust collection mechanism. The vibration mechanism includes a telescopic rod 17, which is fixedly installed on the main body 2 of the conveying system. Its output end is connected to the slide rod 6. The vibration mechanism drives the slide rod 6 to move up and down, so that the moving control plate 4 can drive the fixed clamping plate 1 and the cargo frame in the fixed clamping plate 1 to vibrate up and down. At the same time, the valve plate 13 fixed at the bottom of the slide rod 6 will also move synchronously in the fixed clamping plate 12 for air delivery. The fixed clamp 12 moves up and down. When the upper and lower sections of the fixed clamp 12 are compressed or stretched, they can achieve the effect of air pressure delivery and discharge. For example, when the upper section is compressed, it can blow air out from the air blow hole 8 to achieve the effect of air cleaning. When the lower section is stretched, it can generate negative pressure suction, so that the blown-away dust can be absorbed by the suction hole 15 and discharged from the output end of the space. Therefore, the goods can be handled more properly, and there is no need to use air pumps or other equipment, which is more energy-saving and environmentally friendly.

[0038] Example 2: Unlike the above examples, the vibration mechanism in this example consists of two sets of magnetic plates, upper and lower. For details, please refer to... Figures 9-10The vibration mechanism includes a first magnetic plate 18 and a second magnetic plate 20, which are arranged opposite each other with magnetic repulsion. The first magnetic plate 18 is mounted on the hanging rail 3 via a bracket 19, while the second magnetic plate 20 is fixed to the top of a slide rod 6. The slide rod 6 is elastically slidably mounted in the main body 2 of the conveying system. Both the second magnetic plate 20 and the first magnetic plate 18 are inclined, and multiple first magnetic plates 18 are evenly spaced. The first magnetic plates 18 are also rotatably mounted in the bracket 19 via pins 21. The entire main body 2 of the conveying system moves along the hanging rail 3. During operation, the position of the second magnetic plate 20 at the top of the main body 2 of the conveying system also changes in real time. When it corresponds to the lower end face of the first magnetic plate 18, the repulsive thrust generated by the two magnetic plates will drive the entire moving control plate 4 to move downward. When they are separated, the slide rod 6 will rebound and move accordingly, thereby replacing the vibration motor or hydraulic rod to generate a vibration effect. At the same time, since the magnetic plates are inclined, while generating vertical downward pressure, they can also generate thrust along the moving direction of the suspended conveying system, making its movement more stable and more energy-efficient.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
