Description

Technical Field

[0001] The present application relates to the field of transportation tools, and in particular to an automated transportation line for mechanical parts used in the production of sanitation vehicles. Background Art

[0002] At present, mechanical parts are stored in high-rise warehouses and are generally transported by climbing AGV carts or by rail vehicles carrying lifting silos.

[0003] The mechanical parts are placed directly on the silo, and the silo drives the mechanical parts to move in a lifting and translational manner to realize the transportation of the mechanical parts.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: The mechanical parts are placed directly on the silo. In some cases, the shape of the mechanical parts is uneven, which may easily cause the mechanical parts to shake when moving with the silo, thereby easily causing the mechanical parts to collide and affect the quality of transportation of the mechanical parts. Summary of the invention

[0005] In order to improve the situation that mechanical parts are easily bumped against each other and the problem that the quality of transportation of mechanical parts is affected, the present application provides an automated transportation line for mechanical parts for the production of sanitation vehicles.

[0006] The present application provides an automated transportation line for mechanical parts used in the production of sanitation vehicles, which adopts the following technical solutions: An automated transportation line for mechanical parts used in the production of sanitation vehicles, comprising: a mobile frame for moving between a three-dimensional warehouse for parts and a transportation terminal; a lifting frame, which is arranged on the mobile frame and can be lifted and moved; a loading bin is formed on the lifting frame; an elastic member, which forms an elastic chamber with a variable space size and a plurality of through ports connected to the elastic chamber; the elastic chamber is a sealed chamber; a support member, which is arranged in the elastic chamber; the support member is used to form a bearing portion and an annular support portion protruding upward relative to the bearing portion; a driving member, which is used to inject or extract air from the elastic chamber to expand or contract the elastic member; wherein the bearing portion is used to place mechanical parts; when the mechanical parts are placed on the bearing portion, the elastic member forms a positioning area that at least wraps a portion of the mechanical parts; the through port is connected to the positioning area.

[0007] By adopting the above-mentioned technical solution, the conveying of mechanical parts is realized by using a mobile frame and a lifting frame to move between the mechanical parts three-dimensional warehouse and the conveying terminal. The purpose of the elastic member and the supporting member is to place the mechanical parts to be conveyed on the bearing part, and then the annular supporting part protrudes outward relative to the bearing part, so that the mechanical parts are accommodated on the bearing part, and the mechanical parts are prevented from falling outward during the conveying process. In addition, by utilizing the expansion of the elastic member, the elastic member is pressed against the mechanical parts, and the positioning area formed can completely wrap the mechanical parts, so that the position of the mechanical parts is fixed on the bearing part, thereby preventing the mechanical parts from shaking during the transportation process, thereby preventing the mechanical parts from bumping due to shaking during the transportation process, and at the same time, the setting of the elastic member can further prevent the mechanical parts from bumping against the frame with higher hardness during the transportation process, and better ensure the safety and stability of the mechanical parts transportation process.

[0008] By adopting the above technical solution, when the elastic member wraps the mechanical member to position the mechanical member, the air in the elastic chamber will be discharged outward along the through hole, and the through hole is connected to the positioning area, so that the air will be blown directly onto the mechanical member, playing the role of blowing off the dust on the mechanical member. Among them, the driving member will continuously inject air, so when the through hole discharges air outward, it is only necessary to ensure that the air injection speed is greater than the discharge speed to ensure that the elastic chamber is in an expanded state.

[0009] Optionally, the elastic member further forms a pressure relief hole communicated with the elastic chamber; a pressure valve is arranged at the pressure relief hole.

[0010] By adopting the above-mentioned technical solution, the pressure relief hole and the pressure valve are provided to maintain the pressure in the elastic chamber. When the pressure in the elastic chamber is too high, air will be discharged outward at the pressure relief hole to prevent the elastic chamber from expanding too much and causing extrusion damage to the mechanical parts.

[0011] Optionally, a plurality of abutment members are provided on the through opening, the abutment members forming an abutment portion contacting the mechanical component and a connecting portion connecting the abutment portion with the elastic component; the connecting portion separates the abutment portion from the elastic component so that the abutment portion forms an exhaust area at the through opening; when the mechanical component is placed on the bearing portion, the driving member continuously injects air into the elastic chamber so that the elastic component expands until the abutment portion abuts against the mechanical component; the air in the elastic chamber is discharged outwardly to the mechanical component at the through opening and the exhaust area.

[0012] By adopting the above technical solution, the contact part on the elastic part is used to contact the mechanical part, thereby effectively avoiding the elastic part from directly contacting the mechanical part in a large range, thereby reducing the friction loss of the elastic part caused by the direct and large-scale contact between the elastic part and the mechanical part. An exhaust area is formed between the abutment part and the through-port, so that the air in the elastic part can be better discharged to the outside, and the mechanical part is prevented from contacting the elastic part, resulting in the through-port being blocked by the mechanical part, so that the air is better discharged to the mechanical part, and the dust of the mechanical part is cleaned.

[0013] Optionally, the abutment member includes: a first connecting plate, a second connecting plate, and a connecting tube arranged between the first connecting plate and the second connecting plate; the first connecting plate is fixed to the elastic member, and the second connecting plate is used to form the abutment portion; a plurality of filter holes are formed on the side wall of the connecting tube, a pair of filter plates are arranged in the connecting tube, and the connecting tube forms a accommodating chamber for accommodating a desiccant between the pair of filter plates; the accommodating chamber and the filter holes form the exhaust area.

[0014] By adopting the above-mentioned technical solution and utilizing the accommodating chamber formed in the connecting tube, the air in the elastic chamber will be dried by the desiccant in the accommodating chamber when it is discharged outwards, so that the air in the elastic chamber is discharged to the mechanical parts in a dry form, thereby achieving the function of dust removal and protection of the mechanical parts.

[0015] Optionally, the connecting pipe includes a first pipe segment, a second pipe segment and a third pipe segment which are sequentially connected and fixed; the diameter of the third pipe segment is larger than the diameter of the first pipe segment; and the third pipe segment is at least partially located outside the second connecting plate.

[0016] By adopting the above-mentioned technical solution, a plurality of filter holes are formed on the side wall of the connecting pipe so that the dried air is discharged laterally from the connecting pipe. Then, the diameter of the third pipe section is larger than the diameter of the first pipe section, and the third pipe section is at least partially located outside the second connecting plate. Thus, part of the air is blown onto the mechanical components along the axis of the connecting pipe, so that the dust on the mechanical components is directly blown away, thereby better cleaning the dust.

[0017] Optionally, an exhaust pipe and an adjustment structure are provided at the pressure relief hole; the exhaust pipe forms an air inlet connected to the pressure relief hole and a first exhaust port and a second exhaust port connected to the air inlet; a drying component is provided at the first exhaust port, and a humidifying component is provided at the second exhaust port; the adjustment structure is used to connect the first exhaust port with the air inlet, or connect the second exhaust port with the air inlet.

[0018] By adopting the above-mentioned technical scheme, since the air in the elastic chamber is continuously added by the external air and will be continuously discharged outwardly at the pressure relief hole, the first exhaust port and the second exhaust port arranged at the pressure relief hole will discharge the air in the elastic chamber outwardly, and the adjustment structure controls the first exhaust port to be connected with the air inlet, or the second exhaust port to be connected with the air inlet. Therefore, when the external air is humid, the air is discharged outwardly at the first exhaust port, and the humidity is reduced through the drying component at the first exhaust port; when the external air is dry, the air is discharged outwardly at the second exhaust port, and the humidity is increased through the humidifying component at the second exhaust port, thereby maintaining the humidity in the warehouse within an appropriate range to a certain extent.

[0019] Optionally, the driving member includes a pump body component and an air injection pipe; the pump body component is arranged on the lifting frame, and a port of the pump body component is connected to the elastic chamber; one end of the air injection pipe is connected to the pump body component, and the other end extends downward to a position close to the ground.

[0020] By adopting the above-mentioned technical solution, one end of the air injection pipe is connected to the pump body component, and the other end is extended to the ground, so that the air close to the ground is humidified or dried and then discharged outward at the position of the lifting frame. When the air is dry and moist, the air on the ground will be drier and more moist, so the air on the ground is mainly processed, which can better ensure that the humidity of the air is within an appropriate range.

[0021] Optionally, a filter element is provided in the elastic chamber, and the filter element is provided at a position where the pump body component is connected to the elastic chamber; the filter element forms a filter chamber having a filter surface, an air inlet and an air outlet; the pump body component allows external air to enter the elastic chamber after passing through the air inlet, the filter chamber and the air outlet in sequence; the filter surface is a conical surface, the air outlet is formed on the filter surface, and the air inlet is connected to the air injection pipe.

[0022] By adopting the above technical solution, the filter element filters the air entering the elastic chamber, thereby playing the role of air purification. In addition, the air blown on the mechanical parts is clean air, which can better blow off the dust on the mechanical parts. The filter surface formed by the filter element is a conical surface, so when the air flows on the filter surface, the space gradually becomes smaller, increasing the flow speed of the air, so that the air flows through the filter surface at a faster speed, so that when the filter surface is partially blocked, the faster air flow rate can reduce the impact of the blockage.

[0023] Optionally, the support member also includes a support spring and a base; the base is arranged on the lifting frame; the annular support portion is connected to the lifting frame, and the bearing portion is located in the middle of the annular support portion; a limiting portion is formed on the annular support portion, and the limiting portion is used to contact the bearing portion; the support spring is used to apply an upward elastic force to the bearing portion; the bearing portion moves up to abut against the limiting portion, and the bearing portion is flush with the annular support portion.

[0024] By adopting the above technical solution, it is relatively easier to place the mechanical component on the bearing portion by taking advantage of the fact that the bearing portion is flush with the annular support portion, and after the mechanical component is placed on the bearing portion, the bearing portion moves downward so that the mechanical component is accommodated in the bearing portion and the annular support portion.

[0025] Optionally, the air injection pipe is a hose; the filter element is fixed to the elastic element; when the elastic chamber expands, the elastic element drives the filter element to move to the axis of the filter surface horizontally or tilted upward; when the elastic chamber contracts, the elastic element is partially located outside the lifting frame, and the filter element is arranged on the part of the elastic element located outside the lifting frame; at this time, the filter element is hung to the outside of the lifting frame, and the axis of the filter surface is vertically downward; the air injection pipe is detachably connected to the air inlet, and when the filter element is hung to the outside of the lifting frame, the air inlet faces downward.

[0026] By adopting the above technical solution, when the elastic member contracts, the filter member hangs to the outside of the lifting frame, and the axis of the filter surface is vertically downward, so that the dust adhering to the filter surface is easy to fall off by itself, so as to facilitate the cleaning of the dust in the filter surface. In addition, when the elastic member contracts, the axis of the filter surface will be vertically downward, and when the elastic member expands, the axis of the filter surface will be horizontal or tilted upward, so that when cleaning the dust on the filter surface later, the container can be manually taken, and the elastic member can be contracted, and then the dust can be received by the container, which is convenient for collecting dust and preventing dust from leaking easily, thereby improving the efficiency of collecting dust and the effect of dust removal in the warehouse.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the mechanical parts move with the lifting frame, the elastic parts on the lifting frame expand and wrap the mechanical parts tightly, so that when the surface of the mechanical parts is uneven, there will be no shaking during transportation, avoiding bumps and collisions, and better improving the quality of transportation; 2. After the elastic member wraps around the mechanical member, the opening on the elastic member will discharge part of the air in the elastic member to the outside, and the opening will blow the air onto the mechanical member to clean the dust on the mechanical member and increase the cleanliness of the mechanical member.

[0030] The following is combined with Figure 1-17 This application is described in further detail.

[0031] The embodiment of the present application discloses an automated transportation line for mechanical parts used in the production of sanitation vehicles. The size of a sanitation vehicle is larger than that of a normal family car, so the mechanical parts used in the production of a sanitation vehicle are also much larger than those of a family car. The mechanical parts used in a family car are small in size and light in weight during transportation. Even if they are bumped during transportation, the damage caused by the bumps is small or even no damage due to the light weight. However, the mechanical parts used in a sanitation vehicle are heavy in weight. If they are bumped during transportation, they will cause greater damage, which may affect the production quality of the sanitation vehicle in some cases.

[0032] An automated transportation line for mechanical parts used in the production of sanitation vehicles comprises: a moving frame 1, a lifting frame 11, an elastic member 2, a supporting member 5, a bearing portion 51, an annular supporting portion 52 and a driving member 4.

[0033] The mobile frame 1 is used to move between the three-dimensional warehouse of parts and the transportation terminal, wherein the bottom surface of the three-dimensional warehouse is provided with a ground rail 12, and the top surface of the three-dimensional warehouse is provided with a ceiling rail 13. The mobile frame 1 is slidably connected with the ceiling rail 13 and the ground rail 12, so as to guide the movement of the mobile frame 1. The lower part of the mobile frame 1 is provided with a wheel body 14 and a first driving motor 15. The first driving motor 15 drives the wheel body 14 to rotate, and the wheel body 14 contacts the ground rail 12 to realize the movement of the mobile frame 1. The lifting frame 11 is arranged on the mobile frame 1 so as to be movable and retractable; a loading bin is formed on the lifting frame 11, and a lifting power structure 16 is arranged on the mobile frame 1. The lifting power structure 16 drives the lifting frame 11 to rise and fall on the mobile frame 1. The lifting power structure 16 adopts a winch or a lifting chain, which will not be elaborated in detail. The elastic member 2 forms an elastic chamber 21 with a variable space size and a plurality of through ports connected to the elastic chamber 21. The elastic member 2 adopts an elastic membrane body, and the through ports are holes on the elastic membrane. The elastic chamber 21 is a chamber that is sealed by wrapping an elastic film. The support member 5 is arranged in the elastic chamber 21, and the support member 5 is used to form a bearing portion 51 and an annular support portion 52 that protrudes upward relative to the bearing portion 51. The bearing portion 51 is a plate body, and the annular support portion 52 is a block or a rod body. The annular support portion 52 is partially located above the bearing portion 51, and plays a role in limiting the mechanical components on the bearing portion 51. The mechanical components are placed on the bearing portion 51, and then the annular support portion 52 protrudes outward relative to the bearing portion 51, so that the mechanical components are accommodated on the bearing portion 51, and the mechanical components are prevented from falling outward during transportation.

[0034] The driving member 4 is used to inject or extract air into or from the elastic chamber 21 to expand or contract the elastic member 2. In this example, the driving member 4 is a pump body, such as an air pump. Among them, the bearing portion 51 is used to place mechanical parts; when the mechanical parts are placed on the bearing portion 51, the elastic member 2 forms a positioning area that at least wraps part of the mechanical parts. Since the support member 5 is located in the elastic chamber 21, after the elastic membrane expands, the elastic membrane can wrap the mechanical parts to form a positioning area. By utilizing the expansion of the elastic member 2, the elastic member 2 is pressed against the mechanical parts, and the positioning area formed can completely wrap the mechanical parts, so that the position of the mechanical parts is fixed on the bearing portion 51, thereby preventing the mechanical parts from shaking during transportation, thereby preventing the mechanical parts from bumping due to shaking during transportation, and at the same time, the setting of the elastic member 2 can further prevent the mechanical parts from bumping against the frame with higher hardness during transportation, and better ensure the safety and stability of the mechanical parts during transportation.

[0035] The through-port is connected to the positioning area. The air in the elastic chamber 21 will be discharged outward at the through-port, and the through-port is connected to the positioning area, so that the air will be blown directly onto the mechanical parts, playing the role of blowing off the dust on the mechanical parts. The driving member 4 will continuously inject air, so when the through-port discharges air outward, it is only necessary to ensure that the air injection speed is greater than the discharge speed to ensure that the elastic chamber 21 is in an expanded state.

[0036] Specifically, the elastic member 2 further forms a pressure relief hole 22 connected to the elastic chamber 21; a pressure valve is arranged at the pressure relief hole 22. The pressure relief hole 22 is to prevent the pressure in the elastic chamber 21 from being too high, so that when the pressure in the elastic chamber 21 is too high, the air in the elastic chamber 21 is discharged to the outside through the pressure valve and the pressure relief hole 22, thereby protecting the elastic member 2.

[0037] Specifically, a plurality of abutment members 3 are provided on the through opening, and the abutment members 3 form an abutment portion 31 in contact with the mechanical component and a connection portion 32 connecting the abutment portion 31 with the elastic component 2. The connection portion 32 separates the abutment portion 31 from the elastic component 2, so that the abutment portion 31 forms an exhaust area at the through opening. When the mechanical component is placed on the bearing portion 51, the driving member 4 continuously injects air into the elastic chamber 21, so that the elastic component 2 expands until the abutment portion 31 abuts against the mechanical component. The air in the elastic chamber 21 is discharged outwardly to the mechanical component at the through opening and the exhaust area. Among them, the abutment portion 31 and the connection portion 32 are both made of rigid materials. The present application utilizes the abutment portion 31 on the elastic component 2 to contact with the mechanical component, effectively avoiding the elastic component 2 from directly contacting the mechanical component in a large range, thereby reducing the friction loss of the elastic component 2 caused by the direct and large-scale contact between the elastic component 2 and the mechanical component. An exhaust area is formed between the abutment portion 31 and the opening, so that the air in the elastic member 2 can be better discharged outward, and the mechanical components are prevented from contacting with the elastic components, which causes the opening to be blocked by the mechanical components. The air is better discharged to the mechanical components to clean the dust from the mechanical components.

[0038] In some other schemes of the abutment member 3, the abutment member 3 includes: a first connecting plate 33, a second connecting plate 34, and a connecting pipe 35 arranged between the first connecting plate 33 and the second connecting plate 34. The first connecting plate 33 is fixed to the elastic member 2, and the second connecting plate 34 is used to form the abutment portion 31. A plurality of filter holes are formed on the side wall of the connecting pipe 35, and the accommodating chamber 354 and the filter holes form an exhaust area. Since the first connecting plate 33 is fixed to the elastic member 2, the first connecting plate 33 will have a large area in contact with the elastic chamber 21, so that when the pressure in the elastic chamber 21 increases, the first connecting plate 33 can transmit a large force, so that the external force of the second connecting plate 34 abutting on the mechanical component increases, and the mechanical component is positioned more stably. In addition, a pair of filter plates are arranged in the connecting pipe 35, and the connecting pipe 35 forms a accommodating chamber 354 for accommodating a desiccant between the pair of filter plates. By utilizing the accommodating chamber 354 formed in the connecting tube 35, the air in the elastic chamber 21 will be dried by the desiccant in the accommodating chamber 354 when discharged outward, so that the air in the elastic chamber 21 is discharged to the mechanical parts in a dry form, thereby preventing the mechanical parts from being easily rusted due to moist air, thereby achieving the function of dust removal and protection for the mechanical parts.

[0039] In other schemes of the abutment member 3, the difference from the above scheme is that the connecting pipe 35 includes a first pipe section 351, a second pipe section 352 and a third pipe section 353 which are connected and fixed in sequence. The diameter of the third pipe section 353 is larger than the diameter of the first pipe section 351; the third pipe section 353 is at least partially located outside the second connecting plate 34. The first pipe section 351 is a straight pipe, the second pipe section 352 is a tapered pipe, and the second pipe section 352 is used to connect the first pipe section 351 with the third pipe section 353. The first pipe section 351 is connected to the first connecting plate 33, and the third pipe section 353 is connected to the second connecting plate 34. The third pipe section 353 is a straight pipe, and one end of the third pipe section 353 is connected to the second pipe section 352, and the port of the other end forms an annular plate, the middle part of the annular plate is the opening of the third pipe section 353, and the second connecting plate 34 is arranged in the middle part of the annular plate. A pair of filter plates are respectively arranged in the first pipe section 351 and the third pipe section 353, and filter holes are arranged on the first pipe section 351, the second pipe section 352 and the third pipe section 353. The filter holes are arranged on the annular plate, so that the diameter of the third pipe section 353 is larger than the diameter of the first pipe section 351, and the third pipe section 353 is at least partially located outside the second connecting plate 34, so that part of the air will be blown onto the mechanical parts along the axis of the connecting pipe 35 at the filter holes of the annular plate, so that the dust on the mechanical parts is directly blown, and the dust is better cleaned.

[0040] In some embodiments, an exhaust pipe 6 and an adjustment structure are provided at the pressure relief hole 22. The adjustment structure is a valve body. The exhaust pipe 6 forms an air inlet connected to the pressure relief hole 22 and a first exhaust port 61 and a second exhaust port 62 connected to the air inlet. The exhaust pipe 6 preferably adopts a three-way pipe. A drying component 63 is provided at the first exhaust port 61, and a humidifying component 64 is provided at the second exhaust port 62. Both the drying component 63 and the humidifying component 64 adopt the existing technology and are not described. The adjustment structure is used to connect the first exhaust port 61 with the air inlet, or the second exhaust port 62 with the air inlet.

[0041] Specifically, the driving member 4 includes a pump body component 41 and an air injection pipe 42. The pump body component 41 adopts an air pump. The pump body component 41 is arranged on the lifting frame 11, and the port of the pump body component 41 is connected to the elastic chamber 21; one end of the air injection pipe 42 is connected to the pump body component 41, and the other end extends downward to a position close to the ground. The pump body component 41 uses the air injection pipe 42 to inject air near the ground into the elastic chamber 21.

[0042] Among them, the regulating structure controls the first exhaust port 61 to be connected with the air inlet, or the second exhaust port 62 to be connected with the air inlet. Therefore, when the external air is humid, the air is discharged outward at the first exhaust port 61, and the humidity is reduced through the drying component 63 at the first exhaust port 61; when the external air is dry, the air is discharged outward at the second exhaust port 62, and the humidity is increased through the humidifying component 64 at the second exhaust port 62, so as to maintain the humidity in the warehouse within a suitable range to a certain extent. One end of the air injection pipe 42 is connected to the pump body component 41, and the other end extends to the ground, so that the air near the ground is humidified or dried and then discharged outward at the position of the lifting frame 11. Since the air on the ground will be drier and more humid when the air is dry and moist, the air on the ground is mainly processed, which can better ensure that the humidity of the air is within a suitable range.

[0043] In some other embodiments, a filter element 7 is provided in the elastic chamber 21, and the filter element 7 is provided at a position where the pump body component 41 is connected to the elastic chamber 21. In this embodiment, the filter element 7 adopts a shell structure, and the filter element 7 forms a filter chamber having a filter surface 71, an air inlet 72 and an air outlet 73. The pump body component 41 allows external air to enter the elastic chamber 21 after passing through the air inlet 72, the filter chamber and the air outlet 73 in sequence. The filter surface 71 is a conical surface, the air outlet 73 is formed on the filter surface 71, and the air inlet 72 is connected to the air injection pipe 42. Among them, the filter element 7 is a conical shell structure, and the filter surface 71 is used to connect the filter chamber in the filter element 7 with a position outside the filter element 7.

[0044] Specifically, the gas injection pipe 42 is a hose. The filter element 7 is fixed to the elastic element 2. When the elastic chamber 21 expands, the elastic element 2 will expand, that is, the elastic element 2 will change its state, and part of the elastic element 2 will be displaced, so that the filter element 7 can be driven to move, and the filter element 7 can be moved to a position where the axis of the filter surface 71 is horizontal or tilted upward.

[0045] Specifically, when the elastic chamber 21 contracts, the elastic member 2 contracts, so that the elastic member 2 is partially located outside the lifting frame 11. Since the gas injection pipe 42 is a hose, the gas injection pipe 42 cannot limit the position of the filter 7. The filter 7 is arranged on the portion of the elastic member 2 located outside the lifting frame 11, and is located outside the lifting frame 11 when the elastic member 2 is in a contracted state. Therefore, the elastic member 2 at this time plays the role of a rope compared to the filter 7. The filter 7 is a long strip shell structure, one end of the filter 7 in the length direction is fixed to the elastic member 2, and the rest of the filter 7 is not fixed to the elastic member 2. Therefore, the filter 7 is suspended outside the lifting frame 11, and the length direction of the filter 7 is perpendicular to the ground, wherein the axis of the filter surface 71 matches the length direction of the filter 7, so the filter 7 hangs to the outside of the lifting frame 11, and the axis of the filter surface 71 is vertically downward.

[0046] Specifically, the air injection pipe 42 is detachably connected to the air inlet 72, and when the filter element 7 is hung to the outside of the lifting frame 11, the air inlet 72 faces downward. Preferably, the detachable connection is made by flange connection or magnetic connection.

[0047] By adopting the above technical solution, when the elastic member 2 contracts, the filter member 7 hangs to the outside of the lifting frame 11, and the axis of the filter surface 71 is vertically downward, so that the dust adhering to the filter surface 71 is easy to fall off by itself, so that it is convenient to clean the dust in the filter surface 71. In addition, when the elastic member 2 contracts, the axis of the filter surface 71 will be vertically downward, and when the elastic member 2 expands, the axis of the filter surface 71 will be horizontal or tilted upward, so that when cleaning the dust on the filter surface 71 later, the container can be manually taken, and the elastic member 2 can be contracted, and then the dust can be received by the container, which is convenient for collecting dust and preventing dust from leaking easily, thereby improving the efficiency of collecting dust and the effect of dust removal in the warehouse.

[0048] Specifically, a cylindrical tube 8 is disposed outside the filter element 7, the filter element 7 is located inside the cylindrical tube 8, and the cylindrical tube 8 is in communication with the elastic chamber 21, thereby indirectly realizing the communication between the filter chamber and the elastic chamber 21. One end of the cylindrical tube 8 is fixed to the elastic member 2, so that the cylindrical tube 8 is used to fix one end of the filter element 7 to the elastic member 2, and after the elastic member 2 contracts, the filter element 7 is vertically downward.

[0049] In some other specific embodiments, a collection chamber 74 is further formed in the filter element 7, and the collection chamber 74 is connected to the filter chamber, wherein the collection chamber 74 is formed at the conical portion of the conical surface of the filter chamber. Then, when the external air enters the filter chamber, the air will contact the filter surface 71, and then pass through the filter surface 71 into the elastic chamber 21, but the flow direction of the air is inclined to act on the filter surface 71, so that part of the dust on the filter surface 71 will be separated from the filter surface 71, and then brought into the collection chamber 74 by the flow of air, thereby realizing the self-collection of dust in the air.

[0050] Specifically, a fixed plate 81 is provided on the cylindrical tube 8. A second drive motor 82, a pair of transmission gears 83, a connecting ring 84 and a dust cover 85 are provided on the fixed plate 81. Among them, the second drive motor 82 is installed on the fixed plate 81, and the second drive motor 82 drives the connecting ring 84 to rotate through a pair of transmission gears 83, and the connecting ring 84 is connected to the filter element 7, thereby driving the filter element 7 to rotate, and the dust cover 85 is fixed to the fixed plate 81, and the dust cover 85 wraps the pair of transmission gears 83 for dust prevention. A scraper 86 is provided in the filter chamber, and the scraper 86 is fitted with the filter surface 71, and the scraper 86 extends outward to the outside of the filter chamber and is fixed with the dust cover 85, so that the filter element 7 rotates and the scraper 86 is stationary. A power pump is provided on the cylindrical member, and an exhaust plate 87 is provided at the air outlet end of the power pump, and the exhaust plate 87 forms an exhaust chamber in contact with the outer wall surface of the filter element 7. The power pump is used to extract the air in the cylindrical tube 8 and discharge it outward in the exhaust chamber to achieve the recoil of the filter element 7. The scraper 86 and the exhaust plate 87 are located at the same angle relative to the cylindrical tube 8. The scraper 86 can prevent the filter surface 71 from being blocked by dust during use, and better ensure the speed of air entering the elastic chamber 21. The exhaust chamber back-blows the filter element 7, thereby automatically cleaning the filter element 7 to prevent blockage.

[0051] In some other embodiments, the drying member 63 includes a first tube body 631, a second tube body 632, and a drying ball 633 disposed between the first tube body 631 and the second tube body 632. A cavity is formed in the drying ball 633, and the cavity is connected with the first tube body 631 and the second tube body 632. A desiccant is filled in the cavity, and the first tube body 631 is connected with the first exhaust port 61, so that the air discharged from the first exhaust port 61 is dried by the desiccant.

[0052] In some other embodiments, the humidifier 64 includes: a third tube body 641, an annular cotton cloth 642 and a water storage tank 643. The annular cotton cloth 642 is arranged on the inner wall of the third tube body 641, and the annular cotton cloth 642 is partially immersed in the water storage tank 643, so that the annular cotton cloth 642 is in a wet state. The water storage tank 643 is fixed to the third tube body 641. The third tube body 641 is connected to the second exhaust port 62, and the air discharged outward from the second exhaust port 62 will contact the annular cotton cloth 642 in a wet state, thereby playing a role in humidifying the air. In some other schemes, an air humidifier is directly arranged outside the third tube body 641. When the third tube body 641 discharges air outward, the air humidifier is turned on, and the air discharged outward from the third tube body 641 is conducive to spraying the water mist sprayed outward from the humidifier farther, thereby increasing the range of humidification.

[0053] In other specific embodiments, the support member 5 further includes a support spring 53 and a base 54. The base 54 is disposed on the lifting frame 11, the annular support portion 52 is connected to the lifting frame 11 through the base 54, and the bearing portion 51 is located in the middle of the annular support portion 52. A limiting portion is formed on the annular support portion 52, and the limiting portion is used to contact the bearing portion 51; the support spring 53 is used to apply an upward elastic force to the bearing portion 51; the bearing portion 51 moves up to abut against the limiting portion, and the bearing portion 51 is flush with the annular support portion 52. Among them, the bearing portion 51 and the annular support portion 52 are both plate bodies. By utilizing the state that the bearing portion 51 is flush with the annular support portion 52, it is relatively easier to place the mechanical component on the bearing portion 51, and after the mechanical component is placed on the bearing portion 51, the bearing portion 51 moves downward again, so that the mechanical component is accommodated in the bearing portion 51 and the annular support portion 52.

[0054] The implementation principle of an automated transportation line for mechanical parts for sanitation vehicle production in the embodiment of the present application is as follows: The mobile rack 1 is used to move the cabinet between the three-dimensional warehouse and the location where the mechanical parts are needed. The lifting rack 11 rises on the three-dimensional warehouse to take away the parts, and the corresponding workers or manipulators place the mechanical parts on the elastic parts 2.

[0055] After the mechanical component is placed on the elastic component 2, the elastic component 2 is inflated, and the elastic component 2 expands and wraps the mechanical component tightly to prevent the mechanical component from shaking and bumping.

[0056] The air in the elastic member 2 will be discharged outwards through the opening and onto the mechanical components, thereby blowing off the dust on the mechanical components.

[0057] The external air passes through the filter element 7 and enters the elastic chamber 21 of the elastic element 2. The filter element 7 filters the air, thereby purifying the air in the workshop or warehouse.

[0058] When the external air passes through the filter element 7, the filter element 7 rotates, and the scraper 86 on the filter element 7 moves with the filter surface 71 of the filter element 7 to scrape off the dust adhering to the filter element 7. At this time, the filter element 7 is placed horizontally or tilted upward, which is conducive to collecting the dust filtered by the filter element 7 into the collection chamber 74. After the mechanical component is transported to the position where the mechanical component is needed, the external air no longer enters the elastic chamber 21, and the elastic member 2 shrinks, so that the filter element 7 is caused by gravity to face downward, and then the corresponding pipeline is disassembled, which is conducive to discharging the dust in the collection chamber 74 to the outside.

[0059] The air in the elastic chamber 21 will also be discharged outward at the position of the pressure relief hole 22, and will pass through the drying component 63 or the humidifying component 64 to dry or humidify the air. It can be set and adjusted according to the actual air environment in the workshop or warehouse.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
