Description

Technical Field

[0001] This invention belongs to the field of automated warehouse technology, specifically a vertical lifting container with dual retrieval on the same floor for automated warehouses. Background Technology

[0002] An automated warehouse is a warehousing system that utilizes high-rise racks, automated equipment, and computer management systems to achieve efficient storage and retrieval of goods.

[0003] Existing automated warehouse technologies using dual-level vertical lift storage units (DLLs) employ dual gripping mechanisms to simultaneously retrieve goods from two rows of racks on the same level. However, when handling cardboard boxes, the current gripping method, which uses pressure clamping from both sides, easily causes deformation and damage to the outer surface of the boxed goods during retrieval, resulting in poor safety during actual retrieval. Furthermore, the cleaning of boxed goods upon entry into the warehouse typically involves external fans. While these fans can remove surface dust, the resulting dust accumulation hinders further dust removal and leads to dust buildup inside the double-row racks, resulting in mediocre cleaning performance and overall poor usability. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical lifting container with dual retrieval on the same floor for automated warehouses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical lifting cabinet with double retrieval on the same floor for an automated warehouse, comprising a cabinet outer frame, double-row shelves embedded inside the cabinet outer frame, and a lifting mechanism disposed inside the cabinet outer frame. The double-row shelves are equipped with a storage and retrieval moving platform inside. The top of the storage and retrieval moving platform is symmetrically equipped with support components. A moving arm is elastically sleeved inside the support components. An adsorption gripping part is fixedly provided on the end face of the moving arm. A buffer moving part is provided on the outside of the adsorption gripping part. A composite control component is provided at the end of the moving arm. An exhaust and suction component is fixedly provided on the outside of the support components. An exhaust and suction treatment part is provided on the front of the support components. An air pump is provided at the bottom of the storage and retrieval moving platform. The air pump controls the extension and retraction of the moving arm through the support components.

[0006] The composite control component drives the adsorption gripping part and the buffer moving part to complete the contact adsorption and fixation of the outer side of the goods. The composite control component reciprocates to compress the suction and exhaust components and repeatedly blows and sucks in the air near the stored goods through the suction and exhaust processing part connected to the suction and exhaust components.

[0007] Preferably, the support assembly includes a support frame, a middle partition, a bottom frame, and a connecting air passage. The middle partition is fixed inside the support frame, the bottom frame is fixed to the top of the access moving platform, and the upper end of the bottom frame is fixedly connected to the support frame. The connecting air passage is opened in the bottom frame. The access moving platform has a middle air passage inside. The air pump inputs pressurized air into the support frame through the middle air passage and the connecting air passage. The top of the access moving platform is provided with a guide roller.

[0008] Preferably, the composite control component includes a motor and a cam, the motor is fixed on the moving arm, the cam is fixed on the output shaft of the motor, and the adsorption gripping part and the suction and exhaust assembly are located on both sides of the cam.

[0009] Preferably, the adsorption gripping part includes an assembly frame, a movable frame, a suction pump, and a suction hole. The movable frame is movably mounted in the assembly frame. The suction pump is fixed to the top of the movable frame and draws gas from inside the movable frame. The suction hole is opened on the front of the movable frame and communicates with the movable frame.

[0010] Preferably, the buffer moving part includes an elastic layer, a spring, and a guide arc surface. The elastic layer is fixed on the front of the movable frame, and a connecting hole is provided on the elastic layer. The connecting hole is connected to the air intake hole one by one. One end of the spring is fixed to the side of the movable frame through a connecting block, and the other end of the spring is fixedly connected to the assembly frame, so that the movable frame is elastically fitted into the assembly frame. The guide arc surface is opened at one corner of the side of the movable frame, and the position of the guide arc surface is adapted to the position of the cam.

[0011] Preferably, the intake and exhaust assembly includes an elastic airbag, a connecting plate, a connecting rod, and an arc-shaped guide plate. The connecting rod is fixed between the connecting plate and the arc-shaped guide plate. The connecting plate is fixed on the elastic airbag. The position of the arc-shaped guide plate is adapted to the cam. When the cam approaches the arc-shaped guide plate and rotates, the cam reciprocates to push the arc-shaped guide plate, causing the elastic airbag to reciprocate to compress and recover. Air is then reciprocated to be drawn in and discharged through the connected intake and exhaust processing section.

[0012] Preferably, the intake and exhaust assembly further includes an outer frame, a support guide plate, and a connecting port. The support guide plate is fixed in the outer frame, the elastic airbags are symmetrically distributed and fixed on both sides of the support guide plate, and the elastic airbags are sleeved in the outer frame. The connecting port is opened in the support guide plate, and the two ends of the connecting port are respectively connected to the elastic airbags and the intake and exhaust processing unit.

[0014] Preferably, workbenches are fixedly provided on both sides of the outer frame of the container, and operating ports are opened on both sides of the outer frame of the container.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) This invention utilizes the rotation of the composite control component and the reciprocating movement of the movable frame, and with the elastic deformation of the spring, the movable frame drives the front elastic layer to move closer to the outside of the boxed goods, and achieves intermittent contact sealing. With the suction action of the suction pump, adsorption and fixation are achieved during elastic contact, quickly achieving side adsorption and fixation of the boxed goods. The adsorption and fixation position is elastically adsorbed. For boxed goods, under side contact adsorption, the rigid clamping effect on the deformation of the boxed goods is effectively reduced, achieving protective clamping, improving the clamping and transportation stability of the boxed goods during the same layer double extraction process, and avoiding damage and deformation of the boxed goods.

[0017] (2) This invention reuses the composite control component, which is then matched with the suction and exhaust component after the composite control component is reset. Under the rotation of the composite control component, the suction and exhaust component is reciprocated to compress and suck air. During the compression process, it works with the suction and exhaust treatment unit to blow air and complete the blowing and cleaning of the outside of the boxed goods. During the suction stage of the suction and exhaust component, the flying dust is instantly sucked into the suction and exhaust treatment unit and filtered and collected. While cleaning the surface of the boxed goods, the instantaneous suction and collection are completed simultaneously, preventing the blown dust from falling into the inside of the double-row shelf and achieving internal cleanliness maintenance.

[0018] (3) The present invention, by cooperating with the reset rotation of the composite control component and the reset adsorption gripping part on the other side, while the composite control component rotates and controls the suction and exhaust component to reciprocate suction and exhaust, the cam rotates to the other side to reciprocate control the movement of the movable frame. When the suction pump stops suction, the reciprocating movable frame drives the elastic layer to reciprocate against the outside of the boxed goods. In conjunction with the above suction and exhaust process, the reciprocating vibration process under suction and exhaust dust removal is realized, which further improves the removal effect of the attached objects on the outside of the boxed goods.

[0031] 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.

[0032] like Figures 1 to 11As shown, this embodiment of the invention provides a vertical lift storage unit for a multi-level warehouse with dual retrieval systems. It includes a storage unit frame 1, double-row shelves 2 embedded within the storage unit frame 1, and a lifting mechanism 3 disposed within the storage unit frame 1. The double-row shelves 2 have a storage / retrieval platform 6 inside. Support components 7 are symmetrically arranged on the top of the storage / retrieval platform 6. A movable arm 8 is elastically sleeved inside the support component 7. An adsorption gripping part 9 is fixedly provided on the end face of the movable arm 8. A buffer moving part is provided on the outside of the adsorption gripping part 9. A composite control component 10 is provided at the end of the movable arm 8. An exhaust suction assembly 11 is fixedly installed on the outside of the support assembly 7. An exhaust suction treatment section 12 is provided on the front of the support frame assembly. An air pump 17 is provided at the bottom of the storage and retrieval moving platform 6. The air pump 17 controls the moving arm 8 to extend and retract through the support assembly 7. The composite control assembly 10 drives the adsorption gripping section 9 and the buffer moving section to complete the contact adsorption and fixation of the outer side of the goods. The composite control assembly 10 reciprocates to compress the exhaust suction assembly 11 and repeatedly blows and sucks in the air near the stored goods through the exhaust suction treatment section 12 connected to the exhaust suction assembly 11.

[0033] Example 1: In use, the cardboard boxes to be stored are placed into the retrieval area of ​​the double-row shelf 2 along the operating port 5. At this time, the control terminal, in conjunction with the lifting mechanism 3, moves the storage and retrieval mobile platform 6 to the bottom of the double-row shelf 2 and aligns it with the operating port 5. The air pump 17 is started, and pressurized air is input into the interior of the support component 7 and into the support frame 71 through the connecting air passage 74. The internal air pressure increases, pushing the moving arm 8 to move laterally. As the four sets of moving arms 8 move synchronously, the suction gripping part 9 moves synchronously, so that the suction gripping part 9 moves to the outside of the boxed goods. The suction pump 93 in the suction gripping part 9 is started. The suction pump 93 sucks the air inside the movable frame 92 and draws in air through the air suction hole 94 and the connecting hole on the elastic layer 13. At the same time, the composite control component 10 on the moving arm 8 is started, and the cam is driven by the motor 101. When cam 102 rotates, it pushes the movable frame 92 along the guide arc surface 15 on the movable frame 92, causing the movable frame 92 to stretch the spring 14 and slide along the assembly frame 91. During the intermittent sliding process, the front of the elastic layer 13 contacts the side of the boxed goods. When in contact, the boxed goods are adsorbed onto the front of the movable frame 92 under negative pressure, completing the adsorption and fixation. As the air pump 17 removes the air pressure, the outer moving arm 8 elastically resets and synchronously moves the boxed goods held by both sides to the top of the storage and retrieval moving platform 6 and onto the top of the guide roller 16. With the control terminal cooperating with the lifting mechanism 3, the storage and retrieval moving platform 6 rises and moves to the designated position. The air pump 17 starts again and, in cooperation with the moving arm 8, transports the adsorbed boxed goods to the double-row shelf 2 to complete the storage process. The same process can be used to retrieve the goods.

[0034] First, by utilizing the rotation of the composite control component 10 and reciprocatingly pushing the movable frame 92 to move, and in conjunction with the elastic deformation of the spring 14, the movable frame 92 drives the front elastic layer 13 to move closer to the outside of the boxed goods, achieving intermittent contact sealing. In conjunction with the suction action of the suction pump 93, adsorption and fixation are achieved during elastic contact, quickly realizing the side adsorption and fixation of the boxed goods. The elastic adsorption at the fixation position effectively reduces the deformation impact of rigid clamping on the boxed goods under side contact adsorption, achieving protective clamping, improving the clamping and transportation stability of the boxed goods during the same-layer double extraction process, and avoiding damage and deformation of the boxed goods.

[0035] Example 2: When storing boxed goods, as the goods are picked up and fall onto the top of the storage and retrieval moving platform 6, the four sets of moving arms 8 reset and are fitted into the support assembly 7. At this time, the composite control assembly 10 is activated again, the cam 102 rotates and intermittently pushes the arc-shaped guide plate 116 in the suction and exhaust treatment section 12, and the push causes the arc-shaped guide plate 116 to compress the elastic airbag 113 through the connecting rod 115 and the connecting plate 114, so that the air in the elastic airbag 113 passes through the connecting port 117, the assembly connecting cavity 121 and the suction and exhaust. Air vent 123 blows out, causing compressed air to blow towards the surface of the boxed goods, and dust flies up. As cam 102 moves away from arc guide plate 116, elastic airbag 113 elastically returns to its original state, and the flying dust is re-inhaled into assembly connecting cavity 121 through intake and exhaust vent 123. The dust is filtered in filter element 122, and the filtered air is refilled into elastic airbag 113. As cam 102 rotates, the dust on the outside of the boxed goods is blown out and simultaneously sucked in.

[0036] First, by reusing the composite control component 10, after the composite control component 10 is reset, it cooperates with the suction and exhaust component 11. Under the rotation of the composite control component 10, the suction and exhaust component 11 is reciprocated to compress and suck air. During the compression process, it cooperates with the suction and exhaust treatment unit 12 to blow air and complete the blowing and cleaning of the outside of the boxed goods. During the suction phase of the suction and exhaust component 11, the flying dust is instantly sucked into the suction and exhaust treatment unit 12 and filtered and collected. While cleaning the surface of the boxed goods, the instantaneous suction and collection are completed simultaneously, preventing the blown dust from scattering inside the double-row shelf 2 and achieving internal cleanliness maintenance.

[0037] Furthermore, by cooperating with the reset rotation of the composite control component 10 and the reset adsorption gripping part 9 on the other side, while the composite control component 10 rotates and controls the suction and exhaust component 11 to reciprocate suction and exhaust, the cam 102 reciprocates to control the movement of the movable frame 92 when it rotates to the other side. When the suction pump 93 stops suction, the reciprocating movable frame 92 drives the elastic layer 13 to reciprocate to contact the outside of the boxed goods. In conjunction with the above suction and exhaust process, the reciprocating vibration process under suction and exhaust dust removal is realized, further improving the removal effect of the attached objects on the outside of the boxed goods.

[0038] The support assembly 7 includes a support frame 71, a middle partition 72, a bottom frame 73, and a connecting air passage 74. The middle partition 72 is fixed inside the support frame 71, the bottom frame 73 is fixed to the top of the access moving platform 6, and the upper end of the bottom frame 73 is fixedly connected to the support frame 71. The connecting air passage 74 is opened in the bottom frame 73. The access moving platform 6 has a middle air passage inside. The air pump 17 inputs pressurized air into the support frame 71 through the middle air passage and the connecting air passage 74. The top of the access moving platform 6 is provided with a guide roller 16.

[0039] The support component 7 supports the movable arm 8 and works with the air pump 17 to push the movable arm 8 under the input of pressurized air. The movable arm 8 is elastically connected by the second spring, and the inner end of the movable arm 8 is provided with a reserved cavity to ensure the assembly space of the second spring.

[0040] The composite control component 10 includes a motor 101 and a cam 102. The motor 101 is fixed on the moving arm 8, and the cam 102 is fixed on the output shaft of the motor 101. The adsorption gripping part 9 and the suction and exhaust assembly 11 are located on both sides of the cam 102.

[0041] The composite control component 10 rotates to achieve reciprocating control of the adsorption gripping part 9 and the suction and exhaust component 11 on both sides.

[0042] The adsorption and gripping part 9 includes an assembly frame 91, a movable frame 92, a suction pump 93, and a suction hole 94. The movable frame 92 is movably installed in the assembly frame 91. The suction pump 93 is fixed to the top of the movable frame 92 and draws gas from inside the movable frame 92. The suction hole 94 is opened on the front of the movable frame 92 and is connected to the movable frame 92. The buffer moving part includes an elastic layer 13, a spring 14, and a guide arc surface 15. The elastic layer 13 is fixed on the front of the movable frame 92 and has a connecting hole. The connecting hole is connected to the suction hole 94 one by one. One end of the spring 14 is fixed to the side of the movable frame 92 through a connecting block, and the other end of the spring 14 is fixedly connected to the assembly frame 91, so that the movable frame 92 is elastically fitted in the assembly frame 91. The guide arc surface 15 is opened at one corner of the side of the movable frame 92, and the position of the guide arc surface 15 is adapted to the position of the cam 102.

[0043] The adsorption gripping part 9 and the buffer moving part work together to achieve elastic buffer adsorption gripping. With the rotation of the cam 102, the elastic layer 13 is intermittently controlled to reciprocate in contact with the boxed goods. When in contact, the negative pressure suction effect is used to achieve adsorption gripping. There is no need to add a clamping and moving control device. While reserving elastic compression space, adsorption gripping can be achieved quickly. During adsorption, the movable frames 92 on both sides are pulled in synchronously to ensure the structural stability of the boxed goods.

[0044] The intake and exhaust assembly 11 includes an elastic airbag 113, a connecting plate 114, a connecting rod 115, and an arc-shaped guide plate 116. The connecting rod 115 is fixed between the connecting plate 114 and the arc-shaped guide plate 116. The connecting plate 114 is fixed on the elastic airbag 113. The position of the arc-shaped guide plate 116 is adapted to the cam 102. When the cam 102 approaches the arc-shaped guide plate 116 and rotates, the cam 102 reciprocates by pushing the arc-shaped guide plate 116, causing the elastic airbag 113 to reciprocate by compression and recovery. The intake and exhaust processing section 12 reciprocates to draw in and exhaust air. The intake and exhaust assembly 11 also includes an outer frame 111, a support guide plate 112, and a connecting port 117. The support guide plate 112 is fixed in the outer frame 111. Elastic airbags 113 are symmetrically distributed and fixed on both sides of the support guide plate 112, and the elastic airbags 113 are sleeved in the outer frame 111. The connecting port 117 is opened in the support guide plate 112, and the two ends of the connecting port 117 are respectively connected to the elastic airbags 113 and the intake and exhaust processing section 12.

[0045] The intake and exhaust of external air is achieved by repeatedly compressing and restoring the elastic airbag 113 in the intake and exhaust assembly 11. During exhaust, it is used for purging, and during intake, it is used for dust intake. The arc-shaped guide plate 116 is adapted to the cam 102 to achieve the lateral movement of the arc-shaped guide plate 116 under intermittent squeezing and pushing, and the compression and restoration of the elastic airbag 113 are completed under the reciprocating lateral movement.

[0046] The intake and exhaust treatment unit 12 includes an assembly communication cavity 121, a filter element 122, and an intake and exhaust port 123. The assembly communication cavity 121 is opened inside the support frame 71, the filter element 122 is fixed in the assembly communication cavity 121, and the intake and exhaust port 123 is opened on the front of the support frame 71 and is connected to the assembly communication cavity 121.

[0047] The intake and exhaust treatment unit 12 filters the intake air and, together with the filter element 122, collects and separates dust to reduce environmental dust.

[0048] The outer frame 1 of the container is equipped with workbenches 4 on both sides, and operation ports 5 are opened on both sides of the outer frame 1 of the container.

[0049] The working principle and usage process of this invention are as follows: In use, the cardboard boxes to be stored are placed along the operating opening 5 into the retrieval area of ​​the double-row shelf 2. At this time, the control terminal, in conjunction with the lifting mechanism 3, moves the storage and retrieval mobile platform 6 to the bottom of the double-row shelf 2 and aligns it with the operating opening 5. The air pump 17 is activated, and pressurized air is input into the support assembly 7 and then into the support frame 71 through the connecting air passage 74. The internal air pressure increases, pushing the moving arms 8 to move laterally. As the four sets of moving arms 8 move synchronously, the suction gripping part 9 moves synchronously, causing the suction gripping part 9 to move to the outside of the boxed goods. The suction pump 93 in the suction gripping part 9 is activated, and the suction pump 93 sucks the movable frame 9. 2. Internal air is drawn in through the air intake 94 and the connecting holes on the elastic layer 13. Simultaneously, the composite control component 10 on the moving arm 8 is activated. As the motor 101 drives the cam 102 to rotate, the cam 102 rotates and pushes the moving frame 92 along the guide arc surface 15 on the moving frame 92. This causes the moving frame 92 to stretch the spring 14 and slide along the assembly frame 91. During the intermittent sliding process, the front of the elastic layer 13 contacts the side of the boxed goods. When in contact, the boxed goods are adsorbed onto the front of the moving frame 92 under negative pressure, completing the adsorption and fixation. As the air pump 17 removes the air pressure, the outer moving arm 8 elastically resets and clamps the box held on both sides. The loaded goods are simultaneously moved to the top of the storage and retrieval moving platform 6 and land on the top of the guide roller 16. With the control terminal cooperating with the lifting mechanism 3, the storage and retrieval moving platform 6 rises and moves to the designated storage position. The air pump 17 starts again, cooperating with the moving arm 8 to transport the boxed goods held by the suction to the double-row shelf 2, completing the storage process. The same process can be used to retrieve the goods. When storing boxed goods, as the goods are grabbed and land on the top of the storage and retrieval moving platform 6, the four sets of moving arms 8 reset and are put into the support assembly 7. At this time, the composite control assembly 10 is started again. The cam 102 rotates and intermittently pushes and squeezes the arc-shaped guide plate 116 in the suction and exhaust treatment section 12. Under the push, the arc-shaped guide plate 116 passes through the connecting rod. 115 and connecting plate 114 compress the elastic airbag 113, causing the air in the elastic airbag 113 to be blown out through the connecting port 117, the assembly connecting cavity 121 and the suction and exhaust port 123, so that the compressed air blows towards the surface of the boxed goods, and the surface dust flies up. As the cam 102 moves away from the arc-shaped guide plate 116, the elastic airbag 113 elastically recovers and the flying dust is sucked back into the assembly connecting cavity 121 through the suction and exhaust port 123. The dust is filtered in the filter element 122, and the filtered air is refilled into the elastic airbag 113. As the cam 102 rotates, the dust on the outside of the boxed goods is blown and cleaned and simultaneously sucked in.
