Description

Technical Field

[0001] This invention relates to the field of storage device technology, specifically to a rotary cabinet with multi-storage independent cabinet doors and its usage method. Background Technology

[0002] Rotary storage cabinets (also known as rotating cabinets or rotary intelligent storage equipment) are automated storage devices widely used in fields such as document management, tool storage, pharmaceutical management, and electronic component storage. They utilize a rotating mechanism to drive the storage compartments in a vertical, cyclical motion, automatically rotating the target storage location to the retrieval port in front of the operator, achieving high-density storage and rapid access.

[0003] The existing rotary cabinets have only one large door on the front, which is shared by all storage compartments for retrieval. This structure requires opening the entire door for each access, exposing non-target storage compartments to the external environment. Frequent opening of the large door causes drastic fluctuations in the internal temperature and humidity, which is detrimental to the long-term preservation of temperature and humidity-sensitive items (such as archives, medicines, and precision electronic components). At the same time, the large opening area of ​​the door increases the risk of lost items and information security.

[0004] Meanwhile, cabinet doors with multiple storage positions often share a single drive mechanism, making it impossible to achieve truly independent control. When the drive mechanism fails, the storage position will be unable to operate normally. Furthermore, the connection between the cabinet door and the drive mechanism is mostly rigidly fixed, lacking height adjustment and alignment compensation mechanisms. When the position of the retrieval port of the rotating cabinet door plate is slightly offset due to manufacturing tolerances, long-term load deformation, or installation errors, problems such as misalignment, jamming, or poor sealing may easily occur between the cabinet door and the retrieval port.

[0005] Furthermore, as intelligent warehousing systems evolve towards high-density, multi-user collaboration, and refined management, the market is placing higher demands on rotary storage cabinets: each storage location must possess independent physical isolation and access control capabilities; the cabinet door opening and closing mechanism must be flexible and adjustable to adapt to the needs of different sized containers and access ports. Existing technologies have failed to fully meet these requirements.

[0006] Therefore, we propose a multi-storage independent cabinet door structure for rotary cabinets and its usage method. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-storage independent cabinet door structure for rotary cabinets and its usage method, in order to solve the shortcomings of the prior art, where cabinet doors with multiple storage locations often share a single drive mechanism, making it impossible to achieve truly independent control, and where the connection between the cabinet door and the drive mechanism is mostly rigidly fixed, lacking height adjustment and alignment compensation mechanisms.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rotary cabinet with multi-storage independent cabinet doors, comprising:

[0009] The rotary cabinet door panel has multiple sets of loading and unloading openings.

[0010] A container is located on the back side of the rotary cabinet door panel and is connected to the corresponding loading and unloading port;

[0011] A cabinet door is provided at the retrieval opening for opening and closing the retrieval opening;

[0012] An opening and closing mechanism is provided above the cabinet door and connected to the cabinet door drive, and is used to independently drive each cabinet door to move in the vertical direction to open and close the corresponding take-out and put-out openings.

[0013] The control unit is electrically connected to the opening and closing mechanism and is used to independently control the opening and closing actions of each of the opening and closing mechanisms.

[0014] Preferably, the back side of the rotary cabinet door is provided with vertical guide rails on both sides of the loading and unloading opening, and the cabinet door is provided with corresponding sliding plates on both sides. The sliding plates slide in cooperation with the vertical guide rails so that the cabinet door can move vertically along the vertical guide rails.

[0015] Preferably, a reinforcing rib is provided in the middle of the cabinet door, and a connecting seat plate is provided at the top of the reinforcing rib. The output end of the opening and closing mechanism is connected to the cabinet door through the connecting seat plate.

[0016] Preferably, the opening and closing mechanism includes an electric push rod, which is positioned directly above the retrieval port. The output end of the electric push rod is connected to the cabinet door via a connecting base plate to drive the cabinet door to move vertically to open and close the retrieval port.

[0017] Preferably, the control unit is a PLC controller, which is electrically connected to each of the electric push rods and is used to independently control the extension and retraction movement of each of the electric push rods to independently open and close each of the pick-up and put-out ports.

[0018] Preferably, it further includes a height adjustment component, the height adjustment component comprising:

[0019] A fixed bracket is installed on the rotary cabinet door panel by a fixing bolt, and the fixed bracket has mounting holes;

[0020] The support frame, connected to the electric push rod via height adjustment bolts, is used to support the opening and closing mechanism;

[0021] A height adjustment mechanism is provided between the fixed bracket and the support frame to adjust and fix the height position of the support frame relative to the fixed bracket.

[0022] Preferably, the height adjustment mechanism includes:

[0023] A connecting bracket includes a support rod and sliding cylinders disposed at both ends of the support rod;

[0024] A fixed sleeve is disposed in the mounting hole of the fixed bracket, and the sliding cylinder is slidably sleeved on the inner wall side of the fixed sleeve;

[0025] A positioning spring is disposed inside the fixed sleeve and located on the outer periphery of the slide cylinder, and is used to apply an elastic positioning force to the slide cylinder;

[0026] A positioning plate is connected to the outer periphery of the slide cylinder via a support rod, and a positioning protrusion is provided at the end of the positioning plate;

[0027] The support frame has adjustment grooves on both sides, and multiple sets of positioning holes are provided on both sides of the adjustment grooves. The positioning protrusions engage with the positioning holes to fix the height of the support frame.

[0028] Preferably, a connecting groove is provided in the mounting hole, and the fixing sleeve is embedded in the mounting hole through the connecting groove.

[0029] Preferably, the fixed bracket is provided with a vertical guide rail, and the support frame is provided with a corresponding slide rail. The slide rail slides in cooperation with the vertical guide rail so that the support frame can move vertically relative to the fixed bracket.

[0030] A method for using a rotary cabinet with multi-storage independent cabinet doors includes the following steps:

[0031] S1: Fixed bracket installation

[0032] The fixing bracket is attached to the installation area above the loading and unloading port on the rotary cabinet door panel, and the fixing bracket is fastened to the rotary cabinet door panel by passing the fixing bolt through the mounting hole;

[0033] S2: Fixed sleeve installation

[0034] The fixed sleeve is connected to the bracket and embedded in the mounting hole through the connecting groove, so that the outer end face of the fixed sleeve is flush with the surface of the fixed bracket.

[0035] S3: Support frame connection

[0036] Connect the support frame to the electric push rod via the height adjustment bolt, align the adjustment groove of the support frame with the fixed sleeve, and snap the positioning protrusion of the positioning plate into the positioning holes on both sides of the adjustment groove to complete the initial fixation of the support frame and the fixed bracket.

[0037] S4: Coarse Alignment

[0038] Pull the frame rod to move the slide cylinder along the inner wall of the fixed sleeve and squeeze the positioning spring, causing the positioning protrusion to disengage from the current positioning hole. Move the support frame along the adjustment groove to the target height and then release it. Push the support frame to make the slide slide along the vertical slide rail. Adjust the alignment accuracy between the electric push rod and the pick-up / place-out port so that the output end of the electric push rod is aligned with the connecting seat plate of the cabinet door. Then release the pulling action on the frame rod to reset the positioning spring and make the positioning protrusion engage with the corresponding positioning hole, thus completing the height fixation of the support frame.

[0039] S5: High-level fine-tuning

[0040] Loosen the nut at the top of the height adjustment bolt, then turn the height adjustment bolt. The height adjustment bolt pushes the electric push rod down through the threaded connection until the electric push rod connects to the cabinet door and completely closes the loading and unloading opening.

[0041] S6: System Initialization

[0042] Start the PLC controller to perform origin reset calibration on each electric push rod and establish the corresponding mapping relationship between the storage position code of each pick-up and put-out port and the electric push rod;

[0043] S7: Receive access command

[0044] During use, the PLC controller receives the target storage location code and start / stop command from the external input, and determines the target electric push rod according to the corresponding mapping relationship.

[0045] S8: Independent opening and closing control

[0046] The PLC controller sends a drive signal to the target electric push rod. After receiving the drive signal, the target electric push rod performs a telescopic movement, which drives the corresponding cabinet door to move vertically along the vertical guide rail through the connecting base plate, and independently opens and closes the target pick-up and drop-off port.

[0047] In the above technical solution, the rotary cabinet multi-storage independent cabinet door structure and its usage method provided by the present invention have the following beneficial effects:

[0048] 1. This device uses independently installed electric actuators above each set of loading and unloading ports as opening and closing mechanisms. Each actuator is independently electrically connected and controlled by a PLC controller, ensuring complete decoupling of the opening and closing actions of each storage location at both the mechanical and electrical control levels. The resulting benefits are: multiple users can simultaneously issue access commands to different storage locations, and the system can schedule each electric actuator to independently execute opening and closing actions without interference, significantly improving the rotary cabinet's concurrent processing capacity and operational efficiency; simultaneously, a failure of a single electric actuator only affects the corresponding storage location and will not affect the normal operation of other storage locations, greatly improving the overall reliability and maintainability of the system.

[0049] 2. By creating multiple access ports on the rotary cabinet door panel and configuring an independent door for each port, each storage compartment forms an independent physical isolation space. This ensures that opening or closing a single storage compartment only exposes the corresponding compartment, while the remaining compartments remain closed. This effectively reduces air exchange between the cabinet and the external environment, significantly reducing temperature and humidity fluctuations and providing stable environmental conditions for the long-term preservation of sensitive items. Simultaneously, the significantly reduced opening area effectively controls the risks of item loss and information leakage, making it particularly suitable for applications with high security requirements, such as document management, pharmaceutical storage, and storage of high-value electronic components.

[0050] 3. This invention incorporates a height adjustment component, configuring a height adjustment mechanism between the fixed bracket and the support frame. Coarse height adjustment is achieved through the sliding fit between the connecting bracket's sliding cylinder and the fixed sleeve, the elastic positioning force of the positioning spring, and the snap-fit ​​between the positioning plate and the positioning hole. Fine height adjustment is achieved through the threaded transmission of the height adjustment bolt. This allows for rapid adjustment of the vertical position of the support frame (and electric push rod) within a large range, and precise compensation for alignment deviations within a small range, ensuring that the output end of the electric push rod remains accurately aligned with the cabinet door connecting plate. It fundamentally eliminates problems such as cabinet door misalignment, movement jamming, and inadequate sealing caused by manufacturing tolerances, installation errors, and long-term deformation, ensuring smooth movement of the cabinet door along the vertical guide rail and reliable contact with the edge of the access opening when closed.

[0079] A positioning spring 544 is disposed inside the fixed sleeve 543 and located on the outer periphery of the slide cylinder 542, and is used to apply an elastic positioning force to the slide cylinder 542;

[0082] Furthermore, a connecting groove 548 is provided in the mounting hole 511, and the fixing sleeve 543 is embedded in the mounting hole 511 through the connecting groove 548.

[0083] The fixed bracket 51 is provided with a vertical guide rail 12, and the support frame 52 is provided with a corresponding slide rail 5410. The slide rail 5410 slides in cooperation with the vertical guide rail 12 so that the support frame 52 can move vertically relative to the fixed bracket 51.

[0084] A method for using a rotary cabinet with multi-storage independent cabinet doors includes the following steps:

[0085] S1: Mounting of bracket 51

[0086] The fixing bracket 51 is attached to the installation area of ​​the rotary cabinet door panel 1 above the loading and unloading port 11, and the fixing bracket 51 is fastened to the rotary cabinet door panel 1 by passing the fixing bolt 512 through the mounting hole 511.

[0087] S2: Fixed sleeve 543 is embedded

[0088] The fixing sleeve 543 is connected to the connecting bracket 541 and embedded in the mounting hole 511 through the connecting groove 548, so that the outer end face of the fixing sleeve 543 is flush with the surface of the fixing bracket 51.

[0089] S3: Connector 52

[0090] Connect the support frame 52 to the electric push rod 41 via the height adjustment bolt 53, align the adjustment groove 546 of the support frame 52 with the fixed sleeve 543, and snap the positioning protrusion 5451 of the positioning plate 545 into the positioning holes 547 on both sides of the adjustment groove 546 to complete the initial fixation of the support frame 52 and the fixed bracket 51.

[0091] S4: Coarse Alignment

[0092] Pulling the support rod 5411 causes the slide cylinder 542 to move along the inner wall of the fixed sleeve 543 and squeeze the positioning spring 544, causing the positioning protrusion 5451 to disengage from the current positioning hole 547. After moving the support frame 52 to the target height along the adjustment groove 546, it is released. Pushing the support frame 52 causes the slide rail 5410 to slide along the vertical slide rail 549. Adjust the alignment accuracy of the electric push rod 41 and the pick-up and put-out port 11 so that the output end of the electric push rod 41 is aligned with the connecting seat plate 33 of the cabinet door 3. Then, release the pulling action on the support rod so that the positioning spring 544 resets and the positioning protrusion 5451 is inserted into the corresponding positioning hole 547, thus completing the height fixation of the support frame 52.

[0093] S5: High-level fine-tuning

[0094] Loosen the nut at the top of the height adjustment bolt 53, and then rotate the height adjustment bolt 53. The height adjustment bolt 53 pushes the electric push rod 41 down through the threaded connection until the electric push rod 41 connects to the cabinet door 3 and completely closes the take-out opening 11.

[0095] S6: System Initialization

[0096] Start the PLC controller to perform origin reset calibration on each electric push rod 41 and establish the corresponding mapping relationship between the storage position code of each pick-up and put-out port 11 and the electric push rod 41.

[0097] S7: Receive access command

[0098] During use, the PLC controller receives the target storage location code and opening / closing command from the external input, and determines the target electric push rod 41 according to the corresponding mapping relationship;

[0099] S8: Independent opening and closing control

[0100] The PLC controller sends a drive signal to the target electric push rod 41. After receiving the drive signal, the target electric push rod 41 performs a telescopic movement, which drives the corresponding cabinet door 3 to move vertically along the vertical guide rail 12 through the connecting base plate 33, and independently opens and closes the target pick-up and drop-off port 11.

[0101] A rotary cabinet with multi-storage independent door structure and its usage method have the following beneficial effects:

[0102] 1. This device uses independently installed electric actuators above each set of loading and unloading ports as opening and closing mechanisms.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.

S2: Fixed sleeve (543) embedded The fixing sleeve (543) is connected to the connecting bracket (541) and embedded in the mounting hole (511) through the connecting groove (548), so that the outer end face of the fixing sleeve (543) is flush with the surface of the fixing bracket (51); S3: Support frame (52) connection Connect the support frame (52) to the electric push rod (41) through the height adjustment bolt (53), so that the adjustment groove (546) of the support frame (52) is aligned with the fixed sleeve (543), and the positioning protrusion (5451) of the positioning plate (545) is snapped into the positioning holes (547) on both sides of the adjustment groove (546) to complete the initial fixation of the support frame (52) and the fixed bracket (51); S4: Coarse Adjustment Pull the frame rod (5411) to move the slide cylinder (542) along the inner wall of the fixed sleeve (543) and squeeze the positioning spring (544), so that the positioning protrusion (5451) is disengaged from the current positioning hole (547). Move the support frame (52) along the adjustment groove (546) to the target height and then release it. Push the support frame (52) to make the slide rail (5410) slide along the vertical slide rail (549). Adjust the alignment accuracy of the electric push rod (41) and the pick-up and put-out port (11) so that the output end of the electric push rod (41) is aligned with the connecting seat plate (33) of the cabinet door (3). Then release the pulling action on the frame rod so that the positioning spring (544) resets and the positioning protrusion (5451) is inserted into the corresponding positioning hole (547) to complete the height fixation of the support frame (52). S5: High-level fine-tuning Loosen the nut at the top of the height adjustment bolt (53), and then rotate the height adjustment bolt (53). The height adjustment bolt (53) pushes the electric push rod (41) down through the threaded connection until the electric push rod (41) connects to the cabinet door (3) and completely closes the take-out opening (11). S6: System Initialization Start the PLC controller, perform origin reset calibration on each electric push rod (41), and establish the corresponding mapping relationship between the storage position code of each pick-up and put-out port (11) and the electric push rod (41); S7: Receive access command During use, the PLC controller receives the target storage location code and opening / closing command from the external input, and determines the target electric push rod (41) according to the corresponding mapping relationship. S8: Independent opening and closing control The PLC controller sends a drive signal to the target electric push rod (41). After receiving the drive signal, the target electric push rod (41) performs a telescopic movement, which drives the corresponding cabinet door (3) to move vertically along the vertical guide rail (12) through the connecting seat plate (33), and independently opens and closes the target pick-up and drop-off port (11).
