Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stereoscopic warehouse, and in particular to a storage automated stereoscopic warehouse. BACKGROUND

[0002] In the field of plastic bottle production, the storage quality and management efficiency of raw materials (such as PET granules, color master batches, etc.) directly affect the production continuity and product quality. At present, the industry often uses automated stereoscopic warehouses to realize large-scale storage of different types of raw materials. The storage space is arranged in a matrix of warehouse racks, and a palletizing robot is used to complete the transfer of raw materials in the reserved channel to improve the space utilization and the level of automation. The existing stereoscopic warehouse often focuses on physical handling and location management, and the real-time monitoring capability of the raw material state (such as humidity, temperature, inventory, etc.) is insufficient, and manual intervention is still needed for box opening inspection or relies on fixed environmental sensors, which cannot effectively monitor the internal condition of the raw material. For example, Patent No. CN222947438U - Chinese Utility Model Patent Stereoscopic Warehouse, paragraph 0105 of the patent discloses that a temperature sensor can be provided in each accommodation cavity to detect the temperature in the current accommodation cavity and send the detection result to the controller. Although it is mentioned that a temperature sensor is provided in the accommodation cavity of the shelf, the detection object is the cavity environment rather than the raw material itself. Similarly, another patent No. CN215930253U - Chinese Utility Model Patent A stereoscopic warehouse with temperature and humidity control function, the patent discloses that "a sensor group for monitoring humidity and temperature is arranged in the inside of each layer of storage column, and the sensor group includes a temperature sensor and a humidity sensor for measuring the temperature and humidity inside the library body respectively". It describes that a temperature and humidity sensor group is arranged in each layer of storage column, which still belongs to space level monitoring and cannot be embedded in the internal condition of the raw material for in-situ measurement, so it is difficult to truly reflect the actual state of the material. In addition, the existing stereoscopic warehouse also has certain limitations in terms of sealing, especially when storing plastic raw materials that are easily affected by the environment. The simple cover structure cannot effectively prevent moisture and dust, affecting the stability of the raw material. SUMMARY

[0003] The main purpose of the present application is to provide a storage automated stereoscopic warehouse to solve the problem that the existing automated stereoscopic warehouse often focuses on physical handling and location management, and the real-time monitoring capability of the raw material state is insufficient, and manual intervention is still needed for box opening inspection or relies on fixed environmental sensors, which cannot realize independent and accurate monitoring of the internal condition of each raw material turnover box.

[0013] The bottom end of the fixed plate is fixedly connected with the moving plate, and the top end of the lifting plate is fixedly connected with one end of the horizontally arranged sealing cover.

[0014] The two hinged plates are arranged in parallel along the height direction of the storage box, and the two ends of each hinged plate are hingedly connected with the fixed plate and the lifting plate respectively.

[0015] The flat plate is fixedly arranged on the inner side wall of the storage box, and a Z-shaped groove is formed in the flat plate, and the flat plate is located directly above the straight rail.

[0016] A guide column is fixedly arranged on the upper hinged plate, one end of the guide column away from the hinged plate is movably inserted into the Z-shaped groove, and the guide column is located in the upper middle part of the upper hinged plate.

[0017] An opening is formed in the bottom wall of the storage box, and the opening is in communication with the opening.

[0018] One preferred scheme is that an L-shaped plate is fixedly arranged on the top wall of the moving plate, one end of the L-shaped plate away from the moving plate is located in the position directly above the notch, and the two sides form an insertion space, and the insertion space, the notch and the opening are sequentially communicated from top to bottom.

[0019] The lifting plate is fixed on the palletizing robot, and the pulling plate is fixed on the lifting plate.

[0020] The bottom wall of the moving plate is fixedly connected with the mounting plate.

[0021] The scanning gun is mounted on the lifting plate.

[0022] In a preferred scheme, the sealing cover is a rectangular plate body, a containing groove is formed in the bottom wall of the rectangular plate body, and a flexible plate is filled in the containing groove, and the flexible plate can be covered on the turnover box.

[0023] In a preferred scheme, each storage box is further provided with a clamping unit, and the clamping unit comprises a lead screw, a guide rod and two clamping arms.

[0024] The lead screw and the guide rod are arranged along the width direction of the storage box, and the two clamping arms are sleeved with the lead screw and the guide rod, the top ends of the two clamping arms are slidingly arranged on the guide rod, and the two clamping arms are located on the storage box and between the opening and the control unit.

[0028] The above scheme has the following beneficial effects:

As the sealing cap moves via a lifting control unit, the sensors dynamically insert into the storage box, enabling real-time parameter acquisition for each individual raw material unit. A data terminal receives and processes the sensor data in real time, constructing a "one box, one file" digital monitoring system, completely resolving the monitoring lag and data fragmentation issues caused by traditional warehouses relying on manual sampling or fixed sensors. The sealing cap and storage box form a relatively sealed space, effectively isolating external environmental interference such as humidity and dust, making it particularly suitable for plastic raw materials such as PET granules and masterbatches that are susceptible to environmental influences. Compared to traditional open storage or simple lid structures, this solution significantly improves raw material storage stability through active sealing design, reducing problems such as raw material oxidation, clumping, and color crosstalk caused by environmental factors, ensuring consistent product quality in subsequent blow molding. The data terminal, sensors, and control unit form a closed-loop control system, reducing raw material loss and minimizing the frequency of manual intervention through sealed storage and precise monitoring.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] First embodiment:

[0043] like Figures 1-8 As shown, this embodiment provides an automated storage and retrieval system (AS / RS), including two symmetrically arranged storage racks 1, with a retrieval aisle 3 reserved between the two racks for a palletizing robot 2 to move through. Multiple rectangular storage boxes 4 are fixedly mounted on each rack 1 in a matrix. One side of each storage box 4 has an opening 40 facing the retrieval aisle 3. A sealing cover 5 for covering a turnover box 10 is provided inside each storage box 4. The sealing cover 5 is connected to a control unit 51 for moving and lifting the turnover box. The existing turnover box 10 is a rectangular box with an open top (i.e., the top of the rectangular turnover box is an open structure), such as... Figure 7 As shown, the sealing cover 5 is equipped with multiple sensors 52, which are material level sensors, humidity sensors, or temperature sensors. These sensors 52 can be inserted into the turnover box 10 by raising and lowering the sealing cover 5, and all sensors 52 communicate with the data terminal 6, which is a PC computer.

[0044] The sealing cover 5 integrates multiple sensors 52 (such as humidity, temperature, and material level sensors). When the sealing cover 5 is moved by the lifting control unit 51, the sensors 52 can be dynamically inserted into the turnover box 10 to achieve real-time parameter acquisition for each independent raw material unit. The data terminal 6 receives and processes the data from the sensors 52 in real time, constructing a "one box, one file" digital monitoring system, completely solving the problems of monitoring lag and data dispersion caused by traditional warehouses relying on manual sampling or fixed sensors 52. The sealing cover 5 and the storage box 4 form a relatively sealed space, effectively isolating external environmental interference such as humidity and dust, which is particularly suitable for plastic raw materials such as PET granules and masterbatches that are easily affected by the environment. Compared with traditional open storage or simple cover structures, this solution significantly improves the stability of raw material storage through active sealing design, reduces problems such as raw material oxidation, clumping, and color crosstalk caused by environmental factors, and ensures the consistency of product quality in subsequent blow molding. The data terminal 6, sensors 52, and control unit 51 form a closed-loop control system, reducing raw material loss and the frequency of manual intervention through sealed storage and precise monitoring.

[0045] like Figure 4 , Figure 7 As shown, the palletizing robot 2 is equipped with a scanner 7, and each storage box 4 has a vertically fixed mounting plate 8. A QR code 81 or barcode is affixed to the mounting plate 8. The scanner 7 communicates with the data terminal 6. When the scanner 7 on the palletizing robot 2 moves within the picking channel 3, it can scan the QR code 81 on the mounting plate 8 of the storage box 4 in real time, achieving precise positioning of "one code per box". The data terminal 6, by comparing the scan results with preset inventory information, can quickly verify the type (such as PET granules, masterbatch), batch, and storage status of the raw materials in the storage box 4, preventing accidental picking or mixing of materials by the robot. This is particularly suitable for scenarios with strict control over multiple colors and formulations of raw materials in plastic bottle production.

[0046] like Figures 3-7As shown, the control unit 51 includes two symmetrically arranged control components 53 and a movable plate 54. The two control components 53 are symmetrically arranged on opposite inner walls of the storage box 4, and each control component 53 includes a straight rail 530, a flat plate 531, a fixed plate 532, a lifting plate 533, and two hinged plates 534. The straight rail 530 is fixed to the inner wall of the storage box 4 along its length. The two ends of the movable plate 54 are movably inserted into the two straight rails 530, and a notch 541 is formed on one side wall of the movable plate 54. The bottom end of the fixed plate 532 is fixedly connected to the movable plate 54, and the top end of the lifting plate 533 is fixedly connected to one end of a horizontally arranged sealing cover 5. The two hinged plates 534 are arranged in parallel along the height direction of the storage box 4, and the two ends of each hinged plate 534 are hinged to the fixed plate 532 and the lifting plate 533, respectively. A flat plate 531 is fixed to the inner wall of the storage box 4, and a Z-shaped groove 5310 is provided on the flat plate 531. The flat plate 531 is located directly above the straight rail 530. A guide post 535 is fixed on the upper hinge plate 534. The end of the guide post 535 away from the hinge plate 534 is movable and inserted into the Z-shaped groove 5310, and the guide post 535 is located in the upper middle part of the upper hinge plate 534. A notch 41 is provided in the bottom wall of the storage box 4, and the notch 41 communicates with the opening 40. The sealing cover 5 is a rectangular plate, and a receiving groove 501 is provided in the bottom wall of the rectangular plate. A flexible plate 502 is filled in the receiving groove 501, and the flexible plate 502 can cover the turnover box 10. The design of the flexible plate 502 increases the sealing performance of the sealing cover 5.

[0047] An L-shaped plate 55 is fixed to the top wall of the movable plate 54. The end of the L-shaped plate 55 away from the movable plate 54 is located directly above the notch 541, and insertion spaces 56 are formed on both sides of the L-shaped plate 55. The insertion spaces 56, the notch 541, and the gap 41 are connected sequentially from top to bottom. A lifting plate 21 for lifting the turnover box 10 is fixed on the palletizing robot 2. A pulling plate 22 is fixed on the lifting plate 21, and the pulling plate 22 can pass through the gap 41, the notch 541, and the insertion space 56 in sequence. The bottom wall of the movable plate 54 is fixedly connected to the mounting plate 8. The scanning gun 7 is mounted on the lifting plate 21.

[0048] Initially, the moving plate 54 is positioned at the opening of the storage box 4, and the guide post 535 is located at the horizontal starting section of the Z-shaped groove 5310 of the flat plate 531 (i.e., near the opening end of the storage box 4). At this time, the lifting plate 533 is at its highest point, and the sealing cover 5 is located at a high position inside the storage box 4, making room for the storage box 10. The palletizing robot 2 transports the storage box 10 to the opening of the storage box 4, precisely positioning it above the notch 541 of the moving plate 54, ensuring that the storage box 10 abuts against one end of the L-shaped plate 55. The palletizing robot 2 continues to push the storage box 10 into the storage box 4. The bottom of the storage box 10 generates friction with the moving plate 54, causing the moving plate 54 to move horizontally into the storage box 4 along the straight rails 530 on both sides. The two ends of the moving plate 54 are guided by the straight rails 530, maintaining horizontal linear movement and avoiding deviation. When the movable plate 54 moves horizontally, the fixed plate 532 at its bottom moves synchronously with it. The fixed plate 532 forms a four-bar linkage with the lifting plate 533 through two hinged plates 534. At this time, the guide post 535 of the upper hinged plate 534 begins to disengage from the horizontal starting section of the Z-shaped groove 5310 and enters the inclined groove section. The guide post 535 moves along the inclined section of the Z-shaped groove 5310 and descends with the lifting plate 533. The guide post 535 slides downwards along the inclined section of the Z-shaped groove 5310, forcing the upper hinged plate 534 to rotate around its hinge point with the fixed plate 532 and the lifting plate 533. The lifting plate 533 begins to descend vertically. At this time, the sealing cover 5 moves downwards synchronously with the lifting plate 533, gradually approaching the top opening of the turnover box 10. When the guide post 535 slides to the end of the inclined section of the Z-shaped groove 5310 and enters the horizontal termination section, the lifting plate 533 descends to its lowest point. At this moment, the sealing cover 5 completely covers the top opening of the turnover box 10, forming a sealed space. Through this structure, the control unit 51, with its four hinged rods and Z-shaped groove 5310, automatically and reliably converts the horizontal pushing motion of the turnover box 10 into the vertical lowering sealing motion of the sealing cover 5, without the need for an additional independent drive source. The structure is compact and the operation is smooth.

[0049] The scanner 7 on the lifting plate 21 of the palletizing robot first aligns with the mounting plate 8 fixed on the target storage box 4 and scans the QR code 81 on it. The scanned data is transmitted in real time to the data terminal 6 for secondary verification to confirm that the raw material information in the current storage box 4 is consistent with the instruction requirements. After verification, the palletizing robot proceeds to the next step. The robot controls its lifting plate 21 to rise, so that the pull plate 22 fixed on the lifting plate 21 is precisely aligned with the notch 41 on the bottom wall of the storage box 4. The pull plate 22 passes through the notch 41 and the gap in sequence, and finally enters the insertion space 56 formed by the L-shaped plate 55 and the top wall of the moving plate 54. The lifting plate 21 of the palletizing robot begins to move backward. Since the pull plate 22 is already inserted in the insertion space 56, the pulling force of the lifting plate 21 moving backward is transmitted to the moving plate 54 through the pull plate 22. Under the action of the pulling force, the moving plate 54 moves horizontally from the inside of the storage box 4 towards the opening along the straight rails 530 on both sides. The translation of the moving plate 54 is achieved through a four-bar linkage consisting of a fixed plate 532, a hinged plate 534, and a lifting plate 533. This linkage drives the guide column 535 to slide back from the horizontal termination section, through the inclined section, to the horizontal starting section within the Z-shaped groove 5310 of the flat plate 531. The lifting plate 533 is then lifted, and the sealing cover 5, fixed to it, rises smoothly, detaching from the top of the turnover box 10 and opening its top for removal. The turnover box 10, carried by the moving plate 54, is also pulled towards the opening of the storage box 4 along with the moving plate 54. When the moving plate 54 is fully pulled back to its initial position, the sealing cover 5 rises to its highest point, and the turnover box 10 is completely brought out to a position for easy grabbing. The palletizing robot controls its lifting plate 21 to descend, ensuring the bottom of the turnover box 10 rests completely on the lifting plate 21, thus providing support. Palletizing robot 2, carrying the retrieved tote 10, departs from the picking channel 3 and heads to the next destination (such as the production line supply point) to complete the picking task. The lifting and lowering of the sealing lid relies on the movement of the tote, consuming no additional electricity or compressed air, thus reducing costs. Especially in large-scale warehousing scenarios, long-term operation can significantly reduce overall energy consumption and lower enterprise operating costs.

[0050] Second embodiment:

[0051] like Figure 5 , Figure 6Each storage box 4 is also equipped with a clamping unit 9, which includes a lead screw 91, a guide rod 92, and two clamping arms 93. The lead screw 91 and guide rod 92 are both arranged along the width direction of the storage box 4, and both are fitted with clamping arms 93. The top ends of the two clamping arms 93 are slidably mounted on the guide rod 92. Both clamping arms 93 are located on the storage box 4, between the opening and the control unit 51. The two ends of the lead screw 91 are a left rotating section 910 and a right rotating section 911, respectively. The top ends of the two clamping arms 93 are screwed onto the left rotating section 910 and the right rotating section 911, respectively. The lead screw 91 is mounted on the opposite side walls of the storage box 4, and one end of the lead screw 91 extends out of the storage box 4 and connects to a drive mechanism 94 for rotating it. The two ends of the guide rod 92 are fixed to the opposite side walls of the storage box 4. The drive mechanism 94 includes a drive pulley 946, a rack 942, and a belt 943. The rack 942 is fixed to the top wall of the movable plate 54 along the length of the storage box 4. A rotating shaft 944 is rotatably mounted on one side wall of the storage box 4. One end of the rotating shaft 944 is fixedly fitted with a spur gear 945, which meshes with the rack 942. The other end of the rotating shaft 944 passes through the storage box and is fixedly fitted with a drive pulley 946. One end of the lead screw 91 is coaxially connected to the connecting shaft 947. The connecting shaft 947 is fixedly fitted with a driven pulley 948. A belt 943 is fitted on the drive pulley 946 and the driven pulley 948.

[0052] The workflow of this embodiment is as follows: The palletizing robot 2 pushes the turnover box 10 into the storage box 4. The turnover box 10 moves against the L-shaped plate 55, thereby driving the moving plate 54 to move along the straight rail 530 into the storage box 4. As the moving plate 54 moves inward, the rack 942 fixed on its top wall also moves synchronously. The rack 942 meshes with the spur gear 945, driving the spur gear 945 to rotate. The rotation of the spur gear 945 is transmitted to the drive pulley 946 at the other end through the rotating shaft 944. The drive pulley 946 transmits the rotational motion to the driven pulley 948 through the belt 943, thereby driving the connecting shaft 947 and the lead screw 91 to rotate together. The lead screw 91 is designed with threaded sections with opposite directions of rotation at both ends (i.e., left rotating section 910 and right rotating section 911). The tops of the two clamping arms 93 are screwed onto the two threads, and their tops simultaneously slide onto the guide rod 92. The guide rod 92 ensures that the clamping arms 93 can only move in a straight line and will not rotate with the lead screw 91. When the lead screw 91 rotates, because the threads at both ends rotate in opposite directions, the two clamping arms 93 screwed onto it will move towards the center along the guide rod 92 simultaneously. At this stage, the rotation direction of the lead screw 91 is designed to drive the two clamping arms 93 to retract towards the center. At this time, the turnover box 10 is being pushed in, and the two clamping arms 93 just approach from both sides synchronously, firmly clamping the upper middle part of the turnover box 10 or the preset clamping part. When the moving plate 54 reaches the innermost position and the sealing cover 5 is completely closed, the clamping arms 93 also just reach the end of their clamping stroke, accurately fixing the turnover box 10 at the center position of the width of the storage box 4, and the two clamping arms clamp the turnover box, thereby achieving the purpose of fixing the turnover box.

[0053] When the palletizing robot 2 needs to retrieve goods, its pull plate 22 hooks onto the moving plate 54 and pulls it outward. The moving plate 54 moves outward in the reverse direction, causing the rack 942 to move in the opposite direction, which in turn drives the spur gear 945, shaft 944, drive pulley 946, belt 943, driven pulley 948, and lead screw 91 to all rotate in the opposite direction. Simultaneously, the gripping arm 93 releases. When the moving plate 54 is fully reset, the gripping arm 93 also fully opens to its maximum position, making room for the removal of the turnover box 10 without any interference. Since the gripping action relies entirely on the kinetic energy of the moving plate 54, it does not consume additional electrical energy or compressed air, reducing costs. Especially in large-scale warehousing scenarios, long-term operation can significantly reduce overall energy consumption and lower enterprise operating costs. The stable gripping of the upper part or a preset position of the turnover box 10 by the gripping arm 93 can counteract multiple interference factors, including slight vibrations in the warehouse environment (such as the passage of other robots or equipment operation) and slight pressure when the sealing cover 5 descends. If these disturbances cause the turnover box 10 to shift, gaps may appear between the sealing cover 5 and the top opening of the turnover box 10, leading to the intrusion of external moisture and dust (especially for raw materials such as PET granules and masterbatches that are susceptible to environmental influences). Clamping and fixing ensure that the box body is always precisely aligned with the sealing cover 5, completely eliminating the risk of seal failure and ensuring the stability of raw material storage.

[0054] Other embodiments:

[0055] Each sensor 52 is fixedly mounted via a support rod perpendicular to the sealing cover 5, with its detection end located at the end of the support rod. In each storage box 4, an infrared generator is installed at the end of any one of the support rods, and this infrared generator establishes a communication connection with the data terminal 6.

[0056] When the sealing cover 5 descends, allowing the infrared generator to enter the turnover box 10, its emitted infrared beam is blocked by the wall of the turnover box 10 or the raw materials. This blocking is detected by the infrared generator, which immediately sends a trigger signal to the data terminal 6. Upon receiving this signal, the data terminal 6 determines that the sensor group 52 has correctly arrived at its working position and then sends instructions to all sensors 52 in the storage box 4 to start their detection work.

[0057] Furthermore, all sensors 52 move in a straight downward trajectory under the influence of the sealing cover 5. This unique movement allows the sensors 52 to traverse different spatial levels within the turnover box 10 during their descent, thereby enabling effective detection of parameters at multiple different locations within the box and improving the comprehensiveness and representativeness of the measurements.

[0058] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
