Description

Technical Field

[0001] The present invention relates to the technical field of stereoscopic warehouses, and in particular to an automated stereoscopic warehouse for storage. Background Art

[0002] In the plastic bottle production industry, the storage quality and management efficiency of raw materials (such as PET pellets and masterbatches) directly impact production continuity and product quality. Currently, the industry primarily utilizes automated high-bay warehouses (HVWs) to achieve large-scale storage of various types of raw materials. These warehouses utilize a matrix of racks to arrange storage space, and employ palletizing robots to transfer raw materials within designated aisles, improving space utilization and operational automation. Existing HVWs often focus on physical handling and location management, lacking real-time monitoring capabilities for raw material conditions (such as humidity, temperature, and inventory levels). These systems still require manual unpacking inspections or rely on fixed environmental sensors, preventing effective internal monitoring of the raw materials. For example, paragraph 0105 of Patent Publication No. CN222947438U, a Chinese utility model patent for a HVW warehouse, discloses that each storage cavity can be equipped with a temperature sensor that measures the current temperature within the cavity and transmits the results to a controller. Although it is mentioned that a temperature sensor is installed in the shelf cavity, the detection object is the cavity environment rather than the raw materials themselves. Similarly, another patent announcement number: CN215930253U - China Utility Model Patent A three-dimensional warehouse with temperature and humidity control function, the patent discloses that "a sensor group for monitoring humidity and temperature is provided inside 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 warehouse body respectively." It describes that a temperature and humidity sensor group is installed in each layer of storage column, which still belongs to the spatial level monitoring and cannot be embedded in the raw materials for in-situ measurement, so it is difficult to truly reflect the actual state of the materials. In addition, existing three-dimensional warehouses also have certain limitations in terms of sealing. Especially when storing plastic raw materials that are easily affected by the environment, a simple cover structure is difficult to effectively prevent moisture and dust, affecting the stability of the raw materials. Summary of the Invention

[0003] The main purpose of the present invention is to provide an automated storage warehouse to solve the problem that existing automated warehouses often focus on physical transportation and location management, lack the ability to monitor the real-time status of raw materials, still require manual intervention for unpacking inspection or rely on fixed environmental sensors, and cannot achieve independent and accurate monitoring of the internal conditions of each raw material turnover box.

[0004] In order to achieve the above-mentioned object, the present invention provides an automated three-dimensional warehouse for storage, comprising two symmetrically arranged warehouse racks, with a picking passage reserved between the two warehouse racks for a palletizing robot to walk through; Each warehouse rack is equipped with a matrix of rectangular storage boxes. One side of the storage box is open to the access channel. A sealing cover is provided inside the storage box for covering the turnover box. The sealing cover is connected to a control unit for driving the movement and lifting of the storage box. Among them, multiple sensors are set on the sealing cover, and the multiple sensors can be inserted into the turnover box by lifting the sealing cover, and all of them communicate with the data terminal.

[0006] A preferred solution is that the sensor is a fill level sensor, a humidity sensor, or a temperature sensor.

[0007] A preferred solution is to set a scanner on the palletizing robot, and vertically fix a mounting plate on each storage box, on which a QR code or bar code is affixed, so that the scanner communicates with the data terminal.

[0008] A preferred solution is that the control unit includes two symmetrically arranged control members and a moving plate; The two control members are symmetrically arranged on opposite inner side walls of the storage box and include a straight rail, a flat plate, a fixed plate, a lifting plate and two hinged plates; The straight rails are fixed on the inner side wall of the storage box along the length direction thereof, the two ends of the movable plate are movably inserted on the two straight rails, and a notch is provided on one side wall; The bottom end of the fixed plate is fixedly connected to the movable plate, and the top end of the lifting plate is fixedly connected to one end of the horizontally arranged sealing cover; Two hinged plates are arranged in parallel along the height direction of the storage box, and both ends of each hinged plate are hinged to the fixed plate and the lifting plate respectively; The flat plate is fixed on the inner wall of the storage box and is provided with a Z-shaped groove. The flat plate is located directly above the straight rail. A guide post is fixed on the upper hinge plate, and the guide post is movable and inserted into the Z-shaped groove at one end away from the hinge plate, and is located in the upper middle part of the upper hinge plate; The bottom wall of the storage box is provided with a notch which is communicated with the opening.

[0009] A preferred solution is that an L-shaped plate is fixed on the top wall of the movable plate, the end of the L-shaped plate away from the movable plate is located directly above the notch, and insertion spaces are formed on both sides, and the insertion space, the notch and the gap are connected in sequence from top to bottom; A lifting plate for lifting turnover boxes is fixed on the palletizing robot, and a pulling plate is fixed on the lifting plate. The pulling plate can pass through the notch, the gap and the insertion space in sequence; The bottom wall of the movable plate is fixedly connected to the mounting plate; The scanner is installed on the lifting plate.

[0010] A preferred solution is that the sealing cover is a rectangular plate body, the bottom wall of the rectangular plate body is provided with a receiving groove, the receiving groove is filled with a flexible plate, and the flexible plate can be covered on the turnover box.

[0011] A preferred solution is that each storage box is further provided with a clamping unit, the clamping unit comprising a lead screw, a guide rod and two clamping arms; The lead screw and the guide rod are arranged along the width direction of the storage box, and the two clamping arms are sleeved. The top ends of the two clamping arms are slidably arranged on the guide rod. The two clamping arms are both located on the storage box and between the opening and the control unit.

[0012] The two ends of the screw are respectively a left-rotating section and a right-rotating section, and the top ends of the two clamping arms are respectively threaded and sleeved on the left-rotating section and the right-rotating section.

[0014] The beneficial effects of the above scheme are: The sealing lid integrates multiple sensors (such as humidity, temperature, and material level sensors). As the lid is moved by the lifting control unit, these sensors are dynamically inserted into the turnover box, enabling real-time parameter collection for each individual raw material unit. A data terminal receives and processes sensor data in real time, establishing a "one-box, one-file" digital monitoring system. This completely solves the monitoring lag and data fragmentation issues inherent in traditional warehouses, which rely on manual spot checks or fixed sensors. The sealing lid forms a relatively sealed space with the storage box, effectively isolating it from external environmental interference such as moisture and dust. This solution is particularly suitable for environmentally sensitive plastic materials such as PET pellets and masterbatches. Compared to traditional open storage or simple lid structures, this solution's active sealing design significantly improves raw material storage stability, reducing environmental issues such as oxidation, agglomeration, and color crosstalk, thereby ensuring consistent quality in subsequent blow-molded products. The data terminal, sensors, and control unit form a closed-loop control system. Through sealed storage and precise monitoring, this solution minimizes raw material loss and reduces the need for manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] First embodiment: like Figures 1-8As shown, this embodiment provides an automated three-dimensional warehouse for storage, including two symmetrically arranged warehouse racks 1, with a pick-up passage 3 reserved between the two warehouse racks 1 for a palletizing robot 2 to move through. A plurality of rectangular storage boxes 4 are fixed in a matrix on each warehouse rack 1. One side of the storage box 4 has an opening 40 facing the pick-up passage 3. A sealing cover 5 for covering the turnover box 10 is provided inside the storage box 4. The sealing cover 5 is connected to a control unit 51 for driving the turnover box 10 to move and rise. Among them, 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), as shown in FIG. Figure 7 As shown, the sealing cover 5 is provided with multiple sensors 52, which are material level sensors, humidity sensors, or temperature sensors. The multiple sensors 52 can be inserted into the turnover box 10 by raising and lowering the sealing cover 5, and the multiple sensors 52 communicate with the data terminal 6. The data terminal 6 is a PC computer.

[0020] The sealing lid 5 integrates multiple sensors 52 (such as humidity, temperature, and material level sensors). When the lifting control unit 51 drives the sealing lid 5, the sensors 52 are dynamically inserted into the turnover box 10, enabling real-time parameter collection for each individual raw material unit. The data terminal 6 receives and processes the sensor 52 data in real time, establishing a "one-box, one-file" digital monitoring system. This completely solves the monitoring lag and data dispersion issues associated with traditional warehouses that rely on manual sampling or fixed sensors 52. The sealing lid 5 forms a relatively sealed space with the storage box 4, effectively isolating it from external environmental interference such as moisture and dust. This solution is particularly suitable for environmentally sensitive plastic raw materials such as PET pellets and masterbatches. Compared to traditional open storage or simple lid structures, this solution significantly improves raw material storage stability through an active sealing design, reducing environmental issues such as raw material oxidation, agglomeration, and color crosstalk, thereby ensuring consistent quality in subsequent blow-molded products. The data terminal 6, sensors 52, and control unit 51 form a closed-loop control system. Through sealed storage and precise monitoring, raw material loss is minimized and the need for manual intervention is reduced.

[0021] like Figure 4 、 Figure 7 As shown, the palletizing robot 2 is equipped with a scanner 7. Each storage bin 4 is vertically secured with a mounting plate 8, which is affixed with a QR code 81 or barcode. The scanner 7 communicates with a data terminal 6. As the palletizing robot 2 moves within the pickup channel 3, the scanner 7 scans the QR code 81 on the mounting plate 8 of the storage bin 4 in real time, achieving precise "one bin, one code" location. By comparing the scan results with pre-set inventory information, the data terminal 6 can quickly verify the type (e.g., PET pellets, masterbatch), batch, and storage status of the raw materials in the storage bin 4, preventing the robot from misplacing or mixing materials. This is particularly applicable to the strict control of multi-color, multi-formulation raw materials in plastic bottle production.

[0022] like Figure 3-Figure 7As shown, the control unit 51 includes two symmetrically arranged control members 53 and a movable plate 54. The two control members 53 are symmetrically arranged on the opposite inner walls of the storage box 4, and each control member 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 the length direction, and the two ends of the movable plate 54 are movably inserted on the two straight rails 530, and a notch 541 is provided 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 the horizontally arranged sealing cover 5. The two parallel hinged plates 534 are arranged 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. The flat plate 531 is fixed on the inner wall of the storage box 4, and the flat plate 531 is provided with a Z-shaped groove 5310. 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. The bottom wall of the storage box 4 is provided with a notch 41, and the notch 41 is connected to the opening 40. The sealing cover 5 is a rectangular plate body, and the bottom wall of the rectangular plate body is provided with a receiving groove 501. The receiving groove 501 is filled with a flexible plate 502, and the flexible plate 502 can be covered on the turnover box 10. The design of the flexible plate 502 increases the sealing performance of the sealing cover 5.

[0023] An L-shaped plate 55 is fixed to the top wall of the movable plate 54. The end of the L-shaped plate 55 facing away from the movable plate 54 is located directly above the notch 541. Insertion spaces 56 are formed on both sides of the L-shaped plate 55. Insertion spaces 56, notch 541, and cutout 41 are sequentially connected from top to bottom. A lifting plate 21 for lifting the turnover box 10 is fixed to the palletizing robot 2. A pulling plate 22 is fixed to the lifting plate 21. The pulling plate 22 can pass through the cutout 41, notch 541, and insertion space 56 in sequence. The bottom wall of the movable plate 54 is fixedly connected to the mounting plate 8. The scanner 7 is mounted on the lifting plate 21.

[0024] In the initial state, the movable plate 54 is located at the opening of the storage box 4, and the guide column 535 is at the horizontal starting section of the Z-shaped groove 5310 of the flat plate 531 (i.e., close to the open end of the storage box 4). At this time, the lifting plate 533 is at the highest point, and the sealing cover 5 is located high inside the storage box 4, making room for the turnover box 10 to be stored. The palletizing robot 2 moves the turnover box 10 to the opening of the storage box 4, and accurately positions it above the notch 541 of the movable plate 54, ensuring that the turnover box 10 is in contact with one end of the L-shaped plate 55. The palletizing robot 2 continues to push the turnover box 10 into the inside of the storage box 4, and the bottom of the turnover box 10 generates friction with the movable plate 54, driving the movable plate 54 to move horizontally along the straight rails 530 on both sides toward the inside of the storage box 4. The two ends of the movable plate 54 are guided by the straight rails 530 to maintain horizontal linear motion and avoid deviation. As the movable plate 54 translates, the fixed plate 532, attached to its bottom end, translates synchronously with it. The fixed plate 532, connected to the lifting plate 533 via two hinged plates 534, forms a four-bar linkage. At this point, the guide post 535 of the upper hinged plate 534 begins to disengage from the horizontal starting section of the Z-groove 5310 and enter the inclined section. The guide post 535 moves along the inclined section of the Z-groove 5310, descending with the lifting plate 533. The guide post 535 slides diagonally downward within the inclined section of the Z-groove 5310, forcing the upper hinged plate 534 to rotate about its hinge point with the fixed plate 532 and the lifting plate 533. The lifting plate 533 begins to descend vertically. At this point, the sealing cover 5 moves downward 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-groove 5310 and enters the horizontal terminal section, the lifting plate 533 reaches its lowest point. At this point, the sealing cover 5 completely covers the top of the turnover box 10, forming a sealed space. This structural control unit 51, through the ingenious combination of four hinged rods and the Z-shaped groove 5310, automatically and reliably converts the horizontal advancement of the turnover box 10 into the vertical downward sealing action of the sealing cover 5. This eliminates the need for an additional independent drive source, resulting in a compact structure and smooth operation.

[0025] The scanner 7 on the palletizing robot's lifting platform 21 first aligns with the mounting plate 8 fixed to the target storage box 4 and scans the QR code 81 thereon. The scanned data is transmitted in real time to the data terminal 6 for secondary verification to confirm that the raw material information currently in the storage box 4 is consistent with the instructions. Once verified, the palletizing robot proceeds to the next step. The robot controls the lifting platform 21 to rise, precisely aligning the pull plate 22 fixed to the lifting platform 21 with the notch 41 in the bottom wall of the storage box 4. The pull plate 22 passes through the notch 41 and the notch, ultimately entering the insertion space 56 formed by the L-shaped plate 55 and the top wall of the movable plate 54. The palletizing robot's lifting platform 21 begins to move backward. Since the pull plate 22 is already inserted in the insertion space 56, the pulling force of the palletizing robot's lifting platform 21 is transmitted through the pull plate 22 to the movable plate 54. Under the action of the pulling force, the movable plate 54 moves horizontally along the straight rails 530 on both sides, from the interior of the storage box 4 toward the open door. The translation of the movable plate 54, through a four-bar linkage consisting of a fixed plate 532, a hinged plate 534, and a lifting plate 533, drives the guide column 535 to slide from the horizontal end section through the inclined section back to the horizontal starting section within the Z-shaped groove 5310 of the flat plate 531. As the lifting plate 533 is lifted, the sealing cover 5 fixed to it rises steadily, disengaging from the top of the turnover box 10 and opening the top of the turnover box 10 in preparation for removal. The turnover box 10 carried by the movable plate 54 is also pulled toward the opening of the storage box 4 along with the movable plate 54. When the movable 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 that is convenient for grasping. The stacking robot controls its lifting plate 21 to descend, so that the bottom of the turnover box 10 completely falls on the lifting plate 21, thereby achieving support. Palletizing robot 2, carrying the removed turnover box 10, exits pickup channel 3 and heads for the next destination (e.g., a production line feed point), completing its pickup mission. The lifting and lowering of the sealing lid relies on the movement of the turnover box, consuming no additional electricity or compressed air and reducing costs. Especially in large-scale warehousing scenarios, long-term operation can significantly reduce overall energy consumption and lower operating costs.

[0026] Second embodiment: like Figure 5 、 Figure 6Each storage box 4 is also equipped with a clamping unit 9, which comprises a lead screw 91, a guide rod 92, and two clamping arms 93. The lead screw 91 and guide rod 92 are arranged along the width of the storage box 4, and are fitted with clamping arms 93. The top ends of the two clamping arms 93 slide over the guide rod 92. Both clamping arms 93 are located on the storage box 4, between the opening and the control unit 51. The lead screw 91 has a left-rotating section 910 and a right-rotating section 911 at either end, respectively. The top ends of the two clamping arms 93 are threadedly sleeved onto the left-rotating section 910 and the right-rotating section 911, respectively. The lead screw 91 is pivotally mounted on opposite sides of the storage box 4, with one end extending through the storage box 4 to connect to a drive mechanism 94 that drives its rotation. The guide rods 92 are fixed to the opposite sides of the storage box 4. The drive mechanism 94 comprises a drive pulley 946, a rack 942, and a belt 943. The rack 942 is fixed on the top wall of the movable plate 54 along the length of the storage box 4, and a rotating shaft 944 is rotated on one side wall of the storage box 4. One end of the rotating shaft 944 is fixedly sleeved on a spur gear 945, and the spur gear 945 is engaged with the rack 942. The other end of the rotating shaft 944 passes through the storage box and is fixedly sleeved on a driving pulley 946. One end of the screw 91 is coaxially connected to a connecting shaft 947, and the connecting shaft 947 is fixedly sleeved on a driven pulley 948. A belt 943 is sleeved on the driving pulley 946 and the driven pulley 948.

[0027] The working process of this embodiment is as follows: the palletizing robot 2 pushes the turnover box 10 into the storage box 4, and the turnover box 10 moves against the L-shaped plate 55, thereby driving the movable plate 54 to move horizontally toward the inside of the storage box 4 along the straight rail 530. As the movable plate 54 moves inward, the rack 942 fixed on its top wall also moves synchronously. The rack 942 engages with the spur gear 945, driving the spur gear 945 to rotate. The rotation of the spur gear 945 is transmitted to the driving pulley 946 at the other end through the rotating shaft 944. The driving 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 to have threaded sections with opposite rotation directions at both ends (i.e., a left-rotating section 910 and a right-rotating section 911). The top ends of the two clamping arms 93 are screwed onto these two threads, and their top ends simultaneously slide over the guide rod 92. The guide rod 92 ensures that the clamping arms 93 can only move linearly and cannot rotate with the lead screw 91. When the lead screw 91 rotates, due to the opposite rotation of the threads at both ends, the two clamping arms 93 screwed onto it will move simultaneously toward the center along the guide rod 92. During this phase, the rotation direction of the lead screw 91 is designed to drive the two clamping arms 93 toward the center. At this time, as the turnover box 10 is being pushed in, the two clamping arms 93 coincidentally converge from both sides, firmly clamping the turnover box 10 at the upper middle portion or the predetermined clamping position. When the movable plate 54 reaches its innermost position and the sealing cover 5 is fully closed, the clamping arms 93 also reach the end of their clamping travel, precisely securing the turnover box 10 at the center of the width of the storage box 4. The two clamping arms clamp the turnover box, thereby achieving the purpose of securing the turnover box.

[0028] When palletizing robot 2 needs to retrieve a package, its pull plate 22 hooks onto the movable plate 54 and pulls it outward. The reverse motion of the components causes the movable plate 54 to move outward, driving the rack 942 in the opposite direction. This in turn drives the spur gear 945, rotating shaft 944, drive pulley 946, belt 943, driven pulley 948, and lead screw 91 all to rotate in the opposite direction. The clamping arm 93 simultaneously releases. When the movable plate 54 is fully restored, the clamping arm 93 also fully opens to its maximum position, clearing space for the turnover box 10 to be removed without any interference. Because the clamping action relies entirely on the kinetic energy of the movable plate 54, no additional electricity or compressed air is consumed, reducing costs. Especially in large-scale warehousing scenarios, long-term operation can significantly reduce overall energy consumption and lower operating costs. The clamping arm 93's stable grip on the upper middle portion or a predetermined location of the turnover box 10 offsets multiple interference factors, including minor vibrations in the warehouse environment (such as other robots passing by or equipment operating) and the slight pressure from the lowering of the sealing cover 5. If these interferences cause the turnover box 10 to shift, a gap between the sealing cover 5 and the top of the turnover box 10 could easily form, potentially allowing moisture and dust to enter (especially for environmentally sensitive raw materials such as PET pellets and masterbatches). Clamping ensures that the box body and the sealing cover 5 are always precisely aligned, completely eliminating the risk of seal failure and ensuring the stability of raw material storage.

[0029] Other embodiments: Each sensor 52 is fixedly mounted on 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 support rod, and the infrared generator establishes a communication connection with the data terminal 6.

[0030] When the sealing cover 5 descends, allowing the infrared generator to enter the interior of the turnover box 10, the infrared beam it emits is blocked by the wall of the turnover box 10 or the raw materials. This obstruction 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 reached the working position and immediately issues a command to all sensors 52 in the storage box 4 to initiate detection.

[0031] Furthermore, all sensors 52, driven by the sealing cover 5, move in a straight, oblique downward trajectory. This unique motion allows the sensors 52 to traverse different spatial levels within the turnover box 10 during their descent, effectively detecting parameters at multiple locations within the box and enhancing the comprehensiveness and representativeness of the measurements.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
