Description

Technical Field

[0001] This invention relates to aisle palletizing machine technology, specifically a peanut protein powder packaging and palletizing equipment for warehousing. Background Technology

[0002] As is widely known, aisle palletizers are commonly used automated equipment in intelligent warehouses. They are usually used in conjunction with multiple sets of shelves and floor rails. They connect the production and packaging workshops and the warehouse through conveyor belts, and can automatically receive and identify packaging boxes and accurately transport them to the corresponding shelf positions to complete storage. They are widely used in the warehousing and palletizing operations of various goods and are one of the core equipment for improving warehouse operation efficiency and realizing automated management.

[0003] Existing aisle palletizers have significant shortcomings: Firstly, they lack efficient layered support and linkage deployment structures, making it impossible to achieve automatic layered support and orderly storage of packaging boxes, requiring manual assistance or relying on complex control programs, resulting in low palletizing efficiency. Secondly, the spacing between the equipment and the shelves is insufficient, making goods prone to falling off and being damaged during transportation, and the space utilization of the support structure is low, making it difficult to adapt to high-density warehousing needs. At the same time, some equipment requires additional power to drive multiple functional components, resulting in complex structures, high energy consumption, and poor versatility and operational reliability. Summary of the Invention

[0004] The purpose of this invention is to provide a peanut protein powder packaging and palletizing device for warehousing, so as to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising: multiple sets of shelves, with a ground rail installed between the multiple sets of shelves, and an aisle palletizing machine composed of columns and lifting frames installed on the ground rail; further comprising: The partitions, in multiple sets, are rotatably mounted on the inner side of the lifting frame in a stacked manner. Telescopic plates, which are telescopically mounted at both ends of the partition; The limiting mechanism is connected to the partition plate. When the upper set of partition plates rotates from an inclined state to a horizontal state, the partition plate passively drives the limiting mechanism to pop the next set of partition plates out from the inner wall of the lifting frame. At the same time, the transmission mechanism pushes the telescopic plate out from inside the partition plate.

[0006] As a further description of the above technical solution: multiple sets of folding grooves are evenly spaced on the inner sidewalls at both ends of the lifting frame, and a U-shaped partition is rotatably connected in the folding groove.

[0007] As a further description of the above technical solution: a fixing rod is fixedly connected to both ends of the folding groove, and the fixing rod passes through the cam and is rotatably inserted into both ends of the partition.

[0008] As a further description of the above technical solution: the limiting mechanism includes cams fixedly installed at both ends of a fixed rod. The cams are circular and protrude outward on one side. A contact plate is slidably connected to the surface of the cam. The contact plate is movably inserted into the bottom of both ends of the folding groove. The bottom of the contact plate is connected to the inner wall of the lifting frame through a return spring. The bottom of the contact plate is fixedly connected to the top of a top rod. The bottom end of the top rod is inserted into the top of a lower set of folding grooves and connected to the contact plate. The top of the contact plate is connected to the inner wall of the top of the folding groove through a return spring. The surface of the contact plate slidably abuts against the surface of the partition plate.

[0009] As a further description of the above technical solution: the contact plate is configured with a right-angled trapezoidal cross-section, and the hypotenuse slides to contact the partition.

[0010] As a further description of the above technical solution: the transmission mechanism includes an active gear column that is rotatably connected to a fixed rod inserted into one end of the partition through a bearing. The end face of the active gear column is fixedly connected to the inner side wall of the partition. The active gear column is connected to a threaded drive shaft through a transmission chain. The threaded drive shaft is rotatably installed in the partition and threadedly connected to a threaded travel rod above it. The threaded travel rod is located at the bottom of the telescopic plate.

[0011] As a further description of the above technical solution: the thread between the threaded drive shaft and the threaded travel rod is inclined, so that the rotation of the threaded drive shaft drives the threaded travel rod to move the telescopic plate laterally.

[0012] As a further description of the above technical solution: there is a guide roller at the top of the partition.

[0013] As a further description of the above technical solution: conveyor belts are provided at the bottom of the lifting frame and on the surface of the partition.

[0014] As a further description of the above technical solution: a lifting platform is provided at the bottom center of the lifting frame.

[0015] In the above technical solution, the peanut protein powder packaging and palletizing equipment for warehousing provided by the present invention has the following beneficial effects: 1. Achieve automated layered palletizing: Through the linkage of the upper and lower stacked rotating design of the partitions and the limiting mechanism, the upper partition can automatically pop out the next set of partitions after carrying the packaging box. With the help of the lifting platform and conveyor belt, the packaging boxes can be automatically received and stored in layers without manual intervention, thus improving palletizing efficiency.

[0016] 2. Ensure conveying stability: The telescopic plates at both ends of the partition extend synchronously through the transmission mechanism to fill the gap between the lifting frame and the shelf, effectively preventing the packaging boxes from falling off during conveying; the guide rollers at the top of the partition can assist the packaging boxes in lifting and lowering smoothly, reducing collision damage.

[0017] 3. High space utilization: The partitions are initially tilted and folded, and turn to be horizontal when under load. The multi-layer design can make full use of the vertical space of the lifting frame, adapt to the high-density storage needs of intelligent warehouses, and increase storage capacity.

[0018] 4. Strong structural linkage: The limit mechanism and the transmission mechanism achieve synchronous action through mechanical linkage, which eliminates the need for additional power drive, simplifies the equipment structure, reduces energy consumption, and makes the operation more reliable.

[0019] 5. Wide adaptability: The equipment can accurately connect to any position of multiple sets of shelves through the movement and lifting of the ground rail and lifting frame, meeting the storage and palletizing needs of peanut protein powder packaging boxes of different specifications, and has strong versatility.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-12 This invention provides a technical solution for a peanut protein powder packaging and palletizing equipment for warehousing: It includes: multiple sets of shelves 1, with ground rails 2 installed between the multiple sets of shelves 1, and an aisle palletizing machine consisting of columns 3 and lifting frames 4 installed on the ground rails 2; it also includes: Partition 6, multiple sets of partition 6 are stacked and rotated inside the lifting frame 4; Telescopic plate 9, which is telescopically installed at both ends of partition plate 6; The limiting mechanism is connected to the partition 6 in a transmission manner. When the upper partition 6 rotates from an inclined state to a horizontal state, the partition 6 passively drives the limiting mechanism to pop the next partition 6 out from the inner wall of the lifting frame 4. At the same time, the transmission mechanism pushes the telescopic plate 9 out from inside the partition 6.

[0025] In another embodiment of the present invention, preferably, multiple sets of folding grooves 5 are evenly spaced on the inner sidewalls at both ends of the lifting frame 4, and a U-shaped partition 6 is rotatably connected in the folding groove 5.

[0026] In another embodiment of the present invention, a fixing rod 12 is fixedly connected to both ends of the folding groove 5. The fixing rod 12 passes through the cam 10 and is rotatably inserted into both ends of the partition plate 6.

[0027] After the peanut protein powder is produced and packaged in a fixed box, the box can be placed in an intelligent warehouse for storage. The most common method used in current intelligent warehouses is to set up multiple sets of shelves 1 and simultaneously set up automatic aisle palletizers. The aisle palletizers are connected to one end of the conveyor belt 7, and the other end of the conveyor belt 7 is connected to the production and packaging workshop. During operation, the aisle palletizer transports peanut protein powder packaging boxes to the warehouse entrance via conveyor belt 7. The palletizer then automatically identifies the packaging boxes and places them onto the corresponding shelves 1 for storage. The specific operation is as follows: When the conveyor belt 7 transports the packaging box to the sampling position of the aisle palletizer, the retractable conveyor belt 7 at the bottom of the lifting frame 4 on the aisle palletizer is inserted under the packaging box and then lifted. After the conveyor belt 7 returns to its original position, it can transport the packaging box to the surface of the lifting frame 4. At this time, the lifting platform 8 at the bottom of the lifting frame 4 lifts upward, lifting the first group of packaging boxes to the top of the lifting frame 4. After the packaging boxes are squeezed and separated from the partitions 6 on both sides, the lifting platform 8 lowers. At this time, the bottom sides of the packaging boxes squeeze downward to the top partition 6, thereby removing the partition 6 from the attached... Figure 12 The S1 state (initial state) is transformed into the S2 state (the state where goods are placed on top). At this time, the bottom sides of the packaging box are blocked by two sets of partitions 6 and stop at the top of the lifting frame 4. At this time, the conveyor belt 7 set in the lifting frame 4 can take a new packaging box from the end of the conveyor belt 7 connected to the production workshop, and use the lifting platform 8 to lift the packaging box and place it on the surface of the second set of partitions 6. The lifting frame 4 repeats the above actions until all the partitions 6 on the lifting frame 4 are filled with packaging boxes, or the required packaging box has been taken. Then the aisle palletizer can start to transport each set of packaging boxes to the corresponding position on the shelf 1. The column 3 and the lifting frame 4 form the mobile body of the aisle palletizer and move the mobile body on the ground rail 2. The lifting frame 4 can be raised and lowered on the column 3 to facilitate moving the lifting frame 4 to any position on the shelf 1. When the lifting frame 4 moves to the corresponding position of the shelf 1, the conveyor belt 7 on the surface of the corresponding partition 6 to be placed is started, and the packaging box on the surface of the partition 6 is transported to the shelf 1 with the guidance of the partition 6 and the telescopic plate 9. The following points need to be explained regarding the entire working process of the aforementioned lane palletizing machine: The foldable partitions 6 at both ends of the lifting frame 4 can only be unfolded from top to bottom to place packaging boxes. The partitions ensure that when placing packaging boxes from the lifting frame 4 onto the shelf 1, they can be arranged from bottom to top, or not in this order, without affecting the use of the partitions 6. The specific structure and description are as follows: In another embodiment of the present invention, the limiting mechanism includes a cam 10 fixedly installed at both ends of the fixed rod 12. The cam 10 is circular and protrudes outward on one side. The surface of the cam 10 slides against a contact plate 22. The contact plate 22 is movably inserted into the bottom of both ends of the folding groove 5. The bottom of the contact plate 22 is connected to the inner wall of the lifting frame 4 through a return spring 21. The bottom of the contact plate 22 is fixedly connected to the top of the top rod 19. The bottom end of the top rod 19 is inserted into the top of the lower set of folding grooves 5 and connected to the contact plate 22. The top of the contact plate 22 is connected to the inner wall of the top of the folding groove 5 through a return spring 21. The surface of the contact plate 22 slides against the surface of the partition plate 6.

[0028] In another embodiment of the present invention, the contact plate 22 is configured with a right-angled trapezoidal cross-section, and the hypotenuse slides to abut the partition plate 6.

[0029] The partitions 6 at both ends of the lifting frame 4 are arranged in an alternating vertical manner, combined with the attached... Figure 12 In state S1, the side partition 6 inside the lifting frame 4 is in a state where no packaging boxes are placed, while state S2 is in a state where packaging boxes are placed on the surface of the top partition 6, based on the above description. During the process of the lifting platform 8 lifting the packaging box upward, the two sides of the packaging box will first contact the guide roller 11 set at the top of the uppermost partition 6. Through the guidance of the rotatable guide roller 11, the packaging box is lifted upward and separated from the guide roller 11 and the partition 6. At this time, the height of the bottom of the packaging box is higher than the highest point of the uppermost partition 6. At this time, the lifting platform 8 descends, and the bottom of the packaging box will first contact the highest point of the partition 6, causing the partition 6 to flip downward, changing from the inclined state in state S1 to the horizontal state in state S2. At this time, the packaging box is placed on the surface of the two sets of partitions 6 at the top of the lifting frame 4 for storage. During the process of the aforementioned partition 6 changing from an inclined state to a horizontal state, the lower partition 6 automatically unfolds at a small angle, specifically as follows: The upper partition 6 unfolds under the weight of the packaging box. At this time, the U-shaped partition 6 is fixedly connected to both ends of the cam 10, and the end face of the cam 10 is rotatably connected to the fixing rod 12 through the torsion spring shaft. The fixing rod 12 is fixedly connected to the inner side wall of the folding groove 5. The other end of the fixing rod 12 is rotatably inserted into the partition 6 and connected to the active gear column 13 through the bearing. The active gear is connected to the threaded drive shaft 17 through the transmission chain 16. The threaded drive shaft 17 is rotatably set in the partition 6, and the threaded travel rod 18 is threadedly connected to the top of the threaded drive shaft 17. The threaded travel rod 18 is fixedly set in the bottom of the telescopic plate 9 and protrudes outward. The specific transmission method consists of two steps. The first step is as follows: When the partition 6 rotates counterclockwise during its unfolding process, it drives the cams 10 fixed at both ends to rotate accordingly. Due to its own size, the cams 10 press down on the abutment blocks 20 set at the bottom of both ends of the folding groove 5. After being pressed, the abutment blocks 20 stretch the return spring 21 downwards and drive the abutment plates 22, which are inserted at both ends of the top of the next set of folding grooves 5, to be inserted into the next set of folding grooves 5. At this time, the abutment plates 22, which are in the shape of right-angled trapezoids, abut against the top of the folded partition 6 in the next set of folding grooves 5, causing the lower partition 6 to pop out from the folding groove 5 and form an attachment. Figure 12 In the initial state of the uppermost partition 6 in the middle S1 state, after the next set of packaging boxes is pushed up and put down, the packaging boxes can be stored on the surface of the next set of partition 6 using the next set of partition 6. The second step is as follows: When the partition 6 rotates, it drives the active gear 13, which is fixedly connected to it and rotates through the bearing and the fixed rod 12, to rotate as well. The rotation of the active gear 13 will drive the rotation of the threaded drive shaft 17 through the transmission gear chain 16. The rotation of the threaded drive shaft 17 will drive the threaded travel rod 18 connected above to extend the telescopic plate 9 from inside the partition 6 to the outside. Thus, when it is necessary to push the packaging box on the surface of the partition 6 to the shelf 1, the telescopic plate 9 will provide a certain protection against the excessive gap between the lifting frame 4 and the shelf 1, and prevent the packaging box from falling off during the process of being conveyed from the lifting frame 4 to the shelf 1. After all the packaging boxes on the surface of the inner partition 6 of the lifting frame 4 are transported to the shelf 1, the partition 6 is reset due to the rotation of its own torsion spring shaft. It should be noted that since the initial state of the partition 6 is tilted outward, and the final state of the partition 6 after rotation is a horizontal state, the rotation angle of the partition 6 is less than 90 degrees.

[0030] In another embodiment of the present invention, the transmission mechanism includes an active gear 13 that is rotatably connected to a fixed rod 12 inserted into one end of the partition 6 via a bearing. The end face of the active gear 13 is fixedly connected to the inner side wall of the partition 6. The active gear 13 is connected to a threaded transmission shaft 17 via a transmission chain 16. The threaded transmission shaft 17 is rotatably installed in the partition 6 and threadedly connected to a threaded travel rod 18 above it. The threaded travel rod 18 is located at the bottom of the telescopic plate 9.

[0031] In another embodiment of the present invention, the threads between the threaded drive shaft 17 and the threaded travel rod 18 are inclined, so that the rotation of the threaded drive shaft 17 drives the threaded travel rod 18 to drive the telescopic plate 9 to move laterally.

[0032] In another embodiment of the present invention, a guide roller 11 is provided at the top of the partition 6.

[0033] In another embodiment of the present invention, a conveyor belt 7 is provided on the bottom of the lifting frame 4 and the surface of the partition 6.

[0034] In another embodiment of the present invention, preferably, a lifting platform 8 is provided at the bottom center of the lifting frame 4.

[0035] Detailed explanation of the operation process (partition 6 flips downwards 90°) Step 1: Start flipping partition 6 downwards: The front end of partition 6 rotates downward around fixing rod 12; Partition 6 changes from the horizontal bearing position to the vertical release position (90° flip); Since the active gear 13 is fixedly connected to the partition 6, the active gear 13 rotates synchronously by 90°.

[0036] Step 2: The driving gear 13 drives the threaded drive shaft 17 to rotate via the transmission gear chain 16. The drive gear 13 is equipped with a gear or sprocket; One end of the transmission gear chain 16 is fitted onto the drive gear 13, and the other end is connected to the threaded transmission shaft 17; When the drive gear 13 rotates, it transmits torque to the threaded drive shaft 17 through the transmission gear chain 16, driving the threaded drive shaft 17 to rotate around its own axis.

[0037] It should be noted that even if the angle of the drive pinion 13 changes in space (due to the flipping of the partition 6), the transmission can still be maintained as long as the transmission chain 16 has a certain degree of flexibility (such as using a chain or universal joint).

[0038] Step 3: The rotation of the threaded drive shaft 17 drives the threaded travel rod 18 to move linearly. The threaded drive shaft 17 and the threaded travel rod 18 form a screw-nut pair (or in the opposite direction). Rotation of threaded drive shaft 17 → Threaded travel rod 18 extends or retracts in a straight axial direction (depending on the direction of thread). Reverse process: When the partition 6 is reset to the horizontal position, the drive gear 13 rotates in the reverse direction → the threaded drive shaft 17 reverses direction → the telescopic plate 9 retracts.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. 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. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
