Description

Technical Field

[0001] This utility model relates to the field of automated warehousing and logistics technology, specifically to an automated destacking and stacking device for turnover boxes. Background Technology

[0002] An automated storage and retrieval system (AS / RS) for tote boxes is a high-bay warehouse system that uses rack storage units to store tote boxes. It is mainly used for storing unitized goods in logistics systems such as those for electricity and tobacco. The inbound and outbound conveying system of the AS / RS primarily handles the outbound and inbound functions of the tote boxes.

[0003] Currently, the most common model for automated storage and retrieval systems (AS / RS) using turnover boxes in China is as follows: individual turnover boxes are stored in storage locations on shelves, and the inbound and outbound conveying system uses a simple single-layer conveyor line to realize the entry and exit of turnover boxes.

[0004] Existing automated storage and retrieval systems (AS / RS) for tote boxes have the following main problems: individual tote boxes are stored on shelves, resulting in significant wasted vertical space, making them unsuitable for AS / RS environments with limited height; for stacked tote boxes, single-layer conveyor buffering is insufficient to meet the requirements of simultaneous warehousing of multiple product types in limited space; and for defective unit goods, manual handling followed by direct warehousing makes it difficult to ensure the accuracy of information.

[0005] To address this, existing technology CN201802433769 describes a pneumatic destacking and stacking machine for turnover boxes, comprising a frame, a stopping mechanism, a lifting mechanism, and a telescopic support mechanism. The stopping mechanism and the lifting mechanism are both fixed to the bottom of the frame. Telescopic support mechanisms are respectively provided on both sides of the upper part of the frame. The lifting mechanism includes a first lifting cylinder, a lifting plate, and an inverted second lifting cylinder. The first lifting cylinder is fixed, and the end of the cylinder rod of the first lifting cylinder is fixedly connected to the end of the cylinder rod of the second lifting cylinder. The lifting plate is installed on the upper end of the cylinder body of the second lifting cylinder. The drawback of the above technical solution is that this application directly uses a telescopic support structure for load stacking, requiring high-precision cylinders, which increases wear and operating costs. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic destacking and stacking device for turnover boxes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic stacking and unstacking device for turnover boxes, comprising: a mounting frame with three sides enclosing and one side open; a lifting device for reciprocating vertical lifting and lowering is provided at the bottom of the mounting frame; telescopic rods are horizontally arranged on the enclosing surfaces on both sides of the mounting frame; at least one fork is rotatably mounted on the mounting frame; the telescopic rods drive the fork to rotate horizontally on the mounting frame; a stabilizing plate at the bottom of the fork abuts against the mounting frame and forms a triangle; a baffle rod is provided inside the mounting frame and on the enclosing surface adjacent to the fork; the movement direction of the lifting device is perpendicular to the rotation direction of the fork in the same horizontal plane; the fork is located at the top of the lifting device; and the maximum running distance of the lifting device is greater than the vertical distance of the fork from the mounting frame to the horizontal ground.

[0008] As a preferred embodiment of this application, material collection plates for shaping workpieces are provided on both sides of the mounting frame. The top of the material collection plate extends outside the mounting frame and is inclined in an outward flaring shape. A through groove is provided on the material collection plate for the lever to pass through.

[0009] As a preferred embodiment of this application, the top and bottom of the aggregate plate are fixed to the mounting frame by a connecting rod, and a gap is left between the mounting frame and the aggregate plate.

[0010] As a preferred embodiment of this application, reinforcing corner plates are provided at the sidewalls and bent surfaces of the aggregate plate.

[0011] As a preferred embodiment of this application, the lifting device includes: a lifting mechanism disposed within the mounting frame and a guide transmission component rotatably disposed on the lifting machine; the lifting machine includes: a support frame and a hydraulic cylinder disposed within the support frame, the hydraulic cylinder being connected to lifting rods located at the four ends of the support frame; the guide transmission component includes: a connecting frame fixedly connected to the top of the lifting rod, and rotating shafts sequentially disposed within the connecting frame, the rotating shafts being in the same direction of rotation as the shift fork.

[0012] As a preferred embodiment of this application, the telescopic rod and the shift fork are connected by a connecting rod. The piston end of the telescopic rod drives the connected connecting rod to move synchronously. The connecting rod is rotatably connected to the shift fork. Since the shift fork is rotatably mounted on the mounting frame, when the telescopic rod drives the connecting rod to move, the shift fork rotates through the through groove into the mounting frame or exits the through groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The three-sided enclosing design effectively limits the movement range of the turnover box, improving the stability and accuracy during the destabilization and stacking process. The fork is set on the top of the lifting device, and the maximum running distance of the lifting device is greater than the vertical distance of the fork from the ground on the mounting frame. This design ensures that the device can adapt to the destabilization and stacking operations of turnover boxes of different heights. Automated operation reduces manual intervention and improves the efficiency and quality of destabilization and stacking operations. In addition, the telescopic rod in this application is only used to control the rotation of the fork, reducing the stress on the telescopic rod. The stabilizing plate strengthens the load-bearing capacity of the fork, ensuring the stability of the fork during rotation. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5As shown, this application provides an automatic destacking and stacking device for turnover boxes, including: a quadrilateral mounting frame 1 with three sides enclosing and one side open; a lifting device 2 for reciprocating vertical lifting motion at the bottom of the mounting frame 1, which is used to lift the turnover boxes; telescopic rods 3 horizontally arranged on the enclosing surfaces on both sides of the mounting frame 1; and at least one fork 4 rotatably mounted on the mounting frame 1 (in actual operation, if there are corresponding forks 4 on both sides of the mounting frame 1, that is, two forks 4 are provided; this embodiment mainly shows the optimal installation method: that is, forks 4 are provided at both the front and rear ends of one side of the mounting frame 1, so this embodiment has a total of four forks 4). (Two of them are set opposite each other on the mounting frame 1). The telescopic rod 3 drives the fork 4 to rotate horizontally on the mounting frame 1, so that the fork 4 can rotate into the mounting frame 1 and extend into the bottom of the turnover box. The stabilizing plate 6 provided at the bottom of the fork 4 abuts against the mounting frame 1 and forms a triangle. A baffle rod 7 is provided in the mounting frame 1 and on the enclosing surface adjacent to the fork 4. The movement direction of the lifting device 2 is perpendicular to the rotation direction of the fork 4 in the same horizontal plane. The fork 4 is set on the top of the lifting device 2. At the same time, the maximum running distance of the lifting device 2 is greater than the vertical distance of the fork 4 on the mounting frame 1 to the horizontal ground.

[0023] The bottom of the shift fork 4 is equipped with a stabilizing plate 6, which cleverly contacts and supports the mounting frame 1, forming a stable triangular structure. This design not only enhances the stability of the shift fork 4 during operation but also effectively distributes the force of gravity, making the entire device more robust and durable under load. Through the mechanical advantages of the triangle, gravity is evenly distributed across multiple support points of the mounting frame 1, thus avoiding structural damage caused by excessive stress at a single point, further improving the safety and reliability of the entire stacking and destabilizing device.

[0024] The working principle of the automatic destacking and stacking device for turnover boxes described in this technical solution is as follows:

[0025] The main body of the device is a quadrilateral mounting frame 1, with three sides forming a closed section, while the other side is designed as an opening to facilitate the entry and exit of turnover boxes. At the bottom of the mounting frame 1, a lifting device 2 is configured, which can perform reciprocating vertical lifting and lowering movements. Its main function is to lift the turnover boxes to the required height.

[0026] Telescopic rods 3 are horizontally installed on both sides of the mounting frame 1. These telescopic rods 3 are responsible for driving the shift forks 4 to rotate horizontally on the mounting frame 1. The number and position of the shift forks 4 are key design points: in actual operation, shift forks 4 can be installed on both sides or one side of the mounting frame 1 as needed. This solution shows an optimized setting, that is, two shift forks 4 are installed on each side of the mounting frame 1 (e.g., at the front and rear ends), for a total of four shift forks 4, which are arranged in pairs opposite to each other on the mounting frame 1.

[0027] When the telescopic rod 3 is in operation, it will drive the shift fork 4 to rotate horizontally on the mounting frame 1 until the shift fork 4 enters the mounting frame 1 and extends into the bottom of the lifted turnover box. The bottom of the shift fork 4 is designed with a stabilizing plate 6. When the shift fork 4 rotates to the correct position, the stabilizing plate 6 will contact a part of the mounting frame 1, forming a triangular shape together. This design enhances the stability of the shift fork 4 during operation.

[0028] Inside the mounting bracket 1, on the enclosing surface adjacent to the shift fork 4, a stop bar 7 is provided. This design helps to provide additional support or guidance when the shift fork 4 operates the turnover box, ensuring that the turnover box can move in the expected direction and position.

[0029] The key kinematic relationship is that the direction of movement of the lifting device 2 and the direction of rotation of the shift fork 4 are perpendicular to each other in the same horizontal plane. This means that when the lifting device 2 raises the turnover box to a certain height, the shift fork 4 can rotate horizontally to enter the bottom of the turnover box for subsequent folding or destacking operations. Furthermore, the shift fork 4 is positioned at the top of the lifting device 2, ensuring operational continuity. Simultaneously, the maximum operating distance of the lifting device 2 is designed to be greater than the vertical distance of the shift fork 4 from the mounting frame 1 to the horizontal ground, ensuring that the shift fork 4 has sufficient working space to operate turnover boxes at different heights.

[0030] initial state

[0031] The turnover box is located on one side of the opening of the device, waiting to be processed.

[0032] The lifting device 2 is in its lowest position.

[0033] The shift fork 4 is driven by the telescopic rod 3 and is in a non-working state outside the mounting bracket 1.

[0034] The stop bar 7 is in the preset position, ready to guide or support the turnover box.

[0035] Lifting turnover box

[0036] Start lifting device 2: Lifting device 2 begins to perform vertical lifting action, raising it upwards until its top touches the bottom of the turnover box.

[0037] Stable lifting: Lifting device 2 continues to lift, steadily raising the turnover box to a certain height, at which point the bottom of the turnover box is off the ground. Operation of fork 4.

[0038] The fork 4 rotates into place: At the same time or after the lifting device 2 raises the turnover box, the telescopic rod 3 begins to move, causing the fork 4 to rotate horizontally on the mounting frame 1. The fork 4 gradually enters the interior of the mounting frame 1 until its bottom extends below the bottom of the turnover box.

[0039] Triangular support is formed: The stabilizing plate 6 at the bottom of the shift fork 4 contacts the mounting bracket 1, together forming a triangular shape, providing stable support for the shift fork 4. Folding or destacking operation.

[0040] The fork 4 clamps the turnover box: Under the stable triangular support, the fork 4 moves further to clamp the bottom of the turnover box. At this time, the lifting device 2 can remain in the raised state, or the height can be adjusted as needed.

[0041] Moving the turnover box: Under the grip of the lever 4, the turnover box is moved according to a preset direction and position by the extension and retraction of the telescopic rod 3 and the rotation of the lever 4. This may involve separating the turnover box from a stack (destacking) or combining multiple turnover boxes into a new stack (folding).

[0042] Material stop bar 7 assists in operation: During the movement of the turnover box, the material stop bar 7 plays a guiding or supporting role, ensuring that the turnover box can be moved to the target position smoothly and accurately.

[0043] End operation

[0044] Release fork 4: When the turnover box reaches the target position, fork 4 releases its grip on the turnover box, ready for the next operation.

[0045] Lifting device 2 resets: Lifting device 2 begins to descend and returns to its initial position, preparing to process the next turnover box.

[0046] Telescopic rod 3 resets: Telescopic rod 3 drives the shift fork 4 back to the non-working state outside the mounting bracket 1, waiting for the next operation command.

[0047] To improve the neatness of the turnover boxes, ensure that the center of gravity of the turnover boxes is consistent when they are placed, and facilitate the smooth action of the shift fork 4 on the turnover boxes, material collection plates 8 for shaping the workpieces are provided on both sides of the mounting frame 1. The top of the material collection plate 8 extends outside the mounting frame 1 and is inclined in an outward flared shape. The material collection plate 8 is provided with a through groove 81 for the shift rod to pass through.

[0048] To ensure the stability and flexibility of the aggregate plate 8 and further improve the stability of the mounting frame 1, the top and bottom of the aggregate plate 8 are fixed to the mounting frame 1 by a connecting rod 82, and a gap is left between the mounting frame 1 and the aggregate plate 8.

[0049] To enhance the load-bearing capacity of the aggregate plate 8 at the side walls and bent surfaces, thereby improving the strength and stability of the aggregate plate 8, reinforcing corner plates 83 are provided at the side walls and bent surfaces of the aggregate plate 8.

[0050] The lifting device 2 includes: a lifting machine 21 disposed within the mounting frame 1 and a guide transmission component 22 rotatably disposed on the lifting machine 21. The lifting machine 21 includes: a support frame 211 and a hydraulic cylinder 212 disposed within the support frame 211. The hydraulic cylinder 212 is connected to lifting rods 213 located at the four ends of the support frame 211. In this application, the lifting rods 213 at the four ends are synchronously raised and lowered by the extension and retraction of the hydraulic cylinder 212, thereby effectively supporting the turnover box. This structure adopts existing technology and is not the main technical solution of this application, so it will not be described in detail. The guide transmission component 22 includes: and The top of the lifting rod 213 is fixedly connected to the connecting frame 221. Rotating shafts 222 are sequentially arranged in the connecting frame 221. The rotating shafts 222 rotate in the same direction as the fork 4. The guide transmission component 22 is mainly used to support the turnover box transported by the logistics conveyor belt. In actual operation, the guide transmission component 22 in this application can be driven by an external drive motor equipped with a transmission belt to rotate the guide transmission component 22, so that the turnover box moves to abut against the baffle rod 7 in the mounting frame 1, thereby realizing the shaping of the turnover box (since this rotation transmission mechanism is also existing technology and easy to understand, it will not be described in the figure).

[0051] The telescopic rod 3 and the shift fork 4 are connected by a connecting rod 5. The piston end of the telescopic rod 3 drives the connected connecting rod 5 to move synchronously. The connecting rod 5 is rotatably connected to the shift fork 4. Since the shift fork 4 is rotatably mounted on the mounting frame 1, when the telescopic rod 3 drives the connecting rod 5 to move, the shift fork 4 rotates through the through groove 81 into or out of the through groove 81, realizing the linkage control between the telescopic rod 3 and the shift fork 4, providing key technical support for the automated operation of the device. At the same time, this design allows the shift fork 4 to rotate flexibly and act on the turnover box, improving the flexibility and accuracy of the device.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
