Description

Technical Field

[0001] This utility model belongs to the field of stacker manufacturing technology, specifically relating to a tilting destacking machine. Background Technology

[0002] Stacker cranes are the core equipment of automated storage and retrieval systems (AS / RS), their main function being to complete the inbound and outbound operations of goods by moving along tracks between racks. The functionality of a stacker crane is mainly achieved through the coordinated operation of three main mechanisms: a horizontal running mechanism, a vertical lifting mechanism, and a fork extension mechanism. The most commonly used horizontal running structure is a conveyor belt. However, the goods transported within a stacker crane are often multi-layered, numerous, and heavy. Directly dumping these goods onto the conveyor belt can result in excessive load on the conveyor belt at one time, causing it to malfunction and preventing normal transport. Therefore, existing technology requires further improvement. Utility Model Content

[0003] The purpose of this utility model is to provide a tilting depalletizer that can sort multi-layer stacked goods.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tilting destacking machine includes a tilting frame, a pressure-bearing frame fixedly connected to the center of the bottom surface of the tilting frame, a first servo cylinder installed inside the pressure-bearing frame, the base of the first servo cylinder fixed inside the pressure-bearing frame, the telescopic end of the first servo cylinder penetrating through the bottom surface of the tilting frame and connected to a lifting frame, the lifting frame connected to a first conveying device located above the bottom surface of the tilting frame, two opposite edges of the bottom surface of the tilting frame connected to an anti-tipping frame via a support frame, the upper end of the support frame rotatably connected to the tilting frame, the lower part of the support frame fixedly connected to the anti-tipping frame, one side edge of the tilting frame adjacent to the support frame connected to the anti-tipping frame via a second servo cylinder, the two ends of the second servo cylinder rotatably connected to the edge of the tilting frame and the anti-tipping frame respectively, the top surface of the tilting frame is provided with a first pressing device that can be lifted and lowered, two opposite sides of the tilting frame are provided with second pressing devices that can move into the tilting frame, and one side of the tilting frame adjacent to the second pressing device is provided with a second conveying device.

[0006] Furthermore, the tilting frame is a cuboid frame with a mesh-like bottom surface. The first pressing device includes several first rotating rollers, with rotating brackets rotatably connected to both ends of the first rotating rollers. A cylinder is connected to the rotating bracket, and the cylinder base is fixed on the connecting plate. The top wall of the tilting frame is provided with several parallel crossbars in the same plane. Two adjacent crossbars are connected to both ends of the connecting plate. The connecting plate is also provided with two vertically movable limiting rods, which are connected to the rotating bracket. The length direction of the limiting rods is the same as the length direction of the cylinder extension rod in the same plane. The length direction of the first rotating rollers is parallel to the top surface of the tilting frame.

[0007] Furthermore, the second pressing device includes a fixed frame, which is fixed to the side of the tilting frame. The fixed frame is fixedly connected to the base of the third servo cylinder, and the telescopic end of the third servo cylinder is connected to the pressing plate. The fixed frame is in the form of a grid.

[0008] Furthermore, the first conveying device includes several second rotating rollers, which are located on the same plane and have the same length direction. One of the second rotating rollers is connected to a motor at one end, the motor base is connected to a first fixed rod, the output end of the motor is connected to the shaft of the second rotating roller, and the other end of the second rotating roller is rotatably connected to a second fixed rod.

[0009] Furthermore, the second conveying device includes several third rotating rollers, which are wrapped with a conveyor belt. The two ends of the third rotating rollers are rotatably connected to a fourth fixed rod. The length direction of the fourth fixed rod is perpendicular to the bottom surface of the tilting frame, and the upper end of the conveyor belt is spaced from the edge of the top wall of the tilting frame.

[0010] Furthermore, the support frame includes several diagonal rods and vertical rods. The upper ends of the several vertical rods are connected by a horizontal tube. Two first fixed plates are connected to the horizontal tube. A rotating rod passes through the surface of the two first fixed plates. A triangular plate is rotatably sleeved on the rotating rod. The triangular plate is connected to the lower edge of the flipping frame, forming a structure in which the flipping frame can rotate along the axial plane of the rotating rod.

[0011] Furthermore, the lifting frame includes a grid-shaped bottom support, which is connected to a first fixed rod and a second fixed rod via uprights.

[0012] Furthermore, the anti-rollover frame is a rectangular frame with a grid pattern inside.

[0013] This invention can transport multi-layered stacked goods layer by layer. During transportation, the lifting and lowering of a portion of the first rotating rollers presses down goods that do not need to be transported, ensuring that the goods remain within the flipping frame. The extension of the second servo cylinder tilts the stacked goods toward the second conveying device. Goods that have not been pressed are transported out from the gap between the upper edge of the second conveying device and the first rotating roller. The lifting and lowering of the first servo cylinder can lift the goods that have been transported at the top layer upwards, and then move the remaining goods upwards, thus transporting them to the outside in one go, achieving goods sorting. After transportation is completed, the retraction of the second servo cylinder can return the flipping frame to a vertical state, allowing for the continued transportation of new multi-layered stacked goods.

The two ends of the connecting plate 904 are respectively connected to two adjacent crossbars 905. The connecting plate 904 is also provided with two vertically movable limiting rods 906. The limiting rods 906 are connected to the rotating brackets 902. The length direction of the limiting rods 906 is in the same plane as the length direction of the telescopic rod of the cylinder 903. The length direction of the first rotating rollers 901 is parallel to the top surface of the flipping frame 1. The second pressing device 10 includes a fixing frame 1001, which is fixed to the side of the tilting frame 1. The fixing frame 1001 is fixedly connected to the base of the third servo cylinder 11, and the telescopic end of the third servo cylinder 11 is connected to the pressing plate 12. The fixing frame 1001 is in the form of a grid. The first conveying device 5 includes several second rotating rollers 501, which are located on the same plane and have the same length direction. One end of one of the second rotating rollers 501 is connected to a motor 502. The base of the motor 502 is connected to a first fixing rod 503, and the output end of the motor 502 is connected to the shaft of the second rotating roller 501. The other end of the second rotating roller 501 is rotatably connected to a second fixing rod 504. The second conveying device 12 includes several third rotating rollers 121, which are wrapped with a conveyor belt 123. The two ends of the third rotating rollers 121 are rotatably connected to fourth fixed rods 122. The length direction of the fourth fixed rods 122 is perpendicular to the bottom surface of the tilting frame 1, and the upper end of the conveyor belt 123 is spaced from the edge of the top wall of the tilting frame 1.The support frame 6 includes several diagonal rods 601 and vertical rods 602. The upper ends of the vertical rods 602 are connected by horizontal tubes 603. Two first fixing plates 604 are connected to the horizontal tubes 603. A rotating rod passes through the surface of the two first fixing plates 604. A triangular plate 605 is rotatably fitted on the rotating rod. The triangular plate 605 is connected to the lower edge of the tilting frame 1, forming a structure in which the tilting frame 1 can rotate along the axial plane of the rotating rod.

The cylinder 903, the first servo cylinder 3, the second servo cylinder 8, the third servo cylinder 11, and the motor 502 are all connected to a PLC controller.

[0020] In use, when the tilting frame 1 is in a vertical position, the goods can be aligned with the opening side of the tilting frame 1. Multiple layers of stacked goods enter the tilting frame through the opening. Each layer contains six bags, but not limited to this number. During the entry process, the second rotating roller 501 at the bottom of the tilting frame 1 is driven by a motor to rotate, allowing the multiple layers of stacked goods to quickly enter the tilting frame 1. After entering the tilting frame 1, the extension rod of the third servo cylinder 11 extends, causing the pressure plate 12 to apply pressure to both sides of the multiple layers of stacked goods, preventing them from tipping over. Then, the first servo cylinder 3 is activated, and its extension end lifts the lifting frame 4, which in turn lifts the first conveying device 5. The control cylinder 903 presses down on the top layer of goods. At this time, the top layer of stacked goods is located at the interval between the upper edge of the second conveying device 12 and the first rotating roller 901. Because there are multiple first rotating rollers 901, PL... The controller controls the first rotating roller 901 above the bag of goods that needs to be unloaded to move upwards, while the remaining first rotating rollers 901 normally press down on the goods that do not need to be unloaded. The second servo cylinder 8 is adjusted to extend, and the tilting frame 1 rotates around the rotating rod. The goods tilt onto the second conveying device 12. The goods that are not pressed down by the first rotating roller 901 come out from the gap between the upper edge of the second conveying device 12 and the first rotating roller 901 and enter the next conveying device. Then, the controller controls the first rotating roller 901 above the other bag of goods that needs to be unloaded to move upwards, and then the remaining goods are sequentially conveyed out from the gap between the upper edge of the second conveying device 12 and the first rotating roller 901. When the top layer of goods is unloaded, the first servo cylinder 3 is adjusted to raise the stacked goods upwards again. The same operation is repeated to transport the goods out from the gap between the upper edge of the second conveying device 12 and the first rotating roller 901. During use, the motor rotation can also be adjusted to adjust the position of the stacked goods.
