Description

Technical Field

[0001] This utility model relates to the field of destacking systems, specifically a double-truss suction cup destacking device. Background Technology

[0002] The depalletizing system scans and identifies the position and stacking structure of objects, then uses a robotic arm or fixed suction cups to disassemble them one by one and place them in designated locations. The depalletizing process can be adjusted in real time with the help of sensors and vision systems based on pre-set algorithms and rules. Palletizing and depalletizing are of great significance in practical applications. They can not only reduce the risks of manual operation and improve work efficiency, but also reduce error and damage rates. At the same time, robotic palletizing and depalletizing can stack and unpack various types and shapes of objects, making them suitable for various industries and products.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this embodiment provides a double-truss suction cup destacking device, including an unloading mechanism 1. Two unloading trusses 2 are installed inside the unloading mechanism 1. A longitudinal tank chain 3 is installed on the upper surface of each of the two unloading trusses 2. A transverse tank chain 4 is installed at one end of each unloading truss 2 on the upper surface of the unloading mechanism 1. A destacking suction cup 5 is installed at one end of the longitudinal tank chain 3 on the side surface of the unloading truss 2. A PLC motion controller is externally connected to the unloading mechanism 1. A visual recognition module is installed on one side of the destacking suction cup 5. The destacking suction cup 5 has a built-in pressure sensor. The upper end of the destacking suction cup 5 is connected to the free end of the transverse tank chain 4 with a hydraulic cylinder. The free end of the transverse tank chain 4 is fixedly connected to the unloading truss 2. The bottom conveyor belt 6 is set below the destacking suction cup 5 on the inner side of the unloading mechanism 1. The two sides of the bottom conveyor belt 6 are provided with guide grooves 13 on the side surface of the unloading mechanism 1. The upper surface of the bottom conveyor belt 6 is connected to the lifting rope 11. The other end of the lifting rope 11 is mounted on the unloading mechanism 1 with a winding roller 12.

[0022] like Figure 2-3 As shown, in this embodiment, an unloading conveyor belt 7 is installed on the inner side of the unloading mechanism 1 at the end away from the transverse tank chain 4. Two guide plates 8 are installed on the upper surface of the unloading conveyor belt 7. The two guide plates 8 are arranged in a cone shape above the unloading conveyor belt 7. An angle adjustment screw is connected between the upper part of the unloading conveyor belt 7 and the guide plates 8. A material tray 9 is installed on the upper surface of the bottom conveyor belt 6. Both the bottom conveyor belt 6 and the unloading conveyor belt 7 are connected to a servo motor. The unloading truss 2 at the end away from the transverse tank chain 4 is located on the upper surface of the unloading mechanism 1 and a moving guide rod 10 is installed. The material to be unloaded is placed above the material tray 9.

[0023] The working principle of this utility model is as follows: During use, the entire stack is placed on top of the material pallet 9. A forklift lifts the material pallet 9 above the bottom conveyor belt 6. The bottom conveyor belt 6 is then controlled to move the material pallet 9 to one side. The visual system on the outside of the depalletizing suction cup 5 scans the stack, generating position data and marking the packaging to be unpacked. A PLC motion controller is used to plan the movement trajectory of the two unloading gantry 2, adjusting the two depalletizing suction cups 5 above the target packaging. A hydraulic straight mechanism controls the suction cups 5 to press down and adaptively adhere to the packaging surface, using negative pressure suction... Then, by using the longitudinal tank chain 3 and the transverse tank chain 4 on the two unloading gantry 2 to lift and transfer the package to the position above the unloading conveyor belt 7, the negative pressure is released to complete the destacking. The rotation of the unloading conveyor belt 7 is used to transport the material. The guide plate 8 set on the unloading conveyor belt 7 can be used to guide the flow of the material. After the material on the material pallet 9 is absorbed and the height is reduced, the lifting rope 11 is wound up by the control take-up roller 12. After the lifting rope 11 pulls the bottom conveyor belt 6 up, the bottom conveyor belt 6 moves upward inside the guide chute 13, which facilitates the subsequent destacking operation.
