Description

Technical Field

[0001] This utility model relates to the technical field of logistics equipment, and in particular to an automatic depalletizing and unpalletizing equipment for container cages. Background Technology

[0002] In express logistics processing centers, to improve operational efficiency and reduce labor costs, logistics companies are using a new type of containerized cage for various stages of express delivery operations. These cages require depalletizing, stacking, handling, and storage at each stage of receiving, transferring, and dispatching, especially in sorting and transfer areas where numerous repetitive depalletizing and stacking operations are necessary. However, in current practices, forklifts are often used to stack the cages before transferring them to storage locations. Furthermore, when depalletizing is required, forklifts are needed to move the stacked cages to designated workstations, and sometimes forklifts are used for depalletizing as well. These processes are inefficient, prone to uneven stacking leading to collapse, and result in low safety and low work efficiency. Utility Model Content

By precisely controlling the merging and conveying process of the packages, the flow direction and speed of the products can be controlled, and the damage rate of the packages in the entire conveying process can be greatly reduced.

[0004] To achieve the above objectives, this utility model discloses an automatic depalletizing and unpalletizing device for container cages, including several conveyor lines and a depalletizing and unpalletizing mechanism. The several conveyor lines are connected end to end, and the depalletizing and unpalletizing mechanism is located at the end of the conveyor lines, so that the conveyor lines can send multiple stacked container cages or a single container cage into the depalletizing and unpalletizing mechanism. The destacking and stacking mechanism includes a frame and a clamping mechanism. The frame is fixedly installed on the conveyor line, and the clamping mechanism is slidably installed on the frame.

The rear bottom of the stacking and unstacking mechanism is provided with a positioning mechanism for restricting the container cage to a designated position in the frame. The lower sides of the clamping mechanism are provided with correction mechanisms, which abut against the side walls of the container cage to correct the container cage under the guiding action of the correction mechanisms.

A positioning groove is provided on the top surface of the conveyor line to engage with the positioning post. The positioning block is driven to rotate by a positioning drive device to intercept the container cage on the conveyor line.

[0006] Furthermore, the correction mechanism includes a correction wheel and a correction arm. The correction wheel is rotatably mounted on one end of the correction arm, and the other end is rotatably mounted on the frame. The correction arm is driven by a correction drive device to make the correction wheel swing.

[0007] Furthermore, the clamping mechanism includes a lifting platform, a first clamping plate, and a second clamping plate. The lifting platform is movably mounted on the frame.

A clamping drive device drives the first and second clamping plates to move close to or away from each other to clamp the container cage. The bottom of the first and second clamping plates is provided with grooves to support the bottom of the container cage. The lifting drive device drives the first and second clamping plates to lift the container cage.

[0008] Furthermore, a vision module is provided in the middle of the frame to monitor the stacking status of the container cages in real time.

[0009] Furthermore, the conveyor line includes pairs of guide rails and pairs of conveyor chains. Several trays are arranged between the guide rails along the length direction. The conveyor chains are rotatably mounted on the guide rails and are driven to rotate by a conveyor drive device for conveying the container cages.

[0010] Furthermore, a first guide plate and a second guide plate are respectively provided on both sides of the inlet end of the conveyor line. The ends of the first guide plate and the second guide plate away from the conveyor line are arranged in an outward "V" shape. An interception mechanism is provided between the first guide plate, the second guide plate and the conveyor line to intercept the container cage entering the conveyor line.

[0011] Furthermore, the interception mechanism includes an interception block, which is rotatably disposed on one side of the conveyor line. The interception block is driven to rotate by an interception drive device, so that the interception block blocks the container cage of the first guide plate and the second guide plate.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings.

[0015] Reference Figure 1 , Figure 2 As shown, an automatic depalletizing and depalletizing device for container cages includes a conveyor line 1 and a depalletizing and depalletizing mechanism 2. The depalletizing and depalletizing mechanism 2 is located at the middle of the conveyor line 1. In this embodiment, a first guide plate 12 and a second guide plate 13 are respectively provided on both sides of the entrance end of the conveyor line 1. The ends of the first guide plate 12 and the second guide plate 13 away from the conveyor line 1 are arranged in an outward "V" shape. A single container cage 6 or multiple stacked container cages 6 are pushed onto the first guide plate 12 and the second guide plate 13 by an AVG vehicle or a worker, so that the conveyor line 1 sends the single container cage 6 or multiple stacked container cages 6 into the depalletizing and depalletizing mechanism 2 for stacking or depalletizing work.

[0016] Reference Figure 3 As shown, in this embodiment, the conveyor line 1 includes a pair of guide rails 10 and a pair of conveyor chains 11. Several support plates are arranged between the guide rails 10 along the length direction. A sprocket is fixedly installed on the end of the conveyor roller. The conveyor chain 11 is tensioned on the sprocket so that the conveyor chain is rotated on the guide rail 10 and supported by the guide rail, which greatly improves the load-bearing capacity of the conveyor chain 11. A conveyor drive device is fixedly installed between the guide rails 10. The conveyor drive device is preferably a geared motor, and its output shaft is connected to one of the drive rollers. When a single container or multiple container cages are placed on the conveyor line 1, the conveyor drive device drives the conveyor chain 11 to rotate for conveying the container cages.

[0017] Reference Figure 1 , Figure 8 , Figure 9 As shown, more preferably, in this embodiment, interception mechanisms 14 are provided on both sides of the inlet end of the conveyor line 1. The interception mechanism 14 includes an interception block 141, an interception drive device 142, and an interception seat 143. The interception seat 143 is fixedly disposed on one side of the conveyor line, and the interception drive device is fixedly installed on the upper part of the interception seat 143. The end of the interception block is provided with a shaft, and the shaft of the interception block 141 is rotatably disposed on the lower part of the interception seat 143 through a bearing. In this embodiment, the interception drive device 142 is preferably a servo motor, and a third drive sprocket is fixedly disposed on its output shaft. A third sprocket is fixedly disposed on the end of the shaft of the interception block 141, and the third sprocket and the third drive sprocket are connected by chain drive.

[0018] After the container cage 6 is fed into the conveyor line 1, the interception drive device 142 drives the interception block 141 to rotate, so that the interception block 141 blocks the container cage in the first guide plate 12 and the second guide plate 13. After the container cage on the conveyor line is conveyed forward, the interception drive device 142 drives the interception block 141 to reset, so that the lifting conveyor mechanism sends the container cage 6 in the first guide plate 12 and the second guide plate 13 into the conveyor line 1, thereby realizing the orderly conveying of the container cage.

[0019] Preferably, a nylon plate is fixedly installed on the interceptor block 141 to prevent the interceptor block from deforming or being damaged.

[0020] Reference Figure 1 , Figure 3 As shown, the destacking and stacking mechanism 2 further includes a frame 21 and a clamping mechanism 22. The frame 21 is fixedly installed on the conveyor line 1, and the clamping mechanism 22 is vertically mounted on the frame 21. A lifting drive device is fixedly installed in the frame 21. The lifting drive device 23 drives the clamping mechanism 22 to lift and lower, so that the clamping mechanism 22 clamps the container cage, thereby destacking or stacking the container cage.

[0021] Combination Figure 3, Figure 6 As shown, in this embodiment, support feet 61 are respectively provided at the bottom diagonal of the container cage 6, and the bottom of the support feet has a groove 611. Support columns 62 are provided at the top diagonal of the container cage 6, so that when stacking, the grooves 611 of the support feet 61 of the upper container cage 6 are placed on the support columns 62 of the lower container cage 6 (e.g., ...). Figure 10 As shown), to prevent the container cages 6 from collapsing when stacked, and to improve the stacking accuracy of the container cages, this embodiment provides a positioning mechanism 4 on the rear bottom of the stacking mechanism 2. The positioning mechanism 4 includes a positioning block 41, one end of which is provided with a rotating shaft. The rotating shaft of the positioning block 41 is rotatably mounted on the frame 21 through a bearing. A positioning drive device 42 is mounted on the frame 21. The positioning drive device 42 is preferably a servo motor. A drive sprocket is fixedly mounted on its output shaft, and a positioning sprocket is fixedly mounted on the rotating shaft. The positioning sprocket and the drive sprocket are connected by a chain drive.

[0022] Furthermore, a positioning post 411 is fixedly provided on the end of the positioning block 41 that is not connected to the frame 21. A positioning groove 16 is provided on the top surface of the conveyor line below the positioning block 41. The positioning block 41 is driven to rotate towards the inner side of the frame by the positioning drive device 42 until the positioning post of the positioning block 41 is inserted into the positioning groove 16. Thus, the positioning block 41 is used to intercept the container cage entering the frame 21 on the conveyor line 1, thereby ensuring that the container cage stays in the set position and realizing the automatic positioning and conveying of the container cage. At the same time, the insertion and cooperation between the positioning post and the positioning groove 16 can prevent the positioning block from deforming under the collision of the container cage.

[0023] Reference Figure 4 , Figure 7As shown, further, since the container cage is transported on a plane, it is prone to deviation during the transport process. Correction mechanisms 5 are provided on both sides of the lower part of the clamping mechanism 22. The correction mechanism 5 includes a correction wheel 51 and a correction arm 52. In this embodiment, the correction wheel 51 and correction arm 52 are a pair. The correction wheel 51 is rotatably mounted on one end of the correction arm 52, while the other end of the correction arm 52 has a rotating shaft rotatably mounted on the frame 21. A correction drive device 53 is also mounted on the frame 21. In this embodiment, the correction drive device 53 preferably uses a servo motor, and a second drive sprocket is fixedly mounted on its output shaft. A correcting sprocket is fixedly installed at the top of the rotating shaft of the correcting arm 52. The correcting sprocket is connected to the second drive sprocket via a second chain drive. A positioning detection module is installed in the frame. In this embodiment, an infrared sensor is preferably used. When the container cage enters the frame 21, after the positioning detection module detects the container cage, the correcting drive device 53 drives the correcting arm 52 to rotate toward the inner side of the frame 21, so that the correcting wheel 51 abuts against the outer wall of the container cage 6, so that the container cage 6 completes the correction under the guiding action of the correcting wheel 51, ensuring that the support legs of the upper container cage 6 and the support columns of the lower container cage 6 can be aligned during the stacking process.

[0024] Reference Figures 3-5 As shown, the clamping mechanism 22 includes a lifting platform 221, a first clamping plate 222, and a second clamping plate 223. The outer wall of the lifting platform 221 is slidably engaged with the inner wall of the frame. In this embodiment, the lifting drive device preferably adopts a geared motor, on which a main sprocket is fixedly mounted. A driven sprocket is rotatably mounted on the side wall of the frame. A third chain is connected between the main sprocket and the driven sprocket. The third chain is fixedly connected to the lifting platform 221 so that the lifting platform 221 can be lifted and lowered on the frame 21. The upper parts of the first clamping plate 222 and the second clamping plate 223 are slidably mounted on the lifting platform 221. A pair of clamping drive devices are fixedly installed on the lifting platform. In this embodiment, the clamping drive device can be a pneumatic push rod, an electric push rod, a hydraulic push rod, etc. Its telescopic end is fixedly connected to the first clamping plate 222 / second clamping plate 223. The clamping drive device drives the first clamping plate 222 and the second clamping plate 223 to move close to each other or separate from each other for clamping the container cage.

[0025] Grooves 224 are provided at the bottom of the first clamping plate 222 and the second clamping plate 223, so that the grooves of the first clamping plate 222 and the second clamping plate 223 support the bottom of the container cage, making the clamping of the container cage more stable and preventing the container cage from slipping.

[0026] During destacking, after the stacked container cages are fed into the frame, they are positioned and corrected by the positioning mechanism 4 and the correction mechanism 5. The lifting drive device 23 drives the first clamping plate 222 and the second clamping plate 223 to descend until the grooves of the first clamping plate 222 and the second clamping plate 223 reach the bottom of the container cage. As the clamping drive device drives the first clamping plate 222 and the second clamping plate 223 to move close together, the first clamping plate 222 and the second clamping plate 223 clamp the container cage and support the bottom of the container cage. The lifting drive device drives the lifting platform to lift the first clamping plate 222 and the second clamping plate 223, thereby lifting the upper container cage and separating it from the lower container cage.

[0027] Next, the positioning drive device 42 drives the positioning block 41 to swing upward, and the correction drive device 53 drives the correction arm 52 to swing outward in the direction of the frame, so that the conveyor line 1 sends the lower layer of container cage out of the frame 21. Then, the lifting drive device drives the first clamping plate 222 and the second clamping plate 223 to descend until the upper layer of container cage is placed on the conveyor line 1. The lifting drive device 23 drives the first clamping plate 222 and the second clamping plate 223 to rise and reset, while the upper layer of container cage 6 continues to be sent out of the frame 21 through the conveyor line 1, thereby realizing the automatic destacking of the stacked container cages.

[0028] During stacking, after a single container cage is fed into the frame, it is positioned and corrected by the positioning mechanism 4 and the correction mechanism 5. The lifting drive device 23 drives the first clamping plate 222 and the second clamping plate 223 to descend until the grooves of the first clamping plate 222 and the second clamping plate 223 reach the bottom of the container cage. As the clamping drive device drives the first clamping plate 222 and the second clamping plate 223 to move close together, the first clamping plate 222 and the second clamping plate 223 clamp the container cage and support the bottom of the container cage. The lifting drive device 23 drives the lifting platform 21 to lift the first clamping plate 222 and the second clamping plate 223.

[0029] Next, the conveyor line 1 sends the next container cage into the frame and, in the same way, positions and corrects it through the positioning mechanism 4 and the correction mechanism 5, aligning the support columns of the lower container cage with the support feet of the upper container cage. Then, the lifting drive device drives the first clamping plate 222 and the second clamping plate 223 to descend, stacking the upper container cage on the lower container cage. Then, the positioning drive device 42 drives the positioning block 41 to swing upward, and the correction drive device 53 drives the correction arm 52 to swing outward toward the frame 21, so that the conveyor line 1 sends the stacked container cages out of the frame, thereby realizing the automatic stacking of container cages.

[0030] Furthermore, a vision module is provided in the middle of the frame 21. In this embodiment, the vision module preferably adopts a high-definition industrial camera. The vision module monitors in real time whether the grooves 611 of the support feet 61 of the upper container 6 are aligned with the support columns 62 of the lower container 6. When the vision module detects a deviation in the alignment of the support feet 61 and support columns 62 in the stacking of the upper and lower container 6, it feeds back to the system and issues an alarm. In this embodiment, the system is a PLC, which will not be described again here. This uses vision to assist in checking the stacking situation, thereby ensuring the stability of the container stacking.
