In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0045] This application discloses a carton conveying system. (Refer to...) Figure 1 The carton conveying system includes:

[0046] The double-layer storage rack 100 has a first conveying surface and a second conveying surface for horizontally conveying cartons, with the first conveying surface being higher than the second conveying surface.

[0047] A carton lifting and shifting device 200 is located at the end of the double-layer storage rack 100 and is used to lift a carton at the second conveying surface height to the first conveying surface height.

[0048] A magnetic strip track 300 is laid on the ground and connects the carton lifting and shifting device 200 and the carton conveying destination; and...

[0049] The AGV carton forklift 400 is guided by magnetic strip rails 300 and is used to transport cartons at the second conveyor height to their destination.

[0050] The beneficial technical effects of the carton conveying system in this application are roughly as follows:

[0051] The double-layer storage rack 100 can be installed in a workshop to store a large number of cartons. When another workshop needs cartons, the cartons on the first conveyor surface can be transported stack by stack to the destination by the AGV carton forklift 400. After the cartons on the first conveyor surface are emptied, the cartons on the second conveyor surface can be lifted stack by stack to the height of the first conveyor surface by the carton lifting and shifting device 200. Then the AGV carton forklift 400 transports the cartons at the height of the first conveyor surface stack by stack to the destination. In general, the whole system can be used for large-scale transfer of cartons in multiple workshops without having to lay the conveyor belt throughout each workshop, which significantly improves space utilization. Moreover, the equipment investment cost is significantly lower, the power consumption is significantly reduced, and the later maintenance cost is also lower.

[0052] Specifically, the double-layer storage rack 100 includes: a storage frame 11, a first conveyor belt 12 and a second conveyor belt 13. The first conveyor belt 12 is installed on the top of the storage frame 11 and is arranged horizontally, and the second conveyor belt 13 is installed on the bottom of the storage frame 11 and is arranged horizontally. The first conveying surface is the conveying surface of the first conveyor belt 12, and the second conveying surface is the conveying surface of the second conveyor belt 13.

[0053] Reference Figure 1 and Figure 2 The carton lifting and shifting device 200 includes:

[0054] Support frame 21, with a carton lifting cavity inside the support frame 21, and a carton inlet at one end of the support frame 21;

[0055] The partition unit 22 is located at the other end of the support frame 21 and is used to block the cartons entering the carton lifting cavity.

[0056] Two sets of support units 23 are vertically slidably assembled on opposite sides of the support frame 21 to support the cartons entering the carton lifting cavity.

[0057] Two sets of lifting drive units 24 are mounted on the support frame 21 to drive the support unit 23 to move back and forth between a low position and a high position. The lifting drive units 24 and the support units 23 are arranged in a one-to-one correspondence.

[0058] Two sets of aligning units 25 are respectively assembled on opposite sides of the support frame 21 to align the high-positioned cardboard boxes from both sides to the middle. The aligning units 25 and the supporting units 23 are arranged in a one-to-one correspondence.

[0059] When the carton enters the support frame 21, the partition unit 22 can effectively prevent the carton from tilting due to inertia. After the carton is lifted from the low position to the high position, the aligning unit 25 can pat the two sides of the carton inward, so that when the carton in the high position is output, it is more neat and less prone to tilting, which is beneficial for subsequent use and transfer of the carton.

[0060] Specifically, there are two sets of partition units 22, which are respectively installed on opposite sides of the support frame 21. The two sets of partition units 22 are arranged at intervals. By setting two sets of partition units 22, the two corners of the carton that have just entered the support frame 21 are blocked and limited, so that the limiting and buffering effect is better and the carton at the top is less likely to tilt forward.

[0061] In this embodiment, the partition unit 22 includes: vertically arranged angle steel 221 and multiple connecting plates 222 connected between the angle steel 221 and the support frame 21. The angle steel 221 is used to partition the corners of the carton. The partition unit 22 designed above has a simple and sturdy structure, is relatively easy to manufacture and install, and has low cost.

[0062] In this embodiment, the supporting unit 23 includes a supporting frame 231 and multiple supporting rollers 232. The multiple supporting rollers 232 are arranged in parallel and spaced apart. The supporting rollers 232 are rotatably assembled in the supporting frame 231. The supporting rollers 232 are arranged horizontally and their rotation axis is perpendicular to the direction of carton entry.

[0063] The partition unit 22 designed above has a simple and sturdy structure. During the process of the carton entering, the support roller 232 can roll and rub against the bottom of the carton, making the carton entering more efficient. Moreover, the entire partition unit 22 is lightweight, which makes it easier for the lifting drive unit 24 to lift the partition unit 22 with less effort.

[0064] To make the support unit 23 more stable and secure when it is raised and lowered, two vertically spaced guide rods 211 are provided on the side of the support frame 21. A guide cylinder 233 is slidably mounted on the guide rods 211 on the support frame 231. The guide rods 211 pass through the support frame 231 and the guide cylinder 233, which indirectly helps to lift the carton stably.

[0065] In this embodiment, the lifting drive unit 24 includes a first servo motor 241 and a first lead screw 242. The first lead screw 242 is arranged vertically and rotatably mounted on the side of the support frame 21. The first lead screw 242 passes through a portion of the support unit 23 and the two are threadedly connected. The first servo motor 241 is mounted on the side of the support frame 21, and the output shaft of the first servo motor 241 is connected to the end of the first lead screw 242.

[0066] When the first servo motor 241 is working, it will drive the first lead screw 242 to rotate forward or reverse, thereby driving the support unit 23 to rise or fall. The lifting drive unit 24 designed above has a simple and robust structure, is relatively easy to manufacture and install, and is low in cost and easy to operate.

[0067] In this embodiment, the aligning unit 25 includes: a clapping plate 251, a fixing frame 252, and a telescopic power component 253. The fixing frame 252 is installed on the side of the support frame 21, the telescopic power component 253 is installed inside the fixing frame 252, and the output end of the telescopic power component 253 is connected to the outside of the clapping plate 251.

[0068] The above-mentioned alignment unit 25 has a simple and robust structure, is easy to manufacture and install, and is low in cost and easy to operate.

[0069] Specifically, in order to improve the stability of the clapper 251 when clapping the carton, one clapper 251 corresponds to two sets of fixed frames 252 and two sets of telescopic power components 253. The fixed frames 252 and the telescopic power components 253 correspond one-to-one, and all the telescopic power components 253 open or close synchronously. At the same time, the telescopic power components 253 are preferably cylinders or electric push rods.

[0070] Reference Figure 3 and Figure 4 The AGV carton forklift 400 includes an AGV motion chassis 41, a support frame 42, a pushing unit 43, and a forklift unit 44. The support frame 42 is mounted on the AGV motion chassis 41. The forklift unit 44 is slidably mounted on the top of the support frame 42 in the front-back direction. The pushing unit 43 is mounted on the top of the support frame 42 and is used to drive the forklift unit 44 to slide back and forth.

[0071] By adding support frame 42, the basic height of forklift unit 44 is increased, thus eliminating the need to use the lifting function of forklift unit 44 itself to lift a stack of cartons to a relatively high position. During the forward and backward sliding process of push unit 43 pushing forklift unit 44, there is less risk of instability of center of gravity and less risk of tipping over, making it more stable and safer.

[0072] The AGV motion chassis 41 can be automatically positioned and moved using magnetic navigation, and it is a mature technology module in the existing technology, which can be directly purchased and used.

[0073] The support frame 42 includes a support panel 421 and four uprights 422. The uprights 422 are arranged at the bottom of the support panel 421, with the four uprights positioned at the four corners of the rectangle. The support frame 42 designed above is simple and robust, lightweight, and its cuboid structure provides good support, stably raising the base height of the forklift unit 44.

[0074] The upper surface of the support frame 42 is provided with slide rails 423 on both sides, and the bottom of the forklift unit 44 is provided with sliders 441 on both sides. The sliders 441 are slidably assembled with the slide rails 423. The slide rails 423 and the sliders 441 cooperate with each other to make the forklift unit 44 slide back and forth more stably.

[0075] The pushing unit 43 includes a second servo motor 431, a second lead screw 432, and a transmission block 433. The second lead screw 432 is rotatably mounted on the support frame 42 and located between two slide rails 423. The second lead screw 432 is arranged parallel to the slide rails 423. The transmission block 433 is fixedly installed on the bottom of the forklift unit 44. The second lead screw 432 passes through the transmission block 433 and the two are threadedly connected. The second servo motor 431 is mounted on the support frame 42, and the output shaft of the second servo motor 431 is connected to one end of the second lead screw 432.

[0076] The push unit 43 designed above has a simple structure and is easy to operate. Moreover, it can push the forklift unit 44 to any position within its stroke as needed, which is very convenient.

[0077] The support frame 42 is also equipped with a control box 45, which has a manual start button 451 and a manual stop button 452, making it convenient for staff to turn the entire AGV carton forklift 400 on and off as needed without having to bend over to operate it, making it more convenient.

[0078] The forklift unit 44 includes a forklift seat 442 and a front fork 443. The forklift seat 442 is equipped with a lifting module that drives the front fork 443 to rise and fall. The front end of the front fork 443 is tilted upward at 5-10 degrees. Since the carton has a certain weight, the upward tilting design of the front end of the front fork 443 can effectively prevent the carton from falling during forklift transportation, making it safer.

[0079] The minimum height of the forklift unit 44 is no less than 1 meter, which can better adapt to the current basic height of the packaging production line.

[0080] The forklift unit 44 can slide back and forth a distance of at least 1.2 meters, which is beneficial for the forklift unit 44 to transport larger cardboard boxes and has better adaptability.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
