[0002] The pallet conveying mechanism plays a crucial role in the automatic production line of many industries such as food and beverage, and its main function is to accurately convey the pallet to a specific position of the production line. Due to the differences in production process requirements and storage and movement methods of different products, various pallet conveying mechanisms with different structures need to be used in cooperation to meet the diversified production needs. In the current production environment pursuing high efficiency and high output, it is particularly urgent to simplify and combine the structure of the conveying mechanism to save time and improve production efficiency.

[0003] At present, the common pallet conveying structure mainly has two types of roller conveying and chain conveying. In actual application, due to the limitation of production layout, the pallet conveying not only needs to realize the basic conveying function, but also often needs to rotate the pallet to a specified direction to facilitate product stacking and subsequent movement and storage. However, too many transmission actions not only increase the complexity of the production process, but also significantly prolong the production time, thereby reducing the overall productivity.

[0004] In summary, the existing pallet conveying mechanism has the problems of too many transmission actions, long production time and low productivity. SUMMARY

[0006] To achieve the above-mentioned purpose, according to the first aspect of the embodiment of the present application, a belt transmission push-pallet mechanism is provided, which comprises a rack and a chain transmission assembly arranged on the rack. Further comprising: The belt transmission push-pallet mechanism comprises a pair of base plates fixedly connected in the ports of the rack, a belt transmission assembly arranged in the base plate, and a push-pallet assembly; The belt transmission assembly comprises rotating columns arranged on both sides of the base plate port through bearings, a pair of synchronous pulleys fixedly arranged on each rotating column, and a servo motor fixedly connected to the outside of the base plate and connected to the rotating column through a main shaft, and the two synchronous pulleys on the same side are connected through a synchronous belt; The push-pallet assembly comprises a push-pallet frame arranged in the base plate, a support fixedly connected to the four corners of the bottom surface of the push-pallet frame and arranged on the synchronous belt, an electric push rod rotatably arranged at the middle part of the bottom surface of the push-pallet frame, a push-pallet plate rotatably connected to the side surface of the push-pallet frame, and a swing arm fixedly connected to the push-pallet plate and rotatably connected to the end of the electric push rod through a shaft.

[0007] Further improvement lies in that each of the base plates is fixedly installed with a synchronous belt pressing plate through a fixing bolt, each of the synchronous belt pressing plates penetrates into the base plate and is pressed on the synchronous belt.

[0008] Further improvement lies in that each of the supports is fixedly connected on the synchronous belt through a fixing bolt.

[0009] Further improvement lies in that one side of the pushing stack frame is fixedly connected with a detection plate, and the end of one of the base plates is fixedly connected with an optoelectronic module through a fastening screw.

[0010] Further improvement lies in that the inner side of each of the base plates is fixedly installed with a guide rail for guiding sliding of the pushing stack frame, and the end of each of the guide rails is fixedly connected with a stop block.

[0011] Further improvement lies in that the side surface of the pushing stack frame is fixedly connected with a guide wheel at each of the four corners, and the two guide wheels on the same side are arranged in the guide rails on the same side.

[0012] Further improvement lies in that the surface of the pushing stack frame is fixedly connected with a buffer block one on the side of the pushing stack plate.

[0015] Compared with the prior art, the beneficial effects of the present application are: The design of the belt transmission pushing stack mechanism of the present application omits the rotating action of the stack plate in the original production process requiring rotating the stack plate, directly controls the pushing plate to push the stack plate to the designated position by the belt transmission on the original chain conveying mechanism, and waits for the next production process action. The combination of the pushing stack mechanism and the stack plate conveying mechanism not only shortens the production process time, meets high-speed production, and reduces the space occupied by the stack plate conveying mechanism in the factory layout, but also reduces the space requirement of the production equipment on the space layout, thereby being more suitable for most production environments.

It is used to input the stacking plate to the belt drive push stacking mechanism 3, and this embodiment will not be described in detail; It also includes: a belt drive push stacking mechanism 3, which includes a pair of base plates 31 fixedly connected in the port of the frame 1 and a belt drive assembly 32 and a push stacking assembly 33 arranged in the base plate 31; The belt drive assembly 32 includes rotating columns 321 rotatably arranged in the port of the base plate 31 on both sides through bearings, a pair of synchronous wheels 322 fixedly arranged on each rotating column 321, and a servo motor 323 fixedly connected outside the base plate 31 and having a main shaft connected with the rotating column 321, and the two synchronous wheels 322 on the same side are connected through a synchronous belt 324; Among them, each base plate 31 is fixedly installed with a synchronous belt pressing plate 325 through a fixed bolt, each synchronous belt pressing plate 325 penetrates into the base plate 31 and is pressed on the synchronous belt 324, and the synchronous belt pressing plate 325 is used to tension the synchronous belt 324 to make the transmission more stable; The push stack assembly 33 includes a push stack frame 331 disposed in the base plate 31, brackets 332 fixedly connected to the four corners of the bottom surface of the push stack frame 331 and disposed on the synchronous belt 324, an electric push rod 333 rotatably disposed in the middle of the bottom surface of the push stack frame 331, a push stack plate 334 rotatably connected to the side of the push stack frame 331, and a swing arm 335 fixedly connected to the push stack plate 334 and rotatably connected at its end to the rod end of the electric push rod 333 via a rotating shaft. Each bracket 332 is fixedly connected to the synchronous belt 324 by fixing bolts. It should be noted that the belt drive assembly 32 and the pusher assembly 33 in the chain drive assembly 2 and the belt drive pusher mechanism 3 are both controlled by an external PLC controller. This part is existing technology and the control principle has been disclosed. This embodiment will not go into detail. In this embodiment, specifically, a detection plate 336 is fixedly connected to one side of the push stack 331, and a photoelectric module 337 is fixedly connected to the end of one of the base plates 31 by fastening screws. The photoelectric module 337 is used to detect the stack signal. In this embodiment, there is also a preferred implementation: a guide rail 338 for guiding the sliding of the push stack 331 is fixedly installed on the inner side of each substrate 31. A stop block 311 is fixedly connected to the end of each guide rail 338. Guide wheels 301 are fixedly connected to the four corners of the side of the push stack 331. Two guide wheels 301 on the same side are respectively set in the guide rail 338 on the same side, guiding the sliding on both sides, making the sliding more stable.

[0020] In this embodiment, there is also a preferred implementation: a buffer block 302 is fixedly connected to the surface of the pusher frame 331 on one side of the pusher plate 334. The buffer block 302 is used for buffering the back of the pusher plate 334. A notch 303 for mounting the pusher plate 334 is opened on the side of the pusher frame 331. A stop bar 304 is fixedly installed in one side port of the base plate 31. A buffer block 305 is fixedly connected to the stop bar 304. The buffer block 305 is used for buffering the side of the pusher frame 331.

[0021] In this embodiment, it should also be noted that the pallet conveying mechanism in the application is one of the important mechanisms in various automated production lines, and is often used in conjunction with palletizing mechanisms, depalletizing mechanisms, etc. Furthermore, it should be noted that this application only addresses the shortcomings of existing pallet conveying mechanisms, such as excessive transmission movements, long production time, and low capacity, and does not involve other aspects. The improvement is achieved by designing a belt-driven pallet pushing mechanism 3 to solve the problems in the background technology.

[0022] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: In use, the solution of this invention first involves the pallet entering through the chain conveyor inlet of the chain drive assembly 2. When the pallet is conveyed to (… Figure 1 When the position shown is reached, the photoelectric module 337 detects a signal, and the external PLC controller stops the chain drive assembly 2. At this time, the electric push rod 333 extends, causing the swing arm 335 to rotate and drive the pusher plate 334 to extend to the flat position. Then, the servo motor 323 starts to rotate forward, driving the synchronous belt 324 and the pusher frame 331 to drive the transmission. At this time, the guide wheels 301 on both sides of the pusher assembly 33 move horizontally in the two guide rails 338 in the base plate 31, and the pusher plate 334 pushes the pallet to the designated production station to wait for stacking.

[0023] Subsequently, the servo motor 323 reverses, driving the pusher frame 331 to reset. At this time, the electric push rod 333 retracts, causing the pusher plate 334 to retract and wait for the next plate to be driven to the pusher position. The above actions are repeated to complete the pusher action. The cyclical action meets the requirements of the production process. The present invention utilizes a belt-driven pusher mechanism 3 installed on a chain conveyor to facilitate pallet transport. This eliminates the need for pallet rotation in traditional production processes, allowing the belt drive to directly push the pallet to a designated position on the existing chain conveyor, awaiting the next production step. This combined use of the pusher mechanism and pallet conveyor not only shortens production time but also reduces the space required for the pallet conveyor in the factory layout, lowering the space requirements for production equipment and making it more suitable for most production environments.

[0024] The above-disclosed embodiments are only a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
