Description

Technical Field

[0001] This utility model relates to the field of cargo transportation, and in particular to a conveying device for a palletizing and depalletizing workstation. Background Technology

[0002] A palletizing / depalletizing workstation is an integrated piece of equipment in the field of industrial automation used to disassemble stacked materials and organize loose materials into neat stacks. Its core function is to replace manual labor in repetitive and high-intensity material handling and stacking operations, and it is widely used in production, warehousing, and logistics. Essentially, it achieves precise material gripping, movement, and positioning through the collaboration of mechanical structures, control systems, and sensors, thereby improving operational efficiency and safety.

[0003] Existing transport equipment for palletizing and depalletizing workstations mostly relies on planar conveyor systems such as conveyor chains or conveyor belts to transport palletized goods. When the pallet and stacked goods are transported to the unloading position, the unloading robot must unload them before the empty pallet can move to the loading position to load more goods. This process involves long unloading and loading times, resulting in low efficiency. Furthermore, existing pallet systems mostly use simple limiting structures such as baffles or blocks to maintain the position of goods. When the stacked goods are disc-shaped, these limiting structures have low adaptability, easily causing swaying and shifting during movement, affecting the stability of the goods. Utility Model Content

[0004] To address the aforementioned issues, this application provides a conveying device for a palletizing / depalletizing workstation.

[0005] To achieve the above objectives, this application provides the following technical solution: a conveying device for a palletizing and depalletizing workstation, comprising a conveyor belt, wherein the conveyor belt is equipped with two synchronously movable conveying platforms, and each conveying platform is detachably connected to a placement table via a column. After the goods are stacked on the placement table, the two conveying platforms move back and forth along the distribution direction of the conveyor belt, and the two placement tables and the goods stacked on their surfaces continuously switch positions.

[0006] The conveying platform and the placement platform are equipped with rotatable drive rings in the gap space. Above each drive ring are multiple drive frames equidistantly distributed along a circular trajectory. The end of each drive frame near the outer side of the conveying platform is detachably connected to a limit rod. As the multiple drive frames move synchronously, the multiple limit rods can move synchronously closer to or away from the circular goods.

[0007] Furthermore, each drive ring has an internal gear ring fixed to its inner side, and each conveying platform is equipped with an electric gear that meshes with the internal gear ring. As the electric gear rotates, the drive ring and the internal gear ring rotate synchronously.

[0008] Furthermore, the inner side of the internal gear ring is meshed with multiple linkage gears equidistantly distributed along a circumferential trajectory. Each linkage gear 1 is connected to a linkage gear 2 via a synchronous shaft coaxially distributed above it. The synchronous shaft is installed on the lower surface of the placement platform. Multiple drive frames located below the same placement platform are meshed with multiple linkage gear 2. As the drive ring and internal gear ring rotate, multiple sets of linkage gears 1 and linkage gear 2 rotate synchronously, and multiple drive frames and limit rods move synchronously.

[0009] The placement platform is equipped with multiple receiving channels. When the drive frame moves, the limiting rod moves within the receiving channel.

[0010] Furthermore, each of the conveying platforms is equipped with an annular guide rail, and each drive ring is rotatably mounted on the inner side of the annular guide rail.

[0011] Furthermore, limit sliders are fixed on both sides of the drive frame, and multiple sets of symmetrically distributed linear guides are installed on the conveying platform. The limit sliders are slidably connected to the linear guides. When the drive frame moves, the limit rods and limit sliders move along the distribution direction of the linear guides.

[0012] Furthermore, each of the limiting rods is equipped with a first limiting ring and a second limiting ring distributed from top to bottom, with the first limiting ring and the second limiting ring respectively abutting against the upper and lower ends of the drive frame.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] As the conveyor belt operates continuously, the two placement platforms and the goods stacked on their surfaces move to the unloading position, receiving unloading operations from robotic arms or other transport equipment. Simultaneously, replenishment operations can be performed on the other placement platform. This operating mode effectively avoids transport interruptions or excessively long waiting times caused by unloading and replenishment, significantly improving the efficiency of palletized goods transport and unloading. Furthermore, multiple limit bars enable precise palletizing and depalletizing operations, preventing swaying and offset of round goods, thus improving the accuracy and stability of round goods distribution.

[0022] 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.

[0023] Example: Reference Figure 1-4 The conveying equipment for a palletizing and depalletizing workstation shown includes a conveyor belt 1, on which two synchronously movable conveying platforms 2 are installed. The center position of the conveyor belt 1 is the unloading position. In this utility model, one of the two conveying platforms 2 is always in the unloading position.

[0024] Specifically, each conveyor platform 2 is detachably connected to a placement platform 22 via a column 21. After the goods are stacked on the placement platform 22, the two conveyor platforms 2 move back and forth along the distribution direction of the conveyor belt 1, and the two placement platforms 22 and the goods stacked on their surfaces continuously switch positions.

[0025] In actual operation, both empty and empty placement platforms 22 can receive stacked round goods. After the round goods are stacked, the conveyor belt 1 is started, and both fully loaded placement platforms 22 move synchronously with the conveyor platform 2. After the round goods stacked on the first placement platform 22 located at the center of the conveyor belt 1 are unloaded, the second placement platform 22 near the end of the conveyor belt 1 moves to the unloading position at the center of the conveyor belt 1 to accept the unloading operation.

[0026] At this time, since the first placement platform 22 is unloaded, the stacked round goods can be simultaneously transferred to the first placement platform 22 during the unloading operation of the second placement platform 22. After the round goods stacked on the second placement platform 22 have been unloaded, the first placement platform 22, which is fully loaded, moves back to the unloading position of the conveyor belt 1 to accept the unloading operation, while the second placement platform 22, which is unloaded, can be located on the other side of the conveyor belt 1 to receive stacked round goods again.

[0027] Subsequently, as the conveyor belt 1 continues to operate, the two placement platforms 22 and the goods stacked on their surfaces continuously move to the unloading position, receiving unloading operations from robotic arms or other transportation equipment. When one placement platform 22 and the goods stacked on its surface continuously move to the unloading position, a replenishment operation can be performed on the other placement platform 22. This operation mode can effectively avoid transportation interruptions or excessively long waiting times caused by unloading and replenishment, effectively improving the efficiency of palletized goods transportation and unloading.

[0028] Rotatable drive rings 4 are installed in the gap between the conveyor platform 2 and the placement platform 22. Above each drive ring 4 are multiple drive frames 8 equidistantly distributed along a circumferential trajectory. The end of each drive frame 8 near the outer side of the conveyor platform 2 is detachably connected to a limit rod 3. When round goods are stacked on the placement platform 22, as the multiple drive frames 8 move synchronously, the multiple limit rods 3 can move synchronously closer to or away from the round goods.

[0029] After multiple limiting rods 3 move and abut against the sides of the stacked circular goods, their position on the placement platform 22 can be easily adjusted, improving the accuracy of the distribution of the circular goods and facilitating precise stacking and destabilization operations. Simultaneously, as the stacked circular goods move with the placement platform 22, swaying or shifting of the goods is prevented, maintaining their stability.

[0030] An internal gear ring 41 is fixed to the inner side of each drive ring 4, and an electric gear 42 that meshes with the internal gear ring 41 is installed on each of the conveying platforms 2. See [link / reference] Figure 5As shown. Therefore, in this utility model, the electric gear 42 provides power for the rotation of the drive ring 4, and as the electric gear 42 rotates, the drive ring 4 and the internal gear ring 41 rotate synchronously.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, in this invention, multiple linkage gears 5, evenly distributed along a circumferential trajectory, are meshed on the inner side of the internal gear ring 41. Each linkage gear 5 is connected to a second linkage gear 7 via a synchronous shaft 6 coaxially distributed with it. The synchronous shaft 6 is mounted on the lower surface of the placement platform 22. Multiple drive frames 8 located below the same placement platform 22 are meshed with multiple second linkage gears 7. Therefore, when the electric gear 42 rotates, the multiple sets of linkage gears 5 and second linkage gears 7 rotate synchronously along with the synchronous rotation of the drive ring 4 and the internal gear ring 41, thereby driving the multiple drive frames 8 and the limiting rod 3 to move synchronously.

[0032] After multiple limiting rods 3 move close to the goods, they can abut against the outer surface of the stacked circular goods. Moreover, multiple limiting rods 3 are equidistantly distributed along the circumferential trajectory of the outer surface of the circular goods, thereby comprehensively and accurately clamping the stacked circular goods, maintaining the stability of the circular goods, and improving the compatibility with the circular goods during the clamping process.

[0033] like Figure 2 As shown, in this utility model, in order to enable the limiting rod 3 to smoothly contact the round goods stacked on the placement platform 22, multiple receiving channels 24 are provided on the placement platform 22. When the drive frame 8 moves, the limiting rod 3 moves within the receiving channel 24.

[0034] Furthermore, such as Figure 5 As shown, in order to maintain the stability of the drive ring 4 during rotation, the conveying platform 2 is equipped with an annular guide rail 23, and the drive ring 4 is rotatably installed inside the annular guide rail 23.

[0035] like Figure 5 As shown, limit sliders 81 are fixed on both sides of the drive frame 8, and multiple sets of symmetrically distributed linear guides 25 are installed on the conveyor platform 2. The limit sliders 81 are slidably connected to the linear guides 25. When the drive frame 8 moves, the limit rods 3 and the limit sliders 81 move stably along the distribution direction of the linear guides 25.

[0036] Furthermore, such as Figure 4 As shown, each limiting rod 3 is equipped with a first limiting ring 31 and a second limiting ring 32 distributed from top to bottom. The first limiting ring 31 and the second limiting ring 32 abut against the upper and lower ends of the drive frame 8, respectively. The setting of the upper and lower first limiting rings 31 and second limiting rings 32 can maintain the stability of the limiting rod 3 and prevent the limiting rod 3 from slipping off the drive frame 8.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
