Description

Technical Field

[0001] This utility model relates to the technical field of precast concrete component production equipment, and in particular to a precast component stacking and packaging system. Background Technology

[0002] Currently, in the production of precast concrete components, for small-volume but numerous precast components, palletizing robots are mostly used to pick up the precast components and place them on pallets. Then, a roller conveyor or chain conveyor transports the pallets along with the precast components to an automatic packaging machine for packaging. This involves one robot, one pallet conveyor, and one packaging machine. Production efficiency is limited, the number of pieces of equipment and the cost are high, and the equipment occupies a significant amount of production space. When further efficiency improvements are needed, it is generally achieved by adding a new set of equipment (including a palletizing robot, pallets, pallet conveyor, and packaging machine), which not only increases equipment investment costs but also increases the production floor space required. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a prefabricated component stacking and packaging system that is simple in structure, flexible in layout, conducive to improving production efficiency, saving equipment costs and factory space.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A prefabricated component palletizing and packaging system includes a palletizing robot and a packaging machine, a conveying track for connecting the palletizing robot and the packaging machine, and at least one conveying trolley disposed on the conveying track. The conveying track is provided with an unloading station, and the conveying trolley is provided with a pallet.

[0005] As a further improvement to the above technical solution: the conveying track is a straight track, the palletizing robot is located in the middle of the conveying track, and the packing machine includes a first packing machine located at one end of the conveying track and a second packing machine located at the other end of the conveying track.

[0006] As a further improvement to the above technical solution: the conveying trolley includes a first conveying trolley located between the palletizing robot and the first packaging machine and a second conveying trolley located between the palletizing robot and the second packaging machine. The unloading station is provided between the first packaging machine and the palletizing robot, and the unloading station is also provided between the second packaging machine and the palletizing robot.

[0007] As a further improvement to the above technical solution: the conveying track is a circular track, and multiple conveying trolleys are provided on the circular track. The unloading station is located between the palletizing robot and the packing machine.

[0008] As a further improvement to the above technical solution: the conveying track includes multiple segments, and the multiple segments are connected end to end to form a rectangular track, and multiple conveying trolleys are provided on the rectangular track.

[0009] As a further improvement to the above technical solution: the palletizing robot and the packing machine are respectively set to correspond to one long side of the rectangular track, and the unloading station is set to one short side of the rectangular track.

[0010] As a further improvement to the above technical solution: the pallet is rotatably connected to the conveying trolley.

[0011] As a further improvement to the above technical solution: the tray is provided with multiple spaced support parts.

[0012] As a further improvement to the above technical solution, the tray is also equipped with a gravity sensing device.

[0013] Compared with the prior art, the advantages of this utility model are: This utility model discloses a precast component packaging system. During operation, a palletizing robot stacks precast components onto a pallet on a conveyor trolley. After stacking, the conveyor trolley moves along a conveyor track, transporting the precast components to a packaging machine. The packaging machine packages the precast components. After packaging, the conveyor trolley moves again along the conveyor track to the unloading station. Using forklifts or other equipment, the stacked and packaged precast components are unloaded from the pallet. Finally, the conveyor trolley moves along the conveyor track back to the position of the palletizing robot, ready for the next stacking of precast components. This cycle repeats, achieving efficient precast component palletizing and packaging, reducing equipment investment and the corresponding factory space and costs. Furthermore, compared to roller conveyors or chain conveyors, the use of a conveyor track combined with a palletized conveyor trolley offers a simpler structure, more flexible layout, easier installation and maintenance of the conveyor track, and lower costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1 Figure 1 , Figure 2 , Figures 5 to 7 This invention illustrates an embodiment of the prefabricated component palletizing and packaging system. The prefabricated component palletizing and packaging system of this embodiment includes a palletizing robot 1 and a packaging machine 2, as well as a conveying track 3 for connecting the palletizing robot 1 and the packaging machine 2 (preferably, the conveying track 3 adopts two parallel rows of I-beams, which have a simple structure, low cost and strong load-bearing capacity), and at least one conveying trolley 4 set on the conveying track 3. The conveying track 3 is provided with an unloading station 31, and the conveying trolley 4 is provided with a pallet 41.

[0027] In this embodiment of the prefabricated component packaging system, during operation, the palletizing robot 1 stacks prefabricated components onto the pallet 41 of the conveying trolley 4. After the prefabricated components are stacked, the conveying trolley 4 moves along the conveying track 3 to transport the prefabricated components to the packaging machine 2. The packaging machine 2 packages the prefabricated components. After packaging, the conveying trolley 4 moves again along the conveying track 3 to the unloading station 31. With the help of equipment such as forklifts, the stacked and packaged prefabricated components are unloaded from the pallet 41. Finally, the conveying trolley 4 moves along the conveying track 3 back to the position of the palletizing robot 1, ready for the next stacking of prefabricated components. This cycle can achieve efficient prefabricated component stacking and packaging, reducing the amount of equipment investment and the corresponding factory area and cost. Furthermore, compared with roller conveyor mechanisms or chain conveyor mechanisms, the use of the conveying track 3 in conjunction with the conveying trolley 4 with the pallet 41 is simpler in structure, more flexible in layout, easier to install and maintain, and lower in cost.

[0028] Furthermore, in this embodiment, the conveying track 3 is a straight track, the palletizing robot 1 is located in the middle of the conveying track 3, and the packaging machine 2 includes a first packaging machine 21 located at one end of the conveying track 3 and a second packaging machine 22 located at the other end of the conveying track 3. One palletizing robot 1 corresponds to two packaging machines 2, which is beneficial to improving production efficiency. At the same time, compared with the existing technology of adding a whole set of equipment, one palletizing robot 1 can be reduced, saving costs and reducing the factory area occupied by the palletizing robot 1.

[0029] In a preferred embodiment, the conveying trolley 4 includes a first conveying trolley 42 located between the palletizing robot 1 and the first packaging machine 21, and a second conveying trolley 43 located between the palletizing robot 1 and the second packaging machine 22. Two unloading stations 31 are also correspondingly provided, used for unloading from the first conveying trolley 42 and the second conveying trolley 43 respectively.

[0030] See Figure 1 and Figure 2During operation, the first conveyor trolley 42 moves to the location of the palletizing robot 1, which then stacks the prefabricated components onto the pallet 41 of the first conveyor trolley 42. After the prefabricated components are stacked, the first conveyor trolley 42 moves along the conveyor track 3 to the first packaging machine 21, which completes the packaging of the prefabricated components. After packaging, the first conveyor trolley 42 moves to the corresponding unloading station 31, where a forklift or other equipment transports the packaged prefabricated components away. Simultaneously with the palletizing robot 1 completing the stacking and the first conveyor trolley 42 leaving, the second conveyor trolley 43 moves to the location of the palletizing robot 1, which stacks the prefabricated components onto the second conveyor trolley 43. After stacking, the second conveyor trolley 43 moves to the second packaging machine 22 to complete the packaging. The second conveyor trolley 43 then moves to the corresponding unloading station 31, where a forklift removes the packaged prefabricated components. By staggering the palletizing times of the two conveyor trolleys 4, one palletizing robot 1 can complete the palletizing of the prefabricated components on both conveyor trolleys 4, thereby improving production efficiency.

[0031] Furthermore, in this embodiment, the pallet 41 is rotatably connected to the conveyor trolley 4 (for example, the rotating shaft of the pallet 41 is mounted on the conveyor trolley 4 via a rolling bearing assembly, and the pallet 41 and the conveyor trolley 4 can rotate relative to each other via synchronous pulleys, sprocket material strip mechanisms, or gear pairs, or the pallet 41 can be directly driven to rotate by a geared motor, hydraulic motor, etc.). Since the pallet 41 can rotate 360°, it is convenient for the baling machine 2 to thread and pack from different directions, making the structure reasonable and effective.

[0032] See details Figure 7 In this embodiment, the pallet 41 is provided with multiple spaced-apart support portions 44 (such as support blocks, top rods, etc.). The support portions 44 are used to support prefabricated components, and the gaps between the support portions 44 facilitate the insertion of the fork arms of the insert teeth, thereby enabling smooth unloading. The structure is simple and effective.

[0033] In a preferred embodiment, the pallet 41 is also equipped with a gravity sensing device (not shown in the figure, such as a gravity sensor). The gravity sensing device can be used to detect the weight of the prefabricated components on the pallet 41. When the weight reaches the set maximum value, it indicates that the palletizing is complete, the palletizing robot 1 stops palletizing, and the conveyor trolley 4 starts to move towards the packing machine 2. Conversely, after the prefabricated components are unloaded from the pallet 41 at the unloading station 31, the weight reaches the set minimum value, indicating that the unloading is complete, and the conveyor trolley 4 starts to move towards the palletizing robot 1 to start the next work cycle, further improving the reliability and automation of the system.

[0034] Example 2 Figure 3This invention illustrates another embodiment of the prefabricated component stacking and packaging system. The working principle of the prefabricated component stacking and packaging system in this embodiment is basically the same as that in Embodiment 1, except that: In this embodiment, the conveying track 3 is a circular track (preferably in the shape of a racetrack), and multiple conveying trolleys 4 are mounted on the circular track. The unloading station 31 can be located at various positions between the palletizing robot 1 and the packaging machine 2. Each conveying trolley 4 can circulate in a clockwise or counterclockwise direction, sequentially completing the palletizing-packing-unloading process, achieving continuous production on the assembly line and greatly improving production efficiency. Preferably, the conveying trolley 4 can be equipped with casters for easy movement along the circular track.

[0035] Example 3 Figure 4 This invention illustrates another embodiment of the prefabricated component stacking and packaging system. The working principle of the prefabricated component stacking and packaging system in this embodiment is basically the same as that in Embodiment 2, except that: In this embodiment, the conveying track 3 includes multiple segments, which are connected end to end to form a rectangular track. Multiple conveying trolleys 4 are mounted on the rectangular track. Preferably, the palletizing robot 1 and the packaging machine 2 are respectively positioned corresponding to one of the long sides of the rectangular track, and the unloading station 31 can be located on any of the short sides of the rectangular track. The conveying trolleys 4 can be equipped with casters for easy movement along the rectangular track.

[0036] Compared with Embodiment 2, in this embodiment, because the conveying trolley 4 makes a 90° turn, the overall length of the conveying track 3 and the factory area occupied are reduced.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
