Description

Technical Field

[0001] The invention relates to the technical field of sand core transportation, and in particular to a long-distance three-dimensional aerial transportation system and method for sand cores. Background Art

[0002] Sand cores are essential consumables in the steel pipe casting process. With the development of modern industrial technology and the improvement of efficiency, the sand core transportation system plays a huge role in modern pipe casting factories. The specific steps are as follows: After the core making is completed, the sand core is placed on a tray and dried in a drying furnace before entering the three-dimensional warehouse cache. The production management system takes the corresponding sand core out of the sand core warehouse according to the production needs of the centrifuge, and sends the sand core to the corresponding forward material position of the centrifugal pipe casting machine through the automatic transportation system, and the core removal robot sends the sand core to the centrifugal pipe casting machine.

[0003] At present, the transportation equipment for sand cores usually loads the materials from the transportation device to the ground RGV trolley, and the RGV trolley transports the sand core pallet to the transportation equipment in front of the centrifuge, and then the transportation equipment transports it to the coring robot and other material positions. After the sand cores on the pallet are used, the empty pallet transportation equipment transports it to the RGV trolley, and the RGV trolley brings it back to the transportation device. The transportation device transports the empty pallet to the stacking machine, and the stacking machine stacks the empty pallets, and then transports them to the stacking machine's material picking position via the transportation device, and the stacking machine stores the stacked empty pallets in the warehouse.

[0004] This type of ground RGV trolley transportation method occupies a huge area. When the empty pallet is transported from the transport device to the RGV trolley, another empty pallet transportation line needs to be set up next to the sand core pallet transport device, which occupies a large area. In addition, the number of transport devices for transporting empty pallets will increase exponentially. After the empty pallet is returned, it will be transported to the palletizer for stacking through a series of transport devices, and then the stacked empty pallets will be stored in the warehouse by the transport device. During the entire transportation process, not only does the various transport equipment occupy a huge area, affecting the layout of other equipment, but the large number of transport equipment increases the space occupied by the factory and significantly increases the investment cost.

[0026] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs.

[0027] Example 1

[0028] like Figure 1 , Figure 2 As shown, this embodiment proposes a long-distance aerial stereoscopic transportation system for sand cores, characterized in that it includes: a stereoscopic warehouse 14, a transportation device and a conveying device; the stereoscopic warehouse 14 is provided with a pallet recovery position 5 and a sand core out-of-warehouse position 6; the transportation device includes a long beam 15 and a conveyor, one end of the long beam 15 is located on one side of the stereoscopic warehouse 14, the conveyor moves along the length direction of the long beam 15 and docks with the pallet recovery position 5 and the sand core out-of-warehouse position 6 of the stereoscopic warehouse 14; the conveying device has multiple and all located at the other end of the long beam 15, including a conveyor, the conveyor is a double-layer chain conveyor 10, and elevators are provided at the head and tail ends of the conveyor, the head end elevator 9 is docked with the conveyor, and the end elevator 11 is docked with the coring robot 12.

[0029] The pallet recovery position 5 and the core outgoing position 6 of the stereoscopic warehouse 14 are used for pallet recovery and removal of full core pallets 17 respectively. The long beam 15 is fixed to the workshop column by a bracket. The stereoscopic warehouse 14 is located at one end of the long beam 15. The conveyor drives the wheel group on the long beam 15 through the motor, and is responsible for long-distance transportation of full core pallets 17 and empty pallets 16 between the stereoscopic warehouse 14 and the conveying device. The conveying device is arranged at the other end of the long beam 15, and specifically includes a double-layer chain conveyor 10, such as Figure 4 As shown, the upper layer is used to transport full sand core pallets 17, and the lower layer is used to transport empty pallets 16. The two ends of the double-layer chain conveyor 10 are respectively arranged with a head end elevator 9 and a terminal elevator 11. The head end elevator 9 is docked with the conveyor and is responsible for receiving the full sand core pallet 17; the terminal elevator 11 is docked with the coring manipulator 12 to complete the final unloading of the sand cores on the full sand core pallet 17.

[0030] The conveyor and the conveying device can efficiently transport the full sand core pallet 17 from the stereoscopic warehouse 14 to the corresponding coring robot 12, and reasonably allocate the transportation paths of the empty pallet 16 and the full pallet through the double-layer chain conveyor 10. The full sand core pallet 17 can be directly transported out of the warehouse, and the empty pallet 16 can be automatically stacked and the stacked empty pallet 16 group can be put into the warehouse during the return process of the conveyor, which greatly improves the transportation efficiency and reduces the floor space.

[0031] The pallet recovery position 5 and the sand core outbound position 6 are set at the set height of the stereoscopic warehouse 14, which can be the top or the middle part, in order to avoid other equipment or materials in the workshop. Among them, the pallet recovery position 5 is set to one, and the sand core outbound position 6 is set to two, and the two sand core outbound positions 6 are set on the same side of the pallet recovery position 5. Optimize the recovery and outbound efficiency of the pallet to ensure that when the full sand core pallet 17 is taken out, the conveyor can complete the material receiving and transportation actions in the shortest time, avoiding the inefficiency caused by the unreasonable placement of the pallet recovery and sand core outbound position 6.

[0032] like Figure 2 , Figure 3 As shown, one of the pallet recovery positions 5 and two of the sand core outbound positions 6 are three chain conveyors, each of which can work independently and perform precise operations according to the needs of the pallet. The chain conveyor at the pallet recovery position 5 is responsible for the recovery of empty pallets 16, while the chain conveyor at the sand core outbound position 6 is responsible for delivering full sand core pallets 17 to the conveyor receiving area, effectively improving transportation efficiency.

[0033] The conveyor is a double-station aerial lift conveyor 8, each station is provided with a set of telescopic forks, and each set of telescopic forks operates independently. The double-station aerial lift conveyor 8 is driven by a motor to lift the lifting platform. The lifting platform of the double-station aerial lift conveyor 8 includes two independently working stations, namely, station 1# and station 2#. The two stations are respectively composed of two sets of telescopic fork components, each set of telescopic forks is driven and controlled by a motor alone, and the telescopic fork components of the two stations are independently operated.

[0034] The independence of the two sets of telescopic forks enables each workstation to complete its task independently without waiting for the operation of other workstations, thereby greatly improving transportation efficiency. The independently operated telescopic forks enable independent transportation of full sand core pallets 17 and empty pallets 16, reducing unnecessary waiting time and improving production efficiency.

[0035] The three-dimensional warehouse 14 is provided with a pallet dismantling machine 4, and a stacker 13 is also provided between the three-dimensional warehouses 14. The pallet dismantling machine 4 is placed at the first material level at the end of the first layer at the bottom of the three-dimensional warehouse 14, and the pallet dismantling machine 4 is opposite to the pallet recovery position 5, and is arranged up and down with the chain conveyor in space. The reasonable layout of the pallet dismantling machine 4 and the pallet recovery position 5 improves the processing efficiency of the pallet, which not only saves space, but also improves the storage and management efficiency of the empty pallets 16.

[0036] The three-dimensional transport system is also provided with a transplanter 2 and a single-layer conveyor 1. The end of the transplanter 2 is connected to the single-layer conveyor 1. The other end of the chain conveyor is arranged crosswise with the transplanter 2, which effectively avoids interference during the transport process and ensures a smooth operation sequence. The single-layer conveyor 1 is a fixed-path transport device that realizes the conversion of multiple transport paths.

[0037] A lifting conveyor 3 is provided between the transplanter 2 and the tray dismantling machine 4. The lifting conveyor 3 has an automatic lifting function, and can adjust the height according to the needs of the tray to ensure that the tray can smoothly pass through the transmission path between the various devices.

[0038] The transport system is suitable for various pallet storage types of goods. According to the different sizes and usage frequencies of the goods, the number of stations of the double-station aerial lifting transporter 8 can be adjusted.

[0039] According to the different sizes of goods, the transport distance and the requirements of the material picking and feeding height, the transport distance and the lifting height of the double-station aerial lifting conveyor 8 and the number of conveying devices can be increased or reduced.

[0040] According to the actual production rhythm and layout, the positions of the pallet discharge position and the pallet recovery position 5 in the stereoscopic warehouse 14 can be adjusted, the length of the conveying device can be increased or shortened, and the number of conveying devices can be increased or decreased.

[0041] According to actual production needs, multiple coring robots 12 can be placed according to the number and location of centrifuges, and multiple corresponding conveying devices.

[0042] In summary, this long-distance aerial stereoscopic sand core transportation system saves ground space, does not affect the layout of other ground equipment, simplifies the transportation and production links, reduces the number of related equipment, greatly improves production efficiency, and reduces investment costs.

[0043] Example 2

[0044] This embodiment provides a method for transporting a sand core long-distance aerial stereoscopic transport system as described in Embodiment 1, comprising:

[0045] When the sand core is out of the warehouse, the stacker 13 places the full sand core pallet 17 on the chain conveyor of the sand core outgoing warehouse position 6, and the double-station aerial lifting conveyor 8 goes to the sand core outgoing warehouse position 6 to wait for material transportation. The 1# station and 2# station of the double-station aerial lifting conveyor 8 correspond to the two sand core outgoing warehouse positions 6 respectively.

[0046] The forks of the double-station aerial lift conveyor 8 are extended independently to complete the material picking action. After picking up the materials, the forks are retracted to take the two full sand core pallets 17 to the loading platform of the double-station aerial lift conveyor 8 and transport them to the corresponding conveying device corresponding to the end of the centrifuge front core removal manipulator 12. The forks of the double-station aerial lift conveyor 8 are extended to place the full sand core pallet 17 on the head end elevator 9 of the conveying device. At this time, the head end elevator 9 is in a high position, and the full sand core pallet 17 is then transported to the end elevator 11 at the position of the core removal manipulator 12 via the upper conveying chain of the double-layer chain conveyor 10, and the core removal manipulator 12 takes away the sand core. At this time, the end elevator 11 is in a high position.

[0047] When the sand cores on the full sand core pallet 17 are used up, the end lift 11 descends to the low position with the empty pallet 16, and the empty pallet 16 is then transported to the head end lift 9 of the conveying device via the lower transport chain of the double-layer chain conveyor 10. After the head end lift 9 receives the empty pallet 16 at the low position, it rises to the highest position and waits for the double-station aerial lift conveyor 8 to take away the empty pallet 16 in the process of returning to the sand core outbound storage position 6 to retrieve materials. After the double-station aerial lift conveyor 8 takes away the empty pallet 16 of the conveying device, when it encounters the empty pallet 16 of the next conveying device in the process of returning to the sand core outbound storage position 6 to retrieve materials, it can place the next empty pallet 16 on the previous empty pallet 16 to complete the stacking of the empty pallets 16. The double-station aerial lift conveyor 8 brings the stacked empty pallet 16 group back to the pallet recovery position 5 of the stereoscopic warehouse 14. The stacker 13 takes away the stacked empty pallet 16 group and stores them in the warehouse.

[0048] This transportation method fully utilizes the advantages of the aerial stereoscopic transportation system, and realizes the stacking of the empty pallets 16 by precisely controlling the lifting and lowering of the double-station aerial lifting conveyor 8. When the double-station aerial lifting conveyor 8 returns to the stereoscopic warehouse 14 to pick up materials, the return transportation of the empty pallets 16 is completed at the same time. The management efficiency of the pallets is greatly improved, the transportation process is simplified, and the number of equipment and costs are reduced.

[0049] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
