Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to a transfer device for large workpieces. Background Art

[0002] In recent years, the rise of 3D printing sand core technology has ushered in a major technological revolution in the foundry industry. This technology has significantly streamlined production processes, driven industry transformation and upgrading, and quickly become a cutting-edge technology in the foundry sector. Against this backdrop, numerous professional 3D printing equipment manufacturers have emerged, fueling industry prosperity while also intensifying market competition. To achieve a differentiated competitive advantage, manufacturers have begun to break through the size limitations of traditional equipment and develop large-scale 3D printers.

[0003] The advent of large-scale 3D printers has solved numerous challenges in industrial casting, marking a significant breakthrough for the international foundry industry. However, this new equipment also presents new challenges: the sand box of traditional 3D printers typically measures 2.5m x 1.5m, producing sand cores approximately 1m x 1m in size and weighing no more than 1 ton. Gantry robots can handle the logistical transfer of cores, including core removal, air washing, flow coating, drying, and storage. However, large-scale 3D printers can produce sand cores measuring up to 4m x 2.5m x 1.5m and weighing approximately 15 tons. This presents a dual dilemma for traditional transfer methods: first, the structural strength of large sand cores is insufficient to withstand repeated lifting; second, gantry robots suitable for large sand cores are not only expensive but also lack flexibility. Therefore, the industry urgently needs to develop a new logistics solution that can automate and flexibly transfer large sand cores. Summary of the Invention

Furthermore, setting the second running track 4 as a through-type can facilitate the transfer of the second transfer mechanism 2 between the processes on both sides of the first running track 3, thereby avoiding the problem of the first transfer mechanism 1 needing to turn around. The first transfer mechanism 1 can transfer the sand cores between the processes on both sides by performing reciprocating motion on the first running track 3, thereby achieving sand cleaning and coating of the sand cores, and improving the efficiency of logistics between processes.

[0032] As a further supplement to this embodiment, first scales extend from both ends of the second operating track 4 to facilitate docking of the second operating track 4 with the docking guide rail 5, thereby enabling the second transfer mechanism 2 to travel from the first transfer mechanism 1 along the second operating track 4 and the docking guide rail 5 to the process operation space. In this embodiment, the length of the second operating track 4 extending from the first scale is no more than 30 cm, thereby facilitating docking with the docking guide rail 5 and preventing the first transfer mechanism 1 from interfering with the surrounding environment during travel.

[0033] As a further supplement to this embodiment, the end of the docking guide rail 5 away from the second running rail 4 is in the working space area of ​​the operation process (the end of the docking guide rail 5 away from the second running rail 4 is called the end of the docking guide rail, and the end of the docking guide rail 5 docking with the second running rail 4 is called the starting end of the docking guide rail). A jacking and flipping mechanism 8 is provided in the working space area. The jacking and flipping mechanism 8 is used to carry the pallet and workpiece from the second transfer mechanism 2, and the workpiece is located in the pallet; the jacking and flipping mechanism 8 includes a column, a beam, a flipping structure 805, a base 806 and a pallet support 807, one end of the column is set on the ground, and the end of the column away from the ground is provided with the beam, and the beam and the column form a high platform U-shape.

The two first columns 801 are arranged outside the extension line of the end of the docking guide rail, and the two second columns 802 are arranged on both sides of the docking guide rail 5. The four columns form the support of the jacking and flipping device. The first beam 803 is provided on the top of the end of the first column 801 and the second column 802 on the same side of the docking guide rail 5 away from the ground, and one end of the first beam 803 is rotatably connected to the first column 801, and the other end of the first beam 803 is liftably connected to the second column 802; the second beam 804 is arranged at a position close to the first column 801 and spans between the two first beams 803, and is on the upper end surface of the first beam 803 close to the first column 801. The tray support 807 is provided on it, and the tray support 807 can prevent the tray from sliding off the first beam 803; the base 806 is set on the ground between the first column 801 and the second column 802 on the same side, close to the first column 801, and one end of the flip structure 805 is set on the base 806, and the base 806 provides support for the flip structure 805. The other end of the flip structure 805 is set on the lifting section of the second column 802 close to the first beam 803. In this embodiment, the flip structure 805 is an oil cylinder, and the second column 802 can be raised and lowered by extending and shortening the oil cylinder, thereby realizing the rotation of the first beam 803 with the first column 801 as the fulcrum, thereby realizing the tilting of the sand core. In this embodiment, in order to achieve better sand cleaning and coating effects, the tilt angle of the first beam 803 is lifted to 45°-70°, and the preferred tilt angle is 60°.

[0034] As a further supplement to this embodiment, the second column 802 includes a fixed section and a lifting section. The lifting section is inserted into the fixed section. One end of the fixed section is placed on the ground, and the other end is engaged with the lifting section. The other end of the lifting section is fixedly connected to one end of the first crossbeam 803. The flipping structure 805 lifts the first crossbeam 803 by pulling the lifting section out of the fixed section. The flipping structure 805 lowers the first crossbeam 803 by pressing the lifting section into the fixed section, thereby flipping the sand core located on the pallet. In this embodiment, the second column 802 is composed of two sections of square steel of unequal diameters, with the lifting section inserted into the fixed section.

[0035] As a further supplement to this embodiment, the lifting and flipping mechanism 8 further includes a bottom beam 808, which is connected to the base 806 and is disposed between the two upright posts perpendicular to the direction of the docking rail 5 to enhance the stability of the lifting and flipping mechanism 8.

In this embodiment, when the second transfer mechanism 2 carrying the pallet with the sand core is completely above the carrying space of the jacking and flipping mechanism 8, the first crossbeam 803 of the jacking and flipping mechanism 8 flips and lifts, causing the pallet to fall away from the upper end surface of the second vehicle body. When the distance sensor on the second transfer mechanism 2 detects that the distance between the pallet and the upper end surface of the second vehicle body reaches a specified distance, the second control component drives the second drive component based on the return information to cause the second transfer mechanism 2 to return to the first transfer mechanism 1, thereby unloading and returning to standby.

[0037] In another embodiment, the transfer method of the transfer device of the present invention has the following specific transfer process:

[0038] S01: The first control unit receives workpiece transfer task information and drives the first transfer mechanism 1 to transfer the workpiece from the previous process to the second transfer mechanism 2 above it according to the transfer task;

[0039] Specifically, in this embodiment, the first control component receives sand cleaning task information for transferring the sand core from the core-out station to the sand cleaning process. According to the sand cleaning task, the first transfer mechanism 1 moves from the standby area to the core-out station, and the lifting equipment places the sand core on the second transfer mechanism 2 provided on the first transfer mechanism 1.

[0040] S02, the first transfer mechanism 1 moves along the first running track 3 from the previous process to the entrance and exit of the next process;

[0041] Specifically, in this embodiment, the first transfer mechanism 1 runs from the core discharge station along the first operating track 3 to the entrance and exit of any idle sand cleaning station 6 in the sand cleaning area, and docks the second operating track 4 with the docking guide rail 5; in order to facilitate the docking of the two, a first transfer mechanism 1 is provided at the entrance and exit of each sand cleaning station 6, so that the first transfer mechanism 1 can be accurately docked quickly and conveniently; in addition, each of the sand cleaning areas is provided with a plurality of sand cleaning stations 6, so that each sand core can be sealed and cleaned at an independent sand cleaning station 6, avoiding mutual interference and dust pollution to the environment caused by sand cleaning. Specifically, each sand cleaning station 6 is an independent compartment isolated from other areas, and the entrance and exit are provided with closed structures such as rolling shutter doors or gates;

[0042] S03, the second control component receives the workpiece transfer task information, drives the second transfer mechanism 2 to move away from the first transfer mechanism 1 according to the transfer task, and enters the lifting and turning mechanism 8 of the working space of the next process along the second running track 4 and the connecting guide rail 5;

[0043] Specifically, in this embodiment, when the first transfer mechanism 1 arrives at the entrance and exit of the sand cleaning station 6, the in-position limit mechanism sends an in-position signal to the first control component, the first transfer mechanism 1 stops running, and at the same time sends a sand core in-position information. After receiving the sand core in-position information, the second transfer mechanism 2 transfers the sand core along the second operating track 4 and the connecting guide rail 5 to the top of the jacking and flipping mechanism 8 in the sand cleaning operation space. A sand cleaning in-position switch is provided at the end of the connecting guide rail 5. When the second transfer mechanism 2 triggers the sand cleaning in-position switch, the second transfer mechanism 2 stops running. At this time, the tray with the sand core is just completely above the jacking and flipping mechanism 8;

[0044] S04, the lifting and turning mechanism 8 lifts the pallet, so that the pallet is separated from the second transfer mechanism 2 and is seated on the lifting and turning mechanism 8;

[0045] Specifically, in this embodiment, the flip structure 805 of the lifting and flipping mechanism 8 is extended to lift the first crossbeam 803 around the first column 801. When the distance between the pallet and the second vehicle body of the second transfer mechanism 2 exceeds a specified distance, the distance sensor provided in the second transfer mechanism 2 sends a message of successful unloading.

[0046] S05, the second transfer mechanism 2 returns to the first transfer mechanism 1, completing the transfer task of the workpiece;

[0047] Specifically, in this embodiment, after receiving the unloading success information, the second control component drives the second transfer mechanism 2 to return to the first transfer mechanism 1, completing the automatic transfer of the sand core from the core discharge station to the sand cleaning station 6, and realizing the full automation of the inter-process logistics of large sand cores.

[0048] As a further supplement to this embodiment, the logistics process of the sand core from the sand cleaning process to the coating process is as follows:

[0049] S11, when the sand cores of the sand cleaning station 6 are cleaned, a coating task information is issued, and the first transfer mechanism 1 moves along the first running track 3 to the entrance and exit of the sand cleaning station 6 where the sand cores to be coated are located;

[0050] S12, after the second transfer mechanism 2 receives the coating sand core unloading information, it verifies that the second running track 4 and the connecting guide rail 5 travel to the jacking and turning mechanism 8 of the coating operation space; a number of coating rooms 7 are provided in the coating area, and the coating rooms 7 are also independent compartments that can be closed to avoid interference and pollution to other areas; in order to facilitate the docking of the first transfer mechanism 1 and to introduce the number of setting limit mechanisms in place, the sand cleaning station 6 and the coating room 7 are set correspondingly, and the two connecting guide rails 5 are on the same axis;

[0051] S13, after the second transfer mechanism 2 reaches the end of the docking guide rail 5, the flipping device of the jacking flipping mechanism 8 lifts the pallet with the sand core, so that the pallet is separated from the second transfer mechanism 2. When the distance between the pallet and the second vehicle body reaches a specified distance, the flipping device stops extending to stop lifting and flipping the first crossbeam 803 and the pallet, so that the first crossbeam 803 forms an angle of about 60 degrees with the horizontal direction, achieving the best angle for coating;

[0052] S14, the second transfer mechanism 2 returns to the first transfer mechanism 1 according to the unloading success information, completes the automatic logistics transfer of the coating task, and returns to the standby state.

[0053] As a supplement to this embodiment, before the first transfer mechanism 1 takes over the workpiece from the previous process, the first transfer mechanism 1 first moves to the pallet storage area. According to the model of the workpiece in the transfer task, the corresponding pallet is placed on the second transfer mechanism 2 by the lifting equipment, and the workpiece can be placed on the pallet for transfer.

[0054] As a supplement to this embodiment, when all the operation processes of the workpiece are completed, the first transfer mechanism 1 equipped with the second transfer mechanism 2 transfers the workpiece to the three-dimensional warehouse, and the stacking robot of the three-dimensional warehouse transfers the workpiece to the corresponding storage position of the three-dimensional warehouse, thereby realizing the full automation and unmanned logistics of the workpiece.

[0055] As a further supplement to this embodiment, a constant temperature and humidity system is provided in the stereoscopic warehouse. By adjusting the temperature and humidity in the stereoscopic warehouse, the sand cores after coating entering the stereoscopic warehouse can be efficiently dried, and it can be ensured that the stored sand cores will not lose strength due to excessive humidity in the stereoscopic warehouse, thereby ensuring that the sand cores after leaving the warehouse meet the requirements of subsequent core assembly and pouring.

[0056] By implementing the technical solution of the present invention in the molding process, fully automated and unmanned logistics of sand cores from the core discharge station to sand cleaning to coating to storage in the molding process is realized, thereby improving logistics efficiency.

[0057] The above embodiment is only a description of a typical application of the technical solution of the present invention, and reasonable expansion can be made on a reasonable basis without requiring creative work.
