[0046] The present embodiment provides a riser feeding system and a casting production line. The casting production line includes a molding system (not shown) and the riser feeding system provided in the present embodiment. The riser feeding system is arranged upstream of the molding system and is configured to feed the riser material 10 to the next station. In the present embodiment, the next station is the mold plate of the molding system, which is a template for making a casting, and is used to limit the position and shape of the sand mold to form the desired casting. In the present embodiment, the molding system is specifically a static pressure molding system, which can use airflow to pre-compact the molding sand, and then compact the molding sand on the back of the sand mold to form a casting. Through the riser feeding system provided in the present embodiment, the automatic feeding of the riser material required by the molding system can be achieved, which is conducive to improving manufacturing efficiency and saving manual labor.

[0047] Figure 1 The schematic diagram of the riser feeding system provided by the embodiment of the utility model is shown. Figure 1 The riser feeding system provided in this embodiment includes a feeding mechanism 100, a transfer storage mechanism 200, a transfer mechanism 300, a buffer mechanism 400 and a feeding mechanism 500. The feeding mechanism 100 can move the supporting member 20 supporting the riser material 10. The transfer storage mechanism 200 can store the riser material 10. The transfer mechanism 300 is arranged between the feeding mechanism 100 and the transfer storage mechanism 200. The buffer mechanism 400 is arranged on one side of the transfer mechanism 300 and can store the supporting member 20. The feeding mechanism 500 is arranged between the transfer storage mechanism 200 and the molding system.

[0048] That is to say, the feeding mechanism 100 can move the riser material 10 and the supporting member 20 from the transport trolley to the grabbing range of the transfer mechanism 300. The transfer mechanism 300 can grab the riser material 10 on the feeding mechanism 100 according to the type and place it in the transfer storage mechanism 200 for temporary storage; the transfer mechanism 300 can also grab the supporting member 20 on the feeding mechanism 100 and place it in the cache mechanism 400 for temporary storage. In other words, the transfer mechanism 300 can unload the empty supporting member 20 and continue to transfer the riser material 10. The loading mechanism 500 can load the riser material 10 on the transfer storage mechanism 200 to the molding system. The transfer storage mechanism 200 can store the riser material 10 within the grabbing range of the loading mechanism 500, so that the loading mechanism 500 can continue to transfer the riser material 10 to the downstream molding system for use. The buffer mechanism 400 provides a placement position for the empty supporting member 20. When all the riser materials 10 on the supporting member 20 are transferred by the transfer mechanism 300, the supporting member 20 can release the position on the feeding mechanism 100, further improving the continuity of the feeding process of the riser material 10, speeding up the feeding rhythm, and further speeding up the casting manufacturing rhythm.

[0049] Continue to refer to Figure 1 In order to improve the safety of the riser feeding system and prevent accidental injury to operators, the riser feeding system also includes a safety fence 600. The transfer storage mechanism 200, the transfer mechanism 300, the cache mechanism 400 and the feeding mechanism 500 are all located in the safety fence 600, and the feeding mechanism 100 can extend into the range of the safety fence 600 to dock with the transfer mechanism 300. The safety fence 600 is provided with a first door body 610 at a position opposite to the cache mechanism 400. When the first door body 610 is opened, the cache mechanism 400 carrying the supporting member 20 can be moved out of the safety fence 600 to transfer the supporting member 20, and the empty cache mechanism 400 can enter the range of the safety fence 600 from the first door body 610 to receive the supporting member 20.

[0050] Specifically, the cache mechanism 400 includes a plurality of storage tables that are parallel to each other and spaced apart in the vertical direction, and the plurality of storage tables can store the supporting member 20 to increase the capacity. In this embodiment, the cache mechanism 400 can be a multi-layer flatbed vehicle to facilitate the transfer of the operator.

[0051] Specifically, the safety fence 600 is further provided with a second door body 620. The second door body 620 is movably arranged at the walking passage of the safety fence 600. When it is necessary to inspect each mechanism in the safety fence 600, the second door body 620 is opened for the operator to enter.

[0052] More specifically, the riser feeding system further includes a controller 700. The controller 700 is disposed outside the safety fence 600. The feeding mechanism 100, the transfer mechanism 300 and the feeding mechanism 500 are respectively connected to the controller 700 for communication, and the controller 700 can be used to control the actions of the feeding mechanism 100, the transfer mechanism 300 and the feeding mechanism 500. The controller 700 can specifically be a single chip microcomputer, and its control method and principle are not described in detail in this embodiment.

[0053] Continue to refer to Figure 1 In this embodiment, the feeding mechanism 100 includes a transport track 110, a portion of which is located outside the safety fence 600, and another portion of which extends into the safety fence 600. The transport track 110 can transport the riser material 10 and the supporting member 20 to the grabbing range of the transfer mechanism 300.

[0054] Specifically, the feeding mechanism 100 further includes a material in-place sensing device, which is specifically arranged at the end of the transport track 110 near the transfer mechanism 300. The material in-place sensing device is communicatively connected to the controller 700. When the material in-place sensing device senses that the riser material 10 and the supporting member 20 are transported in place, the controller 700 controls the transfer mechanism 300 to move and grab the riser material 10.

[0055] Figure 2 A partial structural diagram of the transfer mechanism provided by the embodiment of the utility model is shown, referring to Figure 1 and Figure 2 The transfer mechanism 300 includes a first mechanical arm 310 and a suction device 320.

And taking the riser material 10 by vacuum adsorption can effectively avoid the problem of mechanical clamps causing damage to the riser material 10.

[0057] More specifically, the transfer mechanism 300 includes a visual recognition device 330. The visual recognition device 330 is disposed on the first robot arm 310, located on the side of the adsorption device 320, and can identify and distinguish the various riser materials 10 on the feeding mechanism 100. That is to say, in the controller 700, the positions of the various riser materials 10 placed in disorder on the feeding mechanism 100 are identified according to the types of target products of the downstream molding system, and the types of riser materials 10 can be distinguished. After the visual recognition device 330 accurately locates the required target type, the adsorption device 320 will pick it up. The visual recognition device 330 is a prior art, and its structure and principle will not be described in detail in this embodiment.
