2. the general control system 7 receives an instruction of a factory MES system 70, intelligently and quickly finishes ordered caching and reasonable cooling of the casting products 8, and then the casting products are taken out of the warehouse and shaked out, and the factory MES system 70 intelligently calculates to send the casting products 8 into a proper channel for caching and cooling through a No. 1 lifting transfer trolley 2 according to the requirement of the cooling time of the casting products 8 and the sequence time of casting the casting products 8;
3. when the casting mold products are taken out of the warehouse and shaked, the factory MES system 70 sends the casting mold products 8 to the motor-driven rail 12 at the bottom layer through the intelligent calculation of the linkage of the No. 1 lifting transfer trolley 2 and the No. 2 lifting transfer trolley 3 according to the cooling time requirement of the casting mold products 8, and then enters the shakeout process for shakeout through the shakeout transfer trolley 4;
4. after the casting mold products 8 are shaked, the sand boxes are transferred to the sand box three-dimensional warehouse, and the pouring bottom plate 9 enters a box assembling procedure for standby through the pouring bottom plate rotating trolley 5 or enters a cooling three-dimensional warehouse body 1 channel for standby through the No. 2 lifting transfer trolley 3.
The cooling stereo garage system of the invention is provided with four operation modes:
first build-only mode: in the molding and box assembling process, a defective casting mold is found, can directly enter a bottom-layer maneuvering track 12 of the cooling three-dimensional warehouse body 2 through a casting line inert roller way and a No. 1 lifting transfer trolley 2, and then enters a shakeout process through a shakeout transfer trolley;
second pour-only mode: the casting molds stored in the box-combining three-dimensional warehouse enter a casting line roller way area through intelligent calling, a casting machine casts the casting molds one by one in the direction from the bottom of a stack to the top of the stack to form a casting stack and casting mold products 8, an FRID electronic tag 91 on a casting bottom plate 9 gives unique coding information of each box of casting mold products 8, the casting mold products enter a cooling three-dimensional warehouse body 1 through a No. 1 lifting transfer trolley 2 to be sequentially cached and cooled in a channel, a factory MES system 70 gives each channel a queue according to the casting time, the sequence and the cooling time requirements of the casting mold products 8, and the intelligent calculation is carried out on which channel is required to be put so as to meet the production efficiency and the quality requirements.
As the resin sand casting mold has good heat insulation performance and the cooling time of the casting mold product 8 is long, in order to ensure the quality of the resin sand product, reasonable casting heat insulation unpacking time needs to be set, because the casting is unpacked too early and is easy to leak, the casting is not formed enough, the casting is unpacked too late, the surface hardness of the casting is reduced, and therefore the unpacking time of the resin sand casting is generally controlled within 3-5 hours.
If a casting machine is adopted to cast 12 boxes of ductile iron products, the casting weight of each box of casting products 8 is 200Kg, each bag of ductile iron is 1200Kg, 6 boxes of ductile iron products can be cast, 2400 Kg of molten iron is smelted in one furnace, and the process can be finished by 2 bags of ductile casting. Wherein the casting time of each ladle is 8min, continuous spheroidizing casting, and the total time of casting 12 boxes of ductile iron products in one furnace and 2 ladles, including spheroidizing interval transportation, is 20 min. The cooling and heat preservation time is 4h +/-20 min. When a casting machine with an FRID identifier is used for casting, the casting time information of each box of casting mold products 8 is timely transmitted to the FRID electronic tag 91 of the casting bottom plate 9, and the MES system puts the 12 boxes of casting molds into a cooling three-dimensional warehouse body 1 channel for caching and cooling according to the casting mold cooling time requirement and the casting time of the casting mold products 8, and the casting molds are taken out of the warehouse and shaked out in sequence when the cooling time is memorized.
If the cooling and heat preservation time of a certain furnace of ductile iron products is 4 hours, 6 boxes of front casting products are cached in a channel of a cooling three-dimensional warehouse, 6 boxes of next furnace of casting products are poured, the cooling and heat preservation time of the casting products is 3 hours, the pouring time interval of the two products is just 1 hour, and therefore the MES system pushes the casting products 8 poured later to the channel for caching according to the pouring time, the interval time and the heat preservation time of the two products, and the ductile iron products are convenient to take out of the warehouse and fall out of the warehouse.
Third knock-out only mode:
the casting mold products 8 stored in each channel of the cooling three-dimensional warehouse body are intelligently calculated by a factory MES system 70 according to the sand shakeout time and the sequence of the casting mold products 8, the 1# lifting transfer trolley 2 and the 2# lifting transfer trolley 3 at the two ends of the cooling three-dimensional warehouse body 1 are linked to transfer the casting mold products 8 to a motorized roller table 12 at the bottom layer, and the casting mold products enter a sand shakeout process through a sand shakeout transfer trolley 4;
the fourth mode of boxing and molding at the same time: the casting mould products 8 stored in the channel of the cooling three-dimensional warehouse body 1 enter the bottom layer maneuvering roller way 12, meanwhile, the casting moulds with the defective products can enter the bottom layer maneuvering roller way 12 of the cooling three-dimensional warehouse body 1 through the casting line inertia roller way and the No. 1 lifting transfer trolley 2, and the factory MES system 70 intelligently calculates and preferentially enters the sand falling process of the casting mould products 8 or the defective products on the maneuvering rails through the sand falling transfer trolley 4.
If the casting mold products 8 are found to be poor in spheroidization or abnormal in components in the casting process, an isolation command can be input into the MES system 70 of the factory, and the casting mold products 8 with abnormal quality can be isolated intelligently and quickly through the RFID reader 41 of the shakeout process according to the unique coding information of each casting mold product 8, and manual detection and confirmation are carried out; if the 6 boxes of second-pack poured 6 boxes of 12 boxes of ductile iron products are found to be poor in spheroidization or abnormal in composition, an isolation command can be input into a factory MES system 70, the 6 boxes of casting products 8 are automatically isolated according to the pouring sequence through an RFID reader 41 when the casting products 8 are fallen out, and the first box and the last box of pouring are manually detected and confirmed.
The four operation modes of the invention have convenient operation, strong practicability, time saving and labor saving, meet the intelligent production requirements of the resin sand casting production line, and ensure the operation efficiency of the production line and the finished product rate of castings.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
