In step S2, the characteristic information and dip-coating information of the sand core product output at the station of the core making machine 14 are the same as the information contained in the identification code on the empty tray, and only one kind of sand core is produced at one station of the core making machine, and the first sorting robot 11 loads the sand core output at the station of the core making machine into the empty tray with the identification code, so that the stacking operation of the next procedure is facilitated.
In the step S3, the first disc stacking machine 12 stacks the single-layer trays with the same identification code into at least two layers, so that the placing area of sand cores is reduced, the whole stack of trays is placed on the first RGV6 for forward conveying, sand cores are not required to be placed on a net cage or a special trolley and then conveyed, the use of the net cage or the special trolley is eliminated, and the technical problem that the net cage or the special trolley occupies a large area of the ground surface is solved; in the embodiment of the application, the tray sand core can be stacked into 2 layers, 3 layers, 4 layers, 5 layers and 6 layers; the sand cores with the same product characteristic information and the same dip-coating information are stacked into a whole stack and then conveyed to a next procedure, so that the mixing risk brought by mixing and conveying of various sand cores is solved, and meanwhile, the conveying efficiency is improved.
In step S4, the error-proofing detecting machine 21 identifies the identification code on each stack of trays, prevents the sand cores of different product characteristic information and different dip-coating information from being mixed in the sand cores of the stacked trays, and causes production errors in the subsequent process, if the identification codes of the stacked trays are different, the stacked trays are taken out as abnormal pieces, and the abnormal pieces are returned to step S1, and the operations of steps S1 to S4 are repeated.
In step S5, dip-coating information is identified by the code scanning sorter 22, so that dip-coated sand cores are conveniently and accurately sent to the surface drying furnace 23 for drying, the non-dip-coated sand cores do not need to be dried, energy waste and equipment loss are avoided, the non-dip-coated sand cores can be directly sent to the production station 54 according to production requirements, and production efficiency is improved.
In step S6, the second tray remover 51 is used to separate the whole stack of trays into single trays, so that compared with manual tray removal, the production efficiency is improved, and necessary conditions are provided for full-automatic production.
In step S7, the second sorting robot 53 takes out the sand cores on the trays, sends the sand cores to the corresponding production station 54, and places the empty trays with the same identification code on the second tray stacking machine 52, thereby improving the production efficiency and providing necessary conditions for full-automatic production.
In step S8, the second disc stacking machine 52 stacks the empty trays into at least two layers, and the specific stacking layers are preferably the same as the stacking layers when the sand cores are placed, so that the empty trays can be conveniently and efficiently returned to the disc loading unit, and the production efficiency is improved.
In step S9, the tray overturning machine 55 is used for overturning and cleaning the scattered sand on the whole empty trays, so that the problems of residual scattered sand on the trays and low scattered sand cleaning efficiency are solved.
In step S10, the empty tray is returned and the tray is removed, in preparation for continuous production.
