The weight of the plate is about 150Kg-200Kg after framing and packaging, which is generally in the packaging and unloading process, and a great deal of manpower is required to be consumed for conveying the plate from the blanking device to the transfer trolley, so that the labor intensity is high, and fatigue is easy to generate. Because the panel can leave the rivet at the wood frame in-process, very there is the risk of being scratched by the rivet when the great panel of manual handling weight, by the panel smash. In the manual plate carrying process, the plate is easy to break and bruise due to the artificial factors, and unnecessary loss is caused.

Besides the problems, the biggest problem of the manual blanking mode is that the blanking efficiency is low, the roller height of the plate packing workbench is about 950mm, the material receiving plane height of the transfer trolley is about 350mm, at least 60 s/time is needed for manually conveying the plate from the packing workbench to the transfer trolley, the time needed for moving the plate from the packing workbench to the transfer trolley is reduced, and the problem that needs to be solved in the industry is how to improve the plate blanking efficiency is solved urgently.

One end of the second bracket 3 is provided with a plurality of baffles 31, the baffles 31 are arranged at intervals along the third direction Z, and gaps 32 are formed between the adjacent baffles 31; when the conveying surface of the first conveying mechanism 2 and the conveying surface of the second conveying mechanism 4 form a certain angle, the baffle 31 is abutted against the base 81, and the rectangular tube 84 is positioned in the gap 32 when viewed along the first direction X. In some embodiments, referring to fig. 2, 4 and 5, when the second bracket 3 is turned over, the baffle 31 just falls between two adjacent rectangular tubes 84 and the bottom of the baffle 31 abuts against the base 81, and the thickness of the baffle 31 needs to be less than or equal to the maximum thickness of the rectangular tubes 84, which means that the plate 66 is directly turned over from being supported by the baffle 31 to being supported by the rectangular tubes 84, i.e. the receiving mechanism 8, after being turned over, so that the risk of excessive displacement of the plate 66 in the second direction Y due to the height difference between the receiving mechanism 8 and the baffle 31 turned over with the second bracket 3 is substantially eliminated.

The pushing mechanism 6 includes a base 68; a third bracket 64, the third bracket 64 being slidably coupled to the base 68 along the first direction X; the plate body 66 is arranged on the third bracket 64, and the plate body 66 is used for pushing the plate a to the receiving mechanism 8; the screw rod 62 extends along a first direction X and is rotatably arranged on the base 68; the screw nut 63 is in threaded connection with the screw 62 and is connected with the third bracket 64; the first driving member 61 is disposed on the base 68 and is used for driving the screw 62 to rotate.

The second driving member 65 is disposed on the third bracket 64 and connected to the plate 66, and is used for driving the plate 66 to move along the first direction X relative to the third bracket 64 so as to separate the plate a from the baffle 31. Referring to fig. 2 and 3, in some embodiments, the second driving member 65 is a piston cylinder, which may be a cylinder, an oil cylinder, or the like, a piston rod of the piston cylinder is connected to the plate 66, and the piston rod stretches and contracts to drive the plate 66 to reciprocate along the first direction X. When the third bracket 64 moves to a position where the plate body 66 is attached to the left side of the plate a, the piston rod stretches to drive the plate body 66 to move to the right, and as the plate a is generally heavy and has relatively large separation difficulty with the baffle plate 31, the second driving piece 65 can play a certain role in boosting to push the plate a away from the plane of the baffle plate 31, so that the plate a can enter the receiving mechanism 8 more easily and is contacted with the roll shaft 85 of the receiving mechanism 8, and then the first driving piece 61 drives the third bracket 64 to move to drive the plate a, the third bracket 64 and the second driving piece 65 to move integrally to continuously push the plate a.

Referring to fig. 1-5, according to some embodiments of the present application, a plate material a blanking device is provided, when a plate material a enters the plate material a blanking device after being conveyed from a packaging workbench to a first conveying mechanism 2, the first conveying mechanism 2 continues to convey the plate material a, when the plate material a is conveyed onto a second conveying mechanism 4 and is abutted against a baffle 31 (whether the plate material a is abutted against the baffle 31 or not can be judged by a contact sensor), a detecting unit detects the thickness of the plate material a, meanwhile, a second bracket 3 turns over 90 degrees, the plate material a is in a lying state again and is changed into a vertical state, meanwhile, the baffle 31 is inserted into a gap 32, and a plate body 66 is supported by a rectangular tube 84 of a material receiving mechanism 8. At this time, the pushing mechanism 6 pushes the plates a for a predetermined distance along the first direction X, and since the position of the second support 3 after being turned over is known, the position of the receiving mechanism 8 is fixed, and the predetermined distance pushed by a single plate a can be calculated based on the thickness of the plate a, that is, the pushing distance of each plate a is different due to the different discharging sequence and thickness of each plate a, so that each receiving mechanism 8 can receive as many plates a as possible, and the production efficiency is improved. Through field statistics, by adopting the plate body 66 blanking device of the embodiment, the blanking efficiency of the plate body 66 is improved by about 50%, and the blanking time is reduced to 30 s/time compared with 60 s/time in a manual blanking mode.
