Since the advent of the palletizer, a large number of pallets, also called logistics pallets, have emerged, which are media for converting static goods into dynamic goods, as well as a cargo carrying platform, which is also a mobile platform or ground. Even if the goods which are not flexible on the ground are loaded, the goods can be immediately moved to be flexible and mobile goods, because the goods loaded on the pallets are in a preparation state which can be shifted to move at any time, and the dynamic loading and unloading method which is composed of the pallets as basic tools is called pallet operation. The flat tray is almost a substitute name of the tray, and as long as the tray is mentioned, the flat tray is generally referred to as the flat tray, because the flat tray has the widest application range, the largest utilization number and the best universality. The flat trays are classified according to the table top: the utility model has four types of single-sided type, single-sided use type, double-sided use type and wing type; classifying according to forklift fork-in modes: a unidirectional fork type, a bidirectional fork type, a four-way fork type and the like; according to the material classification: five kinds of wooden flat pallets, steel flat pallets, plastic flat pallets, composite material flat pallets and paper pallets. No matter how the trays in the prior art are arranged, the problem of occasional unstacking in the actual operation process cannot be changed. The utility model discloses an inventor has found the buttress phenomenon of collapsing many times in many years's practical process, and the place, the mode of collapsing the buttress each time are all different, in order to thoroughly solve this problem, improve the quality of pile up neatly and the efficiency of transporting, and the inventor has carried out a large amount of analysis to prior art, has found the reason of collapsing the buttress accident to adjustment optimization has obtained the technical scheme that the invention created, the inventor discovers: the present phenomenon of pile breaking is mainly due to the fact that the density of goods is uneven, materials are eccentric, in the actual stacking process, different goods are mixed and put, in the transferring process, due to the fact that the center of gravity is instantaneously moved in the translation process, the edge part of the tray is easy to form a lever effect, the goods are separated from the stack and form the pile breaking, in order to solve the problem, the inventor carries out a lot of trial improvements according to the prior art, finally, the problems existing in the prior art can be perfectly solved through the specific combination of supporting pieces with different shapes, the rectangular base plate has a length direction and a width direction, the width direction is used as the entering direction of the forklift, a middle supporting piece is arranged on the base plate, the middle supporting piece in the text can also be called as a T-shaped supporting piece, the cross section of the T-shaped supporting piece is approximately in a T shape, and the bottom of the T-shaped supporting piece is connected to the base plate, middle part support piece is located the middle part of basal disc to middle part support piece is the symmetry axis, bilateral symmetry is provided with eccentric support piece, eccentric support piece is also called 7 shape support piece, perhaps fall "L" shape support piece, its cross section roughly is "7" font, "the vertical position of 7" font is this support piece's supporting part, when the goods is kept flat at eccentric support piece's top, because the supporting part is connected on the basal disc, its relative one side has slight decurrent deformation, this deformation has actually formed a lever: a lever taking a connecting point at the top of the 7 shape as a fulcrum; the lever formed by the goods can be respectively formed into the lever in the clockwise direction and the anticlockwise direction by arranging the symmetrical structure taking the middle supporting piece as the center, compared with the mode of forming a unified directional lever in the prior art, the possibility of goods eccentricity is greatly reduced, meanwhile, the mode of arranging the independent supporting piece at the outermost part of the base disc can form an independent fulcrum, the lever deviated to two sides forms an opposite fulcrum, the action of the lever is reduced or even eliminated, the probability of goods unstacking is greatly reduced by the trays configured by the supporting pieces in different shapes, the inventor simulates stacking by simulation software for verifying the effect created by the invention, the simulation experiment is carried out by comparing the tray of the invention with the tray in the prior art by a modeling mode, the unstacking rate of the existing tray in the experiment is about 0.08 percent, and the unstacking rate of the tray in the technical scheme of the invention is 0.005 percent, the stacking collapse rate is about 6 percent of that of the existing tray, the stacking collapse rate is greatly reduced, the originally discrete small-probability stacking collapse accidents are changed into the impossible events, the quality problem of stacking is greatly solved, and the transfer efficiency of goods is also improved; the inventors have also found another problem: in the actual use process, the phenomenon of unstacking still exists after goods are taken away, the practical analysis shows that in the pallet in the prior art, in the stacking process, the goods can move to the opposite side in the middle of the pallet, the goods can be stacked in a full tray, when the goods are taken, the fork teeth and the stacked goods are relatively changed, the goods are transferred from the transportation channel of the pallet to the goods taking channel, the change of the relative position causes the gravity center of the goods to be deviated, the reason is the most main reason causing the goods to be unstacked in the goods taking process, the scheme forms the symmetrical transportation channel and the goods taking channel by symmetrically arranging the independent supporting pieces, when in use, the fork teeth on the two sides of the middle supporting piece respectively move to the two sides to enter the goods taking channel, in the process, the positions of the fork teeth and the goods are changed, but the gravity center of the goods is not changed, the goods taking channels with the symmetrical two sides enable the stress point of the forklift and the gravity center of the stack not to be changed, and therefore the problem of stack collapse during goods taking is solved.
