As mentioned above, the working principle of the buffer apparatus for normalizing the stored articles according to the present invention is as follows:

when the deposit mechanism 1 is in a working state, an operator reads the code of the first article to be stored through the code reading device 1-4 and feeds the code back to the control system. The control system searches whether the code is stored in the database module or not in the database module according to the received code; if the code exists in the database module, finding a placing prompt instruction corresponding to the code, and sending the placing prompt instruction to the display device 1-2 and the storing jig 1-1; if the code does not exist in the database module, the control system generates a placing prompt instruction according to the specification parameters (such as shape and size) of the article, stores the placing prompt instruction corresponding to the code and the binding relationship between the placing prompt instruction and the code into the database module so as to be directly searched when the article is stored next time, and then sends the placing prompt instruction to the display device 1-2 and the storing jig 1-1. The storage jig 1-1 adaptively adjusts the width of the article which can be allowed to be stored according to the received placing prompt instruction so that an operator can stably store the article into the storage jig 1-1; meanwhile, the display device 1-2 displays the received placing prompt instruction (the optimal placing posture); an operator places the batch of articles 4 in the storing jig 1-1 in a standardized manner from the storing inlet 1-6 according to the optimal placement posture displayed by the display device 1-2; the logging operation is completed.

When the output mechanism 2 is in a working state; the clamping mechanism extends towards the storing jig 1-1, and after the clamping mechanism extends to the place, the distance between the two clamping parts 2-1a and 2-1b is adjusted according to the placing prompt instruction, so that the batch of articles 4 stored on the jig 1-1 can be clamped at one time; then the steel pipe is contracted to the initial position in the direction far away from the storing jig 1-1; the transverse moving mechanism and the lifting platform drive the clamping device to move to a corresponding goods channel position on the external storage goods shelf 3, the clamping device extends towards the goods channel on the external storage goods shelf 3, and the batch of articles 4 are stored on the goods channel of the external storage goods shelf 3 at one time; the output operation is completed.

Therefore, by adopting the optimized structural design, the standardized storage of the articles can be realized through the optimized design of the 3D profile scanner, the adjustable width of the parts such as the storage jig 1-1 and the detection grating 1-5 and the mutual matching of the parts, and further the batch of articles 4 (a plurality of articles) can be stored on the storage shelf 3 at one time, so that the storage efficiency is improved. In addition, as shown in fig. 4, the items on the storage rack 3 are stored in a standardized manner, so that the subsequent taking out operation (taking out the items from the storage rack 3) is facilitated, if one order includes a task of taking out a plurality of items, a function of taking out a plurality of items from the storage rack 3 at one time by using the AGV 5 or the RGV can be realized, and as a whole, the storing and taking process is simplified, and the taking out efficiency is also improved.

In some preferred embodiments, as shown in fig. 3, the depositing mechanism 1 further comprises load cells 1-8 electrically connected to the control system; the weighing sensor 1-8 is arranged below the 3D scanning placement origin 1-7 stored in the jig 1-1; the weight of the single article and/or the weights of a plurality of articles stored on the jig 1-1 are fed back to the control system, the control system also stores the weights of the articles and the single article into a database module of the control system, and the database module stores the data to be used as an auxiliary parameter for subsequently checking the total weight of the batch articles 4; and the user can also consult and count the data in the future. In the present embodiment, load cells 1-8 are model LS21-18MR-1 WT. Of course, a person skilled in the art can select other types of load cells 1 to 8 according to actual requirements. Thus, after the batch articles 4 are put into the storing jig 1-1 in a standardized way by an operator, whether the quantity of the articles is correct or not can be checked by weighing the total mass of the batch articles 4; when the total weight of the batch of articles 4 is the same as the weight of the individual articles stored in the database module multiplied by the target quantity of the batch of articles 4, it indicates that the quantity of the articles placed is accurate, and the function of checking the quantity of the articles is achieved.

In the present embodiment, the detection grating 1-5 is model ESCF4810L 1I-2. Therefore, after the batch articles 4 are put into the storing jig 1-1 in a standardized manner by an operator, whether the number of the articles and the placing posture are correct or not can be checked by detecting the total length of the batch articles 4; when the total length of the batch of articles 4 is equal to the length of the single article stored in the database module multiplied by the target number of the batch of articles 4, the number of the articles placed and the placing posture are indicated to be accurate, and the functions of checking the number of the articles and the placing posture are achieved.

Preferably, the buffer device further comprises a moving chassis arranged at the bottom and used for driving the whole buffer device to move. In this embodiment, the bottom of the mobile chassis is provided with 4 universal wheels.
