Problems solved by technology

[0003] The existing technologies related to weighing and counting, 1. Manual counting, but the speed is slow, the labor intensity is high, and it is easy to fatigue and make mistakes
2. Directly weigh the total weight of the target quantity of small packages through manual weighing, divide by the standard weight of each bag, and round the result to find an integer as the total number of bags required for the target. However, due to the need for manual loading, the target is approaching The total needs to be carefully added or subtracted, which is too slow, labor-intensive and error-prone
3. The weighing method cannot be used for the target packaging number with a large quantity
4. Automatic visual inspection equipment is not only costly, but also prone to errors: one flexible package folded in half is easily mistaken for two

Embodiment 1

[0043] Embodiment 1: as figure 1 As shown, a weighing and counting method includes: it is composed of ten functional steps, and realizes repeatedly calling and recombining Sign[i] and Array[i] corresponding to N unit scales.

[0044] Each unit scale can achieve weighing, can receive unloading instructions and unload the materials on the weighing platform, and is also equipped with a feeder.

[0045] Parameter input steps: Obtain the number of effective unit scales N, the target number of packages P, the number of unit scales expected to be combined Q, 2≤Q≤(N-1), the standard weight m of a single small package, and calculate the weight of each unit scale The target packet number A, the integer part of A=P / Q after rounding.

[0046] Create and control steps of material array: Create and clear the material array Sign[N], the element Sign[i] of the material array Sign[N] corresponds to the material status of the i-th unit scale, and Sign[i]=0 represents the i-th unit scale There...

Embodiment 2

[0081] Embodiment 2: as figure 1 As shown, a weighing and counting system includes the following functional modules, which realize repeated calls and recombinations of Sign[i] and Array[i] corresponding to N unit scales.

[0082] Each unit scale can achieve weighing, can receive unloading instructions and unload the materials on the weighing platform, and is also equipped with a feeder.

[0083] Parameter input module: obtain the number of effective unit scales N, the target number of packages P, the number of unit scales expected to be combined Q (2≤Q≤(N-1)), the standard weight m of a single small package, and calculate each unit scale The target number of packets A (A=P / Q integer part after rounding).

[0084] Material array creation and control module: create and clear the material array Sign[N], the element Sign[i] of the material array Sign[N] corresponds to the status of the i-th unit scale with or without material, and Sign[i]=0 represents the i-th unit scale There i...

Abstract

A weighing and counting method is characterized by comprising the following functional steps, and repeating calling and recombining of Sign[i] and Array[i] which correspond to N unit scales are achieved. The functional steps including a parameter input step that the target package number A (the integer part of A=P / Q after rounding off) of each unit scale is calculated; a material number array establishing and controlling step; a package number array establishing and controlling step; a running controlling step that a material unstow instruction is sent to each unit and a running beginning or stopping instruction is received; a material judging and controlling step; a package-free judging and weighing and counting step that Array[i]=0, that is, the corresponding unit scales with the numberof small packages being zero on all number arrays are weighed as M, and the weight value M divides the standard weight m of each small package to obtain the number of the small packages; a package refreshing and judging step that according to the Array[i] of the weighing and counting step, if Array[i] is larger than or equal to 1, Sign[i] is equal to 1; a combination starting and summing step thatall elements of the Array[N] are added and summed; and a basic combination operation and control step that according to the serial number sequence of the unit scales, the combination of QJ elements is taken from the N elements of Array[i], and the numerical value sum of the elements corresponding to the combination is solved.

Description

technical field [0001] The application relates to the field of automatic packaging, in particular to weighing and counting packaging equipment. Background technique [0002] In the production and packaging process of food, medicine, daily chemical products, etc., it is often necessary to pack multiple small packages or small items with approximately the same weight into a large packaging box (bag, box, container) according to a certain number. [0003] The existing technologies related to weighing and counting include: 1. Counting by hand, but the speed is slow, the labor intensity is high, and it is easy to make mistakes due to fatigue. 2. Directly weigh the total weight of the target quantity of small packages through manual weighing, divide by the standard weight of each bag, and round the result to find an integer as the total number of bags required for the target. However, due to the need for manual loading, the target is approaching The total needs to be carefully ad...
