Weighing and counting method and device

Abstract

The invention discloses a weighing and counting method and device. The method comprises the following steps that: on a weighing instrument, parameters are set; the weighing instrument marks current total weight on a weighing platform as total weight T before loading, and a total number N on the weighing platform is marked as zero; a pile division mechanism continuously collects a small pile of products from a production conveyor belt, and moves the small pile of products to the weighing platform, and the weighing instrument takes a stabilized weighing value as current total weight G, wherein the amount of one piece of material collection time t length of the small pile of products is small than or equal to SM; the weighing instruction calculates (G-T) / m, and M is accumulated into the totalnumber N; the weighing instruction carries out judgment; and the weighing instruction outputs a warning instruction. The weighing and counting device uses the weighing platform and the weighing instruction to form weighing instrument, the pile division mechanism is electrically connected with the weighing instruction, bears a plurality of products unloaded from the production conveyor belt in certain time, and is controlled by the weighing instruction to convey the plurality of borne products to the weighing platform.

Description

technical field [0001] The invention relates to the field of weighing and counting, in particular to a weighing and counting method and device for standard weight products. Background technique [0002] Packaging products of solid bulk materials such as food, medicine, health care, daily chemical products, hardware, etc., packaging products filled with liquid, ointment, etc., especially soft bag packaging products, because the packaging machine often needs to continue the packaging material or replace the packaging Materials need to be debugged and packaged for trial production. In normal production, there are often empty packages or non-standard packages that need to be removed by the operator. It is impossible to count and count through the packaging machine. Counting and statistics will be carried out in the following process. Due to the unsmooth cutting of the packaging material when the material is unloaded and sealed by a single multi-row packaging machine, or when th...

Problems solved by technology

[0007] It can be seen that the existing weighing and counting technology represented by the above-mentioned documents has the following disadvantages: because it needs to command the counting sensor 3 to make the baffle plate 9 vertically fall when the number of products on the weighing platform reaches the number that can be distinguished, from its attached figure 1 It can be seen that the essence is that the conveyor chain does not stop, but only prevents the steel rods on the conveyor chain from moving (there is serious relative friction between the steel rods and the conveyor chain), thereby preventing the conveyor chain 1 from continuing to feed the material to the blanking chute 4. For flexible packaging, This stop motion can seriously damage packing; Also, baffle plate 9 falls vertically, can not have damage to this hard object of steel bar, but can damage conveying chain, just for flexible packages such as bagged milk, medicine bag, rice bag, salt bag Not suitable, let alone the situation where products are piled up on the continuous production conveyor belt

The material receiving equipment or material receiving operators downstream of the weighing platform frequently repeat actions, resulting in low efficiency and high labor intensity

For the high-speed continuously moving production conveyor belt, if the standard products are scattered or piled up on it at irregular intervals, because the weighing device needs the object to be weighed to stay on the weighing platform for a period of time before it can be accurately weighed, and the continuously moving high-speed production conveyor belt Random falling, unable to meet the weighing time of the products on the weighing platform of the weighing device, the weighing device will not be able to give an accurate quantity

Obviously, this existing weighing and counting method is not suitable for irregular scattering or mutual accumulation of products on the high-speed production conveyor belt
