Technical Field
The invention relates to the technical field of assembly line detection, in particular to a device and a method for detecting and supplementing a material bag.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The continuous assembly line when the face cake of barreled instant noodles is fried and barreled, because the trouble of throwing the chartered plane, or material package braid supply trouble, can take place the material package and put in and pause and lead to the condition that lacks the material package in the face bucket when the material package is put in. At present, manufacturers arrange 6-8 persons on a production line, check the condition that flour buckets lack seasoning bags along the production line and manually fill the seasoning bags. Since the line speed is 380-500 barrels/min, the operators need high concentration of spirit and vision, check whether there is a shortage of seasoning bags in 10 barrels flowing through about 1.5 seconds, and quickly and manually supplement the feeding when the shortage is found. If the bag throwing machine has scattered faults, the manual inspection and supplement mode can prevent defective products lacking seasoning bags from being sealed and packaged; if the equipment failure time is longer (more than 3 seconds), a large quantity of continuous seasoning bags are in short supply, and the operator can find that the seasoning bags are not delivered in time. (for example, 20 continuous shots in 3 seconds or 100 continuous shots in 15 seconds) the production line is stopped urgently, and the fried flour cake discharge production line is abandoned until the failure of the bread throwing machine is relieved, so that the waste of the flour cake is 380-.
In the existing detection method, an absolute metering mode for detecting the total amount of the product is adopted, and the detection precision and the method can not effectively identify the barreled noodles lacking the seasoning packet because the allowable deviation (15 g/barrel) of the weight (3-10 g/packet) of the seasoning packet is smaller than the allowable deviation (15 g/barrel) of the weight (130-. In order to ensure the quality of products leaving the factory, the weight of the flour cakes is often controlled to be larger in the production process control, and the difficulty of judging whether the seasoning bags are lacked by the weight is increased.

Such solutions are not considered to be known to the person skilled in the art merely because they have been set forth in the background section of the invention.
