Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco production, more particularly, to a formed filter rod box tracing device and method. BACKGROUND

[0002] Filter rod production is an upstream link of cigarette production, and the product quality thereof influences various indexes of downstream cigarette processes. How to improve the quality control of filter rods has always been a difficulty in filter rod forming management. The current filter rod storage system and the one-track double stacking machine scheduling system still have room for improvement in quality tracing. The system is based on RFID of the Internet of Things. When the KDF4 former outputs filter rods with high inner corner, the electronic tag reader writes the time and filter rod model into the electronic tag of the filter rod box. When 22 filter rod boxes are arranged in the conveying channel in sequence, the photoelectric tube on both sides of the conveying channel detects the relevant signals. The system associates the tray signal formed by the 22 filter rod boxes with a certain position of the high-bay warehouse (source area: specific former number, current area: specific position entering the high-bay warehouse, and tray assembly time: time when the 22 filter rod boxes enter the high-bay warehouse), and uses the high-bay crane to put them into the curing warehouse. After the filter rods are cured with glycerol, the one-track double stacking machine scheduling system determines the priority according to the number of filter rods in front of the tray unloader, adopts the first-in-first-out and tray distance, and uses the task number to automatically retrieve a certain tray. At this time, the electronic tag reader reads the information of the first filter rod box of the tray, verifies the filter rod model and storage time, and then sends it to the cigarette maker through the tray unloader and the transmitter. The transmitter has N separate channels, which correspond to the filter rod receiving assembly of the cigarette maker. After the filter rods are unloaded by the tray unloader, the empty filter rod boxes are emptied of information by the electronic tag reader again.

[0003] When the cigarette maker finds quality defects such as filter rod contact, circumference, length, and resistance, because the electronic tag reader and the filter rod tray unloader have a certain position, there are about 30 trays in the conveying channel. The transmitter needs to be paused, the task number and the storage system position number need to be converted and inferred, and the filter rod boxes on the conveying belt belong to which machine are deduced in reverse. However, it is impossible to determine the specific position of the defective filter rods in the tray, how many filter rods they are, and which machine they enter. The filter rod boxes in the channel need to be taken out one by one for manual verification, which increases the workload of quality tracing.

[0004] The existing filter rod storage system can only provide a rough range for quality tracing. It is impossible to accurately count the specific defective filter rod from which box, which cigarette maker they are sent to, and how many filter rods are sent. Position conversion between the two systems increases the difficulty and time cost of quality tracing.

[0005] Therefore, how to provide a formed filter rod box tracing device and method has become a technical problem to be solved in the field. Summary of the Invention

[0047] According to the second aspect of the present application, a forming filter rod box tracing method is provided, which comprises the forming filter rod box tracing device of any one of the embodiments, and the specific method comprises:

[0048] When starting production, the reset button is pressed, and after the manual filling of the tray unloader is completed, the tray unloader is started, the second proximity switch is at a low potential, a tray unloader material signal is generated, the tray unloader material signal triggers the one-track double-stack scheduling system to distribute the tray, the tray is transported to the tray unloader belt conveying entrance section by the overhead traveling crane, the control system obtains the information of the filter rod transmitter group, the tray, the physical position and the forming machine group according to the task list of the one-track double-stack scheduling system; the controller reads out the information of the filter rod box about to enter the tray unloader through the second electronic tag reader to obtain the position of the filter rod box in the tray; the controller obtains the number of the filter rod box to be launched in the tray and the number of the filter rod to be launched in the filter rod box to be launched through the infrared proximity switch.
