FIG. 1 is a flow chart of the chemical fiber filament doffing method using centralized control according to the present invention. As shown in fig. 1, the chemical fiber filament doffing method of the present invention specifically comprises:
step S1, collecting real-time parameters of chemical fiber filament production at the current moment of the winding production line, and selecting data related to the generated doffing control scheme to generate real-time working information at the current moment of the winding production line;
the winding production line comprises winding machines, a doffing robot and a temporary storage device (or a loading platform), and generally, one winding production line comprises 32-96 winding machines which are arranged in a row, and each winding machine can complete the winding (forming) operation of 12 packages (one shaft) at a time; one winding production line is provided with one to two doffing robots, and each doffing robot can doff 1-3 shafts at one time; working state sensors are arranged on the winding machine, the doffing robot and the temporary storage equipment, and real-time working states of the winding machine, the doffing robot and the temporary storage equipment, such as the current position and the loading condition of the doffing robot, the current package type, the winding start time, the number of packages to be finished and a full-package signal sent out when the winding machine is full, the current temporary storage quantity of the temporary storage equipment and other real-time parameters can be obtained through the sensors; the attribute parameters of the winding machine, the doffing robot and the temporary storage device are known, and comprise the number and the actual position of the winding machine, the type of a package wound by the winding machine, the corresponding full-winding time and tube explosion time, the normal moving speed, the maximum allowable moving speed and the maximum available acceleration of the doffing robot when the doffing robot is unloaded, half-loaded and fully loaded, and the actual position, the normal temporary storage amount and the maximum available temporary storage amount of the temporary storage device; collecting real-time parameters of all equipment, and selecting data related to the generated doffing control scheme to generate real-time working information of the winding production line at the current moment; the real-time working information comprises the number M of the winding machines to be operated, the full-winding signal sending time of the winding machines to be operated, the predicted pipe explosion time and the emergency treatment duration, wherein the winding machines to be operated refer to the ending time T of the previous doffing operation period0A winder that previously signaled a full lap but did not perform a doffing operation.

due to windingThe production line is provided with a plurality of winding machines, and the real-time parameters of each winding machine, the doffing robot and the temporary storage equipment at different moments can be different, so that the winding production line at each moment can have a specific production state. For example, at time T', there is a winder m1(winding type A Package), m2The (winding type B packages) in turn signal full package but not yet doffed during the time interval T ' - Δ T ' to T ', when the winding line has p production states, so at time T ' it is necessary to generate a doffing plan which is the doffing path in p production states and should be the optimized doffing path p ' corresponding to the highest doffing efficiency, requiring the doffing robot to perform the winding machine m according to the optimized doffing path p1、m2Performing a doffing operation; at time T' there is a winder m3(winding type C package), m4(winding type A Package), m5The (winding type A packages) send out full package signals in sequence from T ' -delta T ' to T ' and do not fall off, the winding production line has q production state, so the T ' moment needs to generate optimized falling package path q ' of falling package scheme in q production state, the falling package robot needs to perform the operation to the winding machine m according to the optimized falling package path q3、m4、m5And (5) performing a doffing operation, wherein | -T '| > or less than Δ T'. As illustrated above, when the winding line has different production states, there are different optimized doffing schemes, so that the doffing robot can achieve the highest doffing efficiency when performing the doffing operation.
