The invention relates to the field of cotton swab machines, particularly to fetching synchronization device and method of a cotton swab machine. The fetching synchronization method of the cotton swab machine of the invention is characterized by comprising the following steps of: firstly controlling the speeds of a cotton swab conveying chain and a transverse mechanical arm of the cotton swab machine, driving the cotton swab conveying chain by an asynchronous motor, meanwhile, regulating the speed by a frequency converter; secondly, constructing RS-485 communication between a PLC and the frequency converter, reading the present output frequency of the frequency converter in real time; after a certain computation, outputting the corresponding frequency by the PLC to drive an AC server and a server motor, enabling the transverse mechanical arm following the cotton swab conveying chain to precisely and synchronously shift at the same speed, and realizing the fetching synchronization. The speeds of the transverse mechanical arm and the cotton swab conveying chain of the invention are precise and synchronous, so that the occurrence of the production defect is avoided; the production efficiency is improved and the production cost is saved.
Description
technical field [0001] The invention relates to the field of cotton swab machine devices, in particular to a material reclaiming synchronization device and method for a cotton swab machine. Background technique [0002] At present, the reclaiming device of the cotton swab machine is basically driven by a cylinder, that is, a short-stroke cylinder is activated when the material is reclaimed, and a long-stroke cylinder is replaced at a high speed after the reclaiming is completed, so as to realize the rapid lateral movement of the manipulator arm and send the cotton swab to the packaging. The pushing speed of the two cylinders approximates the translation speed of the cotton swab conveyor chain, so as to achieve the synchronization of reclaiming and feeding. However, due to the uncontrollability of the cylinder speed, it can only be approximately synchronous but not actually synchronous, and the synchronization error can reach more than 1mm, which will inevitably cause failure...
