3.6 Application Example of Packing Machine
3.6.1 Description
This chapter aims at the application of ASDA-A2 on packing machine, which is for suing the
compensation of flying shear and mark tacking. If the film has improper tension adjusting,
mechanical slips or the distance between marks is different, ASDA-A2 has the automatic
correction feature to correct the errors. Moreover, functions such as to avoid empty pack, to stop
cutting when the package is in wrong position so as to avoid damaging the mechanism, function
of initial position adjusting, to produce the adequate E-cam curve base on different width of cutter
as well as the masking function between marks all provided by ASDA-A2.
It offers a novel way for servo drive users in packing industry, including the servo system with
motion command and brings a faster and more smoothing operation. Dramatically increase the
performance and reduce the cost of design and development. Especially the function of mark
tracking, it is definitely a great tool for the application of flying shear.
3.6.2 System plan
The packing system consists of three main parts, see Figure 3.6.1. The film feeding axis is the
master axis. When it is delivering the film, it issues the pulse to command the slave axes. The
first slave axis is the cutting axis for sealing and cutting while the second one is the chain
conveyor which is used for delivering packages. The name of the first and second slave is only
for explanation in this chapter and is not named in sequence in real application. It is the typical
packing system. E-cam and motion control function of ASDA-A2 can satisfy the demand of each
main control in this framework.
