Abstract
The aim of the invention is to arrange the start-up and stopping process with separate drives for weaving and shedding machines such that the necessary electrical currents or powers can be kept as low as possible and/or as regular as possible with a high degree of control and operational security. Said aim is achieved for the start-up phase, whereby the weaving machine is firstly operated at a crawling speed after a start time (t2), which can be set just before, at the same time, or just after the start time (t1) of the shedding machine, whilst the shedding machine is accelerated up to operating speed with an acceleration dependent only on the drive and the weaving machine is then accelerated sharply out of the crawling speed movement to operating speed after reaching a given position, speed, or torque value, or on reaching a time (t3). According to the invention, on stopping, the weaving machine is correspondingly sharply decelerated to a crawling speed operation in order to come to a standstill at a time (t11), which can be set to be just before, at the same time, or just after the stopping time (t12) of the shedding machine, whilst the shedding machine is braked more slowly relative to the sharp braking process for the weaving machine. In a preferred embodiment there is also the possibility of arranging the start of the shedding machine, either by presetting or by independent control of the drive system such that the working speed necessary for the operation is first achieved after the beat-up of the weaving machine and the stopping of the shedding machine is introduced before the stopping of the weaving machine (after beat-up).
Description
Technical field
The drive unit system that the present invention relates to the method for work of a kind of loom and tapping machine and be used to implement this method.
Background technology
DE 100 53 079 C1 disclose a kind of method; the starting of tapping machine is postponed the time that can predesignate or the time period that can predesignate in advance with respect to the starting of loom; and in the shutdown stage; the braking of tapping machine is slower with respect to the braking of loom; method is to predesignate a time value or time difference like this for tapping machine, makes tapping machine with respect to one corresponding period of the more late shutdown of loom.
This method is specially adapted to this tapping machine, and promptly the such shedding motion of shank or pusher jack is not mandatory and motion associated movement drive unit, but depends on that pattern can predesignate the motion of shedding motion.This method relates to for example dobby machine and jacquard.
The shortcoming of DE 100 53 079 methods that C1 provides is that loom is " suddenly " starting on sometime.Because the starting asynchronous of tapping machine and loom carries out in the method, but on two machine technology in a certain (time) but must keep synchronous regime on the point, so this start-up period is a sensitizing range.For example, on drive for mechanical loom, can there be the defective of having only starting order of utilizing or actual beginning starting process to understand.There is not operational measure (preliminary examination campaign yet; Measure) with the information of relevant loom state, particularly its degree of heat.But the latter has material impact to machine performance or power consumption in the starting exactly.
In addition, if shedding motion does not have the many transhipments of wefting insertion when starting moving, according to the invention of document DE 100 53079 C1, the space of tapping machine " soft " starting that offers the mandatory motion associated movement (for example so-called shedding cam machine) with drive unit of shedding motion is very little.
There is this adverse effect of for example warp thread napping that must avoid in this motion to warp thread.
Summary of the invention
The objective of the invention is to, design starting and stopping process under the independent control device of loom and tapping machine make it under the situation of regulation technology and operation tight security, with required electric current or power remains on the as far as possible little degree and/or evenly.
This purpose is achieved by the method for work of a kind of loom and tapping machine according to the present invention; wherein; electronic main drive of loom equipment; electronic assistant drive device of tapping machine equipment; utilize a control device that electronic main drive and electronic assistant drive device transmission signal ground are controlled in view of the above; loom and tapping machine be from shut down arriving a rotating speed of predesignating in view of the above, and loom and tapping machine are shut down by brake apparatus when breaking down.According to the present invention, tapping machine is then lighted from its starting time and is utilized an acceleration that only depends on drive unit itself to quicken in the direction of working speed, then, the rotating speed of loom from predesignating itself, when reaching position, rotating speed or the torque value predesignated or time point, start suddenly to working speed and/or in stopping process, the correspondingly unexpected on the contrary retarding braking of loom is to the rotating speed of predesignating, so that shut down on a time point of predesignating; And with respect to the at first unexpected braking procedure of loom, tapping machine is braked more slowly.
As mentioned above, loom is lighted at first from a certain starting time and is moved with the rotating speed of predesignating corresponding to the adjustment stroke motion, and can begin to start tapping machine simultaneously, perhaps even before it starts.
If the motion of actual beginning adjustment stroke, probability that on the one hand can be higher subsequently during " suddenly " acceleration from the zero defect function of drive system.On the other hand, drive system particularly obtains the particularly statement of degree of heat of loom state by the moment of torsion that needs of loom movement.It can be for example be used to constitute by adjusting regulator parameter that subsequently " suddenly " quickens and synchronous with tapping machine.
In addition, no matter equipment control device is the adjustment stroke motion or the residing stage of the starting of tapping machine of loom, all can analyze each other two motions, so as particularly to quicken for loom " suddenly " subsequently and with tapping machine coordinate these processes synchronously as far as possible.
In a kind of special scheme of the present invention, the starting of tapping machine is carried out like this, and tapping machine is carried out on first time point that beats up with the desired working speed of working at loom, has and the different rotating speed of the desired working speed of work.
If this rotating speed is lower than desired working speed, if this means the required acceleration of tapping machine also can reduce-and exactly for the reason of textile technology, the time that tapping machine starting is arranged on before the loom starting must not be arbitrarily, and this point is as there is the sort of situation of warp thread napping danger in above-mentioned shedding cam machine.
In another special projects of the present invention, under the situation that needs are shut down, the braking procedure of tapping machine was just beginning before relative beating up for the last time of shutting down with the desired working speed of working with loom.In this manner, can the time range or the rotation angle range that use for braking procedure obtain prolonging,, reach time point that tapping machine shuts down or spin angular position and be in that to reach loom must not be arbitrarily after shutting down although for the reason of textile technology.That is to say moment of torsion braking that can be less.But it should be noted that this shutdown principle can only use in the ad hoc approach of outstanding effect wefting insertion.
The present invention also realizes by the drive unit system that is used to implement said method.According to the present invention, tapping machine is dobby machine, shedding cam machine or jacquard weaving machine.
