Definitions
- the invention relates to a method for regulating the vacuum in a suction air system with a suction unit on one Textile machine according to the preamble of the first Claim.
- Textile machines are used for a variety of work processes Suction air needed. For example, in spinning machines a thread break the thread end with suction air from the Vacuum package and pneumatically for piecing prepared. In winding machines that have a variety of have spools arranged next to each other, is in each A catch nozzle is arranged in the thread path in order to at a possible thread break the thread end of the lower thread suck in and hold so that no drum wrap occurs. Constantly present suction air in the vicinity of the drain spool serves the suction of dirt, flue dust and fibers that occur during the process of the thread from the payout spool is created.
- the object of the present invention is the part-related Vacuum supply with regard to energy requirements and success improve.
- the invention enables automatic optimization of the Suction power of a suction unit of a textile machine, related to a game, by automatically changing one Partial start of pre-set vacuum, one subsequent evaluation of the impact on the number of each occurring error and one depending on the Confirmation or further change of the result Negative pressure.
- the suction power is reduced Dependence on the vacuum level and specific conditions of the respective lot so that the number of occurring Error increases.
- the lowering of the suction power can therefore only go as far as the machine's efficiency doesn't decreases significantly.
- the number of errors that occur respectively the tendency towards errors is the criterion whether and how far the vacuum can be reduced.
- the aim is lowest possible negative pressure with a tolerable number of mistakes. Determining the priority of the two characteristics is carried out by the operator of the machine.
- the suction power of the suction unit is like this set that a predetermined vacuum value is reached.
- Errors caused by insufficient vacuum of the basic requirement occur are drum wraps. Drum wraps are among the Errors that a machine cannot correct itself and therefore require operator intervention.
- Beat these attempts, whose The number of errors that can be specified are the errors that occurred also not automatically fixable, because the corresponding Job is shut down so that the error of an operator can be fixed.
- the vacuum is gradually changed by one predetermined amount, for example by 2 mbar.
- the The vacuum is changed by a corresponding one Setting the suction power of the suction unit, as a rule by a corresponding change in the speed of the Suction unit drive motor.
- a game is started, of which no empirical values the number of errors that occur in a specified period after the start of the game occurs as Comparison value for the number of errors occurring in subsequent periods.
- the negative pressure will lowered in the subsequent period.
- the number of then occurring error decides whether the vacuum can be lowered further or whether it is even above the entrance set level must be raised.
- the lowest determined based on the respective requirement The value of a vacuum of a period is related to the lot in the control device of the textile machine stored when in the limit for the errors during this period is exceeded. To ensure the result, the determined optimal value of the negative pressure in at least one further period of time can be checked. The storage of the optimal value for the negative pressure of a demand automatically and regardless of the observation of a Operator.
- the stored optimal value related to a lot Vacuum for a specific job can be done by anyone Restart of a comparable game automatically as Default value of the negative pressure can be set. A requirement by an operator is not necessary.
- a representation not to scale is about the time t the negative pressure p is plotted. It is here around the representation of the pressure-time diagram of a winding machine. There is a constant vacuum G1 on this winding machine the basic needs. It is the vacuum, among other things constantly touches the catch nozzles in the thread path. Of the Negative pressure for this basic need is said in the present case cannot be changed.
- Vacuum A1 for work needs. This is the negative pressure which is needed to pull the thread end from the package fetch and suck the bobbin from the bobbin.
- G1 is 45 mbar, for example Vacuum A1 for the work requirement at 60 mbar.
- the negative pressure for the Labor requirements are gradually reduced by the same amount.
- the lowering, exaggerated in the present embodiment shown should be, for example, 2 mbar.
- Registered in the diagram are three stages A11, A12 and A13 of lowering of negative pressure.
- the time period is initially Z11 the negative pressure A1, the not yet reduced negative pressure for the Work needs, each at a job, when a Event is processed.
- an error fa the vacuum increases from Basic requirement G1 on the negative pressure A1 as indicated by the Faults symbolizing lines fa is indicated.
- everyone Dash therefore represents an error that has occurred.
- the number of errors that occurred in the first period Z11 set vacuum A1 level for work needs occur is n1.
- This number n1 of errors is considered Guide value set.
- Time spans the number of errors the number of errors in the first period Z11 extended by a tolerable number t1, not be exceeded. Since the errors are Random events is the number of events in the Time Z11 occurring errors an additional number t1 tolerated by mistakes.
- the Vacuum of the work requirement to the vacuum A11 After the end of the first period Z11, the Vacuum of the work requirement to the vacuum A11. After At the end of the time period Z12, the number n1 of errors has occurred increased compared to the previous period Z11, but still lies within the tolerable number n1 + t1. Because the number of Any errors that occur are within the specification at the end of the time period Z12 a further reduction by the predetermined amount on the vacuum A12.
- the number of errors is n1, that occurred in the first period Z11 by one tolerable number a has been exceeded. The last one the reduction made did not lead to a favorable one Result and must therefore be undone.
- the vacuum A2 for the work requirement remains in the present Case constant.
- the negative pressure of the basic need in equal large steps from G2 via G21 and G22 to G23.
- the number of occurring Error fg counted is used as a guideline for the Number of errors fixed in the following Periods of time, increased by a tolerable number t2, do not may be exceeded.
- the Period Z22 the negative pressure of the basic requirement of the value G2 lowered to the value G21.
- the time period Z22 has the number of errors that occurred is a tolerable Number t2 compared to the number of errors n2 in the first Time period Z21 increased. Because the specified limit is not is exceeded, a occurs at the beginning of the time period Z23 Lowering the vacuum for the basic requirement to the value G22.
- the period Z23 has elapsed, the number of errors even decreased somewhat compared to the previous period and is around the number n2. Thereupon the negative pressure for the basic requirement to the next lower level G23 lowered.
- the vacuum is A3 for work requirements and the vacuum G3 for basic requirements set.
- Z31 determined the number of errors that occurred. Doing so distinguished between fa fa, due to events have occurred, for which the vacuum of the Labor needs must be raised.
- the fg errors are the Errors in the prevailing vacuum G3 for the basic requirement occur, especially drum wraps. The number of occurring errors must be broken down accordingly and is na and related to the vacuum for the work requirements based on the basic requirements.
- the now determined vacuum for the basic requirement G33 as well the vacuum A32 for the work requirements can each as optimal lot-related negative pressures are classified.
- the number of errors in the time period Z311 compared to the number of errors in the Period Z31 did not increase, so that in the following Period Z322 both lower the vacuum for the Basic need to the G31 level as well as lowering the Vacuum for the work requirement to level A31.
- the number of errors remains below the limit so that in the subsequent period Z333 the two negative pressures are reduced again.
- the Vacuum for desolate basic needs is reduced to level G32 lowered and the vacuum for the work requirements on the Level A32.
- the number of Error does not exceed the limit, so that at the beginning of the Period Z344 the negative pressures again by one level be reduced, namely the negative pressure for the Basic requirement on level G33 and the vacuum for the Work needs to the A33 level.
- the negative pressure for the labor requirement is in the second cycle of the Lowering back to level A32, which was already in first cycle was determined as the optimal negative pressure.
- Vacuum level G32 which was determined for the basic requirement. Due to the difference to the previous one as optimal determined vacuum value for the basic requirement can Testing, as not shown here, to be continued and the vacuum for the basic requirement again by one step be lowered to the level G33.
- the negative pressure for the Work requirements remain at the A32 level reached. Should the number of errors occur due to the Lowering the vacuum for basic needs even during the renewed lowering and not in the subsequent period increase, it can be assumed that the now reached Negative pressure for the basic requirement can be regarded as optimal can.
- the lowering cycle can be repeated if the corresponding time periods are matched to the duration of the game and the time periods are such that the number of occurring errors provide sufficient information about the Effects of lowering the vacuum can give. By repeating a lowering cycle can be checked whether the optimal value for confirms the negative pressure of a basic need or work requirement becomes.
- a pressure-time diagram is shown schematically, in which the vacuum for the working area after a predetermined period of time Z41 from level A4 by a predetermined amount to level A41 is lowered.
- the number n4 + k of the period Z42 errors fa that have occurred are greater than number n4 of errors fa, that occurred in the first period Z41, and over a limit. It can be concluded from this that the Partial vacuum set was not optimal. Out because of this, the negative pressure for labor needs increases Start of the time period Z43 by a predetermined amount on the Level A42 raised that above that at the start of the game set working pressure A4. It is intended to determine this whether the originally set negative pressure at all is optimal.
- the number decreases in the time period Z43 the errors occurred by 1 compared to the number of errors, which occurred in the first period Z41 after the start of the game is.
- the vacuum for the work needs to the level A42, the number of occurring errors.
- the subsequent period Z44 in which the vacuum is maintained at level A42, decreases the number of errors below the number of errors in the Period Z41, during the originally set Negative pressure prevailed, so that the negative pressure at level A42 can be regarded as optimal.
