Description
Technical field
The present invention relates to a kind of method moved of moveable element for making injection machine and a kind of injection machine.
Background technology
Here, moveable element can be understood as the various different elements of injection machine, wherein limit and be only that, movable
Actuation gear is had to be applied on this moveable element immediately after part motion.In the case of should not be construed as limiting, can transport
Dynamic component can be had the movable mold clamp board of the lockable mechanism as actuation gear or have as effect machine
The turntable of movable mold clamp board of structure or mobile station.Actuation gear can be especially any being suitable to and moveable element shape
Become force closure or the sealed mechanism of shape.
The first example by movable mold clamp board illustrates to the present invention and its advantage below, this is because should
Example is the example that can be particularly simply introduced.But same elaboration be also applied for each other thinkable by being molded
What the moveable element of machine was constituted together with actuation gear combines.
Unrelated with the structure of the closing unit of injection machine, the closing course of closing unit mainly executes three job steps
Suddenly.First, movable mold clamp board moves in lock position, and then in this lock position, movable mold clamp board is locked out
Mechanism's locking.Then, by mostly with hydraulic pressure or the pressure mechanism that electrically constituted produces the pressure needed for injection moulding process.Certainly
Advantageously, execute closure as quickly as possible, this is because it shortens circulation time and is thus beneficial to production efficiency.
In order to shorten circulation time, attempt to realize fast for injection machine in de10316199a1 as far as possible shortly
The driving of fast stroke and the fast stroke from injection moulding process are to the transition of pressure stroke.This means in terms of regulation technology
With more consumings of configuration aspects, this may also lead to the higher vulnerability to jamming of system naturally.
Content of the invention
The task of the present invention is to provide a kind of method, and on the one hand it realize optimal circulation time, on the other hand permissible
It is performed particularly simply.Additionally, a kind of injection machine allowing the such method of execution should be provided.
This task to complete with injection machine by the following method.
This is accomplished by, i.e. the inevitable response time of actuation gear itself is not as downtime
Waited, but for terminating previous motion.In other words, from the first job step to the second job step transition
During, when being not just at occurring the information that the first job step terminates, just by controlling or adjusting means sends for the second work
Make the activation instruction of step, but control or adjusting means can utilize following probability, i.e. precompute or at least estimate
Go out the end time point (i.e. terminal location time point) of the first job step and also be issued by before this time point for
The activation instruction of two job steps.Here need not be carried out to the end time point (i.e. terminal location time point) of the first job step
Accurately precalculate.It is many that for example sufficient prompting message can show that described terminal location time point also will exist in future
Long.
As the example of the combination being made up of together with actuation gear moveable element, movable mold clamp board can be included
Together with lockable mechanism, blocking mechanism together with for produce the organization of stres of clossing pressure and turntable and mobile station together with
Movable mold clamp board.
The following improvement project of the present invention is related to being made up of together with actuation gear the moveable element of injection machine all the time
As combine.
It can be beneficial that according to the measured value of injection machine and/or according to being stored in control especially in linear motion
Or the data in adjusting means, calculate or otherwise determine a reference position of moveable element, and once can
Moving component passes through this reference position, just activation instruction is sent to actuation gear.
Preferred in the case that an injection moulding process tempestuously changes to next injection moulding process relatively in movement velocity
Regulation, according to the measured value to injection machine and/or according to the data being stored in control or adjusting means, calculates or with other
Mode determines the terminal location time point of moveable element incoming terminal position, and sends before this terminal location time point
Activation instruction.
In order to optimize the circulation time of injection moulding process further, the response time of lockable mechanism can be measured and
Store it in control or adjusting means.Activation instruction can substantially before this terminal location time point away from this terminal location when
Between send when putting the described response time.Certainly, this response time can be also used for determining reference position.
The position measuring instrument that the position of this moveable element is measured can be provided on moveable element.
So these positions may be used for determining the time point sending activation instruction.
The calculating of the time point sending activation instruction, determination and estimation can be realized by different way.
A predicted time for example can be selected；Two positions being measured by position measuring instrument by moveable element
Difference calculate an instantaneous velocity；Assume that moveable element has constant acceleration, by described in described predicted time
Instantaneous velocity calculates change in location, and if the numerical value of described change in location is more than between terminal location and instantaneous position
The numerical value of difference, then send activation instruction.Have an advantage in that without learning cycle, thus simplify the operation to injection machine.
Especially preferably, described predicted time is chosen as roughly equal with the response time, this contributes in this programme
Optimize circulation time.
During once can also closing before closing unit, movable mold clamp board is moved in terminal location
The exercise duration of motion measures, and measured exercise duration is stored in described control or adjusting means
In, and this exercise duration is used for calculating or being used for determining described terminal location time point or reference position.The method
Can particularly simply be realized.
In order to allow control or adjusting means to work in a pulsed fashion, it may be stipulated that: the closure of closing unit is divided
For the constant time step with continuous numbering each other；The location transmission that will be measured by position measuring instrument in each time step
To control or adjusting means；By time step corresponding for the terminal location time point in the front closing course with closing unit
Terminal location numbering be stored in control or adjusting means in；And it is less than described in the closing course of closing unit in numbering
The time step of terminal location numbering sends activation instruction.
The reaction number of such time step, in order to realize optimal circulation time, can be stored in control or adjust by here
In regulating device, i.e. the described response time substantially persistently this stoichiometric number object time step；And the closing course in closing unit
In in such time step by controlling or adjusting means sends activation instruction, that is, the numbering of described time step is compiled with by terminal location
Number with reaction number formed difference corresponding.
Furthermore, it is necessary to protect to the injection machine with closing unit for executing methods described.
