Description

Make the method for loom operation

The present invention relates to a kind of method that makes loom operation, loom has one first drive motors, and it drives a for example slay and have at least one second drive motors of one first element, and it drives for example shed forming device of one second element.

The motion of discrete component must be to coordinate mutually in time in loom.This temporal coordination is known to be in order to obtain when using separate drive motors, detects a main shaft, particularly drives the angle position of the main shaft of a slay, and make the drive motors of other element and these angle positions synchronous.This has brought problem synchronously, because main shaft is with the rotary speed movement that changes.Before the weft yarn that will drop into beat up, the rotating speed of main shaft will descend.When slay with knit when being anchored on the position that reaches the back, the rotating speed of main shaft then will quicken.When the main drive motor of being devoted to for example to make the drive motors of a shed forming device and drive slay is synchronous, the uneven motion of the same execution of the drive motors of this shed forming device for this reason.This just causes, and drive motors and this shed forming device that has born the shed forming device of high load capacity anyway also will bear itself unwanted other load.

For the energy consumption that a complete synchronous operation is needed reduces, known (EP0893535A1) will control with adjusting device and so construct, and make can switch between a rigid and soft readjustment.Under the rigid adjusting situation that is employed between the starting period of loom, the drive motors of shed forming device is followed the main drive motor motion with very accurate synchronism.Yet will be switched in the adjusting of described flexibility weaving run duration normally, wherein the drive motors of shed forming device allows relative synchronous operation that the leading or hysteresis main drive motor in little deviation ground is arranged.

And (EP0946801B1) disclose, control the fabric embedding limit device of a loom independently according to a program and main drive motor, wherein whether monitoring occurs one and exceeds the asynchronous of permissible value.If this asynchronous generation is then implemented a correction according to a correction program.

Known, all elements of a loom are driven by a common main drive motor.In order to carry out pick finding when the staplings, (EP0161012B1) is known in addition, an additional motor is set is used for pick finding and is used for a motion slowly.Main drive motor then when a pick finding by disconnected connection, but thus by additional motor or have only the shed forming device passive movement, perhaps loom moves with small speed.

These identical functions also have (EP0726345A1) known, the driving of loom so are set, so that is to say that weaving operation, pick finding and motion slowly normally only just can realize with a main drive motor.

(FR2660672A1) is known in addition, a drive motors is set is used for shed forming device, and especially for a full-jacquard mechanism, and the another one drive motors is used for all remaining elements of loom.These two drive motors are interconnective by an electromagnetic gear.This electromagnetic gear compares the information of two sensors constantly, that is one detected sensor that loom main shaft rotates and one and detect the sensor that drive motors that shed forming device uses rotates, and guarantee these two motor synchronous ground operations by this way.

Task of the present invention is, so makes the loom operation of the above-mentioned type, makes the drive motors of element need not to overcome unnecessary load as much as possible.

This task so solves, and sets a corner change curve that is used for a false synchronization axle of loom, and makes the element that is driven by drive motors synchronous with the false synchronization axle at least one default angle position respectively.

Basic design of the present invention is that the element of a loom needn't be accurately synchronous mutually continuously in the whole cycle period of weaving, but these single elements only need to be on the suitable position when the angle position of determining.Weave cycle period at remaining, their (elements) can occupy irrelevant position on this quite big degree each other on the contrary.This false synchronization axle is such element, according to it, is not only as the add ons of shed forming device or fabric embedding limit device or coiler device or similar structures and also has slay all will be corrected.Therefore these comprise discrete components of slay just a no longer relative main shaft are synchronous, but relatively this, the false synchronization axle has been transferred synchronously, its slay is also transferred synchronous relatively.Therefore these single elements can so implement their motion, promptly, for their drive motors and/or for these elements itself, small as far as possible load all occurs, be harmonious particularly with the motion of slay and need not make through 360 ° motion process and other elements.The present invention also has advantage especially when loom starts.Driving has the drive motors of the structural detail of big quality, the drive motors of slay for example, and for example just can comparing, a drive motors that is used for shed forming device has been activated more earlier.Start-up time of drive motors, point just can coordinated like this unanimity, that is, they that is these are all occupied desirable angle position respectively by the element that they drove on this correct time point.For example the drive motors of a shed forming device can so be activated, that is, warp thread intersects when corner of 320 ° of the false synchronization axle, and the drive motors of slay is so started simultaneously, that is, beating up of weft yarn taken place when 0 ° of the false synchronization axle or 360 °.Therefore the time point of the startup of drive motors is unessential, on the contrary importantly, all will be on the correct position when the correct time point by element that it drove.

Have a drive motors at one, it drives one first element as a slay, and has at least one second drive motors, and it drives in the loom of one second element as a shed forming device, and the present invention realizes thus:

Control and adjusting device are set, corresponding own control and regulon that it is set the corner change curve of a false synchronization axle that is used for loom and is transferred to drive motors, they make each element that is driven by drive motors synchronous with the false synchronization axle at least one angle position of presetting.

A drive motors that is used for shed forming device oneself is set in organization plan of the present invention, and itself and a main drive motor that drives slay are independently.

Because the drive motors of shed forming device be with main drive motor independently, so it can be by the condition work of optimum.

In a simple embodiment, it requires to change a loom hardly, and the drive motors of shed forming device is positioned on the frame of loom and by an elastic clutch element and is connected with the driving element of shed forming device.This elastic clutch element makes vibration or vibrations not be delivered on other element of loom from shed forming device and is being highly significant aspect the reverse transmission at least.

In another organization plan of the present invention, the drive motors of shed forming device is fixed on the housing, and this housing comprises the driving element that is used for shed forming device.All the other elements of the drive motors of shed forming device and loom separate to the full extent thus, and therefore vibration and vibrations can reciprocally not transmitted on the one hand, also do not need to make simultaneously the driving force commutation on the other hand.

Of the present invention other feature and advantage can from following to embodiment shown in the accompanying drawing explanation and dependent claims obtain.

First drive motors 10 drives a power transmission shaft 12 that is used for slay 13 by a gear stage 11.Second drive motors 44 drives a shed forming device 46 that for example is designed to dobbies by a gear stage 45, and it is connected with unshowned heald frame by connecting rod 47.

Weave cycle period at one, this axle 12 that is commonly referred to as main shaft is carried out one 360 ° rotation.That settles on slay 13 when 0 ° or 360 ° knits the reed weft yarn that penetrates that beats up.That driven that is heald frame that rise and descend then constitutes one a weft yarn is put into wherein race by shed forming device 46 and connecting rod 47 for these.After this picking, race is exchanged by the rise and fall of other heald frame, and after this next weft yarn is dropped into.The exchange of race for example just took place before the weft yarn of this input is finally beaten up.At this, the heald frame warp thread that these move upward intersects with the heald frame warp thread that moves downward.This for example intersects and to take place 40 ° the time at 320 ° corner of axle 12 that is before the weft yarn that will drop into beats up.

In order to make the synchronized movement of slay 13 and shed forming device 46, regulate and control device 48 is used for the corner change curve of a false synchronization axle according to one of data setting by input block 55 inputs for one.Two drive motors 10 and 44 drive according to the corner change curve ground of this false synchronization axle respectively.Drive motors 10 for slay 13 is provided with control and regulon 49, wherein the data that 55 inputs move according to the corner change curve of false synchronization axle by input block.Connect an angle position sensor 50 on this control and regulon 49, its position with axle 12 also provides the position of slay 13 thus.In another embodiment, an angle position sensor 57 is placed on the axle of drive motors 10.Be connected 49 of control on the drive motors 10 and regulons and regulate this drive motors 10 according to rated value, this rated value is to be derived by the corner change curve of false synchronization axle, like this, slay 13 is for example synchronous with the false synchronization axle when an angle position (0 ° or 360 °), that is when a weft yarn is beaten up.This control and regulon 49 also can be for drive motors 10 preestablish a program, and it is consistent with WO9927426 especially.Wherein this control can realize according to a default torque or torque change curve or according to default speed or speed change curves.

Information about the corner change curve of false synchronization axle also is sent on control and the regulon 51 itself and drive motors 44 corresponding configurations.Drive motors 44 drives in such a manner according to the corner change curve of false synchronization axle, make same on a default angle position, for example on the false synchronization axle was one 320 ° angle position, the connecting rod 47 of shed forming device 46 occupied a definite position.An input block 54 is connected on control and the regulon 51, will be input to this unit 51 according to the data that the false synchronization axle is done to move by input block 54.In order to know this position, with angle position sensor 52 of shed forming device 46 corresponding configurations, it is connected on control and the regulon 51.Show that in the accompanying drawings this angle position sensor 52 detects the position of connecting rod 47.But replace it also an angle position sensor 56 can be placed in shed forming device 46 the axle 58 on or with an angle position sensor 59 be placed in drive motors 44 the axle on.

Because drive motors 10 and 44 is fully separated and mutually synchronization mutually, but be in the indirect mutually relation by the false synchronization axle, so they can so be arranged, make them drive affiliated respectively element with small as far as possible power consumption.Wherein also possible is, so control the drive motors 10 of slay 13, make it during the weft yarn that beats up, always make movement of the sley with identical speed or with a speed by input block 53 inputs, and with other speed of loom element that is with irrelevant to the weaving speed that also will change under the stable condition, with this weaving speed, continuous weft yarn is by warp-wise crimp.Just can guarantee that in this way each weft yarn is beaten up with identical or default different power.

Shed forming device for example comprises a dobbies or an other heald frame transmission device, and it is designed to dobbies or cam gear or crank gear or eccentric drive or like configurations.Shed forming device also can be a jacquard attachment.Shed forming device also can so be designed in addition, makes each heald frame independent drive motors of corresponding configuration or every group of heald frame difference correspondence dispose a drive motors.

Control and input block 55 of adjusting device 48 corresponding configurations can be imported in order to constitute the necessary data of false synchronization Shaft angle change curve by it.Control and regulon 49,51 corresponding configuration input blocks 53,54 with drive motors 10,44, can import these data by it, be that they are determined, which angle position or which angle position of relative false synchronization axle, drive motors the 10, the 44th, corresponding synchronous, that is those are corresponding synchronous by the element that this motor drove.

Drive motors 10,44 can be by oneself a corner change curve operation.Drive motors 10,44 can move as disclosed in WO9927426 by the control under respectively and regulon 49,51 signal in conjunction with angle position sensor 50,52.But as preferred, drive motors 10,44 will move with this mode that relies on mutually with false synchronization Shaft angle change curve with the signal of regulon 48 according to control with regulon 49,51 by the control of its correspondence.

Each element is with to also have each drive motors 10,44 to need not to be an angle position of presetting of absolute accurately relative false synchronization axle synchronous.But when these angle positions of their relative false synchronization axles be just enough when synchronous with a small relatively tolerance.Wherein when the angle position of relative false synchronization axle depart from less than 5 ° the time synchronism just enough accurate in general.Tolerance can be defined as different for each picking.

Each element for example slay or shed forming device also can be synchronous with a plurality of angle positions of false synchronization axle in the nature of things.One for the adjusted in concert of slay can be when beating up for example 360 °, when a weft yarn input begins for example 80 ° and when a picking finishes during for example at 240 ° by adjusted in concert.In this synchronous working, the slay between 80 ° and 240 ° of angle positions rests on the position of its back basically.Shed forming device can for the angle position that intersects for example 320 ° the time and when picking begins for example at 80 ° and when picking finishes for example at 240 ° by adjusted in concert that is in the meantime this race must remain on open wide enough wide.

When the gearratio between drive motors and driven element was an integer, then undoubtedly possible was that drive motors is made adjusted in concert with the angle position that is not the relative false synchronization axle of this driven element.

Can be for the corner change curve that the false synchronization axle is constituted based on the constant rotating speed.Stipulate that preferably the corner change curve is determined by a plurality of weft yarn inputs and repeated accordingly then.At this, this corner change curve can be at the warp thread access node that takes place about weft yarn, successively, from bottom to top or from the top down be determined or be determined according to other condition in the multiple function different, that will be placed into successively of the quantity of the warp thread of passive movement.Especially, determine that a suitable corner change curve is used for the false synchronization axle that loom starts and stops.

Can stipulate that similarly the angle position of false synchronization axle is changed, relatively its, an element is transferred synchronously.Be used for a plurality of pickings when a corner change curve of for example false synchronization axle is determined, for example during three pickings, then can stipulate, when being used for shed forming device that warp thread intersects first picking of 320 °, in second picking of 315 ° and the 3rd picking at 310 ° is synchronous, and after this this process repeats.

False synchronization Shaft angle change curve of the present invention's foundation then also can be applicable to drive other element to the control or the adjusting of drive motors in other organization plan of the present invention, for example be used to drive motor or the motor of a selvedge formation device or the motor of similar device of a fabric wrapping motor, a fabric embedding limit device.The present invention also can be applied to driving a so-called Jacquard thunder spy in addition, that is the jacquard attachment of a miniaturization, the warp thread of a minor amount of its operation, and 100 warp thread for example, remaining warp thread is operated by heald frame or a large-scale jacquard attachment simultaneously.
