Description

method of making the loom run

technical field

The invention relates to a method for operating a loom having a first drive motor which drives a first element such as a sley and at least one second drive motor which drives a second element such as a shuttle Mouth-forming apparatus.

Background technique

The movements of the individual elements in a weaving machine must be coordinated with each other in time. In order to achieve this temporal coordination when using mutually independent drive motors, it is known to detect the angular positions of a spindle, in particular a spindle that drives a sley, and to synchronize the drive motors of the other elements with these angular positions. This synchronization poses problems because the spindles move at varying speeds. Before the input weft yarn is beaten up, the rotational speed of the main shaft is decreased. When the sley and the knitting button arrive at the position behind, the rotating speed of the main shaft will be accelerated. When, for example, efforts are made to synchronize the drive motor of a shedding device with the main drive motor driving the sley, the drive motor of the shedding device likewise performs an uneven movement for this purpose. This has the result that the drive motor of the shedding device, which is already subjected to a high load anyway, and the shedding device are also subjected to additional loads which are not themselves required.

In order to reduce the energy consumption required for a fully synchronous operation, it is known (EP 0893535 A1) to design the control and regulating device in such a way that it can be switched between a hard and a soft regulation. In the case of hard adjustments applied during start-up of the loom, the drive motor of the shedding device follows the movement of the main drive motor with very precise synchrony. During normal weaving operation, however, a switch is made to the flexible adjustment, wherein the drive motor of the shedding device is allowed to lead or lag the main drive motor with a slight deviation relative to synchronous operation.

Furthermore (EP0946801B1) it is known to control the weaving device of a weaving machine independently of the main drive motor according to a program, wherein it is monitored whether a non-synchronization exceeding a permissible value occurs. If this asynchrony occurs, a correction is carried out according to a correction procedure.

It is already known to drive all elements of a weaving machine by means of a common main drive motor. In order to be able to find a weft break when the weft is broken, it is also known (EP0161012B1) to provide an additional motor for finding a weft break and for a slow motion. The main drive motor is disconnected when a weft break is detected, so that either only the shedding device can be moved by means of an additional motor, or the loom runs at a slight speed.

Also (EP0726345A1) is known, so that the drive of the loom is set so that these same functions, that is to say normal weaving operation, finding broken wefts and slow motion, can be realized with only one main drive motor.

Furthermore (FR2660672A1) it is known to provide a drive motor for the shedding device, in particular for a jacquard mechanism, and a further drive motor for all the remaining elements of the weaving machine. The two drive motors are interconnected via an electronic transmission. This electronic transmission continuously compares the information of two sensors, namely a sensor detecting the rotation of the main shaft of the loom and a sensor detecting the rotation of the drive motor for the shed forming device, and in this way ensures that the two motors are synchronized to run.

Contents of the invention

The object of the invention is to operate a weaving machine of the above-mentioned type in such a way that as far as possible the drive motors of the elements do not have to overcome unnecessary loads.

This object is solved by setting a rotational angle curve for a virtual synchronous shaft of the weaving machine and synchronizing the elements driven by the drive motor with the virtual synchronous shaft in each case at at least one predetermined rotational angle position.

The basic idea of the invention is that the elements of a weaving machine do not have to be continuously and precisely synchronized with one another during the entire weaving cycle, but the individual elements only need to be in the correct position at certain corner positions. During the rest of the weaving cycle, they (elements) can instead occupy such mutually largely independent positions. The virtual synchronizing shaft is the element according to which not only additional elements such as the shedding device or the fabric trimming device or the winding device or the like but also the sley are to be corrected. These individual elements, including the sley, are therefore no longer synchronized with respect to a main shaft, but with respect to which the virtual synchronizing shaft is synchronized, with respect to which even the sley is also synchronized. The individual elements can therefore carry out their movements in such a way that the least possible loads occur on their drive motors and/or on the elements themselves without interfering with other elements, especially Movement with the sley is coordinated. The invention also has advantages especially at the start-up of the loom. A drive motor that drives a structural element with a greater mass, such as the drive motor of the sley, can be activated earlier than, for example, a drive motor for the shedding device. The start-up times of the drive motors can then be coordinated in such a way that they, ie, the elements driven by them, each assume the desired angular position at this correct time. For example, the drive motor of a shed forming device can be activated in such a way that the warp yarns cross at a 320° angle of rotation of the virtual synchronous axis, while the drive motor of the sley is activated in such a way that the beating of the weft yarn is performed in the virtual synchronous Occurs at 0° or 360° of the axis. Therefore, the starting time of the driving motor is not important, but what is important is that the components driven by it are in the correct position at the correct time.

In a loom with a drive motor that drives a first element such as a sley, and at least one second drive motor that drives a second element such as a shed forming device, the present invention is thus achieved:

A control and regulation device is provided, which sets a curve of rotation angle for the virtual synchronous shaft of the weaving machine and forwards it to the corresponding own control and regulation unit of the drive motor, which makes each element driven by the drive motor Synchronize with virtual synchronous axes at least one preset angular position.

In an embodiment of the invention, a drive motor for the shedding device itself is provided, which is independent of a main drive motor for driving the sley.

Because the driving motor of the shed forming device is independent from the main driving motor, it can work under optimal conditions.

In a simple embodiment, which requires little modification of a weaving machine, the drive motor of the shedding device is mounted on a frame of the weaving machine and is connected to the transmission element of the shedding device via an elastic clutch element . This elastic coupling element is at least meaningful in that vibrations or shocks are not transmitted from the shedding device to other elements of the weaving machine and vice versa.

In a further refinement of the invention, the drive motor of the shedding device is mounted on a housing which contains the transmission elements for the shedding device. The drive motor of the shedding device is thus separated to the greatest extent from the remaining components of the weaving machine, so that on the one hand oscillations and vibrations are not transmitted to each other and on the other hand no reversing of the drive force is required.

with the first drive motor and/or the sley and the at least one second drive motor and/or the transmission element driven by the at least one second drive motor and/or by the at least one second drive motor by means of the The shedding device driven by the transmission element is correspondingly equipped with a sensor which detects the rotational angular position of the corresponding member.

Detailed ways

The first drive motor 10 drives a drive shaft 12 for the sley 13 via a step transmission 11 . The second drive motor 44 drives via a step drive 45 a shedding device 46 , designed for example as a dobby, which is connected via a connecting rod 47 to a not shown heald frame.

During a weaving cycle, this shaft 12, generally called the main shaft, performs a 360° rotation. The reed placed on the sley 13 beats up an inserted weft thread at 0° or 360°. These heald frames driven by the shed forming device 46 and the connecting rod 47, ie rising and falling, then form a shedway into which a weft thread is dropped. After this weft insertion, the shed is exchanged by raising and lowering another heald frame, after which the next weft thread is thrown in. The exchange of the shed, for example, takes place before the weft thread that is put in is finally beaten up. Here, these upwardly moving heald frame warp threads cross the downwardly moving heald frame warp threads. This intersection takes place, for example, at an angle of rotation of 320° of the shaft 12, ie 40° before the weft thread fed in is beaten up.

In order to synchronize the movements of the sley 13 and the shedding device 46 , a regulating and control device 48 sets a rotational angle curve for a virtual synchronizing axis on the basis of the data input via the input unit 55 . The two drive motors 10 and 44 are each driven according to the rotational angle profile of this virtual synchronous shaft. A control and regulation unit 49 is provided for the drive motor 10 of the sley 13 , in which data are input via an input unit 55 which operates according to the curve of the rotational angle of the imaginary synchronous shaft. An angular position sensor 50 is connected to the control and regulating unit 49 , which indicates the position of the shaft 12 and thus the position of the sley 13 . In another embodiment, an angular position sensor 57 is arranged on the shaft of the drive motor 10 . The control and regulation unit 49 that is connected on the drive motor 10 then regulates this drive motor 10 according to the nominal value, and this nominal value is deduced by the rotational angle variation curve of virtual synchronous shaft, like this, sley 13 is for example in a rotational angle position (0 ° or 360°), it is synchronized with the virtual synchronous axis, that is, when beating up a weft yarn. The control and regulation unit 49 can also preset a program for the drive motor 10 , which is in particular in accordance with WO9927426. The control can be carried out according to a preset torque or torque profile or according to a preset speed or speed profile.

Information about the profile of the rotational angle of the virtual synchronous shaft is also transmitted to a control and regulation unit 51 , which is associated with the drive motor 44 . The drive motor 44 is driven in such a way according to the angle of rotation curve of the virtual synchronous shaft that also at a preset rotational angle position, for example, at a rotational angle position of 320° at the virtual synchronous shaft, the connecting rod 47 of the shed forming device 46 occupy a definite position. An input unit 54 is connected to the control and regulation unit 51 , by means of which the data for the operation according to the virtual synchronous axis are input to the unit 51 . In order to detect this position, an angular position sensor 52 is assigned to the shedding device 46 , which is connected to the control and regulation unit 51 . It is shown in the drawing that this angular position sensor 52 detects the position of the connecting rod 47 . Instead, however, it is also possible to arrange an angular position sensor 56 on the shaft 58 of the shedding device 46 or an angular position sensor 59 on the shaft of the drive motor 44 .

Since the drive motors 10 and 44 are completely separated from each other and are not synchronized with each other, but are in an indirect relationship to each other via a virtual synchronous shaft, they can be arranged in such a way that they drive the respective motors with as little effort as possible. components. Wherein it is also possible to control the drive motor 10 of the sley 13 in such a way that it always moves the sley at the same speed or at a speed input by the input unit 53 during beating-up of a weft thread, while the loom elements The other speeds, ie the weaving speeds which also vary in a given case, are independent of the weaving speed at which successive weft threads are shrunk in the warp direction. In this way it can be ensured that each weft thread is beaten up with the same or preset different forces.

The shedding device comprises, for example, a dobby or another heald frame drive, which is designed as a dobby or cam drive or crank drive or eccentric drive or similar. The shedding device can also be a jacquard device. Furthermore, the shedding device can also be designed in such a way that each heald frame is assigned a separate drive motor or each group of heald frames is assigned a respective drive motor.

The control and regulating device 48 is associated with an input unit 55 , via which the data necessary for forming the curve of the rotational angle of the virtual synchronous shaft can be input. Corresponding to the control and regulation unit 49 , 51 of the drive motor 10 , 44 is the input unit 53 , 54 , through which the data can be input, that is, they determine which angular position or angular positions of the virtual synchronous shaft the drive motor 10 , 54 44 is correspondingly synchronous, that is, those elements driven by the motor are correspondingly synchronous.

The drive motors 10, 44 can be operated with an own rotation angle profile. The drive motors 10 , 44 can be operated by means of the respective associated control and regulation units 49 , 51 in conjunction with the signals of the rotational angle position sensors 50 , 52 as disclosed in WO9927426. Preferably, however, the drive motors 10 , 44 are operated by means of their associated control and regulation units 49 , 51 as a function of the signals of the control and regulation unit 48 and in this manner dependent on the angular profile of the virtual synchronous shaft.

Each element and also each drive motor 10 , 44 does not have to be synchronized absolutely precisely with respect to a predetermined angular position of the virtual synchronization shaft. Rather, it is sufficient if their angular positions relative to the virtual synchronous axis are synchronized with a relatively small tolerance. In this case, the synchronization is generally sufficiently precise when the deviation of the rotational angular position relative to the virtual synchronization axis is less than 5°. The tolerance value can be determined differently for each weft insertion.

Each element, such as a sley or a shedding device, can of course also be synchronized with several angular positions of the virtual synchronization shaft. A synchronous adjustment for the sley can be adjusted synchronously when beating up, for example at 360°, at the beginning of a weft thread input, for example at 80°, and at the end of a weft insertion, for example at 240°. During this synchronous operation, the sley between the angular positions of 80° and 240° essentially remains in its rearward position. The shed forming device can be adjusted synchronously for the angular position of the intersection, for example at 320° and at the beginning of weft insertion, for example at 80°, and at the end of weft insertion, for example at 240°, i.e. the shed must remain open during this time wide enough.

If the transmission ratio between the drive motor and the driven element is an integer, it is of course possible to adjust the angular position of the drive motor and not the driven element synchronously relative to the virtual synchronous shaft.

The angle profile formed for the virtual synchronous shaft can be based on a constant rotational speed. It is preferably provided that the rotation angle profile is determined over a plurality of weft thread inputs and is then correspondingly repeated. In this case, the curve of the angle of rotation can be determined in various functions to be inserted one after the other with respect to the weft thread, the warp thread binding that occurs in succession, the number of warp threads moved from bottom to top or from top to bottom, or determined according to other conditions. In particular, it is necessary to determine a suitable rotation angle curve for the virtual synchronous axis of the loom starting and stopping.

It can likewise be provided that the angular position of the imaginary synchronous axis is changed, relative to which an element is synchronized. When for example a rotation angle profile of the virtual synchronous shaft is determined for multiple weft insertions, for example three weft insertions, then it can be stipulated that the shed forming device for warp yarn crossing is at the first weft insertion of 320°, at The second weft insertion at 315° is synchronized with the third weft insertion at 310°, after which the process is repeated.

The control or adjustment of the drive motor according to a virtual synchronous shaft angle change curve of the present invention can also be applied to drive other elements in other structural solutions of the present invention, such as for driving a fabric winding motor, a fabric edge device , or a motor of a selvedge forming device or a similar device. Furthermore the invention can also be applied to drive a so-called jacquard, i.e. a miniaturized jacquard unit which operates only a small number of warp threads, say 100 warp threads, while the rest of the warp threads are passed through heald frames or a large jacquard device to operate.

The loom drive partly shown in FIG. 2 comprises a main drive motor 10, which drives a shaft 12 via a step transmission 11, on which cam discs (on both sides of the machine) not shown in detail are arranged. , which drive a sley 13. The main drive motor can also drive other components, such as a cloth guide shaft, a cloth take-up roller, edger, edger and winding device. According to the invention, for the transmission element 14 of the shed forming device - which can be designed as a dobby or cam drive or crank drive or a dobby loom or heald frame drive - an own drive motor 15 is provided, which It is independent with the main drive motor 10. The drive motor 15 drives a shaft 17 via a step transmission 16 , and the shaft 17 drives a shaft 20 of the transmission element 14 via a spring coupling 18 and a bevel gear step 19 . From this rotational movement of the shaft 20 , which extends transversely to the axis of the main drive motor 10 , the first driven transmission is the transmission which executes a reciprocating movement parallel to the axis of the main drive motor 10 . From this transmission is then transmitted an up and down motion in the vertical direction.

In the exemplary embodiment of FIG. 2 , a braking device 22 and an angular position sensor 23 are provided for the shaft 17 . Moreover, a rotational angle position sensor 24 is configured correspondingly to the main drive motor 10 . The angular position sensors 23 , 24 are connected in a suitable manner to the control and regulation unit of the weaving machine, as in FIG. 1 the angular position sensors 50 , 52 are connected to the control and regulation units 48 , 49 and 51 . The control and regulation units 48, 49 and 51 may be included in the control and regulation unit of the weaving machine. This (control and regulating unit) predetermines the setpoint rotational speeds to be regulated for the main drive motor 10 and the drive motor 15 of the shedding device. These setpoint speeds relate to the speed of an imaginary main shaft, which is determined by the control and regulating unit. Furthermore, the main drive motor 10 and the drive motor 15 are each synchronized by at least one rotational angular position relative to the virtual main axis, wherein they ( 10 , 15 ) occupy the rotational angular position associated with the virtual main axis. For example, the main drive motor 10 is synchronized at the angular position 0° (weft yarn beating up), and the drive motor 15 is synchronized at 320° (warp yarn crossing). The rotational speeds of the main drive motor 10 and the drive motor 15 are adjusted independently of one another to corresponding setpoint values, so that neither drive motor 10 or 15 has to be driven in accordance with the rotational speed profile of the other drive motor.

In the embodiment of FIG. 2, the stage transmissions 11 and 16 are accommodated in a common transmission housing 25, which is preferably integrally formed in a side member of the weaving machine. The main driving motor 10 and the driving motor 15 are arranged on the same side, that is, the outer side.

In the embodiment of FIG. 3, the stage transmission 17 for the transmission element 14 and thus for the drive motor 15 of the shedding device is not arranged inside the transmission housing 26, which (26) contains the sley drive The stage transmission device 11 of the device. A separate transmission housing 27 , which ( 27 ) contains the step transmission 16 , is flanged to the transmission housing 26 . In this embodiment, the drive motor 15 of the shedding device is arranged on the side opposite the main drive motor 10 . An angular position sensor or rotational speed sensor 28 is assigned to the shaft 17 in this exemplary embodiment. A braking device 29 can be integrated in the drive motor 15 .

The exemplary embodiment in FIG. 4 corresponds to the exemplary embodiment in FIG. 3 in terms of its basic structure. In addition, a braking device 29 and another rotational angle position sensor or rotational speed sensor 31 are arranged correspondingly to the drive motor 15 of the shed forming device. Furthermore, the main drive motor 10 is also equipped with a braking device 30 .

In the exemplary embodiment of FIG. 5 , the transmission housing 32 of the main drive is completely separate from the transmission housing 33 of the drive for the transmission element 14 . The transmission housing 33 contains the step transmission 16 and to which the drive motor 15 is flanged, which ( 33 ) is fastened to the housing of the transmission element 14 . The stage transmission 16 is directly connected to the bevel gear stage 19 , ie without an intermediate spring coupling. In this embodiment, the drive motor 15 of the shedding device is arranged such that its axis runs parallel to the axis of the main drive motor 10 . Since the transmission housing 33 is completely separate from the transmission housing 32 of the stage transmission 11 of the main drive motor 10, it is of course also possible without any doubt that the transmission housing 33 and the drive motor 15 are placed in the transmission. Above or below or on the opposite side of the housing of the element 14 .

In the embodiment of FIG. 6 , the drive motor 15 for the transmission element 14 and thus for the shedding device is also completely separated from the rest of the weaving machine. The stage transmission 16 is placed in a transmission housing 33 , which ( 33 ) is flanged to the housing of the transmission element 14 in such a way that the shaft 17 extends coaxially with the shaft 20 , which ( 20 ) can lead to A reciprocating linear movement parallel to the axis of the main drive motor 10 . In a variant embodiment, the transmission housing 33 and the flanged drive motor 15 are then arranged on opposite sides of the transmission element 14 .

In the embodiment of FIG. 7 , the drive motor 15 for the transmission element 14 and thus for the shedding device is flanged directly to the housing of the transmission element 14 in such a way that the axis of the drive motor 15 is aligned with the transmission. The shaft 20 of the element 14 extends coaxially.

The technical solution of the present invention, that is to provide a drive motor that can be driven independently from the main drive motor 10 of the loom for the shed forming device, is implemented in the embodiment of Fig. 8 for a loom 36, which Equipped with a jacquard device 37 . The weaving machine 36 has a main drive motor 10 which drives a shaft 12 provided with a cam for the sley 13 via a step transmission. The stage transmission 11 is accommodated in a transmission housing 32 which is integrated in a side member of the weaving machine. The jacquard device 37 arranged above the weaving machine 36 on the frame 38 is provided with its own drive motor 15 . In the present exemplary embodiment, the drive motor 15 is flanged to a transmission housing 33 . The output shaft 17 of the stage drive 16 is preferably directly connected to the shaft of the Jacquard device 37, ie is arranged coaxially with this shaft. In a variant embodiment, a transmission housing 33 is omitted, since the step transmission 16 is directly integrated in the jacquard 37 in one piece. In another variant embodiment, the drive motor 15 is directly connected to the Jacquard device 37, ie without a step transmission.

Because there is no mechanical connection between the main drive motor 10 and the drive motor 15 for the drive elements of the shed forming device, these always spatially most advantageous configurations can be selected, not only for the jacquard device 37 but also for the Heald frame transmission. The heald frame drive and a jacquard device 17 can form a prefabricated structural unit with the corresponding drive motor 15, which is configured correspondingly to the corresponding loom.
