Description

DESCRIPTION

Fachbild orrichtung

The invention relates to a shedding device,

in particular a jacquard machine, with the features in the preamble of the main claim.

From practice shedding devices with a derived from the weaving machine by means of cardan drive for the up and down movable platinum carrier are known. The at the end areas of the platinum carrier directly or

optionally acting on a knife box

Adjusting means for transmitting the drive movement are jointly driven centrally and move synchronously.

It is an object of the present invention to provide a

to show improved box imaging technology.

The invention solves this problem with the features in the main claim.

The claimed shedding technique, i. the

Shedding apparatus and associated method have several advantages.

The formation of the drive device with independent and preferably separately driven actuating means expands the setting and control options for the

Drive device and for the kinematics of

Supported platinum. The independently driven actuating means are drive-driven by the drive of the loom

independent and are only adapted to this tax technology. A separate drive of the actuating means allows an independent influence on the kinematics of the

different actuating means. The actuating means are controlled differently. They can each be connected to one or more own drive motors. The

Adjusting means can be driven and controlled separately from one another at the respective end regions of the platinum carriers. Alternatively, a common drive of the various actuating means is possible. The different controllability of the adjusting means is e.g. about one

adjustable intermediate gear possible.

The actuating means of the drive device may have a different drive kinematics. They each have their own drive kinematics, which may differ from that of the other actuating means. Kinematics differences may be e.g. in a

Phase shift of the drive movements exist. The drive kinematics can also be chosen, e.g.

in terms of paths, speeds and / or

Accelerations and possible rest periods.

In a further inventive concept, the

Drive device also different set adjusting means. This allows one from the state of

Technique deviating kinematics and orientation of the up and down movable platinum carrier. The various actuating means are each independently controllable and optionally independently adjustable. As a result, the claimed different control and possibly

achieved different adjustment of the actuating means and, if necessary, be changed.

In a further inventive idea is the

Drive device designed and controlled so that they tilt at a movement cycle, the board carrier or the array of platinum carriers temporarily provides. As a result, the platinum carriers can take an inclined position at least temporarily in their longitudinal extent. The ends of the platinum carriers can

different strokes at the up and down

Move downwards. The tilt and the

strokes of different sizes also have an effect on the boards which can be attached to the platinum carriers in a controlled manner and on the warp threads connected to them. This allows the warp threads also in the shedding

Run different strokes or have different large deflection. On the one hand, this is advantageous for the mutual separation of warp threads.

On the other hand, a sufficiently large compartment opening for the shot can always be achieved.

An inclination of the platinum carrier in their

Longitudinal stretching is particularly advantageous for platinum carriers, which are aligned along the warp direction. However, the invention can also be used for transverse to the warp direction platinum carriers, which in a

Row arrangement arranged in the warp direction one behind the other and located in a so-called knife box.

Here, e.g. the ends of the platinum carrier may be connected by a common support beam, wherein the adjusting means, as required, may obliquely set the support beam and thus the series arrangement of the platinum carrier. The front in the series arrangement Platinenträger lead here, for. a smaller vertical stroke than the rear plate carrier. In addition, also in one

Knife box board makers take a skew in their longitudinal extent, the end-side

Carrying beams of different strokes.

The drive device may also be designed and controlled in such a way that the respective board carrier is involved in a movement cycle at its carrier ends

different kinematics is moved. Here he can be moved at its respective carrier ends at different speeds and / or accelerations. This also includes temporary rest periods or rest positions within a cycle.

The aforementioned embodiments of the invention

Drive device have a number of advantages for the weaving technique. If different bindings,

In particular, a pile weave and a plain weave, are generated on the web product can be generated in the specialized education more definable and controllable departments for the different bindings.

For the structural and tax technical implementation of the aforementioned drive technology, it is advantageous if the drive device one or more own

Having drive motors for the actuating means. It is particularly favorable if this one or more independently controllable drive motors, preferably electrical

Servo motors, are.

Furthermore, it is advantageous if an actuating means a

Crankshaft has. This one can be different

set and / or driven differently. Preferably, the crank mechanism has one or more

revolving or oscillating driven crankshafts with a crank, which connects the crankshaft with an end portion of a platinum carrier. These

Connection can be made directly or indirectly via a

Stringer or a knife box done.

In one embodiment, an actuating means may be a

Drive shaft with a drive motor and with a

Have transfer gear for the crank mechanism. The

Drive shaft can be connected via the transfer gearbox with several crankshafts. This allows eg a different, in particular opposite kinematics of Platinum carriers, for example, there is a phase shift of 180 °. As a result, for example, a Doppelhub- shedding device can be created. In a particularly preferred embodiment, a

Adjusting means on a directly driven crankshaft with a drive motor. The different crankshafts can be independently driven and their kinematics controlled. Particular advantages are the formation of the one or more drive motors as electrical torque

Engine. This can be arranged on the drive shaft or the crankshaft. In particular, a drive motor within a frame of the drive device

be arranged to save space. Outside the rack, other components of the drive device, e.g. a braking device or the transfer gear can be arranged.

In the subclaims are further advantageous

Embodiments of the invention indicated.

The invention is illustrated by way of example and schematically in the drawings. In detail show:

a schematic view of a loom and a shedding device a perspective view of a

Drive device of the shedding device a cross section through the drive device with viewing direction according to arrow III of Figure 2.

The invention relates to a shedding device (1), in particular a Jacquard machine, and a

Shedding method.

The shed forming device (1) is intended for use on a weaving machine (2) and serves for the controlled lifting and lowering of the warp threads (3), wherein in each case a shed (4), in particular an open shed, is formed. Figure 1 shows this arrangement of shedding device (1) and

Weaving machine (2) in a schematic and aborted representation.

The warp threads (3) are fed by a supply roll in

Warp direction (32) deducted. They are passably connected to strands (5) or so-called harness cords of the shedding device (1), e.g. by means of eyes or rings on the end regions of the strands (5). In Figure 1, the joints are shown as dots. The strands (5) are connected at one end, in particular at the upper end region, to a drive device (15). This is also called knife drive. At the other, in particular

lower, end they are connected to a return divider (6), which is designed as a spring, for example. After this Weft insertion in the compartment (4), the fabric is wound on another roll.

The strands (5) are connected at the upper end with boards (9,10) directly or indirectly via a pulley train (8). The sinkers (9,10) can be used to raise and lower the strands (5) and the warp threads (3) of the

Drive device (15) are moved. The plurality of strands (5) form a harness (7), wherein the strands (5) at the lower harness area narrower than in the upper

Harness area are bundled. The strands (5) extend through openings of intermediate floors.

In the illustrated embodiment, the strands (5) are guided at their upper end in each case via a lower roller of the associated roller pull (8) and secured to the intermediate bottom. On the upper roller of the pulley (8) are two boards (9,10) via a connecting cord

docked.

The boards (9,10) are each one

Platinum carrier (11,12) moved up and down. The

Platinum carriers (11,12) are also referred to as knives. The circuit boards (9, 10) can be connected or disconnected to the platinum carriers (11, 12) by means of a controllable coupling device (not shown) and lifted or lifted

Senkstellung be arrested. The controllable up and down movements of the platinum carrier (11,12) and the boards (9,10), the roller trains (8) and the strands (5) are raised and lowered.

The shedding device (1) has a

Drive device (15) for the board carrier (11,12). The drive device (15) has driven

Adjusting means (17,18), which at the end regions

(13,14) of the platinum carriers (11,12) act. You can attack directly on the front side of the end of the carrier or continue offset inwards and possibly from another direction on the board carrier (11,12) attack.

The adjusting means (17,18) transmit the drive movement of one or more drive motors (29,30,31) on the

Platinum carrier (11,12) and their respective end portions (13, 14).

The platinum carrier (11,12) are preferably designed as narrow strips and straight and along the

Kettrichtung (32) aligned. In Figure 1 this is

Arrangement in the left half of the drive device (15) shown schematically. in another and explained in more detail below

Embodiment, the platinum carriers (11, 12) can be oriented transversely to the warp direction (32) or in the weft direction. You can in a so-called knife box

be arranged. You can thereby with their end portions (13,14) each with a transverse support beam

be connected. On the stringers each intervenes

Adjusting means (17,18) on.

Figures 2 and 3 show a preferred embodiment of the drive device (15). The platinum carrier (11,12) are in this embodiment along the warp direction (32)

aligned.

The platinum carriers (11,12) are from the

Drive device (15) cyclically up and down. This is preferably done in the vertical direction. The

Platinum carriers (11,12) can optionally all simultaneously or in groups offset in time and with a

Phase angle of e.g. 180 ° raised and lowered. In the lower end position, the platinum carriers (11, 12) can each be aligned horizontally. The lower

End positions of the platinum carriers (11,12) can all be offset equal or in height.

During a movement cycle, the platinum carriers (11, 12) are temporarily inclined with their longitudinal extent. The stroke at one end portion (14) is e.g. larger than at the other end region (13). Figures 2 and 3 show this inclination on an upper plate carrier (11). The other board carrier (12) is shown in its lower and preferably horizontal end position. The drive device (15) is for generating these

Platinum carrier movements designed and controlled accordingly.

The adjusting means (17,18) of the drive device (15) are driven independently. They are for this purpose with one or more own drive motors (29,30,31)

Drive device (15) connected. The adjusting means

(17,18) thereby perform in the shedding independently driven and controlled drive movements for the platinum carrier (11,12). These drive movements are independent of the or the drive devices of the loom (2) in terms of force or torque transmission and the stroke. For the correct execution of the

Fachbilde- and weaving process finds a tax technical adaptation of the drive motors (29,30,31) and the

Drive movement of the adjusting means (17,18) to the

Loom drives take place.

In the preferred embodiment, the adjusting means (17,18) are independent and also driven separately. The drive kinematics of the actuating means (17,18) can be different. In the illustrated and preferred embodiment, the two actuating means (17,18) are driven and controlled separately. In another and not shown embodiment, the adjusting means (17,18), although independent, but it

be driven together. The adjusting means (17, 18) of the drive device (15) can be adjusted and / or controlled independently. This allows different setting and

Control relationships of the adjusting means (17,18) with each other.

In the illustrated and preferred embodiment, the adjusting means (17,18) are set differently and / or differently controlled. As a result, the respective end regions (13, 14) of the platinum carriers (11, 12) act differently

Move out. These differences in movement may exist in the way, in particular in the hub, and / or in the kinematics. Kinematic differences in movement can occur in

different speeds and / or

Expressing accelerations of the end regions (13, 14). The

Movement differences relate in each case to a movement cycle with a lifting and lowering movement of the respective platinum carrier (11, 12).

The drive device (15) has the above-mentioned one or more own drive motors (29,30,31) for the actuating means (17.18). The one or more

Drive motors (29,30,31) are preferably independently controllable. You can in any suitable way

be educated. Preferably they are as

Electric motors, in particular designed as electric servomotors. The drive motors (29,30,31) lead in the shown

Embodiments of a rotary drive movement. The motor kinematics can be selected as desired. In another alternative embodiment, they may e.g. perform a linear movement, being electrical

Linear motors or fluidic, in particular pneumatic, drive motors or cylinders or are formed in another suitable manner. As shown in FIGS. 2 and 3, the adjusting means (17, 18) each have a crank drive (19). The shown

Crank drive (19) comprises one or more circumferentially or oscillating driven adjusting shafts (20), in particular

Crankshafts, with a crank (21). The adjusting crank (21) connects the crankshaft (20) to an end region (13, 14) of a platinum carrier (11, 12). The lined up according to Figure 2 and 3 in the weft direction side by side

Platinum carrier (11,12) are at their respective end via its own crank (21) with the associated

Crankshaft (20) connected. On the crankshaft (20) a plurality of cranks (21) are thereby arranged one behind the other in the axial direction.

The cranks (21) are shown in the

Embodiments formed multiarmed. They each have a drive arm (22), which is rotatably connected to the associated crankshaft (20) at one end. The other end of the drive arm (22) is via a drive rod

(22 ') with end pivot bearings with an end portion

(13:14). The drive rods (22 ') have an upright position and are transverse to their platinum carrier

(11,12).

The aforementioned different adjustability of

Adjusting means (17,18) can be given in different ways. According to FIG. 3, it is realized via the adjusting cranks (21). The drive arms (22) of the left

Adjusting means (17) according to Figure 3 has a shorter length than the drive arms (22) of the right actuating means (18). The different driving arm lengths generate different strokes of the respectively connected end region (13, 14) during a movement cycle and bring about the oblique position of the respective platinum carrier (11) shown in FIG. In the embodiments shown, the crankshafts (20) are driven in an oscillating manner. They thereby rotate by an angle of less than 360 ° reversing clockwise and counterclockwise. The adjusting means (17,18) each have a drive shaft (25) with a

Drive motor (29,30) and with a transfer gear (26) for the crank mechanism (19). In this case, the individual drive shaft (25) via the transfer gear (26) preferably with a plurality, e.g. two, crankshafts (20) connected. It thereby drives several, preferably two, platinum carriers (11, 12) simultaneously. Alternatively, the drive shaft (25) may have only one crankshaft (20) or three or more

Drive crankshafts (20). In the shown

Embodiments, the crankshafts (20) are arranged above and below the central drive shaft (25), preferably with their central axes in a vertical line.

The transfer gear (26) are each formed by a on the drive shaft (25) eccentrically arranged link disc (27) or cam and each of a roller (28) on the adjusting crank (21). The rollers (28) are each arranged at the end on a crank arm, which in turn rotatably connected to the associated crankshaft (20) and associated with the drive arm (22). The

Rollers (28) roll with their roller circumference on the circumference of the crank disc (27). An indicated in Figure 2 clamping device secures the system and the motion transmission. The drive shafts (25) are each connected to one or more drive motors (29, 30). In the shown

Exemplary embodiments, two drive motors (29,30) are provided, which are arranged on or on the drive shaft (25). The drive motors (29,30) are e.g. designed as electrical torque motors, located at the

Support frame (16) of drive device (15). The drive motors (29,30) are preferably within the Rack (16) arranged.

The drive shafts (25) and crankshafts (20) are with

Rotary bearings, in particular rolling bearings, mounted on the frame (16). The frame (16) has for this purpose e.g. according to FIG

2 and 3 two end frame plates on. The

Drive motors (29,30) are on the frame plates

supported at the end. The crank mechanisms (19) are located inside the frame (16). The transfer gear (26) can outside the frame (16) and to the there

be arranged projecting shaft ends. One or more shaft ends may also have additional ones

Components, e.g. a brake (24), be arranged. in the illustrated embodiments, the drive

Drive motors (29,30) their respective drive shaft (25) circumferentially, wherein the transfer gear (26) implement the circumferential drive movement in an oscillating drive movement of the control shafts or crankshafts (20).

In Figure 2, a variant is indicated schematically and dashed in the left half of the figure. Here, e.g. a crankshaft (20) of one or more

Drive motors (31) driven directly and reversing. The one or more drive motors (31) can on the

Stellwelle or crankshaft (20) arranged and, for. be designed as a torque motor. In a preferred

Variant all Stell- or crankshafts (20) each have one or more own drive motors (31). In another embodiment, individual actuating or

Have crankshaft (20) one or more drive motors (31), wherein the drive movement can be transmitted via a suitable transmission technology to other actuating or crankshafts. The different setting or control of

Adjusting means (17, 18) can be achieved in different ways. In the illustrated embodiments of the adjusting means (17, 18) with drive shaft (25) and

Transfer gears (26) may e.g. the transfer gear (26) be set differently. Here, e.g. the link plates (27) of the actuators (17, 18) have a different shape and eccentricity. They can be changed as needed for a different setting.

The slide or cams (27) may, as in the embodiments shown have a circular circumference and eccentrically with the drive shaft (25) rotatably connected. The circumferential geometry may alternatively deviate from the circular shape and may have any other suitable contour. A peripheral region may e.g. be bent concentrically to the central axis of the drive shaft (25). As a result, over a portion of a

Treibwellendrehung a standstill of the applied and acted upon crank mechanism (19) and the adjusting or crankshaft (20) can be achieved. As a result, e.g. a loaded end portion (13,14) for a while to be at rest and remain in the position just taken. This can e.g. be an upper end position in the inclined position or a lower end position in the horizontal position or an intermediate position.

On the other hand, by another training the

High-eccentricity crank or cam disc (27) provides high acceleration and high speed of the crank drive (19) and cam follower thereof

Endbereich or carrier end (13,14) are generated. By means of a corresponding link or curve geometry, a specific desired movement behavior of the applied end region (13, 14) can be achieved. In this case, for example, the end region (13, 14) can be relatively strongly braked for approaching an end position and then held in the end position over a certain rest period, with this being followed by a strong acceleration phase when leaving the end position.

In directly driven crankshafts (20) each having one or more own drive motors (31) or a derived drive connection, the

Manipulation of movement by a targeted control of the respective drive motor (31) within a cycle or a rotation done. This allows resting and

Acceleration phases as well as different ones

Furthermore, it is possible with the drive device (15) shown, the drive power, in particular the

Motor power to the particular requirements of the

Adapt web process. For heavy bonds, e.g. the moment increases. Furthermore, it is possible to run predetermined and programmed driving curves in the various described drive configurations.

Modifications of the shown and described

Embodiments are possible in various ways. In particular, the features of the shown

Embodiments and the above and following

Variants arbitrarily combined with each other and also

be replaced.

In the embodiment of FIGS. 2 and 3, FIGS

Drive shafts (25) each have their own drive motors (29,30). The drive motors (29,30) and the drive shafts (25) can run synchronously. You can alternatively one

Have phase shift. This can be done by a corresponding control of the drive motors (29, 30) can be adjusted. In another and not

illustrated variant, the drive shafts (25) have a common drive motor or a common group of drive motors. The drive transmission

between the drive shafts (25) can via a

Be formed intermediate gear. This is preferably adjustable and may e.g. be designed as a shift transmission with manual or controllable and motorized adjustment. In this way, a phase shift between the drive shafts (25) can be generated.

In the embodiments shown are the

Platinum carrier (11, 12) with its longitudinal axis in

Kettrichtung (32) aligned and arranged in the weft direction side by side in a row. Within the series arrangement, the respective end regions or carrier ends (13, 14) carry out similar strokes due to a similar design of the crank mechanisms (19). In variations to this, the crank mechanisms (19) may be formed differently on a common crankshaft (20) and / or arranged differently. As a result, e.g. acted upon by a crankshaft (20)

End regions or carrier ends (13, 14) in the row

perform different strokes. In addition, e.g. the lower end positions in the series arrangement of

Platinum carriers (11,12) vary. Within one

Row arrangement can be arranged differently high platinum carriers (11,12). As a result, an oblique position in the extension direction of the

Row arrangement result.

In another embodiment, not shown, the platinum carriers (11, 12) are arranged in a so-called knife box. You can hereby e.g. with their end portions or carrier ends (13,14) each with a transverse to

Knife row aligned support beam or support plate be connected. The platinum carrier (11,12) or knife can be aligned in the weft direction. The adjusting means (17,18) can in such a

Embodiment act on the stringers and can raise and lower these and optionally in

Angle the axial direction of the support beams. The

end support beams can in turn take different altitudes in relation to each other. The adjusting means (17,18) can for the support beams one or more crank mechanisms with common or separate

alternatively have a common drive motor of the drive device, e.g. the

Drive transmission from a common drive shaft to the crank mechanisms with a suitable and possibly

adjustable intermediate gear takes place. The crank mechanisms in turn can be as shown in the

Embodiments are designed and adjusted differently, in particular by variations of the cranks (21).

In others, especially linear driving

Drive motors, the adjusting means (17,18) are adjusted accordingly. Instead of a crank mechanism (21), they can have a different connection to the respective end region (13, 14). Furthermore, in a modification of the embodiments, an inclination of the platinum carrier (11,12) at a

Lifting movement can be achieved by another, eg central drive and guide attack on the board carrier (11,12). LIST OF REFERENCE NUMBERS
