Background technique

A drive system of the above-mentioned form is known from WO 99/04075.

Another drive system for heald frames is known from EP 742298 A1. In a first exemplary embodiment, a drive lever driven by a driver drives a coupling rod, one end of which is connected to the drive lever via an adjustment unit and its other end engages on a first lever. This lever is connected to the second lever via a connecting rod, for example at the point of articulation of the coupling lever. The two levers are connected to the heald frames by transfer rods. In the second embodiment of EP 742298 A1, the coupling rod extends substantially on the extension of the connecting rod, which connects the levers to each other, which are each connected to a heald frame.

Contents of the invention

The object of the present invention is to provide a drive system of the type described above which can be operated at high weaving speeds.

This object is achieved in that the control lever and at least one further lever are arranged in a housing which is fastened to a loom frame.

The drive system according to the invention can be designed very compactly and also very rigidly, so that it is only subjected to very slight vibrations. This makes it possible to run at high weaving speeds. The drive system according to the invention requires relatively little space for the weaving machine, so that, for example, a weft preparation system can be placed on the drive system. The operation of the drive system is essentially independent of the alternating forces acting on the drive system and also independent of the alternating temperature.

In the design solution of the present invention, it is stipulated that the housing is composed of a first sub-housing and a second sub-housing, the control lever is supported in the first sub-housing, and at least another sub-housing is supported in the second sub-housing. a lever. The control lever and its bearings are subjected to relatively high forces, which are transmitted via the shaft into the housing. The housing that accommodates the control lever shaft must therefore be of relatively solid design. In an assembled housing, it is sufficient only for the part housing which accommodates the control lever to be particularly robust.

In a further development of the invention it is provided that the housing or sub-housing and the control lever are provided with a fastening means for mounting on a side part of the loom frame. Therefore, the active force transmitted to the sub-housing by the control lever shaft is directly transmitted to the inside of the loom frame. It is advantageous here if the fastening means comprise elastic elements. The transmission of vibrations and shocks from the frame to the drive system of the shedding system and the transmission of vibrations and shocks from the drive system to the frame of the weaving machine can thereby be reduced.

In a further development of the invention, the partial housing in which at least one further lever is mounted is fastened to the partial housing of the control lever, thereby enabling simple assembly. In order to connect the two partial housings to one another, that is to say that the axis of the control lever is precisely aligned with the axis of the other lever, it is provided in a further development of the invention that the two partial housings have reference surfaces facing each other , which preferably each extend parallel to the axis arranged therein.

In a preferred embodiment of the invention it is provided that the control lever has an upwardly protruding lever arm starting from its axis, which is connected to the drive lever via a coupling mechanism, wherein the coupling mechanism preferably comprises a coupling rod and a regulating unit. This configuration facilitates the accessibility of the drive system, in particular of the coupling mechanism.

In a further refinement of the invention it is provided that the shaft of the control lever is arranged on an end face of the partial housing which faces the second partial housing. This makes it possible on the one hand to arrange the control lever next to the opening system. Furthermore, this arrangement makes it possible to arrange a lubricating system with lubricating oil lines and lubricating oil nozzles for the bearings of the control lever, so that these bearings can be well lubricated and also cooled. Good lubrication and cooling of the bearing on the shaft is advantageous because this bearing is subjected to relatively high forces. This arrangement also enables simple mounting and dismounting of the shaft.

In one embodiment of the invention, the drive lever is arranged in the same partial housing in which the control lever is supported.

In a variant embodiment, the drive lever is arranged in another housing part which is arranged on the side of the housing part of the control lever opposite the second housing part. In an advantageous further development, it is provided that the partial housing of the control lever has a reference surface which faces a reference surface of the partial housing of the drive lever, said reference surface preferably being arranged parallel to the associated partial housing. Shaft extension of the control lever and drive lever in the body. Due to the reference plane, the two partial housings can be positioned precisely relative to each other and assembled into a unit. As a result, the axis of the control lever and the axis of the drive lever can be aligned parallel to each other and the control lever and the drive lever can be precisely centered relative to each other. This alignment is also maintained across effective force changes and temperature changes. A seal is preferably provided between the reference surfaces, whereby oil, in particular lubricating oil, can be prevented from penetrating between the reference surfaces.

According to a preferred embodiment, the control lever is connected to the drive lever via a coupling system, in particular via a coupling rod. In this case, the coupling lever is preferably articulated on an upwardly protruding lever arm of the control lever and is connected to the drive lever via the adjusting unit. This arrangement results in a relatively short and rigid coupling rod, which can thus be operated at high weaving speeds. The connection of the coupling lever to the upwardly protruding lever arm of the control lever and the connection of the adjustment unit to the drive lever enables the adjustment unit to be placed in a position with good contact and good visibility. Adjustment can thus be easily carried out by means of the adjustment unit. The regulating unit is in this case located above the oil sump in the housing, so that the operator can also easily operate the regulating unit with relatively warm oil.

In an advantageous embodiment, it is provided that the axis of the drive lever, the point of action of the adjusting unit on the drive lever, the hinge point of the coupling lever on the control lever and the axis of the control lever lie approximately at the inflection points of a rectangle. The advantage of this arrangement is that the position at which the coupling rod is connected to the drive lever via the adjustment unit causes the movement curve of the control lever to be changed only relatively slightly relative to the movement curve of the drive lever, so that the opening system passes through one of the adjustment units. The so-called rapid adjustment has only a slight influence on the asymmetry of the movement curve of the control lever or an asymmetric process.

According to a preferred embodiment, the control lever is connected to the second lever via a connection system, in particular via a connecting rod. Since the connecting rod and the control lever and the second lever can be selected to be relatively long, possible deviations between the orientation of the control lever and the second lever can be compensated for. The connecting rod can be designed to be less rigid than the coupling rod, since the forces transmitted to the connecting rod are generally only a fraction of the forces that the coupling rod has to transmit.

In one embodiment of the invention at least one intermediate wall is located between the partial housings. As a result, the oil, in particular the lubricating oil located in the subhousings, can be separated from one another. This makes it possible, for example, for lubricating oil to be present in one housing sub-housing of the control lever, but not in the other housing sub-housing. According to one embodiment, the intermediate wall simultaneously serves as a seal between the partial housings. According to an exemplary embodiment of the invention, there are two intermediate walls between the partial housings, ie each partial housing has an intermediate wall protruding from the bottom. As a result, the partial housings can be separated from one another without oil, in particular lubricating oil, escaping. As a result, one partial housing can be dismantled and replaced by another, without the lubricating oil escaping.

In a further development of the invention, a pressure oil line is connected to the shaft of the control lever and/or the shaft of the drive lever and/or the shaft of another lever, and the shaft is equipped with pressure oil which is guided to the bearing aisle. Through this structure, the pressure oil can be directly pumped to the bearing, and then the oil can flow to the bearing and can drip into the sub-housing. In a development, it is provided that the pressure oil channels of the lever mounted on the shaft are connected to the pressure oil channels of the shaft, which lead to the joint point between the lever and the connecting rod. This enables pressure oil lubrication to be effective at all bearing points.

In a further development of the invention it is provided that a preferably detachable mount for the opening system guide is provided on the housing. As a result, the shedding system, for example the side guides of the loom bars, can also be arranged independently of the loom frame. The drive system according to the invention can form a module or a structural unit, which can be fastened to the frame of the weaving machine. Such a structural unit can be easily mounted on the loom and detached from the loom again.

In a further development of the invention it is provided that the control lever and at least one lever are arranged in a housing, the upper side of which is equipped with vertical guides for the coupling parts, which are connected via the transmission rod to the control lever and at least one other A lever connection and they can be coupled with the opening system.

In a further development of the invention it is provided that the drive lever, the control lever and the further lever and preferably also vertical guides for a plurality of opening systems arranged one behind the other are accommodated in a common housing.

Detailed ways

The drive system for the opening system 2 shown in FIGS. 1 to 5 has a control lever 4 mounted pivotably on a shaft 3 . The control lever 4 has a first lever arm projecting upwards from the shaft 3 , which is connected at an articulation point 5 to a drive lever 6 . The control lever 4 also has a second lever arm projecting downwards from the shaft 3 , which is connected at an articulation point 7 to a lever 9 pivotable about an axis 8 parallel to the axis 3 . The control lever 4 is arranged via its shaft 3 in a partial housing 10 which is fastened to a frame 11 of a weaving machine which has two side parts 12 , 13 . The articulation point 5 is preferably located opposite the articulation point 7 substantially on the diameter of the shaft 3 .

The control lever 4 has a third lever arm which projects substantially horizontally at the level of the shaft 3 . This lever arm is connected at an articulation point 15 to a transmission system, for example a transmission rod 16 . The coupling part 18 is connected to a shedding system 2 , in particular a coupling rod 19 of a heald frame 14 . The other lever 9 likewise has a substantially horizontally oriented lever arm, which is connected via a corresponding joint point 15 to a transmission rod 16 which is connected to a coupling part 18 on a joint point 17, The coupling part accommodates a coupling rod 19 of the heald frame 14 . The connection between the coupling part 18 and the coupling rod 19 is formed, for example, as is known from EP 520 540 A1.

The drive lever 6 is connected to the control lever via a coupling mechanism, ie via a coupling rod 20 and an adjusting unit 21 . The further lever 9 is connected to the control lever 14 via a connection system, for example a connecting rod 22 . The coupling rod 20 is connected to the driving lever 6 through an adjustment unit 21 , which can realize the adjustment of the relative position of the coupling rod 20 and the driving lever 6 . The adjusting unit 21 is easily accessible since it is located in the drive system 1 from above. The drive lever 6 is mounted pivotably on a shaft 27 . It is driven by a driver 23 . This drive 23 can be, for example, an eccentric drive, a cam drive or a lever mechanism.

The articulation points 5, 7, 15 and 17 comprise bearings such as ball bearings or roller bearings, which are respectively arranged on journals. For example, the journal can be located on the control lever 4 , while a bearing is located on the coupling rod 20 , the connecting rod 22 and the transmission rod 16 . The coupling part 18 can have journals which cooperate with a bearing of the coupling rod 16 .

The partial housing 10 accommodates the control lever 4 and its shaft 3 , on which is mounted a second partial housing 24 which accommodates the shaft 8 and the second lever 9 as well as the connecting rod 22 . The housing lower part of this partial housing 24 is a U-shaped profile which is beaded, for example, from sheet metal. This U-shaped profile can be provided with a recess or groove in the lower part, into which oil can be introduced. The shaft 3 of the control lever 4 is arranged on the end face 25 of the partial housing 10 which faces the second partial housing 24 . The housing upper part of the partial housing 24 is formed, for example, by a detachable cover plate, which accommodates the vertical guide 26 in which the coupling part 18 is guided linearly.

The shaft 27 of the drive lever 6 is located in a third housing part 28 which is fastened to the housing part 10 of the control lever 4 . The shaft 27 of the drive lever 6, the hinge point 5 of the coupling rod 20 on the control lever 4 and the shaft 3 of the control lever 4 are located substantially at the inflection points of a rectangle.

The partial housing 10 of the exemplary embodiment according to FIGS. 1 to 5 has two side walls 29 and 30 and a base 31 . A transversely extending flange is provided at the end of the partial housing 10 . As shown in FIGS. 2 and 4 , the third sub-housing 28 is fixed on the first sub-housing 10 by bolts 32 . The first subhousing 10 is fastened to the side part 12 of the loom frame 11 by fastening means, for example by bolts 33 . The second sub-housing 24 is fixed on the first sub-housing 10 by bolts 34 . As shown in FIG. 2 a , a fastening mechanism is provided between the partial housing 10 and the side part 12 with an at least partially elastic connection 69 . Elastic parts 71, 72, such as rubber rings or helical springs or coil spring or similar. Through this elastic connection 69 , when the sub-housing is placed on the main frame 11 , the sub-housing 10 can move slightly relative to the frame 11 . This movement is especially possible in the longitudinal direction of the screw 33 . As a result, the forces and vibrations of the frame 11 are transmitted to a small extent to the partial housing 10 and thus to the entire structural unit, which consists of the partial housing 10, the partial housing 28 and the partial housing 24 . The forces and vibrations of this structural unit are likewise transmitted to the machine frame 11 to a lesser extent. The relative positions of the shaft 3 of the control lever 4 and the shaft 27 of the drive lever 6 and the shaft 8 of the other lever 9 are produced during the relative movement between the structural unit and the machine frame 11 .

Furthermore, as schematically shown in FIG. 2 , a plurality of drive systems 1 according to the invention are arranged within the same housing, which is composed of subhousings 10 , 24 and 28 . The control levers 4 of all drive systems 1 are mounted on a common shaft 3 . The levers 9 are likewise mounted on a common shaft 8 . A common shaft 27 is also assigned to the drive levers 6 of all drive systems 1 .

The partial housing 10 and the partial housing 28 are covered from above by a cover plate 35 which seals the two partial housings 10 , 28 in a dust-tight manner. As can also be seen, for example, from FIG. 1 , this cover also extends through the side part 12 as far as the upper part of the partial housing 24 .

The partial housing 28 together with the drive 23 and the drive lever 6 can be detached from the partial housing 10 and replaced by another partial housing. The other sub-housing can also include another drive, that is, a sub-housing 28 can optionally be connected to the sub-housing 10, which has an eccentric drive, a cam drive, a lever mechanism or an other drive. form.

Because only said sub-housing 10 is placed on the side part 12 of the loom, the sub-housings 24 and 28 on the sub-housing 10 can only affect the shaft 3, drive of the control lever 4 by force to a slight extent. The relative position of the shaft 27 of the lever 6 and the shaft 8 of the second lever 9, for example due to the force generated by the impact movement of a fabric box on the side part 12 of the weaving machine.

As shown in FIG. 3 , the partial housing 10 has a reference surface 36 and the partial housing 24 has a reference surface 37 . These reference surfaces 36, 37 face each other when the partial housings 10 and 24 are fixed to each other. The reference plane 36 extends parallel to the axis 3 of the control lever 4 . When the reference surfaces 36 , 37 bear against each other, the axes 3 and 8 therefore run parallel to each other. In order to be able to achieve a seal between the two partial housings 10 and 24 , a seal 38 is inserted between the reference surfaces 36 and 37 . This seal 38 consists, for example, of a thin strip having the outline of the reference surfaces 36 , 37 . The reference planes 36 , 37 extend perpendicular to the longitudinal direction A of the drive system 1 shown in FIG. 2 .

The shaft 3 for the control lever is a shaft 39 which is equipped with a clamping system 40 on the end face 25 of the partial housing 10 . The control lever 4 is supported on this shaft 39 via a ball bearing or a roller bearing. As shown in particular in FIG. 1 , for the shaft 3 there is a lubrication system 41 with oil lines 42 and nozzles 43 which are aligned with the shaft 3 of the control lever.

The partial housing 10 has a reference surface 44 which corresponds to a reference surface 45 of the partial housing 28 . The two reference surfaces 44 , 45 face each other in the assembled state. The reference plane 44 extends parallel to the axis 3 of the control lever 4 . The reference plane 45 extends parallel to the axis 27 of the drive lever 6 . When the reference surfaces 44 , 45 bear against each other, it is ensured that the shaft 3 and the shaft 27 are aligned parallel to each other. In order to achieve a seal between the two partial housings 10 and 28 , between the reference surfaces 44 , 45 there is a seal 46 which likewise is a thin strip which follows the contour of the reference surfaces. The reference planes 44 , 45 also extend perpendicular to the longitudinal direction A of the drive system 1 shown in FIG. 2 .

As shown in FIG. 5 , first a structural group consisting of the partial housing 10 and the partial housing 28 is preassembled and fastened to the side part 12 . Before the partial housing 10 is placed on the side part 12 , the partial housing 24 is fastened to the partial housing 10 . However, it is also possible to fasten the partial housing 24 to the partial housing 10 after the fastening of the partial housing 10 to the side part 12 . As can be seen in particular from FIG. 1 , the housing subhousings 10 , 24 and 28 shown form a housing which serves as a storage container for oil 47 , ie lubricating oil. The level of the lubricating oil can be selected in a suitable manner.

In the exemplary embodiment according to FIG. 6 there are intermediate walls 48 , 49 between the partial housing 10 and the partial housing 24 , which protrude from the bottom toward the middle. Said intermediate walls 48, 49 are located close to the reference planes 36, 37, respectively. The intermediate walls 48 , 49 are relatively low in height so that they do not enter the range of movement of the control lever 4 . Between the partial housing 10 and the partial housing 28 are likewise provided two intermediate walls 50 , 51 which likewise lie close to the respective reference plane 44 , 45 . As can be seen from FIG. 6 , different heights of the oil 47 level can thus be selected in the individual housing subhousings 10 , 24 , 28 . The oil level is high in the partial housing 28 , relatively low in the partial housing 24 and very low in the partial housing 10 . The intermediate walls 48 , 49 or 50 , 51 can also assume a sealing function. The intermediate walls 48 and 50 of the partial housing 10 can also be withdrawn if an oil level is not desired in the partial housing 10 . The use of an intermediate wall provides the possibility of disassembling the sub-housings 28 or 24 without the oil flowing out.

In the exemplary embodiment according to FIGS. 7 and 8 , the drive lever 6 is mounted in a partial housing 52 in which the control lever 4 is also mounted. The partial housing 52 is fastened to a side part 12 of the loom frame 11 , as already described with the aid of the fastening of the partial housing 10 . The partial housing 52 can be equipped with an intermediate wall 48 in a manner corresponding to the partial housing 10 . In the exemplary embodiment according to FIGS. 7 and 8 , a third lever 53 is additionally provided for the second lever 9 pivotable about an axis 8 , which is pivotable about an axis 54 and which is likewise articulated on the connecting rod 22 . The shafts 8 and 54 are arranged in the partial housing 24 , which is fastened to the partial housing 52 .

In the exemplary embodiment according to FIG. 9 a common housing is used for the drive lever 6 , the control lever 4 and the second lever 9 or 53 , in which the associated shafts 3 , 27 , 8 and 54 are arranged. This housing 56 is likewise fastened to a side part 12 of the loom frame. The fastening can take place via flanges in the manner described for the partial housing 10 .

In the exemplary embodiment according to FIGS. 7 to 9 , the coupling lever 20 is also arranged from above on the partial housing 52 or the housing 56 , so that the adjustment unit 21 is respectively accessible. In the exemplary embodiment according to FIG. 9 the coupling rods are split and consist of link coupling rods 57 , 58 . The linkage between the control lever 4 and the levers 9, 53 is likewise divided into two linkages 59, 60, which are connected to each other. Spray nozzles 55 are assigned to the individual bearing points, via which nozzles lubricating oil can be sprayed onto the relevant bearing points. In this exemplary embodiment, the joint point 5 and the joint point 7 are at least approximately diametrically opposite with respect to the axis 3 of the control lever 4 .

In the exemplary embodiment according to FIG. 10 a common partial housing 61 is used for the shaft 3 of the control lever 4 and the shafts 8 and 54 of the other levers 9 and 53 . A second partial housing 62 accommodates the drive 23 and the shaft 27 of the drive lever 6 . The connection between the components of the drive system 1 is realized at the coupling rod between the control lever 4 and the drive lever 6 , ie by the connection of the two coupling rods 57 , 58 . The two sub-housings 61 , 62 can each be fastened to their own side parts 12 of the machine frame 11 . However, it is also possible to fasten only the partial housing 61 to the side parts and to fasten the partial housing 62 to this partial housing 61 .

The two partial housings are equipped with intermediate walls 63 , 64 for adjusting different oil levels in the partial housings 61 , 62 .

Of course, the parts arranged between the control lever 4 and the further levers 9 and 53 and a shedding system 2 , for example a heald frame 14 do not have to have the shape shown in FIGS. 1 to 10 . As shown in FIG. 11 , a coupling element 66 is guided in each case in the vertical guide 26 , which is coupled to a hook 67 which is fastened to the upper end of the heald frame 14 . The coupling part 66 is provided with a thickened portion 68 which engages in the hook 67 .

In the exemplary embodiment according to FIG. 12 , spray nozzles 55 are provided for all bearing positions and connection points, which correspond to the nozzles 43 in FIG. 1 and are supplied with oil via the oil supply line. For the exemplary embodiment according to FIG. 12 it is also provided that guides 73 , 74 for the heald frames 14 are provided on the partial housing 24 . In this exemplary embodiment, the guide 73 can be moved out and back again corresponding to the direction of the arrow, so that the heald frame 14 can be exchanged. The guides 73 , 74 are seated on the top side of the partial housing 24 via supports 75 , 76 . These supports 75, 76 are detachably connected in the sub-housing 24, so they are placed on the loom after the sub-housing 24 has been placed on the weaving machine.

In the exemplary embodiment according to FIG. 13 it is provided that the shafts 3 , 8 , 27 and the hinges at the connection points between the lever and the connecting rod are supplied with pressurized oil. To this end, pressurized oil lines 77 , 78 , 79 indicated by dotted lines lead from a schematically indicated pressurized oil source 80 , for example an oil pump, to the connections of the shafts 3 , 8 and 27 . These shafts have drain holes at the bearings, whereby the bearings are supplied with oil which then drips down into the sub-housings. Inside the levers and connecting rods there is an oil channel 81 which branches off from the outlet holes of the shafts 3, 8, 27 and leads to the joints of the articulation points. Further oil channels 82 branch off from the outlet bores of the shafts 5 , 15 .

The drive system 1 according to the invention can form a structural unit which can be fastened to the frame 11 of the loom. The design of the drive system 11 enables the formation of a compact structural unit which can be easily assembled or also replaced. The size of the sub-housing can be selected as appropriate.

The partial housing 10 or the partial housing 52 can of course also be placed on the side part 13 of the loom frame 11 . Because the drive system 1 according to the invention only needs a relatively small construction height, the yarn supply mechanism for the weft thread can be arranged above the drive system 1 either on the side part 12 or on the side part 13 of the loom frame 11 .

The drive system according to the invention can be installed in all types of weaving machines, such as air nozzle looms, rapier looms, rapier protection looms, water jet looms, projectile looms and others. The drive system according to the invention can also be retrofitted on already existing weaving machines.

In an embodiment not shown, the vertical guides are fastened to the side parts 12 , 13 of the machine frame 11 . In another embodiment, the shaft 8 of the lever 9 or the shaft 54 of the lever 53 is fixed on the frame 11 . In another embodiment, the partial housing 24 is replaced by an open support part which extends between the side parts of the connecting rod.

The invention is not restricted to the exemplary embodiment of the drive system described by way of example and shown in the drawings. In particular combinations of the individual exemplary embodiments are possible. The scope of protection is determined only by the features of the claims and their equivalents.
