EP2009157B1 - Frame connection device for a heald frame - Google Patents

Description

The invention relates to a shank connection device for a heald of a weaving machine.

Weaving machines usually have a plurality of healds, which are formed by a substantially rectangular frame that holds a large number of healds. The heald frames usually each have two, in use, horizontally held shaft rods connected at their ends by vertically oriented side supports. These units are moved vertically up and down by a shaft drive.

Such a hive is eg. The US 6,378,564 B1 refer to. To move the heald vertically, its two side supports are connected at their respective upper end with a push rod. The push rod is connected to the carriage of a vertical guide. The side support of the heald is also connected via a suitable hook to the carriage of the vertical guide.

For a variety of reasons, heald frames must occasionally be removed from the weaving machine and reinserted there. To do this, loosen the connection between the push rod and the side support. This should be as simple as possible and can be done in a few simple steps. On the other hand, the connection must also be safe to produce again.

The JP 9-21030 A discloses a heddle having vertically displaceably guided side supports. The side supports are braced at their upper ends with Befestigungsklötzen. The free threaded upper ends of push rods are inserted into these clamping blocks and screwed by nuts with these. The push rods are guided separately and spaced from the side supports.

A different concept illustrates the utility model DE 91 03 031 U1 , It starts from a weave, which is moved up and down by traction means. The traction means are, for example, formed by ropes. At the upper end of the side support is used for movement and guidance of the heald a traction means which is secured there by means of a clamping device.

Another concept is from the EP 0 520 540 A1 known. This discloses heald frames with hollow side supports, through the interior of each extending a drive rod in the vertical direction. The push rod is provided at its lower end with a screw thread, which is bolted to the side support. At the upper end of the side support an adjusting screw is provided, the end face rests on the front side of the push rod.

The Japanese tested utility model JP 06-38124 Y2 teaches to design a push rod so that it can receive the side support of a heald form-fitting manner. A clasp with clamping screw is used to attach or loosen the heald. The push rod is guided by fixed guides and thus takes over the leadership of the webshaft. A height adjustment of the shaft from above is not possible.

From the DE 10 2004 047 929 B3 It is known to form hollow the side supports of a shaft rod and to guide a drive rod vertically through the cavity of the side support. The drive rod is connected at its lower end with a drive device in connection. At its upper end, it is threaded. On the threaded end of the rod, a threaded piece or a nut is screwed, which is connected to the side support. If the nut is rotatably mounted on the side support, the height of the heald frame can be adjusted by turning the nut.

It is an object of the invention to provide a shank connection device for a heald of a loom, which is simple in construction and safe to handle. In addition, the simplest possible handling should be possible.

This object is achieved with the shaft connection device according to claim 1:

The shank connection device according to the invention includes a vertically positioned side support and a push rod having an upper free end, the push rod being driven vertically up and down in use at its lower end and resting against the side support over most of its length. As a result, the push rod is stabilized and guided by the side support. For example, it may extend for this purpose through a cavity or interior of the side support, wherein it the cavity surrounding the inside of the side support abuts. But it may also be hollow, for example, in cross-section U-shaped and embrace the side support. In both cases, the push rod and the side support embrace each other. They are mutually supportive.

A particularly simple embodiment of the invention results when the push rod has a rectangular cross-section with two flat sides facing away from each other, which bear against two opposite inner sides of the side support, and when the push rod can move along these inner sides oscillating. A certain flexibility of the push rod then allows a flexible deflection of the push rod in the direction of the long narrow sides of its rectangular cross section. On the one hand, therefore, a secure thrust transfer is possible, on the other hand, the push rod can be connected without an intermediate guide to a moving on an arcuate path joint.

For force-transmitting connection between push rod and side support, a clamping device is arranged at the upper end of the side support, preferably above the upper connection of the side support with the shaft rod, which serves to clamp the side support to the upper free end of the push rod. As a result, the heald in question can be hooked into the loom from above. The adjustment means is assigned to the side support. If the side support and push rod are separated from one another, eg to remove the heald from the weaving machine, the adjusting means, for example in the form of a clamping device, remain on the side support.

Slings on the side support and / or the push rod limit the introduction of a heald shaft down into the weaving machine. These slings also allow the height adjustment of the heddle to each other in a range of 0 to 40 mm. For this purpose, the stop means on the side support have a screw which is adjustably mounted against a stop edge or surface of the push rod. The height adjustment of a heald can be adjusted by means of a locking means e.g. be fixed in the form of a lock nut. To facilitate adjustment of the heel height, the side support or push rod may have a scale. Other known adjustment aids, such as measuring devices, templates, etc., can also be used.

For attachment and / or height adjustment of the heald, the operator in question must have access only to the clamps located at the top of the side supports. Once he has tightened the clamping device, a play-free connection between the side support and the push rod is made. No access to parts or elements below the hull is required. This applies both with regard to the replacement of the heald frames and with regard to their height adjustment.

The heald shafts are driven solely by the side supports. On the shaft rods attack no drive elements. This lowers the manufacturing costs.

Preferably, the side support is formed by a sheet metal bending profile, which, for example, represents a U-profile bar whose open side faces the shaft rods. Such a side support can be produced easily and inexpensively. In addition, the shaft rod connections by profile pieces are formed, which protrude from the open interior of the U-shaped profile side support and extend into the interiors of the shaft rods. The push rod may extend longitudinally through the interior of the U-profile bar. It is preferred that the push rod rests at least on the two flat side legs of the U-profile bar and possibly also on his back. The push rod can be formed as a solid profile bar with different cross-sections and, for example, have a rectangular profile. Preferably, it lies against the entire surface of the inner surface of the U-profile bar.

In this case, the side support is preferably engaged with a slide guide. For the push rod no separate guide device must be provided. It is in turn led by the side support.

It is also possible to form the push rod as a U-profile bar, which engages around the side support. In this case, the side support can be formed as a solid profile or as a U-shaped bar. It is preferred, however, to form the upper end of the side support by a solid profile bar on which attaches the clamping device. In this embodiment, the push rod may be engaged with a slide guide. In this case, the push rods take not only the drive but also the guide function for the heald frames.

The clamping device is preferably adapted to tension the side support and the push rod against each other. This is preferably done directly in direct contact without intervening elements. In the simplest case, the power is transmitted by frictional engagement. The side support and the push rod each have a clamping surface. The two clamping surfaces are stretched against each other and produce the frictional connection.

It is also possible to provide each of the side support and the push rod with a toothing, which engage with each other. The clamping device thus provides a positive connection between the push rod and the side support. The teeth allow a height adjustment in stages that correspond to the tooth pitch. This results in a particularly secure power transmission.

The clamping device has a clamping wedge, which is supported on an inclined surface, which is arranged obliquely to the push rod and a tensioning means, e.g. in the form of a screw. By adjusting the clamping means of the clamping wedge moves from its inclined surface led to the push rod and clamps it firmly. The end face of the clamping wedge and the end face of the push rod can each hold means, e.g. Have toothing, caused by the particularly strong connections. As a result, positive and non-positive connections are possible.

Further details of advantageous embodiments of the invention will become apparent from the drawings, the description or from the claims. The description is limited to essential aspects of the invention and other circumstances. The drawing contains further details which the skilled person can resort to as needed.

In FIG. 1 there is illustrated a loom 1 built into a weaving machine, to which a top shaft rod 2 horizontally disposed in use, a bottom shaft 3 parallelly spaced therefrom and two side supports 4, 5 interconnecting the shaft rods 2, 3 at their ends , On the shaft rods 2, 3 Litzentragschienen are held, between which extend in use vertically arranged healds.

The heald 1 is mounted vertically displaceable in corresponding guides 6, 7. The guides 6, 7 may be, for example, sliding guides which support the side supports 4, 5 slidably. The side supports 4, 5 are, for example, designed as hollow profiles. Through their respective inner spaces extending push rods 8, 9, which are driven at their respective lower end 10, 11 vertically or oscillating up and down. Serve in the present embodiment connecting rods 12, 13 which are connected to angle lever 14, 15.

To connect the side support 4 and the push rod 8 is a clamping device 16. To connect the side support 5 and the push rod 9 is a clamping device 17. Both clamping devices 16, 17 are preferably above the upper shaft rod 2 on the respective side support 4, 5 are arranged. This improves their accessibility and facilitates handling. The side support 4, 5 and clamping device 16, 17 are formed substantially mirror-symmetrical to each other. The following description of the clamping device 16 thus applies correspondingly to the clamping device 17th

• Die Seitenstütze 4 ist, wie Figur 4 zeigt, durch einen U-Profilkörper mit zwei Schenkeln 19, 20 und einem sie verbindenden Rücken in Form eines Steges 21 gebildet. Die Schenkel 19, 20 sind zur weiteren Aussteifung an ihren Rändern 22, 23 umgebogen. Die Seitenstütze 4 umschließt einen Innenraum, durch den sich die Schubstange 8 erstreckt. Vorzugsweise ist die Schubstange 8 mit einem geringen Spiel in der Seitenstütze 4 angeordnet, so dass die Schubstange 8 mit der Innenseite der Schenkel 19, 20 jeweils einen relativ engen Spalt definiert. Dadurch ist die Schubstange 8 in der Seitenstütze 4 in Schubstangenlängsrichtung leicht verschiebbar.

The clamping device 16 forms, together with the side support 4 and the push rod 8, a shaft connection device 18, the in FIG. 2 is illustrated in perspective. Their details go from the representation of the Webschafts 1 and its details after the FIGS. 3 to 7 out:

• The side support 4 is how FIG. 4 shows, formed by a U-profile body with two legs 19, 20 and a back connecting them in the form of a web 21. The legs 19, 20 are bent to further stiffening at their edges 22, 23. The side support 4 encloses an interior through which the push rod 8 extends. Preferably, the push rod 8 is arranged with a small clearance in the side support 4, so that the push rod 8 with the inside of the legs 19, 20 each defines a relatively narrow gap. As a result, the push rod 8 in the side support 4 in the push rod longitudinal direction is easily displaced.

The side support 4 is in FIG. 5 separately illustrated. It has for attachment of the shaft rods 2, 3 each have a connection piece 24, 25. The connecting pieces 24, 25 are held between the legs 19, 20 and connected to them by fastening means 46, for example. Welding points. They leave to the web 21 each have a passage 26, 27 free, through which the push rod 8 can extend. In order to facilitate the insertion of the push rod into the passage 26, 27, the connecting pieces 24, 25 may have edges 44, 45 in the form of chamfers.

The push rod 8 is in FIG. 6 separately illustrated. It is formed by a straight rod, which is preferably a rectangular profile ( FIG. 6 b) having. The opposite flat sides of the push rod 8 are connected to the back 49 along edges 47, 48 having the shape of chamfers. Also, the upper end surface 63 of the push rod 8 is connected via a chamfer with the back 49. The insertion of the push rod 8 in the side support 4 in particular in the passage 26, 27 is facilitated by these bevels 47, 48, and by the chamfers 44, 45 of the connecting pieces 24, 25. In use, the rear side 49 of the push rod 8 bears against the inside of the web 21 of the side support 4. The push rod 8 is bounded at one end by the back and at the other end by a narrow side 65. Preferably, the push rod 8 has a constant cross section over its entire length. At its lower end, it may be provided with a connecting element 28 ( Figure 6a, 6c ), to which a separate linear guide 29 can be assigned ( FIG. 3 ). On the connecting element 28 can connect via a suitable joint connection of the connecting rod 12.

At the upper free end of the side support 4, the clamping device 16 is arranged ( Figure 7a ). The clamping device 16 has a cuboidal insert 50 preferably made of a metallic material. This insert 50 is between the two legs 19, 20 of the side support 4 with a known fastening means 46 (FIG. FIG. 5 ) held firmly. The insert 50 may preferably have a threaded bore 51 for receiving a tensioning means 30. The clamping means 30 may be formed in the form of a screw. The clamping device 16 also includes a wedge piece 54, which is movably held between the two legs 19, 20 of the side support 4. In this case, the two flat sides of the wedge piece 54 may be in contact with the side surfaces 19, 20. The wedge piece 54 has a wedge-shaped end 57 on its end surface facing away from the clamping means 30. In the relaxed state, this wedge-shaped end can rest against a complementary abutment surface 58 of the connection piece 24 or stand at a small distance therefrom. The wedge piece 54 is through a Spring element 55, which on the end faces of the bent legs 19, 20, the edges 22, 23 held slidably. The spring element 55 may be formed in the form of a leaf spring and is connected by a holding means 56 with the wedge piece 54. In the relaxed state ( Figure 7a ), the first narrow side 59 of the wedge piece 54 project beyond the opening of the U-shaped side support 4, it can also be flush with this. The second narrow side 61 of the wedge piece 54 is oriented in the direction of the narrow side 65 of the push rod 8 out. If the clamping means 30 is adjusted, so that the in Figure 7a and 7b decreases the specified distance Y, the wedge piece 54 moves due to the interaction of its wedge-shaped end 57 with the contact surface 58 of the fitting 24 which is fixedly connected to the shaft rod 2, transverse to the longitudinal direction of the side support 4 on the push rod 8. The clamping means 30 can be adjusted so far that the push rod 8 between the second narrow side 61 of the wedge piece 54 and the web 21 of the side support 4 is firmly clamped ( FIG. 7b ). As a result, the drive of the heald 1 is ensured via the push rod 8 and the side support 4. By the displacement of the wedge piece 54 in the direction of the push rod 8, the spring means 55 is tensioned. This creates a force F ( FIG. 7b ), which acts with its largest proportion transversely to the longitudinal direction of the side support 4 and against the displacement direction of the wedge piece 54. Due to this force, the wedge piece 54 moves to its original position ( Figure 7a ) when the tensioning means 30 is opened.

FIG. 8a and FIG. 8b show another embodiment of the clamping device 16. Except for the second narrow side 61 of the clamping piece 54 and this opposite narrow side 65 of the push rod 8 are the clamping devices according to the FIGS. 7 and 8th identical. The description applies by reference to the same reference numerals. In order to enable a positive connection of the clamping piece 54 with the push rod 8, that is the heald shaft 1 with the shaft connection device 18, the second narrow side 61 of the clamping piece 54 and the opposite narrow side 65 of the push rod 8 form-fitting means, for example in the form of a toothing 35 , This makes a particularly strong, stable connection possible. FIG. 8a shows the clamping device 16 in the relaxed state while FIG. 8b the clamping device 16 in the clamped state shows.

FIG. 9a and FIG. 9b show another embodiment of the clamping device 16. Except for the second narrow side 61 of the clamping piece 54 and this opposite narrow side 65 of the push rod 8, the clamping devices according to FIG. 7 and 9 identical. The description applies by reference to the same reference numerals. In order to produce the positive connection of the clamping piece 54 with the push rod 8, the second narrow side 61 of the clamping piece 54 is arranged at an acute angle α to the back of the side support 4. The narrow side 65 of the push rod 8 is arranged complementary to the narrow side 61. If the distance y is reduced by the adjustment of the tensioning means 30, a clamping device 16 acts according to FIG FIG. 9 in that the push rod 8 frictionally rests up against an adjusting means 60. FIG. 9a shows the clamping device 16 in the relaxed state while FIG. 9b the clamping device 16 in the clamped state shows.

The clamping device 16 may have, in addition to the clamping means 30, a stop means or adjusting means, for example in the form of an adjusting means 60. As FIG. 7 shows, For example, the adjusting means 60 may be designed in the form of a screw and is held adjustably in the longitudinal direction of the push rod 8. For this purpose, the insert 50 may have a second threaded bore 52, which receives the adjusting means 60. To adjust the adjusting means 60, a known device, such as a hexagon socket can be used at one end. At the other end opposite the adjusting device of the adjusting means 60, the adjusting means 60 has a contact surface 62. This system 62 cooperates with the end face 63 of the push rod 8. To secure the adjusting means 60, a holding means 64 can be found, for example in the form of a lock nut application.

FIG. 10 shows another embodiment of the clamping device 16. The insert 50 'of the clamping device 16 has a simplified adjusting or adjusting means 60 in the form of a stop surface 66. This adjustment is held stationary. The stop surface 66 is opposite the end face 63 of the push rod 8. The side support 4 has a recess 68 in the end region. In this recess 68, a spacing means 67 can engage to set the position of the heald 1 with respect to the push rod 8. This allows the setting of multiple healds 1 a loom in a quick easy way. To set different heights of multiple healds 1 spacers 67 can be used with different heights application. Otherwise applies to the embodiment according to FIG. 10 at the same reference numerals, the description accordingly.

It is also possible that on the push rod 8, the adjusting means 60 is formed. Then the adjusting means is not part of the clamping device 16. The adjusting means is, for example, in the form of a projection 75 at the lower end of Push rod 8 like FIG. 6c shows trained. The projection 75 may be in the form of a pin which fits tightly into a corresponding bore in the push rod 8. The projection 75 may also be seamless, integrally formed on the push rod 8. An adjusting means designed in this way prevents the side support 4 from falling down over the push rod 8 of the heald 1 when the heald 1 is inserted. Thus, it is also avoided that in the connection of the heald shaft 1 with the drive device of the weaving machine of the heald 1 comes into contact with the connecting element 28.

• Der Webschaft 1 ist in Betrieb, wie in Figur 3 veranschaulicht, mit seiner Antriebseinrichtung verbunden. Dazu ist der Webschaft 1 von oben her über die Schubstange 8 geschoben und auf der gewünschten Höhe durch Anziehen des Spannmittels 30 arretiert. Jede Antriebsbewegung der Schubstange 8 wird somit auf den Webschaft 1 übertragen. Die Schubstange 8 ist zwischen den Schenkeln 19, 20 gefasst. Sie kann, wenn sie Schubkräfte überträgt, keine seitliche Ausweichbewegung durchführen. Die Antriebsbewegung wird somit sicher und spielfrei auf den Webschaft 1 übertragen.

The shaft connection device 18 described so far works as follows:

• The weave 1 is in operation, as in FIG. 3 illustrated connected to its drive device. For this purpose, the heald 1 is pushed from above over the push rod 8 and locked at the desired height by tightening the clamping means 30. Each drive movement of the push rod 8 is thus transmitted to the heald 1. The push rod 8 is caught between the legs 19, 20. It can, if it transmits shear forces, perform no lateral evasive movement. The drive movement is thus transmitted safely and without play on the heald shaft 1.

If the heald 1 are adjusted in height, the clamping means 30 is released and the side support 4 with respect to the push rod 8 moved up or down. The displacement can be effected by means of the adjusting means 60. Once the desired position has been reached, the clamping device 30 is tightened again. The same applies to the clamping device 17 in the essential features of the clamping device 16 corresponds. Thus, the above description applies accordingly. For easy adjustment of the height of the heald 1, the side support 4, 5 and or the push bar 8, 9 marks (not shown), for example. In the form of a scale.

To replace the heald 1, the clamping means 30 of the clamping device 16 and the clamping means of the clamping device 17 are released. Then, the heald 1 can be deducted from the push rod 8 (and 9) upwards, as it FIG. 11 shows. Thereafter, the same heald 1 or another heald 1 on the push rod 8 (and 9) pushed back and locked in the desired height. When replacing or separating a heald shaft 1 from the drive device or when adjusting the height of a heald 1 with a shank connection device 18 according to the invention, no further parts are to be released or displaced beyond the opening of the tensioning means 30, neither in the longitudinal direction of the side support 4 5 still in the longitudinal direction of a shaft rod 2, 3. The guides 6, 7, 29 may be held stationary. Nevertheless, the heald 1 can be replaced.

It should be understood that the foregoing and following description of the shank terminal 18 relates equally to the shank terminal of the side support 5. In that regard, a tightening of the clamping device 16 at the same time means a tightening of the clamping device 17. A release of the clamping device 16 means at the same time a release of the clamping device 17th

FIG. 11 illustrates the heddle 1 when it is separated from the push rod 8. He can now on the Push rod 8 are put back by his side support 4 is pushed over the push rod 8. It can then be locked in a desired working height, as has been described above. As can be seen, the height adjustment of the heald 1 and the same does not require access to the space below the heald 1. The handling of the shaft connection device 18 according to the invention is therefore particularly comfortable.

FIG. 12 It illustrates a modified embodiment of the heald 1. It differs from the above described heald shaft 1 by the elimination of the connecting element 28, the linear guide 29 and the connecting rod 12. Here, the push rod 8 is directly connected to the angle lever 14. The push rod 8 has a certain flexibility or resilient compliance, by which it can spring in the direction of the shaft rod 3 and the web 21 of the side support 4. Thus, the push rod 8 at its lower pivot point 31 of the pivotal movement of the angle lever 14 follow pendulum. This in particular when the push rod 8 in the side support 4 can perform a pivoting movement. It is then the entire length of the clamping device 16 to the pivot point 31 for flexible deflection and pivoting of the push rod 8 available. For this purpose, in particular the lower passage 27 is measured perpendicular to the web 21, further than the width of the push rod 8 measured in the same direction. The width of the passage 26 (FIG. FIG. 5 ) is preferably larger than the width of the push rod 8 to be measured in the same direction.

Another embodiment of the invention is in the FIGS. 13 to 17 illustrated. The peculiarity of this embodiment is that both the side support 4 ( FIG. 15 ) as well as the push rod 8 ( FIG. 14 ) are formed as U-profiles. This results in a particularly rigid design of the push rod 8 as well as the side support 4. In this embodiment, the push rod 8 overlaps with their legs 70, 71, the legs 19, 20 of the side support 4. The side support 4 is disposed within the push rod 8, as in particular Figure 17a evident. The push rod 8 is how FIG. 14 shows, provided at its upper end with a solid profile bar 39 which extends beyond its upper end. The solid profile bar 39 is for example. Welded to the push rod 8 and forms the upper end thereof. It may, for example, have a rectangular cross-section. As FIG. 13 illustrated, the side support 4 is provided at its upper end with a U-shaped clamping collar 40. This projects beyond the back or web 21 of the side support 4 and its two legs 72, 73 are connected to the legs 19, 20 of the side support 4.
