专利说明:
1 The invention relates to the construction of a rotary heddle shunt carriage, in which a motion transducer — an eccentric — is connected and disconnected according to a predetermined program with the shaft making an intermittent rotation. A rotary conveyor carriage of a weaving machine is known, comprising a switching clutch installed according to the number of shafts of the machine tool, each of which includes a connecting rod connected to the shade of the machine and a hinge mounted on the periphery of the ex- centric ring mounted on the drive shaft, which is installed with an intermittent rotation and the head of the hub is mounted on the periphery of the eccentric ring. , mounted in the groove of the eccentric ring with the possibility of alternate entry into the recesses of the drive shaft and connecting rod for engagement with them, cam means for fixing with single wedge ll. However, at high speeds when shutting off, the connecting wedge does not manage to move from the recess of the drive shaft to the recess of the connecting rod under the action of the spring, since a change in the speed of the drive shaft causes dynamic loads pressing the wedge against the supporting surfaces with such a force that the spring force is insufficient to provide switching. In this case, the speed capabilities of the carriage are limited. The aim of the invention is to increase the speed capabilities of the carriage by increasing the reliability of the switching clutch. The goal is achieved by the fact that in a rotary helix carriage, containing a switching clutch installed according to the number of the machine tool, each of which includes a connecting rod connected to the machine shaft and hinged at the periphery of the eccentric ring mounted on the drive shaft, installed with the possibility of moving. , connective wedge mounted in the groove of the eccentric ring with the possibility of alternately entering the drive shaft and connecting rod to the coupling and the coolant kovye means for fixing the connector 5. g wedge, eccentric ring dodyul-. relatively has a radial groove and a thrust wedge placed in this groove with the possibility of sliding, the working areas of which are facing the drive shaft and the connecting rod have closed planes with an angle of inclination to the sliding direction of the wedge smaller than the friction angle and guide planes whose angle of inclination to the direction the wedge slides are larger than the friction angle, and the drive shaft and the connecting rod additionally have at least one notch for the stop wedge, whose profile corresponds to the profile of the working sections of the stop wedge, and the width of each of The opening is less than the width of the connecting wedge. The locking plane of the working section of the thrust wedge facing the drive shaft and the corresponding recess plane of the drive shaft are parallel to the middle radial beam located between the notches for the connecting and thrust wedges. The recess for the retaining wedge and the working sections of the retaining wedge facing them are rounded edges. The eccentric ring has a latch installed at its end, spring-loaded in the direction perpendicular to the abutment wedge, and the resistant wedge has a recess for interacting with the latch. FIG. 1 shows a shift clutch of a helix carriage, side view, in FIG. 2 is the same, section A-A in FIG. 1 in FIG. 3 — Switching body (switching ring) end view with groove; in FIG. 4 placement of the connecting and thrust wedges in the grooves of the drive shaft; in fig. 5 - execution of the connecting wedge with the slot; in fig. 6-12 shows a switching clutch without a switching ring with different positions of wedges} in FIG. 13, displacing the stop wedge from the recess for the connecting wedge. The shift clutch of the heald carriage (Fig. 1-4) has a propeller shaft 1, is installed with the possibility of intermittent rotation (with stopping or deceleration every 180). On the drive shaft, the bearing ring 2 is fixed with the help of a key 3. On the ring 2, subtype 31 The roller bearing 4p placed an eccentric ring 5, on the periphery of which, by means of a roller bearing 6, a connecting rod 7 is pivotally mounted. A ha 8 of the connecting rod 7 is pivotally connected with a lever 9, which is kinematically connected with a weaving machine. In order to couple the eccentric ring 5 with the drive shaft 1 or with the connecting rod 7, there is a connecting wedge 10, which is installed in the groove of the eccentric ring 5 with the ability to interact with the recess 11 connected to the drive shaft 1 or with the recess 12 connected with the cross-link 7.. The connecting rod 7 has cam means 13, and the drive shaft 1 has cam means 14 for fixing the connecting wedge 10 in the recess 11 of the drive shaft 1 and the recess 12 of the crank 7. There is a switching element 15 for controlling the connecting wedge 10 (Fig. 3). Regardless of the connecting wedge 10, a self-switching thrust wedge 16 is located in a different groove of the eccentric ring 5 with approximately radial movement and interaction with the notches 17 of the drive shaft 1 and the recesses 18 of the connecting rod 7. There are guides on the thrust wedge 16 and on the corresponding notches 17 and 18 surfaces 19, 20 and 21, 22 for displacing the stop wedge 16 from the recesses. Cam tools 13 and 14 were also used to fix the stop wedge in the grooves. The recesses 11 and 17 associated with the drive shaft 1, as well as the cam means 14, are filled with rings in the flange 23. This flange is simultaneously used to limit the axial displacement of the roller bearing 6. The connecting wedge 10 is located in the groove 24 of the eccentric ring 5 with the possibility of moving parallel to the beam 25 of the drive shaft 1. The connecting wedge 10 has a lateral surface 27 parallel to the direction of movement 26 for interacting with the surface 28 of the recess 11. In addition, the connecting wedge 10 has a lateral surface 29 interacting with the supporting surface of the DA in the eccentric ring 5. In this case, the connecting wedge 10 is so far removed from the radial 143454 beam 25, that the surface 28 of the recess 11 is approximately opposite to the surface 30 in the eccentric ring 5 and approximately equal to 5 in area, which is necessary to eliminate the flexural loads on the connecting wedge 10. The connecting wedge 10 is spring-loaded with a spring 31 in the direction of the drive shaft 1. The recess 11 of the drive shaft 1 has an approximately tangential surface 32 to ensure a soft entry of the connecting wedge 10 under the action of the spring 31 into the recesses 11. The connecting wedge 10 (Fig. 5) is provided with a pinch SpZ, providing spring properties to the wedge, and a protrusion 3-4 to interact with the protrusion 35 of the switching body 15. The switching body 15 is made in the form of a ring, which with its end blocks the trajectory of the protrusion 34 and has the directions of the groove 36 for accommodating a vute in it. The inner cylindrical surface 37 of the guide groove 36 comprises a guide protrusion 35. The switching member 15 is pivotally mounted on an axis 38 parallel to the drive shaft 1. The programmer 39 serves to move. switch body 15 according to a predetermined program. The notches 12 of the connecting rod 7 also have an approximately tangential surface 40 and an inclined surface 4 of the cam means 13 and the notch is made in the ring 42 located laterally on the connecting rod 7. The ring 42, fastened to the connecting rod 7 with screws 43 and pins 44, simultaneously serves to secure in the axial direction of the connecting rod 7 and the roller bearing 6 on the eccentric lance 5. Screws 43 and pins 44 are made safe. The stop wedge 16 is located in the groove 45 of the eccentric ring 5 with the ability to move in the radial direction 46. The front side surface 47 of the stop wedge 16 facing the drive shaft 1, as well as the rear side surface 48 facing the connecting rod 7, form an acute angle 46 along the direction 46 while approximately parallel to the center beam 25, the surface 49 of the recess $ 1 17 is also approximately parallel to the beam 25. The width B of the recess 17 of the drive shaft 1 is smaller than the width B of the connecting wedge 10 to prevent it from falling into the recess 17 for the thrust wedge 16 .. On the eccentric ring 5 a latch 50 is placed, spring loaded 51 in the direction of the thrust wedge 16, with the ability to interact with the thrust wedge 16 by means of the nose 52 and the notch 53 of the thrust wedge 16. The latch 50 is mounted together with the thrust wedge 16 and the connecting wedge 10 by means of a stop plate .54 with a screw 55 on the end of the eccentric ring 5. A recess 18 which is connected to the connecting rod 7 is made on the ring 56 mounted on the side of the connecting rod 7 opposite to the ring 42 (in the ring 42 there are recesses 12 for connecting wedge). The ring 56 also contains cam means 13 for fixing the stop wedge 16. The ring 56 is used to secure the axial direction of the connecting rod 7 and the roller support 6 on the eccentric ring 5. It is also possible that the rings 42 and 56 are reinforced concentrically to the drive shaft, 1 on a fixed case (not shown). The operation of the heald carriage is shown in FIG. 6-13. FIG. 6, the switching clutch is in phase. In which the drive shaft 1 rotates freely within the eccentric ring 5, the connecting wedge 10 is inserted into the outlets 12, and the wedge 16 is inserted into the recesses 18 that are connected to the shaft 7. The eccentric ring 5 is fixed relative to the rod 7 and is held still. FIG. 7 and 8 show the phases corresponding to the inclusion, i.e. the connection of the eccentric ring 5 with the drive shaft. This occurs when the switching organ 15 is in position S, in which the protrusion 35 of the switching organ 15 releases the protrusion 34 of the connecting wedge 10, whereby the connecting wedge 10, under the influence of the spring 32, slides along the tangential surface 37 and 56 into the recess 11, pressing against the surface 28. The ejector wedge 16, which is still held by the latch 50 in the recess 18 of the connecting rod 7, is now opposite the recess 17 of the drive shaft 1. During the following moments, the drive shaft 1 continues to turn in the direction and arrows A, carrying the eccentric ring 5 behind, while the stop wedge 16, guided by the surface 22 of the recess 18, is displaced from this recess and enters the recess 17 of the drive shaft 1. In this case, the latch 50 with its nose 52 enters the recess 53 and presses the stop wedge 16 to the recess 17. The front side surface 47 of the stop wedge 16, interacting with the side surface 49 of the recess 17, prevents the formation of a gap between the drive shaft 1 and the eccentric ring 5. During further rotation of the drive shaft from the position shown in FIG. 8 to the position shown in FIG. 9, the lever 9 moves from the H- position to the H position, wherein the end surface of the connecting wedge 10 slides over the cam means 13 of the ring 42, and the end surface of the thrust wedge 16. slides along the cam means 13 of the ring 56, thanks to the casing, locking the wedges is provided 10 and 16 in the on position. If the switching organ 15 (Fig. 1) remains in the Sj position, the switching off (Figs. 9-12) occurs. In this direction, the protrusion 35 of the switching element 15, acting on the protrusion 34 of the connecting wedge 10, pulls it out of the 11 of the drive shaft 1. As the drive shaft 1 brakes during switching, the eccentric ring 1.0 under the action of inertial forces tends to overtake the drive shaft 1. These inertia forces perceive an elastic wedge 16, which with its front side surface 47 is received, against the side surface 49 of the recess 17j, thereby creating the possibility of a free exit of the connecting wedge 10 from the recess 11 of the rivo bottom shaft 1. Connecting line 10, exit from the recess 11 actuator .71 The shaft 1 enters the recess 12 of the connecting rod 7 and connects the eccentric ring 5 to the connecting rod 7, so that further rotation of the eccentric ring 5 becomes impossible (Figure 10). Subsequently, the drive shaft 1 continues to rotate rapidly without the eccentric ring 5, while the thrust wedge 16 is pushed out of the recess 17 of the drive shaft 1 by means of the guide surface 21 and passes into the recess 18 of the connecting rod 7. The latch 50 displaced from the notch 53 of the thrust wedge 16 It remains pressed against its side surface, thereby keeping the stop wedge 16 against any movement to the drive shaft at the moments of passage over its recesses. The drive shaft 1 can now rotate freely, with the cam means 14 of the drive shaft 1 U345 block the output of the connecting and thrust wedges from the grooves of the connecting rod. The next switching can now start only after 5, as the drive shaft 1 has been rotated 180 °. . . The following two switching combinations are possible: if the organ of switching 15 takes the position S, the crank 7 goes (or remains) in the position H, if the switching organ 15 takes the position 5, then the connecting rod 7 goes (or remains) in the position Hj. FIG. 13 shows the position in which the thrust wedge 16 spontaneously, for example when the spring 51 breaks, moves to the position X to the driven shaft 1. In this case, the surface 28 acts on the surface 19 of the thrust wedge 16, which, without causing breakdowns, returns to its normal position. ff 79 l4 (.t 8 36 7 56 654 6 / fi / 6 "7 FIG L 1114345 -XJ // FIG. g 15 56 57 Fig.Z /ABOUT 33 FIG. 5 fO J / / J / 56 LL 54 55 / Z FIG. 6 FIG. eight FIG. fO sriv. eleven
