    • 专利摘要:
    The eccentric (6) carries a locking lever (94) which is under the effect of a spring (95) and which is pivotable about (93). By means of its arm (97), the pawl (5) held in the coupling position according to Fig. 2 under the effect of the spring (60) can be locked positively as a result of the engagement of the extension (98) over it. The two pivoting arms (B) and (C) of the pawl (5) and locking lever (94) respectively are vertically on one another at the contact point (A), thereby achieving the self-fixing of the lock. It is thereby possible to avoid the possibility that the pawl (5) will inadvertently assume the uncoupled position (5a, 61a) shown in Fig. 1, for example as a result of vibrations and centrifugal forces in the machine or if the spring (60) breaks or when there are unintentional manipulations by an attendant. <IMAGE>

    The invention relates to the design of a rotary helix carriage: a weaving machine in which the converter is two-sided (the eccentric is connected and disconnected according to a predetermined program with the shaft, periodically activates. vrgdden and having at least one groove to accommodate the pawl mounted on the eccentric, mounted on the drive shaft can be rotated and nematic connected with the weaving machine through a connecting rod encompassing the cam and a lever system and at least one two-arm control lever, the control arm of which is installed with the ability to interact with the pawl, and the free arm is connected with the device of the lifting knife by means of platinum installed the possibility of reciprocating and pivotally connected with the free arm of the control lever tlj. A disadvantage of the known device is that due to vibration or high prices robezhnEOS loads, and also when there is a failure probability prukiny nesvoevremennog release pawl of the cam groove of the drive shaft and, together with the probability of an emergency. The purpose of the invention is to increase the reliability of the carriage operation for eliminating the possible untimely exit of the eccentric pawl from the groove of the drive shaft. The goal is achieved by the fact that a weaving machine carriage containing a drive shaft, installed with the possibility of periodic rotation and having at least one groove for accommodating a pawl mounted on an eccentric mounted on the drive shaft can be rotated and is kinematically connected with a swing a weaving machine by means of a connecting rod encompassing an eccentric and a system of levers, and at least one two-arm control lever whose control arm is installed with the possibility of with the pawl, and the free shoulder is connected with the device of the lifting knife by means of a plate that is installed with the possibility of reciprocating motion and hingedly connected with the free shoulder of the control lever, contains a locking device for locking the pawl in the position of adhesion with a water shaft, including spring-loaded lever, hinged on the eccentric and having a power shoulder and at least one slide rigidly mounted on the connecting rod, for engagement with the power shoulder of the lock lever, with the stop The orient lever has a trough, and the pawl has a protrusion for engaging with the trough of the lever in the engaged position, the contacting surfaces of the protrusion and the troughs are located in mutually perpendicular planes passing through the axes of rotation of the lock lever and the pawl. Fig. I shows the carriage at the time of engagement of the locking pawl with the slide of the connecting rod; in fig. 2 "carriage at the moment when the dog is locked. The drive shaft 1 has two grooves 2, in one of them there is a protrusion J3 with a spring-loaded spring 4 of the pawl 5 rotatably mounted on the axis 6, which is fixed on the eccentric Z .. installed rotatably on the shaft 1. The eccentric 7 is covered by a rod 8 of the connecting rod 9, which at point 10 is pivotally connected to rechgarm 11, which is kinematically associated with a helix. The eccentric 7, the connecting rod 9, the lever 11 together make up the shaft drive. The number of such drives mounted on shaft 1 corresponds to the number of weaving loom shanks. To interact with dog 5, axes 12 and 13 are rotatably mounted control levers 14-17, the control arms 14 and 16 of which have hooks 18 for engaging dog 60 protrusion 19. Free shoulders 15 and 17 of these arms are connected between at the point 20. Ple-1 cho 17 is spring-loaded by the spring 21, and the arm 15 is pivotally connected at the point 22 with the platinum 23 installed, with the possibility of interacting with the knife 24, according to a predetermined program. To limit the motion of the control levers 1417 and platinum 23 under the action of the spring 21, a stop 25 is installed opposite the arm 17. On the eccentric 5, a locking pawl 27, spring-loaded 28, is mounted on the axis 26. The locking shoulder 29 of the pawl 27 has a depression 30 for interacting with dog protrusion 31 5. In addition, the stopper dog 27 has an incoming shoulder 32 for engaging with slides 33 and 34 rigidly mounted on a connecting rod 8. In this case, the contact surfaces of the protrusion 31 and the depression 30 are in the locked position (FIG. 2) p are located in mutually perpendicular planes B and C, passing respectively through the axis 6 of the dog 5 and through the axis 26 of the lock dog 27.
