    {The invention relates to weaving machines and can be used on program-controlled machines,
    Pel invention - the reliability of operation and ease of maintenance.
    Fig, I schematically depicts the proposed device for finding the times of a weaving machine with one planetary gear; - Fig, 2 - a planetary gear, cross section; Figures 3-10 show parts of the planetary gear in different phases of movement; FIG. 11 shows the device in the presence of two planetary gears and a co-programming device.
    According to FIG. 1, the main shaft 1 of the weaving machine drives through the sprocket 2 and the chain 3 - the sprocket 4, which is attached to the input shaft 5 of the first stage of the planetary gear 6, the output shaft 7 of the third stage of the planetary gear 6 has two sprockets 8 and 9 to bring , the action of the working bodies 10 and 11 of the weaving machine, which may be, for example, the main or commodity controller, or devices for forming the weaving loom.
    The third working member may be a color changing device, also actuated by an asterisk or a device for forming a pharynx. Planetary gear 6 contributes to the fact that the driven sprockets 4 and the driven sprockets 8, 9 during operation rotate in the same direction at the same speed, that is, the planar gear can be used in a loom. This is achieved as follows.
    During weaving, the sprocket 4 drives the drive shaft 5 of the first stage of the planetary gear unit b with a certain direction and a certain speed of rotation. The shaft 5, via jumper 12 (FIG. 2), actuates with a finger I3 a planetary wheel 14 of the first stage of the planetary gear set rotatably on it, rotating in a stationary floor driving wheel 15. with internal gearing and driving the driven solar wheel 123292
    from 16, the Slave wheel 16 rotates the planetary wheel 17 of the second stage of the planetary gear, having the same number of teeth as the co-. 5 leso 14 of the first stage of the planetary gear.
    In addition, the device has a worm pair 18 with a shaft-19 and a wheel 20, the worm gear 20 is mounted 0 and is broken at the output shaft 7 of the third stage of the planetary gear and is rigidly connected to the driven wheel 21 with the internal gearing of the second stage of the planetary gear having the same
    15 the number of teeth as the drive wheel 15 of the first stage. The worm gear 20 can interact with the rotary fixation pin 22. - position of the output shaft
    20 7 planetary gear.
    The locking pin 22 can enter into one of two diametrically located grooves 23 of the worm gear 20, which is rigidly connected to the second-stage driven wheel 21 of the planetary gear, which is engaged with the second-stage planetary wheel 17, which through the finger 24 and the jumper 25 leads in rotation
    30 output shaft 7 with asterisks 8 and 9,. Since the wheel sets 14-: 15-16 and 16-17-18 are identical and driven in the opposite direction, the sprockets 4.8 and 9 rotate in the same direction and at the same speed.
    The planetary gear 6 is connected to the rotary control means 26 by the position of the output shaft of the planetary gear. The means 26 also has means for moving the locking pin 22 in the radial direction, including a control disk 28 mounted on the motor shaft 27 with a slotted control cam 29, The control cam 29 has a roller 30 located on the locking pin 22, the Worm wheel 20 has a notch as well 23 is a diametrically opposed groove 31 (FIGS. 3 and 4), which may include a pin 22 depending on the position of the worm gear. The position of the locking pin 22 inside and outside of the slots 23 and 31 is recorded by the sensitive elements 32 and 33, together with a suitable switching device 34.
    3
    the device also has a switch 35 connected to the programming device 36, which via line 37 is connected to the motor 27 for crossing the locking finger 22 spring loaded 38, moving the finger 22 through the switching device FOR, sensing element 33, line 39 of the controlling device 3b and line 40 controls the servomotor 41, the motor 41 is connected to a variable transmission 42, on the shaft 43 of which a shaft 19 of a worm is fastened. Transmission 18, to prevent the locking pin from being prematurely hit 22, a third stage of the planetary wheels 44 is provided in the second groove 31 in the case of the planetary gear 6. The set of planetary wheels 44 includes a second internal gear 45, rigidly connected to the worm wheel 20, and a planetary wheel 46 having the same number of teeth, as the planetary wheel 17. The planetary wheel 46 rotates on a fixed solar wheel 47 having the same number of teeth as the driven sun wheel 16. The planetary wheel 47 actuates the steering wheel 49 via the pin 48 and 26, Thus, the disk 49 rotates when searching for times synchronously with asterisks 8 and 9, i.e., one revolution of this disk corresponds to one revolution of asterisks 8 and 9. Disk 49 has an open radial groove 50 for locking it with the locking pin 22. i. ..
    When searching for times, the device works as follows.
    In the event that a weaver thread monitor of a weaving machine detects a defective weaving thread and the drive is turned off by a thread monitor, then the weaving machine stops with all the aggregates. Thus, the sprocket 4, the shaft 5, the jumper 12, the planetary wheel 14 and the driven sun wheel 16 of the first stage of the planetary gear set to stop. The weft thread is first removed from the pharynx. Then, using the switch: 35, the programmer includes a tool, device 36, as a result of which the discovery begins. The programming device 36 includes through l and 123294
    37, the engine 27, so that the locking pin 22 of the control means 26 by the position of the output shaft 7 of the transmission 6 is removed by the disk 28 from the groove 5 23 of the worm gear 20, wherein
    the switching device 34 causes a signal in the sensing element 33 via the line 39 of the programming device 36, which then turns on 10 through the servo motor line 40. Tel 41; In this case, the servomotor 41 drives, via a belt drive 42, a shaft 43, on which is attached a shaft 19 of a screw pair 18,
    15 A toothed driven wheel 21 with internal engagement of the second stage of the planetary gear drives the planetary wheel 17, strung along the stationary driven co-forest of the first stage of the planetary gear, and through the pin 24 and jumper 25 the output shaft 7 is actuated and thus the sprocket 8 and 9, Gris is the asterisks 8
    25 and 9 rotate in the opposite direction, as during weaving. Thus, the sprockets 8 and 9 bring back both working bodies 10 and 11 to the correct position relative to the weaving machine, namely, due to the reduced worm gear and planetary wheels 16-17-21 of the rotation speed of the servo 41.
    At this time, the control disk 28 made one turn and the actuator 27 is turned on by the programming device 36. At the end of the revolution the control disk releases the locking
    .Q finger 22, which, however, cannot engage with the groove 23 of the worm gear 20,
    In order for the control dial 28 to be returned one duck (in order to avoid a phase shift between the working position and the loom), the rotation in the opposite direction of the sprockets 8 and 9 must also be exactly one full turn. The speed of the worm wheel 20 depends on the planetary wheels 16-17-21. It is assumed that the worm gear 20 performs one and a half turns, and other transmission speeds are also possible. In addition, the worm gear 20 has a second groove 31 which is diametrically located relative to the groove 23,
    35
    $
    The interaction of the worm gear 20 and disk 49 during the search for times is depicted in FIGS. 1-10.
    On fng.Z and 4 shows the position
    at the beginning of the search time, when the locking finger 22 is removed by the disk 2 from the grooves 23 and 50, as a result of which the worm gear 20 and the disk 49 begin to rotate. In FIG. Figures 5 and 6 show the worm gear 20 after 180 ° rotation. In this position, the locking pin 22 could fit into the groove 31, however, this is prevented by the disk 49, since this disk 49 with the groove 50 is turned only 120 °. Figs 7 and 8 show a worm wheel after turning 360. The disk 49 still prevents the fixing finger 22 from entering the groove. Figs 9 and 10 show a worm gear 20 after one and a half turns. Now the locking pin 22 can enter the grooves 31 and 50 under the pressure of the spring 38, the disk 49 and the sprockets 8 and 9 make one turn. This corresponds to the possible movement of the working bodies 10 and 11 on one side of the tank,
    Dp returning the working bodies 1 and I1 for one duck should be rotated back one turn. However, the working bodies can perform different movements with one search, for example, one unit should be turned back one turn and the other two turns forward. In this case, two planetary gears should be used. FIG. And depicts an exemplary embodiment of such a device.
    A chain drive consisting of asterisks 2.4 and 51 and roller chain 3 drives two planetary gears 6 and 52, the driven shafts 7 or 53 of these planetary gears provide






    wives with sprockets 8 or 54. Sprocket servo drive program 45 asterisk 8 is part of chain drive 55 for actuating the tool 10. Star 54 is part of chain gear 56 for driving the tool 11 of the weaving JQ weaving machine. The planetary gear 6 is provided with a pivoting means 26 for controlling the position of the outboard shaft 7 with the engine 27, and the planetary gear 52 with a pivoting means 58
    are.
    As a result of using the proposed device, the output shaft of the planetary gear is rotated with a rotation speed equal to the rotation speed of the input shaft, which eliminates the phase shift of the working parts of the weaving machine and increases the reliability of the device.
    controlling the position of the output shaft 53 with the engine 58; In addition, a servo drive 41 and a planetary gear are connected to the planetary gear 6; 5 52 and a servo drive 59, the design of the planetary gear, turning gears and servo drives are shown in FIGS. 1 and 2. In addition, a co-programming tool is provided 36 to control the turning tools 26 to 57 to servo-i drives 41 and 59 driven by means of switch 35, control device 36
    5 has for each working body, 10 and 11 a program 60 or 61 drive with data for movement that fulfills the working body during the search, i.e., each of them performs the required number of revolutions independently of each other when searching for . NII times until they have reached the position necessary to continue the work of the loom.
    5 At the beginning of the search times, if the asterisks are 4 and 51; stopped due to the weaving of the weaving machine, the programming device 36 is turned on by means of a switch, and
    0, programs for the movement of the working bodies 10 and 11 of the machine are carried out. First, for both turning means 26 and 57, the engines 27 or 58 are turned on and thus ceased
    J Blocking turning tool. Then, servos 4 and 58 turn on, driving the worm gear in each planetary gear 6.52 so that the sprockets 8 or 54 receive the direction of rotation and the number of revolutions required for
    go to the working bodies in the correct working position relative to the weaving machine. After the program has ended, the servos will turn off
    are.
    As a result of using the proposed device, the output shaft of the planetary gear is rotated with a rotation speed equal to the rotation speed of the input shaft, which eliminates the phase shift of the working parts of the weaving machine and increases the reliability of the device.
