Avomo pursuit gear 16 is secured for mounting the device it is fixed relative overhead of the idle gear 17 (in the special case that can only be a flange portion of a gear sector). On the left gear train 14, four equally spaced axles 18 are fastened, on which gears 19c are mounted with the possibility of rotation relative to these axes. In the same pursuit, in the roller guides 20, there are four-way folding folding heads with toothed racks 21, which engage with gears 19. The gears 19 are simultaneously engaged with the intermediate gear wheel 17. The left-hand gear shoulder 14 is engaged with gear 22, which is mounted on a carrier of the differential 23. The right spike 16 is in engagement with the gear 24, which is fixed on one hollow shaft with a bevel gear of the same differential 23. The carrier of the differential 23 through the gear a pair 25 is connected to the drive shaft 26. The drive gear housing 27 is fastened to the carriage body. In addition, through the gear pair 28, the drive shaft 26 is connected with the feedback sensor 29 in position, and the gear pair 30 with the feedback sensor 31 in the drive speed 14. The rotation of the drive gear of the differential 23 is also transmitted through gears 32 and 33 from drive shaft 34. The drive 34 controls the movement of the spreader through the rails 21. The drive shaft 34 through the gear pair 36 is connected to the sensor 36 in position, and through the gear pair 37, the sensor 38 in the speed of the spreader. The kinematic chain from the drive 5 of the carriage 3 to the bed 1, which also has sensors in position and speed of the carriage, is not shown in the drawings, since it is a conventional gearbox. The tagger is made in the form of four. The split clamps 39, which are located symmetrically on the left chase 14 and are mounted in housings 40 on roller guides 20 and 41. On the left chase 14 are four coils 42 for the main winding material and four coils 43 for receiving from the coils 42 a separating substrate (improving manufacturability of the wound material). Disc brakes 44 are located coplanar with coils 42 and 43, rollers 45-47 of tape tracts. The axis of one of these rollers, for example 47, is spring loaded to sample the belt slack when the direction of movement of the carriage is changed at small about 30 winding angles (not shown). In the drawing of FIG. 4, on a scale enlarged with respect to the image of FIG. 3, the construction of the folding head 39 (type B-B from FIG. 3) is shown with a self-aligning folding roller 48, the axis of which is attached to the hub 49 mounted on a ball The support 50 in the flange 51 of the skip 52, installed in the roller directions Sugs 20 and 41. With a rolling pin 52, the inactive lever is connected to the rack bar 21, shown in Fig. 2. (The fastening of the roller directions 20 to the chase 14 is not shown in the drawing). In the drawing of FIG. 5, the module 53 of the bed 1 is shown, which is a box-shaped (for example, welded) structure. On the upper plane of the module of the frame, a gear rail 54 is attached, with which the coupling 5 to the output gear of the drive 5 is carriage 3 (not shown) and two guides 55 for the carriage 3. On the bottom plane there are two guides 56, 1x installed supporting heads 11 with the possibility of their adjustment movement along these guides, as well as modules of supports 2 are installed with the possibility of the same adjustment movement. The lengths of the frame of the module 53 of the bed, guides 55 and 56, the slats 54 are equal to each other, therefore the docking of the modules of the bed does not require fitting. After the exhibition in the transverse direction, the modules are fastened with bolts 57 and are pinned at the joints to form a single frame. In the drawing of Fig. B, the structure of the support module 2 is shown made in the form of a pneumatic manipulator. The support module consists of a housing 58 mounted on the lower guides of the 56 modules of the bed. In the housing 58, a pneumatic cylinder 59 is mounted of a two-sided action with a rod 60 (which, in turn, can be telescopic), a yutan control of the pneumatic cylinder 61 and a locking mechanism 62. A rod 63 and a sliding screw 64 are fastened on the rod 60 , 6 The locking mechanism 62 has an emphasis 66, a retaining spring 67 with a pusher 68. In addition, FIG. 6 shows the limit switch 69, the stop 70 mounted on the carriage 3. The stop 70 is located in the longitudinal direction and has symmetrical departures on both sides of the carriage, In the drawing of FIG. 7, on a larger scale with respect to the image of FIG. 6, a portion of the rod 60 with the lodgment 65 is shown. Two stem 71 and 72 are between the lodgement 60 and the retractable screw 64. Between the lodgement 65 and the retractable screw 64 there are four adjustment screws 73 for orienting the bed in the hinge joint. On each cradle, they are mounted with screws 74 on two side folding lever stoppers 75, spring-loaded with sticks 76 and having rollers 77 and 78. There are grooves 79 in cradles. Mandrel 8 for winding the product is fixed in cartridges 9 of two support heads 11, stretched using pinolegs 10 and supported by supports 2. When the mill settings for winding products whose length difference is greater than the pinwheel code 10, the headstock 11 moves along the guides 56 of the modules 53 of the frame 1 and are fixed to the required distance between them (see Fig. 1 and 5). With specialization of production at some specific lengths, we wind 1, 1x products, the machine dimensions can be changed by multiples of the lengths of modules 53, only an exhibition in the transverse direction of modules 53 is required, the hooks 55 and 56 are identical, and the teeth of the rails 54 are terminated in a single module 53 in the same phase. The described machine works as follows. In the left chase 14 (see FIG. 3), coils 42 with winding material are installed across the board, the free ends of which are passed through the rooks 45, brakes 44, rollers 46 and 7, folding heads 39, roles 48 and are attached to the mandrel 8. Simultaneously with coils 42 put coils 43 for coiling the intermediate substrate. From the actuator 5 (see Fig. 1), the carriage 3 with the winding device 4 along the axis of the fixed mandrel 8 receives (arrow D in the drawings of Fig. 1 and Fig. 2). From the actuator 26 (see FIG. 2), rotation through the kinematic chain 25, 23, 24, 22 is connected to gear prints 14 and 16. The number of gear teeth of the pair 25 and 22, shoulder strap 14 and differential gear teeth 23 and 24, shoulder strap 16 are selected in this way so that when the drive 34 of the folding heads 39 is fixed, in order to perform circumferential winding, both shoulder straps rotate synchronously around the axis of the mandrel 8 (arrow E in FIG. 3). In order to obtain a winding angle, especially less than 30 °, the actuator 34 is turned on (see Fig. 2). Moreover, in addition to the rotational movement relative to the mandrel 8, the gear train 16 with the intermediate wheel 17 receives a rotational motion relative to the shoulder strap 14 of the gear cog 32 and 33, the differential 23, gear 24, and consequently, rotation and four gears 19 are obtained; from here, the movement and toothed racks 21 of the folding head 39 are placed, and the folding head 39 can move to the center of the mandrel or in the opposite direction (arrows G in FIG. 3) depending on the direction of rotation of the drive 34. Depending on the position of the tape on the mandrel 8, the folding rollers 48 together with the sleeves 49 are unfolded (the arrows ifa 4 in the belt itself in the rolling supports 50 mounted in the flanges 51 of the folding heads 39. The speed of movement of the carriage 3, the shoulder strap 14, and the speed and movement trajectory of the races masonry heads, 39 are selected when calculating the program for winding a particular product.If in some special production situations you only need to work with one racking-out folding head (the need to enter some local asymmetrical recesses, then the remaining heads can be easily dismantled) During the work on the program, the carriage 3, not the income for the calculated distance to the supporting support, with its cantilever support 70 (see Fig. 6) presses the control valve 61, which gives the command to lower the rod 60 s ozhementom. 65. The rod with the lodgement goes down, the stop screw 63 pushes the pusher 68, which pulls down the spring-loaded stop 66 of the locking mechanism 62 and the carriage 3 passes the support zone (see Fig. 1). As soon as the stop 70 of the carriage 3 moves out of the control valve 61, the rod with the lodgement will rise up and take up the working position. If, after actuation of the control valve 61 on lowering the support, the rod 60 with the lodgement 65 for some reason does not fall, then, during its movement, the carriage 3 will move with a trigger switch 69 on the spring-loaded stop 66 of the locking mechanism 62 and stop as the stop 66 will not be omitted. Traveling switches 69 are located console on both sides along the carriage. The lengths of the consoles on which the switches 69 are located, in the course of the carriage movement are less than the lengths of the consoles of the stops 70, this difference is chosen so that, even at the maximum speed of the carriage movement, the time between the moment the valve 61 is turned on and the time the switch situation) would be no less than the time of operation of the support when lowering. The principle of control is not dependent on which side the carriage comes from. The support module can be mounted on the guides 56 in any place of the bed module. The number of modules of the supports is determined by the stiffness of the mandrel. In accordance with the shape of the winding mandrel 8, an exhibition of lodgements 65 of all the used supports 2 is made. In the vertical direction (in height), the lodgement 65 is exposed by the sliding screw 64 (see FIG. 7 and FIG. 6) and the nuts 71 and 72. The platform of the lodgement 65 is inclined relative to the horizontal plane by orienting the hinge connection between the platform of the lodgement 65 and the remote screw 64, using four screws 73. The distance between the spring-loaded arms 75 is changed by the groove 79 and the screws 74. If necessary, the 73 can be easily replaced with levers or special hooks of another shape. The proposed machine compares favorably with the prototype and other analogs. gov, currently known. The construction of the frame, made in the form of separate dockable modules, allows the machine to be installed under the products of the size and row of a specific production, as a result of which the production areas are saved and, at the same time, the possibilities of the machine for obtaining large sizes in other productions are not limited. 9 ° The presence of support modules on the frame, made in the form of pneumatic manipulators with support for hivayuE (they use lodgments, allows to wrap with winding angles from 0 to 90 fixed mandrels of very small pestleiness that could not be rolled up on the previously existing equipment. heads and lodgements of supports that occupy the mandrel through the required length interval, minimizes all types of possible deformations of unstable long mandrels, which allows to obtain a stable and high-quality tool of the material being wound, which ultimately increases the quality of the whole obtained piece. The work of the dispenser at the same time by four razlatochnykh golod-sh in four times increases the productivity of the machine compared to the prototype. various spatial configurations.
