SU115224A1 - Machine for rewinding yarn and thread in skeins - Google Patents

Description

The known devices for rewinding yarns and threads into a skein carry out only rewinding, and threading the threads before rewinding, knitting the skein, knotting its ends and other operations are performed manually.

The proposed machine greatly improves labor productivity by automating the operations of capturing the ends of the threads unrolled from the bobbins at the beginning of rewinding, winding a coil of a given length, intersecting the ends and tying them with a knot, cutting off the ends of the knot, removing the coils and accounting.

The machine is made in the form of a rotating table mounted freely on a vertical stationary shaft mounted on a frame, rotating around the last six vertical rotating crowns for winding coils and rigidly connected to the table frame. On the frame above each crown are mounted the mechanism of the thread guide with the hook of the pick-up of the thread unrolled from the reel, the mechanism of intersection and connection of the ends of the skein and the mechanism of resetting the coils from the crowns to the receiver of the coils, kinematically connected with the counting mechanism of counting the coils.

On the axles of rotation of the crowns, gears are fitted that interact with a fixed, located under the table, horizontal ring having a gear cut along an arc of 300 °. The axles of the crowns are mounted in bearings attached to the bottom plane of the table.

On the upper surface of the table, groove and ring-shaped cams are coaxially fastened, which drive the stationary horizontal knot mechanism. One end of the base assemblies is hinged to a sleeve freely seated on the vertical shaft, and the other end of the base is provided with a roller supported on a shaped support of a sector-like horizontal panel attached to the vertical shaft.

The mechanism of the thread hook crochet yarn includes two rollers interacting with reinforcements on a sector-like panel with a profiled bar, mounted on the ends of the double-shoulders No. 115224-2 -

new levers, one of which is kinematically connected with a hook for picking up the thread, and the other with a spring-loaded thread guide and with a hook for picking up the thread through a roller that interacts with the profile bar fixed on the lever that is connected to the hook of the pickup.

The mechanism of intersection and connection of the ends of the coil with its base on one side is pivotally connected with a sleeve which is loosely mounted on the vertical shaft and rigidly connected to the frame, and on the other side freely rests on the support ring attached by racks to the sector-like panel.

The mechanism of intersection and connection of the ends of the coil includes a hook fitted with the pressure plate, which transmits the thread to the pick-up hook attached to the lever carrying the roller, which enters the horizontal movement of the hook into the shaped groove of the support ring, which has a shaped recess for moving the hook vertically.

The mechanism of dumping hanks from crowns to the receiver consists of a lever with an axis; mounted on a frame that has a roller that interacts with a groove and a protrusion of the support ring, and a brace with a spring-loaded pawl, a disc-shaped clip for the thread, which has a pin, and interacts with the last two-arm lever; in the upper part of the bracket, a single-arm lever is attached to the hinge, fitted at the end with a swivel foot, dropping a coil and connected to a spring-loaded hinge plate that interacts with a spring-loaded dog.

The receiver of coils has four horns fixed on the head of the receiver, periodically rotated by 90 ° after dropping on each of the twenty-five coils by a counting mechanism, the drive lever of which interacts in series with each of the six arms of the table attached to the lower surface of the table.

A spring clip is mounted on one of the needles of each crown, driven by a hinged lever fixed at the end of the spokes, carrying a roller at the end, which interacts in series with the stop and wedge mounted on the sector-like panel.

FIG. 1 shows an automatic machine, a vertical axial section; in fig. 2 - automatic table, plan view; in fig. 3 - the kinematic scheme of the thread guide mechanism with the hook of the pickup thread (a) and the kinematic scheme of the machine knot mechanism (b), the scheme of the mechanism of intersection and connection of the ends of the skein (c) and the scheme of the mechanism of resetting the skeins from the crowns (d); in fig. 4 - horizontal sector-shaped nanevib, plan view; in fig. 5 - crown with spring clip (a) and mounting scheme for the crown axis in bearings (b); in fig. 6 is a plan view of a support ring; Fig. 7 is a diagram of a receiver of coils with a counting mechanism (a) and a plan view of a horizontal ring with a gear cut along an arc of 300 ° (b).

On the base 1, an electric motor 2 is mounted, from which, via a V-belt transmission, a worm gear, a bevel and a cylindrical gear pair, the movement is transmitted to the table 3, continuously rotating clockwise around the vertical shaft 4.

The vertical shaft 4 is rigidly connected to the frame and is a fixed axis on which the main mechanisms of the machine are mounted.

On the upper plane of the table 3, the groove cam 5 and the annular cam 6 are rigidly fixed. The locks 5 and 5 drive the knot mechanism. To the lower plane of the table, bearings 6 are fixed at equal intervals around the circumference of six crowns 8 and six stops 9, which play the role of cams for feeding pulses to the counting mechanism.

On one of the six spokes of each crown, a spring clip 10 is fastened, which serves to grip the end of the thread at the beginning of winding. On each axis

the gear crown 71 has a gear // planted, a drum brake drum 12 and a spring 13, with which M is connected to the locking cam 15 freely on the crown axis.

Under the table 3 to the frame on the brackets 16, a horizontal ring / 7 is fixedly fixed with a gear cut 18 along an arc of 300 ° and a smooth segment 19. The radius of the gear segment is less than a smooth segment; Thus, when the table is above the smooth segment 19, only the cam 15 can pass through the friction system, and only the gear 11 kroons over the gear segment 18. When entering the area of the gear segment, the crown gear // engages with it and, rolling over its teeth, rotates the crown 8 around its axis, winding it. When leaving the toothed segment, the crown gear leaves the gearing: at this time, the locking cam 15 with its flat bottom rests on the smooth segment 19 and, slipping over the latter, keeps the crown 8 from rotating around its axis at the position of the clamp 10 at the top. In the area of the toothed segment all the time there are five crowns, and in the area of the smooth segment there is one crown.

The frame 20 is rigidly associated with the table 3 and rotates with it around the vertical shaft 4.

On frame 20 above each crown, six mechanisms A of a yarn guide with a hook for picking up, a slot of mechanisms B of a skein discharge and six mechanisms B of a crosshair and a connection of the ends of the skein are strengthened.

The mechanism of intersection and connection of the ends of the coil with its base on the one hand is pivotally connected with the sleeve 21, rigidly connected with the frame 20, and on the other hand freely lies on the support ring 22 and slides along its surface during rotation of the frame.

The support ring 22 is fixed by means of racks on a sector-like panel 23 mounted on the shaft 4.

Above panel 23, in the zone of a smooth segment 19, a knob mechanism G of knots is installed, the base of which is hingedly connected to a sleeve 24, which sits freely on shaft 4 and has a limited angle of rotation. The roller 25 of the knotting mechanism G is supported on the profiled support 26.

The gear 27, which is rigidly mounted on the axis of the hook of the nodes of the hitch, is coupled to the rack 28, which is hingedly connected to the pillar 29 mounted on the panel 23.

On the hub 30, which is free to sit on the shaft 4, a mechanism for forceps, the sponges of which are located above the hook of the mechanism G for the knots, is fixed.

The thread from the reel 3} is guided through the thread guides 32 and guided to the thread guide 33 so that the end of the thread hangs below it to the clamping level 10 of the crown 8. When the crown leaves the zone of the smooth segment 19 of the ring 17 and approaches it to the toothed segment, the roller 34 of the clamp 10 attaches the protrusion 35 attached to the panel 23, and a wedge 36 opens the clamp 10. At this time, the crown roller 37 rolls onto the protrusion 38 of the panel, while the crown needle with the clamp deflects toward the hanging end of the thread and catches it with the clamp. When rollers 34 and 37 come off protrusions 35 and 38, a wedge 36 emerges from clip 10, the clip closes and clamps the end of the thread. The cam 15 comes off the smooth segment 19, and the crown gear 11 engages with the toothed segment of the ring. The crown begins to rotate around its axis, winding up. After winding, the crown leaves the engagement with the toothed segment and enters the zone of the smooth segment; The locking cam 15 of the crown finds its base on the smooth segment, and the roller 39 associated with the brake band 40 raids the protrusion 41 mounted on the frame, dampens the inertial force of the crown. The crown is reset to rewinding the skein.

The rollers 42 of the thread and thread mechanism, equipped with a hook 43 for picking up the thread, run over the profiled surface of the strip 44 fixed on the panel 23, the thread guide 33 tilts down and presses the last turn of the thread to the skein.

After this, the mechanism of intersection comes into effect. The roller 4 enters a fixed shaped groove 46 located on the inflow of the support ring 22 and causes the lever 47 with the hook 48 to move in the horizontal direction. At the same time, falling into the profiled trough 49 of the support ring, the intersection mechanism moves the hook 4b with the spring plate 50 fixed on it in the vertical direction.

Thus, the hook 48 captures the end of the first turn of the thread; at this time, clamping roller 34 runs onto a protrusion 5 / fastened on panel 23 and opens clamp 10 with a wedge 36. The end of the thread released from the clamp is intersected by a hook 48 of the intersection to the side and down under the skein, and then horizontally to the other side of the skein. in the zone of action of the hook 43 pickup paired with the thread guide 33.

The rollers 42, the passage along the profiled surface of the strip 44, cause the rollers 52 to roll along the profile bar 53 mounted on the lever 54 pivotally connected to the pick-up hook 43, thereby driving the latter. The hook 43 picks up the end of the thread from the hook 48 of the intersection and pushes it up to the thread guide 33 (towards the end of the last turn).

The roller 55 of the coil dumping mechanism enters the groove 56 of the support 22 and actuates the foot 57. The lever 55 rotates on the axis 59 towards the dog 60, the end of the spring-loaded bar 61 connected to the foot 57 slides along the dog 60 upward and reaches the end of the dog breaks down from it; as this, foot 57 rises up and, upon reaching the skein, lies on top of it. When the foot approaches the two shoulders hank, the lever 62 presses the pin 63 and the plates 64 clamps the thread to securely intersect the ends of the thread.

Upon further movement of the table 3 and the frame 20, both ends of the thread are transferred to the zone of action of the mechanism G of the knots.

The mechanism L of the pick-up thread guide pushes both ends of the thread up to the level of the jaws 65 of the tong mechanism G, and the intersection mechanism B returns to its original initial position.

The mechanism of the nodes of the nodes is activated. The cam 6 with the guide bar 66 acts on the crank 67, which is kinematically connected with the slider 68 knot knots. The nodes of the zatel along with the crawler. the slide along the guide 69 makes one cycle of the reciprocating movement, at which time both ends of the thread held by the thread guide 33 and the pick hook 43 overlap the nodes, which captures them with the barbell 70.

Then the cam 5, acting on the crank 7 /, rotates the entire mechanism of the assemblies at a certain angle clockwise relative to the shaft 4. The gear 27, rolling over the toothed rack 28, rotates the nodes of the detector around its axis. Knots zatel makes one full turn, screwing on the hook 72 the 70 ends of the thread captured by the antennae. In order to form a loop of the forming node of the assemblies, the feeder first lowers and then rises along the profile surface of the support 26, on which it is supported by the roller 25.

The ends of the coil, held by the hook 43 of the pick-up and the thread guide 33, enter into the jaw of the jaws 65 and at the same time into the slot of the lever 73, which is located above the nodes by the driver under the jaws. The slit of the lever 73 guides the ends of the coil to the opening of the hook 72.

The loop is removed from the antenna 70. The lever 74 locates one protube on the protrusion / of the rack 28, and the second end presses the protrusion 76 of the hook 72, which rotates iiiapHiijoe 77 n over the antenna 70. At this time, the roller 55 of the coil reset mechanism runs iia the protrusion 78 of the support ring 22 and the foot 57, pulling the coil from the knot knots, pulls the loop off the hook of the knots knotted and tightens the knot. The Alexaism of the nodes of the engine comes as far as the stop 79. rigidly connected with the lever 80 carrying the jaws 65 and the lever 73.

The roller 8 rolls onto the anvil 82 fixed on the panel 23, the lever 73 rotates on the axis 83 and presses on the sponge spring 84. The sponges close and clamp the carbon monoxide and filling ends of the coil (the carbon end — the end of the thread of the first turn of the coil, held by the pick hook 43, the refueling end — the end of the thread of the last turn of the coil, tucked into the thread guide 33).

Due to the rejection of the reeling mechanism of the coils, the carbon monoxide and the charging ends are cut off (the residual loop is cut) with the sharp edge 85 of the hook 72.

When the lever 73 rotates, its end with a slit, in which both ends of the thread are located, deviates from its initial position and separates the knot from the carbon and filling ends held by the jaws (the slit slits of the lever 73 are smaller than the dimensions of the knot and the knot does not pass into it) . When deflected, the lever pulls the knot away from the jaws; in this case, the ZTarn and the charging ends retained by them are pulled out of the assembly.

The roller 81 escapes from the stop 82, the jaws 65 open and release the ends of the thread.

Foot 57 pulls off a hank from the crown and drops it onto one of the four horns of 86 receivers of hanks.

The ends of the thread held by the thread guide 33 and the hook 43 under the grip are located on the divider 87 of the lever 73, by which the carbon end is separated from the filling end and falls into the mouth of the tongs 88 of the removal mechanism E. Pliers 88 are loosely mounted on pivot 89, reinforced with support ring 22, and are pivotally connected with thrust 90 to lever 80. Lever 80, along with the movement of the knot mechanism, closes clockwise, turns the pincers 88 counterclockwise. With rolls; p1 of the roller 91 along the arc 92 fixed on the supporting ring 22. The forceps close, clamp the carbon monoxide end in their shed and pull it out of the hook 43 of the pickup.

The mechanism of the hub units begins to move in the opposite direction to the initial position up to the stop 93, and the lever 80 rotates 88 clockwise.; 1ke.

Tongs 88 open, enter into the shed of the cleaner 94, reinforced on panel 23, the carbon monoxide end of the filament is removed by a strip 95 from the elasigichnogo mater ala and falls into a collection of waste.

By this time, the crown is approaching the zone of the toothed segment of the ring 17, and the mechanism of the knot units is at the initial position to meet with the next crown, after which all operations are repeated.

The hank receiver has four horns 86. On each horn, the machine discards twenty-five hanks. The counting of the coils discharged from the receiver crowns is performed by a counting mechanism. When the table is rotated 3, the cam of the cam lobes 9 alternately hits the end of the lever 96 of the counting mechanism and gives the latter the pulses for counting the coils lost to the receiver.

When the counter counts twenty-five skeins, the receiver head 97 is rotated one-quarter turn and substituted for receiving the coils next horn.
