Description

The present invention aims at the flaxing machine tape currently collected in the basins, winding it up onto rolls under pressure and, after reaching a certain winding length, automatically shut off the load, release and roll out the roll, tear off the end, feed the end of the tape to wind the new roll and turn on the load .

In the drawings of FIG. 1 is a front view of the device; FIG. 2 is a general side view; FIG. 3-view of the coil winding and release mechanisms (side view); FIG. 4-view of a mechanism for pushing out levers with discs and sleeves for winding coils; FIG. 5 is a sectional view of the discs and sleeves for winding and a mechanism for pushing them apart (top view).

The proposed device consists of the following. On the frame adjacent to the card machine and consisting of three sidewalls connected by cross links (Fig. 1), bearings 1 are installed, in which roller 2 is located. Two arms 3 are articulated on it, bearing axles 4 at their ends, on which conical sleeves 5 rotate with disks 6 mounted on them (Figs. 1 and 5).

(180)

Sleeve 5 is a two-stage cone, one step of which is reinforced with needles, and the second step is smooth (Fig. 5).

The levers 3 are pivotally connected with the levers 7, the other ends of which are put on the fingers 8 screwed into the bevel gear 9. The gear 9 is seated on the finger 10 screwed into the roller 2 and meshes with the gear sector 11, also located on the roller 2 (Fig. 5).

The cylindrical part of the toothed sector 11 engages with the rail 12 mounted in the guides and bearing the finger 13 (Fig. 3).

Fork lever 14, pressing on the finger 13, mounted on the shaft 15, located in the bearings. On the shaft 15, the lever 16 connected by means of the earring 17 to the one-arm lever 18 carrying the roller 19 is wedged. The latter contacts the eccentric 20 sitting on the shaft 21. On the same shaft there is an eccentric 22 which is in contact with the roller of the two shoulders brake 23 having as the lever 16, the axis of rotation 24. On the long arm of the lever 23, a load 25 is suspended. With a short shoulder, the lever 23 is connected to a brake band 26, which is mounted on a brake disc, which rotates freely on the shaft 28 (Figs. 1 and 2). The hub of the brake disc goes into pulley 27, on which chain 29 is strengthened, the second end is connected to lever 30 wedged on roller 2. Asterisk 31 wedged on shaft 21 is in periodic engagement with roll 32 fixed between discs 33 sitting on shaft 34. Gear 35 with cams and cam coupling 36 sits on the same shaft.

Gear 35 is kinematically associated with gear 37 wedged on a shaft 28, bearing on itself also a grooved cylinder 38, gears 39 and 0, and a cam clutch 41 (Fig. 1).

The gears 39 and 40 are connected by means of a toothed device to a roller gear, at the end of which an asterisk 42 is wedged, connected to a Gall chain with an asterisk 43, which sits on the shaft of the exhaust cylinder of the card machine.

Support arms 44, interconnected by pedal 45 and attracted to the frame by springs 46 (Fig. 2), are loosely seated on shaft 28.

A shaft 47 may be attached to the shaft 47 with a gear that engages with the gear 48, which sits on the end of the shaft 34. On the same shaft there is a gear 49, which causes the counter drive disk, which rotates on the axle 51, (fixed in the holder 52, on the upper end of which is fixed pointer 53 of Fig. 1 and 2).

The proposed device operates as follows. At the beginning of the process of winding the roll, the levers 3 with bushings 5 and discs 6 are lowered to the lower position in which the smooth steps of the conical sleeves contact the rubber rims of the corrugated cylinder 38, leaving a small gap between the reinforced part of the conical sleeves and the surface of the corrugated cylinder.

The corrugated cylinder 38, which receives a uniform rotation through a gear and a Gall chain from the lower exhaust cylinder of the cardmachine, transmits friction through the contact with the smooth steps of the tapered bushings, to the rotation of the discs.

The tape from the exhaust cylinders of the cardmachine, through the guide visor, enters the gap between the reinforced part of the sleeves and the surface of the corrugated cylinder, is caught by the needles of the sleeves and begins to wrap around them, forming a roll, which creeps along the meter. As this roll grows, the disc arms lift upward, turning roller 2.

The required pressure on the coil is achieved by the fact that the entire system of levers and discs is pressed in the process of winding to the grooved cylinder 38 with the aid of the lever 30 stuck on the roller 2.

Levers 3 with discs 6, lifting as the coil winds up, turn the roller 2, and with it the lever 30, the end of which, lifting, tends to lift the chain, in which develops a force equal to the force needed to overcome the braking moment .

This force is transmitted through the levers 3 but the normal between the roll coiled and the grooved cylinder 38.

Upon reaching a certain winding length, the load is automatically switched off by means of an eccentric 22, with its protrusion lifting lever 23 with a load of 25 and thereby unloading the brake, and hence the chain.

As soon as the brake is unloaded, the eccentric 20 enters into action, with its protrusion lifting lever 18. At the same time, the end of the lever 16, pivotally connected to the lever 18 by means of the earring 17, rises. Lift, the lever 16 rotates the roller 15, and with it rotates the stuck on this roller fork lever 14.

The latter presses on the fingers 13 of the rail 12 and raises it. The rake rotates the cylindrical gear sector 11 when lifting. This also rotates the bevel gear 9, which is in engagement with the bevel gear sector 11. The levers 7 press down on the levers 3, cause them to turn, causing the discs 6 to diverge.

When the discs diverge, the rail 12 for some time, is supported by the lever 14 in the upper position.

At this time, the released roll

rolls onto the trough and levers with discs fall from their own weight. In this case, the conic gear 9, being in engagement with the currently fixed conical toothed sector I, is forced to turn on the finger 10, as a result of which the levers 3 with the discs 6 return to their previous position.

The conical sleeves 5 come into contact with the grooved cylinder 38 and drive the disks 6 into rotation. The load is automatically activated due to the protrusion of the eccentric 22 coming out of contact with the roll of the lever 23, allowing the lever to tighten the brake band.

The section of tape connecting the roll-up roll to the exhaust cylinders is then wound up by the needles of the sleeves and automatically cut off, and the section finally rolls off the tape that starts to wrap around the conical sleeves to form the next roll.

Following the fall of the disc levers, the protrusion of the eccentric 20 comes out of contact with the lever 18, allowing the latter to lower and lower the end of the lever 14 down.

The rail 12, being engaged with the cylindrical toothed sector I, remains in the upper position.

When a new roll is formed, the levers 3 and the discs 6, and together with them the whole pushing mechanism, begin to rise, turning around the axis of the roller 2. At the same time, sector II, which is in engagement with the bevel gear 9, rotates and gradually lowers the rail 12 down.

When the roll reaches a predetermined length, the leash 13 of the slats 12 will almost close to the end of the lever 14, which, by lifting, will again push the levers 3 with the discs 6.

In order to prevent the levers 3 and the discs 6 from starting to fall, and, consequently, to move earlier than the finished roll rolls down onto the trough, a device consisting of a pedal 45 connected to the supporting levers 44 located on the shaft 28 is arranged. During coiling of spring coil 46

the support arms 44 are attracted to themselves. The fingers 3 are screwed into the levers 3, which, lifting together with the arms 3 as the coil winds up, squeeze the support arms 44 to stretch the spring 46.

At the last moment, before the end of winding the roll, the fingers drop into the upper pads of the levers 44, which are adjusted to their original position by the springs 46.

When the levers 3 are moved apart, the fingers of the latter slide along the upper pads of the levers 44, making it possible for the roll to roll freely. Rolling out, the roll hits the pedal 45 and knocks out the supporting levers 44 from under the fingers, so that the levers 3 with the disks 6 are able to fall, turning around the axis of the roller 2. If it is necessary to remove the incomplete roll, turn off the counting mechanism, moving cam clutch 36, whereby gear 35 will rotate idly. Then, lifting the handle 47, turn the roller 21, an eccentric 22 is mounted on it with a collar, the protrusion of which, entering the contact with the roller of the lever 23, automatically unloads the roll. Then they lift the levers 3 until their fingers move to the upper p and arms of the levers 44. At this time, thanks to the lifting of the levers 3, the rail 12 is lowered to its extreme position.

After this, the handle 47 is rotated until the zero division of the dial of the counter 50 coincides with the fixed pointer 53. At the same time, the projection of the eccentric 20 will split the discs. This position of the counter corresponds to the beginning of the winding of each roll.

Due to the possible tightness in the manual roll change process, it may be necessary to wind the accumulated tape continuously out of the exhaust cylinders. To this end, the gear train, which transmits rotation to the shaft of the corrugated cylinder from the lower exhaust roller of the cardmachine, is designed in such a way that when you turn on the knocker 41 to the right, the shaft of the corrugated frame

The required number of turns ensures that the coil has a normal winding speed. When switching the clutch to the left, the shaft receives the number of revolutions, which provides the possibility of faster winding. In the middle position, the clutch is disconnected from the gears and the whole device is turned off.
