Description

The known devices for replacing the produced spools with empty ones on ringing machines, made in the form of movably fixed supports on the machine, removing full spools from the spindles simultaneously on the whole machine for their subsequent dumping onto the conveyor, have the disadvantage that they are not very automated and cannot be used on existing machines without significant rework of the latter.

In the proposed device, this disadvantage is eliminated by the fact that it uses mechanisms for automatic lowering of annular strips and lift valves, and a carriage that has a rotary and reciprocating movement movable to the rails using cables and blocks to remove the full and put on empty shpul at the same time machine and device for pushing full bobbins onto the conveyor.

FIG. 1 shows a section through a machine with a device for changing spools; in fig. 2-mechanism for lowering the ring bars; in fig. 3 is the same, 1 cross-section; in fig. 4-mechanism of valve lift; in fig. 5 is the same, front view; in fig. b-scheme of motion transmission to the main shaft and freeing them; in fig. 7-mechanism for the initial removal of the ears from the spindles, bottom view; in fig. 8-drive mechanism for the initial removal of accumulated cobs; in fig. 9 is the same; 1 cross-section; in fig. 10-mechanism arrows for changing the inclination of the carriages; in fig. 11-, longitudinal section; on fi; g. 2, too, in plan view, in section.

The operation of the device begins with the removal of a detachment that is unpredictable, and the mechanism of lowering the annular strips, consisting of a worm gear 2, a worm 1 and sitting with the last on one axis of the sprocket 3 for a chain drive, begins to act first; coupling coupling 5a; zamLo 88554- 2 -

ka coupling coupling 4; the locking spring 5 and the load 6. During the entire period of removal of the sprocket 3, with the help of the chain 7, it receives movement from the main shaft 8 of the machine or some other rotating axis. At the time of completion of the top of the cobs, the ring bar presses the locking spring 5 of the lock 4, as a result of which the load released from the locking spring begins to lower, and the cable associated with the load moves the clutch axially along with to the left to clutch the coupling teeth. MI tooth sprocket 3. As soon as the coupling teeth engage with the side teeth of the sprocket, the clutch begins to rotate at the same speed as the sprocket. Coupler Za sits on the shaft of the screw and then, as the coupling rotates, the worm rotates. The worm rotates the worm gear 2 to 1, and along with the chain and face 9, which rotates, begins to unwind chain. As the unwinding of the penalty occurs, the annular strips are lowered.

After the strips are lowered, lowering is installed on both sides along the frame of the carriage carriage, which holds the clamps for a full null cell with a pull-out bottom for empty ones.

Both carriages 10 (Fig. 1) during operation of the maschine stand on inclined racks // and move along them with the help of steel cables that are bla: -; 12 O; J, the ends are attached to the carriages, and the other to the drums 13 on the main shaft of the mechanism. At the moment when I was working out, the ring bars automatically lowered and the machine stopped. oabotnina1a goes up to the car and begins to rotate the tongue 14 (Fig. 6), on the same axis with which two 1L 16 sprockets are planted. Zvs-, point / 5 transmits the decryption through the chain / asterisk / 7 and the worm 18. And the last one leads movement of the worm gear 19, which sits on the main shaft of the mechanism. The shaft is rotated in one direction, thereby winding the cable from the drums 13 and lowering the carriages. The carriage, receiving a weakening from holding them in the upper position of the cables, under the action of its own weight begins to fall down the inclined stands. On the next steps along the inclined racks of the carriage, the tension levers 20 of the cables are lifted from the position L (Fig. 1) to the Lx position. The tension levers 20 are provided to eliminate the instantaneous load on the cables when the carriages come off the inclined racks and change the direction of their movement (transition vertical movement). The descent from the inclined racks of the carriage, without changing their position, begins to descend vertically until that moment when the 1st coats will enter the grip 21.

The carriages, descending to receive the finished removal, special protrusions on both ends of both carriages put pressure on the subframe, 1st stand to 22 and (fig 4.5) thanks5 to the gear system 23, 24, valve 25 deviate by required angle.

In the areas of possible cases of valve blockage back, over the square 26, on which the valves are attached along the entire machine, is placed a steel belt with protrusion 27, which is moved to the left and right sides. The movement of the strip is achieved by having a bracket on the stand 22 of part 28, which, lowering along with the bench, by its bevel 29 mixes the STRIP and at this moment the protrusions become above the valves, after which the angle can be pushed back to any angle.

The first line of C:;: - from the steel strip is the initial, initial, 1 st lid and free;: the wall is removed at riOMnnui parts 30, located on the cylinder bar with the anti-roll end of the machine.

The initial removal of the ears from the spindles is carried out with ring strips using special strips, which eliminates both the breakage of the threads during this operation and the jumping of the threads from the spindles.

Inside the annular strips 57 (Figs. 1 and 7), along their entire length, two types of scissors are placed, which compress the strips 32 and 33. The purpose of the strips is to raise the cob at the moment of lifting the annular strips. This operation (FIGS. 8 and 9) is performed as follows. At certain intervals from each other, along the entire length of the machine, on the spindled bars, several pieces on each side of the arm shift the two shoulders 34.

As soon as the removal time was reached and the ring bars began to fall automatically, then, in their downward movement, the protrusions 35 of the strip 32 find themselves on the bevels of the vertical arms of the levers 34 n, slide along them, cause the strips 32 and 33 to move one relative to the other in opposite directions. directions x. In the lower position of the annular strips, the bands approach each other to the nodes of the cob nest.

When the ring strips have reached their lower position and the machine automatically stops, the worker makes several turns with the 5G handwheel, and lowers the holtz slips hollow slats (Fig. 2.3), thereby rotating the worm to, which transmits the movement of the heart to the dick, and together with neii 1 p; the circuit drive disk is located on the machine. The chain, winding onto the disc, pushes the annular strips (as is usually done).

When the annular strips are lifted, the bands 32 and 33 abut their sectors into the ears of the cobs, sleep them from the bells of the spindles, and in neck with the coL1, H1e: h; P; plakky1mn ganmamayut E; М-Ь ciiCM input of the cob into the clamps 21 carriage, which firmly capture them.

At the time of entering pochtkgm; N uvashkp kol1, peevye; 1l1p and l: zp1lyuts up, and the protrusions 37 pa band 33 rotate through the stops 55 of the chain 5.9, nalotye on zvzdzdop-si, reinforced pas axles of the levers 34. production turn ple-i of the IGS 90. Io crowds, those who, vertically lower the ring planks vertically, will now move to the horizontal position, and those that were in the horizontal position will move to the vertical position. After that, the same .MaxoEiHMOK 36 g is rotated on the reverse side, and, thus, the ring strips are pushed into the lower edge of the floor to earn a new pickup. At the moment of lowering of the annular strips to the lower position, the protrusions 55 on the strip 32 are located on the vertical bevels. The shoulders of the levers 34 and, sliding along them, cause the strips 32 and 55 to move one along the oTHouiciiino DC drthton NCC around the head of the head:. le1n-1I and move from the middle to their original position (to the edges of the ring bars).

The ring planks, lowering, simultaneously lowering the spindle pa with the remaining coils of the threads in which the coils of the threads, which are further lowered, go down, and therefore fix this end, which is necessary for earning a new removal.

Seeing the order of how the cobs J are entered into the grips of the lower part of the js, then JMiOiHfi; rrl:; 1t pu for ps :). the flywheel / V (Lng. 6) npJULuuoT on the reverse side, and therefore, all the details move opposite to the original, i.e., the worm, the chern gear and the main shaft rip on the back and the cables are wound. The carriages are under the head, but they go along with them; they sit ;, 1e in the hands of N (i.e., c} 1and: 1 the cobs with the spindles), the carriages, pods, i.e., all the cobs when peoborva1 wind the threads from the bottom of the cob to the spindle. As soon as ver. 88554 shows

No. 88554

the spindle tire, the flywheel is rotated in the opposite direction in order to lower the carriage again. When re-lowering the carriage, they change their position from inclined to vertical.

Each carriage (Fig. 10) at both ends has rolls, the top 40 and bottom 41, which fit into the long grooves of the uprights and thus do not allow the carriages to deviate from the masking bar line, moving the carriages vertically.

When the carriages are lowered to receive the cobs, the upper rollers 40 turn over the stops (not shown) supporting the arrows 42 in position B. After the carriage is lifted and released, the latter under their own weight deflect to the position B and with their vertices overlap the long grooves of the racks. This moment just coincides with the moment when the cobs rise 10-20 lsh over the tops of the spindles, after which the carriages are lowered to put the empty spools on the spindle.

During the secondary lowering of the carriages, the upper rollers abut against the overlapped grooves of the arrow and, not being able to move further along the long grooves, are forced to roll along the inclined planes of the arrows 42 into the short grooves of the uprights than force the carriages from the inclined position B to go to vertical i and position to go down to a certain point. Simultaneously with this operation, i E315po: opeoaml iO is attached to the fastening of the threads on the spindles. Since the carriages change their position gradually, together with the lowering of the thread, the threads descending from the base of the cobs do not break, but take off from the wheels, move away from the mashish and fall down. The coils wind tightly around the spindle and settle to the top of the bells of the spindles.

On the sloping racks 11 (supporting carriages), on one side of the vertically standing part (front of the machines), there are tides 43 (Figs. 11 and 12) on which the protrusions 44 of the retractable bottom 45 crawl at the moment of lowering the carriages in a vertical position, moving the retractable bottom to side until the holes in the bottom coincide with the hole in the carriage. As soon as this coincidence occurs, the spools located in the nests of the carriages will lose their foothold and fall on the spindle, fixing the sleeves of threads going to the runner. Thereafter, the sliding bottom is automatically closed by the action of the springs 46 located on the rear side of the carriages.

Upon further lowering of the carriages, they bottom touch the tips of the spools and tightly upset them.

However, the spools can be besieged by carriages only when they are well selected for the level of fit.

After the bobbins fall out, the cobs should be released from As can be seen from the movement transfer diagram of the carriages (Fig. 6), two sprockets 15 and 16 are mounted on the shaft of the handwheel 14, and from the sprocket 16 the chain goes down to the sprocket sitting on the shaft 47, at the ends of which there are worms 48 interlocking with worm gears 49, sitting at the ends of the shafts of the extinguishing frames 54.

In addition, on the shaft, where the handwheel / 4 is located, there are two gear couplings 50 and 51, the coupling 5 / being fixed on the shaft, and the coupling 50, fitted on the longitudinal key, is connected to the spring 52 and can be moved axially.

When the nerve is lowering the carriages, the gear sleeves are not coupled and the gear wheel 16 stands still. When re-lowering the carriages, the handle 53 is released from the anvil and under the action of the spring 52 the gear couplings engage, thereby causing both gears to rotate, i.e. simultaneously with the lowering of the carriages

the rise of the exiting frames 54 running along the whole machine (Fig. 1). As soon as the carriages reach the lower position, the extinguishing frames will stand in a vertical position, and the ejection fingers 55 will show over the cobs. After that, the gear sleeves are disconnected for a short time and the carriages are lifted, while the ears rest against the outgoing fingers standing above them. Upon further raising of the carriages, they can no longer be held in the clips 21, but fall out onto the inclined plane 56 and are squeezed into the conveyor 57. Yes, the heart rate again pull out the handle 5,: from the stop and continue to lift the carriages. In so doing, the expelling frames 54 are lowered to their original position.

Conveyors 57, driven from the main shaft of the machine, feed the cobs on them to the tail end of the machine, dump them into the stand to receive the box simultaneously with the start of the machine.
