Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for driving a dosing system in a carding machine that can change the operating speed of the dossfer system in a carding machine between a low speed range and a high speed range without impairing operability, and This relates to a drive device.

In recent years, with the demand for rationalization of the spinning process, high-speed carding machines with dosing speeds of 3 Orr and 0 m or more have been developed in the carding process.

In addition, in conventional carding machines, the maximum speed of the carding machine is about 15 r, p, m, but by modifying this carding machine, the speed can be increased to about 2 or, p, m. Tend.

However, the speed of the hill is 2Or, p1
If the sliver becomes too crowded during operation, it is impossible to work on the sliver, so the dosing speed is set to 15 r.
The vehicle must be decelerated to below p and m.

Moreover, in order to improve operability, a simple transmission system had to be provided.

For this reason, in the past, it has been necessary to select, for example, the force of two sets of pulleys with different gear ratios, from take-in to dump-event IJ-.

The high-speed operation of the Dotsufa system was accompanied by low-speed operation.

That is, as shown in FIG. 1, the cylinder 1 is 1. IK
It is driven by a W cylinder motor 2 via flat pulleys 3 and 4 and a flat belt 5.

The take-in 611 is driven by the cylinder shaft via the pulley 7.8 and the flat belt 9, and rotates synchronously with the cylinder 1.

Further, the fly comb 10 is driven from a cylinder shaft via a pulley 8.degree. 11.12 and a belt 13.14.

Further, the feed roller 15 and the ramp roller 16 each have a plate bevel 17. Side change bevel 18.
It is driven by a doffer shaft via a side shaft 19 and a microphone foil 20.

Further, the calender roller 22 is driven once by a dosing end wheel 25 via a calender roller end wheel 23 and a carrier foil 24.

Note that the calender roller 22 does not drive the coiler.

Dotsufa 21 is compound carrier foil 26.27
It is driven by a take-in shaft via a change wheel 28 and a transmission 29.

The pulleys 32 and 33 are driven by boots 30 and 31 which are inserted into the shaft of the pickup 6 through belts 34 and 35.

Further, the pulleys 36 and 37 are arranged coaxially with the pulleys 33 and 32, respectively, so that the pulley 36 rotates synchronously with the pulley 33 and the pulley 37 rotates synchronously with the pulley 32.

The dandy pulley 38 is attached to the pulley 3 by the belt 39.
It is possible to connect it with 6 or 37.

In section h, the belt 39 is now moved by the belt shifter 40.
When the force 1 is applied in the direction of arrow A to connect the dandy pulley 38 and the pulley 36 (the state shown in Figure 1), the pulley 21) rotates at a low speed, and the dandy pulley 38 is moved in the direction of arrow B by 1. When the docker 21 is rubbed so that it connects with the IJ-37, the doffer 21 rotates at high speed.

Configuration: Since the cylinder motor 2 is the only motor that drives the carding machine, the cylinder system and carding system must be operated in synchronization even at the start of operation.

Unless the sliver is cut due to an accident, the sliver is never cut and therefore no work is required on the sliver date.

However, on the other hand, the cylinder motor does not have enough power to cope with the increased speed of the dosing machine 21, and as a result, the dosing speed becomes unstable and unevenness occurs in the web, and there is also the risk of the motor burning out. It had the disadvantage of being

Therefore, in order to eliminate the defect F, the cylinder motor 2 is separated from the cylinder motor 2 as shown in FIG. 1it) A pole number changing motor 41 is provided to drive the doffer base once, and the doffer base is driven into two high and low positions via a pulley 42 and a belt 43.
A method is being considered to drive the vehicle at speed ζ In this way I'
The load on the cylinder motor 2 does not increase, but rather decreases, and the speed of the doffer system (1), which is driven by a separate motor, can be stabilized.

However, on the other hand, the doffer system and cylinder system do not operate in sync.

At the start of operation, the sliver was already broken, and there was a drawback that work had to be done to attach the sliver.

Further, the normal dosing speed is up to 2 Or, p, m
Even in the case of so-called semi-high speed carding machines, the number of machines held by one worker is as large as 10 to 30, so at the start of operation
In this case, the sliver mouthing operation must be carried out, which has the drawback of extremely poor operability and a significant drop in operating rate.

The disadvantages of the present invention are as follows: All of the drawbacks mentioned above have been overcome, and the dosing speed is stabilized, and there is also a margin for increasing the speed of the cylinder motor, without impairing operability. The present invention provides a method and device for driving a docker system in a carding machine I, which changes the speed of the doffer system between a high speed range and a low speed range.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 3, cylinder 1111. It is driven by an IKW cylinder motor 2 via a flat pulley and a flat belt.

The take-in 6 is driven from the cylinder shaft via a flat pulley and a flat belt.

Rotates synchronously with cylinder 1.

The fly comb 10 is driven by a cylinder shaft via a pulley and a belt.

The feed roller 15 and ramp roller 16 are each driven by a dosing shaft via a plate bevel, a side change bevel, a side shaft, and a microphone foil.

The calender roller 22 is driven by a dotted end foil 25f via a calender roller end foil and a carrier foil, and the coiler is driven by the shaft of the calender roller 22.

In addition, a 0.4KW 6-pole dosing motor 44 for driving the dossfer system 1 is provided separately from the cylinder motor 2; pulley 48
is connected to.

Further, an overrunning clutch 52 is provided on the shaft g81 of the doffer motor 44, an inner race of the overrunning clutch 52 is inserted and fixed onto the shaft l of the doffer motor 44, and a pulley 51 is fixed on the outer race I. .

The seventh pulley 51 is inserted into and fixed to the shaft through the belt 50 and connected to the single pulley 49.

The above-mentioned overrunning clutch 52 (1) Power is transmitted from the outer race to the inner race.

In the opposite direction, from the inner race to the outer race, power is not transmitted and the wheels spin idly.

Note that it is also possible to use a clutch that does not transmit power in one direction, such as a one-way clutch, in place of the overrunning clutch 1.

The docker 21 is inserted and fixed at its shaft by a dandy pulley 48, and is driven via a change wheel 28, a compound carrier foil 26, 27, and a dosfer end wheel 25.

In other words, in the configuration described in Section 7, the die-dye pulley 48 and the pulley 46 are as shown in FIG. 4A.

It is also possible to connect a belt 55 formed of cone pulleys 53 and 54 and movably arranged by a belt shifter 40, etc., and by this rubbing, the F-' speed can be changed from the lowest speed to the lowest speed. The maximum speed can be changed steplessly up to 1, or the maximum speed can be changed to 2 Or, p,
It is also possible to freely select I within the range of rrr-3Or, p, and m.

As shown in Figure 4, Dandy Pulley 4
8 and pulley 46 may each be formed of two-stage pulleys 56 and 57, and connected by a belt 55 arranged movably by a belt shifter 40 or the like. It is also possible to change the

In the seventh configuration, when the carding machine is started, when the cylinder motor 2 is turned on, the cylinder 1 starts rotating, and the checker in 6 also starts rotating via the pulley and belt.

At this time. Since the dotsfa motor shaft 44 is stopped, power is transmitted to the dotsfa motor shaft from the pulley 49 provided on the take-in shaft via the overrunning clutch 52, and the power is transmitted to the dotsfa motor shaft l by the pulley 46 provided on the dotsfa motor shaft f. Dotsufa 2 after 48
1 is rotated synchronously with cylinder 1.

Fly comb 10. Feed roller 15. The wrap roller 16 and the calendar roller 22 also rotate in synchronization with the cylinder 1.

Normally, when the cylinder 1 is operating at a steady speed, the boot IJ-51 is rotating at a speed of about 60 Or, p, m, and the doffer 21 is rotating at a slow speed of 10 r, p, m.

At this time, if the sliver is cut, the date on the sliver will be used.

Next, when the switch of the doffer motor 44 is turned on, the doffer motor 44 is turned on at 120 Or
, p, and m, the driving force of the pulley 51 is cut off, and the rotation of the pulley motor 44 is stopped at IJ-.
46, transmitted to dandy pulley 48, dotsfa 21
rotates at a high speed of 20 r, p, m.

Furthermore, if you wish to return the dotsfer 21 to low speed rotation,
When the switch of the doffer motor 44 is turned off, power is again transmitted to the doffer drive system from the pulley 51, and the doffer 21 rotates at a low speed of 10 r, p, m.

When the carding machine is stopped, the switch of the cylinder motor 2 is turned off. If the carding machine is rotating at high speed, the switch of the doffer motor 44 is also turned off at the same time, and the doffer motor 44 is synchronously decelerated. Similarly, during low-speed rotation, the cylinder 1 and the dropper 21 are synchronously decelerated.

This one piece. The web did not break, and the carding machine stopped due to the 22f calender curler being untidy.

In this way, the dolpher drive system (4 dolpher motors 44
Turn on the power, run it at high speed, and turn it off.
Drive at a slower speed.

Further, when starting the carding machine, the cylinder motor 2 is started first, and the dosing motor 44 is not powered on.

Since the present invention has the configuration described above, when the carding machine is stopped, when the power to the carding machine is turned off, the cylinder drive system will stop while rotating due to inertia, regardless of whether the carding machine is running at high or low speed. Since the drive system also stops while rotating in complete synchronization with the cylinder drive system, the sliver does not break.

Also. If the carding machine is started in this state, the sliver will not be cut at all because the docker drive system and the cylinder drive system rotate completely in synchronization.

When the cylinder drive system that started the carding machine reaches almost steady operation, turn on the power to the carding motor.
Since it uses a clutch that only transmits power in one direction, as soon as the motor reaches a certain number of rotations,
I: The clutch operates, and the Dotsufa drive system smoothly shifts to high-speed operation.

In this way, the dosing motor drive system smoothly transitions from high-speed operation to producing sliver of good quality without causing web unevenness, and without any loss in operability. Since the cylinder motor and the cylinder motor are provided separately, each motor has a large margin and can be operated at a stable speed, which has a very large effect.
