Background technique
Carding machine sliver is made from fibrous material in the carding machine, and subsequent carding machine sliver is further processed into yarn.However,
Supatex fabric can also be made instead of carding machine sliver.In these cases, carding machine is usually associated with hopper, hopper by
Conveyer belt system supply with the fiber from blowing room.Fiber is conveyed in the form of Soft flocks.Hopper is continuously or logical
Control on demand is crossed from transportation system filled with Soft flocks.In most cases, using pneumatic conveyer system.From hopper, fiber
Bits are introduced into carding machine by means of the feeding device of fiberfill form.Into carding machine fiberfill uniformity in cotton carding
It plays an important role in terms of the service life of the operation element of machine and the requirement being placed on carding quality.Carded web or by carding machine
Uniformity of the uniformity of the supatex fabric of generation also by the fiberfill for entering carding machine is influenced.In carding process
Another important technology factor is the weight into the fiberfill of carding machine.The amount and fiberfill of fiberfill weight enter
The admission velocity of carding machine substantially determines the output of carding machine, and be for realizing specific carding quality auxiliary because
Element.It can be determined by the mach fiberfill weight of cotton carding or by product to be processed.
Feed roller for continuously pulling Soft flocks from the hopper to cooperate with feed well is arranged in the lower part of hopper, or
In the design of alternative type, it is arranged in the lower part of skewed slot.The Soft flocks pulled by feed roller from hopper are via vent roll
It is fed into feeding-passage, for carrying out additional opening and homogenizing.In feeding-passage, Soft flocks are by means of compressed air
Forming, to form the uniform fiber filler for being suitable for feeding carding machine charging.A kind of fan is additionally provided, the fan and feeding device
It is associated and can realizes in feeding-passage pressure increase and therefore Soft flocks is made to be compacted into fiberfill.Due to fan
The pressure generated in feeding-passage, Soft flocks are compacted into fiberfill.It flows through fan and enters the air warp of feeding-passage
It is extracted out from feeding-passage in its end by ventilative wall and returns to fan.
From the charging according to the carding machine known in the state of the art of 693 419 A5 of CH, wherein Soft flocks are from deposit hopper
The feeding-passage (feed well) of carding machine is discharged to via feed roller and vent roll.In hopper, the air flowed through is applied to
Fibrous matter.Air outlet slit opening is provided at the lower end of hopper, air leaves hopper by air outlet slit opening.Hopper
Section be designed to adjust in air outlet slit opening.One disadvantage of such design is impossible equably and automatically
Ground adjusts the density or fill level of the fibrous matter in hopper.
The another type of design of feed hopper for example discloses in 706 658 A1 of CH.That disclosure shows one kind two
Part hopper comprising upper skewed slot and lower skewed slot.Upper skewed slot be filled with Soft flocks, subsequent Soft flocks by feeding device from it is upper tiltedly
Slot is transported to lower skewed slot.Soft flocks are transported to carding machine from lower skewed slot in the form of fiberfill, which passes through charging
Channel is supplied from the downstream of lower skewed slot, and the device for influencing fiberfill is not provided with inside feeding-passage.Feeding-passage is only
Fiberfill is transported to carding machine from lower skewed slot.One of such design is the disadvantage is that, being transported to comb for fiberfill
Before cotton machine, it is impossible to equably and automatically regulate the density or fill level of fibrous matter in feeding-passage.
Summary of the invention
Therefore, the purpose of the present invention is to provide a kind of feeding device, fiberfill in feeding-passage is automatically adjusted
Compacting and fill level, so that carding machine be made to be capable of supply that uniform fiberfill.
It is another object of the present invention to the fill level in the working width upper feeding channel for adjusting carding machine, so as to
Realize the constant and uniform charging of fiberfill to carding machine.
The purpose is realized by the feeding device of the feature with independent claims.
Be proposed that it is a kind of for fibrous material to be fed into the device of carding machine, with hopper, hopper discharge dress
It sets, the fan of feeding-passage and the fiberfill weight for the fibrous material in feeding-passage to be compacted to restriction.Hopper row
Device has the feed roller by transducer drive out, which has for measuring the charging from the fibrous material that hopper occurs
Slot and vent roll for fibrous material to be transmitted to feeding-passage from feed roller.There is provided a kind of control system, wherein fan
The corresponding special fiber filler weight of setting point pressure and different fiberfill weight in target volume flow and feeding-passage
Amount is related.Device for pressure measurement is provided in feeding-passage.Control to the fiberfill characteristic of feeding-passage downstream end is
It is conclusive, because the uniformity into the fiberfill of carding machine is important.The air being introduced by fan in feeding-passage
It is discharged from fan via the ventilative part of the feeding-passage in feeding-passage downstream end.If feeding-passage is now by fibre
Material filling is tieed up, then fibrous material is had to pass through to reach the ventilative portion of feeding-passage downstream end by the air that fan introduces
Exist respectively.Thus fibrous material is compressed by air.The compacting of fibrous material is bigger, and the resistance for being subjected to the air-flow from fan is got over
It is more.Amount of compaction determines the fiberfill weight for being compacted into the fibrous material of fiberfill.Therefore, fiberfill weight is by fibre
It ties up material and resists the resistance decision for flowing into air.The compacting of fibrous material depends on the fiber for being applied to the air introduced by fan
The pressure of quality, the compacting of fibrous material is for realizing that fiberfill weight is conclusive.Due to this dependence, it is specified that
The pressure of the air-flow in feeding-passage is introduced by fan.
By changing the fill level in feeding-passage, the fibrous material of bigger quality is forced air over, to reach
The ventilative wall of feeding-passage.Therefore, the fill level in feeding-passage has volume of air flow and significantly affects.Pass through tune
Section volume of air flow correspondingly sets the fill level in feeding-passage.
Various types of fibers and its blend are processed in carding machine.Their special properties are different, such as material
The ratio of different fibers in (cotton, synthetic fibers, viscose glue etc.) or fibre length (such as short or in fold) or fiber blends.It is based on
Fibrous material, output to be achieved and the requirement being placed on carding quality to be processed establishes and is suitably used for carding machine
Charging fiberfill weight.Spinning expert sets the fiberfill weight of fibrous material to be supplied based on their correlation experiences
Amount.The set-point value of pressure in feeding-passage and the volume flow of fan are stored in the control system for various fiber mat weight
In system.The device for pressure measurement being arranged in feeding-passage makes it possible to the speed by controlling feed roller and therefore controls reach
The amount of the fibrous material of feeding-passage keeps scheduled setting point pressure.On the other hand, the fill level in feeding-passage is logical
Influence volume flow is crossed to define.
Change in output-production of such as carding machine increases-more fiberfill are discharged to from feeding-passage
In the case where in carding machine, lead to the horizontal reduction in feeding-passage.Usually by directly control the delivery rate of feed roller come
Compensate such case.Although directly controlling, in case of the reduction of fill level, then the amount of the air drag from fan is subtracted
It is small, and therefore, below the pressure reduction to setting point pressure in feeding-passage.The speed that control system passes through increase feed roller
This point is responded, to restore to set point pressure.
Advantageously, fiberfill Weight control is provided in the controls.In order to control fiberfill weight, control system
Determine the actual value of fiberfill weight.It is known from the prior art to determine actual fiberfill weight；For example, EP 2 867
392 A1 describe such method.If had differences between scheduled target fibers filler weight, it is based on the difference,
On the one hand it is assigned with the volume flow of fan and the set-point value of pressure, is on the other hand assigned with actual fiberfill weight,
When keeping the set-point value of fan volume flow, the set-point value of pressure is corrected.This is because fiberfill weight
Correction need to change the pressure in feeding-passage.However, it is possible to the filling water of the remaining feeding-passage determined by volume flow
It is flat.
The actual value of fiberfill weight is by means of carding machine sliver produced or weight, the carding machine of supatex fabric
The calculating of output quantity of total draft and deposition determine.Each fiber of fibrous material parallelization and is knitted in carding machine with non-
The form for making fabric or carding machine sliver leaves carding machine.In this process, fiberfill is opened, so that the cotton carding of production
Machine sliver leaves carding machine with the bigger muzzle velocity of the admission velocity entered in carding machine than fiberfill.This process is known as
Drawing-off.This drawing-off occurs on the multiple rollers being arranged in carding machine.The each drawing-off occurred from roll-to-roll can add up to
The total draft of so-called carding machine.The total draft and the total draft for knowing carding machine from the mode of operation of carding machine are by apparatus control
It itself determines.The total draft of carding machine corresponds to the entrance of the muzzle velocity and fiberfill of carding machine sliver or supatex fabric
The ratio of speed.Become by the driver at the entrance and exit of control carding machine and from the control for being output to respective motors
Amount, equipment control device determine the speed of motor, and it is thus determined that the roller by motor driving peripheral speed.Enter for determining
Other of speed or muzzle velocity device include the measuring device of such as rotation speed of roller or axis.Pass through the cleaning of fibrous material
And parallelization, pollutant and staple fiber are removed from the fibrous material in carding machine.The system ingredient removed from fibrous material claims
For waste.Amount of waste can be by means of being determined based on the waste function of output.Usually by measuring different productions by rule of thumb
Under the conditions of and using different fibrous materials amount of waste come it is primary determine machine type and fibrous material to be processed waste function.
For example, the measurement of the sliver weight in carding machine exit passes through the clamping of measurement disc-type roller or the radiation for measuring supatex fabric
Measuring system carries out.
Preferably, fan has the driver with frequency converter, and frequency converter is for controlling motor speed.In this way,
Fan can directly be set as new set-point value by control system.It, can as the substitution of the driver controlled with frequency
To provide control gear or control device in the air inlet/outlet conduit of fan.In order in the entire of feeding-passage
Being uniformly distributed for fibrous material is realized on width, it is necessary to establish new speed set point value.When on the working width in carding machine
When seeing, the uneven distribution of fibrous material leads to the irregular fiber filler in feeding-passage.In this case, due into
Expect the hole of fiberfill or marginal laceration occur at the outer end in channel, fiberfill weight will not on the entire width of carding machine
It is identical.This may also cause the reduction of possible output, or in the case where the up-regulation of fiberfill weight, cause charging logical
Excessive fiberfill weight in the central area in road.Volume of air flow in feeding-passage has an impact to fill level.?
Under some cases, due to forming exhaust passage into the fiberfill in the ventilative region of feeding-passage wall from feeding-passage,
Excessive volume flow can lead to the uneven compacting of fiberfill.
Provided that the sensor of the opening for measuring feed well is also advantageous.It is removed from hopper by feed roller
Soft flocks density or compactness also have an impact to the fiberfill formed in feeding-passage.In highdensity situation,
The gas permeability of fibrous material reduces, and reaches the lower fill level in feeding-passage under identical pressure set point value.
However, it is all unsatisfactory in all cases to compensate this phenomenon by adjusting the pressure in feeding-passage, because stagnating
Adjusting lead to the excessive reaction time, this may cause the obstruction of feeding-passage in the case where fill level temporarily rises.
In the case that high-density fiber in hopper is considered to be worth doing, feed well is caused to be opened with feed roller removal Soft flocks.As needed, it feeds
Slot is flexibly supported and is opened or closed by Soft flocks.Pass through the sensor of detection charging groove location and with due regard to controls feed roller
Speed, can quickly identify the variation of Soft flocks density.This allows to reduce charging when feltwork bits occur, thus
Prevent the blocking of feeding-passage.The construction of sensor can be distance measuring sensor or displacement measurement (for example, inductance or capacitance kind
Type) or angular sensor, design and/or its movement corresponding to feed well.
On the contrary, if the density of Soft flocks is reduced charging can be increased by increasing the speed of feed roller, thus anti-
Only feeding-passage is dallied due to insufficient supply.Consider that the density of Soft flocks makes feeding-passage by the opening of measurement feed well
It can have short construction.
Further it is proposed that a kind of device, it can be independently of the fill level in fiberfill Auto-regulating System of Density of Heavy Medium feeding-passage.
Device for fibrous material to be fed into carding machine includes feeding-passage and fan, which is used for the fibre in feeding-passage
Dimension material is compacted to the fiberfill weight of restriction.Fan has the driver for having the frequency converter for speed control or is used for
Control the control device of volume flow.Filling sensor is provided in feeding-passage to measure fill level.Filling sensor can
To be embodied as single sensor or multiple sensors.It must ensure the uniform of fill level on the entire working width of carding machine
Property.It is contemplated that sensor construction example include optics or production quantity sensor.For the reason related to construction, due to several
What shape, for all types of applications of specific feeding-passage design, specified fill level (set-point value) is identical.
Volume flow control is advantageously provided, calculates wind compared with target fill level from the fill level of measurement
Fan the correction of the position of speed or control device.Due to built-in feeding-passage, target fill level can be used as fixed value and go out
Now in the controls.Alternatively, which can also be determined by the installation site of filling sensor, so that filling water
Flat measured value leads to the difference of direct measured value and target fill level.
Further it is proposed that a kind of carding machine with the device for supplying fibrous material, wherein the device is more than
Description is to implement.
Further it is proposed that a kind of method for supplying carding machine specific quantity fibrous material, wherein fibrous material is from charging
The hopper of roller is transported in feeding-passage, which cooperates via the vent roll in feed roller downstream with feed well, and is being fed

Pressure, and based on the setting point pressure in feeding-passage compared with actual pressure, by means of Frequency Converter Control feed roller
Driver, while keeping required volume flow.
Advantageously, while keeping target volume flow, the distribution for setting point pressure is based on selected fiberfill weight
It is influenced by fiberfill weight control device.Due to passing through ventilative area of the fiberfill from feeding-passage to feeding-passage wall
Domain forms exhaust passage, and the excessive volumetric flows of air can lead to the uneven compacting of fiberfill in feeding-passage.Preferably,
The variation that point pressure is set due to caused by the fiberfill Weight control with constant target volume flow passes through feed roller speed
The corresponding adjusting of degree is to compensate.Carry out adjustment speed by means of frequency converter associated with driver or control gear.In addition, advantageous
, in order to keep fill level, target volume stream is realized by the speed or the position of control device that accordingly adjust fan
The compensation of amount.
Furthermore it is advantageous that with the opening of sensor measurement feed well.It is therefore possible for the detected that the opening of feed well can be excellent
Selection of land is used as the correction factor of control feed roller.This causes charging logical for preventing due to the variable density of Soft flocks in hopper
The purpose of blocking or insufficient supply in road.
