Description

Improved yarns take-off device

Technical field

The present invention relates to a kind of yarns take-off device, it uses machine, for example seam loop especially for elastomeric yarn being fed into yarn.

Background technology

For this reason, suitable yarn transfer device has two drive shafts that are parallel to each other and arrange usually, and its upper support has at least one spool of yarn.Described rotating shaft is maintained at and carries in part and by gear drive.Build the gear input by belt pulley, introduced rotation by the rotating band that is arranged on seam loop to belt pulley.For example, in Taiwan patent application No.822 129 59 (TWGM 90131), this type of prior art is disclosed.

Need a large amount of yarn transfer devices to be used for seam loop, and described yarn transfer device is sent to braiding factory as subcontracting part (subcontracted part).In order to distribute yarn transfer device, they usually split being discharged to reach at least them and can encapsulate this degree to save the space mode.They must adopt some manual operations to assemble reliably in the structure position.

Usually, be the multi-piece type member for the rotating shaft that receives spool of yarn.Yet this can adversely affect the concentricity of rotating shaft.Although this impact has any negative results hardly for the sufficient yarn of elasticity, for lacking flexible yarn, the concentricity defective can cause the yarn tension periodic swinging, thereby adversely affects the quality of woven article.

Can be disassembled in order to its yarn feeder that transports also is described in EP 0742304 A1.This printed publication discloses the yarn feeder with double type housing.The lower house shell joint is received the rotating shaft that is provided with bearing and belt pulley, and the upper shell hull shape becomes to be used for the lid of grappling bearing.

Summary of the invention

Target of the present invention is, in order to allow unskilled user can carry out reliable assembly operation, further improves the structure of yarn feeder, and further reduces the packaging volume that transport point needs.The inventor has built an overall goal a kind of yarn feeder is provided, and it has improved function and can make in more economic mode.

These targets are realized by according to

claim

1,19 and 29 described yarn feeders:

According to claim 1,, yarn feeder according to the present invention has two rotating shafts, is used for receiving at least one spool of yarn.Described rotating shaft is to be cylindrical and seamless, jointless member along its whole length direction.This single-piece rotating shaft can be the standard element by the size cutting.For example, it can be formed from steel, and is preferably solidly, but also can be hollow.Described rotating shaft can be provided with along its whole length or only along its outer surface that resistance to wears and/or harden for the outer part that receives spool of yarn.Described rotating shaft is preferably smooth.Described rotating shaft both atresia also without depressed part etc., particularly in the zone that is used for receiving bobbin.This has just guaranteed can not endanger even very meticulous yarn on the bobbin that is received by described rotating shaft.

In the housing that builds as double type approximate horizontal ground dividing member, realized the most simply possibility of assembling.Can not appear at the mistake assembling that may occur in complicated rotating shaft situation.Horizontally separated housing make needn't above the rotating shaft end, ball bearing be inserted in place.Issuable infringement in the time of can not occuring to carry out number of assembling steps in incorrect mode is equipped with pre-assembled bearing because can be described rotating shaft.All these work that need to complete in assembled position are all to comprise that the form of the unit of rotating shaft, belt pulley and bearing is placed in the lower house shell.

Bearing (being preferably ball bearing) preferably remains in described rotating shaft by clamping cooperation or interference fit.For this reason, be provided with pier thick (upset) section in described rotating shaft, it can for example pass through drift mark (punch mark) formation.For each bearing, at least two (being preferably three or four) drift marks are set preferably in each rotating shaft, it is distributed in the even angular distance around the rotating shaft circumference.This just causes forming the good concentricity of described rotating shaft, and allows assembly process in manufactory, ball bearing to be shifted onto not damage in described rotating shaft the rotating shaft surface.Bearing inner ring can have the interior diameter that is slightly larger than the rotating shaft overall diameter.

Further, can described rotating shaft and bearing be assembled by the temperature difference, thereby realize interference fit after thermal balance.In addition, also bearing can be adhered to described rotating shaft.

Preferably include for the bearing that drives described rotating shaft: the first cog belt, it passes to the first rotating shaft with actuation movement from driving mechanism; And second cog belt, it passes to the second rotating shaft with actuation movement from the first rotating shaft.According to preferred embodiment, the first rotating shaft is provided with belt pulley, and it receives two cog belts, and is provided with separator disk between two cog belts, its can by the axially-displaceable position be supported on belt pulley, and be held in place by cog belt.Separator disk can have castellated edge, and it provides and the belt pulley locking-type engagement that forms tooth-profile of gear.Can also make the smooth of the edge of opening.

Gear preferably is connected with described rotating shaft by the ratchet connector, and described ratchet connector can for example be kept continuous connection status by locking ring.The ratchet connector can for example form by one or more ratchet finger, and these ratchet finger are formed on gear, and is projected in the blind hole or similar depressed part that is arranged in rotating shaft.By locking ring, other radial elastic finger can be securely held in the inner radial position, in order to gear forever is connected with described rotating shaft, is used for rotation common with it.

This connection mode is for ease of assembling, and safety, economy.

The use of the restriction of the single gear that is used for two cog belts and separator disk has been represented a kind of height joint space-efficient scheme, and result causes, and housing can be the narrow structures with respect to the axial direction of rotating shaft.Adopt this mode, can realize the saving in cost and space.

As indicated above, the yarn feeder can or drive by CD-ROM drive motor by the band drive pulley.Can design a kind of yarn feeder, it only drives by CD-ROM drive motor from the beginning.Can build housing in alternative, thereby for example make the entrance that has at its downside place for electric notor, and the side place has entrance for the belt drives rotating shaft thereon.This shell type allows to use alternatively the yarn feeder of belt drives or motor driving.In the situation of the yarn feeder that motor drives, preferably in the use of housing downwards towards a side place arrange CD-ROM drive motor.In this position, CD-ROM drive motor does not disturb the operating walk way that leads to bobbin, can not disturb bobbin itself yet.

The CD-ROM drive motor of yarn feeder can be syncmotor, stepper motor, for example permanent type stepper motor or reaction equation stepper motor.In this case, CD-ROM drive motor does not preferably have the position indicator of any type; It is driven in the Open control ring, that is to say, does not carry out any position adjustments.In the situation that contingency stepping error occurs, can tolerate this error as a rule and any problem does not occur.The yarn tension that acts on the yarn roller produces the driving moment of offsetting the stepping error.

If the yarn demand is basically constant, CD-ROM drive motor can be powered with constant frequency by AC power.During start-up operation, frequency can increase to nominal value gradually from zero.In alternative, stepper motor or syncmotor can be equipped with the device of realizing asynchronous starting.This device for example can be and is arranged to short-circuited conducting sleeve or the similar device concentric with the rotation of rotor.

CD-ROM drive motor also can be by the inconstant line voltage operation of frequency.The frequency of line voltage can be used for limiting the different yarn amount of feeding.All CD-ROM drive motors of the identical yarn feeder of a plurality of structures of being arranged in groups on seam loop are driven, to guarantee their operations synchronized with each other by identical AC power.Adopt this mode, central electronic is controlled the frequency that can pre-determine all CD-ROM drive motors.The electronic device that CD-ROM drive motor itself does not just have any type.Adopt this mode, device can be made strong and make in the mode of simple economy.Preferably adapt to concrete running status with the yarn feeder group of synchronizeing or stepper motor is connected by this way.The change of supply frequency is always slowly carried out, so that does not have stepper motor to stop.Avoided transition formula change of frequency.Variation from a frequency to another frequency preferably occurs by the transition of S shape.

CD-ROM drive motor has drive shaft, and its preferred arrangements and drives the cog belt be arranged in housing by the angle driving mechanism in perpendicular, and described angle driving mechanism for example comprises crown wheel, and its crown wheel with the yarn feeder of belt drives is consistent.Adopt this mode, realized higher pitch number.

Crown wheel can be arranged on the outer shroud of ball bearing, and the interior ring of this ball bearing is supported on the pin that is arranged in housing.Adopt this mode, the number that is supported on the rotating shaft in housing is reduced to minimum.This pin can carry member supports by metal, and this carries also support drive motor of member, and it is connected with geometrical clamp or becomes its part.

The cover that claim 23 limits shows a kind of further improvement.Above mentioned cover comparatively expensive and have a larger volume.Encapsulation and transportation also relate to considerable expense.The new cover that is formed by flexible plasticity (or plastics) membrane module can adopt joint space-efficient mode to transport, but also realized its target, although the fact that exists is, during operation, it only covers on the spool of yarn that is received by the yarn feeder basically, and makes the front side of spool of yarn freely movable.For example the protuberance of 20mm can be enough to prevent that the fine hair that pours down is deposited on spool of yarn in weaving factory.Further can provide plane institution movement, be used for spool of yarn is covered in its end.This class A of geometric unitA can be by guide supporting, and this guide rail is laterally extending below housing.Alternatively or additionally, this type of part can be connected with cover, or can be supported on housing separatedly.

Plastic membrane is preferably transparent, to guarantee that spool of yarn is carried out free visible observation.On the contrary, the housing of yarn feeder is preferably opaque, and is preferably few fiber.This scheme is especially economical, and can form level and smooth upper surface, thereby makes device not need paint to be coated with.The stability of geometrical clamp can also obtain by the angulation sheet metal member of introducing subsequently, and as first first mentioning, described sheet metal member can additionally be used for fastening motor.Hardware also can be removed the heat that is produced by motor.

In the situation that drive the yarn feeder by belt pulley and rotor axis mechanical, preferably the tumbler gear device can be set.For example, this tumbler gear device can by the input rotating shaft that can vertically move or by in the input rotating shaft that coordinates with crown gear movably pinion it is driven.If crown gear has each tooth of even number, the axial length of pinion surpasses the diameter of crown gear, direction of rotation can be switched to inverted running from the forward direction operation, crown gear is instantaneous to be disengaged or it is rotated and needn't make, and needn't will rotate during switch step and introduce spool of yarn.

Further advantageously, be connected with the earth conductor that additionally reduces the fine hair deposition tendency with described rotating shaft and/or with all parts of yarn formation contact.

Further advantageously, on housing away from an end place signalization lamp of geometrical clamp.Signal lamp can the misdirection function, such as yarn breakage etc.In a preferred embodiment, arrange at least one from the flashing diode as signal lamp.This has just realized the demand value higher than sustained radiation light source.
