Description
Technical field
The present invention relates to a kind of sample wrapping machine, its with: warper drum, this warper drum has rotation axis and circumference, is circumferentially provided with conveyor surface, and these conveyor surfaces can be parallel to rotation axis and move；Yarn guide equipment, this yarn guide equipment has at least one yarn guide, described yarn guide can shift between operating position and resting position, in operating position, yarn guide is directed to yarn on the circumference of warper drum, in resting position, before yarn guide is directed to yarn the end face of warper drum, wherein, warper drum and yarn guide equipment can relatively rotate with respect to each other, and are provided with yarn furling mechanism on the end face of warper drum.
Background technology
This sample wrapping machine is such as known by EP2284304B1.Here, yarn furling mechanism is rope or line or monofilament.
Sample wrapping machine is used for producing so-called pattern chain or short chain.At this, yarn is wound around the circumference of warper drum and is placed on conveyor surface.Conveyor surface is such as the conveyer belt surrounded.Form the circumference of the usual simultaneously wound warper drum of multiple yarns of so-called band.When reaching the length desired by pattern chain, the band of winding just staggers such that it is able to wind a new band with rolled with recipient place.In order to form predetermined yarn jacquard weave, it is possible to make each yarn depart from from winding process.Then make corresponding yarn guide shift for this, thus before yarn guide is directed to yarn the end face of warper drum.Yarn is then no longer placed on the circumference of warper drum, and is located in reel for yarn and receives in mechanism.Yarn furling mechanism has significantly smaller circumference compared to warper drum, although thus yarn continues winding, but each revolution of yarn consumption keeps significantly smaller.
In past development over several years, for formed the yarn of pattern chain with more and more.Can wind at present such as up to 128 one threads simultaneously.If there is a large amount of yarn to depart from from warping process and be wound up into yarn furling mechanism in this case simultaneously, just has obvious pulling force here and be applied on yarn furling mechanism.If yarn furling mechanism is rope or line, then these pulling force often cause rope to pull out from the region of rotation axis.This causes the stress of alternation of yarn, and the structure of pattern chain is had a negative impact.In addition there is rope risk of fracture when reaching certain load.
Summary of the invention
It is an object of the invention to, even if number of yarns is numerous also can realize good winding quality.
For the sample wrapping machine of type described in the beginning part, the implementation of described purpose is, yarn furling mechanism is divided at least two section, and wherein, a section is retracting section, and a section is conveyor zones.
In this case, these sections are adapted to the task of each of which.Then, retracting section is for winding yarn, and these yarns are at this moment still under certain stress.Retracting section is thus through design so that it can bear the pulling force thus caused.And conveyor zones is for making yarn remove from the end face of warper drum.Yarn can from furling sector transfer to conveyor zones.
It is preferred here that, retracting section is not flexible.Being achieved in the position of regulation, the yarn departed from from warping process is wound in this position.Term " not flexible " means, when the pulling force applied by the stress of yarn is applied on retracting section, retracting section can only in the range of tolerable variance internal strain allowed.
Retracting section is preferably hollow axle, utilizes this hollow axle that yarn feed mechanism is directed in conveyor zones.Thus can adopt in a beneficial way that the conveying function of conveyor zones is in combination with each other with the retracting function of retracting section.Hollow axle can relatively simply design so that it can bear the tension produced by yarn.Then, if yarn is transferred to yarn feed mechanism from hollow axle, yarn feed mechanism will carry stressless yarn to a certain extent without any problems.
Hollow axle preferably has yarn driving clamping device.Yarn driving clamping device such as causes hollow axle to rotate.If rotate warper drum when yarn warping, then hollow axle such as can with the rotational speed identical with warper drum.But not necessarily require so.Under many circumstances, hollow axle is also sufficient to the rotational speed less than warper drum.Can prevent yarn from the stress that hollow axle gets loose as long as ensureing that the yarn being wound up on hollow axle is maintained at.
Yarn feed mechanism preferably rope, band or line.Line can be made up of metal or plastics.In the latter cases, line is preferably monofilament.Rope or belt can be made up of plastics, sometimes with fortifying fibre.
Retracting section preferably has conveying mechanism.Although it is believed that yarn can slide into conveyor zones from retracting section when the certain filling reaching retracting section is spent, if but be provided with conveying mechanism, just can targetedly the yarn of winding in retracting section be transported in conveyor zones.
It is preferred here that, conveying mechanism has feed drive device.Thus it is not limited to the transmission power caused that rotates relative to one another by warper drum and yarn guide equipment.Exactly, it is possible to use feed drive device drives conveying mechanism targetedly.
It is preferred here that, feed drive device has adjustable transporting velocity.By regulating transporting velocity, it is possible to such as consider the various different requirement when winding yarn.Depart from from warping process compared to only having a small amount of yarn, when there being more yarn to depart from from warping process simultaneously, for instance higher transporting velocity can be selected.
It is preferred here that, conveying mechanism has the feed channel around hollow axle stretched spiral yarn shapedly.If yarn enters in this feed channel stretched spiral yarn shapedly, these yarns will be automatically oriented conveyor zones under continuing wound condition and move.If feed channel moves, yarn thus also can move to conveyor zones from retracting section forcibly.
Conveying mechanism preferably has screw thick stick.Screw thick stick such as can be made up of spiral yarn shaped the line stretched or spiral yarn shaped the plastic wall stretched.Then the space between the adjacent turn of screw thick stick automatically produces feed channel.Screw thick stick can be rotatably arranged on hollow axle, in order to making yarn from retracting sector transfer to conveyor zones.
It is preferred here that, feed drive device is the rotating driving device being connected with screw thick stick.Rotating driving device is then applied on screw thick stick directly or through actuating device, in order to screw thick stick is in rotation.This is a kind of relatively simple design, in order to ensure the yarn being wound up on retracting section to be transported in conveyor zones.
Before yarn furling mechanism is preferably supported at the end face of warper drum.In other words, being provided with supporting mechanism before the end face of warper drum, then such as hollow axle and screw thick stick are supported in this supporting mechanism, can also arrange corresponding driving device at this.This this have the advantage that, warper drum and yarn furling mechanism can decouplings mutually.
It is preferred here that, retracting section and warper drum overlap on the direction be parallel to rotation axis.According to this design, retracting section is parallel to the direction of rotation axis and slightly extend in warper drum.Thus avoid yarn and be not wound up into the risk furled on section but be wound up in conveyor zones.
Being preferably provided with release mechanism, this release mechanism makes the separated of the supporting zone on yarn supporting zone on warper drum and yarn furling mechanism.It is stretched over the yarn yarn furling mechanism from yarn guide mechanism and keeps not being subject to the impact of release mechanism.Thus all keep the tensioning state of these yarns all the time, thus thus without producing winding mistake.
Accompanying drawing explanation
The present invention is introduced in conjunction with accompanying drawing below by preferred embodiment.Wherein:
Fig. 1 is the very schematically axonometric chart of the sample wrapping machine with yarn furling mechanism；With
Fig. 2 highly diagrammatically illustrates yarn furling mechanism.
Detailed description of the invention
Sample wrapping machine 1 can also be called short chain warping machine, and it has warper drum 2, and this warper drum is rotatably supported on pedestal 3.During warper drum 2 can utilize the warp thread driving device not being shown specifically to be in rotation or rotate, as shown in arrow 4, warp thread driving device such as can be arranged in pedestal 3.
Being provided with multiple conveyor surface to distribution on the circumference of warper drum 2, these conveyor surfaces can be parallel to the rotation axis of warper drum 2 and move.These conveyor surfaces can be such as the band surrounded, but these bands are not shown specifically.
Except warper drum 2, the bobbin cradle not being shown specifically also is provided with multiple yarn bobbin 5 still, say, that these yarn bobbins 5-under any circumstance in warping process-be fixedly disposed relative to pedestal 3 position.Extracting one thread 6a or 6b out from each yarn bobbin 5, and guided by the yarn guide not being shown specifically, these yarn guides represent with double-head arrow 7 at this.These yarn guides can design in EP1930489A1, and difference is, yarn guide keeps not rotatable relative to the rotation axis of warper drum 2, and the axis that can only be parallel to warper drum 2 moves.
Thus can or as shown yarn 6a be placed on the circumference of warper drum 2, or before yarn 6b being directed to the end face of warper drum 2, if these yarns are for producing temporarily need not pattern chain.
Yarn 6b before being directed to the end face of warper drum 2 is furled by yarn furling mechanism 8.This yarn retracting mechanism supports is in frame 9, thus before position is fixedly placed on the end face of warper drum 2.Yarn furling mechanism 8 at this towards warper drum 2.
Yarn furling mechanism 8 is divided into two sections, and the first section therein is retracting section 10, and the second section is conveyor zones 11.
Retracting section 10 has hollow axle 12, and this hollow axle is rotatably supported in frame 9.Hollow axle 12 is connected (only figure 1 illustrates) with yarn driving clamping device 13, and this yarn driving clamping device drives hollow axle 12 along the direction of rotation of warper drum 2.At this, the rotating speed of hollow axle 12 can be consistent with the rotating speed of warper drum 2.But not necessarily require so.Being sufficient that equally, hollow axle 12 is with relatively low rotational speed.
Hollow axle 12 is not flexible, say, that the pulling force applied by yarn 6 deforms more than predetermined yardstick insufficient for hollow axle 12.This scale selection must be less so that significantly not unbalance or eccentric.
Yarn feed mechanism 14 traverse hollow axle 12.Yarn feed mechanism 14 can be rope, band or line.This line can be made up of metal or plastics.In the latter cases, it is preferred to use monofilament.Yarn feed mechanism 14 can also such as strengthen with fiber such as glass fibre or carbon fiber.Yarn feed mechanism 14 is from deposit roller 15 uncoiling, and is wound up on retracting roller 16.
Hollow axle 12 rotatably supports screw thick stick 17.Screw thick stick 17 is supported on hollow axle 12 with relatively small gap.Screw thick stick 17 such as can be made up of spiral yarn shaped the metal wire bent or plastic cord.Screw thick stick 17 has multiturn, forms feed channel 18 between these circles.Screw thick stick 17 can utilize feed drive device 19(only to figure 1 illustrates) it is in rotation.Feed drive device 19 such as can pass through toothed belt wheel 20 and be connected with screw thick stick 17.Correspondingly, feed drive device 19 can be rotating driving device.Feed drive device 19 preferably has adjustable transporting velocity.
If yarn 6b is wound up into yarn furling mechanism 8 from yarn bobbin 5, then first these yarns arrive on hollow axle 12 in retracting section 10, as it has been described above, this hollow axle can't substantially deform.Correspondingly, hollow axle 12 keeps aliging with the rotation axis of warper drum 2, this, bias that yarn 6 does not occur like because of yarn furling mechanism 8 or vibration.
At least when yarn 6b is wound up on yarn furling mechanism 8, the conveying mechanism being configured to screw thick stick 17 is in work.If screw thick stick 17 rotates, then yarn 6b moves along the direction of arrow 21.The speed that yarn 6b moves along the direction of arrow 21, i.e. transporting velocity, it is possible to relevant to the quantity of the yarn 6b being simultaneously wound on yarn furling mechanism.But transporting velocity can also keep constant.Then passing through the effect of screw thick stick 17, the yarn 6b being wound up on hollow axle 12 moves on yarn feed mechanism 14.For the purpose of difference, the yarn 6b arriving conveying mechanism 14 is referred to as yarn 22 there, and these yarns are no longer on making it be wound up under the stress on hollow axle 12, and this is mainly due to, and yarn feed mechanism 14 has the diameter substantially less than hollow axle 12.Correspondingly, yarn furling mechanism 14 insignificantly deforming.On the other hand, this deformation also no longer plays a role, because the yarn 22 being wound up on yarn feed mechanism 14 is no longer directly connected with yarn guide (double-head arrow 7).
Yarn 22 extends back into again warper drum from yarn feed mechanism 14.These yarns 22 form the yarn section produced when yarn departs from from jacquard weave process.
It is provided with the release mechanism 23 only symbolically illustrated, in order to make the separated of supporting zone on the yarn 22 supporting zone on warper drum and yarn furling mechanism 8.When yarn feed mechanism 14 is wound up on retracting roller 16, the yarn of disconnection no longer disturbs.
As seen in Figure 1, the retracting section 10 of warper drum 2 and yarn furling mechanism 8 overlaps, thus ensureing that the yarn 6b being no longer wound up on the circumference of warper drum 2 under any circumstance arrives on the retracting section 10 of yarn furling mechanism 8, without directly arriving on the yarn feed mechanism 14 of conveyor zones 11.
According to illustrated embodiment, warper drum 2 rotates when yarn 6a winds, and bobbin 5 position is fixedly disposed.But when when warper drum 2 keeps anti-rotation in warping situation, yarn guide utilizes bobbin 5 to rotate, it would however also be possible to employ shown yarn furling mechanism.
