Abstract

Two groups of weft shuttle magazines are configured for one double bar Rachel loom in order to manufacture spaced knitted fabrics for which the surface is reinforced through attached warp and/or warp. Two groups of longitudinal conveyors (13h, 13v) are subject to the two groups of the weft shuttle magazines. The two groups of longitudinal conveyors (13h, 13v) move mutually in opposite movement direction (36h, 36v). Moreover, the two groups of longitudinal conveyors (13h, 13v) pass horizontal yarn feeding areas (14h, 14v) placing the weft in turn, then pass the slightly oblique feeding areas (15h, 15v), strongly oblique first returning areas (16h, 16v), finally pass the other returning areas (17h, 17v) of the longitudinal conveyors (13h, 13v). The invention is characterized in that the movement rails of the two pairs of the longitudinal conveyors (13h, 13v) mutually pass and form one puncturing area (38). Moreover, the movement rails of the two pairs of the longitudinal conveyors (13h, 13v) cross at a deflection position (39h, 39v) between the slightly oblique feeding areas (15h, 15v) and the strongly oblique first returning areas (16h, 16v). The crossing position is located on a knitting position of the double bar Rachel loom. The compact building mode is realized through the design, wherein the weft can be conveyed to the knitting position in a larger speed through the weft shuttle magazines, thus the double bar Rachel loom with the building mode has higher production speed.

Technical field

The present invention relates to a kind of double-needle bed raschel type warp knitting machine that is used to make knitted spaced fabric, this double-needle bed raschel type warp knitting machine has a knitting position, on knitting position, warp thread, stocking yarn and the pile yams that imports sley point cooperates with the knitting needle on its opposite and formation and export the space fabric width of cloth that is produced between two sley bars, this warp knitting machine also has the Weft feeding device that leads to the zone between the pin row of sley point and knitting needle in both sides, knitting position, wherein, weft yarn is inweaved the upper strata of the knitted spaced fabric that produces in its feedway one side respectively.

Background technology

For a long time, knitted spaced fabric with the title of " wool spinning " by known; It is made up of two tissue layer, and these two tissue layer interconnect by pile yams.The manufacture method of double-deck high pile knitted fabric is by known, wherein, the velvet knitted fabric is cut off and produced to webs along the longitudinal by a kind of band cutter of cutting, and known also have the application (referring to the company brochure of LIBA machine Manufacturing Co., Ltd relevant double-needle bed raschel type warp knitting machine DGDPLM) of complete knitted spaced fabric aspect clothes, furniture overcoat, mat lining and knitmesh.In clothing system, knitted spaced fabric can be realized the adjusting (showing the report of Melliand-textiles, the 818/819th page referring to K.Machowa, G.Hoffmann and C.Cherif) to micro climate.

In addition, also recommended to have the engineering knitted spaced fabric on the double jersey surface of two reinforcements, wherein, knitted surfaces is known as coverage rate.Two reinforcement forms by body warp and/or warp thread, and they are supplied to knitted fabric extraly; Here, trellis is always favourable.Coverage rate will so just have produced so-called interval insulant or sandwich on will being supported and fixed at interval by pile yams.The Application Areas that is worth emphasizing especially is construction material and cement products, and such as the light divider wall with knitted spaced fabric, it is used as sandwich plate, referring to A.Roye and Th.Gries in " putting into practice " 2004 the 3rd phases the 26/27th page argumentation through fabric.

Also mentioned the unitary system fabrication technique of double-needle bed raschel type warp knitting machine in the argumentation above-mentioned, it is used as the scientific research purposes and is taken into account as prior art in this application.The special character of this double-needle bed raschel type warp knitting machine is its knitting unit, wherein, respectively is provided with a weft yarn feed element in the both sides of knitting position, and this element is used to introduce 90 ° of rove.In the argumentation of A.Roye and Th.Gries, relevant schematic diagram and brief literal all can not guarantee the reliable inference of the ins and outs of applied weft yarn feed element herein.

For the warp knitting machine that is used for making in batches flat fabric, in the system of so-called shuttle magazine, in knitting position, carry the process of weft yarn by known.Here, advancing weft yarn is placed on the vertical conveyer belt of ring-type arranged in pairs (in general being chain) and temporarily remains there.Weft yarn can be used as to be stretched yarn beam or the wall scroll yarn grown and flows to vertical conveyer belt continuously, perhaps temporarily deposits as endless yarn bundle or wall scroll yarn, and for this reason, thread-carrier can use in conjunction with the displacement rake.The shuttle magazine system allows the warp knitting machine of so design with higher speed operation.

Warp knitting machine for above-mentioned form, such as warp knitting machine according to DE 198 16 440 C1, the weft yarn that vertical conveyer belt and vertical conveyer belt are placed above is sent to the knitting position of warp knitting machine in the horizontal direction, and conveyer belt empty after unloading weft yarn send up to its turning and to feedback not having to continue transmission on the horizontal direction that changes.Body warp is from top conveying and be passed down through knitting position sideling, and wherein, the finished product flat fabric also at first has same direction, and prerequisite is that it passes warp knitting machine and carries and transport out again from warp knitting machine.Above vertical conveyer belt of carrying through knitting position, also be furnished with the sley point that has warp thread, preset flat (ibid, particularly Fig. 4 and Figure 10) and below vertical conveyer belt, placed the pinhock, flat of locking upset and the weft yarn that are used for sliding pin movably.The warp knitting machine that is used for making this known construction form of flat fabric has been proved in practice and can have been realized higher output in continuous running reliably.Yet, by there is the problem in the bigger design at a lot of moving-members of knitting position region clustering; Uncertainly be how known form of implementation, the form of implementation that particularly has a weft yarn shuttle magazine can be considered and be used for making more economically knitted spaced fabric.

Summary of the invention

Therefore, task of the present invention is, proposes a kind of double-needle bed raschel type warp knitting machine of above-mentioned form, this warp knitting machine be suitable for producing and in continuing to produce with higher operating rate and preferably reliability realize the manufacturing of high-quality knitted spaced fabric.

Above-mentioned purpose realizes by the double-needle bed raschel type warp knitting machine of globality.Therefore, so be provided with at double-needle bed raschel type warp knitting machine, respectively arranged the weft yarn shuttle magazine that has line feeding device and have the vertical conveyer belt of a pair of ring-type in both sides, knitting position, wherein, the weft yarn that is placed on vertical conveyer belt by line feeding device flows to knitting position continuously, like this, two pairs of vertical conveyer belts have opposite traffic direction, its moving track in vertical plane operation pass in opposite directions in some zone and the knitting-bit set of double-needle bed raschel type warp knitting machine on the edge in puncture zone, wherein, this zone is surrounded by two pairs of vertical conveyer belts.

For all there are two pairs of vertical conveyer belts of annular according to double-needle bed raschel type warp knitting machine of the present invention, its moving track passes mutually in some zone.Vertically conveyer belt runs to the knitting position that is positioned on the puncture edges of regions respectively with opposite traffic direction.Therefore, realized the prerequisite of compact mode of construction, can also on performance, settle reliably at necessary equipment of the function of knitting process and single assembly.

According to favourable form of implementation, vertically the moving track of conveyer belt has an inflection point in the puncture zone, and its meaning is to move down with bigger angle of inclination." move down " expression with bigger angle of inclination, being tilted on the traffic direction of moving track continues to increase.Moving track turns down to a certain extent; If it already tilts, it is afterwards stronger to be tilted in inflection point.The moving track of two pairs of vertical conveyer belts should be just in this inflection point or an intersection of turning back, and wherein, inflection point is positioned at the knitting band of position.

According to further useful design, each vertical conveyer belt all at first has the yarn feeding zone of a level in succession in its direction of motion, in this yarn feeding zone, placed weft yarn, be the feeding zone that tilts slightly with respect to horizontal direction in the above, at this is already mentioned inflection point above zone, is the first loopback zone with respect to the horizontal direction strong tilt then.Inflection point is positioned at the knitting band of position, and wherein, vertically conveyer belt intersects at inflection point.

By this special layout, just the layout that has a down dip to the machine mediad of chain branch two-stage has produced an enough construction space at sley bar on the one hand, has also produced enough spaces at the placement of sinker holding seat on the other hand.If weft yarn from top conveying, is undoubtedly favourable for knitting process.Like this, weft yarn moves with approximate direction of doffing, and so also makes cutting be more prone to, and this is because the weft yarn of two machine zone alternately moves relative to the cutting direction.Equally, Wai Bu weft yarn also can easily be transported to knitting position by this way.

For according to of the present invention, its vertical conveyer belt double-needle bed raschel type warp knitting machine in the running of yarn feeding zone level, if feeding zone with respect to the angle of inclination of horizontal direction between 6 ° to 20 °, preferably between 10 ° to 14 °, again be preferably 12 ° and the first loopback zone with respect to the angle of inclination of horizontal direction between 35 ° to 55 °, preferably between 40 ° to 50 °, be preferably 45 ° again, this is proved to be is favourable.Under the situation that machine support arm parameter changes,, can change these values if regional owing to other reason tilts such as feeding.

For the moving track that makes two pairs of vertical conveyer belts can pass on a vertical plane in opposite directions, be provided with in an advantageous manner, a pair of vertical transport tape has littler spacing than another to vertical conveyer belt.

In addition, in order advantageously to implement knitting process, for form of implementation very favourable according to double-needle bed raschel type warp knitting machine of the present invention be, be positioned at the knitting-bit weft yarn guide plate of having put the regional arranged beneath of each vertical conveyer belt feeding in zone, on this weft yarn guide plate, carry the weft yarn of coming to wind up, be elongated and be tauted; Here advantageously, below the weft yarn guide plate, sinker holding controllably moves back and forth, and this sinker holding is used as the weft yarn furnisher simultaneously by means of the yarn clipping hole.

Be when single knitting process finishes, to carry out unwinding reliably and simultaneously weft yarn accurately is transported to knitting position, by what this set can be realized even if operational structure space is very little.

For according to double-needle bed raschel type warp knitting machine of the present invention, select correct knitting needle to have special meaning.Particularly advantageously be, knitting needle is designed to have the latch needles of elastic force needle latch, and therefore, the needle latch of latch needles always is coupled with pretension to lighter open position by the elastic force effect.In the travelling forward of latch needles, the elastic force needle latch is so handled by the capture broken end rove steel wire that is positioned on the sinker holding, and promptly needle latch always opens far away reliably.The effect of elastic force needle latch is that needle latch takes off from syringe needle after unwinding automatically.By taking off needle latch, needle latch capture broken end rove steel wire more close, especially deeper be arranged into the pinhock place.This design is another the important design that realizes simple mode of construction.

Favourable also has, and one side is arranged a segmenting device respectively at the edge of knitting position, and this segmenting device was cut apart the weft yarn of two pairs of vertical conveyer belts in the moment that knitting process need be cut apart.This segmenting device can be a kind ofly to cut apart plate or can also be a kind of segmenting device of heat effect according to the difference of stocking yarn material.What play a decisive role is respectively to have a segmenting device just enough on the edge at two pairs of tricot width of cloth that vertical conveyer belt produced.Here, the weft yarn of two pairs of vertical conveyer belts is alternately and in the diverse location and the segmenting device effect of segmenting device.

At last, for the driving of vertical conveyer belt advantageously, each vertical conveyer belt is by the driven by servomotor with planet transmission behind the torque-converters of itself, and wherein, vertically turning back of conveyer belt realized separately by linkage.On the whole, this has caused driving that can accuracy controlling and has saved ground, space and transmit vertical conveyer belt.By the specific drive means that cloth is provided with a kind of draw-out roller group form that goes out for the knitted spaced fabric of manufacturing, intricately carries for twice weft yarn no longer to be associated with the cloth that goes out of the tricot width of cloth, wherein, in going out in the cloth process of the tricot width of cloth, two weft yarn groups are summarized in the cover-up surface.

28h, 28v.

To describe knitting process below, knitting process is supplied with realization with described knitting implement in conjunction with the weft yarn 11h, the 11v that realize from both sides on knitting position 10.In addition, Fig. 5 to Fig. 7 has described other stage of knitting process.

As mentioned above,

weft yarn

11h, 11v are not to keep identical

vertical conveyer belt

13h, 13v speed to realize to the conveying of knitting position 10.Vertically

conveyer belt

13h, 13v more should periodically quicken and delay time.Acceleration realizes in the process that forms mesh, so that subsequently weft

yarn

11h, 11v are transported to knitting position 10 in time.On the contrary, at latch needles 28h, when 28v comes off, affiliated

vertical conveyer belt

13h, 13v are delayed time, and therefore weft

yarn

11h, 11v subsequently lags behind, so that needle latch 29h, the 29v of

latch needles

28h, 28v have enough spaces to realize closed process.Therefore,, also can come work by the distribution of fixture (fixed cover hook) closely on

vertical conveyer belt

13h, 13v even vertically the speed of

conveyer belt

13h, 13v is higher, and also less by the waste material amount of cut weft yarn afterbody generation.

Weft yarn

11h, 11v arrive weft
