Definitions

  • the present invention relates to a weaving machine for producing a fabric with shedding means for alternately lifting and lowering of warp material for forming a shed, with arranged in a weft insertion position fixed weft insertion means in the warp to insert a preferably band-shaped weft material in the shed, and with withdrawal means for removing the finished Goods in a deduction direction. Furthermore, means for goods movement in the warp direction are provided, by means of which the edge of the goods in a goods movement range between a downward starting position and an upward pick-up position is reciprocable to bring in the pick-up the last registered shot material with the edge of the goods in contact.
  • the JP 2003-253547 A1 therefore proposes to use a fabric movement for tissue formation instead of a conventional weft stop.
  • a pair of rollers is provided, between which the edge of the already finished fabric is clamped.
  • the pair of rolls with the clamped edge of the fabric is moved counter to the withdrawal direction to the newly entered weft material in order to bring it into contact with the fabric edge of the fabric.
  • rotation of the rollers enters the last registered weft material between the two rollers of the roller pair and is clamped by this.
  • the pair of rolls with the newly created, clamped edge of the fabric is moved back to the starting position.
  • Object of the present invention is therefore to propose a weaving machine, which reduces the risk of damage to the weft material.
  • a loom for producing a fabric includes shedding means for alternately lifting and lowering of warp material for forming a shed, in the warp direction fixed in a weft insertion zone arranged weft insertion means for introducing a preferably band-shaped Weft material and withdrawal means for removing the finished product in a withdrawal direction.
  • the weft insertion zone is defined here by the stationarily arranged weft insertion means or the leading and trailing edges of a ribbon-shaped weft material that has just been introduced.
  • means for goods movement in the warp direction are provided, by means of which the edge of the goods in a goods movement range between a downward starting position and an upward pickup position is reciprocated to bring in the pick-up the last registered shot material with the edge of the goods in contact and a To achieve a vocation.
  • the terms relate upwards and downwards in each case to the take-off direction, so that correspondingly the downward starting position is closer to the goods removal means than the upward pick-up position.
  • upper and lower in the warp direction movable limiting means are provided, which limit the shedding caused by the shedding means opening of the shed and which within a Begrenzungsffenschuls Kunststoffs Kunststoffs back and forth between an upward and a downward end position and are movable.
  • the product or the warp material is guided between the upper and lower limiting means in the direction of the withdrawal means.
  • the limiting means are in this case at least in the movement against the withdrawal direction without jamming, i. without actively acting contact on the goods and a last registered shot material movable.
  • the limiting means surround the last registered shot material or the goods thus only loosely, so that they protect the weft material in a particularly gentle way from undesirable deformations.
  • top and lower limiting means are moved from a downward end position counter to the withdrawal direction into an upward end position, wherein the limiting means are moved without jamming without active contact to the goods or the last shot material inserted over the goods or the weft material.
  • the weaving shed opening by the action of the shed forming means is limited by the limiting means, with the last inserted weft material being between the limiting means, and subsequently the edge of the newly inserted weft material newly formed and the limiting means become substantially synchronously with each other moved back to the starting position or the downward end position.
  • Damage to the weft material which could arise in the prior art when pulling the last registered weft material in the clamping region of the two rollers are avoided according to the invention in that at least during the movement against the withdrawal direction or during a relative movement between the goods and the last registered shot material and the limiting means no active clamping and thus no direct contact is provided, but the goods or the edge of the goods and the last registered shot material are only loosely surrounded by the limiting means.
  • the movement of the limiting means on the goods and on the last registered shot material is thus largely contactless, while in the prior art, a fixed clamping of the weft material or a clamping was provided.
  • means in the context of this invention means are meant by which the distance of the warp material in the compartment opening direction can be limited at least in the region of the edge of the fabric.
  • a deleterious effect of the warp threads on the last inserted weft material is prevented by the limiting means which limit the opening of the shed which is predetermined by the shedding means.
  • the last registered shot material is between the limiting means and a propagation of the opening of the shed is prevented by the limiting means, the last registered shot material remains in a straight, extended state and can not be deflected by the warp threads.
  • the limiting means in this case protect the newly entered weft material against deformation by the opening shed until it is picked up by the contact with the previous edge of goods from the weft insertion zone and transported away in the direction of the withdrawal device.
  • a wavy deformation of the weft material still present in the weft insertion zone, which prevents the production of a desired flat fabric and also causes further damage to the weft material or the fabric, can thus be avoided.
  • the Begrenzungsffenschis Colours Council is different from the goods movement range, preferably greater than the goods movement range executed. This makes it possible, for example, to place the last inserted weft already completely between the upper and lower limiting means and thus to protect, before it is moved in the withdrawal direction.
  • the limiting means are first moved substantially synchronously with the movement of the edge of the goods from the starting position to the pick-up position from its downward end position into an upward intermediate position. Only after the edge of the goods has reached the picking position, the limiting means are moved to the upward end position, wherein the limiting means are moved in the warp direction over the last shot material entered. Subsequently, the edge of the fabric and the limiting means are moved substantially synchronously with one another in the drawing-off direction back into the starting position or the downward end position. The last registered, initially still in the weft insertion zone located shot material is thus only picked up or moved in the withdrawal direction when it is completely between the limiting means and thus protected from deformation and damage. In a correspondingly designed loom, the weft insertion zone is thus substantially within the boundary means movement range.
  • the weft insertion position is substantially outside the Begrenzungsffenschuls Kunststoffs Kunststoffs Kunststoffs.
  • the limiting means are first moved substantially synchronously with the movement of goods from the starting position to the pick-up position from the downward end position to the upward end position. Subsequently, the goods movement is already started back to the starting position, wherein the last registered shot material between the limiting means is withdrawn. Only after the last inserted weft material is completely retracted between the limiting means, the limiting means are moved synchronously with the edge of the goods from its upward end position in the withdrawal direction back to the downward end position.
  • the edge of the fabric after he has reached the picking position is held in a temporary standstill and only then moved back to the starting position.
  • the goods movement means in the pick-up position are correspondingly durable in a temporary standstill.
  • the limiting means may be maintained in one or more arbitrary positions within the limiting means movement range in a temporary standstill.
  • the limiting means in order to assist the alignment, it is advantageous for the limiting means to be durable in a temporary position located substantially downwards of the weft insertion zone and / or in the upward end position in a temporary standstill.
  • the limiting means in the intermediate position or in the upward end position are advantageously kept in a temporary standstill during the product standstill.
  • a further improvement of the Vertuchung can also be achieved if after closing the closed or already reopening shed is held in a temporary shutdown or the movement of the warp material is kept in the shed opening direction in a temporary standstill, at least until the limiting means their Have reached upward end position and / or the last registered shot material has passed between the limiting means.
  • a temporary standstill ie a temporary stoppage of the movement of the warp material in the compartment opening direction, is made possible according to the technical standard. This makes it possible to spend the last registered weft material still in the field, possibly already tied off easily, in the protection zone between the limiting means and thus to protect at any time before a deflection and undulating deformation.
  • the shedding means for this purpose shafts with elongated Litzenaugen, so that no interference with the continuous movement of the shedding means are required.
  • the Litzenaugen are hereby extended so that there is a shutdown for at least 1/36 the duration of a weaving cycle.
  • the weft material after the weft insertion as long as both sides of the warp material clamped in clamps until it completely, d. H. has passed over its entire width to its trailing edge between the limiting means.
  • the weft material can thereby be protected at any time before deformation by the warp material.
  • the limiting means comprise two strips extending in the weft direction. These can be designed as mutually fixed strips and surround the weft material thus at any time only loose.
  • the limiting means are designed as clamping means.
  • the limiting means for this purpose have two strips extending in the weft direction, wherein at least one of the strips is movable in the vertical direction in order to clamp the weft material. The weft material is thus positively clamped during the entire tissue formation and its transport in the withdrawal direction and protected against deflection and wave formation.
  • the spacing of the strips is adjustable in order to allow adaptation to the thickness of the processed material or the resulting fabric.
  • the vertical spacing of the strips is adjustable during weaving operation.
  • an adjustment is possible at any time, without interrupting the process.
  • the distance of the limiting means during the movement of the limiting means is reduced after reaching the upward end position. As a result, a particularly good protection of the last registered weft material can be ensured in a gentle manner, with no risk of damage to the goods by a direct, clamping contact.
  • a further in the warp direction between a front and a rear end position movable reed is provided, wherein the front end position of the reed relative to the withdrawal direction upwards or behind a trailing edge of the last registered, located in the weft insertion zone Shot material is or has just reached.
  • the function or the movement of the limiting means and the correct removal of the weft material from the weft insertion zone is monitored by means of suitable sensors in order to avoid collisions with the weft insertion means and defects in the tissue formation.
  • Fig. 1 shows a loom 1 according to the invention in a schematic side view.
  • the weaving machine 1 includes in a known manner a warp beam 2, from which a warp material 3 is provided, shedding means 4 for forming a shed 5 and weft insertion means 6 (not shown here, see Fig. 6 Alternatively, the warp material may also be provided by a gate having a plurality of warp coils from which the warp material is peeled off. Furthermore, take-off means 8 for removing the finished product 9 in a withdrawal direction AR (symbolized in the present case by an arrow) are provided.
  • the warp material 3 can be designed in a conventional manner thread-like or else band-shaped.
  • the warp material 3 is guided by the warp beam 2 in a conventional manner via a coating tree 10 through the Litzenaugen 11 of the shedding means 4, which are presently designed as shanks, and which form the shed 5 by changing lifting and lowering of the warp material.
  • the warp material 3 converges in the binding point 12 of the fabric, from where the finished product 9 is fed to the withdrawal means 8 via a breast tree 13.
  • the weft insertion means 6 are arranged stationary with respect to the warp direction and define a weft insertion zone 14, the width of which with respect to the warp direction in each case corresponds to the width of the weft material used.
  • tape-shaped weft materials 7 would be damaged by a conventional weft stop, it is provided to effect a Vertikung by a movement of goods.
  • the means 10, 13 for movement of goods are presently formed by the breast tree 13 and the coating tree 10, which are synchronously reciprocable in the warp direction and forth, as indicated by the dashed line and the double arrows.
  • the means 10, 13 for goods movement could also be formed by reversible discharge means 8 in conjunction with a reversible drive for the warp beam 2.
  • a movement of the fabric edge 12 could also be realized by a superposition of a movement of the breast tree 13 and the coating tree 10 on the one hand and the discharge means 8 on the other.
  • the edge of the fabric 12 is in its starting position AG, which is downwardly in relation to the withdrawal direction AR, and is movable counter to the withdrawal direction AR into an upwardly disposed collection position AH, where it is brought into contact with the last inserted weft material 7.
  • the goods movement means 13, 10 are moved in the withdrawal direction back to its initial position shown in solid lines, wherein the newly inserted at the trailing edge of the last shot material 7 fabric edge 12 back to the starting position AG is spent, and the product 9 is withdrawn in a known manner.
  • band-shaped weft materials 7 Another problem in the processing of band-shaped weft materials 7 is a wave-shaped deformation of the weft material. 7 This wave formation not only hampers the formation of a desired uniform and flat fabric 9, but can also lead to problems and damage, in particular of the protruding weft material 7, in further processing or withdrawal of the fabric. The wave-shaped deformation further leads to a pulling in of the band-shaped weft material 7 from the two lateral fabric edges in the direction of fabric center, so that the formation of the lateral goods finish is impaired. According to the present invention, therefore, upper and lower limiting means 16 are provided, between which the warp material or the finished product 9 is guided to the take-off means 8.
  • the limiting means 16 are reciprocable in the warp direction between an upward end position EP2 and a downward end position EP1 and are thereby able to project the last inserted weft material 7 already in the weft insertion zone 14 and during its entire removal from the weft insertion zone 14 an undesirable deflection by the warp material 3 and damage to protect. It is particularly advantageous in this case that at least the movement of the limiting means 16 against the withdrawal direction AR, ie the "picking" of the weft material 7 without jamming, ie essentially without direct contact with the weft material 7 and the goods 9, so that the risk of damage of the weft material 7 is reduced.
  • the goods movement means 10, 13 and the limiting means 16 are formed as independent assemblies, for example, as well as Fig. 1
  • the limiting-device moving range extending between the up-and-down end positions EP1 and EP2 is made larger than the goods moving range WB.
  • the limiting means 16 can be moved directly into the weft insertion zone 14, to pick up the registered shot material 7 there.
  • the limiting means 16 is preferably by means of a separate drive 21 (see Fig. 6 ) can be driven independently of the goods movement means 10,13, so the movements can be particularly flexible adapted to the particular shot material used 14 and other conditions. In particular, a completely independent timing of the movements of the goods movement means 13 and 10 and the limiting means 16 is possible.
  • FIG. 3a - 3e A representation of a method for producing a fabric and the movement of the limiting means 16 and the goods movement means 13, 10 is in Fig. 3a - 3e shown in a schematic side view.
  • Fig. 3a shows here the situation of the goods movement means 13 and the limiting means 16 immediately after the weft insertion. Relative to the main shaft of the loom 1, a situation at about 290 ° machine angle is shown. The shed 5 is just open at this time or begins to close. The band-shaped weft material 7 has been introduced by weft insertion means 14, for example a gripper, and is now located in the weft insertion zone 14. The edge 12 (and accordingly the goods movement means 13, 10) is located in the downward starting position AG and the limiting means 16 at this time are in their downwards end position EP1. Furthermore, a reed 15 is shown, whose function will be explained at a later time.
  • the limiting means 16 are at this time in an intermediate position ZP, which connects downstream of the weft insertion zone 14 to this.

  • the edge of the fabric 12 located in the pick-up position AH is now held in a temporary standstill in order to allow the diversification. It is particularly advantageous in this case if, during the goods standstill, the limiting means 16 in the intermediate position ZP are temporarily held in a temporary standstill in order to support the diversification. The limiting means 16 are then further moved from the intermediate position ZP counter to the withdrawal direction AR in the direction of their upward end position EP2, as indicated by the arrow in the Fig. 3c indicated. Fig. 3c This shows the situation shortly after closing the shed 5, which takes place at about 350 ° machine angle.

  • the shed 5 begins to open again, wherein the now completely between the limiting means 16 located shot material 7 is protected from undesired deflections and damage by the warp material 3.
  • the limiting means 16 have reached their upward end position EP2 at about 370 ° or 10 ° machine angle.
  • the opening of the shed 5 after reaching the suMedices is delayed by maintaining the closed shed 5 in a temporary standstill until the limiting means 16 have reached their upward end position EP2.
  • Undesirable effects of the weft material 7 by the warp material 3 can thereby be avoided in an advantageous manner already at a time at which the weft material 7 is not yet completely in the protection zone between the limiting means 16.
  • Fig. 3e shows the situation shortly after the start of the movement back to the starting position AH and the end position EP1, which starts at about 20 ° machine angle.
