Definitions

  • the invention relates to a weaving machine consisting of a reed reversibly adjustable between the shed position and the beat up position and positioned on a stringer of a batten, which is a member of a multimember mechanism, the stringer of the batten is fixed on the frame of the weaving machine using at least two flexible members.
  • the invention further relates to the batten of the weaving machine for positioning the reed and for transmission of a reverse motion of a drive on the reed and the batten consists of at least two leaf springs.
  • a reverse motion of a reed is in known weaving machines realized by reversible rotation motion due to positioning of the reed on a swinging batten, which is a member of a multimember mechanism.
  • the batten of the weaving machine is composed of a swinging device, on which the reed is positioned, while there is a requirement for a rigid and firm connection of the reed with the batten and sufficient torsional and flexural rigidity of the batten and the reed.
  • the batten is composed of a swinging tube pivoted in the frame of the weaving machine and coupled with a driving device, while the batten represents the outer member of the multimember mechanism.
  • the swinging tube On the swinging tube are firmly fixed slay swords, on which is fixed a carrier of the reed.
  • the drawback of this solution is the mass distribution in the section of the batten because the carrier of the reed in particular distinctively increases the inertia moment of the whole batten or if you like the system of the batten and the reed, while the share of this carrier in increase of torsional and flexural rigidity of the system of the batten and the system of the reed is minimal.
  • a weaving machine consisting of a reed reversibly adjustable between the shed position and the beat up position and mounted on a stringer of a batten, which is a member of a multimember mechanism
  • the stringer of the batten is fixed on the frame of the weaving machine using at least two flexible members, whose principle consists in that the flexible members are arranged in two parallel planes with distance between them in direction of the movement between shed position and a beat up position.
  • the reed positioned on the stringer of the batten performs a translation motion, whose considerable advantage consists in that the reed does not lean but in principle maintains the same position while moving between its shed and beat up position.
  • the advantage of this solution is a significant reduction of the batten weight and a change from a reverse rotary motion of the stringer of the batten to a reverse translation motion. That provides a significant reduction of a reduced inertia moment of the weaving machine, which allows an increase of frequency of the reverse translation motion of the reed over the limit of the frequency of reverse swinging motion of the reed of up-to-the-date known weaving machines, while reducing the noise and reducing the energy and the power output for the driving the batten.
  • the principle of the batten of the weaving machine according to the invention consists in that it contains at least two leaf springs arranged in two parallel planes with distance between them in direction of the reversible movement of the batten.
  • the batten is represented by a body, which can be easily inserted into the weaving machine.
  • Fig. 1 to 10 are shown various arrangements of a batten of a weaving machine with a reed in a beat up and picking position, while from the other parts of the weaving machine is schematically shown a warp, a shed creation and a fabric.
  • Fig. 11 is shown an axonometric projection of arrangement of the batten according to the invention.
  • a beam 1 and a batten 2 of a weaving machine mounted on it is shown.
  • the beam 1 or a part of the batten 2 corresponding to the beam is mounted on the frame 3 of the weaving machine, while the frame 3 is shown only schematically.
  • On the batten 2 is positioned a reed 4 , while the part of the batten 2 , on which is fixed the reed 4 is coupled with a connecting rod 51 of a driving device 5 , which is mounted on the frame 3 of the weaving machine, From the other parts of the weaving machine is schematically shown a warp 6 , creation of a shed 7 on the Fig. 2 , 4 , 6 , 8 and 10 and a fabric 8 .
  • the batten 2 a member of the multimember mechanism, whose members in the represented embodiments consist of the frame 3 , on which is pivoted a crank 52 coupled with the connecting rod 51 , which is coupled with the batten 2 , mounted on the frame 3 of the weaving machine.
  • the batten 2 in all shown and further described embodiments represents the inner member of the multimember mechanism, whose outer members are represented by the springs 210 , 220 and the crank 52 .
  • the multimember mechanism can for example be a cam or a hinge mechanism.
  • Fig. 1 and 2 is on the frame 3 of the weaving machine by a known not represented manner firmly fixed the beam 1 , on which are by one of their ends mounted the leaf springs 210 , 220 , which form deformable walls 21 , 22 of the batten 2 .
  • the leaf springs 210 , 220 On the opposite ends is between the leaf springs 210 , 220 firmly fixed the stringer 230 , which is made of a section from a light material.
  • the stringer 230 connected to the leaf springs 210 , 220 using straps and bolts, while it is necessary to maintain firm and stationary connection of the ends of the leaf springs 210 , 220 and the stringer 230 .
  • the leaf springs 210 , 220 and the stringer 230 form an open rectangular profile, which form the batten 2 and whose length corresponds in a well known manner to the width of the weaving machine.
  • On the stringer 230 of the batten 2 is fixed the reed 4 and with it corresponding accessory parts, for example auxiliary blowing jets, compressed-air line etc.
  • On the stringer 230 of the batten 2 are further fixed consoles 231 , by which is the stringer 230 coupled with the driving device 5 , which is shown only schematically and which can be represented by a not represented cam or hinge mechanism or another appropriately chosen well known type of a drive. In the represented embodiment are on the consoles 231 pivoted connecting rods 51 of the drive hinge mechanism.
  • leaf springs 210 , 220 and the stringer 230 form an open profile in the shape of a parallelogram or a general tetragon, while the springs can have different lengths and they do not have to be mounted on a common beam but each of them can have its own beam. Rectangular profile shown and described in the embodiment according to Fig. 1, 2 and others appears to be the most advantageous to reach an optimal translation motion of the reed 4 and production simplicity.
  • the stringer 230 of the batten 2 is designed with regard to its transverse and longitudinal rigidity with purpose to prevent its deformations during the reverse motion within the weaving mode, i.e. particularly its twisting and bending within the length of the stringer 230 , in particular in the direction of a beat-up.
  • it can be made of a hollow section of appropriate rigidity.
  • rigidity of the leaf springs 210 , 220 must allow their deformation providing translation, in principle horizontal movement of the stringer 230 and it must prevent at the same time deformations in vertical direction and twisting strain.
  • the leaf springs 210 , 220 In a deflected position of the batten 2 the leaf springs 210 , 220 are bent to two reversed arches, as apparent from Fig. 2 and in the balanced position they are upright, as shown in Fig. 1 .
  • a driving device 5 imparts by the action of an external deflection force a reverse movement to the stringer 230 and also consequently the reed 4 and the stringer 230 of the batten, on which the reed 4 is positioned.
  • the reverse movement of the stringer 230 and all parts fixed on it, in particular the reed 4 is realized between their beat up AA and shed positions BB , which are shown in Fig. 1 and 2 .
  • Due to deformation of the leaf springs 210 , 220 the stringer 230 with the reed 4 displays a curvilinear translation motion.
  • the leaf springs 210 , 220 can be in the upright balanced position shown in Fig. 1 or in the deflected position shown in Fig.
  • the leaf springs 210 , 220 from each of deflected positions tend to return to their balanced position shown in Fig. 1 , where they are upright. That means that the entire batten 2 tends to return to its balanced position shown in Fig. 1 and tends to stay in it.
  • an energy accumulated in the leaf springs 210 , 220 which generates restoring force acting while their reverse movement back to the balanced position.
  • the leaf springs 210 , 220 are made of steel.
  • the leaf springs can however be made of another appropriate material, for example carbon composite material or another appropriate composite material.
  • the stringer 230 can be made of a body from a carbon composite material or another appropriate composite material and the leaf springs 210 , 220 can be made of steel.
  • the number of leaf springs can be limited to two but it can also be higher. If required, it is possible to use three to four springs.
  • the batten 2 composed of a body formed of deformable walls 21 , 22 connected by a connecting wall 23, representing the stringer 230 of the batten, into an open rectangular profile.
  • the stringer 230 is as well as in previous embodiment positioned the reed 4 with accessory parts and the consoles 231 , which are coupled with the driving device 5 .
  • the deformable walls 21 , 22 of the batten are composed of the leaf springs 210 , 220 , whose ends 211 , 221 are firmly fixed on the beam 1 , which is mounted on the frame 3 of the weaving machine.
  • the batten composed of one piece of a shaped composite material, which is made of a fibrous reinforcing material in a polymer matrix.
  • the fibrous reinforcing material can advantageously be made of a system of carbon fibers or direction oriented layers of separate carbon fibers.
  • the polymer matrix is advantageously composed of an epoxy resin.
  • a hollow closed auxiliary profile 2301 which is inserted into the inner space of the batten 2 formed by an open rectangular profile and in the inner space is braced by an inner connecting wall 24 .
  • the hollow of the auxiliary profile 2301 is in the represented embodiment for increasing the rigidity of the stringer 230 of the batten filled by a filling 2302 formed by a foam material, honeycomb filler or another suitable material or it can stay empty.
  • the leaf springs 210 , 220 are again by their ends mounted on the beam 1 and therefore the function of the batten 2 during weaving is consistent with the previous example of embodiment according to Fig. 1 and 2 .
  • the batten 2 shown in Fig. 7 and 8 is composed of a hollow rectangular profile, which is composed of deformable walls 21 , 22 connected by the connecting wall 23 , while into the inner space of the hollow rectangular profile is in a certain distance from the connecting wall 23 inserted an inner connecting wall 24 , so that between the connecting wall 23 and the inner connecting wall 24 is formed a hollow space.
  • the connecting wall 23 and the inner connecting wall 24 form together with a part of the walls 21 , 22 positioned in between them the stringer 230 of the batten.

  • the leaf springs 210 , 220 due to their pivoted fixing in hinges 2101 , 2201 of the machine frame 3 bend only into one arch as shown in Fig. 8 . They are however able to take a deflected and the balanced position, while they can be deflected into any side of the batten 2 .
