Definitions
- the invention relates to a weaving machine consisting of a mechanism for reverse run of a reed composed of a multimember mechanism with a lowered reduced moment of inertia and coupled with a drive.
- the well known weaving machines consist of a system of members, which provide the reverse run of a reed, which is in known weaving machines realized by a reverse rotation movement due to positioning the reed on a swivel batten, which is a member of a multimember mechanism driven by a motor.
- the batten of the weaving machine is composed of a swivel 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 swivel tube pivoted in the frame of a weaving machine and coupled with a driving device, while the batten represents the outer member of the multimember mechanism.
- On the swivel tube are firmly fixed slay swords, on which is fixed a carrier of the reed.
- the drawback of this solution is the load distribution in 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 the batten and the reed is minimal.
- the solution is based on that the motor rotation course data are collected and in pre-determined moments is the motor controlled so that in defined constant rotating speed it reached another desired default torque.
- Such control is in a machine, in particular in a weaving machine difficult and employs a motor with a high input and above all it does not enable a control within one revolution of the machine, i.e. during one revolution of the machine drive shaft, which is for the weaving machine disadvantageous.
- the goal of the invention is to eliminate or at least to minimize the drawbacks of the art and to improve parameters of a weaving machine.
- a weaving machine whose principle consists in that the drive of the mechanism for reverse run of a reed consists of a motor with controUably variable spin velocity within each revolution, where it is coupled with a control device.
- Such weaving machine enables easily and quickly to optimize a lifting function of regulated mechanisms, in particular a lifting function of the multimember mechanism for reverse run of the reed.
- this type of motor is also enabled to substantially simplify the multimember mechanism for reverse run of the reed.
- this mechanism for reverse run of the reed consists of one of inner members composed of a stringer of a batten.
- the invention is described on an example of embodiment of a leno fabric weaving machine consisting of well known parts, which are not further described and are marked only schematically.
- the weaving machine consists of a multimember mechanism for reverse run of a reed i, which is in an appropriate manner mounted on a batten 2, which is mounted on a beam 3.
- the beam 3 ⁇ or a part of the batten 2 corresponding to the beam are mounted on a frame 4 of the weaving machine, which is described only schematically.
- the reed 1 is positioned on a stringer 20 of the batten 2.
- the stringer 20 of the batten 2 is coupled with a connecting rod 50, which is coupled with a crank 52 coupled with a drive.
- the stringer 20 of the batten 2 is the inner member of the multimember mechanism for reverse run of the reed 1.
- the crank 52 and deformable walls 21, 22 of the batten 2 composed of leaf springs 210, 220 represent outer members of the multimember mechanism for reverse run of the reed 1.
- the multimember mechanism for reverse run of the reed 1 consists of a cam mechanism.
- the multimember mechanism for reverse run of the reed i consists of a suitably arranged hinge mechanism, where the stringer 20 of the batten 2 represent the inner member and the crank 52 and walls 21 , 22 of the batten 2 represent the outer members.
- the multimember mechanism for reverse run of the reed ⁇ with a lowered reduced moment of inertia is coupled with a motor 6 with controUably variable spin velocity within each revolution, i.e. it is coupled with so-called electronic cam.
- the motor 6 with controUably variable spin velocity within each revolution is coupled with appropriate not represented control device.
- the multimember mechanism for reverse run of the reed 1 with a lowered reduced moment of inertia enables the use of the motor 6 with controUably variable spin velocity within each revolution because this mechanism requires for its good function drive by a motor with distinctively lower power than the drive in contemporary weaving machines, where the use of electronic cams is impossible because motors 6 with controUably variable spin velocity within each revolution with a requirement of high power consume a high part of delivered power only for its own function and are no more able with a controUably variable spin velocity within each revolution to drive so far known multimember mechanisms providing reverse run of the reed A.
- the motor 6 with controUably variable spin velocity within each revolution coupled also a part of a shed device of the weaving machine, which is enabled by use of a multimember mechanism providing reverse run of the reed ⁇ _ with a lowered reduced moment of inertia.
- the action of the motor 6 with controUably variable spin velocity within each revolution is synchronized With the action of other parts of the weaving machine, so that faultless weaving was insured, for example the motor 6 with controUably variable spin velocity within each revolution is coupled with the control device of the weaving machine or with a control device coupled with the control device of the weaving machine.
- the weaving machine works in the manner that the motor 6 with controUably variable spin velocity within each revolution drives the multimember mechanism for reverse run of the reed 1 with a lowered reduced moment of inertia, while the course of a spin velocity within each revolution of the motor is controlled, i.e. within each cycle of the weaving machine, by which is reached an optimal lifting function of a multimember mechanism without a complex optimization by mechanical devices, for example by adjustment of parts of mechanism etc. and all that with sufficient energy for run of the multimember mechanism.
- multimember mechanism for reverse run of the reed with a lowered reduced moment of inertia are further described possible solutions for a batten 2 of the weaving machine leading to sufficiently lower the moment of inertia of the entire mechanism and consequently leading to the possibility to use an electronic cam for mechanism drive.
- the stringer of the batten composed of a light material section, while it can be connected with leaf springs using straps and bolts, while it is necessary to keep tight and stationary connection of the ends of the leaf springs and the stringer.
- the leaf springs and the stringer form an open rectangle section representing the batten and where its length corresponds in a well known manner to the weaving width of the weaving machine.
- the stringer of the batten On the stringer of the batten is fixed the reed and with it corresponding accessory parts, for example auxiliary blowing jets, compressed- air line etc.
- the stringer of the batten On the stringer of the batten are further fixed consoles, by which the stringer is coupled with a driving device, for example with a hinge or a cam mechanism or another appropriately chosen transmission type.
- a driving device for example with a hinge or a cam mechanism or another appropriately chosen transmission type.
- the consoles can for example be pivoted connecting rods of driving hinge mechanism.
- the leaf springs and the stringer 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 can have its own beam. Rectangular profile appears to be the most advantageous to reach an optimal translation motion of the reed and production simplicity.
- the stringer of the batten 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, 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 must allow their deformation providing translation, in principle horizontal movement of the stringer and it must prevent at the same time deformations in vertical direction and twisting strain. In the position of batten deflection the leaf springs are bent into two reversed arches.
- a driving device imparts a reverse movement to the stringer and consequently to the reed by the action of external deflection force.
- the reverse movement of the stringer and all parts fixed on it, in particular the reed is realized between their beat up and shed positions.
- Due to deformation of the leaf springs the stringer with the reed displays curvilinear translation motion. Nevertheless the leaf springs can be found in an upright balanced position or in a deflected position or a position deflected towards the other side.
- the leaf springs from each of deflected positions tend to return to their balanced position, where they are upright. That means that the entire batten tends to return to its balanced position and doing so it subsequently tends to hold it.
- In the batten deflected position is an energy accumulated in the leaf springs, which generates restoring force acting while their reverse movement back to the balanced position.
- the leaf springs 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 can be made of a body from a carbon composite material or another appropriate composite material and the leaf springs 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 is composed of a body formed of deformable walls connected by a connecting wall, representing the stringer of the batten, into an open rectangular section.
- a connecting wall representing the stringer of the batten
- Deformable walls of the batten are composed of the leaf springs, whose ends are firmly fixed on the beam, which is settled on the frame 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 directed layers of separate carbon fibers.
- the polymer matrix is advantageously composed of an epoxy resin.
- the leaf springs are settled on the beam and therefore the function of the batten during weaving is consistent with the previous example of embodiment.
- the batten differs from the previous embodiment only in forming the stringer of the batten, which is here formed by an auxiliary tubular hollow section, which is inserted into the inner space of the batten composed of a hollow rectangular section and in the inner space it is fixed by the inner connecting wall.
- auxiliary tubular hollow section which is inserted into the inner space of the batten composed of a hollow rectangular section and in the inner space it is fixed by the inner connecting wall.
- To increase the rigidity of the auxiliary section is its hollow in the represented embodiment filled with a filling from a foam material, honeycomb filler or another suitable material or it can stay empty.
- the leaf springs are again by their ends settled on the beam and the function of the batten during weaving is consistent with the previous example of embodiment.
- the batten is according to another not represented example of embodiment composed of a hollow rectangular section, which is composed of deformable walls connected by the connecting wall, while into the inner space of the hollow rectangular section is in a certain distance from the connecting wall inserted an inner connecting wall, so that between the connecting wall and the inner connecting wall is formed a hollow space.
- the connecting wall and the inner connecting wall form together with a part of walls positioned in between them the stringer of the batten.
- the rest of deformable walls form the leaf springs, which are in this embodiment on the other hand positioned on the frame of the weaving machine using hinges.
- the stringer of the batten fitted with consoles coupled with a driving device.
- the hollow space between the connecting wall and the inner connecting wall can be for increase of rigidity of the stringer filled for example with a foam material which is not represented.
- the leaf springs due to their pivoted fixing in hinges of the machine frame bend only into one arch. They are however able to take a deflected and the balanced position, while they can be deflected into any side of the batten. In the batten deflected position is an energy accumulated in the leaf springs, which generates restoring force acting while their reverse movement back to the balanced position.
- the batten composed of a stringer, which is using hinges fixed on the side non- deformable walls of the batten, which are hinged on the machine frame.
- the stringer of the batten is coupled with a driving device, which is a part of the multimember mechanism, where the stringer of the batten is an internal member.
- the multimember mechanism can for example be a cam or a hinge mechanism.
- the reed and the stringer of the batten displays a translation motion.
- the batten composed of a hollow rectangular section, which consists of two deformable walls connected on their ends with a connection wall and a closing connecting wall, where the connecting wall forming the stringer is strengthened and the closing wall is firmly fixed on the beam, which is settled on the frame of the weaving machine or it represents its part.
- the deformable walls are formed of the leaf springs and the function of the batten is consistent with the embodiment with the leaf springs, where their ends are settled on the beam or directly on the frame of the machine.
- the leaf springs with the stringer of the batten form one complex in the shape of an open rectangular section.
- the leaf springs are fabricated recesses, where some serve as passage of appropriate parts of the weaving machine, for example connecting rods of a driving device.
- the leaf springs are firmly fixed on the beam using straps and bolts.
- the reed is on the stringer fixed using holders.
- the beam is an integral part of the weaving machine frame or it is settled in it.
- the above mentioned embodiments serve only as examples and it is possible combine them mutually to reach the particular technical solution.
- the batten can be made of different materials of various properties, thus today it seems to be the most advantageous a composite material consisting a fibrous reinforcing material in a polymer matrix, in particular carbon fibers in an epoxy resin. In this embodiment it is easy to reach a desired different rigidity of the stringer and the leaf springs of the batten during production.
- the number of the leaf springs can be selected according to the technological and construction needs.
