Definitions
- the invention relates to a rapier weaving machine according to the preamble of claim 1.
- Rapier looms of the type mentioned are known several times.
- EP-PS 0 126 497 describes such a rapier weaving machine in which the entry belt engages with the drive wheel over part of the circumference, a block-shaped guide member holding the entry belt on the circumference of the drive wheel both at the beginning and at the end of the engagement .
- the end of the belt facing away from the gripper head is guided in a guide channel. It is very disadvantageous that the block-shaped guide elements are exposed to a great deal of heating and great wear due to the friction, which has a disadvantageous effect on the working accuracy and the service life.
- Rapier weaving machines are also known which work with non-perforated entry belts.
- a rapier weaving machine is known from CH-PS 652 764, in which the end of the belt facing away from the rapier head is firmly connected to a drive wheel, an entry belt being used which is not perforated, so that the force is introduced via the end of the belt and the belt one or more layers can be wound on the driving wheel.
- a complicated guiding device which contains a rope, the two ends of which are fastened to the drive wheel, and this several times the drive wheel is looped and is additionally guided over rollers which are arranged outside the drive wheel. These rollers serve on the one hand for tensioning the rope and on the other hand for deflecting the rope from a guide area on the circumference of the drive wheel to the top of the entry belt wound on the drive wheel.
- This guiding device is extremely complicated and requires additional driving forces in order to hold the entry belt on the driving wheel and because of the convoluted guiding and deflection of the rope.
- the object of the invention is to design a rapier weaving machine of the type mentioned at the outset in such a way that an increase in speed, for example to 1000 rpm, is possible, and yet simple guiding of the entry belt is ensured, which is subject to only slight wear and requires only low driving forces and which Absorbs centrifugal forces.
- the object is achieved according to the invention by the characterizing features of claim 1.
- the fact that the entry belt is perforated and driven in the circumferential direction by a toothed drive wheel, so that the introduction of force is practically given or received in the direction of movement of the gripper head and that the end of the belt facing away from the gripper head is fastened to a rotatable guide device means that the guide channels are not required Frictional forces, which not only benefits the protection of the entry belt, but also prevents the entry belt from lifting off the circumference of the drive wheel. This is particularly the case when, for example, the guide device is coupled to the drive wheel in terms of drive, so that the drive wheel does not have to exert any tensile or compressive forces for the section of the entry belt which faces away from the gripper head.
- the drive and the guidance of the entry belt is extremely low in friction, because the driving force and the centrifugal force due to the extent Directional engagement of the input belt and drive wheel and is taken up by the fastened end of the input belt with the rotating guiding device, whereby no wear occurs, which has an extremely favorable effect on the accuracy and long service life of the rapier weaving machine.
- the low friction forces reduce the driving forces required. A reduction in the driving forces is also promoted by only small moving masses. Ultimately, this all means that much higher speeds of up to 1000 rpm are possible, and practically without wear, which is synonymous with low-noise operation, increased lifespan of the rapier weaving machine and low vibrations.
- the guide device for the belt end of the input belt facing away from the gripper head can be an additional guide wheel according to claim 2. This can either be driven by the moving input belt, but the guide wheel is preferably coupled to the drive wheel in terms of drive. The inertia forces can be further reduced if the guide device is designed according to claim 3.
- An embodiment of the rapier weaving machine according to claim 4 is particularly advantageous since the drive wheel and thus the moving inertial forces can then be kept small.
- the guide device is arranged independently of the driving wheel, a further guide element is recommended.
- An embodiment of the rapier weaving machine according to claim 7 is particularly advantageous, since then a guide device that is independent of the driving wheel is not necessary.
- an embodiment according to claim 8 is advantageous.
- the guide member which is assigned to the drive wheel on the side of the gripper head, can be designed as a sliding guide according to claim 9.
- an embodiment according to claim 10 is more advantageous, as a result of which the friction between the input belt and the guide wheel is eliminated.
- An improvement in the drive between the guide wheel and the entry belt can be achieved by driving coupling of the guide wheel to the drive wheel, the guide wheel then also being able to serve to support the drive.
- These properties are further improved by an embodiment of the guide wheel according to claim 11.
- the guide wheel can interact with the perforation of the entry belt, which is intended for engagement with the drive wheel.
- an embodiment according to claim 12 is more advantageous since there is then a more subtle interaction between the guide wheel and the entry belt.
- the management properties of the management body can be improved by an embodiment according to claim 13 and / or 14.
- the rapier weaving machine can be equipped with a single weft insertion device which is effective from one side of the shed through the entire shed.
- the gripper heads can cover the same length of travel according to claim 16, or different paths according to claim 17. It is also possible that the rapier heads are inserted into the shed from both sides synchronously or out of phase. It is even possible that the rapier head that draws the weft thread into the shed is already in the retraction movement when the other rapier head takes over the weft thread. According to claim 18, it is also possible to insert a weft thread from each side of the shed, which are preferably connected to one another according to claim 19.
- the compressed air can simultaneously press the entry belt against a drive wheel, thereby counteracting the centrifugal force of the driven entry belt and thus ensuring that the entry belt is held securely on the drive wheel.
- the sliding guide can be limited to the area facing the gripper head, at which the entry belt leaves the driving wheel.
- An embodiment according to claim 22 is also advantageous, as a result of which a secure hold of the entry belt on the drive wheel is ensured. Since a friction-reducing air cushion is formed by the compressed air, such a guide element can advantageously be arranged along the entire area on which the entry belt rests on the drive wheel. This ensures a secure hold of the entry belt on the drive wheel, the compressed air preferably being able to be set such that the entry belt is in contact with the drive wheel despite the centrifugal force.
- the entry belt can be a smooth, continuous belt, but a perforated entry belt is advantageous, in which case an embodiment according to claim 24 is particularly advantageous and ensures that the entry belt rests securely on the drive wheel.
- An embodiment according to claim 25 is also particularly advantageous, as a result of which the guidance of the rapier head and the entry belt on the reed is improved.
- an embodiment according to claim 26 is advantageous.
- An embodiment according to claim 27 is also particularly expedient, since the compressed air supply at the individual consumer points can then be adjusted according to individual needs.
