Definitions
- the invention relates to a device for guiding at least one rapier rod on a rapier weaving machine with at least two guide aids spaced apart in the longitudinal direction of the rapier rods in the region of a rapier rod drive.
- Such gripper bars usually have a toothed long side, in which a drive gear, preferably with a vertical axis, engages, as described in Belgian Patent No. 868946.
- a pair of gearwheels mounted on a vertical drive shaft can then be provided for simultaneously driving both gripper rods.
- the at least one gripper bar must be supported next to the fabric edge and be guided by a guide device so that it follows the desired path during its back and forth movement.
- These guide aids can include first guide aids on the fabric side of the gripper bar drive, preferably in the form of guide plates, furthermore second guide aids in the area of the gripper bar drive element, in particular drive gear, these second guide aids preferably being in the form of rollers, and finally third guide aids on the side facing away from the fabric the gripper bar drive, preferably in the form of a straight guide provided with a guide profile.
- these at least two guide aids have been arranged separately on the frame of the weaving machine.
- the consequence of this is that for the precise setting of the movement path, in particular for setting the takeover location in the middle of the subject in the case of use of donor and slave grippers, at which location the sensor and slave grippers meet and the weft thread is used is taken, these guide aids must be set separately in order to impress each gripper on the desired direction of movement. This requires long response times.
- the object of the invention is to shorten this response time considerably.
- the guide aids are arranged on a common carrier adjustable relative to each other, and that the carrier is arranged adjustable on the frame of the loom.
- the common carrier has to be adjusted accordingly on the frame of the weaving machine for gripper bar adjustment. If more than one gripper bar is used on one side of the fabric, the gain in setting time achieved by the invention is correspondingly higher, since in turn only the carrier common to all gripper bars has to be adjusted.
- the basic setting of the gripper bars on the common carrier usually remains independent of the usual setting changes, e.g. Adjustment to the width of the fabric.
- the carrier be rotatable about an axis which coincides with the axis of rotation of the drive gear. This measure ensures that reliable, low-wear gripper bar drive is guaranteed even after changing the setting of the common carrier.
- the carrier comprises a gripper guide housing.
- the mentioned guide aids can be attached, which are both an exact gripper bar guide and one allow exact gripper bar adjustment relative to the carrier. This adjustment is generally only to be made for the basic setting of the rapier weaving machine and, if necessary, to take account of signs of wear, whereas the carrier adjustments are to be carried out much more frequently, in particular when changes in fabric parameters, such as fabric width, for example.
- the first guide aids preferably in the form of guide plates, can be adjusted independently of one another in three directions relative to the carrier, each with the warp direction, the weft direction and the height match.
- the second guide aids preferably in the form of rollers, be adjustable relative to the carrier in a direction perpendicular to the longitudinal direction of the gripper rods.
- the third guide aids preferably in the form of a straight guide provided with a guide profile, can be adjusted in height relative to the carrier while maintaining their orientation.
- the carrier in particular the gripper guide housing, is attached to a hub which can be rotated about the vertical axis of rotation of the drive gearwheels and can optionally be fixed in different rotational positions relative to the frame of the weaving machine.
- the guide aids means and the support unit formed can be fixed at least at a second location relative to the frame.
- This measure also helps to reduce any vibrations in the arrangement.
- first guide aids are designed to be adjustable parallel to the longitudinal direction of the gripper rods to adapt to the respective fabric width.
- the first guide aids can be arranged to be adjustable along the rail; additionally or alternatively, it is possible to arrange the rail with adjustable length relative to the carrier, in particular gripper guide housing.
- the carrier comprises a rail which runs parallel to the longitudinal direction of the gripper rods and which connects the first guide aids to the gripper guide housing.
- the rapiers 1 (FIG. 1) sit on the outer ends of the rapier bars 2, each of which is driven by a drive gear 3 lying in a horizontal surface, via a vertical shaft 4 a movement is granted.
- Those gripper bars 2 must be supported and guided at various points so that they move in the right direction during their back-and-forth movement and the gripper and receiver grippers meet for the transfer of the weft threads in their take-over position.
- two gripper bars 2 are shown with a common guide unit.
- each gripper bar is guided by three machine parts (guide aids).
- the head of the gripper bar is supported by a guide plate 5, the rear end of the gripper bar is surrounded by a profiled straight guide 6, and opposite the drive gear 3, several rollers 7 are provided, which guide the back of the gripper bars 2 and these at the correct distance from let the vertical shaft 4 pass so that they interact with the drive gears 3 seated on that shaft 4.
- the three machine parts are adjustably connected to one another as a unit, and this is connected to one or more parts fixedly arranged on the frame of the weaving machine.
- a gripper guide housing 8 is provided. That gripper guide housing 8 is attached to a hub 9, which is rotatably arranged around the shaft 4 of the drive gearwheels in the gear housing 10 of the gripper drive (FIG 2).
- the gripper guide housing 8 also has a plurality of elongated holes 11, in which there are screw bolts 12 which can be tightened in the motor housing 10 so that it can be fixed in the desired direction.
- the gripper guide housing 8 preferably has the shape of a half cylinder, which stands upright around the drive gears 3 to protect them.
- the various guide aids are adjustably attached to that gripper guide housing 8 (FIG. 1).
- the rollers 7 are seated in a frame 13 which can be set perpendicular to the gripper rods and can be fixed on the gripper guide housing 8 by means not shown.
- the straight guides 6 are accommodated in a height-adjustable manner in a U-profile 14, which is fixedly attached to the gripper guide housing 8 with respect to the gripper guide housing 8.
- the guide plates 5 are suspended from a rail 16 via an adjustable support structure 15 (FIG. 3).
- the support structure 15 is adjustable relative to the gripper guide housing 8 in the direction of the gripper bars 2 so that the position of the guide plate 5 can be adapted to the fabric width.
- the support structure 15 of the guide plate 5 is chosen such that it can be adjusted in three directions and each of the three directions can be changed independently of the others; the directions correspond to the warp direction, the height and the weft direction.
- the guide plates 5 (FIG. 3) are each suspended on one leg of a horizontally lying bracket 17 and can be adjusted in the warp direction with set screws 18.
- the two brackets 17 are each suspended with a bolt (for example screw bolt) in a vertical slot 22 in a support piece 19 so that their height position can be adjusted.
- the support piece 19 is in a horizonta with the aid of a bolt (eg screw bolt) 24 len slot 23 of the rail 16 fixed so that the guide plate 5 are to be moved and adjusted in the weft direction.
- the U-profile 14 of the straight guide 6 is provided with a support 20 which is to be fixed with a screw bolt in a horizontal elongated hole on part of the frame.
- the device according to the invention allows the gripper bar guide aids to be adjusted in an effective and progressive manner. After the direction of the rapier rods 2 is first determined, the other guide aids can be set independently of one another in accordance with the requirements of the weaving machine and the weaving process. It goes without saying that the present invention can be applied to both double-piece and single-piece weaving machines.
- Device for guiding the rapier rods on a rapier weaving machine in which the drive gears 3 of the rapier rods 2 lie in a substantially horizontal surface, consisting of a plurality of guide aids 5, 6, 7, which are provided on one of the two sides of and / or opposite the drive sprockets 3 are characterized in that the mutually adjustable guide aids 5, 6, 7 are assembled into a single unit, which is adjustable on the weaving machine, preferably rotatable about an axis that coincides with the axis of rotation of the drive gears 3.
