Definitions
- the invention relates to a control device for the nozzles of a jet entry weaving machine, in particular for an air entry machine with a traveling field and so-called auxiliary nozzles arranged along the entry path.
- a rotary valve rotating on a shaft and having a disc-shaped configuration is located in a pressure chamber. There is an opening in the rotating disc which runs over several outlet openings for the connection of nozzles.
- a difficulty with this embodiment is that the rotary valve slides over the base plate of the pressure vessel containing the air outlet openings, which can impair the seal between the two parts.
- more wear can occur at the more external locations of the rotary valve due to the higher radius than on the inner part of the rotary valve. This can result in uneven tightness at the outer and inner points of the rotary valve during operation.
- the uneven abrasion cannot be easily compensated for in this embodiment with a disc-shaped rotary valve during operation.
- the number of nozzles that can be connected to the pressure chamber is limited, so that the known design is not suitable for weaving machines with a large weaving width and numerous auxiliary nozzles.
- the invention has for its object to provide a control device which is particularly improved in this regard.
- the invention resides in a stationary, drum-shaped pressure vessel and a cylindrical control spool rotating therein, the pressure vessel on the circumference a plurality of staggered, preferably helically arranged outlet openings for the connection of the nozzles and the control spool extending over the entire length of the control spool, have essentially axially parallel slot.
- control device in the control device according to the invention, it can also be as follows. is easily achieved that those air outlet openings of the pressure vessel that belong to nozzles, which, for. B. to blow during the entire weft entry, are supplied with air by simple bypass channels longer than other, not intended, nozzles located on the entry path.
- a control drum designated as a whole with 2 is attached on the frame 1 of an air intake weaving machine, not shown. It consists of a cylinder 3 and two, on the front, placed on this, essentially disc-shaped cover 4, 5.
- a hollow shaft 8 is mounted with the interposition of ball bearings 6 and a seal 7. At the left end in FIG. 1, this carries a toothed pulley 9, over which a toothed belt 11 is placed. From it, the hollow shaft 8 is driven synchronously with the main shaft of the loom according to arrow 12 during operation.
- a cylindrical, rotating control slide 14 is driven by the hollow shaft 8 by means of two pins 13 and has a slot 15 running parallel to the axis.
- the pins 13 fastened in the hollow shaft protrude in the middle 30 of the z. B. over about 280 ° circumferential sector of the rotary valve 14 in this bore 81 with little play, which are located opposite the center 82 of the axial slot 15.
- the rotary slide valve 14 is coupled to the hollow shaft 8 for rotation.
- the cylinder 3 has bores 16, to which air lines 17 for several nozzles of the weaving machine are connected. These so-called auxiliary nozzles are attached along the entry path for the weft thread. Through them, the thread tip is carried further in the direction of the entry path.
- compressed air is introduced into the hollow shaft 8 according to arrow 18. It passes through bores 22 in the shaft 8 into the space 19. Due to the air in the pressure space 19, the rotary slide valve 14 is constantly pressed against the inner circumference 41 of the cylinder 3 with a slight expansion, so that it runs in a sealing and sliding manner thereon.
- the overflow slot 15 of the control slide 14 runs successively via the helical air outlet bores 16 in the cylinder 3, so that the lines 17 are successively fed with air.
- the cylinder 3 contains, on the circle of its inner circumference on which the right-hand bore 16 in FIG. 1 lies, further bores 16a to 16e, into which additional bores 5, 25a to 25e, which run parallel to the hollow shaft 8, open out.
- the lid 5 also contains a z. B. over about 160 ° extending bypass channel 26, which is placed against a part of the channels 25, 25a to 25e. By rotating the cover 5, the bypass channel 26 can be placed over a selectable number of bores 25, 25a to 25e and thus adjusted. 3, the bypass channel 26 is opposite the channels 25, 25a to 25c, so that these channels are connected to one another by the bypass channel 26.
- FIGS. 1 to 4 For the operation according to the diagram according to FIG. 5, it is assumed that six control drums according to FIGS. 1 to 4 are arranged along the weaving width of the weaving machine designated by B and plotted on the abscissa of FIG. 5.
- the six control drums are labeled 31 to 36.
- the first four nozzles connected to the air supply lines 17 receive air from the opening time 37 or 37a to 37c to the closing time 38 or 38a to 38c, so that they blow in the period designated 39 for all four nozzles of the same length.
- the connecting line 17 on the right in FIGS. 1 and 2 and the associated nozzle receive air from their opening time 37d to the closing time 38d, which is at the end of the entry duration or the rotation angle A of the main shaft of the weaving machine.
- a rotary control slide 14 is used, which already bears on the inner running surface 41 of the cylinder 3 when the parts are assembled under prestress.
- the control slide 14 can, for. B. consist of a plastic so that the parts can run on each other without lubrication. This also means that the air, auxiliary nozzles, weft threads and fabrics remain free of lubricants.
- the number of control devices used over the weaving width B can of course also be more than six.
- Each individual control drum can also have more than five connecting lines for five associated nozzles.
- a control drum according to FIGS. 1 to 4 can also be used to control a so-called main entry nozzle arranged on the weft side of the weaving machine outside the shed.
- the slot 15 of the rotary slide valve 14 does not need to run completely parallel to the shaft 8, it can, for example, also be of helical design. It can run in the sense of the screw shape of the arrangement of the bores 16, but with a different inclination or in an opposite screw direction.
- the width of the slot 15 can also be designed differently.
