Definitions

  • the invention relates to a device for shielding against flight in the inlet area of the weft thread of a weaving machine.
  • the infeed area of the weft thread or the weft threads in multi-color weaving machines extends from the weft yarn bobbins via possibly arranged intermediate stores for the weft threads and the weft insertion means, e.g. a projectile or an air jet until it enters the shed formed by the warp threads.
  • Numerous devices for cleaning the infeed area of weft threads in weaving machines have therefore been developed with the aim of removing the flight that has accumulated on machine parts or of preventing flight from accumulating at all. It is e.g. blow-off and / or suction devices, which are either attached to individual weaving machines or move individually back and forth over groups of weaving machines.
  • Devices equipped with swivel nozzles are known, for example, from DE-PS 15 35 894, DE-OS 19 19 229 or from US Pat. No. 2,798,825. It is also common to prevent air currents in the insertion direction of the weft thread and thus the further transport of flight in the direction of the shed with screens or plates which have openings for the passage of the weft thread or the weft insertion means.
  • the object of this invention is to provide a device that is as simple and effective as possible for preventing flight accumulation and the further transport of flight pads in the infeed area of the weft thread of weaving machines create.
  • the invention characterized in the claims solves the problem in that a device for shielding against flight is arranged in the infeed area of the weft thread with at least one shielding plate with a passage opening for the weft insertion means and weft thread, characterized in that at least one shielding plate is assigned a cleaning element and at least one of the mutually associated parts is movable relative to the other.
  • the advantages of the invention compared to the prior art can be seen in the fact that the flight which is also transported is stripped off after striking the shielding plate by the aforementioned relative movement to the cleaning element and is therefore not entered into the shed.
  • the flight can thus fall into the interior of the weaving machine without additional complex measures, such as blow-off devices, from where it can, for example, be suctioned off the weaving chain together with the flight.
  • blow-off devices With the highest demands on fabric quality, it is possible to operate ventilation systems to keep the infeed area of the weft thread clean with reduced air pressure and therefore low energy consumption.
  • the dimensions of the device according to the invention can be kept smaller compared to known devices, which means that fewer handicaps occur for the staff when maintaining a weaving machine.
  • the invention can be used particularly advantageously, for example, on projectile looms. Because at least part of the shield is moved in a preferred embodiment, the passage opening can be reduced in size in a simple manner after the projectile has passed through the shield, so that the weft thread can still pass through unhindered, but no flight cushions in the vicinity of the Find the way through the opening.
  • the weft bobbin 1, the weft 2 and, as a weft insertion means, the projectile 3 of a projectile weaving machine can be seen from left to right, which is caused by the reciprocating acceleration lever 4
  • the acceleration lever 4 is driven by an acceleration mechanism, which is not described in detail and which is accommodated in the transmission housing 5.
  • the housing 5 is seated on the center support 6 of the weaving machine, which also carries the cam mechanism (not shown) for the shop profile 7.
  • the reed 8 for attaching the weft thread 2 and the guide teeth 9 for the projectile 3 are mounted on the shop profile 7.
  • To the left of the reed 8 is a vertically displaceable scissors 15 for cutting off the weft thread 2 after the entry.
  • Fig. 2 the shutter profile 7 and attached to it the reed 8 and a guide tooth 9 in the two positions A and B are shown in a view in the weft direction.
  • position A the projectile 3 is inserted with the weft thread 2 according to FIG. 1 through the guide teeth 9 into the shed; the weft thread is then struck in position B on the fabric edge G in a known manner.
  • the guide tooth 9 is because of the position of the center of rotation of the shop profile in a position below the fabric edge.
  • the warp threads are in position A of the shop profile in the planes O and U perpendicular to the plane of the drawing and in position B in the plane M.
  • the space between the planes O and U is called the shed W.
  • the shielding device 11 attached to the shop profile 7 can also be seen in a preferred embodiment.
  • the shielding plate 11 is screwed with its lower right part onto the shop profile 7 similarly to the guide teeth and is passed through the reed 8 in its left raised part.
  • the height of the left part of the shielding plate 11 is chosen so that the warp threads lie within the outline of the shielding plate in any position.
  • the warp threads lying laterally behind the shielding plate 11 touch the surface of the plate and keep it clean of flight deposits.
  • In the right part of the shielding plate 11 there is an opening 18 at the level of the recess in the guide teeth 9, which allows the projectile and the weft thread attached to it to pass through. From this opening, a slot runs to the left towards reed 8, which releases the weft thread towards the reed 8 during the stop against the fabric edge G.
  • the shielding plate 11 is shown in position B in its position relative to the fabric spreader 12.
  • the plate 14 is fastened on the spreader cover 13 at a small lateral distance from the shielding plate 11 as a cleaning element.
  • the plate 14 has the task of scraping away flight deposits on the shielding plate 11 just in the area of the passage opening. It should also be mentioned that the shielding plate 11 according to FIG. 1 is fastened as far to the left as possible on the shop profile 7, so that flight accumulations cannot reach the area of the reed 8.
  • FIG. 3 Another advantageous embodiment of a moving shielding device against flight is shown in FIG. 3 in three positions.
  • the shielding plates 16 and 17 are arranged at the top with a small lateral distance from one another in the weft direction.
  • the scissors 15 are in their lowermost position on the left in FIG. 3, so that the axis of the weft thread 2 is centered in that through the two plates 16 and 17 formed opening 18 ', which also allows enough space for the passage of the projectile 3.
  • the scissors are moved upwards in the open state, so that only the narrow gap formed by the edges 19 and 20 of the plates 16 and 17 is free for the passage of the weft thread.
  • This phase can be seen in the middle representation in FIG. 3.
  • the scissors 15 go into the uppermost position and cut through the weft thread in the position in FIG. 3 on the right, the shielding plates 16 and 17 overlapping one another and thereby being able to strip away flight deposits on the surfaces facing one another.
  • other stationary parts not shown, similar to the plate 14 in FIG. 3 or brushes on the left and right of the plates 16 and 17 can be attached.
  • the shielding plates 16 and 17, which can be moved against one another and against fixed scraper parts and which have only a small mass, can easily be attached to other moving elements in the weft insertion area.
  • the moving plate twice congruently with a small space so that the opposite fixed plate comes into the space between the two arranged plates during the relative movement, whereby the fixed plate from is cleaned on both sides.
  • the arrangement of the device according to the invention can be seen in a spatial representation in the two variants described in FIGS. 4 and 5.
  • FIG. 5 shows the other described embodiment of a shielding device, in which the shielding plates 16 and 17 according to FIG.
  • FIG. 6 a view of the weft channel in the shed and the shielding device 11 in front of it can again be seen, analogously to FIG. 2.
  • it carries the elongated, rotatably mounted plate 23, with which the opening 18 in the shielding plate 11 can be almost completely covered. It acts as a cleaning element and shielding plate at the same time.
  • the plate 23 is pulled by the spring 24 to the eccentrically mounted stop 25, unless the plunger 27 of the magnet 26 presses upwards on the plate 23, as a result of which its right part swivels downward and widens the passage opening 18 in the shielding plate 11.
  • the magnet 26 is attached to the cross member 28 of the weaving machine frame. Positions A and B correspond to those in FIG. 2.
  • Fig. 7 the plate 23 in Fig. 6 is replaced by the vertically moved plate 29, which is driven by the plunger 30 and the roller 31 by the cam 32, which sits on the main shaft of the weaving machine.
  • the plates 23 and 29 from FIGS. 6 and 7 are moved upwards after the weft insertion means has passed and still during the weft insertion. They are in the down position for the rest of a weaving machine cycle.
  • the shielding plates 16 and 17 mutually effect the plates 23 and 29 in their interaction with the shielding plate 11 in addition to the reduction of the passage opening 18, the cleaning of the surfaces facing one another.
