Definitions
- the present invention relates to a weft insertion device for weaving machines according to the preamble of claim 1 and a method for pneumatic insertion according to the preamble of claim 4.
- the invention is therefore based on the object of improving the weft insertion device mentioned at the outset in such a way that it ensures flawless, maintenance-insensitive operation with four, six or more blowing nozzles while avoiding the disadvantages of the prior art mentioned.
- the weft insertion device characterized in claim 1. Then four, six or more blowing nozzles are arranged horizontally in close proximity in pairs in front of the U-shaped channel or another air guidance system (confuser) of the reed beam, so that pivoting or rotating the nozzle body is unnecessary.
- blowing nozzles are mounted in the front area on one or more pneumatic cylinders, which can be arranged side by side or one behind the other. They effect the actual pivoting of the nozzles by conventional control, a corresponding number of compression springs being provided on the opposite side, which act as a suspension or counterforce in order to dampen undesired vibrations or ensure the precise entry of the desired weft thread.
- Fig. 1 is a perspective schematic view of the weft insertion device according to the invention.
- the weft insertion device according to the invention for weaving machines with pivotable blowing nozzles is generally designated 10.
- the main or blowing nozzles 18 are connected to the sley 26 at their rear end via the nozzle body 13.
- the blowing nozzles 18 can be pivoted vertically around the center of gravity 36 of the nozzle body 13.
- Each of the six blowing nozzles 18 shown has its own storage or cutting device (not shown).
- the six weft threads to be entered are designated 32.
- Each of the tubular nozzles 18 has its own compressed air line 19, which are each connected to corresponding compressed air containers (not shown).
- the holder 52 which combines the blowing nozzles 18 in their front area and in turn connects them to the sley 26.
- two pneumatic cylinders 34a and 34b are arranged one behind the other and below the blowpipes 18. They are in contact with two clamps 37 which surround the blow nozzles 18 and which bundle the tubes together.
- a compression spring 35 is arranged above the clamps 37, which cooperate as a counterforce with the pneumatic cylinders 34a and 34b, since they are clamped between the clamps 37 and the holder 52.
- the number and arrangement of the pneumatic cylinders 34 and the compression spring 35 is not critical, but can be selected within a suitable framework, as long as it is ensured that a correct and precise pivoting of the tubular blowing nozzles 18 is ensured, so that the respective shot lengths 32 are obtained from the desired ones Blow nozzles 18 can enter the U-shaped channel 14 of the reed 16.
- This is shown more clearly in cross section at the bottom left in FIG. 1, where the openings 1 and 2 of the uppermost blowing nozzles 18 are in the entry position for the U-shaped channel 14 of the reed 16, while the middle openings 3 and 4 and the lower openings 5 and 6 of the blowing nozzles 18 are below the entry position and are therefore in the rest position.
- the weft insertion device according to the invention for weaving machines in the basic position shown can insert color and / or quality from the openings 1 and / or 2 of the blowing nozzles.
- the pneumatic cylinder 34a When the pneumatic cylinder 34a is actuated, the openings 3 and / or 4 of the blow nozzles 18 are brought into the firing position, while the actuation of the pneumatic cylinder 34b ensures that the openings 5 and 6 of the blow nozzles 18 are brought into the desired firing position.
- this system can be expanded to include other colors and / or qualities. It is also think bar that only one pneumatic cylinder 34 is used, the stroke of which is controlled in different ways.
