Definitions
- the invention relates to a weaving machine with means for forming weaving sheds with an upper chain and with a lower chain and with a machine frame with at least one cross strut.
- weaving dust arises from the mutual friction of the warp threads moving up and down as well as from the friction of the warp threads with lamellae of warp thread monitoring devices and strands of loom frames.
- the warp beam can already contain weaving dust that was released during the production of the warp beam.
- weaving dust can come from neighboring weaving machines.
- weaving dust will accumulate and deposit on cross members connecting side parts of a machine frame, which are designed as profile supports. Accumulated weaving dust can get into the area of the warp threads as dust balls or dust accumulations and cause warp thread breaks, especially in the area of the weaving frames or shafts. It is known (US Pat. No. 5,074,337) to blow the weaving dust by means of cross brace blowers. As a result, however, the blown-off weave dust can also get into the area of the warp threads and give rise to warp thread breaks.
- the invention has for its object to avoid dust accumulation, especially in the area of cross struts.
- the at least one cross strut is covered with a shield, the upper side of which is arranged directly below the lower chain.
- Such a shield protects the cross strut against deposits of weaving dust. No weaving dust can be deposited on the shield itself, since it is carried along by the warp threads of the lower warp that run close to it. This weaving dust is then taken along in the running direction of the warp threads and falls down into an area of the machine from which it can be extracted in a known manner.
- 1 shows a schematic representation of a weaving machine with a shield according to the invention
- 2 shows a section through a shield according to the invention on a larger scale
- Fig. 3 is a longitudinal section along the line III-III of Fig. 2 and
- Fig. 4 shows a further embodiment of a shield according to the invention.
- the weaving machine shown in FIG. 1 contains a machine frame with two side parts (1) in which a warp beam (2) with its axis (3) is mounted.
- a height-adjustable support part (4) is attached to each side part (1) and supports a match tree (5) by means of a support device (6).
- a holder (7) is arranged on each of these support parts (4), to which a warp thread monitor device (8) is attached.
- the loom also has looms (9) which are guided by means of guide means (10) attached to the side parts and can be moved up and down by means of drive means (11).
- the weaving machine also contains a weaving drawer (12) with a weaving reed (13), a fabric support (14), a breast beam (15) and a fabric winding system (16).
- a dust collecting cloth (17) Arranged above the warp beam (2) is a dust collecting cloth (17) which extends from the area of the warp thread monitor device (8) approximately following the contour of the warp beam to the area of the center of the machine in which a suction device (not shown) is attached is arranged. The weaving dust falling onto the dust collecting cloth (17) is thus discharged downwards.
- a cross strut (18) is arranged between the weaving frame (9) and the warp thread guard device (8), which is designed as a profile and connects the two side parts (1) of the weaving machine.
- the looms (9) open looms (22) one after the other between the fabric edge (19) of the fabric (20) and a loom shed support (8A) arranged on the warp guard device for the insertion of weft threads.
- the shed compartments are delimited in the end positions by a lower chain (23) and an upper chain (24).
- the cross profile (18) is located in the vicinity of the warp threads (21) on the underside of the lower chain (23) which faces the warp beam (2) and / or the warp thread monitor device (8). In the example shown, this side of the lower chain (23) is located in a so-called rear compartment, ie between the loom frame (9) and the loom compartment support (8A) of the warp thread monitor device (8).
- the cross strut (18) is protected by a shield (25) against deposits of weaving dust, which is arranged between the cross strut (18) and the lower chain (23).
- the shielding (25) shown in FIG. 1 is formed by a profile, the upper side (26) of which, when the shed is open, runs essentially parallel to the lower chain (23) and almost touches it, so that the warp threads (21) of the lower chain (23) keep a small distance from the top (26) of the shield (25) or even touch it.
- the upper side (26), which lies closely opposite the lower chain (23), is essentially flat and smooth.
- the profile can consist, for example, of a folded sheet metal.
- FIGS. 2 and 3 show a first embodiment of a shield (25) for the cross strut (18).
- Arranged on the cross strut (18) are, for example, welded-on supports (27) which are provided with elongated holes (28).
- the shield (25) is provided with folded tabs (29) in which elongated holes (30) are arranged which run perpendicular to the elongated holes (28).
- tabs welded to the shield (25) can also be provided. Screws (31), which are provided with nuts, are inserted through the elongated holes.
- the elongated holes (28, 30) and the screws (31) provided with nuts are adjustable fastening means which make it possible to fasten the shield (25) to the cross strut (18) in such an adjustable manner that the top (26) of the shield ( 25) is aligned with the lower chain (23) in the desired manner.
- the position of the lower chain (23) is essentially determined by the position of the holding parts (4).
- the adjustable fastening means from the elongated holes (28, 30) and the screws (31) make it possible to adjust the shield (25) vertically and horizontally and thus also in the inclination to the cross strut (18), so that the Top (26) of the shield (25) can be aligned precisely and parallel to the lower chain, ie at a distance of a few millimeters from the lower chain (23).
- the shield (25) is also provided with two sections (32, 33) adjoining the upper side (26), which are oriented essentially vertically and which extend downward beyond the cross strut (18) and shield them. These sections (32, 33) prevent weaving dust from reaching the cross strut (18) from the side. They guide any weaving dust down to the dust collecting cloth (17).
- the dust collecting cloth (17) runs essentially vertically, so that the weaving dust falls down and is removed by means of a conventional dust extraction device that moves in a weaving room. direction can be removed. It is thus not only prevented that no weaving dust is deposited on the cross strut (18), but also additionally ensures that the weaving dust is directed to a location from which it can be removed in a simple manner.
- the arrangement of the shield (25) on the side of the lower chain (23) facing the warp beam (2) is advantageous because most of the weaving dust is released there, which can then be passed in a simple manner to a location from which it can be removed can.
- the section (32) of the shield (25) is dispensed with. This is possible because the weaving dust that falls between the shield (25) and the weaving frame (9) moves in the direction of the arrow (P), so that the risk of this weaving dust falling onto the cross strut ( 18) arrives.
- two supports (27) are attached to the cross strut (18), on which an axis (34) running parallel to the cross strut (18) is arranged.
- the shield (25) is provided between the sections (32, 33) with a plurality of transverse webs (29), each of which is clamped to the axis (34) by means of a bracket (35) and screws (36), so that the shield (25) about the axis (34) can be pivoted and tightened. This makes it possible to adapt the inclination of the upper side (26) of the shield (25) to the course of the lower chain (23).
- the sections (32, 33) of the shield (25) are provided with elongated holes (37) through which screws (38) reach, which are fastened to the transverse webs (29).
- the shield (25) By loosening and tightening the screws (38), the shield (25) can be adjusted vertically so that the distance between its upper side (26) and the lower chain (23) can be set exactly.
- the axis (34) is fastened to the supports (27) by means of a U-shaped bracket (39), the ends of which penetrate the cross strut (18). The ends are provided with an external thread onto which nuts (40) are screwed.
- the shield (25) is composed of a plurality of profiles which are arranged one behind the other in the longitudinal direction of the cross strut (18) and form a continuous shield (25).
- Such a shield (25) is particularly advantageous in the case of very wide weaving machines.
- Such a divided shielding is also advantageous if components have to pass through the shielding (25).
- each of these cross struts is assigned a shield (25) according to the invention.
- a common shield (25) is provided, which then extends with its upper side (26) over a plurality of transverse struts (18).
- cross struts (41, 42) are provided between the side parts (1) of the weaving machine in the embodiment according to FIG. 1. These cross struts (41, 42) do not require shielding (25) of the type described, since on the one hand they are less exposed to the risk of dust deposition and because there is also less risk of dust accumulations or the like. from these cross struts (41, 42) to the warp threads.
- the invention can also be used with advantage in weaving machines that do not have a warp thread guard device (8) with a shed shed support (8A) and / or no weaving frame (9).
- the weaving machine can have an independent shed support.
- the invention in a jacquard weaving machine which has harness cords for lifting and / or lowering the warp threads (21). In this case, a rear compartment is formed between the harness cords and the separate shed support. A shield corresponding to the shield (25) for a cross strut is then arranged in this area in the manner described. 6. Loom according to claim 5, characterized in that the shield (25) is adjustably attached to a Querstre ⁇ be (18).
