Definitions

  • the invention relates to a method for loom conditioning according to the preamble of claim 1 and a weaving machine.
  • conditioned air is supplied both through ceiling outlets distributed in the room and through local outlets.
  • a local outlet is provided for each machine, which has a slit-shaped outlet opening at a distance above the warp.
  • the local outlets are arranged under the warp. In both cases, the outlet opening extends approximately across the full width of the warp and releases a jet of conditioned air directed against the warp.
  • the object of the invention is to provide a method which brings effective conditioning with a considerable reduction in the air-conditioning costs per weaving machine by means of reduced power requirements and air volume flow and smaller water consumption, without an impermissible indication in terms of visual appearance or accessibility to create employeeis.
  • a piston-like displacement flow is understood to be a low-turbulence flow with an approximately uniform distribution and approximately the same speed over its full cross section. Exit speeds of between 0.3 and 1.2 / sec come into consideration.
  • the invention is based on the knowledge that the transport of moisture with an air jet blown out of a slot-shaped outlet opening is not very effective and is therefore uneconomical. This is mainly due to the relatively high exit velocity necessary for the throughput of the required amount of air. Studies show that for the time being, a significant proportion of the blown-out air does not reach the (as yet unwoven) warp threads. In addition, some of this air bounces off the warp without being able to release its moisture. This means that heheblic ⁇ more conditioned air has to be conveyed than the weaving chain has in order to achieve the desired relative humidity.
  • the displacement flow used according to the invention allows the required exit velocity to be reduced considerably compared to that from a slot-shaped outlet opening with the same distance to the warp to be covered.
  • the displacement flow hitting the chain does not bounce off, but is mainly deflected.
  • This deflection takes place gently and while maintaining the piston-like character in order to flow off along the warp threads, mainly in the direction of the warp beam.
  • optimal moisture is immediately present made of the chain and keep it largely dust-free.
  • the air conditioning costs can therefore be significantly reduced.
  • the piston-like displacement flow allows conditions within its cross section to be created and maintained which are different from those in the environment.
  • the design of the cross-sectional shape and dimensions enables the climate of one zone on a textile machine to be controlled in relation to the required properties. Flight and dust from the surroundings are also prevented from entering this zone. If this is required, several zones on a machine or in the delivery area of the textile material can accordingly be controlled by a piston-like displacement flow, the climatic conditions in which can be interpreted differently.
  • Piston-like displacement flows can therefore also be used advantageously for air conditioning other textile processes and processes such as use when carding, laying down, storing and picking up the fuse from the jug, stretching and spinning, and twisting.
  • FIG. 1 schematically shows the conditions on a weaving machine equipped with a device according to the invention when using an embodiment of the method
  • FIG. 2 shows a vertical section along line II-II in FIG. 3 through the local outlet of the device according to FIG. 1 and shown on an enlarged scale
  • Fig. 3 is a bottom view of the local outlet according to FIGS. 1 and 2, shown partially broken away.
  • FIG. 1 generally designates a weaving machine with a warp beam 4, thread monitors 6, a shaft package 8, a drawer 10 and a goods beam 12.
  • the warp threads that run over a match tree 14 and form the warp 16 are denoted by 18 and the rear shed of the shed adjoining the thread monitor 6 is indicated at 20.
  • a local outlet 22 is arranged above the weaving machine 2 and at a distance from the warp 16 or the rear shed 20 a line 24 is supplied with air-conditioned air from a climate control center 26.
  • the local outlets of all further weaving machines of the weaving room are also connected to the same air-conditioning center 26.
  • the local outlet 22 has an outlet opening 32 directed downwards against the warp chain 16 and extends horizontally over the entire working width of the weaving machine 2, the outlet opening being directed approximately at right angles to the general course of the weaving chain.
  • the design of the local outlet can be seen from FIGS. 2 and 3.
  • the local outlet 22 comprises a box 30 of elongated shape with a constant rectangular cross section over its longitudinal extent.
  • the box 30 is closed on all sides except for the underside forming the outlet opening 32.
  • the bottom and top represent the broad sides of the rectangular cross-sectional shape of the box.
  • the interior 40 contains distribution elements in order to distribute the air flowing in through the inlet opening 38 evenly over the surface of the outlet opening 32 and to generate the displacement flow provided according to the invention.
  • these distribution members comprise a perforated plate 42 which is parallel to the upper side 34, but at a distance therefrom over a central longitudinal region and the full width of the interior 40 extends.
  • the length of the perforated plate 42 fastened by bolts 44 to the top 34 of the box 30 is greater than the diameter of the inlet opening 38, but less than the length of the interior.
  • a further perforated plate 46 which is attached to the side walls of the box 30 or is suitably supported on the underside.
  • this perforated plate 46 is limited to a dimension that is somewhat smaller than the diameter of the inlet opening 38.
  • the passage cross section formed by the perforation of the perforated plates 42 and 46, based on their area, preferably makes up between 35 and 45%.
  • the last distribution element in the interior 40 of the box is an air-permeable mat 48, e.g. from a corresponding foam which is clamped between a peripheral flange 58 of the box and a grid 50.
  • Mat 48 and grid 50 extend the full length and width of the interior.
  • the grid 50 which is formed, for example, by a wire grid of relatively large mesh size, is supported on a narrow frame 52 provided on the underside of the box.
  • the frame 52 delimits the outlet opening 32 with the length 54 and the width 56.
  • a foam with a pressure loss of 15-20 Pa at 0.6 m / sec has proven to be suitable for the mat 48.
  • the Box 30 represents an air distributor 60.
  • the described design and arrangement of the distributing members in this box result in a gradual distribution of the air flowing through the inlet opening 38 into the interior 40. Only a part of this air can pass through the perforated plate 42, which also acts as a baffle plate opposite the inlet opening, in the direction of the arrows 62, while the rest is deflected on opposite sides in the longitudinal direction of the interior 40 with little pressure loss without opening the further route to the mat 48, ie in the direction of the arrows 64, to have to overcome a flow obstacle. In order to reduce the speed in the partial flow flowing without deflection in the direction of arrows 62, this must still overcome perforated plate 46.
  • the partial flows 62 and 64 therefore reach the mat 48 at approximately the same speed.
  • a fine distribution of the air takes place on the mat 48 and when it passes through it, a piston-like displacement flow is formed which is formed from the finest flow threads.
  • a limitation to values between 0.5 and 0.8 m / sec is indicated in the present context.
  • the air quantities can thus be designed differently within certain limits even with the same dimensions of the air distributor 60.
  • the air-conditioning center supplies conditioned air which exits from the local outlet 22 formed by the air distributor 60 (FIG. 1) as a piston-like displacement flow 70, e.g. B. exits vertically downward at an exit speed of -0.6 m / sec and, according to dimension 56, has a width of, for example, 300 mm.
  • the displacement flow defines the distance, for example 0.9 m, to the upper one
  • the warp thread sheet 20 'of the shed 20 returns in a compact form and hits the shank package 8 in front of it. When it strikes this and the lower warp thread sheet 20 ′′, the air is deflected at least as a larger partial flow 72 against the thread monitor 6 and flows along the warp threads 18 against their delivery direction.
  • a partial flow 74 flows along the corresponding warp threads in the shed area and flows down between them. Both partial flows of this air in the vicinity of the warp 16 create a climate suitable for transport and processing, in that heat and dust are removed and the relative humidity is kept at an advantageous value. Since the warp threads 18 are washed around by the flow over a long period of time, there is also a direct absorption of moisture, which has a favorable effect both for the weaving process and for the water consumption. In particular, this applies to the influence of the partial flow 72, which flows along the warp threads, envelops them and shields them from the ambient air.
  • a distance of approximately 1.2 m from the local outlet from the weaving chain running below represents an upper limit for economic reasons.
  • a bottom opening 80 is expediently provided below the weaving machine 2 in a manner known per se, through which dust-laden air is removed.
