"Loom"

The invention relates to a weaving machine with a machine frame, a warp beam and a fabric tree (trees).

In known weaving machines, the warp beam and the Tree of goods in each case directly on the machine frame, z. B. stored in the side walls of the machine. As a result, the usable diameter of the trees is relatively narrow Limit set, for example, often only warp beams with a largest diameter of 600 mm can be used. To one To build a larger warp beam, it is also known to tilt the machine, d. H. to be lifted on the warp side. Through this As a rule, a warp beam with a diameter of 800 mm or a little more can be used.

The warp threads should as far as possible over their entire length between the warp beam and the edge of the goods (reed stop point) be easily accessible for the operating personnel. For this reason

109817/1687

cannot exceed a certain height of the loom will. In order to use a warp beam with a diameter greater than 800 mm in the machine frame, the loom would have to be be raised so far that the staff can handle the threads, for example when fixing warp thread breaks or would be hindered when working on the shafts, etc. In general, it is also not advisable to run the machine on the Heat side to be raised, as from this side z. B. Weft yarns and the shafts should also be easily accessible across the entire width of the machine.

So far, a VJarenbaum has been wrapped up to a diameter of approx. 500 mm, whereupon the fabric is cut off,

the full tree was removed and a new, empty tree was inserted. This process has to be repeated several times until the entire chain is detached. Depending on the operating conditions or the type of fabric to be produced - for example in cotton weaving mills for staple items when processing Continuous yarns as well as for the production of backing fabrics for the carpet or pneumatic tire industry - however, is used for the more Processing, e.g. B. for printing or dyeing the fabric or

109817/1687

for applying the carpet pile for reasons of economy Often the greatest possible length of goods is desired in one piece.

Another requirement for an economical weaving operation is that by replacing the warp beams or to reduce machine downtimes caused by the respective preparation of the warp. One is therefore in strives for such cases, both wareri beams and warp beams to be used with the largest possible winding diameters. Such warp and fabric trees cannot be used on the known weaving machines be attached because they hinder their ease of use.

It is also known to use the warp beam over the heald frames to be arranged on a support frame supported on the machine frame. With this arrangement, a large warp beam can be used, but not a correspondingly large fabric beam. Besides that can the fluff and Sizing fall onto the underlying warp threads and into that Reach shed, whereby z. B. Web errors can arise. There is also access to the warp thread monitors and the heald frames from the rear side (warp construction side) of the machine through the blocked warp threads fed in above. Furthermore, there is this

109817/1687

Arrangement there is a risk that the vibrations of the machine on the relatively heavy warp beam support frame supported on it be transferred.

The invention is intended to avoid the disadvantages of the known arrangements mentioned and to create a loom which - without changing the overall height of the machine frame and without too much additional need Floor area - can be equipped with significantly larger trees than before, the diameter of which is independent of the machine height can be selected according to the respective operating conditions.

The invention consists in that the warp beam and the fabric beam are located on an outside of the machine frame Support structure are stored in storage devices arranged essentially one above the other. With this arrangement the insertion and removal of the trees is essential compared to so far simplified} warp and goods trees of z. B. 1'2OO mm diameter and more can be used, so that especially long running times of the machine or large piece lengths of the finished fabric can be achieved. Furthermore, the replacement of the

109817/1887

180Ü7S9

-D-

Trees and a machine overhaul that may be required - Cleaning, lubricating, etc. - take place at the same time, which is not possible with machines with trees stored in the machine frame is.

In an advantageously compact design of the invention g , the support structure for the warp beam and the fabric beam is designed as a structural unit.

In order to ensure accessibility of the machine from all sides, according to a further embodiment of the invention, the warp or the finished fabric from the warp beam or from a deflection element located on the fabric side of the machine frame are initially downwards and each via a near the bottom of the - »Weaving arranged deflecting element along the floor to a further deflecting element and from this up to a deflecting element arranged on the warp side of the machine frame or to the tree, the trees being arranged at such a distance from the loom that between, this and the A room that can be entered by the operating personnel remains free for the trees.

To monitor the entire length of the warp

109817/1687

1,8007 69

the support structure is preferably on the warp side the loom arranged, the accessible space is limited laterally and downwardly by the essentially U-shaped part of the warp, while the finished Fabric from the fabric side of the machine under the machine "

and is guided to the tree of goods between the floor and the warp. In this arrangement, all of the warp threads are for the operating personnel accessible, so that the necessary during web operation Work such as B. the checking of the warp thread monitor lamellae or the elimination of warp thread breaks, without Disability can run.

An advantageously low load on the building structure is in a design according to the invention by e ^ ine supporting Connection between the machine frame and the supporting structure achieved, at least part of the through the Weaving forces caused by the storage of the trees can be transferred to the machine frame, with which there occurring forces result in a compensation.

In a further embodiment of the invention, the abrasive Connection of beams on which the machine frame stands,

109817/1887

As a result, the weight of the machine frame can counteract a moment exerted on the supporting structure, for example. In addition, the position of the trees or the leadership and deflection elements for the warp and the fabric as well as for the Drive means of the trees with respect to the machine frame are precisely observed.

To increase the stability of the supporting structure, the supporting connection contains in one embodiment According to the invention, a connecting strut arranged above the accessible space.

In order to make particularly good use of the available floor space of the weaving mill, the supporting structure contains further training the invention at the same time storage devices for the trees of an adjacent loom. This allows the distances between the machines are advantageously kept small despite the use of large trees.

In order not to damage the parts of the warp or the fabric running along the floor, but still accessible is to be kept in an embodiment according to the invention between the machine frame and the supporting structure

109817/1687

a movable pedestal arranged in the accessible room.

In a design according to the invention, the platform is provided with rotatably mounted guide rollers and with these on two deflection elements located in the area of the accessible room stored. The platform preferably contains four guide rollers, with at least two of the guide rollers one have profiled running surface according to the profile of the associated deflection element. The length of the pedestal is preferred smaller than half the weaving width, so that by moving the platform accordingly, the warp bz% *. the mesh is accessible across the board.

this can be moved so far between the two vertical parts of the warp 10 that a sufficiently wide gap remains free between one - * to fix thread breaks that occur when the warp threads are running.

The loom 2 is driven by an electric motor 54 via a belt drive 55 and a flywheel 56 This sits on a main shaft 57, from which the movements all mechanisms belonging to the machine, such as B. the heald frames 38 and the reed 42 and the warp beams 21, 22 and the goods tree 26 are derived.

The warp beams 21, 22 are arranged via two each on the mutually facing inner sides of the side cheeks 5, 6 Sprockets 58 driven, which via a not shown Differential gears are connected to one another and to the main shaft 57 driven. In Fig »1, the drives of the The warp beam 22 of the machine 2 and the warp beam 21 'of the adjacent machine are visible; the warp beams are 21.22 x (Fig. 2) driven in the same way. From each of the two sprockets

The chain wheel 65 is arranged on the side of the machine 2 on its side cheek 6 and is driven from the main shaft 57 via a slip clutch 66. From the chain wheel 65 is an endless drive chain 67 via two pairs of deflection claws 68,69 mounted on the web of the carrier 12 - under the machine 2 through - to a sprocket 70, which is mounted on a center line running between the warp beam guide rollers 24,25 on the web of the carrier 12 * The sprocket 70 is connected to a pinion 71, which is connected to two gif ich gyos sen gears 72,73 in Intervention is. These are each connected to the guide roller 24 and 25, respectively. _{The driving forces of the guide rollers 24 9} 25, which are each provided with a rough surface, are caused by friction

The warp beams 21, 22 | According to arrow 74 (FIG. 1), intermittently rotated, see above that a warp length corresponding to the withdrawal of goods is let off. The tensioning tree 36 provides the required tension in "the warp threads produced * According to the respective position

of the spanning beam 36 is also the drive for the warp beams 21, 22 controlled in a manner known per se. If, for example, a warp length that is too small compared to the goods withdrawal is withdrawn, the Spanribaum 36, which the tension of the warp 10 is constant holds, pivoted slightly downward in Fig. 1 about the pivot point 35. This is a switching device, not shown a slip clutch belonging to the warp beam drive influences so that the sprockets 58 during a larger Period of time are driven and thus a correspondingly larger Warp length is released from the warp beams 21,22. Conversely, if the warp length is too great compared to the goods take-off is, the spanning tree 36 moves upwards, whereby

109817/1687

the sprockets 58 are driven for a shorter period of time, so that a correspondingly smaller chain length is drained. By connecting the two chain wheels 58 Differential gears, tension differences between the warp thread groups running off the two trees 21,22

pen avoided.

The finished fabric 30 passed under the machine from the goods side of the machine 2 is placed on the goods tree 26 wound, which by the guide rollers 24,25 according to arrow 75 is set in rotation intermittently. At the beginning of the weaving operation, the goods tree 26 takes its lowest Position 26a, in which he z. B..the leadership role 25 is

^w stirs while there is a layer of fabric between it and the guide roller 24. As the winding process progresses, this first fabric layer passes between the tree 26 and the guide roller 25 and then under the second fabric layer that has meanwhile been supplied, so that the tree 26 is lifted and the frictional forces of the guide rollers 24, 25 act on the resulting fabric reel 30a. As the winding diameter increases, the fabric beam 26 - together with the loosely inserted guide tube 27 - is raised until it reaches the position shown in FIG

109817/1687

drawn position reached. The guide tube 27 guided between the carriers 16, 17 ensures that the Tree of goods 26 always has a central position above the guide rollers 24.25, in which the roll rests on two guide rollers 24.25.

On the ceiling of the weaving room 1, ^{a horizontal carrier 77 is arranged above a center line running between the supporting structures 76, 76 r} parallel to the axes of the trees 21, 22, 26, to which a running rail 79 is attached by means of holders 78, which as Suspension track for hoist * 80 is used. The girder 77 is connected to three girders 81 and 81 'which are connected at right angles to the ceiling in the area of the two carrying structures 76,76' and which are guided parallel to the girders 11,12 over the looms opposite one another (Fig. 2). 78 rails 82 ^ 83,84 and 82 ', 83 ", 84" are on the carriers 81,8I ¹ also attached to holders, each of which is connected via a bent in known manner with a switch provided intermediate piece .85 with the running rail are.
