Patent application arrangement on a loom

The present invention relates to an arrangement on a weaving machine, in which thread pieces of a predetermined length are formed as from individual "indungen existing windings on a winding body and means are available to the Moving the windings along the winding body without the thread to cut.

It is known to supply pieces of thread of predetermined lengths create and these pieces of thread, polygons of the width of the to be produced Fabric are the same as weft threads individually between

Insert the warp threads and use them. In special colchon processes, threads of thread are continuously drawn onto a thread, with a given number of threads forming a winding, which embodies a piece of thread of such predetermined length .

For the further use of the windings continuously formed in this way, the exact position of the individual Turns on the winding body are essential, i. E. eo no undesired changes in position of the same should take place on the Vicklungskörper. In particular, this should also be the case Be the case when the individual windings along the winding body be kept at a mutual distance to form separate coils. This is to be achieved Object of the present invention.

When using such windings in a polyphase "Weaving process, i.e., in a weaving process in which If a plurality of entry organs or shuttles move through the shed at the same time, a predetermined number is periodically set of turns in the longitudinal direction of the winding body moved into a transfer position without cutting the Thread takes place between the individual windings. In the Ueberr The windings are handed over to the shuttle at the point of delivery. When sliding along the winding body, it can happen that that those turns of the windings »on which the pushing force has the most direct or strongest effect »after quitting look back a little bit. This means that their location is closed

On the other hand, it can easily be precorrr.cn, ckiss toi one Sucheii pushing a winding lMngc of the Wickliuigokörpor, which only * or some of the turns immediately after this winding to be partly dragged along. As a result, the clean formation of the winding to which this entrained winding belongs or suffers. these dragged turns belong. If windings are drawn along in this way when the weft thread insertion crigon to be transferred Winding is withdrawn from the winding body, so stuff like that Winding can be completely unwound from the winding body. As a result of this, this weft thread is then woven as a double thread, i.e. there is a weaving error.

These two disadvantages mentioned above are intended to be avoided according to the present invention. This is because of it characterized in that at least one holding member is provided, which can be actuated in the rhythm of advancements of the windings taking place along the winding body in order to hold the windings located on the winding body in predetermined positions.

The invention will now be described in detail using exemplary embodiments and the drawing. In this shows

For the purpose of weaving, a plurality of nut thread insertion organs in the form of shuttles 18 are provided, which move through the shed 17 simultaneously and one after the other. The entry members 18 are moved forward by the blade lamellas 19, which work as drive members. These also serve to strike the inserted weft threads against the fabric stop 60. The warp threads 12 ensure that the input members 18 are guided in the compartment 17. The lamellas 19 are built into the arrangement 28, which is firmly attached to the loom frame 29. To generate the movement of the leaf lamellae 19, two worm shafts are provided, which are not visible in FIG. When the worm shafts 21, 22 rotate, the blade lamellae 19 are pivoted about an axis in such a way that each lamella 19 lags behind the one in front of it by a small amount. 1 wave movement propagating from right to left, .by which the shuttle 18 is carried along. The woven fabric 23 is wound up on the fabric beam 26 via the draw-in roller 24 and the pressure roller 25 ^. At 27 a temple is indicated.

An outlet box 20 is provided on the right-hand side, from which the empty weft thread insertion members 18 are delivered in a continuous sequence. Next to the outlet box 20 is located a blade-shaped bobbin 21 on which thread windings of a predetermined length. The thread used to form this Windings are removed from the thread spool 22 and wound by the rotor 34. ·. ■; ■■ t

The structure of this arrangement is shown in FIGS "Better to see. In the drain box '20 this is for the transfer of the winding 30, v; elcho represents a piece of thread of predetermined length, available shuttle 18 available. The winding. "is located on the blade 21 in its delivery position, i.e. in readiness to be handed over to the shuttle 18. The blade 21 is supported by means of the ball bearing 31 and against Rotation held by a support rod 32. The ball bearing 31 is from the rotatable axis 33 »to which the rotor 34 is firmly connected is worn. The rotor 34 carries a thread eyelet 35 »through which a thread 36 is pulled. The thread 36 runs from the one shown in Fig. supply reel 22 shown through a channel 37 in the axis 33 and through the eyelet 35 to the blade 21, on which it is wound. At the front V / and 38 (see also Fig. 3) of the discharge box-ems there are also two resilient arms 39 and 40. These are with their one 2nde using the screws 41, respectively. 42 attached to the front wall 38. On their other 2nd «they wear the holding links 43 resp. 44. The latter are through in the example shown Bending over the corresponding ends of the arms 39 »40 have been formed. As a result of the elasticity of the arms 39, 40, the holding members 43, 44 exposed to constant pressure against the blade 21. They reach through the opening made in the front wall 38 46 through. Finally, a pin 52 is shown in FIG. 2, which is carried by the Vinkelb'lech 51 and which serves to push the arm 40, so that its holding member 44 from the Blade 21 lifts off. As already mentioned, FIG. 3 shows a section of the arrangement seen from the right according to FIG. 2.

Thus, since the pin 52 would not be visible in FIG. 3, it is shown in FIG Servant Pi car 3 Drawn with dashed lines. 'For moving the thread windings The needle 50 serves along the line 21. This is both laterally, that is, parallel to the longitudinal axis of the .Klinge 21, as well as after Movable at the front and back. So that this is possible in the blade the longitudinal slot 45 is present.

From the side view shown in FIG. 3 it can be seen that the needle 50 is carried by a running rail 54, which is movable perpendicular to the plane of the drawing of FIG. The drive In the example shown, the running rail consists of the one around the axis 58 pivotable lever 56 which can be pivoted by means of the crank disk 57 is. Die.Schwenken the lever 56 takes place by the Crank disk 57 fixed pin 49 during its rotation in an im Arm 56 mounted, in the longitudinal direction of the same extending slot with reciprocating movement in this slot, the Arm 56 takes with it. In a second longitudinal slot 'in the arm 56 is the Pin 48 held displaceably. As a result, the pivoting of the lever 56 results in a reciprocating movement of the tab 55 and the fixed with it connected running rail 54. This is the desired displacement of the needle 50 to move the turns along the Blade 21 received.

The running rail 54 is carried by the angle plate 51 and this in turn by the bolt 53. The connecting link is on the angle plate 51 or the pin 52 attached, which is used to lift the resilient Arm 40 serves, in the further the bolt 53 is carried in the bearings 60 and in these, as indicated by the double arrow,

can be moved parallel to itself. This parallel shift ■ is obtained by means of the control cam 59. Such a displacement entrains the push member 52 and the needle 50 '. Since the tab 55 is also taken along with this shift, must be the length of the above-mentioned longitudinal slot leading to pins 48, be dimensioned so that it also allows this parallel shift. It can be seen that the movement of the pins 50 and 52 coupled to one another in the direction parallel to the axis 53 are and take place at the same time. The displacements of the running rail 54 in the direction perpendicular thereto, which are caused by the parts 57 and 49 are generated, take place in relation to the movements caused by the control cam 59 in a certain way mutual rhythm ..

It has already been mentioned that arms 39 and 40 are at their free end a holding member 43 respectively. 44 wear. An example embodiment of such a holding member is in Fig. 4 shown. The holding member 43 is designed as a section arranged obliquely at the free end of the arm 39. The in Fig. The view of the same as shown is a view in the direction of the arrow 61. The holding member 43 can be formed as a bent part of the arm 39, but it can also be along a region 62 with the Arm 39f can be connected e.g. by welding. The holding member 43 has a flat curvature 63, with which it is shown in FIG State rests on the blade 21. It also has a nose-shaped projection 64. The arm 39 is positioned so that • that in the state in which the holding member 43 with its flat Curve 63 rests on the blade 21, the nose 64 in one in the

Blade 21 dips into existing opening 47. The shift of the - Thread turns takes place in the consideration of Figures 2 and 4 of 'right to left, sodacs seen in that direction, first the flat curvature 62 and then the nose-shaped projection 63 is arranged is. ;

When the loom is in operation, the entry organs or shuttles 18 move, as shown in FIG. 1, in continuous succession through the shed, each shuttle 18 inserting a weft thread. The rotor 34 rotates during this weaving process permanent and forms 21 turns on the winding body, the thread 36 being continuously withdrawn from the thread supply 22. Included rotates the rotor 34, viewed from the right in FIGS. 1 and 2, clockwise. The blade 21 stands still because it is prevented from rotating by the holding rod 32 (FIG. 2) and because the parts 21 and 34 only rotatable, connected to one another via the ball bearing 3-1 » are. In this winding process, the individual turns, which are created from the front, slip during the winding process immediately below the top edge 64 between the blade 21 and the support rod 32 therethrough. Slide during the wrapping process the turns immediately to the left ends of the inclined edges 64 and push the turns of the thread that are already there. 36 to the left. So that the shifting of turns, which always takes place to the left, takes place easily along the entire blade 21, also has the part of the blade or the winding body3 21 which is located to the left of the area lying between the edges 64 a slightly decreasing cross-section towards its free end. '

109887/0532

Having such a number of turns living together are wound up so that the resulting winding is one for the snow ' entry has a predetermined length, the needle 50 is in the position 65 moved forward, i.e. pushed through the longitudinal slot 45 present in the blade 21. On the other hand, a The shuttle 18 is pressed down and over the blade 21. For this purpose, the shuttles 18, as can be seen from FIG. 3, are at the bottom and open on the sides. During the downward movement of the shuttle 18 in the direction of the Pig. 3 shown arrow 66 pushes this resilient arms 39 and 40 away from their abutment with the blade 21. to For this purpose, the holding members 43 »44 are arranged obliquely in relation to the thrust of the shuttle 18 that they be pushed away by the shuttle 18 moving towards and over the blade 21. The holding members 43, 44 are, in other words printed out, of their attachment to the arm 39, respectively. 40 directed obliquely downwards. As the needle 50 moves forward, it becomes like already described and as can be seen from FIG. 3, the pin or the push member 52 is also moved forward. This becomes the resilient Arm 40 raised from shuttle 18.

The needle 50 then moves out of position 65 to the left in its position 50 shown in FIG. 2 and moves a new winding 30 of a pre-measured length into the transfer position, where it will be taken over by the next shuttle 18. Simultaneously with the displacement of the needle 50 from its position 65 to the left, the shuttle pushed over the winding 30 shown in FIG. 2 is also pushed to the left. The shuttle 18 points

109887/0532 BADOBiGlNAL

inside a velvet covering, which the turns of the winding 30 holds. The "latter" becomes --- thus through the movement of "the" shuttle 18 Itngs of the blade '21 'peeled off from this and is now in cleaner Order stored inside the shuttle 18. With renewed reference On FIG. 1 it can be seen that the shuttle, which has been cast away to the left by the blade 21, is then taken over by the lamellae 19 and is guided through the shed. .

When the shuttle 18 moves away from the blade 21 now the danger that the first of the boat 18 no longer captured Twists of thread, polygamy belong to the next winding pulled out to the left and that possibly even a partial unwinding of the same from the blade 21 could take place. To do this avoid, the support member 43 carried by the resilient arm 39 is provided. At the moment when the rear side of the shuttle 18 Moved away from under the holding member 43, this is due to the clamping force of the arm 39 is pressed against the blade 21, the nose 64 moving into the opening 47. This makes the immediate behind the shuttle 18 subsequent turns in a defined Position held exactly, whereby the windings 30 predetermined thread lengths become very precise in their length. It can be seen that the curved region 62 causes a clamping of the thread 36, which also prevents displacement of the same in its longitudinal direction. But should a slip of a turn of the thread 36 under the Curvature 63 takes place once, so the nose 64 still and with complete certainty prevents that this curl further than up can slide to nose 64. .

As already mentioned, the resilient arm 40 is moved forwardly away from the blade 21 and from the shuttle 18 by the pin 52 pressed as long as the needle 50 and thus the pin 52 forward are moved. After a winding 30 through the needle 50 equals * - at the same time as a winding 30 is stripped off by a shuttle 18 has been moved back to their transfer position, the needle 50 and pins 52 move back to their rearward position. There when moving along the blade 21 to the left, especially the rearmost ones Threads of the new winding 30 are pushed through the needle 50 own they have a tendency to slide back slightly to the right after the needle 50 is withdrawn. If this happens, it can be that subsequently when the shuttle 18 is pushed onto this new winding, the last turns of the same are not clean and can be safely detected by the shuttle 18. To avoid this, the holding member 44 carried by the arm 40 is provided. With the withdrawal the needle 50 to the rear, the holding member 44 lies on the blade 21 and in combination with this forms a holder, which these last turns of the winding 30 in their due to the movement the needle 50 holds the set rest position. The holding member 44 remains so.lange in contact with the blade 21 until it through the next following shuttle 18 is pushed away again when this in the direction of the arrow 66 shown in Fig. 3 over the new Wiödung 30 is pressed.

The shape of the holding member .44 can be that of the holding member 43 accordingly. However, since the prevention of displacements of turns in the longitudinal direction requires relatively less force in this last-described process, a shape is sufficient,

109887/0532 badoriginal

which only has a curved area 62. But it is also one -Shape advantageous for the holding member 44, as shown in FIG is. As is readily apparent, the member 44 is through a approximately rectangular plate formed, which in the actuated state rests with its free end edge on the blade 21.

It was mentioned that the holding member 43 comes to rest with the blade 21 as soon as the rear edge of the shuttle is moved away from the point where the opening 47 is located. If you work quickly, it could happen that the · W first turn of the new winding already slipped through at this point 47 is before the link 43 comes to rest. In order to achieve an even further improvement, the shuttle 18 can be the in Fig. 6 are given the shape shown. The clarity is in this figure the front wall 38 of the discharge box 20 in the area of Transfer point thought to be left out. The shown shuttle 18 has an indentation 65 in its rear part This is located are at such a height that they are pushed over the blade

The shuttle 18 is at the level of the holding member 43 and the opening ^ 47 is as shown in FIG. As a result of this indentation 65, the holding member 43 reaches its contact with the blade 21 earlier than in the form of the boat shown in FIG This is the case and an error-free way of working is ensured.
