Loom

The invention relates to a loom with a g Jacquard machine for controlling the warp threads and a More weft mechanism for changing the weft threads to be inserted. Under the multi-shot mechanism is a shooting device to understand through which it is made possible * after a program of weft threads of different types, e.g. different Color, different material, etc. to be entered in the shed. For example, the following is the change of weft threads of different colors (multicolor weaving machine) f assumed i

In a previous loom of the type mentioned the jacquard machine is only used to control the warp threads. The multi-shot mechanism is controlled by a separate control device, e.g. a card shaft machine, which determined the color sequence of the weft threads to be inserted Contains program on a_hole card. The machine has no shafts for the warp threads, as these are through the

209817/0183

Jacquard machine can be controlled. The card socket broker is only used to control the multi-shot mechanism.

The object of the invention is the controller to improve and simplify the multi-shot mechanism.

The invention consists in that the multi-shot mechanism controlled by the jacquard machine. A separate one, only control device required for the multi-shot mechanism like ζ.Β. a card socket machine is then unnecessary. the Jacquard machine is used to control the warp threads and the multi-weft mechanism at the same time.

In a Ausführungsforra according to the invention is in the geared connection of jacquard machine and multi-shot mechanism at least one energy storage device for the temporary one Storing the control motional energy supplied by the jacquard machine switched on. In this way, it is possible to time the outgoing from the jacquard machine in Settlement linked to each work cycle, each of which is based on The time of the shed change must be set for the time required at other times during the work cycle, essential to use faster than the switching movement of the reversing shot mechanism. The control motive energy the jacquard machine can be stored in the control force spoke:. and stands for the later to be initiated, particularly rapid switching of the multi-shot mechanism to disposal.

209817/0183

In one embodiment according to the invention, a power drive, e.g. an eccentric or crank drive, and at least one power store actuated by this for the temporary storage of the switching movement energy supplied by the power drive for the sweeping shot mechanism is switched on in the geared connection of the control force accumulator and the sweeping mechanism , whereby a lifting plate of the control force accumulator can be coupled with drive parts of the power drive in accordance with the program of the Jacquard machine. m

The actuated by the jacquard machine control force memory ä then be sized for small forces, so that the applied by the jacquard machine and usually passed over cords force for the movement of the control memory need not be large. A much greater force required for the rapid switching of the reverse shot mechanism can be made available by the power drive and passed to the changer of the multi-shot mechanism via a switching force storage device designed for large forces. Switching J of the reciprocal firing mechanism can be particularly surprising run like then, so that this does not require a lot of time during each working cycle of the loom.

In a design according to the invention is one of the Loom controlled locking device built in to lock the lifting plates during the storage process in the control force store. The ones made by the jacquard machine

The machine has a bobbin support frame 87 with thread balloon limiting screens 88. Weft supply bobbins 89a to 89d are arranged between the boundary screens. . During operation, a weft thread 10 is withdrawn from a bobbin and in a shuttle guide 14 by means of a weft thread guided hook protection 12 registered in the subject. Included the weft color corresponding to the weft repeat is set by the four-shot mechanism 86 and the Protect 12 by parts described in more detail below.

™ leads. The shooter 12 is shot down by a firing mechanism 13 and runs up to a catching mechanism 15. At the edge of the chain 22, near the works 13, 15 there is a respective edge strip laying device 16 appropriate. This contains a centering device for centering of the respectively entered weft thread 10, an edge thread clamp for clamping the weft thread and - on the bowl one Cutting device for cutting the weft thread. Furthermore, a groin laying needle belongs to each edge ridge laying device 16, through which the free weft thread end into the following

* Compartment inserted and thus a bar is formed on the edge of the fabric.

The four-shot mechanism 86 includes two further below ι described in more detail up and down movable Hubplatinen 91,92 (Flg. 3), the pivotable at 93 about a fixed axis 25 Angle levers 28,29 are articulated. On the other hand, the angle levers are articulated at 94 with shift force storage devices 30,31 connected, which are described in more detail below. The memory 30,31 contain springs, under the action of which bolts 32,33

. . 209817/0183

are slidable. The bolts are on arms 95 of three-armed Articulated side levers 36, 37, which are rotatable about fixed axes 34. Arms 3B, 39 of the side levers are by means of pins 40, 41 each with one end 42, 43 of a balance lever 35 articulated. A link 45 engages at a pivot point 44 of the balance lever at. On the other hand, the handlebar 45 is hinged to a Kubelarra 46, which can be pivoted about a fixed axis 47. An exchangeable drum 21 is attached to it.

In Nu / th 48a to 48 d of the alternating drum _r are four thread. * feeder 49a to 49d can be moved. They are optionally pushed by a device (not shown) towards the shooter 12 when they are brought into the line of fire.

The drum 21 includes four rear cuts 52a to 52d for a locking roller 53 mounted on a lever 54. The lever 54 can be pivoted about a stationary axis 55. To him a rod 56 is articulated. A pin 57 mounted on the rod 56 engages in a control groove 58 of a groove washer 59, which is attached to a. shaft 61, which with a rotating ' number is the same as the number of wefts driven by the loom. ™

The two energy stores 30,31 are designed the same; Memory 31 is described in more detail below with reference to FIGS. 4, 5. A compression spring 67 is supported in a cylindrical housing 65 between two displaceable spring plates 68, 69 through which a spring bolt 33 is guided. While the spring housing 65 is articulated with an eye 64 at 94 on the angle lever 29, the bolt 33 is with its eye 71 hinged to the side lever 37. The bolt 33 can be in a

209817/0183

Bore 75 of the housing 65 slide back and forth. The bolt has two collars 73,72, which can stand on the spring plates 68,69. The spring plates are in two parts so that they can open the thinner part 33a of the bolt can be set. The spring plate parts are held together from the outside by the spring 67.

In the pulled-out position according to FIG. 4, the bolt 33 is pulled out downwards relative to the housing 65, so that the The spring 67 is compressed downward by the spring plate 68 while the spring plate 68 is lifted off the upper part 65a of the housing is and between the upper part 65a and the collar 73 or spring plate 68 on the one hand and zx ^ ischen the spring plate and the collar 72, on the other hand, an equally large distance S is created. Spring 67 seeks to move the bolt 33 relative to the Housing 65 to move until the distance S disappears. For example, the bolt 33 can be moved up or down by the spring in FIG the housing 65 downwards or both parts 33, 65 can be guided against one another. When S = O, is the energy store 31 in a central, ineffective position.

In the indented position according to FIG. 5, the bolt 33 is shifted upwards relative to the housing 65, so that there is now an equally large distance S ^{1 between spring plate 69 or collar 72 and lower part 65b of the housing on the one hand and between collar 73 and spring plate on the other} arises. If necessary, S ^f = S. In the position according to FIG

817/0183 -9-

The spring strives to move the bolt 33 in the opposite direction as in FIG. 4 relative to the housing 65 up to the ineffective middle position, that is to say, for example, the bolt 33 in FIG. at the bottom or the housing 65 at the top, or both parts 33, 65 can be guided against one another. In the ineffective center position S ¹ = 0. The switching power storage 30,31 can therefore by pulling its two ends 64,71, or by squeezing, respectively are guided from their inefficient center position (^ in a storage position in which they strive ä are, again the to establish ineffective middle position.

Damping pistons 78, 79, which can be displaced in cylinders 80, 81, are articulated on arms 76, 77 of the side levers 36, 37. The cylinders contain damping fluid, e.g. oil. During the downward or upward gear, the piston 78.79 is driven by this the speed of the pivoting movement of the side levers 36, 37 and thus also the alternating movement of the drum 21 in particular

■ - i

delayed in the last part of the movement. Through the lower or upper bottom of the cylinder 80, 81 stops for the piston f 78.79 formed.

Corresponding to the switching movement through the energy storage device 30,31 and the other parts described in more detail below as well corresponding to the upper or lower position of each piston 78, 79, the two side levers 36, 37 can each have two positions take in. Since the pivot point 44 on the balance lever 35 is at a distance of 1: 2 from its ends 42, 43, how

-10-209817 / 0183

is illustrated in Fig, S, four positions 35a to 35d of the balance lever 35 are generated. Each have two neighboring ones Positions a to d of the hinge point 44 are the same distance from each other. In Fig. 6 is for each position a to d ■ of the pivot point 44, the corresponding position 21a to 21d of the interchangeable drum 21 is shown, for the sake of clarity these positions are shown shifted to the right.

In Fig. 3, both pistons 78,79 are in their upper

™ position, memory 30 is in the impression position accordingly ™ Fig. 5 and therefore strives to move the side lever 36 as far as possible to pivot clockwise, memory 31 is in the pulled-out position according to FIG. 4 and thus strives to the To pivot side lever 37 as far as possible counterclockwise. The pins 40, 41 are both in lowest position, so that the balance lever 35 occupies the position 35d and the drum 21 occupies the position 21d on the left in FIG. 6. The thread feeder 49d is in the line of fire. Through the ■ Lock roller 53, the change drum 21 is locked in the incision 52d ™.

The two lifting plates 91, 92 are designed the same and their drive parts are also the same. The lift board 91 and the associated drive parts are described in more detail below. The board has a cutout 101, which is made up of four, for example, approximately vertical sections 101a to 101d is limited. Between the sections 101a and 101b is an arcuate section 101 and between the sections 101c

2098.1 7/61 83 - * ¹¹ -

and lOld an arcuate section lOlf is arranged.

Through the cutouts 101 of the two circuit boards 91,92 two lifting knives 102,103 aind total out. They are fastened in arms 104,105 of two two-armed levers 104,107 * 105,108 which can be pivoted about a stationary axis 106. Drive levers 109, 111, which are driven by eccentrics 113, 114 attached to a stationary shaft 112, engage the arms 107, 108. The shaft 112 rotates at the same speed as the main shaft of the weaving machine, so that each lifting knife 102, 103 carries out an upward and downward movement according to the arrows 115 'per work cycle and thus per weft insertion. Both bib knives have the same stroke. However, the range of motion of lifting knife 102 is "somewhat" higher than that of lifting knife 103. Either lifting knife 102 can be placed in section 10Ie ₁ as shown in FIG. 7 or Kubmesser 103 in section 10lf, as shown in FIG. intervene, depending on the position of the base plate 91 to be described further below. The plate 91 is moved downwards by the lifting knife 102 and upwards by the lifting knife 103. .

At the in Flg. 7 at the upper end of each lifting plate 91, 92, the bolt 33 is designated as a whole by 115 at 116 Control movement force accumulator articulated. Any control store 115 has the same design as the two switching memories 30, 31 according to FIGS. 3 to 5, only with the difference that that on the middle part of the housing 65 of the control memory

209817/0183 -12-

115 with the interposition of a needle bearing 117 (Fig. 8) of the an arm 118 of a three-armed control lever 118, 121, 122 which can be pivoted about a stationary axis 119 is articulated. Furthermore, the control memory 11.5 with a significantly weak ' cheren spring 67 equipped as the switch memory 30,31. A bolt 124 engages the arm 121 at 123, on which a Spring plate 125 is attached. Between this and a fixed part 126 of the loom frame is a pressure ^ spring 127 trimmed. Part 126 carries a guide 128 for

the spring 127. This is. endeavors to pivot the control lever 118,121,122 in Fig. 7 counterclockwise. To the relatively long arm 122 is a harness cord 85 hooked, through which the control lever 118,121,122 when pulling through the Jacquard machine 20 can be pivoted clockwise by 119.

Each Hubplatine 91,92 (Fig. 7,9) has a lower m extension 131, which is limited by curved edges 132,133 Wk . In a stationary part 134 (FIG. 9) of the machine frame, a bush 135 is attached, in which a bolt is displaceably guided. The bolt has a front locking pin 137 on the left in FIG. 9. At the right end, the bushing 135 is provided with slots 138 in which a flange 141 connected to the bolt 136 by a screw connection 139 is arranged displaceably. The flange carries a roller 143 cooperating with a cam 142.

The mode of action is as follows. When the main shaft ζ, Β, especially at 0 °, the harness cords 26,85 according to the diagram A in an intermediate position J (closed shed), lifting knives 102 are leading by pivoting of lever 28 counterclockwise and ran down the shift memory 30 in the pull-out (Fig. 4) from a downward movement in area K according to diagram B, lifting knife 103 an upward movement in area L in diagram C. The lifting plate 91 is held in engagement with the lifting knife 102 at M in diagram E according to the position according to FIG. 7 and is thus moved downwards by the lifting knife at N according to diagram D. FIG. The rubbing knife 103 has no effect on the plate 91, but can, if necessary, be in engagement with the plate 92 so that the latter is moved upward by the rubbing knife 103. The locking pin 137 is located at P according to diagram F in the locking position 137a, as is the locking roller 53 at Q according to diagram G. The changing drum 21 is, for example, at R according to diagram H in the locked position 21d according to FIG. 3,6.

With the further upward movement of the harness cord 85 belonging to the plate 91, the control lever 118, 121, 122 in the area S according to diagram A is pivoted clockwise by 119, the force of the spring 127 having to be overcome and the housing 65 of the control store 115 is moved to the right, so that the control store is out of the neutral center position

209817/0183 " ¹⁵ ""

is transferred into the impression position (Fig. 5). The pivoting the board 91 at 93 clockwise is thus prepared.

At about 50 °, at T, the movement of the locking pin 137 from the locking position 137a into the inoperative position begins (U, at 90 °), If the lifting knife 102 in the shown in Fig. 7, lowest position at 70 ° (V in diagram B) and the lifting knife 103 is in its uppermost position, is the locking roller at W (diagram G) temporarily in ineffective position. Here- ' * through can through the downward movement of the hub plate 91 over the parts 28,94 come about force storage in the switching " memory 30 come into effect. The change drum 21 jumps at X according to diagram H from position 21d e.g. into position 21a. Then the locking roller 53 according to diagram G brought back into locking position. At 105, for example, the 'Shot entry. The storage in memory described above however, it is only used for the next but one weft insertion. _

If the lifting knife 102 in the area Y according to diagram B again j is moved upwards, the Kub plate 91 still follows under the action of a remaining spring tension in the area Z according to diagram D. up to a neutral center position (at g, 125 ° in diagram D) of memory 30. With the further upward movement of the lifting knife 102, this lifts out of the arched section, so that lifting plate 91 in area h (diagram E) under the effect of Control memory force in memory 115 pivoted by 93 clockwise can be. A first stage of the pivoting movement

(k area, chart E) 103 only upon further downward path of the lifting blade passes the lifting blade 103 in the area ■ 'below the arc LOLF so that the Hubplatine 91 by the control store 115 in a second pivoting stage 93 pivots clockwise and get to point m in diagram E. The position according to FIG. 11 is now reached, in which the lifting knife 103 has reached its lowest position 103a, and the lifting knife 102 has reached its highest position I02a. For comparison, these two extreme positions are shown in dashed lines in FIG. 7. At about 230 ° (point η in diagram F) the movement of the locking pin 137 begins from the inoperative position to the locking position 137a (at 270 °, point p). The lifting plate 91 is thus fixed against pivoting through 93 in the new position according to FIG. 11.

The lifting knife 102 thereby reaches its uppermost position 102a at q in diagram B, the stroke knife 103 the lowest position 103a at r in diagram C. Then move first the lifting knife 102 has no effect in the range from s (diagram B) downwards and the lifting knife 103 in the area t (diagram C) upwards. Kesser 103 hits arc lOlf at point u (diagram D). If necessary, the knife 102 can hit the arc lOle at the same time in the case of the blank 92. As a result, the lifting plate is in the area ν 91 moves upwards, so that at 70 ° in point w (diagram C) and y (diagram D) the switching memory 30 is in the opposite extreme position

As soon as the locking pin 137 is unlocked at 153 (diagram F), the cubic plate 91 is pivoted counterclockwise in two stages by 93 in the area 154 (diagram E) under the action of the control memory 115. In this position, the plate 91 | can be taken along again by the lifting knife by engaging in the bow lOle. The switch memory 30 is blocked again and the exchangeable drum 21 jumps after being released by the. Lock roller 53 in a new position.
