Description

The invention relates to improvements in

ν Devices for shedding by means of selected Cams in looms with slidable harnesses or shafts. Generally speaking, the invention has the aim is to create a simple cam or cam arrangement, the cams of which are selected individually can to move the shafts so that the warp threads form so-called sheds or openings between them. Through this shed a loom is driven through during each work cycle of the loom, around one To lay weft.

At indicated, widespread types of looms with cam arrangements for shedding by raising and lowering the shafts, a set of curves works in one fixed circuit in such a way that the shafts are periodically raised and lowered during each circuit Need to become. Because of this periodic raising and lowering, one equipped with such a set of cams can be used Loom only a specific or limited pattern can be created. If it is desired to change the pattern, it must

the set of pins used can be replaced by another one that is of the desired pattern of the corresponding shape. If, for example, a loom with a curve arrangement for shedding is based on a l / l simple pattern a 1/3 twill pattern is to be converted, then the set of cams for the single pattern must be exchanged for a set of cams, which leads to the desired twill pattern. Because of the need to exchange sets of cams for the purpose of achieving different patterns is the variability of one such Loom, at least as far as the pattern formation is concerned, to the number of sets of cams delivered with the loom limited. In addition, it is very expensive to use looms to enlarge the pattern selection with different sets of cams to equip, and the change from one set of cams to another is very expensive because of the set-up time required. This is all the more true as the resulting downtime of the machine also results in production downtimes result. For this reason, an important aim of the invention is to extend the interchangeability of patterns Looms of the above type significantly reduce or even avoid the limitations and costs that come with them the above statements have occurred so far. The stated aim is to be achieved in that the looms be equipped with a device for shedding by means of selected cams, in which the actuation of the shafts does not need to take place in a fixed cycle and in which it is not necessary for the pattern change, Exchange sets of cams for others.

According to another object of the invention, the device for shedding by means of selected Ifocken with in the longitudinal direction slidable squat members for each shaft be equipped, the opposite longitudinal displacements of your choice can perform to raise or lower the shafts or the shafts for, depending on the direction of movement of the squat any number of work cycles of the loom either in the raised or lowered position.

Another object of the invention relates to a device for shedding by means of selected crouching with several pairs of actuators, each pair being interconnected to move simultaneously in opposite directions, namely first in one sighting towards one another and then in the other direction away from one another. Pabei should caused the Vtrschiebungsbewegung the Hock members only on movement in the one of said directions were ·· =: ^1, provided that the relevant I'oc-kengiied has been selected for the Verschiebun ^ sbewegung. Another object of the invention is to associate a selector with each of the slidable cam members, which is monitored by one of the patterning device and is normally not influenced by the actuators, the patterning device either causing the selector to pivot in opposite directions in one of two working angular positions or the selectors are allowed to stay in one of the two positions. The balancing pieces are separate from the actuating members, but can be connected to these for cooperation when they have been moved into one of the aforementioned angular positions. If that's the tall, do the

opposite movement of the pair of actuators is a shift the selector pieces and the Iockglieder in the same. Direction from one longitudinal position to another longitudinal position and thus leads to a raising or lowering of the associated shafts, depending on the direction in which the cam member moves has been.

Another object of the invention is the device for shedding by means of selected cams with a pair uniformly rotating parts be equipped with associated, trapezoidal curves, each of which has surface parts, which cooperate with the actuators during the initial and final phases of the movement of the actuators to delay this movement. In this way, when the actuators are about to cooperate have been connected to the selection pieces, no impacts are transmitted from the actuators to the selection pieces, and accordingly a sudden stop of the shedding device and the shafts during the final phase of the Movement of the actuators avoided, so that here too the impact loads are considerably reduced.

According to another aim of the invention, the surface parts of the trapezoidal curves used for deceleration should pass through Surface parts are connected, which increase the speed of the actuators between the delay times, " to compensate for the delay and the device for weaving \ • shedding in good timing with the speed of the loom. The greatest speed is reached at the point in time when the shafts one between them cross the upper and lower position. Leading

809805/0667

when they meet in the middle position so that the stapling together of the fibers due to the crossing of various threads speed avoided to a quick snap past each other of warp threads and a proper tray or _v proper opening is formed.

Another aim of the invention is to provide a control device with a compliant connection and an arrangement of multiple selectable rods and levers, wherein for each set of curves that lies between the patterning device and the select pieces and is permanently connected for interaction is, such an arrangement should be provided so that "when one of these arrangements is selected for actuation by the pattern forming device pivots the associated selection pieces at an angle from one position to the other and 'are connected for cooperation with the actuators.

According to a further aim of the invention, each of the selected items should be equipped with a pair of hooks, one of which is on each side of the joints of the selector pieces and associated with working with corresponding parts on each Actuating member pair is used to guide the sliding movement of the associated cam members in the way when one of the Hook has been connected to the associated pair of actuators.

Another object of the invention relates to slidable cam members with locking members at each end, the Locking parts at one end have a dry element with high and have low surface parts with a shoot connection between the surface parts and the shafts and - ',' 809805/0667

the weight of the latter work together to make the stems for to keep any number of work cycles of the loom raised or lowered. Me locking parts on the other end of the sliding IToekenglieder contain locking fingers, the sn the selector pieces are hinged to cooperate with the pawl parts on the actuators and to hold the shafts in place when the hoist is stopped and the shafts are between them upper and lower end positions.

Another object of the invention relates to a Device for the formation of compartments by means of retrievable cams, in which the cams can be adjusted by the adjustment device as required can be called up for a longitudinal displacement movement, whereby the shafts can thereby be actuated during each working cycle of the loom. But the squats should also for any number of loom work cycles can remain in one or the other of the two longitudinal positions in order to move the shafts depending on the longitudinal position which the curls assume, raised or lowered, when the dwell position is called up.

According to a further aim of the invention, a device for multiplexing is to be created which, as a structural unit can easily be attached to the ulmachine and with the largest part of the device in a housing with a lubricating ' device is housed. The only! Parts that are housed outside the housing should be those .which are connected to the stems and patterning device for cooperation.

809805/0667

Another aim of the invention is to use one of the actuators to operate a pump, to effect the lubrication of the various parts of the shedding device in the housing.

Another object of the invention relates to the manufacture and placement of the slidable squat members in that the latter are made up of two parts that are locked together to form a rigid one Link which, on the other hand, can easily be unlocked and separated from each other if that arises from any Reason proves necessary.

It gets special now on Pig. I referenced. the right and left side pieces 1 and 2 of the loom are connected by side members 3, 4 and 5 to form a general as 6 designated rigid framework to form. The framework supports the harnesses or shafts 7, 8, 9 and 10 in the Way that they can be moved vertically independently in right and left guides 13 and 14, respectively. The tours 13 and 14 are carried by guide arms 15 and 16, respectively, which in a suitable manner, for example by means of bolts 17, to the Side pieces 1 and 2 of the loom are attached. One driven by the loom motor not shown in detail Shaft 18 rotates a suitably supported intermediate shaft 19 by means of a bevel gear pair 20 and 21 (FIG. 15) -Kegelrad 20 is on the shaft 18 and the bevel gear 21 on

the intermediate shaft 19 attached. One stuck on the shaft 19 Transport roller 22 transmits a uniform, clockwise rotational movement to a cross shaft 23, as shown in FIGS. 1 and 2 can be seen. The transfer takes place by means of a chain 24 that is around the transport roller 22 and one on the Cross shaft 23 attached transport roller 25 is placed. The cross shaft 23 is rotatably supported in a housing 26. That Housing 26 contains the device for shedding means selected squat, indicated generally by the reference numeral 27 is. On the intermediate shaft 19 sits a second transport roller 28, see Figs. 1 and 15, which meshes with a chain 29, which in turn leads to a transport roller 30 on a shaft 31 and is wrapped around it. The Ί / elle 31 forms one Part of the sample device described below. If in the present Embodiment only four shafts have been shown, so of course the invention is not limited to that. Rather, more or fewer shafts can be used and the device for shedding be actuated by means of selected cams, as will be discussed in detail below.

Reference is now made to FIGS. 1, 2 and 8. The device 27 for shedding, by means of selected Squat contains a shaft 23, -the several belonging together, trapezoidal curve units with the general reference numerals 32 and 33. The curve units run while you work of the loom uniformly in a clockwise direction (see Figs. 1 and 2), to swing several pairs of actuators back and forth at the same time. Each pair of actuators is with each other connected and generally by the reference numerals 34 and 35

809805/0667

designated. There is a pair of actuators for each cam unit intended. The curve units 32 and 33 are each stretched on individual hats 36 and 37. The curve units match and have front and rear cams 38 and 39, respectively. The cams 38 and 39 have arcuate slots 40 which are offset from one another by certain angles (see FIG. 2) and are located at the same distance from the axis of the shaft 23 · The slots in one of the cam units coincide with the corresponding ones Slots in the other cam unit. Bolts 4, 1 are inserted through the slots to: .the cam units against each other and opposite right and left collar sleeves 42 and 43, respectively (Fig. 8) to secure. The collar sleeves 42 and 43 are secured by wedges at 44 and 45, respectively, on the shaft 23. A Spacer 46 laterally fixes the cam units on shaft 23. The slots and bolts allow adjustment of the cam units in the angular direction against each other in order to be able to vary the time in which the shafts move into each other cross their central position. This will be discussed in more detail below.

The circumferential shape of the cam disk 38 of the unit 32 contains, based on the axis of the shaft 23, ascending surfaces a, b and c and a descending or returning surface r, each between the dashed radial lines A and B, B and 0, 0 and D and D and A in FIG. 17. The cam 39 is of a corresponding, but reversed shape and contains the descent surfaces a ', b ¹ and c ¹ and an ascent or return surface r', each between the dash-dotted radial lines A 'and B', B 'and O ¹ , C. ' ¹ and'

D ¹ , D ¹ and A ^f lie. Each curve unit stands by means of. Rollers 47 and 48 each in operative connection with their actuating member 34. The rollers 47 and 48 are each rotatably mounted on pins 49 and 50 on the actuating members 34. Since the cam unit 34 corresponds to the cam unit 32 in terms of structure and mode of operation and is in the same way as the unit 32 with a pair of actuators in 7 /? to explain in detail. Rather, it seems sufficient to state that each cam unit revolves together to cause its associated actuators to move back and forth so that they move simultaneously.

The actuators 34 are articulated on a connecting piece 51, which is in front and rear bearings 52 and 53 on front and rear supports. 54 or 55 rotatable is stored. The two supports are secured by bolts 56, of which in lig. 2 only one is shown on the housing 26 held. The actuators 34 include a pair of side upstanding arms 57 and 58 and a pair drooping arms 59 and 60. Between the upright arms is the role carried by the pin 50

. member 34 is transferred to the upright arms 47, 48 inwardly towards the center of the loom and in the opposite direction To pivot outwards, lin the third arm

• pair 61 and 62, which also forms part of the actuating members 34, is connected to the actuating members 35 by a connecting member 63 in such a way that when the actuating members 34 move inward, the actuating members go outward and vice versa. The actuators 35 are mounted on a socket 51 'and are similar in construction to the actuators 34 in that they have a pair of upright arms 64 and 65 and a pair of substantially horizontal arms 66' and 67 '. The connecting member 63 is attached to the arms 66 'and 67'. At the upper end of a pin 66 and the arms 64 and 65 extending between the arms 57 and 53 bear laterally a similar pin 67. ^T he pins 66 and 67 ice pawls for cooperation are considered to be described with hooks. The actuating members 34 and 35 are aligned with one another and follow one another in the longitudinal direction, as can be seen in FIGS. 2 and 8. A second rearward pair of actuators are denoted by the same reference numerals 34 and 35 and are constructed similarly to the front actuators 34 and 35. It therefore does not appear necessary to describe the rear actuators 34 and 35 and their mode of operation here, since their construction and their mode of operation are very similar to those of the front actuators 34 and 35. The actuating members normally have a non-working stroke in two directions - towards and away from one another -, but they can also have a working stroke if they only move in one of the aforementioned directions.

The rear and the front pair of actuators can also be arranged on the cross shaft 23 so that the shaft capacity of the loom is increased. A spacer which is larger is then arranged between the front and the rear pair of actuators than the spacer 46 of the Pig. S, the length of the bolts is dimensioned accordingly and there are keyways on the Provided the shaft 23 where the actuators are to be attached. The pins 66 and 67 can easily be extended like this that they extend from the front pair of actuators to the rear pair of actuators, regardless of which shaft absorption is desired.

Especially in the I ¹ Xg. 1 and 2 it can be seen that a plurality of two-part focking members or levers 68, which are normally in the rest state, are mounted so as to be longitudinally displaceable between a support surface 69 and a pair of guide pins 70 and 71 (see Figure 2). The support surface 69 is held on the belts 4 and the guide pins are firmly seated on supports 54 and 55. As shown in FIGS is located, which is movable together with its associated link member 68 when the latter performs its longitudinal movement. -15-

The uniformly rotating cam members 32 and 33 therefore complete one complete revolution for each working cycle of the 7 / eb chair, and during this revolution the actuating members 34 and 35 first move simultaneously in opposite directions towards one another into the position shown in S ¹ IgV-IO and then, in opposite directions away from each other into the position shown in FIG. The movement of the actuators 34 and 35 is a smooth, reciprocating movement; ie that the curves have no rest period. -J · · 80 980-5 / 0667 ■

If the actuators are in the S ¹ Ig. 10, the sample chain levers 107 are either raised or lowered in accordance with the inister chain 104 in order to cause the levers 73 to pivot clockwise or counterclockwise, as can be seen in FIG. Certain levers 107 can also be selected by means of the pattern chain, among other things to remain in the idle state and to maintain the position which they have from their previous setting. This avoids pivoting of the associated levers 73 ″. If the actuating elements move towards one another, they have a work-free stroke and when the actuating elements move away from one another, they either have a working stroke or a non-working stroke, depending on whether a Lever 73 has been pivoted or not In Figure 10, for example, the movement of the actuating members 34 and 35 apart causes levers 73 and the associated shafts to be occupied unless one of the levers 73 is welded that the pattern shaft 31, due to the ratio of the transport rollers 28 and 30, rotates the transport roller 103 for each work cycle of the loom by a sixth of a turn in order to bring a roller or a load piece under the lever 107 and thereby lifting or lifting to effect, depending on what kind of role is under the levers 107. ^T , ¹ / enn die

selected lever 73 either "from left to right or vice versa, depending on which lever has been brought into operative connection with the actuating membersii. The surfaces a and a ¹ leave the actuating members by means of the rollers 47 and 48 initially when the cams 38 and 39 are rotated slowly diverge so that the pins 66 and 67, respectively, receive the holders 135 and 136 softly and easily when the pins move from the position of Fig. 10 to the position of Fig. 11. The surface parts b and b ¹

ensure acceleration as the curve continues to turn the movement of the diverging actuators, so that the actuating elements diverge very quickly and become one rapid displacement of the lever 73 from left to right or reverse effect. YiTenn, the Hollen 4-7 and 48 from the surface parts, c "or-, c * are touched, the actuators are delayed to prevent a sudden stop.

The levers 73 are, as mentioned above, hinged to the U-shaped link members 68 and when these levers 73 are moved in the longitudinal direction, the link members 68 are also displaced in the same direction as the levers 73. Has the result that the IS cam elements 72 move, depending on the selection of the lever 73, to the left or right in order to actuate the connecting parts

For the purpose of ensuring that the levers 73 are not pivoted when the actuating members are in the position shown in FIG lock the raised or lowered position for each selected number of work cycles of the loom. The shafts can be raised or lowered with every working cycle of the chair, or they can remain in the rest position for any length of time, depending on whether the associated levers 73 are pivoted at an angle or not. The pins 66 and 67 normally go on a path IrLn ₄ and forth, where movement of the lever 73 is avoided until the lever has been pivoted from one angular position to the other angular position. When a lever 73 has been pivoted into an angular position by a lever 118, it returns to its original position by means of the spring 128, if the pattern chain determines this by means of a low roller As the actuators 34 'and 35 move forward, the oil pump 176 pumps oil through the conduit 177 so that the oil is expelled from the conduit opening 178. The pumping action is brought about by the arms 61 and 62 and the connecting link 175 when the actuators 34 to the right, move (Fig. 2).

The locking fingers serve to lock the shafts in each of their positions between the upper and the lower position while the loom is stopped, i.e. the loom is stopped while the rollers 86 and 87 are entrained 77 and on the inclined surface 78 of the jib links 72 are located, the weight of the shafts cannot drop into the lower position. The low surface parts 74 and 75 and the high surface part 76 of the liockeneleiuente also act with the rollers 86 vaiö. 87 and the weight of the shafts together to lock the latter in either a high or low position.

The cam disks 38 and 39 are each also provided with return surface parts r and r ¹ , which cause the opposite movement of the actuators for a non-working or return stroke. The surface portions a and a ^r allow the levers 73 to be easily picked up because of the above-mentioned deceleration. The surface parts c and c * lead to the slowing of the movement of the shafts at the end of the raising or lowering movement in order to avoid a sudden stop and thus the transmission of shock loads to the shafts and the Yorrich-.

to avoid professional training! The surface parts b and b ¹ , which are respectively between the surface parts a and c and a 'and c *, accelerate the actuating members so strongly that the shafts cross each other in their jiittei position a at a speed which is greater. than those brought about by the surface parts a and c and a ^f and c ^1. In this way, the shafts cause the warp threads to jump or cross over one another, so that the jades do not stick together. Because of this rapid removal of the chain threads, the result is a perfect compartment opening through which the ship can be driven.

To make it easier for the warp threads to move past one another, can, the qualification of the Eurven units 32 and 33 by means of the slots 40 and bolts 41 set ΐ -rerden, ura a so-called to form split IF'ach.

From the foregoing it follows that the invention provides a simple device, ie raising or lowering the shafts of a "loom" for any work cycle and the shafts for any number of work cycles of the Ti chair raised or lowered. 3s also shows that with the invention a device for '7ebfachbildung by means of selected cams has been created, in which the jib elements are selected by selection pieces under the lauster to be lifted according to the • control' to raise or lower the shafts and to have the latter stranded in a raised or lowered position.

It can also be seen that two-part cam members with locking parts are provided which keep the two parts rigidly connected and allow them to be separated and removed from one another in a simple manner. The present invention also provides fasteners for the shed selector; Most of the gate direction is placed in a housing underneath it, which forms a unit and can be easily and quickly attached to or removed from the loom. The parts in the housing are also lubricated by supplying the latter with a lubricant which is pumped to the various parts through the actuating glides 34. The gate direction for web facix formation by means of selected cams can be used when weaving various types of fabric without any changes in the gate direction. It is only necessary to hang in the correct pattern chain for the desired fabric. When this is done, the cam elements cause the shafts to rise and fall in accordance with the desired pattern. Means are also provided to adjust the angular position of the Tranez-shaped Eurven units in relation to one another, so that a split
