    The braking system for the textile machine is provided with a multiplicity of brake elements which are individually controlled via a common control means. Each brake has a different braking characteristic from the other so that the machine components or attachments can be separately braked. The braking system can be electronically controlled so as to not only brake but also to permit adjustment of the brakes.

Weaving machine 1 (Fig. 1 / has a 2 front panel mounted between side posts 3 and 4 machine bed, tension roller 5, and also feed roller B. The latter is driven through shaft 7 with a worm gear 8 and through feed roller 9 with a screw 10 and sprockets 11 and 12, with sprocket 11 through chain 13 and sprocket 14 is associated with a transverse shaft 15 having a sleeve 16, fur Search 17, which, for its part, is connected through bevel gears 18 and 19 to the main shaft 20 connected to the batten drives 21 and 22. The main shaft 20 is connected, on one side, to the auxiliary shaft 23 the wheels 24 and 25, which connects the weft gasket 26 to the receiving box 27, and on the other hand, via the coupling 26 of the main shaft of the machine, shaft 29, pulley 30, belt 31, and pulley 32 to the main drive 33. Shaft 29 has a handwheel 34. On the main shaft 20 there is a (schematically shown) brake 35 with brake brake rabanom36 and brake pad 37, brake 35 via the actuator 38 is connected to the frame via the actuator control 39, clutch 28 via a wire 40 is connected to the frame control 41. The latter is connected by wire 42 to an actuator 43, a control brake 44, mounted on the shedding mechanism 45, which has a brake drum 46 and a brake shoe 47.
    The yawning mechanism 45 drives from the feed shaft 9 through the chain 48 and the sprocket 49. Remizki, controlled by the shed forming mechanism 45, are marked 50. For example, pneumatic or hydraulic cylinders, electromagnets, springs and etc. By wire, 51 stations 41 are connected to sensors that monitor the operation of the machine.
    The loom 52 (Fig. 2) differs from the loom 1 (Fig. 1) only in that it has an elongated main shaft 53 that passes through the stand of the bed 3, rests on the bearing 54, and on which an additional brake 55 with a brake drum is mounted 56 and a brake pad 57. The brake 55 is actuated by an actuator 58, which is connected to control station 41 via wires 59 and 42.
    The loom 60 (Fig. 3) corresponds mainly to the weaving machine 1 (Fig. 1), but additionally has a jacquard machine 61 mounted on a bearing support 62, which drives the (auxiliary) shaft 63 through the auxiliary clutch 64 of your machine and a connecting shaft 65 supported by a bearing stand 66, as well as a sprocket 67, a chain 68. and a sprocket 69 are connected to the shaft 29 of the coupling 28. In this case, a brake 70 is provided with a brake drum 71 and a brake pad 72 on the drive shaft 63.
    Brake 70 through actuator 73 is connected to control station 41 by drive 74. Coupling 64 is connected to station 41 by wire 75. From the jacquard machine, the plugs are passed through a dividing board 76. The finished product (fabric) is wound on the product roller 78.
    The knitting machine 79 (FIG. 4) has a base 82 installed between the side posts 80 and 81 of the machine bed, from which the warp 83 goes to the mechanism 84 of the surf. The finished product (fabric) 85 is wound on a product roller 86. The main drive associated with the main shaft 87. 88
    drives the belt pulley 89, the belt 90 and the pulley 71 to the pattern forming mechanism 92, from which the thread guides 93 come from for the ground threads passing across the threads of the base 83. Next, the main shaft through the pulley 94, the belt 95 and the pulley 96 drives the main pattern 97, from which are thread guides 98 for the threads of the pattern and soil threads, also passing across the warp threads 83. The thread guides of the fine-grain unit (combs and thread guides 98 of the main pattern assembly) are fixed by springs 99 and, accordingly, springs 100
    5 to the holder 101. The main shaft has a brake 102 with a brake drum 103. And a brake shoe 104, which is controlled by an actuating element 105, connected to station 41
    Control Q via wire 106. On the other hand, the main shaft has a second brake 107 with brake drum 108 and brake shoe 109. The brake is controlled by the actuator mechanism 110, which is connected to station 41 by control of wire 111.
    An example of the braking device is schematically shown in FIG. 5, where rotating disks 112 and 113 are used as a sensor of the current (angular) position of shafts 20 and 63 with reading elements 114 and 115 which are connected to station 41 via wires 116 and 117.
    5 controls The read elements 114 and 115 can be made in the form of contactless magnetic switches.
    The disks 112 and 113 may have slots 118-123, which, when passing the reading elements 114 and 115, provide information, such as a photoelectric method, about the position of the shafts. 20 and 63. Position 124 to 5 provided a wire connecting control station 41 to coupling 64.
    Another exemplary braking arrangement is shown in FIG. 6. On shafts 20 and 63, the EE-: s current position sensors are encoded disks 125 and 126, which rotate with the shafts. They have, for example, located on circles with different radii, opaque arcs, shown by solid lines 127 (Fig. 6a), and translucent arcs, shown by dotted lines 128. The position of the shafts is determined using two or more photodiodes 129. Sensor outputs
    The current position of the shafts are the reading elements 130 and 131. With one complete rotation of the control station's shaft 41 containing the decoding unit 132, various combinations of commands can be transmitted
    Slingals) by wire 116 and 117, made as multi-wire lines. With the help of sensors of the current position of the shafts, which act as encoders, in the decoding unit 132 there is information about the actual angular position of the shafts 20 and 63 and this data can be caused by the operator. If the current angular position on one of the disks 125 -k 126 coincides with the angular position embedded in the memory of the control station 41, then a command signal for decelerating the shafts can be selected. The control wire 133 connects the control station 41 to the control device 134, which records the state of the couplings, 28 and 64.
    An exemplary embodiment of the actuator 73 is shown in FIG. 6, b c. It comprises a pneumatic cylinder 135 with an inlet 136 and an outlet 137. Air is supplied to the pneumatic cylinder by means of an electromagnetic valve 138, controlled via wire 74 by control station 41.
    A block diagram of brake control is shown in FIG. -7. . Clutches 23 and 64 are connected via wires 139 and 140 to switch 141, and comparator block 142 via wires 143 and 144 is connected to sensors 125 and 130 or 126 and 131 of the current shaft position. Brake 35, through control wires 145 or 146 and brake 70, is connected via appropriate wires 147 and 148 to computing unit 149, which is connected by wires 150; 151 and 143 with shafts 125 and 130 of the current position of the shafts and wires 152 and 144 with sensors 126 and 131 of the current shafts and wire 179 with the switch 141. Next, the computing unit 149 is connected by wires 153-155 to the selector 156 to brake the 35 loom and wire 157-159 with selector 160.
    The turn-off selectors are connected by control and signal lines to tenological sensors 161 and 162 of machine malfunction. Through a multi-wire line 163, sensors 161 and 162 are connected to a block 164 of predetermined shaft positions, which is connected via wire 165 to computing unit 149. The braking intensity controllers 166 and 167, controlled by brakes 35 and 70, are connected by wires 1b8-171 block 172 automatic tuning brakes. The latter by wires 151, 143 and 17.3, 144 is connected with sensors 125 and 130 of the current shaft position or 126 and 131, and by wires 174 and 175 is connected with a computing unit 149. A braking path adjuster 176 is connected to block 172 of an automatic brake adjustment unit by wires 177 and 178. Position 179 shows the relationship of the computing block; ka 149 with a switch 141.
    Brake devices operate as follows.
    The impulse arriving at the control station 41, for example from one of the electronic or mechanical control bodies of the machine, acts through the wire 40 to disengage the clutch 28 and through two wires 39 and 4.2 to control the actuators 38 and 43, including the brakes 35 and 44. As a result, a simultaneous braking of the main shaft 20 and the shedding mechanism 45 occurs. The control mechanism 17 of the search time, the coupling 16 of the MOFChT will now be uncoupled, and the transverse shaft 15 can be rotated back by one weft to eliminate the breakage hydrochloric yarn prokidyval mechanism 26.
    If the machine has this main shaft 53 (Fig. 2}, then it is equipped with an additional brake 55, also controlled by control station 41.
    When controlling the jacquard machine 61 (Fig. 3), a coupling 64 is used that is controlled from the control station 41. When the coupling 64 is turned on, the main drive 3-3 opens from the jacquard machine 61.
    When controlling the knitting machine (Fig. 4), a second TO rod 107 is used, braking the main shaft 87 of the machine. The presence of brakes 102 and 107 allows for more uniform braking of the main shaft 87 of the knitting machine.
    Let us consider in more detail the operation of the braking device (Figs. 5-7 /. If both clutches 28 and 64 are engaged and the sensors 125 and 130 or 126 of the current shaft position give the same control stations 41 the same values, then the shafts 20 and 63 are in the same angular position and rotate synchronously.If one of the wires 51 commands the braking signal, then the clutches 28 and 64 are disengaged, and the shafts 20 and 63 are decelerated according to a given angular value of the angular position. with next m starting the machine or the machine are taken into account, the lagging of the shaft coupling is engaged first. If both yes h "PRESENT shaft positions produce the same signals as the second clutch is engaged simultaneously with the first and both shafts rotate again
    synchronously. Depending on the type of control signal in the control station 41, various angular stopping distances can be stored in the memory, for example, to stop the machine quickly or slowly. At the same time, depending on the control signal, each brake can be braked with a different force when braking. If the specified stopping distance is exceeded for any reason, for example due to wear of the brake shims, then the slots 118-120 or 121-123 on the discs 112 and 113 can be shifted by the operator. They are set with an angular shift of ot and 2 or ft and (one from the other.
    If it is required that the braking distance fb + (f of the drive shaft 63 of the jacquard machine is 60 and the braking distance is about + at the main shaft 20 of the DZ, then the slots 118-123 are set so that, for example, the angles ft and (f) are more angles than and f,
    In this case, the tormoise 70 must therefore slow down more weakly than the brake 35. When the station 41 receives the corresponding signal for braking on one of the wires 51, both reading elements 114 and 115 are activated. As soon as the slots 118 and 121 are opposite to the reading elements 114 and 115, then the control wires 40 and 124 are disengaged from the sleeves 28 and 64. The shafts 20 and 63 are now turning idling to the angular path cf or ft. As soon as the slots 119 and 122 coincide with the reading elements 114 and 115, then actuating mechanisms 38 and 73 are activated by wires 39 and 74 and with them the brakes 35 and 70.
    Monitoring device 134 receives the appropriate signal and reports, for example using an optical pointer, that the brake needs to be adjusted.
    When a brake device consisting of one, two or many brakes is in operation, it is advisable to combine the current control of the braking tracks with automatic adjustment or regulation of the brakes. At the same time, various different required angular braking paths can be programmed and, when operating, are subjected to current comparison with actually obtained angular braking paths, and the resulting discrepancy affects the brake adjuster. In the braking process, the desired final angular positions of the shafts are also taken into account, depending on whether the cause or the control signal causes the braking itself,
    since it is often not at all indifferent at what angular position, for example in the region of 360 °, the shaft stops completely. In this case, various final angular positions of the shafts can be programmed and, during operation, are compared with the current positions of the shafts and shafts. For example, if a command to brake is received, depending on the magnitude of the difference between the current value of the angular position of the shaft at the moment and the programmed desired value at the end of braking, slow (smooth) or fast braking can be performed. ,
    Suppose that both shafts 29 and 65 rotate synchro. The synchronism of rotation of the shafts can be broken | And the sensors 161 command the selector 156, the selector 156 using the data programmed in it decides which signal should be transmitted further to the computing unit 149: either a fast brake signal through the wire 154, or a smooth braking on the wire 155 Moreover, in case of fast or slow braking of one shaft, the second shaft should always not be subjected to smooth braking. In case smooth braking is sufficient, computing unit 149 receives the appropriate signal through wire 155 along with a control signal through wire 153, which indicates that the soft braking signal comes from sensors 161 and 162,
    Before the computation unit 146 transmits commands for tripping and braking, the signal of the current angular position of the shaft from the sensors 125 and 13 received by wires 143, 151 and 15 is received in its memory.
    As a result of comparing the signals received in the memory of block 149 and the signals caused from block 164 of predetermined shaft positions, block 149 extends the signal to switch 141, which includes wires 28 and 64 through wires 139 and 140, providing shaft disconnection. A signal is then given to the brakes 35 and 70, which both make the shaft stop in a predetermined position.
    After both the shafts are fully braked, the automatic brake adjustment unit 172 compares the current angular positions of the shafts transmitted over the wires 151 or 173 with the angular position stored in the memory. The angular differential corresponding to the angular stopping distance is compared with the corresponding values embedded in the memory of the braking path setter 176.
    If this comparison results in a discrepancy, such as exceeding the specified values of the braking path, then one of the wires 168-171 from block 172 receives a signal to one or both of the braking intensity regulators 166 and 167. The corresponding brake is then automatically adjusted in such a way that the next braking process maintains the specified stopping distance.
    The economic effect of using the proposed device is determined by high reliability in operation.
