    The brake uses a slow brake feature whereby a positioning member, such as a lever, is actuated directly via a first spring to cause braking in response to faults only on the weaving side as well as a fast or normal brake feature whereby the positioning member is able to transmit the braking force of a second spring to effect braking in response to faults on the weaving side or mechanical side. The second spring acts on the positioning member via an abutment which is moved against the positioning member upon release of the second spring. The second spring can be released via an electromagnet in response to a weaving fault on the weaving side or by a stop-motion rod in response to a mechanical fault.

    专利说明:

    This invention relates to a textile machinery industry, namely to a braking device of a weaving machine.
    The closest to the technical essence and the achieved result is the weaving machine braking device, which contains a brake mounted on the main shaft of the machine and connected to a single-arm lever, mainly spring-loaded brake lever, kinematically connected to the shafts of two machine control devices. This braking device has This is a combination of two links and associated with a smart lever. In this case, the first link is connected on the one hand with the first compression spring, and on the other.: The side through the clip with the second pressure spring and the coupling with the BToptJM link. The second link is in conjunction with the stopping shaft and the switching lever. When disconnecting from a gank by means of a stopping second link, it is switched off and both pressure springs act on the brake. When only the deactivating lever is disengaged, only the first pressure spring acts on the brake, and the second pressure spring remains in the compressed state and moves together with thrust 1.
    A disadvantage of the known device is that the second pressure spring in the compressed state and the clamp must be in motion with the thrust. Thus, many mechanical parts and large masses are unnecessarily in motion. In the case of braking through the stopping shaft, relatively large masses must also move together, since the link with the clutch and the clamp connected to the first pressure spring must move along with the thrust. In this way, the device does not work out quite clearly after a signal is applied for braking due to the inertia of the parts, which requires the installation of springs with a more powerful effect, and therefore reduces the service life of the brake device.
    The purpose of the invention is to increase the service life.
    This goal is achieved in that the braking device of the weaving machine, which contains a brake mounted on the main shaft of the machine and connected to a single-arm, mainly spring-loaded brake gear, kinematically connected to the shafts of two control devices of the machine, the kinematic linkage of the single-arm motor lever and the shaft of the first the control unit of the rotary instrument has a locking latch fixed on the shaft, and a two-arm lockbar, one of which 40 is kinematically connected with the one-arm brake lever and the other in contact with a locking latch, and the kinematic connection of the single-arm brake lever and the shaft of the second control device has a spring-loaded lever mounted on the axis of the single-arm brake lever with its stop positioned so that its longitudinal axis is in a plane perpendicular to the plane of the lever with the stop, and retractable with the possibility of interaction with the stop with a single-arm brake lever, a locking latch fixed on the shaft of the second control lever, and a two-armed lock lever one shoulder of which is kinematic and connected with a single-arm lever, carrying the stop, and the other in contact with the locking latch, while the locking latch of the second shaft of the control device has a stop positioned so that its longitudinal axis is located in the plane perpendicular to the swing plane of the locking latch and installed with the ability to interact with the locking latch shaft of the first control device.
    The drawing shows the proposed brake device.
    On the main shaft 3 mounted in brackets 1 and 2, the brake disc is fixed. 4, covered by a brake tape 5. One end of the brake tape 5 is fixed on the axis 6, mounted console in the support 7. The other end of the tape 5 in the form of a loop 8 is connected to the brake lever 10 mounted rotatably on the axis 6 through the cable 9. This lever has a trunnion 11, which serves to secure the first generator 12 braking forces, mounted on a spring console 13 and made in the form of a tension spring, as well as a hinge connection with a pull 14, which is connected to a stop lever 15 pivotally mounted on a cantilever axis 16 . WITH the clutch lever 15 is in contact with a locking latch 17, which is attached to the shaft 18 of the first control device mounted in a cantilever support 19, with the shaft 18 is rigidly connected the lever 20 connected by means of a flat spring 21 to the retracting magnet 22, This part of the braking device can function autonomously and is a soft stop circuit. On the axis 6, the lever 23 is mounted with the possibility of rotation with an emphasis 24 for contact with the lever 10. The lever 23 is connected with a brake console 13, using a pull-rod 26, to the cTonopHtM lever 27, installed on the cantilever axis 16. The latter is in contact with the stop.; a latch 28 having an abutment 29 for contacting with the locking latch 17. The locking latch 28 is fixed on the shaft 30 of the second control device. Shaft 30 is mounted in cantilevers in supports 31 and 32. Lever 33 is fixed on shaft 30 and connected by means of a flat spring 34 to a retractor 35. An additional shaft 36 is installed in supports 37 and 38 and has a lever on the console. and between the supports is a lever 41, with a pull 42. The lever 39 contacts the end of a corner lever 43 fixed on the shaft 30 .. The described other part of the devices only works together with a soft stop circuit, which is acceleration to stop loop. The braking device works in the following way .. Since the accelerating stop circuit should be used mainly only for the causes of malfunctions due to technological factors, it is assumed that the pull-in magnet 22 is connected through signal wires (not shown) with electric primary observer or electronic weaver controller. Signals of electronically DO weft self-stopping can be applied to the pull-in magnet 22 to a predetermined degree position of the main shaft of the weaving machine. If a corresponding signal is applied to the pull-in magnet 22, the flat spring 21 moves in the direction of the arrow of the drawing, turns the lever 20 and, accordingly, the shaft 18 in the direction of the arrow. In this case, the locking latch 17 rotates upwards, releases the locking lever 15., which under the influence of the tension spring 12 and the rods 14 rotates in the clockwise direction, and the lever 10 rotates against the direction of the clockwise movement, after which the brake tape 5 presses against the brake disk 4. In this case, the spring 12 can be calculated relatively weakly, with the result that smooth braking is achieved with a relatively long stopping distance. To describe the operation of the accelerator stop, the pre-LINK circuit, is that the pull-in magnet 35 is also connected to the electronic self-stopping unit, but you can connect leaks to the pull-in magnet 35 to indicate a malfunction starting at a certain degree of the main shaft. The connectors 40 or 42 of the shaft 36 may be connected to mechanical safety bodies, for example, to an observer for catching the weft yarn, etc. If, for example, the pull-in magnet 35 receives a corresponding signal from the weft controller, the flat spring 34 will move in the direction of the drawing arrow and the lever 33 will turn the shaft 30 in the direction of the arrow. The locking latch 28 rotates in the clockwise direction, not only does the locking lever 27 release, but also through the stopper 29, the locking latch 17 rotates in the clockwise direction, and accordingly, the locking lever 15 is released. Thus, both locking levers 27 and 15, and also the levers 10 and 23 rotate in the clockwise direction under the influence of tension springs 12 and 25. Through the stop 24, the lever 23 transmits the tension of the tension spring 25 to the lever 10 so that both tension springs 12 or 25 together act through t gu 9 per t The brake belt 5. In this case, the tension of the tension spring 25 may be significantly greater than the force of the spring 12, which results in a quick or normal weaving stitch. - If, for example, one of the tg 40 or 42 of the shaft 36 of the stop acts in the direction of the arrow on the end of the lever 36 or 41, causing that stop of the shaft 36 to stop in the direction of the arrow, through the lever 36 by acting on the end of the angular lever 43, the shaft 30 turns and then the described process of quick stop of the machine is repeated. In this case, the flat springs 14 and 24 bend and allow the levers 20 and 33 to turn. As the generators 12 or 25 of the braking forces, you can also use pull-in magnets or pneumatic cylinders and the like. A single lever 10 can also be designed as an axially guided element, which is under the influence of the anvil 24 of the lever 23.
