Definitions
- the present invention relates to a device for stopping a rove supply in a spinning or twisting apparatus after the break of a yarn according to the preamble of claim 1.
- the purpose of such stopping devices is to prevent a rove, which is supplied to a drafting zone of such a twisting apparatus, from being continuously delivered even after a yarn break has occurred.
- the stopping device is provided in order to stop a rove before the back rollers of a drafting zone of the spinning apparatus so that the elements of the drafting zone are prevented from damage and that the formation of a lap of fibres of rove material around the rollers is avoided.
- Such yarn breaks are a major problem in spinning machineries. Not only is the continuous operation of the spinning interrupted, but also the total efficiency of the spinning is decreased.
- pneumatic stopping devices have been used in dry spinning devices, with a suction nozzle being arranged close to the yarn so that any fibre, which comes out at the front end of a drafting zone and which is not formed into a yarn, is collected by the suction nozzle.
- Such pneumatic devices with a suction nozzle therefore stop the fibres or material from wrapping around the delivery roller in the drafting zone.
- One disadvantage of such a type of pneumatic stopping device is that the amount of waste material is considerably increased, because the delivery of the rove is not stopped, but the material is only guided to a waste container. For a reintroduction of such waste material, the fibres have to undergo again the preparation processes as known to a person skilled in the art.
- a further disadvantage of such pneumatic devices in dry spinning processes is the increase in energy consumption. The pneumatic device has to be operated at all times and at all spinning positions in the spinning apparatus.
- the clamp device is arranged in a predetermined distance from the entry of the drafting zone, i.e. a distance from the back rollers. Since the clamp device is arranged at the input side in a distance from the drafting zone and not within the drafting zone, the installation of the stopping device does not require any changes in the construction or design of the spinning apparatus. The device may be simply installed without any impact on the normal functioning of the spinning apparatus.
- the sensing lever is repeatedly brought into contact with the yarn such that a yarn break in this critical section is immediately sensed by the sensing lever.
- the frequency of sensing contacts and the pressure of these contacts can be adjusted to suit all yarn counts. Upon yarn break, the sensing lever immediately moves together with the release lever in a pivot movement into such a position that the clamp device at the input end of the drafting zone is directly activated.
- the stopping device according to the invention Since the sensing lever and the release lever activate the preloaded clamp device directly and not by means of several intermediate levers or gears, the stopping device according to the invention is very reliable and not prone to disturbances, e.g. due to dirt or other surrounding influences. Due to the special mechanical design and construction of the stopping device according to the invention, the device does not require any additional energy for its operation. This leads to energy savings in comparison to pneumatic or electronic rove stop systems as they have been used in the prior art.
- the conjoint pivot movement of the sensing lever and the release lever for releasing the preloaded clamp device has the advantage that, after the break of a yarn, the operator of the spinning apparatus receives also a visual indication in a row of a large number of spinning positions in a spinning apparatus.
- the end of the sensing lever with its sensing pin will protrude compared to the other sensing levers in the row of spinning positions so that an immediate visual indicator is given that the operator has to take action and repair the disorder in a specific position. Since the rove is not cut, but is actively clamped through the clamp device, in particular corresponding eccentric clamp elements, the restoration of the correct operation is rather simple to realize.
- the operator does not have to search for the rove end, but can directly take the clamped rove end and reintroduce it into the drafting zone and connect it with the already drafted yarn at the output side.
- the handling of the stopping device is therefore very simple and reliable.
- the mechanical construction and the form of the stopping device according to the invention with a sensing pin and a sensing lever at the output side of the drafting zone and a clamp device at the input side are advantageous in that the stopping device can also be installed in existing spinning apparatuses. No changes have to be made in the drafting zone of the spinning apparatus.
- the stopping device according to the invention can simply be attached to the existing frames or drive shafts of the spirining machinery since it is specifically designed without components inside of the area of the drafting zone.
- the sensing lever and the release lever of the stopping device have an essentially L-shaped integral form and/or the sensing pin is provided as a separate and exchangeable element.
- the L-shape has the advantage that the stopping device may be mounted behind the drafting zone without a change in the construction of the existing spinning apparatus.
- the sensing lever and the release lever are formed in a single-piece element, for example by moulding of a plastic material or the like.
- the single-piece construction of the levers has the advantage that only a reduced number of different elements and moving parts for the device are required.
- the clamp device comprises two opposite counter-acting eccentric clamps, which are pivotally mounted on both sides of the rove such that a pulling force of said yarn by means of the rollers in the drafting zone will automatically increase the clamping effect of said clamp device.
- This measure prevents that the stop of the rove is unintentionally released. A further pull on the rove from the side of the drafting zone will inevitably lead to an increase in the clamping effect.
- the clamping of the rove is therefore not only guaranteed by means of the preloading through a spring or the like, but also through the specific construction and arrangement of the clamp elements of the clamp device. By means of these measures, the reliability of the device is increased.
- the clamp device has a preloading spring for an automatic closing of the clamps upon release through the release part of the release lever/sensing lever.
- the clamp device In the open state, the clamp device is securely held by the release lever against the preloading force of the spring of the clamp device.
- the clamp device After the release part of the release lever has moved in a specific position, the clamp device is automatically activated and will due to the preloading force directly change from its open state into its closed state, in which the rove passing through the gap between the clamp elements of the clamp device is firmly held through a clamp action.
- the provision of a spring for preloading one or both of the clamp elements of the clamp device is a simple and nevertheless very reliable means.
- the preloading spring may be integrated within a clamp element so that the spring, which is normally made of metal, is protected against corrosion due to the sometimes wet environment.
- the sensing lever is pivotally mounted on a common support element with said pivot axis and a rocking cam, which rocking cam is directly or indirectly driven by the back rollers or the shaft of the back rollers of a drafting zone of the spinning apparatus such that the sensing lever is repeatedly moved against said yarn at the output side of the drafting zone.
- the common support element further simplifies the construction and the installation of the stopping device also in existing spinning apparatuses.
- the rocking cam may be installed on the common support element close to, for example, the back rollers of the drafting zone, which may be used for the rotational movement of the rocking cam in such a manner that the cam surface is in contact with an inside surface of the sensing lever and/or activating lever.
- the sensing lever and its sensing pin are repeatedly brought into contact with the yarn in order to mechanically sense whether or not a yarn break has occurred.
- a repeated rocking or forward movement of the levers of the stopping device against the yarn may be realized about 5 times per minute.
- the number of rocking movements and contacts with the yarn may be adjusted. For example, by changing a gear at the driving end of the cam shaft, the sensing contact can be varied from 2 to 6 times per minute.
- the sensing lever and/or the release lever is provided with a leaf spring element on an inside region coming into contact with the rocking cam.
- a leaf spring element in the form of a leaf- spring-type element may be provided as a separate leaf spring installed within a recess in the inner side of the release lever or sensing lever.
- the leaf-spring-type element may be formed in an integral shape with the levers, e.g. by providing a longitudinal slot and a surface with a reduced thickness in the material, in particular plastic material, of the levers.
- Other forms of such a soft leaf-spring-type element may also be provided and are within the knowledge of a person skilled in the art.
- a rocking cam for driving the sensing lever against the yarn and back again is provided with a rocking shaft being synchronized with the rotational speed of rollers of the drafting zone. Due to these measures, the movement of the sensing lever is always automatically adapted to the speed of production of yarn in the drafting zone.
- the rotational speed of the rocking cam shaft is adjustable, so that the device has a further possibility of an additional adjustment of the sensing lever speed.
- the pivot axis of the sensing lever is arranged at a predetermined balanced position such that the sensing pin is repeatedly pushed against the yarn with a predetermined force.
- the balanced mounting of the sensing lever and the release lever has the advantage that no additional preloading elements, such as springs or the like, are necessary in order to realize the predetermined sensing force of the sensing lever.
- the amount of the sensing force of the sensing lever may be in the range of 50-200 g per push action.
- the sensing lever is provided with at least one movable or adjustable balance weight for the adjustment of the specific pressure or force applied by the sensing pin onto the yarn.
- the movable balance weight may, for example, be attached to the levers at a discrete number of positions.
- the clamp device has an activating lever with an engagement portion for engagement with the release part of the release lever, and furthermore has a release lever for returning the clamp device from its closed position back into its open position for the restarting of the operation of the spinning apparatus.
- the provision of an activating lever has the advantage that the release end of the release lever may be located not too close to the rove, but in a certain distance from it.
- the engagement portion of the activating lever of the clamp device is during correct operation of the spinning apparatus in engagement with the release part of the release lever such that the rocking movement of the sensing lever and release lever does not lead to an inadvertent activation of the clamp device.
- the release part is provided in the form of a longitudinal groove at the end of the release lever, which is open to one side.
- the engagement portion of the activating lever of the clamp device may move by a certain predetermined amount without leaving the engagement with the levers. Only in the case of a yarn break, when the sensing lever moves beyond the usual position of the yarn, the groove of the release part is moved to such a position that the engagement portion of the activating lever of the clamp device is released. After release, the clamp device is directly closed through the action of the preloading spring. The engagement portion of the activating lever of the clamp device is then in a position beyond the end of the release lever such that the system is effectively deactivated. Only through the active pulling of the release lever of the clamp device and simultaneously the reintroduction of the engagement portion into the groove of the release lever through an operator, the system is put in its preloaded open position again, in which the normal operation of the spinning can be effected.

- Fig. 2 and 3 side views of an embodiment of the stopping device according to the invention showing different positions of the device in the normal operation of the spinning apparatus; and
- FIG. 4 and 5 side views of an embodiment of the stopping device according to the invention showing different positions after a yarn break has occurred.
- FIGs. 1 to 3 an embodiment of the stopping device according to the invention is shown in a situation of a normal operation of the spinning apparatus, i.e. before a yarn break has occurred.
- the stopping device comprises a mechanical sensing lever 7 being pivotally mounted on a pivot axis X on the back side of a drafting zone A of the spinning apparatus.
- the sensing lever 7 is provided with a laterally protruding sensing pin 8, which is repeatedly brought into contact with the yarn 11 by means of a rocking movement of the sensing lever 7.
- the repeated rocking movement or push of the sensing lever 7 and its sensing pin 8 is indicated by arrow B. The purpose of this repeated contact of the sensing lever 8 and the
- the sensing lever 7 is in contact with a rocking cam 15, which is driven by a shaft 18.
- the rocking cam 15 has a cam surface, which comes into contact with the inside of the sensing lever 7. Since the sensing lever 7 is pivotally mounted on the axis X, the rotational movement of the rocking cam 15 pushes the sensing lever 7 and the sensing pin 8 repeatedly back, so that the sensing pin 8 is moved against the yarn 11 coming out from the drafting zone A.
- the sensing lever 7 which is here formed integrally with a release lever 9, is designed and mounted such that a specific balanced arrangement is given, so that the sensing pin 8 is pushed against the yarn 11 with a predetermined sensing force, according to an advantageous example of the invention with a force of about 50 to 200 g.
- the sensing lever 7 is here provided with a protruding further arm on its back side with several groove portions 14, into which a balance weight 17 may be placed.
- the balance weight 17 can be adjusted in order to set a predetermined sensing force, which, by the sensing pin 8, is applied onto the yarn 11 passing by in the feed direction F at the feeding speed. From a comparison of Fig. 2 with Fig. 3, the forward and backward movement of the sensing lever 7 with its sensing pin 8 can be taken. Due to the continuous rotation of the rocking cam 15 about its rocking shaft 18, the sensing pin 8 is moved from its contact position with the yarn 11 (Fig. 2) back to the position shown in Fig. 3, in which the sensing pin 8 is in a certain distance from the yarn 11 passing by.
- the sensing pin 8 is again brought into pushing contact with the yarn 11, as the balance weight 17 and the form and mounting of the sensing lever 7 are provided such that the sensing lever 7 will due to the gravity move against the yarn 11 (left-hand side in Figs. 2 and 3).
- the rocking cam 15 comes into contact with a leaf-spring- type element 16 provided at the inside of the sensing lever 7.
- the leaf-spring-type element 16 is a flexible part, which avoids the sensing lever 7 from being damaged in a yarn break situation, which will be explained in more detail later in this specification.
- the sensing lever 7 is provided with a release part or release lever 9.
- the release lever 9 is also moved forward and backward, which is in the drawings shown by arrow B.
- the release lever 9 is provided with a release part 9a, which is in this example realized in the form of a longitudinal groove open to one side.
- the longitudinal release part 9a is in this situation of a normal, correct functioning of the drafting device in engagement with an engagement part 12f of a clamp device 12.
- the clamp device 12 is shown in its open state, which means that the clamps 12a, 12b are open and provide a certain gap, which is sufficiently large for the passing of the rove 13 coming from the delivery side of the rove material
- the clamps 12a, 12b are pivotally mounted to one another, respectively, and have an outer cam surface, which is formed such that upon closing of the clamp device an increasing clamp effect is created on the rove 13.
- the clamps 12a, 12b of the clamp device 12 are furthermore provided with meshing gears 12c on one side of the clamp device 12, which is in a position beside the rove 13.
- the meshing gears 12c provide a combined movement of the clamps 12a, 12b and the activating lever 12d and the release lever 12e, which will be described in more detail with regard to the following figures.
- the forward and backward movement of the release lever 9 (cf. arrow B in Figs. 2 and 3) is realized such that the engagement portion 12f of the clamp device 12 remains in any situation within the longitudinal release groove 9a of the release lever 9, so that the clamp device
- the elements and components of the stopping device 10 are provided with screwless mounting means 5, 6 in order to be easily replaced in case of damage.
- the screwless mounting means 5, 6 are, for example, formed as clip-on elements, which may be mounted on mounting pins by means of a clipping action.
- the sensing lever 7, the release lever 9 and the rocking cam 15 are mounted on a common support element 19.
- the complete stopping device with the sensing lever 7, the rocking cam 15 and the clamp device 12 may therefore easily be installed in existing spinning apparatuses as a so-called retrofit device.
- the components and parts of the stopping device 10 are preferably made of a resin material, such as plastic, so that the device 10 may also be used in corrosion- aggressive environments, such as wet spinning apparatuses.
- the material of the components of the stopping device is chosen such that they are resistant to temperatures of up to 80° C.
- the stopping device according to the invention is therefore resistant to water, oil and normal chemicals.
- the rather simple construction of the mechanical parts of the stopping device 10 does not require lubrication or maintenance activities.
- the clamp device 12 is provided with a preloading spring, which is preferably mounted within one or both of the clamps 12a, 12b, so that the spring is not exposed to the sometimes wet surroundings and may be made of metal.
- the preloading spring is installed in the clamp device 12 such that, upon release of the engagement part 12f of the clamp device from the release groove 9a, the clamps 12a, 12b will
- the release lever 9 has a release part 9a, here in the form of a longitudinal groove, which is dimensioned such that the engagement portion 12f of the activating lever 12d of the clamp device will leave the engagement with the release lever 9 (cf. Fig. 5).
- the preloaded clamp device 12 will then automatically be closed due to the force of a preloading spring, which is provided within the clamp device 12 either on one clamp or on both clamps 12a, 12b.
- the closing of clamps 12a, 12b is indicated in Fig. 5 by arrows D.
- meshing gears 12c are here provided besides the rotational clamps 12a, 12b of the clamp device 12, the movement of the eccentric clamps 12a, 12b is combined and counter-acting, which means that the two clamps 12a, 12b rotate in opposite directions, so that the cam surfaces of the eccentric clamps 12a, 12b comes into contact with one another as well as with the rove 13 to firmly hold the rove 13 and to prevent a further delivery in the feed or delivery direction F.
- the end of the broken rove 13 is firmly held by means of the clamps 12a, 12b of the clamp device.
- the two counter-acting clamps 12a, 12b have an eccentric protruding part with a curved surface of approximately a quarter of a circle.
- the engagement portion 12f can easily be introduced into the groove-like engagement portion 9a, and the end of the rove 13 may be connected to the already drafted yarn 1 1 on the output side of the drafting zone.
- the stopping device 10 can be mounted completely outside of the drafting zone A from behind of the spinning apparatus and with the sensing pin 8 on the output side of the drafting zone, whereas the clamp device 12 is positioned in a distance from the back rollers 1, 2, so that in any situation the further supply of rove 13 into the drafting zone A is effectively prevented.
- the clamp device is according to one further aspect of the invention located in distance of 15 to 12 cm from the back rollers 1, 2. Any interference with critical parts in the drafting zone A is hereby prevented.
- the stopping device 10 may have a different type of clamp device 12.
- a clamp device 12 could have only one eccentric clamp, which has a fixed counter- element, which provides the same function of an increased clamping force due to the further pull from the side of the drafting area A due to the continued rotation of the rollers 1, 2, 3, 4.
- the construction and form of the sensing lever 7 with the release lever 9 and the release part 9a can be modified within the scope of the invention as defined in independent following claim 1 : the lever 7, 9 is not necessarily provided in an approximately L-shaped form.
- the release part 9a can be an open surface instead of a groove-like element.
- the balance weight 17 with the weight adjustment positions 14 can be eliminated provided that the form and position of the pivot axis X are chosen in such a manner that the repeated pushing of the sensing pin 8 can be accomplished. Also, the form of the rocking cam 15 can be different as long as the repeated rocking movement of the sensing lever 7 is realized.
