Description

Drafting device of spinning machine
Technical Field
The present invention relates to a fiber bundle supply stopping device for a spinning machine that stops supply of a fiber bundle to a draft device.
Background
In a spinning machine that spins a yarn from a roving or a sliver, spinning is performed simultaneously by a plurality of spindles, and even if a yarn break occurs during spinning, spinning is continued by a spindle other than the spindle that generates the yarn break (hereinafter referred to as a "yarn break spindle"). There is a spinning machine that continues to supply a fiber bundle to a draft device corresponding to a yarn breaking spindle and sucks and collects the fiber bundle sent out from the draft device, but there is also a spinning machine including a stopping device that stops the supply of the fiber bundle to the draft device corresponding to the yarn breaking spindle. As one of such stop devices, a roving stop device disclosed in japanese patent application laid-open No. 57-133224 is disclosed.
The roving stop device disclosed in jp 57-133224 a has a stop pawl that fits in a range of more than half the circumference of the rear bottom roller of the draft device. The stop pawl does not rotate integrally with the rear bottom roller when yarn breakage does not occur. When the yarn breakage is confirmed, the stop pawl swings (rotates), and the edge portion of the stop pawl is inserted between the roving yarn and the rear bottom roller and is clamped between the rear top roller and the rear bottom roller of the draft device. Thereby, the transmission of the rotation from the rear bottom roller to the rear top roller is cut off. Further rotation of the stopping claw is then prevented and the roving is held between the stopping claw and the back top roller. At this time, the roving is pulled downstream in the flow direction of the roving from the rear top roller and cut by continuing the driving of the draft device. As a result, the supply of the roving to the draft device corresponding to the yarn cutting spindle is stopped.
For example, when a roving yarn having high breaking strength such as rayon is used in the roving stop device disclosed in jp 57-133224 a, the roving yarn is not cut even if the roving yarn is pulled downstream in the flow direction of the roving yarn from the rear upper roller in a state where the roving yarn is held between the stop claw and the rear upper roller. In this way, for example, the lower apron wound around the middle lower roller and the upper apron wound around the middle upper roller of the draft device slip with respect to the roving and run idle, and the lower apron and the upper apron wear.
Disclosure of Invention
The invention aims to provide a fiber bundle supply stopping device of a spinning machine capable of easily cutting fiber bundles.
The fiber bundle supply stopping device of the spinning machine for solving the above problems includes a stopping member provided with a wedge portion which is caught between a rear upper roller and a rear lower roller of a draft device to cut transmission of rotation from the rear lower roller to the rear upper roller and which sandwiches a fiber bundle supplied to the draft device together with the rear upper roller, the stopping member having a comb tooth at a position upstream of a position where the fiber bundle is sandwiched by the rear upper roller and the wedge portion, the comb tooth untwisting the fiber bundle.

Detailed Description
An embodiment of a fiber bundle supply stopping device 30 of a spinning machine will be described below with reference to fig. 1 to 5. The fiber bundle supply stop device 30 stops the supply of the roving S1, which is the fiber bundle supplied to the draft device 10.
As shown in fig. 1, the draft device 10 has a 3-line structure, and includes a front roller 11, a apron 13 wound around a middle roller 12, and a rear roller 14. The front roller 11 is composed of a front lower roller 11a and a front upper roller 11 b. The middle roller 12 is composed of a middle lower roller 12a and a middle upper roller 12b, a lower apron 13a is wound around the middle lower roller 12a, and an upper apron 13b is wound around the middle upper roller 12 b. The back roller 14 is composed of a back bottom roller 14a and a back top roller 14 b.
The front bottom roller 11a is supported by a roller stand 15. The middle bottom roller 12a is supported by the roller stand 15 via a middle bottom roller support portion 16 and a bearing not shown. The rear bottom roller 14a is supported by the roller stand 15 via a rear bottom roller support portion 17 and a bearing not shown. The middle lower roller support portion 16 and the rear lower roller support portion 17 are fixed to the roller stand 15 so as to be adjustable in position in the front-rear direction of the machine base (the left-right direction in fig. 1).
The pressure lever 18 is rotatably supported via a bracket 20 with respect to a support shaft 19 supported by the roller stand 15. The front top roller 11b, the middle top roller 12b, and the rear top roller 14b are supported by a pressure bar 18 via top roller supports, not shown.
A support rod 21 is disposed behind the back bottom roller 14a so as to extend along the back bottom roller 14 a. A trumpet 22 for guiding the roving S1 is fixed to the support rod 21. The roving S1 is supplied from a roving package suspended from a creel, not shown, to the rear roller 14 via the trumpet head 22.
As shown in fig. 2, the draft device 10 is provided with a fiber bundle supply stop device 30. The fiber bundle supply stopping device 30 includes a stopping member 31, and the stopping member 31 engages with the outer peripheral surface of the rear bottom roller 14a over substantially a half-circumference range of the outer peripheral surface. The stopper member 31 has a crescent shape curved in an arc shape. The stopper member 31 does not rotate integrally with the rear bottom roller 14 a.
As shown in fig. 3A and 3B, comb teeth 32 are provided in a region near one end (tip) of the outer peripheral surface of the stopper member 31 in the bending direction. The comb teeth 32 have a plurality of teeth 32 a. The plurality of teeth 32a are formed in a plurality of rows of teeth arranged in a direction orthogonal to the flow direction of the roving S1, and the rows of teeth are arranged adjacent to each other in the flow direction of the roving S1. In the present embodiment, the teeth rows are arranged in 4 rows in the flow direction of the roving S1, and the teeth 32a of each tooth row are arranged with a half pitch offset relative to the teeth 32a of the other adjacent tooth row in the flow direction of the roving S1. Further, a wedge 33 is formed at a position of the stopper 31 on the front end side of the comb teeth 32 to be caught between the rear upper roller 14b and the rear lower roller 14 a.
As shown in fig. 4, the stopper member 31 is swingable between a fiber bundle releasing position shown by a two-dot chain line and a fiber bundle clamping position shown by a solid line. The stopper 31 is separated from the rear top roller 14b at the tow release position, and the tow is nipped by the rear top roller 14b and the wedge 33 at the tow nipping position. A columnar driving force transmission member 36 is connected to the stop member 31 via a bracket 35.
As shown in fig. 1, a switching device 37 is coupled to an end portion of the driving force transmission member 36 on the opposite side to the bracket 35. The switching device 37 is controlled by a control device, not shown, based on a detection signal of a yarn breakage sensor, not shown. That is, the configuration of the switching device 37 is not particularly limited, and it is sufficient if the position of the stopping member 31 is switched between the tow release position and the tow pinching position via the driving force transmitting member 36 and the bracket 35 by being controlled by the control device based on the detection signal of the yarn breakage sensor.
As shown in fig. 4, in the present embodiment, the driving force transmission member 36 reciprocates linearly with the switching device 37 being driven. Then, the stopper member 31 swings via the bracket 35 in accordance with the reciprocating linear motion of the driving force transmitting member 36. The comb teeth 32 can abut against the rear top roller 14b, and when the comb teeth 32 abut against the rear top roller 14b, the stop member 31 is restricted from further swinging, and the stop member 31 is positioned at the fiber bundle nipping position.
In a state where the stopper 31 is positioned at the fiber bundle nipping position, the wedge 33 is caught between the rear top roller 14b and the rear bottom roller 14a, and nips the roving S1 together with the rear top roller 14 b. In this state, the comb teeth 32 penetrate the roving S1 at a position upstream of the position where the roving S1 is nipped by the rear top roller 14b and the wedge 33 in the flow direction of the roving S1. "upstream" is defined in terms of the direction of flow of the rovings S1.
Next, the operation of the present embodiment will be described.
In the non-broken state, the stopping member 31 is held at the tow release position. The non-broken yarn state refers to a state in which the roving S1 is supplied to the draft device 10 through the trumpet head 22 and spun, and also refers to a state in which the roving S1 is not supplied to the draft device 10 before the start of spinning. In a state before the start of spinning, even if the yarn breakage sensor does not detect the yarn, the control device does not determine that the yarn is broken and does not drive the stopper member 31 to the fiber bundle pinching position by the switching device 37.
When the operation of the spinning machine is started, the roving S1 supplied from the roving roll suspended from the creel, not shown, is guided to the trumpet head 22 and supplied to the rear roller 14. The roving S1 supplied to the rear roller 14 is drafted between the rear roller 14 and the apron 13 and between the apron 13 and the front roller 11 to be a carded yarn (yarn) which is wound as a yarn around a not-shown bobbin via a not-shown yarn guide and a not-shown traveler.
When the yarn breakage occurs, the yarn breakage spindle is identified by the detection signal of the yarn breakage sensor, and the switching device 37 corresponding to the yarn breakage spindle is driven by the control device. By driving the switching device 37, the stopper 31 swings from the tow release position to the tow nipping position, and the wedge 33 is caught between the rear upper roller 14b and the rear lower roller 14a, thereby cutting off the transmission of the rotation from the rear lower roller 14a to the rear upper roller 14 b. The wedge 33 clamps the roving S1 together with the rear top roller 14b, and the comb teeth 32 come into contact with the rear top roller 14b, thereby restricting further swinging of the stopper member 31. Thereby, the stopper member 31 is positioned at the fiber bundle clamping position. The comb teeth 32 penetrate the rovings S1 at a position upstream in the flow direction of the rovings S1 from the position where the rovings S1 are nipped by the rear top roller 14b and the wedge 33. When the roving S1 passes through the comb teeth 32 as the draft device 10 is driven, the roving S1 is carded by the comb teeth 32 and untwisted.
As shown in fig. 5, the teeth 32a of each row are arranged with a half pitch offset relative to the teeth 32a of another row adjacent to the roving S1 in the flow direction, and therefore the fiber S2 forming the roving S1 is easily branched by the teeth 32 a. Thereby, the roving S1 is efficiently untwisted. Further, entanglement of the fibers S2 is weakened, the strength of the roving S1 is reduced, and even when the strength of the roving S1 is large, the roving S1 pulled by the driving of the draft device 10 is reliably cut between the back roller 14 and the apron 13. Even if the driving of the draft device 10 is continued, the transmission of the rotation from the rear bottom roller 14a to the rear top roller 14b is cut by the wedge 33, and therefore, the supply of the roving S1 of the draft device 10 to the spindle in which the yarn breakage occurs is stopped.
The following effects can be obtained in the above embodiment.
(1) The stopper 31 has comb teeth 32 for untwisting the rovings S1 at a position upstream in the flow direction of the rovings S1 from a position where the rovings S1 are nipped by the rear top roller 14b and the wedge 33. Thus, when the roving S1 passes through the comb teeth 32 as the draft device 10 is driven, the roving S1 is carded by the comb teeth 32 and untwisted. This weakens the entanglement of the fibers S2 forming the roving S1, and reduces the strength of the roving S1, so that the roving S1 pulled by the driving of the draft device 10 can be easily cut.
(2) The comb teeth 32 can abut against the rear upper roller 14 b. The comb teeth 32 abut against the rear top roller 14b, so that the positional accuracy of the stopper member 31 with respect to the rear top roller 14b can be improved. Therefore, the wedge 33 can be accurately caught between the rear top roller 14b and the rear bottom roller 14 a.
(3) For example, even when the roving S1 is a high breaking strength roving S1 such as rayon, the roving S1 is carded by the comb teeth 32 and untwisted, whereby entanglement of the fibers S2 forming the roving S1 is weakened and the strength of the roving S1 can be reduced. Therefore, the roving S1 having high breaking strength can be cut. Therefore, it is possible to prevent the lower apron 13a and the upper apron 13b from slipping and idling with respect to the roving yarn S1 due to the roving yarn S1 not being cut, and to prevent a problem such as abrasion of the lower apron 13a and the upper apron 13 b.
(4) The teeth 32a of each tooth row are arranged with a half pitch offset from the teeth 32a of the other tooth row adjacent to each other in the flow direction of the roving S1. Accordingly, when the roving S1 passes through the comb teeth 32 as the draft device 10 is driven, the fiber S2 is easily branched by the plurality of tooth rows, and thus the roving S1 can be more efficiently untwisted.
The above embodiment may be modified as follows.
In the embodiment, when the wedge 33 is caught between the rear top roller 14b and the rear bottom roller 14a and the roving S1 is nipped together with the rear top roller 14b, the driving of the switching device 37 can be controlled with high accuracy to restrict the stop member 31 from further swinging, and the comb teeth 32 may not come into contact with the rear top roller 14 b. As shown in fig. 6A and 6B, the stopper 31 may have projections 34 formed separately from the comb teeth 32 on both edges in the direction perpendicular to the flow direction of the rovings S1, and in contact with the rear top roller 14B. When the stop member 31 swings from the fiber bundle releasing position to the fiber bundle nipping position, the convex portion 34 abuts on the rear top roller 14b earlier than the comb teeth 32, and the comb teeth 32 are prevented from abutting on the rear top roller 14 b. Thus, the stop member 31 can be positioned without fear of damage to the peripheral surface of the rear top roller 14b due to the contact of the comb teeth 32 (teeth 32a) having a sharp tip end with the rear top roller 14b for carding the roving S1.
In the embodiment, the teeth 32a of each tooth row and the teeth 32a of the other tooth row adjacent to each other in the flow direction of the roving S1 may be arranged without being relatively shifted by half pitch, or may be arranged at the same pitch.
In the embodiment, the teeth may be arranged in 2 rows or 3 rows in the flow direction of the roving S1. The rows of teeth may be arranged in 5 rows or more in the flow direction of the roving S1.
In the embodiment, only one row of teeth extending in the direction orthogonal to the flow direction of the roving S1 may be arranged.
In the embodiment, the plurality of teeth 32a may be arranged adjacent to each other at least in the direction intersecting the flow direction of the rovings S1, and may not intersect the flow direction of the rovings S1.
In the embodiment, the fiber bundle is not limited to the roving S1, and may be a sliver. For example, the fiber bundle supply stopping device 30 may be used in a ring spinning frame that spins a yarn from a sliver using a draft device that drafts a fiber bundle at a draft ratio much higher than that of a typical 3-line draft device.
In the embodiment, the spinning machine is not limited to the ring frame, and may be, for example, a wrap spinning device or a friction spinning device.
In an embodiment, the spinning machine may also be a roving machine.
