No. 406,052 Claims priority, application France, Oct. 24, 1963, 951,600 3 Claims. (Cl. 57-83) This invention relates to textile machinery for processin slivers, roves, or yarns, such machines consisting of a series of stations each of which comprises first means, such as a drawing device, for feeding second means, such as a spinning spindle, the first means of each station being driven by a common drive means, an example being a shaft co-extensive with the full length of machine.
In what follows, reference will often be made hereinafter only to drawing devices and spinning spindles for greater clarity, but it is to be understood that other means for processing the slivers, roves or yarns may be used.
When the sliver, rove or yarn in one of the stations breaks between exit from the drawing device and entry into the corresponding spinning spindle equipment, overfeeding occurs therebetween, whereas all the other stations of the machine are capable of continuing to work normally.
Two different solutions have already been put forward for solving this problem, to wit, halt the machine in order to repair the breakage, or else resort to means for absorbing the excess material fed in.
Shutting down the whole machine will make all of the stations including the failed station irnproductive, which is manifestly highly detrimental to effective operation.
Among the means of absorbing the excess feed material, so-called swallower cylinders and suction systems have already been resorted to, but these obviously lead to waste material which it is imperative to reduce as far as possible.
This invention has for its object to provide means for individually preventing each drawing device from continuing to feed its associated spindle after the rove has broken therebetween.
The subject machine of this invention is characterized in that eachstation is provided with a separate stop motion device activated upon asliver, rove or yarn breaking, which is positioned between the drawing device and the spindle device and which controls means for stopping feeding of the sliver, rove or yarn in the station concerned without halting the advance of said sliver, rove or yarn in the other stations.
In one specific constructional form, the link between the first device of each station and the common drive means referred to precedingly comprises a coupling releasable in response to actuation of an individual stop' motion device each time a break occurs.
Where said common drive means is a shaft co-extensive with the machine throughout its entire length, each coupling comprises a driving dog which is rigidly connected to a part keyed to said shaft and which drive a pawl pivotally connected to a plate which is in turn coaxially pivotable on a. drum which rotates loosely on said shaft and which is connected to the first device to be driven of the station under consideration, said pawl being urged toward its position of engagement with said dog by a cam rigid with said drum, responsively to a spring interconnecting the drum and the plate, which'plate is proice vided with a ratchet positioned whereby to be arrestable by a retractable arresting stop which is fetched into its operative position responsively to said stop motion device, in such manner that when said abutment suddenly stops the plate, the dog, which is still positively driven by the drive shaft, repels the pawl by causing it to pivot against the bias of its return spring, whereby the coupling between said shaft and the drum linked to the device to be driven is interrupted.
The description which follows of a form of embodiment of an improved continuous spinning machine, with reference to the accompanying non-limitative exemplary drawings, will give a clear understanding of how the invention can be carried into practice.
In the drawings,
FIGURE 1 shows in plan View, with cutaway portions, a part of the drawing device of the machine, the upper intermediate pressure rolls and the sleeves thereof having been removed for greater clarity,
FIGURE 2 is a section taken through the line IIII of FIGURE 1,
FIGURE 3 is a section taken through the line III-III of FIGURE 1,
FIGURE 4 is a partial section taken through the line IVIV of FIGURE 3, and
FIGURE 5 shows a detail of FIGURE 3.
Referring to the accompanying drawings, the continuous spinning machine fragmentally illustrated thereon .comprises a number of drawing stations such as P1, P2, etc., only two stations being shown in the drawing. Each station has three lower splined rolls 1, 2, 3, which cooperate with three smooth upper pressure rolls 4, 5, 6, respectively. On rolls 2 and 5 are mounted two sleeves 7 and 8, respectively. Reference numeral 10 designates the rove of textile fibres passing into the drawing station.
In the manner well known per se, the three upper pressure rolls 4, 5 and 6 of the drawing station P1, for instance, are mounted on shafts common to the corresponding three upper pressure rolls of the adjacent station P2, the three shafts being carried on a common pressure arm 12 pivotally mounted on the machine frame, whereby it may be raised if necessary in order to enable the upper rolls to be moved away from the lower rolls.
The three pressure rolls 4, 5 and 6 are freely rotatable and are frictionally driven by the cooperating positively driven lower rolls.
All the lower drawing or exit rolls of each station (such as the rolls 1) are accordingly mounted on a common drive shaft 14 which is coextensive with the machine throughout its entire length and is driven by any convenient power means (not shown).
The other two lower rolls of each station (such as the rolls 2 and 3) are driven through a special transmission system by a further shaft 15 which is likewise coextensive with the full length to the spinning machine and which is permanently coupled to the shaft 14 through a train of gears 16, 17, 18, 19 (see FIGURE 1). The total number of gearwheels in this train is an even number,
whereby the shaft 15 rotates in the opposite direction to the shaft 14.
Mounted loosely on shaft 15 is a sleeve 22 bearing thereon a gearwheel 23 which meshes simultaneously with two gearwheels 24, 25 (see also FIGURE 2) rigidly connected to the lower rolls 2, 3, respectively.
A drum 27 is mounted on the sleeve 22 and is rendered rigid therewith by longitudinal pegs 29 which extend through a collar 31 of sleeve 22'and penetrate into notches on the corresponding face of the hub of said drum. The drum 27 is positioned axially on sleeve 22 by an elastic keeper-ring 33 located in a corresponding groove formed in the outer cylindrical surface of said sleeve and bearing against the other face of said drum hub.
A disc 35, which is rendered rigid with the shaft 15 by a key 36, carries one or more dogs 38 (shown as numbering two in the illustrated example) normally in en gagement with a pawl 41 pivotally mounted on a pin 42 rigidly connected to a plate 28 which is mounted loosely on the hub of drum 27. The pin 42 extends with a large clearance through a wide opening 43 formed in the web of drum 27.
The end of the pawl 41 remote from its pivot carries a follower 45 engaging with a radial cam groove 46 which is likewise formed in the hub of drum 27 (see also FIG- URE The drum 27 is urged to rotate in the opposite direction to the arrow 1 relatively to the plate 28, by a return spring 48 one of whose ends is fastened to a stub 49 rigid with plate 28 and the other end to .a stub 51 rigid with drum 27.
The periphery of plate 28 has formed thereon notches 53, with which a retractable stop 54 is adapted to engage whereby to prevent rotation of said plate. When this stop is in the inoperative position shown in solid lines in FIGURE 3 it allows the plate 28 to rotate freely, whereas when it is in its operative position shown in broken lines it engages with one of said notches and prevents rotation of said plate.
The retractable stop 54 is actuated by a mechanical or (as assumed herein) electromagnetic system governed by a stop motion device responsive to a rove-breaking 56, which comprises an electric contact 61 activated by a feeler 57 terminating in a rove guide 58. On issuing from the drawing station the rove runs over a guide 59 before passing through the rove guide 58.
The electromagnetic device 55 for actuating the retractable stop 54 basically comprises an electromagnet 63 whose moving core 64 is connected through a link 65 to an extension of the retractable stop 54, which stop pivots about a pin 66. A retractile spring 68 urges the stop 54 into its inoperative retracted position, while on being energized the electromagnet moves said stop into its lower operative position against the bias of said spring. The coil of electromagnet 63 is energized by a suitable source of current S, under control of the stop motion device eleotric contact 61.
The operation of the system hereinbefore described as the following:
In normal operation the primary drive shaft 14, which rotates continuously, in turn continuously rotates the shaft through the train of gears 16, 17, 18, 19. The rove 10, when normally fed between the drawing device and the spinning spindle, exerts a uniform pressure on the yarn-guide 58 of feeler 57, whereby the stop 54 is maintained in its retracted position and one of the dogs 38 of disc 35, which rotates in the direction of arrow f1 moves the pawl 41 along with it. Being pivotally mounted about the pin 42, the pawl 41 rotates the plate 28 and, through the agency of spring 48, also rotates the drum 27 and the sleeve 22 rigid therewith. The gearwheel 23 rigid with said sleeve is thus made to rotate the lower restraining and feed rolls 2 and 3, respectively, of the drawing station.
The return spring 48 tends to rotate drum 27 in the opposite direction to arrow f1 relatively to the plate 28, i.e. relatively to the pawl, thereby causing the cam 46 of said drum to tend to make the pawl 41 pivot outwardly, i.e. in the direction whereby it is kept engaged with the dog 38 driving it.
Should the rove break on emerging from the drawing device, the contact 61 of stop motion device 56 closes and causes the stop 54 to drop into its operative position and to halt the plate 28 sharply and positively. The pivoting pin 42 of said pawl is thus immobilized in space,
whilst the dog 38 rigid with disc 35, which continues to be rotated at the same speed by the continuously rotating shaft 15 with which it is integral, repels the movable end of pawl 41 and constrains it to move toward the axis of the system and, through the cam 46, to consequently rotate the drum 27 in the direction of arrow f1, relatively to the stationary plate 28 and against the countering force of its return spring 48. This motion disengages the pawl from the dog 38, which continues to rotate, whereas the drum 27 stops rotating and the lower restraining and feed rolls 2 and 3, respectively, of the drawing device are halted. The drawing roll 1 continues to rotate, but this has no effect since no more rove is being fed between the drawing rolls.
Although the drawing station under consideration has stopped operating all the remaining stations of the machine continue to operate normally, so that the output of the machine is not appreciably reduced. Thus when a breakage occurs, the end of the feeler 57, for instance, is raised manually, thereby returning the stop 54 into its upper retracted position and causing the various other parts to revert to their initial positions; thus, when the disc 35 describes its next half-revolution one of its dogs 38 engages anew with the pawl 41 and causes the drawing process to be operative once more, thereby enabling the broken rove to be joined up again and the feeler 57 to be released 'as soon as the pressure of the rove thereagainst is sufficient.
While there has been shown and described, the presently preferred embodiment of the improved spinning machine of this invention, it will be well understood by those skilled in the art that various changes and modifications may be made in this embodiment to suit specific applications. It is, therefore, to be understood that the description hereinbefore set forth is not be considered a limitation of the invention, but that changes may be made within the spirit and scope of the invention as set forth of the appended claims.
