Abstract
- - means (11) for checking with blade means (13), and
- -means (18) for causing the opening of said blade means (13), whereby re-positioning means (39) and means (17) to regulate the opening of said blade means (13) are included.
Description
- This invention concerns a device for checking knots and for controls downstream from the slub catcher in winding machines.
- To be more exact, the invention concerns a device which enables the quality of the knots to be checked as soon as knotting has taken place and which makes it possible to ascertain whether the yarn rising towards the yarn package during winding contains tangles, slubs, broken ends of thread or other like faults.
- Some devices are hnown which perform the task of a slub catcher and check the knots as soon as the latter are formed.,
- Infact search RS 64371 IT made at the European Patent Office reveals various devices of this type as described in DE-A-2.705.080, DE-B-2.934.544, GB-A-726.294, GB-A-596.999, CH-A-507.145 and DE-B-2.543.983.
- Nevertheless these known devices are rather complicated and require complicated actuation means.
- Furthermore alongside some of said devices for better results another device may be required to carry out proper controls downstream from the slub catcher and to be able to . eliminate tangles in the yarn rising towards the yarn pack- . age, thereby improving the control already performed by the . slub catcher.
- A purpose of the invention is to embody an improved single device for checking knots and for the controls downstream from the slub catcher, whereby said device is simple in con-. struction reliable and provides easy operation and adjustment
- Another purpose of the invention is that the control on the yarn to be wound may also be conducted while said yarn is being transferred from the knotting position to the pos- . ition of the slub catcher, thereby substantially providing a continuous inspection of said yarn during the whole wind- . ing cycle.
- So as to fulfil said purposes, the device of the invent- . ion comprises two blade means for controlling and guiding the yarn which extend lengthwise above the knotter and above. the slub catcher so as to cooperate with both of them, whereby one of said blade means is located in a pre-set and per- . haps adjustable position, and whereby the other blade can be. moved or rotated from its open position of rest to its clos-. ed working position.
- The length of time of the conditions of rest or of work can be varied by altering the reciprocal positions of read- . ing means and two-can means which cooperate with each other,. whereby the position of said reading means can be regulated . axially.
- This invention is therefore embodied in a device for checking knots and for controls downstream from the slub catcher. in winding machines, said device being characterized by com-. prising:
- - means for checking the yarn with blade means, and
- - means to cause the opening of blade means,
- We shall give hereinafter a description of a preferential. embodiment of the invention as a non-restrictive example and. shall make references to the attached table, where in:
- Fig. 1 gives a three-dimensional view of the device of the invention in its position of rest; .
- Fig. 2 gives a three-dimensional view of the device of Fig.1. in its working position;
- Fig. 3 shows a plan view of the two-blade means which check . the yarn;
- Fig. 4 gives a side view of a detail, cut away along the line C-C, of the means which regulate the opening of the two blades.
- In particular, the
device 10 of the invention comprises means 11 for checking theyarn 12 with blade means 13, where by said blade means 13 consist of a fixed blade means 14 and. of a blade means 15 which can be moved and be at least par- . tially rotated, said two blade means being reciprocally pos-. itionable. - The opening or
slit 16 between said two blade means 14 & . 15 within which theyarn 12 is guided and slides, is obtained by regulating the reciprocal positions of said blade means 14-15 by means of suitable adjustment means 17. - In particular, said opening is dimensioned to suit the basis of the diameter thereof and in relation to the size of. the faults and knots to be eliminated.
- For this purpose it is enough to regulate the axial pos- . ition of a
screw 40 engaged in a threaded throughhole 43 in. theblade 14 and connected (44) correspondingly to thestatio nary structure 26. - The position of said
blade 14 and said stationary struc- . .ture 26 are maintained temporily by the action of athrust spring 41, whereby saidblade 14 is hinged (42) onto thestationary structure 26 and rotates as an outcome of axial .displacement of thescrew 40 so as to enable the breadth of . thelengthwise slit 16 to be varied, as shown in Fig. 4. - Figs. 1 & 2 show the
means 18 which operate the opening . of the blades 14-15 and which consist of acam 19 shown in an exploded view and keyed to the horizontal knotting shaft . 20, and of areading pin 21 passing through an oscillatingarm 22. - The axial position of said
reading pin 21 can be regula- . ted so that saidpin 21 can cooperate with one of two circular crowns 23-123, which are radially superimposed one above the other and into which thecam 19, rotating in direction A (Figs. 1 and 2), is divided so as to obtain a differing length of time for the opening or closing of the blades 14-15. - In our example the
circular crown 23 permits said blades 14-15 to be closed for a period limited to the knotting phase, whereas thecrown zone 123 causes said bladed 14-15 to be closed during the normal winding phase. - When the
reading pin 21 acts on thesloping sector 24 of . the radial crown 23 (Fig. 1), the oscillatingarm 22, being hinged at itstop 25 to thestationary structure 26, is kept. in its position of rest by suitable re-positioning means 39, . which consist of apiston 29 pressed by athrust spring 27 with which said piston cooperates coaxially. - In particular, said
spring 27 is kept under axial compression between theend 30 of saidpiston 29 pushing against said. oscillatingarm 22, and aresistance point 28 on the stat-ionary structure 26. - The
other end 130 of thepiston 29 keeps in a retracted or non-operational position therotating blade 15, onto which the saidend 130 is hinged (31). - Said rotating blade (15) comprises a
second pivot 32 near. to the procedingpivot 31, whereby saidpivot 32 enables saidblade 15 to rotate around thestationary structure 26 with an arm cf rotation of which the length is equal to the distance. betweene the two pivots 31-32 located in theend 45 of said . rotatingblade 15. - Fig. 1 shows the position of rest of the
device 10, where as Fig. 2 shows thesame device 10 in its working position.. - In particular, in Fig. 2 the
reading pin 21 cooperates with thesector 124 of thecircular crown 123 of the double .cam 19 and, to be more exact, with thefront part 33 thereof. 19. - In such working conditions the oscillating arm 122 is rotated in direction B and pushes against the
piston 29, thereby compressing thethrust spring 27. - In its turn said
piston 29 makes theblade 15 revolve into the closed or working position by means of itsend 130 hinged 31 onto saidblade 15. - Thus the checking of the knot just formed can be carried out in a position or
zone 34 of thelengthwise slit 16 above theknotter 36. - The
yarn 12 can be transferred thereafter by sliding tangentially on thefixed blade 14 up to theopposite zone 134 of saidslit 16 abcve theslub catcher 37, saidzone 134 cor7 responding to the position where saidyarn 12 passes during . the winding phase, as shown in Fig. 3. In Fig. 3 the mcvabel.blade 15 is shown with lines of dashes when it is in its po-. sition of rest (opened) and with a continuous line when it is in its (closed) working position. - Said fixed
blade 14 comprises in said zone 134 atangential porcelain guide 35, which enables said fixedbade 14 to cooperate better with theyarn 12 tangentially thereupon, and also comprises aprotruding terminal stop 38, which prevents. saidyarn 12 from escaping the control of the blade means 13. - When the
reading pin 21 acts on theradial zone 23 of cam. 19, the movable blade means 15 is returned to its retracted . position as soon as said readingpin 21 enters thesector 24. - Instead, when the
reading pin 21 cooperates with the cir-.cular crown 123, therotating blade 15 stays closed against the fixedblade 14 so as to carry out therewith its controls, downstream from the slub catcher. - We have described here a preferential embodiment of the invention, but variants are possible for a technician in this field.
- Thus the shapes and sizes can be changed. It is possible to envisage a different system of cooperation between the means which re-position 39 the blade, or else it is possible to foresee the use of means which are mechanically different but which are able to perform the functions described. It is possible to visualize the employment of multiple-cam means having a number of circular crowns other than two.
- These and other variants are all possible for a technician in this field within the scope of the idea of the solution of the invention.
