Abstract
Description
- The present invention relates to a so-called "piece-pulling device", that is a device designed to draw the knitted fabric produced by a circular machine and wind it in a roll.
- The invention also relates to a circular knitting machine, and in particular to a machine with rotating cylinder, equipped with a piece-pulling device of the aforesaid type.
- In the knitted fabric manufacturing sector the use of piece-pulling devices which are positioned underneath the cylinder of the knitting machine and rotate with it to receive and wind the fabric on a piece-winding beam or roller as it is produced by the cylinder of the machine are known. Equipping these piece-pulling devices with a cutting means which gradually cut the tubular fabric being drawn along a longitudinal line, to open it out, so that it is wound as a simple fabric rather than a tubular fabric on the piece-winding roller is also known. An example of piece-pulling device of this type is described in EP-A-0456576.
- These piece-pulling devices have a pair of diverter rollers, with axes parallel and reciprocally side by side, positioned directly underneath the needle cylinder of the knitting machine. The tubular fabric which is delivered in cylindrical form from the needle bed is guided between the diverter rollers to be laid flat with a double thickness. Positioned immediately upstream of these diverter rollers is the blade which cuts the tubular fabric along a longitudinal line and positioned downstream of the cutting blade are a pair of divaricating rods which, with an effect combined with the effect of the two diverter rollers, open out the fabric to lay it flat. The fabric laid out flat then passes through a series of spreading, traction and guide rollers to be wound on the piece-winding beam or roller.
- Whilst the piece-pulling device is drawn in rotation by a mechanical coupling (obtained by means of drawing arms) to the rotating needle cylinder of the knitting machine to which it is interlocked, the parts on the piece-pulling device receive motion typically from a pulley or gearwheel fixed to the base and cooperating with a mechanical drive which distributes motion to the rollers of the piece-pulling device. The rotary movement imparted to the piece-pulling device causes transmission of motion to its parts.
- The fabric, opened out and laid flat, is pulled by one or more rollers positioned downstream of the zone in which the tubular fabric is cut longitudinally and laid flat. This means that the point in which the fabric is pulled is distant from the point in which the longitudinal cut is made. Due to the distance between the cutting device and the first motorized roller which imparts traction to the fabric to impart the correct tension to the fabric in the cutting and opening out zone, the traction exerted by the underlying rubber rollers must be increased.
- In a machine to produce tubular fabric the distance between the zone in which knitted fabric is produced and the pair of piece-pulling rollers, that is the pair of motorized rollers which the fabric encounters first, is approximately 65 cm. When, on the other hand, there is a cutting device and the relative parts to lay the open fabric flat, due to the complex feed path of the fabric, the distance between the zone in which the knitted fabric is produced and the zone in which the traction rollers of the fabric are positioned increases to approximately 180 cm, meaning that the feed path of the fabric between the zone in which the knitted fabric is produced and the point in which traction is applied to draw the fabric from the production zone to the winding zone is approximately 180 cm.
- This makes it necessary to apply considerable traction to the fabric. This increased traction (compared with machines in which the fabric is not cut and laid flat) causes:
- change in the structure of the knitted fabric, with deterioration in the quality of the fabric;
- increase in the difference between the beginning and end of the roll of wound fabric. This difference is always present, due to the type of winding utilized, which is a peripheral type winding, that is obtained with a friction force applied to the outside of the roll being formed. This difference becomes unacceptable when the length of fabric wound in a roll is substantial and when the traction applied to the fabric is considerable. This unacceptableness is due on the one hand to the difference in weight per square meter between the beginning and end of each piece of fabric wound on each single roll, and on the other hand to the narrowing of the width of the roll from the beginning to the end of the piece of fabric.
- The object of the present invention is to produce a piece-pulling device which limits or overcomes the aforesaid drawbacks, reducing tensile stress on the fabric and the relevant consequences in terms of quality of the finished piece.
- In substance a piece-pulling device is provided comprising: a pair of diverter rollers with axes parallel to and side by side with each other, associated with a cutting device which cuts the tubular fabric produced by the circular machine along a longitudinal cutting line; downstream of the cutting device, an underlying pair of divaricating rods which open the fabric and lay it flat; underneath said rods, a series of traction and guide rollers, at least one of which is motorized, to pull the fabric and wind it on a piece-winding roller. Characteristically, the diverter rollers are motorized and exert a traction force on the fabric.
- In this way a traction force is exerted on the fabric in proximity to the cutting device and therefore much nearer to the zone in which the knitted fabric is produced, compared with normal piece-pulling devices. The entire fabric is thus subjected to less tensile stress, with consequent advantages to the quality of the fabric.
- Although it is possible to provide a dedicated transmission to operate the diverter rollers, according to an advantageous embodiment the diverter rollers take their motion from said at least one motorized roller of the series of traction and guide rollers positioned downstream of the cutting device and which drive and guide the fabric laid flat.
- In a manner known per se, the piece-pulling device may comprise a pair of supporting uprights of the series of traction and guide rollers and a pair of bars, each supported at a first end by one of said uprights and converging with the respective second ends to form a support for the diverter rollers. According to the invention, in this case a kinematic transmission may be developed along at least one of said bars to transmit motion to the diverter rollers. The kinematic transmission may comprise a shaft housed inside said bar. The shaft may be equipped with end universal joints for connection to axles keyed on which are respective pinions which receive and transmit motion by means of flexible organs, in particular chains or equivalent.
- Further advantageous characteristics and embodiments of the device and of the machine according to the invention are indicated in the attached claims.

-
- The circular knitting machine comprises a fixed annular structure 1 (Fig.1) supporting a
needle cylinder 7, developed around a vertical axis Z-Z, rigidly fixed to which are three supportinglegs 3 positioned, in plan, at about 120° from one another. Traditionally, this annular structure 1 supports, by means of ball bearings, a cylinder-supportingring 5, rigidly fixed to which are theneedle cylinder 7 and a drawing gear 9 which receives motion from a motor by means of a transmission not shown in the drawing. The supportinglegs 3 are fixed to the lower part of the annular support 1 and extend radially outward to leave, under the support 1, a large space which houses a piece-pulling device 11, described hereunder and which rotates rigidly with theneedle cylinder 7 around the axis Z-Z. - At the end resting on the ground, the
legs 3 are connected rigidly to one another by means of a flat base 13 (see also Fig.3) in metal section bars welded to one another, extending in proximity to the ground. Asupport 15, designed to sustain the piece-pulling device 11 to allow rotation around the axis Z-Z, is rigidly fixed to thebase 13, in correspondence of the axis Z-Z. - The support 15 (see Fig. 4) comprises a coupling flange 15A rigidly fixed to a counterflange 13A, welded to the
base 13, and integral with apin 15B extending upward and coaxial with the axis Z-Z. Inserted on thepin 15B, with the interposition of a double ball bearing 15E, is an idle hub 15C, designed to axially and radially sustain the entire mass of the piece-pulling device and of a piece-winding roller or beam on which the fabric is wound. For this purpose, a flange 16, fixed by means of bolts to the hub 15C, haswings 16A facing outward and upward, fixed by means of bolts to alower crosspiece 17 of the piece-pulling device. Fixed to the upper end of thepin 15B is atoothed pulley 15F for a belt transmission designed to motorize the rollers of the piece-pulling device 11, as shall be better explained hereunder. - The end of the
lower crosspiece 17 of the piece-pulling device 11 is fitted withrespective uprights 19, 21 (see Figs. 1 and 2), the upper parts of which are connected to each other by means of ahorizontal front bar 23 and a pair ofrear bars 25 joined to each other at one end at the level of the sagittal plane of the line a-a (Fig 3) of the piece pulling device. The piece-pulling device 11 is made to rotate around the axis Z-Z together with theneedle cylinder 7 by means of two drawing arms 8 (see in particular Fig.1). Each of thesearms 8 is fixed at one end to the cylinder-supportingring 5, and at the other end to the corresponding upright 19 or 21 of the piece-pulling device 11 by interposing atorque limiting pin 8A, designed to break or release itself when something accidentally prevents rotation of the piece-pulling device 11, to thus safeguard the integrity of the machine. - Respective supports 27, 29 (see in particular Figs. 2 and 3) are fixed to the middle part of the
bar 23 and at the joining end of thebars 25 to sustain a pair ofdiverter rollers 31 with axis horizontal and orthogonal to thefront bar 23. The twodiverter rollers 31 are parallel to and side by side with each other so that the tubular fabric produced by the needle cylinder of the circular machine is flattened and made to lie on a vertical plane passing between the tworollers 31, which cooperate with parts to be described hereunder to open the fabric out flat after it has been cut longitudinally in the manner to be described. - Fixed to the ends of the
bar 23 are respective horizontal rectilinear divaricatingrods 33, 35 (Figs. 2 and 3), underneath therollers 31 and inclined by about 45° in plan in relation to thebar 23; these rods join in a unitingelement 37 provided (in the example shown) with anidle wheel 39 with a horizontal axis.Respective rollers rods - Underneath the
rollers pulling device 11 comprises a series ofdrive rollers others toothed pulley 15F. - The
tubular fabric 59A coming from the needles of thecylinder 7 is conveyed between thediverter rollers 31 and is maintained laid flat by means of aguide structure 60 formed of two pairs ofrods rods rounded guide wheel 65 of the fabric, while at the other end only therods 61 are connected and joined to each other, as therods 63 sustain acutting device 66 equipped, in this example, with ablade 67 designed to cut the tubular fabric according to a generatrix during its production. The blade may be substituted by other fixed or mobile (rotating) cutting devices. Therods hub 69, which contains a regulation device. The knitted fabric spreading device may be without thehub 69, as it is also possible to regulate each component manually rather than through centralized regulation. Theentire guide structure 60 is in fact suspended integral with a central shaft descending from the top part of the fixed structure of the machine. - The fabric is therefore cut open by the
blade 67 and laid in twolayers 59B, 59C (Fig.1) - joined to each other at the level of the generatrix passing through the vertex of the divaricator constituted by therollers 33A-35A (which coincides with thewheel 39 in the example). The layers are guided onto theinclined rollers single layer 59D, to be wound in aroll 70. - The
roll 70 rests on therubber end roller 57 and is wound on a piece-winding beam orroller 70A, the ends of which are guided in respective grooves approximately vertical or inclined, produced inside each upright 19, 21 of the piece-pullingdevice 11. - The
diverter rollers 31 are coated in rubber or another material with a high friction coefficient and are made to rotate by motion deriving from thepulley 15F and more precisely said motion deriving from themotorized roller 45 which in turn receives motion, in a manner known per se, from thepulley 15F. - For this purpose, keyed on the axle of the
roller 45, in proximity to theupright 21, is awheel 101 around which afirst chain 103 is driven to transmit the rotating motion of theroller 45 to afirst pinion 105 keyed on ashort axle 107. Theaxle 107 is connected, by means of auniversal joint 109, to a first end of ashaft 111 extending inside thebar 25 with a box-shaped structure. The opposite end of theshaft 111 is connected, by a seconduniversal joint 113, to anaxle 115 carried by thesupport 29 and onto which asecond pinion 117 is keyed. - A
second chain 119 driven around thesecond pinion 117, transmits motion from this to athird pinion 121. This third pinion is keyed on the axle of one of the twodiverter rollers 31, on which agearwheel 123 is also keyed. This gearwheel meshes with anidentical gearwheel 125, keyed on the axle of the other of the twodiverter rollers 31. - According to the layout described hereinbefore, when the circular machine and thus the piece-pulling device rotate around the vertical axis Z-Z, the rotatory movement transmitted, by means of the
pulley 15F, to thetraction roller 45, is transmitted to thediverter rollers 31, which rotate in opposite directions and in agreement with the direction of advance of the fabric which is in contact with them. Therollers 31, being coated in a material with a high friction coefficient, apply a traction force to thefabric 59A, reducing the traction that must be exerted on this by theroller 45 and therefore reducing deformations in the knitted fabric. - It is possible to modify the transmission ratio to the
rollers 31 by replacing one of the pinions of the kinematic chain and in particular thepinion 121, which is the most easily accessible. In this way it is also possible to modify the conditions of traction to which the fabric is subjected along its feed path. - Transmission of motion to the
rollers support 27, although the layout described is more advantageous as it creates smaller dimensions and difficulties in the zone to be accessed to change the piece of fabric. - Moreover, transmission of motion may also be provided with different mechanical systems to those illustrated in the specific embodiment, for example by means of a flexible shaft, by hydraulic motors operated by the rollers. In the mechanical transmission described, moreover, the joints at the ends of the
shaft 111 may be replaced with other means, such as pairs of bevel gears, that is with angular drives. - It is understood that the drawing shows merely an example provided purely as a practical demonstration of the invention, as the invention may vary in forms and layouts without however departing from the scope of the concept forming the invention. Any reference numerals provided in the attached claims are for the purpose of facilitating reading of the claims with reference to the description, and do not limit the scope of protection represented by the claims.
