It is well known that in winding yarn with a textile machine, whereby yarn or fibers are wound, such as spinning machines, fly frames, twisters, and drawing machines, various types of wound-up packages are produced by altering the traverse position and traverse length in the traverse device in the course of the package winding. As one of the traverse devices to control traverse mode is known a device whereby a pair of controlling plates connected to a piston which gives a traverse bar up-and-down motion and a pair of controlling plates which alter their positions according to the progress of traversing motion between the pair of controlling plates, engage with each other to alter the traverse position-and/or traverse length.
However, in such a traverse device the mode of traverse is mechanically controlled, and so there is naturally a limitation to possible traverse modes and it has a drawback that the structure is generally involved and complicated.
Further it is desirable that to alter the shape of the wound package according to the type, size, amount of wound yarn, the mode of traverse in the traverse device be altered. In these well-known traverse devices, such operations for alteration are very troublesome and many parts must be replaced to alter the traverse mode.
Further it is very often desired in package winding that on the same bobbin or a plurality of bobbins or spools on the same spindle, different typesof traversing operations spaced from each other be .carried out to form a plurality of winding parts or sections spaced from each other.
For instance, it is essential that in processing and winding yarn with draw-twisters, ring twisters, etc., initially wound yarns, which are inconsistent in the number of twist and other properties at the time of string-up or the beginning of package winding, be removed from the winding section for normal yarn and wound separately.
For this reason, these preliminary windings have been wound on a waste spool or a preliminary winding section of a bobbin via travellers set to the traverse ring positioned lower than the normal yarn winding section, and after the yarn becomes normal and uniform, the traverse ring is pushed up manually or automatically to the normal yarn winding section of the bobbin to allow normal package winding.
However, in the prior art it is difficult to carry out traversing motions of the preliminary windings and to prevent sloughing at the winding section for the preliminary windings. I t
It is the object of this invention to provide a traverse device for a package winding apparatus whereby the mode of traverse is controlled by the relative movement of a pattern member and a photoelectric system interlocking with said traversing mechanism such that the traverse mode, that is, the shape of the wound package is easily and optionally formed.
It is another object of the present invention to provide a traverse device whereby the mode of traverse is easily altered only by a change in pattern plates.
It is further another object of the present invention to provide a traverse device whereby it is possible to carry out a plurality of traversing operations and to form a plurality of sloughless winding sections spaced from each other.
It is a further object of the present invention to provide a package winding apparatus which accelerates the number of revolutions of a spindle at the beginning of winding and decelerates it at the end of winding relative to the mode of traverse.
The present invention relates to a traverse device for a package winding apparatus comprising a cylinder provided with a piston capable of making reciprocating motions by fluid pressure, a traversing mechanism actuated by the reciprocating motions of said piston, a change over valve for changing the running direction of the fluid fed to the cylinder, a photoelectric system consisting of a light source and a light-receiving mechanism, a pattern member determining traverse length adapted to cross the light paths of the photoelectric system, an oscillating mechanism to permit said pattern member or said photo-electric system to make reciprocating motions, interlocking with said piston, and a driving mechanism to give reciprocating motions to the pattern member attached to said oscillating mechanism movable in a direction intersecting the piston reciprocating direction at right angles or to the photoelectric system whereby said change-over valve is actuated by a signal caused to generated at the edge of the pattern member in the photoelectric system by the relative motion between the pattern member and the photo-electric system.

In FIG. 1 pressure fluid supplied from conduit (1) is passed through either conduit 3 or 4 by actuating an electro-magnetic valve 2 and is selectively fed into both sides of piston 6 of cylinder 5. When solenoid A of electromegnetic valve 2 is excited, pressure fluid supplied from conduit 1 is fed into the left-hand side of cylinder 5 via conduit 4 to move piston 6 in the right direction, whereas when solenoid B of electromagnetic valve 2 is excited, pressure fluid supplied from conduit 1 is fed into the right-hand side of cylinder 5 via conduit 3 to move piston 6 in the left-hand direction. The fluid in cylinder 5 present in piston reciprocating direction is discharged into storage tank 1 via pipe 3 or 4 and electromagnetic valve 2.
To said piston 6 is connected piston rod 8 andto piston rod 8 is connected traverse bar 7 through a joint. The reciprocating motions of piston 6 are transmitted to the traverse bar 7. The traverse bar 7 gives pulley 8' reciprocating rotary motion to impart up-and-down motion to a ring rail 7' hung by belt 8" from pulley 8" disposed concentrically with pulley 8'. To the ring rail 7 are attached rings. The yarn is wound on bobbin 33 via traveller 42 mounted on the ring while making traversing motions according to that of the ring rail 7 that is, that of the piston rod.
The combination of cylinder 5 provided with piston 6 capable of making reciprocating motions by fluid pressure, traverse bar 7 actuated by reciprocating motion of piston 6, and a change-over for reversing the direction of the fluid fed into the cylinder 5 is well known in a yarn traverse device.
In the present invention, a photoelectric system comprising a light source and light-receiving mechanism and a pattern member for determining traverse position and traverse length are arranged in a relative position such that light paths in the photoelectric system are intercepted by the pattern member and that either the pattern member or the photoelectric system makes reciprocating motions while interlocking with the piston and linear motion at right angles to the piston running direction. For this purpose, to an oscillating mechanism making reciprocating motion while interlocking with the piston is mounted a pattern member or a photoelectric system in a direction intersecting at right angles the piston running direction and a driving mechanism for giving reciprocating motion to the pattern member or the photoelectric system.
The pattern member consists preferably of a pattern holder and a pattern plate or plates attached thereto. By replacing a pattern plate, one can easily change the mode of traverse.
In FIG. 1 the oscillating mechanism and driving mechanism consist of two shafts l2 and 13 attached to frame 11 of the machine, bracket for holding the pattern member being slidably attached to shafts l2 and 13, worm 22 slidably mounted to shaft 13 and rotatably attached to it according to its rotation, screwed shaft 16 rotatably attached to pattern member bracket 10, worm wheel 21 meshing with worm 22, attached to the tip of the screwed shaft 16, and pattern member 17 and 18 meshing with shaft 16 and movable up and down according to the revolutions thereof.
In FIG. 1, to rod 9 connected with piston rod 8 is fixed pattern member bracket 10. This bracket is slidably movable to the left and right through slide bearings 14 and 15 over shafts 12 and 13 fixed to frame 11 of the machine. To bracket 10 is attached screwed shaft 16 at right angles thereto. Pattern holder 17 having a screw meshing with screwed shaft 16 is adapted to move up-and-down along screwed shaft 16, but does not rotate therewith. To the pattern holder 17 is fixed pattern plate 18 of any shape. Photoelectric system consisting of light source and light-receiving mechanism 20 with pattern plate 18 interposed therebetween is disposed in a direction perpendicular to the face of pattern plate 18. The light source behind the plate is not shown. The light-receiving mechanism may be photoelectric cells, photomultipliers, phototransistors, etc. Screwed shaft 16 has worm wheel 21 attached to its lower tip and is rotated by being worm 22 attached to shaft 13. Shaft 13 is rotated by motor 23 through gears 24 and 25.
Pattern plate 18 serves the purpose of intercepting the light from the light source entering light-receiving mechanism 20. Suppose piston 6 moves from left to right to make pattern plate 18 move from left to right. When the left-handedge of pattern plate 18 reaches a line connecting the light source and photoelectric cell 20, light enters photoelectric cell 20 and solenoid B is excited to move piston 6 and pattern plate 18 from right to left. During this movement, photoelectric cell 20 is intercepted by pattern plate 18 until the righthand edge 29 of pattern plate 18 reaches a line connecting the light source and photoelectric cell 20. The cell receives light again and solenoid A is excited to permit piston 6 and pattern plate 18 to move from left to right. By the repetition of such motions, traverse bar 7 is caused to make traversing motions.
On the other hand, pattern holder 17 and pattern plate 18 are caused to move upwardly perpendicular to the oscillating direction of the bracket, independently of the above-mentioned traversing motions, by screwed shaft 16 rotated by motor 23 through gears 24 and 25, driving shaft 13, worm 22 and worm wheel 21. Therefore, traverse length and position vary with the contours of edges 28 and 29 of pattern plate 18.
When a bobbin is full, driving shaft 13 is reversely rotated at high speeds by a known reversing mechanism. Screwed shaft 16 is thus reversely rotated and pattern plate 18 and pattern holder 17 are returned to the traverse starting point.
In the present invention, an electric circuit such that electromagnetic valve 2 is operated by the photoelectric system is obvious to one skilled in the art.
Pattern plate 18 of any material such as translucent synthetic resin plates, metal plates, paper, etc. can be used.
Further in the above described embodiment, the pattern plate 18 was moved, and the photoelectric system was maintained stationary. However, the pattern plate, can be allowed to stand still and the photoelectric system may be caused to move as described above with regard to the pattern plate. In short, relative motions may be made between pattern plate 18 and photoelectric cell 20.
According to the apparatus of this invention, the mode of traverse in the traversing mechanism can accurately be controlled by the shapes of the edges of the pattern plate and the distances therebetween. Further by the selective choice of a pattern plate size and shape, traverse of any mode is possible and the build-up of a yarn package of any shape is obtainable. Moreover by an extremely simple procedure such as replacement of a pattern plate and change in speeds of relative motion between the pattern plate and the photoelectric cell, one can easily change the mode of traverse.
Pattern plate 18 mounted to pattern holder 17 may be of the various shapes as shown in FIGS. 3A to 6A. By use of the pattern plates in FIGS. 3A, 4A, and 6A, the modes of traverse in FIGS. 3B, 4B, and 6B and packages 34 of shapes as shown in FIGS. 3C, 4C, and 6C are obtained. Further by use of pattern plate 18 as shown in FIG. 5A and by means of driving shaft 13 being reversely rotated at specified intervals, the mode of traverse as shown in FIG. 5B and the build-up of the package in FIG. 5C are obtained. In this case, the reverse rotation of driving shaft 13 may be effected by disposing two photoelectric systems and preferably limit switches to determine the locality of the reciprocating motions at the top and bottom of the pattern member to actuate a reversible rotary mechanism attached to motor 23 by the signals from the photoelectric systems or limit switches.
In one embodiment of the present invention, the pat tern holder can support a plurality of pattern plates spaced from each other.
In FIG. 7, a plurality of pattern plates 18 and 19 are set to pattern holder 17 spaced from each other. In this diagram, common numerals for common elements with FIG. 1 are used to avoid overlapping.
Main pattern plate 18 for determining the build-up of normal yarn on a bobbin and sub-pattern plate 19 for determining the build-up of waste yarn are mounted to pattern holder 17. Photoelectric cell 20 is disposed where light is intercepted by either main pattern plate 18 or sub-pattern plate 19.
Main pattern plate 18 and sub-pattern plate 19 serve the purpose of intercepting a light from light source (not shown) entering photoelectric cell 20.
Now, as shown in FIG. 9, when at the start of winding, initially wound non-uniform yarn 31 is wound onto an off-standard yarn winding part such as waste spool 32, piston 6 is moved to the right and ring rail 7 with rings attached thereto is lowered to the position of waste spool 32. Pattern member bracket is thus transferred to the right and light to photoelectric cell is intercepted by sub-pattern 19. When piston 6 and sub-pattern 19 move from left to right and the left-hand edge of the latter reaches a line between vthe light source and photoelectric cell 20, light enters the photoelectric cell, solenoid B is excited, the piston moves from right to left, and the sub-pattern plate moves from right to left. During this movement light is intercepted from photoelectric cell 20. When the plate 19 moves to the left and right-hand edge 27 of sub-pattern plate 19 reaches a line between the light source and photoelectric cell 20, the cell receives light again to excite solenoid A. In like manner sub-pattern plate 19 moves from left to right together with piston 6. By the repetition of such motions, ring rail 7 is given traversing motions of small traverse length at the position of waste spool 32 as shown by A, in FIG. 8.
Thus preliminary windings are built on waste spool 32 in good order and if uniform yarn begins to appear, the excitement of solenoid A is stopped one time by sending an optional signal. As a result, regardless of photoelectric cell 20 receiving light at the right-hand edge of sub-pattern plate 19, piston 6 moves left and ring rail 7 also moves to the part 34 of bobbin 33 to wind regular yam as shown in FIG. 8. And at the same time pattern member bracket 10 moves left resulting in intercepting of light to photoelectric cell 20 by main pattern plate 18. In like manner as for sub-pattern plate 19, at both edges 28 and 29 of main pattern plate 18 photoelectric cell 20 receives light and solenoids A and B are excited to cause piston 6 to move and a reciprocating motion to be imparted to ring rail 7' thereby causing traversing motion for the regular building of a package. That is, in FIG. 8, traversing motions of A are changed into those of B When they move from A to 8,, a given length of transfer tail is wound on space A between the lower end of regular yarn winding bobbin 34 and the upper end of waste spool 32 as shown in FIG. 9. I
On the other hand, like sub-pattern plate 19, main pattern plate 18 makes up-and-down motions independently of the above traversing motions due to screwed shaft 16 being rotated by motor 23 through gears 24 and 25, driving shaft 13, worm 22, and worm wheel 21. Therefore, the traverse length varies according to the shapes of edges 28 and 29 of main pattern plate 18.
When the building of yarn is finished and a bobbin is full, the excitement of solenoid B is given one rest. Thus, when piston 6 moves right because the photoelectric cell receives light at left-hand edge 28 of main pattern plate 18, solenoid B is not excited. Accordingly, ring rail 7' goes down to waste spool 32 as shown in FIG. 9. And at the same time pattern member bracket 10 moves right, and main pattern plate 18 and sub-pattern plate 19 descent to permit sub-pattern plate 19 to intercept light from photoelectric cell 20. Thus while by the previously described procedure a small traverse length is obtained by sub-pattern plate 19, the apparatus stops. At thus time, while the yarn is allowed to stand on the apparatus, doffing is carried out by cutting off the yarn extending over waste spool 32 and bobbin 33 and an empty bobbin is replaced. AFter all the spindles have been filled with empty bobbins, the operation is started and the traversing motions of small traverse length as shown in FIG. 8 A are made until standard yarn has appeared to permit the preliminary windings to be wound onto waste spool 32 in good order. Thus a transfer tail is formed while ring rail 7' shifts to standard yarn winding portion 34 of the bobbin and traversing motions for standard yarn B are made. 7'
This process is repeated hereinafter.
According to the apparatus of the present invention, since the initially wound yarn on the waste spool is in good order by traversing motions without sloughing, the start-up of all the spindles for the building of packages can smoothly be accomplished and neither staining nor the breakage of the yarn occurs. Hence continuous operations are affectively possible until the waste spool is full and the apparatus greatly contributes to the enhancement of efficiency and increase in yields.
Further the shifting from the waste yarn winding portion to the standard yarn winding portion is mechanically and simultaneously carried out; and consequently, the length of a transfer tail and wind pitch become constant, resulting in the production of package easily reproducible in the subsequent processings.
In FIG. 7, to a pattern holder are attached main pattern plate 18 and sub-pattem plate 19 spaced from each other. Instead, a plurality of main pattern plates may be set to the pattern holder to build a plurality of yarn build-ups spaced from each other on the same bobbin.
The present invention provides a device comprising a cylinder provided with a piston capable of having a reciprocating action by fluid pressure, a traversing mechanism actuated by the reciprocating action of said piston, a changeover valve for changing over the feed direction of fluid to the cylinder, a photoelectric system consisting of a light source and a light-receiving mechanism, a pattern member for determining traverse length in the traversing mechanism, so arranged as to intercept the light paths of the photoelectric system, an oscillating mechanism to permit said pattern member or said photoelectric system to interlock with said piston, a driving mechanism to allow the pattern member or the photoelectric system to move up and down in a direction perpendicular to the piston running direction, a spindle holding a bobbin upon which yarn is wound for rotating the bobbin, a mechanism for driving the spindle and a control mechanism for controlling the number of rotations of the spindle driving mechanism whereby said control mechanism for the rotation of the spindle is driven with drive source common with the driving mechanism of the pattern member or the photoelectric system so as to synchronize with the up-and-down motions of said pattern member or photoelectric system.
In the device of the present invention, the combination of the spindle, spindle-driving mechanism and traversing mechanism described above in well-known. The control mechanism for spindle rotation driven by a driving source common with the driving mechanism for the pattern member or photoelectric system in the traverse device is so disposed as to synchronize with the mode of traverse formed by the relative motion between the pattern member and the photoelectric system and to control the number of rotations of the spindle.
In the device of this invention the oscillating mechanism and driving mechanism for forming the mode of traverse have been mentioned above. The control mechanism for spindle rotation consists preferably of a power transmission gear fitted to a driving shaft having a worm in the driving mechanism for the pattern member; a reduction gear driven through the power transmission mechanism; a cam driven through said reduction gear and a differential transformer provided with a core having a reciprocating action by the rotation of the cam.
In FIG. 10 (Parts common with those in FIG. 1 are expressed in common numerals), the construction and function of cylindrical mechanism, traverse mechanism, change-over valve, photoelectric system, pattern member, oscillating mechanism and patternmember-driving mechanism are identical with those of FIG. 1.
Cam 38 for controlling the speed of spindle rotation is given rotation from the left-hand edge of shaft 13 through gear train 36 and reduction gear 37. The displacement of core 40 of differential transformer 39 varies with rotation of cam 38. The output of differential transformer 39 is thus varied and by use of this signal the speed of rotation of driving motor 44 for the spindle is controlled. The control of speed of rotation of the driving motor 44 by use of the above-mentioned differential transformer 39 is well-known.
Pattern plate 18 ascends by the rotation of screwed shaft 16 while ring rail 7' makes traversing motions by the action of electromagnetic valve 2, piston 6, oscillating bracket 10, pattern member 18 and photoelectric cell 20. The speed of rotation of screwed shaft 16 is adjustable by the replacement of the change gear of feed gear train 24 for the pattern plate. Thus the traversing motions transmitted to ring rail 7' resemble the shape of pattern plate 18. Yarn 35 passes through guide 41 and ring 42 mounted on the ring rail 7' hanging from traverse bar 7 and is wound on bobbin 33 held on spindle 43 and rotated with spindle driving belt 45 while making traversing motions.
In the winding operations if the amount of the upand-down motion of pattern plate 18 for the time when a bobbin becomes full is rendered constant and the screw pitch of screwed shaft 16 is constant, the number of rotations of shaft 16, that is the number of rotations of shaft 13, will be constant and the rotational displacement of cam 38 for controlling the number of rotations of the spindle will always be constant. For instance, suppose when with a rotational displacement of cam 38 of 300 one bobbin becomes full, a control signal for the rotational speed of the spindle is given. If gear train 36 and reduction gear 37 are adjusted so that cam 38 is displaced through 300 by the number of rotations of shaft 13 in accordance with the amount of movement of the pattern plate, the rotational speed of the spindle can receive a similar control irrespective of the length of time when the bobbin becomes full. That is, the changes in the rotational speed of a spindle corresponding to a certain displacement of pattern plate 18 are constant if the shape of cam 38 is constant irrespective of form of the products and the drawing and take-up speeds.
Especially in warp winding wherein package diameter and the displacement of the pattern have an almost constant relation with each other, the relation between package diameter and the rotational speed of the spindle are always constant, and even when drawing and take-up speeds are altered, there is no need to alter the rate of variation of spindle rotational speed. This is very convenient for operations.
Hence in the device of the present invention, it is possible to wind yarn on a bobbin in an optional shape of package winding and to make operations easier by decreasing the number of rotations of the spindle with an increase in the build-up diameter of the yarn.
