' The present invention relates to a thread guide driving arrangement for use with artificial silk spinning machines of any suitable kind, that is, Spinning machines operating on the principle of bobbin winding or cake generating by action of centrifugal force.
It is generally known that the influence of the thread guides which operate to control the winding of bobbins or the formation of cakes of artificial silk filaments emanating from the spinning nozzles is of decisive significance for the uniformityof the finished artificial silk package. The effect of the thread guides is accordingly markedly felt in the subsequent handling of the filaments, when these are wound on bobbins or formed into cakes in centrifugal (Topham) boxes.
The most reliable proof of correct working of a thread guide consists in the manner in which the guide reverses from one direction into the other, that is to say, each time the thread guide reaches one of the two ends of traversing movemerit and starts onits reverse movement. Dependent upon whether the thread guide changes its direction of traversing too rapidly or too slowly, the physical character of the filaments is likely to be altered or uneven distribution of the bearing surfaces of the thread package may result, which renders unwinding more difficult and causeslosses of manufacturing.
Several remedies have already been proposed in order to obtain maximum uniformity of working" of the thread guides. To this end, for instance, heart shaped eccentrics have been resorted to, whereby the backward and forward movement of the thread guides is positively controlled. These heart shaped eccentrics have however several disadvantages, as it is almost impossible to adjust the cusp of the heart form exactly into alinement with the tip thereof, so that the two ends of the bobbin winding are not supplied with exactlythe same number of thread windings. Further, the guide roller is liable to jump across the 'tip of the heart form, so that for a certain time the prescribed curve is not followed, in consequencewhereof, a material amount of driving energy is squandered in passing across the tip as well as the cusp of the heart form.
If the unwinding is effected at a relatively high speed, it may happen that the heart shaped eccentric causes vibrations which have a detrimental influence on the spinning process. A further disadvantage of these thread guide drives is the liability of disuniformity of guidance of the threads ensuing at both points of reversal, there by to cause the winding at both ends of the bobbins to become uneven, and to form knots or bulges.
With an arrangement accordin to the present invention, these disadvantages are intended to be avoided in that the thread guides operate in conjunction with the piston of a hydraulic telemetric system, whereby the length of the piston travel can be utilised, by means of a cam, for producing the desired form of bobbin.
In the accompanying drawing an embodiment of the invention is shown, by way of example only, in the form of a driving arrangement as applied to a spinning machine.
Each pair of bobbins I is mounted on a winding spindle 2 and all these spindles 2 are connected by means of screw gears 3 and 5 with driving shafts d and 6 respectively. The driving shaft 4 serves for driving the winding spindles 2 in one direction of rotation, and the driving shaft 6 for driving the shafts 2 in the other direction of rotation, the winding spindles 2 being driven by means of a coupling (not shown) either by the shaft 4 or the shaft 6.
On the driving shafts 4 and 6 are mounted spur gears 7 and 8 which are driven by means not shown on the drawing. A gear pump [4 is driven by bevel wheels 9 and I 0, a shaft H and back gears I2 and. I3. This pump is connected with so as to be compelled to move together.
a suction pipe l5 and a pressure pipe IS. The suction pipe l5 dips into a pressure-agent reservoir l1 and the supply or pressure conduit l6 leads to a piston control valve i 8. Included in a conduit branching from the pressure pipe I6 is a safety valve [9 which holds the pressure in the main or supply conduit 16 constant. In another branch conduit is included a cock valve 20 which serves for regulating the pressure-agent pressure in the main conduit l6. In the piston control valve I8 is contained a double piston 2| which is carried by a piston rod 22. Further, two return pipes 23 and two connecting pipes 24 and 25 are connected with the piston control valve [8 which lead to an actuating cylinder 26 the piston 2! of which is arranged on a piston rod 28 the portion of the latter projecting out of the cylinder extending the entire length of the machine.
To this piston rod are connected transmission cables 29 by means of one of their ends so as to pass oversheaves 30, the other cable ends being secured to a thread guide carrier rod 3 I Further cables 32 are secured at one of their ends by means of a spring 33 to the piston rod 28, and are passed over sheaves 34 and secured at their other ends to a second thread guide carried rod 35. ,Both thread guide carrier rods 3| and 35, on which thread guides 36 are arranged, are rigidly connected to each other by cross rods 31, y virtue of the springs 33 intermittent movement transmission is avoided.
A guide member 38 which is fitted to the piston it rod28 receives a guide rod 39 in axially displaceable relation thereto. One endoi this guide rod is in form of a fork 45 the divergent arms of which cooperate with a control member it which is arranged on the control piston rod 22. The other end of the guide rod 35! is connected to a lug which is displaceably guided in a rotatable stirrup 4'3. On the axle i l of the rotatable stirrup i3 a lever arm i is fixed to the free end of which a rod 46 is pivoted. This rod 55 is connected by means of a socket-joint A? with another rod 48 in such a manner that by turning the sleeve ll the rods 55 and 48 can be forced against each other. The rod 48 is provided at its bottom end with a roller 59 which by action of a pressure spring 55 which surrounds said rod, is pressed against a cam 55, the latter being mov" ably. arranged on a shaft 52. The cam can be connected with this shaft 52 by the of a coupling sleeve 53.
The drive of the shaft 52 is eiiected by means of a driving arrangement (not shown on the drawing) through the medium of the gear wheels 55 and 55.
The manner of operation of the arrangement described is as follows:
By means of a drive (not shown) the winding spindles 2 are driven in unison with the bobbins I via either of the spur gears l or ii, the she. s l or 5 and the screw gears 3 or 5. At the 5 me time the gear pump it is driven from the shaft Ii. By this means the pressure-agent is conveyed through conduit it into the control cylinder i8 whence, dependent upon the setting of the control piston 2i, it passes either through conduit 24 on the left hand side or through conduit 25 on the right hand side 01" the actuating piston 2? into the cylinder 25. Consequently, the actuating piston 23 is forced together with the piston rod 28 to the right or left hand side of the figure or" the drawing by the pressure of the pressure-agent.
If the piston rod 28 is pushed to the right, the thread guide car "ier rods 3! and 35 are moved in the downward direction by action of the cable 25, whereas. if the piston rod 2.8 is pushed to the left the thread guide carrier rods are moved action of the cable 32 in the upward direction. At the end of each stretch of travel of the piston one or the other of the two arms of the fork 45 cooperates with the control member ii on the control piston rod 22, whereby the control piston 2! is moved in that direction, due to which the pressure-agent is changed over to the other side of the pressure piston 2'5. By this means, the piston rod 28 is moved in the opposite direction until the fork 40 cooperates with the control member it so as to change over the, control piston anew.
By the action of the cam 5i through the rods i8 and E5 the lever arm or crank 45 is displaced so that the rotatable stirrup i3 is also displaced through the shaft i l. Due to this, the rod 3& received in the guide member 33 shifted, whereupon the fork ii} cooperates with the control member ii upon a longer or shorter travel of the piston 2i so that the changing over thus takes place upon a shorter or longer travel of the piston 27. In this manner the length of the piston travel and consequently also the the bobbin can be controlled by means of the cam 55.
