Definitions
- the manufacture of yarns involves successive transformations which require, for their implementation, materials in which , starting from a generally fixed power source, the raw material from this source is passed through inside an appropriate processing assembly as a function of the transformations which it is desired to undergo, then, at the output of this set, we receive the treated material.
- the reception of the material is carried out for example in the form of coils, by accumulation inside a pot ...
- wire deliverers When passing inside the processing unit, it is imperative that the raw material scrolls at a constant speed and, to do this, in general upstream and downstream of said processing assembly, there are arranged wire deliverers very often consisting of assemblies comprising a driving cylinder against which a cylinder or pinch roller is pressed, the textile material passing between these two elements and being driven at a determined speed.
- wire processing equipment Most of the wire processing equipment marketed to date is in the form of assemblies comprising a plurality of identical working positions arranged side by side on a common frame, the processing members and in particular the wire deliverers and the transformation set between them being most often mounted one below the other, the wire deliverers being constituted essentially by shafts extending over the entire length of the machine, common to all of the working positions and on which come press the pressure rollers or rollers.
- the wire deliverers being constituted essentially by shafts extending over the entire length of the machine, common to all of the working positions and on which come press the pressure rollers or rollers.
- texturing machines by false twist, mills, or any other similar material.
- One of the problems when implementing such types of equipment is that of restarting a working position, for example when the take-up reel is full and must be replaced by an empty reel or when it is necessary to intervene on the machine during the manufacturing process, for example after a break in the wire.
- the invention also relates to any type of machine, of course comprising two wire deliverers between which is disposed a processing member or assembly other than a spindle of false twist by friction with crossed belts, provided however, as will be seen in the following description, that this treatment assembly allows (or is adapted to) that one can introduce the wire to be treated laterally by translation in the form of a strand stretched on either side of said element, and not axially by longitudinal traction.
- this treatment assembly allows (or is adapted to) that one can introduce the wire to be treated laterally by translation in the form of a strand stretched on either side of said element, and not axially by longitudinal traction.
- the heat treatment members such as the ovens, making it possible to carry out a shrinking or other treatment of the wire, air treatment nozzles, etc.
- processing block the assembly constituted by the two deliverers and the false twist spindle will be designated by the expression "processing block”.
- the invention therefore relates to an improvement made to machines enabling the production and processing of yarns (such as spinning machines, texturing by false twist or the like, etc.), machines which have a plurality of working positions. arranged side by side on a common support frame, each working position comprising, arranged between a wire supply source and an assembly for receiving the treated material (in the form of a coil for example), a processing block constituted of a processing member proper disposed between two deliverers each comprising a drive shaft against which a pressing roller is supported, the wire passing between these elements.
- the machine according to the invention is characterized, if we consider a working position seen from the front, in that the processing block is produced in such a way that: - the wire deliverers are of the driving roller and pressure roller type and are mounted orthogonally to the face of the machine, so that the material can be introduced between them laterally; the processing element proper (false twist pin for example) disposed between these deliverers is also designed so as to allow lateral introduction of the wire inside said element; the supply of the wire to be treated inside the first deliverer and its extraction at the outlet of the second is carried out in the opposite direction in a vertical or substantially vertical plane while its path in the treatment block is rectilinear and is in a horizontal or slightly inclined plane (called spinning plane); - an assembly for storing a reserve of yarn is arranged below the plane known as the "spinning plane", formed by the yarn inside the processing block and the generators passing through the input and outlet of said wire on the deliverers, said reserve and storage element being associated with a movable assembly allowing the introduction of the wire inside the
- each deliverer In each deliverer, one of the rollers is longer than the other, in order to facilitate the introduction of the wire between said rollers; the inlet of said rollers can also be bevelled so as to present a conical chamfer on its inlet edge;
- the reserve is constituted by an assembly in the form of a suction tube and which is associated with a mobile element, sliding inside said tube, thus making it possible not only to bring the wire inside the plane of work, but also facilitating the removal of the wire stored inside the reserve during its introduction into the different elements of the processing block.
- Such a type of machine is particularly suitable for a new type of launching method which is the subject of the present invention, said method of launching the wire either during a restart when replacing a full reel of wire treated with a tube. empty support, either during a recovery operation after breakage, essentially consisting of: - taking a length of previously formed wire from the winding reel (in the case where the machine is restarted by replacing a full reel with an empty support tube, the latter therefore comprising a few turns of previously formed wire); - to store the yarn thus taken from the spool inside the reserve arranged below the treatment plane between the first deliverer and the treatment organ proper, the path of the yarn from the winding spool to the entry of the reserve being made so that the portion of wire forms a loop surrounding the drive shafts of each deliverer of the processing block; to introduce the portion of wire stretched between the two drive shafts, practically instantaneously inside each of the members, this introduction being carried out with the wire running with its processing speed, starting by placing the wire in reserve in contact between the drive roller and
- the removal of the wire from the winding reel can be carried out by means of a gun which the operator moves to surround the drive rollers and bring the wire to the entry of the reserve.
- a machine and such a process can be easily automated either, by providing on each position of the machine a so-called "spacer" assembly enabling the wire in the form of a loop to be placed around the deliverers, or by providing such a spacer element on a robot , movable in front of the machine, and common to all working positions.
- Figure 1 illustrates schematically perspective view, a working position of a machine in which a wire (1) from a power source (2) must be, after having undergone a possible transformation in an area (3) not shown (drawing operation for example), subjected to a treatment inside an assembly, designated by the general reference (4) and which, in the present case, consists of a false twist spindle with crossed belts (5) arranged between two wire feeders (6,7) to then be returned in the form of a reel (8).
- the wire feeders (6,7) are of the type with motor rollers (6a, 7a) and pressure rollers (6b, 7b), the pressure rollers can be either mounted idly on the motor rollers , or on the contrary be also driven positively in rotation.
- These deliverers (6,7) are mounted orthogonally to the face of the machine, so that the wire (1) can be introduced between them laterally.
- the processing element in this case consisting of a false twist spindle with crossed belts which is arranged between these deliverers (6,7), is also designed so as to allow lateral introduction of the wire.
- a false twist spindle with crossed belts of the type which is the subject of French patent 2,619,831 (corresponding to US Pat. No. 4,910,953) in the name of the Applicant will advantageously be used.
- the supply of the wire to be treated (1) inside the first deliverer (6) and its extraction at the outlet of the second deliverer (7) are carried out in the opposite direction, in a plane vertical or substantially vertical, while the path of the wire (1) inside the processing block (4), a path which is rectilinear, is made in a plane, called the spinning plane, horizontal or slightly inclined, this plane P , known as the spinning plane, being formed by the plane passing through the wire inside the processing block (4) and by the generators (9a, 9b) passing through the input and output contact point wire on the drive rollers (6a) and (7a) of the two deliverers (6,7).
- a storage assembly (10) for reserving a length of wire is arranged below the above-mentioned plane P , this reserve essentially consisting of a suction tube and being associated with a movable assembly ( 11) called "launching jack", allowing the introduction of the wire inside the elements forming the processing block (4) and, simultaneously, the extraction of the wire stored inside said reserve (10).
- This mobile element (11) consists of a suction tube which slides inside the inlet end of the reserve (10).
- FIGS. 6a to 6l Such a recovery process illustrated by FIGS. 6a to 6l is the following.
- the spool (8) After stopping the position, the spool (8), whatever its diameter, is raised a few millimeters above its engine cylinder (12) (see Figure 4) as quickly as possible in order to avoid "d 'bury' the end of the wire in the spool.
- the control assembly (cam) (13) and the engine cylinder (12) can continue to operate.
- the wire feeders (6,7) are also stopped, the spindle (5), the two belts (5a) (upper belt) and (5b) (lower belt) of said spindle (5), being separated l one of the other.
- the pressure rollers (6b, 7b) of the deliverers (6,7) remain in contact with the drive rollers (6a, 7a).
- the full reel (8) is first evacuated, and a reel filled with a few meters of material is placed between the forks of the winding system. wire.
- the removal of the wire from the spool (8) can be facilitated by applying against the surface of said spool a motor element (15) (see Figure 4) allowing it to rotate in the opposite direction from its normal direction of winding.
- the wire being introduced inside the reserve (FIG. 6b) by means of a set of spacers (E1, E2), the portion of wire between the end of the launching cylinder (11) and the coil (8) (sequence illustrated in Figures 6c, 6d, 6e).
- a wire guide element (20) is preferably arranged between the take-up reel (8) and the deliverer outlet (7).
- the spacer devices E1, E2 therefore bring the wire in the form of a stretched strand in position E′1, E′2 (FIG. 3b or 6e), and this so that one comes to form a loop of wire.
- the launching cylinder (11) is caused to recede, which initially produces a translation of the wire on the shaft (6a) (FIG. 6g).
- the wire begins by being introduced inside the first delivery device (6), which causes a displacement of the portion of the wire held between the two trees in the form of a variable pitch helix with an exponential movement of the thread, allowing an almost instantaneous introduction of the stretched thread portion inside the assemblies of the bodies of the spinning block, this introduction being carried out starting with the first deliverer (6) then, almost instantaneously, inside the processing unit proper (5) and the second deliverer (7).
- the introduction inside the spindle is facilitated by associating with the latter a ramp (21) positioned so that the wire during its movement, comes into contact with the belt (5a) of said spindle which facilitates transverse movement.
- the end of the wire (1) (see FIG. 61) to be treated is connected to a portion of the wire placed in reserve during its passage around the roller (6a).
- the spindle (5) can then be closed and the pressure roller (6b) which had been previously removed from the drive roller (6a) is then re-engaged for operation normal.
- Such a machine design therefore makes it possible to carry out the recovery quickly, precisely, at high speed and this, in a completely automated manner, and may also be suitable for equipment making it possible to process fibers (for example spinning equipment using false twist spindles or any other similar material) than with continuous filament processing materials such as texturing machines, in particular by false twist, the oven associated with the spindle in front, as said above, be designed to allow introduction of the wire to be treated laterally by translation in the form of a stretched strand.
- fibers for example spinning equipment using false twist spindles or any other similar material
- continuous filament processing materials such as texturing machines, in particular by false twist
- the oven associated with the spindle in front as said above, be designed to allow introduction of the wire to be treated laterally by translation in the form of a stretched strand.
