Definitions

  • a short standstill time or reduction of the same is achieved in that, on the one hand, the bringing of the yarn to the 'knotter takes place with as large a speed as possible in dependence upon the yarn quality and, on the other hand, for an eventual required delivery bobbin-exchange a new delivery bobbin is always located in its preparatory or ready position.
  • a long waiting or idle time can also be prevented in that the determination for a standing idle winding station whether only yarn rupture must be remedied or, however, a delivery bobbin-exchange is to be undertaken, is already undertaken before such winding location is situated opposite the yarn rupture removal and delivery bobbin-exchange apparatus.
  • Such an apparatus is disclosed in the commonly assigned, co-pending United States patent application Ser. No. 360,226, filed Apr. 16, 1964, now United States Patent 3,304,015 gran-ted Feb. -14, 1967, invented by Rudolf Jenny and entitled, Method and Apparatus for the Processing of Undesired Yarn Conditions Appearing at an Automatic Winding Machine.
  • the therein disclosed apparatus is constructed such that feelers monitor or supervise the yarn travel at a winding station as well as also the available quantity or volume of yarn at the delivery cop. Upon interruption of the yarn travel at a given winding station the feelers respond and influence appropriate signal storage elements, such as impact means, through the intermediary of a lever system for instance, with such impact means being associated with the winding station. Upon proper operable positioning of the associated Winding station with respect to the tending apparatus or automatic for removing the disturbance or undesired yarn condition these elements are scanned, whereby immediately the appropriate work cycle is initiated in accordance with the encountered condition.
  • appropriate signal storage elements such as impact means
  • the standstill time of the table is then at least as long as is necessary for the apparatus to determine at a report-back or feedback path for example, that this disturbance is not capable of being corrected and, as the case may be, has delivered a signal allowing for continuation of the rotation of the table.
  • the other winding stations which in the meantime pos- *sibly exhibit an undesired yarn condition must, therefore, wait for a relatively long time for the removal of thei disturbance i.e. undesired yarn condition which, for example, is only manifested by yarn rupture which can be remedied.
  • Another very important object of the present invention relates to the provision of an improved method and apparatus for increasing the efficiency of automatic winding machines.
  • Still a further important object of the present invention relates to an improved control apparatus for winding machines which enables blocking of the stopping mechanism for the rotatable table in its ineil'ectual position for those winding stations which require a new delivery co'p for removing their undesired yarn condition as soon as appropriate scanning or testing mem ers have determined that no new delivery cops are available in the supply magazine, in order that the remaining winding stations which still have suiiicient yarn upon their delive y cop and only require a xnotting operation can be unobstructively serviced without any delay in time by the automatic provided for removing undesired yarn conditions.
  • the inventive control mechanism is characterized by the features that monitor means are associated with supply magazine for delivery bobbins in order to determine the availability of a delivery cop or bobbin in the delivery position thereof. Additionally, switch means for the control mechanism are operatively associated with the monitor means in order to prevent interruption of the relative movement between the relevant Winding station and automatic in the predetermined relative position in spite of exhaustion of the delivery cop of the associated winding station when the monitor means has not ascertained that there is a new delivery cop in the delivery or infeed position.
  • This control apparatus thereby serves to lock or render inoperable the table stop mechanism in the event there are not present any new delivery cops and renders it possible that the tending apparatus or automatic for rectifying yarn rupture only still has servicing requirements placed upon it from such winding locations in which the availabie yarn package upon the deiivery cop permits of a knotting operation, or such is justifiable.
  • he inventive method for continually supervising a number of winding stations by means of a monitor or supervising mechanism which scans such winding stations is characterized by the features that, when a delivery bobbin or cop is not available in a predetermined supply position a signal is removed and is evaluated as significant information to cause continuation of the scanning of other winding locations or stations in the event that the undesired yarn condition appearin at a given winding sta ion and which is to be remedied requires a new delivery cop.
  • FZGURE 1 is a perspective view of an automatic wind-- ing machine
  • FIGURE 2 is a perspective view of the bobbin magazine and the indexing or switching mechanism
  • FIGURE 3 schematically illustrates a portion of the winding machine
  • FIGURE 4 is a front view, somewhat on an enlarged scale, of a detail of the winding machine depicted in FEGURE 3;
  • FIGURE 5 is an electric circuit diagram of the control mechanism.
  • FIG- URE 1 wherein an automatic winding machine is schematically illustrated, it will be seen that such generally comprises, in its essential components, a stationary machine base A, a plurality of winding stations or locations B arranged at a rotating or revolving circular table or turret D, and a machine component defining an automatic or tending apparatus C arranged directly outside of the substantially circular path of travel of the aforesaid winding stations B.
  • This automatic C incorporates the mechanical and electric switching components necessary for removal of the faulty yarn condition or disturbance as well as the actual physical elements for removing such disturbance.
  • this automatic unit or tending mechanism C upon yarn rupture or depletion is switched-in so as to either remedy such yarn rupture or to conduct a new full delivery cop or bobbin 2 from a supply magazine 1 to the relevant winding location B and to then knot the yarn ends.
  • Automatic mechanisms C of the aforenoted type and suitable for implementing such operations are well known to the art. However, since the invention is not specifically related to details thereof, particularly the knotting operation, only enough of its structure and operation will be considered in the description to follow in order to make the general principles of this invention clearly understandable.
  • the yarn F travels from a delivery bobbin or cop 2a through a balloon breaker 5:; simultaneously equipped with a teeter element (not shown) for determining the presence of the yarn P, such fceler element for instance corresponding to that of the aforementioned C o-pending United States application, Ser. No. 360,- 226.
  • This feeler element is operatively associated in any suitable manner with an electromagnet 13b such that when the yarn is missing the armature 18a thereof moves as a stop into the operating zone of a switch 38.
  • the yarn F travels through a yarn rupturc feeler 51 which, when yarn rupture occurs, permits movement of the armature 19a of the electromagnet 191) into the operating zone of a switch 19, in that the electromagnet 1% has current applied thereto. Since the exact manner in which the feeler of the balloon breaker 50 and the yarn rupture feeler 51 are operably associated with the c "trornagnets 18b and 191'), respectively, are not consilercd important for understanding the invention and since such can be performed in any number of possible ways which will suggest themselves to those versed in the art, no further details are here given.
  • FIGURE 2 there is illustrated in simplified manner the switching or indexing mechanism for performing a step-by-step indexing of the bobbin supply magazine 1 having the delivery bobbins or cops 2 located in individual boxes or compartments 2b.
  • An indexing or switching dog or lever 3 and a cam piece 4 are secured to a bolt or shaft 5 which, in turn, is rotatably mounted at an arm 6.
  • This arm d has imparted to it a reciprocating movement via a cam plate 9 through the agency of a cooperating rod 7, with the number of strokes per revolution corresponding to the number of cam surfaces 8 located upon this cam plate 9.
  • such number of strokes per unit time is also determined by the rotational speed of a drive motor 18 operatively connected with a shaft 27 carrying the cam disk 9.
  • lever arm 12 via the cam piece 4 and the bolt 5 prevents a tension spring i from bringing the indexing dog or lever 3 into the zone of an indexing bolt 13 secured to the bobbin supply magazine 1.
  • the lever arm 12 provided with the roller 12:: is, in turn, prevented from performing a rotational movement via a shaft 15' and an arm 16 bearing against an impact surface or stop means 17.
  • a further supervising or monitoring element here in the form of a fioor flap or trap door 33, is rockably mounted upon a bolt 34%- at the delivery cop receiver or bin 39.
  • a pin 35 is secured to the aforesaid floor flap 33 which is downwardly pressed by means of a torsion spring 35 located in a recess 37 of a lever or pawl 38, and thereby holds the floor flap 33 in its closed position, shown in full lines in FIGURE 4 (position III).
  • the electromagnet 45 rocks the lever 4-6 and thereby frees the arm 16 from the stop means 17, whereby the rotating shaft 27 of the automatic together with the cam 47 via the rod 48 rotates the arm 16, the shaft and the lever arm 12 with its roller 12a and thereby frees the switching lever or pawl 3.
  • the switching lever 3 then indexes the bobbin magazine 1 for such length of time until a delivery cop 2 falls into the chute 49 and due to the weight of the cop brings the floor flap or trap door 33 from the empty position III into the full position IV, corresponding to the displacement path of the pin in the recess 37.
  • the cam portion 44 now releases the lever 41, whereby the switch 43 interrupts the electromagnet 45.
  • the lever or pawl 3 is again disengaged and brought out of the zone of the indexing bolt 13 for the bobbin magazine I.
  • the circuit arrangement of FIGURE 5 is designed to control three different possibilities for removal of a disturbance or faulty yarn condition, namely:
  • Group I-Switches the position of which (open or closed) are determined by the supervising or monitoring elements, that is from the side of the winding machine.
  • Group 1VAnalogous to Group III incorporates relay or magnetic coil 54 and contacts 54a to 540, whereby such relay 54 is provided with a timedelay device 54.
  • the yarn rupture feeler 51 which can be either mechanical or electrical for example, initiates application of current to the electromagnet 1%, whereby the armature 1911 thereof springs as a stop into the operating zone of the switch 1? and closes such (Group I).
  • the switch 19 is mounted ahead of the disturbance removal automatic C if considered with respect to the revolving motion of the winding location B, so that the winding location at which the disturbance is to be removed can be stopped with respect to the automatic C.
  • the closed switch 19 applies current to the coil of the relay 23 (Group 11), whereby the associated contacts (Group III) move to the right.
  • the contact 23a is opened, the relay or magnetic switch 55 of the drive motor M for the table D without current and thereby this drive motor M brought to standstill.
  • the contact 2312 opens and shuts-off the electromagnet 56.
  • the index bolt 57 is pushed via the spring 58 into the bore 59 of the revolving table D, whereby the exact arresting position of the winding location B in front of the automatic or tending mechanism C is guaranteed.
  • a switch 60 is arranged above the bore 59 which is closed by the index bolt 57 piercingly extending through the bore 59.
  • the relay or magnetic switch 55 could also switch over the motor M to a slow operating speed, whereafter the stopping would be effected by means of a contact of the switch 69.
  • the closing of the contact 6d (Group I) switches-in an electromagnetic coupling 61 which operatively connects a shaft e2 with the continuously revolving shaft 27 driven by the drive motor 16.
  • the coupling 61 is constructed such that the shaft 62 only executes a complete rev0lu tion through 360.
  • the non-illustrated cam disks which actuate the elements for removing yarn rupture in known manner.
  • a cam disk 63 (Group I) is seated upon the shaft 62 which, after completion of the knotting operation, opens the switch 64 and thereby deenergizes the relay 23.
  • the contacts of Group III move to the left, the magnetic switch 55 again switches-in the drive motor M, the energized electromagnet 56 pulls the index bolt 57 out of the bore 59 and thereby opens the switch 60. Consequently, the starting position, that is, the normal winding operation position is again provided.
  • the contact 23c serves as a self-holding contact of the relay 23.
  • the switch (contact) 54-] serves as a self-holding contact for the relay 54, the contact 54c switches-in the magnetic coupling 25 and connects the shaft 28 with the shaft 2'7 in such a manner that the shaft 27 only executes a complete revolution through 360.
  • the cam disk 29 is seated upon the shaft 28 which carries out the exchange of the delivery cop as depicted in FIGURES 2 and 3 already previously explained. The return to the normal winding operation takes place as explained under section (a) by means of the cam disk 63 and the switch 64. It is to be understood that if yarn rupture occurs beneath the balloon breaker such condition will be treated as an exhausted delivery cop since the knottcr cannot operate in this zone and, thus, a bobbin-exchange will be initiated.
  • a timeswitch out relay (not shown) can be arranged in the current circuit of the electromagnet 45 which, for example, after a revolution of the magazine switches out the indexing mechanism for the bobbin Suppl magazine 1 (FIGURE 1).
  • Method for the continuous supervision of a number of winding stations by means of a monitoring mechanism for scanning such winding stations wherein each said winding station carries out a relative movement with respect to a tending apparatus at which any given winding station could normally stop in order to correct a faulty yarn condition which may appear at said given winding station, comprising the steps of: testing for the presence of a delivery cop in a predetermined common supply position for said number of winding stations, deriving a signal when a delivery cop is not present at said common predetermined supply position, and employing said derived signal to cause any given winding station at which a faulty yarn condition has occurred which would require replacement of its delivery cop to fail to halt at said tending apparatus inasmuch as no delivery cop is available at said predetermined supply position which could be used for replacement purposes.
  • Method for increasing the etliciency of automatic winding machines including the step or arresting said given winding station at said tending apparatus if it is determined that the faulty yarn condition is yarn rupture which can be corrected by a knotting operation.
