Definitions

  • the invention relates to a shut-off mechanism for a coiling machine having at least one winding unit wherein the spool to be wound is journalled in a support which is movable relative to a driving drum, and where-in said driving drum contacts the spool at its circumference and drives it by friction.
  • the driving drum may be constructed in such winding machines for example as a grooved or slotted drum, the groove or slot being provided for guiding the thread toand-fro along the drum and accordingly along the spool.
  • alternative thread guiding means may be provided, which are separate from the driving drum.
  • a sensing member at each winding unit, which senses the spool in the process of being wound and which closes an electric switch e.g. a snap switch, as soon as the coil diameter has reached a predetermined magnitude, in order to initiate the shutting off operation.
  • Such switches have the disadvantage of not operating accurately enough as will be explained later in more detail.
  • a shut-off mechanism for a Winding machine having at least one winding unit, comprising in combination: a driving drum, a support movably mounted relative to said driving drum, a bobbin to be wound journalled in said support and being driven by said driving drum by frictional contact of its surface, a photoelectric cell device having a first member operatively connected with said support and movable in accordance with the relative movements of the latter with respect to said driving drum, and a second member adjustable along the path of movement of said first member, a lamp and a photoelectric cell being mounted in juxtaposition on said first member, a diaphragm having an aperture mounted on said second member between said lamp and said photoelectric cell, and a device disengaging the frictional contact between said driving drum and said bobbin or spool upon the latter attaining a predetermined coil diameter, said device being electrically connected with said photoelectric
  • FIGv l is a diagrammatic end elevation of a shut off mechanism
  • FIG. 2 is a side elevation of some parts of this mechanism as viewed in the direction of the arrow II of FIG. 1.
  • the mechanism illustrated serves for shutting-oft" the winding operation at one winding unit of a winding machine, whose main drive shaft is denoted 1.
  • a friction wheel 2 On the shaft 1 there is mounted a friction wheel 2, which by way of a friction wheel 3 drives a friction wheel 4, which is keyed on the same shaft 6 as a grooved drum 5.
  • the shaft 6 is journalled in a bracket 7, which is fixed to the ice machine frame (not shown). Adjacent the grooved drum 5, whose groove 8 runs helically in the usual manner, as shown in FIG.
  • a helical coil 9 in the process of being wound, whose spool sleeve (not shown) is journalled by means of two pivots 10 at the free ends of two parallel arms 11, which at their other ends are fixedly connected with one another and with a shaft 13.
  • the grooved drum 5 drives the bobbin or coil 9 by friction and at the same time guides the thread to be wound to-and-fro along the coil 9 by means of groove 8, so that a so-called wild coil is formed on coil 9.
  • the diameter of the bobbin 9 increases, and the spool support 11, 12 with the shaft 13 turns in bearing 15 fixed to the machine frame. It may be assumed, that the winding operation is to be shut-off, when the coil has attained the position and size indicated in FIG. 1 in chain-dotted lines. In this position the coil is denoted 9', and the arms are denoted 11.
  • a sector-shaped diaphragm 16 is mounted which has a radial slot 17 which is partly overlapped by a small plate 18.
  • the small plate 18 is mounted adjustably by means of two screws 19 on said diaphragm 16, so that the optically effective width of the slot 17 can be adjusted.
  • a U-shaped support 22 is mounted on a shaft 21 journalled in bearings fixed to the machine frame.
  • One leg 23 of said support 22 carries an electric lamp 24, in juxtaposition with which a photoelectric cell 26 is mounted on the other leg .25 thereof.
  • the diaphragm 16 extends between the said legs 23 and 25, so that a light beam from the lamp 24 can impinge on the photoelectric cell 26 only when the slot 17 clears its path.
  • the photoelectric cell 26 lies in the input circuit 27 of an amplifier 28, Whose output feeds a solenoid 29, whose armature is constructed as a plunger 30.
  • the plunger 30 is biased outwardly by a spring (not shown) arranged in the interior of the solenoid, and upon energizing said solenoid is pulled by the latter inwardly against the bias of said spring.
  • a transverse pin 31 is arranged, which extends into a hole or slot 32 provided at the free end of the angular operating lever 33 which in its longitudinal direction allows some play to the transverse pin 31.
  • the angular lever 33 is pivotally mounted on the shaft 6 and carries near the apex of its angle a pivot 34, on which the friction wheel 3 is journalled. When the solenoid 29 is deenergized the lever 33 is in the position shown in full lines, the friction wheel 3 con- 'tacting the friction wheels 2 and 4.
  • a pointer 35 is keyed, which by turning the shaft 21 can be adjusted on a diameter scale 36 fixed to the machine frame to a magnitude desired.
  • a crank 37 is provided, which is keyed to a shaft 38 carrying a worm 39. This worm 39 meshes with a worm wheel 40, which is mounted on the shaft 21.
  • the components 37-44 which are omitted in FIG. 1 for simplicitys sake, may obviously be replaced by any other adjustment mechanism for the pointer 35 and support 22, respectively.
  • shut-oif device described has considerable advantages over those shut-off devices wherein a feeler is provided which senses the bobbin or spool 9 in the process of being wound, and which closes an electrical switch when the spool has reached a predetermined diameter. Since the diameter of the spool increases gradually, the distance of the two contact pieces of the switch diminishes only graduallyunless special measures are takenso that no accurate switching moment is defined. Moreover the contact pieces are rapidly destroyed by arcing.
  • a sector-shaped diaphragm is attached on a pivotal spool support in a particularly convenient manner, this is by no means indispensable.
  • the bobbin support may be guided parallel to itself instead of being pivotally mounted, or the diaphragm may perform a straight line movement, when the support is rockable.
  • the diaphragm may be mounted on the driving drum.
  • the lamp with the photoelectric cell may be mounted on the movable support of the spool or driving drum, in which case the position of the diaphragm is to be adjusted in accordance with the desired spool diameter, at which the shut-off is to be effected.
  • a shut-off mechanism for a bobbin winding machine having at least one winding unit comprising a bobbin support mounted on a pivot shaft, a bob-bin rotatably mounted on said support, a drive shaft, a first friction drum mounted on said drive shaft for rotation therewith, a second friction drum in driving engagement with said bobbin, an intermediate friction drum in driving engagement with said first and said second friction drums for transmitting rotary movement to said bobbin, a movable operating lever supporting said intermediate friction drum, a photocell unit arrangement including a diaphragm having a slot mounted on said pivot shaft for pivotal movement with said bobbin relative to said second drum, an adjustable shaft provided with means for setting the angular position of said adjustable shaft, a U-shaped support mounted on said adjustable shaft and presenting a pair of legs, one said leg carrying a photo-cell and the other a lamp disposed in radiation relation to said photo-cell, said diaphragm being disposed intermediate said photo-cell and said lamp and adapted to render said photo-cell
  • a shut-off mechanism for a bobbin winding machine in accordance with claim 2 comprising a worm gear mounted on said adjustable shaft and a worm in engagement with said gear and having a crank operative to adjust the setting of said adjustable shaft.
  • a shut-off mechanism for a bobbin winding machine in accordance with claim 1 comprising a plurality of said winding units each including a photo-cell unit having a U- shaped support and where said adjustable shaft is common to all said U-shaped supports for simultaneously adjusting the setting of said plurality of winding units.
