Definitions

  • orienting devices are used, to which the bobbins are delivered in a random oriented condition.
  • the two bars, forming part of the bobbin-ejecting mechanism, are so-positioned that during their pivotal motion, only the bar adjacent the wide end of the bobbin collides with the latter, pushing it lengthwise, until the wide end of the bobbin is over the outlet opening. Thereafter, the bobbin drops, wide end first, through said inlet opening into the discharge chute. Thus, the bobbins leave the discharge chute in a uniformly oriented manner.
  • the ejecting mechanism of the orienting apparatus includes two contour elements having working edges movable transversely to the longitudinal direction of the bobbin to be oriented.
  • the working edge which is contact with the wide end of the bobbin displaces the latter axially andcauses it to fall, wide end first, into the discharge chute.
  • the working edges which may be straight or curved, are so designed that despite a rapid transverse motion of the contour elements, they engage and displace the bobbins gently so that a highly protective handling thereof by the ejecting mechanism is ensured.
  • FIG. 1 is a sectional front elevational view of the preferred embodiment of the invention
  • FIG. 2 is a sectional view along line 11-11 of FIG. 1;
  • FIG. 3 is a fragmentary side elevational sectional view of the preferred embodiment and FIG. 4 is a perspective view of one component of the preferred embodiment.
  • the orienting apparatus shown therein includes a feed chute 200 for delivering the bobbins 201 to be oriented, an orienting number chamber 202 adjoining the outlet of chute 200 and a downwardly conically tapering discharge chute 203 for receiving the oriented bobbins.
  • the cross section of the feed chute 200 is so designed that the bobbins 201 to be oriented are superimposed therein in an axially parallel, random-oriented manner.
  • the bobbins may be introduced into the feed chute 200 through a hopper (not shown) or the like by means of gravitational forces.
  • the height of the orienting chamber 202 is slightly greater than the diameter of the wide end 207 of each bobbin.
  • the bobbins are conical configuration and used in spinning, twisting or winding machines. It is to be understood, however, that the invention is not limited to orienting conical bobbins but may find application in case of slender articles, each having ends of different sizes measured transversally with respect to the length dimension of the article.
  • each bobbin 201 in the orienting chamber 202 and the discharge of each bobbin is an oriented condition through discharge chute 203 is effected by different elements of a pusher generally indicated at 210.
  • a precompressed coil spring 213 surrounds the push rod 212 and engages, with one end, a collar 212a affixed to the push rod 212 and engages, with the other end, a spring seat 214 secured to the housing 234.
  • the spring 213 urges the pusher 210 into a withdrawn position, which it assumes in its inoperative position, as shown in FIG. 2.
  • a bar 215 fonned of a nonmagnetizable front portion 216 and'a soft magnetic rear portion 216' To the terminus of the push rod 212, remote from the pusher 210, there is affixed, in alignment with push rod 212, a bar 215 fonned of a nonmagnetizable front portion 216 and'a soft magnetic rear portion 216'.
  • the bar 215 passes through the inner space of the solenoid 219 which may be energized by electric current supplied to terminals 220.
  • the solenoid 219 When the solenoid 219 is in an energized condition, the magnetic field generated exerts a force on the bar portion 216', overcoming the force of spring 213.
  • the push rod 212 and-the pusher 210 are displaced in the direction of the arrow 221.
  • the spring 213 Upon deenergization of the solenoid 219, the spring 213 mores the pusher. 210 into its position of rest shown in FIG. 2.
  • the pusher 210 includes a lifting or separating element 222, two contour elements 223 and a locking element 224 provided with a discharge window 225. As particularly well seen in FIG. 3, these elements have a flat configuration and are arranged horizontally parallel to one another in such a manner that the path of travel of the locking element 224 extends immediately above the inlet opening 225' of the discharge chute 203 and the path of travel of the separating element 222 extends immediately under the outlet opening 226 of the feed chute 200.
  • the path of travel of the two contour elements 223 is situated at identical heights and their distance from the travelling path of the locking element 224 is smaller than the wide end 207, but larger than the narrow end 209 of the bobbins to be oriented.
  • the working edge 245 of the contour elements 223 are straight and so-arranged that they are divergent in the direction of the forward motion of the pusher 210 and symmetrical with respect to a vertical plane disposed parallel to said direction.
  • the working edges 245 are inclined with respect to one another at an angle of between 45 and 70 preferably between approximately 50 and 60
  • the travelling path of the contour elements 223 is substantially horizontal. It is, however, within the scope of the invention to move said contour elements in a path which is inclined to the horizontal (including a vertical direction).
  • a stationary horizontal web 233 which at both ends is affixed to the housing 234 of the orienting apparatus and which is disposed approximately at mid-distance between the locking element 224 and the separating element 222.
  • the purpose of web 233 is to prevent a slippage of the bobbin, resting on the locking element 224, from its position shown in FIG. 3 in the direction of the back wall 237 of the pusher 210.
  • the frontal wall 235 of the housing 234 there are provided spaced openings 236 for accommodating the leading end portions of the contour elements 223 and the locking element 224 so that, as indicted with dash-dot lines in FIG. 3, during the forward position of the pusher 210, these elements may assume a position in which their free ends protrude beyond the front wall 235 of the housing 234.
  • the locking element 224 has a planar locking face 240 and a discharge window 225 disposed between the locking face 240 and the rear wall 237 of the pusher 210.
  • the striplike parts 242 of the locking element 240 which extend adjacent either side of the discharge window 225 up to the leading edge 241 of the locking element, constitute, in accordance with the invention, support faces for the wide and narrow ends of the bobbin to be oriented.
  • the width of the discharge window 225 measured in the direction of motion of the pusher 210 is greater than the I diameter of the wide bobbin end 207, whereas the length of the discharge window 225 is less than the length of the bobbin.
  • the locking face 240 of the locking element 224 blocks the inlet opening 225' of the discharge chute 203, so that in this position of the pusher, the bobbin to be oriented may under no circumstances (even if in an incorrect position) drop into the discharge chute 203.
  • the discharge window 225 of the locking element 224 registers with the inlet opening 225' of the discharge chute 203, so that the bobbin may drop thereinto, as it will be described hereinafter.
  • the separating element 222 forming the part of the pusher 210 is constituted by a rectangular horizontal plate and has the function to lift that bobbin which rests on the lowermost bobbin to be oriented and which is partially still in the feed chute 200. Such a lifting operation is effected prior to the displacement of the lowermost bobbin of a contour element 223.
  • the working edge 245 adjacent the wide bobbin end 207 displaces the bobbin 201, so that the narrow bobbin end 209 shifts into its proper position before the discharge window 225 registers with the inlet opening 225' of the discharge chute 203.
  • the narrow bobbin end 209 was initially correctly positioned, then the working edge 245 adjacent the wide bobbin end 207 contacts the base 231 of the bobbin 201 only after a further advance of the pusher 210.
  • the bobbin to be oriented lies above the opening 225' on the locking face 240
  • the bobbin As the discharge window 225 arrives into registry with the inlet opening 225' of the discharge chute 203, the bobbin is momentarily so disposed that it is supported only at its narrow end 209, while a substantial part thereof, including its wide end 207, hangs over the window 225 which is in alignment with the opening 225' of the discharge chute 203. From this position the bobbin 201 necessarily tumbles, wide end first, into the discharge chute, as indicated in dash-dot lines in FIG. 1.
  • the pusher 210 is advanced until it abuts a stop, not shown, and thereafter, upon deenergization of the solenoid 219, returns into its position of rest under the effect of spring 213, terminating one cycle of operation.
  • This cyclical operation may be repetitively performed in a fully automatic manner.
  • the orienting apparatus described may be modified in many ways without departing from the scope to the invention.
  • the locking element 224 may be omitted without disadvantage.
  • the base portions of the orienting chamber 202 at either side of the inlet opening 225 of the discharge chute 203 may serve as supporting faces for the bobbin ends 207 and 209.
  • the locking element may be designed and arranged in such a manner that its path of travel passes between the support faces disposed laterally adjacent the inlet opening 225' of the discharge chute 203. In such a case the locking element serves only to block and open the discharge opening does not contain a discharge window.
  • contour elements instead of forming a rigid unit with the pusher, may be so designed that they may be caused to move independently from one another.
  • an apparatus for orienting bobbins, or the like having a wide and a narrow end said apparatus being of the type that includes discharge means having a longitudinal inlet opening, feed means to individually supply and position randomoriented bobbins over said inlet opening in said lengthwise alignment therewith and ejecting means to longitudinally displace each bobbin in the direction of its narrow end, causing it to tumble, wide end first, through said inlet opening into said discharge means, the improvement comprising, at least two contour elements forming part of said ejecting means, at least one of said contour elements disposed beyond and adjacent each end of said inlet opening, each said contour element movable in a path of travel towards and away from said inlet opening transversally to the length dimension of the latter, each said contour element including an integral working edge so positioned that upon displacement of the contour element towards said inlet opening, said working edge advances towards said inlet opening parallel with the length dimension of the latter, said path of travel of said contour elements being so situated that upon displacement of the contour elements solely the working edge adjacent the wide end
  • contour elements are rigidly connected and are movable as a unit.
  • contour elements are integral with a pusher movable linearly towards and away from said inlet opening transversally to the length dimension of the latter.
  • said locking element includes a discharge window movable under the random-positioned bobbin into alignment with said inlet opening.
