Definitions

  • a feeding drum for headed pins, screws, spikes or the like which is rotatable about an inclined axis and provided with parallel slots in its peripheral wall into each of which, due to the tumbling movement of the spikes within the drum, the shank of at least one spike enters during each revolution of the drum and, because of the inclined position of the drum, this spike then slides to the lowest part of the slot into an arcuate gap between the inner wall of the drum and a stationary flange along which the head of this spike slides during the further rotation of the drum until it reaches the upper end of the flange when the spike will drop by gravity out of its slot into the open upper end of a delivery pipe.
  • the present invention relates to an apparatus for automatically aligning headed pins, rivets, screws, or the like, and especially spikes for automobile tires, and for feeding them in equal positions consecutively in the same direction.
  • the feeding apparatus comprises a drum which is open at one end and rotatable about an obliquely inclined axis on a stationary support forming a wall which covers the open end of the drum and is provided with an opening through which the spikes or the like are supplied from a hopper to the inside of the drum.
  • the peripheral wall of the drum is provided with parallel longitudinal slots which extend from the open end of the drum adjacent to the stationary supporting wall for a certain distance toward the closed end of the drum and have a width slightly larger than the diameter of the shanks of the spikes or the like.
  • the stationary supporting wall is provided with a guide flange which projects into the open end of the drum and is radially spaced therefrom so as to form an arcuate gap which has a radial width substantially equal to the axial thickness of the heads of the Spikes or the like and a longitudinal width suflicient to receive the head of one spike in each slot.
  • the spikes Due to the inclination of the drum, the spikes will then slide by gravity within the lower part of the drum toward the stationary supporting wall and their heads will finally pass into the gap between the drum and the guide flange and they will then slide peripherally along the latter during the further rotation of the drum.
  • the spike in each slot within the gap is thus taken along by the drum until it reaches the upper end of the guide flange.
  • Another object of the invention is to prevent any interference in the operation of the apparatus which may be due to the engagement of a spike or the like with the upper end of the delivery pipe or with the projecting end of a previous spike which has not as yet dropped entirely into the delivery pipe.
  • the invention provides that the delivery pipe or at least its upper end is made of a resilient construction so that a spike while still at least partly in its slot hits against the upper end of the delivery pipe or against the upper end of a preceding spike which has not fully dropped into the upper end of the delivery pipe, the latter will be bent resiliently in the direction of rotation of the drum and the spike will thereafter drop out of its slot back into the lower part of the drum.
  • FIGURE 1 shows a longitudinal section of the essential parts of a feeding apparatus according to the invention.
  • FIGURE 2 shows, partly in cross section, a view which is taken in the direction of the arrow A of FIGURE 1.
  • the apparatus according to the invention which in this particular case is intended for feeding headed spikes which are to be inserted into automobile tires, comprises a perpendicular upright 1 on which a supporting wall 2 is mounted which extends within a plane which is disposed at an angle of approximately 25 to the upright 1.
  • This supporting wall 2 carries integrally thereon a bushing 3 in which a drive shaft 4 is rotatably mounted one end of which is secured to the center of the wall of drum 5.
  • the peripheral wall of drum 5 is provided with a plurality of slots of an equal length which extend parallel to each other and to the axis of shaft 1 and at equal distances from each other from the edge of the open end of the drum.
  • the side walls of the slots 6 extend in radial directions of the drum.
  • Drive shaft 4 projects through the supporting wall 2 and is provided on the other side thereof with a spring washer 7 for preventing it from shifting in its longitudinal direction relative to the supporting wall 2.
  • the outer end of shaft 4 is connected by suitable means either directly or through a reduction gear to a motor or other driving means 9 which is mounted on the supporting wall 2.
  • the supporting wall 2 is further provided with a substantially diagonal bore which extends parallel to a diametrical plane of this wall closely adjacent to one side of shaft 2, but at an angle to the flat outer surface of wall 2 which is smaller than the angle at which this surface is disposed to the perpendicular upright 1.
  • This bore contains a delivery or discharge pipe 10 which extends in the mentioned inclined direction. The lower end of this pipe projects beyond the peripheral surface of wall 2, while its upper end extends into a recess in the upper side of Wall 2.
  • This upper end of delivery pipe 10 is resilient and may consist of a coil spring 11 which extends upwardly to a point near the inner wall of drum 5.
  • the upper end of pipe 10 may, however, be made resilient in any other suitable manner or the entire delivery pipe 10 may be made, for example, of a resilient plastic or similar material.
  • the side of wall 2 carrying the motor 9 also carries a funnel-shaped hopper 12, the lower end of which projects through an aperture in wall 2 into drum 5.
  • the other side of wall 2 is provided with a guide flange 13 which projects into the slotted drum and has a width approximately equal to the diameter of the heads of the spikes 14.
  • the spikes 14 which are fitted into the hopper 12 slide from the latter into the slotted drum and collect in the lower part thereof. Due to the rotation of the drum, the spikes then carry out a tumbling movement within the lower part of the drum with the result that sooner or later one or more spikes 14 will enter each slot 6 during each revolution of drum 5. Due to the inclination of the peripheral wall of drum 5, relative to the upright 1, the first of these spikes in each slot 6 will then slide by gravity near the lower side of the drum toward the fixed wall 2 and its head will pass into the annular gap between the inner wall surface of the drum and the outer peripheral surface of guide flange 13.
  • Each of these spikes will then be taken along in its slot 6 by the further rotation of the drum, while its head will slide along the stationary guide flange 13 until it reaches the edge of the recess in the upper side of the flange and the spike 14 will then slide by gravity out of its slot 6 and drop head first into the open upper end of the delivery pipe 10, that is in the case as illustrated in the drawings, into the coil spring 11 through which it will then drop into and through the actual delivery pipe and through a flexible delivery tube or the like (not shown) which may be connected to the lower end of pipe 10.
  • An apparatus for feeding elements each having a shank and a head on one end of said shank, in a head first position in the same direction, comprising a drum, means for mounting said drum so as to be rotatable about an obliquely inclined axis, means for rotating said drum, said drum having one closed end and an open end, means for feeding said elements into said drum, said mounting means comprising a stationary cover covering said open end of said drum and having a flange thereon projecting into said open end for a distance substantially equal to the diameter of the head of one of said elements and being radially spaced from the inner surface of the peripheral wall of said drum by a gap having a width slightly larger than the maximum axial thickness of said head, said peripheral wall having a plurality of slots parallel to each other and to said inclined drum axis and equally spaced from each other and extending from said open end in the direction toward said closed end, each of said slots having a width slightly larger than the diameter of said shank and during each revolution of said drum adapted to receive the shank of
  • a feeding apparatus as defined in clause 1, wherein at least the upper end of said delivery tube adjacent to the end of said flange is resiliently flexible.
