Definitions

  • This invention 15 directed to a stacker for garment work pieces in which each work piece is fed to an arcuate receiver by con- 56] References Cited trolled air jets and is deposited in the receiver by a mechanical presser bar against the resistance of a radially disposed mova- UNITED STATES PATENTS ble table carried by a radial arm concentric with the receiver.
  • This invention relates generally to new and useful improvements in stacking devices for garment work pieces and particularly seeks to provide a novel machine for arcuately stacking a large number of work pieces, especially the type having one edgethicker than its other edges.
  • one object of this invention is to provide a high-capacity stacker for garment work pieces each having a thick edge.
  • a further object of this invention is to provide a stacker of the character stated in which the work pieces are fed individually from a sewing machine to an arcuate receiver that is associated with a radial supporting table moveable through a path concentric with the receiver.
  • a further object of this invention is to provide a stacker of the character stated in which each successive work piece is fed by air jets to a position overlyingthe top of the receiver and is then mechanically inserted into the receiver.
  • a further object of this invention is to provide a stacker of the character stated in which the operation of the air feed jets is controlled photoelectrically.
  • a further object of this invention is to provide a stacker of the character stated in which the radial supporting table is moved to successive stack support positions .as successive work pieces are introduced into the arcuate receiver.
  • a further object of this invention is to provide a stacker of the character stated that is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a top plan view of a work piece stacker constructed in accordance with this invention
  • FIG. 2 is a rear elevation thereof
  • FIG. 3 is an enlarged fragmentary section taken along line 3-3 of F 1G. 1 and shows the relative arrangements of the air jets, and
  • FIG. 4 is a left end elevation thereof.
  • the invention (as illustrated) is embodied in a stacker for a multiplicity of garment work pieces and includessewing table 5 supported by a plurality of legs 6.
  • Sewing machine 7 is operably affixed to table 5 so that the direction of work piece feed is from front to rear.
  • Folding shoe 8 is located at the front of sewing machine 7 in order to fold the edge of a work piece into a hem as it enters the sewing machine for stitching.
  • Driven feed wheel 9 is located at the rear of sewing machine 7 in alignment with the hem of the stitched work piece and serves to advance the work piece toward 7 the feed elements of a stacker assembly (generally indicated A) mounted to the rear of sewing table 5.
  • Stacker assembly A includes a pair of spaced rearwardly extending support arms 10,10 having their forward ends secured to the rear edge portion of the sewing table 5.
  • the rear end of each arm 10 is provided with an upstanding post 11 which together support horizontal bar 12 in a plane above that of the top of the sewing table and in spaced parallel relation to the rear edge thereof.
  • a first tubular air feed element 13 is secured beneath bar 12 in general alignment with the hemmed edge portion of the work piece and slightly above the plane of the top of sewing table 5.
  • the front end of feed element 13 overlies a substantial portion of the rear section of the sewing table and the rear end of the feed element 13 extends rearwardly beyond the rear edge of the sewing table a distance substantially equal to the length of the work piece.
  • Feed element 13 is provided with a pair of laterally extending spaced parallel rods 14,14 that adjustably support a second tubular air feed element 15 identical with feed element l3."
  • the bottoms of the feed elements are provided along their full lengths with a multiplicity of spaced downwardly and rearwardly extending apertures 16 (see FIG. 3) that serve as air jets to move or feed the work piece rearwardly when air under pressure is introduced into the interior of the feed elements.
  • each of the feed elements 13 and 15 is closed by a depending abutment plate 17, each of which cantileverly supports a tubular bottom rail 18 that extends forwardly into proximity with the rear edge of sewing table 5 and in a plane at or slightly below that of the top of the sewing table.
  • the tops of rails 18 may be provided with upwardly and rearwardly directed apertures 19 to assist in feeding of the work piece when air under pressure is introduced into the interior of the rails.
  • a solenoid controlled air valve 20, mounted on top of bar 12 supplies air through hoses 21 to the feed elements 13 and 15 on a cyclic basis as will be hereinafter described more fully.
  • the same valve 20 controls the supply of air to rails 18 whenever they are perforated to assist in the feeding function of feed elements 13 and 15.
  • a head bar 22, affixed beneath bar 12 carries photoelectric cell 23 which is located adjacent the rear edge of sewing table 5 for sensing the passage of a work piece being advanced by feed elements 13 and '15 (and possibly rails 18).
  • the beam from cell 23 is normally uninterrupted.
  • air valve 20 when a work piece is advanced by the feed dogs of the sewing machine 7 and feed wheel'9 to the point at which the rear (leading) edge of the work piece interrupts the cell beam, it actuates air valve 20 to admit air to feed elements 13 and 15 to continue the advance of the work piece to a position overlying the upper end of an arcuate receiver generally indicated 24.
  • Receiver 24 simply is a metal plate 25 bent into a uniform quadrant of a circle with its upper end secured to head bar 22 and its lower end secured to bottom bar 26 affixed to the frame of the sewing table.
  • Piston 28 of cylinder 27 carries at its lower end a press bar 29 having a laterally extending U-shaped removable press frame 30, which together force the work piece downwardly through and beneath rails 18 into receiver 24.
  • Plates 17 not only serve to close the ends of tubular elements 13, 15 and 18 but also serve as abutments to limit the rearward feed of the work pieces and thus assure their proper registry with the top of receiver 24.
  • receiver 24 When receiver 24 becomes completely filled, the entire unit is stopped until the receiver is emptied and is then restarted.
  • a stacker for garment work pieces including a receiver, means for supporting a garment work piece at the entrance to said receiver, means for feeding a work piece onto said supporting means, and means for positively displacing said work piece from said supporting means into said receiver, and said receiver including an arcuate plate of uniform curvature disposed with its axis parallel to the direction of feed of said work piece and in which said work piece displacing means operates in a direction that is substantially parallel to a tangent at the entrance to said receiver, said receiver additionally including a radially oriented table for supporting a stack of successively deposited work pieces and incrementally moveable through an arc concentric with said arcuate receiver plate.
  • said work piece feeding means includes at least one air jet feed element overlying the plane of travel of said work piece in proximity thereto and extending from a position ahead of said receiver to a position overlying the entrance to said receiver.
  • the stacker of claim 2 additionally including means for initiating operation of said work piece feeding means as the leading edge of said work piece is directed toward said receiver and for discontinuing operation of said work piece feeding means as said work piece registers with the entrance to said receiver.
  • said work piece feeding means comprises a pair of spaced parallel air jet feed elements overlying the plane of travel of said work piece in proximity thereto and extending from a position ahead of said receiver to a position overlying the entrance to said receiver
  • said work piece supporting means comprises a pair of spaced parallel rails underlying said air jet feed elements and spaced therefrom a distance sufficient to permit passage of a work piece therebetween, said displacing means being effective to move said work piece downwardly between said rails 5.
  • said spaced parallel rails are also air jet feed elements.
  • the stacker of claim 4 additionally including means for varying the spacing between said air jet feed elements and the spacing between said rails.
