Definitions

  • This invention relates generally to sawing. machines. More particularly, but not by way of limitation, this invention relates to an attachment for sewing machines that are used for sewing tags, labels, pockets, etc. onto a piece of material.
  • tags, labels, pockets and similar items that are to be sewn onto another piece of material will be referred to hereinafter as "overlays.”
  • Overlays are sometimes manually placed in the machine or attachment wherein they are sewn on a piece of material.
  • Such machines constructed in the past, have included so much apparatus adjacent to the sewing area that it is difficult, at best, for the operator to see the overlay and where the overlay is to be placed on the material or workpiece.
  • An object of this invention is to provide an attachment for sewing machines wherein the overlay is placed therein in a position clearly observable by the operator and in which the apparatus moves the overlay into position adjacent to the work piece for sewing the overlay thereon.
  • This invention then provides an improved sewing machine attachment for sewing overlays to a workpiece
  • the sewing machine includes a base, an arm, a reciprocating needle carried by the arm and a presser foot on the arm adjacent to the needle and arranged to engage and hold the workpiece against the base.
  • the attachment comprises holding means for retaining the overlay; and pivot means located on the arm and carrying the holding means for pivoting a portion of the holding means from a first position adjacent to the arm for placing an overlay in the holding means to a second position wherein the overlay is disposed between the presser foot and the base and adjacent to the workpiece.
  • the sewing machine 20 includes a head 24 having an arm 26 projecting outwardly over a base 28.
  • the arm 26 carries a presser foot 30 that extends downwardly therefrom for holding materials against the base 28.
  • the sewing machine 20 also includes a needle and thread (not shown) that are located in the vicinity of the presser foot 30 that is used to sew pieces of material together.
  • a support 32 Projecting outwardly from the end of the arm 26 and affixed thereto is a support 32 which carrier a platen 34 at its outermost end.
  • the platen 34 serves as a base or table upon which the overlays, in this case a label 36, can be placed by the operator.
  • the attachment 22 also includes a pair of gripping members 38 and 40 that are located on opposite sides of the platen 34.
  • the grippers 38 and 40 may be mirror images of each other. However, if the overlay is of some special configuration, the grippers 38 and 40 may be suitably configured to hold such overlay.
  • the gripping members 38 and 40 are mounted on a support bar 42 and are adjustable thereon and relating to each other by a pair of set screws 44.
  • the construction of the gripping member 38 is shown more clearly in FIGURES 2 and 3.
  • Gripping member 38 also includes a gripper body 46 having a recess 48 formed therein that pivotally receives a cloth engaging member 50.
  • a pneumatic. cylinder 52 located on the body 46 is arranged to engage the cloth engaging member 50 to cause it to pivot in the cavity 48.
  • a stop plate 54 is mounted on the side of the body 46 so the material to be gripped by the gripping member 38 is trapped between the cloth engaging member 50 and the stop plate 54.
  • the support bar 42 is securely fastened to a pivot arm 56 that has its opposite end attached to a motor 58 for pivoting the arm and attached gripping members 38 and 40 through the positions illustrated in FIGURES 4 and 5.
  • the arm 56 is composed of two parts 60 and 62 (see FIG. 6) which are, as shown in FIG. 10, movable together and apart by a pneumatic cylinder 64 that is carried by the arm 56.
  • the cylinder 66 Upon reaching a predetermined location during the arcuate motion, the cylinder 66 is actuated to move the parts 60 and 62 relatively together. Further pivotal motion of the arm 56 follows until the label 36 is located above the base 28. Upon reaching the base 28, the cylinder 66 is aain actuated to move the label 36 and gripping member 40 toward the base 28 as illustrated in FIGURE 4.
  • the cylinders in the gripping members 38 and 40 are actuated to release the label 36.
  • cylinder 66 is again actuated to raise the gripping member, and the arm 56 is pivoted upwardly returning the gripping members 38 and 40 to the position illustrated in FIGURE 1. Since the label 36 it retained on the base 28, it is not necessary to extend the arm 56 during the return motion. The extension it only necessary so that the label 36 will clear the platen 34 and the material on the base 28.
  • the attachment 122 includes a bifurcated support member 124 having an upper tine 126 and a lower tine 128.
  • the support member 124 is fastened to the arm 26 of sewing machine 22 by threaded fasteners 130 or other suitable means. It will be noted that the attachment 122 is positioned so that it will operate in conjunction with the pivot arm 56 previously described in connection with the embodiment of FIGURE 1.

  • FIGURE 6 illustrates the attachment 122 in a position ready to receive the overlay. As illustrated therein, the holding member 156 is elevated above the platen 160 permitting the operator to place the overlay 162 on the platen 160 in the position illustrated in FIGURE 7.
  • the cylinder 132 is actuated moving the holding member 156 down and into engagement with the overlay 162 as illustrated in FIGURE 9. During this stage of the operation, the arm 56 does not move.
  • FIGURE 11 illustrates schematically, the way that the attachment 122 accomplishes the folding of the edges of the overlay 162.
  • the attachment 122 is in the position illustrated in FIGURE 9, that is, in the position with the holding member 156 securely pressing the overlay 162 into engagement with the platen 160.
  • the dashed-line outline of the overlay 162 in FIGURE 7 indicates that the overlay 162 does extend outwardly over the gripping members.
  • the cylinder 142 is actuated by the controller 194 to cause the folding blade 178 to move along the surface of the overlay 162 toward the gripping member 166 and, due to the size of the overlay 162 , the edge thereof bends back over the folding blade 178.
  • the cylinder 172 and the gripping member 166 are actuated to cause the cloth engaging members to move in a direction to clamp the cloth in the gripping member 166. This movement also holds the folded edge intact.
  • the cylinder 142 is actuated so that the folding blade 178 retracts and is not clamped by the gripping member 166.
  • the overlay 162 is a pocket to first activate the cylinder 148 folding the edge of the overlay 162 adjacent to the folding blade 180. Then, the cylinder 150 is activated to fold the edge of the overlay 162 adjacent to the folding blade 182 and gripping member 170. After the two angled edges have been folded and gripped by the gripping members 168 and 170, the cylinder 142 ia actuated to fold the edges adjacent to the gripping members 164 and 166 and to actuate the gripping members to retain those edges in the folded condition.
  • the cylinder 132 is actuated to move the holding member 156 away from the platen 160, that is, to the position illustrated in FIGURE 10.
  • the cylinder 64 is actuated to separate the portion 60 and 62 of the arm 56 and lift the gripping members and the overlay 162 away from the platen 160 thereby providing the necessary clearance between the overlay 162 and platen 160 so that the arm 56 can be pivoted downwardly.
  • the arm 56 carries the gripping members and the overlay 162 into a position adjacent to the base 28 so that the presser foot 30 can engage and retain the overlay 162 on the base 28 and in position for sewing the overlay 162 onto the workpiece.
  • the arm 56 is then pivoted upwardly returning the arm 56 and the gripping members mounted thereon into the position illustrated in FIGURE 6 and ready to receive the next overlay.
  • the modified form of gripper illustrated in FIGURES 12, 13 and 14 can be used in lieu of the grippers 38, 40, 164, 166, 168 or 170.
  • the gripping member is generally designated by the reference character - 200.
  • the gripping member 200 includes an elongated body 202 upon which there is pivotally mounted a cloth engaging member 204. It will be noted that the body 202 is provided with a notch or shoulder 206 that extends along the length thereof and is arranged to be disposed under the cloth engaging member 204. The notch 206 is sized to receive the particular overlay with which the gripping member 200 is to be used.
  • the gripping member 200 is provided with a pair of spaced bores 208 that are connected with the source of pressurized air by conduit 210.
  • Each of the bores 208 is provided with a reciprocating piston 212 that is movable in the bore 208 in response to pressure in the conduit 210 to engage and raise the cloth engaging member 204 to permit placing the overlay in the notch 206 or to release the overlay therefrom.
