  • the blank 2 upon being lifted by the lifting bar 3, the blank 2 attaches to an adhesive tape 7 which is pressed to an adhering contact with the fabric blank when the lifting bar with the pocket blank on top of it moves against the same adhesive tape.
  • the adhesive tape transfer device is actuated when the pulley 12 removes the blank being held over the roller conveyors 57a Photocell 8, when it senses no blank in the path of an actuating lamp 9, advances the conveyor belts 4 to keep a supply of blanks on the lifting bar 3.
  • this blank After the adhesive pickup of the blank by the pickup device, this blank is swung 90 clockwise with the blank securely dangling from the adhesive tape and transferred over to an input conveyor 57a. Thus, this blank is held over continuously rotating and sprocketand chain-interlinked conveyor rollers 10 forming the input conveyor 570.
  • a puller wheel 12 When the sewing machine 11 is about ready to receive the next blank, a puller wheel 12 is actuated, and when the puller wheel 12 slightly engages the fabric blank 2, a conveyor roller 10a detaches the blank from the adhesive tape 7 and feeds it along an input path on conveyor 57a.
  • a guide rail 13 on the surface of the input conveyor 57a which rail is at a diverging angle to an imaginary line perpendicular to axis of rotation when viewed towards the sewing machine 11, guides the fabric towards the sewing machine as the conveyor rollers 10 urge the blank snuggly against the rail.
  • the length of the conveyor and the rotating velocity of the rol lers can be appropriately adjusted if needed.
  • a side guide 14, oriented vertically on a highly polished sewing table 15, is placed again at a slight angle from that defined by a normal feed direction of the sewing machine, which, in this instance sews straight.
  • the side guide 14 urges the fabric blank 2 being sewn away from the straight line and away from the sewing machine head 111. This gentle urging aids in keeping the stitch pattern at a uniform distance from the edge ofthe blank.
  • an additional guide means is required because, in practice, the guiding action favors holding the pocket against the output side of the side guide 14 more than against the input side of the side guide 14, and as a consequence of the sewing machine feed dogs 112 being located adjacent to the output side of the guide. It was found that if a drag were introduced on the limpid fabric blank 2 on the input side of the side guide, the proper feeding was achieved. A drag of the necessary kind is obtained by a drag roller 115, such as illustrated in FIG. 1, Other equivalent means but which are less preferred are rollers, belts, or other friction devices.
  • a further guide means is needed, it is conveniently in the form of an idler roller 16. Its axis of rotation is askew to the perpendicular axis of rotation of the next to last conveyor roller 10b on the input conveyor 570.
  • a brief explanation is as follows: as the sewing machine presser foot 113 comes down on the incoming and unsewed blank 2, this idler wheel 16 makes a low pressure contact on the trailing edge of the incoming blank 2 by pressing it against the conveyor roller 100. This action causes a sidewise urging of the blank and acts as a necessary guiding hand" during the first few critical stitches. After these stitches, the idler wheel 16 is retracted and the subsequent sewing of the blank is accomplished without the aid of this idler wheel 16.
  • the actual sewing is carried out by lowering the presser foot 113 on the incoming blank and effecting the continuous guiding of the pocket blank 2 by the side guide 14 and drag roller 115.
  • the photocell 19 sensing the end of the blank slows down rapidly the sewing machine for the last few stitches on that side so that the machine can be prepared for controlled stopping in a needle-down" position when photocell 20 senses the end of a blank.
  • the presser foot 113 is raised.
  • a demand for a new blank is signalled by a photocell 19 when it senses no interruption by a sewn blank after having accounted for the previous two stitching passes.
  • This slowing down is needed because the machine cannot be stopped accurately in the needle-down position while it is running at its conventional stitching speed.
  • This slowed down speed of sewing is called inching speed hereafter.
  • the photocell 20 detects the end of the blank (bottom of pocket) and stops the machine.
  • the needle 21 is now at an equal distance from the edge of the pocket blank at the side and bottom of this blank. At this time, the sewing machine presser foot 113 and the drag wheel 115 lifts. The blank 2 is now free from all means engaging the same save for the needle 21 which is piercing its corner.
  • a pocket turner rod 22 having an umbrella lip extension 222 on a sliding block 221 is actuated causing the pocket blank 2 to rotate pivoting the blank on the needle 21 in its down position.
  • the side guide means against which the pocket blank is urged has a semicircular segment space 142. Upon turning the blank 2, this segment space 142 allows the necessary clearance for a pocket blanks corner.
  • a pocket corner lifter cylinder 23 is projected vertically, for example by suitable means, such as a pneumatically activated rod or cylinder 231, just before the new pocket would have made contact.
  • the thread chain 58 In order to separate these blanks, the thread chain 58 must be broken. it is accomplished by having a conveyor roller 10c geared to run several times faster than the other rollers and activating a double wheeled forcing roller 24 and to press against the rapidly rotating roller when the proper distance is observed by a photocell 56. This action accelerates the pocket and breaks the thread chain. As the finished blank interrupts the light beam of photocell 25 at the end of the conveyor, it activates a stacking arrangement consisting of a stacking gridiron 26 which fits between the roller conveyors 10. A pinion 27 is activated such as by pneumatic means illustrated by a cylinder 28 pushing a suitable rack 29. A motor 30 which may be of the same make as 39 (described hereinafter) with a pinion 31a and rack 31b drops the receiving table 32 on each transfer of a new blank for a distance equivalent to the thickness ofa blank.
  • the belt conveyor l which advances the fanned out pocket blanks, has three V'formed belts d, as the conveying means. These belts are trained around pulleys on shafts do and db either of which can be driven by a motor. A suitable motor is the same as 39 used in the base ofthe pickup and transfer device 5.
  • the two legs are pointing away from conveyor F570 and which has upturned edges de at both sides. These edges de are tapering to become level at the table portion of the guide table dd, i.e. at the end abutting or proximate the input conveyor 57a.
  • the table end dd of the table-guide if made of the same piece of metal is polished and curved slightly downwardly towards the rollers ill to minimize the dragging friction of the pocket blank 2 when it is pulled over the guide table dd and onto the rollers llll.
  • the table portion of the guide is made ofa separate piece it curves downwardly towards the guide-table dd as well as towards the rollers lll overlapping slightly the last.
  • the end portion of guide table dd is made sufficiently narrow to accommodate the lifting bar El. Further, the shaft db is placed slightly below the guide table element dd to disengage the front part of the pocket blank 2, before the blank is urged further onto the guidetable dd and over the lifting bar 3, by the conveyor belts d.
  • the guide-table dd may have the downwardly curving portion of it which is overlapping the input conveyor 57a made as a separate piece.
  • the box lllll placed longitudinally next to the belt conveyor ll contains the electrical circuit elements for the conveyor l, the pickup and transfer device 5, and additional pneumatic conduits and valves used with these devices as further described herein.
  • the other electrical circuit elements as well as the pneumatic devices are enclosed in the box identified in Fl G. l as ill/'1 and placed alongside the output conveyor 57b.
  • the adhesive tape pickup and transfer device 5 will now be discussed as it is used for placing the pocket blank 2 on the input conveyor 57a with the aid of the lifting bar El.
  • the pickup of the pocket blank and transfer ofit is effected bythe transfer device 5 (hence, a pickup and transfer device) consisting of an upper tape reel 33 which is free to rotate around an axis Zld of the transfer device 5.
  • a lower wheel 35 rotates around axis 3d.
  • the adhesive tape '7 is unwound in small increments or continuously at very low rate from the upper tape reel Illl by winding it on lower tape reel 35 which is driven by means of a motor 38 through a very slowly turning gear train El? driving the reel with belt 36.
  • the pickup and transfer arm 6 of the transfer device fl rotates through in a clockwise and counterclockwise direction by means of a motor fill in the base of this device.
  • This motor is appropriately actuated by a signal from the puller wheel 12 when the puller wheel l2 removes the previous blank. This blank is heldby the pickup and transfer arm 6.
  • the adhesive tape 7 is sufficiently sticky to hold the blank over the conveyor 57a while the rollers rotate at full speed.
  • the motor 39 Upon actuating the motor 39, it swings, counterclockwise, the pickup and transfer arm 6 to a predetermined position over the lifting bar ll over which the motor 39 is automatically stopped.
  • the appropriate stop position is determined by a counterclockwise limiting switch d ll riding on a raised counterclockwise limiting cam dl fixedly and nonrotatingly attached to a shaft d5 holding the pickup and transfer device 5.
  • the switch d ll is deactivated by a depression in the cam at the end of the swing.
  • This bar is covered with an elastomer, such as sponge rubber ddZ, and it lifts upwardly the several layers of the fanned out pocket blanks by means of one or two lifting bar cylinders such as the illustrated single cylinder dd guided by rods ddll,
  • the cylinder upon retraction, activates the motor 39, and it returns the arm 6 over the conveyor rollers llll with the motion being stopped by a clockwise limit switch d2 activated by a clockwise cam d3 and affixed nonrotatingly to a sleave and in turn tothe shaft, the same as cam dl.
  • These two switches 40 and 4-2 are affixed to a housing d'll which rotates around the shaft and is driven by motor 39. These switches make contact when riding on a raised cam. Of course, these same switches may also make contact when riding on a cam depression.
  • the motor 39 which drives the pickup and transfer as sembly is attached to a shaft 45 at the base of a pedestal 46 housing the shaft d5.
  • the respective positions of the device 5 are illustrated in FIG. 2 by the dashed lines.
  • This motor is reversible, and in cooperation with switches 40 and 42 turns 90 in either direction.
  • the motor 39 has substantially no coasting characteristics, i.e., it can be stopped in a predeter' mined position with an error of about :1 .5 angular degrees.
  • a representative motor is SSSllPlRC available from Superior Electric Company, New England, Connecticut.
  • the adhesive tape 7 is carefully guided onto the free riding guide pulleys d7 disposed vertically to the line of travel of the tape and then, by imparting a 90 twist, the tape is guided over a rimless but crowned guide pulley dd which has its rotating shaft affixed to the pickup transfer arm 6 about perpendicular to the axis of rotation of the conveyor pulleys and with the lower edge of the pulley dfl protruding below the arm 6.
  • the positioning of the respective tape holding and guiding elements is on a line through the middle of the perpendicularly transverse axis of pulley 48, the middle of longitudinal axes of pulleys d7, and the middle of the axes on which the tape reels 33 and 36 are rotating, thus giving the best operating characteristics for keeping the tape operating smoothly and without overriding.
  • the tape 7 is advanced only during the counterclockwise swing of arm 6 by an appropriate increment.
  • FIG. 3 shows an end view of the pocket blank conveyor 57a with a conveyor roller 10 and the adhesive tape 7 holding a pocket blank 2 which is removed from the tape 7 when the puller wheel l2 is actuated by the pneumatically driven cylinder 50, spring loaded to reside in the up position. Once detached, the blank travels towards the sewing machine on the input conveyor 57a.
  • equivalent lifting means in place of the pneumatic cylinders 44 may be employed, such as cams, racks and pinions, wheels connected through a pitman lifting the bar, etc.
  • the tape drive mechanism may be provided with a ratchet mechanism and keyed to the 90 oscillating motion of the drive shaft 45 as provided by gears coupled to the motor 39.
  • FIG. 5 depicts a top view of this subeombination of elements.
  • the sewing machine II which is employed is of the conventional type, such as Singer 28! or a similar machine in which sewing walks the fabric through the machine to generate a stitch pattern by the use of feed dogs.
  • various modifications are employed in the operation of this machine in respect to the fabric guide means.
  • GUIDE MEANS ASSOCIATES WITH CONVEYOR 57a Thus, after the pocket blank 2. has been detached from the adhesive tape, this blank 2 is guided by the conveyor rollers (which are drivlngly connected by chain belts, or gears to each other and to a motor not shown and generally run continw ously). As the blank moves towards the input side of the sowlng machine ll, it is urged against a guide rail l3. As previously explained, the guide rail i3 is at an angle of about 2 to 3 but preferably 2.5 angular degrees to a line perpendicular to the rotating axis ofthe rollers 10. Of course, the angle may be varied.
  • the line perpendicular to the rotating axis of c the conveyor rollers 10 is directed at a slight angle, i.o. on the same order towards the feed dog, he. at an angle opposite from that of the side guide id and about the same order of magnitude as for rail 13.
  • a pneumatic cylinder (not shown) may be provided on the input side ofthe conveyor 57a attached to the guide rail id for vibrating slightly the conveying mechanism in the event the llmpid fabric is stuck or is not advanced satisfactorily.
  • an input angle of the input side conveyor 57:! may be selected which is generally suitable.
  • the rate at which the conveyor rollers id are rotated as well as the length of the conveyor, is. the total number of rollers, may be selected to provide for the best operating conditions.
  • the function of the hood 52 is to prevent the upturning of corners of a new blank being received on the sewing table 15 or when turning on this table 15 the blank 2 through a 90 angle at the two corners of the blank.
  • the geometry of the particular blanks may be such as to overlap at the trailing corner away from the needle 2i before sewing can begin on the new blank.
  • a pocket corner lifter 23 is provided which is activated by sensing of the incoming blank by the photocell 19.
  • This lifter rod 23 is activated by a pneumatic means such as cylinder 231 through a solenoid valve appropriately interconnected to the control circuit as further explained herein.
  • the lifter rod 23 is retracted immediately when a properly programmed signal is received, i.e. when the new blank is trapped for sewing by the sewing machine presser foot 113.
  • the means effecting a trapping of an incoming blank cooperate as follows: After the new blank goes under the hood 52, the roller drag 115, which is canted at about -l0 angular degrees towards the line defined by the sewing machine when stitching, engagesthe blank.
  • the roller drag wheel ll5'and its assembly is illustrated in FIG. 5 and in cross section thereof in FIG. 5a in more detail.
  • the support axis a upon which the roller rotates and is pivoted for disengagement from a blank is shown as it rests on a support I151; beyond the side guide 14 on the sewing machine ll table.
  • a fulcrum arm 1150 projecting below the support axis 115a of the roller drag wheel provides a surface upon which a rod from a pneumatic cylinder 115d extends to overcome the spring 115a which normally holds the drag wheel 115 down.
  • the spring 115m is adjusted, by appropriate means such as a screw and/or eyebolt attached to the upper arm 1115f of the housing, for proper tensioning and, thus a variable drag effect by wheel 115.
  • the roller drag wheel H5 is activated by the means further explained in the description pertaining to the electrical circuits. For the understanding of the mechanical operation, it suffices to mention that the roller drag 115 is lifted when the presser foot 113 is lifted for pivoting the blank about the sewing machine needle 2i.
  • This roller drag Hi5 can be a knurled roller, wheel, or a friction type device, and adjusting its drag angle with respect to the direction of pocket travel will optimize the guiding characteristics.
  • the drag roller 115 is found to be especially useful as the output side 1st of the side guide is is adjacent to the sewing machine feed dogs I12, and the added drag induces the pocket to fit snugly against the side guide 14 preventing the feed dogs to move the pocket away from the guide.
  • this drag coacts with the action exerted by the feed dogs 112, urging the blank against the side guide M which is at a slight angle away from the parallel line to which the feed dog would urge the blank if the same were not restricted by the side guide to (which is conveniently in the form of a polished metal surface).
