Definitions

  • This disclosure relates to a registration device for successively placing pieces of fabric in a predetermined position against retractible stops by means of pulsating jets of air blown in the direction of the stops so as to register the piece.
  • registration devices have used fixed stops which interfere with the removal of the registered piece or have motive means positioned above the support surface along which the piece is translated or otherwise have required a manual step in the registration procedure.
  • FIG. I is a top plan view of the novel registration device
  • FIG. 2 is a sectional view taken along line 2-2 of FIG. 1;
  • FIG. 4 is a sectional view taken along line 44 of FIG. 3;
  • FIGS. 5 through are a schematic representation of the operation of the registration device wherein: FIG. 5 shows the piece being brought to the support surface; FIG. 6 shows the misaligned piece disposed upon the support surface; FIG. 7 shows the stop means in raised position and the nozzle operative to translate the piece in the direction of the stop means; FIG. 8 shows the piece in registered position with the stop means raised and the air nozzles still operative; FIG. 9 shows the piece in registered position with the nozzles inactive and the stop means retracted; and FIG. 10 shows the piece being removed from the support surface.
  • the novel registration device designated generally as 20, is shown in FIGS. 1 and 2.
  • the device is mounted on a frame 22 to which a supporting surface 24 of low friction characteristics is connected.
  • the support surface 24 has a front edge 26 adjacent to which is a slotted section 28 having slots 29 extending perpendicular to the front edge in a generally designated X direction.
  • slotted section 30 is formed adjacent the side edge 32 and has slots 31 thereof formed substantially parallel to the front edge 26 in a generally designated Y direction.
  • the slotted section 30 is upstream of the slotted section 28, with the front edge 26 considered to be downstream thereof.
  • the slots may be formed as cutouts in the support surface 24 or by placing a plurality of parallel rods 34 in equidistantly spaced recesses 36 of the frame 22.
  • Operation of the air cylinder 56 will cause thecarriage 42 to be raised to the position shown in FIGS. 1 and 2 or retracted to the position shown in FIGS. 3 and 4.
  • An air cylinder 56 is mounted to each of the arms 44 and as shown in FIG. 4 will receive pressure air from a suitable source (not shown) through a line 62 having branches 64 and 66.
  • the arm 44 has a projection 68 at the front end thereof which is raised position of carriage 42 engages a frame abutment 70 to set the carriage 42 in the horizontal plane so that the stop pins 50 extend in a vertical plane.
  • a pair of limit switches 72 and 74 are connected to the frame adjacent the path of travel of one of the projections 68 whereby in the retracted position the actuating finger 76 of limit switch 74 is engaged by projection 68, while in the raised position, the projection 68 engages the actuating finger 78 of limit switch 72.
  • the limit switches 72 and 74 are part of the electrical control circuit (not shown) which is utilized to control the operation of the pneumatic circuit (not shown) so as to actuate the registration device 20 in a manner to be described hereinafter.
  • Air lines 88 are connected to each of the nozzle assemblies 82 to deliver air thereto in a pulsated alternate fashion from a suitable source (not shown) corresponding to the direction in which the nozzle outlet indicated generally as 90 and 90,, is facing, with x indicating a nozzle outlet facing in the X direction and Y indicating a nozzle substantially in the Y direction which the present instance has a small component of X direction so as to facilitate obtaining the registration position.
  • the nozzle and nozzle assemblies 82 may be of the general type shown and described in US. Pat. No. 3,268,222, granted Aug. 3, I966.
  • FIG. 5 shows a fabric piece 100 being conveyed by a vacuum head 102.
  • the registration device is in an inactive condition in that no air is being supplied to the nozzle assemblies 82 and the stop assemblies 38 are in the retracted position.
  • the stop pins of the stop assemblies 38 will be raised to vertically extend through the slots 29 and 31 of the slotted sections 28 and 30 respectively. Since the shape of the fabric piece 100 to be registered is known it is a simple matter to adjust the stop pins 50 in a pattern corresponding to the edges which will contact the same. Accordingly, the stop pins adjacent the front edge 26 are placed in a curve matching that of the leading edge 104, while the stop pins 50 adjacent the side edge 32 are located in a straight line substantially perpendicular to the leading edge 26 corresponding to the straight side edge of the fabric piece 100 which will be aligned thereagainst.
  • the pulsated blast of air are timed so as to last long enough to insure that proper registration position of the fabric piece 100 has been obtained before it is automatically shutoff.
  • FIG. 8 the fabric piece 100 is shown in registration position with the stop assemblies 38 in the raised position and the nozzle assemblies 82 still operative. The period that the nozzle assemblies 82 are operative is sufficiently long to avoid premature shutoff which would result in a not obtaining registration position. In any event, once registration has been obtained and ling of the fabric piece 100. Prior to retracting the stop assemblies 38, the air blasts from the nozzle assemblies 82 ceases, with the fabric piece in registered position as illustrated in FIG. 9. A suitable removable means, such as a vacuum head 106 will engage the registered fabric piece 100.
  • FIG. 10 shows the fabric piece 100 being removed from the support surface 24 after completion of the registration thereof and sets the stage for repeating the cycle.
  • a registration device successively to place pieces of fabric in a predetermined position comprising:
  • the stop means including a pair of stop carriers pivotally mounted beneath each of the rows of slot means,
  • the stop pins define a predetermined pattern for the pieces to contact upon coming to the registration position
  • nozzle means mounted in the support surface to form two rows of nozzle means, one row of nozzle means disposed inwardly of one of the rows of slot means and the other row of nozzle means disposed inwardly of the other of the rows of slot means, and
  • each row of nozzle means separately connected to a source of pressure air, alternately operative, successively to translate the piece in the direction of one of the rows of slot means and then in direction of the other of the rows of slot means, whereby said piece is brought into the registration position.
