Definitions

  • the present invention relates to a pouch forming and filling apparatus and method and more particularly to a method and apparatus for forming and filling a plurality of adjacent pouches in a long web with items so that the items are both individually protected and readily accessible.
  • the value of individually protecting similar subassembly parts takes into account substantial reduction of damage by abrasion, damage by deformation, damage by dirt or dust collecting thereon, and/ or damage by having several adhesive coated parts prematurely adhering to each other with a result of loss of both time and parts when attempts are made to separate them.
  • an object of the present invention is to provide a new and useful pouch forming and filling apparatus and method for separately storing and protecting individual subassernbly items for later presentation at an assembly station.
  • a folded vinyl or polyethylene web or strip is passed downwardly through the pouch making and filling apparatus of my invention with its longitudinal location being controlled precisely by a selectively operable driving roller.
  • a spreader inserter arm Near the longitudinal center of the folded plastic strip within the forming and filling apparatus is a spreader inserter arm for opening the folded strip sufficiently to allow insertion therein of a finished subassembly item.
  • the finished item is supplied from a finishing machine such as a punch press, a finish painting mechanism, or the like by a chute means which drops the part into a portion of the inserter where it may be sensed and driven by an air blast fully into the opened strip.
  • the roller drive system is energized to move the strip downstream a predetermined distance where it stops and a lateral seal is developed upstream of the item by a heating means.
  • the strip is prepared to receive a next item.
  • the now pouched strip it is wound on a reel which provides large flanges to prevent the loss of items through the open end of the pouches formed by the series of lateral seals.
  • FIG. 2 is a detailed side view of a portion of the arrangement shown in -FIG 1;
  • FIG. 3 is a cross section view taken along the line 3-3 of FIG. 2.
  • FIG. 1 I have shown a folded polyethylene web supply reel It) with a folded web or strip 12 being pulled therefrom by a drive roller 14 under the control of a motor 15.
  • a backup roller 16 is forced thereagainst by spring means (not illustrated).
  • the strip 12 is passed over a guide roller 17 and what is often referred to as a dancer roller illustrated as a guide roller 18 journaled on a relatively stiff spring means 20.
  • a dancer roller illustrated as a guide roller 18 journaled on a relatively stiff spring means 20.
  • the springs 20 is flexed and thereby provides continued tension to unwarp the strip 12 from the supply reel 10.
  • a somewhat similar spring means 22 is used to bias a pad 23 against the supply reel 10 and prevent its unwinding in the absence of substantial tension in the spring 20.
  • a first clutch means 25 is a magnetic clutch which may be operated to transmit torque only when energized, and a second clutch means is a magnetic brake 26 which will prevent rotation of the drive roller 14 when energized.
  • clutch means are energized, as are several other mechanisms of the present invention, in accordance with the operation of a timer 30.
  • the timer 30 be electronic circuit equipment, precisely timed and easily regulated.
  • other timers as are known in machine equipment controls may be made to operate effectively with my invention.
  • the signals passed over the wires 31 and 32. to the clutches 25 and 26 are mutually exclusive in the sense that only one signal is developed at a time, whereby when the clutch 25 is energized to drive the roller 14, the brake 26 is de-energized so that the roller 14 may be driven and when the brake 26 is energized, the clutch 25 is de-energized.
  • a spreader inserter 34 which has a portion 35 thereof extend a substantial distance inwardly between the two sides of the folded strip 12 so that spreading of the strip is assured.
  • a supply chute 37 coupled to a part finisher 38 shown in the block form.
  • the part finisher 38 may be a punch press, a relief etching device, or the like.
  • My invention is arranged to operate at velocities greater than those at which items 39 are finished.
  • One sensing means specifically illustrated is a photodetector arrangement 40 which, when the item 39 is in front thereof, develops a signal to energize a valve 42 to supply air to a nozzle 44 which results in an air jet to blow the item 39 through the inserter into the region of the arm 35.
  • Another sensing means again illustrated in the form of a photodetector 46, senses the arrival of the item 39 within the folded strip 12 near the end of the arm 35.
  • the item 39 in the region of the photodetector 46 blocks light flux from a lamp 47 whereupon the air valve 42 is de-energized.
  • the air valve 42 is operated by means of a magnetic or electric drive mechanism 48.
  • a signal from the photodetector 46 is applied to the timer 36 to advance the drive roller 14 and the strip 12 a predetermined distance in accordance with the timing of the operation of the magnetic clutch 25 and the brake 26 in a preselected manner.
  • the amount of advance is less than the longest diagonal of the item 39.
  • the brake 26 is re-energized to stop the strip.
  • a one-revolution clutch 50 (FIG. 2) at a forming station is energized to drive, by means of an eccentric gear 51, a heat sealer 52 against the web in the region of a backup bar member 54.
  • This lateral seal pouch-forming operation initiated by the signal line 55 (FIG. 1) results in the individual pouches 49.
  • the temperature of the heat sealer 52 and the duration of its contact with the strip 12 is selected to provide a lateral seal as indicated at 56 in the strip 12 between the item 39 previously presented and the item 39 to be presented by a next operation of the air jet nozzle 44.
  • each pouch 49 is completed and a pouched web 57 is developed.
  • the particular type of item 39 illustrated is a relatively thin and flat faceplate member which is most easily sensed by a photodetector.
  • my invention is readily adapted to protect and store thick finished parts which do not have as large a surface as the faceplate member whereupon a mechanical feeler of the type illustrated at 58 develops a signal in a microswitch 60 to de-energize the valve 42 and initiate operation of the timer 30 to advance the folded strip 12.
  • the timer 30 is adjusted to provide smaller pouches 49, again to prevent loss of orientation.
  • a lower dancer roller 62 is provided.
  • This roller 62 is preferably of a circumference which will not unduly bend the items 39 within pouches 49 of the pouched strip 57 and of a mass which will assist the drive roller 14 in compressing the spring 20.
  • the bearing arrangement of the dancer roller 62 is such that in a lower position it activates a switch 64 as indicated by an arrow 65 to drive a takeup reel 66 by means of a motor 68.
  • the reel 66 is provided with large circumferential flanges 69 which maintain the pouched strip 57 in a relatively tightly coiled manner and closely engage the open ends of the pouches 49 to prevent loss of items 39. Moreover, as explained in my above-mentioned co-pending patent application, this containment enhances use of the pouches 49 to thereby simplify automatic presentation of the item to an assembler.
  • a simple arrangement for driving the reel 66 is by means of a magnetic clutch 70. Thus, the torque developed by the motor 68 need not be applied to the reel 66 except when the dancer roller 62 closes the switch 64. At other times the reel 66 may remain dormant.
  • the weight of the pouched strip 57 including the items 39 is usually sufiicient to tend to unwind the reel 66 particularly in view of the effective weight of the dancer roller 62.
  • FIG. 3 illustrates more clearly the lateral seals 56.
  • the seals 56 do not extend from the fold of the web to the cut edges. Instead, a space is left at both ends. The space near the fold is for the purpose of allowing an air jet supply means of the part dispenser to be inserted behind each item to selectively blow items 39 from the pouches 49 as they are needed. Also leaving one end of the pouch open allows removal of the parts without the addition of a slitting or other bag opening step which often turns out to be difficult to keep in calibration because of alignment problems of the polyethylene webs.
  • the gap of the lateral seal 56 near the mouth of each pouch is preferred to further enhance item removal.
  • a pouch forming and filling apparatus comprising:-
  • the lateral sealing means includes a heated member drivable against the folded strip by a one-revolution clutch with the clutch being energized only when the strip is stopped.
  • a pouch forming and filling apparatus comprising:
  • a pouch forming and filling apparatus as in claim 4 wherein said advancing means includes an intermittently operable drive roller for pulling the folded strip from a supply reel, with spring means being compressed thereby to reduce the size of a loop of the folded strip maintained by the spring means whereupon the reel supplies strip material to replenish the loop during a period substantially greater than the period of operation of said advancing means.
  • a pouch forming and filling apparatus comprising:
  • thermoplastic folded strip a reel for supplying a thermoplastic folded strip
  • a dancer roller means allowing said drive roller to drive intermittently the folded strip faster than it is pulled from said reel;
  • an air nozzle operable to move the item from said platform into the folded strip within the spread portion developed by said arm;
  • heater means for developing a lateral seal above the inserted item after each advance with the lateral seal leaving a substantial opening adjacent to the fold and forming thereby a pouch to restrict motion of the item therein;
  • a pouch forming and filling method comprising the steps of:
  • a pouch forming and filling methdd comprising the steps of:
