  • the numeral designates generally a conveyor which is seen to support bags B and B which are located in longitudinally spaced apart relation as by a gap therebetween.
  • This gap is described in greater detail hereinafter. Essentially it stems from the fact that the bags are reeled faster than they are advanced on the conveyor 20.
  • the conveyor 20 is of the vacuum type consisting of a screen or foraminous belt sliding over an apertured suction'box. Upstream of the portion of the conveyor 20 shown in FIG. 1 are located conventional folding and cutoff devices (not shown).

  • a gripper 24 is provided on the adjacent 1 end of the picker 23 which is adjacent the mandrel 21 and grips an edge portion of the bag B after the same has been completely reeled.
  • Retraction of the picker mechanism 23 positions the reeled bag under a tamper 25 which reciprocates in a direction parallel to the pre- 20 determined path of the conveyor 20 and tamps the reeled bag into a carton 26 e and incident thereto flattens the same so as to develop the desired flat folded configuration of bag.
  • FIGS. 2-9 it will be seen that a second mandrel 27 is depicted schematically and that both the mandrels 21 and 27 are rotatably mounted on a mandrel pivot arm 28 which is rockably mounted on a cross shaft 29 (also depicted schematically but which will be described hereinafter with reference to FIG. 10).
  • a mandrel pivot arm 28 which is rockably mounted on a cross shaft 29 (also depicted schematically but which will be described hereinafter with reference to FIG. 10).
  • FIG. 2 it is to be noted that the bag B has been completely reeled whereas in FIG. 1 the bag B is still in the process of being wound.
  • FIGS. 4 and 5 a subsequent stage of operation is shown where the bag B previously wound on the mandrel 21 has been stripped therefrom and is ready for tamping into the carton C. Meanwhile the bag B has been almost wound on the mandrel 27.
  • the mandrels are shown in the process of being indexed, i.e., oscillated to move the mandrel 21 upwardly into tangency (as at 21a in FIG. 4) with the conveyor 20.
  • the mandrel 27 is also shown in a position intermediate the ends of its oscillatory path no longer being approximately tangent to the conveyor 20 as it was in FIG. 2 but not quite in the stripping position as it is in FIG. 6.
  • a given cycle of operation includes reeling of one mandrel while stripping the second, moving the wound mandrel to the stripping position while moving the stripped mandrel to the winding position, reeling the second mandrel while stripping the first, and finally moving the second to the stripping position while moving the first back to the winding position.
  • the stripping positions for both mandrels is the same (compare FIGS. 2 and 6) while the winding positions are different athough in both cases there is approximate tengency to the conveyor 20 (again compare FIGS. 2 and 6).
  • pulleys 30 and 31 are mounted on the mandrels 21 and 27 respectively and through drives 32 and 33, respectively, derive rotational power from pulleys 34 and 35.
  • the pulleys 34 and 35 are fixed to the cross shaft 29 and are coupled, respectively to gears 36 and 37.
  • input to the gears 36 and 37 can be achieved from a variety of indexing mechanisms and for that purpose one such is schematically represented by the numeral 38, this, along with the cross shaft 29 being operatively associated with the frame generally designated 39 (see FIG. 1).
  • the unsupported or stripping end of the mandrels is equipped with an end portion 40 having a cutout 40a which provides an unsupported portion of the reeled bag for gripping by the gripper 24.
  • Arcuate slots in the end portion 40 permit rotary adjustment of the end portion 40 (via bolts 40b) so that the cutout 40a is properly aligned with the gripper 24.
  • the mandrels 21 and 27 are equipped with air passages or apertures 42 which are adapted to be in confronting relation with the innermost convolution or wrap of a bag being reeled.
  • the air passages 42 communicate with an air manifold 43, the purpose of which is to selectively apply vacuum or pressure to a given mandrel.
  • the air passages 42 are subjected to vacuum, i.e., the air pressure therein is reduced to below atmospheric so as to cause the bag to be readily transferred from the conveyor 20 to the mandrel in the winding position, viz., the position of the mandrel 27 in FIG. 2.
  • the mandrel Toward the end of the reeling cycle, the mandrel has the air passages thereof subjected to air pressure, i.e., to a pressure greater than atmospheric so as to facilitate the stripping of the reeled bag axially off of the mandrel.
  • air pressure i.e., to a pressure greater than atmospheric so as to facilitate the stripping of the reeled bag axially off of the mandrel.
  • the pressure air flowing out of the passages 42 in effect, provides a lubricant facilitating the stripping movement.
  • the mandrel pivot arm 28 is equipped with a banana-shaped fitting 44 (see FIG. 11) which is coupled to the two air manifolds 43 and 43a associated with the mandrels 21 and 27.
  • the fitting 44 is in sliding, generally sealed relationship with a stationary manifold plate 45 resiliently attached to the frame 39 (see FIG. 13).
  • the plate 45 has bores 4648 provided therein.
  • the bores 46 and 48 are coupled to a source of vacuum (not shown) while the intermediate bore 47 is coupled to a source of compressed air (also not shown).
  • one mandrel is coupled to a vacuum (when that particular mandrel is in the reeling position) while the other mandrel is coupled to a source of compressed air while that mandrel is in the stripping position.
  • both mandrels assume the same position for stripping, the stripping position being intermediate the ends of the arcuate path which brings the respective mandrels into approximate tangency with the conveyor 20.
  • the fitting 44 is equipped with bores 49 and 50 as can be seen best in FIGS. 12 and 13. As seen in FIGS.
  • the mandrel 21 is in the stripping position, i.e., away from the conveyor 20. Its associated bore 49 in the fitting 44 is aligned with the pressure passage 47.
  • the mandrel 27 is in the reeling position, i.e., generally tangent to the conveyor 20. Its associated bore-50 in the fitting 44 is aligned with the vacuum passage 46.
  • the bore 49 is aligned with the vacuum passage 48 and the bore 50 associated with the mandrel 27 is aligned with the pressure package 47.
  • FIG. 15 includes a plurality of graphs setting forth the timed relationship of the various steps and apparatus employed.
  • the uppermost graph is seen to be designated mandrel No. 1 winding velocity and has to do with the surface speed of the mandrel 21.
  • the third curve from the top shows the pattern of velocity or surface speed changes in the other mandrel 27 (designated No. 2 mandrel).
  • the third curve shows no rotational velocity of the mandrel No. 2 during the time mandrel No. 1 is in the winding mode.
  • This speed is set to be slightly faster than the linear speed of the conveyor 20 so that the outer convolutions of the reeled bag are relatively tight.
  • the speed at pickup is somewhat slower than the linear speed of the conveyor 20. This insures that the innermost convolution or the first wrap around the mandrel will be relatively loose so as to insure easy removability.
  • Reeling of the bag generally completes as the mandrel No. 1 reaches the deceleration portion of its rotation approximately the third quarter of the cycle.
  • the gap G is developed between the bags B and B on the vacuum belt of the conveyor 20 because the mandrels wind at a rate greater than the rate the bags are being carried on the conveyor 20.
  • the indexing device 38 driving the mandrels provides an acceleration period, a constant velocity period, a deceleration period, and a non-rotational period. More particularly, the bags are picked up by the vacuum in the reeling mandrel during the acceleration period, but at a point where the velocity of the surface of the mandrel is below the velocity of the bag on the conveyor 20. This allows each bag to be picked up without tension on the bag. Pickup occurs after the time vacuum is applied but before the mandrel reaches its constant velocity mode.
  • the velocity of the surface of the mandrel continues to increase to a value greater than the velocity of the vacuum belt conveyor 20 and the bag is caused to slip on the conveyor 20 to pull the bag being wound ahead of the next bag in the stream. Since the constant velocity period of rotation of the mandrel is at a greater velocity than the vacuum belt velocity, the bags are wound under tension for all but the first revolution of the wind.
  • the diameter-of the mandrel, the number of convolutions of wind and the pickup point are all designed to position the tail of the bag on top of the mandrel under the wiper brush 22 when the mandrel stops rotating in the strip position.
  • the mandrel No. 1 is moving to the pickup position. Thereafter for about 240, the mandrel No. 1 is in a dwell position for the winding or reeling of a bag. The next approximate 120 sees the mandrel being indexed to the strip or removal position, after which there is another substantial dwell period of about 240 for the actual stripping of the reeled bag from the mandrel.
  • the vacuum condition exists relative to the apertures 42 during the entire winding or reeling portion of the cycle for so long as the mandrel 21 is in the wind position because at that time the bore 49 is aligned with the passage 48.
  • the bore 49 in the fitting 44 is aligned with the intermediate bore 47 so as to deliver compressed air to the passages 42.
  • the mandrel is subjected to vacuum while the mandrel is subjected to air pressure for a period shortly before and during the stripping.
  • the numeral 51 generally designates the actuator for the picker mechanism 23.
  • the picker mechanism is essentially a reciprocating mechanism which moves the gripper 24 into and out of engagement of a cantilevered edge portion of the reeled bag.
  • the picker is slidably received within a guide 52.
  • the numeral 53 designates the movable jaw of the gripper 24 while the numeral 54 designates the stationary jaw.
  • the movable jaw 53 is coupled by means of a cable 55 to a cam follower arm 56 which carries a cam follower 57.
  • the cam follower arm is seen to be mounted on the picker mechanism 23 and moves therewith. Normally, the movable jaw 53 is urged into gripping contact with the stationary jaw 54 by means of a tension spring 58 extending between the jaw 53 and a spaced portion on the picker mechanism 23. However, as the picker mechanism advances axially toward the mandrel in the stripping position, the cam follower 57 comes into contact with a rotating cam 59.
  • the rotating cam 59 is programmed so that just as the gripper 24 is about to engage the edge of the reeled bag, the cam follower arm 55 is rocked so as to temporarily open the jaws 53-54. Thereafter, the jaws snap shut about a portion of the reeled bag and remain in that position until the picker mechanism 23 is virtually completely retracted, i.e., until the cam follower 57 engages a fixed cam surface 60. This results in opening the jaws 53-4 so that the tamper 25 can perform its function in separating now stripped reeled bag from the gripper 24 and into the carton 26. v
  • the timed sequence of the picker mechanism 23 and gripper 24 are seen on the fourth and fifth curves (counting from the top) of FIG. 15. It will be appreciated that each of these functions is performed twice each cycle of 720 as designated. Thus, as the mandrel No. 1 has been indexed to the stripping position (reaching that at about 480) the picker mechanism 23 is almost adjacent the end of the mandrel No. 1. On the fifth curve relating to the gripper 24 and in the portion between 450 and 540, two sinusoidal curves are seen which are placed in proper timed relation to the other curves. The first curve shows the opening of the gripper while the second curve shows the closing of the gripper on the bag reeled on mandrel No. l.
  • the last curve on FIG. 15 relates to the tamper 25.
  • the apparatus preferred for the achievement of the operation of the tamper is also seen on FIG. 14 where the numeral 61 generally designates the tamper guide and the numeral 62 designates the tamper actuator, i.e., the mechanism which controls the reciprocation of the tamper in accordance with the timed program depicted on FIG. 15.
  • the tamper goes through two complete reciprocations for each cycle.
  • the times contemplated by the graphs in FIG. 15 which are generally to scale, are of the order of 0.8 seconds for a complete cycle of 720.
  • FIG. 2 shows the side view of FIG. 2 shows the vacuum belt of the conveyor 20 and the lower pulley 63 associated therewith and with the mandrel pivot arm 28 and its pivot point 29 (actually the axis of the cross shaft 29). This is seen to the left.
  • the mandrel 21 has completed the winding of the bag B and the mandrel 27 has just picked up the bag B.
  • the front view in FIG. 3 shows the picker 23 gripping the bag via the gripper 24 with the tamper 25 in a raised position. During this period of operation, the vacuum is on for the mandrel 27 and the air pressure is on for the mandrel 21.
  • the wiper 22 is engaging the top of bag B on mandrel 21 and holding the tail of this bag in place on the mandrel.
  • the bag carton 26 is shown below the tamper in FIG. 3.
  • FIG. 4 shows the showing is slightly later in the cycle from that of FIG. 2 the bag having been removed from the mandrel 21 and the bag B being partially wound on the mandrel 27.
  • the mandrel pivot arm 28 is in the process of being pivoted upward to put the mandrel 27 in position to pick up a subsequent bag B from the vacuum belt conveyor 20.
  • the front view as seen in FIG. 5 shows the picker 23 moved all the way to the right and having released the bag B previously wound on the mandrel 21 against a set of stripper bars 64.
  • FIG. 5 also shows the tamper in two positions. The solid line position shown is just after the bag B has been released by the gripper 24 of the picker 23.
  • FIG. 6 the side view is generally the same as in FIG. 2 except that the mandrels are in the reverse position.
  • the picker 23 is shown before the bag B is gripped instead of just after gripping as is the case in FIG. 3.
  • FIG. 8 the side view is generally the same as FIG. 4 except the positions of the mandrels are reversed and the same applied to the showing in FIG. 4 as contrasted to that of FIG. 5.

  • a method of packaging flexible plastic bags comprising the steps of sequentially advancing bags along a predetermined path, reeling each bag upon itself about a mandrel disposed generally tangent to said path, rotating said mandrel at a surface speed at the beginning of said reeling lower than the speed of the bag in said path to provide a loose wrap on the mandrel and thereafter before reeling is complete increasing the surface speed of the mandrel to greater than that of the bag in said path, gripping an edge portion of the reeled bag and moving the same transverse to said path to clear said path and thereafter releasing the grip thereon, and tamping said reeled bag into a case by movement parallel to said path.
  • a method for the rapid packaging of refuse bags comprising advancing bags sequentially along a predetermined path while simultaneously indexing a pair of spaced apart mandrels into and out of approximate tangency to said path whereby when one mandrel is approximately tangent the other mandrel is spaced from said path, temporarily stopping said indexing to cause said mandrels to dwell in respective positions and during said dwell reeling a bag on the approximately tangent mandrel while stripping a previously reeled bag from the other mandrel in the direction transverse to said predetermined path and generally flattening said stripped bag into a case by movement in a direction parallel to but spaced from said path and during the indexing of said mandrels.
