Definitions

  • This invention relates to apparatus for applying the closures of the type disclosed in Canadian Patent 738,149 issued July 12, 1966, entitled "Bag Closure Fastener”.
  • the present invention provides apparatus which automatically applies bag closures to the neck of a bag.
  • the closure applying mechanism operation is delayed until the bag is in position at the bag applying station at which time it is gathered and the bag closure is applied. This division of the two operations does not delay the application of the closure.
  • Figure 1 shows a general perspective view from the front of an apparatus, indicated generally at 10, mounted beside a conveyor 11, on which packages 12 are shown in -dotted outline.
  • the apparatus comprises a housing with end plates 13 and 14, a top plate 15 and spaced transverse plates 16 and 17 which serve to space the end plates and support the operating mechanism.
  • a motor 18 is mounted on end plates 13 under the housing.
  • Motor 18 may be of the constant or variable speed type depending on the particular application.
  • Motor 18 is operably connected either by gears or drive chain, not shown, to a shaft 19.
  • Shaft 19 is rotatably supported on end plates 13 and 14 and through gears 20 and 21, and serves to drive a brush 22.
  • a second brush 23 on shaft 24 is also connected to shaft 19 through a chain drive 25.
  • Brushes 22 and 23 rotate in opposite directions and serve as a bag neck orienting mechanism which serves to flatten an approaching bag neck which has to be flattened.
  • a closure applying station On front plate 17 a closure applying station is provided and guide channel defined by a pair of spaced-apart plates 30 and 31 to feed the closures such as 32 towards the closure applying position. Plates 30 and 31 are provided with openings 33 and 34, respectively.
  • a finger 35 is pivotally mounted and urged by a spring 36 to pass through opening 33 and engage the closures such as 37 therein.
  • the lowermost end of the closure guide channel is positioned adjacent the bag applying station so that the lowermost closure 37 is positioned in the manner shown in Figure 4.
  • the closure applying station comprises a pair of spaced-apart free wheels 38 and 39 mounted on a pair of arms, one of which is shown at 40, pivotally mounted on front plate 17.
  • the arms such as 40 are biased downward by springs such as 41 so as to urge wheels 38 and 39 into engagement with respective aligned serrated drive belts 42 and 43.
  • Belts 42 and 43 are each driven by a driven wheel, such as 44 and free wheel 45 which are shown in the drawings.
  • Belt 43. is similarly driven.
  • a tensioning pulley 46 is also provided as shown to maintain the correct tension on the respective belts.
  • Wheels 44 and 45 are mounted on shafts 50 and 51 and wheels 44 are connected through a chain drive 52, and gears 54 and 55 to motor 18.
  • closure clearing arm 57 is mounted to follow arms 56 around as they rotate.
  • arm 56 follows a greater locus than the radius of wheel 45 so that it sweeps past the opening in the aligned closure 32.
  • Arm 57 serves to sweep out any closures on bags which may block or jam the motion.
  • Arm 60 pivots about shaft 61 and is biased into a downwardly extending attitude by a spring 62.
  • Shaft 61 extends through the front and rear plates 16 and 17 and is connected to a rod 63.
  • Rod 63 is biased downwardly by a spring 64.
  • the free end of rod 63 engages a stepped slot 65 in plate 66.
  • Plate 66 is stepped on its underside for engagement with a correspondingly stepped plate 67 on a shaft 68.
  • Shaft 68 is slidably mounted on bracket 69 and pivotally mounted shaft 70. From shaft 70 a finger 71 extends downwardly and is also pivoted at 72. A spring 73 engaged with a collar 74 on shaft 68 biases shaft 68 into tendency to move about pivot 70.
  • a further finger 80 is connected to a further arm 81 and slot 82 on shaft 68. Finger 71 extends into the locus of a cam 75 of a round plate 76.
  • Plate 76 is mounted on a shaft 85 which is connectable through clutch 53 with motor 18. Finger 81 is in an "at rest” position engaged with a pin 99 on one plate of clutch 53. This engagement maintains disengagement of the clutch 53.
  • wheels 44 are constantly driven and the remaining motor operated parts are inactive.
  • Eccentrically mounted on plate 76 are two pivotally mounted arms 90 and 91.
  • Arm 90 is connected to arm 92 which pivots' about 93.
  • a closure advancing finger 94 is pivotally mounted and biased into closure engagement with a spring 95.
  • Arm 91 is connected to pivotal shaft 96 on the front end of which a knife 97 is mounted to move into and out of a cutting position.
  • brushes 22 and 23 are conical in form and are mounted in the travel of the bags to which the closures are to be applied.
  • One such bag is indicated at 100.
  • arms 90 and 91 are caused to rotate. As arms 90 and 91 rotate the particular arrangement illustrated ensures that knife 97 is moved into its cutting position and sever the adjacent connection between closures.
  • arm 92 As plate 76 continues to rotate arm 92 is caused to pivot about 93. Finger 94 is urged downwardly and advance the next closure down into a bag receiving position.
  • the sweeper arm 57 clears any objects from its path as it passes.
