Definitions

  • ABSTRACT In an operation for filling containers into a cardboard box, initially a feed mechanism supplies a folded box to an inclined support surface and an angle guide displaceably mounted on a bell crank engages and opens the box. As the angle guide opens the box it displaces a gripping tip into contact with the box so that the two members combine in effecting its opening. A swivel packer supplies the containers to be packed into a guide hopper.
  • the guide hopper is movably positionable in the direction of the height of the box and is located above the box on the support surface and guides the containers into the box.
  • the hopper is formed of side walls and guide walls pivotally attached to the lower ends of the side walls. The guide walls are biased inwardly into the outlet path from the guide hopper for holding the containers in the hopper and, when the guide walls are spread apart, the containers can slide downwardly out of the hopper into the box.
  • the present invention is directed to a device for opening up folded cardboardboxes and filling containers, such as soft containers into the opened'box'and, more particularly, it is directed to adevice for opening up the folded boxes and for guiding the containersinto the opened box.
  • the problem often develops that the soft or yielding containers for the liquid must bepackedin larger receptacles, forexample in plastic boxes or cartons.
  • the cartons consist of printed corrugated cardboard and hold several rows of the soft containers.
  • the opened or set up cardboard boxes are positioned on a conveyor inclined to the horizontal and, by means of known cam shafts, the boxes are located in predetermined positions under swivel packaging machinesso that a row of soft containers can be introduced into a cardboard box in the holding position. If five rows of soft containers are to be housed in the cardboard box, the box is supported on an intermittently operating conveyor which is associated with five cams formoving the box into five different positions for receiving the five rows of containers.
  • the present invention is directed to opening or setting up the cardboard boxes and to filling the soft containers into the boxes.
  • a disadvantage of these known devices is the considerable size of thedevice, that is the cardboard box must frequently cover a considerable distance as his converted from its folded state into its opened state.
  • swivel packer di- 2 rects the soft containers, received from a conveyor, into the shipping recepticles.
  • the swivel packer transports thesoft containers froma conveyor toapacking machine in which a shipping cartonis positioned on another obliquely arranged conveyor.
  • the swivel packer is pivotally mounted onia frame and isrdisplaced bya pneumaticallyoperated means.
  • the swivel packer includes a swivel tunnel head, side pl.ates, an end stop and a pivotwhichextends in the inlet direction of the conveyor supplying thecontainers, and a curved guide plate located below theside platesfor guiding the bottoms of the containers.
  • a primary object of the present invention is to provide a device for setting up or opening folded cardboard boxes and for filling containers into the cardboard boxes so that the setting up and filling operations can be carried out in a reliable manner and at high production rates.
  • the invention is distinguished by the arrangement for introducing a folded cardboard box onto a support surface where it is opened up and positioned under a guide hopper which can be lowered into the box for properly filling it with the containers.
  • a guide hopper which can be lowered into the box for properly filling it with the containers.
  • thesoft containers are guided from the swivel packer to a position where they can be properly deposited into the boxQWith the guide hopper it is possible to position the containers so that they do not contact the upper edge of the box as they are lowered into position or they do not land on an adjoining soft container already positioned within the box.
  • the guide hopper is supported so that it can be lowered into the cardboard box forming a guide for the containers as they are dropped into position. Due to the combination of the membersfor opening a cardboard box and for feeding containers into the cardboard box the problems previously experienced are reliably and safely solved without the need for cumbersome controls.
  • the operation of opening the folded cardboard box is effected by the pressing action of an angle guide mounted on a bell crank which is directed against one folded end of the box and, as it opens the box, the angle guide cooperates with a pivotally mounted lever incorporating a gripping point or tip which combines with the angle guide in opening the box.
  • the lever with its gripping tip assumes a certain position in engagement with one side wall of the box and as the angle guide opens the box the tip assures that one side wall is safely lifted from the other.
  • the gripping tip penetrates into one side wall and pulls it to the outside as the lever pivots to its original position.
  • the gripping point or tip is movably displaceably mounted in the free end of the lever, that is the end opposite the end at which it is pivoted. Normally, the gripping tip is retracted within the lever, however, as the angle guide opens the box it contacts the lever and causes the gripping point to project outwardly from its free end.
  • the gripping tip can consist of one or a number of juxtaposed and/or superposed pegs of round or square cross-section or of one or several needles. To assure that the gripping point or points engage the side wall of the cardboard box at the correct time, the angle guide and the lever are arranged to control the movement of the gripping point.
  • the gripping point which advantageously is mounted on the lever by means of a linkage, is movably displaced by a cam control, for example, by a control wheel mounted on the angle guide which controls the movement of the linkage supporting the gripping point and also displaces the lever in such a way that it is lifted in a predetermined manner from the folded cardboard box on which its free end rests.
  • the operation of the bell crank and also of the lever can be effected in a simple and known manner by pneumatic or hydraulic drives which are very reliable and require a minimum of attendance.
  • Another feature of the invention is the arrangement of the guide hopper or funnel for directing the soft containers into the proper position in the cardboard box.
  • the guide hopper is formed of side walls secured to a holding arm so that the hopper can be moved upwardly and downwardly in the direction of the height of the container. At the lower ends of each of the side walls a pivotally mounted guide wall is provided which is biased inwardly into the path of the containers from the hopper.
  • the arrangement of the hopper is notable by the manner in which the guide walls are arranged.
  • the force directing the guide walls inwardly can be provided by weights, springs or lever so that the outlet from the hopper has a smaller rectangular surface or area than its inlet through which the soft containers are introduced into it from the swivel packer.
  • the device for setting up the folded cardboard boxes and for filling the soft containers into the boxes eliminates the problems previously experienced, and a compact and safe apparatus is afforded which can carry out the entire operation in a relatively small space.
  • FIG. 1 is a side elevational view which illustrates schematically the device embodying the present invention
  • FIG. 2 is a top view of the device taken along the line AA in FIG. 1;

  • An intermittently operated conveyor 4 is provided for removal of the assembled and filled cardboard boxes.
  • Located below the conveyor 4 is an inclined member 50 on which the folded cardboard boxes 3' are stacked.
  • a feeding mechanism 6 Positioned below the inclined member 50 is a feeding mechanism 6 for directing individual ones of the folded cardboard boxes 3' from the inclined member upwardly into position to be opened. Therefore, it can be noted from FIG. 1 that the cardboard boxes are moved upwardly into a filling station positioned above the conveyor and the soft containers 2 are dropped downwardly into the filling station.
  • a frame not designated with a reference numeral provides a pivot 11 on which a swivel tunnel head 12 is mounted.
  • a pneumatic cylinder 13 Positioned on the frame is a pneumatic cylinder 13 with its piston rod connected to the tunnel head 12 so that the head swivels about the pivot 11 in response to the movement of the piston rod in the cylinder 13.
  • side plates 14 and 15 Arranged about the lower end of the tunnel head 12 are side plates 14 and 15 which have their longitudinal direction extending parallel to the pivot 11 and the side' plates represent a lateral guide for the soft containers 2 held in the swivel packer 1.
  • operating arms are arranged for control switches, not shown.
  • the containers 2 are introduced to the swivel packer by a conveyor, not shown, and the leading soft container commences the swivel operation over an end stop.
  • a curved guide plate 16 is secured to the frame.
  • the guide plate extends in the longitudinal direction of the side plates and its curvature extends transversely of the inlet direction.
  • the length of the arc of the guide plate 16 is equal to the arc length traversed during the rotational movement about the pivot 11 reduced by the width of the swivel body, that is, the distance between the side plates 14 and 15. 1
  • the intermittently operable conveyor for the assembled cardboard boxes 3.
  • a cardboard box 3 in the opened condition bears against a first cam 17 of a cam shaft 18.
  • the inclined position of the conveyor 4 is determined by the angular position of the tunnel head 12.
  • the angle of traverse is illustrated in FIG. 2 by the two broken lines which extend through the pivot 11. In the position of the broken line angularly displaced from the vertical, the space between the side plates 14 and 15 is aligned with the space in the cardboard box 3 into which the containers 2 are to be introduced.
  • the assembled box 3 rests on an inclined plate or surface member 19, note the arrangement as shown in FIGS. 2 and 3.
  • a gap or space is provided between the first cam 17 and the adjacent edge of the inclined plate 19 through which a folded cardboard box 3' can be introduced into the filling station above the conveyor 4 by means of the feeding mechanism 6 which is actuated by a pneumatic drive 20.
  • a guide hopper 21 is shown in FIG. 1, partly in broken lines, below the pneumatic cylinder 13 and is supported on holding arms 22 which effect a raising and lowering movement of the hopper by way of pneumatic drives, not shown.
  • FIG. 2 an angle guide 23 is shown, though it does not appear in FIG. 1, which is secured to abell crank 24.
  • the bell crank is pivotally mounted intermediate its ends about the axis 27 and its end opposite the end connected to the angle guide is, in turn, connected by a piston rod 25 to a pneumatic cylinder 26.
  • the piston rod 25 When the piston rod 25 is moved by the cylinder 26, the bell crank can be pivoted between a first position, shown in full line, and a second position shown in dashed lines.
  • the angle guide is displaced to the dashed line position when the cardboard box 3 is filled with the soft containers and is displaced from the filling station.
  • FIG. 3 The manner in which a cardboard box is opened from its folded position is shown in FIG. 3 where the angle guide 23 is located in an intermediate position between the two end positions shown in FIG. 2.
  • the angle guide 23 has just engaged the lefthand outer edge of the partly unfolded cardboard box and is pressing it in the righthand direction.
  • the roller 28 mounted on the outside of the angle guide and made, for example, of polytetrafluoroethylene, presses against a linkage 29 and rolls along a contact surface 31 on a swivel lever 32.
  • the linkage 29 is pivotally supported on the lever 32.
  • a tension spring 33 is connected to the lever and to the linkage which biases the gripping tip 30 inwardly of the free end 36 of the swivel lever, that is the opposite end of the lever from the end which is pivotally mounted.
  • the contact of the roller 28 with the linkage 29 causes the gripping tip 30 to project outwardly from the free end of the lever. Therefore, as the bell crank 24 moves the angle guide 23 in the direction of the arrow 34, the swivel lever is caused to be displaced in the direction of the arrow 35.
  • the lever 32 moves in the direction of the arrow 35 its free end 36 moves upwardly as viewed in FIG. 3.
  • FIG. 4 a sectional view is shown through the guide hopper 21.
  • the guide hopper 21 In this figure. only three of the four side walls are shown, that is the two longitudinally extending walls 37, 38 and the rear end wall 39. At its lower end each of the side walls has a pivotally connected guide wall 37', 38' and 39'. Weights 40 secured on levers are connected to the guide walls and bias them inwardly into an inclined position in the path of the outlet of the containers from the hopper.
  • the device in accordance with the present invention, works in the following manner:
  • the containers 2 are conducted by a conveyor, not shown, into the tunnel head 12 passing between the two side plates 14, 15.
  • the forwardmost soft container will actuate the contact, not shown, which controls the pneumatic cylinder.
  • the pneumatic cylinder swivels the tunnel body 12 about the pivot 11 in the clockwise direction, as viewed in FIG. I.
  • the bottom of the swivel packer 1, that is the guide plate 16 is displaced from below the containers 2.
  • the guide hopper 21 is in a lowered position, that is below the position shown in FIG. 1, so that the soft containers sliding past the curved guide plate move into the hopper between its side walls 37, 38, 39.
  • the articulated guide walls 37', 38", 39 ensure suitable guidance for the containers into the position they are to assume in the bottom of the box 3.
  • the guide walls 37, 38, 39' are spread apart and the row of soft containers slides downwardly and is safely positioned on the bottom of the cardboard box 3.
  • the box is displaced downwardly along the inclined surface 19 to receive another row of containers until the bottom of the box is filled with the containers. When the box is completely filled it is released by the cam shaft and slides, in a manner not shown, to a delivery station.
  • the setting up or opening operation can be performed which is illustrated best in FIGS. 2 and 3.
  • the angle guide 23 is pivoted by means of the bell crank 24 actuated by the piston rod 25 and the cylinder 26 about the axisof rotation 27 in the direction of the arrow 34, note FIG. 3.
  • the lever 32 with its gripping tip 30 retracted, rests with its free end 36 on the upper side wall of the cardboard box.
  • the roller 28 on the angle guide contacts the opposite end of the linkage 25 from the gripping tip and pushes the tip 30 outwardly of the free end 36 of the lever and into the upper side wall of the cardboard box.
  • the conveyor 50 While a support member can be used for the folded boxes 3, the conveyor 50, as shown in FIG. 1, supports the folded boxes and the conveyor can be either of the chain or belt type.
  • the conveyor 50 during the downward movement of the feeding mechanism 6, moves over freewheeling means by a multiple of the thickness of the cartons 3' in the rightward direction as shown in FIG. 1. This movement ensures the proper positioning of the folded boxes 3'.
  • the advantage of this arrangement is that, when the support surface for the folded boxes is completely filled, no die or other construction element pressing the boxes 3' down has to be removed. Further, the need for a separate feeding mechanism is avoided.
  • the opening action exerted by the angle guide 23 can be directed against the righthand wall (FIG. 2) of the surface member 19 acting as a supporting wall for the opposite end of the box 3.
