Bottom Filling Patents (Class 53/242)
  • Patent number: 10513357
    Abstract: An apparatus for closing a flap on an open end of a box may include a device having a slot and a mechanism operable to provide a relative motion between the slot and the flap. The relative motion may cause the flap to be received into the slot and the flap to be reoriented to a closed position. A method of closing an open end of a box being conveyed downstream, with the open end facing transversely, may include two operations. With a trailing minor flap on the open end being held in a substantially upstream-pointing open position, the opposing leading minor flap on the open end may be closed from a substantially downstream-pointing open position to a substantially upstream-pointing closed position. With the leading minor flap being held in the closed position, the trailing minor flap may be closed from the open position to a substantially downstream-pointing closed position.

  • Patent number: 8650842
    Abstract: The present invention relates to a glove packing apparatus for packing gloves into a box, and to a method of packing gloves into a box, particularly to the packing of disposable medical gloves. A glove packing apparatus (1) for packing gloves into a box comprises a receptacle (26) for forming a stack of gloves to be packed, the receptacle having a perimeter wall (24, 25) for containing a stack of gloves, a floor (22) within the perimeter wall for supporting the stack of gloves, and an opening (27) opposite the floor into which additional gloves may be added to during stacking of gloves. The floor (22) is movable relative to the perimeter wall (24, 25), so that, in use, the floor may be moved relatively away from the receptacle opening (27) so that as gloves are added to said stack of gloves, the perimeter wall continues to contain the stack of gloves. The floor (22) may then be moved relatively toward the opening to remove the stack of gloves from the receptacle (26).

  • Patent number: 7104026
    Abstract: A packing method and system are disclosed which system includes a first platform having a product support surface for supporting a product and a second platform for supporting a box into which the product is to be packed. After a box is received on and secured to the second platform, the second platform is rotated so that the open top of the box faces the first platform and moved toward the first platform until the box substantially surrounds the product on the product support surface. The first and second platforms are then rotated simultaneously so that the product is transferred from the product support to the box, and the full box is discharged to a discharge conveyor.

    Abstract: The invention relates to a system and process for loading containers with formed product. The system includes a container transport assembly, a product transport assembly and a combined transport assembly. The container transport assembly advances and positions the containers along a first path towards a loading zone. The product transport assembly advances and positions the formed product along a second path towards the loading zone. The combined transport assembly defines a third path away from the loading zone. The first path and the second path share at least one common direction of travel and each path is in part independent of the other and each path is in part merged with the other. The formed product is loaded into the containers as the paths merge. Thereafter, the containers with formed product loaded therein are advanced away from the loading zone along the third path.

    Abstract: A container having four vertical sides, a top side and a bottom side, the six sides being connected to form a cube. The six sides are joined at the edges of the cube, and the juncture of one vertical edge with two upper edges forms a slanted surface. A pouring spout is mounted on the slanted surface and is inset from the planes of the adjacent sides so that it does not interfere with nesting and stacking. A handle is attached to the top side, at approximately its center, for carrying purposes, the handle being foldable to a flat position to facilitate stacking. The container is formed by cutting a blank from a flat sheet of relatively stiff material, and folding the blank along creases to form a closed container. The top and four sides are folded and sealed first, the pouring spout is installed, the container is filled through the open bottom side, and then the bottom side is folded and sealed.

    Abstract: A horizontal force moves a tape-automated-bonded (TAB) carrier along a first horizontal surface so that the leading edge of the TAB carrier is elevated above a second horizontal surface located beneath the open bottom area of the stacking magazine. After the center of gravity of the TAB carrier has passed a pivot line, the TAB carrier is pivoted about the pivot line by the force of gravity and assumes a horizontal position within the open bottom area of the stacking magazine. If the stacking magazine contains one or more previously-loaded TAB carriers, the TAB carrier being inserted into the open bottom area of the stacking magazine pushes upwardly against the lower surface of the lowest previously loaded TAB carrier so that the weight of the one or more previously loaded TAB carriers also helps to pivot the TAB carrier being loaded about the pivot line.

  • Patent number: 4481752
    Abstract: A method and a machine for loading articles into cases utilize indexed rotary movement of a carousel device having a series of angularly spaced platforms, with a case holding device directly above each platform. Articles are pushed onto one of the platforms at an infeed station, in the configuration they will take when packed, with an open-bottomed case held directly above. Then the platform and empty case are rotated to an offloading station, and the platform is raised up into the bottom of the case by camming action, in response to the rotation. At the offloading station, flap folders push the minor bottom flaps of the carton up into closed position, and the case is pushed off the platform onto a conveyor, which also effects closure of the leading major flap up against the minor flaps. There may be three stations, the cases being drawn from flattened, stored configuration and gripped by the case holding device at a station following the offloading station.

    Abstract: A case packer for placement of loads through the bottom of a carton so as to accommodate loads of a type which cannot be dropped or placed into a carton from above or from the side. The apparatus includes a support plate mechanism mounted for elevational movement and supplied with individual case loads by a case conveyor. The cases themselves are delivered sequentially to a case packing station by a case conveyor. The plate mechanism is movable upwardly to locate the load within the downwardly open case. Flap engaging elements then fold opposed flaps beneath the plate mechanism and provide elevational support to the case and load within it. Plate shift means spreads the plate mechanism laterally from a position located between the load and the folded flaps to a position clear of the flaps. The plate mechanism can then be sequentially moved downward to clear the case before it moves outward from the case packing station.

  • Patent number: 4033094
    Abstract: Bobbins of yarn wound up on a winding device of a winding-up machine slide under gravity along a channel that maintains the orientation of the bobbins, both axially and in regard to the sense in which the yarn is wound, as determined by the winding device. Each bobbin dwells at a positioning device at the lower end of the channel through which a thrust member rises to carry the bobbin through an opening in the base of a container in which the bobbins are later carried away for further processing. The opening is normally closed by two flaps that lie edge to edge across the opening but are separated against spring action by the rising bobbin. The thrust member and plates carrying the flaps are so shaped that the flaps can immediately return to their closing positions beneath the bobbin when this has nearly wholly entered the container. The container may be inclined or have inclined base walls to enable the bobbins to pile up therein while always remaining in their initial orientation.
