Definitions

  • ABSTRACT Apparatus for handling thin walled containers includ ing a handling unit comprising a plurality of individual container holders each adapted to hold a container in upright manner therein, means maintaining the holders in spaced relationship and defining an endless path, means for moving the holders in said endless path, each of said holders being split vertically to de fine two parts which are relatively displaceable vertically from a holder closed position to a holder open position in which a container can be moved horizon tally into the upper holder part, and means for rela tively displacing vertically the holder parts of each holder from the holder closed position to the holder open position and for returning the parts to the holder closed position.
  • a particularly suitable adaptation for the invention is for handling containers which are not freestanding, or which. although capable of freestanding. are of flimsy material such that, for example, during filling they need additional support. Should the need arise, however, the apparatus can be used for handling any thi'nwalled container.
  • handling apparatus for handling thin walled containers
  • a handling unit comprising a plurality of individual container holders each adapted to locate and support a container therein, said holders being adapted to move in an endless path, and each including two or more parts which are capable of movement one relative to the other to open and close the holder.
  • the holders being mounted so that for each holder at least once during a complete cycle of movement along said endless path, the holder is closed to support a container therein, whilst some other opera tion is carried out in relation thereto and is opened to allow removal and/or insertion of the container.
  • the said endless path is preferably defined by a pitch circle of a horizontal rotatable table on which the holders are carried.
  • the holders preferably are each in two shells, an inner shell and an outer shell, in relation to the axis of rotation of said table, the inner and outer shells being capable of relative sliding movement, to a limited extent sufficient to open and close the holder, in a direction parallel to said axis of rotation of the table.
  • the outer shell is adapted to slide downwards exposing the inner shell and so that a container can be moved into a inner shell in a direction transverse to the axis of the table. In the subsequent closing of the holder, the outer shell slides upwards until it is in horizontal alignment with the inner shell.
  • the holder is preferably open for a sufficient proportion of the circular path of travel to enable one container to be removed in a transverse direction, and another container inserted.
  • Control of the movement of the outer shell relative to the inner shell may be achieved by means of a cam and follower arrangement.
  • a follower connected to each outer shell engages a common cam track extending circumferentially relative to the table.
  • each holder may be adapted to be raised whilst in the closed condition and holding a container, relative to the table.
  • each holder is provided with a raising ram which is actuated to perform this raising of the holder. Operation of each ram is synchronised with the rotation of the table and the filling of the containers.
  • the shells preferably define identical halves of a cavity shaped neatly to the outer shape of the container to be handled.
  • the handling apparatus preferably further includes a de-stacker for separating containers one by one from the bottom of a stack of nested containers, and empty container feed means for feeding the containers individually and synchronism to said container holders.
  • the apparatus may include transfer means for transferring containers from the holders to a combining sub-assembly wherein each container is combined with an outer cup.
  • Each container may pass through a washing and drying unit before being passed to the sub-assembly.
  • FIG. I is a sectional elevation of a holder forming part of the holding unit of the apparatus according to the invention.
  • FIG. 2 is a sectional plan taken on line AA of FIG. 1
  • FIG. 3 is a plan view of a de-stacker unit of the apparatus according to the invention.

  • FIG. 9 is a sectional elevation taken on the line C-C of FIG. 7.
  • FIGS. 1 and 2 a part of a rotatable horizontal holder table isshown in the drawings by the reference numeral 10 the table being rotatable about a vertical axis.
  • the containers are to be handled for filling.
  • the section through the table, FIG. I is taken at the peripheral region of the table and shows one container holder in co-operative relationship with a filling head 12 of known construction whereby a container in the holder may be filled, in this case with carbonated beverage,
  • the table 10 has a plurality of holders each as shown in FIG. 1, these holders being equally spaced around the periphery of the table 10.
  • Each holder comprises two shells 14 and 16 which together define a cavity 18 for a container of similar shape, the shells 14 and 16 defining identical halves of cavity 18 when the shells l4 and 16 are in the position shown in FIG. 1 which is the closed position.
  • the shell 14 is mounted on a block 20 secured to the table 10 so that shell 14 can slide relative to block 20 by the amount from the position shown in FIG. 1 until stop 22 on shell 14 contacts the top face of block 20.
  • the shell 14 is provided with a dove-tail section which engages in a corresponding slideway 24 (see in particular FIG. 2) defined in the block 20 to ensure that shell 14 is free only to slide vertically relative to block 20.
  • FIG. 2 Further slide bars 26 define a slideway for the shell 16 to enable this shell to slide vertically relative to block 20, but to a greater extent than shell 14 can slide on block 20.
  • shell 16 has a corresponding dove-tail sec tion 28 (see in particular FIG. 2) which engages between the bars 26.
  • Each holder is associated with a pneumatic ram indi cated at 30 which is for raising the holder upwardly so that the container in cavity 18 engages the filling head 12. This is the position shown in FIG. 1, i.e., ram 30 is extended.
  • Ram 30 is connected via its piston rod with the shell 16 and shells l4 and 16 and ram 30 rotate in unison with the rotation of the table 10.
  • each of the holder arrangements operates in a desired sequence of events whereby containers of the configuration which is the same as cavity 18 are loaded into the holders are then filled from the filling head 12 and tinally are removed from the holders for further process-
  • the filling head 12 rotates with the table 10 and filling is completed over a fraction of one complete revolution of the table.
  • the shells l4 and 16 are designed such that the top edges of the shells locate under a de-nesting ring on the container and by this means push the container into sealing engagement with the filling head. Thatis to say the body of the container does not take much if any stress due to the pressure with which the upper edge of the container is pressed to the sealing head.
  • the container in cavity 18 is removed with its contents and is held upright by suitable guide means.
  • the container is moved into a removing table which rotates in synchronism with the table 10.
  • the shells 14 and 16 remain in this position until a further empty container is placed in the half cavity defined by shell 14.
  • This empty container is held in the half cavity defined by shell 14 by suitable guides extending circumferentially of the table until such times as roller 32 engages another section of the cam track which causes shell 16 to lift up to the position in which the complete cavity is defined and the holder is closed.
  • the shells 14 and 16 remain in this position until the ram is actuated at which point the holder is raised as a unit to the sealing head 12 as indicated in FIG. 1.
  • the adaptation of the pneumatic ram 30 for raising the holder as a unit up to the sealing head enables a good seal between the container and the sealing head during the filling. This seal is necessary in the case of filling containers with carbonated beverage because if there is any pressure leak then there is a danger that the carbonation balance of the liquid will be destroyed.
  • this handling unit primarily is for handling containers and in particular is for handling containers which are not free-standing or containers of which the wall is of a very flimsy material and I the containers require to be filled underpressure because the adaptation of the cavity to the container outer shape provides that each container is supported against eternal pressure during filling. It is'not necessary that these containers be handled in this manner for filling operations.
  • containers have to be lidded then they could be handled by this apparatus and they would be moved up to a lidding head or a seaming head instead of a filling head as indicated in and described with reference to FIGS. 1 and 2 of the drawings.
  • This handling unit is extremely suitable for handling containers which are not free-standing as clearly would be containers of the configuration of cavity 18.
  • the arrangement enables the containers to be moved into the shell 14 in a direction transverse and removed similarly to the direction in which the shells l4 and 16 are slid apart.
  • a destacking unit for dropping one-by-one empty containers from the bottom of a stack of such containers.
  • a feed means in the form of a transfer table which is rotatable about a vertical axis, serves to transfer the empty individual containers from the de-stacker and into the individual shells 14.
  • FIGS. 3 to 5 show a suitable de-stacking unit, and such unit includes a housing which is mounted for rotation about the horizontal axis indicated by 112 in FIG. 3.
  • the housing includes a top plate section 114 which is provided with a boss 116 surrounding an aperture 118.
  • Equiangularly spaced around the aperture 118 are three support rods 120 which serve to hold a stack of the containers to be accepted by the unit shown in FIGS. 1 and 2.
  • the container stack is indicated at 122 in FIG. 4 in position in the de-stacker unit.
  • the rotary transfer table passes under the aperture 118 and the bottom of stack 122, and this transfer table is provided at equal intervals on the pitch circle indicated by 124 in FIG. 3 with a plurality of individual container receiving cavities the arrangement being that the stack of containers is placed between the guides 120 and the containers pass through the aperture 118 as they are de-nested individually from the bottom of the stack and the individual containers are positioned in the holders travelling on pitch circle 124.
  • Pitch circle 124 lies in a horizontal plane and has its center at the axis of rotation of the transfer table.
  • a spring loaded plunger 126 serving to hold the plate 110 in position by locating in a bore 128 in a stationary framework work 130 on which the plate 110 is mounted. Should it be desired to swing the plate 110 and the components carried thereby clear of the table having the cavities on pitch circle 124, then plunger 126 is pulled manually as indicated by arrow 132 in FIG. 4 thereby releasing same from the bore 128 and the plate 110 and the components carried thereby can be swung about axis 112 and clear of the transfer table. This is useful in cases where it may be desired to clear a blockage of containers 122.
  • a gear 134 rotates another gear 136 with which it meshes and gear 136 is in'turn drivingly connected to a rotary damper unit 138 to retard 'the acceleration of the plate 110 between the in use and out ofuse positions.
  • the plate 110 includes means for imparting to'the bottom container in the stack an initial separation from V the remainder of the stack and also means whereby jets of air can blow the partially separated container away 'from'the remainder of the stack and :quickly into the '122.
  • the rotors 140 aregdrivingly connected to vertical shafts 146' and gears 148 connected to the top ends of shafts 146 are drivingly interconnected by means of an endless band of toothed timing belt 150 to ensure'that the rotors 140 rotate at exactly the same speed and in relation to their helical grooves 144 are exactly in phase.
  • One of the shafts 146 carries on a portion which extends above the gear l48,,a further gear 152 which meshes with a drive pinion 154 which is carried by a vertical shaft 156 which extends through and'isrotatably mounted on the plate..1'10.*
