  • This invention is concerned with methods and apparatus for receiving successive batches of cigarettes or other rodlike articles lying parallel to one another and side by side, and for feeding the articles transversely to their lengths.
  • Apparatus comprises a hopper having sidewalls which are parallel to the articles and extend in the direction of feed of the articles through the hopper, and a pressure member arranged to extend between sidewalls of the hopper and to move through the hopper, in the direction of the sidewalls, so as to apply continuous pressure to the articles in the hopper while being constrained against tilting during movement through the hopper.
  • This invention is particularly concerned with the case of a hopper with vertical sidewalls, and where the stream of articles is moved downwards through the hopper.
  • the pressure member which is conveniently in the form of a straight pressure plate, preferably applies pressure to the articles by moving downwards through the hopper under gravity.
  • the pressure member according to this invention is a useful means of maintaining the upper surface of the articles in the hopper (as an example in the preferred case of a downward feed) substantially level so as to be parallel to the bottom surface of a subsequent batch of articles.
  • This invention is particularly concerned with arrangements in which the articles are fed froma vertical hopper horizontally past one sidewall of the hopper, for example on a band conveyor.
  • the level of the-articles in the hopper tends to rise in the direction of the sidewall past which the articles are fed, so that the apex of the articles remaining in the hopper may have to be removed to make room for the next batch of articles; that is, unless a considerable vertical clearance is allowed, which is undesirable as it can, for-example, result in the articles becoming disorientated as they drop onto the remains of the previous batch.
  • Each batch of articles is preferably carried to a fixed hopper part in a tray which remains in position while the articles are being fed from the hopper, except for the removal of a bottom wall, and has sidewalls which function as vertical extensions of the sidewalls of the fixed hopper part.
  • An apparatus according to this invention can be arranged to supply a fast well-controlled stream of cigarettes to a highspeed packing machine.
  • FIG. 1 is an elevation (partly sectional) of the apparatus, viewed endwise of the cigarettes, showing a tray full of cigarettes;
  • FIG. 2 is similar to FIG. I but shows the tray partly emptied
  • FIG. 3 is a fragmentary section on-the line lll-lll in FIG. 2.
  • the apparatus comprises a fixed framework I which is arranged to receive in its lower part a tray having sidewalls 2, and to support in its upper part a raising and lowering mechanism for a pressure plate 3 which is used to control the movement of cigarettes out of the tray and which is movable up and down within the tray and has the same shape as the cross section of the tray-(see FIG. 3).
  • a fixed framework I which is arranged to receive in its lower part a tray having sidewalls 2, and to support in its upper part a raising and lowering mechanism for a pressure plate 3 which is used to control the movement of cigarettes out of the tray and which is movable up and down within the tray and has the same shape as the cross section of the tray-(see FIG. 3).
  • tray is open at the top and has a backwall 2a' and an open front.
  • tray When the tray is in the hopper, its open front lies against a transparent wall'(not shown in FIGS. 1 and 2) which is fixed to the framework 1.
  • the tray has a bottom wall 4 which passesthrough a slot in one of the sidewalls 2 and is horizontally slidable out of the tray to enable cigarettes to be removed downwards from the tray.
  • the tray is supported to rest upon a ledge '5 which surrounds the inlet to a fixed hopper part 6 which is positioned directly beneath the tray and has sidewalls 6A and 6B.
  • a flexible guide 11 controls the egress of the cigarettes from the hopper.
  • the conveyor 7 is run at a slower speed than the conveyor 8 and is positioned at a slightly higher level, the gap-being bridged by a bridge plate 12.
  • the speed ratio of the bands may, for example, be approximately 2.7: l.
  • the mechanism for raising and lowering the pressure plate 3 includes a pair of vertical guides 13 which carry the plate 3 across their lower ends and run through guide holes in the framework 1; the guides keep the plate 3 horizontal.
  • a cross piece 14 is secured between the guides 13 and is formed with a central aperture ISthrough which an operating rod 17 of a vertically acting jack 16 extends.
  • the jack is mounted on the upper part of the framework 1, and its rod 17 is formed at its lower end with a boss 18 which is too large to pass through the aperture 15, so that the pressure plate 3 can be raised by retracting the jack16.
  • a switch 19 is positioned on a crossbar 20 of the framework 1 and is operated by downward movement of the crosspiece 14 when the pressure plate 3 reaches the bottom of the tray.
  • the apparatus is operated to function in the following manner.
  • Each tray is moved into position in the direction of the cigarettes until it reaches the wall 2b.
  • the jack 16 holds the pressure plate 3 at the top of its travel so that the tray can be moved in beneath it.
  • the bottom wall 4 of the tray is withdrawn, allowing cigarettes to move under gravity out of the tray and into the hopper part 6 where they rest on cigarettes already in the hopper.
  • the jack l6- is extended to its maximum, thereby transferring the weight of the pressure plate'3 and its guides 13 to the cigarettes.
  • the cigarettes are thus subject to constraint to have a flat upper surface which is horizontal as the pressure plate 3 is maintained in a horizontal position by the guides 13.
  • the conveyors 7 and 8 run continuously to remove a continuous stream of cigarettes 9 from the hopper, and so the level of the cigarettes in the tray 2 drops steadily, as is shown in FIG. 2.
  • the crosspiece 14 operates the switch 19 and causes the jack 16 to be retracted to raise the pressure plate 3 to its uppermost position (FIG. I).
  • the bottom 4 of the tray is then pushed back into position and the tray 2 is removed by being moved initially in the direction from which it was delivered, and another full tray is brought into position for the purpose to be repeated.
  • the side and front walls of the fixed hopper part 6 are extended upwards to the height of the crosspiece 20;
  • the trays are then positioned in turn alongside (i.e. behind) the hopper with the bottom wall 4 of the tray positioned at the level of the ledges 5.
  • the backwalls 2a of the trays are omitted (or made removable) to enable the cigarette contents of each tray in turn to be pushed in the direction of the cigarettes 'through' the open front of the tray into the upper part 'of the hopper.
  • the bottomwalls4 of the'trays would in this case be fixed to the sidewalls 2, and each tray may also include a fixed top wall.
  • the apparatus comprising a hopper having substantially vertical sidewalls which are parallel to the articles and extend in the direction of feed of the articles in the hopper, the upper part of the hopper formed successively by each of a number of trays including vertical sidewalls and delivering articles to the hopper, the vertical sidewalls of said hopper cooperating with the vertical sidewalls of each tray in turn to form a hopper through which the articles move in a downward direction, a pressure member arranged to extend between the sidewalls of the hopper and to move downwards through the hopper under gravity so as to apply continuous pressure to the articles in the hopper, means to prevent the pressure member from tilting during movement through the hopper, and means to feed the articles horizontally from the hopper, past one of the sidewalls, said feed means comprisinga first
  • Apparatus for receiving successive batches of cigarettes or similar cylindrical rodlike articles lying parallel and side by side in trays which are rectangular in'shape and have dimensions in each direction such as to accommodate a large number of cigarette dismeters comprising means for delivering successive trays to a discharge position, means for initially supporting the batch of cigarettes from each new tray at a position above the upper surface of the cigarettes remaining from the'previous tray, means for dropping the contents of each new tray on to the upper surface of the cigarettes remaining from the previous tray, means for feeding the contents of the new tray downwards whereby the upper surface of the cigarettes in the tray tends to depart progressively from a flat, level contour as a result of relative rolling of the cigarettes, a horizontal pressure member arranged to rest on the upper surface of each batch of cigarettes in turn and having a width measured transversely to the cigarettes such as to extend from one vertical sidewall of the tray to the other vertical sidewall, whereby the pressure member moves downwards through the tray while applying continuous pressure through gravity on the upper surface of the cigarettes in the tray and thus maintains the
  • the lifling means comprises a fluid-powered jack having an operating member which is movable vertically upwards to lift the pressure member and is movable downwards to release the pressure member and thus allow it to move downwards under gravity.
  • Apparatus according to claim 2 in which the cigarettes are fed horizontally from each tray on a conveyor band moving past and below one of the vertical sidewalls of the tray.
