Definitions

  • a conveyor system for conveying articles, such as cigarettes, which are filled into containers at a filling position and are emptied from the containers at an unloading position comprising a conveyor carrying members having means to automatically pick up a full container and deposit an empty container as a member travels past the filling position and to automatically deposit a full container and pick up an empty container as the member travels past the unloading position.
  • the invention further provides a cigarette-making and packing system comprising a cigarette-making machine, a tray-filling machine to fill trays with cigarettes made on the cigarette-making machine, a packing machine to unload and pack cigarettes from the filled trays, using such a conveyor system to convey full trays of cigarettes from the tray-filling machine to the packing machine and empty trays from the packing machine to the tray-filling machine.

  • FIGURE 2 is a diagrammatic plan view of an overhead conveying system
  • FIGURE 3 is a side view of part of the system of FIGURE 2,
  • FIGURE 3A is a detail of the hangar swivel joint
  • FIGURE 4 is a detail of part of FIGURE 3,
  • FIGURE 5 is a further detail of part of the system of FIGURE 2,
  • FIGURE 6 is an alternative mechanism to that of FIGURE 5,
  • FIGURE 7 is a modification of the system of FIG- URE 2.
  • a cigarette container or tray 1 containing cigarettes C is held in a holder shown generally as 2.
  • the holder 2 comprises two side strips 3 and 4 joined at their lower ends by a base plate 5 and at their upper ends by a cross bar 6.
  • the bottom of the tray 1 is held between two pivot pins 7 and 8, being swivelable about the axis of the pins.
  • the pins 7 and 8 project from plates 9, of which only one can be seen, fixed to the base plate 5.
  • Fixed to the centre of the cross bar 6 is an eye 10 into which can be inserted a horizontal portion 11 of a supporting member 12 (see also FIGURE 3). When suspended from the supporting member 12 the tray in the holder is tilted as shown.
  • FIGURE 2 six tray loading stations 13, 14, 15, 16, 17 and 1-8 which in this case are tray filling machines attached to cigarette making machines, feed trays to three off-loading stations 19, 20 and 21, which in this case are packing machines which unload and pack cigarettes from filled trays.
  • the trays are held in the holders 2 (see FIGURES 1 and 3) which are suspended from an overhead continuously movable chain conveyor 22 (shown in FIGURE 3 as a line).
  • Each tray loading station 13, 14, 15, 16, 17 and 18 supplies filled trays in position 23 and has empty trays delivered to position 24 (shown only in the tray loading stations 13, 16 and 17).
  • the packing machines 19, 20 and 21 are provided with full tray olfloading positions 25 while positions 26 accommodate emptied trays ready for being picked up by the conveyor 22.
  • the direction of movement of the conveyor 22 is anticlockwise as seen when looking at FIGURE 2.
  • each packing machine and tray loading station are detector mechanisms 27, 37, 47, 57, 67, 77, 87, 97 and 107.
  • a guide 28 At a lower level than the run of the conveyor 22 is a guide 28 (see also FIGURES 3 and 5) which holds the suspended holders 2 in a steady position.
  • tray filling machines sometimes referred to herein as tray fillers
  • packing machines 19 20 and 21 part of the guide 28 can be switched to either one of two positions by the appropriate detector mechanisms 27, 37, 47, 57, 67, 77 87, 97 and 107, i.e. it can continue straight on as shown in full lines in FIGURE 2 or it can branch as shown in chain lines 29.
  • the two positions can be clearly see in FIGURE 5 as can the effect the guide (at position 28 or 29) has on the holder 2 and its cigarette tray 1.
  • each may comprise a strain gauge 30A and pick-off 30B (shown diagrammatically in FIGURE 3) incorporated in the track of the overhead conveyor 22 so that a signal can be generated whose magnitude depends on the weight of the tray passing below.
  • Each pick-off 30B may include an amplifier to provide a suitable output signal to a course-determining device 87A which directs the hanger 30 along the appropriate path, as will be further explained. In this way the passage of full and empty trays can be clearly distinguished.
  • FIGURE 3 is a view indicated by arrow III-III in FIGURE 2.
  • From the overhead conveyor 22 (shown in FIGURE 3 as a line) depend hangers 30. At the lower end of each hanger 30 is the supporting member 12 with its horizontal portion 11.
  • the hanger 30 is pivotable about its vertical axis, 31 being a swivel joint.
  • the guide 28 for most of its run, i.e. that part excluding the portion opposite to the tray filling machines and the packing machines, is doubled, as can be seen in FIGURE 4.
  • the effect is that of a single guide having a vertical slot through its centre.
  • the hanger 30 passes through this vertical slot.
  • the hanger 30, whose section is rectangular, is provided with a 180 twist 32.
  • FIGURE 2 which is but one of many possibilities, there are six tray fillers feeding three packing machines. Even in this single layout, the combinations available are considerable.
  • the packing machine 19 is to be fed from the three tray fillers 13, 14 and 15, the packing machine 20 from the two tray fillers 16 and 17 and the packing machine 21 from the tray filler 18.
  • the function of the detector mechanisms 27, etc. as well as preventing empty and full tray being fed to packing machines and tray fillers respectively is to ensure that the correct full trays reach the 'correct packing machine destination and that empty trays are returned either to the tray filler from which they originated or to a tray filler feeding the same packing machine.
  • a coded disc 38 (see FIGURE 3) to the back of each tray 1, i.e. on the opposite face to the one revealed in FIGURE 1.
  • the code consists of black bars pointed vertically on a white surface.
  • trays used for tray fillers 13, 14 and 15 might have on vertical bar, trays used for tray fillers 16 and 17 two vertical bars, and trays used between the tray filler 18 and the packing machine 21 three vertical bars.
  • the mechanism fuctions as follows.
  • the detector mechanisms 27, 37 and 47 are set to operate the part of the guide 28 which can be moved to position 29 appropriate to their respective tray fillers 13, 14 and 15 so that only empty trays bearing discs with one vertical black bar are shunted on to to a table 33 (see FIGURE 5) of a tray filler having space for an empty tray.
  • these detector mechanisms are only activated when their own respective tray filler is ready to have an empty tray delivered and, therefore, a full tray removed, while the part of guide 28 which is movable t position 29 can o y i s f e act a d y .a
  • tray bearing the correct coded disc passing an activated detector mechanism Any convenient form of detector mechanism suitable for distinguishing between the different disc codings may be used. If the tray filler 13 is in a condition to receive an empty tray, i.e. if it has a full tray in the position 23, the detector mechanism 27 is activated. Any empty trays having discs with two or three vertical bars are allowed to pass but the first empty tray with a single barred disc will be accepted since the detector mechanism 27 causes the part of guide 28 to move to position 29 to swing the empty tray 1 into the position shown in chain lines in FIGURE 5. A stop on the table 33 detains the tray 1 and its holder 2 so that the trailing end of the horizontal portion 11 of the support member 12 moves out of the eye 10 leaving empty tray and holder behind.
  • the full tray has a disc with one vertical bar on its back i.e. on the side towards the detector mechanisms 37 and 47 etc. and, therefore, passes on past all the other tray fillers without being deflected.
  • This empty tray will therefore pass by the packing machines 20 and 21 because it does not carry a correctly coded disc and also because it is empty.
  • the guide 28 rises from its lower position to its higher one and in so doing turns the supporting member through 180.
  • the empty tray is thus on the trailing end of the horizontal portion 11 while the back of the tray with its coded disc is directed inwards and is thus in the correct position for activating whichever of the three detector mechanisms 27, 37 or 47 is ready.
  • the empty tray is again turned through 180 so as to be ready to activate the movable part of guide 28- appropriate to the ay filler 18 when it pa s he etector mechanism 77 it by then there is a full tray ready to be picked up.
  • a full tray will be recirculated if its correct packing machine destination has no requirement for a full tray.
  • FIGURE 6 there is shown an alternative embodiment.
  • the trays being swung through an are by the part of guide 28 which can move to position 29 the table 33 of the packing machine or tray filler is extended as shown at 40.
  • a slidable plate 41 is actuated either to be in a position to intercept and receive a correctly coded tray or to be out of position to allow the incorrectly coded trays to pass by. Once a tray is located on the plate 41, the latter is moved inwards so as to deliver the tray to its required position.
  • FIGURE 7 shows a modification.
  • the hanger 30 has pivoted to its lower end an extension 42 which is again pivoted to a member 43 having the supporting member 12 rigidly fixed to its lower end.
  • a lug 44 is fixed to the member 43.
  • a cable 45 passes around a pulley 46 fixed to the lower end of the hanger 30 and is anchored to the lug 44.
  • the free end of the cable 45 is actuatable by a cam, which is not shown, to raise the supporting member 12 to the position shown in chain lines in FIGURE 7.
  • a tray can be lowered into position as it is being deposited or can be raised as it is being picked up, in both cases thereby reducing the possibility of shaking or juddering of the tray.
  • a conveyor system for conveying cigarettes which are filled into trays at a filling position and emptied from the trays at an unloading position comprising an endless overhead conveyor, members depending from the conveyor and having means to automatically pick up and deposit trays at said positions and arranged to carry trays between said positions, first detector means associated with said filling position, activated responsively to the presence of a full tray at said filling position, and operative to detect the loaded condition of a tray approaching said filling position, means operative responsively to said first detector means to guide an empty tray to, for deposit at, said filling position when a full tray is present at said filling position, and to guide full trays and, when a full tray is not present at said filling position, empty trays so that they by-pass said filling position, second detector means associated with said unloading position, activated responsively to the presence of an empty tray at said unloading position, and operative to detect the loaded condition of a tray approaching said filling position, and means operative responsively to said second detector means to guide a full
