Definitions

  • the transport of the tobacco to the collecting point from which the portion is conducted into the spreader is efiected in such manner that the portion accumulates before the predetermined number of revolutions of the spreader driving shaft, the transport being then automatically interrupted.
  • the invention also relates to an apparatus suitable for use with the new method.
  • the tobacco is fed to a weighing device, the tobacco pan or the like of which describes a movement, restricted by a stop, when the prescribed weight is reached, and thus shuts off the further supply of tobacco, without emptying the pan, whilst, when the specified number of revolutions is completed, the pan is emptied into the spreader owing to the fact that the driving mechanism of the latter causes the stop to be put out of action.
  • the weighing apparatus consists of a horizontal, or approximately horizontal, sieve, which is interposed in a pneumatic conveyer pipe and arranged as a flap, with an eccentric hinge and provided with a counterweight, so that, when the requisite amount of tobacco has been supplied, the flap describes a swinging movement, limited by a stop, the flap being connected with the continuation of the pneumatic conveyer in such manner that such continuation is shut ofi from the suction device, (exhauster or the like) when the flap is displaced.
  • the stop for the first movement of the flap (without emptying) is carried by a control rod mechanism which is connected with the drive of the tobacco spreader and slidablyengages the flap in such a way that, after describing an idle stroke, the rod mechanism sets the flap in the open position in which the tobacco passes to the spreader, through a 0 feed pipe if necessary.
  • the pneumatic conveyer device is preferably designed in such a way that two tubes-a suction tube and compressed air tube-lead from the exhauster or the like, both of them opening into a guide surface disposed concentrically in relation to the hinge of the flap.
  • the tube attached to the flap slides, by means of its correspondingly shaped end, on the guide surface in such a way that said tube is connected to the suction tube while the weighing apparatus is being charged, but is shut off by the guide surface during the preliminary oblique position of the flap, and finally is connected to the compressed-air tube when the flap is fully open.
  • the swing of the weighing flap in the sense of cutting off the suction air closes an electric contact which completes a circuit the 1 effect of which is to close a. flap disposed in front of the mouth of the charging hopper, and at the same time to actuate a signal (such as an electric lamp near the charging hopper.
  • Fig. 1 shows the position of the device during the transportation of the tobacco
  • Fig. 2 shows the position when the requisite amount of tobacco has accumulated on the weighing apparatus and everything is ready for delivering the tobacco to the spreader
  • Fig. 3 shows the position of the weighing apparatus in the course of delivery on to the spreader
  • Fig. 4 shows the hopper serving to feed the conveyer apparatus.
  • the cut tobacco is drawn by the suction stream of the blower b through a pipe a, which is connected either with a tobacco shredding machine or a hopper into which the tobacco is poured.
  • a receptacle 0 which is mounted in the suction pipe 100 a, a is provided with a sieve e or the like which swings on a hinge d.
  • the tobacco conveyed by the suction current settles on the sieve, until it balances a counterweight l' adjustably' mounted on a balance lever Z.
  • the sieve now swings until 105 the attached levere' bears against a stop, which is formed by the upper end of a slot 1 provided in a link h and is engaged by a pin on the lever e.
  • the link It is pivoted at w on a two-armed lever u pivotally mounted at 12, its other end, which is 110 provided with a roller it, being controlled by a cam t mounted on a shaft s of the tobacco spreader.
  • the shaft s rotates at the same speed as the spreading roller :2 which acts in the receptacle y of the spreader. In this manner, at each rotation of the roller 1:, the roller 1!, of the lever it enters the cavity in the cam t.
  • Attached to the sieve e is a pipe section It the end of which slides over a concentric surface It into which the suction pipe 11. and the delivery pipe a of the blower terminate.
  • the mouths of these pipes are so arranged that the pipe k faces the suction pipe a when the weighing apparatus is in the neutral position (Fig. 1), so that tobacco is drawn from the pipe a by the blower b.
  • the mouth of the pipe moves away from the mouth of the suction pipe (1. thus interrupting the suction current and stopping the conveyance of the tobacco.
  • a dust separator of known type is preferably disposed in the suction pipe 0. or delivery pipe 11
  • the weighing apparatus carries an electric contact 1 which is closed by contact with a contact piece 2 in the position shown in Fig. 2.
  • the circuit completed by these contacts actuates a flap 0, which closes the bottom of the feed hopper 0
  • the circuit can also actuate a signal (glow lamp 1;) on the feed hopper, which notifies the operative that no tobacco should be put in.
  • Another signal may also be provided, which indicates, by means of two electric contacts a in the receptacle of the spreader, whether too much, or too little, tobacco is present in the receptacle.
  • the tobacco may also be supplied, from a feed table, to the conveyors of a plurality of spreaders, in which case a separate hopper a and special pipe can be provided for each machine, so that a different kind of tobacco can be treated in each cigarette machine.
  • all of the tobacco can be placed in one feed hopper and passed to a main pipe from which different branches lead to the receptacles c.
  • the transfer of the flow of tobacco from the main pipe into the branches can be effected by manipulating flaps, which, like the flaps o, are electrically controlled by contacts provided on the sieves e.
  • the device serving to carry out the new method can also be applied to other uses where it is a question of weighing out definite amounts of material passing through a pneumatic conveyer, and preparing said amounts for delivery to a point of consumption.
  • a tobacco treating means having a re-. volving element, and a tobacco delivering means, of an automatic device between said two means for controlling the quantity of tobacco to be delivered at a time to said treating means including means controlled from said element for causing the delivery of said quantity to said treating means so that after a predetermined number of revolutions thereof the quantity of the tobacco delivered will correspond to the quantity treated by said tobacco treating means during. said revolutions.
  • a pneumatic tobacco feeding apparatus the combination with a tobacco spreader having a revolving element, and suction controlled tobacco feeding conduit, of an automatic device between said spreader and conduit for controlling the quantity of tobacco to be delivered to said spreader at a time, said device including means for causing the interruption of the suction action in said conduit at the accumulation of a predetermined quantity of tobacco and means controlled from said revolving element of said tobacco spreader for causing said predetermined quantity of tobacco to be delivered into said spreader.
  • said tobacco accumulating support consists of a tubular body capable of communicating with the pneumatic conduit and having a perforated tobacco supporting surface.
  • said movable tobacco ac.- cumulating support consists of a tubular body having a perforated tobacco supporting surface and being capable in normal position of communicating with the pneumatic'feeding conduit
  • tubular body cooperating with means for interrupting said communication when a predetermined quantity of tobacco has accumulated on said support.
  • a pneumatic device having suction and compressed air pipes, a gravity actuated tobacco accumulating support having a tubular extension capable of communicating successively with said suction pipe and compressed air pipe and means intervening between said pipes to shut off communication with either one of said pipes while said support is in intermediate position.
  • a tobacco feeding apparatus the combination with a tobacco spreader, of a tobacco col-' lector connected to said spreader, a tobacco accumulating flap pivotally mounted in said collector and adapted to normally close said collector against said spreader and on the accumulation of a predetermined quantity of tobacco thereon to swing into open position and discharge said tobacco into said spreader.
  • a counterbalanced tobacco accumulating support in said collector adapted to normally close said collector against said spreader and means controlled from said revolving element and operatively connected to said support so as to swing the same into open position after a predetermined quantity oftobacco has accumulated on said support.
  • said means controlled from said revolving element consists of a double armed lever having a slotted link and means connected to said tobacco accumulating support and engaging the slot in said link, so that said support will be allowed to swing into open position only after a predetermined quantity of tobacco accumulated thereon has overcome the counter-balance thereof.
