England Application September 14, 1951, Serial N 0. 246,695
Claims priority, application Great Britain September 23, 1950 Claims.
The invention relates to apparatus for use in packing loose materials, particularly fibrous materials.
In the production of woolen yarns, for instance, it is customary to make blends of the various colours of loose WO01 required to produce yarns of the desired colour or shade.
The mixed or blended wools are then packed into sheets or containers until required for use, and it is with the packing or consolidation of the material into the sheets or containers with which the invention is primarily concerned, though the apparatus constituting the invention will or may [find useful application in other directions for packing or consolidating loose fibrous or other material into containers.
The invention will be described With reference to the accompanying sheet of drawings, in which Fig. 1 is a side elevation partly in cross-section; and
Fig. 2 is a plan view, partly in cross-section of packing apparatus embodying the invention;
Fig. 3 is an elevation of means for enabling material fed to the machine to be diverted to any other point of delivery either at will or automatically as will be described later.
Fig. 4 shows in an open position doors which are shown in a closed position in Fig. 2, Fig. 4 being a fragmentary partly sectional view of part of the apparatus of Fig. 2. Referring to the drawings, material to be packed is conveyed by a suitably impelled air current along a feed conduit 17 to the upper end of an open-topped hopper or receiving chamber c having suitably perforated Walls. The lower end of the hopper 0 opens into the path of a reciprocating ram d, shown as being operated by a cable e passed about a winch ,f driven by a reversing electric motor g.
Loose fibrous material delivered into the hopper 0 falls into the path of movement of the ram d by which it is forced into a packing chamber 72. at the entrance to which there are provided two pivoted doors 2', i, loaded by respective springs z',-i'
As will be seen from Fig. 2, the doors 2', i, are in the form of quarter circles the reason for this being to prevent trapping of material behind them when being opened, as would occur if the doors were in the form of flaps or plates. The springs z", 2', have merely the function of closing the doors as the ram d recedes. Fig. 4 shows the doors 2', i in their open position, to which they are moved when the ram d has moved into the tubular portion h.
Suitably mounted on the ram d are four ramps 1d, d d and d The ramps d and d are arranged to operate a two-way switch d controlling, through the motor g, what may be referred to as the short-stroke reciprocation of the ram d, the length of which is indicated in Fig. 1 by the disposition of the ramp d in relation to the ramp at.
At the delivery end of the packing chamber it there are provided two pivoted doors 7', 5i, loaded by respective springs a", the action of which is adjustable.
The loading imposed on the doors a, determines, as will be understood, the amount of compression exerted on the material forced into the packing chamber h by the ram d.
When the compression of material in the packing chamber reaches the pro-determined value it causes the doors 7', to be opened and at a determined point in the opening movement of the doors a switch is closed against the action of a spring. The closing of this switch is is arranged to change over from the switch d to a switch m operable by the ramps d and d on the ram d, the ramp 01 being so located in relation to the ramp d as shown in Fig. 1, that the ram id is now given a long stroke of reciprocation, such that the compressed mass of material in the packing chamber h is ejected past the doors 7, a.
Before each compressing operation commences, the open end of a tubular bag or container n is passed over the discharge end of the packing chamber It. When the compressed mass of mate rial in the packing chamber is discharged by the long-stroke movement of the ram d, it enters and carries with it the bag n which thus becomes filled, and is thereby pushed off the delivery end of the packing chamber. As the filled bag moves away from the packing chamber it is deposited upon a wheel-ed trolley p positioned beneath it, the forward end of such trolley having an upwardly projecting part 20, the abutment against which of the end of the forwardly moving bag it causes the trolley to travel forwardly along with the bag and thus to support the full length of the bag as it passes oir" the packing chamber.
An adjustable stop, not shown, is provided to arrest the movement of the trolley go away from the packing chamber a predetermined time before the ram (1 completes its ejecting stroke, so that the portion of material near the mouth of the bag n receives what may be termed a final compressing action to cause it to move fully into the open end of the bag n.
As the ram 1d arrives at the forward end of its long-stroke or ejecting movement, the ramp d opens the switch m. This interrupts the electric circuit and operates a relay, not shown, to change over the "ram movement from long stroke back to short stroke.
When the loaded bag has been carried clear of the packing chamber and the ram has moved sufiiciently far in its movement of withdrawal the springs acting on the doors 4,6105% the said tacts-either member r -or member 1" tocut off the current to the motors and thereby prevent the-occurrence of an accident.
.Inorder to obvlatethepossibility of damage or blocking of-the feed conduit 1) due to material piling up in'thehopper c, there may be provided in the iowerpart of the hopper a roller s driven irictionally through a centrifugal clutch s from an electric motors? This roller controls a switch s which, when the rotation of the roller 8 is arrested by accumulation of material in the hopper, is adapted to reverse'the direction of rotation of tin-electric motor t (Fig. 3). This motor is connectedby'belt or chain. gearing t to a rotatable disc This disc carries a pin a which is adapted, according to the-direction of its rotation to engage either one or the other of two fingers u and dependingirorn a horizontally slidable bar 1L This barisconnected by flexible connectorsu and a to acentrally pivoted lever 11 carrying a divertingplate adapted to control the entrance to a relief passage- '0 Solong as the roller s-is free to rotate, the bar tfiiscausedto occupy-a positionin'which the plate 2) closes the relief passage o ,-"out if the rotation of the roller s is arrested the switch 3 causes the direction of rotation of the motort to be reversed, with the result .thatthe bar 2& is moved longitudinally in the direetion of the arrow '3 in Fig. 3, causing the lever 22 to be rocked insadirection to swing the plate over from the position in which-it closes the-relief passage "0 tothat in whichit opens up the entranceto. such passage and closes the entrance to the feed conduit b. The material approaching through the supply conduit a .is thus diverted from the feed conduit 12 into the relief passageifi, through'which it is conveyed to any desired delivery point.
Above the roller 3 there is provided in the hopper 0 a deflector w by which material entering the hopper from the feed conduit is prevented'from falling on to the roller s.
'Atthe lower end of the hopper c, above-the path ofreciproeation of the ram d, there is provided a freely-pivoted lever y which rises and falls as the ram reciprocates and the function of which is to prevent the material packing or filling the lower end of the hopper above the ram.
The switch 8 may be arranged, in additionto actuating the diverting plate a, to operate an electrically-operated valvecontrolling a supply of oil tothe materialbeing dealt with, and tocut off'such supply duringdiversion of the material through the relief passage 0 In connection with the switch It there may be 4 provided a push-button control to enable the contents of the packing chamber to be discharged at any time independently of the automatic opening or" the doors 'y'yy'jby the action of'tthe compressed material in the packingchamber' h.
It will be noted that by varying the action of the springs controlling the opening of the doors -i,.-y',theamount-of compression applied to the 'mat-erialbefore entering the bag "It can be regulated as desired.
Provision will or may be made to give audible and/ortvisual' signals'prior to discharge of material into orirom the packing chamber h.
