Referring to' the drawings, a carrier'l having t" tw'oiopposed radially projecting arms 2 isrot'atably mounted 'on' a fixed spindle Earranged above andparallelto: the catcher band 4of a cigarette making: machine. The axis. of the spindle is transverse to the direction of'movement of the band.
The spindle 3- and thecarrier'arrns 2 are hollow" and the spindle is connected to a suction pump inot shown) whereby air maybe drawn through apertures in the arms.
nozzle: adapted" to.- move above'and near thear saidmozzle having 8;. suction aperture so disposed i 5; that at the momentuwhenan article is taken up A rotary valve is provided which may; for example, comprise.
The arms are substantially rectangular incross-section and each arm has a wall 6 at the end remote from the spindle, which closes the end of the arm. I a
Thus an arm comprises parallel front and back from the lowest position suction may be cut off and the cigarette is then simply supported by the arm which then acts as a mechanical conveyer. At any point after the cut off takes place the cigarette may be removed from the arm, for example, by a movable fork which engages the ends ofthe cigarette which protrude beyond the H width of the arm.
walls and two parallel side walls at right angles 7 to the first pair,
An aperture 1 is made in each arm in one of the side walls and'near to the end of the arm so that in fact the end wall 6 constitutes one boundary, of the aperture. The aperture is rectangular in shape, its depth (i. e. distance measured towards the spindle) being a little less than the diameter of a cigarette, while its length (i. e. as measured in a direction parallel to the spindle) is, say, two-thirds of the length of a cigarette, see Figure 3. 'An abutment 9 may be provided to regulate the area of the aperture. This abutment may be adjustable as shown in Figure 3, where it is attached to the arm 2 by screws passing through slots 29. a
The apertures in the arms are spaced apart by 18 0f and further, the apertures are located in those side walls of the arms which are leading when the device rotates inthe direction of the arrow. If desired, the apertures may comprise small rectangular tubes projecting from said side walls as'shown in Figure '4. The outer edge of each aperture, in the other views, (i. e. the edge adjoining the end wall of an arm) has'a small projecting lip 8 which constitutes an extension of such edge. 9
As viewed in a direction parallel to the plane of the aperture the lip is substantially triangular in shape-see Figure 3, with its apex in the middle'of the aperture length. The apex may extend say beyond the aperture plane and the angular sides extend from the apex to the aperture plane at points near to the side edges of the aperture.
A suitable arrangement is shown in Figures 1 and 2, where a conveyer I I consisting of a pair of discsl2 spaced apart on a common rotatable spindle i3 is used to deliver the cigarettes to a pan M of a weighing device l5. The pan comprises a pair of flexible prongs it between which the'discs l2 are movable. and the parts are so arranged that a cigarette I?) carried by the discs ashereafter described may be delivered into the.
pan so that the back of the pan and the flexible prongs respectively contact with the periphery of the cigarette ID as shown in Figure 1. The discs are each provided with two prongs I1 and 18 on their edges, the prongs being spaced apart on the circumference of the disc as shown, and
- the prong i3 is shorter than the other prong I1.
Preferably the lip is curved as I away from the spindle than does the base of the triangular extension.
In the operation of the device the carrier is rotated so that an arm passing near to the travelling band is moving in the same direction as the band but at a lower speed.
Thus the cigarettes ion the band, which travels in the direction of the arrow, Figure 1, move beneath the arm and overtake the same. When a cigarette has passed a little beyond the arm and the end of the latter is at its lowest position (i; e. when the plane of the aperture is substantially normal to the band 4) such cigarette will come'underthe influence of the suction through the aperture and will rise and cling to the aper The two discs are fixed on the spindle 13 with theirprongs in alignment. The shorter pair of prongs l8 constitute conveying means whereby a cigarette delivered on to the edges of the discs by a suction nozzle may be retained in position thereon and moved around with the discs.
In operation the discs are rotated in timed relationship with the carrier l and a cigarette is fed on to the short prongs at each half revolution of said carrier.
A cigarette is transferred from a nozzle to the conveyer H at about the'position indicated by the reference A, Figure 1. At this position the prongs 13 of the conveyer which are moving at a slightly greater speed than the nozzle overtake the latter and lift the cigarette therefrom. The suction is out off by the aforementioned valve at or before this time. A pair of guides l9 shield the conveyer and prevent accidental displacement of a cigarette carried by the prongs.
The longer pair of prongs I? are leading as the discs [2 rotate and consequently as they move between the prongsv it of the scale pan they positively move any cigarette in such pan out of the bottom thereof, the prongsof the pan bending under the pressure exerted by the prongs l1 away from the back of the pan to allow this. While this movement is taking place the short pair of prongs deliver another cigarette, as described below, into'the pan where it is retained for weighing by the flexible prongs I 6 which move inwards again as soon as the first cigarette has passed out of the bottom of the pan.
In order to facilitate the entry of the cigarette into the pan a pair of fixed guides 20 are arranged near the delivery position. The cigarette eventually engages the guides and rolls down them or is urged to do so by the prongs l8. As the pan may be moving during this operation, further guides 2| in the form of upstanding projections 'on the back of the pan are provided to control the path of the cigarette. The guides i251 continue downwards and-in conjunction with a pivoted flap 22 form a passage to guide weighed and discharged cigarettes back to the catcher band 4. 'The conveyer l I and carrier l are driven in timed relationship by a gear 23 on the spindle 13 which meshes with-a gearLZA on :the carrier I. The spindle i3 is driven from the weighing apparatus, which is a mechanically operated device.
Although the invention has been described with reference ;to the removal of cigarettes from atravelling band, it will beclearthat it isadaptable to other arrangements, for instance, the cigarettes might be conveyed on a fluted wheel as is common :in .the art.
What I claim as my invention and desireto secure .by Letters. Patent is:
1. A device for removing singlearticles from a moving row in which the articles lie transversely to their direction of movement, comprising a conveyer for a row of articles, a nozzle having a suction aperture, said nozzle :being mounted for movement in a fixed path located above said conveyer and at a distance therefrom which is slightly greater than the height of a row of articles on the conveyer, and means to move the nozzle in a manner such that when an article is removed thereby from the conveyer the nozzle has a component of movement in the direction a of movement of the conveyer and the suction aperture faces substantially in the direction of movement of the conveyer,
