8 Claims.

This invention relates to improvements in continuous-rod cigarette machines, more particularly to the cigarette-catching mechanism thereof. The main object of the invention is to separate the cigarettes without injuring them as they issue in single file from the cigarette machine cut-off, and then successively halt the cigarettes and transfer them on to an endless` collecting or delivery belt.

This object is achieved in the embodiment of the invention selected for illustration herein, by van endless suction belt driven at a greater linear speed than that of the cigarette rod and acting to accelerate the cigarettes to space them and then deliver them in front of a transfer which periodically pushes the separated cigarettes sidewise on to a delivery belt and into the space between the latter and a friction roller mounted above the belt and rotating at the same linear speed. The contact of the transfer with the sides of the cigarettes acts to slightly reduce the momentum imparted to the cigarettes by the separating suction belt, and the engagement of the friction roller therewith acts. to further retard and finally halt the endwise movement of the cigarettes as they pass sidewise under the same. With this and other objects not specifically mentioned in View the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawing which forms a part of this specification and in which like charn acters of reference indicate the same or like parts:

Fig. 1 is a plan view of the improved cigarette catching mechanism;

Fig. 2 is a side elevation of from line 2-2 of Fig. l;

, Fig. 3 is a sectional end elevation of the suction chamber and suction belt on line 3 3 of Fig. 2; and

Fig. 4 is a fragmentary plan view of the same.

Generally stated in the particular embodiment f of the invention herein illustrated the cigarettes are received endwise from a cigarette machine cutoff and suctionally gripped and advanced at a speed greater than that of the cigarette rod to establish spaces therebetween. In the best constructions contemplated the cigarettes, as they issue from the cigarette machine cutoff, are engaged by a traveling suction belt, which may be perforated or formed of air-permeable material and runs over a slot in a suction chamber, acting to suctionally grip and advance the cigathe same viewed rettes. The spaced cigarettes may be then pushed by a transfer of any suitable or desirable construction, While they are being forwarded by the suction belt, on to a traveling collecting belt whereon their endwise movement is retarded and halted by a rotating friction roller. This construction may be Widely varied for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the details illustrated and described, nor to the particular embodiment chosen as illustrative of the invention.

Referring to Figs. 1 to 3 of the drawing, the particular embodiment of the cigarette catching mechanism selected for illustration comprises a suction belt 5 running in the direction of and at a higher speed than the cigarette rod C; an orbitally moving pusher 6 periodically advancing to engage and displace a pair of cigarettes C', C"; an endless collecting belt I running at right angles to the direction of the cigarette rod; and a friction roll 8 rotating at the same linear speed as the collecting belt.

The suction belt 5 runs over an idler pulley 9 on a shaft Ill and is driven by a pulley II on a shaft I2 carrying a sprocket driven by a chain I3 from a sprocket on the shaft` I4 of a wheel I5 which drives the rod-forming tape I6 propelling the cigarette rod'C. The pulley II has a number of studs I1 which engage with holes I8 in one edge of the belt 5 to drive the latter without slipping. The belt 5 may also be provided with spaced groups of holes I9, Fig. 4, each group registering with one cigarette and all groups registering with a slot 20 in the top of a suction chamber 2| which has a duct connected to a suitable source of suction (not shown) and is provided with a projecting ledge 23.

The particular type of transfer selected for illustration herein comprises a pusher S having arms 24 which are connected to parallel cranks 25 on vertical crank shafts driven by spiral gears 25 from a shaft 21 driven by bevel gears 23 from a shaft 29 which carries a sprocket driven by a 45 chain 3D from a-sprocket on shaft I2. A sprocket 3l on shaft 2l drives a chain 32 running over a sprocket 33on a shaft 34 on which the driving pulley 35 of the collecting belt l is mounted. The shaft 3d, by means of intermeshng spur'gears 50 36, also drives a shaft 3I which carries the friction roll 8, which isv made of sponge rubber or other suitable material.

The cigarette rod C is propelled by the tape I6 into the bell-mouth 38 of the ledger tube 39 55 wherein the cigarette rod is cut into individual cigarettes by knives 4|) on a rotating carrier 4|, the same constituting a cigarette machine cutoff of well kno-Wn type. Thus, the cigarettes are severed from the rod C by each knife 40 successively at each half revolution of the carrier 4|. When the rod C is provided with spaced cork strips K, by a cork-tipping mechanism (not shown) acting to apply the strips to the cigarette paper before it enters the rod-forming mechanism, the cuts are successively made in the centers of these strips and half-way between them,

so that the cork tips of successive cigarettes` issuing from the tube 39 point in opposite directions. The pusher 6 then delivers them in pairs on to the conveyor belt 1 in two parallel rows C and C in each of which all the corp tips point in the same direction.

The knife carrier 4| is mounted on a shaft 42 arranged obliquely to the cigarette rod and driven by a belt 43 from a shaft 44 which, in turn, is driven from the tape-wheel shaft I4 by means of bevel gears 45. The shaft I4 thus imparts motion to all the working parts of mechanism, thereby insuring synchronism of their operation with the cigarette machine cutoff. It should be noted, however, that other types of cigarette machine cutoifs may be used instead.

As the cigarettes issue from the cigarette machine cutoff they register with successive groups of perforations I9 in the belt 5 and are suctionally retained thereon and accelerated to establish spaces therebetween and forwarded endwise in front of the pusher 5. Thereupon the latter pushes them sidewise individually, or in pairs as shown herein. This sidewise displacement of the cigarettes is begun while they are still being suctionally held on the belt 5, and they are pushed over the ledge 23 on to the belt 1. At this time the engagement of the friction roll 8 with the tops of the cigarettes being delivered to the belt 'l serves to retard and halt their endwise movement. Each group of perforations has the same length as a cigarette, and the ends of the latter register with ends of the perforated portion.

It is believed that the advantages of the present invention in avoiding injury to ends of the cigarettes by suctionally gripping them while spacing them should be explained. Since the cigarettes are retained on the suction belt by the suction applied to their bottoms, there is no tendency to crush their leading ends such as would arise when they enter between opposed traveling or relatively moving surfaces ooacting to accelerate and space the cigarettes. Furthermore, it is evident that the registration of the groups of holes in the suction belt with the ends of the cigarettes prevents the removal of shorts from the cigaretteends, which would otherwise result if the groups of holes extended beyond the ends of their respective cigarettes and thus exposed the same to the action of the suction applied to the belt. However, it will be understood that the invention is not restricted to include perforated suction belts having such registration with the cigarette ends, as the crushing of the same Will be avoided even though the belt is formed of unperforated air-permeable material or Vthe holes in the suction belt are out of registry therewith. For this purpose the belt may be formed of porous material.
