In machines for packing goods in containers, for instance for packing cigarettes in packets, it is always necessary tojnsert a definite quantity of the goods in the packet. For instance, ten

or twenty cigarettes may have to be inserted in the packet.

It is usual to provide a regulating device which checks the accuracy of the amount of the goods to be transferred to the container. Herein it has been found advantageous not to separate the incorrect quantity detected by the control device, but, in order not to interrupt the operation, to pack the respective container; on the other hand, the regulating device is arranged so that, at the end of the operation, it deals with the reject or incorrectly packed containers at the position where the articles are delivered from the packing machine.

The invention relates to a device which solves this problem and, without the use of complicated control devices or the like, ensures that the faulty article is thrust aside merely by the following article and removed from the further course of operation.

For this purpose the finished articles are thrust on a movable support which is controlled in such manner that the oncoming articles are deposited in ordered sequence at a position for further delivery, whereupon, however, the control device sets a locking member in operation which interrupts the action of the support, as soon as the waste article arrives on the support and consequently the next article thrusts the waste article from the stationary support on to a discharge.

The support is preferably constructed in the form of a rocking lever which in horizontal positions receives the oncoming article, and by. pivoting 90 delivers the article to the position for further delivery, the rocking lever being, turned 40 by a gearing actuated by a cam or the like, while the rocking lever is held in horizontal position by a locking lever which is withdrawn at the right moment by the control device.

The arrangement can be so constructed that the control device acts upon a disc provided with control pins; the pins of this disc, which are adapted to be displaced axially in the vicinity of the periphery of the disc, can be brought into contact with an inclined surface on a locking lever; the control device actuates a pin which acts upon the locking lever only after the passing by of a number of pins corresponding to the'number of packets which are between the control position and the removal position influenced by the looking lever.

The invention is illustrated in the annexed drawing, in which:--

Fig. 1 is an elevation.

Fig. 2 is a side view.

Fig. 3 is a partial view, partly in section on 6 the line 3-3 of Fig. 1.

Fig. 4 is a detail view.

Figure 5 is a side elevational view of a control device, and Figure 6 is a front elevational view of a portion of said control device. 10

The articles thrust forward on the guideway in the direction indicated by the arrow in Fig. 1, pass serially to a plate 2 mounted on the pivot 3. To the pivotal axis 3 is connected a spur wheel 4 with which the toothed segment 5 mounted on the lever 6 engages. The lever 6 is adapted to pivot about the pin 1 and by means of the roller 8 on the lever arm 6 comes into contact with the cam 9 which, when a new article arrives on the plate 2, describes a full revolution about its axle l0. Now when the cam 9 has arrived in the position shown in Fig. 2, the lever 6, 6' has passed, under the tension of the spring ll, into the position indicated. by dotted lines in Fig. 2. The pivoted plate 2 has passed into the position indicated by dotted lines in Fig. 2 and has swung the article W resting on it on to a slideway l2, which transfers the article to a conveyer belt l3 movingin the direction indicated by an arrow in Fig.2. 2

Now at a: (see Fig. 1) a control device of known type is arranged on the guideway l which, in the event of the article arriving at m being faulty, releases an electric current which excites the electro magnets i4. Thereby an armature l5, connected to the electro magnets. and pivoted at I6, is drawn into the position indicated by dotted lines in Fig. 3.

Now two interconnected discs l1 and H are fitted to the control device, which discs are mounted on the support I8 and rotated by actuating gear not shown, in such manner that when each new article arrives on the feedway the bolts l9 mounted therein are rotated a step further. In the'discs I! or l1 the bearings 29 and 2| are mounted so that their bores are opposite one another. Now while the bearings 20 are test in the disc l1 and are provided with keyways for the keys l9 attached tothe bolt [9, the bearings 2| are adapted to rotate. In the bearing 2| a pin 22 is inserted, the front end 22' of which engages in an oblique groove in the bolt l9.

Now if the armature i5 is drawn into the position indicated by the dotted line in Fig. 3, by a faulty article by the agency of the magnets I4,

the respective bolt I9 then remains unchanged as regards its position. Now when the faulty article in question arrives on the plate 2, the respective bolt has just entered within the range of the bell crank lever 23 which pivots about the pin 24 and is under the tension of a spring 25. The roller 26 on the bolt I9 then passes under the end 23 of the bell crank lever 23 and moves it into the position shown in full lines in Fig. 2. In this operation the hook-shaped end 23" of the bell crank lever 23 has placed itself in front of the end 2' of the pivoted plate 2, thus looking it. The plate 2 and the 'bell crank lever B, B'are now unable to follow the spring I I when the cam 9 has assumed the position shown in Fig. 2. If intermittent advancement of the articles on the guide I now takes place, then the faulty article resting on the pivoted plate 2 is thrust down by the latter on to an oblique slideway 21, which passes the faulty article to the waste collecting vessel.

If, on the other hand, the article which has arrived in the position a: (see Fig. 1) is faultless, the electromagnet I4 is not excited. Thus the armature l5 remains in the position shown in Fig. 2 in full lines. Now, on further rotation of the discs IT, IT, owing to the fact that the pin 22 comes into contact with the armature I5, the bearing 2| is displaced into the position shown in Fig. 4. Thus the bolt I9 is thrust in the direction indicated by the arrow in Fig. 3, so that the corresponding bolt l9 and the roller 26 connected thereto assume the position shown in Fig. 4. If now this withdrawn bolt comes within the path of the lever 23 then, as the roller 26 is in the position indicated in dotted lines (see Fig. 2), the lever 23 cannot swing from the position indicated by the dotted lines (Fig. 2). If, however, the lever 23 is in the neutral position (see dotted position in Fig. 2) the pivoted plate can be turned by the cam 9, and therefore the faultless article thereon can be deposited on the slide- Way I 2.

It is self-evident that all the bolts I9, before again entering within the path of the armature I5, are returned to their initial positions (see Fig. 3).

The control device shown in Figures 5 and 6 will now be described. The guideway I is indicated with the package W thereon with the cover in open position. Adjacent the guideway as shown is a slide 12 adapted to reciprocate upon the vertical rod a. The reciprocation of the slide b is accomplished by means of the cam disk (1 through the crank rod 0 from the rotating shaft carrying the gear 1' which may be rotated from any desired portion of the machinery. The slide b is reciprocated whenever a new object reaches the point x in Figure 1. Extending from the slide 17 is an arm 17' which carries the head f which extends directly over the guide path I.

In the head 1 there is a series of feeler fingers e which correspond in number to the number of cigarettes in the package. Encircling the fingers e are the springs g which tend to force the contact members e against the insulated contact bar h which is attached to the head 1. A connection is made between the contact bar h by means of the wire i with the contact member is upon the slide b. When the slide b is in lowermost position, contact member is will make cont-act with the contact spring I carried by'the rod a.

The current supply is indicated at m and one circuit extends through the bar a and the slide b while the other circuit goes through a wire q, contact Z, contact k, wire 1' and contact h. The electromagnet l4 shown in Figure 3 is connected in series with this circuit so that if the feelers are not all pressed away from the contact bar h, then a current is set up through the electromagnet which will actuate the armature I5 for axiallly displacing the control pin 22 upon the disk As soon as a new article arrives at the point :0 shown in Figure 1, the slide 2) is lowered due to the cam disk d which is driven for instance from the shaft I0 through a chain drive or the like. The fingers in the head 1 are thereby moved on coming into contact with the cigarettes, upwardly in the head 1 so that the contacts e are disengaged from the bar h. It is obvious that only when the number of cigarettes in the package W is incomplete does the corresponding finger or fingers e for which there are no cigarettes, remain in the lower position, thereby making contact and actuating the electromagnet I4.

It is of course obvious that the package must be open at the point a: in order to. allow the coh- An apparatus for sorting articles comprising conveying means for articles delivered from a packaging machine, control means located adjacent said guideway for detecting imperfect articles, a second guideway extending from said first guideway, a deposit station located at the end of said first guideway, means for oscillating said deposit station through an angle of substantially 90 to deliver the article received upon said deposit station to said second guideway, said control means controlling the operation of said deposit station, means controlled by said control means for preventing the oscillation of said deposit station when an imperfect article rests thereon, a third guideway, and means for feeding said imperfect article from said station to said third guideway.
