APPARATUS FOR DELIVERING INTO BINS CIGARETTES File d Aug. 2, 1954 WITH MOUTHPIECEI COATINGS- 2 Sheets-Sheet l U.

W., Post Reinbek, Germany,

assignor to Kurt Kiirber & Co. K.-G., Hamburg-Bergedorf, Germany The invention relates to a method and apparatus for delivering into bins cigarettes with mouthpiece coatings or with mouthpiece attachments or the like, leaving a cigarettee machine on two take-oif belts.

In order to be able to bring the cigarettes from the cigarette rod machine into the packing machine or preliminarily thereto into a storage space, they are inserted most conveniently into storage containers, the so-called bins. This is generally effected in such a way that the cigarettes are deposited by hand in the bins from the take-off belts of the cigarette rod machine. Generally two bins are arranged side by side against the side walls of the delivery of the machine, in which the cigarettes are deposited according to the position of the mouthpiece portion. In this case it can however occur that the cigarettes are deposited in the opposite bin and it then requires a longer time to rearrange the cigarettes. Mechanical devices have been proposed for transferring the cigarettes from the take-01f belt directly in the bins. For this reason with mouthpiece cigarettes two bins have been commonly used for the individual take-off belts with the rear walls opposed one to the other. Particular difficulty is encountered in this case in delivering the cigarettes satisfactorily, for it often occurs that the comparatively light cigarettes lie obliquely and thus disturb the filling of the bins. Since two bins are disposed with their rear walls adjacent the attendant lacks visibility and much time is lost if he controls the cigarettes individually for the filling. It is in every case better if the cigarettes are delivered only into one bin in order that the attendant can readily and easily watch the bins from one side and if necessary can immediately remove poorly filled cigarettes.

In order to operate in this case without disturbance it is proposed according to the invention to turn the cigarettes from one belt through 180 on a turning device before entering into the common bin. Thereby it is immediately possible reliably and easily to supervise the cigarettes fed into the bins. As means for turning the ci arettes there may be employed for example two superimposed plates provided with grooves which for example can be constantly pressed together by springs. In order that the cigarettes can be readily introduced into the turning device the plates are somewhat separated from one another by a mechanical device. During the rotation, they lie on the cigarettes and thus prevent them falling out. The turning device is supported in suitable manner on two sides and is rotated each time through 180 by means of an intermittent drive of known type, for example by means of a Maltese cross device.

The features of the present invention are shown as one constructional example in the accompanying drawings in which:

Fig. 1 is a view of the whole cigarette feeder device seen from above,

Fig. 2 is a section on the line A-B of Fig. 1,

Fig. 3 is a section on the line C--D of Fig. 1 and atent O "ice Patented June 3,

Fig. 4 is an end view of the turning device on a larger scale.

The incoming cigarettes with their mouthpiece coatings or with mouthpiece attachments in opposite directions coming from the belts 1 and 2 at the delivery of a cigarette rod machine, oppositely pass into two successively placed supply containers 5 and 6 and fall in this case according to Fig. 2 into the chambers 7, 7' located below them, which for example are divided into separate compartments by partition strips 8, 8'. The supply containers 5 and 6 are arranged one slightly ahead of the other (Fig. 1). The cigarettes are delivered from these compartments in their longitudinal direction by means of sliders 11, 12 which are spaced one from the other and project cigarettes on to a table 21 since the sliders 11 and 12 are provided with

fingers

9 and 10. The cigarettes from the container 6 below the belt 2 are inserted into a reversing device 13 before they are transferred to the table 21.

This reversing device is mounted opposite the container 6 to extend adjacent the lower portion of the container and comprises a pair of elongated plates 14 and 15 (see Fig. 4) which are provided with transverse grooves 16 in opposed faces thereof. The plates are rotatably mounted and at one side there is located a four-part Maltese cross 17 with a 1:2 transmission ratio and thereby the required rotation through can be obtained. Before the cigarettes are inserted into the reversing device positively controlled pins 18 engage from the side between the two plates and release these by a small amount. The upper and lower plates-of the reversing device can be forced together by tension springs 19 located in the two plates adjacent the ends thereof. The pins 18 thus force the plates slightly apart against the force of the tension springs and at the moment of commencement of the 180 rotation again move out of the rotary path of the reversing device 13.

This reciprocatory movement of the pins 18 is effected for example by means of cam discs 18a which are afiixed to the machine frame in any approved manner. After rotation of the

plates

14 and 15 the cigarettes are forced by finger 10 of the slider 12 through the reversing device on to the table 21 whereupon the slider immediately moves back. The reciprocation of the sliders 11 and 12 is effected by means of crank drives 11a and 12a from a shaft 20 which also serves for driving the Maltese cross 17 for the reversing device 13.

Laterally operating

plungers

22, 23 driven in the opposite directions by rocking levers 22a then slide the cigarettes on the table 21 together to such an extent that they come into contact and take the width of the pin 24. T hereupon they are slid longitudinally into the removable bin 24 by means of a slider 26 which is mounted between the containers 5 and 6 to one side thereof and below the level of the fingers 10 also driven by the crank drive 26a from the shaft 20. This bin is supported in the chain drive 25 by which it can be moved slowly downwardly by means of a ratchet device 27 so that each successive layer of cigarettes is disposed on those beneath them.

After a series of cigarettes have been projected into the recesses of the reversing device 13 by the plunger 12 and pins 10, they are projected onto the table 21 by by the abutting ends of the next series of cigarettes fed by the plunger 12 and fingers 10.

What I claim is:

1. Apparatus for delivering to a single handling bin mouthpiece cigarettes arriving from a cigarette machine on two separate belts, and disposed with the mouthpiece ends oppositely on the two belts, comprising a pair of containers for receiving cigarettes from said belts, cigarette receiving means between said containers and "said bin, means to transfer the cigarettes from the two containers to the bin, turning means interposed in the path travelled by the cigarettes leaving the one container to position all the cigarettes reaching the binin'the-same direction, means operable on said cigarette receiving means to bunch said cigarettes together, and :plunger means to project said cigarettes into'saidbin.

2. Apparatus according to claim 1 wherein the turning device is divided into separable parts to grip the cigarettes;

3. Apparatus according to claim 2 wherein theitwo separable parts of the turning device are lifted one from theother :at the moment of insertion of the cigarettes while they are forced one towards the other during rotation.
