In packeting machines, more particularly for packing cigarettes or the like rod-like articles, it is already known, for transferring a number of articles to be packeted from a conveyer band moving forward continuously to another conveyer band running parallel thereto, to employ a pusher or ram, the operative face of which lies parallel to the conveyer band, and which in its movement towards the articles participates at the same time in the longitudinal movement of the conveyer band in the longitudinal direction of the said band. In a known construction of a device of this type, the ram or pusher is actuated by means of two cranks or eccentrics or the like.

In this case, however, difficulties arise when the machines run at a particularly high speed, because the complicated type of driving means does not always work with thorough accuracy, due to the possibility of play being set up, and consequently such driving means is only applicable for slow-running machines.

The object of the present invention is to provide a device, in which, due to the simplest possible construction and the improvement of the means for driving and guiding the ram, any play ispractically impossible, and satisfactory and accurate working is ensured. For this purpose, according to the invention, the pusher is reciprocated in a guide inclined to the conveyer band, so that the said pusher can be driven by a single eccentric, cam or the like.

A construction of the invention is shown by way of example in the accompanying drawing, wherein: I

Figure 1 is a plan of the construction,

Figure 2 is an elevation and Figure 3 is a diagrammatic illustration of a part of the device on a larger scale.

Referring to the drawing, a is a conveyer band on which the articles to be packeted, for example cigarettes, are fed. As shown by Figure 3, the band is preferably provided with trough-like depressions a in which the articles to be packeted, that is to say the cigarettes, are situated. The band is moved forward continuously by a device not shown in the drawing, and the cigarettes or the like, lying in the troughs a are to be transferred to an adjacent, stepwise moving band. As shown in Figure 3, this latter band I) is also provided with troughs b for the reception of the individual cigarettes, the'said troughs b being preferably flared funnel-fashion at the receiving end in order to facilitate the introduction of. the cigarettes. In Figure 3, a cigarette Z is shown in its position on the conveyer band b. The

transfer of the cigarettes from the one band to the other band is effected by means of a pusher 'c, which (Figures 2 and 3) is preferably constructed in the form of a comb on the side facing the band a, that is to say, it is. provided with 5 two guide bars 1 and f fixed to the machine 5 frame. The direction of the guide bars I and f is inclined to the conveying direction of the two conveyer bands a and b. Consequently, when the cross-head c with the bell crank lever d and d slides in the direction towards the conveyer band a, the bar c makes an oblique movement, namely, in the first place a movement transversely to the conveyer band a, by which movement it pushes the cigarettes 01!? the conveyer hand a and onto the conveyer band b, and simultaneously a'movement with the conveyer band, this latter movement being necessary, because the conveyer band a, of course, is moving continuously. Of course, the transfer to the conveyer band b is effected at the instant at which the conveyer band b is moving in the same direction and at the same speed as the conveyer band a. Thecrosshead e is driven by means of a lever g, which is pivoted at o to the machine frame and carries a roller 0', running in a groove ina camdisch. .'1heleverg is connected to the cross-heads by an arm i. The end of the arm i engages the forked end of the iever'gby means of a pin.

0n the same spindle as the cam disc it there is mounted another cam disc k, on which runs the roler m of a double lever 11;. rotatable about a spindle m". The other end of the said double lever is pivoted to a yoke n. In addition, there isprovided a link 0 one end of which likewise engages the yoke n, while the other end of the said link 0 is pivoted to the machine frame. The lever m and the link 0 constitute a parallel guide. Consequently, when the roller m runs on the cam disc 7:, the yoke n will be raised and lowered. The yoke 11 has secured to it a guide 11 on which the roller d runs. The cam discs h and k are driven off the shaft (1 of the machine by means of a pair of bevel gears r, 1' The device accordingly functions as follows: While the two bands 11 and b are running at the same speed and in the same direction, that is toward the right in Fig. 1, the cross-head e is moved by the lever g along the guides and f and consequently the bar c makes the oblique movement having components in the transverse direction and in the longitudinal direction of the conveyer band a, that is to say, it transfers the cigarettes to the band b, and at the same time, due to the inclined position of the guides f, I, it participates in the longitudinal movement of the conveyer band a. During this time, the guide bar .17. is stationary, since the roller m is running on the cylindrical part of the cam disc k. At the end of the forward movement, the roller m runs on to a rise on the cam disc k, consequently the yoke n with the guide p is lowered, the result of which is that the roller d running along the guide p is pressed downwardly and rotates the lever 11 and d with the pusher c in a counterclockwise direction in Figure 2, so that the pusher c is raised. This raising is necessary in order that theconveyer band a can move further continuously during the return of the pusher into its initial position. After the raising of the pusher c, the return movement of the cross-head .e is eifected by means of the lever 9. At the same time, the pusher c moves over the band a back into its initial position, and at the end of its return movement, it is again lowered upon the band (1, because the roller m then runs oil the higher cylindrical part of the cam disc k. Consequently, the yoke n is again raised and the device is again in its initial position. Accordingly, the cam disc k is provided with two cylin-' dn'cal parts k and k which engage the roller m during the forward and return movement of the cross-head, and with rising and falling parts connecting the two parts 10 and k Of course, other mechanisms may be employed for carrying out the various movements. For example it is also possible to employ an intermittently actuated rack gear for the upward and downward movement of the yoke, and an eccentric mechanism or the like may be employed instead of the cam mechanism for the forward movement of the cross-head.

I claim:-

1. A device for efiecting the transfer of a number of articles to be packeted, as cigarettes or the like, from a conveyer band moving forward continuously to a conveyer band running parallel thereto, comprising, in combination with the conveyer bands, a pusher, the operative face of which lies parallel to the conveyer bands, a cross-head, on which said pusher is pivotally mounted, a guide inclined to the conveyer bands on which said cross-head is reciprocated to move the pusher obliquely of the bands, means for reciprocating said cross-head, and means co-opcrating with said pusher at the end points of the reciprocating movement and adapted to turn it upwardly or downwardly.

2. A device according to claim 1, in which the last mentioned means comprises a guide engaged by said pusher and along which the pusher runs and a mechanism adapted to move said guide upwardly and downwardly thereby turning 'the pusher at the end points of the reciprocating movement upwardly or downwardly.
