one of the side walls are open, which delimit the head at right angles to the axis of rotation, with transfer means for transferring the container into one of the compartments through the associated opening and for removal of the empty containers therefrom, the upwardly opened compartment in the horizontal direction opposite the transfer means and the downwardly open compartment is aligned in the vertical direction with respect to the feed chute, with movable locking elements carried by the head Closing and opening of these upwards and downwards directed openings, with bearing elements for the head, with drive means to turn the head intermittently around its axis and thus to reverse the position of the two inside the compartments Container and with responsive to the cigarette level within the feed shaft means for controlling the drive means Of the head.

As is known, cigarettes are essentially two different ones Ways supplied by the manufacturing machine or the manufacturing machines to the packaging machine, namely:

i) by directly connecting the output of the cigarette making machine with the feed chute of the packaging machine;

ii) by collecting the cigarettes at the exit of the cigarette making machine in containers, which are then emptied into the feeding shaft of the packaging machine.

The present invention relates to the latter area of Technique, according to which the cigarettes are fed to the feed duct in containers.

After the cigarettes have been placed horizontally side by side in the container, they are

In accordance with the known state of the art, either manually or in a semi-automatic manner (see German patent application P 19 39 536.9 of the applicant dated August 2, 1969), or else fully automatic (see German patent application P 25 52 671.0 the applicant dated November 24, 1975) transferred to a facility, which leads to a device located above the feed shaft, by means of which the container contents are in the feed chute is emptied.

According to the applicant's German patent application P 15 86'073.8-27 dated July 24, 1967, the essential component of this device is an essentially cuboid, box-shaped Head leading to an intermittent rotating movement around; one through its center of gravity leading, horizontal axis is caused and which is divided into two compartments by a thin axially extending wall.

The means for storage of this rotary head, which are located on its outer side, ie on both rechtwi.nk ¹ 5g 7Λ \ τ axis of rotation extending end walls rest on the base of the package maker ocler on the bed.

The containers filled with cigarettes that are successively introduced into one of these compartments are then placed in theirs The emptying position is turned over above the feed chute by turning the rotary head over 180. According to a particularly advantageous feature of this device, the next filled containers introduced into the second compartment when the Cigarettes are emptied into the feed tube, and this next filled container will be after it has been completely emptied

(ο

of the first container is in turn transferred to the emptying position by turning the rotary head 180.

The turret is rotated by drive means responsive to the cigarette level within the feed chute.

The containers filled with cigarettes are brought close to the rotating head by intermittently driven conveyors, are according to the already mentioned German patent application P 86 073.8-27 transferred to the rotary head by a process that can be viewed as two-stage, i.e. H. it is done first a sliding movement in a direction parallel to the axis of rotation of the rotary head (or transverse to the cigarette axis) until a Position in front of the empty compartment is reached, whereupon the container into this empty compartment in a direction at right angles is introduced to the axis of rotation.

As is well known, there is an essential condition for proper placement of the cigarettes in the feed tube and thus for a trouble-free operation of the packaging machine in a restriction of the height of fall of the cigarettes inoprlinlb narrower limits when the cigarettes from the twisted container on the cigarettes already in the feed shaft falling down.

If one takes into account that the cigarettes of the packet-making machine are supplied even during the replacement of the emptied container and on the other hand that the for the rotation of the The time required for the rotary head cannot be shortened, the procedure described above can be used for introduction of filled containers due to their complex nature

70 9822/0253

GD SpA - Sr - 2263

lead to a delay in the transfer of another container into its emptying position, with a corresponding Increase in the height of the fall of the cigarettes.

In order to avoid such a disadvantage, the applicant in their patent application P 15 86 073-27, as well as in their patent application P 25 09 659.7 of March 6, 1975 Rotary head proposed in which the introduction of the filled container into the rotary head in a simpler and faster way Way can be done.

The aforementioned process is namely by a single, direct transfer from the conveyor to the rotary head in the direction parallel to Rotary head axis carried out, the introduction no longer frontally but laterally through a normal to its axis of rotation Side wall of the rotary head takes place.

Such a rapid deployment system causes - by necessity the avoidance of the obstacle caused by the mentioned means for mounting the rotary head, which is usually leads to ring nuts on the opposite end walls of the turret - the need to divide the compartments from the axis of rotation to move away, d. H. to increase the thickness of the partition between the compartments, with a consequent increase in the Turning head cross-section at right angles to the axis of rotation.

Taking into account that the opening of the feed chute of the packaging machine is necessarily below the rotary head is located at a distance sufficient to make one rotation of the rotary head, an enlargement becomes

709822 / 02S3

GD SpA - ^ - ²²⁶³

of the turret dimensions are inevitable for the reasons mentioned above lead to an increase in this distance and thus to an increase in the height of fall of the cigarettes, with partial Repeal of such a quick introduction for the container achievable benefits.

Another method of inserting the container that can be referred to as a rapid process because it consists of a single transfer movement from the conveyor to the rotating head is, for example, in the patent application already mentioned P 15 86 073.8-27 proposed.

In this latter case, the introduction of cigarettes takes place filled container and the removal of the emptied container by a vertical movement through in the lower Wall of the rotary head formed openings, or alternatively, in its upper wall.

However, such a system requires avoidance though of occurring when the container is introduced from the side Disadvantages enabled, mutual precautions mn Droliktipf and at the funding agencies, which in practice are not always are executable.

The main object of the present invention is therefore to provide an improved rotary head at which benefits from the use of a rapid insertion system for the containers through one of the side walls at right angles to the axis of rotation are combined with the advantages that result from the use of a rotary head result in minimal external dimensions, and in which the drop height of the cigarettes is actually reduced.

The solution to these and other objects consists in accordance with the invention in that the drive means lead to elements attached to the side wall of the head opposite to that through which the containers are inserted and removed, and in that the drive means are carried by the bearing elements, to support the rotating head in a cantilevered manner.

On the basis of the following description of an embodiment of the invention shown in the drawing, this will be explained in more detail.

It shows:

Fig. 1 is a schematic side view of a with the invention Rotary head-equipped device for supplying the feeding shaft of a packaging machine with cigarettes. and

Figure 2 is a perspective view of the improved rotating head of this invention along with the bearings and Drive means.

Reference is first made to FIG. 1, as well as what is stated in German patent application P 25 09 659.7 of March 6, 2013. 1975 is known. 1 with a total of an intermittently driven horizontal conveyor is designated, which consists of two parallel, endless chains 2, of which only one is shown in Fig. 1, which run on sprockets 3, which in Are driven counterclockwise in the direction of arrow f. Seats for receiving cigarette containers 5 of the introduction described type are formed by bars 4 extending in the transverse direction and arranged in pairs which these chains 2 are connected to one another. The containers 5 are after being filled with cigarettes in a continuous sequence

transversely fed to the right end of the conveyor 1, namely with leading in relation to the direction of movement opened pages. After emptying, the containers are removed from the left end of the conveyor.

A transfer device, generally designated 7, on which a horizontal, reciprocating movement transversely to the conveyor 1 is transferred, is in use at a station 6 arranged in the path of the conveyor.

As also from the patent application

It is known that each container filled with cigarettes when the station 6 is reached during normal operation of the system detected between two vertical arms 8, of which only one is shown in Fig. 1 and the one on the lower run is a component the chain 9 forming the transfer device 7 are attached.

A during a standstill of the conveyor 1 at the same time with this stationary, filled container 5 is through a Forward stroke of these arms 8 in one of the compartments 10 (see also Fig. 2) of a rotary head 11, which at this time also stands still.

This rotary head 11, the axis of rotation of which extends horizontally through its center of gravity and at right angles to the conveyor 1, has essentially a cuboid, box-shaped shape and is limited normal to its axis of rotation by two side walls 12 and 13, which are connected to each other by an axially extending, vertical partition 14 and by strips 15 are connected.

709822/0253

DG SpA - y - 2263

The compartments 10 are a total of these parts 12, 13 and 14 defined. The same compartments 10 are arranged asymmetrically relative to the vertical partition 14 and are each provided with an insertion opening in the side wall 12, which facing the conveyor 1. Two containers 5 can be accommodated by them - one upright, the other overturned and with their open sides resting against the partition wall 14.

This rotary head, to which a rotary movement of 180 in the counterclockwise direction (arrow f ¹ ) can be transmitted by drive means described later, is at a standstill in a position in which one of its compartments 10 is aligned horizontally with respect to the station 6, ready for Takeover of the above-mentioned container 5, while the other compartment 10, in which there is an overturned container and introduced by the transfer device 7 during the work cycle that is now under consideration, is aligned vertically with respect to the feed chute 16 of a packaging machine, which is not shown, whereby this feed chute with Cigarettes is supplied.

Also in accordance with the known state of the art a rotary motion of 180 is transmitted to the rotary head 11 in order to reverse the position of the two compartments if after the Emptying the overturned container 5 of the cigarette levels inside of the feed shaft 16 drops below a preset level, for example by a photocell can be determined, a part of which is identified by 17 in FIG. 1 is.

As a result, the filled container 5 is turned and brought into the emptying position, while the empty container 5

709822/0253 -10-

DG SpA - yd - 2263

is aligned with respect to the station 6, namely between the arms 8 of the transfer device 7. By the backward stroke these arms 8, this empty container is brought back onto the conveyor 1, which is now stationary.

In Fig. 1, 18 square elements are designated, of which each compartment 10 is assigned one and each through Arms 19 are pivotably attached to a shaft 20 which extends parallel to the axis of the rotary head 11 and in is mounted on the side walls 12 and 13 mounted bearings.

If one now looks at one of the compartments 10, it can be seen that the outer end of the shaft 20 is fixed to the outside of the side wall 12 a lever 21 is connected, which at its free end carries a loose roller 22 designed to run along the inner profile of an arched rail 23 which is attached to a support element 24, which in turn is firmly connected to the bed 25 of the packaging machine.

The associated rectangular element 18 is fastened with one end to the side wall 12 by a seated on the shaft 20 and with the other end acting on the arm 19 torsion spring 26, as well as by one on the one hand on the side wall 12 and, on the other hand, the tension spring 27 acting on the lever 21 brought into its position closing the container 5, whereby a Falling out of cigarettes while rotating the rotary head 11 is prevented.

An arm 28 is also connected to the support element 24, to which an oscillating movement is transmitted by known means

GB E ₁ YES - / ι - ^{22 <J} ->

and by which the lever 21 is acted upon in order to overcome the elastic action of the springs 26 and 27 to move the rectangular element 18 from its closed position to its open position to at the end of the rotary movement of the Rotary head 11 to allow emptying of the cigarettes.

The repetition of the cycle described is initiated by that the conveyor 1 is moved forward by one step, whereby the next container filled with cigarettes between the arms 8 are moved, which are at a standstill in the station 6. At the same time, the preceding one, well emptied container 5 moved one step towards the left end of the conveyor.

After the procedure and the already known means for feeding cigarettes into the feed duct 16 a packaging machine have been described, will now be explained in more detail and with particular reference to FIG. 2, as the rotary head 11 is stored and driven.

The mechanism by which an intermittent rotary motion is transmitted to this rotary head and that into the support element 24 is installed, is driven by a motor 29, on whose horizontal shaft a gear 30 is keyed by that a gear 32 connected in a rotationally fixed manner to a shaft 33 is driven via a loosely rotating intermediate gear 31. On the same shaft 33, a conventional device 34 is rotatably mounted, which has a sector 35 and on one side diametrically to an idle roller 36 carries and through which a six-armed Maltese cross 37, which is on a horizontal Shaft 38 is attached, can be driven intermittently.

Also connected to the shaft 38 in a rotationally fixed manner is a gear 39 which is attached to a horizontal shaft 41 Gear 40 is in engagement, the shaft 41 in arranged on both sides of the gear 40 and attached to the support element 24 Bearings 42 is stored. This shaft 41 acts both as a support element and at the same time as a drive element for the Turret 11.

For this purpose, the end of the shaft 41 on the right in FIG. 2, which protrudes from the support element 24, is provided with a flange 43 connected to the side wall 12 of the rotary head 11, which is opposite that side wall through which the container 5 is inserted and be removed.

When the engine 29 is in operation, is thus described by the Transmission connection transmitted an intermittent rotary movement to the rotary head 11, the cantilevered by the Shaft 41 is carried and due to the selection of the gear ratios of the various gear connections for each complete revolution of the shaft 33 and 180 rotated will.

The absence of any support and / or drive elements on the side wall of the rotary head, through which the container 5 in the Compartments 10 are introduced and removed from these, in contrast to the previously common devices the direct transfer from the conveyor 1, while at the same time due to the theoretical possibility two compartments 10 side by side To be arranged along the central plane of asymmetry of the rotary head 11, the overall size of this rotary head 11 is substantial can be reduced.

It can be mentioned that the vertical wall or partition 14 can be reduced to a thin partition, but in practice it cannot be completely omitted because it is required to keep the cigarettes in the containers 5 during the rotation of the rotary head 11.

From the above it can be seen that the inventive device compared to known devices sure a substantial reduction in the distance between the opening of the feed chute 16 and the emptying opening of the rotary head 11 allowed and thus another Reduction of the height of fall of the cigarettes, which turns out to be an important improvement in the operation of the packaging machine as well as for Avoidance of the in the preceding description introduction has shown the disadvantages.
