Device for dispensing parallel rod-shaped objects from a container

The invention relates to a device that can be used in connection with a container in which generally stick-shaped objects, in particular cigars or cigar bundles, which are arranged parallel to one another is, and according to the invention the device is provided with a discharge mechanism or a slide, the upper end of which communicates with an opening in the bottom of the container and which can be moved to and fro with respect to the container, that it executes movements transversely to the longitudinal axis of the objects.

In known arrangements of this general type is the Bottom of the container formed by the cylindrical outer surface of a component resembling a piston that rotates back and forth and is provided with a discharge chute extending in a diametrical direction the object »in the container is largely prevented by that the inlet opening of the shaft is movable to and fro in the bottom of the container.

With these known arrangements, however, there is a disadvantage that the objects are pressed against the edges of the inlet opening of the chute, and that the objects are set in rotation by the friction between them and the movable cylinder surface, so that sensitive counter-

Items such as cigars, cigar bundles and cigarettes easily damaged can be.

The object of the invention is now to provide an arrangement in which the disadvantages just mentioned are avoided and which also require considerably less space takes as the arrangements known up to now.

For this purpose, the device provides that the bottom of the container has two parts extending in the longitudinal direction comprised of a very flexible material extending transversely to the axis of the objects and supporting them; here Each of these base parts is attached to one of two opposing side walls of the container, and each The bottom part is held taut by a tensile force acting on it; Each bottom part extends towards the other Bottom part as well as one of two rollers, which are rotatably mounted with their axes parallel to the axes of the objects and with are connected to a support piece which can be moved relative to the container is; the distance between the two rollers is adapted to the width of the discharge chute.

An important advantage of the device according to the invention is that the bottom of the container opposite the container is essentially immobile. Therefore, the objects lying on the container bottom are not given any rotational movement when the shaft moves past one of the items, and the item to be dispensed first moves down into the inlet opening of the shaft into it, whereupon the object under the inevitable influence of the load-bearing components is moved up again at the edges of the shaft; therefore the object undergoes a continuous undulating motion the end.

The two supports can each comprise a wide band, for example made of rubber or a plastic, or two parallel thin bands or strips, and the supports have free ends, each around the associated roll are laid out. The rollers can also be used in a similar way to belt pulleys

"ben trained, and the supports can be on separate Be wound up and unwinding rolls, which are rotatably mounted in the movable support piece.

In order to keep the supports taut, the rollers must be driven for winding and unwinding on both supports-_L will; this is conveniently done by providing the rollers with sprockets that work together with a chain, which is fixedly arranged opposite the container; alternatively, a corresponding gear can be provided that for example, comprises a gear and a rack. Furthermore, the roles can be connected to one another by a chain, so that the Take-up reel is driven by the supply reel. It's easier to keep the supports taut when using them the container or a component connected to it are connected with the aid of elastic fastening members. The drive of the Winding roller and the unwinding roller during the simultaneous elastic expansion of the supports can also thereby the effect is that a constantly acting torque is applied to the lump, e.g. with the help of long coiled springs, that between the moving part of the frame and the rollers come into effect. If sprockets, gears or the like are used to drive the rollers, a rotating force can result elastic members are applied, which are arranged between the sprockets and the rollers.

In a simple embodiment of the invention, each support part extends around one of two further rollers which are mounted on the movable frame part, and each support part has a free end which is firmly connected to the container or the end of the same component which is attached to the side wall of the container. This embodiment has the same space requirements in the direction of movement of the movable frame part as the known arrangement with a rotatable cylinder surface. However, a reduction of the space requirements can be easily achieved, wc ^ nn inar .. the two lines supporting members to one another via rollers of which are arranged stationary in relation to the container so that an endless loop entsteh fe ₄ When the support member is a cln ^ ses wide band

Fig. 2 shows in a partial representation an example of a device for driving a take-up roll or a Unwinding roll.

Fig. 3 is a partial section through that shown in Fig. 1, the press chambers comprehensive conveyor belt.

Fig. 4 shows a partial representation of a modified one Embodiment of the winding and unwinding rolls according to FIG. 1.

Figs. 5 to 8 show four further embodiments of the Invention each in a vertical section.

The device shown in Fig. 1 comprises a frame 1 on which a container 2 for cigars is arranged. Furthermore is a movable frame part 4 is provided on two guide parts 3 is displaceable in the longitudinal direction.

One end of a wide belt 5 made of rubber is on the frame 1 attached by means of springs 6. The belt 5 extends from the lower edge of a side wall 7 of the container 2 Via a pulley 8 which is rotatably mounted on the frame part 4 is, and then runs over a roller 9 'which is also rotatably mounted on the frame part 4 and on which the other end of the Belt is attached. Accordingly, a second belt is on the other

Ren end of the frame 1 with the help of springs 11 attached. The belt IO extends from the lower edge of the side wall 12 of the Container from via a pulley 13 'which is rotatably mounted on the frame part 4, and it is with its other end a roll also rotatably mounted on the frame part 4 is wound up ^

The frame part 4 also carries a deflection roller 15j which runs a conveyor belt 17, which is provided with numerous pressing chambers 16, and two pulleys 18, which with the top of the longitudinal edges of the belt 17 outside the press chambers cooperate so that the belt 17 along a generally S-shaped track moves. When part of the tape 17 over the Deflection roller 15 runs and is bent in the process, expand the chambers 16, and at this point the outlet opening of a channel or shaft 19 is arranged on the frame part 4, by means of which the pressing chambers 16 cigars 20 are fed. The upper end of the channel 19 is in the space between the pulleys 8 and 13 arranged, within which the cigars fall into the channel 19.

The belt 17 is moved step by step in the direction of arrow 21, for example, and cigars are only released during the idle times fed to the pressing chambers 16 · For this purpose a locking arm 22 with a locking plate 23 on the movable frame part mounted so that it is between two stops 24 can be moved so that the locking plate 23 can be arranged under the outlet opening of the channel 19 can.

With the locking arm 22 is a straight back and forth movable rod 25 connected, averages both the movable Frame part 4 and the locking arm 22 is actuated. The take-up reel 9 and the supply reel 14 are each provided with a sprocket 26 firmly connected to it, and these sprockets work with a chain 2? together that is fixed to the frame 1 when the movable frame part 4 is moved; the initial angular position of the rollers 9 and 14 is bo chosen that the belts 5 and 10 in the required

evidence is curious.

The operation of the device according to FIGS. 1 to 3 is described below. While the belt 17 is at rest, the rod 25 is moved in the direction of arrow 28 by a device (not shown); Here the arm 22 and the locking plate 25 are brought to bear on your stops 24 so that the stack of cigars 20 contained in the channel 19 can slide down a short distance until the lowermost cigar has been received by a pressing chamber 16 ; then the movable frame part 4 is moved together with the rollers 8, 9> 13 »14-» 15 and 18, so that the channel 19 also executes a movement. In this case, the chambers 16 are successively expanded by the rollers 15 and 18, so that each chamber can receive a cigar 20 from the channel 19. At the same time, the tape 10 is unwound from the roll 14 and the tape 5 is wound onto the roll 9, while between the rolls 8 and 13 cigars fall into the shaft 19, each chamber 16 being supplied with a cigar. When the ⁵ shaft has reached the side wall 7 of the container 2, the movement of the frame part 4 is interrupted and the rod 25 is moved in the opposite direction. Here, the locking arm 22 is pivoted counterclockwise and brought into contact with the other stop 24, the locking plate 23 taking up a position below the outlet opening of the channel 19 "so that the downward movement of the cigars in the channel is interrupted; then the movable Frame part 4 from a backward movement until the channel 19 is in close proximity to the side wall 12 of the container previous work cycle; this movement of the belt 17 is most expediently brought about during the backward movement of the movable frame part M. If the speed at which the belt 17 is moved is not too high, the relative speed between the belt 17 and the movable frame part 4 be sufficiently low so that cigar ren from channel 19

au the chambers 16 also during the backward movement of the movable Frame partly 4 can be given away; in this! '' all the locking device 22, 23 can of course be omitted.

If a certain deviation of the shaft between the belts 5 and 10 may be admitted above the channel with respect to the width, it is possible, the take-up roll 9 and the unwinding roller 14 of FIG. 4 d ^r rt arrange where according to Figo 1, the guide rollers 8 and 13 are located; this reduces the space required by the device «

Fig. 5 shows a further modification of the arrangement according to Figures 1 to 3; iii in this case each of the support members 5 and designed in the form of an endless belt. The in x'g. 1 shown winding roller 9 and the unwinding roller 14 are omitted, and the endless belts 5 and 10 run over zv / ei further mf Aem movable frame part 4 rotatably mounted circumferential rollers 29 and 30, and both ends of the belts are directly on the container 2 attached. In this case "C it is not necessary wind up and unwind the tapes and therefore mpn does not need any Device for driving the winding and unwinding rollers.

The same goes for those in i'ig. 6 shown embodiment, in which a single wide band 31 of great length the side wall 7 of the container 2 is attached and over the pulley 8 on the movable frame part 4, over on the Frame 1 rotatably mounted rollers 32, 531 34, 55 and over the Deflection roller 13 runs on the movable frame part 4 and finally with its other end on the side wall 12 of the Container 2 is attached. Instead of a wide band 51, two parallel narrow bands or cords can be used; in this The case is the loop running over rollers 33 and 34 divided into two parts that can be guided directly between rollers 32 and 35 on both sides of the container. the The arrangement shown in FIG. 6 enables the cigars 20 to be fed downwardly to open chambers of a belt 37 which, in the direction of of arrow 36 is incremented, while the movable Frame part 4 is moved in both directions. To the feeder

of cigars via the channel 19 at the reversal points of the movable To interrupt frame part 4, two locking plates 38 and 39 are attached to the reversal points on the frame 1, which fulfill the same task as the movable locking or locking plate 23 shown in FIG.

In some cases it is desirable to open the lower outlet. ^ rmng of the feed shaft stationary opposite the frame to arrange. In the invention, this only means that the container in which the ends of the fastener tapes are close to each other opposing walls of the container are attached to this, must be movably mounted relative to the delivery shaft. In the embodiments described above, soä must with the movable frame part 4 together with the associated Parts can be arranged in a stationary manner in a frame, while the container 2 together with the stationary opposite it Parts must be arranged on a movable frame part. In most cases, however, there is a more appropriate one Solution is to mount the movable frame part 4 rotatably on an axis which is in the area of the lower outlet opening of the Channel is arranged parallel to the longitudinal axis of the objects to be dispensed. Such an embodiment is shown in Fig. 7; in this case the cigars are conveyed to an endless conveyor belt 38 one after the other in the direction of their longitudinal axis Also given that it is driven with the aid of rollers 39 '. That movable frame part 4 is mounted on bolts 39, the opposite the end walls of the frame part 4 protrude outwards, and which are provided with an arm 40 on which a reciprocating Operating rod 41 is articulated.

The pivotable frame part 4 can also be mounted on pins or bolts, which are offset further upwards compared to our end of this frame part j and, for example, can be arranged approximately in the middle between the ends of the channel 19, and devices of a known type can be provided, dic allow the GesLellteil 4, respectively deliver xu only one position or in Jedor of the two possible positions ^ inen object.

In all of the exemplary embodiments described so far it may be useful to arrange the movable frame part 4 and the support arm so that it is possible, if necessary, to move the frame part far enough beyond one of the reversal points so that the upper opening of the shaft 19 does not more of the relevant side wall of the container is covered. This measure enables the shaft to be closed in a simple manner empty the container first, without the need to empty it 2 to remove objects.

The invention can also be used in an advantageous manner in cigarette packaging machines in which it has been used up to now it is difficult to cause cigarettes to be dispensed from one container in a sufficiently uniform stream and several parallel feed channels are fed. The irregularities that occur here are primarily due to this causes the cigarettes to a considerable extent to tend to clog a dispensing opening in the container "Bridge" to form, as well as the adverse effects of Vorrichtv igen that are to prevent this sticking, but the Obstruct the downward movement of the cigarettes in the direction of the opening at the upper end of the shaft. With one type of such Machine moves a group of cigarettes from the lower part of the feed channels towards a stationary one Container advanced; this container is placed on a conveyor belt that can be moved step by step * The "several Manhole comprising channels and the container can, for example, according to the inFig. 1 construction shown. The transfer of the groups of cigarettes into the container can expediently take place when the shaft is in the middle is located between the container walls 7 and 12, and you can do that form movable frame part 4 so that it alternately moves in the direction of the wall 7 and the wall 12 and between the Exercise "leadership processes" is traced back to the various To fill the ducts of the shaft with cigarettes.

However, it is particularly advantageous to apply the invention to a cigarette packaging machine of a different type, with the groups of cigarettes with the help of a movable

01961

lichen slide from the channels in on a continuously moving conveyor belt arranged holder are transferred. If one sees according to the invention that the shaft moves back and forth the groups of cigarettes can be transferred into the holder using a movable carriage, and at the same time it is possible to prevent the cigarettes from getting stuck above the chute without having to do any Needs to provide device in the container. Such a construction is shown in Fig. 8; she distinguishes differs from the embodiment according to FIG. I in the first place in that the shaft 19 is divided into several channels, with the help of partitions 42, at their upper edges Rollers 46 are rotatably mounted, the axes of which extend parallel to the axes of the cigarettes 20, and that the groups of cigarettes in the direction of their longitudinal axis from the lower part of the shaft 19 with the aid of a slide that is not shown a delivery device to the holders 43 arranged on a continuously moving conveyor belt 44. It is ensured that a group of cigarettes is dispensed each time the movable frame part 4 according to FIG. 8 in the direction of arrow 45, which simultaneously indicates the running direction of the conveyor belt 44, the lower part of the shaft 19 being arranged directly in front of a holder 43 is. When the group of cigarettes has been introduced into the relevant holder 43, the slide of the dispenser becomes withdrawn, and the frame part 4 moves back to the container wall 7, while the channels with cigarettes filled. The time available to fill the lower part of the channels with cigarettes is considerably longer than in constructions in which groups of cigarettes from a stationary shaft to a moving holder with With the help of a movable slide, the basically forms the lower part of the shaft, because the cigarettes have to be on the slide within an extremely short period of time be fed while the carriage is in its initial position at rest.

In order to facilitate the feeding of cigarettes to the upper part of the shaft 19 eu, the rollers ^ -6 are useful

driven by a belt made of rubber or the like, which is so driven by one of the rollers 8 and 13 or both rollers is that the direction of rotation and the peripheral speed of the rollers 46 of the direction of rotation and the peripheral speed the roles 8 and 13 corresponds.

In the exemplary embodiments according to FIGS. 7 and 8, the rollers 9 and 14 are driven either in the manner shown in FIG. 1 using one of the methods mentioned in the introduction. Of course, one can also omit the rollers 8 and 13 and replace si ¹ ″ by the rollers 9 and 14 in the manner shown in FIG.
