(ci. ies-209) My invention relates to an apparatus for handling for example packing bulky or fibrous material such as tea, tobacco or the like, or indi-Y vidual articles such as cigarettes.

In hitherto used apparatus of said type a plurality of sleeves adapted to receive the material have been arranged in equal intervals upon a drum or other support which has been discontinuously rotated to bring one sleeve after another into an operative and temporarily stationary position. This known apparatus had many disadvantages Thus said drums or supports had to be quite heavily built and their considerable mass being repeatedly accelerated and decelerated during the interrupted rotation influenced unfavorably the operation of the apparatus. This made it impossible to increase the rotational speed of said support in order to increase the output of the apparatus.

The main object of my invention is to avoid the said disadvantages and to provide an apparatus of said type which is simple and reliable in construction and efficient in its operation. According to my invention the sleeves or sleeve groups are arranged at the tips of supporting arms which are pivoted upon a uniformly rotating driving member and said sleeves are in intervals temporarily accelerated and decelerated to counteract the eiect of the driving member upon said supporting arms and the sleeves connected thereto and thus to temporarily stop the rotational movement of the sleeves or sleeve groups While the material or articles are handled by and in said sleeves.

The said and other objects of my invention l will be more fully understood from the following specication when taken with the accompanying drawing in which three embodiments are illustrated. lIn the drawing:

Fig. 1 is a sectional view of one embodiment of my new apparatus;

Fig. 2 is a top view thereof,

Fig. 3 isa schematical showing later described in detail,

Fig. 4 a partial sectional View of another embodiment of my apparatus,

Figs. 5 and 6 are top views thereof illustrating two different positions, and

Figs. 7, 8 and 9 illustrate in top view a further embodiment in three diiierent positions.

The same reference characters indicate the same or equivalent parts in all figures of the drawing.

Figs. 1 and 2 show a vertical pivot 2 with base plate .2 mounted upon the machine base I.

Concentrically surrounding said pivot 2 is a cam plate 3 also mounted upon the machine base I and having upon its top face an endless non circular groove or` race I8. This groove I8' is adapted to guide a series of horizontally turnable rollers I8 to impart to them a predetermined inward and outward movement relative to the pivot 2 for a purpose which will be later described.

Journaled upon said pivot 2 is a driving member comprising a circular disc 4 with a peripheral toothing. Said disc d is arranged above the cam plate 3 and is provided with a hub II extending along said pivot 2 and terminating in a head plate 4". Said driving member is continuously and uniformly turned about the pivot 2 in any suitable manner in clockwise direction indicated by the arrow in Fig. 2, for example as shown by the pinion 5 which meshes with the toothing of the disc 4 and is driven by the sprocket wheel 9 and the intermediate bevel gear drive 6, 1, 8.

.A series of 'vertical spindles I0, eight in the shown embodiment, are equidistantly spaced in a circle around the pivot 2 and each spindle is journaled with its ends in the driving disc 4 and the said head plate 4, respectively. Each of said vertical spindles lilhas attached thereto at its upper end a radially extending arm or carrier lI supporting on its free end a packaging sleeve I2 or the like and at its lower end an essentially radial lever I3. The free end of each lever I3 is connected by a link I4 with an essential radial lever I5 which together with the trailing lever I'I arranged below the driving disc 4 form a bell crank lever turnable upon the short vertical pin I6 journaled in said disc 4. Each of said lower levers I'I is provided with a horizontally turning roller I8y which travels in the endless cam groove I8 as valready mentioned above. The circular portions of this groove I8' are interrupted by non circular portions which effect a rocking movementY of the levers I1 about -the pin I5. This movement is transmitted by the lever I5, the link I4 and the lever I3 upon the spindle II) so that the same isV angularly displaced relative to the driving member 4 rotating in clockwise direction. It will be easily understood that each of the spindles I0 will be partially turned-in anticlockwise direction when Vthe yrespective roller I8 while traveling in the groove I8 moves away from the rotational axis of the driving member 4, thus ret'arding the rotational movement of. the respective sleeve I2 con- -nected through the arm I I to the spindle I, and

that each of the spindles will be partially turned in clockwise direction when the respective roller I8 while traveling in the groove I8 moves towards the rotational axis of the driving mem.- ber, thus advancing the rotational movement ci the respective sleeve I2. It will be further understood that each sleeve I2 may be kept transitively at rest in case that the speed of said retardation will equal the circumferential speed imparted by the uniformly rotating driving member el. Any expertV in the art will' be in a position to design said non circular groove IS so that each sleeve I2 will be retarded, advanced or stopped for a certain time interval at any desired place during the rotation of the driving member 1i.

Fig. 2 shows each of the eight sleeves I2a, IZb, I2c through I'Zb in its particular position relatively to the driving member 4 while they rotate with the latter. In the shown embodiment it is assumed that each of the sleeves I2 has to be transitorily stopped when reaching during its rotational movement the positions I (sleeve Ita), II (sleeve I2C) and III (sleeve |26) to allow the performance of a certain operation for example to receive the wrapper in position I, to ll the wrapper in position II, and to close the wrapper in position III. The sleeves I2a, I 2c and IZe are shown during said transitory rest period. This rest period will continue while the respective roller I8 moves in the groove IB away from axis of rotationv of the driving member li and eiects a compensation of the rotational movement of said sleeve. When said roller I8 reaches the adjoining circular portion ci the groove IBl no relative movement between the sleeve I2 and the driving member i will occur. When thereafter the roller I2- while traveling in the groove I8 moves towards the said axis'o rotation, the bell crank levers I'I, I5 will be turned in an anticlockwise direction causing an acceleration in the movement ofthe respective sleeve I2. When this sleeve reaches an intermediate position such as I2b or I2d the respective roller I3 will start to move away from said axis of rotation and will continue to do so until the respective working or rest position |211, I2C, I'Ze, respectively, is reached. During the respective time interval the sleeve remains at rest in position I2C. scribed before are repeated when the sleeve moves from position I2C over the position I2d into the transitory rest position I 2b, and again while the sleeve continues to move over the positions I2f, |29' and IZh into the first mentioned position I2a. The cycle described before is repeated as long as required to perform the different oper ations as related above.

Fig, 3 shows diagrammatically the movement of one supporting arm II with sleeve I2 while the spindles I2 are partially turned as described above at rst clockwise and then anticlockwise in order to compensate the rotational movement eiected by the driving member 4- so that the sleeves are kept temporarily in an at least essentially stationary position while the material is handled by and in said sleeves. In this Fig. 3 three succeeding positions a, c, b, of the spindle IIB are shown while. the driving member turns in clockwise direction about an angle a. As described above the arm II supporting the sleeve I2 isy turned at rst clockwise about' the spindle II) whilethe same moves from'V position fa, to positionc and thereafterv anticlockwise while the spindle III moves from position c into the The relative movements deposition b1 said a-rm II thereby attaining successively the positions indicated by the lines Ila, IIc, IIb, respectively. It will be evident that the sleeve I2 will remain basically stationary duringy this period although it will only very slightly be moved away from and back to the rotational axis 2 when the supporting arm II will turn from the position I la to the radial position' Ilc and from the latter into the position IIb, respectively. I-n addition thereto the sleeve I2 wi-llv be slightly angularly displaced. These two secondary movements may be in most cases disregarded as they will not affect the proper operation: of. the sleeve.

However, in some cases particularly when large sized sleeves or sleeve groups are attached to each supporting arm II the said angular displacement of the sleeve or sleeve group may become disturbing. 'Io avoid this disadvantage my apparatus may be constructed as illustrated in Figs. 4, '5 and 6. This embodiment is. basically identical with the embodiment shown in Figs. 1 and 2 and described above in detail. However, according to Figs. 4 5 the sleeves I2 are not rigidly mounted upon their respective arm II but are journaled thereto by means of a pivot 2B. A supplemental connecting bar 2,3 is journaled with one end at to the driving member Il and with its other end to said sleeveA I2 or to an integral part thereof such as the arm 2i. The said bar 23 will practically completely prevent an angular displacement of the sleeve I2 while the same is otherwise in a stationary position during its operation.

The embodiment shown in Figs. l through 6 maybe modiiedas illustratedA in Figs. 7-8 which show in a top view three succeeding positions of the supporting arm II and the driving member Il while they latter turns about an angle a during the rest period ofthe sleeves I2. In this modiiied embodiment a group of two sleeves I2 is` journaled upon each arm II. It will be well understood that the sleeves I2 may be arranged in other groups than in groups of two and that they may be adapted to receive any kind of material such as cigarettes, tobacco, tea, drugs and other commodities.

While three specific embodiments of my invention have been shown and described in detail to illustrate the application of the principles of my invention, it will be well understood that the same may be otherwise embodied without departing from such principles.
