Description

The invention relates to a conveying device for rod-shaped articles of tobacco processing Industry for transferring products from longitudinal axial conveying in transverse axial Further promotion, comprising a cross conveyor with a running in the transverse conveying direction curved conveying surface, arranged at fixed intervals, the rod-shaped Article receiving transverse views, and with a longitudinal axis promoted rod-shaped article receiving device, the Takeover-Aufnahmepaare includes, in which the cross-sections are divided and the one fixed to the curved conveying surface fixed transverse recording and a along controlled track in the free area above the conveying surface of this have removable movable transverse recording, which at least to take over a rod-shaped article is movable against the transverse conveying direction, wherein a Transfer level is determined, in each case a takeover pair with in their Transfer position brought movable transverse recording the longitudinal axial promoted rod-shaped article takes over, and wherein the controlled path is such that the movable cross-section from their takeover position in their conveying position the transverse conveying surface is returned. Under rod-shaped article of the tobacco processing Industry are especially cigarettes, filter cigarettes, filter rods, cigars and cigarillos made with special manufacturing machines. In particular, the conveying device is a device with a transfer drum, the cigarettes in the form of double-length tobacco sticks from one of these in the direction their length (longitudinally) advancing double strand machine takes over in pairs, to define them on the transfer drum transversely to their extension (cross-axial) in defined To give intervals to the drum of a filter attachment machine. The invention also relates to a transfer element of a transfer conveyor of the conveyor.

According to DE 37 35 006 a generic device is proposed in the movable Dumping levers on a takeover drum to take over cigarettes Swing up against the transverse conveying direction. Every movable trough is at the Drum conveying surface behind a pair of associated fixed trough arranged. It a division reduction of the trough spacing is sought. The devices However, they have not found their way into practice. This is u.a. in operation of the Lever with high swivel frequency, in spatial steering and steering problems as well as in the transverse conveying surface unfavorably flat orientation of the feeding planes of Transfer dumps justified. In particular, it does not succeed, desired large conveying speed to achieve with functionally reliable handover of cigarettes.

From DE 41 29 672 is a device with a transfer conveyor of a double-strand machine known, which transports cigarettes in pairs to a take-over level, at a side vertex of a takeover drum forming a cross conveyor is in a vertical position to Drummelförderfläche. The transfer conveyor instructs advantages in terms of throughput and speed. On the other hand, operation remains and performance of the cross conveyor insufficient. Movable hollows are in the same direction arranged with the drum running up swinging lever arms. These Arrangement leads to disadvantages. Imbalance causes levers, cams, cam rollers and roller lever heavily loaded, the movable troughs on relative steep track to be lifted out of the conveying surface. Opening and closing angle the trough pivot lever are relatively large. A very significant disadvantage exists in that the movable trough at the time of acquisition with considerably larger Path speed is moved as the solid trough of each takeover pair and the holding surface of the movable trough must be sized small so that they with a conveying trough of the transfer conveyor can cooperate. One for safe transfer to be provided overspeed of the transfer troughs the takeover troughs can be due to considerable speed difference between fixed and mobile trough at the crossing point not uniform and not reach the required level. There have to be compromises which are associated with lower performance and risk of instability in the transfer leave. Lead the lever, which swings in the same direction with the conveying direction undesirable to a relation to the trough spacing of the transfer troughs at the Conveying surface larger pitch.

Object of the invention are to provide a conveying device for rod-shaped article of Tobacco processing industry to create, with the high-speed operation, reduction from wear, functional reliability and especially a safe pairwise Article transfer with overspeed equally with respect to fixed and movable takeover recordings are to be achieved. For throughput increase favorable pitch distances should be able to be set up. The transfer conveyor a device according to the invention should be operable at a particularly high speed be, wherein in the longitudinal axial direction in parallel strands conveyed rod-shaped Article on relatively simple paths in a transfer plane of the device should be transferable. Accordingly, transfer elements of the transfer conveyor should easy to build and special for high speed flyover purposes adapted design received.

Objects of the invention are in conjunction with the features of the aforementioned Conveyor achieved in that at the curved transverse conveying surface, the fixed Transverse image of each acquisition-admission pair in cross-conveyor direction behind the associated movable transverse receptacle arranged and the movable transverse receptacle is arranged and movable along its controlled path that they on the path to their takeover position in the takeover plane, viewed in the transverse direction of curvature corresponding arc direction, in to the pair associated fixed cross-section leading positions with up to the fixed cross-section up Zero decreasing arc distance is brought. With the solution according to the invention There are quite a few advantages. Due to the arrangement of the fixed cross-sections behind the movable cross-section included in the takeover pair initially achieved that the movable transverse recording when approaching the Übemahmeebene leading in front of the fixed shot, in connection with a forward movement the moving cross-brakes braking negative acceleration, so that they at least substantially the same speed at the time of takeover like the solid cross-section in the pair. Of very significant importance is that the transfer speed of rod-shaped articles in pairs in longitudinal shots conveyed by transfer elements, with respect to those in the pair corresponding fixed and movable transverse recordings are relatively large can. The transfer overspeed both at the fixed cross-section as also at the movable cross-recording of each takeover pair is advantageous 15% and more. Function reliability and high-speed operation are improved significantly compared with known devices. The order the movable transverse recording in front of the fixed cross-section causes the Movable recording already at a relatively early date from curved transverse conveyor is led out. In particular, excessive acceleration as well Excessive deflection movements and / or angles of the movable cross-sections avoided on their tracks leading parts. Mechanical load and energy input are kept relatively low; it can be relatively large throughput achieve. Furthermore, it is achieved due to the space and Movement arrangement of fixed and movable cross-sections on the transverse conveying surface, that distances of the cross-shots on the transverse conveying surface deliberately less than the distance between two transfer recordings can be provided. each movable cross-section can be formed in the form of a trough, which is particularly large is dimensioned and in particular the same receiving cross-section as the associated has solid transverse recording. This, too, is the handover / takeover process significantly improved. The larger trough surface also has a favorable effect on the vacuum supply from commonly provided suction troughs. As a result of the invention Arrangement of the transverse photographs in connection with the takeover before the fixed cross-shorts leading, braked movable cross-bracing works the device with a transfer plane, which is directed relatively steeply to the conveying surface is. This transfer level allows in a particularly favorable manner to the coupling a high-speed transfer conveyor whose transfer elements the rod-shaped Each article in the appropriate recipient level to the transfer level introduce. It can be seen that the device according to the invention in particular in terms of speed, reduction of mechanical load, kinematic Conditions and spatial-constructive arrangement has significant advantages, the in conjunction with a transfer conveyor, which the rod-shaped article with particularly fast moving transfer elements promotes, are of particular use.

Appropriately, the movable cross-section of each take-up recording pair arranged and guided along its path that they on the way in their takeover position, viewed in a direction perpendicular to the takeover level, in front of the pair of associated fixed transverse receiving leading positions arrives, from which in reducing the lead distance in the vertical viewing direction in their takeover position is moved. With this measure one reaches a particularly pronounced advance of the movable cross-section and thus a particularly strong Braking the same, in particular at particularly high transfer speed at the time of transfer to the same speed with the fixed cross-section bring to.

The movable cross-section can be held by any suitable mechanical means and be led. A particularly convenient and advantageous mechanical design is that each movable cross-recording each part of the im pivoted state holding the movable cross-receiving on the transverse conveying surface Receiving lever is, which, viewed in the transverse conveying direction, behind the pair in the associated Fixed cross-section, preferably in the area between the two cross-shots of the conveyor surface in the transverse conveying direction subsequent pair on a conveyor body moving the transverse conveying surface is articulated, wherein the receiving lever on the way of the movable cross-recording into its transfer position swings up against the transverse conveying direction. Particularly advantageous, the recording lever in the area between two webs with fixed cross-sections in the Be hinged near the rear web in the transverse conveying direction. Combined with the above linkages can take over the takeover lever particularly favorable spatial arrangement and advantageous kinematic conditions appropriate in be articulated to a level below the transverse conveying surface. Especially with the mentioned Embodiments of the articulation of the receiving lever to reach a Transverse conveying surface largely flat position of the pivoted lever, wherein the Length of the effective lever pivot arm, which is quite more than twice as big as the distance between the transverse supports on the transverse conveying surface can be relatively large can be used to move the transversal acquisition into as possible large distance to the cross conveyor surface to bring. In a particularly convenient and preferred Design is the intake lever as an angle arm with a in the area his free end formed the movable cross-section carrying free arm thighs, the at least in positions of approach of the movable transverse receptacle the takeover level and in the position of the acquisition substantially perpendicular is directed to a moving plane in which the associated in the pair fixed cross-section which is parallel to the transfer level or in the transfer position coincides with this.

The conveying device has a rotational body in a preferred design and construction in the form of a rotatably mounted drum body with the transverse conveying surface forming peripheral surface. Particularly advantageous can in such a designed Device, the movable transverse recording of each pair of receptacles arranged such and be guided along its path that the way from leaving the conveying surface to the transfer position in a 90 ° rotation angle range of the rotation body lies. Preferably, the arrangement is provided so that the movable transverse receptacle in the region of the lower vertex of the rotation body, useful in Passing the apex, lifted from the conveying surface and horizontal takeover plane is guided at a side vertex of the rotating body. Achieved with it one particularly long-guided, when leaving the conveying surface opposite this very flat track for the movable cross-section. This leads to particularly low mechanical load of the moving transverse recording leading and holding Parts. The device can be operated at a particularly high speed, whereby also noise development by movement of mechanical parts largely is reduced.

In a particularly advantageous and advantageous design, the inventive Conveyor a transfer conveyor with a plurality of longitudinal shots formed handover intake pairs, in pairs with takeover shots correspond, wherein the arrangement is such that each transfer receptacle on parallel strips received longitudinally conveyed rod-shaped article and under Maintaining a parallel position in the advancing plane in transverse axial direction Direction transported in the transfer plane, the movable cross-recording of each take-up recording pair arranged and guided along its path is that, viewed in the transverse conveying direction, in front of the conveyor plane of the corresponding Transfer pickup pairs leading positions from which they arrive with zero leading distance to their takeover position in the takeover level is moved. The transfer conveyor of the conveyor is special suitable, provided with the provided on the cross conveyor, steep to the cross conveyor surface and particular vertical takeover level to cooperate. In accordance with the invention Arrangement and training ensures that the movable cross-section, considered in the transverse conveying direction, relatively far in front of the assigned transfer longitudinal recording is guided to the movable transverse recording by pronounced braking in the Transfer level to the same location and speed level with the associated to bring solid cross-section. As a result, the transfer recording can with to move to the takeover level at a relatively high speed Ensuring the same takeover overspeed as the takeover level parallel holding level of each transfer-taking pair with respect to the takeover shots.

To the moving cross-sections before the date of acquisition in their previous positions before the takeover take-overs according to the invention particularly adapted transfer elements of the transfer conveyor intended. Each transfer element has a receiving body at least two transfer arms connected by at least one web element, at those in the conveyor plane extending parallel transfer longitudinal recordings are arranged; the receiving body is formed so that along with the longitudinal recordings extending transfer arms between these free spaces for the the premium level leading positions of moving acquisition cross-surveys is provided. Particularly advantageously, the receiving body is U-shaped, its legs forming the U-web connected transfer arms. Suitably, in the U-body extending along the U-extension channel for Intake air formed, wherein the transfer recordings with the channel in connection have standing suction openings and on a U-leg a suction port for the channel and a holding piece for connecting the transfer element with a Transfer conveyor gear forming nozzle is formed. It has been found that with such a trained suction channel and connection sufficient suction forces to hold cigarettes in the shots even with relatively low vacuum can be generated. Compared to conventional transfer elements, the one Having body with an H-shape as for example in DE 41 29 672, the vacuum generation reduced by at least 40% without affecting the suction-holding force become.

An illustrated in Fig. 1 cross conveyor 11 of a conveyor device according to the invention 1 comprises a circular cylindrical body of revolution in the form of a drum body 31 a takeover drum. The peripheral surface of the Z-axis rotatably mounted Drum body 31 is a running in the direction of circle Q curved conveying surface 14th This has arranged at fixed pitch B, parallel to the Z-axis erstrekkende cross-sections 141. It can be seen that at the in the view of FIG. 1 turning left around Trommerkörper 31, the recordings 141 in the range of its upper vertex to its lower vertex equidistant from B and with same surface level to come to rest. These cross-views are with cigarettes 9, in the area in front of the lower drum crest with not shown Drum removed.

The cross conveyor 11 has a transfer device 2. This is through takeover receiving pairs 21 formed, which in turn by a pairwise subdivision of Transverse 141 are formed. On the whole are in the embodiment on the periphery the drum body 31 seventeen takeover recording pairs 21 is provided. each Pick-up pair 21 has a fixed to the transverse conveying surface 14 transverse recording 211 and a movable, namely along controlled path 23 in the free area above the conveying surface 14 from this movable movable transverse receptacle 212.

According to the invention, viewed in the transverse conveying direction Q, the fixed cross-section 211 of each pair of receptacles 21 behind the movable receptacle associated with the pair 212 arranged. Each movable transverse receptacle 212 is in each case part of a receiving lever 22, which, viewed in transverse conveying direction Q, behind that in the pair fixed transverse receptacle 211 about to the drum rotation axis parallel pivot axis 220 is hinged to an end wall of the drum body 31. In the area of downhill Transverse conveying surface 14 are the recording lever 22 in pivoted, to the transverse conveying surface 14 flat position.

The solid transverse receivers 211 are at free ends radially on the peripheral surface of the Drum body 31 protruding drum webs 311 arranged. Each pickup lever 22 is in the area between two radial webs 311 in the vicinity of the transverse conveying direction Q rear web 311 hinged. It can be seen that the effective Swivel arm 221 of each receiving lever 22, whose arm length H the swivel radius determined, in the pivoted state in a largely flat position to the transverse conveying surface 14 extends.

Each movable cross-section 212, the rotation of the drum body in the direction Q passes the lower drum crest, is up along the track 23 in the Area of the drum between the lower drum crest and the following lifted side apex of the conveying surface 14. Everyone is swinging in this way Lever 22 in opposite directions to the conveying direction Q from the conveying surface 14 out. At the lateral vertex passes the movable transverse receptacle 212 of each pair of receptacles 21 into a transfer level 20, which is determined by the fact that in this level in each case the two transverse exposures 211, 212 of each receiving pair 21 for the same time Acceptance of cigarettes 91, 92 of transfer elements 4 one in Fig. 2nd shown transfer conveyor 12 come to rest. Takeover level 20 falls with directed perpendicular to the conveying surface 14 radial plane of the drum body 31 together. The transverse receptacles 211, 212 have a distance in the transfer plane 20 A on, due to the inventive arrangement and articulation of the transverse photographs 211, 212 greater than the pitch B of the transverse receivers 141 at the Conveying surface 14 is. Appropriately, a distance ratio of 12/10 is selected.

When the transverse exposures 211, 212 of each pair of receptacles 21, the horizontal transfer plane Leave at 20 rotating in the direction of the drum body 31, pivots the lever 22 according to the direction of the swivel direction in the same direction with the conveying direction Q in its flat position on the conveying surface 14, in the 90 ° rotation angle range between the transfer plane 20 and the upper vertex of the drum body 31. Die movable receptacle 212 passes advantageous in the upper drum crest again in the Conveying surface 14. The path of the movable transverse support 212 of the closing Lever 22 is slightly shorter than the path of the movable recording 212 between the bottom and side take-over vertices, as further explained becomes.

Each take-up lever 22 has beak-like shape with free lever arm leg 222 on. The arm leg 222 is shaped so that it at least in positions of approach the movable transverse receiver 212 to the transfer plane 20 and in the Position of acquisition steep, in particular substantially perpendicular to a moving away Level EF is directed, in which the pair associated solid transverse receptacle 211st and is in parallel with transfer level 20 or in the transfer position coincides with this. The angled lever 22 is corresponding to the curvature of the Transverse conveying surface 14 convexly curved. In the middle convex curvature area he has a contour 228, which in the pivoted lever state in the level of Transverse conveying surface 14 is located. A pickup head 223 is non-rotatable with the end of the arm leg 222 connected and directed perpendicular to this. The pickup head 223 has a concave neck portion 224 forming the movable transverse receiver 212 on, at the transverse conveying surface 14 and the free end of the receiving lever 22nd opposite side of the receiving head 223 is formed, so that the receiving trough 212 arises with a large acceptance angle of 90 °.

Suitably, the arranged in the area in front of the lower drum crown drum a Abbremstrommel, which takes the cigarettes 9 in troughs whose pitch is smaller than the pitch B of the drum body 31. Even though each fixed cross-section 211 with a trough-receiving angle of 90 ° at the web 311st has a front in the transverse conveying direction Q high shoulder, takes place due to inventive lever design and arrangement the transfer into the Abbremstrommel no caming.

In Fig. 1, the transfer element 4 can be seen in the amount of transfer plane 20, the a transfer pickup pair 41 with outer longitudinal receptacle 411 and inner longitudinal receptacle 412 has. The longitudinal recordings 411, 412 are provided at a pitch, the same as the distance A of the transverse receptacles 211, 212 in the transfer plane 20 is. Each transfer element 4 is viewed from a, in the conveying direction Q before the transfer plane 20 located in Fig. 1 lower position P 1 in the transfer plane 20 vertical Anförderrichtung moved to the upper takeover position.

Each individual receptacle 211, 212, 411 and 412 has a trough with an acceptance angle from 90 ° up. Thus, in the transfer level 20, the fixed cross-section is added 211 and the outer longitudinal receptacle 411 and the movable transverse receptacle 212 and the inner longitudinal receptacle 412, in each case a double receptacle with a 180 ° receiving cross-section. Each double recording is against the vertical direction of conveying open. It can be seen that the cigarettes 91, 92, in the seat in the receptacles 411, 412 be promoted to the acquisition level 20, in Zuförderrichtung in the assigned Takeover cross-sections 211 and 212 are introduced.

According to FIG. 3, the transfer device 2 of FIG. 1 is shown in detail. In the Transverse conveying direction Q before the transfer plane 20 to see solid cross-shot 211st is not for the sake of simplicity of presentation with an already inherited Cigarette occupied. As usual, all recordings on the trough bottom of FIG. 3 apparent suction slots, is applied to the vacuum to the cigarettes 91, 92nd respectively in the recordings or by switching off the suction air from the recordings release. The drum body 31 and the takeover lever 22 are in common equipped with air ducts to the suction slots for simultaneous transfer and take over the cigarettes 91, 92 to operate in accordance with an air control. Such Saugluftaufnahmen and systems for holding and releasing cigarettes are common and will not be described here.

The transfer conveyor 12 of FIG. 2 includes a plurality of elliptical webs circulating transfer elements 4. Such a per se known transfer conveyor picks up cigarettes 9 from horizontal transport plane 13. The cigarettes will be 9 along a rail 130 in parallel paths 131, 132 in the longitudinal axial direction L promotes. In Fig. 1 is to illustrate the arrangement of cross conveyor 11 and Transfer conveyor 12, the transfer element 4 in the lower in Fig. 2 position P1 at the Transport level 13 shown. Each transfer element 4 is by means of a nozzle piece 46 with a transmission, not shown, on a housing 47 of the transfer conveyor 12 connected.

An inventive transfer element 4 is shown in FIGS. 5A to 6B. It points a U-shaped body 43. The U-legs are connected by U-web 45 Parallel transfer arms 44. Along one arm 44, the outer transfer longitudinal receptacle is along the same 411 and on the other arm 44 in the same way the inner Transfer longitudinal receptacle 412 formed. The longitudinal recordings 411, 412 extend itself in a plane which is defined as the feed-in level 40 of the transfer element 4. The elliptical guide of each transfer element 4 is such that it in Fig. 2 from the Position P1 is raised via an intermediate position P2 in the position P3, the in Fig. 1 illustrated position corresponds to the transfer plane 20. One recognizes that the feeding level 40 of each element 4 in a horizontal and thus parallel position to the longitudinal transport plane 13 remains. The high-speed double-stranded cigarettes 9 are transported from the flat curved part in the strongly curved Part of the elliptical orbit transferred. That way is one High-speed conversion of the cigarettes 9 conveyed in the longitudinal direction L. in the cross-axial direction Y reached.

As already described, it is essential that the cigarettes 91, 92 in the Transfer level 20 from the transfer-receiving pair 41 reliably and optimally the take-over take-up pair 21 is delivered. This succeeds due to the invention Arrangement and design of the recording lever 22 in conjunction with their counter to the conveying direction Q movements in the direction of pivoting S. As in particular As can be seen in Fig. 1, the movable transverse receiver 212 of each Takeover pair 21 on the way to their takeover position, considered in to the circular arc conveying direction Q corresponding direction, in to that in the pair 21 associated fixed cross-section 211 leading positions with to the fixed cross-section 211 brought down to zero decreasing arc distance.

In Fig. 1 are on the way from the lower drum crest to the side drum crest shown four positions, by which it can be seen that the arc distance B1, B2, B3 and B4 becomes progressively smaller. This is accompanied by the fact that the movable Recording 212 of each receiving lever 22 on its way to the transfer plane 20 to a considerable extent in front of the feed plane 40 of each hurrying transfer element 4 leading positions is brought. This is based on FIGS. 4A and 4B 4B shown in more detail. Fig. 4A shows a position in which the movable cross-recording 212 in direction Y perpendicular to the transfer plane 20 with the path V in front of the intake plane 40 leads. As a result of the opposite direction to the conveying direction Q superimposed Lever arm movement S, the movement of the movable transverse receptacle 212 is targeted braked so strongly that at the time in Fig. 4B, in which the conveyor plane 40 in the takeover level reaches 20, the speeds of the two cross-shots 211 and 212 are equal in relation to the speed of the conveyor plane 40, between the two transverse recordings 211 and 212 so no difference in speed consists. It is achieved by the fact that in the acquisition level 20 of the transfer longitudinal recordings 411, 412 dispensed cigarettes 91, 92 alike with considerable Overspeed to the transversely receiving them 211 and 212 be delivered. For this purpose, the speed of the feed plane 40 at the point of takeover level 20 considerably larger than the same occurring there Web speed of the two cross-shots 211, 212, expedient with 15% and more chosen.

A particular measure is that the receiving lever 22 when approaching is pivoted to the receiving plane 20 such that the movable transverse recording 212 in the direction parallel to the Y direction, i. in vertical plane to transfer 20 Direction in front of the fixed cross-section 211 of the associated pair leading Position is brought. Such a movement situation can be seen in FIG. 4A. The movable cross-section 212 is located at a distance Y3 before a moving away Plane EF, in which the pair in the associated fixed transverse receptacle 211 and the parallel with the takeover level is 20. Characterized in that the movable transverse receptacle 212 the associated fixed receptacle 211 overtaken in Y-direction before passing through deceleration brought into their takeover position in takeover level 20, can be Speeds of the two receptacles 211, 212 of a pair 21 at the time of Assumption with respect to the approaching transfer element 4 in particular at reliably match relatively high conveying speed, and although at the lowest possible mechanical load of the lever 22 controlling curves and roles. The drum body 31 can easily be rotated 650 rpm and more are operated. Due to inventive arrangement and linkage of the lever 22 remains its opening angle from the beginning of the opening at the bottom Drum apex to the maximum takeover opening position at an angle of less than 40 ° relatively low.

The position of a dash-dotted in Fig. 5B shown receiving lever 22 with recording 212 corresponds approximately to the position shown in Fig. 4A. With this position Corresponds also one in Fig. 6A at a slightly later time in plan view shown position, while the top view in Fig. 6B, the situation at the Übemahmeebene 20 represents. It can be seen that each transfer element 4 on its elliptical Path in Fig. 2 in the direction parallel to the direction L and to the coordinate direction Z is moved to the lever 22. As can be seen in particular from FIGS. 1, 3, 4A, 4B and 5B, It must be ensured that the recording head 212 having the transverse receptacle 223 laterally and from above in the pivoting direction S, that is from leading Immerse position in the area between the transfer arms 44 of the transfer element 4 can. By interconnected with U-web 45 transfer arms 44 the free space 42 required for the movement positions of the pickup head 223 reached. The open U-side of the U-body 43 faces the free lever arm leg 222. Since the lever pickup head 223 not only from above but also from the Side passes between the transfer arms 44, it comes in accordance with non-illustrated embodiment for example, also considered, the U-web 45 by a in the conveying direction over the two arms 44 to replace extending web element under a Such a bridge between the arms 44 and above the same sufficiently free Room left.

Each transfer member 4 is known per se with air intake openings for holding the cigarettes 91, 92 in troughs of the receptacles 411, 412 equipped. In the U-body 43 of the transfer element 4 shown in FIGS. 5 and 6 is along the U-extension extending channel formed for intake air in the receiving wells with suction slots is open. The center of the one arm 43 provided piece piece 46 forms both the suction port for the channel and the holding piece for connecting to the transmission of the transfer conveyor 12th

As can be seen from Fig. 1, the Aufschwenkweg of each receiving lever 22 is so provided that each movable cross-section 212 immediately after passing through the bottom vertex of the drum body 31 when leaving the peripheral conveying surface fourteenth first comes in positions that are in the Y direction behind that in the pair 21 associated remain fixed slidably 211 with distances Y1 and Y2 decreasing. you achieved by virtue of the fact that each movable cross-section 212 can be moved as early as possible, between the lower apex and the lateral apex of the drum body 31 relatively long track and relatively flat and thus steadily from the cross conveyor 14 appears and is led over this.

In the embodiment of FIG. 1, the pivoting and closing angle of a each receiving lever 22 by means of a relative to the rotating drum body 31 stationary cam groove 321 controlled. As can be seen from Figs. 7A and 7B, each is Recording lever 22 by means of a pivot shaft 225 on an end wall of the Drum body 31 pivotally mounted about the pivot axis 220. With an end the shaft 225 is passed through the wall of the drum body 31 and there with a roller 227 having a roller 226 connected. The curve groove 321 is formed in a flange 32, which on a stationary, not shown Drum body 31 rotatably supporting part is fixed.

From Fig. 7B it can be seen that the stationary cam groove 321 in the region of the pivoted Levers 22 has circular course. A deviating from the circuit Curve portion of the groove 321, the lever roller 227 on the opposite Circle path leads shorter path, controls the swinging and swinging back of the lever 22. The pivoting of the lever 22 controlling part of the way gives way to a greater extent from the course of the circle than the swinging back controlling Away part. This achieves that the movable cross-section 212 already at the bottom Drum apex steadily and flat lifts off the transverse conveyor surface, with the above-described first remaining in the Y direction positions 41, 42, while after passing the takeover level 20 on towards the path of admission 212 of the pivoting lever 22 a little shorter way into the transverse conveying surface 14 is returned.
