PROMOTION UNIT
The invention concerns a promotion unit for filling a machine, in particular a machine to packing cigarettes in with a hinged flap provided packages, with sheet material, in particular with preformed or punched pieces from cardboard od.dgl., with which to the installation between the machine and a Sammellager for the preformed are intended pieces of two an angle of essentially 900 screen end Fördereinriohtungen with one another, whose everyone exhibits Trägerund sliding surface, along which the preformed pieces are gradually movable, whereby at the outgoing station a conveyer system the preformed pieces are ignorable to the entrance station of the second conveyer system.
In the IT-PS No. 992092 a packaging machine is become known to a column-like container is supplied, whose lower end is arranged, which can be connected with a BeI0 schickungsund collecting mechanism, with which preformed pieces continuously above an entrance station of a first conveyer system, whose outgoing station is connected with an entrance station of a second conveyer system, which forms the inlet element for the packaging machine and which under an angle from 90° to the first conveyer system angel5 arranges is.
In a promotion unit to the Beschiekung of a periodically working packaging machine, which to each other exhibits two conveyer systems arranged in an angle of 90°, handing the preformed pieces of the first conveyer system over prepares many technical problems on the second conveyer system. Handing the preformed pieces of a conveyer system over must take place on the other one in extremely precise way and with extremely close position tolerances. Therefore must the preformed pieces with it of first Übertragungselementen translating on the second conveyer system always exactly interactions, and the situation taken by the preformed pieces when putting on on the second conveyer system must be likewise very exact.
The construction of a promotion unit, which fulfills these demands with relatively low working frequencies, represents generally no problem. However if the working frequency exceeds a certain value, then enormous problems, above all then, develop if the demanded working frequency is very high, e.g. if a periodically working packaging machine be fed must, which runs with a working frequency in the order of magnitude from 7 or more steps per second.
The forces of inertia affecting at such speeds the preformed pieces are so large that not only the preformed pieces must be carried and led during handing over from a Fördereinriohtung to other continuously, but also the mobile Übertragungse] emente must in their number small and from simple structure be, so that they can be easily propelled and auoh no very much complicated Steuereinriohtung to require, which would reduce the operating they agoness of the promotion unit considerably.
Task of the invention is it to avoid the disadvantages of the well-known Einriohtungen.
This task is solved according to invention by the fact that Trägerund sliding surface of the second conveyer system on a higher level is arranged than those the first Fördereinriohtung that to the Nacheinanderanheben of the preformed pieces on the level Trägerund sliding surface of the second conveyer system one is intended by Trägerund sliding surface at the outgoing station of the first Fördereinriohtung aufund abbewegbare raising unit that for holding the preformed pieces in the raised position a carrier unit is arranged above the outgoing station mobile, and that above the outgoing station of the first conveyer system and for the entrance station of the second Fördereinriohtung and is intended by this away movable and laterally impact unit bringable with everyone of the preformed pieces in the raised position in the interference.
Further favourable arrangements of the invention are to be inferred from the Unteransprüchen.
Further characteristics and advantages of the invention are on the basis the designs, which represent a remark example, more near described and are described.

The Fig.1 shows a Förderelnheit, the two conveyer systems --1 and 2-- it exhibits which with one another form S an angle of 90° and are so arranged that them preformed pieces --3-- supply a not represented, periodically working machine to packing cigarettes into packages provided with a hinged flap.
In the conveyer system in detail descriptive for the state of the art not counting DE-OS 2718954 --1-- becomes in an essentially horizontal situation of a basic frame --4-- carried and runs between one in detail in not the entrance station descriptive for the state of the art counting DE-OS 2718842 --5-- and an outgoing station --6--, at that the preformed pieces -- -- on a second conveyer system --2-- crossed and/or.
are transferred. In a place along the conveyer system --1-- is in detail the folding station 15 descriptive for the state of the art not counting DE-OS Z718953--7--, the one latch, which one of the ends of the preformed pieces forms, to fold can.
The conveyer system --1-- Trägerund running in longitudinal direction possesses guiing device --8--, which in an essentially horizontal situation above the basic frame --4-- arranged and which at both ends with two blocks --9-- (of those only one in the Fig.l is shown) provided is horizontal, the two and transverse to the longitudinal axis of the Führungs2C of element --8-- arranged waves --10 and 11-- carry. At the two ends of the wave --10-- are two pinions --12-- swivelling attached, of those everyone together with an appropriate, on the wave --11-- festgekeilten pinion --1 -- two endless, parallel to the longitudinal axis of the guiing device --8-- running volumes --14 and/or 15-- carries and with these in the interference stands.
Two even lateral plates --16 and 17--, along in longitudinal direction up-end themselves guiing device --8-- extend, are fastened to this and protrude laterally from it in opposite, crosswise running directions.
A middle bar running in longitudinal direction --18-- is with the guiing device --8-- connected and one possesses with the upper even surface of the plates --16 and 17-- in same level lying upper surface, which with these two surfaces of the plates --16 and 17-- Trägerund sliding surface for the preformed pieces --3-- forms. Each preformed piece --3-- becomes in each case one by two above the bar --18-- crosswise running and with their ends over guidance shoes --20-- with the volumes --14 and 15-- connected bolts --19-- formed promotion compartment supplied and therein carries. Each shoe --20-- possesses laterally an even surface, those in contact with a lateral even surface of the bar --18-- , and an essentially rectangular formation, in an appropriate lateral is located groove running in longitudinal direction --21-- in the bar --18-- sliding intervenes.
The situation of the preformed pieces --3-- in transverse direction in the respective promotion compartments becomes on a side of a Pührungsschulter --22--, those with the upper surface of the plate 40--16-- is connected, and on the other side of a guidance shoulder --23--, those with the upper surface of the plate --17-- connected, steered. The guidance shoulder --22-- runs in longitudinal direction along the entire plate --16--, while the guidance shoulder --23-- at least partly within the range of the stations --5, 6 and 7-- is interrupted. In particular at the station --5-- is the shoulder --23-- of a tax backdrop --24-- replaced, those on one of the 5 plate --17-- carried taps --25-- is swivelling installed. In order to prevent that the preformed pieces vertically of the plates --16 and 17-- and the bar --18-- fall down, are with the shoulder --23-- above the plate --17-- protruding arms --26-- connected, which a vertical, over between the stations --5 and 7-- lying range of the conveyer system --i-- running guidance measurer --27-- carry. As represented in Fig.2, is in the basic frame 50--4-- in transverse direction their movement of a Antriebselnheit (not represented) deriving drive shaft --28-- attached, on the one cone gear wheel --29-- is festgekeilt, which with a cone gear wheel --30-- in interference, that stands on the end of one in longitudinal direction along the basic frame --4-- running wave --31-- is festgekeilt, which as PTO drive for one at the entrance station --5-- attached Betätigungsund control unit (not represented) works.
On the drive shaft --28-- is a cylindrical pinion --32-- aufgekeilt, which is so arranged that it a movement in the following the descriptive way on a drive unit for the gradual drive of the volumes --14 and 15-- transfers.
The pinion --32-- turns over a pinion --33--, its axle parallel to the drive shaft --28-- , a well-known driving device runs --34--, those with loose roles and arc-shaped sectors parallel to the periodic or gradual drive on an end to the drive shaft --28-- running wave --36-- installed Geneva disk --35-- is provided.
On the second end of the wave --36-- iöt a pinion --37-- festgekeilt, which its periodiI0 sche turn over a pinion --38-- to the wave --11-- and therefore to the pinions --1 -- transfers.
The pinion --32-- shifted likewise on an end parallel to the wave --28-- arranged wave --40-- installed pinion --39-- in turn. The second end of the wave --40-- is rigid with one outside of the basic frame --4-- handwheel present --41-- for the manual adjustment of the entire operating control unit fastens. The drive shaft --28-- it is in such a way arranged that it both the volumes --14 and 15-- and a 0bersetzungseinheit propels, those to the Ausgangsstatian --6-- is arranged and the preformed pieces of the conveyer system --i-- on the conveyer system --2-- translated. This latter (S. Fig.1) runs within a box housing and possesses an entrance station, those from two horizontal one above the other arranged waves --42-- is formed, which with one another by pinions --43-- and radially in contact present with one another supply drums are connected and/or.
Spools --44-- exhibit. Between the waves --42-- run two pairs to each other pointing, vertical measurer --45 and 46--, those between itself a sliding slot for the preformed pieces --3-- form. The lower measurers of these pairs extend above the Ffihrungsschulter --22-- and Trägerund forms sliding surface for the preformed pieces --3-- along the conveyer system --2--, whereby itself this surface on a higher level than Trägerund sliding surface for the preformed pieces --3-- along the conveyer system --1-- finds.
The upper measurers extend within the outgoing station --6-- above the plate --16-- and the bar --18--.
Übertragungsbzw. Translation unit possesses a raising unit --47-- (Fig.2) to the raising of the preformed pieces --3-- against the upper measurers of the pairs of measurers --45 and 46--, as soon as these pieces continue at the outgoing station, a carrier unit --48--to hold, around the preformed pieces in the raised position and a lateral Einlaßführung for the conveyer system --2-- to form, and an impact unit --49--, which is so arranged that her with the preformed pieces --3-- in the raised position co-operates, around it in by the pairs of measurers --45 and 46-- formed slot and between the spools --44-- to press. The raising unit --47-- covers a vertical tubular bar --50--, those above with a tubular link --51-- , that is connected by in the plate --16-- intended hole runs, and a second vertical tubular bar --52--, those by in the plate 0--17-- arranged hole runs. The tubular bar --56--, those at their top side with a horizontal, a hole exhibiting plate --53-- , and the tubular bar is provided --52-- are by lines (not represented) with an exhaust distributor mechanism, likewise not represented, connected, which of at an end the wave --28-- eccentric taps present --86-- are steered.
The tubular link --51-- runs by in the bar --18-- intended hole and ends at its top side in one with the upper surface of the plate --53-- in same level lying Sauger --54--.
The bar --52-- with its upper end a connected possesses, parallel to the promotion direction of the conveyer system --I-- arranged vertical plate --55-- with three upper teeth arranged in the same distance --56-- with a hole at the middle tooth. The free end of these teeth --56-- is even and is in same level with the plate --53--, over with this a latter even Anhebefläohe for the preformed pieces --3-- to form. The bars --50 and 52-- run of one swivelling with an end of a tie bar --58-- connected lateral ripple --57-- out upward, whereby the other end of the tie bar at a crank --59-- is linked. The latter is on a lateral ripple --60-- festgekeilt, which on the basic frame --4-- swivelling stored and with a second crank --61-- is provided, which a cam following role --62-- , what latter carries into a groove --63-- in on the drive shaft --28-- festgekeilten cam disk --64-- intervenes.
The carrier unit --48-- covers two claws --65 and 66-- with L-form, those course-turns each other at the station --6-- above the plates --16 and 17-- and the bar --18-- arranged and in each case with horizontal, at the basic frame --4-- swivelling stored lateral ripples --67 and 88-- are connected.
At an end of the lateral ripples --67 and 68-- are two with teeth provided and in the mutual interference standing sectors --69 and 70-- festgekeilt, of those the sector --69-- an eccentric tap --71-- exhibits, which the camp for a tie bar --72-- forms.
An end a latter becomes from a fork --73-- formed, which forms one right-angled axially for IS running recess, in the one shoe --74-- is assigned, which draws from the continuously turning drive shaft --28-- , on that likewise a cam disk is carried --75-- is festgekeilt.
A loose, of the tie bar --72-- carried role --77-- runs in the slots --76-- in the cam disk --75--.
The impact unit --49-- a horizontal, crosswise running bar possesses --78--, those axially essentially slides and with the longitudinal axis of the conveyer system --2-- swore.
With the end of the bar --78-- is in perpendicular direction hiezu and the conveyer system --2-- course-turns a kammförmige plate --79-- connected, those down two teeth --80-- it possesses which are so arranged that them between the teeth --56-- travel through. The other end of the bar --78-- is over the tie bar --81-- with an end of a Schwingarmes --82-- connected, that around a horizontal axle perpendicularly to the bar --78-- and at its an end with a cam disk following role is swivelling --88-- is connected, which in a groove --84--, at the extent and/or on the extent surface of one on the wave --28-- festgekeilten drum-like cam disk --85-- is intended.
The transmission and/or translating of a preformed piece --3-- of the conveyer system --I-- on the Yörd8reinrichtung --2-- in the following with reference to the operation flowcharts in accordance with Yig.3 one describes.
These diagrams refer to a duty cycle of the Fördereinriohtung --I--, which begins in the moment, in that one of the loose roles of the driving device --34-- with the Geneva disk --35-- into interference comes, in order to rotate the latter, i.e. oment in the I, in that the volumes --14 and 15-- after step forward begin, as its result a preformed piece --3-- to the outgoing station --6-- on the plate --53-- by the Sauger --54-- and the teeth --56-- one brings. For simplification however the translation process is described, which begins in the moment, in that the volumes --14 and 15-- continue, after it a preformed piece --3-- to the outgoing station --6-- transported. In the moment, if the volumes --14 and 15-- continue, are the plates --53--, the Sauger --54-- and the plates --55-- at height Trägerund sliding surface of the conveyer system --l-- under the preformed piece --3-- in peace. The latter is both from the plates --58 and 55-- and of the Sauger --54-- held, if these already of the distributor with the suction source (not represented) by means of the eccentric tap --86-- are connected. The same time the kammförmige plate becomes --79-- into their withdrawn rest position brought, i.e. by the entrance station of the Fördereinr [chtung --2-- furthest far away shifts, while the claws --65 and 68-- into the closed position above the station --6-- are spent.
On the descriptive moment following the continuous turn of the wave ensures that itself the bars --50 and 52-- by means of the cam disk --84-- move upward, whereby they ensure that itself above the plate --53--, the Sauger --54-- and the plate --55-- arranged preformed stick --3-- after evenly moves. At the same time the turn of the cam disk produces --75--, those at the same time of the wave --28-- , a movement of the tie bar is propelled --72-- downward and open an appropriate the claws --65 and 66--, so that itself the preformed piece --3-- by the raising unit --47-- moved upward can.
During continuation the bars bring their movement upward --50 and 52-- the preformed piece --3-- between the claws --65 and 66-- in contact with a back support surface, those of the upper measurers of the pairs of measurers --45, 46-- the conveyer system --2-- is formed, and run then again back downward. At the same time the distributor mechanism closes the connection to the suction source, and the tie bar --72-- becomes from the cam disk --75-- upward pressed, around the claws --65 and 66-- on the preformed piece --3-- to close. The further Herunterlaufen of the bars --50 and 52-- the preformed piece on the claws lets --65 and 66-- back, which hold it in a situation, in that it exactly with the Fördereinrichtnng --2-- on a level swore, which with of the lower measurers of the pairs of measurers --45 and 46-- formed Trägerund Gleitflä¢he on one level lies. To this point one should note that the claws --65 and 66-- for it are not only necessary, the preformed piece --3-- into the precise situation to the entering the conveyer system --2-- to induce, but likewise to it, the bars --56 and 52-- to be able to move immediately downward and the plate --53--, the Sauger --54-- and the plate --55-- under Trägerund sliding surface of the conveyer system --i-- bring to be able, with it they not with the bolt --19-- the next promotion compartment collide, which for station --6-- due to the following forward movement of the conveyer system --l-- one carries.
If the preformed piece --3-- between the claws --65 and 66-- , becomes the kammförmige plate is left --79--, those up to this time of the cam disk --85-- in its withdrawn position held is, now forward by the latters against the raised preformed piece --3-- moved, around this between the spools --44-- the conveyer system --2-- to press.
The kammförmige plate --79-- now on such a height and/or on such a level it is brought that it partly up and partly underneath the raised preformed piece --S-- runs, in order to secure so an inevitable interference with lateral these zugekehrtcn the edge of the preformed piece.
It should be held in the view on that this interference between the preformed piece --S-- and the plate --79-- one of the substantial characteristics of the descriptive promotion unit represents and one of the fundamental reasons forms, why Trägerund sliding surfaces of the two conveyer systems --i and 2-- on different level, whereby this characteristic makes it necessary, the raising unit is arranged --47-- and the carrier unit --48-- to use.
It should be held likewise that the teeth --56-- and the teeth --80-- it is necessary, in order to prevent that the two vertical plates --55 and 79-- during the processing step of the bar --78-- collide with one another. Because of the high working frequency of the conveyer system --1-- the plate must --79-- to be moved forward, as soon as the plate --55-- the preformed piece in the claws --65 and 66-- leaves.
The reversal of the plate --79-- in their withdrawn position and/or situation essentially falls with the stopping of a new preformed piece --3-- on the station --5-- and with the beginning of a new duty cycle similar to described the above together. A conveying unit for feeding preshaped pieces of cardboard to a machine for packaging cigarettes into hinged lid packets, the unit including a first and a second conveyor arranged substantially at right angles to one another and along each of which said pieces are advanced in contact with a support surface, the second of said support surfaces being arranged at a higher level than the first, and a transfer mechanism being provided to raise said pieces one by one from said first surface, support each raised piece in said raised position, and then push the same on to said second surface. i.
