Definitions
- the invention relates to an inserting machine and a loading method, by means of which products are placed in open top, mostly trough-shaped, trays and these trays are then sealed tightly by a sealed on the edge sealing film.
- this object is achieved by the receiving tray is moved along with the product in the passage direction with the product during the discharge of the products from the product conveyor via its preferably fixed discharge edge, preferably at the same speed, which has the discarded product at the time of discharge - thereby the relative speed be reduced to zero in the direction of flow between product and tray, so that the most pliable product on the ground of the tray lands without being deformed or corrugated there by a relative speed.
- the product to be thrown off or the portion of several products can also be thrown off at a very high speed, in particular more than 300 mm / s, over the discharge edge, which results in a high insertion rate and thus high efficiency of a corresponding insertion machine.
- the edge of the tray is therefore covered by a mask arranged above it during the ejection, which prevents the impact of liquid droplets.
- the mask is located at such a small distance above the edge of the tray or is even on this that penetration of liquid droplets in between is not possible.
- the mask covers the entire edge of the tray.
- the mask covering it is also moved with the tray.
- the mask- which likewise generally lies horizontally like the tray-has a passage opening, in particular, only slightly smaller than the upper opening of the tray. From the edges of this passage opening extending circumferentially walls down. When positioning the mask over the tray these walls protrude into the recess of the tray and can be formed so long in height that they contact the bottom of the tray with its lower edge, in particular an absorbent layer lying there.
- the encircling walls have an outer circumference such that they can barely be inserted into the recess of the tray, whereby preferably the walls of the tray, which are generally tapered slightly conically, are used for centering or, in contrast, the walls of the mask In the state inserted in the tray, maintain a distance to the walls of the tray at all points, albeit as small as possible, so that no dirt adhering to the walls of the tray can adhere to the outer sides of the circumferential wall of the mask.
- the mask is lowered before the drop in the tray into it, moved during the drop along with the tray in the feed direction and moved after stopping the filing of the product in the tray back up out of the tray and against the feed direction to the starting position moved back.
- the mask is moved back and forth at the same height in the feed direction, while the vertical relative movement is performed by the tray, which preferably rests on a liftable and lowerable lifting device.
- the movement in the direction of passage can also be effected by means of the mask by the form-fitting immersed in the tray mask performs the movement in the feed direction and thereby takes the tray.
- the product In order for the product to be thrown off or the portion to be thrown on the product conveyor to be conveyed in the correct rotational position about the vertical axis and at the correct transverse position on the product conveyor, they are positioned before the ejection with respect to the transverse position and preferably also with respect to the rotational position Aligned high axis, for which several methods are available :.
- the cross slides can be firmly positioned and thus not run along with the product on the product conveyor - because the transverse positioning should preferably be done with all described possibilities of lateral positioning with the product conveyor running, not to reduce the efficiency of the insertion machine - or a vertical axis, which remote from the contact surface of the cross slide to the product to be pivoted and thereby be limited to be movable with the product, in which case preferably the contact surface viewed in the plan view is convexly curved.
- Another possibility is to arrange on both sides just above the product conveyor an approximately plate-shaped pivoting segment pivotable about an upright axis, whose upright narrow side is convexly curved, in such a way that when pivoting about the upright axis in the direction this upright narrow side, the contact surface towards the product, always protruding in the direction of the longitudinal center of the product conveyor. By pivoting in the direction of travel while the product is between the two pivoting segments, the product is thus displaced in the direction of the longitudinal center of the product conveyor.
- Another possibility is to detect the transverse position of the product on the product conveyor only by a sensor, but not to prevent, but instead adjust the transverse position of the mask and / or tray at the discharge point to the transverse position of the product.
- the object is thus achieved in that initially a product conveyor is present, the individual products or products assembled to portions transported in the direction of flow and about its front end in the direction of flow, the discharge edge, which is preferably formed fixed passage direction.
- the respective tray in which the at least one product is to be deposited which is dropped over the discharge edge, moves below the discharge edge in the direction of passage with the horizontal speed of the discarded product, so When the product strikes the bottom of the tray, if possible, there is no horizontal relative velocity between the tray and the product.
- This movement of the tray can be effected by means of a tray conveyor, which then preferably extends in the direction of travel from a point in front of the discharge edge to a point after the discharge edge.
- this movement of the tray is caused when dropped by the mask immersed in the tray is moved horizontally in the direction of passage by means of a mask conveyor and thereby entrains the tray, which does not fly at the beginning of this movement on a Trayiliaer, but still on the Supporting plate of a lifting device, which can raise the tray to the mask, so that the tray conveyor begins in the direction of movement behind the discharge edge, but preferably extends into the range of movement of the mask conveyor.
- the apparatus further includes a controller that can control the tray relative to the product conveyor so that the tray is moved just below the product dropped by the discharge edge so that the product ultimately lies on the bottom of the tray.
- the tray can also be positioned in its initial position by being centered in its initial position by immersing the mask, which is in a fixed starting position.
- a pusher is also provided to reciprocate the support plate of the lifting device on which the tray is to rest between a pickup position in which it is loaded with a new tray and a picking position for picking up products in the transverse direction.
- the pusher is preferably part of the lifting device or vice versa.
- a movable in the direction of travel mask with a rim for covering the edge of the tray is present, which should be positioned when the product is dropped over the tray and moved with this.
- This mask has a passage opening through which the at least one product can fall from top to bottom in the tray.
- the edge of the mask, which extends around the passage opening, is dimensioned such that, viewed in the top view, it can cover the upper peripheral edge of the tray, in particular it can completely cover it.
- a relative vertical movement between the mask and tray is necessary, which is caused by a lifting device, which preferably raises the respective tray to the mask and preferably after lowering the products of the mask down to the tray is again out of engagement with the mask.
- the mask itself is preferably only moved horizontally forward and backward and is not subject to any vertical movement, above all because in the opposite case, ie in a vertical movement of the mask, the vertical distance between the tray equipped with the mask and the discharge position, So the product conveyor, would be larger, which would be detrimental for the purposeful storage of the products in the tray.
- the mask itself can also be used, which dips positively into the tray.
- a tray conveyor which moves the respective tray horizontally during the ejection with the product
- the mask itself can also be used, which dips positively into the tray.
- the wet products passing through the mask will leave drops of liquid on the mask, whether on the upper edge or on the inside of the downwardly facing walls of the mask. These drops of liquid will flow down the walls and eventually drip down from the bottom edge of the wall.
- either the mask is dimensioned with its walls so that the walls when immersed in the tray, the interior of which is usually conically sih upward, touching the insides of the walls of the tray and thereby adhering to the walls of the mask liquid removed from the tray.
- Another or alternative alternative is that the bottom of the trays is covered with a suction material that absorbs liquid, and the downwardly projecting walls of the mask are formed so long that when immersing the mask in the tray, the lower edge of the walls the mask sits on the absorbent material of the floor and thereby existing liquid drops are absorbed by the absorbent material.
- the falling through of the products through the through hole is as simple as possible, this should be designed as large as possible.
- the limitation lies in the fact that the walls running around the passage opening still have to fit into the recess of the tray.
- a first solution is to dimension the passage opening and thus the outer circumference of the walls of the mask so large that when they are inserted into the tray, the walls thereof-which surround the conically tapering interior space-contact and the tray is used for centering ,
- the mask is lowered accurately from above into the tray, however, even while moving with the tray, the walls of the mask always keep a small distance to the walls of the tray, which, however, reduces the passage opening through the mask naturally.
- the mask as a tray conveyor, but then the trays on the one hand and the mask on the other hand have to be moved synchronously separately via a conveyor.
- FIGS. 1a and 2a The structure of the machine is best left by the FIGS. 1a and 2a of course, beyond that, of course, the view of FIG. 1b from below as well as the front view of the FIG. 2b and the supervision of Figure 2c :
- the transverse direction 11 is perpendicular to the passage direction 10 of the products, that is to say the conveying direction of the product conveyors 7, 7 ' , 7 " and of the tray conveyor 8.
- the product 1 b is pushed to the correct transverse position and aligned with respect to its rotational position about the vertical axis, ie especially for portions whose side edges are not aligned parallel to the direction of passage 10 .
- This last product conveyor 7 has in its end an obliquely downwardly facing course of the upper strand of this endlessly circulating product conveyor 7, which is a deflection roller with a very small diameter is deflected for the purpose of forming a discharge edge 7a as the end of this product conveyor .
- a product 1 a which is transported on the preferably at constant speed, at least during the ejection process running product conveyor 7 , runs at the end in the oblique area already obliquely down and continues due to its speed, this direction even after overflowing the discharge edge 7 a in free fall and should fall into an underlying Tray 2 , as in the following with reference to the FIGS. 5a, b is explained.
- Such a tray 2 is only in FIG. 2a located, and rests on the support plate 24 of a lifting device 9 which is capable of the support plate 24 from the in FIG. 2 lift shown lowered position until the mounted at a fixed height mask 4 dips with its walls in the tray 2 and its laterally encircling edge 2 a covers, if the tray 2 was previously just below the mask 4 .
- the support plate 24 can be moved away from the machine housing in a transverse position and longitudinal position exactly below the mask 4 , located in the FIGS. 1a . b and 2a . b is in the starting position for performing a discharge operation.
- the mask 4 can from this starting position in the direction of passage 10 by means of a mask conveyor 26 are moved horizontally with the over the discharge edge 7 a flying product 1 c, wherein the mask entrains the tray 2 in this direction because of the immersed in the tray 2 position.
- the mask 4 move with tray 2 preferably at the same speed in the direction of passage 10 as the on the discharge edge 7 a straight dropped product 1 c.
- the tray 2 is filled with a single dropping operation, with which a single product 1 c or a whole portion is dropped into the tray 2 , then the filled tray is lowered down until it disengages from the mask 4 , and via a first Trayor 8 and, if necessary. Another Trayfurer 8 'of the filled Tray 2 removed.
- the lowering of the tray 2 can also take place by means of a vertical movement of the right end portion of the tray conveyor 8 , if the tray 2 is then already on this.
- FIG. 3 shows one opposite the FIGS. 1 a , b and 2 a, b, c to the left extended insertion machine, which is shown without products and trays, but on which it can be seen that by means of the product conveyor 8, the filled trays are transported to a doubling in the direction of passage 10 sealing station 27 , in which is sealed from above a ring around the upper opening 13 of the tray sealing film 3 , to close the filled tray 2 tight, as better understood FIG. 5e to recognize.
- the individual conveyors are mounted, located in the front view in the left part of the controller 50 with the display 50 a and a control unit 50 b and preferably also the whole machine with electrical power supply cabinet ,
- the tray 2 is generally rectangular, and has one around its upper opening 13 all-round, horizontally outwardly projecting edge 2 a, obliquely downwardly inwardly extending walls and a bottom 2 b, on which a suction material 14 lie which can absorb liquid such as meat juice well.
- the mask 4 has a continuous from top to bottom through opening 12, which is slightly smaller than the opening 13 of the tray 2.
- the through hole 12 of the mask 4 is also generally rectangular, from which also usually obliquely from top to bottom extend to the center inclined individual walls 4 b or a single ring extending around the passage opening 12 wall.
- the passage opening 12 of the mask 4 is also surrounded by a horizontally outwardly projecting edge 4 a.
- the dimensioning of the mask 4 is adapted to the tray 2 such that - as in FIG. 5b represented by subsequent lifting of the tray 2 by means of a lifting device 9 of the tray 2 can be raised so far that the walls 4 b of the mask 4 dip into the opening 13 of the tray 2 and possibly also reach the bottom and the absorbent material 14 - or if such a suction material does not exist, the bottom of the tray - can contact if the walls of the mask are sufficiently high, which is not always the case.
- the contact causes a possibly at the lower edge of the peripheral wall 4b of the mask 4 forming liquid droplets 6 does not drop at any time, but targeted by zing. B. is absorbed by the absorbent material 14 .
- the horizontally projecting edge 4 a of the mask 4 is so wide that it completely covers the edge 2 a of the tray 2 .
- the filled Tray 2 is sealed and can be further picking and processing supplied.
- the tray 2 is moved back together with the mask and with this engaged horizontally into the starting position for dropping off FIG. 5b , And it is a dropping of one or more products in the tray until it is completely filled.
- each of the circumferential side conveyor 17 outwardly projecting paddles 29 are arranged at opposite positions of the belts of the side conveyor 17 , push these paddles 29 against the trailing edge of the product 1 b and thereby direct the product in the rotational position about the horizontal axis in the transverse direction from when the side conveyor 17 to run slightly faster than the product conveyor 7 ".
- the product 1 runs b with its front side against a pair of paddles 29, and is thereby also in its Rotational position aligned around the vertical axis.
- FIG. 4b shows another transverse positioning device 5.2, in which in both side edge regions of the product conveyor 7 "in the height range above, in which the continuous product 1 b is reached, depending on a cross slide 16 is arranged, the front end face extends approximately in the direction 10 , and which can be moved by means of a slide punch 20 in the transverse direction 11 .
- the product 1 b passing through between the transverse slides 16 can be displaced and positioned in the transverse direction 11 by extension of one or both of the independently controllable sliding rams 20 by means of the respective transverse slide 16 .
- the slide punch 20 a limited distance in the direction 10 can be moved with the speed of the product 1 b or - which is not shown - are pivoted about an upright pivot axis, in which case, however, the product contacting end face of the cross slide 16 is preferably convex.
- a transverse position sensor 15 which determines the transverse position of the product 1 b passing by it, is arranged upstream of the transverse positioning device.
- This solution can serve to adjust the starting position of the cross slide 16 in the transverse direction 11 .
- the Querpositioniervoriques consists exclusively of such a transverse position sensor 15 , ie the transverse position of the product 1 b determined on the product conveyor, but not mechanically changed, but instead with the information of the transverse position of the tray 2 is set in the appropriate transverse position at the discharge point.
- the at the inlet is preferably carried out at such an angular velocity that the points of the two contact surfaces 31 a closest to one another move at the same speed in the direction of passage 10 as the product conveyor 7 ".

Description
Die Erfindung betrifft eine Einlegemaschine und ein Einlegeverfahren, mittels dem Produkte in oben offene, meist wannenförmige, Trays eingelegt und diese Trays anschließend durch eine auf dem Rand aufgesiegelte Siegelfolie dicht verschlossen werden.The invention relates to an inserting machine and a loading method, by means of which products are placed in open top, mostly trough-shaped, trays and these trays are then sealed tightly by a sealed on the edge sealing film.
Auf diese Art und Weise wird eine Vielzahl von Produkten verpackt, jedoch ist gerade das Einlegen von biegeschlaffen Teilen wie etwa Fleischscheiben dabei ein Problem, da auch solche Produkte im Tray exakt positioniert werden müssen.In this way, a variety of products is packed, but just the insertion of pliable parts such as sliced meat is a problem, as well as such products must be accurately positioned in the tray.
Dabei ist es bereits bekannt, biegeschlaffe Produkte wie etwa Fleischscheiben - einzeln oder gefächert übereinander gelegt zu Portionen - mittels eines Produktförderers heranzutransportieren und über dessen Abwurfkante in einen Tray fallenzulassen, der unter der Abwurfkante steht.It is already known, pliable products such as slices of meat - individually or fanned superimposed to portions - transport by means of a product conveyor and drop over the discharge edge in a tray that is below the discharge edge.
Dabei besteht das Problem der zu wählenden Geschwindigkeit:
- Je langsamer das Produkt über die Abwurfkante bewegt wird, umso größer ist das Kippmoment, welches das Produkt erfährt, und damit die Gefahr, dass das Produkt nicht auf der ursprünglichen Unterseite im Tray aufkommt, sondern ganz oder teilweise gewendet,
- je größer die Geschwindigkeit ist, mit der das Produkt über die Abwurfkante schießt, umso geringer ist dieses unerwünschte Kippmoment, jedoch umso größer ist die Relativgeschwindigkeit gegenüber dem Tray beim Auftreffen auf dem Tray, wenn der Tray stillsteht oder nur relativ langsam in Richtung der sich bewegenden Produkte mitbewegt wird, und damit das Risiko, dass das Produkt nicht eben auf dem Boden des Trays aufliegt.
- In diesem Zusammenhang sind bereits sog. Sprungbänder bekannt, bei denen die Abwurfkante des Produktförderers in Förderrichtung sehr schnell vor- und zurückbewegt werden kann, sodass zum Abwerfen die Abwurfkante unter dem Produkt schnell zurückgezogen wird, sodass praktisch kein Kippmoment mehr auftreten kann, sondern das Produkt mit Vertikalbeschleunigung nach unten absinkt, aber natürlich dennoch seine Horizontalgeschwindigkeit, die es hatte, als der Kontakt mit dem Produktförderer verloren ging, weiterhin beibehält.
Deshalb wird bei einem solchen Sprungband das Produkt kurz vor dem Verlassen des Produktbandes abgebremst und im Idealfall zum Stillstand gebracht.
- The slower the product is moved over the discharge edge, the greater is the tilting moment that the product experiences, and thus the risk that the product does not arise on the original underside in the tray, but turned completely or partially,
- the greater the speed at which the product shoots over the discharge edge, the lower is this undesirable overturning moment, but the greater is the relative speed with respect to the tray upon impact with the tray when the tray is stationary or relatively slow in the direction of the moving one Moving products, and thus the risk that the product is not just resting on the bottom of the tray.
- In this context, so-called. Jumping bands are already known in which the discharge edge of the product conveyor can be moved very fast back and forth in the conveying direction, so that for throwing off the discharge edge is quickly withdrawn under the product, so that virtually no overturning moment can occur, but the product with vertical acceleration going down but of course still maintaining its horizontal speed which it had when contact with the product conveyor was lost.
Therefore, in such a jump band, the product is braked shortly before leaving the product band and ideally brought to a standstill.
Allen drei Lösungen überlagert ist natürlich das Bestreben, die Effizienz der Vorrichtung zu steigern.Obviously, all three solutions are superimposed to increase the efficiency of the device.
In diesem Zusammenhang ist es aus der
Ferner ist es aus der
Ein besonderes Problem stellen dabei mit viel Flüssigkeit benetzte Produkte, wie etwa marinierte Scheiben von Frischfleisch, dar, weil es beim Einlegen dieser Produkte leicht geschehen kann, dass von dieser Flüssigkeit etwas auf den Rand des Trays tropft und an dieser Stelle keine dichte Versiegelung beim späteren Aufsiegeln der Siegelfolie mehr erzielt wird, wenn nicht vorher diese Verunreinigung auf dem Rand penibel entfernt wird.A particular problem in this case with a lot of liquid wetted products, such as marinated slices of fresh meat, because it can easily happen when inserting these products, that dripping from this liquid something on the edge of the tray and at this point no tight seal in the later Sealing the sealing film is achieved more if not previously this pollution is meticulously removed on the edge.
In diesem Zusammenhang ist es bereits bekannt, beim Einlegen der Produkte in den Tray den oberen Rand des stillstehenden Trays mittels einer abdeckenden Maske vor Verunreinigungen zu schützen. Die Maske wird jedoch immer wieder verwendet und maschinell bei jedem Tray an diesen angenähert und entfernt, um an den nächsten Tray angenähert zu werden.In this context, it is already known when inserting the products in the tray to protect the upper edge of the stationary tray by means of a mask covering from contamination. However, the mask is used over and over again and mechanically approximated and removed at each tray to approximate to the next tray.
So zeigen die
Dabei besteht immer noch die Gefahr, dass Flüssigkeitstopfen, die sich am Innenrand der Maske gebildet haben, bei der Relativbewegung zum Tray abtropfen und wiederum auf dem Rand des Trays auftreffen.There is still the danger that liquid plugs that have formed on the inner edge of the mask, drip during the relative movement to the tray and in turn impinge on the edge of the tray.
Es ist daher die Aufgabe gemäß der Erfindung, ein Verfahren und eine diesbezügliche Einlegemaschine zu schaffen, die das Verschmutzen der Oberseite des Randes des Trays durch Flüssigkeit, die von den einzulegenden Produkten stammt, vermeidet trotz hoher Einlegegeschwindigkeit.It is therefore the object of the invention to provide a method and a related insertion machine, which avoids the contamination of the top of the edge of the tray by liquid derived from the products to be introduced, despite high loading speed.
Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 8 gelöst. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.This object is solved by the features of
Hinsichtlich des Verfahrens wird diese Aufgabe gelöst, indem beim Abwurf der Produkte vom Produktförderer über dessen vorzugsweise feststehende Abwurfkante der aufnehmende Tray darunter in Durchlaufrichtung mit dem Produkt mitbewegt wird, vorzugsweise mit der gleichen Geschwindigkeit, die das abgeworfene Produkt zum Abwurfzeitpunkt besitzt- dadurch kann die Relativgeschwindigkeit in Durchlaufrichtung zwischen Produkt und Tray auf Null reduziert werden, sodass das meist biegeschlaffe Produkt auf dem Boden des Trays landet, ohne dort durch eine Relativgeschwindigkeit verformt oder gewellt zu werden.With regard to the method , this object is achieved by the receiving tray is moved along with the product in the passage direction with the product during the discharge of the products from the product conveyor via its preferably fixed discharge edge, preferably at the same speed, which has the discarded product at the time of discharge - thereby the relative speed be reduced to zero in the direction of flow between product and tray, so that the most pliable product on the ground of the tray lands without being deformed or corrugated there by a relative speed.
Dadurch kann das abzuwerfende Produkt oder die Portion aus mehreren Produkten auch mit einer sehr hohen Geschwindigkeit, insbesondere von mehr als 300 mm/s, über die Abwurfkante abgeworfen werden, was eine hohe Einlegerate und damit hohe Effizienz einer entsprechenden Einlegemaschine bewirkt.As a result, the product to be thrown off or the portion of several products can also be thrown off at a very high speed, in particular more than 300 mm / s, over the discharge edge, which results in a high insertion rate and thus high efficiency of a corresponding insertion machine.
Dennoch ist bei feuchten Produkten, insbesondere marinierten Fleischscheiben, die Gefahr groß, dass sich Flüssigkeitstropfen vom Produkt lösen, sei es während des Fluges des Produktes in Richtung Tray oder erst beim Aufschlagen des Produktes auf dem Boden des Trays, und sich durch Herumspritzen auf dem Rand des Trays ablagern.Nevertheless, with moist products, especially marinated meat slices, there is a high risk that drops of liquid from the product dissolve, either during the flight of the product in the direction of tray or only when the product on the bottom of the tray, and by spraying on the edge deposit the tray.
Beim anschließenden Aufsiegeln einer verschließenden Siegelfolie auf dem Rand des Trays können solche dort vorhandenen Flüssigkeitströpfchen Undichtigkeiten der Siegelnaht bewirken und in der Folge zu einem Verderben des Produktes im Tray führen.During the subsequent sealing of an occlusive sealing film on the edge of the tray, such liquid droplets present there can cause leaks in the sealed seam and, as a result, lead to spoilage of the product in the tray.
Erfindungsgemäß wird deshalb während des Abwurfes der Rand des Trays von einer darüber angeordneten Maske abgedeckt, die das Auftreffen von Flüssigkeitströpfchen verhindert. Die Maske befindet sich dabei in einem so geringen Abstand oberhalb des Randes des Trays oder liegt auf diesem sogar auf, dass ein Eindringen von Flüssigkeitströpfchen dazwischen nicht möglich ist. Vorzugsweise deckt die Maske den gesamten Rand des Trays ab.According to the invention, the edge of the tray is therefore covered by a mask arranged above it during the ejection, which prevents the impact of liquid droplets. The mask is located at such a small distance above the edge of the tray or is even on this that penetration of liquid droplets in between is not possible. Preferably, the mask covers the entire edge of the tray.
Da sich der Tray mit dem heranfliegenden Produkt mitbewegt, wird auch die abdeckende Maske mit dem Tray mitbewegt.As the tray moves with the approaching product, the mask covering it is also moved with the tray.
Damit das Produkt in den Tray gelangen kann, besitzt die - in der Regel ebenfalls wie der Tray horizontal liegende - Maske eine Durchgangsöffnung, die insbesondere nur geringfügig kleiner ist als die obere Öffnung des Trays. Von den Rändern dieser Durchgangsöffnung aus erstrecken sich umlaufend Wände nach unten. Beim Positionieren der Maske über dem Tray ragen diese Wände in die Vertiefung des Trays hinein und können auch in der Höhe so lang ausgebildet sein, dass sie mit ihrer Unterkante den Boden des Trays, insbesondere eine dort liegende saugfähige Lage, kontaktieren.In order for the product to be able to enter the tray, the mask-which likewise generally lies horizontally like the tray-has a passage opening, in particular, only slightly smaller than the upper opening of the tray. From the edges of this passage opening extending circumferentially walls down. When positioning the mask over the tray these walls protrude into the recess of the tray and can be formed so long in height that they contact the bottom of the tray with its lower edge, in particular an absorbent layer lying there.
Die umlaufenden Wände besitzen dabei einen solchen Außenumfang, dass sie gerade noch in die Vertiefung des Trays eingeführt werden können, wobei vorzugsweise die in der Regel leicht konisch sich nach unten verjüngenden Wände des Trays zur Zentrierung benutzt werden oder auch im Gegensatz dazu die Wände der Maske in dem im Tray eingesetzten Zustand an allen Stellen einen - allerdings möglichst geringen - Abstand zu den Wänden des Trays einhalten, damit keine an den Wänden des Trays haftenden Verschmutzungen an den Außenseiten der umlaufenden Wand der Maske haften bleiben können.The encircling walls have an outer circumference such that they can barely be inserted into the recess of the tray, whereby preferably the walls of the tray, which are generally tapered slightly conically, are used for centering or, in contrast, the walls of the mask In the state inserted in the tray, maintain a distance to the walls of the tray at all points, albeit as small as possible, so that no dirt adhering to the walls of the tray can adhere to the outer sides of the circumferential wall of the mask.
Vorzugsweise wird die Maske vor Beginn des Abwurfes in den Tray hinein abgesenkt, während des Abwurfes zusammen mit dem Tray in Vorschubrichtung mit bewegt und nach dem Beenden der Ablage des Produktes im Tray wieder nach oben aus dem Tray heraus bewegt und entgegen der Vorschubrichtung in die Ausgangsposition zurück bewegt.Preferably, the mask is lowered before the drop in the tray into it, moved during the drop along with the tray in the feed direction and moved after stopping the filing of the product in the tray back up out of the tray and against the feed direction to the starting position moved back.
Für die dafür notwendigen Relativbewegungen zwischen Tray und Maske wird vorzugsweise die Maske auf gleicher Höhe in Vorschubrichtung vor und zurück bewegt, während die vertikale Relativbewegung durch den Tray vollzogen wird, der vorzugsweise auf einer anhebbaren und absenkbaren Hubvorrichtung aufliegt.For the necessary relative movements between the tray and mask preferably the mask is moved back and forth at the same height in the feed direction, while the vertical relative movement is performed by the tray, which preferably rests on a liftable and lowerable lifting device.
Die Bewegung in Durchlaufrichtung kann auch mittels der Maske bewirkt werden, indem die formschlüssig im Tray eingetauchte Maske die Bewegung in Vorschubrichtung vollzieht und dabei den Tray mitnimmt.The movement in the direction of passage can also be effected by means of the mask by the form-fitting immersed in the tray mask performs the movement in the feed direction and thereby takes the tray.
Damit sich das abzuwerfende Produkt oder die abzuwerfende Portion auf dem heran transportierenden Produktförderer in der richtigen Drehlage um die Hochachse und an der richtigen Querposition auf dem Produktförderer befinden, werden sie vor dem Abwurf hinsichtlich vor allem der Querposition positioniert und vorzugsweise auch hinsichtlich der Drehlage um die Hochachse ausgerichtet, wofür mehrere Methoden zur Fügung stehen:.In order for the product to be thrown off or the portion to be thrown on the product conveyor to be conveyed in the correct rotational position about the vertical axis and at the correct transverse position on the product conveyor, they are positioned before the ejection with respect to the transverse position and preferably also with respect to the rotational position Aligned high axis, for which several methods are available :.
Die eine besteht darin, knapp oberhalb des Produktförderers, also im Höhenbereich des darauf liegenden Produktes oder der darauf liegenden Portion, beidseits des Produktes Banden mitlaufen zu lassen, vorzugsweise mit der Laufgeschwindigkeit des Produkt Förderers, wobei sich diese Banden in Durchlaufrichtung von einem zunächst großen Abstand auf einen dann kleinen Abstand aneinander annähern, welcher der Quererstreckung des zu positionierenden Produktes entspricht. Da dieser kleinste Abstand zwischen den mitlaufenden Banden sich an der Querposition befindet, an der sich das Produkt befinden soll, wird das Produkt in Querrichtung positioniert.One is to run just above the product conveyor, so in the height range of the product lying on it or portion lying on both sides of the product bands, preferably with the speed of the product conveyor, these bands in the direction of passage of an initially large distance approach each other to a small distance, which corresponds to the transverse extent of the product to be positioned. Since this smallest distance between the moving bands is at the transverse position at which the product is to be located, the product is positioned transversely.
Durch von den mitlaufenden Banden in Richtung Mitte des Produktförderers vorstehenden Paddeln im Höhenbereich des Produktes wird die hindurch Laufrichtung Vorderkante oder Endkante des Produktes auch hinsichtlich der Drehlage um die Hochachse ausgerichtet, indem diese an der entsprechenden Kante des Produktes zur Anlage gebracht werden. Auch die in Durchlaufrichtung liegenden Seitenkanten des Produktes werden durch solche mitlaufenden Banden in Durchlaufrichtung ausgerichtet.By projecting from the moving bands towards the center of the product conveyor paddles in the height range of the product through the direction of the leading edge or end edge of the product is also aligned with respect to the rotational position about the vertical axis by these are brought to the corresponding edge of the product to the plant. The side edges of the product lying in the direction of passage are also aligned in the direction of passage by such running bands.
Eine andere Möglichkeit besteht darin, durch in Querrichtung zur Mitte des Produktförderers hin ausfahrbare, beidseits angeordnete Querschieber das Produkt auf dem Produktförderer an die gewünschte Querposition zu schieben und dabei wegen der Anlage der Querschieber an den Seitenkanten das Produkt auch hinsichtlich seiner Drehungslage um die Hochachse auszurichten.Another possibility is to push through transversely to the center of the product conveyor out, both sides arranged cross slide the product on the product conveyor to the desired transverse position and thereby align the product also in terms of its rotational position about the vertical axis because of the system of cross slides on the side edges ,
Die Querschieber können dabei fest positioniert sein und somit nicht mit dem Produkt auf dem Produktförderer mitlaufen - denn die Querpositionierung soll vorzugsweise bei allen beschriebenen Möglichkeiten der Querpositionierung bei laufendem Produktförderer geschehen, um die Effizienz der Einlegemaschine nicht zu reduzieren - oder um eine Hochachse, die sich entfernt von der Kontaktfläche des Querschiebers zum Produkt hin befindet schwenkbar sein und dadurch begrenzt mit dem Produkt mit bewegbar sein, wobei dann vorzugsweise die Kontaktfläche in der Aufsicht betrachtet konvex gebogen ist.The cross slides can be firmly positioned and thus not run along with the product on the product conveyor - because the transverse positioning should preferably be done with all described possibilities of lateral positioning with the product conveyor running, not to reduce the efficiency of the insertion machine - or a vertical axis, which remote from the contact surface of the cross slide to the product to be pivoted and thereby be limited to be movable with the product, in which case preferably the contact surface viewed in the plan view is convexly curved.
Eine andere Möglichkeit besteht darin, auf beiden Seiten knapp über dem Produktförderer ein etwa Platten-förmiges Schwenksegment schwenkbar um eine aufrecht stehende Achse anzuordnen, dessen eine aufrecht stehende Schmalseite konvex gekrümmt ist, und zwar so, dass beim Verschwenken um die aufrecht stehende Achse in Laufrichtung diese aufrecht stehende Schmalseite, die Kontaktfläche zum Produkt hin, immer weiter in Richtung mit Längsmitte des Produktförderers vorsteht. Durch Verschwenken in Laufrichtung während sich das Produkt zwischen den beiden Schwenksegmenten befindet, wird das Produkt also in Richtung Längsmitte des Produktförderers verlagert.Another possibility is to arrange on both sides just above the product conveyor an approximately plate-shaped pivoting segment pivotable about an upright axis, whose upright narrow side is convexly curved, in such a way that when pivoting about the upright axis in the direction this upright narrow side, the contact surface towards the product, always protruding in the direction of the longitudinal center of the product conveyor. By pivoting in the direction of travel while the product is between the two pivoting segments, the product is thus displaced in the direction of the longitudinal center of the product conveyor.
Eine weitere Möglichkeit besteht darin, die Querposition des Produktes auf dem Produktförderer lediglich durch einen Sensor zu erfassen, aber nicht zu verhindern, stattdessen aber die Querposition von Maske und/oder Tray an der Abwurfstelle auf die Querposition des Produktes einzustellen.Another possibility is to detect the transverse position of the product on the product conveyor only by a sensor, but not to prevent, but instead adjust the transverse position of the mask and / or tray at the discharge point to the transverse position of the product.
Hinsichtlich der Vorrichtung wird die Aufgabe also dadurch gelöst, dass zunächst ein Produktförderer vorhanden ist, der einzelne Produkte oder zu Portionen zusammengestellte Produkte in Durchlaufrichtung herantransportiert und über seine in Durchlaufrichtung vordere Endkante, die Abwurfkante, die vorzugsweise Hindurchlaufrichtung feststehend ausgebildet ist, abwirft.With regard to the device , the object is thus achieved in that initially a product conveyor is present, the individual products or products assembled to portions transported in the direction of flow and about its front end in the direction of flow, the discharge edge, which is preferably formed fixed passage direction.
Unterhalb der Abwurfkante, also auf einem Niveau tiefer als die Abwurfkante, wird der jeweilige Tray, in dem das wenigstens eine Produkt abgelegt werden soll, welches über die Abwurfkante abgeworfen wird, unterhalb der Abwurfkante in Durchlaufrichtung mit der horizontalen Geschwindigkeit des abgeworfenen Produktes mitbewegt, sodass beim Auftreffen des Produktes auf dem Boden des Trays nach Möglichkeit keine horizontale Relativgeschwindigkeit zwischen Tray und Produkt vorliegt.Below the discharge edge, ie at a level lower than the discharge edge, the respective tray in which the at least one product is to be deposited, which is dropped over the discharge edge, moves below the discharge edge in the direction of passage with the horizontal speed of the discarded product, so When the product strikes the bottom of the tray, if possible, there is no horizontal relative velocity between the tray and the product.
Diese Bewegung des Trays kann bewirkt werden mithilfe eines Trayförderers, der sich dann vorzugsweise in Durchlaufrichtung erstreckt von einem Punkt vor der Abwurfkante bis zu einen Punkt nach der Abwurfkante.This movement of the tray can be effected by means of a tray conveyor, which then preferably extends in the direction of travel from a point in front of the discharge edge to a point after the discharge edge.
Vorzugsweise wird diese Bewegung des Trays beim Abwerfen jedoch bewirkt, indem die in den Tray eingetauchte Maske mittels eines Masken-Transporteurs horizontal in Durchlaufrichtung bewegt wird und dabei den Tray mitnimmt, der zu Beginn dieser Bewegung noch nicht auf einem Trayförderer auffliegt, sondern noch auf der Tragplatte einer Hubvorrichtung, die den Tray an die Maske heranheben kann, so dass der Trayförderer in Laufrichtung erst hinter der Abwurfkante beginnt, aber vorzugsweise in den Bewegungsbereich des Masken-Transporteurs hineinreicht.Preferably, however, this movement of the tray is caused when dropped by the mask immersed in the tray is moved horizontally in the direction of passage by means of a mask conveyor and thereby entrains the tray, which does not fly at the beginning of this movement on a Trayförderer, but still on the Supporting plate of a lifting device, which can raise the tray to the mask, so that the tray conveyor begins in the direction of movement behind the discharge edge, but preferably extends into the range of movement of the mask conveyor.
Die Vorrichtung umfasst ferner eine Steuerung, die den Tray relativ zum Produktförderer so steuern kann, dass der Tray genau unter dem von der Abwurfkante abgeworfenen Produkt mitbewegt wird, sodass das Produkt zum Schluss auf dem Boden des Trays liegt.The apparatus further includes a controller that can control the tray relative to the product conveyor so that the tray is moved just below the product dropped by the discharge edge so that the product ultimately lies on the bottom of the tray.
Dazu sind in der Regel Sensoren vorhanden, die die Ausgangsposition des Trays erfassen bzw. den Tray entsprechend positionieren, bevor dieser mit dem Produkt mitbewegt wird. Anstelle von Sensoren kann der Tray in seiner Ausgangslage auch dadurch positioniert werden, dass er durch das eintauchen der Maske, die sich in einer festen Ausgangsposition befindet, in seiner Ausgangslage zentriert wird.For this purpose, there are usually sensors that detect the starting position of the tray or position the tray accordingly, before it is moved with the product. Instead of sensors, the tray can also be positioned in its initial position by being centered in its initial position by immersing the mask, which is in a fixed starting position.
Vorzugsweise ist auch eine Schiebevorrichtung vorhanden, um die Tragplatte der Hubvorrichtung, auf der der Tray ruhen soll, zwischen einer Aufnahmeposition, in der sie mit einem neuen Tray geladen wird, und einer Abwurfposition für das Aufnehmen von Produkten in Querrichtung hin und her bewegt wird. Die Schiebevorrichtung ist vorzugsweise Bestandteil der Hubvorrichtung oder umgekehrt.Preferably, a pusher is also provided to reciprocate the support plate of the lifting device on which the tray is to rest between a pickup position in which it is loaded with a new tray and a picking position for picking up products in the transverse direction. The pusher is preferably part of the lifting device or vice versa.
Vorzugsweise ist zusätzlich eine in Durchlaufrichtung bewegbare Maske mit einem Rand zum Abdecken des Randes des Trays vorhanden, die beim Abwerfen des Produktes über dem Tray positioniert und mit diesem mitbewegt werden soll.Preferably, in addition, a movable in the direction of travel mask with a rim for covering the edge of the tray is present, which should be positioned when the product is dropped over the tray and moved with this.
Diese Maske besitzt eine Durchgangsöffnung, durch die hindurch das wenigstens eine Produkt von oben nach unten in den Tray fallen kann. Der um die Durchgangsöffnung herum sich erstreckende Rand der Maske ist so dimensioniert, dass er in der Aufsicht betrachtet, den oberen umlaufenden Rand des Trays abdecken kann, insbesondere vollständig abdecken kann.This mask has a passage opening through which the at least one product can fall from top to bottom in the tray. The edge of the mask, which extends around the passage opening, is dimensioned such that, viewed in the top view, it can cover the upper peripheral edge of the tray, in particular it can completely cover it.
Von der Innenkontur des Randes der Maske aus, also um die Durchgangsöffnung herum, erstrecken sich umlaufende Wände von dem Rand aus nach unten, die beim Anordnen der Maske auf dem Tray in die Vertiefung des Trays eintauchen.From the inner contour of the edge of the mask, so around the passage opening around, circumferential walls extend from the edge downwards, which dive into the recess of the tray when placing the mask on the tray.
Für das Eintauchen und wieder heraus Bewegen ist eine vertikale Relativbewegung zwischen Maske und Tray notwendig, die von einer Hubvorrichtung bewirkt wird, die vorzugsweise den jeweiligen Tray an die Maske heran anhebt und vorzugsweise nach Einlegen der Produkte von der Maske nach unten absenkt, bis der Tray wieder außer Eingriff mit der Maske ist.For the immersion and moving out again, a relative vertical movement between the mask and tray is necessary, which is caused by a lifting device, which preferably raises the respective tray to the mask and preferably after lowering the products of the mask down to the tray is again out of engagement with the mask.
Die Maske selbst wird vorzugsweise nur horizontal Durchlaufrichtung vor und zurück bewegt und unterliegt keiner Vertikalbewegung, vor allem deshalb, weil im umgekehrten Fall, also bei einer Vertikalbewegung der Maske, der vertikale Abstand zwischen mit der Maske ausgestattetem Tray und der Abwurfposition, also dem Produktförderer, größer wäre, was für das zielsichere Ablegen der Produkte im Tray nachteilig wäre.The mask itself is preferably only moved horizontally forward and backward and is not subject to any vertical movement, above all because in the opposite case, ie in a vertical movement of the mask, the vertical distance between the tray equipped with the mask and the discharge position, So the product conveyor, would be larger, which would be detrimental for the purposeful storage of the products in the tray.
Als Trayförderer, der den jeweiligen Tray während des Abwurfes mit dem Produkt horizontal mitbewegt, kann auch die Maske selbst verwendet werden, die ja formschlüssig in den Tray eintaucht. Indem also die Maske zum Beispiel mittels eines Maskentransporteurs in Durchlaufrichtung bewegt wird, kann sie dabei den Tray mitnehmen, der hierfür lediglich auf einer Tragplatte entlang gleiten muss, welche beispielsweise Bestandteil der Hubvorrichtung sein kann.As a tray conveyor, which moves the respective tray horizontally during the ejection with the product, the mask itself can also be used, which dips positively into the tray. Thus, by moving the mask in the direction of passage, for example by means of a mask transporter, it can take along the tray, which for this purpose only has to slide along a support plate, which may be part of the lifting device, for example.
Die durch die Maske hindurch fallenden nassen Produkte werden Flüssigkeitstropfen an der Maske hinterlassen, sei es auf deren oberen Rand oder an der Innenseite der nach unten gerichteten Wände der Maske. Diese Flüssigkeitstropfen werden entlang der Wände nach unten fließen und irgendwann von der Unterkante der Wand nach unten abtropfen.The wet products passing through the mask will leave drops of liquid on the mask, whether on the upper edge or on the inside of the downwardly facing walls of the mask. These drops of liquid will flow down the walls and eventually drip down from the bottom edge of the wall.
Um zu vermeiden, dass ein solcher abtropfender Flüssigkeitstropfen von der Maske während der Relativbewegung von Tray und Maske in Querrichtung auf den oberen Rand des Trays abtropft, werden an der Unterkante der Wände hängende Flüssigkeitstropfen vorzugsweise aktiv beseitigt.In order to avoid that such a dripping drop of liquid dripping from the mask during the relative movement of tray and mask in the transverse direction on the upper edge of the tray, preferably hanging on the lower edge of the walls hanging liquid drops are actively eliminated.
Zu diesem Zweck ist entweder die Maske mit ihren Wänden so dimensioniert, dass die Wände beim Eintauchen in den Tray, dessen Innenraum sich in der Regel konisch sih nach oben erweitert, die Innenseiten der Wände des Trays berühren und dadurch an den Wänden der Maske anhaftende Flüssigkeit vom Tray abgenommen wird.For this purpose, either the mask is dimensioned with its walls so that the walls when immersed in the tray, the interior of which is usually conically sih upward, touching the insides of the walls of the tray and thereby adhering to the walls of the mask liquid removed from the tray.
Eine andere oder auch alternativ anzuwendende Möglichkeit besteht darin, dass der Boden der Trays mit einem Saugmaterial bedeckt ist, welches Flüssigkeit aufsaugt, und die nach unten ragenden Wände der Maske sind so lang ausgebildet, dass beim Eintauchen der Maske in den Tray die Unterkante der Wände der Maske auf dem Saugmaterial des Bodens aufsitzt und dadurch dort vorhandene Flüssigkeitstropfen von dem Saugmaterial aufgenommen werden.Another or alternative alternative is that the bottom of the trays is covered with a suction material that absorbs liquid, and the downwardly projecting walls of the mask are formed so long that when immersing the mask in the tray, the lower edge of the walls the mask sits on the absorbent material of the floor and thereby existing liquid drops are absorbed by the absorbent material.
Damit das Hindurchfallen der Produkte durch die Durchgangsöffnung möglichst einfach ist, sollte diese so groß wie möglich gestaltet sein. Die Begrenzung liegt darin, dass die um die Durchgangsöffnung herum verlaufenden Wände noch in die Vertiefung des Trays passen müssen.Thus, the falling through of the products through the through hole is as simple as possible, this should be designed as large as possible. The limitation lies in the fact that the walls running around the passage opening still have to fit into the recess of the tray.
Eine erste Lösung besteht darin, die Durchgangsöffnung und damit den Außenumfang der Wände der Maske so groß zu dimensionieren, dass sie beim Einführen in den Tray dessen Wände - die den meist konisch sich nach unten verjüngenden Innenraum umgeben -kontaktieren und der Tray zum Zentrieren benutzt wird.A first solution is to dimension the passage opening and thus the outer circumference of the walls of the mask so large that when they are inserted into the tray, the walls thereof-which surround the conically tapering interior space-contact and the tray is used for centering ,
Dadurch kommen jedoch die Außenseiten der Wände der Maske mit dem Tray in Berührung, was einerseits an der Maske anhaftende Flüssigkeit abnehmen kann, wie oben dargelegt, aber es könnten auch Verschmutzungen in umgekehrter Richtung von den Tray auf die Maske übertragen werden.As a result, however, the outer sides of the walls of the mask come into contact with the tray, which on the one hand can remove liquid adhering to the mask, as stated above, but also contaminants could be transferred in the opposite direction from the tray to the mask.
Bevorzugt ist deshalb, dass die Maske passgenau von oben in den Tray hinein abgesenkt wird, jedoch auch während des Mitbewegens mit dem Tray die Wände der Maske immer einen geringen Abstand zu den Wänden des Trays einhalten, was jedoch die Durchgangsöffnung durch die Maske naturgemäß verringert.It is therefore preferred that the mask is lowered accurately from above into the tray, however, even while moving with the tray, the walls of the mask always keep a small distance to the walls of the tray, which, however, reduces the passage opening through the mask naturally.
In diesem Fall ist es jedoch nicht möglich, die Maske als Trayförderer zu benutzen, sondern dann müssen die Trays einerseits und die Maske andererseits jeweils separat über einen Förderer synchron bewegt werden.In this case, however, it is not possible to use the mask as a tray conveyor, but then the trays on the one hand and the mask on the other hand have to be moved synchronously separately via a conveyor.
Zusätzlich kann vom Rand der Maske auf einer Seite, nämlich der in Durchlaufrichtung vorderen Seite, ein Anschlag nach oben aufragen, für den Fall dass ein im Tray abzulegendes Produkt nicht direkt die Durchgangsöffnung der Maske trifft sondern etwas zu weit fliegt. Ein solches Produkt wird dann gegen den Anschlag stoßen, dadurch schlagartig abgebremst werden und nach unten in die Durchgangsöffnung der Maske fallen, da sich der Anschlag unmittelbar am Rand der Durchgangsöffnung befindet.In addition, from the edge of the mask on one side, namely the front side in the direction of passage, a stop rise up, in the event that a product to be deposited in the tray does not directly hit the through hole of the mask but something flies too far. Such a product will then abut against the stop, thereby be braked abruptly and fall down into the through hole of the mask, since the stop is located directly on the edge of the through hole.

Den Aufbau der Maschine lassen am besten die
Vor der Frontwand des schrankartigen Maschinengehäuses 30 sind die Handhabungseinheiten für die Produkte 1a, b, vor allem die diversen Förderer, offen montiert, sodass sie von einem Bediener, der vor der Maschine steht, gut einsehbar und zugänglich sind:
- Von rechts her werden die
Produkte 1a, b - entweder einzeln oder bereits in Portionen 1', beispielsweise gefächert übereinander gelegt wie inden Figuren 5 dargestellt - auf einem ersten Produktförderer 7" herantransportiert, und noch vor dem Erreichen der auf diesem Produktförderer 7"montierten Querpositioniervorrichtung 5 mittels eines Querpositions-Sensors 15, der vorzugsweiseam Gehäuse 30 der Maschine montiert ist, die Position desProduktes 1b oder der herantransportierten Portion 1', die aus mehreren solcher Produkten besteht, inQuerrichtung 11auf dem Produktförderer 7" bestimmt.
- From the right, the
products 1 a, b - either individually or already in portions 1 ', for example, laid one above the other as in theFigures 5 illustrated - transported on afirst product conveyor 7 " , and even before reaching the mounted on thisproduct conveyor 7"transverse positioning device 5 by means of atransverse position sensor 15, which is preferably mounted on thehousing 30 of the machine, the position of theproduct 1 b or the transported Portion 1 ', which consists of several such products, determined in thetransverse direction 11 on theproduct conveyor 7 " .
Die Querrichtung 11 steht lotrecht zur Durchlaufrichtung 10 der Produkte, also der Förderrichtung der Produktförderer 7, 7', 7" und des Trayförderers 8. The
In der Querpositioniervorrichtung 5 wird das Produkt 1b an die richtige Querposition geschoben und auch hinsichtlich seiner Drehlage um die Hochachse ausgerichtet, also vor allem bei Portionen, deren Seitenkanten noch nicht parallel zur Durchlaufrichtung 10 ausgerichtet sind.In the
Von diesem ersten Produktförderer 7" wird das Produkt 1 b oder die Portion 1' aus Produkten 1a, b...an einem in Durchlaufrichtung 10 nachfolgenden Produktförderer 7' und von diesem auf den nächsten in Durchlaufrichtung 10 nachfolgenden Produktförderer 7, den letzten Produktförderer in Durchlaufrichtung 10, übergeben.From this
Dieser letzte Produktförderer 7 besitzt in seinem Endbereich einen schräg nach unten weisenden Verlauf des Obertrums dieses endlos umlaufenden Produktförderers 7, welches um eine Umlenkwalze mit sehr geringem Durchmesser umgelenkt wird zwecks Bildung einer Abwurfkante 7a als Ende dieses Produktförderers 7. This
Ein Produkt 1a, welches auf dem vorzugsweise mit konstanter Geschwindigkeit zumindest während des Abwurfvorganges laufendem Produktförderer 7 transportiert wird, läuft am Ende im Schrägbereich bereits schräg nach unten und setzt aufgrund seiner Geschwindigkeit diese Richtung auch nach Überlaufen der Abwurfkante 7a im freien Fall fort und soll in einen darunter befindlichen Tray 2 fallen, wie im Folgenden anhand der
Ein solcher Tray 2 ist nur in

Da der Abstand 19 in Durchlaufrichtung 10 am Beginn deutlich größer ist als die Quererstreckung eines Produktes 1b, wird ein Produkt 1b auch dann, wenn es in Querrichtung 11 nicht an der richtigen Querposition auf dem Produktförderer 7" aufliegt, durch Hindurchschleusen zwischen den beiden umlaufenden Seitenförderern 17 von deren gegeneinander gerichteten Trumen an die richtige Querposition geschoben.Since the distance 19 in the direction of
Da von den umlaufenden Seitenförderer 17 jeweils nach außen vorstehende Paddel 29 an einander gegenüber liegenden Positionen der Bänder der Seitenförderer 17 angeordnet sind, schieben diese Paddel 29 gegen die Hinterkante des Produktes 1b und richten das Produkt dadurch in der Drehlage um die horizontale Achse in Querrichtung aus, falls die Seitenförderer 17 etwas schneller laufen als der Produktförderer 7". Falls jedoch die Seitenförderer 17 etwas langsamer laufen als der Produktförderer 7", läuft das Produkt 1b mit seiner Vorderseite gegen ein Paar von Paddeln 29, und wird hierdurch ebenso in seiner Drehlage um die vertikale Achse ausgerichtet.Since each of the

Es gibt jedoch auch eine andere Lösung, in der die Querpositioniervorrichtung ausschließlich aus einem solchen Querpositions-Sensor 15 besteht, also die Querposition des Produktes 1b auf dem Produktförderer nur ermittelt, aber nicht mechanisch verändert wird, sondern stattdessen mit der Information der Querposition der Tray 2 in die entsprechende Querposition an der Abwurfstelle eingestellt wird.However, there is also another solution, in which the Querpositioniervorrichtung consists exclusively of such a
- Dabei ist beidseits im Randbereich des
Produktförderers 7"knapp darüber, also im Höhenbereich des darauf liegenden Produktes 1b, ein in einer horizontalen Ebene liegendes, plattenförmiges Schwenksegment 31 vorhanden, welches um eine aufrechte Schwenkachse 21 verschwenkbar ist.Dieses Schwenksegment 31 weist eine dem dazwischen hindurch transportierten Produkt1 b zugewandte Kontaktfläche 31a auf, die eine der Schmalseiten der Platte darstellt, und welche derart konvex gekrümmt ist, dass ihr Abstand zur aufrecht stehenden Schwenkachse 21 entgegen der Durchlaufrichtung 10 zunimmt.
