Description

Die vorliegende Erfindung betrifft eine Fördereinrichtung zum Zubringen von flächigen Erzeugnissen zu einer Verarbeitungsmaschine für Druckereiprodukte gemäss dem Oberbegriff des Anspruchs 1 und eine Einrichtung zum Verarbeiten von Druckereiprodukten gemäss dem Oberbegriff des Anspruchs 8. The present invention relates to a conveyor for feeding flat products to a processing machine for printed products according to the preamble of claim 1 and a facility for processing printed products according to the Preamble of claim 8.

Eine Fördereinrichtung dieser Art ist in der EP-A-0 606 550 und EP-A-0 606 549 offenbart. Sie weist ein drehend angetriebenes Trägerrad auf, an dem in Umfangsrichtung im Abstand steuerbare Klammern über Tragarm und Lenkorgan angeordnet sind. Tragarm und Lenkorgan sind jeweils am Trägerrad um zu dessen Drehachse parallelle Achsen schwenkbar gelagert, um gelenkviereckartig die Lage der jeweiligen Klammer in Abhängigkeit von der Schwenklage des betreffenden Tragarms zu steuern. Ist der Tragarm in Umlaufrichtung gesehen gegen hinten verschwenkt, ist das Maul der Klammer gegen vorne gerichtet. Sie nimmt diese Lage beim Durchlaufen eines Uebernahmebereichs ein, in welchem sie ein Erzeugnis bei dessen in Umlaufrichtung gesehen nachlaufenden Kante erfasst, das mittels eines Bandförderers tangential zur Bewegungsbahn der Klammer, aber mit bezüglich dieser geringerer Geschwindigkeit dem Uebernahmebereich zugeführt und im Uebernahmebereich gefördert wird. Beim Verschwenken des Tragarms aus seiner rückwärts gerichteten Endlage in eine etwa radiale Lage wird die Klammer in Abhängigkeit von der Bewegung des Tragarms entgegen der Umlaufrichtung verschwenkt, um dabei das Erzeugnis in einem Uebergabebereich zwischen Wandelemente einer Verarbeitungsmaschine für Druckereiprodukte einzuführen und dort an ein an einem der Wandelemente anliegenden Druckereiprodukt anzulegen oder gesteuert freizugeben. Die beiden Klemmbacken einer Klammer sind am betreffenden Tragarm schwenkbar gelagert, wobei die eine der Klemmbacken am Lenkorgan und die andere der Klemmbacken an einem kurbeltriebartigen Oeffnungsorgan angelenkt ist. Letzteres weist eine Folgerolle auf, mit der zum Oeffnen der Klammer im Uebernahme- und im Uebergabebereich je eine Oeffnungskulisse zusammenwirkt. Um das Erfassen der Erzeugnisse durch die Klammern im Uebernahmebereich zu gewährleisten, werden jene immer mit zur Umlaufrichtung gleicher Richtung, aber mit kleinerer Geschwindigkeit gefördert. Das Uebernehmen von im Uebernahmebereich, in Umlaufrichtung gesehen, stillstehenden Erzeugnissen ist in den genannten Dokumenten nicht erwähnt, noch ist die dort offenbarte Fördereinrichtung dazu vorgesehen. A conveyor of this type is in EP-A-0 606 550 and EP-A-0 606 549 disclosed. She has a spinning driven carrier wheel on which in the circumferential direction in Distance controllable brackets over the support arm and steering element are arranged. Support arm and steering element are each on Carrier wheel about axes parallel to its axis of rotation pivoted to the position of the quadrilateral respective bracket depending on the pivoting position of the to control the relevant support arm. Is the support arm in the direction of rotation seen pivoted towards the rear, that's it The mouth of the clip is facing forward. She takes this Position when passing through a takeover area in which they produce in the direction of rotation seen trailing edge detected by a Belt conveyor tangential to the path of movement of the clamp, but with regard to this slower speed Takeover area fed and in the takeover area is promoted. When pivoting the support arm out of its rearward end position in an approximately radial position the bracket is dependent on the movement of the Support arm pivoted against the direction of rotation to thereby the product in a transfer area between wall elements a processing machine for printed products introduce and there at one of the wall elements adjacent printing product to create or controlled to release. The two jaws of a clamp are on relevant support arm pivoted, the one the jaws on the steering member and the other of the jaws hinged to a crank mechanism-like opening member is. The latter has a follow-up role with which to open the clip in the takeover and transfer area one opening backdrop interacts. To do that Capture the products by the brackets in the takeover area to ensure that those are always with Direction of rotation in the same direction, but with a smaller one Promoted speed. The takeover of im Takeover area, seen in the direction of rotation, stationary Products are not in the mentioned documents mentioned, is still the conveyor disclosed there provided for this.

Eine weitere Fördereinrichtung ist in der älteren EP-A-0 675 062 offenbart. Sie weist ein drehend angetriebenes Trägerrad auf, an dem in Umfangsrichtung verteilt Tragelemente befestigt sind, an welchen je ein Tragarm und Lenkorgan um zur Drehachse des Trägerrades parallelle Schwenkachsen angelenkt ist. Im freien Endbereich jedes Tragarmes ist an diesem ein zur Drehachse paralleller Lagerschaft angeordnet, an dem zwei zusammenwirkende, in Schliessrichtung vorgespannte Klemmbacken einer Klammer schwenkbar gelagert sind. Eine erste der Klemmbacken ist mit dem Lenkorgan verbunden, um die Klammer um ihre Anlenkung am Tragarm zu verschwenken. Sowohl die Schwenklage der Tragarme, als auch die Lage der Lenkorgane ist getrennt voneinander gesteuert, um die Klammer auch unabhängig von einer Schwenkbewegung der Tragarme zu verschwenken. Dies ermöglicht insbesondere das Bewegen der Klammer in Umlaufrichtung relativ zu den Tragelementen, wobei die Schwenklage der Klammern steuerbar ist, was besondere Vorteile beim Uebernehmen und Abgeben der Erzeugnisse sowie gegebenenfalls beim Vorbeiführen der Erzeugnisse in definierter Lage und mit gegebener Geschwindigkeit an Bearbeitungsstationen mit sich bringt. Vor der Uebernahme eines Erzeugnisses werden die Klammern in eine Lage verschwenkt, in welcher das durch die Klemmbacken gebildete Maul in Umlaufrichtung nach vorne gerichtet ist. Dabei kommt ein mit der in dieser Lage radial aussen liegenden zweiten Klemmbacke verbundenes Anschlagelement an einen Gegenanschlag am Tragarm zur Anlage, wodurch diese zweite Klemmbacke am weiteren Folgen der durch das Lenkorgan gesteuerten weiteren Schwenkbewegung der ersten Klemmbacke gehindert ist, was zum Oeffnen der Klammer führt. Zum Abgeben der Erzeugnisse an die Verarbeitungsmaschine werden die Klammern mit in etwa radial nach aussen gerichtetem Maul zwischen jeweils zwei aufeinanderfolgende Wandelemente der Verarbeitungsmaschine eingeführt. Der betreffende Tragarm wird dann in Umlaufrichtung nach vorne geschwenkt, bis sich die zweite Klemmbacke mit einer an ihrem freien Ende gelagerten Andrückwalze über das Erzeugnis am in Umlaufrichtung vorauslaufenden Wandelement abstützt. Beim anschliessenden Schwenken der ersten Klemmbacke mittels des Lenkorgans wird dadurch die zweite Klemmbacke am Mitschwenken gehindert, was das Oeffnen der Klammern und Freigeben des Erzeugnisses zur Folge hat.Another conveyor is in the older EP-A-0 675 062 disclosed. It has a rotating drive Carrier wheel on the support elements distributed in the circumferential direction are attached, to each of which a support arm and steering element about pivot axes parallel to the axis of rotation of the carrier wheel is articulated. In the free end area of each support arm there is a stock shaft parallel to the axis of rotation arranged, on which two interacting, in the closing direction preloaded jaws of a clamp can be swiveled are stored. A first of the jaws is with the Steering element connected to the bracket around its articulation on Pivot arm. Both the swivel position of the support arms, as well as the position of the steering members is separate from each other controlled to the parenthesis independently of to pivot a pivoting movement of the support arms. This in particular enables the clamp to be moved in the circumferential direction relative to the support elements, the pivot position the brackets is controllable, which has particular advantages when taking over and delivering the products and, if necessary when passing the products in a defined Location and at a given speed at processing stations brings with it. Before taking over a product the brackets are swiveled into a position in which the mouth formed by the jaws in the direction of rotation is facing forward. One comes with the in this position, the second clamping jaw lying radially on the outside connected stop element to a counter stop on Support arm to the system, whereby this second jaw on further consequences of the others controlled by the steering element Pivoting movement of the first jaw is prevented, which leads to the opening of the bracket. To deliver the products the brackets are attached to the processing machine roughly radially outward mouth between two successive wall elements of the processing machine introduced. The relevant arm will then pivoted forward in the direction of rotation until the second jaw with one at its free end Pressure roller over the product in the direction of rotation supports the leading wall element. At the subsequent Swiveling the first jaw by means of the steering element this prevents the second jaw from pivoting, what the opening of the brackets and releasing the Product.

Die in der Figur 1 stark vereinfacht gezeigte Einrichtung zum Verarbeiten von Druckereiprodukten weist eine Fördereinrichtung 10 mit in Umlaufrichtung U hintereinander angeordneten Klammern 12 auf, die dazu bestimmt sind, beim Vorbeibewegen an einer Lieferstelle 14 jeweils ein Erzeugnis 16', im vorliegenden Fall einen gefalteten Druckbogen 16, ein sogenannter Beihefter, zu erfassen und einem Uebergabebereich 18 zuzuführen, wo die Erzeugnisse 16' an eine Verarbeitungsmaschine 20 abgegeben werden. Eine Verarbeitungsmaschine 20 dieser Art ist in der EP-A-0 550 828 und der entsprechenden US-A-5,324,014 gezeigt und ausführlich beschrieben. Sie weist um eine Trommelachse 22 herum in Umfangsrichtung gleichmässig verteilte Wandelemente 24 auf, die radial angeordnet sind und mit ihrem radial äusseren Ende je eine parallel zur Trommelachse 22 verlaufende sattelförmige Auflage 26 für die Druckbogen 16 und weitere zu verarbeitende Druckereiprodukte 27 bilden.The device shown in greatly simplified form in FIG. 1 has a conveyor for processing printed products 10 with one behind the other in the direction of rotation U. arranged brackets 12, which are intended to Moving past a delivery point 14 one product at a time 16 ', in the present case a folded printed sheet 16, a so-called insert, to capture and one Transfer area 18 to feed where the products 16 ' a processing machine 20 are delivered. A processing machine 20 of this type is in EP-A-0 550 828 and corresponding US-A-5,324,014 described. It points around a drum axis 22 Wall elements 24 distributed uniformly in the circumferential direction on that are arranged radially and with their radial outer end each running parallel to the drum axis 22 saddle-shaped support 26 for the printed sheets 16 and form further printed products 27 to be processed.

An einem Trägerrad 28 der Fördereinrichtung 10, das an einem Maschinengestell 30 mit parallel zur Trommelachse 22 verlaufender Drehachse 32 gelagert ist und das entgegengesetzt der Drehrichtung D der Verarbeitungsmaschine 20 in Umlaufrichtung U angetrieben ist, sind in Umfangsrichtung gleichmässig verteilt auslegerartige Tragelemente 34 befestigt, an denen je ein Tragarm 36 und ein Lenkorgan 38 schwenkbar gelagert ist. Die Tragelemente 34 laufen somit entlang einer in sich geschlossenen kreisförmigen Umlaufbahn um die Drehachse 32 um. Die Tragarme 36 sind in der Art eines zweiarmigen Winkelhebels ausgebildet, an dessen einem Arm 40 eine Klammer 12 schwenkbar und an dessen anderem Arm 42 eine Folgerolle 44 drehbar gelagert ist, wie dies insbesondere den Figuren 2 und 3 entnehmbar und weiter unten ausführlich beschrieben ist.On a carrier wheel 28 of the conveyor 10, the a machine frame 30 with parallel to the drum axis 22 extending axis of rotation 32 is mounted and the opposite the direction of rotation D of the processing machine 20 in Circulation direction U is driven in the circumferential direction attached uniformly distributed cantilever-like support elements 34, on which a support arm 36 and a steering member 38 is pivotally mounted. The support elements 34 thus run along a self-contained circular orbit about the axis of rotation 32. The support arms 36 are in the Formed a two-armed angle lever, on the an arm 40 a bracket 12 pivoted and on the another arm 42 a follower roller 44 is rotatably mounted, as can be seen in particular from FIGS. 2 and 3 and is described in detail below.

Jede Klammer 12 weist zwei zusammenwirkende, ein Klammermaul 46 bildende Klemmbacken 48, 50 auf, von denen jeweils eine erste Klemmbacke 48 zum Verschwenken der Klammer 12 mit dem betreffenden Lenkorgan 38 verbunden ist. Am Lenkorgan 38 ist eine Steuerrolle 52 drehbar gelagert.Each clip 12 has two interacting, one clip mouth 46 forming jaws 48, 50, each of which a first jaw 48 for pivoting the bracket 12 is connected to the relevant steering member 38. On the steering organ 38, a control roller 52 is rotatably mounted.

Ein am Maschinengestell 30 befestigter Steuerring 54, siehe auch Figur 4, weist zwei um das Trägerrad 28 herumverlaufende, in sich geschlossene, nutartige Steuerkulissen 56, 58 auf. In einer ersten Steuerkulisse 56 sind alle an den Tragarmen 36 gelagerten Folgerollen 44 geführt, wogegen in der radial innenliegenden zweiten Steuerkulisse 58 alle auf die Lenkorgane 38 einwirkenden Steuerrollen 52 geführt sind. Die erste Steuerkulisse 56 bestimmt somit die Schwenklage der Tragarme 36 und die zweite Steuerkulisse 58 die Schwenklage der an den Tragarmen 36 gelagerten Klammern 12. Der Steuerring 54 mit den Steuerkulissen 56, 58 und die damit zusammenwirkenden Folge- und Steuerrollen 44, 52 bilden somit eine Steuereinrichtung 60 zum getrennten Steuern der Tragarme 36 und Lenkorgane 38, um die Klammern 12 um ihre Anlenkung an den Tragarmen 36 auch unabhängig von der Schwenkbewegung der Tragarme 36 zu verschwenken. A control ring 54 attached to the machine frame 30, see also FIG. 4, has two running around the carrier wheel 28, self-contained, groove-like control links 56, 58 on. All are in a first control link 56 guided on the support arms 36 mounted follow rollers 44, whereas in the radially inner second control link 58 all control rollers 52 acting on the steering members 38 are led. The first control link 56 thus determines the pivot position of the support arms 36 and the second control link 58 the pivoting position of those mounted on the support arms 36 Brackets 12. The control ring 54 with the control links 56, 58 and the related follow-up and steering roles 44, 52 thus form a control device 60 for separate control of the support arms 36 and steering members 38 to the brackets 12 also about their articulation on the support arms 36 to pivot regardless of the pivoting movement of the support arms 36.

Weiter ist im Uebergabebereich 18 eine Oeffnungskulisse 62 ortsfest angeordnet, die dazu bestimmt ist, zum Oeffnen der Klammer 12 auf die zweite Klemmbacke 50 einzuwirken.There is also an opening backdrop 62 in the transfer area 18 arranged fixed, which is intended to be opened the clamp 12 to act on the second jaw 50.

Die Klammern 12 sind dazu bestimmt, mit ihrem in Umlaufrichtung U gegen vorne gerichteten Klammermaul 46 bei der Lieferstelle 14 einen gefalteten Druckbogen 16 bei dessen Falz 66 zu fassen und mit der diesem gegenüberliegenden Kante 68 voraus dem Uebergabebereich 18 zuzuführen, an dessen Anfang ein Oeffnungsaggregat 70 angeordnet ist. Dieses ist dazu bestimmt, jeweils einen ersten Druckbogenteil 72 in einem dem Falz 66 gegenüberliegenden Randbereich zu fassen und vom anderen zweiten Druckbogenteil 74 abzuheben, so, dass jeweils ein Wandelement 24 der Verarbeitungsmaschine 20 zwischen die von einander abgehobenen Druckbogenteile 72, 74 einfahren kann. Das Oeffnungsaggregat 70 gibt dann den ersten Druckbogenteil 72 frei, wonach im Endbereich des Uebergabebereichs 18 mittels der Oeffnungskulisse 62 die Klammern 12 geöffnet werden, um die Druckbogen 16 freizugeben, die dann rittlings auf die sattelförmigen Auflagen 26, bzw. auf bereits auf diesen angeordnete Druckereiprodukte 27 fallen.The brackets 12 are intended with their in the circumferential direction U towards the front clamp mouth 46 at the Delivery point 14 a folded printed sheet 16 at its Fold 66 to grasp and with the opposite To feed edge 68 ahead of the transfer area 18 the beginning of which an opening unit 70 is arranged. This is intended to be a first printed sheet part 72 in an edge region opposite the fold 66 to grasp and from the other second sheet 74 to take off so that one wall element 24 of the processing machine 20 between those set apart Sheet parts 72, 74 can retract. The opening unit 70 then releases the first sheet part 72, after which in the end area of the transfer area 18 by means of the opening backdrop 62 the clips 12 are opened to the Release sheet 16, which then astride the saddle-shaped pads 26, or already on this arranged printed products 27 fall.

Eine Zubringeinrichtung 76 hat die Aufgabe, bei der Lieferstelle 14 für jede Klammer 12 ein Erzeugnis 16', im vorliegenden Fall einen Druckbogen 16, in der richtigen Lage bereitzustellen. Die in der Figur 1 gezeigte Zubringeinrichtung 76 ist in der älteren EP-A-0 675 061 offenbart. Eine weitere, zum selben Zweck geeignete Zubringeinrichtung ist in der ebenfalls älteren EP-A-0 675 062 gezeigt und beschrieben. Was den Aufbau und die Funktionsweise dieser Zubringeinrichtungen 76 betrifft, wird ausdrücklich auf diese Dokumente verwiesen. A feed device 76 has the task of Delivery point 14 for each clip 12 a product 16 ', in present case a press sheet 16, in the correct Able to provide. The feed device shown in Figure 1 76 is in the older EP-A-0 675 061 disclosed. Another, for the same purpose A suitable feeder is also in the older one EP-A-0 675 062 shown and described. As for the structure and operation of these feeders 76 concerns, is expressly on this Referenced documents.

Der Aufbau der Klammern 12 und deren Steuerung wird nun anhand der Figuren 2 und 3 näher beschrieben. Der Tragarm 36 weist zwei identische Tragarmteile 78 auf, die je auf einer Seite des Tragelementes 34 angeordnet und mittels einer Anlenkachse 80 am Tragelement 34 gelagert sind. Beiderends sind diese Tragarmteile 78 über Lagerschäfte 82, 82' miteinander verbunden, wobei am ersten Lagerschaft 82 auf der einen Seite des Tragarms 36 die Folgerolle 44 und am zweiten Lagerschaft 82' auf der anderen Seite des Tragarm 36 die beiden Klemmbacken 48, 50 der Klammer 12 gelagert sind.The structure of the brackets 12 and their control will now described with reference to Figures 2 and 3. The support arm 36 has two identical support arm parts 78, each of which one side of the support member 34 arranged and by means of a pivot axis 80 are mounted on the support element 34. On both ends these support arm parts 78 are via bearing shafts 82, 82 'connected to each other, being on the first stock shaft 82 the follow roller 44 on one side of the support arm 36 and on the second bearing shaft 82 'on the other side of the Support arm 36, the two jaws 48, 50 of the bracket 12 are stored.

Das Lenkorgan 38 weist einen aus zwei gleich geformten Teilhebeln 84 bestehenden zweiarmigen Steuerhebel 84'auf, die ebenfalls je auf einer Seite des Tragelements 34 angeordnet und mittels einer weiteren Anlenkachse 80' an diesem gelagert sind. Die beiden Teilhebel 84 sind beiderends über weitere Lagerschäfte 86, 86' miteinander verbunden, wobei am weiteren Lagerschaft 86 die Steuerrolle 52 drehbar gelagert ist und an weiteren Lagerschaft 86' ein schaftartiges Verbindungsglied 88 einer Koppel 90 angelenkt ist. Das Verbindungsglied 88 ist in einem Koppelrohr 92 verschiebbar geführt, wobei zwischen dem dem Steuerhebel 84 zugewandtem Ende des Koppelrohres 92 und dem dem Steuerhebel 84' abgewandten Ende des Verbindungsgliedes 88 eine Druckfeder 94 wirkt. Die Relativverschiebung zwischen dem Koppelrohr 92 und dem Verbindungsglied 88 in Längsrichtung der Koppel 90 ist durch einen Begrenzungsstift 96 gegeben, der einen langlochartigen Durchlass 98 im Verbindungsglied 88 durchgreift und am Koppelrohr 92 befestigt ist. Unter normalen Betriebsbedingungen nimmt das Koppelrohr 92 bezüglich dem Verbindungsglied 88 die in den Figuren 2 und 3 gezeigte Lage ein, in welcher das steuerhebelseitige Ende des Querdurchlasses 98 am Begrenzungsstift 96 anliegt. The steering member 38 has one of two identically shaped ones Partial levers 84 on existing two-armed control levers 84 ', each also on one side of the support element 34 arranged and by means of a further articulation axis 80 ' this are stored. The two partial levers 84 are on both ends connected to one another via further bearing shafts 86, 86 ', the control roller 52 on the further bearing shaft 86 is rotatably mounted and on further bearing shaft 86 ' shaft-like connecting link 88 of a coupling 90 articulated is. The connector 88 is in a coupling tube 92 slidably guided, between which the control lever 84 facing end of the coupling tube 92 and the Control lever 84 'facing away from the end of the link 88 a compression spring 94 acts. The relative shift between the coupling tube 92 and the connecting member 88 in the longitudinal direction the coupling 90 is through a limiting pin 96 given an elongated hole-like passage 98 in the connecting member 88 passes through and attached to the coupling tube 92 is. Under normal operating conditions, the coupling pipe takes 92 with respect to the connecting link 88 shown in FIGS Figures 2 and 3 shown a position in which the control lever side End of the cross passage 98 on the limiting pin 96 is present.

Die erste Klemmbacke 48 besteht aus zwei miteinander drehfest verbundenen zungenartigen Klemmbackenteilen 48', die mittels eines Verbindungsstiftes 100 an eine Lasche 102 angelenkt sind, die andernends an das Koppelrohr 92 angelenkt ist.The first jaw 48 consists of two together non-rotatably connected tongue-like jaw parts 48 ', which by means of a connecting pin 100 to a tab 102 are articulated, the other to the coupling tube 92nd is articulated.

Die bezüglich der Drehachse 32 in radialer Richtung gesehen relativ zur ersten Klemmbacke 48 aussen liegende zweite Klemmbacke 50 ist plattenartig ausgebildet, weist am ihrem, in Umlaufrichtung U gesehen, vorlaufenden und über die Klemmbackenteile 48' der ersten Klemmbacke vorstehenden freien Ende eine Andrückwalze 104 auf und ist im Mittelbereich mit einem Mitnehmeranschlag 106 versehen, der das innere Ende des Klammermauls 46 bildet. Selbstverständlich weist der Mitnehmeranschlag 106 Ausnehmungen auf, die von den Klemmbackenteilen 48' durchgriffen sind um die Relativbewegung zwischen den Klemmbacken 48, 50 zulassen. Mittels eines parallel zum Lagerschaft 82' verlaufenden weiteren Verbindungsstifts 108 ist die zweite Klemmbacke 50 mit den beiden gleichgeformten dreieckförmigen Teilen 110 eines Anschlagelementes 110' verbunden, welche Teile zwischen den beiden Tragarmteilen 78 auf dem Lagerschaft 82' frei drehbar sitzen. Das Anschlagelement 110' ist dazu bestimmt, mit einem die beiden Tragarmteile 78 miteinander verbindenden Anschlagstift 112 zusammenzuwirken. Beim Anliegen des Anschlagelements 110' am Anschlagstift 112 befindet sich die zweite Klemmbacke 50 in einer Endstellung in welcher sie in etwa rechtwinklig zum zugeordneten Arm 40 des Tragarms 36 verläuft. Aus dieser Stellung kann die zweite Klemmbacke 50 nur im Gegenuhrzeigersinn bewegt werden; Figur 3.The with respect to the axis of rotation 32 in the radial direction seen relative to the first jaw 48 outside second jaw 50 is plate-shaped, has at its leading and seen in the direction of rotation U above the jaw parts 48 'of the first jaw free end of a pressure roller 104 and is in Provide a center stop with a driver stop 106, which forms the inner end of the clamp mouth 46. Of course the driver stop has 106 recesses which are penetrated by the jaw parts 48 ' about the relative movement between the jaws 48, 50 allow. By means of a running parallel to the bearing shaft 82 ' another connector pin 108 is the second Clamping jaw 50 with the two triangular shapes of the same shape Parts 110 of a stop element 110 'connected, which parts between the two support arm parts 78 on the The stock shaft 82 'is freely rotatable. The stop element 110 'is designed with one of the two support arm parts 78 interconnect stop pin 112 to cooperate. When the stop element 110 'is in contact with Stop pin 112 is the second jaw 50 in an end position in which they are approximately rectangular runs to the associated arm 40 of the support arm 36. Out this position, the second jaw 50 can only in Be moved counterclockwise; Figure 3.

Im Koppelrohr 92 ist eine eine Schliessfeder 114 für die Klemmbacken 48, 50 bildende Druckfeder angeordnet, die einerseits am klammerseitigen Ende des Koppelrohres 92 und andererseits an einer Zugstange 116 abgestützt ist, die im Innern des Koppelrohres 92 durch die Schliessfeder 114 hindurch verläuft und mittels eines Anlenkstifts 118 mit den Teilen 110 des Anschlagelements 110' verbunden ist. Die Schliessfeder 114 steht unter Vorspannung und wirkt einerseits über die Zugstange 116 auf die zweite Klemmbacke 50 und andererseits über die Lasche 102 auf die erste Klemmbacke 48 in Schliessrichtung ein. Die Kraft der Schliessfeder 114 ist kleiner als die Vorspannkraft der Druckfeder 94.In the coupling tube 92 there is a closing spring 114 for the Clamping jaws 48, 50 arranged compression spring, the on the one hand at the clamp-side end of the coupling tube 92 and on the other hand is supported on a pull rod 116 which in Inside the coupling tube 92 through the closing spring 114 runs through and with a pivot pin 118 with the parts 110 of the stop element 110 'is connected. The closing spring 114 is pretensioned and acts on the one hand via the pull rod 116 onto the second clamping jaw 50 and on the other hand via the tab 102 on the first jaw 48 in the closing direction. The power the closing spring 114 is less than the biasing force the compression spring 94.

Was soweit den Aufbau und die Funktionsweise der Klammer 12 und deren Steuerung betrifft, wird ausdrücklich auf die ältere EP-A-0 675 062 verwiesen.As far as the structure and functioning of the bracket 12 and its control, is expressly referred to older EP-A-0 675 062.

Am Anlenkstift 118 ist weiter eine Oeffnungslasche 120 angelenkt, die andernends mit einem Dreieckhebel 122 gelenkig verbunden ist, der über eine die beiden Tragarmteile 78 miteinander verbindenden Achse 124 am Tragarm 36 schwenkbar gelagert ist. Am Dreieckhebel 122 ist eine Oeffnungsrolle 126 frei drehbar gelagert, die dazu bestimmt ist, mit der Oeffnungskulisse 62 zusammenzuwirken. Wie dies in der Figur 3 strichpunktiert angedeutet ist, wird durch Zusammenwirken der Oeffnungsrolle 126 mit der am Steuerring 54 befestigten Oeffnungskulisse 62 die zweite Klemmbacke 50 entgegen der Kraft der Schliessfeder 114 von der ersten Klemmbacke 48 abgehoben, um die Klammer 12 zu öffnen. Durch die Anlenkung der zweiten Klemmbacke 50 über ein Gestänge an die Oeffnungsrolle 126 kann der Bewegungsraum für die Erzeugnisse 16' freigehalten werden.There is also an opening tab 120 on the pivot pin 118 articulated, the other with a triangular lever 122 is articulated, the one of the two support arm parts 78 connecting axis 124 on support arm 36 is pivotally mounted. At the triangle lever 122 is one Opening roller 126 freely rotatably mounted is intended to cooperate with the opening backdrop 62. As indicated by dash-dotted lines in FIG. 3 is by interaction of the opening roller 126 with the opening link 62 attached to the control ring 54 second jaw 50 against the force of the closing spring 114 lifted from the first jaw 48 to the clamp 12 to open. Through the articulation of the second jaw 50 via a linkage to the opening roller 126 Movement space for the products 16 'are kept free.

Die in den Figuren gezeigte Klammer 12 kann auf drei unterschiedliche Arten geöffnet werden:The bracket 12 shown in the figures can have three different types can be opened:

Erstens durch Einwirken der Oeffnungskulisse 62 auf die Oeffnungsrolle 126, wodurch die zweite Klemmbacke 50 im Gegenuhrzeigersinn verschwenkt wird, wie dies in der Figur 3 strichpunktiert angedeutet ist. Die Schwenklage der ersten Klemmbacke 48 ist durch die Steuereinrichtung 60 gegeben.First, by the action of the opening backdrop 62 on the Opening roller 126, whereby the second jaw 50 in Is pivoted counterclockwise, as in the figure 3 is indicated by dash-dotted lines. The swivel position of the first clamping jaw 48 is through the control device 60 given.

Zweitens. Wird die Klammer 12 durch Verschwenken des Steuerhebels 84' mittels der Steuereinrichtung 60 im Uhrzeigersinn verschwenkt und kommt dabei das Anschlagelement 110' am Anschlagstift 112 zur Anlage, ist beim gleichsinnigen weiteren Verschwenken der Klammer 12 die zweite Klemmbacke 50 am Folgen der Schwenkbewegung der ersten Klemmbacke 48 gehindert, sodass sich die beiden Klemmbacken 48, 50 ebenfalls voneinander abheben. Dies ist in der Figur 3 mit der gestrichelt gezeigten Schwenklage der ersten Klemmbacke 48 angedeutet.Secondly. If the bracket 12 by pivoting the Control lever 84 'by means of the control device 60 clockwise pivots and comes the stop element 110 'on the stop pin 112, is in the same direction further pivoting the bracket 12 the second Jaw 50 following the pivoting movement of the first Jaw 48 prevented, so that the two jaws 48, 50 also stand out from each other. This is in 3 with the pivot position shown in dashed lines first jaw 48 indicated.

Drittens, kann die Klammer 12 dadurch geöffnet werden, dass mit einem Wandelement 24 der Verarbeitungsmaschine 20 auf die Andrückwalze 104 und somit auf die zweite Klemmbacke 50 im Gegenuhrzeigersinn eingewirkt wird, wie dies ausführlich in der älteren EP-A-0 675 062 offenbart ist. Diese Betriebsart erlaubt das Andrücken der Erzeugnisse 16' an ein am Wandelement 24 anliegendes Druckereiprodukt 27.Third, the clip 12 can be opened that with a wall element 24 of the processing machine 20 on the pressure roller 104 and thus on the second clamping jaw 50 counter-clockwise, like this in detail in the older EP-A-0 675 062 is disclosed. This operating mode allows pressing the Products 16 'against a wall element 24 Print product 27.

Wie dies besonders der Figur 4 entnehmbar ist, werden die Klammern 12 bevor sie die Lieferstelle 14 erreichen auf die beschriebene zweite Art geöffnet um mit, in Umlaufrichtung U gesehen, nach vorne gerichtetem offenem Klammermaul 46 ein von einem Stapel mittels einer gestrichelt angedeuteten Saugkopfanordnung 128 abgehobenes Erzeugnis 16' bei dessen nachlaufender Kante, bei gefalteten Druckbogen 16 bei deren Falz 66 zu fassen. Dabei läuft die geöffnete Klammer 12 mit ihrem Mitnehmeranschlag 106 auf das Erzeugnis 16' auf und nimmt es in Umlaufrichtung U mit. Durch Verschwenken der ersten Klemmbacke 48 in Gegenuhrzeigersinn, wird die Klammer 12 geschlossen, wonach das Erzeugnis 16 im Klammermaul 46 festgehalten ist. Weiter ist der Figur 4 entnehmbar, dass beim Auflaufen der Klammer 12 auf das zu erfassende Erzeugnis 16' der Tragarm 36 mittels der Steuereinrichtung 60 entgegen der Umlaufrichtung U verschwenkt wird, was dazu führt, dass die Relativgeschwindigkeit zwischen der Klammer 12 und den zu erfassenden Erzeugnissen 16' reduziert ist gegenüber der Geschwindigkeit, die die Klammer 12 einnehmen würde, falls der Tragarm 36 bezüglich dem Trägerrad 28 seine Schwenklage beibehalten würde. Dieses Reduzieren der Geschwindigkeit ermöglicht eine schonende Behandlung der Erzeugnisse 16' und eine hohe Verarbeitungskapazität der Einrichtung. Bei geschlossenem Klammermaul 46 ist die Schwenklage der Klammer 12 durch die Steuereinrichtung 60 über das Lenkorgan 38 gegeben.As can be seen particularly in FIG. 4, the Brackets 12 before they reach delivery point 14 the described second type opened around with, in the direction of rotation U seen, open jaws facing forward 46 one of a stack with a dashed line indicated suction head assembly 128 lifted product 16 'at its trailing edge, with folded printed sheets 16 to take hold of their fold 66. The runs open bracket 12 with its driver stop 106 the product 16 'and takes it in the circumferential direction U With. By pivoting the first jaw 48 in Counterclockwise, the clip 12 is closed, after which the product 16 is held in the clamp mouth 46 is. It can also be seen from FIG. 4 that when it comes up the clip 12 on the product 16 'to be detected the support arm 36 counteracts by means of the control device 60 the direction of rotation U is pivoted, which leads to that the relative speed between the bracket 12 and the products 16 'to be detected is reduced versus the speed that the clip 12 is at would, if the support arm 36 with respect to the carrier wheel 28 would maintain its pivot position. This reducing the speed enables gentle treatment of products 16 'and high processing capacity the establishment. When the clamp mouth 46 is closed Pivot position of the clamp 12 by the control device 60 given via the steering member 38.

Die bezüglich dem nachlaufenden Falz 66 vorlaufende Kante 68 wird mittels eines Führungsblechs 130 geführt um die Druckbogen 16 am nach rückwärts Biegen infolge der Einwirkung des Fahrtwindes zu hindern. Nach der Uebernahme eines Druckbogens 16 werden die Tragarme 36 jeweils in Umlaufrichtung U verschwenkt, wonach die Einwirkung des Fahrtwindes auf die Erzeugnisse 16' vermindert ist.The leading edge with respect to the trailing fold 66 68 is guided around the by means of a guide plate 130 Sheet 16 on backward bending due to the action to prevent the wind from blowing. After the takeover a support sheet 16, the support arms 36 are each in Rotation direction U pivoted, after which the action of Driving wind on the products 16 'is reduced.

Anhand der Figur 5 wird nun das Oeffnen und anschliessende Ablegen der gefalteten Druckbogen 16 näher beschrieben. Das Oeffnungsaggregat 70 weist eine in Richtung des Pfeiles O drehend angetriebene Oeffnungswalze 132 auf, die mit einem Saugkopf 134 versehen ist, der über eine nicht gezeigte Ventilanordnung innerhalb eines bestimmten Drehbereichs der Oeffnungswalze 132 mit einer Unterdruckquelle verbunden ist. Der Saugkopf 134 ist dazu bestimmt, jeweils den dem Oeffnungsaggregat 70 zugewandten ersten Druckbogenteil 72 in einem dem Falz 66 gegenüberliegendem Randbereich zu fassen und festzuhalten bis jeweils ein Wandelement 24 der Verarbeitungsmaschine 20 zwischen die so voneinander abgehobenen Druckbogenteile 72, 74 eingefahren ist. Um das Erfassen des ersten Druckbogenteils 72 durch den Saugkopf 134 sicherzustellen, wird die vorauslaufende Kante 68 des ersten Druckbogenteils 72 mittels entlang einer geschlossenen Bewegungsbahn 136 umlaufend angetriebenen Nocken 138 geführt. Vorzugsweise sind die Nocken 138 an einer Kette angeordnet, die einerseits um die Achse der Oeffnungswalze 132 und andererseits um ein dieser vorgelagertes Umlenkrad 140 geführt ist. Derartige Oeffnungsaggregate 70 sind allgemein bekannt. Das Oeffnungsaggregat 70 ist am Maschinengestell 30 verstellbar angeordnet, um eine Anpassung an die zu verarbeitenden Erzeugnisse 16' zu ermöglichen. Um die vorlaufende Kante 68 der Druckbogen 16 zur Bewegungsbahn 136 der Nocken 138 zu leiten, ist ein weiteres Führungsblech 130' dem Oeffnungsaggregat 70 vorgelagert.With the help of FIG. 5, the opening and the subsequent one Placing the folded printed sheets 16 described in more detail. The opening unit 70 has one in the direction of Arrow O rotating driven opening roller 132, the is provided with a suction head 134, which does not have a shown valve arrangement within a certain range of rotation the opening roller 132 with a vacuum source connected is. The suction head 134 is intended to the first printed sheet part facing the opening unit 70 72 in one opposite the fold 66 Grip the border area and hold on to each Wall element 24 of the processing machine 20 between the thus lifted sheet parts 72, 74 retracted is. To capture the first sheet portion 72 ensure by the suction head 134, the leading Edge 68 of the first sheet part 72 by means of orbiting along a closed trajectory 136 driven cam 138 out. Preferably, the Cam 138 arranged on a chain on the one hand the axis of the opening roller 132 and the other one this upstream deflection wheel 140 is guided. Such Opening units 70 are generally known. The opening unit 70 is adjustable on the machine frame 30 arranged to adapt to the processed Allow products 16 '. Around the leading edge 68 the printed sheet 16 to the path of movement 136 of the cams 138 to guide, another guide plate 130 'the opening unit 70 upstream.

Wie dies der Figur 4 entnehmbar ist, werden die Klammern 12, bevor die vorlaufende Kante 68 der Druckbogen 16 jeweils das Oeffnungsaggregat 70 erreicht, durch Verschwenken des Tragarms 36 verzögert und dann wieder beschleunigt, um sicherzustellen, dass der erste Druckbogenteil 72 an einen Nocken 138 zur Anlage gelangt.As can be seen in FIG. 4, the brackets 12 before the leading edge 68 of the printing sheet 16 each reached the opening unit 70 by pivoting the support arm 36 delayed and then again accelerated to ensure that the first sheet part 72 comes to a cam 138 to the system.

Den Figuren 4 und 5 ist entnehmbar, dass in einem Anfangsabschnitt des Uebergabebereichs 18 die Tragarme 36 gleichgerichtet der Umlaufrichtung U gegen vorne und gleichzeitig die Klammern 12 über das Lenkorgan 38 in entgegengesetzter Richtung verschwenkt werden, so, dass im Uebergabebereich 18 das Klammermaul 46 im wesentlichen mit dem betreffenden Wandelement 24 fluchtet und auf dieses zu ausgerichtet ist. Im Endabschnitt des Uebergabebereichs 18 läuft nun die Oeffnungsrolle 126 auf die Oeffnungskulisse 62 auf, wodurch die Klammer 12 auf die weiter oben beschriebene erste Art geöffnet wird, um den Druckbogen 16 freizugeben. Dieser fällt nun rittlingsweise auf die Auflage 26. Nach dem Oeffnen der Klammer 12 wird der betreffende Tragarm 36 wieder entgegen der Umlaufrichtung U verschwenkt, um zu verhindern, dass die Klammer 12 mit der Verarbeitungsmaschine 20, bzw. den auf die Wandelemente 24 abgelegten Druckereiprodukte 27 und Druckbogen 16 in Berührung kommt.FIGS. 4 and 5 show that in an initial section of the transfer area 18, the support arms 36 rectified in the direction of rotation U towards the front and at the same time the clamps 12 via the steering member 38 in opposite direction are pivoted so that in Transfer area 18 essentially with the clamp mouth 46 aligns the relevant wall element 24 and towards it is aligned. In the end section of the transfer area 18 now the opening roller 126 runs on the opening backdrop 62, causing the bracket 12 to the one described above the first type is opened to the printing sheet 16 to release. This falls astride the edition 26. After opening the bracket 12, the relevant Support arm 36 again against the direction of rotation U pivoted to prevent the bracket 12 with the Processing machine 20, or that on the wall elements 24 stored printed products 27 and printed sheet 16 in Touch comes.

Figur 6 zeigt jeweils einen Teil des Oeffnungsaggregats 70, ein Wandelement 24 der Verarbeitungsmaschine 20 sowie eine einen aussermittig gefalteten Druckbogen 16 haltende Klammer 12. In der in der Figur 6 oben gezeigten Variante wird der Druckbogen 16 derart gehalten, dass der im Vergleich zum zweiten Druckbogenteil 74 kürzere erste Druckbogenteil 72 dem Oeffnungsaggregat 70 zugewandt und der zweite Druckbogenteil 74 der Drehachse 32 zugewandt ist. Der zweite Druckbogenteil 74 wird mit seiner vorlaufenden Kante 68 voraus zwischen das gezeigte Wandelement 24 und das diesem in Drehrichtung D vorlaufende Wandelement 24 eingeführt. Der erste Druckbogenteil 72 wird vom Saugkopf 134 gehalten und um die Oeffnungswalze 132 gebogen, während dem sich das Wandelement 24 unter der Oeffnungswalze 132 hindurch bewegt und am zweiten Druckbogenteil 74 zur Anlage kommt und diesen mitnimmt. Anschliessend wird der Saugkopf 134 gelüftet, wodurch nun die beiden Druckbogenteile 72, 74 das Wandelement 24 mit der Auflage 26 von oben umgreifen.Figure 6 shows a part of the opening assembly 70, a wall element 24 of the processing machine 20 and an eccentric folded sheet 16 holding Clip 12. In the variant shown in Figure 6 above the printed sheet 16 is held such that the im Compared to the second sheet part 74 shorter first Sheet part 72 facing the opening unit 70 and the second press sheet part 74 faces the axis of rotation 32 is. The second sheet part 74 is with its leading Edge 68 ahead between the wall element shown 24 and this leading wall element in the direction of rotation D. 24 introduced. The first sheet part 72 is from Suction head 134 held and around the opening roller 132nd bent during which the wall element 24 under the Opening roller 132 moved through and on the second sheet part 74 comes to the system and takes it with him. The suction head 134 is then released, which now the two sheet parts 72, 74 the wall element 24 with grasp the support 26 from above.

In der in der Figur 6 unten gezeigten Variante ist der Druckbogen 16 derart in der Klammer 12 gehalten, dass der dem Oeffnungsaggregat 70 zugewandte erste Druckbogenteil 72 über den der Drehachse 32 zugewandten zweiten Druckbogenteil 74 vorsteht. Wie dies mit dem Pfeil A angedeutet ist, ist in diesem Fall das Oeffnungsaggregat 70 im Vergleich zur oben gezeigten Variante entgegen der Drehrichtung D versetzt angeordnet. Dies stellt nun sicher, dass der längere erste Druckbogenteil 72 vom Saugkopf 134 erfasst werden kann, bevor er in die Bewegungsbahn der Wandelemente 24 vorsteht. Wie dies strichpunktiert angedeutet ist, kann sich dabei das Wandelement 24 unter der Oeffnungswalze 132 und dem um diese gebogenen ersten Druckbogenteil 72 vorbei bewegen, wonach der Saugkopf 134 gelüftet wird. Der erste Druckbogenteil 72 kommt somit an der Rückseite des Wandelements 24 zur Anlage, wogegen der zweite Druckbogenteil 74 nun mit seiner vorlaufenden Kante 68' voraus zwischen das Wandelement 24 und das diesem in Umlaufrichtung U vorlaufende Wandelement eingeführt wird, wie mit ausgezogenen Linien gezeigt. Die Druckbogenteile 72, 74 umgreifen somit wiederum von oben das Wandelement 24 mit der Auflage 26.In the variant shown below in FIG Sheet 16 held in the bracket 12 so that the the first printing sheet part facing the opening unit 70 72 via the second printed sheet part facing the axis of rotation 32 74 presides. As indicated by arrow A. in this case, the opening unit 70 is compared to the variant shown above against the direction of rotation D arranged offset. This now ensures that the longer first sheet portion 72 from the suction head 134 can be detected before entering the trajectory of the Wall elements 24 protrudes. How this is indicated by dash-dotted lines is, the wall element 24 under the Opening roller 132 and the first one bent around it Move the sheet part 72 past, after which the suction head 134 is aired. The first printed sheet part 72 thus arrives the back of the wall element 24 to the plant, whereas the second sheet part 74 now with its leading edge 68 'ahead between the wall element 24 and this in Direction of rotation U leading wall element is introduced, as shown with solid lines. The sheet parts 72, 74 thus again encompass the wall element from above 24 with the edition 26.

Dadurch, dass sowohl der Tragarm 36 als auch das Lenkorgan 38 unabhängig voneinander steuerbar sind und somit die Lage der Klammer 12 bezüglich dem Trägerrad 28 in erheblichem Masse verändert werden kann und die Position des Oeffnungsaggregates 70 einstellbar ist, können unterschiedlichst formatige und unterschiedlichst gefaltete Druckbogen 16 verarbeitet werden.The fact that both the support arm 36 and the steering member 38 can be controlled independently of one another and thus the Location of the bracket 12 with respect to the carrier wheel 28 in considerable Mass can be changed and the position of the Opening unit 70 is adjustable, can be varied format and differently folded Printing sheets 16 are processed.

Mit der oben beschriebenen Einrichtung können selbstverständlich auch Druckbogen 16 oder anderartige Erzeugnisse 16', wie Karten und dergleichen, in von benachbarten Wandelementen 24 gebildete taschenartige Aufnahmeteile 142 eingeführt werden. Wie dies anhand der Figur 5 einfach vorstellbar ist, ist dazu die Phasenlage zwischen der Verarbeitungsmaschine 20 und der Fördereinrichtung 10 um einen halben Takt zu verschieben und das Oeffnungsaggregat 70 ausser den Einwirkbereich auf die Erzeugnisse 16' zu bringen oder wenigstens den Saugkopf 134 dauernd von der Unterdruckquelle zu trennen.With the facility described above, of course also printed sheets 16 or other products 16 ', such as cards and the like, in from neighboring ones Wall elements 24 formed pocket-like receiving parts 142 be introduced. How this is easy with the help of FIG. 5 is conceivable is the phase relationship between the Processing machine 20 and the conveyor 10 um to move half a bar and the opening unit 70 except the area of influence on the products 16 ' bring or at least the suction head 134 constantly from the Separate vacuum source.

Auch können mit der Fördereinrichtung 10 Erzeugnisse 16' an die Wandelemente 24 oder an diesen anliegende Druckereiprodukte 27 zur Anlage gebracht und an diese angedrückt werden, wie dies in der älteren EP-A-0 675 062 ausführlich beschrieben ist. In diesem Fall entfaltet die Oeffnungskulisse 62 keine Wirkung. Sie ist deshalb wegnehmbar am Steuerring 54 befestigt. Es ist selbstverständlich auch denkbar, die Oeffnungskulisse 62 bewegbar anzuordnen und mittels eines Steuerelementes, beispielsweise eines Zylinderkolbenaggregates, in und ausser Arbeitsstellung zu verbringen.Products 16 'can also be on the wall elements 24 or on these printed products 27 brought to the system and pressed against it as in the older EP-A-0 675 062 is described in detail. In this case the opening backdrop 62 has no effect. she is therefore removably attached to the control ring 54. It is of course also conceivable, the opening backdrop 62 to be arranged movably and by means of a control element, for example a cylinder piston unit, in and to spend out of work position.

Es ist auch denkbar, die Klammern 12 zum Uebernehmen eines Erzeugnisses 16' mittels einer Oeffnungskulisse 62 zu öffnen. In diesem Fall kann auf den Anschlagstift 112 verzichtet werden.It is also conceivable to use the brackets 12 for one Product 16 'by means of an opening backdrop 62 to open. In this case, the stop pin 112 can be dispensed with will.

Es sei auch erwähnt, dass die Tragelemente 34 an einem endlosen Zugorgan, beispielsweise einer Kette, angeordnet sein können, das um Umlenkräder oder in einem Kanal geführt ist. Die Umlaufbahn der Tragelemente 34 kann somit beliebige Form aufweisen.It should also be mentioned that the support elements 34 on one endless traction element, for example a chain, arranged can be that led around pulleys or in a channel is. The orbit of the support elements 34 can thus have any shape.

In den Figuren ist eine trommelartig ausgebildete Verarbeitungsmaschine 20 gezeigt. Es ist aber auch möglich, dass die Wandelemente 24 an einem Rundlauf angeordnet sind, so, dass sie beispielsweise entlang einer langgestreckten Bewegungsbahn umlaufen.In the figures there is a drum-like processing machine 20 shown. But it is also possible that the wall elements 24 are arranged on a concentric run are such that they are, for example, along an elongated Orbit trajectory.

Der vollständigkeitshalber sei erwähnt, dass auch auf die Andrückwalze 104 oder ein gleichwirkendes Element verzichtet werden kann, falls mit der Fördereinrichtung 10 die Erzeugnisse 16' nicht gegen ein Wandelement 24 gedrückt werden sollen.For the sake of completeness it should be mentioned that also on the Pressure roller 104 or an equivalent element is dispensed with can be, if with the conveyor 10 Products 16 'are not pressed against a wall element 24 should be.
