Ein längenvariables Fü rungsschienenstück 1 weist im Querschnitt ein C-Profil zur Aufnahme einer Rollenkette 2 auf und besteht aus zwei getrennten Teilstücken 3; 4, von denen jedes drei einander gegenüberliegende sowie komplementär ineinandergreifende Segmente 6, 7, 8; 9, 10, 11 trägt.A variable-length guide rail piece 1 has a C-profile in cross section for receiving a roller chain 2 and consists of two separate sections 3; 4, each of which three mutually opposite and complementary interlocking segments 6, 7, 8; 9, 10, 11 carries.
Von den drei Segmenten 6, 7, 8 bzw. 9, 10, 11 liegt jeweils ein erstes Segment 6; 9 einem jeweils jenseits der Rolle 14 befindlichen zweiten und dritten Segment 7, 8 bzw. 10, 11 gegenüber.A first segment 6 is located from each of the three segments 6, 7, 8 and 9, 10, 11; 9 opposite a second and third segment 7, 8 and 10, 11 located beyond the roller 14, respectively.
Die Segmente 6, 7, 8 bzw. 9, 10, 11 der Teilstücke 3 bzw. 4 sind einander gleich, wenn ihr Querschnitt (Fig. 2) 180° um eine Rotat onsachse 13 der Rollen 14 der Rollenkette 2 gedreht wird.The segments 6, 7, 8 and 9, 10, 11 of the sections 3 and 4 are identical to one another if their cross section (Fig. 2) is rotated 180 ° about a rotation axis 13 of the rollers 14 of the roller chain 2.
Wenn die Rollen 14 der Rollenkette 2 z. B. von vier sich im rechten Winkel einander schneidenden Ebenen A; B; C; D begrenzt geführt werden, von denen jeweils zwei Ebenen A, B sowie C, D zueinander parallel verlaufen und zumindest zwei Ebenen A, B parallel zur Rotationsachse 13 der Rollen 14 verlaufen, so liegt von dem ersten Teilstück 3 das erste Segment 6 an der ersten oberen Ebene A an. Weiterhin liegt das zweite Segment 7 an der dritten linken vertikal verlaufenden Ebene C an, das dritte Segment 8 liegt an der vierten, rechten, vertikal verlaufenden Ebene D an und das zweite und dritte Segment 7 und 8 liegt an der zweiten unteren Ebene B an.If the rollers 14 of the roller chain 2 z. B. of four intersecting planes A at right angles; B; C; D are guided to a limited extent, of which two planes A, B and C, D each run parallel to one another and at least two planes A, B run parallel to the axis of rotation 13 of the rollers 14, the first segment 6 of the first section 3 lies on the first upper level A. Furthermore, the second segment 7 lies on the third left vertical plane C, the third segment 8 lies on the fourth right vertical plane D and the second and third segments 7 and 8 lie on the second lower plane B.
Die Segmente 9 bis 11 des zweiten Teilstückes 4 liegen an der Rolle 14 wie folgt an: das erste Segment 9 liegt an der zweiten unteren Ebene B an, das zweite Segment 10 liegt an der dritten, linken, vertikal verlaufenden Ebene C an, das dritte Segment 11 liegt an der vierten, rechten, vertikal verlaufenden Ebene D an, das zweite und dritte Segment 10 und 11 liegt jeweils an der ersten oberen Ebene A an.The segments 9 to 11 of the second section 4 are in contact with the roller 14 as follows: the first segment 9 is in contact with the second lower level B, the second segment 10 is in contact with the third, left, vertical plane C, the third Segment 11 lies on the fourth, right, vertical plane D, the second and third segments 10 and 11 each lie on the first upper plane A.
Somit ist in der zweiten, auseinandergezogenen Stellung (Fig. 1) gesichert, daß die Rollen 14 entweder von den Segmenten 6 bis 8 des ersten Teilstückes 3 oder von den Segmenten 9 bis 11 des zweiten Teilstückes 4 geführt werden. Eine Lauffläche für die Rollen 14 kann je nach Belastung der Rollenkette 2 in der Ebene B oder in der Ebene A oder teilweise in beiden Ebenen B; A liegen.It is thus ensured in the second, extended position (FIG. 1) that the rollers 14 are guided either by the segments 6 to 8 of the first section 3 or by the segments 9 to 11 of the second section 4. A running surface for the rollers 14 can, depending on the load on the roller chain 2, in level B or in level A or partially in both levels B; A lie.
Die Rollen 14 sind mittels innerer oder äußerer Laschen 18, 19 oder 21, 22 und Kettenbolzen 23 miteinander ve rbunden .The rollers 14 are by means of inner or outer tabs 18, 19 or 21, 22 and chain pin 23 connected together.
Ein Teilstück 3 oder 4 ist dann sei tenges t e l If est angeordnet, wenn eine Kettenführung längenvariabel ausgebildet werden muß. Beide Teilstücke 3 und 4 sind vorteilhaft dann in einem vorgewählten auseinandergezogenen Zustand sei t engest e l If est angeordnet, wenn z. B. starke Temperaturschwankungen Einfluß auf die Länge der Kettenführung haben, z. B. in Troc kenöf en .A section 3 or 4 is then tenges t e l If est arranged when a chain guide must be made variable in length. Both sections 3 and 4 are advantageously arranged in a preselected, pulled-apart state, if they are narrow, if z. B. strong temperature fluctuations affect the length of the chain guide, z. B. in Troc kenöf en.
Es ist aber auch möglich, beide Teilstücke 3; 4 zumindest gleitend im Seitengestell zu lagern, d. h. zu befestigen.But it is also possible to use both sections 3; 4 at least to slide in the side frame, d. H. to fix.
Nach einer zweiten Ausführungsvariante (Fig. 3 und 4) weist ein aus zwei Teilstücken 24; 26 bestehendes Führungsschienenstück 27 insgesamt fünf Segmente 28 bis 32 auf, von denen das erste Teilstück 24 zwei Segmente 28; 29 und das zweite Teilstück 26 drei Segmente 30; 31; 32 trägt, die komplementär ineinandergreifen.According to a second embodiment variant (FIGS. 3 and 4), one of two sections 24; 26 existing guide rail piece 27 a total of five segments 28 to 32, of which the first section 24 two segments 28; 29 and the second section 26 three segments 30; 31; 32 carries, which complement each other.
Die zwei Segmente 28; 29 des ersten Teilstückes 24 sind im Querschnitt gesehen (Fig. 4) oberhalb und unterhalb der Rolle 14 angeordnet, so daß daß erste Segment 28 an der ersten oberen Ebene A und das zweite Segment 29 an der zweiten unteren Ebene B und beide Segmente 28; 29 gemeinsam an der vierten, rechten, vertikalen Ebene D anl i egen.The two segments 28; 29 of the first section 24 are seen in cross section (FIG. 4) above and below the roller 14, so that the first segment 28 on the first upper level A and the second segment 29 on the second lower level B and both segments 28; 29 together on the fourth, right, vertical plane D issue.
Die drei Segmente 30; 31; 32 des zweiten Teilstückes 26 sind im Querschnitt gesehen so angeordnet, daß das erste Segment 30 oberhalb und das zweite Segment 31 unterhalb der Rolle 14 und das dritte Segment 32 in Richtung der Rotationsachse 13 der Rollen 14 und neben der Rolle 14 sowie zwischen den ersten und zweiten Segmenten 28; 29 des ersten Teilstückes 24 angeordnet ist. Dabei liegt das erste Segment 30 an der ersten oberen Ebene A und das zweite Segment 31 an der zweiten unteren Ebene B und beide Segmente 30; 31 liegen gemeinsam an der dritten, linken, vertikal verlaufenden Ebene C an. Das dritte Segment 32 ist ergänzend zwischen den Segmenten 28; 29 angeordnet .The three segments 30; 31; 32 of the second section 26 are seen in cross section so that the first segment 30 above and the second segment 31 below the roller 14 and the third segment 32 in the direction of the axis of rotation 13 of the rollers 14 and next to the roller 14 and between the first and second segments 28; 29 of the first section 24 is arranged. The first segment 30 lies on the first upper level A and the second segment 31 on the second lower level B and both segments 30; 31 lie together on the third, left, vertical plane C. The third segment 32 is in addition between the segments 28; 29 arranged.
Jeweils verschiedene Kettenbolzen 23 einer in einem ersten Seitengestell laufenden Rollenkette 2 können mittels Streben 34 (Fig. 4) mit g Lei chge Lage rten Kettenbolzen einer in einem zweiten Seitengestell laufenden zweiten Rollenkette verbunden sein.Different chain pins 23 of a roller chain 2 running in a first side frame can be connected by means of struts 34 (FIG. 4) with the same chain pins of a second roller chain running in a second side frame.
Dadurch kann für Bogenrotat i onsdruckmaschi nen ein Greiferwagen oder bei Rollenrotationsdruckmaschinen für das Einziehen einer besonders breiten Materialbahn ein sich über die gesamte Maschinenbreite erstreckender Wagen gebildet werden.As a result, a gripper carriage can be formed for sheet-fed rotary printing presses or, in the case of web-fed rotary printing presses, for drawing in a particularly wide material web, a carriage extending over the entire machine width can be formed.
Die Teilstücke 24; 26 nach der zweiten Ausf üh rungs a r i ant e (Fig. 3 und 4) können dahingehend modifiziert ausgebildet sein, daß das erste Segment 28 des ersten Teilstückes 24 sowie das erste Segment 30 des zweiten Teilstückes 26 jeweils gegenüber den Segmenten 29; 31; 32 eine größere Länge aufweisen.The sections 24; 26 after the second Execution ari ant e (Fig. 3 and 4) can be modified such that the first segment 28 of the first section 24 and the first segment 30 of the second section 26 each with respect to the segments 29; 31; 32 have a greater length.
Alternativ dazu können die Segmente 29; 31 der Teilstücke 24; 26 gegenüber den Segmenten 28; 30; 32 eine andere, z. B. größere Länge aufweisen. Dadurch entstehen in der zweiten, auseinandergezogenen Stellung der Teilstücke 24; 26 Lücken 36; 37, die nicht übereinander - wie in Fig. 3 dargestellt - sondern nebeneinander - nicht dargestellt - befindlich sind. Alternatively, the segments 29; 31 of the sections 24; 26 compared to the segments 28; 30; 32 another, e.g. B. have greater length. This results in the second, exploded position of the sections 24; 26 gaps 36; 37, which are not one above the other - as shown in Fig. 3 - but next to each other - not shown - are located.
