Monorail conveyor rail systems are formed from linear and / or arcuate profile rails ( 1 ) with preferably C-shaped cross sections that are open at the bottom and accommodate roller units ( 2 ), and switches ( 3 ) and crossings ( 4 ) are in these profile rails ( 1 ) ) installed, these points ( 3 ) and crossings ( 4 ) have shaped and arranged according to the lines of the drive-through sections, and cross-slidably guided switch and cross-sections ( 5/6 , 7/8 ).

For switching each switch ( 3 ) and crossing ( 4 ), a fixed bearing ( 9 or 10 ) of the profile rails ( 1 ) can be pivoted about an axis ( 11 ) and with the two switch and crossing sections ( 5/6 , 7/8 ) hinged overrun control part ( 12 ) is provided which protrudes into the track roller track of the profile rails ( 1 ) and through which the switch ( 3 ) or crossing ( 4 ) with a section ( 5/7 ) from one Drive-out route and with the other section ( 6/8 ) is mechanically shifted into the second drive-through route.

The casserole control part ( 12 ) is formed by a plate with an elongated elliptical shape or a kite-like shape, the two convex longitudinal edges ( 12 a ) of which form caster edges for the roller mechanisms ( 2 ).

The plate-shaped overrun control part ( 12 ) has a length end around a transverse and / or longitudinal connection in the form of a web or plate as a bearing ( 9/10 ) between two profile rails ( 1 ) at a distance from the switch or crossing sections ( 5/6 , 7/8 ) held axis ( 11 ) pivotally mounted in the longitudinal rail plane and with the other length end with a fork-shaped recess ( 13 ) to cut one between the points or crossing ( 5/6 , 7/8 ) fixed hinge pin ( 14 ) movably connected to the switch or crossing sections ( 5/6 , 7/8 ). A web ( 15 ) is fastened between the sections ( 5/6 , 7/8 ) for the mounting of the hinge pin ( 14 ).

The straight and the curved switch section ( 5/6 ) or the two straight crossing sections ( 7/8 ) running at an angle to one another are fastened to a sliding plate ( 16 ) which is arranged in a groove guide ( 17 ), such as a dovetail or T-groove, a switch or crossing camp ( 18 ) slidably.

The straight turnout section ( 5 ) and the curved turnout section ( 6 ) lie next to each other at a short distance and are attached together to the slide plate ( 16 ). The two crossing sections ( 7/8 ) each consist of a short, straight profile section and are at right angles to each other.

The two switch sections ( 5/6 ) formed by profile rail sections have a face directed at right angles to their longitudinal direction, the face of the curved switch section ( 6 ) correspondingly extending the course of the bend.

The two rectilinear intersection sections ( 7/8 ) have oblique end faces which are at an angle of 45 degrees to the longitudinal direction of the intersection sections ( 7/8 ).

The turnout and crossing portions (5/6, 7/8) with their end faces close to the two active positions flush with the adjoining rails (1), so that only between the profile rails (1) and the portions (5/6 , 7/8 ) there is a thin sliding gap.

The turnout and crossing sections ( 5/6 , 7/8 ) have shifting cross-stops ( 19 ) on the outside, which cooperate with the profile rails ( 1 ) in the respective turnout or crossing position and thus limit each passage.

Furthermore, on the turnout or crossing sections ( 5/6 , 7/8 ) bracket-like safety limits ( 20 ) are attached on the outside, which when switching from one passage to the other and in the respective switched position in front of the decommissioned rail passage and thus prevent the rollers of the roller mechanism ( 2 ) from running out of the inactive position rails ( 1 ), which also comes into play during the switchover.

Referring to FIG. 2, the switch (3) is in the bent position through driving route and the bent Weichenab section (6) connecting the two angle to each other extending profile rails (1).

The emergent control part (12) has been pivoted about the axis (11), the linear soft portion (5) is located outside the two aligned lying profile rails (1) and the run-up control part (12) covers a portion of the profile rail (1 ).

If the switch ( 3 ) is now to be switched over, a caster ( 2 ) in the profile rail ( 1 ) moves against the overrun control part ( 12 ), presses on the overrun edge ( 12 a ) and thereby causes the overrun control part to pivot ( 12 ) around the axis ( 11 ) and a simultaneous displacement of the switch ( 3 ) in the guide ( 16 , 17 , 18 ) via the hinge pin ( 14 ), whereby the straight switch section ( 5 ) between the aligned rails ( 1 ) in the rectilinear drive position as shown in FIG. 5 is shifted.

The changeover at the intersection ( 4 ) corresponds to the switchover, whereby the run-up control part ( 12 ) with a run-up edge ( 12 a ) is always in the area of a profile rail ( 1 ) and in each of the two drive-through route positions and by counter-travel of the caster ( 2 ) a pivoting of the overrun control part ( 12 ) about the axis ( 11 ) and thus a displacement of the two intersection sections ( 7/8 ) from one to the other in a straight line drive position.

In accordance with Fig. 9 a straight through route is shown by the crossing portion is pushed (8) aligned between two profile rails (1) and the other junction section (7) is located outside the second aligned profile rails (1) in the non-functional position.

Fig. 6 shows the two crossing sections ( 7/8 ) during the switching process in an intermediate position.

The overhead conveyor system shows a further embodiment of an intersection in the area of a sliding door or gate ( 21 ), which is shown in FIGS. 10 to 13. Here, the gate ( 21 ) with its track roller assemblies ( 2 ) is slidably guided in a continuous profile rail ( 1 ) and below this profile rail ( 1 ) there is a second, crossing profile rail ( 1 ) with a section ( 22 ) which can be moved out of the same.

This section rail section ( 22 ) is equipped with a safety strip ( 23 ) which locks behind the section rail ends ( 1 a ) in the retracted position.

To remove the profile rail section ( 22 ), the safety bar ( 23 ) is raised by an unlocking device ( 24 ) arranged on the gate ( 21 ) and then moved with the profile rail section ( 22 ), the safety bar ( 23 ) through slots ( 25 ) in the profile rail ends ( 1 a ) can be pushed through.

The profiled rail section ( 22 ) has a trapezoidal basic shape, that is to say its two longitudinal ends run obliquely towards one another and, corresponding to these oblique longitudinal ends, the ends of the profiled rails ( 1 ) accommodating the section ( 22 ) between them are also beveled (see FIG. 12), so that when the profiled rail section ( 22 ) is retracted into the profiled rails ( 1 ), a positive connection is established and thus there is an insertion limit.

On the shorter trapezoidal longitudinal side, the securing strip ( 23 ) is mounted in height-adjustable manner in height guides ( 26 ), such as guide brackets, and the securing strip ( 23 ) projects with both ends beyond the shorter trapezoidal longitudinal side.

The unlocking device (24) has a höhenverschwenkbares about a horizontal axis (27) casserole piece (28), a Hubsteg (29) is fixed to the motion rigidly secured, which engages in Höhenverschwenken of the winding member (28) under the fuse strip (23) and this so far raises that it can be pushed through the slots ( 25 ) of the profile rails ( 1 ).

Portion on the sliding gate (21) and the rails (22) each have a magnet (30) attached, which cooperate in pushing out of the profiled rail section (22) so that the shifted profile rails portion (22) is moved with the gate (21) .

In Fig. 10, the profile rail section ( 22 ) between the profile rails ( 1 ) is retracted and the safety bar ( 23 ) is lowered and grips on the outside behind the profile rail ends ( 1 a ), so that the profile rails ( 1 ) with the profile rail section ( 22 ) form a continuous passage.

If the gate ( 21 ) is now to be moved, then this existing drive-through distance must be interrupted and the gate ( 21 ) moves with its magnets ( 30 ) against the magnet ( 30 ) of the profiled rail section ( 22 ) and at the same time the ramp ( 28 ) moves with it its arcuate ramp edge ( 28 a ) against the profile section ( 22 ), whereby the ramp piece ( 28 ) about its axis ( 27 ) is pivoted in height and thereby the lifting web ( 29 ) is also pivoted upwards, engages under the safety bar ( 23 ) and this lifts in its guide ( 26 ) so that it reaches the area of the slots ( 25 ). The two magnets ( 30 ) establish a connection between the gate ( 21 ) and the profile rail section ( 22 ) and then the profile rail section ( 22 ) is pushed through the slots ( 25 ) of the profile rails ( 1 ) and out with the gate ( 21 ) the profile rails ( 1 ) pushed out, so that the gate ( 21 ) can be moved through the previous cross-direction of the gate displacement direction.

During this movement, the magnetic connec tion between the gate ( 21 ) and the rail section ( 22 ) is maintained and also the safety bar ( 23 ) by the unlocking device ( 24 ) in its raised position (see. Fig. 11 and 12).

If the drive-through section ( 1 , 22 ) is to be restored, then the gate ( 21 ) is pushed back, the profile rail section ( 22 ) travels between the profile rails ( 1 ) and its securing strip ( 23 ) through the slots ( 25 ) and then bumps the profile rail section ( 22 ) with its oblique end faces against the likewise oblique end faces of the profile rails ( 1 ) and the displacement movement of the profile rail section ( 22 ) is limited.

The gate ( 21 ) is pushed back further, thereby loosening the magnetic connection ( 30 ) and now the ramp piece ( 28 ) can pivot downwards about the axis ( 27 ), the lifting web ( 29 ) also pivoting downwards and the safety bar ( 23 ) releases, which then falls down in the guide ( 26 ) and locks itself behind the profile rails ( 1 ) on the outside, so that the drive-through distance ( 1 , 22 ) is secured for the monorails.

The lower profile rail ( 1 ), which can be interrupted by the extendable profile rail section ( 22 ), is held suspended by a spacer ( 31 ) under the continuous profile rail ( 1 ).

The axis ( 27 ) of the run-up piece ( 28 ) with the lifting web ( 29 ) is fixed by a bearing ( 32 ) on the end face of the gate.

Furthermore, a stop ( 33 ) which limits the swiveling movement of the ramp piece ( 28 ) with the lifting web ( 29 ) downward is fastened to the end of the gate, onto which the lifting web ( 29 ) is also attached when the gate ( 21 ) is moved from the profile rail ( 1 ) retracted section rail section ( 22 ) supports away.

When using tandem trolleys as track roller assemblies ( 2 ), it is possible in the area of each switch ( 3 ) to maneuver the tandem carriage with its two pairs of track rollers into and out of the switch ( 3 ), with the track roller pairs being threaded one after the other while observing the safety regulations or be led out so that the tandem wagon cannot fall down.

The switches ( 3 ) are then equipped without safety limits ( 20 ).
