Abstract

The invention relates to a system for securing the course of a cable routing device (1) for routing at least one cable between a first connector location at a fixed point, to which a lower run can be connected, and a second connector location which can be moved relative to said first connector location on a driver, to which an upper run can be connected. During movement, the upper run (14) runs above the lower run (13), to which it is connected via a movable deflecting curve (15). According to the invention, the system comprises a number of securing devices (21, 41, 61, 71) which are arranged along the movement path, with at least one locking body (30) which can be moved between a locked position and an unlocked position. At least one part of the locking body (30) is positioned above the movement path in the locked position, in order to limit the freedom of movement of the upper run (14) in the upward direction. In the unlocked position thereof, the locking body (30) has a position which differs from the locked position thereof, with the result that the deflecting curve (15) can move past said locking body (30).

Description

System for securing the course of a

Cable guide device and guide channel for this purpose

The invention relates to a system for securing an intended course or to avoid an undesirable course of a cable routing device, which is for dynamically guiding at least one line between a first connection point and a thereto

relatively movable second connection point is suitable. The routing device can in particular a

Energy supply chain. Typically, such leads

Wiring device several supply lines, such as cables for electrical power and / or

Signal supply and / or hoses for supplying liquid or gaseous equipment.

The cable guide device is usually along a travel in a longitudinal direction or linearly movable, between two connection points. It has a lower strand which can be connected to the first connection point and an upper strand which can be connected to the second connection point and which are interconnected via a movable deflection bend

are connected. In the method, the top strand runs above the bottom strand in many applications, e.g. in horizontal applications. The first connection point can be arranged at a base or a fixed point. The second connection point can be moved relative to one

Be arranged driver, in turn to a movable part of a machine is arranged, for example, to be supplied from the fixed point. The upper run is

usually the takeaway strand.

In normal operation or during normal operation of the cable routing device, the upper run is pulled or pushed by the driver in the direction of travel. Due to friction and inertia, the cable guiding device causes an opposing force to the movement and, depending on the length and weight, it is sometimes used. exposed to considerable tensile or compressive forces.

Especially because of the pressure forces, especially during high travel speeds and / or long travel distances, during operation, error conditions can occur. Especially for consumers moving at high speeds and thus high accelerations or decelerations, e.g. in portal robots or other

Automation systems, there are difficulties in the operation always to ensure the desired course.

It can also be used at lower speeds,

especially with long travels, by external disturbance, e.g. due to foreign bodies, to a course that deviates excessively from the proper course, to a leakage of the

Obertrums come out of a guide, etc. to breakage of the cable guide device.

Therefore, systems for monitoring the operation of the routing devices are already known. These systems are for early detection of an undesirable

Gradually, before the wiring systems can be damaged with the lines run therein, suitable.

Such monitoring systems describe e.g. the

Utility Model DE 20 2016 107 316 Ul and

DE 20 2016 107 317 U1 of the Applicant. These systems include at least one encoder, the course-dependent signal is passed to an evaluation unit. The evaluation unit compares the output with a predetermined one

Tolerance range to monitor if a fault condition, such as unwanted position or incorrect course, occurs.

So the machine can be stopped even before a

Damage arises. The error condition can then be corrected subsequently.

As another, other approach describes

DE 10 2012 111 545 A1 A system for securing the course of a horizontally arranged energy guiding chain, in which the trailing side of the driver moves laterally next to the stationary run. This system has a number of retaining clips, which by utilizing gravity in a

Locking position are moved in which they clasp or embrace one of the strands to prevent lateral movement in the direction of the other strand.

However, it is an object of the present invention to provide for the occurrence of particularly critical processes

Routing facilities in which the

taker side Trum above the lower strand moves, as possible to prevent or reduce excessive deviations from the intended course of the cable guide device at least. In order for maintenance and / or undesirable downtime of the system can be at least reduced or possibly avoided. In this case, an undesirable chain course should be prevented as far as possible.

As a solution to the above problem proposes the

The present invention provides a system having the features of claim 1 and, independently thereof, a guide trough having the features of claim 20. advantageous

Embodiments of the system and the guide channel are the subject of the dependent claims. The system is for securing the course of a cable routing device, in particular one

Energy supply chain, trained. The

Cable guide device is suitable for guiding

at least one line, e.g. a cable, hose or the like, in a longitudinal direction of

Wiring device between a first

Junction at a fixed point and one to

relatively movable second connection point on one

Carrier, wherein the line guide device in an operating position connectable to the first connection point and a bottom strand with the second

Connection point has connectable upper run. Of the

Untertrum and the upper run are connected via a movable deflection arc. The

Cable guide device is along a linear

Travel traversable, in particular with a predominantly horizontal component or approximately horizontally. The travel path preferably runs along a horizontal. At the

Procedure runs the upper strand above the lower strand.

According to the invention the object is already achieved in that the system has at least one securing device with at least one locking body. The system may in particular comprise a number of securing devices each having at least one locking body, wherein the

Safety devices along the travel of the

Cable guide device are arranged. The or each locking body is movable between a locking position and an unlocking position. In the locked position is

at least a part of the blocking body above the

Traverse path or the nominal position of the upper run so

positioned so that limiting the freedom of movement of the upper strand is effected upwards. The locking body in its locked position is thus capable of an undesirable

Deviation of the upper run from a nominal course upward to limit. The locking body takes in his

Unlocking a position deviating from its locking position, so that the deflecting bow can pass unhindered or without impairment on this locking body.

The locking body in its locked position can one

counteract undesirable removal of the upper run farther away from the lower run. Accordingly, it is sufficient if only the upper strand of the at least one or more

Locking bodies are assigned.

As deflecting a properly curved

Longitudinal section of a cable guide means, within which the orientation or the course of the

Cable guide device is deflected and adheres to a predetermined radius. The

Cable guide device is in the deflection arc to a

Axis which is perpendicular to the longitudinal direction and preferably perpendicular to the vertical, bent.

The upper run and the lower run in particular each spaced from each other in the vertical direction, with the moving upper run above the resting lower run, in particular parallel to a vertical plane. A

Support surface of the lower run is spaced from a support surface of the upper run in the vertical direction.

Preferably, each blocking body cooperates with the upper side of the upper run, at least in the event of a failure, with the upper side forming the outer side of the energy guiding chain with respect to the deflection bend or representing the side of the upper run facing away from the lower run.

In case of deviating the upper run of his

Nominalverlauf upwards thus the upper run can come into contact with the part of at least one locking body, which positions in the locking position above the upper run is. The upper run comes in this case to stop with a blocking surface of the locking body, ie with a

Surface of the locking body, which faces in the blocking position of the cable guide device. This blocking surface is thus in particular in the blocking position of a

Plating surface of the lower strand and / or a top of the upper strand facing. Another departure from

Nominal course upwards can be easily and safely limited. Preferably, in the locked position, the locking body can not be unlocked by a force directed predominantly perpendicular to the longitudinal direction of the upper run in the vertical direction, i. not even by a section of the upper run moving in this direction.

It is possible depending on the application and design of the blocking body only a few security devices

provided. Especially when arranged in the most critical

Range and / or short guide length and / or sufficient longitudinal extension of the locking body may possibly only a single securing device sufficient to a

to avoid undesirable course.

As tests at high speeds show, an undesirable behavior typically occurs approximately in the first third side of the upper runner side, in the direction of thrust in front of the deflection bend. Therefore it can basically

Be sufficient, only this longitudinal region of the travel with few or possibly only one invention

To equip safety device.

The system according to the invention offers a number of advantages compared to systems which are designed only for monitoring the operation of cable routing devices. The system according to the invention is designed to counteract a possible deviation from the intended nominal course and to serve for an actual limitation of deviation. This is a particularly safe Operation possible even at very high speeds.

In addition, the system is particularly flexible. A limiting device in the form of a canopy above a region of the upper run would be conceivable, but would provide access to the roofed area of the

Complicate cable routing device. In which

System according to the invention is the access to

Cable guide device is not affected, what u.a. Assembly, inspection and maintenance simplified. The

Freedom of movement upwards is still limited, so that undesirable course is largely avoided.

The system according to the invention is particularly advantageous for so-called "sliding applications", ie applications in which the upper strand lays down on the lower strand during the process, as is usual with long travel paths as a so-called roller chain with rollers on a part of

Chain straps is executed. A deflection arc comprises two sections in the sliding applications: a first arcuate section within which the

Cable guide device about an axis perpendicular to

Is bent longitudinally, so that the extending direction of the wire guide device on both sides of the portion in opposite directions, and a second arcuate portion which merges in the other pivoting direction, possibly with a relation to the first portion rearward bending, to the upper strand. In sliding applications, the locking bodies in the locked position could interfere with the deflection arc process. However, the locking bodies according to the invention are designed to be movable and can be moved to an unlocking position to allow the process of the deflection arc past the respective locking body. When moving the upper run in a first direction, the first moves first Section of the Umlenkbogens past a locking device, and when moving in the opposite direction first moves the second portion of the deflection arc at this

Locking device over.

The securing devices are preferably arranged so that they can interact with these two sections of the deflection arc _Z , in particular above the lower strand, but below the apex of the

Deflection arc. Preferably, there is a nominal vertical distance between the top of the upper run and the

Blocking surface of the respective blocking body. A

Stop effect or an effective limitation should only occur in case of undesired deviations, d. H . preferably not in normal operation or normal operation.

Each securing device preferably has its own mechanical bearing, by means of which the movement of the blocking body or bodies is predetermined. Thus, in this embodiment, each securing device can be actuated individually. The mechanical support may be in particular in the form of a linear guide, e.g. as a linear sliding bearing, transversely to the longitudinal direction of the cable guide device, and in particular transversely to the vertical, be executed.

Each blocking body preferably has two opposite contact surfaces corresponding to each

passing by deflecting bow _Z to the

respective blocking body from the locking position in the

To move unlock position. The run-up surfaces may be formed in particular as run-on slopes. At the

Method of routing device in a first direction comes in this embodiment, the deflection arc in contact with a first contact surface of a locking body, which is moved due to the tapered shape of the contact surface by the deflection arc in the unlocked position,

especially in the direction transverse to the longitudinal direction and transversely to Vertical. In a method of

Cable guide device the opposite direction comes the deflection arc in contact with a second

Starting surface of this locking body, which in turn is moved due to the tapered shape of the contact surface by the Umlenkbogen in the unlocked position of the locking body. Thus, the deflecting bend can pass in both directions on a blocking body and if necessary actuate it directly.

In one embodiment, at least some include

Locking body in each case at least one roller, which in the

Locking position a rolling of the upper run at the respective

Locking body allows, if the upper strand should come into contact with the locking body. Each roller may in particular be rotatably mounted on an axis which is arranged perpendicular to the travel path. A circumferential surface of the roller can serve as a blocking surface. If the upper strand should move upwards from normal, the

Obertrum reach the roller (s) and can roll below the blocking surface of the locking body.

In one embodiment, each securing device in each case has a housing in which an associated blocking body is received in a longitudinally displaceable manner, in particular in the direction transverse to the longitudinal direction and transversely to the vertical. Of the

Locking body is mounted in the housing. The housing protects u.a. storage against contamination to reduce maintenance.

In another embodiment, each includes

Securing device at least one L-shaped bracket as a locking body which is pivotally mounted, so that in the locked position, a leg of the clip above the

Travel path of the cable guide device, in particular perpendicular to the longitudinal direction, is positioned and the

Locked area provides. In the unlock position, the clip may be pivoted to the side or pivoted so that no part of the staple is above the procedural path or so that an area above the plane in which moves the top of the upper run, is released and the

Can pass baffle. In particular, such a securing device may comprise an L-shaped bracket on both sides of the travel path, so that the cable guide is held on both sides if it should come into abutment with the blocking body. This avoids uneven

Stress and allows a common mechanical

Storage and / or joint operation. The clamp can pivot about an axis parallel to the axis

Lengthwise runs, be stored.

Regardless of the design, each securing device may have a pair of two oppositely movable locking bodies to secure the cable routing from two sides.

In one embodiment, each securing device comprises at least one rotatable locking roller, which acts as a locking body, and between the locking position and the

Unlocking position is slidably mounted, in particular transversely to the traversing plane of the cable guide device. With rollers, unwinding of the routing device outside of the nominal path can be effected, e.g. if unwanted deviations occur more frequently due to the application.

In one embodiment, each securing device has a controllable drive, such as an electric servomotor, stepping motor, linear motor, a pneumatic lifting drive or the like. , For adjusting the locking body between the locking position and the

Unlock. This embodiment reduces wear and is advantageous when impact noise should be avoided.

The blocking bodies can also be designed so that they can be moved from the locked position to the unlocked position by mechanical action of the passing deflection arc.

Each safety device can be used for automatic

Resetting the locking body from the unlocked position to the locking position have a return spring. A

Return spring can be combined with a controllable drive, but can do without such a drive. The

Return spring may be in or on the housing

Be arranged securing device.

In one embodiment, the system comprises at least one sensor device for detecting the position of at least one section of the cable guide device with respect to the travel path along the longitudinal direction. Sensor devices can operate without contact. In particular, the sensor devices can form a recognition path along the travel path. A sensor device may e.g. detect the position of the deflection arc. Alternatively, a sensor device can detect the position of the movable end of the wire guide device. In particular, a sensor device can detect a change in the direction of travel of the movable end of the cable guide device.

In particular, the system may include a control unit for controlling the drives based on a signal from the at least one sensor device. The control unit can determine the current position of the deflection arc, in particular based on information about the position of the movable end of the routing device.

The securing devices can be distributed along the entire travel path. However, in other embodiments, the securing devices may be arranged exclusively or increasingly along a more susceptible part of the travel, for example, the above-mentioned end first third.

The securing devices can be distributed regularly, in particular evenly, or else, for example. in increasing distance from each other according to decreasing reaction forces.

Particularly preferably, the securing devices are arranged at a distance from each other which is smaller than 6 times the amount of the Umlenkbogen radius, in particular less than or equal to twice the amount of Umlenkbogen radius.

Each locking body may each have at least one start roller, which cooperates with the deflection arc to the respective locking body from the locking position in the

To move unlock position. The rollers can be attached to the

Be arranged contact surfaces. Run-up rollers reduce the wear of the locking body and cable routing device.

Particularly preferably, the blocking bodies are arranged on both sides along the travel path. In particular, the

Locking body be arranged symmetrically on both sides along the travel path, with an axis of symmetry, which runs along the longitudinal direction of the travel path.

The routing device can as

Energy supply chain to be formed, in particular with two parallel and connected by transverse webs tabs forming a receiving space for the at least one line, each tab strand a plurality in

Has longitudinally adjacent side flaps, which are pivotally connected by a hinge connection.

Such power drag chains typically include hinged chain links each having two opposite side flaps. Each side flap can have two broad sides and two narrow sides. At each side flap, one of the narrow sides of a support surface of the lower strand and facing the opposite narrow side of the blocking surface.

In one embodiment, the upper run is designed to slide on the lower run. The securing devices are in this case preferably positioned in a vertical direction such that the blocking bodies, in particular the

Locking surfaces of the locking body, are in the blocking position at a height based on a support surface of the lower run, which is smaller than 2 times the radius of the bend radius and greater than 2 times the height of a strand of the

Energy supply chain is.

Preferably, the securing devices are in one

Horizontal direction is positioned so that the locking body both tabs against unwanted deviation of the

Secure upper run up. Such an embodiment is the effect of possible torsional stress of

Energy supply chain. The restricted areas of

Locking bodies may in this case in particular face the narrow sides of the side flaps on the upper side of the upper run, which faces away from the lower run or the bearing surface of the lower run.

The invention further relates to a guide trough for a typical energy guiding chain, which is used to guide at least one line, such as e.g. a cable, hose or

the like, between a first connection point to

Connection to a base, and a relatively movable second connection point for connection to a driver, is formed and thereby forms two strands, which are interconnected via a movable deflection arc. The guide trough has two opposite side walls which extend in a longitudinal direction and between which at least one of the chain strands can be received. According to the invention, the guide trough has a number

Safety devices, which are arranged along the guide groove at least on a side wall, each of these safety devices comprises a movable locking body and a controllable drive, such as an electric servomotor, stepper motor, linear motor, a pneumatic lifting drive or the like. for moving the locking body between a locking position, in which at least a part of the locking body of a side wall of the

Guide groove protrudes toward the other side wall, to prevent the escape of at least one strand from the

Locking guide groove transversely to the longitudinal direction, and an unlocking position in which the locking body has a position deviating from the locking position, so that the

Umlenkbogen can drive past this lock body.

In one embodiment, a number of sensor devices are arranged for detecting the position of at least a portion of the longitudinal direction on the guide trough, wherein the drives of the securing devices are controllable based on the signals of the sensor devices. Sensor devices can operate without contact. In particular, the sensor devices may comprise a detection path along the

Form the travel path. At least one sensor device can detect the position of the deflection arc. Alternatively, a sensor device may detect the position of the movable end of the energy guiding chain.

The above-described possible embodiments and

Arrangements of the locking bodies, the sensor devices, etc. can be combined with the features of the guide trough.

Energy guiding chain for a system according to FIG

perspective view.

FIG. 1 schematically shows a cable guide device, here by the example of an energy guide chain 1

Energy guiding chain 1 is connected to a stationary end 11 at a base and with a movable end 12 on a relatively movable to the base driver and leads between unspecified lines shown. The lines supply e.g. a moving machine part from the base with power or process media. The base (not

shown here) is a benchmark here. The driver (not shown) is connected to the machine part and moves with it relative to the base, e.g. in a

horizontal translational movement back and forth between two end positions A and B.

The energy chain 1 forms three longitudinal sections:

a bottom strand 13, an upper strand 14, and a

movable deflecting bow 15 which connects the lower run 13 and the upper run 14 with each other. The lower strand 13 is formed by a region between the stationary end 11 and the deflecting bend 15. The upper strand 14 is formed by a region between the deflecting bend 15 and the movable end 12. During operation, the driver moves along with the moving part of the machine along the travel and pulls the movable end 12 with the

Upper strand 14 in the direction from A to B (tensile force) or pushes the upper strand 14 in the direction of B to A

(Thrust). As the length of the upper run 14 decreases in the direction from A to B or B to A, the reaction force in the energy guiding chain 1 decreases. In the method, the upper run 14 runs in the illustrated embodiment, approximately horizontally and partially sliding on the lower run 13 along a linear travel path. The upper strand 14 slides or rolls on the lower strand 13 from. The deflecting bow 15 is a curved longitudinal section of the energy guiding chain 1, within which the energy guiding chain 1 a bend about an axis perpendicular to the longitudinal direction of the

Traversing runs, has, so that the course of the

Energy guiding chain 1 is reversed by about 180 °. in the

Deflector 15 holds the power transmission chain 1 a

predetermined bending radius, so that the guided

Lines are protected against mechanical stress. The travel does not necessarily have to be horizontal.

FIG. 9 shows purely by way of example a longitudinal section of a known energy guiding chain 1 with two

Tabs 90 arranged parallel to each other and spaced in the transverse direction. The

Tab straps 90 are interconnected by transverse webs 92 and form a guided-utility containment space 93 (not shown). Each tab strand 90 is of a plurality in the longitudinal direction, i. in

Longitudinal direction of the guided supply lines,

successive side flaps 94 constructed. each

The side flap 94 has a plate-like construction and has two broad sides 96, which form overlapping areas, and two narrow sides 98. Two successive each

Side flaps 94 overlap with corresponding ones

Overlap areas of broadsides 96 and their

Longitudinal ends and are pivotally connected together by a hinge connection 99. It can be cranked side flaps or, as shown in FIG.9, alternating indoor and

Outer tabs are used as side flaps 94. FIG. 9 shows a specific example of an energy guiding chain 1 with rollers for unrolling the upper strand on the upper strand.

FIG.l and FIG.2A-2C show schematically a system for

Securing the course of the energy chain 1, which consists essentially of securing devices 21. The securing devices 21 are along the travel path arranged. In the illustrated embodiment, the securing devices 21 are distributed uniformly and on both sides along the entire travel path. The distance in the longitudinal direction between each two consecutive securing devices 21 here corresponds approximately to the

Radius of the deflection arc 15. The distance may possibly also be uneven, e.g. increasingly from B to A in function of decreasing thrust in the upper strand 14. The

Securing devices 21 may be e.g. as FIG.2A-C show, in pairs opposite symmetrical to the travel or possibly offset in the longitudinal direction.

FIGS. 2A-2C show the system according to FIG. 1 in different partial views. The securing devices 21 each comprise a blocking body 30. In the example shown here, the blocking bodies 30 are arranged in a horizontal plane extending above the upper run 14 (FIG. 2A). The blocking bodies 30 are displaceable between a blocking position and an unlocking position transversely to the longitudinal direction of the travel path (FIG. 2B). In the blocking position, a part of the respective blocking body 30 extends vertically above the movement range in which the upper run 14 moves around the upper side 141 of the upper run 14, or the side which faces away from the lower run 13 (see FIG. to overlap (viewed in plan view).

In a normal operating condition, the upper run 14 runs as intended below the blocking body 30. If the upper run 14 should deviate excessively from the normal travel, it comes to a stop with a

underside provided blocking surface 301 of the respective blocking body 30, which faces the upper strand 14, and may e.g. with the top 141 slide off it. Thus, a further deviation of the upper strand 14 from the normal

Moving up prevented without stopping the movement of the driver. The blocking area can be with a roll Be provided (not shown), so that the upper strand 14 can roll if necessary.

The arrangement of the securing devices 21 is

preferably chosen so that in the locked position, a vertical distance between the top 141 of the upper strand

14 and the blocking surfaces 301 of the locking body 30 is present, so that the upper strand 14 in normal operation not to the

Locking bodies 30 rubs. This distance can be minimized or even omitted, especially if the blocking surfaces are designed with rollers.

The deflection arc 15 has a certain vertical extent due to the predetermined bending radius. For safety reasons, the course of the upper run 14 should not exceed a certain limit height H, which is generally clear

below the peak height or the height S of the

Umlenkbogens 15 is located. The upper side 141 of the upper run 14 moves in the nominal course on a plane which is at or below the limit height H. Accordingly, the height of the plane of action of the blocking bodies 30, i. the distance of the locking surface 301 of the support surface 131 of the lower run 13, selected. The blocking bodies 30, which the deflection bend 15 approaches, are displaced into an unlocking position, so that the respective blocking body 30 is the method of the deflection bend

15 not blocked or the deflecting 15 at this

Lock body 30 can pass. After the deflecting bow 15 has passed, this blocking body 30 is moved back into the blocking position.

In the partial views FIGS. 2A-2C are exemplary

Snapshot corresponding to the position of the Umlenkbogens 15, the two outer pairs of the locking body 30 in the locked position, and the three central pairs of the locking body 30 in

Unlock position shown.

FIGS. 3A-3B show a securing device 21 according to FIGS FIGS. 2A-2C in perspective from below. The

Safety device 21 according to this embodiment comprises a cuboid housing 32. In each housing 32, a respective blocking body 30 is received and

longitudinally displaceable e.g. by means of a linear guide

stored. The locking body 30 has the shape of a locking bar or a pawl with two in the front part

bevelled forwardly tapered side surfaces 302, which as start-up surfaces or chamfers at horizontal

Serving impinges, and a lower surface (FIG.3B), which serves as a vertically blocking blocking surface 301 for locking transversely to the directions of contact. In the unlock position

(FIG.3A), the front part of the locking body 30 with the blocking surface 301 is located largely inside the

Housing 32. In the locked position (FIG.3B) is the

Lock body 30 extended out of the housing 32, so that the blocking surface 301 from the housing 32 vorseht, or the

Locking surface 301 is ready for locking or locking. The locking body 30 acts, e.g. unlike a door latch, against forces in the direction perpendicular to the blocking surface 301 always blocking and releasing only when force in a direction transverse thereto (start-up direction). The housings 32 serve as a guide and for mounting the locking bodies 30 and are arranged so that the housings 32 the method of

Deflection bow 15 do not disturb, but in the blocking position, the locking body 30 are located above the travel. The housing 32 is aligned and mounted with respect to the energy guiding chain 1 such that the blocking bodies 30

perpendicular to the longitudinal direction, in FIGS. 2A-2C, e.g. horizontal.

In FIG.2A-2C, the locking body 30 by a mechanical action of the passing Umlenkbogens 15 in the

Unlock position adjustable. That is, the chamfers 302 cooperate with the passing deflecting bend 15 to move the locking body 30 from the locked position into the Unlock to move position in which the locking body 30 is moved into the interior of the housing 32. In further (not shown) embodiments, the run-on slopes 302 are provided with run-in rollers, so that the deflecting bow 15 during the displacement of the locking body 30 in the

Unroll unlock position on the runners.

FIG. 4A shows a securing device 21 that is intended for

Adjusting the locking body 30 from an unlocked position back into the locking position with a return spring 33 is equipped. In this adjustment comes the

Lock body 30 at a retaining edge 321 of the housing 32 for abutment.

FIG.4B shows a securing device 41 with a

controllable drive 34, e.g. a linear drive or the like. , For adjusting the locking body 30 from the locked position to the unlocked position. The linear actuator 34 is operatively connected via a transmission with freewheel with the locking body 30 and adjusts the locking body 30 in the unlocked position, even before the locking body 30 in contact with the

passing deflector 15 comes - so can the

Dodge lock body 30 before this contact.

The securing device 41 according to FIG. 4B

illustrated embodiment, in addition to the drive 34 also comprises a return spring 33 for automatically resetting the locking body 30 from the unlocked position (see FIG.3A) in the locked position (see FIG.3B). One

Adjusting the blocking body 30 back into the blocking position is therefore also possible passively without the drive 34.

FIG.5A-5B show partial views of the system with the

The function of the locking bodies in the securing devices 61 according to FIGS. 6A-6B respectively meet two opposing L-shaped brackets 306, which are pivotably mounted on a frame 320. In the locked position, a short leg of each bracket 306 extends above the travel path perpendicular to the longitudinal direction of the travel and provides a blocking surface 311. The blocking surface 311 extends just above the plane in which the upper side 141 of the upper run 14 moves. In the unlock position, the clamp 306 is pivoted to the side, so that the deflecting bend 15 can pass. The mutually pivotable mounting of the brackets 306 each have an axis parallel to the

Traversing direction runs. In FIG.6B, both brackets 306 are in the lock position, as well as on both sides

seen pivoted brackets 306 in unlock position.

are arranged. The axes of rotation of the locking rollers 307 are aligned perpendicular to the traversing plane. The height or here horizontal plane on which the axes of rotation are relative to the support surface 131 of the lower run 13, is greater than the at least by a radius of the locking rollers 307

Removal of the top 141 of the upper run 14 of the support surface 131 of the lower run 13, possibly plus game so that the barrier roller 307 are initially unloaded. Each barrier roll 307 is slidable parallel to its respective axis of rotation and may be e.g. be moved by a linear drive (not shown) between the lock position and the unlock position. Each barrier roll 307 may be e.g. be mounted on a pivot both rotatable and displaceable. The circumferential rolling surface of the locking rollers 307 serves as a blocking surface. In a deviation of the upper run 14 from the normal travel up the upper run 14 can roll on the locking rollers 307 so.
