Definitions
- the present invention relates to a monorail for the transport of heavy loads such as truck frame components, truck T railers or the like.
- a monorail system has guided passive drives on rails for receiving a heavy load.
- At least two passive drives are connected via a crossbar to a passive vehicle.
- the load spreader is designed to accommodate a heavy load, extends substantially along the conveying direction and is mounted below the passive drives.
- the monorail further has at least one stationary drive device for initiating a propulsion force on the passive vehicle.
- the drive device has a Reibrad- Gegenrad arrangement and a contact pressure device.
- the friction wheel is arranged for transmitting the propulsive forces on the load traverse on one side of the load crossmember.
- the mating gear is arranged transversely to the conveying direction on one of the first side of the load cross-member opposite side for transmission and / or for receiving a transverse force transmitted to the load cross member.
- a contact force is exerted in the direction of the load cross-member via the mating gear and / or via the friction wheel.
- the corresponding monorail should have a simple construction that provides high stability and reliability.
- the overhead conveyor according to the invention for the transport of heavy loads such as truck frame components, truck T railers or similar includes guided on rails passive drives to accommodate the heavy load, at least two passive drives are connected via a crossbar to a passive vehicle and the load crossbar to accommodate the heavy load is designed to extend substantially along the conveying direction, below the Passive drives is mounted and at least one stationary drive means for initiating a propulsion power on the passive vehicle, wherein the drive means comprises a friction wheel-Gegenrad arrangement and a pressing device, wherein the friction wheel for transmitting the propulsive forces on the load traverse on one side of the load crossmember is arranged and the mating is arranged transversely to the conveying direction on one of the first side of the load cross-member opposite side for transmitting and / or receiving a transmitted to the load traverse transverse force, wherein by means of the pressing device via the counter gear and / or via the friction wheel, a contact force is exerted in the direction of the load traverse.
- the drive means comprises a friction wheel-G
- the drive device has a pretensioning device which is designed to impart an additional pretensioning force to the contact pressure device.
- the additional biasing device can thus be adjusted in a simple manner, the force exerted by the friction wheel-mating gear arrangement on the load cross-drive force and in particular kept constant.
- the above-mentioned wear effects can be compensated by increasing or decreasing the biasing force.
- the biasing means is controlled by hydraulic, electrical and / or pneumatic means.
- one or the other means may preferably be used.
- Common to the means is a remote controllability of the pretensioner. This is accompanied at the same time by a certain degree of automation of the pretensioning device.
- the biasing means is adapted to compensate for a variable distance between the load spreader and the friction wheel.
- the compensation of the variable distance can be done, for example, during a passage of the spreader on the friction wheel-counter-wheel assembly. This means that such activation of the pretensioning device during the funding process can take place.
- a slip occurring during a conveying process can be counteracted, for example by the biasing device exerting a greater force.
- an adaptation taking place on a longer time scale can be carried out in order to counteract, for example, determined or predicted wear effects.
- the force applied to the pressing biasing force has a component which acts in the direction of the contact force.
- the relative position of the load cross member and stationary drive device and / or the relative speed between the drive device and the load cross member can be detected by a sensor.
- a sensor signal generated in this way can be used for the activation of the pretensioning device, in particular for adapting the pretensioning force and thus indirectly the propulsion force transmitted to the load traverse via the friction wheel.
- the biasing device is mounted stationary relative to the pressing device. While the pressing device on the friction wheel o- / / and the mating exerts a contact force in the direction of the load spreader and thus at least a part of the pressing device exerts a force exerted by the mating and / or the friction wheel, for example, a pivoting movement in the direction of the load cross bar, with the biasing device be stored stationary and are supported for example on the drive device.
- the biasing means may comprise an eccentric.
- the eccentric is used to implement a rotational movement in a linear translational movement and, for example, comprise a mounted on a shaft control disc whose fulcrum is outside the axis of the shaft.
- the counter-wheel is pivotally mounted about a Gegenradschwenkachse, wherein the Gegenradschwenkachse is oriented perpendicular to the extension of the load cross-member. The counter-wheel can thus be pivoted about the counter-wheel pivot axis in the direction of the load cross-member and optionally exert a variable force on the load cross-member via the contact pressure device.
- the pressing device is pivotally mounted about a Anpressvoriquessschwenkachse, the Anpressvoriquessschwenkachse and the Gegenradschwenkachse run through a common pivot point and preferably parallel to each other.
- the direction of the force introduced via the contact-pressure device does not change on the counter-wheel.
- the friction wheel has a friction wheel axis and the drive device initiates a force on the load carrier substantially perpendicular to a longitudinal alignment of the load carrier and substantially perpendicular to the friction wheel axis. This arrangement ensures optimum initiation of the propulsion force exerted by the friction wheel on the load spreader.
- At least two drive devices are provided in a monorail system, wherein the distance between the two drive devices corresponds at most to the length of a load traverse.
- at least one drive device at a transfer of the passive vehicle from one drive device to the other drive device, also briefly two drive devices, on the load crossbar.
- Figure 1 shows an embodiment of an overhead conveyor according to the invention in a schematically illustrated side view
- Figure 2 is a sectional view taken along the line AA of Figure 1;
- Figure 3 is a sectional view taken along the line B-B of Figure 2 in an active state
- FIG. 4 shows the sectional view of FIG. 3 in a passive state
- Figure 5 shows the overhead conveyor of Figure 1 at a transfer of a wagon train of a
- FIG. 6 shows the monorail of FIG. 1 during a transfer of a workpiece from one
- FIG. 1 shows an embodiment of a monorail 10.
- the monorail 10 is designed for the promotion of heavy loads such as truck frame components, truck T railers or the like. Such a heavy load is shown symbolically in FIG. 1 and provided with the reference numeral 12.
- the monorail 10 has a support rail 14 which are mounted on a raised steel structure 16 (only partially shown).
- the support rail is divided into three parts. While a first part 14.1 and a second part 14.2 are stationary, i. are immovably mounted, a third part 14.3 mounted perpendicular to the plane on a moving bridge movable.
- the load crossmember 20 is designed to accommodate the heavy load, extends substantially along the conveying direction A and is mounted hanging below the passive drives 18. It is structurally divided into two in the present embodiment. The two parts 20.1, 20.2 are hinged together to allow for climb or curve sections correspondingly smaller radii. Of course, one-piece or multi-part load cross members can be realized without departing from the subject matter of the present invention. Also on the support rail 14, two stationary drive means 24 are mounted. These are used to initiate a driving force on the passive vehicle 22, in particular on the load crossmember 20th
- FIG. 2 shows a sectional view along the line A-A of FIG. 1 and serves to better illustrate the drive device 24.
- the drive device 24 has a friction wheel-counter-wheel arrangement 26, also referred to as a friction wheel drive, and a pressure device 28.
- the friction wheel-counter-wheel assembly 26 includes a friction wheel 30 and a mating gear 32.
- the friction wheel 30 is used to transmit propulsive forces on the load crossmember 20, in particular on a first side 34 of the load crossmember 20.
- the mating gear 32 serves to transmit a transverse force to the load crossmember 20 to generate a sufficiently high frictional force between the load cross member 20 and the friction wheel 30.
- the mating gear 32 contacts one of the first side 34 opposite side 36th
- the friction wheel 30 has a drive roller 38, which is driven via an electric motor 40 - possibly coupled via a transmission - and is rotatably mounted about a rotational axis B.
- the axis of rotation B of the drive roller 38 is fixedly mounted relative to the support rail 14 and is not designed to perform linear translational or rotational movements.
- the counter-wheel 32 has a roller 42, which is not driven and mounted on a rotary bearing 33 rotatably mounted about a rotation axis C.
- the pivot bearing 33 itself is mounted on a swivel arm 44 comprehensive pressing device 45.
- the pivot arm 44 is pivotable about a rotation axis D.
- a receiving point 46 for receiving a contact force is provided, which is transferable via a contact pressure arm 48 on the receiving point 46 and thus on the pivot arm 44.
- the Anpressarm 48 is pivotable about the same axis of rotation D and has at its the pivot point D opposite end to a pressure spring 50 which serves to transmit the contact pressure on the pivot arm 44.
- the pivoting range of the Anpressarms 48 is dimensioned so that the apparent in Figure 3 swivel range counterclockwise is limited so that always a transmission of a contact force on the pivot arm 44 is possible.
- the pressing arm 48 itself can in turn be impressed with a biasing force via a displacement device or pretensioning device 52, which is supported on the mounting rail 14.
- the displacement device 52 has a biasing force on the Anpressarm 48 transmitting eccentric 54.
- biasing force transmitting element as an eccentric 54 is shown as preferred, but not to be construed as limiting. There are also other versions possible.
- the transmission can also take place via a direct linear movement or via a pivoting movement.
- the force could also be applied or introduced via a rotational movement in the pressing arm 48 itself.
- the eccentric 54 is in the present case designed as a control disk 58 mounted on a shaft 56.
- the pivot point of the control disk 58 is located outside the axis of the shaft 56 and thus allows a change in the contact force of the Anpressarms 48, which transmits this to the pivot arm 44, by an additive superposition of the introduced through the control disk 58 on the pivot arm 44 biasing force.
- the amount of biasing force is selected via the position of the control disk 58 and is controlled by an adjusting device 60, which can operate, for example, electrically, hydraulically or pneumatically.
- Figure 3 shows a position in which a maximum biasing force is transmitted by means of the control disk 58 to the Anpressarm 44.
- Figure 4 shows a position in which the control disc has no contact with the Anpressarm 44 and thus no biasing force of the contact force superimposed.
- the displacement device 52 thus makes it possible to control the contact force exerted by the pressing arm 48 on the pivot arm 44 and thus indirectly on the passive roller 42 in its height via an actuator - here the displacement device 52.
- the embodiment shown here is a particularly easy to implement and safe realization of the inventive concept. Even with a failure of the actuator 60 of the friction wheel can be operated without interference.
- the roller 42 and the drive roller 38 can in principle be interchanged, i. the drive roller 38 may be movably suspended and roller rigidly mounted.
- the overhead conveyor 10, the displacement device 52 can be used in various ways.
- the reducing diameter and the thereby reducing contact pressure are compensated by an increase in the preload force by simply determining the abrasion or otherwise wearing the drive roller 38 or the roller 42. This can be done independently of the actual operation continuously adjusting or in stages gradually adaptive.
- control variable input to the friction-wheel drive 26 for example, a drive speed for the carriage train 22 (including the load cross-member 14 and passive drives 18), possibly converted into a rotational speed or number of the drive roller-can be compared with an actual speed of the wagon train 22.
- the actual speed of the wagon train 22 may, for example, be sensors are measured along the path of the wagon train.
- the adjustment of the biasing force can for example be done dynamically during a conveying process.
- FIGS. 5 and 6 show various possible uses of the monorail system 10.
- FIG. 5 illustrates a transfer of a wagon train 22 assembled from a load cross-member 20 and passive drives 18 with an attached workpiece 12 to a stationary drive unit 62 which can be moved perpendicularly to the plane, by means of a stationary drive device 24.1 attached to a stationary steel structure 16 and designed as a friction wheel drive.
- the travel bridge 62 likewise has two Drive devices 24.2, 24.3, by means of which the carriage train 22 can be accepted and moved on the travel bridge.
- FIG. 6 illustrates a transfer of a wagon train from a stationary transfer conveyor 64 to the travel bridge 62.
