Description of the prior art

Conveyor systems are known from the prior art, in which the conveyor line is composed of different line sections. So rail systems are known, such as a one-rail floor railways, in which various straight rail pieces, curved rail pieces as well as driving course branches and driving course mergers and portable rails are used.

Curved route sections can be provided for changing the direction of movement of the trolley in the vertical and / or horizontal direction.

Furthermore, the driving course branches offer the trolleys different sections of the route after leaving the junction. Driving course mergers, on the other hand, offer the possibility of driving from different route sections to a common route section of the conveyor route.

Such conveyor systems are used, for example, to transport workpieces in at least part of a larger production system. Such a part of a production plant for workpieces can be, for example, a production area, a surface treatment area, a storage area, an assembly area, a control area and / or a connection area between other parts of the production plant.

The conveyor system can have a purely transport function of the workpieces between two areas. However, it is also possible for the conveyor system to move the workpieces within one area by means of a process step. The carriages are therefore sometimes stopped at certain stations so that a corresponding process step can be carried out on the workpiece.

In order to follow the course of the route and in particular a rail, the trolleys have a running gear with an entrained drive, for example in the form of a friction wheel. Furthermore, such a chassis can have further guide elements, such as guide rollers.

The drive usually comprises an electric geared motor, the energy supply of which is ensured by means of conductor lines along the conveyor line or energy storage devices carried along, such as batteries, compressed gas containers and / or capacitors. Inductive energy concepts are also known.

Such a conveyor system is controlled by a so-called system controller. The complex processes of the entire production plant are broken down into smaller logical units according to the “divide and conquer” principle. This also applies to the design of the conveyor system. Therefore, concepts are known in which the system control only indicates the destinations to which the trolleys are to be driven, and the trolleys themselves carry their own trolley controls which control the movement of the trolleys, in particular their travel speeds.

For example, changes in the speed of travel of the carriages are required when they travel through a curve area of the conveyor line. Compared to a straight conveyor line, there may be higher mechanical loads on the trolley chassis.

It may also be necessary for the trolleys to temporarily stop at certain points in the conveyor system. This may be necessary, for example, in the corresponding processing and / or treatment areas. Switching the route changing devices can also require a short standstill of the trolleys.

Such an action, such as changing the driving speed or stopping the trolley, therefore takes place as a function of the position of the trolley along the conveyor line.

Usually, waypoints are set at such conveyor systems along the route at which certain actions are triggered.

The waypoints can be provided as physical switches which, for example, switch a trolley into a slow driving speed in front of a curve. Typically, however, the waypoints are provided virtually by the system controller. For this purpose, the trolleys can, for example, carry a reading device with which position codes can be read out along the conveyor line. The system control then specifies a certain position along the conveyor line as a waypoint.

The position of the waypoints along the conveyor line is determined when the conveyor system is designed. The position of the waypoints depends to a large extent on the action to be triggered, the travel speeds provided at the waypoint and / or the other structural requirements.

Above all, the position of the waypoints depends on the wagon parameters of the wagons used in the conveyor system. So trolleys of the same length are always used in a conveyor system. When designing the conveyor system and implementing the system control, depending on the trolley used, for example, a waypoint in front of a switch is set at a position that matches the length of the trolley.

The arrangement of the waypoints is thus determined in the design of the conveyor system in accordance with the requirements of the production system and, above all, the technical properties, that is to say the wagon parameters, of the selected wagon type that will be used in the system.

This initially planned arrangement is then usually corrected within very narrow limits in a pre-operation phase in order to achieve a maximum of the plant throughput. Carriages with different carriage parameters can therefore not be used in such conveyor systems or only to a very limited extent.

SUMMARY OF THE INVENTION

The object of the invention is therefore to provide a conveyor system which is more flexible with regard to the use of different carriages.

• d) mindestens ein zweiter Fahrwagen mit einem zweiten Wagenparameter, der von dem ersten Wagenparameter abweicht, vorgesehen ist, und
• e) die Steuerung dazu eingerichtet ist, mindestens einen Wegpunkt entlang der Förderstrecke, an dem eine bestimmte Aktion ausgelöst wird, für den zweiten Fahrwagen an einer anderen Position entlang der Förderstrecke zu setzen als für den ersten Fahrwagen.

This is achieved according to the invention by a conveyor system of the type mentioned at the beginning, in which

• d) at least one second carriage with a second carriage parameter which deviates from the first carriage parameter is provided, and
• e) the controller is set up to set at least one waypoint along the conveyor line at which a specific action is triggered for the second carriage at a different position along the conveyor route than for the first carriage.

The inventor has recognized that it can be useful in some cases to use the waypoints that are located along the conveyor track for triggering different actions depending on the arriving carriages, specifically when carriages with different carriage parameters are being driven on the same conveyor system have to.

This is especially the case when a like in the as yet unpublished DE 10 2018 109 584.8 described towing process is used. In this, broken down carriages are moved by other carriages out of inaccessible sections of the route.

By means of the present invention, the carriage which is created can nevertheless be reliably moved through the conveyor route with a carriage parameter which differs from normal operation. For the other carriages, nothing changes regarding the waypoints.

The position of the waypoint for the second carriage can be permanently provided at a different position than the waypoint for the first carriage.

For example, the two waypoints for the first and second carriages can be located at different positions along the conveyor route, but only act on the first or second carriages, or the two carriages can only react to one of the two waypoints. For example, two different stop waypoints for the two carriages can be provided in front of a route changing device such as a switch or the like.

The waypoints can also only be moved in the control if required. This can only happen, for example, in the case of a second trolley that is actually present in the conveyor line, so that the waypoints for the corresponding actions are quasi only temporarily shifted for the trolley with a different trolley parameter.

The particular action is an action that is the same for both the first carriage and the second carriage. In particular, the specific action is a change in speed, a Stopping at a stop point and / or a route release.

It is preferably provided that the first and second carriage parameters are a carriage length, a mass, a maximum acceleration, a speed and / or a functional length of the carriage.

The wagon parameters in which the first and second crawlers differ are primarily those parameters which influence the driving behavior of the crawlers. In particular, however, the parameters mentioned can be considered as relevant wagon parameters. The maximum acceleration can be understood to mean both the acceleration and the braking.

The functional length is a length which is virtually predetermined by the control and which, in normal operation, specifies a sufficient minimum distance between two carriages, influences the speed when cornering and / or specifies a necessary stop distance from a route changing device. Conveyor systems are typically designed based on the functional length of the trolley.

The functional length is often also given by the maximum length of the workpieces to be conveyed and / or the maximum carriage length. However, surcharges for safety clearances can also be included in the functional length.

It is preferably provided that the second carriage parameter of the second carriage deviates from the first carriage parameter of the first carriage due to a coupling of two carriages.

The coupling of two carriages, for example, increases the functional length, which can then be taken into account in the control system according to the offset waypoints for executing actions.

When two carriages are coupled, a separating device can preferably be used, with which the flow of force between the drive and the conveyor line is interrupted on a carriage. The drive then takes place via the other coupled trolley. This creates a crawler train consisting of two coupled crawlers, whereby only the drive of the rear or front wagon is used, depending on whether it is pushed or pulled.

Provision is preferably made for one of the two coupled carriages to be a carriage which has failed due to a technical defect.

In this way, a broken down vehicle can be towed. Towing can include both pushing and pulling the broken down vehicle.

The trolley control that is carried along often fails on the trolleys. It can therefore be advantageous to use the still functional drive of a broken down vehicle by establishing an energy transmission connection, for example with the aid of rigid and / or movable electrical contacts, on the two vehicles when coupling to it. At least one of the electrical contacts is advantageously spring-loaded. The electrical contact can be made with or without mechanical coupling of the vehicles to one another.

Furthermore, it is advantageous for the electrical coupling if relative movements of the carriages to one another can be at least partially compensated for by the electrical connection without the connection being disconnected. If the electrical connection is established, this is determined by a pilot contact and the components provided for this malfunction can be used. For example, each trolley can be equipped with a switching unit that, in the event of a malfunction, galvanically isolates the drive motor and the electrical brake from the broken down trolley from its power supply components via an external signal and / or an external power supply and instead connects them to the electrical components of the trolley ,

It is preferably provided that one of the two coupled carriages is a tow truck.

In principle, all trolleys can be designed as trolleys, so that a trolley that has been left behind can be towed away by another trolley. However, a separate tow truck, which differs in structure from the other trolleys, can be advantageous. For example, the tow truck can have a shorter car length, so that the functional length of the two coupled carriages differs only slightly from the functional length of a trolley. This can be relevant for implementers or lifting stations, for example. The other trolleys with their workpieces can also remain in the normal process.

The tow truck can also be designed as a mobile unit, which can be used by operating personnel at any point on the conveyor line that is accessible to the operating personnel, in order to get a broken down vehicle out of an inaccessible area. As a result, only a small section of the conveyor line has to be cleared for towing the broken-down vehicle.

It is preferably provided that the control is set up so that the specific action that is carried out at the waypoint also takes into account the deviation of the second car parameter from the first car parameter.

For example, the speed of two coupled carriages in front of a curve section can not only be reduced earlier but also more strongly. In general, the action at the offset waypoint can therefore take into account in particular the reduced maximum acceleration and braking values, the increased function length, the reduced speed and / or the increased mass. For example, a carriage can have a parameter memory for its own carriage parameters, which are changed in the event of a towing situation.

It is preferably provided that the two carriages carry a carriage control with a waypoint memory and a device for recording their own position along the conveying route, and the second carriage stores another waypoint in the waypoint memory for the specific action.

The trolley control can receive individual waypoints from the higher-level control of the conveyor system, to which the trolleys then move. In this case, the controller transmits a different waypoint to the second carriage for the specific action than to the first carriage.

However, different sets of waypoints can also be stored in the waypoint memory, which are then used either by the first carriage or by the second carriage.

Alternatively, the crawler controller can contain at least one offset value that generates the waypoints from the waypoints of the first vehicle from the second vehicle. The offset value can in turn take into account the deviating car parameters.

The trolley control can also be designed less intelligently, in that the data from the reading device are continuously transmitted to the higher-level control of the conveyor system, so that the specific action is triggered by this control at a waypoint. The information about the different waypoints for the first or second crawler is therefore only stored in the higher-level control system. It is preferably provided that the offset waypoint leads to the use of emergency driving parameters on the second crawler.

It is preferably provided that a carriage with different carriage parameters informs the controller and / or the other carriages.

In this way, the control system can block certain sections of the conveying path for this carriage, for example due to an increased functional length or insufficient driving force for two carriages.

• - Bereitstellen mindestens eines zweiten Fahrwagens mit einem zweiten Wagenparameter, der von dem ersten Wagenparameter abweicht;
• - Setzen mindestens eines Wegpunkts entlang der Förderstrecke, an dem eine bestimmte Aktion ausgelöst wird, für den zweiten Fahrwagen an einer anderen Position entlang der Förderstrecke als für den ersten Fahrwagen.

With regard to the method, the object of the invention is achieved with a method for controlling the conveyor system mentioned at the outset, with the following steps:

• - Providing at least one second carriage with a second carriage parameter that differs from the first carriage parameter;
• - Setting at least one waypoint along the conveyor line at which a specific action is triggered for the second carriage at a different position along the conveyor route than for the first carriage.

• - Zum Abschleppen eines aufgrund eines technischen Defektes, insbesondere in einem für Bedienpersonal schwer zugänglichen Abschnitt der Förderstrecke, liegengebliebenen Fahrwagens ankoppeln eines anderen Fahrwagens an den liegengebliebenen Fahrwagen, wodurch der zweite Fahrwagen realisiert wird;
• - Fahren des zweiten Fahrwagens unter Berücksichtigung des versetzten Wegpunkts.

The following steps are preferably also provided:

• - To tow a trolley that has been left behind due to a technical defect, in particular in a section of the conveyor line that is difficult for operating personnel to couple, connect another trolley to the abandoned trolley, thereby realizing the second trolley;
• - Driving the second carriage taking into account the offset waypoint.

In this way, broken down carriages can be towed.

DESCRIPTION OF PREFERRED EMBODIMENTS

In 1 is a whole with the reference symbol 10 designated conveyor system with a conveyor line 12 and several trams 14 at different positions along the conveyor line 12 shown.

The conveyor line 12 comprises different sections of the route, which in the supervision show roughly two nested circuits, between which the trolleys 14 and the workpieces funded by them, here body examples 15 , with the help of several switches 16 can switch back and forth as route change devices.

To explain what the invention is particularly helpful for, shows 1 in the middle a section of the conveyor line 12 , which represents an area that is difficult to access for operating personnel, here, for example, a painting booth 18 should be. Because inside the spray booth 18 become the tram 14 , as will become clear later from the other figures, below a partition and the bodies 15 led above the partition.

Over the two switches 16 before and after the spray booth 18 can the tram 14 , where the funded bodies 15 should not be painted on a bypass route 20 be performed parallel to the paint booth 18 runs.

In the lower part of the 1 is a maintenance section branching off the main line 22 of the conveyor track recognizable in which tram 14 mostly without a funded body 15 serviced and / or parked.

At the top of the 1 is an example of an empty run buffer 24 shown in which tram 14 including the bodies 15 can be buffered.

Further along the conveyor line 12 (in 1 top right) another converter 26 shown with which the tram 14 to another transport level, for example for further assembly of the motor vehicle. Even with the converter 26 it is a section of the conveyor line 12 which is difficult to access for operating personnel.

Finally, the conveyor line includes 12 connections 28 to other conveyor systems of a higher-level overall production system.

To control the conveyor system 10 is a system control 30 provided here, for example via a wireless communication link 32 with the tram 14 can communicate. Alternatively or additionally, especially in the case of a rail-guided conveyor system as shown here 10 Communication conductor lines along the conveyor line 12 for communication with the tram 14 be used.

In addition, the system control 30 over a communication link 34 also with the production systems, here the painting booth 18 or their working components such as the painting robots. The production systems typically have their own individual controls for this purpose, the only higher-level commands from the system control 30 and internally control the appropriate movement, for example of the painting robot.

After all, the system control 30 over a communication link 36 with the conveyor line 12 , ie especially with those along the conveyor line 12 arranged turnouts 16 and / or other actuators and sensors influencing the travel path.

In the 2 and 3 is a section of the conveyor line 12 in the paint booth 18 shown in a sectional view.

There is only one partition from the paint booth 38 shown which a travel space in which the tram 14 move, separates from the cabin, in which the bodies 15 be performed. The divider 38 has a longitudinal gap through which support rods 39 the tram 14 protrude.

First of all, it can be seen that the conveyor line 12 through a running rail 40 is specified along which a tram is located 14 with the funded body 15 emotional. The tram points to this 14 a landing gear 42 on that own drive 44 with which the tram can move along the rail under its own power 42 can move.

To control the drive 44 the tram leads 14 also a trolley control 46 with that with a reader 48 for example on the running rail 42 attached barcodes or other markings to determine the position of the tram 14 along the route 12 to determine. For the details of an exemplary barcode positioning system, see the DE 10 2012 010 677 A1 directed.

Furthermore, the car points 14 a separator 50 with which the frictional connection between the drive motor 44 and the conveyor line 12 can be separated by actuators 52 . 54 at the front and / or rear end of the trolley. Typically, the flow of force on a transmission of the drive is interrupted. For details on the design of the separation device 50 be on the as yet unpublished DE 10 2018 109 584 of the applicant.

As in 3 shown, the separator 50 to be used a broken tram 14 ' with another tram 14 tow.

To do this, we leave 3 the following tram can be seen 14 on the broken tram 14 ' on, causing the separator 50 is operated. The two cars can also be coupled. The drive 44 of the broken-down tram 14 ' is now virtually idle, so that the following tram 14 with the broken-down tram 14 ' forms a coupled team.

A tram often remains 14 ' because an electrical component fails. It can therefore be advantageous if, when coupling, an electrical bypass contact is simultaneously established with which the towing trolley is being towed 14 can carry out a diagnosis, for example, or sensors that are still functioning, such as a front distance sensor, of the damaged trolley 14 ' can use.

The control 30 can a broken tram 14 ' For example, recognize that a distance sensor on the following trolley 14 detects if the safety distance is undershot and this to the controller 30 reports. Also sensors along the conveyor line 12 can report an expected tram 14 has not arrived at a sensor position within a specified time. The control 30 can then give the order on the broken tram 14 aufzufahren.

After successful coupling, the controller sets 30 determined where the tram left 14 ' must be driven and prepares the corresponding route change devices. The controller can also 30 inform the rest of the process control about the failure of the two vans.

By coupling the two trams 14 and 14 ' changes for the movement of the still functioning tram 14 relevant car parameters. For example, a car parameter is its functional length in normal operation BL (cf. 2 ), which is due to the coupling to a functional length in emergency operation NL (cf. 3 ) elevated.

As explained below, the carriage parameters play an important role in the control of the conveyor system 10 ,

The 4 to 6 show a section of the conveyor line 12 in front of a switch 16 ,

To control the conveyor system 10 gives the system control 30 the trolley control 46 Waypoints, when certain actions are taken. These waypoints are virtual waypoints that are used in the system control 30 are defined and at Design of the conveyor system 10 in the design of the conveyor line 12 be determined.

So in the 4 to 6 with a specified service brake distance BBA in front of the switch 16 a braking waypoint 60 as well as somewhat downstream along the conveyor line 12 a stop waypoint 62 arranged at the operating stop distance BSA. All waypoints, including the braking waypoint 60 and the stop waypoint 62 , are the functional length in normal operation BL of the tram 14 customized.

In 5 has the tram 14 the braking waypoint 60 accomplished what from the reader 48 the trolley control 46 is recognized. Based on a previous specification from the system controller 30 reduces the trolley control 46 at this position the speed of the tram 14 ,

In 6 has the tram 14 the stop waypoint at a slower speed 62 reached, which in turn from the reader 48 is recognized. The tram stops in this position 14 and wait until the turnout 16 has the right route.

Because of the fact that the functional length BL when designing the conveyor system 10 and setting the braking waypoint 60 and stop waypoint 62 the tram comes 14 to stand straight so that its front end just doesn't go into the switch 16 protrudes.

In the 7 to 9 is the same section of the conveyor line 12 in front of a switch 16 shown. However, a coupled team drives out of a tram here 14 and a broken tram 14 ' on the switch 16 to.

The controller has for this emergency driving situation 30 the trolley control 46 of the towing trolley 14 hand over other waypoints (cf. 7 ). This is because of the increased function length in emergency operation NL an emergency braking waypoint 66 to an emergency braking distance NBA upstream. An emergency stop waypoint was also created 68 offset upstream.

In this way, the team comes from the two trolleys 14 and 14 ' like from 9 visible despite its longer functional length NL also optimally in front of the switch 16 to stand.

For the tram following the team 14 apply the braking waypoint again 60 and the stop waypoint 62 , so that the waypoints were only temporarily moved.

In the 10 to 12 is the section of the conveyor line again 12 in front of the switch 16 shown.

However, here is a specially designed tow truck 14 " for use. This builds significantly shorter than the tram 14 and is not intended to convey workpieces. In addition, the tow truck 14 " be designed as a mobile deployment device that can be used by operating personnel at any point on the track. Should the tow truck 14 " the necessary weight is missing to transmit sufficient driving force, spring-loaded pressure rollers for the drive 44 be provided.

In 10 the tow truck drives 14 " Coming from the right onto the broken-down tram 14 ' to. In this case, the tram 14 not towed but towed for towing.

When coupled, the team has from a broken-down tram 14 ' and tow truck 14 " an only slightly longer function length in emergency operation NL compared to the function length in normal operation BL.

Like from the 11 and 12 the control can clearly be seen 30 the emergency braking waypoint 66 to an emergency braking distance NBA downstream from the original position since the reader is now 48 in the team is further ahead than on a normal tram 14 , The emergency stop waypoint also became 68 offset downstream.

Because the tow truck 14 " as another deviating wagon parameter, it can also bring about a lower braking acceleration than a tram 14 the emergency braking distance NBA is proportionally further ahead of the emergency stop waypoint 68 ,
