Abstract

The invention relates to a method for managing production orders for a plurality of manual and/or automated processing stations relating to the wiring of electrical components of a switching and/or control system arranged on a mounting plate. The invention further relates to a wire braking station and an arrangement with a wire braking station.

Description

The invention relates to a method for managing production orders for a plurality of manual and/or automated processing stations relating to the wiring of electrical components of a switching and/or control system arranged on a mounting plate, comprising braking wires before they reach manual processing stations. The invention also relates to a corresponding wire braking station and a corresponding arrangement which has a wire braking station.

When manufacturing switchgear and control systems, the wiring process is one of the most central and time-consuming work processes, and is still often carried out entirely manually. Not only the high complexity of the work process but also the requirement for complete freedom from errors places great demands on the people working in switchgear and control system construction.

Different technical aids with different levels of support are known for optimizing the wiring process. This ranges from hand tools and/or semi-automatic machines for wire assembly to fully automatic systems that completely pre-assemble individual wires, for example cutting them to length, stripping them, applying wire end sleeves and crimping them. The pre-assembled cables produced in this way can then be transported and distributed to various downstream processing stations using an air pressure transport system. An arrangement for transporting a wire from a wire assembly machine to a collection point is known, for example, from the EN 10 2021 103 561 B3 . A method for wiring electrical components of an electrical switchgear arranged on a mounting plate is also known from the publication EN 10 2018 133 337 A1 .

However, no technical solution is known to date as an interface between an air pressure transport system for the targeted transport of pre-assembled wires and a manual wiring workstation. In particular, one challenge is to provide pre-assembled wires as a wire sequence arriving at the manual wiring workstation in a predetermined order in a safe and easy-to-handle manner for personnel working at the manual wiring workstation.

It is therefore the object of the invention to provide a method or a device of the type described above so that wires arriving at a manual wiring workstation can be handled as safely and easily as possible.

This object is achieved by the features of the independent claims. The dependent claims each relate to advantageous embodiments of the invention.

• Beziehen einer Planung zumindest einer Schalt- und/oder Steuerungsanlage, die zumindest Ortsinformation und Orientierungsinformation über eine Mehrzahl elektrischer Komponenten der Schalt- und/oder Steuerungsanlage auf einer Montageplatte und Verdrahtungsinformation über eine Mehrzahl elektrischer Verdrahtungen zwischen jeweils zweien der elektrischen Komponenten aufweist;

Accordingly, the method comprises the steps:

• Obtaining a plan of at least one switching and/or control system, which has at least location information and orientation information about a plurality of electrical components of the switching and/or control system on a mounting plate and wiring information about a plurality of electrical wirings between two of the electrical components;

Creating individual processing orders for each of a plurality of processing stations based on the planning of the at least one switching and/or control system, wherein each processing order comprises an individually predetermined wiring sequence of at least partially pre-assembled wires; sending a wire assembly order to a wire assembly machine for sequentially producing a plurality of individually at least partially pre-assembled wires according to the wiring sequences of the individual processing orders;

Instructing the wire assembly machine to output the at least partially pre-assembled wires to the individual processing stations in the respective wiring sequence;

Dispensing the at least partially pre-assembled wires to the individual processing stations by means of an air pressure transport system;

Braking of the wires before reaching the manual processing stations using a wire braking station.

The planning of the switchgear, i.e. in particular the location information and orientation information about the majority of electrical components of the switchgear as well as the wiring information relating to the wiring of the components, can be provided directly from a 3D ECAD system, for example. Additional information relating to the electrical switchgear, insofar as it can support the wiring, can also be obtained via this system. This information can, for example, include individual assembly of individual wiring cables. Determining an automation The determination of the degree of wiring can include determining the suitability for automation of individual wiring steps in which two electrical components of the electrical switchgear are wired together. When providing a plan for the switchgear, component information from the plan can also be provided, preferably at least one dimension of the mounting plate, a type of at least one of the electrical components or of a further component of the electrical switchgear, at least one connection type of at least one of the electrical components, a connection coordinate of at least one of the electrical components, or a geometry of at least one of the electrical components.

It can be provided that the output of a subsequent pre-assembled wire to each of the individual processing stations takes place after receipt of a processing confirmation for the previous wire from the respective processing station. This allows a controlled supply of the wire intended for the next wiring step to the processing stations. The delivery sequence for the individual processing stations is thus determined by the management control or by the wire assembly machine, while the request for the individual wires or the delivery time can be specified by the processing stations as soon as they confirm that the processing of a previous wire has been completed.

The method may further comprise automated or manual wiring of the electrical components in the respective wiring order and according to the wiring information, the location information and the orientation information.

Furthermore, the output of the at least partially pre-assembled wires to the individual processing stations can include instructing a wire switch arranged between the wire assembly machine and the multiple processing stations to feed the respective wire to a target processing station in accordance with the wiring sequence. The wire switch can be part of the wire assembly machine or can be arranged downstream of the wire assembly machine in the wire feed direction along the transport path. In one embodiment, in the wire feed direction up to the wire switch, in the best case, only a single transport line or two or more transport lines for different wire cross-sectional areas can be provided, while in the feed direction of the wire switch, a number of transport lines corresponding to the number of collection points or processing stations to be supplied can subsequently branch off, with each transport line being fed to one of the plurality of collection points, for example a robot and/or a manual workstation. Considering the cycle rates that can be achieved with the wire assembly machine compared to the cycle rates for automated, semi-automated, or manual wiring, a wire assembly machine can be used to serve approximately ten or more pickup points, so that the wire switch can have a corresponding number of pickup transport lines on its output side.

It may be provided that the method further comprises the steps of: detecting the presence of a wire located in a braking station;

Signaling the presence of a wire located in a braking station to an operator of the processing station assigned to the braking station. The presence of a wire located in a braking station can be detected, for example, by means of a presence sensor, for example an inductive ring sensor. The presence of a wire located in a braking station can be signaled to an operator optically and/or acoustically, for example by emitting a signal tone or by lighting up a lamp arranged at the braking station.

In addition, the method can comprise the controlled output of the at least partially prefabricated wire from the wire braking station by means of a feed device provided in the wire braking station. The feed device can be designed to guide the wire located in the wire braking station out of the wire braking station at a speed that is significantly lower than the speed at which the wire arrives in the wire braking station.

The invention further relates to a wire braking station, in particular for use in a method according to one of the preceding claims, for braking a wire transported by means of an air pressure transport system, wherein the wire braking station has a wire receiving device that can be connected to a transport line of the air pressure transport system and a wire output arranged away from the wire receiving device for the controlled output of the wire, wherein the wire braking station has a braking device arranged between the wire receiving device and the wire output for braking a wire rushing along the transport line. The braking effect The braking device can be generated, for example, inductively or by tapering or temporarily blocking the transport path of the wire. The braking device can have two rollers forming a gap, wherein the gap is arranged in the transport path of the wire and the rollers are pre-tensioned against one another so that a wire entering the wire braking station via the wire intake is braked in the gap.

The wire braking station can also have a feed device which is designed to output a wire from the wire output at an adjustable feed speed. The feed device can be designed to drive the rollers in opposite directions, so that a previously braked wire can be guided through the gap and output from the wire output by means of the feed device, overcoming the pre-tensioning force of the rollers. The rollers can be pre-tensioned by a tension spring arranged between them, in particular connecting their roller axes. The rollers can each be mounted on a lever arm which can be pivoted against one another, whereby the rollers can move relative to one another essentially perpendicular to the transport path of the wire for continuous adjustment of the gap to different wire thicknesses. The rollers can each be arranged so that they can rotate on the freely swinging ends of the lever arms. The opposite ends of the lever arms can be pivotably mounted in the wire braking station.

The feed device can have a stepper motor, by which the rollers are driven synchronously by means of at least one belt guided over a deflection roller mechanism. The deflection roller mechanism can be coupled to a motor shaft of the stepper motor via a first belt. The deflection roller mechanism can have a plurality of deflection rollers, two of which are arranged and mounted coaxially with the lever arm axes. Each of these deflection rollers can be coupled to one of the rollers forming the gap via a separate belt, so that the rollers can be driven synchronously and in opposite directions.

Furthermore, it can be provided that the wire braking station has a presence sensor, in particular a ring sensor, by means of which the presence of a wire located in the wire braking station can be detected. The presence sensor can be arranged in such a way that the tip pointing in the transport direction of a wire located in a braking position in the wire braking station is located in the measuring range of the presence sensor.

The presence of a wire in the wire braking station can be signaled to operating personnel within the access area of the wire braking station via a signaling device in the wire braking station. The signaling device can be designed to emit acoustic and/or optical signals. For example, the signaling device can emit a buzzing sound or a melody. Alternatively, the signaling device can be designed in the form of one or more lamps, for example LEDs on the outside of the wire braking station.

Furthermore, an actuating device, for example a button, can be provided for manually dispensing a wire from the wire output as soon as the presence of a wire has been signaled. The wire braking station can have a circuit board which is coupled to the presence sensor, the stepper motor, the actuating device and the signaling device. If the presence of a wire in the wire braking station is detected by the presence sensor, the sensor can transmit this information to the circuit board, which can then control the signaling device to inform an operator about the presence of the wire. As soon as the operator actuates the actuating device to dispense the wire, the circuit board can control the stepper motor so that the rollers are driven via this and can dispense the wire via the wire output from the wire braking device.

To reduce the risk for operating personnel in the access area of the wire braking station, the wire output can be designed as an outlet angled away from the transport path. This means that even in the unlikely event of a failure of the braking device, a wire entering the wire braking station from the transport line of the air pressure transport system can still be braked and diverted in a direction away from the operating personnel.

The invention further relates to an arrangement for transporting a pre-assembled wire from a wire assembly machine to a processing station, the arrangement comprising a wire assembly machine, a processing station and an air pressure transport system with a transport line for transporting wires from the wire assembly machine to the processing station, the arrangement comprising a wire braking station according to one of claims 7 to 17, the wire output of which opens into the processing station.

The arrangement can have several processing stations designed as manual wiring workstations, each of which has a transport line and a its wire braking station is assigned, wherein the arrangement further comprises a wire switch arranged between the wire assembly machine and the processing stations with a wire inlet and a plurality of wire outlets, wherein the wire switch is connected on the input side via a transport line to the wire assembly machine and on the output side via respective transport lines to the plurality of processing stations, wherein the wire switch is designed to feed a wire to a target processing station for selectively feeding a wire into one of the transport lines connected to the wire outlets.

1 shows a process overview for a method for automated wiring in control and switchgear construction. This particularly concerns the management of production orders for a plurality of manual and/or automated processing stations 400.1, 400.2 relating to the wiring of electrical components 2 of a switchgear and/or control system arranged on a mounting plate 3. Data flows 15 are indicated by dashed lines and material flows 16 by solid lines. In a database 18 located in the engineering area 7 for storing plans for switchgear and/or control systems and for integrated planning for the creation of circuit diagrams and switchgear cabinet layouts in 3D, corresponding circuit diagrams and switchgear cabinet layouts are first designed and stored in the database 18. Then, circuit diagrams and switchgear cabinet layouts to be produced are exported from the database 18 via a control device 19 located in the workshop area 6 for managing production orders. Based on the circuit diagrams and control cabinet layouts obtained, individual processing orders are then created for each of a plurality of processing stations 400.1, 400.2 by means of the control device 19, wherein each processing order comprises an individually specified wiring sequence of at least partially pre-assembled wires. The control device 19 then sends a wire assembly order 5 to a wire assembly machine 300 for the sequential production of a plurality of individually at least partially pre-assembled wires 1 in accordance with the wiring sequences of the individual processing orders. The wire assembly machine 300 is also instructed to output the at least partially pre-assembled wires 1 to the individual processing stations 400 in the respective wiring sequence. The at least partially pre-assembled wires 1 are then output from the wire assembly machine 300 to the individual processing stations 400 by means of an air pressure transport system 200. The output of the wires 1 to the individual processing stations 400 includes instructing a wire switch 500 arranged between the wire assembly machine 300 and the multiple processing stations 400, which selectively feeds the respective wires to a respective target processing station 400 according to the wiring sequence. The output of a wire 1 to each of the individual processing stations 400 takes place after receipt of a processing confirmation 4 relating to the previous wire 1 from the respective processing station 400. Before reaching the manual processing stations 400.1, the wires arriving there are each braked by means of a wire braking station 100. In the wire braking stations 100, the presence of a wire 1 located in a braking station 100 is detected by means of a presence sensor 112 and the presence of a wire 1 located in a braking station 100 is then signaled to an operator of the processing station 400.1 assigned to the braking station 100. As soon as the operator actuates an actuating device of the wire braking station, the controlled output of at least wire 1 from the wire output of the wire braking station 100 takes place by means of a feed device 104 provided in the wire braking station 100. Finally, the automated or manual wiring of the electrical Components 2 in the respective wiring sequence and according to the wiring information, the location information and the orientation information. The manual wiring workstations also receive information from the control device 19 regarding wiring instructions and a wire list 11, which are each output at the wiring workstations 400.1 via a display 17. The wiring robot 400.2 is coupled to the control device 19 via a human-machine interface 10. This receives a digital twin 14 from the control device 19, which is output from the interface 10 as a robot program 9 to the wiring robot 400.2. The wiring robot 400.2 sends process data 13 to the control device 19 via the human-machine interface 10.

The 2 to 7 The wire braking station 100 shown has a sleeve-shaped wire intake 101 for connection to a transport line 201 of the air pressure transport system 200, via which incoming wires 1 can be fed into the wire braking station 100. On the side of the wire braking station 100 opposite the wire intake 101, a wire output 102 is arranged, via which the braked wires can be guided out of the wire braking station 100 in a controlled manner. Between the wire intake 101 and the wire output 102, the wire braking station 100 has in particular a braking device 103 for braking the wires and a feed device 104 for the controlled guidance of the wires 1 out of the wire braking station 100. The braking device 103 has two conveyor rollers 106 forming a gap 105, wherein the gap 105 is arranged in the transport path of the wire 1 and the rollers 106 are pre-tensioned against each other via a tension spring 111, so that a wire 1 entering the wire braking station 100 via the wire intake 101 is braked in the gap 105. The feed device 104 is designed to drive the rollers 106 in opposite directions, so that by means of the feed device 104 a previously braked wire 1 can be guided through the gap 105 and out of the wire output 102, overcoming the pre-tensioning force of the rollers 106. The conveyor rollers 106 are each mounted on a lever arm 107, wherein the lever arms 107 can be pivoted relative to one another, whereby the conveyor rollers 106 can be moved relative to one another essentially perpendicular to the transport path of the wire 1 for the continuous adjustment of the gap 105 to different wire thicknesses. The feed device has a stepper motor 108, by means of which the rollers 106 are driven synchronously by means of a deflection roller mechanism 109 and several belts 110.1, 110.2. The deflection roller mechanism has three deflection rollers which are coupled to a motor shaft 108 of the stepper motor via a first belt 110.1, wherein the deflection rollers are driven in such a way that two deflection rollers each lying in line with one of the conveyor rollers 106 are driven in opposite directions and synchronously. These two deflection rollers are also mounted on the lever arms 107 and can rotate coaxially to the pivot axes of the lever arms 107. These deflection rollers are each coupled to one of the conveyor rollers 106 by a separate belt 110.2, so that they are also driven synchronously and in opposite directions.

A ring sensor 112 is also installed in the wire braking station, by means of which the presence of a wire 1 located in the wire braking station 110 can be detected. The ring sensor 112 has a passage opening through which the wire 1 passes after passing through the gap 105. The presence of a wire 1 located in the wire braking station 100, detected by the ring sensor 112, is then signaled to operating personnel located within the access area of the wire braking station 100 via a signaling device 113 located in the wire braking station 100. An operator can manually trigger the dispensing of a wire 1 from the wire dispenser 102 via a button 114 as soon as the presence of a wire 1 has been signaled. The wire dispenser 102 is designed as an outlet angled downwards from the transport path to reduce the risk for operating personnel located within the access area of the wire braking station 100. The wire braking station 100 also has a circuit board 115 which is coupled to the ring sensor 112, the stepper motor 108, the actuating device 114 and the signaling device 113. When the presence of a wire 1 in the wire braking station 100 is detected by means of the ring sensor 112, the latter transmits this information to the circuit board 115, which then controls the signaling device 113 to inform an operator about the presence of wire 1. As soon as the operator actuates the actuating device 114 to dispense the wire 1, the circuit board 115 can control the stepper motor 108 so that the conveyor rollers 106 are driven via this and the wire 1 is dispensed from the wire braking device 100 via the wire output 102.

This comprises the steps of obtaining 1000 a plan of at least one switching and/or control system, which has at least location information and orientation information about a plurality of electrical components 2 of the switching and/or control system on a mounting plate 3 and wiring information about a plurality of electrical wirings between two of the electrical components 2;
