Description

[0001] Method for managing production orders for a plurality of manual and / or automated processing stations, corresponding wire braking station and corresponding arrangement

[0002] 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 comprising a wire braking station.

[0003] In the manufacture of switchgear and controlgear, the wiring process is one of the most central and time-consuming operations, and is still often performed entirely manually. Not only the high complexity of the process but also the requirement for complete error-free operation places great demands on the people working in switchgear and controlgear construction.

[0004] Various technical aids with varying levels of support are known for optimizing the wiring process. These range from hand tools and / or semi-automatic machines for wire assembly to fully automated systems that completely pre-assemble individual wires, for example, cutting them to length, stripping them, applying wire end ferrules, 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 receiving point is known, for example, from DE 102021103561 B3. A method for wiring electrical components of an electrical switchgear arranged on a mounting plate is also known from the publication DE 10 2018 133337 Ai.

[0005] However, no technical solution has yet been developed for the interface between an air-pressure transport system for the targeted transport of pre-terminated wires and a manual wiring workstation. In particular, one challenge is to provide pre-terminated wires in a predetermined sequence, ensuring that they are safe and easy to handle for personnel working at the manual wiring workstation.

[0006] It is therefore the object of the invention to provide a method and 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.

[0007] This object is achieved by the features of the independent claims. The dependent claims each relate to advantageous embodiments of the invention.

[0008] Accordingly, the method comprises the steps:

[0009] 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 each two of the electrical components;

[0010] 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 specified wiring sequence of at least partially pre-assembled wires;

[0011] 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;

[0012] Instructing the wire assembly machine to output the at least partially pre-assembled wires to the individual processing stations in the respective wiring sequence;

[0013] Dispensing the at least partially pre-assembled wires to the individual processing stations by means of an air pressure transport system;

[0014] Braking of the wires before reaching the manual processing stations using a wire braking station.

[0015] The planning of the switchgear, i.e., in particular, the location and orientation information about the majority of the electrical components of the switchgear, as well as the wiring information relating to the wiring of the components, can be provided directly from a D-ECAD system, for example. Supplementary 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 the individual assembly of individual wiring cables. Determining the degree of automation of the 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 of the switchgear assembly, 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 assembly, 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.

[0016] It can be provided that the output of a subsequent pre-terminated wire to each of the individual processing stations takes place after receipt of a processing confirmation from the respective processing station concerning the previous wire. This allows for a controlled supply of the wire intended for the next wiring step to the processing stations. Thus, the supply sequence for the individual processing stations is determined by the management control system or by the wire processing machine, while the request for the individual wires or the delivery time can be specified by the processing stations as soon as they confirm the completion of processing of a previous wire.

[0017] The method may further comprise automated or manual wiring of the electrical components in the respective wiring sequence and according to the wiring information, the location information and the orientation information.

[0018] Furthermore, the output of the at least partially pre-terminated wires to the individual processing stations can comprise instructing a wire switch arranged between the wire processing machine and the plurality of processing stations to feed the respective wire to a target processing station in accordance with the wiring sequence. The wire switch can be a component of the wire processing machine or can be arranged downstream of the wire processing 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 downstream of the wire switch in the feed direction there is one corresponding to the number of take-off points orA corresponding number of transport lines can be routed from the processing stations, with each transport line being routed to one of the numerous take-off points, for example, a robot and / or a manual workstation. Considering the cycle rates achievable with the wire processing machine compared to the cycle rates for automated, semi-automated, or manual wiring, a wire processing machine can be used to serve approximately ten or more take-off points, so that the wire switch can have a corresponding number of take-off transport lines on its output side.

[0019] It can 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 detection of the presence of a wire located in a braking station can be carried out, for example, by means of a presence sensor, for example an inductive ring sensor. The signaling of the presence of a wire located in a braking station to an operator can be carried out optically and / or acoustically, for example by emitting a signal tone or by illuminating a lamp arranged at the braking station.

[0020] Furthermore, the method can comprise the controlled discharge of the at least partially pre-assembled 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 at the wire braking station.

[0021] 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 intake connectable to a transport line of the air pressure transport system and a wire output arranged remote from the wire intake for the controlled output of the wire, wherein the wire braking station has a braking device arranged between the wire intake and the wire output for braking a wire advancing via the transport line. The braking effect of 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 pretensioned against each other so that a wire entering the wire braking station via the wire intake is braked in the gap.

[0022] The wire braking station can further comprise a feed device configured to dispense a wire from the wire dispenser 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 dispensed from the wire dispenser by means of the feed device, overcoming the pretensioning force of the rollers. The rollers can be pretensioned 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 relative to one another, whereby the rollers can move relative to one another essentially perpendicular to the transport path of the wire for continuously adjusting the gap to different wire thicknesses. The rollers can each be rotatably mounted 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.

[0023] The feed device can have a stepper motor, which drives the rollers synchronously by means of at least one belt guided over a pulley mechanism. The pulley mechanism can be coupled to a motor shaft of the stepper motor via a first belt. The pulley mechanism can have a plurality of pulleys, two of which are arranged and mounted coaxially with the lever arm axes. Each of these pulleys 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.

[0024] Furthermore, the wire braking station can be provided with 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 such that the tip of a wire in a braking position in the wire braking station, pointing in the transport direction, is located within the measuring range of the presence sensor.

[0025] 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 provided 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 tone 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 outlet 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 sensor detects the presence of a wire in the wire braking station, it can transmit this information to the circuit board, which can then control the signaling device to inform an operator of the presence of the wire. As soon as the operator activates the actuating device to dispense the wire, the circuit board can control the stepper motor, which drives the rollers and allows the wire to be dispensed from the wire braking device via the wire outlet.

[0026] To reduce the hazards for operators within the wire braking station's access area, the wire output can be designed as an outlet angled at an angle to the transport path. This allows a wire entering the wire braking station from the air pressure transport system's transport line to be braked and deflected in a direction away from the operator, even in the unlikely event of a braking device failure.

[0027] 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.

[0028] The arrangement can have a plurality of processing stations designed as a manual wiring workstation, each of which is assigned a transport line and a wire braking station connected to the end thereof, wherein the arrangement further comprises a wire switch arranged between the automatic wire processing machine and the processing stations, said wire switch having a wire inlet and a plurality of wire outlets, said wire switch being connected on the input side via a transport line to the automatic wire processing machine and on the output side via respective transport lines to the plurality of processing stations, said wire switch being 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.

[0042] Fig. 1 shows a process overview for a method for automated wiring in control and switchgear construction. This relates in particular to 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 as well as 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 control cabinet layouts to be manufactured are exported from the database 18 via a control device 19 located in the workshop area 6 for managing production orders. Based on the obtained circuit diagrams and control cabinet layouts, individual processing orders are then created for each of a plurality of processing stations 400.1, 400.2 by the control device 19, with each processing order comprising 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 according to the wiring sequences of the individual processing orders.Furthermore, the automatic wire processing machine 300 is instructed to dispense the at least partially pre-terminated wires 1 to the individual processing stations 400 in the respective wiring sequence. The at least partially pre-terminated wires 1 are then dispensed from the automatic wire processing machine 300 to the individual processing stations 400 by means of an air pressure transport system 200. Dispensing the wires 1 to the individual processing stations 400 comprises instructing a wire diverter 500 arranged between the automatic wire processing machine 300 and the plurality of processing stations 400, which selectively feeds the respective wires to a respective target processing station 400 according to the wiring sequence. Dispensing a wire 1 to each of the individual processing stations 400 occurs 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 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 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 dispensing of at least one wire i 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. At the manual wiring workstations 400.1 and at the wiring robot 400.Finally, the automated or manual wiring of the electrical components 2 takes place 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 concerning 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. The wiring robot 400.2 receives a digital twin 14 from the control device 19, which is output by 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.

[0043] The wire braking station 100 shown in Figures 2 to 7 has a sleeve-shaped wire intake 101 for connection to a transport line 201 of the pneumatic transport system 200, through 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, through 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 removal of the wires 1 from 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 pretensioned 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 pretensioning force of the rollers 106. The conveyor rollers 106 are each mounted on a lever arm 107, wherein the lever arms 107 are pivotable relative to one another, whereby the conveyor rollers 106 are movable relative to one another essentially perpendicular to the transport path of the wire 1 for continuously adjusting the gap 105 to different wire thicknesses.The feed device has a stepper motor 108, by 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 108.1 of the stepper motor 108 via a first belt 110.1. The deflection rollers are driven in such a way that two deflection rollers, each aligned 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.

[0044] Furthermore, a ring sensor 112 is installed in the wire braking station 100, by means of which the presence of a wire 1 located in the wire braking station 100 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 within the access area of ​​the wire braking station 100 via a signaling device 113 provided in the wire braking station 100. Using a button 114, an operator can manually trigger the dispensing of a wire 1 from the wire dispenser 102 as soon as the presence of a wire 1 has been signaled. To reduce the danger for operating personnel within the access area of ​​the wire braking station 100, the wire dispenser 102 is designed as an outlet angled downwards from the transport path.The wire braking station 100 further comprises 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. Upon detecting the presence of a wire 1 in the wire braking station 100 by means of the ring sensor 112, the sensor transmits this information to the circuit board 115, which then controls the signaling device 113 to inform an operator of the presence of the 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 the stepper motor, and the wire 1 is dispensed from the wire braking device 100 via the wire dispensing device 102. Fig. 8 schematically shows a flow diagram of an embodiment of a method according to the invention.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 each two of the electrical components 2;.
