03/28/2023Autonomous mobile robots from KNAPP - Warehouse flexibility thanks to strong drive solutions
The Open Shuttles, autonomous mobile robots (AMR), from KNAPP enable automation of internal transport without adjustments to the existing infrastructure. The Dunkermotoren drive solutions and gearboxes Framo Morat installed in the AMRs ensure the safe transport of even bulky and heavy loads. How long are you willing to wait for your ordered goods? According to a Statista publication from December 2021, most B2C customers from a total of twelve European countries included to the statistics expect their goods ordered online within three to five days. In the Netherlands, app. One third of the customers expect their goods to arrive after just one to two days.* But also in B2B commerce, speed, flexibility and transparency are getting increasingly important. To meet these requirements, logistics processes within an organization must be designed to be as efficient as possible. But what is efficient today may already be outdated tomorrow. Workflows must be adapted to the fast pace of demands and requirements - and the associated logistics processes must keep pace. A solution to these challenges is offered by the Austrian company KNAPP. Open Shuttles are autonomous mobile transport robots that take over internal transport tasks without adjustments to the existing infrastructure. Thanks to innovative fleet control software, tasks are efficiently distributed to the entire fleet of AMRs. * https://de.statista.com/statistik/daten/studie/652489/umfrage/annehmbare-lieferdauer-bei-online-bestellungen-in-europa/ - abgerufen am 22.11.2022 Travel drive The AMRs of the Open Shuttle series are the flexible alternative to classic tote conveyor technology and transport totes, cartons and trays up to 800 x 600 mm and a maximum payload of 100 kg. Thanks to automatic lifting and width adjustment, the Open Shuttles can accommodate trays of different heights and widths. They are used to connect different storage areas with each other and also supply decentralized workstations. In addition to plenty of intelligence provided by software and sensor technology, the travel drive is an important heart of the AMR. With its more than 70 years of experience in drive technology, Dunkermotoren, a brand of AMETEK, was able to provide the right solution. The autonomous mobile robot is driven by two brushless DC motors of the BG 75 series. The attached controller ensures smooth acceleration and deceleration of the robot. A brake from the Dunkermotoren modular system, which is also integrated into the overall drive, ensures an immediate stop of the AMR in case of an imminent collision with other vehicles or people, which are reliably detected thanks to the integrated laser scanner. The required power for the drive is provided by the hub gearbox from Framo Morat GmbH & Co. KG from Eisenbach, Germany. Together, the two companies - Dunkermotoren and Framo Morat - have already been able to realize many AGV/ AMR projects. Since 2021, they have been presenting a portfolio on the market specially designed for the strict safety and space requirements of AGV solutions. The complete system of motor and gearbox is maintenance-free over the entire service life. If the tread should unexpectedly become damaged or the requirements for the wheel change due to changed ground conditions, it can be replaced and serviced easily and directly on the vehicle. With an acceleration torque of up to 42 Nm, the hub gearbox ensures the Open Shuttle to move even heavy loads without any problems. The emergency stop torque of 63 Nm ensures an immediate stop in case of an imminent collision. Thanks to the complete drive solution from Dunkermotoren and Framo Morath, the Open Shuttle is alway KNAPP's Open Shuttles can be integrated very easily into existing structures and during ongoing operation. To cover seasonal peaks, additional robots can be easily integrated into the fleet and removed again afterwards. Thanks to robust and maintenance-free drive solutions from Dunkermotoren and Framo Morat, the Open Shuttles are reliable, durable, and meet all requirements for small installation space and common interfaces. Are you also planning to implement a driverless transport application? Our sales team will be happy to advise you!s moving safely and reliably. The special feature of the drive solution is the extremely compact design of the overall drive. The gearbox is integrated into the wheel hub and thus disappears into the drive without increasing its length. Lift and steer drive The autonomous mobile robot (AMR), Open Shuttle Fork is the model of choice when it comes to transporting entire pallets, racks or large special load carriers and has a payload of up to 1,300 kg. The integrated automatic lift enables the load to be picked up directly from the ground and allows the load to be placed at heights of up to 1.2 meters. In the Open Shuttle Fork, drive solutions from Dunkermotoren are used for both, the lifting and steering movements, giving the AMR omnidirectional mobility. Thanks to integrated CANopen electronics, the shuttle's higher-level control system can easily address and control the drives. The lift of the up to 1,300 kg, is managed by the most powerful motor available in the Dunkermotoren product portfolio. A brushless DC motor of the BG 95 series with matching planetary gearbox handles even heavy loads without problems. The attached E 600 brake then holds the load in any desired position. If necessary, the brake is also used for an emergency stop at full lift. As soon as a certain safety level is reached, the engine is immediately switched off and the brake guarantees the stop. To always keep the right course, two additional Dunkermotoren drives are installed in the Open Shuttle Fork as a steering unit. The intelligent BLDC motors of the BG 66 series with planetary gearboxes are particularly compact and, thus, perfectly suited for use in flat vehicles. Again, the integrated electronics provide the required intelligence. Thanks to the CANopen interface, the motor receives commands from the higher-level controller of the AMR and can implement even minimal course adjustments of several millimeters. KNAPP's Open Shuttles can be integrated very easily into existing structures and during ongoing operation. To cover seasonal peaks, additional robots can be easily integrated into the fleet and removed again afterwards. Thanks to robust and maintenance-free drive solutions from Dunkermotoren and Framo Morat, the Open Shuttles are reliable, durable, and meet all requirements for small installation space and common interfaces.

03/27/2023Five to one - automation and digitization thanks to smart connection of robots and motors
Innovative and economical solutions usually emerge when people think outside the box. When it comes to automation, this often means combining individual production steps so that workpieces pass through several production stages automatically. The smart networking of individual systems also enables predictive maintenance, monitoring the condition of production equipment and checking production data. The ability to integrate a driverless transport system for picking up and fully automatically transferring the finished parts to the next production step completes the future-proof overall solution. Dunkermotoren, an AMETEK brand based in Bonndorf in the Black Forest, has been developing and producing drive solutions up to 5 kW output power for over 70 years. The manufacturer's modular product strategy allows its brushless and brush DC motors to be combined with gearboxes, encoders, brakes and electronics to create a complete drive solution. The majority of the 1,300-strong company's drive components are manufactured at its headquarters in Bonndorf. For Dunkermotoren, intelligent manufacturing solutions and consistent automation of processes are essential foundations for the competitiveness and quality of its products on the international market. This can be illustrated by the automation of end shield machining, which was developed and implemented by EGS Automation in 2021. The end shield is the front cover of an electric motor from which the drive shaft protrudes. EGS Automation from Donaueschingen has been supplying Dunkermotoren with robot and automation solutions since 2013. The robot specialist has been developing both standardized machine loading systems and customer-specific special solutions since 1996 and specializes in the automation of manufacturing processes in the metalworking industry. The production process at a glance: Bearing shield machining Before automation, the end shields at Dunkermotoren were processed in five operations. Each of these operations was an individual workstation where the end shield was inserted into a machine and removed again after machining. This was followed by manual transport to the next work step. The entire process was thus "difficult to plan and involved a high level of manpower", says Mustafa Koyun, Manager Segment GP Production Parts at Dunkermotoren. Two end shield sizes are machined, of which there are a total of ten variants. The machining includes the drilling of holes and threads, as well as the machining of the inner and outer fit, where the end shield is screwed into the motor housing. Depending on the variant, another recess - internal or external - must be turned on the zinc die-cast component. In addition to the mounting holes in the end shield and the radial holes for screwing into the housing, a final threaded hole is required at some variants for grounding. The automation in detail At the center of the automated machining is an Index ABC lathe, which is advertised by the manufacturer as a dynamic production lathe. Prior to machining, the blanks are present as bulk material in portable mesh containers, where they are poured into a parts hopper by an operator. Via a conveyor system with pre-separation, they enter the detection area of a 3D camera from Keyence, which transmits the position of the blanks and the gripping position to the first robot in the system. This is a six-axis Yaskawa GP7 with a reach of around 900 mm and a payload of 7 kg. The radial orientation of the workpieces is also detected by the camera. A pure binpicking solution was not implemented, to achieve a maximum process reliability and availability, which is independent of detection difficulties and resulting malfunctions. "A very good decision", comments Koyun. "The system runs reliably and stably, and there are no malfunctions or production interruptions." The performance of Yaskawa robots already convinced Dunkermotoren in earlier production lines, which are still running stably. "Handling and adjusting programs is simple and is no problem even for our operators without robot experience after a short training," Mustafa Koyun admits. The robot picks up the unsorted parts and transfers them to a transfer system, where they pass three tapping devices on workpiece carriers. Depending on the part variant, threads are inserted at one or more stations. The tapping units can each insert threads with different hole patterns and sizes. After these processing steps, the workpiece carriers are returned to the first robot via the transfer system. In the transfer system, they are turned and automatically transferred to the transfer shuttle at the input of the index lathe, which feeds them to the machine. Here, the variant-dependent machining of the total of ten end shield variants is carried out. With retooling, most of the time is spent on the machine. With automation, all that needs to be done is to select a different program and adjust the workpiece carriers of the transfer system and the gripping tools of the robots. "This is done in less than five minutes," says Koyun. After machining is complete, the second robot, also a Yaskawa GP7, removes the finished parts and layers them in wash baskets, where they are transported to the cleaning system and cleaned. A changeover station ensures that the baskets can be removed as and when an operator is available without interrupting the automation process. The system is already prepared install a palletizing system from the standard EGS SUMO Ecoplex2 series here at a later date, from which an AGV will pick up the baskets fully automatically and take them to the cleaning system. The line runs completely autonomously for two to three hours, depending on the variant. The insertion of new blanks and removal of finished parts takes only a few minutes, which has reduced employee involvement to a minimum. Production takes place in two shifts. Due to the low employee commitment, an additional shift to cover short-term production peaks would be possible without any problems. Depending on the variant, the cycle time is between 15 and 35 seconds; the output is thus between 800 and 1,900 parts per shift. Dunkermotoren motors and EGS robots make the production plant IIoT-ready A total of six motors from the drive technology manufacturer itself are installed in the complete plant. Brushless DC motors of the series BG perform their duties reliably on the conveyor belts of the feed system, the transfer system and the lifting units for the transfer of parts. The integration of the smart motors are the basis for the integration of the plant into the company's digital infrastructure. Operating states of individual production components, production data and information on required maintenance were to be available online at all times. A task for the IIoT specialists from nexofox. In addition to the recording and processing of critical machine parameters, it should be possible to record and process information from installed components. Due to the installed Dunkermotors, nexofox was able to digitize the plant itself as well as the installed motors. Digitized bearing shield automation In the first step, two Yaskawa robots and three BG motors were digitized. All components were connected at the field level with an EDGE gateway. The motors were connected via the CAN protocol, while the robots were connected via PROFINET. The installed EGDE gateway connects the bearing shield automation with the cloud of Dunkermotoren and is responsible for the communication with the ERP system. The digital software solutions developed by nexofox were built on the standards of the Open Industry 4.0 Alliance (OI 4) at both the field and cloud levels. The underlying standard is defined and described in the respective Asset Administration Shells (AAS). An AAS is to be understood as a reference model that defines the format and location of data storage so that information can later be used for other assets. The reference implementation provided by OI 4 was adapted and implemented at the field level and within the cloud. First, acquired data is used for monitoring the machine. For a fully comprehensive condition monitoring of the plant, different component parameters are used and aggregated. This then results in, for example, OEE values or the energy consumption of the bearing shield automation. With the consequent implementation of the AAS, nexofox opened up the possibility to retrieve or monitor specific parameters of the installed components. Thus, information on motor parameters such as phase current, speed or tracking error, but also important robot parameters such as cycle time, movement hours or temperature at the manipulator are available. The selection of the displayed and used parameters were discussed with Dunkermotoren in advance of the bearing shield automation and adapted to the application. Within the cloud, all parameters of the plant and the components were visualized. Based on the condition monitoring system, third-party systems were integrated at the cloud level. The integration into the SAP maintenance software solution, for example, ensures the further processing of the data provided by nexofox. The basic idea of simple, standardized integration capability was continued in the cloud. Both SAP, also a member of OI 4, and nexofox implemented the respective implementation work on the basis of AAS, which meant that both systems could be integrated with each other without any significant effort. Added value thanks to digitalization If limit values within the condition monitoring system are exceeded, Dunkermotoren is notified. Notifications are divided into messages that are not critical for production and production- or plant-critical alarms that are transmitted directly to the SAP maintenance software. For example, an alarm can be triggered by an unusually rapid rise in temperature at the manipulator. If, as here, a service call would be necessary, the data provided in the SAP maintenance software is passed on to the appropriate service technician. The app developed by nexofox could also be easily integrated into the circuit thanks to AAS and OI 4 standards. This ensures that the service technician can prepare himself optimally in the event of an assignment. Via QR code, the plant can be identified and the service technician can be provided with the latest data. In addition to live data, all plant- and component-specific documents are also provided within the app. After completion of a service, the technician reports back the deployment via the nexofox app. The information about the completion of the assignment including activity report, as well as all service data such as duration of the assignment are reported back to the SAP maintenance software. In addition, the production planner, for example, is notified that the system is ready for production again. The alarm is acknowledged, but is available in the alarm history. This increases transparency and recurring faults can be identified more efficiently and rectified more quickly. The first EGS plant digitized by nexofox was able to prove on several levels that a standards-based IIoT solution can be realized in less than 5 months. In addition, this application shows that the realization of a digitization solution in the Brown Field with a cooperation of different companies is easily possible thanks to simple integrability. Dunkermotoren has significantly increased its efficiency by automating the bearing shield machining and, thanks to nexofox, can fully concentrate on its core competencies even in the event of a malfunction.

03/24/2023The drive unit as an important component in reliable packaging processes
The global connectivity between suppliers and buyers has led to growing expectations towards fast delivery times. In addition to material availability and construction of the actual product, the packaging process is just as important as all preceding steps. The requirements on the packaging machines in terms of speed, precision, flexibility, and connectivity are more important than ever before. This includes e.g., "stand-alone" dosing, feeding, and sorting equipment as well as forming, filling, and sealing machines, cartoners, etc. up to complete packaging lines. Specified cycle times must be maintained reliably and machine downtimes avoided or planned for in advance. Reliable drive components in the packaging process contribute to high reliability and availability of the systems. With its smart BLDC motor portfolio, Dunkermotoren, a brand of AMETEK, offers energy-efficient drive solutions with high power density, which can be used throughout the entire packaging process. With robust standard motors as well as special water and detergent resistant motors for "hygienic designs", all areas of primary, secondary, and transport packaging are served. Thanks to their exceptionally smooth operation, the motors can be easily integrated into goods transportation systems with integrated checkweighers. The highly dynamic and precisely controllable motors enable a high degree of flexibility in the entire packaging process thanks to short switching intervals and start-stop operations. Changing parameters during ongoing operation, such as changes in portioning quantities, product, and packaging formats or conveyor speed can be implemented effortlessly without retooling time. Thanks to integrated bus interfaces, machine data can easily be read down to the individual motor level.This contributes to the overall assessment of machines and packaging lines in terms of process quality, wear and tear, and efficient maintenance planning, as well as the increasingly important environmental footprint of the entire machine. With help from our support team and the capabilities of nexofox, motors can be configured, programmed, and integrated into an existing ecosystem easily and individually. . In addition, holistic concepts for networking systems from field level to the cloud are realized together with the customer. Dunkermotorenoffers valuable expertise ranging from application consulting, support in selecting appropriate hardware, and the integration of individual components, up to the connectivity of entire systems making the drive technology manufacturer a knowledgeable and reliable partner for the whole packaging process.

03/13/2023Dunkermotoren offers a new wheel drive for industrial AGVs and AMRs
NG 1000 WO hub-drive gearboxes for driving industrial trucks with a particularly small ground clearance and a maximum total weight of up to 4 tons With the NG 1000 WO hub gearbox, Dunkermotoren, a brand of AMETEK, presents a gearbox specifically for driver-less transportation systems such as AGVs and AMRs. The abbreviation WO means "with offset" and describes the characteristic axle offset of the gearbox to the attached motor. The design of the gearbox is perfectly matched to the BG 95 brushless BLDC motor. The combination of motor and gearbox requires an overall height of just 95 mm, thus enabling a particularly short ride height and a minimum width of only 600 mm. Thanks to the axle offset, the drives can be arranged side by side when integrated into the vehicle. This increasing the maximum load and acceleration capability of the vehicle while ensuring a narrow chassis. In times when storage space is more expensive than ever, the NG 1000 WO in combination with the BG 95 motor thus contributes to the implementation of space- and cost-efficient logistics solutions and impresses with its power output. The gearbox can carry up to 1000 kg per wheel and reliably transmits acceleration torques of up to 160 Nm. The power of the BG 95x80 can thus be fully utilized and the gearbox is no longer the limiting component. As an example, a four-ton vehicle with two driven wheels of 200 mm diameter each (differential control) can be accelerated to the speed of 2 m/s in just three seconds. When loaded below the maximum load capacity, even better acceleration and maneuverability can be realized. Flexible like all Dunkermotoren drive solutions, the NG 1000 WO can be adapted to your specific requirements in terms of speed control, wheel diameter, and many other parameters to achieve the best result for your application.
