Definitions

  • Transport device in the form of a long-stator linear motor
  • the present invention relates to a method for starting up a transport device in the form of a long-stator linear motor with a large number of drive coils that are arranged on a stator and a large number of transport units that are moved simultaneously along the stator during operation, with a transport unit for transporting a product is used and a predetermined product flow is realized with the transport device by using predetermined rules for the movements of the transport units during the operation of the transport device movement profiles of the movements of the transport units along the stator are created to implement the product flow.
  • a linear motor has a primary part (stator) and a secondary part (rotor), which is arranged so that it can move relative to the primary part.
  • Drive coils are arranged on the primary part and drive magnets on the secondary part, or vice versa.
  • the drive magnets are designed either as permanent magnets, electrical coils or short-circuit windings.
  • the drive coils are electrical coils that are energized to generate an electromagnetic field by applying a coil voltage. Due to the interaction of the (electro)magnetic fields of the drive magnets and the drive coils, forces act on the secondary part that move the secondary part relative to the primary part.
  • the linear motor can be designed, for example, as a synchronous machine or as an asynchronous machine.
  • the drive coils of the linear motor are arranged either along a direction of movement or in a plane of movement.
  • the secondary part can be moved along this one direction of movement or freely in the plane of movement in the two directions of movement.
  • a distinction can also be made between short-stator linear motors and long-stator linear motors, with the secondary part being shorter or smaller than the primary part in the long-stator linear motor and the primary part being shorter or smaller than the secondary part in the short-stator linear motor.
  • the invention relates to long-stator linear motors, which are expressly understood to mean linear long-stator linear motors (moving in one direction of movement) as well as planar long-stator linear motors (moving in one plane of movement, often also called planar motors).
  • long-stator linear motors a number of secondary parts are usually moved simultaneously and independently of one another along the primary part (in a direction of movement or in a plane of movement).
  • Long-stator linear motors are therefore often used in electromagnetic transport systems in which several transport units (secondary parts) are moved simultaneously to carry out transport tasks. Long-stator linear motors are known from the prior art.
  • drive coils are arranged one behind the other in the direction of movement or next to one another in a plane of movement along a support structure.
  • the drive coils arranged on the support structure form the stator of the long-stator linear motor, which stator extends over the movement path.
  • Drive magnets either permanent magnets or electromagnets, are arranged on a rotor and generate a magnetic excitation field.
  • the runner functions as a transport unit for moving an object. If the drive coils are energized in the area of a rotor, an electromagnetic drive magnetic field is generated, which interacts with the excitation field of the drive magnets to generate a drive force on the rotor.
  • a moving drive magnetic field can be generated, with which the runner can be moved in the direction of movement or in the plane of movement of the long-stator linear motor.
  • the advantage is that a large number of runners can be moved independently of one another on the stator at the same time.
  • it is also already known to construct a long-stator linear motor in a modular manner using stator modules. A certain number of drive coils are arranged on a stator module. Individual stator modules are then assembled into a stator of the desired length and/or shape.
  • WO 2015/042409 A1 shows such a modularly constructed linear long-stator linear motor.
  • US Pat. No. 9,202,719 B1 shows a long-stator linear motor in the form of a planar motor with stator modules.
  • Energizing the drive coils by applying coil voltage also generates heat in stator modules, which can increase the temperature of a stator module. It is therefore already known to cool the stator of a linear motor.
  • US Pat. No. 5,783,877 A or US Pat. No. 7,282,821 B2 shows cooling of a stator of a linear motor, with lines being arranged in the stator or in a component in contact with the stator, through which lines a coolant is fed.
  • the coolant thus absorbs heat from the stator and dissipates it.
  • the cooling of the stator of a long-stator linear motor which can extend over a great length, is, on the other hand, complex in terms of construction and also increases costs, particularly in the case of long stator lengths, such as when used as a transport device.
  • a stator of a planar motor also usually has to be cooled, in particular because in a planar motor a transport unit is held in suspension above the stator by electromagnetic forces, which is done by appropriately energizing the drive coils. With the drive coils must not only the driving forces to Moving the transport units are generated, but also the levitation forces.
  • An example for cooling the stator of a planar motor can be found in DE 10 2017 131 324 A1.
  • Power electronics are provided for energizing the drive coils, which converts the required electrical manipulated variables of the drive coils, for example a coil voltage, a coil current or a magnetic flux. Electrical components are installed in the power electronics, which are loaded during operation, for example by electrical currents flowing through them. However, the permissible electrical currents are limited by the components and/or the electrical configuration of the power electronics.
  • forces and moments also act on the transport unit due to the kinematics of the movement (position, speed, acceleration, jerk (time derivation of the acceleration), impact (double time derivation of the acceleration) over time). These forces are also influenced by the loading of the transport unit (mass and position of the object to be transported).
  • driving forces that are used to move the transport unit, for example along the direction of movement and transverse to it or along a path in a plane of movement or normal to it.
  • the drive coils also generate a levitation force which acts on the transport unit and causes a transport unit to levitate magnetically above the plane of movement.
  • forces and moments can also act on the transport unit which must be absorbed by the mechanical guide of the transport unit in order to prevent the transport unit from flying off the transport route during the movement.
  • centrifugal forces act on the transport unit, which try to lift the transport unit off the transport route.
  • the loading can cause tilting moments, for example, which try to lift the transport unit off the transport route.
  • Centrifugal forces can also act in a planar motor in the area of a curved plane of movement.
  • External forces can also act on a transport unit, for example process forces in a processing station for processing a product transported with the transport unit.
  • the transport unit can be guided along the transport route mechanically, for example by interacting mechanical guide parts on the transport unit and the transport route (such as rollers, sliding surfaces, balls, etc.), but can also be magnetic, for example due to the drive magnets on the transport unit, which are magnetic parts of the guide structure interaction.
  • a combination of such guides is also conceivable.
  • the guidance in a linear long-stator linear motor is usually mechanical and magnetic.
  • a guide for a transport unit of a linear long-stator linear motor is shown, for example, in EP 3 457 560 A1.
  • mechanical guidance is usually not provided, or only in sections, but a transport unit is guided on the basis of electromagnetic levitation forces.
  • a guide for a transport unit of a planar long-stator linear motor is shown, for example, in WO 2018/176137 A1.
  • the electrical supply of the drive coils of the long-stator linear motor must also be ensured during operation. Due to the large spatial extent of a long-stator linear motor and due to the large number of installed drive coils, the electrical supply is usually provided by a plurality of electrical feed sources, with each feed source supplying a plurality of drive coils with electrical energy. Transient movements of the transport units (acceleration, deceleration) are particularly critical for the electrical supply because they require higher electrical power than for movements at constant speed. Especially when accelerating a large number of transport units at the same time (e.g. after a stop or emergency stop), high electrical power can be required.
  • the electromagnetic levitation of the transport units also requires a large amount of electrical energy.
  • more electrical energy is also required for the electromagnetic switch position, because with the drive coils, in addition to the forces in the direction of movement, forces must also be generated transversely thereto.
  • the state of wear of the transport units can also influence the required electrical energy. If, for example, the friction between the transport unit and the guide structure increases due to wear, higher forces for the movement and thus more electrical energy for the movement may be required.
  • a thermal design and/or an electrical design and/or a mechanical design of the transport device is therefore checked on the basis of a time profile of the electrical manipulated variables of the drive coils for realizing a product flow and, before commissioning, a transport device configuration with a thermal and/or electrical and/or mechanical configuration changed if the product flow is not feasible due to the thermal design and/or the electrical design and/or the mechanical design.
  • the steps of determining the mechanical, electrical or thermal condition and changing the transport device configuration can be repeated as required until the process flow can be implemented with the current transport device configuration. In this way, the commissioning can be implemented very reliably and cross-dependencies of changes in the configurations of the transport device configuration that are not immediately recognizable can also be recognized and rectified.
  • the time profile of the electrical manipulated variables of the drive coils is advantageously specified by simulating the movements of the transport units to implement the process flow and thereby determining the electrical manipulated variables of the drive coils required to implement the movements. In this case, it is advantageous if this verification step is also repeated. Through the simulation, a wide variety of assumptions and specifications for the product flow can be taken into account, which means that the check can also advantageously be limited to specific, particularly critical cases. Further advantageous configurations and advantages of the invention result from the dependent claims and from the following description of the invention.

  • sections of the transport path can be formed from a conveying device other than a long-stator linear motor.
  • a return route for the transport units Tn can be designed as a simple conveyor belt, because there are no requirements for the return in terms of the accuracy of the movement.

  • the drive forces are used in order to implement a specific movement profile of the movement of the transport unit Tn, for example with specific kinematic variables such as positions, speeds, accelerations, jerks, etc., with the transport unit Tn.
  • a movement profile is a time course of such kinematic variables or, equivalently, a course of such kinematic variables over the position of the transport unit Tn along the stator 2.
  • the movement of a transport unit Tn along the stator 2 is often not deterministic, ie it cannot be said in advance when which transport unit Tn will be at which position of the stator 2 or what speed, acceleration a transport unit Tn will have at a specific point in time or at a specific time has position.

Which product, and thus which transport unit Tn, is routed to which processing station 6 is determined by a higher-level controller based on certain criteria (for example a number of waiting transport units Tn in front of a processing station 6).
