- the present invention further relates to a method for setting up a safety system for a machine.
- the present invention further relates to a computer program product.
- the basis of automatic or assisted risk assessment is virtual models of the machine as well as virtual models of the safety technology used.
- the models can be used to simulate changes and to test and check the safety precautions before the system is actually changed.
- the automatic or assisted risk assessment hereinafter referred to as automated risk assessment, can provide the safety engineer with appropriate recommendations and assist in minimizing risks in accordance with standards.
- a regular risk assessment can be carried out in a structured, quick and at least partially automated manner, especially if the automatic risk assessment can rely on real runtime data. Such a concept is shown as an example in EP 3 702 855 A1.
- a hazard analysis of machines must be carried out in accordance with the EN ISO 12100 standard.
- the EN ISO 12100 standard defines the basic terminology and methodology and provides general principles for risk assessment and risk reduction to help designers produce safe machines.
- An important aspect of analysis is the evaluation of danger points or danger spots on a machine that pose a potential danger to people.
- Danger points can be, for example, mechanical, thermal or electrical danger points.
- Mechanical danger points are, for example, areas of the machine that can pose a danger to people due to their surface contour, such as edges or points.
- Electrical hazards For example, areas or parts of the machine that are live or under voltage when the machine is in operation.
- Thermal hazard points are, for example, areas or parts of the machine in which heat can develop during operation of the machine. It is understood that the person skilled in the art may be aware of other types of hazards than those mentioned here.
- danger points of a machine are determined, their accessibility for humans is checked and, if necessary, secured using suitable protective measures.
- CE certification has been carried out manually by an examiner.
- the test specimen was previously analyzed manually by an inspector at his own discretion for danger points, the accessibility of the danger points was determined, and, if necessary, appropriate protective measures were determined.
- a safety system can be provided with which certain danger points on the machine can be secured.
- the security system can, for example, have sensors, cameras, edge protection or barriers by means of which the danger points can be secured.
- the standard EN ISO 13857 specifies safety distances against reaching hazardous areas with the human body, in particular with the upper and lower limbs. To determine whether the danger zones of a machine can be reached, an inspector has previously checked manually whether the machine complies with the safety distances against reaching danger zones in accordance with the EN ISO 13857 standard and whether further protective measures need to be taken if necessary.
- this object is achieved by a computer-implemented method for determining a security configuration of a security system for a machine, the machine having a danger point, with the following steps:

Furthermore, can also a computer program product may be provided which comprises instructions which, when the program is executed by a computer, cause it to carry out the steps of the method according to the first aspect of the invention.
- the new method is implemented using a processing unit or a control device, which may be a general-purpose computer or a special-purpose computer, wherein an appropriate computer program or computer program product is stored and executed, the computer program or the computer program product being used to determine the security configuration of the security system for the machine or for setting up the safety system for the machine is designed and trained in accordance with the aforementioned methods.
- a processing unit or a control device which may be a general-purpose computer or a special-purpose computer, wherein an appropriate computer program or computer program product is stored and executed, the computer program or the computer program product being used to determine the security configuration of the security system for the machine or for setting up the safety system for the machine is designed and trained in accordance with the aforementioned methods.
- the new methods serve to protect a machine that has at least one point of danger.
- At least one danger point means that the machine can have one danger point or a plurality of danger points.
- the danger points can be, for example, mechanical, electrical or thermal danger points.
- the at least one danger point of the machine is predetermined or known in advance. For example, the exact location or area of the danger point can be determined in advance by a human, in particular by an inspector, or by means of a computer-implemented method or program by analyzing the machine or a virtual model of the machine.
- the accessibility of the machine will first be determined for a danger point, in particular for each danger point.
- accessibility it is determined in particular whether and how the danger point is accessible or reachable.
- appropriate protective measures can then be taken to secure the respective danger point.
- a security configuration of a security system for the machine is defined for appropriate protection.

- the plurality of geometric shapes may comprise two or more groups.
- the geometric shapes in a group have the same size, especially the same shape.
- the groups differ from one another in the shape and size of the geometric shapes. In other words, each group has a number of geometric shapes of a different size, particularly shape.
- the plurality of geometric shapes may include one or more geometric shapes of a first size (corresponding to a first group), one or more geometric shapes of a second size (corresponding to a second group), and one or more geometric shapes of a third size (corresponding to a third group ) exhibit.
- each geometric shape of the plurality of geometric shapes can also have a different size.
- the geometric shapes can be, for example, spheres, cylinders or tubes.
- the size of the geometric shape preferably corresponds to the volume of the geometric shape or the extent of the geometric shape in a specific spatial direction. In the case of a sphere, the size is defined in particular by the radius or diameter. For a cylinder, the size can be defined, for example, by the length and/or the radius.
- the size of the geometric shapes can be adapted in particular to dimensions of body parts of the human body (for example body, arm, hand, finger and fingertip).
- the plurality of geometric shapes is preferably a plurality of spheres of different sizes (i.e. different diameters).
- the diameter of a ball can be 100 cm to 200 cm (roughly corresponding to an average body size), and such a ball can be referred to as a body sphere.
- the diameter of a ball can also be 4 cm to 12 cm, preferably 5 cm to 10 cm, in particular 7 cm (roughly corresponding to an average arm thickness), and such a ball can be referred to as an arm ball.
- the majority of geometric shapes can have multiple arm balls.
- the plurality of geometric shapes may have three, four, five or more arm balls.
- the number of arm balls can in particular be chosen so that the product of the number and the diameter of the arm balls is 40 cm to 100 cm, preferably 50 cm to 80 cm, in particular 60 cm or 70 cm (approximately corresponding to an average arm length) .
- the diameter of a ball can also be 5 cm to 15 cm, in particular 10 cm (roughly corresponding to an average hand thickness), such a ball being referred to as a hand ball.
- the majority of geometric shapes can have multiple handballs.
- the plurality of geometric shapes may include three, four, five or more handballs.
- the number of hand balls can in particular be chosen so that the product of the number and the diameter of the hand balls is 5 cm to 20 cm, preferably 7 to 15 cm (roughly corresponding to an average hand length).
- the diameter of a ball can also be 0.5 cm to cm, preferably 1 cm to 2 cm, in particular 1.5 cm (approximately corresponding to the thickness of a finger), such a ball being referred to as a finger ball.
- the majority of geometric shapes can have multiple finger balls.
- the plurality of geometric shapes can include three, four, five or more finger balls.
- the number of finger balls can in particular be chosen so that the product of the number and the diameter of the finger balls is 5 cm to 15 cm, preferably 7 cm to 10 cm, in particular 8 cm (roughly corresponding to an average finger length).
- the plurality of geometric shapes has a body ball, one or more arm balls and one or more finger balls.
- the plurality of geometric shapes can also have one or more hand balls.
- the plurality of geometric shapes may include a body sphere, one or more arm spheres and one or more hand spheres.
- an arrangement of one or more of the geometric shapes around the danger point is simulated.
- the arrangement of one geometric shape or a combination of geometric shapes can be considered.
- one or more of the geometric shapes can be simulated where they can be arranged around the danger point.
- “Arrangable” means that a geometric shape is freely arranged in space and does not lie in or overlap with a component of the machine.
- the hazard point can be reached with a geometric shape if a geometric shape or a combination of geometric shapes can be arranged so that it is adjacent to the hazard point.
- the simulation can be limited to a specific area around the danger point.
- the respective geometric shape can be generated at different positions in the virtual environment, in particular in the specific area around the danger point. For each position it can then be determined whether the geometric shape can be arranged at this position. Alternatively, the geometric shape can only be at one position in the virtual environment, in particular in the specific area around the danger point and then moved accordingly in the virtual environment.
- the accessibility of the danger point is next determined. In particular, it is determined whether and how the danger point can be accessed. For example, if the danger point cannot be reached with any of the geometric shapes or with any particular combination of geometric shapes, the danger point is not accessible. If the danger point can be reached with a geometric shape or with a certain combination of geometric shapes, the danger point is accessible with this geometric shape or with this certain combination of geometric shapes.
- the safety system can have various protective devices to protect danger points on the machine.
- physical protective devices such as edge protection, barriers, markings and the like or sensory ones such as sensors, light grids, cameras and the like can be provided as protective devices.
- a physical protective device can be used to protect a hazardous location by making access to it more difficult or prevented by appropriately arranging the physical protective device.
- a danger point can be secured by monitoring an area, i.e. a safety zone, around the danger point using the sensory protection device.
- the area can be defined, for example, by a safety distance from the danger point.
- the sensory protective devices can be connected to a control device of the security system. If it is detected that a person is entering or staying in the monitored area, appropriate protective measures can be taken.
- the protective device or the control device of the security system can be set up to output a visual or acoustic alarm signal or to switch off the machine if it is detected that a person is entering or staying in the monitored area.
- a security configuration of the security system thus defines the arrangement and/or configuration of one or more protective devices of the security system.
- the security configuration can be defined by one or more parameters.
- a parameter of the safety configuration thus determines the arrangement and/or configuration of one or more protective devices. In other words, a parameter of the security configuration determines a protective measure to secure the point of danger.
- the safety configuration is determined in such a way that no arrangement and/or configuration of one or more protective devices of the safety system is set up to protect the danger point.
- the required protective measure depends on how, in particular with which geometric shape or which combination of geometric shapes, the danger point is accessible.
- the safety configuration can in particular be determined in such a way that the arrangement and/or the configuration of one or more protective devices of the safety system for securing the danger point are set up in accordance with the specific accessibility. For example, fine-mesh finger protection can be placed directly around the danger point or coarse-mesh access protection a little further away.
- the safety system can then be set up accordingly in order to secure the danger points of the machine when it is accessible.
- a protective measure is implemented to prevent or make it more difficult for people to get injured at the danger points.
- the The machine is commissioned and operated with the safety system set up in this way.
- the machine can be set up to process and/or package and/or transport objects after commissioning.
- the machine may include a machine tool and/or a robot and/or a conveyor mechanism, such as a conveyor belt, each of which poses a danger to people during operation.
- the new, proposed method thus provides a method for the automated determination of accessibility to a danger point.
- the new process can be used to automatically determine whether and how a danger point is accessible.
- CE certification can be carried out automatically.
- the proposed method offers the advantage that the determination can be carried out quickly, reliably and, in particular, at an early stage in the development process (for example based on a CAD design model).
- appropriate protective or security measures are determined based on the specific accessibility of the danger points.
- a security configuration of the security system is determined based on the specific accessibility to the danger point.
- the security system can then be set up according to the specific security configuration to secure the machine. In this way, the safety of the machine is improved.
- the new, proposed method improves the detection and protection of danger points on a machine.
- a corresponding area is successively created in the virtual Environment determined in which the respective geometric shape can be arranged around the danger point.
- “Sequentially” means that first an area is determined for a first geometric shape, then a further area for a further geometric shape, etc.
- the areas can be in descending or ascending order according to the size of the geometric shapes be determined.
- the area of the respective geometric shape is an area in the virtual environment, which in particular includes all possible arrangements of the geometric shapes around the danger point.
- the determination of where the respective geometric shape can be arranged in the virtual environment around the danger point can be limited to a specific area of the virtual environment, preferably in the immediate vicinity of the danger point (for example within 3 m around the danger point).
- possible (especially all possible) arrangements (position/orientation) of the geometric shape in the virtual environment (outside the virtual model) and preferably within the restricted area are determined for the respective geometric shape, whereby the possible (especially all possible) arrangements then cover or define the corresponding area of the geometric shape.
- the area for the respective geometric shape can be done, for example, by scanning (the variation of the position and/or orientation of the geometric shape or motion simulation) of the virtual environment (or a restricted area of the virtual environment) using the respective geometric shape, it being determined where the geometric shape can be arranged in the virtual environment or in the restricted area of the virtual environment.
- the area to be determined is then the area that is covered by all specific possible arrangements.
- a subsequent area is determined such that in this area the respective geometric shape can be arranged around the danger point, starting from the previously determined areas.
- “Starting from” is to be understood as meaning that a subsequent geometric shape overlaps with or borders on at least one of the previous specific areas.
- the corresponding area is first determined for a first geometric shape, where the geometric shape can be arranged in the virtual environment or in the restricted area of the virtual environment around the danger point. It is then determined for each subsequent geometric shape where this geometric shape can be anodeed in the virtual environment or in the restricted area of the virtual environment starting from at least one of the previously determined areas, these arrangements of the subsequent geometric shape then defining the corresponding area . In this way, the arrangement of a combination of geometric shapes can be simulated.
- a first area is determined in the virtual environment around the danger point, in which a first geometric shape, preferably within a defined area, can be arranged around the danger point.
- the first area is determined for the first geometric shape of the plurality of geometric shapes. This determines where the first geometric shape can be arranged in the virtual environment within the defined area. The first area is then the area that is covered by all specific possible arrangements of the first geometric shape.
- the defined area is preferably a subarea of the virtual environment. The danger point is preferably in the defined area (in particular in the middle of the defined area).
- the first geometric shape can be a body sphere.
- the defined area can, for example, be an envelope such as a surface, in particular a sphere, which surrounds the virtual model.
- the first area can also be determined as the area in which the first geometric shape can be arranged adjacent to the virtual model of the machine.
- a second area is determined in the virtual environment around the danger point, in which a second geometric shape can be arranged around the danger point, starting from the first area.
- the plurality of geometric shapes has the second geometric shape.
- the second geometric shape is then the area that is covered by all specific possible arrangements of the second geometric shape.
- the second geometric shape is smaller than the first geometric shape.
- the first geometric shape can be a body ball and the second geometric shape can be an arm ball.
- a third region is determined in the virtual environment around the danger point, in which a third geometric shape can be arranged around the danger point, starting from the first and/or the second region.
- the plurality of geometric shapes has the third geometric shape.
- the third geometric shape can be arranged in the virtual environment starting from the first area and/or the second area.
- the third area is then the area that is covered by all specific possible arrangements of the third geometric shape.
- the third geometric shape is smaller than the first geometric shape and the second geometric shape.
- the first geometric shape can be a body ball
- the second geometric shape can be an arm ball
- the third geometric shape can be a finger ball.
- further areas can be determined based on at least one of the previously determined areas.
- the areas are determined one after the other in descending order of the size of the geometric shapes.
- the first geometric shape by means of which the first area is determined is then the largest geometric shape of the plurality of geometric shapes.
- Each additional area is then determined using the next smaller geometric shape. In this way, it can be determined in particular whether the point of danger is: outside to inside can be achieved via a combination of geometric shapes arranged in descending order.
- a subsequent area is only determined if none of the previously determined areas adjoins the danger point.
- the danger point is reached with a specific geometric shape, in particular if the corresponding area is adjacent to the danger point, it is no longer necessary that the subsequent (smaller) geometric shapes have to be considered. It is therefore advantageous to determine the area of a subsequent geometric shape only if the areas of the previous (larger) geometric shapes do not border the danger point.
- the second area is only determined if the first area does not border the danger point.
- the third area is only determined if the first area and the second area do not border the danger point.
- the step of determining the accessibility of the danger point it is determined that the danger point is accessible if one of the specific areas adjoins the danger point.
- the danger point As soon as one of the specific areas adjoins the danger point, this means that the danger point has been reached with the corresponding geometric shape of the area. The danger point is then accessible. If none of the specified areas are adjacent to the hazard point, the hazard point cannot be reached with any of the geometric shapes. The danger point is therefore not accessible.
- the step of determining accessibility it can be determined in particular with which geometric shape or with which combination of geometric shapes the danger point is accessible. If one of the specified areas is adjacent to the danger point, the danger point is accessible with the corresponding geometric shape (in particular with a combination of the geometric shapes from the first (largest) to the geometric shape whose area is adjacent to the danger point).
- a first area is determined in the virtual environment around the danger point, in which a first geometric shape can be arranged adjacent to the danger point.
- the plurality of geometric shapes has a first geometric shape.
- one of the plurality of geometric shapes that can be arranged adjacent to the danger point can be determined as the first geometric shape.
- a first area is then determined around the danger point, in which the first geometric shape can be arranged adjacent to the danger point. Starting from this first area, further areas with larger geometric shapes can then be determined. In this way, it can be determined, particularly from the inside out, whether the danger point can be reached with a combination of geometric shapes.
- the first geometric shape can be a finger ball.
- a second area is determined in the virtual environment around the danger point, in which the second geometric shape can be arranged starting from the first area around the danger point.
- the plurality of geometric shapes has the second geometric shape.
- the second geometric shape can be arranged in the virtual environment starting from the first area.
- the second area is then the area that is covered by all specific possible arrangements of the second geometric shape.
- the second geometric shape is larger than the first geometric shape.
- the first geometric shape can be a finger ball and the second geometric shape can be an arm ball.
- a third region is determined in the virtual environment around the danger point, in which a third geometric shape can be arranged around the danger point, starting from the first and/or second region.
- the plurality of geometric shapes has the third geometric shape.
- the third geometric shape can be arranged in the virtual environment starting from the first area and/or the second area.
- the third area is then the area that is covered by all specific possible arrangements of the third geometric shape.
- the third geometric shape is larger than the first geometric shape and the second geometric shape.
- the first geometric shape can be a finger ball
- the second geometric shape can be an arm ball
- the third geometric shape can be a body ball.
- the areas are determined one after the other in increasing order of the size of the geometric shapes.
- the first geometric shape by means of which the first area is determined is then not the largest geometric shape of the plurality of geometric shapes.
- Each additional area is then determined using the next larger geometric shape. In this way, it can be determined in particular whether the danger point can be reached from the inside to the outside via a combination of geometric shapes that are arranged in ascending order.
- a subsequent area is only determined if every previous area can be determined.
- An area can only be determined if the corresponding geometric shape can also be arranged.
- the first area can be determined if the first geometric shape can be arranged adjacent to the danger point.
- Each further area, in particular the second and third areas, can be determined if the corresponding geometric shape can be arranged starting from at least one of the already determined areas.
- the second area is only determined if the first area was determinable.
- the third area is only determined if the first and second areas could also be determined. If all areas starting with the first area up to the area of the largest geometric shape can be determined, the danger point can be reached with this combination of geometric shapes.
- a new first geometric shape can be determined (the next smaller one to the previous first geometric shape). Then, starting from the new first geometric shape, the areas can be determined one after the other in ascending order of the size of the geometric shapes. If there is no longer a smaller form, it means that the danger point is not accessible.
- the danger point it can be determined whether one of the plurality of geometric shapes can be arranged adjacent to the danger point and, if so, which is the largest geometric shape that can be arranged at the danger point. If none of the geometric shapes can be arranged adjacent to the hazard point, the hazard point cannot be reached with any of the geometric shapes. In particular, in this case it is not possible to determine an area that is adjacent to the point of danger (i.e. the first area cannot be determined). In this case, the danger point is not accessible. However, if one of the geometric shapes can be arranged adjacent to the danger point, this geometric shape is determined as the first geometric shape. In particular, the first one that can be arranged adjacently is determined as the first geometric shape.
- the danger point in the step of determining the accessibility of the danger point, it is determined that the danger point is accessible if all areas to be determined can be determined. In particular, starting from a first geometric shape, an area is to be determined one after the other for each of these shapes in ascending order of the size of the geometric shapes. If an area cannot be determined because none of the geometric shapes can be placed adjacent to the hazard location or because a subsequent (larger) geometric shape cannot be located at the previously determined areas, then the hazard location is not accessible. In other words, the danger point is only accessible if, starting from the first area, all subsequent areas, in particular the area to be determined using the largest geometric shape, can be determined. Since the first area of the first geometric shape adjoins the danger point, the danger point is accessible with the first geometric shape (in particular with a combination of the geometric shapes from the first to the largest geometric shape).
- the plurality of geometric shapes is a plurality of spheres.
- Spheres have a geometry that can be simulated relatively easily in the virtual environment. In particular, due to their spherical symmetry, calculating distances or arrangements of the sphere in the virtual environment is easier compared to more complex (less symmetrical) objects.
