Definitions
- the invention relates to the design and implementation of an industrial manufacturing line. She is interested in the assembly of mechanical parts, including - but not only - in the automotive field.
- assembly lines for manufactured products generally consist of a succession of manual or automatic assembly stations.
- Automatic type assembly stations use special, dedicated machines designed specifically for a given type of product ("product type” means a family of products and its variants), and for a given production capacity.
- the invention then aims to design new production lines that are more flexible, especially in terms of the type of product manufactured and in terms of variation of production rates. It aims in particular to overcome the aforementioned drawbacks.
- the invention firstly relates to an industrial production line comprising manual and / or semi-automatic and / or automatic assembly stations, such that said assembly stations are broken down into standardized modules, which are each operated manually or automatically or semi-automatically operating interchangeably, in particular depending on the production capacity.
- the invention thus proposes a new way to modularly design the assembly of products, by breaking down the assembly stations into simple subsets, standardized and flexible modules. These modules make it possible to carry out manually or automatically the various assembly operations.
- the production line is formed by juxtaposing the different modules, according to the type of product to be assembled and the production capacity to be achieved. Each module corresponds to an elementary operation to be performed.
- the standardized modules of an assembly station preferably operate successively and / or in parallel: several operations can be carried out in parallel, for a final assembly for example, which allows a saving of time .
- the standardized modules with automatic or semi-automatic operation are equipped with robotic means provided with integrated security means, in particular so-called security means on unintended contact.
- the standardized modules with automatic or semi-automatic operation are equipped with robotic means provided with sensors with feedback on each of their mobility axes.
- This type of robot belongs to a new generation of robots, sometimes called “safe” (safe in French), because designed to be able to conduct operations in a human environment without external security device, thanks to their integrated security , including appropriate sensors: there is no need to use isolated robots, "caged”, to protect operators, nor is there any need, in fact, to consolidate manual operation in one area, and the robots in another. And the integration of sensors on each of their mobility axes, beyond their purpose for the safety of the operators, makes it possible for them to carry out tasks with a very precise sensory feedback.
- This type of robot also has the advantage of being generally very compact, with a size close to the human size, which makes them easily implantable / integrable on the production line.
- an assembly station may comprise at least one manual standardized module and at least one standardized semiautomatic or automatic module.
- Each of the stations can combine, depending on the product and the desired production, fully manual, partially manual (semi-automatic) or fully automatic (robot-only) modules.
- the invention also relates to the use of the industrial production line described above to the assembly of mechanical parts, including the assembly of members belonging to a powertrain, for example a powertrain vehicle in particular terrestrial type motor vehicle.
- the invention also relates to a method for implementing the industrial production line described above, the method decomposing the assembly into a series of elementary operations in a predetermined unit of time, each operation being carried out by a standardized module.
- the method of the invention is thus structured in elementary operations according to a unit of time u t , which can be for example 30 seconds.
- a unit of time u t which can be for example 30 seconds.
- Each operation can be performed by a "brick” function, all of these "bricks” composing a library of manual, semi-automatic or automatic functions interchangeable.
- bricks can be juxtaposed (in series) in a workstation to compose a workload of N xu t .
- the organization of the bricks can also make it possible to carry out operations in parallel (in masked time).
- the organization of the bricks in series and / or in parallel makes it possible to adapt the construction of each cycle work station of the line which is aimed at.
- the unit of time u, predetermined is chosen between 10 seconds and 2 minutes, and may be in particular of the order of 30 seconds.
- the method according to the invention uses the production line to assemble different products by a reorganization and reprogramming of the standardized modules.
- the invention also relates to a method of operating an industrial production line comprising manual and / or semi-automatic and / or automatic assembly stations, such that said assembly stations are decomposed into modules.
- standardized which are each manual operation or automatic operation or semi-automatic operation and as we choose the relative number of manual modules, semi-automatic and automatic, which are interchangeable with each other, depending on the production capacity.
- this method performs assembly operations using robotic means provided with integrated security means interacting with human means. It is thus possible to use non-sterile robots that will cooperate with operators on the same line, with a direct proximity between robot and operator.
- the relative proportion of robotic means of this type and of operators is adjusted absolutely flexibly according to the rate of production required, the interchangeability between operators and robotic means being complete.
- each standardized module is dedicated to a given elementary operation, and the assembly of the parts is modified by adding / removing standardized modules. It is thus possible to quickly adapt / reconfigure the production line according to a modification / evolution of the product to be assembled, or according to the different variants of the product to be assembled.
- FIG. 1 shows a production line according to the state of the existing art and a modified production line according to the invention
- FIGS. 2, 3 and 4 respectively represent, for the same assembly station of a production line according to the invention, a manual module (FIG. 2), a semi-automatic module (FIG. 3) and an automatic module.
- Figure 4 FIGS. 5, 6 and 7 show, respectively, for a same assembly station of a production line according to the invention, a semiautomatic module according to a variant a (FIG. 5), according to a variant b (FIG. ) and an automatic module ( Figure 7);
- FIG. 8 is a graphical representation of the flexibility of a production line according to the invention as a function of a request for an increase in production capacity
- FIGS. 9 and 10 show a sealing control station of a production line respectively according to the state of the art existing (FIG. 9) and according to the invention (FIG. 10);
- Figures 1 1 and 12 show a screwing station of a manufacturing line respectively according to the state of the art existing ( Figure 1 1) and according to the invention ( Figure 12);
- FIG. 13 is an illustration of a flexible manufacturing line according to the invention.
- Figure 1 shows in the largest view a manufacturing line of the state of the art, with a portion of an assembly line L1 of mechanical engine parts.
- the line portion L1 here has the approximate shape of a U.
- operators 1 surrounded by an oval for better locating on the figure
- robots 2 arranged in safety cages 3 also all arranged successively.
- the line is designed to group workstations with manual operations on one side and workstations with automated operations on the other. Automated stations take up a lot of space, and it is understood that this type of manufacturing line is not very flexible, compact and requires the design of operations not in the most rational way because of the sharing of the line between manual and automated operations.
- Figure 1 also shows, in the smallest view, the modifications made by the invention with respect to the existing line, namely a redesign of the line to make the same assembly more efficiently.
- Line L2 comprises a succession of manual and automatic workstations, the organization of which is controlled by the rationality and minimization of the movements of operators and products being assembled. We see that between two operators, we have at most 2 meters distance, while in the previous case, we could have up to 10 meters between two operators.
- Robots 2 with safety for the operators in the form of cage 3 are here replaced by 2 'robots of much smaller size, and equipped with integrated security means using sensors and which avoid any risk of accident by unintentional contact with a operator, and which makes it possible to dramatically compact the production line.
- the degree of automation of each workstation is best adapted to the needs, according to the volume of production required, by exchanging a manual position by a semi-automatic or automatic station, without the dimensions of the line being significantly impacted.
- the line can remain compact, keep given dimensions even if the rate of production changes drastically.
- FIGS. 2 to 4 show the design of an interchangeable workstation according to the invention for the same series of elementary operations to be performed:
- FIG. 2 represents a manual work station, with two operators successively carrying out manual operations, possibly with tools, on a product being assembled 4 traveling on a conveyor from one operator to the next.
- FIG. 3 is a workstation performing the same series of elementary operations, but which is semi-automated: we have added "plug and play" automated tools to designate, in French, robotic tools 5, 5 'that it is enough to connect mechanically and electrically and to program to support the operations made by the operator, either to do some of the elementary operations in its place, or to help make them faster / easier.
- Figure 4 is a fully automated workstation: all the elementary operations are performed by robotic tools 5,5 '.
- FIG. 5 shows, respectively for a same assembly station of a production line according to the invention, a semi-automatic module according to a variant a (FIG. 5), according to a variant b (FIG. 6) and an automatic module (FIG. 7):
- FIG. 8 is a graphical representation of the flexibility of a production line according to the invention as a function of a request for an increase in production capacity: for a given production line, the arrow F1 indicates a direction. to increase the investment in industrial equipment, the arrow F2 indicates a direction of increase of the degree of automation of the line (M meaning that the operation is manual, and A that the operation is automated).
- A1 represents a first level of production, for example N produced per year
- A2 a second production level, for example 1.5 x N produced per year
- A3 a third production level, for example 3 x N products. per year, with the same workstation S to perform three basic operations, which can be manual or automated.
- the adaptation of the production tool to the product is therefore conducted mainly by programming, with the possible simplification of tools to easily consider tool change solutions without fundamental redesign of the manufacturing process.
- This flexibility makes it possible to better load the production lines by making them capable of manufacturing several types of product easily, and to be generally less sensitive to changes in the volume of sales of the products manufactured.
- Figures 9 and 10 show a sealing checkpoint of a product on a production line respectively according to the state of the art ( Figure 9) and according to the invention ( Figure 10): to Figure 9, we see a robot 2 in a safety cage 3 to perform this verification, while in Figure 10 the robot 2 has been replaced by a robot 5 '"safe", with a dramatic space saving.
- FIG. 13 represents a production line which, for a given production rate, has adopted the most appropriate configuration between semiautomatic modules A, manual modules C and automatic modules B: here there are 5 modules A, 1 module B and 1 module C. If the rate had to change (or if the number and / or the succession of elementary operations had to change), one can quickly reprogram the line by modulating the relative number of these three types of module.
- the invention uses modular machines to compose a manufacturing process at variable rate by simplified reconfiguration, it uses elementary means allowing flexibility to the product by programming. It makes it possible to better spread the investments on the industrial tool, and to manufacture several families of products on the same line. It shortens the development time, commissioning and reconfiguration of line. It makes it possible to conserve the cycle time of the existing processes, and a great gain in time over the industrialization time, due to the use of standard "bricks".
