Definitions
- the invention relates to the field of assembly of motor vehicle bodies. It relates in particular to the geometry of 5 vehicle bodies.
- Each type of motor vehicle requires the use of tools specially adapted to its assembly.
- the tools are installed at. remains along the assembly line, at workstation levels dedicated to a particular type of vehicle.
- 10 Solutions have been developed to allow more flexible use of workstations, with a view to reducing the area occupied by these workstations, as well as the associated operating costs and times.
- a solution called MMAC. (Modular Body Assembly Machine) or MFAC (Modular Body Assembly Machine) 15 consists of having barrels supporting a plurality of tools at the front and at the rear of the body during assembly. The barrels are rotated to select and bring a suitable tool opposite the case.
- Flexframer® Another solution known under the name Flexframer®, consists of a modular assembly consisting of a mobile carrying robot and interchangeable tools.
- the mobile robot is able to be moved in translation along the sides of the body.
- the robot is able to fetch different tools depending on the type of vehicle to be assembled and bring the tools next to the body.
- the latter solution is relatively expensive since it requires the use of robots capable of lifting and handling heavy loads. Because of the . cost generated by the equipment involved, the use of the above solutions is profitable only for large production rates (that is to say for rates of the order of 30 to 65 vehicles per hour approximately ). In addition, at such rates the equipment must necessarily be automated, which excludes the manipulation of tools by operators.
- a problem solved by the invention is to provide a more economical vehicle body assembly assembly, suitable for low and medium production rates (rates of the order of 5 to 35 vehicles per hour approximately).
- This problem is solved in the context of the present invention by means of a tool loading device for a vehicle body assembly station, comprising at least one tool loading means suitable for bringing said tool from a position of storage towards a loaded position in which the tool is opposite the body, characterized in that the loading means is arranged to allow movement of the tool in translation between the storage position and the working position in a direction substantially vertical.
- a tool storage position can be located above a loaded position and in this case, the loading means is adapted to bring the tool into the loaded position facing the body in a translation from the top to the low.
- a storage position can also be located below a loaded position and in this case, the loading means is adapted to bring the tool into the loaded position facing the body in a translation from the bottom to the top.
- the loading device thus occupies a reduced surface because the tools are stored above or below the level of the assembly station.
- the loading device can comprise a plurality of loading means, each loading means being intended to bring a given tool. An operator can thus load or remove tools depending on the type of vehicle occupying the assembly station.
- the tool loading device is installed along an assembly line, for example at a geometry station on the sides of the body.
- the loading device shown is adapted to be handled by two operators 1 and 2, each working on one side of the assembly line.
- Each of operators 1 and 2 is responsible for the geometry of one side of the body.
- the loading device comprises a rigid frame 10 having the shape of a gantry. It comprises vertical legs 11 and 12 positioned on either side of the assembly line and a cross member 13 extending between the legs 11 and 12, transverse to the direction of travel of the assembly line.
- the tool loading device also comprises two tools loading means arranged on either side of the gantry, each tool loading means being able to be actuated manually by one of the operators.
- Each of the loading means comprises a support 31 or 32 disposed on one side of the gantry 10, suspended above a location where one of the operators 1 or 2 is held.
- Each support 31 and 32 is disposed at a height predetermined above the ground 21, this height being greater than the size of an operator.
- Each of the tool loading means also comprises a pulley 41 or 42 secured to the support 31 or 32.
- the pulley 41 or 42 receives a cable 51 or 52 at one end of which hangs a tool 61 or 62 and at the other from which is suspended a counterweight element (not shown) whose mass balances the mass of the tool 61 or 62.
- the pulley 41 allows translation of the tool 61 in a substantially vertical direction. During this translation, the tool 61 is guided by a series of guide rollers arranged along the leg 11 of the frame 10.
- the pulley 42 allows a translation of the tool 62 in a substantially vertical direction. During this translation, the tool 62 is guided by a series of guide rollers arranged along the leg 12 of the frame 10. With such a loading device, each of the tools 61 and 62 can be moved into three different positions.
- a first position 101 called the upper storage position
- the tool 61 In a first position 101, called the upper storage position, the tool 61 is located above the operator 1, near the support 31.
- a second position 201 called the loaded position
- the tool 61 In a second position 201, called the loaded position, the tool 61 is located in view of the body 20.
- a third position called the low storage position
- the tool 61 In a third position, called the low storage position, the tool 61 is located below the operator 1, in the cavity 71.
- the tool 62 can be moved to a position high storage 102 near the support 32, a loaded position 202 and a low storage position 302 in the cavity 72.
- each tool 61 and 62 has a handle extending downwards which can be grasped by operator 1 or 2.
- a tool 61 or 62 is in the low storage position 301 or 302, it is located at a depth relative to the ground 21, such that it can be easily grasped by the operator 1 or 2 to be moved from bottom to top and brought into the loaded position 201 or 202.
- each tool 61 and 62 has a handle s extending upwards which can be grasped by the operator 1 or 2.
- the loading device comprises an approach means for approaching the tool 61 from the loaded position 201 towards a working position, the approach means being arranged to guide the tool 61 in translation in a substantially horizontal direction.
- the approach means comprises a wedging means (or re-tapping) fixed to the frame 10 and against which the tool 61 comes to bear when the tool 61 is in the working position.
- the loading device comprises an approach means for approaching the tool 62 from the loaded position 202 towards a working position, the approach means being arranged to guide the tool 62 in translation in a substantially horizontal direction.
- the approach means comprises a wedging (or re-tapping) means fixed to the frame 10 and against which the tool 62 comes to bear when the tool 62 is in the working position.
- the supports 61 and 62 can support a plurality of loading means (each comprising a pulley, a cable and a counterweight element) intended to bring different respective tools into the working position. Each operator can thus load or remove tools depending on the type of box occupying the geometry setting station.
- the operator 1 can remove a first tool suitable for a type A vehicle by moving the tool in a vertical translation from the working position to a high storage position 101. He can then load a second tool suitable for a type B vehicle by moving the second tool in a vertical translation from a low storage position 301 to the working position. Thanks to the presence of two high storage positions 101 and low 301, one of the two tools can be removed while the other tool is loaded. The movement of the first tool between the working position and the high storage position does not prevent the movement of the second tool between the working position and the low storage position. Conversely, the movement of the second tool does not prevent the movement of the first tool.
- the tool change operation is particularly simple.
- the tool loading device can include motorized means for setting in motion a tool for loading or approaching it.
