Definitions
- the present invention relates to a mounting station arrangement suitable for assembling different references of parts to be assembled to different variants of subassemblies for a motor vehicle.
- the assembly of subsets such as the rear trains of motor vehicles, is generally done on assembly lines comprising conveyors on which the different parts of each of the subassemblies are assemblies.
- the work on these assembly lines is characterized by the pace of the work steps, the conveyors advancing for example with a speed of 2.5 m / min.
- the operator having only a few seconds to identify the version of the subset arriving in front of him and then to take the compliant part among this plurality of parts, the time may be short for the operator to check if he has really mounted the piece in its good reference.
- a first approach to avoid such errors was to mark all the different parts, constituted for example by the brake discs of different variants of a rear train, a label with a bar code ensuring compliance with the rear train to get.
- this solution first required printing and pasting labels on each of the brake discs and then asked the operator to take the barcode reader, read the codes of two or sometimes more brake discs to find the correct disc for the rear gear to be prepared and remove the bar code reader before you can start editing. It is advantageous to dispense with these labels and nevertheless avoid assembly errors of parts such as brake discs.
- the object of the invention is to provide a solution that makes the assembly more reliable while optimizing the assembly time.
- the object of the invention is achieved with a mounting station arrangement suitable for assembling different references of parts to be assembled to different variants of subassemblies for a motor vehicle, comprising a supply cabinet of different references parts, means for identifying the current variant of the subassembly to be assembled in the mounting station, means for indicating to an operator the current part reference to be taken from the cabinet for mounting the current variant of subassembly, and means for faulting assembly line in the event of sampling, the supply cabinet, a part whose reference is other than the part reference indicated.
- the invention also relates to the following additional features:
- the means for indicating the current item reference to be taken from the supply cabinet comprise lamps mounted on the piece of furniture according to the arrangement of the pieces, and a unit for processing a signal representing the identity of the subassembly and generating a control signal that lights the lamp indicating the part to be taken;
- the faulting means of the assembly line comprise sensors arranged on the supply cabinet and adapted to generate a fault signal when a non-compliant part of the current variant of the subassembly is taken from the furniture of supply, means for stopping the assembly line, a unit for processing the fault signal and generating an activation signal for the stop means of the assembly line and a lamp mounted on the cabinet of supply indicating fault in the assembly line;
- the lamp indicating the fault of the assembly line emits a light of a second color different from the first color of the lamps signaling the parts to be taken.
- the object of the invention is also achieved with a supply cabinet for the provision to an operator of different parts references for different variants of a subassembly, the furniture comprising for each reference pieces to mount a storage track adapted to the reference parts that must be arranged.
- the invention also relates to the additional features below: - the cabinet is provided with a lamp mounted in correspondence of each of the storage tracks, the lamps being connected to a unit of processing a signal representing the identity of a carrier carriage of a subassembly and generating a control signal causing the lamp to light indicating the part reference to be taken according to the variant of the subassembly; -
- the storage tracks have different useful widths according to the part reference intended to be arranged.
- the invention also relates to a mounting station suitable for assembling different references of parts to be assembled to different variants of subassemblies for a motor vehicle, wherein is installed an arrangement as described above and wherein assembly line carriages are dedicated to transport the subassemblies, the identification means of the current variant of the subassembly to be assembled in the assembly station comprising an identification plate fixed to each of the carriages and a reader of these plates.
- the identification plates of the carriages comprise perforations representing in coded form the identity of the subassembly adapted to be transported by the carriage.
- FIG. 1 schematically represents a section of assembly line and having a mounting station provided with several work stations and the arrangement of the invention
- FIG. 2 represents means for identifying a carriage of the assembly line of FIG. 1
- FIG. 3 shows a rear axle of a motor vehicle as an example of a subassembly assembled on a mounting line of FIG. 1,
- FIG. 4 is a perspective view on a supply cabinet of different references of brake discs for the rear axle of FIG. 3;
- FIG. 5 is a perspective view on part of the refilling side of the supply cabinet of FIG. 4,
- FIG. 6 is a view in another perspective on the part of the furniture shown in Figure 5.
- Figure 1 shows a mounting line 1 used, by way of non-limiting example, for assembling different variants of a rear axle or other subset of a motor vehicle.
- the assembly line 1 comprises carriages 2 each carrying, according to the example chosen, a rear axle 3 being assembled on the base of a crosspiece 31.
- the carriages 2 pass successively in front of an operator CH assigned to the loading of a cross member 31 on each of the carriages 2, operators located at unrepresented work stations where first elements are mounted on the crosspieces 31 and operators OP1, OP2 assigned mounting different references of brake discs 4 respectively left and right on the cross members 31.
- each of the operators CH, OP1 and OP2 and the carriage 2 which it has in front of it correspond to a work station of the assembly line 1 and thus to a work step of the method of assembling the rear axle 3.

- the mounting station further comprises a supply cabinet 8 on which the brake discs 4 in their different references are made available to operators OP1, OP2.
- the brake discs 4 are arranged according to their diameter and possibly according to another criterion, for example the type of hub, by which the variants of the rear axle 3 are distinguished from each other. Indeed, the rear trains 3 are intended for vehicles of the same type but different engines.
- the size of the brake discs being related to the power of the engine of a vehicle, it is obvious that a disc too small compared to the planned disc could penalize the braking benefits and too large a disc could also pose problems for example for mounting the vehicle wheels which could then be too small.
- the supply cabinet 8 has a storage and storage surface formed by a plurality of tracks 81, parallel to each other, the useful width corresponds to the diameter of the brake discs 4 that they must receive.
- Each of the tracks 81 extends between a delivery or sampling face 82 of the furniture 8, oriented towards the carriages 2 and on which the operators OP1, OP2 take up the brake discs 4, and a loading face 83 of the furniture 8, opposite the distribution face 82.
- the supply cabinet 8 is provided with as many lamps 9 as the furniture comprises tracks 81.
- the lamps 9 are connected to and controlled by the electronic device 7 and emit a light of a first color, preferably a green light, to indicate the track (s) on which (or which) the operator must take the brake disc 4 according to the variant of rear train to obtain.
- the supply cabinet 8 is provided with a lamp 10 also connected to and controlled by the electronic device 7 and emitting a light of a second color, preferably a red light, when the operator has not taken the disc from the track indicated by the lamp 9.
- a lamp 10 also connected to and controlled by the electronic device 7 and emitting a light of a second color, preferably a red light, when the operator has not taken the disc from the track indicated by the lamp 9.
- the assembly line 1 finally comprises means for faulting the assembly line 1 which are connected to and controlled by the electronic device 7 when one of the operators OP1, OP2 takes a brake disc 4 other than that (or those) indicated by one (or more) of the lamps 9.
- Figure 2 shows a portion of a carriage 2 on which is fixed the identification plate 6 of the carriage and a part of a work station of the assembly line 1 on which is mounted one of the reading stations 5 adapted to read the identification plates 6 of the carriages 2.
- the identification plate 6 has perforations or slots 61 representing the number of the carriage in a code.
- the reading station 5 comprises a bottom plate 51 with means 52, luminous or not, forming a bottom white, and a support 53 with a reading device 54.
- the reading device 54 is spaced from the means 52 so that the identification plate 6 can pass between the device 54 and the means 52 to be read.
- Figure 3 shows a subassembly consisting of a rear axle 3 being mounted with two labels 32, 33 glued on the cross member 31 of the rear axle 3.
- the label 33 includes information on the specific vehicle configuration which the rear gear 3 is intended. This information comprises the only two indications reproduced on the label of FIG. 3, namely the sequence number 34 of the vehicle to be manufactured and the indication of the type of brake disc 4, or brake disc reference, to mount on the rear axle 3.
- Figure 4 shows that the supply cabinet 8 essentially comprises, mounted on a support 85 for placing the supply cabinet 8 next to the assembly line 1, the tracks 81 for the provision of parts constituted by the brake discs 4, the lamps 9 indicating the brake discs 4 to be taken and mounted, the lamp 10 indicating a fault in the mounting line 1, and mechanisms 84 facilitating the capture and removal of a brake disc 4 by an operator.
- the tracks 81 have different useful widths depending on the diameter of the brake discs 4 they must receive.
- the number of tracks per width and the number of widths depend on the quantity ordered of each of the variants of the rear axle 3 and can therefore change during the manufacture of the rear trains 3. For this reason, it is advantageous to give to the tracks 81 the same external width L and removably mount on the support 85.
- the supply cabinet 8 may have a width large enough to include the tracks 81 for two successive workstations, as in the example of Figure 1, or a width for the tracks 81 for a single work station, as in the example of FIG. 4.
- the object of the invention being to avoid mounting, on a predetermined variant of a rear axle 3, brake discs 4 not in accordance with this variant of said rear axle, the means and arrangements described so far can only be effective if the CH operator was not mistaken in loading the tracks 81 of the furniture 8.
- the tracks 81 are constituted at their entrance, that is to say on the side of the loading face 83 of the supply cabinet 8, by staggered section sections having three different levels of support, namely a level by diameter of the different brake disc references provided.
- the track 81 A is intended for brake discs 4 having a diameter of 249 mm
- the track 81 B is intended for brake discs 4 having a diameter of 268 mm
- the track 81 C is intended for brake discs 4 having a diameter of 290 mm.
- the track 81 A is formed by two sections 81 1, 812 arranged symmetrically with respect to a longitudinal axis of the track 81 A.
- Each of the two sections has a lower level of support AA of a width LA1, a level intermediate BB with a width LB1 and an upper support level CC with a width LC1, the widths LA1, LB1 and LC1 being measured in the transverse direction relative to the length of the profile.
- the two profiles 81 1, 812 are mounted parallel to each other and at a distance from one another so that brake discs 4 with a diameter of 249 mm can be supported on the level BB support.
- the other discs that is to say those with a diameter of 268 mm or 290 mm, will remain on the level of DC support and it will only be the brake discs 4 of the BB level that will be advanced on the 81 A track, shown shaded in Figure 6, to the distribution face 82 of the supply cabinet 8.
- the track 81 B is formed by two sections 813, 814 disposed symmetrically with respect to a longitudinal axis of the track 81 B.
- Each of the two sections has a lower level of support AA of a width LA2 different from the width LA1, an intermediate level BB with a width LB2 different from the width LB1 and an upper support level CC of a width LC2 different from the width LC1, the widths LA2, LB2 and LC2 being measured in the transverse direction relative to to the length of the profile.
- the two profiles 813, 814 are mounted parallel to each other and at a distance from one another so that brake discs 4 with a diameter of 268 mm can bear on the level of 'support BB.
- the 249 mm disc will then pass through the BB level and the 290 mm disc will remain on the DC support level and only the BB level 4 brake discs will be advanced on the track 81 B, shown in gray. in Figure 6, to the distribution face 82 of the supply cabinet 8.
- the track 81 C is formed by two sections 815, 816 arranged symmetrically with respect to a longitudinal axis of the track 81 C.
- Each of the two profiles has a lower support level AA of a width LA3 different from the widths LA1 and LA2, an intermediate level BB of a width LB3 different from the widths LB1 and LB2 and a level of upper support CC of a different width LC3 of widths LC1 and LC2, the widths LA3, LB3 and LC3 being measured in the transverse direction relative to the length of the profile.
- the two sections 815, 816 are mounted parallel to each other and at a distance from each other so that brake discs 4 with a diameter of 290 mm can bear on the level of BB support.
- the other discs that is, those with a diameter of 249 mm or 269 mm, will fall through the level BB on the level of support AA and it will be only the brake discs 4 of the level BB which will be advanced on the track 81 C, shown shaded in FIG. 6, towards the distribution face 82 of the supply cabinet 8.
- a carriage 2 arrives at the work station of the operator CH, where the latter loads a cross-member 31 on the carriage 2.
- the label 33 indicates, among other information, in the form of a bar code, the number sequence of the vehicle to be manufactured and, in the form of the letter "A", the type of brake discs 4 with which the rear gear 3 must be equipped.
- the operator CH stores the information of the label 33 and the number of the carriage 2 in a memory of the electronic device 7 or in a central memory to which the electronic device 7 has access. Then, the carriage 2 continues its journey from workstation to workstation.
- the reading station 5 When the carriage 2 enters the workstation of the OP1 operator, the reading station 5 reads the number of the carriage 2, which is, according to the example of Figure 2, the number "06". The reading station 5 sends a signal corresponding to this information to the electronic device 7 which reads in its memory, or in the central memory, that the rear axle 3 transported by the carriage No. 06 must be equipped with brake disks 4 of type A. Also reading in this memory, which track 81 the AP operator has arranged the type A brake discs, the electronic device 7 lights the lamp 9 located directly above the track 81 concerned.
- an error signal is sent to the electronic device 7 by a sensor or a contact located on the track 81 or actuated by the mechanism 84 by means of which the brake disc 4 is taken.
- the error signal triggers in the electronic device 7 at the same time the generation of a stop signal and the sending thereof to the control of the assembly line 1, the generation of an extinction signal for the lamp 9 and the generation of an ignition signal for the lamp 10 which then signals the fault of the assembly line 1.
- the present invention provides the assembly of rear trains 3 a time saving since there are more markings to read on the brake discs 4 and a financial gain due to the removal of the labels on the discs. brake.
- the identification means of the subassembly variants constituted by the different variants of the rear trains may be of various automated type of technology including, for example, automatic readers for the labels in a different embodiment of the plate identification means. on the trolleys.
