 Still according to another characteristic of the invention, the aforementioned reception and tilting device comprises a pivoting table for receiving a cover and for transferring the latter to two side panels forming guide rails inclined up and down in the direction of movement of the covers towards a support chute and a frame for tilting the cover into the chute in the approximately vertical position.

 According to yet another characteristic of the invention, the installation comprises a pusher with a horizontal actuation direction for moving the cover in the support chute and introducing it into a vertical compartment of a container disposed opposite the chute.

 According to another characteristic of the invention, the installation also includes a device for controlling the movement of at least one container in at least two guide rails fixed parallel to the longitudinal axis of the receiving and tilting device, and automatic positioning of each of the successive vertical compartments for storing the covers in front of the aforementioned support chute.

 The aforementioned guide rails comprise, at their upper part, a substantially U-shaped cross-section guide channel and a foil blade is fixed to the bottom of the guide channel along the same g each container comprising at least four feet lateral metal supports on the foil blade.

 Referring to FIG. 1, the installation for storing in particular the hoods of motor vehicles leaving their manufacturing press 1 comprises a conveyor belt device 2 arranged longitudinally at the outlet of the press 1, a gripping device 3 of each cover above the conveying device 2 and transporting it to a storage container C and a device 4 for receiving a cover from the gripping and transport device 3 and tilting to an approximately vertical position of the cover , with which receiving and tilting device 4 is associated a pushing device (which will be described with reference to FIG. 5) of the cover in a vertical compartment for storing the container C. As shown, the gripping and transport device 3 is disposed transversely to the conveying 2 and receiving and tilting 4 devices above them.

 The conveyor device 2 comprises, as shown in FIG. 3, two endless lateral bands 2a, 2b supported respectively by two longitudinal members 2c, 2d secured to a support frame 2e. Each conveyor belt 2a, 2b is wound at its two ends respectively on two wheels 2f mounted respectively at the two ends of the side members 2c, 2d, one of the wheels 2f being driven in a manner not shown by a motor while the other wheel is freely rotatably mounted at the end of the associated side member. Rollers 2g are arranged at regular intervals along the longitudinal members 2c, 2d, on either side of them to support and guide the strands of each conveyor belt during its movement for the transport of the covers. is associated an elevating device comprising two identical elevating members 5 arranged symmetrically to the transverse axis of the conveying device 2, only the elevating member most downstream from the outlet of the press 1 being shown in detail.

Thus, each elevator 5 comprises a cross 5a disposed transversely to the longitudinal axis of the conveyor device 2 below the two conveyor belts 2a, 2b and overflowing by its two free ends outside of each of the conveyor belts.

Two feet 5b with lifting heads 5c are mounted integral perpendicularly respectively on the two ends of the cross-member 5a. A control member 5d, in particular with a double-acting cylinder, is vertically secured to the frame 2e with the free end of its piston connected under the cross-member 5a in the middle of the latter. Guiding members 5e for the movement of the cross-member 5a and the lifting heads 5c, under the control of the member 5d, are arranged vertically on either side of this member between the frame 2e and the cross-member 5a. the control member 5d is actuated from its rest position, the cross-member 5a with the associated lifting heads 5c are moved upward in a plane perpendicular to the longitudinal axis of the conveyor device 2 to lift a part brought by the conveyor belts 2a and 2b above the corresponding lifting member, each piece of course overflowing outside the two conveyor belts in order to be lifted by the lifting heads 5c. It should be noted that only the lifting member closest to the outlet of the press 1 is used to transport the covers while the two lifting members are used to lift two floors respectively as will be described later.

The gripping and transport device 3 shown in FIG. 4 comprises a support beam 3a extending transversely above the conveyor 2 and reception and tilting devices 4 and a carriage 3b movable along the beam 3a under the -'action of a DC electric motor 3c provided with an incremental encoder for a precise movement of the carriage along the beam 3a. By way of example, the motor 3c piles up the carriage 3b on the beam 3a by means of a toothed belt (not shown), which carriage 3b moves along the beam 3a using ball bushings 3d integral with the carriage 3b and arranged on either side of a longitudinal guide beam 3al integral with the beam 3a beneath it. A portion forming a gallows 3e extends towards the ground under the carriage 3b while being integral of it. The upright portion of the stem 3e consists of two parallel bars 3el between the ends of which is pivotally mounted around a horizontal pivot axis 3e2 a plate 3e3 under the action of a control member 3e4 constituted in particular by a jack with double effect secured to the arms 3el and the rod of which is articulated in an articulated manner at its free end to a fixing point secured to the plate 3e3. On either side of the plate 3e3 are respectively fixed, for example to the using fixing screws, two crosspieces 3f at the ends of each of which is pivotally mounted about a vertical axis. an arm 3g provided in the vicinity of each of its two ends dtune pair of elements forming gripping suction cups 3hlet 3h2 connected symmetrically to the arm 3g by two rods 3i angularly spaced from one another under the arm 3g. The pivoting of each arm 3g around the vertical pivot axis 3j is carried out for example using a jack (not shown) mounted between the cross member 3f and the arm 3g. The two crosspieces 3f are fixed to the plate 3e3 so as to define an approximately right angle between them. It is understood that under the control of the jack 3e4, the assembly consisting of a crosspiece 3f, an arm 3g and suction cups of gripping 3h occupies an active or horizontal working position on one side of the beam 3a as shown in Figure 4 while the other assembly consisting of identical elements is in the inactive or vertical rest position on the opposite side of the beam 3a as shown in phantom in this same figure. FIG. 2 illustrates better schematically the active and inactive positions of these assemblies around the pivot axis 3e2. This figure also shows the beam 3a-carriage 3b assembly fixed along the b ti of the press 1 by means of a square frame 6. It should be noted that only a pair of suction cups 3h of an arm 3g, for example that shown entirely in FIG. 4, is used for gripping and transporting covers to a container
C while the four pairs of suction cups 3h are all used for gripping and transporting floors of motor vehicles as will be described later.

 Referring to Figure 5, the receiving and tilting device 4 consists of a support frame with beams 4a and crossbeams 4b joining the beams 4a and uprights 4c. The device 4 further comprises a receiving and transfer table 4d of a cover coming from the gripping and transport device 3 pivotally mounted around a horizontal pivot axis 4e in a yoke 4f secured to a support plate 4g . This plate is movable vertically under the action of a 4h control member constituted in particular by a double-acting cylinder arranged under the plate 4g and guided during its movement by two ball bushings 4i arranged vertically. under the plate 4g on either side of the cylinder 4h. A vertical bar 4j for lowering or raising the table 4d between a horizontal position for receiving a cover and a lowered position for transferring the cover is rigidly fixed under table 4d. The lower end of the bar 4j cooperates with the end of a bent lever 4k pivotally mounted around a horizontal pivot axis 4 and the other end of which is articulated at the end of a piston of a double-acting cylinder 4m secured to the frame of the device 4. This device also comprises two side panels 4n forming guide guides for a cover inclined up and down in the direction of progression of the covers towards a reception chute 7a forming part of a pushing device 7.

The sidewalls 4n are in the form of an obtuse dihedral and are arranged symmetrically to the longitudinal axis of the device 4 in extension on either side of the table 4d itself in the longitudinal axis of the device 4 A tilting device 40 in the form chassis is pivotally mounted about a horizontal pivot axis 4p in a yoke 4q. secured to a cross 4b. The tilting frame 40 pivots between a lowered position below the drop sides 4n and a raised position between the drop sides 4n under the action of a control member 4r constituted in particular by a double-acting cylinder so as to tilt a cover on the drop sides 4n in the chute 7a in an approximately vertical position. The chassis of the device 40 comprises two parallel sills 401 linked together in particular by a crosspiece 402 on which the end of the piston of the jack 4r is hingedly connected. Two heels 403 are rigidly fixed respectively on the two ends of the beams 401 opposite the pivot axis 4p. These heels come to bear under the hood on the side panels 4n-during the hood tilting operation.

 A pushing mechanism 4s is mounted in the table 4d to push a cover on the latter in the drop sides 4n during the lowering from the horizontal position of the table 4d. This mechanism comprises an endless pushing chain 4sl arranged along the longitudinal axis of the table 4d and in the lower strand of which is arranged a control member constituted in particular by a double-acting cylinder 4s2 and two pushing stops 4s3 symmetrically integral of the upper strand of the chain 4sl and protruding above the 'table 4d. The tabs 4s3 move along the table 4d in the direction of progression of the covers towards the chute 7a.

 The reception chute 7a, arranged transversely to the longitudinal axis of the reception and tilting device 4, is integral with two uprights 7b of the pushing device 7, which uprights are integral with their lower ends of side members 7c. A retaining member 7d, which can be raised and lowered by means of a control member constituted in particular by a double-acting cylinder 7e, is pivotally mounted between the upper ends of the uprights 7b in a yoke 7f. The retaining member 7d is in the form of an angle iron which folds over the upper part of a cover in the chute 7a to maintain the latter in the vertical position. The device 7 further comprises a pusher member 7g moving horizontally between the uprights 7b at their median part. The pusher member 7g is integral with a strand of an endless thrust chain whose other strand comprises a control member constituted in particular by a double-acting cylinder 7h. The pusher member 7g is located substantially vertically above the receiving chute 7a.

 FIG. 6 represents a lifting table 8 disposed substantially opposite to the beam 3a of the receiving and tilting device 4. This table, which is used to receive floors from the gripping and transport device 3, comprises a horizontal plate 8a moving vertically under the control of a double-acting cylinder 8b disposed under the plate 8a and integral with the table frame, the plate being guided during its movement by two ball bushings 8c arranged vertically on either side other of cylinder 8b.

As shown in Figure 8, each container
C hood storage comprises a number of vertical hood storage compartments defined by parallel cheeks or partitions integral with the chassis of the container. The latter moves in a direction parallel to the longitudinal axis of the receiving and tilting device 4 on two parallel guide rails 9. More specifically, the lateral metal feet C1 and C2 of the container are arranged respectively on the two upper parts of the rails 9 having a U-shaped cross section as shown in FIG. 9. The guide track 9a thus defined all along each rail 9 comprises at its bottom a foil blade 9b secured to the bottom by clamping its longitudinal sides between a support plate 9c along the actual U-shaped rail 9d and two side rails 9e using fixing screws (not shown). The bottom of each rail thus coated with the foil blade 9b allows the iron against iron sliding of the four feet of each container in the two rails 9. The "iron-iron" contact made between the rails and the feet of the container with coefficient Relatively high friction makes it possible to avoid overtravel during the movement of the container and therefore to allow a step-by-step advance thereof. In addition, the foil blades 9b make it possible to minimize the wear of the rails originating from the sliding of the feet of each container, the foil having a very high surface hardness.

 The container C is moved using an endless thrust chain 10 (see also Figure-7) driven by a direct current motor M1 and on which a pusher spout 11 is brought into abutment against a lower cross member C3 of the container C for sliding movement thereof in the rails 9 to a position for storing the covers leaving the receiving and tilting device 4 in the container. The pusher 11 consists essentially of a thrust cleat 11a pivotally mounted between two flanges ilb about a horizontal axis against a lic return spring disposed at the end of the cleat opposite to that coming to bear against the cross member C3.

 A second endless thrust chain 12 with a pusher spout 13 identical to the pusher spout 11 is also provided for moving by sliding in the rails 9 a second container C towards the first container behind it relative to the direction of movement. containers to their hood storage position. The chain 12 is also driven by a DC motor M2.

 The device for controlling the movement of each container C in the rails 9 is associated with an automatic positioning device for each of the successive vertical compartments for storing the container opposite the outlet of the chute 7a of the pushing device 7. This control device is essentially constituted by a cell 14 for detecting the passage of each vertical compartment to be filled with the container, which triggers the stopping of the associated push chain of the container after detection of the passage of the vertical compartment to be filled opposite the chute 7a. The cell 14 is of the direct reflection type, that is to say that the ray emitted by the cell is returned to the latter by the object to be detected, in this case the cheeks of the vertical storage compartments and is connected to counting means (not shown) including cheeks.

 The operation of the device for controlling the movement of a container and positioning it in the storage position will be described with particular reference to FIGS. 7 and 10.

In the starting position designated by the arrow D in FIG. 7, the pusher 11 of the chain 10 comes to bear on the cross member C3 of the container C which was initially placed in the rails 9 in the starting position. The chain 10 moves the container C in the direction indicated by the arrow A in FIG. 7 to bring it towards the loading position until the cell 14 detects the lateral foot C1 of the container. For understanding, it is assumed that the compartment to receive a cover will be that defined between the cheeks a and b of a limited succession of cheeks an. After detection of the foot C1, the chain 10 continues its action of pushing the container in the direction A until the cell 14 detects the cheek b. An order to stop the chain is then given and it stops when the cell 14 targets the space between the cheeks b and c At this time, the chain 10 and the container C are immobilized so that the compartment defined between the cheeks a and b is located opposite the loading axis of the device 4 defined by the chute 7a. The cover which is waiting vertically in the chute 7a is then introduced into the compartment between the cheeks a and b using the pusher member 7g of the pusher device 7. When the jack 7h has moved the member back pusher 7g in the position shown in FIG. 5, the chain 10 is put back into service until the cell 14 detects the cheek c and the stop order is then given to the chain 10 which stops when the cell 14 is aimed at the space between the cheeks c and d so that the compartment defined between the cheeks b and c is opposite la.goulotte 7a. A new cover is then introduced into the compartment between the cheeks b and c by the pusher member 7g and the process of positioning the compartments in front of the chute 7a and of loading them continues as described above until container C is completely filled with covers. Before the container C is filled, a second container C 'is put in place at the starting position D and the chain 12 is put into service to push the container C' a few centimeters behind via the pusher 13 the container C. When the container C is filled, the chain 10 evacuates the container C to a stop BU at the end of the rails 9. The container C ', pushed by the chain 12 will then have taken the place of the container C in front of the cell 14, the process of positioning and loading the compartments of the container C 'being identical to that described with reference to the container C. When the container C arrives abutting against the stop BU, the chain 10 is stopped and the engine M1 is' actuated so as to bring back or move back the pusher 11 towards the starting position
D leaving the container C abutting against the stop BU, which container will be removed later by a handling machine.During this movement back to the starting position D, the pusher 11 can be erased by passing under the container C 'due to the pivoting movement of the thrust cleat against the return action of the spring llb. Once at the starting position D, the chain 10 will push a new container previously placed in the rails 9 behind the container C 'during loading. When the container
It is filled, it is brought by the chain 12 abutting against the stop BU while the third container has taken the place of the container C 'in front of the cell 14. The process of positioning and loading of the containers is also repeated as long as necessary as described above.

 The operation of the installation for storing the covers in the containers C is already apparent in part from the description which has been made thereof and will be described in more detail below with reference also to FIG. 11.

The cover CP leaving the press 1 is fitted. on the two-belt conveying device 2 which transfers it to the top of the lifting member 5 near the outlet of the press 1. The lifting member 5 raises the cover CP above the conveyor belts 2a,
2b until caught by a pair of suction cups
3hl gripping, including the 3g arm, arranged in parallel
to beam 3a, is lowered if necessary by ordering
the cylinder 3e4 ensuring the pivoting of the plate 3e3. A
Once the cover CP has been taken, the electric motor 3c moves the
carriage 3b on the beam 3a towards the device for
reception and changeover 4. During the movement of the
carriage 3b, the cover CP is pivoted about 900 around
de- the pivot axis 3j so that the arm 3g is perpendicular to the beam 3a. The pivoting movement of 900 of the cover CP is illustrated in FIG. 11 by the arrow B. At the end of its travel, the carriage
located above the receiving and tilting device 4 and the gripping suction cups 3h release
the cover CP on the device 4, including the table
reception and transfer 4d is in the horizontal position. It should be noted that the fitting of the cover CP on
the 4d table can be made if necessary by lowering
gripping suction cups 3h above the table. The 4m cylinder is actuated to control the lowering of the table 4d to approximately 450 with respect to the horizontal and the 4s2 cylinder is also actuated to push the cover CP
in the sideboards 4n by means of the pushing pins 4f3; The ch ssis rocker 40 is then actuated by the control cylinder 4r to be raised so as to tilt the cover CP to an approximately position
vertical in the chute 7a, the retaining member 7d,
which was raised, being folded over the cover CP to ie maintain between the chute 7a and the member 7d.

The pusher member 7g is actuated by the jack 7h to push the cover CP which slides in the chute 7a, and
place it in a vertical storage compartment
of the container which has been precisely positioned opposite
of the chute 7a in the manner already described above.

Once the cover CP has been loaded into its appropriate compartment, the pushing chain 10 or 12 advances the stacker by one step so that the next empty compartment is positioned opposite the outlet of the chute and the storage process above described of a cover CP in its compartment repeats.

 The hood storage installation according to the invention has the advantage of monitoring the rate of manufacture of the hoods at the outlet of the press 1. In fact, while the gripping and transport device 3 takes up a cover of the conveying device 2 , the receiving and tilting device 4 is loading another cover into the container C. The various devices of the installation of the invention pass a cover from one to the other, which makes it possible to transfer the cover from a distance of, for example, 2.35 m by pivoting it by 900, transferring it to the receiving and tilting device 4 and loading it into a container C, this at an output rate of approximately 10 covers The existence of the two push chains 10 and 12 makes it possible to bring an empty container behind the container which is being loaded, which is immediately replaced as soon as full.

 The above-described installation can also be used to store motor vehicle floors in suitable containers.

 For this, the installation shown in FIG. 12 comprises the same devices as the installation in FIG. 1, namely the press 1, the conveying device 2, the gripping and transport device 3, the receiving and tilting 4, the only differences being in the additional use of the lifting table 8 and two containers P, P 'arranged at the end of the travel of the carriage 3b substantially on either side of the beam 3a. The containers P and P 'are simply placed on the ground and are intended to be filled with floors positioned horizontally on top of each other.

 The process of storing floors in containers P and P 'is as follows.

 -The first PL1 outgoing floor press 1 is raised by the lifting member 5 closest to the outlet of the press 1 and is pressed under the gripping suction cups 3hl. The device.4 playing the role of a lifting table like the table 8 is also raised at the same time as the lifting member 5, no floor being yet placed on the device 4. The carriage 3b moves towards the container P until the gripping cups 3h2 are above the container P and the gripping cups 3h1, carrying the floor PL1, are above the device 4. At this position, the gripping cups 3hl release the PL1 floor on the table of the device 4. The carriage 3b is then controlled so as to return to its initial position, that is to say to the position where the gripping suction cups 3hl are located substantially in the axis of exit of the press 1 floors, with the suction cups 3h2 above the PL1 floor placed on the device 4. The second PL2 floor leaving the press 1 is raised by the lifting member 5 while the floor-PL1 is simultaneously raised by device 4 so that the p Lanchers PL2 and PL are pressed respectively under the gripping suction cups 3hl and 3h2. The carriage 3b then moves again towards the container P with the two floors PL1 and PL2.

At the end of the race, the floor PL1 is located above the container P and the floor PL2 is located above the device 4. The gripping suction cups 3hl and 3h2 release the two floors PL1 and PL2 so that the floor PL1 falls in the container P and the floor PL2 is placed on the device 4. The carriage 3b then returns to its initial position as before to repeat the above process to bring the second floor PL2 into the container P and a third floor on the device 4 and so on.

 When the container P is filled with floors, the cross member 3f located on the side of the press 1 is raised to an approximately vertical position while the cross member 3f opposite the press 1 on the other side of the beam 3a is lowered concomitantly at an approximately horizontal service position, the carriage 3b having of course been returned to its initial position before then filling the container P ′ with floors according to the same process as that described above for filling the container P. FIG. 12 represents in dotted lines the floor PL3 raised by the table 8 to be pressed under the corresponding gripping suction cups and the floor PL4 raised by the lifting member 5 to be pressed under the corresponding gripping suction cups.

 When the container P 'is full, the cross member 3f opposite to that located on the side of the press 1 is then raised to the vertical position while the other cross member 3f is brought to the horizontal service position and the floor storage process in a new container P repeats as described above. Of course, during the transfer of the floors to the containers P, P 'each arm 3g occupies a position parallel to the beam 5a.

 The storage installation according to the invention has been described with reference to hoods and floors of motor vehicles but it is obvious that it can be easily used and / or transformed to store other parts vertically or horizontal.

 It should also be noted that the logic circuit necessary for automatically controlling and / or controlling the above-described processes of conveying, transferring the parts and positioning the containers relative to the receiving and tilting device 4 can be easily achieved. by a person skilled in the art on reading the operation of this installation.
