Definitions

• the present invention relates to the design and production of overhead conveyors such as those which ensure the transport of objects along conveyor chains where these objects circulate in series through a processing installation, however they are individually suspended from one or more several conveyors describing parallel paths, from a loading station for taking charge of each object by pendulums or pendulum suspension arms linked to the conveyor, to an unloading station where they are freed.
• the invention aims to improve the operating conditions of robotic industrial sites involving such conveyors, in particular by authorizing high production rates thanks to better performance of transport facilities in speed and flexibility, while allowing great robustness ensuring operational safety, for infrastructure investments and reduced maintenance costs.
• it includes in particular that of limiting the size of the installations as much as possible, that of simplifying the procedures implemented at the loading and unloading station, that of favoring construction parameters and conditions of operation ensuring high durability by avoiding wear of moving parts.
• the invention relates more specifically to conveyors intended for installations in which the objects are conveyed suspended by pendulum arms with two symmetrical conveyors which run through the installation under the control of synchronized drive means, more particularly still targeting as nonlimiting, installations where each load is suspended from the two conveyors on the one hand at the front, on the other hand at the rear.
• each charge can be constituted directly by one of the objects to be conveyed, but that it can also consist of an assembly comprising this object and an appropriate support on which it rests, the support being chosen in particular compatible with conveyors, in particular with the pendulum arms which they comprise.
• each body is suspended by two pendulums, one arranged at the front and the other at the rear in the direction of transport and each one being formed in one piece by means of a transverse bar making two vertical arms integral, respectively clinging to the tractor means of the two conveyors, and the embodiments where the pendulum arms are no longer connected in a rigid assembly and where each load to be conveyed in the installation, along a predefined conveyor line, is suspended from two symmetrical conveyors by four independent pendulum arms, two by conveyors.
• the invention is of particularly significant interest in the case where, in order to avoid providing clutching and disengaging devices for the load suspension arms at the loading and unloading stations at the ends of the line.
• conveying these arms are permanently mounted, in fixed positions regularly distributed over the tractor means of the conveyor (s), and where these tractor means are driven in translation on themselves in a closed loop circuit, comprising a portion of the forward circuit traversing the conveyor line from the loading station to the unloading station and a portion of the so-called return circuit because the load suspension arms circulate therein empty to return from the unloading station to the loading station in order to capture a new charge.
• the invention lends itself particularly well to situations which involve such a closed loop circuit lying entirely in the same vertical plane and where, moreover, the return portion of the vacuum arm is arranged, in this plane, above the outward portion which ensures the transport of loads along the conveyor line.
• overhead conveyors of the type considered within the framework of the present invention are particularly appreciated for ensuring the transport of the bodies of motor vehicles according to circuits implying uneven sections, when in particular the bodies must be immersed in treatment baths in tank as we find in the lines of painting by phosphating or the lines of caraphoresis or other electrolytic treatment, owing to the fact that the circuits which traverse the means tractors of the conveyors comprise changes of slope in slope in a vertical plane, from where l interest of closed loop circuits also remaining entirely in the same vertical plane. Indeed, it is desirable that throughout their journey the tractor means work in the curved areas always in the same plane. This technological requirement is particularly sensitive when the towing means are cables kept stretched on guide wheels between which the loads are exclusively carried by the cable or cables by means of the arms ensuring their suspension.
• the invention is essentially concerned with equipping the conveyor, or each conveyor of such an installation, with means for controlling the orientation arms throughout this circuit.
• the invention plans to organize their circulation in such so that, when they return empty from the unloading station to the loading station to take a new load there, they orient themselves in a position where they are individually folded down along the circuit of the tractor means, in its so-called return portion, advantageously until it comes to rest on receiving members integral with said tractor means.
• the invention also provides means by which, during a complete journey of the closed-loop circuit, each arm is made to execute a complete revolution in space, by rotation of a half-turn around its proximal end to which it is linked to the towing means, between the moment when it is vertically hanging at the outlet of the unloading station and the moment when it is again vertically hanging at its arrival at the loading station.
• Each arm is for this purpose fixed to the tractor means, at its end called here proximal, by an articulated assembly device allowing it to pivot freely in the vertical plane of the path of the tractor means, around a perpendicular axis of articulation. to this plane.
• the different load suspension arms are guided at a distal end remote from said proximal end, to cause their tilting around the axis of articulation of the assembly devices respectively associated from their orientation in the folded position along the circuit in its return portion until it is in the vertical pendant position when approaching the loading station.
• the tilting of the arms is advantageously ensured by a pivoting movement of each arm (around the axis of articulation of the assembly device between the suspension arms and the tractor means) on substantially a quarter turn at the exit from the unloading station, to go from the vertical orientation to the orientation in the folded position on the circuit, preferably substantially horizontal (the distal end being late with respect to the proximal end), and by a tilting movement of each arm, where its distal end passes over its proximal end, describing three quarters of a turn, when approaching the loading station.
• the invention will be described with reference to a loading station and an unloading station which is arranged with respect to the organization of the circulation of the arms in accordance with secondary characteristics of the invention, in its modes of preferred implementation, but it must be admitted that its main characteristics would be just as valid if the functions of the loading station and the unloading station were reversed at both ends of the transport loop. It also falls within the scope of the present invention to suspend the loads to be transported either on a single conveyor or on two symmetrical conveyors situated in parallel vertical planes, as well as to provide one, two or four independent arms for each load, as soon as the arms remain articulated in fixed positions regularly distributed over the tractor carrying means and the loads are individually picked up at the loading station to be deposited at the unloading station.
• Various characteristics of the invention relate to the production of the tractor means of the conveyor, or of each conveyor, in connection with the support members receiving the pendulum arms in their folded position and with the guide means controlling their tilting from this position.
• the invention advantageously provides for constituting the load-carrying tractor means, in each conveyor, by two coupled cables, between which the assembly points of the pendulum arms are located, the coupling between the two cables being ensured, at each pendulum arm, by the assembly device of the latter, which engages on one and the other of the cables by two clamps located at the ends of the articulation axis.
• the arms are suspended between the respective guide wheels of the two cables.
• the receiving members of the arms in the folded position may be constituted by these assembly devices, or by different members but also rigidly connected to the two cables between them.

• each box with its sledge is taken from a conveyor on the ground located upstream, illustrated in FIG. 8 by two roller tables 71 and 72.
• the sledge with the box it carries is placed on another conveyor on the ground, or downstream conveyor, which is generally also of the roller table type.
• each cable 60 is driven in translation on itself to describe a loop which closes in a vertical plane at each end of the installation, on the one hand at the loading station 7, on the other hand at the unloading station 8.
• the motor means which drive the cables have not been shown . They can be of any type known per se. They are preferably produced as described in the aforementioned parallel patent application, in order to ensure the synchronization of the two conveyors in speed, while also ensuring, in position, a precise correspondence between two homologous arms 4L and 4R, which must be find aligned on the same transverse perpendicular to the circuit plane.
• the cables 60 are constituted in a conventional manner, by a plurality of strands wound in a helical twist around a central core, each strand itself being advantageously formed of several strands of metal wires assembled in a spin.
• the cables Before starting up the installation in operation normal for the transport of loads, the cables require to be subjected to a progressive tensioning procedure during which they lengthen. Once this procedure is completed, they remain taut almost without further elongation.
• the circuit imposed on the pendulum arms is defined by guide wheels 63, distributed along the installation.
• Such guide wheels are located in particular, sometimes above, sometimes below the cable path, where unevenness must be imposed, as is the case when the boxes must be immersed in treatment baths, this which is illustrated by a station 2 in FIG. 1.
• the guide wheels can be reduced to simple rollers or rollers 65 of small dimensions. Between two guide wheels, or groups of guide wheels, the loads are exclusively carried by the cables.
• FIG. 2 thus illustrates a box and its sledge entirely carried by the cable 60, between two guide wheels over which it passes, by means of two successive pendulums 4.

• FIG. 1 also shows that the arms 4 returning empty are folded over the cable, and it schematically illustrates a ramp 66 which retains their fall when they rock around the return wheel 62 of the loading station.
• FIG. 1 The schematic representation of Figures 1 and 2 shows only one cable for each conveyor.
• the two conveyors are of the two-cable type, that is to say that they comprise two parallel cables to which the different pendulum arms are assembled. This makes it possible to better carry the weight of the loads by distributing the forces, and consequently to take full advantage of the advantages that the structure of the cables entails, when, as here, they constitute both loads for tractors and carriers.

Sufficient spacing is provided between the wheels 63a and 63b opposite, so as to allow the passage of the pendulum arms 4, freely hanging between them, without shock or friction.

• each arm 4 there is provided at the end of each arm 4, a roller 41, whose essential role is to cooperate with the ramp 66 when the arm rotates around the idler wheel 62 of the loading station. It can be seen that this roller 41 is placed laterally on the hook 42, overhanging the latter and on the inner side with respect to the conveyor line, and that the hook 42 itself is offset from the inner side with respect to the rest of the straight bar constituting most of the pendulum arm.
• the use of dual-cable conveyors as described here lends itself particularly well to an installation using so-called narrow sleds.
• the arms 4 bypass the outside of the body transported to join the crankpins of the sledge, which are arranged recessed, under the body.

• FIG. 7 which shows successive arms being in different positions at the level of the loading station, has the advantage of clearly showing the constitution of the front and rear pendulum of load suspension by four suspension arms independent and the joint behavior of the two conveyors, 6R on the right and 6L on the left. It also represents the two ramps 66R and 66L which are respectively associated with each of the two conveyors. Each one is shaped so as not only to avoid a sudden fall of the arms, but in addition so as to keep them in a tilted back position long enough to pass them without difficulty away from the elements of the roller conveyor until bringing them in position of attachment in front of the crankpins of a sledge waiting on approach to the station.

It also shows that this frame supports rollers 73 which are sufficient to guide the cables when, in their return journey from the unloading station to the loading station (arrow B), they no longer carry the sleds 3 with the vehicle bodies 5, but only pendulum arms 4.
• the operation of hooking the sleds to the loading station is better illustrated in FIGS. 8, with reference to the pendulums 4 as comprising the two symmetrical lateral arms.

• the pendulums rotate in opposite directions around their axes of articulation on the cables, while they make a total turn in space.
• the rotation of each arm in space is substantially a quarter of a turn, in the levogyro direction, to pass from the position hanging vertically out of the unloading station to the folded position on the cables.
• it is three quarters of a turn, in the dextrorotatory direction, to pass from the horizontal orientation folded along the cables to the vertical orientation at the loading station.
• the path of the cables requires the heads of the pendulum arms to descend to a level low enough for the hooks to have their opening at the level of the cooperating crankpin of a sledge which still rests (at the loading) or already resting (at the unloading station) on a roller conveyor table on the ground.
• the effects of the deflection wheels and those of the cable guide rollers which follow or precede them on the circuit are combined with those of the retaining ramp on the one hand, and of the support members on the other hand, to control the rotation of the arms so as to facilitate the cooperating operation of the hooks with the corresponding crankpins, but also to control their movements in a flexible and safe manner.
