Definitions
- the present invention relates to the design and realization of a chemical treatment installation by soaking parts contained in cages, or other containers, such treatment involving immersion in a tank containing a bath treatment. It applies in particular to installations in which the chemical treatment itself is a treatment of manganese phosphating used on parts of motor vehicles. It also applies to any installation similar, knowing that in essence chemical treatments at soaked use relatively polluting baths.
- the parts to be treated are arranged in containers, or cages, from other manufacturing units and which are then returned to the chain.
- these containers To guarantee the cleanliness of these containers, they must be completely immersed in the various tanks, in particular in the tank phosphating to avoid a phosphating bath interface / atmosphere and in degreasing or pickling tanks for thoroughly clean the entire container.
- the containers are placed bottom of tanks. We can therefore avoid only the manipulators who are used to move containers from one tank to another either in contact with the different baths and undergo alterations. And, except for the drying steps, you cannot more avoid that the manipulator leaving a bath with his load entrains liquid which may drip onto the equipment neighbors, hence additional difficulties in maintaining the purity of the various baths and for the safety of the workers.
- the present invention aims to propose an installation for chemical treatment by immersion in a tank containing a chemical treatment bath, for parts constituting charges contained in containers or cages which, in other tanks, are also subjected to a treatment prior preparation and subsequent finishing treatment, which is much more compact in terms of its size, which offers flexibility of use allowing adapt to very different capacities, including maintenance be easy. More generally, it aims to resolve the different difficulties that the industrialist faces in this field, including those that have been highlighted above.
- the installation according to the invention is notably remarkable in that the tanks of the various treatment stations are arranged on two parallel lines separated by an aisle allowing access to the tanks, a first line comprising a loading and unloading device at one of its ends and preparation tanks, and a second line with two chemical treatment tanks which are used in alternation and finishing tanks, in that a longitudinal transfer is provided in each line, to take turn each load in a tank and place it in a other, and in that it includes transverse transfer means ensuring the connection between the two lines, in forward direction and in direction return.
- the loading device and unloading which is unique because at only one end of the first line, has several load receiving cells, to each receive a charge at the entrance or exit of installation.
- the invention is embodied in various embodiments of installation, which may vary depending on whether the application envisaged leads to favor or not the possibility of doing intervene workers on a stationary chemical treatment tank while the other is in operation as well as the rest of the different equipment of the installation.
- the circulation of cages containing the charges to be treated can advantageously be organized so as never to pass a cage emerging from a polluting bath over a keep clean and circumscribed around the treatment tanks chemical areas where they may drop liquid drops or other soiling. This avoids having to equip the tanks of the so-called clean areas with covers and sealing devices for the passage of cages.
- the two chemical treatment tanks are arranged each at one end of the second line and tanks different finishing associated with them, respectively between the corresponding tank and a central zone of the installation between the two lines. It is then advantageously in this middle zone that the means for transferring the loads are arranged from one line to the other.
- a single manipulator can be used for this purpose, from when it includes the means giving it the degrees of freedom necessary for it to be operative as well in the sense go for bring the charges to a chemical treatment tank (phosphating for example), only in the return direction to take them back at the outlet of the last corresponding tank (finishing tank).
- a chemical treatment tank phosphating for example
- finishing tank finishing tank
- the invention comprising three rinsing tanks used in the context of the preparation treatment, one of these tanks is placed in each line while the third is placed between the two lines, in the central aisle, the three tanks being aligned in a transverse direction so as to make an H-shaped arrangement of all the tanks.
- es transverse transfer means include two manipulators distinct, this solution being particularly preferred when the two chemical treatment tanks used alternately are grouped side by side on the second line.
- Said means then advantageously comprise, by placing themselves particularly in the context of a phosphating installation of metal parts, a first link transfer manipulator arranged at a tank of the final treatment station preparation and moving a cage from the first line to the second line and a second transfer manipulator link transfer arranged at a tank of the final station of the finishing treatment and passing a cage from the second line to the first line.
- the design according to the invention advantageously allows to use tanks with symmetry with respect to their axis or at their center so that each tank can be placed in one line or the other; just turn it over 180 degrees.
- On the side of the tank which is adjacent to the aisle central we have everything related to power circuits, especially the heating resistors, so we use a single power supply line.
- the treatment tanks chemical for example phosphating
- the aisle separating the two lines allows to obtain an intermediate position of the transfer means transverse in which the two longitudinal manipulators can move on all of their respective lines.
- each loading / unloading cell can receive a carriage with its load and this carriage is immobilized in the cell until the load returns, i.e. all of the parts contained in the same cage.
- This provision ensures that loads do not remain during processing, since the carriage remains a prisoner until the return of his charge.
- the work of operators is minimized since their only actions consist of bringing the carts in or out of the cells, loads then being moved by the manipulators. In particular, it is no longer necessary to push or pull batteries baskets, which simplifies the carts, which can consist of a simple rolling table.
- the installation according to the invention is produced in the form of pre-assembled modules comprising the loading / unloading device or tanks with their support and their vapor extraction device and at least one part of the manipulator support.
- This modular structure which is for example consisting of six or seven modules which are delivered pre-assembled and assembled at the place of use, allows minimize on-site operations.
- the load consists of a U-shaped cage containing the parts to be treated and provision is made in each cell for loading / unloading, an intermediate support which provided with a upper horizontal wall forming a cover and on which the cage remains attached for the duration of the treatment, the support intermediary being grasped by the manipulators and placed on each tank in such a way that the cage is suspended in the tank and fully immersed in the treatment bath.
- the intermediate support provides immersion total of the cage while protecting, thanks to its cover, the manipulator of any contact with the baths.
- the supports receiving the intermediate support are out of the bath, allowing easily perform their initial adjustment for alignment horizontal. Finally, these supports are closer to the manipulator so well that there is no problem centering the latter.
- the cage has horizontal rods at the top which are perpendicular to the direction of translation of the manipulators longitudinal and which cooperate with hooks arranged at the lower part of the intermediate support, hooking or stalling of the cage on the intermediate support being obtained, in each cell, by a small horizontal displacement followed by a longitudinal manipulator lifting movement of the first line.
- the intermediate support includes measuring devices and / or a data storage device in which the monitoring of the treatment is recorded.
- the installation includes cascade rinsing tanks arranged Adjacent in a line, on the side of each tank of rinsing, a first siphon wall parallel to the line, which connects to a complete partition perpendicular to the line to form, with the side wall and the upstream partition of the tank, a water inlet area and a second siphon partition perpendicular to the line which connects to a complete partition parallel to the line to form with the side wall and the downstream wall of the tank, a water drainage area, the upstream and downstream walls comprising, in the water inlet and outlet areas, a upper notch, the lower part of which is substantially at level of the rinsing bath.
- the rinse water is supplied so on the side of the tanks and the siphoid partitions allow circulate the rinse water all around the load before it is evacuated.
- the upper part of the siphoid walls is crenellated in such a way that the elements floating around in the bath rinsing also circulate in the tank passing over the siphoid partitions.
- the water arrival and discharge zones are arranged on the outer sides of the line. Of this way, these areas are accessible without having to enter the internal aisle separating the two lines, outside the curtains generally provided side protection.
- the area between the two arrival areas and drain is a measurement and sampling area of the bath. This area is in direct communication with the bath surrounding the load, and we can therefore carry out measurements of the load processing conditions.
- the water drainage area constitutes an area of bath level control. Level measurement in this area advantageously controls the water supply to the first tank.
- the lower part of the first siphon wall is curved in direction of the downstream wall of the tank.
- the resulting strangulation adjusts the flushing of the rinsing water, i.e. the proportion of rinsing water which passes under the siphon tank and that passing over.
- Figure 1 shows schematically in view of above, a first embodiment of a compliant installation to the present invention which is intended for a treatment of manganese phosphating of parts from the automotive industry, for example gearbox gears.
- the different treatment tanks are arranged with contiguously on two parallel lines 1 and 2 which are separate by a central aisle 3.
- the first line 1 includes a device 4 loading and unloading of loads which comprises several adjacent cells 20 capable of receiving a carriage carrying containers containing the parts to be treated.
- this loading and unloading device 4 are two tanks cooling 5 and 6, then a drying tank 10, a first alkaline rinsing tank 7 and a degreasing tank 8.
- the second line 2 has at each of its ends a tank of phosphating 9 and 11, and to each of the two phosphating, there is associated an adjacent refining tank 12 and 13.
- a drying tank 17 similar to drying tank 10 in line 1.
- the two drying 10 and 17 are aligned in one direction perpendicular to the two lines.
- a third rinse tank alkaline 18 is placed adjacent to the drying station 17 at the end of which are the refining tank 13 and the phosphating 11.
- An alkaline second rinse tank 19 is arranged in aisle 3, in transverse alignment with the tanks first rinse 7 and third alkaline rinse 18, these three tanks being adjacent to each other. We therefore obtain a disposition in "H" of all the components of the installation.
- the displacement of the loads in the first line 1 is realized by means of a first longitudinal manipulator with two axes able to carry out translational movements parallel to the first line 1 and lowering or lifting movements of the charge.
- a second longitudinal manipulator with two axes is provided for the displacement of the loads in the second line 2.
- the various constituent elements of the installation are assembled according to pre-assembled modules, which are assembled in the factory and which are assembled together on the site of job.
- Each of these modules includes one or more tanks, or the loading / unloading device with the tank support and vapor extraction device (not shown), as well as part of the support on which the manipulators.

- a third module includes the three alkaline rinsing tanks 7, 18 and 19 with the entire transverse link manipulator as well as part of the support of the transverse manipulator of line 1 and part of the support of the longitudinal manipulator of line 2.
- a fourth module includes the degreasing tanks 8 as well as part of the support of the longitudinal manipulator of line 1
- a fifth module includes phosphating 9 and refining tanks 12
- a sixth module includes the three acid rinse tanks 14 to 16
- the seventh module includes the phosphating tank 11 with its associated refining tank 13.
- Figure 2 shows a variant of the installation of the figure 1. It contains a certain number of constituent elements of the installation of Figure 1 with the difference that the two tanks of drying 21 and 22 are arranged after the rinsing tanks acid 14 to 16 with which they constitute a module. Through elsewhere, the two cooling tanks 23 and 24 are placed at the location of the drying tanks 10 and 17 of the installation of the Figure 1. This embodiment has only six modules at place of seven in the installation of figure 1 a new module grouping together the three alkaline rinsing tanks and the two cooling 23 and 24 and the two drying tanks 21 and 22 being grouped in the acid rinse module 14 to 16.
- FIG. 3 represents another embodiment of the invention. It contains the loading device and unloading 4 with its cells 20, following which are successively arranged the degreasing tank 8 comprising two cells, the alkaline first rinse tank 7, the second alkaline rinse 19, and the third alkaline rinse tank 18, in which the last stage of the processing of preparation.
- This tank 18, which is therefore the final tank for the treatment preparation, extends over the entire width of the installation, i.e. on lines 1 and 2 and on aisle 3.
- a first link transfer manipulator which performs the passage from the first line 1 to the second line 2, is arranged at this final tank 18. It is constituted by a carriage transfer 25 which moves longitudinally in the tank 18 and which receives charges which are deposited there by the longitudinal transfer of the first line 1 and which are taken up by the longitudinal transfer manipulator of the second line 2. It it is therefore a simple manipulator with a displacement axis.
- the second line 2 we find, starting from the tank final preparation 18, a refining tank 12, the first tank of phosphating 9 comprising three cells, the second tank of phosphating 11, the first acid rinse tank 14, the second acid rinse 15, the third acid rinse tank 16 and the two drying tanks 17 and 10.
- the cooling tank 5 is arranged in the aisle 3, at the opposite end of the device from the loading and unloading 4, just after the final preparation tank 18. From on either side of this cooling tank 5, provision is made, in each of lines 1 and 2, a maintenance station 26 and 27 of the longitudinal line transfer manipulator.
- a second transfer manipulator is provided.
- link 29 which is also constituted by a transfer carriage and which carries out the return from the second line 2 to the first line 1.
- the two link manipulators consist of a single manipulator with three axes of displacement 63 which, as described elsewhere, goes from the first line 1 to the second line 2 at the level of the alkaline rinsing tanks 7, 19 and 18 and the passage return from the second line 2 to the first line 1 at the level of drying tanks 17 and 10 in the case of FIG. 1 and at the level cooling tanks 23 and 24 in the case of FIG. 2.
- the embodiment of Figure 3 has four modules, in addition to the loading and unloading device 4.
- the first module includes degreasing cells 8, first alkaline rinse 7 and second alkaline rinse 19.
- the second module groups the refining cell 12 and the phosphating constituting the first phosphating tank 9.
- the third module includes the second phosphating tank at three cells 11.
- the fourth module contains the tanks first, second and third acid rinses 14 to 16 and the station drying system comprising tanks 17 and 10.
- the fourth module consists of the alkaline third rinse tank 18 and the cooling station 5.
- Each of the cells 20 of the loading device and / or unloading 4 can receive a trolley on which a container constituting a basket in which the pieces are placed of metal to be treated.
- the containers intended to receive the parts to be treated are in fact constituted by a kind of "U" shaped cage with a bottom and two walls lateral verticals. This basket structure provides very good circulation of the treatment baths around the rooms to be treat.
- Such a cage is shown in Figure 3. It has a bottom 31 and two opposite vertical side walls 32. When a cage is in position in a cell 20, the walls lateral 32 are parallel to the direction of the line of the tanks. Each upper wall has two rods 33 which are perpendicular to the line of tanks and which cooperate with hooks arranged at the bottom of an intermediate support suitable for being gripped by a transverse manipulator or the manipulator link.
- Figure 4 shows in section such a cage 30 above from which there is an intermediate support 34, which can be grabbed and transported by a manipulator 35.
- the support intermediate 34 which is shown in cross section on the Figure 5, has hooks 36 which are arranged in a plane parallel to the tank lines at the bottom of the support 34. These hooks 36 are fixed on transverse horizontal bars 37 arranged at the upper part of the intermediate support 34. In below these bars 37 is a plate 38 forming cover, which is inclined relative to the horizontal as can be see in figure 5, and which, as we can see in figure 4, is folded along a transverse axis, so as to have the shape of a Very open "V" directed upwards. Bars 37 can be gripped by the manipulator 35 by means of displacement pliers horizontal.
- FIG. 6 shows, in top view, the three tanks acid rinse 14, 15 and 16, which are arranged one behind the other in the installation line.
- a load constituted by an intermediate support 34 and a cage 30 The whole of this cage and its support intermediate is suspended above the bath, the cage 30 being fully submerged and hung on the intermediate support 34; the ends of the bars 37 of the intermediate support 34 rest on supports 42, arranged on the edge of the tank, which have in section the shape of a "V".
- These three acid rinsing tanks 14 to 16 are arranged and arranged in such a way that the water arriving upstream through a line 28 flows successively in the third tank rinse 16, the second rinse tank 15 and the first tank rinse 14, then to reach a drainage area from where the residual water is recovered, for example by means of a pump, and sent to the phosphating tanks. This is possible because we are in line 2, in a processing set at acidic environment.
- the different tanks are separated from each other by total partitions, that is to say partitions which are connected to the bottom of the tank, but these partition walls 44 and 45 have, on the left side, a notch allowing the cascading from one tank to another.
- the cascade circulation of the bath water is produced by means of siphoid partitions which are arranged according to a special arrangement.
- a first partition siphoid 46 is arranged in the left part of the tank, parallel to the axis 50 of the tank line 2.
- This partition siphon is connected on the one hand to the upstream partition 47 of all the tanks, and on the other hand, to a total partition 48 which is perpendicular to axis 50 and connects to the left side wall 49 of all the tanks.
- each tank In the downstream part of each tank is finds a siphon partition 51 which is perpendicular to the axis 50 and which is connected to the side wall 49 on the one hand and, on the other hand, to a total wall 52 which itself connects to the downstream wall of the tank, namely the partition wall 44 or 45 or the wall 53 separating the first rinsing tank from the drainage area.
- each of the siphoid partitions 46 and 51 have at its end upper passages, in the form of crenellations, the bottom of which is substantially at the level of the bath of the tank.
- the walls 46 and 48 delimit a water inlet zone and the walls 51 and 52 delimit a water drainage area.
- a zone 54 is in direct and complete relation with the rest of the tank. This zone is used to make measurements to determine the conditions of operation of each of the rinsing tanks 14 to 16.
- Figure 10 is a partial section showing a wall siphoid 51, parallel to the line of the tanks, and a wall of separation, for example, the wall 53.
- this section which is a section in a plane parallel to the second line 2 in the left part of the tanks, the opening 56 arranged in the wall total 53 and the slot 65 which is arranged in the upper part of the siphon partition 51.
- the bottom of the opening 56 corresponds substantially at level 57 of the bath in the tank when the latter is empty and the bottom of the slots 55 corresponds substantially to the level 58 of the tank when a load is introduced.
- the siphoid wall 51 is curved in its lower part, in the direction of the wall 53, so as to create a constriction which determines the "hunting" evacuation of water from the tank when a load is introduced in the latter.
- the depth and the shape of this curvature 59 are determined to obtain an evacuation of bath water 90% below the siphon partition 51 and 10% above by slot 55.
- a tube 60 arranged at the bottom of each tank transversely and centrally, which is used to stir the bath by sending air bubbles. This allows a good mixing of the bath under loads and in the water intake and drainage areas, except for the zone 34 in which there is no disturbance and we can take measurements as well as bath samples.
- Figure 11 is a cross-sectional view through the refining and degreasing tanks 8. We can see the loads shown in broken lines and based on supports in "V" 42 as well as the heating resistors 29. We see also in this figure the manipulator 61 of line n ° 1 and the manipulator 62 of line n ° 2 in the raised position so as to be able to circulate above all the tanks.
- Figure 12 is also a cross section through through the alkaline rinsing tanks 7, 18 and 19.
- the transverse link manipulator 63 is also in the high position so that it can circulate transversely on the three rinsing tanks 7, 18 and 19.
- Trolleys consisting of simple tables on casters, receive charges and they are brought into one of the cells 20 loading / unloading device 4. Power can be done manually or by automatic systems, by example those who use so-called wire-guided carts, which are move on a predefined circuit.
- the first operation consists in associating a support intermediate 34 which is assigned to each of the cells 20 to each of charges constituted by a cage 30.
- the manipulator 61 comes to grip the intermediate piece 34 which rested on supports 39, then it performs a lifting movement to release the intermediate support 34 from the supports 39.
- the manipulator longitudinal of line 1 is brought into the cell considered in a position such that its hooks 36 are slightly offset by relative to the attachment rods 33.
- a movement is then carried out down so that the hooks 36 are located below the level of the hanging rods 33.
- a slight translational movement in the axis of the tank line so that the hooks are located just below the hanging rods, and we end with a lifting movement so that the rods 33 are gripped by the hooks 36.
- the manipulator 61 brings the load successively in the three degreasing tanks 8, then in the first alkaline rinsing tank 7. Each time, the manipulator 61 emerges from the intermediate support 34 and poses this on the supports in V 42. During the treatment of a load, the manipulator 61 can handle other loads for the pass through different vats.
- the transverse link manipulator 63 then enters the load in the tank 7 to pass it successively in the second rinsing tank 19 and the third rinsing tank 18.
- This link manipulator 63 when it is not not used, positioned above the second rinsing tank 19 so as to allow free passage for the other two transverse manipulators 61 and 62, these being able to evolve on their whole line.
- the load is then taken by the longitudinal manipulator 62 of the second line, transported from the rinsing tank 18 to a refining tank, corresponding to the phosphating tank which is in operation, for example the ripening tank 12.
- the charge is then brought into the phosphating tank 9, then into the three acid rinse tanks 14, 15 and 16.
- the load is brought to a drying station 10 or 17 and then to the cooling 6 or 5.
- the treatment is finished, the charge returns to his cell, where his carrying cart awaits him, who can then bring it back to the manufacturing line.
- the installation processes simultaneously multiple loads, which are handled by one of three manipulators 61 to 63.
- the manipulator 63 also has a position intermediate, i.e. above the second rinsing tank alkaline 19, where it allows the free movement of the other two transverse manipulators 61 and 62 over the entire line 1 or 2.
- the installation can operate with a active phosphating and a phosphating tank in progress cleaning, which does not interrupt the operation of the installation for tank cleaning operations. This cleaning is further facilitated by the fact that each of the phosphating 9 and 11 is accessible on three of its sides.
- the refining tank associated with the other tank being cleaned is advantageous to use as a "premix" tank, that is to say as a tank in which the bath intended for the tank is prepared refining in operation.
- the cleaning operation of a phosphating tank is carried out in complete safety because a partition is interposed between it and its refining tank so as to prevent any access to the phosphating tank being cleaned.
- all the stations preparation processing are arranged in the first line 1 which is therefore a "clean" line, that is to say that the charges circulate in the line without danger of falling droplets including a chemical when passed over it other charges placed in a processing station.
- Only the alkaline third rinse tank 18 also extends over aisle 3 and the second line 2.
- the second line 2 includes all the positions of the finishing treatment, with the exception of cooling station 5 which is located in aisle 3, and the chemical treatment tanks, ripening 12 and phosphating 9 and 11.
- This second line can be seen as a "dirty" line due to the fact that charges containing a chemical can circulate above others loads being processed.
- the different tanks are arranged in the order of the stages of treatment, starting from the loading and unloading 4, in the first line 1, and in the opposite direction, starting from the third alkaline rinse tank 18, in the second line 2.
- each load travels the entire line 2 passing through one of the tanks of phosphating 9 or 11 and returns to the dry state, therefore without risk of falling droplets, passing over all tanks to reach the level of the second link manipulator 29 which la passes into the cooling chamber 5, then into the first line 1.
- the load is then taken up by the manipulator cross of line 1 and transferred to its cell of the device loading and reloading 4.
- the level in the different tanks is regulated by means of a device for measuring level located in zone 43 which is not turbulent and which acts on the flow rate of the clear water supply device 28.
- a device for measuring level located in zone 43 which is not turbulent and which acts on the flow rate of the clear water supply device 28.
- the passage of clear water supply to the third rinsing tank 16 takes place simply below the siphon partition 46.
- the level rises as shown in Figure 10 and the passage of the first bath of rinsing in tank 15 is then 90% below the siphon partition 46 and 10% above by the slots 55; in especially the supernatants are then removed from the area water supply to tank 16.
- the water sent to the tank 16 circulates in the latter, being stirred by the air bubbles sent by the pipe 60 and the bath comes out in the area 54 to pass, still 90% below the siphon partition 51, 10 % of the bath passing over the slots with the supernatants.
- the same phenomenon occurs for tanks 15 and 14, which ensures complete circulation of the bath, and the contaminated water located in zone 43 is evacuated, for example by a pump, and sent to a phosphating tank. This makes it possible to limit the water consumption of the installation as much as possible, to arrive at a very reduced consumption which is for example less than two liters of water per m 2 of surface of the treated part.
- the cages 30 are, each time, completely immersed in the baths, which avoids any interface between a bath and the atmosphere that could create damage to the cage. Through elsewhere, it is completely cleaned in the rinsing tanks and degreasing. It can therefore be reused and returned to the manufacturing line.
- the cover 38 provides total protection of manipulators. In addition, it makes it possible to collect and evacuate to the outside of the tanks the condensates which can form above of these.
- the intermediate supports 34 are fitted with measuring devices, such as temperature, as well as data logging devices which make it possible to make a recording of the treatment monitoring complete, with particular indication of temperatures and times of each treatment.
- measuring devices such as temperature
- data logging devices which make it possible to make a recording of the treatment monitoring complete, with particular indication of temperatures and times of each treatment.
- the corresponding data can be picked up and sent on an information carrier accompanying the parts in the rest of the manufacturing stations.
- the invention makes it possible to obtain an installation extremely compact compared to online installations current.
- Using two chemical treatment tanks allows to obtain a great flexibility in the capacity and the rate of operation of the installation. Indeed, when one of the two phosphating tanks 9 or 11 is considered to be soiled and requires cleaning, we use the second tank, which allows not to interrupt the operation of the installation which is only stopped when the second tank is also soiled in order to clean the two tanks.
- the two tanks processing are arranged at one end of the second line and can be isolated, the tanks can be maintained without stopping the operation of the installation.
- the arrangement of the different tanks in two lines with a central aisle makes it easy to carry out operations maintenance and monitoring kits.
- the use of the intermediate support provides containers which have not deteriorated during processing and which can therefore be reused. They can, in particular, be handed over in service in the production line.
- the two tanks of cooling are arranged in the loading device and / or unloading in a variant according to which provision is made two additional loading / unloading cells of so as to obtain three cells accessible to the support trolleys charges.
- the other cells including the two with a cooling tank, are closed and contain only supports which can receive the intermediate supports.
- the fact of providing three loading / unloading cells allows group the movements of the manipulator, which leaves more free time for the operator who must store empty carts corresponding to closed cells in the vicinity of the installation.
- the hooks of the support intermediate are directed in a plane perpendicular to the axis of two lines and that the hooks arranged on one side of the support, by example the hooks arranged on the outside of the line, are offset from the other two hooks, an offset corresponding being provided for the attachment rods of the cage.
- the first attachment rods of the cage which are made in the form of rings, pass by the hooks of the intermediate support and are placed in the two other hooks.
- the rods are in their corresponding hooks a little above the bottom of the hooks, so that taking the cage is obtained by a single lifting movement of the manipulator. Due to the axial symmetry of the arrangement of their rods, the cages can be inserted from any side, the rods always positioned for correct positioning in the cell.
