Then all these covers 33 are placed in storage device 55 via the arm 52 that prehension device 60 carries cover 33, such as scheme Illustrate in 11.For this purpose, make cover 33 in this total of three, this be only an embodiment with respect to they Position on one groove 3 rotates 90 °, and lateral edges 36 are therefore less horizontal, and passes through storage device 55 by arm 52 The forward part opened be placed in this storage device.

Cover 33 is placed between two pillars 71,73 in storage device 55, shield 72 in the open position so that Being capable of introduced cover 33 (Figure 11).

Then shield 72 is made to move to its closed position so that cover 33 is maintained between pillar 71,73 and shield 72 (Figure 12).Then prehension device 60 and cover 33 disconnection, the risk falling without them can be made.

Once removing cover 33 from groove 3, pond is looked after machine 10 and just can be intervened groove 3 to execute multiple operations, especially Ground but not exclusively be replace anode.During these interventions, cover 33 is maintained in retracted position, and therefore without prejudice to this A little interventions.In more general terms, arm 52 and whole system 50 are oriented to these interventions of without prejudice to.Specifically, can be with lift system 50 (by means of telescopic support 51 in described embodiments), and after a while when will need again using this system execute It will be made to reduce during other operations.

Arm 52 necessarily maintains cover 33 can be used to execute other operations, mostly by way of other works Tool.Therefore, first, arm 52 is made to get loose from prehension device 60 in storage device 56 by being placed on prehension device 60, typical case Ground is on corresponding component 64.

Then the first coupling device 61 by being arranged at the first end 53 of arm 52 is present in storage device with being arranged on One of 56 instruments are different from the cooperation between the second coupling device 62 in prehension device 60, and arm 52 is connected to This instrument.Then arm 52 can be associated with the operation of groove 3 but unlike that manipulating the operation of cover 33 using the execution of this instrument.

In the embodiment that figure 13 illustrates, this instrument is burnisher 63, and this burnisher is used to clean groove 3 At least one region, as shown in Figure 14.

Specifically, after having substituted for an anode, and appropriate location cover 33 being put back on groove 3 it Front it is necessary to cleaning guide groove 35, along whole length unlapped when cover 33 is removed, thus remove being possible in sun The fragment falling during the replacement operation of the pole 40 i.e. hard bath chip bathed and crush.In order to clean guide groove 35, cleaner Tool 63 typically these fragments can be placed on inside pond 20.Arm 52 preferably should be designed that lifter positive in right part Positive lifter 47 cleans below without turning back with left part.

Once completing clean operation it is possible to be put back into burnisher 63 in storage device 56, it is in corresponding element On 64, and and then arm 52 can be made to disconnect with burnisher 63.

Then arm 52 can be connected to another instrument being present in storage device 56 to execute another operation.

As illustrated in Figure 15, by being arranged on the first coupling device 61 at the first end 53 of arm 52 and setting previously Cooperate between the second coupling device 62 that arm 52 has been placed in the prehension device 60 in temporary memory device 56, arm 52 is permissible Fetch this prehension device 60.

Then arm 52 equipped with prehension device 60 can fetch being previously placed in storage device 55 in this way Individual or multiple covers 33.This operation does not need the equipment of an accurate location that can detect cover 33, because since they are placed In storage device 55 after they be always held at arm 52 identical reference position in.Which save the time and enhance Reliability.

Once gripping member 59 is suitably associated with cover 33, the shield 72 of storage device 55 can be made to move to it and to open Position is to allow to remove cover 33 from storage device 55.

Then, as illustrated in Figure 16, arm 52 is moved to it is put back to the cover 33 that it keeps on groove 3. To enable rightly reorientating cover 33, system 50 can include a testing equipment, and this testing equipment can detect One with groove 3, element that the position that must be repositioned onto cover 33 by arm 52 is adjacent.This adjacent element can be such as It is a neighbouring cover 33 in place on groove 3 or a transverse end being in groove 3 in cover to be relocated On cover in the case of be groove 3 an end wall.

Cover 33 is inserted in previously cleaned guide groove 35 arm 52, and places them in superstructure 30 Edge 31 on.

To the degree storing cover 33 on Z in an overlapping manner, wherein their lateral edges 36 are less horizontal , in cover 33 before groove 3 removes, it is understood that there may be any space between two neighbouring covers 33 is corrected by gravity. Therefore, the overall dimension of all covers 33 in return-enclosure 3 to be placed removes from groove 3 along Y less than here group cover 33 Up till now group cover 33 general size.In other words, can be used on groove 3 places the position of cover 33 more than along this group cover 33 The yardstick of Y.Greatly facilitate the placement of the cover 33 on groove.

Just described process can automatically be implemented, have been sent from being positioned at the pond above groove 3 and looking after machine 10 System 50 independent operation after a cycle enabled instruction.

Alternatively, especially for being adjusted, manually operate and can be considered, acted on by operator and be present in pond The indoor control member that controls looking after machine 10 executes operation.

Therefore, the system according to the present invention makes it possible in very crowded cell environment and with required standard Exactness manipulates cover and executes other operations (cleaning etc.).

Due to its modularity, this system can also make be substantially reduced cycle time, e.g., less than 100 seconds (the taking, cover of cover Cleaning and put back to).

Because this system is compact, it can execute specific operation such as background task, does not cause and pond to them Look after the degree of the risk of an element collision of machine.Outstanding for the tool changing situation between prehension device and burnisher It so looks after machine 10 interference tank 3 so that the curst of bath ruptures, removes the anode exhausting or replace new anode in pond Described tool changing can be completed simultaneously.

In addition to financial influence, reduce cycle time be favourable in terms of safety and environment because decreasing from groove Remove the time of cover.

Certainly, the invention is not restricted to foregoing example embodiment, but include all technically equivalent ones of foregoing approach With modification with and combinations thereof.
