- these cylinders are single acting , the lifting of the pressure frame 34 in the open position, being controlled by return cylinders 30 '.
- the lower crew 1 ' comprises a plurality of planing rollers 11' bearing on support rollers 12 ', said rollers being rotatably mounted about their parallel axes on a support frame 10' which builds on the bed frame 32.
- the upper planing rollers 1 1 and lower 1 1 ' are offset longitudinally so as to provide a corrugated path of the band, their nesting can be adjusted by the cylinders 34'.
- planing machines for sheets or thick strips have, depending on the case, from 7 to 1 rolls of planing.
- the upper crew can carry five rollers 11 and the lower crew six rolls 11 '.
- Such machines applied to bands and plates of large width and thickness can reach a mass of more than 300 tons for a height greater than 10 meters, a planing crew may have, in itself a mass of several tens of tons.
- rollers are subjected to high surface pressure stresses and abrasion phenomena that require their repair, for example machining by grinding their active surfaces, in a workshop. of maintenance.

- the upper planing member 1 on the pressure frame 34 by means of the removable fastening devices 2 shown in detail in Figures 5 and 6.
- the frame 10 of the upper cassette 1 is applied to a lower face of the pressure frame 34 and held on each side, for example by means of four fastening devices 2, as shown diagrammatically in FIG. FIGS. 5, 6, 7, each fixing device
- FIG. 2 comprises a hook 21 pivotally mounted about a horizontal axis 21 1 between a spaced apart positioning position of the cassette 10, shown in FIG. 5 and a locking position shown in FIG. 6, after engagement of the end 210 of the hook 21 under a locking pin 101 formed on an ear-shaped bearing portion 102 extending outwardly projecting from the lateral side 103 of the chassis 10 of the upper crew 1.
- the pivoting of the hook 21 is controlled by an articulated mechanism 22 actuated by a jack 23 bearing, on one side, on the lateral side 340 of the pressure frame 34, about an articulation axis 231 and, of the another side, on a crank 232 set in rotation on a shaft 233 which actuates the mechanism 22 of the hook 21.
- the hooking means 2 are actuated in pairs, the same jack 23 being placed between two hooks 21a, 21b actuated simultaneously by a central crank 232.
- the articulated mechanism 22 comprises, for each hook, a crank 221 secured in rotation by the shaft 233 with the central crank 232 and whose end is connected by a connecting rod 222 to a first arm of a cranked lever 223 having a second articulated arm around a fixed axis 224 and whose central portion is articulated on the hook 21 around a central axis 213.
- crank 221 and the bent lever 223 each form a yoke flanking the hook 21 which extends vertically between its lower end 210 forming a latch and an upper end hinged about the axis 21 1 which is mounted on a slide 212 vertically guided by lights provided on the two wings of a clevis 341 for supporting the mechanism 21, 22, fixed on the lateral side 340 of the pressure frame 34.
- the hook 21 is hinged about a horizontal axis 213 on the central part of the bent lever 223 and this axis 213 is arranged so that the upper arm of the bent lever 223 is parallel to the crank 221 and the assembly forms a deformable parallelogram with the connecting rod 222.
- the rotation of the crank 232 controlled by the jack 23 and transmitted to the crank 221 by the shaft 233 determines a rotation of the same angle of the arm 223 of the bent lever which bears on the fixed axis 224, with a displacement vertical axis of the central axis 213 and the slide 212 bearing the upper pivot axis 21 1 of the hook 21, the central axis 213 being placed on a vertical line between the fixed lower axis 224 and the upper sliding axis 21 1.
- the articulated mechanism 22 thus controls, at the end of the rotation, a slight lifting of the hook 21 whose lower end 210 forming a latch engages from below in the ear 102 of the frame 10 of the upper crew 1 and, at the end of rotation, exerts on a locking pin 101, an upward thrust for firmly applying the frame 10 against the lower part of the pressure frame 34.
- the articulation of the mechanism on three axes coming in vertical alignment ensures the passage through a point of equilibrium with a knee-bracing effect that makes accidental unlocking impossible.
- the lower end 210 forming a hook latch 21 carries a sliding support member 214 with an enlarged head which is placed below the locking pin 101 by compressing a resilient member 215, for example a stack of washers Belleville, which allows passage through the equilibrium point.
- the cylinders 23, of the hydraulic or pneumatic type, can be remotely controlled so that the locking system of the frame 10 of the crew on the pressure frame 34 can be implemented without the intervention of an operator with a complete irreversibility and, consequently, a very high reliability of the fixing of the crew on the pressure frame.
- the cylinders could be mounted so as to be as little as possible exposed to the heat radiated by the product.
- the frame 10 'of the lower crew 1' which bears, at a constant level, on the bed base 34, can simply come into abutment in planing position. If necessary, however, one could use analog fasteners, also remotely controlled.
- each cassette forming a planing unit can be removed from the frame of the machine by sliding on rails on the bed base for the lower cassette or on the pressure frame for the upper cassette, in order to be placed on a disassembly trolley.
- a disassembly carriage is also used, but only to remove the upper cassette.
- the lower cassette is placed on a withdrawal platform placed next to the frame, then it is removed and replaced in this position by the disassembly carriage of the upper cassette.
- Figure 8 which shows, in perspective, the entire installation of the invention, we see that the withdrawal platform 4 forms the bottom of a pit 40 'formed in the floor 40 of the workshop next to the frame 3 of the leveling machine, the operator side.
- the withdrawal platform 4 is provided with a guide path 41, not shown. in detail, which is placed in the extension of guide rails 41 'formed on the bed base 32 of the machine and on which rollers 13 supporting the chassis 10' of the lower crew 1 '.
- the displacement of the cassette 1 ' is controlled by a jack 16 placed below the level of the withdrawal platform 4 and whose rod is provided with a removable fixing means on a fastening member 15 placed on a front side of the cassette 1 'at the platform.
- the lower crew 1 ' can be removed by a traveling crane to be placed, in the waiting position, on the service floor 40 of the workshop and replaced by a disassembly carriage 5 of the upper crew 1.
- This carriage 5 is provided, on a front face, with a fastening member 51 similar to the attachment member 15 of the lower cassette 1 'and on which can be fixed removably the end of the rod of the cylinder 16.
- the carriage 5 is provided with rollers 52 which, in this position, are placed on the raceway 41.
- the jack 14 can then bring the dismounting carriage 5 inside the frame 3 of the machine, as shown diagrammatically in FIG. 1 1, to receive the upper crew 1.
- FIG. 9 very schematically shows the various steps A to L of the process, according to the invention, of disassembly of the two planing crews.
- step A the two crews 1, 1 'are, in the operating position, inside the frame 3 of the machine, beside which, as indicated above, is provided the withdrawal platform 4
- the dismounting carriage 5 is placed in a position spread on the floor 40 of the workshop, close to the platform 4.
- the upper crew 1 being raised in the open position, the lower crew 1 'can be pushed by the jack 16 on the withdrawal platform 4, in the position shown in step B of Figure 9, and in the figure 10.
- the lower cassette 1 ' is then removed from the platform 4, to be deposited on the floor 40, next to the pit 40'. It is possible, for this purpose, to use a spreader 42 which rests, out of service, on a cradle 43.
- the industrial truck 5 is then taken over by the traveling crane and deposited on the guide path 41, in place of the lower cassette 1 ', in the position shown in step C of FIG. 9.
- the dismounting carriage 5 is provided with a removable attachment member 51 which engages on the rod of the jack 16 and the latter can then be actuated to return the dismounting carriage 5 to the inside the frame 3 of the machine, below the upper crew 1, in the position corresponding to step D of FIG. 9 and diagrammatically shown in FIG.
- the pressure frame 34 is then lowered to deposit the upper crew 1 on the disassembly carriage 5 and the attachment members 2 can then open to release the frame 34 which is reassembled.
- the upper crew 1 then rests on the dismounting carriage 5 which is pushed by the jack 16 so as to remove the upper cassette 1 of the frame to make it come on the withdrawal platform 4, in the position corresponding to the step E of Figure 9.
- the installation is also equipped with a handling bar 42 resting, out of service, on a cradle 43 on which can also be placed a new upper crew 1 a.
- This lifter 42 can be maneuvered by the overhead crane so as to support the upper crew 1 on the withdrawal platform 4, in the position shown in step F of FIG. 9.
- next step G the lifter 42 actuated, by the traveling crane, removes the worn upper crew 1 to put it on the worn lower crew 1 'placed next to the platform 4, in the previous step D. Then the lifter 42 comes to take over the new upper crew 1 arranged in advance on the cradle 43 and deposits it on the trolley of 5, in the position shown in Figure 12 and corresponding to step H of Figure 9.
- the new crew 1 a can then be brought inside the frame 3 by the industrial truck 5, in step I of Figure 9, by rolling on the guide rails of the pressure frame 34 which has been maintained. at the same level after the removal of the used crew 1.
- the coupling members 14 of the upper extensions 36 have also been maintained at the same level H2 in the manner that will be described below and can therefore be engaged, by axial sliding, on the journals 13a of the rolls of the new crew 1 a.
- the locking members 2 are then closed to secure the new upper crew 1a with the pressure frame 34 and the assembly can be reassembled in the position shown in Figure 13, thereby releasing the handling carriage 5 which is brought back by the jack 16 on the withdrawal platform 4 as indicated in step J of FIG. 9.
- the handling beam 42 is rotatably mounted on the cradle 43 around journals 42a and can therefore pivot about the horizontal axis thus defined in order to return the worn equipment 1, in the position shown schematically in step J.
- the working rollers of the upper crew 1 are thus turned upwards which facilitates their maintenance and possible disassembly for replacement.
- a new undercarriage is placed in advance on the workshop floor 40 near the withdrawal platform 4.
- the industrial truck 5 located in the stage J, on the platform 4 can be removed by the crane to be placed in the waiting position on the floor 40, for example, next to the new lower crew the a and it is then removed by the overhead crane to be placed on the withdrawal platform 4, in the position shown in step K of Figure 9, the attachment member 15a to be fixed on the end of the cylinder rod 16.
- the coupling members 14 'of the lower extensions 36' have been placed at the level H1 of the axes of the rollers 1 1 'a of the lower cassette a.
- the new lower crew can then be introduced into the frame 3 by rolling on the rails 41 'of the bed frame 32 to abut in its working position, the lower coupling members 14' engaging, by axial sliding, on the trunnions 13'a of the rollers of the crew a.
- the machine is equipped with two new crews, respectively upper 1a and lower the a and planing can be resumed.
- the worn crews can be taken to a maintenance workshop and replaced, near the machine, by new crews 1 b, the b.
- planing rollers of the two crews must be rotated through the elongations, respectively upper 36 and lower 36 'whose ends are connected to the respective rollers by removable coupling members 14 , 14 'which fit by axial sliding on the end pins 13, 13' of planing rollers 1 1, 1 1 '.
- This first level H1 corresponds to the height of the axes of the rollers 1 'with respect to the guide rails 41' of the bed base 32.
- each coupling member 14 'and of the journal 13' of the corresponding roller In order to allow interlocking portions of each coupling member 14 'and of the journal 13' of the corresponding roller to be interlocked without risk of damage, these coupling members 14 'must be placed at the same level H1 with respect to the bed 34 , during the reassembly of the lower cassette 1 'inside the frame 3 in the position shown in FIG. 13.
- the machine is therefore equipped with means for locking the coupling ends 14 'of the lower extensions to the first level H1 of disassembly of the lower assembly 1' and coupling ends 14 of the upper extensions 36 to the second level H2 disassembly of the upper crew 1.
- These locking means comprise three clamping plates which are shown in perspective in FIG. 14 and whose operation is illustrated by the figures 15 to 18.
- FIG. 14 shows, in perspective, all the locking means which are mounted, on the drive side, on the columns 31 'a, 31' b of the frame 3 of the machine and which comprise a lower plate 6 'extending horizontally between the two columns 31 'a, 31' and mounted on a bottom rail 60 ', an upper plate 6 mounted on an upper rail 60 and an intermediate plate 7 made of two pivoting parts.
- Figure 15 which shows the machine in planing position, the three plates are open the coupling members 14, 14 'being engaged on the journals 13, 13' of the rolls of the two crews.
- the lower crew 1 comprises six lower rollers 11' which are rotated, each by an extension 36 'and the upper crew 1 comprises five rollers 1 1 driven by extensions 36.
- each coupling member 14, 14 ' forms a sleeve provided with inner grooves and can rest on two spaced apart plates 61', of corresponding curved shape, provided on the lower plate 6 '.
- This plate 6 ' is carried by a cross member 60' which, in the example shown, rests on two mechanical cylinders 62 each mounted on a support 63 fixed on the bed base 32 of the machine, the two cylinders 62 being actuated in synchronism by a worm gear 64 driven by a motor.
- the cross-member 60 is thus guided vertically by the rods of the two jacks 62 and can therefore be lifted to take over the six coupling sleeves 14 'of the lower extensions 36' in the position shown in FIG. 16.
- the intermediate plate 7 is placed substantially at the level of the plane P of the product, between the two levels of trunnions 13, 13 'on which the extensions 36, 36' engage.
- the intermediate plate 7 thus comprises two parts 7a, 7b pivotally mounted around a vertical axis, respectively on two pivots 70a, 70b whose level can vary and whose opening and closing are controlled by means 8a, 8b.
- each pivot 70a, 70b is carried by a support member 81 on which are fixed the bases of two cylinders extending in opposite directions, respectively an upper cylinder 82 whose rod is articulated on one end of the cross member 60 carrying the upper plate 6 and a lower cylinder 82 'whose rod is articulated on one end of the crossbar 60 'carrying the lower plate 6'.
- the ends of the upper cross member 60 are mounted to slide vertically on slides 83a, 83b formed, respectively, on the two columns 31 'a, 31' b of the frame 3.
- each support piece 81 carries a rectilinear rack 85 having one end articulated on the half-plate 7a, 7b and on which meshes a pinion 86, rotatably mounted on the support piece 81 and can be driven by a crank, in the manner shown in FIG. 19, or by a motor controlled remotely if it is desired to avoid the presence completely an operator near the machine.
- the two crosspieces 60 ', 60 being connected at each end by a pair of opposed cylinders 82, 82', locked at this moment, this lifting of the lower plate 6 'causes a corresponding uplift of the upper plate 6 and the two parts of the intermediate plateau 7.
- the two semi-plates 7a, 7b which are aligned in order to reconstitute the intermediate plate 7, are then controlled to rotate in the manner shown in FIG. 16.
- the free ends of the half-plates 7a, 7b have conjugate profiles so as to fit into each other to give some vertical resistance to the transverse plate 7 thus reconstituted.
- this transverse plate 7 has on its underside six pairs of plates 71 'respectively corresponding to the lower coupling sleeves 14' of the six lower rollers 11 'and, on its upper face, five pairs of platens 71 corresponding to the upper sleeves 14.
- the upper plate 6 is provided on its underside with five pairs of plates 61 respectively corresponding to the coupling sleeves 14 of the upper extensions 36.
- the intermediate plate 7 thus formed is then slightly lowered by means of the lower cylinders 82 ' whose rods bear on the ends of the lower cross member 60 'held by the mechanical cylinders 62.
- the lower sleeves 14' are thus locked at this first level H1 in the position shown in Figure 17.
- This first level H1 is identified by keeping in memory, in the control system of the machine, the positions of the cylinders 62 at this time.
- the lower crew 1 ' can then be removed from the frame by means of the jack 16, as indicated in FIG. 10 and in step B of FIG. 9.
- the lower rail 60 ' can be raised by means of the mechanical cylinders 62 bearing on the bed 32, driving the lower coupling members 14' which remain tight between the lower plate 6 'and the intermediate plate 7 which is also raised by the lower rail 60 '. Indeed, the two pairs of jacks 82, 82 'being blocked, the vertical displacement of the lower cross member 60' controls a corresponding uplift of the intermediate plate 7 whose support members 81 slide along the slideways 84, and that of the upper cross member 60 whose ends slide in the slideways 83a, 83b.
- the assembly formed by the lower cross member 60 ', the coupling sleeves 14' and the intermediate plate 7 is thus raised until the upper plates 71 of the intermediate plate 7 come to support the coupling sleeves 14 of the upper extensions, centered at the H2 level.
- the cylinders 82 then control the lowering of the crosspiece 60 so that the plates 61 forming the upper plate 6 are tightened, in the position shown in Figure 18 and also corresponding to Figure 12, on the set of upper sleeves 14 resting on the intermediate plate 7 and the lower cross 60 'maintained by the cylinders 62.
- the upper cross member 60 is spaced apart by the jacks 82 to release the upper couplings 14 and the new crew 1a is raised by the pressure frame 34.
- the mechanical cylinders 62 then control the lowering of the lower cross member 60 'and the intermediate plate 7 with all of the lower sleeves 14' which are thus brought back to the first level H1, previously identified, as shown in FIG. 13.
- the invention is not limited to the details of the embodiment which has just been described as a simple example and which could be the subject of variants using equivalent means, remaining in the same protective frame.
- other types of coupling means could be used, for example jaw claws that could be maintained at the desired level for disassembling and reassembling the cassettes.
- the pivoting intermediate half-plates 7a, 7b could also be controlled remotely to avoid any intervention of an operator.
