Definitions

  • ABSTRACT A storehouse with parallel corridors containing pallets, with a self-propelling selecting trolley adapted to take the pallets on to a transfer device rolling on a track perpendicular to the corridors and possibly into an elevating device, the control originating from a central point.
  • the motive power and the control signals between the control point, the transfer trolley and the self-propelling trolley are transmitted by cables, continuity being assured on the various routes by winding drums and movable cables, provision being made so that the carrying device cannot move until the carried device attached through its winding-drum to the cable has engaged with the carrying device.
  • the invention concerns a stock-handling system comprising a load-carrying trolley which can withdraw and set down pallets in storage corridors, the trolley being provided with special arrangements for the supply of its motive power and control signals, which allow it to leave the corridors and, if necessary, to be carried in one or two directions perpendicular to the corrigors while remaining in contact with its supply, which may originate from a central command post.
  • the invention remedies these disadvantages by a cable system which allows continuity of supply when the trolley leaves its corridor and when it is transferred one or more times in other directions by at least one transfer device.
  • the system of the invention thus permits the linking, in a reliable way, of the control of one or more handling trolleys which deal with a surface or a volume or storage spaces, to a single control station situated at any level outside the storage area.
  • the trolley being provided with a loading device and a remotely controlled automatic selector, and being self-propelled and guided on rails
  • the power and the control signals are transmitted to the trolley along the corridor by at least one cable attached and connected outside the said corridor, the cable being wound on a winch fixed to the trolley and terminating on the latter through slip-ring connectors which supply the trolley components, while means are provided on the winch to ensure the winding on or off of the cable to keep it taut between its point of attachment and the trolley, according as the trolley advances or retreats in its corridor.
  • the winch drive is achieved by mounting it on a shaft which can be driven in one direction only by two driven wheels coupled respectively to a first and a second driving wheel which are fixed to a single shaft driven by the trolley wheels, the first driving wheel driving the first driven wheel in the same sense as itself through a freewheel connection so as not to act in the sense opposite to that of the winding shaft, the second driving wheel driving, with inversion of sense, the second driven wheel through a free-wheel connection so as not to act when the driving shaft acts on the first driven wheel, while there is interposed between the shaft carrying the two driven wheels and the winch shaft, a friction coupling with calibrated torque, so that as the trolley approaches the point of attachment of the cable the two first driving and driven pulleys, acting in the same sense, turn the winch to wind in the cable, and as the trolley moves away from the point of attachment it pulls on the cable to unwind it, but the other two driving and driven wheels tend to turn the winch shaft
  • the system of the invention can be applied to a storage installation comprising a number of parallel corridors which are served by a perpendicular alley along which travels a transfer device on rails, the trolley being capable of fitting on the transfer device, where its cable is attached and joined with a second supply device with mobile cable, itself attached to a fixed point, means being provided to stop the transfer device in a predetermined position according to which corridors the trolley has to work in.
  • the second device with mobile cable may be a second winch system identical with the first and installed on the transfer device.
  • a second application of the system of the invention concerns a storage installation comprising a number of levels of parallel corridors with a facade along which travels perpendicularly to the corridors, a transfer device comprising a trolley which moves on a track at the lowest level, the trolley having one or more elevator columns carrying a loading platform on to which the trolley coming from one of the corridors can be fitted, this system comprising the same elements as in the preceding case, but with a supplementary vertical winder to connect the trolley and platform cables.
  • a storage installation comprises at least one storage level which is above an access level, the said storage level having a number of parallel corridors ending in a transfer alley with a transfer device on rails, the transfer alley including the loading surface of a lift capable of receiving the transfer device and its load, the transfer device comprising a winch whose cable ends at the lift platform and can be connected to the cabin, means of control being provided to co-ordinate the position of the lift cabin with the level where the transfer device is working, and at least one mobile feed cable for this device being provided between the lift cabin and the fixed part of the building.
  • the trolley can, as before, fit on the transfer device and stay there when this device moves vertically in the lift.
  • FIG. 2 is a perspective to show the arrangement for winding the winch.
  • FIG. 3 is an end view of the trolleyand cable guides.
  • FIG. 4 is a plan view of the load-carrying trolley.
  • FIG. 5 is a schematic layout of corridors and a transfer alley.
  • FIG. 6 is a schematic perspective of one way of joining the mobile cables of the trolley and the transfer device.
  • FIG. 7 is a perspective view of an application with a transfer device.
  • FIG. 8 is a schematic perspective of a multilevel storage installation with an elevator on a trolley.
  • FIG. 10 is a variant, shown schematically, of a transfer device able to collect two trolleys and to take them into the lift.
  • FIG. 11 is a schematic view of the connections between the transfer device and the lift.
  • FIG. 1, 1 indicates an automatic handling trolley which can move along channel-section rails 2, 3 which follow the line of the corridor in which they are installed.
  • the trolley is of the type described in the French Patent Application no. PV 84 689 of 23 Nov. 1966, with however certain differences of construction which will appear below. It is supported by rollers 4 on the flanges 2a and 3a of the corresponding rails.
  • the upper surface 5 of the trolley can be raised and lowered by a device in the interior and in its lowered state is slightly below the upper flanges 2b, 3b of the rails, so that on being raised it picks up a pallet placed on the rails, such as can be seen in FIG. 7.
  • the storage corridor ends at a loading and unloading station shown at 6 on the left of FIG.
  • FIG. 4 The construction of the trolley is shown in FIG. 4, FIGS. 1, 2 and 3 being intended to show the main features of its working.
  • the trolley is self-propelling on the rollers 4, whose axles are joined through a transmission to a motor on the trolley.
  • the power and the control signals are sent to the trolley through an automatically unwinding cable 7, which in the example of FIG. 1 is connected at its end 7a to a fixed power outlet 8 at the unloading station.
  • the cable passes under the trolley and enters from below, being guided by a device 9 of normal construction on to the drum of a winch 10.
  • the diameter of the winch is sufficiently small for it to be mounted within the thickness of the trolley 1.
  • the chain 20 is driven by a drive originating from the movement of the trolley.
  • a first transmission between shafts 15 and 18 consists of two aligned pulleys 21 and 22 mounted respectively on one and the other shaft and connected by a belt 23.
  • Pulley 22 is keyed to shaft 15, but pulley 21 is mounted on its shaft 18 through a freewheel device 24 in such a way that pulley 22 can only be driven in the sense F which corresponds to the sense F of the chain 20 and to movement 8, of the trolley, which is towards the station 6.
  • a second transmission between shafts l5 and 18 is provided by two toothed wheels 25, 26 which mesh with each other to give opposite directions of rotation to the two shafts 18 and 15.
  • wheel 26 contains a free-wheel device 27 which allows shaft 15 to be driven by this second transmission only if the chain 20 moves in the opposite sense F which is the sense corresponding to movement of the trolley away from the point of attachment of the cable (sense S It follows that, if the trolley moves towards its point of attachment (sense S pulleys 21, 22 are operative and the winch winds in the cable if the coupling 17 allows.
  • this coupling is of the electromagnetic powder type and it is calibrated to ensure the drive between shafts 14, 15 for the normal winding torque.
  • the trolley whose construction is shown in FIG. 4, is a box open at the top, with a bottom 31 and sides 32, 33 (see also FIG. 3).
  • Interior cross-members and braces 34, 35 and anglepieces 36 allow the fixing of the different elements.
  • the trolley is carried on two sets of rollers 4 at either end, the rollers being keyed to transverse axles 37 which pass through blocks 38 fixed to the sides 32, roller bearings 39 being interposed between the axles and the blocks.
  • the other pair of axles 37' mounted similarly to the first pair, are coupled by means of chain wheels 42; also on one of them is mounted a control pinion 43 which drives the previously mentioned chain 20, an intermediate guide pinion 44 being provided.
  • the centre of the box contains the winch device whose function has already been described with reference to FIG. 2.
  • a box 45 encloses the parallel shafts l5 and 18. Connecting these shafts are the meshing wheels 25, 26 which reverse the sense of rotation and the pulleys 21 and 22, which in this case are toothed wheels turning in the same direction by means of the chain drive 23.
  • This shaft also carries a pinion 46 which drives the cable guide 9 by means of a chain 47.
  • This known device receives the cable arriving at the trolley through an opening in its base and the two rollers 48, 49.
  • the cable which is not shown on FIG. 4, ends in the winch l0 inside the slip-rings 11, which have sliding contacts underneath each ring.
  • the trolley also contains four cams 50 to raise its upper surface. At one end of the trolley two cams 50 are fixed to a transverse shaft 51, which carries chain drives 52 to two cams at the other end.
  • the shaft 51 carries a chain drive 53 linking it with the lifting motor 54.
  • FIG. 1 The arrangement limited to the form of FIG. 1 permits the stowing and withdrawing of storage pallets in a single corridor and loading or unloading them successively at the end. It is also possible to have a number of parallel corridors containing pallets, with the possibility of moving pallets from one corridor to another by means of a single trolley which can be transferred perpendicularly in an alley V at the end of the corridors.
  • FIG. 5 This system is schematically represented by FIG. 5, in which the trolley 1, which is in corridor B, is able to move on to a transfer device 100 mounted on rails perpendicular to and lower than the corridor rails. Movement of pallets can be effected between one or other of the corridors A, B, C and D. It can also be arranged to move pallets from an entrance E into a corridor, or
  • Commands and instructions must necessarily be provided to send the device 100 to corridor B, to order the movement of the trolley l with its load on to the transfer device 100 and to send this last to another corridor for the inverse manoeuvre.
  • the electric connections are made entirely by mobile cable as is shown in FIG. 6.
  • the trolley 1 moves in corridor B while drawing in its cable 7, whose end is this time joined to a connector 108 fixed to the transfer device 100.
  • This last carries a second winch 110 with a collector 111 joined through its sliding contacts to the point 108.
  • the cable 107 of the winch 110 may end at a junction box leading to a control and power distribution station.
  • the transfer device is closely linked with the trolley, and that it cannot move so long as the trolley operates in a corridor and has not remounted the transfer device. This, however, is not imperative if the point 108 can be disconnected manually or automatically, i.e. if the transfer device can abandon a trolley in a corridor.
  • FIG. 7 gives a view of an actual installation following the layout of FIG. 5. It shows, moreover, a two-tier sys tem of storage corridors served by a single transfer device which moves perpendicularly.
  • the two storage levels are parallel and identical, the advantage of this arrangement being evidently to save one transverse track with a corresponding motor device.
  • An elevator not shown and not forming part of the invention, allows transfer of pallets between the two levels.
  • the single transfer trolley comprises a framework formed of a movable base with two parallel chests 55a, 55b transverse to the track of the alley, on which they roll.
  • the sides of the chests 55a, 55b are provided with rail sections 112, 113 which correspond to the tracks in the lower-level corridors.
  • the trolley 100 is surmounted by two pairs of legs 57a, 57b, 57c and 57d, each pair joined by a cross-member 58 and forming a trapezoidal arch. These arches are out away at the top to form a cradle 59 whichcorresponds to an extension of a track from an upper corridor.
  • the sides 60 of the cradle support lateral rails 2 and 3', while a U-iron 28 rests on the middle of the cradle.
  • the trolley lb of the lower corridors in FIG. 7 is arranged in the same way.
  • the two levels of corridors forming the rows labelled A, B, C as in FIG. 5 are superposed by means of a metal framework comprising horizontal beams 62 and vertical beams 61 which are the normal components of metal framework, not further described in detail.
  • a sliding track 63 in the form of a hollow rail which supports moving hooks 64 on to which the straps of the hanging cable 107 are attached.
  • This cable system 107 is functionally equivalent to the cable-winding system shown in FIG. 6.
  • the cable 107' contains sufficient conductors to control both automatic trolleys 1a and lb.
  • parallel storage corridors are situated on several levels, for example:
  • level 0-A B C etc. level l-A B C etc. level 3-A B C etc.
  • An elevating trolley 200 moves on a track V perpendicular to the corridors and along their frontage.
  • the corridor assembly is somewhat elevated above a substructure G so that the platform 64 of the elevator is able to get .down to level 0.
  • the elevator 200 is a known type of trolley with a horizontal table guided by vertical columns and operated by jacks or by a screw.
  • the table 65 supports a platform 66 which is adapted for the invention.

It is clear that the elevating trolley constitutes the transfer device, as did the trolley 100 of the preceding example.
  • the trolley 200 is provided with a constant tension winder 210 for its cable 207, this last being anchored and connected to a fixed control post P. Further, the electrical continuity between the base of the elevator 20] and its mobile platform is ensured by a second winder 220 which is situated in the body of the trolley. The winder 220 unwinds a cable 221 vertically, this cable being attached at 208 on the platform 66 to the end of the cable 7 of the automatic trolley 1.
  • the winder 220 may be of a known type employed in lifts. It is provided with collecting rings which are joined to the rings of the winder 216. Thus the electrical continuity from the control post P is achieved through the horizontal cable 207, the vertical cable 221 and the cable 7 of the trolley 1.
  • the invention may be applied to an installation with corridors on a large number of levels and with a lift for vertical service, as is shown schematically in FIGS. 9, 10 and II.
  • the route V of the transfer trolley 100 is interrupted by the shaft T of a lift 300.
  • the disposition of the transfer device 100 and the automatic trolley 1 is the same as in FIG. 6, with winders respectively 110 and 10, the transfer device moving on rails 102 and 103 of the track V.
  • the cable 107 of the winder 110 is fixed to the platform 310 of the cabin 300 of the lift, in a junction box designated generally by 308.
  • a hanging cable 307, as normally used for the control of lifts, is connected to this junction box.
  • the cabin will have two hanging cables, one to control trolley 1 and the other for the normal lift controls.
  • a possible sequence of events may be as follows: the arrival of trolley l on trolley 100 authorises the movement of trolley 100 the arrival of trolley 100 on the lift platform 310 authorises the movement of the lift the stopping of the lift at the required floor authorises the departure of trolley 100 the stopping of trolley 100 in front of the required corridor authorises the departure of trolley 1 from trolley 100.
  • Automatic load-carrying system for storehouses having a number of parallel corridors with a frontage for entering and leaving on at least one level, the said system being provided with a loading device comprising a self-propelling trolley adapted to take the loads and to put them on any point of a corridor, a transfer device rolling on a track perpendicular to the corridors, means for removably fitting the trolley on the transfer device, means for rolling the transfer device along the track and for stopping it opposite a predetermined corridor in which the trolley is to work, and an automatic selector controlled from a distance, the motive power and the control signals being transmitted to the loading device by at least one cable fixed under the trolley and connected to the outside of the working area, the cable being wound on a winch fixed to the trolley and ending on it at a slip-ring connector for supplying the trolley, means being provided on the winch for ensuring, according to the direction of travel, the winding or unwinding of the cable so that it remains taut between its groove having two edges serving as guides for pairs of rollers fixed to
