Definitions
- the present invention relates to a device intended for the arrangement, storage and controlled distribution of small objects and in particular of keys.
- the technique most used to ensure this type of management consists of storing the keys by placing them inside a traditional key cabinet fitted with hooks provided with identification means. Each hook thus receives one or more keys from a given lock and, under these conditions, the user wishing to have a stored key either addresses himself to a person responsible for storing and distributing the keys or carries out himself storing and collecting the keys he needs.
- This classification method has notable drawbacks which are due to the fact that, due to its manual nature, it cannot be used to ensure the safe and efficient management of a large number of keys.
- devices have been proposed for the automatic classification of spare parts of a car which consist of a series of columns and rows of cells, thus forming a matrix, the contents of each cell being accessible by robotic means controlled in particular by computer.
- This type of device makes it possible to efficiently manage a very large number of small objects but has the drawback of requiring complex and expensive servo mechanisms.
- the object of the present invention is to propose a device for storing small objects, and in particular keys, which is particularly suitable for automated management, in particular computer-controlled management, and which is of a particularly simple and inexpensive constitution.
- the present invention thus relates to a device intended for the arrangement, storage and controlled distribution of small objects, such as in particular keys, comprising a housing and a series of cells intended to each collect at least one object, characterized in that the cells are arranged on a drum in the form of a cylinder of revolution, mounted for rotation about its axis disposed horizontally, each of said cells comprising at least one access orifice which opens on one of the bases of the drum and which are grouped by successive series of orifices, each orifice of the same series belonging to the same radius of a base of the drum, this device comprising means for controlling and indexing the drum capable of bringing the latter into respective positions such that each of said series of orifices can be arranged according to a fixed radius determined relative to the housing , and means for addressing and accessing each of the orifices in the series of orifices arranged along said determined fixed radius.
- the cells are inclined relative to the axis of rotation and are closed by a fixed wall relative to the housing, this fixed wall being pierced by two rectangular windows which extend vertically and radially respectively above and below the axis of rotation, and which respectively communicate with the outside of the drum
- the addressing and access means comprise the access orifices of two diametrically opposite series cells of the means for closing off each orifice of the two said series of cells, individually addressable, being provided in each window.
- the cells are of cylindrical shape and their respective axes of symmetry are arranged along successive radial planes of the drum.
- the shutter means consist of shutters.
- each flap is pivotally mounted in a duct, so as to occupy two positions, namely a first position in which it ensures closing the access orifice of a cell opposite which it is arranged, and a second position in which it frees access to said orifice.
- the flap when it is in the second position, closes the cross section of the duct, so as to guide an object in or out of a cell.
- the means for controlling and indexing the position of the drum can comprise a stepping motor engaged therewith and logic and counting means capable of controlling the rotation of the stepping motor by the number of pitch corresponding to a rotation of the drum such that the series of orifices to which the selected cell belongs is positioned according to said determined fixed radius.
- the position of the access orifice of a specific cell is determined in a coordinate system of the polar coordinate type, namely on the one hand by the trigonometric angle formed by the series to which said part belongs.
- specific cell with respect to a reference series and, on the other hand, by the distance of this specific cell from the center of the drum.
- FIG. 1 is a front sectional view of an embodiment of the device according to the invention, along the line I-I of FIG. 2.
- FIG. 2 is a cross-sectional view of this same device, along line II-II of FIG. 1.
- Figure 3 is a partial view, on a larger scale, of Figure 2, showing storage cells located below the axis of rotation of the storage drum, in which a shutter for closing one of these alveoli is in the open position.
- Figure 4 is a partial view on a larger scale of Figure 2, showing storage cells located above the axis of rotation of the storage drum, in which a shutter shutter of one of these cells is in the open position.
- Figure 5 is a partial front view, on a larger scale, of the drum used in the device according to the invention.
- Figure 6 is a front sectional view of the embodiment shown in Figures 1 to 5, along the line VI-VI of Figure 2, the feed and recovery chutes being removed.
- Figure 7 is a partial sectional view of an alternative embodiment of the invention showing the lower part of the storage drum and means addressing and access to each of the orifices of the cells of the same series.
- Figure 8 is a partial view along line VIII-VIII of Figure 7 of the addressing means and access to each of the orifices of the cells of the same series.
- Figure 9 is a partial sectional view of an alternative embodiment of the invention.
- Figure 10 is a sectional view along line X-X of Figure 11 of an embodiment of the invention.
- FIG 11 is a sectional view along line XI-XI of the embodiment of the invention shown in Figure 10.
- the device according to the invention comprises a parallelepipedal housing 1 to the inside of which is disposed a cylindrical drum 3 provided with a hub 5 rotatably mounted on bearings 7 with a horizontal axis xx ', integral with the housing 1.
- the drum 3 is delimited by a cylindrical peripheral wall 9 and by a flat bottom 11 perpendicular to the axis xx '.
- the drum 3 contains a plurality of cells 12 each intended to accommodate keys. These cells 12 are formed from elements of cylindrical tubes 15, of rectangular section, one end of which is applied against the wall 11, so that the latter constitutes a bottom of each of the cells 12.
- the tube elements 15 are assembled together, and fixed to the drum, in particular by gluing, so as to constitute a given number N of series of tube elements 15.
- the tube elements 15 of the same given series are arranged so that their respective axes of symmetry are located in a radial plane of the drum 3 and are inclined at a given angle a relative to the axis of rotation xx 'thereof.
- the tube elements 15 situated below the axis xx ′ are thus inclined from the top to the bottom when one goes (in FIGS. 2 and 3) from the center of the box 1 towards the outside thereof and in the opposite direction for the tube elements 15 situated above the horizontal axis xx '.
- the other end of the tube elements 15 is closed by a vertical wall 17 secured to the housing 1.
- This wall 17 is pierced by two rectangular windows (FIG. 6), namely an upper window, or recovery window 19, and a window lower, or loading window 19 ′, which extend vertically and radially, respectively above and below the hub 5.
- the windows 19, 19 ′ open on respective conduits of rectangular section, namely a conduit upper 21, or recovery duct, and a lower duct 21 ', or loading duct.
- the recovery conduit 21 opens, at its lower part, onto a recovery chute 23 which opens into the front wall 25 of the housing 1, through an orifice 27 which terminates outside the housing 1 on a recovery tank 29 .
- the loading duct 21 ' opens, for its part, at its upper part, onto a loading chute 23' which opens into the front wall 25 of the housing 1 through an orifice 27 '.
- the peripheral wall 9 of the drum 3 is provided with a toothing 28 engaged with a pinion 31.
- This pinion 31 is integral with rotation drive means, which may consist, in particular, of a stepping motor, or any other drive means capable of being controlled by indexing means, a primary function of which is to allow the positioning of any series of cell orifices 12 facing one of the windows 19, 19 'and a second function of which will be specified below.
- the wall 17 in which the windows 19, 19 ′ are produced is provided with a series of flaps 30, mounted articulated around horizontal axes 32, and which are of dimensions close to the orifices 13 in the cells 12.
- These flaps 30 are provided control means allowing them to occupy two positions, namely a first position in which they ensure the closure of the cell 12 in front of which they are arranged, and a second position, or open position, in which they provide the extension of the "floor" of a cell (for the cells arranged below the axis of rotation xx ') or the "ceiling" of a cell (for the cells arranged above the axis of rotation xx ').
- the flaps 30 can for example be actuated by electromagnets, not shown in the drawing.
- the second function of the control and indexing means is to activate or deactivate the electromagnets controlling the opening of the flaps 30.
- the latter are provided with return means such as springs, not shown in the drawing, which, in the absence of solicitation of the electromagnets, apply them in the closed position.
- the control and indexing means position the drum 3 so that the series in which the determined cell is located is located opposite the vertical loading window 19 '.
- the access means ensure the excitation of the electromagnet controlling the opening of the flap 30 allowing access to the cell 12 in which one wishes to store the key.
- the user introduces said key through the orifice 27 'provided in the housing 1, and the latter descends by gravity into the loading chute 23' then into the loading conduit 21 ', up to that it comes into contact with the open flap 30 which, like a switch, then directs it into the cell 12 chosen.
- the excitation of the electromagnet is cut, so that the flap 30 resumes its closed position of the cell, under the effect a return spring.
- the control and indexing means rotate the drum 3, so that the series of cells in which is located the cell 12 containing the key is facing the recovery window 19.
- the slope of the cells 12 is directed in the direction reverse, namely downwards, so that it suffices to control the opening of the flap 30 closing the inlet of the cell 12, by exciting its electromagnet, to allow the key contained therein to descend by gravity in the recovery duct 21, then in the chute 23 and finally in the recovery tank 29.
- the excitation of the electromagnet of the shutter 30 is cut off , so that it resumes its closed position of the cell 12, under the action of its spring.
- the device can be controlled by semi-automated or fully automated management means.
- control and indexing means determine the angle of rotation that the drum 30 must perform to position the series containing the cell considered facing either the recovery window 19 or the storage window.
- the search for the coordinates of a cell is entrusted for example to a microcomputer which has, in a memory file, the references of the key and the coordinates thereof. and which automatically controls, by means of an interface, on the one hand the rotation of the drum 3 in order to bring the series of the cell associated with the key in question facing the recovery or storage windows, then the excitation of the electromagnet ensuring the opening and then the closing of said cell 12.
- each cell may include means for determining whether or not it contains a key.
- These means can for example consist of a proximity detector reacting to the presence of a metallic mass in the cell 12 or, on the contrary, consist of two conductive elements insulated from each other, namely a conductive element 40 disposed in the "floor” and a conductive element 40 'disposed on the bottom of the cell 12, which are brought into electrical contact with each other by the presence of a key in this cell 12.
- the cells 12 can be inclined in the opposite direction, namely from the bottom up when going from the center of the housing 1 outwards, for the cells located below the axis xx '.
- the positions of the loading conduits 21 ′ and recovery 21 are reversed.
- the cells 12 can also be formed by any means other than the assembly of tube elements. They can in particular be obtained by machining in the mass of the drum 3, folding and welding, etc.
- the addressing and access means to each of the cells of a series of cells do not consist of flaps controlled by electromagnets but of a loading duct 50 formed by a set of tubes 52 mounted to slide in one the others so as to form a telescopic assembly ending at its downstream part, or lower in FIGS. 7 and 8, by a distribution “nozzle” 54 which opens in the immediate vicinity of the access orifices 13 of the cells 12.
- the lower element 56 of the telescopic assembly comprises two lateral longitudinal bosses 58, each traversed by an endless screw 60, which are engaged therewith. Control means rotate the worm screws 60 so as to position the opening of the nozzle 54 in front of the orifice 13 chosen from the series of orifices located opposite the lower window 19 '.
- This embodiment thus replaces the addressing means constituted by the flaps 30 and the electromagnets controlling the opening thereof.
- means are provided for subjecting the drum to vibrations during the introduction or removal of an object, so as to avoid jamming thereof, or to allow his release if he's stuck.
- Means may be available in different places according to the invention for ensuring monitoring of the important areas of the device so as to control the proper functioning or, on the contrary, detect an operating anomaly.
- a surveillance camera 70 which makes it possible to control whether the keys distributed by the "nozzle" 54 are properly brought to their final destination, namely in a cell 12.
- the monitoring devices can be devices able to be triggered and implemented remotely, using in particular telephone lines or radio link means.
- FIGS. 10 and 11 show means of access to each of the cells 12 of a series of cells which are accessible through the upper window 19 produced in the wall 17.
- This has thus been produced in the recovery duct 21 a succession of shutter flaps 30 which are pivotally mounted around vertical axes 32 ′ and which ensure the closure of all the cells which open onto the upper window 19.
- a toothed pinion 72 centered on the axis 32 ′, is secured to the flap 30 and is engaged with a horizontal rack 76.
- the rack 76 extends out of the duct 21 and carries, at its external end, a head 78. Under these conditions, any traction on the head 78, directed along the arrow G has the effect of causing the flap 30 to open by rotating it inside the duct 21.
- Elastic return means are provided on each rack 76 to bring the latter back at his rest position and thus ensure the shutter position 30.
- each of the racks 76 is carried out by a claw 80 secured to an axis 82 of an electromagnet 84 which, when excited, moves the claw 80 in the direction of the arrow G.
- the electromagnet 84 is disposed in a housing 85 provided with a nut 86 which is engaged with a vertical endless screw 88. By conferring on the endless screw 88 a rotation of an appropriate number of turns, it is thus possible to position the claw 80 of so that it can request any of the racks 78.
- This device thus makes it possible to control the opening of any of the flaps 30 closing a series of cells disposed in the window 19.
