Definitions
- the present invention relates to a pneumatic device and an object sorting system comprising the pneumatic device.
- Patent US20160016200 describes a pneumatic device for sorting products in the food industry, such as seeds or grains of rice or wheat.
- the device comprises solenoid valves each having a series of air jet orifices.
- the solenoid valves each include an air inlet in a compartment; the air is then distributed in each orifice via a respective valve opened by the electrification of a coil or kept closed by an elastic member.
- the pneumatic device of this document being intended for sorting seeds, it has a large number of orifices expelling jets of air which must all be of the same volume. This makes it cumbersome and imprecise.
- the invention proposes a pneumatic device, comprising - modules, each module having compressed air supply valves, the intensity of the jet of compressed air supplied by each module being variable according to the combination of activated valves,
- the modules are fan-shaped relative to the nozzles.
- the modules respectively have a duct directing the compressed air from the valves to the nozzles, the valves being on either side of the duct with respect to the direction of flow of the compressed air in the duct.
- valves are connected by an orifice to the conduit, each valve having a different orifice diameter.
- valves are arranged along the conduit according to the diameter of the orifices, the valve with the smaller diameter orifice being at the distal end of the conduit relative to the nozzles.
- the device comprises six modules, each module comprising at least four valves, preferably five valves.
- the device further comprises a pressure sensor at the inlet of the modules, capable of measuring the pressure drops caused by successive openings of the valves.
- the invention also relates to a system for sorting objects, comprising at least one pneumatic device as described previously.
- the system further comprises a channel guiding the objects in a running direction, the nozzles directing one or more jets of air in the channel towards the objects to be sorted according to the characteristics of the objects to be sorted.
- the channel has an adjustable width transversely to the direction of scrolling of the objects according to the characteristics of the objects.
- system further comprises
- the system further comprises a control unit activating all or part of the modules and the valves according to the characteristics of the objects analyzed in the analysis chamber.
- control unit activates all or part of the modules and the valves as a further function of the pressure available upstream of the valves.
- the invention relates to a pneumatic device, comprising modules, each module having compressed air supply valves.
- the intensity of the compressed air jet supplied by each module is variable depending on the combination of activated valves.
- the device further comprises outlet nozzles for one or more jets of air coming from the modules, depending on the number of activated modules, the nozzles having aligned outlet orifices.
- Such a device combines the adjustment of the number of air jets at the outlet with the intensity of the air jets. This makes it possible to apply a deflection force to objects that one wishes to sort very quickly with a precision adapted to the characteristics of the objects while limiting the size of the device.
- FIG. 1 illustrates a schematic view of part of the pneumatic device 10.
- the device 10 comprises modules of which only the module 100 is represented. Other modules comprising the same elements are represented in FIGS. 2 and 3.
- the module 100 comprises a plurality of valves 12, for example four or five in number as can be seen in FIG.
- the valves are supplied with compressed air from a tank of sufficient volume (minimum 5 litres, maximum 15 litres) and whose pressure is precisely regulated by a precision pressure regulator; this ensures the most stable possible supply to the valves 12.
- the valves 12 are thus supplied via a supply conduit 11.
- a pressure sensor 15 on the supply conduit 11 is able to measure the pressure drops caused by successive openings valves.
- the pressure sensor 15 makes it possible to correct the opening of the valves 12 according to the pressure present at the inlet.
- the valves 12 may or may not be identical within a module or from one module to another. When the valves are the same, this makes it easier to control the valves; different valves allow even finer control.
- the valves 12 can be of different types, such as proportional valves but preferably “all or nothing” type valves.
- the "all or nothing” valves are very reactive, which is an advantage in the case of high rate of scrolling of objects. Also, these “on/off” valves are smaller in size. It is preferable to use a plurality of smaller valves rather than one larger valve capable of passing a large flow at full opening.
- the opening time of the valves 12 is less than 3 ms, preferably less than 2 ms, preferably less than 1 ms.
- the module 100 further comprises an air jet outlet nozzle 14 coming from the module 100.
- the intensity of the single jet of compressed air supplied by each module 100 is variable depending on the combination of valves 12 activated .
- the modules 100 can be selectively activated and, within each module 100, the valves 12 can be selectively activated. Each roll is therefore proportional to the characteristics of the objects to be sorted.
- the nozzle 14 makes it possible to best position the jet of air specific to each module with respect to the objects to be sorted.
- the nozzle is a duct machined in a casing 16, the casing 16 then being fixed to the module.
- the geometry of the nozzle exit orifice is chosen according to the characteristics of the air jets. A non-circular geometry, oval for example, can be advantageous.
- the set of nozzles can be an interchangeable modular element of the device 10 in order to adapt to the conditions of use of the device and of the objects to be sorted.
- the diameter of the outlet orifice of the nozzle is between 1 mm and 8 mm, preferably between 2 mm and 5 mm, more preferably between 2.5 mm and 4 mm, for example 3 mm, to obtain an air jet per module allowing efficient sorting .
- the module 100 further comprises a duct 18 directing the compressed air from the valves to the nozzle 14.
- the arrow 20 indicates the direction of air flow in the duct 18 up to the outlet of the nozzle 14.
- the valves can be placed along the duct 18 within a module.
- the valves 12 are on either side of the conduit 18 with respect to the direction of flow of the compressed air in the conduit 18 within a module; in other words, the valves are in opposition (without necessarily being opposite each other) or on both sides of the conduit 18.
- Such an assembly of the valves makes it possible to reduce the volumes necessary in the device (both the space occupied by the valves than the volumes of the ducts).
- the conduit 18 is thus more compact at the level of the valves 12.
- the conduit 18 may comprise several sections arranged to take into consideration the size of the valves within the module. Also, these sections make it possible to arrange the valves within a module and the modules relative to each other while ensuring the same pressure drop between the different modules.
- the length of conduit 18 is as short as possible to minimize the distance between the outlet orifices of the valves and the outlet orifices of the nozzles.
- the conduit may comprise a first section 181 to which the valves 12 are connected as described above.
- the duct 18 may comprise a second section 182 connecting the first section 181 at its end to the nozzle 14.
- the arrangement of the second duct 182 within the module is chosen so as to reduce the size of the modules within the device.
- the second section 182 may be oblique relative to the first section 181, and is preferably straight, which generates less pressure drop.
- the diameter of the duct 181 is between 2 and 5 mm, preferably between 2.5 and 4 mm, for example 3 mm and the diameter of the duct 182 is between 3 and 6 mm, preferably between 3.5 and 5 mm, for example 4 mm - this ensures a jet of air at the outlet of the device allowing efficient sorting of objects while limiting the size of the ducts.
- the conduit 18 opens at its end 183 to the output of the module 100; the nozzle 14 is positioned at the end 183 of the module 100 and precisely directs the jet of compressed air specific to each module towards the objects to be sorted.
- valves 12 are connected to the pipe 18, in particular to the first section 181, by outlet orifices 13. Each valve has a different orifice diameter 13. There may be a relationship between these ducts 13, in terms of diameter or area. This makes it possible to vary the intensity of the air jets.
- 'x' is the number of valves 12
- 2 X is the number of possible combinations of valve opening, one of which corresponds to all valves closed.
- valve 12 with the smaller diameter orifice is at the distal end of conduit 18 relative to nozzles 14; this prevents the flow of air propelled by the valves with a smaller diameter orifice in the duct 18 from being disturbed by the turbulence of an air flow propelled by the valves with a larger diameter orifice.
- valve outlet orifices are between 0.4 and 3 mm, preferably between 0.5 and 2.5 mm. This allows rapid release of the compressed air in the conduit 18 while limiting the size of the valves.
- FIG. 2 illustrates a sectional view of the pneumatic device 10.
- the device 10 is mounted in a casing 80.
- the nozzles 14 are represented at the outlet of the device 10, expelling air jets 20, and are connected to the ends 183 ducts 18 supplied by the valves 12.
- the orifices of the nozzles 14 are aligned.
- the orifices of the nozzles 14 are in the same plane.
- the orifices of the nozzles have a spacing (between the central axes) of between 3 and 5 mm, preferably between 3.5 and 4.5 mm, more preferably 4 mm, to ensure both compactness of the nozzle and jets. of air allowing efficient sorting.
- the outlet orifices of the nozzles 14, each orifice corresponding to a module 100 comprising several valves 12, are such that the arrangement of the jets is flat or, in other words, the air jets form a flat curtain.
- the extent over which the jets act from the orifices and in the direction of the jets, being from 5 to 50 mm, preferably from 10 to 35 mm, ie an extent of 25 mm. This allows the compactness of the device, while ensuring sufficient space to provide a number of jets, corresponding to the number of modules, adapting to the characteristics of the objects to be deflected.
- valves 12 within the modules 100 on either side of the conduit 18, and in particular of the conduit 182 are particularly advantageous for limiting the size of the device 10.
- FIG. 2 some of the valves 12 are shown. in the upper part of the modules 100 and part of the valves 12 in the lower part of the modules 100. As shown in Figures 1 and 2, three valves 12 are in the upper part and two valves are in the lower part of the modules 100.
- the modules 100 can be arranged in a fan shape with respect to the nozzles 14. In other words, the modules 100 are arranged in wedges of orange with respect to the nozzles 14. This is visible on the top of figure 2 where three valves 12 of each module 100 are aligned radially around the nozzles. This allows an identical arrangement of the modules 100 with respect to each nozzle 14 while ensuring the compactness of the device 10 in the housing 80. This makes it possible to guarantee exactly the same air flow channels for each nozzle, in particular in terms of length. , geometry and volume.
- the modules 100 can be of modular construction; one or more modules are used depending on the desired performance of the device 10 and the modules can be grouped. Modules 100 can be built in groups of several modules. This makes device 10 easier to manufacture.
- the modules 100 are identical from a "pneumatic" point of view in the sense that the valves 12 of the modules are connected in the same way to the outlet of the nozzles from one module to another. There is therefore the same response time for the formation of each air jet.
- the modular construction makes it possible to manufacture smaller parts and in greater numbers.
- the modular construction of the modules 100 can also be in groups of several modules 100, for example three modules 100 grouped together.
- Figure 3 illustrates a rear view of the device of Figure 2 in which the fan-shaped arrangement of the modules 100 is better visible.
- the valves 12 of each module 100 have an arrangement aligned according to radii converging towards nozzles (not visible).
- the modules 100 have three valves 12 in their upper part and two valves 12 in their lower part; the five valves 12 of each module 100 are arranged in fan-shaped planes around the nozzles 14.
- the valves 12 can be arranged on bars 22.
- the invention also relates to a system for sorting objects which comprises the pneumatic device 10.
- the objects to be sorted can be nominal objects (nominal sample diverted to the test station) or non-compliant objects (debris, capsules that are not or not fulfilled, etc.). Thanks to the combination of selective activation of the number of modules and the number of valves within each module, the air jets are adapted to the objects so as to sort the objects efficiently.
- Such a system can be used in the pharmaceutical industry to divert objects such as pharmaceutical tablets or capsules (capsules, empty or filled), from 20 mg to several grams.
- FIGS. 4 and 5 illustrate perspective views of the sorting system 30.
- the system comprises a chamber 32 for analyzing the characteristics of the objects to be sorted.
- the chamber 32 analyzes all the objects, the pneumatic device 10 being capable of deflecting the objects according to the characteristics analyzed in the analysis chamber 32.
- a control unit selectively activates all or part of the modules 100 and the valves 12 depending on the characteristics of the objects analyzed in the analysis chamber 32 .
- the objects can be accelerated to pass individually in the chamber 32 opposite a microwave sensor which allows the prediction of their mass and/or their humidity level, and which precedes the sorting device.
- This measurement chamber 32 also allows the quantification of the speed of the objects and their time of arrival at the sorting jets.
- Objects travel in single file, at high speed - between 5 m/s and 25 m/s.
- the objects leave the chamber 32 through the tube 36.
- the objects travel opposite the device 10 which operates the deflection of the objects according to criteria of non-compliance or other, detected in the chamber 32.
- the orifices of the nozzles 14 are aligned, along an axis transverse to the direction of scrolling of the objects. This makes it possible to effectively intercept objects.
- the air jets then form a plane, or curtain, transverse to the direction scrolling objects.
- a plurality of devices 10 can be used. For example, two (FIG. 4), three or even four devices 10 can be used, in order to better adapt to the sorting rates imposed by the scrolling speed of the objects.
- One of the devices 10 can be dedicated to the deviation of non-compliant objects and another device 10 dedicated to test sampling (possibly in addition to a systematic analysis in chamber 32).
- the devices 10 can be arranged around the direction of scrolling of the objects, for example one above the other, on either side of the scrolling of the objects.
- the system may include a channel 34 for guiding the objects leaving the chamber 32 in a running direction.
- the channel 34 makes it possible to convey the objects in line following an almost rectilinear trajectory. This makes it possible to present the objects one by one opposite the device 10, which facilitates their deflection.
- the channel has two flat surfaces 341 and 342 guiding the objects.
- the width of the channel 34 is adjustable transversely to the scrolling direction of the objects to be sorted.
- the width of the channel is adjustable in the direction of alignment of the nozzles 14.
- the space between the flat surfaces 341, 342 is adjusted to the width of the objects to be sorted.
- Channel 34 is adjustable so as to direct objects whose width varies between 3 mm and 25 mm depending on the format of the product to be sorted.
- the nozzles 14 direct one or more jets of air in the channel 34 towards the objects to be sorted according to the characteristics of the objects to be sorted.
- Figure 6 shows a schematic top view of the sorting system 30.
- Figure 6 shows how to adapt the air jets to the objects according to their width, by varying the number of modules activated - in addition to the fact that the intensity of each jet varies according to the combination of valves activated within each module.
- the objects are led into the channel 34, between the flat surfaces 341 and 342.
- the flat surfaces are brought closer together so that a single nozzle 14 directs the jet of air from the device 10 into the channel 34.
- a single module 100 is then activated.
- the flat surfaces are spaced apart so that two nozzles 14 direct the air jet from the device 10 into the channel 34.
- the flat surfaces are still far apart so that three nozzles 14 direct the jet of air from the device 10 into the channel 34.
- up to six nozzles 14 can dispense jets of air, corresponding to the activation of six modules 100.
- the width of the channel 34 is for example between 5 and 50 mm, preferably between 5 and 30 mm, preferably between 5 and 25 mm, to adapt well to the number of air jets.
- the device 10 and the sorting system 30 make it possible to generate a jet of variable width and intensity. Such variation makes the system 30 versatile, adaptable to objects of mass, size, geometry, speed, etc. variables.
- FIG. 7 shows a schematic view of the sorting system 30, in particular, with one or more sorting lanes 38, 40.
- the objects are guided by the channel 34 then pass opposite the nozzles of a or more devices 10.
- the objects to be deflected pass through the air jets 20 forming a curtain.
- the device or devices 10 divert the objects to one or other of the sorting lanes - according to the arrows 42, 44 - due to an inconclusive sampling test or compliance test.
- the unsorted objects continue their trajectory along the arrow 46. According to FIG.
- a device 10 can be placed above the scrolling of the objects to deflect them towards a lower track 40 and another device 10 can be placed below the scrolling of the objects to deflect them towards an upper track 38.
- Sorting can be in a horizontal plane.
- the distance between the exit of the chamber 32 and the position of the nozzles 14 is chosen so as to allow time for the object to leave the chamber 32 before being deviated if necessary. Otherwise, the object could already be subjected to a transverse force while it is still partially driven and guided by the tube 36, thus risking hindering the deflection of the object.
- the number of air jets and the intensity of each air jet produced respectively by a module 100 are variable according to an input instruction coming from the control unit.
- the setpoint determines the number of modules 100 activated and the combination of valves 12 activated within each module 100. The operation of each jet will therefore be proportional to this setpoint.
- This set point is calculated according to several characteristics analyzed in the chamber 32.
- the mass of the objects is taken into account, with a different combination of valves 12 being activated to increase or decrease the intensity of the jet.
- the speed of the objects is also taken into account as well as the moment at which the object will arrive at the height of the jets.
- the shape and volume of the objects influence the number and intensity of air jets activated as well as the width of the channel 34.
- the force to be applied to the object as well as the pressure present upstream of the valves are also taken into account so as not to damage the objects. This makes it possible to maintain the quality of the sorting even if the tanks are not able to recover their nominal pressure as quickly in cases where several openings close in time occur.
- the distance between the device 10 and the objects to be sorted is a factor to be taken into account to guarantee the performance of the sorting.
- the distance between the jet outlet (outlet orifices of the nozzles 14) and the axis of movement of the objects is between 10 and 40 mm, preferably between 15 and 30 mm, for example 20 mm. This makes it possible to present the objects to be deflected to the jet in an area where the deflection will be most effective while preserving the integrity of the objects to be deflected.
- the control unit comprises a PLC (for "Programmable Logic Controller” or programmable logic controller), an input/output card with very reactive digital outputs (including an on-board FPGA processor - for "field-programmable gate array” or network of programmable gates), and a power control card (equipped with FPGA controllers and MOSFETs - for Metal Oxide Semiconductor Field Effect Transistor).
- PLC for "Programmable Logic Controller” or programmable logic controller
- an input/output card with very reactive digital outputs including an on-board FPGA processor - for "field-programmable gate array” or network of programmable gates
- a power control card equipped with FPGA controllers and MOSFETs - for Metal Oxide Semiconductor Field Effect Transistor.
- the sequence for establishing an air jet occurs as follows.
- the PLC controls the opening of the valves 12.
- the digital output which activates the valve(s) 12 is energized.
- the lapse of time from the command depends on the architecture of the control system implemented (PLC programming and cycle times, communications between the PLC and the digital output card, type of digital output card, ). This time period can reach 1 millisecond.
- the current is established in the actuating coil of the respective valves, until reaching a sufficient force to start moving the moving parts of the valves (up to a few milliseconds); depending on the valve combination, the controlled valves open and air begins to flow.
- the air will take some time to come out of the nozzle holes.
- the jet is established.
- the lapse of time between the activation signal and the moment when the jets are fully established is less than 5 ms, preferably less than 4 ms, preferably less than 3 ms, preferably less than 2 ms.
- the objects are deflected from their substantially rectilinear course towards the sorting lane or lanes 38, 40. Thanks to the sorting lanes 38, 40, to the device 10 and to the adaptation of the number and the intensity of the air jets, the deflected objects are not damaged. These objects can be the subject of a new conformity check in which a device 10 can again be implemented; the objects can be returned to the main circuit as they have not been damaged.
