Definitions
- the invention relates to the field of sorting objects and more particularly concerns a device for conveying and separating objects.
- the invention also relates to an object sorting installation comprising such an object conveying and separation device.
- object sorting installations such as parcel sorting installations comprising a high-speed sorting conveyor designed to sort parcels according to a certain sorting indication and parcel input lines designed to receive parcels in bulk, serialize said parcels and then space them apart from each other in accordance with determined pitches before inserting them onto the sorting conveyor.
- each input line is equipped with a conveying and separation device, also called a “centering module”, such as that described in patent application US2022112034.
- Conveying and separating devices typically include a series of independently powered, variable speed conveyor sections that are accelerated or slowed down to position packages in their path.
- This “unbalance” effect is particularly significant in packages that are heterogeneous in size, material, shape or density, such as International Small Packets (ISP).
- ISP International Small Packets
- the aim of the invention is therefore to solve the aforementioned problems.
- the invention relates to a device for conveying and separating objects
- a device for conveying and separating objects comprising a conveyor designed to convey said objects in a certain conveying direction, said conveyor comprising a succession of independently motorized conveying sections distributed one after the other in the conveying direction, sensors designed to generate digital data representative of the detection of the presence or absence of an object transported on each conveying section, and a central unit configured to control the speed of the conveying sections independently of each other as a function of said digital data representative of the detection of the presence or absence of an object transported, the central unit being configured to constantly maintain at iso-speed at least two adjacent conveying sections transporting the same object, characterized in that the central unit is configured to control said speed of the conveying sections so that the objects are distributed on the conveyor in predetermined steps (PP) on said conveyor and in that the central unit is set to calculate an offset of an object relative to the center of the step in which it is to be positioned and to control in return the acceleration or deceleration of the conveying sections in the conveying direction to center the
- the idea behind the invention is to force objects to cross conveyor sections at the same speed to reduce the risk of objects shifting or pivoting.
- the device for conveying and separating objects according to the invention may also have the following particular features:
- the offset is a physical offset
- the central unit is configured to identify at least one conveying section not transporting an object downstream in the conveying direction relative to a conveying section transporting an object upstream in the conveying direction and at a certain conveying speed, and to control in return the acceleration or deceleration of said at least one conveying section downstream up to said certain conveying speed of the upstream conveying section;
- the central unit is configured to calculate a certain useful length of the conveyor corresponding to the cumulative length of all the conveying sections of the conveyor to which is added a length corresponding to a predetermined percentage of the total length of an object to be conveyed, then to command the stopping of the acceleration or deceleration of the most downstream conveying section of the conveyor at the latest when said length corresponding to said certain predetermined percentage of the length of the object has left the downstream conveying section;
- the central unit is configured to control the drive of the conveyor sections transporting the same object by imposing a maximum speed level and a minimum speed level, the central unit being configured to modulate the duration of maintenance of at least one of the maximum or minimum speed levels according to the cumulative length of the conveyor sections and the length of the object;
- the central unit is configured to control the acceleration or deceleration of the conveyor sections transporting the same object by imposing a speed level of minimum amplitude and maximum duration;
- each conveying section extends along a certain first length L1 in the conveying direction and along a certain second length L2 transversely to the conveying direction, said first length being less than the second length;
- each conveyor section comprises a conveyor belt equipped with a rod and a sliding base for the belt comprising guides for the rods;
- the conveyor comprises an inter-junction blade arranged between each belt
- each downstream conveyor section extends below an upstream conveyor section.
- the invention also extends to an object sorting installation comprising a sorting conveyor designed to convey and sort the objects into sorting outlets according to a certain sorting indication and an input line designed to supply the sorting conveyor with objects, said input line comprising an object conveying and separation device according to any one of the preceding claims.
- the sorting installation 1 of objects 2 according to the invention shown in the is particularly well suited to equipping a postal sorting center or a logistics platform.
- objects 2 we mean all types of objects such as parcels or packages, for example PPIs (for "Small International Packets”) but also letters or any other object that can be processed in postal or logistics sorting facilities.
- PPIs for "Small International Packets”
- letters or any other object that can be processed in postal or logistics sorting facilities for example
- the sorting installation 1 for objects 2 typically comprises a sorting conveyor 3 designed to convey and sort the objects 2 into sorting outlets 4 according to a certain sorting indication affixed to each object 2 and an input line 5 designed to supply the sorting conveyor 3 with objects 2.
- the input line 5 will here comprise a conveying and separation device 6 according to the invention also called a “centering module” designed to convey the objects in a certain conveying direction D1 in predetermined steps PP.
- the conveying and separating device 6 typically comprises a conveyor 7 designed to convey said objects in the conveying direction D1, formed of a plurality of conveying sections 8 independently motorized and distributed one after the other in the conveying direction D1.
- the conveyor 7 will also comprise a plurality of sensors 9, here for example optical sensors, designed to generate digital data representative of the detection of the presence or absence of an object 2 transported on each conveying section 8.
- the conveying and separation device 6 will also comprise a central unit 10 configured to control the speed of the conveying sections 8 independently of each other as a function of said digital data representative of the detection of the presence or absence of the transported object 2, so as to distribute the objects on the conveyor 7 in the predetermined steps PP.
- predetermined steps PP is meant predetermined conveying locations on the conveyor 7 in the conveying direction D1 designed to each convey one object on the conveyor 7. Each predetermined conveying location extends a certain length in the conveying direction D1.
- Inserting an object into its step guarantees proper injection of the object onto the sorting conveyor 3, reliable detection of certain data such as weight and destination address, and a reduction in the risk of collision between objects 2 that follow one another.
- the predetermined steps according to the invention therefore follow one another in the conveying direction so that the objects are conveyed in series in the conveying direction, each in a predetermined step PP.
- the predetermined steps PP can have a physical or spatial step that fluctuates, i.e. a variation in the length of the conveying location in the conveying direction, during the conveying of the objects 2 on the conveying sections 8 in response to the change in speed of the conveying sections 8, the predetermined steps PP will always have a constant time step.
- each object 2 is at one time or another during its transport on the conveyor 7, straddling several conveyor sections 8.
- Another function of the central unit 10 is to constantly maintain at iso-speed at least two adjacent conveyor sections 8 transporting the same object 8.
- the central unit 10 will be able to constantly maintain at the same speed all of the conveyor sections 8 transporting the same object 2.
- the central unit 10 may also be configured to identify at least one conveying section 8 not transporting an object 2 downstream in the conveying direction D1 relative to a conveying section transporting an object upstream relative to the conveying direction D1 and according to a certain conveying speed.
- the central unit is then configured to control the acceleration or deceleration of said at least one downstream conveying section 8 to said certain conveying speed of the upstream conveying section 8.
- This setting allows the conveyor sections 8 to be accelerated or slowed down as quickly as possible to the desired speed when they are not transporting objects 2.
- the central unit 10 may also be configured to, from the digital data representative of the detection of the presence or absence of an object 2 on a conveying section 8, calculate an offset of the object 2 inserted on the conveyor 7 relative to the center of the predetermined pitch PP in which it must be positioned and to control in return the acceleration or deceleration of the conveying sections 8 in the conveying direction D1 to center the object 2 in its pitch.
- the offset of the object 2 inserted on the conveyor 7 relative to the center of the predetermined step PP in which it must be positioned may be a time offset or a spatial offset. All the specificities described below relating to the time offset apply to a spatial offset of the object. Thus, if the calculation of a time offset requires the use of data representative of a time step to be imposed on the objects 2, the calculation of a spatial offset requires the use of data representative of a spatial step to be imposed on the objects 2.
- the central unit 10 will include in memory data representing respectively the time step or the spatial step to be imposed on the objects 2 on the conveying and separation device 6 according to the invention.
- the time step or the spatial step may vary depending on the type of objects to be conveyed.
- the idea here is to center each object 2 in its step so as to optimize weighing, detection of the sorting indication and injection onto the sorting conveyor 3.
- the central unit 10 can be configured to vary the speed of the conveyor sections 8 by following correction cycles.
- the acceleration and deceleration amplitude of the conveyor sections 8 may in particular be set to the maximum tolerable value without risk of slipping of the objects 2 (here for example 5 m/s2).
- the central unit 10 may be configured to command the start of a correction cycle only when the object 2 has completely entered the conveying and separation device 6 and to command the stopping of the correction cycle at the latest when a certain percentage of the length L of the object 2 has left it.
- the crossing time of the conveying and separation device 6 must be: T0 – Dt.
- T0 being the reference duration and corresponding to the travel time of the conveying and separation device 6 from end to end by an object 2 of any length, centered in its pitch on arrival and which therefore must not be corrected.
- a first correction cycle consists of controlling the drive of the conveyor sections 8 transporting the same object 2 by imposing a ceiling speed level and a floor speed level.
- the central unit 10 is then configured to modulate the duration of maintenance of at least one of the ceiling or floor speed levels as a function of the cumulative length of the conveying sections 8, the length of the object and the desired correction.
- ceiling speed thresholds V+ and floor speed thresholds V- will be chosen between the minimum landing speed Vmin and the maximum landing speed Vmax to best cover the targeted correction range (determined according to the length of the conveyor 7 and the length range of the objects 2).
- Vm retained For a strong correction of a delay or an advance of an object 2 in relation to its step, the speed level Vm retained will be V+ (or V-), here V- on the .
- the speed level Vm retained will be less than V+ or greater than V-, here greater than V- on the .
- the cycle can be limited to going from its input speed Ve on conveyor 7 to its output speed Vs from conveyor 7 at the right time.
- the speed level Vm will therefore be Ve, as visible on the . This avoids shaking an object unnecessarily by applying a double speed variation to it.
- a second correction cycle consists of controlling the acceleration or deceleration of the conveyor sections 8 transporting the same object 2 by imposing a speed level of minimum amplitude and maximum duration.
- This correction cycle consists of applying a speed level Vm which is maintained throughout the crossing of the conveying and separation device 6.
- the speed level Vm retained will be lower than V+ or higher than V-, here higher than V- on the and maintained as long as possible before the object is accelerated to the exit speed Vs.
- the purpose of the second correction cycle is to minimize the duration of the acceleration and deceleration phases which risk destabilizing the objects 2.
- the strong correction of a delay via the first correction cycle requires a plateau speed of 0.6 m/s while via the second correction cycle only 0.98 m/s is necessary, as visible on the .
- the dotted arrow here represents the gap E between object 2A and object 2B.
- the central unit 10 may also be configured to prioritize a correction of the object furthest downstream on the conveyor 7 in the conveying direction D1 to the object furthest upstream on the conveyor 7.
- the conveyor sections 8A, 8B and 8C first align with the correction cycle of the most downstream object 2, then with the one following it upstream in the conveying direction D1 by adapting the conveying speed of each conveyor section 8 to the conveying speed determined for the following object 2 as soon as it is released from the first object 2.
- the central unit 10 may also be configured to optimize the correction cycles by considering a “useful” length of the conveyor 7 greater than the actual length of the conveyor 7 and corresponding to the cumulative length of all the conveying sections 8 of the conveyor 7 to which is added a length corresponding to a certain percentage of the total length of an object 2 being conveyed on the conveyor 7.
- This function here makes it possible to take advantage of the heterogeneity of the weight distribution of object 2, generally greater towards the center of object 2 and less significant towards the edges, in order to continue the correction cycle of object 2 even if object 2 straddles conveyor 7 and an output conveyor CS downstream of conveyor 7.
- the mass at the front of the object 2 is considered here as an example to be negligible compared to the central mass of the object 2, which makes it possible to maintain a certain change in speed between the last conveying section 8 of the conveyor 7 furthest downstream in the conveying direction and the outlet conveyor CS without risking rotating the object 2.
- the central unit 10 includes in memory at least a certain percentage of the length of a type of objects corresponding to a negligible mass compared to the rest of the length of the object 2, for example 20% of the length of the object 2 within the framework of the PPIs.
- the central unit 10 will be configured to recover length data of the object 2, for example from data representative of the detection of the presence of an object 2 transported on the conveying section 8 furthest upstream in the conveying direction or by a detection process upstream of the conveying and separation device 6, then to control in return the maintenance of the correction cycle over the entire “useful” length of the conveyor 7.
- a third correction cycle may aim to avoid its overflowing from the predetermined step PP without seeking to center it as best as possible in its step so as to favor the correction of the following object 2 by maximizing the capacity of the conveying and separation device 6 to process it without risk of speed conflict.
- the correction cycles can be recalculated during the journey of object 2 on the conveying and separation device 6 (for example at the exit of the first three conveying sections 8) taking into account the actual position of object 2 in relation to its theoretical position.
- each conveying section 8 extends along a certain first length L1 in the conveying direction D1 and along a certain second length L2 transversely to the conveying direction D1, said first length L1 being less than the second length L2.
- the conveyor sections 8 are therefore wider than they are long.
- conveyor sections 8 can be arranged one after the other, which allows control adapted to a large heterogeneity of objects 2, in length, weight and density.
- each conveying section 8 may comprise a transport belt 11 equipped with a retaining ring 12 and a sliding sole 13 for the belt 11 comprising a guide 13A for the retaining rings, here for example a guide groove.
- each belt 11 is mounted on a downstream idler roller 14A and an upstream idler roller 14B in the conveying direction D1 and that each conveying section 8 includes a device 15 for adjusting the parallelism of its belt 11.
- the parallelism adjustment device 15 is designed to maintain the eccentric located on the downstream idler roller 14A in the conveying direction D1, also called the output roller.
- the parallelism adjustment device 15 here makes it possible to limit the forces on the ring 12 and therefore to reduce the risks of breakage but also to avoid the appearance of a bump on the top of the belt 11 when the ring 12 rests a little too much on its guide 13A.
- the parallelism adjustment device 15 will comprise for example an eccentric with an axis integrated on bearings accepting this potential offset.
- the conveying sections 8 can have a first length L1 as small as possible, here of the order of 175mm and a second length L2 equivalent to the width of the conveyor 7, here of the order of 550mm.
- the conveyor 7 of the conveying and separation device 6 may also comprise an inter-junction blade 16, visible in FIGS. 8, 9 and 10, arranged between each belt 11 and more specifically between the idle roller 14A downstream of an upstream conveying section 8 and an idle roller 14B upstream of a downstream conveying section 8 in the conveying direction D1.
- the inter-junction blades 16 will therefore be arranged so as to be as close as possible to the conveying sections 8, so as to reduce the space between two adjacent conveying sections 8.
- the inter-junction blades 16 make it possible on the one hand to avoid jamming of objects 2 between two adjacent belts 11 and on the other hand to minimize the jolting of the objects 2 when crossing the conveyor sections 8 by minimizing the amplitude and duration of the instability of the objects 2 during the transitions.
- the inter-junction blades 16 may be inclined substantially upwards in the conveying direction D1 so as to achieve the transitions as smoothly as possible.
- the conveyor sections 8 may also be distributed in a staircase fashion in the conveyor direction D1, such that each downstream conveyor section 8 extends below an upstream conveyor section 8, in order to improve the transitions of object 2 from one conveyor section 8 to another.
