Definitions
- the field of the invention is that of sorting mail items in bins in postal sorting centers.
- the invention more particularly relates to a sorting installation comprising sorting outlets aligned along a sorting conveyor each provided with a housing for a bin in which sorted mail items are stored and also comprising a conveyor of bins which extends in a certain conveying direction under said sorting outlets for transporting trays filled with mail items sorted from the sorting outlets to a feed inlet of the sorting conveyor.
- a sorting installation of this type is for example described in WO-A-Ol / 12348.
- the arrangement of the sorting outlets above the conveyor of bins and the orientation of the bins in the housing require the Operators to extract the bins at arm's length and turn them by 90 ° before laying them oriented in the length on the conveyor of bins.
- the object of the invention is therefore to remedy the aforementioned problems.
- the invention relates to a sorting installation comprising sorting outlets aligned along a sorting conveyor each provided with a housing for a tray in which sorted mail items are stored, a conveyor of bins which extends in a certain conveying direction under said sorting outlets for transporting bins filled with mail items sorted from the sorting outlets to a feed inlet of the sorting conveyor, characterized in that it comprises in addition, a shuttle robot able to roll on the ground autonomously along the sorting outlets, said robot comprising handling means capable of extracting a tray from a housing of a sorting outlet and placing it on the conveyor of bins, said handling means comprising a toboggan having a low end which is slidably coupled to said ferry conveyor, said handling means being arranged to release in the upper part of the slide the extra tray it of its housing so that the tray slides down to the bottom of the slide by the effect of gravity, and in that the handling means comprises a motorized roller roller which is arranged between the lower part of the toboggan and the tray conveyor,
- the idea the basis of the invention consists automate the step of extracting and injecting bins on the bins conveyor from the sorting outlets.
- the idea is to use a toboggan to move by gravity a tray from a sorting outlet to the tray conveyor and to impose a 90 ° rotation to the tray at the output of the slide to orient it in the length on the conveyor of bins.
- the rotation movement of the tray is here carried out via a simultaneous drive by the roller and the tray conveyor in two directions which are perpendicular to each other.
- the sorting equipment according to the invention may also have the following particularities:
- the speed of movement of the tray induced by the roller is less than the movement speed of the tray induced by the tray conveyor;
- the motorized roller is designed to operate in reverse when the rotation of the tray is less than 90 °;
- the shuttle robot comprises a fixed flat roller disposed between the motorized roller and the tray conveyor to rotate the tray during its rotational movement;
- the shuttle robot comprises a retractable flat roller adapted to be deployed on the tray conveyor to rotate the tray during its rotational movement.
- the motorization of the roller to Roller here makes it possible to control the insertion speed of the tray on the tray conveyor so that the speed of movement of the tray on the roller is constantly lower than the speed of movement of the tray on the tray conveyor.
- the arrangement of the roller of the motorized roller in the extension of the median of the slide also allows to create a central support point under the tray while the tray is in contact with the toboggan or ferry conveyor by two points of support.
- the point of contact between the tray and roller makes it possible to balance the tray on the roller to facilitate its rotation of 90 ° at the output of the slide.
- FIG. 1 is a schematic representation of the top of a sorting installation according to the invention
- FIG. 2 diagrammatically shows in profile a shuttle robot in front of a sorting outlet of the sorting installation according to the invention
- FIG. 3 diagrammatically shows a portion of the shuttle robot of the sorting installation according to the invention.
- FIG. 1 shows a sorting installation 1 according to the invention which comprises sorting outlets 2 aligned along a sorting conveyor 3 each with a housing 4 for a tray 5 in which sorted mail items 6 are stored.
- FIG. 1 also shows a feed inlet 7 designed to put mail items 6 in series on the sorting conveyor 6 according to the conveying direction F1, and then sorted in the corresponding sorting outlets 2.
- a conveyor 8 of bins is also provided under the sorting outlets 2 for conveying the bins 5 loaded mail items 6 from the sorting outlets 2 to the feed inlet 7 in a conveying direction F2.
- the shuttle robot 9 slidably engages a guide rail 10 which extends in front of the conveyor 8 of trays over its entire length, as shown in Figures 1 to 3.
- the shuttle robot 9 comprises a frame 11, here L-shaped with a plate 11a with wheels and a backrest 11b, on which is mounted a handling means 12 able to extract a container from a housing a sorting outlet and place it on the bins conveyor.
- the handling means 12 comprises a motorized gripping head 13 comprising two horizontal parallel bars, telescopic and vertically movable for extracting a tray 5 from the housing 4 of a sorting outlet 2.
- the handling means also comprises a slide 14 for tray 5 which extends under the telescopic head 13 so that the telescopic gripping head 13 descends vertically to deposit the tray on the slide.
- the slope of the slide 14 is thus chosen so that the bins 5 slide by gravity to the conveyor 8 of bins.
- the slide 14 may also consist of an alignment of rollers or rollers 15 mounted free in rotation in order to facilitate the sliding of the trays 5 and tolerate slower slope inclinations of the slide.
- FIG. 3 shows the shuttle robot 9 according to the invention without the gripping head 13 and where the lower end of its slide is provided with a motorized roller 16 with a roller 17 which comes to be interposed between the bottom end of the slide 14 and the rail 10 of the conveyor 8 of bins.
- the roller 17 is here oriented perpendicular to the conveyor 8 so as to move the tray 5 in a transverse direction F4 to the conveying direction F2, as shown in Figure 3.
- the diameter of the roller 17 is here greater than that of the motorized roller 16, for example of the order of 1.5 to 2 times greater, so that the tray 5 moving on the roller 17 does not come into contact with the motorized roller. 16.
- the tanks 5 having a bottom deformed by the distribution of their load forward or backward, for example a curved bottom or a twisted bottom, can all be moved by the roller 17.
- the roller 17 also has a width less than the width of the tray 5 so that the tray 5 is in contact with the roller 17 on a single point of support.
- the roller will always have a lower bearing surface to the support surface of the tray on the slide 15 or on the conveyor 8 of trays 5.
- the roller 17 is also arranged in the extension of the median line M1 of the slide so that the slide 5 of the slide 14 is centered and in equilibrium on the roller 17.
- the tray 5 will initially have two points of support with the slide 14 and a central point of support with the roller 17, then, once in contact with the ferry conveyor, the tray 5 will have two points of support with the conveyor 8 of bins and a central point of support with the roller 17.
- the single point of support with the roller 17 will move under the tray 5 to put the tray unbalanced on the roller 17 and promote the pivoting of the tray 5 to it rotates 90 ° in the direction of rotation of the arrow RI.
- the speed of movement of the tray 5 induced by the roller 17 must be less than the speed of movement of the tray 5 induced by the conveyor 8 of bins.
- a control / command unit 18 is installed on the shuttle robot 9 to control the speed of rotation of the roller
- a cell 19, shown in FIGS. 1 to 3, able to detect the positioning of a tray at the outlet of slide 19 is also installed on the conveyor 8 under each sorting outlet 2.
- the cells 19 are here designed to produce bin positioning data and transmit them to the control unit via wireless communication represented by the dotted arrow DI.
- control unit / control 18 drives the motorized roller 16 backwards for a few seconds, for example between 3 and 5 seconds, to move the ferry back to the toboggan.
- This movement back and forth from the tray on the roller 17 is repeated as many times as necessary to ensure a complete rotational movement of 90 ° tray.
- the shuttle robot 9 also comprises a fixed flat roller 20 disposed between the motorized roller 16 and the conveyor 8 of bins and a retractable flat roller 21 adapted to be deployed on the conveyor 8 of trays.
- rollers are here designed to rotate the tray 5 during its rotational movement and prevent rotation of the tray beyond 90 °.
- the retractable roller 21 is deployed on the conveyor 8 downstream of the fixed roller 20 which itself is downstream of the roller 17 of the motorized roller 16 with respect to the conveying direction F2.
- control / control unit 18 controls the retraction of the retractable roller 21 out of the conveyor 8 of bins so as not to interfere with the conveying of the bins on the conveyor of bins coming from the upstream of the conveyor 8 in said inverted conveying direction.
- the toboggan may be provided with a fixed roller and a retractable roller at the downstream and upstream ends of the motorized roller with respect to the conveying direction, so that the rotation aid is effective in both directions of conveyor of bins.
- shuttle robots 9 may be used along the conveyor 8 of bins to accelerate the rate of extraction and injection trays 5 on the tray conveyor.
