Definitions

• the field of the invention is that of the processing of mail items in a postal or logistics sorting center.
• the invention relates more particularly to a device for supplying an unstacking magazine with mail items.
• Document FR 2 663 915 discloses a device specifically designed to supply a destacking store with mail pieces on edge from mail items ordered and stacked flat in bins, generally large format mail items.
• This device comprises a feed conveyor which transports in sequence the bins crosswise in a certain conveying direction to the unstacking magazine.
• An automated tray tipping system is also provided at a downstream end of the conveyor for pivoting the trays one by one forward in the conveying direction on the unstacking magazine.
• the pile of mail items stored flat in the bin is thus tilted forward so that mail items are singing in the bin.
• the tilting system is also arranged to incline the tray sufficiently on the unstacking magazine to allow the stack of mail items on the edge of the tray to slide on the unstacking magazine.
• the mail items are thus advantageously oriented on edge and ordered in sequence on the unstacking magazine to be moved by an operator using a pallet until the unstacker.
• This feeding device is however not suitable for processing mail items stored on edge in bins.
• the trays loaded with mail pieces on edge are generally oriented lengthwise on the conveyor prohibiting support by means of tilting tray crosswise.
• the object of the invention is therefore to solve the aforementioned problems by proposing an improved feed device capable of feeding a stacking magazine with mail items stored flat. and on edge in an ergonomically optimized work space for an operator while minimizing the floor area of the device.
• the subject of the invention is a device for feeding an unstacking magazine with articles of mail on edge
• a first feed conveyor which extends in a certain conveying direction to said unstacking magazine for conveying cross-sided bins loaded with mail items laid flat in the bottom of the bins and a tray tilting means interposed between said first feed conveyor and the magazine adapted to pivot on the front a tray in said conveying direction on a ramp of the tilting means so as to bring the mail items on edge from the tray on the unstacking magazine
• it further comprises a second supply conveyor which extends parallel to the first conveyor according to said conveying direction up to said unstacking shop for conveying bins oriented lengthwise loaded with mail items deposited on edge in the bottom of trays and a tray overturning means interposed between said second feed conveyor and said unstacking magazine adapted to fold a tray on the side transverse to said conveying direction on the unstacking magazine so as to bring the mail items onto singing from the tray on the unstacking magazine
• the idea underlying the invention is to supply a desilage store in mail items singing from mail items stacked flat or edge in trays conveyed on two separate conveyors.
• the invention consists in causing the two conveyors to converge at the tipping and tray overturning means in order to create a pile-up area of mail pieces on edge on the unstacking magazine.
• each stack of mail items is tilted from the front or side, depending on its orientation flat or on edge in the bins, to be oriented on singing in sequence on the pile reconstruction area of mail items .
• the operator is thus placed in front of the stack reconstruction zone to recover the pile of mail items on edge coming from the tilting or overturning means.
• the overturning means also makes it possible to process landscape and portrait oriented mail items, also known as mixed mail items.
• the device according to the invention may have the following particularities:
• the second tilting means comprises a stop at the bottom of the ramp designed to block the foot of a tray and leverage to set a tray on said unstacking store.
• FIG. 1 is a schematic representation in perspective of the device for feeding an unstacking magazine according to the invention:
• FIGS. 2 and 3 are diagrammatic representations in perspective of the device for feeding an unstacking magazine according to the invention with mailpieces stacked flat in bins on the first conveyor;
• FIG. 4 is a schematic perspective view of the device for feeding an unstacking magazine according to the invention with mail items stacked on edge in bins on the second conveyor;
• the device 1 according to the invention as shown in Figure 1 is particularly suitable for supplying an unstacking store 2 in mail items 3 of a postal sorting center or logistics.
• Stacking shop 2 is a temporary storage magazine for mail items that feeds an unstacker.
• the mail items 3 that feed the unstacking shop are usually letters, parcels, packages, etc.
• the device 1 comprises first and second feed conveyors 4, 5 designed to convey bins 6 loaded with mail items 3 in a certain conveying direction F1 to the unstacking magazine 2.
• the two conveyors 4, 5 converge at a downstream end 7 of the unstacking magazine 2 in order to concentrate the supply of mail items 3 on the stacking magazine 2 at a stack reconstruction zone ZI in mail items bounded in dotted line in FIG.
• the stack reconstruction zone ZI is advantageously located near a working zone Z2 of the Operator.
• the first and second conveyors 4, 5 are also terminated respectively by a tipping means 8 of the tray 6 and a tipping means 9 of the tray 6.
• Each means 8, 9 is respectively adapted to switch a tray loaded with mail items 3 oriented flat 3A, shown in Figures 2 and 3, and oriented on edge 3B, shown in Figure 4.
• the tilting means 8 is adapted to pivot a tray 6 on the front in the conveying direction Fl on a ramp 10 of the tilting means.
• the mail items 3 stored flat in the tray 6 are thus tilted and inclined edge in the tray to be discharged by sliding to the unstacking magazine 2, as shown in Figures 2 and 3.
• the ramp 10 of the tilting means is here curved to naturally slow the sliding of mail items 3 on edge.
• the overturning means 9 is designed to lay a tray 6 transversely to the conveying direction Fl on the unstacking magazine 2.
• the mail items 3 stored on edge in the tray 6 are thus slanted on edge on another slice and slide from the tray 6 on the unstacking magazine 2, as shown in Figure 4.
• the mail items stored flat in the bins are conveyed on the first conveyor 4 to be tilted by the tilting means 8 while the mail pieces 3 on edge in the bins are conveyed on the second conveyor 5 to be tilted by means of overturning 9.
• the tilting means 8 is automated so that each tray 6 arriving at the downstream end of the first feed conveyor 4 is automatically switched to the unstacking magazine 2 in an unloading position.
• the tilting means 8 comprises a hoop 11 rectangular designed to hook the top edges 12 of a tray 6 and rotate it by one of these edges facing the unstacking shop.
• the rotated tray 6 remains in the unloading position, as shown in Figure 3, according to a predefined time to allow the operator to retrieve the stack of mail items 3 which slips on edge on the unstacking magazine 2.
• the empty tray 6 is automatically rotated in the opposite direction to be evacuated on a discharge conveyor 13 of the device according to the invention.
• the tray evacuation conveyor 13, shown in FIGS. 1 to 4 extends here along the first conveyor 4, 5 to facilitate the evacuation of the empty trays 6 of mail items 3 from the warehouse. unstacking 2 to a storage area of the trays Z3, shown in dotted line in FIG.
• a new tray 6 loaded with mail items 3 then arrives at the end of the first conveyor 4 to be rotated in turn and so on.
• the pitch between each tray 6 on the first conveyor 4 is thus determined as a function of the conveying speed and the tilting time in the unloading position.
• the overturning means 9 comprises a ramp 14 which extends transversely with respect to the conveying direction F1 and which goes down from the second feed conveyor 5 to the unstacking magazine 2.
• This ramp 14 makes it possible to tilt and slide a tray 6 transversely with respect to the direction of Fl.
• the second tilting means 9 further comprises a stop 15 at the bottom of the ramp 14 designed to block the foot of a tray 6 in transverse displacement on the ramp 14.
• the coated tray 6 remains in abutment on the abutment 15 so as to maintain an inclined position of the tray on the unstacking magazine 2 to facilitate the unloading of mail items 3 on edge.
• the empty tray 6 is then recovered by the operator to be placed on the conveyor 13 for evacuation of the tray.
• the ramps 10 and 14 are also intersecting with each other and are disposed on two adjacent sides of the mail rectification pile stacking zone ZI on said unstacking magazine.
• This arrangement of the ramps improves the working ergonomics of the operator.
