• the most favorable connection of machine 102 to 100 takes the shipments from the buffer of machine 102 just before the two loading areas of the buffer and from the buffer memory of machine 102 just before the loading area of the buffer memory and gives them in the buffer memory of machine 100 shortly before the loading area of the buffer again.
• connection conveyor device allows a functionally comparable logistical linking additionally from machine 100 to machine 102.
• FIG. 18 illustrates a further aspect of the system illustrated in FIG.
• FIG. 18 shows a schematic representation of an embodiment of a
• the device shown has a station in which the unaddressed broadcasts are generally supplied as a stack manually or by a loading device to the individual conveyor elements of the output conveyor 7.
• a number of dispensers are arranged along the same, into which the unaddressed transmissions are transferred.
• the consignments can be pre-sorted to 40 postmen with this exit conveyor.
• the individual dispensing stations can each be connected via a further active or passive transport system (eg conveyor belt or chute), which is arranged at right angles to the output conveyor 7, with corresponding containers for receiving the stacks or an area by correspondingly processing and packing these stacks for automatic separation become.
• a further active or passive transport system eg conveyor belt or chute
• the transfer to the delivery location takes place either almost vertically or almost horizontally. Depending on the version, the transfer can be carried out ballistically.
• the unaddressed mailing stacks on the output conveyor 7 can be transferred horizontally into the respective delivery point by a mechanism controlled by a control device or they are transferred vertically into an underlying delivery point. If the consignment stacks are located on individual trays or trays, the control device rotates, for example, in each case a carrier so that the consignment stack slips counter to the direction of movement of the carrier when it is above the desired dispensing point.
• each type of commercial is assigned to a postman, i. each postman is e.g. a large number of advertising mail from major customer A and a large number of advertising mail from major customer B were allotted.
• the function of processing unaddressed transmissions shown in FIG. 21 can be used in a device having one output (FIG. 2-FIG. 7) or two outputs (FIG. 8). It is understood that in a two-output structure, the unaddressed broadcasts can also be arranged at a higher throughput or for more output points.
• the tray is tilted and the material slip by gravity from the tray into a target location.
• the goods to be sorted can be fed to the tilting tray individually or as a stack.
• shipment batches are collected on a tray conveyor and then fed to an extraction unit.
• the shells are inclined in the conveying direction, so that an optimal stacking pattern (orientation along the bound side of the mailings) results when dropped from a Taschesorter.
• tilt trays are unsuitable. Tilting shells would lead to significant deterioration of the stacking image due to the undefined sliding action.
• the transport shells have a connecting edge (bound edge of the items) for the defined orientation of the items;
• the transport trays have depressions or are designed as a fork;
• the carrier car of the shells moves during unloading along a curved downward circular path and with rotation of the shells, so that fork-shaped narrow conveyor belt can drive under the stack of mail and take over the stack of mail continuously;
• the acquiring transport belts are designed as a section conveyor and lead the consignment stack to a packaging unit.
• the main advantage of the present solution is the continuous, jerk-free and guided transfer of mailings and mailing stacks from one tray conveyor to another at high speed.
