- the detection steps 219 and extraction and stacking of spacers 220 are therefore performed upstream of the first sorting outlet 205-1 and downstream of the last sorting outlet 205-n and in particular downstream of the confluence point 207.
- the detection step 219 is substantially similar to the detection step 122, and performed using the detection means 208.
- the step of extracting and stacking tabs 210 is substantially similar to the extraction step and interlayer stacking es 120.
- FIG. 5 describes the steps of the sorting method during the second sorting pass and the subsequent sorting passes of the sorting machine 201.
- a recycling step 221 the batteries are recovered sorting outlets 205 to reintroduce the input of the first unstacker 202, as previously described.
- the recycling step 221 is thus substantially similar to the recycling step 1 19.
- a destacking step of postal and intermediate items 222 is carried out by means of the first unstacker 202.
- the postal items 1 and the intermediate items 2 are automatically depilated with a gap separating them for example substantially constant.
- the step of unstacking mail items and tabs 222 is substantially similar to the step of unstacking postal items and tabs 120.
- step of transporting postal and intermediate items 223 postal items 1 and tabs 2 are automatically transported, one behind the other, to the sorting outlets 205.
- This step of transporting postal and intermediate items 223 is substantially similar to stage of transport of postal and intercalary items 121.
- Upstream of the first sorting outlet 205-1, during a step of introduction of postal items 224 optional, is automatically introduced in the stream of mail items 1 and 2 pasted dividers, postal items 1 from the loop of the conveyor 304 by the second half turn 204-4. This optional step is shown in dashed lines in FIG. 5.
- a determination step 225 substantially similar to the determining step 125 is performed and, depending on the determination, a step of transport of postal items 226, a step of distributing and stacking postal items 227, an unstacking step and inserting tabs 228, a step of transporting postal and intermediate items 229, a dispensing and stacking step of postal and intercalary shipments 230 substantially similar respectively to the step of transporting mail items 126, the dispatching and stacking step of postal items 127, the unstacking step and introduction of inserts 128, the transport step of postal and intermediate items 129, and the step of distributing and stacking postal and intermediate items 130.
- a detection step 231 is carried out similar to the detection step 122. According to the detection, a detection step is performed. extraction and stacking step of tabs 232 substantially similar to the step of extraction and stacking of tabs 123. Then, a step of transporting postal items 233 is carried out similar to the step of transporting mail items 124.
- the passage of the postal items 1 and the introduction of the dividers 2 are synchronized, in particular at the entry level.
- the speed of the first unstacker 102, 202 and / or of the conveyor 104, 204, and / or of the stacker / unstacker 103, 203 and / or of the incoming auxiliary conveyor 206E is varied.
- the invention provides for slowing down or stopping the first unstacker 102, 202 to allow the insertion of an insert 2. This operation can be completed by changing the speed of mail items 1 and / or tabs 2.
- the inserts 2 may be provided with identification codes, for example in the form of an RFID chip, a barcode or any other equivalent means for identifying the interlayer 2 and associating at this identification, the information relating to the postal items 1 belonging to the stack delimited by the tab 2.
- identification codes for example in the form of an RFID chip, a barcode or any other equivalent means for identifying the interlayer 2 and associating at this identification, the information relating to the postal items 1 belonging to the stack delimited by the tab 2.
- the stacks of postal items 1 and of the dividers 2 are formed in bins. (not shown), these bins can also be identified by means of the identification codes of tabs 2.
- the postal sorting machine can be equipped with a stacker / destacker 103, 203 type FIFO (First In First Out) through which the first stacked interlayer 2 is the first spacer 2 depilated.
- This stacker / destacker 103, 203 FIFO comprises a magazine 400 in which the spacers 2 are stacked on a plate 401 mounted on slides 402 able to move the plate 401 horizontally as stacking of the spacers 2 to leave sufficient room at the back of the stack for stacking subsequent inbound tabs 2.
- This stacker / destacker 103, 203 FI FO also comprises an unstacking mechanism 403 coupled to the plate 401 so that, whatever the state of filling of the magazine 400, the unstacking mechanism 403 remains opposite the first stacked interlayer 2 .
- the unstacking mechanism 403 is thus able to unstack the stacked first interlayer 2.
- the postal sorting machine may also be equipped with a LIFO (Last In First Out) stacker / destacker, not shown, for example similar to that described in publication US 2008/0006509.
- LIFO Last In First Out
- the spacers may also have a shape and / or dimensions different from those of postal items or be made of different materials to facilitate their identification.
- the postal sorting machine comprises a separator stacker and a second unstacker separated and connected to each other, for example by a conveyor, so that the magazine of the stacker can automatically feed the magazine of the second unstacker and that the second unstacker can depilate the spacers previously stacked by the spacer stacker and / or any other insert introduced by any known means in the second unstacker.
- the magazines of the stacker and the second unstacker will therefore not be common.
- the batteries can be recycled in the same sorting machine or in another similar or different sorting machine.
