Description


[0001] The present invention concerns a mail box associated with a device for the treatment of mailed correspondence.

[0002] The invention is within the field of the treatment of correspondence posted through mail boxes.

[0003] It is well known that correspondence is picked up from each of the mail boxes distributed in inhabited areas and taken to offices for the handling and stamping and re-distribution according to destinations. Stamping takes place after manual selection and alignment of the correspondence based on its format, by introducing stacks of letters into a stamping machine, for example stacks of about one hundred letters. These operations must be conducted on the same day the correspondence is picked up from the mail boxes or the following day.

[0004] The main disadvantages of the above described process consist in the long handling times, the lack of certainty regarding the date of stamping compared to the date of mailing and the high costs; one must especially face:
  • the employment of numerous personnel for the control of staff assigned to emptying the mail boxes and to the stamping of letters,
  • the cost for the purchase and maintenance of stamping machines, tables, etc.
  • the availability of premises suited to these operations.


[0005] The invention, as characterized in the claims herein, is a mail box associated with a device for the treatment of correspondence mailed, and comprises:
  • a connection to the external electricity network and a transformer to lower the voltage of said mains in order according to the characterizing part to feed the following equipment at safety levels;
  • a programmer suited to controlling a first optical means that sees whether a letter that has been correctly mailed and can be accepted, and, in the positive case, that activates the motor of a conveyor means that carries the accepted letter into a device that stamps the letter with date and time, a second optical means that sees whether the stamp put on the letter is correct, and, in the positive case, re-starts the motor, in order to drop the letter to the bottom of the box, a third optical means that checks the level of the pile of letters on the bottom of the box in order to interrupt the handling of correspondence when said level reaches a pre-established height.


[0006] More especially, the mail box may comprise:
  • a connection to the public electric network,
  • a transformer that transforms the voltage of the public electric network to a low operative voltage (e.g. 12 volts) in order to feed:
  • a conveyor means next to a receiving tray in turn next to the slot, so as to allow a user to rest a letter partly on said tray and partly on said conveyor means,
  • an electronic programmer comprising a clock that controls:
  • a first optical reader positioned above said receiving tray that checks that each letter has been introduced with the prescribed orientation and, in the negative case, sends a luminous and/or acoustic signal to the user and, in the positive case, enables the programmer to activate:
  • an electric motor that powers said conveyor means for the time necessary for the letter to arrive and stop under a:
  • stamping device that, a moment after the electric motor has stopped, receives the command to stamp the letter with the date and time continuously updated by said clock and re-starts the motor a moment after the stamp has been impressed to carry the letter under:
    a second optical reader connected to said clock to check that the stamp impressed on each letter is the same as the clock and, in case of correct stamping, activates said electric motor in order to carry forward the letter until it drops to the bottom of the box and, in case of incorrect stamping, activates said electric motor to return the letter to the slot,
  • a third optical reader that checks the level of the pile of letters in the box and causes the rejection of any further mail when the pile reaches a set level by activating said luminous and/or acoustic signal and interrupting the feeding of the motor,
  • a stand-by battery that allows the functioning of the device in case of black-out on the public network.


[0007] It is understood that one unit of such a device can be installed on boxes with only one slot, that two may be installed on a box with two slots, for example one for in-city correspondence and another for that with different destinations, and so on, according to the organization of the postal administration.

[0008] The main advantages of the invention lie in the reduction of the overall cost for the treatment of correspondence and in offering the users and the postal administration a guarantee with regards to the date stamped on the letters.

[0009] Moreover, the device invented can be installed on new mail boxes, appropriately constructed in order to hold such a device, or on existing mail boxes, by means of easy adaptations.

[0010] In order to better understand the invention one embodiment of the same will be described with reference to the drawings attached in which
  • FIG. 1 is a horizontal section of a mail box at the level of the medial plane of the slot, and
  • FIG. 2 is a cross section along I-I of Fig. 1.


[0011] Figures 1 and 2 illustrate a mail box 1 with a single slot 2 protected by a conventional shutter S; an electrical connection 3 between an external electric network and a transformer 4 to feed 12 Volts to a programmer 5 with a clock by means of cable W; at the lower level of slot 2 there is a tray 6 on which to place a letter that is at the same level as the upper band of a conveyor belt 7 stretching between a motor roller 8 and an idle roller 9 held by supports 10; when a letter, not shown, is placed on tray 6 and belt 7, the first optical reader 11 sees that the letter has been mailed correctly, that is with the side bearing the address facing upwards and the part bearing the postage stamps facing left and, in the positive case, activates the electric motor 12 that moves the conveyor belt 7 in the direction of the arrow F for a distance sufficient to carry the letter into the stamping device 13; when the letter has correctly reached the stamping device 13, updated by the clock, said device 13 receives the command to lower the stamp on the letter, after this the electric motor 12 re-starts and the second optical reader 14 checks that the stamp impressed on the letter complies with the correct date and time and then drops the letter L (arrow F1) to the bottom of the box or to reject the letter to the slot 2; the third optical reader, in the form of a photo-electric cell 15, checks the level of the pile of letters on the bottom of the box; when the photo-electric cell intercepts a letter on top of pile 16, a signal to programmer 5 stops the treatment of mailed letters and lights a red bulb 17 set above slot 2 to warn the users.
