Description

Intelligent letter box

The invention belongs to a kind of postal ﹠ communications equipment.

Existing mail automatic processing equipment, to the length and width of mail, thick, heavy exacting requirements arranged all, because the user often with off-square mail input mail, causes mail can not go up " mail automatic processing equipment " and handles, sophisticated equipment does not normally play a role.And the non-standard mail that a large amount of machines of not going up is handled, postal service still will rely on artificial way to carry out the mail internal affairs and handle, and speed hand-manipulated is slow, and the delivery speed in the mail can not get improving.Because substandand mail is not had to control the means of posting letter, the problem that the user uses non-standard mail to communicate will can not get solving for a long time, so, not only influence the quick transmission of mail, and hindered the development of China's postal ﹠ communications cause automation greatly.Therefore, it is believed that, only take to make non-standard mail can not directly enter the measure of mailbox, just might stop posting letter of non-standard mail, could bring into play the effect of mail automated processing equipment so to greatest extent, realize the automation of postal ﹠ communications cause.People are expecting to have and resist the desirable mailbox that non-standard mail enters the function of mailbox and come out early.

The objective of the invention is at above-mentioned situation, finish a kind of can to the length and width of mail, thick, monitor heavily automatically, the non-standard mail of user's input mail is picked out mailbox then and there, return intelligent letter box to the user.

The method that the present invention finishes is the difference according to the place to use, and post-office box is divided into two kinds of the indoor intelligent mailbox that uses at the post and telegraph office business hall and the outdoor intelligent letter box that use in other public places, and its function, structure are identical.The structure that its mail detects processing equipment by power unit, the Beijing time of connecting with civil power show, unpack that time showing, automatic switch, buncher, conveying mechanism, circuit control, scanning-detecting system circuit card, language are informed, turn-out track valve, counting demonstration etc. partly form.Conveying mechanism and be installed in shell upper with the scanning board of its adapted, photoemission cell, photoelectric receiving tube etc., circuit card and install in the enclosure with civil power bonded assembly buncher etc.The intelligent letter box of this spline structure, from appearance, just both sides in shell upper has drop and non-standard mail to reject mouthful, on the cover board have the simple and easy mailbox of observation window and telltale, detect handle mail operative body mechanism all under cover plate.Its principle of work is first energized, open switch, telltale on the cover plate front shows Beijing time and unpacking time of mailbox, mailbox enters mode of operation, mail is casually dropped into from defeated, electric motor starting can be seen from porthole, and the mail that enters main body mechanism is made uniform movement by front and back load-transfer device clamping.When mail moves with uniform velocity, must block the light that the scanning board directive that light-emitting tube is housed is equipped with the scanning board of light receiving tube, the length that the mail of different size covers light is also different, the electronic circuit (or micro controller system) that the scanning board of adoptor is housed is made logic determines according to the state of mail shading, to length and width, mail thick, that heavily meet national standard during by scanning board the output high level after timing, promote work of electromagnet, and then swing turn-out track valve, the turn-out track valve is posted state for receiving, and reaches mail is received the purpose of posting.Der Standardbrief is posted mouth from receipts and is entered in the mailbox (case), and electromagnet is whenever moving, and once counting machine is just counted once, and the telltale on the cover plate shows has simultaneously received the mail numeral of posting.To the mail that does not meet national standard of input mail, output low level during by scanning board, electromagnet never moves, and the turn-out track valve is the rejection state, and mail is outside rejecting the disallowable case of load-transfer device.When rejecting outside the case automatically to the mail that does not meet national standard, the language circuit working sends the voice of " your mail is nonstandard, now returns ".To disallowable mail, counting machine will not be counted, and also nil shows.

Advantage of the present invention is: (1) is novel in design, simple in structure, easy to make; Especially to the length and width of mail, the detection of thick size, ingenious reliable, scientific and precise; (2) multiple functional, the mail that drops into is met national standard after testing, can in time enter mailbox, counting shows simultaneously; To length and width, thick, heavily do not meet the mail of national standard, reject case automatically outer the time, be furnished with voice, make the user know the problem place of the mail of being rejected, can help the user to increase the standardized knowledge of mail, the effect of publicity is fine; (3) can the actv. minimizing enter mailbox, can bring into play the effect of " mail automatic processing equipment " better, be beneficial to mail and transmit fast, for regulations have been created in the development of postal ﹠ communications cause automation until stopping non-standard mail; (4) can replace the indoor and outdoor mailbox that each big or small post and telegraph office (institute) uses, widely applicable, the huge market demand; (5) can produce good economic benefits and social benefit.
