Description

Apparatuses for sorting correspondence are known that are provided with photocells or a phonograph adapter as receivers. In the proposed apparatus for sorting correspondence, the sensing organ is connected to the electromagnets of the receiving valves by means of a distribution device made in the form of a drum, rotating synchronously with a conveyor belt, provided with movable contacts on the surface that are in contact with the stationary contacts of valve electromagnets. The moving contacts are actuated by electromagnets connected on the one hand to the relay of the receiving organ, and on the other hand to the contact comb on which the brush SLIPS is advanced by a letter on the envelope of which the address is marked with a conditional cipher in the form of darkened squares or knurling.

In FIG. 1 shows an envelope, the rectangular part of which is occupied by the cipher of FIG. 2-scheme of the apparatus.

The proposed apparatus is intended for the automatic sorting of correspondence, in particular letters, the direction of which is indicated by indices applied to letters in the form

cipher acting on the sensory organs of one of the known types.

The cipher (Fig. 1) is occupied by the rectangular part of the envelope, adjacent to its left and lower sides. The dimensions of the rectangular part are constant; the field remaining on top has absolutely arbitrary sizes, and the field to the right MUST be not less than Vn of length occupied by the cipher part. This makes it possible to sort letters of any size, but not minimal (in Fig. 1 it is highlighted by a dotted line). The rectangular part is divided into horizontal lines whose NUMBER is equal to the number of digits (bits) of the index. There are eleven rectangles in the row: the first is an auxiliary one, which is used to determine the correctness of the position of the letter in the apparatus, and ten correspond to the number of different digits in the digit.

On the ciphered letter, all boxes should be filled out and, in addition, one of the rectangles of each line. Thus, the distance of the filled rectangle from the auxiliary rectangle on the left edge of the letter will give a digit, and its distance from the bottom edge will be the digit of this digit.

A device (Fig. 2), used for sorting correspondence with

encrypted indexes as described above, consists of three main parts:

1) a decoder (/, 3, б, 9 and / 5), in which letters are separated and moved, like in stamping machines, with rubber-coated rollers, past the perceiving cipher body, which, through a corresponding relay, transmits the cipher to the memory;

2) a memory device 5, 8 and 7, consisting of a rotating synchronously with the tape of the sorting part of the drum, on the moving contacts of which a letter cipher is dialed, and at the right moments sending current to the electromagnets of the sorting part;

3) the sorting part (75, //, 9, W and 14), moving the letters from the decoder to the accumulators located along the conveyor and having valves for the letters inlet, controlled by electromagnets receiving current from the memory at the time of the letter to the drive.

Due to the presence of a dedicated decoder and its special device, the number of cipher-sensing organs is significantly reduced compared to known systems. The presence of the memory allows you to decipher the index of the next letter, do not wait until the previous one reaches its accumulator, which is intended to create greater productivity of the device without the use of large linear velocities.

Letters to be sorted are inserted into the receiver / (Fig. 2) of the decoder, whence the separator used in the stamping machine is passed into the apparatus in turn.

With the passage of the letter in front of the sensing body 2 synchronously With the letter, the brush 3 of the contactor advances to the relay 4 of the sensing organ 2 alternately with the electromagnets 5 of the Zominator. . The distance between the horizontally interchangeable characters in the letter is proportional to the distance between the contacts of the comb 5, so that when a particular character of the cipher in the letter acts on the sensing organ, the brush 3 of the contactor follows the relay 4 to the corresponding electromagnet 5 of the memory.

In order to avoid sorting a letter if it is incorrectly inserted into the device in a letter, in addition to signs corresponding to the index, the sign of the correct position of the letter in the device is also placed (the first boxes in the cipher description).

This additional sign, through the sensing organ, must act on the additional (in Fig. 2-upper) electromagnet of the memory, which is connected to the additional (in Fig. 2-left) contact of the contactor.

The boundaries of the cipher on the letter are located asymmetrically relative to the edges of the letter; therefore, if the letter is inserted into the machine incorrectly, then the brush 3 of the contactor will come off the additional contact earlier than any of the cipher signs affect the sensing body 2 and the additional electromagnet of the memory; the combination of extended contacts will be incomplete, the letter will pass by all existing drives and will be thrown into the final idle drive // for re-sorting. The movable contacts 7 move in a fixed contact field 8 at a speed proportional to the speed of movement of the letter in the sorting part of the machine. Therefore, at that moment when the contacts 7 are closed with fixed contacts 8 connected to the valve solenoid 9 of the corresponding accumulator, at the same time the letter will be in front of this valve and, therefore, will fall into the corresponding accumulator 10.

The extended contacts, having passed through the entire field of fixed contacts, return again to the electromagnets pushing them in front of which they are smoothed beforehand, i.e. they are moved to the level of the contacts that are not extended (not shown).

Thus, it is possible to sort all the letters by one body perceived by. the number of drives equal to the number of different characters that are in the same category of the index (line

cipher), e. at the tenth indexing system - at ten drives.

If, on the decoder, there are N sensing organs, in the contactor there are respectively N rows of contacts, and in the reminder to make L / sets, each of which will have its own group of pushing electromagnets, a group of pushing contacts and a fixed contact field, then the number of drives in the sorting part of the machine can be increased to a number equal to the number of different elementary characters in the index category raised to the power N. For example, with a decimal indexing system, the number of drives can be be adjusted to 10 A /.

When sorting by several digits, the contacts of the electromagnet of any drive located in several fixed contact fields of the memory are interconnected in series, so that this electromagnet sends a letter to its drive only if the letter cipher converted into a combination of moving contacts parts of the memory, corresponds to the combination of contacts of the drive in the fixed part of the memory.

As the memory contacts pull-up contacts approach to the electromagnets pushing them, the contact 72 closes the electromagnet / 5 circuit, releasing the separator, which pushes the next letter into the device. Due to this moment, the decoding of the letter index coincides with the position of the sliding contacts against the electromagnets pushing them.

In order to eliminate the possibility of sorting the letter due to slip between the tape and the letter, contacts 14 are closed along the entire length of the sorting part, which are closed by the passing letter.

A switch 75 is inserted into the contact circuit J4, which turns on and off some of these contacts at a speed proportional to the speed of the tape.

Thus, if the letter moves normally, then before it closes

the next blocking contact breaks the circuit of this contact by the above-mentioned switch; if the letter is not stuck, and the tape and the associated switch 75 will continue to move, then if there is a discrepancy between the letter and tape movement exceeding the established rate, the switch will close the contact circuit closed by the letter, the electromagnet of the main switch 76 is short-circuited power to the entire machine.

Signals such as a relay with an opening valve are included in the blocking circuit to locate the scene of the incident in large devices.

The subject matter of the invention.
