Description

(54) INSTALLATION FOR SORTING POSTAL CORRESPONDENCE It is possible to redirect correspondence to the backup section. The invention is illustrated in the drawings, where in FIG. 1 shows the proposed installation, a general view; in fig. 2 is a block diagram of the installation; in fig. 3 is a schematic illustration of the distributors; FIG. 4 shows a constructive implementation of the distributor module; in fig. 5 and 6 are distribution control circuits; in fig. 7 is a circuit for turning on sensors of control. The installation contains a device 1, which ensures removal of postal correspondence from the foot 2. Installed after the device 1, the reading head 3 reads the code affixed to the correspondence. Unread letters are processed by reader 4 and, via transition module 5, arrive at c. 6. Decoder 7 converts the code defining letters into a special code and sends signals to the control device 8, which controls the transition blocks 9, which ensure the transmission of letters to one from sections 10 and further in the device 11 sorting. The sorting device I1 is made in the form of conveyor lines, divided into segments 12 of such length that each of them cannot contain more than one letter, i.e. the lengths are equal to the smallest possible distance between postal correspondents. At the beginning of each segment is placed the sensor control - photocell 13, which registers the passage of the leading edge of the letter. Each sensor 13 of the control is associated with its register 14. If the sensor 13 of the control registers the presence of one letter in the sorting device 11, its identifying information is registered in the register. When passing by the next sensor, this information is transmitted to the next register, etc., i.e. It is always known at what distance the letter is located and where it is going. GENERAL control of sorting is carried out by a computational mask 15, which also has a buffer memory 16 connected via a contact panel 17 to a calculating machine 15, as well as a number of additional registers 18. The outputs of additional registers 18 are connected to the control devices 8 of each sorting section 19 of the device 11 sorting. Each of the sections 10 is connected by a common conveyor line 20 with a common conveyor 21. A signal about the passage of letters from the sensor 13 of the control through the triggers 22 and 23 enters the converter 24, consisting of several multipliers. 26 clock pulse generator. The output of the converter is connected to the chopper 27, which is connected to the computer 15. The sorting process at the proposed installation proceeds as follows. The passage of mail correspondence is recorded by the sensor and 13 controls, the signal from which via triggers 22 and 23 enters converter 24 and further to computer 15. In registers 18, the address of the letter, information about the letter, information about the status of sections and other control information are recorded. The state of the sensors 13 of the control is stored in the buffer storage device 16. The computing machine checks the receipt of mail correspondence to the sorting device, as well as the filling of each section. When a signal is received about filling the correspondence section, it is sent to the spare section. The functionality of the proposed installation can be easily expanded by introducing additional sections with control sensors and the corresponding number of memory registers connected to the computer. Formula Ieobreten1 Installation for sorting mail correspondence, containing a transport mechanism, receiving sections with mail correspondence distributors, control sensors, a control unit, a memory device and alarm means, characterized in that, in order to improve the reliability of sorting, control sensors are located on the go the movement of the transport mechanism is 1a distance from one another, commensurate with the size of the mail correspondence, and the storage device is electrically connected with the unit This function consists of registers, each of which is connected to a control sensor, with the outputs of the control unit associated with the distributors of the postal correspondence.
