FIG. /

1680378

The invention relates to the automation of the processing of written correspondence and can be used when transporting letters, postcards, forms in letter sorting machines in postal enterprises.

The purpose of the invention is to increase productivity.

. FIG. 1 shows a sorting machine, general view; fig 2 - section aa on fig. one; in fig. 3 is a section BB in FIG. one.

The sorting machine comprises a conveyor conveyor 1 with carriages 2 formed by two leaves: a fixed leaf 3 and a movable leaf 4 installed with the possibility of opening. Sash 3 and 4 are fixed on the housing 5. The accumulators 6 of the sorting machine are mounted on the frame 7, on which they are fixed in front of the accumulator 6, the stop 8 and the lever 9 on one bracket 10. The carriage 2 is equipped with a roller 11 rigidly fixed on the axis 12, intended for forced ejection of a flat object (letter) 13, and an accelerating unit, for example, a friction mechanism. designed to increase the speed of the roller, made in the form of three wheels 1416, and the wheel 14 and the wheel 15 are rigidly connected. Wheels 14 and 16 have a V-belt profile, wheel 15 has a V-belt profile for better grip. To obtain the required speed of rotation of the roller 11, the ratio of the radius of the wheel 15 and the radius of the wheel 16 must not be less than 3. The wheel 16 is rigidly fixed on the axis 12 of the roller 11. In the fixed sash 3 U-shaped slots are made and part 17 of the sash 3 is bent to the side of the movable sash 4. The free end of part 17 of the flap 3 is at the level of the plane of the vertical axis of the roller 11. To open and close the flap 4, the carriage 2 is equipped with a dog 18. The stop 8 and the lever 9 are actuated by an electromagnet 19. The axis 12 of the roller 11 rotates in sleeves 20 pressed into the core mustache carriage.

The device works as follows.

The letter 13 is located in the carriage 2 and is located at an angle, clinging to the shutter 4 and leaning on the roller 11. Part 17 of the shutter 3 does not allow the letter 13 when being inserted into the space behind the roller 1.1. The flap 4 is held by the dog 18.

The carriage 2 with the letter 13 is moving with the pull chain of the distribution conveyor 1. _

When the carriage 2 approaches the drive 6 from where the letter 13 is to be thrown, a command comes from the control system (not shown) and the electro5 magnet 19 closes. The stop 8 with the lever 9 rises together with the bracket 10 and the wheel 14 hits the stop .8, made with the profile of the V-belt for better grip, and the wheel 14 with the wheel 15 begins a circular movement. The wheel 15 due to friction starts to rotate the wheel 16, which rotates the roller 11, and simultaneously with the start of movement of the accelerating unit, the lever 9 opens the pawl 18 and the flap 15 4 opens. The roller 11 rotates in the sleeves 20 towards the ejection of the letter 13 and due to the friction of the roller 11 against the plane of the letter 13, adds acceleration to the letter, which begins to fall under its own weight at the time of opening the flap 4. The flap 4 gives the letter 13 a directional motion.

To reduce the linear dimensions of the sorting machine, the carriage 2 can be made symmetrical with respect to the horizontal axis. The transporting conveyor can be positioned due to the symmetrical design of the carriage in tiers, which allows to reduce the linear dimensions of the machine.

30 Thanks to the use of the proposed technical solution, an increase in productivity of the sorting machine is achieved due to the forced ejection of a letter from the carriage.
