The invention relates to a control and sorting technique in mechanical engineering and can be used to sort on the rigidity of flat springs.

The purpose of the invention is the expansion of technological capabilities.

The drawing shows the kinematic scheme of the device.

The device contains a loading mechanism 1, a measuring station 2, a lifting mechanism 3, a rotary sector 4 with a receiving socket 5 and a permanent magnet 6, a spring-loaded rotary lever 7 for resetting with a socket 8 mounted on sector 4, sorting bins 9 and a sector 4 drive consisting of an electric motor 10 connected by means of a coupling 11 and a bevel gear 12 to a shaft 13 on which sector 4 is mounted. The end of the rachaga 7 is connected by a hinge 14 with an electromagnet core 15 aligned coaxially with the shaft 13. Coaxially mounted with the shaft 13lat 16 with reed switches 17 located around the circumference of respectively sorting hoppers 9. Measuring station 2 consists of a movable two-section coil 18 with landing slots at the ends, a suspension spring 19 fixed on the outer diameter in the upper nest of the coil 18, permanent magnet 20 located inside the coil 18, and a measuring system (not shown).

The lifting mechanism 3 consists of an electromagnet 21 and a spring-loaded lever 22 that is pivotally connected to its core and has a tip having a fitting size corresponding to the inner diameter of the measured spring.

The loading mechanism 1 consists of the drums 23 and 24, the drive 25 and the transporting belt 26 with carrier arms 27 mounted on it with tips having a fitting size corresponding to the internal diameter of the spring.

The device works as follows.

In the initial position, electromagnets 15 and 21 and the electric motor 10 are turned off, the rotary lever 7 with the jack 8 is located under the measuring station 2, and the sector 4 with the jack 5 is in the loading position, while the lever 22

of the lifting mechanism 3 is in the uppermost position and with its tip enters the lower nest of the permanent magnet 20, fixing the previously measured spring laid on the inner diameter, laid on the outer diameter in the lower landing nest of the coil 18. The bearing arms 27 of the loading mechanism 1 are filled with springs Bbmie 5 The mechanism 1 and the belt 26 are turned on, moving down one step, putting another spring in the socket 5. At the same time, the electromagnet 21 is activated, the lever 22 moves to the lowest position, laying the measured spring on the way into the socket 8 of the lever 7.

The motor 10 is turned on and the sector 4 is turned so that the receiving slot 5 approaches the measuring station 2. The motor 10 stops, the electromagnet 21 turns off at the same time, the lever 22 removes the spring from the socket 5 with a tip, puts it into the bottom slot of the coil 18 and fixes it in a permanent magnet 20.

The coil 18 is included as a frequency-dependent oscillatory circuit in the oscillator circuit, which allows determining the stiffness of the controlled spring by means of a known stiffness of the suspension spring 19

After the start of operation of the measuring station 2, the electric motor 10 is turned on, which rotates the lever 7 with the previously measured spring until one of the reed switches corresponding to the sorting group is triggered and stops. The electromagnet 15 is actuated, the lever 7 is rotated and the spring is dropped into the corresponding hopper 9.

The electromagnet 15 is turned off, the lever 7 returns to its original position. The electric motor is switched on and brings sector 4 to the initial position, which corresponds to the position g of slot 5 in the loading position, and jack 8 in the measurement positions.
