The device contains a base 1, on the upper part of which a table 2 is installed. At the last, a vibration hopper 3 with an orientator 4 and a transmitting tray 5 is mounted. At the end of the tray there is a measuring station including a spring-loaded two shoulders arm 6, interacting with one end with the measured product 7, and the other with the sensor 8 linear measurements. The lever 6 is connected via a lever 9, t gu 10, a lever 11 and a roller 12 with a cam 13 mounted on a drive camshaft 14. At the position of control there is a pusher 15 fixed on the carriage 16 connected by a pull 17, lever 1 B and roller 19s with cam 20,

In the course of the movement of the pusher 15, a sorting mechanism is mounted on the table, made in the form of levers 21 and 22 and associated electromagnet 23 and 24. In the center of the table 2 is mounted a rotary disk 25 with radial grooves 26 on the upper plane. In the initial position, the longitudinal axis of the groove is a continuation of the axis of the pusher 15. At the end of the groove above the disk 25, a photo-relay 27. is mounted. The rotary disk 25 is fixed on the axis 28 connected via gears 29, the ratchet wheel 30, the pawl 31, the coupling 32, the lever 33 , roller 34 with cam 35. The lever 33 has an auxiliary arm 36, which interacts with a rotary locking pawl 37, associated with an electromagnet 38, In the slots 26 of the rotary disc 25 movably axially mounted crackers 39 with projections 40, the arrangement of which alternates in neighboring breadcrumbs left

and to the right of the groove axis. In diametrically positioned grooves, the protrusions 40 of the rusks 39 interact with the pushers 41 of the rails 42 and 43, which are connected by gear 44.

A magnetization means, consisting of an open magnetic conductor 45 and a coil 46, is fastened under the rotary disk. The upper plane of the magnetic conductor is aligned with the plane along which the blanks move. A clamp 47 is mounted above the disk and is associated with the drive cam shaft. On the side diametrically opposite to the pusher J5, a piece delivery mechanism compartment mounted in the form of a swinging frame 48 with three leading protrusions 49 is mounted.

The frame 48 is harned to a carriage 50 connected by a pull 51, a lever 52 and a roller 53 with a cam 54 located on a camshaft 14. On the latter there is also a fist 55 controlling the roller 56 and the lever 57 by turning the swing of the frame 48. On the way displacements of the oscillating frame 48 are located control-sorting stations for testing magnet 1x properties. The reed switches 58 and 59 are located under the transport track at these stations, and an exemplary magnet 61 is bent under the reed switch 58 on the swing bar 60. The swing arm 60 through the roller 62 is connected to the cam 63 mounted on the camshaft 14.

At the same stations, sorting mechanisms in the form of levers 64 associated with electromagnets are mounted. At the end of the track for moving the suitable magnets, at the position of pushing them into the cassette, a position limiter is mounted in the form of a swinging spring-loaded lever 65 and an adjustable stop 66. At the same position is located the plunger 67 fixed on the carriage 68 connected by a lever mechanism with a cam (not shown) . Coaxially to the pusher 67, there is a receiving cassette in the form of a drum 69, on the side surface of which the through grooves 70 are evenly spaced. A cylindrical shell 71 overlying the open external part of the grooves is mounted on the drum, forming closed channels for accumulating usable magnets. In the front part of the drum, with

The magnets receiving side mounted a locking mechanism in the wake of the rotary disk 72, on the periphery of which there are located locking lugs 73 and hollows 74. A restrictive sheet 75 is mounted on the opposite end of the drum; the drum 69 is mounted on the axis 76 mounted on the supports 77.

At one of the ends of the axis 76, a coupling half 78 is fixed, kinematically connected with the cam of the camshaft 14. On the basis of a photodiode of fixing the filling of the channel of the drum 69 is installed.

The device works as follows.

The billet magnets in the form of rectangular bars are loaded into the vibration hopper 3. The orienting mechanism provides for the issuance of an oriented stream of blanks into the tray 5 and further supplying them all the way to the measuring station. Under the action of a cam

13, the lever 11 deflects and, through the pull 10, rotates the lever 9, which releases the measuring lever 6, the sensor 8 of the linear measurements, detects the deviation of the size of the product 7 from the nominal value. The signal from the sensor is transmitted to the memory unit. With further camshaft rotation

14, the cam 13, through the lever system, lifts the measuring end of the lever 6, releasing the test item.

Subsequently, under the action of the cam 20, the carriage 16 moves through the lever 18 and the tug 17 with the pusher 15 fixed on it, which cuts the controlled part from the workpieces and pushes it to the sorting position, where by turning on the electromagnet 23, the lever 2 rejects the part, having a positive deviation from the nominal. In the next position, the memory unit sends a command to reject a part with an electromagnet 24, which has a minus deviation from the nominal value.

Suitable parts fall into the groove 26 of the rotary disk 25 open from the end, where they accumulate. A signal indicating that the required amount of parts has accumulated in the groove is given by the photo relay 27. An electromagnet 38 actuates, which rotates the locking pawl 37 and releases the spring-loaded lever 3.3, allowing it to interact via the roller 34 with the cam 35. The lever 33 pushes 32 and the pawl

31, the ratchet wheel 30 and gear 29 rotates the disk 25. The parts located in the groove 26 are transferred to the upper plane of the magnetic circuit 45, coinciding with the plane of the table, and are arranged symmetrically to the open magnetic slot. A clamp 47 is activated, a current is supplied to the coil 46 of the magnetization means, a group of parts is magnetized. The magnetized parts are transferred by a disk to the position of issuing magnets from the groove and transferring them to the mechanism of the swinging frame 48.

Parts entering the receiving groove of the height-controlled parts act upon a rusk 39, which, moving to the width of the product, through a sprout 40, act upon the protrusion 41, moves the rail 42 and the second protrusion 41 through the sprout 40 acts upon the rusk 39 and pushes the magnetized part . Under the influence of Shee: Twist 44, the rake 43 makes a reverse movement and to

the end of the stroke takes the initial position, in which its back protrusion 41 fits to the maximally uncovered rusk 39 in the receiving groove 26. Thanks to the protrusion 41 on the slats 42

and 43 is not income t to the axis of the grooves 26, it is possible to provide counter movement of the rails.

Work alternately, rails 42 and 43 provide cyclic delivery of parts from the filled grooves 26 of the rotary disk 25 and transfer them all the way to the first protrusion 49 of the swinging frame 48. The swinging frame 48 performs translational motion and the first protrusion 49 transfers the delivered part to the first control and sorting station. When returning to the starting position, the frame is deflected, ensuring a free approach to the next part. During the repeated cycle, the frame 48 moves the second protrusion 49 to the checked part to the next control-sorting station, and in its place the next part peremeichaet the first protrusion.

At the first monitoring station, the contacts of the reed switch 58 under the action of the reference magnet 61, 3aKpenheHHoro on the swinging shaft 60, are located in

51

closed position. After the magnet is moved to this station, the lever 60 removes the magnet 61 to the distance at which the contacts of the reed switch must open. At the same time, the tested magnet should not re-close the contacts. Thus, the lower limit of the magnetism of the magnet, i.e. located at a certain distance from the reed switch should not affect its contacts.

If the lower magnetization limit is exceeded, the contacts of the reed switch are closed, a signal is given to turn on the electromagnet, which acts on the sorting lever, similar to the size sorting lever

After the controlled magnet is transferred by the frame 48 to the next station, it is checked for maximum magnetization. A suitable magnet should close the contacts of the reed switch 59 located under the transport path. Otherwise, the electromagus electromagnet,. which affects the sorting lever and resets the defective magnet. Valid magnets in a continuous chain move along the track to the position limiter, determining to their place pushing them into the receiving cassette. The position limiter is a compensator for the accumulated error of the linear dimensions of the magnets. The stroke of the frame 48 is slightly greater than the nominal magnitude of the stroke required to move the magnet to the pushing position into the cassette.

During the forward movement of the frame, the chain of magnets slightly leans forward the lever 65, and during the reverse course, under the action of the screw, the lever returns to the stop 66, moving the chain of magnets to the desired position. The cam-lever mechanism for moving the carriage 68 with the pusher 67 operates. The magnet is pushed into the groove 70 of the drum 69 of the cassette. .

After the groove is filled with suitable magnets, the photo relay gives a signal to rotate the drum 69. The electromagnet triggers, which rotates the blocking roving dog, releasing the lever of the rotation drive. Under the action of the cam, the drum 69 is rotated through the lever and ratchet mechanisms through an angle defining the supply of the next free channel.

After filling all the channels, a signal is given to turn off the drive of the device. The disk 72 is rotated so that the protrusions 73 are positioned against the grooves 70. Thus, the filled channels are closed at the ends of the limiting disk 75 and the protrusions 73 of the rotary disk 72. 10 A cassette with unfilled channels is inserted in place of the removed filled cassette.
