FIG. 1 shows the kinematical diagram of the automaton; in fig. 2 — rods with measuring transducers, initial position J in FIG. 3, the same at the end of the measuring cycle; in fig. A is a block diagram of a control system; in fig. 5 is a sequence diagram of the operation of the control system. The machine for controlling and sorting parts contains a loading device mounted on the base, made in a vvde vibropattel equipped with a system of reference parts and an outlet tray (not shown) j drive tray 1 installed vertically and transporting mechanism located under the tray 1 in the same plane and made in the form of two mating profiled disks 2 and 3 mounted on parallel shafts 4 and 5 can be rotated. The pitch (f) between the slots of the transporting discs 2 and 3 is chosen depending on the diameter of the part being monitored and the diameter of the discs and is determined by the ratio — the diameter of the part; - disc diameter; D is the chord distance between the near edges of the slots. To ensure the intermittent movement of parts by transporting disks 2 and 3 and fixing the latter, an electromagnetic drive (solenoid) 6 is connected to disks 2 and 3 through a forming mechanism consisting of a rocker arm 7 mounted on a spring-loaded axis 8, a ratchet wheel 9 and a pair of gears wheels 10 and 11. On the shafts of one of the gears, the shutter 12 is installed in the form of a disk with holes around the periphery. The positions of the measuring station are located on both sides of the plane of the transporting discs 2 OF, the first measuring position is installed with the possibility of reciprocating motion perpendicular to the plane of the disks 2 and 3 in the direction coinciding with the movement of the monitored part, spring-loaded rods (pushers ) 13 and 14, and the stiffness of the spring 15 of the rod 13 connected kinematically with the shaft 16 of the electromagnetic drive of the part and the rods is less than the stiffness of the spring 17 (FIG. 1-3). This allows smoothing nonlinearity in the operation of the drive and reducing the dynamic loads on the part and mounted on the ends of the rods 13 and 14 of the transducers 18 and 19 of the surface type. A vortex converter 18 is inserted together with the rod 13 BHyfpb of the part being monitored, and the converter 19 is pressed against its bottom from the outside. At the second measuring position, it is fixed in a plane, perpendicular to the movement of the part, and the measuring transducer 20 (easily removable), which covers (scans) the outer surface of the part. At the exit from the discs 2 and 3, the shutters of the sorting mechanism 21 are located, controlled by their drive.

For information on the movement of mobile transporting and controlling elements, the setting of the moment of issuing information about defects with the moment of the part leaving the photo sensor is set: 22 - for monitoring the overflow of the storage tray 1; 23 for controlling the rotation of discs 2 and 3; 24 to control the movement of the rod 13; 25 — for monitoring the movement of the rod 14. The control device for monitoring and sorting the parts comprises (FIG. 4) a sensor unit consisting of four photosensors 22-25, each of which is connected, via respective signals 26-29, to form signals with a logic element AND 30. For generating the power clock, a clock generator 31 is applied, which via an electronic switch -32 controlled by a logic element AND 33 is connected to a decimal-binary counter 34 pulses, which together with the decoder 35 count, form decade 36, (the OUTPUTS of which are connected to the switch 37, the second inputs of which are connected to the outputs of the control panel 38. The outputs of the switching circuit 37 are connected through a single vibrator 39 and 40 to the mechanism block, made in the form of an actuator 41 for controlling the stems (Control) and an actuator 42 for feeding the disks (Entering ), and the output Reset via logic element 43 and 43 with the second input of the counter 34 in order to eliminate unnecessary moves of the mechanisms. The switches of the control panel 38 allow switching on and off the machine (Start - Stop), switch the machine to Modes of operation: Maximum productivity Multiple control (maximum reliability) Nala, the order manually, the automated reconditioning Transducers 1820 includes the input unit 44 measurements, one output of which is coupled to the analysis unit 45 of the form defects. Through the block 44 measurements, the signals from the transducers are fed to the input of the corresponding logic elements I 46-48, and through them to the circuits of the executive mechanisms of the valves 49-51 with the drive of the sorting valves (for three types of defects). The signal shaping circuit 29 is connected to the measurement unit 44 via the inverter 52. This ensures the synchronization position as well as the return of the measuring station to its initial position. A control device for monitoring and sorting parts and its control system operate as follows. Controlled parts (mainly of the cap type) are pressed into the bowl of the vibro-feeder and, when turned on, under the action of directional vibration, move along the screw tray of the bowl. In the process of orderly movement of parts in the flow, they are oriented on the profiled lugs of the tray and in oriented (unambiguous) positions go to the bypass tray, and from it to the drive tray 1, which has a photosensor 22 controlling the tray filling. Moving profiled discs 2 and 3 capture the parts one by one, reliably base them in the slots and move them to the measuring position. Photo (sensor 23 controls the position of the parts in the slots of the disks 2 and 3 relative to the axis of the measuring transducers 18-20. After the part stops at the measurement position, the electromagnetic actuator 6 is triggered, which through the system of levers and the shaft 16 moves the spring-loaded rod 13c by the converter 18 to its end towards the part. Upon further movement of the rod, the converter enters inside the part and conducts control of the inner surface of the part bottom and the presence of foreign inclusions. Then, under the action of the moving part, the movement begins The rod 14, its transducer 19 rests on the outside of the part from the outside and monitors it. The movement of the rods, overhead transducers and the part is monitored by photosensors 24 and 25. At the same time, the part, the passage inside the pass-through converter 20, is controlled by it. the parts are realized under the action of the compressed spring 17, while the system rod 13 is part - the rod 14 is not kinematically broken, which eliminates dynamic impacts on the part. After all the photosensors give a signal about the completion of moving the moving elements, a signal is sent to the drive SLAVK 11 21 and the drive disks 2 and 3. The control circuit in various modes works as follows (Fig. 4 and 5). Initial position. After a signal is received by the remote control 38, the stop counter 34 of pulses returns. The electronic key 32 does not pass a clock pulse from the clock generator 31 to the counting input of the counter 34 pulses. The storage tray 1 is filled with parts, the spring-loaded rods 13, 14, and the profiled disks 2 and 3 are in the initial position. Sensors 22-25 give the permitting signals. Maximum performance mode. Set the desired mode using the switch on the remote control 38 controls. Switch 37 is connected to the OUT. G decoder 35 to the input of the one-shot 39, O. 2 decoder to the input of the one-shot 40, and Vyh.Z to the exit Reset. Include Start at time t (Fig. 5a.). The first clock pulse of the pulse generator 31 is written into a binary-decimal pulse counter 34 and the output of V.1. 1. The decoder 35 appears to pulse, which triggers the one-shot 39. The control actuator 41 and spring-loaded rods 13 and 14 trigger. . Direct () and reverse () movements of the rods are carried out together with the part. After the rods 13 and 14 return to the initial state under the action of the springs 17, the photo sensor 23, which controls the movement of the first rod, and the photo sensor 24, which controls the movement of the second rod, again produce an enable signal (at time t). Through the electronic key 32 of the ban passes the second impulse from the clock generator 31 pulses. Impulse 2 of the decoder 35 triggers the second one-shot 40, triggers (,) actuator 42 for feeding discs 2 and 3, profiled discs are rotated one step, the next part is inserted, and the checked output (tj-t). When the disks 2 and 3 are fixed in a certain position, the photo sensor 25 controlling the movement of the disks 2 and 3 generates a signal. The third pulse is recorded in the pulse counter 34, a signal () appears on Output 3, it passes the output Reset of the switch 37, as a result 1 counter 34 returns to O. At the moment ts the state of all signals is the same like at the moment i. the cycle repeats again. The multiple control mode (maximum reliability) .. Commzgator 37 performs the following switchings: the number of outputs of the decoder 35, equal to the multiplicity of control, is summed: (logically) and connected to the input of the one-vibrator 39, the next output - to the input of the second one-oscillator 40, and the third exit to exit Reset switch 37. Cyclic loop for this mode — shown in FIG. 5 for the case of triple control. 00 Manual adjustment mode. Pulses for starting both single-shot 39 and 40 are directly fed from control console 38. Automatic setup mode. The switching circuit connects Vyh.1 decoder 35 to the input of the first logic element And 33, Vykh.2 - to the output Reset. Since no pulses are applied to the second one-shot 40, a new part is not inserted. The proposed device is characterized by high performance and sufficient sensitivity to defects throughout the complex cylindrical part; It works reliably both in control and sorting modes, and in manual and automatic configuration of the machine.
