Description

The invention relates to the automation of technological processes and can be used in the field of mechanical engineering.

The aim of the invention is to increase productivity by increasing the likelihood of capturing parts

Fig, 1 shows the device section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - diagram of the forces acting on the part in the process of orientation.

The loading device has a cavity 1 connected to a source of compressed air, bounded by a rotating body 1 and a circular plate 2 having nozzles 3 arranged in a checkerboard pattern, with the outermost row being under the visor 4 two 5 ring hoppers b mounted on the threads 7 1 to change the size of the gap between the visor 4 and the circular plate 2, the bottom 5 being fixed with the latch 8, and the receiving sleeves 9 mounted around the circumference of the restrictor 10 located in the center of the orientation unit. The receiving sleeves 9 are placed in coaxial holes made in the circular plate 2 and the housing 1. Moreover, they are provided with projecting channels B and also have a groove 11 in communication with the atmosphere and are connected to: a receiver 12 where the parts 13 are fed.

The device works as follows.

The parts 13 under the action of gravity force slide off the surface of the circular plate 2 rotating from the shaft 14, where they are affected by the resultant aerodynamic force P (FIG. 3) that occurs when compressed air flows through nozzles 3 from cavity A. Under the influence of the horizontal component aerodynamic force part 13 acquires the speed of the beats and moves to the receiving sleeves 9. The strength of the thrust is the result of the distributed horizontal force qrop created by the horizontal air flow Qro |), arising upon the expiration of air through the nozzles 3, located under the visor 4 of the inclined bottom 5 of the annular bunker 6. The magnitude of the aerodynamic force is regulated by lifting or lowering the threads of the visor 4 of the inclined bottom 5 of the annular bunker B, the gap is fixed by the latch 8 on the hopper 6. The Radhor force also depends on the flow rate, which varies from the flow area of the nozzles 3. When the parts 13 move, the space at the visor 4 is released and the following parts 13 slide down the inclined bottom 5 of the ring hopper 6 onto the circular plate 2, i.e.

-

Parts 13 are automatically taken out of bunker 6 and supplied to receiving sleeves 9. At the same time, during transportation, deoli 13 is affected by the vertical component of the aerodynamic force RadB, which is the result of the distributed force qB that occurs when compressed air flows through nozzles 3.

10 The force Radv is applied to the middle of the part 13, and since its center of gravity is displaced by the amount A, a torque Mvr occurs, the part 13 rotates, adopting a vertical position. Performing nozzles 3 in staggered order, for example, with a step of - d, where d is the diameter of the part

13, ensures the stability of the part 13 during transportation, since

20, the part 13 is constantly in the space bounded by four air jets Q8, having a vertical direction. During the transportation of the parts 13 to the receiving sleeves 9, their active orientation is realized, and since they are turned by more heavy ends under the action of the torque Mvr down and take a stable position, then to the receiving sleeves 9 are served

30 fully oriented parts 13, which eliminates the loading of non-oriented parts 13 and increases the reliability of the device. The process of transporting and orienting parts 13 facilitates rotation

35 circular board 2. When reaching the limiter 10, which is stationary, parts 13 hang under the receiving sleeves 9, since the linear velocity in the center is insignificant and the vertical component

40 of the aerodynamic force, the parts 13 under the action of the force of gravity G fall into the sleeves 9 located around the circumference of the restrictor 10, and then when they fall into the zone of reduced pressure that occurs

45, when the compressed air is exhausted from the cavity A through the ejection channels B, the parts 13 are accelerated and supplied to the receiver 12, and then transferred to the processing. After the parts 13 fall in the receiving sleeves 9 50, an air flow occurs preventing the following parts from falling into the sleeves 9. In order to remove the underpressure area in the sleeves 9, a groove 11 is made, communicating with the atmosphere.
