A device for oriented loading of parts contains (FIG. 1) a feeder 1 with a series of feed trays 2 and an orientation mechanism {FIGS. 1 and 2 including a drive 3, a clutch 4, a double-sided electromagnetic clutch containing half couplings 5 and b with gears mounted on them 7 and 8 and a friction disk 9 located between the half couplings 5 and b. The gears 7 and 8 of the electromagnetic clutch are kinematically interconnected with the gears 10 and 11. In turn, the shaft of the gear 11 is connected via a clutch 12 to the shaft drove 13 with two located on different ends of the latter, zips 14 and 15. Tzhevka 1 drove 13 kinematic and connected with a four-ply Maltese cross 1 rigidly fixed on the tail 17 Tzhevka 15 drove 13 kinematically connected with a four ply Maltese cross 18 fixed on the drum 19.

The gear wheel 10 is kinematically associated with the carrier gear 20, which through the coil 21 is kinematically interconnected with a four-Maltese cross 22 attached rigidly to the drum 23.

The drums 19 and 23 (on the first one the ring sleeve 24 is arranged rotatably) are rotatably mounted in the body 25 of the orientation mechanism. In the annular sleeve 24, radial channels 26-28 are made (FIGS. 3 and 6) for receiving and transmitting parts 29 during the orientation process. This group of channels is made in each section of the sleeve where unoriented parts are loaded. In turn, on the drums 19 and 23, also in each such cross section, there are transverse holes, respectively 30 and 31. In each transverse hole 30 of the drum 19, a grid 32 is installed with a pin catcher 33, with a curved bevel 34 above the latter.

Coaxially with the transverse holes 30 and 31 of the drums 19 and 23 in the housing 25. The channels 35 and 36 are made for supplying parts by means of air. AT

The housing 25 has a stop 37 which overlaps the channel 36 so that the part that falls into the drum 23 cannot twist. In addition, in the housing 25, longitudinal 38 and transverse (vertical) 39 air channels are made. Similar air channels longitudinal 40 and transverse to it 41 (made (fig.Z, 6-8) in the ring sleeve 24, as well as in the drum 19 - longitudinal channel 42 and transverse to it - 43,

For separating and feeding from the reels 19 and 23 correctly oriented parts 29 in the housing 25, discharge trays 44 and 45 are made, under each of which the receiving slots 46 and 47 of the cassette are mounted (FIGS. 3 and 6). On each side of the housing 25, air ports are connected to channels 35 and 36, respectively .48 and 49 (Figures 1-3 and 6). l

To the air channel 40 in the annular sleeve 24, the channel 42 in the drum 19 and the channel 38 in the housing 25 are connected the same air nozzles, respectively 50, 51 and 52 (Fig.7 and 8).

Modifying the grill 32 with the BbjM pin 33 (FIGS. 9 and 10) contains pneumatic channels 53 and 54 and nozzles 55 and 56 fed by squeezing air supplied through channel 57 and 58: made in the drum 19.

Modification of the grid 32 (11 and 12) contains an annular groove 59 and the nozzle 60.

Another modification of the grid 32 with a pin catcher 33 (Fig. 13) contains an inductive coil 61 located on a pin catcher 33, the ends of which are passed through a channel 62 made in the drum 19.

The device works as follows.

A feeder 1 (FIGS. 1 and 2) feeds parts 29 (FIG. 3) through the trays 2, which enter the receiving channel 26 of the ring sleeve 24. Power is supplied to the actuator 3 and the electromagnetic clutch so that its friction disk 9 puts the coupling half into operation with a gear wheel 8. From the latter through the gear wheel 11, the clutch 12, the carrier 13, the choke 14 and the Maltese cross 16 rotates (in the direction of arrow B, FIG. 3) the ring sleeve 24 is 90 °. Thereafter, while the carrier 13 continues to rotate, the ring sleeve 24 is soaring, during which air is supplied in the direction of arrow 3 (Fig. 6) through nozzles 48, channels 36 and 31 into channel 26 of the ring sleeve 24, which acts on the part 29. Like a piston. As a result of this, the part 29 either with O det the pin catcher 33 of the grill 32 installed in the transverse bore 30, as shown in Fig. 6, or is pressed with its blind end into the pin catcher 33, as shown by the dotted line in Fig. 3. Further rotation of the carrier 13 through the bobbin 15 (Figures 1 and 2) and the Maltese cross 18 rotates the drum 19 in the direction (FIG. 6) of the arrow And 90 (since the beginning of the rotation of the drum 19, the air supply in arrow 3 stops), after which the drive 3 is turned off. Air is fed through the pipe 49 (FIG. 8), air channels 40 and 41 (FIGS. 6 and 8) in the annular sleeve 24, which through the transverse hole 30 in the drum 19 and the holes in the grill 32 drops the part 29 from the pin catcher 33 (if it was on it) and directs it to the withdrawal tray 44 (FIG. b) to receiving sockets 46 by deaf TOpliOM down, t, e, in the desired position. If the part 29 was in the position shown in FIG. 3 with a dotted line, then with the rotation of the Bamban 19 in the direction of the arrow I; FIG. B) on 90 (the drum 19 of the wasp: there is such a rotation regardless of the position of the part); bevel. 34 acts on the part 29, which again pushes into the channel 26 of the ring-sleeve 24. In this case, the channels 26 will be aligned (coaxially) with the air channel 43 of the drum 19. Air is supplied through nozzles 51 (FIG. 7) through channel 42 and 43. pushes the part 29 into the transverse hole 31 of the drum 23 until the stop 37; Then turn off the air supply and turn on the reverse of the drive 3, bring the drum 19 and the ring-sleeve 24 to the initial position, turn off the drive 3, and then switch the electromagnetic clutch so that the friction disk engages half coupling 5 with cogs wheel 7, From the latter with the inclusion of the drive 3 through the gear wheel 10, the carrier gear 20, the pin 21 and the Maltese cross 22 rotates the drum 23 by 90 in the direction of the arrow G (Fig 3), which then stops. , the drum 23, its transverse opening 31 communicates with the air channel 39, into which air is pumped through the nozzle 52 and channel 38 (FIGS. 3 and 7), which accelerates the ejection of the now correctly oriented part (with the blind end down) through the discharge tray 45 housing 25 to the receiving slots 47 of the cassette (in the drawing n shown) Thereafter, the drum 23 is driven to its original position, and the system is ready for repeating the cycle.

Thus, during the operation cycle of the device, the parts 29 fill either the slots 46 or the slots 47. The cassette (not shown in the figures) moves one step, and other slots that are filled in the next cycle are fed under the discharge trays 44 and 45. device operation. If under any of the channels came the nest, where

If item 29 is already present, then the next Idetal remains in the outlet trays (channels 44 and 45). This part falls into one of the following cassette sockets. Here, the discharge chutes 44 and 45, which are of the appropriate length, play the role of accumulators. If necessary, the discharge trays 44 and 45 are combined into one common channel, issuing de ± ali 29 into one row of nests, and not into two, as is

0 is shown in FIGS. 3 and 6.

The grill 32 with a winding catcher 33 can be made with pneumatic channels 53 and 54 and nozzles 55 and 56 (FIGS. 9 and 10), through which

5, compressed air is blown out of channels 58 and 57, then parts 29 will play the role of dampers for nozzles 55 and 56. Therefore, when the nozzles 55 and 56 are included in the pneumatic measuring system, they with details 29 will be a nozzle-flap type sensor. This will allow the secondary orientation of parts with very weak signs of asymmetry, t, e. receive

The grille 32 with pin 4, the safety device 33 can be modified (FIGS. 11 and 12) in the form of a disk with an annular air channel 59 and nozzles 60, with the corresponding oriented part being the last gate. Thus, it is possible to orient a sufficiently extensive class of various parts, including parts with small asymmetry and,

In addition to the modifications made in the grid 32 with a pin safety device 33, the latter can carry (Fig, 13)

0 inductive coil 61, which recognizes the position of the parts. The ends of the coil 61 inductance can be bred through the channel 62, made in the cylinder 19.
