The device.contains a drive made in B1ade of the toothed rack 8, which is engaged with the toothed sector, 9, mounted on bearings on the rack 3. The drive is interconnected with the hydraulic cylinder iO. The cog rail has a roller stop 1i, adjustable stops 12 for switching the stroke of the hydraulic cylinder 10 and the limit switch block 13,

The device comprises a feeder including a drum 14, having four sockets 15, a ratchet wheel 16 and a growl 17 with a dog 18, a roller retainer 19 and a supporting disc 20,

The device includes a control mechanism consisting of the shaft 21, the core: and. 1sl 22 5 of the damper 23, the lever 24, the installation of the leiiHoro rotatably

The device comprises a storage drum 29 having seven sockets 30, a swivel bar 31 fixed to papal 7 connected to a gear sector 9, a cutter containing a fixed disk 32 with holes 33 (a dump valve 34 in which half apertures 35 are made, and have A stop 36 and a adjustable stop 37. The fixed disk 32 and the reset flap 34 are located in the same plane. In addition, there are two roller clamps 38 and 39.

The boot device works in 1-minute mode.

Shptyka is fed from the vibroblucker channel. Pin 5 subject to orientation,. gets into one of four four CX jacks 15 of the drum 14 and is J position 1 (fig / o.

From the position shown on the fkg 1 - 3, a gear rack 8 of the device drive under the rod of the hydrodilidir rod iO var schaets

To the right and through the toothed sector 9, the lever 17 with the pawl 18 rotates the ratchet wheel 90 90, causing the drum 14 to rotate and the pin from position I is transferred to position II (Fig.) To control its orientation, and the drum 14 is locked with locking pin 19. In this movement of the toothed rack 8, the stop 11 for the yoke 22 rotates the shaft 21, and with it the valve 23 and the lever 24, thereby closing the pin out of the socket 15 of the drum 14 into the socket 30 of the storage drum 29, and pulls the spring 28. At the same time with these movements, the shaft 7 is rotated and with it turntable 31. If in the slot 30 of the storage drum 29 there is an oriental pin which fell into it in the previous cycle, then the turntable 3 engages this hairpin by the end protruding beyond the lower plane of the storage drum 29, and together with the stud rotates it into a part of the circle, bringing the next free nest 30 under the nest 15 of the drum 14, and the storage drum 29 in this position is locked by one of the roller retainers 39. If in the DOR slot of the storage drum 29 is oriented pin from the previous center If there is no valve, the turntable 31 does not rotate the storage drum 29, i.e. makes idling. During the reverse movement of the toothed rack 8, the turning bar 31 returns to its original position, the roller stop 11 moves away with the toothed rack 8 to the left, and the shaft 21 rotates counterclockwise under the action of the spring 28, causing the sensitive elements to check the thread pitch of the stud in slot 15 of drum 14 in position II. If the stud is oriented correctly, i.e. the depth and pitch of its thread coincide with the depth and pitch formed by the sensitive element, then they, slipping along the side of the surface of the thread, swing together with the lever 24 around the axis 25 in the vertical axis and together with the axis 25 in the horizontal plane x x x (t The lever rotates around the intersecting axes, the perpendicular of the axis of the pin) will find a place on the hairpin, where it misses them, and the damper 23 turning with them opens the path for the hairpin to the slot 30 of the storage drum 29. If the pin oriented wrong., i.e. its thread pitch and thread depth are shorter than that determined by the location of the sensing element 26, then they are stopped by the stud, and the rotation of the shaft 21 is stopped, the flap 23 does not open the way for the stud to the socket 30 of the storage drum 29; and the pin remains in the slot 15 of the drum 14, from where, through a diclary, it, being in position III (Fig. 1), falls out of it onto the tray and is conveyed to the transport device feeding the bunker. When filling the sockets 30 of the storage drum 29 with a predetermined number of studs that form a set simultaneously supplied to the assembly, it is transferred to its constructive dimensions: from the kit, the stud in the turn of the storage drum 29 approaches the stop 36 and interacts with it From the latch 39, the dumping flap 34 and transfers it to the position in which its half-holes 35 coincide with the holes 33 nevertheless this number must always be; one unit more than the number of units in the maximum set, which can be reduced to two parts by the permutation: vnopa 37, located on the reset valve 34.
