Abstract

 The invention relates to a machine tool industry, namely to devices for automatic loading of technological machines with piece parts, and can be used to feed parts such as disks to a rotary conveyor machine. The aim of the invention is to enhance the functionality of the rotary power supply by providing orientation of flat parts such as discs with an unsupported facet on one of its surfaces. When the rotary automat rotates, the part 6 is fed through channels to the piece feed mechanism 11 and the latter is pushed between two rotating rollers 14 relative to each other. At the moment the back edge of the part 6 interacts with the rolls 14, the front edge of the piece deviates from the piece feed mechanism to the side, opposite to the chamfer, going beyond the tip of the dissector 16. With the further movement of the single-piece feed mechanism, the part 6 is pushed into the corresponding through groove 15 of the tilter 13, and then passes into the hole in the bar and in the tray or after turning the tilter 13 to align the groove 15 directly with the window, the part is unambiguously oriented, in the tray, the tray. Subsequently, the parts 6 accumulate in the tray and enter the dispensing position. When the turn-over device is in the form of a tray divided into two parts by a wedge surface, at the moment the back edge of the part 6 interacts with the rollers 14, its front edge deviates from the axis of the piece-feed mechanism 11 to the side, the tip of the wedge point and pushes the part 6 into the corresponding the part of the tray where it takes a vertical position and slides along the spiral surface of the tray. Next, parts from the two streams are combined into one stream and fed to the dispensing position. 3 3 about p. F-ly, 11 ill. s (L O5 00

The rotor power supply unit contains a disk 2 and a hopper 3 fixedly mounted on the shaft 1 and a hopper 3 mounted coaxially above it, to the bottom of which a ring 4 is attached with channels 5 evenly spaced around the circumference to capture parts 6. The ring 4 is fixedly mounted on the drum 7, mounted on a hollow shaft B, rotated by a drive gear 9 secured on it. Q Channels 5 are connected by vertical trays 10 to single piece mechanisms 11, in the path of which mechanisms 12 are detected which recognize the position of the part behind which tilters 13 are installed. 35

The mechanism 12 for recognizing the position of the part is made in the form of two rollers 14, spring-loaded to each other and installed so as to

and a disk 18. In the drum 17, the sliders 1 are arranged evenly around the circumference and are made in the form of rails, which interact with their rollers 20 by a stationary cylindrical groove cam 21 fixed on the base 22 of the machine and are driven in a gate-translational motion and kinematically connected through gear 23 with the corresponding mechanism 11 piece feed. The mechanism of the single piece feed through the spring 24 moves the rail 25, which rotates the bar bar all the way (not shown) around the vertical axis. Under each tilter 13, the bar 26 with the profile window 27 is mounted with one of its grooves 15.

The tilter 13 can be made in the form of a tray 28 divided by a wedge 29 into two parts. The tip of the cell at 29 is addressed to the mechanism of the output drawing,

The details of the tray 28 are fed to the delivery position, where the extreme part is held by the spring-loaded sponge 30 and the spring-loaded pusher 31 interacting -1M during rotation of the dial 18 with its roller 32 with a fixed copy 33,

Under the cantilever 13, see the tire strap 26 with the profile about 27 under one of the slots 15 and the fold 13, and the tray 34 is mounted under each rail 26.

Rotary power supply works as follows.

The drive mechanism (not shown causes the rotation of the shaft 1 and closed

free rotated in a plane, a friction disk 2 worn on it,

part 6 plane supplied by ex-shan 11.

The tilter 13 is made in the form of a reciprocating reel with two grooves 15, disengaged symmetrically with respect to the vertical plane passing through the axis of the mechanism 11 of the single piece, at an acute angle to each other. The partition is 50 ka chalk food grooves 15 is made in the form of a dissector 16, the tip of which is directed towards the parts supplied by the mechanism 11 of the piece. Forming the grooves 15 made in the form of 55 radius curves, the extreme points of which are located respectively on the end and forming the drum. A drum 17 is also mounted on the shaft 8

Parts 6 are loaded in bulk into the bucket Zo. From the drive of the rotor-conveyor machine (not shown), through the wheel 9, the shaft 8 is rotated, and together with HiiM the drums 17 and 7, disk 18, ring 4 are fed to the hopper 3. The forces of 6 move to the periphery of the dis 2 and fall into the channels 5 of the ring 4, which translate them from horizontally to the vertical. Beyond that, parts 6 along vertical tray 10 are fed to mechanisms 11 of the wire feed. The slider J9 moves the feed mechanism 11 through the pin 23. The latter, through the springs 24, moves the rail 25, which turns the raban up to the stop (not shown) around the vertical axis, i.e.

and a disk 18. In the drum 17, the sliders 19, arranged in the form of rails, which interact with their rollers 20 with a stationary cylindrical groove cam 21 mounted on the base 22 of the machine, are placed in a reciprocating motion and are kinematically connected through gear 23 with the corresponding mechanism 11 piece feed. The mechanism 11 of the piece-feed through the spring 24 moves the rail 25, which rotates the drum around the vertical axis to the stop (not shown). Under each tilter 13 a strap 26 is mounted with a profile window 27 under one of its grooves 15.

The tilter 13 can be made in the form of a tray 28 divided by a wedge 29 into two parts. The edge of the wedge 29 is drawn to the mechanism of preschool issuance,

The parts but the tray 28 are fed to the dispensing position, where the extreme part is held by the spring-loaded sponge 30 and the spring-loaded pusher 31, interacting -1M as the disk 18 rotates with its roller 32 with the fixed cam 33,

Under the cantilever, 13 tiller plate 13 with a profile window 27 under one of the slots 15 of the tilter 13, Tray 34 is mounted under each bar 26.

Rotary power feed is as follows-.

A drive mechanism (not shown) causes the rotation of the shaft 1 and the friction disk 2 fixed to it,

Parts 6 are loaded in bulk into the bunker. The drive of the rotor-conveyor machine (not shown) drives the hollow shaft 8 through gear 9, and together with HiiM drums 17 and 7, disk 18, ring 4 into the hopper 3. Under by the centrifugal force of the part 6, they move to the periphery of the disk 2 and enter the channels 5 of the ring 4, which transfer them from the horizontal position to the vertical position. Then, the parts 6 along vertical trays 10 are supplied to the mechanisms 11 of the single piece. J9 slider over gear-. nu 23 moves the mechanism of the piece 11. The latter, through the spring 24, moves the rail 25, which turns the drum around the vertical axis to the stop (not shown), i.e. ba514687

The raban is in its original position for receiving the part. During the further working stroke, the mechanism of single-piece feeding compresses the spring 24 and pushes the lower part 6 from the tray 10 between the rollers 14, the compartment and the column of the part in the block 10. At the moment when the rear edge of the part 6 interacts with the rollers 14, its front edge deviates io is away from the axis of the mechanism 11 of the single-piece feed in the direction opposite to the facet (convexity), approach beyond the tip of the splitter 16, and with further working stroke, the mechanism of the single-feed 15 pushes the part into the corresponding through groove 15 of the drum.

If the part 6 is in a position in which the chamfer (bump) is located on its left side, then its 20 leading edge deviates to the right from the axis of the mechanism 11 of the one-piece feed 1 1 and the part is pushed into the right groove 15 of the drum, under which in the fixed bar 26 There is a hole of rectangular cross section through which the part enters the tray 34. If part 6 is in a position where the chamfer (bulge) is located on its right side, then its front edge deviates to the left from axes of the mechanism 11 of the single piece and the item zata nods into the left groove 15 of the drum in which it remains, being on the bar 26, since there is no hole under the left groove in the bar 26 connecting it to the tray 34. When the feed mechanism 11 of the piece 11 is idled (retracted), the spring 24 is opened and the piece-feeding mechanism 11 pulls back the rail 25, which rotates the drum to align the left groove 15, in which the part 6 is, with the hole of the bar 26, behind the rod head (FIG. five). Thus, the part is reoriented, and it is in position, in which the chamfer (bulge) is located on its left side, enters the tray .34 through the hole in the bar 26.50

In tray 34, unambiguously oriented parts are penetrated, moving along the tray, transferred from the vertical position to the horizontal position, in which the chamfer (bulge) is located on the bottom surface of the part, and arrive at the position where the end part is 6 held by a spring loaded sponge

30. From the position of delivery, the extreme part 6 is fed to the working position of the rotor-conveyor machine (line) by a spring-loaded pusher 31, which interacts with the roller 32 with the roller 32 with the stationary ring copier 33 mounted on the base 22 of the machine. When the tilting device is in the form of a tray 28 at the moment when the back edge of the part 6 interacts with the rollers 14, its front edge deviates from the axis of the mechanism 11 of the single piece in the direction opposite to the facet (bulge), beyond the point of the wedge 29, and during further progress the mechanism 11 of the single piece pushes the part into the corresponding part of tray 28, where it assumes a vertical position and slides down along the spiral surface of the tray. Further, parts from two parts of the tray are combined into one stream of uniquely oriented parts, accumulated in tray 34, advancing along it, taking a horizontal position at which the chamfer (bulge) is located on the bottom surface of the part, and arrives at the dispensing position.
