Description

Referring to the invention as an example for supplying parts to the working area of a technological machine, it can be used in any branch of mechanical engineering, in instrument-making, and in the watch industry, for example, in machines intended for assembling threaded and riveted joints. .

A device for supplying parts by means of hedgehog air is known, which contains mechanisms for gripping and transporting parts to the working body, made in the form of a hollow rod, interleaving inside a power shaft} P1Dra 1.

1-1 is a disadvantage of the known device; the limitations of the sizes and configuration of the HiCjiopted parts, as well as the possibility of loss of orientation of the parts when they are captured, for example, the details of the widths of the elements.

 Moreover, the device is cumbersome and complex (0, since the vacuum grip is located directly on the rod of the cylinder, consequently, the movement of the gripped part in the space is limited both by; 1a | razmerno, and the size of the piston stroke, limited by the dimensions of the pneumatic cylinder.

The 1-1vestand is also a device for automatic feeding of parts that is closer in terms of technical essence, and is reinforced on the ground (a transport tube connected to a source of compressed air and connected: the first mechanism of the continuous delivery of blanks and the gripping body 2.

However, known devices, but provide iodac flat parts, for example d ;;

; over; 1ioi. as well as clock screws and others

similar parts without repair

nli jammed; and them in transport T: Sponge.

The price of the proposal is to prevent) 1In the wedge; 1n parts in the transport tube.

This is achieved by the fact that the device has a supply: that is, that is, inside the tube, with possible ;; along its axis under the action of compressed air onoroy. supporting part K1 of the piece to be imported, and sub) ugshgennoy, established coaxially with the transport tube from the side of communication with the gripping body with a slider with a receiving opening iodor connected to the compressed air supply unit 10C - :. not) ed1en; .1I in a plane, perpendicularly. to the axis of the transport tube, under the action of 3 a X in a t; go go about organ.

The drawing shows the device section.

O; io contains reinforced on the basis of

/ tra; Snort; 1 and 2 tube connected through a 3 3 4 iputserov air source (not shown).

The tube 2 connects the mechanism for the piece-by-piece dispensing of the parts entering the slot 5 from the orientation device (not shown in the drawing), and the gripping member 6. The support tube 7 is placed in the transport tube 2, to which the feed piece 8 is pressed with compressed heat.

Coaxially with tube 2, a slider 9 is installed with a hole under it, showing 1P the final position of the dotted lines: pl. The slider 5 is spring-loaded by the spring 10, and its initial position is determined by the stop //. The gripping organ 6 is moved along the lamppost 12 based /.

The device works as follows. When compressed air is supplied through the shaper about the part 8, which is located in the nest 5, together with the support 7 it moves along the transport tube 2 until the support 7 rests into the bottom of the receiving hole of the slide 9. Since the opening of this hole is equal to the length of the support 7 the upper end of the supplied part at the end of transportation will be pa level with the plane 12 of the base /.

After that, the gripper opiaH 6 moves in the direction of the arrow A, shifts the slider 9 together with the onor 7 inside it and is positioned against the opening of the transport tube 2. The transported part enters the receiving part of the gripper O: 6 nal you: leads the UIM from the transnational tube. In this case, the slider 9 with the support 7 under the action of the spring 10 returns to its original position, determined by the stop 11, and the onor 7 is again located under the opening of the main tube 2.

The compressed air supply through the nozzle 3 is turned off and the compressed air supply is turned on through the nozzle 4, under the action of which the support 7 returns to its original position and rests on the next part. Last by this time should be in the nest of the feeder 5.

Then, the entire cycle of feeding the parts is repeated.

During the movement of the part owl, locally with support, the part with its upper end presses against the lower end of the support. And, since the support size match is selected

in such a way that it cannot turn over or wedge in the transport tube, then the transport port also sticks to it, while moving, its oriental position, in which it is not in the nest of the feeder.

The described device is easy to fabricate and operate, has high efficiency and can be widely used in the supply of small parts with one-sided signs of orientation.
