Description

one

The invention relates to the field of chipping and can be used upif automate the loading processes with parts of machine tools and automatic machines.

A device for single-piece dispensing of parts is known, comprising a removable multi-handle cassette with a bottom, a guide tray, a piece-by-piece mechanism, made in the form of a spring-loaded slide, and an actuator.

A disadvantage of the known device is its low reliability, which is especially manifested in single piece details with burrs. Another disadvantage is the impossibility of its use when feeding parts into a device that moves as it does not provide a gap between the part being installed and the ones following it.

The aim of the invention is to improve the reliability of the device

This goal is achieved by the fact that the loading device for single-piece parts containing a removable multi-cassette with a bottom, a guide tray, a single-piece mechanism for parts, made in the form of a spring-loaded slide, and a drive equipped with spring-loaded dogs mounted on the guide tray with the possibility of movement along the axis of the latter, with the bottom of the cassette performed stepwise with an increase in the direction of the zone, with the number of steps equal to the number of streams of the cassette, and each step and performed with a call at a nearby stream.

FIG. 1 shows the described boot device, a general view, in FIG. 2 is a view A of FIG. one; in fig. 3 - multi-cassette; in fig. 4 is a view B in FIG. 3; in FIG. 5, B in FIG. 3, in FIG. 6 — node I in FIG. 3

The loading device for single-piece parts includes a multi-threaded cassette 1, a single piece mechanism 2 and a drive 3.

The multi-cassette cassette consists of body 4, cover 5, gate valves 6, dogs 7 mounted on axis 8 along

the side walls of the guide tray 9. The dogs 7 are constantly pressed by the torsion spring 10 towards the inside of the guide tray, and the spring 11 facilitates directional drawing of parts. Case 4 has a stepped bottom 12, ribs 13 dividing the cassette into streams. The distance between the edges 13 corresponds to the size of the loaded

O details. The stepped bottom of the cassette avoids jamming of parts due to the presence of burrs and height deviations. Valves 6 are inserted into the side openings of the cassette case, protecting the parts from falling out during transportation.

The piece mechanism 2 consists of a body 14, a guide 15, a slider 16, a spring 17, a rod 18, a bracket 19 connecting a rod 18 with a drive 3, a limiter 20. A slider 16 is installed a plate 21, interacting

5 in the extreme position of the slider with the limit switch 22. The spring 17 is in a pre-compressed state to the magnitude of the force required to move the parts. The position of the slider 16 is fixed on the rod 18 by the limiter 20. To secure the multi-strip cassette I on the body 14, the fixing the stops 23, and the multi-cassette cassette are equipped with clamps 24. The parts 25, taken individually from the multi-cassette 1 by means of a slider 16, after they exit from the guide tray 9 fall into the receptacle 26 of the device.

The boot device operates as follows.

The loaded multi-piece cassette 1 is closed by a lid 5, mounted on the housing 14 of the piece-by-piece mechanism up to the fixed stop 23 and secured by the clamps 24. In the side walls of the cassette, the valves 6 are raised

the height exceeds the part size and is fixed in this position.

When air is supplied to the right-hand cavity of the actuator 3, the rod 18 connected via the bracket 19 with the actuator rod will move to the left. The slider 16 through the spring 17 will also move to the left and move the lower row of parts 25 through the tray 9 to

position, when the first part will enter all the way into the receiver 26, mounted in the fixture, for example on the round table of the machine.

Details, moving from one stream to another, at the initial moment due to the difference in the bottom heights freely pass under the priority parts, and subsequently raise each of its own number of parts by the magnitude of the differential.

When it leaves the guide tray 9, the part comes into contact with the pawls 7, which with the help of springs 10 and 1I direct the movement of the part to the receiver 26. With the further movement of the rod 18, the spring 17 is further compressed by the full amount of the load of the rod.

After that, the actuator 3 switches to reverse and the actuator stem moves to the right, moving the bracket 19 and the stem 18 to the right. The slide 16, with an emphasis on the stopper, also moves to the right and moves out of the cartridge to its original position. When the slider 16 returns to its original position outside the cassette, the parts from the last 2 streams fall to the bottom, and the dogs 7 with the help of the springs 10 and 11 displace the lower row of parts from the receiver at a distance of 1311264

necessary to ensure the free movement of the workpiece and the receiver to the treatment position by rotating the table.

5 Then the cycle of movement of the slide 16 is repeated, sequentially releasing the streams of the cassette. When the last part leaves the cassette's leftmost creek on the tray and then moves it to the receiver with slider 16, the latter comes to its extreme left position, while the plate 21, mounted on the slider, presses the limit switch 22 15 and sends a signal to turn off the drive 3 and a signal to replace the cassette with a new one.

Thus, the use of the described device, in contrast to 20 from the known ones, will make it possible to increase the reliability of the piece-by-piece delivery of parts to the fixture with feed to the stop due to the use of spring-loaded dogs in the device, which 25 provide a gap between the piece installed in the fixture and the ones following it. devices, as well as due to the fact that the bottom of the multi-threaded cassette is extra stepped, which eliminates jamming of parts; due to the presence of burrs.
