Description

The invention relates to mechanical engineering and can be used for automatic loading of metal-cutting machines, assembly machines, automatic lines.

The purpose of the invention is to expand the technological capabilities of the device by ensuring the loading of non-billet blanks, the contacting ends of which have protrusions.

FIG. 1 shows the boot device, the general view; in fig. 2 shows section A-A in FIG. one; in fig. 3-5 - the sequence of operation of the elements of the device in the issuance of the workpiece from the store.

The loading device consists of a magazine 1 with inclined trays 2 for placing workpieces 3, stops 4 and upper limiters 5. The puller for taking the blanks from the magazine is made in the form of rulers 6 having a cutting surface 7 and grooves 8. Between the rulers 6 there is a lever 9 mounted on the axis 10, preloaded by the spring 11 in the initial position to the stop 12 and having a thrust pad 13. On one of the strips of the puller there is a sensor 14. The puller elements are mounted on a brace 15 fixed on the carriage 16, on which axle 17 is installed An independent lever probe 18. The carriage 16 is mounted on a guide post 19 with the possibility of vertical movement from the actuator 20. On the guide post 19, a spring-loaded abutting ruler 21 with a cam 22, throttle 23 is installed in the guide. The store 1 is mounted on a trolley 24 having the ability to move along the guides 25 from the actuator 26. The illuminator 27 and the photo relay are mounted on the rack 19 (Fig. 1 and 2) of the device. The device has a manipulator 29 for removing workpieces from the puller.

The device works as follows.

After the billets 3 load the inclined trays 2 of the magazine 1 and move the carriage 16 upward in the direction of the rack 19 from the actuator 20, the lever-probe 18, resting against the lower row billet, turns in a circle on the axis 17 and with the opposite end engages with the thrust linear 21.

If the workpiece 3 and adjacent to the stops 4 of the tray 2 have an unfavorable overlap for unloading, then the operation of the stripper is carried out in the following

sequences. When moving the puller up to the unloaded workpiece 3, the ruler 6 and the stop platform 13 of the lever 9 touch the lower surface of the workpiece. With further movement of the puller upwards of the ruler 6, I will press on the edge of the workpiece adjacent to the stops 4 of the tray 2, turn it, the end is removed from the stops of the tray. The end of the lever 9, in contact with the opposite edge of the workpiece, stops and the lever rotates at a certain angle, compressing the spring 11. After the end of the workpiece leaves the tray 4, the lever 9, under the influence of the spring 11, rotates to its original position, the ledge of the workpiece to be picked up from under the ledge with gray. Then a puller with braking

it stops as the ruler 21, moving together with the puller and the carriage 16, presses with its cam 22 onto the throttle 23 and stops at the stop. The workpiece, adjacent to the pick-up, comes to the cutting surface 7, and we take

the blank, finally raised above the stops 4 of the tray 2, moves along the platform 13 of the lever 9 to the rulers 6.

If there is no overlap on the unloaded billet from the side of the next one, then the unloading of the billet from the store tray occurs without

turning lever puller. The last one in the tray is unloaded in the tray. The workpiece unloaded from the magazine slides in the puller up to the stop and presses the sensor 14. After that, the carriage under its own weight, and the stop bar 21 descends under the action of the spring, where the workpiece is removed from the puller with the manipulator 29. Thus, all inclined trays 2 stores. The presence of blanks in the store is controlled by a photo relay 28 with an illuminator 27. After their command, the emptied store is driven by the carriage 24 and the actuator 26 along the guides 25 for loading, and the new store with blanks takes its place and the cycle repeats.
