Abstract

This invention relates to the automation of metalworking machines. The aim of the invention is to improve the performance of the device. This is achieved by the fact that slots 12 formed by curvilinear surfaces are inclined in the drum 1 which is inclined to the horizon, and one of the curvilinear surfaces smoothly mates with the peripheral inner surface of drum 1. with the corresponding main grooves 12. From the hopper 21, the workpieces fall into the grooves 12 and 17 and as the drum i rotates they are drawn upwards and when the grooves 12 periodically overlap with the discharge chute in the oriented position from the corresponding groove 12 to the outlet of the P1II tray, and from the additional grooves 17, the workpieces load the main grooves 12. 3 Il.

Description

This invention relates to the automation of metalworking machines.

The purpose of the invention is to increase the productivity of the device by increasing the capacity of the gripping grooves and the smoothness of the transfer of blanks to the discharge tray.

FIG. 1 shows a loading orienting device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

A discharge chute 20 is installed inside the rod 3, and not one of its ends is a rigidly fixed hopper 21.

To change the angle of the drum I, an adjustment device 22 is provided.

To fix the required angular position of the drum 1 relative to the receiving chute 20 during the return of the pivot arm 6. B

The loading and orienting device CO O is provided with a locking pawl 23, sharpens the inclined drum I mounted with the help of the bearing sleeve 2 on the rod 3, and the rotation drive of the drum 1 made in the form of a pneumatic cylinder 4 hinged to. the plate 5, rigidly planted on the bar 3, and interacting with the ratchet mechanism.

The ratchet mechanism contains a swivel lever 6, freely mounted on the housing 7 of the drum 1 and pivotally connected to the rod 8 of the pneumatic cylinder 4. The pawl 9 is attached to the rotary lever 6, which interacts with the ratchet wheel 10 fixed on the housing 7 of the drum 1.

Nirno mounted on the plate 5 with the ability to interact with the ratchet wheel 10.

The device works as follows.

From the hopper 21, the blanks 16 enter the drum, sink into the grooves 12 and the additional grooves 7, and as the drum 1 rotates they are carried upwards.

With periodic alignment of the grooves 12 20 with the diverting LOTKO-.M 20, the blanks 16 fall out in an oriented nd-place from the corresponding;} from the groove 12 into the tray 20.

The blanks located in the additional grooves 17, rising upwards, begin to descend and gradually slide from the additional grooves 17 onto the peripheral surface 15 of the drum 1, being placed in an oriented position opposite the windows 18.

In the drum I, grooves 12 formed by curvilinear surfaces 13 and 14 are uniformly formed on the inner surface 11, the surface 13 of the groove 12 smoothly mating with the peripheral surface 15 of the drum 1. The distance between the surfaces 13 and 14 of the grooves 12 is made in accordance with the size blanks 16 are usually the smallest, and the depth of the slots 12 is selected on the basis of placing the necessary number of blanks along them along the drum axis to ensure a given performance. Additional grooves 17 are formed between adjacent slots 12, communicating via windows 18 with corresponding main slots 12.

To prevent premature falling out of the blanks 16 from the slots 12 on the rod 3, a cylindrical surface 19 is formed inside the drum, interacting with the slots 12.

A discharge chute 20 is installed inside the rod 3, and not one of its ends is a rigidly fixed hopper 21.

To change the angle of the drum I, an adjustment device 22 is provided.

To fix the required angular position of the drum 1 relative to the receiving chute 20 during the return of the pivot arm 6. B

The device works as follows.

From the hopper 21, the blanks 16 enter the drum, sink into the grooves 12 and the additional grooves 7, and as the drum 1 rotates they are carried upwards.

With periodic alignment of the grooves 12 0 with the diverting LOTKO-.M 20, the blanks 16 fall out in the oriented nd-place from the corresponding;} from the groove 12 into the tray 20.

The blanks located in the additional grooves 17, rising upwards, begin to descend and gradually slide from the additional grooves 17 onto the peripheral surface 15 of the drum 1, being placed in an oriented position opposite the windows 18.

With further rotation of the drum these blanks through the window 18 into the main grooves 12.
